AI Technical Summary

Technical Problem

Dielectric heating aerosol generators face challenges in maintaining moisture levels in aerosol-generating materials, leading to decreased heating efficiency and inconsistent aerosol quality due to moisture evaporation, which can result in a burnt taste and reduced performance.

Method used

An aerosol generating device with a control unit that adjusts power supply to a source unit, including stages of power reduction and rupture of a capsule within the aerosol generating article using electromagnetic waves, ensuring adequate moisture content and improved aerosol production.

Benefits of technology

The device effectively maintains moisture levels, enhancing vapor production and improving aerosol taste by controlling power supply to rupture the capsule at appropriate times, thereby stabilizing aerosol generation performance.

Abstract

An aerosol generating device according to an embodiment may comprise: a housing including an accommodation space for accommodating at least a portion of an aerosol generating article; a source unit located inside the housing and configured to generate electromagnetic waves; a radiation unit for heating the aerosol generating article by radiating, in a direction toward the aerosol generating article, the electromagnetic waves generated by the source unit inside the housing; and a power source for supplying power to the source unit, wherein the power source is controlled to supply first power to the source unit such that a capsule included in the aerosol generating article is ruptured by the electromagnetic waves generated from the source unit, and then to supply second power smaller than the first power to the source unit.
