<p>A respiratory protector comprises a nose adaptor, with an air passage opening (3), formed as a base (1); a cover (5); and at least one disk (5), fixed via a bulge on the base and comprising a housing (11), a bush (12) and a partition (13) consisting of sectors (17) with intermediate air passage gaps (18). The gaps, partition, disks, suction openings in the cover and the base together create a cyclone. A respiratory protector comprises a nose adaptor, with an air passage opening (3), formed as a base (1) adapted in size and shape to the nostril of the user; a cover (5); and at least one disk (5), fixed via a bulge on the base. The disk comprises a cylindrical annular housing (11), with a fixing ring and annular bulge in the lower and upper part respectively; an upwardly pointing truncated conical bush (12); and a partition (13) between the housing and bush, consisting of sectors (17) with intermediate gaps (18) for passage of inhaled air. Each sector is placed in the side of the bush, at an angle (possibly varying in sections of the sector) to the horizontal plane and to the perpendicular axis of the bush. The cover comprises suction opening plate(s), containing a groove (8) with a hygroscopic filling (9) and a conical finger (10) and having several openings. The gaps, partition, disks, suction openings and base together create a cyclone.</p> |
