Description

Electronic cigarette atomizer for solid e-liquid

Technical field

The present invention relates to the technical field of electronic cigarette atomizers. More specifically, the present invention relates to an electronic cigarette atomizer for solid e-liquid.

Background technique

E-cigarettes generally include interconnected battery components and atomizers. The battery components are equipped with batteries that supply power to the atomizer. E-cigarette atomizers generally include heating components. When the heating components work, they can evaporate liquid e-cigarette oil. Evaporates into e-cigarette mist or aerosol for users to inhale and inhale. Since liquid e-cigarette oil is prone to leakage during transportation, storage and use, e-cigarettes using paste-like solid e-cigarette oil are gradually appearing on the market.

The structure of the existing electronic cigarette atomizer using solid e-liquid usually uses a heating plate type heating component. The atomization chamber and the oil storage chamber of the heating component are integrated. That is, the smoke generated after the solid e-liquid is heated still comes from the oil storage chamber. It is discharged from the cavity, so that the e-liquid that melts more during high-temperature atomization will easily leak from the smoke discharge port. There is also a method on the market that uses electric heating wires to directly heat solid e-liquid. In this method, the heating wire heats the solid e-liquid and melts it, turning it into liquid e-liquid. The liquid e-liquid is prone to dripping. In addition, after a period of use of the solid e-liquid in the oil storage chamber, the side of the solid e-liquid in contact with the heating wire is consumed. Without the action of external force, the solid e-liquid gradually breaks away from the heating wire, which may easily cause atomization in the future. Poor and dry burning problems occur.
