Abstract

A battery rod and an electronic cigarette are provided. The batter rod includes a battery cartridge, a battery accommodated in the battery cartridge, and a connection unit inserted at one end of the battery cartridge and for connecting with an atomizer. A charging assembly used to electronically connecting with a charger is inserted at one end of the battery cartridge away from the connection unit, and includes an internal electrode, an insulation holder inserted inside the battery cartridge, an insulation ring and an external electrode. The insulation ring is sleeved on an outer circumferential surface of the internal electrode. The external electrode is sleeved on an outer circumferential surface of the insulation ring. The internal electrode and the external electrode are electronically connected to two electrodes of the battery, respectively.

First claim
