Abstract

The invention relates to a battery rod and an electronic cigarette. The battery rod comprises a battery casing, a battery, a control module, and an end cover. Wires and an airflow sensor are provided on the control module. An elastic mounting base is provided within the battery casing. The elastic mounting base is provided with a through hole running along the axial direction. The control module is installed in the through hole of the elastic mounting base. An inner peripheral surface of the elastic mounting base elastically abuts against an outer peripheral surface of the control module. The wires penetrate the through hole and parts of the wires are compressed between the control module and the elastic mounting base. Compared to the prior art wherein wires pass through separate holes, the invention has a simple assembly means, reduces the product defect rate, and improves the sensitivity of the electronic cigarette.
