It will be appreciated that in other embodiments not shown, one end of the first elastic member 18 may also elastically abut against the upper cover 13, and the other end of the first elastic member 18 may correspondingly elastically abut against the upper blocking edge 162, and the lower blocking edge 161 may be omitted. When the unlocking member 14 is mounted to the upper cover 13, the first elastic member 18 is in a stretched state; when the unlocking piece 14 is disassembled, the first elastic piece 18 contracts and resets to drive the movable sleeve 16 to reset.

When the atomizer 100 or the electronic cigarette of the first embodiment of the present invention is assembled with the unlocking member 14 downward, the movable sleeve 16 moves downward under the supporting action of the unlocking member 14, the lower blocking edge 161 on the movable sleeve 16 extrudes the first elastic member 18 to deform, the movable sleeve 16 moves downward as a whole, and the first liquid inlet 163 and the second liquid inlet 172 can be aligned, so that the liquid storage cavity 121 is opened; when the unlocking member 14 is detached, the unlocking member 14 is separated from the movable sleeve 16, so that the supporting action of the unlocking member 14 on the movable sleeve 16 is eliminated, the first elastic member 18 extends upwards under the action of the elastic force of the first elastic member 18, and the lower blocking edge 161 at the top end of the first elastic member is driven to move upwards, so that the movable sleeve 16 moves upwards relative to the fixed sleeve 17, and finally the first liquid inlet 163 and the second liquid inlet 172 are staggered, so that the liquid storage cavity 121 is closed. Therefore, after the unlocking piece 14 is detached, even if the atomizing head 20 is detached, the smoke liquid can not flow out, so that the condition that the atomizing head 20 is detached randomly by children to contact or eat the smoke liquid by mistake is avoided, and the child protection effect is achieved.

Example two
