  • Publication number: 20230123679
    Abstract: A non-nicotine pod assembly for a non-nicotine e-vaping device may include a first section and a second section connected to the first section. The first section may define a pod outlet and be configured to hold a non-nicotine pre-vapor formulation. The second section may define a pod inlet and be configured to heat the non-nicotine pre-vapor formulation. The pod inlet is in fluidic communication with the pod outlet via a flow path. The flow path may include a first diverged portion, a second diverged portion, and a converged portion. A non-nicotine e-vaping device may include a device body defining a through hole configured to receive the non-nicotine pod assembly such that a pod inlet for the air flow is exposed when the non-nicotine pod assembly is seated within the through hole.

  • Publication number: 20230085955
    Abstract: A non-combustible aerosol-generating device includes a memory storing computer-readable instructions and a controller. The controller is configured to execute the computer-readable instructions to cause the non-combustible aerosol-generating device to: apply power to a heater to preheat an aerosol-forming substrate; determine whether a preheat monitor timer has exceeded a preheat timer threshold; determine whether the aerosol-forming substrate has been previously heated based on a comparison between a first threshold power level and an applied power to the heater in response to the preheat monitor timer having not exceeded the preheat timer threshold; and determine whether the aerosol-forming substrate has been previously heated based on a comparison between a second threshold power level and the applied power to the heater in response to the preheat monitor timer having exceeded the preheat timer threshold.
