When the pressure applied to the pressing block 410 is removed, the water pump 200 is lowered below the water line 500 of the drawer tank 100. The linkage mechanism drives the water pump 200 to lift upwards through the pressing of the pressing block 410, so that the water pump 200 can be automatically lifted, the problem that the water pump 200 interferes with the extraction of the drawing water tank 100 is solved, and the operation process is concise and convenient when the drawing water tank 100 is taken out.

In operation, when water needs to be added to pull water tank 100, pressure is applied to pressing block 410, so that pressing block 410 is pressed down. After the pressing block 410 is pressed downwards, the pressing block 410 enables the lifting assembly to drive the water pump 200 to be lifted upwards to the upper side of the drawing water tank 100 through the linkage mechanism, then the drawing water tank 100 is drawn out of the accommodating cavity, and meanwhile the drawing water tank 100 cannot be interfered by the water pump 200 in the process of drawing out of the accommodating cavity.
