Description

Full-automatic water-saving high- and low-level cistern

The utility model provides crouching formula, sitting posture stool to go up a kind of water saving of adapted, the device that can wash away automatically after an action of the bowels.

Along with the raising of living standards of the people and developing rapidly of production, production, living water use demand sharply increase at present, but China's water resource is abundant and distributed pole is uneven.Especially urban water use is more nervous, and lack of water is serious, has become the restraining factors of China's economic development.Using water wisely has been at present and even a major issue that needs to be resolved hurrily in the very long from now on period.And the water tank of existing use, former design just has from overflow pipe, after water is full, overflows loss automatically, it is serious to waste water, the loss resource and wash away not thorough, manually unhygienic during use, the somebody is clear-cut motionless not to wash away, odor pollution environment in the washroom, and the sound that leaks night can influence people's rest.

The purpose of this utility model provides a kind of using water wisely, automatic flushing device after an action of the bowels, solving seepy question, and improves convenience and wholesomeness when using.

The utility model is to realize like this, on the full-automatic water tank of this water saving, foot switch is arranged, foot switch links together by the steel lever of backguy of steel core spring and vacuum water tank bottom, the draining valve that also has feed water valve in vacuum water tank bottom, links together with the steel lever tail, at the vacuum water tank top automatic air ball valve is arranged, between automatic air ball valve and draining valve, be connected with anti-fistulae, spring is also arranged respectively on foot switch and feed water valve.

This high low level cistern, mainly be to utilize the vacuum water tank control water yield, use in the water tank of initial vacuum anhydrous, also vacuum not, the people stool that squats down naturally during use, also just stepping on foot switch automatically, the material mechanical energy that makes full use of the people is done merit, and foot switch moves down, the backguy of transmission mechanism steel core spring, power is reached the steel lever, and the steel lever is started working, and it presses feed water valve and supplies water, move down under the effect at the steel lever simultaneously and close draining valve, water enters vacuum water tank, and when reaching the specified water yield, the automatic air ball valve is closed under the effect that water level improves.At this moment vacuum water tank, top are realized vacuum, but water continues to the vacuum water tank input, and when the pressure in vacuum water tank equated with pressure of supply water, water was no longer imported standby.When the people walks, foot switch is upspring under the resilience of spring force, the steel lever sets back under the effect of feed water valve spring force, and feed water valve is closed under the pressure of feed water valve spring and tap water, stops to supply water, draining valve drives opening water discharge when the steel lever resets, water is discharged in the specified water yield final vacuum water tank and negative pressure occurs, needs replenish air, and automatic air ball valve at this moment is under the center of gravity suction that water is discharged, automatically open, smoothly draining and flushing.

Adopt the full-automatic high low level cistern of water saving of said structure, overcome the problem of existing use water tank, because of there being the vacuum pressure water flow velocity fast from spill and leakage water, scouring capability is strong, has improved the utilization rate of water, and water-saving result is remarkable, simple in structure, easy to use, the automaticity height; And having the people to arrive to water, the function that the people leakes water and dashes has overcome simultaneously and has manually discharged water unhygienicly when using manual water tank, has solved some people and has followed the line of least resistance, and does not wash away problem of environment pollution caused after an action of the bowels.

Below in conjunction with drawings and Examples concrete structure of the present utility model and operating principle are described.

Fig. 1 is the economize on water vertical view of full-automatic high low level cistern of the utility model.Fig. 2 is a front elevation view.Fig. 3 is a side view.Fig. 4 is the foot switch schematic diagram.Fig. 5 is the A-A cross-sectional view of Fig. 1.

As shown in drawings, on the full-automatic water tank of the water saving of the utility model, foot switch 1 is arranged, foot switch links together by the steel lever 3 of steel core spring backguy 2 with vacuum water tank 6 bottoms, the draining valve 5 that also has feed water valve 4 in vacuum water tank bottom, links together with steel lever 3 afterbodys, at the vacuum water tank top automatic air ball valve 7 is arranged, between automatic air ball valve and draining valve, be connected with anti-fistulae 8, spring 10 and spring 9 are also arranged respectively on foot switch 1 and feed water valve 4.

During use, the people steps on foot switch 1 automatically, and active force reaches on the steel lever 3 of feed water valve by steel core spring backguy 2, and the steel lever moves down compressing feed water valve 4 and supplies water, and the steel lever moves down and closes draining valve 5 simultaneously, and it is standby that water is entered in the vacuum tank.When the people walks, foot switch is under the effect of spring 10, automatically upspring, the steel lever sets back under the effect of feed water valve spring 9, feed water valve is closed under feed water valve spring force and tap water pressure and is stopped to supply water, open simultaneously the draining valve draining under the drive that the steel lever sets back, the automatic air ball valve is opened under the center of gravity suction that water is discharged automatically, and water washes away smoothly.

Claims (1)

1. The full-automatic water tank of economizing on water, it is characterized in that, on described full-automatic water tank, foot switch 1 is arranged, foot switch links together by the steel core spring backguy 2 steel lever 3 with vacuum water tank 6 bottoms, also have in the vacuum water tank bottom feed water valve 4, with the draining valve 5 that steel lever 3 afterbodys link together, at the vacuum water tank top automatic air ball valve 7 is arranged, between automatic air ball valve and draining valve, be connected with anti-fistulae 8, spring 10 and spring 9 are also arranged respectively on foot switch 1 and feed water valve 4.
