 [0075] The embodiment provides a method for preventing smoke leakage of the electronic cigarette, and an on/off mechanism 2 for controlling the air passage to be closed or turned on is provided on the air passage of the electronic cigarette; The utility model comprises a fixed sleeve 21 and a movable core rod 23 which is elastically stretched and sleeved in the fixed sleeve 21; pressing the electronic cigarette causes the atomizer 1 and the battery assembly 4 to move toward each other, thereby driving the movable core rod 23 and the fixed sleeve 21 shaft The airway is closed to change the relative position to prevent the smoke oil from penetrating into the battery assembly 4 through the air passage to realize the smoke preventing leakage function.

 [0076] The present invention has the following technical features and beneficial effects:

 [0077] 1. By providing an on-off mechanism in the air passage of the electronic cigarette to control the opening and closing of the air passage, the leakage of the smoke oil is physically isolated in the atomization chamber by cutting the air passage, thereby avoiding leakage of smoke oil. The leakage of the battery component effectively prevents the electronic cigarette from leaking to the battery component during transportation and storage.

[0078] 2. The relative position between the atomizer and the battery assembly is limited by adopting a structure in which the upper connecting member and the lower connecting member are mutually restricted by the upper connecting protrusion and the lower connecting protrusion, thereby ensuring the electronic aerosolizer Stability of the connection structure with the battery assembly. [0079] 3. The closing of the vent hole is controlled by the frictional force of the sealing rubber ring disposed between the upper connecting member and the lower connecting member, so that the electronic cigarette can be closed without being inserted into the cigarette case, thereby preventing the vent hole from being closed. Children are slow to smoke e-cigarettes while playing.

 [0080] 4. By setting the air inlet cavity, the communication channel connecting the air passage and the outside is cut off at the same time, so that the electronic cigarette is in a double insurance state, and even if the switching mechanism fails, the electronic cigarette can not be completely closed. Still in an inoperable state, effectively preventing the occurrence of child aspiration accidents.

 [0081] 5. By adopting a structure in which the guiding protrusion cooperates with the guiding groove, the relative rotation between the upper connecting member and the lower connecting member is prevented, and the value between the atomizer and the battery assembly is prevented from moving circumferentially without occurrence. Rotate circumferentially.

 The above description is only a preferred embodiment of the present invention, and it should be noted that those skilled in the art can make several improvements and refinements without departing from the principles of the present invention. Retouching should also be considered as the scope of protection of the present invention.
