摘要： Provided is an electrostatic spraying device capable of spraying liquid, such as paint, onto a sprayed object in a stable manner. The electrostatic spraying device of the invention releases liquid in an electrically-charged state from a nozzle using an electrostatic force generated by voltage application and thus sprays the liquid onto a sprayed object. The electrostatic spraying device comprises a nozzle head provided with the nozzle comprising a plurality of nozzles made of conductive or semiconductive material and a voltage application device configured to apply voltage between the nozzles and a heteropolar portion (sprayed object) that is heteropolar to the nozzles and thus generate the electrostatic force. The nozzles are so arranged that distance between axes L of at least adjacent nozzles increases with increasing distance from the nozzle head.

摘要： 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.

摘要： 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.

摘要： An electrostatic spray apparatus includes: a voltage application device; a liquid spraying section including a nozzle for spraying a liquid a charged state by utilizing an electrostatic force generated by the voltage application device; and a coating prevention electrode for generating an electric field between the coating prevention electrode and a portion of the object to be coated on which the liquid is not to be coated. The voltage application device applies a voltage such that, when a potential of the object to be coated is a reference potential, a potential of the liquid spraying section assumes a first potential different from the reference potential, and a potential of the coating prevention electrode assumes a second potential. The second potential is a potential different from the reference potential, and a direction of polarity of the second potential is to the same as a direction of polarity of the first potential.
