Patent number: 11974599Abstract: 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.Type: GrantFiled: March 5, 2021Date of Patent: May 7, 2024Assignee: PHILIP MORRIS USA INC.Inventors: Michel Thorens, Jean-Marc Flick, Olivier Yves Cochand
