BRIEF DESCRIPTION OF THE FIGURE
In Figure 1 , a representative perspective view of the subject matter air sterilization device is given.
DETAILED DESCRIPTION OF THE INVENTION
In this detailed description, the subject matter air sterilization device (10) is explained with references to examples without forming any restrictive effect only in order to make the subject more understandable.
In Figure 1 , a representative perspective view of the subject matter air sterilization device (10) is given. Accordingly, said air sterilization device (10) is a portable harmful microorganism purification unit for cleaning virus and bacteria from air which are contaminated through the air. The air sterilization device (10) can be continuously and safely used in central ventilation systems (rooftop etc. hvac systems), hospitals, dentists, schools, kindergartens, shopping centers, shops, offices/workplaces, toilets/bathrooms, sports halls, lifts, closed areas like hairdressers, moreover, the different sized air sterilization device with different capacities can be safely used in all closed areas where lots of people exist like automobiles, taxies, buses, trains, etc. The air sterilization device (10) comprises at least one body (30). Said body (30) essentially has a shell structure and enables keeping air therein. Said body (30) comprises at least one inlet part (32). Said inlet part (32) is essentially an opening which allows intake of air. Said outlet part (33) is essentially provided in the completely opposite direction to the inlet part (32). The outlet part (33) is an opening which allows release of the cleaned air to the medium. The air sterilization device (10) comprises at least one air guidance element (34). Said air guidance element (34) is essentially a fan motor and enables discharge of the air which exists in the body (30). The air guidance element (34) is essentially positioned in the vicinity of the outlet part (33).
The body (30) comprises at least one separator (31 ). Said separator (31 ) allows separation of the body (30) into two chambers by extending lengthwise at least partially in the middle of the body (30). The separator (31 ) is a plate which affects passage of air through it. The body (30) comprises an air inlet corridor (I) in the entry direction of the air and at least one air outlet corridor (II) in the output direction of the air. Said air inlet corridor (I) and said air outlet corridor (II) are sections provided on one each sides of the separator (31 ).
The air sterilization device (10) comprises at least one first filter (20). Said first filter (20) is essentially a carbon filter. The first filter (20) is provided at the air inlet corridor (I), and it provides removal of contaminants like fume and fog from air, which enters the body (30), by means of a process called adsorption. The most important difference of the adsorption process realized by the first filter (20) is that the contaminants adhere to the outer side of carbon during the adsorption process. The contaminant is adsorbed into the structure as in a sponge. Carbon is a carbon atom cage connected to each other. The adsorption process provides filtering, namely capturing of the organic chemicals (gases) coming from the air for active carbon air filters. It adsorbs contaminants like bad smell, fume, etc. and prevents emitting of said contaminants to the medium. The air sterilization device (10) comprises at least one third filter (24). Said third filter (24) is essentially a G4 filter. The third filter (24) is provided at the air outlet corridor (II) and provides holding of the dust which exists in the air.
The air sterilization device (10) comprises at least one second filter (21). Said second filter (21) is essentially a hepa filter and particularly a H13 type hepa filter. The second filter (21 ) is positioned at the separator (31 ) so as to be close to an end thereof. The second filter (21) is a filter which captures particles with high efficiency. The second filter (21) provides holding of microbes, bacteria and spores which exist in the air and which are up to size of 0.3 microns. The second filter (21) is essentially provided at a far position to the inlet part (32) and is the part where the air passes from the air inlet corridor (I) to the air outlet corridor (II). The air sterilization device (10) comprises at least one ultraviolet light source (22). Said ultraviolet light source (22) is essentially an UV-C lamp and particularly UV-C lamp provided in a manner emitting ultraviolet light at wavelength of at least 254 nm. The ultraviolet light source (22) does not deteriorate the oxygen structure in the air by means of UV rays at wavelength of 254 nm and provides protection of the oxygen structure. The ultraviolet light source (22) provides purification of air from harmful microorganisms and at the same time it provides cleaning of air by deteriorating DNA / RNA structures of particles held onto the second filter (21). The ultraviolet light source (22) is positioned at the air inlet corridor (I) and at the air outlet corridor (II) such that one each ultraviolet light sources (22) are provided on both sides of the second filter (21). The air sterilization device (10) comprises one each light blockers (23) positioned on the side of the first filter (20) and the third filter (24) facing the light source. Said light blocker (23) is a plate which prevents passage of ultraviolet light and which allows passage of air. The light blocker (23) enables increase of the efficiency of ultraviolet light by forming one each chambers from both sides of the second filter (21 ). The light blocker (23) prevents unfavorable affecting of the first filter (20) and the third filter (24) by the ultraviolet light.
In an exemplary operation scenario of the present invention, air enters the air sterilization device (10) through the inlet part (32). At the air inlet corridor (I), the air, which passes through the first filter (20), is purified from contaminants like fume and fog. The ultraviolet light source (22), which emits ultraviolet light, provides purification of the air from harmful microorganisms and the air passes through the second filter (21 ) and is guided to the air outlet corridor (II). The second filter (21 ) provides holding of the particles which exist in the air. Again by means of the ultraviolet light source, the DNA/RNA structures of harmful microorganisms are fragmented without deteriorating the structure of oxygen in the air, and the air is cleaned. The thin dust which exists in the air which passes through the third filter (24) is eliminated, and the air is guided to the medium through the outlet part (33) by the air guidance element (34).
Together with all these embodiments, by means of the air sterilization device (10), DNA/RNA structures of the harmful microorganisms which exist in the air in the medium, particularly the viruses which lead to pandemic diseases are deteriorated by means of ultraviolet rays emitted by the ultraviolet light source (22), and sterilization is provided. Since the ultraviolet light source (22) has wavelength of 254 nm, the structure of the oxygen which exists in the air is protected, and no unfavorable effect for human health occurs. By means of the light blockers (23), the ultraviolet light source (22) has higher microbe killing effect in a chamber effect. By providing operation of the second filter (21 ) in a clean manner and for longer duration, the sterilization of the air sterilization device (10) is provided.
The protection scope of the present invention is set forth in the annexed claims and cannot be restricted to the illustrative disclosures given above, under the detailed description. It is because a person skilled in the relevant art can obviously produce similar embodiments under the light of the foregoing disclosures, without departing from the main principles of the present invention.
