Description

Technical Field

[0001] This utility model belongs to the field of decoration and renovation engineering, specifically a wall sanding device for decoration and renovation. Background Technology

[0002] Decoration and renovation projects improve the durability and lifespan of buildings by enhancing their heat insulation, sound insulation, and moisture-proofing functions. They also protect various building components from natural wind, rain, and moisture erosion, creating a better production, living, and working environment for people. Painting and wallpapering are mainly used for wall decoration. Before decorating the walls, a layer of putty needs to be applied. The main function of putty is to level the surface. To achieve a smoother, finer, and more uniform wall surface, sanding is required. This requires wall sanding equipment specifically designed for decoration and renovation projects. Although traditional sanding equipment has dust collection bags, extremely fine dust (especially gypsum and putty powder) can still penetrate the equipment through motor cooling holes and structural gaps. Long-term accumulation can lead to accelerated wear of motor bearings, abnormal noises, or even jamming, and a sharp reduction in the lifespan of precision mechanisms such as gearboxes. Therefore, we have designed a new wall sanding device for decoration and renovation. Utility Model Content

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] A decorative wall sanding device, such as Figure 1 , 2 As shown, the device includes a protective cover 1 with an opening on one side. A motor 2 is fixedly mounted inside the protective cover 1. A grinding disc 3 is fixedly connected to the output shaft of the motor 2. The rotating shaft of the grinding disc 3 is coaxially fixedly connected to the output shaft of the motor 2 and rotatably mounted within the protective cover 1 via a bearing seat. A handle 4 is fixedly connected to the other side of the protective cover 1. A fixing block 5 is fixedly mounted on the top of the handle 4 and is fixedly mounted on the protective cover 1. A miniature air pump 6 is fixedly mounted at the end of the handle 4. An airflow channel 7 is opened in the handle 4. A conical cavity 8 is opened on the fixing block 5. Evenly distributed circumferential ventilation holes 9 are opened around the motor 2 on the protective cover 1. The air outlet of the miniature air pump 6 is connected to the airflow channel 7, the cavity 8, and the ventilation holes 9. The air inlet of the miniature air pump 6 is connected to the outside. This utility model has a simple structure and ingenious design. It only adds a miniature air pump 6 and an airflow channel to the existing handle 4. The outflowing air can be designed to pass through the heat dissipation fins of the motor 2, which not only provides dust protection but also assists in heat dissipation, achieving two goals at once, meeting market demand, and is suitable for promotion. When using this invention, first start the micro air pump 6 and motor 2, hold the handle 4 and align the grinding disc 3 with the wall for grinding. Since the end of the handle 4 is far from the grinding area, the air is relatively clean. The micro air pump 6 draws in clean air and passes it through the airflow channel 7, cavity 8, and ventilation hole 9 in sequence, and finally blows it over the outer periphery of the motor 2. The clean air is continuously sent into the protective cover 1, forming a positive pressure environment that is slightly higher than the external air pressure. When there is a gap between the grinding disc 3 and the protective cover 1, the internal air will flow out, thereby effectively preventing external dust from being drawn into the protective cover 1. The outflowing air can also pass through the heat dissipation fins of the motor 2, which not only prevents dust but also assists in heat dissipation, achieving two goals at once.

[0017] Specifically, as shown in the figure, the protective cover 1 in this embodiment has several air ducts 20 on its side wall that are connected to the corresponding ventilation holes 9. The ends of the air ducts 20 are inclined and aligned with the gap between the grinding disc 3 and the protective cover 1. Airflow can enter the air ducts 20 through the ventilation holes 9 in sequence, preventing powder from entering the interior of the protective cover 1 from the gap between the grinding disc 3 and the protective cover 1.

[0018] Specifically, as shown in the figure, the handle 4 in this embodiment has an air vent 30, which is connected to the air inlet of the micro air pump 6. A filter screen 31 is fixedly installed on the air vent 30. The filter screen 31 can further prevent dust from entering.

[0019] Furthermore, as shown in the figure, the handle 4 in this embodiment has a cyclone separation chamber 40 at its end. The micro air pump 6 is located above the cyclone separation chamber 40. The cyclone separation chamber 40 is connected to the air inlet and air outlet 30 of the micro air pump 6. A dust collection cup 41 is detachably installed below the cyclone separation chamber 40. Air enters tangentially, generating a vortex. Centrifugal force is used to directly separate most of the visible coarse dust particles and throw them into the dust collection cup 41 below, ensuring that the air entering the micro air pump 6 is relatively clean.

[0020] Furthermore, as shown in the figure, the cyclone separator 40 in this embodiment is provided with a conical platform 50 below it, and a threaded hole 51 is provided on the handle 4. The outer periphery of the dust collection cup 41 is provided with an external thread that mates with the threaded hole 51. The conical platform 50 facilitates the concentrated downward sliding of separated dust, and the collected dust can be quickly disassembled and cleaned by rotating the dust collection cup 41.

[0021] Furthermore, as shown in the figure, a brush 60 is fixedly provided on the outer periphery of one side of the opening of the protective cover 1 in this embodiment. The brush 60 can provide cushioning and protection for the wall.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
