In this embodiment, the water tank 112 and the body 111 are integrally formed. In other embodiments of the invention, the water tank may also be removably mounted to the body. The integrated forming can avoid designing a water check structure and reduce the complexity of the structure and the risk of water leakage of the water tank butt joint.

The roller 113 includes an inner layer of hard glue and a sponge layer wrapped around the hard glue. The end of the hard rubber can be fixed on the body 111 through a connecting piece such as a bearing. The roller driving mechanism drives the hard rubber to rotate around the axis of the hard rubber through the roller transmission mechanism to drive the roller to rotate, so that the surface of the roller does circular motion. An arc-shaped movable guard plate may be provided on the body 111 to facilitate the removal of the drum 113.

The wiper strip assembly 213, the water pressing strip 115, the drum 113 and the water tank cover 116 form a water tank a. The wiper strip assembly 213 is mounted on the body 111 to interfere with (i.e., press) the drum 113 to prevent the water in the water tank a from flowing along the drum 113 to the ground. The water pressing bar 115 also interferes with the drum 113 to press out water in the drum 113 to clean the drum 113 and maintain the humidity of the drum 113 at a proper level. The wiper strip assembly 213 includes a wiper fixing portion 213c, and a wiper strip 213a and a water bar 213b covering the surface of the fixing portion 213c, the wiper strip 213a and the water bar 213b may be rubber strips, the wiper strip 213a and the water bar 213b are made of soft materials, and the fixing portion 213c and the water bar 115 are made of hard materials.

The water pressing strip 115 comprises a straight line section and arc sections arranged at two ends of the straight line section. During the operation of the cleaning tool, the roller 113 is continuously rotated, and the water pressing bar 115 extrudes the sewage in the roller. The straight section and the arc sections at the two ends can keep continuous extrusion on the roller. The arrangement can lead the sewage squeezed out from the two ends of the roller to be gathered and drained into the water tank.

The wiper strip 213a has a Y-shape. The "Y" shaped tip portion interferes with the roller of the roller cleaning tool and helps to peel off debris adhering to the roller during operation of the cleaning tool.

The water bar 213b is shaped like a "Y". The water retaining part 213b-1 and the water receiving bar 213b-2 are Y-shaped and bifurcate respectively. The water stop portion 213b-1 interferes with the drum 113 and cooperates with an arc-shaped working bar (not shown) of the water pressing bar 115 to press out water in the drum 113 during the operation of the cleaning tool. As the drum 113 rotates, water extruded from the drum 113 flows to a water storage space formed by the water pressing bar 115, the water blocking bar 213b and the drum 113. Both ends of the water bar 213b are formed in an arc shape. Through the cooperation of the water bar 213b and the arc 213b-3, the sewage extruded from the drum 113 is gathered and guided to the water tank. This arrangement keeps the portion of the drum 113 pressed by the arc 213b-3 unsaturated (i.e., not fully filled with water) to prevent the water in the water tank from flowing out of both ends of the drum 113.

In this embodiment, as shown in fig. 5, the cover 116 is reversible, and can be turned over along the shaft 116a to facilitate cleaning of the waste in the tank a.

That is, the water in the water tank 112 can be recycled. The period of water change can be set according to actual conditions, and the purpose of saving water can be achieved. Alternatively, the washing tub a may be provided as an inclined waterway so that the water in the tub a may flow into the water tank 112 from the tub outlet by its own weight.

The impeller assembly 117 is positioned in a direction of the inlet of the tub to throw the water in the water tank 112 into the tub inlet, thereby allowing the water in the water tank 112 to enter the tub a to wash the drum 113. The impeller assembly 117 comprises an impeller 117a and a reduction gearbox 117b, the impeller 117a is installed in the impeller cavity, the reduction gearbox 117b is installed in the body 111, the impeller 117a rotates rapidly, and water in the water tank 112 is thrown into the inlet of the water tank under the action of centrifugal force.

In order to prevent the impeller from being stuck by garbage, a filtering device can be arranged in the water tank 112, and water in the water tank enters the impeller assembly after being filtered by the filtering device, so that the function of protecting the impeller assembly can be achieved. In this embodiment, the filter device is a filter 118, but in other embodiments of the present invention, other types of filter devices are also possible.
