The present invention discloses an improved handheld sprayer structure comprising an electric sprayer and a liquid container. The liquid container is filled with an appropriate amount of liquid, and this device is held by a hand, and a press button is pressed to trigger a start switch, such that a drive gear installed on a motor transmission shaft drives a plurality of wheels installed on a large gear to compress a hose to produce a suction, so as to suck the liquid in the liquid container upward, and spray the appropriate amount of liquid continuously and steadily from a spray head.
