The roller 132 includes an inner layer of hard glue and a sponge layer wrapped around the outer layer of hard glue. The end of the hard glue may be fixed to the cleaner head body 131 by a connector 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.

The trash can 135 is located between the drum 132 and the clean water tank 133. Optionally, a waste bin 135 is removably mounted on the cleaning head body 131. The shoveling bars 136 have arc-shaped working surfaces which form a trash passage between the arc-shaped working surfaces and the outer circumferential surface of the drum 132, through which the trash enters the trash can 135. Alternatively, the wiper strip 137 may include a friction portion and a drainage portion (not shown in the drawings), wherein the friction portion and the drainage portion respectively interfere with (i.e., press against) the drum 132. The friction part can scrape off the garbage adhered on the roller, and the scraped garbage enters the garbage bin 135 through self weight. The drain prevents water squeezed by the water pressing bar 138 from flowing along the drum 132 to the ground. The drain forms a sump a together with the drum 132, the water pressure lever 138, and the cleaning head body 131. The cleaning head body 131 is provided with a tank inlet connected to the clean water tank 133 and a tank outlet (not shown) connected to the foul water tank body 122. Clean water in the clean water tank 133 is introduced into the tank a through the tank inlet for washing the drum 132, and the sewage squeezed by the water pressure lever 138 is introduced into the filtering apparatus 134 through the tank outlet, and the filtered sewage is introduced into the sewage tank body 122.

In this embodiment, the filter device 134 is a filter cartridge, as shown in fig. 2, and is located at one side of the clean water tank 133. In this embodiment, the sewage flowing out of the outlet of the water tank can flow into the filter cartridge 134 by its own weight. In order to clean the sewage passage more conveniently, in this embodiment, the sealing cover 131a of the sewage passage is detachable. Optionally, the filter cartridge 134 is removably mounted on the cleaning head body 131.

The fresh water in the fresh water tank 133 is used to wash the drum 132. A water pump may be used to pump fresh water from the fresh water tank 133 into the basin a. The clean water tank 133 is fixed to the cleaner head body 131, so that a water check structure can be prevented from being designed, and the complexity of the structure and the risk of water leakage from the water tank to the interface can be reduced. Optionally, the clean water tank 133 is integrally formed with the cleaning head body 131. In this embodiment, the cleaning tank 133 is provided with a clean water tank cover 133a, and clean water is filled into the clean water tank 133 by opening the cover.

The sump assembly 120 includes a sump body 121 and a sump housing 122. The waste tank body 122 is used for containing waste water. Alternatively, the sewage tank body 122 may be detachably mounted to the sewage tank body 121 to facilitate pouring of the sewage.

In this embodiment, an arc-shaped movable guard plate 131b is disposed at the front end of the cleaner head body. However, when the roller 132 needs to be taken out, the shield 131b is rotated clockwise to take out the roller 132. After the roller 132 is mounted, the cover 131b is rotated counterclockwise and closed. At this time, the protector 131b may moisturize the drum 132, and prolong a moisturizing time of the drum 132. Meanwhile, the guard plate 131b may also have a certain anti-collision function, so as to protect the roller 132.

As shown in fig. 11 and 12, the waste water tank body 122 is provided with a cover 122a, a sealing ring 122b, a latch 122c, a button 122d, a handle 122e, a pumping port 122f and a pumping port 122 g. In this embodiment, the cover 122a is opened to discharge the sewage from the sewage tank body 122. Sewage enters the sewage tank body 122 from the pumping port 122 f. A sewage pipe (not shown) therein is directly connected to the filter cassette 134, and filtered sewage is pumped from the filter cassette 134 to the sewage tank body 122 through the sewage pipe by an air pump.

When the cleaning equipment of the embodiment is used for cleaning dry garbage on the ground, when the roller 132 rolls on the ground, the sponge layer of the roller 132 is pressed and deformed by the particles of the dry garbage on the ground, and the particles of the dry garbage are wrapped by the sponge layer through deformation, so that the particles of the dry garbage are separated from the ground and rotate together with the roller 132. When turned to the position of the shoveling bars 136, the particles of dry waste leave the ground, are squeezed by the shoveling bars 136, and continue to rotate with the drum 132. When turning over shovel strip 136, when changeing the dustbin 135 entrance, owing to lose the oppression of shovel strip 136, the recovery of sponge layer warp, releases its dry rubbish granule of parcel, and rubbish gets into in the dustbin 135 under the effect of dead weight and elasticity.

Some dry garbage having small particles may not be ejected into the garbage can 135 by the elastic deformation amount of the sponge layer, and it may be scraped off by the friction portion of the scraping bar 137 to fall into the garbage can 135. If not removed from drum 132, it will turn to sink a as drum 132 rotates. The water flows in the tank a to create a scouring force and also to remove the trash from the surface of the drum 132. In addition, the water pressing bar 138 also interferes with the drum 132, where the garbage can be scraped. The waste removed from the tank a and the pump wand 138 flows with the water stream into the filter cartridge 134. The sewage is filtered and pumped to the sump housing 122, leaving the waste in the filter box 134 for disposal. Through the arrangement, the dry garbage can be completely and cleanly removed from the ground, and the device cannot be blocked.

When wet garbage is cleaned using the cleaning apparatus of the present embodiment, the sponge layer of the drum 132 absorbs the wet garbage. The wet trash travels with the drum 132 to the tank a where the water flows and the pressing bar 138 presses the sponge layer of the drum 132, and the wet trash is released from the sponge layer, enters the filter cartridge 134 with the water flow, and is then sucked to the sump housing 122.

When the cleaning apparatus of the present embodiment is used to clean the viscous garbage, the viscous garbage adheres to the sponge layer of the drum 132 and partially permeates into the sponge layer of the drum 132. The drum 132 is rotated further, the friction part of the scraping bar 137 can hang down the viscous garbage adhered on the surface of the drum 132, and the scraped garbage enters the garbage bin 135 by self weight. The viscous waste that cannot be scraped off reaches the sink a. The water flows in the water tank a to wash the viscous garbage adhered to the surface of the drum 132. And the pressing bar 138 can also scrape off the sticky trash adhered to the surface of the drum 132. Under the combined action of the water flow and the water pressing rod 138, the viscous garbage penetrating into the sponge layer is released, and the viscous garbage adhered to the sponge layer is also removed and enters the filter cartridge 134 along with the water flow. A portion of the garbage can be caught by the filter cassette 134 and the filtered sewage is sucked to the sewage tank body 122.
