FIELD: steam supply system.
SUBSTANCE: invention relates to an electronic steam supply system, e.g. an electronic cigarette. Electronic steam supply device comprises: a first electric resistive heater configured to evaporate the starting material in order to generate steam in an air stream for inhalation by the user, and a second electric resistive heater configured to evaporate the feed material and / or heat said air stream. First electric resistive heater has the first temperature coefficient of resistance, which is lower than the second temperature coefficient of resistance of the second electric resistive heater. Device additionally comprises control system to monitor change of resistance of at least second electric resistive heater. Therefore, the second electric resistive heater serves both as a heater and as a temperature monitoring device.
EFFECT: disclosed is an electronic steam supply device.
