Water-saving flushing tank

Abstract

The invention relates to the technical field of toilet flushing equipment, and discloses a water-saving flushing tank which comprises a water tank, a water inlet valve, a floating ball and a drain valve, a partition plate is arranged between the periphery of the drain valve and the wall of the water tank to divide an inner cavity of the water tank into a first water tank and a second water tank, and the water inlet valve and the floating ball are located in the first water tank; a one-way valve for supplementing water into the second water tank from the first water tank is arranged on the partition plate close to the bottom of the water tank; the drain valve comprises a large drainage button, a small drainage button, a large-flow drainage plug controlled by the large drainage button to drain and a small-flow drainage plug controlled by the small drainage button to drain, a through hole is formed in the large-flow drainage plug and used for the small-flow drainage plug to place so as toblock water flow or separate from the large-flow drainage plug so as to drain water flow, and the small-flow drainage plug is located on the side of the first water tank. A traditional water tank isdivided into two water storage spaces, the design of double switches and double drainage holes is adopted, only water in the first water tank can be drained during small-flow drainage, water in the two water tanks can be drained only during large-flow drainage, on-demand drainage is truly achieved, and water resources are effectively saved.

Description

technical field [0001] The invention relates to the technical field of toilet flushing equipment, in particular to a water-saving flushing tank. Background technique [0002] In today's society, it is urgent to build a conservation and environmental protection society. Environmental protection and energy conservation have become the primary direction of development. Nowadays, the toilet flushing tanks used in our daily life for sewage discharge consume a lot of domestic water, and China, as a country lacking water resources, This will be a problem that needs to be optimized urgently. [0003] The current water-saving flushing tanks mainly include three types: ordinary water-saving flushing tanks, air-pressure water-saving flushing tanks, and tankless water-saving flushing tanks, but the water-saving effect is still not ideal. The current status of traditional flushing tanks is: (1) The amount of flushing water cannot be controlled, and the size of the button has almost no d...

[0003] The current water-saving flushing tanks mainly include three types: ordinary water-saving flushing tanks, air-pressure water-saving flushing tanks, and tankless water-saving flushing tanks, but the water-saving effect is still not ideal. The current status of traditional flushing tanks is: (1) The amount of flushing water cannot be controlled, and the size of the button has almost no difference in the control of the water amount. The water storage in the water tank is emptied at one time, depending on the water storage capacity of the water storage tank; (2) Siphon or flush toilets will consume 6~ 8L water, large water consumption
