Smoking articles

Abstract

Smoking articles are disclosed herein. In one aspect, a smoking article includes a heat source configured to generate heat upon ignition thereof, a first substrate material having an aerosol precursor composition associated therewith and a first end being fixedly engaged with the heat source, and an aerosol delivery component having opposed first and second ends, the first end of the aerosol delivery component being engaged with the second end of the first substrate material. In some aspects, the aerosol delivery component includes a second substrate material having the aerosol precursor composition associated therewith and being disposed about the first end of the aerosol delivery component and a tobacco material disposed between the second substrate material and the mouthpiece, the aerosol precursor composition associated with the first and second substrate materials being configured to produce an aerosol in response to the heat generated by the ignited heat source.

That which is claimed: 
     
         1 . A smoking article comprising:
 a power source;   a heat source in communication with the power source, the heat source being configured to generate heat in response to power received from the power source;   a tubular casing extending axially about the heat source;   a tobacco material housed within the tubular casing, the tobacco material being configured in a cylindrical shape extending about a surface of the heat source, between the heat source and the tubular casing, the tobacco material being configured to produce an aerosol in response to the heat generated by the heat source; and   a mouthpiece defined by an end of the tubular casing, the mouthpiece being configured to receive the aerosol from the solid tobacco material in response to a draw applied to the mouthpiece.   
     
     
         2 . The smoking article of  claim 1 , further comprising a filter material within the mouthpiece. 
     
     
         3 . The smoking article of  claim 1 , wherein the filter material comprises cellulose acetate. 
     
     
         4 . The smoking article of  claim 1 , wherein the power source comprises a lithium-ion battery. 
     
     
         5 . The smoking article of  claim 1 , wherein the form of the heat source comprises a strip. 
     
     
         6 . The smoking article of  claim 1 , wherein the heat source is a cylindrical rod electrically connected to the power source. 
     
     
         7 . The smoking article of  claim 1 , wherein the power source is housed in a tubular control enclosure, the tubular enclosure being engaged with the tubular casing. 
     
     
         8 . The smoking article of  claim 1 , further comprising a control unit in communication with the power source, the control unit being configured to actuate the power produced by the power source and to direct the power to the heat source. 
     
     
         9 . The smoking article of  claim 8 , further comprising a pushbutton in communication with the control unit, the pushbutton being configured to control actuation of the power produced by the power source. 
     
     
         10 . The smoking article of  claim 1 , wherein the tubular casing comprises an insulating material. 
     
     
         11 . The smoking article of  claim 8 , wherein the insulating material comprises graphite or graphene. 
     
     
         12 . The smoking article of  claim 1 , wherein the tobacco material comprises one or more of tobacco-containing beads, tobacco shreds, tobacco strips, pieces of a reconstituted tobacco material, or any combinations thereof. 
     
     
         13 . The smoking article of  claim 1 , wherein the power source comprises an electrical power source. 
     
     
         14 . The smoking article of  claim 1 , wherein the power source comprises a rechargeable battery. 
     
     
         15 . The smoking article of  claim 1 , wherein the power source comprises one or more capacitors. 
     
     
         16 . The smoking article of  claim 1 , wherein the heat source is configured to generate inductive heat. 
     
     
         17 . The smoking article of  claim 1 , wherein the heat source is configured to generate conductive heat. 
     
     
         18 . The smoking article of  claim 17 , wherein the heat source is configured to generate radiative heat. 
     
     
         19 . The smoking article of  claim 1 , further comprising a control device configured to be responsive to a draw applied to the article. 
     
     
         20 . The smoking article of  claim 1 , wherein the control unit further comprises a current regulating component.
