Air filtering device of closed flight training simulation cabin

The invention discloses a closed air filtering device for a flight training simulation cabin, and relates to the technical field of air filtering. Wherein the cabin body is a closed simulation cabin; the movement assembly is fixedly connected to the outer bottom of the cabin; the system further comprises a head-mounted VR device, a pipeline, an air inlet filtering assembly and an air exhaust filtering assembly. A gas flowing channel is arranged in the head-mounted VR equipment; the pipeline is communicated with the cabin body and the head-mounted VR equipment; the air inlet filtering assembly is arranged in the pipeline and used for filtering external air and then conveying the air to the periphery of the head of the trainee, and an air curtain is formed at the mouth and nose of the trainee to prevent external air from entering. The exhaust filtering assembly is arranged in the pipeline and used for adsorbing air and impurities around the head of the trainee and discharging the air and impurities out of the c
