Abstract

A vaping system includes: (a) a disposable vaping device that includes the following non user-replaceable items: (i) a heating element; (ii) a rechargeable battery, and (iii) a liquid reservoir that provides liquid to the heating element; and (b) an automatic liquid filling device, including (i) a first aperture or port configured to receive a liquid bottle or container containing atomisable liquid; (ii) a second aperture or port configured to receive the vaping device; (iii) an electronic liquid level sensing sub-system; (iv) a liquid filling sub-system configured to pump liquid from the liquid bottle or container to the liquid reservoir in the vaping device and (v) a battery charging sub-system.

Claims27

Dependent claims

A vaping device including a heating element, a power source, a pulse width modulated (PWM) system to deliver power from the power source to the heating element, and a microcontroller or chip configured with an inner closed loop temperature control algorithm configured to regulate a duty cycle of the PWM system to reach a setpoint temperature;

and in which the microcontroller or chip is also configured with a second, outer closed loop power control algorithm with a power setpoint, and is configured to measure or infer power delivered to the heating element, and to automatically modify the setpoint temperature used by the inner control loop depending on the variation of the measured or inferred power from the power setpoint;
and in which the microcontroller or chip is configured so that the measured or inferred power is an average power calculated by using the instantaneous V and I generated by a system microcontroller unit (MCU) for one or more timeslots during which power is delivered.

Dependencies are inferred from the claim text.
