TECHNICAL FIELD
[0001] The utility model relates to the field of building decoration especially relates to a dustproof structure of wall surface polisher. BACKGROUND
[0002] In the field of building decoration, wall surface polishing is a crucial and frequent process, which aims to make the wall surface smooth and provide a good foundation for subsequent decoration work such as paint brushing and wallpaper laying. The traditional wall surface polishing method relies on manual sanding, which is not only labor-intensive and inefficient, but also difficult to ensure uniformity. With the advancement of technology, a dustproof structure for wall surface polishers has emerged to address the drawbacks of manual polishing.
[0003] The polisher is equipped with a simple dust cover, but lacks flexibility in design. When polishing the wall surface, the flatness of the wall surface is often not the same, and there are various protrusions, depressions, and complex parts of inside and outside corners. The rigid dust cover cannot adaptively adjust according to the undulations of the wall surface, resulting in gaps between the dust cover and the wall surface when polishing these special parts, allowing dust to escape and reducing the dust collection efficiency. In addition, rigid contact can easily scratch the wall surface, especially on some fragile decorative wall surfaces, leaving scratches and damaging the aesthetic appearance of the wall surface, making subsequent repair work tedious and complex.
[0004] During long-term polishing operations, the bottom of the dust cover of the polisher with a dust cover rubs against the wall surface frequently, which quickly causes wear and tear. This not only shortens the service life of the dust cover and increases equipment maintenance costs, but also makes the bottom of the worn dust cover less compatible with the wall surface, further exacerbating dust leakage.
[0005] Therefore, it is necessary to provide a dustproof structure for a wall surface polisher to solve the above technical problems. SUMMARY
