A kind of cavity type paint roller brush

Abstract

The invention discloses an intracavity coating roller brush. The roller brush comprises a brush roll. The outer side wall of the brush roll is provided with a plurality of flash holes communicated with an external brush layer. The brush roll is internally provided with a coating barrel used to store coating. The right side of the coating barrel is provided with a feeding device. The feeding deviceis opened driven by an opening and closing device. The opening and closing device is arranged on the left side wall of the brush roll in a passing-through manner. The surface of the coating barrel isprovided with a plurality of material leaking holes. The coating barrel is communicated with the internal of the brush roll through the material leaking holes. Through arranging the coating barrel which can overflow coating in the brush roll, the brush roll does not need to supplement coating through a method of dipping the coating. The coating stored in the coating barrel can greatly reduce thenumber of repeated dipping, so as to improve painting efficiency. The overflow brush layer soaking method from inside out can greatly reduce conditions that the coating is dripped in a painting process, and conditions that the coating is dripped and wasted in a painting process are reduced.

Description

technical field [0001] The invention relates to a paint painting tool, in particular to an inner-cavity paint roller brush. Background technique [0002] In the process of decoration, it is often necessary to paint the wall surface. During the painting process, the wall is brushed by using a roller brush to pick up the paint. The brush layer on the roller brush can be dipped from the outside. Pick up the paint, but the amount of paint that the brush absorbs is limited each time. If too much paint is dipped in the process of dipping the paint, the paint will accumulate on the surface of the roller brush, and the paint will easily drip from the brush during the brushing process. Therefore, when painting a wall, it is often necessary to repeatedly dip the paint from the paint bucket, but the paint is prone to dripping during the dipping process, and this method of repeatedly dipping the paint is very labor-intensive And the crushing efficiency increases the labor cost of crush...

[0002] In the process of decoration, it is often necessary to paint the wall surface. During the painting process, the wall is brushed by using a roller brush to pick up the paint. The brush layer on the roller brush can be dipped from the outside. Pick up the paint, but the amount of paint that the brush absorbs is limited each time. If too much paint is dipped in the process of dipping the paint, the paint will accumulate on the surface of the roller brush, and the paint will easily drip from the brush during the brushing process. Therefore, when painting a wall, it is often necessary to repeatedly dip the paint from the paint bucket, but the paint is prone to dripping during the dipping process, and this method of repeatedly dipping the paint is very labor-intensive and crushing efficiency, which increases the labor cost of crushing, and the dripping paint is easy to pollute the environment, causing waste and increasing the consumption of paint
