[0046] See also Figure 2a , Figure 2b , Figure 3 and Figure 4 , Figure 2a A schematic diagram of the structure of the atomizer assembly provided in this application, Figure 2b for Figure 2a A cross-sectional view of the atomizer assembly along the AA direction. Figure 3 for Figure 2a A schematic diagram of the structure of the atomizer seat in the atomizer assembly, Figure 4 for Figure 3 Schematic diagram of the structure of the atomizer base in the atomizer base.

[0047] The atomizer assembly 1 includes a housing 10, an atomizer seat 11 and an atomizer core 12. The housing 10 has a liquid storage chamber 13, an air outlet channel 14 and a receiving chamber 15. The liquid storage chamber 13 is arranged around the air outlet channel 14, and the liquid storage chamber 13 is used to store the aerosol generating matrix. The atomizer seat 11 is arranged in the receiving chamber 15; the atomizer seat 11 has an installation chamber 110, and the atomizer core 12 is arranged in the installation chamber 110, that is, the atomizer core 12 is arranged in the receiving chamber 15 together with the atomizer seat 11. An atomizer chamber 111 is formed between the atomizing surface 121 of the atomizer core 12 and the cavity wall of the installation chamber 110, and the atomizer chamber 111 is connected to the air outlet channel 14. Among them, the atomizing core 12 is used to atomize the aerosol generating matrix in the liquid storage chamber 13 to produce aerosol; one end of the shell 10 has a suction port 17, the suction port 17 is connected to the air outlet channel 14, the air outlet channel 14 is connected to the atomizing chamber 111, and the user inhales the aerosol atomized by the atomizing core 12 through the suction port 17.

[0048] The atomizer seat 11 is usually provided with a ventilation structure to introduce external gas into the liquid storage chamber 13, so as to avoid the liquid storage chamber 13 being in an excessive negative pressure state, and to achieve the air pressure balance between the liquid storage chamber 13 and the external atmosphere; so as to facilitate the aerosol generation matrix in the liquid storage chamber 13 to be transported to the atomizer core 12; and the ventilation structure can usually be a microgroove directly or indirectly connected to the liquid storage chamber 13, and the aerosol generation matrix may leak into the microgroove of the ventilation structure, so that the aerosol generation matrix exists in the ventilation structure, and the aerosol generation matrix in the ventilation structure will leak out after accumulating to a certain volume, resulting in leakage. During the suction process of the atomizer assembly 1, the atomizing surface 121 of the atomizer core 12 may explode, and the exploded liquid will accumulate in the atomizer chamber 111; the hot air in the air outlet channel 14 or the atomizer chamber 111 may form condensed liquid when it encounters cooling, and the condensed liquid will leak out after accumulating to a certain volume, thereby causing leakage. That is to say, the sources of leakage of the atomizer assembly 1 include leakage of the ventilation structure of the liquid storage chamber 13, liquid explosion on the atomizing surface 121 of the atomizer core 12, and condensed liquid in the air outlet channel 14 or the atomizing chamber 111. The leaked liquid may be sucked into the user's mouth, reducing the user's experience; the leaked liquid may leak into the power supply assembly 2, causing corrosion to the power supply assembly 2 and affecting the life of the power supply assembly 2.

[0049] In order to solve the problem caused by liquid leakage, the existing solution usually sets a liquid storage structure on the bottom wall of the atomizing chamber 111 to absorb the leaked liquid; however, since the liquid storage structure is directly or indirectly connected to the atomizing chamber 111 or the air outlet channel 14, the leaked liquid may still be sucked out during the suction process, causing suction leakage. Based on this, the present application provides an atomizing component 1 that can efficiently and reliably absorb the leaked liquid, avoid suction leakage, and reduce the impact of the leakage on the power supply component 2.

[0050] The atomizer seat 11 of the present application has at least one liquid collecting chamber 16, which is arranged on the side wall of the atomizing chamber 111 and is connected to the atomizing chamber 111. The liquid collecting chamber 16 is used to collect the liquid on the atomizing surface 121 of the atomizing core 12, the condensed liquid in the air outlet channel 14 or the atomizing chamber 111 and the leaked liquid. A liquid absorbing member 161 is arranged in the liquid collecting chamber 16, and the liquid absorbing member 161 is used to absorb the leaked liquid and fully store the leaked liquid. The liquid collecting chamber 16 and the liquid absorbing member 161 are used to store the leaked liquid in a dual manner, which fully reduces the risk of the leaked liquid being sucked into the user's mouth (sucking the leaked liquid) or the impact of the leaked liquid on the power supply assembly 2. The liquid absorbing member 161 is made of porous loose materials, which can store and lock liquid, such as: liquid absorbing cotton, sponge, porous ceramics, etc. In addition, a liquid collecting chamber 16 is provided on the side wall of the atomizing chamber 111, which effectively utilizes the space in the width direction of the atomizing assembly 1 without increasing the volume of the atomizing assembly 1 or the atomizing seat 11, thereby realizing efficient and reliable absorption of leaked liquid. It is understandable that the size of the liquid collecting chamber 16 is in the millimeter level, and has a large leakage absorption capacity.

[0051] Specifically, the atomizer seat 11 includes an atomizer top seat 115 and an atomizer base 116. The atomizer base 116 is arranged on the side of the atomizer top seat 115 away from the liquid storage chamber 13. The atomizer top seat 115 is provided with two lower liquid channels 1151, which are symmetrically arranged on both sides of the air outlet channel 14. The lower liquid channels 1151 are connected to the liquid storage chamber 13. The aerosol-generating substrate in the liquid storage chamber 13 enters the atomizer core 12 through the lower liquid channels 1151, and is heated and atomized by the atomizer core 12. Figure 2b , Figure 3 and Figure 4 , the atomizing base 116 has a groove 1161, and the groove 1161 cooperates with the atomizing top seat 115 to form an installation cavity 110, and the atomizing core 12 is arranged in the installation cavity 110. The atomizing core 12 includes a porous liquid guide member and a heating member, and the heating member is arranged on one surface of the porous liquid guide member, and the surface of the porous liquid guide member provided with the heating member is the atomizing surface 121; the porous liquid guide member uses capillary force to guide the aerosol generating matrix to the atomizing surface 121, and the heating member arranged on the atomizing surface 121 heats and atomizes to generate aerosol. The atomizing cavity 111 is formed between the atomizing surface 121 of the atomizing core 12 and the bottom surface of the groove 1161. The side wall of the groove 1161 has a blind hole 162 on the surface facing the atomizing top seat 115, and the blind hole 162 cooperates with the atomizing top seat 115 to form a liquid collecting cavity 16. The atomizing surface 121 of the atomizing core 12 is opposite to the suction port 17 , that is, the atomizing surface 121 of the atomizing core 12 faces downward.

[0052] In one embodiment, the end surface of the atomizer top seat 115 close to the atomizer base 116 is a plane, and the blind hole 162 on the surface of the side wall of the groove 1161 facing the atomizer top seat 115 cooperates with the end surface of the atomizer top seat 115 close to the atomizer base 116 to form the liquid collecting chamber 16. In another embodiment, a blind hole 163 is provided on the surface of the atomizer top seat 115 close to the atomizer base 116, and the blind hole 163 cooperates with the blind hole 162 to form the liquid collecting chamber 16 (such as Figure 2b The cross-sectional shape and size of the blind hole 163 may be the same as or different from the cross-sectional shape and size of the blind hole 162, and may be selected as needed; optionally, the cross-sectional size of the blind hole 163 is smaller than the cross-sectional size of the blind hole 162. By arranging the blind hole 163 on the surface of the atomizing top seat 115 close to the atomizing base 116, the blind hole 163 cooperates with the blind hole 162 to form the liquid collecting chamber 16, so that the capacity of the liquid collecting chamber 16 to store the leaked liquid is as large as possible, thereby preventing the leaked liquid from flowing into the power supply assembly 2 to the greatest extent.

[0053] For further information, see Figure 4 , the two opposite side walls of the groove 1161 are provided with blind holes 162, and the two blind holes 162 cooperate with the atomizing top seat 115 to form two liquid collecting chambers 16; wherein, whether the blind hole 163 is provided on the surface of the atomizing top seat 115 close to the atomizing base 116 is designed as needed. That is to say, in the width direction of the atomizing base 116, the two liquid collecting chambers 16 are arranged on opposite sides of the atomizing chamber 111. Preferably, in the width direction of the atomizing base 116, the two liquid collecting chambers 16 are symmetrically arranged on opposite sides of the atomizing chamber 111. wherein, the width direction of the atomizing base 116 is the same as the width direction of the atomizing assembly 1.

[0054] It can be understood that the shape and size of the absorbent member 161 and the shape and size of the liquid collecting chamber 16 are matched to make the absorbent member 161 fill the liquid collecting chamber 16; the shape and size of the absorbent member 161 and the liquid collecting chamber 16 can be designed as needed, as long as they can absorb the leaked liquid. Preferably, the cross-sections of the liquid collecting chamber 16 and the absorbent member 161 are both regular polygons; more preferably, the cross-sections of the liquid collecting chamber 16 and / or the absorbent member 161 are circular, and the absorbent member 161 with a circular cross-section has a simple product structure, less production waste, and high processing efficiency; when the absorbent member 161 with a circular cross-section is assembled into the liquid collecting chamber 16, there is no need for special alignment and avoidance, the process is simple, and the assembly cost is reduced; and under the same structural space, the absorbent member 161 with a circular cross-section can greatly increase the liquid storage volume compared to the sheet-like absorbent member 161.

[0055] The top surface of the liquid collecting chamber 16 is not lower than the atomizing surface 121 of the atomizing core 12; and / or, the bottom surface of the liquid collecting chamber 16 is not higher than the bottom surface of the atomizing chamber 111, so that the height of the liquid collecting chamber 16 is greater than the height of the atomizing chamber 111, and has a greater ability to store leaked liquid. The bottom surface of the liquid collecting chamber 16 is not higher than the bottom surface of the atomizing chamber 111, which is conducive to the leaked liquid in the atomizing chamber 111 entering the liquid collecting chamber 16. The top surface of the liquid collecting chamber 16 is not lower than the atomizing surface 121 of the atomizing core 12, so that whether the end surface of the atomizing top seat 115 close to the atomizing base 116 is a plane, the end surface of the atomizing top seat 115 close to the atomizing base 116 cooperates with the blind hole 162 to form the liquid collecting chamber 16, or the blind hole 163 and the blind hole 162 set on the surface of the atomizing top seat 115 close to the atomizing base 116 cooperate to form the liquid collecting chamber 16, the height of the liquid collecting chamber 16 is equal to or greater than the height of the atomizing chamber 111, thereby increasing the liquid storage capacity of the liquid collecting chamber 16. By setting the bottom surface of the liquid collecting chamber 16 to be no higher than the bottom surface of the atomizing chamber 111, and the top surface of the liquid collecting chamber 16 is no lower than the atomizing surface 121 of the atomizing core 12, the space in the length direction of the atomizing chamber 111 is fully utilized, the liquid storage capacity of the liquid collecting chamber 16 is increased as much as possible, and the space occupied by the liquid collecting chamber 16 in the thickness direction of the atomizing assembly 1 is reduced, which is conducive to the thinness of the electronic atomizing device. It can be understood that the length direction of the atomizing chamber 111 is the same as the length direction of the atomizing assembly 1. Preferably, the end of the blind hole 162 is not lower than the atomizing surface 121 of the atomizing core 12, and the bottom surface of the blind hole 162 is lower than the bottom surface of the atomizing chamber 111.

[0056] By providing a first through hole 164 connecting the liquid collecting chamber 16 and the atomizing chamber 111 on the common side wall of the liquid collecting chamber 16 and the atomizing chamber 111, the leakage in the atomizing chamber 111 is drained into the liquid collecting chamber 16. The bottom surface or the lowest point of the first through hole 164 is not higher than the bottom surface of the atomizing chamber 111. The principle that the liquid flows from high to low in the natural state is utilized, which is conducive to the rapid diversion of the leakage in the atomizing chamber 111 to the liquid collecting chamber 16. The position of the top surface or the highest point of the first through hole 164 is not limited, as long as the liquid collecting chamber 16 and the atomizing chamber 111 are connected. The size of the first through hole 164 in the direction perpendicular to the length of the atomizing assembly 1 is 0.5mm-1.0mm; preferably, 0.8mm. It is understandable that a groove or notch connecting the liquid collecting chamber 16 and the atomizing chamber 111 can also be provided on the common side wall of the liquid collecting chamber 16 and the atomizing chamber 111 to realize the connection between the liquid collecting chamber 16 and the atomizing chamber 111, and the specific design is made according to the needs. When a notch connecting the liquid collecting chamber 16 and the atomizing chamber 111 is provided on the common side wall of the liquid collecting chamber 16 and the atomizing chamber 111, the bottom surface of the notch is lower than the bottom surface of the atomizing chamber 111, and the size of the notch along the length direction of the atomizing assembly 1 is the same as the height of the blind hole 162, so that when there is a lot of leakage in the atomizing chamber 111, it can be quickly diverted to the liquid collecting chamber 16.

[0057] See also Figure 3, the outer surface of the end of the atomizer seat 11 close to the liquid storage chamber 13 is provided with a ventilation groove 112, one end of the ventilation groove 112 is connected to the liquid storage chamber 13, and is used to ventilate the liquid storage chamber 13 to achieve the air pressure balance between the liquid storage chamber 13 and the outside atmosphere; the outer surface of the end of the atomizer seat 11 away from the liquid storage chamber 13 is provided with a liquid storage chamber 113; the outer surface of the middle part of the atomizer seat 11 is provided with a drainage groove 114, one end of the drainage groove 114 is connected to the other end of the ventilation groove 112, and the other end of the drainage groove 114 is connected to the liquid storage chamber 113. Since there may be aerosol generating matrix leaked from the liquid storage chamber 13 in the ventilation groove 112, the aerosol generating matrix in the ventilation groove 112 will leak out after accumulating to a certain volume, resulting in leakage. The leakage formed by the ventilation groove 112 is guided to the liquid storage chamber 113 through the drainage groove 114, and the liquid storage chamber 113 stores the leakage to avoid the influence of the leakage on the power supply component 2. In one embodiment, a second through hole 165 (such as Figure 2b As shown), the second through hole 165 connects the liquid storage tank 113 with the liquid collecting chamber 16 to guide the leaked liquid in the liquid storage tank 113 to the liquid collecting chamber 16, and then to be absorbed by the liquid absorbent 161 in the liquid collecting chamber 16, thereby avoiding suction of the leaked liquid and preventing the leaked liquid from leaking into the power supply component 2, thereby affecting the performance of the power supply component 2. Among them, the second through hole 165 and the first through hole 164 arranged on the side wall of the blind hole 162 are staggered. The cross-sectional shape of the second through hole 165 can be circular, square or bar-shaped, etc., and can be designed according to needs; the cross-sectional area of ​​the second through hole 165 is 0.2-0.5mm 2 ; Preferably, the cross-sectional shape of the second through hole 165 is a strip, and the cross-sectional size is 0.4mm*0.8mm. The position of the second through hole 165 on the side wall of the liquid collecting chamber 16 is designed as required; preferably, the second through hole 165 is located in the middle of the height direction of the liquid collecting chamber 16, that is, the second through hole 165 is not at the top or bottom position of the liquid collecting chamber 16. It can be understood that since the second through hole 165 connects the liquid storage tank 113 with the liquid collecting chamber 16, and most of the leakage in the liquid storage tank 113 comes from the ventilation groove 112 on the atomizing top seat 115, therefore, it is arranged in the middle to achieve liquid conduction while avoiding structural conflict with the first through hole 164; at the same time, the staggered arrangement of the second through hole 165 and the first through hole 164 can better and faster introduce the leakage into the liquid absorbing member 161 in the liquid collecting chamber 16, reducing the possibility of leakage caused by the saturation of the local position of the liquid absorbing member 161.

[0058] See also Figure 3Specifically, the ventilation groove 112 is arranged on the outer surface of the atomizer top seat 115, and the drainage groove 114 and the liquid storage tank 113 are arranged on the outer surface of the atomizer base 116. Among them, the width and / or depth of the drainage groove 114 at one end close to the ventilation groove 112 is smaller than the width and / or depth of the drainage groove 114 at one end close to the liquid storage tank 113, that is, the width and / or depth of the drainage groove 114 increases in a gradient along the direction from the ventilation groove 112 to the liquid storage tank 113, and the specific setting of the gradient is designed as needed. The width of the drainage groove 114 at the end away from the liquid storage chamber 13 is 0.2mm-1.5mm, and the depth is 0.2mm-1.5mm; the width of the drainage groove 114 at the end close to the liquid storage chamber 13 is 0.2mm-1.5mm, and the depth is 0.2mm-1.5mm. That is to say, the width of the drainage groove 114 is 0.2 mm-1.5 mm, and the depth is 0.2 mm-1.5 mm. Preferably, the width of the drainage groove 114 at one end close to the liquid storage chamber 13 is 0.4 mm, and the depth is 0.3 mm.

[0059] One side of the longitudinal section of the drainage groove 114 is parallel to the length direction of the atomizer seat 11 , so that the drainage groove 114 is easy to shape and has a smooth transition with the housing 10 , thereby improving assembly reliability and yield rate.

[0060] By setting the width and / or depth of the end of the drainage groove 114 close to the ventilation groove 112 to be smaller than the width and / or depth of the end of the drainage groove 114 close to the liquid storage tank 113, when the liquid in the ventilation groove 112 on the outer surface of the atomizer top seat 115 flows to the gap between the atomizer top seat 115 and the atomizer base 116, the drainage groove 114 on the atomizer base 116 drains it to the liquid storage tank 113, avoiding the leakage formed by the ventilation groove 112 from climbing along the gap between the atomizer seat 11 and the housing 10 to the air outlet channel 14 to cause suction leakage. And due to the inclined design of the drainage groove 114, it is easier for the liquid to enter the liquid storage tank 113 for storage and it is not easy to flow out of the liquid storage tank 113 in the opposite direction.

[0061] See also Figure 5-Figure 7 , Figure 5 This is a schematic longitudinal section diagram of an embodiment of a drainage groove in an atomization assembly provided in the present application. Figure 6 for Figure 2b A cross-sectional view of the atomizer assembly along the BB direction. Figure 7 A schematic longitudinal section diagram of another embodiment of the drainage groove in the atomization assembly provided in the present application.

[0062] In one embodiment, the width of the drainage groove 114 gradually increases in the direction away from the liquid storage chamber 13, that is, the width of the drainage groove 114 gradually increases in the direction from the ventilation groove 112 to the liquid storage tank 113 (the width of the drainage groove 114 increases in the direction from the ventilation groove 112 to the liquid storage tank 113 with a small gradient), and one side of the longitudinal section of the drainage groove 114 is parallel to the length direction of the atomizer seat 11. The longitudinal section of the drainage groove 114 is obtained by cutting in a direction parallel to the width of the atomizer assembly 1; the length direction of the atomizer seat 11 is the same as the length direction of the atomizer assembly 1. Preferably, the longitudinal section of the drainage groove 114 is a right triangle or a right trapezoid (such as Figure 5 The depth of the drainage groove 114 gradually increases along the direction close to the central axis of the atomizer assembly 1; the cross-sectional shape is a triangle (as shown in FIG. Figure 5 and Figure 6 As shown), that is, the depth of the drainage groove 114 gradually increases from zero in the width direction along the direction close to the central axis of the atomizer assembly 1. In this embodiment, the overall structure of the drainage groove 114 is a triangular prism shape; by setting the drainage groove 114 to a triangular prism shape, the drainage groove 114 is easy to form, and a smooth transition between the drainage groove 114 and the housing 10 is achieved, thereby improving assembly reliability and yield rate. It can be understood that the cross-sectional shape of the drainage groove 114 can also be an isosceles trapezoid, a semicircle, etc., and the longitudinal cross-sectional shape of the drainage groove 114 can also be any other shape, and the cross-sectional shape and longitudinal cross-sectional shape of the drainage groove 114 are designed as needed.

[0063] In another embodiment, Figure 7 As shown, the drainage groove 114 includes a plurality of sub-drainage grooves of different widths. For example, the drainage groove 114 includes a first sub-drainage groove 1141 and a second sub-drainage groove 1142, and the second sub-drainage groove 1142 is arranged at one end of the first sub-drainage groove 1141 away from the liquid storage chamber 13; the shape and size of the cross section of the first sub-drainage groove 1141 remain unchanged, the shape and size of the cross section of the second sub-drainage groove 1142 remain unchanged, and the cross section of the second sub-drainage groove 1142 is larger than the cross section of the first sub-drainage groove 1141 (the width of the drainage groove 114 increases along the direction from the ventilation groove 112 to the liquid storage tank 113 with a larger gradient). One side of the longitudinal section of the first sub-drainage groove 1141 and one side of the longitudinal section of the second sub-drainage groove 1142 are collinear, and the collinear side is parallel to the length direction of the atomizer seat 11. The longitudinal sections of the first sub-drainage groove 1141 and the second sub-drainage groove 1142 are obtained by sectioning in the width direction parallel to the atomizer assembly 1. In this embodiment, the depths of the first sub-drainage groove 1141 and the second sub-drainage groove 1142 gradually increase from zero in the width direction along the direction close to the central axis of the atomizer assembly 1, so as to achieve a smooth transition between the drainage groove 114 and the housing 10, thereby improving assembly reliability and yield rate.

[0064] See also Figure 8 , Figure 8 yes Figure 3 A schematic diagram of the structure of the atomizer seat from another angle is provided.

[0065] One end of the ventilation groove 112 is connected to the liquid storage chamber 13, and the other end is connected to the drainage groove 114, which is used to introduce external air into the liquid storage chamber 13 when the liquid storage chamber 13 is in a negative pressure state, so as to achieve the air pressure balance between the liquid storage chamber 13 and the external atmosphere, and facilitate the smooth delivery of the aerosol generation matrix to the atomization core 12. The ventilation groove 112 includes a first sub-ventilation groove 1121 and a second sub-ventilation groove 1122. One end of the first sub-ventilation groove 1121 is connected to the liquid storage chamber 13, the other end of the first sub-ventilation groove 1121 is connected to one end of the second sub-ventilation groove 1122, and the other end of the second sub-ventilation groove 1122 is connected to the drainage groove 114. The longitudinal section of the first sub-ventilation groove 1121 can be a strip or other shapes, and it can be connected to the liquid storage chamber 13; the second sub-ventilation groove 1122 includes a plurality of parallel grooves, and the plurality of parallel grooves are connected end to end, that is, the second sub-ventilation groove 1122 is a "return" shape or a "bow" shape structure, and the second sub-ventilation groove 1122 can also be other bending structures. The extension direction of the first sub-ventilation groove 1121 is perpendicular to the extension direction of the grooves in the second sub-ventilation groove 1122. The specific structure of the ventilation groove 112 can be designed as needed, and it can realize ventilation of the liquid storage chamber 13 and connect the liquid storage chamber 13 with the drainage groove 114. The width of the ventilation groove 112 is 0.2mm-1.5mm, and the depth is 0.2mm-1.5mm; preferably, the width of the ventilation groove 112 is 0.3mm and the depth is 0.4mm. It can be understood that a first connecting groove (not shown) is provided at one end of the second sub-ventilation groove 1122 close to the drainage groove 114 , and the first connecting groove enables the ventilation groove 112 to communicate with the drainage groove 114 .

[0066] The liquid storage tank 113 includes a plurality of sub-liquid storage tanks 1131, which are arranged in parallel and connected end to end, that is, the liquid storage tank 113 is a "bow" shaped structure. A second connecting groove (not shown) is arranged at one end of the plurality of sub-liquid storage tanks 1131 that is close to the drainage groove 114, and the second connecting groove connects the drainage groove 114 with the liquid storage tank 113.

[0067] It can be understood that the atomizer top seat 115 and the atomizer base 116 can be integrally formed or detachably connected; when the atomizer top seat 115 and the atomizer base 116 are integrally formed, the corresponding ventilation groove 112, drainage groove 114, and liquid storage tank 113 can be formed through a single processing flow and are interconnected.

[0068] See also Fig. 9 , Fig. 9 for Figure 2b Schematic diagram of the assembly structure of the middle atomizer seat and the first sealing member.

[0069] See also Figure 2a , Figure 2b and Fig. 9 , the atomizer assembly 1 also includes a first seal 18; the first seal 18 includes a top wall and a side wall, the top wall of the first seal 18 is arranged on the top surface of the atomizer top seat 115, and the side wall of the first seal 18 is arranged on the outer side of the atomizer top seat 115. That is to say, the top wall of the first seal 18 is arranged on the top surface of the atomizer seat 11, and the side wall of the first seal 18 is arranged on the outer side of the atomizer seat 11. And the side wall of the first seal 18 covers the ventilation groove 112 arranged on the outer surface of the atomizer top seat 115; that is, the side wall of the first seal 18 cooperates with the ventilation groove 112 to form a ventilation channel (not shown). The gap between the end face of the side wall of the first seal 18 close to the atomizer base 116 and the top surface of the atomizer base 116 is greater than or equal to 0.1mm and less than or equal to 0.3mm; preferably, 0.25mm. It can be understood that the gap between the first sealing member 18 and the top surface of the atomizer base 116 can better ensure the ventilation of the ventilation channel, which can form a ventilation channel surrounding the atomizer base 11 to avoid poor ventilation caused by leakage and blockage.

[0070] See also Figure 2a , Figure 2b and Fig. 9 , the groove 1161 on the atomizing base 116 includes a first side wall and a second side wall arranged oppositely, and a third side wall and a fourth side wall connecting the first side wall and the second side wall; the blind hole 162 is arranged on the first side wall and the second side wall of the groove 1161, and the third side wall and the fourth side wall of the groove 1161 are both provided with a notch (not shown in the figure). The surface of the atomizing top seat 115 close to the atomizing base 116 is provided with a groove (not shown in the figure), and the groove on the atomizing top seat 115 cooperates with the groove 1161 to form the installation cavity 110; the groove on the atomizing top seat 115 includes a first side wall and a second side wall arranged oppositely, and a third side wall and a fourth side wall connecting the first side wall and the second side wall; the blind hole 163 is arranged on the first side wall and the second side wall of the groove on the atomizing top seat 115, and the third side wall and the fourth side wall of the groove on the atomizing top seat 115 are both provided with a notch (not shown in the figure). The notches on the third and fourth side walls of the groove on the atomizer top seat 115 are arranged correspondingly to the notches on the third and fourth side walls of the groove 1161, and the notches on the atomizer top seat 115 and the notches on the atomizer base 116 cooperate with the housing 10 to form an airflow channel 19. That is, the atomizer core 12 is partially exposed to the airflow channel 19 through the notches on the atomizer top seat 115 and the notches on the atomizer base 116, so that the outside air carries the aerosol atomized by the atomizer core 12 and flows through the two sides of the atomizer core 12 into the air outlet channel 14.

[0071] In order to further prevent the leakage from spreading to the air flow channel 19 along the gap between the atomizer seat 11 and the housing 10, and then entering the air outlet channel 14 to cause suction leakage, a vertical convex rib 181 is provided on the side wall of the first seal 18 and / or a convex bone 1152 is provided on the atomizer top seat 115. In other words, the vertical convex rib 181 provided on the side wall of the first seal 18 is used to prevent the leakage from entering the air flow channel 19; the convex bone 1152 provided on the atomizer top seat 115 is used to prevent the leakage from entering the air flow channel 19. At the same time, the convex bone 1152 can achieve structural support for the housing 10, improve the rigidity of the housing 10, avoid weakening of the structural rigidity of the ultra-thin product, and improve the user experience.

[0072] The first seal 18 is provided with vertical ribs 181 on both sides corresponding to the air flow channel 19, and the vertical ribs 181 extend along the height direction of the side wall of the first seal 18. The angle between the extension direction of the vertical rib 181 and the central axis of the atomizer assembly 1 is less than 90 degrees, that is, the extension direction of the vertical rib 181 is not parallel to the thickness and width direction of the atomizer assembly 1; preferably, the extension direction of the vertical rib 181 is parallel to the central axis direction of the atomizer assembly 1, that is, the angle between the two is 0 degrees. And the vertical rib 181 contacts the housing 10; preferably, the length of the vertical rib 181 extending along the height direction of the side wall of the first seal 18 is the same as the height of the side wall of the first seal 18. The height direction of the side wall of the first seal 18 is the same as the length direction of the atomizer assembly 1. In a specific embodiment, since part of the air flow channel 19 connecting the air outlet channel 14 and the atomization chamber 111 is two channels located on both sides of the thickness direction of the atomization component 1, the vertical ribs 181 need to be respectively arranged on both sides of the corresponding two channels, that is, there are a total of 4 vertical ribs 181 in this embodiment.

[0073] The atomizing top seat 115 is provided with convex bones 1152 on both sides corresponding to the air flow channel 19, and the convex bones 1152 extend along the height direction of the atomizing top seat 115; preferably, the convex bones 1152 extend along the sideline of the notch on the atomizing top seat 115; more preferably, convex bones 1152 are provided on the two opposite sidelines of the notch on the atomizing top seat 115. It can be understood that the angle between the extension direction of the convex bone 1152 and the central axis direction of the atomizing assembly 1 is less than 90 degrees, that is, the extension direction of the convex bone 1152 is not parallel to the thickness and width direction of the atomizing assembly 1. Preferably, the extension direction of the convex bone 1152 and the length direction of the atomizing assembly 1 are greater than 0 degrees and less than 90 degrees; so that the convex bone 1152 can simultaneously support the housing 10 in the length and width directions of the atomizing assembly 1 when in contact with the housing 10, thereby improving the overall strength and rigidity of the housing 10 or the atomizing assembly 1. The gap between the convex bone 1152 and the housing 10 is 0-0.03mm. The height direction of the atomizer top seat 115 is the same as the length direction of the atomizer assembly 1 .

[0074] In a specific embodiment, since part of the air flow channel 19 connecting the air outlet channel 14 and the atomization chamber 111 is two channels located on both sides of the thickness direction of the atomization component 1, the convex bones 1152 also need to be arranged on both sides of the corresponding two channels, that is, there are a total of four convex bones 1152 in this embodiment.

[0075] See also Fig. 9 The projections of the convex bone 1152 and the vertical convex rib 181 along the width direction of the atomizer assembly 1 at least partially overlap, thereby achieving a combined seal of the air flow channel 19, preventing the liquid between the atomizer seat 11 and the shell 10 from entering the air flow channel 19 as much as possible, and preventing suction leakage to the greatest extent.

[0076] In the design of the atomizer assembly 1, in order to facilitate product assembly, there is usually a gap of 0.1mm-0.2mm between the atomizer seat 11 and the housing 10, but the hidden danger brought about by this is that the condensed liquid retained on the outer wall of the atomizer seat 11 will be sucked into the air outlet channel 14 during the suction process, causing suction leakage. By providing vertical ribs 181 on both sides of the first seal 18 corresponding to the air flow channel 19, the first seal 18 can achieve the seal between the atomizer top seat 115 and the inner surface of the housing 10, while preventing the liquid on the outer surface of the atomizer top seat 115 from entering the air flow channel 19 and then entering the air outlet channel 14, thereby preventing the risk of suction leakage. By providing convex bones 1152 on both sides of the atomizer top seat 115 corresponding to the air flow channel 19, and setting the gap between the convex bones 1152 and the shell 10 to 0-0.03mm (the gap is for easy assembly), the convex bones 1152 can further effectively prevent the liquid between the atomizer seat 11 and the shell 10 from entering the air flow channel 19 and then entering the air outlet channel 14. At the same time, the convex bones 1152 can support the shell 10, reduce the deformation caused by pressing the shell 10, and help to improve the structural rigidity of the ultra-thin product.

[0077] See also Figure 10-12 , Fig.10 for Figure 2b The enlarged schematic diagram of the part in the figure is as follows: Fig.11 for Fig.10 Schematic diagram of the cooperation between the first seal and the housing, Fig.12 for Fig.10 Cross-sectional view of the atomization assembly along the CC direction.

[0078] Generally speaking, the atomizer assembly 1 is flat as a whole; that is, the cross section of the atomizer assembly 1 perpendicular to its length direction is its cross section, and the cross section is approximately an ellipse. Therefore, similar to an ellipse, the longest line segment connecting two vertices on the cross section of the atomizer assembly 1 is defined as the major axis and the line connecting two vertices with a closer distance is defined as the minor axis, and the major axis and minor axis of the first seal 18 and the third seal 1162 can be obtained accordingly.

[0079] At least one first annular protrusion 182 is provided on the side wall of the first sealing member 18, and the first sealing member 18 is interference-fitted with the housing 10 through the first annular protrusion 182. The shape of the first annular protrusion 182 is arranged in coordination with the cross-sectional shape of the side wall of the first sealing member 18. The interference amount between the long axis vertex of the first annular protrusion 182 and the housing 10 is a first value, and the interference amount between the short axis vertex of the first annular protrusion 182 and the housing 10 is a second value, and the first value is less than the second value. That is, the interference amount between the long axis vertex of the first annular protrusion 182 and the housing 10 is less than the interference amount between the short axis vertex of the first annular protrusion 182 and the housing 10. Further, the difference between the second value and the first value is greater than 0 and less than or equal to 0.05 mm. The difference between the first value and the second value is selected as needed to prevent the leakage of the aerosol generating matrix in the liquid storage chamber 13.

[0080] In this embodiment, the cross-sectional shape of the housing 10 is an ellipse, and the corresponding cross-sectional shape of the first sealing member 18 is also an ellipse; see Fig.11 and Fig.12 , area A is the long axis vertex of the side wall of the first seal 18, and area B is the short axis vertex of the side wall of the first seal 18. It can be understood that in order to make the electronic atomization device thinner and lighter, even if the cross-sectional shape of the shell 10 is not elliptical, the cross-sectional shape of the shell 10 also has a long axis and a short axis, and the corresponding cross-sectional shape of the first seal 18 also has a long axis and a short axis, and the interference between the long axis vertex of the first annular protrusion 182 and the shell 10 is only required to be smaller than the interference between the short axis vertex of the first annular protrusion 182 and the shell 10.

[0081] Since the shell 10 in the ultra-thin electronic atomization device is weaker in thickness direction than conventional products, the first seal 18 designed for sealing inside is more likely to be deformed by force, thereby bringing the risk of weakening the sealing performance of the liquid storage chamber 13. By making the interference between the long axis vertex of the first annular protrusion 182 and the shell 10 smaller than the interference between the short axis vertex of the first annular protrusion 182 and the shell 10, the force on the long axis vertex of the shell 10 corresponding to the first annular protrusion 182 is smaller than the force on the short axis vertex of the shell 10 corresponding to the first annular protrusion 182; that is, the unilateral interference in the width direction is the same as that of conventional products, and the unilateral interference in the thickness direction is larger than the unilateral interference in the width direction, so as to compensate for the weakened sealing caused by the deformation of the shell 10, ensure the overall sealing performance of the product, and avoid the leakage of the aerosol generating matrix caused by the failure of the sealing of the liquid storage chamber 13.

[0082] Furthermore, from the long axis vertex of the first annular protrusion 182 to the short axis vertex of the first annular protrusion 182, the interference between the first annular protrusion 182 and the shell 10 gradually increases along the circumference of the first annular protrusion 182. In other words, the force from the long axis vertex of the shell 10 corresponding to the first annular protrusion 182 to the short axis vertex of the shell 10 corresponding to the first annular protrusion 182 gradually increases along the circumference of the shell 10, so that the force at the long axis vertex of the shell 10 corresponding to the first annular protrusion 182 is the smallest, and the force at the short axis vertex of the shell 10 corresponding to the first annular protrusion 182 is the largest, so as to compensate for the weakened seal caused by the deformation of the shell 10, ensure the overall sealing performance of the product, and avoid the leakage of the aerosol generating matrix caused by the sealing failure of the liquid storage chamber 13. In one embodiment, the first annular protrusion 182 has two opposite long axis vertices and two opposite short axis vertices, and the interference between the first annular protrusion 182 and the housing 10 increases gradually along the circumference of the first annular protrusion 182 from any long axis vertex to one of the short axis vertices.

[0083] In one embodiment, the side wall of the first seal 18 contacts the inner wall surface of the shell 10, and an interference fit with the shell 10 is achieved by setting a first annular protrusion 182 on the side wall of the first seal 18; and the interference fit between the first seal 18 and the shell 10 is adjusted by adjusting the protrusion height of the first annular protrusion 182.

[0084] See also Fig. 9 , the vertical rib 181 extends along the height direction of the side wall of the first seal 18, and the first annular protrusion 182 extends along the circumference of the side wall of the first seal 18. In one embodiment, two first annular protrusions 182 are provided on the side wall of the first seal 18, and the two first annular protrusions 182 are arranged at intervals; one end of the vertical rib 181 abuts against the first annular protrusion 182 of the two first annular protrusions 182 away from the liquid storage chamber 13, and the other end of the vertical rib 181 extends in a direction away from the first annular protrusion 182. The above-mentioned interference fit relationship is satisfied between the two first annular protrusions 182 and the housing 10.

[0085] A third sealing member 1162 is provided at one end of the atomizing base 116 away from the liquid storage chamber 13. The third sealing member 1162 is provided along the circumference of the atomizing base 116 and in contact with the housing 10 to achieve sealing between the atomizing base 116 and the housing 10. The interference between the long axis vertex of the third sealing member 1162 and the housing 10 is less than the interference between the short axis vertex of the third sealing member 1162 and the housing 10. The specific setting method of the interference between the third sealing member 1162 and the housing 10 is the same as the setting method of the interference between the first sealing member 18 and the housing 10, which will not be repeated.

[0086] By making the interference between the long axis apex of the third seal 1162 and the housing 10 smaller than the interference between the short axis apex of the third seal 1162 and the housing 10, the weakened seal caused by the deformation of the housing 10 is further compensated to ensure the overall sealing performance of the product.

[0087] Continue to see Fig.10 , a vent hole 117 is provided at one end of the atomizer seat 11 close to the air outlet channel 14; that is, a vent hole 117 is provided on the atomizer top seat 115, and two lower liquid channels 1151 are located on both sides of the vent hole 117. The vent hole 117 is communicated with the air outlet channel 14, and the vent hole 117 is communicated with the atomization chamber 111, so that the aerosol atomized by the atomizer core 12 flows out from the air outlet channel 14. The end of the air outlet channel 14 is embedded in the vent hole 117; part of the inner surface of the vent hole 117 is fitted with part of the outer surface of the air outlet channel 14, and another part of the inner surface of the vent hole 117 is provided with a liquid guide bone 1171, that is, the inner surface of the part of the vent hole 117 where the air outlet channel 14 is not provided is provided with a liquid guide bone 1171. The side of the liquid guide bone 1171 away from the inner surface of the vent hole 117 forms a tip, and the distance between the tip and the inner surface of the vent hole 117 is a third value H, which is greater than the wall thickness of the outlet channel 14. In a specific embodiment, the third value H is 0.3-0.7 mm greater than the wall thickness of the outlet channel 14; preferably, 0.5 mm.

[0088] Specifically, the top surface of the liquid-drawing bone 1171 and the side surface of the liquid-drawing bone 1171 form an angle α of 70°-80° to form a tip; preferably, 75°. The top surface of the liquid-drawing bone 1171 is the end surface of the liquid-drawing bone 1171 close to the air outlet channel 14; the side surface of the liquid-drawing bone 1171 is the end surface of the liquid-drawing bone 1171 away from the inner surface of the vent 117, and the end surface is connected to the end surface of the liquid-drawing bone 1171 close to the air outlet channel 14. The top surface of the liquid-drawing bone 1171 abuts against the end surface of the air outlet channel 14; that is, the end surface of the liquid-drawing bone 1171 close to the air outlet channel 14 abuts against the end surface of the air outlet channel 14.

[0089] In one embodiment, two drainage bones 1171 are symmetrically arranged on the inner surface of the vent hole 117, and the tips of the two drainage bones 1171 are arranged at an interval. In one embodiment, the longitudinal section of the drainage bone 1171 is a triangle.

[0090] Since condensation forms quickly in the ultra-thin electronic atomization device, it is easy to accumulate into a liquid column in the air outlet channel 14 and cause suction leakage. In this embodiment, the air outlet channel 14 is smooth and has no corners, which is conducive to the sliding of condensate and reduces the accumulation of condensate. At the same time, two liquid guide bones 1171 are symmetrically arranged on the inner surface of the air vent 117, and the third value H of the distance between the tip of the liquid guide bone 1171 and the inner surface of the air vent 117 is greater than the wall thickness of the air outlet channel 14. After the condensate in the air outlet channel 14 contacts the liquid guide bone 1171, it will spread and flow along the surface of the liquid guide bone 1171 under the action of surface tension, and finally flow back to the atomization core 12 to be secondary atomized, eliminating the accumulation of liquid in the air outlet channel 14 and thus preventing the occurrence of suction leakage. The top surface of the liquid guide bone 1171 and the side surface of the liquid guide bone 1171 form an angle to form a tip, and the tips of the two liquid guide bones 1171 are arranged at intervals, that is, there is a gap between the two liquid guide bones 1171, which is conducive to the mixing of aerosols on both sides of the liquid guide bone 1171 and improves the suction taste.

[0091] Specifically, the vent 117 includes a first area and a second area, and the second area is located on the side of the first area away from the outlet channel 14. The shape and size of the vent 171 in the first area remain unchanged, and the end of the outlet channel 14 is embedded in the first area; the size of the vent 171 in the second area gradually decreases along the direction away from the outlet channel 14 to form a shrinkage structure, so as to collect the condensate in the outlet channel 14, and the liquid guide bone 1171 is arranged in the second area. In one embodiment, the longitudinal section of the liquid guide bone 1171 is an isosceles triangle; the base of the isosceles triangle is located on the inner surface of the vent 117; the angle between the two sides of the isosceles triangle is 70°-80°, preferably 75°; one side of the isosceles triangle abuts against the end face of the outlet channel 14, and the length H of the side is 0.3-0.7 mm greater than the wall thickness of the outlet channel 14, preferably 0.5 mm. The shape and size of the liquid guide bone 1171 can be designed as needed, which is conducive to eliminating the accumulated liquid in the air outlet channel 14 and mixing the aerosols on both sides.

An opening 1221 is arranged on the second seal 122 to expose part of the atomizer core 12, and the aerosol generating matrix in the liquid storage chamber 13 enters the atomizer core 12 through the lower liquid channel 1151 and the opening 1221. Specifically, the second seal 122 is annular. The second seal 122 includes a first surface and a second surface arranged opposite to each other, the first surface of the second seal 122 contacts the atomizer core 12, and the second surface of the second seal 122 contacts the atomizer top seat 115.

[0096] The power supply assembly 2 includes a housing 201, a bracket 202 and an electrode connection assembly 203. The housing 201 has a first accommodating chamber (not shown), and the bracket 202 is arranged in the first accommodating chamber. In the present embodiment, the housing 201 also has a second accommodating chamber 2012 connected to the first accommodating chamber, which is used to accommodate part of the atomizing assembly 1. When in use, one end of the atomizing assembly 1 is inserted into the second accommodating chamber 2012 of the housing 201 and is electrically connected to the power supply assembly 2, so that the power supply assembly 2 can supply power to the atomizing assembly 1. In the present embodiment, the housing 201 is a rod-shaped structure with an elliptical cross-section. In other embodiments, the shape of the housing 201 is not limited to this shape, and can also be cylindrical, a column with a square cross-section, etc.

[0097] The bracket 202 is used to install the electrode connection assembly 203 and other components in the power supply assembly 2. The electrode connection assembly 203 and other components in the power supply assembly 2 are accommodated in the first accommodating chamber together with the bracket 202. Among them, the bracket 202 has a top wall 2021 and a side wall 2022 that are connected to each other. The electrode connection assembly 203 is arranged on the top wall 2021, and one end of the electrode connection assembly 203 close to the atomizer assembly 1 is exposed, so that the atomizer assembly 1 can be inserted into the second accommodating chamber 2012 and can be electrically connected to the power supply assembly 2 through the electrode connection assembly 203. The side wall 2022 is arranged on the side of the top wall 2021 away from the atomizer assembly 1, and extends along the length direction of the shell 201. In this embodiment, the side wall 2022 is arranged on the inner wall of the first accommodating chamber.

[0098] See also Fig.17 , Fig.18 and Fig.19 , Fig.17 A partial cross-sectional view of a power supply assembly provided in this application, Fig.18 This is a schematic diagram of the structure of some components in the power supply assembly after assembly. Fig.19 It is a schematic diagram of the structure after the second circuit board, the reinforcement and the multiple light-emitting elements are assembled.

[0099] The power supply assembly 2 further includes a first circuit board 204, a second circuit board 205, a reinforcement 206 and a plurality of light emitting elements 207. The first circuit board 204, the second circuit board 205, the reinforcement 206 and the plurality of light emitting elements 207 are all disposed on the same side of the side wall 2022 of the bracket 202.

[0100] The first circuit board 204 is electrically connected to the electrode connection assembly 203. The first circuit board 204 can be arranged along the length direction of the housing 201 so that the surface of the first circuit board 204 carrying the circuit is parallel to the length direction of the housing 201. The first circuit board 204 can be a printed circuit board (PCB), and a control circuit is provided on the first circuit board 204 for controlling the operation of the atomization assembly 1.

[0101] The second circuit board 205 is stacked with the first circuit board 204, and the second circuit board 205 is disposed between the first circuit board 204 and the side wall 2022 of the bracket 202. Fig.19The second circuit board 205 includes a main body 2051 and a first connection part 2052 connected to each other. The main body 2051 is used to carry circuits and circuit elements, and the first connection part 2052 is used to connect to the first circuit board 204. The second circuit board 205 can be a flexible printed circuit (FPC). The flexible printed circuit is a printed circuit board with high reliability and excellent flexibility supported by polyimide or polyester film as a substrate. The flexible printed circuit is thin and has good bendability. However, it is precisely because the FPC has good flexibility and low rigidity that it has poor support for components such as light-emitting diodes (LEDs) arranged thereon. During use, the light-emitting element 207 may be easily damaged and have a low service life.

[0102] The main body 2051 can be arranged along the length direction of the housing 201 so that the surface of the main body 2051 carrying the circuit is parallel to the length direction. The first connecting portion 2052 is provided at the end of the main body 2051 close to the atomizer assembly 1, and the first connecting portion 2052 can be bent toward one side of the first circuit board 204 relative to the main body 2051, and part of the first connecting portion 2052 is electrically connected to the end of the first circuit board 204 away from the atomizer assembly 1, so that the first circuit board 204 is electrically connected to the second circuit board 205, and the connection method can be, for example, welding.

[0103] Specifically, Fig.19 As shown, the first connection portion 2052 is bent along the folding line BB at a certain angle α relative to the main body 2051 toward one side of the first circuit board 204, and the bending angle α satisfies 90°<α≤180°, so that the main body 2051 and the projection of the first circuit board 204 on the side wall 2022 of the bracket 202 partially overlap, thereby saving space in the length direction of the power supply assembly 2 and improving the space utilization rate in the thickness direction of the power supply assembly 2. In this embodiment, the bending angle α is 180 degrees, that is, the first connection portion 2052 is connected to the first circuit board 204 after being bent 180 degrees relative to the main body 2051. In some other embodiments, the first connection portion 2052 can also remain in a straight connection state relative to the main body 2051 and be connected to the first circuit board 204; that is, although the second circuit board 205 is bendable, in this embodiment, the first connection portion 2052 and the main body 2051 are not bent.

[0104] In this embodiment, the side wall 2022 of the bracket 202, the main body 2051 and the first circuit board 204 are all arranged along the length direction of the shell 201. Therefore, by bending the first connecting portion 2052 toward one side of the first circuit board 204 at a certain angle relative to the main body 2051, the projection of the main body 2051 and the first circuit board 204 on the side wall 2022 of the bracket 202 can be overlapped, which can save space for arranging components in the length direction of the first accommodating cavity, and then shorten the length direction of the power supply component 2, which is conducive to the miniaturization of the electronic atomization device.

[0105] like Fig.18 and Fig.19 As shown, a plurality of light-emitting elements 207 are arranged on the surface of the main body 2051 away from the first circuit board 204, and are electrically connected to the first circuit board 204, wherein the light-emitting element 207 can be a light-emitting lamp body, for example, an LED lamp, which has low energy consumption, low cost, and strong stability in use, and can effectively ensure the stability of light emission. The light-emitting element 207 can be used as an indicator light to indicate the power of the electronic atomization device, operation feedback, etc.

[0106] The reinforcement 206 is arranged on the surface of the main body 2051 close to the first circuit board 204, and the projections of the plurality of light-emitting elements 207 and the reinforcement 206 on the second circuit board 205 at least partially overlap; that is, the plurality of light-emitting elements 207 are arranged on one side of the second circuit board 205, and the reinforcement 206 is arranged on the other side of the second circuit board 205 opposite to the location of the plurality of light-emitting elements 207, and is used to reinforce the second circuit board 205 where the plurality of light-emitting elements 207 are located. The reinforcement 206 can be a material with a certain strength and rigidity, for example, it can be at least one of a metal sheet, a ceramic sheet or a hard plastic sheet. It can be understood that other materials with a certain rigidity and strength also meet the requirements of the reinforcement 206. Considering factors such as cost, the reinforcement 206 is preferably a steel sheet.

[0107] By arranging a reinforcement member 206 on the other side of the second circuit board 205 where the multiple light-emitting elements 207 are located, the second circuit board 205 where the multiple light-emitting elements 207 are located can be reinforced, thereby effectively improving the strength and rigidity of the second circuit board 205 where the multiple light-emitting elements 207 are located, thereby preventing damage to the light-emitting elements 207 and increasing the service life of the light-emitting elements 207.

[0108] In one embodiment, the thickness of the reinforcement 206 is 0.05mm-0.5mm. The smaller the thickness of the reinforcement 206, the smaller the space occupied in the thickness direction of the first accommodating cavity, which is conducive to the thinness of the electronic atomization device; the larger the thickness of the reinforcement 206, the higher the strength and rigidity of the reinforcement 206, and the better the reinforcement effect of the second circuit board 205 where the multiple light-emitting elements 207 are located. Therefore, controlling the thickness of the reinforcement 206 within a certain range can make the reinforcement 206 occupy a smaller space in the thickness direction of the first accommodating cavity, while the strength and rigidity of the reinforcement 206 are also moderate. When realizing the ultra-thinness of the electronic atomization device, the thickness of the reinforcement 206 can be 0.15mm.

[0109] In one embodiment, the reinforcement member 206 may be fixed to the main body 2051 . For example, the reinforcement member 206 may be fixed to the main body 2051 via an adhesive layer, and the material of the adhesive layer may be a double-sided adhesive.

[0110] Furthermore, in this embodiment, if Fig.17 and Fig.18 As shown, the power supply assembly 2 also includes a battery 208, and the battery 208 is electrically connected to the first circuit board 204, so that the battery 208 can provide power to the atomizer assembly 1. The battery 208 is installed on the bracket 202, and the battery 208 is arranged on the side of the first circuit board 204 away from the top wall of the bracket 202, and is arranged on the surface of the side wall 2022 of the main body 2051 away from the bracket 202, and part of the reinforcement 206 is sandwiched between the battery 208 and the main body 2051, so as to be arranged on the main body 2051 through a tight fit. The reinforcement 206 is sandwiched between the battery 208 and the main body 2051, which effectively utilizes the tight fit between the components in the power supply assembly 2, and can further enhance the fixation of the reinforcement 206.

[0111] In one embodiment, if Fig.18 and Fig.19 As shown, the first connecting portion 2052 has a bending portion 2052a and a straight plate portion 2052b, and the main body 2051, the bending portion 2052a and the straight plate portion 2052b are connected in sequence. The bending portion 2052a is connected to one end of the main body 2051 close to the atomizer assembly 1, and is bent at a certain angle α relative to the main body 2051 toward one side of the first circuit board 204. The straight plate portion 2052b is arranged along the length direction of the housing 201 and is electrically connected to the first circuit board 204.

[0112] Among them, Fig.17As shown, a part of the reinforcement member 206 is arranged between the battery 208 and the main body 2051, and another part of the reinforcement member 206 extends between the first circuit board 204 and the main body 2051. A part of the reinforcement member 206 is arranged between the battery 208 and the main body 2051, and is clamped by the battery 208 and the bracket to maintain stability; another part of the reinforcement member 206 extends between the first circuit board 204 and the main body 2051, and can be suspended to support the main body 2051. One end of the reinforcement member 206 close to the atomizer assembly 1 is arranged close to the bending portion 2052a to limit the bending position of the second circuit board 205. Preferably, one end of the reinforcement member 206 close to the atomizer assembly 1 abuts against the inner concave part of the bending portion 2052a.

[0113] See also Fig.17 In this embodiment, a plurality of light emitting elements 207, a main body 2051, a reinforcing member 206, a straight plate portion 2052b and a first circuit board 204 are stacked in sequence along the thickness direction of the housing 201, and the projections on the bracket 202 overlap, and the bent portion 2052a connects the end of the main body 2051 close to the atomizer assembly 1 and the end of the straight plate portion 2052b close to the atomizer assembly 1. By stacking the various elements in sequence along the thickness direction of the housing 201, and making the projections of the various elements on the bracket 202 overlap, the space in the thickness direction of the first accommodating cavity can be fully utilized, and the multiple elements in the power supply assembly 2 can be stacked in the first accommodating cavity in an orderly manner, which is conducive to reducing the waste of space in the thickness direction of the first accommodating cavity, and further conducive to the thinness of the electronic atomizer device.

[0114] In this embodiment, if Fig.18 As shown, the power supply assembly 2 also includes a third circuit board 209 and a charging interface 210, and the third circuit board 209 and the charging interface 210 are both mounted on the bracket 202. Among them, the second circuit board 205 has a second connecting portion 2053 at one end away from the atomizer assembly 1, and the second connecting portion 2053 is electrically connected to the third circuit board 209, so that the battery 208 is electrically connected to the third circuit board 209. A charging circuit is provided on the third circuit board 209, and the battery 208 can be electrically connected to the charging interface 210 through the charging circuit. The charging interface 210 is used to be electrically connected to an external component to enable the external component to charge the battery 208.

[0115] See also Fig. 20 , Fig. 20 A schematic diagram of a three-dimensional structure of the bracket provided in this application.

[0116] See also Fig.17 and Fig. 20In this embodiment, a plurality of light emitting elements 207 are arranged at intervals on the second circuit board 205, a plurality of light shielding holes 2023 are arranged at intervals on the side wall 2022 of the bracket 202, and the plurality of light emitting elements 207 are arranged in the plurality of light shielding holes 2023. The light shielding holes 2023 can prevent cross-light and light leakage between the light emitting elements 207, thereby ensuring uniform brightness of each light emitting element 207. Preferably, the number of the light emitting elements 207 and the light shielding holes 2023 are the same, and the plurality of light emitting elements 207 are respectively arranged in different light shielding holes 2023, so as to prevent cross-light and light leakage between adjacent light emitting elements 207. The light shielding hole 2023 is arranged in cooperation with the light emitting element 207 so that the light emitting element 207 can be completely arranged in the light shielding hole 2023, that is, each light emitting element 207 is embedded in the bracket 202, so that the light emitting element 207 and the side wall 2022 of the bracket 202 are overlapped in the thickness direction of the power supply assembly 2, which effectively utilizes the space in the thickness direction of the first accommodating cavity and can save the space in the thickness direction of the power supply assembly 2. In this embodiment, there is no need to set a light shielding member in the first accommodating cavity, which reduces the number of components in the power supply assembly 2 and the corresponding assembly process, thereby reducing the manufacturing cost of the power supply assembly 2; it can also reduce the size of the power supply assembly 2 in the thickness direction, which is conducive to realizing the lightness and thinness of the electronic atomization device.

[0117] like Fig.17 As shown, the power supply assembly 2 also includes a light scattering layer 211, which is arranged on the side of the bracket 202 away from the main body 2051, and the light scattering layer 211 covers a plurality of light shielding holes 2023. The light scattering layer 211 is used to guide light to the light-emitting element 207 in the light shielding hole 2023, and to evenly diffuse the light emitted by the light-emitting element 207, so that the emitted light is uniform, and prevents the low light from being bright and the high light from being dark. The light scattering layer 211 can be a light scattering sheet or a light scattering film. It should be noted that the light scattering sheet or the light scattering film can also be called a light homogenizing sheet or a light homogenizing film. A common method is to set a light homogenizing microstructure on the surface of a light-transmitting medium to achieve light homogenization, and scattering particles can also be added to the light-transmitting medium to achieve light homogenization.

[0118] Specifically, Fig.17 and Fig. 20 As shown, the side of the bracket 202 away from the main body 2051 has a mounting groove 2024, and the light scattering layer 211 is arranged in the mounting groove 2024, and the thickness of the light scattering layer 211 is the same as the depth of the mounting groove 2024. By arranging the light scattering layer 211 in the mounting groove 2024 of the bracket 202, the light scattering layer 211 and the side wall 2022 of the bracket 202 can be overlapped in the thickness direction of the first accommodating cavity, effectively utilizing the space in the thickness direction of the first accommodating cavity, thereby reducing the size of the power supply component 2 in the thickness direction, which is conducive to realizing the lightness and thinness of the electronic atomization device.

[0119] like Fig.17As shown, a plurality of light-isolating holes 2111 are arranged at intervals on the light-scattering layer 211, and the plurality of light-isolating holes 2111 are arranged in a staggered manner with the plurality of light-shielding holes 2023, that is, the plurality of light-isolating holes 2111 are arranged in a staggered manner with the plurality of light-emitting elements 207. Specifically, the number of light-isolating holes 2111 is one less than the number of light-emitting elements 207, and each light-isolating hole 2111 is arranged at a position corresponding to between two adjacent light-emitting elements 207. The light-isolating holes 2111 are arranged on the light-scattering layer 211, which can further prevent light crosstalk and light leakage between adjacent light-emitting elements 207, and further make the brightness of the light-emitting elements 207 uniform.
