The cleaning water pump 7 includes a water pump body and a water tank. The water pump body is electrically connected to the controller and sprays cleaning liquid downward through the shower head 5 under the control of the controller.

[0033] A water inlet valve 71 connected to the water tank is disposed on the top of the cylinder cover 2, and the water inlet valve 71 is used to replenish the cleaning liquid in the water tank.

[0034] Specifically, the wiping mechanism 4 includes a plurality of lifting mechanisms vertically embedded in the bottom of the cylinder cover 2, and the bottom end of the lifting shaft of the lifting mechanism is sleeved with a wiping sleeve, and the wiping sleeve is adapted to the size of the clamping groove 31 and has a one-to-one correspondence in upper and lower positions.

[0035] The lifting mechanism drives the wiping sleeve to be inserted into the corresponding clamping groove 31 to wipe and clean the side wall.

[0036] An elastic clamping sleeve is provided around the inner wall of the clamping groove 31 to facilitate adapting to test tubes of different sizes. The elastic clamping sleeve may be made of rubber.

[0037] A drain valve 9 connected to the drain groove 32 is provided at the outer bottom of the cylinder 1 , and the drain valve 9 is used for discharging clean waste water in the drain groove 32 .
