Abstract
A waterproof structure includes a shell which is provided with an air hole extending therethrough, a waterproof membrane is provided in a mounting cavity in the shell which abuts the inner side opening of the air hole, and the air hole is internally provided with a ball having waterproof performance and a constraint structure which constrains the ball in a preset range in the air hole; the preset range has a space allowing the ball to freely move; in a gas environment, there is gap between the ball and a boundary face of the present range, so as to allow the communication between the inner side opening and the outer side opening of the air hole; and the ball can press against the constraint structure under the pushing of liquid entering from the outer side opening and seal the inner side opening.
