Electric roller brush

Abstract

The invention discloses an electric roller brush, which is a coating tool mainly for roll coating on a wall surface and mainly comprises a motor, a main machine pump, a feeding pipe, a storage battery, a roller brush and other structures. The electric roller brush is arranged on a material barrel with a barrel lid; the lower end of the feeding pipe passes through the main machine pump and extends into the material barrel to be in contact with coating; the upper end of the feeding pipe is connected with the roller brush; and the coating at the lower end of the feeding pipe is continuously delivered to the roller brush at the upper end of the feeding pipe by using the motor to start the main machine pump to work. The technical scheme disclosed by the invention comprises the point that a switch device with a more novel structure is arranged on the roller brush and is synchronously started by rotating a manually-driven roller, thereby realizing the quantitative feeding of the roller brush and avoiding the defects of serious leakage, the pollution to peripheral environment and the damage to human body of the traditional structure due to a lagged feeding mode. The improved structure has the advantages of small volume, simple and convenient filler, high quantity, simple maintenance, light roll coating, convenience, high working efficiency, wide application range and the like.

Description

technical field [0001] The invention relates to a rolling brush structure for rolling coating walls, in particular to an electric rolling brush. Background technique [0002] The roller brush is a practical painting tool. There are three main structures of the roller brush commonly used in the market: the first is the ordinary roller brush, which needs to be used to stick the paint while rolling the wall. This structure has low working efficiency. The dripping of the paint is serious, especially when the ceiling is painted, and the dripping of the paint will also cause damage to the human skin, and pollute the clothes and the floor; High-pressure spraying, the high-speed mist paint sprayed by the roller brush is easy to pollute other indoor decorations, and what is more serious is that this mist paint is inhaled by people, causing harm to people's physical and mental health; the third structure Similar to the "portable electric roller brush machine" with the published Chine...

[0002] The roller brush is a practical painting tool. There are three main structures of the roller brush commonly used in the market: the first is the ordinary roller brush, which needs to be used to stick the paint while rolling the wall. This structure has low working efficiency. The dripping of the paint is serious, especially when the ceiling is painted, and the dripping of the paint will also cause damage to the human skin, and pollute the clothes and the floor; High-pressure spraying, the high-speed mist paint sprayed by the roller brush is easy to pollute other indoor decorations, and what is more serious is that this mist paint is inhaled by people, causing harm to people's physical and mental health; the third structure Similar to the "portable electric roller brush machine" with the published Chinese patent No. 00219874.6, it is mainly composed of a material barrel, a motor, a main engine pump, a feeding pipe, a roller brush, etc. A manual switch is installed on the barrel. Although this tool overcomes the disadvantages of the first two tools, there are still many defects in the actual use process. First, this rolling brush is a hand-held manual control switch to control the feeding method , since the manual switch is located on the bucket full of paint, during the rolling process of the roller brush, one hand needs to hold the brush to roll the paint, and the other hand must always hold the bucket full of paint and hold the switch , once the roller stops brushing, the control switch must be turned off, otherwise there will be too much paint injected into the roller, causing the paint to flow out of the roller and pollute the environment, so the application limitations of the portable electric roller brush are also reflected. If it is too large, the material tank is too large, and if too much material is added at one time, human physical energy will be wasted on the link of material lifting, thereby reducing work efficiency, but if the material tank is too small, the frequency of feeding will increase, which will also reduce efficiency; at the same time , the electric roller brush also has the defects that the storage tank is not easy to fill with raw materials, the structure of the pump body is relatively complicated, and it is not easy to maintain and clean
