ELECTRONIC VAPOUR DELIVERY SYSTEM Russian patent published in 2018 - IPC A24F47/00 

FIELD: tobacco industry.

SUBSTANCE: present invention relates to electronic vapour delivery systems, such as electronic nicotine delivery systems (for example, electronic cigarettes). Electronic vapour delivery system comprises an evaporator designed to vaporize the liquid for inhalation by the user of electronic vapour delivery system; power source comprising a battery or an accumulator battery for supplying electric power to the evaporator; air flow rate through an electronic vapour delivery system measuring sensor, wherein the air flow is the result of the user's inhalation; and a control unit intended for iteratively controlling the supply of electricity to the evaporator, so that the electronic vapour delivery system is provided with provision of an inhalation for each iteration during the process: measuring the current air flow rate; adjusting the cumulative air flow by summing up of the current air flow rate measurements made by the sensor for the current moment during inhalation; and control over the power supply using the evaporator control unit based on the corrected total air flow for this iteration and the desired relationship between the cumulative air flow for inhalation and amount of the vapour output to the user for inhalation; which allows the user to control the amount of vaporized liquid obtained for a given inhalation, based on the total air flow for a given inhalation.

EFFECT: technical results of the invention are flexibility, responsiveness and ease of use.
