Devices and Methods for Improved Delivery of Volatile Liquids

An emanation system comprising and emanation device and a replaceable refill of liquid, wherein the refill comprises:

• a sealed reservoir of a 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;
• a porous wick having a length which extends from the interior of the reservoir to the exterior thereof;
• a reservoir seal having at least two apertures, wherein the wick extends through one of the apertures;
• and
• a hollow liquid conduit which extends from the interior of the reservoir to engage with one of the apertures;
• and wherein the device comprises:
• an air pump;
• a fluid conduit in fluid communication with the air pump such that, in use, air pumped by the pump will flow through the fluid conduit;
• a nozzle located at the end of the fluid conduit remote from the air pump;
• a ejector constriction provided in the fluid conduit adjacent or substantially adjacent the nozzle;
• a liquid conduit engaging member provided adjacent the ejector constriction and in fluid communication with the fluid conduit at one end thereof, and configured at the other end to, in use, engage the hollow liquid conduit in the refill.
