Roller brush with extrusion and uniform liquid discharging structure

Abstract

The invention discloses a roller brush with an extrusion and uniform liquid discharging structure. The roller brush comprises a roller capable of being connected onto a bracket, wherein the roller comprises a hollow roller body and a sponge layer covering the roller body; and the sponge layer is in sleeving joint with the roller body. The following technical measures are adopted: at least four rows of liquid discharging holes, which are formed in an equal radian, are formed in the periphery of the roller body; the liquid discharging holes are connected with a unidirectional liquid discharging structure in a matched manner; the unidirectional liquid discharging structure comprises a pulling piece with an opening and closing structure; one side of the pulling piece is connected with the roller body; and the other side of the pulling piece is in clearance fit with the roller body. By virtue of the roller brush, coating contained in the roller brush does not leak randomly when the roller brush is used for brushing a wall body; and the coating only can leak out at the position on which the roller is close to the wall body, and the coating does not leak out when the roller brush is pulled downwards.

Description

technical field [0001] The invention relates to a wall brush, in particular to a roller brush with a structure for extruding and uniform liquid discharge. Background technique [0002] When decorating a house, painting the walls is indispensable, but when painting the walls, we often encounter such a problem. While painting the paint on the wall, the paint on the paint brush will drip continuously and dirty the ground Therefore, before painting the walls, a layer of newspaper or plastic paper should be laid on the ground, which will increase the amount of renovation work. And when painting the ceiling of the top, the paint on the paint brush may even drip onto the clothes and body of the painter and cause a lot of trouble for cleaning. In addition, whether the current paint brush is a brush type or a roller type, its ability to hold paint is very limited. After a few times of painting, the paint must be re-dipped to paint again. Now there are many roller brushes with built-...

[0002] When decorating a house, painting the walls is indispensable, but when painting the walls, we often encounter such a problem. While painting the paint on the wall, the paint on the paint brush will drip continuously and dirty the ground Therefore, a layer of newspaper or plastic paper should be laid on the ground before painting the walls, which will increase the amount of renovation work

And when painting the ceiling at the top, the paint on the paint brush may even drip onto the clothes and body of the painter and cause a lot of trouble for cleaning.

In addition, whether the current paint brush is a brush or a roller, its ability to hold paint is very limited. After a few times of painting, the paint must be re-dipped to paint again. Now there are many roller brushes with built-in storage bins. The paint is poured and seeps out of the cylinder through the small holes distributed on the roller, but this roller brush still cannot prevent the paint from leaking from the small holes due to gravity, and the paint can only seep out from the holes below due to gravity. Did not effectively solve the problem of leakage
