AI Technical Summary

Technical Problem

In existing heated non-combustible aerosol products, the preparation of the plug material is inconvenient, and it is difficult to release compounds under non-combustible conditions to replace combustible tobacco products. Furthermore, traditional polymer materials are inconvenient to prepare and use.

Method used

The plug is formed by solidifying a slurry precursor within a matrix. The porous body is composed of a framework material, organic liquid additives, and water, with a porosity between 40% and 75%. It can generate volatile components when heated, which are mixed in the aerosol to enhance or change the aerosol properties. The matrix and the porous body are bonded together. The matrix is ​​resistant to high temperatures and does not contain synthetic polymers.

Benefits of technology

It enables convenient preparation and effective heating of the plug, improves or changes aerosol properties, cleans the residue on the heater surface, provides uniform heating and rapid airflow, and enhances the aerosol generation effect.

Abstract

An aerosol-generating article, an aerosol-generating system and a plug for an aerosol-generating article are presented; wherein the aerosol-generating article comprises an outer wrapper and, within the outer wrapper, axially arranged: an aerosol-generating substrate; a plug arranged upstream of the aerosol-generating substrate; the plug comprising: a substantially tubular base and a porous body within the tubular base; the porous body being formed by curing a slurry precursor within the base and bonded to an inner surface of the base; in use, air flows through the plug downstream into the aerosol-generating substrate. With the above aerosol-generating article, the plug is formed by curing a slurry within a tubular base, which is more convenient to manufacture.
