Electrically heated cigarette smoking system with internal manifolding for puff detection

An electrically heated cigarette smoking system, comprising:

• a housing;
• a plurality of heating elements arranged within said housing adapted to receive there-between a portion of a cigarette;
• a power source connected to the heating elements;
• a bypass flow passage within said housing, said bypass flow passage being in fluid communication with the ambient air surrounding said housing;
• a suction flow passage within said housing and creating a pathway for air to be drawn by a smoker into contact with the cigarette,
• said suction flow passage being connected to said bypass flow passage through a flow diverting passage so that ambient air passing through said bypass flow passage will only flow into said suction flow passage when the smoker draws on the cigarette, and
• a sensor operable to detect air flow in said suction flow passage and output a signal indicative of a smoker drawing on said cigarette.

An electrically heated cigarette smoking system, comprising:

• a housing;
• a plurality of heating elements arranged within said housing adapted to receive there-between a portion of a cigarette;
• a power source that supplies energy to the heating elements for heating the cigarette;
• and
• a manifold arrangement defining a chamber surrounding a portion of the cigarette at a filter section of the cigarette, and said chamber being in fluid communication with an internal portion of the cigarette through openings into said filter section of the cigarette.
