Aroma-generating automobile cigarette lighter

A cigarette lighter adapted to function also as an aroma generator, the lighter being insertable into a socket having terminals which are connected to a power source, one of which is a latching bi-metallic element, said lighter comprising:

• A. a case that fits into the socket;
• B. a spring-biased hollow plunger formed from a cylindrical metal shell having a vented cylindrical cage projecting from its open rear end and terminating in a ring serving as the plunger knob;
• C. an electrical heater unit attached to the front end of the shell and which in the inactive state of the plunger lies within the case, the unit having contacts, whereby when a user presses in the plunger, the contacts are engaged by the socket terminals to energize the unit and the unit is then latched by the latching element, the resultant heat being transferred to the interior of the shell and also acting to deform the latching element, thereby disengaging the terminals and causing the released plunger to return to its inactive state;
• and
• D. a removable vented cartridge insertable into the plunger and having therein a heat-responsive, aroma-generating element that is activated by the interior heat to exude an aromatic vapor, said heater unit being formed by a cup-shaped bezel and a spiral strip of electrical resistance material nested in the bezel, one end of the strip being connected to the bezel which is engaged by the latching terminal, the other end of the strip being connected to a center electrode that is engaged by the other terminal, said center electrode having a metal rod attached thereto which extends into the interior of the metal shell to a point adjacent said aroma-generating element to transfer heat from the heater unit to the element and thereby promote the generation of the aroma.
