The invention discloses a water cup facilitating medicine taking of old patients. The water cup comprises a cup body, a cup cover is connected to the top of the cup body, a rotating plate is arrangedat the inner side of the top of the cup cover, medicine storing grooves are formed in the surface of the top of the cup cover, a medicine pouring hole is formed in one side of the surface of the cup cover, a shaft rod is arranged in the center of the cup cover in a penetrating manner, one end of the shaft rod is fixed to the surface of the cup cover, and a rubber sleeve ring is fixed on the side wall of the rotating plate. According to the water cup, through the design of the rotating plate, the machine storing grooves are isolated, through the design of the machine storing grooves, classifiedmedicines can be stored on the cup cover, and the carrying is convenient, through the design of the rubber sleeve ring, the rubber sleeve ring is positioned on the side wall of the rotating plate, further, good skidding preventing and friction preventing effects are achieved, then the rotating plate seldom rotates when no external force exists, so that the loss of machines is avoided, through thedesign of connecting shafts, the connecting shafts are inserted in connecting grooves, so that a rotating block and the rotating plate are connected together, and therefore, a user can rotate the rotating plate for getting the medicines.
