The elastic pad 42 made of silica gel has good elasticity, stable property and durability, and is beneficial to prolonging the service life. It will be appreciated that the resilient pad 42 may be a resilient pad of other materials.
As shown in fig. 3, the elastic member 50 is used for providing a restoring driving force for the movable core 30, and when the movable core 30 moves relative to the water bladder 20, the elastic member 50 is compressed to provide a restoring driving force for the subsequent movable core 30.
Further, the elastic member 50 may be a spring, a spring plate or an elastic rubber block. For example, in the present embodiment, the elastic member 50 is a spring that is sleeved on the movable core 30. The spring is located in the movable chamber 212.

The inlet fitting 60 is a three-way fitting that connects between a water source (which is the water flow released from the tank), the inlet 213 and the burst valve of the tank. When the water tank releases water flow, the water flow enters the flushing pressure loss prevention assembly 100 and the burst valve at the same time, and the water pressure for triggering the burst valve is larger than the water pressure for pushing the movable core 30 to seal the overflow hole 11, so that the burst valve is started after the overflow hole 11 of the overflow pipe is sealed. It will be appreciated that in other embodiments, the flush pressure loss prevention assembly 100 and the burst valve may be separately connected to a water source.
When the water tank is flushed, the water flow released from the water tank enters the water inlet cavity 211 from the water inlet 213 of the water bag 20 as a water source, the elastic separation block 22 and the elastic member 50 start to deform under the action of the water pressure of the water flow, the water inlet cavity 211 is enlarged, the movable cavity 212 is contracted, the movable core 30 moves towards the overflow hole 11, and the sealing member 40 seals the overflow hole 11 to seal the overflow opening of the overflow pipe, so that the water flow in the flushing pipe 300 cannot be discharged from the overflow opening of the overflow pipe, and the pressure loss during flushing is reduced. When the water tank is flushed, the water flow pressure at the water inlet 213 is reduced, the movable core 30 and the elastic separation block 22 are reset under the driving of the deformation force of the elastic member 50, the water in the water inlet 211 is extruded, the water inlet 211 and the movable cavity 212 recover to the initial form, and the sealing member 40 leaves the overflow hole 11 along with the reset of the movable core 30, so that the overflow pipe, the overflow hole 11 and the overflow gap 23 are communicated, and the normal overflow function is achieved. Through the design, when the water tank is flushed, the water flow released by the water tank is used as driving force to push the movable core 30 to move so as to drive the sealing piece 40 to seal the overflow hole 11, so that the water flow in the water flushing pipe of the water tank cannot overflow to the outside from the overflow hole of the overflow pipe, the pressure loss during flushing is reduced, and the cleaning effect is improved.
