Description

Technical Field

[0001] This application relates to the field of aerosol generating devices, and in particular to a power supply component and an aerosol generating device. Background Technology

[0002] Common aerosol generating devices include an atomizer and a power supply assembly, with the atomizer connected to the power supply assembly. During operation, the power supply assembly supplies power to the atomizer. The power supply assembly typically contains conductive posts, which are directly soldered to a circuit board within the assembly. These conductive posts contact the atomizer, forming an electrical connection between the atomizer and the power supply assembly.

[0003] In some power supply components, the circuit board is parallel to the docking direction between the power supply component and the atomizer, and the conductive post needs to be designed as a bent structure. To ensure a firm solder joint, notches are made on the edge of the circuit board, and the conductive post is placed in the notch with both ends of the conductive post extending beyond the notch. This results in a relatively large overall dimension of the circuit board and conductive post in the thickness direction of the circuit board, making it prone to interference with other structures. Summary of the Invention

[0004] This application provides a power supply component and an aerosol generation device, which helps to reduce the overall size of the circuit board and conductive pillars in the thickness direction of the circuit board, and reduces the risk of interference with other structures. The technical solution is as follows: In a first aspect, embodiments of this application provide a power supply assembly, which includes a battery holder, a circuit board, and a battery. The battery holder includes a connecting portion, a first receiving portion, and a second receiving portion connected sequentially along a first direction.

The battery is electrically connected to the circuit board. A conductive block is connected to one side of the circuit board in a second direction. A conductive post is connected to the conductive block. The conductive post passes through the connecting portion along the first direction and is used to electrically connect to the atomizer. The second direction is perpendicular to the first direction.

[0005] For example, the circuit board is arranged perpendicular to the second direction.

[0006] In some examples, the circuit board has multiple conductive blocks, each of which is connected to a conductive post. The power supply assembly also includes an insulating cover that encloses the conductive blocks.

[0008] In some examples, the conductive block is located on the side of the circuit board facing the bottom of the circuit board receiving slot.

[0009] In some examples, the circuit board is provided with an airflow sensor on the side facing the bottom of the circuit board receiving groove, and the battery bracket is provided with a sensing air channel. One end of the sensing air channel is located at the bottom of the circuit board receiving groove and is positioned directly opposite the airflow sensor, while the other end of the sensing air channel is located on the side of the connecting portion away from the first receiving portion in the first direction.

[0010] In some examples, the connecting portion has a sealing element receiving groove on the side opposite to the first receiving portion in the first direction, and the conductive post penetrates the bottom of the sealing element receiving groove; The power supply assembly also includes a seal, which is disposed in the seal receiving groove and seals with the connection portion, and the conductive post is disposed through the seal along the first direction.

[0011] In some examples, the first receiving portion has a panel receiving groove on the other side in the second direction, and the power supply assembly further includes a display panel disposed in the panel receiving groove and electrically connected to the circuit board.

[0012] In some examples, a strip-shaped opening is provided at the connection between the first receiving portion and the second receiving portion. The strip-shaped opening connects the circuit board receiving groove and the panel receiving groove. The display panel is connected to the circuit board via a flexible circuit board, which passes through the strip-shaped opening.

[0013] In some examples, the power supply assembly further includes a housing that is fitted over the battery holder, and the negative terminal of the battery and at least one of the circuit boards are grounded to the housing.

[0014] In some examples, an elastic conductive element is sandwiched between the battery and the casing, and the elastic conductive element is electrically connected to the negative terminal of the battery and the casing, respectively.

[0015] In some examples, the second receiving portion has a clearance notch at one end in the first direction away from the first receiving portion, and the elastic conductive element is located in the clearance notch.

[0016] In some examples, the elastic conductive element includes conductive foam, the battery includes a cell body and a negative electrode tab, the negative electrode tab is connected to the cell body and is at least partially exposed outside the cell body, and the conductive foam covers at least the portion of the negative electrode tab exposed outside the cell body.

[0017] The beneficial effects of the technical solutions provided in this application include at least the following: By directly connecting the conductive block to one side of the circuit board and setting the conductive post on the conductive block, the conductive post only occupies the space on one side of the circuit board. This helps to reduce the overall size of the circuit board and conductive post in the thickness direction of the circuit board, thereby reducing the space occupied in the battery bracket. This makes the power supply component structure more compact and less prone to squeezing or bumping with other structures. Attached Figure Description

[0027] Figure 1 This is a schematic diagram of the structure of an aerosol generating device provided in an embodiment of this application, as shown below. Figure 1 As shown, the aerosol generating device 1000 includes an atomizer 100 and a power supply component 200, with the atomizer 100 and the power supply component 200 being detachably connected.

[0028] Figure 2 This is a schematic diagram of the structure of a power supply component provided in an embodiment of this application. Figure 1 ,like Figure 2 As shown, the power supply assembly 200 includes a battery holder 210, a circuit board 220, and a battery 230. The battery holder 210 includes a connecting portion 211, a first receiving portion 212, and a second receiving portion 213 connected sequentially along a first direction X. The connecting portion 211 is used to connect to the atomizer 100. The circuit board 220 is disposed in the first receiving portion 212, and the battery 230 is disposed in the second receiving portion 213. The battery 230 is electrically connected to the circuit board 220.

[0029] The circuit board 220 can be used to control the battery 230 to supply power to the atomizer 100, and to control the atomizing assembly 20 to start or stop working.

[0030] like Figure 2 As shown, the circuit board 220 can be arranged perpendicular to the second direction Y. A conductive block 240 can be connected to the surface of the circuit board 220 on one side in the second direction Y, and a conductive post 250 is connected to the conductive block 240. The conductive post 250 passes through the connecting part 211 along the first direction X, and the conductive post 250 is used for electrical connection with the atomizer 100.

[0031] The second direction Y can be perpendicular to the first direction X. For example, the second direction Y can be the thickness direction or the width direction of the aerosol generating device 1000.

[0032] When the atomizer 100 is installed on the power supply assembly 200, the conductive post 250 can abut against the electrode 18 on the fixed base 12, so that the power supply assembly 200 and the atomizer assembly 20 form an electrical connection.

[0033] The circuit board 220 can be arranged perpendicular to the second direction Y, that is, the thickness direction of the circuit board 220 can be parallel to the second direction Y. The conductive post 250 is arranged on one side of the thickness direction of the circuit board 220, and the conductive post 250 extends along the first direction X, that is, the conductive post 250 is not arranged along the thickness direction of the circuit board 220.

[0034] In related technologies, when setting conductive posts 250 that are not perpendicular to the circuit board 220, the conductive posts 250 are typically configured as two segments bent at 90°, with a notch at the edge of the circuit board 220. One segment of the conductive post 250 is inserted into the notch, with the segment within the notch aligned with the thickness direction of the circuit board 220, while the other segment is parallel to the circuit board 220 and spaced apart. The segment within the notch is then soldered to the circuit board 220. This structure not only requires notches on the circuit board 220, but also has both ends of the segment within the notch protruding from the notch in the thickness direction of the circuit board 220. The conductive posts 250 occupy space on both sides of the circuit board 220, resulting in a larger overall size of the circuit board 220 and conductive posts 250 in the thickness direction of the circuit board 220, and thus occupying more space within the battery holder 210. The end of the segment within the notch protruding from the circuit board 220 may interfere with other structures, or even cause squeezing or impact, leading to the conductive post 250 becoming loose.

[0035] In this embodiment, by directly connecting the conductive block 240 to one side of the circuit board 220 and setting the conductive post 250 on the conductive block 240, the conductive post 250 occupies only one side of the space of the circuit board 220. This helps to reduce the overall size of the circuit board 220 and the conductive post 250 in the thickness direction of the circuit board 220, thereby reducing the space occupied in the battery bracket 210. This makes the power supply component 200 structure more compact and less prone to squeezing or collision with other structures.

[0036] For example, the conductive block 240 can be soldered onto the circuit board 220, for example, by surface mount soldering.

[0037] The conductive post 250 and the conductive block 240 can be soldered together or are an integral structure. In some examples, the conductive post 250 can be a pogo pin.

[0038] like Figure 2 As shown, the circuit board 220 may have multiple conductive blocks 240, each of which is connected to a conductive post 250. The power supply assembly 200 may also include an insulating cover 260 that encloses the multiple conductive blocks 240.

[0039] For example, the insulating cover 260 may be formed using insulating adhesive.

[0040] The insulating cover 260 can fix and insulate multiple conductive blocks 240, reducing the risk of short circuits between adjacent conductive blocks 240.

[0041] The insulating cover 260 can also be connected to the circuit board 220 to cover the connection between the conductive block 240 and the circuit board 220, which helps to improve the reliability of the connection between the conductive block 240 and the circuit board 220.

[0042] Figure 3 This is a schematic diagram of the structure of a power supply component provided in an embodiment of this application. Figure 2 ,like Figure 3 As shown, the first receiving portion 212 may have a circuit board receiving groove 2121 on one side in the second direction Y, and the connecting portion 211 may have a strip-shaped through hole 2111 extending through the connecting portion 211 along the first direction X. The strip-shaped through hole 2111 communicates with the circuit board receiving groove 2121, and the length direction of the strip-shaped through hole 2111 is along the second direction Y. The circuit board 220 is disposed in the circuit board receiving groove 2121, and the conductive post 250 passes through the strip-shaped through hole 2111.

[0043] Figure 4 This is a schematic diagram illustrating the fit between a strip-shaped through-hole and a conductive post, as provided in an embodiment of this application. Figure 4 As shown, the strip-shaped through holes 2111 and the conductive posts 250 can be arranged in a one-to-one correspondence, that is, each strip-shaped through hole 2111 is provided with a conductive post 250, and different conductive posts 250 are provided in different strip-shaped through holes 2111. Alternatively, several conductive posts 250 can correspond to one strip-shaped through hole 2111, that is, several conductive posts 250 are provided in one strip-shaped through hole 2111.

[0044] The through-hole 2111 provides assembly space for the conductive posts 250, facilitating the assembly of the circuit board 220 onto the battery holder 210. When placing the circuit board 220 into the circuit board receiving slot 2121, one end of the circuit board 220 with the conductive posts 250 can be first inserted into the circuit board receiving slot 2121, allowing multiple conductive posts 250 to be inserted at an angle into the through-hole 2111. Then, the end of the circuit board 220 furthest from the connecting portion 211 is gradually placed into the circuit board receiving slot 2121. Since the length direction of the through-hole 2111 is along the second direction Y, during this process, the conductive posts 250 can deflect from an angled insertion state along the through-hole 2111 to a state along the first direction X, completing the assembly of the circuit board 220.

[0045] As an example, the conductive block 240 may be disposed on the side of the circuit board 220 facing the bottom of the circuit board receiving groove 2121.

[0046] Since the conductive block 240 protrudes from the surface of the circuit board 220, the conductive block 240 is placed on the side of the circuit board 220 facing the bottom of the circuit board receiving groove 2121, so that no components protrude from the side of the circuit board 220 away from the bottom of the circuit board receiving groove 2121. This can prevent the protruding conductive block 240 from colliding or being squeezed with other structures, and can reduce the risk of the conductive block 240 becoming loose from the surface of the circuit board 220.

[0047] like Figure 2 As shown, an airflow sensor 270 may be provided on the side of the circuit board 220 facing the bottom of the circuit board receiving groove 2121. A sensing air passage 214 may be provided on the battery bracket 210. One end of the sensing air passage 214 is located at the bottom of the circuit board receiving groove 2121 and is positioned directly opposite the airflow sensor 270. The other end of the sensing air passage 214 is located on the side of the connecting portion 211 facing away from the first receiving portion 212 in the first direction X.

[0048] After the atomizer 100 is connected to the power supply component 200, the sensing air passage 214 can connect with the third sensing air hole 151, the second sensing air hole 121, the air guide tube 13, and the first sensing air hole 113 in the liquid storage component 10 to form a sensing air path. When the user inhales, the airflow sensor 270 can detect changes in air pressure through this sensing air path, thereby triggering the power supply component 200 to work.

[0049] By directly mounting the airflow sensor 270 on the surface of the circuit board 220, space can be saved. Furthermore, the airflow sensor 270 is also mounted on the side of the circuit board 220 facing the bottom of the circuit board receiving groove 2121, which can prevent the protruding airflow sensor 270 from bumping or being squeezed by other structures, thus reducing the risk of damage to the airflow sensor 270.

[0050] In some examples, the connecting portion 211 may have a sealing groove 2112 on the side facing away from the first receiving portion 212 in the first direction X, and the conductive post 250 penetrates the bottom of the sealing groove 2112. The power supply assembly 200 may also include a seal 280, which is disposed in the sealing groove 2112 and sealably engages with the connecting portion 211, and the conductive post 250 is disposed through the seal 280 along the first direction X.

[0051] The seal 280 can seal the position where the conductive post 250 passes through the connection 211, reducing the risk of condensate or aerosol matrix in the atomizer 100 entering the power supply assembly 200 along the conductive post 250.

[0052] like Figure 4 As shown, the connecting part 211 may also be provided with a magnetic element 2113. As an example, magnetic elements 2113 may be provided on opposite sides of the sealing element receiving groove 2112, and the magnetic elements 2113 may be used to attract the atomizer 100. For example, the aforementioned bottom cover 15 may be attracted, thereby magnetically connecting the atomizer 100 and the power supply assembly 200.

[0053] like Figure 3 As shown, the first receiving portion 212 has a circuit board receiving groove 2121 on one side in the second direction Y, and a panel receiving groove 2122 on the other side in the second direction Y. The power supply assembly 200 may also include a display panel 290, which is disposed in the panel receiving groove 2122 and is electrically connected to the circuit board 220.

[0054] For example, the display panel 290 can be used to display battery level, operating status, power level, number of suction ports, or other information.

[0055] The display panel 290 and the circuit board 220 are positioned on opposite sides of the first receiving portion 212, so that the display panel 290 and the circuit board 220 are separated by the first receiving portion 212. This can prevent interference between the display panel 290 and the circuit board 220 during assembly, or prevent squeezing or bumping between them.

[0056] The display panel 290 and the circuit board 220 can be connected via a flexible circuit board 291. For example, a strip-shaped opening 215 can be provided at the connection between the first receiving portion 212 and the second receiving portion 213, the strip-shaped opening 215 connecting the circuit board receiving groove 2121 and the panel receiving groove 2122. The flexible circuit board 291 passes through the strip-shaped opening 215.

[0057] By providing a strip opening 215, the flexible circuit board 291 can pass through the inside of the battery bracket 210 and connect the display panel 290 and the circuit board 220, which helps to reduce external wiring and lowers the risk of the flexible circuit board 291 being squeezed or scratched.

[0058] In some examples, flexible circuit board 220 and circuit board 220 can be connected by connectors, such as board-to-board connectors.

[0059] like Figure 3 As shown, the power supply assembly 200 may further include a housing 300, which is fitted over the battery holder 210. At least one of the negative terminal of the battery 230 and the circuit board 220 may be grounded to the housing 300.

[0060] The housing 300 can be used as part of a grounding conductive structure to connect at least one of the negative terminal of the battery 230 and the circuit board 220 to the housing 300, thereby grounding the circuit structure.

[0061] The power supply component 200 can usually be charged. During the process of connecting or disconnecting the power supply component 200 from the charging device, spike pulses will be generated, which may damage the circuit structure of the power supply component 200. By grounding the circuit board 220 or the battery 230, the circuit structure of the power supply component 200 can be protected, reducing the risk of the power supply component 200 being damaged by spike pulses.

[0062] Figure 5 This is an assembly diagram of an elastic conductive component provided in an embodiment of this application. Figure 5 The outer casing 300 is omitted from the text, such as... Figure 5 As shown, an elastic conductive element 310 may be sandwiched between the battery 230 and the outer casing 300. The elastic conductive element 310 is electrically connected to the negative terminal of the battery 230 and the outer casing 300 respectively.

[0063] The battery 230 may include a cell body and a negative electrode tab, the negative electrode tab being connected to the cell body and at least partially exposed outside the cell body.

[0064] The elastic conductive element 310 can form an elastic conductive connection between the battery 230 and the casing 300, which can not only compensate for the assembly tolerance between the battery 230 and the casing 300, but also maintain stable grounding when the battery 230 is slightly displaced. Furthermore, the elasticity of the elastic conductive element 310 also plays a protective role, providing a certain degree of buffering when the power supply component 200 is subjected to external impacts, reducing the impact on the battery 230 and making it less likely for the battery 230 to collide with the casing 300.

[0065] like Figure 5As shown, the second receiving portion 213 may have a clearance notch 2131 at one end away from the first receiving portion 212 in the first direction X, and the elastic conductive member 310 is located in the clearance notch 2131.

[0066] The clearance notch 2131 exposes the battery 230 and provides installation space for the elastic conductive element 310, allowing the elastic conductive element 310 to contact both the battery 230 and the housing 300.

[0067] In some examples, the resilient conductive element 310 may include conductive foam. The conductive foam may cover at least a portion of the negative electrode tab exposed outside the cell body.

[0068] The conductive foam is elastic and conductive, allowing it to adhere to the negative electrode tab over a larger area. This improves the grounding stability between the negative electrode tab and the outer casing 300, and reduces the risk of poor contact due to localized point contact. Furthermore, the soft material of the conductive foam provides protection for the negative electrode tab after covering it, preventing it from breaking or loosening due to external pulling.

[0069] Figure 6 This is a schematic diagram of the internal structure of an atomizer provided in an embodiment of this application, as shown below. Figure 6 As shown, the atomizer 100 includes a liquid storage assembly 10 and an atomizing assembly 20. The liquid storage assembly 10 stores an aerosol matrix, and the atomizing assembly 20 is disposed within the liquid storage assembly 10. The atomizing assembly 200 heats the aerosol matrix in the liquid storage assembly 10 to form an aerosol. A power supply assembly 200 supplies power to the atomizing assembly 20 so that the atomizing assembly 20 generates heat after being powered on.

[0070] Figure 7 This is a schematic diagram of the structure of a liquid storage component provided in an embodiment of this application, as shown below. Figure 7 As shown, the liquid storage assembly 10 includes a liquid storage tank housing 11, a fixed base 12, and a gas guide pipe 13. For ease of demonstration, Figure 7 At least part of the structure of the liquid storage tank shell 11 is omitted.

[0071] The liquid storage housing 11 has a first end 111 and a second end 112 opposite to each other in a first direction X. The first direction X can be the length direction of the liquid storage housing 11 or the insertion direction of the atomizer 100 and the power supply component 200. The first end 111 can be the end of the liquid storage housing 11 away from the power supply component 200, and the second end 112 can be the end of the liquid storage housing 11 close to the power supply component 200.

[0072] The first end 111 of the liquid storage tank housing 11 is provided with a first sensing air hole 113 and a suction nozzle 114, and the second end 112 of the liquid storage tank housing 11 is open. The fixed base 12 is connected to the second end 112 of the liquid storage tank housing 11 to close the second end 112 of the liquid storage tank housing 11.

[0073] Figure 8 yes Figure 7 An enlarged diagram of point A in the diagram, as shown below. Figure 8 As shown, the fixed base 12 is provided with a second sensing air hole 121, and an elastic sealing ring 14 is provided in the second sensing air hole 121. The air guide tube 13 is provided in the liquid storage tank shell 11. One end of the air guide tube 13 is connected to the first sensing air hole 113, and the other end of the air guide tube 13 is inserted into the elastic sealing ring 14, and the air guide tube 13 and the elastic sealing ring 14 are sealed together.

[0074] The first sensing vent 113, the air guide tube 13, and the second sensing vent 121 can together form part of the sensing air path. When the user inhales through the nozzle 114, the negative pressure generated by the inhalation can be transmitted through the first sensing vent 113, the air guide tube 13, and the second sensing vent 121 to the airflow sensor in the power supply component 200, thereby triggering the power supply component 200 to supply power to the atomizing component 20. The end of the air guide tube 13 near the fixed base 12 is sealed to the fixed base 12 by an elastic sealing ring 14, rather than being rigidly fitted to the hole wall of the second sensing vent 121. When the air guide tube 13, the fixed base 12, or the liquid storage tank housing 11 undergoes thermal expansion and contraction due to temperature changes, the elastic sealing ring 14 can undergo elastic deformation to compensate for the dimensional changes between the air guide tube 13 and the fixed base 12, thereby reducing the risk of aerosol matrix leakage caused by gaps at the second sensing vent 121.

[0075] For example, the elastic sealing ring 14 can be a silicone part, a rubber part, or other sealing element with elastic sealing capability. The elastic sealing ring 14 can be annular, with its outer wall sealingly engaging with the wall of the second sensing vent 121, and its inner wall sealingly engaging with the outer wall of the air guide tube 13. In this way, the elastic sealing ring 14 can both prevent the aerosol matrix in the liquid storage tank shell 11 from entering the gap between the second sensing vent 121 and the air guide tube 13, and ensure the airtightness of the sensing air path.

[0076] like Figure 8 As shown, an annular rib 141 may be provided on the inner wall of the elastic sealing ring 14, and the annular rib 141 abuts against the outer wall of the air guide tube 13.

[0077] The annular rib 141 can extend circumferentially along the elastic sealing ring 14. By providing the annular rib 141, the local contact area between the elastic sealing ring 14 and the air guide tube 13 can be reduced, making the elastic sealing ring 14 easier to deform, increasing the local compression, and making the elastic sealing ring 14 more reliably press against the outer wall of the air guide tube 13, thereby improving the sealing stability.

[0078] In some examples, a single annular rib 141 may be provided. In other possible implementations, multiple annular ribs 141 may be provided at intervals along the first direction X. Multiple annular ribs 141 can form a multi-layer sealing structure to further reduce the risk of liquid or gas leakage.

[0079] like Figure 8 As shown, the second sensing air hole 121 may be provided with an inner flange 122, and the elastic sealing ring 14 may be located on the side of the inner flange 122 away from the first sensing air hole 113. The inner flange 122 is clearance-fitted with the air guide tube 13.

[0080] The inner flange 122 can be used to limit the elastic sealing ring 14, reducing the risk of the elastic sealing ring 14 moving towards the side closer to the first sensing air hole 113. The inner flange 122 and the air guide tube 13 are in clearance fit, so that a rigid pressing relationship is not formed between the air guide tube 13 and the inner flange 122. When the air guide tube 13 expands due to heat or contracts due to cooling, it is not easy to directly squeeze the fixed base 12, which helps to reduce the risk of cracks or gaps between the air guide tube 13 and the fixed base 12 due to repeated thermal expansion and contraction.

[0081] As an example, the inner flange 122 may be located at the end of the second sensing vent 121 near the first sensing vent 113.

[0082] like Figure 8 As shown, the elastic sealing ring 14 may be provided with a first rib 142 on the side near the inner flange 122. The first rib 142 is annular and can abut against the inner flange 122. By utilizing the compression between the first rib 142 and the inner flange 122, a better seal can be formed between the elastic sealing ring 14 and the inner flange 122, further reducing the risk of leakage from the second sensing vent 121.

[0083] In some examples, the liquid storage assembly 10 may also include a bottom cover 15, which is fitted onto the second end 112 of the liquid storage tank housing 11. The bottom cover 15 makes the connection between the fixed base 12 and the liquid storage tank housing 11 more stable and secure, preventing the fixed base 12 from becoming loose.

[0084] The elastic sealing ring 14 can be sandwiched between the bottom cover 15 and the inner flange 122. This allows the inner flange 122 and the bottom cover 15 to limit the elastic sealing ring 14 from both sides in the first direction X, so that the elastic sealing ring 14 is stably held in the second sensing vent 121, reducing the risk of the elastic sealing ring 14 coming off or shifting from the second sensing vent 121.

[0085] A third sensing vent 151 may be provided on the bottom cover 15, directly opposite the second sensing vent 121. The third sensing vent 151 is connected to the second sensing vent 121, and the diameter of the third sensing vent 151 may be smaller than the diameter of the second sensing vent 121.

[0086] The third sensing vent 151 can serve as an exposed opening of the sensing air path at the bottom of the liquid storage assembly 10. The third sensing vent 151 is used to communicate with the sensing air path of the power supply assembly 200 when the atomizer 100 is connected to the power supply assembly 200. The diameter of the third sensing vent 151 is smaller than the diameter of the second sensing vent 121, so that the bottom cover 15 forms a stop structure around the third sensing vent 151. This stop structure can hold the elastic sealing ring 14 from the side of the elastic sealing ring 14 away from the inner flange 122, thereby improving the installation reliability of the elastic sealing ring 14.

[0087] like Figure 8 As shown, a second rib 143 may be provided on the side of the elastic sealing ring 14 away from the inner flange 122. The second rib 143 is annular and can abut against the bottom cover 15. The second rib 143 can surround the third sensing vent 151. By using the compression between the second rib 143 and the bottom cover 15, a better seal can be formed between the elastic sealing ring 14 and the bottom cover 15, further reducing the risk of leakage from the second sensing vent 121.

[0088] In some examples, the bottom cover 15 may be a ferromagnetic component, such as an iron component, a steel component, or a composite component containing a ferromagnetic material.

[0089] The power supply assembly 200 and the atomizer 100 can be magnetically connected to improve the convenience and stability of the connection between the atomizer 100 and the power supply assembly 200. A magnetic component can be incorporated into the power supply assembly 200. When the bottom cover 15 is made of ferromagnetic material, the atomizer 100 can be magnetically connected to the magnetic component in the power supply assembly 200 via the bottom cover 15, eliminating the need for a magnetic component within the atomizer 100 and saving internal space.

[0090] like Figure 6 As shown, a limiting stop 115 may be provided in the first sensing air hole 113, and the end face of the air guide tube 13 inserted in the first sensing air hole 113 abuts against the limiting stop 115.

[0091] The limiting stop 115 can restrict the position of the air guide tube 13 in the first direction X to prevent the air guide tube 13 from extending out of the first sensing air hole 113 into the liquid storage tank shell 11 during the assembly process.

[0092] The air guide tube 13 can be interference-fitted with the first sensing air hole 113, thereby directly fixing the air guide tube 13 through the first sensing air hole 113. The first sensing air hole 113 is located at the first end 111 of the liquid storage tank shell 11 near the suction nozzle 114. The temperature change at the first sensing air hole 113 is small, and it is less affected by thermal expansion and contraction. Fixing the air guide tube 13 directly through the first sensing air hole 113 is simpler and less costly.

[0093] As an example, the air guide tube 13 and the first sensing air hole 113 can be riveted together, so that the end of the air guide tube 13 near the first end 111 is fixedly connected to the liquid storage tank shell 11.

[0094] The riveting connection method is simple in process and has good sealing performance, which can make the air pipe 13 and the hole wall of the first sensing air hole 113 have good air tightness.

[0095] In some other possible implementations, an elastic sealing ring may also be provided in the first sensing vent 113, thereby sealing the gap between the air guide tube 13 and the wall of the first sensing vent 113 through the elastic sealing element in the first sensing vent 113, compensating for the dimensional changes between the air guide tube 13 and the liquid storage tank shell 11, and further reducing the risk of leakage.

[0096] like Figure 6 As shown, an air guide groove 1131 can also be provided between the first sensing air hole 113 and the suction nozzle 114. The air guide groove 1131 connects the first sensing air hole 113 and the suction nozzle 114, so that during the user's suction process, the airflow in the first sensing air hole 113 can enter the suction nozzle 114 through the air guide groove 1131, which can prevent the first sensing air hole 113 from being blocked and causing poor airflow.

[0097] like Figure 7 As shown, a partition plate 116 may be provided in the liquid storage tank housing 11. One side of the partition plate 116 and the inner wall of the liquid storage tank housing 11 form an air intake channel 117 extending along the first direction X. Figure 6 As shown, the two ends of the air intake channel 117 are connected to the first sensing air hole 113 and the second sensing air hole 121, respectively, and the air guide pipe 13 is disposed in the air intake channel 117. The shell wall of the liquid storage tank housing 11 may be provided with an air inlet 118 that communicates with the air intake channel 117. External air can enter the air intake channel 117 through the air inlet 118, and then enter the atomization channel 20a of the atomization component 20 to carry out the aerosol generated by the atomization component 20.

[0098] The liquid storage assembly 10 may further include a sealing base 16 for mounting the atomizing assembly 20, the sealing base 16 being disposed within the liquid storage chamber housing 11. The sealing base 16 is sealed to the side of the partition plate 116 opposite to the air inlet channel 117 and to the inner wall of the liquid storage chamber housing 11. The sealing base 16, the partition plate 116, and the liquid storage chamber housing 11 form a liquid storage chamber 119, which is used to store the aerosol matrix. An air guiding cavity 17 is formed between the sealing base 16 and the fixed base 12, the air guiding cavity 17 connecting the air inlet channel 117 and the atomizing channel 20a of the atomizing assembly 20.

[0099] The air intake channel 117, the air guide chamber 17, and the atomization channel 20a can form a main airflow channel, while the first sensing air hole 113, the air guide tube 13, and the second sensing air hole 121 can form a sensing air path for triggering the airflow sensor. In this embodiment, the main airflow channel and the sensing air path are arranged relatively independently, which is beneficial to improving the triggering accuracy of the airflow sensor 270 and reducing the risk that the aerosol matrix may enter the power supply component 200 through the sensing air path and affect the airflow sensor 270.

[0100] The air guide chamber 17 may also be provided with a liquid suction component 171, which can be used to absorb the liquid dripping from the atomizing component 20 into the air guide chamber 17, so as to further reduce the risk of liquid leakage to the outside of the atomizer 100.

[0101] In some examples, the partition 116 may be arc-shaped, and the partition 116 facing the side of the airway 13 may conform to at least a portion of the outer wall of the airway 13.

[0102] The partition plate 116, which fits against the outer wall of the vent pipe 13, provides support and limits the vent pipe 13, making its position within the liquid storage tank housing 11 more stable. It also facilitates easier alignment of the vent pipe 13 with the first sensing vent 113 during assembly. Simultaneously, the arc-shaped partition plate 116 adapts to the shape of the vent pipe 13, allowing for a more compact internal structure within the liquid storage tank housing 11.

[0103] like Figure 6 As shown, the mounting base 12 may be provided with a plurality of electrodes 18 for electrical connection with the atomizing assembly 20. Exemplarily, the electrodes 18 may be cold-forged parts, i.e., structural parts formed using a cold-forging process. For example, electrodes formed of brass using a cold-forging process.

[0104] like Figure 7As shown, the plurality of electrodes 18 includes at least one first electrode 181. The first electrode 181 includes a columnar portion 1811 and a sheet-like portion 1812, with one side of the sheet-like portion 1812 connected to one end of the columnar portion 1811 in the thickness direction. The columnar portion 1811 is disposed through the fixed base 12 and is used for electrical connection with the atomizing assembly 20. The side of the sheet-like portion 1812 facing away from the columnar portion 1811 is exposed on the surface of the fixed base 12 facing away from the first end 111 in the first direction X, and the sheet-like portion 1812 is used to abut against the conductive post 250 in the power supply assembly 200 for conduction when the atomizer 100 is connected to the power supply assembly 200.

[0105] Here, "exposed to" can be understood as being visible from the outside of the fixed base 12 or being contacted by other conductive structures. The side of the sheet portion 1812 facing away from the column portion 1811 can protrude from the surface of the fixed base 12, be flush with the surface of the fixed base 12, or be recessed relative to the surface of the fixed base 12; as long as the conductive structure in the power supply assembly 200 can contact the sheet portion 1812 and form an electrical connection, the sheet portion 1812 can be considered to be exposed to the surface of the fixed base 12.

[0106] The total number of electrodes 18 and their distribution on the fixed base 12 can be set according to different atomizers 100. The sheet-like portion 1812 has a large surface area, which is beneficial for contact with the conductive post 250 of the power supply assembly 200. Furthermore, the sheet-like portion 1812 can also form a large contact area with the fixed base 12, making the connection between the first electrode 181 and the fixed base 12 more secure.

[0107] Figure 9 yes Figure 6 An enlarged diagram of point B in the diagram, as shown below. Figure 9 As shown, at least a portion of the sheet-like portion 1812 can be embedded in the fixing base 12. The edge of the sheet-like portion 1812 opposite to the columnar portion 1811 may be provided with a chamfer 1813, and the fixing base 12 covers at least a portion of the chamfer 1813.

[0108] Embedding the sheet-like portion 1812 into the fixing base 12 increases the contact area between the sheet-like portion 1812 and the fixing base 12, making the connection between the first electrode 181 and the fixing base 12 more secure. By covering at least a portion of the chamfer 1813 with the fixing base 12, the bonding area between the first electrode 181 and the fixing base 12 can be further increased. Furthermore, the material of the fixing base 12 covering the chamfer 1813 can form a covering or retaining structure at the edge of the sheet-like portion 1812, thereby reducing the risk of the first electrode 181 detaching from the fixing base 12.

[0109] As an example, the first electrode 181 can be embedded in the fixed base 12. By using an insert molding process to make the first electrode 181 and the fixed base 12 as a whole, the connection between the first electrode 181 and the fixed base 12 can be made more secure, and the fixed base 12 can better cover the chamfer 1813.

[0110] In some examples, the side of the sheet portion 1812 facing away from the column portion 1811 may be flush with the surface of the fixed base 12 facing away from the first end 111 in the first direction X.

[0111] This makes the bottom surface of the fixed base 12 relatively flat, which is conducive to stable contact between the atomizer 100 and the power supply component 200. It also helps to reduce the risk of the plate part 1812 being scratched, deformed by pressure, or contaminated due to its protrusion, thus avoiding poor contact between the atomizer 100 and the power supply component 200.

[0112] Figure 10 This is a schematic diagram of the structure of a first electrode provided in an embodiment of this application, as shown below. Figure 10 As shown, the axis of the columnar portion 1811 can be eccentrically set relative to the geometric center of the sheet portion 1812.

[0113] The eccentric arrangement allows for greater flexibility in the space occupied by the first electrode 181 within the fixed base 12, facilitating avoidance of other structures. For example, the first electrode 181 can be located on the side of the sealed base 16 away from the liquid storage chamber 119 in the first direction X. The eccentric arrangement of the columnar portion 1811 allows it to avoid the inlet of the atomization channel 20a of the atomization assembly 20. This prevents the columnar portion 1811 from affecting the airflow into the atomization channel 20a and also prevents liquid dripping from the inlet of the atomization channel 20a from contaminating the first electrode 181.

[0114] For example, the distance between the axis of the columnar portion 1811 and the geometric center of the sheet portion 1812 can be 3mm to 10mm, for example, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, or 10mm.

[0115] In some examples, the plurality of electrodes 18 may further include a second electrode 182. The second electrode 182 may include a cylindrical portion 1821 and a contact portion 1822 arranged coaxially. The contact portion 1822 is connected to one end of the cylindrical portion 1821, and the contact portion 1822 and the cylindrical portion 1821 may be arranged coaxially. The second electrode 182 is disposed through the fixing base 12, wherein the contact portion 1822 may be embedded in the fixing base 12, and the surface of the contact portion 1822 away from the cylindrical portion 1821 may be exposed outside the fixing base 12.

[0116] like Figure 10 As shown, at least one outer wall of the columnar portion 1811 can be a plane.

[0117] Setting the outer side wall as a plane can restrict the rotation of the first electrode 181 relative to the fixed base 12. When the fixed base 12 is manufactured using an insert molding process, the first electrode 181 is placed in the mold, and the planar outer side wall of the columnar portion 1811 can limit the columnar portion 1811, improve the positional accuracy of the first electrode 181, and prevent the position of the first electrode 181 from shifting.

[0118] The columnar portion 1811 may also have at least one arc-shaped outer side wall, for example, at least one outer side wall may be a semi-cylindrical surface. The arc-shaped outer side wall facilitates better electrical connection with the atomizing assembly 20.

[0119] The atomizing component 20 can be housed within the liquid storage tank housing 11. (Refer to...) Figure 6 As shown, the atomizing assembly 20 may include an atomizing core cover 21, a liquid guiding component 22, a heating element 23, and a lead wire 24. The liquid guiding component 22 is sleeved over the heating element 23, and the atomizing core cover 21 is sleeved over the liquid guiding component 22. The lead wire 24 is connected to the heating element 23. The lead wire 24 is used to connect to the electrode 18. For example, the lead wire 24 can be attached to the outer wall of the columnar portion 1811 of the first electrode 181. Exemplarily, the lead wire 24 can be attached to the arc-shaped outer wall of the columnar portion 1811. The lead wire 24 can also be attached to the side wall of the cylindrical portion 1821 of the second electrode 182.

[0120] The atomizing core cover 21 provides space inside the liquid storage tank housing 11 to accommodate the liquid guiding component 22 and the heating component 23. The atomizing core cover 21 may be cylindrical, and an atomizing channel 20a extending axially along the atomizing core cover 21 is formed inside it. One end of the atomizing channel 20a is connected to the mouthpiece 114, and the other end is connected to the air guiding chamber 17.

[0121] The sidewall of the atomizing core outer cover 21 may have structures such as holes and slits to allow the aerosol generating matrix in the liquid storage tank shell 11 to enter the atomizing core outer cover 21 and be absorbed by the liquid guiding component 22. The heating element 23 is used to heat the aerosol generating matrix in the liquid guiding component 22, causing the aerosol generating matrix to vaporize.

[0122] The material and structure of the heating element 23 are not limited, as long as it can generate heat. For example, the heating element 23 may include at least one of heating mesh, heating film, heating wire, and heating plate.

[0123] The heating element 23 can be a metal structural component. For example, the heating element 23 can be formed of at least one material selected from stainless steel, nickel-chromium-aluminum alloy, nickel 50, titanium, and titanium alloy.

[0124] The heating element 23, made of metal, can withstand higher temperatures, which helps to extend the service life of the atomizing component 20.

[0125] As an example, the heating element 23 can be made of a material with TCR (Temperature Coefficient of Resistance) properties. For example, the heating element 23 can be made of a PTC (Positive Temperature Coefficient) material.

[0126] During the operation of the heating element, the temperature of the heating element 23 can be determined based on its resistance and the temperature coefficient of resistance. Methods for determining temperature based on resistance and the temperature coefficient of resistance can be found in relevant technologies.

[0127] The heating element 23 may be connected to a plurality of leads 24, and, by way of example, the leads 24 may be soldered to the heating element 23.

[0128] Lead 24 can be made of one of the following: nickel, silver, nickel alloy, silver alloy, nickel-coated copper composite material, or copper-coated nickel composite material.

[0129] The lead wire 24 made of the above-mentioned materials has good electrical conductivity, suitable for current transmission requirements. It also has a certain degree of corrosion resistance, able to resist oxidation and chemical corrosion to a certain extent, maintaining the stable performance of the lead wire 24. Furthermore, it has good mechanical properties, able to withstand a certain degree of tension and bending, making it suitable for applications requiring high mechanical strength.

[0130] In this embodiment, an elastic sealing ring 14 is provided in the second sensing air hole 121 of the fixed base 12, and one end of the air guide tube 13 near the fixed base 12 is inserted into the elastic sealing ring 14. The air guide tube 13 and the fixed base 12 can be elastically sealed through the elastic sealing ring 14. Compared with the method where both ends of the air guide tube 13 are rigidly riveted to the shell structure, the elastic sealing structure at the end near the bottom of the atomizer 100, where the temperature change is more obvious, can reduce the risk of sealing gaps after repeated thermal expansion and contraction, thereby reducing the possibility of aerosol matrix leaking from the second sensing air hole 121 to the power supply component 200.

[0131] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
