At this time, the air compressor 2023 draws the air inside the air inlet 2021 into the air compressor 2023 for pressurization. After the pressurized air is cooled by the cooler 2024, the two-position five-way solenoid valve 2027 on the surface of the air inlet pipe 2026 is opened, so that the air is introduced into the molecular sieve tower 2025 for oxygen and nitrogen separation.
