Abstract: Provided is a rotator structure of a nanomist-generating device which generates a nanomist by rotating a rotator having a conical shape, wherein a lower portion of the rotator is immersed in water and mist-scattering ports are disposed in an upper portion; the device generates a nanomist by scattering the water through the ports, the water being drawn up along an inner wall surface of the rotator by rotating the rotator; and a radius at an upper end of the ports is an upper portion radius R1, a height to the upper end of the ports from a waterline L is a drawing height H, and a mean angle between a horizontal line and the inner wall surface is a side surface mean angle ?1; and the angle ?1 is set within ?±5% of ? for ? satisfying a basic structure equation ?R1 sin3 ?+2 H cos ? sin2 ?+H cos3 ?=0.
