DETAILED DESCRIPTION

[0016] Reference Figure 1 and Figure 2 A self-cleaning system for a bus air conditioning filter comprises an air conditioning filter 1, an air cleaning module, a transmission module capable of moving the air cleaning module up and down along the surface of the air conditioning filter 1, and a dust collection module. The upper and lower ends of the air conditioning filter 1 are respectively fixed by an upper fixing plate 2 and a lower fixing plate 3. The air cleaning module is arranged on the surface of the air conditioning filter 1, the transmission module is installed on one side of the air conditioning filter 1, the air cleaning module is connected to the transmission module, and the dust collection module is installed at the lower end of a side of the air conditioning filter 1 away from the air cleaning module.
