[0043] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0044] like Figure 10 and Figure 12 As shown, in order to solve the problem of low assembly efficiency between the oil cup 1 and the body 2 on the existing aerosol generator 100, this application proposes an aerosol generator 100, which mainly includes an oil cup 1 and a body 2.

[0045] Among them, such as Figure 10 and Figure 12As shown, the body 2 is equipped with an atomizer 22, a support assembly 23, and a power supply assembly (not shown in the figure). The atomizer 22 is fixed to the support assembly 23. The atomizer 22 is provided with an airflow channel 223 and an atomizing component 224. The airflow channel 223 has an air inlet and an air outlet that communicate with the outside. The atomizing component 224 is installed in the airflow channel 223. The atomizing component 224 may include a heating element 2241, an inner cotton 2242, an outer cotton 2243, an electrical wire (not shown in the figure), etc. The heating element 2241 is electrically connected to the power supply assembly through the electrical wire so that the heating element 2241 can be energized and generate heat. The inner cotton 2242 is fitted around the heating element 2241, and the outer cotton 2243 is fitted around the inner cotton 2242. The outer cotton 2243 is used to absorb the atomizing liquid from the oil cup 1 and conduct the atomizing liquid to the inner cotton 2242, so that the heating element 2241 can atomize the atomizing liquid on the inner cotton 2242 into an aerosol.

[0046] During suction, air from outside the body 2 can flow into the airflow channel 223 through the air inlet. At the same time, the heating element 2241 atomizes the atomizing liquid into an aerosol. The air flows along the airflow channel 223 to the heating element 2241 and mixes with the aerosol. Then it continues to flow along the airflow channel 223 to the air outlet and finally flows out from the air outlet and into the user's mouth.

[0047] As described above, the oil cup 1 is mainly used to provide atomizing liquid to the atomizer 22. The oil cup 1 may include an outer shell 12 and a sealing member 13. The outer shell 12 is provided with a first liquid storage chamber for storing atomizing liquid. The first liquid storage chamber has an outlet 1211. The atomizing liquid in the first liquid storage chamber can flow through the outlet 1211 to the inlet 222 of the atomizer 22, so that the outer cotton 2243 inside the atomizer 22 can absorb the atomizing liquid into the inner cotton 2242 and the heating element 2241 through the inlet 222. In this embodiment, the shape of the oil inlet is not limited. The oil inlet can be an opening with a specific shape or a gap for liquid flow.

[0048] Crucially, in this application, such as Figures 1 to 5As shown, the oil cup 1 also includes a sealing component 13, which is movably installed in the first liquid storage chamber 121 to open or close the liquid outlet 1211. The body 2 also includes a top pressure component 231. Specifically, when the oil cup 1 and the body 2 are not assembled together, the atomizing liquid is located in the first liquid storage chamber 121. The sealing member 13 blocks the liquid outlet 1211, preventing the atomizing liquid from flowing out of the first liquid storage chamber 121 through the liquid outlet 1211. The sealing member 13 can reduce the phenomenon of oil leakage in the oil cup 1 during transportation and storage. When the oil cup 1 and the body 2 need to be assembled together for use, the oil cup 1 can be directly inserted into the body 2. As the oil cup 1 moves closer to the body 2, the pressing member 231 presses against the sealing member 13 and drives the sealing member 13 to move, so that the sealing member 13 opens the liquid outlet 1211. The liquid outlet 1211 connects the first liquid storage chamber 121 and the liquid inlet 222 of the atomizer 22, and the first liquid storage chamber 121 can supply oil to the atomizer 22. When the user fixes the oil cup 1 to the body 2, the first liquid storage chamber 121 and the liquid inlet 222 of the atomizer 22 are connected. After the oil cup 1 and the body 2 are assembled together, there is no need to open the liquid outlet 1211 through other operation steps, which can simplify the installation steps and improve the assembly efficiency and ease of use of the product.

[0049] Specifically, the shape of the sealing element 13 is not limited; it can be annular, sheet-like, or spherical. The movement of the sealing element 13 is also not limited. For example, as the oil cup 1 moves closer to the body 2, the pressure member 231 can press against the sealing element 13 and cause it to slide axially along the central axis of the body 2, so that the sealing element 13 leaves the liquid outlet 1211, opening the outlet 1211 and allowing the first liquid storage chamber 121 to supply oil to the atomizer 22.

[0050] For example, in an embodiment not shown, the sealing member 13 has a body and a sealing part connected to each other, with a folded edge between the body and the sealing part. The sealing part is used to block the liquid outlet 1211. The pressing member 231 can press against the sealing part and drive the sealing part to rotate around the folded edge so that the sealing part leaves the liquid outlet 1211, the liquid outlet 1211 is opened, and the first liquid storage chamber 121 can supply oil to the atomizer 22.

[0051] Optionally, in one embodiment, such as Figure 3 and Figure 4As shown, the oil cup 1 also includes an inner shell 14, which is disposed within the outer shell 12. A first liquid storage chamber 121 is formed between the inner shell 14 and the outer shell 12. In this embodiment, the installation position of the sealing member 13 is not limited; the sealing member 13 can be fixed to the inner shell 14 or the outer shell 12. The sealing member 13 can move between a first position and a second position. When the sealing member 13 is in the first position, it makes sealing contact with both the inner shell 14 and the outer shell 12 to block the liquid outlet 1211. When the sealing member 13 is in the second position, it separates from either the outer shell 12 or the inner shell 14 to open the liquid outlet 1211. The pressing member 231 can drive the sealing member 13 to move from the first position to the second position.

[0052] Optionally, in one embodiment, such as Figure 3 and Figure 4 As shown, the inner housing 14 has a first end 141 and a second end 142 that are arranged opposite to each other. When the oil cup 1 is installed on the body 2, the first end 141 is located on the side of the inner housing 14 close to the top pressure member 231, and the second end 142 is located on the side of the inner housing 14 away from the top pressure member 231. The first end 141 and the outer housing 12 are spaced apart to form an outlet 1211 for the atomized liquid to flow out.

[0053] In this embodiment, the sealing member 13 is made of silicone material and is sleeved on the outer periphery of the inner shell 14. Specifically, the sealing member 13 is sleeved on the first end 141 of the inner shell 14. The sealing member 13 can move relative to the inner shell 14 along the axial direction of the inner shell 14. When the oil cup 1 is installed on the machine body 2, the pressing member 231 can drive the sealing member 13 to move from the first position to the second position as it approaches the oil cup 1. When the sealing member 13 is in the first position, the sealing member 13 is located between the inner shell 14 and the outer shell 12, and the sealing member 13 is pressed and contacted with the inner shell 14 and the outer shell 12 respectively to seal the liquid outlet 1211; when the oil cup 1 is installed on the body 2, the sealing member 13 is in the second position. At this time, the sealing member 13 is separated from the outer shell 12 and spaced apart from the outer shell 12 to expose at least part of the liquid outlet 1211. The liquid outlet 1211 is opened, and the first liquid storage chamber 121 can supply oil to the atomizer 22.

[0054] Optionally, in one embodiment, such as Figure 3 and Figure 4As shown, the oil cup 1 also includes a sealing element 15, which is installed on the second end 142. The sealing element 15 can seal the gap between the second end 142 and the outer casing 12. Specifically, the outer casing 12 has a bottom wall 124 and a first side wall 122 connected in sequence. The first side wall 122 is spaced apart from the inner casing 14 to form a first liquid storage cavity 121. The second end 142 is adjacent to the bottom wall 124, and an installation gap is formed between the second end 142, the bottom wall 124, and the first side wall 122. The sealing element 15 is provided on the second end 142. The sealing element 15 can make sealing contact with the outer wall surface of the second end 142, the inner wall surface of the first side wall 122, and the inner wall surface of the bottom wall 124, respectively, to seal the installation gap between the second end 142 and the outer casing 12. The sealing element 15 can further improve the sealing performance of the oil cup 1 and reduce the risk of oil leakage. Understandably, when the plugging component 13 is in the first position, the first side wall 122, the inner shell 14, the plugging component 13 and the sealing component 15 together form a sealed first liquid storage cavity 121.

[0055] Optionally, in one embodiment, such as Figure 1 As shown, the sealing element 13 has a ring structure and is sleeved on the outer periphery of the inner shell 14. The sealing element 13 can move axially along the central axis of the inner shell 14. The inner shell 14 can provide guidance and radial limiting for the sealing element 13, making the movement of the sealing element 13 more stable.

[0056] In addition, such as Figure 3 and Figure 4 As shown, a limiting protrusion 143 is also provided on the outer wall surface of the inner shell 14. The sealing member 13 is located on the side of the limiting protrusion 143 away from the second end 142. During the process of the sealing member 13 moving from the first position to the second position, the sealing member 13 gradually moves towards the limiting protrusion 143 and gradually exposes the liquid outlet 1211. When the sealing member 13 abuts against the limiting protrusion 143, the limiting protrusion 143 can restrict the movement of the sealing member 13 and stop the sealing member 13 from moving. At this time, the area of ​​the liquid outlet 1211 is the largest. In this embodiment, the connection method between the limiting protrusion 143 and the inner shell 14 is not limited. The limiting protrusion 143 can be fixed to the inner shell 14 by snap-fit ​​connection, screw connection, welding, bonding or integral molding connection, etc.

[0057] Specifically, during production, the exact position of the limiting protrusion 143 on the inner shell 14 can be determined through calculation, testing, and other methods, thereby controlling the movement stroke of the sealing component 13 and the size of the outlet 1211 area.

[0058] Optionally, in one embodiment, such as Figures 3 to 5As shown, the oil cup 1 is also provided with a second liquid storage chamber 16. When the oil cup 1 is installed on the body 2, the second liquid storage chamber 16 is located on the side of the oil cup 1 near the top pressure member 231. The second liquid storage chamber 16 is connected to the first liquid storage chamber 121 through the liquid outlet 1211. The inner shell 14 is provided with an installation cavity 144 that is connected to the second liquid storage chamber 16. The end of the installation cavity 144 near the liquid outlet 1211 is provided with an insertion port. The atomizer 22 is inserted into the installation cavity 144 through the insertion port, and the liquid inlet 222 is located in the second liquid storage chamber 16.

[0059] Specifically, when the oil cup 1 is installed on the upper side of the body 2, the second position of the sealing part 13 opens the outlet 1211. The atomized liquid in the first liquid storage chamber 121 flows into the second liquid storage chamber 16 under the action of gravity through the outlet 1211. The atomized liquid in the second liquid storage chamber 16 then flows into the atomizer 22 through the inlet hole 222.

[0060] In addition, the inner diameter of the second liquid storage chamber 16 is smaller than that of the first liquid storage chamber 121, which can ensure that the atomizing liquid in the oil cup 1 can be more concentrated in the second liquid storage chamber 16, and the atomizing liquid can be utilized more effectively, reducing waste.

[0061] Optionally, in one embodiment, such as Figures 6 to 10 As shown, the atomizer 22 includes an outer cover 221, which provides protection and installation space for the atomizer 22. The airflow channel 223 and the atomizing component 224 are both located in the outer cover 221, and the liquid inlet 222 is located on the outer cover 221. The bracket assembly 23 of the body 2 also includes a fixing frame 232. The outer cover 221 and the top pressure component 231 are both fixed on the fixing frame 232. The fixing frame 232 provides support for the atomizer 22 and the top pressure component 231. The top pressure component 231 is located on the outer periphery of the outer cover 221 and is spaced apart from the liquid inlet 222, which ensures that the liquid inlet 222 is not blocked by the top pressure component 231 and ensures the unobstructed flow of the liquid inlet 222.

[0062] Optionally, in one embodiment, such as Figures 6 to 8 As shown, the bracket assembly 23 also includes a positioning member 233, which is disposed on the outer periphery of the pressing member 231. An installation groove 234 is formed between the positioning member 233 and the pressing member 231. The outer shell 12 also includes a first side wall 122 and a second side wall 123, which are connected sequentially in the axial direction of the outer shell 12. The first side wall 122 is spaced apart from the inner shell 14 to form a first liquid storage cavity 121. The second side wall 123 surrounds and forms a second liquid storage cavity 16. The outer shell 12 is provided with a positioning groove 125 that cooperates with the positioning member 233. When the oil cup 1 is installed on the machine body 2, the second side wall 123 is fixed in the installation groove 234, and the positioning member 233 is inserted into the positioning groove 125.

[0063] Specifically, the number of positioning components 233 and positioning grooves 125 is not limited and can be set according to actual needs; the specific location of the positioning grooves 125 is also not limited. The positioning grooves 125 can be set on the outer wall surface of the first side wall 122, or on the outer wall surface of the second side wall 123, or simultaneously on the outer wall surfaces of both the first side wall 122 and the second side wall 123. The positioning components 233 and positioning grooves 125 provide positioning and visual guidance for the user, helping to align the oil cup 1 with the machine body 2 during assembly, helping the user quickly and accurately find the correct connection position between the oil cup 1 and the machine body 2, reducing assembly errors caused by misalignment, and thus improving assembly efficiency. In addition, the mounting groove 234 provides limiting and fixing functions for the second side wall 123, making the installation of the oil cup 1 on the machine body 2 more stable.

[0064] Optionally, in one embodiment, such as Figures 6 to 8 As shown, the top pressure member 231 includes a first enclosure wall 2311 and a first protrusion 2312 disposed on the first enclosure wall 2311. The first protrusion 2312 can extend into the second liquid storage cavity 16 and press against the sealing member 13 to drive the sealing member 13 to move from the first position to the second position. The positioning member 233 includes a second enclosure wall 2331 and a second protrusion 2332 disposed on the second enclosure wall 2331. The second protrusion 2332 can be inserted into the positioning groove 125. The second enclosure wall 2331 surrounds the outer periphery of the first enclosure wall 2311. The second enclosure wall 2331 and the first enclosure wall 2311 are spaced apart to form an installation groove 234.

[0065] It should be noted that the shape and number of the first protrusion 2312 and the second protrusion 2332 are not limited and can be set according to actual needs; the connection method between the first protrusion 2312 and the first enclosure 2311 is not limited, and the first protrusion 2312 and the first enclosure 2311 can be integrally formed or detachably connected; the connection method between the second protrusion 2332 and the second enclosure 2331 is also not limited, and the second protrusion 2332 and the second enclosure 2331 can be integrally formed or detachably connected; preferably, the first protrusion 2312 and the first enclosure 2311 are integrally formed, and the second protrusion 2332 and the second enclosure 2331 are integrally formed, which can increase the structural stability of the pressing member 231 and the positioning member 233.

[0066] In this embodiment, the first protrusion 2312 and the second protrusion 2332 are coaxially arranged and radially aligned, providing the user with a clear visual reference point and reducing installation errors caused by the user confusing the first protrusion 2312 and the second protrusion 2332. Specifically, since the aerosol generator 100 is usually small in size, the distance between the first protrusion 2312 and the second protrusion 2332 is also small, making it easy for the user to confuse the first protrusion 2312 and the second protrusion 2332 due to misreading, and thus mistakenly taking the first protrusion 2312 as the reference point during installation. However, by aligning the first protrusion 2312 and the second protrusion 2332 radially, both protrusions 2312 and 2332 are located in the same direction in the radial direction. Regardless of whether the user uses the first protrusion 2312 or the second protrusion 2332 as the reference point during installation, the user can quickly find the correct alignment direction, reducing installation errors.

[0067] Optionally, in one embodiment, such as Figure 8 As shown, the positioning component 233 also includes a sealing part 2341, which is disposed in the mounting groove 234. The sealing part 2341 can be sealed and connected to the second side wall 123 and the second enclosure wall 2331 respectively. Specifically, the sealing part 2341 can seal the gap between the second enclosure wall 2331 and the outer wall surface of the second side wall 123, preventing the atomized liquid in the second liquid storage chamber 16 from leaking out through the gap between the second enclosure wall 2331 and the outer wall surface of the second side wall 123, reducing the risk of oil leakage and improving the sealing performance of the aerosol generator 100.

[0068] Optionally, in one embodiment, such as Figure 2 , Figure 13 and Figure 14 As shown, the outer shell 12 of the oil cup 1 is provided with a first fastening member 11.
