Under a certain pressure, the oil passes through the annular groove at the intersection of the small holes of the diverter, and then enters the cyclone chamber in the center of the cyclone through the tangential groove of the diverter, generating high-speed rotary motion and spraying through the central hole. Under the action of centrifugal force, the oil overcomes its own viscosity and surface tension and is crushed into fine oil droplets, forming a conical atomization torque with a certain angle.
