This is an example of a configuration in which the photocatalyst of the catalyst material 38 is activated by the light from the light source 20 to activate the sterilization and decomposition effects.
The star mark indicates the light source 20.
Since the light source 20 has a configuration provided inside the infection prevention cylinder 21, it is possible to generate ultraviolet rays that are too strong for 49 humans without affecting 49 humans. In addition to the sterilizing, detoxifying, and inactivating effects of the photocatalyst, it is possible to exert the sterilizing, detoxifying, and inactivating effects by ultraviolet rays, which is useful.
The example of the configuration of FIG. 8 (d) is an example of the configuration in which the example of the configuration of FIG. 8 (a) secures the length of the air flow path 19 by providing the hairpin curve 37 in the vertical direction.

By slowing down the air flow 17 near the purification port 24, it is possible to purify, sterilize, and detoxify the unpurified air 28, and it is possible to provide an air purification unit 12 having a sufficient volume or area. It is useful.

The example of the configuration of FIG. 9 is an example of the configuration of the air purification unit 12, and shows an example of the configuration of a heater in which the air purification unit 12 is a filter and a heating unit 15 for heating the filter.

The example of the configuration of FIG. 9A is an example of a configuration in which the outside of the heating filter 53 is wound with a band heater which is a heat source of the heating unit 15.
The heating filter 53 is an example of a configuration in which a hole is provided in a metal such as ceramic or iron, and when air passes through the hole, heat is applied from the heated filter to obtain the heat or the heat. This is an example of a configuration in which the air is purified, sterilized, and detoxified by radiant heat such as far infrared rays. If the height of the heating filter 53, the size of the outer shape, or the size of the hole is too large for ventilation, it becomes a ventilation resistance, obstructs the flow of air, and if the size of the hole of the heating filter 53 is too large, It becomes difficult to transfer heat to the air and viruses that pass through the filter, and if it is too small, it becomes ventilation resistance, so it is necessary to provide more holes, and the heat conduction of the heating filter 53. The appropriate configuration should be determined based on the relationship between the properties and the arrangement of the heaters.
Further, the longer the height of the filter, the more effective the sterilization of viruses and the like.

The example of the configuration of FIG. 9B is a configuration in which the holes of the two heating filters 53 are staggered, and a gap is provided between the two heating filters 53. By staggering the positions of the holes in this way, the virus or the like passing through the heating filter 53 will turbulently flow while colliding with the wall of the heating filter 53, which is the path of the air. This is an example of a configuration in which a virus or the like is sterilized, inactivated, or detoxified by transferring heat to the passing air evenly and the probability of hitting the heating filter 53 having high heat.

Although omitted in the figure of FIG. 9B, the two heating filters 53 are arranged side by side so as to be wound on the outside in a tubular shape or provided in the infection prevention cylinder 21. Is.
Further, by arranging the heating filters 53 at intervals, the air in the space between the heating filters 53 and the heating filters 53 is also in a heated state, and the air flow 17 is also turbulent. , The effect of killing the virus can be improved, and in the example of the configuration shown in FIG. 9B, only two of the heating filters 53 are arranged side by side. However, it may be more than that, and the larger the number, the higher the probability that the virus can be removed, which is useful.

In the example of the configuration of FIG. 9 (c), in the configuration in which the two heating filters 53 of the configuration of FIG. 9 (b) are arranged side by side, the three heating filters 53 are vertically arranged on a skewer with a rod-shaped cartridge heater. Is an example of.
With such a configuration, the heat generated by the heater can be more efficiently used in the heating filter 53 or the space between the heating heater and the heating heater, and the heater can be used. It serves as a pillar that supports the heating filter 53, and can hold the filter more stably, which is useful.

The example of the configuration of FIG. 9D is an example of a configuration in which two heating filters 53 are arranged side by side, and a rod-shaped cartridge filter which is a heat source of the heating unit 15 is sandwiched between the two heating filters 53. is there. With such a configuration, it is possible to heat the heating filter 53 more entirely, which is useful.
Further, the heater for heating the heating filter 53 in the example of the configuration of each figure of FIG. 9 may be a band heater, a rod-shaped cartridge heater, a net-shaped heater, and other technical ideas of the present invention. It can be changed within a range, that is, within a range of shapes or dimensions capable of exerting the same effect.
Further, in the configuration of the heating filter 53, a photocatalyst filter may be used instead of the heating filter 53, and a light source 20 or an ultraviolet light source 20 may be used instead of the heating unit 15.
Further, the power source of the heater or fan 11 by electricity may be a 100 V power source, USB, or a battery type, or a battery rechargeable by sunlight may be used, but a more stable and high temperature heating filter may be used. As the configuration of 53, it is desirable to configure the power supply via an outlet such as 100V, but in consideration of the performance of the battery, the necessary heater, the temperature, the usage time, and other necessary conditions. It is selectable.

The example of the configuration of FIG. 10 is an example of the configuration of the mask unit 2 in which the air mask 1 and the mask covering the nose and mouth are combined.

An example of the configuration of FIG. 10 (a) is an example of a configuration in which a person 49 wears an air mask 1 equivalent to that of FIG. 2 (b) and a nose mask 55 which is a mask covering the nose and mouth. The cross-sectional view of the nose mask 55 is shown, and the nose mask 55 covering the nose and the mouth is a portion where the upper part of the nose mask 55 is substantially in close contact with the face of the person 49 from the nose in an inverted U shape. An example of a configuration in which a seal portion 57 is provided and the lower portion of the mouth and nose mask 55 is provided with a mask opening 56 which is an opening, and a hollow space surrounded by the seal portion 57 and the mouth and nose mask 55 is a mask. It is a hollow 58.

The mask hollow 58 may be narrow or wide, but the size of the mask hollow 58 may be appropriately set in consideration of the supply capacity of the purified air 29 by the air mask 1. Desirably, for example, if the supply capacity of the purified air 29 is sufficiently large with respect to the human breathing volume and the circumference of the mouth and nose mask 55 is sufficiently filled with the purified air 29, the mask is concerned. The hollow 58 may be narrow, or may be configured not to have the mask opening 56. If the supply capacity of the purified air 29 is not so large, the mask hollow 58 and other figures will be described. As shown, the configuration is a combination of the direction-determining tool 25, the direction-determining foot 26, the rotating rotating neck, the bellows neck, the purified air guiding portion 54, the hanging curtain portion 61, the emission suppression plate 13, and the like. It is desirable that the purified air 29 can be efficiently sucked by the person 49 by the structure for supplying the purified air 29 without waste and the structure for ensuring an appropriate amount of stored air.

In addition, the direction-determining tool 25 can be changed within the range of the technical idea of the present invention, that is, within the range of the shape or size capable of exhibiting the same action and effect.

The air mask 1 suspended from the neck blows purified air 29, which is purified air in the direction of the mouth of the person 49, and the flow 17 of the purified air 29 enters the mask hollow 58 through the mask opening 56. The person 49 is an example of a configuration in which the air stored in the mask hollow 58 and the air entering the mask hollow 58 from the mask opening 56 are sucked. If only a so-called general mask that covers the mouth is used, the filtering function of the mask itself can filter even fine particles, and if the sealing portion 57 is not firmly sealed, the virus caused by the mask. It was difficult to prevent the invasion of the mask, but by adopting such a configuration, by constantly blowing purified, detoxified, sterilized, and inactivated air into the mask hollow 58, It is possible to prevent the inhalation of such foreign substances, viruses, pollen, gas, etc., which is a useful configuration.

The mouth and nose mask 55 may be a non-woven fabric, cotton, synthetic fiber, a flexible sheet such as a foamable resin such as a sponge, a plastic plate such as acrylic or polypropylene, rubber, or silicon. It may be made of rubber, and can be changed within the range of the technical idea of the present invention, that is, within the range of the shape, size, and material capable of exhibiting the same action and effect.
Further, the purification air port 23, which is the opening of the air mask 1, is configured to have a bellows structure 27 as shown in the example of the configuration of FIG. 3, thereby purifying from a position closer to the mask opening 56. It is useful because the air 29 can be blown into the hollow mask 58.
In the drawing, the mouth-nose mask 55 is a mask that covers both the mouth and the nose, but it may cover only the mouth or only the nose.

The example of the configuration of FIG. 10B is an example of a front view of the person 49 of the example of the configuration of FIG. 10A, and the purified air 29 blown from the air mask 1 is the mouth and nose mask. This is an example of a configuration that falls into 55.
The portion of the mouth and nose mask 55 indicated by an inverted U-shaped dot pattern from the nose of the person 49 indicates the seal portion 57 of the mouth and nose mask 55, and the stored air is the seal portion. From 57, it is an example of a configuration that is substantially difficult to leak, and the sealing portion 57 may be provided with an effervescent material such as a sponge, or may be made of rubber, silicone rubber, or adhered to the shape of the face with a wire. It may be an adhesive tape, or it may be an adhesive tape, and it can be changed within the range of the technical idea of the present invention, that is, within the range of the shape, size, and material capable of exhibiting the same action and effect.
The example of the configuration of FIG. 10 (c) shows an example of the configuration in which a part of the purified air 29 from the air mask 1 in the example of the configuration of FIG. 10 (a) blows through in front of the mouth and nose mask 55. With this configuration, the air that flows from the air mask 1 to the vicinity of the front of the mouth and nose mask 55, that is, unpurified air that may contain a virus or the like, flows out of the mouth and nose mask 55. It is an example of a configuration in which the person 49 is prevented from sucking the unpurified air by blowing it off with the air from No. 1, which is useful.

Further, by flowing the purified air 29 in front of the mouth and nose mask 55, it becomes possible to reduce the adhesion of viruses, pollen and other foreign substances to the surface of the mouth and nose mask 55, and the mouth and nose mask 55 At the time of putting on and taking off, it is possible to prevent the virus or the like attached to the surface of the mouth and nose mask 55 from adhering to the hand and causing harm to the health by the virus adhering to the hand, which is useful.

The description of the example of the configuration of FIG. 10 (d) is an explanatory diagram in which an example of the air flow 17 in the mask hollow 58 equivalent to the example of the configuration of FIG. 10 (a) is described in more detail.

The purified air 29 blown from the air mask 1 and the exhaled air exhausted from the person 49 exist as stored air in the mask hollow 58, and the air that cannot fit in the mask hollow 58 is the return air 59. The return air 59 is discharged from the mask opening 56, and the return air 59 floats as a retention air 60 near the outside of the mask opening 56 to push away viruses, foreign substances, gas, etc. near the mask opening 56, thereby causing the area. It is useful because it has the effect of considerably diluting the concentration of viruses, foreign substances, gas, etc.
It should be noted that the purified air 29 is continuously supplied from the air mask 1 into the hollow 58 of the mask, so that the person 49 can breathe with substantially purified air, which is useful.
It should be noted that the lump of the stagnant air 60 is immediately diffused to the surroundings when the person 49 is walking or moving, or when the wind is strong, and the person 49 is to the last. In an environment where there is not much wind and there is not much movement of air, or in an environment where there is not much movement, the mask stays in the vicinity of the mask opening 56.
The retention area of the retention air 60 is an area indicated by an elliptical broken line area on the drawing.

The example of the configuration of FIG. 11 is an application example of the configuration of the mask unit 2 including the air mask 1 and the mask covering the nose and mouth.

An example of the configuration of FIG. 11 (a) is an example of a person 49 wearing a mask covering the nose and mouth in the example of the configuration of FIG. 10 (a) and an air mask 1 in the example of the configuration of FIG. 7 (a). ..
Since the air mask 1 is provided with the emission suppression plate 13, the purified air 29 blown from the air mask 1 is difficult to diffuse, does not mix much with the surrounding air, and is affected by the surrounding wind and the like. This is an example of a configuration in which the purified air 29 from the air mask 1 is more efficiently blown into the mouth-nose mask 55 or the mask hollow 58, which is useful.
Further, by providing the emission suppression plate 13, the retained air 60 is also difficult to diffuse, is difficult to mix with the surrounding air, and is useful because it has a configuration in which it can breathe with more purified air.

The emission suppression plate 13 may be in the form of a plate, may be a flexible sheet, and may be made of a metal such as iron or copper, a plastic material such as polypropylene or polyamide, glass, wood, bamboo, or the like. It may be cotton, linen, vinyl, rubber, silicon rubber, or other changes within the scope of the technical idea of the present invention, that is, within the range of shapes, dimensions, and materials that can exhibit the same effects. Is something that can be done.

As for the example of the configuration of FIG. 11 (b), the example of the configuration of FIG. 11 (a) is an example of the configuration in which the diffusion of the purified air 29 from the air mask 1 is suppressed by the emission suppression plate 13. In the example of the configuration of FIG. 11B, a part of the mask covering the nose and the mouth is provided with a hanging curtain portion 61 which is a part hanging in a curtain shape under the air mask 1. This is an example of a configuration in which air is supplied into the hollow 58 of the mask while suppressing the diffusion of the purified air 29, which is useful.

Since the hanging curtain portion 61 has a long configuration up to the purified air port 23 which is the opening of the air mask 1, the purified air 29 or the retained air 60 exhausted from the purified air port 23 is not easily dispersed and is useful. If possible, it is desirable that the length of the hanging curtain portion 61 is longer than that of the jaw of the person 49 and hangs down to the purification air opening 23.
Further, the hanging curtain portion 61 is weighted with respect to the amount and speed of the purified air 29 blown from the purified air port 23, or with respect to an assumed external factor such as the strength of the surrounding wind. If it is too light, it will flutter at the wind speed and the like, and the effect of firmly blocking the surrounding air with the stagnant air 60 or the purified air 29 will be diminished.

FIG. 12 is an example of a variation of the configuration of the air mask 1 and the mouth and nose mask 55.

The example of the configuration of FIG. 12A is an example of the configuration in which a part of the mouth and nose mask 55 or a part of the hanging curtain portion 61 in the example of the configuration of FIG. 11B is locked to the air mask 1. is there.
By locking the air mask 1 with a part of the hanging curtain portion 61 or the mouth and nose mask 55 to each other as in the example of the configuration, the positional relationship between the air mask 1 and the hanging curtain portion 61 or the mouth and nose mask 55 is more stable. The purified air 29 from the air mask 1 can be masked more stably by reducing the gap between the air mask 1 and the hanging curtain portion 61 or the mouth and nose mask 55. It is useful because it can be delivered into the hollow 58, it can be configured to suppress the diffusion of the retained air 60, and it is possible to breathe with more purified air.
The locked portion is a mask locking portion, and the locking portion on the mouth and nose mask 55 side is the mask locking portion A63, and the locking portion on the air mask 1 side is the mask locking portion B64, respectively. In the example of the configuration of (a), the mask locking portion A63 is a ring-shaped string, and the mask locking portion B64 is an example of a configuration in which a locking portion which is a mooring columnar hook is provided. This is an example of a configuration in which the string-shaped mask locking portion A63 is hooked on and locked to the mooring columnar mask locking portion B64.

However, if there is not enough length in the mask locking portion or the hanging curtain portion 61, for example, when the person 49 makes a facial movement such as turning around or nodding, the mask is pulled by the mask locking portion and the mask is masked. Since a problem such as misalignment occurs, the length of the mask locking portion, the length of the hanging curtain portion 61, or the like may be relaxed, or the hanging curtain portion 61 may be loosened. The material is made of a stretchable material, or the mask locking portion is provided with a winder that allows the string to be stretchable by winding the string, for example, a reel key holder or a rubber-like material. By providing a mask locking portion having a stretchable structure, it is possible to have a configuration that can follow the movement of the neck, which is useful.

The stretchable winder is provided with, for example, a spiral spring provided inside a string wound around the winder, and the string wound around the string is expanded and contracted by the force of the spring. It is a winder that can be freely taken in and out, and can be changed within the range of the technical idea of the present invention, that is, within the range of the shape, size, and material capable of exerting the same action and effect.
The mask locking portion A63 is a locking portion between the mask covering the mouth or nose of the person 49 and the mask locking portion B64 provided on the air mask 1, and the mask locking portion A or the mask locking portion B64 is , Strings, rubber, silicone rubber, hook-and-loop fasteners, hooks, hooks, mating, screws, buckles, rings, hooks, and other technical ideas of the present invention. It can be changed within a range, that is, within a range of shapes, dimensions, and materials capable of exerting the same action and effect.

In the example of the configuration of FIG. 12B, tube 33-shaped tube 33 necks arranged on both sides of the face as shown in FIG. 4 are arranged on both sides of the mouth and nose mask 55, and the mouth and nose mask is concerned. This is an example of a configuration in which purified air 29 flows into the mask hollow 58 from both sides of 55.
With such a configuration, for example, when the air mask 1 is suspended from the neck to the front of the chest as in the example of the configuration of FIG. 12 (a), the air mask 1 is an obstacle to perform some work. In such a case, by attaching the air mask 1 to the back or the back of the neck or the head, it does not interfere with work or the like and is useful, and the flexibility of the tube 33 or the air mask 1 is used. By wearing it closer to the head, the position of the purification port with respect to the mouth and nose mask 55 can be arranged more stably, so that the purification air 29 can be breathed more stably, which is useful. Is.

By directly intubating the tube 33 into the mask hollow 58 in the mouth and nose mask 55 to supply purified air 29, the inside of the mask hollow 58 becomes a positive pressure, and the pressure is increased. It is a configuration that can expel foreign substances such as viruses and pollen that have entered the mask hollow 58, and is a highly useful configuration.

Further, although not shown in the drawing, even if the mouth and nose mask 55 is provided with a tube 33 locking portion which is a locking portion for locking the tube 33 and holding the position of the tube 33. The position of the tube 33 can be held and is useful, and the tube 33 locking portion may be a string, rubber, a ring, a hook, a hole, and the like, within the scope of the technical idea of the present invention. That is, it can be changed within the range of the shape, size, and material capable of exerting the same action and effect.

Further, in the example of the configuration of FIG. 12B, the tube 33 is intubated through the gap between the mouth and nose mask 55 without the seal portion 57 of the mouth and nose mask 55 and the face. The tube may be infused from the portion provided with the seal portion 57, or the mouth and nose mask 55 may be configured to have the seal portion 57 all around the four sides, or may be provided through a hole provided in the mouth and nose mask 55. The tube 33 may be inserted.

The example of the configuration of FIG. 12 (c) is an example of the configuration in which the U-shaped purified air guiding portion 54 of the air mask 1 of the example of the configuration of FIG. 6 (b) is provided so as to cover the nose. As in the example of the configuration, the purified air 29 reaches the nose hole approximately 100%, so that the purified air 29 can be efficiently sent to the nose and mouth of the person 49. Further, in particular, considering that, basically, many people 49 are breathing through the nose, it is useful because the purified air 29 can be pinpointed to the nose.
Further, as a configuration for supplying purified air 29 to the nose, for example, in an inpatient or the like, there is a system in which a tube is inserted into the nose hole to supply air such as oxygen. Such a configuration intubated into the nose is not very realistic in terms of appearance and practical use in daily life, and from this point of view, such a configuration is useful.
Further, if a general mask is attached so as to cover the purified air guiding portion 54, the purified air 29 will be sent into the mask, so that a fine mask is used. Even if it is not present, it is useful because it is possible to suppress the invasion of viruses, pollen and other foreign substances from the outside air by setting the pressure inside the mask to positive pressure.

An example of the configuration of FIG. 13 is an example of a configuration in which the mouth and nose mask 55 or the hanging curtain portion 61 includes a mask overlapping portion 65 or a hanging curtain overlapping portion 66 having a double structure.
The hollow space sandwiched between the mask overlapping portion 65 and the mask overlapping portion 65 formed by the double structure of the hanging curtain overlapping portion 66 and the double structure formed by the hanging curtain overlapping portion 66 is a overlapping hollow space. Part 67.
The mask overlapping portion 65 is a overlapping hollow portion 67 which is a portion of the double structure of the mouth and nose mask 55 main body, and the hanging curtain overlapping portion 66 is a overlapping hollow portion which is a portion of the double structure of the hanging curtain portion 61. 67.
Further, the mask overlapping portion 65 or the hanging curtain overlapping portion 66 may have a double structure, a triple structure, or a multiple structure more than that.

The example of the configuration of FIG. 13A is a cross-sectional view of an example of the configuration including the hanging curtain overlapping portion 66 in which the hanging curtain portion 61 provided in the mouth and nose mask 55 is doubly overlapped.
In the overlapping hollow portion 67, one opening is provided in the mask hollow 58, the opening on the mask hollow 58 side of the overlapping hollow portion 67 is the overlapping opening A68, and the overlapping hollow portion 67 is on the outside air side. The opening on the outside air side of the overlapping hollow portion 67 is the overlapping opening B69, and the overlapping hollow portion 67 includes the overlapping opening A68 and the overlapping opening B69.

The person concerned in the example of the configuration of FIG. 13A wears the same air mask 1 as in FIG. 2C, wears the mouth and nose mask 55, and the overlapping opening B69 of the mouth and nose mask 55 is the air mask. Purified air 29 exhausted from the rotating rotation port 31 is supplied from the overlapping opening B69 side into the overlapping hollow portion 67, and is provided from the overlapping opening A68 so as to cover the rotating rotation port 31 of 1. This is an example of a configuration in which air is sent into the mask hollow 58 and the person concerned can breathe in the purified air 29. The purified air 29 exhausted from the air mask 1 is placed in the mask hollow 58 which is approximately 100%. It is possible to supply air, and the overlapping hollow portion 67 can secure a flow path of air having a sufficient thickness, and is useful because it has a configuration capable of supplying a sufficient amount of purified air 29 with a margin.

It should be noted that the portion of the overlapping opening A68 that is in contact with the human face is useful because it can be more sealed with the outside air by forming the seal portion 57. Since the pressure is positive due to the air supply from the air mask 1, the portion of the overlapping opening A68 that is in contact with the human face may not necessarily be the seal portion 57, but the presence or absence of the seal portion 57 may be present. As for the configuration, an appropriate configuration should be selected depending on the amount of air supplied, the assumed usage environment in which the mouth and nose mask 55 is attached, and the like.
The hanging curtain portion 61 may be detachable as in the description of FIG. 11B.
Further, by locking the bellows opening 30 with the mask locking portion to the rotating port which is also the purification air port 23 with the overlapping opening B69, the overlapping opening B69 does not shift from the purification air port 23 and is always stable. Purified air 29 can be supplied from the overlapping opening B69, which is useful.

The example of the configuration of FIG. 13B is an example of the configuration in which the overlapping opening A68 is provided substantially in the middle of the main body of the mouth and nose mask 55.
As the usefulness of such a configuration, there are improvement points of the following problems. For example, in the example of the configuration of FIG. 13A, the overlapping opening A68 is a configuration that opens directly under the nose and mouth of the person concerned. There is also a problem that saliva such as sneezing discharged from the mouth easily falls on the air mask 1, and the position of the overlapping opening A68 is raised, for example, the position of the mouth and nose mask 55. By not forming a large opening directly under the mouth and nose, it is possible to prevent the air mask 1 from being directly soiled even if saliva or the like due to such sneezing falls directly below due to gravity, which is useful.

In the example of the configuration of FIG. 13 (c), the air mask 1 in the example of the configuration of FIG. 13 (b) is an example of the configuration of the bellows mouth 30 in the example of the configuration of FIG.
With this configuration, the bellows opening 30 can be extended and placed closer to the human face, so that the length of the hanging curtain portion 61 can be shortened, or the drawing can be made. Although not shown in the above, by locking the bellows opening 30 with the overlapping opening B69 with the mask locking portion, the position of the bellows opening 30 can be followed even if the face of the person concerned moves. It is a useful configuration that can flexibly respond to the movement of the human face.

The example of the configuration of FIG. 13D is an example of the configuration in which the purification port of the air mask 1 is provided on the tube 33.
Further, the overlapping hollow portion 67 is a overlapping hollow portion 67 of the main body portion of the mouth and nose mask 55, and the tube 33 is intubated from the overlapping opening B69 of the overlapping hollow portion 67, and the overlapping hollow portion 67 is involved in the overlapping hollow portion 67. This is an example of a configuration in which a purification air port 23 provided at the tip of the tube 33 is arranged.
Since the tube 33 is intubated into the overlapping hollow portion 67, saliva such as sneezing of a person does not directly adhere to the tube 33, and the tube 33 can be prevented from becoming dirty. Therefore, even when the tube 33 is repeatedly used, it is possible and useful to use the tube 33 which is more clean.
Further, by arranging the position of the overlapping opening A68 of the overlapping hollow portion 67 on the upper side of the mouth and nose mask 55, that is, on the upper side of the nose as in the example of the configuration of FIG. 13C. Even if the purification air port 23 provided at the tip of the tube 33 is taken out from the overlapping opening A68, the tube 33 is not easily soiled by the sneezing of the person concerned and is useful.
Further, since the tube 33 is also sandwiched by the overlapping hollow portion 67 in a wide portion, it has a configuration that can be stably held, which is useful.

Further, although the overlapping openings B69 are examples of configurations provided on the lower side of the mouth and nose mask 55, they may be provided on the side or on the upper side.

The side of the overlapping hollow portion 67 in contact with the face of the person concerned is an example of the configuration of the sealing portion 57, and the overlapping opening A68 is related to the outside of the overlapping opening A68 from the contacting portion with the person concerned. The structure is such that it is difficult for outside air to enter the inside of the mask hollow 58, which is useful. However, since the inside of the mask hollow 58 is positively pressured by the air supplied from the air mask 1, the outside air is released. The structure is difficult to enter, and the presence or absence of the seal portion 57 should be selectively determined depending on the air supply capacity of the air mask 1, the surrounding environment such as outside air, and the target pollution.

The mouth and nose mask 55 of the example of the configuration of FIG. 14 (b) is a front view of only the mouth and nose mask 55 equivalent to the configuration of FIG. 14 (a).
