This left-right movement helps shake off dust adhering to its surface and interior, especially in areas difficult to remove with ordinary airflow, ensuring deep cleaning of the filter element. Combined with the automatic cleaning of the dust filter, this forms a highly efficient automatic cleaning system, minimizing the impact of dust on the entire air intake system, maintaining the optimal working condition of the entire air intake device, ensuring precise control of oil-air mixing, and improving the energy efficiency and reliability of the equipment.

[0023] In the air inlet process, the dust screen 301 can effectively intercept the larger dust, impurities and particulate matters in the air, and the filter element 304 has a larger filtering area and depth, which can more effectively intercept the fine dust and impurities in the air, keep the air inlet clean, and when the reciprocating wire rod 308 rotates on the front and rear sides, the sliding table 309 can drive the brush plate 310 to move up and down, so that the brush plate 310 can continuously remove the dust accumulated on the dust screen 301 during operation, maintain the air permeability and filtering efficiency of the dust screen 301, reduce the system performance degradation caused by filter screen blockage, and during the rotation of the reciprocating wire rod 308, the linkage shaft 311 is in a rotating state, so that the cam 312 can push the right linkage plate 305 to move, the spring 306 is compressed with the corrugated pipe 303, and the spring 306 can also reset, so that the surface of the right linkage plate 305 always adheres to the cam 312, so that the filter element 304 can move left and right.
