Cyclone blower barrel hair dryer configuration

Abstract

The present disclosure relates to a hair dryer with a cyclone blast barrel that discharges airflow farther and faster by means of a helical blast barrel structure, and particularly, to a hair dryer comprising: a first blast barrel and a second blast barrel for discharging air in cyclone form; a heater that generates heat of a predetermined temperature; a fan-motor for rotating a fan to blow air; and a cover for providing an enclosure for securing components and a protection against impacts, wherein the hair dryer strongly discharges air at high speed for the same output of a drive motor, and has the effect of discharging air that is uniform in temperature.
