Abstract
An evaporation device 2 is disclosed for the evaporation of volatile substances, in particular insecticides and aromatics, which includes a housing 13 which contains a heating element and a container 50 for a substance to be evaporated. This container 50 contains a wick which is associated with the heating element with a wick end 30 protruding from container 50. The heating element can be longitudinally displaced near the container 50 in the housing 13 relative to the wick end 30 to adjust the degree of evaporation. According to the invention, the heating element is carried on a movable heater assembly that can be displaced longitudinally in the housing relative to the wick end. The movable heater assembly can be fixed in different positions relative to the wick end 30 and the longitudinal direction of the wick axis for the adjustment of the degree of evaporation.
