Description

Technical Field

[0001] This utility model relates to the field of polishing equipment technology, and more specifically, to a wall dust-reducing polishing device for interior decoration. Background Technology

[0002] During interior decoration, sanding equipment is used to smooth walls, remove impurities, improve aesthetics, and ensure the adhesion and overall effect of subsequent paint or wallpaper. To reduce dust pollution, improve the working environment for workers, and prevent health risks, sanding equipment needs a dust suppression function. In existing technology, a dust suppression hood is fitted over the outside of the sanding disc, and a dust collection mechanism is connected to the hood. To ensure sanding and dust suppression effectiveness, the bottom surface of the dust suppression hood is on the same plane as the working surface of the sanding disc. During use, both the working surface of the sanding disc and the bottom surface of the dust suppression hood are in contact with the wall. The sanding disc is then rotated to sand the wall, and the dust generated is trapped inside the dust suppression hood, which is then removed by the dust collection mechanism.

[0003] However, the existing technology mentioned above still has shortcomings. With continuous use, the working surface of the grinding disc will wear down, resulting in a positional difference between the working surface of the grinding disc and the bottom surface of the dust cover, which will not achieve a good grinding effect and the effect will not be ideal. If the grinding disc is frequently replaced, the cost of use will increase. Utility Model Content

[0024] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0025] Refer to the instruction manual appendix Figures 1 to 7 A wall dust-reducing and sanding device for interior decoration includes a gripping driver 1, a sanding disc 11 is provided on the output shaft of the gripping driver 1, a dust-reducing mechanism 3 is provided on the gripping driver 1, the dust-reducing mechanism 3 includes a dust-reducing cover 31, the sanding disc 11 is located inside the dust-reducing cover 31, the area between the dust-reducing cover 31 and the sanding disc 11 is a collection area, and a dust-collecting mechanism 2 is fixedly connected to the dust-reducing cover 31. The output shaft of the gripping driver 1 drives the sanding disc 11 to rotate, and the dust-collecting mechanism 2 extracts the dust in the collection area.

[0026] A sealing mechanism 4 is provided on the dust cover 31. The sealing mechanism 4 includes an adjusting cover 41, which is slidably disposed on the outside of the dust cover 31. The bottom surface of the adjusting cover 41 is parallel to the bottom surface of the grinding disc 11. A sealing ring 411 is fixedly provided on the bottom of the adjusting cover 41. A threaded hole is provided on the output shaft of the gripping driver 1, and a bolt is threaded into the threaded hole. The grinding disc 11 is mounted on the output shaft of the gripping driver 1 by the bolt.

[0027] It should be noted that the gripping driver 1 includes a housing, and a motor is installed inside the housing. The output shaft of the motor is the output shaft of the gripping driver 1. The grinding disc 11 is mounted on the output shaft of the motor by bolts. The housing is equipped with a switch for starting and stopping the motor. The starting and stopping of the motor is a mature existing technology and will not be described in detail here.

[0028] It should also be noted that the vacuuming mechanism 2 is equipped with an air pump. The air inlet of the air pump is used to draw in gas, and the exhaust end of the air pump is fixedly equipped with a collection box. The collection box is located inside the vacuuming mechanism 2. An exhaust hole is opened on the side of the collection box away from the exhaust end of the air pump, and a filter screen is fixedly installed in the exhaust hole.

[0029] The specific implementation scenario is as follows: During use, the operator holds the driver 1, causing the sealing ring 411 to adhere to the wall surface. Pressure is then applied towards the wall, causing the adjusting cover 41 to slide on the dust collection cover 31 under pressure. The sealing ring 411 remains in contact with the wall surface. When subjected to external force, the sealing ring 411 undergoes slight deformation, isolating the collection area from the outside and improving the sealing effect within the adjusting cover 41. Then, the working surface of the grinding disc 11 moves towards the wall. When the working surface of the grinding disc 11 contacts the wall surface, the suction pump in the vacuuming mechanism 2 is activated. The grinding disc 11 is driven to rotate by holding the output shaft of the driver 1. The rotation of the grinding disc 11 grinds the wall surface. The dust generated during grinding is sucked away by the dust suction mechanism 2. The adjusting cover 41 is slidably set on the dust cover 31. That is, the bottom surface of the sealing ring 411 can be adaptively adjusted according to the working surface position of the grinding disc 11. Even if the working surface of the grinding disc 11 is worn, it can be ensured that the bottom of the grinding disc 11 and the sealing ring 411 are in the same plane during use. This not only improves the grinding efficiency of the wall surface, but also improves the sealing effect of the adjusting cover 41. Since the grinding disc 11 is always in contact with the wall during wall sanding, some dust still remains between the grinding disc 11 and the wall after sanding is completed. With the design in this solution, after the wall sanding is completed, the dust collection mechanism 2 continues to work, causing the grinding disc 11 to stop rotating. Then, the gripping driver 1 is moved to the opposite side of the wall, while ensuring that the sealing ring 411 is always in contact with the wall. The movement of the gripping driver 1 creates a gap between the grinding disc 11 and the wall, allowing the dust collection mechanism 2 to further remove the dust from the dust cover 31 and avoid dead corners in dust extraction.

[0030] Refer to the instruction manual appendix Figures 2 to 7 During operation, the dust in the collection area is extracted by the dust extraction mechanism 2. It is necessary to open an air inlet on the dust cover 31 to allow air to flow and avoid the formation of negative pressure inside the dust cover 31, which would affect normal operation. In order to blow away more dust generated during polishing according to the movement state of the adjustment cover 41 during use, specifically, an air inlet 412 is opened on the adjustment cover 41, and an air inlet 413 is opened on the dust cover 31. The air inlet 412 and the corresponding air inlet 413 are matched.

[0031] It should be noted that the sealing ring 411 is attached to the wall surface, and then pressure is applied towards the wall surface, causing the adjusting cover 41 to slide on the dust collection cover 31. When the working surface of the grinding disc 11 contacts the wall surface, the first air inlet 412 and the second air inlet 413 are connected. At this time, when the grinding disc 11 rotates to grind the wall surface, the dust collection mechanism 2 is activated to extract the gas inside the dust collection cover 31, creating a slight negative pressure inside the dust collection cover 31. External gas enters the dust collection cover 31 through the first air inlet 412 and the second air inlet 413, forming a suction airflow, collecting the dust in the collection area. Dust enters the dust collection mechanism 2 with the airflow. Air inlets 412 are evenly distributed on the side of the adjusting cover 41, allowing the airflow within the dust collection hood 31 to evenly extract dust from the collection area. After polishing, when the hand-held driver 1 is moved away from the wall, the sealing ring 411 remains firmly against the wall. With a gap between the working surface of the polishing disc 11 and the wall, the airflow entering the dust collection hood 31 through air inlets 412 can pass through this gap, further improving the dust extraction effect. Air inlets 412 are not located at the bottom of the adjusting cover 41, preventing dust from leaking out under gravity.

[0032] Refer to the instruction manual appendix Figures 1 to 4 To improve the dust extraction efficiency of the dust collection mechanism 2, a guide pipe 32 is fixedly installed on the dust cover 31, and a guide hole 311 is opened on the dust cover 31, which is located inside the guide pipe 32. A guide box 33 is fixedly connected to the guide pipe 32, and a collection pipe 21 is fixedly connected to the guide box 33. The end of the collection pipe 21 away from the guide box 33 is fixedly connected to the dust collection mechanism 2.

[0033] It should be noted that when using the device, the driver 1 is held by hand. When the sealing ring 411 is attached to the wall, the flow guide box 33 is positioned below the dust cover 31, that is, the flow guide box 33 and the collection tube 21 are arranged vertically. After the vacuuming mechanism 2 is started, the vacuuming mechanism 2 extracts the dust in the collection area. The dust generated when the polishing disc 11 polishes the wall is drawn into the flow guide tube 32 through the flow guide hole 311 under the action of airflow. Under the action of gravity, the dust will accumulate in the flow guide box 33 and wait to be drawn away by the collection tube 21, which further improves the cleaning efficiency of the dust in the collection area of ​​the dust cover 31.

[0034] Refer to the instruction manual appendix Figures 5 to 7 In order to ensure that the sealing ring 411 can always fit against the wall during use, specifically, the dust cover 31 is provided with a sliding hole 414, the adjusting cover 41 is fixedly provided with a connecting seat, the connecting seat is located in the sliding hole 414, and the same elastic element 42 is fixedly provided between the dust cover 31 and the connecting seat.

[0035] It should be noted that the elastic element 42 is set as a spring, which is fixedly mounted on the connecting seat, and the top of the spring is fixedly mounted to the inner wall of the dust cover 31.

[0036] It should also be noted that the cooperation between the sliding hole 414 and the connecting seat can guide the sliding of the adjustment cover 41. When the hand-held driver 1 applies pressure to the wall, the sealing ring 411 contacts the wall. Under the action of pressure, the adjustment cover 41 moves toward the hand-held driver 1. At this time, the elastic element 42 is compressed. When the pressure toward the wall is slowly released, the elastic element 42 is reset under the action of elasticity. By setting the elastic element 42, the sealing ring 411 can always be kept in contact with the wall according to the switching of the usage state.

[0037] Refer to the instruction manual appendix Figure 3 After use, in order to improve the efficiency of dust extraction from the dust cover 31, the bottom of the grinding disc 11 is provided with multiple auxiliary holes 111, which are equally spaced.

[0038] It should be noted that when the dust collection mechanism 2 is in the activated state, the sealing ring 411 is in contact with the wall, and there is a gap between the grinding disc 11 and the wall. The auxiliary hole 111 can help improve the efficiency of air circulation, so that the dust between the working surface of the grinding disc 11 and the wall is removed more quickly. At the same time, the auxiliary hole 111 is opened on the grinding disc 11, which can help improve the heat dissipation efficiency of the grinding disc 11 and prevent the grinding disc 11 from working at high temperature.

[0039] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
