Embodiment Construction

[0040] figure 1 Emitter 2 and sensor 4 are shown. The emitter emits light 6 in the direction of the sensor 4 . The emitted light 6 is directed towards the aerosol chamber 8 .

[0041] In the aerosol chamber 8, a component 10 comprising an aerosol-forming substrate is included. Component 10 in figure 1 is depicted as a vaporized component with multiple small particles. Expressed as figure 1 .1 of figure 1 The left part of the aerosol chamber 8 with a small amount of component 10 in the aerosol chamber 8 is shown. Thus, the light emitted by the emitter 2 and directed towards the aerosol chamber 8 is only partially absorbed by the component 10 .

[0042] In more detail, the component 10 is capable of at least partially absorbing the light emitted by the emitter 2 . In this respect, the emitter 2 emits light having one or more specific wavelengths, and the component at least partially absorbs this light. Thus, depending on the amount of components present in the aerosol c...

Abstract

The invention relates to a hand-held aerosol generating device. The handheld aerosol generating device comprises an emitter (2) configured to emit light. Furthermore, the handheld aerosol generating device comprises a sensor (4) configured to receive light, and an aerosol chamber (8) configured to contain an aerosol. The emitter is also configured to emit light into the aerosol chamber. The sensor is also configured to receive light from the aerosol chamber and measure at least one wavelength of a spectrum of the received light.

Description

technical field [0001] The invention relates to an aerosol generating system comprising a transmitter and a receiver for electromagnetic radiation and an aerosol chamber for containing the aerosol to be analyzed. Background technique [0002] Hand-held electrically operated aerosol generating systems are well known and consist of a device part comprising batteries and control electronics and a separate cartridge comprising a liquid aerosol-forming substrate contained in a liquid storage part. Supply and electrically operate vaporizer or heater elements. The quality of the aerosol generated may vary for each device. Also, the quality of the generated aerosol may depend on the liquid aerosol-forming substrate used, as different liquid aerosol-forming substrates may be used, eg with different fragrance components. Furthermore, the performance of an aerosol generating system can change over time. The quality of the aerosol generated may also depend on the strength of the puff...
