Device for supplying water to flushing toilet through selective use of sewage

Abstract

The invention provides a device for supplying water to a flushing toilet through selective use of sewage. The device comprises a sewage storage tank, a toilet water storage tank, a pressurized water storage tank, a pumping device and a one-way pressure valve, wherein the sewage storage tank is provided with a first sewage inlet and a first sewage outlet; the pressurized water storage tank is higher than the sewage storage tank and the toilet water storage tank, and the pressurized water storage tank is provided with a second sewage inlet which communicates with the firs sewage outlet and a second sewage outlet which communicates with the toilet water storage tank; the pumping device is arranged between the first sewage outlet and the second sewage inlet; and the one-way pressure valve is arranged between the second sewage outlet and the toilet water storage tank. The device provided by the invention, on the basis of supplying water to the toilet by the sewage, can achieve the selectiveuse of the sewage, and the use of the sewage can be determined in the accordance with the voluntary willing of people, so that environmental awareness is enhanced, and meanwhile, the flexible and individual use of the wastewater (the sewage) is achieved.

Description

technical field [0001] The invention belongs to the field of water supply devices, in particular to a device for selectively using sewage to supply water to flush toilets. Background technique [0002] Water, as a non-renewable resource. Although 70% of the earth is covered by water, fresh water resources only account for 2.53% of it. Most of the fresh water exists in the form of glaciers, snow and permafrost, and the fresh water resources that can be used by people only account for 1.74%. So how to save water has always been a concern of people. However, my country's per capita water resources are only 2,240 cubic meters, which is far below the world's per capita water resources standards. At the same time, the mineral water economy also occupies a large part of my country's economic market, so the shortage of water resources will gradually become an obstacle to my country's economic development. How to save water has become an urgent problem at present. [0003] After...

AI Technical Summary

Problems solved by technology

[0003] After long-term observation of people's daily water habits, we found that people's domestic water is mostly produced by washing clothes, cooking, washing dishes, bathing, etc., and it is basically used for one time. After use, it is directly drained through underground pipes. Go, without any treatment and processing for the second or even third use, this way of using water is extremely wasteful, and it is also a problem that needs to be solved

At the same time, we also found that whether it is the flushing system of the domestic toilet or the toilet flushing system in public places, it basically uses relatively clean tap water for the first time, and this water can also be used in daily life. A phenomenon in which water resources are wasted

[0004] In the prior art, waste water is used to flush the toilet, and the waste water is often directly connected to the toilet storage tank for utilization. Although the use of waste water can be realized, in the actual use process, due to insufficient waste water, or the smell of waste water and residues, etc. The user does not need waste water temporarily, but it cannot be adjusted artificially; or the tap water and waste water are connected to the toilet storage tank at the same time, so that the tap water can be supplemented when the waste water is insufficient, but the tap water can only be used after the waste water is used up.

All of these have a shortcoming, that is, people cannot judge whether to use waste water or tap water to flush the toilet according to their own will, but it is done by a fixed device.
