The user can rotate second adjust knob 6a thereby it is rotatory to drive case 6c through second valve rod 6b, and case 6c is rotatory when making third through-hole 6c1 and fourth through-hole 6d1 communicate, and the inside clear water flow direction of clear water district is decontaminated and is dewatered the district, and the user rotates second adjust knob 6a once more and makes when third through-hole 6c1 and fourth through-hole 6d1 do not communicate, and clear water district and decontamination are dewatered the district and keep apart.

A flat mop cleaning method of a flat mop cleaning bucket comprises the following steps:

step one, injecting clean water into a clean water area: a user injects a certain amount of clean water into the clean water area through the water injection port 4a, and then lifts the cleaning barrel through the lifting handle 5 to move the cleaning barrel to an area to be cleaned;

step two, injecting clear water into the decontamination dehydration region: the user controls the valve component to open the water through hole, and the water through hole is closed by the control valve component after the clear water area injects a certain amount of clear water into the sewage-removing and dewatering area;

step three, adjusting the height of the sewage-cleaning wringing device; the user adjusts the height of the base 2a through the lifting mechanism 2e to enable the base to be lowered to the lowest position, then the user inserts the mop into the dirt cleaning and dewatering area through the base 2a, and then the height of the base 2a is adjusted through the lifting mechanism 2e to enable the base to move to the highest position of the mop or the stroke end point of the base 2 a;

step four, wetting the mop: a user holds the mop to be wetted by hands, inserts the mop into the dirt removing and dewatering area to wet the mop, and squeezes redundant moisture on the mop cloth into the sewage area by the water squeezing scraper 2b when the mop is pulled out;

step five, cleaning the mop: a user holds the mop to be cleaned by hand, inserts the mop into the decontamination and dehydration area and repeatedly pumps and inserts the mop, the mop is washed by clean water in the decontamination and dehydration area, sewage on the mop is squeezed into the sewage area through the water squeezing scraper 2b, dirt on the mop is scraped by the sawtooth scraper 2c and enters the sewage area along with the sewage, and the mop is stopped until the water level in the decontamination and dehydration area is lowered below the upper bottom 1a 2;

step six, injecting clean water into the decontamination and dehydration area again: repeating the second step until the water level in the sewage-removing and dewatering area is level to the water level in the clean water area;

step seven, cleaning the mop again: a user holds the mop cleaned for the first time, rotates or turns over the mop cloth part by 180 degrees, so that the downward end of the mop cloth part in the fourth step is arranged upward, and then repeats the fourth step;

step eight, dumping sewage: a user holds the handle 5 and then inclines the barrel body 1, and residual sewage in the barrel body 1 is poured out through the water injection port 4a, the mop port 4b, the water outlet 4c and the overflow groove 4 e;

step nine, cleaning the barrel body: the user pulls the plug 1f out of the rubber ring 1e, then places the water outlet 4c below the faucet, and cleans the residual dirt inside the sewage area by running water.

The working principle of the invention is as follows:

a user injects a certain amount of clean water into the clean water area through the water injection port 4a, and then the clean water enters the decontamination and dehydration area by opening the limber hole through the control valve component; after the decontamination and dehydration area stores a certain amount of clear water, a user inserts the mop into the decontamination and dehydration area through the decontamination and water squeezing device 2 and repeatedly pumps and inserts the mop, the mop is washed by the clear water in the decontamination and dehydration area, and dirt and sewage on the mop are scraped by the decontamination and water squeezing device 2 and enter the sewage area; the user can also rotate the mop head by 180 degrees, so that the two ends of the mop head are cleaned evenly; after repeated pumping and inserting, sewage in the sewage-removing and dewatering area continuously enters the sewage area through the sewage-removing and water-squeezing device 2, so that the water level in the sewage-removing and dewatering area is lowered to the position below the top end of the bed-up area; at the moment, the water level at the lowest position of the clean water area is higher than the water level of the sewage disposal dehydration area, then a user opens the water through hole through the control valve component, water in the clean water area flows into the sewage disposal dehydration area through the water through hole, and the water level of the clean water area is always higher than the water level of the sewage disposal dehydration area, so that sewage in the sewage disposal dehydration area cannot flow back to the interior of the clean water area; when sufficient clear water is injected into the dirt removing and dewatering area, the water through hole can be closed through the control valve assembly without waiting for the water level balance of the clear water area and the dirt removing and dewatering area, and then the mop is cleaned again; after cleaning, the handle 5 is lifted to rotate the barrel body 1, so that sewage can be poured out through the water outlet 4c and the overflow groove 4e, then the water outlet 4c is arranged below the water faucet, and the plug 1f is pulled out, so that residual dirt in a sewage area can be cleaned through flowing water.
