Background technique

E-cigarette is a non-combustible smoke substitute. It is a new type of electronic product that senses the change of airflow through the airflow sensor, thereby controlling the corresponding circuit function, atomizing the smoke oil to form smoke, thus achieving image The effect of smoking a real cigarette, but there is no harmful substance such as tar of cigarettes.

The atomizer is the main component of the electronic cigarette. The existing electronic cigarette atomizers are mostly used for repeated oil injection. There are two types of oil injection: one is to set the heating wire at the bottom of the atomizer, and the air inlet is at the bottom. When filling the oil, the atomizer should be inverted, the internal atomizing core and the bottom threaded part should be screwed down, and then the oil is injected. This way, the residual oil of the atomizer can be easily brought out, which causes waste of waste oil and unnecessary. The trouble, at the same time, if the atomizer is not used for a long time, it will leak oil; the other is to unscrew the nozzle or other sealing parts, also the bottom air intake, also from the top of the atomizer Oil filling, but this structure, if filled with oil, if it is not sealed in time, the atomizer will leak oil due to air pressure, which will bring great trouble to the use.
