Lets talk about how the flush toilet works

How the toilet works: Control the drain and water storage with a drain knob and plug. When using, turn the drain knob and pull up the water plug with a metal rope or nylon rope connected to the water plug, the water plug is pulled up from the outlet pipe mouth, and the water outlet pipe discharges the water into the urinal. Using the kinetic energy converted from the weight and potential energy of the water, the secreted dirt is flushed into the sewer pipe.

      When the water level drops to a certain height, the negative pressure generated by the gravity of the water will press the water plug back into the outlet, blocking the outlet. At this time, no water is drained, and a new water storage stage is started; When the water level drops and flushes the urinal, due to the drop in water level and the gravity of the float drives the lever, the float and lever flip the water replenishment mechanism and start to replenish water synchronously.

       During the replenishment phase, the buoyancy of the float and the lever are used to control the replenishment of the tank. When the float ball drops to the lowest position, the water plug enters and exits the water pipe hole under the action of negative pressure, and the water tank begins to store water; The inlet pipe is connected to the water supply pipe and is responsible for the input of the water source. When the water replenishment reaches a certain height, the buoyancy of the water distributor lifts the float, and the linkage rod closes the water replenishment mechanism and stops the water replenishment.

      When the inlet pipe leaks due to failure (such as the inlet pipe plug cannot be blocked or the inlet pipe is broken, etc.), the water level in the water tank will continue to rise and overflow the water tank. The setting of leaking pipes solves this problem. When the water level rises to the seepage pipe hole, the water will flow from the seepage pipe into the toilet bowl and will not overflow the tank. When the inlet pipe is working properly, the water surface inside the tank will not reach the outlet of the leaking pipe, so there is no need to worry about the water flowing away.
