ELECTRICALLY-DRIVEN SYSTEM GENERATING AN AEROSOL WITH A LIQUID PUMP Russian patent published in 2020 - IPC A24F47/00 

FIELD: engines and pumps.

SUBSTANCE: electrically driven system which generates an aerosol, comprising: liquid reservoir (120) comprising a rigid body; inlet air valve (122) in rigid housing, made so as to allow air to flow into the liquid container when pressure difference outside the housing and inside the housing exceeds the threshold pressure difference; evaporator (134), made with possibility of liquid evaporation; pump (132) connected to outlet hole in rigid housing and made with possibility of pumping liquid from liquid reservoir to evaporator.

EFFECT: present invention provides a pump between a liquid container and an evaporator; this improves reliability and efficiency of fluid delivery to the wick; besides, this invention provides inlet air valve in liquid reservoir; this allows to equalize pressure inside tank with atmospheric pressure; in turn, this allows to use a rigid housing of the reservoir, providing the reservoir for liquid with the required reliability.
