Description

In the present invention, by arranging the virus invasion prevention means and the air filtration unit in an independent state at the time of use, the feeling of wearing weight of the mask is reduced, and at the same time, the air is filtered into the gap space between the mask and the face. By blowing air to increase the pressure inside the mask, the absolute required amount of air for the user is secured, and the exhaled air of the user is guided to the outside air. The present invention relates to an air mask that can prevent the invasion of viruses floating near the periphery of the mask by being naturally discharged.

Conventionally, the effect of wearing a cloth (gauze) mask that is generally used is said to be effective in suppressing the spread of droplets scattered by pollen in the outside world or coughing or sneezing of others, but it floats in the air. It is said that it is not possible to sufficiently capture the fine droplets, and reuse by washing is not recommended from a hygienic point of view because it varies depending on the user's environment, but rather it is not recommended by some experts. It has been pointed out that there are many hygienic effects.

The hygiene / infection prevention effect required for conventional cloth (gauze) masks and non-woven fabric masks is to prevent bacteria and viruses contained in the pollen of the outside world and the droplets scattered by coughing or sneezing of others.
Especially in the case of cloth (gauze) masks, as is often said in comparison between baseball fields and balls, the gaps between the fibers of the cloth are larger than the size of the virus (about 0.1 micrometer), and most cloth (gauze) masks. While it is said to have no preventive effect, it has been reported that the virus that exercises brown while passing through the fiber net of the cloth has a certain capture effect.

Based on the efficacy of such a mask effect, various masks are provided according to the environment in which the mask is used.
For example, a cloth (gauze) mask is provided for the purpose of preventing the scattering of saliva particles and viruses contained in the droplets scattered by pollen of the outside world or coughing or sneezing of another person.

By the way, by Professor Yoshihiro Kawaoka of the Institute of Medical Sciences of the University of Tokyo, the permeability of the scattered virus in the experiment using the mannequin and the virus in the room where the virus does not leak is as high as 60 to 80%, and the content of the experiment is the American scientific journal " It is published in the electronic version of "msphere".
Further, the non-woven fabric mask is provided for the purpose of preventing dust and Brownian motion viruses generated during manufacturing and working in factories and the like in the gaps between the fibers of the non-woven fabric.
The transmittance of the scattered virus in the experiment using the mannequin and the virus is around 50%.

On the other hand, N95 masks are used as a source of infectious substances such as fine droplets and viruses (about 0.1 micrometer) floating in the air, coughing, sneezing, blood, secretions, saliva, sweat, and vomitus generated from patients. It is provided for the purpose of preventing harmful particles such as fine particles having a particle diameter of 2.5 micrometers or less floating in the atmosphere, such as a fine particle substance “PM2.5”, in addition to water, chemicals, dust and the like.
By the way, by Professor Yoshihiro Kawaoka of the Institute of Medical Science, the University of Tokyo, the transmittance of the scattered virus in an experiment using a mannequin and a virus in a room that does not leak the virus is as low as 10 to 20%.

However, all of the above masks have a problem that the air flowing in from between the mask and the face must be suppressed, and in order to solve the problem, it is necessary to bring the mask and the face into close contact with each other. In reality, due to the structure of the mask, it is not possible to prevent the invasion of viruses (about 0.1 micrometer) and the fine particle substance "PM2.5" from between the mask and the face. Many researchers claim that it has little protective effect.

The problem common to the conventional masks described above is that no powerful means (structure) that can suppress the outside air and the virus flowing in from between the mask and the face is taken. Therefore, a mask has been proposed in which a large amount of air is blown to the front of the face to prevent the invasion of the virus with that momentum.

For example, the health mask "Air" can protect the user's respiratory organs by forming an air curtain around the user's jaw to block the entry of external harmful substances, as well as having excellent skin adhesion. "Hazardous substance blocking health mask using a curtain" (Patent Document 1) has been proposed and has become a known technique.

However, the proposal of the "health mask for blocking harmful substances using an air curtain" is to cover a part of the face including the user's respiratory system and wear it to form the internal space and the main body. A close contact part that is placed along the circumference of the main body to make close contact with a part of the face, and ear hooks that are placed on both sides of the main body to fix the main body to a part of the face. In order to purify the external air and supply it to the internal space of the main body, air curtains are formed around the filter parts arranged on both sides of the main body and the main body to block the inflow of external substances. Although it is configured to include an air curtain composition means formed on the main body portion, the health mask includes an air curtain composition such as a filter, an air nozzle, an air intake port, and a blower fan. Since various components such as means are incorporated, the health mask itself has a complicated structure, which makes it bulky both in terms of weight and appearance, which increases the degree of wear fatigue of the user for long-term use. The cost is high, it cannot be used as a disposable item, and the air curtain method requires a large amount of air to be discharged, resulting in a feeling of wind pressure that is injected onto the generator and face. There was a problem that the generated sound became large.

Further, a mask has been proposed to prevent the invasion of a virus by discharging exhaled air and air from a gap at the periphery of the mask to the outside air.
For example, a "face mask provided with a fan device" (Patent Document 2), in which a fan for sucking air through the filter body of the mask is attached, has been proposed and is a known technique.

However, the proposed "face mask with fan device" has a shape that covers at least the nose and mouth of the wearer, is contoured by a peripheral edge, and further on the outer surface and the nose and mouth of the wearer. A filter body with an inner surface that forms an adjacent internal space, a fixing means that is attached to the filter body and configured to hold the filter body on the wearer's skin, and an air flow that passes directly through the filter body when activated. A face mask that employs a means equipped with a fan formed on the outer surface of the filter body to aspirate at least a portion of the face mask has a complex structure due to the inclusion of various components in the face mask itself. As a result, the degree of wearing fatigue of the user increases with long-term use, and there is a problem that a part of the view is blocked when working downward due to the sharp internal space at the tip. There were problems such as being expensive in terms of cost and not being disposable.

In addition, a "mask with a fan operated by a solar cell" (Patent Document 3), which uses a solar cell as a power source to filter harmful components in the air and supply clean air, has been proposed and has become a known technique. There is.

However, the proposal of the "mask with fan operated by solar cell" is to form a fan for taking in external air on the mask covering the mouth and nose, and this fan is provided with a filter to filter the external air. By forming a solar cell in the mask as a power source for operating the fan, the blower fan, the filter, and the solar cell are incorporated in the mask with a fan, so that the mask with a fan itself has a complicated structure. Therefore, due to the bulkiness in terms of both weight and appearance, there are problems that the degree of wearing fatigue of the user increases with long-term use, it is expensive in terms of cost, and it cannot be used disposable. At the same time, there was a problem in the effect of the structure in which the exhaled air of the user was discharged from the periphery of the mask during use.

In addition, an "infection prevention mask" (Patent Document 4), which is formed by a nasal mask equipped with a refreshing blower, has been proposed to prevent the invasion of bacteria such as influenza, pollen, allergens and dust in earnest. It is a known technique.

However, the proposal for such an "infection prevention mask" is to install a disinfectant deodorant filter on the outside air intake side of the sanitary ventilation substrate, and then install a pump or a micromotor with a fan inside the substrate, and further pass through. A battery that is provided with a ventilation flexible tube that allows sanitary air to pass through by sealing and fixing it to the inner front surface of the sanitary ventilation substrate, a nasal mask is closely attached to the extended tip of the ventilation flexible tube, and the sanitary ventilation substrate is also attached and supported. A headbar tube with a built-in headbelt is attached, a round rubber stopper is provided at the tip of the tube on the head side, and finally, from the headbelt with a built-in battery, through the inside of the headbar tube, with a power switch and a pump or fan. By adopting the means of wiring to the micromotor, the nasal mask is in close contact with the tip of the ventilation flexible tube, which forces nasal breathing and makes you feel tired when wearing it for a long time. There was a sense of discomfort, and there was a problem that there was a risk of virus invading from the nose due to the open mouth.

The applicant pays attention to the method of blocking the virus flowing in from the periphery of the mask body, and by arranging the virus invasion prevention means and the air filtration unit in an independent state at the time of use, the wearing weight of the mask is felt. At the same time, filtered air is blown into the gap space between the mask and the face to increase the pressure inside the mask, ensuring the absolute required amount of intake by the user and to the outside air of the user's exhaled breath. In the present invention, we have developed an air-type mask that can induce the discharge of the mask and prevent the invasion of viruses floating near the periphery of the mask by spontaneously discharging exhaled air and air from the gaps in the periphery of the mask. This leads to the proposal of "air mask".

In the present invention, by arranging the virus invasion prevention means and the air filtration unit in an independent state at the time of use, the feeling of wearing weight of the mask is reduced, and at the same time, the air is filtered into the gap space between the mask and the face. By blowing air to increase the pressure inside the mask, the absolute required amount of air intake by the user is secured, the exhaled air of the user is guided toward the outside air, and the exhaled air and air are released from the gap space around the mask. The present invention relates to an air mask that can prevent the invasion of viruses floating near the periphery of the mask by being naturally discharged to the outside of the mask body .

Conventionally, the effect of wearing a cloth (gauze) mask that is generally used is said to be effective in suppressing the spread of droplets scattered by pollen in the outside world or coughing or sneezing of others, but it floats in the air. It is said that it is not possible to sufficiently capture the fine droplets, and reuse by washing is not recommended from a hygienic point of view because it varies depending on the user's environment, but rather it is not recommended by some experts. It has been pointed out that there are many hygienic effects.

The hygiene / infection prevention effect required for conventional cloth (gauze) masks and non-woven fabric masks is to prevent bacteria and viruses contained in the pollen of the outside world and the droplets scattered by coughing or sneezing of others.
Especially in the case of cloth (gauze) masks, as is often said in comparison between baseball fields and balls, the gaps between the fibers of the cloth are larger than the size of the virus (about 0.1 micrometer), and most cloth (gauze) masks. While it is said to have no preventive effect, it has been reported that the virus that exercises brown while passing through the fiber net of the cloth has a certain capture effect.

Based on the efficacy of such a mask effect, various masks are provided according to the environment in which the mask is used.
For example, a cloth (gauze) mask is provided for the purpose of preventing the scattering of saliva particles and viruses contained in the droplets scattered by pollen of the outside world or coughing or sneezing of another person.

By the way, by Professor Yoshihiro Kawaoka of the Institute of Medical Sciences of the University of Tokyo, the permeability of the scattered virus in the experiment using the mannequin and the virus in the room where the virus does not leak is as high as 60 to 80%, and the content of the experiment is the American scientific journal " It is published in the electronic version of "msphere".
Further, the non-woven fabric mask is provided for the purpose of preventing dust and Brownian motion viruses generated during manufacturing and working in factories and the like in the gaps between the fibers of the non-woven fabric.
The transmittance of the scattered virus in the experiment using the mannequin and the virus is around 50%.

On the other hand, N95 masks are used as a source of infectious substances such as fine droplets and viruses (about 0.1 micrometer) floating in the air, coughing, sneezing, blood, secretions, saliva, sweat, and vomitus generated from patients. It is provided for the purpose of preventing harmful particles such as fine particles having a particle diameter of 2.5 micrometers or less floating in the atmosphere, such as a fine particle substance “PM2.5”, in addition to water, chemicals, dust and the like.
By the way, by Professor Yoshihiro Kawaoka of the Institute of Medical Science, the University of Tokyo, the transmittance of the scattered virus in an experiment using a mannequin and a virus in a room that does not leak the virus is as low as 10 to 20%.

However, all of the above masks have a problem that the air flowing in from between the mask and the face must be suppressed, and in order to solve the problem, it is necessary to bring the mask and the face into close contact with each other. In reality, due to the structure of the mask, it is not possible to prevent the invasion of viruses (about 0.1 micrometer) and the fine particle substance "PM2.5" from between the mask and the face. Many researchers claim that it has little protective effect.

The problem common to the conventional masks described above is that no powerful means (structure) that can suppress the outside air and the virus flowing in from between the mask and the face is taken. Therefore, a mask has been proposed in which a large amount of air is blown to the front of the face to prevent the invasion of the virus with that momentum.

For example, the health mask "Air" can protect the user's respiratory organs by forming an air curtain around the user's jaw to block the entry of external harmful substances, as well as having excellent skin adhesion. "Hazardous substance blocking health mask using a curtain" (Patent Document 1) has been proposed and has become a known technique.

However, the proposal of the "health mask for blocking harmful substances using an air curtain" is to cover a part of the face including the user's respiratory system and wear it to form the internal space and the main body. A close contact part that is placed along the circumference of the main body to make close contact with a part of the face, and ear hooks that are placed on both sides of the main body to fix the main body to a part of the face. In order to purify the external air and supply it to the internal space of the main body, air curtains are formed around the filter parts arranged on both sides of the main body and the main body to block the inflow of external substances. Although it is configured to include an air curtain composition means formed on the main body portion, the health mask includes an air curtain composition such as a filter, an air nozzle, an air intake port, and a blower fan. Since various components such as means are incorporated, the health mask itself has a complicated structure, which makes it bulky both in terms of weight and appearance, which increases the degree of wear fatigue of the user for long-term use. The cost is high, it cannot be used as a disposable item, and the air curtain method requires a large amount of air to be discharged, resulting in a feeling of wind pressure that is injected onto the generator and face. There was a problem that the generated sound became large.

Further, a mask has been proposed to prevent the invasion of a virus by discharging exhaled air and air from a gap at the periphery of the mask to the outside air.
For example, a "face mask provided with a fan device" (Patent Document 2), in which a fan for sucking air through the filter body of the mask is attached, has been proposed and is a known technique.

However, the proposed "face mask with fan device" has a shape that covers at least the nose and mouth of the wearer, is contoured by a peripheral edge, and further on the outer surface and the nose and mouth of the wearer. A filter body with an inner surface that forms an adjacent internal space, a fixing means that is attached to the filter body and configured to hold the filter body on the wearer's skin, and an air flow that passes directly through the filter body when activated. A face mask that employs a means equipped with a fan formed on the outer surface of the filter body to aspirate at least a portion of the face mask has a complex structure due to the inclusion of various components in the face mask itself. As a result, the degree of wearing fatigue of the user increases with long-term use, and there is a problem that a part of the view is blocked when working downward due to the sharp internal space at the tip. There were problems such as being expensive in terms of cost and not being disposable.

In addition, a "mask with a fan operated by a solar cell" (Patent Document 3), which uses a solar cell as a power source to filter harmful components in the air and supply clean air, has been proposed and has become a known technique. There is.

However, the proposal of the "mask with fan operated by solar cell" is to form a fan for taking in external air on the mask covering the mouth and nose, and this fan is provided with a filter to filter the external air. By forming a solar cell in the mask as a power source for operating the fan, the blower fan, the filter, and the solar cell are incorporated in the mask with a fan, so that the mask with a fan itself has a complicated structure. Therefore, due to the bulkiness in terms of both weight and appearance, there are problems that the degree of wearing fatigue of the user increases with long-term use, it is expensive in terms of cost, and it cannot be used disposable. At the same time, there was a problem in the effect of the structure in which the exhaled air of the user was discharged from the periphery of the mask during use.

In addition, an "infection prevention mask" (Patent Document 4), which is formed by a nasal mask equipped with a refreshing blower, has been proposed to prevent the invasion of bacteria such as influenza, pollen, allergens and dust in earnest. It is a known technique.

However, the proposal for such an "infection prevention mask" is to install a disinfectant deodorant filter on the outside air intake side of the sanitary ventilation substrate, and then install a pump or a micromotor with a fan inside the substrate, and further pass through. A battery that is provided with a ventilation flexible tube that allows sanitary air to pass through by sealing and fixing it to the inner front surface of the sanitary ventilation substrate, a nasal mask is closely attached to the extended tip of the ventilation flexible tube, and the sanitary ventilation substrate is also attached and supported. A headbar tube with a built-in headbelt is attached, a round rubber stopper is provided at the tip of the tube on the head side, and finally, from the headbelt with a built-in battery, through the inside of the headbar tube, with a power switch and a pump or fan. By adopting the means of wiring to the micromotor, the nasal mask is in close contact with the tip of the ventilation flexible tube, which forces nasal breathing and makes you feel tired when wearing it for a long time. There was a sense of discomfort, and there was a problem that there was a risk of virus invading from the nose due to the open mouth.

The applicant pays attention to the method of blocking the virus flowing from the periphery of the mask body, and by arranging the virus invasion prevention means and the air filtration unit in an independent state at the time of use, the wearing weight of the mask is felt. At the same time, filtered air is blown into the gap space between the mask and the face to increase the pressure inside the mask to ensure the absolute required amount of breathing by the user and to direct the exhaled air of the user to the outside air. We have developed an air-type mask that can prevent the invasion of viruses floating near the periphery of the mask by naturally discharging exhaled air and air from the gap space around the mask to the outside of the mask body . This leads to the proposal of the "air mask" in the present invention.
