  • Publication number: 20240365862
    Abstract: A cartridge for a vapour generating device includes a liquid store for containing a vapour generating liquid and a vaporization device including a heating element including a substantially cylindrical inductively heatable susceptor positioned beneath the liquid store and arranged coaxially with respect to a central longitudinal axis of the cartridge. The cartridge includes at least one channel or opening which connects the liquid store to the vaporization device and a porous liquid transfer element positioned adjacent to the channel or opening and arranged to hold and transfer vapour generating liquid from the liquid store to the vaporization device. The inductively heatable susceptor is arranged in thermal proximity to the porous liquid transfer element to heat and vaporize the vapour generating liquid.

  • Publication number: 20240122252
    Abstract: A method for controlling the heating of a susceptor of an aerosol-generating device is described, the susceptor being inductively heated by an oscillating circuit driven by an inverter at an operating frequency. The method includes a power delivery mode of the aerosol-generating device, a step of updating the operating frequency being performed during the power delivery mode and including the following sub-steps: determining, using a controller, the resonant frequency of the oscillating circuit during heat of the susceptor; and setting, using the controller, the operating frequency at the determined resonant frequency. The updating step is continuously repeated during power delivery mode of the aerosol-generating device.

  • Publication number: 20240114973
    Abstract: A method for controlling the heating of a susceptor of an aerosol-generating device is described, the susceptor being inductively heated by an oscillating circuit driven by an inverter, an optional boost converter being connected between a power supply unit and the inverter, the boost converter and being configured to step-up voltage from an input voltage supplied from the power supply unit to an output voltage delivered to the inverter. The method includes a power delivery mode of the aerosol-generating device and a temperature identification mode of the aerosol-generating device in which the amount of power supplied to the inverter is lower than the amount of power supplied during the power delivery mode. The method includes determining the temperature of the susceptor, e.g. based on a determined resonant frequency or resonant capacitor voltage of the oscillating circuit.
