Abstract
Various exemplary illustrations of an electrode assembly for an electrostatic atomizer, for example for a rotation atomizer, and exemplary methods of making and/or using the same, are disclosed. An exemplary electrode assembly may include an electrode holder arrangement for holding at least one electrode creating an electrostatic field about a symmetrical axis, wherein there is a dielectric material for influencing a discharge current component extending in the direction of the symmetrical axis.

An electrode assembly for an electrostatic atomizer, the atomizer having an axis of symmetry and having a first housing and a second housing and an electrode holding area established by a difference in diameter between the first and second housings, the electrode holding area including a first thread, the electrode assembly comprising:
- an annular electrode holding device, configured to fit around at least the first housing and for holding a plurality of electrodes that generate an electrostatic field, the electrode holding device including a second thread that engages with the thread of the electrode holding area to threadedly connect the electrode holding device to the housing,
- wherein the first and second threads are coaxial to an axis of symmetry and form a labyrinth and the labyrinth is defined by a dielectric material and is configured to extend a discharge current path in a direction of the axis of symmetry;
- and
- wherein an angle between the electrode and the axis of symmetry is greater than 40° and less than 70°.
Atomizer housing element for an electrostatic atomizer, wherein the electrostatic atomizer has an atomizer housing with a first housing element with a first diameter and a second atomizer housing with a second diameter, the second diameter being greater than the first diameter, wherein the housing element is suitable for receiving a support device for a spray element, the atomizer housing further comprising:
- an electrode holding area defined by a difference in diameter between the first diameter and the second diameter, the electrode holding area for holding an electrode assembly;
- and the electrode holding area includes a screen which is received by the electrode assembly, wherein the screen defines a labyrinth, coaxial to a central axis, for a discharge current, wherein the labyrinth is defined by a dielectric material and is configured to extend discharge current path in a direction of the central axis and wherein each electrode in the electrode assembly is disposed at an angle greater than 40° and less than 70° relative to the axis of symmetry.
