In the above embodiment, the supporting seat 301 is installed on one side of the fixing seat 103 facing the liquid storage cavity 101. It is understood that the supporting seat 301 and the movable member 51 may also be disposed on a side of the fixed seat 103 away from the liquid storage chamber 101, such that the fixed seat 103 is located between the movable member 51 and the liquid storage chamber 101.

When the electron cigarette during operation, moving part 51 this moment is in the first position, annotates liquid mouth 50 and need be sealed completely by moving part 51 to avoid the tobacco tar to leak from annotating liquid mouth 50 the utility model discloses in, still be equipped with an annular seal 201 between fixing base 103 upper end and the suction nozzle subassembly 20 of annotating liquid mouth 50, be used for annotating liquid mouth 50 one end when sealed completely by moving part 51, tightly seal annotates the liquid mouth 50 other end, further seal annotating liquid mouth 50, in order to increase the gas tightness and prevent that the tobacco juice from leaking.

When the cigarette liquid of the electronic cigarette is used up and needs to be filled, a user only needs to push the movable member 51 to move from the first position to the second position by using the liquid filling nozzle, and fig. 3 is a schematic view of a state when the movable member 51 moves to the second position, at this time, the liquid filling port 50 is opened and can accommodate a liquid filling nozzle with a larger size to pass through.

Further, the movable member 51 includes a sealing sheet 511 and a baffle portion 512 extending from the sealing sheet 511 to the liquid filling opening 50, and the sealing sheet 511 is made of plastic or silica gel. And the shape of the movable piece 51 is matched with the shape of the liquid filling opening 50, wherein the shape of the sealing sheet 511 is matched with the shape of the liquid filling opening 50, and the baffle part 512 extends from the vertical direction of the sealing sheet 511 and is higher than the end surface of the supporting seat 301, so that the baffle part 512 can be conveniently pulled to rotate by the oil nozzle. The shape of the side portion of the partition 512 is adapted to the shape of the peripheral edge of the inner wall of the pouring outlet 50, so that the sealing sheet 511 can seal the pouring outlet 50 better. Specifically, the sealing plate 511 can rotate around the ventilation pipe 102 through the torsion spring 52 to open or seal the liquid injection port 50, so that the electronic cigarette can inject tobacco tar into the liquid storage cavity 101. In this embodiment, the pouring outlet 50 is a waist-shaped hole, and accordingly, the sealing sheet 511 is also a waist-shaped sheet. In other embodiments, the liquid inlet 50 and the movable member 51 may also have other suitable shapes, such as a circular, oval or polygonal hole.

It can be understood that one end of the torsion spring 52 can also abut against the baffle portion 512 protruding from the end surface of the sealing plate 511, so as to drive the sealing plate 511 to rotate.

When liquid injection is required, the user only needs to lightly push the baffle part 512 by the liquid injection nozzle to release the elastic fit between the baffle part 512 and the liquid injection opening 50, the sealing sheet 511 rotates or slides around the vent pipe 102 against the torsion spring 52 under the push of the liquid injection nozzle to open the liquid injection opening 50, and the larger the force applied to the baffle part 52 by the user through the liquid injection nozzle is, the larger the rotating angle or sliding distance of the sealing sheet 511 around the vent pipe 102 is, namely, the larger the size of the opened liquid injection opening 50 is. The technical scheme can accommodate the insertion of a large-size liquid injection nozzle into the liquid injection port 50 to inject tobacco tar into the liquid storage cavity 101, and the diameter of the liquid injection nozzle is larger than or equal to 2mm, for example. When the user pushes the baffle part 512 to release the elastic fit with the liquid injection port 50, the inner diameter of the torsion spring 52 is increased due to the selection of the torsion spring 52 against the direction of the torsion spring 52, that is, the inner diameter of the torsion spring 52 is larger than the outer diameter of the vent pipe 102, and at this time, the torsion spring 52 can rotate around the vent pipe 102 to drive the sealing piece 511 to rotate and slide, so that the liquid injection process is simple.

After the pouring, the user only needs to pull out the pouring nozzle from the pouring opening 50, and at this time, the sealing sheet 511 is reset under the elastic force of the torsion spring 52, so as to drive the sealing sheet 511 to move from the second position to the first position and keep the baffle part 512 on the sealing sheet 511 on the first position, as shown in fig. 2, so as to seal the pouring opening 50. For children, the liquid injection port 50 can be opened only through complex operation, so that the situation that the children easily open the liquid injection port 50 to contact or even eat the tobacco liquid in the liquid storage cavity 101 by mistake can be avoided, and the child protection effect is achieved. The above description is only an example of the present application and is not intended to limit the scope of the present application, and all modifications of equivalent structures and equivalent processes, which are made by the contents of the specification and the drawings, or which are directly or indirectly applied to other related technical fields, are intended to be included within the scope of the present application.
