ABSTRACT:
A heater device includes an external casing (1), an inner part (2), a pair of contact elements (3) and (3′), and a jack plug (4). Contact elements (3) and (3′) define pairs of salient projections (17) and (18) which allow connection of the jack plug (4) in two positions of rotation, at 90° to each other, and prevent connection in an intermediate position. The heater device operates to heat a wick which emerges from a vessel containing an active substance to cause the evaporation of the substance. The vessel is retained on the lower end of the heather device by a ring (26) provided on inner part (2).
