Abstract

An air sanitizing apparatus for a vehicle comprising: an ozone generator; a negative ion generator; and an ultraviolet radiation source. The air sanitizing apparatus further includes a rotating feature and a motor operably connected to the rotating feature, the rotating feature configured to move the air sanitizing apparatus along a track system. The air sanitizing apparatus can include a first end portion; a second end portion; a middle portion disposed between the first end portion and the second end portion, the middle portion rotatable relative to the first end portion and the second end portion about an axis that extends through both the first end portion and the second end portion. The ozone generator, the negative ion generator, and the ultraviolet radiation source are all disposed at the middle portion. The air sanitizing apparatus is disposed in an interior of a vehicle below but adjacent to a ceiling.

First claim

What is claimed is:

1. An air sanitizing apparatus for a vehicle comprising:
an ozone generator;
a negative ion generator;
an ultraviolet radiation source;
a first end portion;
a second end portion;
a middle portion disposed between the first end portion and the second end portion, the middle portion rotatable about an axis that extends through the first end portion and the second end portion; and
an access panel disposed at a top portion of the middle portion;
wherein, the first end portion and the second end portion each comprise a rotating feature and a motor operably connected to the rotating feature, the rotating feature configured to move the air sanitizing apparatus along a track system;
wherein, the ozone generator, the negative ion generator, and the ultraviolet radiation are disposed at the middle portion.

2. The air sanitizing apparatus of claim 1 wherein the access panel is a vented access panel.

3. The air sanitizing apparatus of claim 1 , wherein
the first end portion and the second end portion each further comprise a second rotating feature and a second motor operably connected to the second routing feature; and
the ozone generator, the negative ion generator, and the ultraviolet radiation source are all disposed at the middle portion.

4. The air sanitizing apparatus of claim 1 ,
the middle portion including a rounded extension;
one or more of the first end portion and the second end portion including rounded indents positioned to selectively receive the rounded extension of the middle portion depending on a degree of rotation of the middle portion;
at one degree of rotation of the middle portion, the rounded extension extends into one of the rounded indents; and
at another degree of rotation of the middle portion, the rounded extension extends into another of the rounded indents.

5. The air sanitizing apparatus of claim 1 further comprising:
an air flow tube having an inside through which air can flow; and
an exhaust fan disposed at an end of the air flow tube and configured to cause air to flow through the inside of the air flow tube;
wherein, the ultraviolet radiation source is configured to irradiate ultraviolet radiation into the inside of the air flow tube.

6. A vehicle comprising:
a ceiling;
an interior with air disposed therein; and
an air sanitizing apparatus disposed in the interior below but adjacent to the ceiling, the air sanitizing apparatus comprising:
a first end portion;
a second end portion;
a middle portion disposed between the first end portion and the second end portion, the middle portion rotatable about an axis that extends through the first end portion and the second end portion;
an access panel disposed at a top portion of the middle portion; and
(i) an ozone generator that, when activated, generates ozone into the interior; (ii) a negative ion generator that, when activated, negatively ionizes molecules in the air of the interior of the vehicle; and (iii) an ultraviolet radiation source that, when activated, irradiates the air of the interior with ultraviolet radiation;
wherein, the first end portion and the second end portion each comprise a rotating feature and a motor operably connected to the rotating feature, the rotating feature configured to move the air sanitizing apparatus along a track system; and
wherein, the ozone generator, the negative ion generator, and

the ultraviolet radiation source are disposed at the middle portion.

7. The vehicle of claim 6 , wherein
the track system comprises a first track and a second track;
the first end portion of the air sanitizing apparatus is disposed adjacent the first track,
the second end portion of the air sanitizing apparatus is disposed adjacent the second track, and
the axis about which the middle portion of the air sanitizing apparatus is rotatable is orthogonal to the first track and the second track.

8. The vehicle of claim 6 , wherein
the vehicle further comprises a controller in communication with the ozone generator;
the controller is in further communication with locks of doors of the vehicle, motors that raise or lower windowpanes of the vehicle, and an occupancy sensor that senses whether an occupant is occupying the interior; and
the controller is configured to activate the ozone generator to generate ozone into the interior only when the locks of the doors are preventing access into the interior, the motors have fully raised the windowpanes, and the occupancy sensor indicates that no occupant is occupying the interior.

9. The vehicle of claim 6 further comprising:
a controller in communication with (i) at least one of the negative ion generator and the ultraviolet radiation source, and (ii) the motors connected to the rotating features;
a first row of seating; and
a second row of seating;
wherein, the controller is configured to manipulate the motors to cause the air sanitizing apparatus to move along the track system past the first row of seating and above the second row of seating, and cause the negative ion generator to negatively ionize molecules in the air of the interior of the vehicle and the ultraviolet radiation source to irradiate the air of the interior with ultraviolet radiation while the air sanitizing apparatus is positioned above the second row of seating.

10. The vehicle of claim 6 ,
the air sanitizing apparatus further comprises:
an air flow tube having an inside through which air can flow; and
an exhaust fan disposed at an end of the air flow tube and configured to cause air to flow through the inside of the air flow tube;
wherein, the ultraviolet radiation source is configured to irradiate ultraviolet radiation into the inside of the air flow tube.

11. The vehicle of claim 6 , wherein
the air sanitizing apparatus further comprises: (i) an air flow tube having an inside through which air can flow, and (ii) an exhaust fan disposed at an end of the air flow tube and configured to cause the air to flow through the inside of the air flow tube;
the ultraviolet radiation source is configured to irradiate ultraviolet radiation into the inside of the air flow tube; and
the air sanitizing apparatus further comprises another ultraviolet radiation source that, when activated, irradiates a surface of a seat with ultraviolet radiation.

12. The air sanitizing apparatus of claim 6 wherein the access panel is a removable vented access panel.

13. The vehicle of claim 6 , wherein
the track system comprises a first track and a second track;
the rotating feature of the first end portion of the air sanitizing apparatus extends outward from the first end portion and cooperates with the first track of the track system; and
the rotating feature of the second end portion of the air sanitizing apparatus extends outward from the second end portion and cooperates with the second track of the track system.

14. The vehicle of claim 6 , wherein
the track system comprises a first track and a second track;
the rotating feature of the first end portion of the air sanitizing apparatus extends into the first track of the track system; and
the rotating feature of the second end portion of the air sanitizing apparatus extends into the second track of the track system.

15. The vehicle of claim 6 , wherein
the track system comprises a first track and a second track;
the rotating feature of the first end portion of the air sanitizing apparatus extends onto the first track of the track system; and
the rotating feature of the second end portion of the air sanitizing apparatus extends onto the second track of the track system.
