Title:
ELECTROSTATIC SPRAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/082278
Kind Code:
A1
Abstract:
Provided is an electrostatic spray device having a compact configuration that does not obstruct movement of a nozzle and the like, said electrostatic spray device making it possible to obtain a predetermined spray state in an atomized liquid that is sprayed. The electrostatic spray device is provided with: a voltage application means that applies voltage between a liquid spray section and an unlike pole section functioning as an unlike pole with respect to the liquid spray section, thereby causing electrostatic force to be generated; and an equipotential line adjustment electrode that is formed from a conductive material and that adjusts an equipotential curve appearing around a nozzle. The equipotential line adjustment electrode is configured so as to obtain an equipotential curve that is curved at least partially in a more gentle manner than the equipotential curve appearing near the front side of the nozzle when the equipotential line adjustment electrode is not arranged in the electrostatic spray device. The equipotential line adjustment electrode is configured so that it is possible to arrange said equipotential line adjustment electrode near the outer circumference of the tip of the nozzle and thereby obtain the aforementioned equipotential curve having a gentle curve. In addition, the equipotential line adjustment electrode is configured so as to have the same potential as the liquid spray section.
