A water tank opening communicated with the tail end of the flow channel (8) is formed in the middle of the water tank (9), and the initial end of the flow channel (8) is connected to a water supply device. Under the condition that the number of the spray heads (10) is the same and other related parameters are unchanged, the water tank opening is formed in the center, and the effect of spraying cleaning liquid to the cleaning component (6) is better than the effect of spraying cleaning liquid from two sides and the one-third position.
