The toilet water tank drainage device

The utility model relates to a kind of water saving fixtures that use on toilet tank, specifically a kind of toilet water tank drainage device.

We know, in a large amount of living water uses, dash just that water occupies sizable ratio, and water supply volume is very big.The shortage of current water resource is paid close attention to by common people, how using water wisely, and still not individual economic problems, and be social concern.At present, toilet tank be mostly by casing and advance, dewatering installation constitutes, dewatering installation has piston type, valve float-ball type, float-type etc., but all be after once being fixed up, the size of displacement can not be regulated, the toilet-flushing water consumption of excrements as many, the phenomenon of wasting water is fairly obvious, adapts to water-saving requirement far from.

The purpose of this utility model is exactly in order to overcome above-mentioned the deficiencies in the prior art, provides a kind of simple in structure, installation, easy to use, and displacement is changeable, is suitable for the toilet water tank drainage device of different needs.

For achieving the above object, a kind of toilet water tank drainage device of the utility model, it is provided with outlet pipe, overflow pipe, valve, lift chain, lifting rod, plate handle, outlet pipe is fixed on the outfall of toilet water tank by base, the valve of band cap body is positioned on the outlet pipe mouth of pipe, and hinge is on the overflow pipe tube wall, it is characterized in that the plate handle includes big flood template handle and little water yield plate handle, respectively by lifting rod with lift chain and link to each other with the bonnet body, be respectively equipped with big yield and little water yield control bracket on the outlet pipe tube wall and the ball float of limiting the quantity of.

The utility model is provided with large and small water yield drain control unit, can realize district drainage, and the little water yield also can be regulated.It is simple in structure, installation, easy to use, and displacement is changeable, can satisfy the different requirements of excrements flushing supply, using water wisely.The flushing tank that the utility model can be widely used in washrooms such as public lavatory, hotel, family uses.

The utility model will be further described below in conjunction with accompanying drawing:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a kind of user mode figure of the present utility model.

As can be seen from Figure 1, a kind of toilet water tank drainage device of the utility model, it is provided with outlet pipe 1, overflow pipe 2, valve 3, lifts chain 4, lifting rod 5, plate handle etc.Outlet pipe 1 is fixed on by base 6 on the outfall of toilet water tank 7 lower curtates, and valve 3 is positioned on outlet pipe 1 mouth of pipe, and one end hinge can seal outlet pipe on overflow pipe 2 tube walls.Valve 3 tops have cap body 8, and the cap body is provided with the chain hole, are used for and lift chain and link to each other.Overflow pipe 2 lower ends are connected with outlet pipe 1, and the upper end is provided with water inlet, and from then on the water that overflows in the water tank can discharge.Above-mentioned composition and annexation and prior art are basic identical, are not describing in detail.

Characteristics of the present utility model are: the plate handle includes big flood template handle 9 and little water yield plate handle 10, and they can be located at the water tank sidewall outside, also can be located in the water tank, by the knob control operation on the tank lid.Big flood template handle 9 and little water yield plate handle 10 respectively by lifting rod 5 with lift chain 4 and link to each other with bonnet body 8, be used to mention valve, carry out draining.On the utility model outlet pipe tube wall respectively hinge big yield control bracket 11 and little water yield control bracket 13 are arranged, be respectively equipped with the ball float 12,14 of limiting the quantity of on the control bracket 11,13.Also be provided with screw rod on the little water yield control bracket 13, the ball float 14 of limiting the quantity of is provided with screwed hole, and the ball float 14 of limiting the quantity of can be along the screw rod up-down adjustment.They are according to the height of water level closing of by-pass valve control respectively.

The utility model course of work is such: when the needs big yield is flushed the toilet, press big flood template handle 9, mention valve, the cap body 8 on the valve is supported by the fulcrum of big yield control bracket 11, and valve is in open mode, carries out the big yield draining.When water is discharged to certain position, the ball float 12 of limiting the quantity of falls, and drives the big yield control bracket and swings to the right, and valve 3 falls, and seals water tank outlet, finishes the big yield drainage procedure.When the little water yield of needs is flushed the toilet, press little water yield plate handle 10, mention valve, the cap body 8 on the valve is supported by the fulcrum of little water yield control bracket 13, and valve is in open mode, carries out little water yield draining, as shown in Figure 2.When water is discharged to certain position, the ball float 14 of limiting the quantity of falls, and drives little water yield control bracket and swings to the right, and valve 3 falls, and seals water tank outlet, finishes little water yield drainage procedure.

The utility model can be realized district drainage, and is easy for operation, and displacement is changeable, can satisfy the different requirements of excrements flushing supply, is a kind of desirable toilet water tank drainage device.
