Abstract

The utility model relates to a water saving device for a cistern. An inverted U-shaped siphon tube which is provided with a water inlet tube and a water outlet tube is arranged in a water tank, and one side of the water outlet tube is connected with a segment of elastic hose. A small water storing chamber which is provided with a water inlet hole and a water spill hole is arranged on the top of the siphon tube, and a double-bit type air-water flow dividing valve with a float is arranged in the water spill hole. Whether the small water storage chamber has water or not is controlled by a spanner, and the spanner can also control the water discharge of the siphon tube. The utility model has the advantages of no influence on the structure of the original cistern, convenient use, easy water use and easy water saving.

Description

Water saving device for cistern

The utility model belongs to a kind of water tank water saving fixtures.

Water is indispensable material during people live.Therefore economizing on water then seems is even more important.The water tank water saving fixtures of flushing toilet bowl have multiple, and the employing two cover dewatering installations that have are controlled water yield, the water-saving valve of setting up the control displacement in water tank that has.All these can both play the effect of water saving.But the construction effort is used trouble, is not easy to promote.

The purpose of this utility model is to design a kind of water tank water saving fixtures, concerning the user, during use and conventional water tank invariably with sensation, only need draw the spanner on the lower header, i.e. available water and can reach the purpose of water saving.

The purpose of this utility model realizes by following scheme: an inverted U-shaped syphon is set in the water tank, Yi Bian be water inlet pipe, Yi Bian be outlet pipe, outlet pipe one side is connected with one section elastic hose.There is a water storage cell that has inlet opening and spillway hole on reverse U shape syphon top.This hydroecium bottom is communicated with by an aperture with the syphon top.Two formula air water flow dividers that have float are arranged in the aperture.With the being and not being of water in the spanner control water storage cell, can control the generation and the disappearance of syphon siphonage, reach the purpose of water and water saving with this.

Water tank water saving fixtures simple structure to the not influence of raw water box structure, only needs the degree of depth and time by the entry of spanner control water storage cell during use, can control siphonal water yield, thereby reach the purpose of water and water saving.

Fig. 1 is a shape schematic diagram of the present utility model;

Fig. 2 is the shape schematic diagram of inverted U-shaped syphon of the present utility model and water storage cell;

Fig. 3 is the sectional view of the utility model water storage cell.

Be described as follows below in conjunction with drawings and the specific embodiments:

In Fig. 1 and Fig. 2, inverted U-shaped syphon is fixed in the water tank 2 by hold-down nut 1.Syphon is water inlet pipe 3 on one side, Yi Bian be outlet pipe 4, is connected with one section elastic hose 5 in the outlet pipe, is bonded with a water storage cell 6 at inverted U-shaped syphon top.Have inlet opening 7 above the cell, have spillway hole 8 below, spillway hole is far smaller than the size of inlet opening.Outlet pipe one side is equipped with stay cord 9, and stay cord and water tank spanner 10 join.Interlock stay cord 9 then when pulling spanner 10, because the effect of elastic hose 5,6 of the little plugs of water storage are submerged in peak level below 11, at this moment having two phenomenons takes place: (1) siphonage makes the water in the water tank flow out through outlet pipe 4, and the inlet opening 7 of water storage cell 6 intakes with the pulse type gas exhausting water intake mode; (2) spanner 10 is unclamped after, elastic hose 5 is with inlet opening and water storage cell return to primitive age position.The siphonage of this moment determines according to having anhydrous in the cell.As long as in the water storage cell water is arranged, siphonage continues, and is anhydrous in the cell, and siphonage stops, the anhydrous discharge of outlet pipe.

In Fig. 3, water storage cell 6 is round hat, and the top has inlet opening 7, and the bottom has spillway hole 8.Be equipped with in the spillway hole 8 by float 12 and reach and the ventilation thumb pad 13 of float 12 mechanical connections and two formula air water flow dividers of the bell-shaped valve that has a very thin bleed off pipe 14 15 that is connected with thumb pad.Water in the water storage cell 6 floats the bell-shaped valve 15 that has float 12.At this moment bell-shaped valve is sealed spillway hole 8, and the water in the water storage cell can only flow into syphon along bleed off pipe 14, the influence of main managed 14 sizes of its flow velocity.Water in the water storage cell needs the regular hour by 14 times of bleed off pipe, and the length of time, also will be subjected to how much restricting of the water yield in the cell 6.Therefore control the size of the water yield in the cell 6 and the length of inlet time by control spanner 10, just can control siphonal water yield indirectly.In case and the current light in the water storage cell 6, float 12 sinks, air enters syphon in a large number from inlet opening 7, spillway hole 8, destroyed siphonal vacuum, syphon stops water outlet immediately.

Claims (4)

1, a kind of water tank water saving fixtures, it is that an inverted U-shaped syphon is set in water tank, be water inlet pipe (3) on one side, be outlet pipe (4) on one side, it is characterized in that: be connected with one section elastic hose (5) in the outlet pipe (4), inverted U-shaped syphon top is bonded with water storage cell (6), has inlet opening (7) above it, have spillway hole (8) below and communicate, two formula air water flow dividers that have float (12) are arranged in hole (8) with syphon.

2, water tank water saving fixtures according to claim 1 is characterized in that: outlet pipe (4) one sides are equipped with stay cord (9), and stay cord and water tank spanner (10) join.
