Description

Technical Field

[0001] This invention relates to the field of wall cleaning technology, and in particular to a wall cleaning device for building walls. Background Technology

[0002] Interior decoration, especially home decoration, is a popular concept for improving quality of life and can be seen as a major indicator of increased happiness. Originating in China in the late 1980s, decoration, also known as interior design or renovation, refers to a complete set of construction and design plans implemented within a specific area and scope, including plumbing and electrical work, walls, floors, and landscaping, based on certain design concepts and aesthetic rules. Because wall surfaces may develop peeling paint after becoming damp, affecting the quality of the renovation, it is usually necessary to remove the paint. Current methods involve manual or machine removal. Manual removal is not only inefficient but also labor-intensive, while existing machines often struggle to effectively remove paint from the corners between walls and ceilings.

[0003] Wall plaster removal involves cleaning up plaster that has developed cracks. As society develops and people's living standards improve, they pay more attention to the quality of their living environment. When renovating a new house, it's necessary to remove the existing plaster before leveling and other work. Traditional plaster removal is mainly done manually using scrapers and other tools, which is very laborious and requires the use of scaffolding or other auxiliary tools for working at height, making it very troublesome and inefficient. Furthermore, the process generates a lot of dust, polluting the work environment and threatening the health of the workers. In addition, plaster will fall directly to the ground during the process, requiring separate cleaning, which also generates a lot of dust, polluting the work environment and making the process extremely tedious.

[0004] Application number CN202010509097.4 discloses an environmentally friendly wall cleaning device for building decoration, including a frame structure, a support structure disposed within the frame structure, and a cleaning structure disposed outside the frame structure. The frame structure includes a rotating frame, a drive frame disposed within the rotating frame, a connecting pipe disposed between the rotating frame and the drive frame, an inflatable frame disposed at one axial end of the drive frame, an exhaust pipe disposed on the inflatable frame, and a first fan disposed on the exhaust pipe. The rotating frame is provided with air blowing holes. This invention, by configuring a drive frame, a rotating frame, and a connecting pipe between the drive frame and the rotating frame, enables the drive frame to not only drive the rotating frame to rotate but also to spray air towards the wall surface through the rotating frame, thereby blowing away impurities and other debris, facilitating wall cleaning, improving cleaning efficiency, and reducing manual labor intensity.
