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 haircare appliance has a fixed body defining the air outlet, and a rotatable member rotatable relative to the fixed body. The air outlet has a first aperture located on a first side of the fixed body, and a second aperture located on a second side of the fixed body opposite to the first side of the fixed body. The rotatable member is rotatable from a first configuration in which the rotatable member permits airflow through the first aperture and blocks airflow through the second aperture, to a second configuration in which the rotatable member permits airflow through the second aperture and blocks airflow through the first aperture. The rotatable member is located internally of the fixed member.

Abstract: A wearable air purification system including a wearable support configured to be supported on or around a head region of a user, and an air delivery mask connected to the wearable support which is shaped to bound an air delivery region and to deliver a flow of air to the air delivery region. The air delivery mask includes an illumination source configured to illuminate the air delivery region, wherein the illumination source is directional and is oriented to target the air delivery region. The system or ‘air purifier’ is configured to direct light to the area occupied by the user's mouth when the air purifier is worn, as well as in some examples providing illumination to a mask or visor of the product itself. Examples herein are more visually appealing but the form of illumination means that the user's face is more visible to others which reduces facial features being obscured.
