AIR-PRESSING ACCUMULATION WATER-SAVING CISTERN

The utility model relates to an air-pressing energy storage water-saving tank, comprising a water tank, a water outlet valve and a water inlet valve. The upper part and the lower part of the water outlet valve are separated by the rubber film 3 of the water outlet valve. The upper part is a sealing cavity 4. The center of a water outlet valve core 7 is provided with the pore 13 of the water outlet valve core. The outer part of the guide rod 21 of the water outlet valve is provided with the spring 9 of the water outlet valve. The air-pressing energy storage water-saving tank also comprises a controlling valve 6 which comprises a tapered controlling valve core 8 and the spring of the controlling valve. The spring of the controlling valve leads the controlling valve core 8 to separate a conduit pipe 5 and a water outlet pipe. The utility model also comprises a supplementary-air valve 17 which is used for supplementing air in the water tank. The water consumption for flushing for every time is not more than 4.8 liters. The initial velocity of water current is 2.5 times as much as a common water tank. The volume is small, the flushing effect is good, and water can be saved.
