AI Technical Summary

Technical Problem

The existing design of separating the e-liquid tank from the atomizer core has problems such as poor oil blocking effect of the oil storage cotton, cumbersome operation of the oil blocking plug that requires manual operation, and the influence of the placement method, which makes the e-liquid prone to leakage.

Method used

The screw driven by a motor works in conjunction with the oil valve. The motor is controlled by a control circuit board, which raises and lowers the oil valve to automatically open and close the oil tank and the atomization channel, avoiding manual operation and ensuring the sealing effect of the oil tank.

Benefits of technology

It enables automatic opening and closing of the e-liquid tank, reducing the difficulty of operation, avoiding oil leakage problems, and ensuring that the e-liquid in the tank can be used as needed and that the atomization channel can be disconnected.

Abstract

An electronic cigarette capable of automatically opening and closing an oil tank comprises a shell, an atomization assembly, a control assembly and an opening and closing assembly. The top of the shell is provided with a suction port. The upper part of the inner cavity of the shell is provided with an oil tank and an air outlet channel communicating with the suction port. The lower part of the inner cavity of the shell is provided with an atomization channel communicating with the air outlet channel, an air inlet hole penetrating through the shell and communicating with the atomization channel, a driving cavity sealed and separated from the atomization channel and the oil tank, and an adjusting cavity communicating with the atomization channel and the oil tank. The communicating part of the adjusting cavity and the oil tank forms a first channel, and the communicating part of the adjusting cavity and the atomization channel forms a second channel. The atomization assembly comprises an atomization core. The control assembly comprises a control circuit board and a battery. The opening and closing assembly comprises a motor located in the adjusting cavity, a screw rod fixed on the output shaft of the motor, and an oil valve threadedly connected with the screw rod and provided with an oil guide hole. The oil guide hole communicates with the first channel and the second channel when the oil valve is lifted to guide the oil tank and the atomization channel, and is staggered with the first channel and / or the second channel to separate the oil tank and the atomization channel.
