What is the structure of a flush toilet?

As shown in the experiment, when the coarse straw is placed over the thin straw and inserted vertically into the water and raised slightly, the coarse and thin straws form a special siphon, and the water continues to flow down the thin pipe. Flush toilets also make use of the principle of siphons.

Water enters the water tank through the pipe that is installed with angle valve, and with the continuous rise of the level, the float will be lifted together, and when the float reaches a certain height, it will be closed and entered the pipeline (mainly sealed by the water-stop rubber ring shown in the figure), and the water tank will no longer be replenished with water at this time. When the flush handle is pressed, the water stop rubber at the bottom of the tank is pulled to open and the water enters the toilet seat. The specific pumping principle is as follows:

Flush toilet flushing.

It refers to the S-shaped bend under the toilet, and when the water surface in the toilet exceeds the high point of the S-bend, the siphon phenomenon is formed, which can pump the water and dirt of the toilet together. Until only a small amount of water remains, the siphon destroys, leaving a small amount of water, forming a water seal.
