[0043] Please refer to Figure 1 , which shows the shell assembly 9 and the lower cover assembly 10 of the atomizer 100, the lower cover assembly 10 is arranged below the shell assembly 9 and connected with the shell assembly 9, and the interiors of the two form a containing space.

[0044] Please refer to Figure 2 and Figure 3 , which shows the inner support 11 and the liquid storage bin 14 of the atomizer 100, please refer to Figure 3 , which shows that the liquid storage bin 14 is arranged above the inner support 11, and the liquid storage bin 14 is used for containing aerosol substrate, please refer to Figure 2 , which shows that the inner support 11 is in a cylindrical shape.

[0045] Please refer to Figure 2 and Figure 3 , which shows the support sealing silica gel 13, the support 2, the cooperating piece 1, the atomizing core 3, the battery 4, the battery support 5 and the circuit board assembly 12. The support sealing silica gel 13 is arranged on the support 2 and sealingly cooperates with the inner circumferential side of the liquid storage bin 14, one end of the support 2 extends into the battery support 5 and is fixed on the battery support 5, the support 2 sealingly cooperates with the battery support 5, and the battery support 5 is supported on the lower cover assembly 10. The battery 4 is arranged in the battery support 5, and the battery 4 is supported on the lower cover assembly 10. The atomizing core 3 is supported on the support 2, the cooperating piece 1 is arranged on the support 2, and the cooperating piece 1 sealingly cooperates with the battery support 5. The circuit board assembly 12 is supported on the battery support 5, and the circuit board assembly 12 is electrically connected with the battery 4 and the atomizing core 3.

[0046] Please refer to Figure 5 and Figure 6 , Figure 5 A structure schematic view of the cooperating piece 1 provided for the embodiment under one viewing angle, Figure 6 A structure schematic view of the cooperating piece 1 provided for the embodiment under another viewing angle.

[0047] Please refer to Figure 5 and Figure 6 , which shows the air inlet hole 103 and the electrode insertion hole 104 arranged on the cooperating piece 1. Please refer back to Figure 3Two electrodes 6 are shown, which pass through two air inlet holes 103 on the fitting piece 1, the upper end of the electrode 6 is electrically connected with the atomization core 3, and the lower end of the electrode 6 is electrically connected with the battery 4. The battery 4 supplies power to the atomization core 3.

[0048] The aerosol substrate in the liquid storage bin 14 can flow to the atomization core 3 through the flow channel of the support 2 and the support sealing silica gel 13. Please refer to Figure 3 , the arrow shows the flow of the aerosol substrate from the liquid storage bin 14 to the atomization core 3. When the atomization core 3 is in working condition, the atomization core 3 heats the aerosol substrate to make it vaporize. When the user inhales through the nozzle of the shell assembly 9, external gas enters the shell assembly 9 and flows to the atomization core 3 through the air inlet hole 103 on the fitting piece 1. The evaporated aerosol substrate encounters the airflow to generate mist, which flows to the nozzle of the shell assembly 9 through the airflow passage on the support 2 and the liquid storage bin 14. For the airflow passage on the support 2 and the liquid storage bin 14, existing related structures can be used, and the present embodiment is not limited in detail.

[0049] In an example, please refer to Figure 5 and Figure 6 , the fitting piece 1 includes a connecting part 101 and a blocking part 102, the blocking part 102 includes a first end face 1021 and a second end face 1022, the connecting part 101 is arranged on the first end face 1021, the connecting part 101 is connected with the support 2, and the air inlet hole 103 and the electrode insertion hole 104 communicate the first end face 1021 and the second end face 1022.

[0050] In an example, please refer to Figure 5 and Figure 6 , the connecting part 101 is two, and the two connecting parts 101 are oppositely arranged.

[0051] Please refer to Figure 7 , Figure 7 for the structure diagram of the support 2 provided in the present embodiment. In Figure 7 example, the support 2 is formed with a first mounting space 201 and a second mounting space 202, and the first mounting space 201 is located between the two second mounting spaces 202. Please refer back to Figure 3 , the two connecting parts 101 are respectively inserted into the corresponding second mounting space 202 from the bottom of the support 2, and the atomization core 3 is mounted on the second mounting space 202.

[0052] Please refer to Figure 7 , the first mounting space wall surface 2011 is shown, and the two first mounting space wall surfaces 2011 are oppositely arranged. When the mist encounters a lower temperature on other cooling surfaces such as the first mounting space wall surface 2011, part of the mist will be cooled and reconverted into condensed liquid.

[0053] In an embodiment, referring to Figure 5 , the first end surface 1021 of the fitting piece 1 is provided with a boss 109, the boss 109 is located between the two connecting portions 101, and there is a spacing between the connecting portion 101 and the boss 109, and at least the air inlet hole 103 passes through the boss 109.

[0054] Referring to Figure 3 and Figure 4 , the first solution cavity 111 is schematically shown. Due to the boss 109 provided on the first end surface 1021 of the fitting piece 1, the area of the first end surface 1021 which is not provided with the boss 109 forms the first solution cavity 111 with the bracket 2, and the condensed liquid can be stored in the first solution cavity 111. Due to the air inlet hole 103 passing through the boss 109, the condensed liquid in the first solution cavity 111 is difficult to flow in the direction of the battery 4 through the air inlet hole 103, which can effectively prevent the condensed liquid from leaking to the battery or leaking to the outside of the product.

[0055] At least the air inlet hole 103 passes through the boss 109, referring to Figure 5 and Figure 6 , the air inlet hole 103 and the electrode insertion hole 104 on the fitting piece 1. In one example, only the air inlet hole 103 passes through the boss 109, while the electrode insertion hole 104 does not pass through the boss 109; in another example, not only the air inlet hole 103 passes through the boss 109, but also the electrode insertion hole 104 passes through the boss 109, referring to Figure 5 , the air inlet hole 103 and the electrode insertion hole 104 both pass through the boss 109.

[0056] In one example, the shape of the boss 109 matches the shape of the air inlet hole 103 and the electrode insertion hole 104. Specifically, referring to Figure 5 , in the example where the air inlet hole 103 is a square hole and the electrode insertion hole 104 is a circular hole, the boss 109 includes a middle region and a side region, the middle region is located between the two side regions, the shape of the middle region is square, and the shape of the two side regions is circular arc.

[0057] Regarding the height of the boss 109 protruding from the first end surface 1021, it can be reasonably set according to the spacing requirement of the atomizing core 3 and the blocking portion 102.

[0058] In this embodiment, by providing the boss 109 on the first end surface 1021, the area of the first end surface 1021 which is not provided with the boss 109 forms the first solution cavity 111 with the bracket 2, which can effectively prevent the condensed liquid from leaking to the battery or leaking to the outside of the product.

[0059] In an embodiment, the second end surface 1022 is provided with a liquid containing cavity 105, and the liquid containing cavity 105 is arranged around the air inlet hole 103. Referring to Figure 3 andFigure 4 The liquid containing cavity 105 is shown.

[0060] In an example, the side wall of the liquid containing cavity 105 along the circumferential direction is circular; in an example, the side wall of the liquid containing cavity 105 along the circumferential direction is square to match the shape of the air inlet hole 103.

[0061] When the condensed liquid flows from the first end surface 1021 to the second end surface 1022 through the air inlet hole 103, the liquid containing cavity 105 is used to contain the condensed liquid flowing over. It should be noted here that since the condensed liquid has a certain viscosity, when the condensed liquid flows to the second end surface 1022, the condensed liquid will continue to flow along the second end surface 1022 of the matching part 1, and then the condensed liquid will flow to the liquid containing cavity 105.

[0062] In this embodiment, by providing the liquid containing cavity 105 on the second end surface 1022, the liquid containing cavity 105 can be used to contain the condensed liquid flowing over, which can effectively prevent the condensed liquid from leaking to the battery cell or leaking to the outside of the product.

[0063] In an example, please refer to Figure 4 and Figure 6 The cavity wall surface of the liquid containing cavity 105 includes a first wall surface 1051, which is connected with the circumferential edge of the air inlet hole 103, please refer to Figure 4 In the direction from close to the air inlet hole 103 to far away from the air inlet hole 103, the first wall surface 1051 extends away from the center axis of the air inlet hole 103 and extends into the blocking part 102.

[0064] That is, in this embodiment, the first wall surface 1051 is like the circumferential side surface of a circular truncated cone, and the radius of one end of the first wall surface 1051 close to the air inlet hole 103 is small, and the radius of one end of the first wall surface 1051 far away from the air inlet hole 103 is large. Please refer to Figure 4 The cross section of the first wall surface 1051 is shown to be inclined.

[0065] Since the condensed liquid has a certain viscosity, when the condensed liquid flows to the second end surface 1022, the condensed liquid will continue to flow along the first wall surface 1051, please refer to Figure 4 The first wall surface 1051 extends away from the center axis of the air inlet hole 103 and extends into the blocking part 102, so that the condensed liquid climbs along the first wall surface 1051, increases the resistance of the condensed liquid flowing along the first wall surface 1051, and then to some extent prevents the condensed liquid from continuing to flow to the second end surface 1022 side through the air inlet hole 103.

[0066] That is, in the embodiment, by setting the first wall surface 1051 to extend away from the center axis of the air inlet hole 103 and toward the direction of extending into the blocking portion 102, to some extent, the condensate is prevented from continuing to flow through the air inlet hole 103 to the second end surface 1022 side, which has a certain effect on preventing the condensate from leaking to the battery cell or leaking to the outside of the product.

[0067] In one embodiment, referring to Figure 6 , the cavity wall surface of the liquid containing cavity 105 is distributed with a plurality of grooves 106. Referring to Figure 4 , Figure 4 , a view of the groove 106 in cross section is shown, Figure 4 , and Figure 6 , the first wall surface 1051 of the liquid containing cavity 105 is provided with a groove 106.

[0068] In one example, referring to Figure 6 , a plurality of grooves 106 are uniformly distributed along the circumferential square, and a plurality of grooves 106 are arranged along the direction from close to the air inlet hole 103 to away from the air inlet hole 103.

[0069] In one example, the shape of a groove 106 is circular to match the circumferential side wall of the liquid containing cavity 105.

[0070] In one example, each groove 106 has the same size on the first wall surface 1051; in another example, the grooves 106 of the same circle have the same size on the first wall surface 1051, and the size of the groove 106 on the first wall surface 1051 gradually increases along the direction from close to the air inlet hole 103 to away from the air inlet hole 103.

[0071] In one example, referring to Figure 6 , the shape of the groove 106 on the first wall surface 1051 is circular. Of course, in other examples, the shape of the groove 106 on the first wall surface 1051 can be set to be oval or square, etc.

[0072] In one example, each groove 106 has the same depth; in another example, referring to Figure 4 , the depth of the groove 106 gradually decreases along the direction from close to the air inlet hole 103 to away from the air inlet hole 103.

[0073] When the condensate continues to flow along the first wall surface 1051, due to the plurality of grooves 106 provided on the first wall surface 1051, the condensate will flow to the groove 106, thereby increasing the adsorption force of the condensate, to effectively prevent the condensate on the first wall surface 1051 from dripping down. Specifically, by setting the groove 106, the first wall surface 1051 forms a concave-convex plane, which enhances the contact area of the condensate with the first wall surface 1051 and enhances the adsorption force of the condensate.

[0074] In this embodiment, by distributing a plurality of grooves 106 on the cavity wall surface of the liquid containing cavity 105, the condensate adsorption force can be increased to effectively prevent the condensate on the first wall surface 1051 from dripping downward, which has a certain effect on preventing the condensate from leaking to the battery or leaking to the outside of the product.

[0075] In one embodiment, referring to Figure 4 and Figure 6 , a plurality of annular protrusions 107 are arranged on the cavity wall surface of the liquid containing cavity 105, and the annular protrusions 107 are sequentially sleeved from the direction close to the air inlet hole 103 to the direction away from the air inlet hole 103.

[0076] In one example, the annular protrusions 107 are continuous rings, please refer to Figure 6 , which shows that the annular protrusions 107 are continuous rings; in another example, the annular protrusions 107 are discontinuous rings, that is, it can be understood that the annular protrusions 107 include a plurality of protrusions, which are sequentially and circumferentially spaced apart. When the annular protrusions 107 include a plurality of protrusions arranged at intervals, the gap between the adjacent two protrusions is preferably staggered.

[0077] In one example, the distance between each adjacent two annular protrusions 107 is the same; in another example, the distance between each adjacent two annular protrusions 107 is not the same.

[0078] In one example, the outer contour of the cross section of the annular protrusion 107 is in the shape of a circular arc.

[0079] In one example, the shape of the annular protrusion 107 is circular to match the circumferential side wall of the liquid containing cavity 105.

[0080] When the condensate continues to flow along the first wall surface 1051 away from the air inlet hole 103, the annular protrusions 107 will hinder the flow of the condensate, that is, to a certain extent, prevent the condensate from continuing to climb up along the first wall surface 1051, increase the resistance of the condensate flowing along the first wall surface 1051, and further prevent the condensate from continuing to flow to the second end surface 1022 side through the air inlet hole 103.

[0081] When the first wall surface 1051 is also provided with grooves 106, in one example, a plurality of grooves 106 are uniformly and circumferentially spaced apart, and from the direction close to the air inlet hole 103 to the direction away from the air inlet hole 103, each groove 106 and the annular protrusion 107 are alternately distributed.

[0082] That is, in this embodiment, by arranging a plurality of annular protrusions 107 on the cavity wall surface of the liquid containing cavity 105, the condensate is prevented from continuing to flow to the second end surface 1022 side through the air inlet hole 103 to a certain extent.

[0083] In an embodiment, the cross-sectional area of each annular protrusion 107 gradually increases from a direction close to the air inlet hole 103 to a direction away from the air inlet hole 103.

[0084] The greater the cross-sectional area of the annular protrusion 107, the greater the resistance to the flow of condensate along the first wall surface 1051. By gradually increasing the cross-sectional area of each annular protrusion 107 from a direction close to the air inlet hole 103 to a direction away from the air inlet hole 103, the resistance to the flow of condensate along the first wall surface 1051 can be gradually increased.

[0085] In this embodiment, by gradually increasing the cross-sectional area of each annular protrusion 107, the greater the resistance to the flow of condensate along the first wall surface 1051, to some extent, prevents the condensate from continuing to flow through the air inlet hole 103 to the second end surface 1022 side.

[0086] In an embodiment, referring to Figure 4 and Figure 6 , the circumferential edge of the end of the air inlet hole 103 away from the connecting portion 101 is also provided with an edge block 108.

[0087] The edge block 108 cooperates with the shape of the end of the air inlet hole 103 away from the connecting portion 101, referring to Figure 6 when the shape of the end of the air inlet hole 103 away from the connecting portion 101 is square, the shape of the edge block 108 is square. Specifically, the shape of the end of the air inlet hole 103 away from the connecting portion 101 is a square with rounded corners, and the shape of the edge block 108 is a square with rounded corners.

[0088] In an example, the outer contour of the cross section of the edge block 108 is in the shape of a circular arc.

[0089] In this embodiment, by providing the edge block 108 on the circumferential edge of the end of the air inlet hole 103 away from the connecting portion 101, to some extent, prevents the condensate from continuing to flow through the air inlet hole 103 to the second end surface 1022 side.

[0090] In an embodiment, referring to Figure 3 a third liquid containing cavity 7 is formed below the blocking portion 102 between the blocking portion 102 and the battery support 5, and a liquid absorbing cotton 8 is also provided in the third liquid containing cavity 7, and the liquid absorbing cotton 8 faces the solution cavity 15. Referring to Figure 3 schematically shows the third liquid containing cavity 7 and the liquid absorbing cotton 8.

[0091] When there is a large amount of condensate flowing downward from the air inlet hole 103, the condensate flowing out of the air inlet hole 103 will directly flow to the liquid absorbing cotton 8 in the third liquid containing cavity 7; when there is too much condensate in the liquid containing cavity 105, it will also drip to the liquid absorbing cotton 8 in the third liquid containing cavity 7.

[0092] In an example, the projection of the liquid absorbing cotton 8 on the second end surface 1022 of the fitting piece 1 covers the liquid containing cavity 105, so that all the condensed liquid in the liquid containing cavity 105 drips onto the liquid absorbing cotton 8 when it drips downward.

[0093] Regarding the third liquid containing cavity 7, in a specific example, referring to Figure 8 , the battery holder 5 includes a holder main body part 501 and a partition part 502, the partition part 502 is connected to the circumferential inner side of the holder main body part 501, and the third liquid containing cavity 7 is formed between the partition part 502 and the second end surface 1022 of the fitting piece 1. The liquid absorbing cotton 8 is supported on the partition part 502. The battery 4 is arranged on the side of the partition part 502 away from the third liquid containing cavity 7. The electrode 6 passes through the partition part 502 and is connected to the battery 4. A hole is arranged on the liquid absorbing cotton 8 to avoid the electrode 6.

[0094] In this embodiment, by arranging the third liquid containing cavity 7 and the liquid absorbing cotton 8 in the third liquid containing cavity 7, the condensed liquid can be prevented from leaking to the battery or leaking to the outside of the product.

[0095] As described above, the fitting piece 1 is sealingly fitted with the battery holder 5. In an embodiment, the fitting piece 1 is made of silicone; referring to Figure 5 , the circumferential outer side of the blocking part 102 is formed with an annular sealing protrusion 110, which is deformed by extrusion to achieve the sealing fitting of the fitting piece 1 with the battery holder 5.

[0096] In this embodiment, the sealing protrusion 110 is integrally formed on the blocking part 102, which can reduce the number of parts.

[0097] In an embodiment, after the atomizer 100 works for a period of time, a large amount of condensed liquid is accumulated, which flows along the first installation space wall surface 2011 to the first solution cavity 111. When the condensed liquid flows downward along the air inlet hole 103 to the liquid containing cavity 105, the edge blocking part 108 and the annular protrusion 107 block the flow of the condensed liquid, and the first wall surface 1051 is arranged to be inclined, and the inclination can effectively block the flow of the condensed liquid. A plurality of grooves 106 are arranged on the first wall surface 1051, which are used to store the condensed liquid flowing over. Since the first wall surface 1051 is a concave-convex plane, the contact area between the condensed liquid and the first wall surface 1051 is increased, the adsorption force is enhanced, and the condensed liquid is difficult to drip into the third liquid containing cavity 7. When the liquid containing cavity 105 cannot block or store the condensed liquid, the condensed liquid flows to the third liquid containing cavity 7, and the liquid absorbing cotton 8 arranged in the third liquid containing cavity 7 can absorb the condensed liquid.

[0098] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application.
