    Abstract: The electrostatic spray device includes a liquid sprayer including a nozzle that spouts a liquid; a voltage applicator that applies a voltage between the liquid sprayer and a heteropolar portion functioning as a pole opposite a pole of the liquid sprayer to generate an electrostatic force for causing the liquid to separate from a distal end of the nozzle in a charging state; and a stabilization electrode that maintains a stable spraying state of the liquid even when a pressure is applied to the liquid to supply the nozzle with the liquid. The stabilization electrode has an electric potential identical to an electric potential of the liquid sprayer, and is disposed near the nozzle such that a jet portion formed at a front of the nozzle by a linear extension of the liquid has a length longer than a length of the jet portion before the stabilization electrode is provided.

    Abstract: An electrostatic spray device including a voltage applicator and an isoelectric line adjustment electrode. The voltage applicator applies a voltage between a liquid sprayer and a heteropolar portion functioning as a pole opposite from a pole of the liquid sprayer to generate an electrostatic force. The isoelectric line adjustment electrode is made from a conductive material and adjusts equipotential curves appearing so as to surround the nozzle. The isoelectric line adjustment electrode obtains the equipotential curves at least partially drawing curvature gentler than curves of equipotential curves appearing near a front side of the nozzle in a state where the isoelectric line adjustment electrode is not disposed. The isoelectric line adjustment electrode is located near an outer periphery at a distal end of the nozzle and has an electric potential identical to an electric potential of the liquid sprayer such that the equipotential curves drawing the gentle curvature are obtained.
