Solution Overview

Problem

Existing aerosol provision devices face challenges in effectively heating aerosol generating materials without burning them, requiring a heater component design that efficiently transfers heat while maintaining control over the temperature and volume of the aerosol produced.

Innovation Solution

A heater component with a specific length-to-aerosol generating material length ratio between 1.03 and 1.25, combined with a coil for heating, ensures efficient heat transfer and temperature control, using materials like carbon steel or alloys with high iron content for effective heating, and a thin wall thickness for rapid heating.
