Airflow Concentrator for Hair Dryer

Abstract

The present utility model discloses an airflow concentrator for a hair dryer, comprising a base sleeved onto the air supply outlet of the hair dryer at the bottom, and a rolling mechanism, wherein two sets of through holes of positional correspondence are provided on the two sides of the top of the base, and the rolling mechanism mounted in the top of the base by the through holes can realize rolling movement. The beneficial effects are: the friction occurring when an airflow concentrator in the prior art is applied to long hair for styling and drying is improved; on one hand, the presence of a metal rolling mechanism can avoid the damage to the hair cuticle on the hair surface, on the other hand, the metal rolling mechanism can be easily heated by the hot air, and the repeated movement of the rolling wheel will achieve hair straightening and styling effect.
