The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0034] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0035] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0036] This application provides an aerosol generating device, such as... Figures 1 to 9 As shown, the aerosol generating device includes: a shell 1, a liquid storage bottle 2, an atomizing device 3, and a control valve 4. A support platform 5 is provided inside the shell 1. The liquid storage bottle 2 and the atomizing device 3 are disposed opposite each other inside the shell 1 and are respectively disposed at both ends of the support platform 5. The control valve 4 is rotatably disposed on the support platform 5. The control valve 4 is provided with a first through hole 41, and the support platform 5 is provided with a second through hole 51.

[0037] When the control valve 4 is rotated to the first position, the first through hole 41 and the second through hole 51 are coaxially arranged, and the liquid storage bottle 2 and the atomizing device 3 are connected through the first through hole 41 and the second through hole 51.

[0038] When the control valve 4 is rotated to the second position, the first through hole 41 moves away from the second through hole 51, and the control valve 4 seals the second through hole 51.

[0039] The working principle of the aerosol generating device provided in this application embodiment is as follows: the storage bottle 2 stores the aerosol generating medium; when the user needs to aspirate, the control valve 4 is rotated to the first position, such as... Figure 6 , 8 As shown, the first through-hole 41 and the second through-hole 51 are coaxially arranged, so that the liquid storage bottle 2 and the atomizing device 3 are connected through the first through-hole 41 and the second through-hole 51, so that the liquid storage bottle 2 can supply the aerosol generating medium to the atomizing device 3 through the first through-hole 41 and the second through-hole 51. The atomizing device 3 adsorbs the aerosol generating medium and heats the aerosol generating medium to generate aerosol. When the user needs to control the liquid supply from the liquid storage bottle 2 to the atomizing device 3, the control valve 4 is rotated between the first position and the second position to control the degree of obstruction of the second through-hole 51 by the control valve 4, thereby controlling the flow rate of the aerosol generating medium through the first through-hole 41. When the user does not need to aspirate, or to perform negative pressure tests or high temperature tests, the control valve 4 is rotated to the second position, such as... Figure 5 , 9 As shown, the first through hole 41 is moved away from the second through hole 51, and the second through hole 51 is completely blocked by the control valve 4, so that the aerosol generating medium cannot enter the atomizing device 3 through the support platform 5.

[0040] The beneficial effects of the aerosol generating device provided in this application embodiment are as follows: by adjusting the connection between the liquid storage bottle 2 and the atomizing device 3 through the control valve 4, the flow rate of the aerosol generating medium entering the atomizing device 3 can be controlled, which can prevent the liquid storage bottle 2 from continuously supplying the aerosol generating medium to the atomizing device 3 under any circumstances, thereby avoiding leakage and reducing the wicking situation caused by excessive supply of aerosol generating medium during the suction process; and in negative pressure test and high temperature test environments, the control valve 4 can be rotated to the second position to close the connection between the liquid storage bottle 2 and the atomizing device 3, thereby reducing the risk of oil leakage caused by the test.

[0041] like Figures 1-3 As shown in Figures 8 and 9, the control valve 4 further includes a rotating plate 42 and a paddle 43. The rotating plate 42 is rotatably disposed at one end of the support platform 5 away from the liquid storage bottle 2. The first through hole 41 is opened on the rotating plate 42. The paddle 43 is connected to the side wall of the rotating plate 42. The side wall of the outer shell 1 is provided with a sliding groove 11. The paddle 43 is slidably disposed in the sliding groove 11. The two sides of the sliding groove 11 are the first position and the second position, respectively.

[0042] When the lever 43 is moved to the first position, the first through hole 41 and the second through hole 51 are coaxially arranged;

[0043] When the lever 43 is moved to the second position, the rotating plate 42 seals the second through hole 51.

[0044] In this embodiment, when the user needs suction, the lever 43 is moved to the first position of the slide groove 11, such as... Figure 6 , 8 As shown, the first through hole 41 and the second through hole 51 are coaxially arranged, so that the liquid storage bottle 2 and the atomizing device 3 are connected through the first through hole 41 and the second through hole 51, so that the liquid storage bottle 2 can supply the aerosol generating medium to the atomizing device 3 through the first through hole 41 and the second through hole 51. The atomizing device 3 adsorbs the aerosol generating medium and heats the aerosol generating medium to generate aerosol. When the user needs to control the liquid supply from the liquid storage bottle 2 to the atomizing device 3, the lever 43 is moved between the first position and the second position of the slide groove 11 to control the degree of obstruction of the second through hole 51 by the rotating plate 42, thereby controlling the flow rate of the aerosol generating medium through the first through hole 41. When the user does not need to aspirate, or to perform negative pressure tests and high temperature tests, the lever 43 is moved to the second position of the slide groove 11, such as... Figure 5 , 9 As shown, the first through hole 41 is moved away from the second through hole 51, and the second through hole 51 is completely blocked by the rotating plate 42, so that the aerosol generating medium cannot enter the atomizing device 3 through the support platform 5.

[0045] In this embodiment, the paddle 43 slides in the groove 11, and the paddle 43 drives the rotating plate 42 to rotate on the support platform 5, thereby adjusting the relative position of the first through hole 41 and the second through hole 51, and finally achieving the purpose of controlling the flow rate of the aerosol generating medium entering the atomizing device 3.

[0046] Furthermore, the control valve 4 also includes a limiting plate 44, the limiting plate 44 and the lever 43 are disposed on opposite sides of the rotating plate 42, the support platform 5 is provided with a communicating receiving groove 52 and a limiting groove 53, the receiving groove 52 is disposed at one end of the support platform 5 away from the liquid storage bottle 2; the rotating plate 42 is rotatably disposed in the receiving groove 52, and the limiting plate 44 is slidably disposed in the limiting groove 53;

[0047] When the lever 43 is moved to the first position, the limiting piece 44 abuts against the groove wall of the limiting groove 53 near the second position;

[0048] When the lever 43 is moved to the second position, the limiting piece 44 abuts against the groove wall of the limiting groove 53 near the first position.

[0049] In this embodiment, the cooperation between the limiting piece 44 and the limiting groove 53 not only limits the stroke of the paddle 43, ensuring that the first through hole 41 and the second through hole 51 are coaxially arranged in the first position and the second through hole 51 is sealed by the rotating piece 42 in the second position, but also facilitates prompting the user to move to the first or second position when the user feels resistance, thereby improving the user experience.

[0050] like Figure 2 , 5 As shown in Figure 7, further, the outer shell 1 is provided with an air inlet (not shown), the outer shell 1 and the liquid storage bottle 2 have a first air passage 12, the support platform 5 is provided with a second air passage 54 spaced apart from the second through hole 51, the atomizing device 3 is provided with an inlet channel 31 and an atomizing channel 32 spaced apart, and the atomizing device 3 is provided with an outlet 37 communicating with the atomizing channel 32. The air inlet, the first air passage 12, the second air passage 54, the atomizing channel 32 and the outlet 37 are sequentially connected; when the control valve 4 is rotated to the first position, the inlet channel 31 communicates with the first through hole 41.

[0051] In this embodiment, when the user needs suction, first rotate the control valve 4 to the first position, such as... Figure 6 , 8As shown, the liquid inlet channel 31, the first through hole 41 and the second through hole 51 are connected, so that the aerosol generating medium in the liquid storage bottle 2 enters the atomizing device 3; then when the user draws through the air outlet 37, the external gas enters the outer shell 1 through the air inlet, and then enters the atomizing channel 32 through the first air passage 12 and the second air passage 54. The atomizing device 3 heats the aerosol generating medium to generate aerosol, and finally the aerosol is discharged to the outside through the air outlet 37.

[0052] In this embodiment, the atomizing device 3 is provided with an atomizing channel 32 and a liquid inlet channel 31, and the control valve 4 controls whether the liquid inlet channel 31 is connected to the liquid storage bottle 2, so as to prevent the aerosol generating medium from flowing directly into the atomizing channel 32 and reduce the risk of leakage.

[0053] like Figure 5 As shown, the atomizing device 3 further includes a housing 33, a base 34, a liquid-guiding cotton 35, and an atomizing core 36; the air outlet 37 is provided on the housing 33, the liquid-guiding cotton 35 is provided with a first atomizing channel 321 penetrating both ends, the base 34 is connected to the housing 33 and supports the liquid-guiding cotton 35, the liquid inlet channel 31 is provided on the base 34, and the base 34 is also provided with a second atomizing channel 322 spaced apart from the liquid inlet channel 31, the first atomizing channel 321 and the second atomizing channel 322 communicate to form the atomizing channel 32, and the atomizing core 36 is provided on the liquid-guiding cotton 35 and located in the first atomizing channel 321.

[0054] In this embodiment, when the user needs suction, first rotate the control valve 4 to the first position, such as... Figure 6 , 8 As shown, the liquid inlet channel 31, the first through hole 41 and the second through hole 51 are connected, so that the aerosol generating medium in the liquid storage bottle 2 flows through the liquid inlet channel 31 to the liquid guide cotton 35, and the liquid guide cotton 35 adsorbs the aerosol generating medium; when the user draws through the air outlet 37, the external gas enters the outer shell 1 through the air inlet, and then enters the second atomization channel 322 through the first air passage 12, the second air passage 54 and the first atomization channel 321. At this time, the atomizing core 36 heats the aerosol generating medium to generate aerosol, and finally the aerosol is discharged outward through the air outlet 37.

[0055] Furthermore, the outer shell 1 has an installation cavity 13 and a fixing cavity 14 spaced apart, and the support platform 5 is located between the installation cavity 13 and the fixing cavity 14; the installation cavity 13 has an opening 15 at one end away from the fixing cavity 14, and the atomizing device 3 is detachably installed in the installation cavity 13 through the opening 15. The atomizing device 3 moves along the length of the installation cavity 13, and the liquid storage bottle 2 is fixed in the fixing cavity 14.

[0056] In this embodiment, when the atomizing device 3 needs to be replaced, the control valve 4 is rotated to the second position, so that the first through hole 41 is away from the second through hole 51, and the second through hole 51 is completely blocked by the control valve 4, so that the aerosol generating medium cannot flow out through the support platform 5; then, the atomizing device 3 is taken out from the mounting cavity 13 through the opening 15; finally, the new atomizing device 3 is placed into the mounting cavity 13 through the opening 15.

[0057] In this embodiment, the outer shell 1 includes a mounting cavity 13 and has an opening 15, so that the atomizing device 3 can be detachably installed in the mounting cavity 13 to meet the user's need to replace the atomizing device 3.

[0058] Furthermore, the air inlet is connected to the fixed cavity 14.

[0059] like Figures 5-7 As shown, the outer shell 1 further includes a support cylinder 16, and the base 34 is provided with a snap-fit ​​cylinder 38 at the end away from the shell 33. The outer wall of the snap-fit ​​cylinder 38 is snapped into the inner wall of the support cylinder 16. When the control valve 4 is rotated to the first position, the liquid inlet channel 31, the snap-fit ​​cylinder 38, the support cylinder 16 and the first through hole 41 are connected.

[0060] In this embodiment, the connection accuracy between the atomizing device 3 and the mounting cavity 13 is improved by the support cylinder 16 and the snap-fit ​​cylinder 38, and the atomizing device 3 can be prevented from falling out of the mounting cavity 13.

[0061] Furthermore, a silicone part 6 is provided between the outer wall of the snap-fit ​​cylinder 38 and the inner wall of the support cylinder 16; this increases the friction between the snap-fit ​​cylinder 38 and the support cylinder 16, further preventing the atomizing device 3 from falling out of the mounting cavity 13.

At this time, the power supply device 7 supplies power to the atomization core 36, and the atomization core 36 heats the aerosol generating medium to generate aerosol. Finally, the aerosol is discharged outward through the air outlet 37.

[0064] like Figure 2As shown, the power supply device 7 further includes a storage battery 71 and a conductive element 72 electrically connected to the storage battery 71. The conductive element 72 protrudes from the sealed cavity 17. The atomizing device 3 has a power receiving element 39 at one end away from the air outlet 37.

[0066] Furthermore, the power supply device 7 also includes a PCB board 73, and the conductive element 72 and the battery 71 are electrically connected to the PCB board 73 respectively.

[0067] In this embodiment, the PCB board 73 controls whether the battery 71 supplies power to the atomizing device 3.
