Civil water-saving system

Abstract

The invention relates to the technical field of water-saving device, in particular to a civil water-saving system. The civil water-saving system comprises a transfer water tank, a first pipeline and asecond pipeline, wherein wastewater is collected and stored in the transfer water tank; the second pipeline is vertically led out from the bottom of the transfer water tank; a water outlet is locatedat the bottom of a toilet water storage tank and opposite to a tap water inlet; a switch structure is arranged at the water outlet and comprises an annular buoyancy tank structure and a change-over switch, the inside of the buoyancy tank structure is a hollow cavity structure, an annular groove is formed in the bottom, and springs are arranged in the annular groove; the change-over switch comprises a barrel-shaped main body and a piston rod, the wall of the barrel-shaped main body is inserted into the annular groove and propped against the springs, the piston rod is inserted into a center hole of the buoyancy tank structure, the center hole is open or closed by the piston at the top of the piston rod, the bottom of the piston rod is fixedly connected with the center of the bottom of the barrel-shaped main body, and a plurality of through holes are formed in the side wall of the barrel-shaped main body. According to the technical scheme, sufficient secondary utilization of domestic wastewater can be realized, so that the utilization rate of water resources is effectively increased.

Description

technical field [0001] The invention relates to the technical field of water-saving devices, in particular to a civil water-saving system. Background technique [0002] At present, in the normal life process of residents, water is needed for eating and drinking, sanitation and other activities, and each family needs to consume a lot of water, and most of these used wastewater are directly discharged, which reduces the utilization rate of water resources. At the same time, Clean tap water requires secondary pressurized water supply, especially for high-rise buildings, which consumes a lot of energy. [0003] In view of the existence of the above-mentioned problems, the inventor actively researches and innovates in order to create a civil water-saving system to make it more practical. Contents of the invention [0004] The purpose of the present invention is to provide a civil water-saving system, which can fully recycle domestic sewage, thereby effectively improving the ut...
