Abstract:
PURPOSE: Control device and method of the droplet motion in the electric field are provided to precisely control the amount of single droplet sprayed by forming strong electric field on the end of a spray tip. CONSTITUTION: A control device of the droplet motion in the electric field comprises a first electrode(10), an insulator(11), a spray tip(21) and a second electrode(20). The insulator is arranged on the first electrode. The spray tip is installed on the upstream of the insulator and sprays traces of fluid in a droplet type. The second electrode makes contact with the fluid provided through the spray tip. The first and second electrodes form potential difference and form the electric field at the end of the spray tip. The first electrode is formed through one of high voltage application and ground connection. The second electrode is formed through the other of high voltage application and ground connection.
