Description

Technical Field

[0001] The utility model relates to the field of cleaning devices, in particular to a dust removal and cleaning device for painting exterior walls of buildings. Background Art

[0002] Exterior wall painting refers to the use of cleaning or smearing tools made of bundles of wool palm, etc., to paint walls with chalk, coatings (latex paint, oil paint), etc., smearing mud, lime, cement and other materials on the surface of the building, and sometimes brushing on mortar or making various patterns. The main construction process is to manually clean the exterior wall base first, and then the workers fill the putty with a brush head, and then scrape the putty on the part, and smooth it to complete the exterior wall painting.

[0003] Before painting the wall cloth, workers are often required to use a specific brush to clean the dust on the wall end, and then use scrapers and other tools to level the wall surface to prevent small raised spots or dust on the wall end from affecting the adhesion of the paint. Due to the high height of the exterior wall, workers need to use extended tools to clean it, which will increase the workers' workload and affect the cleaning effect of the wall. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a dust removal and cleaning device for painting the exterior walls of buildings to solve the technical problems mentioned in the above background technology.
