AI Technical Summary

Technical Problem

Existing cylindrical aerosol-generating products suffer from insufficient heating of the aerosol-forming matrix during use, leading to increased manufacturing and transportation costs, as well as increased complexity in component alignment.

Method used

Design an asymmetric aerosol-generated article with a matrix cavity located closer to the distal end, and a length and width greater than its thickness. Employ an external heater with a large contact area, manufacture it through a continuous manufacturing process, and design the airflow pathway to optimize heating efficiency and structural integrity.

Benefits of technology

This method ensures that most of the aerosol-forming matrix is ​​fully heated during use, reducing manufacturing costs, improving heating efficiency and ease of post-use handling, while maintaining the structural integrity of the product.

Abstract

An aerosol-generating article having non-identical inlets and outlets provides an aerosol-generating article for use with an aerosol-generating device to generate an aerosol. The aerosol-generating article has a length extending in an x-direction between a distal end and a proximal end, a width extending in a y-direction between a left side and a right side, and a thickness extending in a z-direction between an upper side and a lower side. The length and the width are greater in magnitude than the thickness. The aerosol-generating article includes an upper surface, a lower surface, and a substrate cavity between the upper surface and the lower surface. A first airflow pathway extends between the distal end of the article and the cavity. A second airflow pathway extends between the cavity and the proximal end of the article. The length of the second airflow pathway is greater than the length of the first airflow pathway. A minimum cross-sectional area of the first airflow pathway is less than a minimum cross-sectional area of the second airflow pathway. The first airflow pathway can be an air inlet, and the second airflow pathway can be an air outlet.
