[0006] Most of the above-mentioned existing documents improve the structure of the wall painting device. However, during the operation of the existing wall painting device for interior decoration of buildings, the user is required to repeatedly contact the paint in the paint bucket to replenish the paint. The steps of cumbersome up and down movement are relatively cumbersome, which brings great inconvenience to the user's operation and has certain usage limitations. Summary of the invention

[0007] The object of the present invention is to provide a wall painting device for interior decoration of buildings, so as to solve the problem proposed in the above-mentioned background technology that during the work process, the user needs to repeatedly contact the paint in the paint bucket to replenish the paint, and the steps of cumbersome up and down movement are relatively cumbersome, which brings great inconvenience to the user's operation and has certain usage limitations.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a wall painting device for indoor decoration of a building, comprising a preset docking frame, a built-in nesting piece and a docking roller brush piece, wherein the upper end of the preset docking frame is docked with the built-in nesting piece, and a docking roller brush piece is arranged on the outer side of the built-in nesting piece, and the wall is painted by the docking roller brush piece;

[0009] An external docking tube is provided through the inner side of the built-in nesting part, and an auxiliary supply part is connected to the upper end of the external docking tube. A preset liquid storage cavity is provided between the built-in nesting part and the docking roller brush part. A guide hole is provided on the inner wall of the docking roller brush part, and a built-in annular groove is provided on the inner surface of the docking roller brush part, and the built-in annular groove and the guide hole are connected to each other. A self-supply structure is provided on the inner side of the built-in nesting part, and the supply device of the brush liquid inside the built-in nesting part is self-controlled by the self-supply structure.

[0010] The interior of the docking roller brush member is provided with a self-moving structure, and the brushing liquid stored in the preset liquid storage cavity is evenly released through the self-moving structure.

[0011] Furthermore, the self-supply structure is provided with a resistance docking piece, and the resistance docking piece is nested and docked in the inner wall of the built-in nesting piece, the inner wall of the external docking tube is fixedly connected with a first return spring, and the outer side of the first return spring is docked with a sealing fitting, and the sealing fitting is arranged on the inner side of the external docking tube.

[0012] Furthermore, a guide docking hole is provided on the inner wall of the external docking tube, and the guide docking hole corresponds to the upper end position of the abutting docking piece;

[0013] The inner wall of the butt-jointed rolling brush member is fixedly connected with a fixed top block, and the fixed top block corresponds to the lower end position of the butt-jointed member.

[0014] Furthermore, the overall hardness of the docking roller brush component gradually increases from the outside to the inside, and during the process of the docking roller brush component rotating along the outer side of the built-in nested component, the fixed top block at its inner end will contact the abutting docking component, exerting pressure on it to push the abutting docking component to move along the guide docking hole toward the inner wall of the external docking tube. The fixed top block is a trapezoidal structure, and the fixed top block and the inner wall of the docking roller brush component are an integrated structure.

[0015] Furthermore, the abutting docking parts are symmetrically distributed about the center point of the docking roller brush part, and the abutting docking parts are forced to move upward to apply pressure to the contacting sealing fitting parts. The sealing fitting parts form an elastic structure along the inner wall of the external docking tube through the first return spring. The sealing fitting parts in the upward state make the guide docking holes on the surface of the external docking tube in a connected state.

[0016] Further, the self-movable structure is provided with a first preset annular airbag, and the first preset annular airbag is arranged on the inner wall of the docking roller brush member, a second preset annular airbag is nested inside the docking roller brush member, and an air supply hose runs through the outer side of the second preset annular airbag, and the air supply hose is connected to the first preset annular airbag;

[0018] Furthermore, the second preset annular airbag is located at the outer side of the docking roller brush member, and the second preset annular airbag is connected to the first preset annular airbag through an air supply hose.

[0019] Furthermore, when the outer side of the docking roller brush is pressurized, the second preset annular airbag on the inner wall is pressurized in advance, and when the second preset annular airbag supplies air to the inside of the first preset annular airbag to expand, it pushes the outer nested connector to move outward.

[0020] Furthermore, the thrust of the nested connector when it moves outwards, combined with the repulsive force between the magnets of the same name, pushes the arc-shaped fitting parts to move inward along the preset liquid storage cavity, and supplies the stored paint liquid inside the preset liquid storage cavity to the built-in annular groove through the guide hole.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The wall painting device for indoor decoration of buildings is provided with a self-supply structure. When the user paints the wall by rotating the docking roller brush piece along the outer side of the built-in nesting piece, the fixed top block at the inner end thereof will contact the abutting docking piece, and apply pressure to the abutting docking piece to push the abutting docking piece to move along the guide docking hole toward the inner wall of the external docking tube. After the abutting docking piece is forced to move upward, it will apply pressure to the contacting sealing fitting piece, so that the sealing fitting piece forms an elastic structure along the inner wall of the external docking tube through the first return spring. The upwardly moved sealing fitting piece makes the guide docking hole on the surface of the external docking tube in a connected state, and then the paint liquid is self-supplying to the inside of the docking roller brush piece adaptively. The user does not need to repeatedly contact the paint in the paint bucket to replenish the paint, and the cumbersome steps of up and down lateral movement are reduced, which brings convenience to the user's operation and improves the practicality of the device.

[0024] Furthermore, a self-moving structure is provided. When the second preset annular airbag located at the outer side of the docking roller brush is in contact with the wall paint and is under pressure, it will pre-supply air to the first preset annular airbag through the air supply hose to expand it, so that it pushes the nested connecting parts on the outside to move outward. The thrust when the nested connecting parts move outward combined with the repulsive force between the magnet parts of the same name will push the arc-shaped fitting docking parts in the preset liquid storage cavity to move inward, and the stored paint liquid inside the preset liquid storage cavity will be supplied to the built-in annular groove through the guide hole, so that the stored paint liquid will be evenly transmitted to the inner wall of the docking roller brush close to the outside, so as to carry out the subsequent painting process more evenly.
