Abstract
The disclosure relates to the technical field of blow dryers, and in particular to a compact continuous high-speed blow dryer. By improving optimized design of an air duct, while a wind resistance coefficient of guide vanes is reduced, values of flow rates in paths can be ensured, so that a fluid can be led out of the air duct linearly and uniformly and a fan blade can operate stably. Auxiliary support structures such as a spring, bearings and an air guide pad further stabilize a position of the fan blade and avoid centrifugal vibration of the fan blade, which eventually reacts on a rotating shaft and affects rotational efficiency of the rotating shaft. Therefore, an operating environment of the fan blade is greatly improved, and overall efficiency of the fan is improved, Moreover, since the operating environment of the fan blade is optimized, stability of the fan is enhanced, and further, service life of the fan is prolonged.
