Abstract
A cartridge for a personal vaporizing device includes a liquid store, a liquid transfer element, a heating element, a first power terminal and a second power terminal connected to the heating element, and a memory configured to store a first reference value indicating the resistance of the heating element at a reference temperature or reference. A method of manufacturing such a cartridge is also provided. A main body of a personal vaporizing device has a cartridge seating configured to receive such a cartridge.
Claims18
A cartridge for a personal vaporizing device, the cartridge comprising:
- a liquid store,
- a liquid transfer element,
- a heating element,
- a first power terminal and a second power terminal connected to the heating element, and
- a memory storing a first reference value indicating resistance of the heating element at a reference temperature or a reference temperature range of the heating element,
- wherein the memory stores a second reference value indicating resistance of an open loop of an electronic circuit, the open loop extending between the first and second power terminals and including the heating element.
A main body of a personal vaporizing device, the main body having a cartridge seating configured to receive a cartridge comprising:
- a heating element,
- a first power terminal and a second power terminal connected to the heating element to thereby form an open loop between the first and second power terminals, which form endpoints of the open loop, and including the heating element connected between the first and second power terminals;
- wherein the cartridge seating comprises:
- a first pair of electrical connectors configured to establish an electrical circuit when connected to respective ones of the first and second power terminals of the cartridge whereby power may be supplied to the heating element from the main body via the first pair of electrical connectors and the first and second power terminals, and
- a second pair of electrical connectors configured to establish a measuring circuit when connected to respective ones of the first and second power terminals for measuring voltage between the first and second power terminals of the cartridge whilst power is supplied to the first and second power terminals via the first pair of electrical connectors.
