Aroma diffuser

An aroma diffuser, comprising an atomization mechanism, wherein

• the atomization mechanism comprises an atomization shell and an essential oil bottle, the essential oil bottle is provided with a first cavity, and the atomization shell is provided with a second cavity;
• the essential oil bottle and the atomization shell are connected in sequence from bottom to top, so that the first cavity and the second cavity communicate with each other;
• the atomization mechanism further comprises a leakage-proof cover, an elastic body and a ball;
• at the atomization shell is formed a leakage-proof accommodation cavity, at the leakage-proof accommodation cavity is provided a first communication hole communicated to the first cavity, at the leakage-proof cover is provided a second communication hole, and the anti-leakage cover shell is closed at an upper opening portion of the leakage-proof accommodation cavity so as to communicate the second communication hole to the second cavity;
• the elastic body and the ball are arranged inside the leakage-proof accommodation cavity and the leakage-proof cover from bottom to top, an end of the elastic body abuts against an inner wall of the leakage-proof accommodation cavity, and another end of the elastic body abuts against the ball;
• and
• when the atomization mechanism is placed normally, pressure exerted by the ball on a spring compresses the spring to make the second communication hole of the leakage-proof cover open;
• when the atomization mechanism is tilted, pressure exerted by the ball on the spring is not sufficient to compress the spring, and the spring stretches to make the ball abut against at least a portion of the leakage-proof cover, so that the second communication hole of the leakage-proof cover is closed.
