Description

[Technical Field]

[0001] The present invention relates to a multiple linear grating GUV LED fluid sterilization technology, and more particularly to a multiple linear grating GUV LED fluid sterilization method and sterilization space device for rapid disinfection, sterilization, and high-flow purification of fluids. [Background technology]

[0002] UV LEDs (Ultraviolet Light-Emitting Diodes), which emit invisible ultraviolet light, are used as a powerful disinfection and sterilization tool for, for example, disinfecting drinking water and food and beverage products. Disinfection by ultraviolet radiation is considered an ideal disinfection method because it is safe and does not cause secondary contamination such as AOC and DOC, without the need for drugs or chemicals, and can disinfect efficiently. Summary of the Invention [Problem to be solved by the invention]

[0003] However, currently known UVC LED disinfection and sterilization devices have many drawbacks. 1. First, not all UV rays can effectively disinfect and sterilize. UV light must be in the light absorption band of the DNA or RNA of pathogens, and only when it can absorb this photon can it perform its chemical function. 2. The absorbed radiation dose must be sufficient to dissolve or break DNA or RNA strands, which will inactivate the pathogen and make it no longer infectious, or decompose and eliminate it. Therefore, the wavelength band of 234nm to 313nm, which is absorbed by DNA or RNA, contains only a small portion of UVB and UVC, making it the most effective sterilization band, and is called GUV (Germicidal Ultraviolet) radiation sterilization light. Additionally, UV LEDs have the following drawbacks: a. Regarding the UV LED light emission angle θ, the angle at which the LED light intensity decays from its peak to 50% has a uniform tolerance of 50% or more. However, due to the large difference in the position of the radiation environment, it is difficult to prevent fish from leaking from the net-swallowing boat and increase the sterilization rate. b. A large irradiation angle causes scattering of radiation, and since general LED light is a 3D diverging cone with a large area, the intensity per unit area of ​​radiation is weak. As a result, this radiation cannot effectively purify fast-flowing fluids. Since K=I×t, if the radiation dose I is low, it takes an increasing time t to accumulate to the dose K value that inactivates pathogens. c. If the radiation angle is not controlled, ultraviolet rays may leak out of the disinfection area, causing ultraviolet environmental pollution, which may cause injury to the human body when it comes into contact with the area. d. Currently, most UV LED disinfection and sterilization devices are parallel to the fluid direction, and the radiation intensity is inversely proportional to the square of the distance. This results in a relatively low energy efficiency for accumulating radiation, and the radiation intensity cannot be accumulated quickly enough to cause lethal effects, resulting in a relatively low fluid treatment efficiency. e. The effective application of reflected light is poor. Current UV LED designs mainly use matrix arrays, where the radiation is parallel to the fluid and there is no reflection design, so the radiation dissipates after only one use, resulting in a waste of radiation energy. Thus, in the case of non-fluid sterilization, such as the surface sterilization of stationary objects, the problem of batch processing is that the radiation intensity can be accumulated over time, so there is no significant problem with sterilization of stationary objects when irradiated for a long time, but for fluids that flow and require continuous processing, such as air or water, a huge flow rate must be processed in a short time, and it is not possible to wait for the fluid to stagnate and accumulate sufficient sterilization energy, which poses a problem in sterilization rate. Moreover, all fluid disinfection is a continuous process that requires the use of an open space, and if light leakage cannot be controlled, the radiation is likely to damage human skin and eyes. The ultraviolet light emitted by conventional UV LED disinfection and sterilization devices has uneven radiation intensity and is insufficient in strength, making it impossible to meet the rapid and high-flow sterilization requirements of fluids. Therefore, there was a need to provide a highly efficient and safe technology. [Means for solving the problem]

[0004] To solve the above problems, the main objective of this invention is to use a design with two Maddox Rod radiation paths. First, the GUV LED radiation passes through a cylindrical lens to form a linear 2D sterilization grating projection light perpendicular to the direction of the cylindrical lens, which is then introduced into the sterilization space through a viewing window and reflected by a columnar reflector on the inner surface of the sterilization space. Second, the Maddox Rod reflection and counter-reflection form multiple linear grating GUV LED radiation. The fluid sterilization method of the present invention forms an effective sterile space chamber within a hollow cylindrical tube, and sterilizes water flowing through the sterile space, thereby forming a sterile space chamber for water. In another fluid sterilization method of the present invention, the fluid is air, and the air is sterilized by flowing through the sterile space device, thereby forming an air sterilization device. Yet another method of the present invention involves delivering sterilized clean air between a mask, a mouth-nose cover, a face shield and the nose to form a positive pressure mask. To achieve the above objectives, the present invention provides a linear grating GUV LED fluid sterilization method and sterilization space device. The linear grating GUV LED lamp bead is packaged with an arc-shaped cylindrical lens. The arc-shaped cylindrical lens is a cylindrical lens with a concave arc, a convex arc, a continuous concave column, or a continuous convex column. The UV light emitted by the linear grating GUV LED lamp bead passes through the arc-shaped cylindrical lens coated on its end surface. When the radiation passes through a plane perpendicular to the cylindrical axis, the divergence rate remains unchanged, but it undergoes unequal refraction at other surfaces, ultimately forming rays perpendicular to the cylindrical axis. These parallel rays extend outward to form a light plane, called a linear grating plane. In other words, while the conventional emission angle is a 3D spherical divergence, the arc-shaped cylindrical lens generates 2D radiation rays on the vertical plane, and these rays form many parallel light planes on the vertical cylindrical plane, like a cross section of a linear grating. The radiation intensity is inversely proportional to the square of the distance, and the difference between the 2D and 3D distance-area ratios is significant. The radiation intensity of the grating GUV LED of the present invention is much stronger than that of a typical UVC lamp bead. The radiation light is emitted linearly and irradiated from the outside to the inside through a viewing window pre-installed on the side of the sterilization space device, entering the sterilization space chamber, perpendicular to the light incident on the cross section. The second light path is designed to be irradiated onto a highly reflective columnar object. The reflected light is again reflected by the continuous columnar reflector on the inner surface of the sterilization space chamber, and its path is also perpendicular to the continuous columnar reflector, just like the linear grating surface. The incident light and the reflected or anti-reflected light inside the chamber are in the same quadrant. The parallel multiple linear grating surface lights increase the radiation overlap rate, which enhances the radiation and allows the radiation to be reflected in a closed environment. Based on the principle of closed-system Samna radiation irradiation, assuming a metallic aluminum reflectance of R=90% for the UVC band, calculation is: E=ED+ER, where ED is the original irradiance and ER is the reflected irradiance. ER=ED×(R / (1-R)), E=total irradiance = 1 (original light source) + 9 (superimposed reflections) = 10. In this way, by placing one GUV equivalent to the irradiance of 10 GUVs, the reflected radiation can be reused, which is beneficial for rapid sterilization needs.The radiation is uniformly distributed through superposition, and the overlapping use of highly reflective light increases the radiation intensity, resulting in high sterilization efficiency. This is the first advantage of the device of the present invention. The 2D linear grating surface allows the direction of the radiation path to be controlled, and the radiation is reflected only vertically along the columnar reflector, toward the columnar cross section. This controlled radiation direction prevents leakage and environmental pollution. This is the second advantage of the device of the present invention. Another advantage of UV sterilization is that, although no UV-resistant pathogens have yet been discovered on Earth, the radiation traveling in a straight line makes it easy for pathogens to hide. Although the incident light, reflected light, and retroreflected light are in the same quadrant, the angle of the reflected radiation constantly changes direction, resulting in the retroreflected light also changing multiple times, eliminating the drawback of light traveling at a fixed angle in a straight line. The method of the present invention creates an omnidirectional radiation angle, leaving pathogens with no escape route and eliminating them, thereby improving sterilization efficiency. This is the third advantage of the device of the present invention. UVC alone is not enough to sterilize. Microorganisms are divided into capsular and non-capsular types, and since capsules are made of protein, their absorption peak is at 220 nm. 220 nm UVC destroys the protein and can sterilize. However, it is ineffective against non-capsular pathogens. The GUV of the present invention has a DNA absorption wavelength range (234 nm to 313 nm), and pathogenic bacteria always contain DNA. This makes it the optimal sterilizing ultraviolet GUV, which is the fourth effect of the present invention. These are all effects and features of the method of the present invention. In the linear grating GUV LED lamp bead of the present invention, the end face is covered with an arc-shaped cylindrical lens, and the arc-shaped cylindrical lens may be packaged with one of a convex arc-shaped pillar, a concave arc-shaped pillar, a continuous convex arc-shaped pillar, or a continuous concave arc-shaped pillar. The material of the pillar lens of the linear grating GUV LED lamp bead of the present invention may be one of UV-transmitting materials such as quartz, fluorine-containing polymer, polydimethylsiloxane (PDMS), polyimide (PI), etc., forming the GUV LED linear grating lamp bead packaged with an arc-shaped cylindrical lens. Another embodiment of the present invention includes a viewing window that allows any UV light to be irradiated from the outside into the highly sterilized space chamber. The viewing window may be made of UV-transmitting quartz or a hole and can be connected to a linear grating GUV LED lamp bead. The linear grating radiation enters the sterilized space chamber from the side. The chamber is made of a hollow quartz tube, the outer wall of which is made of highly reflective aluminum or a quartz tube. The aluminum vacuum deposition layer on the outer surface may have a viewing window pre-installed to allow the GUV LED to pass through, or it may be processed with highly reflective aluminum metal. The radiation entering through the viewing window on the side strikes the highly reflective columnar element, again forming a multiple linear grating reflective layer. The reflective layer and anti-reflective layer are both linear grating radiation, and the radiation is in the same quadrant, increasing the radiation overlapping opportunity, thereby enhancing the radiation light and improving light uniformity. This sterilized space device is configured in this way. The multiple linear grating GUV LED fluid sterilization device of the present invention includes one or more linear grating GUV LED lamp beads, which modify the GUV LED sterilizing light into a 2D linear transmission to enhance radiation intensity. In at least one embodiment, the linear grating GUV LED lamp beads of the present invention can be connected in series, parallel, or arrayed. The DC power supply is supplied by a general power source or battery of DC 24V or less and is used to control the power supply of the PCB board and to light the linear grating GUV LED lamp beads or the fan. The present invention's concave arc-shaped linear grating GUV LED lamp bead has a pre-installed viewing window on the outside of the quartz tube, and the hollow quartz tube is joined to the cylindrical end of the concave arc-shaped cylindrical lens, so that the horizontal axis of the sterilization chamber is parallel to the horizontal axis of the arc-shaped cylindrical lens. Except for the joint of the curved end of the arc-shaped cylindrical lens, which forms the outer wall of the transparent viewing window, the other outer wall of the quartz tube has an aluminum metal UV reflective surface coating or a vacuum-deposited aluminum reflective layer, and the sterilization chamber has openings on both ends to allow fluid to flow into the sterilization chamber, forming a space device for multiple linear grating GUV LED fluid disinfection and sterilization. The linear grating GUV LED lamp bead of the present invention is connected to a sterilization chamber made of aluminum metal material. The inner surface of the hollow aluminum tube wall is one of a continuously convex or continuously concave arc-shaped columnar reflector, with openings on both end faces. The hollow inner tube wall is one of a circular, rectangular, or square shape, with an inner diameter or hole diameter of 30 mm or less, and a hole pre-installed on one side to serve as a viewing window for installing the linear grating GUV LED lamp bead. The viewing window may be one or more, and the linear grating GUV LED lamp bead irradiates radiation into the sterilization chamber through the hole, irradiating from the outside to the inside to form an emissive grating surface whose cross section is perpendicular to the columnar reflector. The reflected and anti-reflected radiation have different phases, but are multiplexed perpendicular to the columnar cross section and in the same cross-sectional quadrant, increasing the radiation overlap rate and making the radiation intensity stronger and more uniform, resulting in a multiple linear grating GUV LED fluid sterilization chamber. As in the above example, a transparent quartz tube is fitted inside the hollow aluminum tube as a viewing window for the linear grating GUV LED lamp beads. The linear grating GUV LED lamp beads radiate radiation through this hole into the quartz tube and enter the sterilization chamber of the quartz tube. The radiation is then radiated from the outside to the inside, forming a radiative grating surface with a cross section perpendicular to the columnar reflector. The reflected or retroreflected radiation is reflected by the continuous columnar reflector coated on the outside with aluminum and re-enters the sterilization chamber. Although the reflected and retroreflected light have different phases, they are both perpendicular to the columnar cross section and in the same cross-sectional quadrant, increasing the radiation overlap rate and making the radiation intensity stronger and more uniform. For aqueous sterilization chambers, the inner diameter of the chamber is limited to 30 mm. GUVs have high energy but low transmittance, and ions such as calcium, magnesium, silicon, oxygen, and nitrogen are always present in water, which significantly affect GUV transmittance and ensure sterilization efficiency. The linear grating GUV LED lamp bead device of the present invention includes a plurality of linear grating GUV LED lamp beads, the lamp bead may be one or more, and the plurality of GUV LED lamp beads may be arranged on the same side or different sides of the sterilization space to enhance the radiation intensity. The wavelength of the linear grating GUV LED lamp bead of the present invention is between 234nm and 313nm. According to Einstein's photon theorem, dissolving the DNA or RNA of pathogens is related to the absorption band of the light wave. The absorbed photon undergoes chemical energy conversion, dissolving and breaking the chemical bonds of the DNA or RNA, causing the broken DNA or RNA to become inactive, which is called disinfection and sterilization. According to the International Commission on Illumination (CIE) publications, the absorption peak is at 265nm and the valley is between 234nm and 313nm. The linear grating UV sterilization band of this patent, which is 234nm to 313nm and is called GUV LED, includes some UVC and some UVB wavelengths. It is modified by a cylindrical lens and linearly modifies the emitted light based on the Maddox rod transmission principle. Since the light source is not a single point, multiple points of the light source form multiple parallel linear projections, which is called linear grating projection, and forms the linear grating GUV LED lamp bead of the present invention. The present invention also provides a system including the linear grating GUV LED fluid sterilization device. In at least one embodiment, the system further includes an air extraction mechanism and a front-edge filter, which actively draws in air and passes it through the sterilization space chamber of the multiple linear grating GUV LED lamp beads. The air first passes through the filter to remove granular foreign matter, then enters the hollow chamber of the sterilization space, where it is exposed to ultraviolet light for sterilization. The purified air then passes through a nose sleeve into one of a mask, respirator, nose cover, face shield, head cover, or jumpsuit, forming a positive pressure mask for use by people. In another embodiment, the sterilization device of the present invention is installed at the air outlet of a person wearing a protective cover, which is made of an impermeable polymer and has an air or oxygen inlet, creating positive pressure within the protective cover and discharging used air through the air outlet. Before the waste air leaves the protective cover, it must first pass through the multiple linear grating GUV LED fluid sterilization device, allowing the sterilized air to return to the environmental space, creating a contamination- and germ-free environment. The present invention also provides a linear grating GUV LED fluid sterilization method and sterilization space device. In at least one embodiment, the fluid sterilization space device is used for sterilizing aqueous liquids, and is disposed or combined with, for example, a faucet, a drinking fountain, a water outlet, a drain, a sewage treatment device, a waste liquid treatment device, or a medical waste liquid treatment device. In at least one embodiment, the fluid treatment device further includes a filter installed at the upstream end of the disinfection and sterilization space. Therefore, the GUV LED device is an air fluid treatment device that can be used as a disinfector, sterilizer, purifier, or sterilizer. The present invention provides a multiple linear grating GUV LED fluid sterilization method, the steps of which include: 1. Start the DC power supply: The power pack can be a general power supply or battery of DC 24V or less, and can send power to the control power PCB board through the power supply contact. 2. Linear grating GUV LED lamp beads: The linear grating GUV LED lamp beads are turned on to emit ultraviolet radiation of 234~313nm, which is then emitted parallel to each other through a cylindrical lens to form a linear grating surface. 3. Radiation viewing window device: The viewing window device is located on the side of the sterilization chamber and can be a quartz viewing window through which the GUV passes or a hole through which a pre-installed GUV LED emits radiation, and the radiation is irradiated from the outside to the inside and enters the sterilization chamber vertically. 4. Sterilization chamber: The device is open at both ends, the inner surface is a columnar reflector, and a viewing window is pre-installed on the side to allow radiation to enter. The GUV radiation light is reflected and re-reflected by multiple linear gratings on the inner surface of the sterilization chamber. The fluid to be treated enters the sterilization chamber from one end in the flow direction and undergoes sterilization exposure treatment. The sterilized fluid is discharged from the outlet end of the sterilization chamber. In the linear grating GUV LED fluid sterilization method completed through these steps, the radiation enters the sterilization space chamber from the side, and its reflection path is perpendicular to the columnar structure of the sterilization space chamber. Therefore, the radiation direction of the UV light inside the sterilization space forms parallel linear grating surfaces perpendicular to the column axis, and is repeatedly reflected by the columns inside the chamber and all ends up in the same quadrant. The overlapping of the radiation increases the probability, thereby increasing the radiation intensity, and the multiple overlaps also result in better radiation uniformity. Furthermore, because the radiation paths are all perpendicular to the columns of the chamber, the UV light is restricted to within the sterilization space chamber, preventing UV light leakage and environmental pollution due to secondary radiation. The present technology can be used in faucets, drinking fountains, water outlets, drains, sewage treatment systems, waste treatment systems, and sterilization systems for fluids such as medical waste liquids, breathing air or oxygen, or medical waste gases. The main body of the sterilization space device of the present invention functions to allow fluids to pass through and also acts as a space that keeps the GUV LED sterilization light within the sterilization space, preventing UV light leakage and environmental pollution. While GUV LED sterilization light can sterilize and is not resistant to chemicals, it can also harm human skin and eyes. Therefore, the best way to apply GUV LED sterilization light is to perform the sterilization process inside the sterilization space device, while preventing the GUV LED sterilization light from being exposed to air and causing harm to the human body. The present invention is characterized by its short processing time, high flow rate, and ability to control leakage of GUV LED sterilization light in an open space, even when continuously flowing air or water needs to be treated. In the sterilization space device of the present invention, the GUV LED sterilization light source is first modified by a cylindrical lens, which orients the light perpendicular to the arc-shaped cylindrical lens to form a linear grating, which then exits through a viewing window on the side of the fluid sterilization space chamber. The radiation enters the sterilization space chamber from the outside in, and the GUV LED sterilization light is then modified a second time by a reflective columnar linear grating, forming multiple parallel linear grating surfaces within the sterilization space chamber. In the sterilization space chamber, the GUV LED sterilization light is reflected in the direction of the transverse columnar surfaces. Because the angle of incidence of each grating surface is different, the direction of the retro-reflective grating surface also changes, but the light reflection direction is always transverse to the columnar direction and remains parallel to each other, referred to as the GUV LED multiple linear grating surface. The GUV LED sterilization light is retro-reflected multiple times, all in the same quadrant, increasing the radiation overlap rate, uniforming the radiation, and increasing the radiation intensity. When the GUV LED sterilizing light is reflected internally, the angle of the reflected light changes many times as the incident angle changes, providing 360-degree coverage of GUV light, leaving no escape route for pathogens hiding in dust, ensuring that no pathogens remain unsterilized. This is the effect of the sterilization space device in the method of the present invention. The present invention provides a multiple linear grating GUV LED fluid sterilization method and its sterilization space device. Using its air treatment, disinfection, and inactivation properties, the treated air is delivered to the face shield, mask, or nose cover through a nasal sleeve via an exhaust mechanism and a blower mechanism. The clean air enters and creates positive pressure around the mouth and nose, preventing viruses from entering the mouth and nose due to negative pressure. The positive pressure oxygen helps oxygen enter the lungs, and the high-concentration carbon dioxide and waste heat energy exhaled from the lungs are quickly expelled from the mask due to the positive pressure, protecting the health and comfort of the mask wearer. Furthermore, impermeable sealed face shields, masks, and nose covers are collectively called protective covers, and the sterilization space device of the multiple linear grating GUV LED sterilization method of the present invention is attached to the exhaust air outlet of the protective cover, and further, exhaust containing pathogens from the wearer is processed and sterilized before being discharged, preventing infection to others, and is worn by patients with colds, pulmonary tuberculosis, avian influenza, new coronavirus pneumonia, etc. The multiple linear grating GUV LED sterilization method and sterilization space device of the present invention treats the water to obtain disinfection and sterilization properties, and can be applied to the drinking water outlet to become a flowing water treatment device. Furthermore, by connecting it to an apparatus, the amount of water treated can be increased and used for washing food or bathing at home. Furthermore, it can be installed in drains that are at risk of contamination, such as medical wastewater, to disinfect and inactivate it, and can be used as a device to reduce the contamination of pathogenic bacteria in dentist's mouthwash water, for example. [Effects of the Invention]

[0005] The advantages and positive effects of the present invention compared with the prior art are that the multiple linear grating GUV LED fluid sterilization method and sterilization space device of the present invention control and process the fluid sterilization work within the sterilization space chamber, which includes a linear grating radiation gain intensity optical lamp bead design, and uses the linear grating 2D sterilization light to irradiate the high UV reflectivity material from the outside to the inside, and uses the columnar linear grating reflective or anti-reflective radiation to coexist in the same quadrant area, increasing the opportunity for radiation overlap, enhancing the radiation dose within the sterilization space, and shortening the sterilization time. Since the radiation direction of the linear reflector device is controlled, it is less likely to leak from the sterilization space, is environmentally friendly, and does not cause environmental problems such as secondary pollution.

[0007] The present invention relates to a multiple linear grating germicial ultraviolet (GUV) LED fluid sterilization method and sterilization space device, and the related art. In order to enable those skilled in the art to fully understand the objectives, features, and effects of the present invention, the following preferred embodiments will be given in detail with reference to the accompanying drawings. 1A, 1B, 1C, and 1D show cross-sectional schematic diagrams of a linear grating GUV LED lamp bead 10 used in this embodiment. As shown in FIG. 1A, the lamp bead includes a GUV LED die 101 packaged in a lead frame substrate 100, which emits sterilizing light, i.e., ultraviolet radiation with a wavelength in the 234 nm to 313 nm band. An inner concave arc-shaped cylindrical lens 102 made of a UV-transmitting material is disposed on the packaged GUV LED die 101. Alternatively, as shown in FIG. 1B, in another embodiment, the GUV LED die 101 is packaged in the lead frame substrate 100 in the same manner. However, packaged on the die 101 is a continuous inner concave arc-shaped cylindrical lens 202. As shown in FIG. 1C, packaged on the GUV LED die 101 is an outer convex arc-shaped cylindrical lens 302 made of a UV-transmitting material. As shown in FIG. 1D, the GUV LED die 101 is packaged with a continuous cylindrical lens 402 with an outer convex arc shape. The ultraviolet arc-shaped columnar transmitting material of each of the arc-shaped cylindrical lenses 102, 202, 302, 402 is one of quartz, sapphire, fluorinated polymer, polydimethylsiloxane (PDMS), polyimide (PI), and the like. Meanwhile, the arc-shaped cylindrical lenses 102, 202, 302, 402 are packaged based on the principle of Maddox Rod transmitted light. The arc-shaped cylindrical lenses 102, 202, 302, 402 form linear light that is scattered in both directions perpendicular to the cylindrical shape of the lenses, limiting the GUV LED light angle to parallel linear 2D sterilizing light and extending it outward to form a grating surface. The grating-like radiation is irradiated onto multiple parallel light illuminating surfaces as a linear grating surface. The irradiation distance is determined by the curvature of the arc-shaped cylindrical lenses 102, 202, 302, 402. The GUV LED die 101 is packaged together with the lead frame substrate 100 to form the translucent linear grating GUV LED lamp bead 10 of the present invention. FIG. 2 is a schematic diagram of an embodiment of a linear grating GUV LED fluid sterilization space device 20 of the present invention. The linear grating GUV LED fluid sterilization space device 20 includes an outer frame 111, which may be molded from metallic aluminum or a polymer material containing aluminum powder. A viewing window 116 is formed on the side of the outer frame 111, and a linear grating GUV LED lamp bead 10 (FIG. 1A) with an internal concave arc-shaped cylindrical lens 102 is housed inside. The linear grating GUV LED fluid sterilization space device 20 includes a GUV LED fixing circuit board 106 for fixing the GUV LED. The GUV LED is fixed to the circuit board 106, and a control power PCB board 107 for managing the power supply is fixed to the control power PCB board 107. The control power PCB board 107 has a power supply contact 112, which is connected to a DC power source or a battery 113 (described later) for power supply. The inner concave arc cylindrical lens 102 of the linear grating GUV LED 10 is installed on the outer wall of the quartz tube 108. Except for the quartz viewing window 115 at the junction between the inner concave arc cylindrical lens 102 and the quartz tube 108, the entire outer wall surface of the quartz tube 108 is coated with an aluminum powder reflective layer 110 or vacuum-deposited with aluminum metal, forming an inner concave columnar reflector for radiation. The radiation is reflected by the columnar quartz tube 108, forming a linear grating surface parallel to the columnar cross section, which reflects back and forth multiple times, increasing the radiation intensity. The sterilization space chamber 103, which is a hollow chamber inside the quartz tube 108, has a diameter of 30 mm or less, and has a sterilization treatment space in the middle for passing fluids. There are openings on both ends, allowing fluids to flow through direction 109 into the sterilization space chamber 103 of the quartz tube 108. After sterilization, the fluid flows out from the outlet end 114 and can be used as a disinfection and sterilization treatment device for flowing water, drinking water, sewage, medical wastewater, etc., and can also be used for air sterilization. 3A, 3B, 3C, 3D, 3E, and 3F are cross-sectional schematic diagrams of a fluid sterilization space device according to the present invention. As shown in Fig. 3A, the linear grating GUV LED fluid sterilization space device 20 has a structure in which a sterilization space chamber is formed by plating a highly reflective aluminum on the outside of an inner cylindrical arc-shaped columnar reflector 1081 made of quartz. Alternatively, as shown in Fig. 3B, a sterilization space chamber is formed by processing an inner circular shape using metal aluminum or tetrafluoroethylene and having a continuously convex arc-shaped columnar reflector 1082. Alternatively, as shown in Fig. 3C, a sterilization space chamber is formed by processing an inner circular shape using metal aluminum and having a continuously concave arc-shaped columnar reflector 1083. Alternatively, as shown in Fig. 3D, a sterilization space chamber is formed by processing an inner rectangular shape using metal aluminum or tetrafluoroethylene. 3E, a sterilization space chamber may be used, which is machined using metal aluminum or tetrafluoroethylene and has a continuous outer convex arc-shaped columnar reflector 1085, and as shown in FIG. 3F, a sterilization space chamber may be formed by combining an inner cylindrical arc-shaped columnar reflector as shown in FIG. 3C, a movable or replaceable GUV-transmittable hollow quartz tube or hollow fluororesin tube 1081, and a continuous inner concave arc-shaped columnar reflector 1083 as shown in FIG. 3C. In one of these sterilization space chambers, the linear grating GUV LED lamp bead 10 structural structure is attached via the GUV LED hole 116 or the pre-installed quartz viewing window 115, and the diameter or width of the sterilization space chamber is within 30 mm, forming a linear grating GUV LED fluid sterilization space device 20. 4 shows a schematic diagram of an application example of the linear grating GUV LED fluid sterilization space device 20 of this embodiment. The linear grating GUV LED fluid sterilization space device 20 can be installed between the air outlet 42 and the air outlet window 41 of an air conditioner in a car or airplane, to form an air fluid sterilization device for a car or airplane. 5 shows the passive multiple linear grating GUV LED fluid sterilization space device 20 of this embodiment. The passive multiple linear grating GUV LED fluid sterilization space device 20 of this embodiment is similar to that of Example 4, except that a battery is added to the frame for co-powering, forming a passive sterilization space device 200. The passive sterilization space device 200 is attached to a protective cover 1000 made of an impermeable organic material, such as a mask, nose cover, or face shield, which already has an air supply. The cover fits close to the nose, with the exterior pierced and exposed to the open end 1001 of the protective cover 1000, leaving an exhaust port 1002 at the end. The linear grating GUV LED fluid sterilization space device 20 includes a power supply using a battery 113 added to the outer frame 111, which lights the linear grating GUV LED lamp beads 10 to irradiate the air that has entered the sterilization space chamber 103 from the side and exhaust waste air through the gas exhaust port 1002. The sterilization space chamber 103 has an air inlet 1004 for introducing air to create positive pressure inside the protective cover 1000, and has an air expansion groove 1003 formed near the mouth to provide a buffer against the rapid expansion of gas when coughing, and to process the sterilized exhaust gas containing pathogens to prevent infection to surrounding people, and is suitable for infectious disease patients or people whose work requires them to talk, preventing infection. 6 further includes a passive sterile space device 800, which includes a power-supplying active fan 802 and an air filter 803, with the battery 113 located on the same or opposite side within the outer casing 111, a GUV LED fixing circuit board 106, a control power PCB board 107, and a fluid sterile space chamber 103, one end of which is connected to the distal end of the nasal sleeve 801, and the fan 802 is located between the sterile space chamber 103 and the nasal sleeve 801. An air filter 803 is located at the other end of the sterile space chamber 103 to filter out particles in the air. The blower 802 actively draws in air, and the airflow is exposed to the linear grating GUV LED lamp beads 10, passes through the sterilization space chamber 103, and is sterilized by air-fluid sterilization treatment. The sterilized clean air is sent to the vicinity of the wearer's nostrils through the nasal sleeves 801, and is then discharged through the air outlet 808, allowing the wearer to inhale the clean air, thereby forming a fluid-driven sterilization space device. 7 to 9 are generally similar to the embodiment of Fig. 6. As shown in Fig. 7, clean air after sterilization is sent through a nasal sleeve 801 to the vicinity of the nostrils in a face shield 804, creating a positive pressure in the face shield 804, as shown in Fig. 7, clean air after sterilization is sent through a nasal sleeve 801 to the vicinity of the nostrils in a mask 805, creating a positive pressure in the mask 805, and as shown in Fig. 9, clean air after sterilization is sent through a nasal sleeve 801 to the vicinity of the nostrils in a nose cover 806, creating a positive pressure in the nose cover 806. In the embodiments shown in Figures 7 to 9, positive pressure is created within the face shield 804, mask 805, nose cover 806, etc., allowing the wearer to breathe more easily. The air is then sterilized through the linear grating GUV LED lamp beads 10 before being inhaled by the wearer of the face shield 804, mask 805, or nose cover 806. The purified, treated air is then sent into the face shield 804, mask 805, or nose cover 806, creating a positive pressure environment. During inhalation, the positive pressure allows oxygen to easily enter the lungs, preventing dizziness due to oxygen deficiency in the blood. During exhalation, the positive pressure allows waste air to diffuse easily, and carbon dioxide is rapidly diffused and expelled from the mask, further expelling water vapor and hot air, thereby helping the wearer of the face shield 804, mask 805, or nose cover 806. When the wearer inhales again, the amount of oxygen increases, the amount of carbon dioxide decreases, preventing dampness, heat, and shortness of breath, and increasing the oxygen content in the blood. The positive pressure makes it difficult for polluted air from the outside to enter the face shield 804, mask 805, or nose cover 806, protecting the wearer from infection with pathogens, and the present invention can be applied to the positive pressure safety face shield 804, mask 805, or nose cover 806. It also includes other head covers, respirators, etc. 10 shows a schematic diagram of a parallel high-capacity output embodiment of the linear grating GUV LED fluid sterilization space device 20 of the present invention. The inlet and outlet of the above-mentioned multiple linear grating GUV LED fluid sterilization space device 20 are connected to multi-port pipe joint modules 10-1 and 10-2 to increase the fluid throughput. 11 shows the linear grating GUV LED fluid sterilization method of the present invention, which includes the following steps: 11-1: Start the DC power supply device. The power pack can be a general power supply of DC 24V or less or a battery 113, and sends power to the control power supply PCB board 107 through the power supply contact 112. 11-2: Regarding the linear grating GUV LED lamp bead, the control power PCB board 107 sends power to activate the linear grating GUV LED lamp bead 10 to light up, and the linear grating GUV LED lamp bead 10 emits linear grating 234nm~313nm ultraviolet radiation through the cylindrical lens, which emits parallel to each other to form a linear grating surface. 11-3: Regarding the viewing window device for radiation entry, the viewing window device is located on the side of the sterile space chamber 103 and may be a quartz viewing window 115 through which GUV passes or a hole 116 through which pre-installed GUV LED radiation enters, so that radiation is irradiated from the outside to the inside. 11-4: Sterilization space chamber The radiation enters the sterilization space chamber 103 and is reflected again by the inner cylindrical reflector, undergoing multiple linear grating reflections and counter-reflections. The fluid to be treated enters the sterilization space chamber 103 from one end of the flow direction 109 and undergoes sterilization exposure treatment, and the sterilized fluid is discharged from the outlet end 114 of the sterilization space chamber 103.
