摘要

An emanation device is described which comprises: a replaceable refill 10 of volatile liquid containing one or more active materials wherein the active material comprises at least one of: a fragrance; an insecticide; a fungicide; a pesticide; a sanitising material; and/or a pharmaceutical; wherein the refill comprises a sealed reservoir containing said volatile liquid and a porous wick 9 which extends from the interior of the reservoir to the exterior thereof; and wherein the device comprises: an air pump 2; a fluid conduit 5 in fluid communication with the air pump such that, in use, air pumped by the pump will flow through the fluid conduit; a nozzle 6 located at the end of the fluid conduit remote from the air pump; a ejector constriction 14 provided in the fluid conduit adjacent or substantially adjacent the nozzle; a liquid conduit 8 provided adjacent the ejector constriction and in fluid communication with the fluid conduit at one end thereof, and open at the other end to receive liquid therein; characterised in that the liquid conduit is located within the porous wick. The liquid conduit may be made from a substantially rigid material and the open end of the liquid conduit provided with a sharpened point or the like for penetrating the wick. Also claimed is a method of emanating a volatile liquid using the device. The device may be able to receive more than one refill.
