Abstract
A liquid supply system for use with an aerosol-generating device, the liquid supply system comprising a liquid retention material (136), a liquid flow channel extending from the liquid retention material and a barrier (125) disposed in the liquid flow channel, the barrier having a threshold temperature between 60° C. and 120° C., wherein the barrier is impermeable to liquid below its threshold temperature and the barrier becomes reversibly permeable to liquid above the threshold temperature.
Claims15
A liquid supply system for use with an aerosol-generating device, the liquid supply system comprising:
- a liquid retention material;
- a liquid flow channel extending from the liquid retention material;
- and
- a barrier disposed in the liquid flow channel, the barrier having a threshold temperature between 60° C. and 120° C., wherein the barrier is impermeable to liquid below its threshold temperature and the barrier becomes reversibly permeable to liquid above the threshold temperature, wherein the barrier comprises a polymer layer and a temperature reactive material dispersed therein, and wherein the temperature reactive material forms pores in the polymer layer above the threshold temperature.
