Detailed Description

In the description of the present embodiment, it should be noted that, unless explicitly stated or limited otherwise, the terms "connected" and "connected" should be interpreted broadly, and may be fixedly connected, detachably connected, or integrally connected; they may be electrically connected, directly connected, indirectly connected through intervening media, or interconnected between two members. The specific meanings of the above terms in the present embodiment can be understood by those of ordinary skill in the art according to specific situations.

Before introducing the technical solution disclosed in the present invention, it is first described the usage scenario of the present invention for understanding: in order to make indoor and outdoor wall surfaces more beautiful, the wall surfaces are usually required to be decorated. For example, painting and painting on the indoor and outdoor wall surfaces, or attaching artware such as wallpaper and wall cloth with exquisite patterns on the indoor and outdoor wall surfaces. Before the decoration construction, the wall surface to be decorated needs to be polished to be smooth and reduce the surface roughness, so that the adhesive force of decorations such as paint, wallpaper and the like is better. Devices exist in the prior art for the specific sanding of walls, but these devices do not handle the dust produced by sanding very well: for example, dust generated by grinding can be dissipated into the air, so that the air quality of the construction environment is influenced; or part of dust generated by grinding can be attached to the wall surface, and the dust on the wall surface needs to be cleaned after grinding, otherwise, the dust can also influence the adhesive force of the ornament and the construction quality.

The utility model discloses a wall grinding device is promptly in order to solve above-mentioned technical problem, promptly: in the polishing process, dust generated by polishing can be prevented from escaping into the air, and the dust attached to the wall surface can be prevented from falling off.

The technical solution adopted in the present embodiment will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1, 2 and 3, a wall surface polishing device includes a negative pressure generating device 2 and a polisher 100, the negative pressure generating device 2 is used for generating negative pressure airflow, and the polisher 100 is used for polishing the wall surface in a contact manner. The sander 100 includes a housing 110, a motor 120, and a sanding member 121, and the sanding member 121 may be a sanding tool such as a turntable or a grinding wheel to which sand paper can be applied. The motor 120 is installed on the housing 110, and the output end of the motor 120 is located in the housing 110 and connected to the polishing member 121, and when polishing, the polishing member 121 contacts the wall surface. The housing 110 has an opening 111, and a brush bar 130 is provided along the circumference of the opening 111; the negative pressure generating device 2 is connected with the casing 110 through a pipeline, and negative pressure is formed in the casing 110 to suck out dust in the casing 110. The dust generated by the grinding piece 121 during grinding the wall surface is covered in the casing 110, the brush strip 130 can prevent the dust from escaping from the gap between the casing 110 and the wall surface due to the closely arranged structure, and the negative pressure airflow generated by the negative pressure generating device 2 in the casing 110 can suck out the dust; with the movement of the sanding device, the brush strip 130 can detach the wiper attached to the wall surface and further be sucked out by the negative pressure air flow.

Considering that the brush bar 130 is a delicate consumable, the bristles of the brush bar 130 may fall off and curl after a period of use, so that the bristles of the brush bar 130 become sparse. The brush strip 130 is detachably installed at the opening 111, and the residual brush strip 130 can be conveniently detached and replaced by adopting the installation mode of the structure. In one embodiment, a detachable structure is disclosed, as shown in fig. 4 and 5, a bayonet 112 is distributed at the open 111, a catch 131 matching with the catch 131 is provided on the brush strip 130, and the brush strip 130 can be inserted into the bayonet through the matching of the catch 131 and the bayonet 112.

Further, a fan capable of generating negative pressure is arranged in the negative pressure generating device 2, the fan and the motor 120 are in linkage control, the linkage control specifically means that the fan and the motor 120 can be started and stopped simultaneously through circuit connection, and the function is easy to realize in a circuit structure. It should be noted that the claimed invention is a circuit structure for realizing linkage control between the fan and the motor 120, and not a control method of the two, including but not limited to a series-parallel circuit as is common in the prior art. Preferably, as shown in fig. 6, the housing 110 has a holding portion 140, and a switch 143 for controlling the blower and the motor 120 in a linkage manner is disposed on the holding portion 140.

Further, have a spliced eye 141 on the portion 140 that grips, spliced eye 141 can be used to install telescopic link 142, through installing telescopic link 142, can prolong grinding device construction height, when polishing the wall of higher department, need not to build the scaffold frame or with the help of the object person of construction that steps up, has convenient, safe advantage.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structural changes made by the contents of the specification and the drawings, or the direct or indirect application in other related technical fields, are included in the same way in the protection scope of the present invention.
