Electrostatic spray head.

摘要

A spray head for a spray nozzle including a hood providing a surface extending forward from the nozzle and also supporting insulating mountings for electrodes energisable to exert an inductive charging field or spray from the nozzle. The surface is earthed or earthy in operation to encourage collection of stray or return spray and stop stray or return spray affecting the charging field by landing the electrodes or their mountings. The collected spray may be retained as liquid or caused to flow to projections to again leave the spray head as small droplets. The field from the electrodes may shape the spray.
