FLUID-PERMEABLE HEATER ASSEMBLY FOR AEROSOL-GENERATING SYSTEMS Russian patent published in 2020 - IPC A24F47/00 

FIELD: heating; devices for spraying or spraying liquids.

SUBSTANCE: fluid-permeable heater assembly for aerosol-generating systems, having electrically conductive flat ordered filamentary structure and first contact point (28) and second contact point (48) for providing electrical contact with flat ordered filamentary structure, wherein longitudinal axis is formed between first contact point (28) and second contact point (48). Resistance of central area Rc is electric resistance between two points located on longitudinal axis, wherein one of the two points is located at a distance from the first contact point (28) equal to 40 percent, and the other of the two points is located at a distance from the first contact point (28) of 60 percent. First resistance R1 is electric resistance between first contact point (28) and point, located on longitudinal axis at distance from first contact point (28) equal to 20 percent, and second resistance R2 is electric resistance between second contact point (48) and point, located on longitudinal axis at distance from first contact point (28) equal to 80 percent. Resistance ratio of the central region to the first resistance, Rc/R1, ranges from 2 to 400, and the ratio of resistance of the central region to the second resistance, Rc/R2, ranges from 2 to 400.

EFFECT: disclosed is a fluid-permeable heater for aerosol generating systems.
