[0020] In a third aspect, the embodiments of the present application further provide an aerosol generating device, the aerosol generating device includes an atomizer and the power supply assembly as described in the second aspect, the power supply assembly is connected with the atomizer, and is used for supplying power to the atomizer.

[0021] The technical scheme provided by the embodiments of the present application has at least the following beneficial effects:

[0022] By setting the butt joint groove, the microphone mounting groove and the airflow channel in the support, and by connecting the butt joint groove and the microphone mounting groove through the airflow channel, the butt joint groove is used to connect the atomizer. During the use of the aerosol generating device, the air pressure in the airflow channel can change with the user's suction, and the microphone in the microphone mounting groove can detect the change of the air pressure in the airflow channel. By arranging the switch piece in the airflow channel, the switch piece is used to block the airflow channel, so as to avoid that the aerosol substrate leaked from the atomizer enters the microphone through the airflow channel and affects the normal work of the microphone. Since the air pressure on the side of the switch piece close to the butt joint groove is lower than the air pressure on the side of the switch piece close to the microphone mounting groove, the switch piece can be opened to make the airflow channel conductive, so the switch piece can be opened during the user's suction, and the airflow channel remains unobstructed, which does not affect the microphone to detect the air pressure in the airflow channel. It can be seen that the arrangement of the switch piece not only does not affect the normal work of the microphone, but also avoids that the aerosol substrate enters the microphone through the airflow channel.

[0048] Figure 1 is a structural schematic diagram of an aerosol generating device provided by an embodiment of the present application, as shown in Figure 1As shown, the aerosol-generating device includes a power supply assembly 100 and an atomizer 200. The power supply assembly 100 is configured to supply power to the atomizer 200.

[0049] Figure 2 is a schematic diagram of an internal structure of an aerosol-generating device provided by an embodiment of the present application. As shown, the atomizer 200 includes a liquid storage assembly 210 and an atomization assembly 220. The liquid storage assembly 210 is configured to store an aerosol substrate. The atomization assembly 220 is located in the liquid storage assembly 210, and the atomization assembly 220 is configured to heat the aerosol substrate, and the atomization assembly 220 forms an atomization channel 220a. Figure 2

[0050] The liquid storage assembly 210 can include a liquid tank housing 211, and an interior of the liquid tank housing 211 forms a liquid tank configured to contain the aerosol substrate. The liquid storage assembly 210 can further include a base 212, which can be fixedly connected or detachably connected to the liquid tank housing 211. The base 212 can be configured to mount an electrode to electrically connect with the power supply assembly 100.

[0051] In some examples, the liquid storage assembly 210 can further include a liquid storage member, for example, the liquid storage member can be liquid storage cotton, which is adsorbed / imbibed with the aerosol substrate.

[0052] The atomization assembly 220 is located in the liquid tank housing 211. The atomization assembly 220 includes a support cylinder 221, a liquid guide member 222, a heating member 223, and a pin 224. The support cylinder 221 forms the atomization channel 220a, and the liquid guide member 222 and the heating member 223 are located in the support cylinder 221. The pin 224 is electrically connected with the heating member 223.

[0053] The support cylinder 221 provides a space in an interior of the liquid tank housing 211 to accommodate the liquid guide member 222 and the heating member 223. The support cylinder 221 can have holes, slits, or other structures on a tube wall thereof, so that the aerosol substrate in the liquid tank housing 211 can enter the atomization channel 220a and be absorbed by the liquid guide member 222. The heating member 223 is configured to heat the aerosol substrate in the liquid guide member 222 to vaporize the aerosol substrate.

[0054] The material and structure of the heating member 223 are not limited as long as the heating member 223 can generate heat. For example, the heating member 223 can include at least one of a heating mesh, a heating film, a heating wire, and a heating sheet.

[0055] The pin 224 is located at an end of the support cylinder 221 outside the liquid tank housing 211 and penetrates through the base 212 to contact the electrode mounted on the base 212.

[0056] ​The power supply assembly 100 includes a bracket 101, a battery 104, a circuit board 103, and a microphone 102. The bracket 101 is connected to the atomizer 200, and the battery 104 is located on the side of the bracket 101 away from the atomizer 200. The circuit board 103 is located between the battery 104 and the bracket 101. The microphone 102 is located on the side of the circuit board 103 closer to the bracket 101. The bracket 101 also has a microphone port 1011c, and the microphone 102 is positioned opposite the microphone port 1011c. The microphone 102 controls the operation of the atomization assembly 220 by detecting changes in air pressure.

[0057] Figure 3 This is a partial structural schematic diagram of a power supply component provided in an embodiment of this application. For example... Figure 3 As shown, in this example, the bracket 101 has a battery compartment in the middle, and the battery 104 is located in the battery compartment. The circuit board 103 and the microphone 102 can be located outside the battery compartment and on the side of the battery 104 away from the atomizer 200. The microphone 102 is directly opposite the microphone hole 1011c of the bracket 101. Figure 3 The arrows in the diagram schematically indicate the airflow direction in the power supply assembly 100 during the suction process.

[0058] During the use of the aerosol generating device, aerosol leakage may occur in the atomizer 200. The leaked aerosol matrix can easily enter the microphone hole 1011c and then the microphone 102, thereby affecting the normal operation of the microphone 102.

[0059] Figure 4 This is a schematic diagram of the structure of a power supply component bracket provided in an embodiment of this application, as shown below. Figure 4 As shown, the bracket includes a docking part 1011 and a switch part 107. Figure 5 yes Figure 4 Section I-I, as shown Figure 5 As shown, the docking part 1011 has a docking groove 1011a, a microphone mounting groove 1011b and an airflow channel 1011d. The docking groove 1011a is used to connect with the atomizer 200, and the airflow channel 1011d connects the docking groove 1011a and the microphone mounting groove 1011b.

[0060] The switch 107 is located in the airflow channel 1011d, which blocks the airflow channel 1011d. The switch 107 is configured such that if the air pressure on the side of the switch 107 near the docking groove 1011a is lower than the air pressure on the side of the switch 107 near the microphone mounting groove 1011b in the extending direction of the airflow channel 1011d, the switch 107 is opened, so that the airflow channel 1011d is open.

[0061] The airflow passage 1011d includes an upstream portion and a downstream portion in the extension direction of the airflow passage 1011d, the upstream portion and the downstream portion being delimited by the switch piece 107, the upstream portion referring to a section of the airflow passage 1011d close to the docking groove 1011a, and the downstream portion referring to a section of the airflow passage 1011d close to the microphone mounting groove 1011b. In the extension direction of the airflow passage 1011d, the air pressure on the side of the switch piece 107 close to the docking groove 1011a is lower than the air pressure on the side of the switch piece 107 close to the microphone mounting groove 1011b, that is, the air pressure of the upstream portion is lower than the air pressure of the downstream portion.

[0062] By providing the docking groove 1011a, the microphone mounting groove 1011b and the airflow passage 1011d on the docking portion 1011 of the support 101, and by connecting the docking groove 1011a and the microphone mounting groove 1011b through the airflow passage 1011d, the docking groove 1011a is used to connect the atomizer 200. During the use of the aerosol generating device by the user, the air pressure in the airflow passage 1011d can change with the suction of the user, and the microphone 102 located in the microphone mounting groove 1011b can detect the change of the air pressure in the airflow passage 1011d. By arranging the switch piece 107 in the airflow passage 1011d, the switch piece 107 is used to block the airflow passage 1011d, so as to avoid the aerosol substrate leaked from the atomizer 200 entering the microphone 102 through the airflow passage 1011d and affecting the normal work of the microphone 102. Since the air pressure on the side of the switch piece 107 close to the docking groove 1011a is lower than the air pressure on the side of the switch piece 107 close to the microphone mounting groove 1011b, the switch piece 107 can be opened to make the airflow passage 1011d conductive, so the switch piece 107 can be opened during the suction of the user, and the airflow passage 1011d remains unobstructed, which does not affect the microphone 102 to detect the air pressure in the airflow passage 1011d. It can be seen that the arrangement of the switch piece 107 not only does not affect the normal work of the microphone 102, but also avoids the aerosol substrate entering the microphone 102 through the airflow passage 1011d.

[0063] Figure 6 is a structural schematic diagram of a switch piece provided by an embodiment of the present application, as shown in Figure 6 The switch piece 107 includes a fixed portion 1071 and an elastic diaphragm 1072, and the fixed portion 1071 is connected with the docking portion 1011. The fixed portion 1071 has a first through hole 1071a, the elastic diaphragm 1072 is located in the first through hole 1071a, and the edge of the elastic diaphragm 1072 is connected with the hole wall of the first through hole 1071a. The elastic diaphragm 1072 deforms based on the air pressure difference on both sides of the elastic diaphragm 1072, so as to make the first through hole 1071a conductive.

[0064] During the user's puffing, the two ends of the first through hole 1071a will generate a pressure difference, along the airflow channel 1011d, the air pressure at the end of the first through hole 1071a away from the microphone 102 will decrease, which is less than the air pressure at the end of the first through hole 1071a close to the microphone 102, so that there is a pressure difference between the two ends of the first through hole 1071a. The elastic diaphragm 1072 has a certain elasticity and can deform to the side with lower air pressure under the action of the pressure difference, so that the airflow can flow from the end with lower air pressure to the end with higher air pressure in the first through hole 1071a. During the user's stopping of puffing, the air pressure at the two ends of the first through hole 1071a is equal, and the elastic diaphragm 1072 restores under the action of its own elasticity, blocking the first through hole 1071a, thereby avoiding the aerosol substrate passing through the first through hole 1071a, and thus avoiding the aerosol substrate entering the microphone 102.

[0065] As shown in Figure 6 , the elastic diaphragm 1072 can have a plurality of slits 1072a. The plurality of slits 1072a intersect with each other, and the plurality of slits 1072a are symmetric about the center of the intersection.

[0066] The plurality of slits 1072a divide the elastic diaphragm 1072 into a plurality of valves. Figure 7 is a local structure schematic diagram of a switch piece provided by an embodiment of the present application, Figure 7 , which shows the state of the switch piece 107 being opened. As shown in Figure 7 , when there is a pressure difference between the two ends of the first through hole 1071a, each valve will bend to the side with lower air pressure, and the plurality of valves will separate from each other, so that the airflow can smoothly pass through the switch piece 107. When the air pressure at the two ends of the first through hole 1071a is equal, the valves will flatten under the action of elasticity, and the valves will close to each other, blocking the first through hole 1071a.

[0067] As an example, in an embodiment of the present application, the elastic diaphragm 1072 has two slits 1072a, and the two slits 1072a are perpendicular to each other, and the two slits 1072a divide the elastic diaphragm 1072 into four valves.

[0068] In other possible implementations, the elastic diaphragm 1072 can also have only one slit 1072a. Since there is only one slit 1072a, the elastic diaphragm 1072 is only divided into two valves, so that during the user's stopping of puffing, the two valves can close more tightly, reducing the risk of aerosol substrate leaking into the microphone 102.

[0069] Figure 8 is a structure schematic diagram of another switch piece provided by an embodiment of the present application, as Figure 8As shown, in this example, part of the edge of the elastic diaphragm 1072 is separated from the hole wall of the first through hole 1071a, and a gap 1072b is formed.

[0070] That is, part of the edge of the elastic diaphragm 1072 is connected to the hole wall of the first through hole 1071a, and another part of the edge is not connected to the hole wall of the first through hole 1071a. When there is a pressure difference between the two ends of the first through hole 1071a, the part of the elastic diaphragm 1072 not connected to the hole wall of the first through hole 1071a will fold to the side with lower air pressure, thereby making the first through hole 1071a conductive, and the airflow can pass normally. When the air pressure at both ends of the first through hole 1071a is equal, the folded part of the elastic diaphragm 1072 can recover and reseal the first through hole 1071a.

[0071] The fixed part 1071 serves to fix the elastic diaphragm 1072. The shape and structure of the fixed part 1071 can be set according to the shape and structure of the docking part 1011, and the switch piece 107 can be stably fixed to the docking part 1011, so that the elastic diaphragm 1072 can work normally.

[0072] As an example, the switch piece 107 can be detachably connected to the docking part 1011.

[0073] After the aerosol generating device is used for a relatively long time, the elasticity of the elastic diaphragm 1072 may decrease, and even without suction, the adjacent valves are difficult to completely close, there is a large gap, and the ability to isolate the aerosol substrate is weakened. By replacing the switch piece 107, the service life of the aerosol generating device can be extended.

[0074] In other examples, the switch piece 107 can also be fixedly connected to the docking part 1011. For example, the bracket can be made of double-color plastic molding process, and the switch piece 107 and the docking part 1011 are made of different materials. By using a fixed connection, the switch piece 107 and the docking part 1011 are more tightly connected and are not easy to come off, and the connection between the switch piece 107 and the docking part 1011 is also more airtight, and is not easy to leak air or aerosol substrate.

[0075] The switch piece 107 can be flexibly arranged at multiple positions in the airflow passage 1011d, as long as it can block the airflow passage 1011d and control the conduction of the airflow passage 1011d.

[0076] As an example, referring to Figure 4 and Figure 5 , the airflow passage 1011d includes a microphone hole 1011c, and the switch piece 107 is located in the microphone hole 1011c.

[0077] In this example, the microphone mounting slot 1011b is located at the bottom of the docking slot 1011a, and the microphone hole 1011c penetrates the bottom of the docking slot 1011a, connecting the microphone mounting slot 1011b and the docking slot 1011a. The switch 107 is directly placed in the microphone hole 1011c, obscuring the microphone 102. Utilizing the existing microphone hole 1011c minimizes the impact on the bracket structure, facilitating design based on existing brackets and reducing design costs.

[0078] Figure 9 This is a schematic diagram of another support structure provided in an embodiment of this application, as shown below. Figure 9 As shown, in this example, the airflow channel 1011d includes a microphone hole 1011c and an air guide groove 1011e. The air guide groove 1011e connects the microphone hole 1011c and the docking groove 1011a. The switching element 107 is located in the air guide groove 1011e.

[0079] The position of the microphone orifice 1011c usually varies depending on the bracket. For brackets where the microphone orifice 1011c is located outside the bottom of the docking groove 1011a, the microphone orifice 1011c and the docking groove 1011a can be connected through the air guide groove 1011e, allowing for pressure changes at the microphone orifice 1011c during user suction. Placing the switch 107 in the air guide groove 1011e provides greater flexibility in arrangement and placement.

[0080] In some examples, the switch 107 can be located at one end of the air guide channel 1011e near the docking groove 1011a, which can prevent the air guide channel 1011e from being blocked and affecting the normal air flow in the air guide channel 1011e in the event of leakage of the aerosol matrix.

[0081] Figure 10 This is a schematic diagram of another support structure provided in an embodiment of this application, as shown below. Figure 10 As shown, in this example, the mating part 1011 has a groove 1011f, which is located outside the mating groove 1011a and at the bottom of the mating groove 1011a. Figure 11 This is an assembly diagram of the switch and the air guide channel, such as... Figure 11 As shown, the air guide groove 1011e is located in the groove 1011f, and the switch 107 is located in the air guide groove 1011e.

[0082] Figure 12 This is a schematic diagram of the structure of a bracket provided in an embodiment of this application. Figure 12 At least part of the structure of the docking section 1011 has been removed to facilitate the display of the air guide groove 1011e. For example... Figure 12As shown, the microphone mounting groove 1011b is located on the outer side wall of the recess 1011f. The microphone hole 1011c is located on the side wall of the recess 1011f, and communicates the microphone mounting groove 1011b and the air guide groove 1011e. The air guide groove 1011e communicates with the docking groove 1011a through the second through hole 1011g, that is, the airflow passage 1011d also includes the second through hole 1011g. Figure 12 The direction of the airflow during the suction process is schematically shown by an arrow.

[0083] Compared with directly arranging the microphone mounting groove 1011b on the groove bottom of the docking groove 1011a, arranging the microphone mounting groove 1011b on the side wall of the recess 1011f can reduce the risk of the aerosol substrate leaking directly into the microphone mounting groove 1011b even without the switch piece 107.

[0084] One side of the recess 1011f can be connected with a sealing cover 108, and the sealing cover 108 is detachably connected with the docking portion 1011. The air guide groove 1011e is arranged in the recess 1011f. When the support is manufactured, the air guide groove 1011e can be manufactured in the recess 1011f, and then the sealing cover 108 is connected to the docking portion 1011, and the recess 1011f and the air guide groove 1011e are sealed by the sealing cover 108.

[0085] Exemplarily, the sealing cover 108 can be made of rubber.

[0086] As shown, Figure 12 The support 101 further includes a support plate 1013 and a clamping portion 10131. The support plate 1013 is flush with the outer side wall of the recess 1011f having the microphone mounting groove 1011b, and is connected with the outer side wall of the recess 1011f. The clamping portion 10131 is located on the outer side wall of the recess 1011f having the microphone mounting groove 1011b and the support plate 1013. The clamping portion 10131 is used for clamping the circuit board 103.

[0087] As an example, the clamping portion 10131 can include a plurality of clamping hooks, and the plurality of clamping hooks can be respectively arranged along the edges of the support plate 1013.

[0088] By arranging the support plate 1013, the circuit board 103 with a relatively large installation area can be conveniently installed, and the circuit board 103 can be more stable. By arranging the clamping portion 10131 on the outer side wall of the recess 1011f and one side of the support plate 1013, the circuit board 103 of the aerosol generating device can be fixed, and the loosening of the circuit board 103 can be avoided.

[0089] Figure 13 is a structural schematic diagram of a power supply assembly provided by an embodiment of the present application, as Figure 13 As shown, the power supply assembly 100 includes a circuit board 103, a microphone 102, and aFigures 4-12 Any one of the shown support 101. Circuit board 103 is located on one side of the support 101, the microphone 102 is located in the microphone mounting slot 1011b, the microphone 102 is connected with the circuit board 103.

[0090] The user in the process of using the aerosol generating device, the air pressure in the airflow passage 1011d can change with the user's suction, the microphone 102 located in the microphone mounting slot 1011b can detect the change of air pressure in the airflow passage 1011d. By arranging the switch piece 107 in the airflow passage 1011d, the switch piece 107 is used to cut off the airflow passage 1011d, so that when the atomizer 200 connected in the docking slot 1011a leaks aerosol substrate, the leaked aerosol substrate is difficult to enter the microphone 102 through the airflow passage 1011d, affecting the normal work of the microphone 102. Again, when the air pressure on the side of the switch piece 107 close to the docking slot 1011a is lower than the air pressure on the side of the switch piece 107 close to the microphone mounting slot 1011b, the switch piece 107 can be opened, so that the airflow passage 1011d is conducted. Therefore, the switch piece 107 can be opened during the user's suction, and the airflow passage 1011d remains unobstructed, which does not affect the microphone 102 to detect the air pressure in the airflow passage 1011d.

[0091] As shown in the figure, the power supply assembly 100 further includes a display panel 105, the display panel 105 is located on the side of the circuit board 103 away from the microphone 102, and the display panel 105 is electrically connected with the circuit board 103. Figure 13

[0092] The display panel 105 is arranged on one side of the circuit board 103, so that the display panel 105 and the circuit board 103 are arranged in parallel or approximately parallel, saving space and making the structure of the power supply assembly more compact.

[0093] As shown in the figure, the power supply assembly further includes a battery 104, and the battery 104 is located at the bottom of the docking portion 1011. Figure 13

[0094] Figure 14 It is an internal structure schematic diagram of an aerosol generating device provided by the embodiment of the present application. As shown in the figure, the aerosol generating device includes an atomizer 200 and a power supply assembly 100. The power supply assembly 100 is connected with the atomizer 200. The power supply assembly 100 is used to supply power to the atomizer 200. Figure 14

[0095] In some examples, the power supply assembly 100 is detachably connected with the atomizer 200. Since the power supply assembly 100 is detachably connected with the atomizer 200, the atomizer 200 can be replaced conveniently.

[0096] ​​​In other examples, the power supply assembly 100 and the atomizer 200 may be fixedly connected. For example, the housing portion of the power supply assembly 100 and the liquid tank housing 211 of the atomizer 200 are integrally formed.

[0097] Exemplarily, the power supply assembly 100 may include a first housing 106, within which a bracket 101 is located. The first housing 106 may be snapped into the liquid tank housing 211. The aerosol generating device may include a second housing 301 and an end cap 302, the end cap 302 being connected to the second housing 301 to form a receiving cavity in which both the power supply assembly 100 and the atomizer 200 are located. The second housing 301 may be connected to a nozzle 3011. For example, the second housing 301 and the nozzle 3011 may be an integral structure; or, for example, the second housing 301 and the nozzle 3011 may be detachably connected to facilitate replacement of the nozzle 3011.

[0098] like Figure 14 As shown, the circuit board 103 is located on one side of the bracket 101, and the microphone 102 is located in the microphone mounting slot 1011b. The microphone 102 is connected to the circuit board 103.

[0099] The atomizer 200 includes an atomizing assembly, which includes a connector 226 and an adsorption element 228. The connector 226 is located in a docking groove 1011a. A sealed cavity 200c is formed between the connector 226 and the bottom of the docking groove 1011a. The adsorption element 228 is located in the sealed cavity 200c and is used to absorb aerosol matrix that leaks into the sealed cavity 200c.

[0100] An atomizing chamber 200a is formed between the adsorption element 228 and the connecting seat 226. The opening of the airflow channel 1011d at the end away from the microphone 102 is located at the bottom of the docking groove 1011a, and the airflow channel 1011d is connected to the atomizing chamber 200a.

[0101] For example, the absorbent element 228 can be absorbent cotton.

[0102] like Figure 14 As shown, the connector 226 also has an exhaust channel 226a, one end of which is connected to the atomizing chamber 200a, and the other end is used to connect to the nozzle 3011. During the suction process, air enters the atomizing chamber 200a from the airflow channel 1011d. Figure 14 The arrows in the diagram illustrate the direction of airflow during the suction process.

[0103] like Figure 14As shown, the connector 226 also has a liquid inlet channel 226b, which connects the atomizing chamber 200a and the side of the connector 226 away from the bottom of the docking groove 1011a. The atomizing assembly also includes an atomizing core 227, which is located in the atomizing chamber 200a and separates the liquid inlet channel 226b from the airflow channel 1011d.

[0104] The aerosol matrix can flow to the atomizing core 227 through the liquid inlet channel 226b, keeping the atomizing core 227 in a moist state. When the atomizing core 227 is working, it heats the aerosol matrix, releasing aerosol into the atomization chamber 200a. During suction, the aerosol in the atomization chamber 200a enters the nozzle 3011 through the exhaust channel 226a. The atomizing core 227 separates the liquid inlet channel 226b and the airflow channel 1011d, preventing the aerosol matrix in the liquid inlet channel 226b from flowing into the airflow channel 1011d.

[0105] like Figure 14 As shown, the atomizing core 227 includes a liquid guiding component 222 and a heating component 223, with the heating component 223 located on the side of the liquid guiding component 222 away from the liquid inlet channel 226b. The atomizing assembly also includes an electrode 2231, which is inserted into the bottom of the docking groove 1011a. One end of the electrode 2231 is located in the atomizing chamber 200a and abuts against the heating component 223. The other end of the electrode 2231 is used to connect to the battery 104.

[0106] The liquid guiding element 222 absorbs the aerosol matrix flowing out from the liquid inlet channel 226b and temporarily stores it, keeping the liquid guiding element 222 in a moist state. The heating element 223 heats the liquid guiding element 222, atomizing the aerosol matrix in the liquid guiding element 222 to form an aerosol. By arranging the heating element 223 on the side of the liquid guiding element 222 away from the liquid inlet channel 226b, and with the electrode 2231 abutting against the side of the heating element 223 away from the liquid guiding element 222, the atomizing core 227 can be reinforced, making the atomizing core 227 installed stably, separating the liquid inlet channel 226b and the airflow channel 1011d, and preventing the aerosol matrix in the liquid inlet channel 226b from directly leaking into the atomizing chamber 200a.

[0107] Reference Figure 14 As shown, the atomizer 200 of the aerosol generating device may also include a second seal 229. The second seal 229 is located on the side of the connecting seat 226 away from the adsorption member 228. The second seal 229 forms a seal with the inner wall of the liquid tank housing 211 to improve the sealing performance of the liquid tank.

[0108] Figure 14 The structure of the atomizer 200 in the aerosol generating device shown is only an example; in other possible implementations, the structure of the atomizer 200 in the aerosol generating device may also be the same.Figure 2 The structure of the atomizer 200 shown in the middle is the same.
