Abstract
Sposób zabezpieczania przed rozprzestrzenianiem się wydychanych zanieczyszczeń powietrza polega na tym, że wydychane powietrze zasysa się z podciśnieniem od 2 x 105 do 10 x 105 Pa i wydajnością od 100 do 330 l/min ze strefy najbliższego otoczenia nosa i ust użytkownika przez regulowaną szczelinę lub otwory (1) wlotowe powietrza, znajdujące się w dolnym segmencie obramowania (2) przeźroczystej osłony (6) twarzowej, a następnie odprowadza się poprzez zauszniki (3), przewód (4) elastyczny do modułu (5) wytwarzającego podciśnienie i poza chronioną strefę. Urządzenie składa się z przeźroczystej osłony (6) twarzowej o przeciwodblaskowych i przeciwmgielnych właściwościach, w której w dolnym segmencie obramowania (2), stanowiącym kanał przepływu powietrza, znajduje się regulowana szczelina lub otwory (1) wlotowe powietrza odprowadzanego poprzez zauszniki (3), a następnie przewód (4) elastyczny do modułu (5) wytwarzającego podciśnienie.The method of protection against the spread of exhaled air pollutants is that the exhaled air is sucked at a negative pressure of 2 x 105 to 10 x 105 Pa and a capacity of 100 to 330 l / min from the zone of the immediate vicinity of the nose and mouth of the user through the adjustable gap or holes (1) the air inlet, located in the lower segment of the frame (2) of the transparent face shield (6), and then discharged through the temples (3), the flexible hose (4) to the module (5) generating negative pressure and outside the protected area. The device consists of a transparent face shield (6) with anti-reflective and anti-fog properties, in which the lower segment of the frame (2), which is the air flow channel, has an adjustable gap or holes (1) for air inlet drawn through the temples (3), and then a hose (4) to the vacuum module (5).
