Referring to fig. 9 in combination, fig. 9 is a schematic cross-sectional structure of a host according to some embodiments of the utility model.

In some embodiments, to increase the sensitivity of the air switch 430, a gap is formed between one side of the air switch 430 abutting against the bottom wall of the second accommodating groove 2401, and the opposite side of the air switch and the second positioning groove 307. Optionally, the air switch 430 is fixed in the second accommodating groove 2401 by a sealing member, and the sealing member is made of flexible materials such as silica gel, rubber, etc., and is disposed between the sidewall of the second accommodating groove 2401 and the air switch 430 in an interference manner. The air switch 430 may also be clamped to a side wall of the second positioning slot 307.

The limiting portion 130 of the first seat 100 abuts against the abutting portion 210 of the second seat 200 to support the second seat 200, so that a side of the second seat 200 facing the third seat 300 can be spaced from the third seat 300, and a gap can be formed between the air switch 430 and the third seat 300, and meanwhile, the main board 420 can be prevented from being damaged due to too large interference force between the second seat 200 and the third seat 300.

The limiting parts 130 are at least two and symmetrically arranged on two opposite sides of the side part 120 to stably support the second seat 200. The outer periphery of the second seat 200 abuts against the side 120 of the first seat 100, and cooperates with the first seat 100 to form the accommodating cavity 104. Optionally, the abutting portion 210 of the second seat 200 abuts against the side portion 120, and cooperates with the side portion 120 and the bottom portion 110 to form the accommodating cavity 104. In some embodiments, the receiving cavity 104 may also be formed by the carrier 220 in cooperation with the side 120 and the bottom 110.

Optionally, the accommodating groove 101 formed by surrounding the bottom 110 and the side 120 is partially matched with the second seat 200 to form the accommodating cavity 104, and the other part forms the butt joint groove 105. Wherein, the bottom wall of the butt-joint groove 105 is formed by the abutting portion 210 of the second seat 200, and the side wall of the butt-joint groove 105 is formed by the side portion 120. The docking slot 105 is used to receive a portion of the atomizer 10 when the atomizer 10 is docked with the host 20. Wherein, the electrode terminal 440 is penetrated through the bottom wall of the butt-joint groove 105. The magnetic attraction member 460 is provided on the bottom wall of the docking slot 105 and is partially exposed in the docking slot 105.

In some embodiments, the peripheral edge of the abutting portion 210 may also abut against an end of the side portion 120 facing away from the bottom portion 110 to form the accommodating cavity 104 in cooperation with the side portion 120 and the bottom portion 110, where the accommodating groove 101 completely forms the accommodating cavity 104.

When the host 20 is assembled to form the accommodating cavity 104, the second through hole 202 on the abutting portion 210 communicates with the accommodating cavity 104. The bearing portion 220 and the third seat 300 are both disposed in the accommodating cavity 104. The gas channel 204 of the bearing portion 220 is located in the accommodating cavity 104, and one end of the gas channel 204 is communicated with the second through hole 202, and the other end is communicated with the third through hole 203. The gas entering the accommodating chamber 104 from the first through hole 102 can flow to the fourth through hole 302 through the vent groove 303, and further enter the gas channel 204 through the third through hole 203 communicating with the fourth through hole 302, and further flow out of the accommodating chamber 104 from the second through hole 202.

Alternatively, the battery 410 provided on the carrying part 220 has an end exposed to the receiving cavity 104. The first electrode 4101 and the second electrode 4102 of the battery 410 are respectively positioned at opposite ends of the battery 410 exposed to the accommodating chamber 104.

Since the first electrode 4101 and the second electrode 4102 of the battery 410 may release substances with safety risks such as flame when the battery 410 is damaged, in some embodiments, the first electrode 4101 of the battery 410 is disposed towards the first portion 1201 of the side portion 120 exposed to the interior of the accommodating cavity 104, and the second electrode 4102 of the battery 410 is disposed towards the second portion 1202 of the side portion 120 exposed to the interior of the accommodating cavity 104, so as to avoid leakage of harmful substances such as flame released by the first electrode 4101 or the second electrode 4102 to the outside of the host 20 through the first through hole 102 provided at the bottom 110 or the second through hole 202 provided at the abutting portion 210.

The first portion 1201 and the second portion 1202 may be any two portions of the side portion 120 exposed to the accommodating cavity 104, and since the side portion 120 is located between the abutting portion 210 and the bottom portion 110, even if the battery 410 releases harmful substances through the first electrode 4101 and the second electrode 4102, the harmful substances are blocked by the side portion 120 and are difficult to leak out of the host 20 through the first through hole 102 and the second through hole 202.

Alternatively, the side portion 120 is disposed perpendicular to the abutting portion 210 and the bottom portion 110, and the first electrode 4101 and the second electrode 4102 of the battery 410 are disposed opposite to the side portion 120, so as to minimize leakage of harmful substances released by the battery 410 due to damage to the outside of the host 20. Of course, embodiments of the present utility model are not limited thereto. The side portion 120 may be designed in any shape that can perform its function as needed, and the connection angle thereof with the abutting portion 210 or the bottom portion 110 may be designed as needed as long as the orientations of the first electrode 4101 and the second electrode 4102 are made to be deviated from the positions of the respective through holes.

Referring to fig. 10, fig. 10 is a schematic cross-sectional view of an electronic atomization device according to some embodiments of the utility model.

Optionally, when the atomizer 10 is inserted into the docking slot 105 to dock with the host 20, the electrode terminals 440 are abutted against the atomizer 10 to realize electrical connection, and the magnetic attraction member 460 is attracted to the atomizer 10 to realize stable docking of the atomizer 10 with the host 20.

The atomizer 10 has an air inlet 501, an air outlet 502 and an atomizing passage 503. The air inlet 501 is arranged on one side of the atomizer 10 close to the abutting portion 210, the air outlet 502 is arranged on the other side of the atomizer 10 far away from the abutting portion 210, and one end of the atomizing channel 503 is communicated with the air inlet 501, and the other end is communicated with the air outlet 502. Of course, the air outlet 502 may be provided in other positions of the atomizer 10 outside the docking slot 105.

The portion of the atomizer 10 provided with the air inlet 501 and the portion of the abutting portion 210 provided with the second through hole 202 are spaced apart, so that the air flowing out of the accommodating cavity 104 from the second through hole 202 can further flow into the atomizing channel 503 through the air inlet 501 and further flow out through the air outlet 502. In other words, the air outlet 502 of the atomizer 10 communicates with the first through-hole 102 of the main body 20.

In summary, according to the utility model, the outer peripheral edge of the second seat body is abutted against the side portion of the first seat body to form the accommodating cavity for accommodating the battery in a matching manner, the first electrode of the battery is arranged towards the first portion of the side portion exposed to the accommodating cavity, and the second electrode is arranged towards the second portion of the side portion exposed to the accommodating cavity, so that the possibility that leaked substances are output to the outside of the electronic atomization device through the first through hole at the bottom of the first seat body and the air outlet of the atomizer when the battery is damaged is reduced, and the safety risk of the electronic atomization device in use is reduced.
