[0053] like Figures 2 to 4 As shown, further, in this embodiment, the power supply assembly includes a housing 10, a bracket 20, a battery cell 30 and a circuit board 40. The housing 10 is used to accommodate the bracket 20, the battery cell 30 and the circuit board 40. The bracket 20 is arranged in the housing 10 and can support the battery cell 30 and the circuit board 40. The battery cell 30 is arranged on the bracket 20, located at the lower part of the bracket 20, and can provide power to the atomizer. The circuit board 40 can be arranged on the bracket 20 and can be conductively connected to the battery cell 30.

[0054] Further, in this embodiment, the housing 10 is a cylindrical structure with an opening at one end. The housing 10 may be an injection molded part. Of course, it is understandable that in some other embodiments, the housing 10 may also be a metal housing. In this embodiment, a pressure relief hole 101 may be provided on the housing 10. The pressure relief hole 101 may release the air pressure in the housing 10 when an explosion occurs at the battery cell end, thereby avoiding further pressure increase, that is, reducing the explosion intensity.

[0055] like Figure 6 to Figure 7 As shown, further, in this embodiment, the bracket 20 is an insulating member, specifically, the bracket 20 can be an injection molded member, specifically, the bracket 20 can be made of plastic. Of course, it can be understood that in some other embodiments, the bracket 20 is not limited to plastic material, and can be ceramic or other insulating materials. The bracket 20 includes a bottom wall 21, a side wall 22, a first end wall 23 and a second end wall 24. The bottom wall 21 can be a long bottom wall, and the side wall 22 can be arranged on two opposite sides of the bottom wall 21. The side wall 22 can be a short side wall and can be integrally formed with the bottom wall 21. The first end wall 23 can be arranged at one end of the bottom wall 21, and the second end wall 24 can be arranged at the other end of the bottom wall 21. The second end wall 24 can be provided with an air inlet 241 that is connected to the atomizer for gas to enter the atomizer. The first end wall 23 can be arranged parallel to the second end wall 24. The bottom wall 21 , the side wall 22 , the first end wall 23 , and the second end wall 24 may be arranged to form a receiving space having an opening and capable of receiving the battery cell 30 and the circuit board 40 .

[0056] Further, in the present embodiment, the bracket 20 may further include a retaining wall 25, which is arranged in the receiving space along a direction transverse to the bottom wall 21, and divides the receiving space into a first receiving chamber 201 and a second receiving chamber 202. The first receiving chamber 201 may be used to accommodate the battery cell 30, and the second receiving chamber 202 may be used to accommodate the circuit board 40. In the present embodiment, the first receiving chamber 201 and the second receiving chamber 202 may be independently arranged, and the first receiving chamber 201 and the second receiving chamber 202 may be isolated from each other, so as to prevent the electrolyte of the battery cell 30 from corroding the circuit board 40, thereby improving the sensitivity of the airflow sensing device 50. In the present embodiment, the first receiving chamber 201 and the second receiving chamber 202 may both be in the shape of a rectangular parallelepiped, and the second receiving chamber 202 may be arranged side by side with the first receiving chamber 201, and the second receiving chamber 202 may be arranged near the end of the bracket 20 that contacts the atomizer A. The size of the second accommodating chamber 202 can be smaller than the size of the first accommodating chamber 201. Specifically, the length of the second accommodating chamber 202 is smaller than the length of the first accommodating chamber 201, thereby better preventing the electrolyte of the battery cell 30 from corroding the circuit board 40 and shortening the length of the sensing airway of the airflow sensing device 50, thereby improving the sensitivity of the airflow sensing device 50.

[0057] In this embodiment, a receiving groove 203 may be provided at one end of the first receiving cavity 201, and the receiving groove 203 may be communicated with the first receiving cavity 201, and may be used to receive the battery circuit board 32 provided at one end of the battery cell 30. In this embodiment, the shape and size of the receiving groove 203 may be adapted to the shape and size of the battery circuit board 32. Specifically, the receiving groove 203 may be a rectangular parallelepiped, and the size of the receiving groove 203 may be slightly larger than the size of the battery circuit board 32. Of course, it can be understood that in some other embodiments, the size of the receiving groove 203 may be comparable to the size of the battery circuit board 32.

[0058] In the present embodiment, a boss 26 may be further provided in the bracket 20. The boss 26 may be provided close to the retaining wall 25, may be located in the receiving groove 203, and may be provided protrudingly on the bottom wall 21, and may be used to support the cell conductive member 60 and may limit the pressing force of the cell circuit board 32 on the cell 30 on the cell conductive member 60. The shape of the boss 26 may be adapted to the shape of the cell circuit board 32. The boss 26 may be in the shape of a rectangular parallelepiped. Of course, it is understandable that in some other embodiments, the boss 26 may not be limited to being in the shape of a rectangular parallelepiped. The boss 26 may be integrally formed with the bottom wall 21. In the present embodiment, the boss 26 and the bottom wall 21 are integrally formed by injection molding.

[0059] In this embodiment, two opposite sides of the accommodating groove 203 may be provided with limiting notches 27, and the limiting notches 27 may be two, and the two limiting notches 27 may be opened on the side walls 22 at both ends of the boss 26. The limiting notches 27 may be used to limit the battery circuit board 32, and may also facilitate the accommodating groove 203 to accommodate a longer battery circuit board 32, thereby increasing the applicable range of the accommodating groove 203.

[0060] In this embodiment, two steps 28 may be spaced apart on the boss 26, and the steps 28 may protrude from the contact surface between the boss 26 and the cell circuit board 32, and may also be used to limit the pressing force of the cell circuit board 32 on the cell conductive member 60. It is understandable that in other embodiments, the steps 28 may be omitted.

[0061] In this embodiment, a pressure relief port 221 may be provided on the side wall 22 corresponding to the first accommodation cavity 201; the pressure relief port 221 may be connected to the pressure relief hole 101 on the housing 10. When an explosion occurs at the cell end, the air pressure may be released from the pressure relief port 221 through the pressure relief hole, thereby avoiding further pressure increase, that is, reducing the explosion intensity. In this embodiment, the pressure relief port 221 may be rectangular. Of course, it is understandable that in other embodiments, the pressure relief port 221 may not be limited to a rectangular shape.

[0062] In this embodiment, a thin wall 222 may be provided at the pressure relief port 221. The thickness of the thin wall 222 is less than the thickness of the side wall 22, and the size may be smaller than the size of the pressure relief port 221. In this embodiment, the thin wall 222 may be rectangular, and the length may be less than the length of the pressure relief port 221. The thin wall 222 may be located in the middle of the pressure relief port 221, and a gap may be left between the thin wall 222 and the side walls on both sides of the pressure relief port 221 to allow the gas pressure in the first accommodation chamber 201 to be discharged. The thin wall 222 may allow the pressure relief port 221 to be staggered with the pressure relief hole 101 on the housing 10, and may ensure that the battery cell 30 is partially exposed to avoid a short circuit in the battery cell 30. The outer wall surface of the thin wall 222 may form a gas storage cavity with the housing 10 of the power supply assembly A, thereby storing gas, and the gas storage cavity may be connected to the pressure relief hole 101 on the housing 10. The gas storage chamber can increase the gas flow area and gas flow rate, thereby enabling quick and effective pressure release, thereby avoiding further pressure increase in the first accommodating chamber 201, thereby reducing the intensity of the explosion.

[0063] In this embodiment, a pressure relief hole 215 for pressure relief in communication with the second accommodating chamber 202 can be arranged on the bottom wall 21 arranged corresponding to the second accommodating chamber 202. The pressure relief hole 215 can be arranged close to the second end wall 24 and can be used to drive the airflow sensing device 50 to start normally. In actual use, the airflow sensing device 50 generates a trigger signal when a change in air pressure is detected. The existence of the pressure relief hole 215 enables the space where the airflow sensing device 50 is located to be connected to the outside world, and the airflow sensing device 50 is started by the change in negative pressure and atmospheric pressure during suction, and the start-up accuracy is higher. If the space is a closed space, the amplitude of the vibration membrane in the airflow sensing device 50 is not that large, and the start-up is not sensitive.

[0064] like Figure 5 As shown, further, in this embodiment, the battery cell 30 is accommodated in the first accommodation chamber 201, and the battery cell 30 is a rechargeable battery, which can be powered by an external power supply, so as to continuously provide power to the atomizer, thereby improving the cyclicity of the power supply component and reducing resource waste.

Specifically, the cell conductive member 60 may be integrally formed with the bracket 20 by injection molding, so that no additional insulating member is required to wrap the cell conductive member 60, thereby improving assembly efficiency and safety reliability, and facilitating automated production. In this embodiment, the cell conductive member 60 may be inserted through the bottom wall 21 and disposed between the first accommodating cavity 201 and the second accommodating cavity 202. Specifically, the cell conductive member 60 may be inserted through the boss 26 and the retaining wall 25, and may abut against the circuit board 40 and the cell 30, respectively, thereby conductively connecting the circuit board 40 and the cell 30. The contact method may reduce welding and parts, thereby facilitating automated production.

By arranging the first deformable portion 63 and the second deformable portion 64, the entire cell conductive member 60 can have an elastic deformation space, so that the first conductive contact portion 61 and the second conductive contact portion 62 of the cell conductive member 60 can form better contact with the corresponding positions of the cell 30 and the circuit board 40, respectively.

[0073] The first support portion 65 and the second support portion 66 can be arranged side by side and in parallel at both ends of the connecting portion 67.

[0096] like Figure 5 , Fig.11 ,and Fig.12As shown, further, in this embodiment, the power supply assembly may also include a first seal 80, which may cooperate with the bracket 20 and may be arranged corresponding to the airflow sensing device 50. Specifically, in this embodiment, the first seal 80 may be arranged at the opening of the second accommodating cavity 202 of the bracket 20 and be crimped onto the circuit board 40. In this embodiment, the first seal 80 may be a silicone member. Of course, it can be understood that in some other embodiments, the first seal 80 may not be limited to a silicone member. In this embodiment, the longitudinal section of the first seal 80 may be square, and its shape and size may be adapted to the second accommodating cavity 202.

[0097] Further, in the present embodiment, the first sealing member 80 includes an elastic body 81, and the shape and size of the elastic body 81 can be adapted to the second accommodating chamber 202. In the present embodiment, the first sealing member 80 can be provided with a first opening 82, a second opening 83, and a fluid channel 84 connecting the first opening 82 and the second opening 83. The first opening 82 can be located on the elastic body 81 and arranged close to the second end wall 24, and is communicated with the air inlet 241 on the second end wall 24. The first opening 82 can allow airflow to flow out and flow into the air inlet 241 of the second end wall 24, and can allow condensate to flow in if there is condensate. The second opening 83 can be arranged on the elastic body 81 and arranged close to the baffle wall 25. The second opening 83 can be communicated with the airflow hole 401 on the circuit board 40, and further communicated with the airflow sensing device 50. In this embodiment, the cross-sectional area of ​​the second opening 83 may be larger than the cross-sectional area of ​​the airflow hole 401 on the circuit board 40, so that when a slight misalignment occurs during installation, the normal operation of the airflow sensing device 50 is not affected. Specifically, the second opening 83 and the airflow hole 401 of the circuit board 40 may be circular holes, and the aperture of the second opening 83 may be larger than the aperture of the airflow hole 401 of the circuit board 40. The fluid channel 84 may connect the first opening 82 and the second opening 83. When the user inhales, the gas may pass through the airflow sensing device 50 and enter the second opening from the airflow hole 401 of the circuit board 40, and then pass through the fluid channel to be output from the second opening 83 to the air inlet 241 of the second end wall 24, so that the airflow sensing device 50 is in a negative pressure state. Condensate may be output from the air inlet 241 into the first opening 82 and into the fluid channel 84, and may be stored in the fluid channel 84. In this embodiment, the fluid channel can be designed so that the path of the condensate flowing from the first opening 82 through the fluid channel 84 into the second opening 83 is longer than the path of the airflow flowing from the second opening 83 through the fluid channel 84 to the first opening 82, that is, the fluid channel has different flow resistances for different flow directions, so that the airflow can flow normally to the first opening 82 to achieve the normal operation of the airflow sensing device 50, while the condensate is difficult to flow to the second opening 83, thereby preventing the condensate from corroding the airflow sensing device 50 and the circuit board 40.

[0098] Further, in the present embodiment, the fluid channel 84 includes a main channel 841 and at least one reflux channel 842. The main channel 841 can be centrally arranged and can be distributed in a straight line, one end of which is connected to the first opening 82, and the other end of which is connected to the second opening 83. Of course, it can be understood that in some other embodiments, the main channel 841 is not limited to being centrally arranged and is not limited to being distributed in a straight line. There can be multiple reflux channels 842, and multiple reflux channels 842 can be arranged side by side on both opposite sides of the main channel 841. Of course, it can be understood that in some other embodiments, there can be only one reflux channel 842. The reflux channel 842 can be connected to the main channel 841, which can increase the fluid path, thereby reducing the reflux of condensate to the circuit board 40, and preventing the condensate from contaminating the circuit board 40 and the airflow sensing device 50. In this embodiment, the reflux channel 842 can be tilted toward the second opening 83 and can form a set angle with the main channel 841. In this embodiment, the set angle can be an acute angle. Specifically, the set angle can be 30 to 60 degrees, preferably 45 degrees. By tilting the reflux channel 842 at an acute angle relative to the longitudinal axis of the main channel 841, the structural space can be optimized.

[0099] Further, in the present embodiment, the reflux channel 842 includes a flow portion 8421, a return portion 8422, and a connecting portion 8423. The flow portion 8421 may be connected to the main channel 841, and the condensate may flow from the main channel 841 into the flow portion 8421. The return portion 8422 may be connected to the main channel 841 and the flow portion 8421, and the return portion 8422 and the flow portion 8421 may be arranged in a straight line, and the flow portion 8421 and the return portion 8422 may be arranged in parallel. Of course, it can be understood that in some other embodiments, the return portion 8422 and the flow portion 8421 may not be limited to being arranged in a straight line, but may also be arranged in a curve. In some other embodiments, the flow portion 8421 and the return portion 8422 may not be limited to being arranged in parallel, but may also be distributed in an eight-shaped shape. The connecting portion 8423 may be used to connect the flow portion 8421 and the return portion 8422. The condensate may flow from the flow portion 8421 and then flow to the return portion 8422 through the connecting portion 8423 , and then return to the main channel 841 from the return portion 8422 .

[0100] Further, in this embodiment, the first sealing member 80 may be provided with a through hole 85, and the through holes 85 may be four and may be distributed at the four corners of the elastic body 81. The through hole 85 may be provided through the elastic body 81 along the thickness direction of the elastic body 81, and may be used for screws to pass through, so that the screws can connect and fix the first sealing member 80 and the bracket 20. In this embodiment, the through hole 85 may also be used for ventilation.

[0101] Further, in the present embodiment, a pressure relief groove 86 is provided on the first sealing member 80, and the pressure relief groove 86 can be communicated with the fluid channel 84. In the present embodiment, specifically, the pressure relief groove 86 can be arranged near the second opening 83, one end of which can be communicated with the fluid channel 84, and the other end can be communicated with one of the via holes 85. The function of the pressure relief groove 86 is that when the user does not inhale, the airflow sensing device 50 needs to stop working, but since the flow resistance of the fluid channel 84 flowing from the first opening 82 to the second opening 83 is very large, it is difficult for the airflow to flow back to the airflow sensing device 50. At this time, the pressure relief groove 86 can replenish the air pressure to relieve the negative pressure state of the airflow sensing device 50, thereby ensuring the normal operation of the airflow sensing device 50.

[0102] Further, in the present embodiment, a positioning protrusion 87 may be provided on the first sealing member 80, and the positioning protrusion 87 may be provided on a side of the elastic body 81 opposite to the airflow sensing device 50, and may be positioned in coordination with the airflow sensing device 50. In the present embodiment, when the first sealing member 80 is crimped onto the circuit board 40, the positioning protrusion 87 may be pressed onto the airflow hole 401 on the circuit board 40. In the present embodiment, the second opening 83 may be formed in the positioning protrusion 87. In the present embodiment, a sealing rib 871 may be provided on the protruding end surface of the positioning protrusion 87, and the sealing rib 871 may be provided protruding toward the circuit board 40, and may be used to seal the gap between the second opening 83 and the circuit board 40.

[0103] Furthermore, in the present embodiment, a sealing ring 88 for sealing in cooperation with the second sealing member 90 may be provided on the first sealing member 80 .

Specifically, the second seal 90 may be arranged at the second accommodating chamber 202, and may be pressed on the first seal 80, and may be connected and fixed to the bracket 20 by setting screws. By sequentially arranging the first seal 80 and the second seal 90 from the inside to the outside at the second accommodating chamber 202, the second accommodating chamber 202 may be sealed to form a closed space, and the electrolyte leakage of the battery cell in the first accommodating chamber 201 may be prevented from contaminating the circuit board 40 and the airflow sensing device 50 in the second accommodating chamber 202. In this embodiment, the second seal 90 includes a body 91, a first crimping structure 92 arranged on one side of the body 91 and protruding toward the second accommodating chamber 202, and a second crimping structure 93 arranged on one side of the body 91 and protruding toward the boss 26. The first crimping structure 92 may be columnar, and may be four, and may be spaced and distributed at the four corners of the body 91. Of course, it can be understood that in some other embodiments, the first crimping structure 92 may not be limited to four. The four first crimping structures 92 may be arranged one by one corresponding to the through holes 85 on the first seal 80, and may be inserted from the through holes 85 and pressed on the circuit board 40.

In this embodiment, the first crimping structure 92 may include a first crimping portion 921 and a second crimping portion 922 in a columnar shape, and both the first crimping portion 921 and the second crimping portion 922 may be pressed on the circuit board 40. The second crimping portion 922 may be protrudingly arranged on the outer side wall of the first crimping portion 921, thereby increasing the contact area between the first crimping structure 92 and the circuit board 40, so that the circuit board 40 can be stably pressed. In this embodiment, the second crimping structure 93 is block-shaped and can be crimped to one end of the circuit board 40 connected to the battery cell 30, so that the conductive sheet 60 and the circuit board 40 can be fully in contact. In this embodiment, there can be two second crimping structures 93, and the two second crimping structures 93 can be spaced apart.

[0106] Furthermore, in this embodiment, the power supply assembly may also include a sealing cover 100 , which may be a silicone member and may be sleeved on the top of the bracket 20 to seal the gap between the bracket 20 and the housing 10 .
