Detailed Description
The preferred embodiments of the present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1, an electronic cigarette 10 includes a power supply 200 and an electronic atomizer 100, where the power supply 200 and the electronic atomizer 100 are designed by using a plug bush. After the power supply 200 and the electronic atomizer 100 are assembled in a matched manner, the overall appearance structure of the electronic cigarette 10 is formed. The power supply 200 provides the electronic atomizer 100 with an operating voltage, and evaporates the tobacco tar or atomized liquid in the electronic atomizer 100 to emit atomized vapor for the user to suck.
In the embodiment of the present invention, the electronic cigarette 10 has a strip flat structure, the electronic atomizer 100 is a disposable electronic atomizer, and after the tobacco tar or atomized liquid in the electronic atomizer 100 is used up, a part of the components reserved in the electronic atomizer 100 are recycled again to discard the rest components. Thus, the use cost can be greatly reduced, and the environmental pollution can be reduced.
Of course, in other embodiments, the electronic atomizer 100 may be discarded as a whole after the tobacco tar or atomized liquid in the electronic atomizer 100 is exhausted.
As shown in fig. 2a, 2b, and 3 to 8, the electronic atomizer 100 provided by the invention comprises an oil storage cavity 160 and an atomization seat 120, wherein the oil storage cavity 160 is provided with the oil storage cavity 162 and an atomization cavity 1650, the atomization cavity 1650 is arranged on the outer surface of the oil storage cavity 160, and an oil guide hole 1651 is arranged between the oil storage cavity 162 and the atomization cavity 1650; an oil guiding medium 12 and a heating device 150 are detachably arranged in the atomizing cavity 1650; the atomization seat 120 is in fit and clamping connection with the oil storage cavity 160, and the atomization cavity 1650 is contained in the atomization seat 120, and the atomization cavity 1650 and the atomization seat 120 form an air flow through; ambient air enters the atomizing chamber 1650 through the inlet apertures 1210. Preferably, the nozzle base 110 is inserted on the atomizing base 120; the oil storage cavity 160, the atomizing base 120 and the nozzle base 110 form an overall shape of the electronic atomizer 100, and an air flow through is formed among the atomizing cavity 1650, the atomizing base 120 and the nozzle base 110.
Specifically, the oil storage cavity 160 of the electronic atomizer 100 is fixedly connected with the atomization seat 120 by adopting a detachable clamping structure, so that the electronic atomizer is convenient to detach; and the periphery of the back side plate 1611 of the oil storage cavity 160 is provided with a sealing groove 166, and sealing silica gel 101 is arranged in the sealing groove 166 in an adaptation mode and is used for sealing the contact surface of the oil storage cavity 160 and the atomizing seat 120 after the oil storage cavity is clamped.
The oil storage cavity 160 is arranged in a strip shape along the longitudinal Y direction, and comprises a cavity shell 161, wherein the cavity shell 161 is provided with the oil storage cavity 161, and the upper opening end 1621 of the oil storage cavity 160 is opened. An atomizer chamber 1650 is provided on the surface of the back side plate 1611 of the reservoir 160, i.e., the side plate facing the atomizer base 120. The atomization cavity 1650 may be formed by concave surface of a back side plate 1611 of the oil storage cavity 160, or may be formed by arranging an outwardly convex surrounding plate 165 on the surface of the back side plate 1611 of the oil storage cavity 160, and surrounding the surrounding plate 165 to form an inner hollow atomization cavity 1850; accordingly, the coaming plate 165 forms the atomizing chamber wall. Because the back side of the oil storage chamber 160 is concaved inward to form the atomization chamber 1650, the space of the oil storage chamber 162 is inevitably occupied, so that the space of the oil storage chamber 162 is reduced, and the loading amount of the tobacco tar or the atomized liquid is correspondingly reduced, which results in reduction of the pumping frequency of the electronic atomizer 100 by a user. Therefore, in this embodiment, the outer protruding surrounding plate 165 is used to form the atomizing chamber 1650, and the surrounding plate 165 has four pieces, and forms an atomizing chamber 1650 with a rectangular cross section after surrounding. In other embodiments, the surrounding plate 165 may be a surrounding plate, forming an atomization cavity with a circular cross-section; or two surrounding plates to form an atomization cavity 1650 with an elliptical hole-shaped cross section.
In this embodiment, in order to ensure smooth oil guiding, two oil guiding holes 1651 are provided between the atomizing chamber 1650 and the oil storage chamber 162, and the two oil guiding holes 165 are disposed in an up-down positional relationship in the atomizing chamber 1650 along the longitudinal Y direction. Meanwhile, notches (163, 1631) are respectively formed in the two surrounding plates 165 arranged along the longitudinal Y direction; wherein an aperture between the recess 163 at the upper end of the atomizing chamber 1650 and the air flow guide block 130 forms a part of the atomizing passage 1301, and atomizing steam formed in the atomizing chamber 1650 is introduced into the atomizing passage 1301 through the recess 163; the recess 1631 at the lower end of the atomizing chamber 1650 is in communication with the air inlet 1210 to direct ambient air into the atomizing chamber 1650.
An oil medium 102 and a heat generating device 150 are installed in the atomizing chamber 1650. The external configuration of the oil medium 102 and the heat generating device 150 is adapted to the atomizing chamber 1650, and the oil medium 102 and the heat generating device 150 are detachably mounted in the atomizing chamber 1650, that is, the oil medium 102 and the heat generating device 150 can be detached from the atomizing chamber 1650 by a user according to the need. Thus, when the smoke or aerosol is exhausted from the oil storage chamber, the user can remove the oil guide medium 102 and the heat generating device 150, and reinstall the smoke or aerosol in the aerosol chamber 1650 of another smoke-filled oil storage chamber 160, and discard the old oil storage chamber 160. The repeated use of the oil guide medium 102 and the heating device 150 can greatly reduce the use cost and reduce the environmental pollution. When the oil guide medium 102 is installed, the oil guide hole 1651 is closely contacted with the oil guide medium 102, and the heating device 150 is closely contacted with the oil guide medium 102; in this way, the tobacco tar or atomized liquid in the reservoir 162 is guided to the oil guiding medium 102 through the oil guiding hole 1653, and is saturated. In use, the heating device 150 heats under the operating voltage provided by the power supply 200, evaporates the tobacco tar or atomized liquid in the oil guiding medium 102, and emits atomized steam, also called "smog", which enters the atomizing channel 1301 through the atomizing chamber 1650 and the notch 163 on the enclosing plate 165.
The oil guiding medium 102 is one of glass fiber, asbestos, non-woven fabric, cotton, porous ceramic and porous diatomite. In this example, a square block made of glass fiber which is resistant to high temperature, has high oil absorption and is low in cost is preferable.
Preferably, as shown in fig. 9a and 9b, the heating device 150 includes a heating wire 152 and a heating wire holder 151; the heating wire 152 is formed by bending in a roundabout way along a plane shape and has a square plane structure; the heating wire 152 is fixedly installed at one surface of the heating wire holder 151. The heating wire bracket 151 is made of ceramic material, the surface structure is square, the middle part forms a hollow cavity 1510, and the heating wire 152 is integrally manufactured by sintering and then is arranged on one surface of the heating wire bracket 151 and suspended in the hollow cavity 1510. On two opposite side edges of one side of the heating wire bracket 151 facing away from the heating wire 152, column blocks 1511 having the same height are provided in the same direction, respectively, and the gap between the two column blocks 1511 forms a channel 1512, and the channel 1512 and the two notches (163, 1631) on the surrounding plate 165 form part of the atomizing channel 1301. Preferably, a plurality of through holes 1513 are formed in the heating wire bracket 151, and the plane where the heating wire 152 is located is perpendicular to the plane, so that the heating wire bracket 151 is hollow. After heating the tobacco tar or atomized liquid on the oil guiding medium 102 by the heating device 150, atomized steam enters the atomization channel 1301 along the channel 1512 through the hollow cavity 1510 and the through hole 1513 on the heating wire bracket 151.
Further, as shown in fig. 3,4, 10a and 10b, a heating device bracket 140 is further disposed in the atomizing chamber 1650, the heating device 150 is disposed on the heating device bracket 140, and the oil guiding medium 102, the heating device 150 and the heating device bracket 140 are sequentially disposed away from the oil storage chamber from inside to outside to form a stacked arrangement.
Specifically, the heat generating device support 140 is a frame structure, and is made of plastic or silica gel, a hollow slot 141 is provided in the middle, and the size and shape of the hollow slot 141 are consistent with those of the heat generating device 150, so as to fit the heat generating device 150. Air guide grooves 142 are formed in two opposite sides of the hollow groove 141 in the longitudinal Y direction. The oil guiding medium 102, the heating device 150 and the heating device bracket 140 are sequentially far from the oil storage cavity 160 from inside to outside along the horizontal X direction to form a relatively stacked arrangement. When in use, the heating device 150 atomizes the atomized steam generated by the atomized liquid on the oil guiding medium 102 and enters the atomization channel 1301 through the central control slot 141 and the air guiding slot 142.
As shown in fig. 3,4, 7, 8 and 14, the atomizing base 120 is a semi-open structure having an inner cavity 1211. After the oil storage cavity 160 is engaged with the atomization seat 120, the surrounding plate 1650 on the oil storage cavity 160 and the atomization cavity 165 formed by the surrounding plate are received in the inner cavity 1211 of the atomization seat 120. The bottom surface of the inner cavity 1211 is provided with a lower groove 123, the lower groove 123 is provided with two extending grooves (1233,1234) along the longitudinal direction Y, the cross section of the lower groove 123 formed along the longitudinal direction Y is in a ten-shaped structure and is used for accommodating the air flow guide block 130 in an adapting mode, and the appearance structure and the size of the lower bottom surface of the air flow guide block 130 are consistent with the space structure and the size of the lower groove 123 and the space structure and the size of the space formed by the two extending grooves (1233,1234) so as to ensure that the lower groove 123 and the two extending grooves are matched in a clamping fit mode and prevent loosening. . During installation, two ends of the air flow guide block 130 are adaptively clamped into two extension grooves (1233,1234) of the lower groove 123, and after installation, the thickness of the air flow guide block 130 is not higher than that of the atomization through hole 125 corresponding to the extension groove 1231, so that the air flow between the atomization channel 1301 and the atomization through hole 125 formed between the air flow guide block 130 and the atomization cavity 1650 can be ensured to be smooth.
As shown in fig. 7, 8, 11b and 14, in order to further fix the air flow guide block 130 in the lower groove 123 of the atomizing base 120, a fixing hole 1232 and a connecting through hole 1231 are provided at the bottom of the lower groove 123 of the atomizing base 120, and the connecting through hole 1231 and the fixing hole 1232 are disposed up and down in the longitudinal Y direction on the atomizing base 120 and are positioned on the same line. A connection hole 133 is formed at the bottom 132 of the air flow guide block 130, that is, at a side contacting the bottom surface of the lower groove 123; meanwhile, a connection member 170 is further provided, which includes an elongated connection block 171, and a connection column 173 and a fixing column 172 are provided on one side of the connection block 171 in the same direction. When in installation, the connecting post 173 of the connecting piece 170 is adaptively inserted into the connecting hole 133 of the air flow guide block 130 after passing through the connecting through hole 1231 on the atomizing base 120, so as to form tight connection; correspondingly, the fixing posts 172 of the connecting member 170 are adapted to be disposed in the fixing holes 1232 of the atomizing base 120, so as to form a tight connection, and the connecting blocks 171 of the connecting member 170 are adapted to be clamped into the clamping grooves 126 on the back side of the atomizing base 120, so that the surface of the connecting blocks 171 of the connecting member 170 and the surface of the back side of the atomizing base 120 form an integral surface.
Preferably, the connecting member 170 is made of a material having a certain elasticity and toughness, such as rubber, silica gel, etc., so that the connecting post 173 and the fixing post 172 can be designed to be interference-fit, and are tightly clamped in the connecting hole 133 and the fixing hole 1232 by the elastic restoring force of the materials, respectively. Further, in order to better clamp the connection post 173 and the fixing post 172 in the connection hole 133 and the fixing hole 1232, respectively, to avoid the loosening, the connection post 173 and the fixing post 172 may be respectively configured to have a T-shaped cross section, and the diameter of the protruding structure is slightly larger than the diameter of the connection post 173 or the fixing post 172.
Further, as shown in fig. 3 and 11 a. In order to improve the air guiding and cooling effects of the atomization channel 1301, in this embodiment, the upper surface 131 of the air guiding block 130, that is, the side surface facing the oil storage cavity 160 is designed into an arched inclined surface 131; the atomization channel 1301 formed by the gap between the arched inclined surface 131 and the heating device bracket 140 has a certain curvature, so that the distance of the atomization channel 1301 along the longitudinal Y direction is prolonged intangibly, the residence time of the atomization steam generated by the atomization cavity 1650 in the atomization channel 1301 is relatively longer, and the effect of cooling the atomization steam can be achieved; on the XY coordinate axis, the atomizing chamber 1650 and the atomizing channel 1301 are in a relative axis treatment state, so that the atomizing steam generated by the atomizing chamber 1650 can be turned along the non-right angle direction to be sent upwards into the atomizing channel 1301 along the longitudinal Y direction by the blocking and guiding action of the arched inclined surface 131, so that the effect of the discharging of the atomizing steam is avoided, wherein the atomizing steam is sent downwards into the air inlet channel formed between the air inlet hole 1210 and the atomizing chamber 1650 or the inner cavity 1211 of the atomizing seat 120 along the longitudinal Y direction.
As shown in fig. 3, 4, 7 and 8, an air suction pipe 122 is provided on the atomizing base 120 upward in the longitudinal Y direction, and the air suction pipe 122 is in air flow communication with the atomizing passage 1301 through the air guide hole 125. The nozzle base 110 is inserted on the air suction pipe 122, so that the oil storage cavity 160, the atomizing base 120 and the nozzle base 110 together form the overall structure of the electronic atomizer 100. Accordingly, the atomizing passage 1301, the air guide hole 125, the air suction passage 1221 in the air suction pipe 122, and the air discharge passage 111 in the nozzle holder 110 form an air flow through.
As shown in fig. 3, 4,6, 7 and 8, in one embodiment, a condensation chamber 124 is disposed on the atomizing base 120, and the condensation chamber 124 is located at the air outlet end of the atomizing channel 1301, that is, the air guide hole 125; accordingly, an oil absorbing medium 103 is disposed in the condensing chamber 124; the atomizing chamber 1650, the atomizing passage 1301, the oil absorbing medium 103, and the air suction pipe 122 of the atomizing base 120 are communicated with each other by air flow.
Specifically, the condensation chamber 124 is located at the upper slot position of the atomization passage 1301, that is, at the upper end in the longitudinal Y direction, according to the flow direction of the vapor after the atomization of the tobacco tar in the atomization chamber 1650; so that the condensation chamber 124 is interposed between the atomizing passage 1301 and the suction pipe 122, and an oil suction medium 103 is accommodated in the condensation chamber 124, the oil suction medium 103 can ensure air flow conduction. The atomized steam generated in the atomizing cavity 1650 sequentially passes through the atomizing channel 1301 and the air guide hole 125 and then enters the condensing cavity 124, and as the oil absorption medium 103 exists in the condensing cavity 124, the oil absorption medium 103 has a certain cooling and flow blocking effect on the high-temperature atomized steam conveyed by the atomizing channel 1301, and after being cooled, part of the atomized steam is sucked out through the air suction pipe 122 and the middle air discharge channel 111 of the suction nozzle seat 110 and is sucked by a user, so that the atomized steam in the sucked oral cavity is ensured to have proper temperature and not scald the oral cavity of the user, and the taste experience of the user is improved; the other part of the atomized steam remains in the oil absorbing medium 103 in the condensing chamber 124, is condensed by the oil absorbing medium 103, and is absorbed by the oil absorbing medium 103. Since the condensate is adsorbed by the oil suction medium 1030, there is no condensate or a very small amount of condensate in the atomized steam sucked out through the air discharge passage 111 in the suction nozzle 110; the atomized steam does not feel uncomfortable after being sucked by a user. This also greatly increases the user's experience of smoking the e-cigarette.
When the condensate absorbed by the oil absorbing medium 1030 in the condensation chamber 124 is saturated, the condensate will flow back to the atomization channel 2301 from the air guide hole 125 and finally be deposited in the lower groove 123; at this time, the fixing post 173 of the connector 170 may be pulled out of the fixing hole 1232 of the atomizing base 120, the condensate deposited in the lower groove 123 may be poured or thrown out, and then the fixing post 17 of the connector 170 may be inserted into the fixing hole 1232 of the atomizing base 120 again to be connected in a sealing manner.
Preferably, as shown in fig. 3, in order to increase the amount of "smoke" sucked by the user when sucking the electronic cigarette, an air flow hole 1030 is provided in the oil absorbing medium 103. In this way, the above-mentioned atomizing passage 1301, the air-guiding hole 125, the air-flowing hole 1030, the air-sucking passage 1221 and the air-discharging passage 111 are communicated with each other, that is, the atomized steam discharging route generated by the atomizing chamber 1650 is: c-d-e-f.
The air flow hole 1030 on the oil absorbing medium 103 may be one, and the atomization channel 1301, the air flow hole 125, the air flow hole 1030 and the air suction channel 1221 form a seamless joint with a smooth and pipeline-like channel. The atomized steam conveyed by the atomization channel 1301 has small flow blocking effect, the contact time of the atomized steam and the oil absorption medium 103 is short, and the effects of cooling and cooling the atomized steam and absorbing condensate are relatively small; the instantaneous atomization of the suction type can be relatively large; but the manufacturing cost is reduced considerably. Or alternatively
In another embodiment, the plurality of air flow holes 1030 on the oil absorbing medium 103 may be arranged in parallel side by side; at this time, the atomizing passage 1301, the air guide hole 125, the air flow through hole 1030, and the air suction passage 1221 form an air flow through; the lower interface and the upper interface of the condensation chamber 122 correspond to the connection air guide duct 125 and the suction passage 1221, respectively; by adopting the design structure, the flow blocking effect on the atomized steam conveyed by the atomizing channel 1030 is large, the contact time of the atomized steam and the oil absorption medium 1030 is relatively long, and the effects of better cooling and cooling the atomized steam and absorbing condensate are achieved; the instantaneous atomization amount during suction is relatively small, and the manufacturing cost is high.
As shown in fig. 6 and 7, in still another embodiment, in order to enhance the condensing effect on the atomized steam, the specific oil absorption surface area of the oil absorption medium 103 needs to be increased, which is generally achieved by increasing the volume of the oil absorption medium 103, and at this time, it may not be possible to completely install the condensation chamber 124 on the atomizing base 120, because the space size of the atomizing base 120 is limited, and at this time, a condensation chamber monomer 164 needs to be disposed on the oil storage chamber 160 for adapting to accommodate a portion of the oil absorption medium 103.
The oil absorbing medium 103 is a loose structure capable of absorbing substances such as liquid, grease, etc., or a structure made of any loose material, for example, food grade glass fiber, porous ceramic, porous diatomite, food grade asbestos, cotton, food grade sponge, etc.
As shown in fig. 12 and 13, in an embodiment, the sealing silica gel 104 is provided with an oil filling hole 1041, so that the atomization cavity 160 of the electronic atomizer 10 can be reused by repeatedly filling tobacco tar or atomized liquid, thereby avoiding waste caused by discarding; correspondingly, the oil filling hole 1041 is required to be sealed and blocked, at this time, a silica gel cover plate 105 adapted to seal the oil filling hole 1041 is provided, a raised rubber plug 1051 is provided on the bottom surface of the silica gel cover plate 105, and the outer diameter of the rubber plug is slightly larger than the diameter of the oil filling hole 1041; in this way, the rubber plug 1051 can be firmly plugged into the oil filler hole 1041 to prevent loosening.
It is to be understood that the foregoing description of the preferred embodiments of the invention is not to be considered as limiting the scope of the invention, which is defined by the appended claims.
