With reference to 1 - 9 it is the second embodiment of the present invention based on the previous embodiment.

Specifically, the water back member 201b includes a primary water back hole 201b-1 and a secondary water back hole 201b-2, wherein the secondary water back hole 201b-2 is located below the primary water back hole 201b-1.

It should be noted that the primary water back hole 201b-1 is a square hole and provided with two; wherein the secondary water back hole 201b-2 is a round hole and is provided with three layers, each layer being spaced apart by a smaller distance; wherein the distance between the primary water back hole 201b-1 and the secondary water back hole 201b-2 is much larger than the distance of the round hole in each layer of the secondary water back hole 201b-2.

The drain element 201d further comprises a drain rod 201d-1, a water stop ring 201d-2 and a drain column 201d-3, the water stop ring 201d-2 being located below the drain rod 201d-1, the drain column 201d-3 being above the water stop ring 201d- 2 located; wherein the drain column 201d-3 includes a drain rod hole 201d-3a and a drain hole 201d-3b, the drain rod hole 201d-3a being located above the drain hole 201d-3b.

It should be noted that during the upward movement of the water stop ring 201d-2, the surface with which the drain hole 201d-3b and the drain line 102c are connected, gradually increases and the drain speed increases with increasing connection area.

Third embodiment

With reference to 1-11 it is the third embodiment of the present invention based on the previous embodiment.

Specifically, the force-guiding element 202b comprises a force-guiding seat 202b-1, a second spring 202b-2, a force-receiving block 202b-3 and a force-guiding rod 202b-4, wherein the second spring 202b-2 is located in the force-guiding seat 202b-1, wherein the force-receiving block 202b-3 is located on the side of the second spring 202b-2, and the force guide rod 202b-4 is located on the side of the force receiving block 202b-3.

It should be noted that the power guide seat 202b-1 is provided with an inlet hole; wherein the second spring 202b-2 is attached at one end to the force guide seat 202b-1 and at one end to the force receiving block 202b-3; wherein the force guide rod 202b-4 is articulated to the force guide seat 202b-1.

Further, the force receiving block 202b-3 includes an inlet stop 202b-3a, a connecting block 202b-3b and a second connecting pin 202b-3c, the connecting block 202b-3b being on one side of the inlet stop 202b-3a, and the second connecting pin 202b -3c is located on one side of the connection block 202b-3b.

It should be noted that the outer diameter of the cross section of the inlet stop 202b-3a is the same as the inner diameter of the inlet conduit 102a; wherein the connection block 202b-3b is slidably connected to the second spring 202b-2; wherein the connection block 202b-3b is slidably connected to the force guide seat 202b-1; wherein the second connecting pin 202b-3c has two pin holes.

Optimally, the force guide rod 202b-4 includes a first joint column 202b-4a and a second joint column 202b-4b, with the second joint column 202b-4b located on one side of the first joint column 202b-4a.

In this embodiment, when the flow rate of the water entering the water storage tank 101b through the inlet pipe 102a is too high, the water entering the water storage tank 101b through the inlet pipe 102a flushes away the inlet stopper 202b-3a, thereby compressing the second spring 202b-2 , and the degree of compression of the second spring 202b-2 increases with the flow rate of the incoming water; When the inlet stop 202b-3a is washed away, the second connecting pin 202b-3c moves away from the inlet conduit 102a, which in turn drives the force guide rod 202b-4 to push the slider 202a-3 back into the spring resistance seat 202a-1 so that the rounded sliding head 202a-3b is no longer slidably connected to the release rod 201d-1; At this point, the water stop ring 201d-2 is no longer limited by the rounded sliding head 202a-3b and can move up faster within the drain column 201d-3 under the buoyancy force of the floating block 201a when the water level in the water storage tank 101b is too high, thereby the drain hole 201d-3b can reach the maximum drain speed more quickly.
