However, most of floor washers in the current market adopt fixed hard scraping strips or scraping plates to scrape and squeeze sewage on the rolling brush, so that the scraping plates are easy to wear, the bristle wear degree of the rolling brush is increased, the service life of the rolling brush is prolonged, and the self-cleaning capacity of cleaning parts of the floor washer is reduced.
In order to solve such problems, the chinese patent of patent publication No. CN 217137938U discloses a cleaning device in which a rolling brush is not easy to wear, an extruding scraping roller of the cleaning device is rotatably disposed in a rolling brush cavity, and the extruding scraping roller can extrude the rolling brush in the rotating process of the rolling brush, so that sewage in the rolling brush can be extruded, and in addition, as friction force between the rolling brush and the extruding scraping roller can be converted into torsion force of the extruding scraping roller to drive the extruding scraping roller to rotate, the wear rate between the rolling brush and the extruding scraping roller can be remarkably reduced, and the service lives of the rolling brush and the extruding scraping roller can be prolonged, so that the cleaning device can continuously maintain a better cleaning effect.
