Abstract: An attachment for a hair care appliance, the attachment including a main body having an outer surface, a hair engaging member, an airflow inlet for receiving airflow from the hair care appliance, and an airflow outlet between the main body and the hair engaging member. The airflow from the airflow outlet is configured to attach to the outer surface. The attachment further includes an airflow separator downstream of the airflow outlet. The airflow separator is configured to cause airflow to separate from the outer surface in use.

Abstract: An attachment for a hair care appliance, the attachment including a main body, a first hair engaging member and a second hair engaging member, an airflow inlet for receiving airflow from a hair care appliance, a first airflow outlet between the first hair engaging member and the main body, a second airflow outlet between the first hair engaging member and the second hair engaging member, and a third airflow outlet between the second hair engaging member and the main body. The attachment has a first configuration in which airflow is directed out of the first, second and third airflow outlets in a first direction in use, and a second configuration in which airflow is directed out of the first, second and third airflow outlets in a second direction different to the first direction, in use.

Abstract: Disclosed herein, a haircare appliance using wireless transmission of information and/or energy between the appliance's main body and an accessory. The appliance has a main body with a processing element, a communication element, and a blower for generating an airflow. The main body has an attachment region for connecting an accessory. The accessory has a sensor element to determine a sensor reading, a processing element, and a communication element. The accessory is selectively attachable to the main body at the attachment region, and when attached to the main body, it can receive the airflow from the blower, and discharge the received airflow towards the hair of a user. The main body and accessory have a communication connection for bidirectional communication. The bidirectional communication is a wireless communication connection, and energy for operating the sensor element is provided by the wireless communication and/or a separate wireless energy transfer connection.

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 signal generator configured to generate a signal indicative of hair contacting the haircare appliance. The airflow generator includes a first operating mode in which the airflow generator generates airflow at a first flow rate, and a second operating mode in which the airflow generator generates airflow at a second flow rate greater than the first flow rate. The airflow generator is configured to operate in the first operating mode in the absence of the signal and in the second operating mode in the presence of the signal.

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 having a first cross-sectional area, and a second aperture having a second cross-sectional area greater than the first cross-sectional area. The haircare appliance has a first configuration in which airflow through the second aperture is inhibited, and a second configuration in which airflow through the second aperture is uninhibited.
