Water-saving device for toilet urinal

Abstract

The invention relates to a water-saving device for a toilet urinal. At present, the water-saving effect of many water-saving toilets on the market is very limited, and a large amount of water in handwashing sinks of the toilets is completely drained into sewers and wasted. The device comprises a water storage part, a water pumping part and a flushing part; one end of a water storage tank is connected to a hand wash sink, and one end is connected to a water pumping apparatus, a pressure switch is arranged at the bottom of the water storage tank, a water inlet pipe is mounted on a side, a piston is arranged in the water pumping apparatus, a movable valve is arranged in the middle of the piston, the piston of the water pumping apparatus is connected to a first connecting rod through a straight bar, a fixed pulley fixed on the wall is connected to the piston through one end of the straight bar, and the other end is connected to a pedal, and a water outlet pipeline is disposed on a side ofthe water pumping apparatus, and a float valve is mounted at a water outlet of the water outlet pipeline. According to the water-saving device, waste water generated by the hand washing sink is collected and stored in the water storage tank, and when a person uses the urinal, the waste water in the water storage tank is pumped into a flushing tank through the water pumping apparatus to flush thetoilet, so that the purpose of saving water is achieved.

Description

technical field [0001] The invention relates to the technical field of energy saving and emission reduction, in particular to a water saving device for a toilet urinal. Background technique [0002] The problem of water resources is one of the most concerned issues in the world today. my country is one of the countries with the most water shortages in the world. The per capita water volume in my country is less than 2400m 3 , which is only 1 / 4 of the world's per capita water volume, ranking 110th in the world, and is used by Lianyuan's non-sustainable development. According to statistics, China uses more than 10 billion cubic meters of water for flushing domestic and public toilets every year, and the waste of water resources is very serious. [0003] Many water-saving toilets currently on the market achieve water-saving purposes by designing the flushing time, flushing volume, flushing pressure, and flushing effect of the flushing toilet. The water source is still natural ...

Problems solved by technology

[0003] Many water-saving toilets currently on the market achieve water-saving purposes by designing the flushing time, flushing volume, flushing pressure, and flushing effect of the flushing toilet. The water source is still natural water, and the water-saving effect is very limited. And the large amount of water in the toilet sink is all discharged into the sewer, wasting in vain
