With the above method of advanced water intake, the following four adverse situations can occur:
1. the potential energy of the part of water filled in advance by the water inlet valve is smaller, the part of water is directly mixed with the original water in the water tank and is discharged from the water outlet, the original water discharge is increased, but the scouring effect caused by the increased water discharge is not obvious, and the water resource is wasted;
2. when the pipe diameter of the drainage pipe is smaller or the drainage pipe is blocked, the water inlet speed of the water inlet valve is probably larger than the drainage speed, and when the buoyancy of the floating barrel of the drainage valve is larger than the sum of the gravity of the floating barrel of the drainage valve and the suction force of the drainage pipe to the drainage valve sealing assembly, the floating barrel of the drainage valve is always in a floating state, so that the drainage valve cannot be normally closed, and water resources are continuously lost;
3. when the drainage valve is unable to be closed due to the fact that the drainage valve is continuously pressed or the button is blocked and cannot be reset, the water inlet valve is caused to continuously inlet water, and water resources are wasted;
4. when the drain valve is not closed, the water supplementing pipe led out from the water inlet valve starts to supplement water to the toilet bowl, so that the water supplementing pipe flowing to the toilet bowl can be washed away along with flushing water of the toilet bowl, the water supplementing sealing effect is not achieved, the flushing effect of the water supplementing pipe is hardly affected, and only the water is wasted due to the fact that the flushing effect is white.
