DEVICE FOR INDEPENDENT THERMAL COMFORT OF HUMAN BODY Russian patent published in 2009 - IPC A62B18/02 A62B7/10 

FIELD: items of personal use and for household.

SUBSTANCE: invention refers to means of individual protection of human body in general and respiratory organs in conditions of thermal discomfort at low and reduced, increased and high temperatures, as well as for return of lost with respiration moisture with a complex cleaning of the in-breathing air from dust, suspended materials, plant pollen, bacterias, viruses and gas impurities at the environment temperature from -64°C till +125°C and higher. Device for independent thermal comfort of human body has shape and sizes resembling the shape and proportion of sizes of the lower part of a face and contains section from case with central hole on the inner side for work respiration from textile fabric that does not render pneumatic resistance to air flows in which there is insert in the shape of inner section from several put one on another perforated or netlike elements. The netlike elements are sodden with hardening compound and form heat-exchange surface bent outward with alternate radius package from units till dozens millimeters thick. Radius of the bend and square of the inner surface of the element is more than the radius of the bend and square of its inner surface. The device additionally contains consequently situated in the insert above the inner section and forming therewith a single thermal block a middle self-humidifying section that is made from netlike elements, and the outside section from several put one onto another perforated or netlike elements sodden with hardening compound. The netlike elements of each section are made from natural fabrics, each section forms a heat-exchange surface in the shape of bent outward with alternate radius package from units till dozens millimiters thick. Radius of the bend and square of the outer surface are more than the radius of the bend and square of its inner surface, and square of each subsequent square is more than the square of the previous one. Thickness of netlike element set in each section and air intervals between them amounts to several millimeters. In parallel to the work channel for respiration including the central hole there is additional regulator for decrease of coefficient of efficiency.

EFFECT: widening of operational possibilities of device.
