It is an ideal building energy-saving and environmentally friendly material, so it is widely used in new and old building insulation projects. When spraying polyurethane coating on the corresponding area of ​​the wall, the polyurethane material tends to spread and spray to the surrounding area, affecting the subsequent construction of other areas. In addition, since polyurethane material is easy to color, it will affect the overall appearance of the wall after spraying.

[0003] In the prior art, a utility model patent with publication number CN219901450U provides a wall cleaning machine. This wall cleaning machine can quickly clean polyurethane materials, has high working efficiency, and has low grinding disc loss. The above-mentioned wall cleaning machine includes: a shell, a cleaning mechanism and a hand-held mechanism; the cleaning mechanism is arranged on the shell, and the cleaning mechanism includes a scraping member and at least one grinding member, and the scraping end of the scraping member and the grinding end of the grinding member are located on the same side; the hand-held mechanism is connected to the shell.

[0004] The handheld mechanism of the wall cleaning machine cannot adjust the angle, resulting in a small adjustable range of the distance between the operator and the wall, which easily affects the normal wall cleaning work. The dust collection mechanism cleans the dust, and the electrical appliance needs to be manually operated and needs to be cleaned frequently, which increases the workload of the operator. For this reason, we propose a building interior wall cleaning machine to solve the above problems. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. Hold the operating lever and pull the bottom end of the strap. The strap pulls the support rod to rotate on the operating lever. The rotation of the support rod causes the second torsion spring to be subjected to force. The rotation of the support rod causes the shell to rotate accordingly. The rotation of the shell causes the grinding mechanism to swing accordingly. After the grinding mechanism contacts the wall, the shell is restricted from rotating as a whole. The operating lever continues to rotate, pushing the shell to rotate on the support rod, so that the grinding mechanism fits and contacts the wall. Then stop pulling the strap and restrict the strap to the strap buckle at the same time. Then move the operating lever from top to bottom, so that the grinding mechanism grinds from top to bottom to clean the wall. The adjustable range of the distance between the operator and the wall is larger, while avoiding affecting the normal wall cleaning work.

[0015] 2. When the grinding mechanism fits the wall, the free end of the rubber strip contacts the wall and is squeezed and bent until the grinding mechanism fits the wall. The torsion spring pushes the support block to flip outward, so that the free end of the rubber strip stably fits the wall. The dust generated by the grinding mechanism falls onto the rubber strip, slides to the support block through the rubber strip, slides on the support block into the shell, and falls into the collection seat, making it easy to receive the dust cleaned by the grinding mechanism, reducing the use of electrical appliances and thus reducing the workload of operators.

[0022] Hold the operating rod 52 and then pull the bottom end of the strap 55. The strap 55 pulls the support rod 51 to rotate on the operating rod 52. The rotation of the support rod 51 causes the torsion spring 2 53 to be stressed. The rotation of the support rod 51 causes the shell 1 to rotate accordingly. The rotation of the shell 1 causes the grinding mechanism 3 to swing accordingly. After the grinding mechanism 3 contacts the wall, the shell 1 is restricted from rotating as a whole. The operating rod 51 continues to rotate, pushing the shell 1 to rotate on the support rod 51, so that the grinding mechanism 3 fits and contacts the wall. Then stop pulling the strap 55 and at the same time restrict the strap 55 to the strap buckle 54. Then move the operating rod 52 from top to bottom, so that the grinding mechanism 3 grinds from top to bottom to clean the wall. The adjustable range of the distance between the operator and the wall is larger, while avoiding affecting the normal wall cleaning work.

[0023] A material receiving device 4 is provided on the shell 1 below the grinding mechanism 3, and the material receiving device 4 is used to receive the dust generated by cleaning the grinding mechanism 3. The material receiving device 4 includes a roller 41 rotatably connected to the opening of the shell 1, and the free end of the roller 41 passes through a torsion spring 42 and is connected to a support block 43. The outer end of the support block 43 is connected to a rubber strip 44 for supporting the free end of the rubber strip 44 to contact the wall. The roller 41 is fixedly connected to the support block 43 for supporting the rotation of the support block 43. One end of the torsion spring 42 is connected to the shell 1, and the other end is connected to the support block 43 for pushing the support block 43 to flip outward. A collecting seat is provided in the shell 1 on the side of the support block 43 away from the rubber strip 44. The rubber strip 44 is an elastic rubber strip. The top surfaces of the rubber strip 44 and the support block 43 are provided with a smooth coating. The rubber strip 44 is arc-shaped and the opening faces upward.

[0024] When the grinding mechanism 3 is in contact with the wall, the free end of the rubber strip 44 contacts the wall and is squeezed and bent until the grinding mechanism 3 is in contact with the wall. The torsion spring 42 pushes the support block 43 to flip outward, so that the free end of the rubber strip 44 is stably in contact with the wall. The dust generated by the grinding mechanism 3 falls onto the rubber strip 44, slides to the support block 43 through the rubber strip 44, slides on the support block 43 into the shell 1, and falls into the collection seat, so that it is easy to receive the dust cleaned by the grinding mechanism 3, reduce the use of electrical appliances, and thus reduce the work intensity of the operator.

[0025] Working principle: In the utility model, the operating rod 52 is held, and then the bottom end of the strap 55 is pulled. The strap 55 pulls the support rod 51 to rotate on the operating rod 52. The rotation of the support rod 51 causes the torsion spring 53 to be stressed. The rotation of the support rod 51 causes the housing 1 to rotate accordingly. The rotation of the housing 1 causes the grinding mechanism 3 to swing accordingly. After the grinding mechanism 3 contacts the wall, the housing 1 is restricted from rotating as a whole. The operating rod 51 continues to rotate, pushing the housing 1 to rotate on the support rod 51, so that the grinding mechanism 3 is in close contact with the wall. Then, the pulling of the strap 55 is stopped, and at the same time, the strap 55 is restricted on the strap buckle 54. Then, the operating rod 52 is moved from top to bottom, so that the grinding mechanism 3 grinds the wall from top to bottom. The surface can be cleaned, and the adjustable range of the distance between the operator and the wall is larger, while avoiding affecting the normal wall cleaning work. When the grinding mechanism 3 fits the wall, the free end of the rubber strip 44 contacts the wall and is squeezed and bent until the grinding mechanism 3 fits the wall, and the torsion spring 42 pushes the support block 43 to flip outward, so that the free end of the rubber strip 44 stably fits the wall. The dust generated by the grinding mechanism 3 falls onto the rubber strip 44, slides to the support block 43 through the rubber strip 44, slides on the support block 43 into the shell 1, and falls into the collection seat, so that it is easy to receive the dust cleaned by the grinding mechanism 3, reduce the use of electrical appliances, and thus reduce the work intensity of the operator.

[0026] The grinding mechanism 3 is prior art and will not be described in detail here.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
