Abstract: The present invention relates to an ultrasonic humidifier forming a swirl flow and, more specifically, to the ultrasonic humidifier which forms a shape of a swirl flow where moisture particles rotate by jetting spiral air upward and prevents a backflow of the moisture particles. According to the ultrasonic humidifier where a plurality of ultrasonic oscillation devices for forming fine moisture particles are installed on a bottom surface of a water tank, a transfer pipe for introducing external air is formed in a center portion of the water tank, a blower fan for introducing external air is installed on a lower side of the transfer pipe, an air guide member is installed on the outside of the water tank at an interval, and a swirl flow formation unit for allowing the moisture particles combined by jetting the introduced air in a spiral shape to form the swirl flow protrudes from the inner circumferential surface of the air guide member. Therefore, the present invention has the swirl flow formation unit protruding from the inner circumferential surface of the air guide member to allow the introduced external air to be injected in the spiral shape upward so as to enable the air to be combined with the fine moisture particles injected through a discharge unit and form the shape of a rising swirl flow by rotating. Therefore, the moisture particles ascend higher to be diffused in a large space, and the condensation of moisture on the bottom surface can be minimized. In addition, an inner cover is coupled on an upper side of the transfer pipe so as to prevent the backflow of the moisture particles and always maintain uniform air pressure.
