DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0048] Now, the present invention will be illustrated purely by way of non-limiting or non-binding example, with reference to the figures illustrating some embodiments regarding the present inventive concept.

[0049] The outer aspect of the preferred embodiment of the purifier of the present invention is shown with reference to FIG. 1.

[0050] It is cylindrical-shaped, with an upper protection lid 3 and a base 4 which allows the purifier to be integrally joined to the ground.

[0051] The lateral surface of the cylinder consists of an openable protection guard 1 and of an upper grid 2 with rings identical to a lower grid 2′ with rings. Internally, as shown in FIG. 2, a support system 5 holds an air treatment duct 6 and an axial fan 7 which suctions air from the external conveying it into the duct 6, in the position previously provided for.

[0052] In order to eliminate the potentially toxic substances, the external air which is conveyed in the treatment duct 6, flows through at least three filters 8 coupled with LED lights 9. Said filters 8 are made of alveolar ceramic alloy, so as to optimise the volume/surface ratio and thus make system efficient to the utmost. Said filters 8 are subsequently treated with Titanium Dioxide (TiO.sub.2) nano-coatings, which, when impacted by the LED light, start a photocatalysis process which disintegrates pollutant substances, toxic substances, bacteria and virus into salts and other harmless substances.

[0053] All the other surfaces of the purifier, except for those of the filters, are treated with protection nano-coatings.

[0054] Due to its ease of installation and operation, the purifiers of the present invention are suitable to be installed outdoors, preferably in urban centres more subject to pollution, places particularly exposed to bacterial risks, such as workplaces, schools and hospitals.

[0055] An example of such variants is obtained by manufacturing the purifier in the “table” version, i.e. small dimensions, and possibly provided with technical/aesthetic solutions like in the example indicated in FIG. 4. In this case, the purifier also serves as a table lamp thanks to the fact that the outer guard 1 is transparent and covered with longitudinal strips 10-10′ -10″ which modulate and filter the light coming from the LED lights 9 inside the purifier. The use currently deemed most convenient for a purifier thus made, is the office use, i.e. placing a purifier for each desk of a work environment. Besides being aesthetically appealing, such purifiers are sources of lighting for the desk and they purify the air breathed by all employees of an office from bacteria, virus and other impurities according to the same methods described above.

[0056] Lastly, it is clear that the invention described up to now may be subjected to modifications, additions or variants obvious to a man skilled in the art, without departing from the scope of protection outlined by the attached claims.
