Electronic cigarette and battery assembly thereof
View Patent ↗The present application provides an electrical cigarette and a battery assembly thereof, wherein a first charging electrode assembly is arranged at a front end of the battery assembly, such that the battery assembly can be directly inserted into a charger to be charged without removing an atomizing assembly, therefore the operation is more convenient and disadvantages caused by frequent disassembling and assembling may be avoided. In addition, under the action of a charging management circuit, the electrode assembly at the front end can only be charged but cannot discharge, thereby avoiding an occurrence of a short circuit when the charging terminal discharges, extending the service life of the battery, and further avoiding a hidden danger of battery liquid leakage caused by the short circuit. In addition, since the front end of the electronic cigarette can not discharge, a situation that the electronic cigarette still has a low battery even been charged for a long time will not happen.
