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.

An electrospray atomizing device that sprays at a constant rate comprises a main unit containing a circuit board, an electrode plate, liquid tanks and syringes. The electrode plate includes the sealed liquid tanks and the syringes, and the circuit board connects electric current to the electrode plate and the syringes. The present invention further includes a power mechanism and a dosing device. The power mechanism drives a screw to ascend or descend, pushing the pistons of the dosing device through a speed changer. The syringes are connected with the liquid tanks. When the pistons are linked by the power mechanism and the speed changer to ascend, the liquid in the liquid tanks is sprayed at a constant rate through the syringes, forming mist which carries negative ions. When the pistons descend, the ambient liquid is sucked into the liquid tanks through the syringes, waiting for a next electrospray.

Proposed is a multi-needle head. The multi-needle head includes at least one adapter mounted with a needle in which liquid is discharged therethrough, and includes a holder in which the adapter is fixed. An O-ring having an outer diameter thereof larger than a width of a body of the adapter is coupled to the body of the adapter, a fixing hole into which the body of the adapter is inserted is formed in the holder, and an O-ring fixing portion having an inner diameter thereof larger than an inner diameter of the fixing hole is formed in the middle of the fixing hole such that the O-ring is positioned at the O-ring fixing portion. A vertical width of the O-ring fixing portion is larger than a vertical width of the O-ring, thereby allowing a height of the adapter that is fixed to the holder to be adjusted.

A sintered magnet body is held in a grounded jig exhibiting excellent electrical conductivity, a rare-earth-compound powder is charged and sprayed on the sintered magnet body to electrostatically coat the sintered magnet body with the powder, and thus apply the powder to the sintered magnet body. The sintered magnet body having the powder applied thereto is heat treated to produce a rare-earth magnet. As a result, the rare-earth-compound powder can be uniformly applied to the surface of the sintered magnet body, and the application operating can be performed extremely efficiently.

The disclosure relates to an electrode arrangement for the electrostatic external charging of paint on a rotary atomizer, which has an atomizer housing with an end-face tu-bus which preferably extends coaxially with the rotation axis of the rotary atomizer towards a bell cup.
