Abstract: An electronic cigarette has a conduit arranged in a atomizing stem, the conduit has a first segment and a second segment in communication with the first segment, the first segment has a wider inner space than the inner space of the second segment; a storage chamber is outside and surrounds the conduit; and a heating device arranged inside the inner space of the first segment of the conduit for atomizing an atomizable material coming from the storage chamber.
