An embodiment of the present invention provides an electronic atomization device, which includes an atomizer and a power supply, where the power supply is used to supply power to the atomizer, so that the atomizer can heat liquid such as flowers, leaves, herbs, etc. to atomize and form gas. The power source may be selected from the prior art.

Referring to fig. 1 to 8, an atomizer according to an embodiment of the present invention includes a main body 100, and a heat generating top cover 200 and a heat generating body 300 connected to each other and disposed in the main body 100.

The main body 100 has a main air passage 110, and the main air passage 110 communicates with the outside atmosphere. Main air passage 110 is configured to output atomized aerosol, which in turn may be directed into the mouth of a user. In the embodiment shown in fig. 1 and 4, the main body 100 includes a hollow first housing 120 and a hollow second housing 130. The first housing 120 is at least partially located within the second housing 130. Alternatively, the first housing 120 and the second housing 130 may be integrally formed, or may be separately formed and assembled into an integral structure. The hollow portion of the first casing 120 forms the aforementioned main air passage 110. A reservoir 140 for storing liquid is formed between the first housing 120 and the second housing 130. A liquid outlet 141 is arranged at one side of the liquid storage bin 140, and the liquid in the liquid storage bin 140 can flow out from the liquid outlet 141.

The heating element 300 has a heating surface 310, and the heating surface 310 is provided with a heating core, which can be electrically connected with a power supply, so that when the power supply supplies power, the heating core generates heat to atomize the liquid permeating to the heating surface.

The heat generating top cap 200 has a liquid passing channel 260 (shown in fig. 7), and one side of the liquid passing channel 260 has a liquid inlet 250 corresponding to the liquid outlet 141, so that the liquid can flow into the liquid inlet 250 along the liquid outlet 141 and enter the liquid passing channel 260. The other side of the liquid passing passage 260 communicates with a side of the heat generating body 300 away from the heat generating surface 310 to allow the liquid to contact the heat generating body 300. When the liquid is atomized, the liquid enters the liquid passing channel 260 from the liquid storage bin 140 and enters the heating element 300, and then the liquid is atomized to form gas under the heating of the heating surface 310 of the heating element 300.

As shown in fig. 1, a cap air passage 210 is formed between the heat generating cap 200 and the inner wall of the main body 100. The heat generating cap 200 has an air channel corner 220, and the cap air channel 210 communicates with the main air channel 110 through the aforementioned air channel corner 220. In the illustrated embodiment, the heat generating top cover 200 may be U-like shaped. One side of the heating top cover 200 can be provided with two liquid inlets 250 at intervals; the side middle of the heat generating top cover 200 forms a recess 201 along the direction close to the heat generating body 300 (i.e. the direction of the Z axis in the figure), and the recess 201 and the main body 100 have a gap therebetween, forming the air duct corner 220, and the air duct corner 220 is communicated with the main air duct 110. The aforementioned cap air passage 210 may be formed between the side wall of the heat generating cap 200 and the second housing 130 of the main body 100. Liquid formed by condensation of the gas in the top cap gas channels 210 (i.e., condensate) may flow back to the gas channel corners 220. The shape and structure of the cap air channel 210 are not particularly limited, and may be selected according to actual conditions.

The liquid entering the liquid passage 260 from the liquid storage bin 140 is atomized to obtain gas under the heating action of the heating element 300. As shown by the arrows in fig. 4, the gas enters main airway 110 along top airway 210 through airway corners 220 and moves outside main body 100 for the user to inhale. During this process, part of the atomizing gas may be reduced in temperature and liquefied during the movement, forming a condensate. As shown by the arrows in fig. 5, the coolant flows back along the inner wall of the main duct 110 (i.e., the inner wall of the first casing 120) to the duct corner 220. Since the height of the recess 201 of the heat generation top cover 200 is lower than the height of the other portions of the heat generation top cover 200 in the vertical direction (i.e., the Z-axis direction in fig. 1 to 5); thus, liquid may accumulate at the airway corner 220. And along with the atomizer constantly atomizes, accumulated liquid is probably discharged by main air duct 110 under the drive of air current when the suction, leads to the condition of weeping to lead to the atomizer to prevent that the suction weeping reliability is poor.

In some embodiments, as shown in fig. 1-8, a liquid return groove 230 extending to the heating element 300 is provided at the corner 220 of the air passage to improve reliability of the atomizer against leakage of liquid during suction. Wherein, the liquid returning groove 230 can return the liquid accumulated at the corner 220 of the gas supply channel to the heating element 300. That is, the aforementioned liquid returning tank 230 is provided in the recess 201 of the heat generating top cover 200, and one side of the liquid returning tank 230 communicates with the heat generating body 300 so that the liquid can flow to the heat generating body 300 along the liquid returning tank 230 as shown by arrows in fig. 2 and 3. The liquid may move inside the heating element 300 on the surface of the heating element 300, or the liquid may be secondarily atomized on the surface of the heating element 300 to form an atomized gas. It is easy to understand that the heating element 300 may be made of porous ceramic or porous metal, and the material is not limited to the above material, and the heating element 300 may be made of a material that realizes secondary atomization after the liquid contacts the surface of the heating element 300.

For convenience of description, the depth direction of the liquid returning tank 230 is defined as the depth direction of the liquid returning tank 230 (X-axis direction in fig. 1 to 4), the direction of the liquid returning tank 230 from the heat generating top cover 200 to the heat generating surface 310 of the heat generating body 300 is defined as the longitudinal direction of the liquid returning tank 230 (Z-axis direction in fig. 1 to 5), and the direction perpendicular to both the longitudinal direction and the depth direction is defined as the width direction of the liquid returning tank 230 (Y-axis direction in fig. 1 to 5).

The shape and size of the liquid returning groove 230 can be adjusted according to actual conditions. In the illustrated embodiment, the liquid return grooves 230 are each rectangular or cuboid-like in shape.

In some embodiments, the liquid returning tank 230 is disposed at a side of the heat generating top cover 200 close to the heat generating body 300. The surface of the heat generating body 300 may be exposed from the liquid return groove 230 to the air passage corner 220.

As shown in fig. 1-8, the liquid returning groove 230 is formed by enclosing a bottom wall 231 and a groove side wall.

Wherein the bottom wall 231 (shown in fig. 6-8) is located on the side of the liquid returning tank 230 in the depth direction and near the heat generating body. The bottom wall 231 of the liquid returning groove 230 penetrates through the heat generating top cover 200, so that the liquid returning groove 230 forms a through hole along the X-axis direction.

As shown in fig. 5 and 6, the trough side walls may include a first side wall 233, a second side wall 234, a third side wall 235, and a fourth side wall 236 connected end to end. The first side wall 233 and the third side wall 235 are disposed opposite to each other along the length direction (Z-axis direction) of the liquid returning groove 230, the first side wall 233 is located on the side away from the heat generating surface 310, the third side wall 235 is located on the side close to the heat generating surface 310, and the second side wall 234 and the fourth side wall 236 are disposed opposite to each other along the width direction (Y-axis direction) of the liquid returning groove 230.

In some embodiments, as shown in fig. 1-3, the tank side walls of the liquid return tank 230 have side wall openings 232, the side wall openings 232 for the passage of liquid.

For example, in some embodiments, the third sidewall 235 of the liquid returning tank 230 is provided with at least one sidewall opening 232, and the liquid can flow along the length direction (Z-axis direction) of the liquid returning tank 230 to flow to the heating element 300 for secondary atomization; the liquid may also move in the depth direction (X-axis direction) of the liquid returning tank 230 so as to be adsorbed on the surface of the heat-generating body 300 for secondary atomization.

For another example, in other embodiments, at least one of the second side wall 234 and the fourth side wall 236 of the liquid returning groove 230 and the third side wall 235 are provided with the side wall opening 232, and the liquid can flow along any one of the side wall openings 232 to the surface of the heating element 300, so as to perform secondary atomization.

As shown in fig. 4, in other embodiments, none of the side walls of the liquid returning tank 230 has a side wall opening, and the liquid moves in the depth direction (X-axis direction) of the liquid returning tank 230 so as to be adsorbed on the surface of the heat-generating body 300 for secondary atomization.

In some embodiments, as shown in FIG. 6, at least one of the tank side walls of the flashback tank 230 is provided with a chamfer 237. The slope 237 may guide the liquid to flow to the heat-generating body 300. The inclined surface 237 is gradually close to the heat-generating body 300 in the moving direction of the liquid. That is, the inclined surface 237 is gradually close to the heat-generating body 300 in the direction from the side wall of the groove to the middle of the groove. The angle of inclination of the ramp 237 may be adjusted to suit the situation.

For example, in some embodiments, the side wall of the return slot 230 away from the heat-generating surface 310 along the length direction thereof is provided with an inclined surface 237, that is, the first side wall 233 of the return slot 230 is provided with an inclined surface 237. The inclined surface 237 is gradually close to the heat-generating body 300 in the direction from the first side wall 233 to the third side wall 235. The liquid can flow along the inclined plane 237 provided on the first groove wall 233, through the liquid returning groove 230, and to the surface of the heat-generating body 300.

For another example, in other embodiments, the first slot wall 233, the second slot wall 234, and the fourth slot wall 236 of the liquid return slot 230 are all provided with a slope 237 to facilitate the liquid to flow into the liquid return slot 230.

In some embodiments, the thickness of the tank sidewall of the liquid return tank 230 gradually decreases along the length of the liquid return tank 230. In other embodiments, the thickness of the tank sidewall of the liquid return tank 230 is constant along the length of the liquid return tank 230.

In some embodiments, the bottom wall 231 of the liquid returning tank 230 interferes with the heat-generating body 300 in the depth direction of the liquid returning tank 230.

In other embodiments, the bottom wall 231 of the liquid returning groove 230 may have a certain gap with the side wall of the heat-generating body 300. It should be noted here that the width of the gap in the depth direction of the return tank 230 cannot be too large, and it is necessary to satisfy that the surface of the liquid flowing to the tank bottom wall 231 of the return tank 230 can touch the surface of the heating body 300 so that the liquid can be secondarily atomized.

The number of the liquid returning grooves 230 may be one or more.

For convenience of description, the total width length of the heat-generating top cover 200 in the width direction of the liquid return tank 230 is defined as D, the portion of the heat-generating top cover 200 located at 0.25D to 0.75D (inclusive) is defined as the middle portion of the heat-generating top cover 200, and the portion of the heat-generating top cover 200 located at 0 to 0.25D (exclusive) or 0.75D to D (exclusive) is defined as the edge of the heat-generating top cover 200.

For example, in some embodiments, the number of the liquid returning grooves 230 is one, and the liquid returning grooves 230 are located in the middle of the heat generating top cover 200 in the width direction of the liquid returning grooves 230.

For another example, in other embodiments, the number of the liquid returning grooves 230 is two or more, and the liquid returning grooves 230 are disposed at intervals on the heat generating top cover 200.

In some embodiments, each of the liquid returning grooves 230 is spaced apart in the width direction thereof. The widths of the spaces between adjacent liquid return grooves 230 may be the same, partially the same, or completely different.

For example, in one embodiment, the fluid return slots 230 are equally spaced.

For another example, in another embodiment, the number of the liquid returning grooves 230 is plural, and along the width direction of the liquid returning grooves 230, the number of the liquid returning grooves 230 located in the middle of the heat-generating top cover 200 is M (M is a positive integer), the number of the liquid returning grooves 230 located at the edge of the heat-generating top cover 200 is N (N is a positive integer), and M is greater than or equal to N.

In some embodiments, the liquid returning groove 230 may be provided with one or more rows along the length direction thereof, and each row includes a plurality of liquid returning grooves 230.

For example, in the illustrated embodiment, the return tanks 230 are arranged in a row.

For another example, in other embodiments, the liquid return slots 230 may be arranged in a plurality of rows, and adjacent rows of liquid return slots 230 may be equidistant, partially equidistant, or not equidistant at all. Furthermore, the return liquid tanks 230 of each row may not be completely, partially or completely located at the same horizontal position.

Further, in the case where a plurality of liquid returning grooves 230 are provided, the length and width of each liquid returning groove 230 may be completely uniform, partially uniform, or completely non-uniform.

For example, in one embodiment, the length and width of each liquid returning groove 230 are the same, and are arranged at equal intervals.

For another example, in one embodiment, the length and the width of each liquid returning groove 230 are different, each liquid returning groove 230 is arranged at equal intervals, and in the width direction of the liquid returning groove 230, the width of the liquid returning groove 230 in the middle of the heat-generating top cover 200 is larger than the width of the liquid returning groove 230 at the edge of the heat-generating top cover 200, and the length of the liquid returning groove 230 in the middle of the heat-generating top cover 200 is smaller than the length of the liquid returning groove 230 at the edge of the heat-generating top cover 200.

For another example, in one embodiment, the lengths of the liquid returning grooves 230 are different, the widths of the liquid returning grooves 230 are the same, the liquid returning grooves 230 are arranged at intervals, and the length of the liquid returning groove 230 located in the middle of the heat-generating top cover 200 is shorter than the length of the liquid returning groove 230 located at the edge of the heat-generating top cover 200 along the width direction of the liquid returning groove 230.

It should be noted here that, no matter the length of the liquid returning groove 230 is larger or smaller, the bottom of the liquid returning groove 230 is entirely or partially exposed from the side wall of the heating element 300, i.e. the liquid returning groove 230 can supply the liquid to return to the heating element 300 from the air channel corner 220.

In an embodiment, the liquid returning groove 230 may be disposed on two opposite sidewalls of the heat generating top cover 200 in a depth direction of the liquid returning groove 230. In other embodiments, the liquid returning groove 230 may be disposed on only one sidewall of the heat-generating top cover 200.

As shown in fig. 1, 2, 6 and 7, the heat generating top cover 200 is provided with a guide groove 240. One side of the guiding groove 240 is located at or near the recess 201, and the other side of the guiding groove 240 is located at one side of the heat generating top cover 200 near the heat generating surface 310. The sidewalls of the guiding groove 240 may partially protrude from the outer surface of the heat generating top cap 200, or may be flush with the outer surface of the heat generating top cap 200.

For example, in the illustrated embodiment, the heat generating top cover 200 is provided with a convex strip 241. The protruding strips 241 are disposed along the longitudinal direction of the liquid returning groove 230. The number of the convex strips 241 is plural, and the convex strips 241 are arranged at intervals. The flow guide grooves 240 are formed between adjacent convex strips 241.

As shown by the arrow in fig. 2, the diversion trench 240 is communicated with the liquid returning trench 230, so that the liquid accumulated at the air duct corner 220 flows to the liquid returning trench 230 along the diversion trench 240 and then enters the heating element 300. In addition, the diversion trench 240 may be configured to allow the liquid to flow more intensively along a specific line to the liquid returning trench 230. That is, under the action of the diversion trench 240, most of the liquid flows along the diversion trench 240 to the liquid returning trench 230, so as to facilitate the secondary atomization. And a small amount of liquid may flow to the heat-generating body 300 along the portion of the heat-generating top cover 200 where the guide groove 240 is not provided.

In some embodiments, a side of diversion trench 240 away from main airway 110 communicates with fluid return trench 230. In other embodiments, the middle of the diversion trench 240 is in communication with the fluid return trench 230. The position of the liquid returning groove 230 relative to the flow guide groove 240 can be adjusted according to actual conditions.

As shown in fig. 2-7, in some embodiments, the recess 201 of the heat generating top cover 200 may further be provided with a protrusion 270, and the protrusion 270 and the heat generating top cover 200 may be integrally formed, or other connection manners may be selected. The protrusion 270 extends in the direction of the main air passage 110. The connection between the protrusion 270 and the recess 201 of the heat-generating top cover 200 may be provided with a flange 271, and the surface of the flange 271 may be an inclined plane or an inclined curved surface, so that the liquid flows from the recess 201 to the liquid return groove 230 along the surface of the flange 271. The provision of the raised portion 270 may reduce the depth of the depression 201 to reduce the maximum accumulation of accumulated liquid without affecting the ventilation of the airway corner 220.

In the present invention, the liquid returning groove 230 is provided on the heat generating top cover 200, so that the liquid accumulated at the air passage corner 220 can flow back to the heat generating body 300 along the depth direction of the liquid returning groove 230 for secondary atomization. Meanwhile, the arrangement can reduce the liquid leakage condition from the main air passage 110 to the atomizer, and effectively improves the liquid leakage prevention performance of the atomizer and the electronic atomization device.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the utility model. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
