Description

Electric roller brush

Technical Field

The invention relates to the technical field of roller brushes, in particular to an electric roller brush.

Background

The roller brush is also called a roller, is divided into three types, namely long hair, medium hair and short hair, and is a tool for rolling and coating large-area paint. The rolling surface is wide in range, so that the brush is the most labor-saving and time-saving brush, and particularly, after the extension rod is connected, the high part of the wall surface or the ceiling can be easily painted, but the defect is that paint splashing is easily caused. The roller brush is mainly used for rolling and coating large-area paint in architectural decoration engineering and can be used for rolling and coating various mixed paints. When the paint is required to be evenly painted, the roller is preferably placed into a paint bucket to be fully absorbed, then the roller is taken out and rolled on the inclined plane for a few times, and the redundant paint is extruded to paint the wall.

The existing people can use various mixed paints when decorating houses and manufacturing furniture, the traditional various mixed paint brushing methods only adopt a roller brush, the roller brush is used only by brushing straightly, if the paint is even, a roller in the roller brush is placed into a paint bucket and is fully absorbed, then the roller is taken out to roll on an inclined plane for several times, and redundant paint is extruded and then the wall painting or the furniture painting is started. Because the structural advantage of cylinder brush, often need paint at the eminence for a long time, if the coating that has brushed the cylinder brush at every turn takes off again and is stained with various ready mixed paint, inefficiency like this wastes physical power and time, often various ready mixed paint on the cylinder brush are stained with too much material and can drop subaerially simultaneously, the polluted environment.
