Fig. 1 shows a perspective view of a portable disinfecting system 100 worn by an individual 101 according to one embodiment of the present disclosure. The portable sanitizing system 100 includes a wand assembly 102 coupled to a backpack assembly 104 that is removably secured to an individual by a harness 105. Cane assembly 102 includes a disinfectant head 106 coupled to a handle 108. In at least one embodiment, the disinfection head 106 is movably coupled to the handle 108 by a coupler 110.
In at least one other embodiment, portable disinfecting system 100 may not be worn by individual 101. For example, portable sterilization system 100 may include a case assembly configured to be opened and closed. The case assembly may store cane assembly 102 when not in use. The case assembly may be opened to allow cane assembly 102 to be removed and manipulated. In at least one other embodiment, portable sterilization system 100 may include a movable cart assembly.
As shown in fig. 1, cane assembly 102 is in a stowed position. In this stowed position, the cane assembly 102 is removably secured to a portion of the backpack assembly 104, such as by one or more rails, clips, latches, straps, tethers, etc.
In at least one other embodiment, cane assembly 102 is stowed within the case assembly in a stowed position. For example, cane assembly 102 in the stowed position is housed within a closed case assembly. The case assembly may be opened to allow removal and deployment of cane assembly 102.
Fig. 2 shows a perspective side top view of cane assembly 102 in accordance with one embodiment of the present disclosure. The disinfection head 106 is coupled to a handle 108 by a coupler 110. The disinfection head 106 comprises a shield 112, the shield 112 having an outer cap 114 extending from a proximal end 116 to a distal end 118. The shroud 112 houses the UV lamp as described herein.
Optionally, cane assembly 102 may include a disinfectant head 106 connected to a stationary handle. Optionally, cane assembly 102 may include a disinfectant head 106 connected to a stationary handle. Further, the cane assembly 102 may be sized and shaped differently than illustrated.
A port 120 extends from proximal end 116. The port 120 is coupled to a hose 122, which hose 122 is in turn coupled to the backpack assembly 104 (shown in figure 1). The hose 122 houses electrical wires, cables, wiring, or the like that couple a power source or power supply (e.g., one or more batteries) in the backpack assembly 104 (shown in figure 1) to the UV lamp 140 within the shroud 112. Alternatively, wires, cables, wiring or the like may be external to the hose 122. In at least one embodiment, the hose 122 also houses an air delivery line (e.g., an air tube) that fluidly couples the interior chamber of the shroud 112 to a blower, vacuum generator, air filter, and/or the like in the backpack assembly 104.
The coupler 110 is secured to the outer cover 114 of the shield 112, e.g., near the proximal end 116. The coupler 110 may include a securing beam 124 secured to the outer cover 114, such as by one or more fasteners, adhesives, and/or the like. An extension beam 126 extends outwardly from the fixed beam 124, thereby spacing the handle 108 from the shroud 112. A bearing assembly 128 extends from the extension beam 126 opposite the fixed beam 124. Bearing assembly 128 includes one or more bearings, rails, and/or the like to allow handle 108 to translate linearly relative to coupler 110 in the direction of arrow a, and/or pivot about a pivot axis in the direction of arc B. Optionally, the fixed beam 124 may include a bearing assembly that allows the disinfection head 106 to translate in the direction of arrow a and/or rotate (e.g., rotate) in the direction of arc B in addition to or in lieu of the handle 108 coupled to the bearing assembly 128 (e.g., the handle 108 may be fixed to the coupler 110).
In at least one other embodiment, cane assembly 102 does not include coupler 110. Instead, for example, the handle 108 may be secured to the shield 112.
In at least one embodiment, the handle 108 includes a rod, post, beam, or the like 130 that may be longer than the shroud 112. Alternatively, the rod 130 may be shorter than the shroud 112. One or more handles 132 are secured to the rod 130. The handle 132 is configured to be grasped or held by an individual. The handle 132 may include ergonomic tactile features 134.
Alternatively, cane assembly 102 may have a different size and shape than illustrated. For example, in at least one example, the handle 108 may be fixed relative to the shroud 112. Further, the handle 108 may not be configured to move relative to itself and/or the shield 112. For example, the handle 108 and the shield 112 may be integrally molded and formed as a single unit.
Fig. 3 shows a perspective rear view of the cane assembly 102 of fig. 2. Fig. 4 shows a perspective side view of the cane assembly 102 of fig. 2. Referring to fig. 3 and 4, handle 108 may be pivotably coupled to coupler 110 by a bearing 136 having a pivot shaft 138, which pivot shaft 138 pivotably couples handle 108 to coupler 110. Handle 108 may be further configured to linearly translate in and out of bearing 136. For example, the handle 108 may be configured to retract and extend. Alternatively or additionally, in at least one embodiment, the handle 108 may include a telescoping 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.
Fig. 5 shows a perspective view of the portable sterilization system 100 in a compact deployment position, according to one embodiment of the present disclosure. As shown in fig. 5, the cane assembly 102 is removed from the backpack assembly 104 (shown in fig. 1) to a compact deployment position. Hose 122 connects cane assembly 102 to backpack assembly 104. In the compact deployed position, disinfection head 106 is fully retracted relative to handle 108.
Fig. 6 shows a perspective view of portable disinfecting system 100 with disinfecting head 106 in an extended position according to one embodiment of the present disclosure. To extend disinfection head 106 relative to handle 108, disinfection head 106 is slid outward relative to handle 108 in the direction of arrow a' (or handle 108 is slid rearward relative to disinfection head 106). As described above, the disinfection head 106 is linearly translatable relative to the handle 108 in the direction of arrow a' via the coupler 110. As shown in fig. 6, the outward extension of the disinfection head 106 allows the portable disinfection system 100 to easily reach remote areas. Alternatively, disinfection head 106 may not translate linearly relative to handle 108.
Fig. 7 shows a perspective view of portable disinfecting system 100 with disinfecting head 106 in an extended position and handle 108 in an extended position according to one embodiment of the present disclosure. To reach further distally, the handle 108 may be configured to translate linearly, e.g., via a telescoping portion, to allow the disinfection head 106 to reach further distally outward. Alternatively, the handle 108 may not be configured to extend and retract.
In at least one embodiment, the handle 108 may include a locking member (lock) 109. The lock 109 is configured to be selectively operated to secure the handle 108 in a desired extended (or retracted) position.
Fig. 8 shows a perspective view of portable disinfecting system 100 with disinfecting head 106 rotated relative to handle 108 according to one embodiment of the present disclosure. As described above, the disinfection head 106 is configured to rotate relative to the handle 108 via the coupler 110. Rotating the disinfection head 106 relative to the handle 108 will allow the disinfection head 106 to move to a desired position and sweep or reach areas that would be difficult to reach if the disinfection head 106 were rigidly fixed to the handle 108. Alternatively, the disinfection head 106 may not be rotatable relative to the handle 108.
Fig. 9 shows a perspective end view of the UV lamp 140 and reflector 142 of the disinfection head 106 according to one embodiment of the present disclosure. The UV lamp 140 and the reflector 142 are secured within the shroud 112 of the disinfection head 106 (e.g., as shown in fig. 2). In at least one embodiment, the reflector 142 is secured to the bottom side 141 of the shroud 112, such as by one or more adhesives. As another example, the reflector 142 is an integral part of the shroud 112. For example, the reflector 142 may be or otherwise provide the bottom side 141 of the shroud 112. The reflector 142 provides a reflective surface 143 (e.g., formed of Teflon (Teflon), a specular surface, and/or the like), the reflective surface 143 configured to reflect UV light emitted by the UV lamp 140 outward. In at least one example, shroud 112 can be or include a housing formed from fiberglass, and reflector 142 can be formed from Teflon (Teflon) that provides 98% reflectivity. In at least one embodiment, the reflector 142 may be a multi-piece (multi-piece) reflector.
The reflector 142 may extend along the entire length of the bottom side 141 of the shroud 112. Alternatively, the reflector 142 may extend along less than the entire length of the bottom side 141 of the shroud 112.
The UV lamp 140 may extend along the entire length (or substantially along the entire length, e.g., between the ends 116 and 118). The UV lamp 140 is secured to the reflector 142 and/or the shroud 112 by, for example, one or more mounts (e.g., brackets). The UV lamp 140 includes one or more UV light emitters, such as one or more light bulbs, light emitting elements (e.g., light emitting diodes), and/or the like. In at least one embodiment, the UV lamp 140 is configured to emit UV light in the far UV spectrum (e.g., wavelengths between 200nm 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 300W 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 portions of the UV spectrum (e.g., 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 UV spectrum or the UVC spectrum.
As shown, the reflector 142 includes flat upstanding side walls 144 that are joined together by an upper curved wall 146. The upper curved wall 146 may curve outwardly away from the UV lamp 140. For example, the upper curved wall 146 may have a parabolic cross-section and/or profile.
It has been found that straight linear sidewalls 144 provide the desired reflection and/or concentration of UV light emitted from UV lamp 140 toward and onto the desired location. Alternatively, the sidewalls 144 may not be linear and planar.
Fig. 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 fig. 10 is similar to the reflector 142 shown in fig. 9, except that the side walls 144 may be angled outwardly from the upper curved wall 146.
Fig. 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 walls 144 may be curved according to the curvature of the upper curved wall 146.
Fig. 12 shows a perspective top view of the disinfection head 106. Fig. 13 shows a perspective bottom view of the disinfection head 106. Fig. 14 shows an axial cross-sectional view of the disinfection head 106 taken through line 14-14 of fig. 12. Referring to fig. 12-14, air 150 is configured to be drawn into the disinfection head 106 through one or more openings 152 (or simply open chambers) of the shroud 112. Air 150 is drawn into the disinfection head 106, for example, via a vacuum generator within the backpack assembly 104 (shown in figure 1). 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 proceeds into the port 120 and into the hose 122, such as an air tube within the hose 122. The air 150 not only cools the UV lamps 140, but also removes ozone within the shroud 112 that may be generated by operation of the UV lamps 140. The air 150 may be drawn into an air filter (e.g., a carbon filter) within the backpack assembly 104.
In at least one embodiment, portable sanitizing system 100 can also include an alternative ozone mitigation system. As one example, the ozone abatement system may be disposed in the shroud 112 or another portion of the system, and may include an inert gas bath (inert gas bath) or a surface inert gas system, such as described in U.S. patent No. 10,232,954.
Referring to FIG. 13, in particular, the damper 153 may be secured to an exposed lower peripheral edge 155 of the shroud 112. The shock absorber 153 may be formed of a resilient material such as rubber, another resilient material, open or closed cell foam, and/or the like. In the event that the disinfection head 106 accidentally contacts a surface, the bumper 153 protects the disinfection head 106 from damage. The shock absorber 153 also protects the surface from damage.
The openings 152 may be spaced around the lower surface of the shroud 112 so that they do not provide a direct view of the UV lamp 140. For example, the opening 152 may be positioned below a portion spaced apart from the UV lamp 140.
Referring to fig. 14, in particular, the disinfection head 106 may include a cover plate 154 under the UV lamp 140. The cover plate 154 may be formed of, for example, glass, and may be configured to filter UV light emitted by the UV lamp 140. The UV lamp 140 may be secured in an interior chamber 156 defined between the reflector 142 and the cover plate 154. In at least one embodiment, the cover plate 154 is or includes a far UV band pass filter. For example, the cover plate 154 may be a 222nm band pass filter that filters the UV light emitted by the UV lamp 140 to a wavelength of 222 nm. In this way, the UV light emitted from the disinfection head 106 may be emitted at a wavelength of 222 nm. As another example, the cover plate 154 may be a 254nm band pass filter that filters the UV light emitted by the UV lamp 140 to a 254nm wavelength.
Referring to fig. 13 and 14, a rim 157 (e.g., a 0.020 inch thick titanium rim) may connect the cover plate 154 to the shroud 112. The rim 157 may distribute impact loads therethrough and/or therearound.
In at least one embodiment, a ranging Light Emitting Diode (LED)159 may be disposed near the end of the UV lamp 140. The ranging LED 159 may be used to determine a desired distance to, for example, a structure to be disinfected. In at least one embodiment, the ranging LED 159 may be disposed on or in the rim 157 and/or the cover plate 154. As another example, the disinfection head 106 may be configured for range guidance (range guidance), as disclosed in U.S. provisional application No. 63/027,869, filed on 20/5/2020.
Fig. 15 shows a perspective end view of the UV lamp 140 secured to a mounting bracket or clip 160 according to one embodiment of the present disclosure. Each end of the UV lamp 140 may be coupled to a mounting bracket or clamp 160, which mounting bracket or clamp 160 secures the UV lamp 140 to the shroud 112 (as shown in fig. 12-14). A buffer (e.g., a thin (e.g., 0.040 inch) silicon sheet) may be disposed between the end of the UV lamp 140 and the holder 160. Alternatively, the UV lamp 140 may be secured to the shroud 112 by a bracket or fixture of a different size and shape than illustrated. As another example, the UV lamp 140 may be secured to the shroud 112 by adhesives, fasteners, and/or the like.
Figure 16 shows a perspective exploded 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 interior chamber 178 is defined between the front wall 170, the rear shell 172, the base 174, and the cap 176. One or more batteries 180 (e.g., rechargeable lithium batteries) are housed in the internal chamber 178. An air generating subsystem 182 is also housed in the internal chamber 178. The air generation subsystem 182 is in fluid communication with an air tube within the hose 122 (e.g., as shown in fig. 2). The air generating subsystem 182 may include an air flow device, such as a vacuum generator, blower, or the like. The air flow device is configured to generate an air flow to cool the UV lamp, draw air from the disinfection head 106 into the backpack assembly 104 and out through the exhaust vents, draw or otherwise remove the generated ozone, etc. from the shroud 112.
One or more air filters 183 (e.g., carbon filters) are within the backpack assembly 104. The air filter 183 is in communication with an air tube or other such delivery conduit or line that conveys air through the hose 122 and into the backpack assembly 104. The air filter 183 is configured to filter air drawn from the hood 112 into the backpack assembly 104. For example, air filter 183 may be configured to remove, deactivate, or otherwise neutralize ozone.
A battery 180 and/or power source within the backpack assembly 104 provides operating power for the UV lamp 140 (e.g., as shown in fig. 2) of the disinfection head 106. The top wall 176 may be removably coupled to the front wall 170 and the rear shell 172. For example, the top wall 176 may be removed to provide access to the battery 180 (e.g., to remove and/or recharge the battery). Additional space may be provided within the backpack assembly 104 for the storage of supplies (supplies), additional batteries, additional components, etc. In at least one embodiment, the front wall 170, rear shell 172, base 174, and top cap 176 may be formed from fiberglass epoxy.
Figure 17 shows a perspective front view of a back strap 105 coupled to a backpack assembly 104 according to one embodiment of the present disclosure. The back straps 105 may include shoulder straps 190 and/or straps or ties 192 for the wrist or hip to allow an individual to comfortably wear the backpack assembly 104.
Referring to fig. 1-17, in operation, an individual may walk through an area wearing the backpack assembly 104. When a structure to be disinfected is found, an individual may position the grip handle 108 and position the disinfection head 106 as desired, for example by extending and/or rotating the disinfection head 106 relative to the handle 108, and then the individual may engage, for example, an activation button on the handle 108 to activate the UV lamp 140 to emit disinfecting UV light onto the structure. As the UV lamp 140 is activated, air 150 is drawn into the shroud 112 to cool the UV lamp 140 and transfer any ozone generated into the backpack assembly 104 where it is filtered by the air filter 183.
The extendable pole assembly 102 allows the disinfectant head 106 to reach remote areas, such as across a full set of three passenger seats from one row in the interior cabin of a commercial aircraft.
Fig. 18 shows an ultraviolet light spectrum. Referring to fig. 1-18, in at least one embodiment, the disinfection head 106 is configured to emit disinfecting UV light (by operation of the UV lamp 140) within the far UV spectrum (e.g., between 200nm and 230 nm). 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 within the UVC spectrum (e.g., between 230nm to 280 nm). For example, the disinfection head 106 emits disinfection UV light having a wavelength of 254 nm. In at least one other embodiment, the disinfection head 106 is configured to emit disinfection UV light in a different portion of the UV spectrum.
Fig. 19 shows a perspective view of a portable sterilization system 100 according to one embodiment of the present disclosure. The portable disinfecting system 100 includes a case assembly 200, the case assembly 200 being configured to store the cane assembly 102 (hidden from view in fig. 19) when the case assembly 200 is in a closed position as shown in fig. 19.
For example, the case assembly 200 may be formed of plastic. The case assembly 200 includes a main body 201, e.g., a housing, a lower body portion, etc. A cover 202 (e.g., a lid or upper body portion) is movably coupled to the body 201. For example, the cover 202 may be coupled to the body 201 by a hinge that allows the cover 202 to be opened and closed relative to the body 201.
The body 201 includes a base 204 connected to a rear wall 206, side walls 208 and a top wall 210. The cover 202 is movably coupled to the first sidewall 208, such as by a hinge. One or more latches 212 are disposed on the second sidewall 208 opposite the first sidewall 208. The latch 212 is configured to engage one or more reciprocal latch members 213 extending from the cover 202 to secure the cover 202 in the closed position. Latch 212 may be engaged by an individual to disengage latch member 213 to allow cover 202 to pivot into the open position.
A handle 214 is secured to the housing assembly 200. For example, the handle 214 is pivotally secured to the side wall 208. Handle 214 is configured to be grasped by an individual to enable portable disinfecting system 100 to be carried. Alternatively, the handle 214 may be secured to other portions of the case assembly 200, such as the top wall 210. In at least one embodiment, the handle 214 can be configured to retract into the case assembly 200 to a fully retracted position and extend (telescope out) of the case assembly 200 to a fully extended position.
Casters 216 or other similar wheels may be rotatably secured to a portion of the case assembly 200. For example, two casters 216 may be rotatably secured to the base 204 proximate the rear wall 206. The individual may tilt the case assembly 200 so that the casters 216 contact the floor. In this manner, an individual may roll portable disinfecting system 100 by casters 216 (and optionally by the handle in an extended position from top wall 210). Alternatively, the case assembly 200 may not include casters 216.
The hose 122 may extend outwardly from the tank assembly 200. In the closed position, the hose 122 can be coiled over the cover 202 when the pole assembly 102 is in the stowed position within the case assembly 200. Hose retainer 218 may secure hose 122 in place on cover 202. For example, the hose retainer 218 can include a flexible fabric sheet 220 secured to a first side 221 of the cover 202 and can be removably secured to an opposing second side 222 of the cover 202, such as by one or more fastening members 224 (e.g., hooks and loops, latches, clips, and/or the like). Hose retainer 218 is configured to secure hose 122 to cover 202 when cane assembly 102 is in the storage chamber of case assembly 200 and cover 202 is in the closed position. Alternatively, the hose 122 can be housed within the storage compartment of the case assembly 200 when the cane assembly 102 is not in use. That is, when pole assembly 102 is also in the storage chamber and cover 202 is in the closed position, the storage chamber may be sized and shaped to also accommodate hose 122.
The cane assembly 102 within the case assembly 200 in the closed position is protected from inadvertent engagement, bumping, etc. That is, by storing the pole assembly 102 within the closed case assembly 200, the portable sterilization system 100 protects the pole assembly 102 from potential injury and increases the useful life of the pole assembly 102 when the pole assembly 102 is not in use.
Fig. 20 shows a perspective view of portable sterilization system 100 with case assembly 200 in an open position according to one embodiment of the present disclosure. As shown, the cover 202 is opened by a hinge 226, which hinge 226 pivotably couples the cover 202 to the body 201.
An interior or storage chamber 228 is defined between the base 204, the side walls 208, the rear wall 206, and the top wall 210 (and the cover 202 when closed). The various components of portable sterilization system 100 may be stored within storage compartment 228. For example, as described with respect to fig. 16, the components within the backpack assembly 104 may be housed within a stowage compartment 228.
For example, pole assembly 102 is received within storage compartment 228 when not in use. Additionally, one or more batteries (e.g., a secondary lithium battery) may be housed within the storage compartment 228.
An air generating subsystem (e.g., a cooling fan) may also be housed within the stowage compartment 228. The air generation subsystem may be in fluid communication with an air tube within hose 122. The hose 122 may be removably connected to the air generating subsystem. In at least one embodiment, hose 122 is configured to couple and decouple with cane assembly 102 and the air generating subsystem. That is, hose 122 may be removably coupled to cane assembly 102 and the air generating subsystem.
One or more air filters (e.g., carbon filters) may also be within the holding chamber 228. The air filter may be in fluid communication with an air tube or other such delivery tube or line that directs air through the hose 122.
Fig. 21 shows a perspective view of portable sterilization system 100 with case assembly 200 in an open position according to one embodiment of the present disclosure. Cane assembly 102 is configured to be stowed in a stowage compartment 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 into the wand assembly 102 in order to cool the UV lamp 140 during activation.
The second end 232 of the hose 122 may be connected to a port 234, the port 234 extending into and through a portion of the main body 201, such as through a portion of the top wall 210. A port 234 connects the hose 122 to an air generating subsystem, such as a cooling fan 236 within the stowage compartment 228. The cooling fan 236 can be activated to generate cooling air that is delivered to the wand assembly 102 via the hose 122 (e.g., an air tube within the hose 122, or via an internal passage of the hose 122 itself).
One or more batteries 180 may also be stowed within the storage compartment 228. For example, three batteries 180 may be within the storage compartment 228.
A power supply 238 is also housed within the storage compartment 228. Power source 238 may be coupled to cane assembly 102 by a power cord (e.g., via a plug and socket adapter) to provide power to cane assembly 102. Further, the power source 238 may be configured to provide power to the battery 180 (e.g., to recharge the battery 180). Battery 180 may be secured to cane assembly 102 and provide power to cane assembly 102 so that cane assembly 102 may be used without connection to power source 238.
Cooling fan 236 is coupled to hose 122 via port 234. The cooling fan 236 may also include a turn-around port coupled to an interior portion of the power supply 238. In this manner, cooling air may be delivered to both hose 122 (and thus to cane assembly 102) and power supply 238, thereby providing cooling to both cane assembly 102 and power supply 238.
A hole 240 may be formed through a portion of the case assembly 200. For example, the hole 240 may be formed through a portion of the top wall 210 and sized and shaped to allow the hose 122 to pass therethrough. In this manner, hose 122 can still be connected to pole assembly 102 even when pole assembly 102 is received within storage compartment 228 and cover 202 is closed. As shown and described with respect to fig. 19, the other portion of hose 122 between first end 230 and second end 232 may be secured to cover 202 by hose retainer 218.
As shown, a handle 214 may be secured to the top wall 210 of the body 201. The handle 214 may be configured to retract into the body 201 and extend out of the body 201. For example, the handle 214 may be a telescoping (televiewing) handle.
Cane assembly 102 may be removably secured within a storage compartment 228. For example, the pole assembly 102 can be removably secured within the storage compartment 228 by one or more latches, clips, or via an interference fit with a conformal portion of the case assembly 200.
The power source 238 may be fixed in place within the storage compartment 228. For example, the power source 238 may be secured in the storage compartment 228 by one or more fasteners, adhesives, or the like. Alternatively, the power source 238 may be secured in place by one or more latches, clips, or the like.
The battery 180 may similarly be in a fixed position within the storage compartment 228. For example, the battery 180 may be secured in the storage compartment 228 by one or more fasteners, adhesives, or the like. Alternatively, the battery 180 may be secured in place by one or more latches, clips, or the like. In at least one other embodiment, the battery 180 may be removable and configured to be directly coupled to the hand wand assembly 102 to provide power thereto.
Fig. 22 shows a perspective view of portable sterilization system 100 with case assembly 200 in an open position according to one embodiment of the present disclosure. The power cord 250 may also be stowed within the stowage compartment 228. When the cover 202 is closed, the power cord 250 is contained within the case assembly 200 and the portable disinfecting system 100 is moved when the pole assembly 102 is not being operated.
Optionally, a power cord 250 connects the power supply 238 to a source of electrical power (e.g., a wall outlet). In addition to supplying air to wand assembly 102, hose 122 routes electrical cables and the like from power source 238 and battery 180 to wand assembly 102.
Alternatively, hose 122 may not include an electrical connection to cane pack 102. Conversely, with cane assembly 102, power cord 250 may be inserted into cane assembly 102 via plug 252 to supply power from power source 238 and/or battery 180. In this embodiment, plug 252 of power cord 250 is connected to an interactive socket of wand assembly 102 when wand assembly 102 is operated. The opposite end of the power cord 250 is connected to the power source 238 (and/or the battery 180). Power cord 250 extends out of case assembly 200 through hole 240. Accordingly, cane assembly 102 may be removed from storage chamber 228 and connected to hose 122 and power cord 250 that extends through hole 240. The cover 202 may then be closed, thereby securely holding the power source 238, battery 180, etc. within the storage compartment 228. The pole assembly 102 can then be activated because it is powered via the power source 238 or one or more batteries 180, and the closed case assembly 200 can be moved, such as by an individual grasping the handle 214 and rolling the case assembly 200 via the casters 216 (as shown in fig. 19 and 20).
In addition, the holes 240 allow intake air to be drawn into the storage chamber 228 even when the cover 202 is closed onto the main body 201. Therefore, even when the cover 202 is closed, the cooling fan 236 can receive fresh air.
The power supply 238 may be configured to receive power from a standard power source (e.g., an ac power source). For example, the power supply 238 may be connected to an alternating current power source via a power cord. A power cord 250 is connected to wand assembly 102 and is configured to deliver power to wand assembly 102 to operate UV lamp 140 with power received from power source 238 and optional battery 180. For example, when power source 238 is connected to an AC power source, cane assembly 102 is powered by power source 238. In the absence of such power, cane assembly 102 may be powered by battery 180. For example, cane assembly 102 receives power from battery 180 when power source 238 is not plugged into an electrical outlet. If the power source 238 is plugged into an electrical outlet, one or more relays in the power source 238 switch from the battery 180 to AC power from the electrical outlet.
Fig. 23 shows a perspective side view of the cane assembly 102 in accordance with one embodiment of the present disclosure. As shown, the handle 108 may be fixed relative to the shield 112. For example, the handle 108 may be integrally molded and formed with the shield 112. Cane assembly 102 may be small and compact to fit in confined spaces, such as in the cockpit of an aircraft.
The activation trigger 260 is movably coupled to the handle 108. For example, the activation trigger 260 may be secured to a bottom side 262 of a main beam 264 of the handle 108. Activation trigger 260 is configured to be selectively pressed and/or de-pressed to activate and deactivate UV light 140 of cane assembly 102 as desired.
The activation trigger 260 may be positioned anywhere along the length of the handle 108. The activation trigger 260 may have a shape different than that illustrated. Further, the activation trigger 260 may be smaller or larger than illustrated. As one example, the activation trigger 260 may be a circular button rather than the illustrated elongated rod or beam. Also, optionally, the activation trigger 260 is located on a top portion of the main beam 264 or on an extension beam 266 that spaces the handle 108 from the shroud 112. As another example, the activation trigger 260 may be located on a portion of the shroud 112.
Fig. 24 shows a perspective bottom view of the cane assembly 102 of fig. 23. As shown, the reflector 142 is secured to the underside of the shroud 112.
Fig. 25 shows a perspective bottom view of the cane assembly 102 of fig. 23 and 24 without the UV lamp 140 (for clarity) according to one embodiment of the present disclosure. Fig. 26 shows a perspective view of the cooling manifold 270 of the shroud 112 of the cane assembly 102. Referring to fig. 25 and 26, half of the reflector 142 is removed to expose a cooling manifold 270 extending through the shroud 112 and in fluid communication with the port 120. The cooling manifold 270 has a plurality of air outlets 271 that allow delivery of air through hoses 122 (such as shown in fig. 23) coupled to the ports 120 to pass over the UV lamps 140 when the UV lamps 140 are activated. In this way, the UV lamp 140 is cooled during operation. The delivered air passes over and around reflector 142 (which is disposed between cooling manifold 270 and UV lamp 140) via a passage defined through reflector 142 and/or between two portions of reflector 142 (e.g., a first half of reflector 142 and a second half of reflector 142).
As shown, the cooling manifold 270 is formed in the shroud 112. In at least one embodiment, the disinfection head 106 including the shield 112 is part of the cane assembly 102 of a portable disinfection system in at least one other embodiment, the disinfection head 106 including the shield 112 can be part of a permanently fixed disinfection system. For example, the disinfection head 106 including the shield 112 may be part of a stationary and/or permanent disinfection system, for example, within a washroom, kitchen, etc. within an interior compartment of a vehicle and/or within an enclosed space of a vehicle or stationary building.
In at least one embodiment, a disinfecting system (e.g., portable disinfecting system 100) includes a hand wand assembly 102. Cane assembly 102 includes a UV lamp 140. The cooling manifold 270 is configured to allow air to be blown through the UV lamp 140, such as one or more bulbs of the UV lamp 140. The cane assembly 102 may also include a two-piece reflector 142, a master power switch and a trigger switch (e.g., activation trigger 260) to activate and illuminate the UV lamp 140.
During use of the pole assembly 102, the case assembly 200 can be positioned away from the area to be sanitized, thereby allowing the operator to transport only the pole assembly 102 to the area and facilitating movement and operation in confined or restricted spaces. The cane assembly 102 may include a 300 watt 222nm UV lamp, optional ranging lamps, a cooling manifold 270 arranged along the length of the shroud 112, a reflector 142, a base (e.g., brackets, clamps, fasteners, etc.) 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 activate and deactivate the UV lamp 140. The reflector 142 may be made of Teflon or aluminum sheet material, which allows the reflector 142 to provide electromagnetic shielding. The UV lamp 140 may be attached to the shroud 112 by a strip or ribbon of wire that may be placed on top of the Teflon tape and dry-woven glass fibers that serve as a gasket between the strip and the glass bulb.
Fig. 27 shows a bottom perspective view of a portion of a sterilization system 300 according to one embodiment of the present disclosure. Disinfection system 300 includes disinfection head 106. For example, the disinfection head 106 includes a UV lamp 140 secured within the shield 112. In at least one embodiment, the disinfection head 106 is part of a hand wand assembly (e.g., any of the hand wand assemblies described herein), and the disinfection system 300 is a portable disinfection system, such as any of the portable disinfection systems described herein. The cane assembly may be coupled to a backpack assembly, case assembly, cart, or the like. In at least one other embodiment, the disinfection head 106 is a stationary device within an enclosed space. For example, the disinfection head 106 may be secured within an enclosed space (e.g., a toilet, a kitchen, etc.).
The UV lamp 140 comprises one or more UV light emitters. The UV lamp 140 may be a unitary structure. Alternatively, the UV lamp 140 may include a plurality of UV modules.
Sterilization system 300 includes cooling manifold 270, such as described with respect to fig. 25 and 26. The cooling manifold 270 is configured to deliver air 302 around the UV lamp 140. When the UV lamp 140 emits UV light, the air 302 cools the UV lamp 140. Furthermore, cooling manifold 270 is also configured to channel air 302 out through cooling manifold 270, such as to vent air 302 and generated ozone through a vent.
The cooling manifold 270 may be integrally formed with the shroud 112. In at least one other embodiment, the cooling manifold 270 is coupled to the shroud 112. The cooling manifold 270 may be disposed in various areas, such as in a washroom, a kitchen, a cockpit or various areas within a vehicle, a fixed building, etc.
Fig. 28 illustrates a perspective bottom view of the shroud 112 according to one embodiment of the present disclosure. As shown, the cooling manifold 270 is formed in the shroud 112. The UV lamp 140 (not shown in fig. 28) is fixed below (or above) the cooling manifold 270.
In at least one embodiment, cooling manifold 270 includes a plurality of air outlets 271. The air outlets 271 may be linearly aligned. For example, the cooling manifold 270 includes a linear array of rectangular air outlets 271 (e.g., slots). As another option, instead of multiple air outlets 271, a single long air outlet 271 may be used.
The port 120 includes a channel 304 in fluid communication with the cooling manifold 270. As described above, the port 120 is configured to couple to a hose 122 (shown, for example, in fig. 2). The hose 122 may be coupled to a backpack assembly, cart, case assembly, etc., containing fans, blowers, etc. In at least one other embodiment, the hose 122 may be coupled to a stationary fan or blower, for example, within the enclosed space.
Air is delivered to the cooling manifold 270 through the port 120. The air flows radially around the UV lamp 140. The port 120 may also allow air and ozone to be expelled therethrough. The shroud 112 may also include a discharge port that allows the generated ozone to pass therethrough.
Fig. 29 shows a perspective cross-sectional view of the cooling manifold 270 within the shroud 112 of fig. 28. FIG. 30 illustrates a perspective cross-sectional view of the vector slot 320 of the cooling manifold 270 according to one embodiment of the present disclosure. Fig. 31 shows an interior side view of the shroud 112 of fig. 28. Referring to fig. 28-31, the cooling manifold 270 includes a plenum 306 defined by walls 308. The wall 308 may be part of the shroud 112. As shown, the cooling manifold 270 is disposed above (or below, depending on the orientation) the air delivery line 312, which in turn is disposed above (or below, depending on the orientation) the air outlet 271.
The plenum 306 is in fluid communication with the passage 304 of the port 120 through a connecting duct 310, for example, defined by a wall 308. The plenum 306 is disposed adjacent to an air delivery line 312. An air delivery line 312 fluidly couples plenum 306 to air outlet 271.
The air delivery line 312 includes a guide slot 320. The guide slot 320 is defined by an arcuate fin 322. The arc-shaped fins 322 may be semi-circular in shape. The guide groove 320 is defined between two adjacent fins 322. Each guide slot 320 is fluidly coupled to a respective air outlet 271. The cooling manifold 270 may include more or fewer air outlets 271 and vector slots 320 than shown. Alternatively, the air delivery line 312 may not include the guide slot 320. In contrast, the plenum 306 may be fluidly coupled to the air outlet 271 without the guide slots 320.
In operation, cooling air 330 is supplied to the cooling manifold 270 through the channels 304 of the port 120. Air 330 passes through the channels 304, enters the connecting tubes 310, and enters the plenum 306. For example, air 330 is pressurized and/or directed via a fan or blower. The air 330 within the plenum 306 then passes through the air delivery lines 312 and out through the air outlets 271 around the UV lamps 140 to cool the UV lamps 140.
The arcuate fins 322 provide curved arcuate guide slots 320 that guide pressurized air 330 around the UV lamp 140. For example, the curved shape of the fins 322 provides an arcuate airflow around the UV lamp 140, thereby providing effective and smooth cooling around the UV lamp 140.
The guide slots 320 are sized and shaped and configured to push air radially around the UV lamp 140. The vector slot 320 helps create an air jet. The guide slots 320 provide blades that can be twisted at an angle (e.g., the fins 322 can be angled) so that the air flows around the UV lamp 140 on a desired path, thereby providing uniform cooling along the length of the bulb (rather than merely pushing the fan air along the sides or ends of the UV lamp 140).
The pressurized air 330 cools the UV lamp 140 and passes through one or more openings 332 formed through the shroud 112. In this manner, the pressurized air 330 forces any ozone generated within the shroud 112 out through the openings 332, thereby ensuring a lower ozone concentration. In this way, the cooling manifold 270 ensures that any ozone generated by operation of the UV lamps 140 is safely evacuated.
The cooling manifold 270 ensures that the air 330 is more evenly distributed along the length of the UV lamp 140. Thus, the cooling manifold 270 ensures effective and efficient cooling of the UV lamp 140.
Referring again to fig. 28, a discharge port 340 may be formed in the shroud 112. The exhaust port 340 may be at an end of the shroud 112 opposite the port 120. Additional discharge ports 340 may be formed in the shroud 112. The discharge port 340 may be formed in various other areas of the shroud 112. The exhaust port 340 is configured to allow air and ozone to be exhausted from the shroud 112.
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 in fluid communication with the interior of the shroud 112, such as through one or more delivery tubes. The exhaust manifold 342 may be along both sides of the shroud 112. The exhaust manifold 342 allows the air within the shroud 112 and any ozone generated to be uniformly expelled out of the shroud 112.
Each exhaust port 340 may include a cap 346 having an open end 348. An aperture 350 is formed through open end 348.

Figure 32 shows a schematic block diagram of a disinfection system 300 coupled to a fan 400 and an ozone scrubber 402, according to one embodiment of the present disclosure. In at least one embodiment, disinfection system 300 is distinguished from fan 400 and ozone scrubber 402. In at least one other embodiment, sanitizing system 300 comprises one or both of fan 400 and/or ozone scrubber 402, such as within a backpack assembly, a case assembly, a cart, and/or the like.
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 (e.g., one or more hoses, one or more tubes, one or more ducts, and/or the like). As described herein, the fan 400 generates an airflow that generates pressurized air into the cooling manifold 270, which cools the UV lamps 140. As described herein, disinfection system 300 may also include an exhaust subsystem 406, e.g., one or more exhaust ports, exhaust manifolds, etc.
The air cools the UV lamp 140 and is discharged through the discharge subsystem 406 along with any ozone generated. The exhaust subsystem 406 may in turn be in fluid communication with the ozone scrubber 402, for example, via one or more conduits 408. For example, the ozone scrubber 402 neutralizes, deactivates, and/or converts ozone into air. The scrubbed air may then be recirculated within the enclosed compartment by, for example, an environmental control system, an air conditioning system, or the like. Alternatively, disinfection system 300 may not be coupled to ozone scrubber 402.
In at least one embodiment, decontamination system 300 may be used to decontaminate components within an enclosed space (e.g., a cockpit of an aircraft). For example, as described herein, the disinfecting system 300 may include a cane assembly. Disinfection system 300 may be used to reduce or otherwise displace ozone concentration levels during use. For example, the backpack or case assembly of the sterilization system 300 may be placed outside of an enclosed space (e.g., a cockpit), which allows the fan 400 to draw in air. When the wand assembly is used in an enclosed space (the doors of the enclosed space may be slightly distracted by the hoses extending through it), the wand assembly discharges ozone via the exhaust subsystem 406 while cooling air is supplied to the UV lamps 140 via the cooling manifold 270. The exhaust subsystem 406 may push the exhausted air into the enclosed space and then naturally draw the air through the open door. Thus, the ozone is displaced and dissipated out of the enclosed space.
Referring to fig. 1-32, certain embodiments of the present disclosure provide a disinfecting system that includes a disinfecting head 106. The disinfection head 106 includes a UV lamp 140. The cooling manifold 270 is configured to deliver air to the UV lamp 140 to cool the UV lamp 140. In at least one embodiment, the disinfection head 106 further includes an exhaust subsystem 406 configured to exhaust ozone from the disinfection head 106.
