The actuating device for a sprayer contains a control circuit to provide scheduled operations, a driving member to provide a torque, a power member to provide electricity to the control circuit and the driving member, an actuating member to exert pressure to the nozzle of the sprayer, a gear set to deliver the torque to the actuating member, and a casing member to house the foregoing components. The actuating member has a roughly quadrant shape with gear teeth on the arc and a peen besides the gear teeth. An adaptation member can be provided on top of the nozzle. The adaptation member has a socket to fit on the nozzle and a diametric elongated ridge interacting with the peen to provide closer and longer period of interaction to avoid insufficient exertion of pressure to the nozzle.
