Abstract

An electronic cigarette comprises an electronic cigarette body which is provided with a smoking end, an oil reservoir, an atomization assembly, and a battery assembly. The oil reservoir is arranged at one end of the electronic cigarette body which is on an opposite side of the smoking end, and the atomization assembly is arranged in the oil reservoir, thus length of a whole electronic cigarette is shortened, and the electronic cigarette is portable. The oil reservoir is defined far away from the smoking end, so that a bad experience of sucking the tobacco tar by users can be effectively avoided. When smoking, the battery assembly close to the smoking end is held, and the oil reservoir is usually not supported by an external force, so that the oil reservoir outputs a uniform amount of the tobacco tar to the atomization assembly, and the stability of produced smoke is effectively ensured.
