Abstract

The present invention provides device for cleaning air fouled by bathroom usage, and more particularly an air cleaning device having: a housing for holding air extraction mechanism, air filtration mechanism, mechanism for germicidal treatment of air, and air refreshing mechanism; a foul air containment ring mechanism; an extractor tube mechanism connecting containment ring to filtration mechanism. The containment ring mechanism confines air fouled by bathroom usage from escaping the bowl area and using with air breathe by user. The extractor mechanism forces the confined fouled air to the filtration mechanism through the extractor tube. Odor causing molecules along with bacterial and viral bodies are removed at the filtration mechanism. The extractor mechanism subsequently forces the filtered air through the refresher mechanism where fragrances are added to the air before the air is returned to the room's air mass.

1 . A device for removing odors form air fouled through bathroom 
 usage before same fouled air mixes with air breathe by user comprising in combination:    a containment mechanism for confining air and odorous gases produced by toilet usage to toilet bowl area;    an extraction mechanism for creating the forces needed to draw same confined air and odorous gases from toilet bowl area;    a filtration mechanism for removing odorous gases from fouled air;    at least one path through which fouled air confined to bowl area is directed to move through confinement mechanism to the filtration mechanism;    a means for germicidal treatment of filtered air;    a mechanism for refreshing the filtered air before the return of same air to the room environment;    and wherein in same device, the containment mechanism prevents air containing odorous gases from escaping toilet bowl area, the extractor mechanism extracts same trapped air and odorous gases through at least one path, the extractor mechanism forces same air and odorous gases through the filtration mechanism, the filtration mechanism traps the odorous gas molecules and removes them from the air, the filtered air is germicidally treated, the extractor mechanism pushes the filtered and treated air through the refresher mechanism, and the refresher mechanism adds fragrances to the air before same air is returned to room's air mass.    
   
   
       2 . A containment ring mechanism for confining air and odorous gases to bowl area comprising: 
 a containment ring contoured to fill the space normally existing between the bottom of toilet seat and top of toilet bowl;    said containment ring having central opening for passage of waste materil;    said containment ring made of material including materials suited for wet conditions;    said containment ring is attached to location including top of toilet bowl or bottom of toilet seat to form airtight seal between the bottom of toilet seat and top of toilet bowl;    said containment ring having at least one opening or bore through its back end to allow the extraction of trapped air and odorous gases; said bore positioned at angles including horizontal angle and angle tilted downward towards bowl to prevent intake of water, and said bore capable of accepting one end of extractor tube;    said containment ring having multiple bores spatially arrayed around containment ring and spatially related to each other; each fitted to a single branch from compound end of extractor tub and each tilted at a downward angle towards bowl to prevent intake of water;    and wherein containment ring forms barrier to prevents odorous gases from escaping through space between bowl and bowl seat into the room's air mass.    
   
   
       3 . A containment mechanism for confining air and odorous gases according to  claim 2  includes air inflow from room's air mass into bowl; said air inflow into bowl produced by means including the extraction of air from bowl by extractor mechanism to cause low pressure area and initiate movement of surrounding air of higher pressure into area of lower pressure, and wherein air flowing into bowl area prevents foul air from moving outwards and mixing with room's air mass.  
   
   
       4 . An extraction mechanism for creating the forces needed to draw trapped air from bowl area according to  claim 1  comprising: 
 a housing for motor-fan assembly;    a motor fan assembly means having at least one set of fan blades and capable of insertion into housing;    a protective barrier at either end of housing to prevent accidental contact with rotating fan blades; said barriers allowing the free movement of air through housing;    and wherein rotating fan blades force odorous air out of the bowl area, through the extractor tube, through the filtration medium, through the refresher mechanism and out of the courtesy pump device into the room's air mass.    
   
   
       5 . A path through which fouled air first confined to the bowl area is made to move from same bowl area to the filtration mechanism in accordance with  claim 1  includes a hollow, flexible extraction tube connecting containment ring and filtration unit and wherein fouled air is forced from bowl area through same hollow tube by action of the extractor mechanism.  
   
   
       6 . A filtration mechanism for removing odorous gases from fouled air in accordance with  claim 1  comprising: 
 a housing;    a holder for keeping filter medium in position; said holder having a structure including that of a rubber ring having a horizontal groove on its inner circumference for securing filter medium, and said holder forming an air tight seal between both the housing and the filter medium;    a filter medium including medium such as activated charcoal, secured within the filter holder;    and wherein in same filtration mechanism odorous air is forced through filtration medium by extractor, and filtration medium traps and removes odor causing molecules to allow only non odor causing molecules to pass through same medium.    
   
   
       7 . A means for germicidal treatment of filtered in accordance with  claim 1  comprises a germicidal barrier; said barrier including the treatment of filter medium with germicide.  
   
   
       8 . A mechanism for refreshing the filtered air in accordance with  claim 1  includes: 
 an inverted cup-shaped device having an opening at bottom center and perforations on side walls, and capable of being attached to extractor housing;    a fragrance holder having shape including shape of test tube and having perforations at its upper end, and capable of being positioned in bottom center opening of inverted cup-shaped device;    and wherein fragrance holder contains fragrances including liquid and solid fragrances and in which perforations in fragrance holder allows fragrance molecules to exit holder and mix with filtered air, and refreshed air exits perforations in inverted cup-shaped device into the room's air mass.    
   
   
       9 . A mechanism for providing air-tight connections between component sections including connecting sleeve device capable of being inserted into adjoining ends of independent component sections.
