[0030] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0031] The applicant believes that existing sanding devices for building decorative panels, such as handheld sanders, often generate a large amount of flying dust and ash during use. This not only easily pollutes the surrounding environment and objects, making subsequent cleaning difficult, but also makes it easy for people in the vicinity to inhale the dust, causing physical harm. Therefore, these devices have certain shortcomings and potential hazards.

[0032] Example 1:

[0033] Therefore, the applicant proposes a polishing device for architectural decoration, such as Figures 1-3 As shown, it includes a grinding mechanism and a dustproof mechanism 3 installed on the grinding mechanism to block grinding dust.

[0034] The grinding mechanism includes a housing assembly 1, a drive assembly, and a sanding disc assembly 2. The drive assembly is installed inside the housing assembly 1. The sanding disc assembly 2 is connected to the drive end of the drive assembly. Sanding paper is provided on the side of the sanding disc assembly 2 away from the drive assembly. The drive assembly is used to drive the sanding disc assembly 2 and the sanding paper to rotate at high speed, thereby grinding the surface of the board.

[0035] In this application, the grinding mechanism mainly includes a housing assembly 1, a drive assembly, and a sanding disc assembly 2, etc. The relevant structure can be referred to in the prior art such as angle grinders. The principle is mostly to use a motor or other drive assembly to drive the spindle to rotate. The spindle and the sanding disc assembly 2 are connected by a screw thread and locked with a pin. When the spindle rotates, it can drive the sanding disc assembly 2 to rotate at high speed. Depending on the grinding material and requirements, the sanding disc assembly 2 can be used to grind with a grinding wheel or a wheel with sandpaper installed. It can grind and polish metal plates, wood panels, walls, etc. The housing assembly 1 is provided with a handheld part, which can facilitate hand operation by the user and has the advantages of convenient use and high efficiency.

[0036] However, traditional sanding disc components 2 often generate a large amount of flying dust and debris when sanding materials, which can easily pollute the environment and objects, and be inhaled by personnel, causing damage to their health. Therefore, a dust prevention mechanism 3 is set up, as follows.

[0037] like Figures 1-3 As shown, the dustproof mechanism 3 includes an upper dustproof cover 301, a lower dustproof cover 302, an outer connector 303, a connector cap 304, and a movable component 4.

[0038] The upper dust cover 301 is installed at a predetermined position on the housing assembly 1, the lower dust cover 302 is movably disposed on the side of the upper dust cover 301 near the sand disc assembly 2, the external connector 303 is installed at a predetermined position on the upper dust cover 301, the connector cap 304 is snapped onto the external connector 303 to seal the end of the external connector 303, the external connector 303 is connected to the flying debris blocking cavity and is used to connect an external suction device to absorb flying debris.

[0039] In this application, a pair of upper dust covers 301 are provided. The pair of upper dust covers 301 are correspondingly fastened to the outside of the housing assembly 1 by matching bolts. The lower dust cover 302 is U-shaped on the side near the sanding disc assembly 2 to collect some of the flying dust that is blocked from falling. The lower dust cover 302 and the upper dust cover 301 are arranged around the outside of the sanding disc assembly 2 and form a flying dust blocking cavity on the outside of the sanding disc assembly 2 to block the sanding flying dust. In the initial state, the lower surface of the lower dust cover 302 is not lower than the sanding surface of the sandpaper.

[0040] During installation, sealing strips or similar materials can be used between a pair of upper dust covers 301 to improve the sealing of the connection between the pair of upper dust covers 301.

[0041] like Figure 2 As shown, the movable component 4 is installed between the upper dust cover 301 and the lower dust cover 302, and is used for the lower dust cover 302 to move outside the sand disc assembly 2. The movable component 4 includes a mounting bracket 401, a movable column 402, a limit nut 403 and a movable spring 404.

[0042] The mounting bracket 401 is connected to the lower dust cover 302. Several movable columns 402 are provided, and the movable columns 402 are installed at predetermined positions on the mounting bracket 401. The movable columns 402 pass through the upper dust cover 301 and are slidably connected to the upper dust cover 301. The movable spring 404 is provided between the upper dust cover 301 and the mounting bracket 401 and is located outside the movable column 402. The end of the movable column 402 is provided with a limiting thread of predetermined length. The limiting nut 403 is adapted to the limiting thread and is used to limit the movement range of the movable column 402.

[0043] In this embodiment, the upper dust cover 301 has a sliding hole adapted to the movable column 402. The mounting bracket 401, the movable column 402, and the limiting nut 403 allow the lower dust cover 302 to be movably connected to the upper dust cover 301. The limiting nut 403 can limit the movement range of the lower dust cover 302 by working with the upper surface of the mounting bracket 401. At the same time, the outer wall of the lower dust cover 302 slides in contact with the inner wall of the upper dust cover 301, which can improve the relative sealing of the dust blocking cavity. The inner diameter of the bottom of the lower dust cover 302 is larger than the outer diameter of the sand disc assembly 2, so as not to affect the normal operation of the sand disc assembly 2.

[0044] During installation, the internal components of the dustproof mechanism 3 are sequentially installed on the housing assembly 1. First, a pair of upper dustproof covers 301 are snapped into predetermined positions on the housing assembly 1. Then, the pair of upper dustproof covers 301 are tightened using matching bolts. Next, the movable spring 404 is sleeved on the outside of the movable column 402, and the lower dustproof cover 302 is snapped into the upper dustproof cover 301, so that several movable columns 402 pass through the sliding holes on the upper dustproof cover 301. Finally, the limit nut 403 is tightened on the end of the movable column 402.

[0045] In use, the user holds the housing assembly 1 and places the sanding disc assembly 2 parallel to the surface of the material to be sanded. At this time, the lower surface of the lower dust cover 302 will abut against the surface of the material to be sanded. Since the lower surface of the lower dust cover 302 protrudes from the sanding surface of the sanding disc assembly 2 in the initial state, the lower dust cover 302 will drive the movable column 402 to move on the upper dust cover 301, and drive the movable spring 404 to deform. The movable spring 404 will then drive the lower surface of the lower dust cover 302 to press against the surface of the material. Then, the drive mechanism is activated to drive the sanding disc assembly 2 to rotate, which can sand the surface of the material. During the process, the lower dust cover 302 and the upper dust cover 301 can block the dust in the sanding range, reducing the occurrence of a large amount of dust flying, thereby protecting the surrounding environment, objects and personnel.

[0046] Meanwhile, the smooth and horizontal lower surface of the lower dust cover 302 allows it to continuously contact the surface of the board, thereby enabling the sanding disc assembly 2 to grind parallel to the surface of the board. This reduces the occurrence of uneven grinding surfaces caused by the sanding disc assembly 2 tilting, thus improving grinding efficiency.

[0047] Example 2:

[0048] Further research by the applicant revealed that the mounting bracket 401, movable column 402, limit nut 403 and movable spring 404 provided in Embodiment 1 of this application have problems such as inconvenience in installation during actual use, and the lower dust cover 302 may get stuck on the surface of the plate when it moves against the plate. Therefore, another movable component 4 and driven component 5 are provided.

[0049] like Figures 4-6 As shown, the movable component 4 includes a connecting plate 405, a movable plate 406, a connecting lug 407, and a connecting screw 408; the driven component 5 includes a mounting plate 501 and a driven ball bearing 502.

[0050] The connecting plate 405 is disposed between the upper dust cover 301 and the lower dust cover 302. The movable plate 406 is connected between the connecting plate 405 and the lower dust cover 302. The connecting ear 407 is correspondingly connected to the connecting plate 405 and the upper dust cover 301. The connecting screw 408 is threaded onto the connecting ear 407 and is used to connect the upper dust cover 301 and the connecting plate 405. The mounting plate 501 is connected to the outside of the lower dust cover 302. The driven ball 502 is mounted on the mounting plate 501 and is used to move in conjunction with the lower dust cover 302.

[0051] In this embodiment, the connection plate 405, movable plate 406, connecting ear 407, and connecting screw 408 facilitate the assembly and disassembly of the upper dust cover 301 and the lower dust cover 302, and also improve the sealing performance after the upper dust cover 301 and the lower dust cover 302 are connected. The elasticity of the movable plate 406 replaces the movable column 402, the limiting nut 403, and the movable spring 404 in the embodiment, which also simplifies the structure and makes it easier to assemble and disassemble and saves on usage costs.

[0052] Meanwhile, during use, the user holds the housing assembly 1 and moves the sanding disc assembly 2 continuously on the plate, thereby polishing the surface of the plate in all directions. The mounting plate 501 and driven ball bearing 502 are designed to facilitate the movement of the lower dust cover 302, reducing the chance of the lower dust cover 302 getting stuck on the plate, thus ensuring normal movement and polishing. The mounting plate 501 and driven ball bearing 502 can also be replaced with universal wheels or other moving components.

[0053] It should be noted that, in motion, the lower tangent of the driven ball 502 is on the same horizontal plane as the lower surface of the lower dust cover 302, which allows the lower dust cover 302 to continuously contact the surface of the board, thereby reducing the chance of dust leaking out from the lower surface of the lower dust cover 302.

[0054] In addition, in this application, components such as the upper dust cover 301 and the lower dust cover 302 can be made of transparent materials, which makes it easier for users to observe the sanding process of the sanding disc assembly 2 on the plate.

[0055] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes in form and detail may be made to the present invention without departing from the spirit and scope of the appended claims.
