CN2259440Y - Water-saving cistern for water closet - Google Patents

Abstract

The utility model relates to a water-saving cistern for a water closet. The utility model is provided with a circular cover hanger bracket which is arranged on a drain pipe, and the topmost point of the drain pipe is higher than the normal water level in the cistern. A floating body in the cistern is pressed to cause the top part of the circular cover to be flooded by the water level to form the siphon, and the flushing action can be realized. Simultaneously, the closing and the opening of the circular cover can be used for realizing the variation of the quantity of flushing water, and the purpose of water saving is achieved. Besides, a piston of a water inlet valve and the floating body are formed into a whole, which ensures the sensitivity of the opening and the closing of the water inlet valve. The utility model has the advantages of simple structure, easy fabrication, obvious effect of water saving, low cost, convenient operation, etc.

Description

Economizer water tank for excrement pan

The utility model belongs to closet water saving wc flushing cistern

The water tank that present flushing closet generally uses is a plug envelope formula, and draining valve is installed in water tank bottom, places water storage, because the draining valve rubber stopper seals easy aging distortion, it is close to be difficult for the pass, and fault not in place often appears in rotating operation, thereby drainage often occurs.No matter it all is disposable towards complete water volume in water tank defecating or urinating, the utmost point is wasted water.And water intaking valve also can emit water to cause radiator leak because of fitting badly sometimes.

The purpose of this utility model is to provide a kind of water tank that can overcome novel draining water intake mechanism not enough in the above-mentioned technology, and it has water-tight, using water wisely, fragile, easy to use, not cheap toilet bowl flushing water tank.

The utility model purpose is achieved in that and adopts the circle shroud to be suspended on the gutter that water flooding circle shroud upper end formed siphon and washes when buoyancy aid pressed down, and placed water storage to be difficult for closing close and drainage thereby thoroughly overcome plug envelope formula draining valve.Pass through the sealing and the unlatching of circle shroud hole simultaneously, the realization discharging quantity of water changes, using water wisely, and adopt and to press down the structure that buoyancy aid and water intaking valve piston rod are formed integral body, draining rapidly can promptly be intake having arranged water again, buoyancy aid rises with water level and constantly floats, by the buoyancy aid buoyancy, water intaking valve is fastened, overcome traditional water intaking valve preventing water phenomenon sometimes.

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

Fig. 1 is the utility model structural representation.

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

Economizer water tank for excrement pan of the present utility model comprises casing 1, case lid 2, and gutter 3, circle shroud 4, suspension 5 between vestlet, round buss 6, knob 7, spear type swingle 8, button 9, buoyancy aid 10, water inlet valve port 11, water intaking valve piston rod 12, water intaking valve pipe 13, flap valve 14.Circle shroud 4 is suspended on the gutter 3, and the height on gutter 3 tops is a little more than the ordinary water level in the casing, does not overflow from gutter with water to be as the criterion.On the centre position of circle shroud 4 cover walls, be shaped on the cover hole 41 that a bore is about 6mm, circle shroud 4 outer walls kiss cover round buss 6, on the horizon position that is equivalent to circle shroud cover hole 41 on the round buss 6, also be shaped on one and 41 sizable holes of circle shroud hole 61, round buss 6 is connected with knob 7 on being located at case lid 2 by the harpoon shape swingle 8 that is connected with round buss 6, rotate by knob 7 and to drive the round buss 6 that is connected with swingle 8 and rotate, make cover hole 41 and a hole 61 or become coincidence (unlatching) or one-tenth (closing) state that staggers.Buoyancy aid 10 and button 9 water intaking valve piston rods 12 water intaking valve pipes 13 are formed whole, by moving up and down of buoyancy aid 10, drive piston rod 12 and move up and down, and make water valve port 11 into do the action that opens or closes, that is: intake or stop to supply water.The capping of case lid 2 above circle shroud 4 one sides causes female cap 21, and female cap 21 works the piece effect of restricting water supply in casing 1, can be used as the usefulness of putting toilet paper or spices deodorant on the spill case lid.

The economizer water tank for excrement pan that the utility model constitutes is performed such work: water tank installs the water level of water a little less than gutter 3 highest points at ordinary times, when need are defecated with whole water tank water flushing, as long as press push button 9 (high level cistern to pan then pulls handle), buoyancy aid 10 is floated downward, cause the interior water level of case to rise and flood the top of round shroud 4, the gutter 3 that forms in the circle shroud 4 produces siphonage, and water flows out flushing closet dirt from the draining mouth of pipe.After draining finished, siphonage stopped, and at this moment kickboard 10 and piston rod 12 fall because of own wt, water valve port 11 is opened, water tank begins water inlet, and buoyancy aid 10 thereby come-up are when cistern water level reaches precalculated position at ordinary times, buoyancy aid 10 relies on uplift pressure, to pull on the piston rod 12 that buoyancy aid 10 links together, water inlet valve port 11 will be closed, and stop to supply water, water level returns to the preceding height of draining in the case, for draining is next time got ready.When water tank water is used for flushing urine, earlier knob 7 is rotated to an angle, the tube hole of kissing on the round buss 6 that is enclosed within round shroud 4 outer walls 61 is overlapped with the cover hole 41 that circle shroud 4 covers on the walls, again button 9 is depressed, just only wash out half chests water, reach the purpose of water saving.
