Electronic cigarette

Abstract

An electronic cigarette including an atomization assembly and a battery assembly. The battery assembly comprises an overtime work protection unit. The overtime work protection unit comprises a control panel; when the electronic cigarette works continuously for over a preset time limit in a single puffing period, the overtime work protection unit automatically shuts off a power supply to the control panel.

What is claimed is: 
     
         1 . An electronic cigarette, comprising: an atomization assembly and a battery assembly; the battery assembly comprising an overtime work protection unit; wherein:
 the overtime work protection unit comprises a control panel; when the electronic cigarette works continuously for over a preset time limit in a single puffing period, the overtime work protection unit automatically shuts off a power supply to the control panel.   
     
     
         2 . The electronic cigarette of  claim 1 , wherein the set time limit is 10 seconds. 
     
     
         3 . The electronic cigarette of  claim 2 , wherein the overtime work protection unit further comprises a spring contact and a battery; an output end of the battery is connected to an input end of the control panel; an output end of the control panel is connected to the spring contact to supply power for the atomization assembly; the spring contact is connected to an input end of the atomization assembly; the control panel comprises a pneumatic switch activatable by vapor to trigger the control panel to output a voltage to the atomization assembly; when a continuous activation time of the pneumatic switch exceeds 10 seconds, the overtime work protection unit automatically shuts off the power supply to the control panel. 
     
     
         4 . The electronic cigarette of  claim 3 , wherein when the overtime work protection unit is driven to touch the atomization assembly, a closed loop circuit is formed thereby lighting up an LED light disposed on the control panel. 
     
     
         5 . The electronic cigarette of  claim 1 , wherein the atomization assembly is disposed on the battery assembly; the atomization assembly comprises a magnet and the battery assembly comprises a stainless iron adsorbing on the magnet.
