Nicotine electronic vaping devices having nicotine pre-vapor formulation level detection and auto shutdown

A nicotine electronic vaping device comprising:

• a nicotine pod assembly including
• a nicotine reservoir to hold nicotine pre-vapor formulation,
• a heater configured to vaporize nicotine pre-vapor formulation drawn from the nicotine reservoir, and
• a memory storing a nicotine pre-vapor formulation vaporization parameter and an aggregate amount of nicotine pre-vapor formulation drawn from the nicotine reservoir;
• and
• a device assembly configured to engage with the nicotine pod assembly, the device assembly including a controller configured to
• estimate an amount of nicotine pre-vapor formulation drawn from the nicotine reservoir during a puff event based on the nicotine pre-vapor formulation vaporization parameter and an aggregate amount of power applied to the heater during the puff event,
• determine an updated aggregate amount of nicotine pre-vapor formulation drawn from the nicotine reservoir based on the aggregate amount of nicotine pre-vapor formulation drawn from the nicotine reservoir stored in the memory and the amount of nicotine pre-vapor formulation drawn from the nicotine reservoir during the puff event,
• determine that the updated aggregate amount of nicotine pre-vapor formulation drawn from the nicotine reservoir is greater than or equal to at least one nicotine pre-vapor formulation level threshold, and
• control the nicotine electronic vaping device to output an indication of a current level of the nicotine pre-vapor formulation in the nicotine reservoir in response to determining that the updated aggregate amount of nicotine pre-vapor formulation drawn from the nicotine reservoir is greater than or equal to the at least one nicotine pre-vapor formulation level threshold.

A method of controlling an nicotine electronic vaping device including a nicotine reservoir to hold nicotine pre-vapor formulation and a heater configured to vaporize nicotine pre-vapor formulation drawn from the nicotine reservoir, the method comprising:

• estimating an amount of nicotine pre-vapor formulation vaporized by the heater during a puff event based on a nicotine pre-vapor formulation vaporization parameter and an aggregate amount of power applied to the heater during the puff event;
• determining an updated aggregate amount of vaporized nicotine pre-vapor formulation based on an aggregate amount of vaporized nicotine pre-vapor formulation stored in a memory and the amount of nicotine pre-vapor formulation vaporized during the puff event;
• determining that the updated aggregate amount of vaporized nicotine pre-vapor formulation is greater than or equal to at least one nicotine pre-vapor formulation level threshold;
• and
• outputting an indication of a current level of the nicotine pre-vapor formulation in the nicotine reservoir in response to determining that the updated aggregate amount of vaporized nicotine pre-vapor formulation is greater than or equal to the at least one nicotine pre-vapor formulation level threshold.
