[0002] Modern building decoration, especially residential decoration, often requires paint, and the application of paint requires special tools. With the development of science and technology, the application tools of paint have become diversified, and various advanced paint application tools are dazzling. Despite this, the paint roller brush, as the most common paint application tool, still has its own unique features. The roller of the current roller brush does not store materials. When brushing the wall, the paint is adsorbed on the rough surface of the roller surface by manually dipping the paint, and then the rough surface is contacted with the wall and other objects that need to be painted, and the paint is rolled onto the surface of the object. This operation method requires repeatedly dipping the paint onto the rough surface, which is not only laborious, but also has low efficiency of the paint rolling brush, and the paint is easy to drip during the dipping process, dirtying the ground. At the same time, manual dipping of the paint is likely to cause uneven distribution of the paint on the rough surface, resulting in uneven coating of the paint roller brush, affecting the effect of the paint rolling brush.
