As shown in fig. 1 to 3, the embodiment of the present invention provides a drainage device, which includes an air pressure box 1 and a vacuum pump 2. The air pressure box 1 is in a cuboid shape, and a cavity is arranged in the air pressure box and used for storing water. The air pressure box 1 is provided with an air suction port 13, a water pumping port 15 and a water discharge port 16.

The air suction port 13 is connected with the vacuum pump 2, and when the vacuum pump 2 works, air is sucked from the air pressure box 1, so that the cavity of the air pressure box 1 is in a negative pressure state.

The water pumping port 15 is connected with a water channel structure of the wall-mounted air conditioner through a water pumping pipe 6. The water channel structure is used for being arranged below an evaporator of the wall-mounted air conditioner, and condensed water is generated when the evaporator works and can drip into the water channel structure.
