Electronic cigarette

Abstract

An electronic cigarette is provided, which comprises an atomizer, and a first electrode and a second electrode which are inserted in an end portion of the atomizer; wherein the atomizer is further provided therein with an atomizing element for atomizing tobacco tar, and a first lead wire and second lead wire which are electrically connected to the atomizing element; the second electrode has an extension part that extends into the interior of the atomizer; the second lead wire is electrically connected to the extension part, and the first lead wire is electrically connected to the first electrode. At least one first through-hole allowing airflow to pass through is defined on a side face of the extension part. In the electronic cigarette, a clogging phenomenon is not easy to occur when the second lead wire is electrically connected to the second electrode by means of soldering.
