[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0023] like Figure 1-3 As shown, the utility model proposes an exhibition hall wall treatment device, comprising a protective cover 1, one side of the protective cover 1 is fixedly connected to an exhaust cover 2, and the exhaust cover 2 is fixedly connected to a handle pipe 3;

[0024] A driving motor 4 is fixedly mounted on the exhaust hood 2, and the driving motor 4 is connected to a grinding disc 6 via a rotating extraction mechanism 5;

[0025] An auxiliary blocking mechanism 7 is provided at the opening of the protective cover 1 .

[0026] In an optional embodiment, the rotary extraction mechanism 5 includes a rotating box 51 and bristles 52. The rotating box 51 is fixedly connected to the driving shaft of the driving motor 4 through a connecting rod 53. A partition plate 54 is fixedly installed inside the rotating box 51 for dividing the interior of the rotating box 51 to form an air inlet duct. The air inlet duct forms an air inlet at the periphery of the rotating box 51. A partition plate 54 extends out of the air inlet at each air inlet. The bristles 52 are fixedly installed on the partition plate 54 outside the rotating box 51, and an opening is formed in the middle of one side of the rotating box 51 close to the connecting rod 53.

[0027] The fan blades 55 are fixedly mounted on the connecting rod 53 .

[0028] It should be noted that the bristles 52 clean the wall surface and prevent dust from escaping during grinding; the partition plate 54 extends out of the rotating box 51 and plays a role in digging wind guides to guide the dust to the inside of the rotating box 51.

[0029] In an optional embodiment, the auxiliary blocking mechanism 7 includes an annular shell 71, an elastic member 72 and a ball 73. An annular groove for inserting the annular shell 71 is opened in the annular wall of the protective cover 1. One end of the elastic member 72 is fixedly connected to the inner wall of the annular groove, and the other end of the elastic member 72 is fixedly connected to the annular shell 71. The ball 73 is rotatably sleeved on the side of the annular shell 71 away from the elastic member 72.

[0030] Specifically, the elastic member 72 is a spring or a spring sheet.

[0031] It should be noted that, under the action of the ball 73, the annular shell 71 can move along the wall; under the action of the elastic member 72, the annular shell 71 can enter the protective cover 1 and then adapt to the protrusion of the wall.

[0032] In an optional embodiment, the handle tube 3 is connected to a discharge tube, and the discharge end of the discharge tube extends below the liquid surface.

[0033] It should be noted that the discharge pipe can be extended into the water bucket, and water is added into the water bucket to submerge the discharge end of the discharge pipe, thereby achieving the effect of washing air.

[0034] In the utility model, the handle tube 3 is held and the grinding disc 6 is brought into contact with the wall. At this time, the ball 73 is in contact with the wall, and the annular shell 71 plays a role of auxiliary blocking of the dust generated by the grinding disc 6. The drive motor 4 is started, and the drive motor 4 drives the rotating box 51, the fan blades 55 and the grinding disc 6 to rotate. The rotation of the fan blades 55 plays a role of suction. The rotating box 51 drives the partition plate 54 to rotate, which plays a role of guiding the generated dust into the interior of the rotating box 51, and the fan blades 55 extract the middle part of the rotating box 51 to discharge the extracted dust into the interior of the handle tube 3, thereby reducing the phenomenon of dust dispersion harming the human body.
