[0043] The following provides a detailed description of this application in conjunction with the drawings and embodiments.

[0044] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of the electronic atomization device provided by this application.

[0045] The electronic atomization device can be used for atomizing liquid matrices. The electronic atomization device includes an interconnected atomization component 1 and a power supply component 2. The atomization component 1 is used to store the liquid aerosol-generating matrix and atomize the aerosol-generating matrix to form an aerosol for the user to inhale. The liquid aerosol-generating matrix can be a liquid matrix such as a liquid medicine or a liquid of plant leaves. The atomization component 1 can be specifically used in different fields, such as medical treatment, electronic aerosolization, etc. The power supply component 2 includes components such as a battery, an airflow sensor, a PCB, and a controller. The battery is used to supply power to the atomization component 1 so that the atomization component 1 can atomize the aerosol-generating matrix to form an aerosol. The airflow sensor is used to detect the airflow change in the electronic atomization device, and the controller controls whether the atomization component 1 works according to the airflow change detected by the airflow sensor and a preset program. The atomization component 1 and the power supply component 2 can be integrally arranged or detachably connected, and are designed according to specific needs.

[0046] Please refer to Figure 2a , Figure 2b , Figure 3 and Figure 4 , Figure 2a which are the schematic structural diagrams of the atomization component provided by this application. Figure 2b is Figure 2a the sectional view of the atomization component along the A-A direction. Figure 3 is Figure 2a the schematic structural diagram of the atomization seat in the atomization component. Figure 4 is Figure 3 the schematic structural diagram of the atomization base in the atomization seat.

[0047] The atomization component 1 includes a housing 10, an atomization seat 11, and an atomization core 12. The housing 10 has a liquid storage cavity 13, an air outlet channel 14, and a receiving cavity 15. The liquid storage cavity 13 is arranged around the air outlet channel 14, and the liquid storage cavity 13 is used to store the aerosol-generating matrix. The atomization seat 11 is arranged in the receiving cavity 15. The atomization seat 11 has an installation cavity 110, and the atomization core 12 is arranged in the installation cavity 110. That is to say, the atomization core 12 and the atomization seat 11 are arranged in the receiving cavity 15 together. An atomization cavity 111 is formed between the atomization surface 121 of the atomization core 12 and the cavity wall of the installation cavity 110, and the atomization cavity 111 is communicated with the air outlet channel 14. Among them, the atomization core 12 is used to atomize the aerosol-generating matrix in the liquid storage cavity 13 to generate an aerosol. One end of the housing 10 has a suction port 17, the suction port 17 is communicated with the air outlet channel 14, the air outlet channel 14 is communicated with the atomization cavity 111, and the user sucks the aerosol atomized by the atomization core 12 through the suction port 17.

[0048] The atomization base 11 is usually provided with a ventilation structure to introduce external gas into the liquid storage cavity 13, avoid the liquid storage cavity 13 being in an excessive negative pressure state, and achieve the air pressure balance between the liquid storage cavity 13 and the external atmosphere; so as to facilitate the delivery of the aerosol generation matrix in the liquid storage cavity 13 to the atomization core 12; and the ventilation structure can usually be a microgroove directly or indirectly communicated with the liquid storage cavity 13. The aerosol generation matrix may leak into the microgroove of the ventilation structure, resulting in the presence of the aerosol generation matrix in the ventilation structure. After the aerosol generation matrix in the ventilation structure accumulates to a certain volume, it will leak out, resulting in a liquid leakage phenomenon. During the suction process of the atomization assembly 1, liquid explosion may occur on the atomization surface 121 of the atomization core 12, and the exploded liquid will accumulate in the atomization cavity 111; the hot air in the air outlet channel 14 or the atomization cavity 111 may form condensate when it meets cold, and when the condensate accumulates to a certain volume, it will leak out, thus causing a liquid leakage situation. That is to say, the liquid leakage sources of the atomization assembly 1 include the liquid leakage of the ventilation structure of the liquid storage cavity 13, the liquid explosion of the atomization surface 121 of the atomization core 12, and the condensate in the air outlet channel 14 or the atomization cavity 111. The liquid leakage may be sucked into the user's mouth, reducing the user's experience; the liquid leakage may leak into the power supply assembly 2, corroding the power supply assembly 2 and affecting the service life of the power supply assembly 2.

[0049] In order to solve the problems brought by liquid leakage, the existing solutions usually set a liquid storage structure on the bottom wall of the atomization cavity 111 for absorbing liquid leakage; however, since the liquid storage structure is directly or indirectly communicated with the atomization cavity 111 or the air outlet channel 14, liquid leakage may still be sucked out during the suction process, causing suction liquid leakage. Based on this, the present application provides an atomization assembly 1 that can efficiently and reliably absorb liquid leakage, avoid suction liquid leakage, and reduce the impact of liquid leakage on the power supply assembly 2.

[0050] The atomization base 11 of the present application has at least one liquid collection cavity 16. The liquid collection cavity 16 is arranged on the side wall of the atomization cavity 111 and communicated with the atomization cavity 111. The liquid collection cavity 16 is used to collect the liquid leakage formed by the liquid explosion of the atomization surface 121 of the atomization core 12, and the condensate in the air outlet channel 14 or the atomization cavity 111. An absorbent member 161 is arranged in the liquid collection cavity 16. The absorbent member 161 is used to absorb the liquid leakage and store the liquid leakage sufficiently. By using the double storage method of the liquid collection cavity 16 and the absorbent member 161, the risk of the liquid leakage being sucked into the user's mouth (suction liquid leakage) or the impact of the liquid leakage on the power supply assembly 2 is reduced sufficiently. The absorbent member 161 is made of porous and loose materials and can store and lock the liquid, such as absorbent cotton, sponge, porous ceramics, etc. And by arranging the liquid collection cavity 16 on the side wall of the atomization cavity 111, the space in the width direction of the atomization assembly 1 is effectively utilized without increasing the volume of the atomization assembly 1 or the atomization base 11, realizing efficient and reliable absorption of liquid leakage. It can be understood that the size of the liquid collection cavity 16 is in millimeters and has a large liquid leakage absorption capacity.

[0051] Specifically, the atomization base 11 includes an atomization top base 115 and an atomization bottom base 116. The atomization bottom base 116 is disposed on a side of the atomization top base 115 away from the liquid storage chamber 13. Two liquid-down channels 1151 are provided on the atomization top base 115. The two liquid-down channels 1151 are symmetrically arranged on both sides of the air outlet channel 14, and the liquid-down channels 1151 communicate with the liquid storage chamber 13. The aerosol-forming substrate in the liquid storage chamber 13 enters the atomization core 12 through the liquid-down channels 1151, and is thus heated and atomized by the atomization core 12. Refer to Figure 2b , Figure 3 and Figure 4 , the atomization bottom base 116 has a groove 1161. The groove 1161 and the atomization top base 115 cooperate to form an installation cavity 110, and the atomization core 12 is disposed in the installation cavity 110. The atomization core 12 includes a porous liquid guide and a heating element. The heating element is disposed on one surface of the porous liquid guide. The surface of the porous liquid guide provided with the heating element is the atomization surface 121. The porous liquid guide uses capillary action to guide the aerosol-forming substrate to the atomization surface 121, and is heated and atomized by the heating element disposed on the atomization surface 121 to generate aerosol. An atomization cavity 111 is formed between the atomization surface 121 of the atomization core 12 and the bottom surface of the groove 1161. The surface of the side wall of the groove 1161 facing the atomization top base 115 has a blind hole 162. The blind hole 162 and the atomization top base 115 cooperate to form a liquid collection cavity 16. Among them, the atomization surface 121 of the atomization core 12 faces away from the suction port 17, that is, the atomization surface 121 of the atomization core 12 faces downward.

[0052] In one embodiment, the end surface of the atomization top base 115 close to the atomization bottom base 116 is a plane. The blind hole 162 on the surface of the side wall of the groove 1161 facing the atomization top base 115 and the end surface of the atomization top base 115 close to the atomization bottom base 116 cooperate to form a liquid collection cavity 16. In another embodiment, a blind hole 163 is provided on the surface of the atomization top base 115 close to the atomization bottom base 116. The blind hole 163 and the blind hole 162 cooperate to form a liquid collection cavity 16 (as shown in Figure 2b ); the cross-sectional shape and size of the blind hole 163 can be the same as or different from those of the blind hole 162, and can be selected according to needs. Optionally, the cross-sectional size of the blind hole 163 is smaller than that of the blind hole 162. By providing the blind hole 163 on the surface of the atomization top base 115 close to the atomization bottom base 116, the blind hole 163 and the blind hole 162 cooperate to form a liquid collection cavity 16, so that the liquid collection cavity 16 has the largest possible liquid leakage storage capacity, and further maximally avoids the leakage liquid from flowing into the power supply assembly 2.

[0053] Further, refer to Figure 4, blind holes 162 are provided on opposite side walls of the groove 1161, and the two blind holes 162 cooperate with the atomization top seat 115 to form two liquid collecting cavities 16; wherein, whether a blind hole 163 is provided on the surface of the atomization top seat 115 close to the atomization base 116 is designed as required. That is to say, in the width direction of the atomization base 116, the two liquid collecting cavities 16 are arranged on opposite sides of the atomization cavity 111. Preferably, in the width direction of the atomization base 116, the two liquid collecting cavities 16 are symmetrically arranged on opposite sides of the atomization cavity 111. Among them, the width direction of the atomization base 116 is the same as the width direction of the atomization component 1.

[0054] It can be understood that the shape and size of the liquid absorbing member 161 are set in cooperation with the shape and size of the liquid collecting cavity 16 so that the liquid absorbing member 161 fills the liquid collecting cavity 16; the shape and size of the liquid absorbing member 161 and the liquid collecting cavity 16 can be designed as required, as long as the leakage can be absorbed. Preferably, the cross-sections of the liquid collecting cavity 16 and the liquid absorbing member 161 are both regular polygons; more preferably, the cross-section of the liquid collecting cavity 16 and / or the liquid absorbing member 161 is circular. The product structure of the liquid absorbing member 161 with a circular cross-section is simple, the production waste is less, and the processing efficiency is high; when the liquid absorbing member 161 with a circular cross-section is assembled into the liquid collecting cavity 16, there is no need for special alignment and clearance avoidance, the process is simple, and the assembly cost is reduced; and in the same structural space, the liquid storage volume of the liquid absorbing member 161 with a circular cross-section can be greatly increased compared with the sheet-shaped liquid absorbing member 161.

[0055] The top surface of the liquid collection cavity 16 is not lower than the atomization surface 121 of the atomization core 12; and / or, the bottom surface of the liquid collection cavity 16 is not higher than the bottom surface of the atomization cavity 111, so that the height of the liquid collection cavity 16 is greater than the height of the atomization cavity 111, having a larger capacity for storing leaked liquid. The bottom surface of the liquid collection cavity 16 not being higher than the bottom surface of the atomization cavity 111 is conducive to the leaked liquid in the atomization cavity 111 entering the liquid collection cavity 16. The top surface of the liquid collection cavity 16 not being lower than the atomization surface 121 of the atomization core 12 ensures that whether the end surface of the atomization top seat 115 close to the atomization bottom seat 116 is a plane, and the liquid collection cavity 16 formed by the cooperation of the end surface of the atomization top seat 115 close to the atomization bottom seat 116 and the blind hole 162, or the liquid collection cavity 16 formed by the cooperation of the blind hole 163 provided on the surface of the atomization top seat 115 close to the atomization bottom seat 116 and the blind hole 162, the height of the liquid collection cavity 16 is equal to or greater than the height of the atomization cavity 111, improving the liquid storage capacity of the liquid collection cavity 16. By setting the bottom surface of the liquid collection cavity 16 to be not higher than the bottom surface of the atomization cavity 111 and the top surface of the liquid collection cavity 16 to be not lower than the atomization surface 121 of the atomization core 12, the space in the length direction of the atomization cavity 111 is fully utilized, the liquid storage capacity of the liquid collection cavity 16 is increased as much as possible, and the space occupied by the liquid collection cavity 16 in the thickness direction of the atomization component 1 is reduced, which is conducive to the thinning of the electronic atomization device. It can be understood that the length direction of the atomization cavity 111 is the same as the length direction of the atomization component 1. Preferably, the port of the blind hole 162 is not lower than the atomization surface 121 of the atomization core 12, and the bottom surface of the blind hole 162 is lower than the bottom surface of the atomization cavity 111.

[0056] By providing a first through hole 164 communicating the liquid collection cavity 16 and the atomization cavity 111 on the common side wall of the liquid collection cavity 16 and the atomization cavity 111, the leaked liquid in the atomization cavity 111 is drained into the liquid collection cavity 16. The bottom surface or the lowest point of the first through hole 164 is not higher than the bottom surface of the atomization cavity 111. Utilizing the principle that liquid naturally flows from a higher place to a lower place, it is conducive to the quick diversion of the leaked liquid in the atomization cavity 111 to the liquid collection cavity 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 collection cavity 16 and the atomization cavity 111 can be connected. The dimension of the first through hole 164 in the direction perpendicular to the length direction of the atomization component 1 is 0.5 mm - 1.0 mm; preferably, 0.8 mm. It can be understood that a groove or notch communicating the liquid collection cavity 16 and the atomization cavity 111 can also be provided on the common side wall of the liquid collection cavity 16 and the atomization cavity 111 to achieve the connection between the liquid collection cavity 16 and the atomization cavity 111, which is specifically designed according to needs. When a notch communicating the liquid collection cavity 16 and the atomization cavity 111 is provided on the common side wall of the liquid collection cavity 16 and the atomization cavity 111, the bottom surface of the notch is lower than the bottom surface of the atomization cavity 111, and the dimension of the notch in the length direction of the atomization component 1 is the same as the height of the blind hole 162, so that when there is more leaked liquid in the atomization cavity 111, it can be quickly diverted to the liquid collection cavity 16.

[0057] See Figure 3, an air exchange groove 112 is provided on the outer surface of one end of the atomizing base 11 close to the liquid storage cavity 13. One end of the air exchange groove 112 is communicated with the liquid storage cavity 13, which is used to exchange air for the liquid storage cavity 13 to achieve the air pressure balance between the liquid storage cavity 13 and the external atmosphere; a liquid storage groove 113 is provided on the outer surface of the end of the atomizing base 11 far from the liquid storage cavity 13; a drainage groove 114 is provided on the outer surface of the middle part of the atomizing base 11. One end of the drainage groove 114 is communicated with the other end of the air exchange groove 112, and the other end of the drainage groove 114 is communicated with the liquid storage groove 113. Since there may be an aerosol-forming matrix leaking from the liquid storage cavity 13 in the air exchange groove 112, when the aerosol-forming matrix in the air exchange groove 112 accumulates to a certain volume, it will leak out, resulting in liquid leakage. The liquid leakage formed by the air exchange groove 112 is guided to the liquid storage groove 113 through the drainage groove 114, and the liquid storage groove 113 stores the liquid leakage to avoid the influence of the liquid leakage on the power supply assembly 2. In one embodiment, a second through hole 165 (as shown in Figure 2b ) is provided on the side wall of the liquid collection cavity 16. The second through hole 165 communicates the liquid storage groove 113 with the liquid collection cavity 16 to guide the liquid leakage in the liquid storage groove 113 to the liquid collection cavity 16, and then be absorbed by the liquid absorption member 161 in the liquid collection cavity 16, thereby avoiding sucking the liquid leakage and preventing the liquid leakage from leaking into the power supply assembly 2, so as to affect the performance of the power supply assembly 2. Among them, the second through hole 165 and the first through hole 164 provided on the side wall of the blind hole 162 are arranged in a staggered manner. The cross-sectional shape of the second through hole 165 can be circular, square, strip-shaped or other shapes, which is 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 strip-shaped, 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 collection cavity 16 is designed according to needs; preferably, the second through hole 165 is located in the middle of the height direction of the liquid collection cavity 16, that is, the second through hole 165 is not at the uppermost or lowermost position of the liquid collection cavity 16. It can be understood that since the second through hole 165 communicates the liquid storage groove 113 with the liquid collection cavity 16, and most of the liquid leakage in the liquid storage groove 113 comes from the air exchange groove 112 on the atomizing top base 115, therefore, setting it in the middle can avoid structural conflict with the first through hole 164 while realizing liquid conduction; at the same time, the staggered arrangement of the second through hole 165 and the first through hole 164 can introduce the liquid leakage into the liquid absorption member 161 in the liquid collection cavity 16 better and faster, reducing the possibility of liquid leakage caused by the local liquid absorption saturation of the liquid absorption member 161.

[0058] See Figure 3, specifically, the air exchange groove 112 is provided on the outer surface of the atomization top seat 115, and the drainage groove 114 and the liquid storage groove 113 are provided on the outer surface of the atomization base 116. Among them, the width and / or depth of one end of the drainage groove 114 close to the air exchange groove 112 is less than the width and / or depth of one end of the drainage groove 114 close to the liquid storage groove 113, that is, the width and / or depth of the drainage groove 114 increases in a gradient along the direction from the air exchange groove 112 to the liquid storage groove 113, and the specific setting of the gradient is designed according to needs. The width of the end of the drainage groove 114 far from the liquid storage chamber 13 is 0.2 mm - 1.5 mm, and the depth is 0.2 mm - 1.5 mm; the width of the end of the drainage groove 114 close to the liquid storage chamber 13 is 0.2 mm - 1.5 mm, and the depth is 0.2 mm - 1.5 mm. 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 end of the drainage groove 114 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 atomization seat 11, so that the drainage groove 114 is easy to form, and has a smooth transition with the housing 10, improving the assembly reliability and the yield rate.

[0060] By setting the width and / or depth of one end of the drainage groove 114 close to the air exchange groove 112 to be less than the width and / or depth of one end of the drainage groove 114 close to the liquid storage groove 113, when the liquid in the air exchange groove 112 on the outer surface of the atomization top seat 115 flows to the gap between the atomization top seat 115 and the atomization base 116, the drainage groove 114 on the atomization base 116 drains it into the liquid storage groove 113, preventing the liquid leakage formed by the air exchange groove 112 from climbing along the gap between the atomization seat 11 and the housing 10 to the air outlet channel 14 and causing suction liquid leakage. And due to the inclined surface design of the drainage groove 114, the liquid can more easily enter the liquid storage groove 113 for storage and is not easy to flow out of the liquid storage groove 113 in the reverse direction.

[0061] Please refer to Figures 5 - 7 , Figure 5 is a schematic longitudinal section view of an embodiment of the drainage groove in the atomization assembly provided by the present application, Figure 6 is Figure 2b a cross-sectional view of the atomization assembly along the B-B direction, Figure 7 is a schematic longitudinal section view of another embodiment of the drainage groove in the atomization assembly provided by the present application.

[0062] In one embodiment, the width of the drainage groove 114 gradually increases in a direction away from the liquid storage cavity 13, that is, the width of the drainage groove 114 gradually increases in a direction from the ventilation groove 112 to the liquid storage groove 113 (the gradient of the width of the drainage groove 114 increasing in the direction from the ventilation groove 112 to the liquid storage groove 113 is small), and one side of the longitudinal section of the drainage groove 114 is parallel to the length direction of the atomization base 11. Among them, the longitudinal section of the drainage groove 114 is obtained by profiling in a direction parallel to the width direction of the atomization assembly 1; the length direction of the atomization base 11 is the same as the length direction of the atomization assembly 1. Preferably, the longitudinal section shape of the drainage groove 114 is a right triangle or a right trapezoid (as Figure 5 shown). The depth of the drainage groove 114 gradually increases in a direction close to the central axis of the atomization assembly 1; the cross-sectional shape is triangular (as Figure 5 and Figure 6 shown), that is, the depth of the drainage groove 114 gradually increases from zero in the width direction in a direction close to the central axis of the atomization assembly 1. In this embodiment, the overall structure of the drainage groove 114 is in the shape of a triangular prism; by setting the drainage groove 114 in the shape of a triangular prism, the drainage groove 114 is easy to form, and a smooth transition between the drainage groove 114 and the housing 10 is achieved, improving the assembly reliability and the finished product rate. It can be understood that the cross-sectional shape of the drainage groove 114 can also be an isosceles trapezoid, a semi-circle, etc., and the longitudinal section shape of the drainage groove 114 can also be any other shape, and the cross-sectional shape and the longitudinal section shape of the drainage groove 114 are designed according to needs.

[0063] In another embodiment, as Figure 7 shown, the drainage groove 114 includes a plurality of sub-drainage grooves with 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 cavity 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 gradient of the width of the drainage groove 114 increasing in the direction from the ventilation groove 112 to the liquid storage groove 113 is large). 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 atomization base 11. Among them, the longitudinal sections of the first sub-drainage groove 1141 and the second sub-drainage groove 1142 are obtained by profiling in a direction parallel to the width direction of the atomization assembly 1. In this embodiment, the depths of the first sub-drainage groove 1141 and the second sub-drainage groove 1142 both gradually increase from zero in the width direction in a direction close to the central axis of the atomization assembly 1, so as to achieve a smooth transition between the drainage groove 114 and the housing 10 and improve the assembly reliability and the finished product rate.

[0064] Please refer to Figure 8 , Figure 8 which Figure 3 is a schematic structural diagram of the atomizing base provided from another angle.

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

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

[0067] It can be understood that the atomizing top base 115 and the atomizing bottom base 116 can be integrally formed or detachably connected; when the atomizing top base 115 and the atomizing bottom base 116 are integrally formed, the corresponding air exchange groove 112, drainage groove 114, and liquid storage tank 113 can be formed through one processing process and are interconnected.

[0068] Please refer to Figure 9 , Figure 9 which Figure 2b is a schematic assembly structure diagram of the atomizing base and the first seal in

[0069] See Figure 2b and Figure 9 Figure 9 , the atomization assembly 1 further 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 disposed on the top surface of the atomization top seat 115, and the side wall of the first seal 18 is disposed on the outer side surface of the atomization top seat 115. That is to say, the top wall of the first seal 18 is disposed on the top surface of the atomization seat 11, and the side wall of the first seal 18 is disposed on the outer side surface of the atomization seat 11. And the side wall of the first seal 18 covers the ventilation groove 112 disposed on the outer surface of the atomization 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 in the figure). The gap between the end face of the side wall of the first seal 18 close to the atomization base 116 and the top surface of the atomization base 116 is greater than or equal to 0.1 mm and less than or equal to 0.3 mm; preferably, 0.25 mm. It can be understood that the gap between the first seal 18 and the top surface of the atomization base 116 can better ensure the ventilation of the ventilation channel, and it can form a ventilation channel surrounding the atomization seat 11 to avoid poor ventilation caused by leakage and blockage.

[0070] See Figure 2b and Figure 9 Figure 9 , the groove 1161 on the atomization base 116 includes a first side wall and a second side wall disposed opposite to each other, 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 disposed on the first side wall and the second side wall of the groove 1161, and notches (not shown in the figure) are disposed on the third side wall and the fourth side wall of the groove 1161. The surface of the atomization top seat 115 close to the atomization base 116 is provided with a groove (not shown in the figure), and the groove on the atomization top seat 115 cooperates with the groove 1161 to form an installation cavity 110; the groove on the atomization top seat 115 includes a first side wall and a second side wall disposed opposite to each other, 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 disposed on the first side wall and the second side wall of the groove on the atomization top seat 115, and notches (not shown in the figure) are disposed on the third side wall and the fourth side wall of the groove on the atomization top seat 115. The notches on the third side wall and the fourth side wall of the groove on the atomization top seat 115 are correspondingly disposed with the notches on the third side wall and the fourth side wall of the groove 1161, and the notches on the atomization top seat 115 and the notches on the atomization base 116 cooperate with the housing 10 to form an air flow channel 19. That is, a part of the atomization core 12 is exposed to the air flow channel 19 through the notches on the atomization top seat 115 and the notches on the atomization base 116, so that the outside air carrying the aerosol atomized by the atomization core 12 flows through both sides of the atomization core 12 and enters the air outlet channel 14.

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

[0072] Vertical ribs 181 are provided on both sides of the first seal 18 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 included angle between the extending direction of the vertical ribs 181 and the central axis of the atomization assembly 1 is less than 90 degrees, that is, the extending direction of the vertical ribs 181 does not need to be parallel to the thickness and width directions of the atomization assembly 1; preferably, the extending direction of the vertical ribs 181 is parallel to the central axis direction of the atomization assembly 1, that is, the included angle between the two is 0 degrees. And the vertical ribs 181 are in contact with the housing 10; preferably, the length of the vertical ribs 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 atomization 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 assembly 1, therefore, the vertical ribs 181 need to be provided on both sides corresponding to the two channels respectively, that is, there are a total of 4 vertical ribs 181 in this embodiment.

[0073] Convex bones 1152 are provided on both sides of the atomization top base 115 corresponding to the air flow channel 19, and the convex bones 1152 extend along the height direction of the atomization top base 115; preferably, the convex bones 1152 extend along the edge line of the notch on the atomization top base 115; more preferably, convex bones 1152 are provided on both of the opposite two side lines of the notch on the atomization top base 115. It can be understood that the included angle between the extending direction of the convex bones 1152 and the central axis direction of the atomization assembly 1 is less than 90 degrees, that is, the extending direction of the convex bones 1152 does not need to be parallel to the thickness and width directions of the atomization assembly 1. Preferably, the included angle between the extending direction of the convex bones 1152 and the length direction of the atomization assembly 1 is greater than 0 degrees and less than 90 degrees; so that when the convex bones 1152 are in contact with the housing 10, the housing 10 can be supported in both the length and width directions of the atomization assembly 1, and the overall strength and rigidity of the housing 10 or the atomization assembly 1 can be improved. The gap between the convex bones 1152 and the housing 10 is 0 - 0.03 mm. The height direction of the atomization top base 115 is the same as the length direction of the atomization 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 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.

[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 Figures 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.

[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 seal 18, and the first seal 18 is in interference fit with the housing 10 through the first annular protrusion 182. The shape of the first annular protrusion 182 is arranged in cooperation with the cross-sectional shape of the side wall of the first seal 18. The interference amount between the major axis vertex of the first annular protrusion 182 and the housing 10 is a first value, and the interference amount between the minor 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 major axis vertex of the first annular protrusion 182 and the housing 10 is less than the interference amount between the minor 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, and it is only necessary to prevent the aerosol-forming matrix in the liquid storage cavity 13 from leaking.

[0080] In this embodiment, the cross-sectional shape of the housing 10 is elliptical, and the corresponding cross-sectional shape of the first seal 18 is also elliptical; see Figure 11 and Figure 12 , the A area is the major axis vertex of the side wall of the first seal 18, and the B area is the minor 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 housing 10 is not elliptical, there are still a major axis and a minor axis in the cross-section of the housing 10, and there are still a major axis and a minor axis in the cross-section of the corresponding first seal 18. It is only necessary to make the interference amount between the major axis vertex of the first annular protrusion 182 and the housing 10 less than the interference amount between the minor axis vertex of the first annular protrusion 182 and the housing 10.

[0081] Since the strength of the housing 10 in the thickness direction in the ultra-thin electronic atomization device is weaker than that of conventional products, the first seal 18 designed for sealing inside is more likely to be deformed by force, thus bringing the risk of weakening the sealing performance of the liquid storage cavity 13. By making the interference amount between the major axis vertex of the first annular protrusion 182 and the housing 10 less than the interference amount between the minor axis vertex of the first annular protrusion 182 and the housing 10, the force on the housing 10 corresponding to the major axis vertex of the first annular protrusion 182 is less than the force on the housing 10 corresponding to the minor axis vertex of the first annular protrusion 182; that is, the unilateral interference amount in the width direction is the same as that of conventional products, and the unilateral interference amount in the thickness direction is larger than the unilateral interference amount in the width direction, so as to make up for the sealing weakening caused by the deformation of the housing 10, ensure the overall sealing performance of the product, and avoid the leakage of the aerosol-forming matrix caused by the sealing failure of the liquid storage cavity 13.

[0082] Further, from the major axis vertex of the first annular protrusion 182 to the minor axis vertex of the first annular protrusion 182, the interference amount between the first annular protrusion 182 and the housing 10 gradually increases circumferentially along the first annular protrusion 182. That is to say, the force received by the housing 10 from the position corresponding to the major axis vertex of the first annular protrusion 182 to the position corresponding to the minor axis vertex of the first annular protrusion 182 gradually increases circumferentially along the housing 10, so that the force received by the housing 10 at the position corresponding to the major axis vertex of the first annular protrusion 182 is the smallest, and the force received by the housing 10 at the position corresponding to the minor axis vertex of the first annular protrusion 182 is the largest. In this way, the weakened seal caused by the deformation of the housing 10 is compensated, the overall sealing performance of the product is ensured, and the leakage of the aerosol generation matrix caused by the seal failure of the liquid storage cavity 13 is avoided. In one embodiment, the first annular protrusion 182 has two opposite major axis vertices and two opposite minor axis vertices. From any major axis vertex to one of the minor axis vertices, the interference amount between the first annular protrusion 182 and the housing 10 gradually increases circumferentially along the first annular protrusion 182.

[0083] In one embodiment, the side wall of the first seal 18 contacts the inner wall surface of the housing 10, and the interference fit with the housing 10 is achieved by providing the first annular protrusion 182 on the side wall of the first seal 18; by adjusting the protrusion height of the first annular protrusion 182, the adjustment of the interference amount between the first seal 18 and the housing 10 is achieved.

[0084] See Figure 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 circumferential direction 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 spaced apart; one end of the vertical rib 181 abuts against the first annular protrusion 182 away from the liquid storage cavity 13 among the two first annular protrusions 182, and the other end of the vertical rib 181 extends in a direction away from the first annular protrusion 182. The interference fit relationship between the two first annular protrusions 182 and the housing 10 both satisfies the above.

[0085] A third seal 1162 is provided at one end of the atomization base 116 away from the liquid storage cavity 13. The third seal 1162 is provided along the circumference of the atomization base 116 and contacts the housing 10 to achieve the seal between the atomization base 116 and the housing 10. The interference amount between the major axis vertex of the third seal 1162 and the housing 10 is smaller than the interference amount between the minor axis vertex of the third seal 1162 and the housing 10. Specifically, the setting method of the interference amount between the third seal 1162 and the housing 10 is the same as the setting method of the interference amount between the first seal 18 and the housing 10, and will not be elaborated here.

[0086] By making the interference between the major-axis vertex of the third seal 1162 and the housing 10 less than the interference between the minor-axis vertex of the third seal 1162 and the housing 10, the sealing weakening caused by the deformation of the housing 10 is further compensated to ensure the overall sealing performance of the product.

[0087] Continue to refer to Figure 10 , an air vent 117 is provided at one end of the atomization base 11 close to the air outlet passage 14; that is, an air vent 117 is provided on the atomization top base 115, and the two liquid supply channels 1151 are located on both sides of the air vent 117. The air vent 117 is communicated with the air outlet passage 14 and is also communicated with the atomization chamber 111 so that the aerosol atomized by the atomization core 12 flows out from the air outlet passage 14. The end of the air outlet passage 14 is embedded in the air vent 117; a part of the inner surface of the air vent 117 is attached to a part of the outer surface of the air outlet passage 14, and a liquid guiding rib 1171 is provided on another part of the inner surface of the air vent 117, that is, the liquid guiding rib 1171 is provided on the inner surface of the part of the air vent 117 where the air outlet passage 14 is not provided. A tip is formed on the side of the liquid guiding rib 1171 away from the inner surface of the air vent 117, and the distance between the tip and the inner surface of the air vent 117 is a third value H, and the third value H is greater than the wall thickness of the air outlet passage 14. In a specific embodiment, the third value H is 0.3 - 0.7 mm greater than the wall thickness of the air outlet passage 14; preferably, 0.5 mm.

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

[0089] In an embodiment, two liquid guiding ribs 1171 are symmetrically provided on the inner surface of the air vent 117, and the tips of the two liquid guiding ribs 1171 are spaced apart. In an example, the longitudinal section of the liquid guiding rib 1171 is triangular.

[0090] Since condensate forms quickly in the ultra-thin electronic atomization device, it is easy to accumulate into a liquid column in the air outlet channel 14, causing liquid leakage during suction. In this embodiment, the feature that the entire section of the air outlet channel 14 is smooth without corners facilitates the sliding down of condensate and reduces the accumulation of condensate. At the same time, two liquid guiding bones 1171 are symmetrically arranged on the inner surface of the ventilation hole 117, and the distance H between the tip of the liquid guiding bone 1171 and the inner surface of the ventilation hole 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 guiding bone 1171, it will spread and flow along the surface of the liquid guiding bone 1171 under the action of surface tension, and finally flow back to the atomization core 12 to be atomized again, eliminating the liquid accumulation in the air outlet channel 14 and thus preventing the occurrence of liquid leakage during suction. Moreover, an angle is formed between the top surface and the side surface of the liquid guiding bone 1171 to form a tip, and the tips of the two liquid guiding bones 1171 are arranged at intervals, that is, there is a gap between the two liquid guiding bones 1171, which is conducive to the mixing of the aerosol on both sides of the liquid guiding bone 1171 and improves the suction taste.

[0091] Specifically, the ventilation hole 117 includes a first region and a second region, and the second region is located on the side of the first region away from the air outlet channel 14. In the first region, the shape and size of the ventilation hole 171 remain unchanged, and the end of the air outlet channel 14 is embedded in the first region. In the second region, the size of the ventilation hole 171 gradually decreases along the direction away from the air outlet channel 14 to form a constricted structure, so as to facilitate the collection of condensate in the air outlet channel 14, and the liquid guiding bone 1171 is arranged in the second region. In one embodiment, the longitudinal cross-sectional shape of the liquid guiding bone 1171 is an isosceles triangle; the base of the isosceles triangle is located on the inner surface of the ventilation hole 117; the included 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 air outlet channel 14, and the length H of this side is 0.3 - 0.7 mm, preferably 0.5 mm, larger than the wall thickness of the air outlet channel 14. The shape and size of the liquid guiding bone 1171 can be designed according to needs, as long as it is conducive to eliminating the liquid accumulation in the air outlet channel 14 and the mixing of the aerosol on both sides.

[0092] Please refer to Figure 13 and Figure 14 , Figure 13 is Figure 10 the schematic assembly structure diagram of the atomization core and the atomization seat in Figure 14 is Figure 13 the schematic structure diagram of the second seal in

[0093] See Figure 10 , Figure 13 and Figure 14, a second seal 122 is provided between the top surface of the atomizing core 12 and the atomizing seat 11; that is, a second seal 122 is provided on the surface of the atomizing core 12 opposite to the atomizing surface 121. The second seal 122 is provided between the atomizing core 12 and the atomizing top seat 115. An opening 1221 is provided on the second seal 122 so that a part of the atomizing core 12 is exposed. The aerosol-forming substrate in the liquid storage cavity 13 enters the atomizing core 12 through the liquid supply 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 atomizing core 12, and the second surface of the second seal 122 contacts the atomizing top seat 115. A second annular protrusion 1222 is provided on the first surface and / or the second surface of the second seal 122. The second annular protrusion 1222 surrounds the opening 1221 for one week. By providing the second annular protrusion 1222 on the surface of the second seal 122, the surface seal is changed to a line seal, reducing the risk of seal failure caused by uneven pressing.

[0094] The cross-sectional shape of the second annular protrusion 1222 is arc-shaped. Preferably, the cross-sectional shape of the second annular protrusion 1222 is inferior arc-shaped. The cross-sectional shape of the second annular protrusion 1222 can be designed according to needs, as long as it can change the surface seal to a line seal.

[0095] Please refer to Figure 15 and Figure 16 , Figure 15 is a three-dimensional structural schematic diagram of a power supply component provided by the present application, Figure 16 is Figure 15 a cross-sectional view of the power supply component along the A-A direction.

[0096] The power supply component 2 includes a housing 201, a bracket 202, and an electrode connection component 203. A first accommodation cavity (not shown in the figure) is provided in the housing 201, and the bracket 202 is arranged in the first accommodation cavity. In this embodiment, the housing 201 further has a second accommodation cavity 2012 communicated with the first accommodation cavity for accommodating part of the atomizing component 1. During use, one end of the atomizing component 1 is inserted into the second accommodation cavity 2012 of the housing 201 and electrically connected to the power supply component 2 so that the power supply component 2 can supply power to the atomizing component 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, columnar with a square cross-section, etc.

[0097] The bracket 202 is used to mount 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 received in the first accommodation cavity 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 disposed on the top wall 2021, and one end of the electrode connection assembly 203 close to the atomization assembly 1 is exposed, so that when the atomization assembly 1 is inserted into the second accommodation cavity 2012, it can be electrically connected to the power supply assembly 2 through the electrode connection assembly 203. The side wall 2022 is disposed on the side of the top wall 2021 facing away from the atomization assembly 1 and extends along the length direction of the housing 201. In this embodiment, the side wall 2022 is disposed on the inner wall of the first accommodation cavity.

[0098] Please refer to Figure 17 , Figure 18 and Figure 19 , Figure 17 is a partial cross-sectional view of the power supply assembly provided by this application, Figure 18 is a schematic structural diagram of some components in the power supply assembly after being assembled, Figure 19 is a schematic structural diagram of the second circuit board, the reinforcement and a plurality of light-emitting elements after being 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] Among them, 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. Further, refer to Figure 19, the second circuit board 205 includes a main body portion 2051 and a first connection portion 2052 that are interconnected. The main body portion 2051 is used to carry circuits and circuit components, and the first connection portion 2052 is used to connect to the first circuit board 204. Among them, the second circuit board 205 can be a flexible printed circuit (FPC). The flexible printed circuit is a printed circuit board supported by a polyimide or polyester film substrate, which has high reliability and excellent flexibility. The flexible printed circuit has a thin thickness and good bendability. However, precisely because the FPC has good flexibility and small rigidity, the support for components such as light-emitting diodes (LED lights) disposed thereon is poor. During use, it may cause the light-emitting component 207 to be easily damaged and have a low service life.

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

[0103] Specifically, as Figure 19 shown, the first connection portion 2052 is bent at a certain angle α relative to the main body portion 2051 along the fold line B-B toward the side of the first circuit board 204. The bending angle α satisfies 90° < α ≤ 180°, so that the projection of the main body portion 2051 and the first circuit board 204 on the side wall 2022 of the bracket 202 partially overlaps, realizing the saving of 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 bent 180 degrees relative to the main body portion 2051 and then connected to the first circuit board 204. In some other embodiments, the first connection portion 2052 can also be in a straight connection state relative to the main body portion 2051 and connected to the first circuit board 204; that is, although the second circuit board 205 has bendability, the first connection portion 2052 and the main body portion 2051 are not bent in this embodiment.

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

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

[0106] The reinforcing member 206 is arranged on the surface of the main body portion 2051 close to the first circuit board 204, and the projections of the plurality of light-emitting elements 207 and the reinforcing member 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 reinforcing member 206 is arranged on the other side of the second circuit board 205 opposite to the position where the plurality of light-emitting elements 207 are located, and is used to strengthen the second circuit board 205 at the position where the plurality of light-emitting elements 207 are located. The reinforcing member 206 can be a material with a certain strength and stiffness, 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 stiffness and strength also meet the requirements of the reinforcing member 206. Considering factors such as cost, the reinforcing member 206 is preferably a steel sheet.

[0107] By arranging the reinforcing member 206 on the other side of the second circuit board 205 opposite to the position where the plurality of light-emitting elements 207 are located, the second circuit board 205 at the position where the plurality of light-emitting elements 207 are located can be strengthened, effectively improving the strength and stiffness of the second circuit board 205 at the position where the plurality of light-emitting elements 207 are located, and further preventing the damage of the light-emitting element 207 and improving the service life of the light-emitting element 207.

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

[0109] In one embodiment, the reinforcing member 206 can be fixed to the main body portion 2051. For example, the reinforcing member 206 can be fixed to the main body portion 2051 through an adhesive layer, and the material of the adhesive layer can be double-sided tape.

[0110] Furthermore, in this embodiment, as Figure 17 and Figure 18 shown, the power supply assembly 2 further includes a battery 208. The battery 208 is electrically connected to the first circuit board 204, so that the battery 208 can provide electrical energy for the atomization assembly 1. The battery 208 is installed on the bracket 202. The battery 208 is disposed on one side of the first circuit board 204 away from the top wall of the bracket 202, and is disposed on the surface of the main body portion 2051 away from the side wall 2022 of the bracket 202. A part of the reinforcing member 206 is clamped between the battery 208 and the main body portion 2051 to be disposed on the main body portion 2051 through a tight fit. The reinforcing member 206 is clamped between the battery 208 and the main body portion 2051, effectively utilizing the tight fit between the components in the power supply assembly 2, and can further enhance the fixation of the reinforcing member 206.

[0111] In one embodiment, as Figure 18 and Figure 19 shown, the first connecting portion 2052 has a bent portion 2052a and a straight plate portion 2052b. The main body portion 2051, the bent portion 2052a, and the straight plate portion 2052b are connected in sequence. The bent portion 2052a is connected to one end of the main body portion 2051 close to the atomization assembly 1, and is bent at a certain angle α toward the side of the first circuit board 204 with respect to the main body portion 2051. The straight plate portion 2052b is disposed along the length direction of the outer shell 201 and is electrically connected to the first circuit board 204.

[0112] Among them, as Figure 17As shown, a part of the reinforcing member 206 is disposed between the battery 208 and the main body portion 2051, and another part of the reinforcing member 206 extends between the first circuit board 204 and the main body portion 2051. A part of the reinforcing member 206 is disposed between the battery 208 and the main body portion 2051 and is clamped by the battery 208 and the bracket, so that it can be kept stable; another part of the reinforcing member 206 extends between the first circuit board 204 and the main body portion 2051 and can be disposed in a suspended manner to support the main body portion 2051. One end of the reinforcing member 206 close to the atomizing assembly 1 is disposed close to the bending portion 2052a to limit the bent position of the second circuit board 205. Preferably, one end of the reinforcing member 206 close to the atomizing assembly 1 abuts against the concave portion of the bending portion 2052a.

[0113] Please refer to Figure 17 , in this embodiment, a plurality of light-emitting elements 207, the main body portion 2051, the reinforcing member 206, the straight plate portion 2052b, and the first circuit board 204 are sequentially stacked along the thickness direction of the housing 201, and the projection parts on the bracket 202 overlap. The bending portion 2052a connects the end of the main body portion 2051 close to the atomizing assembly 1 and the end of the straight plate portion 2052b close to the atomizing assembly 1. By sequentially stacking the respective elements along the thickness direction of the housing 201 and making the projection parts of the respective elements overlap on the bracket 202, the space in the thickness direction of the first accommodation cavity can be fully utilized, and the plurality of elements in the power supply assembly 2 can be orderly stacked in the first accommodation cavity, which is beneficial to reducing the waste of the space in the thickness direction of the first accommodation cavity, and thus beneficial to the thinning of the electronic atomization device.

[0114] In this embodiment, as Figure 18 shown, the power supply assembly 2 further includes a third circuit board 209 and a charging interface 210, and both the third circuit board 209 and the charging interface 210 are installed on the bracket 202. Among them, one end of the second circuit board 205 away from the atomizing assembly 1 has a second connection portion 2053, and the second connection 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 realize the charging of the battery 208 by the external component.

[0115] Please refer to Figure 20 , Figure 20 is a three-dimensional structural schematic diagram of the bracket provided by the present application.

[0116] See Figure 17 and Figure 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 Figure 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, Figure 17 and Figure 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 Figure 17As shown in the figure, a plurality of light-blocking holes 2111 are arranged at intervals on the astigmatic layer 211, and the plurality of light-blocking holes 2111 are arranged in a staggered manner with the plurality of light-shielding holes 2023, that is, the plurality of light-blocking holes 2111 are arranged in a staggered manner with the plurality of light-emitting elements 207. Specifically, the number of the light-blocking holes 2111 is one less than the number of the light-emitting elements 207, and each light-blocking hole 2111 is arranged at a corresponding position between two adjacent light-emitting elements 207. By arranging the light-blocking holes 2111 on the astigmatic layer 211, it is possible to further prevent light crosstalk and light leakage between adjacent light-emitting elements 207, and further make the brightness of the light emitted by the light-emitting elements 207 uniform.

[0120] The above are only some embodiments of the present application, and thus do not limit the protection scope of the present application.
