The ring can also be made of a transparent or translucent material to allow a user to detect whether a UV lamp within the housing is operating. An improved nut for affixing a quartz tube within such a unit and improved design for draining the unit are also disclosed. ## Claims ### Claim 1 An ultraviolet light sanitation apparatus comprising: a housing; a ventilation ring incorporated into the housing for allowing heated air to exhaust from the housing, the ventilation ring comprising downwardly facing ventilation openings whereby the ventilation openings are shielded from sources of overhead moisture while preventing intrusion of moisture from outside of the apparatus into the housing. ### Claim 2 (depends on 1) The ultraviolet sanitation apparatus of claim 1, wherein the ventilation ring is mounted on top of a water tank housing of the apparatus. ### Claim 3 (depends on 2) The ultraviolet sanitation apparatus of claim 2, wherein the tank housing has a diameter and the ventilation ring has at least one flange projecting to a greater diameter than the diameter of the tank housing. ### Claim 4 (depends on 3) The ultraviolet sanitation apparatus of claim 3, wherein the ventilation openings are located in the at least one flange. ### Claim 5 (depends on 4) The ultraviolet sanitation apparatus of claim 4, further comprising a bonnet housing electrical components, the bonnet housing having an internal perimeter slightly larger than the at least one flange. ### Claim 6 (depends on 5) The ultraviolet sanitation apparatus of claim 5, wherein the bonnet is adapted to fit over the ventilation ring. ### Claim 7 (depends on 6) The ultraviolet sanitation apparatus of claim 6, wherein the ventilation openings in the at least one flange of the ventilation ring allow heat generated within the bonnet to escape downwardly from the bonnet while preventing moisture from entering the bonnet from a top or a side of the bonnet. ### Claim 8 (depends on 3) The ultraviolet sanitation apparatus of claim 3, wherein the ventilation ring comprises six of the flanges equally disposed about as outer perimeter of the ventilation ring. ### Claim 9 (depends on 1) The ultraviolet sanitation apparatus of claim 1, wherein the ventilation ring is made from a clear or translucent material to create a window between the water tank housing and the bonnet. ### Claim 10 (depends on 7) The ultraviolet sanitation apparatus of claim 7, wherein the water tank housing comprises a body tube, the body tube comprising a water inlet port and a water outlet port for injecting water into the body tube and for exhausting water from the body tube, respectively. ### Claim 11 (depends on 10) The ultraviolet sanitation apparatus of claim 10, wherein the body tube is mounted on a mounting base that rests on a surface and an upper end of the body tube is capped with a body end cap. ### Claim 12 (depends on 11) The ultraviolet sanitation apparatus of claim 11, wherein the ventilation ring is affixed to the body end cap. ### Claim 13 (depends on 12) The ultraviolet sanitation apparatus of claim 12, further comprising a shoulder cut formed in the body end cap to receive the ventilation ring. ### Claim 14 (depends on 13) The ultraviolet sanitation apparatus of claim 13, further comprising a heat shield disk to shield the bonnet from direct heat from electronic components of the apparatus. ### Claim 15 (depends on 1) The ultraviolet sanitation apparatus of claim 1, wherein the ventilation ring is a ventilation glow ring used to indicate ultraviolet lamp operation. ### Claim 16 (depends on 15) The ultraviolet sanitation apparatus of claim 15, further comprising at least one plug port configured as an opening at an end of the body tube. ### Claim 17 (depends on 16) The ultraviolet sanitation apparatus of claim 16, wherein the at least one plug port is used for the insertion of a quartz tube into which an ultraviolet lamp is placed. ### Claim 18 (depends on 16) The ultraviolet sanitation apparatus of claim 16, wherein the at least one plug port is used as a drain.
