In some other embodiments, the water outlet is formed between the upper end of the outer cylinder and the periphery of the upper end of the inner cylinder.

The lower end of the supporting part is connected with a connecting piece 312, and the lower end of the connecting piece 312 is fixedly connected with the upper end of the inner cylinder body in an inserting manner.

In this embodiment, the flow blocking portion and the second water wheel are centrifugal water wheels. In other embodiments, the flow blocking part and the second water wheel may also be axial flow water wheels, and of course, the flow blocking part may also adopt a hollow cavity structure provided with through holes; when the water pumping mechanism is driven by the mop to rotate, the flow blocking part generates downward driving force to water, and the second water wheel generates upward driving force to water.

It should be noted that, when the mop drives the rotating component to rotate and the rotating component is accelerated from the first rotating speed to the second rotating speed, a critical rotating speed exists, and when the rotating component reaches the critical rotating speed, water around the water inlet is driven away by the flow blocking part and cannot enter the inside of the water pumping mechanism, so that no water is sprayed out from the water outlet. It should be noted that the critical rotation speed is positively correlated with the water level in the mop bucket, i.e. the higher the water level in the mop bucket is, the larger the critical rotation speed is. When the rotary driving mechanism is a hand-press type rotary mop rod, the user cannot determine the second rotating speed when using the mop barrel for spin-drying the mop for the first time, but as long as the user feels that the humidity of the wiping object is high, the force for pressing the hand-press type rotary mop rod is properly increased during spin-drying, so that the rotating speed of the mop head is improved. The first rotation speed and the second rotation speed are relative values and are not fixed values determined by numerical values. It should be noted that when the second rotation speed is close to the critical rotation speed, a small amount of water enters the inside of the water pumping mechanism from the water inlet, that is, a small amount of water is sprayed from the water outlet, but as long as the amount of water spun by the wipe per unit time is larger than the amount of water sprayed by the water outlet, the wipe is still in a normal spin-drying state, and the spin-drying of the wipe is not significantly affected.

When the mop is used, the mop is placed into the mop bucket as shown in figure 1, the mop head is connected with the supporting part, the mop head is rotated by pressing the hand-press type rotating mop rod, so that the water pumping mechanism is driven to rotate, when the water pumping mechanism rotates at a first rotating speed (lower than a critical rotating speed), as shown in figure 9, a part of water near the water inlet is discharged by the flow blocking part, a part of water enters the water pumping mechanism from the water inlet, flows along the upper water channel under the driving of the second water wheel and is sprayed out from the water outlet to moisten the wiper, and in the process that the wiper is contacted with the brush and moves relatively, dirt carried on the wiper and adsorbed water are scraped by the brush, and simultaneously, the wiper is thrown to the inner wall of the mop bucket under the action of centrifugal force and finally falls into a sewage area.

After the hand-press type rotating mop rod is pressed for 5-20 times (whether the water thrown to the inner wall of the mop barrel does not contain dirt can be judged by visual inspection to approximately judge whether the water is continuously pressed or not), then the pressing frequency and/or the pressing force are accelerated, the water pumping mechanism is pressed for 5-20 times to rotate at a second rotating speed (namely, the rotating speed is greater than the critical rotating speed), at the moment, as shown in figure 10, the water close to the water inlet is driven by the flow blocking part to be discharged outwards, no water or only a small amount of water enters the water pumping mechanism through the water inlet, the second water wheel idles, no water is sprayed out from the water outlet, the wiper is gradually dried, and a user can adjust the pressing frequency according to actual needs to flexibly control the dryness and humidity.
