[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model uses the elasticity of a spring on the slide tube, which allows the slide tube to slide outside the air outlet pipe. This makes it less likely for water to enter the slide tube, while allowing it to slide relative to the outer shell, thus avoiding interference with the movement of objects.

[0012] 2. This utility model uses the elastic action of a compression spring on the sealing ring, which allows the sealing ring to separate from the retaining ring, preventing air from escaping between the outer shell and the vent pipe after water ingress, thus preventing water from splashing.
