Abstract

Provided is an electronic cigarette comprising a smoking end, an atomization assembly and a battery assembly; an airflow passage communicating with the smoking end is defined in the electronic cigarette; one end of the battery assembly is provided with a first connection sleeve connected to the atomization assembly; a peripheral wall of the first connection sleeve is provided with at least one first air inlet hole; a side wall of a first accommodation chamber is provided with at least one second air inlet hole communicating with first accommodation chamber and the first air inlet hole; thus it is unnecessary for the airflow to pass through the electrode before entering the smoking end, such that a circulation of the air flow is smoother, noise is reduced, and the battery assembly and atomization assembly are prevented from being mixed up during use.
