Title:
CLEANING DEVICE AND ANTI-WINDING STRUCTURE THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/142086
Kind Code:
A1
Abstract:
A cleaning device and an anti-winding structure. The anti-winding structure comprises a cleaning base (2) and a cleaning rolling brush (3); the cleaning base (2) is provided with a water spraying surface (24); the cleaning rolling brush (3) is mounted at the front end of the water spraying surface (24); water spraying holes (243) spraying water towards the cleaning rolling brush (3) are formed in the upper portion of the water spraying surface (24); a water suction port (246) is formed in the lower portion of the water spraying surface (24); tooth-shaped scraping strips (245) and water scraping strips (244) are further provided at the position, between the water spraying holes (243) and the water suction port (246), of the water spraying surface (24); the tooth-shaped scraping strips (245) are used for preventing fibers from being wound on the cleaning rolling brush (3); the water scraping strips (244) are used for scraping water on the cleaning rolling brush (3); and the cleaning rolling brush (3) sequentially passes by the water suction port (246), the tooth-shaped scraping strips (245), the water scraping strips (244), and the water spraying holes (243) when rotating. The anti-winding structure can prevent the problem that dirty water absorbed in the cleaning rolling brush (3) cannot be scraped off due to deformation of the cleaning rolling brush (3) caused by winding of fibers on the cleaning rolling brush (3).
