[0042] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

Thus, the features defined as "first", "second", "third" can expressly or implicitly include at least one of the features.

For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.

[0044] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0045] The present application provides an electronic atomization device 300, see Figure 1 to Figure 2 , Figure 1 is a structural schematic diagram of an embodiment of an electronic atomization device provided by the present application, Figure 2 yes Figure 1 Schematic diagram of the cross-sectional structure of the atomizer in the electronic atomization device.

[0046] The electronic atomization device 300 can be used for atomization of liquid substrates such as nutrient solutions or liquid medicines. The electronic atomization device 300 includes an atomizer 100 and a body assembly 200 that are connected to each other, the atomizer 100 is used to store the liquid substrate and atomize the liquid substrate to form an aerosol that can be inhaled by the user, and the body assembly 200 is used to power the atomizer 100 so that the atomizer 100 can atomize the liquid substrate to form an aerosol.

[0047] The atomizer 100 includes a housing 10, an atomizer seat 20, an atomizer core 30 and a base 40. The atomizer seat 20, the atomizer core 30 and the base 40 are all assembled in the housing 10, and the atomizer core 30 is arranged between the atomizer seat 20 and the base 40, and is used to atomize the liquid matrix loaded in the housing 10.

[0048] like Figure 2 As shown, the shell 10 includes a liquid storage cavity 12 and an air guide tube 14. The air guide tube 14 is arranged in the liquid storage cavity 12, and the air guide tube 14 is connected to the closed end of the liquid storage cavity 12. A liquid storage cavity 120 is formed between the liquid storage cavity 12 and the air guide tube 14. The liquid storage cavity 120 is used to store liquid matrix, and the air guide tube 14 is used to guide the formed aerosol to the user's mouth.

[0049] The side wall of the housing 10 is provided with an air inlet 16, which is used to inhale gas outside the housing 10. In other words, the side wall of the liquid storage cavity 12 is provided with the air inlet 16, and the open end of the liquid storage cavity 12 is the open end of the housing 10. The atomizer seat 20, the atomizer core 30 and the base 40 are assembled to the housing 10 from the open end.

[0050] The atomizer seat 20 is embedded in the housing 10 from the open end of the housing 10 to block the liquid storage chamber 120, and the atomizer seat 20 is provided with an aerosol outlet 24, and the air guide tube 14 is connected to the aerosol outlet 24 to guide the aerosol generated in the atomizer seat 20 from the aerosol outlet 24 to the air guide tube 14. The side wall of the atomizer seat 20 is provided with an air inlet hole 22, and the air inlet hole 22 is connected to the air inlet hole 16.

[0051] The base 40 is provided with an air flow channel 42, which covers the open end of the housing 10, and the air flow channel 42 is connected to the air inlet 22. The external air flows through the air inlet 16, the air inlet 22 and the air flow channel 42 in sequence into the atomizer seat 20.

[0052] Optionally, the base 40 is connected to the atomizer seat 20 and covers the open end of the housing 10, and the air flow channel 42 is in fluid communication with the air inlet 22. Alternatively, the base 40 is connected to the open end of the housing 10 and covers the open end of the housing 10, the base 40 abuts against the atomizer seat 20 and the air flow channel 42 is in fluid communication with the air inlet 22.

[0053] In the existing atomizer, a vent hole is often provided in the middle of the base, and the liquid matrix leaked from the atomizer seat 20 often drips into the body assembly 200 through the vent hole, causing the body assembly 200 to malfunction.

[0054] The present application provides an air inlet 16 on the side wall of the housing 10 as the air inlet 16 of the atomizer 100, and provides an air inlet 22 on the side wall of the atomizer seat 20, and provides an air flow channel 42 on the base 40. After the atomizer seat 20 is embedded in the housing 10 from the open end of the housing 10 and the base 40 is sealed on the open end of the housing 10, the air inlet 16, the air inlet 22 and the air flow channel 42 are fluidically connected, and external gas can flow through the air inlet 16, the air inlet 22 and the air flow channel 42 in sequence. The air flow channel 42 enters the atomizer seat 20. Therefore, from the assembly position relationship between the atomizer seat 20 and the base 40 and the shell 10, it can be seen that the liquid matrix leaking from the atomizer seat 20 will find it difficult to overcome its own gravity and leak out of the atomizer 100 along the air flow channel 42, the air inlet hole 22 and the air inlet hole 16, and the leaked liquid is even less likely to leak to the main body assembly 200. Therefore, the atomizer 100 provided in the present application can effectively prevent liquid leakage and effectively reduce the failure rate of the main body assembly 200.

[0055] Combined with reference Figures 2 to 4 , Figure 4 yes Figure 2 A schematic diagram of the structure of the base in the atomizer shown.

[0056] Furthermore, the air flow channel 42 is formed with a first air hole 401 and a second air hole 402 on the base 40, and the first air hole 401 and the second air hole 402 are staggered. The air flow channel 42 includes a blocking section 420, and one end of the blocking section 420 connected to the first air hole 401 is located above the other end thereof connected to the second air hole 402; wherein the external air flows along the air flow channel 42 to the second air hole 402 through the first air hole 401.

[0057] In other words, the first vent hole 401 is in fluid communication with the air inlet 22 , the second vent hole 402 leads to the inside of the housing 10 , and the external air flows through the first vent hole 401 , the flow blocking section 420 and the second vent hole 402 to the atomizer seat 20 .

[0058] It should be noted that the end of the blocking section 420 connected to the first vent 401 is located above the end thereof connected to the second vent 402, and is limited by the side surface of the base 40 located on the open end side of the shell 10 as a reference plane. Therefore, when a user uses the electronic atomization device, even if the leaked liquid in the atomization seat 20 leaks to the second vent 402, due to the existence of the blocking section 420, the leaked liquid cannot pass through the blocking section 420 and leak out from the first vent 401.

[0059] Optionally, the airflow channel 42 is disposed inside the base 40, so that the leaked liquid will not be able to leak to the body assembly 200. Alternatively, at least part of the airflow channel 42 is exposed on the surface of the base 40, for example, part of the airflow channel 42 is leaked on its side, and when assembled on the open end of the housing 10, the inner side wall of the housing 10 or the side wall of the atomizer seat 20 covers the leaked part of the airflow channel 42, and the first vent 401 is in fluid communication with the air inlet 22; alternatively, part of the airflow channel 42 is leaked on its bottom surface, and the exposed part of the airflow channel 42 can also be covered by setting an end cap on the open end of the housing 10.

[0060] In other embodiments, the first vent hole 401 can also be directly connected to the air inlet hole 16 without the aid of the air inlet hole 22 on the atomizer seat 20 to connect to the air inlet hole 16. For example, the base 20 is embedded in the open end of the shell 10 to enable the first vent hole 401 to connect to the air inlet hole 16.

[0061] like Figure 4 As shown, in this embodiment, the base 40 includes a substrate 41 and at least one support arm 43, and the support arm 43 is arranged on one side of the substrate 41, wherein the substrate 41 is provided with a second ventilation hole 402, and at least one of the support arms 43 is provided with a first ventilation hole 401.

[0062] Optionally, one, two, three or more support arms 43 are provided on the base 41, wherein at least one support arm 43 is provided with a first vent hole 401, and when the base 40 is sealed to the open end of the shell 10, the support arm 43 can connect the first vent hole 401 to the air inlet 22.

[0063] Optionally, the first vent hole 401 may be disposed on the end surface of the support arm 43 facing away from the base 41 . Alternatively, the first vent hole 401 is disposed on the side surface of the support arm 43 .

[0064] In other embodiments, the first vent 401 and the second vent 402 may also be provided on at least one support arm 43. In other words, the first vent 401 and the second vent 402 are provided on at least one support arm 43 at the same time, and the blocking section 420 is located in the support arm 43 and connects the first vent 401 and the second vent 402.

[0065] Combined with reference Figure 2 , Figure 3 , Figure 7 and Figure 8 ,in Figure 7 yes Figure 2 The schematic diagram of the structure of the atomizer seat in the atomizer shown in FIG. Figure 8 yes Figure 7 The cross-sectional structural schematic diagram of the atomizer seat is shown.

[0066] The atomizer seat 20 includes a seat body 21 and a partition 23 arranged on the seat body 21. The partition 23 is provided with a liquid inlet hole 230. An atomizer chamber 210 is formed in the seat body 21 and on one side of the partition 23. The atomizer chamber 210 is fluidically connected to the aerosol outlet 24. The air inlet hole 22 is provided on the side wall of the seat body 21.

[0067] One side of the partition 23 is used to set the atomizing core 30, and the liquid inlet hole 230 is connected to the liquid storage chamber 120. The liquid inlet hole 230 can guide the liquid matrix stored in the liquid storage chamber 120 to the atomizing core 30. The atomizing core 30 is accommodated in the atomizing chamber 210, and the liquid inlet hole 230 guides the liquid matrix to the liquid guide surface of the atomizing core 30. The atomizing surface of the atomizing core 30 is located in the atomizing chamber 210, so as to atomize the liquid matrix in the atomizing chamber 210 to form an aerosol.

[0068] In this embodiment, the partition 23 divides the internal space of the base body 21 into a liquid inlet chamber 212 and an atomization chamber 210 . The liquid inlet chamber 212 and the atomization chamber 210 are connected through the partition 23 . The aerosol outlet 24 and the liquid inlet chamber 212 are located on the same side of the base body 21 .

[0069] Optionally, the partition 23 can also be connected to one end of the base 21 facing the liquid storage chamber 120, thereby eliminating the need to form the liquid inlet chamber 212. Alternatively, the partition 23 is connected to one end of the base 21 away from the liquid storage chamber 120, thereby eliminating the need to form the atomization chamber 210.

[0070] The number of the liquid inlet hole 230 may be one, two, three or more, and this application does not impose any specific limitation on this.

[0071] The side wall of the seat body 21 may be provided with one, two, three or more air inlet holes 22 .

[0072] Optionally, an air inlet hole 16 is provided on the side wall of the housing 10, and an air inlet hole 22 is also provided on the side wall of the seat body 21, so that when the atomizer seat 20 is embedded in the housing 10, the air inlet hole 22 is in fluid communication with the air inlet hole 16. Alternatively, two air inlet holes 16 are symmetrically provided on the side wall of the housing 10, and only one air inlet hole 22 is provided on the side wall of the seat body 21, so that the atomizer seat 20 and the housing 10 can be assembled foolproof, and when the atomizer seat 20 is embedded in the housing 10 in two different postures, the air inlet hole 22 can be in fluid communication with one of the air inlet holes 16. Alternatively, a plurality of air inlet holes 16 are symmetrically provided on the side wall of the housing 10, and a plurality of air inlet holes 22 are also provided on the side wall of the seat body 21, and the number of the air inlet holes 22 can be more than, equal to, or less than the number of the air inlet holes 16, so that the atomizer seat 20 can be embedded in the housing 10 in a variety of different postures, and at least one air inlet hole 22 is in fluid communication with at least one air inlet hole 16.

[0073] Optionally, the number of air flow channels 42 on the base 40 may be one, two, three or more, and the number of air flow channels 42 may be more than, equal to or less than the number of air inlets 22. Thus, the base 40 can cover the open end of the shell 10 in a variety of different postures, and make at least one air flow channel 42 fluidically connected to at least one air inlet 22, while also having an anti-fouling effect.

[0074] Furthermore, if Figure 8 As shown, the side wall of the seat body 21 is further provided with an assembly cavity 216, which is connected to the air inlet 22. The assembly cavity 216 is used to assemble with the base 40, so that the atomizer seat 20 can be connected to the base 40, thereby connecting the air inlet 22 and the air flow channel 42.

[0075] Specifically, refer to Figure 3 , Figure 4 and Figure 8 The assembly cavity 216 is assembled with the support arm 43 , that is, the support arm 43 is embedded in the assembly cavity 216 , and then the first vent hole 401 is fluidically connected with the air inlet hole 22 through the assembly cavity 216 , and at the same time, the base 40 can be fixed on the atomizer seat 20 .

[0076] In this embodiment, the assembly cavity 216 includes a first cavity 217 and a second cavity 218 that are connected, and the first cavity 217 and the second cavity 218 are arranged in a stepped manner, and the second cavity 218 is arranged at the top of the first cavity 217 and is connected to the air inlet 22. The first vent hole 401 is located at the end surface of the support arm 43 away from the base 41, and the support arm 43 is assembled in the first cavity 217, so that the end surface of the support arm 43 away from the base 41 faces the top of the first cavity 217, and the first vent hole 401 is connected to the second cavity 218.

[0077] The end surface of the support arm 43 facing away from the base 41 can also abut against the top of the first cavity 217 for primary sealing. The support arm 43 is also squeezed with the first cavity 217 for secondary sealing to achieve good connectivity between the air inlet 22 and the air flow channel 42 and avoid air leakage.

[0078] In other embodiments, the assembly cavity 216 may also be in a straight cylindrical shape, and the first air hole 401 is arranged on the end surface of the support arm 43 facing away from the base 41, or the first air hole 401 is arranged on the side of the support arm 43, and the support arm 43 is embedded in the assembly cavity 216, so that the first air hole 401 can be fluidically connected with the air inlet 22.

[0079] In this embodiment, the liquid storage cavity 12 is elliptical in cross section along the axis perpendicular to the air guide tube 14. The liquid storage cavity 12 is provided with air inlet holes 16 at both long axis ends of the ellipse. The atomizer seat 20 is also provided with two corresponding air inlet holes 22. Two assembly cavities 216 are provided in the side wall of the seat body 21. Two support arms 43 are connected to the side of the base 41 facing the atomizer seat 20. One of the two support arms 43 is provided with a first air vent 401, and the other support arm 43 is not provided with the first air vent 401.

[0080] The atomizer seat 20 is embedded in the shell 10, and the atomizer seat 20 and the shell 10 are guided and adapted to each other based on their own structural shapes, so that the air inlet 22 is aligned with the air inlet 16, and the two support arms 43 are arbitrarily assembled in the two assembly cavities 216, so that the first air vent 401, the air inlet 22 and the air inlet 16 can be connected, thereby achieving fool-proofing and reducing the difficulty of assembling the atomizer 100.

[0081] Combined with reference Figures 8 to 10 ,in Figure 8 yes Figure 7 The cross-sectional structural diagram of the atomizer seat is shown in FIG. Fig. 9 yes Figure 7 The axial structural diagram of the atomizer seat from one perspective is shown.

[0085] Combined with reference Figure 2 , Figure 3 and Fig.11 , Fig.11 yes Figure 2 The atomizer 100 further comprises a sealing cover 50, which is disposed on the atomizer seat 20 and is located between the atomizer seat 20 and the inner wall of the liquid storage cavity 12 to seal the gap between the atomizer seat 20 and the liquid storage cavity 12 and the air guide tube 14 to prevent leakage.

[0086] The sealing cover 50 includes a sealing side wall 51, a sealing end 52 and a surrounding wall 53. The sealing end 52 is provided with a conducting hole 520 at a position corresponding to the liquid inlet cavity 212, and a avoiding hole 522 is provided at a position corresponding to the aerosol outlet 24.

[0087] Furthermore, if Figure 7 As shown, a side wall of the seat body 21 is provided with a sink 214, and the air inlet 22 is provided at the bottom of the sink 214. The sink 214 is used to assemble a sealing component and to allow the air inlet 16 to be fluidically connected to the air inlet 22 and to avoid air leakage.

[0088] Combined with reference Figure 3 , Figure 7 and Fig.11The sealing cover 50 also includes a sealing sleeve 54 connected to the sealing side wall 51. The sealing sleeve 54 is arranged in the sink 214 to prevent air leakage by forming a gap between the side wall where the air inlet hole 22 is located and the side wall where the air inlet hole 16 is located. The sealing sleeve 54 is provided with a through hole 540, and the air inlet hole 22 is fluidically connected to the air inlet hole 16 through the through hole 540.

[0089] Combined with reference Figures 4 to 6 ,in Figure 5 yes Figure 4 The cross-sectional structure diagram of the base shown in FIG. Figure 6 yes Figure 4 A schematic diagram of the structure of the base viewed from above.

[0090] In this embodiment, the air flow channel 42 includes an air inlet section 422 and a flow blocking section 420 that are connected. The air inlet section 422 is arranged on the base 41, and the flow blocking section 420 runs through the support arm 43. The air inlet section 422 is connected to the second vent 402, and the flow blocking section 420 is connected to the first vent 401. In other words, one end of the flow blocking section 420 connected to the second vent 402 is located at the base 41, and one end of the flow blocking section 420 connected to the first vent 401 is located at the end of the support arm 43 away from the base 41, so that the leaked liquid in the atomizer seat 20 will be difficult to pass through the flow blocking section 420.

[0091] Optionally, the air inlet section 422 is located inside the base 41 , and the base 40 can prevent the leaked liquid in the atomizer seat 20 from leaking to the body assembly 200 .

[0092] In this embodiment, the second vent hole 402 passes through the base 41 , and the air inlet section 422 is disposed on a side of the base 41 away from the atomizer seat 20 .

[0093] Combined with reference Figure 2 , Figure 3 and Fig.13 , Fig.13 yes Figure 2 The atomizer 100 further includes an end cap 60 , which is disposed at the open end of the housing 10 and covers the air inlet section 422 . The end cap 60 can prevent liquid from leaking from the air inlet section 422 .

[0094] like Figures 3 to 6 As shown, a plurality of second vent holes 402 are provided in the middle of the base 41, and the plurality of second vent holes 402 are arranged directly opposite to the air guide tube 14. External gas enters the atomization chamber 210 from the middle of the base 41, flows through the atomization core 30, carries away the aerosol formed after the liquid matrix is ​​atomized, and enters the user's oral cavity through the air guide tube 14, which can ensure the atomization efficiency and taste. The plurality of second vent holes 402 are connected to the air inlet section 422, and the aperture of the second vent holes 402 is small. The leaked liquid can form a liquid film on the surface of the second vent holes 402, thereby preventing the leaked liquid from leaking to the second vent holes 402.

[0095] like Figure 3 As shown, in this embodiment, the end cover 60 is connected to the open end of the housing 10 and covers the base 40 , which can prevent the leaked liquid in the atomizer seat 20 from leaking to the main body assembly 200 .

[0096] Optionally, the end cover 60 may also be connected to the base 40 and cover the air inlet section 422 , and may also prevent the leaked liquid in the atomizer seat 20 from leaking to the main body assembly 200 .

[0097] Furthermore, the main body assembly 200 is provided with an airflow detection component, which may be a microphone or the like, which detects the change in the airflow state in the airflow channel 42 caused by the user's puffing action to trigger the controller in the main body assembly to power on or off the atomizer 100.

[0098] like Figure 6 As shown, the base 41 is further provided with an air guide section 424, which is connected to the flow blocking section 420, and is used to lead to the airflow detection component in the body component 200. The air guide section 424 is spaced apart from the second vent hole 402 and is on the same side as the air inlet section 422. The end cover 60 is further provided with a through hole 62. When the end cover 60 is connected to the open end of the housing 10, the through hole 62 is fluidically connected to the air guide section 424 to lead to the airflow detection component on the body component 200 through the through hole 62.

[0099] Among them, the cross-sectional dimension of the air guide segment 424 along the extension direction is smaller than the cross-sectional dimension of the air inlet segment 422 along the extension direction, and the surface of the air guide segment 424 has a strong surface tension to liquids, etc., so that the leaked liquid entering the second air vent 402 is difficult to enter the air guide segment 424 even if it enters the air inlet segment 422, thereby preventing the leaked liquid from leaking to the main body component 200 through the air guide segment 424 and the via 62.

[0100] Optionally, the air guiding section 424 may also be partially disposed inside the base 41, and one end of the air guiding section 424 connected to the flow blocking section 420 is located inside the base 41, so that a height difference is formed between one end of the air guiding section 424 connected to the flow blocking section 420 and one end of the air inlet section 422 connected to the flow blocking section 420, so as to prevent liquid leakage from entering the air guiding section 424.

[0101] like Fig.13 As shown, specifically, the end cover 60 includes a cover body 61 and an annular wall 63, the annular wall 63 is arranged at the outer edge of the cover body 61, and the annular wall 63 is provided with a snap-fit ​​structure connected to the outer wall of the liquid storage cavity 12, and the snap-fit ​​structure can be a snap-fit ​​interface or a snap-fit ​​protrusion, etc., and a through hole 62 is provided on the cover body 61, and the cover body 61 is used to seal the side of the base 41 away from the atomizer seat 20, and then seal the air inlet section 422 and the air guide section 424, and the air guide section 424 can only be connected to the airflow detection component in the main body assembly 200 through the through hole 62 fluid.

[0102] Combined with reference Figure 3 , Figure 4 and Fig.13 The atomizer 100 further includes an electrode 70. An electrode hole 410 is provided on the base 41. A through hole 610 corresponding to the electrode hole 410 is provided on the cover 61. The electrode 70 is connected to the electrode hole 410 and is electrically connected to a power source on the body assembly 100 through the through hole 610. The electrode 70 is also electrically connected to the atomizer core 30 in the atomizer seat 20 to supply power to the atomizer core 30.

[0103] Specifically, Figure 4 and Figure 5 As shown, the base 41 includes a base 412 and an annular wall 414 arranged on one side of the base 412, the annular wall 414 cooperates with the base 412 to form a accommodating cavity 416, the second vent hole 402 is arranged on the base 412 and connected to the accommodating cavity 416, the support arm 43 is connected to the base 412 and is arranged in the accommodating cavity 416, and a space for plug-in is formed between the support arm 43 and the annular wall 414.

[0104] like Figure 7 As shown, an end of the seat body 21 away from the aerosol outlet 24 is further provided with an inserting portion 219 . The inserting portion 219 is inserted into the inserting space between the support arm 43 and the annular wall 414 , so that the atomizing cavity 210 is connected to the accommodating cavity 416 .

[0105] In other words, if Figure 3 As shown, the base 40 also covers one end of the atomizer seat 20 away from the liquid storage chamber 120, and at least a portion of the base 40 is accommodated in the atomizer seat 20, for example, the support arm 43 is assembled with the assembly cavity 216, and the second sub-arm 432 is located in the atomizer cavity 210 to cooperate with the partition plate 23 to clamp and fix the atomizer core 30.

[0106] Combined with reference Figures 3 to 5 The outer side of the annular wall 414 is provided with a convex sealing rib 415 . The annular wall 414 is sandwiched between the atomizer seat 20 and the inner wall of the liquid storage cavity 12 . The sealing rib 415 is used to seal the gap between the annular wall 414 and the inner wall of the liquid storage cavity 12 .

[0107] The base 40 is connected to the atomizer seat 20 and covers one end of the atomizer seat 20 away from the liquid storage chamber 120 , so that all the leaked liquid is gathered in the accommodating chamber 416 to avoid leaking to the main assembly 200 .

[0108] Furthermore, if Figure 4 As shown, the base 412 is provided with a liquid collecting groove 417 around the electrode hole 410 and the second ventilation hole 402 , and the liquid collecting groove 417 is used to collect the leaked liquid, etc., to prevent the leaked liquid from soaking the electrode 40 and to reduce the leaked liquid from entering the second ventilation hole 402 .

[0109] like Figure 7and Figure 8 As shown, an aerosol flow channel 240 is opened on the outer side of the side wall of the seat body 21, and the aerosol flow channel 240 connects the atomization chamber 210 and the aerosol outlet 24. A plurality of first condensation grooves 241 are provided on the outer side of the side wall of the seat body 21, and the plurality of first condensation grooves 241 are distributed on both sides of the aerosol flow channel 240. A second condensation groove 242 is also provided on the inner side wall of the atomization chamber 210.

[0110] The first condensation tank 241 and the second condensation tank 242 are used to gather and condense small droplets that are not fully atomized in the aerosol to improve the purity of the aerosol, so that the user can get a better taste.

[0111] The plurality of first condensation grooves 241 are arranged in parallel along the direction of the base 40 toward the liquid storage chamber 120 to fully condense the small droplets flowing with the aerosol through the aerosol flow channel 240. The plurality of second condensation grooves 242 are vertically arranged on the inner wall of the atomization chamber 210 to guide the condensed small droplets to the liquid collection tank 417.

[0112] See also Figure 2 and Figure 3 In this embodiment, a sealing member 55 is further provided between the partition plate 23 and the atomizer core 30 , and the sealing member 55 is used to seal the gap between the partition plate 23 and the atomizer core 30 .

[0113] Optionally, the seal 55 is a sealing gasket, which is disposed between the end surface of the atomizer core 30 and the lower surface of the partition 23. Alternatively, the seal 55 is in the shape of a cap, which can be sleeved on one end of the atomizer core 30 and located between the atomizer core 30 and the lower surface of the partition 23 and the inner side wall of the atomizer chamber 210.

[0114] Further, see Figure 3 , Fig. 9 and Fig.10 A ventilation groove 232 is provided on the partition plate 23 and / or the sealing member 55 , and the ventilation groove 232 communicates with the liquid storage chamber 120 and the atomizing chamber 210 to adaptively adjust the air pressure in the atomizing chamber 210 .

[0115] For example, when the liquid matrix in the liquid storage chamber 120 is consumed, if the liquid storage chamber 120 cannot be replenished with gas, the gas pressure in the liquid storage chamber 120 will continue to decrease. When the gas pressure in the chamber decreases to a certain extent, the liquid matrix will not flow smoothly, resulting in insufficient liquid supply to the atomizer core 30, which is prone to produce a burnt smell and reduce the atomization efficiency, ultimately giving the user a bad suction experience. Alternatively, when the atomizer core 30 atomizes the liquid matrix, the air in the liquid storage chamber 120 is heated, causing the gas pressure in the chamber to increase, and the excessive gas pressure in the liquid storage chamber 120 may cause the liquid matrix to leak outward, and these factors will increase the failure rate of the electronic atomization device 300.

[0116] The ventilation groove 232 connects the liquid storage chamber 120 and the atomizing chamber 210, and then connects to the external atmosphere through the atomizing chamber 210. The external gas can enter the liquid storage chamber 120 through the ventilation groove 232 to increase the air pressure in the liquid storage chamber 120. The liquid matrix in the liquid storage chamber 120 can also enter the ventilation groove 232, and by adaptively adjusting the amount of liquid matrix entering the ventilation groove 232, the air pressure balance in the liquid storage chamber 120 can be maintained, thereby avoiding the occurrence of poor liquid discharge and leakage of the atomizer 100, thereby improving the quality of the atomizer 100.

[0117] In this embodiment, Figures 8 to 10 As shown, a ventilation groove 232 is provided on one side of the partition 23 facing the atomizing chamber 210, and the ventilation groove 232 connects the liquid inlet hole 230 and the atomizing chamber 210. The sealing member 55 covers the ventilation groove 232 so that one end of the ventilation groove 232 connects to the liquid inlet hole 230 and the other end thereof connects to the atomizing chamber 210.

[0118] The ventilation groove 232 can be arranged in a circuitous manner on the partition 23 to increase the length of the ventilation groove 232 itself and increase the space for storing liquid matrix. The ventilation groove 232 can also be arranged in a straight line, as long as the ventilation groove 232 can connect the liquid inlet hole 230 and the atomization chamber 210, and this application does not limit this.

[0119] The ventilation grooves 232 may also be provided in multiple numbers, and the multiple ventilation grooves 232 may increase the regulating rate of the air pressure in the liquid storage chamber 120. The multiple ventilation grooves 232 may be ventilated at the same time to quickly increase the air pressure in the liquid storage chamber 12, and the multiple ventilation grooves 26 may also be filled with liquid at the same time to quickly reduce the air pressure in the liquid storage chamber 12. The ventilation groove 232 may also be provided in one number, and the present application does not limit the number of ventilation grooves 232.

[0120] Furthermore, a buffer groove 234 is further provided on the side of the partition 23 away from the liquid storage cavity 12. The ventilation groove 232 flows through the buffer groove 234. The cross-sectional area of ​​the buffer groove 234 along the path direction of the ventilation groove 232 is larger than the cross-sectional area of ​​the ventilation groove 232 in the same direction. The buffer groove 234 is used to buffer the liquid matrix. The buffer groove 234 can accommodate more liquid matrix, thereby improving the liquid storage capacity of the ventilation groove 232 to prevent the liquid matrix from leaking from the ventilation groove 232.

[0121] After research, it was found that the depth of the ventilation groove 232 should be set to 0.1mm to 0.5mm, the width of the ventilation groove 232 in a direction perpendicular to its path direction should be set to 0.1mm to 0.5mm, and the width of the cache groove 234 should be greater than or equal to the width of the ventilation groove 232, and the depth of the cache groove 234 should be greater than the depth of the ventilation groove 232.

[0122] When the cross-sectional dimension of the ventilation groove 232 perpendicular to the path direction is within the above-mentioned dimension range, the ventilation can be smooth, and the surface adsorption force of the ventilation groove 232 on the liquid matrix is ​​appropriate, so that the liquid matrix in the liquid storage chamber 120 can be well regulated in the ventilation groove 232 and is not easy to leak. When the depth of the ventilation groove 232 is less than 0.1 mm or the width of the ventilation groove 232 is less than 0.1 mm, the adsorption force of the ventilation groove 232 on the liquid matrix is ​​too large, making ventilation difficult and not conducive to the air pressure regulation in the liquid storage chamber 120. When the depth of the ventilation groove 232 is greater than 0.5 mm or the width of the ventilation groove 232 is greater than 0.5 mm, the adsorption force of the ventilation groove 232 on the liquid matrix is ​​too small, and the ventilation groove 232 is easy to cause liquid matrix leakage.

[0123] In this embodiment, two ventilation grooves 232 are provided on the partition plate 23. The two ventilation grooves 232 are adjacent to each other end to end and are arranged around the liquid inlet 230, so that the ventilation grooves 232 can have a longer length, can store more liquid matrix, and make the air pressure in the liquid storage chamber 12 more adjustable. The ports communicating with the ventilation grooves 232 and the liquid inlet 230 are arranged in different positions, which can prevent the bubbles generated by the two ports at the same place from aggregating and increasing the difficulty of liquid matrix down.

[0124] like Figure 3 and Fig.12 As shown, the sealing member 55 includes a sealing ring gasket 550 and two isolation gaskets 552 respectively arranged at opposite ends of the sealing ring gasket 550. The sealing ring gasket 550 is provided with an opening 554 corresponding to the liquid inlet hole 230. The isolation gasket 552 is used to press against the inner wall of the atomizing chamber 210, so that a gap is reserved between the sealing ring gasket 550 and the inner wall of the atomizing chamber 210, so that the ventilation groove 232 is connected to the atomizing chamber 210 through the gap.

[0125] Further, see again Fig. 9 and Fig.10 The inner wall of the atomizing chamber 210 is further provided with a guide groove 211, which is connected to the ventilation groove 232, so that even if a small amount of liquid matrix leaks out along the ventilation groove 232, the leaked liquid matrix can be gathered along the guide groove 211 and the liquid guide groove 434 to the liquid collecting groove 417 to avoid random splashing of the leaked liquid.

[0126] Optionally, the seal 55 may be provided with the ventilation groove 232 and the buffer groove 234, while the partition 23 is not provided with the ventilation groove 232 and the buffer groove 234. Alternatively, the partition 23 and the seal 55 are both provided with partial ventilation grooves 232 and the buffer groove 234, and the partition 23 and the seal 55 cooperate with each other to form the ventilation groove 232 and the buffer groove 234, which is not specifically limited in the present application.

[0127] Different from the prior art, the present application discloses an electronic atomization device and an atomizer thereof. An air inlet is provided on the shell, an air flow channel is provided on the base, and the base is sealed on the open end of the shell, and the air flow channel is formed with a first air vent and a second air vent on the base, and the air flow channel includes a flow blocking section, and one end of the flow blocking section connected to the first air vent is located above the end thereof connected to the second air vent, the first air vent is connected to the air inlet, and the second air vent leads to the shell. Due to the existence of the flow blocking section, even if there is leakage in the shell, it cannot pass through the flow blocking section and leak out through the first air vent, and the air inlet on the shell is connected to the external atmosphere, and the leakage is even less likely to leak to the main body component, so the atomizer provided by the present application can effectively prevent leakage and effectively reduce the failure rate caused by it to the main body component.

Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
