An electrically heated smoking
system includes a shell and a replaceable
mouthpiece. The shell includes an
electric power supply and electric circuitry. The
mouthpiece includes a
liquid storage portion and a capillary wick having a first end and a second end. The first end of the wick extends into the
liquid storage portion for contact with liquid therein. The
mouthpiece also includes a
heating element for heating the second end of the capillary wick, an air outlet, and an
aerosol forming chamber between the second end of the capillary wick and the air outlet. When the shell and mouthpiece are engaged or connected, the
heating element is in
electrical connection with the power supply via the circuitry, and a flowpath for air is defined from at least one air inlet to the air outlet via the
aerosol forming chamber. In use, liquid is transferred from the
liquid storage portion towards the
heating element by
capillary action in the wick. Liquid at the second end of the capillary wick is vaporized by the heating element. The supersaturated vapor created, is mixed and carried in the air flow from the at least one air inlet to the
aerosol forming chamber. In the aerosol forming chamber, the vapor condenses to form an aerosol, which is carried towards the air outlet.
