The heavier impurities will fall into the ash hopper 13, while the lighter impurities adhere to the periphery of the filter element 3. When there are many impurities attached to the periphery of the filter element 3, the electromagnet 704 is energized, so that the electromagnet 704 attracts the iron block 703, thereby moving the partition 702 upward and compressing the spring 701. Then the electromagnet 704 is de-energized, and the electromagnet 704 cannot attract the iron block 703. The spring 701 resets the partition 702, so that the air under the partition 702 is pressed into the interior of the filter element 3, thereby back-blowing the filter element 3, removing impurities on the outer surface of the filter element 3, and restoring the ventilation volume of the filter element 3.

[0019] The cleaning mechanism 7 includes a spring 701, a partition 702, an iron block 703, an electromagnet 704 and a through-port 705.

[0020] A glass 10 is provided in the middle of the sealed door 8, and a handle 9 is provided on the right side of the sealed door 8.

[0021] Working principle:

[0022] The air pump 4 draws air filtered by the filter element 3 from the middle of the shell 1 through the air inlet pipe 5, so that the outside air enters the shell 1 through the air intake pipe 6 along with the dust generated during the carbon brush processing, and then filters the air through the filter element 3. The heavier impurities will fall into the ash hopper 13, while the lighter impurities will adhere to the outer periphery of the filter element 3. When there are many impurities attached to the outer periphery of the filter element 3, the electromagnet 704 is energized so that the electromagnet 704 attracts the iron block 703, thereby moving the partition 702 upward and compressing the spring 701. Then, the electromagnet 704 is de-energized so that the electromagnet 704 cannot attract the iron block 703, and the spring 701 resets the partition 702, thereby pressing the air under the partition 702 into the filter element 3, thereby back-blowing the filter element 3, removing impurities on the outer surface of the filter element 3, and restoring the ventilation volume of the filter element 3.
