Mobile Toilet Water-Saving Device

The mobile toilet water-saving device is a device that achieves efficient water conservation through intelligent sensing control and is widely used in the renovation of public toilets in public places.

Core Components and Working Principle

The mobile toilet water-saving device typically consists of an infrared sensing detector, a microcomputer program controller, and a low-voltage DC solenoid valve. The infrared sensing detector detects human activity and transmits the signal to the microcomputer program controller, which controls the opening and closing of the solenoid valve according to preset logic, achieving automated management of "flushing when someone is present and stopping when no one is present". For example, in trough-type public toilets, the solenoid valve and infrared sensor work in tandem to precisely control the flushing timing, avoiding the water waste associated with traditional timed flushing modes.

Technical Features and Advantages

1. Intelligent Adjustment of Flush Volume: The device can dynamically adjust the flush volume based on usage frequency. It increases the flush volume during high traffic periods and decreases it during low traffic periods, achieving a water-saving efficiency of 30%-90%. Typical cases show that after installation, the average daily water consumption of public toilets drops from 14.4 tons to 2.5 tons, demonstrating significant water-saving effects.
2. Environmental Adaptability: The normal operating temperature range is 1~45℃. In extreme cold conditions (ambient temperature below -1℃), an anti-freeze protection mechanism is automatically activated to prevent pipe freezing and ensure stable device operation.
3. Easy Installation and Maintenance: The infrared probe should be aligned with the direction of the toilet trough, and the recommended wall-mounted height of the main unit is not less than 2.4 meters to avoid human damage. Daily maintenance mainly involves cleaning the filter screen of the solenoid valve, which is simple and low-cost.
4. Functional Expandability: High-end models support digital parameter adjustments (such as flushing time and sensing sensitivity), remote control, and siphon-type water tank circulation flushing design, further optimizing water-saving effects and management efficiency.

Typical Application Scenarios

This device is suitable for the renovation of public toilets in public places such as schools, stations, and shopping malls. For example, the trough-type water-saving device provided by Nanchang Jinghui Energy-Saving and Environmental Protection Technology Co., Ltd. achieves unattended automatic management through the linkage of the solenoid valve and infrared sensor, with a typical investment recovery period of 1-6 months, offering both economic and social benefits.

Conclusion

The mobile toilet water-saving device effectively solves the problem of water waste in traditional public toilets through intelligent control and modular design, while possessing advantages such as strong environmental adaptability and low maintenance costs, making it an ideal choice for water-saving renovations in public places.
