Japan Utility Model 003227863 Japan Utility Model 003229764 Japanese Patent Application Laid-Open No. 2008-031581 Japanese Patent Application Laid-Open No. 2012-533327 International WO / 2010-047382 International WO / 2017-057168

According to the non-patent literature, a product has been developed for the first link, in which the cooling surface of the Pelche element is brought into direct contact with the neck to survive the intense heat with Kyushu Electric Power from an external power source. In addition, suitable prior patent documents could not be searched in Japan. In addition, for the second link, a product has been developed that makes breathing easier by sucking air with an electric fan to make breathing easier.

Due to the recent spread of coronavirus, it is necessary to wear a mask even in the hot summer months, but the hot air in breathing stays in the mask, and the gas in the mask becomes a temperature and high humidity equivalent to or higher than the body temperature. Therefore, there is a problem that heat cannot be discharged for the purpose of adjusting the body temperature and temperature by breathing, and there is a concern about health hazards such as heat stroke and heat stroke.

The concern about health hazards cannot be dispelled by not stably inhaling gas below body temperature outdoors in midsummer. Therefore, as a conceivable method for solving this problem, heat exchange between the inside and the outside is performed with a mask provided with a Perche element, as in the case of the site information referred to in the non-patent documents in the above-mentioned prior documents. It can be considered to be configured to have a cooling surface of the Pelche element inside.
Further, it may be realized by a method such as using a paint having a cooling effect by a special coating developed in recent years.

However, when the inventor actually created it, even if the cooling surface of the Pelche element was turned inward, the temperature dropped sufficiently in breathing. In particular, the temperature of the gas generated during respiration is inevitably equivalent to the body temperature, and the result is that the problem of not being able to sufficiently suppress the temperature rise of the body due to the transpiration effect associated with the exhaled exhaust is further found.

In such a situation, in order to improve the waste heat efficiency associated with respiration, including the evaporation effect in the waste heat required by body temperature associated with respiratory exhaust, it is necessary to widen the contact area of the exhaled gas in the cooling section. By further providing a comb-shaped heat exchange part that can expand the contact surface with the air during breathing on the cooling surface of the Pelche element, the part where the gas during breathing stays inside the oral cavity and the mask can be prevented. In addition to the provision, a comb-shaped additional cooling section was provided between the cooling surface and the oral cavity to efficiently solve the problem.

In addition, since the moisture of the exhaled air condenses on the comb-shaped cooling part of the present case as the exhaled air cools, the condensed water is discharged to the outside by a drain hose or the like, and the discharged water is led out to the heat-generating waste heat surface of the present case. By evaporating the moisture that has condensed inside on the waste heat surface, the heat dissipation efficiency is improved by utilizing the evaporation waste heat effect that accompanies the vaporization of the condensed moisture, and achieving higher performance waste heat or improvement of cooling efficiency. You may be able to do it.

Furthermore, it can be configured to make breathing safe by reducing the exposure of the human body to viruses, bacteria, chemical poisons, dust, etc. by using a wireless communication function or the like.

By providing a comb-shaped heat exchange component having a height of about 0.3 cm to 5 cm on the cooling surface of the Pelche element instead of simple surface cooling like the neck cooler in Non-Patent Document 1 described above, exhalation and inspiration are performed. It was confirmed that the temperature of the air can be lowered below the outside air temperature and the exhaled air temperature.

Further, with respect to the utility model 003227863, regarding the mask antibacterial property in a normal mask, it is described as "cloth subjected to antibacterial treatment". In the present invention, since the antibacterial design by the metal ion by the heat exchange metal part or the like is made, the antibacterial design is fundamentally different from the cloth subjected to the general antibacterial treatment, so that there is a special effect.

Further, for the utility model 003229764, the gas by inhaling the outside air by the fan is electronically cooled. Since the new plan does not exchange heat with the stagnant gas as in the present invention, but performs forced intake and forced cooling by a fan, the space that comes into contact with the cooling unit at the same time in the new plan and the present invention is relatively high. There is a problem that the cooling performance is remarkably deteriorated because the residence time of the gas in the new invention is different from that of the present invention and the residence time of the new proposal is shorter than that of the present invention. The purpose of the present invention is to lower the temperature of the gas staying in the mask by natural breathing of a person or mere fan intake instead of dynamic intake cooling by a forced intake fan, and the gas stays in the mask at a temperature equivalent to body temperature. It has a special effect of sufficiently cooling the gas.

Japanese Patent Application Laid-Open No. 2008-031581 describes that a semiconductor element cools a refrigerant and exchanges heat at a contact portion with clothes to cool a cooling component attached to clothes and lower the body temperature. The present invention cools the exhaled breath directly without using a refrigerant or the like to lower the temperature of the gas sucked into the lungs in the body instead of the body surface, thereby promoting cooling from the body and exchanging gas in the lungs and at the same time blood. It has the effect of improving the body cooling efficiency associated with the blood circulation of the body caused by the blood cooling associated with heat exchange.

Regarding Japanese Patent Application Laid-Open No. 2012-533327, according to the section 0053 of the application contents, it is pointed out that when the inside of the mask is washed with water, it may adversely affect electrically moving parts such as a fan. The present invention has a special effect that the problem described above does not occur because there is no electrically moving part in the cleaning part.

With respect to the international application WO / 2010-407382, the refrigerant is cooled so that the refrigerant is circulated in the pad attached to the body to cool the body. Since the present invention does not use a cooling medium, a pump or the like is not required, power efficiency is improved, and the body temperature is lowered by heat exchange of blood in the lungs.

For international application WO / 2017-057168, the gas inside the part is cooled by the part that covers the mouth and nostril with a cooling medium with water to lower the temperature of the breathing gas, and the exhaled breath is exhausted by the part using the valve. By doing so, the heat generated by the exhaled air in the parts does not stay. Since the present invention does not use a refrigerant as in the international application, a refrigerant circulation pump or the like is not required, power efficiency is improved, and the configuration is very compact.
At this time, by providing a small heat exchange part that can form and store the heat exchange part in a very narrow space such as the gap between the mask and the body, which is the front part of the lip and the lower part of the nostril, it is very much compared with the conventional product. By enabling air cooling per unit volume and efficiently cooling the exhaled breath that has risen due to body temperature, it avoids adverse effects on the body even in places where the ambient temperature is about or higher than body temperature. It is possible to do.
In particular, regarding this international prior application, since the refrigerant is water, it is virtually impossible to cool below the freezing point (even if it is salt solution, it is about -4 ° C). In comparison, in the present invention, an electronic cooling unit that directly exchanges heat can provide a sufficiently low negative temperature, but a cooling mask that uses water or the like for safety as a refrigerant sufficiently lowers the intake gas temperature. It has the effect of solving the problem that it is impossible.

That is, in all the above-mentioned prior cases, in the heat exchange in the design in which the inside and the outside of the mask unit are surely separated by the filter, the heat exchange is not directly performed without using the refrigerant, and the refrigerant is used. The heat inside the mask is cooled by a dedicated refrigerant cooling device unit installed separately, and there is a problem that the power efficiency is very poor, especially because a pump or the like is used to convey the refrigerant. .. Alternatively, since the gas that is forcibly inhaled is directly cooled, the heat exchange structure is very inefficient. Furthermore, since a large fan is driven without using a refrigerant, there are some that have significantly deteriorated power efficiency and floor area ratio. In addition, the filter has a cooling structure between the cooling section and the face line, which cools the exhaled air after passing through the filter and sufficiently contaminates the outside exhaust even when the user is affected. It is structured so that it does not produce exhaled breath. Furthermore, by configuring the intake fan on the right side, the cooling unit in the center, and the exhaust fan on the left side, it is possible to improve the circulation of exhaled air.

The present invention improves the volume ratio and power efficiency, reduces the possibility of mechanical system failure such as pumps, and does not forcibly cool a large amount of air by forced suction by a fan, so large intake air It is no longer necessary to extremely increase the cooling performance per unit time in forced inspiration by a fan, and not only is it possible to lower the temperature of the amount of air required for respiration with sufficiently low power, but also the exhalation filtering is sufficient. It can be done, and even if the mesh on the outside of the mask is rough due to the circulation of the fan, the exhaled air of the affected person can be filtered and exhausted.

As described above, as compared with the conventional conditions, the present invention cools the exhaled air having a body temperature that stays in the mask, and also uses a cooling unit having a small volume to cool the gas that has a body temperature that stays in the mask due to respiration. By cooling the gas, the gas in the mask having a high temperature can be cooled, and the gas required for respiration can be sufficiently cooled within the residence time of exhaled breath accompanying respiration.

First, it will be described from the appearance side based on FIG. Although the mask shown in this photo is made of urethane and has some thickness, there is a problem that it is not strong enough to fix the cooling parts to the mask. To solve this problem, the mask is used as a spacer or frame. By equipping the mask with parts made of resin or the like, the strength is such that the cooling unit can be held. The mask is not limited to the urethane mask, and the mask may be made of fibers having a certain strength made of an appropriate mesh material. Further, the electronic cooling unit may be appropriately provided with an electric fan so that the cooling efficiency can be improved.

As for the appearance, as shown in FIG. 1, the cooling element is configured to operate by USB power supply or the like from the outside, and a mask-integrated cooling unit can be provided by the electronic cooling element. This power supply may be a solar cell or the like, and the cooling unit is provided with an electronic heat exchange unit such as a Pelche element, which makes it possible to have a simple structure. Further, instead of air cooling as shown in the image, a larger heat exchange unit such as liquid cooling may be provided, but a lightweight Perche element or the like is preferable in terms of weight.

The cooling unit configured in this way has a structure in which a volume sufficient to temporarily retain gas during respiration exists in the gap between the cooling unit and the face, and the structure of the face portion and the cooling unit is When observed from the side, the structure of the gap between the face line 4000 and the comb-shaped cooling unit 3001 is assumed in FIG. Then, a filter unit 3002 used for the mask is configured between the oral cavity / nasal cavity portion associated with the face line 4000 of the mask and the comb-shaped heat exchange cooling unit 3001. It is preferable to consider that the performance of the mask itself can be arbitrarily designed due to the difference in the material of the filter portion.

The comb-shaped cooling unit configured as described above can sufficiently secure the volume in which the respiratory gas stays. With this configuration, it is possible to secure a sufficient volume for heat exchange associated with cooling in a short time of the breathing timing of one breath, so that the intake air in the physical heat exchange associated with breathing can be sufficiently cooled. It is possible to construct a mask with a filter that can drastically reduce the possibility of inhaling the gas whose temperature has risen again due to exhalation, and can prevent the waste heat efficiency associated with respiration from deteriorating by using the mask regularly. Furthermore, as a configuration for improving breathability, the mask material is made of a mesh-like material, or the inside is made positive pressure by using an electric fan so that the load in breathing is reduced. May be good.

FIG. 2 shows the appearance of the present invention. The mask consists of a mask that is stronger than a mask made of ordinary rubber strings, and if necessary, a fixture 1002 (electronic cooler) made of resin or the like to support the electronic cooler 1001 that is heavy as it is. The electronic cooling mask 1000 is configured by fixing the mask with a cooler), and the fixture 1002 may not be provided as long as the mask material has sufficient strength.

FIG. 3A shows a state in which the comb-shaped heat exchange cooling unit 3001 is configured inside the mask of the present invention. Further, in (b), a filter, which is the main function of the mask, is configured and fixed on the comb-shaped heat exchange portion. Further, the circular portions provided on the left and right sides when viewed from the center of FIGS. 3 (a) and 3 (b) are provided with a valve-shaped structure when exhaling (exhausting), thereby exhaling (exhausting). ) May be considered to be configured so that it can be easily discharged. Further, the performance of the mask may be considered to change depending on the performance of the filter shown in (b).

Further, since it is fully conceivable that dew condensation occurs in the cooling part of the present invention, silver or copper is used as a countermeasure against the growth of mold and germs caused by the increase in humidity caused by the dew condensation and the drain hose for draining to the outside. By using appropriate antibacterial and bactericidal materials such as ion coats such as, it is configured to reduce the risk of respiratory infections used in the present invention, and deodorization by electrical plasma or ions. It may be configured to further have a function such as sterilization.

It is more effective that the comb-shaped heat exchange metal part for expanding the gas contact area of the cooling part has a high thermal conductivity, and the heat exchange part due to undulations of about 3 mm is used to expand the contact area. It is possible to design a wide area such as a heat exchange part with undulations of about 5 cm, and it is preferable that the heat exchange efficiency is improved thermodynamically, and the inventor is about 3 mm to 15 mm. We are conducting experiments using the heat exchange parts of comb-shaped, fin-shaped, spiny-shaped, columnar and their forest-shaped parts with the height of. Further, by stacking a plurality of electronic cooling elements, such as by stacking two electronic cooling elements, it is possible to configure the structure so that sufficient cooling can be realized more efficiently for the user.

Further, the moisture generated by the above-mentioned dew condensation is discharged from the inside to the outside of the mask by the drain hose, and the dew condensation discharged by the drain hose or the like to the heat dissipation part of the heat exchange part composed of electronic parts provided on the outside. The overall cooling performance of the mask of the present invention may be improved by improving the heat dissipation efficiency on the outside by evaporating the moisture on the heat radiating portion by inflowing the moisture accompanying the above.

Further, the inside of the heat exchange component is provided with the drain hose 5001 in which the structure of the heat exchange part of the cooling part and the waste heat part formed by sandwiching the semiconductor cooling element 1004 is directed from the inside to the outside as shown in FIG. By flowing the moisture condensed on the cooling surface to the evaporation waste heat section 5002 on the outside of the mask, it is possible to further improve the waste heat efficiency by absorbing heat as vaporization heat accompanying the evaporation of the condensed moisture.

Further, the filter unit 3002 in the present invention can be replaced with PM2.5 compatible or N95 equivalent by using an arbitrary fixing means to change the performance according to the purpose of use, or a spring or ratchet on the cooler fixture 1002 part. By providing a fixing mechanism having a removable function by a mechanism or the like so that the electric fan portion and the cooling portion 1001 with an electric fan can be removed, the product according to the present invention can be cleaned more easily. May be possible.

In addition, place the microphone anywhere inside the mouth of the mask filter or mask product, such as between the parts outside the mask and the filter, inside the filter, or inside the parts for fixing the filter to the mask. , A speaker is provided on the outside of the mask to transmit the voice inside the mask to the outside, and a wireless communication function linked with the voice signal picked up by the microphone and the speaker or earphone (more specifically, Wi-Fi, Bluetooth, etc. * Registration Remote communication may be realized by means of (including trademarks), and through circuits and programs that change or improve the sound and / or sound quality of the voice obtained in the microphone, such as a voice changer, equalizer, and noise canceller, 4011 in FIG. Depending on the component configuration such as 4012 and 4013, the sound heard to the outside may be optimally configured, or noise reduction may be performed.

By providing the mask with such a function, it is possible to improve and / or facilitate voice communication with the patient by providing the mask to the patient in the isolated state. In addition, it may be configured to work with a smartphone. Furthermore, the USB connection for power supply should have a data link function, and a compute module such as Bluetooth (registered trademark) or Wi-Fi (registered trademark) should be externally provided or combined with a battery. It may be configured as.

Furthermore, even if it is configured to sterilize inspiration and exhaled breath with an electronic sterilization device (generators such as ions, plasma clusters, metal ion generators, ozone generators, hypochlorous acid, etc. * including registered trademarks). good. An electric fan is provided so that such sterilized air circulates appropriately, an electric fan is provided so that the inside of the mask has an appropriate positive pressure as described above, and a fan for enhancing exhaustability is provided. Alternatively, antibacterial treatment may be applied to the parts used for the mask in order to avoid an increase in germs due to humidity. Such electronic sterilization devices may be configured to reduce the risk of infection due to exhaled breath from the patient by having a structure for disinfecting the exhaled breath of the patient as much as possible by, for example, holding it on the exhaust valve side.

Furthermore, by using a solar cell, it is possible to charge the battery at the same time during use outdoors, and by further providing a heat exchange medium circulation unit for liquid cooling on the outside of the electronic heat exchange component, the cooling structure is duplicated. By using the structure, it is possible to realize high temperature heat exchange efficiency in a dual medium cooling structure as used in a nuclear fuel reprocessing furnace or the like. This dual medium may be realized by a multi-order cooling configuration such as a structure of liquid cooling or gas cooling from an electronic heat exchange element, gas cooling from an electronic heat exchange element, and further liquid cooling. .. It should be noted that the battery as a power source can be mounted by any method regardless of whether it is a built-in battery or an external wiring connection regardless of priority radio.

Further, according to FIGS. 6A and 6B, the air sucked from the intake hole 6001 by a fan or the like is exhausted by a fan or the like from the exhaust hole 6003 via the comb-shaped cooling portion of the cooling portion 6002. By separately fixing the filter with a fixture such as 6004 so as to cover the cooling part, etc., the user can separate the filtered air in breathing from the forcedly circulated air. Even if it is affected, it can be configured so that bacteria and viruses are not exhausted to the outside. Of course, I would like you to think that the configuration of the present invention can be implemented without intake / exhaust holes and forced circulation by a forced fan, and it is also possible to implement it without intake / exhaust holes and without an exhaust valve. I want you to think about it.

In addition, both specifications described as intake / exhaust fans may be configured to have only intake or only exhaust, or the inside can be replaced with a mask with a cooler (1001/3009) as a mask exterior. The fact that the cooling unit 3001 is configured between the filter unit (3002) means that the cooling unit is non-invasive to the filter unit, so that it is not necessary to consider the gap between the filter and the cooling unit. It can be considered that the structure is preferable when the present invention is used because the configuration is such that the filter can be easily replaced and the safety of the mask can be guaranteed and maintained without affecting the mask. It should be noted that the intake / exhaust holes are not always necessary.

Furthermore, as shown in FIG. 7, some variations are conceivable, and in the case of (a), the filter unit can be easily procured by using a normal commercially available mask (7001) as the inner filter without using a dedicated filter. In the case of (b), the body surface can be cooled by equipping the mask with a cooling part (7002) around the mouth, which is an extension of the cooling part using a part with high thermal conductivity such as metal. It is equipped with a cooling component around the mouth as a component, which makes it possible to directly cool the body surface and improve the feeling of coldness when wearing a mask. Furthermore, the above-mentioned cooling parts around the mouth are made into a mesh-shaped panel to secure a gap area for breathing, and the semiconductor cooling parts are directly cooled around the lips using a pipe-shaped refrigerant circulation part. It is also possible.

In order to lower the temperature of the gas inside the mask, which is a factor that inhibits waste heat associated with breathing, it is possible to sufficiently cool by providing a comb-shaped cooling part with a wider contact area, and it is possible to cool the oral cavity and nasal cavity in summer. By avoiding the rise in body temperature due to the mask used for the part, it is possible to take care not to cause health problems such as heat stroke and heat stroke, and depending on the performance of the filter material, a surgical mask level electric electronic cooling mask is realized. , Even in a virus environment such as corona, it can be expected to make people's activities and exercise environment more comfortable, and by making it possible to configure an electric circuit, it is convenient to make remote calls that could not be done in the past. It is possible to realize a mask with high property and safety. Furthermore, by using a solar cell, it is possible to charge the battery at the same time during use outdoors, and by further providing a heat exchange medium circulation unit for liquid cooling on the outside of the electronic heat exchange component, the cooling structure can be duplicated. By using the multiplex structure of, it is also possible to realize high temperature heat exchange efficiency in a dual medium cooling structure such as that used in a nuclear fuel reprocessing furnace. It may also be configured to detoxify the exhaled breath with an electronic disinfectant device for the exhaled breath.
