The squeezer is a squeezing sheet or a squeezing roller, and the squeezer is fixedly connected or rotatably connected or slidably connected to the cover body. The barrel body or/and the cover body are also connected with a handle 11.

The flat mop is shown in fig. 7 and comprises a mop plate 7 and a mop rod 8, the bottom surface of the mop plate 7 is connected with a wiping object 72, the lower end of the mop rod 8 is connected with the middle position of the mop plate through a rotating joint 73, the rotating joint is rotatably connected with the mop rod and the mop plate, and the two rotating shafts are vertical. When the mop plate is rotated to be approximately parallel to the mop rod in the state shown in fig. 7, the flat mop is in a cleaning state.

The barrel body is provided with a large water storage area 3a, a small water storage area 3b and a mop cleaning area 102, and the mop cleaning area is positioned under the mop cleaning opening 21. A water filling opening 22 is arranged on the cover body corresponding to the large water storage area.

The capacity of the small water storage area is smaller than that of the large water storage area, in this embodiment, the capacity of the large water storage area is designed to be 5-10 times of that of the small water storage area, and the capacity of the small water storage area is 200-. And at least one communication hole 311 is provided between the large water storage area and the small water storage area, and water located in the large water storage area can be injected into the small water storage area through the communication hole.

In this embodiment, be equipped with first baffle 10 in the staving, first baffle separates the staving for mop clean area 102 and sewage water storage district 101, demountable installation has interior staving in the mop clean area, interior staving upper portion is big water storage district 3a, little water storage district 3b body coupling is in big water storage district lower extreme.

In other embodiments, a second partition plate is further arranged in the barrel body, and the first partition plate and the second partition plate divide the barrel body into a water storage area, a mop cleaning area and a sewage storage area in sequence; the upper part of the water storage area is the large water storage area, and the lower part of the water storage area is the small water storage area.

The mop cleaning port or mop cleaning area is provided with a water spraying member for spraying water toward the flat mop, in this embodiment, the water spraying member is a plurality of water spraying ports 202 horizontally arranged toward the mop cleaning port, and in other embodiments, the water spraying member may be one or more elongated openings horizontally arranged. A first water pumping device 5a and a second water pumping device 5b are arranged in the barrel body.

The water inlet ends of the first water pumping device and the second water pumping device are both communicated with the small water storage area, and the water outlet end of the first water pumping device is communicated with the water spraying part, namely the first water pumping device is used for conveying water to the flat mop to clean the flat mop; the water outlet end of the second water pumping device is communicated with the large water storage area, namely the second water pumping device is used for discharging water flowing into the small water storage area from the communication hole 311 in real time, so that the water level in the small water storage area does not rise at least in the process that the mop plate moves up and down in the mop cleaning opening.

Preferably, the water inlet end of the first water pumping device is higher than the water inlet end of the second water pumping device.

When the first water pumping device and the second water pumping device are in continuous working states, the second water pumping device pumps water from the small water storage area to the large water storage area, and the first water pumping device sequentially has a first state of pumping water from the small water storage area and a second state of incapable of pumping water from the small water storage area.

In other words, when the first water pumping device and the second water pumping device are in a continuous and uninterrupted working state, the flow of the water outlet end of the second water pumping device is equal to or greater than the flow of the communication hole.

When the flow of the water outlet end of the second water pumping device is equal to the flow of the communication hole, namely the second water pumping device can keep the water level in the small water storage area unchanged, the first water pumping device independently enables the water level in the small water storage area to fall, when the water level in the small water storage area falls to the water inlet end of the first water pumping device, air enters the first water pumping device from the water inlet end, the density of the air is far lower than that of the water, namely the resistance of the first water pumping device to the transmission assembly suddenly decreases, at the moment, when a user moves the mop plate up and down with the same force, the moving speed of the mop plate is relatively increased due to the decrease of the resistance of the transmission assembly, so that the flow of the water outlet end of the second water pumping device is larger than that of the communication hole, the water level in the small water storage area further falls to be lower than the water inlet end of the first water pumping device, and the first water pumping device only has air in the first water pumping device, the water spraying part does not spray water any more.

When the flow of the water outlet end of the second water pumping device is larger than the flow of the communication hole, namely the second water pumping device can enable the water level in the small water storage area to gradually fall, and the water level in the small water storage area falls to a water inlet end lower than the first water pumping device according to the same principle, so that only air exists in the first water pumping device, and the water spraying part does not spray water any more.

Furthermore, in order to enable the flow of the water outlet end of the first water pumping device to be equal to or larger than the flow of the communication hole, the up-and-down moving speed of the mop plate has a lowest value, and through observation, the time range of pushing and pulling the mop up and down by a user is between 0.5s and 3s, so the transmission ratio of the movement of the mop and the second water pumping device is converted at the slowest speed, the flow of the water outlet end of the second water pumping device can be larger than the flow of the communication hole, and the second state that the first water pumping device can not pump water is ensured, so that the flat mop can be squeezed to be dry.

The first water pumping device and the second water pumping device can be piston pumps, diaphragm pumps or peristaltic pumps and the like, and the second water pumping device and the first water pumping device are of the same structure, so that the types of required parts can be reduced, and the cost and the assembly difficulty of the mold are reduced.

The flat mop is characterized in that a transmission assembly 4 is arranged on the bucket body or the cover body, the transmission assembly is in transmission connection with the first water pumping device and the second water pumping device, and when the mop plate moves up and down in the mop cleaning opening, the mop plate or the mop rod of the flat mop is in transmission connection with the transmission assembly, namely, the flat mop drives the first water pumping device and the second water pumping device to work through the transmission of the transmission assembly.

Furthermore, the transmission assemblies in the embodiment are two same groups, and each group of transmission assemblies is in transmission connection with one water pumping device respectively. In other embodiments, the transmission assembly may have only one group, and two water pumping devices may be connected to one group of transmission assemblies at the same time.

Specifically, as shown in fig. 6, a bracket 20 is provided at the lower end of the cover, and the first water pumping device 5a, the second water pumping device 5b and the transmission assembly 4 are mounted on the bracket.

A first water outlet channel 201 is formed by the support and the cover body, and the water outlet channel is communicated with the water outlet end of the first water pumping device and the water spraying port 202.
