Abstract
A wick-based emanation device for dispensing a volatile liquid is disclosed. The dispensing device includes a housing and a fan mounted in the housing for generating an air stream used for dispersing the volatile liquid. Walls of the housing form an enclosure for mounting the fan and for receiving an exposed portion of the wick therein. A retention structure is provided for coupling the wick to the housing and securing the wick in the air stream generated by the fan. The volatile liquid migrates along the wick from the reservoir to the exterior of the container where it is evaporated from the surface of the wick by forced airflow generated by a motorized fan mounted in the housing. The wick is formed to have a width dimension W which does not exceed 1.2 times a dimension R of a blade of the fan extending from the fan axis of rotation to an edge of the fan blade farthest from the axis of rotation.
