Working principle of toilet bowl

1. If you press the button, it will pull the chain in the toilet so that you can open the flush valve.

2. Then you will find that there is a lot of water in the water tank rushing to the toilet, thus flushing the toilet clean. At this point, the flush valve will return to its original position.

3. The impulse of water will start the siphon in the urinal, and the siphon will suck the dirt in the urinal into the drainage channel.

4. At the same time, the water level in the water tank will drop, and the floating block will also drop. The descending slider will open the water supply valve.

5. Water flows into the water tank and urinal through the water supply valve. When the water tank is filled with water, the floating block will float, and when the floating block reaches a certain height, the water supply valve will close.

6. If the toilet fails and the water supply valve cannot be closed, the overflow pipe can prevent the water in the water tank from overflowing.
