Title: Part-replaceable water dispenser for domestic animals

Abstract: A water dispenser detachably connected to a joint on a trough for supplying water to domestic animals is provided. The water dispenser mainly includes a stopper having an upper sleeve portion screwed into the joint, a lower tubular portion being beveled to provide a curved cut, and a control opening located in the stopper between the sleeve and the tubular portions. A control rod having a flange provided near an upper end thereof is disposed in the stopper with the flange closing the control opening and a lower part of the control rod extended into the tubular portion to expose from the curved cut. A ring nut is screwed to the sleeve portion to confine a spring to the stopper between the ring nut and the flange of the control bar, so that the spring normally pushes the flange downward to tightly close the control opening and thereby stop water from flowing from a water pipe screwed into an upper end of the joint into the trough via the water dispenser. When the control bar is biased, a gap is produced in the water dispenser between the flange and the control opening, allowing water to flow from the water pipe into the trough via the water dispenser.
