The overflow cap 1 comprises a drainage part 11 and a water inlet part 12 fixedly arranged above the drainage part 11, and a drainage channel 110 which is communicated up and down is arranged in the drainage part 11. The water inlet portion 12 is an annular support body, the bottom of the annular support body is fixed on the outer wall surface of the water discharging portion 11, and the side edge of the annular support body is provided with a water inlet 100 communicated with the water discharging channel 110. The inner wall surface of the annular support body surrounds to form an accommodating space 10, the solid floater 21 is arranged in the accommodating space 10 and can move up and down, and the bottom of the solid floater 21 is in sealing fit with the top of the drainage channel 110. The top of the ring-shaped support body is provided with a limit structure for limiting the floating stroke of the solid floater 21.

The annular support body comprises a plurality of guide ribs 101 uniformly distributed along the circumferential direction of the outer wall surface of the drainage part 11 and a fixing ring 102 fixedly arranged at the top of the guide ribs 101, and the bottoms of the guide ribs 101 are fixedly connected with the outer wall surface of the drainage part 11 through connecting parts 103. The connecting portion 103 is positioned lower than the top end surface of the drain portion 11. The guide ribs 101, the connecting portion 103, the fixing ring 102 and the drain portion 11 are integrally formed.

The limit structure is fixed on the inner wall surface of the fixing ring 102, and the limit structure comprises a plurality of semicircular limit bosses 104 which are uniformly distributed along the circumferential direction of the inner wall surface of the fixing ring 102.

The side wall of the water outlet of the base of the drain valve is not provided with an overflow channel. In the initial state, the solid float 21 is in the closed state due to gravity. When the water inlet valve 3 works, two streams of water are injected into the water tank 5, and the other stream of water is injected into the overflow pipe 40 through the water replenishing pipe 30 and enters a closestool pipeline through a water outlet of the valve base to realize the water replenishing function. When the water inlet valve 3 does not stop water and water is continuously fed, the water tank 5 overflows, when the water level of the water tank 5 rises and overflows the solid floater 21 for a certain height, the solid floater 21 starts to float upwards, water flows into the overflow pipe 40 from an overflow port, and the water flows to a toilet pipeline through the overflow pipe 40 to realize overflow.

Example two

As shown in fig. 9-11, the present embodiment differs from the first embodiment only in that: the flow guide tube 105 is not provided on the side of the drain part 11, and the water storage branch pipe 106 and the water replenishing elbow joint 107 are not provided inside the drain passage 110. The rest of the structure and principle of the embodiment are the same as those of the first embodiment.

EXAMPLE III

As shown in fig. 12 to 17, the present embodiment differs from the first embodiment only in that: the floating bodies are floating pontoons 22, and the floating pontoons 22 can be of a top opening structure (as shown in fig. 15) or a bottom opening structure (as shown in fig. 16 and 17). The bottom is fixedly provided with a sealing rubber pad mounting part 220, and a sealing rubber pad 6 which is used for being matched with the top of the drainage channel 110 in a sealing way is fixedly mounted on the sealing rubber pad 220 mounting part. The float bowl 22 is arranged in the accommodating space 10 and can move up and down, a plurality of abdicating grooves 221 matched with the limiting bosses 104 in shape are formed in the outer wall surface of the float bowl 22 at the positions corresponding to the limiting bosses 104, and the abdicating grooves 221 penetrate through the float bowl 22 up and down. The rest of the structure of the present embodiment is the same as that of the first embodiment.

When the buoy 22 is installed, the receding grooves 221 on the buoy 22 are respectively aligned to the limiting bosses 104, and the buoy 22 is installed in the accommodating space 10 and then rotates by a certain angle, so that when the buoy 22 floats upwards, the limiting bosses 104 can limit the buoy 22.

Normally, the float 22 is in a closed state due to gravity, and the sealing rubber pad 6 installed at the bottom of the float 22 is in sealing fit with the top of the drainage channel 110, so as to isolate the drainage outlet of the drainage valve from being communicated with the outside air. At the same time, the float 22 is in a closed position due to gravity. When the water level rises and overflows the floating pontoon 22 by a certain height, the water flows into the overflow port to overflow as the floating pontoon 22 begins to float upwards and causes the sealing rubber pad 6 to be separated from the sealing surface at the top of the drainage channel 110. The overflow system of the present embodiment can be installed on the overflow pipe 40 of the drain valve 4, or can be installed separately on the bottom of the water tank 5, and the principle is the same as that of the first embodiment.
