The present disclosure relates to the field of aerosol generating technology, and more particularly, to an aerosol generating device.
An aerosol generating device is a product that can heat an atomizing liquid through an atomizer to generate an aerosol. Since the aerosol generating device is convenient to use and the taste of the aerosol can be changed by adjusting the atomizing liquid, the aerosol generating device has been widely and rapidly popularized in the domestic and foreign markets in recent years.
The existing aerosol generating device on the market employs a single or double sealing structure in a liquid storage cup, and thus there is a risk of leakage in the case of failure or extreme conditions of the sealing structure.

In some embodiments, the liquid storage cup 2 is disposed in the housing 1 of the aerosol generating device, the suction nozzle 11 is disposed on the housing 1, the first liquid storage space 12 is formed between the housing 1 and the liquid storage cup 2, the second liquid storage space 21 and the cell mounting cavity that are independently arranged are disposed in the interior of the liquid storage cup 2, and the liquid conducting hole is disposed on the liquid storage cup 2 to communicate the first liquid storage space 12 with the second liquid storage space 21. In some embodiments, the first sealing member 3 is disposed between the housing 1 and the liquid storage cup 2 and at a position away from the suction nozzle 11. The first sealing member 3 is of an annular structure, and has an outer peripheral surface and an inner circumference. The second sealing member 4 is disposed between the liquid storage cup 2 and the second liquid storage space 21 and at a position away from the suction nozzle 11. The third sealing member 5 is disposed at a position of the liquid storage cup 2 away from the suction nozzle 11, and the third sealing member 5 is located at the side of the second sealing member 4 away from the suction nozzle 11. The first sealing member 3, the second sealing member 4, and the third sealing member 5 together form a triple sealing structure, which, compared with a current structure in which the liquid storage cup 2 is sealed by using a single or double sealing structure, can prevent from failure of the single or double sealing structure or a leakage risk under an extreme condition, thereby improving the reliability of the sealing of the liquid storage cup 2.
In some embodiments, a positioning groove is disposed on an inner wall of the housing 1 or an outer wall of the liquid storage cup 2, and the first sealing member 3 is disposed in the positioning groove. At least two protruding sealing ribs are disposed on a side of the first sealing member 3 away from the bottom of the positioning groove, thereby improving sealing of the first liquid storage space 12 by the first sealing member 3, and preventing liquid leakage. Alternatively, the first sealing member 3 is integrally formed on the inner wall of the housing 1, and at least two protruding sealing ribs may be disposed in the inner circumference of the first sealing member 3, so that the sealing of the first liquid storage space 12 by the first sealing member 3 can be improved, thereby preventing liquid leakage. Alternatively, the first sealing member 3 is integrally formed on the outer wall of the liquid storage cup 2, and at least two protruding sealing ribs may be disposed on the outer periphery of the first sealing member 3, so that the sealing of the first liquid storage space 12 by the first sealing member 3 can be improved, thereby preventing liquid leakage.
In some embodiments, at least two protruding sealing ribs are disposed on an outer periphery of the second sealing member 4, thereby improving the sealing of the second liquid storage space 21 by the second sealing member 4, and preventing liquid leakage.
In some embodiments, a liquid injection hole is disposed on the second sealing member 4. A blocking member 42 is disposed in the liquid injection hole. At least two protruding sealing ribs are disposed on an inner wall of the liquid injection hole, thereby improving the sealing between the blocking member 42 and the liquid injection hole.

In some embodiments, at least two protruding sealing ribs are disposed on an outer periphery of the third sealing member 5, thereby improving the sealing of the liquid storage cup 2 by the third sealing member 5, and preventing liquid leakage.
In some embodiments, a sealing protruding structure 51 is disposed on the third sealing member 5 to block a side of the cell mounting cavity away from the suction nozzle 11, thereby preventing the atomizing liquid from entering the cell mounting cavity and causing the cell 13 to be short-circuited.
In some embodiments, the first sealing member 3 is made of a silicone or rubber material, which can improve the sealing of the liquid storage cup 2 by the first sealing member 3, and prevent liquid leakage.
In some embodiments, the second sealing member 4 is made of a silicone or rubber material, which can improve the sealing of the liquid storage cup 2 by the second sealing member 4 and prevent liquid leakage.
In some embodiments, the third sealing member 5 is made of a silicone or rubber material, which can improve the sealing of the liquid storage cup 2 by the third sealing member 5 and prevent liquid leakage.
In some embodiments, a mounting cavity 52 is formed between the third sealing member 5 and a side of the sealing protruding structure 51 facing away from the suction nozzle 11. A control plate 6 is provided in the mounting cavity 52, so that the control plate 6 is protected by providing the mounting cavity 52, thereby preventing the control plate 6 from being out of control or damaged due to contamination of the control plate 6 by the atomizing liquid.
In some embodiments, an atomizer tube 7 and an atomizing assembly 8 are provided in the liquid storage cup 2. Both ends of the atomizer tube 7 are contacted with the suction nozzle 11 and the atomizing assembly 8, respectively. The aerosol in the atomizing assembly 8 can be guided to the suction nozzle 11 by the atomizer tube 7. Liquid inlet holes are disposed on the atomizer tube 7 and the atomizing core 8 at corresponding positions to communicate the atomizing core 8 with the second liquid storage space 21, so that the atomizing liquid in the second liquid storage space 21 can be guided to the atomizing assembly 8 to supply the atomizing liquid to the atomizing assembly 8 through the liquid inlet holes. A tubular sealing portion 41 is disposed on the second sealing member 4 and extends into the atomizing assembly 8 from a side of the atomizing core 8 away from the suction nozzle 11, thereby improving the sealing between the atomizing assembly 8 and the second sealing member 4, and preventing the atomization leakage.
In some embodiments, an air passing cavity 53 is disposed on the third sealing member 5. The air passing cavity 53 is in communication with the tubular sealing portion 41. An air passing hole is disposed on the third sealing member 5 at the bottom of the air passing cavity 53. By providing the air passing cavity 53, it is possible to prevent the condensate in the air flow passing from flowing into the electronic components in the aerosol generating device, and to avoid the failure of circuit of the aerosol generating device.
In some embodiments, a bottom shell 9 is disposed at a side of the housing 1 away from the suction nozzle 11. The bottom shell 9 is capable of plugging a mounting cavity 52. The mounting cavity 52 is plugged by the bottom shell 9, so that a control plate 6 is prevented from being out of control or damaged due to contamination by the atomizing liquid. A gas inlet hole 91 is disposed on the bottom shell 9 and extends into the gas passing hole, and the gas inlet hole 91 together with the gas passing cavity 53 and the tubular sealing portion 41 forms a gas inlet passage for the atomizing assembly 8.
In some embodiments, a cell 13 is disposed in the cell mounting cavity. The atomizing assembly 8 includes a heating member 81 and a liquid conducting member 82 provided outside the heating member 81. The atomizing liquid in the liquid conducting member 82 is heated by the heating member 81 to generate an aerosol. Both the cell 13 and the heating element 81 are connected to the control plate 6, and the operating state of the heating element 81 is controlled by the control plate 6.
In summary, it will be readily appreciated by those skilled in the art that each of the above advantageous features may be freely combined and superimposed without conflict.
It will be apparent to those skilled in the art that for the convenience and brevity of the description, reference may be made to the corresponding procedures in the foregoing method embodiments for the specific working procedures of the apparatus, device and units described above, and details will not be described herein.
