AI Technical Summary

Technical Problem

How to further reduce the content of unplanned substances in the aerosol produced by heated cigarettes, and improve oral comfort and aroma richness.

Method used

An aerosol generation device is used, combined with a heater and a catalytic light source. The catalytic light source provides catalytic light during the heating process to degrade unplanned substances in the aerosol generation matrix. The catalytic light source includes LED beads and a laser with a wavelength range of 300-450nm and a luminous power of 1W-3W. The controller synchronously controls the heating and the supply of the light source.

Benefits of technology

It significantly reduces the content of harmful components such as formaldehyde, crotonaldehyde, and benzo[a]pyrene in aerosols, improves the smoking experience, and does not affect the sensory quality of the smoke.
