Patent number: 9420829Abstract: A smoking system includes a capillary wick for holding liquid, at least one air inlet, at least one air outlet and a chamber between the air inlet and air outlet. The air inlet, the air outlet and the chamber are arranged so as to define an air flow route from the air inlet to the air outlet via the capillary wick so as to convey aerosol formed from the liquid to the air outlet. The smoking system further includes at least one guide for channeling the air flow in the air flow route, so as to control particle size in the aerosol. The smoking system optionally includes at least one heater for heating the liquid in at least a portion of the capillary wick to form the aerosol.Type: GrantFiled: October 27, 2010Date of Patent: August 23, 2016Assignee: Philip Morris USA Inc.Inventors: Michel Thorens, Jean-Marc Flick, Olivier Yves Cochand, Flavien Dubief

Publication number: 20160135507Abstract: 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: ApplicationFiled: January 20, 2016Publication date: May 19, 2016Inventors: Michel THORENS, Jean-Marc FLICK, Olivier Yves COCHAND

Publication number: 20130340750Abstract: There is provided a method for controlling at least one electric heating element of an electrically heated aerosol generating system for heating an aerosol-forming substrate. The electrically heated aerosol generating system has a sensor for detecting airflow indicative of a user taking a puff having an airflow duration. The method includes the steps of: increasing the heating power for the at least one heating element from zero to power p1 when the sensor detects that the airflow rate has increased to a first threshold, maintaining the heating power at a power p1 for at least some of the airflow duration, and decreasing the heating power for the at least one heating element from power p1 to zero when the sensor detects that the airflow rate has decreased to a second threshold.Type: ApplicationFiled: December 2, 2011Publication date: December 26, 2013Applicant: Philip Morris Products S.A.Inventors: Michel Thorens, Jean-Marc Flick, Olivier Yves Cochand, Flavien Dubief
