Beschreibung
Zusammenfassung:	The utility model relates to the technical field of power adapters, in particular to a waterproof and moistureproof power adapter, which comprises a shell, the upper surface and the lower surface of the shell are concave, an opening is arranged in the middle of the inner bottom surface of the concave part of the upper surface of the shell, and a miniature air pump is clamped and mounted on the inner surface of the opening of the shell. Ventilation holes are formed in the four corners of the inner bottom face of the inwards-concave part of the upper surface of the shell, a first sealing cover is arranged on the shell through an opening of the inwards-concave part of the upper surface, an opening is formed in the middle of the upper surface of the first sealing cover, and a plugging nut is inserted into the first sealing cover through the inner surface of the opening. The device is reasonable in design, the waterproof effect can be achieved by improving the sealing performance, meanwhile, moisture in the power
