Return airflow atomizer and electronic cigarette comprising atomizer

Abstract

The invention provides a return airflow atomizer and an electronic cigarette. The return airflow atomizer comprises a sucker, a top external thread, a ventilating valve, a ventilating thread, a damping ring, an air guide pipe, a ventilating pipe, a bottom internal thread, springs and steel positioning balls, wherein the top external thread is connected with the ventilating thread; the springs are arranged in the top external thread; the steel positioning balls are arranged outside the springs; the ventilating valve is used for fixing the springs and the steel positioning balls; a plurality of ventilating holes are formed in the ventilating valve, and the ventilating valve sleeves the outer wall of the top external thread in a clamping manner; when rotating left and right by 360 degrees, the ventilating valve is positioned by the springs and the steel positioning balls; when the ventilating holes in the ventilating valve are communicated with air holes formed in the top external thread, airflow enters the ventilating thread. The electronic cigarette comprises the return airflow atomizer. Compared with the conventional atomizer in which the airflow enters from the bottom and leaves from the top, the return airflow atomizer disclosed by the invention is an atomizer which works by virtue of a top air inlet mode and a top air outlet mode under internal airflow circulation.

Description

technical field [0001] The invention relates to the field of electronic cigarette design, in particular to an electronic cigarette with oil filling in the upper part and air intake in the upper part. Background technique [0002] E-cigarette is a non-combustible cigarette substitute, and it is a new type of electronic product. It senses the change of airflow through the airflow sensor, thereby controlling the corresponding circuit function, atomizing the e-liquid to form smoke, so as to achieve It has the same effect as when smoking real cigarettes, but without the tar and other harmful substances of cigarettes. [0003] The atomizer is the main part of the electronic cigarette. Most of the existing electronic cigarette atomizers are used for repeated oil injection. There are two oil injection methods: one is the structure that the heating wire is placed at the bottom of the atomizer, and the air intake hole is at the bottom. , When filling oil, you need to turn the atomize...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to solve the problem of oil leakage easily caused by the electronic atomizer in the process of refilling oil and to break through the traditional air intake method
