Purified air 29, which is the purified or sterilized, detoxified, and inactivated air that is taken in, purified by the air purification unit 12 in the infection prevention cylinder 21, and exhausted from the purified air port 23. Is an example of a configuration in which air is sent in front of the face of the person 49 to form an air curtain in front of the face of the person 49, and the person 49 suppresses the intake of unclean air 28.

Further, by providing the air mask 1 having a configuration in which the air is supplied from the neck, the purified air is always stably supplied in front of the face of the person 49, and the purified air 29 is stably supplied. It is possible to send air in front of the face, and it is possible to contribute to the prevention of health or the suppression of deterioration of the person concerned 49, which is useful.
Further, the purified air 29 is supplied to the nose and the vicinity of the mouth so that the person 49 can breathe the purified air in a stable manner. Since the air is blown in the direction as well, it is useful because it is possible to suppress the health damage caused by the exposure of the eyes to viruses, pollen, harmful substances, and the like.

In the example of the configuration of FIG. 1A, the purified air 29 is supplied by the fan 11 in front of the face of the person 49 suspending the air mask 1 from the neck by the neck cord 35 which is the body wearing tool 34. Is an example of a configuration in which the purified air 29 can suppress the inhalation of the unpurified air 28 by creating an air curtain in front of the face of the person 49.

The dynamic rotation port 31 is also an example of a configuration capable of rotating in only one direction to change the direction, but although not shown in the drawing, the rotating rotation neck changes the direction in multiple directions. It is also possible to configure the rotating rotary neck to be possible, and the rotating rotating neck that can change the direction in multiple directions is, for example, two or more rotating rotating necks having a substantially hollow spherical shape. It is a rotary rotary neck provided with a hole, and one or more of the substantially hollow spherical rotary rotary necks provided by rotatably fitting the substantially hollow spherical rotary rotary neck. The hole may be a rotary rotation port 31, and the purified air 29 exhausted from the rotary rotation port 31 may be configured to be capable of supplying air in multiple directions.

The example of the configuration of FIG. 3 is the purification of the configuration as an example of the configuration in which the direction of the air exhausted from the purification air port 23 can be adjusted as in the example of the configuration of FIG. 2 (b) or FIG. 2 (c). This is an example of a configuration in which the bellows port 23 of the bellows structure 27 is provided in the air port 23. By making the purified air port 23 a bellows port 30, not only the opening direction of the purified air port 23 is adjusted, but also the opening direction of the purified air port 23 is adjusted. The purified air port 23 is extended by the bellows structure 27 so that it can be brought closer to the mouth and nose of the person 49, which is useful.
The example of the configuration of FIG. 3 is an example of the configuration of the bellows opening 30 in which the direction-determining tool 25 is movable by the bellows neck, which is the neck of the bellows structure 27.

The example of the configuration of FIG. 3A is an example of a configuration in which the direction of the purified air port 23 is changed by the bellows structure 27 of the bellows port 30, and the purified air 29 exhausted from the purified air port 23 is used. , FIG. 2 (b) or FIG. 2 (c) shows an example of a configuration in which air is supplied in the direction of the mouth and nose of the person 49, which is useful.
The example of the configuration of FIG. 3B is an example of a configuration in which the bellows opening 30 is extended by the bellows structure 27 and arranged close to the mouth and nose of the person 49, and has the configuration. Therefore, the purified air 29 exhausted from the purified air port 23 can be more reliably and more carried to the nose and mouth, which is useful.
The bellows structure 27 in the description of the present invention is formed of a film such as paper, cloth, plastic, rubber, silicon rubber, metal, or a sheet, or a plate-shaped member, and has a repeating structure of mountain folds and valley folds 99. It is a substantially tubular structure.
The example of the configuration of FIG. 4 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. 4A is an example of a configuration in which a person 49 wears an air mask 1 equivalent to that of FIG. 2B and a nose-nose mask 55 which is a mask covering the nose and mouth. The cross-sectional view of the nose mask 55 is shown. 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 between the person's face and the mouth and nose mask 55 is a mask. It is a hollow 58.
The mouth and nose mask 55 may or may not be provided with some kind of sealing member as the sealing portion 57.

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. By doing so, 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 directional 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 exerting 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 the sealing portion 57 is not firmly sealed. However, it was difficult to prevent the invasion of the mask, but by adopting such a configuration, the purified, detoxified, sterilized, and inactivated air is constantly blown into the hollow 58 of the mask. 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 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 it has a configuration in which air 29 can be blown into the hollow mask 58.
Although the mouth-nose mask 55 is a mask that covers both the mouth and the nose in the drawing, it may cover only the mouth or only the nose.

The example of the configuration of FIG. 4 (b) is an example of a front view of the person 49 of the example of the configuration of FIG. 4 (a), 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 shown by the 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 may be brought into close contact with the shape of the face with a wire. It may be good, 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. 4 (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. 4 (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. 4 (d) is an explanatory diagram in which an example of the air flow 17 in the mask hollow 58, which is the same as the example of the configuration of FIG. 4 (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. In an environment where there is not so much wind and there is not much movement of air, or in an environment where there is not so much movement, it 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. 5 is an application 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.
The example of the configuration of FIG. 5A is an example of the person 49 wearing the mask covering the nose and mouth and the air mask 1 in the example of the configuration of FIG. 4A.
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 suppressing 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, silicone 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. 5 (b), the example of the configuration of FIG. 5 (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. 5B, 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, which is useful. If possible, it is desirable that the length of the hanging curtain portion 61 is longer than 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.
Therefore, the weight of the hanging curtain portion 61 itself may be increased or the rigidity may be increased so that the hanging curtain portion 61 does not easily flutter, and a frame such as a wire is provided around or at the end of the hanging curtain portion 61. However, the ribs may be provided, the ribs may be pleated, for example, a part thereof may be bent, or a tape such as an adhesive tape may be provided to increase the rigidity or weight. However, the rigidity may be increased as the foam material, the structure may be such that it can be locked with the air mask 1, and the shape and the shape capable of exhibiting the same action and effect within the scope of the technical idea of the present invention and It can be changed within the range of dimensions and materials.

Further, the hanging curtain portion 61 may be detachably locked to the mouth and nose mask 55, and by making the hanging curtain portion 61 detachable, the hanging curtain portion 61 can be reused. For example, even if the mouth and nose mask 55 is in a disposable form, it can be reused only by the hanging curtain portion 61, so that waste of resources can be reduced and the cost is also reduced. The removable locking structure, which can be reduced and is useful, is not shown in the drawings, but may be a hook-and-loop fastener, a fastener, a hook, a string, etc. It may be a ring, a tape, or the like, 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.
The fastener referred to here is a fastener used for a flexible sheet-like member constituting clothing or the like, which can be freely tightened in the fall as many times as necessary.

In the example of the configuration of FIGS. 5C and 5D, a curtain position holding portion 62, which is a weight for the hanging curtain portion 61 or a rod for increasing the rigidity, is attached to the end of the hanging curtain portion 61. It is an example of the configuration provided, and the example of the configuration of FIG. 5C is an example of the configuration in which a rod is provided as the curtain position holding portion 62 related to the lower end of the hanging curtain portion 61. The example of the configuration of d) is an example of the configuration in which the rods are provided at both ends of the hanging curtain portion 61, and the hanging curtain portion 61 is stable because it is difficult to flutter due to the flow of purified air 17 or the surrounding wind. The curtain position holding portion 62 is a weight or a core material, and the weight or the core material may be a rod, a wire, or a string. A metal such as iron or copper, a plastic material such as polypropylene or polyamide, glass, wood, or bamboo may be used as a core material in which the end of the hanging curtain portion 61 is wound to increase the rigidity. The position may be the edge of the hanging curtain 61 or the mask, the center, the diagonal, the vertical or the horizontal, one or more, and the shape may be. It may be rod-shaped or stud-shaped, 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 hanging curtain portion 61 may be made of the same material as the mouth and nose mask 55, may be provided by locking a different material, may be a non-woven fabric, may be cotton, synthetic fiber, or an effervescent material such as sponge. It may be a flexible sheet, a plastic such as acrylic, polypropylene or polyethylene, rubber, or silicon rubber, and other shapes and dimensions within the scope of the technical idea of the present invention, that is, the same action and effect can be exhibited. , It can be changed within the range of material.

FIG. 6 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. 6A 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. 5B is locked to the air mask 1. be.
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 A6363, 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 A6363 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 A6363 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 configure the structure so that it can follow the movement of the neck, which is useful.

The stretchable winder includes, for example, a spiral spring provided inside a string provided 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 exhibiting the same action and effect.
The mask locking portion A6363 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 A63 or the mask locking portion B64 is , String, rubber, silicone rubber, hook-and-loop fastener, fastener, hook, hook, mating, screw, buckle, ring, hook, etc. It can be changed within the range of the idea, that is, within the range of the shape, size, and material capable of exerting the same action and effect.

In the example of the configuration of FIG. 6B, tube 33-shaped tube 33 necks arranged on both sides of the face are arranged on both sides of the mouth and nose mask 55, and purification is performed from both sides of the mouth and nose mask 55. This is an example of a configuration in which air 29 flows into the hollow mask 58.
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. 6A, 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 can be 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, a 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. 6B, the tube 33 is intubated through the gap between the mouth and nose mask 55, which does not have the sealing 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 the mouth and nose mask 55 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. 6C is an example of the configuration in which the U-shaped purified air guiding portion 54 of the air mask 1 is provided so as to cover the nose, and the purified air is the same as the example of the configuration. Since 29 is configured to reach approximately 100% of the nostrils, it is possible to efficiently supply purified air 29 to the nose and mouth of the person 49. Considering that 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 nostril 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. 7 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 by the double structure formed by the mask overlapping portion 65 and the hanging curtain overlapping portion 66, which is formed by the mask overlapping portion 65 and the hanging curtain overlapping portion 66, overlaps. The hollow portion 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 having more than that.

The example of the configuration of FIG. 7A 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. 7A 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. 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 in which a sufficient amount of purified air 29 can be supplied 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 kept more tightly 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 or may not be used. 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 have a detachable configuration as described in FIG. 5 (b).
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 deviate 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. 7B 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. 7A, 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 below 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. 7 (c), the air mask 1 in the example of the configuration of FIG. 7 (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.

Further, although not shown in the drawing, when the overlapping opening B69 is provided so as to cover the purified air port 23 which is the outlet of the purified air 29 of the air mask 1, the overlapping opening B69 is related. The air mask has a structure in which the size of the opening of the overlapping opening B69 can be adjusted with c or rubber as a mask locking portion so as not to be easily disengaged from the air mask 1. As a configuration for tightening 1, the overlapping opening B69 can be easily attached to the air mask 1, the airtightness is further improved, and the effect of suppressing the invasion of foreign matter, pollen, virus, etc. from the outside air is improved. It is possible, and it is also useful and useful because it can be attached to air masks 1 of various sizes, and the mask locking portion is the relationship between the mouth and nose mask 55 side and the air mask 1. The mask locking portion is a stop portion, and the mask locking portion may be the mask locking portion A63 and the mask locking portion B64 as shown in FIG. By providing a structure or rubber, the purse structure or the air mask 1 covered with rubber is provided so as to cover the overlapping opening B69, which is an adjustable opening that tightens the air mask 1 and locks the air mask 1 so as not to come off from each other. It may have a certain configuration.

The drawstring structure referred to here is provided by passing a string-shaped member in the vicinity of an opening formed by a flexible sheet such as cloth or leather, and the size of the opening can be adjusted by the string-shaped member. It is a configuration with.
The adjustable opening is also a kind of the mask locking portion A63, and is an opening having a configuration in which the size of the opening of the overlapping opening B69 can be adjusted. It is a double opening B69 that can be provided so as to cover the outlet of the purified air 29 so that it can be tightened or substantially adhered to the air. The structure of the adjustable opening in which the size of the opening of the overlapping opening B69 can be adjusted may be a drawstring structure, may be provided with rubber, may be provided with a fastener or a hook-and-loop fastener, or may be provided with a magnet or a magnet. A sheet may be provided, or a configuration including a self-adhesive sheet may be provided. In addition, the structure can be changed within the range in which the characteristic actions and effects of the present invention are exhibited, and the present invention is not limited.

Further, the overlapping opening B69 is hard to be removed from the air mask 1 tightened or adhered to the overlapping opening B69 by the drawstring structure provided in the overlapping opening B69, rubber, a hook-and-loop fastener, a fastener, or the like. The air mask 1 may be configured to be provided with a detachment prevention, and as the detachment prevention, a mask locking portion B64 provided with a convex portion and a concave portion is also useful because it is more difficult to come off.
Further, the mask locking portion A63 and the mask locking portion B64 can be locked by being attracted to or engaged with each other by a magnet, a magnet sheet, a self-adsorption sheet, or a hook-and-loop fastener, so that they are more tightly sealed or hard to come off.

The structure can be provided so as to be along the surface of the tube 33, so that the tip of the tube 33 is locked without facing the direction of the person wearing the mouth and nose mask 55. Therefore, it is difficult for the tip of the tube 33 to hit the person's face, and the purified air supplied from the tube 33 hits the person's face directly. The substantially sheet-like member, which is difficult and more comfortable to attach the mouth and nose mask 55 to which the tube 33 is locked, is useful, and can hold the tube 33 by sandwiching it, is shown in this figure. As in the example of the configuration, the surface locking portion 95 may be used, or the flexible sheet-like member may be locked with the main body covering portion 83 of the mouth and nose mask 55 by hooking the main body. The tube 33 may be sandwiched between the covering portion 83 and the flexible sheet-shaped member.

Further, since the tube attachment / detachment locking portion 94 is the opening / closing locking portion 96, the tube 33 can be easily attached / detached to / from the tube attachment / detachment locking portion 94, which is useful.
