Description

Antivirus fully enclosed combination hood

technical field

The invention relates to the technical field of virus protection, in particular to an anti-virus fully enclosed combined headgear.

Background technique

The existing anti-virus protection products for the war epidemic are based on the ancient Persians in religious ceremonies to block the unclean breath, saliva, and droplets of the laity. In the 19th century, people invented masks to fight the plague and prevent infectious diseases based on the cloth of the ancestors. Later, they invented protective products such as anti-virus hooded protective clothing, gloves, shoe covers, goggles, etc., which are still in use today. Humans have discovered that air-borne virus bacteria can infect human wounds. At the same time, people have found that when speaking, the saliva and droplets of virus bacteria will be brought into the face, eyes, mouth and nose of the human body, resulting in the spread of respiratory tract infections, injuring the internal organs of the human body, and aggression and attacking the human body. Cells, destroy human immunity and endanger human life. Many protective products have made special contributions to human epidemic infection and antiviral bacteria and are widely used. At the same time, it is more and more cunning, the types of viruses are more and more, more and more ferocious, more and more aggressive, and the scope of harm to people's lives is becoming more and more extensive, especially the facial respiratory tract that is easily contagious to the majority of people. The source of the eye, the aggressiveness of the mouth and nose is becoming more and more fierce, resulting in the traditional mask's ability to protect against viruses, powerless, and the insurance factor is greatly reduced. The gap is too large to be invaded by the virus.

Existing masks, for many years, masks are only in shape, (flat, convex) material, (melting cloth, graphene, charcoal, activated carbon, cotton yarn, non-woven fabric, sponge, etc.) layers, (3-- 16 layers ranging) color (colorful), sterilization and bacteria isolation, (nanotechnology, microfiber, electrostatic treatment, etc.) and other aspects to be changed.

For example, Chinese invention patents disclose:

1. An anti-haze mask with a multi-layer structure (application number: 201910888246X) is composed of an inner layer, a middle layer and an outer layer, the inner layer is made of soft cloth, and the middle layer and the outer layer are made of shapeable materials. A first air inlet and a first exhalation port are respectively opened on both sides of the outer layer, a miniature silent air intake fan is arranged at the first air inlet, a miniature silent exhaust fan is arranged at the first air outlet, and a miniature silent exhaust fan is arranged at the first air inlet, and a There are a second intake port and a second exhalation port, the first intake port and the second intake port, the first exhalation port and the second exhalation port are respectively communicated through the intake passage and the exhaust passage, and the intake passage There is an intake check valve inside, an exhaust check valve is arranged in the exhaust passage, and an air filter layer is arranged between the first air inlet and the intake check valve; the breath monitoring unit includes a controller and a breath monitoring module , the breathing monitoring module is used to monitor the breathing frequency of the user.

2. A graphene antibacterial breathable thermal mask (application number: 2019109692443), comprising a base cloth, one side of the base cloth is provided with a fixing strip, the bottom of the side of the fixing strip away from the base cloth is provided with an adjusting sheet, and the adjusting sheet is provided with several Through holes, a fixing button is provided between the end of the adjustment sheet close to the fixing strip and the fixing strip, the top of the fixing strip on the side away from the base cloth is provided with a mask strip that matches the adjustment sheet, and the side of the base cloth away from the adjustment sheet is provided with a mask strip. There is a fixing belt, a warm cloth is arranged on the top of the base cloth, and an antibacterial cloth piece mechanism matched with the base cloth is arranged between the warm cloth and the base cloth. The two sides of the warm cloth are respectively provided with connecting strips, the connecting strip and the fixed strip are connected by movable buttons, and the top of the warm cloth is provided with a fixed and tightening block matched with the antibacterial cloth piece mechanism. Beneficial effects: It has better effects of keeping warm and heat, antibacterial, antibacterial, skin-friendly and breathable, more flexible to use, and adaptable to more environments and people.

At present, the core product of masks is melting cloth. Melting cloth is the best product among the current masks. It is only for the current masks that are irreplaceable and missing products. Because masks are veneer products, they are not easy to be too thick. The requirements of the mask are thin, soft, and conform to the face shape. The three elements of the mask are: 1. Block viruses, 2. Ensure ventilation, and 3. The shape is docile, but they restrict each other, oppose, contradict each other, and it is difficult to adjust and unify each other. Therefore, wearing a mask, especially in the high-risk areas of the intensive care unit and emergency room, the risk of wearing a mask is still very high. The virus itself is actually parasitic on the polluted water vapor or atmospheric powder or saliva and saliva, and enters the human body. Knowing this, you should know that there are better products to protect the virus from invading the human body, not just an important layer of melting cloth can completely prevent the virus from invading.

At present, no matter how good the masks are, there is still the problem of poor sealing. That is, N100, N95, and N90 masks are only the level requirement indicators of the technical indicators of the front shielding and shielding virus and air permeability, and they can only be used as general low-level protection. , Because no matter how good the mask is, in theory, it is absolutely impossible to effectively block the invasion of the virus, because it is absolutely impossible for the mask to seal too well. The larger the indentation on the skin, the greater the chance of infection by skin rupture. Usually, if you can breathe normally, there must be a direct gap between the virus inlet and outlet. The better the mask material, the tighter the front seal, the harder it is for people to breathe, and the more difficult the mask material is. Poor, the greater the possibility of virus intrusion on the front of the mask, the quality of the material and the invading virus in the surrounding space have become a pair of contradictions, which cannot be reconciled. In addition, the masks, hats, goggles, and front goggles in a complete set of protective clothing can not achieve the best facial protection effect. I must know how troublesome it is to wear such a set of weapons, especially how uncomfortable it is to wear it for a long time. The longer the face mask is attached, the greater the chance of breaking the skin, the more difficult it is to breathe, and the inability to eat and drink after working for a long time. Not good, the risk of direct virus infection is still very high if the closure is not rigorous. In reality, there is no mask that ensures a fully enclosed form to effectively protect against viruses, and there is no product that is a fully enclosed form of protective clothing for effective protection. Super-infectious anti-virus fully enclosed protective clothing.

Therefore, it is necessary to propose an anti-virus fully enclosed combined head cover for the above-mentioned problems.

The total thickness of the multi-layer mesh can be designed to be about two centimeters, which is more than ten times thicker than the thickness of the mask. Medical research on viruses.

The present invention is scientific and effective, ensuring total sealing to block virus invasion, preventing direct inflow and outflow of viruses from the mouth, nose, and eyes, which are the main breathing areas of the human body, causing cross-infection, virus invasion, replication and diffusion, and effectively blocking droplets, aerosols and other transmission of infectious viruses in the human body. The anti-virus head covering directly penetrates the face, neck and even the entire head, especially this head covering is simple and convenient to wear. Compared with masks, the protective clothing is more comfortable to wear for a long time, and the wearer can move to a safe area without removing it after working continuously for too long. Under the hood, the basic problem of eating, drinking and supplementing energy can be solved by simply removing the mask cover. More importantly, the ventilation system of the present invention can be used in an infinitely large area. The system is very simple and effective to block the spread of viruses. The multi-layer ventilation, virus and disease isolation net made of special materials in this product can deposit, absorb, absorb, and collect a large number of harmful viruses, which is convenient for uniform replacement and treatment of viruses. The eye mask of the present invention The system can also make it easier for any sighted people to see the field of vision more easily and solve the problem of medical staff's vision. The cover can be used repeatedly until it is damaged, which greatly reduces the production cost of anti-epidemic and anti-virus protective products.

According to the shape of the human head, a mask similar to the human face and suitable for the human facial features is designed by injection molding a transparent material suitable for the anti-virus fully enclosed combination function, so that the entire face of the person is completely in the closed state of the transparent material production mask. According to the air required for natural breathing of the human body, there are multiple bypass breathing holes and holes for oral diet and ventilation, that is, spare holes for the mouth and nose, breathing holes on both sides of the face and on the forehead, the size of the holes and the total thickness of the multi-layer ventilation network density It is determined according to the size of human air breathing and the blocking virus to ensure complete and effective blocking, deposition, adsorption, and collection of viruses, and to ensure the normal amount of breathing air required. It is disassembled into an integrated device, which completely eliminates the inflow and outflow of droplets, aerosols and direct and indirect contact with the virus in the front, nose, eyes, and an anti-fogging ventilation hole is designed next to the eye lens to ensure that the lens is free from fogging. Clarity, the back of the head and the lower part of the neck are made of breathable fabric. The overall rear opening and closing type is organically combined with the mask perimeter snapping and detachable device or the tight dead closing type. A fixed and adjustable head maxilla clip is designed on both sides of the top of the mask. A fixed and adjustable head and mandible seat is designed on each side of the lower part of the mask, so as to facilitate various head shapes to comfortably and firmly fix the hood.

The anti-virus fully-enclosed combined headgear of the present invention is mainly suitable for the protection of the human epidemic, the respiratory tract, and the face, which are highly susceptible to high infection. Therefore, the most important thing is how to scientifically design reasonable details on the headgear and mask, and how to ensure that both the fully-enclosed and free To attract virus infection and spread to infect others, it can also ensure that the normal respiratory system circulating air needed by the human body is necessary and wear is more comfortable, convenient and reliable than the conventional masks and protective clothing for the head and face that have been used for many years.

In the epidemic of lethal human-to-human virus infection, the most important thing for people to effectively control human-to-human transmission of the virus, animal-to-human transmission and other causes of infection is to control and avoid human-to-human and other factors. Contact, because whether it is spitting, droplets, aerosols and contact transmission that carry the virus, the most fear is that the virus will directly enter the respiratory tract, mouth and nose. The commonly used mask protection is that people directly enter and mask around the mask that is not rigorous in normal breathing. Due to poor quality, in order to avoid infection in this series of situations, the present invention adopts the method of breathing bypass ventilation to isolate viruses and bacteria, and open a convex cylinder hole in front of the transparent material in the oral and nasal cavity, and the convex cylinder A special multi-layer mesh to isolate viruses and bacteria is installed in the middle of the holes, and a removable transparent material mask cover is installed in front of the ventilation holes to facilitate complete sealing in the intensive care unit and high-virus areas.

Two convex conjoined rectangular holes are respectively opened at the symmetrical sides of the two sides of the mask, which are used as a multi-layer mesh for speech amplification and ventilation, which is specially designed to isolate viruses and bacteria, because the multi-layer mesh can effectively perform deposition and adsorption. Absorbs and collects all the harmful viruses and bacteria that pass through, ensuring that all the required breathing air is filtered by a multi-layer mesh, and the multi-layer mesh can be easily replaced.

A convex conjoined cuboid hole is also opened above the forehead of the mask, so that the bottom of the cuboid is above the top of the head, which is convenient for the person's head to support the entire hood smoothly, so as to satisfy the relative fixation of the hood and better ensure the goggles of the hood. The firm positioning, as a multi-layer mesh for speech amplification and breathable special virus and bacteria isolation, the same multi-layer filter mesh also plays an effective role in deposition, adsorption, absorption, and collection of all harmful viruses and bacteria passing through. All the required breathing air is filtered by a multi-layer mesh, and the multi-layer mesh can be easily replaced.

The purpose of the multi-layer filter screen is to avoid contact with the mouth and nose in a short distance from the front. The purpose of the multi-layer filter screen is due to the total demand of the normal breathing air volume of the human body. In addition, the larger the total area of the filter screen, the greater the total air flow required, and the effect of human breathing. The better it is, the better the effect of filtering deposition, adsorption, absorption, and collection of all the harmful viruses and bacteria that pass through.

Auxiliary breathing tube: Leave a breathing tube connector on the top of the mask to facilitate plugging in the auxiliary breathing tube hovering above the head to increase the amount of breathing air needed by the human body. The 1.5-meter-long breathing tube can better ensure the circulating air required by the body, and a multi-layer virus-isolating filter device is installed on the tube head.

A spare oxygen nozzle; a breathing tube connector is left under the mask, that is, the neck of the human body, which is convenient for plugging in a spare oxygen tube. The tube head is equipped with a multi-layer virus-isolating filter device, which is also to increase the amount of breathing air required by the human body. In the intensive care room or emergency room or any place where the body needs to breathe, plug in the oxygen cylinder 25 through the spare oxygen tube to deliver oxygen to ensure normal breathing.

The goggles are made by opening a concave surface parallel to the mask glasses to form an outer cuboid bell mouth mask body in the long direction of the bottom. The purpose of the bell mouth is to achieve a beautiful appearance and a wide field of vision. Integrated, the lens is selected according to the vision, because a little gas will be generated when the eyes are opened and closed, so there are anti-fogging and ventilation holes on the sides of the two lenses.

In order to ensure that the hood is fixed firmly and stably, a fixed and adjustable upper jaw seat is specially designed on each side of the upper face of the mask, and a fixed and adjustable head jaw seat is designed on each of the lower sides of the mask to facilitate the comfort of various head shapes. Holds the hood firmly and lastingly.

The multi-layer poison-proof and breathable net adopts a variety of materials, such as melted cloth, activated carbon, non-woven fabric, gauze, sponge and other materials, which are organically combined to produce a composite poison-proof breathable material multi-layer net standard part. It is well known that the multi-layer thickness of various masks is also thin, and the key material of its main function is polypropylene processed into fine fiber melt cloth for electrostatic treatment. The density is very large, and the air permeability must be greatly reduced due to the extremely high density, which is close to a complete shielding state. The basic theory that the stronger the ability to block viruses is to produce special materials with good air permeability and stronger ability to disinfect and block viruses.

The lower neck circumference and the overall cover of the back of the head are sewn with multi-layer breathable virus-proof textile materials, and the rear opening and closing type is adopted, which is convenient to wear and fastened and fixed firmly. The top fabric is reinforced with strip-shaped light material support points to ensure that the fabric is not tight The head is attached to the head to achieve the ventilation and heat dissipation effect of the head, so as to make people comfortable when wearing it; the connection method between the mask and the lower circumference of the neck and the overall cover of the back of the head can adopt multi-point snap connection and full adhesive connection. The bottom edge fabric of the cover can also be connected with the protective clothing as a whole.
