Furthermore, the inner wall of the upper cover 2 is provided with four convex strips 23 which are uniformly distributed along the circumference of the axis of the upper cover 2, so that the upper cover is conveniently and closely matched with the connecting part 12.

Furthermore, four convex strips 23 and the exhaust port 22 are arranged in a staggered mode, and interference is prevented.

Further, the exhaust port 22 is arc-shaped, and has an attractive appearance.

Further, four lugs 21 which are uniformly distributed along the circumference of the axis of the upper cover 2 are arranged at the bottom of the inner cavity 24 of the upper cover 2, so that a certain gap is left between the plug body 1 and the upper cover 2 as a ventilation channel after the upper cover 2 is assembled.

Further, the upper cover 2 is made of hard plastic or metal material, and protects the waterproof breathable film 3 from being damaged by other external force.

Further, the installation part 11 and the connection part 12 are integrally formed by injection molding, so that the process is simple and the production is convenient.

Further, the plug body 1 is made of rubber materials, and the cost is low.

Further, the diameter of the waterproof breathable film 3 is the same as that of the connecting portion 12, so that the connecting surface between the waterproof breathable film 3 and the connecting portion 12 is the largest, and the connecting strength is increased.

The above is only a specific application example of the present invention, and the protection scope of the present invention is not limited in any way. All the technical solutions formed by equivalent transformation or equivalent replacement fall within the protection scope of the present invention.
