Description

Inspection and quarantine respiratory protection device for up-conversion material
Technical Field
The invention relates to a respiratory protection device, in particular to a quarantine respiratory protection device of an up-conversion material, which is used for exciting the up-conversion material to generate ultraviolet sterilization effect by light energy transmitted by a light transmission material.
Background
Respiratory protection devices, such as masks and breathing masks, are one of the essential items necessary for inspection and quarantine protection personnel, and are protection articles for people to prevent the harm of air pollution to body health. The up-conversion material, namely Anti-Stokes luminescent material, means that the material is excited by light with low energy and emits light with high energy, namely light with long wavelength and low frequency, and the material emits light with short wavelength and high frequency.
The mask sewn by adopting the multi-layer gauze can only filter out larger dust particles in the air, has poor protection effect on bacteria and viruses transmitted by spray and air, and can not meet the requirements of personnel protection when epidemic situations such as SARS, avian influenza, H1N1 influenza A, middle east respiratory syndrome and the like occur.
The mask made of the high-efficiency fiber filter material can play a good role in filtering and protecting tiny particles, bacteria and viruses. People are increasingly required for the mask, and the problem of disinfection of the mask and the air sterilization condition in the mask are more and more concerned when the filtering effect is pursued.
However, the existing mask generally does not have the effect of killing bacteria and viruses, and the filtering effect is poor after long-term use, and the problem of secondary pollution caused by microorganism breeding is easy. Although the mask can be treated by chemical, the treatment can only be carried out in a non-use state, and the mask in use cannot be disinfected in real time. The moist and warm environment of the mask is very suitable for bacteria and viruses to quickly breed and reproduce. There are also cases where the mask is irradiated with ultraviolet rays to sterilize and disinfect the mask rapidly, but the ultraviolet rays only act on the mask surface and cannot act on germs and viruses attached to the surface of the fiber material inside the filter material layer.
One common solution for surface disinfection and treatment of contaminants in public transportation and medical systems is to deposit a photocatalytic coating (PCC), i.e. a coating with photocatalytic oxidation properties on the surface to oxidize contaminants in the air and eliminate microorganisms. At present, a relatively reliable PCC is to use a photocatalytic material to generate an active oxygen coating, wherein the photocatalytic material can generate a catalytic reaction similar to photosynthesis under the irradiation of sunlight or fluorescent lamps, so that oxygen and water molecules in the air are excited to form hydroxyl free radicals and superoxide anion free radicals with extremely high oxidizing capacity. The free radicals with extremely strong oxidizing power can kill bacteria floating in the air and continuously degrade organic pollutants into water, carbon dioxide and the like, thereby achieving the purposes of purifying the environment and keeping the material clean and free from pollution. Titanium dioxide is a widely used photocatalytic material, and when anatase titanium dioxide is irradiated with ultraviolet light of a specific wavelength, its photocatalytic oxidation and antimicrobial function are activated. However, the intensity of ultraviolet light in the room is generally low, and an additional ultraviolet lamp must be installed to function as titanium dioxide, which clearly limits the application of titanium dioxide.
The ultraviolet sterilization technology is to use a specially designed ultraviolet generating device to generate UVC (200-280 nm) irradiation, and when a certain dose of UVC is irradiated to various bacteria, viruses, parasites, algae and other pathogens, the deoxyribonucleic acid or ribonucleic acid structure in cells is destroyed, replication and reproductive capacity are lost, and finally death is caused, so that the purposes of sterilization, disinfection and purification are achieved under the condition that no chemical medicine is used. From an environmental point of view, all ultraviolet lamps emit ultraviolet light by ionization of mercury vapor, energy level transitions. Metallic mercury is a toxic metal that is easily volatilized in air. In the production, sales, use and recycling of ultraviolet lamps, there is a large amount of mercury leakage, which can cause pollution to the surrounding environment. On the other hand, the ultraviolet sterilizing products which are used in the market at present are low-pressure mercury lamps which are unimodal ultraviolet light, the emission wavelength peak value of the ultraviolet sterilizing products is 253.7nm, the sterilizing effect is single, the sterilizing effect on various bacteria is poor, the medium-pressure mercury lamps with good sterilizing effect are high in power and low in photoelectric conversion efficiency, and the total sterilizing effect is also not ideal. The widely-seen alternative light source of the mercury lamp is a UV-LED, and the characteristics of no mercury, energy conservation and portability are receiving more and more attention. The UV-LED works well in a UVA (320-380 nm) wave band, but has a plurality of problems in a UVB (280-320 nm) wave band and a UVC wave band, particularly in the UVC wave band, when the wavelength is smaller than 280nm, the output power is only a few mW, and the service life is short. The Chinese patent with the application number of CN201410584398.8 discloses an LED ultraviolet sterilizing lamp, which adopts ultraviolet light with the wavelength of 250-270 nm emitted by a UVC semiconductor, and limits the application of the LED ultraviolet sterilizing lamp as an ultraviolet sterilizing light source.
In order to reduce the harm to human bodies and the environment, development of a mercury-free ultraviolet light source which has low cost, no pollution and high efficiency and can replace the traditional mercury-containing ultraviolet lamp is needed, and the mercury-free ultraviolet light source has important practical significance and research value in the sterilization and disinfection fields.

The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
Example 1
Fig. 1 is a schematic diagram of a quarantine respiratory protection device of an up-conversion material according to the present invention, and fig. 2 is an enlarged effect diagram of a light emitting filter material layer structure of the quarantine respiratory protection device of the up-conversion material according to the present invention.
As shown in fig. 1 and 2, the inspection and quarantine respiratory protection device of the up-conversion material comprises a respiratory protection device body 101, a light generating device 102 and a light emitting filter layer 103, wherein the light generating device 102 and the light emitting filter layer 103 are arranged on the respiratory protection device body 101. Wherein:
the luminescent filter layer 103 comprises filter fibers 201 and light conducting fibers 202. In another embodiment, the luminescent filter layer 103 may also include only the light conductive fibers 202. The light-transmitting fiber 202 has a function of filtering and adsorbing particles, liquid droplets, and the like in a fluid (e.g., air stream) by a filter material by van der waals force, electrostatic force, and the like.
The light-transmitting fiber 202 is coupled to the light-generating device 102, and when the light generated by the light-generating device 102 is transmitted in the light-transmitting fiber 202, the total reflection condition of the light transmission is destroyed due to bending, breakage, foreign matter, etc., the light continuously leaks from the surface of the light-transmitting fiber 202, and the light is introduced into the light-emitting filter layer 103. The filter fiber 201 and/or the light-conducting fiber 202 contains an up-conversion material 203, the light-conducting fiber 202 guides the light generated by the light generating device 102 to enter the light-emitting filter layer 103, the light entering the light-emitting filter layer 103 irradiates on the up-conversion material 203, the up-conversion material 203 generates ultraviolet rays, and the ultraviolet rays irradiate on the surfaces of the filter fiber 201 and/or the light-conducting fiber 202.
Here, the light-conducting fiber 202 is an optical fiber that is subjected to a resident polarization treatment. Preferably, the light guide fiber is a side-emitting light guide fiber. The optical fiber is convenient to manufacture and low in cost, the optical fiber can realize high-efficiency transmission of light, avoid strong absorption of the light, ensure the intensity of the light reaching the surface of the filter fiber 201 and ensure the disinfection and sterilization effect. The light guide fiber can conveniently achieve a very small diameter, and particles, liquid drops and the like in the fluid are filtered and adsorbed by means of the surface adsorption force. Particles, liquid drops and the like attached to the surface of the optical fiber change the total reflection condition of the surface of the optical fiber, light conducted inside the optical fiber overflows, the particles, the liquid drops and the like are irradiated, and the effect that the light rays are transmitted and conducted along with the distribution of the number of the particles and the liquid drops in the filtered and adsorbed fluid of the optical fiber is achieved.
Here, the up-conversion material 203 may be one of compounds doped with rare earth ions, including fluoride, oxide, sulfur-containing compound, oxyfluoride, halide, and the like; the up-conversion material 203 may be any combination of two, three or more compounds doped with rare earth ions, such as fluoride, oxide, sulfur-containing compound, oxyfluoride, and halide. In practical applications, the up-conversion material 203 is uniformly distributed on the surface of the filter fibers 201 and/or the light conductive fibers 202 in the form of fine particles and/or fibers and/or films. For example, naYF4 is currently the most efficient host material for up-conversion luminescence, such as nano-sized NaYF4: er (Er) 3+ ，Yb 3+ The method comprises the steps of carrying out a first treatment on the surface of the When ytterbium and erbium are doubly doped, er is used as an activator, and Yb is used as a sensitizer. The up-conversion material 203 has an emission spectrum range of 200 nm-280 nm and has strong disinfection and sterilization effects. The NaYF4 up-conversion material can be excited to generate ultraviolet light only under the condition of common illumination light, and a special ultraviolet lamp is not required to be installed, so that the NaYF4 up-conversion material has no additional installation cost and operation cost and has no worry about harm to people and livestock caused by ultraviolet light.
The up-conversion material 203, which is used as a converter, absorbs the irradiated light (i.e. is excited by low energy light) and emits ultraviolet light which can be sterilized and disinfected efficiently. The ultraviolet light generated by the ultraviolet light can kill microorganisms such as bacteria, viruses and the like trapped and attached on the whole luminous filter layer 103, so that the filter fibers 201 on each layer of the luminous filter layer 103 are disinfected and sterilized, the pathogen transmission and cross infection risks are reduced, secondary pollution is avoided, and the health level of a user is protected.
The inspection and quarantine respiratory protection device is particularly suitable for inspection and quarantine treatment personnel, medical epidemic prevention personnel and personnel working and living under high-dust and high-pollution environments. As only ordinary light illumination conditions are needed, the ultraviolet lamp is not needed to be arranged, and the ultraviolet sterilization and disinfection effects can be exerted. Therefore, no extra installation cost and operation cost are generated, and the worry that the ultraviolet light is generated by installing the ultraviolet light lamp and the health of people and livestock is endangered is avoided.
