Abstract
The utility model discloses a water-saving flushing device which comprises a toilet water tank and a rain water collecting case. A water receiving port and a water outlet are formed on the rain water collecting case, a coarse filter screen is arranged at the water receiving port and a fine filter screen connected with a rain water guide pipe is arranged on the water outlet, the rain water guide pipe is connected with the water inlet of the toilet water tank, a household tap water guide pipe is connected with the water inlet of the toilet water tank, a rain water control valve and a tap water control valve are arranged on the rain water guide pipe and the tap water guide pipe respectively, and a overflow port is formed at the top of the rain water collecting case and a decontamination valve is arranged at the bottom of the rain water collecting case. The rain water collecting case in the provided water-saving flushing device can store rain water for flushing, and when the rain water collecting case has no rain water stored therein, the tap water control valve is opened and the tap water is used to flush, thereby achieving simple structure and easy realization. In addition, tap water is saved as far as possible, water-saving effect is good, and household expense is saved as well.
Description
Technical field
The utility model relates to a kind of water saving fixtures, particularly relates to a kind of water saving fixtures that utilize rainwater to flush the toilet.
Background technology
Freshwater resources are in short supply to have become a global problem, how rationally utilizing limited freshwater resources is problems that countries in the world are all paid special attention to, rationally use water resource that two approach are arranged: to increase income and throttling, fresh water " is increased income " though countries in the world begin one's study very early, mainly be the technology of desalinization, but technology realize that Cost of seawater desalination is very high at present, therefore, in present stage, fresh water is carried out " throttling " just seem particularly important.
At present, the flushing supply of family expenses mostly is clean tap water, has so not only wasted valuable freshwater resources greatly, is unfavorable for " throttling "; And the life that has increased family is paid wages.
The utility model content
The purpose of this utility model is to provide a kind of flushing water-saving device, and it can be collected rainwater and provide water for the lavatory, have simple in structure, the characteristics that water-saving result is good.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of flushing water-saving device, it comprises water-closet tank, described water-closet tank water inlet is connected with water supply pipe, wherein, described water-closet tank water inlet also is connected with the rainwater storage bin, and described rainwater storage bin top is provided with drain gully, and its bottom is provided with delivery port, described delivery port is connected with the water-closet tank water inlet by storm sewer, and described storm sewer is provided with the rainwater control valve, and described water supply pipe is provided with the tap water control valve.
Described rainwater storage bin top is provided with overfall gap, and described rainwater storage bin bottom is provided with trap valve.
Described rainwater storage bin drain gully is provided with the coarse filtration net, and described rainwater storage bin delivery port is provided with thin screen pack.
The beneficial effects of the utility model are that described flushing water-saving device utilizes the rainwater that stores in the rainwater collecting box to flush the toilet, and when not having water in the rainwater collecting box, can open the tap water control valve and utilize tap water to flush the toilet, and is not only simple in structure, is easy to realize; And saved tap water as much as possible, water-saving result is good, has saved family expense.
Description of drawings
With embodiment the utility model is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the structural representation of the utility model flushing water-saving device.
Among the figure:
1, rainwater collecting box; 10, drain gully; 11, coarse filtration net; 12, overfall gap; 13, overflow pipe; 14, trap valve; 15, delivery port; 16, thin screen pack; 2, water-closet tank; 20, water inlet; 3, rainwater conduit; 4, tap water conduit; 5, rainwater control valve; 6, tap water control valve.
The specific embodiment
Please refer to shown in Figure 1, Fig. 1 is the structural representation of the utility model flushing water-saving device, in present embodiment, a kind of flushing water-saving device, it comprises rainwater collecting box 1, the top of described rainwater collecting box 1 offers drain gully 10, described drain gully 10 is provided with coarse filtration net 11, big impurity in the rainwater is tentatively filtered the back to be entered in the rainwater collecting box 1 from drain gully 10, and the top of described rainwater collecting box 1 also offers overfall gap 12, when the rainwater in the rainwater collecting box 1 fills with, can flow out through overflow pipe 13 from overfall gap 12, and the bottom of described rainwater collecting box 1 is provided with trap valve 14 and delivery port 15, described trap valve 14 can regularly be opened so that the impurity that is collected in rainwater collecting box 1 bottom is removed, described delivery port 15 is provided with thin screen pack 16 and connects rainwater conduit 3, described thin screen pack 16 filters dust and other fine impurities in the rainwater, the water inlet 20 that rainwater control valve 5 connects water-closet tank 2 is set on the described rainwater conduit 3, described rainwater control valve 5 is provided with water level display (not illustrating among the figure), and described water inlet 20 also connects tap water conduit 4, and described tap water conduit 4 is provided with tap water control valve 6.
When rainy, at first rainwater collecting box 1 is filled with, rainwater enters rainwater conduit 3 through coarse filtration net 11 with after carefully screen pack 16 filters, the rainwater control valve 5 that is provided with on the rainwater conduit 3 detects by water level display at this moment has rainwater to store in the rainwater collecting box 1, open rainwater control valve 5, and close tap water control valve 6 simultaneously, the use rainwater is flushed the toilet, when no rainwater, the rainwater control valve 5 that is provided with on the rainwater conduit 3 detects no rainwater storage in the rainwater collecting box 1 by water level display, rainwater control valve 5 is closed, and opens tap water control valve 6 simultaneously, flushes the toilet with tap water.
