本申请涉及清洁技术领域，特别是涉及一种表面清洁装置。The present application relates to the field of cleaning technology, in particular to a surface cleaning device.
背景技术Background technique
表面清洁装置是一种可以提供清洁功能的家用电器，例如擦窗机器人、扫地机器人等自移动表面清洁装置；或者，需要用户拖动或手持的非自移动表面清洁装置。以擦窗机器人为例，擦窗机器人的底部通常设有抹布支架，抹布支架的底部设有凹腔，该凹腔用于与待清洁表面界定出密封空间，当该密封空间内产生负压时，可以使擦窗机器人吸附在待清洁表面。A surface cleaning device is a household appliance that can provide cleaning functions, such as self-moving surface cleaning devices such as window cleaning robots and sweeping robots; or non-self-moving surface cleaning devices that need to be dragged or held by the user. Take the window-cleaning robot as an example. The bottom of the window-cleaning robot is usually equipped with a rag holder, and the bottom of the rag holder is provided with a cavity. The cavity is used to define a sealed space with the surface to be cleaned. When negative pressure is generated in the sealed space , the window cleaning robot can be attached to the surface to be cleaned.
为了提高擦窗机器人的清洁效果以及越障能力，抹布支架通常与擦窗机器人朝向待清洁表面的一侧浮动连接，即抹布支架可以相对擦窗机器人朝向待清洁表面的一侧上下浮动。但是，抹布支架的浮动设置将会影响抹布支架与擦窗机器人底部的密封效果，存在密封空间漏气失压，造成擦窗机器人从待清洁表面掉落的风险。针对该问题，现有技术中的一种解决方案为，在擦窗机器人底部与抹布支架之间设置海绵条，通过海绵条对抹布支架与擦窗机器人底部之间的空间进行密封，且海绵条的弹性可以适应擦窗机器人底部与抹布支架之间的位置变化。In order to improve the cleaning effect and obstacle-surmounting ability of the window-cleaning robot, the rag support is usually floatingly connected to the side of the window-cleaning robot facing the surface to be cleaned, that is, the rag support can float up and down relative to the side of the window-cleaning robot facing the surface to be cleaned. However, the floating setting of the mop support will affect the sealing effect between the mop support and the bottom of the window cleaning robot, and there is a risk of air leakage and pressure loss in the sealed space, causing the window cleaning robot to fall from the surface to be cleaned. Aiming at this problem, a solution in the prior art is to arrange a sponge strip between the bottom of the window cleaning robot and the rag support, and seal the space between the rag support and the bottom of the window cleaning robot through the sponge strip, and the sponge strip The elasticity of the window cleaning robot can adapt to the position change between the bottom of the window cleaning robot and the mop support.
但是，海绵条中存在孔隙，尤其是当擦窗机器人底部与抹布支架之间的距离较大时，海绵条中的孔隙较大，导致擦窗机器人底部与抹布支架之间的密封效果较差，失压漏气的问题。However, there are pores in the sponge strip, especially when the distance between the bottom of the window cleaning robot and the rag support is large, the pores in the sponge strip are relatively large, resulting in poor sealing effect between the bottom of the window cleaning robot and the rag support, The problem of pressure loss and air leakage.

具体实施方式Detailed ways
为了使本技术领域的人员更好地理解本申请中的技术方案，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本申请保护的范围。In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described The embodiments are only some of the embodiments of the present application, but not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.
表面清洁装置是一种可以提供清洁功能的家用电器，例如擦窗机器人、扫地机器人等自移动表面清洁装置；或者，需要用户拖动或手持的非自移动表面清洁装置。以擦窗机器人为例，擦窗机器人的底部通常设有抹布支架，抹布支架的底部设有凹腔，该凹腔用于与待清洁表面界定出密封空间，当该密封空间内产生负压时，可以使擦窗机器人吸附在待清洁表面。A surface cleaning device is a household appliance that can provide cleaning functions, such as self-moving surface cleaning devices such as window cleaning robots and sweeping robots; or non-self-moving surface cleaning devices that need to be dragged or held by the user. Take the window-cleaning robot as an example. The bottom of the window-cleaning robot is usually equipped with a rag holder, and the bottom of the rag holder is provided with a cavity. The cavity is used to define a sealed space with the surface to be cleaned. When negative pressure is generated in the sealed space , the window cleaning robot can be attached to the surface to be cleaned.
为了提高擦窗机器人的清洁效果以及越障能力，抹布支架通常与擦窗机器人朝向待清洁表面的一侧浮动连接，即抹布支架可以相对擦窗机器人朝向待清洁表面的一侧上下浮动。但是，抹布支架的浮动设置将会影响抹布支架与擦窗机器人底部的密封效果，存在密封空间漏气失压，造成擦窗机器人从待清洁表面掉落的风险。针对该问题，现有技术中的一种解决方案为，在擦窗机器人底部与抹布支架之间设置海绵条，通过海绵条对抹布支架与擦窗机器人底部之间的空间进行密封，且海绵条的弹性可以适应擦窗机器人底部与抹布支架之间的位置变化。In order to improve the cleaning effect and obstacle-surmounting ability of the window-cleaning robot, the rag support is usually floatingly connected to the side of the window-cleaning robot facing the surface to be cleaned, that is, the rag support can float up and down relative to the side of the window-cleaning robot facing the surface to be cleaned. However, the floating setting of the mop support will affect the sealing effect between the mop support and the bottom of the window cleaning robot, and there is a risk of air leakage and pressure loss in the sealed space, causing the window cleaning robot to fall from the surface to be cleaned. Aiming at this problem, a solution in the prior art is to arrange a sponge strip between the bottom of the window cleaning robot and the rag support, and seal the space between the rag support and the bottom of the window cleaning robot through the sponge strip, and the sponge strip The elasticity of the window cleaning robot can adapt to the position change between the bottom of the window cleaning robot and the mop support.
但是，海绵条中存在孔隙，尤其是当擦窗机器人底部与抹布支架之间的距离较大时，海绵条中的孔隙较大，导致擦窗机器人底部与抹布支架之间的密封效果较差，失压漏气的问题。However, there are pores in the sponge strip, especially when the distance between the bottom of the window cleaning robot and the rag support is large, the pores in the sponge strip are relatively large, resulting in poor sealing effect between the bottom of the window cleaning robot and the rag support, The problem of pressure loss and air leakage.
针对上述问题，本申请实施例提供了一种浮动密封方案，可以在抹布支架与擦窗机器人底部浮动连接的同时，具有较好的密封效果，下面结合附图进行说明。In view of the above problems, the embodiment of the present application provides a floating sealing solution, which can have a better sealing effect while the mop support is floatingly connected to the bottom of the window cleaning robot. The following will be described with reference to the accompanying drawings.
图1为本申请实施例提供的一种表面清洁装置的局部结构示意图，图2为沿图1中A-A方向的一种截面示意图。如图1并结合图2所述，在局部结构中示出了第一支架110、第二支架120以及设置在第一支架110和第二支架120之间的密封条130。FIG. 1 is a schematic partial structure diagram of a surface cleaning device provided by an embodiment of the present application, and FIG. 2 is a schematic cross-sectional view along the direction A-A in FIG. 1 . As described in FIG. 1 and in conjunction with FIG. 2 , the first bracket 110 , the second bracket 120 and the sealing strip 130 disposed between the first bracket 110 and the second bracket 120 are shown in the partial structure.
为了便于说明，在上述局部结构中定义上下方向。其中，该上下方向垂直于第一支架110和/或第二支架120所在的平面，“上方”为表面清洁装置(或者，上述局部结构)远离待清洁表面的一侧，“下方”为表面清洁装置(或者，上述局部结构)远离待清洁表面的一侧。在一些可能的实现方式中，“上方”也可能被称为“顶部”；“下方”也可能被称为“底部”。For convenience of explanation, the up-down direction is defined in the above partial structure. Wherein, the up-down direction is perpendicular to the plane where the first support 110 and/or the second support 120 are located, "above" is the side away from the surface cleaning device (or, the local structure) to be cleaned, and "below" is the surface cleaning surface. The side of the device (or, the aforementioned local structure) facing away from the surface to be cleaned. In some possible implementations, "above" may also be referred to as "top"; "below" may also be referred to as "bottom".
在一种可能的实现方式中，该第一支架110可以为表面清洁装置的底壳或者表面清洁装置的壳体的底部；该第二支架120可以为清洁单元支架，该清洁单元支架上用于设置清洁单元(例如，抹布、海绵等)。当然，该第二支架120还可以为具有其它功能的支架，例如，第二支架120为连接在第一支架110与清洁单元支架之间的连接件，本申请实施例对此不作具体限制。In a possible implementation, the first bracket 110 may be the bottom case of the surface cleaning device or the bottom of the housing of the surface cleaning device; the second bracket 120 may be a cleaning unit bracket, on which the cleaning unit bracket is used A cleaning unit (eg, rag, sponge, etc.) is provided. Of course, the second bracket 120 can also be a bracket with other functions, for example, the second bracket 120 is a connecting piece connected between the first bracket 110 and the cleaning unit bracket, which is not specifically limited in this embodiment of the present application.
下面结合图3-图5，对上述局部结构进行详细说明。The above partial structure will be described in detail below with reference to FIGS. 3-5 .
如图3-图5所示，第二支架120设置在第一支架110的底部，即第二支架120设置在第一支架110靠近第二支架120的一侧，第二支架120可相对第一支架110移动，使得第一支架110和第二支架120之间的位置发生变化。具体地，“第一支架110和第二支架120之间的位置发生变化”可以包括第一支架110和第二支架120之间的距离发生变化，和/或第一支架110和第二支架120之间的相对角度发生变化。例如，当第二支架120相对第一支架110沿上下方向移动时，第一支架110和第二支架120之间的距离发生变化。当第二支架120的第一侧相对第一支架110保持不动，第二支架120的第二侧(与第一侧相对的一侧)相对第一支架110向上移动时，第一支架110和第二支架120之间的相对角度发生变化。也就是说，第二支架120的第二侧向上翘起，使得第一支架110和第二支架120之间处于非平行状态。As shown in Figures 3-5, the second bracket 120 is arranged at the bottom of the first bracket 110, that is, the second bracket 120 is arranged on the side of the first bracket 110 close to the second bracket 120, and the second bracket 120 can be opposite to the first bracket 120. The bracket 110 moves so that the position between the first bracket 110 and the second bracket 120 changes. Specifically, "the position between the first bracket 110 and the second bracket 120 changes" may include that the distance between the first bracket 110 and the second bracket 120 changes, and/or the distance between the first bracket 110 and the second bracket 120 changes. The relative angle between them changes. For example, when the second bracket 120 moves up and down relative to the first bracket 110 , the distance between the first bracket 110 and the second bracket 120 changes. When the first side of the second support 120 remains stationary relative to the first support 110, and the second side of the second support 120 (the side opposite to the first side) moves upward relative to the first support 110, the first support 110 and The relative angle between the second brackets 120 changes. That is to say, the second side of the second bracket 120 is upturned, so that the first bracket 110 and the second bracket 120 are in a non-parallel state.
具体实现中，第二支架120可以通过限位卡槽固定在第一支架110的底部，该限位卡槽在上下方向上保留一定的活动空间，使得第二支架120可以相对第一支架110沿上下方向浮动。当然，本领域技术人员还可以采用其它结构实现第二支架120和第一支架110的浮动连接，本申请实施例对此不作具体限制。In a specific implementation, the second bracket 120 can be fixed on the bottom of the first bracket 110 through a limit card slot, and the limit card slot reserves a certain movable space in the up and down direction, so that the second bracket 120 can be moved along with the first bracket 110. Float up and down. Of course, those skilled in the art may also use other structures to realize the floating connection between the second bracket 120 and the first bracket 110 , which is not specifically limited in this embodiment of the present application.
为了将表面清洁装置吸附在待清洁表面，第二支架120的底部设有凹腔121，该凹腔121用于与待清洁表面界定出密封空间。另外，第一支架110上设有通风孔111，表面清洁装置上的真空模组(例如，泵模组或风机模组)通过通风孔111与第二支架120底部的凹腔121相连通，以在凹腔121与待清洁表面之间界定出的密封空间内产生负压。也就是说，上述凹腔121、通风孔111均处于负压空间内。In order to adsorb the surface cleaning device on the surface to be cleaned, a concave cavity 121 is provided at the bottom of the second bracket 120, and the concave cavity 121 is used to define a sealed space with the surface to be cleaned. In addition, the first bracket 110 is provided with a ventilation hole 111, and the vacuum module (for example, a pump module or a fan module) on the surface cleaning device communicates with the concave cavity 121 at the bottom of the second bracket 120 through the ventilation hole 111, so as to Negative pressure is generated in the sealed space defined between the cavity 121 and the surface to be cleaned. That is to say, the above-mentioned concave cavity 121 and the vent hole 111 are all in the negative pressure space.
可理解，若第一支架110和第二支架120之间存在缝隙，会造成负压空间漏气，即造成负压空间失压。基于此，本申请实施例在第一支架110和第二支架120之间还设有密封条130，该密封条130环绕密封第一支架110和第二支架120之间的空间。需要指出的是，该“环绕密封第一支架110和所述第二支架120之间的空间”并非在第一支架110和第二支架120之间形成一个绝对的密封空间(第一支架110上还可能存在通风孔111，第二支架120上还可能存在与通风孔111相连通的凹腔121)，而是在第一支架110和第二支架120之间形成一密封环，避免第一支架110和第二支架120之间的缝隙漏气。可理解，通风孔111和凹腔121应当位于密封条130所环绕的密封区域内。It can be understood that if there is a gap between the first support 110 and the second support 120 , it will cause air leakage in the negative pressure space, that is, cause the negative pressure space to lose pressure. Based on this, in the embodiment of the present application, a sealing strip 130 is further provided between the first bracket 110 and the second bracket 120 , and the sealing strip 130 surrounds and seals the space between the first bracket 110 and the second bracket 120 . It should be pointed out that the "surround seal the space between the first bracket 110 and the second bracket 120" does not form an absolute sealed space between the first bracket 110 and the second bracket 120 (on the first bracket 110 There may also be a ventilation hole 111, and there may also be a concave cavity 121 communicating with the ventilation hole 111 on the second bracket 120), but a sealing ring is formed between the first bracket 110 and the second bracket 120 to avoid the first bracket 110 and the gap between the second bracket 120 leaks air. It can be understood that the ventilation hole 111 and the concave cavity 121 should be located in the sealing area surrounded by the sealing strip 130 .
为了适应第一支架110和第二支架120之间的位置变化，本申请实施例提供的密封条130上还设有形变部，该形变部的形变用于适应第一支架110和第二支架120之间的位置变化。In order to adapt to the position change between the first bracket 110 and the second bracket 120, the sealing strip 130 provided in the embodiment of the present application is also provided with a deformation part, and the deformation of the deformation part is used to adapt to the first bracket 110 and the second bracket 120 position changes between.
在一种可能的实现方式中，该形变部为设置在密封条130上的褶皱134(如图3-图5所示)。可理解，当第一支架110和第二支架120之间的距离变大时，密封条130上的褶皱134会被拉伸；当第一支架110和第二支架120之间的距离变小时，密封条130上的褶皱134会被压缩。也就是说，密封条130上的褶皱134可以适应第一支架110和第二支架120之间的位置变化，在第二支架120相对第一支架110浮动的过程中，密封条130始终可以保持较好的密封效果。In a possible implementation manner, the deformation portion is a fold 134 provided on the sealing strip 130 (as shown in FIGS. 3-5 ). It can be understood that when the distance between the first bracket 110 and the second bracket 120 becomes larger, the folds 134 on the sealing strip 130 will be stretched; when the distance between the first bracket 110 and the second bracket 120 becomes smaller, The folds 134 on the sealing strip 130 are compressed. That is to say, the folds 134 on the sealing strip 130 can adapt to the position change between the first bracket 110 and the second bracket 120, and the sealing strip 130 can always keep relatively tight during the floating process of the second bracket 120 relative to the first bracket 110. Good sealing effect.
在另一种可能的实现方式中，该形变部为设置在密封条130上的弹性形变区域，该弹性形变区域可以在外力的作用下产生弹性形变，并且在外力消失后，恢复至原始状态。可理解，当第一支架110和第二支架120之间的距离变大时，会在密封条130上的弹性形变区域产生拉力，进而使得该弹性形变区域产生弹性形变(被拉伸)；当第一支架110和第二支架120之间的距离变小时，施加在弹性形变区域的拉力变小或消失，使得弹性形变区域产生的弹性形变变小或消失(恢复至原始状态)。也就是说，密封条130上的弹性形变区域可以适应第一支架110和第二支架120之间的位置变化，在第二支架120相对第一支架110浮动的过程中，密封条130始终可以保持较好的密封效果。In another possible implementation manner, the deformation portion is an elastic deformation region provided on the sealing strip 130 , the elastic deformation region can be elastically deformed under the action of an external force, and return to its original state after the external force disappears. It can be understood that when the distance between the first bracket 110 and the second bracket 120 becomes larger, tension will be generated in the elastic deformation region on the sealing strip 130, and then the elastic deformation region will be elastically deformed (stretched); When the distance between the first bracket 110 and the second bracket 120 becomes smaller, the tension applied to the elastic deformation area becomes smaller or disappears, so that the elastic deformation generated by the elastic deformation area becomes smaller or disappears (returns to the original state). That is to say, the elastic deformation area on the sealing strip 130 can adapt to the position change between the first bracket 110 and the second bracket 120, and the sealing strip 130 can always maintain the position when the second bracket 120 floats relative to the first bracket 110. Better sealing effect.

Slot 112 is separated. Specifically, the first fixing member 141 and the first bracket 110 may be fixedly connected by connecting members (for example, screws or adhesives, etc.), or the first fixing member 141 may be fixed on the first bracket 110 by a limiting member ( For example, in FIG. 5 , the first fixing member 141 is fixed on the first bracket 110 through the limiting member on the second bracket 120 ), which is not specifically limited in this embodiment of the present application. The second fixing part 142 is fixedly connected with the second bracket 120, and the second fixing part 142 is used for abutting the second protruding ring 133 in the second groove 122, so as to prevent the second protruding ring 133 from loosening or colliding with the second groove 122. separate.

在一些可能的实现方式中，第一固定件141和第二固定件142为板状结构，当然，本领域技术人员还可以将第一固定件141和第二固定件142设置为其它形状，本申请实施例对此不作具体限制。In some possible implementations, the first fixing member 141 and the second fixing member 142 are plate-shaped structures. Of course, those skilled in the art can also set the first fixing member 141 and the second fixing member 142 into other shapes. The embodiment of the application does not specifically limit this.
在实际应用中，由于第一支架110和第二支架120的结构限制，可能不便于通过固定件直接将凸环抵顶在凹槽内，或者固定件仅能抵压住部分凸环。例如，图3-图5所示的第一凸环131。在该应用场景中，还可以在第一凸环131上设置第一裙边132，通过第一固定件141还将第一裙边132抵顶在第一支架110的底部，避免第一凸环131松动或与第一凹槽112分离。当然，本领域技术人员还可以根据实际需要在第二凸环133上还设置第二裙边，通过第二固定件142将第二裙边抵顶在第二支架120的顶部，避免第二凸环133松动或与第二凹槽122分离，本申请实施例对此不作具体限制。In practical applications, due to structural limitations of the first bracket 110 and the second bracket 120 , it may not be convenient to directly press the protruding ring against the groove through the fixing member, or the fixing member can only press part of the protruding ring. For example, the first protruding ring 131 shown in FIGS. 3-5 . In this application scenario, the first skirt 132 can also be provided on the first convex ring 131, and the first skirt 132 can also be pressed against the bottom of the first bracket 110 through the first fixing member 141, so as to avoid the first convex ring 131 is loose or separated from the first groove 112 . Of course, those skilled in the art can also set a second skirt on the second protruding ring 133 according to actual needs, and push the second skirt against the top of the second bracket 120 through the second fixing member 142 to avoid the second protruding ring 133. The ring 133 is loose or separated from the second groove 122 , which is not specifically limited in this embodiment of the present application.
可理解，为了保证凸环和凹槽连接位置的密封效果，凸环和凹槽应当具有较高的加工精度，以实现凸环和凹槽的紧密贴合。相反，若凸环和凹槽贴合的不紧密，则会导致凸环和凹槽的连接位置漏气。It can be understood that, in order to ensure the sealing effect of the connection position between the convex ring and the groove, the convex ring and the groove should have relatively high machining accuracy, so as to realize the tight fit between the convex ring and the groove. On the contrary, if the protruding ring and the groove are not closely fitted, it will cause air leakage at the connecting position of the protruding ring and the groove.
在一种可能的实现方式中，第一凸环131上还设有沿第一凸环131延伸的第一凸环凹槽1311，该第一凸环凹槽1311可以增加第一凸环131在第一凸环凹槽1311附近区域的形变量。即使第一凸环131和第一凹槽112的加工精度较低，在第一凸环131的形变作用下，仍然使得第一凸环131和第一凹槽112具有较好的贴合效果，进而可以保证第一凸环131和第一凹槽112连接位置的密封效果。同理，在第二凸环133上还设有沿第二凸环133延伸的第二凸环凹槽1331，进而可以保证第二凸环133和第二凹槽122连接位置的密封效果。In a possible implementation manner, the first convex ring 131 is further provided with a first convex ring groove 1311 extending along the first convex ring 131 , and the first convex ring groove 1311 can increase the The amount of deformation in the vicinity of the groove 1311 of the first convex ring. Even if the processing accuracy of the first protruding ring 131 and the first groove 112 is low, under the deformation of the first protruding ring 131, the first protruding ring 131 and the first groove 112 still have a good bonding effect, Furthermore, the sealing effect of the connection position between the first protruding ring 131 and the first groove 112 can be ensured. Similarly, the second protrusion ring 133 is further provided with a second protrusion ring groove 1331 extending along the second protrusion ring 133 , thereby ensuring the sealing effect of the connection position between the second protrusion ring 133 and the second groove 122 .
当然，为了保证密封效果，还可以将第一支架110、第二支架120和密封条130采用一体成型的方式设计，本申请实施例对此不作具体限制。Certainly, in order to ensure the sealing effect, the first support 110 , the second support 120 and the sealing strip 130 may also be designed in an integrated manner, which is not specifically limited in this embodiment of the present application.
