Abstract

The utility model relates to a water-saving flushing cistern with high flush strength, which is made through changing the shape and the structure of the siphon pipe of a ZL92206346. X type water-saving flushing cistern. The top of the siphon pipe is made into sector shape, and pipe a bit below the 180 DEG turning point of the water discharging side of the siphon pipe is made very narrow. Consequently, the purposes of reducing the pressing force and increasing the flush strength are achieved.

Description

High flush strength water-saving water flushing cistern

The utility model belongs to toilet bowl flushing water tank.

The water saving wc flushing cistern of patent No. ZL92206346.X is to utilize to push that buoyancy aid makes water flooding syphon top in the case, makes syphon fill water, produces siphonage, realizes flush action.Rational in infrastructure simply not perishable, stopped a seepage, flushing ability is bigger, and can be by size just different needs change discharging quantity of water, using water wisely, but blemish in an otherwise perfect thing is: backwash rate is brought up to the drain discharge per second more than 1.6 liters the time, the syphon internal diameter must strengthen, because syphon drain-side flow velocity under action of gravity is very fast, the influent side flow velocity is slower, cause syphon to be difficult for filling water, therefore will fill water and must lean on thicker buoyancy aid that more hydraulic pressure is gone into syphon, feel effort when the child pushes buoyancy aid.

The utility model purpose is to provide a kind of can overcome water saving wc flushing cistern not enough in the above-mentioned technology, the child is operated also can feel light, and have the water saving wc flushing cistern of stronger flushing ability.

The utility model purpose is achieved in that by changing siphon arrangement, cause flat at the syphon top, make little in the syphon drain-side a little less than half-turn place lower channel, make the water yield that is pressed into than originally lacking to produce siphonage ahead of time, not increasing buoyancy aid thickness but can increase and be pressed into the siphonal water yield, thereby reach laborsaving, increase the effect of intensity of washwater.

The utility model only needs to improve a little on patent No. ZL92206346.X water saving wc flushing cistern syphon basis can realize the utility model purpose.So have structure with the same simple originally, it is equally convenient to make, but have use light laborsaving, characteristics such as backwash rate is bigger.

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

Fig. 1 is the schematic diagram 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.

The water saving wc flushing cistern of high backwash rate of the present utility model comprises casing 1, syphon 2, buoyancy aid 3, connecting rod 4, depression bar 5, action bars 6, water intaking valve 7, sleeve 8, sewer pipe 9, syphon 2 is inverted-loop tube structures, and siphonal top 21 is flats, makes little in the syphon drain-side relatively a little less than the pipeline of half-turn place lower end.The lower end of gutter 23 is connected with sewer pipe 9 again, and the syphon 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 22 tube walls, be shaped on a pore hole 24, water inlet pipe 22 outer walls kiss cover sleeve 8, on sleeve 8, be shaped on one and 24 sizable holes in pore hole 81, sleeve 8 is connected with action bars 6, by action bars 6 moving sleeves 8, make a hole 81 and pore hole 24 or coincide or stagger mutually, to realize opening the pass purpose.

The water saving wc flushing cistern of the high backwash rate that the utility model constitutes is performed such work: the first, the syphon drain-side cause a little less than the pipeline of half-turn place lower end relatively little after, water be pressed into syphon flow to big tubule joining place will occur the alluvial, produce siphonage in advance and make near the big tubule joining place water pipe take the lead in filling water, needn't be as waiting until originally that whole syphon filled water and just produce siphonage.So not only early produce better siphon effect, and produce that siphonage is required to be pressed into the siphonal water yield and can to significantly reduce, thereby reach the labor-saving effect.The second, syphon top 21 caused flat after, satisfy siphonage and require the water level rising height that floods the syphon top that raises just can be lowered greatly, thus buoyancy aid can make greatly thin, thereby reach the labor-saving effect.Simultaneously the syphon top is made flat after, as under the condition that does not increase pressing force, improve the per second drain discharge, only need under the constant situation of flat pipe cross-sectional area height, the cross-sectional area width that increases pipe can reach.
