[0029] Figure 1 This is a schematic diagram of an aerosol generation device. Figure 1 As shown, the aerosol generating device includes an atomizer 100 and a power supply 200, with the atomizer 100 connected to the power supply 200.

[0030] The power supply 200 has an internal circuit structure, which varies depending on the required functions. For example, to implement a positioning function, the circuit structure may include a positioning module; to implement a child lock function, the circuit structure may include a child lock module. Adding more functional modules allows for more functions, but it also means higher operating costs. Different users have different functional needs, and restricting unnecessary functional modules constitutes waste.

[0031] To reduce user costs and minimize resource waste, this application provides a power supply 200. Figure 2 This is a schematic diagram of a power supply structure provided in an embodiment of this application, such as... Figure 2As shown, the power supply 200 includes a power supply module 20 and functional components 30. The functional components 30 and the power supply module 20 are detachably connected, allowing both to be replaced individually. For example, functional components 30 can be replaced with those having different functions according to the user's needs; or, if a functional component 30 is damaged, the power supply module 20 can be retained, and only the functional component 30 can be replaced. Users can choose the appropriate functional component 30 according to their needs, greatly reducing user costs and avoiding resource waste.

[0032] Figure 3 This is an exploded view of a power supply module provided in an embodiment of this application, as shown below. Figure 3 As shown, the power supply module 20 includes a power bracket 21 and a first circuit board 22. The power bracket 21 has a first side 211 and a second side 212 facing each other. The first side 211 of the power bracket 21 is connected to the atomizer 100, and the first side 211 of the power bracket 21 has a first mounting groove 21b in which the functional accessory 30 is detachably installed. The first circuit board 22 is located on the side of the power bracket 21 away from the first side 211; for example, the first circuit board 22 may be located on the second side 212 of the power bracket 21. The functional accessory 30 is electrically connected to the first circuit board.

[0033] By setting a power supply module 20 and a functional accessory 30 in the power supply 200, the power supply module 20 includes a power support 21 and a first circuit board 22. A first mounting slot 21b is set on the first side 211 of the power support 21, and the first circuit board 22 is set on the second side 212 of the power support 21. The functional accessory 30 is detachably installed using the first mounting slot 21b, so that the functional accessory 30 is electrically connected to the first circuit board 22. Users can select the functional accessory 30 with appropriate functions according to their own needs. When it is necessary to replace the functional accessory 30, the functional accessory 30 can be directly removed from the first mounting slot 21b, and the electrical connection between the functional accessory 30 and the first circuit board 22 can be disconnected. The operation is convenient and simple, which helps to reduce the operating cost of the aerosol generating device.

[0034] For example, the functional accessory 30 may include one of the following: a positioning module, a light-emitting module, a vibration module, a data transmission module, a child lock module, and a counting module. The positioning module may include a device with positioning function, such as a GPS chip; the light-emitting module may include a device with light-emitting function, such as an LED; the vibration module may include a device with vibration function, such as a vibration motor; the data transmission module may include a device with wireless transmission function, such as a Bluetooth module; the child lock module may include a circuit with child lock function, the structure of which can refer to related technologies; the counting module may include a circuit for recording the number of suctions, the structure of which can refer to related technologies.

[0035] The above functions are just examples, and the functions of the functional accessory 30 may not be limited to the examples listed above.

[0036] When assembling the functional component 30 and the power supply module 20, the functional component 30 is placed in the first mounting slot 21b, and the component 31 is electrically connected to the first circuit board 22.

[0037] The power supply module 20 may include a power support 21, a first housing 24, and a circuit structure. The first housing 24 has an opening 24a communicating with its interior. The power support 21 is disposed inside the first housing 24, with its first side 211 facing the opening 24a. The opening 24a is used to connect with the atomizer 100.

[0038] The circuit structure may include a battery 23 and a first circuit board 22, with the battery 23 electrically connected to the first circuit board 22. Figure 4 This is a schematic diagram of the structure of a power supply module provided in an embodiment of this application. Figure 1 , Figure 4 At least the first outer shell 24 is omitted, such as Figure 4 As shown, the battery 23 and the first circuit board 22 are both disposed on the second side 212 of the power supply bracket 21, and the battery 23 is disposed on the side of the first circuit board 22 away from the first mounting groove 21b.

[0039] Figure 5 This is a schematic diagram of the structure of a power supply module provided in an embodiment of this application. Figure 2 ,like Figure 5 As shown, the bottom of the first mounting groove 21b may be provided with a hollow structure, and the first circuit board 22 is provided with a first electrical connection structure 221 opposite to the hollow structure. The first electrical connection structure 221 is used to contact the functional accessory 30 to form an electrical connection.

[0040] As an example, the cutout structure may include a first through hole 21c.

[0041] By providing a first through hole 21c that penetrates the bottom of the first mounting groove 21b, when the functional component 30 is installed into the first mounting groove 21b, the first electrical connection structure 221 on the first circuit board 22 can contact the functional component 30, thereby forming an electrical connection between the functional component 30 and the first circuit board 22.

[0042] In some possible implementations, the first mounting slot 21b can also be configured as a through slot, that is, the first mounting slot 21b passes through the first side 211 and the second side 212 of the power supply bracket 21, so that the first circuit board 22 is directly exposed in the first mounting slot 21b, and the functional accessory 30 contacts the first circuit board 22 to form an electrical connection when the functional accessory 30 is installed.

[0043] The first electrical connection structure 221 may include at least one of a first conductive post 2211 and a first contact electrode 2212.

[0044] As an example, such as Figure 5 As shown, in this example, the first electrical connection structure 221 includes a first conductive post 2211. One end of the first conductive post 2211 is electrically connected to the first circuit board 22, the first conductive post 2211 is inserted into the first through hole 21c, and the other end of the first conductive post 2211 is used to contact the functional accessory 30 to form an electrical connection.

[0045] The first conductive post 2211 extends out of the first through hole 21c and contacts the first conductive post 2211 when the functional component 30 is installed into the first mounting slot 21b. When the functional component 30 is disassembled, it separates from the first conductive post 2211. An electrical connection is formed through contact, which facilitates the assembly and disassembly of the functional component 30 and the power supply module 20.

[0046] For example, the first conductive post 2211 can be transitionally fitted with the first through hole 21c. For instance, the first conductive post 2211 and the first through hole 21c can be clearance fitted to facilitate the insertion of the first conductive post 2211 into the first through hole 21c.

[0047] As an example, the first conductive post 2211 can be a pogo pin. When the functional accessory 30 is installed into the first mounting slot 21b, the pogo pin is compressed and abuts against the functional accessory 30. The spring force of the pogo pin ensures good contact between the pogo pin and the functional accessory 30, reducing the risk of poor contact.

[0048] like Figure 5 As shown, the power supply module 20 may further include a third conductive post 222. One end of the third conductive post 222 can be connected to the first circuit board 22, and the other end of the third conductive post 222 passes through the power supply bracket 21 to the first side 211 of the power supply bracket 21. The third conductive post 222 is used to contact the atomizer 100 to form an electrical connection, thereby supplying power to the atomizer 100.

[0049] For example, the third conductive post 222 can be a spring needle, the spring force of which keeps the spring needle in good contact with the atomizer 100, reducing the risk of poor contact.

[0050] Multiple third conductive posts 222 can be provided. As an example, the power supply module 20 includes three third conductive posts 222. The three third conductive posts 222 are distributed outside the first mounting slot 21b.

[0051] like Figure 5As shown, the power supply module 20 may also include a first magnetic member 25, which is disposed in the first mounting groove 21b and is used to attract the functional accessory 30.

[0052] By setting the first magnetic suction component 25, the functional component 30 and the power supply module 20 are connected by magnetic attraction. This not only makes the installation of the functional component 30 more stable, but also helps the functional component 30 to be installed in place, avoiding misalignment of the functional component 30 during installation.

[0053] As an example, such as Figure 5 As shown, the bottom of the first mounting groove 21b may be provided with a second mounting groove 21d, and the first magnetic member 25 is accommodated in the second mounting groove 21d.

[0054] For example, the first magnetic member 25 can be attached to the second mounting groove 21d.

[0055] The second mounting slot 21d can restrain the first magnetic member 25 and prevent it from becoming loose. The second mounting slot 21d is arranged at the bottom of the first mounting slot 21b, so that during the installation of the functional component 30, the magnetic force on the functional component 30 is along the depth direction of the first mounting slot 21b, that is, in the same direction as the functional component 30 being placed into the first mounting slot 21b, thereby allowing the functional component 30 to be placed into the first mounting slot 21b more stably.

[0056] Figure 6 This is a schematic diagram of the structure of a power supply bracket provided in an embodiment of this application. Figure 1 ,like Figure 6 As shown, the first mounting groove 21b may include a main body 21e and two extensions 21f. The main body 21e is located between the two extensions 21f, and the main body 21e and the two extensions 21f are distributed along a first direction. The first direction may be perpendicular to the depth direction of the first mounting groove 21b.

[0057] For example, the first direction may be parallel to the width direction X of the power supply bracket 21 or parallel to the length direction Y of the power supply bracket 21. For example, in this example, the first direction is parallel to the width direction X of the power supply bracket 21.

[0058] Each of the two extensions 21f is provided with a second mounting groove 21d, and each second mounting groove 21d is provided with at least one first magnetic member 25.

[0059] A second mounting slot 21d is provided on each side of the main body 21e to accommodate the first magnetic member 25, so that the functional component 30 can be subjected to a more symmetrical magnetic force, which can make the functional component 30 more stable during installation. One or more first magnetic members 25 can be provided in each second mounting slot 21d.

[0060] As an example, the main body 21e can be circular, and the two extensions 21f can be symmetrically distributed about the axis of the main body 21e.

[0061] The first through hole 21c can be located in the main body 21e, and multiple first through holes 21c can be provided, which can be distributed along the circumferential direction of the main body 21e. As an example, three first through holes 21c can be provided, and the three first through holes 21c are rotationally symmetrical about the axis center of the main body 21e.

[0062] Figure 7 This is a schematic diagram of another power supply bracket provided in an embodiment of this application, as shown below. Figure 7 As shown, in the power supply bracket 21, the first side 211 of the power supply bracket 21 may also be provided with a protruding ridge 213, which is located at the edge of the first mounting groove 21b. The protruding ridge 213 may extend along the edge of the first mounting groove 21b.

[0063] During the use of the aerosol generating device, the atomizer 100 may leak, such as leakage of the aerosol generating matrix or condensate. The leaked liquid from the atomizer 100 may flow towards the power supply bracket 21. The protruding ridge 213 can prevent liquid adhering to the first side 211 of the power supply bracket 21 from flowing towards the first mounting groove 21b.

[0064] As an example, the protruding ridge 213 can be arranged around the first mounting groove 21b. This allows for the containment of liquid from multiple directions.

[0065] In some examples, the power supply module 20 may also include a third magnetic element 26, which may be disposed on a first side 211 or a second side 212 of the power supply bracket 21. The third magnetic element 26 is used to attract the atomizer 100.

[0066] Figure 8 This is a schematic diagram of the structure of a power supply bracket provided in an embodiment of this application. Figure 2 The figure shows the second side 212 of the power supply bracket 21, as an example, such as Figure 8 As shown, a fifth mounting slot 212a can be provided on the second side 212 of the power supply bracket 21, and a third magnetic member 26 can be provided in the fifth mounting slot 212a.

[0067] For example, the third magnetic member 26 can be attached to the fifth mounting groove 212a.

[0068] There can be two fifth mounting slots 212a, which can be located near the edge of the power supply bracket 21. The first mounting slot 21b can be located between the two fifth mounting slots 212a.

[0069] Reference Figure 3 As shown, a button 223 can also be connected to the first circuit board 22. A keycap 241 is provided on the first housing 24, and the keycap 241 is connected to the button 223. The keycap 241 is provided to facilitate pressing the button 223.

[0070] For example, button 223 may be located on the second side 212 of the first circuit board 22.

[0071] Figure 9 This is a schematic diagram of the structure of a functional accessory provided in an embodiment of this application. Figure 1 This functional accessory 30 can be applied to any of the aforementioned power supply modules 20. For example... Figure 9 As shown, the functional accessory 30 may include an accessory bracket 32 ​​and a component 31. The component 31 is disposed in the accessory bracket 32, which is used to mount the component 31 to the first mounting slot 21b, so that the component 31 is electrically connected to the first circuit board 22.

[0072] Component 31 is installed into accessory bracket 32. When the function of component 31 is needed, accessory bracket 32 ​​can be placed into the first mounting slot 21b of power supply module 20. Functional accessory 30 forms an independently detachable module. When the function of component 31 is no longer needed or when it is necessary to replace component 31 with another component, accessory bracket 32 ​​can be directly removed from the first mounting slot 21b for replacement, which helps to reduce the operating cost of aerosol generating device.

[0073] like Figure 9 As shown, component 31 may include a second circuit board 33 and an electronic component 35. The electronic component 35 is connected to the second circuit board 33, which is disposed in the accessory bracket 32.

[0074] Figure 10 This is a schematic diagram of the structure of a functional accessory provided in an embodiment of this application. Figure 2 ,like Figure 10 As shown, the second circuit board 33 has a second electrical connection structure 34 on the side away from the component 31. The second electrical connection structure 34 is used to form an electrical connection with the first circuit board 22.

[0075] By placing component 31 on the second circuit board 33 and using the second electrical connection structure 34 to electrically connect the second circuit board 33 and the first circuit board 22, component 31 is electrically connected to the first circuit board 22 in the power supply module 20.

[0076] When the functional component 30 is installed into the first mounting slot 21b, the second electrical connection structure 34 can contact the aforementioned first electrical connection structure 221, thereby forming an electrical connection between the functional component 30 and the first circuit board 22 of the power supply module 20.

[0077] The second electrical connection structure 34 may include at least one of the second contact electrode 341 and the second conductive post 342.

[0078] As an example, the second electrical connection structure 34 may include a second contact electrode 341, which may contact the aforementioned first conductive post 2211, thereby forming an electrical connection between the second circuit board 33 and the first circuit board 22.

[0079] Figure 11 This is a schematic diagram illustrating the cooperation between a first electrical connection structure and a second electrical connection structure provided in an embodiment of this application, as shown below. Figure 11 As shown, in some other possible implementations, the first electrical connection structure 221 may include a first contact electrode 2212, which is electrically connected to the first circuit board 22, and the second electrical connection structure 34 may include a second conductive post 342. When assembling the functional accessory 30 and the power supply module 20, the second conductive post 342 is inserted into the first through hole 21c at the bottom of the first mounting groove 21b, making contact with the first contact electrode 2212 on the first circuit board 22.

[0080] The second conductive post 342 can also be a spring pin to ensure high reliability of the electrical connection between the functional component 30 and the first circuit board 22 and reduce the risk of poor contact.

[0081] In some possible implementations, the functional accessory 30 can also be connected to the first circuit board 22 via a pluggable connector. In these examples, both the first electrical connection structure 221 and the second electrical connection structure 34 can be electrical connectors. For example, one of the first electrical connection structure 221 and the second electrical connection structure 34 can be a male connector, and the other can be a female connector.

[0082] like Figure 10 As shown, the accessory bracket 32 ​​has a third side 321 and a fourth side 322 facing each other, with the fourth side 322 facing the bottom of the first mounting groove 21b. The fourth side 322 of the accessory bracket 32 ​​may be provided with a third mounting groove 322a, in which the component 31 and the second circuit board 33 are disposed.

[0083] The third mounting slot 322a is provided to accommodate the second circuit board 33, ensuring stable installation of the second circuit board 33 and the component 31. The third mounting slot 322a also serves a protective function, reducing the risk of damage to the component 31 and the second circuit board 33, and helping to extend the service life of the functional component 30.

[0084] Figure 12 This is a schematic diagram of the internal structure of a functional accessory provided in an embodiment of this application. As an example, to ensure stable mounting of the second circuit board 33, [the following is an example]. Figure 12As shown, the bottom of the third mounting slot 322a may be provided with a fixing post 323, and the second circuit board 33 is connected to the fixing post 323 to prevent the second circuit board 33 from becoming loose.

[0085] The second circuit board 33 may have a third through hole 33a, through which the fixing post 323 can pass.

[0086] As an example, the third through hole 33a can be set on the edge of the second circuit board 33, and the edge of the second circuit board 33 can be provided with a notch 33b that communicates with the third through hole 33a. The notch 33b and the third through hole 33a form a slot, and the fixing post 323 can be locked in the slot to prevent the second circuit board 33 from becoming loose.

[0087] The bottom of the third mounting slot 322a may be provided with multiple fixing posts 323 at intervals. The multiple fixing posts 323 are respectively connected to the second circuit board 33 to make the installation of the second circuit board 33 more stable.

[0088] As an example, the bottom of the third mounting slot 322a can be provided with two fixing posts 323, and the two opposite sides of the second circuit board 33 are respectively provided with third through holes 33a, and the two fixing posts 323 are connected to the two third through holes 33a in a one-to-one correspondence.

[0089] like Figure 12 As shown, the end of the fixing post 323 away from the bottom of the third mounting groove 322a may be provided with a stop part 3231, and the stop part 3231 is located on the side of the second circuit board 33 away from the bottom of the third mounting groove 322a.

[0090] The stop part 3231 is provided at the end of the fixing post 323, which can restrict the movement of the second circuit board 33 along the fixing post 323 and prevent the second circuit board 33 from coming out of the third mounting groove 322a.

[0091] For example, the stop portion 3231 can be an outer flange provided at the end of the fixing post 323, and the outer diameter of the outer flange is larger than the diameter of the third through hole 33a. The stop portion 3231 can contact the second circuit board 33 to make the second circuit board 33 more stable and prevent the second circuit board 33 from becoming loose.

[0092] The stop portion 3231 can be formed using a hot-melt material. For example, the fixing post 323 can be formed using a hot-melt material. After the second circuit board 33 is installed into the third mounting groove 322a, the end of the fixing post 323 away from the bottom of the third mounting groove 322a is heated, causing the end of the fixing post 323 to deform and form the stop portion 3231. Alternatively, after the second circuit board 33 is installed into the third mounting groove 322a, hot-melt adhesive can be applied to the end of the fixing post 323. The hot-melt adhesive bonds the fixing post 323 and the second circuit board 33, and the stop portion 3231 is formed after the hot-melt adhesive cures.

[0093] In some other possible implementations, the stop 3231 can also be a retaining ring, which is snapped onto the end of the fixing post 323. For example, the stop 3231 can be a plastic retaining ring, which is less likely to scratch the second circuit board 33 or cause a short circuit in the second circuit board 33 compared to a metal retaining ring.

[0094] like Figure 12 As shown, the fourth side 322 of the accessory bracket 32 ​​may also be provided with a fourth mounting groove 322b. The functional accessory 30 may also include a second magnetic member 36, which is disposed in the fourth mounting groove 322b.

[0095] The second magnetic component 36 can be used to cooperate with the aforementioned first magnetic component 25 to allow the functional component 30 to be attached to the power supply module 20.

[0096] The first magnetic attractor 25, the second magnetic attractor 36, and the third magnetic attractor 26 can be structures made of iron, cobalt, nickel, or magnets that can generate a magnetic field or be attracted by a magnetic field. Furthermore, at least one of the first magnetic attractor 25 and the second magnetic attractor 36 is a magnet.

[0097] Multiple second magnetic elements 36 can be provided on the accessory bracket 32 ​​to ensure that the functional accessory 30 is attracted stably.

[0098] In this example, the fourth side 322 of the accessory bracket 32 ​​may be provided with at least two fourth mounting slots 322b, and the component 31 and the second circuit board 33 are located between the two fourth mounting slots 322b, that is, the components 31 are provided with fourth mounting slots 322b on both sides respectively.

[0099] The component 31 has a fourth mounting groove 322b on each side, and each fourth mounting groove 322b has at least one second magnetic attractor 36.

[0100] For example, the second magnetic member 36 can be attached to the fourth mounting slot 322b.

[0101] Second magnetic components 36 are provided on both sides of the fourth mounting slot 322b, so that the functional accessory 30 can be more stably attached to the power supply module 20.

[0102] like Figure 12 As shown, the edge of the third side 321 of the accessory bracket 32 ​​may also be provided with an outward protrusion 324, which extends outward from the edge of the third side 321, that is, the outward protrusion 324 protrudes in a direction away from the center of the accessory bracket 32. The outward protrusion 324 is located outside the first mounting groove 21b when the accessory bracket 32 ​​is installed in the first mounting groove 21b.

[0103] The protrusion 324 facilitates the disassembly and installation of the functional component 30. When installing the functional component 30, the protrusion 324 can be pinched to insert the component bracket 32 ​​into the first mounting groove 21b. When disassembling the functional component 30, the protrusion 324 located outside the first mounting groove 21b can be pinched to remove the functional component 30.

[0104] As an example, the accessory bracket 32 ​​may have two protrusions 324, which may be located at the opposite two edges of the third side 321 of the accessory bracket 32. The two protrusions 324 extend in a direction away from each other. When disassembling and installing the functional accessory 30, the two protrusions 324 can be pinched with two fingers for installation or disassembly.

[0105] When the functional accessory 30 is installed into the first mounting slot 21b, there may be a gap between the protrusion 324 and the power bracket 21 to facilitate the removal of the functional accessory 30 when disassembling it.

[0106] This application also provides an aerosol generating device, which may include an atomizer 100 and a power supply 200, wherein the atomizer 100 and the power supply 200 are detachably connected.

[0107] The power supply 200 includes the aforementioned power supply module 20 and the aforementioned functional component 30. The functional component 30 is disposed in the first mounting slot 21b, and the component 31 is electrically connected to the first circuit board 22.

[0108] During the use of the aerosol generator, users can select and use the appropriate functional accessory 30 according to their own needs. When it is necessary to replace the functional accessory 30, the atomizer 100 can be disassembled, the functional accessory 30 can be removed from the first mounting slot 21b, and then a new functional accessory 30 can be installed, reducing the user's operating costs.

[0109] 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.
