When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0030] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0032] Please refer to the following: Figures 1 to 4The aerosol generating device provided in this application embodiment will now be described. The aerosol generating device includes a housing (not shown) and an airway switching component 20. The housing contains a first airway and a second airway, which are arranged parallel to each other and vertically. A first magnet 11 is located at the bottom of the housing, between the first and second airways. The first and second airways are symmetrically arranged on both sides of the first magnet 11. The aerosol generating device has two independent atomization systems. The corresponding atomization system is activated according to the opening and closing status of the first and second airways. The housing contains two aerosol bases with different flavors. After the corresponding atomization system is activated, it atomizes the aerosol base, and the atomized aerosol is then drawn out from the nozzle. Each atomization system includes a power supply, a corresponding airway, a liquid reservoir, and an atomizing component. Two liquid reservoirs contain different flavored aerosol bases. One atomizing component forms a first airflow channel, and the other forms a second airflow channel. The first airflow channel communicates with the first airway, and the second airflow channel communicates with the second airway. Both the first and second airflow channels are connected to a third airflow channel formed by the mouthpiece. When the first airway is open, the corresponding atomizing component activates and heats the aerosol base, atomizing it into an aerosol. The aerosol flows from the first airflow channel above the first airway to the third airflow channel for inhalation. When the second airway is open, the corresponding atomizing component activates and heats the aerosol base, atomizing it into an aerosol. The aerosol flows from the second airflow channel above the second airway to the third airflow channel for inhalation.

[0033] The airway switching component 20 is movably disposed on the bottom surface of the housing, and can move relative to the housing between a first position and a second position. When the airway switching component 20 is in the first position, it covers the air inlet end of the first airway, and at this time, the air inlet end of the second airway is connected to the external space, i.e., the first airway is closed and the second airway is open. When the airway switching component 20 is in the second position, it covers the air inlet end of the second airway, and the air inlet end of the first airway is connected to the external space, i.e., the first airway is open and the second airway is closed. In this way, when the airway switching component 20 moves relative to the housing, it can selectively cover the air inlet end of the first or second airway, thereby realizing the opening and closing of the first and second airways and realizing the airway switching operation.

[0034] The housing contains a support (not shown) and a fixing frame 10 connected to the bottom of the support. The fixing frame 10 is located near the bottom of the housing. The first and second air passages are vertically arranged within the support and located at the front and rear sides of the middle position. The fixing frame 10 is specifically connected and fixed to the support by a snap-fit ​​method. Multiple buckles are provided on the inner side wall of the fixing frame 10, and corresponding slots are provided at the bottom of the support, thus realizing the snap-fit ​​assembly between the support and the fixing frame 10. The fixing frame 10 is a shell with an open top and a roughly rectangular cross-section, with rounded corners. The air passage switching component 20 is slidably mounted on the fixing frame 10, meaning that the air passage switching component 20 can move linearly relative to the fixing frame 10.

[0035] The airway switching component 20 is provided with a second magnet 22. The magnetic poles of the second magnet 22 are the same as those of the first magnet 11 on the opposite side. That is, when the bottom surface of the first magnet 11 is the S pole, the top surface of the second magnet 22 is the S pole, and when the bottom surface of the first magnet 11 is the N pole, the top surface of the second magnet 22 is the N pole.

[0036] Because the magnetic poles of the two magnets in the airway switching component 20 and the fixing frame 10 are set to the same value, like poles repel each other. This magnetic force makes it easier for the airway switching component 20 to move on the housing. At the same time, the airway switching component 20 can stay stably when moving from one end to the other without easily moving. The stability after adjustment is improved, enhancing the comfort of operation and solving the problems of difficulty in turning and key jamming when using a toggle switch. The overall design uses fewer parts, has a simple structure, and low cost. The assembly difficulty between parts is greatly reduced, improving the assembly efficiency of the product.

[0037] Compared with the prior art, the aerosol generator provided in this application, by setting a first magnet 11 and a second magnet 22 on the airway switching component 20 and the housing respectively, with the magnetic poles of the opposite surfaces of the two magnets being set to be the same, makes it easier for the airway switching component 20 to move relative to the housing by utilizing the magnetic force of like poles repulsion. That is, the operation of the airway switching component 20 is smoother, solving the problems of difficulty in turning and key jamming when using a toggle, improving the comfort of operation. In addition, the airway switching component 20 can stay stably when moving from one end to the other and will not move easily, improving the stability after adjustment; it uses fewer parts, has a simple structure, and is easy to assemble.

[0038] See Figures 4 to 6Both the first magnet 11 and the second magnet 22 can be flat rectangular magnets, and the two magnets are the same size and shape, with the magnetic poles on opposite sides being the same. The bottom surface of the mounting bracket 10 has a first groove 110, in which the first magnet 11 is embedded. The first magnet 11 can be installed and fixed to the bottom surface of the housing by adhesive bonding or by an interference fit with the first groove 110. The first magnet 11 is completely housed in the first groove 110, with its bottom surface located within the groove 110, or its bottom surface is flush with the bottom surface of the mounting bracket 10.

[0039] The airway switching component 20 includes an air regulating plate 21, which has a roughly rectangular cross-section and rounded corners at all four edges. The air regulating plate 21 can be made of a non-magnetic material, specifically plastic. The two opposite ends of the air regulating plate 21 are slidably connected to a mounting bracket 10. Specifically, a sliding fit structure can be provided between the air regulating plate 21 and the mounting bracket 10 for proper use, ensuring that the air regulating plate 21 will not detach from the mounting bracket 10 after installation. A second groove 210 is provided on the back of the air regulating plate 21, and a second magnet 22 is fixed to the second groove 210. The second magnet 22 is completely contained within the second groove 210, with its top surface located within the groove, or its top surface is flush with the top surface of the air regulating plate. The second magnet 22 can be installed and fixed to the back of the air regulating plate 21 by adhesive bonding or by an interference fit with the second groove 210. The sliding direction of the air regulating plate 21 is set to be parallel to the width direction of the housing, that is, the air regulating plate 21 can slide back and forth along the width direction of the housing. Understandably, the airway switching component 20 can also be configured to rotate relative to the fixed frame 10 to achieve airway switching.

[0040] See Figure 1 , Figures 5 to 7 The back of the mounting bracket 10 is provided with parallel and spaced sliding grooves 12. Connecting ears 211 are provided at both ends of the air regulating plate 21 along its length. The connecting ears 211 on both sides slide into the corresponding sliding grooves 12, thus achieving a sliding assembly between the air regulating plate 21 and the housing through the sliding engagement of the connecting ears 211 and the sliding grooves 12. A barb 212 is provided at the end of the connecting ears 211 to prevent the air regulating plate 21 from detaching from the mounting bracket 10. Understandably, to ensure smooth sliding of the air regulating plate 21 relative to the mounting bracket 10, the position of the barb 212 ensures that the top surface of the air regulating plate 21 does not contact the mounting bracket 10 during sliding. That is, due to the magnetic force of the two magnets, the top surface of the air regulating plate 21 will not contact the bottom surface of the mounting bracket 10, requiring a larger force to make contact. This reduces the friction experienced by the air regulating plate 21 during sliding.

[0041] See Figure 5 , Figure 6The bottom surface of the air regulating plate 21 is provided with an anti-slip structure 214. Specifically, the bottom surface of the air regulating plate 21 has a protrusion 213 protruding relative to the bottom surface of the fixing frame 10. The width of the protrusion 213 is smaller than the width of the air regulating plate 21, and the length of the protrusion 213 is smaller than the length of the air regulating plate 21. An anti-slip structure 214 is provided on the surface of the protrusion 213. The anti-slip structure 214 may include one or more combinations of anti-slip textures, raised dots, and grooves. By providing an anti-slip structure 214 on the surface, friction can be increased to facilitate the finger movement of the air regulating plate. In this embodiment, the anti-slip structure 214 on the protrusion 213 includes a plurality of parallel and spaced strip grooves 215, the length direction of which is perpendicular to the sliding direction of the air regulating plate 21.

[0042] Please see Figures 4 to 6 The bottom surface of the mounting bracket 10 is recessed to form a receiving groove 14, in which at least a portion of the air regulating plate 21 is received, resulting in a smaller axial length of the product. Two sliding grooves 12 are formed at both ends of the receiving groove 14 in the width direction. The air inlet ends of the first air passage and the second air passage are both located at the bottom of the receiving groove 14. By providing the receiving groove 14 on the bottom surface of the housing, a portion of the air regulating plate 21 can be received in the receiving groove 14, and a portion of the boss 213 on the front side of the air regulating plate 21 extends out of the receiving groove 14, thus reducing the overall axial length of the aerosol generator.

[0043] The bottom surface of the mounting bracket 10 is provided with air inlet grooves 13 corresponding to the positions of the first and second air passages. Each air inlet groove 13 is embedded with a sealing gasket 30, which may be, but is not limited to, a silicone sealing gasket. The air inlet ends of the first and second air passages are in sealing contact with the top surface of the corresponding sealing gasket 30, and the sealing gasket 30 is coaxially arranged with the corresponding air passage. The top surface of the sealing gasket 30 is provided with a blind groove 33, which is coaxially arranged with the corresponding air passage above it. The sealing gasket 30 has an air passage 31 that penetrates through the upper and lower surfaces. The air passage 31 communicates with the corresponding air passage through the blind groove 33. External airflow communicates with the corresponding air passage through the air passage 31. The air passage switching component 20 can selectively make sealing contact with one of the sealing gaskets 30 and cover the corresponding air passage 31. In other words, during the back-and-forth sliding of the air regulating plate 21, the air regulating plate 21 makes sealing contact with one of the sealing gaskets 30, sealing the air passage 31 of that sealing gasket 30, while the air passage 31 of the other sealing gasket 30 is not covered by the air regulating plate 21. In this way, the back-and-forth sliding of the air regulating plate 21 can realize the switching of air passages. The sealing gasket 30 has multiple air passages 31. The bottom end of the first air passage abuts against the top surface of the corresponding sealing gasket 30, and the bottom end of the second air passage abuts against the top surface of the corresponding sealing gasket 30. The air passages are connected to the external space through the air passages 31 on the sealing gasket 30.

[0044] The bottom surface of the sealing gasket 30 is provided with at least one ring of sealing ribs 32. The air passage switching component 20 is in sealing contact with the sealing ribs 32, that is, the sealing gasket 30 achieves elastic sealing contact with the air regulating plate 21 through the sealing ribs 32. The sealing ribs 32 form a ring, and the air passage holes 31 are located within the area enclosed by the ring-shaped sealing ribs 32. The sealing gasket 30 has three air passage holes 31, all of which are located within the area enclosed by the sealing ribs 32.

[0045] See Figure 4 and Figure 6 A convex ring 130 and an annular groove 34 are provided between the outer peripheral wall of the sealing gasket 30 and the inner peripheral wall of the air intake groove 13, respectively. The convex ring 130 is embedded in the annular groove 34, thereby assembling and fixing the sealing gasket 30 to the air intake groove 13. Specifically, the outer peripheral wall of the sealing gasket 30 is provided with an annular groove 34, and the inner peripheral wall of the air intake groove 13 is provided with a convex ring 130 that fits the annular groove 34. The convex ring 130 is embedded in the annular groove 34. The assembly between the sealing gasket 30 and the air intake groove 13 is achieved through the cooperation of the convex ring 130 and the annular groove 34. In this way, the sealing gasket 30 is stably fixed in the fixing frame 10, and the sealing gasket 30 is not easy to fall out of the fixing frame 10.

[0046] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
