The utility model discloses a liquid discharge device which comprises a liquid pipe and an air pipe, the first end of the liquid pipe extends into a liquid collecting tank and is located below the liquid level, the first end of the air pipe extends into the liquid collecting tank and is communicated with the first end of the liquid pipe, and a communication hole is further formed in the communication position of the air pipe and the liquid pipe. During use, one end, communicated with the air pipe, of the liquid pipe extends below the liquid level of the liquid collecting tank so as to ensure that the communicating hole is communicated with liquid in the liquid collecting tank, then an external air source conveys air into the air pipe from the second end of the air pipe, the air penetrates through the air pipe and enters the liquid pipe, the liquid near the communicating hole forms a low-pressure area, and under the action of negative pressure, the liquid in the liquid collecting tank is separated from the air
