Abstract
An electrically heated, hand-held portable facial sauna appliance has a top air inlet, side air inlet, an air flow adjustment arrangement and a fan to mix ambient air with steam generated from a quantity of water contained in an internal steam generating chamber having an associated electric heater and a bottom fill opening such that the appliance must be inverted to fill the chamber with water. A water trap and overflow arrangement in the container ensures that the chamber cannot be overfilled and enables the appliance to be overturned during use without leaking. The appliance is provided with attachments in the form of a facial mask, concentrator tube, brush and sponge, each designed to fit over a steam-air mixture outlet and control the quantity of air entering through the top air inlet.
