Definitions
- the invention relates to devices for cleaning, filtering and sterilizing air and can be used in combination with personal protective equipment for people, in particular masks and respirators for protection against viral and bacterial infections transmitted by airborne droplets using multi-stage filtration and ultraviolet radiation sterilization.
- a patent is known for the invention of the Russian Federation "Photonic quantum mechanical (FCM) protective mask” [1], containing a protective housing with means of fastening on the face of the mask wearer and a bactericidal chamber, the inner surface of which is made of a material that reflects ultraviolet radiation, equipped with an air filter, made of a material that absorbs ultraviolet radiation, a source of ultraviolet radiation located inside the bactericidal chamber and connected to a power supply unit, characterized in that the source of ultraviolet radiation is made in the form of a UV-C LED, the bactericidal chamber is made in the form of a spheroidal closed cavity with a surface perforated with holes , while the air filter of the bactericidal chamber is installed so that it the inner surface tightly fit the outer surface of the bactericidal chamber, and the bactericidal chamber itself is hermetically installed in the protective body of the mask so that a cavity is formed between the outer surface of the bactericidal chamber and the inner part of the shell of the protective body
- the disadvantages of this design is the uneven intensity of the flow of ultraviolet radiation in different parts of the proposed device and insufficient air filtration.
- a patent is known for a utility model of the Russian Federation "Protective medical mask” [2], which contains a housing with brackets for attaching fixing belts, on which a replaceable filter for initial air purification is located, in turn, in the inner part of which there is an electronic board with activation LEDs of the ultraviolet spectrum, characterized in that a photocatalytic filter made of titanium dioxide is used as a bactericidal filter with an internal filter located behind it, designed for filtration.
- the technical objective of the invention is to improve the quality of air purification for breathing.
- the ultraviolet sterilizer contains a heat removal unit, an emission unit, at least one filter, a housing cover, a power cable, a power connector, latch of the power wire, at least one air flow swirler, at least one ultraviolet radiation source and at least one air duct and contains a lower air flow swirl in which the air duct is made in the form of a sector with a radius R1, which is in the range from 1 mm to 120 mm and with an angle a which is in the range from 1° to 180° and an upper swirler of the air flow, in which the air duct is made in the form of a ring sector with a length of radii R2 and R3 in the range from 1 mm to 100 mm and with an angle b which is in the range from 1 ° up to 180°, moreover, the upper swirler is made of a material transparent to ultraviolet radiation, the radiation unit is made in the form of a circle and contains at least one radiation source, it also contains electrostatic and quartz filters, and the housing is made in
- Ultraviolet sterilizer containing a heat dissipation unit (1) , radiation unit (2), a microfiber quartz filter (C), a housing (4), an electrostatic filter (5), a housing cover (b), a power cable (7), a power connector ( 8) , power wire latch(9), lower air swirl(U), upper air swirl(11), at least one source ultraviolet radiation (12), the air duct of the lower swirler of the air flow (13) and the air duct of the upper swirl of the air flow (14).
- a heat dissipation unit (1) containing a heat dissipation unit (1) , radiation unit (2), a microfiber quartz filter (C), a housing (4), an electrostatic filter (5), a housing cover (b), a power cable (7), a power connector ( 8) , power wire latch(9), lower air swirl(U), upper air swirl(11), at least one source ultraviolet radiation (12), the air duct of the lower swirler of the air flow (13) and the air duct of the upper swirl of the air
- the air duct (13) is made in the form of a sector with a length of radius R1, which is in the range from 1 mm to 120 mm and with an angle a, which is in the range from 1 ° to 180 ° and the upper air flow swirler (11)
- the air duct (14) is made in the form of a ring sector with a length of radii R2 and R3 in the range from 1 mm to 100 mm and with an angle b which is in the range from 1° to 180°
- the upper swirler is made from a material transparent to ultraviolet radiation
- the radiation unit (2) is made in the form of a ring and contains at least one source of ultraviolet radiation (12), while it contains electrostatic (5) and quartz filters and the housing is made in the form of a truncated cone.
- the sterilizer works as follows:
- the ultraviolet sterilizer is attached to the face mask or respirator by means of a mechanical connection located on the cover of the housing (b); this connection can also be bayonet.
- the inhaled air mixture passes through the air intakes (15) of the housing cover and enters the electrostatic filter (5) in which the primary air purification takes place.
- the air mixture enters the housing (4) where it begins to rotate around the upper swirler (1 1) of the air flow, thereby increasing the distance of passage in the body (4) tapering upwards due to its conical shape to the microfiber quartz filter ( ⁇ ), in which the air mixture is re-cleaned and enters the upper swirler (1 1) of the air flow, which is made of a material transparent to ultraviolet radiation.
- air sterilization continues with ultraviolet radiation from the radiation unit (2) using ultraviolet radiation sources (12), powered by a power cable (7) connected to the power connector (8) and attached to the housing (4) using the power cord latch (9). Air purified from bacteria, viruses, fungi and other microorganisms due to two-stage filtration and ultraviolet sterilization enters through the cover of the housing (b) for breathing.
- the invention can be implemented industrially using known technical means.
