CN2146520Y - Flushing cistern discharging variable quantities of water - Google Patents

Abstract

The utility model relates to a box type flushing cistern which can be used to flush the toilet with variable quantity of water. The utility model is composed of a water inlet apparatus which is composed of a water tank and small-sized floating ball valves and a water discharge apparatus which is composed of a water outlet pipe, a ball shape plug, brackets, a pull rod, and a water discharge rotary handle. A floating ring is arranged on the upper side of the ball shape plug of the ball shape plug type water discharge apparatus, and the tensioning or loosing of the floating ring is controlled by chains. When loosed, the floating ring lowers according to the discharge water level. When the water lowers to a specific level, the ball shape plug is pressed and the water discharge is stopped. Inversely, the water is entirely discharged. The utility model has the disadvantage of simple structure (flushing cistern of prior art can be reformed). The purpose of water saving can be achieved by selecting quantity of water according to stool and urine.

Description

Flushing cistern discharging variable quantities of water

The utility model relates to the sanitary apparatus that a kind of flushing lavatory that discharges water is used.

At present, a kind of by water tank, the flushing device for toilet that water feed apparatus, ball-and-spigot jettison gear constitute, because of simple in structure, can be under low hydraulic pressure, weep situation operate as normal, employing widely on the single lavatory in dwelling house is supporting.But it is to select the size of waterdrainage amount that this kind flushing device for toilet has a bigger weak point, washes the lavatory at every turn and always one case water is given out light quickly.As long as and it is just much of that in fact half chests water to be put in the flushing in the lavatory after the urine, and people's urine number of times is more than stool, and this just causes the very big waste of water.

The purpose of this utility model provides a kind of box flushing device for toilet that can select big or small water yield flushing lavatory.

The purpose of this utility model is achieved in that on the jettison gear of flushing device for toilet, and the discharge water mechanism of water level of a control is set, and reaches the purpose that flushing device for toilet has big or small waterdrainage amount.

To the ball-and-spigot jettison gear: the floating ring (ring-type ball float) of a constant weight is enclosed within on the pull bar that connects bulb stopper, is arranged between bulb stopper and the support, certain distance is arranged with bulb stopper.The upper surface of floating ring links to each other with a strip metal chain (or pull bar), the other end of metallic bond is enclosed within on the stock of a lever, quarter butt and an eccentric wheel mating reaction, eccentric wheel is enclosed within on the control crank axle that discharges water, it is handled swing handle and is located at outside the water tank, rotate swing handle, can or loosen the floating ring tension by lever and metallic bond.Like this, when loosening floating ring, when the rotation flush handle discharged water, floating ring can be depressed bulb stopper with drawdown, closes delivery port, and making discharges water stops; Otherwise floating ring is not with drawdown, and one the case water will all be given out light.

Owing to adopted such scheme, flushing device for toilet can select water yield size flushing lavatory on demand, thereby bigger water-saving result arranged, this flushing device for toilet is simple in structure simultaneously (just changes on former jettison gear slightly, can reequip original flushing device for toilet), easy to operate, reliable working performance.

Below in conjunction with accompanying drawing and embodiment, the utility model is further described.

Fig. 1 is the box flushing device for toilet structural representation of ball-and-spigot jettison gear.

Fig. 2 is a ball-and-spigot jettison gear structural representation.

In the drawings: 1, water tank 2, case lid 3, water feed apparatus 4, jettison gear 5, outlet pipe 6, bulb stopper 7, pull bar 8, adjustable pipe 9, floating ring 10, metallic bond 11, lever 12, overflow pipe 13, support 14, the rod 15 that discharges water, eccentric wheel 16, selection handle 17, flush handle.

In the embodiment shown in Figure 2, the proportion of floating ring 9 can be slightly little than water, and weight is about 120 grams, and the similar bulb stopper of external diameter can be annotated by plastics and be pressed into cavity, the water filling counterweight, and sealing makes then.Adjustable pipe 8 can change (as 40～70mm) the two length of fit by being threaded into floating ring.There is the distance about 60mm the lower end of adjustable pipe from bulb stopper 6 upper ends, discharge water so that water tank can normally be opened.Lever 11, support 13, eccentric wheel 15, selection handle 16 all can be annotated by plastics and be pressed into.Eccentric wheel and lever mated, the long end of lever should have the amount of movement of 60～80mm.

Claims (3)
