Tobacco-containing smoking article
A smoking article may include a cigarette incorporated within an electrically powered aerosol generating device that acts as a holder for that cigarette. The smoking article possesses at least one form of tobacco. The smoking article also possesses a mouth-end piece that is used by the smoker to inhale components of tobacco that are generated by the action of heat upon components of the cigarette. A representative smoking article possesses an outer housing incorporating a source of electrical power (e.g., a battery), a sensing mechanism for powering the device at least during periods of draw, and a heating device (e.g., at least one electrical resistance heating element) for forming a thermally generated aerosol that incorporates components of tobacco. During use, the cigarette is positioned within the device, and after use, the used cigarette is removed from the device and replaced with another cigarette.
1 . An electrically-powered, aerosol-generating smoking article comprising:
a housing;
an electrical power source within the housing;
a cartridge inserted into the housing, the cartridge including a liquid and electrical resistance heating powered by the electrical power source for heating the liquid to generate an aerosol, wherein the cartridge includes an air path arranged such that the aerosol is directed to exit the cartridge at a mouth end, a portion of the airpath being adjacent a resistive heating element; and
an air passageway between the housing and the cartridge for air drawn into the smoking article.
2 . The smoking article of claim 1 , further comprising a mouthpiece attached proximate the mouth end of the cartridge.
3 . The smoking article of claim 2 , wherein the air drawn into the smoking article through the air passageway is air from outside of the smoking article.
4 . The smoking article of claim 3 , wherein the aerosol includes at least a portion of the air drawn through the air passageway.
5 . The smoking article of claim 4 , wherein a visible mainstream aerosol flows out the mouthpiece into a mouth of a user of the smoking article.
6 . The smoking article of claim 2 , wherein the mouthpiece is secured by a friction fit at the cartridge.
7 . The smoking article of claim 2 , wherein the air path through the cartridge comprises aerosol flowing to the mouthpiece.
8 . The smoking article of claim 1 , wherein the resistive heating element comprises an electrical resistance heater in the cartridge configured to perform the electrical resistance heating.
9 . The smoking article of claim 8 , wherein the liquid can be wicked into contact with the electrical resistance heater and volatilized to generate the aerosol.
10 . The smoking article of claim 9 , wherein the cartridge comprises an absorbent fibrous material absorbing at least a portion of the liquid that is wicked into contact with the electrical resistance heater to be vaporized to generate the aerosol that can be drawn into a mouth of the user of the smoking article.
11 . The smoking article of claim 8 , further comprising a puff-actuated controller comprising a sensor adapted to sense draw on the smoking article by a user.
12 . The smoking article of claim 11 , wherein the electrical resistance heater is powered by the electrical power source in response to the sensor sensing draw on the smoking article.
13 . The smoking article of claim 1 , wherein the air passageway is formed between an inner wall of the housing and an outer wall of the cartridge.
14 . The aerosol-generating article of claim 1 , wherein the liquid comprises glycerin, nicotine, and a flavoring agent.
15 . The smoking article of claim 1 , further comprising storage in the cartridge for the liquid.
16 . The smoking article of claim 1 , wherein a conductor of heat produced by the electrical resistance heating is in the form of wire, foil, tubing, or beads.
