How does a flush toilet work?

The "pumping" of the flush toilet 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.

The different forms of tanks, which are only set up to supply a certain amount of water, do not mean "pumping".

The pressure difference created by the water's own weight is used to "suck" water into the pipe. It's not a siphon phenomenon. The S-bend also has the function of "water sealing" to prevent the sewage in the pipe from being discharged into the room.

Like tornadoes, vortices are formed, creating a large suction.

Water pressure problem. The teacher said it before, but I forgot it.

It's good to take it apart and see it yourself.。。。

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.

How it works, how the toilet works.
