Background technique

Inductive charge spraying technology is a method to improve the spray characteristics by controlling the movement of droplets through electrostatic interaction. This technology has been widely used in electrostatic spraying, film preparation, spray forming, electrostatic capture, pesticide spraying and other fields. In this method, the mist droplets carry the opposite charge to the electrode, and under the action of the electric field force, the fine mist droplets with less kinetic energy will entrain reversely along the electric field lines to the jet. Conventional axial-flow air delivery technology performs well on large sprayers, but for small or hand-held sprayers, the limitation of fan power and volume will amplify the damage caused by entrainment, for example, the droplets are entrained and deposited on the electrode, When the voltage rises, a corona discharge occurs at the effusion site, resulting in a decrease in the spray current; secondly, the coverage of the entrainment is often larger than the outlet area of the tapered air duct, resulting in the return of the droplets to form an effusion on the outer wall of the air duct, not only It wastes liquid medicine and affects the user experience of the product at the same time.
