AI Technical Summary

Technical Problem

Aerosol generators face issues with aerosol leakage due to manufacturing tolerances and the use of polymer seals that degrade under heating, leading to inefficient heat transfer and inconsistent product quality.

Method used

A method for quality testing airflow paths by pressurizing the path to a predetermined pressure, measuring leakage, and determining if it exceeds an acceptable threshold, allowing for the identification and potential refurbishment or discard of products with unqualified airflow paths.

Benefits of technology

Ensures consistent product quality by identifying and addressing airflow path leaks, improving heat efficiency, and maintaining product integrity.

Abstract

A method is provided for quality testing an airflow path defined in a product comprising a plurality of components coupled together to form the product, each component defining a portion of the airflow path, the method including pressurizing the airflow path to a predetermined pressure, measuring leakage from the pressurized airflow path for a predetermined period of time, determining an amount of leakage over the predetermined period of time, and determining whether the amount of leakage is greater than an acceptable threshold amount of leakage.
