Abstract

The utility model discloses a water-leakage protecting device, which comprises a ratchet, a pawl and a small floating bucket. The ratchet is formed on the outer wall of a floating bucket of a water inlet valve. The inner chamber of the small floating bucket is provided with a buoyancy chamber and a counterweight chamber, wherein, the bottom of the counterweight chamber is provided with weep holes. The small floating bucket is assembled on the water inlet valve through a rotating shaft. The pawl part corresponding to the ratchet is fixed on one small-floating-bucket side adjacent to the floating bucket of the water inlet valve. During a water inlet process, the small floating bucket rotates with the rotating shaft as the center under the effect of buoyancy force and then abuts on a small water tank of the water inlet valve. Meanwhile, the floating bucket rises inside the small water tank under the effect of buoyancy force and the pawl is clamped in the ratchet. During a normal water discharging process, the small floating bucket rotates downwards with the rotating shaft as the center under the effect of gravity and the pawl retreats from the ratchet. Water feeding is then started through the water inlet valve. When a closestool suffers water leakage due to the fact that a draining valve or other parts inside the closestool water tank are at fault, the pawl is constantly clamped in the ratchet and the floating bucket is prevented from falling by the cooperation between the ratchet and the pawl. No water is let in from the water inlet valve. Water resources are thus prevented from being wasted and household safety of users is guaranteed.
