AI Technical Summary

Technical Problem

Existing aerosol-generating systems face challenges in maximizing aerosol delivery to the user while minimizing condensation and leakage within the device, particularly at the interface between the cartridge and the device components.

Method used

Incorporation of a compliant sealing element that contacts the external surface of the cartridge to provide a seal between the lid and the cartridge, circumscribing the airflow path, which reduces leakage and condensation, and allows for a low-force connection, enhancing mechanical durability.

Benefits of technology

The compliant sealing element effectively prevents aerosol leakage and condensation, improving aerosol delivery efficiency and mechanical durability by ensuring a consistent seal and reducing stress on mechanical components.

Abstract

An aerosol-generating system (200) comprising a cartridge (100) containing an aerosol-forming substrate (116) and an aerosol-generating device (300) configured to at least partially receive the cartridge (100). The cartridge (100) comprising an airflow path (112) between a first inlet (107) and a first outlet (108). The aerosol-generating device (300) comprising a device body (301) and a lid (302). The lid (302) defining a lid airflow path (312) between a second inlet (308) and a second outlet (303). The lid (302) having a closed position in which the lid (302) is configured to engage the cartridge (100) such that the second inlet (308) is aligned with the first outlet (108). The lid (302) comprising a compliant sealing element (311) which contacts an external surface of the cartridge (100) to provide a seal between the lid (302) and the cartridge (100). The compliant sealing element (311) circumscribing the cartridge airflow path (112) or the lid airflow path (312).
