Abstract

A siphon tube of existing hypognathous type water bucket siphon cistern is added with a vent joint, a vent pipe and a control system, which can realize the purpose of adjustable flushing water quantity. A telescopic sealed corrugated pipe is arranged between a draw rod and a water bucket interface to prevent the phenomenon of air leakage by loose fit and to ensure siphonage without mistake. The utility model has the advantages of labor saving operation and large flushing rate. Users with the cisterns can achieve the purpose of water saving by little money, and the utility model provides possibility for existing manufacturers with less investment and fast effects.

Description

The hypognathous type bucket syphon lavatory pan cistern for toilet water-saving cistern that discharging quantity of water is adjustable

The utility model belongs to sanitaryware

Lavatory pan cistern fittings pattern is various.Pull-type and turnover plate type cistern fittings will be eliminated gradually because of the shortcoming of leaking is difficult to solve.The siphon water tank accessory has watertight advantage, but except by several hydrocone type cistern for toilet water-saving cistern of applicant invention [(1) but the hydrocone type lavatory pan cistern for toilet water-saving cistern (ZL92202490.1) of discharging quantity of water regulated at will; (2) but the bushing type siphon lavatory pan cistern for toilet water-saving cistern (ZL9420767.9) of discharging quantity of water regulated at will; (3) but the scalable syphon lavatory pan cistern for toilet water-saving cistern (ZL94215444.4) of discharging quantity of water regulated at will] outside, remaining discharging quantity of water is all non-adjustable, once all consumes 9 kg of water no matter stool urine is whenever dashed.Facts have proved: the each 2-3 kg of water that only needs of flushing urine just can satisfy health demand.Discharging quantity of water is non-adjustable, has not only wasted precious water resource, but also increases the municipal sewage treatment burden.

Existing for many years in view of hypognathous type bucket syphon cistern fittings in China's producing and selling, the social owning amount of considerable scale is arranged.There is ready-made worker's die clamper in some manufacturers, have abundant knowhow and fixing marketing channel.The purpose of this utility model aims to provide a kind of design, make existing hypognathous type bucket syphon cistern fittings increase the adjustable function of discharging quantity of water, overcome simultaneously when starting siphon and need use shortcoming vigorously, make the huge numbers of families of this water tank of having installed and used spend a spot of money, change few parts and just can realize the purpose of economizing on water, also manufacturer selection less investment, the fast technological transformation of producing effects for this water tank of original production provides possibility.For realizing this purpose, of the present utility model being characterised in that adds an emptying joint on hypognathous type bucket syphon, one end of it and blow-down pipe links, the blow-down pipe other end is a drain, its degree of depth that is dipped in the water surface can arbitrarily be set, when the water surface in the water tank surfaced because of flushing drops to drain, because the suction siphon of air is destroyed, flushing stopped.The degree of depth of regulating drain can reach the adjustable purpose of discharging quantity of water, for overcoming the shortcoming that is easy to leak gas between lifting rod and bucket, adds the bellows of a telescopic sealing between them.

Below in conjunction with accompanying drawing utility model is further described.

Fig. 1 is a hydrocone type high level cistern schematic diagram, and Fig. 2 is a hydrocone type lower water box schematic diagram.Water supply valve is housed in water tank inside and ball float is the routine techniques of knowing, and is not drawn for all omitting among simple and clear two figure.The structure and the operating principle of these two kinds of water tanks are substantially the same, and all be fixed syphon and adopt hypognathous type bucket 12, lifting arm 11 and piston plate 13 to start siphon, size and to promote structure different just, we unite and are referred to as hypognathous type bucket syphon water tank.

Be to promote lifting rod 11 and piston plate 13 starts siphons, high level cistern realizes by lever 15, stay cord 16, the handle 17 of frame on bearing 14, and lower water box is then carried on the handle 18 and being realized by being directly installed on lifting on the lifting rod 11.

For increasing the discharging quantity of water adjustable function, the utility model is to add an emptying joint 3 on the arbitrary suitable position of the syphon of hypognathous type bucket, it and blow-down pipe 4 link, there is counterweight 6 at drain 5 places of blow-down pipe lower end, it is lived with backguy 7 suspentions, backguy 7 is fixed on the lock knob 9 through guide shaft (or pulley) 8, lock knob 9 can be in fixed strip 10 about (as Fig. 1) or about (as Fig. 2) slide and can be fixed on the position of a certain setting, drain 5 also is fixed on the corresponding degree of depth.Pulling lifting rod 11, piston plate 13 start siphon when washing, begin flushing, when the water surface drops to drain 5 gradually and surfaces in the water tank, because the suction of air destroys siphon, the flushing operation is ended, and the degree of depth of regulating drain can reach the adjustable purpose of discharging quantity of water.

When the water surface in the water tank was lower than the highest setting water surface, the water surface returned to the highest water surface of setting again in the (not shown) water tank under ball float and water supply valve acting in conjunction, has finished a flush cycle.

The siphonal lifting rod of hypognathous type bucket needs up and down in the bucket upper interface, so sealing can not be tight, otherwise can lift motionless and piston plate 13 can not automatically reset (decline), but sealing tightly can not leaked gas again, can not form siphon when serious and can't wash and must fast use vigorously when pulling at least and shortcoming such as bath speed is not fast.For the requirement that can satisfy these two kinds of mutual contradictions had simultaneously promptly not only sealed but also pine is joined.The utility model adds the bellows 19 of a telescopic sealing between the interface of bucket and lifting rod.To guarantee lifting rod and interface had both sealed and can be freely up and down.

Claims

1, the adjustable hypognathous type bucket syphon lavatory pan cistern for toilet water-saving cistern of a kind of discharging quantity of water, formed by water supply valve, ball float, hypognathous type bucket syphon, piston plate and shift mechanism, it is characterized in that adding on the syphon emptying joint, it and blow-down pipe link, the other end of blow-down pipe is that the degree of depth that drain is dipped in the water surface can be set arbitrarily, when the water surface in the water tank surfaces because of flushing drops to drain, because the suction siphon of air is destroyed, flushing is ended, and the degree of depth of regulating drain can reach the adjustable purpose of discharging quantity of water.

2, the adjustable hypognathous type bucket syphon lavatory pan cistern for toilet water-saving cistern of a kind of discharging quantity of water as claimed in claim 1 is characterized in that adding between the interface of lifting rod and bucket the bellows of a telescopic sealing.
