The principle is to use buoyancy to control the water level. There is a float in the flushing tank, and when the water level rises, the float will rise with it, and when the water level drops, the float will fall with it.
With this simple device, we can control the valve on the intake pipe, and thus control the inflow and outflow of water.
When the water level rises and the float rises, the valve on the intake pipe closes and water begins to flow into the urinal.
When the water level drops, the float drops, the valve on the intake pipe opens, and water begins to flow out of the urinal. In this way, the flushing tank automatically keeps the urinal clean and hygienic.
1. The public toilet flushing tank is controlled by the gravity tank and the float ball or float rod mechanism inside the tank to control the water output and close the water flow.
2. The specific principle: pulling the handle of the flush device will make the water inside the tank flow out of the water pipe, and then flow into the toilet to wash away the dirt.
At this time, the water level drops, the float ball or float rod will move down with the drop of the water level, and finally contact the mechanism of the water valve, so that the water valve is closed and the water is stopped.
3. There are some auxiliary designs for the flushing tank, such as the design of the drainage valve and the capacity of the tank, which will affect the flushing effect and the flushing time.
The principle of public toilet flushing water tank is that when the human hand or a part of the body is in the infrared area, the infrared emitted by the infrared transmitting tube is reflected to the infrared receiving tube due to the human hand or the body's product block, and the signal processed by the microcomputer in the integrated line is sent to the pulse solenoid valve, which receives the signal and opens the valve spool according to the specified instructions to control the head water; When the human hand or body leaves the infrared sensing range, the solenoid valve does not receive the signal, and the solenoid valve spool is reset by the internal spring to control the water off
The working principle inside the water tank: the water level in the water tank is controlled by the float water switch, that is, the float stops the water as the water level in the water tank rises and rises, and falls into the water; When someone is flushing, press the button ---- to pull out the rubber plug at the bottom of the tank. The water in the tank will rush out immediately, and the rubber plug will be rushed back to the drain port at the bottom of the tank by the water at the bottom of the tank, blocking the drain port. Meanwhile, the supplementary water will also enter the high water level, and the work will continue over and over again.
