1. A hair-treatment device comprising:
a blower assembly located within a blower device body and operable to supply a drying-air stream flowing in a first direction; a vacuum assembly operable to supply a return-air stream flowing in a second direction that is different from said first direction and direct said return-air stream through said blower device body; a housing having a proximal end coupled with said blower device body and an opposed distal end, said housing including a passage extending between said proximal and distal ends and operably connected with said blower assembly to conduct said drying-air stream supplied by said blower assembly, said passage having an annular outlet through which said drying-air stream exits said housing, said housing further including a passageway extending between said proximal and distal ends and operably connected with said vacuum assembly to conduct said return-air stream supplied by said vacuum assembly, said passageway having an air intake through which said return-air stream enters said housing, said air intake and said annular outlet being located at said housing distal end, said air intake being disposed inboard of said annular outlet; and a smoothing element disposed in covering relationship to said air intake and having a hair-smoothing surface facing away from said passageway, said smoothing element defining a plurality of openings sized to permit passage of said return-air stream therethrough while substantially preventing passage of a user's hair therethrough and into said passageway, said hair-smoothing surface being substantially continuous between said openings, said smoothing element being substantially devoid of structure extending outwardly past said hair-smoothing surface. |
