ELECTRONIC CIGARETTE CHARGING AND DISCHARGING CIRCUIT, BATTERY ASSEMBLY AND ELECTRONIC CIGARETTE

摘要

The present application discloses an electronic cigarette charging and discharging circuit, wherein the electronic cigarette is provided with a charging input interface, such that the battery assembly can be directly inserted into a charger to be charged without removing the atomizing assembly, therefore the operation is more convenient, and wear and loose at the connecting portion caused by frequent disassembling and assembling can also be avoided. The present application further provides an electronic cigarette having the above charging structure and a battery assembly of the electronic cigarette. Besides being convenient for charging, the electronic cigarette may directly use a battery sleeve as an electrode, thus has a simple structure and is easy to manufacture.
