Abstract
A housing has a dispensing outlet () and contains: a liquid supplier () for supplying liquid containing at least one volatile component to a liquid outlet (); an electric field provider () for causing liquid issuing from the liquid outlet to provide electrically charged droplets from which at least a part of the at least one volatile component evaporates to produce vapour; a collection receptacle () for collecting electrically charged droplets to inhibit the electrically charged droplets from passing through the dispensing outlet; an attraction electrode () for attracting electrically charged droplets into the collection receptacle (); and a flow director () for directing vapour away from the collection receptacle () and towards the dispensing outlet ().
