BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates generally to the field of air sanitizers which employ ultraviolet radiation. More specifically, the present invention relates to a magnetically attachable and networkable ultraviolet sanitizing device for sanitizing air in indoor spaces.
2. Description of the Related Art
The world has an increased awareness of infectious disease and is currently searching for ways to combat the spread of pathogenic bacteria and viruses. Due to the COVID-19 pandemic, improved sanitizing devices are not only desired, they have become a necessary element in both living and work spaces.
It is now a well-known fact that COVID-19 is transmitted by human-to-human contact and is considered to be a highly infectious disease. One of the predominant mechanisms for pathogenic agents to be contagious is self-inoculation from contaminated surfaces. Self-inoculation could occur by poor hand hygiene or by not following common disease-controlling etiquettes such as frequent hand to face contact.
In addition to transmission though contact with contaminated surfaces, respiratory particles, whether they be droplets or aerosols based on the particle size and specifically in terms of the aerodynamic diameter, are a well-known and understood means of disease transmission. It has been proven that viral disease outbreaks via aerosol transmission is a serious concern as droplets and aerosols containing bacterial and viral pathogens may remain airborne for enough time to infect susceptible people.
Air conditioning ducts pose themselves as a particular hazard when it comes to the spread of infectious disease through pathogens in droplets or aerosols. Because droplets and aerosols may remain airborne for a considerable amount of time, they may be spread throughout a building in a short amount of time. In addition to droplets and aerosols spread by coughing and sneezing, certain pathogens may be able to live and survive inside of air conditioning systems. Moreover, pathogens such as viruses and other bacteria may be spread to other spaces in a building through such ducts.
Germicidal techniques and air sanitizers are known in the art. Numerous methods inventions have been created and implemented to clean and sanitize both surfaces and the surrounding air. Among the most popular methods of sanitizing both surfaces and the surrounding air is the use of chemical sanitizers.
Chemical sanitizers for air involve the introduction of an aerosolized chemical mixture into the air. Though this method of disinfecting air has proven effective, many chemical sanitizers can irritate respiratory and integumentary systems.
As an alternative to chemical sanitizers, the use of ultraviolet irradiation devices has become widely used. Ultraviolet sanitizing devices essentially consist of a device where ultraviolet lights irradiate surfaces and the surrounding space. Such ultraviolet irradiation has proven itself highly effective in killing pathogens, and several portable devices have been created. However, irradiation of ambient air in indoor spaces has still proven problematic due to the size of current sanitizers and the lack of protection caused air movement caused by air conditioning ducts.
Presently, there exists a need for an improved, low maintenance, magnetic UV LED air sanitizing system and method for sanitizing air in indoor spaces. Such a system must be able to effectively replace chemical sanitizers. Additionally, such as system must be able to insure that such a system is optimized to current health and safety standards. Furthermore, such a system should produce an increased amount of sanitized air while providing an easy-to-use system which may be networkable with other internet enabled devices.
SUMMARY
The present invention is directed to an improved UV LED air sanitizing system and method for sanitizing air in indoor spaces. Such a system can effectively replace the use of chemical sanitizers in indoor air spaces. Use of the magnetically attachable UV LED sanitizer is conducive to an institution's compliance with current health and safety standards. Moreover, the magnetically attachable UV LED sanitizer system is capable of producing an increased amount of sanitized air while providing an easy-to-use system which may be networkable with other internet enabled devices.
An object of the present invention is to provide an improved UV sanitizing system which can be specifically configured to sanitize air entering, travelling through, and exiting existing heating, cooling and air conditioning ductwork. The invention is shaped and configured to magnetically attach to air conditioning vents and ducts providing a user a portable, but reliable air sanitizing system which can be used for spaces such as offices, homes, hotel rooms, hospital rooms, and other indoor spaces where sanitized air is desired. The magnetically attachable UV LED air sanitizing system model is equipped with a rechargeable lithium battery. The system uses at least one magnet for attaching to ferromagnetic surfaces such as, but not limited to, air conditioning ducts, vents, registers and grilles.
The magnetically attachable UV LED sanitizer system consists of one or more UV LED sanitizer system units, each unit comprising an outer shell assembly consisting of a rectangular cuboid outer machine shell, a front plate, and a back plate shaped in such a manner so as to fit inside an air conditioning duct register, diffuser or grille; a transparent cover, said cover allowing for the transmission of germicidal ultraviolet light frequencies; an ultraviolet lamp board; a motion detector capable of detecting movement of persons in an indoor space which, upon detection of motion, sends an electric signal to the at least one processor which can turn the ultraviolet lamp board; at least one processor; a power supply; a rechargeable battery; a wireless network card; a magnet assembly, said magnet assembly positioned on the opposite side of the transparent cover so as to attach to ferromagnetic surfaces such as air conditioning ducts, registers, diffusers and grilles; and memory storing computer readable instructions that, when executed by the at least one processor, cause the magnetically attachable UV LED sanitizer system to irradiate a space with germicidal UV radiation from the said ultraviolet lamp board.
Compared with other UV LED light sanitizer products, the present invention not only inhibits the growth of pathogens such as bacteria and viruses, but also can be conveniently attached to metal surfaces such as a central air-conditioning tube. As a method of operation, the UV disinfection can be carried out remotely and at regular intervals through wireless networks. In some embodiments, a motion sensor detects human body movements so as to activate the UV LED sanitizing system to protect the person when she or he enters a room. The magnetically attachable UV LED sanitizer system is easy to install and disassemble. The magnetically attachable UV LED sanitizer system is also convenient for intelligent control to adapt to user needs which allows for a healthier living environment.
A further object of the invention is to provide a system which is capable of sanitizing a greater amount of air than existing UV LED sanitizer systems. The present invention is designed to attach to heating, ventilation and air conditioning (HVAC) ducts so as to create a system which sanitizes air moving into, through or from HVAC systems. Moreover, the invention uses a light emitting diode board which is capable of emitting a greater amount of germicidal UV radiation as well as a lamp board which is capable of withstanding higher operating temperatures. The present invention can be used for household epidemic prevention, sterilization, and inhibition of viruses and bacteria. It can be effectively used in shopping malls, office buildings, stations, airports and other public places having typical air conditioning systems.

The exemplary magnetically attachable UV LED sanitizer will now be described in detail with reference to embodiments thereof as illustrated in the accompanying drawings. Unless otherwise indicated illustrations in the figures are not necessarily drawn to scale.
FIG. 1 is a perspective illustration of an exemplary magnetically attachable UV LED sanitizer in accordance with an embodiment of the invention. At its essence, the magnetically attachable UV LED sanitizer system comprises a power supply 110, an outer shell 120 and an LED lamp board 130. In the preferred embodiment of the invention, the power supply consists of a 12-volt rechargeable lithium ion battery system. Persons having skill in the art will understand that such a battery system is rechargeable through numerous AC power supplies. The lithium-ion battery system may consist of one or more rechargeable cells, preferably with a high capacity rating. In embodiments of the invention, the power supply 110 may consist of a 110 volt or 220 volt external supply known and appreciated in the art. Persons skilled in the art will readily appreciate that numerous power supply options are available to charge batteries and power the device in locations where power supply parameters such as voltage may vary. In alternative embodiments, the power supply may come from a Universal Serial Bus (USB) cable which is networkable with numerous electronic devices understood in the art.
The outer shell 120 is made of a rigid metal alloy material such as, but not limited to, polished aluminum alloy. Alternatively, the outer shell may be made from an ABS plastic material configured to fix and protect the internal accessories. Persons having skill in the art will understand that numerous materials may be used to create an outer shell. It will be understood by persons having skill in the art that the primary objects of the outer shell are to provide for protection of the inner components and to create an object shape which is conducive for fitting inside air conditioning vents, ducts,
The LED lamp board 130 consists of a plurality of ultraviolet light emitting diodes (LEDs). In one embodiment, the LED lamp board contains 24 UV emitting LEDs. However, the number of LEDs can vary depending on factors such as unit size and ultraviolet germicidal radiation demand
FIG. 2 is an exploded perspective view of a magnetically attachable UV LED sanitizer in accordance with an embodiment of the invention. In addition to a power supply 110, an outer shell 120 and an LED lamp board 130, the invention further comprises a quartz glass cover board 205, a motherboard bracket 210, a motion detector controller board 215, a microprocessor board with wireless networking board 220, a battery 225, a battery bracket 230, a front plate plug 235, a front patch 240, a back plate plug 245, a back patch 250, one or more shell silicone pads 255, and one or more magnets 260 capable of attaching to ferromagnetic surfaces.
The LED ultraviolet lamp board has a transparent cover 205 superior to or in front of the LED lamp board for encapsulation and protection. The transparent cover allows for the transmission of germicidal ultraviolet radiation. In embodiments of the invention, the transparent cover can be made any suitable material ranging from quartz glass to a transparent plastic. The object of the transparent cover is to protect the LED lamp board while allowing a maximum amount of germicidal radiation to pass through.
The microprocessor board with wireless networking board 220 includes at least one processor and is held in place by a motherboard bracket 210. In embodiments of the invention, the at least one processor is a microcontroller unit (MCU) capable of performing programmable instructions that is known and appreciated in the art. The microprocessor board with wireless networking board allows for networking with mobile devices such as, but not limited to, smartphones and tablets. By way of example, and not limitation, a user may access a software application on a mobile device which is capable of transmitting signals to the MCU which controls the operation of the LED lamp board 130. It is to be understood that the microprocessor board includes memory storing computer readable instructions that, when executed by the at least one processor, cause the magnetically attachable UV LED sanitizer system to irradiate a space with germicidal UV radiation from the said ultraviolet lamp board.
A motion detector controller board 215 is also included in the invention. Persons having skill in the art will understand that a motion controller board is governed by a sensor which detects motion in a given space. In the present invention, a person need only enter a room for the motion detector to activate the LED lamp board or send a signal to a networked device via a microprocessor board wireless networking board 220 and receive instructions by the same network. When a moving object approaches the magnetically attachable UV LED sanitizer unit within a general radius of 2-3 meters, the sensor sends the signal to the main board processor. After the at least one processor on the microprocessor board with wireless networking board 220 receives a signal from sensor, an red indicator light will be on. At this time, the at least one processor will send a signal to a timer, which will temporarily turn off the UV light for 8-10 seconds. After 8-10 seconds, if there are moving objects near the product, it will continue to be off and waiting for the next 8-10 seconds. If the sensor does not detect a moving object within 8-10 seconds, the motion sensor will send a signal to the microprocessor board wireless networking board 220, and the product will return to its previous working state.
In the preferred embodiment of the invention, the LED lamp board 130 is formed through aluminum substrate processing. Such aluminum substrate processing provides for improved heat dissipation. In embodiments of the invention, the LED core material is a flat-type indium gallium nitride (InGaN) light emitting diode. Novel flat-type indium gallium nitride (InGaN) LEDs are capable of emitting radiation at greater intensities for greater distances. Persons having skill in the art will appreciate that other suitable materials known and appreciated in the art may be used. In the preferred embodiment of the invention, the LEDs produce germicidal UV radiation at a wavelength between 270 and 280 nanometers. For embodiments of the invention, the effective germicidal radiation distance is 50 centimeters with an irradiation angle from the LED lamp board being 120 degrees.
FIG. 3 is front elevation view of an exemplary magnetically attachable UV LED sanitizer in accordance with an embodiment of the invention. Persons having skill in the art will readily appreciate that the rectangular shape of each unit allows for the convenient placement in air conditioning vents, ducts, registers and on or inside grilles.
The LED ultraviolet lamp board is powered and charged by the power board itself. When there is no connection to an external power source, the battery independently supplies electricity to the power board and the remote control board to supply power to the ultraviolet lamp board and the motion detector. The power board plus the remote control board can remotely control the disinfection device through various wireless networking methods.
In embodiments of the invention, the LED ultraviolet lamp board has quartz glass in front of the lamp board for encapsulation and protection. The ultraviolet light source can transmit through the glass for ultraviolet disinfection. The mainboard bracket in the housing is a fixed LED ultraviolet lamp board and power board plus WIFI board and radar board with a shell silicone pad. It acts to buffer the friction when the magnet is attracted. The battery bracket in the casing is used to fix the internal lithium battery as the aluminum front and rear plugs are used to fix the connection between the mainboard bracket and the socket bracket. The aluminum front and rear patches are used to decorate and protect the aluminum plate front and end plugs.
FIG. 4 illustrates a typical computer system 400 that, when appropriately configured or designed, may serve as a microprocessor board with wireless networking board 220 system for which the magnetically attachable UV LED system, and the components thereof, may be embodied.

The CPU 410 may be of various types including micro-controllers (e.g., with embedded RAM/ROM) and microprocessors such as programmable devices (e.g., RISC or SISC based, or CPLDs and FPGAs) and devices not capable of being programmed such as gate array ASICs (Application Specific Integrated Circuits) or general purpose microprocessors. As is well known in the art, primary storage 420 acts to transfer data and instructions uni-directionally to the CPU and primary storage 430 typically may be used to transfer data and instructions in a bi-directional manner. The primary storage devices discussed previously may include any suitable computer-readable media such as those described above. A mass storage device 440 may also be coupled bi-directionally to CPU 410 and provides additional data storage capacity and may include any of the computer-readable media described above. Mass storage device 440 may be used to store programs, data and the like and typically may be used as a secondary storage medium such as a hard disk. It will be appreciated that the information retained within mass storage device 440, may, in appropriate cases, be incorporated in standard fashion as part of primary storage 420 as virtual memory. A specific mass storage device such as a CD-ROM 450 may also pass data uni-directionally to the CPU. It will be further appreciated by persons having skill in the art that memory storing computer readable instructions that, when executed by the at least one processor, cause the automated till register system by at least one processor cause the operation of the LED lamp board.
CPU 410 may also be coupled to an interface 460 that connects to one or switches or other well-known input devices such as mice, keyboards, touchpads and even other computers. Finally, CPU 410 optionally may be coupled to an external device such as a database or a computer or telecommunications or internet network using an external connection shown generally as a network 470, which may be implemented as a hardwired or wireless communications link using suitable conventional technologies. With such a connection, the CPU might receive information from the network, or might output information to the network in the course of performing the method steps described in the teachings of the present invention. Persons having skill in the art will understand that the LED lamp board 130 is coupled to such an interface.
FIG. 5 illustrates a general network diagram to which the magnetically attachable UV LED sanitizer system may be successfully implemented. In one embodiment, the network 500 may operate as the Internet or the World Wide Web (WWW). It will be understood by those skilled in the art, though, that communication with the network may take many different forms. Non-limiting examples of forms for communication system include local area networks (LANs), wide area networks (WANs), wired telephone networks, wireless networks, or any other network supporting data communication between respective entities. In the preferred embodiment of the invention, the magnetically attachable UV LED sanitizer system connects to the network through IEEE 802.11 wireless local area network protocols commonly referred to as Wi-Fi. A network may include servers which are capable of providing software or firmware instructions to each magnetically attachable UV LED sanitizer unit as needed.
In embodiments of the invention, the exemplary magnetically attachable UV LED sanitizer unit is networkable with tablets 510, desktop computers and servers 520, and smartphones 530.

Furthermore, persons having skill in the art will appreciate that the exemplary magnetically attachable UV LED sanitizer system can be configured to network with devices such as, but not limited to, security cameras 540, web cameras 550 and microphones 560. Persons having skill in the art will readily appreciate that software applications can be developed and implemented on computer platforms ranging from, but not limited to, tablets, smartphones, desktop, laptop and server systems to operate a magnetically attachable UV LED sanitizer system over such a network.
FIG. 6 illustrates a magnetically attachable UV LED sanitizer unit 100 attached to and fitting in an air conditioning register 600. Persons having skill in the art will appreciate that the magnetically attachable UV LED sanitizer system may operate in a wide variety of air conditioning ducts, vents, grates and registers. As air flows in, though, and from such ducts, vents, grates and registers, the air passes through a field of germicidal ultraviolet radiation. Such radiation is capable of sanitizing particulates, droplets and aerosols in the travelling air providing sanitized air for indoor spaces.
Use of the magnetically attachable UV LED sanitizer system is designed to be simple and efficient. Use of the magnetically UV LED sanitizer system involves a user connecting the one or more magnetically attachable UV LED sanitizer system units to a wireless network, a user affixing the one or more magnetically attachable UV LED sanitizer system units inside an HVAC duct, register, diffuser and/or grille, a user remotely controlling the one or more magnetically attachable UV LED sanitizer system units over a wireless or wired network, and sanitizing air in indoor spaces using one or more of the said magnetically attachable UV LED sanitizer system units to irradiate air passing into, through or from the said HVAC duct, register, diffuser and/or grille. Persons skilled in the art will readily appreciate that each of the UV LED sanitizer system units can be remotely controlled with a tablet, smartphone or other networked device. Persons skilled in the art will further appreciate that the UV LED sanitizer system units can also be controlled by a motion detector capable of detecting movement of persons in an indoor space which, upon detection of motion, sends an electric signal to the at least one processor which can turn the ultraviolet lamp board.
