[0036] In this embodiment, an adjustment channel is provided inside the filter section 4; in other embodiments, the adjustment channel can also be provided in the collection section 6, and the position of the adjustment channel can be flexibly adjusted according to the structural space of the device. The filter chamber 41 and the collection drawer 61 of the collection section 6 are respectively connected to the adjustment channel, and a sealing structure is provided in the adjustment channel to isolate or connect the filter chamber 41 and the collection drawer 61. The sealing structure can improve the flexibility of the grinding device and ensure the dust collection effect and construction progress.

[0037] In this embodiment, the sealing structure includes a second telescopic rod 81 and a sealing member 82, and the sealing member 82 is movably connected to the inner wall of the adjustment channel through the second telescopic rod 81.

[0038] The number of filter chambers 41 can be one or more. Preferably, in this embodiment, the number of filter chambers 41 is multiple. The filter section 4 is equipped with a number of matching switching valves to regulate the gas flow rate of the corresponding filter chamber 41. In this embodiment, a connector 8, a first switching valve 43, and a second opening valve 44 are also included. The number of first switching valves 43 and second switching valves 44 is the same as the number of filter chambers 41. The connector 8 is connected to the filter section 4. The first end of the connector extends into the interior of the grinding body 1 to form fluid communication with the dust suction channel. The second end of the connector is located inside the filter section 4. Each filter chamber 41 is located below the second end of the connector. This structure can better ensure that the powder is sucked into the filter chamber 41 by cooperating with the gravity of the powder. The valve body of each first switching valve 43 is installed at the second end of the connector, and the actuating end of the first switching valve 43 extends to the corresponding filter chamber 41. The valve body of each second switching valve 44 is connected to the filter section 4, and the second switching valve 44 is located below the filter chamber 41. The actuating end of each second switching valve 44 extends to the corresponding filter chamber 41, and each second switching valve is connected to the pump 5. In this embodiment, by cooperating with multiple switching valves, grinding and dust collection can be carried out simultaneously, and powder cleaning of part of the filter chamber 41 can also be performed at the same time, so as to better ensure the dust collection effect and construction progress.

[0039] In this embodiment, there are multiple suction channels, each of which can be connected to the filter chamber 41 via a connector. Preferably, each suction channel is connected to the first end of the connector. In different embodiments, the suction channels can be one or more of the following forms: suction grooves, air ducts, and suction pipes. They can be manufactured by various methods such as grooving, welding, or mechanical connection. The appropriate method can be flexibly selected based on the common technical knowledge of those skilled in the art, and this utility model does not impose any limitations. Multiple suction channels are spaced apart on the outer periphery of the grinding part 2 and are arranged in a circular pattern. In this embodiment, multiple suction grooves 111 are formed inside the grinding body 1 and on the outer periphery of the grinding part 2. A suitable number of air ducts 112 are formed inside the grinding body 1 and on the same side of the multiple suction grooves 111. The air ducts 112 correspond one-to-one with the suction grooves 111 and are interconnected. Each air duct 112 is connected to the filter chamber 41 via a connector 8. Multiple suction channels can improve the suction effect, allowing suction to be performed in different areas on the outer periphery of the grinding part 2, and can also reduce the risk of the grinding device becoming unusable due to blockage.

[0040] In this embodiment, the adjustment channel is formed by interconnecting the control channel 45 and the branch channels 46. The number of branch channels 46 is the same as the number of filter chambers 41 and they correspond one-to-one. A discharge channel 48 is provided at the lower interior of the filter section 4. The discharge channel 48 can be formed by a pipe and is connected to the collection tray 61. Each branch channel 46 is connected to the discharge channel 48 through an inlet channel 47, meaning the number of branch channels 46 is the same as the number of inlet channels 47 and they correspond one-to-one. The number of sealing structures matches the number of filter chambers 41. Preferably, the number of sealing structures is the same as the number of branch channels 46, meaning the sealing structures can correspond one-to-one with each branch channel 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 sealing 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 component 82 can be flexibly selected based on the technical knowledge of those skilled in the art. For example, in this embodiment, the blocking component 82 can move along the length of the branch channel 46 and move to the left or right side of the entrance to the channel 47 as needed, thereby opening or closing the entrance to the channel 47.

[0041] The sanding unit also includes a motor 3, which is mounted on the sanding body 1 to drive the sanding element 2 to operate. The sanding element 2 can be made of a sanding disc, and at least part of it can extend outside the sanding body 1 for sanding wall putty. The sanding body 1 is provided with a handle 7, on which a controller 31 for controlling the motor 3 to be turned on or off is mounted.

[0042] The present invention includes the following steps: during grinding, the wall is ground by the grinding component 2; the power unit can draw the powder generated during grinding into the filter unit 4, and the drawn powder is intercepted by the interception structure 42.

[0043] The specific working process of this embodiment is as follows:

[0044] When in use, the person holds the handle 7, aligns the sanding piece 2 with the wall, and presses the switch of the controller 31. At this time, the output end of the motor 3 drives the sanding piece 2 to rotate and sand the putty on the wall.

[0045] During grinding, pump 5 starts, and the first switch valve 43 and the second switch valve 44 open, drawing air and grinding powder into the suction tank 111. The powder then passes through the corresponding air passage 112 and connector 8 before entering the filter chamber 41 of the filter section 4 via the first switch valve 43. The powder is then separated from the air by the interception structure 42. Air can enter the pump 5 through the corresponding second switch valve 44 and is finally discharged to the external environment from the other end of the pump 5. The powder is separated on the surface of the filter plate of the interception structure 42, preventing it from entering the pump 5 and causing damage, thus ensuring smooth powder collection during grinding.

[0046] When it is necessary to clean the powder on the surface of the filter plate, the first switch valve 43 and the second switch valve 44 corresponding to the filter plate to be cleaned can be closed, while the first switch valves 43 and the second switch valves 44 of the other groups remain open. This allows for cleaning while simultaneously performing grinding and dust extraction, ensuring the progress of the work. In different usage scenarios, the opening and closing of each first switch valve 43 and the second switch valve 44 can be flexibly adjusted according to the work and cleaning progress. The second telescopic rod 81 corresponding to the filter chamber 41 to be cleaned can drive the sealing member 82 to move to open the entrance of the inlet channel 47. The corresponding first telescopic rod 71 drives the push plate 72 to move to push the intercepted powder from the surface of the filter plate into the branch channel 46, and then from the inlet channel 47 to the outlet channel 48, where it falls into the collection section 6. The cleaned powder is then transferred to the collection drawer 61 for storage. Then the extension end of the first telescopic rod 71 drives the push plate 72 to reset, and the second telescopic rod 81 drives the sealing part 82 to reset, so as to isolate the cleaned filter chamber 41 from the collection drawer 61 again, so as to ensure that the cleaned filter chamber 41 can perform good dust collection again.

[0047] When it is necessary to remove the powder from the collection section 6, pull out the collection tray 61 to remove the powder. After the powder is removed, reinstall the collection tray 61 to fix it in the collection box.

[0048] This embodiment avoids the impact of powder absorption on the pump 5, ensuring the effectiveness and service life of the grinding device. When it is necessary to clean the powder on the filter plate, grinding and dust collection can be carried out simultaneously. Multiple filter sections can be switched to work, ensuring not only the powder absorption effect but also the construction progress. Multiple dust collection channels are evenly distributed around the outer periphery of the grinding component 2, which can absorb the powder generated during grinding from all directions, improving the powder absorption effect and reducing air pollution or health hazards to construction workers. The combined use of multiple dust collection channels and multiple filter chambers 41 not only ensures the flexibility of the grinding device but also reduces the need for the grinding device to be shut down due to local blockage, ensuring the construction progress.

[0049] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made in accordance with the claims of this utility model should still fall within the patent coverage of this utility model.
