Electrostatic Cosmetic Deposition via Nozzle and Target Electrodes

The patent replaces non-electrostatic mechanical deposition mechanisms with an electrostatic system. The electrostatic nozzle charges cosmetic particles electrically, and the target electrode on the skin surface creates electrostatic attraction to control particle deposition. This substitution enables precise control over application duration and uniformity by adjusting electrostatic parameters rather than relying solely on mechanical spray control.

The patent introduces dynamic control through the target electrode that can be activated or deactivated to control particle attachment and detachment. By dynamically adjusting the electrostatic field on the skin surface, the system can extend or reduce the duration of cosmetic application. The charged particles remain attached as long as the electrostatic attraction is maintained, providing controllable application duration.

The patent integrates multiple functions into the electrostatic deposition system. The same electrostatic nozzle that charges particles also controls their release, while the target electrode on the skin surface serves both as a charging mechanism and an attachment control. This multi-functionality reduces the need for separate mechanical components, thereby managing device complexity while achieving precise deposition control.

The patent employs periodic action through the controlled activation and deactivation of the target electrode. By periodically applying electrostatic attraction, the system can control when particles attach and detach from the skin surface. This periodic control mechanism enables adjustable application duration without requiring complex mechanical timing devices, as the electrostatic field itself serves as the timing control.
