The sensor in the urinal in the men's toilet is called the infrared sensor, also known as the thermal infrared human body sensor, which is developed according to the principle of infrared reflection and belongs to an intelligent water-saving and energy-saving equipment. Including sensor faucets, automatic hand dryers, medical hand washing devices, automatic soap dispensers, sensor urinal flushes, sensor toilets, etc., are all products that use infrared sensors.
The working principle of the infrared sensor: when the human hand or a certain part of the body is in the infrared area, the infrared rays emitted by the infrared emitting tube are reflected to the infrared receiving tube due to the human hand or body blocking, and the signal processed by the microcomputer in the integrated circuit is sent to the pulse solenoid valve, and the solenoid valve receives the signal and opens the valve core according to the specified instruction to control the head water; When the human hand or body leaves the infrared sensing range, the solenoid valve does not receive a signal, and the solenoid valve core is reset by the internal spring to control the water shut-off.
Look at what caused the blockage, paper and the like can be washed away with a few clicks of the leather and the like, and hard objects are more troublesome, so you can only find a professional dredger.
