Abstract: A hairdryer including an ionising system and a heater wherein the ionising system comprises an ion producing electrode and the ion producing electrode extends along an external periphery of the heater. The ion producing electrode may extend along the heater to a downstream end of the heater. The ion producing electrode may extend along the heater from an upstream end of the heater. The heater may be generally cylindrical and the ion producing electrode extends along a radially outer surface of the heater. The ion producing electrode may have a first part which extends along a first axis and the first part extends along the external periphery of the heater. The ion producing electrode may have a second part, which extends along a second axis, wherein the second part extends radially inwards from the external periphery of the heater.

Abstract: An attachment is described for a haircare appliance. The attachment comprises an inlet for receiving an airflow, and a body comprising one or more pairs of outlets, each pair of outlets comprising a first outlet and a second outlet. The attachment further comprises a valve moveable relative to the body between a first position in which the valve occludes the first outlet and the airflow is discharged from the second outlet of each pair of outlets, and a second position in which the valve occludes the second outlet and the airflow is discharged from the first outlet of each pair of outlets. The valve comprises a sealing element that contacts the body at a position between the first and second outlets of each pair of outlets.
