Abstract: An attachment for a haircare appliance, the attachment having a main body including an air inlet and an air outlet. The attachment has a guide for directing airflow from the air outlet across a curved surface of the main body, such that airflow directed by the guide generates a first force to attract hair toward the curved surface, and a second force to push hair away from the curved surface. The main body is rotatable relative to the guide between a first position in which airflow exiting the air outlet is directed by the guide and a second position, in which airflow exiting the air outlet is not directed by the guide.

Abstract: An attachment for a haircare appliance, the attachment having an air inlet, an air outlet. The attachment has a curved surface adjacent to and downstream of the air outlet, and a rib positioned such that the rib interacts with airflow exiting the air outlet to align the airflow exiting the air outlet. 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.

Abstract: An attachment for a haircare appliance, the attachment having an air inlet, first and second air outlets, and a curved surface adjacent to and downstream of the first and second air outlets. The attachment has a 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.
