AI Technical Summary

Technical Problem

The risk of leakage of liquid aerosol precursor materials in electronic cigarettes can lead to damage to the control unit and reliability issues, while insufficient liquid may cause the heating element to overheat and produce undesirable odors.

Method used

Design a smoke cartridge structure that includes an air channel, a heating element, and a valve. Air enters the aerosol generation area through the air valve and exits through the outlet. Combined with the power supply and control circuit of the control unit, selective power supply to the heating element is achieved, reducing the risk of liquid leakage.

Benefits of technology

It effectively reduces the risk of leakage of liquid aerosol precursor materials, ensures the reliability of the control unit and the stable operation of the heating element, and avoids overheating and unpleasant odors caused by insufficient liquid.

Abstract

The present application relates to an aerosol provision system, in particular to a cartridge for use in an aerosol provision system and a cartridge, the aerosol provision system comprising a cartridge and a control unit. The cartridge comprises: an air passage extending from an air inlet of the cartridge, via an aerosol generation region, to an outlet; a heating element for heating aerosolisable material (e.g. liquid) from a reservoir to generate an aerosol in the aerosol generation region; and a valve located in the air passage upstream of the aerosol generation region. The cartridge is configured such that air passing through the air passage is configured to pass from the air inlet, through the air valve, into the aerosol generation region, and then out from the aerosol outlet.
