Abstract

An electronic vaporizing device has an air flow tube passing through a liquid storage chamber ( 210 ). The air flow tube has a plurality of micro-openings ( 122 ). A thin film heating element ( 121 ) is provided on an inner wall of the air flow tube. A plurality of micro-openings in the thin film heating element ( 121 ) are aligned with the plurality of micro-openings in the airflow tube to provide a flow of liquid from the liquid storage chamber ( 210 ) to the thin film heating element ( 121 ).

First claim
