摘要： An attachment for a haircare appliance, the attachment having an air inlet, a curved surface, and first and second air outlets, the curved surface adjacent to and downstream of the first and second air outlets and the first and second air outlets for directing airflow in respective opposite directions across the curved surface. The attachment has a switching member for switching airflow between the first and second air outlets, the switching member movable from a first switch position in which airflow passes through the first air outlet across the curved surface and does not pass through the second air outlet, to a second switch position in which airflow passes through the second air outlet across the curved surface and does not pass through the first air outlet. The attachment has a retention mechanism for retaining the switching member in one of the first and second switch positions in the absence of an applied force to the switching member by a user of the haircare appliance. Airflow exiting the air outlet generates a first force to attract hair toward the curved surface, and a second force to push hair away from the curved surface.

摘要： A fan assembly, comprising a fan body comprising an inlet surface defining an air inlet. A motor-driven impeller contained within the fan body generates an airflow. A filter assembly is arranged to removably engage with the fan body and to cover at least a portion of the inlet surface when engaged with the fan body. The filter assembly comprises a filter and a housing for the filter, the housing being provided with a filter retention assembly for releasably retaining the filter in the housing, and a user interface for actuating the filter retention assembly to release the filter from the housing. Upon actuation of the filter retention assembly via the user interface, the filter is free to slide relative to the housing. Preferably, the user interface is positioned on the housing.
