Abstract
A handheld aerosol-generating device may include an emitter configured to emit light, a sensor configured to receive light, and an aerosol chamber configured to hold an aerosol. The emitter may emit light into the aerosol chamber. The sensor may receive light from the aerosol chamber and measure at least one wavelength of the spectrum of the received light. Direct measurement of parameters, and/or the presence, of the aerosol in the aerosol chamber may be enabled, where the direct measurement of parameters of the aerosol in the aerosol chamber may enable optimal operation of an aerosol-generating system that may be the handheld aerosol-generating device.
Claims18
An aerosol-generating device, comprising:
- a main device including control circuitry;
- and
- a cartridge engaged with the main device, at least one of the cartridge and the main device including
- an aerosol chamber,
- an array of at least two emitters arranged outside of the aerosol chamber, and
- an array of at least two sensors arranged outside of the aerosol chamber, the array of at least two sensors being arranged opposite the array of at least two emitters,
- wherein the cartridge includes an outlet end, a liquid storage configured to hold a supply of liquid aerosol-forming substrate, and a heating element, the heating element being electrically operated.
A cartridge configured to be engaged with an aerosol-generating device, the cartridge comprising:
- an aerosol chamber;
- an array of at least two emitters arranged outside of the aerosol chamber;
- an array of at least two sensors arranged outside of the aerosol chamber, the array of at least two sensors being arranged opposite the array of at least two emitters,
- an outlet end;
- a liquid storage configured to hold a supply of liquid aerosol-forming substrate;
- and
- a heating element, the heating element being electrically operated.
An aerosol-generating device, comprising:
- a main device including a controller, the controller being configured to actuate an array of at least two emitters arranged outside of an aerosol chamber, and to process signals from an array of at least two sensors arranged outside of the aerosol chamber, the array of at least two sensors being arranged opposite the array of at least two emitters;
- and
- a cartridge engaged with the main device, the aerosol chamber being arranged in one of the main device and the cartridge, the cartridge including an outlet end, a liquid storage configured to hold a supply of liquid aerosol-forming substrate, and a heating element, the heating element being electrically operated.
