VAPOUR SUPPLY APPARATUS Russian patent published in 2022 - IPC A24F47/00 

FIELD: smoking devices.

SUBSTANCE: group of inventions relates to a vapour supply apparatus, a vapour supply system, and a non-therapeutic method for using a vapour supply apparatus. The vapour supply apparatus comprises a main air flow channel located inside the vapour supply apparatus and extending from the air inlet to the air outlet so that when the user inhales, the air is drawn through said main channel from the air inlet in the direction of the downstream side to the air outlet. The apparatus comprises an evaporator for supplying vapour to the main air flow channel located in or near the main air flow channel, a capturing apparatus located in the main air flow channel for preventing the flow of liquid in the main air flow channel in the direction of the upstream side from the capturing apparatus by retaining liquid, and an air flow sensor for detecting inhalation of the user using the apparatus. The capturing apparatus is located downstream from the air flow sensor.

EFFECT: flow of liquid to the upstream side is prevented while simultaneously maintaining the air flow to the upstream side during inhalation of the user, and placement of other components in the electronic cigarette is facilitated.
