Abstract
A spray nozzle configured to atomize and spray liquid by gas. The spray nozzle includes a liquid dripping prevention mechanism configured to prevent dripping of the liquid from the spray nozzle caused as a result of electrically charged fine particles of the liquid sprayed from the spray nozzle being attracted to and adhering to the spray nozzle.
Claims8
A spray nozzle configured to atomize and spray liquid by gas, comprising:
- a liquid dripping prevention mechanism configured to prevent dripping of the liquid from the spray nozzle caused as a result of electrically charged fine particles of the liquid sprayed from the spray nozzle being attracted to and adhering to the spray nozzle,
- wherein the liquid dripping prevention mechanism is provided in contact with a nozzle tip portion, and includes a self-discharge electrode made of a metal material for inducing a corona discharge to discharge electric charges accumulating at the nozzle tip portion.
