Abstract
An aerosol-generating system includes a liquid-storage portion configured to hold a liquid aerosol-forming substrate, a first electrode, a second electrode, and a control system. The second electrode is spaced from the first electrode. At least a portion of the liquid storage portion is arranged between the first electrode and the second electrode. The control system is configured to measure an electrical quantity between the first electrode and the second electrode, and detect a draw on the aerosol-generating system based on the measured electrical quantity information.
Claims21
An aerosol-generating system comprising:
- a storage portion configured to hold an aerosol-forming substrate;
- a first electrode;
- a second electrode spaced from the first electrode, a portion of the storage portion being arranged between the first electrode and the second electrode;
- and
- a control system configured to,
- measure an electrical quantity of the portion of the storage portion between the first electrode and the second electrode,
- determine a rate of change of the measured electrical quantity of the portion of the storage portion, and
- detect a draw on the aerosol-generating system based on the rate of change of the measured electrical quantity of the portion of the storage portion.
A main unit for an aerosol-generating system comprising:
- least one of a first electrode and a second electrode;
- and
- a control system configured to:
- measure an electrical quantity of a storage portion between the first electrode and the second electrode, the storage portion configured to store an aerosol-forming substrate,
- determining a rate a change of the measured electrical quantity of the storage portion, and
- detect a draw on the aerosol-generating system based on the rate of change of the measured electrical quantity of the storage portion.
A method of detecting a draw on an aerosol-generating system, the method comprising:
- measuring an electrical quantity or a portion of a storage portion between a first electrode and a second electrode, the portion of the storage portion configured to store an aerosol-forming substrate between the first electrode and the second electrode;
- determining a rate of change of the measured electrical quantity of the portion of the storage portion;
- and
- detecting a draw on the aerosol-generating system based on the rate of change of the measured electrical quantity of the portion of the storage portion.
