[0057] Please see Figures 1-2 , Figure 1This is a schematic diagram of the structure of an aerosol generator 100 provided in some embodiments of this application. Figure 2 An exploded schematic diagram of an aerosol generator 100 provided in some embodiments of this application.

[0058] Please see Figure 1 and Figure 2 The aerosol generator 100 provided in this application embodiment includes an inhalation device 20 and a heating device 10, with the heating device 10 disposed at one end of the inhalation device 20.

[0059] Please see Figure 2 A cup body 201 is provided at one end of the inhalation device 20. The cup body 201 is used to hold the aerosol matrix. The heating device 10 is located at the end of the inhalation device 20 where the cup body 201 is provided. The heating device 10 is used to heat the aerosol matrix in the cup body 201.

[0060] Please see Figure 2 The diagram illustrates that the inhalation device 20 includes an inhalation tube 202. When the user inhales through the inhalation tube 202, external airflow can enter the inhalation device 20 through the heating device 10. The aerosol generated by the heating device 10 heating the aerosol matrix can flow into the interior of the inhalation device 20 with the airflow. After being filtered by the liquid inside the inhalation device 20, the aerosol flows to the inhalation tube 202.

[0061] Please see Figures 3-7 , Figure 3 This is a schematic diagram of the structure of the heating device 10 provided in some embodiments of this application. Figure 4 This is a cross-sectional schematic diagram of the heating device 10 provided in some embodiments of this application. Figure 5 This is a cross-sectional schematic diagram of the heating device 10 and the cup body 201 provided in some embodiments of this application. Figure 6 This is an exploded view of the support frame 12 provided in some embodiments of this application. Figure 7 This is a cross-sectional schematic diagram of a support frame 12 provided in some embodiments of this application.

[0062] Please see Figure 4 The heating device 10 provided in this application embodiment includes a main frame 1, a heating component 2, and a power supply structure 3. The heating component 2 and the power supply structure 3 are disposed inside the main frame 1.

[0063] The heating element 2 is electrically connected to the power supply structure 3, that is, the power supply structure 3 can provide power to the heating element 2. When the power supply structure 3 and the heating element 2 form a circuit, the heating element 2 can convert electrical energy into heat energy. At this time, the heating element 2 can heat the air flowing through it. That is, when the user inhales through the inhalation device 20, the external airflow can enter the inhalation device 20 through the heating element 2.

[0064] Please see Figure 4 The main frame 1 has a placement cavity 114, and the power supply structure 3 includes a battery 31, which is disposed in the placement cavity 114. The power supply structure 3 includes at least one battery 31; for example, the power supply structure 3 may include one, two, or three batteries 31.

[0065] In some examples, battery 31 can be set as a rechargeable battery, or it can be set as a non-rechargeable battery.

[0066] In some examples, the heating element 2 can be a heating wire, a heating mesh, or a ceramic plate.

[0067] In the embodiments of this application, please refer to Figure 4 The placement cavity 114 is arranged along the outer periphery of the heating component 2, so as to minimize the impact of the position of the battery 31 on the airflow through the heating component 2.

[0068] In this embodiment, the heating device 10 also includes a power supply structure 3, so that the power supply structure 3 can provide power to the heating component 2, avoiding the problem in the prior art where the heating of the aerosol matrix by the aerosol generator is limited to a place with a power socket; in addition, the placement cavity 114 is set along the outer periphery of the heating component 2 and the battery 31 of the power supply structure 3 is located in the placement cavity 114, so as to avoid the position of the battery 31 in the main frame 1 from affecting the airflow through the heating component 2, thus affecting the heat exchange between the heating component 2 and the airflow.

[0069] In some embodiments, see Figure 4 The main frame 1 includes a first end 13 and a second end 14 arranged opposite to each other. An air inlet 111 and an air outlet 1221 are respectively provided on the first end 13 and the second end 14. The heating component 2 is arranged between the first end 13 and the second end 14.

[0070] Please see Figure 4 The arrows indicate the direction of airflow. When the user inhales through the inhalation device 20, the external airflow can enter the main frame 1 through the air inlet 111, pass through the heating component 2, and be discharged through the air outlet 1221. The air outlet 1221 faces the cup body 201, and the high-temperature air discharged from the air outlet 1221 can heat the aerosol matrix inside the cup body 201.

[0071] In this embodiment, by setting an air inlet 111 and an air outlet 1221 on the first end 13 and the second end 14 respectively, and setting a heating component 2 between the first end 13 and the second end 14, the placement cavity 114 is arranged along the outer circumferential direction of the heating component 2, so as to minimize the impact of the position of the battery 31 in the main frame 1 on the airflow passing through the heating component 2.

[0072] It is worth noting that the above embodiment describes the main frame 1 as including a first end 13 and a second end 14 disposed opposite to each other. The first end 13 and the second end 14 are respectively provided with an air inlet 111 and an air outlet 1221. For other embodiments, please refer to... Figure 4 The main frame 1 may also include an outer peripheral side portion 15, which is located between the first end portion 13 and the second end portion 14. At least an air inlet 111 is provided on the outer peripheral side portion 15, that is, an air inlet 111 may be provided only on the outer peripheral side portion 15, or an air inlet 111 may be provided on both the outer peripheral side portion 15 and the first end portion 13.

[0073] In some embodiments, see Figure 4 and Figure 5 The main frame 1 forms a receiving space 115 for placing the cup 201. The receiving space 115 is located on the side of the second end 14 away from the first end 13. The placement cavity 114 is arranged around the circumference of the receiving space 115. The air vent 1221 is connected to the receiving space 115.

[0074] In this embodiment, the main frame 1 forms a receiving space 115 so that the cup body 201 can be inserted into the receiving space 115, and the heating device 10 is stably supported on the cup body 201.

[0075] In some embodiments, see Figure 4 and Figure 5 A protruding portion 1224 extending into the cup body 201 is formed on the first end 13, and the protruding portion 1224 is located in the middle region of the second end 14.

[0076] Please see Figure 5 The solid arrows indicate the direction of airflow. External airflow enters the main frame 1 through the air inlet 111, passes through the heating component 2, and then exits through the air outlet 1221, flowing towards the cup body 201. The hot air flowing towards the cup body 201 flows into the suction device 20 through the air passage in the middle of the cup body 201. In this embodiment, a protruding portion 1224 is provided on the second end 14 to prevent the airflow from flowing along the dashed arrows and into the air passage in the middle of the cup body 201 after exiting through the air outlet 1221. This would be detrimental to the heating of the aerosol matrix inside the cup body 201 by the high-temperature hot air exiting through the air outlet 1221, thus affecting the heating effect on the aerosol matrix.

[0077] In this embodiment, by providing a protruding portion 1224 extending into the cup body 201 on the second end 14, the flow direction of the hot airflow discharged from the air outlet 1221 can be affected, which facilitates the guidance of the airflow to the aerosol matrix and ensures the heating effect on the aerosol matrix.

[0078] In some embodiments, the number of placement cavities 114 is one; or, there are two or more placement cavities 114, with each placement cavity 114 spaced apart along the circumferential direction of the receiving space 115.

[0079] When there is only one placement cavity 114, the placement cavity 114 can be arranged in a ring shape, for example, the placement cavity 114 can be arranged in a circular ring or a square ring; or, the placement cavity 114 can be arranged in a semi-circular shape along the circumference of the heating device 10, etc.

[0080] When there are two or more placement cavities 114, for example, the number of placement cavities 114 can be set to two, three or four, etc. In some examples, each placement cavity 114 can be equipped with a battery 31, or some placement cavities 114 can be equipped with a battery 31.

[0081] In some embodiments, see Figure 4 The main frame 1 includes a main housing 11 and a support frame 12. The main housing 11 has a mounting cavity 113. The support frame 12 is mounted on the main housing 11 and located in the mounting cavity 113. The heating component 2 is mounted on the support frame 12.

[0082] In some examples, the support frame 12 may be detachably mounted on the main housing 11.

[0083] In some examples, the heating element 2 may be detachably mounted on the support frame 12.

[0084] In this embodiment of the application, the main frame 1 is provided to include a main housing 11 and a support frame 12 to facilitate the assembly of the heating device 10.

[0085] In some embodiments, see Figure 4 The main housing 11 is provided with an opening 112, one end of the support frame 12 is exposed to the outside through the opening 112, one end of the air outlet 1221 is opened to the end face of the support frame 12 exposed outside the opening 112, and the main housing 11 is provided with an air inlet 111.

[0086] Please see Figure 4 The end of the support frame 12 exposed outside the opening 112 is the second end 14 of the main frame 1. In some examples, one end of the support frame 12 may be inserted into the opening 112. Please refer to [link to relevant documentation]. Figure 4 The support frame 12 has a protruding part 1224 on the end face of the end into which it is inserted into the opening 112. The end of the main housing 11 opposite to the opening 112 forms the first end 13 of the main frame 1, and an air inlet 111 is provided on the first end 13.

[0087] In this embodiment of the application, an opening 112 is provided on the main housing 11 so that the air outlet 1221 can be provided on the support frame 12.

[0088] In some embodiments, see Figure 4 The support frame 12 has a receiving cavity 123, the heating element 2 is disposed in the receiving cavity 123, and the support frame 12 has a central air inlet 1211 communicating with the receiving cavity 123, and an air outlet 1221 communicating with the receiving cavity 123. Please refer to Figure 4 External air can enter the mounting cavity 113 through the air inlet 111. The gas in the mounting cavity 113 enters the receiving cavity 123 through the middle air inlet 1211. The air in the receiving cavity 123 is discharged through the air outlet 1221 after passing through the heating component 2.

[0089] In this embodiment, by placing the heating component 2 inside the receiving cavity 123 of the support frame 12, and by ensuring that the air entering the main housing 11 from the air inlet 111 passes through the receiving cavity 123 before being discharged outside the main frame 1, the airflow can fully contact the heating component 2, thereby increasing the temperature of the airflow flowing through the heating device 10 to fully heat the aerosol matrix. In addition, since the heating component 2 is placed inside the receiving cavity 123, the situation where the aerosol matrix easily remains on the heating component 2 when using the aerosol generator 100 can be avoided, thus ensuring the heating effect of the heating component 2.

[0090] In some embodiments, the central air inlet 1211 and the air outlet 1221 are disposed on opposite sides of the heating component 2, and the central air inlet 1211 and the air outlet 1221 are staggered.

[0091] Regarding the misalignment of the intermediate air inlet 1211 and the air outlet 1221, it can be understood that when the intermediate air inlet 1211 is projected onto the cavity wall surface where the air outlet 1221 is located, the intermediate air inlet 1211 does not coincide with the air outlet 1221, nor does it intersect with the air outlet 1221.

[0092] In this embodiment, by setting the intermediate air inlet 1211 and air outlet 1221 to be staggered, the time for airflow to flow in the receiving cavity 123 is increased, so as to facilitate the airflow to fully absorb the heat generated by the heating component 2.

[0093] In some embodiments, the receiving cavity 123 is annular, and there are multiple central air inlets 1211 spaced apart along the circumferential direction of the support frame 12, and multiple air outlets 1221 spaced apart along the circumferential direction of the support frame 12.

[0094] In some embodiments, see Figure 4 The middle air inlet 1211 is directly opposite the air inlet 111 on the main housing 11, so that the airflow flowing in from the air inlet 111 on the main housing 11 can quickly flow to the middle air inlet 1211.

[0095] In some embodiments, see Figure 4 The support frame 12 has an abutment plate 1222 formed on its circumferential side. The abutment plate 1222 is disposed near the second end 14. The abutment plate 1222 and the end of the support frame 12 away from the second end 14 respectively cooperate with the two inner sides opposite to the main housing 11 to limit the position of the support frame 12 on the main housing 11.

[0096] See some examples. Figure 4 The support frame 12 includes a first support portion 121 and a second support portion 122. Please refer to [link / reference]. Figure 6 The second support portion 122 has an annular groove 1223 formed thereon, and the heating component 2 is used to be disposed in the annular groove 1223. The second support portion 122 is disposed at one end of the first support portion 121, and the first support portion 121 covers the annular groove 1223 to form a receiving cavity 123.

[0097] See some examples. Figure 4 A first sealing element 7 is provided at the end of the first support portion 121 that is away from the second support portion 122, so that the first support portion 121 and the inner side of the main housing 11 can be sealed together by the first sealing element 7.

[0098] See some examples. Figure 4 A second sealing element 8 is provided between the second support portion 122 and the main housing 11. The second sealing element 8 achieves a sealing fit between the abutment plate 1222 and the inner side of the main housing 11 and / or a sealing fit between the opening 112 and the second support portion 122. Alternatively, the second sealing element 8 can be configured to only achieve a sealing fit between the abutment plate 1222 and the inner side of the main housing 11, or to only achieve a sealing fit between the opening 112 and the second support portion 122. Alternatively, please refer to [link to relevant documentation]. Figure 4 The second sealing element 8 is provided to achieve a sealing fit between the abutment plate 1222 and the inner side of the main housing 11, as well as a sealing fit between the opening 112 and the second bracket part 122.

[0099] See some examples. Figure 6 and Figure 7 The first support portion 121 includes a cylindrical body 1212 and a circumferential cover plate 1213. The circumferential cover plate 1213 is disposed on the outer circumferential side of the cylindrical body 1212 and near the top of the cylindrical body 1212. The circumferential cover plate 1213 is provided with a central air inlet 1211 and is used to cover the annular groove 1223; please refer to Figure 7The second support portion 122 includes a support bottom 1225, a first annular cylinder 1226, and a second annular cylinder 1227. The first annular cylinder 1226 and the second annular cylinder 1227 are disposed at one end of the support bottom 1225. The first annular cylinder 1226 is fitted inside the second annular cylinder 1227, and an annular groove 1223 is formed between them. An abutment plate 1222 is provided on the outer periphery of the support bottom 1225. A protruding portion 1224 is provided on the side of the support bottom 1225 away from the first annular cylinder 1226 and the second annular cylinder 1227. An air vent 1221 is provided on the support bottom 1225. Please refer to [link / reference]. Figure 6 The cylinder 1212 is inserted into the first annular cylinder 1226.
