Abstract
An electronic cigarette includes an electric locking device. When the atomizing assembly is energized, the electric locking device locks the cover; when the atomizing assembly is powered off and stops working, the electric locking device unlocks the cover. Or, the electronic cigarette includes a memory switch, when the temperature of the memory switch is greater than or equal to the transition temperature, the memory switch locks the cover. When the temperature of the memory switch is less than transition temperature, the memory switch unlocks the cover, thus improving the safety of the electronic cigarette.
Claims20
An electronic cigarette, comprising:
- a main housing;
- an atomizing assembly located in the main housing;
- and
- a cover attached to the atomizing assembly, wherein
- the electronic cigarette further comprises an electric locking device located between the main housing and the cover, and a control circuit board, when the atomizing assembly is energized, the control circuit board controls the locking member to lock the cover;
- when the atomizing assembly is powered off, the control circuit board controls the locking member to unlock the cover.
