[0051] Figure 1 Some preferred embodiments of the electronic atomization device of the present invention are shown. In this embodiment, the electronic atomization device includes an atomizer A and a power supply component B; the atomizer A can be used to heat an atomization medium, such as e-liquid. The power supply component B can be mechanically and / or electrically connected to the atomizer A and can supply electrical energy to the atomizer A.

[0052] As Figures 2 to 4 shown, further, in this embodiment, the power supply component 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 disposed in the housing 10 and can support the battery cell 30 and the circuit board 40. The battery cell 30 is disposed on the bracket 20 and is located at the lower part of the bracket 20 and can supply electrical energy to the atomizer. The circuit board 40 can be disposed on the bracket 20 and can be electrically connected to the battery cell 30.

[0053] Further, in this embodiment, the housing 10 is a cylindrical structure with an opening at one end. The housing 10 can be an injection-molded part. Of course, it can be understood that in some other embodiments, the housing 10 can also be a metal housing. In this embodiment, a pressure relief hole 101 can be provided on the housing 10. The pressure relief hole 101 can release the air pressure in the housing 10 when an explosion occurs at the battery cell end, thereby avoiding continuous pressure increase, that is, reducing the explosion intensity.

[0054] As Figures 6 to 7As shown, further, in this embodiment, the bracket 20 is an insulating member. Specifically, the bracket 20 can be an injection-molded part, and specifically, the bracket 20 can be made of plastic material. Of course, it can be understood that in some other embodiments, the bracket 20 is not limited to plastic material and can be made of ceramic or other insulating materials. The bracket 20 includes a bottom wall 21, side walls 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 walls 22 can be disposed on two opposite sides of the bottom wall 21. The side walls 22 can be short side walls and can be integrally formed with the bottom wall 21. The first end wall 23 can be disposed at one end of the bottom wall 21, and the second end wall 24 can be disposed at the other end of the bottom wall 21. An air inlet hole 241 communicating with the atomizer for gas to enter the atomizer can be provided on the second end wall 24. The first end wall 23 can be disposed parallel to the second end wall 24. The bottom wall 21, side walls 22, first end wall 23, and second end wall 24 can enclose a receiving space having an opening and capable of receiving the battery cell 30 and the circuit board 40.

[0055] Further, in this embodiment, the bracket 20 may further include a partition wall 25. The partition wall 25 is disposed in the receiving space along a direction transverse to the bottom wall 21, dividing the receiving space into a first accommodation cavity 201 and a second accommodation cavity 202. The first accommodation cavity 201 can be used to accommodate the battery cell 30, and the second accommodation cavity 202 can be used to accommodate the circuit board 40. In this embodiment, the first accommodation cavity 201 and the second accommodation cavity 202 can be independently provided and can be isolated from each other, so as to prevent the electrolyte of the battery cell 30 from corroding the circuit board 40, and thus improve the sensitivity of the air flow sensing device 50. In this embodiment, both the first accommodation cavity 201 and the second accommodation cavity 202 can be in a cuboid shape, and the second accommodation cavity 202 can be arranged side by side with the first accommodation cavity 201. The second accommodation cavity 202 can be disposed close to the end of the bracket 20 in contact with the atomizer A. The size of the second accommodation cavity 202 can be smaller than the size of the first accommodation cavity 201. Specifically, the length of the second accommodation cavity 202 is less than the length of the first accommodation cavity 201, so as to better prevent the electrolyte of the battery cell 30 from corroding the circuit board 40 and shorten the sensing air passage length of the air flow sensing device 50, thereby improving the sensitivity of the air flow sensing device 50.

[0056] In this embodiment, a receiving groove 203 may be provided at one end of the first receiving cavity 201. The receiving groove 203 may communicate with the first receiving cavity 201 and is configured to receive a battery cell circuit board 32 disposed 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 cell circuit board 32. Specifically, the receiving groove 203 may be in the shape of a cuboid, and the size of the receiving groove 203 may be slightly larger than the size of the battery cell circuit board 32. Of course, it can be understood that in some other embodiments, the size of the receiving groove 203 may be equivalent to the size of the battery cell circuit board 32.

[0057] In this embodiment, a boss 26 may further be provided in the bracket 20. The boss 26 may be disposed close to the blocking wall 25, located in the receiving groove 203, and protrude from the bottom wall 21. It is configured to support the battery cell conductive member 60 and limit the pressing force of the battery cell circuit board 32 on the battery cell 30 against the battery cell conductive member 60. The shape of the boss 26 may be adapted to the shape of the battery cell circuit board 32. The boss 26 may be in the shape of a cuboid. Of course, it can be understood that in some other embodiments, the boss 26 may not be limited to the shape of a cuboid. The boss 26 may be integrally formed with the bottom wall 21. In this embodiment, the boss 26 and the bottom wall 21 are integrally formed by injection molding.

[0058] In this embodiment, limiting notches 27 may be provided on two opposite sides of the receiving groove 203. There may be two limiting notches 27, and the two limiting notches 27 may be formed on the side walls 22 at both ends of the boss 26. The limiting notches 27 are configured to limit the battery cell circuit board 32 and also facilitate the receiving groove 203 to receive a battery cell circuit board 32 with a longer length, thereby increasing the applicable range of the receiving groove 203.

[0059] In this embodiment, two steps 28 may be provided at intervals on the boss 26. The steps 28 may protrude from the contact surface between the boss 26 and the battery cell circuit board 32 and are also configured to limit the pressing force of the battery cell circuit board 32 on the battery cell conductive member 60. It can be understood that in other embodiments, the steps 28 may be omitted.

[0060] In this embodiment, a pressure relief port 221 may be provided on the side wall 22 corresponding to the first receiving cavity 201. The pressure relief port 221 may communicate with a pressure relief hole 101 on the outer shell 10. When an explosion occurs at the battery cell end, the air pressure can be released from the pressure relief port 221 through the pressure relief hole, thereby avoiding continuous pressure increase, that is, reducing the explosion intensity. In this embodiment, the pressure relief port 221 may be rectangular. Of course, it can be understood that in some other embodiments, the pressure relief port 221 may not be limited to the shape of a rectangle.

[0061] 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 that of the side wall 22, and its size may be smaller than that of the pressure relief port 221. In this embodiment, the thin wall 222 may be rectangular, and its length may be less than that 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 is left between the thin wall 222 and the side walls on both sides of the pressure relief port 221 for the air pressure in the first accommodation cavity 201 to be discharged. Through the thin wall 222, the pressure relief port 221 and the pressure relief hole 101 on the housing 10 may be arranged staggeredly, and it can be ensured that the core 30 is exposed, avoiding short circuit of the core 30. A gas storage cavity may be formed between the outer wall surface of the thin wall 222 and the housing 10 of the power supply component A, and then gas can be stored. The gas storage cavity may communicate with the pressure relief hole 101 on the housing 10. Through the gas storage cavity, the gas passing area and the gas passing volume can be increased, and then the pressure can be released quickly and effectively, so as to avoid continuous pressure increase in the first accommodation cavity 201, and further reduce the intensity of explosion.

[0062] In this embodiment, a pressure relief through hole 215 communicating with the second accommodation cavity 202 for pressure relief may be provided on the bottom wall 21 corresponding to the second accommodation cavity 202. The pressure relief through hole 215 may be arranged close to the second end wall 24 and can be used to drive the air flow sensing device 50 to start normally. During actual use, the air flow sensing device 50 generates a trigger signal when detecting a change in air pressure. The existence of the pressure relief through hole 215 makes the space where the air flow sensing device 50 is located communicate with the outside, and it is started by the negative pressure during suction and the change in atmospheric pressure, with higher starting accuracy. If it is a closed space inside, the amplitude of the vibration membrane in the air flow sensing device 50 is not large enough, and there will be a phenomenon of insensitive starting.

[0063] As Figure 5 shown, further, in this embodiment, the core 30 is accommodated in the first accommodation cavity 201. The core 30 is a rechargeable battery and can be powered by an external power supply, so as to continuously supply electric energy to the atomizer, and further improve the recyclability of the power supply component and reduce resource waste. In this embodiment, the core 30 may include a core body 31 and a core circuit board 32. The core circuit board 32 may be arranged at one end of the core body 31 and may be connected to the core body 31 by arranging leads 33. The core body 31 may be accommodated in the first accommodation cavity 201, and the core circuit board 32 may be accommodated in an accommodation groove 203 at one end of the first accommodation cavity 201, and both ends may be clamped on the limit notch 27. The core circuit board 32 may be electrically connected to the circuit board 40 through the core conductive member 60.

[0064] Further, in this embodiment, the circuit board 40 is received in the second receiving cavity 202. The power supply assembly further includes an airflow sensing device 50, which can be disposed in the second receiving cavity 202 and can be electrically connected to the circuit board 40. An airflow hole 401 for airflow to flow into the airflow sensing device 50 can be provided on the circuit board 40. In this embodiment, the airflow sensing device 50 can be an airflow sensor or a microphone. Specifically, the airflow sensor can be a MEMS airflow sensor, and the MEMS airflow sensor is welded to the circuit board 40.

[0065] As Figures 3 to 9 shown, further, in this embodiment, the power supply assembly further includes a conductive structure, which can be disposed on the bracket 20. Specifically, it can be disposed on the bottom wall 21 of the bracket 20 and integrally formed with the bottom wall 21. Of course, it can be understood that the conductive structure is not limited to being disposed on the bottom wall 21 of the bracket 20, and can also be disposed on the side wall 22 and the first end wall 23 of the bracket 20. The conductive structure can connect the circuit board 40 and the battery cell 30 and charge the battery cell 30, or only be used to connect the circuit board 40 and the battery cell 30, or only charge the battery cell 30. The conductive structure can form an integral structure with the bracket 20. In this embodiment, the conductive structure and the bracket 20 can be integrally formed by injection molding.

Specifically, the battery cell conductive member 60 and the bracket 20 can be integrally formed by injection molding, so that there is no need to additionally provide an insulating member to wrap the battery cell conductive member 60, thereby improving the assembly efficiency and safety reliability and facilitating automated production. In this embodiment, the battery cell conductive member 60 can penetrate through the bottom wall 21 and be disposed between the first receiving cavity 201 and the second receiving cavity 202. Specifically, the battery cell conductive member 60 can penetrate through the boss 26 and the blocking wall 25 and respectively abut against the circuit board 40 and the battery cell 30, so as to conductively connect the circuit board 40 and the battery cell 30. By adopting a contact method, welding and parts can be reduced, and thus automated production can be facilitated.

[0067] In this embodiment, the cell conductive member 60 can be a metal elastic sheet. Specifically, the material of the metal elastic sheet is preferably stainless steel or phosphor bronze. Of course, it can be understood that in some other embodiments, the material of the cell conductive member 60 is not limited to the materials listed above.

The first conductive contact portion 61 passes through the boss 26 on the bottom wall 21 and can be used to contact the cell 30.

In this embodiment, one end of the second deformation portion 64 can be bent to form the second conductive contact portion 62. The second conductive contact portion 62 can pass through the retaining wall 25 and can be used to contact the circuit board 40. In this embodiment, the conductive layer can be provided on the first conductive contact portion 61 and the second conductive contact portion 62.

[0071] The first deformation portion 63 can be provided at one end of the first conductive contact portion 61 close to the connecting portion 67. The second deformation portion 64 can be provided at one end of the second conductive contact portion 62 close to the connecting portion 67. The first deformation portion 63 and the second deformation portion 64 can be arranged in a V shape. By providing the first deformation portion 63 and the second deformation portion 64, the entire cell conductive member 60 can have an elastic deformation space, and further, the first conductive contact portion 61 and the second conductive contact portion 62 of the cell conductive member 60 can form better contacts with the corresponding positions of the cell 30 and the circuit board 40 respectively.

[0072] The first support portion 65 and the second support portion 66 can be arranged side by side and parallel at both ends of the connecting portion 67. One end of the first support portion 65 can be connected to the first deformation portion 63, and the other end can be connected to the connecting portion 67. The first support portion 65 and the connecting portion 67 can be bent to form a third set angle. In this embodiment, the third set angle can be a right angle. Of course, it can be understood that in some other embodiments, the third set angle may not be limited to a right angle. The first support portion 65 and the first deformation portion 63 can be bent to form a fourth set angle, and the fourth set angle can be an obtuse angle. It can be understood that in some other embodiments, the fourth set angle may not be limited to an obtuse angle.

[0073] In this embodiment, one end of the second support portion 66 can be connected to the second deformation portion 64, and the other end can be connected to the connecting portion 67. The second support portion 66 and the connecting portion 67 can be bent to form a fifth set angle. In this embodiment, the fifth set angle can be a right angle. Of course, it can be understood that in some other embodiments, the fifth set angle may not be limited to a right angle. In this embodiment, the second support portion 66, the connecting portion 67 and the second deformation portion 64 can be bent to form a sixth set angle, and the sixth set angle can be an obtuse angle. It can be understood that in some other embodiments, the sixth set angle may not be limited to an obtuse angle.

[0074] In this embodiment, the connecting portion 67 can be integrally formed with the bracket 20. Specifically, in this embodiment, the connecting portion 67 can pass through the retaining wall 25 and the boss 26, and form an integral structure with the retaining wall 25 and the boss 26 by injection molding. Both ends of the connecting portion 67 can be respectively connected to the first support portion 65 and the second support portion 66, and further connect the first conductive contact portion 61 and the second conductive contact portion 62.

[0075] Furthermore, in this embodiment, there can be multiple cell conductive members 60. Two opposite sides of the cell conductive members 60 can respectively extend towards the circuit board 40 and the cell 30, and can be respectively abutted against the circuit board 40 and the cell 30. In this embodiment, the orientations of the multiple cell conductive members 60 are consistent. Specifically, the orientations of the first conductive contact portions 61 of the multiple cell conductive members 60 are the same, and the orientations of the second conductive contact portions 62 of the multiple cell conductive members 60 are the same. The first conductive contact portions 61 of the multiple cell conductive members 60 all extend towards the first accommodation cavity 201, and the second conductive contact portions 62 of the multiple cell conductive members 60 all extend towards the second accommodation cavity 202. By keeping the orientations of the cell conductive members 60 consistent, it is convenient for the installation of the circuit board 40 and the cell 30, and further facilitates the realization of automatic assembly.

Specifically, in this embodiment, the charging conductive member 70 can be integrally formed with the bracket 20 by injection molding, so that there is no need to additionally set an insulating member to wrap the charging conductive member 70, which can not only save the welding process, but also improve the assembly efficiency and safety of the power supply component. The charging conductive member 70 can be partially buried in the bottom wall 21 and the first end wall 23, and can extend from the first accommodating cavity 201 to the second accommodating cavity 202 to abut against the circuit board 40.

[0094] In this embodiment, the charging conductive member 70 can further include second positioning holes 7141, 7251. There are two second positioning holes 7141, 7251, and the two second positioning holes 7141, 7251 are respectively disposed on the first connecting arm 714 and the second connecting arm 725. Through the second positioning holes 7141, 7251, it is convenient to position the charging conductive member in the mold during injection molding.

[0095] Such as Figure 5 、 Figure 11 、and Figure 12As shown, further, in this embodiment, the power supply assembly may further include a first seal 80, which can cooperate with the bracket 20 and is correspondingly arranged with the airflow sensing device 50. Specifically, in this embodiment, the first seal 80 may be disposed at the opening of the second accommodation cavity 202 of the bracket 20 and press-fitted onto the circuit board 40. In this embodiment, the first seal 80 may be a silicone part. Of course, it can be understood that in some other embodiments, the first seal 80 may not be limited to a silicone part. 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 accommodation cavity 202.

[0096] Furthermore, in the present embodiment, the first seal 80 includes an elastic body 81, and the shape and size of the elastic body 81 can be adapted to the second accommodation cavity 202. In the present embodiment, a first opening 82, a second opening 83, and a fluid passage 84 connecting the first opening 82 and the second opening 83 may be provided on the first seal 80. The first opening 82 may be located on the elastic body 81 and near the second end wall 24, and is communicated with the air inlet hole 241 on the second end wall 24. The first opening 82 allows air flow to flow out and into the air inlet hole 241 of the second end wall 24, and if there is condensate, it can allow the condensate to flow in. The second opening 83 may be provided on the elastic body 81 and near the retaining wall 25. The second opening 83 may be communicated with the air flow hole 401 on the circuit board 40, and then communicated with the air flow sensing device 50. In the present embodiment, the cross-sectional area of the second opening 83 may be larger than the cross-sectional area of the air flow hole 401 on the circuit board 40, so that even when there is a slight misalignment during installation, it does not affect the normal operation of the air flow sensing device 50. Specifically, the second opening 83 and the air flow 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 air flow hole 401 of the circuit board 40. The fluid passage 84 may connect the first opening 82 and the second opening 83. When the user sucks, the gas can pass through the air flow sensing device 50 and enter the second opening from the air flow hole 401 of the circuit board 40, and then output to the air inlet hole 241 of the second end wall 24 through the fluid passage, so that the air flow sensing device 50 is in a negative pressure state. The condensate can be output from the air inlet hole 241 and enter the first opening 82 and then into the fluid passage 84, and can be stored in the fluid passage 84. In the present embodiment, the fluid passage can be designed such that the path for the condensate to flow from the first opening 82 through the fluid passage 84 into the second opening 83 is longer than the path for the air flow to flow out from the second opening 83 through the fluid passage 84 to the first opening 82, that is, the fluid passage has different flow resistances for different flow directions, so that the air flow can flow normally to the first opening 82 to achieve the normal operation of the air flow sensing device 50, while the condensate is difficult to flow to the second opening 83, thereby avoiding the condensate from corroding the air flow sensing device 50 and the circuit board 40.

[0097] Further, in the present embodiment, the fluid passage 84 includes a main passage 841 and at least one return passage 842. The main passage 841 can be centrally arranged and can be linearly distributed, with one end communicating with the first opening 82 and the other end communicating with the second opening 83. Of course, it can be understood that in some other embodiments, the main passage 841 is not limited to being centrally arranged and is not limited to being linearly distributed. There can be multiple return passages 842, and multiple return passages 842 can be arranged side by side on both opposite sides of the main passage 841. Of course, it can be understood that in some other embodiments, there can also be only one return passage 842. The return passage 842 can communicate with the main passage 841, increasing the fluid path, thereby reducing the condensate from flowing back to the circuit board 40 and preventing the condensate from contaminating the circuit board 40 and the airflow sensing device 50. In the present embodiment, the return passage 842 can be inclined towards the second opening 83 and can form a set angle with the main passage 841. In the present embodiment, the set angle can be an acute angle. Specifically, the set angle can be 30 to 60 degrees, preferably 45 degrees. By inclining the return passage 842 at an acute angle with respect to the longitudinal axis of the main passage 841, the structural space can be optimized.

[0098] Further, in the present embodiment, the return passage 842 includes a flow portion 8421, a return portion 8422, and a connection portion 8423. The flow portion 8421 can communicate with the main passage 841, and the condensate can flow from the main passage 841 into the flow portion 8421. The return portion 8422 can communicate with the main passage 841 and the flow portion 8421, and the return portion 8422 and the flow portion 8421 can be linearly arranged, and the flow portion 8421 and the return portion 8422 can be parallel to each other. Of course, it can be understood that in some other embodiments, the return portion 8422 and the flow portion 8421 are not limited to being linearly arranged and can also be curved. In some other embodiments, the flow portion 8421 and the return portion 8422 are not limited to being parallel to each other and can also be distributed in a V-shaped pattern. The connection portion 8423 can be used to connect the flow portion 8421 and the return portion 8422. The condensate can flow from the flow portion 8421, then through the connection portion 8423 to the return portion 8422, and return from the return portion 8422 to the main passage 841.

[0099] Further, in the present embodiment, through holes 85 can be provided on the first seal 80. There can be four through holes 85, which can be distributed at the four corners of the elastic body 81. The through holes 85 can penetrate the elastic body 81 along the thickness direction of the elastic body 81 and can be used for screws to pass through, so as to facilitate the connection and fixation of the first seal 80 and the bracket 20 by screws. In the present embodiment, the through holes 85 can also be used for ventilation.

[0100] Further, in the present embodiment, a pressure relief groove 86 is provided on the first seal 80, and the pressure relief groove 86 can communicate with the fluid passage 84. Specifically, in the present embodiment, the pressure relief groove 86 is disposed adjacent to the second opening 83, one end of which can communicate with the fluid passage 84, and the other end can communicate with one of the through holes 85. The function of the pressure relief groove 86 is that when the user does not suck, the airflow sensing device 50 needs to stop working. However, due to the large flow resistance of the fluid passage 84 flowing from the first opening 82 to the second opening 83, it is difficult for the airflow to flow back to the airflow sensing device 50. At this time, the pressure relief groove 86 can supplement the air pressure to relieve the negative pressure state of the airflow sensing device 50 so as to ensure the normal operation of the airflow sensing device 50.

[0101] Further, in the present embodiment, a positioning protrusion 87 can be provided on the first seal 80. The positioning protrusion 87 can be disposed on the side of the elastic body 81 opposite to the airflow sensing device 50 and can cooperate with the airflow sensing device 50 for positioning. In the present embodiment, when the first seal 80 is pressed against the circuit board 40, the positioning protrusion 87 can be pressed on the air hole 401 on the circuit board 40. In the present embodiment, the second opening 83 can be formed in the positioning protrusion 87. In the present embodiment, a sealing rib 871 can be provided on the protruding end surface of the positioning protrusion 87. The sealing rib 871 can protrude toward the circuit board 40 and can be used to seal the gap between the second opening 83 and the circuit board 40.

[0102] Further, in the present embodiment, a sealing ring 88 for cooperating with the second seal 90 can be provided on the first seal 80. The sealing ring 88 can be provided on the elastic body 81 and can be disposed along the circumferential direction of the elastic body 81.

[0103] Further, in the present embodiment, a light guide column can also be provided on the first seal 80. The light guide column can protrude from the elastic body 81 and can be correspondingly disposed with the LED lamp on the circuit board 40.

[0104] As Figure 5 and Figure 13As shown, further, in this embodiment, the power supply assembly may also include a second seal 90, which may cooperate with the bracket 20. 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. The inner side of the first crimping structure 92 is a hollow structure, and a through hole 920 for a screw to pass through may be formed. 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 battery cell 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 arranged at intervals.

[0105] 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 .

[0106] Further, in this embodiment, the power supply assembly may further include electrode members 110. There may be two electrode members 110, which may be spaced apart and respectively penetrate through the sealing cover 100 and the second end wall 24, and may be used to connect the circuit board 40 and the atomizer. In this embodiment, the electrode member 110 includes an elastic abutting portion 111, a clamping portion 112, a receiving portion 113, and a conductive connecting portion 114. The elastic abutting portion 111 may penetrate out of the second end wall 24 of the bracket 20 and may abut against the atomizer. Specifically, it may elastically abut against the electrode post of the atomizer. The clamping portion 112 may be disposed on the outer peripheral wall of the elastic abutting portion 111. The clamping portion 112 may be annular and may be located at one end of the elastic abutting portion 111. The clamping portion 112 may be clamped on the electrode hole of the second end wall 24. The receiving portion 113 may be columnar and may be disposed on a side of the clamping portion 112 opposite to the elastic abutting portion 111. The receiving portion 113 may be received in the electrode hole of the second end wall 24. The conductive connecting portion 114 may penetrate into the second receiving cavity 202 of the bracket 20 from the second end wall 24 and may be connected to the circuit board 40. Specifically, the conductive connecting portion 114 may be welded to the pad of the circuit board 40 by a spot welder. In this embodiment, the height of the conductive connecting portion 114 may be 0.1 mm - 0.3 mm, preferably 0.2 mm. The area of the pad is larger than the cross-sectional area of the conductive connecting portion 114. Preferably, the pad is rectangularly arranged, and the projection of the conductive connecting portion 114 falls within the interval defined by the pad.

[0107] As Figure 14 shown, in this embodiment, the method for preparing the bracket may include the following steps:

[0108] S1. Provide a rear mold and a front mold that cooperates with the rear mold to form a cavity. Place the prefabricated conductive member with an integral structure in the rear mold, and place the front mold on the rear mold to press against the prefabricated conductive member.

A plurality of first convex parts extending downward can be arranged on the inner side of the top wall of the front mold. The plurality of first convex parts can be arranged near the middle of the top wall of the front mold, and can be arranged side by side and at intervals.

Specifically, in some embodiments, the plurality of battery cell conductive parts 60, the first charging conductive unit 71 and the second charging conductive unit 72 can be formed into a strip-shaped integral structure by casting.

[0111] In this step, the prefabricated conductive part can be placed in the rear mold, and the second positioning holes 7141, 7251 on the prefabricated conductive part are matched with the positioning posts protruding from the inner side of the top wall of the front mold for positioning, so as to position the entire prefabricated conductive part in the rear mold.

[0112] S2. Inject plastic into the rear mold, and form a bracket 20 that is an integral structure with the prefabricated conductive part and has a punching hole left after curing; as Figure 6As shown, in this step, the plastic can be filled in the gaps between the convex portions.
