Patent ID: 6850697

Claim:
A heater device for active substances, for holding a vessel containing a vaporizable substance, in which vessel is a wick through which by capillary action the vaporizable substance rises and reaches the end of said wick, said wick having an end extending from the vessel said wick end being placed in a corresponding neck of the heater device in which are provided heating elements for the wick, so that the heat generated causes the evaporation of the vaporizable substance, provided with means for electrical power supply, the heater device comprising: an external casing, an inner part, a jack plug, and first and second contact elements which form a third element, said third element being secured and mounted on the inner part wherein the heating elements include corresponding electrical resistors that are directly connected to the first and second contact elements, the first and second contact elements facing each other so that they may make contact with inner ends of pins of the jack plug, while the jack plug is retained inside a lateral neck of the casing such that it cannot move axially but may rotate to occupy two positions at 90° to each other, in which contact is made with the first and second elements, and an intermediate position in which the inner ends of the pins of the jack plug are not in contact with the first and second contact elements.
