Description

A device that selectively uses sewage to supply flushing toilets

technical field

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

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.

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.

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. These all have a shortcoming, exactly people can't judge whether to use waste water or running water to carry out toilet flushing according to voluntary will, but finish by fixed device.

Contents of the invention

The purpose of the present invention is to provide a device that selectively uses sewage to supply water for flushing toilets, which can be operated according to one's own wishes, whether to use waste water, whether to save, these can be judged by oneself, so that waste water can be used individually and can deepen and improve people's awareness of environmental protection.

Another object of the present invention is to provide a device that selectively uses sewage to supply water for flushing toilets, collects those wasted water, and utilizes them that will be directly used without affecting the normal use of the toilet.
