LIQUID-AGENT-SPRAYING DEVICE, ELECTRIFYING/SPRAYING HEAD, AND LIQUID-AGENT-SPRAYING METHOD

摘要

A liquid-agent-spraying device equipped with a liquid-agent supply apparatus for pressure-supplying an aqueous-liquid agent via a tube, an electrifying/spraying head which electrifies and sprays particles of the liquid agent supplied by the liquid-agent supply apparatus, and is positioned in a spraying compartment, and a voltage-application unit for applying an electrifying voltage to the electrifying/spraying head, wherein the electrifying/spraying head is provided with: a nozzle for spraying the liquid agent into an exterior space; a liquid-agent-side electrode unit for contacting the liquid agent, and positioned in the interior of the nozzle; a deflection/spraying member for deflecting, in a desired direction, the liquid agent discharged from the nozzle, and after forming a film flow, dividing/separating the same into a particle-group flow, and spraying; and an induction-electrode unit positioned near the division-separation section of the film flow.
