Background Art

[0005] Background of the Disclosure Vehicles such as commercial aircraft are used to transport passengers between various locations. Currently, systems for disinfecting or sanitizing surfaces within an aircraft, for example, using ultraviolet (UV) light, are being developed. To disinfect the surfaces of a structure, known UV light sterilization methods irradiate the structure with a broad range of UVC light.

[0006] During operation, UV emitters are normally cooled. However, known fans may not cool UV emitters uniformly. Therefore, UV emitters may overheat. Furthermore, such overheated UV emitters can generate high ozone concentrations in a confined space. [Overview of the project]

[0007] There is a need for systems and methods to effectively and efficiently cool the UV emitters of UV lamps. Furthermore, there is a need for systems and methods to reduce the ozone generated during the operation of UV lamps.

[0008] With these needs in mind, certain embodiments of the present disclosure provide a disinfection system comprising a disinfection head having an ultraviolet (UV) lamp and a cooling manifold configured to supply air to the UV lamp.

[0011] For example, a cooling manifold includes one or more air outlets configured to allow air to pass over and around a UV lamp.

[0012] For example, the disinfection head includes a shroud. The cooling manifold is formed within the shroud.

[0013] In at least one embodiment, the disinfection system further includes a port having a channel that communicates with a cooling manifold and fluid.

[0014] As an example, a cooling manifold includes a plenum, a connecting conduit that fluidly connects the plenum to a channel, an air supply line that fluidly communicates with the plenum, and one or more air outlets that fluidly communicate with the air supply line.

[0015] In at least one embodiment, the cooling manifold includes one or more directional slots defined by one or more arcuate fins, and one or more air outlets fluidly coupled to one or more directional slots.

[0016] In at least one embodiment, the disinfection system also includes an exhaust subsystem. For example, the exhaust subsystem includes one or more exhaust ports formed in the shroud of the disinfection head.

[0017] Certain embodiments of the present disclosure provide a disinfection method comprising: operating an ultraviolet (UV) lamp in a disinfection head to emit UV light onto a component; and supplying air to the UV lamp by a cooling manifold. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0019] The above summary and the following detailed descriptions of specific embodiments will be better understood when read in conjunction with the accompanying drawings. Furthermore, the reference to “one embodiment” is not intended to be construed as excluding the existence of additional embodiments that similarly encompass the features described. Furthermore, unless expressly stated otherwise, an embodiment “comprising” or “having” one or more elements having certain conditions may include additional elements that do not have such conditions.

[0020] In at least one embodiment, the disinfection system includes a UV lamp. The UV lamp may be part of a wand assembly, such as a portable disinfection system. The wand assembly may be coupled to a backpack assembly, case assembly, cart assembly, etc. In at least one other embodiment, the wand assembly is not coupled to a backpack assembly, case assembly, or cart assembly. In at least one other embodiment, the UV lamp may be fixed in place. A cooling manifold is configured to blow air across one or more UV emitters (such as bulbs) of the UV lamp.

[0021] In at least one embodiment, the disinfection system includes a feature for cooling electronic equipment and one or more UV emitters, such as a UV bulb. Furthermore, the disinfection system may also be configured to replace the UV lamp with generated ozone, for example.

[0022] In at least one embodiment, the cooling manifold is configured to supply radially cool, sprayed air around the UV lamp. The UV lamp and cooling manifold can be part of a wand assembly. In at least one other embodiment, the UV lamp and cooling manifold can be permanently fixed within an environment, such as inside the cabin of a vehicle.

[0023] Figure 1 shows a perspective view of a portable disinfection system 100 worn by an individual 101 according to one embodiment of the present disclosure. The portable disinfection system 100 includes a wand assembly 102 coupled to a backpack assembly 104 which is detachably secured to the individual via a harness 105. The wand assembly 102 includes a disinfection head 106 coupled to a handle 108. In at least one embodiment, the disinfection head 106 is movably coupled to the handle 108 via a coupler 110.

[0024] In at least one other embodiment, the portable disinfection system 100 does not have to be worn by an individual 101. For example, the portable disinfection system 100 may include a case assembly configured to open and close. The case assembly can store the wand assembly 102 when not in use. The case assembly can be opened to allow the wand assembly 102 to be removed and operated. In at least one other embodiment, the portable disinfection system 100 may include a movable cart assembly.

[0025] As shown in Figure 1, the wand assembly 102 is in the stowed position. In the stowed position, the wand assembly 102 is detachably secured to a part of the backpack assembly 104 via one or more tracks, clips, latches, belts, ties, etc.

[0026] In at least one other embodiment, the wand assembly 102 is stored within a case assembly in a storage position. For example, the wand assembly 102 in the storage position is contained within a closed case assembly. The case assembly can be opened to allow the wand assembly 102 to be removed and unfolded.

[0027] Figure 2 shows a perspective side top view of a wand assembly 102 according to one embodiment of the present disclosure. The disinfection head 106 is coupled to the handle 108 via a coupler 110. The disinfection head 106 includes a shroud 112 having an outer cover 114 extending from a proximal end 116 to a distal end 118. As described herein, the shroud 112 includes a UV lamp.

[0028] Optionally, the wand assembly 102 may include a disinfection head 106 connected to a fixed handle. Furthermore, the wand assembly 102 may be of a different size and shape than those shown.

[0029] Port 120 extends from the proximal end 116. Port 120 is connected to hose 122, which in turn connects to the backpack assembly 104 (shown in Figure 1). Hose 122 includes electrical cords, cables, wiring, etc., connecting a power source or power supply (such as one or more batteries) in the backpack assembly 104 (shown in Figure 1) to the UV lamp 140 in the shroud 112. Optionally, the electrical cords, cables, wiring, etc., may be located outside hose 122. In at least one embodiment, hose 122 also includes an air supply line, such as an air tube, which fluidly connects the internal chamber of the shroud 112 to a blower, vacuum generator, air filter, etc., in the backpack assembly 104.

[0030] The coupler 110 is fixed to the outer cover 114 of the shroud 112, such as near the proximal end 116. The coupler 110 may include a fixed beam 124 fixed to the outer cover 114, such as via one or more fasteners, adhesive, etc. An extension beam 126 extends outward from the fixed beam 124, thereby spacing the handle 108 away from the shroud 112. A bearing assembly 128 extends from the extension beam 126 on the opposite side of the fixed beam 124. The bearing assembly 128 includes one or more bearings, tracks, etc., so that the handle 108 can translate linearly relative to the coupler 110 in the direction of arrow A and / or pivotally rotate about the pivot axle in the direction of arc B. Optionally, the fixed beam 124 includes a bearing assembly that allows the disinfection head 106 to translate in the direction of arrow A, and / or, in addition to or instead, to rotate (e.g., rotate on a swivel) in the direction of arc B, and the handle 108 is coupled to the bearing assembly 128 (e.g., the handle 108 may be fixed to the coupler 110).

[0031] In at least one other embodiment, the wand assembly 102 does not include the coupler 110. Instead, the handle 108 may be attached to, for example, the shroud 112.

[0032] In at least one embodiment, the handle 108 includes a rod, pole, beam, etc. 130, which may be longer than the shroud 112. Optionally, the rod 130 may be shorter than the shroud 112. One or more grips 132 are fixed to the rod 130. The grips 132 are configured to be grasped and held by an individual. The grips 132 may include ergonomic tactile features 134.

[0033] Optionally, the wand assembly 102 may be of a different size and shape than those shown. For example, in at least one example, the handle 108 may be fixed to the shroud 112. Furthermore, the handle 108 may not be configured to move on its own and / or relative to the shroud 112. For example, the handle 108 and the shroud 112 may be molded integrally and formed as a single unit.

[0034] Figure 3 shows a perspective rear view of the wand assembly 102 of Figure 2. Figure 4 shows a perspective side view of the wand assembly 102 of Figure 2. Referring to Figures 3 and 4, the handle 108 can be pivotally coupled to the coupler 110 via a bearing 136 having a pivot 138 that pivotally connects the handle 108 to the coupler 110. The handle 108 may further be configured to move linearly in and out of the bearing 136. For example, the handle 108 may be configured to extend and retract telescopely. Optionally, or instead, in at least one embodiment, the handle 108 may include a telescopic body that allows the handle 108 to extend outward and retract inward. In at least one other embodiment, the handle 108 may not be configured to move, extend, retract, etc. relative to the shroud 112.

[0035] Figure 5 shows a perspective view of a portable disinfection system 100 in a compactly deployed position according to one embodiment of the present disclosure. The wand assembly 102 is detached from the backpack assembly 104 (as shown in Figure 1) to the compactly deployed position as shown in Figure 5. The hose 122 connects the wand assembly 102 to the backpack assembly 104. In the compactly deployed position, the disinfection head 106 is fully retracted relative to the handle 108.

[0036] Figure 6 shows a perspective view of a portable disinfection system 100 having a disinfection head 106 in an extended position according to one embodiment of the present disclosure. To extend the disinfection head 106 relative to the handle 108, the disinfection head 106 is slid outward relative to the handle 108 in the direction of arrow A' (or the handle 108 is slid backward relative to the disinfection head 106). As described above, the disinfection head 106 can be linearly translated relative to the handle 108 in the direction of arrow A' via the coupler 110. As shown in Figure 6, the outward extension of the disinfection head 106 allows the portable disinfection system 100 to easily reach distant areas. Alternatively, the disinfection head 106 does not have to be linearly translated relative to the handle 108.

[0037] Figure 7 shows a perspective view of a portable disinfection system 100 according to one embodiment of the present disclosure, having a disinfection head 106 in an extended position and a handle 108 in an extended position. To reach further, the handle 108 may be configured to translate linearly, such as through a telescoping portion, so that the disinfection head 106 can reach further outwards. Alternatively, the handle 108 may not be configured to extend and retract.

[0038] In at least one embodiment, the handle 108 may include a lock 109, which is configured to be selectively operated to lock the handle 108 in a desired extended (or retracted) position.

[0039] Figure 8 shows a perspective view of a portable disinfection system 100 having a disinfection head 106 rotated relative to a handle 108, according to one embodiment of the present disclosure. As previously stated, the disinfection head 106 is configured to rotate relative to the handle 108 via a coupler 110. By rotating the disinfection head 106 relative to the handle 108, the disinfection head 106 can be moved to a desired position and can be swept or otherwise reached into areas that would be difficult to reach if the disinfection head 106 were firmly fixed to the handle 108. Alternatively, the disinfection head 106 should not be rotatable relative to the handle 108.

[0040] Figure 9 shows a perspective end view of a UV lamp 140 and reflector 142 of a disinfection head 106 according to one embodiment of the present disclosure. The UV lamp 140 and reflector 142 are fixed within a shroud 112 of the disinfection head 106 (for example, shown in Figure 2). In at least one embodiment, the reflector 142 is fixed to the underside 141 of the shroud 112 via one or more adhesives, etc. In another example, the reflector 142 is an integral part of the shroud 112. For example, the reflector 142 may provide, or otherwise, the underside 141 of the shroud 112. The reflector 142 provides a reflective surface 143 (such as one formed of Teflon, a mirror, etc.) configured to reflect outward the UV light emitted by the UV lamp 140. In at least one example, the shroud 112 may be or include a shell formed of glass fiber, and the reflector 142 may be formed of Teflon providing a reflectivity of 98%. In at least one embodiment, the reflector 142 may be a multi-piece reflector.

[0041] The reflector 142 can extend along the entire length of the lower part 141 of the shroud 112. Optionally, the reflector 142 can extend along a length shorter than the entire length of the lower part 141 of the shroud 112.

[0042] The UV lamp 140 can extend along its entire length (or substantially along its entire length, such as between ends 116 and 118). The UV lamp 140 is fixed to the reflector 142 and / or shroud 112 via one or more mounts, such as a bracket. The UV lamp 140 includes one or more UV emitters, such as one or more bulbs, light-emitting elements (such as light-emitting diodes). In at least one embodiment, the UV lamp 140 is configured to emit UV light in the far-ultraviolet spectrum, such as wavelengths between 200 nm and 230 nm. In at least one embodiment, the UV lamp 140 is configured to emit UV light having a wavelength of 222 nm. For example, the UV lamp 140 may be or include a 300 W bulb configured to emit UV light having a wavelength of 222 nm. Optionally, the UV lamp 140 may be configured to emit UV light in other parts of the UV spectrum, such as the UVC spectrum. For example, the UV lamp 140 may be configured to emit UV light having a wavelength of 254 nm. In at least one other embodiment, the UV lamp 140 may be configured to emit UV light in a portion of the UV spectrum other than the far-ultraviolet spectrum or the UVC spectrum.

[0043] As shown, the reflector 142 includes flat, upright side walls 144 connected to each other via an upper curved wall 146. The upper curved wall 146 can be bent outward away from the UV lamp 140. For example, the upper curved wall 146 may have a parabolic cross-section and / or profile.

[0044] It has been found that the straight, linear sidewall 144 provides the desired reflection and / or focus of UV light emitted from the UV lamp 140 toward a desired position and at the desired position. Alternatively, the sidewall 144 does not have to be linear and flat.

[0045] Figure 10 shows a perspective end view of a UV lamp 140 and reflector 142 of a disinfection head according to one embodiment of the present disclosure. The reflector 142 shown in Figure 10 is similar to the reflector 142 shown in Figure 9, except that the side wall 144 may be inclined outward from the upper curved wall 146.

[0046] Figure 11 shows a perspective end view of a UV lamp 140 and reflector 142 of a disinfection head according to one embodiment of the present disclosure. In this embodiment, the side wall 144 can be curved according to the curvature of the upper curved wall 146.

[0047] Figure 12 shows a perspective top view of the disinfection head 106. Figure 13 shows a perspective bottom view of the disinfection head 106. Figure 14 shows an axial cross-sectional view of the disinfection head 106 through line 14-14 in Figure 12. Referring to Figures 12-14, air 150 is configured to be drawn into the disinfection head 106 through one or more openings 152 (or simply an open chamber) in the shroud 112. The air 150 is drawn into the disinfection head 106, for example, through a vacuum generator in the backpack assembly 104 (shown in Figure 1). The air 150 is drawn into the shroud 112 and cools the UV lamp 140 as it passes over and around the UV lamp 140. The air 150 enters the port 120 and the hose 122, for example, through an air tube in the hose 122. The air 150 not only cools the UV lamp 140 but also removes ozone that may be generated by the operation of the UV lamp 140 within the shroud 112. The air 150 can be drawn into an air filter, such as an activated carbon filter, within the backpack assembly 104.

[0048] In at least one embodiment, the portable disinfection system 100 may also include an alternative ozone reduction system. For example, the ozone reduction system may be located in the shroud 112 or another part of the system and may include an inert gas bath or a surface inert gas system such as in U.S. Patent No. 10,232,954.

[0049] In particular, referring to Figure 13, the bumper 153 can be fixed to the exposed lower circumferential edge 155 of the shroud 112. The bumper 153 can be formed from an elastic material such as rubber, another elastomer material, or open-cell or closed-cell foam. The bumper 153 protects the disinfecting head 106 from damage in the event that the disinfecting head 106 accidentally comes into contact with a surface. The bumper 153 also protects the surface from damage.

[0050] The opening 152 can be spaced around the underside of the shroud 112 so as not to provide a direct view of the UV lamp 140. For example, the opening 152 may be positioned below the portion spaced away from the UV lamp 140.

[0051] Referring in particular to Figure 14, the disinfection head 106 may include a cover plate 154 beneath the UV lamp 140. The cover plate 154 can be formed of, for example, glass and configured to filter the UV light emitted by the UV lamp 140. The UV lamp 140 may be fixed within an internal chamber 156 defined between a reflector 142 and the cover plate 154. In at least one embodiment, the cover plate 154 is or otherwise includes a far-ultraviolet bandpass filter. For example, the cover plate 154 may be a 222nm bandpass filter that filters the UV light emitted by the UV lamp 140 to a wavelength of 222nm. Thus, the UV light emitted from the disinfection head 106 may be emitted at a wavelength of 222nm. As another example, the cover plate 154 may be a 254nm bandfilter that filters the UV light emitted by the UV lamp 140 to a wavelength of 254nm.

[0052] Referring to Figures 13 and 14, the rim 157 (for example, a titanium rim with a thickness of 0.020 inches) can connect the cover plate 154 to the shroud 112. The rim 157 can distribute impact loads through it and / or around it.

[0053] In at least one embodiment, the range-measuring light-emitting diode (LED) 159 may be positioned near the end of the UV lamp 140. The range-measuring LED 159 may be used, for example, to determine a desired range to a structure to be disinfected. In at least one embodiment, the range-measuring LED 159 may be positioned on or inside the rim 157 and / or cover plate 154. As another example, the disinfection head 106 may be configured for range guidance, as disclosed in U.S. Provisional Application No. 63 / 027,869 filed May 20, 2020.

[0054] Figure 15 shows a perspective end view of a UV lamp 140 fixed to a mounting bracket or clamp 160 according to one embodiment of the present disclosure. Each end of the UV lamp 140 can be coupled to a mounting bracket or clamp 160 that secures the UV lamp 140 to a shroud 112 (as shown in Figures 12 to 14). A cushioning material, such as a thin (e.g., 0.040 inch) sheet of silicone, can be placed between the ends of the UV lamp 140 and the bracket 160. Optionally, the UV lamp 140 may be fixed to the shroud 112 via a bracket or clamp of a different size and shape than those shown. As another example, the UV lamp 140 may be fixed to the shroud 112 via adhesive, fasteners, etc.

[0055] Figure 16 shows an exploded perspective view of a backpack assembly 104 according to one embodiment of the present disclosure. The backpack assembly 104 includes a front wall 170 coupled to a rear shell 172, a base 174, and a top cap 176. An internal chamber 178 is defined between the front wall 170, the rear shell 172, the base 174, and the top cap 176. One or more batteries 180, such as a rechargeable lithium battery, are contained within the internal chamber 178. An air generation subsystem 182 is also contained within the internal chamber 178. The air generation subsystem 182 is in fluid communication with an air tube in a hose 122 (as shown, for example, in Figure 2). The air generation subsystem 182 may include airflow devices such as a vacuum generator or a blower. The airflow device is configured to generate an airflow for cooling the UV lamp, draw air from the disinfection head 106 into the backpack assembly 104, and exhaust it through the exhaust, drawing out the generated ozone from the shroud 112 or removing it in any other way.

[0056] One or more air filters 183, such as carbon filters, are located within the backpack assembly 104. The air filters 183 communicate with an air tube or other such supply duct or line that supplies air into the backpack assembly 104 via a hose 122. The air filters 183 are configured to filter the air drawn into the backpack assembly 104 from the shroud 112. For example, the air filters 183 may be configured to remove, deactivate, or otherwise neutralize ozone.

[0057] The battery 180 and / or the power source within the backpack assembly 104 provides operating power to the UV lamp 140 of the disinfection head 106 (as shown, for example, in Figure 2). The top wall 176 can be detachably coupled to the front wall 170 and the rear shell 172. The top wall 176 can be removed, for example, to provide access to the battery 180 (for example, to remove and / or recharge the battery). Additional space can be provided within the backpack assembly 104 for storing consumables, additional batteries, additional components, etc. In at least one embodiment, the front wall 170, the rear shell 172, the base 174, and the top cap 176 may be formed of glass fiber epoxy.

[0058] Figure 17 shows a perspective front view of a harness 105 coupled to a backpack assembly 104 according to one embodiment of the present disclosure. The harness 105 may include shoulder straps 190 and / or a waist or hip belt or strap 192, thereby allowing the individual to comfortably wear the backpack assembly 104.

[0059] Referring to Figures 1 to 17, during operation, the individual can pass through the area wearing the backpack assembly 104. When a structure to be disinfected is found, the individual can grasp the handle 108 and position the disinfection head 106 as needed, for example by extending and / or rotating the disinfection head 106 relative to the handle 108. The individual can then engage the activation button on the handle 108 to activate, for example, the UV lamp 140 and emit disinfection UV light onto the structure. When the UV lamp 140 is activated, air 150 is drawn into the shroud 112 to cool the UV lamp 140 and divert the generated ozone to the backpack assembly 104, where it is filtered by the air filter 183.

[0060] The extendable wand assembly 102 allows the disinfection head 106 to reach distant areas, such as an entire set of three passenger seats, from a row inside the cabin of a civilian aircraft.

[0061] Figure 18 shows the ultraviolet spectrum. Referring to Figures 1 to 18, in at least one embodiment, the disinfection head 106 is configured to emit disinfection UV light in the far-ultraviolet spectrum, such as between 200 nm and 230 nm (by the operation of the UV lamp 140). In at least one embodiment, the disinfection head 106 emits disinfection UV light having a wavelength of 222 nm. In at least one other embodiment, the disinfection head 106 is configured to emit disinfection UV light in the UVC spectrum, such as between 230 nm and 280 nm. For example, the disinfection head 106 emits disinfection UV light with a wavelength of 254 nm. In at least one other embodiment, the disinfection head 106 is configured to emit disinfection UV light in different parts of the UV spectrum.

[0062] Figure 19 shows a perspective view of a portable disinfection system 100 according to one embodiment of the present disclosure. The portable disinfection system 100 includes a case assembly 200 configured to house a wand assembly 102 (not visible in the view of Figure 19) when the case assembly 200 is in the closed position, as shown in Figure 19.

[0063] The case assembly 200 may be formed of, for example, plastic. The case assembly 200 includes a body 201, such as a shell or a lower body portion. A cover 202, such as a lid or an upper body portion, is movably attached to the body 201. For example, the cover 202 may be attached to the body 201 via a hinge that allows the cover 202 to open and close relative to the body 201.

[0064] The main body 201 includes a rear wall 206, a side wall 208, and a base 204 connected to the top wall 210. The cover 202 is movably coupled to the first side wall 208, for example, via a hinge. One or more latches 212 are located on the second side wall 208 opposite to the first side wall 208. The latches 212 are configured to engage with one or more mutual latch members 213 extending from the cover 202 to secure the cover 202 in the closed position. The latches 212 can be engaged by an individual to release the latch members 213 in order to allow the cover 202 to pivot to the open position.

[0065] The handle 214 is fixed to the case assembly 200. For example, the handle 214 is pivotally fixed to the side wall 208. The handle 214 is configured to be grasped by an individual so that the portable disinfection system 100 can be carried. Optionally, the handle 214 may be fixed to other parts of the case assembly 200, such as the top wall 210. In at least one embodiment, the handle 214 may be configured to be stored within the case assembly 200 in a fully retracted position and to extend from the case assembly 200 (e.g., telescope out) in a fully extended position.

[0066] Casters 216 or other such wheels may be rotatably fixed to a portion of the case assembly 200. For example, two casters 216 may be rotatably fixed to a base 204 adjacent to the rear wall 206. An individual can tilt the case assembly 200 so that the casters 216 are in contact with the floor. In this way, an individual can roll the portable disinfection system 100 via the casters 216 (and optionally via a handle positioned extending from the top wall 210). Alternatively, the case assembly 200 may not include casters 216.

[0067] The hose 122 can be extended outward from the case assembly 200. In the closed position, when the wand assembly 102 is in the storage position within the case assembly 200, the hose 122 can be coiled over the cover 202. A hose retainer 218 can secure the hose 122 in place on the cover 202. For example, the hose retainer 218 may include a flexible fabric sheet 220 that can be fixed to a first side 221 of the cover 202 and detachably fixed to a second side 222 on the opposite side of the cover 202, such as via one or more fastening members 224, such as hooks and loops, latches, or clips. The hose retainer 218 is configured to secure the hose 122 to the cover 202 when the wand assembly 102 is in the storage chamber of the case assembly 200 and the cover 202 is in the closed position. Alternatively, when the wand assembly 102 is not in use, the hose 122 may be contained within the storage chamber of the case assembly 200. That is, the storage chamber can be sized and shaped to accommodate the hose 122 when both the wand assembly 102 and the cover 202 are in the closed position.

[0068] The wand assembly 102 within the case assembly 200 in the closed position is protected from accidental engagement, collision, etc. In other words, by storing the wand assembly 102 within the closed case assembly 200, the portable disinfection system 100 protects the wand assembly 102 from potential damage when the wand assembly 102 is not in use, and extends the service life of the wand assembly 102.

[0069] Figure 20 shows a perspective view of a portable disinfection system 100 having a case assembly 200 in the open position according to one embodiment of the present disclosure. As shown, the cover 202 is opened via a hinge 226 that pivotally connects the cover 202 to the body 201.

[0070] The interior or storage chamber 228 is defined between the base 204, the side wall 208, the rear wall 206, and the top wall 210 (and the cover 202 if closed). Various components of the portable disinfection system 100 can be stored within the storage chamber 228. For example, as described with respect to Figure 16, components within the backpack assembly 104 can be contained within the storage chamber 228.

[0071] For example, when not in use, the wand assembly 102 is contained within the storage chamber 228. Furthermore, one or more batteries, such as a rechargeable lithium battery, may be contained within the storage chamber 228.

[0072] An air generation subsystem (such as a cooling fan) may also be included within the storage chamber 228. The air generation subsystem may be in fluid communication with an air pipe in the hose 122. The hose 122 can be detachably connected to the air generation subsystem. In at least one embodiment, the hose 122 is configured to be coupled to and detached from the wand assembly 102 and the air generation subsystem. That is, the hose 122 can be detachably coupled to the wand assembly 102 and the air generation subsystem.

[0073] One or more air filters, such as carbon filters, may also be located within the storage chamber 228. The air filters may be in communication with other such supply ducts or lines that carry air through air tubes or hoses 122.

[0074] Figure 21 shows a perspective view of a portable disinfection system 100 having a case assembly 200 in the open position according to one embodiment of the present disclosure. A wand assembly 102 is configured to be housed in a storage chamber 228. When the wand assembly 102 is in use, the cover 202 is opened and the first end 230 of the hose 122 is coupled to the port 120 of the wand assembly 102. In at least one embodiment, the hose 122 is configured to direct cooling air to the wand assembly 102 in order to cool the UV lamp 140 during startup.

[0075] The second end 232 of the hose 122 can be connected to a port 234 that extends through and into a part of the main body 201, such as through a part of the upper wall 210. The port 234 connects the hose 122 to an air generation subsystem, such as a cooling fan 236 located in the storage chamber 228. The cooling fan 236 can be activated to generate cooling air that is supplied to the wand assembly 102 via the hose 122 (such as through the air tube inside the hose 122 or through the internal passage of the hose 122 itself).

[0076] One or more batteries 180 can also be housed in the storage chamber 228. For example, three batteries 180 may be housed in the storage chamber 228.

[0077] The power supply 238 is also contained within the storage chamber 228. The power supply 238 can be coupled to the wand assembly 102 via a power cord (via a plug and receptacle fittings, etc.) to supply power to the wand assembly 102. Furthermore, the power supply 238 may be configured to supply power to the battery 180 (for example, to recharge the battery 180). The battery 180 can be fixed to the wand assembly 102 and supply power to the wand assembly 102, and as a result, the wand assembly 102 can be used without being connected to the power supply 238.

[0078] The cooling fan 236 is coupled to the hose 122 via port 234. The cooling fan 236 may also include a diverter port coupled to an internal part of the power supply 238. In this way, cooling air can be supplied to both the hose 122 (and thus the wand assembly 102) and the power supply 238, thereby providing cooling to both the wand assembly 102 and the power supply 238.

[0079] The hole 240 can be formed through a portion of the case assembly 200. For example, the hole 240 can be formed through a portion of the upper wall 210 and can be sized and shaped to allow the hose 122 to pass through it. In this way, the hose 122 may remain connected to the wand assembly 102 even when the wand assembly 102 is contained within the storage chamber 228 and the cover 202 is closed. As shown and described with respect to Figure 19, the other portion of the hose 122 between the first end 230 and the second end 232 can be secured to the cover 202 by a hose retainer 218.

[0080] As shown in the figure, the handle 214 can be fixed to the upper wall 210 of the main body 201. The handle 214 may be configured to be retracted into the main body 201 and to extend from the main body 201. For example, the handle 214 may be a telescopic handle.

[0081] The wand assembly 102 is removably secured within the storage chamber 228. For example, the wand assembly 102 may be removably secured within the storage chamber 228 by one or more latches, clips, or by a press-fit with a matching portion of the case assembly 200.

[0082] The power supply 238 can be fixed in place within the storage chamber 228. For example, the power supply 238 can be fixed to the storage chamber 228 by one or more fasteners, adhesives, etc. Optionally, the power supply 238 can be fixed in place by one or more latches, clips, etc.

[0083] The battery 180 may also be in a fixed position within the storage chamber 228. For example, the battery 180 may be secured to the storage chamber 228 by one or more fasteners, adhesives, etc. Optionally, the battery 180 may be secured in place by one or more latches, clips, etc. In at least one other embodiment, the battery 180 may be removable and configured to be directly coupled to the wand assembly 102 to supply power to it.

[0084] Figure 22 shows a perspective view of a portable disinfection system 100 having a case assembly 200 in the open position according to one embodiment of the present disclosure. A power cord 250 may also be housed in a storage chamber 228. The power cord 250 is contained within the case assembly 200 when the cover 202 is closed, and the portable disinfection system 100 is moved when the wand assembly 102 is not being operated.

[0085] Optionally, the power cord 250 connects the power supply 238 to a power source (such as a wall outlet). In addition to supplying air to the wand assembly 102, the hose 122 also wires electrical cables, etc., from the power supply 238 and battery 180 to the wand assembly 102.

[0086] Optionally, the hose 122 does not have to include an electrical connection to the wand assembly 102. Instead, the wand assembly 102 and power cord 250 can be plugged into the wand assembly 102 via plug 252 to be powered from the power supply 238 and / or battery 180. In this embodiment, when the wand assembly 102 is operated, the plug 252 of the power cord 250 connects to the receptacle of the wand assembly 102. The other end of the power cord 250 is connected to the power supply 238 (and / or battery 180). The power cord 250 extends from the case assembly 200 through hole 240. Thus, the wand assembly 102 can be removed from the storage chamber 228 and connected to the hose 122 and power cord 250 extending through hole 240. The cover 202 can then be closed to securely hold the power supply 238, battery 180, etc., inside the storage chamber 228. Next, the wand assembly 102 can be powered via the power supply 238 or one or more batteries 180, and the closed case assembly 200 can be moved, for example, by an individual gripping the handle 214 and rolling the case assembly 200 via the casters 216 (shown in Figures 19 and 20).

[0087] Furthermore, the holes 240 also allow intake air to be drawn into the storage chamber 228 even when the cover 202 is closed over the main body 201. Thus, the cooling fan 236 can receive fresh air even when the cover 202 is closed.

[0088] The power supply 238 can be configured to receive power from a standard power source, such as an AC power supply. For example, the power supply 238 can be connected to an AC power source via a power cord. The power cord 250 is connected to the wand assembly 102 and is configured to supply power to the wand assembly 102 so that the UV lamp 140 can be operated by power received from the power supply 238 and optionally from the battery 180. For example, if the power supply 238 is connected to an AC power source, the wand assembly 102 is powered by the power supply 238. If such power is unavailable, the wand assembly 102 may be powered by the battery 180. For example, the wand assembly 102 receives power from the battery 180 and the power supply 238 is not plugged into a power outlet. If the power supply 238 is plugged into a power outlet, one or more relays in the power supply 238 switch from the battery 180 to the AC power from the power outlet.

[0089] Figure 23 shows a perspective side view of a wand assembly 102 according to one embodiment of the present disclosure. As shown, the handle 108 can be fixed to the shroud 112. For example, the handle 108 can be molded and formed integrally with the shroud 112. The wand assembly 102 can be small and compact so as to fit into a limited space, such as inside the flight deck of an aircraft.

[0090] The activation trigger 260 is movably coupled to the handle 108. For example, the activation trigger 260 may be fixed to the underside 262 of the main beam 264 of the handle 108. The activation trigger 260 is configured to be selectively pressed and / or depressed to activate and deactivate the UV lamp 140 of the wand assembly 102 as needed.

[0091] The activation trigger 260 can be positioned anywhere along the length of the handle 108. The activation trigger 260 may have a different shape than that shown. Furthermore, the activation trigger 260 may be smaller or larger than shown. As an example, the activation trigger 260 may be a circular button instead of an elongated bar or beam as shown. Also, optionally, the activation trigger 260 may be located above the main beam 264 or on the extension beam 266 that isolates the handle 108 from the shroud 112. As another example, the activation trigger 260 may be positioned on part of the shroud 112.

[0092] Figure 24 shows a perspective bottom view of the wand assembly 102 of Figure 23. As shown, the reflector 142 is fixed to the underside of the shroud 112.

[0093] Figure 25 shows a perspective bottom view of the wand assembly 102 of Figures 23 and 24 without the UV lamp 140 (for clarity) according to an embodiment of the present disclosure. Figure 26 shows a perspective view of the cooling manifold 270 of the shroud 112 of the wand assembly 102. Referring to Figures 25 and 26, half of the reflector 142 has been removed, exposing the cooling manifold 270 which extends through the shroud 112 and is in fluid communication with the port 120. The cooling manifold 270 has a plurality of air outlets 271 which allow air supplied through a hose 122 (for example, shown in Figure 23) coupled to the port 120 to pass through the UV lamp 140 when in operation. In this way, the UV lamp 140 is cooled during operation. The supplied air passes over and around the reflector 142 (located between the cooling manifold 270 and the UV lamp 140) through channels defined via the reflector 142 and / or between two parts of the reflector 142 (such as the front half of the reflector 142 and the back half of the reflector 142).

[0094] As shown, the cooling manifold 270 is formed within the shroud 112. In at least one embodiment, the disinfection head 106, including the shroud 112, is part of a wand assembly 102 of a portable disinfection system. In at least one other embodiment, the disinfection head 106, including the shroud 112, may be part of a permanent, fixed disinfection system. For example, the disinfection head 106, including the shroud 112, may be part of a fixed and / or permanent disinfection system in a restroom or galley within the interior cabin of a vehicle, and / or in, for example, a confined space of a vehicle or a fixed building.

[0095] In at least one embodiment, the disinfection system, such as the portable disinfection system 100, includes a wand assembly 102. The wand assembly 102 includes a UV lamp 140. A cooling manifold 270 is configured to blow air over one or more of the UV lamps 140, such as bulbs. The wand assembly 102 may also include a two-piece reflector 142, a master power switch, and a trigger switch such as an activation trigger 260 for operating and illuminating the UV lamps 140.

[0096] During use of the wand assembly 102, the case assembly 200 can be positioned away from the area to be disinfected, thereby allowing the operator to transport only the wand assembly 102 to that area, facilitating movement and operation in narrow or confined spaces. The wand assembly 102 may include a 300-watt, 222 nm UV lamp, an optional ranging light, a cooling manifold 270 present along the length of the shroud 112, a reflector 142, a mount (such as a bracket, clamp, and / or fastener) for securing the UV lamp 140 to the shroud 112, a master power switch on the handle 108, and an activation trigger 260 on the handle 108 configured to engage to selectively start and stop the UV lamp 140. The reflector 142 can be made from a Teflon or aluminum sheet, thereby allowing the reflector 142 to provide electromagnetic shielding. The UV lamp 140 can be attached to the shroud 112 with a wire strap or band, which can be placed on top of Teflon tape and dry-woven fiberglass that act as a cushion between the strap and the glass bulb.

[0097] Figure 27 shows a partial perspective bottom view of a disinfection system 300 according to one embodiment of the present disclosure. The disinfection system 300 includes a disinfection head 106. For example, the disinfection head 106 includes a UV lamp 140 fixed within a shroud 112. In at least one embodiment, the disinfection head 106 is part of a wand assembly, such as one of the wand assemblies described herein, and the disinfection system 300 is a portable disinfection system, such as one of the portable disinfection systems described herein. The wand assembly can be coupled to a backpack assembly, a case assembly, and / or a cart, etc. In at least one other embodiment, the disinfection head 106 is a fixture in a confined space. For example, the disinfection head 106 can be fixed in a sealed space such as a washroom and / or galley.

[0098] The UV lamp 140 includes one or more UV emitters. The UV lamp 140 may be a single, integrated structure. Optionally, the UV lamp 140 may include multiple UV modules.

[0099] The disinfection system 300 includes a cooling manifold 270 as described with respect to Figures 25 and 26. The cooling manifold 270 is configured to supply air 302 around the UV lamp 140. When the UV lamp 140 emits UV light, the air 302 cools the UV lamp 140. Furthermore, the cooling manifold 270 is also configured to direct the air 302 through the cooling manifold 270 so that the air 302 and the generated ozone are discharged, for example, by exhaust.

[0100] The cooling manifold 270 can be formed integrally with the shroud 112. In at least one other embodiment, the cooling manifold 270 is coupled to the shroud 112. The cooling manifold 270 can be located in restrooms, galleys, on the flight deck, or in various areas within a vehicle, or in a fixed building.

[0101] Figure 28 shows a perspective bottom view of a shroud 112 according to one embodiment of the present disclosure. As shown, the cooling manifold 270 is formed within the shroud 112. A UV lamp 140 (not shown in Figure 28) is fixed below (or above) the cooling manifold 270.

[0102] In at least one embodiment, the cooling manifold 270 includes a plurality of air outlets 271. The air outlets 271 can be linearly aligned. For example, the cooling manifold 270 includes a linear array of rectangular air outlets 271, such as slots. Alternatively, instead of a plurality of air outlets 271, a single long air outlet 271 can be used.

[0103] Port 120 includes a channel 304 that is in fluid communication with the cooling manifold 270. As previously mentioned, port 120 is configured to connect to a hose 122 (for example, as shown in Figure 2). The hose 122 can be connected to a backpack assembly, cart, case assembly, etc., which may include a fan, blower, etc. In at least one other embodiment, the hose 122 can be connected to a fixed fan or blower, such as in a confined space.

[0104] Air is supplied to the cooling manifold 270 via port 120. The air passes radially around the UV lamp 140. Port 120 may also allow air and ozone to be discharged through it. The shroud 112 may also include an exhaust port that allows the generated ozone to pass through it.

[0105] Figure 29 shows a perspective cross-sectional view of the cooling manifold 270 within the shroud 112 of Figure 28. Figure 30 shows a perspective cross-sectional view of the oriented slot of the cooling manifold 270 according to one embodiment of the present disclosure. Figure 31 shows a side internal view of the shroud of Figure 28. Referring to Figures 28 to 31, the cooling manifold 270 includes a plenum 306 defined by a wall 308. The wall 308 may be part of the shroud 112. As shown, the cooling manifold 270 is positioned above (or below, depending on orientation) the air supply line 312, and the air supply line 312 is positioned above (or below, depending on orientation) the air outlet 271.

[0106] The plenum 306 is in fluid communication with the channel 304 of port 120 via a connecting conduit 310, which is defined by a wall 308. The plenum 306 is located adjacent to the air supply line 312. The air supply line 312 fluidly connects the plenum 306 to the air outlet 271.

[0107] The air supply line 312 includes a directional slot 320. The directional slot 320 is defined by an arc-shaped fin 322. The arc-shaped fin 322 may be semicircular in shape. The directional slot 320 is defined between two adjacent fins 322. Each directional slot 320 is fluidically coupled to its respective air outlet 271. The cooling manifold 270 may include more or fewer air outlets 271 and directional slots 320 than shown. Optionally, the air supply line 312 may not include the directional slots 320. Instead, the plenum 306 can be fluidly coupled to the air outlets 271 without the directional slots 320.

[0108] During operation, cooling air 330 is supplied to the cooling manifold 270 via channel 304 of port 120. The air 330 passes through channel 304, enters the connecting conduit 310, and enters the plenum 306. The air 330 is forced and / or directed in other ways, for example, via a fan or blower. The air 330 in the plenum 306 then passes through the air supply line 312 and exits through the air outlet 271 around the UV lamp 140 to cool the UV lamp 140.

[0109] The arc-shaped fins 322 provide curved, arc-shaped directional slots 320 that direct the compressed air 330 around the UV lamp 140. For example, the curved shape of the fins 322 provides an arc-shaped airflow around the UV lamp 140, thereby providing effective and uniform cooling around the UV lamp 140.

[0110] The directional slots 320 are sized, molded, and configured to push air radially around the UV lamp 140. The directional slots 320 help create a jet of airflow. The directional slots 320 provide vanes that can be rotated at an angle (for example, the fins 322 can be angled) so that air flows around the UV lamp 140 in a desired path, providing uniform cooling along the length of the bulb (as opposed to simply pushing fan air along the sides or edges of the UV lamp 140).

[0111] The forced air 330 cools the UV lamp 140 and passes through one or more openings 332 formed through the shroud 112. In this way, the forced air 330 pushes out the ozone generated within the shroud 112 through the openings 332, thereby ensuring that the ozone concentration is reduced. Thus, the cooling manifold 270 ensures that the ozone generated by the operation of the UV lamp 140 is safely dispersed.

[0112] The cooling manifold 270 ensures that the air 330 is distributed more uniformly along the length of the UV lamp 140. Thus, the cooling manifold 270 ensures effective and efficient cooling of the UV lamp 140.

[0113] Referring again to Figure 28, an exhaust port 340 can be formed within the shroud 112. The exhaust port 340 can be located at the opposite end of the shroud 112 from port 120. Additional exhaust ports 340 can be formed within the shroud 112. Exhaust ports 340 can be formed in various other areas of the shroud 112. The exhaust ports 340 are configured to allow air and ozone to be discharged from the shroud 112.

[0114] In at least one embodiment, the exhaust manifold 342 is formed around the periphery of the shroud 112. The exhaust manifold 342 includes a plurality of exhaust ports 340 that are in fluid communication with the interior of the shroud 112, for example, through one or more ducts. The exhaust manifold 342 may run along both sides of the shroud 112. The exhaust manifold 342 allows air and ozone generated within the shroud 112 to be uniformly discharged from the shroud 112.

[0115] Each exhaust port 340 may include a hood 346 having an open end 348. An opening 350 is formed via the open end 348. The opening 350 is in fluid communication with an exhaust duct, passage, etc., which is in fluid communication with the internal chamber of the shroud 112. For example, each opening 350 is in fluid communication with an opening 352 which is in fluid communication with the internal chamber 113 of the shroud 112. Optionally, the shroud 112 may not include the exhaust manifold 342 and / or the individual exhaust ports 340.

[0116] The shroud 112 may further include a cover plate, such as the cover plate 154 described with respect to Figure 14. In at least one other embodiment, the shroud 112 does not include a cover plate.

[0117] Figure 32 shows a schematic block diagram of a disinfection system 300 coupled with a fan 400 and an ozone scrubber 402 according to one embodiment of the present disclosure. In at least one embodiment, the disinfection system 300 differs from the fan 400 and the ozone scrubber 402. In at least one other embodiment, the disinfection system 300 includes one or both of the fan 400 and / or the ozone scrubber 402 in a backpack assembly, case assembly, cart, etc.

[0118] The fan 400 is in fluid communication with the cooling manifold 270 (such as any of those described herein) via one or more conduits 404, such as one or more hoses, one or more tubes, and / or one or more ducts. The fan 400 generates an airflow that produces air to be pushed into the cooling manifold 270 to cool the UV lamp 140, as described herein. The disinfection system 300 may also include an exhaust subsystem 406, such as one or more exhaust ports or one exhaust manifold, as described herein.

[0119] Air cools the UV lamp 140 and is discharged through the exhaust subsystem 406 along with the generated ozone. The exhaust subsystem 406 can then be fluidly connected to the ozone scrubber 402, for example, through one or more conduits 408. The ozone scrubber 402 neutralizes, deactivates, and / or converts the ozone into air, for example. The scrubbed air can then be recirculated in a sealed spacer, for example, through an environmental control system, an air conditioning system, etc. Optionally, the disinfection system 300 does not have to be connected to the ozone scrubber 402.

[0120] In at least one embodiment, the disinfection system 300 can be used to disinfect components within a confined space, such as the flight deck of an aircraft. For example, the disinfection system 300 may include a wand assembly, as described herein. The disinfection system 300 can be used to reduce or otherwise replace ozone concentration levels during use. For example, the backpack or case assembly of the disinfection system 300 may be placed outside a confined space (such as a flight deck) that allows a fan 400 to draw in air. While the wand assembly is in use in the confined space (the door to the confined space may be slightly supported and open due to the hose passing through), the wand assembly exhausts ozone via an exhaust subsystem 406, while simultaneously supplying cool air to a UV lamp 140 via a cooling manifold 270. The exhaust subsystem 406 can push the exhausted air into the confined space, where it is then naturally drawn out through the open door. Thus, the ozone is moved and dispersed from the enclosed space.

[0121] Referring to Figures 1 to 32, certain embodiments of the present disclosure provide a disinfection system including a disinfection head 106. The disinfection head 106 includes a UV lamp 140. A cooling manifold 270 is configured to supply air to the UV lamp 140 to cool it. In at least one embodiment, the disinfection head 106 also includes an exhaust subsystem 406 configured to discharge ozone from the disinfection head 106.
