Abstract
A haircare appliance has an air inlet, an air outlet, and an airflow generator for generating an airflow from the air inlet to the air outlet. The air outlet has a first aperture at least partially defined by a first movable member, and a second aperture at least partially defined by a second movable member. Each of the first and second movable members are movable to vary a cross-sectional area of the respective first and second apertures, and movement of the first movable member causes movement of second movable member.
Claims22
An attachment for a haircare appliance comprising an air inlet for receiving an airflow, and an air outlet for emitting airflow, wherein the air outlet comprises a first aperture at least partially defined by a first movable member, and a second aperture at least partially defined by a second movable member, each of the first and second movable members movable to vary a cross-sectional area of the respective first and second apertures, wherein movement of the first movable member to increase the cross-sectional area of the first aperture causes a decrease in internal air pressure of the attachment in use, and wherein the decrease in internal air pressure causes movement of the second movable member to decrease the cross-sectional area of the second aperture.
A haircare appliance comprising an air inlet, an air outlet, and an airflow generator for generating an airflow from the air inlet to the air outlet, wherein the air outlet comprises a first aperture at least partially defined by a first movable member, and a second aperture at least partially defined by a second movable member, each of the first and second movable members are movable to vary a cross-sectional area of the respective first and second apertures, and movement of the first movable member causes movement of the second movable member due to a difference in air pressure of the haircare appliance in use when the cross-sectional area of the first aperture is varied by the first movable member.
