Description

Technical Field

[0001] This utility model belongs to the field of brush technology, and more specifically, relates to a roller brush. Background Technology

[0002] A paint roller is a tool used to apply paint or coatings. It is mostly made of engineering plastics and fibers, but some are made of natural wool. Roller brushes are used in daily construction projects and interior decoration when large areas of paint are needed. Roller brushes are usually equipped with handles for the convenience of workers.

[0003] Small-area repairs typically don't require roller brushes, meaning existing roller brushes can only repair large areas. Small areas require other tools for repair, making them relatively limited in function. Also, since roller brushes can only pick up a limited amount of paint, workers need to constantly dip the roller brush into the paint bucket. However, constantly swinging the entire roller brush is physically demanding for workers, and painting walls is also quite troublesome. Utility Model Content
