Abstract
Description
[Technical field]
[0001] The present invention relates to a multiple linear grating GUV LED fluid sterilization technology, more specifically, to a multiple linear grating GUV LED fluid sterilization 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 emission angle θ of the UV LED, the included angle until the LED emission intensity decays from the highest point to 50% has a uniformity tolerance of 50% or more. However, due to the large difference in the environmental positions with radiation dose, it is difficult to enhance the sterilization rate without missing any target, just like missing a big fish while trying to catch all the small ones in a net. b. A large irradiation angle causes radiation scattering. Since the general LED projection light forms a 3D divergence cone with a large area, the intensity per unit area of the radiation dose is weak. As a result, this radiation cannot effectively purify a rapidly flowing fluid. Due to K = I×t, when the radiation dose I is low, an increase in time t is required to accumulate to the dosage K value for inactivating the pathogenic bacteria. c. If the irradiation angle of the radiation is not controlled, ultraviolet rays may leak out of the disinfection area, causing environmental pollution by ultraviolet rays, which may cause harm when contacting the human body. d. Currently, most UV LED disinfection and sterilization devices are horizontal with the direction of the fluid, and moreover, the radiation intensity is inversely proportional to the square of the distance. Therefore, the efficiency of accumulating the energy of the radiation is relatively low, and the radiation intensity of a sufficient lethal dose cannot be rapidly accumulated. This results in a relatively low fluid treatment efficiency. e. The effective application of the reflected light is lacking. The current UV LED design mainly uses a matrix array, the radiation is parallel to the fluid, and there is no reflection design. Therefore, the radiation is only used once and then diverges, resulting in a waste of radiation energy. Thus, in non-fluid sterilization, such as the surface sterilization of stationary objects, regarding the problem of batch processing, the radiation intensity can be accumulated over time. Therefore, the problem of sterilizing stationary objects by long-term irradiation is not significant. However, for fluids such as air and water that flow and require continuous processing, an extremely large flow rate must be processed in a short time, and the fluid cannot stay and wait to accumulate sufficient sterilization energy. Therefore, there is a problem with the sterilization rate. Moreover, fluid disinfection is all continuous processing and an open space must be used. If the leakage of light cannot be controlled, the radiation is likely to damage the human skin and eyes. The ultraviolet rays of the conventional UV LED disinfection and sterilization devices have non-uniform radiation intensity and insufficient intensity, and cannot meet the requirements of a rapid and large-flow sterilization device for fluids. Therefore, it is necessary to provide a highly efficient and safe technology.
Means for Solving the Problem
[0004] In order to solve the above problems, the main object of the present invention is to use a design with two Maddox Rod radiation paths. The first time, the GUV LED radiation forms a linear 2D sterilization grating projection light perpendicular to the direction of the cylindrical lens through the cylindrical lens, is introduced into the sterilization space through the viewing window, and is further reflected by the cylindrical mirror on the inner surface of the sterilization space. The second time, multiple linear grating GUV LED radiation is formed by Maddox Rod reflection and anti-reflection. In the present invention, an effective sterilization space chamber is formed in the hollow cylindrical tube, and the water flowing through the sterilization space is sterilized to form a water sterilization space chamber. In the present invention, the fluid is air, and the air flows through the sterilization space device to sterilize the air, serving as an air sterilization device. In the present invention, the sterilized clean air is sent between the mask, nose and mouth cover, face shield and the nose to form a positive pressure mask. To achieve the above object, the present invention provides a linear grating GUV LED fluid sterilization space device. The linear grating GUV LED lamp beads have a package of an arc-shaped cylindrical lens, and the arc-shaped cylindrical lens is a columnar lens having a concave arc shape, a convex arc shape, a continuous concave column shape, or a continuous convex column shape. The UV ultraviolet rays emitted by the linear grating GUV LED lamp beads pass through the arc-shaped cylindrical lens coated on the end face. When the radiation passes through a plane perpendicular to the column axis, the divergence rate remains unchanged, and unequal refraction occurs on other faces, and finally, light rays perpendicular to the column axis direction are formed. These mutually parallel light rays extend outward to form a light plane, which is called a linear grating plane. That is, the conventional emission angle is 3D spherical divergence, and the arc-shaped cylindrical lens forms 2D radiation light rays on a vertical plane, and these light rays form many parallel light planes such as a cross-section like a linear grating on the columnar vertical plane. The radiation intensity is inversely proportional to the square of the distance, and the difference in the distance area ratio between 2D and 3D is large. The radiation intensity of the grating GUV LED of the present invention is much stronger than that of general UVC lamp beads. The radiation light is emitted linearly and enters the inside of the sterilization space chamber through a viewing window pre-installed on the side of the sterilization space device and irradiates from the outside to the inside. The light incident on the cross-section is perpendicular to the side. The second optical path is designed to be irradiated on a highly reflective columnar body, and when the reflected light is reflected again by the continuous columnar reflector on the inner surface of the sterilization space chamber, its path is also perpendicular to the continuous columnar reflector like the linear grating surface. The projected light, reflected light, or anti-reflected light in the chamber is in the same quadrant, and the mutually parallel multi-linear grating surface light increases the overlap rate of the radiation, the radiation is superimposed and enhanced, and the radiation is reflected in a closed environment. Based on the principle of sumna radiation irradiation of a closed system, calculating with a reflectivity R = 90% of metallic aluminum for the UVC band: E = ED + ER, where ED is the original irradiance and ER is the reflected irradiance. ER = ED×(R / (1 - R)), and the total radiation E = 1 (original light source) + 9 (superposition of reflections) = 10 is calculated. Thus, arranging 1 piece equivalent to the GUV radiation intensity of 10 pieces and reusing the reflected light of the radiation is beneficial to the need for rapid sterilization.The uniformity of radiation is homogenized by superposition, and the high-reflection light is reused to increase the radiation intensity and sterilization efficiency. This is the first effect of the device according to the present invention. The 2D linear grating surface enables the direction of the radiation path to be controllable. Only in the vertical direction of the columnar mirror, the radiation is reflected in the direction of the columnar cross-section. Due to the controlled radiation direction, it is difficult to leak and contaminate the environment. This is the second effect of the device according to the present invention. The advantage of ultraviolet sterilization is that although no virus or bacterium with UV resistance has been discovered on the earth yet, the drawback is that it is easy for germs to hide because the radiation travels in a straight line. The projected light, reflected light, and anti-reflected light are in the same quadrant, but the angle of the reflected radiation changes the direction much more than the incident angle. Therefore, the anti-reflected light also changes many times, which solves the drawback that the light only travels at a fixed angle in a straight line. According to the present invention, an omnidirectional radiation angle is formed, so that the germs lose their hiding places and are thus eliminated, improving the sterilization rate. This is the third effect of the device according to the present invention. It is not the case that any UVC can sterilize. Microorganisms are divided into those with a capsule and those without a capsule. Since the material of the capsule is protein, its absorption peak is at 220 nm. UVC of 220 nm can destroy proteins and sterilize. However, it is ineffective against germs without a capsule. The GUV of the present invention takes the DNA absorption wavelength range (234 nm - 313 nm). Since any germ must have DNA, it becomes the optimal sterilizing ultraviolet light GUV, which is the fourth effect of the present invention. These are all the effects and features of the present invention. In the linear grating GUV LED lamp beads of the present invention, the end face is covered with an arc-shaped cylindrical lens, and the arc-shaped cylindrical lens may be packaged by one of a convex arc-shaped columnar body, a concave arc-shaped columnar body, a continuous convex arc-shaped columnar body, or a continuous concave arc-shaped columnar body. The material of the columnar lens of the linear grating GUV LED lamp beads of the present invention may be made of one of ultraviolet-transmitting materials such as quartz, fluorine-containing polymer, polydimethylsiloxane (PDMS), polyimide (PI), etc., to form the GUV LED linear grating lamp beads packaged by the arc-shaped cylindrical lens. In other embodiments of the present invention, it includes a window that allows any ultraviolet light to be irradiated from the outside to the inside and enter the high-sterilization space chamber. The window may be quartz or a hole through which ultraviolet light can pass, and can be connected to the linear grating GUV LED lamp beads. The linear grating radiation enters the sterilization space chamber from the side. The material of the chamber is a hollow quartz tube, and its outer wall is combined with highly reflective aluminum or a quartz tube. In the vacuum evaporation layer of the outer aluminum, only the window is installed in advance to allow the GUV LED to pass through, or it is processed by highly reflective metal aluminum. The radiation entering from the side window hits the highly reflective columnar body and reforms the multiple linear grating reflection layer. Both this reflection layer and the anti-reflection layer are linear grating irradiations, and the radiations are in the same quadrant. By increasing the opportunity for the superposition of the radiations, the radiation light is enhanced and the light uniformity is improved. This is the sterilization space device configured as such. In the multiple linear grating GUV LED fluid sterilization device of the present invention, it includes one or more linear grating GUV LED lamp beads, and corrects the GUV LED sterilization light to 2D linear transmission so as to enhance the radiation intensity. In at least one embodiment, the linear grating GUV LED lamp beads of the present invention can be connected in series, in parallel with each other, or arranged in an array. Its DC power supply device is introduced by general power of DC24V or less or a battery to control the supply of power to the PCB board, and is used to light the linear grating GUV LED lamp beads or the air extractor. In the concave arc-shaped linear grating GUV LED lamp beads of the present invention, a viewing window pre-installed on the outer side of the quartz tube is provided, and the hollow quartz tube is joined to the columnar end of the concave arc surface of the arc-shaped cylindrical lens, and the horizontal axis of the sterilization space chamber is parallel to the horizontal axis of the arc-shaped cylindrical lens. Except that the joint at the curved surface end of the arc-shaped cylindrical lens is the outer wall of the transparent viewing window, the outer walls of other quartz tubes have an aluminum metal ultraviolet reflection surface coating or a vacuum-evaporated aluminum reflection layer, and the sterilization space chamber has openings at both end faces to allow fluid to flow through the sterilization space chamber, serving as a spatial device for multi-linear grating GUV LED fluid disinfection and sterilization treatment. The linear grating GUV LED lamp beads of the present invention are connected to a sterilization space chamber made of an aluminum metal material. The inner surface of the hollow aluminum tube wall is one of a continuous convex or continuous concave arc-shaped columnar mirror and has openings at both end faces. The hollow inner tube wall is one of circular, rectangular, and square, the diameter of its inner diameter or aperture is within 30 mm, and a hole is pre-installed on one side thereof to serve as a viewing window for installing the linear grating GUV LED lamp beads. The viewing window holes may be one or more. The linear grating GUV LED lamp beads irradiate radiation into the sterilization space chamber through these holes, irradiating from the outside to the inside to form a radioactive grating surface with a cross-section perpendicular to the columnar mirror. The phases of the reflected or anti-reflected radiation are different, but all are multi-perpendicular to the columnar cross-section and in the same cross-sectional quadrant, increasing the overlap rate of the radiation and making the radiation intensity stronger and more uniform, thus enabling a multi-linear grating GUV LED fluid sterilization space chamber. As in the above embodiments, inside the aluminum hollow tube, the same transparent quartz tube is combined as a viewing window for attaching linear grating GUV LED lamp beads. The linear grating GUV LED lamp beads irradiate radiation through this hole, enter the quartz tube, and enter the space chamber of the sterilizing quartz tube, irradiating from the outside to the inside to form a radioactive grating surface whose cross-section is perpendicular to the columnar mirror. The reflected or anti-reflected radiation is reflected by the continuous columnar mirror coated with aluminum on the outside and enters the sterilizing space again. Although the phases of the reflected light and the anti-reflected light are different, both are perpendicular to the columnar cross-section multiple times and are in the same cross-sectional quadrant, increasing the overlap rate of the radiation and making the radiation intensity stronger and more uniform. As the sterilizing space chamber of the water fluid, the inner diameter of the chamber is limited within 30 mm. Although GUV has high energy but low transmittance, ions such as calcium, magnesium, silicon, oxygen, and nitrogen always exist in water, which greatly affects the GUV transmittance. Therefore, a limit is set to ensure the sterilization rate. The linear grating GUV LED lamp bead device of the present invention includes a plurality of linear grating GUV LED lamp beads. The lamp beads 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 sterilizing space so as to increase the radiation intensity. In the linear grating GUV LED lamp beads of the present invention, the wavelength is between 234 nm and 313 nm. According to Einstein's photoelectric theorem, the dissolution of the DNA or RNA of germs is related to the absorption band of its light wave. The absorbed photons have an energy conversion of chemical action, which can dissolve and break the chemical bonds of the DNA or RNA. The germs lose their activity due to the cut DNA or RNA, which is called disinfection and sterilization. According to the publication of the International Commission on Illumination (CIE), its absorption peak is 265 nm, and its valley is 234 nm - 313 nm. The band of the linear grating ultraviolet sterilization of this patent is 234 nm - 313 nm, which is called GUV LED, including the wavelengths of some UVC and some UVB, modified by a cylindrical lens, and linearly modifies the emitted light based on the Maddox Rod transmission principle. Since its light source is not a single point, multiple point light sources form a plurality of linear parallel linear projections, which is called linear grating projection, and form the linear grating GUV LED lamp beads 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, it further includes an exhaust mechanism and a front edge filter installed in the system, which actively sucks in air and passes through the sterilization space chamber of multiple linear grating GUV LED lamp beads. The air first passes through the filter to remove particulate foreign matter, and then enters the hollow chamber of the sterilization space, is exposed to ultraviolet light for sterilization, and then the clean air enters one of a nose sleeve, a mask, a respirator, a nose cover, a face shield, a head cover or a connector, forming a positive pressure mask for people to use. In other embodiments, and the sterilization device of the present invention is installed at the air outlet of the protective cover wearer. The protective cover is made of an airtight polymer and is provided with an air or oxygen inlet to form a positive pressure inside the protective cover, discharging the used air from this air outlet. Before the waste gas leaves the protective cover, it must first pass through the multiple linear grating GUV LED fluid sterilization device to return the sterilized air to the environmental space, forming an environment without pollution and germs. The present invention also provides a linear grating GUV LED fluid sterilization space device. In at least one embodiment, the fluid sterilization space device is arranged or combined as a water solution fluid sterilizer, for example, with faucets, water dispensers, water outlets, drains, sewage treatment devices, waste liquid treatment devices, and liquid treatment devices for medical waste. 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 can be used as a disinfector, sterilizer, cleaner, or air-fluid treatment device that can be used as a sterilizer. The operation of the multiple linear grating GUV LED fluid sterilization space device of the present invention is as follows. 1. Start the DC power supply device: The power pack may be general power of DC 24V or less or a battery, and can send power to the control power PCB board through the power supply contact. 2. Linear grating GUV LED lamp beads: Light up the linear grating GUV LED lamp beads to emit ultraviolet radiation of 234 - 313 nm, and through the cylindrical lens, emit the radiation parallel to each other to form a linear grating surface. 3. Radiation viewing window device: The viewing window device is on the side of the sterilization space chamber, and may be a quartz viewing window through which GUV passes or a hole for pre-installed GUV LED radiation to enter. The radiation is irradiated from the outside to the inside and enters the sterilization space chamber vertically. 4. Sterilization space chamber: The device has openings at both ends, the inner surface is a cylindrical mirror, and a viewing window for radiation to enter is pre-installed on its side. The GUV radiation light performs multiple linear grating reflections and anti-reflections on the inner surface of the sterilization space chamber. The fluid to be treated enters the sterilization space chamber from one end in the flow direction for sterilization exposure treatment, and the sterilized fluid is discharged from the outlet end of the sterilization space chamber. 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 directions of the ultraviolet rays inside the sterilization space form linear grating surfaces parallel to each other and perpendicular to the column axis. The radiation is repeatedly reflected by the columns in the chamber and is all in the same quadrant. To increase the probability through the superposition of the radiation, the radiation intensity is increased, and the uniformity of the radiation is also better due to multiple superpositions. It should be noted that all the radiation paths are perpendicular to the columns of the chamber. By restricting the ultraviolet rays within the sterilization space chamber, it is possible to prevent the leakage of ultraviolet rays and prevent environmental pollution caused by secondary radiation. The technology of the present invention is used in sterilization treatment devices for faucets, water dispensers, water outlets, drainage outlets, sewage treatment devices, waste liquid treatment devices, and fluids such as the liquid of medical waste, or breathing air, oxygen, or medical waste gas. The main body of the sterilization space device of the present invention functions to allow fluid to pass through, and is also a space where GUV LED sterilization light is retained in the sterilization space to prevent ultraviolet rays from leaking and polluting the environment. Although GUV LED sterilization light can sterilize and has no drug resistance, it can also damage the human skin and eyes. Therefore, the best method when applying GUV LED sterilization light is to perform the sterilization operation inside the sterilization space device. However, for GUV LED sterilization light, it should be prevented from being exposed to the air and causing harm to the human body. For continuously flowing air and water that need to be treated, it is a feature of the present invention that the treatment time is short, the flow rate is large, and the leakage of GUV LED sterilization light can be controlled in an open space. In the sterilization space device of the present invention, the GUV LED sterilization light source is first corrected once by a cylindrical lens to make the light perpendicular to the arc-shaped cylindrical lens, forming a linear grating, and is emitted to the viewing window hole on the side of the fluid sterilization space chamber. The radiation is irradiated from the outside to the inside and enters the sterilization space chamber. Then, a second reflection-type columnar linear grating correction is performed on the GUV LED sterilization light to form multiple parallel linear grating surfaces of the GUV LED sterilization light inside the sterilization space chamber. Due to the reflection of the GUV LED sterilization light in the direction of the transverse columnar surface of the sterilization space chamber, the incident angle of reflection of each grating surface is different, so the direction of the anti-reflection grating surface also changes. However, the reflection direction of the light is always transverse to the columnar direction and parallel to each other, which is called the GUV LED multiple linear grating surface. The GUV LED sterilization light is reflected multiple times in the same quadrant, which can increase the overlap rate of the radiation, uniformize the radiation, and increase the radiation intensity. When the GUV LED sterilization light is reflected inside, the reflection angle of the reflected light changes many times with the different incident angles. There is GUV light in 360 degrees, and the virus bacteria hidden in the dust have no escape route, so that there are no virus bacteria that are not sterilized. This is the effect of the sterilization space device in the present invention. This invention is a multi-linear grating GUV LED fluid sterilization space device. Using its characteristics of air treatment, disinfection, and inactivation, the treated air is conveyed through a nose sleeve into a face shield, mask, and nose cover by an exhaust mechanism and a blower mechanism. Clean air enters to form a positive pressure around the mouth and nose, preventing viruses from entering the mouth and nose due to negative pressure. Therefore, positive pressure oxygen helps oxygen enter the lungs, and the high-concentration carbon dioxide and waste heat energy exhaled by the lungs can be quickly discharged outside the mask due to the positive pressure, protecting the health of the person wearing the mask and having a comfortable effect. Furthermore, the airtight face shield, mask, and nose cover that are not ventilated are collectively called a protective cover. At the exhaust outlet of the waste gas, the multi-linear grating GUV LED sterilization space device of this invention is installed to further treat the exhaust gas containing virus bacteria from the wearer, sterilize it first, and then discharge it to prevent infection to others. For example, it is worn by patients with diseases such as colds, tuberculosis, avian influenza, and novel coronavirus pneumonia. In the multi-linear grating GUV LED sterilization device of this invention, its water treatment and disinfection and sterilization characteristics are utilized and applied to the drinking water outlet to serve as a flowing water treatment device. Furthermore, it is connected to the device to increase the water treatment volume and can also be used for washing food ingredients and taking baths at home. Additionally, it can be installed at the drainage outlet of contaminated wastewater such as medical wastewater for disinfection and inactivation, for example, to reduce the virus bacteria contamination of the mouthwash water in a dentist's office.
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 space device of the present invention controls and processes the fluid sterilization operation in the sterilization space chamber, which includes the design of optical lamp beads with the gain intensity of linear grating radiation. Using the linear grating 2D sterilization light, the UV high-reflectivity material is irradiated from the outside to the inside, and the columnar linear grating reflection or anti-reflection radiation is utilized to coexist in the same quadrant region, increasing the opportunity of radiation superposition, enhancing the radiation dose in the sterilization space, and shortening the sterilization time. Since the radiation direction of the linear mirror device is controlled, it is not easy to leak from the sterilization space, is environmentally friendly, and there is no environmental problem of secondary pollution.

Embodiments for Carrying Out the Invention
[0007] Regarding the multiple linear grating ultraviolet germicidal (GUV) LED fluid sterilization space device according to the present invention, in order for those skilled in the art to fully understand the object, features, and effects of the present invention, appropriate embodiments are given below, and together with the attached drawings, the technical content of the present invention will be described in detail. FIG. 1A, FIG. 1B, FIG. 1C, and FIG. 1D show schematic cross-sectional views of the linear grating GUV LED lamp beads 10 installed in this embodiment. As shown in FIG. 1A, it includes a GUV LED die 101 packaged on a wire frame substrate 100 that emits sterilizing light which is ultraviolet radiation in the wavelength band of 234 nm to 313 nm, and an inner concave arc cylindrical lens 102 made of an ultraviolet-transmitting material installed on the packaged GUV LED die 101. Alternatively, as shown in FIG. 1B, in other embodiments, the GUV LED die 101 is similarly packaged on the wire frame substrate 100. However, what is packaged on the die 101 is a continuous inner concave arc cylindrical lens 202. Also, as shown in FIG. 1C, what is packaged on the GUV LED die 101 is an outer convex arc cylindrical lens 302 made of an ultraviolet-transmitting material. In addition, as shown in FIG. 1D, what is packaged on the GUV LED die 101 is a continuous outer convex arc cylindrical lens 402. The ultraviolet arc columnar transmitting materials of the arc cylindrical lenses 102, 202, 302, and 402 are one of quartz, sapphire, fluorinated polymer, polydimethylsiloxane (PDMS), polyimide (PI), etc. On the other hand, based on the principle of Maddox Rod transmitted light, the packaging of the arc cylindrical lenses 102, 202, 302, and 402 forms linear light that scatters on both sides perpendicular to the columns of the arc cylindrical lenses 102, 202, 302, and 402, restricts the GUV LED emission angle to linear 2D sterilizing light parallel to each other, extends outward to form a grating surface, irradiates many parallel light illumination surfaces as a linear grating surface like a grating, and the length of the irradiation distance is determined by the curvature of the arc cylindrical lenses 102, 202, 302, and 402. Combining with the wire frame substrate 100 and packaging the GUV LED die 101 results in the transmissive linear grating GUV LED lamp beads 10 according to the present invention. Figure 2 shows a schematic diagram of an embodiment of the linear grating GUV LED fluid sterilization space device 20 of the present invention.

There is a power supply contact 112 on the control power supply PCB board 107, which is connected as a power supply to a DC power supply or a battery 113 described later. The inner concave arc cylindrical lens 102 of the linear grating GUV LED 10 is installed on the outer wall side of the quartz tube 108, and an aluminum powder reflection layer 110 is coated on the entire outer wall surface of the quartz tube 108 except for the quartz viewing window 115 at the joint between the inner concave arc cylindrical lens 102 and the quartz tube 108, or aluminum metal is vacuum-deposited to form an inner concave columnar reflector for radiation. The radiation forms a linear grating surface parallel to the columnar cross-section by reflection of the columnar quartz tube 108, and is anti-reflected multiple times to increase 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 fluid is passed through as a sterilization treatment space in the middle, and there are openings at both ends thereof, and the fluid can flow into the sterilization space chamber 103 of the quartz tube 108 in the 109 direction. 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. Figures 3A, 3B, 3C, 3D, 3E, and 3F show schematic cross-sectional views of the fluid sterilization space device according to the present invention. As shown in Figure 3A, the linear grating GUV LED fluid sterilization space device 20 has a structure in which a sterilization space chamber is formed by plating high-reflective aluminum outside an inner cylindrical arc-shaped columnar mirror 1081 made of quartz. Alternatively, as shown in Figure 3B, a sterilization space chamber is formed using metal aluminum or tetrafluoroethylene, processed into an inner circle, and having a continuous convex columnar arc-shaped columnar mirror 1082. Alternatively, as shown in Figure 3C, a sterilization space chamber is formed using metal aluminum, processed into an inner circle, and having a continuous concave columnar arc-shaped columnar mirror 1083. Alternatively, as shown in Figure 3D, a sterilization space chamber is formed using metal aluminum or tetrafluoroethylene, processed into an inner square, and having a continuous outward convex columnar arc-shaped columnar mirror 1084.

The structural configuration of the linear grating GUV LED lamp beads 10 is attached through the GUV LED holes 116 or a pre-installed quartz viewing window 115. The diameter or width of the sterilization space chamber is within 30 mm, forming the linear grating GUV LED fluid sterilization space device 20. Also, Figure 4 shows a schematic diagram of an application example of the linear grating GUV LED fluid sterilization space device 20 of this embodiment.

An air filter 803 for filtering fine particles in the air is installed at the other end of the sterilization space chamber 103. The blower 802 actively sucks in air, the air flow is exposed by the linear grating GUV LED lamp beads 10, passes through the sterilization space chamber 103, undergoes air fluid sterilization treatment for sterilization, and the clean air after sterilization is sent to the vicinity of the wearer's nostrils through the nose sleeve 801 and is led out through the air outlet 808 to allow the wearer to inhale clean air, forming an active fluid sterilization space device. Also, the embodiments according to FIGS. 7 to 9 are substantially similar to the embodiment according to FIG. 6. As shown in FIG. 7, the clean air after sterilization is sent to the vicinity of the nostrils inside the face shield 804 through the nose sleeve 801 to form a positive pressure inside the face shield 804. As shown in FIG. 7, the clean air after sterilization is sent to the vicinity of the nostrils inside the mask 805 through the nose sleeve 801 to form a positive pressure inside the mask 805.

The treated clean air is sent into the face shield 804, the mask 805, the nose cover 806 to form a space with a positive pressure environment. During inhalation, oxygen can easily enter the lungs under positive pressure, without dizziness due to lack of oxygen in the blood. During exhalation, due to the positive pressure relationship, the exhaust gas diffuses easily, and carbon dioxide is also rapidly diffused and exhausted outside the mask. Furthermore, water vapor and hot air are sent out together to assist the person wearing the face shield 804, the mask 805, the nose cover 806. When inhaling again, the amount of oxygen increases, the amount of carbon dioxide decreases, and there is no damp heat or shortness of breath, and the oxygen content in the blood increases. Due to the positive pressure, it is difficult for the dirty air from the outside to enter the face shield 804, the mask 805, or the nose cover 806, which can protect the wearer from virus and bacteria infection and can be applied to the positive pressure safety face shield 804, the mask 805, or the nose cover 806 of the present invention.
