  • Hair dryer with brush
    Patent number: 7584759
    Abstract: In a hair dryer with a brush emitting minus ion to a hair in brushing, effect of the minus ion for hair treatment is increased. The hair dryer is comprised of a main body and a brush unit detachably engaged with an air outlet of the main body. A plurality of ion outlets is provided on a housing of the main body and disposed outside of the air outlet so that minus ion is emitted toward the brush unit.
