Abstract

The present disclosure provides an atomization device including a liquid storage cavity, a liquid injection opening, and an injection structure; the injection structure includes an injection tube and a sealing member; the injection tube runs through the liquid injection opening and extends into the liquid storage cavity, and a liquid inlet is formed in a side wall of the injection tube; the sealing member is arranged on one end of the injection tube in the liquid storage cavity; the sealing member is sealed from an inner wall of the liquid storage cavity, and separates the liquid inlet from the liquid storage cavity. When the injection tube is pushed into the liquid storage cavity, the liquid inlet moves into the liquid injection opening to communicate with the liquid storage cavity. When the injection tube is not pushed, the injection tube separates the liquid inlet from the liquid storage cavity.
