[0027] The dustproof component 5 includes a square baffle 51, a first dustproof component 52 is disposed on one side of the square baffle 51, and a second dustproof component 53 is disposed on one side of the first dustproof component 52;

[0028] The first dustproof component 52 includes a first motor 521, the output end of the first motor 521 is fixedly connected to a first rotating shaft 522, a first cam 523 is fixedly mounted on the first rotating shaft 522, a second cam 524 is fixedly mounted on the first rotating shaft 522, a filter screen vibration structure 525 is disposed on one side of the second cam 524, and a dustproof screen vibration structure 526 is disposed on the other side of the second cam 524;

[0029] The filter vibration structure 525 includes a filter 5251, four first sliding rods 5252 are fixedly installed on one side of the filter 5251, one end of the four first sliding rods 5252 is fixedly installed with a first limiting plate 5253, the four first sliding rods 5252 pass through the inside of the first spring 5254, and the four first sliding rods 5252 pass through the first fixed block 5255.

[0030] The dustproof net vibration structure 526 includes a first dustproof net 5261, and four second sliding bars 5262 are fixedly installed on one side of the first dustproof net 5261. The four second sliding bars 5262 pass through the inside of the second spring 5263, and the four second sliding bars 5262 pass through the second fixed block 5264. The second limiting plates 5265 are fixedly installed on one end of the four second sliding bars 5262.

[0031] The second dustproof component 53 includes a circular baffle 531 , a second dustproof net 532 is disposed on one side of the circular baffle 531 , and a cleaning brush 533 is disposed on one side of the second dustproof net 532 .

[0032] During use, the air entering the frequency conversion cabinet 1 first passes through the square baffle 51 to filter out large particles, then passes through the first dustproof net 5261 to filter out most of the dust, and then passes through the filter net 5251 to further filter the dust. At the same time, the first motor 521 drives the first cam 523 and the second cam 524 on the first rotating shaft 522 to rotate, and the first cam 523 and the second cam 524 intermittently push the first dustproof net 5261 and the filter net 5251. When the filter net 5251 is pushed, one side moves along the four first sliding bars 5252 and then squeezes the first spring 5254, so that the first spring 5254 generates tension.

At the same time, at the vent on the other side of the frequency conversion cabinet 1, air enters the vent first through the circular baffle 531, and then through the second dustproof net 532, so as to prevent dust from entering the frequency conversion cabinet 1, and the second motor 61 will drive the cleaning brush 533 to clean the second dustproof net 532 to prevent the second dustproof net 532 from being blocked, thereby preventing dust and mosquitoes from entering the frequency conversion cabinet and falling between the internal electrical appliances, making it less likely to cause short circuits, etc., which can not only avoid electrical failures, but also avoid fires caused by short circuits and ultimately fires. At the same time, a collection and cleaning drawer 7 is provided under the first dustproof component 52 and the second dustproof component 532 to collect fallen dust, and then the drawer is pulled out for easy dust cleaning.
