Description

technical field [0001] The invention relates to the field of paint application, in particular to a paint application device with paint dripping prevention function. Background technique [0002] Paint is a chemical mixture coating that can firmly cover the surface of objects for protection, decoration, signs and other special purposes. The authoritative book "Coating Technology" in China's coating industry defines it as follows: coating is a material that can be coated on the surface of objects by different construction techniques to form a solid, continuous solid with firm adhesion and certain strength. film. The film thus formed is generally called a coating film, also known as a paint film or a coating. [0003] However, when the existing technology is actually used, the traditional paint application is to use a roller brush to frequently dip the paint, and then use the roller brush to smear the wall. During the process of dipping, the paint will drip to the ground, cau...

Problems solved by technology

[0003] However, when the existing technology is actually used, the traditional paint application is to frequently dip the paint with a roller brush, and then apply the roller brush to the wall. During the dipping process, the paint will drop to the ground, causing certain damage to the environment. At the same time, the traditional roller brush is cylindrical and cannot be applied when facing the corner of the wall, requiring the user to apply the wall twice, thus increasing the construction time
