Abstract

An electronic cigarette is provided, which can prevent users being short of breath and a short circuit of a battery assembly. When the atomizer assembly is connected to the battery assembly, the first elastic electrode column and the second elastic electrode column abut against the annular end surface of the outer electrode and the annular end surface of the inner electrode, respectively, and the first elastic electrode column and the second elastic electrode column are both deviated from the opening of the hollow cavity of the inner electrode of the atomizer assembly. Thus, a manner of point-surface contact and deviating from the opening of the cavity is formed, which not only ensures an unobstructed air passage and prevents users being short of breath.
