Dual flush device for toilet water tank

Abstract

The present invention is related to a dual flush device for toilet water tank. A manually-operated press handle, in which a first switch-bar and a second switch-bar are intercalated on, is installed on a side-wall of the water tank. The switch-bar has a hollow bed, the tube of the hollow bed has a pivotal hole of the holder. The front edge of a bent-arm conjugates with an axial hole of the second switch-bar, the other end of the bent-arm has a chain which is fixed in a central hole of a moving element of a water-drainer. The round axis of the holder conjugates with a conduct hole of a gliding plate; and the screw nut is fixed by a stud to hold a float-ball under water. The water-drainer has a draining part. Inside the draining part there is a moving element. The moving element has a central hole, and a flush valve at the bottom, and a float-ball held in inner space. Below the draining part, there is provided an outer screw-thread, on the outer screw-thread there is mounted a base. In view of the above disclosure, it is the primary intention of the invention to successfully control the quantity of released water by dual flush. This device is not only a simple structure but also easily using at the user's will.

Description

TECHNICAL FIELD OF THE INVENTION[0001]The present invention relates to a dual flush device for a toilet water tank. In particular, the present invention provides an improvement about flush device used in toilet water tank.BACKGROUND ART[0002]There is known that a commercially available flush toilet has a manually operation press handle which is mounted on a sidewall or on the tank lid. When the flush-valve inside the water tank is pulled up by means of pressing down the press handle, the water in the tank is released to the bowl from the drainage hole. But this mechanism makes the water drains out totally. The quantity of water can not be controlled as the user's demand. Furthermore, the prior art known to the inventor is TIPO pat. No. 89200711. The said patent has disclosed a device in which two handles connect to two flap-arms respectively. When the handle is pulled, it comes out a result of controlling one flap-arm or two flap-arms simultaneously operated, and a result of the ope...
