Title:
AEROSOL-GENERATING ARTICLE, PREPARATION METHOD, AND INSPECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/123772
Kind Code:
A1
Abstract:
An aerosol-generating article for use with an electrically heated aerosol-generating device, a preparation method, and an inspection method. Wherein, the aerosol-generating article comprises a smoke generation section (1) containing a smoke generation material (2) therein. The electrically heated aerosol-generating device comprises a heating element (3) which can be inserted into the smoke generation section (1). The maximum heat conducting area thermal resistance δ/λe of the smoke generation section (1) meets the condition: 0.01 <δ/λe < 0.06, where δ represents the maximum radial distance by which the smoke generation section (1) is heated and the unit is m, and λe represents an effective thermal conductivity coefficient of the smoke generation section (1) and the unit is W/m·K. The aerosol-generating article exhibits good heat transfer performance and high heating efficiency.
