Abstract

An electrical smoking system includes a lighter having a plurality of electrical heater elements and a system for electrically actuating the heater elements. The lighter is adapted to receive a cigarette with the heater elements at least partially superposing a portion of the cigarette. The lighter further includes an electromagnet arranged in proximity to magnetic portions of the heater elements, with the electromagnet being actuable to selectively repulse or attract the heater elements.

Claims (25)

1. An electrical smoking system comprising:

a lighter comprising at least one electrical heater element and a system for electrically actuating said at least one heater element, said lighter adapted to at least partially receive a cigarette with said at least one heater element at least partially superposing a portion of the cigarette,

at least a portion of said at least one heater element being magnetic, and

said lighter further including an electromagnet arranged in proximity to said magnetic portion of said at least one heater element, said electromagnet being actuable to selectively repulse or attract said heater element,

said magnetic portion of said at least one heater element comprises a permanent magnet attached near a distal end of said at least one heater element, like poles of said permanent magnet and said electromagnet are positioned facing each other such that actuation of said electromagnet generates a repulsive force between said electromagnet and said at least one heater element.

2. The electrical smoking system according to claim 1 , wherein:

repulsion of said at least one heater element by actuation of said electromagnet moves said at least one heater element into close contact with a cigarette positioned in said lighter.

3. The electrical smoking system according to claim 2 , wherein:

said electromagnet is actuated in response to a signal generated by positioning of a cigarette within said lighter.

4. The electrical smoking system according to claim 2 , wherein:

said electromagnet is actuated in response to a signal generated by a smoker puffing on a cigarette positioned within said lighter.

5. An electrical smoking system comprising:

a lighter comprising at least one electrical heater element and a system for electrically actuating said at least one heater element, said lighter adapted to at least partially receive a cigarette with said at least one heater element at least partially superposing a portion of the cigarette,

at least a portion of said at least one heater element being magnetic, and

said lighter further including an electromagnet arranged in proximity to said magnetic portion of said at least one heater element, said electromagnet being actuable to selectively repulse or attract said heater element,

said lighter comprises a plurality of said at least one electrical heater element adapted to superpose a portion of the cigarette in circumferentially spaced relation, and wherein

said at least a portion of each of said electrical heater elements comprises a permanent magnet attached near a distal end of each of said electrical heater elements.

6. The electrical smoking system according to claim 5 , wherein:

like poles of said permanent magnets and said electromagnet are positioned facing each other such that actuation of said electromagnet generates a repulsive force between said electromagnet and said heater elements.

7. The electrical smoking system according to claim 6 , wherein:

repulsion of said heater elements by actuation of said electromagnet moves said heater elements into close contact with a cigarette positioned in said lighter.

8. The electrical smoking system according to claim 7 , wherein:

said electromagnet is actuated in response to a signal generated by positioning of a cigarette within said lighter.

9. The electrical smoking system according to claim 7 , wherein:

said electromagnet is actuated in response to a signal generated by a puff detector.
