AI Technical Summary

Technical Problem

Existing aerosol-generating cartridges with a single electric heater often result in inefficient heating of the aerosol-generating substrate, leading to uneven heating, discomfort due to excessive heat transfer, and inconsistent aerosol delivery.

Method used

The cartridge incorporates first and second heating elements positioned within the substrate compartment, allowing for independent control and optimized heating profiles, with the first heating element heating at a higher temperature for initial aerosol delivery and the second for consistent generation throughout the user experience.

Benefits of technology

This configuration enhances heating efficiency, reduces discomfort by minimizing external heat transfer, and ensures consistent aerosol delivery over the duration of use.

Abstract

There is provided a cartridge (10) for use with an aerosol-generating device (800). The cartridge (10) comprises a housing (100) defining an air inlet (110), an air outlet (120), and a substrate compartment (400) between the air inlet (110) and the air outlet (120). The cartridge (10) also comprises an aerosol-generating substrate (300), a first heating element (630; 730), a second heating element (631), and a third heating element (632; 732) each positioned within the substrate compartment (400), wherein the second heating element (631) is positioned between the first heating element (630; 730) and the third heating element (632; 732).
