The transverse axis Y is substantially the direction along the width of the robotic cleaning device, with the direction of the arrow along the transverse axis Y being denoted as "left" and the direction opposite the arrow along the transverse axis Y being denoted as "right". The vertical axis Z is in a direction extending upwardly from the floor of the robotic cleaning device. As shown in fig. 1, the direction along the front-rear axis X is defined as a second direction, for example, a forward direction or a backward direction, and the direction perpendicular to the second direction in the horizontal plane is defined as a first direction, for example, a left direction or a right direction.
A control system (not shown in the figure) is disposed on a circuit board in the mobile platform 1000, and includes a non-transitory memory, such as a hard disk, a flash memory, a random access memory, a communication computing processor, such as a central processing unit, an application processor, and an application processor, where the application processor is configured to receive the sensed environmental information of the plurality of sensors transmitted from the sensing system, draw an instant map of the environment where the automatic cleaning device is located according to the obstacle information fed back by the position determining device by using a positioning algorithm, such as SLAM, and autonomously determine a driving path according to the environmental information and the environmental map, and then control the driving system 3000 to perform operations such as forward, backward, and/or steering according to the autonomously determined driving path. Further, the control system may also determine whether to start the cleaning module 5000 to perform the cleaning operation according to the environmental information and the environmental map.

As shown in fig. 2, the cleaning module 5000 includes a dust box, a blower, and a main brush module. The main brush module cleans the garbage on the ground in front of a dust collection opening between the main brush module and the dust box, and then the dust box is sucked by the suction gas generated by the fan and passing through the dust box. The dust removal capability of the sweeper can be characterized by the sweeping efficiency DPU (Dust pickup efficiency) of the garbage, the sweeping efficiency DPU is influenced by the wind power utilization rate of an air duct formed by a dust collection opening, a dust box, a fan, an air outlet and connecting parts among the dust collection opening, the dust box, the fan and the air outlet, and is influenced by the type and the power of the fan, so that the sweeper is a complex system design problem. The improvement in dust removal capability is of greater significance for energy-limited cleaning automatic cleaning equipment than for conventional plug-in cleaners. Because the dust removal capability is improved, the energy requirement is directly and effectively reduced, that is to say, the original machine which can clean the ground of 80 square meters after charging once can be evolved into the machine which can clean the ground of 180 square meters or more after charging once. And the service life of the battery with reduced charging times can be greatly prolonged, so that the frequency of replacing the battery by a user can be reduced. More intuitively and importantly, the improvement of dust removal capability is the most obvious and important user experience, and users can directly draw a conclusion on whether the dust is cleaned/rubbed clean.

The second protruding points on the second brush 232 are uniformly distributed along the extending direction of the surface of the second brush 232, and the second protruding points 2321 can increase the friction force between the brush member and the garbage, so that the cleaning is cleaner.
In other embodiments, the first brush member in the first roller brush 100 and the second brush member in the second roller brush 200 may be different, and may be specifically configured according to the cleaning requirement. Alternatively, the first rolling brush 100 is a brush, the second rolling brush 200 is a rubber brush, and the combination can meet the cleaning effect of various ground environments, namely, the good cleaning capability of the brush to hair or fine soft fibers is utilized to clean garbage on soft ground such as carpets, and meanwhile, the good cleaning capability of the rubber brush to hard ground is utilized to clean the ground such as floors and tiles.
In some embodiments, the outer diameter of the second shaft member is less than the outer diameter of the first filler and/or the outer diameter of the second shaft member is greater than the inner diameter of the first filler. Since the second rolling brush is of an incompressible hard core structure, in order to avoid the large particle garbage passing property from being greatly reduced due to the incompressible hard core structure, the blades of the second rolling brush are required to be provided with a longer length than those of the first rolling brush, the distance from the outer diameter of the second shaft part (hard core) of the second rolling brush to the ground is not smaller than the distance from the outer diameter of the first filler (soft core) of the first rolling brush to the ground, and at the moment, the outer diameter of the second shaft part is required to be smaller than the outer diameter of the first filler. In addition, when the outer diameters of the second shaft part (hard core) of the second rolling brush are further reduced, the outer diameters of the first brush part of the first rolling brush and the second brush part of the second rolling brush are the same, the corresponding second brush length is gradually increased along with the reduction of the outer diameter of the second shaft part (hard core), if the length of the second brush is beyond a reasonable range, the cleaning force is weakened due to the fact that the second brush becomes suspended, the surface area of the second brush is increased, so that the second brush is easier to adhere dust to influence the cleaning effect, and therefore in order to ensure the cleaning effect, the length of the second brush is not too long, the outer diameters of the corresponding second shaft part (hard core) are not too small, the outer diameter of the second shaft part is larger than the inner diameter of the first filler, and the second brush is ensured to be in a proper range.
In some embodiments, the first filler has a lowest point lying in a plane lower than a plane in which the second shaft member has a lowest point. Because the first filler has compressibility, in order to guarantee the trafficability characteristic of rubbish below first round brush and second round brush, need make the plane that the minimum place of first filler is located be less than the plane that the minimum place of second axle part was located, when first round brush is the front round brush, because first filler can be compressed thereby can guarantee the trafficability characteristic of rubbish, when the second round brush is the front round brush, because the minimum of second axle part is higher, still can guarantee the trafficability characteristic of rubbish, simultaneously, because first round brush is the back round brush and is nearer from ground, can intercept rubbish and be difficult for spilling from first round brush below, cleaning device's cleaning efficiency has been promoted.
In some embodiments, the first brush extends from the first tubular member outer surface in a direction away from the first tubular member a furthest distance less than the second brush extends from the second tubular member outer surface in a direction away from the second tubular member. As mentioned above, since the outer diameter of the first filler is larger than the outer diameter of the second shaft member, if the length of the first brush is not smaller than that of the second brush, the whole first rolling brush is larger, and the interference between the first brush and the ground is greatly increased under the condition that the assembly positions of the first rolling brush and the second rolling brush are approximately positioned on the same horizontal plane, so that the noise formed by the first brush beating the ground is increased, the resistance is increased for the travelling process of the automatic cleaning device, and the automatic cleaning device is inconvenient to execute cleaning tasks.
In some embodiments, the outer contour of the first brush member that is formed furthest from the outer surface of the first tubular member in a direction away from the first tubular member forms an outer diameter of the first roller brush, and the outer contour of the second brush member that is formed furthest from the outer surface of the second tubular member in a direction away from the second tubular member forms an outer diameter of the second roller brush, the outer diameter of the first roller brush being approximately equal to the outer diameter of the second roller brush. When the assembly positions of the first rolling brush and the second rolling brush are approximately positioned on the same horizontal plane or have little difference, the first rolling brush and the second rolling brush can be ensured to have enough interference quantity with the ground, and the double-brush cleaning effect is achieved. In addition, for the automatic cleaning equipment in the non-working state, the double rolling brushes in the storage state can be stored in the cleaning module in a substantially flat mode, and design and processing complexity caused by inconsistent designs of the front cleaning brush installation position and the rear cleaning brush installation position are also reduced.
In some embodiments, the distance between the axis of the first roller brush and the axis of the second roller brush is no greater than the outer diameter of the first roller brush and/or the second roller brush, e.g., the distance between the axis of the first roller brush and the axis of the second roller brush is less than the outer diameter of the first roller brush and/or the second roller brush. When the outer diameters of the first rolling brush and/or the second rolling brush are approximately equal, and the distance between the axis of the first rolling brush and the axis of the second rolling brush is larger than the outer diameter of the first rolling brush and/or the second rolling brush, the first brush piece and the second brush piece have no interference effect, so that garbage cleaned between the first rolling brush and the second rolling brush cannot be rolled up smoothly, and the overall cleaning effect of the cleaning equipment is affected.
In some embodiments, the outer contour of the first brush member that is formed from the furthest extent of the outer surface of the first tubular member extending in a direction away from the first tubular member forms the outer diameter of the first roller brush, the outer contour of the second brush member that is formed from the furthest extent of the outer surface of the second tubular member extending in a direction away from the second tubular member forms the outer diameter of the second roller brush, and the distance between the axis of the first roller brush and the axis of the second roller brush is no greater than half of the sum of the outer diameters of the first roller brush and the second roller brush. For example, when the distance between the axis of the first rolling brush and the axis of the second rolling brush is smaller than half of the sum of the outer diameters of the first rolling brush and the second rolling brush, and when the outer diameters of the first rolling brush and/or the second rolling brush are unequal, and the distance between the axis of the first rolling brush and the axis of the second rolling brush is larger than half of the sum of the outer diameters of the first rolling brush and the second rolling brush, no interference effect exists between the first brush piece and the second brush piece, so that garbage cleaned between the first rolling brush and the second rolling brush cannot be rolled up smoothly, and the overall cleaning effect of the cleaning equipment is affected.
In some embodiments, the minimum distance from the first filler inner diameter to the second shaft member outer diameter is greater than the difference between the first filler inner diameter and outer diameter. When the inner diameter of the first filler is too large, or the outer diameter of the second shaft part is too large, so that the minimum distance from the inner diameter of the first filler to the outer diameter of the second shaft part is too small, the flexible space allowed to pass between the front brush and the rear brush is reduced, slightly large garbage, even flexible garbage, can be clamped between the two brushes and cannot enter and exit the dust box, the limiting distance is that the outer diameter of the second shaft part is in contact with the outer diameter of the first filler, and at the moment, although the first filler still has a compressible space allowance, the first filler and the second shaft part block the suction force of the fan on the garbage due to the fact that no gap exists between the first filler and the second shaft part, the effect of entering and exiting the dust box by the garbage can be greatly reduced, and the cleaning efficiency is reduced.
In some embodiments, the first and second roller brushes are disposed back and forth along a direction of travel of the robotic cleaning device. At this time, a double-brush assembly structure with soft front and hard rear is formed, in order to ensure that garbage is missed from the rear, a plane where the lowest point of the outer contour of the second rolling brush is located is required to be lower than a plane where the lowest point of the outer contour of the first rolling brush is located, the interference quantity between the second brush and the ground is increased, and the garbage is protected from leaking from the lower surface of the second rolling brush.
In some embodiments, the second roller brush and the first roller brush are disposed back and forth along a direction of travel of the robotic cleaning device. At this time, a double-brush assembly structure with hard front and soft rear is formed, in order to ensure that garbage is missed from the rear, a plane where the lowest point of the outer contour of the first rolling brush is located is required to be lower than a plane where the lowest point of the outer contour of the second rolling brush is located, the interference quantity between the first brush piece and the ground is increased, and the garbage is protected from leaking from the lower surface of the first rolling brush.
According to the automatic cleaning equipment provided by the embodiment of the utility model, through the double-rolling-brush structure of the first rolling brush and the second rolling brush, the first filler in the first rolling brush is set to be an elastic member, and the second shaft component in the second rolling brush is set to be a rigid member, the automatic cleaning equipment can effectively clean the ground based on the soft rolling brush and the hard rolling brush, the trafficability of garbage between the first rolling brush and the second rolling brush is improved, the interference quantity between the soft rolling brush and the hard rolling brush and the ground is reasonably configured, and therefore the cleaning efficiency of the ground is improved as a whole.
The specific structure of the first rolling brush (also referred to as a soft brush or a cleaning brush) will be described in detail with reference to fig. 7-12, and the same structure and function have the same technical effects, and will not be described herein.
Fig. 7 is a perspective structural exploded view of an example of a cleaning brush provided according to the present utility model. Fig. 8 is a perspective view of an example of an end member of the cleaning brush of fig. 7. Fig. 9 is another angular perspective view of the end member of the cleaning brush of fig. 8.
Referring to fig. 7 to 9, a cleaning brush 100 is provided according to an embodiment of the present utility model. The cleaning brush 100 includes a shaft 110 including a shaft body 113, and first and second ends 111 and 112 at both sides of the shaft body 113, and a first end member 120 configured to be mounted to the first end 111, the first end member 120 having a first fitting structure 121 at a side remote from the shaft 110. Specifically, the first assembly structure 121 is a transmission structure, and the first assembly structure 121 is connected to a driving mechanism of the cleaning apparatus.
Specifically, the first end member 120 has at least one first lead-in portion 1221, the first end portion 111 has at least one first mating portion 1111, and the at least one first lead-in portion 1221 mates with the at least one first mating portion 1111 to form a guiding mating structure such that the first end member 120 can only be mounted to the first end portion 111 in one circumferential assembly, i.e., the first end member 120 and the shaft 110 have a single mounting direction when assembled.
The meaning of the circumferential assembly means herein is that the two assemblies are rotated 360 degrees relative to each other, and if there is N circumferential assembly means, it is assumed that the two assemblies have N circumferential assembly means, where N is 1 or more.
As shown in fig. 8, the first end member 120 includes a first guide sleeve 122, the first guide sleeve 122 is configured to accommodate the first end 111, and the at least one first introduction portion 1221 is disposed on an inner peripheral wall of the first guide sleeve 122 and is a protruding portion protruding inward from the inner peripheral wall of the first guide sleeve 122. The first end member 120 is mounted to the first end 111 on the drive side.
Specifically, the at least first lead-in 1221 extends helically in a circumferential direction of the first guide sleeve 122, in particular helically along the inner circumferential wall, in a direction away from the first fitting structure 121, such that the first lead-in 1221 has a rotational direction, e.g. a clockwise (or counter-clockwise) rotational direction about the axis z of the shaft 110.
In the present example, the first lead-in portion 1221 is a protruding portion protruding from the inner peripheral wall of the first guide sleeve 122, but is not limited thereto, and one of the first lead-in portion 1221 and the first engaging portion 1111 may be a protruding portion, and the other may be a recessed portion.
In the example of fig. 8, the number of the first introduction portions 1221 is two, and the sizes of the two first introduction portions 1221 are not the same. By providing the two first introduction portions with different sizes, it is possible to effectively ensure that the first end member 120 and the end portion on the driving side of the shaft have only a single mounting direction, thereby controlling the mounting direction of the components such as the blade of the cleaning brush to be unique.
In this example, the number of the first introducing portions 1221 is two, but the present utility model is not limited thereto, and in other examples, the number of the first introducing portions 1221 may be three or more, which is described as an alternative example only, and the present utility model is not limited thereto.
As can be seen from fig. 9, the outer periphery of the first end 111 of the shaft 110 is provided with a first engaging portion 1111 corresponding to the first introduction portion 1221. In this example, two first fitting portions 1111 are provided on the outer circumference of the first end portion 111, the two first fitting portions 1111 are respectively in one-to-one correspondence with the two first introduction portions 1221, the first fitting portions 1111 are groove portions recessed inward from the outer circumferential surface of the first end portion 111, and a guide fitting structure is formed by the first introduction portions 1221 and the first fitting portions 1111 so that the first end member 120 can be mounted to the first end portion 111 only in one circumferential fitting manner.
By adding two first introduction portions of different sizes to the inner peripheral wall of the first guide sleeve, introduction and installation can be performed more effectively, and the first end member can be installed to the first end portion only in one circumferential assembly manner, the ease of installation of the end member can be improved, and the stability of the installation structure can be improved.
Optionally, an indication portion 1223 (see fig. 8) is provided on the outer periphery of the first guide sleeve 122, and configured to indicate a position of the first lead-in portion 1221 on the outer periphery of the first guide sleeve 122, for indicating a rotational assembly direction of the first end member 120 mounted to the first end 111 of the shaft 110, so that the first lead-in portion 1221 is aligned with the first mating portion 1111.
As shown in fig. 8 to 10, the first guide sleeve 122 is provided with a first locking portion 1222, for example, a groove portion recessed inward from the outer peripheral surface of the first guide sleeve 122. Accordingly, a first locking mating portion 1112 is provided on the first end portion 111, and the first locking portion 1222 cooperates with the first locking mating portion 1112 such that the first end member 120 is locked to the first end portion 111.
Referring to fig. 9 and 10, the first end member 120 further includes a first guide shaft 123, the first guide shaft 123 extends along an axis of the first guide sleeve 122, a first guide hole 1113 is provided on an end surface of the first end 111 remote from the second end 112, and the first guide hole 1113 is coaxial with the shaft 110 and configured to accommodate the first guide shaft 123.
As shown in fig. 9 and 10, the end surface of the first assembly structure 121 away from the shaft has a regular polygon, and the number of sides of the regular polygon is a divisor of the number of brushes. In other words, the number of sides of the regular polygon of the outer end surface of the first end member and the number of groups of brushes of the automatic cleaning apparatus have a correspondence relationship. For example, the number N of sides of the regular polygon is a divisor of the number of groups (for example, 4 sides, 8 groups of blades; for example, 4 sides, 4 groups of blades), thereby ensuring that the direction of the blades and the like in the brush member of the cleaning brush is uniform after the cleaning brush is mounted on the main unit of the automatic cleaning device according to the N directions.
In the present embodiment, the sides of the regular polygon are N straight sides, but the present invention is not limited thereto, and in other embodiments, the sides may be modified, for example, curved sides, or a combination of straight sides and curved sides. Further, in other examples, the regular polygon shape may adaptively change according to the number of brushes.
In the example of fig. 7, the cleaning brush 100 further includes a brush member 130 coaxially disposed with the shaft 110, the brush member 130 including a cylindrical member 131 fitted over the outer circumference of the shaft, and a plurality of brushes 132. The plurality of brushes 132 extend from the outer surface of the cylindrical member in a direction away from the cylindrical member 131, and the plurality of brushes 132 are uniformly arranged in the circumferential direction of the cylindrical member.
In particular the brush 131 comprises a first brush. For example, the first brush member is V-shaped and includes five sets of first brush members.
In other examples, the brush may further include a second brush, a third brush, or the like, the second brush and the third brush having different shapes, lengths, or the like than the first brush. In addition, the brush structures of the different sets are substantially identical, and each set may include one or more blades, and when multiple blades are included, the structures of the multiple blades tend not to be identical.
Specifically, a flexible filler (not shown) is filled between the brush member 130 and the shaft 110, and the flexible filler covers the outer circumference of the shaft body, exposing the first end and the second end.
Further, the first end member 120 further comprises a first blocking structure 125 arranged between said first fitting structure 121 and said first guide sleeve 122 for preventing the windings from being over-extended away from said brush member and for preventing the windings from being over-extended away from said cleaning brush. The first blocking structure 125 is, for example, at least one blocking ring, in this example, two blocking rings. As shown in fig. 8, the first blocking structure 125 includes a first wall, a recess, and a second wall from the outside to the inside in the axial direction of the cleaning brush, wherein the thickness of the first wall is greater than the thickness of the second wall. By arranging the blocking structure, the winding object such as garbage is wound on the blocking structure of the first end component, the winding object is effectively prevented from being wound on the shaft rod, and the winding object can be directly taken down along with the disassembly of the end component when the end component is disassembled.
The guide matching structure is formed by the first guide-in part in the first guide sleeve of the first end part component and the end part of the shaft rod at the driving side, and the locking matching structure is formed by the first locking part on the first guide sleeve and the first locking matching part at the end part of the shaft rod in a matching way, and the guide matching structure and the locking matching structure are matched in an assisted way, so that a more effective mounting structure can be realized, the mounting structure of the end part component and the shaft rod can be further optimized, and the integral structure of the cleaning brush can be further optimized.
Fig. 11 is an exploded view of another angle of the cleaning brush of fig. 7, and fig. 12 is an exploded view of a second end member and an angle of a shaft of the cleaning brush of fig. 7.
As shown in fig. 11 and 12, the cleaning brush 100 further includes a second end member 140. The second end member 140 is positioned on the driven side and is mounted to the second end 112 of the shaft 110. The side of the second end member 140 remote from the shaft 110 has a second mounting structure 141 (in particular a bearing structure), the second mounting structure 141 being rotatable relative to the shaft, the second mounting structure 141 being rotatably connected to other structures of the cleaning device (e.g. the body, etc.).
As shown in fig. 11 and 12, the second end member 140 has at least one second lead-in portion 1421, the second end 112 has at least one second mating portion 1121, and the at least one second lead-in portion 1421 and the at least one second mating portion mate 1121 form a guide mating structure such that the second end member 140 can be mounted to the second end in a variety of circumferential assemblies.
Further, the second introduction portion 1421 is spirally extended in a circumferential direction of the second guide sleeve 142, particularly, spirally extended spiral along the inner circumferential wall in a direction away from the second fitting structure 141, so that the second introduction portion 1421 has a rotation direction, for example, a rotation direction of clockwise (or counterclockwise) rotation about the axis z of the shaft 110, thereby forming a second introduction direction. In this example, the second direction of introduction is the same as the first direction of introduction.
In this example, the first introduction direction and the second introduction direction are the same, but the present utility model is not limited thereto, and in other examples, the rotation direction of the first introduction portion may be, for example, a non-spiral type or a linear type. Further, in other examples, the second direction of introduction may also be different from the first direction of introduction. The foregoing is illustrative only and is not to be construed as limiting the utility model.
As shown in fig. 12, the at least one second lead-in 1421 comprises two second lead-ins 1421, the two second lead-ins 1421 being identical in shape and size, such that the second end member can be mounted to the second end 112 in two circumferential assemblies.
Preferably, in the case where the introduction directions of the first introduction portions 1221 and the second introduction portions 1421 are the same, the two first introduction portions 1221 are different in size (corresponding to the difference in size of the first fitting portion 1111 and the second fitting portion 1121), the two second introduction portions 1421 are the same in size, and the second introduction portion 1421 is between the sizes of the two first introduction portions 1221.
The sizes of the two second guide parts of the driven end are between the sizes of the two first guide parts of the driving side, so that the free installation of a plurality of angles of the second end parts can be ensured, the reverse installation of the end parts on two sides can be avoided, and the correct orientation of the parts such as blades after the cleaning brush is installed can be effectively ensured.
In addition, the number of the second introduction portions may be three or more in other examples. The foregoing is illustrative only and is not to be construed as limiting the utility model. Furthermore, it is preferred for the first end member and the second end member that two first lead-ins of different dimensions are provided on the drive side, since there is a requirement for an installation angle on the drive side, whereas the second end member on the driven side does not require a different-sized design, since the second mounting structure (in particular the bearing structure) on the driven side is freely rotatable relative to the shaft, which bearing structure, when mounted to the machine body of the automatic cleaning device, allows the rest of the cleaning brush to freely rotate relative to the bearing structure, and the driven side does not have a strong requirement for an assembly angle, so that in other examples the dimensions of the second lead-ins may also be identical.
By forming the guide fitting structure by the first and second introduction portions 1221 and 1421 and the first and second fitting portions 1111 and 1121, a more effective guide fitting structure can be realized. By the arrangement of the two first lead-in portions 1221 having different sizes, the second lead-in portion and the first lead-in portion have different sizes, so that the first end member can be mounted to the first end portion only in one circumferential fitting manner, and so that the second end member can be mounted to the second end portion in a plurality of circumferential fitting manners, the mounting angles of the first end member and the second end member with the shaft can be accurately determined, and a more effective mounting structure can be realized.
Further, the second locking portion 1422 is provided on the outer periphery of the second guide sleeve 142 of the second end member 140, for example, a groove portion recessed inward from the outer periphery of the second guide sleeve 142, and the second locking portion 1422 may be a through hole penetrating the second guide sleeve 142. Accordingly, the second end 112 is provided with a first locking mating part 1123, and the second locking part 1422 is mated with the second locking mating part 1123 such that the second end member 140 is locked to the second end 112 to form a locking mating structure.
As shown in fig. 12, the second end member 140 further includes a second guide shaft 144, where the second guide shaft 144 extends along an axis of the second guide sleeve 142, and a second guide hole (not shown) is disposed on an end surface of the second end 112 remote from the first end 111, and the second guide hole is coaxial with the shaft 110 and configured to receive the second guide shaft 144.
Further, the second end member 140 further comprises a second blocking structure 145, wherein the second blocking structure 145 is disposed on a side of the second guide sleeve 142 away from the shaft 110.
Specifically, the blocking structure 145 has an outer diameter greater than an outer diameter of the second guide sleeve 142. By arranging the blocking structure on the second end member, the winding such as garbage is wound on the blocking structure of the second end member, so that the winding is effectively prevented from winding to the shaft rod, and the winding can be directly taken down along with the disassembly of the end cover member when the end member is disassembled.
Optionally, the second guide sleeve 142 may be further provided with an indication portion 1423 configured to indicate a position of the second introduction portion 1421 on an outer circumference of the second guide sleeve 142 for indicating a rotational assembly direction of the second end member 140 to the shaft 110 and the second end 112 so that the second introduction portion is assembled in alignment with the second fitting portion.
Further, the second fitting structure 141 of the second end member 140 is configured in a polygonal shape corresponding to the number of brushes. In this example, the polygonal shape of the outer end surface of the second fitting structure 141 is a pentagon formed by combining straight lines and curved lines.
Preferably, the regular polygon shape of the outer end surface of the first end member 120 is different from the polygon shape of the outer end surface of the second fitting structure 141, so that the outer end surface shapes of the first end member and the second end member are different, the two ends can be distinguished more easily, and convenience of installation can be improved.
The cleaning brush of the utility model ensures that the drive end has a relatively fixed mounting direction by arranging the lead-in member of the end member with a unique circumferential assembly, which contributes to the controllable mounting angle of the roller brush, which is particularly advantageous in some situations where there is a certain preset requirement for the direction or alignment of the subcomponents of the roller brush, in particular the blades, for example in those situations where two present roller brushes are used to form a double brush system and there is a certain alignment requirement for their respective blades.
According to the cleaning brush, the guide matching structure is formed by the guide part of the inner wall of the guide sleeve of the end part component and the end part of the shaft rod, and the locking part of the periphery of the guide sleeve and the end part of the shaft rod form the locking matching structure, the guide matching structure and the locking matching structure are matched in an assisted manner, so that the guide and installation can be more effectively carried out, the more effective guide matching structure can be realized, the more effective foolproof installation structure can be realized, the installation simplicity and the installation structure stability of the end part component can be improved, and the installation structure of the end part component and the shaft rod can be optimized, so that the integral structure of the cleaning brush is optimized.
Furthermore, by the arrangement of the two first introduction portions having different sizes, the arrangement of the second introduction portion having different sizes from the first introduction portion makes it possible to mount the first end member to the first end portion only in one circumferential fitting manner, and makes it possible to mount the second end member to the second end portion in a plurality of circumferential fitting manners, the mounting angles of the first end member and the second end member to the shaft can be accurately determined, and a more effective mounting structure can be realized.
In addition, by providing the indication portions on the outer circumferences of the first guide sleeve and the second guide sleeve to indicate the rotational fitting directions of the first end portion member and the second end portion member to be attached to the first end portion and the second end portion of the shaft, the alignment fitting of the first introduction portion and the first fitting portion can be effectively ensured, and the alignment fitting of the second introduction portion and the second fitting portion can be effectively ensured.
Further, by the divisor of the number of sides of the regular polygon of the outer end surface of the first end member and the number of groups of the brush members of the automatic cleaning apparatus, it is possible to ensure that the orientations of the members such as the blades in the brush members of the cleaning brush are uniform after the cleaning brush is mounted to the main body of the automatic cleaning apparatus in the N directions.
In addition, through setting up the structure that blocks at the end component, make the direct winding of winding in the structure that blocks of end component, can effectively avoid winding to the axostylus axostyle.
The specific structure of the second rolling brush (also referred to as a hard brush or a cleaning brush) will be described in detail with reference to fig. 13-21, and the same structure and function have the same technical effects, and will not be described herein.

In other examples, the mating portion may be a groove, and the guiding portion may be a protrusion. As for the number of the fitting portions, in other examples, three, four, six or more may be also used as long as the same number of the guide portions and the number of the fitting portions are satisfied, which is described as an alternative example only and is not to be construed as limiting the present utility model.

In some embodiments, the blocking structure 225 has an outer diameter greater than the inner and outer diameters of the receiving space, and the brush member includes a cylindrical member having a diameter smaller than the blocking structure. One end of the brush adjacent to the shaft is within the axial projection of the blocking structure 225, the first brush has a first thinned portion substantially within the axial projection of the blocking structure, and the second brush has a second thinned portion located within and outside the axial projection of the blocking structure.
By arranging the blocking structure on the end member, the winding is directly wound on the blocking structure of the end member, and winding of the winding to the shaft rod can be effectively avoided.
In another example, as in the cleaning brush 200 shown in fig. 19, the end member 2200 includes a first side end member 2200' and a second side end member 2200″ that are matingly mounted with the mating members 213 of the first end 211 and the second end 212, respectively, of the shaft 210, the shaft 210 is a rigid component, the brush member 230 is directly sleeved on the shaft 210, and the cleaning brush 200 is, for example, a hard brush.

For example, the number of the first guide portions 2221 'of the first side end member 2200' is five, and the number of the second guide portions 2221″ of the second side end member 2200″ is two.
As shown in fig. 19 and 20, a first side end member 2200 '(i.e., an end member 2200 on the driving side, a left side end as viewed in fig. 20) is mounted to the first end 211 of the shaft 210, the first side end member 2200' including a transmission structure 221', the transmission structure 221' being located further to the outside than the first blocking structure 225', the end surface shape of the transmission structure 221' being a polygonal shape, such as a regular polygon.

It should be noted that, in this example, the brush 232 includes at least one size of the first brush, for example, five groups of brushes, each group of brushes includes two sizes of the first brush, for example, the first brush is V-shaped and spiral-shaped. Since the brush member 230 in this example is substantially the same as the brush member 230 in the example of fig. 13, the description of the same portions is omitted.
Specifically, the number of first guide portions 2221 'of the first side end member 2200' is a divisor of the number of brushes 232. For example, the number of the first guide portions 2221' is five, the brushes 232 are multiples of five, such as five groups, ten groups, etc., wherein each group includes two brushes or more brushes.
By setting the number of the first guide portions 2221' to be a divisor of the number of the groups of the brushes 232, when the rolling brushes are mounted in the rolling brush frame, the brushes 232 have a specific mounting angle so as to facilitate matching interference of the brushes corresponding to the two rolling brushes.

Alternatively, the number of the first guide portions 2221 'of the first side end member 2200' is an odd number, and the number of the second guide portions 2221″ of the second side end member 2200″ is an even number. Preferably, the number of the first guide portions 2221 'of the first side end member 2200' and the number of the second guide portions 2221 "of the second side end member 2200" are not a divisor of each other, so as to ensure that the side end member with the smaller number of the guide portions cannot be assembled to the mating piece corresponding to the side end member with the larger number of the guide portions, thereby ensuring that any one side end member cannot be assembled in a wrong way, and realizing the maximum fool-proofing.
As shown in fig. 20 and 21, the second end 212 of the shaft 210 includes a second mating member 213 "that mates with a second guide portion 2221" of the second guide bar 222", the number of the second guide portions 2221" being two, and the second guide portion 2221 "being an end portion of the second guide bar 222" away from the bearing structure 221 "where a groove is etched from an outer circumferential surface of the second guide bar 222" to form a protrusion.

As shown in fig. 20 and 21, the outer peripheral surface of the extension portion 2132 "of the second mating member 213" is provided with a plurality of ribs 21321 "uniformly distributed, so that the outer peripheral surface of the extension portion 2132" forms a concave-convex surface for forming a corresponding mating structure with the interior of the shaft 210 (i.e. the shape of the interior of the shaft), so as to increase the contact surface between the second mating member 213 "and the interior of the shaft 210, further facilitate the bonding of the second mating member 213" in the accommodating space of the shaft 210, increase the bonding strength of the bonding structure between the second mating member 213 "and the shaft 210, and make the installation more stable.
Further, an end portion of the second engaging piece 213″ near the shaft center side is provided with a fastening portion 21322", and the fastening portion 21322″ is closer to the shaft center side than the protruding rib 21321". The engaging portion 21322″ is, for example, a claw portion, and the engaging portion 21322″ and the engaging piece 2231 (i.e., an annular groove portion) of the guide shaft 223 of the second side end member 2200″ form a snap-fit structure.
In the example of fig. 19, the first side end member 2200 'includes an assembly structure (specifically, a transmission structure 221'), a first guide shaft 223', one end of the first guide shaft 223' is sleeved on the first guide rod 222', the other end of the first guide shaft 223' is sleeved on a first guide hole of the first end 211, and the first guide hole is coaxially opened on an end surface of the first end 211.

Optionally, the first lateral end member 2200 'is provided with a blocking structure 225', in particular between the mounting structure (in particular the transmission structure 221 ') and the first guide bar 222'. The second lateral end member 2200 "is provided with a blocking structure 225", in particular between said mounting structure (in particular the bearing structure 221 ") and said second guide bar 222". The blocking structures of both side end members serve to prevent the windings from being excessively extended away from the brush member 230.

Alternative embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.
The rolling brush provided in the embodiment of the utility model can be applied to various automatic cleaning devices, and as an example, a schematic structural diagram of an automatic cleaning device is shown in fig. 1, but the device to which the rolling brush provided in the embodiment is applicable should not be limited thereto.
Referring to fig. 22 and 23, fig. 22 is a schematic structural view of a rolling brush according to some embodiments of the present utility model, and fig. 23 is a schematic sectional structural view of the rolling brush in fig. 22. As shown, in some embodiments, the roll brush 100 includes a shaft 10 and a brush member 20, wherein the brush member 20 is disposed on the shaft 10.
The shaft 10 may be a rod-like structure, such as an elongated cylindrical structure. The two ends of the rod-like structure may be detachably mounted to the bottom of the apparatus body of the automatic cleaning apparatus directly or through a connection member. In some embodiments, the shaft 10 is detachably mounted to the bottom of the device body in an elongated groove structure extending in the transverse axis Y direction, along with the brush member 20 provided on the shaft 10.
The axis of the shaft 10 may be regarded as a rotation axis of the roll brush 100, and when the roll brush 100 is mounted to the apparatus body of the automatic cleaning apparatus, a driving system on the apparatus body can drive the shaft 10 to rotate, and the rotation direction may be clockwise or counterclockwise. When the shaft 10 rotates, other components disposed on the shaft 10, such as the brush member 20, are driven to rotate together for cleaning purposes.
The brush member 20 is disposed on the shaft 10, and in particular in some embodiments, the brush member 20 is removably disposed on the shaft 10 to facilitate routine cleaning maintenance of the brush member 20.
The brush member 20 may further comprise a tubular member 23 and at least one first brush 21.
The cylindrical member 23 is configured to fit over the shaft 10 such that the cylindrical member 23 is coaxial with the shaft 10. The cylindrical member 23 may have a long cylindrical structure, and the length of the cylindrical member 23 is substantially the same as the length of the shaft 10. The cylindrical member 23 is tightly sleeved on the shaft 10, and the inner diameter of the cylindrical member 23 is substantially equal to or slightly smaller than the diameter of the shaft 10, so that the shaft 10 and the cylindrical member 23 do not move relatively during rotation. The tubular member 23 may be a flexible member or a rigid member.
The first brush 21 extends from the outer surface of the tubular member 23 in a direction away from the tubular member 23. In some embodiments, the first brush 21 is tilted in a first rotational direction in the circumferential direction of the tubular member 23, and fig. 24 shows an angle α between the first brush 21 and a tangent to the tubular member 23, where α is less than 90 °, for example in some embodiments, the value of α ranges from 45 ° to 85 °. By arranging the first brush 21 to tilt in the circumferential direction of the cylindrical member 23 along the first rotation direction, a certain included angle is formed between the first brush 21 and the cleaning surface (such as the ground), so that the garbage on the cleaning surface is more easily taken away in the cleaning process, and the cleaning capability is improved.
In some embodiments, the roller brush 100 further includes end caps 30 provided at both ends of the shaft 10, and the roller brush 100 is mounted into an elongated groove structure of the bottom of the main body of the automatic cleaning apparatus by mounting members of the end caps 30 on the side remote from the shaft 10.
In some embodiments, the first brush 21 extends from one end of the tubular member 23 to the other end of the tubular member 23. In some embodiments, the first brush 21 extends at an angle to the axis of the shaft 10. For example, the first brush 21 may be spirally disposed on the outer surface of the cylindrical member 23, so that the first brush 21 has more contact points with the cleaning surface, so that the first brush 21 can be in more sufficient contact with the cleaning surface, thereby facilitating the removal of the garbage on the cleaning surface and improving the cleaning capability.
In some embodiments, the end of the first brush 21 adjacent to the tubular member 23 is provided with a one-way blocking structure. The unidirectional blocking structure may make the first brush 21 be easily deformed in the reverse direction of the first rotation direction, but not easily deformed in the first rotation direction, i.e., make the deformation of the first brush 21 when rotated in the first rotation direction smaller than the deformation when rotated in the reverse direction of the first rotation direction. The first rotation direction is generally the rotation direction of the brush when the cleaning device performs a cleaning operation, and the opposite direction of the first rotation direction is the rotation direction of the brush when the cleaning device performs a dust collecting operation. The first brush piece 21 can provide powerful cleaning function when the cleaning device is cleaned normally by arranging the unidirectional blocking structure, and is not easy to topple and deform along the first rotation direction, and the first brush piece 21 is easy to deform along the reverse direction of the first rotation direction when dust is collected, so that large-particle garbage is prevented from being clamped during dust collection.
Referring to fig. 24, in some embodiments, the one-way check structure includes a support member 2111, the support member 2111 being capable of blocking deformation of the first brush 21 in a first rotational direction. Specifically, the support member 2111 is provided on the first rotational direction side of the end of the first brush 21 that is close to the tubular member 23.
As shown in fig. 24, in some embodiments, the first brush 21 has a first end portion for contacting the surface to be cleaned when the automatic cleaning apparatus is in operation, and a second end portion having a thickness smaller than that of the first end portion, for example, the second end portion has a first thinned portion with respect to the first end portion, the first thinned portion being disposed in a direction of arrangement of the second end portion substantially in the same direction as an inclined direction of the first brush with respect to a radial direction of the first roller brush.
In some embodiments, as will be appreciated with reference to fig. 24, the second brush also has a first end for contacting a surface to be cleaned when the automatic cleaning apparatus is in operation and a second end having a thickness less than that of the first end of the second brush, e.g., the second end of the second brush has a second thinned portion with respect to the first end of the second brush, the second thinned portion being disposed in a direction of arrangement of the second end of the second brush substantially opposite to a direction of inclination of the second brush with respect to the radial direction of the first roller brush.
In some embodiments, the second thinned portion is disposed in a direction opposite to the direction in which the first thinned portion is disposed at the second end of the first brush.
In some embodiments, the thickness of the first brush 21 at the end near the tubular member 23 is less than a preset threshold such that the first brush 21 has a tendency to deform in both the first rotational direction and the reverse direction of the first rotational direction. Specifically, in some embodiments, a slit 216 is provided between the support component 2111 and the end of the first brush 21 that is proximate to the tubular member 23, such that the thickness of the first brush 21 at the end proximate to the tubular member 23 is less than a preset threshold. The support member 2111 supports the end of the first brush 21 near the tubular member when the first brush 21 has a tendency to deform in the first rotational direction, and the slit width of the slit 216 becomes smaller when the end of the first brush 21 near the tubular member 23 is far from the support member 2111 when the first brush 21 has a tendency to deform in the opposite direction of the first rotational direction. By providing the slit 216, a certain gap exists between the first brush 21 and the supporting member 2111, so that the first brush 21 can have a certain degree of freedom in the first rotation direction, and can be appropriately deformed to adapt to different cleaning surfaces. In an actual cleaning operation, the slit width of the slit 216 may be adjusted according to the cleaning surface, so that the degree of deformation of the first brush 21 in the first rotation direction may be changed to some extent to accommodate different cleaning surfaces.
In some embodiments, the first brush 21 has an end proximate to the tubular member 23, and the support feature 2111 has a bevel facing the end. Further, the inclination angle β of the inclined surface with respect to the circumference Xiang Qiemian of the cylindrical member 23 is smaller than the inclination angle α of the first brush 21 with respect to the circumference Xiang Qiemian of the cylindrical member 23, and the specific angles of the two may be adjusted according to the actual situation, so that the first brush 21 may also have a certain degree of freedom in the first rotation direction, and may be appropriately deformed to adapt to different cleaning surfaces. In an actual cleaning operation, the inclination angles α, β may be adjusted according to the cleaning surface, so that the degree of deformation of the first brush 21 in the first rotational direction is changed to some extent to accommodate different cleaning surfaces.
The support part 2111 extends along an end of the first brush 21 near the cylindrical member 23. In some embodiments, the support member 2111 is a continuous structure, i.e., the support member 2111 extends continuously along the end of the first brush 21 proximate the tubular member 23, extending along one end of the tubular member 23 to the other end of the tubular member 23. It will be appreciated that in other embodiments, referring to fig. 25, the support members 2111 are of an intermittent configuration, i.e., the support members 2111 are disposed discretely near the ends of the tubular member 23. When the support member 2111 has an intermittent structure, a material can be saved, the entire weight of the first brush 21 can be reduced, and the intermittent structure of the support member 2111 can also reduce the remaining of the trash due to the gap between the first brush 21 and the support member 2111.
Referring to fig. 26, in some embodiments, the one-way check structure includes a slit, for example, a slit 215 is provided at an end of the first rotation direction side of the first brush 21 near the cylindrical member 23. The slits 215 are closed to prevent the first brush 21 from being deformed in the first rotational direction when the first brush 21 has a tendency to be deformed in the first rotational direction, and the slits 215 are enlarged to deform the first brush 21 in the opposite direction of the first rotational direction when the first brush 21 has a tendency to be deformed in the opposite direction of the first rotational direction. By providing the slit 215 on the first brush 21, the deformation parameter of the first brush 21 in the reverse direction of the first rotation direction can be changed, so that the first brush 21 is easy to deform in the reverse direction of the first rotation direction and is not easy to deform in the first rotation direction. And the process of arranging the slit 215 on the first brush piece 21 is simple, and the popularization and the application are convenient.
Further, the angle of inclination of the slit 215 with respect to the circumference Xiang Qiemian of the tubular member 23 is smaller than the angle of inclination of the first brush 21 with respect to the circumference Xiang Qiemian of the tubular member 23. By providing different inclination angles, the first brush member 21 can also have a certain degree of freedom in the first rotation direction, and can be appropriately deformed to accommodate different cleaning surfaces. In an actual cleaning operation, the inclination angle α and the inclination angle of the slit 215 with respect to the circumference Xiang Qiemian of the tubular member 23 may be adjusted according to the cleaning surface, so that the degree of deformation of the first brush 21 in the first rotational direction may be changed to some extent to accommodate different cleaning surfaces.
In some embodiments, the surface of the first brush 21 is provided with bumps 213. In some embodiments, there may be a plurality of protruding points 213, the plurality of protruding points 213 being arranged along the extending direction of the first brush 21, and the protruding points 213 being located away from the cylindrical member 23, close to the cleaning surface. The contact area between the first brush 21 and the garbage can be increased by arranging the convex points 213, the capacity of the first brush 21 for taking the garbage away from the cleaning surface is improved, and the cleaning effect of the first brush 21 is enhanced.
It is understood that the number of the first brushes 21 may be plural, and the plurality of the first brushes 21 are uniformly distributed in the circumferential direction of the cylindrical member 23. The plurality of first brushes 21 may cooperate to increase the contact area between the brushes and the cleaning surface and to increase the cleaning efficiency when performing the cleaning operation.
In some embodiments, the brush member 20 further includes a second brush 22. The second brush 22 extends from the outer surface of the cylindrical member 23 in a direction away from the cylindrical member 23. In some embodiments, the second brush 22 is inclined in the first rotation direction along the circumference of the cylindrical member 23, and the value of the tilting angle may be 45 ° to 85 °. By arranging the second brush 22 to tilt along the first rotation direction in the circumferential direction of the cylindrical member 23, a certain included angle is formed between the second brush 22 and the cleaning surface, so that the garbage on the cleaning surface is more easily taken away in the cleaning process, and the cleaning capability is improved.
In some embodiments, the second brush 22 extends from one end of the tubular member 23 to the other end of the tubular member 23. In some embodiments, the second brush member 22 extends at an angle to the axis of the shaft 10. For example, the second brush 22 may be spirally disposed on the outer surface of the cylindrical member 23, so that the second brush 22 has more contact points with the cleaning surface, so that the second brush 22 can be more fully contacted with the cleaning surface, thereby facilitating the removal of the garbage on the cleaning surface and improving the cleaning capability.
It is understood that the number of the second brushes 22 may be plural, and the plurality of the second brushes 22 are uniformly distributed in the circumferential direction of the cylindrical member 23. Further, the first brushes 21 and the second brushes 22 are alternately and uniformly arranged in the circumferential direction of the cylindrical member 23. For example, the brush member 20 of the roll brush 100 includes 10 brushes, 5 of which are first brushes 21 and 5 of which are second brushes 22, the first brushes 21 and the second brushes 22 being alternately and uniformly arranged in the circumferential direction of the cylindrical member 23.
In some embodiments, the extension of the second brush 22 away from the tubular member 23 is greater than the extension of the first brush 21 away from the tubular member 23, and the thickness of the brush body of the second brush 22 is less than the thickness of the brush body of the first brush 21. That is, the first brush 21 is relatively short and thick, and the second brush 22 is long and thin. The first brush piece 21 can provide strong cleaning force when treating garbage with a little bigger size such as garbage such as shells and particles, the first brush piece 21 is not contacted with a cleaning surface when the working condition of a flat and hard cleaning surface such as ceramic tiles and wood floors is met, the second brush piece 22 can be contacted with the ground when the working condition of the flat and hard cleaning surface such as ceramic tiles and wood floors is met, dust, hair and the like are beaten and rolled up, then the dust box is sucked, the contact force of the second brush piece 22 with the ground is small, the daily cleaning noise is low, and when the working condition of carpet cleaning with a certain thickness is met, the first brush piece 21 and the second brush piece 22 are contacted with the surface of the carpet, and the relatively thick first brush piece 21 plays a key role in beating and stripping dust and hair hidden in the carpet, so that the cleaning effect is improved.
In some embodiments, the thickness of the end of the second brush 22 distal from the tubular member 23 is greater than the thickness of the end of the second brush 22 proximal to the tubular member 23. Thereby, the second brush 22 has better deformation parameters at the end close to the tubular member 23, so that the second brush 22 can be correspondingly deformed according to different cleaning operations.
In some embodiments, the tubular member 23 is incompressible after the tubular member 23 is over the shaft 10. That is, the roll brush 100 is a hard brush structure. The shaft 10 is, for example, a hard rod, and the tubular member 23 is incompressible after the tubular member 23 is fitted over the hard shaft 10. That is, the shaft is at least partially incompressible to the surface of the brush member support, e.g., the shaft is entirely incompressible to the surface of the brush member support.
In some embodiments, the robotic cleaning device includes a first roller brush and a second roller brush, the first shaft member having a support surface that contact-supports the first brush member, at least a portion of the support surface of the first shaft member being incompressible, e.g., all of the support surface of the first shaft member being incompressible.
In some embodiments, the second roller brush includes a second shaft component having a support surface that contacts and supports the second brush member, and a second brush member, at least a portion of the support surface of the second shaft component being incompressible, e.g., all of the support surface of the second shaft component being incompressible.
In some embodiments, the support surface at the axial end of the first shaft component is compressible, the remainder being incompressible.
In some embodiments, the support surface at the axial end of the second shaft member is compressible and the remainder is incompressible.
In some embodiments, the support surface at an axially intermediate position of the first shaft member is compressible, the remainder being incompressible.
In some embodiments, the support surface at an axially intermediate position of the second shaft member is compressible, the remainder being incompressible.
In some embodiments, the compressible portion of the support surface of the first shaft member is smaller in area than the incompressible portion.
In some embodiments, the compressible portion of the support surface of the second shaft member is smaller in area than the incompressible portion.
In some embodiments, the support surface of the first shaft member over at least a portion of its axial length includes both a compressible portion and an incompressible portion in the circumferential direction.
In some embodiments, the support surface of the second shaft member is at least partially axially long, with both compressible and incompressible portions being present in the circumferential direction.
In some embodiments, the length of the support surface of the first shaft component in the axial direction of the first shaft component is less than the first brush member.
In some embodiments, the support surface of the second shaft part has a length in the axial direction of the second shaft part that is smaller than the second brush member. In some embodiments where the robotic cleaning device has two roller brushes at the same time, where the cylindrical member of one roller brush is compressible and the cylindrical member of the other roller brush is incompressible, a one-way blocking structure may be provided on at least one of the two roller brushes as desired, and in some embodiments the structure may be provided for only the roller brush where the cylindrical member is incompressible, as the compressible roller brush may be somewhat less desirable for solving the corresponding problem. Of course, the blocking structure may also be selected for use with a compressible roll brush depending on the particular material, particularly when the material is relatively hard or compressible.
According to the rolling brush and the automatic cleaning equipment, the unidirectional blocking structure is arranged at the end part of the first brush close to the cylindrical component, so that the first brush is easy to deform in the reverse direction of the first rotating direction and is not easy to deform in the first rotating direction, the first brush can provide a powerful cleaning effect when the automatic cleaning equipment is used for cleaning normally, the first brush is not easy to topple and deform along the first rotating direction, and the first brush is easy to deform along the reverse direction of the first rotating direction when dust is collected, so that large-particle garbage is prevented from being clamped during dust collection, the cleaning efficiency is improved, and better user experience is obtained.
In the related art, an automatic cleaning device, such as a sweeping robot, has a double-rolling brush type, and for the double-rolling brush type, the front rolling brush and the rear rolling brush can enhance the cleaning capability of the automatic cleaning device, but the blades of the front rolling brush and the rear rolling brush do not interfere with each other, and a gap with a preset size is always reserved between the two rolling brushes so as to suck garbage on an operation surface into an air duct. The dust collection effect of the automatic cleaning equipment needs to be further improved.
The utility model provides automatic cleaning equipment which comprises a moving platform and a cleaning module, wherein the moving platform is configured to automatically move on an operation surface, the cleaning module is assembled on the moving platform and is configured to clean the operation surface, the cleaning module comprises a first rolling brush and a second rolling brush, the first rolling brush is arranged along a first direction perpendicular to the axis of the moving platform, the first rolling brush comprises a first long brush piece, the second rolling brush is arranged side by side with the first rolling brush, the second rolling brush comprises a second long brush piece, and an air duct is arranged on one side, away from the operation surface, of the first rolling brush and the second rolling brush and is configured to guide dust to be accommodated, and when the automatic cleaning equipment performs cleaning operation, the first long brush piece and the second long brush piece mutually interfere to form an interference area, the interference area is configured to dynamically move along a preset direction, and an air duct inlet of the air duct is arranged at the downstream of the preset direction.
When the automatic cleaning equipment executes cleaning operation, the first long brush piece of the first rolling brush and the second long brush piece of the second rolling brush of the cleaning module mutually interfere to form an interference area, so that an air inlet passage between the two rolling brushes is at least partially closed, the opening size of the air inlet passage is reduced, the dust collection pressure is increased, and a better dust collection effect is realized. The interference area is configured to dynamically move along a preset direction, so that the area with the largest suction force in the air inlet passage between the two rolling brushes also dynamically moves along the preset direction, and dust at all positions of the operation surface cleaned by the rolling brushes can be sucked into the air duct in sequence by larger suction force and then enter the dust box. The air duct inlet of the air duct is arranged at the downstream of the preset direction, so that dust can conveniently enter the dust box through the air duct.
Alternative embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.
Fig. 27 is a schematic structural diagram of another view of a cleaning module according to some embodiments of the present utility model, fig. 28 is a schematic structural diagram of a cross section of a cleaning module according to some embodiments of the present utility model, and fig. 29 is a schematic structural diagram of a first rolling brush and a second rolling brush according to some embodiments of the present utility model. Some embodiments of the present utility model provide a robotic cleaning device that includes a mobile platform 1000 and a cleaning module 5000. The mobile platform 1000 is configured to automatically move on an operation surface, and the cleaning module 5000 is mounted on the mobile platform 1000 and is configured to perform cleaning operation on the operation surface.
As shown in fig. 27 to 29, the cleaning module 5000 includes a first rolling brush 100, a second rolling brush 200, and an air duct 5400. The first and second roller brushes 100 and 200 constitute the aforementioned roller brush 5300.
The first roll brush 100, for example a front brush, is arranged in a first direction perpendicular to the axis of the moving platform, for example the front-rear axis X, and the first direction, for example the direction in which the transverse axis Y extends. The first rolling brush 100 includes a first long brush member 131, i.e., a first long blade, which is relatively long and thin, and can contact with the ground to flap up dust, hair, etc. to be cleaned and then be sucked into a dust box when treating a flat and hard cleaning surface of a tile, a wooden floor, etc. The contact force between the long blade and the ground is small, cleaning is daily with low noise.
The second rolling brush 200, for example, a rear brush, is disposed along a first direction perpendicular to the axis of the moving platform, and the second rolling brush 200 includes a second long brush member 231, i.e., a second long blade.
The air duct 5400 is disposed at a side of the first and second roller brushes 100 and 200 away from the operation surface, and configured to guide dust to be accommodated, for example, to a dust box.
When the automatic cleaning apparatus performs a cleaning operation, the first and second rolling brushes 100 and 200 roll in opposite directions to perform a cleaning operation. Specifically, the first rolling brush 100 rotates in a first rotation direction R1, the first rotation direction R1 is, for example, a counterclockwise direction, and the second rolling brush 200 rotates in a second rotation direction R2, the second rotation direction R2 is, for example, a clockwise direction. The first long brush member 131 of the first rolling brush 100 and the second long brush member 231 of the second rolling brush 200 may contact the ground to flap up the dust, hair, etc. to be cleaned.
When the automatic cleaning apparatus performs a cleaning operation, the first long brush member 131 of the first rolling brush 100 and the second long brush member 231 of the second rolling brush 200 interfere with each other to form an interference region, for example, an outer contour formed by the outer end trace of the first brush member and at least a portion of an outer contour formed by the outer end trace of the second brush member interfere with each other, and in some embodiments, when the first rolling brush and the second rolling brush rotate, there is no contact between the first brush member and the second brush member or there is a mutual overlap between the first brush member and the second brush member. Specifically, as shown in fig. 28 and 29, the first long brush member 131 and the second long brush member 231 interfere with each other between the first roll brush 100 and the second roll brush 200, forming an interference region. The air inlet passage between the two rolling brushes is at least partially closed, the opening size of the air inlet passage is reduced, the dust collection pressure is increased, and a better dust collection effect is realized.
The first brush member and the second brush member rotate to the positions close to each other along with the first rolling brush and the second rolling brush, the adjacent points of the first brush member and the second brush member dynamically move along a predetermined direction along with the rotation of the two rolling brushes, and the interference area is configured to dynamically move along the predetermined direction, for example, along the extending direction of the first rolling brush 100 and the second rolling brush 200, so that dust on all positions of the operation surface cleaned by the rolling brushes has a chance to be sequentially sucked into the air duct with a larger suction force and then enter the dust box. The duct inlet 5410 of the duct 5400 is disposed downstream of the predetermined direction to facilitate dust entering the dust box through the duct.
In some embodiments, as shown in fig. 27 to 29, the first roll brush 100 includes a first shaft 110 and a first brush member 130. The first shaft 110 may be a rod-like structure, such as an elongated cylindrical structure. The two ends of the rod-like structure may be detachably mounted to the bottom of the apparatus body of the automatic cleaning apparatus directly or through a connection member. In some embodiments, the first shaft 110 is detachably mounted to the bottom of the device body in an elongated groove structure extending along the transverse axis Y, along with a first brush member 130 disposed on the first shaft 110.
The axis of the first shaft 110 may be regarded as a rotation axis of the first rolling brush 100, and when the first rolling brush 100 is mounted to the apparatus main body of the automatic cleaning apparatus, a driving system located on the apparatus main body can drive the first shaft 110 to rotate, and the rotation direction may be clockwise or counterclockwise. When the first shaft 110 rotates, other components disposed on the first shaft 10, such as the first brush member 130, can be driven to rotate together for cleaning purposes.
The first brush member 130 is detachably mounted on the first shaft 110, facilitating replacement of the first brush member 130 as a consumable. The first brush member 130 includes a first cylindrical member 133 and a first long brush 131.
The first cylindrical member 133 is configured to fit over the first shaft 110 such that the first cylindrical member 130 is coaxial with the first shaft 110. The first cylindrical member 130 may have a long cylindrical structure, and the length of the first cylindrical member 130 is substantially the same as the length of the first shaft 110. The first cylindrical member 130 is tightly sleeved on the first shaft 110, and the inner diameter of the first cylindrical member 130 is substantially equal to or slightly smaller than the diameter of the first shaft 110, so that no relative movement occurs between the first shaft 110 and the first cylindrical member 130 during the rotation process. The first tubular member 130 may be, for example, a flexible member.
The first long brush 131 is a first long blade, and extends from the outer surface of the first tubular member 130 in a direction away from the first tubular member. In some embodiments, the first long brush 131 is integrally formed with the first tubular member 130, e.g., integrally formed of the same material.
The second roll brush 200 includes a second shaft 210 and a second brush member 230. The second shaft 210 may be a rod-like structure, such as an elongated cylindrical structure. The two ends of the rod-like structure may be detachably mounted to the bottom of the apparatus body of the automatic cleaning apparatus directly or through a connection member. In some embodiments, the second shaft 210 is detachably mounted to the bottom of the device body in an elongated groove structure extending in the lateral axis Y direction, along with the second brush member 230 provided on the second shaft 210.
The axis of the second shaft 210 may be regarded as a rotation axis of the second rolling brush 200, and when the second rolling brush 200 is mounted to the apparatus main body of the automatic cleaning apparatus, a driving system disposed on the apparatus main body can drive the second shaft 210 to rotate, and the rotation direction may be clockwise or counterclockwise. When the second shaft 210 rotates, other components disposed on the second shaft 210, such as the second brush member 230, are driven to rotate together, so as to achieve the cleaning purpose.
The second brush member 230 is detachably mounted on the second shaft 210, facilitating replacement of the second brush member 230 as a consumable. The second brush member 230 includes a second cylindrical member 233 and a second long brush 231.
The second tubular member 233 is configured to fit over the second shaft 210 such that the second tubular member 230 is coaxial with the second shaft 210. The second cylindrical member 230 may have an elongated cylindrical structure, and the length of the second cylindrical member 230 is substantially the same as the length of the second shaft 210. The second cylindrical member 230 is tightly sleeved on the second shaft 210, and the inner diameter of the second cylindrical member 230 is substantially equal to or slightly smaller than the diameter of the second shaft 210, so that the second shaft 210 and the second cylindrical member 230 do not move relatively during rotation. The second cylindrical member 230 may be, for example, a flexible member.
The second long brush 231 is a second long blade, and extends from the outer surface of the second tubular member 230 in a direction away from the second tubular member. In some embodiments, the second long brush 231 is integrally formed with the second tubular member 230, e.g., integrally formed of the same material.
In some embodiments, as shown in fig. 27 to 29, the number of the first long brushes 131 and the second long brushes 231 is plural, and the plural first long brushes 131 are in one-to-one correspondence with the plural second long brushes 231, and any one of the plural first long brushes 131 is configured to interfere with the corresponding second long brush 231. Specifically, as shown in fig. 28 and 29, the first roll brush 100 has 5 first long brush members 131, and the second roll brush 200 has 5 second long brush members 231. Each of the first long brush members 131 and the corresponding second long brush member 231 are respectively rotated to a position close to each other with the first and second rolling brushes 100 and 200, for example, between the first and second rolling brushes 100 and 200, and interfere with each other. The first long brush member 131 and its corresponding second long brush member 231 interfere, for example, from one end portion, and as the first and second roller brushes 100 and 200 further rotate, the interference region of the two moves from one end portion to the other end portion. With further rotation of the first and second rolling brushes 100 and 200, the two are separated from interference, and thus, are cyclically reciprocated.
In some embodiments, as shown in fig. 27 to 29, at least one pair of corresponding first long brush 131 and second long brush 231 interfere with each other at any one time when the automatic cleaning apparatus performs a cleaning operation. Specifically, fig. 29 shows a case where two pairs of the first long brush 131 and the second long brush 231 interfere with each other at the same time. D1 shows one pair of the first long brush 131 and the second long brush 231 in an interference state at one end, and D2 shows the other pair of the first long brush 131 and the second long brush 231 in an interference state at the other end. By the arrangement, the area of the interference area can be properly increased, the opening size of the air inlet channel is further reduced, the dust collection pressure is increased, and a better dust collection effect is realized.
In some embodiments, as shown in fig. 27 to 29, the plurality of first long brushes 131 are uniformly distributed in the circumferential direction of the first cylindrical member 133. The plurality of second long brushes 231 are uniformly distributed in the circumferential direction of the second cylindrical member 233. For example, the number of the plurality of first long brushes 131 is 5, and one first long brush 131 is provided every 72 degrees in the circumferential direction of the first cylindrical member 133. For example, the number of the plurality of second long brushes 231 is 5, and one second long brush 131 is provided every 72 degrees in the circumferential direction of the second tubular member 233.
In some embodiments, the first long brush 131 extends from one end to the other end of the first cylindrical member 133, which does not extend along the axis of the first cylindrical member 133, but is meandering, e.g., spiral, on the outer peripheral surface of the first cylindrical member 133. Each of the first long brushes 131 covers a first predetermined angle in the circumferential direction of the first cylindrical member 133, the first and predetermined angles being 360 °/N or more, wherein N is the number of the first long brushes, wherein N is a positive integer and N is not less than 2. The second long brush 231 extends from one end portion to the other end portion of the second tubular member 233, and is not extended along the axis of the second tubular member 233, but is meandering, for example, spirally provided, on the outer peripheral surface of the second tubular member 233. Each of the second long brushes 231 covers a second predetermined angle in the circumferential direction of the second cylindrical member 233, the second predetermined angle being 360 °/N or more, wherein N is the number of the second long brushes, wherein N is a positive integer and N is not less than 2.
Such an arrangement may enable at least two adjacent pairs of the first long brush 131 and the second long brush 231 to be simultaneously in an interference state. The air inlet passage between the two rolling brushes is at least partially closed, the opening size of the air inlet passage is reduced, the dust collection pressure is increased, and a better dust collection effect is realized.
In some embodiments, as shown in fig. 27 to 29, when the automatic cleaning apparatus performs a cleaning job, the first and second rolling brushes 100 and 200 are rotated in opposite directions, the first rolling brush 100 is rotated in a first rotation direction R1, for example, in a counterclockwise direction, and the second rolling brush 200 is rotated in a second rotation direction R2, which is opposite to the first rotation direction, for example, in a clockwise direction. So arranged, the first and second rolling brushes 100 and 200 push the dust and other garbage picked up by the first and second long brush members 131 and 231 between the first and second rolling brushes 100 and 200, so that the dust and other garbage can enter the dust box through the air duct 5400.
In some embodiments, as shown in fig. 27 to 29, the first long brush 131 extends spirally from one end of the first cylindrical member 133 to the other end of the first cylindrical member 133 in the second rotation direction R2 on the outer surface of the first cylindrical member 133. The second rotation direction R2 is, for example, a homeotropic direction. The second long brush 231 extends spirally from one end of the second tubular member 233 to the other end of the second tubular member 233 in a first rotation direction R1, for example, a reverse needle direction, on the outer surface of the second tubular member 233.

As the first and second roll brushes 100 and 200 further rotate, the interference region of the two gradually moves along the transverse axis Y in fig. 30 to the middle of the combined body of the first and second roll brushes 100 and 200, as shown at D5 in fig. 29. With further rotation of the first and second rolling brushes 100 and 200, the two are separated from interference, and thus, are cyclically reciprocated.

The following description is made with reference to fig. 27 to 31, and the same structure is as described in the previous embodiment, which is not repeated herein, and the cleaning module 5000 includes a first rolling brush 100, a second rolling brush 200 and an air duct 5400. The first and second roller brushes 100 and 200 constitute the aforementioned roller brush 5300. The first roll brush 100 includes a first brush member including a first long brush member 131 and a first short brush member 132, and the second roll brush 200 includes a second brush member including a second long brush member 231 and a second short brush member 232.
The first roll brush 100, for example a front brush, is arranged in a first direction perpendicular to the axis of the moving platform, for example the front-rear axis X, and the first direction, for example the direction in which the transverse axis Y extends. The first rolling brush 100 includes a first long brush member 131, i.e., a first long blade, which is relatively long and thin, and can contact with the ground to flap up dust, hair, etc. to be cleaned and then be sucked into a dust box when treating a flat and hard cleaning surface of a tile, a wooden floor, etc. The contact force between the long blade and the ground is small, cleaning is daily with low noise.
The second rolling brush 200, for example, a rear brush, is disposed along a first direction perpendicular to the axis of the moving platform, and the second rolling brush 200 includes a second long brush member 231, i.e., a second long blade.
The air duct 5400 is disposed at a side of the first and second roller brushes 100 and 200 away from the operation surface, and configured to guide dust to be accommodated, for example, to a dust box.
The rolling brush chamber 5210 is a cavity with an opening at the bottom and facing the ground, the rolling brush chamber 5210 sucks in the chips and dust on the ground through the opening, thereby cleaning the ground, and the top of the rolling brush chamber 5210 is communicated with the air duct 5400 through the air duct opening.
Wherein the first long brush 131 and the second long brush 231 interfere with each other and the first long brush 131 and the second long brush 231 do not interfere with the inner wall of the rolling brush chamber 5210 when the automatic cleaning apparatus performs a cleaning operation, and the interference amount of the first long brush 131 and the second long brush 231 increases and the first long brush 131 and the second long brush 231 interfere with the inner wall of the rolling brush chamber 5210 when the automatic cleaning apparatus performs a dust collecting operation.
In the actual use, through two different pivoted round brushes, inhale the dust in to round brush chamber 5210, and contact through long blade between two round brushes to make the long blade that two round brushes contacted each other in the use form individual volume in order to absorb the dust, such design is less not only the noise, has also avoided dust and piece to be thrown away, and other debris and rubbish also can be inhaled the space in two round brushes, have improved dust collection efficiency by a wide margin.
As shown in fig. 28, the top of the rolling brush chamber 5210 forms two arc chamber cambered surfaces respectively, each chamber cambered surface is close to one rolling brush and is not contacted with the rolling brush, when the automatic cleaning device executes cleaning operation, each rolling brush reversely rotates along the inclined direction of the long blade, the first long brush member 131 and the second long brush member 231 mutually interfere with each other, but the interference quantity is relatively small, so that the rotation is smooth and unimpeded, and garbage is conveniently and smoothly involved. When the automatic cleaning device performs dust collection operation, each rolling brush rotates along the inclined direction of the long blade, the inclined angle of the long blade is reduced due to the flexibility and centrifugal force of the long blade, for example, the long blade is in a state approximately perpendicular to the cylindrical component, at the moment, the long blade can scrape or flap with the cavity cambered surface of the rolling brush cavity 5210, so that dust on the blade and the cavity cambered surface can fall off, and self-cleaning of the rolling brush cavity 5210 and the long blade is realized.
As shown in fig. 28, during normal cleaning, the front and rear brushes are rolled up inwardly toward the middle, the corresponding front brush rotates counterclockwise, and the rear brush rotates clockwise. The front brush is inclined clockwise, the rear brush is inclined anticlockwise, the direction of the contact force applied to the rolling brush during cleaning is just the direction of deformation of the blades, and the sound of beating the ground contact is the softest, so that noise is reduced. When the main brush rotates reversely, the blades deform in the direction of increasing the diameter (the blades deform clockwise) after receiving the contact force, and the blades can scrape the inner wall for self cleaning (the blades rotate at a high speed and the diameter is increased by centrifugal force).
In some embodiments, the first elongate brush member 131 has a root portion proximal to the first tubular member 133 and a tip portion distal to the first tubular member 133, the first elongate brush member root portion having a thickness less than a thickness of the first elongate brush member tip portion, and/or the second elongate brush member 231 has a root portion proximal to the second tubular member 233 and a tip portion distal to the second tubular member, the second elongate brush member root portion having a thickness less than a thickness of the second elongate brush member tip portion. This ensures that the first long brush member 131 and/or the second long brush member 231 is inclined to one side in the normal rotation state and is swung to the other side in the reverse rotation state to increase the flapping effect thereof with the inner wall of the roll brush chamber 5210.
In some embodiments, the first long brush 131 has a first width along the first long brush root to the first long brush top that is greater than the spacing of the first roller brush 100 from the inner wall of the roller brush chamber 5210, and/or the second long brush 231 has a second width along the second long brush root to the second long brush top that is greater than the spacing of the second roller brush 200 from the inner wall of the roller brush chamber 5210. So that the first long brush member 131 and the second long brush member 231 have a sufficient length to be able to make contact with the inner wall of the roller brush chamber 5210 to perform flapping in the reverse dust collecting state of the roller brush.
When the automatic cleaning apparatus performs a cleaning operation, the first and second rolling brushes 100 and 200 roll in opposite directions to perform a cleaning operation.

The air inlet passage between the two rolling brushes is at least partially closed, the opening size of the air inlet passage is reduced, the dust collection pressure is increased, and a better dust collection effect is realized.
The interference area is configured to move dynamically in a predetermined direction, for example, in a direction in which the first and second roller brushes 100 and 200 extend, so that dust at all positions of the operation surface cleaned by the roller brushes has a chance to be sucked into the air duct in sequence with a greater suction force and then into the dust box. The duct inlet 5410 of the duct 5400 is disposed downstream of the predetermined direction to facilitate dust entering the dust box through the duct.
