[0024] It should be noted that, unless otherwise specified, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed descriptions in the specific implementation should be understood as explanations of the purpose of this application and should not be regarded as undue limitations on this application.

[0025] In the description of the embodiments of this application, it should be noted that the terms "top," "bottom," and "height direction," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 The orientations or positional relationships shown are for the convenience of describing the embodiments of this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the embodiments of this application. The application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0026] like Figure 1 As shown, this application provides an aerosol generating device 1000, which includes an atomizer 100 and a power supply assembly 200 according to any embodiment of this application.

[0027] The aerosol generating device 1000 is used to atomize an aerosol generating matrix to generate aerosols for user use. The aerosol generating matrix includes, but is not limited to, pharmaceuticals, nicotine-containing materials, or nicotine-free materials. In embodiments of this application, the aerosol generating matrix may, for example, be a liquid material made primarily of plants (e.g., tobacco) with added aerosol forming agents and aroma materials.

[0028] The power supply assembly 200 is electrically connected to the atomizer 100. The power supply assembly 200 is mainly used to supply power to the atomizer 100 and to control the opening and closing of the entire aerosol generating device 1000.

[0029] In some embodiments, the atomizer 100 and the power supply can be mechanically and electrically connected together axially. Further, the atomizer 100 and the power supply can be detachably connected in any direction via magnetic connection, threaded connection, snap-fit ​​connection, or other detachable methods. Both the atomizer 100 and the power supply can be replaced or upgraded individually, reducing replacement costs and saving user expenses. Of course, in other embodiments, the atomizer 100 and the power supply can also be non-detachably connected.

[0030] Furthermore, the atomizer 100 and / or power supply are not limited to being cylindrical; they can also be other shapes such as elliptical or square cylindrical.

[0031] Those skilled in the art will understand that the embodiments of this application do not specifically limit the type of aerosol generating device 1000. For example, the aerosol generating device 1000 may be a medical nebulizer, an air humidifier, or an electronic cigarette, or any device that requires the use of a nebulizer 100.

[0032] like Figures 2 to 4 As shown, this application embodiment provides an atomizer 100. The atomizer 100 includes an atomizing component 20 and an air outlet channel 30a. The atomizing component 20 includes a substrate 21, which includes a first surface 21a and a second surface 21b disposed opposite to each other, with the first surface 21a facing the air outlet channel 30a. The substrate 21 also has at least one through hole 21c, with both ends of the through hole 21c penetrating the first surface 21a and the second surface 21b respectively, allowing external air to enter the air outlet channel 30a through the through hole 21c.

[0033] For example, please refer to Figure 1 and Figure 2 The atomizer 100 includes a housing assembly 30, and an air outlet channel 30a is formed inside the housing assembly 30, which extends along the height direction of the atomizer 100.

[0034] The housing assembly 30 is the outer housing of the atomizer 100. An air outlet channel 30a is formed inside the housing assembly 30, and the aerosol can be discharged from the air outlet of the air outlet channel 30a for user use.

[0035] The air outlet passage 30a can be located in the middle region within the housing assembly 30, or it can be located on the side of the middle region of the housing assembly 30.

[0036] For example, please refer to Figure 2 and Figure 3The atomizer 100 includes an atomizer assembly 10, at least a portion of which is disposed within the housing assembly 30.

[0037] Here, "at least a portion of the atomizer assembly 10 is disposed within the housing assembly 30" can mean that a portion of the structure of the atomizer assembly 10 is disposed within the housing assembly 30, or that the entire structure of the atomizer assembly 10 is disposed within the housing assembly 30.

[0038] For example, please refer to Figure 2 The housing assembly 30 has a liquid storage chamber 100a inside.

[0039] Here, the housing assembly 30 may define the liquid storage chamber 100a, or the housing assembly 30 and the atomizing seat assembly 10 may jointly define the liquid storage chamber 100a.

[0040] In this embodiment of the application, the top of the atomizing seat assembly 10 and the inner sidewall of the housing assembly 30 define a liquid storage chamber 100a for storing the aerosol generation matrix, and the liquid storage chamber 100a is arranged around the gas outlet channel 30a.

[0041] For example, please refer to Figures 2 to 3 The atomizing seat assembly 10 has an atomizing chamber 10a inside, which is connected to the air outlet channel 30a.

[0042] Here, the atomizing chamber 10a may be defined by the atomizing base assembly 10, or the atomizing assembly 20 and the atomizing base assembly 10 may jointly define the atomizing chamber 10a.

[0043] For example, please refer to Figures 2 to 3 The atomizing seat assembly 10 has a liquid inlet channel 10b, one end of which is connected to the liquid storage chamber 100a, and the other end is connected to the liquid in the substrate 21.

[0044] For example, please refer to Figure 3 The atomizing seat assembly 10 has an air intake channel that connects to the outside and the through hole 21c.

[0045] The aerosol generation matrix in the liquid storage chamber 100a enters the atomizing component 20 through the liquid inlet channel 10b for atomization. The aerosol formed after atomization flows through the air outlet channel 30a along with the air flowing in through the air inlet channel and is discharged to the outside for user use through the air outlet of the air outlet channel 30a.

[0046] The atomizing component 20 is used to absorb the aerosol generating matrix and atomize the aerosol generating matrix to form an aerosol. The atomizing component 20 is disposed on the atomizing base assembly 10.

[0047] The substrate 21 is located between the atomizing chamber 10a and the outlet of the liquid inlet channel 10b, and blocks the outlet of the liquid inlet channel 10b.

[0048] In some cases, the atomizing component 20 may also be referred to as the atomizing core.

[0049] For example, please refer to Figure 2 The liquid storage chamber 100a is located on the top side of the atomizing seat assembly 10, and the first surface 21a of the substrate 21 is arranged perpendicular to the top and bottom direction of the atomizer 100.

[0050] The mist outlet of the atomizing chamber 10a is connected to the air outlet channel 30a. The air outlet channel 30a is a channel that extends along the height direction of the atomizer 100. The air outlet channel 30a has a simple structure, is easy to process, and has low airflow resistance.

[0051] For example, the substrate 21 can be made of ceramic material. Ceramic material has the characteristics of good thermal conductivity uniformity. Other materials can also be used for the substrate.

[0052] External air flows through the through-hole 21c and mixes with the atomized product of the atomizing component 20 before flowing to the outlet channel 30a.

[0053] Please see Figures 2 to 4 The substrate 21 includes a first surface 21a and a second surface 21b disposed opposite to each other. The first surface 21a faces the air outlet channel 30a. That is, the first surface 21a is the upper surface of the substrate 21, and the second surface 21b is the upper surface of the substrate 21.

[0054] For example, the second surface 21b can be a plane or a curved surface.

[0055] For example, the substrate 21 can also be spherical, that is, the outer contour of the substrate 21 is a spherical crown. Here, a spherical crown refers to the curved surface remaining after a sphere is cut by a plane. For example, the first surface 21a is a plane and the second surface 21b is a curved surface.

[0056] Here, the number of through holes 21c can be one or more.

[0057] In the embodiments of this application, "multiple" refers to two or more items.

[0058] The two ends of the through hole 21c penetrate the first surface 21a and the second surface 21b, respectively, so that external air can flow through the through hole 21c to the air outlet channel 30a. That is, external air can flow through the air inlet channel to the through hole 21c, and then from the through hole 21c to the atomizing chamber 10a. In this way, external air can flow directly through the through hole 21c inside the substrate 21 to the atomizing chamber 10a above the substrate 21, which can make the mixing between air and aerosol more uniform.

[0059] The atomizer 100 of this application embodiment includes an atomizing component 20 and an air outlet channel 30a. The substrate 21 of the atomizing component 20 includes a first surface 21a and a second surface 21b disposed opposite to each other. The substrate 21 has through holes 21c penetrating the first surface 21a and the second surface 21b. On the one hand, the aerosol generating matrix that permeates from the liquid storage chamber 100a of the atomizer 100 through the substrate 21 can be gathered and guided through the through holes 21c, and the permeated aerosol generating matrix can be buffered, thereby improving the leakage problem and improving the user experience. On the one hand, by setting the first surface 21a towards the air outlet channel 30a and setting at least part of the heating element 22 on the first surface 21a, that is, the atomizing component 20 atomizes towards the air outlet channel 30a, it is beneficial to improve the atomization efficiency. In addition, external air can also flow to the air outlet channel 30a through the through hole 21c. That is, the path of air flowing to the air outlet channel 30a can be planned through the through hole 21c, which is beneficial to the full mixing of air and aerosol, thereby improving the taste and further enhancing the user's experience.

[0060] In related technologies, the atomization surface (heating film) of the atomizing component atomizes downwards and laterally. However, downward atomization suffers from numerous bends in the aerosol output path, resulting in significant losses and low utilization, and is increasingly unable to meet market demands. While lateral atomization can reduce aerosol losses to some extent compared to downward atomization, some aerosol loss may still occur.

[0061] This application sets the atomizing component 20 to atomize upwards, which can directly carry out the aerosol, minimizing aerosol loss and improving aerosol utilization.

[0062] In some embodiments, please refer to Figures 3 to 4 The atomizing component 20 includes a heating element 22, at least a portion of which is disposed on the first surface 21a.

[0063] External air flows through the through-hole 21c and mixes with the atomized product of the heating element 22 on the first surface 21a, and then flows to the air outlet channel 30a.

[0064] The specific structural form of the heating element 22 is not limited here. For example, the heating element 22 is a heating film disposed on the substrate 21.

[0065] The material of the heating film is not limited. For example, the heating film includes, but is not limited to, metals and / or alloys. For example, the heating film is made of aluminum, gold, silver, copper, nickel-chromium alloy, nickel-chromium-iron alloy, iron-chromium-aluminum alloy, nickel, platinum, or titanium, etc.

[0066] "At least some of the heating elements 22 are disposed on the first surface 21a" means that either some of the heating elements 22 are disposed on the first surface 21a, or all of the heating elements 22 are disposed on the first surface 21a.

[0067] At least a portion of the heating element 22 is disposed on the first surface 21a, meaning the first surface 21a is an atomizing surface. This upward atomization method reduces the flow path length of the aerosol formed after atomization, allowing the aerosol to reach the outlet of the outlet channel 30a more quickly for user use. Reducing the flow path length also decreases the possibility of aerosol condensation due to an excessively long path, preventing a decrease in aroma and concentration due to aerosol loss. Simultaneously, it avoids large aerosol droplets clogging the outlet channel 30a or leaking into the power supply component 200, thus preventing damage to the device.

[0068] Furthermore, the interior of the unit is equipped with through holes 21c, allowing air from the intake channel to flow directly to the top of the first surface 21a, carrying the aerosol above the first surface 21a out through the exhaust channel 30a, which further improves the uniformity of air-aerosol mixing.

[0069] For example, the heating element 22 disposed on the first surface 21a is perpendicular to the central axis of the through hole 21c.

[0070] In other embodiments, the heating element 22 may also be disposed on the sidewall of the through hole 21c.

[0071] In some embodiments, please refer to Figures 3 to 4 The through hole 21c includes a first opening 21d formed on the first surface 21a, and at least a portion of the heating element 22 is close to the first opening 21d.

[0072] For example, the heating element 22 near the first opening 21d may be around the periphery of the first opening 21d.

[0073] For example, the through hole 21c also includes a second opening formed on the second surface 21b, that is, air from the air intake channel can flow into the through hole 21c from the second opening on the second surface 21b and into the atomizing chamber 10a from the first opening 21d on the first surface 21a.

[0074] "At least some of the heating elements 22 are close to the first opening 21d" means that some of the heating elements 22 can be set close to the first opening 21d, or all of the heating elements 22 can be set close to the first opening 21d.

[0075] Here, the heating element 22 near the first opening 21d can be a ring of heating elements 22 surrounding the first opening 21d, or the heating element 22 can be provided in a part of the area surrounding the first opening 21d.

[0076] For example, the heating element 22 includes a surrounding portion and an outlet portion. The surrounding portion surrounds the periphery of the first opening 21d. One end of the outlet portion is electrically connected to the surrounding portion, and the other end extends in a direction away from the surrounding portion for electrical connection to the power supply assembly 200.

[0077] In this embodiment, by bringing at least a portion of the heating element 22 close to the first opening 21d, the heating element 22 near the periphery of the first opening 21d can atomize the aerosol generating matrix to generate aerosol. This allows the aerosol to accumulate around the first opening 21d, which in turn facilitates the flow of air from the through hole 21c to the atomization chamber 10a, where it mixes thoroughly with the aerosol. The mixture is then discharged from the mist outlet to the air outlet channel 30a, and finally discharged from the air outlet of the air outlet channel 30a for user use.

[0078] It should be noted that the cross-sectional shape of the through hole 21c is not limited here. For example, it can be circular, elliptical, polygonal, or irregular in shape.

[0079] In some embodiments, please refer to Figure 4 The equivalent diameter of the through hole 21c is greater than or equal to 1 mm.

[0080] Here, the equivalent diameter refers to the diameter of an equivalent circle obtained by calculating the area of ​​a non-circular object to be the same as that of an equivalent circle.

[0081] In this embodiment, by setting the equivalent diameter of the through hole 21c to be greater than or equal to 1 mm, the aerosol matrix generated by the substrate 21 can be effectively aggregated and guided, thereby effectively improving the leakage problem and increasing the air intake efficiency.

[0082] For example, the equivalent diameter of the through hole 21c is greater than or equal to 1.2 mm.

[0083] In some embodiments, the total cross-sectional area of ​​the through-hole is greater than or equal to 0.7 mm. 2 .

[0084] Here, when there is only one through hole, the total flow cross-sectional area of ​​the through hole is the flow cross-sectional area of ​​that through hole. When there are multiple through holes, the total flow cross-sectional area of ​​the through holes is the sum of the flow cross-sectional areas of the multiple through holes.

[0085] In this embodiment, the total flow cross-sectional area of ​​the through-hole is set to be greater than or equal to 0.7 mm. 2 It can effectively aggregate and guide the aerosol matrix generated by the permeation of the substrate 21, thereby effectively improving the leakage problem and increasing the air intake efficiency.

[0086] In some embodiments, please refer to Figure 4 Projected onto a plane perpendicular to the height direction of the atomizer 100, the projection of at least one through hole 21c overlaps with the projection of the air outlet channel 30a.

[0087] This allows air to carry the atomized aerosol through the through-hole 21c to the outlet channel 30a, reducing the length of the aerosol's flow path and enabling the aerosol to reach the outlet of the outlet channel 30a more quickly for user use.

[0088] Here, the projections of all the through holes 21c may overlap with the projection of the air outlet channel 30a, or the projections of some of the through holes 21c may overlap with the projection of the air outlet channel 30a, while the projections of another part of the through holes 21c may not overlap with the projection of the air outlet channel 30a.

[0089] For example, the projection of the through hole 21c is located within the projection range of the air outlet channel 30a.

[0090] For example, the central axis of the through hole 21c coincides with the central axis of the air outlet channel 30a. That is, the through hole 21c and the air outlet channel 30a are coaxially arranged.

[0091] Here, considering assembly tolerances and manufacturing errors of parts, the overlap mentioned here can be either complete overlap or approximate overlap.

[0092] Here, by setting the central axis of the through hole 21c to coincide with the central axis of the air outlet channel 30a, it is further beneficial to improve the uniformity of air and aerosol mixing.

[0093] In some embodiments, please refer to Figures 2 to 4 The atomizer 100 includes an atomizing base assembly 10, and an atomizing component 20 is disposed on the atomizing base assembly 10. The atomizing base assembly 10 is provided with a buffer chamber 10c and an air inlet 13a communicating with the buffer chamber 10c. The buffer chamber 10c is connected to the end of the through hole 21c opposite to the first surface 21a. The air inlet 13a is higher than the bottom wall of the buffer chamber 10c.

[0094] Here, the number of air intake 13a can be one or more.

[0095] By setting up a buffer chamber 10c, the aerosol matrix generated by the liquid storage chamber 100a through the substrate 21 can be collected and guided to the buffer chamber 10c through the through hole 21c, thereby improving the leakage problem.

[0096] The buffer chamber 10c is connected to the end of the through hole 21c that is away from the first surface 21a, so that the aerosol matrix that permeates from the liquid storage chamber 100a of the atomizer 100 through the substrate 21 can be gathered and guided to the buffer chamber 10c through the through hole 21c.

[0097] The air inlet 13a is connected to the buffer chamber 10c. External air enters the buffer chamber 10c through the air inlet 13a and flows from the buffer chamber 10c to the through hole 21c. Here, the flow path of external air entering the buffer chamber 10c through the air inlet 13a and flowing from the buffer chamber 10c to the through hole 21c constitutes the air intake channel.

[0098] The air inlet 13a is higher than the bottom wall of the buffer chamber 10c. In this way, the aerosol matrix that permeates from the liquid storage chamber 100a through the substrate 21 is collected and guided to the buffer chamber 10c through the through hole 21c, reducing the possibility of leakage caused by the air inlet 13a flowing out.

[0099] For example, a portion of the bottom wall of the buffer cavity 10c protrudes to form a protruding post, and an air inlet 13a is formed inside the protruding post.

[0100] Here, the buffering capacity of the aerosol generation matrix in the buffer chamber 10c can be controlled by controlling the height difference between the air inlet 13a and the bottom wall of the buffer chamber 10c. The greater the height difference between the air inlet 13a and the bottom wall of the buffer chamber 10c, the greater the buffering capacity of the aerosol generation matrix in the buffer chamber 10c.

[0101] In some embodiments, please refer to Figures 2 to 3 When projected onto a plane perpendicular to the height direction of the atomizer 100, the projection of at least one through hole 21c does not completely overlap with the projection of the air inlet 13a.

[0102] Here, considering assembly tolerances and manufacturing errors of parts, the parallelism and / or perpendicularity mentioned here can be completely parallel and / or completely perpendicular, or approximately parallel and / or approximately perpendicular.

[0103] In other words, the air inlet 13a is positioned as far away from the through hole 21c as possible.

[0104] Here, the fact that the projection of at least one through hole 21c does not completely overlap with the projection of the air inlet 13a means that the projection of some through holes 21c does not completely overlap with the projection of the air inlet 13a, while the projection of another part of the through holes 21c completely overlaps with the projection of the air inlet 13a, or the projection of all through holes 21c does not completely overlap with the projection of the air inlet 13a.

[0105] Here, incomplete overlap means that it can be completely non-overlapping, that is, there is no overlapping area, or it can be partially overlapping and partially non-overlapping.

[0106] By projecting the projection onto a plane perpendicular to the height direction of the atomizer 100, and setting the projection of at least one through hole 21c to not completely overlap with the projection of the air inlet 13a, it is beneficial to reduce the possibility of the aerosol generation matrix in the through hole 21c flowing into the air inlet 13a. That is, it is possible to make the aerosol generation matrix in the through hole 21c flow into the buffer chamber 10c as much as possible, thereby reducing the possibility of leakage.

[0107] In some embodiments, please refer to Figures 2 to 3 When projected onto a plane perpendicular to the height direction of the atomizer 100, the projection of the substrate 21 and the projection of the air inlet 13a have no overlapping area.

[0108] In other words, the air inlet 13a is positioned as far away from the base 21 as possible.

[0109] By projecting the projection onto a plane perpendicular to the height direction of the atomizer 100, and setting the projection of the substrate 21 and the air inlet 13a to have no overlapping area, it is further beneficial to reduce the possibility of the aerosol generation matrix in the through hole 21c flowing into the air inlet 13a. That is, it is possible to make the aerosol generation matrix in the through hole 21c flow into the buffer chamber 10c as much as possible, thereby further reducing the possibility of leakage.

[0110] In some embodiments, please continue reading Figures 2 to 3 The cavity wall of the buffer cavity 10c is provided with capillary channels 10d, which are used to guide the aerosol generation matrix in the buffer cavity 10c to the matrix 21.

[0111] By providing a capillary channel 10d in the cavity wall of the buffer chamber 10c, the aerosol generation matrix can be guided to the substrate 21 through the capillary channel 10d by the action of capillary force. In other words, the capillary channel 10d in the cavity wall of the buffer chamber 10c can generate a capillary phenomenon on the liquid located in the capillary channel 10d, so as to guide the aerosol generation matrix to the substrate 21 through the capillary channel 10d, realizing the reabsorption and reuse of the aerosol generation matrix, reducing the possibility of leakage and improving the utilization rate of the aerosol generation matrix.

[0112] Capillarity refers to the phenomenon occurring in capillary channels 10d with dimensions small enough to be compared to the radius of curvature of a liquid meniscus. The entire liquid surface becomes curved within the capillary channel 10d, extending the interaction between liquid and solid molecules throughout the liquid, and this surface curvature generates capillary forces. Thus, the buffer chamber 10c can guide the aerosol-generating matrix through the capillary channel 10d to the substrate 21 via these capillary forces. Furthermore, the capillary channel 10d can adsorb and retain a portion of the aerosol-generating matrix, thereby mitigating the risk of leakage from the inlet 13a when the container is placed horizontally or inverted, further reducing the possibility of leakage.

[0113] For example, the sidewall of the buffer cavity 10c is provided with a capillary channel 10d, and / or the bottom wall of the buffer cavity 10c is provided with a capillary channel 10d, and / or the top wall of the buffer cavity 10c is provided with a capillary channel 10d.

[0114] In some embodiments, please refer to Figures 2 to 3 The atomizer assembly 10 includes an atomizer seat and a base 13, with the atomizer assembly 20 at least partially disposed on the atomizer seat. The base 13 is disposed on the side of the atomizer seat opposite to the air outlet channel 30a and defines a buffer chamber 10c between the base and the atomizer seat.

[0115] For example, please refer to Figures 2 to 3 The atomizing base includes an upper atomizing base 11 and a lower atomizing base 12, which are connected and clamp the atomizing component 20 between them. A base 13 is disposed on the side of the lower atomizing base 12 opposite to the upper atomizing base 11, and defines a buffer cavity 10c between the base 13 and the lower atomizing base 12.

[0116] For example, the upper atomizing seat 11, the lower atomizing seat 12, and the base 13 are arranged sequentially along the height direction of the atomizer 100.

[0117] For example, the upper atomizer 11 and the lower atomizer 12 can be an integrated structure or a separate structure.

[0118] For example, the top wall of the atomizing seat 11 and the housing assembly 30 define a liquid storage chamber 100a.

[0119] For example, the upper atomizing seat 11 and the lower atomizing seat 12 define a liquid inlet channel 10b. The liquid inlet of the liquid inlet channel 10b is disposed through the top wall of the upper atomizing seat 11.

[0120] For example, the upper atomizing seat 11 and the lower atomizing seat 12 are connected, and the atomizing component 20 is clamped between the upper atomizing seat 11 and the lower atomizing seat 12, and the atomizing component 20 and the upper atomizing seat 11 define an atomizing cavity 10a located above the first surface 21a.

[0121] Here, the atomizing base 12 and the base 13 can be an integrated structure, which helps to reduce the number of parts and improve assembly efficiency.

[0122] Of course, the atomizing base 12 and the base 13 can also be separate structures, which makes it easier to manufacture the atomizing base 12 and the base 13.

[0123] For example, the base 13 forms the bottom wall of the buffer cavity 10c, that is, the air outlet is higher than the bottom wall of the base 13.

[0124] For example, both the base 13 and the atomizing lower seat 12 are formed with capillary channels 10d.

[0125] For example, a portion of the bottom wall of the base 13 protrudes to form a protruding post, and an air inlet 13a is formed inside the protruding post.

[0126] For example, a sealing ring 40 is provided between the atomizing upper seat 11 and the housing assembly 30, and the sealing ring 40 is used to seal the gap between the atomizing upper seat 11 and the housing assembly 30.

[0127] For example, a sealing ring 40 is provided between the atomizing lower seat 12 and the housing assembly 30, and the sealing ring 40 is used to seal the gap between the atomizing lower seat 12 and the housing assembly 30.

[0128] For example, a sealing ring 40 is provided between the base 13 and the housing assembly 30, and the sealing ring 40 is used to seal the gap between the base 13 and the housing assembly 30.

[0129] For example, the sealing ring 40 is made of an elastic material such as silicone or rubber.

[0130] In some embodiments, please refer to Figures 2 to 4 The atomizer 100 includes an atomizing seat assembly 10, which includes an upper atomizing seat 11 and a lower atomizing seat 12. The upper atomizing seat 11 and the lower atomizing seat 12 are connected and clamp the atomizing component 20 between the upper atomizing seat 11 and the lower atomizing seat 12. The atomizing component 20 includes a sealing member 23. A first surface 21a abuts against the upper atomizing seat 11 through the sealing member 23, and / or a second surface 21b abuts against the lower atomizing seat 12 through the sealing member 23.

[0131] Here, the first surface 21a abuts against the atomizing upper seat 11 through the sealing member 23. The sealing member 23 is used to seal the gap between the first surface 21a and the atomizing upper seat 11, which helps to improve the sealing performance between the first surface 21a and the atomizing upper seat 11, reduces the possibility of the aerosol generation matrix flowing out from the gap between the first surface 21a and the atomizing upper seat 11, and further reduces the possibility of leakage.

[0132] Here, the second surface 21b abuts against the atomizing lower seat 12 through the sealing member 23. The sealing member 23 is used to seal the gap between the second surface 21b and the atomizing lower seat 12, which helps to improve the sealing performance between the second surface 21b and the atomizing lower seat 12, reduces the possibility of the aerosol generation matrix flowing out from the gap between the second surface 21b and the atomizing lower seat 12, and further reduces the possibility of leakage.

[0133] For example, the seal 23 is made of an elastic material such as silicone or rubber.

[0134] In this embodiment, the upper atomizing seat 11 and the lower atomizing seat 12 are connected, and the atomizing component 20 is clamped between the upper atomizing seat 11 and the lower atomizing seat 12. The upper and lower sides of the base 21 are compressed and sealed with the sealing member 23, which further improves the connection reliability and sealing performance between the atomizing component 20 and the atomizing seat assembly 10.

[0135] In some embodiments, please refer to Figures 2 to 4 The atomizing seat assembly 10 is provided with a liquid inlet channel 10b, and an atomizing chamber 10a is defined between the atomizing upper seat 11 and the atomizing assembly 20. The atomizing chamber 10a is connected to the air outlet channel 30a. The surface of the sealing member 23 between the first surface 21a and the atomizing upper seat 11 is provided with a ventilation groove, and the atomizing chamber 10a is connected to the liquid inlet channel 10b through the ventilation groove.

[0136] Here, the sealing element 23 may have a ventilation groove on the surface that contacts the atomizing seat 11, or it may have a ventilation groove on the surface that contacts the substrate 21.

[0137] The aerosol generating matrix in the liquid storage chamber 100a is guided to the atomizing component 20 through the liquid inlet channel 10b to generate aerosol. After the aerosol generating matrix in the liquid storage chamber 100a is consumed, the gas in the atomizing chamber 10a enters the liquid storage chamber 100a through the air exchange groove to balance the pressure in the liquid storage chamber 100a.

[0138] Here, the number of ventilation slots can be one or more.
