[0048] See also Figure 2a 、 Figure 2b 、 Figure 3 and Figure 4 , Figure 2a This is a schematic diagram of the structure of the atomizer assembly provided in this application. Figure 2b for Figure 2a The cross-sectional view of the atomization component along the AA direction, Figure 3 for Figure 2a 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 seat.

[0049] 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 a mounting chamber 110, and the atomizer core 12 is arranged in the mounting chamber 110, that is, the atomizer core 12 is arranged in the receiving chamber 15 together with the atomizer seat 11. An atomizing chamber 111 is formed between the atomizing surface 121 of the atomizer core 12 and the cavity wall of the mounting chamber 110, and the atomizing 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, and the air outlet channel 14 is connected to the atomizing chamber 111. The user inhales the aerosol atomized by the atomizing core 12 through the suction port 17.

[0050] The atomizer seat 11 is usually provided with a ventilation structure to introduce external gas into the liquid storage chamber 13, so as to prevent the liquid storage chamber 13 from being in an excessive negative pressure state and to achieve air pressure balance between the liquid storage chamber 13 and the external atmosphere; so as to facilitate the aerosol generating 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 generating matrix may leak into the microgroove of the ventilation structure, so that the aerosol generating matrix exists in the ventilation structure, and the aerosol generating 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; condensation may be formed when the hot air in the air outlet channel 14 or the atomizer chamber 111 is cooled, and the condensation will leak out after accumulating to a certain volume, thereby causing leakage. In other words, sources of leakage in the atomizer assembly 1 include leakage from the ventilation structure of the liquid storage chamber 13, liquid on the atomizing surface 121 of the atomizer core 12, and condensation in the air outlet channel 14 or the atomizing chamber 111. Leaked liquid may be sucked into the user's mouth, reducing the user experience; leaked liquid may also leak into the power supply assembly 2, causing corrosion and shortening its lifespan.

[0051] To address the problem of liquid leakage, existing solutions typically provide a liquid storage structure on the bottom wall of the atomizing chamber 111 to absorb the leaked liquid. However, because 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 assembly 1 that can efficiently and reliably absorb leaked liquid, avoid suction leakage, and reduce the impact of leakage on the power supply assembly 2.

[0052] The atomizer seat 11 of the present application has at least one liquid collection chamber 16, which is arranged on the side wall of the atomizing chamber 111 and is connected to the atomizing chamber 111. The liquid collection chamber 16 is used to collect liquid leakage from the atomizing surface 121 of the atomizing core 12, the air outlet channel 14, or the condensed liquid in the atomizing chamber 111. A liquid absorption member 161 is provided in the liquid collection chamber 16, which is used to absorb the leakage and fully store the leakage. The dual storage method of the liquid collection chamber 16 and the liquid absorption member 161 fully reduces the risk of the leakage being sucked into the user's mouth (sucked leakage) or the impact of the leakage on the power supply assembly 2. The liquid absorption member 161 is made of a porous loose material that can store and lock liquid, such as absorbent cotton, sponge, porous ceramics, etc. Furthermore, a liquid collection chamber 16 is provided on the side wall of the atomizing chamber 111. This effectively utilizes the width of the atomizing assembly 1 without increasing the volume of the atomizing assembly 1 or the atomizing base 11, thereby efficiently and reliably absorbing leaked liquid. It is understood that the size of the liquid collection chamber 16 is in the millimeter range, providing a large capacity for absorbing leaked liquid.

[0053] Specifically, the atomizer seat 11 includes an atomizer top seat 115 and an atomizer base 116. The atomizer base 116 is located 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 then 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-guiding part and a heating element. The heating element is arranged on one surface of the porous liquid-guiding part. The surface of the porous liquid-guiding part provided with the heating element is the atomizing surface 121; the porous liquid-guiding part uses capillary force to guide the aerosol-generating matrix to the atomizing surface 121, and the heating element arranged on the atomizing surface 121 heats and atomizes to produce aerosol. An 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 atomizer core 12 is opposite to the suction port 17 , that is, the atomizing surface 121 of the atomizer core 12 faces downward.

[0054] In one embodiment, the end surface of the atomizer top seat 115 close to the atomizer base 116 is flat, 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 collection 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 collection chamber 16 (such as Figure 2b As shown in FIG. 1 ); the cross-sectional shape and size of blind hole 163 may be the same as or different from those of blind hole 162, as needed; optionally, the cross-sectional size of blind hole 163 is smaller than that of blind hole 162. By providing blind hole 163 on the surface of atomizer top seat 115 near atomizer base 116, blind hole 163 and blind hole 162 cooperate to form liquid collecting chamber 16, thereby maximizing the capacity of liquid collecting chamber 16 to store leaked liquid, thereby minimizing the risk of leaked liquid flowing into power supply assembly 2.

[0055] Further, 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.

[0056] It can be understood that the shape and size of the absorbent member 161 are coordinated with the shape and size of the liquid collecting chamber 16 so that the absorbent member 161 can fully 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 so as to 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. 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 air 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 significantly increase the liquid storage volume compared to the sheet-like absorbent member 161.

[0057] The top surface of the liquid collecting chamber 16 is no lower than the atomizing surface 121 of the atomizer core 12; and / or the bottom surface of the liquid collecting chamber 16 is no higher than the bottom surface of the atomizing chamber 111. This allows the height of the liquid collecting chamber 16 to be greater than the height of the atomizing chamber 111, thus providing a greater ability to store leaked liquid. The bottom surface of the liquid collecting chamber 16 is no higher than the bottom surface of the atomizing chamber 111, which facilitates the flow of leaked liquid from the atomizing chamber 111 into the liquid collecting chamber 16. The top surface of the liquid collecting chamber 16 is no lower than the atomizing surface 121 of the atomizer core 12. Therefore, whether the end surface of the atomizer top seat 115 near the atomizer base 116 is flat, the liquid collecting chamber 16 is formed by the cooperation of the end surface of the atomizer top seat 115 near the atomizer base 116 and the blind hole 162, or the liquid collecting chamber 16 is formed by the cooperation of the blind hole 163 and the blind hole 162 provided on the surface of the atomizer top seat 115 near the atomizer base 116, 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 no higher than the bottom surface of the atomizing chamber 111 and the top surface of the liquid collecting chamber 16 to no lower than the atomizing surface 121 of the atomizer core 12, the space along the length of the atomizer chamber 111 is fully utilized, the liquid storage capacity of the liquid collecting chamber 16 is maximized, and the space occupied by the liquid collecting chamber 16 along the thickness of the atomizer assembly 1 is reduced, thereby facilitating a thinner and lighter electronic atomizer device. It is 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.

[0058] By providing a first through hole 164 connecting the liquid collecting chamber 16 and the atomizing chamber 111 on the common side wall thereof, the leaked liquid 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. By utilizing the principle that liquid flows from high to low in its natural state, the leaked liquid in the atomizing chamber 111 is quickly diverted into 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 0.5 mm-1.0 mm; preferably, 0.8 mm. It is understood 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 achieve communication between the liquid collecting chamber 16 and the atomizing chamber 111, and the specific design is based on 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.

[0059] See also Figure 3The outer surface of the atomizer seat 11 near the liquid storage chamber 13 is provided with a ventilation groove 112, one end of which is connected to the liquid storage chamber 13 and is used to ventilate the liquid storage chamber 13 to achieve air pressure balance between the liquid storage chamber 13 and the outside atmosphere; the outer surface of the atomizer seat 11 away from the liquid storage chamber 13 is provided with a liquid storage groove 113; the outer surface of the middle part of the atomizer seat 11 is provided with a drainage groove 114, one end of which 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 in the ventilation groove 112 is guided to the liquid storage tank 113 through the drainage groove 114, and the liquid storage tank 113 stores the leaked liquid to prevent the leakage from affecting 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 is absorbed by the liquid absorbent member 161 in the liquid collecting chamber 16, thereby avoiding the 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 needed; 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 and the liquid collecting chamber 16, and most of the leakage in the liquid storage tank 113 comes from the ventilation groove 112 on the atomizer top seat 115, therefore, it is set in the middle to achieve liquid guidance 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 absorption part 161 in the liquid collecting chamber 16, reducing the possibility of leakage caused by liquid saturation at a local position of the liquid absorption part 161.

[0060] 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 the end close to the ventilation groove 112 is smaller than the width and / or depth of the drainage groove 114 at the 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, the width of the drainage groove 114 is 0.2mm-1.5mm, and the depth is 0.2mm-1.5mm. Preferably, the width of the drainage groove 114 at one end close to the liquid storage chamber 13 is 0.4mm, and the depth is 0.3mm.

[0061] 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 form and has a smooth transition with the housing 10 , thereby improving assembly reliability and yield rate.

[0062] By setting the width and / or depth of the end of the drainage groove 114 near the ventilation groove 112 to be smaller than the width and / or depth of the end of the drainage groove 114 near 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 into the liquid storage tank 113, preventing the leakage formed in the ventilation groove 112 from creeping along the gap between the atomizer base 11 and the housing 10 to the air outlet channel 14 and causing suction leakage. In addition, 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 is not easy to flow out of the liquid storage tank 113 in the opposite direction.

[0063] See also Figure 5-Figure 7 , Figure 5 This is a schematic longitudinal section of an embodiment of the drainage groove in the atomizer assembly provided in this application. Figure 6 for Figure 2b The cross-sectional view of the atomizer assembly along the BB direction, Figure 7 This is a schematic longitudinal section of another embodiment of the drainage groove in the atomization assembly provided in the present application.

[0064] 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 at a smaller gradient in the direction from the ventilation groove 112 to the liquid storage tank 113), 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 sectioning 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 As shown). The depth of the drainage groove 114 gradually increases along the direction close to the central axis of the atomizing assembly 1; the cross-sectional shape is a triangle (as shown). 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. 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. The cross-sectional shape and longitudinal cross-sectional shape of the drainage groove 114 are designed as needed.

[0065] In another embodiment, Figure 7 As shown, the drainage groove 114 includes multiple 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. The second sub-drainage groove 1142 is located at the end of the first sub-drainage groove 1141 away from the liquid storage chamber 13. The cross-sectional shape and size of the first sub-drainage groove 1141 remain unchanged, and the cross-sectional shape and size of the second sub-drainage groove 1142 remain unchanged. The cross-sectional shape and size of the second sub-drainage groove 1142 are larger than the cross-sectional shape of the first sub-drainage groove 1141 (the width of the drainage groove 114 increases at a larger gradient along the direction from the ventilation groove 112 to the liquid storage tank 113). One side of the longitudinal cross-sectional shape of the first sub-drainage groove 1141 and one side of the longitudinal cross-sectional shape 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 cutting in a direction parallel to the width of 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.

[0066] See also Figure 8 , Figure 8 yes Figure 3 A schematic diagram of the structure of the atomizer seat from another angle is provided.

[0067] 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. When the liquid storage chamber 13 is under negative pressure, it is used to introduce external air into the liquid storage chamber 13, achieving air pressure balance between the liquid storage chamber 13 and the external atmosphere, and facilitating the smooth delivery of the aerosol-generating matrix to the atomizer 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 shape, as long as it is 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 "U"-shaped or "bow"-shaped structure. 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 .

[0068] Liquid reservoir 113 comprises multiple sub-reservoirs 1131 arranged in parallel and connected end to end, forming a "bow"-shaped structure. A second connecting groove (not shown) is provided at one end of the sub-reservoirs 1131 closest to drainage groove 114, connecting drainage groove 114 to liquid reservoir 113.

[0069] 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.

[0070] See also Figure 9 , Figure 9 for Figure 2b Schematic diagram of the assembly structure of the middle atomizer seat and the first sealing member.

[0071] See also Figure 2b and Figure 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, 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 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.

[0072] See also Figure 2b and Figure 9 The groove 1161 on the atomizer base 116 includes a first side wall and a second side wall that are oppositely arranged, and a third side wall and a fourth side wall that connect the first side wall and the second side wall; the blind hole 162 is provided 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 notches (not shown in the figure). The surface of the atomizer top seat 115 close to the atomizer base 116 is provided with a groove (not shown in the figure), and the groove on the atomizer top seat 115 cooperates with the groove 1161 to form the installation cavity 110; the groove on the atomizer top seat 115 includes a first side wall and a second side wall that are oppositely arranged, and a third side wall and a fourth side wall that connect the first side wall and the second side wall; the blind hole 163 is provided on the first side wall and the second side wall of the groove on the atomizer top seat 115, and the third side wall and the fourth side wall of the groove on the atomizer top seat 115 are both provided with notches (not shown in the figure). The notches on the third and fourth side walls of the groove on the atomizer top seat 115 correspond to the notches on the third and fourth side walls of the groove 1161. The notches on the atomizer top seat 115 and 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 atomizer base 116, allowing external air carrying the aerosol atomized by the atomizer core 12 to flow through both sides of the atomizer core 12 and enter the air outlet channel 14.

[0073] To further prevent leaked liquid from spreading along the gap between the atomizer base 11 and the housing 10 into the airflow channel 19 and then entering the air outlet channel 14, causing leakage during suction, vertical ribs 181 are provided on the sidewalls of the first seal 18 and / or ridges 1152 are provided on the atomizer top base 115. In other words, the vertical ribs 181 provided on the sidewalls of the first seal 18 prevent leaked liquid from entering the airflow channel 19; the ridges 1152 provided on the atomizer top base 115 prevent leaked liquid from entering the airflow channel 19. Furthermore, the ridges 1152 provide structural support for the housing 10, increasing its rigidity, preventing weakening of the structural rigidity of the ultra-thin product, and improving the user experience.

[0074] 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 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.

[0075] The atomizer top seat 115 is provided with ribs 1152 on both sides corresponding to the air flow channel 19, and the ribs 1152 extend along the height direction of the atomizer top seat 115; preferably, the ribs 1152 extend along the edge of the notch on the atomizer top seat 115; more preferably, ribs 1152 are provided on both opposite edges of the notch on the atomizer top seat 115. It can be understood that the extension direction of the ribs 1152 is less than 90 degrees from the central axis direction of the atomizer assembly 1, that is, the extension direction of the ribs 1152 is not parallel to the thickness and width direction of the atomizer assembly 1. Preferably, the extension direction of the ribs 1152 is greater than 0 degrees and less than 90 degrees from the length direction of the atomizer assembly 1; so that when the ribs 1152 contact the shell 10, they can simultaneously support the shell 10 in the length and width directions of the atomizer assembly 1, thereby improving the overall strength and rigidity of the shell 10 or the atomizer assembly 1. The gap between the ribs 1152 and the shell 10 is 0-0.03mm. The height direction of the atomizing top seat 115 is the same as the length direction of the atomizing assembly 1 .

[0076] In a specific embodiment, since part of the air flow channel 19 connecting the air outlet channel 14 and the atomization chamber 111 is 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 4 convex bones 1152 in this embodiment.

[0077] See also Figure 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.

[0078] In the design of the atomizer assembly 1, to facilitate product assembly, a gap of 0.1mm-0.2mm is typically provided between the atomizer seat 11 and the housing 10. However, this presents a potential risk: condensed liquid retained on the outer wall of the atomizer seat 11 can be drawn into the air outlet passage 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 passage 19, the first seal 18 seals the atomizer top seat 115 against the inner surface of the housing 10 while preventing liquid on the outer surface of the atomizer top seat 115 from entering the air flow passage 19 and, in turn, the air outlet passage 14, thereby preventing the risk of suction leakage. By providing ribs 1152 on both sides of the atomizer top seat 115 corresponding to the air flow channel 19, and setting the gap between the ribs 1152 and the shell 10 to 0-0.03 mm (this gap is for easy assembly), the ribs 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 ribs 1152 can support the shell 10, reduce the deformation caused by pressing the shell 10, and help improve the structural rigidity of the ultra-thin product.

[0079] See also Figure 10-12 , Figure 10 for Figure 2b The enlarged schematic diagram of the part in the middle, Figure 11 for Figure 10 Schematic diagram of the cooperation between the first seal and the housing, Figure 12 for Figure 10 Cross-sectional view of the atomization assembly along the CC direction.

[0080] 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 is its cross section, and the cross section is approximately elliptical. Therefore, similar to an ellipse, the longest line segment connecting the two vertices of the atomizer assembly 1 cross section is defined as the major axis, and the line connecting the two closest vertices is defined as the minor axis. Correspondingly, the major and minor axes of the first and third seals 18 and 1162 can be derived.

[0081] At least one first annular protrusion 182 is provided on the sidewall of the first sealing member 18. The first sealing member 18 forms an interference fit with the housing 10 via the first annular protrusion 182. The shape of the first annular protrusion 182 is configured to match the cross-sectional shape of the sidewall of the first sealing member 18. The interference between the long axis vertex of the first annular protrusion 182 and the housing 10 is a first value, and the interference between the short axis vertex of the first annular protrusion 182 and the housing 10 is a second value, with the first value being less than the second value. That is, the interference between the long axis vertex of the first annular protrusion 182 and the housing 10 is less than the interference between the short axis vertex of the first annular protrusion 182 and the housing 10. Furthermore, 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 and second values ​​is selected as needed to prevent leakage of the aerosol-generating substrate in the liquid storage chamber 13.

[0082] In this embodiment, the cross-sectional shape of the housing 10 is elliptical, and the corresponding cross-sectional shape of the first sealing member 18 is also elliptical; see Figure 11 and Figure 12 , region A is the apex of the major axis of the side wall of the first sealing member 18, and region B is the apex of the minor axis of the side wall of the first sealing member 18. It is understood that in order to make the electronic atomization device lighter and thinner, even if the cross-sectional shape of the housing 10 is not elliptical, the cross-section of the housing 10 still has a major axis and a minor axis, and the corresponding cross-sectional shape of the first sealing member 18 also has a major axis and a minor axis. It is only necessary to make the interference between the major axis apex of the first annular protrusion 182 and the housing 10 smaller than the interference between the minor axis apex of the first annular protrusion 182 and the housing 10.

[0083] Because the shell 10 in the ultra-thin electronic atomization device is weaker in thickness than conventional products, the first sealing member 18, designed for sealing, is more susceptible to deformation due to stress, 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. This compensates for the weakened seal caused by deformation of the shell 10, ensures the overall sealing performance of the product, and avoids leakage of the aerosol generating matrix caused by seal failure of the liquid storage chamber 13.

[0084] Furthermore, the interference fit between the first annular protrusion 182 and the housing 10 gradually increases along the circumference of the first annular protrusion 182, from the long axis vertex of the first annular protrusion 182 to the short axis vertex of the first annular protrusion 182. In other words, the force applied to the housing 10 from the long axis vertex corresponding to the first annular protrusion 182 to the short axis vertex corresponding to the first annular protrusion 182 gradually increases along the circumference of the housing 10, so that the force applied to the long axis vertex of the housing 10 corresponding to the first annular protrusion 182 is the smallest, and the force applied to the short axis vertex of the housing 10 corresponding to the first annular protrusion 182 is the largest. This compensates for the weakened seal caused by deformation of the housing 10, ensures the overall sealing performance of the product, and prevents leakage of the aerosol-generating substrate caused by seal 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 from any long axis vertex to one of the short axis vertices, the interference between the first annular protrusion 182 and the housing 10 gradually increases along the circumference of the first annular protrusion 182.

[0085] 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 providing 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.

[0086] See also Figure 9 The vertical rib 181 extends along the height of the sidewall of the first sealing member 18, and the first annular protrusion 182 extends along the circumference of the sidewall of the first sealing member 18. In one embodiment, two first annular protrusions 182 are provided on the sidewall of the first sealing member 18, and the two first annular protrusions 182 are spaced apart. One end of the vertical rib 181 abuts against the first annular protrusion 182 farther from the liquid storage chamber 13, while the other end of the vertical rib 181 extends away from the first annular protrusion 182. Both first annular protrusions 182 and the housing 10 satisfy the aforementioned interference fit.

[0087] A third sealing member 1162 is provided at one end of the atomizer base 116 away from the liquid storage chamber 13. The third sealing member 1162 is arranged along the circumference of the atomizer base 116 and contacts the housing 10 to achieve a seal between the atomizer base 116 and the housing 10. The interference between the long axis vertex of the third sealing member 1162 and the housing 10 is smaller than the interference between the short axis vertex of the third sealing member 1162 and the housing 10. The specific method for setting the interference between the third sealing member 1162 and the housing 10 is the same as the method for setting the interference between the first sealing member 18 and the housing 10, and will not be repeated here.

[0088] 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 weakening of the seal caused by the deformation of the housing 10 is further compensated to ensure the overall sealing performance of the product.

[0089] Continue to see Figure 10 A vent hole 117 is provided at one end of the atomizer seat 11 near 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 connected to the air outlet channel 14, and the vent hole 117 is connected to the atomizing chamber 111, so that the aerosol atomized by the atomizer core 12 can flow out of 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 arranged to fit 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. 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.

[0090] Specifically, the top surface of the liquid guide bone 1171 and the side surface of the liquid guide bone 1171 form an angle α of 70°-80°, forming a pointed tip; preferably, 75°. The top surface of the liquid guide bone 1171 is the end surface of the liquid guide bone 1171 that is closest to the air outlet passage 14; the side surface of the liquid guide bone 1171 is the end surface of the liquid guide bone 1171 that is away from the inner surface of the vent 117, and this end surface is connected to the end surface of the liquid guide bone 1171 that is closest to the air outlet passage 14. The top surface of the liquid guide bone 1171 abuts the end surface of the air outlet passage 14; that is, the end surface of the liquid guide bone 1171 that is closest to the air outlet passage 14 abuts the end surface of the air outlet passage 14.

[0091] In one embodiment, two drainage bones 1171 are symmetrically arranged on the inner surface of the vent 117, and the tips of the two drainage bones 1171 are spaced apart. In one embodiment, the longitudinal section of the drainage bone 1171 is triangular.

[0092] 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 provided 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 liquid accumulation 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 spaced apart, 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.

[0093] Specifically, the vent 117 includes a first region and a second region, with the second region located on the side of the first region away from the outlet channel 14. The shape and size of the vent 171 in the first region remain unchanged, with the end of the outlet channel 14 embedded in the first region. In the second region, the size of the vent 171 gradually decreases away from the outlet channel 14, forming a tapered structure to facilitate the collection of condensate in the outlet channel 14. A liquid guide 1171 is located in the second region. In one embodiment, the longitudinal cross-section of the liquid guide 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 the end surface of the outlet channel 14, and the length H of the side is 0.3-0.7 mm, preferably 0.5 mm, greater than the wall thickness of the outlet channel 14. The shape and size of the liquid guide bone 1171 can be designed as needed, which is conducive to eliminating the accumulation of liquid in the air outlet channel 14 and the mixing of aerosols on both sides.

[0095] See also Figure 10 、 Figure 13 and Figure 14A second seal 122 is provided between the top surface of the atomizer core 12 and the atomizer seat 11; that is, a second seal 122 is provided on the surface of the atomizer core 12 opposite to the atomizing surface 121, and the second seal 122 is provided between the atomizer core 12 and the atomizer top seat 115. An opening 1221 is provided on the second seal 122 to partially expose 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 that are oppositely arranged. 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. A second annular protrusion 1222 is provided on the first surface and / or the second surface of the second seal 122, and the second annular protrusion 1222 surrounds the opening 1221. By providing a second annular protrusion 1222 on the surface of the second sealing member 122, the surface seal is changed to a line seal, thereby reducing the risk of sealing failure caused by uneven pressing.

[0096] The cross-sectional shape of the second annular protrusion 1222 is an arc, preferably, a minor arc. The cross-sectional shape of the second annular protrusion 1222 can be designed as needed, as long as the surface seal can be changed to a line seal.

[0098] 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 this 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 atomizer assembly 1. When in use, one end of the atomizer assembly 1 is inserted into the second accommodating chamber 2012 of the housing 201 and electrically connected to the power supply assembly 2, so that the power supply assembly 2 can supply power to the atomizer assembly 1. In this 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, cylindrical with a square cross-section, etc.

[0099] 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 housed 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 provided 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 provided 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 provided on the inner wall of the first accommodating chamber.

[0100] See also Figure 17 、 Figure 18 and Figure 19 , Figure 17 A partial cross-sectional view of the power supply assembly provided in this application, Figure 18 This is a schematic diagram of the structure of some components in the power supply assembly after assembly. Figure 19 This is a schematic diagram of the structure after the second circuit board, the reinforcement and multiple light-emitting elements are assembled.

[0101] 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.

[0102] 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 of the housing 201, such that the surface of the first circuit board 204 carrying the circuitry is parallel to the length of the housing 201. The first circuit board 204 can be a printed circuit board (PCB). The first circuit board 204 is provided with a control circuit for controlling the operation of the atomizer assembly 1.

[0103] 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. Figure 19The second circuit board 205 includes a main body 2051 and a first connecting portion 2052, which are interconnected. The main body 2051 is used to carry circuits and circuit components, and the first connecting portion 2052 is used to connect to the first circuit board 204. The second circuit board 205 may be a flexible printed circuit (FPC). A FPC is a highly reliable and flexible printed circuit board made of a polyimide or polyester film substrate. FPCs are thin and have good bendability. However, due to their high flexibility, the FPC has low rigidity and poor support for components such as light-emitting diodes (LEDs) mounted thereon. This can easily damage the light-emitting elements 207 during use, resulting in a reduced service life.

[0104] The main body 2051 can be arranged along the length of the housing 201 so that the surface of the main body 2051 carrying the circuit is parallel to the length. The first connecting portion 2052 is provided at the end of the main body 2051 on the side close to the atomizer assembly 1. The first connecting portion 2052 can be bent toward the side of the first circuit board 204 relative to the main body 2051. A portion of the first connecting portion 2052 is electrically connected to the end of the first circuit board 204 facing away from the atomizer assembly 1, thereby electrically connecting the first circuit board 204 to the second circuit board 205. The connection method can be, for example, welding.

[0105] Specifically, such as Figure 19 As shown, the first connecting portion 2052 bends along fold line BB relative to the main body 2051 at a certain angle α toward one side of the first circuit board 204. The bending angle α satisfies 90° < α ≤ 180°, so that the main body 2051 and the projection of the first circuit board 204 onto the side wall 2022 of the bracket 202 partially overlap, thereby saving space along the length of the power supply assembly 2 and improving space utilization along the thickness of the power supply assembly 2. In this embodiment, the bending angle α is 180 degrees, meaning that the first connecting portion 2052 is bent 180 degrees relative to the main body 2051 before connecting to the first circuit board 204. In other embodiments, the first connecting portion 2052 can remain straight relative to the main body 2051 and connected to the first circuit board 204. That is, although the second circuit board 205 is bendable, in this embodiment, the first connecting portion 2052 and the main body 2051 are not bent.

[0106] In this embodiment, the side wall 2022, the main body 2051 and the first circuit board 204 of the bracket 202 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 main body 2051 and the projection of the first circuit board 204 on the side wall 2022 of the bracket 202 can overlap, which can save space for arranging components in the length direction of the first accommodating cavity, and thus can shorten the length direction size of the power supply component 2, which is conducive to the miniaturization of the electronic atomization device.

[0107] like Figure 18 and Figure 19 As shown, multiple light-emitting elements 207 are disposed 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. The light-emitting elements 207 can be a light-emitting lamp, such as an LED lamp. LED lamps have low energy consumption, low cost, and strong stability in use, which can effectively ensure the stability of light emission. The light-emitting elements 207 can serve as indicator lights to indicate the power level of the electronic atomization device, operational feedback, etc.

[0108] The reinforcement member 206 is disposed on the surface of the main body 2051 on the side closest to the first circuit board 204, with the projections of the plurality of light-emitting elements 207 and the reinforcement member 206 on the second circuit board 205 at least partially overlapping. Specifically, the plurality of light-emitting elements 207 are disposed on one side of the second circuit board 205, while the reinforcement member 206 is disposed on the opposite side of the second circuit board 205 from where the plurality of light-emitting elements 207 are located, thereby reinforcing the second circuit board 205 in the area where the plurality of light-emitting elements 207 are located. The reinforcement member 206 may be made of a material having a certain strength and rigidity, such as at least one of a metal sheet, a ceramic sheet, or a hard plastic sheet. It is understood that other materials having a certain degree of rigidity and strength may also meet the requirements for the reinforcement member 206. For cost and other considerations, the reinforcement member 206 is preferably a steel sheet.

[0109] 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, 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.

[0110] 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 lightweight and thinning of the electronic atomization device; the greater the thickness of the reinforcement 206, the higher the strength and rigidity of the reinforcement 206, and the better the reinforcement effect on 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.

[0111] In one embodiment, the reinforcement member 206 may be fixed to the main body portion 2051 . For example, the reinforcement member 206 may be fixed to the main body portion 2051 via an adhesive layer, and the material of the adhesive layer may be double-sided tape.

[0112] Furthermore, in this embodiment, Figure 17 and Figure 18 As shown, the power supply assembly 2 also includes a battery 208, which is electrically connected to the first circuit board 204, thereby providing power to the atomizer assembly 1. The battery 208 is mounted on the bracket 202. The battery 208 is disposed on a side of the first circuit board 204 away from the top wall of the bracket 202, and is disposed on a surface of the main body 2051 away from the side wall 2022 of the bracket 202. A portion of the reinforcement 206 is sandwiched between the battery 208 and the main body 2051, thereby being tightly fitted to the main body 2051. The sandwiching of the reinforcement 206 between the battery 208 and the main body 2051 effectively utilizes the tight fit between the components of the power supply assembly 2, further enhancing the fixation of the reinforcement 206.

[0113] In one embodiment, if Figure 18 and Figure 19 As shown, the first connecting portion 2052 includes a bent portion 2052a and a straight portion 2052b, with the main body 2051, the bent portion 2052a, and the straight portion 2052b being sequentially connected. The bent portion 2052a is connected to the end of the main body 2051 closest to the atomizer assembly 1 and bends at a certain angle α relative to the main body 2051 toward one side of the first circuit board 204. The straight portion 2052b is arranged along the length of the housing 201 and is electrically connected to the first circuit board 204.

[0114] Among them, Figure 17As shown, a portion of the reinforcement member 206 is disposed between the battery 208 and the main body 2051, while another portion of the reinforcement member 206 extends between the first circuit board 204 and the main body 2051. A portion of the reinforcement member 206 is disposed between the battery 208 and the main body 2051, clamped by the battery 208 and the bracket to maintain stability; another portion 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. The end of the reinforcement member 206 proximal to the atomizer assembly 1 is disposed proximal to the bent portion 2052a to limit the bending position of the second circuit board 205. Preferably, the end of the reinforcement member 206 proximal to the atomizer assembly 1 abuts against the recessed portion of the bent portion 2052a.

[0115] See also Figure 17 In this embodiment, multiple light-emitting elements 207, the main body 2051, the reinforcement 206, the straight plate portion 2052b, and the first circuit board 204 are sequentially stacked along the thickness of the housing 201, with their projections onto the bracket 202 partially overlapping. The bent portion 2052a connects the end of the main body 2051 near the atomizer assembly 1 and the end of the straight plate portion 2052b near the atomizer assembly 1. By sequentially stacking the various components along the thickness of the housing 201 and having their projections onto the bracket 202 partially overlap, the space along the thickness of the first accommodating chamber is fully utilized, allowing the multiple components of the power supply assembly 2 to be stacked in the first accommodating chamber in an orderly manner. This helps reduce space waste along the thickness of the first accommodating chamber and, in turn, contributes to a lighter and thinner electronic atomizer device.

[0116] In this embodiment, if Figure 18 As shown, the power supply assembly 2 also includes a third circuit board 209 and a charging interface 210, both of which are mounted on the bracket 202. The second circuit board 205 has a second connecting portion 2053 at one end away from the atomizer assembly 1. The second connecting portion 2053 is electrically connected to the third circuit board 209, thereby electrically connecting the battery 208 to the third circuit board 209. The third circuit board 209 is provided with a charging circuit, through which the battery 208 can be electrically connected to the charging interface 210. The charging interface 210 is used to electrically connect to an external component to enable the external component to charge the battery 208.

[0117] See also Figure 20 , Figure 20 A schematic diagram of the three-dimensional structure of the bracket provided in this application.

[0118] See also Figure 17 and Figure 20In this embodiment, multiple light-emitting elements 207 are spaced apart on the second circuit board 205. A plurality of light-shielding holes 2023 are spaced apart on the sidewalls 2022 of the bracket 202. The multiple light-emitting elements 207 are disposed in the plurality of light-shielding holes 2023. The light-shielding holes 2023 prevent crosstalk and light leakage between the light-emitting elements 207, ensuring uniform brightness across the light-emitting elements 207. Preferably, the number of light-emitting elements 207 and light-shielding holes 2023 is the same, and the multiple light-emitting elements 207 are disposed in different light-shielding holes 2023 to prevent crosstalk and light leakage between adjacent light-emitting elements 207. The light-shielding hole 2023 is arranged in conjunction with the light-emitting element 207 so that the light-emitting element 207 can be completely disposed 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, effectively utilizing the space in the thickness direction of the first accommodating cavity and saving space in the thickness direction of the power supply assembly 2. This embodiment does not require the provision of a light-shielding member in the first accommodating cavity, thereby reducing 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 thickness dimension of the power supply assembly 2, which is conducive to achieving a lightweight and thin electronic atomization device.

[0119] like Figure 17 As shown, the power supply component 2 also includes a light scattering layer 211, which is provided 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 diffuse the light emitted by the light-emitting element 207 evenly, 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-uniform sheet or a light-uniform film. A common way is to set a light-uniform microstructure on the surface of the transparent medium to achieve light uniformity, or to add scattering particles to the transparent medium to achieve light uniformity.

[0120] Specifically, if Figure 17 and Figure 20 As shown, the side of the bracket 202 facing away from the main body 2051 has a mounting groove 2024, and the light scattering layer 211 is disposed in the mounting groove 2024. The thickness of the light scattering layer 211 is the same as the depth of the mounting groove 2024. By disposing 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 overlap 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 thickness dimension of the power supply assembly 2, and facilitating the thinning and lightening of the electronic atomization device.

[0121] like Figure 17As shown, the light-scattering layer 211 is provided with a plurality of light-isolating holes 2111 at intervals. These light-isolating holes 2111 are staggered with the plurality of light-shielding holes 2023, that is, staggered 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 provided at a position corresponding to between two adjacent light-emitting elements 207. Providing the light-isolating holes 2111 on the light-scattering layer 211 further prevents light crosstalk and leakage between adjacent light-emitting elements 207, thereby ensuring uniform brightness across the light-emitting elements 207.
