In some embodiments of the present invention, as shown in fig. 2 to 6, the first sealing part 410 and the second sealing part 420 are arranged in the width direction of the housing 100.

Note that, the dimension in the width direction of the housing 100 is larger than the dimension in the thickness direction of the housing 100, and by dividing the seal 400 into the first seal portion 410 and the second seal portion 420 in the width direction of the housing 100, both the dimension of the first seal portion 410 and the dimension of the second seal portion 420 can be set larger, so as to facilitate processing of the first seal portion 410 and the second seal portion 420. Moreover, such an arrangement can effectively reduce the size of the seal 400 in the thickness direction of the housing 100, thereby reducing the space occupied by the seal 400 in the thickness direction of the housing 100, and the size of the housing 100 in the thickness direction can be set smaller, which is advantageous for achieving a slim design of the atomizing device 1.

Further, as shown in fig. 1, the air channel 120 is located on one side of the housing 100 in the width direction and extends along the length direction of the housing 100, so that the air channel 120 may not coincide with other structures of the atomization device 1 in the thickness direction of the housing 100, for example, the oil storage bin 110 and the air channel 120 may be adjacently arranged in the width direction of the atomization device 1 for the electronic cigarette, and the sum of the size of the air channel 120 in the thickness direction of the housing 100 and the thickness of the two side walls of the housing 100 in the thickness direction thereof is the thickness of the whole housing 100, which is beneficial to reducing the whole thickness of the housing 100, so that the ultra-thin design requirement of a user on the atomization device 1 for the electronic cigarette can be met.

Wherein, first sealing 410 is located the one side of keeping away from air flue 120 of second sealing 420, and first sealing 410 can directly end with the inner wall of keeping away from air flue 120 one side of shell 100 mutually, sets up like this and can avoid first sealing 410 and air flue 120 position to take place to interfere, is favorable to the air flue 120 structure, guarantees that air flue 120 and atomizing storehouse 130 can keep unobstructed, and smog flows more smoothly.

Alternatively, as shown in fig. 7 and 8, the atomizing core fixing structure 300 is formed with a ventilation chamber 330 communicating with the atomizing chamber 130, the atomizing core fixing structure 300 is formed with at least one ventilation hole 340 and at least one ventilation groove 350 on an outer peripheral surface thereof, the ventilation hole 340 penetrates through the outer peripheral wall of the atomizing core fixing structure 300 and communicates with the inside of the ventilation chamber 330, one end of the ventilation groove 350 is connected with the ventilation hole 340, the other end of the ventilation groove 350 penetrates through a side surface of the atomizing core fixing structure 300 along the housing 100 adjacent to the oil storage chamber 110, and a ventilation channel 430 is defined among the ventilation hole 340, the ventilation groove 350 and the sealing member 400. The first boss 311 is disposed around the outer periphery of the atomizing core mounting cavity 320, and the second boss 312 is disposed around the outer periphery of the ventilation cavity 330.

For example, the ventilation cavity 330 may extend along the axial direction of the atomizing core fixing structure 300, and the cross-sectional area of the ventilation cavity 330 may be larger than the cross-sectional area of the ventilation channel 430, so that sufficient gas may be contained in the ventilation cavity 330, and when the oil storage bin 110 needs to be ventilated, the gas in the ventilation cavity 330 may directly enter the oil storage bin 110 through the ventilation channel 430, thereby ensuring that the pressure in the oil storage bin 110 is normal. Moreover, the cross-sectional area of the ventilation channel 430 is set to be smaller, so that the ventilation elastic part 441 can easily cover the ventilation channel 430 while the air flow can normally pass through, thereby ensuring the reliable separation between the ventilation channel 430 and the oil storage bin 110 when the electronic cigarette does not work, ensuring the sealing performance of the oil storage bin 110 and preventing the oil storage bin 110 from leaking into the ventilation channel 430.

When the gas in the atomization bin 130 is used to perform pressure balance on the oil storage bin 110, the gas in the atomization bin 130 may sequentially flow through the ventilation chamber 330, the ventilation hole 340, the ventilation slot 350, and the first opening 442 into the oil storage bin 110.

In some embodiments of the present invention, as shown in fig. 1, the atomizing core 200 is located at one side of the atomizing core fixing structure 300 adjacent to the atomizing chamber 130, so that when the electronic cigarette is in operation, the tobacco tar can directly enter the atomizing chamber 130 after being atomized by the atomizing core 200 and flows to the air suction opening 150 along the air passage 120, thereby avoiding the retention of the smoke in the atomizing core fixing structure 300. In addition, the atomization core fixing structure 300 can be used as a part of the oil storage bin 110 at the side far away from the atomization bin 130, so that the volume of the oil storage bin 110 is enlarged, and the atomization device 1 can contain more tobacco tar.

In addition, the second sealing portion 420 is located at a side of the atomizing core 200 adjacent to the oil storage bin 110 along the length direction of the housing 100, so that the second sealing portion 420 can be filled between one end of the atomizing core fixing structure 300 facing the oil storage bin 110 and the inner wall of the housing 100, thereby preventing the smoke from entering a gap between the atomizing core fixing structure 300 and the housing 100, and further improving the sealing effect of the sealing member 400.

Moreover, when the sealing member 400 and the atomizing core fixing structure 300 are installed, because the sealing member 400 is located at one end of the installation structure of the atomizing core 200 facing the atomizing chamber 130, when the atomizing core fixing structure 300 is pushed to be installed into the housing 100 along the length direction of the housing 100, the atomizing core fixing structure 300 pushes the end sealing part 440, so that the sealing member 400 and the atomizing core fixing structure 300 can enter the housing 100 together, and the sealing member 400 and the atomizing core fixing structure 300 can be prevented from being separated from each other or changing relative positions in the installation process, thereby reducing assembly errors.
