Wherein the cartridge 10 and the atomising head 20 constitute an atomiser (not shown).
Referring to fig. 4, the cartridge 10 includes a housing 11, a sealing member 12 mounted at one end of the housing 11, and a liquid sealing member (not shown) movably accommodated in the housing 11, wherein the liquid sealing member is movable to enable the liquid sealing member 13 to be connected with or separated from the sealing member 12 in a sealing manner. When the liquid sealing piece is connected with the sealing piece 12 in a sealing mode, smoke liquid is stopped and cannot flow out, and when the liquid sealing piece is separated from the sealing piece 12, the smoke liquid can flow out.
Specifically, the housing 11 is substantially a hollow cylindrical structure with an opening at the lower end, a liquid storage cavity 110 for storing liquid smoke is formed in the inner cavity of the housing 11, a vent pipe 111 is formed on the top wall of the housing 11 and extends downwards along the axial direction of the housing 11, the vent pipe 111 is a hollow pipe with two through upper and lower ends, a smoke suction port 112 is formed in the top of the housing 11, the smoke suction port 112 is communicated with the inner cavity of the vent pipe 111 and the outside atmosphere, and the smoke suction port 112 is used for a user to perform suction operation. In this embodiment, the vent pipe 111 and the housing 11 are integrally formed, but it should be understood that in other embodiments not shown, the vent pipe 111 and the housing 11 may be separate components, and they are connected when in use.
The sealing member 12 is accommodated in the lower end of the housing 11, the outer peripheral surface of the sealing member 12 is in sealing contact with the inner peripheral surface of the housing 11, and the sealing member 12 is a sealing material including silicone or rubber in order to improve the sealing property between the sealing member 12 and the housing 11.
Furthermore, the center of the sealing element 12 is provided with an insertion hole 121 along the axial direction of the sealing element 12, the insertion hole 121 penetrates through the upper and lower end surfaces of the sealing element 12, furthermore, the upper end surface of the sealing element 12 is recessed downwards along the axial direction of the sealing element 12 to form a slot 122 communicated with the insertion hole 121, and the diameter of the slot 122 is larger than that of the insertion hole 121.
The liquid sealing part is of a cylindrical structure with two through ends, the liquid sealing part comprises a liquid sealing part 13 and a sliding sleeve part 131 which are connected with each other, the liquid sealing part 13 is of a hollow sleeve-shaped structure with an opening at the lower end, and the liquid sealing part can be connected with the slot 122 in a sealing mode. The sliding sleeve portion 131 is formed by protruding the upper end surface of the liquid sealing portion 13, the sliding sleeve portion 131 is a tubular structure with a through upper end, the center of the upper end surface of the liquid sealing portion 13 is provided with a vent 132, and the vent 132 is communicated with both the liquid sealing part 13 and the sliding sleeve portion 131. The sliding sleeve portion 131 is slidably sleeved outside the vent pipe 111, and when the sliding sleeve portion 131 slides, the liquid sealing portion 13 can be driven by the sliding sleeve portion 131 to move. Specifically, when the sliding sleeve portion 131 slides downward relative to the ventilation pipe 111, the liquid sealing portion 13 can move downward under the driving of the sliding sleeve portion 131 and then gradually insert into the insertion slot 122, when the sliding sleeve portion 131 slides to the lower end face of the liquid sealing portion 13 and abuts against the bottom wall of the insertion slot 122, the liquid sealing portion 13 cannot continue to move downward, and the liquid sealing portion 13 is connected with the insertion slot 122 in a sealing manner, at this time, the liquid sealing member is in the liquid sealing position, and at this position, the liquid storage cavity 110 is sealed by the liquid sealing member, the smoke liquid in the liquid storage cavity 110 cannot flow out, and the smoke liquid is isolated from the atomizing head 20. When the sliding sleeve portion 131 slides upwards relative to the ventilation pipe 111, the liquid sealing portion 13 can move upwards under the driving of the sliding sleeve portion 131 to further gradually pull out the insertion slot 122, when the sliding sleeve portion 131 slides upwards to the position where the lower end face of the ventilation pipe 111 abuts against the upper end face of the liquid sealing portion 13, the liquid sealing piece cannot move upwards continuously, at the moment, the liquid sealing piece 13 is located at a liquid discharging position, the liquid sealing portion 13 completely pulls out the insertion slot 122 at the position, the liquid sealing piece opens the liquid storage cavity 110, smoke in the liquid storage cavity 110 can flow out, and the smoke and the atomizing head 20 are communicated with each other.
