SPRAYING HEATING UNIT AND SPRAYING HEATING DEVICE USING IT Russian patent published in 2024 - IPC A24F40/40 A24F40/42 A24F40/465 

FIELD: spraying technique.

SUBSTANCE: group of inventions relates to a spraying heating unit and a spraying heating device of an electronic cigarette. Spraying heating unit comprises a liquid transfer unit and a heating unit. Liquid transfer unit is a porous liquid transfer unit, and the heating unit is a magnetically conductive porous heating unit. Porous unit for transfer of liquid is made in the form of porous structure with pores of micron size, formed by high-temperature sintering of inorganic non-metallic aggregate and binder. Magnetically conductive porous heating unit is made in form of magnetically conductive porous structure, formed by direct high-temperature sintering of particles of magnetically conductive material or high-temperature sintering of particles of magnetically conductive material and binder. Magnetically conductive porous heating unit is at least inserted into the surface of the porous liquid transfer unit or attached to it, and the open surface of the magnetically conductive porous heating unit located in the spraying channel forms a spraying surface. Spraying heating device comprises a housing, a mouthpiece, a liquid reservoir and the disclosed spraying heating unit located under the liquid reservoir, and a sealing element is located between the spraying heating unit and the liquid reservoir.

EFFECT: simplification of design and prevention of dry burning of liquid forming aerosol.
