After the cleaning is finished, the driving motor 47 drives the mop disk 43 to reversely rotate, the mop disk 43 drives the driven support member 9 to reversely rotate, at the moment, the first one-way bearing 27 breaks the transmission between the driven support member 9 and the fixed shaft 24, the second one-way bearing 30 breaks the transmission between the fixed shaft 24 and the toothed driving member 18, so that the driven support member 9, the fixed shaft 24 and the toothed driving member 18 can relatively rotate, the toothed driving member 18 does not rotate along with the driven support member 9, the fluted disc 39 does not rotate, the rocker 37 stops driving the piston 17 to reciprocate in a linear manner, the piston 17 does not pump clean water into the pump body 32, the pump body 32 does not convey clean water to the drain pipe 34, and the mop disk 43 rotates and spin-dries water on the wiper 48.

When the mop disk 43 rotates, water dropped on the mop disk 43 and water thrown out can outwards flow into the waste water accommodating cavity 2 along the upper cover plate 5, a waste water discharge port 4 is arranged at the bottom of the mop bucket, the waste water discharge port 4 is communicated with the waste water accommodating cavity 2, and waste water in the waste water accommodating cavity 2 is discharged from the waste water discharge port 4.

As shown in the drawing, when the double-ended mop is cleaned, the mop has two mop plates 43, the top of the driven support member 9 is supported below one of the mop plates 43, and the mop plates 43 are driven to rotate, the upper cover plate 5 is provided with a support lug 7 corresponding to the other mop plate 43, the support lug 7 is in a cylindrical structure, the support lug 7 is inserted into a transmission groove 49 at the bottom of the corresponding mop plate 43, the support lug 7 is supported below the corresponding mop plate 43, the mop plates 43 can rotate relative to the support lug 7, the waterway 36 extends to the lower part of each mop plate 43, and the waterway 36 below each mop plate 43 is provided with a purified water outlet 8 for cleaning the mop plate 43.

The one-way bearing is a bearing structure existing in the market, and is a bearing which can freely rotate in one direction and is locked in the other direction, and is also called an overrunning clutch. Such as a one-way bearing of the brand PNY, model CSK8 PP.
