Abstract: The present invention relates to a superparticle atomizing device and, more specifically, to a superparticle atomizing device having an inner plate provided at the upper part of an ultrasonic vibrator inside a housing and having a circulation passage formed at the circumference of the inner plate of the inside of the housing by using the rapid flow rate of the air to be ventilated to the inside of the housing through a blower, and thus only liquid microparticles generated at the lower region of the inner plate by the ultrasonic vibrator are pulled up to the upper region thereof, thereby allowing the liquid microparticles to be atomized through an atomizing hole and allowing the liquid microparticles to be rapidly diffused into the air with rapid ventilation air.
