Abstract

The utility model provides a stepless controlling water discharge device for water tanks of toilets, whose major technique is that a funnel is cast on the top of a siphon tube and is communicated with the siphon tube, and a ball valve which is connected through a lever is enclosed into the neck part of the funnel. The water discharge of the water tank utilizes the siphoning phenomenon, and when the urinal is flushed cleanly, the ball valve is lifted, and air enters into the siphon tube to stop the siphoning phenomenon, achieving the purpose of the control of the water quantity. The utility model is applicable to toilets of families, hotels, etc and can save a large amount of tap water.

Description

Stepless controlling discharge part of cistern

The utility model relates to water closet.

Existing water closet, no matter how many dirts has in the urinal, an all handy whole box water washes, this wastes very much.Chinese patent CN86203611U provides " two water level urinal wc flushing cisterns ", and whole box water is divided into two-stage control displacement, and the dirt in the urinal is used half chests water after a little while; Otherwise use whole box water, reached the purpose of water saving.But the unreasonable part of two-stage control streamflow is: still waste the water yield about 1/4 the case when 1/4 case water of needs or 3/4 case water." the hydrocone type sanitary equipment of water amount controllable " that Chinese patent CN87200175U provides change displacement into stepless control, and obvious this design more becomes reasonable than the sort of design.But its problem is: when the needs whole box water washed, the people must catch hold of the water tank handle always, till whole box water has been put, did not meet the just intact custom of leaving urinal as early as possible of people.And this project organization more complicated, cost is higher, maintenance difficult.

The purpose of this utility model is to provide a kind of stepless control water closet dewatering installation.

The purpose of this utility model is achieved in that at siphonal top, casts the funnel of a cone shape, and its neck is communicated with syphon, there is a ball valve to enclose the neck of funnel, ball valve is connected with lever, and water tank has utilized the siphonage continuous drainage, washes down in urinal, in the time of need stopping draining, by lever, ball valve is lifted, charge into air in the syphon, destroyed siphonage, draining stops automatically.

Provide two embodiment below in conjunction with accompanying drawing.

Fig. 1 is the theory structure schematic diagram of the two handle types of the utility model.

Fig. 2 is the theory structure schematic diagram of the utility model list handle type.

Embodiment 1: referring to Fig. 1, at the top of syphon 6, cast the funnel 4 of a cone shape, its neck is communicated with syphon 6, has a ball valve 5 to enclose the neck of funnel 4, and the other end of ball valve 5 is connected with the handle 8 of cutting off the water by the lever 2 of cutting off the water.During dirt in needing flushing toilet bowl, the leaving behind handle 7(that discharges water should be coated with green), piston 3 lifts, and siphonage begins, cistern water-discharging.Water in water tank has not also been put, when having washed down in the urinal, and the suitable coating Red of handle 8(of cutting off the water of leaving behind), ball valve 5 lifts, and enters air in the syphon, and siphonage stops, and draining is interrupted.The 1st, lever discharges water

Embodiment 2: referring to Fig. 2, there is hole, a garden in the outside of lever 9, and ball valve connecting rod 12 is enclosed within the hole, garden of lever 9, and a horizontal plate washer 11 is arranged at the top of ball valve connecting rod 12, and piston 14 is connected with the inboard of lever 9 by spring 10.When leaving behind handle 15 the time, piston 14 lifts, and siphonage begins, cistern water-discharging, water in water tank has not also been put, when having washed down in the urinal, and the handle 15 of leaving behind again, spring 10 distortion, horizontal plate washer 11 places of ball valve connecting rod 12 have been lifted in lever 9 outsides, take up ball valve 12, and air enters syphon, siphonage stops, and draining is interrupted.
