Abstract

The utility model relates to a cistern, particularly a cistern for a public toilet. The utility model is characterized in that an asymmetric turnover water bucket and a siphonage passage are arranged in the cistern. The cistern is controlled by a photoelectric mechanism. When a person enter the toilet, water is filled quantitatively. When water level rises to submerge the bottom of the water bucket, the water bucket can turnover due to the action of force moment in order to cause the water level to exceed the top point of the siphonage passage, and water in the cistern can be drained completely from a water outlet under the action of water level difference and siphonage principle. The utility model has obvious effect on saving water.

Description

Water tank

The utility model relates to feed tank, is specially adapted to the public lavatory water tank.

At present the public lavatory is in order to wash away the just water tank of groove, generally be that people spur the handle water tank and discharge water, or regularly water tank discharges water automatically.And this mode of discharging water has been wasted a large amount of water, the one, people spur handle type, for long just groove, water tank volume is bigger, needn't per person all will wash away once, and people can freely spur handle, often cause per person artificially to spur, the 2nd, if the timing water descharging type is the long-time unmanned lavatory of using, just groove needn't wash again and again, regularly discharges water and causes the waste of water.

The purpose of this utility model is to overcome the defect that above-mentioned water tank is wasted water, and a kind of tipping bucket hydrocone type cistern for toilet water-saving cistern is provided.

Scheme of the present utility model is such: the upper lateral part at water tank is provided with a quarrel asymmetric bucket up, the bottom of bucket is positioned at a side of bucket center line, the outer waist of bucket lies on the thin cross bar that is fixed on the tank wall, fix the limited block of a restriction bucket corner in the water tank, the opposite side of water tank is provided with " U " shape siphon, horizontal plane when the peak of siphon is lower than the bucket upset, siphon one port leads to just groove at the bottom of being lower than water tank, the another port is positioned at water tank, at the bottom of water tank.

It is simple and ingenious that advantage of the present utility model is that structure is provided with, and plays water saving effect effectively.

Accompanying drawing is cisten mechanism figure.

1 is bucket among the figure, and 2 is casing, and 3 is thin cross bar, and 4 is limited block, and 5 is siphon, and 6 is the dewatering outlet.

The utility model is to implement like this: the right upper portion at water tank is provided with a quarrel asymmetric bucket up, the bottom of bucket is positioned at bucket center line one side, the outer waist of bucket lies on the thin cross bar that is fixed on the tank wall, bucket can rotate an angle on thin cross bar, spacing by tank wall and limited block.And the capacity setting of bucket is such: when bucket bottom timely by the water logging in the case, bucket top capacity is the line of demarcation with the perpendicular bisector at thin cross bar place, the moment that the top capacity water of this side of bucket bottom is produced is less than the moment of opposite side, to guarantee when the bucket bottom is submerged, bucket top moment difference can only be rotated to a side water in the bucket is emitted.

Left side at water tank is welded into siphon with dividing plate, and the top of siphon is lower than thin cross bar, and siphon one end is lower than and leads to that just groove is for discharging water usefulness at the bottom of the water tank, and the siphon other end is positioned at water tank, at the bottom of water tank, plays the diversion effect.Hong Dao falls the horizontal plane of " U " type peak should be lower than the bucket upset time.

During use, water tank also disposes a photo-electric control mechanism, when per person goes into the lavatory, the action of photoelectricity signal once, by-pass valve control adds water toward bucket, though because bucket can overturn an angle, the water yield of this side of the end that struggles against adds that for the end of struggling against the Capacity Ratio opposite side capacity of this upper lateral part is big, bucket can only slightly be leaned on the tank wall of bucket this side of the end, can not overturn.After water overflows bucket in the bucket, overflow and flow at the bottom of the water tank.Water level rises gradually in the water tank, though this moment, water level was higher than the dewatering outlet, is lower than " U " type bend in the siphon, so the dewatering outlet can water outlet.When water level rises to the bucket bottom, the water of Jia Ruing has just destroyed the original balance of bucket again, because this moment, the bucket end, be subjected to buoyancy, buoyancy offsets with the water weight of bucket at the end, and the moment that the water capacity of bucket this upper lateral part of the end produces is less than the moment of opposite side, so under moment loading, angle of bucket upset, all pour the water in the bucket into water tank, and in bucket when upset, run into limited block, because of and don't can tumble fully, when water is poured out certain water yield in the bucket, bucket is not only owing to buoyancy and equalising torque but also destroyed, so automatically reset, water tank discharges water and finishes a flow process.

When bucket can overturn pouring, water level in the water tank is higher than the peak of siphon, and tipping bucket water causes certain impact force, this moment is under the effect of water-head, the dewatering outlet of siphon begins big yield and discharges water, when water level in the water tank is lower than falling during " U " shape bend of siphon, water is under the effect of siphon principle, till the siphon road junction in water level is lower than water tank of still continuing to discharge water.If there is not bucket to turn over the impact force of water, when water level was higher than the siphon peak, water can only can not cause siphon slowly from the delivery port spilling water.

The action and rear water box goes round and begins again.Certainly, photo-electric control mechanism can the multiple plan of establishment, can be on time, also can by person-time, also can both furthermore.
