Background
With the development of modern technology, cleaning tools are diversified, including brooms, mops, floor wipers, dust collectors, and the like. The vacuum cleaner is an unconventional cleaning tool, but the noise of the vacuum cleaner is very loud and uncomfortable. And the garbage is cleaned only by sucking the garbage into the garbage box.
Brooms, mops and floor wipers are cleaning tools of the mop type, which generally have a fixed cleaning part, the cleaning capacity of which is determined by the dirt removing and absorbing capacity of the cleaning part. Since the cleaning portion is contaminated as soon as it comes into contact with the soiled floor, the cleaning power is gradually reduced during the subsequent cleaning process, and complete cleaning cannot be achieved, particularly when a large area is continuously swept. Therefore, the cleaning articles must be washed frequently, which is very troublesome.
For Chinese consumers, sweeping and mopping are necessary when cleaning the floor, and the floor cannot be thoroughly cleaned only by sweeping or mopping. However, these existing mopping and sweeping all-in-one machines either need to be washed continuously, or have complex structures and high manufacturing cost, so that ordinary consumers are prohibited.
Moreover, existing cleaning tools can only clean dry waste (brooms, cleaners, etc.) or liquid waste (mops, etc.). It is said to be unwarranted by the hand in terms of cleaning either particularly poor or laborious (e.g., multiple washes with rags) of dry and wet mixed waste, particularly sticky waste (e.g., syrup, ketchup, etc.).
In addition, the mopping machine or the mopping and sweeping all-in-one machine can be provided with a water tank for storing water. The existing water tanks are generally of a simple box-like structure and are fixedly mounted on the machine, and water squeezed out of the drum may overflow to the ground and be inconvenient to clean.

Fig. 6-12 illustrate a cleaning tool according to a preferred embodiment of the present disclosure.
The cleaning tool of the present disclosure includes a cleaning module and a water circulation module. Wherein the cleaning module comprises a roller 111. The drum 111 has at least two layers, and the outermost layer is a sponge layer for absorbing water and cleaning garbage. The innermost layer is a supporting layer and is made of hard materials. The driving motor can be sleeved in the roller 111, so that the space can be saved, and the size of the cleaning tool can be reduced.
The water circulation module includes a water tank 260 and a sump assembly 270. The specific structure of the water tank 260 and the water tank assembly 270 is shown in fig. 1-5, and will not be described herein. The water blocking rib 271A, the water pressing lever 272 and the drum 111 together form a second water tank a2 (water containing space). The first water tank a1 and the second water tank a2 are connected through the second contaminated water inlet 271 b. The water pressing bar 272 is parallel to the drum 111 and interferes with the sponge layer of the drum 111. The water tank 260 is connected to a first water tank a 1.

The roller 111 is detachably mounted to the housing by a roller quick release button 536a and a roller quick release catch 536 b. The second roller brush 131 is detachably mounted on the housing via a roller brush quick release button 537a and a roller brush quick release buckle 537 b. The flume assembly 270 is removably mounted to the housing by a flume roll brush quick disconnect 538.
As shown in fig. 8, a shovel bar is further provided in the cleaning module, and one end of the shovel bar is in contact with the ground and has an arc-shaped working surface (point a to point b). A garbage passage is formed between the arc-shaped working surface and the outer circumferential surface of the drum 111. The second rolling brush 131 is located between the drum 111 and the garbage box 141 for cleaning the dry garbage on the surface of the drum 111.
The roller 111 has a snap at one end to facilitate removal from the housing 500. The motor is installed inside the drum 111, and the rotation shaft is installed on the housing. The driving motor drives the hard material inside the roller transmission mechanism to rotate around the axis of the hard material, so that the sponge layer is driven to rotate, and the surface of the sponge layer moves circumferentially.
When the roller 111 rolls on the ground, the sponge layer 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 111. When the rotary drum rotates to the position of the shovel bars a, the particles of the dry garbage leave the ground and are extruded by the shovel bars to continue rotating together with the rotary drum 111. When the shovel strip is rotated, the sponge layer is restored to deform due to the loss of the compression of the shovel strip when the shovel strip is rotated to the position b, and the dry garbage particles wrapped by the sponge layer are released and some of the dry garbage particles cannot be released and are brushed down by the bristles of the second rolling brush 131. The bristles of the second rolling brush 131 are in contact with the sponge layer, and the second rolling brush 131 moves in the opposite direction to the roller 111. The released or brushed-down garbage enters the garbage box 141 along the moving track of the second drum brush 131.

The user promotes the burnisher back-and-forth movement, and before contacting ground, the sponge layer on cylinder 111 is slightly wet (absorb water and be unsaturated), and after contacting ground, the slightly wet sponge layer absorbs subaerial liquid rubbish on one side, cleans subaerial solid rubbish on the other side.
With the cooperation of the shoveling bars 112, the large solid garbage carried up by the rollers 111 passes through the gap between the shoveling bars 112 to the point b, and then enters the garbage box 141 along the moving track of the second rolling brush 131. The small-particle garbage is embedded into the sponge layer, reaches the position b along with the movement of the roller 111, is brushed by the bristles of the second rolling brush 131, and enters the garbage box 141 along the movement track of the second rolling brush 131.
The roller 111 continues to roll to the press bar 272. The water pressing rod 272 presses the sponge layer to press out the sewage in the sponge layer. The water pressing rod 272 always interferes with the sponge layer of the roller 111, the sponge layer is always extruded, and in the using process, the water pressing rod 272 is used for continuously wringing the roller 111 and then spraying clean water. That is, the drum 111 is always cleaned during use. The squeezed sewage flows into the first water tank a1 through the second water tank a2, then enters the water tank 260 through the sewage pipe, is filtered by the filter element 263, enters the transit water tank 233, and then is sprayed onto the drum 111 through the purified water pipe under the action of the water pump to clean the drum 111. The above steps are continuously circulated, and the ground is cleaned.
Meanwhile, the ozone generator 222a continuously sprays ozone into the transfer water tank 233, thereby simultaneously sterilizing and disinfecting the water in the water tank a and the ground.
