Evaporation device for volatile substances
First Claim
1. An evaporation device for volatile substances such as insecticides, aromatics, and the like comprising:
- a housing;
a heating unit disposed in said housing having a heating block;
an electric resistance element carried by said heating block to heat the heating block;
a container for a substance to be evaporated to be carried by said housing;
a wick inserted into said container having a wick end protruding from the container for the evaporation of the substance in said container;
said electric resistance element including a rod-shaped resistance body coated in at least some areas with a resistance layer said resistance layer being processed by one of cutting and grinding in some areas to provide a desired resistance value according to the evaporation temperature required for evaporation of the substance in said container so that a heating unit with small dimensions and miniaturized evaporation device are provided.

Abstract
The present invention relates to an evaporation device 1 for volatile substances, in particular insecticides and/or aromatics, which includes a housing 2 and a heating unit 10 located therein. Heating Unit 10 comprises a heating block 11 in which an electric resistance element 15 is contained for heating. In addition device 1 includes a container 3 that can be connected to housing 2 for a substance to be evaporated. A wick 6 can be inserted into the container with a wick end 8 protruding from the container 3 for the evaporation of the substance contained in the container 3 to be heated by the heating unit. According to the invention, electric resistance element 15 advantageously includes a rod-shaped resistance body 17 coated, at least in some areas, with a resistance layer 16 that is cut to provide a predetermined resistance value according to the composition of the substance to be evaporated. In this manner, a heating unit 10 with small dimensions and miniaturized evaporation device 1 is provided for the evaporation of volatile substances.
