ABSTRACT:
An automobile cigarette lighter adapted to generate an aromatic vapor, the lighter being releasably retained within a dashboard socket having terminals therein connected to the battery of the vehicle. The lighter is constituted by a cylindrical shell having telescoped therein a spring-biased plunger. A disc-shaped heater element attached to the front end of the plunger is normally disposed at a position spaced from the socket terminals. A knob attached to the rear of the plunger projects beyond the rear end of the shell. When the knob is pressed in by a user, the plunger is advanced relative to the shell to cause the heater contact to engage the socket terminals and to be latched thereto by a bimetallic element, thereby activating the heater. When the heat generated thereby reaches a level causing the bimetallic element to bend, it releases the plunger which then returns to its normal inactive position. Formed in the plunger and the knob is a central duct extending from the heater element to an end opening in the knob. Receivable in the duct is a replaceable tubular cartridge having a heat-responsive, aroma-producing member therein which is activated by the heat to exude an aromatic vapor into the interior of the vehicle.
