Description
Technical Field
[0001] The utility model relates to the technical field of external wall cleaning, in particular to a wall cleaning brush for external walls. Background Art
[0002] The first function of painting is to beautify the wall. Wall paint not only beautifies the wall but also protects the wall. It has good waterproof, sun-proof and scratch-resistant effects overall. Exterior wall paint is harder and more water-resistant than interior wall paint. In exterior wall paint projects, a painting device will be used to apply paint to the exterior wall. The painting device specifically includes a brush handle and a paint roller. When painting, the operator holds the brush handle and controls the paint roller to apply paint on the wall.
[0003] At present, when cleaning the exterior wall, brushes are generally used to wipe the wall surface. During the cleaning process, some debris that is difficult to brush off may be encountered, such as raised dust and sand. In this case, brushes are completely ineffective and can only be cleaned with the help of other tools. A spatula is commonly used to correct the raised position, but this method cannot ensure the overall flatness of the wall surface and affects the appearance. To this end, we provide exterior wall cleaning brushes to solve the above problems. Utility Model Content
