Description

Roller assembly, cleaning device and cleaning system Technical Field The disclosure relates to the technical field of cleaning tools, and in particular relates to a roller assembly, cleaning equipment and a cleaning system. Background The cleaning robot is a floor cleaning device integrating various cleaning functions. The chassis of the cleaning robot is generally equipped with a walking assembly and a cleaning assembly, and when the walking assembly walks on the supporting surface, the cleaning assembly can perform cleaning treatment on the surface, including but not limited to mopping, dust collection and the like. During operation of the cleaning robot, for some surfaces that do not require cleaning, the cleaning robot may lift the cleaning assembly to maintain a distance from the surface. However, the cleaning assembly still has the potential to drop water or other debris onto the surfaces, causing them to become accidentally contaminated. In addition, even when cleaning a surface to be cleaned, if excessive water drops, the drying time of the surface increases, and the cleaning efficiency decreases. Disclosure of utility model In view of the above problems in the prior art, the present disclosure provides a roller assembly, a cleaning apparatus, and a cleaning system to improve the technical problems of accidental contamination of non-cleaning surfaces and excessive dripping of water from cleaning surfaces. To achieve the above and other related objects, a first aspect of the present disclosure provides a drum assembly mounted on a cleaning apparatus for performing a cleaning operation on a surface to be cleaned. The roller assembly comprises a roller support and a roller, wherein the roller support comprises a containing cavity, a clear water inlet and a dirt sucking port, the clear water inlet and the dirt sucking port are communicated with the containing cavity, an opening is formed in the bottom of the containing cavity, the roller is rotatably installed in the containing cavity, a part of the roller is exposed from the opening, a gap is formed between the top of the roller and the top wall of the containing cavity, the clear water inlet and the dirt sucking port are communicated with the gap, the roller and the inner wall of the containing cavity are contacted with each other to form a contact part, and the contact part is located between the gap and the opening along the rotating direction of the roller. In the technical scheme, a gap is formed between the top of the roller and the top wall of the accommodating cavity, and the clean water inlet is communicated with the gap. The self-cleaning water inlet can spray clean water onto the roller for cleaning the roller, and meanwhile, excessive clean water which is not absorbed by the roller can be generated, and the gap can contain the excessive clean water. The contact part formed by the mutual contact of the roller and the inner wall of the accommodating cavity is arranged between the gap and the opening, and can prevent excessive moisture from dripping from the opening along with the rotation of the roller. Meanwhile, the drum is further favorable for sucking away the water on the inner wall of the accommodating cavity, and the excessive water is prevented from dripping along the inner wall of the accommodating cavity. In addition, the dirt sucking port is also communicated with the gap, and excessive water can be sucked out through the dirt sucking port. By the arrangement, the technical problems of unexpected pollution of the non-cleaning surface and excessive water dripping on the cleaning surface can be improved. In one embodiment of the roller assembly, the roller bracket comprises a cover plate covered on the outer side of the roller, and the roller assembly further comprises a first scraping strip assembly, wherein the first scraping strip assembly is connected to one end of the cover plate far away from the clean water inlet, and at least part of the first scraping strip assembly is in contact with the roller to form at least part of the contact part. In the above technical scheme, the contact part formed between the cover plate and the roller at the contact part of the first scraping strip component and the roller extends to further prevent excessive water from dripping, and the roller is also favorable for taking away the water on the inner wall of the contact of the first scraping strip component and the roller, so that the water is prevented from dripping along the inner wall of the first scraping strip component. The first scraping strip component can further enable the water and the cleaning agent on the surface of the roller to be distributed more uniformly, local over-wet or over-dry is avoided, and the cleaning effect is ensured to be consistent. In an embodiment of the roller assembly of the disclosure, the first scraper assembly includes a first hard portion and a first soft portion, one end of the first hard portion is connect
