Abstract
A leak-proof toilet tank, includes a toilet tank, a water-supply valve, a float cup, a float and a sealed drain device; wherein, the float cup has a sealed bottom. When the water supply is filled to the toilet tank, the water level raises up to make the float blocking the water supply. When leaks water leakage, the float cup does not leak water because of the sealed bottom, and the water level is not changed, further maintains the float to the predetermined position. The present disclosure further provides a passway for supplying water to the float cup. Even if water leakage happens, the float can be pushed to block the water supply by filling the water in the sub-tank into the float cup or by supplying water directly by the water supply pipe, so that reaching the effect of leak-proof of the toilet tank.
Claims19
A leak-proof toilet tank, comprising:
- a toilet tank, which is a container with an upward opening, wherein, the bottom of the toilet tank is provided with a first toilet tank hole and a second toilet tank hole penetrating therethrough separately;
- a single-water-supply valve, wherein, one side of the single-water-supply valve is threaded to the first toilet tank hole, the single-water-supply valve has a through hole connecting with water source for filling water into the toilet tank, the single-water-supply valve includes a single-water-supply valve body, the single-water-supply valve body is disposed outside the single-water-supply valve, the single-water-supply valve body is a pipe, and a tube ring surface extends along the axial direction of the single-water-supply valve body;
- a float cup, which is a container with a sealed bottom and an upward opening, wherein, the float cup is accommodated in the toilet tank, the water is supplied to the toilet tank through the through hole, and the water of the toilet tank overflows the float cup when the water level of the toilet tank is excessively high;
- wherein, the float cup has a tube section, a tube hole is formed in the tube section of the float cup, and the tube hole is sleeved around a predetermined position of the tube ring surface of the single-water-supply valve body;
- a float, which is a floating object, wherein the float is accommodated in the float cup and pushed to a predetermined position by the water in the float cup to block the water supply of the water source;
- when the water level of the toilet tank is reduced due to water leakage, the water level in the float cup is not changed and the float is maintained at the predetermined position;
- and
- a sealed drain device, disposed in the toilet tank, the outer edge of the sealed drain device having a fixed portion for fixing the sealed drain device in the second toilet tank hole, a drain hole disposed on the inner edge on the sealed drain device, wherein the water is drained from the toilet tank by the drain hole;
- a siphon tube is extended on a side edge of the sealed drain device, and at least one connecting pipe from the siphon tube passes through the end of the siphon tube and is connected with the float cup, wherein, the end of the siphon tube is a sealed surface of the siphon tube;
- when the drain hole drains, the water stored in the float cup is discharged by siphon effect.

A leak-proof toilet tank, comprising:
- a toilet tank, which is a container with an upward opening, wherein, the bottom of the toilet tank is provided with a first toilet tank hole and a second toilet tank hole penetrating therethrough separately;
- a double-water-supply valve, wherein one side of the double-water-supply valve is threaded to the first toilet tank hole, the double-water-supply valve has a through hole connecting with water source for filling water into the toilet tank, the double-water-supply valve includes a double-water-supply valve body, the double-water-supply valve body is disposed outside the double-water-supply valve, the double-water-supply valve body is a pipe, and a tube ring surface extends along the axial direction of the double-water-supply valve body, and a water supply pipe connecting to water supply extends along the radial direction of the double-water-supply valve body;
- a water tube, connecting to the water supply pipe for delivering the water from the water supply pipe;
- a float cup, which is a container with a sealed bottom and an upward opening, wherein, the float cup is accommodated in the toilet tank, the float cup stores the water from the water tube, the water is supplied to the toilet tank through the through hole, and the water of the toilet tank overflows the float cup when the water level of the toilet tank is excessively high;
- when the toilet tank is unable to supply the water to the float cup due to water leakage, the float cup provides water through the water tube;
- the float cup has a tube section, and the tube section is sleeved around a predetermined position of the tube ring surface of the double-water-supply valve body;
- a float, which is a floating object, wherein the float is accommodated in the float cup and pushed to a predetermined position by the water in the float cup to block water supply of a water source;
- when the water level of the toilet tank is reduced due to water leakage, the water level in the float cup is not changed and the float is maintained at the predetermined position;
- and
- a sealed drain device, disposed in the toilet tank, the outer edge of the sealed drain device having a fixed portion for fixing the sealed drain device in the second toilet tank hole, a drain hole disposed on the inner edge on the sealed drain device, wherein the water is drained from the toilet tank by the drain hole;
- a siphon tube is extended on a side edge of the sealed drain device, and at least one connecting pipe from the siphon tube passes through the end of the siphon tube and is connected with the float cup, wherein, the end of the siphon tube is a sealed surface of the siphon tube;
- when the drain hole drains, the water stored in the float cup is discharged by siphon effect.
