ABSTRACT:
A deodorizing cigarette lighter is disclosed for use in a motor vehicle. A cigarette igniting unit having a standard conventional structure is used to store a heat responsive, nonflammable deodorizing agent that emits a fragrant vapor into the vehicle interior upon energization of an electric heating element associated with the lighter. The cigarette lighter includes a tubular plug body having a chamber formed therein that is used to retain the deodorizing agent. A slotted cap is attached to one end of the plug body, and a knob is attached to the cap. The lighter also includes a contact cup at the other end of the plug body that houses the heating coil. One end of the heating element is maintained in thermal communication with the contact cup, and the other end of the heating element is connected to a thermally conductive rivet. The rivet is maintained in a heat transfer relationship with the plug body. The deodorizing agent emits a fragrant vapor upon energization of the heating element. Passages exist between the plug body and cap which allow for vapors to exude from the chamber. Vapors then can flow through a vented friction sleeve slidably carried on the plug body after the heating element is heated to a red glow. The lighter also includes an ashguard that is telescopically engaged with the vented friction sleeve. The ashguard has stop means formed therein which restricts outward axial retraction of the friction sleeve after the heating coil is energized.
