[0037] In this embodiment, an adjustment channel is provided inside the filtering part 4; in other embodiments, the adjustment channel can also be provided in the collection part 6. The position of the adjustment channel can be flexibly adjusted according to the structural space of the device. The filtering cavity 41 and the collection drawer 61 of the collection part 6 are respectively communicated with the adjustment channel. A blocking structure is provided in the adjustment channel to isolate or connect the filtering cavity 41 and the collection drawer 61.

[0038] In this embodiment, the blocking structure includes a second telescopic rod 81 and a blocking member 82. The blocking member 82 is movably connected to the inner wall of the adjustment channel through the second telescopic rod 81.

A switching valve with a quantity adapted to the internal installation quantity is installed in the filtering part 4 to adjust the gas flow rate of the corresponding filtering chamber 41. In this embodiment, a connecting head 8, a first switching valve 43 and a second switching valve 44 are further included. The quantities of the first switching valve 43 and the second switching valve 44 are the same as the number of the filtering chambers 41. The connecting head 8 is connected to the filtering part 4. The first end of the connecting head extends into the polishing main body 1 to form a fluid communication with the dust suction channel. The second end of the connecting head is arranged inside the filtering part 4. Each filtering chamber 41 is arranged below the second end of the connecting head. This structure can better ensure that the powder is sucked into the filtering chamber 41 in cooperation with the gravity of the powder. The valve body of each first switching valve 43 is installed at the second end of the connecting head, and the actuating end of the first switching valve 43 extends into the corresponding filtering chamber 41.

[0040] In this embodiment, the number of the dust suction channels is multiple, and each dust suction channel can be communicated with the filtering chamber 41 through the connecting head. Preferably, each dust suction channel is communicated with the first end of the connecting head. In different embodiments, the dust suction channel can be one or a combination of forms such as a suction groove, an air duct and a suction pipe, and can be prepared in various forms such as grooving, welding or mechanical connection, and can be flexibly selected based on the general technical knowledge of those skilled in the art, and the present invention does not make a limitation. The multiple dust suction channels are arranged at intervals on the outer periphery of the polishing part 2 and are circularly distributed. In this embodiment, a plurality of suction grooves 111 are formed in the polishing main body 1 and on the outer periphery of the polishing part 2, and a plurality of air ducts 112 with a quantity adapted to the same side of the plurality of suction grooves 111 are arranged inside the polishing main body 1. The air ducts 112 correspond to the suction grooves 111 one by one and are communicated with each other. Each air duct 112 is communicated with the filtering chamber 41 through the connecting head 8. The multiple dust suction channels can improve the dust suction effect, suck dust in different areas on the outer periphery of the polishing part 2, and can also reduce the hidden danger that the polishing device cannot be used due to blockage.

[0041] In this embodiment, the adjustment channel is formed by the interconnected control channel 45 and branch channels 46. The number of branch channels 46 is the same as and corresponds one-to-one with the number of filter chambers 41. A discharge channel 48 is provided below the interior of the filtering part 4. The discharge channel 48 can be formed by a discharge pipe. The discharge channel 48 communicates with the collection drawer 61. Each branch channel 46 communicates with the discharge channel 48 through an inlet channel 47, that is, the number of branch channels 46 is the same as and corresponds one-to-one with the number of inlet channels 47. The number of blocking structures is adapted to the number of filter chambers 41. Preferably, the number of blocking structures is the same as the number of branch channels 46, that is, the blocking structures can correspond one-to-one with the branch channels 46 to control the opening or closing of the branch channels. Each second telescopic rod 81 is connected to the inner wall of the control channel 45. The telescopic end of the second telescopic rod 81 can drive the blocking member 82 to move to control the opening or closing of the inlet channel 47. In different embodiments, the method of controlling the opening or closing by the blocking member 82 can be flexibly selected based on the technical knowledge of those skilled in the art. For example, in this embodiment, the blocking member 82 can move along the length direction of the branch channel 46 and move to the left or right side of the inlet of the inlet channel 47 as required, thereby realizing the opening or closing of the inlet of the inlet channel 47.

[0042] The grinding unit further includes a motor 3. The motor 3 is installed on the grinding main body 1 to drive the grinding member 2 to operate. The grinding member 2 can be prepared from a grinding disc, and at least a part of it can extend outside the grinding main body 1 to grind the wall putty. The grinding main body 1 is provided with a handle 7, and a controller 31 for controlling the motor 3 to turn off or on is installed on the handle 7.

[0043] On the other hand, the present invention also provides a method for using a grinding device, including the following use steps: during grinding, the wall is ground by the grinding member 2; the power unit can suck the powder generated during grinding into the filtering part 4, and the sucked powder is intercepted by the intercepting structure 42.

[0044] The specific working process of this embodiment is as follows:

[0045] During use, a person holds the handle 7, aligns the grinding member 2 with the wall, and presses the switch of the controller 31. At this time, the output end of the motor 3 drives the grinding member 2 to rotate to grind the putty on the wall;

[0046] During grinding, the pump 5 is started, the first switching valve 43 and the second switching valve 44 are opened, and air and the powder generated during grinding are sucked into the suction tank 111. Then, they pass through the corresponding air ducts 112 and the connector 8 in sequence, and enter the filtration chamber 41 of the filtration unit 4 through the first switching valve 43. The powder and air are separated by the interception structure 42. The air can enter the interior of the pump 5 through the corresponding second switching valve 44, and finally be discharged to the external environment from the other end of the pump 5. The powder is separated on the filter plate surface of the interception structure 42, preventing the powder from entering the interior of the pump 5, avoiding damage to the pump 5, and ensuring the smooth progress of powder collection during grinding;

[0047] When it is necessary to clean the powder on the filter plate surface, the first switching valve 43 and the second switching valve 44 corresponding to the filter plate to be cleaned can be closed, while the first switching valve 43 and the second switching valve 44 of the other groups remain open. While cleaning, grinding and dust suction operations can still be carried out, ensuring the construction progress; in different usage scenarios, the closing and opening of each first switching valve 43 and second switching valve 44 can also be flexibly adjusted according to the operation and cleaning progress. The second telescopic rod 81 corresponding to the filtration chamber 41 to be cleaned can drive the plugging member 82 to move to open the entrance of the inlet passage 47, and the corresponding first telescopic rod 71 drives the push plate 72 to move to push the intercepted powder from the filter plate surface into the branch passage 46, and then be transferred to the discharge passage 48 through the inlet passage 47 and fall into the collection unit 6. The cleaned powder is transferred to the collection drawer 61 for storage. Then, the telescopic end of the first telescopic rod 71 drives the push plate 72 to reset, and the second telescopic rod 81 drives the plugging member 82 to reset, isolating the cleaned filtration chamber 41 from the collection drawer 61 again, so as to ensure that the cleaned filtration chamber 41 can carry out better dust suction work again;

[0048] When it is necessary to take out the powder in the collection unit 6, pull out the collection drawer 61 to take out the powder. After the powder is removed, reinstall the collection drawer 61 to fix the collection drawer 61 in the collection box.

[0049] This embodiment can prevent the powder from affecting the pump 5 after being absorbed, ensuring the use effect and service life of the grinding device; when it is necessary to clean the powder on the filter plate, cleaning and grinding and dust suction operations can be carried out simultaneously. Multiple groups of filtration units can switch work, which can not only ensure the powder absorption effect, but also ensure the construction progress; multiple dust suction channels are evenly distributed at intervals around the grinding member 2, and the powder generated during grinding can be absorbed from all directions, improving the powder absorption effect and reducing air pollution or health hazards to construction workers; the cooperation of multiple dust suction channels and multiple filtration chambers 41 can not only ensure the flexibility of the grinding device, but also reduce the suspension of the grinding device due to local blockage, ensuring the construction progress.

[0050] The embodiments of the present invention have been described in detail above. However, the above content is only the preferred embodiments of the present invention and should not be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
