[0075] The mop has various specific structures. For example, one scheme is that the first rod body 38 is used as a mop rod for holding operation, the second rod body 35 is sleeved outside the first rod body 38 as a sleeve, and the second rod body 35 is coaxial with the first rod body 38. The second rod body 35 can slide up and down along the first rod body 38. When the flat mop head 42 is turned to be parallel to the first rod body 38, the flat mop head 42 can be inserted into the wrung 40. When the second rod body 35 moves to the high position with the wrung head 39, the flat mop head 42 is separated from the wrung 40. When the second rod body 35 moves to the low position with the wrung head 39, the lower end of the flat mop head 42 is inserted into the wrung 40. The second rod body 35 is pulled upward through the wrung 40 to squeeze water on the wiping part of the flat mop head 42.

[0076] Figure 11 Another scheme is shown in the figure. The first rod body 38 is parallel to and different from the second rod body 35. The intermediate connecting piece 36 is arranged between the first rod body 38 and the second rod body 35. The second rod body 35 passes through the intermediate connecting piece 36 and can move up and down on a straight line relative to the intermediate connecting piece 36. The intermediate connecting piece 36 is provided with a transversely extending part 37. The upper end of the first rod body 38 is fixed to the transversely extending part 37.

The first rod body 38 is located on one side of the top of the flat mop head 42.

[0077] Figures 19-25 As shown in the figure, the mop bucket 1 is provided with a clean water area 20 for containing clean water and a cleaning area 7 for containing the mop. The flat mop head 42 is vertically inserted into the cleaning area 7, and the wrung head 39 is sleeved outside the flat mop head 42. The mop bucket 1 is provided with a water pumping mechanism for pumping water to the mop. The water pumping mechanism includes a pump body 21 and a piston part 22. The pump body 21 is provided with a piston cavity 19. The piston part 22 is slidably arranged in the piston cavity 19. The piston part 22 is fixedly provided with a piston rod 16. The piston rod 16 is provided with a matching part 9 located in the cleaning area 7 and matched with the water squeezing frame 44. A connecting assembly is arranged between the matching part 9 and the water squeezing frame 44. The connecting assembly is detachably connected with the matching part 9 and the water squeezing frame 44. In the process of the water squeezing frame 44 being pushed and pulled upward and downward by external force, the matching part 9 is driven to move upward and downward, so that the piston rod 16 drives the piston part 22 to slide upward and downward in the piston cavity 19. The water pumping mechanism pumps the water in the clean water area 20 and sends it to the cleaning area 7 for cleaning the mop.

[0078] The patent cleaning process is realized by the cooperation between the squeezing frame 44 and the cooperation part 9, so that the piston part 22 slides up and down in the piston cavity 19. Once the squeezing frame 44 moves up and down, the water supply mechanism supplies water once. The squeezing part 41 on the comb head 39 squeezes water on the flat mop head 42 during the up and down movement, so that the flat mop head 42 is cleaned and squeezed once. The water supply mechanism does not supply water continuously during the whole cleaning process. The water supply mechanism supplies water in cooperation with the up and down movement of the squeezing frame 44, and does not need to manually open and close the water supply device, so it is not easy to cause excessive water use and waste. The water supply mechanism supplies water once, and the mop is cleaned and dehydrated once, which improves the cleaning efficiency of the mop. The flat mop head 42 is placed in the mop bucket 1 for cleaning. During the cleaning process, the sewage is blocked by the bucket wall and is not easy to splash on the cleaner or the surrounding ground, which is more clean and sanitary.

[0080] The upper and lower sides of the part where the second locking piece 51 and the second locking groove 54 are clamped and matched are provided with inclined surfaces or arc surfaces 47 for guiding. When the comb head 39 is inserted or pulled out of the positioning column 50 under a relatively large external force, the inclined surface or arc surface 47 is in contact with the comb head 39 to extrude and make the second locking piece 51 overcome the elastic force of the second supporting spring 52 and shrink into the cooperation part 9, so that the comb head 39 can be inserted on the positioning column 50 to be locked or unlocked and separated from the positioning column 50.

[0091] Figure 23 , Figure 24 As shown, the working principle is as follows: the cleaner pushes down the second rod 35 to move the brush head 39 downwards. During the downward movement of the brush head 39, the mating part 9 moves downwards simultaneously, causing the piston rod 16 to drive the piston part 22 downwards. When the piston part 22 moves downwards, the volume of the water suction chamber 27 decreases, creating positive pressure inside the water suction chamber 27. The water in the water suction chamber 27 pushes the second ball valve upwards to open the water inlet opening of the water outlet pipe 28. At the same time, the first ball valve is closed by the pressure inside the pump body 21 against the water inlet opening of the water inlet pipe 31. The water in the water suction chamber 27 enters from the lower opening of the water outlet pipe 28, passes through the water outlet channel, the water outlet pipe 28, and the water supply pipe 25, and is then transported to the water holding section 23. The water in the water holding section 23 is sprayed onto the cleaning area from the spray nozzle 6. The flat mop head 42 is placed inside the 7. Then, the cleaner lifts the second rod 35 to move the brush head 39 upward. During the upward movement of the brush head 39, the squeezing part 41 at the brush opening 40 squeezes water from the wiping part of the flat mop head 42. At the same time, the brush head 39 drives the mating part 9 to move upward in sync. When the piston part 22 moves upward, the volume of the water suction chamber 27 increases, and a negative pressure is formed in the water suction chamber 27. The water in the clean water zone 20 pushes the first ball valve upward to open the water inlet end opening of the water inlet pipe 31. At the same time, the second ball valve is pressed tightly against the water inlet end opening of the water outlet pipe 28 by the external air pressure to form a seal. The water in the clean water zone 20 enters from the lower opening of the water inlet pipe 31, passes through the water inlet channel and the water inlet pipe 31, and is drawn into the water suction chamber 27 to prepare for the next water output.

[0092] Figures 23-26 As shown, the cleaning area 7 is equipped with a first support 14 and a second support 15 for supporting the flat mop head 42. The second support 15 is higher than the first support 14. When the flat mop head 42 is supported on the first support 14, the wringer 44 is opposite to the mating part 9. During the up-and-down movement of the wringer 44, the mating part 9 moves synchronously, and the mop performs dehydration and washing during this process. When the flat mop head 42 is supported on the second support 15, the wringer 44 and the mating part 9 are separated. During the up-and-down movement of the wringer 44, the mating part 9 stops moving, and the water pumping mechanism does not supply water to the mop; the mop only performs dehydration. By setting two positions, the mop can achieve both washing and dehydration states. The second support 15 is higher than the first support 14, which makes it less likely for the mop to come into contact with sewage in the cleaning area 7 during dehydration, thus avoiding secondary pollution.
