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 aerosol generating smoking article comprising:
a mouthpiece configured to allow for draw of air through at least a portion of the aerosol generating smoking article;
an electrical resistance heater configured for electrical connection with an electrical power source;
an aerosol-generating material;
a substrate carrier operatively positioned such that the aerosol-generating material can be wicked into contact with the electrical resistance heater for volatilization to produce an aerosol; and
one or more control components configured to detect the draw of air through at least a portion of the aerosol generating smoking article and control passage of an electrical current from the electrical power source to the electrical resistance heater based on a property of the draw of air such that operation of the electrical resistance heater varies based on the property of the draw of air.
2. The aerosol generating smoking article of claim 1 , wherein the one or more control components includes a sensor.
3. The aerosol generating smoking article of claim 1 , wherein the one or more control components includes a threshold detector.
4. The aerosol generating smoking article of claim 1 , wherein the one or more control components is configured to control passage of the electrical current from the electrical power source to the electrical resistance heater such that heat generation by the electrical resistance heater is substantially proportional to a period of the draw of air.
5. The aerosol generating smoking article of claim 1 , wherein the one or more control components is configured to control passage of the electrical current from the electrical power source to the electrical resistance heater such that heat generation by the electrical resistance heater is substantially proportional to a magnitude of the draw of air.
6. The aerosol generating smoking article of claim 1 , wherein the one or more control components is configured to control passage of the electrical current from the electrical power source to the electrical resistance heater such that heat generation by the electrical resistance heater is substantially proportional to both of a period and a magnitude of the draw of air.
7. The aerosol generating smoking article of claim 1 , wherein the one or more control components is configured to sense a strength of the draw of air through at least a portion of the aerosol generating smoking article.
8. The aerosol generating smoking article of claim 7 , wherein the one or more control components is configured to control an amount of the electrical current that is supplied to the electrical resistance heater so as to substantially correspond to the strength of the draw of air.
9. The aerosol generating smoking article of claim 1 , wherein the aerosol-generating material comprises glycerin, propylene glycol, or a mixture thereof.
10. The aerosol generating smoking article of claim 1 , wherein the aerosol-generating material comprises one or more components derived from tobacco.
11. The aerosol generating smoking article of claim 1 , wherein the aerosol generating smoking article further includes tobacco.
12. The aerosol generating smoking article of claim 1 , wherein the aerosol-generating material is incorporated within a cartridge.
13. The aerosol generating smoking article of claim 12 , wherein the cartridge is formed at least partially of a plastic material.
14. The aerosol generating smoking article of claim 1 , wherein the one or more control components is configured to deliver current controlled by a timer to produce a quantity of heat from the electrical resistance heater for a timed period and is further configured to control passage of the electrical current from the electrical power source to the electrical resistance heater such that heat generation by the electrical resistance heater is substantially proportional to a remaining period of the draw of air.
