Abstract: A vaporizing device (10) includes a battery unit (12) having a battery (13), an electronic controller (20), and an induction coil (32) on or in a core, such as a ferrite split ring (34) or cup (62) magnetic core. A cartridge (14) holding liquid has at least one heater plate (46, 74) and a liquid conductor (48, 76). The cartridge (14) is attachable to the battery unit (12) with the heater plate (46, 74) adjacent to the core. The heater plate (46,74) heats the liquid conductor (48, 76) to create vapor when high frequency alternating electric current is provided to the induction coil (32). This offers manufacturing and cost advantages.

Abstract: 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).

Abstract: An electronic cigarette includes an atomizer having a coil-less heating element having a heating section, two leads electrically connected to the heating section, and a liquid guiding structure. The liquid guiding structure includes two pads, a first pad and a second pad sandwiching at least a portion of the heating section. A gasket is positioned between a liquid supply and the first pad conducts liquid from the liquid supply to the first pad.
