Electronic smoking article

Abstract

An electronic smoking article includes a heater in communication with a liquid supply reservoir including liquid material and operable to heat the liquid material to a temperature sufficient to volatilize the liquid material contained therein and form an aerosol. The volatilized material flows through a sheath flow and aerosol promoter insert that is operable to cool the aerosol, reduce the particle size of the aerosol and increase the delivery rate of the aerosol.

We claim: 
     
         1 . An electronic smoking article comprising:
 a sheath flow and aerosol promoter (SFAP) insert operable to produce a sheath airflow within the electronic smoking article and operable to direct an aerosol through a constriction, whereby aerosol formation is enhanced and losses due to condensation within the electronic smoking article are abated.
