Abstract
The present application relates to a liquid-evaporate delivery device which relies on the efficient use of air currents to deliver liquid evaporate to airspace around the device. Efficient air currents may be provided by rotating the air currents around the wick, by providing a helical channel for the air to flow around the wick, and/or by aligning a fan with the longitudinal axis of the wick.
