Description

To provide a mask with a comfortable warming cover that can be worn for any length of time since it covers the face at a comfortable temperature and prevents heat buildup inside the mask due to one's own exhaled breath when wearing the mask in high temperatures, causing discomfort due to steaming.
The present invention also relates to a mask with a warm cover that can be used to protect against the cold, since the lower half of the face is covered with a heat insulating material to block cold air even in cold weather.

There are many different types of masks, with many being discussed for their shapes and purposes, but the most common materials for the filter are cloth, gauze, nonwoven fabric, etc. There are general, industrial, and medical masks, and these are selected based on their intended use. Recently, many different types have been released and are being worn to combat the heat, including masks with cooling sprays and ice packs. Masks come in a variety of shapes, including flat, rectangular, pleated, three-dimensional, square, hexagonal, white, plain, patterned, and colored, and are worn by hanging them over the ears using nonwoven fabric, elastic, strings, etc.

Until now, I have never worn a mask during hot weather, but now that I'm wearing a mask that covers my face from my nose and cheeks to my chin, the heat of my breath is trapped and warmed up, making it hard to breathe, uncomfortable, and painful. I wonder if I need a mask now, and I feel like taking it off.

Body temperature is about 36 degrees, while the comfortable temperature is about 23 degrees, so the difference is about 13 degrees. This temperature difference makes you feel hot when wearing a mask. It is said that when you wear a mask, the heat from your breathing is trapped and kept warm, raising your temperature by 4 to 5 degrees. In any case, it is certain that wearing a mask makes you feel hot, stuffy, breathless, uncomfortable, and painful.

If you continue to wear a mask in this condition, some people may experience skin irritation due to sweating.

In addition, when wearing a mask in hot weather, heat is trapped in the face and warms it up, quickly becoming uncomfortable and painful, and even if you endure this, it becomes difficult to breathe.If this is combined with a lack of hydration, the risk of heat stroke suddenly increases, making it dangerous.

I have never worn a mask in hot weather, but the problem is that just wearing one makes my face hot, and my breath traps heat inside the mask, making my face hot and steamy, making me feel uncomfortable, short of breath, and in pain. What kind of mask would be best for me? What would it be like to wear one that covers my face at a comfortable temperature? I would like to consider what kind of mask would be best, something lightweight and simple, and how to protect myself from it.

To solve this problem, when wearing a mask, the inside of the mask from the cheeks to the chin becomes hot and uncomfortable. Therefore, the problem is that heat gets trapped in this area, and when thinking about how to insulate this heat, we need to think about which areas to insulate, what shape to use, and how to select and use the insulating material from the wide variety of masks available.

Needless to say, the target heat source is the heat contained in the breath you breathe. When considering a shape that blocks this heat and insulates, the lower half of the face is covered by the mask and becomes hot and uncomfortable, so the solution is to think about how to insulate this area.

I was thinking about such things every day during the hot weather, when suddenly I realized. The mask I was wearing had shifted down below my nose. The mask covered my mouth to my chin, but I realized that I didn't feel hot even with it on. I realized that I could keep the mask on like this for as long as I wanted. The area I was thinking of was the lower half of my face, that is, from under my nose to my cheeks, mouth, and chin, which was the part that felt hot, and this is the part that needed to be covered and insulated. That way, I could leave the dust removal and sterilization filtration for breathing to the mask itself.

Next, we will use the existing mask and select an insulating material for the inside of the mask to block the heat and insulate it. Materials for insulating include rubber, sponge, and plastic insulating sheets, and recently there has been paper insulating material, so it is fine to select and use these impermeable insulating materials.

The insulating material may be used as it is. However, some insulating materials may not feel good when they come into direct contact with the face. Therefore, a material such as cloth, nonwoven fabric, paper, gauze, or other fabric or sheet that is breathable and comfortable to wear is selected and used as a wrapping material, and the insulating material is wrapped around the face to create an equipment that protects and covers the face from under the nose to the cheeks, mouth, and chin. Since the purpose of wearing the equipment is to cover the face at a comfortable temperature, this is a comfortable temperature cover (hereinafter referred to as comfortable temperature cover), which is a wearable equipment that insulates the lower half of the face by covering it.

There are two ways to wear this warm cover: by hanging the warm cover's nonwoven fabric packaging around your ears with strings or rubber bands, and then wearing the mask on the outside. There is also a standalone method of wearing the warm cover without strings or rubber bands, by placing it on your face, holding it down with the outer mask and wearing it with ear strings or rubber bands.

It was found that wearing a mask on the outside of this warm cover and breathing makes it difficult because the mask expands and contracts. This is because there is no air passage through the mask, and the effective area is halved, resulting in poor airflow. This can be improved by using a porous sponge material ventilation pad (hereinafter referred to as the ventilation pad) for inhalation and exhalation to ensure a breathing passage. Also, if the mask comes into direct contact with the face, it can be protected by sticking nonwoven fabric or wrapping it around the area.

When wearing the warm cover on the face and attaching the mask on the outside, the position under the nose is determined to attach the warm cover, the mask is attached on the outside, the lower part is connected, and the parts on both sides are also connected or joined to combine the warm cover and the mask. Alternatively, a pocket can be provided on the outer mask to hold the warm cover or insulating material. By sandwiching a ventilation pad made of porous sponge material between the two pieces and attaching it, a breathing passage is secured, resulting in a mask part, ventilation part, and warm cover part, which is an integrated warm cover mask (hereinafter referred to as a warm cover mask).

In addition, the mask part is made of a nonwoven fabric or other material that is attached to the outside. The mask part is folded into an N-shape when viewed from the side by repeatedly making mountain and valley folds to fit the mask part covering the lower half of the face from under the nose to the cheeks, mouth, and chin. An insulating material selected from insulating sheet materials or the like is inserted and sandwiched from below into the inside of the upper valley fold that is created inside the mask part. The lower part, both side parts, and the mask part on the front are bonded or joined or otherwise connected to wrap and secure the mask part, resulting in a configuration in which a comfortable warmth cover made of mask fabric is built in and wrapped and secured in a position that covers the lower half of the face with insulating material. The ventilation pad is sandwiched from above into the gap inside the lower valley fold between the mask part on the front and the part wrapping the insulation material, resulting in a modified N-type integrated comfortable warmth cover (hereinafter referred to as an N-type integrated comfortable warmth cover mask). However, the above mask fabric may be a continuous piece of fabric or may be partially connected, or the material may be changed.

In addition, the warm cover makes it difficult to move the mouth and speak. The chin rest (hereafter referred to as the chin rest) is made by wrapping the insulating material in a moon-shaped material that fits the chin area with nonwoven fabric, etc., and attaching it by bonding or joining. Both sides of the chin rest are attached by bonding or connecting them to the inside surface of the warm cover. Next, a mouth pad (hereafter referred to as the mouth pad) is sandwiched between the warm cover and the chin rest using a porous sponge, which allows the wearer to speak by exhaling from the mouth, and the lower part is fastened to prevent it from falling off.

When I put on a mask with a comfortable warm cover and move my body in direct sunlight in summer, I sweat and feel that the parts of the comfortable warm cover that are in contact with my face get wet with sweat. The parts that come in contact with the face are the comfortable warm cover, chin pad, ventilation pad, mouth pad, and the inner part of the one-piece mask with a comfortable warm cover. In order to restore comfort to these parts, the comfortable warm cover, chin pad, ventilation pad, and mouth pad are already available as replacement parts for the comfortable warm cover, and the covers that cover the above parts, such as the comfortable warm cover, ventilation pad, chin pad, mouth pad, and the inner part of the one-piece N-type integrated comfortable warm cover mask, are made of gauze, cloth, nonwoven fabric, etc., and are replacement parts that cover the above parts by covering them according to each part, wrapping them in a bag shape, covering them, pasting them, pasting them together, using rubber, strings, adhesives, Velcro, etc., and are configured to be worn and equipped. There are spare parts for the above comfortable warm cover. This is a replacement part for a heating cover, characterized in that it is configured and used as a replacement cover part for this heating cover.

A small warm cover, the size of which has been reduced to accommodate this warm cover, is placed on the face inside a HEPA filter mask, dust mask, gas mask, etc., and a ventilation base (hereinafter referred to as the ventilation base) made of a porous sponge material with a selected hardness is placed between the masks, etc., and worn in a sandwiched position, forming a base that improves ventilation for breathing, and is composed of a mask part, ventilation part, and warm cover part.

From the above configuration, a three-dimensional mask is used as a base to use a high-level HEPA filter unit, etc., and a rectangular or round HEPA filter unit, etc. is connected and joined to the central front part by considering the frame material and shape together with the mask side of the combined part, adjusting the material and shape of each other, and combining them by gluing, joining, etc. to the joining surface and joining part to form a three-dimensional mask with a HEPA filter. A small comfort cover is attached to the inside of this three-dimensional mask with a HEPA filter. As a base to replace the ventilation pad that is sandwiched between them, the face side has a flat shape that matches the comfort cover, and the outer HEPA unit side is attached in a shape that matches the above-mentioned joining surface, so that a ventilation base (hereinafter referred to as the ventilation base) made of a porous sponge with a hardness that has both ventilation for breathing and the stability of wearing the HEPA unit, etc. is attached. In addition, the outer peripheral surface of this mask is a high-performance HEPA filter comfort cover mask (hereinafter referred to as the HEPA filter comfort cover mask) that is configured to be fitted to the face to be completely sealed and attached to the head, etc. by a fixed band made of strings, rubber, bands, etc. In addition, other dust masks, gas masks, etc. are considered in the same manner as above for their combined parts, and the materials and shapes of each are adjusted and combined by gluing, joining, etc. to the combined surfaces and joints to create a three-dimensional mask. These also have a small warm cover attached to the inside, and the above-mentioned ventilation base is attached between them to create a filter-equipped warm cover mask (hereinafter referred to as filter-equipped warm cover mask).

The material of the three-dimensional mask used in the HEPA filter warm cover mask can be selected by taking advantage of its characteristics such as plastic, paper, nonwoven fabric that can be sterilized, or multiple layers such as one or two layers. It is necessary to rationally combine and join them, and to use materials that maintain the necessary strength and impermeability by reinforcing them, and to select from materials that can be sealed or waterproofed by lamination, coating, surface treatment, application, etc. In addition, the part that comes into contact with the face is selected according to the purpose of the mask, and this is the same for dust masks, gas masks, etc.

The hot breath coming out of the nose would overheat the lower half of the face where the mask was on, making it steamy and making it difficult to breathe, but by wearing this warm cover and a mask with a warm cover, the built-in insulation insulates the hot breath from hitting the face directly, so the heat is no longer felt, and the discomfort and pain caused by heat, steaminess and difficulty in breathing is eliminated. In addition, the warm cover is equipped with nonwoven fabric in the area that comes into contact with the face, so it is kept natural and comfortable and can be worn for any length of time.

By wearing this mask with warm cover when it's hot, you can prevent the temperature of your face from rising, steam it up, and eliminate humidification, preventing rough skin.

By wearing a mask with a warm cover when it is hot, the hot air from your breath is insulated, reducing the rise in temperature and stuffiness, and you are able to maintain a comfortable state without feeling short of breath, uncomfortable, or distressed, thereby reducing the risk of heatstroke.

By selecting and wearing the individual type of this warm cover, you can choose the outer mask body to wear according to your preference, and it has the advantage that you can choose from a wide variety of colors and shapes, as well as be used for general, industrial, medical, etc.

It becomes easy to put on by determining the positions of the two pieces of the mask to be worn on the outside and the warm cover to be worn on the inside, and then combining them by connecting or joining the bottom part and both side parts.

It was found that wearing a mask over this warm cover and breathing makes it difficult because the mask expands and contracts. It has been difficult to breathe while wearing a mask for some time, but it is even more difficult when this warm cover is added. In order to ensure a passage for breathing air, a ventilation pad made of porous sponge is sandwiched between the outer mask and this warm cover, which effectively expands the mask's area and allows the mask's original filtering performance to be used normally, making breathing easier. In addition, adding insulation to this ventilation pad makes it a warm breathable pad, and by wearing the mask in front of this warm breathable pad, it becomes a mask with a breathing passage, ventilation part, and warm cover part, making it an integrated warm breathable pad mask.

To make it easier to talk, the mouth can be moved by using a chin pad wrapped in nonwoven fabric using insulating material to cover the chin area. In addition, a mouth pad made of porous sponge is used to make the voice come out, and it is placed between the warm cover and the chin pad, allowing the breath to come out and making it easier to talk.

Wearing a mask with a warm cover is effective in preventing mouth breathing because it insulates the hot air exhaled with the mouth covered by the warm cover, suppressing temperature rise and stuffiness. However, on the other hand, it can be difficult for people who breathe through their mouths, and it can become a tool to promote nasal breathing.

This warm cover can be used as is in the summer and winter seasons with a mask on the outside. It can also be transformed into a standalone warm cover for use in the winter, even in cold seasons when the cold air is felt, and the warm cover mask can be used as it is, as it insulates the face from the cold air that makes it feel cold.

From the above-mentioned configuration, a high-level HEPA filter unit, etc. is attached to the front part of the three-dimensional mask, etc., and is combined and equipped by connecting, joining, etc. to become a three-dimensional mask with a HEPA filter, which is a three-dimensional mask with a filter. In addition, a dust gas filter unit, a poison gas filter unit, etc. are also similarly connected to the front part of the three-dimensional mask, etc., and are combined and equipped by connecting, joining, etc. to become a three-dimensional mask with a filter, etc.

The compact warm cover is fitted to the face and has a shape that fits inside the above-mentioned filter-equipped three-dimensional mask, and a porous sponge material with a hardness selected to provide ventilation and stability when worn is placed between the mask and the warm cover. By sandwiching a ventilation base that provides ventilation and stability when worn, the lower half of the face is insulated and does not get hot, and the mask is made up of a mask section, a ventilation section, and a warm cover section, making this a warm cover mask with a filter that has an insulating effect.

There are no particular restrictions on the shape of this mask with warm cover, and since the warm cover, ventilation pads, mouth pads, etc. are equipped inside the mask, any mask that can secure a little volume of expansion can be worn comfortably for a long time, which is its original purpose. Moreover, this mask with warm cover has the characteristics of being equipped with natural, versatile, and multifunctional equipment that ensures filtration performance and does not require consumables.

In addition, because the warm cover can effectively utilize the filtration performance without being hindered by the area or performance of the mask itself that is worn on the outside, the desired mask filtration material can be freely selected, making it usable for general, industrial and medical purposes, making this a warm cover mask that is a high-level, high-quality product available in a wide variety of types, from those for exercise to those for professionals with high-performance filtration.

The heat insulating material (6) selected from heat insulating sheets etc. that will become the warm cover (1) is basically rectangular in shape to form the mask (3) that covers the lower half of the face from under the nose to the cheeks, mouth and chin. Because the heat insulating material (6) feels unpleasant when it comes into direct contact with the face, the warm cover (1) is sandwiched between nonwoven fabric (5) and secured around the periphery to fit the three-dimensional shape of the face and cover the lower half of the face.

The method of wearing the comfortable warming cover (1) is to wear it by itself, either by using the nonwoven fabric (5) or ear strings or rubber bands that are the packaging material of the comfortable warming cover (1) to hang it around the ears, and then wear the mask (3) on the outside. There is also a wearing method in which the comfortable warming cover (1) does not have ear strings or rubber bands and is placed on the face, and the ear strings or rubber bands of the outer mask (3) are used to hold the comfortable warming cover (1) against the face and pinch it.

One method is to wear a mask (3) on the outside, place this warm cover (1) on the inside, align it under the nose and place it on the face, and then wear a pleated mask (3) made of square nonwoven fabric (5) on the outside. In this state, the outer mask (3) and this warm cover (1) are connected and combined by determining the positions in three directions of the bottom and both sides, and a breathable pad (2) made of porous sponge material is inserted between them to create a mask with a warm cover (Figure 2).

The reason why the outer mask (3) expands and contracts, making breathing difficult, is because there is no air passage between the outer mask (3) and the warm cover (1). To ensure a passage for breathing through the nose, a ventilation pad (2) made of porous sponge material is used. It is about 10 mm thick and has an area large enough to prevent air from leaking from the outer mask (3). The ventilation pad (2) is placed between the outer mask (3) and the warm cover (1).

This ventilation pad (2) can be made by attaching or wrapping nonwoven fabric (5) or the like to the part that touches the face even without the comfort cover (1). When a mask (3) is worn on the outside, it does not expand or shrink, so it can be worn. However, since there is no insulation material (6), there is heat. Considering the configuration, the insulation material (6) can be wrapped or joined together with the ventilation pad (2) by nonwoven fabric (5) or the like, and by placing the insulation material (6) between the nonwoven fabric (5) or the like and the ventilation pad (2), it becomes a mask with comfort ventilation pad (Figure 30) with the same configuration as the comfort cover (1) and the insulation effect by wearing a mask (3) on the outside.

This is a comfortable warm cover mask with a chin rest (Fig. 12) which is fitted with a chin rest (7) made of insulating material (6) wrapped in nonwoven fabric (5) that fits the shape of the chin so that the wearer can move his/her mouth to talk, and is attached to the inside surface of the comfortable warm cover (1) on both sides. A mouth pad (8) made of porous sponge and measuring approximately 5 cm wide, 2 cm long and 1 cm thick or less is placed between the chin rest (7) and the comfortable warm cover (1) and is placed on top of the chin rest (7).

The one-piece type made of nonwoven fabric or other mask (3) material is a mask made with a normal mask width using the material of the mask (3a) to be worn on the outside, such as nonwoven fabric (5). The mask (3a) part extending downward from under the eyes is repeatedly folded in a mountain fold and valley fold to form an N-shape when viewed from the side, and folded to fit a position that covers the lower half of the face from under the nose to the cheeks, mouth and chin, just like this warm cover (1). Inside the upper valley fold (9) created on the inside, a heat insulating material (6) selected from heat insulating sheet materials or the like is inserted from below, sandwiched and wrapped, and this lower part, both side parts and the mask (3a) part on the front are wrapped and secured together by bonding or joining, etc., to create the mask (3a) part on the front and this warm cover (1) part on the inside. Next, the ventilation pad (2) made of the porous sponge is inserted from above into the inside of the lower valley fold (10) between the front mask (3a) and the warm cover (1) that encases the heat insulating material (6). This results in an integrated N-type integrated warm cover mask (Figure 11) made of mask fabric, which is composed of a mask part, ventilation part, and warm cover part. The mask fabric may or may not be a continuous piece of fabric, and it may be partially connected, and different types may be used by changing the material, etc.

The warming cover (1), the ventilation pad (2), the chin pad (7), and the mouth pad (8) are prepared as spare parts and are made as replacement parts. In addition, the warming cover (1), the ventilation pad (2), the chin pad (7), the mouth pad (8), and the inner surface of the one-piece N-type integrated warming cover mask (Fig. 11), which are the parts that come into contact with the face, are prepared as covers made of gauze, cloth, nonwoven fabric, etc., which are made to fit the above shapes and are attached by pasting them together, wrapping them in a bag shape, applying them, gluing them, tying them together, etc., and are equipped and worn as covers that are placed over the parts that come into contact with the face. The above are spare parts for the warming cover and are replacement parts for the warming cover (24) that are used as replacement cover parts.

When this warm cover (1) is used for a dust mask, gas mask, etc., it has a similar shape and configuration to the warm cover mask with HEPA filter (Fig. 17), and the HEPA filter unit (15) is connected to the front part of the three-dimensional mask, etc., and combined by joining, etc. to form a three-dimensional mask with a HEPA filter unit (16). Dust masks, gas masks, etc. are also connected to the front part of the three-dimensional mask, etc., and combined by joining, etc. to form a three-dimensional mask with a filter (16). Also, it is a small comfortable cover (23) that can be worn in a small shape that can fit inside the filter-equipped three-dimensional mask (16) etc., including generally existing dust masks and gas masks, etc., and this is worn on the face, and the strength is selected by inserting a porous sponge material between the filter-equipped three-dimensional mask (16) such as the above-mentioned dust mask, gas mask, etc., and the HEPA filter-equipped comfortable cover mask (Figure 17), etc., to form a ventilation base (14) that supports the above-mentioned mask and provides both ventilation for breathing and stability when worn, and this is the filter-equipped comfortable cover mask that is worn by inserting and clamping it, and is worn on the head etc. with a fixing band (13) etc.

A square nonwoven pleated mask (3) was used on the outside, and the heat insulating material (6) that became the warm cover (1) was a rectangular hard vinyl sheet folded in half, and the nonwoven fabric (5) of another mask was folded in half and sandwiched between them to form the warm cover (1).

When I tried wearing it, I found that the three-dimensional shape of my face and the shape of the warm cover (1) did not fit my face well, so I shifted the vinyl sheet, which is the insulating material (6) inside the warm cover (1), slightly into an X-shape and folded it twice to make it thicker and more bulging, and then sandwiched it again in the nonwoven fabric (5). I folded it back again and made several corrections to make it fit the mask (3) better, and cut the insulating material (6) sandwiched inside from a rectangle to fit the chin on both sides, so that it resembled a horizontal pentagon, so that the lateral direction from under the nose to the cheeks would fit smoothly. I glued three sides to wrap it in nonwoven fabric (5). The warm cover (1) was completed, and it was able to fit and wear well on the face. The deformation diagrams of the warm cover (1) (Figures 6 to 9) that serve as references at this time are of a shape that covers from under the nose to the chin. In addition, if the insulating material (6) had been selected appropriately, it may have been easier to fit the face and wear it.

The warm cover (1) is placed on the face, with the upper part aligned under the nose, and the mask (3) is attached to the outside. At this position, the center of both lower parts is sewn horizontally with thread for about 3 cm, and the warm cover (1) is joined by connecting in three directions, including both sides. At this time, it is important that the warm cover (1) is positioned so that it is in contact with the cheeks. Alternatively, a pocket can be provided in the outer mask (3) to hold the warm cover (1) or insulating material (6). By sandwiching the above-mentioned ventilation pad (2) in the gap between these two pieces and wearing it, an integrated warm cover mask (Figure 2) is created that also ensures a breathing passage.

Considering a one-piece mask made from the material of the mask (3) instead of the above combined type, the material of the mask (3a) to be worn on the outside is extended from under the eyes downwards by repeatedly folding in mountain and valley folds into an N-shape, and the insulation material (6) is inserted from below into the inside of the upper valley fold (9) on the inside of the mask (3a) material in a position that covers the lower half of the face from under the nose to the cheeks, mouth, and chin, and the insulation material (6) is inserted and sandwiched from below, and wrapped around the lower part, the side part, and the mask part on the front are slightly inflated and joined together to cover the lower half of the face. A single piece of mask fabric is used to build in the comfortable warm cover (1). Next, the ventilation pad (2) is sandwiched from above into the gap inside the lower valley fold (10) that wraps the front mask part (3a) and the insulation material (6), and the mask is completed. This resulted in the creation of an N-type integrated mask with warm cover (Figure 11), characterized by a configuration in which the mask section, ventilation pad section, and warm cover section are arranged in that order.

My impression of wearing this warm mask (Fig. 2) is that my face doesn't get hot, so I feel like I can wear it for as long as I want without getting stuffy. However, when I breathe, the mask (3) expands and then contracts. When I exhale, it expands, and when I inhale, it contracts, creating resistance, which is a problem. Since there is no passage for the air to breathe, and the flow is poor, I solved this by inserting a rectangular porous sponge ventilation pad (2) about 10 mm thick between the warm mask (1) and the outer mask (3) to ensure ventilation. If it had a slightly nice smell, it would be a perfect warm mask (Fig. 2).

In addition, when considering the structure of the ventilation pad (2), either the insulation material (6) can be wrapped around the ventilation pad (2) by the nonwoven fabric (5) or joined to it, and either is effective. By inserting the insulation material (6) between the nonwoven fabric (5) or the ventilation pad (2), the structure is the same as that of the comfort cover (1), and the ventilation pad (2) makes the area of the mask (3) worn on the outside more effective, making breathing easier, and creating a comfortable and insulating mask with ventilation pad (Figure 30).

When wearing the mask with warm cover (Fig. 2), I noticed that it was difficult to talk because the mouth was covered by the warm cover (1). In the shape of the chin, a chin pad (7) containing heat insulating material (6) wrapped in nonwoven fabric (5) like the warm cover (1) was added to this area. Both sides were sewn to the inside of the warm cover (1) with thread, making it easier to move the jaw. A mouth pad (8) made of porous sponge was placed between the chin pad (7) and the warm cover (1), so that breath would not leak out when speaking, making it easier to talk (Fig. 12).

Even in cold seasons, this mask with warm cover (Fig. 2) can be used for winter use because the warm cover (1) insulates the cold air from under the nose to the chin, which is the part of the face that feels cold. For protection against the cold, the fabric of the outer mask (3) can be changed, insulation material (6) that covers the nose area can be added, the lower part of the chin can be enlarged, etc. Although the configuration is the same, by slightly changing these equipment, it can be made into a mask with warm cover (Fig. 2) for protection against the cold that keeps the lower half of the face warmer as a winter mask.

I thought I was done after putting on this mask with warm cover (Fig. 2), but when I walk, run, exercise, and move my body in direct sunlight in summer, I sweat and feel that the parts of the mask that come into contact with my face, such as the warm cover (1), get wet with sweat, which makes me uncomfortable. Even if you do not replace the mask with warm cover (Fig. 2), you can use the warm cover (1), ventilation pad (2), chin pad (7), and mouth pad (8) as spare parts that get wet with sweat as replacement parts. In addition, the parts that come into contact with the face, such as the warm cover (1), ventilation pad (2), chin pad (7), and mouth pad (8), and the inner surface of the one-piece N-type one-piece warm cover mask (Fig. 11), are covered with a cover made of gauze, cloth, nonwoven fabric, etc. that matches the shape of each of the above parts, wrapped in a bag shape, placed, glued together, or covered with strings, etc., to create a new cover that can be worn as an accessory to replace. It would be convenient to have spare parts for these covers, or replacement parts for the warm cover (24) to use as replacement parts.

The above configuration led to the idea of a HEPA filter-equipped warm cover mask (Fig. 17). A high-level HEPA filter unit (15) and other components are combined in front of the three-dimensional mask (16) to form a HEPA filter-equipped three-dimensional mask (22). A small warm cover (23) is attached to the inside of the mask, and a ventilation base (14) made of porous sponge is sandwiched between the mask and the ventilation base (14) for ventilation and stability. This results in a high-performance HEPA filter-equipped warm cover mask (Fig. 17) with a mask part that insulates the lower half of the face, a ventilation part, and a warm cover part.

The structure is the same as the above HEPA filter-equipped warm cover mask (Fig. 17), and when using a dust mask or gas mask, the above dust gas filter unit (21) or gas gas filter unit (21) is connected, joined, or otherwise combined with the front part of the three-dimensional mask, etc., to form a filter-equipped three-dimensional mask (16), etc. A small warm cover (23) is attached to the inner surface, and the ventilation base (14) made of porous sponge is sandwiched between them to provide ventilation for breathing and stability when worn, resulting in a mask part, ventilation part, and warm cover part, and a filter-equipped warm cover mask (Fig. 18) has been created by adding a modification to insulate the lower half of the face to existing high-performance dust masks and gas masks, etc.
