ELECTROSTATIC SPRAY APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a pesticide spray apparatus free from spray variance due to temperature difference and having the high arrival rate and the deposition rate of spray particles to an objective plant even in a high temperature condition like that in a glass house. SOLUTION: Inclined grooves 10A are formed by cutting on the tip part of a pressure valve 10 of a spray nozzle constituting a spray head. A circular discharge electrode part 7 is surrounded by an electric field relaxation member so that the voltage in the supply of high voltage from a DC high voltage generation apparatus has uniform potential and a sharp acicular or projected electrode penetrating through the electric field relaxation member is properly formed in a discharge electrode part.
