CN2168892Y - Dual dosing toilet bowl with syphon and air-tight sealing - Google Patents

Abstract

The utility model relates to a water-saving toilet bowl which overcomes the defects that a traditional siphon type toilet bowl has easy leakage, single quantity of water flushing and high failure rate. Airtight leakproof method is adopted, so the utility model has no water leakage phenomenon, low failure rate and two quantity of water flushing, and can be used on both high and lower level toilet bowls. The utility model comprises two M-shaped siphon tubes, two U-shaped tubes, two hoses, two right-angle bent tubes and an overflow tube. The tube mouth on one end of each U-shaped tube is respectively connected with a hose, and the other end of each hose is connected with a bent tube. The other ends of the bent tubes are respectively inserted into two circular holes on the siphon tubes which are communicated with the bent tubes. The tube mouth lower end of the overflow tube is communicated with the water outlets of the two siphon tubes, and the pipe mouth of the upper end of the overflow tube is communicated with atmosphere. The water level of the water inlets of the two siphon tubes are different.

Description

Dual dosing toilet bowl with syphon and air-tight sealing

The utility model belongs to a kind of flushing device for toilet that is used for the lavatory.

At present, the traditional hydrocone type flushing device for toilet that is used for family and public lavatory, the overwhelming majority all exists and have more than is neededly how long just may seep water, leak and defective that discharging quantity of water is single, and the basic reason of seepage to be the movable sealing part of the employed cock of water drain of these syringes system all belong to the mechanicalness sealing, in use, because constantly movable and wear and tear easily and be out of order and cause infiltration, leak, it is single to add discharging quantity of water, has caused great waste.Chinese patent application 88219786.X and 91210680.8 disclosed hydrocone type flushing device for toilet though proposed to solve the single technical scheme of discharging quantity of water, have all still adopted traditional mechanicalness antiseep sealing means, therefore, its antiseepage, leakage poor reliability, fault rate height, and operation inconvenience.

The purpose of this utility model is that design is a kind of simple in structure, and no movable sealing part does not seep water, leaks, but excrements wash respectively, fault rate is low, the siphon airproof that high low level all can use pair water yield water-saving flushing toilet stools.

The utility model realizes that the technical scheme that above-mentioned purpose adopts is: utilize two M type syphons, two U type pipes, two flexible pipes, two right-angle elbow pipes and a bleed off pipe, U type pipe two mouths of pipe connect flexible pipe respectively, the flexible pipe other end connects right-angle elbow pipe respectively, the bend pipe other end inserts two circular holes that communicate with it on the syphon respectively, the bleed off pipe lower end mouth of pipe communicates with two siphonal delivery ports, the upper end mouth of pipe communicates two siphonal water inlet height of water level differences with atmosphere.Before the use, the vent plug that respectively has one section cavity to form in syphon, the U type pipe, pipe internal pressure balance, system is in static state.During use, the pulling handle, U type pipe is pulled up, and causes inner pipe water pressure and reduces, and under the effect of vent plug pressure, water is extruded in the pipe, forms blank pipe, and air promptly is discharged from thus in syphon and the U type pipe cavity, and vent plug disappears, the flushing beginning.Siphon power disappears in the flushing final stage system, and the water in syphon and the U type pipe is back to the stage casing, and air flows to gutter to the water in the pipe through bleed off pipe and arranged, and flushing finishes.Again water filling because the stage casing water is arranged, causes vent plug and forms again.

This reality is compared with prior art novel, the advantage that has is: overcome existing traditional hydrocone type flushing device for toilet easy to leak, fault rate height, the defective that discharging quantity of water is single, it is simple in structure, owing to adopted airtight leak-proof manner, so no movable sealing part is the problem that has fundamentally solved infiltration, leaked, can large and smallly just wash respectively, high low level all can use, and long service life, and fault rate is low.

Below in conjunction with description of drawings embodiment:

Fig. 1～Fig. 4 is the sectional view under each duty of the utility model.

Fig. 1, the cavity that all has one section air to form in syphon 1.2 and the U type pipe 3.4, i.e. vent plug, it remains on due position at ordinary times, and the pipe internal pressure is in equilibrium state, has stoped flowing of water.

Fig. 2: when needing flushing, with the big yield flushing is example, pulling handle 6, U type pipe 3 is pulled up, and causes inner pipe water pressure and reduces, under the effect of vent plug pressure, water in the U type pipe 3 is extruded from circular hole 9, forms blank pipe, and the air in the cavity is discharged from circular hole 9 through U type pipe 3 by circular hole 8, vent plug disappears, the flushing beginning.

Fig. 3, the flushing later stage is because siphon power disappears in the syphon 1, current stop, and the water in syphon 1 and U type pipe 3 all is back to the stage casing, by the formed siphon power that falls under water in the gutter 12, disappear through all having arranged to the water in the pipe by the replenish air of bleed off pipe 5, flushing finishes.

Fig. 4: the water valve water filling, owing to all leave one section water in syphon 1 and the U type pipe 3, so can form vent plug again again.

In like manner, when needing the little water yield to wash, pulling handle 7, U type pipe 4 is pulled up, and the pipe internal pressure reduces, and the air in the cavity is discharged by circular hole 11 through U type pipe 4 from circular hole 10, vent plug disappears, the flushing beginning is because syphon 2 water inlet water levels are higher, so discharging quantity of water is less, the flushing later stage, siphon power disappears in the syphon 2, and current stop, and the water in syphon 2 and U type pipe 4 all is back to the stage casing.The formed siphon power that falls under water in the gutter 12, still by having arranged and disappear to Guan Zhongshui through the replenish air of bleed off pipe 5, flushing finishes, and after the water filling, forms vent plug again again in syphon 2 and U type pipe 4 again.
