  • Patent number: 5435327
    Abstract: A hand-held grooming device has a comb which protrudes from a slot through which air is drawn and used by a fan driven by an electric motor. Loose hairs and dandruff are thus drawn into the device and collected by a filter. The same air is then blown out through an orifice which can be rotated about the axis of the device, at a point adjacent the point from which the air was drawn into the device. A heater can be switched on to heat the exhaust air. Thus, the same air which is drawn into the device to remove loose hairs and dandruff, after such removal is returned to the same location to dry or warm or cool the location from which the hair was withdrawn. The device is useful not only in connection with hair but also the removal of lint or dust from clothing.
