[0026] The working principle of the utility model is as follows: when it is necessary to clean the dust generated by grinding, the dual-axis motor 9 can be started to drive the crankshaft 10 and the fan blades 11, thereby generating a suction force, and cooperating with the dust hood 8 to suck the dust into the air duct 6. At the same time, the crankshaft 10 will drive the push rod 14 through the connecting piece 13 and then drive the piston 16 to reciprocate left and right, so that the piston 16 pushes the water entering the pump barrel 15, so that the water is transported to the two water spray pipes 17 and sprayed out through the nozzles, and the dust-containing air entering the air duct 6 will first be treated by the water sprayed by the water spray pipe 17 on the right, and then filtered by the two filter screens 12, and then be treated by the water sprayed by the water spray pipe 17 on the left.

At the same time, the water sprayed by the water spray pipe 17 will also intercept and process some of the dust that falls due to the knocking. In addition, the movement of the push rod 14 will also drive the two extrusion rods 25 to move left and right synchronously through the support rod 26, so that the extrusion surface at one end of the support rod 26 is in contact with the inclined surface at the lower end of the knocking piece 24 and gradually squeezes it upward, so that the knocking piece 24 hits the filter screen in the filter frame 18 and vibrates, thereby avoiding the accumulation of collected dust and clogging the filter screen, avoiding affecting the filtering effect, and being easy to use; and when the filter frame 18 needs to be disassembled, the screw 27 can be twisted to move the blocking rod 28 away from the side of the filter frame 18, so that it can be separated from the side of the filter frame 18 in the connecting seat 29, and then it can be removed. The blocking rod 28 is moved out to the outside of the connecting seat 29, and then the connecting seat 29 can be pulled to bring the filter frame 18 out, thereby disassembling it, and the dust collected in the filter frame 18 can be processed or cleaned. When installing the filter frame 18, the filter frame 18 can be installed in the corresponding slot, and then the screw 27 can be twisted to drive the blocking rod 28 to rotate, so that the blocking rod 28 moves into the connecting seat 29. After the connecting seat 29 limits the blocking rod 28, the screw 27 can be continued to be rotated so that the screw 27 drives the blocking rod 28 to move toward the side close to the filter frame 18, so that the blocking rod 28 squeezes the connecting seat 29 to limit and fix the filter frame 18, and the installation and fixation of the filter frame 18 is completed. It is easy to use and more practical.
