INDIVIDUAL UV MASK-TYPE RECIRCULATOR

摘要

FIELD: protective devices.;SUBSTANCE: invention relates to the field of protective devices, primarily of the respiratory system against bacteria and viruses. An individual ultraviolet mask-type recirculator includes a mask with a first hole and a cleaning unit containing a housing with a second hole and with an internal cavity, the second opening of the housing being mated with the first opening of the mask. The housing is connected to the lid having third openings, while the first UV source is installed in the housing cavity, connected to the power and control unit. A first diaphragm with fourth holes and a second diaphragm with fifth holes are installed in the inner cavity of the housing between the second hole and the first ultraviolet radiation source, while the third holes in the cover, fourth holes in the first diaphragm and fifth holes in the second diaphragm are located so that their axial projections on the plane do not coincide with each other, and the generators of the fourth holes in the first diaphragm and the fifth holes in the second diaphragm are located at angles to the planes of the first diaphragm and the second diaphragm, not equal to 90°. The cover is mounted on the body with the possibility of removability and adjusting movement of the cover around the axis of symmetry.;EFFECT: increasing the effectiveness of protection against bacteria and viruses.;2 cl, 5 dwg
