[0059] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0060] Figure 1 Some preferred embodiments of the electronic atomizing device of the present invention are shown. In this embodiment, the electronic atomizing device includes an atomizer A and a power supply component B; the atomizer A can be used to heat the atomizing medium, such as e-liquid. The power supply component B can be mechanically and / or electrically connected to the atomizer A and can provide electrical energy to the atomizer A.

[0061] like Figures 2 to 4 As shown, 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 houses the bracket 20, the battery cell 30, and the circuit board 40. The bracket 20 is disposed within the housing 10 and supports the battery cell 30 and the circuit board 40. The battery cell 30 is disposed on the bracket 20, located at the lower part of the bracket 20, and provides electrical energy to the atomizer. The circuit board 40 is disposed on the bracket 20 and is electrically connected to the battery cell 30.

[0062] Furthermore, in this embodiment, the outer casing 10 is a cylindrical structure with an opening at one end. The outer casing 10 can be an injection-molded part; of course, it is understood that in some other embodiments, the outer casing 10 can also be a metal casing. In this embodiment, a pressure relief hole 101 can be provided on the outer casing 10. This pressure relief hole 101 can release the gas pressure in the outer casing 10 when an explosion occurs at the battery cell end, thereby preventing further pressure escalation and reducing the intensity of the explosion.

[0063] like Figures 6 to 7As shown, further, in this embodiment, the bracket 20 is an insulating component; specifically, the bracket 20 can be an injection-molded component, and more specifically, the bracket 20 can be made of plastic. Of course, it is understood that in other embodiments, the bracket 20 is not limited to plastic 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. The second end wall 24 can be provided with an air inlet 241 communicating with the atomizer to allow gas to enter the atomizer. The first end wall 23 can be arranged parallel to the second end wall 24. The bottom wall 21, side wall 22, first end wall 23 and second end wall 24 can be arranged to form a receiving space with an opening that can accommodate the battery cell 30 and the circuit board 40.

[0064] Furthermore, in this embodiment, the support 20 may also include a baffle 25, which is disposed in the receiving space along a direction transverse to the bottom wall 21, dividing the receiving space into a first receiving cavity 201 and a second receiving cavity 202. The first receiving cavity 201 can be used to receive the battery cell 30, and the second receiving cavity 202 can be used to receive the circuit board 40. In this embodiment, the first receiving cavity 201 and the second receiving cavity 202 can be disposed independently, and the first receiving cavity 201 and the second receiving cavity 202 can be isolated from each other, thereby preventing the electrolyte of the battery cell 30 from corroding the circuit board 40, and thus improving the sensitivity of the airflow sensing device 50. In this embodiment, both the first receiving cavity 201 and the second receiving cavity 202 can be cuboid in shape, and the second receiving cavity 202 can be disposed side by side with the first receiving cavity 201, and the second receiving cavity 202 can be disposed near the end of the support 20 that contacts the atomizer A. The size of the second accommodating cavity 202 can be smaller than the size of the first accommodating cavity 201. Specifically, the length of the second accommodating cavity 202 is smaller than the length of the first accommodating cavity 201, thereby better preventing the electrolyte of the battery cell 30 from corroding the circuit board 40, and shortening the length of the sensing air passage of the airflow sensing device 50, thereby improving the sensitivity of the airflow sensing device 50.

[0065] 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 may be used to receive the 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 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 is understood that in some other embodiments, the size of the receiving groove 203 may be comparable to the size of the battery cell circuit board 32.

[0066] In this embodiment, the bracket 20 may also be provided with a boss 26. The boss 26 may be disposed close to the baffle 25 and located in the receiving groove 203, and may protrude from the bottom wall 21. It may be used to support the conductive component 60 of the battery cell and limit the pressing force of the battery cell circuit board 32 on the conductive component 60 of the battery cell 30. The shape of the boss 26 may be adapted to the shape of the battery cell circuit board 32. The boss 26 may be cuboid in shape. Of course, it is understood that in some other embodiments, the boss 26 may not be limited to being cuboid in shape. 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.

[0067] In this embodiment, limiting notches 27 can be provided on two opposite sides of the receiving groove 203. There can be two limiting notches 27, which can be formed on the sidewalls 22 at both ends of the boss 26. The limiting notches 27 can be used to limit the position of the battery cell circuit board 32, and can also facilitate the receiving groove 203 to accommodate battery cell circuit boards 32 with a longer length, thereby increasing the applicability of the receiving groove 203.

[0068] 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 may also be used to limit the pressing force of the battery cell circuit board 32 on the battery cell conductive element 60. It is understood that in other embodiments, the steps 28 may be omitted.

[0069] In this embodiment, a pressure relief port 221 may be provided on the side wall 22 corresponding to the first accommodating cavity 201. The pressure relief port 221 may communicate with the pressure relief hole 101 on the outer casing 10. When an explosion occurs at the battery cell end, the gas pressure can be released from the pressure relief port 221 through the pressure relief hole, thereby preventing further pressure rise and reducing the intensity of the explosion. In this embodiment, the pressure relief port 221 may be rectangular. Of course, it is understood that in some other embodiments, the pressure relief port 221 may not be limited to being rectangular.

[0070] 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 its size is smaller than the size of the pressure relief port 221. In this embodiment, the thin wall 222 may be rectangular, and its 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 it and the side walls on both sides of the pressure relief port 221 to allow the gas pressure in the first accommodating cavity 201 to be discharged. The thin wall 222 allows the pressure relief port 221 to be staggered from the pressure relief hole 101 on the outer casing 10, and ensures that the battery cell 30 is partially exposed, avoiding short circuits in the battery cell 30. The outer wall surface of the thin wall 222 may form a gas storage cavity with the outer casing 10 of the power supply component A, thereby storing gas. The gas storage cavity may communicate with the pressure relief hole 101 on the outer casing 10. The gas storage chamber increases the gas passage area and gas volume, thereby enabling rapid and effective pressure release. This prevents further pressure build-up in the first accommodating chamber 201 and reduces the intensity of the explosion.

[0071] In this embodiment, a pressure relief through-hole 215, communicating with the second accommodating cavity 202, can be provided on the bottom wall 21 corresponding to the second accommodating cavity 202 for pressure relief. This pressure relief through-hole 215 can be located 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 it detects a change in air pressure. The presence of the pressure relief through-hole 215 allows the space where the airflow sensing device 50 is located to communicate with the outside world, activating it through changes in negative pressure and atmospheric pressure during suction, resulting in higher activation accuracy. If the space inside is sealed, the amplitude of the diaphragm in the airflow sensing device 50 may not be large enough, leading to insensitive activation.

[0072] like Figure 5 As shown, further, in this embodiment, the battery cell 30 is housed in the first accommodating cavity 201. The battery cell 30 is a rechargeable battery and can be powered by an external power source, thereby continuously providing power to the atomizer, improving the cycle life of the power supply component and reducing resource waste. In this embodiment, the battery cell 30 may include a battery cell body 31 and a battery cell circuit board 32. The battery cell circuit board 32 may be disposed at one end of the battery cell body 31 and may be connected to the battery cell body 31 by means of a lead wire 33. The battery cell body 31 may be housed in the first accommodating cavity 201, and the battery cell circuit board 32 may be housed in an accommodating groove 203 located at one end of the first accommodating cavity 201, with both ends being snapped onto the limiting notch 27. The battery cell circuit board 32 may be electrically connected to the circuit board 40 through the battery cell conductive element 60.

[0073] Furthermore, in this embodiment, the circuit board 40 is housed within the second accommodating cavity 202. The power supply assembly 20 also includes an airflow sensing device 50, which can be disposed within the second accommodating cavity 202 and electrically connected to the circuit board 40. An airflow hole 401 for airflow 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, which is soldered onto the circuit board 40.

[0074] like Figures 3 to 9 As shown, further in this embodiment, the power supply component also includes a conductive structure. This conductive structure can be disposed on the bracket 20, specifically on the bottom wall 21 of the bracket 20 and integrally formed with the bottom wall 21. Of course, it is understood that the conductive structure is not limited to being disposed on the bottom wall 21 of the bracket 20, but can also be disposed on the side wall 22 and the first end wall 23 of the bracket 20. This conductive structure can connect the circuit board 40 and the battery cell 30, and charge the battery cell 30, or it can only be used to connect the circuit board 40 and the battery cell 30, or only to charge the battery cell 30. The conductive structure can form an integral structure with the bracket 20. In this embodiment, the conductive structure can be integrally formed with the bracket 20 by injection molding. In this embodiment, the conductive structure can be a sheet structure, specifically a metal spring. A conductive layer can be disposed on the contact surface between the conductive structure and the circuit board 40 and the battery cell 30, or on the contact surface between the conductive structure and the circuit board 40 and the external power supply. The conductive layer can be a metal coating. In this embodiment, the material of the conductive layer can be gold. The conductive layer can increase the conductivity between the conductive structure and the circuit board 40 and the battery cell 30, or increase the conductivity between the circuit board 40 and the external power supply.

[0075] In this embodiment, the conductive structure may include a battery cell conductive element 60, which is disposed on the bracket 20 and can form an integral structure with the bracket 20. It can also abut against the circuit board 40 and the battery cell 30, thereby electrically connecting the circuit board 40 and the battery cell 30. Specifically, the battery cell conductive element 60 can be integrally formed with the bracket 20 through injection molding, thus eliminating the need for additional insulating components to enclose the battery cell conductive element 60, thereby improving assembly efficiency and safety reliability, and facilitating automated production. In this embodiment, the battery cell conductive element 60 can pass through the bottom wall 21 and is disposed between the first accommodating cavity 201 and the second accommodating cavity 202. Specifically, the battery cell conductive element 60 can pass through the boss 26 and the baffle 25, and can abut against the circuit board 40 and the battery cell 30 respectively, thereby electrically connecting the circuit board 40 and the battery cell 30. Using a contact method reduces welding and parts, thus facilitating automated production.

[0076] In this embodiment, the conductive element 60 of the battery cell can be a metal spring. Specifically, the metal spring is preferably made of stainless steel or phosphor bronze. Of course, it is understood that in other embodiments, the material of the conductive element 60 is not limited to the materials listed above. In this embodiment, a conductive layer can be provided on the contact surface between the conductive element 60 and the circuit board 40 and the battery cell 30. The material of the conductive layer can be gold, and the conductive layer can be formed by plating gold on the contact surface between the conductive element 60 and the circuit board 40 and the battery cell 30.

[0077] Furthermore, in this embodiment, the conductive component 60 of the battery cell includes a first conductive contact portion 61, a second conductive contact portion 62, a first deformable portion 63, a second deformable portion 64, a first support portion 65, a second support portion 66, and a connecting portion 67.

[0078] The first conductive contact 61 is disposed at one end of the first deformable portion 63 and can be bent to form a first predetermined angle with the first deformable portion 63. In this embodiment, the first predetermined angle can be an acute angle. Of course, it is understood that in some other embodiments, the first predetermined angle is not limited to an acute angle. In this embodiment, one end of the first deformable portion 63 can be bent to form the first conductive contact 61. The first conductive contact 61 protrudes from the protrusion 26 on the bottom wall 21 and can be used to contact the battery cell 30.

[0079] In this embodiment, the second conductive contact 62 is disposed opposite to the first conductive contact 61. The second conductive contact 62 is located at one end of the second deformable portion 64 and can be bent to form a second predetermined angle with the second deformable portion 64. In this embodiment, the second predetermined angle can be an acute angle. Of course, it is understood that in some other embodiments, the second predetermined angle is not limited to an acute angle. In this embodiment, one end of the second deformable portion 64 can be bent to form the second conductive contact 62. The second conductive contact 62 can protrude from the baffle 25 and can be used to contact the circuit board 40. In this embodiment, the conductive layer can be disposed on the first conductive contact 61 and the second conductive contact 62.

[0080] The first deformable portion 63 can be disposed at one end of the first conductive contact portion 61 near the connecting portion 67, and the second deformable portion 64 can be disposed at one end of the second conductive contact portion 62 near the connecting portion 67. The first deformable portion 63 and the second deformable portion 64 can be arranged in a V-shape. By providing the first deformable portion 63 and the second deformable portion 64, the entire battery cell conductive component 60 can have elastic deformation space, thereby enabling the first conductive contact portion 61 and the second conductive contact portion 62 of the battery cell conductive component 60 to form better contact with the corresponding positions of the battery cell 30 and the circuit board 40, respectively.

[0081] 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 deformable 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 predetermined angle. In this embodiment, the third predetermined angle can be a right angle. Of course, it is understood that in some other embodiments, the third predetermined angle is not limited to a right angle. The first support portion 65 and the first deformable portion 63 can be bent to form a fourth predetermined angle. The fourth predetermined angle can be an obtuse angle. It is understood that in some other embodiments, the fourth predetermined angle is not limited to an obtuse angle.

[0082] In this embodiment, one end of the second support portion 66 can be connected to the second deformable 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 predetermined angle. In this embodiment, the fifth predetermined angle can be a right angle. Of course, it is understood that in some other embodiments, the fifth predetermined angle is not limited to a right angle. In this embodiment, the second support portion 66, the connecting portion 67, and the second deformable portion 64 can be bent to form a sixth predetermined angle. The sixth predetermined angle can be an obtuse angle. It is understood that in some other embodiments, the sixth predetermined angle is not limited to an obtuse angle.

[0083] 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 baffle 25 and the boss 26, and form an integral structure with the baffle 25 and the boss 26 through injection molding. The two ends of the connecting portion 67 can be connected to the first support portion 65 and the second support portion 66 respectively, thereby connecting the first conductive contact portion 61 and the second conductive contact portion 62.

[0084] Furthermore, in this embodiment, there can be multiple conductive elements 60. The two opposite sides of each conductive element 60 can extend towards the circuit board 40 and the battery cell 30 respectively, thereby abutting against the circuit board 40 and the battery cell 30 respectively. In this embodiment, the orientation of the multiple conductive elements 60 is consistent. Specifically, the first conductive contact portions 61 of the multiple conductive elements 60 have the same orientation, and the second conductive contact portions 62 of the multiple conductive elements 60 have the same orientation. The first conductive contact portions 61 of the multiple conductive elements 60 all extend towards the first accommodating cavity 201, and the second conductive contact portions 62 of the multiple conductive elements 60 all extend towards the second accommodating cavity 202. By maintaining a consistent orientation of the conductive elements 60, the installation of the circuit board 40 and the battery cell 30 can be facilitated, thereby facilitating automated assembly.

[0085] In this embodiment, there can be three conductive elements 60 in the battery cell. However, it is understood that in other embodiments, the number of conductive elements 60 may not be limited to three. In this embodiment, the conductive elements 60 include a first conductive element 60a, a second conductive element 60b, and a third conductive element 60c. These three conductive elements are arranged side-by-side. The first conductive element 60a connects the positive terminal of the battery cell 30 to the circuit board 40. The second conductive element 60b connects the negative terminal of the battery cell 30 to the circuit board 40. The third conductive element 60c transmits control signals from the circuit board 40 to the battery cell 30. The first conductive element 60a, the second conductive element 60b, and the third conductive element 60c of the battery cell have the same orientation. Specifically, the first conductive contact portion 61 of the first conductive element 60a, the second conductive element 60b, and the third conductive element 60c have the same orientation, as do their second conductive contact portions 62.

[0086] like Figure 5 , Figure 6 , Figure 8 and Figure 10 As shown, further in this embodiment, the conductive structure also includes a charging conductive element 70, which can be disposed on the bracket 20 and can form an integral structure with the bracket 20. Specifically, in this embodiment, the charging conductive element 70 can be integrally formed with the bracket 20 by injection molding, thereby eliminating the need for additional insulating parts to wrap the charging conductive element 70. This not only saves the welding process but also improves the assembly efficiency and safety of the power supply component. The charging conductive element 70 can be partially embedded 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. The charging conductive element 70 can be connected to the external power supply, which can conductively connect the external power supply to the circuit board 40, thereby facilitating the charging of the battery cell 30 by the external power supply.

[0087] In this embodiment, the charging conductive element 70 can be a metal spring. Specifically, the metal spring is preferably made of stainless steel or phosphor bronze.

[0103] In this embodiment, the charging conductive component 70 may further include second positioning holes 7141 and 7251. There are two second positioning holes 7141 and 7251, respectively disposed on the first connecting arm 714 and the second connecting arm 725. The second positioning holes 7141 and 7251 facilitate the positioning of the charging conductive component in the mold during injection molding.

[0104] like Figure 5 , Figure 11 ,and Figure 12As shown, further in this embodiment, the power supply component may also include a first sealing member 80, which can cooperate with the bracket 20 and can be correspondingly disposed with the airflow sensing device 50. Specifically, in this embodiment, the first sealing member 80 can be disposed at the opening of the second accommodating cavity 202 of the bracket 20 and pressed onto the circuit board 40. In this embodiment, the first sealing member 80 can be a silicone component; of course, it is understood that in some other embodiments, the first sealing member 80 is not limited to a silicone component. In this embodiment, the longitudinal section of the first sealing member 80 can be square, and its shape and size can be adapted to the second accommodating cavity 202.

[0105] Further, in this embodiment, the first sealing member 80 includes an elastic body 81, the shape and size of which are adapted to the second accommodating cavity 202. In this embodiment, the first sealing member 80 may 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 may be located on the elastic body 81 and near the second end wall 24, and communicate with the air inlet 241 on the second end wall 24. The first opening 82 allows airflow to flow out and into the air inlet 241 of the second end wall 24, and allows condensate to flow in if present. The second opening 83 may be provided on the elastic body 81 and near the baffle 25. The second opening 83 may communicate with the airflow hole 401 on the circuit board 40, and thus with the airflow sensing device 50. In this embodiment, the cross-sectional area of ​​the second opening 83 can be larger than the cross-sectional area of ​​the airflow hole 401 on the circuit board 40, so that even if slight misalignment occurs during installation, it will not affect the normal operation of the airflow sensing device 50. Specifically, the second opening 83 and the airflow hole 401 of the circuit board 40 can be circular holes, and the diameter of the second opening 83 can be larger than the diameter of the airflow hole 401 of the circuit board 40. The fluid channel 84 can connect the first opening 82 and the second opening 83. When the user draws air, the gas can 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 and exit from the second opening 83 to the air inlet 241 of the second end wall 24, thereby putting the airflow sensing device 50 in a negative pressure state. The condensate can be output from the air inlet 241 into the first opening 82 and into the fluid channel 84, and can be stored in the fluid channel 84. In this embodiment, the fluid channel can be designed such that the path of condensate flowing from the first opening 82 through the fluid channel 84 into the second opening 83 is longer than the path of 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 resistance for different flow directions, so that the airflow can flow normally to the first opening 82 to realize the normal operation of the airflow sensing device 50, while the condensate is difficult to flow to the second opening 83, thereby avoiding corrosion of the airflow sensing device 50 and the circuit board 40 by the condensate.

[0106] Further, in this embodiment, the fluid channel 84 includes a main channel 841 and at least one return channel 842. The main channel 841 may be centrally located and may be linearly distributed, with one end connected to the first opening 82 and the other end connected to the second opening 83. Of course, it is understood that in some other embodiments, the main channel 841 is not limited to being centrally located, nor is it limited to being linearly distributed. There may be multiple return channels 842, and multiple return channels 842 may be arranged side by side on both opposite sides of the main channel 841. Of course, it is understood that in some other embodiments, there may also be only one return channel 842. The return channel 842 may be connected to the main channel 841, which can increase the fluid path, thereby reducing the backflow of condensate to the circuit board 40 and preventing condensate from contaminating the circuit board 40 and the airflow sensing device 50. In this embodiment, the return channel 842 can be inclined 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 inclining the return channel 842 at an acute angle relative to the longitudinal axis of the main channel 841, the structural space can be optimized.

[0107] Further, in this embodiment, the return channel 842 includes a flow section 8421, a return section 8422, and a connecting section 8423. The flow section 8421 can communicate with the main channel 841, and condensate can flow into the flow section 8421 from the main channel 841. The return section 8422 can communicate with both the main channel 841 and the flow section 8421, and the return section 8422 and the flow section 8421 can be arranged in a straight line, and the flow section 8421 and the return section 8422 can be arranged parallel to each other. Of course, it is understood that in some other embodiments, the return section 8422 and the flow section 8421 are not limited to being arranged in a straight line, but can also be arranged in a curve. In some other embodiments, the flow section 8421 and the return section 8422 are not limited to being arranged in parallel, but can also be arranged in a figure-eight shape. The connecting section 8423 can be used to connect the flow section 8421 and the return section 8422. The condensate can flow into the flow section 8421 and then through the connecting section 8423 to the return section 8422, and then return to the main channel 841 from the return section 8422.

[0108] Furthermore, in this embodiment, the first sealing member 80 may be provided with through holes 85, and there may be four through holes 85, which may be distributed at the four corners of the elastic body 81. The through holes 85 may be provided through the elastic body 81 along the thickness direction, and can 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 holes 85 can also be used for ventilation.

[0109] Furthermore, in this embodiment, the first sealing member 80 is provided with a pressure relief groove 86, which can communicate with the fluid channel 84. Specifically, in this embodiment, the pressure relief groove 86 can be located near the second opening 83, with one end communicating with the fluid channel 84 and the other end communicating with one of the through holes 85. The function of the pressure relief groove 86 is that when the user is not suctioning, the airflow sensing device 50 needs to stop working. However, due to the large flow resistance of the fluid channel 84 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 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.

[0110] Furthermore, in this embodiment, a positioning protrusion 87 may be provided on the first sealing member 80. The positioning protrusion 87 may be provided on the side of the elastic body 81 opposite to the airflow sensing device 50, and may cooperate with the airflow sensing device 50 for positioning. In this embodiment, when the first sealing member 80 is pressed onto the circuit board 40, the positioning protrusion 87 may be pressed onto the airflow hole 401 on the circuit board 40. In this embodiment, the second opening 83 may be formed in the positioning protrusion 87. In this embodiment, a sealing rib 871 may be provided on the protruding end face of the positioning protrusion 87. The sealing rib 871 may protrude toward the circuit board 40 and may be used to seal the gap between the second opening 83 and the circuit board 40.

[0111] Furthermore, in this embodiment, a sealing ring 88 that cooperates with the second sealing member 90 for sealing may be provided on the first sealing member 80. The sealing ring 88 may be provided on the elastic body 81 and may be provided along the circumference of the elastic body 81.

[0112] Furthermore, in this embodiment, a light guide post may also be provided on the first sealing member 80. The light guide post may protrude from the elastic body 81 and may be configured to correspond with the LED lights on the circuit board 40.

[0113] like Figure 5 and Figure 13As shown, further in this embodiment, the power supply component may also include a second sealing member 90, which can cooperate with the bracket 20. Specifically, the second sealing member 90 can be disposed in the second accommodating cavity 202 and pressed onto the first sealing member 80. It can be connected and fixed to the bracket 20 by screws. By sequentially disposing the first sealing member 80 and the second sealing member 90 from the inside to the outside in the second accommodating cavity 202, the second accommodating cavity 202 can be sealed to form a closed space, and the electrolyte leakage of the battery cell in the first accommodating cavity 201 can be avoided from contaminating the circuit board 40 and the airflow sensing device 50 in the second accommodating cavity 202. In this embodiment, the second sealing member 90 includes a body 91, a first pressing structure 92 disposed on one side of the body 91 and protruding toward the second accommodating cavity 202, and a second pressing structure 93 disposed on one side of the body 91 and protruding toward the boss 26. The first pressing structure 92 may be columnar, and there may be four of them, which may be spaced apart at the four corners of the body 91. Of course, it is understood that in some other embodiments, the first pressing structure 92 may not be limited to four. The four first pressing structures 92 may be provided one-to-one with the through holes 85 on the first sealing member 80, and may be pressed onto the circuit board 40 through the through holes 85. The inner side of the first pressing structure 92 is a hollow structure, which may form a through hole 920 for screws to pass through. In this embodiment, the first pressing structure 92 may include a columnar first pressing part 921 and a second pressing part 922, both of which may be pressed onto the circuit board 40. The second pressing part 922 may protrude from the outer wall of the first pressing part 921, thereby increasing the contact area between the first pressing structure 92 and the circuit board 40, so that the circuit board 40 can be stably pressed together. In this embodiment, the second crimping structure 93 is block-shaped and can be crimped onto the end of the circuit board 40 where it connects to the battery cell 30, thereby allowing the conductive sheet 60 and the circuit board 40 to make full contact. In this embodiment, there can be two second crimping structures 93, which can be spaced apart.

[0114] Furthermore, in this embodiment, the power supply component may also include a sealing cover 100, which may be a silicone part that can be fitted onto the top of the bracket 20 to seal the gap between the bracket 20 and the outer shell 10.

[0115] Furthermore, in this embodiment, the power supply assembly may also include electrode components 110. There may be two electrode components 110, spaced apart, and respectively passing through the sealing cover 100 and the second end wall 24, for connecting the circuit board 40 and the atomizer. In this embodiment, the electrode component 110 includes an elastic abutment portion 111, a locking portion 112, a receiving portion 113, and a conductive connection portion 114. The elastic abutment portion 111 can extend from the second end wall 24 of the bracket 20 and abut against the atomizer, specifically, it can elastically abut against the electrode post of the atomizer. The locking portion 112 can be disposed on the outer peripheral wall of the elastic abutment portion 111. The locking portion 112 can be annular and located at one end of the elastic abutment portion 111. The locking portion 112 can engage with the electrode hole of the second end wall 24. The receiving portion 113 may be columnar and may be disposed on the side of the engaging portion 112 opposite to the elastic abutment portion 111. The receiving portion 113 may be accommodated in the electrode hole of the second end wall 24. The conductive connection portion 114 may pass through the second end wall 24 into the second receiving cavity 202 of the bracket 20 and may be connected to the circuit board 40. Specifically, the conductive connection portion 114 may be soldered to the pad of the circuit board 40 by a spot welding machine. In this embodiment, the height of the conductive connection portion 114 may be 0.1mm-0.3mm, preferably 0.2mm, and the area of ​​the pad is larger than the cross-sectional area of ​​the conductive connection portion 114. Preferably, the pad is rectangular and the projection of the conductive connection portion 114 falls within the area defined by the pad.

[0117] S1. Provide a rear mold and a front mold that cooperates with the rear mold to form a cavity, place an integral prefabricated conductive component in the rear mold, and place the front mold on the rear mold to hold the prefabricated conductive component in place.

[0118] The rear mold can be hollow with an opening on one side. Multiple downward-extending first protrusions can be provided on the inner side of the top wall of the front mold. These first protrusions can be located near the center of the top wall of the front mold and can be arranged side-by-side with intervals.
