Description

Technical Field

[0001] This utility model relates to the field of wall sanding technology, specifically a wall sanding device with dust collection function. Background Technology

[0002] A wall sanding device is an electric or manual tool specifically designed for sanding walls. Its core function is to remove unevenness, burrs, old coatings, or excess material from the wall surface using abrasive materials such as sandpaper or grinding wheels that rotate at high speed or reciprocate, resulting in a smooth and flat surface that provides a good foundation for subsequent painting, wallpapering, and other decorative processes.

[0003] Currently, most existing wall sanding devices generate a large amount of dust during sanding operations due to the friction between the high-speed rotating sanding parts and the wall surface. This dust cannot be effectively contained within a specific area and tends to scatter irregularly in all directions from the work point. This scattering dust not only quickly contaminates the entire work space, causing thick layers of dust to adhere to walls, floors, and furniture surfaces, requiring significant manpower and time for subsequent cleaning and severely impacting work efficiency; more importantly, the airborne dust can be directly inhaled by operators, and long-term exposure can easily lead to respiratory diseases such as pneumoconiosis and bronchitis, posing a serious threat to personnel health. Furthermore, the dust can irritate the eyes and skin, causing allergies and other discomfort, failing to guarantee the occupational health and safety of workers. Therefore, we propose a wall sanding device with a dust collection function. Utility Model Content

[0017] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-7 This utility model proposes a wall polishing device with dust collection function, including a dust cover 1, a frame 3 hinged to the dust cover 1, a long rod 4 threaded to the frame 3, an external thread 41 at the top of the long rod 4, and a polishing component on the dust cover 1.

[0020] In an embodiment of this utility model, in order to achieve wall sanding, the sanding assembly specifically includes a motor 21, a shaft 211 connected to the output end of the motor 21, a protrusion 212 connected to the outer wall of the shaft 211, a sleeve 213 connected to the outer wall of the sanding wheel 23, an inner groove 214 opened in the sleeve 213, the inner groove 214 and the protrusion 212 are slidably connected, a spring 215 is provided between the inner wall of the sleeve 213 and the outer wall of the shaft 211, a dust suction hood 24 penetrates through the dust cover 1 and is connected to the dust cover 1, a dust suction pipe 25 is connected to the bottom end of the dust suction hood 24, the end of the dust suction pipe 25 away from the dust suction hood 24 is connected to the air inlet of the vacuum cleaner 26, a tray 22 is provided at the bottom of the vacuum cleaner 26, and rollers are provided at the bottom of the tray 22 to improve the convenience of the vacuum cleaner 26; Furthermore, the long rod 4 passes through the rotating sleeve 42 and is sleeved with the rotating sleeve 42. The inner wall of the rotating sleeve 42 is provided with an internal thread 421, and the outer wall of the rotating sleeve 42 is provided with an anti-slip groove 422. The long rod 4 passes through the rod body 5 and is slidably connected with the rod body 5. The rod body 5 is provided with an external thread 51. The end of the rod body 5 is provided with an elastic metal sheet 52. The outer wall of the elastic metal sheet 52 is connected with a pressing block 53. The pressing block 53 is designed as a ball to reduce the friction between the pressing block 53 and the inner wall of the rotating sleeve 42. The bottom end of the rod body 5 is provided with an anti-slip sleeve 6 to increase the friction between the rod body 5 and the palm of the hand. In this invention, during use, the long rod 4 is first connected and fixed to the frame 3 via a threaded structure. Then, the long rod 4 is pulled to adjust it to the desired length. Subsequently, the rotating sleeve 42 is continuously turned to connect it to the rod 5 via a thread. During the turning of the rotating sleeve 42, the rotating sleeve 42 will move downward along the direction of the rod 5. like Figure 5 and Figure 6 As shown, the top of the inner wall of the rotating sleeve 42 is designed as a slope. When the rotating sleeve 42 moves downward a certain distance, its slope will contact the pressing block 53 on the elastic metal sheet 52, and a pressing force will be applied to the pressing block 53. Under this force, the elastic metal sheet 52 will contract inward, and the contracted elastic metal sheet 52 will fit tightly against the outer wall of the long rod 4, thereby fixing the long rod 4 and ensuring that the long rod 4 will not shift its position during use. Next, rotate the dust cover 1 to adjust it to a suitable angle, and then align the grinding wheel 23 with the wall. Apply a pushing force to the dust cover 1 using the long rod 4 to make the dust cover 1 fit against the wall. It should be noted that the surface of the dust cover 1 that contacts the wall has an arc-shaped design and a smooth surface. This design can effectively reduce the friction between the dust cover 1 and the wall, making it easier to adjust the position. When the dust cover 1 is in contact with the wall, the grinding wheel 23 will be subjected to the reaction force of the wall and will contract inward along the direction of the shaft 211. At the same time, the spring 215 will be compressed and produce elastic deformation. Under the reaction force of the spring 215, the grinding wheel 23 will press tightly against the wall to ensure stable grinding pressure. Then the motor 21 and the vacuum cleaner 26 are started: when the motor 21 is running, the power is transmitted to the grinding wheel 23 through the shaft 211 and the sleeve 213, driving the grinding wheel 23 to rotate at high speed to achieve the grinding operation on the wall. The grinding powder will be confined inside the dust cover 1 to prevent it from spreading everywhere. At the same time, after the vacuum cleaner 26 is started, a negative pressure is formed inside the dust cover 1. The dust inside will enter the suction pipe 25 through the suction cover 24 and finally be sucked into the vacuum cleaner 26 for collection, achieving dust-free grinding.

[0021] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
