CARTRIDGE FOR AEROSOL GENERATING SYSTEM Russian patent published in 2022 - IPC A24F40/42 

FIELD: aerosol generating systems.

SUBSTANCE: inventions group relates to a cartridge for an aerosol generating system and the system itself. A cartridge for an aerosol generating system comprises a housing having an opening at the mouthpiece end and an air inlet, as well as a storage compartment located inside the housing and configured to receive a liquid aerosol-forming substrate. The storage compartment has a first compartment and a second compartment connected to each other by means of a connector so that liquid in the first compartment can flow into the second compartment through a fluid channel in said connector. The air flow channel extends from the air inlet to the opening at the mouthpiece end, the air flow channel extending between the first compartment and the second compartment. The liquid-permeable aerosol generating element has a first surface and a second surface opposite the first surface, wherein the first surface of the fluid-permeable aerosol generating element faces the first compartment and the second surface faces the second compartment and is in fluid communication with the second compartment so that the liquid aerosol-generating substrate in the first compartment can only reach the fluid-permeable aerosol-generating element through the second compartment, the first surface and the connector forming an airflow channel portion. The liquid aerosol-forming substrate in the first compartment can only reach the fluid-permeable aerosol-generating element through the connector and the second compartment.

EFFECT: invention makes it possible to prevent or at least reduce leakage and evaporation of the liquid aerosol-forming substrate during transport and storage.
