FIG. 2illustrates a perspective lateral top view of the wand assembly102, according to an embodiment of the present disclosure. The sanitizing head106couples to the handle108through the coupler110. The sanitizing head106includes a shroud112having an outer cover114that extends from a proximal end116to a distal end118. As described herein, the shroud112contains a UV lamp.

Optionally, the wand assembly102may include the sanitizing head106connected to a fixed handle. Further, the wand assembly102may be sized and shaped differently than shown.

A port120extends from the proximal end116. The port120couples to a hose122, which, in turn, couples to the backpack assembly104(shown inFIG. 1). The hose122contains electrical cords, cables, wiring, or the like that couples a power source or supply (such as one or more batteries) within the backpack assembly104(shown inFIG. 1) to a UV lamp140within the shroud112. Optionally, the electrical cords, cables, wiring, or the like may be outside of the hose122. In at least one embodiment, the hose122also contains an air delivery line, such as an air tube) that fluidly couples an internal chamber of the shroud112to an air blower, vacuum generator, air filters, and/or the like within the backpack assembly104.

The coupler110is secured to the outer cover114of the shroud112, such as proximate to the proximal end116. The coupler110may include a securing beam124secured to the outer cover114, such as through one or more fasteners, adhesives, and/or the like. An extension beam126outwardly extends from the securing beam124, thereby spacing the handle108from the shroud112. A bearing assembly128extends from the extension beam126opposite from the securing beam124. The bearing assembly128includes one or more bearings, tracks, and/or the like, which allow the handle108to linearly translate relative to the coupler110in the directions of arrows A, and/or pivot about a pivot axle in the directions of arc B. Optionally, the securing beam124may include a bearing assembly that allows the sanitizing head106to translate in the directions of arrows A, and/or rotate (for example, swivel) in the directions of arc B in addition to, or in place of, the handle108being coupled to the bearing assembly128(for example, the handle108may be fixed to the coupler110).

In at least one other embodiment, the wand assembly102does not include the coupler110. Instead, the handle108may be fixed to the shroud112, for example.

In at least one embodiment, the handle108includes a rod, pole, beam, or the like130, which may be longer than the shroud112. Optionally, the rod130may be shorter than the shroud112. One or more grips132are secured to the rod130. The grips132are configured to be grasped and held by an individual. The grips132may include ergonomic tactile features134.

Optionally, the wand assembly102can be sized and shaped differently than shown. For example, in at least one example, the handle108can be fixed in relation to the shroud112. Further, the handle108may not be configured to move relative to itself and/or the shroud112. For example, the handle108and the shroud112can be integrally molded and formed as a single unit.

FIG. 3illustrates a perspective rear view of the wand assembly102ofFIG. 2.FIG. 4illustrates a perspective lateral view of the wand assembly102ofFIG. 2. Referring toFIGS. 3 and 4, the handle108may pivotally couple to the coupler110through a bearing136having a pivot axle138that pivotally couples the handle108to the coupler110. The handle108may further be configured to linearly translate into and out of the bearing136. For example, the handle108may be configured to telescope in and out. Optionally, or alternatively, in at least one embodiment, the handle108may include a telescoping body that allows the handle108to outwardly extend and inwardly recede. In at least one other embodiment, the handle108may not be configured to move, extend, retract, or the like relative to the shroud112.

FIG. 5illustrates a perspective view of the portable sanitizing system100in a compact deployed position, according to an embodiment of the present disclosure. The wand assembly102is removed from the backpack assembly104(as shown inFIG. 1) into the compact deployed position, as shown inFIG. 5. The hose122connects the wand assembly102to the backpack assembly104. In the compact deployed position, the sanitizing head106is fully retracted in relation to the handle108.

FIG. 6illustrates a perspective view of the portable sanitizing system100having the sanitizing head106in an extended position, according to an embodiment of the present disclosure. In order to extend the sanitizing head106relative to the handle108, the sanitizing head106is outwardly slid relative to the handle108in the direction of arrow A′ (or the handle108is rearwardly slid relative to the sanitizing head106). As noted, the sanitizing head106is able to linearly translate in the direction of arrow A′ relative to the handle108via the coupler110. The outward extension of the sanitizing head106, as shown inFIG. 6, allows for the portable sanitizing system100to easily reach distant areas. Alternatively, the sanitizing head106may not linearly translate relative to the handle108.

FIG. 7illustrates a perspective view of the portable sanitizing system100having the sanitizing head106in an extended position and the handle108in an extended position, according to an embodiment of the present disclosure. To reach even further, the handle108may be configured to linearly translate, such as through a telescoping portion, to allow the sanitizing head106to reach further outwardly. Alternatively, the handle108may not be configured to extend and retract.

In at least one embodiment, the handle108may include a lock109. The lock109is configured to be selectively operated to secure the handle108into a desired extended (or retracted) position.

FIG. 8illustrates a perspective view of the portable sanitizing system100having the sanitizing head106rotated in relation to the handle108, according to an embodiment of the present disclosure. As noted, the sanitizing head106is configured to rotate relative to the handle108via the coupler110. Rotating the sanitizing head106relative to the handle108allows the sanitizing head106to be moved to a desired position, and sweep or otherwise reach into areas that would otherwise be difficult to reach if the sanitizing head106was rigidly fixed to the handle108. Alternatively, the sanitizing head106may not be rotatable relative to the handle108.

FIG. 9illustrates a perspective end view of a UV lamp140and a reflector142of the sanitizing head106, according to an embodiment of the present disclosure. The UV lamp140and the reflector142are secured within the shroud112(shown inFIG. 2, for example) of the sanitizing head106. In at least one embodiment, the reflector142is secured to an underside141of the shroud112, such as through one or more adhesives. As another example, the reflector142is an integral part of the shroud112. For example, the reflector142may be or otherwise provide the underside141of the shroud112. The reflector142provides a reflective surface143(such as formed of Teflon, a mirrored surface, and/or the like) that is configured to outwardly reflect UV light emitted by the UV lamp140. In at least one example, shroud112may be or include a shell formed of fiberglass, and the reflector142may be formed of Teflon that provides a 98% reflectivity. In at least one embodiment, the reflector142may be a multi-piece reflector.

The reflector142may extend along an entire length of the underside141of the shroud112. Optionally, the reflector142may extend along less than an entire length of the underside141of the shroud112.

The UV lamp140may extend along an entire length (or along substantially the entire length, such as between the ends116and118). The UV lamp140is secured to the reflector142and/or the shroud112through one or more mounts, such as brackets, for example. The UV lamp140includes one or more UV light emitters, such as one more bulbs, light emitting elements (such as light emitting diodes), and/or the like. In at least one embodiment, the UV lamp140is configured to emit UV light in the far UV spectrum, such as at a wavelength between 200 nm-230 nm. In at least one embodiment, the UV lamp140is configured to emit UV light having a wavelength of 222 nm. For example, the UV lamp140may be or include a 300 W bulb that is configured to emit UV light having a wavelength of 222 nm. Optionally, the UV lamp140may be configured to emit UV light in other portions of the UV spectrum, such as the UVC spectrum. For example, the UV lamp140may be configured to emit UV light having a wavelength of 254 nm. In at least one other embodiment, the UV lamp140may be configured to emit UV light in portions of the UV spectrum other than the far UV spectrum, or the UVC spectrum.

As shown, the reflector142includes flat, upright side walls144connected together through an upper curved wall146. The upper curved wall146may be bowed outwardly away from the UV lamp140. For example, the upper curved wall146may have a parabolic cross-section and/or profile.

It has been found that the straight, linear side walls144provide desired reflection and/or focusing of UV light emitted from the UV lamp140toward and onto a desired location. Alternatively, the side walls144may not be linear and flat.

FIG. 10illustrates a perspective end view of the UV lamp140and a reflector142of the sanitizing head, according to an embodiment of the present disclosure. The reflector142shown inFIG. 10is similar to the reflector142shown inFIG. 9, except that the side walls144may outwardly cant from the upper curved wall146.

FIG. 11illustrates a perspective end view of the UV lamp140and the reflector142of the sanitizing head, according to an embodiment of the present disclosure. In this embodiment, the side walls144may be curved according to the curvature of the upper curved wall146.

FIG. 12illustrates a perspective top view of the sanitizing head106.FIG. 13illustrates a perspective bottom view of the sanitizing head106.FIG. 14illustrates an axial cross-sectional view of the sanitizing head106through line14-14ofFIG. 12. Referring toFIGS. 12-14, air150is configured to be drawn into the sanitizing head106through one or more openings152(or simply an open chamber) of the shroud112. The air150is drawn into the sanitizing head106, such as via a vacuum generator within the backpack assembly104(shown inFIG. 1). The air150is drawn into the shroud112, and cools the UV lamp140as it passes over and around the UV lamp140. The air150passes into the port120and into the hose122, such as within an air tube within the hose122. The air150not only cools the UV lamp140, but also removes ozone, which may be generated by operation of the UV lamp140, within the shroud112. The air150may be drawn to an air filter, such as an activated carbon filter, within the backpack assembly104.

In at least one embodiment, the portable sanitizing system100may also include an alternative ozone mitigation system. As an example, the ozone mitigation system may be disposed in the shroud112or another portion of the system, and may include an inert gas bath, or a face inert gas system, such as in U.S. Pat. No. 10,232,954.

Referring toFIG. 13, in particular, a bumper153may be secured to an exposed lower circumferential edge155of the shroud112. The bumper153may be formed of a resilient material, such as rubber, another elastomeric material, open or closed cell foam, and/or the like. The bumper153protects the sanitizing head106from damage in case the sanitizing head106inadvertently contacts a surface. The bumper153also protects the surface from damage.

The openings152may be spaced around the lower surface of the shroud112such that they do not provide a direct view of the UV lamp140. For example, the openings152may be positioned underneath portions that are spaced apart from the UV lamp140.

Referring toFIG. 14, in particular, the sanitizing head106may include a cover plate154below the UV lamp140. The cover plate154may be formed of glass, for example, and may be configured to filter UV light emitted by the UV lamp140. The UV lamp140may be secured within an interior chamber156defined between the reflector142and the cover plate154. In at least one embodiment, the cover plate154is or otherwise includes a far UV band pass filter. For example, the cover plate154may be a 222 nm band pass filter that filters UV light emitted by the UV lamp140to a 222 nm wavelength. As such, UV light that is emitted from the sanitizing head106may be emitted at a wavelength of 222 nm. As another example, the cover plate154may be a 254 nm band filter that filters UV light emitted by the UV lamp140to a 254 nm wavelength.

Referring toFIGS. 13 and 14, a rim157(such as a 0.020″ thick Titanium rim) may connect the cover plate154to the shroud112. The rim157may distribute impact loads therethrough and/or therearound.

In at least one embodiment, ranging light emitting diodes (LEDs)159may be disposed proximate to ends of the UV lamp140. The ranging LEDs159may be used to determine a desired range to a structure that is to be sanitized, for example. In at least one embodiment, the ranging LEDs159may be disposed on or within the rim157and/or the cover plate154. As another example, the sanitizing head106may be configured for range guidance, as disclosed in U.S. Provisional Application No. 63/027,869, which was filed May 20, 2020.

FIG. 15illustrates a perspective end view of the UV lamp140secured to a mounting bracket or clamp160, according to an embodiment of the present disclosure. Each end of the UV lamp140may be coupled to mounting bracket or clamp160, which secures the UV lamp140to the shroud112(shown inFIGS. 12-14). A buffer, such as a thin (for example, 0.040″) sheet of silicon may be disposed between the end of the UV lamp140and the bracket160. Optionally, the UV lamp140may be secured to the shroud112through brackets or clamps that differ in size and shape than shown. As another example, the UV lamp140may be secured to the shroud112through adhesives, fasteners, and/or the like.

FIG. 16illustrates a perspective exploded view of the backpack assembly104, according to an embodiment of the present disclosure. The backpack assembly104includes a front wall170that couples to a rear shell172, a base174, and a top cap176. An internal chamber178is defined between the front wall170, the rear shell172, the base174, and the top cap176. One or more batteries180, such as rechargeable Lithium batteries, are contained within the internal chamber178. An air generation sub-system182is also contained within the internal chamber178. The air generation sub-system182is in fluid communication with an air tube within the hose122(shown inFIG. 2, for example). The air generation sub-system182may include an airflow device, such as a vacuum generator, an air blower, and/or the like. The airflow device is configured to generate airflow to cool the UV lamp, draw air from the sanitizing head106into the backpack assembly104and out through an exhaust, draw or otherwise remove generated ozone away from the shroud112, and/or the like.

One or more air filters183, such as carbon filters, are within the backpack assembly104. The air filters183are in communication with the air tube or other such delivery duct or line that routes air through the hose122and into the backpack assembly104. The air filters183are configured to filter the air that is drawn into the backpack assembly104from the shroud112. For example, the air filters183may be configured to remove, deactivate, or otherwise neutralize ozone.

The batteries180and/or a power supply within the backpack assembly104provides operating power for the UV lamp140of the sanitizing head106(shown inFIG. 2, for example). The top wall176may be removably coupled to the front wall170and the rear shell172. The top wall176may be removed to provide access to the batteries180(such as to remove and/or recharge the batteries), for example. Additional space may be provided within the backpack assembly104for storage of supplies, additional batteries, additional components, and/or the like. In at least one embodiment, the front wall170, the rear shell172, the base174, and the top cap176may be formed of fiberglass epoxy.

FIG. 17illustrates a perspective front view of the harness105coupled to the backpack assembly104, according to an embodiment of the present disclosure. The harness105may include shoulder straps190and/or a waist or hip belt or strap192, which allow the individual to comfortably wear the backpack assembly104.

Referring toFIGS. 1-17, in operation, the individual may walk through an area wearing the backpack assembly104. When a structure to be sanitized is found, the individual may position grasp the handle108and position the sanitizing head106as desired, such as by extending and/or rotating the sanitizing head106relative to the handle108. The individual may then engage an activation button on the handle108, for example, to activate the UV lamp140to emit sanitizing UV light onto the structure. As the UV lamp140is activated, air150is drawn into the shroud112to cool the UV lamp140, and divert any generated ozone into the backpack assembly104, where it is filtered by the air filters183.

The extendable wand assembly102allows the sanitizing head106to reach distant areas, such as over an entire set of three passenger seats, from a row within an internal cabin of a commercial aircraft.

FIG. 18illustrates an ultraviolet light spectrum. Referring toFIGS. 1-18, in at least one embodiment, the sanitizing head106is configured to emit sanitizing UV light (through operation of the UV lamp140) within a far UV spectrum, such as between 200 nm to 230 nm. In at least one embodiment, the sanitizing head106emits sanitizing UV light having a wavelength of 222 nm. In at least one other embodiment, the sanitizing head106is configured to emit sanitizing UV light within the UVC spectrum, such as between 230 nm to 280 nm. For example, the sanitizing head106emits sanitizing UV light having a wavelength of 254 nm. In at least one other embodiment, the sanitizing head106is configured to emit sanitizing UV light within different portions of the UV spectrum.

FIG. 19illustrates a perspective view of a portable sanitizing system100, according to an embodiment of the present disclosure. The portable sanitizing system100includes a case assembly200that is configured to store the wand assembly102(hidden from view inFIG. 19) when the case assembly200is in a closed position, as shown inFIG. 19.

The case assembly200may be formed of plastic, for example. The case assembly200includes a main body201, such as a shell, lower body portion, or the like. A cover202, such as a lid, or upper body portion, is moveably coupled to the main body201. For example, the cover202may be coupled to the main body201through a hinge that allows the cover202to be opened and closed relative to the main body201.

The main body201includes a base204connected to a rear wall206, lateral walls208, and a top wall210. The cover202is moveably coupled to a first lateral wall208, such as through a hinge. One or more latches212are disposed on a second lateral wall208, opposite from the first lateral wall208. The latches212are configured to engage one or more reciprocal latch members213extending from the cover202to secure the cover202in the closed position. The latches212may be engaged by an individual to disengage the latch members213to allow the cover202to be pivoted into an open position.

A handle214is secured to the case assembly200. For example, the handle214is pivotally secured to a lateral wall208. The handle214is configured to be grasped by an individual so that the portable sanitizing system100may be carried. Optionally, the handle214may be secured to other portions of the case assembly200, such as the top wall210. In at least one embodiment, the handle214may be configured to retract into the case assembly200into a fully retracted position, and extend out of (for example, telescope out of) the case assembly200into a fully extended position.

Casters216or other such wheels may be rotatably secured to a portion of the case assembly200. For example, two casters216may be rotatably secured to the base204proximate to the rear wall206. An individual may tilt the case assembly200so that the casters216contact a floor. In this manner, the individual may roll the portable sanitizing system100via the casters216(and optionally through a handle in an extended position from the top wall210). Alternatively, the case assembly200may not include the casters216.

The hose122may outwardly extend from the case assembly200. In the closed position, when the wand assembly102is in a stowed position within the case assembly200, the hose122may be coiled over the cover202. A hose retainer218may secure the hose122in place on the cover202. For example, the hose retainer218may include a flexible fabric sheet220that is secured to a first side221of the cover202, and may removably secured to an opposite second side222of the cover202, such as through one or more fastening members224, such as hooks and loops, latches, clips, and/or the like. The hose retainer218is configured to secure the hose122on the cover202when the wand assembly102is within a storage chamber of the case assembly200and the cover202is in a closed position. Alternatively, the hose122may be contained within a storage chamber of the case assembly200when the wand assembly102is not in use. That is, the storage chamber may be sized and shaped to also contain the hose122when the wand assembly102is also within the storage chamber and the cover202is in the closed position.

The wand assembly102within the case assembly200in the closed position is protected from inadvertent engagement, bumping, and the like. That is, by storing the wand assembly102within the case assembly200, which is closed, when the wand assembly102is not in use, the portable sanitizing system100protects the wand assembly102from potential damage, and increases the useful life of the wand assembly102.

FIG. 20illustrates a perspective view of the portable sanitizing system100having the case assembly200in an open position, according to an embodiment of the present disclosure. As shown, the cover202is opened via a hinge226that pivotally couples the cover202to the main body201.

Various components of the portable sanitizing system100may be stored within the storage chamber228. For example, the components within the backpack assembly104, as described with respect toFIG. 16, may be contained within the storage chamber228.

For example, when not in use, the wand assembly102is contained within the storage chamber228. Additionally, one or more batteries, such as rechargeable Lithium batteries, may be contained within the storage chamber228.

An air generation sub-system (such as a cooling fan) may also be contained within the storage chamber228. The air generation sub-system may be in fluid communication with an air tube within the hose122. The hose122may be removably connected to the air generation sub-system. In at least one embodiment, the hose122is configured to be coupled to and uncoupled from the wand assembly102and the air generation sub-system. That is, the hose122may be removably coupled to the wand assembly102and the air generation sub-system.

One or more air filters, such as carbon filters, may also be within the storage chamber228. The air filters may be in communication with the air tube or other such delivery duct or line that routes air through the hose122.

FIG. 21illustrates a perspective view of the portable sanitizing system100having the case assembly200in the open position, according to an embodiment of the present disclosure. The wand assembly102is configured to be stowed in the storage chamber228. When the wand assembly102is to be used, the cover202is opened, and a first end230of the hose122is coupled to the port120of the wand assembly102. In at least one embodiment, the hose122is configured to channel cooling air into the wand assembly102, in order to cool the UV lamp140during activation.

A second end232of the hose122may be connected to a port234extending into and through a portion of the main body201, such as through a portion of the top wall210. The port234connects the hose122to an air generation sub-system, such as a cooling fan236that is within the storage chamber228. The cooling fan236may be activated to generate cooling air that is delivered to the wand assembly102through the hose122(such as an air tube within the hose122, or through an internal passage of the hose122itself).

One or more batteries180may also be stowed within the storage chamber228. For example, three batteries180may be within the storage chamber228.

A power supply238is also contained within the storage chamber228. The power supply238may be coupled to the wand assembly102through a power cord (such as via a plug and receptacle fitting) to provide power to the wand assembly102. Further, the power supply238may be configured to provide power to the batteries180(such as to recharge the batteries180). The batteries180may be secured to the wand assembly102and provide power to the wand assembly102, so that the wand assembly102may be used without connection to the power supply238.

The cooling fan236couples to the hose122via the port234. The cooling fan236may also include a diverter port that couples to an internal portion of the power supply238. In this manner, cooling air may be delivered to both the hose122(and therefore the wand assembly102), and the power supply238, thereby providing cooling to both the wand assembly102and the power supply238.

A hole240may be formed through a portion of the case assembly200. For example, a hole240may be formed through a portion of the top wall210and sized and shaped to allow the hose122to pass therethrough. In this manner, the hose122may remain connected to the wand assembly102even when the wand assembly102is contained within the storage chamber228and the cover202is closed. Other portions of the hose122between the first end230and the second end232may be secured to the cover202by the hose retainer218, as shown and described with respect toFIG. 19.

As shown, the handle214may be secured to the top wall210of the main body201. The handle214may be configured to retracted into and extend out of the main body201. For example, the handle214may be a telescoping handle.

The wand assembly102is removably secured within the storage chamber228. For example, the wand assembly102may be removably secured within the storage chamber228by one or more latches, clips, or via an interference fit with a conforming portion of the case assembly200.

The power supply238may be fixed in position within the storage chamber228. For example, the power supply238may be fixed in the storage chamber228by one or more fasteners, adhesives, or the like. Optionally, the power supply238may be secured in position by one or more latches, clips, or the like.

The batteries180may similarly be fixed position within the storage chamber228. For example, the batteries180may be fixed in the storage chamber228by one or more fasteners, adhesives, or the like. Optionally, the batteries180may be secured in position by one or more latches, clips, or the like. In at least one other embodiment, the batteries180may be removable, and configured to couple directly to the wand assembly102to provide power thereto.

FIG. 22illustrates a perspective view of the portable sanitizing system100having the case assembly200in the open position, according to an embodiment of the present disclosure. A power cord250may also be stowed within the storage chamber228. The power cord250is contained within the case assembly200when the cover202is closed and the portable sanitizing system100is moved when the wand assembly102is not being operated.

Optionally, the power cord250connects the power supply238to a source of power (such as a wall outlet). In addition to supply air to the wand assembly102, the hose122also routes electrical cables and the like to the wand assembly102from the power supply238and the batteries180.

Optionally, the hose122may not include electrical connections to the wand assembly102. Instead, the wand assembly102, the power cord250may plug into the wand assembly102, via the plug252, to supply power from the power supply238and/or the batteries180. In this embodiment, as the wand assembly102is operated, the plug252of the power cord250is connected to a reciprocal receptacle of the wand assembly102. An opposite end of the power cord250is connected to the power supply238(and/or, a battery180). The power cord250extends out of the case assembly200through the hole240. Thus, the wand assembly102may be removed from the storage chamber228and connected to the hose122and the power cord250, which extend through the hole240. The cover202may then be closed, thereby securely retaining the power supply238, the batteries180, and the like within the storage chamber228. The wand assembly102may then be activated, as it is powered via the power supply238or one or more of the batteries180, and the closed case assembly200may be moved, such as via an individual grasping the handle214and rolling the case assembly200via the casters216(shown inFIGS. 19 and 20).

Further, the hole240also allows intake air to be drawn into the storage chamber228, even when the cover202is closed over the main body201. Accordingly, the cooling fan236is able to receive fresh air, even when the cover202is closed.

The power supply238may be configured to receive power from a standard power supply, such as a source of alternating current power. For example, the power supply238may connect to the source of alternating current power through a power cord. The power cord250connects to the wand assembly102, and is configured to deliver power to the wand assembly102to operate the UV lamp140from power received from the power supply238and optionally the batteries180. For example, when the power supply238is connected to a source of alternating current power, the wand assembly102is powered by the power supply238. In the absence of such power, the wand assembly102may be powered by the batteries180. For example, the wand assembly102receives power from the batteries180the power supply238is not plugged into a power outlet. If the power supply238is plugged into a power outlet, one or more relays in the power supply238switch over from the batteries180to alternating current power supply from the power outlet.

FIG. 23illustrates a perspective lateral view of the wand assembly102, according to an embodiment of the present disclosure. As shown, the handle108may be fixed in relation to the shroud112. For example, the handle108may be integrally molded and formed with the shroud112. The wand assembly102may be small and compact in order to fit in confined spaced, such as within a flight deck of an aircraft.

An activation trigger260is moveably coupled to the handle108. For example, the activation trigger260may be secured to an underside262of a main beam264of the handle108. The activation trigger260is configured to be selectively pressed and/or depressed to activate and deactivate the UV lamp140of the wand assembly102, as desired.

The activation trigger260may be located anywhere along the length of the handle108. The activation trigger260may be shaped differently than shown. Further, the activation trigger260may be smaller or larger than shown. As an example, the activation trigger260may be a circular button, instead of an elongated bar or beam, as shown. Also, optionally, the activation trigger260may be located on a top portion of the main beam264, or on an extension beam266, which spaces the handle108from the shroud112. As another example, the activation trigger260may be located on a portion of the shroud112.

FIG. 24illustrates a perspective bottom view of the wand assembly102ofFIG. 23. As shown, the reflector142is secured to an underside of the shroud112.

FIG. 25illustrates a perspective bottom view of the wand assembly102ofFIGS. 23 and 24without the UV lamp140(for the sake of clarity), according to an embodiment of the present disclosure.FIG. 26illustrates a perspective view of a cooling manifold270of the shroud112of the wand assembly102. Referring toFIGS. 25 and 26, a half of the reflector142is removed to expose a cooling manifold270that extends through the shroud112and is in fluid communication with the port120. The cooling manifold270has a plurality of air outlets271that allow air delivered through the hose122(shown inFIG. 23, for example) that is coupled to the port120to pass over the UV lamp140when activated. In this manner, the UV lamp140is cooled during operation. The delivered air passes over and around the reflector142(which is disposed between the cooling manifold270and the UV lamp140), through a channel defined through the reflector142, and/or between two portions of the reflector142(such as a first half of the reflector142and a second half of the reflector142).

As shown, the cooling manifold270is formed in the shroud112. In at least one embodiment, the sanitizing head106including the shroud112is part of the wand assembly102of a portable sanitizing system. In at least one other embodiment, the sanitizing head106including the shroud112can be part of a permanent fixed sanitizing system. For example, the sanitizing head106including the shroud112can be part of a fixed and/or permanent sanitizing system within a lavatory, a galley or the like within an internal cabin of a vehicle, and/or within an enclosed space of a vehicle or fixed building, for example.

In at least one embodiment, a sanitizing system, such as the portable sanitizing system100, includes the wand assembly102. The wand assembly102includes the UV lamp140. The cooling manifold270is configured to allow air to blow across the UV lamp140, such as one or more bulbs of the UV lamp140. The wand assembly102may also include a two-piece reflector142, a master power switch, and a trigger switch, such as the activation trigger260, to activate and illuminate the UV lamp140.

During use of the wand assembly102, the case assembly200may be placed away from the area being disinfected, thereby allowing the operator to transport only the wand assembly102to the area, and facilitating movement and operation in tight or confined spaces. The wand assembly102may include a 300 watt, 222 nm UV lamp, optional ranging lights, the cooling manifold270running the length of the shroud112, the reflector142, mounts (such as brackets, clamps, fasteners, and/or the like) to secure the UV lamp140to the shroud112, a master power switch on the handle108, and the activation trigger260on the handle108that is configured to be engaged to selectively activate and deactivate the UV lamp140. The reflector142may be made out of Teflon or an aluminum sheet, which allows the reflector142to provide electromagnetic shielding. The UV lamp140may be attached to the shroud112with wire straps or bands, which may be positioned on top of Teflon tape and dry woven fiberglass that serve as a cushion between the strap and the glass bulb.

FIG. 27illustrates a perspective bottom view of a portion of a sanitizing system300, according to an embodiment of the present disclosure. The sanitizing system300includes the sanitizing head106. For example, the sanitizing head106includes the UV lamp140secured within the shroud112. In at least one embodiment, the sanitizing head106is part of a wand assembly, such as any of the wand assemblies described herein, and the sanitizing system300is a portable sanitizing system, such as any of the portable sanitizing systems described herein. The wand assembly can be coupled to a backpack assembly, a case assembly, a cart, and/or the like. In at least one other embodiment, the sanitizing head106is a fixture within an enclosed space. For example, the sanitizing head106can be fixed within an enclosed space, such as a lavatory, galley, or the like.

The UV lamp140includes one or more UV light emitters. The UV lamp140can be an integral structure. Optionally, the UV lamp140can include a plurality of UV modules.

The sanitizing system300includes a cooling manifold270, such as described with respect toFIGS. 25 and 26. The cooling manifold270is configured to deliver air302around the UV lamp140. The air302cools the UV lamp140as the UV lamp140emits UV light. Further, the cooling manifold270is also configured to direct air302out through the cooling manifold270to exhaust the air302and generated ozone through an exhaust, for example.

The cooling manifold270can be integrally formed with the shroud112. In at least one other embodiment, the cooling manifold270is coupled to the shroud112. The cooling manifold270can be disposed in various areas, such as within a lavatory, galley, flight deck, or various areas within a vehicle, fixed building, or the like.

FIG. 28illustrates a perspective bottom view of the shroud112, according to an embodiment of the present disclosure. As shown, the cooling manifold270is formed in the shroud112. The UV lamp140(not shown inFIG. 28) is secured below (or over) the cooling manifold270.

In at least one embodiment, the cooling manifold270includes a plurality of air outlets271. The air outlets271can be linearly aligned. For example, the cooling manifold270includes a linear array of rectangular air outlets271, such as slots. As another option, instead of a plurality of air outlets271, a single long air outlet271can be used.

The port120includes a channel304that is in fluid communication with the cooling manifold270. As noted, the port120is configured to couple to the hose122(shown inFIG. 2, for example). The hose122can be coupled to a backpack assembly, a cart, a case assembly, or the like that that includes a fan, blower, or the like. In at least one other embodiment, the hose122can be coupled to a fixed fan or blower, such as within an enclosed space.

Air is delivered to the cooling manifold270through the port120. The air radially passes around the UV lamp140. The port120may also allow air and ozone to be exhausted therethrough. The shroud112can also include exhaust ports that allow generated ozone to pass therethrough.

FIG. 29illustrates a perspective cross-sectional view of the cooling manifold270within the shroud112ofFIG. 28.FIG. 30illustrates a perspective cross-sectional view of directing slots320of the cooling manifold270, according to an embodiment of the present disclosure.FIG. 31illustrates a lateral internal view of the shroud112ofFIG. 28. Referring toFIGS. 28-31, the cooling manifold270includes a plenum306defined by walls308. The walls308can be part of the shroud112. As shown, the cooling manifold270is disposed over (or under, depending on the orientation) of an air delivery line312, which is, in turn, disposed over (or under, depending on the orientation) of the air outlets271.

The plenum306is in fluid communication with the channel304of the port120through a connecting conduit310, such as defined by walls308. The plenum306is disposed adjacent to an air delivery line312. The air delivery line312fluidly couples the plenum306to the air outlets271.

The air delivery line312includes the directing slots320. The directing slots320are defined by arcuate fins322. The arcuate fins322can be semi-circular in shape. A directing slot320is defined between two neighboring fins322. Each directing slot320fluidly couples to a respective air outlet271. The cooling manifold270may include more or less air outlets271and directing slots320than shown. Optionally, the air delivery line312may not include the directing slots320. Instead, the plenum306can be fluidly coupled to the air outlets271without the directing slots320.

In operation, cooling air330is supplied to the cooling manifold270through the channel304of the port120. The air330pass through the channel304, into the connecting conduit310, and into the plenum306. The air330is forced and/or otherwise directed via a fan or blower, for example. The air330within the plenum306then passes through the air delivery line312and out through the air outlets271around the UV lamp140to cool the UV lamp140.

The arcuate fins322provide curved, arcuate directing slots320that direct the forced air330around the UV lamp140. For example, the curved shape of the fins322provides an arcuate airflow around the UV lamp140, thereby providing effective and even cooling around the UV lamp140.

The directing slots320are sized, shaped, and configured to push air radially around the UV lamp140. The directing slots320help create a jet of airflow. The directing slots320provide vanes that can be turned at an angle (for example, the fins322can be angled) so that the air flows around the UV lamp140over a desired path, so as to provide uniform cooling and along the length of the bulb (as opposed to just pushing fan air along a side or end of the UV lamp140).

The forced air330cools the UV lamp140and passes through one or more openings332formed through the shroud112. In this manner, the forced air330forces any generated ozone within the shroud112out through the openings332, thereby ensuring that ozone concentration is low. As such, the cooling manifold270ensures that any ozone generated by operation of the UV lamp140is safely dispersed.

The cooling manifold270ensures that the air330is more uniformly distributed along the length of the UV lamp140. Accordingly, the cooling manifold270ensures effective and efficient cooling of the UV lamp140.

Referring again toFIG. 28, an exhaust port340can be formed in the shroud112. The exhaust port340can be at an opposite end of the shroud112from the port120. Additional exhaust ports340can be formed in the shroud112. The exhaust port340can be formed at various other areas of the shroud112. The exhaust port340is configured to allow air and ozone to be exhausted from the shroud112.

In at least one embodiment, an exhaust manifold342is formed around a periphery of the shroud112. The exhaust manifold342includes a plurality of exhaust ports340in fluid communication with an interior of the shroud112, such as through one or more ducts. The exhaust manifold342may be along both sides of the shroud112. The exhaust manifold342allows air and any generated ozone within the shroud112to be uniformly exhausted out of the shroud112.

Each exhaust port340can include a hood346having an open end348. An aperture350is formed through the open end348. The aperture350is in fluid communication with an exhaust duct, passage, or the like that is in fluid communication with the internal chamber of the shroud112. For example, each aperture350is in fluid communication with an opening352that is in fluid communication with the internal chamber113of the shroud112. Optionally, the shroud112may not include the exhaust manifold342and/or separate exhaust ports340.

The shroud112can further include a cover plate, such as the cover plate154described with respect toFIG. 14. In at least one other embodiment, the shroud112does not include a cover plate.

FIG. 32illustrates a schematic block diagram of the sanitizing system300coupled to a fan400and an ozone scrubber402, according to an embodiment of the present disclosure. In at least one embodiment, the sanitizing system300is distinct from the fan400and the ozone scrubber402. In at least one other embodiment, the sanitizing system300includes one or both of the fan400and/or the ozone scrubber402, such as within a backpack assembly, a case assembly, a cart, and/or the like.

The fan400is in fluid communication with the cooling manifold270(such as any of those described herein) through one or more conduits404, such as one or more hoses, one or more tubes, one or more ducts, and/or the like. The fan400produces airflow that generates forced air into the cooling manifold270, which cools the UV lamp140, as described herein. The sanitizing system300can also include an exhaust sub-system406, such as one or exhaust ports, an exhaust manifold, or the like, as described herein.

The air cools the UV lamp140, and is exhausted, along with any generated ozone, through the exhaust sub-system406. The exhaust sub-system406can, in turn, be in fluid communication with the ozone scrubber402, such as through one or more conduits408. The ozone scrubber402neutralizes, deactivates, and/or converts the ozone to air, for example. The scrubbed air can then be recirculated within an enclosed spacer, such as through an environmental control system, air conditioning system, and/or the like. Optionally, the sanitizing system300may not be coupled to the ozone scrubber402.

In at least one embodiment, the sanitizing system300can be used to sanitize components within an enclosed space, such as flight deck of an aircraft. For example, the sanitizing system300can include a wand assembly, as described herein. The sanitizing system300can be used to reduce or otherwise displace ozone concentration levels during use. For example, a backpack or case assembly of the sanitizing system300can be placed outside an enclosed space (such as the flight deck), which allows the fan400to draw in air. While using the wand assembly in the enclosed space (the door to the enclosed space can be slightly propped open due to the hose extending therethrough), the wand assembly exhausts the ozone via the exhaust sub-system406, while supplying cool air to the UV lamp140via the cooling manifold270. The exhaust sub-system406may push the exhausted air into the enclosed space, which is then naturally drawn through the opened door. Accordingly, the ozone is displaced and dispersed out of the enclosed space.

Referring toFIGS. 1-32, certain embodiments of the present disclosure provide a sanitizing system including a sanitizing head106. The sanitizing head106includes the UV lamp140. The cooling manifold270is configured to deliver air to the UV lamp140to cool the UV lamp140. In at least one embodiment, the sanitizing head106also includes the exhaust sub-system406that is configured to exhaust ozone from the sanitizing head106.
