A water shutoff and discharge control device for sprinklers comprises a water intake assembly mounted to a support seat and swung back-and-forth by a sprinkling control assembly wherein the water intake assembly has a tube with multiple bores drilled thereon for the mounting of a sealing strip equipped with multiple spray nozzles and water-sealing areas. Both end sections of the tube are disposed multiple control channels each connecting to the interior of the tube for the extension of a control shaft with a plug mounted thereto. Each plug having an inlet aperture and an abutment surface is corresponded to a water-sealing area of the sealing strip to reveal a movement space there-between, permitting the plug flushed by the water flow to climb upwards and, depending on the movement of the control shaft, to switch in position relative to the spray nozzle for easy control of water shutoff or discharge thereby.
