Abstract
A fan-shaped air suction spray nozzle automatically adjusting an air suction speed is provided in the present invention, which includes a spray nozzle body and a liquid channel, the spray nozzle body being provided with a liquid channel in communication with a nozzle hole, and further includes a pressure groove and an air intake channel, wherein an inlet section of the liquid channel is in communication with the pressure groove, and the air intake channel is in communication with the liquid channel after penetrating through the pressure groove; an air intake orifice plate is installed in the pressure groove through an elastic damping apparatus, and a change of the pressure at an inlet of the liquid channel causes the air intake orifice plate to move between the pressure groove and the air intake channel; the air intake orifice plate is provided with several through holes of the same or different sizes, which are configured to change the air intake volume in the liquid channel as the air intake orifice plate moves in the pressure groove.
