ABSTRACT:
The electric cigarette lighter combines the handling advantages of rotating operation with the contacting advantages of pressing operation. A shaft is rotationally fixed to a rotary knob but axially slidable with respect thereto. A heater body affixed to the shaft is brought from an initial position to an operating position through a rotating movement of the rotary knob and a superimposed rotary thrust movement of the shaft. The heater body is automatically returned from the operating position to to the initial position through likewise superimposed rotary thrust spring forces of one or two restoring springs.
