Description

Self-flowing sanitary cistern

The utility model relates to a kind of sanitary water fitting, is a kind of water storage control appliance that is used for the washroom toilet stool washing.

Existing sanitary water fitting is made up of water storage tank, float-type water intaking valve, flushing valve, is installed on the wall and uses.Its water storage tank has only two holes, and one is the new running water inlet of water intaking valve, and one is the outfall of flushing valve.Have only a control water level in the water tank, promptly, all store and consume new tap water in the water tank by the water tank peak level of float-type water intaking valve control.The valve body of its float-type water intaking valve column long or its lower end is taken over longer, and the position that it is installed in the water tank is higher, and its control water level is the water tank peak level.One end of its float-type water intaking valve leverage is the water intaking valve valve rod, and the other end is a float, and fixed support is in the centre and near valve body.When bath with rear water box in drawdown, float also descends under action of gravity thereupon, by leverage the water intaking valve valve rod is moved upward simultaneously and opens valve, and new tap water is flowed in the case; Water level begins again to rise, and float also rises thereupon, and moves down by leverage drive valve rod, and when water level rose to the water tank peak level, the pressure that float buoyancy makes valve rod overcome tap water down by leverage was closed water intaking valve.The sandwich passage of the bleed off pipe at flushing valve column tube center by water tank bottom and outfall UNICOM be to closet, when water level above behind the peak level, in order to overflowing the water of water intaking valve seepage, so its cross-sectional area is little.The switching of flushing valve is to mention and open valve by the flush lever leverage, makes the water in the water tank drain into closet, and valve return under action of gravity is closed then.The major defect of existing cistern system is the new water of full consumption, and with water intaking valve control water tank peak level, its valve closed force is opposite with the tap water pressure direction, and the sealing of valve is relatively poor, often leaks; The overflow ducts of flushing valve is little, can only guarantee the overflow of water intaking valve percolating water.And the sanitary water fitting system that utilizes waste water in the patent documentation was a waste water system independently in recent years, form by water storage tank, flushing valve and overflow pipe, what have also has the waste water pressurization or promotes the mechanism of water level, its major defect is to use waste water, no waste water or waste water can't wash closet when not enough, and pressurization and hoisting mechanism are complicated, and can not deposit amenities such as toilet paper, soap.

The utility model is in order effectively to utilize washing and washes, can easily use new tap water flushing closet again when waste water to be not enough, solving problems such as water intaking valve poor sealing, make the new water of sanitary water fitting system saving, easy for operation, simple in structure, easy to manufacture.

This task realizes that by following approach the utility model is made up of three hole water storage tanks that have the waste water import, low water stage water intaking valve, big spout hole speed enclosed flushing valve and lid shape box, and its structure as shown in drawings.Water storage tank (3) is except that having common new running water inlet (17) and outfall (15), also has a waste water import (14), waste water import (14) is communicated with the outfall of lavatory basin by pipeline and strainer, washes can by lavatory basin directly gravity flow enter water storage tank (3) and with case in new tap water mix storage, be to increase the storage capacity of waste water, water storage tank (3) can also make that wideer thicker.Low water stage water intaking valve (1) is fixed on the new running water inlet (17) of water storage tank (3), and is communicated with water supply pipe, enters the new tap water water yield of water storage tank (3) with control.Low water stage water intaking valve (1) valve body and column are taken over very short, be that the height of low water stage water intaking valve (1) in water storage tank (3) is low, make its control position low, when water level reaches about 1/2nd (about 10-15 liters) of water storage tank (3) capacity, low water stage water intaking valve (1) is promptly closed, stop into Xin Shui, this water level is exactly a new water peak level (13), the needs of flushing when its storage capacity is enough to guarantee the waste water deficiency.The hollow float (7) that float-type low water stage water intaking valve (1) is closed in two densification is fixed on the end of lever (6), the other end of lever (6) is hinged by movable pin and fixed support (4), the valve rod (5) of band seal (2) is hinged by movable pin and lever (6), its hinge point is positioned between fixed support (4) and the float (7) and close fixed support (4), float can be in certain angle rotates around the pin of fixed support (4), drives valve rod (5) simultaneously and moves up and down and close or Open valve.Big spout hole speed enclosed flushing valve (11) is fixed on the outfall (15) of water storage tank (3), and by bath pipeline and closet UNICOM, its valve rod (10) end down has cone seal body (16), an end up links to each other with flush lever (8) leverage that is fixed on water storage tank (3) antetheca top by rope or iron wire, can move up and down with flush lever (8) and open or close flushing valve (11).Valve rod (10) center of flushing valve (11) also is a bleed off pipe, and its passage smallest cross-section area is more than or equal to the passage smallest cross-section area of the waste water of lavatory basin discharge.Under flushing valve (11) closed condition, valve rod that is to wash stream pipe (10) upper end open height at the end to the water storage tank be exactly water tank peak level (9), the water that surpasses this water level will overflow water storage tank (3) and flow into closet by the opening of bleed off pipe (10) upper end and the passage at center, and anti-sealing is overflowed by the top of water storage tank (3).Bleed off pipe valve rod (10) is limited by the upper body of flushing valve (11) with the height that flush lever (8) rises, and has limited the aperture of valve and the return distance of valve rod (10) simultaneously, so that returning quickly is closed.Lid shape box is separated out some little lattice in order to place amenities such as toilet paper, soap, scrubbing brush, washing agent simultaneously as the lid of water storage tank (3), and having loam cake above the lid shape box (12) can waterproof and dustproof.

The utility model mixes two its operating principles of water level gravity flow sanitary water fitting as the new water of waste water, must guarantee the water-head of waste water gravity flow in the system during installation, should make the level height of lavatory basin outfall be higher than the peak level (9) of water storage tank (3), the last plane that the outfall (15) of water storage tank (3) is higher than a formula or squatting pan (is the about 80cm of last plane separation ground level of lavatory basin, the peak level (9) of water storage tank (3) is about 65cm apart from ground level, and the bottom discharge mouth (15) of water storage tank (3) is about 40cm apart from ground level).In the use, when the water level in the water storage tank (3) is lower than new water peak level (13), the float (7) of low water stage water intaking valve (1) under the self gravitation effect with drawdown, and drive valve rod (5) by lever (6) and move down and make valve opening, new water from water supply pipe flows into water storage tank (3) by water intaking valve (1), at this moment also can enter water storage tank (3) by waste water import (14) simultaneously if any waste water such as wash one's hands, water level begins to increase in the water tank, float (7) rises thereupon and drives valve rod (5) by lever (6) and rises gradually, seal (2) until valve rod (5) lower end contacts with sealing surface on the valve body, low water stage water intaking valve (1) is closed, new tap water stops to enter water storage tank (3), the water level of this moment is exactly a new water peak level (13), about 10 to 15 liters of its water yield, can satisfy the needs of once flushing, when waste water is not enough, still can guarantee normal bath use; Low water stage water intaking valve (1) is when closing, its valve is two power--keep sealing under the acting in conjunction of the tap water pressure that is directed upwardly that float (7) buoyancy of leverage transmission and amplification and seal (2) back side are suffered, prevent seepage, when waste water constantly flows into water storage tank (3), water level will rise gradually in the case, when water level meets and exceeds water tank peak level (9), unnecessary water will enter closet smoothly by bleed off pipe (10), in time dredged the waste water that lavatory basin is constantly discharged, at this moment the water yield between water tank peak level (9) and the new water peak level (13) is more than 10 to 15 liters, at least (the water tank volume is big more to satisfy the requirement of a subnormal flushing, the waste water of storing is many more, just can guarantee to wash several times use) more, flushing institute water requirement is controlled by flush lever (8), when pressing flush lever (8), its leverage drive flushing valve valve rod (10) moves up and makes valve opening, water in the water storage tank (3) flows out by outfall (15) and the flushing closet, after stopping to push flush lever (8), flushing valve valve rod (10) and seal (16) are closed drainage channel at whereabouts return rapidly under the self gravitation effect and under the drive of current; After the bath, if the water level in the water storage tank (3) still is higher than new water peak level (13), then low water stage water intaking valve (1) still is in closed condition, does not replenish new tap water, be that current flushing has only consumed the mixing water with part waste water equivalent, being equal to nothing consumes new tap water; If the water level of bath back water storage tank (3) is lower than new water peak level (13), then equal current flushing and consumed water level at that time to this part new tap water between the new water peak level (13), new tap water will be opened and be replenished to low water stage water intaking valve (1) as previously mentioned, water level in water storage tank (3) reaches new water peak level (13) then closes, and stops to enter Xin Shui; If have waste water to continue to flow in the water storage tank (3) again, water level can raise again gradually, begins again after reaching water tank peak level (9) by bleed off pipe (10) overflow.

Be that advantage of the present utility model and effect are to have realized in the water storage tank that new tap water mixes storage and uses with waste water, and control its peak level respectively, waste water flows automatically fully and need not pressurize and promote the mechanism of water level, need push during except that the flushing closet the flush lever control bath water yield, all the other processes are controlled automatically; Can not consume or consume less new water, waste water is not enough or still can guarantee that normal flushing uses when not having waste water, has improved the sealing of new water water intaking valve, also can deposit amenities.
