[0002] An air compressor is a device used to compress air. With the continuous development of social science and technology and the continuous expansion of the industry scale, air compressors have also been widely used, including food, pharmaceutical industry, coal blasting and tire inflation and other industries. Air compressors need to inhale a large amount of air during operation. The air contains various impurities such as dust. When the air compressor prepares gas, directly injecting air will cause large particles of dust to hit the blades and air flow channels, increase the wear of the internal components of the air compressor, and affect the operating performance of the equipment. For this reason, a filter device is usually installed at the air inlet end.

[0003] Although some existing filtering devices can filter the gas at the air intake end of the air compressor, after long-term use, a large amount of dust remains on the surface of the filter, causing the filter mechanism to be blocked, reducing the air intake of the air compressor and making it difficult to clean the filter.
