Description

Method for preventing air harmful microorganism infection and gas shield device

Technical Field

A method and a gas shield apparatus for preventing the infection of air harmful microorganisms. Relates to a gas shield for preventing air pathogenic harmful microorganisms, in particular to a novel coronavirus, preventing the novel coronavirus from forming human-to-human transmission and infection through human respiratory tract, and providing people with a gas shield to wear.

Background

There are many pathogenic harmful microorganisms in the air, including various bacteria, various viruses, and in particular, the new coronaviruses that are currently occurring. The novel coronavirus has extremely strong infectivity, strong replication capacity, continuous adaptation to the change of a host in the replication process and continuous mutation, and rapid mutation speed. The novel coronaviruses belong to the family of the beta coronaviridae, and have a capsule membrane with a diameter of about 40-160 nanometers. The activity of the novel coronavirus has a great influence on the survival time, temperature and humidity and the surrounding environment. The activity has been significantly reduced after 2 hours in a dry environment and can remain viable on smooth surfaces for around 1 to 2 days. The smooth surface of the object can enable the virus envelope to generate a semi-sealing state, the strain is protected, and the activity and the survival time of the strain are prolonged. Strains rapidly lose activity when novel coronavirus strains are exposed to a rough surface in a ventilated and dry environment. The research shows that the survival time of the novel coronavirus reaches about 5 days under the condition of proper temperature and humidity. Since the novel coronaviruses are transmitted mainly through respiratory droplets and contact. Therefore, people need to wear masks to protect their health and safety with others. The mask is the most important protection means for preventing the infection of the novel coronavirus at present. However, the existing mask worn by people has the problems of unreasonable and unscientific methods and technical measures for protecting novel coronaviruses. The filter material that the gauze mask set up will bear the positive pressure gas filtration task that produces when breathing out the gas to the human body, and the negative pressure gas that produces when breathing in the gas again needs to be born, accomplishes the filtration task of the novel coronavirus of air, utilizes gauze mask protective air suspended particle technical measure, and the filter material of setting needs to bear the filtration task of accomplishing two kinds of different nature gases simultaneously. Particularly, when the human body exhales the gas with the water vapor, the water vapor discharged by the human body can form a water body on the surface of the polypropylene fiber because the polypropylene fiber woven melt-spun cloth filter material has no water absorption capacity. When the human body inhales from the mask, the generated negative pressure gas returns the water outside the mask filter material to the mask, so that the water on the mask filter material stays and gathers. The breathing rule of the human body in the mask aggravates the main reason that the water body forms on the filter material in a large quantity. When the polypropylene fiber woven melt-blown cloth filter material is formed in the water body, the filter material completely loses the capability and the function of protecting novel coronaviruses. At present, whether the mask is an N95 type mask worn by medical staff or a common medical mask, the technical principle of filtering and intercepting air particulate matters is the same, and the filtering material is a spray-melt cloth woven by polypropylene fibers. The weaving density aperture of the N95 type mask filter material special for medical staff is 300 nanometers; the weaving density aperture of the common medical mask filter material is 500 nanometers. For various bacteria and viruses with the aperture smaller than the textile density of the filtering material in the air, the medical N95 type mask and the common medical mask can only be under the gas condition by adopting the method: firstly, an irregular interweaved polypropylene fine fiber material formed in the melt-blown cloth is utilized to filter and intercept air fine particle suspended matters by utilizing a capturing method. Secondly, the Brownian motion principle is adopted; when fine suspended particles in the air enter the inner space of the irregular interweaved polypropylene fine fibers, the suspended particles are easy to be impacted by other gas molecules continuously, so that the motion tracks of the suspended particles generate irregular Brownian motion, and the suspended particles are captured and intercepted by the irregular interweaved polypropylene fine fibers. Thirdly, the electrostatic charge adsorption principle of polypropylene fibers is utilized. The polypropylene fine fiber spray fusion cloth belt has static charge, and extremely fine suspended particles in the air are adsorbed on the surface under the static charge action of the polypropylene fine fiber. When medical staff wears the N95 type mask and the common medical mask, the human body exhales the gas with moisture from the inside of the mask, and the filter material can be in a wet state in a short time. Particularly, medical workers need to wear the mask for a long time, a large amount of water body is formed on the filter material of the mask, and particularly after warm and moist air exhaled by a human body is condensed when meeting cold air in winter, a large amount of water body is formed on the filter material of the mask immediately. When the water body is formed in the spray melt cloth woven by the polypropylene fibers, the N95 type special mask worn by medical staff is provided with a plurality of layers of filter materials, or the common medical mask is provided with a plurality of layers of filter materials, so that the water body completely loses the capability and the function of protecting novel coronaviruses. The reason for this is that: the diameter of the novel coronavirus strain is 40-160 nanometers, the density aperture of the N95 type mask filter material special for medical staff is 300 nanometers, and the density aperture of the common medical mask filter material is 500 nanometers. When the two masks want to filter out the aperture that the diameter of suspended particles in air is smaller than the density of 300 nanometers and 500 nanometers of the filtering material, the spray melt cloth can only play the role of the polypropylene irregular interweaving fiber filtering material with the diameter of 1-5 micrometers in a dry environment under the condition of gas, thereby achieving the technical principle advantages of capturing, filtering and intercepting, electrostatic adsorption and Brownian movement of the suspended particles in air. When the polypropylene irregular interweaved fiber spray melt cloth surface is formed by water, the novel coronavirus on the filter material and the water form a mixed state, the water not only causes the surface of the filter material to generate lubrication effect, when the human body inhales in the mask to generate negative pressure gas, the diameter of the novel coronavirus is 40-160 nanometers, the diameter of the novel coronavirus is far smaller than the 300 nanometer aperture of the medical N95 model filter material, the diameter of the novel coronavirus is smaller than the aperture of the 500 nanometer common medical mask, and the novel coronavirus directly enters the mask from the pores of the filter material to form infection with the human body. When the mask filter material forms water, the water can form a whole by arranging a plurality of layers of polypropylene irregular interweaving fine fiber spray melt cloth pores, and the water can enable 300 nano pores of each layer of filter material of the N95 type mask and 500 nano pores of the common medical mask filter material to be communicated. Harmful microorganisms intercepted on the filter material, especially novel coronaviruses, form a mixed state with the water body on the filter material. When the human body inhales the gas in the mask, the novel coronavirus with the diameter of 40-160 nanometers is easy to infect the human body by the novel coronavirus in the mask from the pores of 300 nanometers and 500 nanometers of the filter material under the action of negative pressure gas. The water body has conductivity, and the water body can neutralize the static charge of the polypropylene fine fiber spray melt cloth. When the polypropylene fine fiber spray melt cloth filter material has water, the polypropylene fine fiber spray melt cloth completely loses the ability of electrostatic charge adsorption, capturing and intercepting filter air particulate matters, and the novel coronavirus cannot be fixed, and the set spray melt cloth filter material loses the protection effect on the novel coronavirus. The novel coronavirus produces brownian motion both under gaseous and liquid conditions. When the polypropylene fine fiber spray melt cloth is internally provided with water bodies, when the water bodies and the pores among the polypropylene irregular interweaved fibers are mutually communicated into a whole, the diameter of the novel coronavirus is only 40-160 nanometers, and when the water bodies on the filtering materials generate Brownian motion, the novel coronavirus strain easily enters the mask from the 300 nanometer pores of the special medical N95 type mask and the 500 nanometer pores of the common medical mask to cause infection to human bodies. In addition, when the surface of the polypropylene fiber filtering material with the diameter of 1-5 micrometers forms water, the smaller the diameter of the filtering material is, the smaller the density pores are, and the more the filtering material is blocked by the water. When the filter material is blocked by a water body, the air permeability of the filter material is difficult to provide the air quantity required by a human body. When the ventilation efficiency of the mask filter material is reduced due to the fact that water is formed in the mask filter material, not only is air sucked by a human body difficult, but also the flow speed of negative pressure air is increased on the pores of the filter material, and the filter material is difficult to fix harmful air microorganism particles, especially novel coronaviruses, so that the novel coronaviruses are easily sucked by the human body under the action of the increased air flow. Many people infected with the novel coronavirus are infected with the novel coronavirus when wearing a mask. In addition, when the human body exhales the gas with moisture in the mask, not only the required moisture is provided for bacteria and various viruses on the filter material, but also the proper temperature is provided for various bacteria and novel coronaviruses. So that bacteria and various viruses can get a warm bed on the filter material. Bacteria, especially novel coronaviruses, on the mask keep the viability on the filter material, and the survival time of the novel coronavirus strain is prolonged, so that the direct contact opportunity and the infection risk of the human body and the novel coronaviruses are increased. Because the mask can bring uncomfortable feeling to human body when being worn on the face, the mask is inevitably touched by hands, the whole surface of the mask is provided with the tasks of filtering bacteria and various viruses, and the surface of the mask is a place where gas is frequently exchanged. Therefore, bacteria and various viruses in the air can gather on the surface of the mask, and when hands contact bacteria and novel coronaviruses on the surface of the mask, the risk and the chance of being infected by the viruses are increased. When a human body inhales in the mask, under the action of negative pressure gas, the filter materials of the mask are mutually extruded, gas resistance formed on the filter materials is mutually overlapped, and when the filter materials are difficult to provide oxygen consumption required by the human body, the human body is difficult to breathe. Secondly, when the human body instinctively increases the forced inhalation, the negative pressure gas flow speed increased on the pores of the filter material enables various bacteria and novel coronaviruses with the diameter smaller than the density pore diameter of the filter material, the filter material cannot intercept and capture various bacteria and various viruses, particularly the novel coronaviruses, to be firmly controlled in the filter material, and various bacteria and novel coronaviruses can enter the inside of the mouth cover from the pores of the filter material, so that the risk and the chance of human body infection by the novel coronaviruses are increased.

The filtering technical method related to the arrangement of the filtering material of the medical N95 type mask and the common medical mask at present can only be limited to the air particulate matter filtering task of a human body when the human body inhales the air. When the human body inhales the gas in the mask, negative pressure gas is generated in the mask, and when the negative pressure gas acts on the surface of the filter material, the stress is mainly concentrated on the pores on the surface of the filter material, and the resistance of the whole surface of the filter material to the negative pressure gas is relatively small. When the human body exhales the gas in the mask, positive pressure gas is generated in the mask, and when the positive pressure gas acts on the whole surface of the filter material, the whole surface of the filter material has a resistance effect on the positive pressure gas, and the density of the filter material is difficult to smoothly discharge the gas exhaled by the human body. Therefore, when the human body exhales air in the mask, a part of air can only be discharged outwards from the edge of the mask, which is contacted with the face. If the coronavirus carrier is novel, a large amount of droplets with viruses are discharged outwards from gaps at the edge of the mask, so that an infectious source is formed, and mutual transmission and infection among people are caused. The mask is used for protecting novel coronavirus, and the two most important principles for protecting novel coronavirus are also seriously violated. Firstly, the gas exhaled by the human body in the mask provides proper temperature for pathogenic and harmful microorganisms on the filter material, including novel crown diseases and various bacteria; secondly, the gas exhaled by the human body in the mask is pathogenic and harmful microorganisms on the filter material, and the novel coronavirus and various bacteria provide a proper moist environment, so that the novel coronavirus and various bacteria have good survival conditions on the filter material of the mask, the novel coronavirus strain keeps survival activity on the filter material, and the survival time of the novel coronavirus strain on the mask is prolonged. Therefore, the N95 type professional mask worn by medical staff at present is also used for a common medical mask to adopt a method for filtering and intercepting pathogenic and harmful microorganisms of air particulate matters and adopting technical measures, and is difficult to be qualified for bearing the task of protecting novel coronaviruses. The arranged melt-blown cloth filter material can meet the requirements of the filter technical standard only under the gas condition, and can play the technical principle advantages of capturing, intercepting, electrostatic adsorption and Brownian motion filtration on the air pathogenic harmful microorganisms only under the dry condition.

A method and a gas shield apparatus (one) for preventing the transmission and infection of airborne harmful microorganisms are provided for preventing the transmission and infection of new coronaviruses between people through the respiratory tract: method for protecting air harmful microorganism from coronavirus and technical method and technical scheme and measure principle adopted by gas automatic conversion protective cover for solving technical problems

1. The technical method and the technical scheme measure principle adopted by the gas shield are as follows: in order to prevent harmful microorganisms in the air, particularly prevent novel coronaviruses from generating gaps from the contact position of the edge of the gas shield and the face to enter the respiratory tract to cause the infection problem of human bodies, and improve the wearing comfort of the gas shield, a soft sponge cylinder structure is adopted at the edge of the gas shield, protective fabrics are adopted outside the sponge cylinder, a certain space distance is formed between the gas shield and the face, a supporting framework is arranged inside the gas shield, according to the air harmful microorganisms, particularly aiming at the novel coronavirus protection requirement, sealing materials are adopted as the inner fabrics, and plush fabrics with good water absorbability and air permeability are arranged outside the inner fabrics. The gas protective cover fabric is provided with a medicine adding hole, the fabric is internally provided with a medicine liquid conveying pipe, and the prepared weak acid hypochlorous acid medicine liquid is injected into the protective cover fabric through a water outlet hole arranged on the medicine liquid conveying pipe.

2. The plush fabric is arranged on the surface of the gas shield, which relates to the technical method and the technical scheme principle, and the gas shield is a place for gas exchange and is also a place where air harmful microorganisms and novel coronaviruses are easy to gather. Particularly, the space is sealed in a multi-person gathering place, and the space is long-time gathered in classrooms, meeting rooms and movie theatres. Because the gas shield is worn at the face position, discomfort can be brought to the human body, and the gas shield is difficult to control and is not touched by hands. In order to timely inactivate and kill the novel coronaviruses falling on the gas shield fabric, the surface of the gas shield adopts the plush fabric, and the plush fabric can allow the novel coronaviruses to be ventilated on four sides and lose activity rapidly in a dry environment. The gas protective cover fabric adopts fabric with water absorption capacity, and aims to enable the fabric to inhale weak acid hypochlorous acid liquid medicine, enhance the capability of sterilizing novel coronaviruses on the surface of the gas protective cover, and prevent the possibility and risk of infecting the novel coronaviruses caused by touching the protective cover by hands.

When various bacteria and various viruses, especially novel coronaviruses fall on the liquid medicine of the plush fabric, the bacteria and strains can be killed by the liquid medicine on four sides, and hypochlorous acid has strong sterilizing capability on the novel coronaviruses through strong oxidizing property. When the protective cover fabric is required to be added with liquid medicine, a prepared liquid medicine bottle is permeated into the protective cover fabric through the liquid medicine delivery pipe water outlet.

3. The technical method and the technical scheme measure principle adopted by the gas shield are as follows: in order to thoroughly change the prior mask filter material, the filter material is used for protecting the novel coronavirus technical measures and is also used for carrying out the filtering task of the human body exhaust gas. In order to solve the serious shortages in the technical method, the invention arranges an automatic gas conversion device in the gas filtering channel according to the breathing rule and the characteristics of the human body, and automatically separates the inhaled gas and the exhaled gas of the human body in the gas protective cover. The automatic gas switching device is characterized in that a gas isolation plate is arranged in a gas filtering channel, a vent hole is formed in the gas isolation plate, a raised step is formed in the edge of the vent hole, a gas isolation plate with the size corresponding to that of the vent hole step is assembled on the raised step of the vent hole, the gas isolation plate adopts a thin film sheet body, the gas isolation plates are mutually connected through a net structure, the net sheets are gas isolation plates, and the net holes are gas channels. When the gas separation sheet is matched with the step of the vent hole bulge, the gas separation sheet can form tight fit and can be quickly separated from the step of the vent hole bulge. The upper edge of the vent hole adopts a raised step setting technology, so that the contact area between the gas isolation sheet and the gas vent hole is reduced to the greatest extent, the gas isolation sheet can be quickly separated and closed from the vent hole on the isolation plate under the weak air flow effect, and the gas isolation sheet is connected into a net structure for achieving the purposes of sensitive action and uniform stroke. When the human body breathes in gas in the gas shield to generate negative pressure gas, the negative pressure gas enters the gas shield from the air inlet filtering channel, and when the human body exhales out positive pressure gas in the gas shield, the positive pressure gas is discharged from the air outlet filtering channel.

4. The technical method and the technical scheme measure principle of the arrangement of the filter material of the air inlet filter channel are as follows: the filter material arranged in the air inlet filter passage is required to meet the capability of filtering and intercepting air harmful microorganisms and novel coronaviruses. Secondly, the filter material must have a certain ventilation efficiency to provide the oxygen amount required by the human body. Thus, the filter material disposed within the filter channels cannot be designed at a density that is currently found to be 20 nanometers in minimum virus diameter or 40-160 nanometers in novel coronavirus diameter. In order to solve the contradiction between the density and the air permeability of the filter material, the filter materials in each layer of filter channels adopt the technical measure of arranging the isolation net. When the measures of the isolation net are arranged among the layers of filter materials in the filter channel, the number of layers of the filter materials in the filter channel can be increased on the premise of ensuring the ventilation efficiency of the filter channel, so that the effects of improving the filter capability of the filter channel for filtering, intercepting and capturing micro suspended harmful microorganisms in air and particularly achieving ideal effects on the standard capability of the novel coronavirus filtering and intercepting technology are achieved. The technical measures of arranging the isolation net between the filter materials are adopted in the filter channel, so that the difficult problem that the density of the filter materials is larger than the diameter of the novel coronavirus is solved. The filter material arranged in the air inlet filter passage adopts the technical principle of the current mature spray melt cloth textile filter material. In order to enhance the filtering capability of the polypropylene irregular interweaved fiber woven spray-melt cloth, the irregular interweaved fiber spray-melt cloth which is formed by polypropylene fibers with the diameter of 1 micrometer and the weaving density of 300 nanometers is utilized, the polypropylene fibers with the diameter of 1 micrometer are reused on the surface of the spray-melt cloth, and a layer of compact plush filtering layer is woven on the surface of the spray-melt cloth again. The plush spray melt cloth reduces the flow speed of the gas in the filtering channel, increases the catching and intercepting capacity of the filtering material and solves the ventilation capacity of the filtering material. In order to ensure that the arranged plush spray melt-spun cloth filter material achieves the best protection effect of novel coronavirus, and the plush spray melt-spun cloth filter material can meet the ventilation efficiency requirement for providing human body gas, the number of layers and the technical standard of the filter material are arranged in an air inlet filter channel, and the polypropylene irregular interweaved fiber woven plush spray melt-spun cloth filter material arranged in the filter channel is doubled in the filtering technical standard and the filtering capability on the basis of the filtering capability of the current medical N95 mask. When the filter material arranged in the filter passage has double filter technical standard capability than that of a medical N95 type mask, viruses with the diameter of minimum 20 nanometers can be found in the air at first to be intercepted and filtered to achieve an ideal effect, and particularly, the optimal ideal effect for protecting novel coronaviruses is achieved. The technical measures of the isolation net are arranged between the layers of filter materials, so that a certain space distance is generated between the layers of filter materials, the phenomenon that negative pressure gas causes the layers of filter materials to be extruded mutually is prevented, and the problem that gas resistance is superposed mutually between the layers of filter materials is solved. The filter material layers adopt the separation net technology, so that the air permeability of the filter channel is improved, and the oxygen requirement required by human body is met. At present, a medical N95 type mouth of a melt-blown cloth woven by polypropylene fibers with the diameter of 1 micrometer is adopted, and the effective rate of filtering air suspended particulate matters is 95 percent. The plush spray melt cloth filter material arranged in the air inlet filter passage has the filtering capability which is twice more than the current medical N95 mask filter technical standard, and the technical capability and the technical standard of intercepting and capturing the novel coronavirus of the filter material arranged in the air inlet filter passage reach 99.99 percent. The air automatic conversion device is characterized in that an air automatic conversion device is arranged in a filtering channel, the inhaled air and the exhaled air of a human body in an air protective cover are split to automatically form unidirectional circulation, so that the plush-spraying fusible cloth filtering material arranged in the air inlet filtering channel can consistently filter, intercept, capture, electrostatically adsorb and utilize the Brownian motion principle to filter, intercept, capture and electrostatically adsorb air harmful microorganisms, and fully play the standard principle of the filtering technology of the plush-spraying fusible cloth filtering material to complete the filtering task of the air harmful microorganisms under the condition that the air is kept stable. Therefore, the technical standard of the plush spray melt-spun cloth filter material arranged in the air inlet filter passage is not changed in the wearing process of people. The plush spray melt-spun cloth filter material arranged in the air inlet filter passage works under the air condition consistently, and fully plays the technical advantage principle role of the polypropylene irregular interweaved fiber plush spray melt-spun cloth. A layer of compact plush is woven again on the surface of the spray melt cloth, the charging capacity of polypropylene fibers is enhanced, the capacity of the polypropylene fibers for adsorbing air suspended particles by static charge is increased, and the three-dimensional space capacity of the filter material for adsorbing, capturing and intercepting air fine suspended particles is increased by the arrangement technology of the plush layer. When the air tiny suspended particles and the novel coronavirus generate Brownian motion under the gas condition in the polypropylene irregular interweaved fiber plush melt-spun cloth material, the tiny suspended particles are easy to be impacted by gas molecules, and the novel coronavirus suspended particles are adsorbed on the surface of the fine fiber plush by the filter material to fix the fine fiber plush when the polypropylene irregular interweaved fiber plush melt-spun cloth material does irregular track Brownian motion. When a human body continuously inhales gas in the gas shield, the novel coronavirus fixed on the plush spray melt-cloth filter material is always in a ventilated and dry gas environment, and the novel coronavirus strain can quickly lose viability to achieve the purpose of killing.

5. The technical method and the technical scheme measure principle adopted by the filter material arranged in the exhaust filter channel are as follows: when the human body exhales positive pressure gas in the gas shield, the whole surface of the filter material arranged in the exhaust filter channel has resistance action on the positive pressure gas. In order to solve the problem that the whole surface of the filter material generates blocking gas circulation to positive pressure gas when a human body exhausts the gas and the problem that the filter material has water when the human body exhales the gas, the filter material is a fiber cotton filter material with good water absorption capacity and good air permeability. When the fiber cotton filter material sucks in the moisture and gas discharged by the human body, the water body on the filter material has certain viscosity, and the adverse factors of the water body discharged by the human body are converted into the capability of increasing the microorganism of the filter material for adhering harmful gas. In order to improve the capability of the exhaust filtering material to filter, intercept and capture harmful microorganisms and novel coronaviruses discharged by human bodies. The filter channel adopts the technical scheme of arranging the isolation net, the isolation net is arranged between the layers of filter materials, and through arranging the isolation between the layers of filter materials, the filter materials of the layers are prevented from being mutually extruded under the action of positive pressure gas, and the phenomenon of mutual superposition of gas resistance is prevented. The number of layers of the filtering material is increased in the filtering channel to filter and intercept harmful microorganisms which are discharged from human bodies through respiratory tracts, and the novel coronavirus improves the filtering technical standard and the filtering capacity of the filtering channel to meet ideal requirements. The thickness, the density and the layer number of the filter materials are set in the laboratory in advance, and after the comprehensive test is carried out on the suspended particulate matters in the filtered air, the technical standard that the thickness and the layer number of the filter materials are required to be additionally arranged in the filter channel and are determined is determined according to the result of the comprehensive test, so that the task of blocking and filtering the novel coronavirus is achieved.

A method for preventing the infection of air harmful microorganisms and a gas shield device (one) are provided for preventing the mutual transmission and infection of new coronaviruses between people through the respiratory tract: air harmful microorganism new coronavirus protection method and working principle related to gas automatic conversion protection

1. When the gas shield is needed to be worn, under the action of the supporting framework, a certain space distance is formed between the gas shield and the face, the soft sponge cylinder is arranged at the edge of the gas shield and can form sealing connection with the face, bacteria and various viruses without filtration are prevented from entering and exiting from the edge of the gas shield, and particularly, novel coronaviruses are prevented from being transmitted and infected mutually. The plush fabric arranged on the surface of the gas shield can make the novel coronavirus rapidly lose activity and viability in four sides ventilated in a dry environment. The gas shield area is a gas exchange place, is a place where air harmful microorganisms are easy to gather, is also a place where hands are easy to touch, and in order to avoid the risk that the hands touch the gas shield and are infected by the novel coronavirus, the novel coronavirus strain is enabled to be rapidly inactive on the surface of the gas shield, and finally the aim of eliminating the novel coronavirus strain is achieved. When the novel coronavirus falls into the risk of being infected on the surface of the gas shield in a long-time multi-complex gathering place of people, the weak acid hypochlorous acid liquid medicine is injected into the gas shield liquid medicine delivery pipe through the medicine feeding port arranged on the surface material of the shield, so that the liquid medicine is immersed into the plush fabric, the fallen bacteria and novel coronavirus strains are killed in time, the weak acid hypochlorous acid liquid medicine destroys the bacterial and novel coronavirus envelopes, and meanwhile, the novel coronavirus can directly enter the bacteria and novel coronavirus and react with nucleic acid proteins of microorganisms without electric charge and is inactivated rapidly. Low concentration and high activity of weak acid hypochlorous acid. The sterilization rate of 99.999 percent reaches 80 times of that of chlorine-containing products, and has special effect on killing novel coronavirus strains.

The utility model provides an intake filtering passageway and gaseous automatic switching device relates to theory of operation: when the human body inhales the gas in the gas shield, negative pressure gas is generated in the gas shield, and the negative pressure gas enables the gas separation sheet and the vent hole protruding steps arranged in the exhaust filtering channel to form a mutually-extruded state, and the separation sheet and the vent hole are tightly matched. When a human body inhales in the gas shield, various bacteria and various viruses, particularly novel coronaviruses, contained in the air harmful microorganisms cannot enter from the exhaust filtering channel device. When negative pressure gas is generated in the gas shield, under the adsorption of the negative pressure gas, the gas isolation sheet arranged in the air inlet filtering channel device is separated from the raised steps of the vent holes, and outside air smoothly enters the gas shield from the air inlet filtering channel to provide oxygen required by a human body.

3. The working principle that the filter material of the air inlet filter channel relates to: when the human body inhales gas in the gas shield, external air enters from the air inlet filtering channel, and when the air has various bacteria, various viruses, especially novel coronavirus strains: firstly, a method for intercepting and capturing the novel coronavirus and air harmful suspended particles by utilizing a polypropylene irregular interweaved fiber plush spray melt-cloth filter material is adopted to filter and intercept the novel coronavirus and air harmful suspended particles. Secondly, the electrostatic charge adsorption principle generated by the random interweaved fiber fleece melt-blown cloth of polypropylene is utilized to adsorb air harmful particulate matters, especially novel coronavirus strains, and the electrostatic charge adsorption principle generated by polypropylene fibers is utilized to adsorb air fine suspended matters, especially novel coronaviruses, in the filter material. Thirdly, when harmful microorganisms in the air, especially novel coronaviruses, generate irregular motion Brownian motion in the pores of the polypropylene irregular interweaved fiber fleece-blown melt, the air tiny suspended particles, including various bacteria and novel coronaviruses are easy to be impacted by gas molecules, and the tiny suspended particles in the air are adsorbed on the surface of the fine fibers under the irregular motion track to fix the tiny suspended particles. At present, the polypropylene irregular interweaved fiber melt-blown cloth used for weaving the medical N95 type mask is set to have the density of 300 nanometers, and the design standard effective rate of filtering, intercepting and capturing air particulate matters is 95 percent. In order to improve the capability of protecting against novel coronavirus infection, the polypropylene irregular interweaved fiber plush spray melt-cloth filter material arranged in the air inlet filter channel is provided with a double polypropylene irregular interweaved fiber plush spray melt-cloth filter layer in the filter channel on the basis of the filtering capability of the medical N95 mask, and the capability of filtering air harmful microorganisms and protecting against novel coronaviruses is remarkably improved. Therefore, the set filtering material has a reliable scientific basis for protecting the novel coronavirus capability, and the novel coronavirus capability and efficiency are prevented from reaching a reliable optimal ideal state.

4. When air harmful microorganisms and novel coronaviruses are intercepted and captured on the filter material by the polypropylene irregular interweaved fiber plush melt-blown cloth in the air inlet filter channel, the filter material arranged in the air inlet filter channel is always in a ventilated dry environment state under the continuous action of inhaled air of a human body to complete the filtration interception task, so that the air harmful microorganisms and novel coronaviruses are quickly inactivated in the dry and ventilated environment. Because the technical scheme of the isolation net is adopted among the layers of filter materials of the filter channel, on the premise of meeting the ventilation requirement of the filter materials, the filter channel achieves the ideal and optimal effect of filtering, intercepting and capturing air harmful microorganisms, in particular to the novel coronavirus capability by additionally arranging a plurality of layers of polypropylene irregularly interweaved fiber plush melt-blown cloth. Because the gas shield adopts the gas automatic switching device, the gas automatic switching device plays a role of a one-way valve in the gas shield. The gas inhaled by the human body and the gas exhaled by the human body form automatic separation unidirectional circulation in the gas shield. The filter material arranged in the air inlet filter channel can consistently complete the filtering task in the state of the air strip, and the ventilation efficiency of the filter material arranged in the filter channel and the set technical standard capability of filtering air harmful microorganisms can not be changed due to wearing and use of people. The gas inhaled by the human body in the gas shield and the gas exhausted are split, so that convenience is provided for human body respiration, meanwhile, the polypropylene irregular interweaved fiber plush spray melt cloth is provided with the functions of filtering, intercepting, capturing, electrostatic adsorption, capturing and intercepting by utilizing the Brownian motion generated by suspended particles under the gas condition, and the technical principle advantages of the filtering material are fully exerted. The automatic gas conversion device arranged in the filtering channel realizes the unidirectional flow automatic conversion of gas between the gas exhaled by the human body and the inhaled gas in the gas protective cover, and plays a key role in fully playing the technical principle advantages of filtering, intercepting and capturing air suspended matter particles of the plush spray fusible cloth.

5. The working principle related to the exhaust gas filtering channel and the gas automatic conversion device is as follows: when the human body needs to exhale in the gas shield, positive pressure gas is generated in the gas shield, and under the pushing of the positive pressure gas, the gas separation sheet arranged on the air inlet filter channel and the raised step on the vent hole form close fit, so that the positive pressure gas exhaled by the human body cannot be exhausted from the air inlet filter channel device. When the positive pressure gas exhaled by the human body enters the exhaust filtering channel device, the gas separation sheet arranged on the gas separation plate in the exhaust filtering channel is separated from the convex table, and the positive pressure gas exhaled by the human body is filtered by the filtering material arranged in the exhaust filtering channel and then is exhausted outwards. Various bacteria, various viruses, and particularly novel coronaviruses in the outside air cannot enter the exhaust gas filtering passage under positive pressure gas. In order to prevent air from entering the gas shield from the exhaust filtering channel, two automatic gas switching devices are arranged at the gas inlet end and the gas outlet end of the exhaust filtering channel, so that the reliability of unidirectional circulation of positive pressure gas and negative pressure gas in the gas shield is enhanced.

6. The technical working principle adopted by the filtering material of the exhaust gas filtering channel is as follows: when the human body exhales positive pressure gas in the gas shield, as the fiber cotton filter material with good air permeability and strong water absorption capacity is selected in the filter channel, the filter material not only smoothly discharges the positive pressure gas exhaled by the human body, but also generates adhesiveness in the filter material after the water gas is exhaled by the human body and is absorbed by the fiber cotton filter material, and the water absorption fiber cotton filter material not only solves the problem of water vapor discharged by the human body. And the water vapor is adhered to the filter material, so that the capability of the filter material for capturing and intercepting filtered harmful microorganisms is improved, and the water vapor discharged from the respiratory tract of a human body is converted into filtered air harmful microorganism coronavirus after being inhaled by the filter material, thereby creating favorable conditions. The technical measures of the isolation net are mutually arranged between the layers of filter materials, so that the filter materials are prevented from being mutually extruded under the action of gas pressure, the problem of mutual superposition of gas resistance between the filter materials is prevented, and after the fiber cotton filter materials are sucked into human body moisture, the air permeability of the filter materials is ensured, and meanwhile, the filter efficiency and the filter capacity are increased. The fiber cotton water-absorbing filter material has good air permeability, and the water-absorbing fiber cotton is an environment-friendly functional water-absorbing material which is air-permeable, flexible, non-combustion-supporting, nontoxic and non-irritating, has numerous pores among high-density fibers, and has water-absorbing capacity while guaranteeing air permeability. The filter material arranged in the exhaust filter channel always exhales positive pressure gas from a human body, under the continuous action of the positive pressure gas, the water vapor on the filter material only flows in one direction and cannot turn back again to generate a detention phenomenon, and the discharged water vapor can be continuously discharged outwards from the filter material under the action of the air flow generated by the positive pressure gas exhaled by the human body every time, so that the detention aggregation phenomenon of the water vapor on the filter material is avoided, and the ventilation capability of the exhaust filter channel is prevented from being influenced. The filter material disposed in the exhaust gas filter passage is set according to the test result by the simulation test in advance. Therefore, the efficiency of intercepting, filtering and capturing harmful microorganisms exhaled by a human body by the filter material arranged in the exhaust filtering channel meets the ideal standard requirement.

7. The working principle related to the technology of arranging an isolation net is adopted among the filter materials: by arranging the technical scheme of the isolation net between the air inlet filter channel and the air outlet filter channel, the contradiction problem generated between the density and the ventilation efficiency of the filter material is effectively solved. The problem of the mutual stack of air resistance that produces between each layer filter material has been prevented, under the prerequisite of guaranteeing filter material ventilation efficiency, utilizes to increase filter material layer number and thickness in the filtration passageway, has effectively solved the density (aperture) that filter material set up and is greater than the less not enough problem of air harmful particulate matter diameter. Through setting up the barrier net technique between each layer filter material, the barrier net has taken sufficient gas space in the gas passageway, and when gas motion to gas barrier net region, the velocity of flow of gas has formed a buffer zone in the barrier net region, and when gas motion speed suddenly reduced in the barrier net region, various thin, various viruses in the air have produced irregular motion under different air current collisions, and air suspended particle can suddenly change the motion track, and the barrier net region provides filter material capture interception filtration tiny suspended particle chance. The technical scheme that the isolation net is arranged between the filter materials of the filter channels is adopted, and the technical method provided by increasing the number of layers of the filter materials in the filter channels is utilized, so that the capability and the efficiency of the filter materials for intercepting and capturing air harmful microorganisms and novel coronaviruses are improved, and the capability of filtering the air harmful microorganisms and the novel coronaviruses reaches 99.0% of the technical standard capability.

When the strain of the novel coronavirus falls on the dried plush fabric with good air permeability, the novel coronavirus is ventilated on four sides of the plush fabric, and the strain can be quickly deactivated to achieve the purpose of gradually killing the strain, so that the risk and the opportunity of infection are reduced. Because the gas shield is arranged at the face position, discomfort can be brought to the human body, and the gas shield is difficult to control and is not touched by hands.

When the protective cover fabric needs to be added with liquid medicine, a liquid medicine bottle prepared in advance is injected into the liquid medicine conveying pipe through the medicine adding hole to permeate into the protective cover fabric. When the air inlet filter channel protective device and the air outlet filter channel filter protective device are arranged on the gas shield, the air inlet filter channel protective device and the air outlet filter channel filter protective device are taken off from the gas shield at any time for replacement after the effective working time is completed.

2. The technical method and the technical scheme measure principle adopted for solving the technical problems of the ultraviolet radiation method of the air inlet filtering channel are as follows: in order to better kill and block the novel coronavirus with the air suspended matter diameter smaller than the density of the filtering material, the technical advantage of stronger killing ability of ultraviolet rays on suspended particles with smaller diameters in the air is utilized, and the ultraviolet rays have strong killing ability particularly on the novel coronavirus. An ultraviolet radiation lamp is arranged at the gas inlet end of the air inlet filtering channel.

Ultraviolet rays have the capability of effectively killing harmful microorganisms, and particularly the ultraviolet rays have stronger killing power on microorganisms with smaller diameters in the air. The ultraviolet rays can reach the disinfection efficiency of 99-99.9 in one to ten seconds. The novel coronavirus is extremely insensitive to ultraviolet rays, has extremely strong killing power to the novel coronavirus according to the ultraviolet rays, adopts 1.5X7X7 (CM) in an ultraviolet box body arranged in an air inlet filter channel, adopts an ultraviolet lamp with 1 watt power according to the effective intensity of ultraviolet radiation of 70uW/CM according to the current mature experience of 1 square meter, has the volume of only 1.5 CM, 7 CM wide and 7 CM long according to the ultraviolet box body arranged in the air inlet filter channel, and also considers the adverse factors of the ultraviolet rays in the box body facing the gas flowing condition, in order to increase the killing power of the ultraviolet rays to the novel coronavirus, the lamp arranged in the ultraviolet box body adopts 0.05W (watt) power, has a radiation capacity which is several times higher than that of the ultraviolet rays under normal conditions, and the power supply of the ultraviolet rays is provided by a portable charging energy storage battery to provide 36 volt-ampere safety power for the ultraviolet rays.

3. The technical method and the technical scheme measure principle of the filtering protection and ultraviolet radiation combined protection of the air inlet filtering channel are as follows: because medical staff needs to wear the mask for a long time, the breathing of the medical staff is not difficult. The method is characterized in that the air inlet filtering channel adopts a combined protection method of ultraviolet radiation and a filtering material, so that the air harmful microorganisms are protected, and the protection capability on the novel coronaviruses is particularly enhanced. The ultraviolet rays are utilized to form the rapid killing capability and effect on air harmful microorganisms, and particularly the stronger the ultraviolet rays have to the microorganisms with smaller diameters, so that the defect that the aperture of the filter material is larger than that of the novel coronavirus and smaller than that of the filter material is effectively overcome, and the adverse factors of air flow are also effectively overcome. When ultraviolet rays kill harmful microorganisms in the air, especially against the novel coronavirus radiation, the harmful microorganisms are injured, disabled or killed, and the harmful microorganisms are intercepted, filtered and captured by the filter material, so that the aim of rapid killing on the filter material is achieved.

The technical measures of the isolation net are arranged between the layers of the filter materials, so that the technical measures of the multi-layer filter materials are additionally arranged in the gas filter channel, and the air suspended particulate matters are filtered, and especially the novel coronavirus achieves the ideal effect. The number of layers of the filter material is increased by the technical measure of arranging the isolation net in the air inlet filter channel, so that the defect that the density (pore diameter) of the filter material is larger than the diameter of the novel coronavirus is effectively overcome. The method for sterilizing the novel coronavirus by using ultraviolet radiation effectively compensates the adverse factors of the novel coronavirus and the gas flow. The ultraviolet rays have strong radiation disinfection capability on novel coronaviruses, and do not generate resistance to air, so that medical staff wear the mask for a long time, and the difficulty caused by breathing is relieved.

When the human body inhales the gas shield, air outside the gas shield, various bacteria and various viruses, particularly novel coronaviruses, cannot enter from the exhaust filtering channel device. When negative positive pressure gas enters the automatic gas conversion device of the gas inlet filtering channel, the vent hole protruding steps arranged on the gas isolation plate are separated from the isolation sheets, negative pressure gas formed by human body inhaling in the gas protection cover is filtered by the filtering material arranged in the gas inlet filtering channel, and oxygen required by human body is provided after the air is filtered.

When the human body exhales, air enters the ultraviolet box body from the inlet end, various harmful microorganisms including various bacteria, various viruses and especially novel coronavirus strains exist in the air, and the ultraviolet box body is subjected to three-dimensional radiation and back radiation of which the angles are 360 degrees and two mutually symmetrical 180 degrees from the box body, and the ultraviolet light is utilized to effectively kill harmful microorganisms, especially various bacteria and various viruses with small diameters in air suspension, especially novel coronaviruses, and the ultraviolet light achieves the effects of quick inactivation, disability and death after the radiation is killed, especially the novel coronaviruses with strong infectivity lose survival and killing effects. The method of ultraviolet rays for rapidly radiating air harmful microorganisms and novel coronaviruses effectively makes up the adverse factors of suspended particulate matters and gas flow of the filtering channel, and simultaneously makes up the defect that the density of the filtering material is smaller than the diameter of viruses. The rapid ultraviolet radiation method is arranged in the air inlet filtering channel, so that the guarantee is provided for medical workers in infectious departments and heating clinics, and the mental pressure and burden of the medical workers are reduced. In order to prevent aero-pathogenic harmful microorganisms, it is more necessary to strengthen personal protection for medical staff in infectious departments. When harmful microorganisms in air, especially novel coronaviruses, are killed by ultraviolet radiation, the filter material of the plush spray melt cloth is used to fix the tiny air particles and the novel coronaviruses on the surface of the plush spray melt cloth by utilizing the static charge adsorption technical principle generated by the polypropylene irregular interweaved fiber plush spray melt cloth and the Brownian motion principle, wherein the harmful microorganisms which are hurt, disabled or not irradiated, including various bacteria and various viruses, especially the novel coronaviruses, are arranged. As the filtering material filtering technical standard arranged in the air inlet filtering channel is improved by two times compared with the existing N95 special medical mask.

The following is a detailed description of a specific embodiment of a gas shield device and the working principle related to the method for preventing the infection of air harmful microorganisms and the gas shield device with reference to fig. 1 of the specification:

in fig. 1: when people wear the gas shield on the face, the sponge cylinder sealing strip (1) arranged at the edge of the gas shield is in sealing connection with the nose and the mouth; when a human body inhales in the gas shield, the gas shield generates negative pressure gas, and under the action of the negative pressure gas, the gas isolation sheet arranged in the exhaust filtering channel (2) is tightly matched with the vent holes, so that air cannot enter from the exhaust filtering channel (2); under the action of negative pressure gas, the gas separation plate arranged on the air inlet filter channel (3) is separated from the vent hole, and air smoothly enters the gas protection cover from the air inlet filter channel (3) to complete the gas filtering task, so that oxygen required by a human body is provided. When the human body exhales, positive pressure gas is generated in the gas shield, the positive pressure gas enables the gas separation sheet arranged in the gas inlet filtering channel (3) to form close fit with the vent hole, and the positive pressure gas cannot pass through the gas inlet filtering channel (3). Positive pressure gas separates a gas separation sheet arranged in the exhaust filtering channel (2) from an exhaust hole, gas exhaled by a human body is smoothly exhausted from the exhaust filtering channel (2), and the arranged air inlet filtering channel (3) completes the protection task of inhaling the gas by the human body; the exhaust filtering channel (2) completes the filtering task of the gas exhaled by the human body.

The following is a detailed description of a specific embodiment of a gas barrier sheet and the working principle related to a method for preventing the infection of air harmful microorganisms and a gas shield device with reference to fig. 2 of the specification:

in fig. 2: the gas separation sheet (3) is matched with the vent hole bulge step on the gas separation plate, and when the gas separation sheet (3) is separated from the vent hole, the gas of the filtering channel passes through the gas channel (2); when the gas separation sheet (3) and the vent hole form close fit, the filtering channel forms a closed state, and the gas separation sheet (3) and the gas channel (2) are mutually connected into a gas separation net sheet (1) structure by using the connecting strip (4).

The following is a detailed description of the specific embodiments and working principles of the gas filtering channel and the gas automatic switching device related to the method and the gas protecting cover device for preventing the infection of air harmful microorganisms with reference to the attached figure 3:

in fig. 3: when the gas outlet end (7) of the gas filtering channel is connected with one side of the gas shield, the gas filtering channel is an automatic gas switching device; when the gas inlet end (1) of the gas filtering channel is connected with the other side of the gas protection, the gas filtering channel is exhausted. When a human body inhales in the gas shield, negative pressure gas is formed in the gas shield, and under the action of the negative pressure gas, the gas isolation sheet (10) arranged in the exhaust channel is tightly matched with the raised step (9) of the vent hole (11), so that the negative pressure gas cannot enter from the exhaust filtering channel device. When the gas separation sheet (10) arranged on the air inlet body filtering passage device is separated from the raised step (9) arranged on the vent hole (11) under the action of negative pressure air, air enters the plush melt-blown filter material (4) from the gas inlet (1), various bacteria and novel coronaviruses in the air are intercepted and captured by the plush melt-blown filter material when harmful microorganisms in the air enter the filter material (4), when the gas passes through the separation net (3), the gas flow speed is slowed down, the harmful microorganisms in the air generate irregular movement, the opportunity of capturing and intercepting the harmful microorganisms by the filter material is increased, when the filtered gas passes through the vent hole (11) arranged on the gas separation plate (5), the gas separation film (10) is separated from the vent hole (11) under the action of negative pressure gas, and the negative pressure gas enters the gas protection cover from the gas outlet (7) through the gas passage (8) to provide clean oxygen required by a human body.

When the gas inlet (1) of the filtering channel is connected with the gas shield on the other side, the automatic switching device is an automatic switching device for the gas of the exhaust filtering channel, and the gas exhausted by a human body is filtered. When a human body exhales positive pressure gas in the gas shield, under the action of the positive pressure gas, the gas isolation sheet (10) arranged in the gas inlet channel is tightly matched with the raised step (9) of the vent hole (11) on the gas isolation plate (5), and the positive pressure gas cannot enter from the gas inlet filtering channel device. When the gas separation sheet (10) arranged on the exhaust gas filtering passage device is separated from the raised step (9) arranged on the vent hole (11) under the action of positive pressure gas, positive pressure gas exhaled by a human body enters the water absorption filtering material (4) from the gas inlet (1) of the exhaust gas filtering passage device, when the water vapor exhaled by the human body passes through the water absorption fiber cotton filtering material (4), a part of the water vapor is inhaled by the water absorption energy filtering material, the viscosity is generated on the filtering material, and when the human body is under the action of the airflow generated by the continuously exhaling positive pressure gas of the exhaust gas filtering passage, the redundant water vapor on the filtering material is taken away by the airflow generated by the positive pressure gas. The velocity of the gas flow is slowed down as the exhaled gas passes through the separation net (3), and the harmful microorganisms in the gas generate irregular movement, thereby increasing the interception and capture opportunities of the fiber cotton filter material. When positive pressure gas passes through the vent holes (11) arranged on the gas separation plate (5), the gas separation membrane (10) is separated from the vent holes (11), and the positive pressure gas is discharged outwards through the gas outlet (7) arranged on the gas channel.
