The automatic water-saving device can maximally realize waste water utilization, so as to effectively save the tap water resource and reduce water expenses. The device is beneficial to the nation and the people.

Description

Automatic water saving device

Technical field

The utility model relates to a kind of automatic water saving device that rationally utilizes domestic waste water.

Background technology

What China's urban water use problem of resource became becomes increasingly conspicuous, therefore using water wisely has become state basic policy, and family washes one's face and rinses one's mouth and all flows into sewer with the water of crossing at present, then uses tap water towards urinal, wasted water resource, how making full use of waste water conserve water resource has become the problem that country takes much count of.

Summary of the invention

In view of the deficiency that prior art exists, the utility model provides a kind of automatic water saving device that makes full use of domestic waste water.The utility model for achieving the above object, the technical scheme of being taked is: a kind of automatic water saving device, it is characterized in that: comprise wash basin, header tank, overflow pipe, the wc flushing cistern of float valve is housed, two level sensors, two electromagnetic valves, infrared sensing switch and controller, described wash basin is connected with header tank by pipeline, termination overflow pipe on the header tank, the bottom is connected with float valve by the water inlet pipe of wc flushing cistern, described pipeline one end that is connected with electromagnetic valve is connected with the water inlet pipe of wc flushing cistern, another termination water supply pipe, electromagnetic valve is fixed on the bath pipeline of wc flushing cistern, infrared sensing switch is fixed on the top of wc flushing cistern, described two level sensors be installed in respectively in the wc flushing cistern on, upper/lower positions, wherein two level sensors, two electromagnetic valves, infrared sensing switch is connected with controller respectively.

The beneficial effects of the utility model are: adopt this device, can realize water reuse to greatest extent, thereby save the tap water resource effectively, reduced the water rate spending, benifit for people and nation.

Description of drawings

Fig. 1 is a system architecture schematic diagram of the present utility model and as Figure of abstract.

The specific embodiment

As shown in Figure 1, a kind of automatic water saving device, comprise wash basin 1, header tank 2, overflow pipe 3, the wc flushing cistern 4 of float valve is housed, level sensor 5,5-1, controller 6, electromagnetic valve 7,7-1 and infrared sensing switch 8, wash basin 1 is connected with header tank 2 by pipeline, termination overflow pipe 3 on the header tank 2, the following termination sewer pipe of overflow pipe 3, in case the waste water of header tank 2 overflows after being full of, the water inlet pipe that is connected with wc flushing cistern 4 is installed on the box plate of header tank 2, its water inlet pipe is connected with float valve, pipeline one end that is connected with electromagnetic valve 7 is connected with the water inlet pipe of wc flushing cistern 4, another termination water supply pipe, electromagnetic valve 7-1 is fixed on the bath pipeline of wc flushing cistern 4, infrared sensing switch 8 is fixed on the top of wc flushing cistern 4, or on the wall of wc flushing cistern 4 tops, level sensor 5 is installed in the below in the wc flushing cistern 4, level sensor 5-1 is installed in the top in the wc flushing cistern 4, level sensor 5,5-1, electromagnetic valve 7,7-1, infrared sensing switch 8 is connected with controller 6 respectively.

The special-purpose strainer of waste water process from wash basin is discharged flows into header tank 2, flows into wc flushing cisterns 4 from header tank 2 again.The volume of header tank 2 is generally the 0.3-1.2 cubic meter, and concrete size can determine that the laying method of header tank 2 positions has two kinds according to on-the-spot water actual conditions, and the one, be placed on below the washstand of upper floor; The 2nd, be placed on the position that lower floor is higher than wc flushing cistern 4, allow the water of header tank 2 flow into wc flushing cistern 4 by natural pressure, there is peculiar smell to produce for preventing header tank 2, can establish the automatic chemical dosing device in the header tank 2.The caliber of the overflow pipe 3 of header tank 2 should be greater than the water inlet caliber, and header tank 2 can be made of plastics or stainless steel.

Operating principle: water flows into wc flushing cistern 4 from header tank 2 through float valve, and wc flushing cistern 4 reaches water level in limited time, and float valve is closed; After the people entered, infrared sensing switch 8 sent to controller 6 with the signal of sensing, and controller 6 sends instruction to going out water solenoid valve 7-1, draining valve is opened, finished once flushing, this moment, wc flushing cistern 4 interior water only spent 1/2, float valve is opened, and header tank 2 supplies water, and so goes round and begins again.Water in the header tank 2 is general flushable more than 6 times, water in header tank 2 is used up, and under the situation that the water of wc flushing cistern 4 can't in time obtain replenishing, can touch level sensor 5 when lowest water level, level sensor 5 sends signal to controller 6, and controller 6 is opened entering water electromagnetic valve 7 automatically, be converted to tap water and supply water to wc flushing cistern 4, its wc flushing cistern 4 reaches water level in limited time, and level sensor 5-1 passes to controller 6 with signal, and controller 6 cuts out water supply electromagnetic valve 7 again automatically.
