Therefore, the Ministry of Construction issues mandatory provisions: Washing water for each flush cycle of the product The amount is not more than 6 liters. When the water pressure is 0.3Mpa, the product for stool flushing has a flushing capacity of 6-8 liters, and the flushing product has a flushing volume of 2 to 4 liters. In fact, flushing water does not require high water quality. It can be done by using existing wastewater, such as washing, washing vegetables and washing water. Since it does not contain oil impurities, it can be used directly without chemical or physical treatment. Rush. Existing systems or devices that collect domestic sewage for flushing usually collect all domestic sewage such as face washing, dish washing, and laundry, and then use physical and chemical treatment methods for treatment. This often requires the addition of power equipment, or the construction of the device to occupy a limited living space, complex structure, inconvenient to use, is not conducive to promotion in general households, hotels and public toilets. SUMMARY OF THE INVENTION The problem to be solved by the present invention is to provide a water-saving flushing system that is simple in structure, low in cost, and easy to implement in general households, households, and public toilets. To this end, the water-saving flushing system provided by the utility model comprises a domestic water tank and a flushing water tank, and a domestic sewage water tank is arranged below the living water tank, and the living water tank has two water holes, one of which passes through the water hole The pipeline is connected to the sewer port, and the pipeline is arranged in a groove on the outer side wall of the domestic sewage treatment tank, and the sewage outlet at the lower end of the domestic sewage treatment tank passes through the conveying pipe and the flushing water.

When the domestic sewage generated in the domestic water tank contains oil or other impurities that are difficult to clean, one of the drains is directly discharged into the sewer through the pipeline; if the domestic sewage generated after washing the face, washing hands or washing vegetables in the domestic sink is more When cleaning, it is temporarily stored in the domestic sewage treatment tank below the other water outlet. When the water level in the flushing tank drops and the water level of the domestic sewage in the domestic sewage treatment tank is sufficient, the domestic sewage enters the flushing water tank from the domestic sewage treatment tank through the conveying water pipe, and is used as a common water source for flushing with the tap water. Under normal circumstances, the tap water connected to the flushing water tank is normally closed. Try to use the water sent from the domestic sewage treatment tank to flush the toilet or the toilet. When the water in the domestic sewage treatment tank is not enough, the tap water switch is turned on, and the tap water is used. Rush. When space permits, a dedicated water storage tank can be added between the domestic sewage treatment tank and the flushing water tank to store and utilize domestic sewage more. Compared with the conventional flushing water tank which only uses tap water as the water source, the consumption of tap water is greatly saved, thereby achieving the purpose of saving water. The utility model has the beneficial effects that the clean domestic sewage generated by people's daily life can be stored and used as a common water source for the flushing with the tap water, and the whole system has a simple structure, and the existing living water tank and the flushing water tank are provided. The structure is not changed greatly, nor is it added to other power equipment or complex physical and chemical treatment equipment, and the cost is low, and it is easy to promote and apply in general households, hotels and public toilets.
