2. the each bath water supply volume that has closet now is according to the design of stool bath consumption, and the discharging quantity of water of in fact urinating can be less than the consumption of washing by water less than stool.And the bath consumption of at present domestic and international all closets all is identical, and the water supply volume of urinating normal person's every day is more than 10 times of water of stool, so exist very considerable water wasting phenomenon.

3. outside the waste problem that dewaters, it is little convenient that existing closet also exists operation, firmly bigger during use, is not suitable for problems such as the elderly and children.

The utility model is intended to solve the scarce limit of above prior art, and a kind of electric liquid closet water-saving control device is provided.Adopted advanced mechanical, electrical, liquid integrated transmission, control structure, made the fair supply respectively of excrements water supply volume basis needs separately.Simultaneously make rational in infrastructure, reliable operation again, improved the sealing performance of valve, make easy to operate.Can avoid again in public places contacting the problems such as disease propagation that cause because of staff.

The utility model is made up of water inlet, fluid level control valve, electro hydraulic valve, diaphragm valve, hydraulic cylinder, controlled valve and water tank.The water that enters from water inlet is opened this control valve and is entered water tank through tee junction one termination fluid level control valve.Another termination electro hydraulic valve and diaphragm valve, the water that flows out from diaphragm valve connects hydraulic cylinder, is flushing valve below the hydraulic cylinder, and the hydraulic cylinder on the flushing valve valve rod has back-moving spring.

The utility model adopts the technical scheme of mechanical-electrical-hydraulic integration, inflow with frame for movement control water tank, open and close with hydraulic drive and control technology expelling water case flushing valve, water yield with electro hydraulic on-off valve, fast-discharge valve and delay control circuit control water tank, Cistern valve and its drive unit are designed to one, reliability is closed in assurance, and electro hydraulic on-off valve and fast-discharge valve are designed to one, and electro hydraulic on-off valve and water tank water intake control valve are set as the shared water inlet of one.

Accompanying drawing 1 is the utility model structural representation.

Accompanying drawing 2 is the utility model schematic diagram.

In conjunction with the accompanying drawings 1, flushing valve 2 is designed to the cut-off type structure, adopts the end face rubber seal, is characterized in that this opening of valves stroke is short, and the time that needs is also short, thus towards the time kinetic energy big, effective, favorable sealing property.The hydraulic cylinder 3 of controlled valve 2 usefulness is designed to single-acting formula diaphragm structure, the closing of valve with spring force and gravity, and characteristics are that this cylinder is difficult for leaking, action is fast, better tightness when spring force makes valve closing.This valve and driving cylinder fuse, and have guaranteed that the position mutually of valve seat and spool can not misplace, and have improved the reliability when closing.Cylinder 3 work Open valves 2 are to rely on the pressure of tap water to finish, and supply water and draining is that pilot valve, Rolling valve are that the electro hydraulic valve 5 of main switching valve is controlled by diaphragm valve 4 with the electromagnetic valve.The advantage of designed electro hydraulic valve 5 is that the electromagnet volume of this valve of driving is little, in light weight, and power is little, and power consumption is little.The function of designed diaphragm valve 4 is; When the needs hydraulic cylinder works, after the electromagnet action, the press water from electro hydraulic valve flows out is closed the runner that valve 4 leads to water tank 1, and is entered hydraulic cylinder 3 by this valve working hole, makes cylinder 3 actions open valve 1, and water is gone out from water tank.After the electromagnet outage, electro hydraulic valve 5 is closed and is cut off the water supply, valve 4 diaphragm epicoele decompressions, the elastic force of diaphragm makes the working hole of valve 4 communicate with the passage that leads to water tank, the spring force of hydraulic cylinder 3 diaphragm epicoeles makes diaphragm drive valve rod and moves downward, and the water of cavity of resorption flows into water tank 1 through valve 4, and valve 2 cuts out simultaneously.Tank intake valve of water 6 is designed to by the control structure that combines with diaphragm, and the unlatching of valve 6 relies on hydraulic coupling, and closing is the lever force F that relies on the buoyancy conversion of liquid level rising.Characteristics are favorable sealing properties, valve open and close automatic realization.

In conjunction with the accompanying drawings 2, the operating principle of this closet water-saving control device is: when press water enters system from water inlet 7, enter water tank 1 through fluid level control valve 6, when the water yield that flows into water tank reaches the liquid level of regulation, valve 6 cuts out (liquid level can be regulated according to the bath consumption) automatically, and the water in the water tank 1 is standby.When needing bath, open electro hydraulic on-off valve 5 energising backs, the press water that water inlet 7 enters enters valve 4 through valve 5, make the pathway closure of valve 4 to water tank, the working hole of opening valve 4 simultaneously enters hydraulic cylinder 3, make diaphragm drive valve rod and move upward, valve 2 is opened, the standby water in the water tank 1 flows into the urinal bath fast through valve 2.Close during electro hydraulic valve 5 outages, press water cutout decompression, the outfall of valve 4 is opened.The spring in the hydraulic cylinder 3 and the gravity of valve member move downward the slide core of valve 2, and the water of cylinder 3 cavity of resorptions flows into water tank from valve 4 outfall.Valve 2 cuts out at the same time, because water-rinsing process makes the liquid level in the water tank that variation take place, lever force F disappears, and valve 6 is opened by press water again, and the feed tank water inlet is standby.Large and small water supply volume just is that the length by 5 conduction times of automatically controlled part control valve realizes.Valve is short 5 conduction times during the urine bath, and what the water in the water tank just flowed out lacks.The electric switch of automatically controlled part, according to easy to use be principle, be installed in the optimum position.Different designs according to the field of employment becomes various form of structure, selects for use for the user.For example in public places, can select pedal switch or non-contact switch for use, avoid the infection of the disease that causes because of hand contact, also solve at present in public places some people pollution on the environment of washing by water thus thereby not.Because effect has the spring force in the cylinder 3 on the valve 2, can make valve 2 excellent sealings, stifled leakage of having cut off valve 2 has improved and has closed reliability.Cross when hanging down phenomenon if improper power failure or hydraulic pressure occur, can open valve 2, wash by water by the annular hand grip on cylinder 3 tops.Just in case fluid level control valve breaks down, occur leaking, water in the water tank might be higher than ordinary water level, the possibility of useful water tank, for anti-sealing overflows water tank, we are designed to hollow valve rod to the valve rod of valve 1, when water level is higher than ordinary water level, the water that leaks can flow into urinal by the through hole in valve rod, avoids water to overflow from water tank.In sum, this device solves the identical and valve 2 of large and small just water supply volume close the bad water waste problem that causes, that the switch control of automatically controlled part makes is easy to operate, laborsaving, improved reliability and advance.
