[0027] Refer to Figures 1 to 5, the present utility model provides an aerosol generating device 100, which includes an atomization component 110 and a power supply component 120. The atomization component 110 includes an oil storage cavity and an atomization core installed in the oil storage cavity. The atomization core heats and atomizes the e-liquid in the oil storage cavity to generate aerosol for users to inhale. The power supply component 120 is used to supply electrical energy to the atomization component 110 to make the atomization component 110 work. The power supply component 120 forms a receiving cavity 124, and the atomization component 110 is detachably installed in the receiving cavity 124. The bottom of the atomization component 110 is provided with a mounting base, and the mounting base is spaced from the bottom of the receiving cavity 124. Among them, the aerosol generating device 100 further includes a sealing member 130, the sealing member 130 is installed in the receiving cavity 124, and the atomization component 110, the sealing member 130 and the power supply component 120 are sealingly connected on the cross-sectional area of the receiving cavity 124.

[0028] Among them, the power supply component 120 includes a housing 121, a bracket 122 and a gasket 123. The housing 121 is a hollow thin-walled structure. The bracket 122 is installed in the housing 121. The bracket 122 and the housing 121 jointly enclose the receiving cavity 124. The top of the bracket 122 is wound with a gasket 123 to make the bracket 122 and the housing 121 sealingly connected, avoiding the phenomenon that the condensate in the receiving cavity 124 leaks into the power supply component 120 from the mating part of the bracket 122 and the housing 121.

[0029] Specifically, the sealing member 130 is made of silicone material, and the sealing member 130 has good flexibility. The atomization component 110 and the power supply component 120 are sealingly connected on the horizontal plane through the sealing member 130. The side wall of the atomization component 110 abuts against the side wall of the sealing member 130, and the side wall of the sealing member 130 facing away from the atomization component 110 closely abuts against the side wall of the receiving cavity 124. The acting forces on the side wall of the atomization component 110 can cancel each other out in the horizontal plane direction, improving the sealing performance between the atomization component 110 and the power supply component 120.

[0030] After adopting the above technical solution, by arranging the sealing member 130 in the receiving cavity 124, the sealing member 130 is arranged at the bottom or side wall of the receiving cavity 124, and the atomization component 110, the sealing member 130 and the power supply component 120 are sealingly connected on the cross-sectional area of the receiving cavity 124. Compared with the atomization component 110 and the power supply component 120 in the vertical direction, the atomization component 110 and the power supply component 120 are more tightly sealed in the horizontal plane direction, reducing the possibility of loose sealing or popping out from the open end of the receiving cavity 124 between the atomization component 110 and the power supply component 120, making the air flow of the aerosol generating device 100 stable and facilitating the normal operation of the aerosol generating device 100.

[0031] In an alternative embodiment, the seal 130 protrudes from the bottom of the accommodation cavity 124. The seal 130 is an annular sealing boss. The seal 130 surrounds to form a sealing hole. A step 111 adapted to the sealing hole is formed at the bottom of the atomization assembly 110. The step 111 is in interference fit with the sealing hole. The seal 130 can be provided on one of the atomization assembly 110 and the power supply assembly 120. In the present utility model, the seal 130 is installed at the bottom of the accommodation cavity 124. An air flow channel is provided at the bottom of the atomization assembly 110. The seal 130 is annularly arranged. The seal 130 is used to seal the bottom of the atomization assembly 110 to ensure a stable intake air volume of the air flow channel. The seal 130 surrounds to form a sealing hole at the bottom of the accommodation cavity 124. A step 111 is formed at the edge of the bottom of the atomization assembly 110. When the atomization assembly 110 is installed in the accommodation cavity 124, the step 111 is inserted into the sealing hole, so that the atomization assembly 110 and the seal 130 are sealed and connected in the horizontal plane.

[0032] It can be understood that the seal 130 can be provided with a spire-shaped structure. The cross section of the seal 130 can be triangular or dam-shaped, which is not limited herein. A groove adapted to the seal 130 is provided at the bottom of the atomization assembly 110. The seal 130 is in sealing contact with both side walls of the groove, improving the sealing performance of the seal 130 and the groove in the horizontal plane.

[0033] In this embodiment, the seal 130 abuts against the side wall of the accommodation cavity 124. One side of the seal 130 that cooperates with the accommodation cavity 124 is a right-angle side, facilitating the close fit of the seal 130 and the accommodation cavity 124. The side wall of the accommodation cavity 124 supports the seal 130, facilitating the cooperation of the seal 130 and the step 111.

[0034] In this embodiment, the seal 130 is formed with an inclined surface 131 on one side of the accommodating cavity 124, and the thickness of the seal 130 is tapered in a direction away from the bottom of the accommodating cavity 124. The inclined surface 131 on the seal 130 faces the atomizing assembly 110, that is, the distance between the inclined surface 131 and the side wall of the accommodating cavity 124 is tapered in a direction away from the bottom of the accommodating cavity 124. The step 111 on the atomizing assembly 110 is a right-angle surface corresponding to the inclined surface 131. When the atomizing assembly 110 is installed downward in the accommodating cavity 124, the step 111 and the seal 130 are in interference fit in the horizontal direction, and the step 111 and the inclined surface 131 are more firmly engaged. The angle between the inclined surface 131 and the horizontal plane is in the range of 30° to 60°. By providing the inclined surface 131 on the seal 130, the influence of manufacturing errors on the sealing performance is reduced, ensuring the sealed connection between the power supply assembly 120 and the atomizing assembly 110 on the horizontal plane.

[0035] In an alternative embodiment, the power supply assembly 120 further includes a housing 121, a bracket 122, and a gasket 123. The housing 121 and the bracket 122 enclose the accommodating cavity 124. The gasket 123 is disposed around the periphery of the bracket 122. The bracket 122 and the housing 121 are sealed and connected through the gasket 123, and the gasket 123 and the seal 130 are integrally formed. The gasket 123 is clamped between the housing 121 and the bracket 122 to firmly connect the gasket 123 and the bracket 122, thereby achieving the effect of fixing the seal 130. The gasket 123 and the seal 130 are integrally formed, which is convenient for production and manufacturing, and avoids the phenomenon of poor sealing due to the shaking or offset of the seal 130.

[0036] In this embodiment, the gasket 123 further includes a first sealing portion 126 for sealing the airflow sensor. The gasket 123 covers the periphery of the end of the bracket 122. The gasket 123 extends downward with a first sealing portion 126 and a second sealing portion 127. The first sealing portion 126 is used to seal the airflow sensor, and the second sealing portion 127 is used to seal the air regulating member. The first sealing portion 126 and the second sealing portion 127 are integrally formed with the gasket 123, which is convenient for the assembly of the power supply assembly 120. The air regulating member is provided on the side wall of the housing 121 and is disposed near the end of the bracket 122, which is convenient for the second sealing portion 127 to be integrally formed with the gasket 123.

[0037] In this embodiment, an air through-hole 125 is formed at the bottom of the accommodation cavity 124. The atomization assembly 110 is provided with an air flow channel, and the air through-hole 125 is communicated with the air flow channel. Since the atomization assembly 110 is sealingly connected to the side wall of the accommodation cavity 124, the air flow entering the air flow channel is supplied by the air through-hole 125. By controlling the air intake amount of the air through-hole 125, the draw resistance of the aerosol generating device 100 can be ensured, so as to facilitate maintaining the atomization taste of the aerosol generating device 100 and improving the user experience.

[0038] In an alternative embodiment, the seal 130 is installed on the side wall of the accommodation cavity 124 and is spaced from the bottom of the accommodation cavity 124. The seal 130 can be a sealing ring, which is embedded in the side wall of the accommodation cavity 124, and the sealing ring is spaced from the bottom of the accommodation cavity 124. The distance between the sealing ring and the accommodation cavity 124 is between 5 mm and 15 mm. Setting the sealing ring on the side wall of the accommodation cavity 124 not only facilitates the sealing connection between the atomization assembly 110 and the power supply assembly 120 on the horizontal plane, but also facilitates fastening the atomization assembly 110 and the power supply assembly 120 together, reducing the possibility of the atomization assembly 110 detaching from the accommodation cavity 124.

[0039] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention.
