AI Technical Summary

⚠Technical Problem

Existing heat-not-burn aerosol-generating products are insufficient in maintaining low draw resistance, especially when aerosol forming agents are added to tobacco or non-tobacco materials, the resulting products have high draw resistance.

⚗Method used

A continuous slurry precursor is wound to form an aerosol generation matrix. The matrix unit has a specific shape and air channel structure, including first and second air channels and a slit design, forming a porous structure to reduce suction resistance.

🎯Benefits of technology

By optimizing the structural design of the aerosol generation matrix, the absorption resistance was significantly reduced, improving the ease of use and efficiency of aerosol-generated products.

Abstract

The present application provides an aerosol-generating article, a preparation method, and an aerosol-generating system. The aerosol-generating article comprises an aerosol-generating substrate configured to be cylindrical and arranged in the axial direction of the aerosol-generating article. The aerosol-generating substrate comprises a plurality of substrate units arranged in the circumferential direction, and the substrate units are configured to generate an aerosol when heated. In the aerosol-generating article described above, the aerosol-generating substrate is composed of a plurality of circumferentially arranged substrate units, which is advantageous for reducing draw resistance.
