The water discharge control structure further comprises a water storage tank 3 connected to the washing bucket body 1, wherein the water storage tank 3 has a water outlet 21 directing to the cleaning tool, and the discharge of water of the water outlet 21 is controlled by a plug 64; when the lifting frame 4 is in a high position, the lifting frame 4 drives the plug 64 in a linked manner to block the water outlet 21; when the lifting frame 4 is in a low position, the lifting frame 4 drives the plug 64 in a linked manner to open the water outlet 21 to allow water to flow to the cleaning tool from the water outlet 21.

[0030] Furthermore, at least one scrubbing base 2 is arranged in the washing bucket body 1. Preferably, the scrubbing bases 2 are suspended in the washing bucket body 1, a gap is formed between the scrubbing bases 2 and the bottom of the washing bucket body 1 and is used for storing dirty water, the water outlets 21 are sequentially formed in upper sides of the scrubbing bases 2, the scrubbing bases 2 are circumferentially and regularly distributed with the center axis of the lifting frame 4 as the center and are each of a strip shape, two parallel rows of bristles 22 are sequentially arranged on the upper side of each scrubbing base 2, and the water outlets 21 are sequentially and regularly distributed between the two rows of bristles 22 in an axial direction. Wherein, an inflow passage 61 which extends in the axial direction and is communicated with the water outlet 21 is formed in the scrubbing base 2, a discharge joint 62 is arranged at the lower end of the water storage tank 3, a discharge passage 63 communicated with the inflow passage 61 is formed in the discharge joint 62, the plug 64 is arranged between the discharge passage 63 and the inflow passage 61, an elastic ejection structure connected to one end of the plug 64 is arranged in the discharge joint 62, and a plug ejection assembly 6 enabling the plug 64 to move in the axial direction, when the lifting frame is vertically lifted or lowered, is arranged between the other end of the plug 64 and the lifting frame 4.
