  10. According to claim 3 or 4, the angle between the scraper and the surface to be cleaned when they are in close contact is 80-100 degrees.
  11. A cleaning device, comprising a floor brush as claimed in any one of claims 1-10.
  12. A cleaning system includes the cleaning device as described in claim 11 and a base or station that cooperates therewith.

Description

floor brushes, cleaning equipment and cleaning systems Cross-reference of related applications This application claims priority to Chinese patent application No. 202422634545X, filed on October 30, 2024, the entire contents of which are incorporated herein by reference. Technical Field This disclosure relates to the field of cleaning equipment technology, and more specifically, to a floor brush, cleaning equipment, and cleaning system for a cleaning device. Background Technology The field of cleaning equipment technology encompasses devices including, but not limited to, vacuum cleaners, robotic vacuum cleaners, and floor scrubbers. These devices clean floors mechanically or through a combination of mechanical and chemical methods to maintain a clean and hygienic environment. In terms of mechanical design, it involves the design and manufacture of various mechanical devices, including optimizing mechanical structures to improve their performance and lifespan. In the area of household appliances, it covers a wide range of small appliances used in daily household life, including cleaning equipment. Existing cleaning equipment, such as floor scrubbers, typically uses rotating brushes to clean floors. These brushes have squeegees to remove dirt and water. Currently, the rear squeegee on the brushes of floor scrubbers is fixed and cannot be adjusted, limiting its adaptability and cleaning effectiveness in different cleaning environments. Furthermore, existing self-cleaning functions usually only clean the brush itself, failing to effectively clean and adjust the rear squeegee (also known as the scraper). This can lead to gradual wear or damage to the rear squeegee during use, thus affecting the cleaning performance and lifespan of the floor scrubber.
