[0036] According to one aspect of the present application, a drainage device for compressed air tank is provided, comprising:

[0037] The drainage housing 1 is internally provided with a collecting cavity and a storage cavity which are in communication with each other, the separation layer 2 between the collecting cavity and the storage cavity is funnel-shaped so that the water inside the collecting cavity can better enter the inside of the storage cavity, the water inlet end is connected with the collecting cavity, and the water outlet end is connected with the storage cavity;

[0038] The first communication part 3 communicates the collecting cavity and the storage cavity;
