Problems solved by technology
[0002] The shortage of fresh water resources has become a global problem. How to rationally use limited fresh water resources is a matter of great concern to all countries in the world. There are two ways to rationally use water resources: increase revenue and reduce expenditure. Although countries around the world have long begun to study fresh water The "open source" is mainly seawater desalination technology, but the cost of seawater desalination is very high. Therefore, at this stage, it is particularly important to "throttle" freshwater
[0003] At present, most household flushing water is clean tap water, which not only wastes precious fresh water resources, is not conducive to "saving money"; but also increases the family's living expenses

The invention discloses a flushing water-saving device, which comprises a toilet water tank and rainwater collecting tank, wherein the rainwater collecting tank is provided with a drain gully and a water outlet; the drain gully is provided with a coarse filter screen; the water outlet is provided with a fine filter screen which is connected with a rainwater conduit; the rainwater conduit is connected with the water inlet of the toilet water tank which is also connected with a household tap water conduit; the rainwater conduit and the tap water conduit are respectively provided with a rainwater control valve and a tap water control valve; and the top of the rainwater collecting tank is provided with an overfall gap, the bottom thereof is provided with a trap valve. The flushing water-saving device adopts the rainwater stored in the rainwater collecting tank to flush the toilet, when no water exits in the rainwater collecting tank, the device can open the tap water controlling valve to flush the toilet by using tap water, so that the device has simple structure, is easy to realize, saves the tap water as much as possible, has good water-saving effect and saves the household expense.
Description
technical field [0001] The invention relates to a water-saving device, in particular to a water-saving device using rainwater to flush toilets. Background technique [0002] The shortage of fresh water resources has become a global problem. How to rationally use limited fresh water resources is a matter of great concern to all countries in the world. There are two ways to rationally use water resources: increase revenue and reduce expenditure. Although countries around the world have long begun to study fresh water The "open source" is mainly seawater desalination technology, but the cost of seawater desalination is very high. Therefore, at this stage, it is particularly important to "throttle" freshwater. [0003] At present, most household flushing water is clean tap water, which not only wastes precious fresh water resources, is not conducive to "saving expenditure"; but also increases the family's living expenses. Contents of the invention [0004] The purpose of the ...
