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.
