The sensing principle of the automatic flushing squatting toilet is mainly based on the principle of infrared reflection. When someone is using a squatting toilet, the human body will block the infrared rays emitted by the infrared emitting tube, so that the infrared rays cannot be reflected to the infrared receiving tube. When a person leaves the squatting toilet, the infrared rays are reflected to the receiving tube, which sends the signal to the microcomputer processing chip. After the microcomputer processing chip processes the signal, it sends a command 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 water output of the machine.
Specifically, the main components of an automatic flush squat toilet include:
1.Infrared emitter and receiver tube: The transmitter tube emits infrared light, and the receiver tube receives the reflected infrared signal.
2.Microcomputer processing chip: Receives and processes infrared signals, determines whether someone is using a squatting toilet, and controls the switch of the solenoid valve.
3.Pulse solenoid valve: control the switch of the flush valve according to the instructions of the microcomputer processing chip.
4.Disc and outlet: The disc controls the outflow of water, and the outlet is the outlet of the water.
5.Water level port and seal port: The water level port is used to determine the height of the water level, and the seal port is higher than the water level port to ensure that water does not overflow from the water outlet.
6.Water inlet: The water inlet is used to supply water to the squatting toilet**.
When the infrared rays of the human body are reflected to the receiving tube, the microcomputer processing chip will determine that someone is using a squatting toilet and send instructions to the pulse solenoid valve, so that the solenoid valve opens the valve core and allows water to flow out of the outlet for flushing. When the person leaves, the infrared rays are no longer reflected to the receiving tube, and the microcomputer processing chip judges again and sends instructions to the solenoid valve to close the valve core and stop flushing.
