More Information
Summary:The utility model relates to a vehicle toilet air circuit valve control system, which comprises a flushing electromagnetic valve, a closestool air valve, a flushing switch, a DC power supply, and a high-pressure air port; the vehicle toilet air circuit valve control system is characterized in that an air circuit main electric control valve is connected with the high-pressure air outlet of the air circuit in series, and the control circuit of the main electric control valve is connected with a delay circuit. The vehicle toilet air circuit valve control system solves the air leakage problem of the vehicle toilet air circuit valve control system. Observed from the water, the air leakage volume is reduced from 5 to 10 bubbles per minute to 1 bubble per hour. The impact of the vehicle toilet blowdown system on normal operation of the entire vehicle air circuit system is reduced, and the vehicle toilet quality is improved.
