Claim:
A cedar oil evaporator, comprising: (a) a housing having openings therein for the ventilation of air; (b) a reservoir contained within the housing; (c) cedar oil contained within the reservoir; and (d) a plurality of carriers partially immersed in the cedar oil configured to wick cedar oil away from the reservoir for dispersing cedar oil via air that passes through the housing, (e) wherein each carrier includes first and second extents, (i) the first extent of each respective carrier representing ten percent or less of the overall length of the respective carrier being received within the reservoir, and (ii) the second extent of each respective carrier representing the remainder of the overall length of the respective carrier being randomly coiled within the housing such that a plurality of interstices arc defined, whereby a surface area of the carrier is exposed to air that passes through the ventilation openings in the housing; (f) wherein the overall length of each carrier is greater than the greatest dimension of the housing; (g) wherein the interstices include interstices of differing sizes, at least some of the interstices having an area greater than a cross-sectional area of any of the carriers; (h) wherein at least some of the interstices arc defined collectively by more than one carrier of the plurality of carriers; and (i) wherein each carrier is disposed entirely within the housing; (j) wherein at least one complete coil is formed by each of the randomly coiled second extents of the plurality of carriers.
