[0021] The upper and lower ends of the left conversion device 36 and the right conversion device 35 are both provided with independently controllable valves.

[0022] Under external air pollution or nuclear, biological and chemical battlefield conditions, the gas filtering and ventilation device switches to the gas filtering and ventilation state after receiving the three-defense alarm signal, and uses the dust removal function of the booster fan 27 to remove large particles of dust in the contaminated air, and then uses the fine filter unit of the gas filter canister 26 to filter out the particles, toxic smoke, toxic mist, biological warfare agent aerosols, and radioactive dust in the air. Finally, the gas filter unit of the gas filter canister effectively filters out the toxic agent vapor in the contaminated air through physical adsorption and chemical adsorption, and finally the clean and non-toxic air is sent into the closed compartment to form overpressure, thereby ensuring that the vehicle is not contaminated by nuclear, biological and chemical warfare agents and personnel are not harmed.

[0026] When cleaning and ventilating, Figure 3 The cleaning ventilation cycle process is: gas in the car → exhaust duct 8 in the car → the upper valve of the right conversion device 35 is closed and the lower valve is opened, the upper valve of the left conversion device 36 is opened and the lower valve is closed → the booster fan 27 is started → inlet and outlet duct 13 → outside the car.
