A battery pack includes a battery main body and a cover assembly arranged on the battery main body. The battery main body has a mounting groove. A side wall of the mounting groove is provided with a clamping portion. The battery main body is electrically connected to a switch. The cover assembly includes a cover movably arranged in the mounting groove, a locking structure arranged on the cover, and an abutting member arranged, corresponding to the switch, between the mounting groove and the cover. The locking structure includes a locking member movably arranged, corresponding to the clamping portion, on the cover, and a second elastic member elastically abutting between the cover and the locking member. The locking member and the clamping portion can be disengaged by prodding the locking member, and thus the cover can be pressed so that the abutting member abuts against and closes the switch.

An atomizer and an electronic cigarette with an atomizer are disclosed. The atomizer includes an atomizer body, in which the atomizer body includes a shell, a suction nozzle assembly mounted at the top of the shell, a liquid chamber and an atomization core disposed in the shell. An electronic cigarette with the atomizer is disclosed as well. The electronic cigarette can prevent liquid accumulation caused by long-time static placement and various misoperations. Furthermore, cigarette liquid does not leak during injection. The components of the atomizer such as the suction nozzle or the base do not need to be disassembled, so that the cigarette liquid is convenient to inject, and the user experience is good.

A liquid storage assembly includes a liquid storage tube having a liquid storage chamber, a sealing member, an adjusting member, and a lower cover. The sealing member is received in the liquid storage tube and defines a second liquid intake hole fluidly communicating with the liquid storage chamber. The adjusting member is received in the liquid storage tube and is rotatable relative to the sealing member, the adjusting defines a communicating portion corresponding to the second liquid intake hole.

Certain aspects of present invention relate to an electronic cigarette having tamper-proof locking mechanisms. In certain embodiments, the electronic cigarette may include: an electronic cigarette body, a tamper-proof mouthpiece connector locking mechanism threadedly connected to electronic cigarette body, and a tamper-proof power connector locking mechanism threadedly connected to electronic cigarette body. When a user pushes tamper-proof mouthpiece connector locking mechanism towards electronic cigarette body, tamper-proof mouthpiece connector locking mechanism is locked such that the user is able to remove a mouthpiece connector from electronic cigarette body to refill e-liquid for the electronic cigarette. When user pushes tamper-proof power connector locking mechanism towards electronic cigarette body, tamper-proof power connector locking mechanism is locked such that user is able to remove a power connector from electronic cigarette body to replace a vaporizer, a heater for the vaporizer, and e-liquid storage medium of the electronic cigarette.

An atomizer includes a liquid storage assembly and a top cover assembly. The liquid storage assembly includes a liquid storage tube, a connecting seat fixed at one end of the liquid storage tube, and an operation ring movably disposed on the connecting seat. The operation ring is provided with resisting portions. The top cover assembly includes a top cover detachably connected to the connecting seat. The top cover is provided with teeth corresponding to the resisting portions. When the operation ring is moved to cause the resisting portions and the teeth to be mutually engaged/disengaged, a detachable connection between the top cover and the connecting seat is locked/unlocked. The atomizer is difficult to be disassembled by simple operation, and therefore has a children protection function.
