A new type of high-efficiency atomization device

Abstract

The present invention discloses a novel and efficient atomization device, which includes an ultrasonic transducer, a cavity, a protrusion, a ring, a compressed air inlet and a liquid injection port. The ultrasonic transducer is arranged at the bottom of the cavity and is used to generate ultrasonic atomization in the cavity. The liquid injection port is arranged at the bottom of the cavity and is used to control the inflow or outflow of liquid into or out of the cavity. The protrusion is arranged on the side wall of the cavity and on the ring and is used to impact and break the mist droplets. The surface of the protrusion is coated with a superhydrophobic coating, which is used to prevent droplet attachment and improve the effect of droplet impact and breakage, forming smaller atomized droplets. The compressed air inlet is arranged at the bottom of the cavity and is used to control the injection of compressed air and drive the mist droplets to impact the protrusion. The ring is arranged at the upper end of the cavity and is used to fix the protrusion thereon and discharge the mist. The present invention drives the mist to be discharged upward by compressed air, so that the atomized droplets impact the triangular protrusion, forming mist droplets with smaller sizes, ensuring the controllability of the size, speed and stability of the mist droplets.
