Description

Water-saving toilet cistern

The utility model relates to the flusher of a kind of lavatory urinal, particularly a kind of lavatory cistern for toilet water-saving cistern.

At present, the wc flushing cistern of urinal adopts the hydrocone type structure mostly, its water retention capacity and waterdrainage amount are quantitatively, because waterdrainage amount is non-adjustable, no matter be that flushing is defecated or urine all will bleed off a whole box water, so just cause wasting of water, if reduce waterdrainage amount when flushing urine, the saving of its water is very considerable.

The purpose of this utility model is at the problems referred to above, provides a kind of needs according to the different water supply volumes of flushing excrements, the cistern for toilet water-saving cistern that carries out the variable feedwater.

The purpose of this utility model reaches by following technical solution: improve on existing siphon water tank structure, siphon cylinder top is connected with standpipe, there is blow vent on the last top of standpipe, stretch in the siphon cylinder by blow vent with the movable pull bar that connects of lever, the lower end of pull bar is connected with pouring weight, valve block, the blanking cover and the pull bar that are positioned at the stack vent upper end are fixedly connected, and when the pouring weight on the pull bar was positioned at siphon cylinder bottom portion position, blanking cover covered blow vent; The upper end of standpipe has transverse tube to be communicated with the upper end of gutter, and the retaining fork that has been fixedly connected on the water tank is connected with on the stay cord of lever and blocks, and the bottom of blocking is a handle.During flushing urine, pulling handle, and the fixed stop fork place that will block, meanwhile, by lever pull-up pull bar, pull bar drives valve block upwards, because siphonage, water enters the siphon cylinder and is discharged by gutter from siphon cylinder bottom portion, at this moment blanking cover is by the pull bar pull-up, and the blow vent of standpipe is opened, when the water in the water tank flow to the transverse tube place of exposing, siphonage stops, and water promptly stops to flow out.When flushing is defecated, the pulling handle will be shaken hands then and block and be departed from the relieving of retaining fork, make pouring weight be positioned at the bottom of siphon cylinder, and blanking cover seals stack vent, and the water in the water tank just all flows to end by gutter.

Remarkable advantage of the present utility model is that water-saving result is good, simple in structure, easy to use, existing cisten mechanism is changed less, be convenient to the water closet that has used transform, improvement expenses is few, easy enforcement.

Below in conjunction with accompanying drawing the utility model is described in detail:

Fig. 1 is the utility model schematic diagram.

Fig. 2 is the partial schematic diagram of retaining fork.

See Fig. 1～2, the top of siphon cylinder 3 communicates with gutter 2 and standpipe 7, and the top of the top of gutter 2 and standpipe 7 is by transverse tube 4 UNICOMs, and the position of its UNICOM is lower than 1/4th to 1/2nd places of peak level.There is blow vent the upper end of standpipe 7, and pull bar 6 stretches in the siphon cylinder 3 by blow vent, and the lower end of pull bar 6 is connecting pouring weight 13 and rubber valve plate 14.Pull bar 6 is linked with rubber blanking cover 5 at the upper end position of blow vent, when pouring weight 13 falls within the bottom, guarantees that blanking cover 5 seals up blow vent; Retaining fork 10 has been fixedly connected on the top of water tank 1, pull bar 7 flexibly connects with lever 8, the stay cord 9 stage casings system that is connected with lever 8 blocks 11, the position of system is when the 11 quilt retaining forks 10 of blocking block, assurance is bound up on the blow vent that blanking cover 5 on the pull bar 6 leaves standpipe 7, and 11 the bottom of blocking is connected with handle 12.Pulling handle 12 during flushing urine, pull bar 6 drives valve block 14 and moves up, because siphonage, water in the water tank enters gutter 2 by siphon cylinder 3 bottoms and discharges, and meanwhile, 11 snaps under the notch of retaining fork 10 blocking, pull bar 6 drives blanking cover 5 and rises and rest on the blow vent open mode, when horizontal plane in the case reaches the height of transverse tube 4, enter air and lose siphonage, so draining stops.When stool flushing, behind the pulling handle 12, be about to shake hands 12 and block and 11 depart from retaining fork 10 and decontrol, pouring weight 13 on the pull bar 6 falls within the bottom, this moment, blanking cover 5 will vents seal, the water in the water tank since siphonage continuously outflow from gutter 2, till flowing to end.

Claims (2)

1, a kind of lavatory cistern for toilet water-saving cistern, form by casing, ball float, water intaking valve, syphon, gutter etc., it is characterized in that transverse tube 4 UNICOMs are arranged at gutter 2 tops and standpipe 7 tops, there is blow vent standpipe 7 upper ends, pull bar 6 blanking cover 5 that has been fixedly connected at blow vent upper end position place, the retaining fork 10 that has been fixedly connected on the casing 1 and is to block 11 on the stay cord 9 that lever 8 connects.

2, lavatory according to claim 1 cistern for toilet water-saving cistern is characterized in that: the height and position of the transverse tube 4 on UNICOM's gutter 2 tops and standpipe 7 tops, should be in water tank highest level 1/4th to 1/2nd places that face down.
