Evaporation device for volatile substances
First Claim
1. An evaporation device for evaporating volatile substances such as insecticides and aromatics of a type having a housing containing a heating element, with a container for the volatile substance to be evaporated disposed in the housing, a wick which can be heated by the heating element with a wick end protruding from the container along a wick axis, whereby the heating element can be displaced relative to the wick end for an adjustment of the degree of evaporation, and wherein the improvement comprises:
- a moveable heater assembly carried within the housing for longitudinal displacement relative to the wick axis and relative to the housing;
a heating element carried by said moveable heater assembly in a manner that said heating element is adjacent a portion of said wick end for heating said wick portion; and
an adjustable connection operatively associated with said heater assembly for positioning said heater element at different axial positions relative to the wick end and the wick axis to adjust the degree of evaporation.

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.
