Abstract

The utility model relates to a water-saving flushing cistern. The highest place of a siphon pipe of the utility model is a little higher than a normal water level of the cistern, when a float in the cistern is pressed, the top of the siphon pipe is immersed by the water level, thus the flushing action is realized. Simultaneously, a pipe hole which is drilled at the middle position of the pipe wall of the water intake pipe of the siphon pipe is utilized, the varieties of quantity of water flushing are realized by the opening and closing of the pipe hole, thus the purpose of water saving is achieved. The utility model has the advantages of simple structure, convenient manufacture, low cost, obvious water saving effect, and convenient operation. The water-saving flushing cistern can be made by the improvement of an existing cistern which has a siphon pipe structure.

Description

Water-saving flushing cistern

The utility model belongs to toilet bowl flushing water tank.

Mostly more advanced toilet bowl flushing water tank form of structure is to utilize buoyancy aid to move up and down to control water intaking valve work in the prior art; Utilize the piston in the syphon to move upward, cause siphonage to produce, the water in the water tank rises to siphonal outlet pipe along siphonal water inlet pipe and goes out and wash away the closet dirt.This type wc flushing cistern is rational in infrastructure simple, and flushing ability is big, receives praises from customers.But blemish in an otherwise perfect thing is: the one, and this water tank is in order to realize siphonage and to have the enough big water yield to wash the closet dirt, the siphonal water inlet pipe that piston is installed is bigger than outlet pipe, causes the siphon arrangement more complicated; The 2nd, this water tank all is disposable towards complete water volume in water tank no matter defecate or urinate when realizing flushing, and the utmost point is wasted water.

The utility model purpose is to provide a kind of can overcome water saving wc flushing cistern not enough in the prior art.It is simple in structure, can be by size just different needs change discharging quantity of water, or towards complete water tank or dash half water tank, can reach hygienic requirements again.

The utility model purpose is achieved in that the syphon highest point of setting a little more than ordinary water level in the case, can not overflow with water to be as the criterion from syphon.Buoyancy aid in the case is pushed in utilization, can make the water flooding syphon, produces siphonage, realizes flush action; The 2nd, be drilled with a pore hole in the tube wall centre position of siphonal water inlet pipe, by the sealing and the unlatching of this hole, realize the variation of discharging quantity of water, reach the water saving purpose.

The utility model only need improve on the existing water tank that is provided with siphon arrangement a little can realize the utility model purpose, so it is simple especially to have structure, and characteristics such as it is convenient especially to make, with low cost.Simultaneously, owing to can arbitrarily control discharging quantity of water, so also have water saving obviously, characteristics such as easy to use.

The utility model concrete structure is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the sectional drawing of the utility model structure.

Describe in detail according to concrete structure and the working condition that the utility model proposes below in conjunction with Fig. 1.

Water saving wc flushing cistern of the present utility model comprises casing 1, syphon 2, buoyancy aid 3, connecting rod 4, depression bar 5, knob 6, swingle 7, round buss 8, water intaking valve 9, the following mouth of a river 10.Syphon 2 is inverted-loop tube structures, is contained in a side of casing 1, and its height is a little more than the ordinary water level of casing, does not overflow from syphon with water to be as the criterion.On the centre position of siphonal water inlet pipe 21 tube walls, be shaped on the pore hole 22 that a bore is about 6mm, water inlet pipe 21 outer walls kiss cover round buss 8, on the horizon position in the pore hole 22 that is equivalent to water inlet pipe on the round buss 8, also be shaped on one and 22 sizable holes in pore hole 81, round buss 8 is connected with knob 6 on being located at casing 1 cover by the harpoon shape swingle 7 that is connected with round buss 8, rotate by knob 6 and to drive the cylindrical sleeve 8 that is connected with swingle 7 and rotate, make pore hole 22 and a hole 81 or become coincidence (unlatching) or one-tenth (closing) state that staggers.Buoyancy aid 3 adopts plastic foamboard to make, and the depression bar 5 on the case lid is connected with buoyancy aid 3 by case lid, orders about buoyancy aid 3 by moving up and down of depression bar 5 and does come-up or sinking motion.Connecting rod 4 one ends are connected with the water intaking valve 9 of water tank, and the other end is erected on the buoyancy aid 3, and by moving up and down of buoyancy aid 3, drivening rod 4 action makes the water intaking valve 9 that is attached thereto do the action that opens or closes, that is: intake or stop to supply water.

The water saving wc flushing cistern that the utility model constitutes is performed such work: water tank installs the highest point of the water level of water a little less than syphon 2 at ordinary times, when need are defecated with whole water tank water flushing, as long as depress depression bar 5, buoyancy aid 3 is sunk, cause the interior water level of case to rise and flood the top of syphon 2, siphonage produces, and water flows into the mouth of a river 10 down along syphon in the case, washes away the closet dirt.After draining finishes, siphonage stops, at this moment the connecting rod 4 that is erected on the buoyancy aid 3 falls because of own wt, water intaking valve 9 is opened, and water tank begins water inlet, buoyancy aid 3 thereby come-up, when cistern water level reaches at ordinary times the precalculated position, the connecting rod 4 of frame on buoyancy aid 3 relies on buoyancy aid 3 uplift pressure, and water intaking valve 9 is closed, and stops to supply water.When water tank water is used for flushing urine, when earlier knob 6 being rotated to an angle, the tube hole 81 that kiss is enclosed within on the outer round buss 8 of syphon water inlet pipe 21 walls overlaps with pore hole 22 on water inlet pipe 21 tube walls, depression bar 5 is depressed again, just only wash out half water tank water, reach water-saving purpose.
