Water-saving device

Abstract

The invention discloses a water-saving device which comprises a main pipeline connected with a water outlet of a wash basin and a wastewater concentration detection device used for detecting the concentration of wastewater in the main pipeline, the main pipeline is connected with a sewer through a first branch pipeline, and the main pipeline is connected with a closestool water tank through a second branch pipeline, a water outlet of the hand basin is as high as the highest water level of the closestool water tank, a water inlet of the first branch pipeline is higher than a water inlet of the second branch pipeline, an on-off control valve is arranged on the second branch pipeline, and the opposite side walls of at least part of pipe sections of the main pipeline are transparent side walls, the wastewater concentration detection device comprises a light emitting unit and a light receiving unit which are arranged on the two sides of the main pipeline, and the light receiving unit is arranged to be capable of receiving light which is emitted by the light emitting unit and penetrates through the transparent side wall. The water-saving device disclosed by the invention can detect the concentration of wastewater, classify the wastewater for use, and prevent the phenomena of scaling of a closestool water tank, pipeline blockage and the like.

Description

technical field [0001] The invention relates to a bathroom water-saving device, in particular to a water-saving device. Background technique [0002] Sanitary appliances such as washbasins and toilets (sitting toilets or squatting toilets with water storage tank flushing) have been widely used in family or public toilets, and a large amount of domestic wastewater will be produced in people's daily life. , For example, in the bathroom, washing hands, face, and clothes will produce a lot of waste water, but the waste water is rarely recycled, let alone the waste water is recycled to flush the toilet, so that the water after washing hands will flow away in vain up. my country is a country seriously short of water resources. With the growth of urban population and the sharp increase of water consumption, the recycling of water resources is particularly important. [0003] At present, there are technical solutions for reusing the waste water produced by the washbasin in the bat...

AI Technical Summary

Problems solved by technology

[0005] Due to the different cleanliness of the different wastewater discharged from the sink, for example, there will be completely unused water, clean water that does not contain hand sanitizer, laundry detergent, and dirt from washing, etc., and water that contains hand sanitizer, laundry detergent, etc. The cleanliness of the recovered water entering the toilet tank is very low. After long-term use, it is prone to fouling of the toilet tank and pipe blockage.
