Principle of Mobile Toilet Water-Saving Devices
The principles of mobile toilet water-saving devices vary depending on the type, mainly falling into the following categories:
Toilet water savers are primarily composed of infrared sensing detectors, microcomputer program controllers, and low-voltage DC solenoid valves, operating based on the principle of infrared human body sensing. When someone moves in front of the detector, it captures the infrared signals emitted by the human body and rapidly transmits them to the microcomputer program controller. After receiving the signals, the microcomputer program controller processes them through internal programming and controls the solenoid valve to open, thereby enabling water release. This device can automatically control water flow based on human activity, avoiding unnecessary water waste.
The core design of waterless mobile toilets lies in completely breaking away from the hydraulic conveyance chain, with a working principle more akin to a closed biochemical treatment unit. From the perspective of material processing pathways, it first separates the solid and liquid components of excrement through physical separation technology. The solid portion is sent to a sealed container with a special coating for treatment, while the liquid portion is directed to independent evaporation or purification devices. These devices do not rely on external water sources, completing water evaporation solely through airflow or small-scale energy drives, with residual concentrates safely disposed of. In terms of chemical conversion, waterless mobile toilets employ composite treatment agents, with a synergistic system composed of multiple components reacting under normal temperature conditions, eliminating the need for additional heating devices and further reducing energy consumption.
The working principle of intelligent water-saving mobile toilets is mainly based on sensors and control systems. When someone enters the toilet, infrared sensors detect the presence of the human body and transmit signals to the control system. The control system then controls the activation and water volume of the flushing device according to preset programs and parameters. For example, it automatically performs a small-volume flush after urination and an appropriate flush after defecation based on the situation. Additionally, the toilet is equipped with a sewage treatment system internally, which performs preliminary treatment and purification of sewage, improving the recycling rate of water resources.
Trough toilet water savers utilize infrared sensing and microcomputer control technology to achieve an intelligent management mode of 'flushing more when there are more people, flushing less when there are fewer people, and not flushing when there is no one'. They employ two-stage delay control technology, triggering a 20-30 second flush after sensing human signals and forcibly shutting off the water flow for 1 minute. Different models of water savers vary in their water-saving rates. For instance, the HP2004-S2 model achieves a water-saving rate of over 85% in toilet bowls, while the S1 model employs locking time technology in urinals to achieve a water-saving rate of over 95%.
