Abstract
A hair dryer attachment includes a rotor impeller for converting a uniform stream of air from the hair dryer into a pulsating stream of air. A governor is provided on the rotor impeller or reduction gearing is provided between the rotor and the impeller to reduce the speed of rotation so that the pulsations are at a frequency perceptible to the user.
Claims5
An attachment for use with a hair dryer comprising:
- an attachment mechanism;
- a rotor impeller which, when in use with the hair dryer, is driven in rotation by the stream of air from the hair dryer and converts the uniform stream of air to a pulsating stream of air;
- and a governor associated with the rotor impeller for limiting the speed of rotation of the rotor impeller below that which would otherwise be attained without said governor.
An attachment for use with a hair dryer comprising:
- an attachment mechanism;
- an impeller which, when in use with the hair dryer, is driven in rotation by the stream of air from the hair dryer;
- a rotor including a baffle for converting the uniform stream of air to a pulsating stream;
- and reduction gearing connecting the rotor to the impeller so that the rotor rotates at a lower speed than the impeller.
