AEROSOL GENERATING DEVICE Russian patent published in 2021 - IPC F04B43/04 A24F47/00 A61M15/06 

FIELD: aerosol generators.

SUBSTANCE: aerosol generating device comprises a cartridge for holding the aerosol-forming substrate, a sprayer for spraying the aerosol-forming substrate, and a micro-pump (1) for delivering the fluid. The micro-pump (1) is located between the cartridge and the sprayer to supply the substrate forming the aerosol from the cartridge to the sprayer. The micro-pump (1) comprises two chambers (2) of the pump having two separate chamber volumes and two actuating elements (6), each actuating element (6) being connected by one of the two chambers (2) of the pump to change the volume of the corresponding chamber, and each chamber (2) of the pump being provided with at least one inlet valve (30) and at least one outlet valve (31). The two chambers (2) of the pump are arranged in parallel and in a fluid connection with a common inlet (4) and a common outlet (5) to establish the direction of the pump flow along the fluid path, while the fluid path does not contain angles of 90 degrees or less. The actuators (6) are designed to operate in parallel, so that the volume change in each of the two chambers (2) of the pump occurs simultaneously for both chambers (2) of the pump.

EFFECT: delivery of a more uniform aerosol is ensured.
