Abstract: An electronic cigarette and a method for assembling the electronic cigarette are provided. The electronic cigarette includes an atomizer device mounting base, at least one conductive pipe, an atomizer device, and a battery device. The conductive pipe includes a first open end, a second open end, and a partition wall disposed within the middle of the conductive pipe to separate the first open end from the second open end. The atomizer device includes a first pluggable member being inserted into and electrically connected to the first open end. The battery device includes a second pluggable conductive member being inserted into and electrically connected to the second open end. When assembled, the atomizer device, the atomizer device mounting base, and the battery device can be connected together by employing an insertion method directly, thus the assembly process can be simplified, and the leakage of the liquid solution can be prevented.
