Anonymous users2024-01-24The working principle of the passive infrared probe: the automatic flush is equipped with an infrared receiving probe, when the human body is approaching, the probe can receive the infrared rays emitted by the human body of sufficient strength, the control circuit moves to make the flushing solenoid valve energized and kept for two seconds, put water once, when the person leaves, the infrared rays received by the probe are reduced, the internal control circuit is reset, and at the same time, keep the solenoid valve connected for three seconds, and then release the water again.
The working principle of the active infrared probe is adopted: the probe sends out a modulated infrared pulse signal of a certain frequency by itself, and at the same time can selectively receive the infrared rays emitted by itself and reflected back by the object, and the infrared light of other frequencies will not act when the probe is irradiated. This method can resist the interference of heat sources such as sunlight and heating, and work more reliably.
When the modulated infrared pulse reflected back by the human body or other objects close to the probe is strong enough, the internal control circuit moves to flush the water once, and when the modulated infrared wave reflected back by the person or object leaves the weakened, the circuit resets and flushes again, and the control process is the same as that of the passive type.
The time of each flush can be adjusted as needed.

Anonymous users2024-01-23The questions are vague and specific. Simple urinal, there is a float in the water tank, when the water is filled with the design position, the float floats up to block the water inlet pipe, and drives the bottom valve connected to the other end, when the water is drained, the float falls, the bottom valve closes the water storage, and the circulation --- the induction principle of the advanced urinal.

Anonymous users2024-01-22Simple, infrared sensing principle
All use a floating controller to switch the water source on and off. The old-fashioned use of floats.
You mean to take a look at the plumbing and plumbing market, it's rare now.
The principle of automatic flushing of toilets:
There is a float valve inside, as the water level in the tank rises, the buoyancy generated by the float increases, and when the water level rises to a predetermined value, the buoyancy generated by the float will be transmitted to the plug that discharges the water through a seesaw structure, and the plug can be automatically pulled up as long as the drain button is pressed. After the water is discharged, the plug automatically returns to its position under the action of the spring and enters the next round of water filling cycle. >>>More
General principle: It is composed of infrared induction circuit, control circuit, solenoid valve motor drive circuit. >>>More
Hello. It is an automatic flush controlled by the clutch. >>>More
