Description

Technical Field

[0001] The utility model relates to the technical field of roller brush equipment, in particular to an electric roller brush. Background Art

[0002] In the process of paint coating, a roller brush is usually needed. The paint is dipped by the rotatable brush roller at the end of the roller brush, and then it is pushed against the surface of the attachment through a bracket, so that the brush roller rolls on the surface of the attachment, thereby coating the dipped paint on the surface of the attachment.

[0003] However, in actual use, current roller brushes are roughly divided into two groups, manual and electric. The manual type has a simple structure and low cost, but is more laborious, while the electric type is more expensive, but also more efficient and comfortable. However, current electric roller brushes are mostly directly driven by a motor when in use, and cannot achieve rapid and accurate deceleration and stop at the end of the roller brushing, which can easily cause damage to the position that has been roller brushed, requiring secondary repairs, which is very inconvenient. For this reason, a special electric roller brush is provided to solve the above problem. Utility Model Content
