The other end of the filter element 4 is provided with an air outlet. The bottom cover 2 is fixed on the air inlet of the air compressor and is provided with an air outlet hole 22 communicating with the air inlet. The bottom cover 2 is also mounted on the opening 13 of the protective cylinder 1, so that the bottom cover 2 abuts against the end of the filter element 4 provided with the air outlet, and the air outlet hole 22 also communicates with the air outlet. The connecting screw rod 5 is fixed on the bottom cover 2 and passes through the connecting through hole 43 and the connecting hole 14. The connecting nut 3 is mounted on the connecting screw rod 5 and located at the top of the protective cylinder 1, for pressing the filter element 4 in the protective cylinder 1 through the connecting screw rod 5 and the bottom cover 2.

[0024] When disassembling the filter element 4, the connecting nut 3 is unscrewed, and then the protective cylinder 1 is rotated, so that the filter element 4 can be taken out. Then the filter element 4 is directly inserted onto the connecting screw rod 5, and then the protective cylinder 1 is inserted onto the filter element 4, and the connecting screw rod 5 passes through the connecting hole 14, and then the connecting nut 3 is tightened to complete the fixation of the protective cylinder 1. The disassembly is convenient, and the replacement of the filter element 4 is convenient and simple. Since the two ends of the filter element 4 are pressed by the connecting screw rod 5 and the connecting nut 3, the filter element 4 has reliable pressing force, so that the end of the filter element 4 provided with the air outlet can be always pressed on the bottom cover 2, and can effectively prevent loosening, thereby avoiding air leakage.
