CARTRIDGE FOR EVAPORATION DEVICE (VARIANTS) AND EVAPORATION DEVICE Russian patent published in 2023 - IPC A24F40/30 A24F40/40 

FIELD: tobacco industry.

SUBSTANCE: group of inventions relates to the systems simulating the process of smoking. The vaporizer cartridge comprises a primary reservoir having a first pressure state and a second pressure state. The primary reservoir is configured to expel vaporized matter in response to an increase in free space above the matter while in the second pressure state. The secondary reservoir is in fluid communication with the primary reservoir. The secondary reservoir is made of absorbent material, which is configured to receive the first volume of the vaporized substance from the primary reservoir in the first pressure state and to receive the second volume of the vaporized substance from the primary reservoir in the second pressure state, the second volume being larger than the first volume. The evaporation chamber is in communication with the secondary reservoir and includes a first absorbent element configured to draw vaporized matter from the secondary reservoir chamber into the evaporation chamber for evaporation by means of a heating element. The primary reservoir is configured to store a larger proportion of the volatilized substance in the first pressure state compared to the secondary reservoir. According to the second variant of the cartridge, the first absorbent element extends between the primary and secondary reservoirs and is configured to draw the vaporized substance from the primary reservoir into the secondary reservoir. The evaporation chamber is in communication with the secondary reservoir and includes a second absorbent element configured to draw vaporized matter from the secondary reservoir into the evaporation chamber for evaporation by means of a heating element. An evaporator device is claimed.

EFFECT: prevention of leakage of the evaporated substance due to the absorption of its excess.
