[0002] A common aerosol generating device includes an atomizer and a power supply assembly. The atomizer is connected to the power supply assembly. During operation, the power supply assembly supplies power to the atomizer.

[0003] The atomizer has a mouthpiece at one end. During the process of a user inhaling through the mouthpiece, the air pressure inside the aerosol generating device changes. The aerosol generating device can work in response to the change in air pressure.

[0004] The change in air pressure inside the aerosol generating device is detected by a microphone in the power supply assembly. The microphone is arranged in a housing of the power supply assembly and is in communication with the atomizer through an air inlet hole. The air inlet hole is relatively short, and the microphone is relatively close to the atomizer. A small part of the aerosol generated in the atomizer may enter the microphone and condense, causing the microphone to malfunction, thereby affecting the normal operation of the aerosol generating device. SUMMARY

[0005] The embodiments of the present application provide a power supply assembly of an aerosol generating device and an aerosol generating device, which can reduce the risk of aerosol entering the microphone and condensing, causing the microphone to malfunction. The technical solutions are as follows:

[0006] In a first aspect, the embodiments of the present application provide a power supply assembly of an aerosol generating device, which includes a bracket, a first sealing gasket and a second sealing gasket.

[0007] The bracket includes an atomizer connecting portion and a microphone mounting portion connected together. The atomizer connecting portion has an atomizer connecting groove. The microphone mounting portion is located at the bottom of the atomizer connecting groove. The microphone mounting portion has a gas guide groove extending away from the atomizer connecting groove.

[0008] The first sealing gasket has a first gas guide hole. The first sealing gasket is located at one end of the gas guide groove close to the atomizer connecting groove. The first gas guide hole is in communication with the atomizer connecting groove and the gas guide groove.

[0009] The second sealing gasket has a microphone accommodating groove and a second gas guide hole. The second sealing gasket is located at one end of the gas guide groove away from the atomizer connecting groove. The second gas guide hole is in communication with the microphone accommodating groove and the gas guide groove.

[0010] In some examples, the gas guide groove is arc-shaped.

[0011] In some examples, the microphone mounting portion has a first gasket accommodating groove located at one end of the air guide groove close to the atomizer connecting groove, and the first gasket is inserted into the first gasket accommodating groove and is in interference fit with the first gasket accommodating groove.

[0012] In some examples, the first gasket includes a gasket body having a first groove located at one side of the gasket body close to the atomizer connecting groove, and the first air guide hole is located at the groove bottom of the first groove.

[0013] In some examples, the first gasket further includes an elastic ridge located on the surface of the gasket body and arranged at least around the first groove.

[0014] In some examples, the microphone mounting portion has a second gasket accommodating groove located at one end of the air guide groove away from the atomizer connecting groove.

[0015] The second gasket is located at one side of the microphone mounting portion, and the second gasket is partially inserted into the second gasket accommodating groove.

[0016] In some examples, the first gasket accommodating groove penetrates through the microphone mounting portion; and / or, the second gasket accommodating groove penetrates through the microphone mounting portion.

[0017] In some examples, the power supply assembly further includes a sealing sheet located at one side of the microphone mounting portion, and the sealing sheet is attached to the surface of the microphone mounting portion to seal at least one of the first gasket accommodating groove, the second gasket accommodating groove, and the air guide groove.

[0018] In some examples, the power supply assembly further includes a circuit board located at one side of the second gasket away from the microphone mounting portion, and a microphone located in the microphone accommodating groove and connected to the circuit board.

[0019] In a second aspect, the embodiments of the present application further provide an aerosol generating device, which includes an atomizer and any one of the power supply assemblies of the first aspect, and the atomizer is partially located in the atomizer connecting groove.

[0020] The technical solutions provided by the embodiments of the present application have at least the following beneficial effects:

[0021] The atomizer is connected by setting an atomizer connecting groove on the atomizer connecting part of the support. The air guide groove is set on the microphone mounting part, extends in the direction away from the atomizer connecting groove, and is communicated with the atomizer connecting groove through the first air guide hole of the first sealing pad at one end of the air guide groove. The air guide groove is communicated with the microphone in the microphone containing groove through the second air guide hole of the second sealing pad at the other end of the air guide groove. The air pressure in the air guide groove changes during the user inhales through the suction nozzle. The aerosol generated in the atomizer needs to pass through the first air guide hole, the air guide groove and the second air guide hole to reach the microphone, so the path is long. Before reaching the microphone, the aerosol may condense on the hole wall of the first air guide hole, the inner wall of the air guide groove or the hole wall of the second air guide hole, thereby greatly reducing the risk of condensation of the aerosol in the microphone, which is beneficial to the normal work of the aerosol generating device.

[0039] Figure 1 is a structural schematic diagram of an aerosol generating device provided by an embodiment of the present application, as shown in the figure, the aerosol generating device includes a power supply assembly 100 and an atomizer 200. The power supply assembly 100 is connected with the atomizer 200, and the power supply assembly 100 is used to supply power to the atomizer 200. Figure 1

[0040] Figure 2 is a schematic diagram of the internal structure of an atomizer provided by an embodiment of the present application, as shown in the figure, the atomizer 200 includes a liquid storage assembly 210 and an atomization assembly 220. The liquid storage assembly 210 is used to store an aerosol substrate. The atomization assembly 220 is located in the liquid storage assembly 210, and the atomization assembly 220 is used to heat the aerosol substrate, and the atomization assembly 220 forms an atomization channel 220a. Figure 2

[0041] The liquid storage assembly 210 can include a liquid tank shell 211, and the inside of the liquid tank shell 211 forms a liquid tank for containing the aerosol substrate. In some examples, the liquid storage assembly 210 can also include a liquid storage member, for example, the liquid storage member can be liquid storage cotton, which is adsorbed / infiltrated with the aerosol substrate.

[0042] The atomization assembly 220 is located in the liquid tank shell 211. The atomization assembly 220 includes a mounting frame 221, a liquid guide member 222 and a heating member 223. The mounting frame 221 forms the atomization channel 220a, and the liquid guide member 222 and the heating member 223 are located in the mounting frame 221. The material and structure of the heating member 223 are not limited, as long as it can play a heating role, for example, the heating member 223 can include at least one of a heating net, a heating film, a heating wire and a heating sheet.

[0043] ​​The mounting rack 221 provides a space inside the liquid cartridge shell 211 to accommodate the liquid guide 222 and the heating element 223. The mounting rack 221 can be tubular, and the tube wall of the mounting rack 221 can have a hole, a gap or the like structure, so that the aerosol substrate in the liquid cartridge shell 211 can enter the atomization channel 220a and be absorbed by the liquid guide 222. The heating element 223 is used to heat the aerosol substrate in the liquid guide 222 to vaporize the aerosol substrate.

[0044] As an example, the liquid cartridge shell 211 can be integrally connected with a suction nozzle 2111, and the suction nozzle 2111 is in communication with the atomization channel 220a. The heated and vaporized aerosol substrate can be discharged outwardly from the suction nozzle 2111. In other examples, the suction nozzle 2111 can also be detachably connected with the liquid cartridge shell 211.

[0045] As an example, the power supply assembly 100 and the atomizer 200 are detachably connected. In other examples, the power supply assembly 100 and the atomizer 200 can also be fixedly connected. For example, the shell part of the power supply assembly 100 and the liquid cartridge shell 211 of the atomizer 200 are an integral structure.

[0046] Figure 3 is a structural schematic diagram of a power supply assembly of an aerosol generating device provided by an embodiment of the present application. As shown in Figure 3 The power supply assembly 100 includes a bracket 101, a first sealing gasket 102 and a second sealing gasket 103.

[0047] The bracket 101 includes an atomizer connecting part 1011 and a microphone mounting part 1012 connected with each other, and the atomizer connecting part 1011 has an atomizer connecting groove 1011a for connecting the atomizer 200. Referring to Figure 1 As shown in, the atomizer 200 can be partially located in the atomizer connecting groove 1011a.

[0048] Figure 4 is a structural schematic diagram of a bracket provided by an embodiment of the present application. As shown in Figure 4 The microphone mounting part 1012 is located at the groove bottom of the atomizer connecting groove 1011a, and the microphone mounting part 1012 has a gas guide groove 1012a extending away from the atomizer connecting groove 1011a.

[0049] Figure 5 is an assembly schematic diagram of a bracket, a first sealing gasket and a second sealing gasket provided by an embodiment of the present application. As shown in Figure 5 The first sealing gasket 102 has a first gas guide hole 102a, and the first sealing gasket 102 is located at one end of the gas guide groove 1012a close to the atomizer connecting groove 1011a. The first gas guide hole 102a communicates the atomizer connecting groove 1011a and the gas guide groove 1012a.

[0050] Figure 6 is an assembly diagram of a support, a first sealing gasket and a second sealing gasket provided by an embodiment of the present application. Figure 5 and Figure 6 opposite sides of the support 101 are shown. As shown in Figure 6 , the second sealing gasket 103 has a microphone accommodating groove 103a and a second air guide hole 103b, and the second sealing gasket 103 is located at one end of the air guide groove 1012a away from the atomizer connecting groove 1011a. The second air guide hole 103b communicates the microphone accommodating groove 103a and the air guide groove 1012a.

[0051] Exemplarily, Figure 7 is a top view of an atomizer connecting part provided by an embodiment of the present application, as shown in Figure 7 , the atomizer connecting groove 1011a has a through hole 1011b at the bottom of the groove, and the first air guide hole 102a penetrates the first sealing gasket 102, one end of the first air guide hole 102a communicates with the through hole 1011b, and the other end communicates with the air guide groove 1012a.

[0052] By setting the atomizer connecting groove 1011a at the atomizer connecting part 1011 of the support 101, the atomizer 200 is connected. By setting the air guide groove 1012a at the microphone mounting part 1012, the air guide groove 1012a extends away from the atomizer connecting groove 1011a, the first sealing gasket 102 is arranged at one end of the air guide groove 1012a, the air guide groove 1012a is communicated with the atomizer connecting groove 1011a through the first air guide hole 102a of the first sealing gasket 102, the second sealing gasket 103 is arranged at the other end of the air guide groove 1012a, the air guide groove 1012a is communicated with the microphone 104 in the microphone accommodating groove 103a through the second air guide hole 103b of the second sealing gasket 103, and the air pressure in the air guide groove 1012a changes during the user inhaling through the mouthpiece 2111. The aerosol generated in the atomizer 200 needs to pass through the first air guide hole 102a, the air guide groove 1012a and the second air guide hole 103b to reach the microphone 104, so the path is relatively long, and the aerosol may condense on the hole wall of the first air guide hole 102a, the inner wall of the air guide groove 1012a or the hole wall of the second air guide hole 103b before reaching the microphone 104, thereby greatly reducing the risk of condensation of the aerosol in the microphone 104, which leads to abnormality of the microphone 104, and facilitating the normal work of the aerosol generating device.

[0053] In some examples, the microphone mounting part 1012 is located at the bottom of the atomizer connecting groove 1011a near one side edge, so as to leave space on one side of the microphone mounting part 1012 to facilitate the arrangement of the microphone 104 and other devices. As an example, Figure 3As shown, the power supply assembly 100 further comprises a circuit board 105 and a microphone 104, the circuit board 105 is located on one side of the microphone mounting portion 1012. The microphone 104 is located in the microphone accommodating groove 103a and connected with the circuit board 105. The second gasket 103 can be sealingly matched with the circuit board 105, so that the microphone 104 can more accurately detect the pressure change in the air guide groove 1012a.

[0054] As shown in the Figure 4 The bracket 101 can further comprise a partition plate 1013 connected to the side of the microphone mounting portion 1012 away from the atomizer connecting portion 1011. The circuit board 105 is located on one side of the partition plate 1013. The power supply assembly 100 can further comprise a battery 106 located on the side of the partition plate 1013 away from the circuit board 105.

[0055] The power supply assembly 100 can further comprise a shell 108 which can be sleeved outside the bracket 101, and a display screen 109 which can be located on the side of the circuit board 105 away from the partition plate 1013. The display screen 109 is electrically connected with the circuit board 105. The display screen 109 can be connected with the shell 108.

[0056] As shown in the Figure 4 The air guide groove 1012a can be arc-shaped.

[0057] The arc-shaped air guide groove 1012a can slow down the airflow speed, which helps the aerosol entering the air guide groove 1012a to condense on the inner wall of the air guide groove 1012a. Moreover, the arc-shaped air guide groove 1012a has a larger inner wall area, which can also increase the contact area with the aerosol, so that more aerosol can condense in the air guide groove 1012a, further reducing the risk of aerosol entering the microphone 104.

[0058] As shown in the Figure 4 The microphone mounting portion 1012 has a first gasket accommodating groove 1012b located at one end of the air guide groove 1012a close to the atomizer connecting groove 1011a. The first gasket 102 is inserted into the first gasket accommodating groove 1012b, and the first gasket 102 is in interference fit with the first gasket accommodating groove 1012b.

[0059] The first gasket accommodating groove 1012b is arranged at the end of the air guide groove 1012a to accommodate the first gasket 102, and the first gasket 102 is in interference fit with the first gasket accommodating groove 1012b, so that the first gasket 102 is firmly installed and avoids loosening.

[0060] In some examples, the first gasket accommodating groove 1012b can penetrate through the microphone mounting portion 1012.

[0061] Since the first gasket accommodating groove 1012b is through, it is easier to clean the aerosol substrate accumulated in the first gasket accommodating groove 1012b after the first gasket 102 is removed.

[0062] Figure 8 is a structural schematic diagram of a first gasket provided by an embodiment of the present application. As shown in Figure 8 As an example, the first gasket 102 can include a gasket body 1021 having a first groove 1021a on a side of the gasket body 1021 close to the atomizer connecting groove 1011a. The first gas guide hole 102a is located at the bottom of the first groove 1021a.

[0063] The first groove 1021a is arranged on the side of the gasket body 1021 close to the atomizer connecting groove 1011a, so that the aerosol passing through the through hole 1011b will first enter the first groove 1021a before entering the first gas guide hole 102a. A portion of the aerosol will condense on the inner wall of the first groove 1021a and adhere to the inner wall of the first groove 1021a, and will not enter the first gas guide hole 102a. By reducing the aerosol entering the first gas guide hole 102a, the risk of aerosol condensation in the microphone 104 is further reduced.

[0064] As shown in Figure 8 The first gasket 102 further includes an elastic ridge 1022 on the surface of the gasket body 1021. The elastic ridge 1022 is arranged at least around the first groove 1021a.

[0065] By arranging the elastic ridge 1022 at least one round around the first groove 1021a, the sealing performance of the first gasket 102 can be improved to avoid aerosol entering the gap between the gasket body 1021 and the side wall of the first gasket accommodating groove 1012b.

[0066] In the present example, the elastic ridge 1022 can also surround the gasket body 1021 one round and abut against the multiple side walls of the first gasket accommodating groove 1012b to avoid aerosol leakage outside the microphone mounting portion 1012.

[0067] The elastic ridge 1022 and the gasket body 1021 can be an integral structure, for example, the first gasket 102 can be an injection molded part, and the elastic ridge 1022 and the gasket body 1021 are integrally injection molded.

[0068] As shown in Figure 4As shown, the microphone mounting portion 1012 has a second gasket receiving groove 1012c located at an end of the air guide groove 1012a away from the atomizer connecting groove 1011a. As shown, Figure 5 As shown, the second gasket 103 is located at one side of the microphone mounting portion 1012, and partially inserted into the second gasket receiving groove 1012c.

[0069] By providing the second gasket receiving groove 1012c to receive a portion of the second gasket 103, the area in the second gasket receiving groove 1012c not filled by the second gasket 103 can store condensed aerosol, which adheres to the inner wall of the second gasket receiving groove 1012c, reducing the risk of condensation of aerosol in the microphone 104.

[0070] As shown, Figure 4 The second gasket receiving groove 1012c extends through the microphone mounting portion 1012.

[0071] Since the second gasket receiving groove 1012c is through, it is easier to clean the accumulated aerosol substrate in the second gasket receiving groove 1012c after removing the second gasket 103.

[0072] The second gasket 103 is partially located outside the second gasket receiving groove 1012c, and the circuit board 105 is located at the side of the second gasket 103 away from the microphone mounting portion 1012, so that the second gasket 103 is in contact with the surface of the circuit board 105 and forms a seal, separating the microphone 104 on the surface of the circuit board 105 from the outside.

[0073] Referring again to Figure 3 The power supply assembly further includes a sealing sheet 107 located at one side of the microphone mounting portion 1012. The sealing sheet 107 is attached to the surface of the microphone mounting portion 1012 to seal at least one of the first gasket receiving groove 1012b, the second gasket receiving groove 1012c, and the air guide groove 1012a.

[0074] In this example, the sealing sheet 107 is attached to the surface of the microphone mounting portion 1012 to seal the first gasket receiving groove 1012b, the second gasket receiving groove 1012c, and the air guide groove 1012a.

[0075] The sealing sheet 107 and the circuit board 105 are located on opposite sides of the microphone mounting portion 1012, and the air guide groove 1012a is located on the side of the microphone mounting portion 1012 close to the sealing sheet 107, and is sealed by the sealing sheet 107. After the aerosol generating device is used for a period of time, the sealing sheet 107 can be removed to clean the air guide groove 1012a to remove the aerosol substrate adhering in the air guide groove 1012a.

[0076] The above-described embodiments are only used to illustrate the technical solutions of the present application, but not limit the present application; although the present application is described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should be included in the protection scope of the present application.
