Heat-not-burn smoking device
A heat-not-burn device includes a heating assembly ( 300 ) having a battery ( 211 ) in a housing ( 201 ), with the battery ( 211 ) electrically connected to an electronic controller ( 212 ) and to a puff sensor ( 205 ) or a switch ( 206 ). The housing ( 201 ) has a receptacle ( 221 ) for receiving a smoking article ( 100 ). A plurality of induction coils ( 222 ) are electrically connected to the electronic controller ( 212 ), with the induction coils ( 222 ) longitudinally spaced apart along the receptacle ( 221 ). The smoking article ( 100 ) has a plurality of spaced apart conductive elements or plates ( 124 ) with smoking material ( 125 ), such as tobacco, between adjacent conductive elements or plates ( 124 ).
1. A vapor generator, comprising:
a battery unit including a battery in a battery housing, and a plurality of longitudinally spaced apart induction coils around a receptacle in the housing, the induction coils electrically connected to the battery;
a vapor article configured to be inserted into the receptacle, the vapor article including a non-conductive cylindrical article housing containing a plurality of spaced apart conductive round flat plates; the plates parallel to each other and perpendicular to a longitudinal axis of the housing; the plates in contact with an interior surface of the housing to form a plurality of compartments in the housing, the compartments containing a vapor medium; each plate having a through passage to allow air flow through the housing; and
a seal at a first end of the receptacle, the seal engaging the vapor article.
2. The vapor generator of claim 1 further including a control circuit in the battery housing configured to separately control each of the induction coils.
3. The vapor generator of claim 1 wherein each induction coil is longitudinally aligned with one of the plates.
4. A vapor generator, comprising:
a battery unit including a battery in a battery housing, and a plurality of longitudinally spaced apart induction coils around a receptacle in the housing, the induction coils electrically connected to the battery;
a vapor article configured to be inserted into the receptacle, the vapor article including a non-conductive cylindrical article housing containing a plurality of spaced apart conductive round flat plates; the plates parallel to each other and perpendicular to a longitudinal axis of the housing; the plates in contact with an interior surface of the housing to form a plurality of compartments in the housing, the compartments containing a vapor medium; each plate having a through passage to allow air flow through the housing; and
a mouthpiece on the vapor article projecting out of the receptacle when the vapor article is inserted into the receptacle.
5. The vapor generator of claim 4 further including a control circuit in the battery housing configured to separately control each of the induction coils.
6. The vapor generator of claim 4 wherein each induction coil is longitudinally aligned with one of the plates.
7. A vapor generator, comprising:
a battery unit including a battery in a battery housing, and a plurality of longitudinally spaced apart induction coils around a receptacle in the housing, the induction coils electrically connected to the battery;
a vapor article configured to be inserted into the receptacle, the vapor article including a non-conductive cylindrical article housing containing a plurality of spaced apart conductive round flat plates; the plates parallel to each other and perpendicular to a longitudinal axis of the housing; the plates in contact with an interior surface of the housing to form a plurality of compartments in the housing, the compartments containing a vapor medium; each plate having a through passage to allow air flow through the housing; and
a filter on an end of the vapor article projecting out of the receptacle when the vapor article is inserted into the receptacle.
8. The vapor generator of claim 7 further including a control circuit in the battery housing configured to separately control each of the induction coils.
9. The vapor generator of claim 7 wherein each induction coil is longitudinally aligned with one of the plates.
