The air may contain viruses such as influenza virus, pollen, toxic gas, foul odors, harmful substances, etc. from the unpurified air inlet 24, which is an air intake port in the atmosphere provided at the bottom of the prevention cylinder 21. 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 the unclean air 28.

Further, by providing the air mask 1 having a configuration in which 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 or suppression of deterioration of the health of the person 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, and the purified air 29 is not only capable of breathing the purified air in a stable manner. Since it is configured to blow air in the direction as well, it is useful because it is possible to suppress health damage caused by 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 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. It is a front view of the example of the configuration which prevents the person 49 from sucking in the unclean air 28 by the air curtain by the air 29.

In the air mask 1 having such a configuration, the unclean air 28 taken in from the unclean air port 24 of the infection control cylinder 21 passes through the air purification unit 12, and is purified or detoxified, inactivated, and sterilized by the air purification unit 12. This is an example of a configuration in which air is sent from the purified air port 23 toward the mouth of the person 49 by the fan 11 facing the purified air port 23 side.
The air purification unit 12 is a part having a structure for purifying or sterilizing the unclean air 28 taken in from the unpurified air port 24, and the structure of the air purification unit 12 may be by heating or may be.

Further, the fan 11 is an example of a configuration in which two fans 11 are provided in series in order to enhance the intake force, and by providing two or more fans 11, the resistance of the air purification unit 12 is increased. Even in a large configuration, it is possible to flow air with a larger flow rate, which is useful.

An example of the configuration of FIG. 5C is a configuration including a catalyst material 38 which is a material processed by a photocatalyst as an air purification unit 12, and a light source 20 is provided around the catalyst material 38. 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 is provided in the infection prevention cylinder 21, it is possible to use 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. 5 (d) is an example of the configuration in which the example of the configuration of FIG. 5 (a) secures the length of the air flow path 19 by providing the hairpin curve 37 in the vertical direction. However, it is an example of a configuration in which a plurality of hairpin curves 37 are provided in the lateral direction, and an example of a configuration in which the unclean air 28 is purified by providing an ultraviolet light source 20 in each of the hairpin curves 37. Is.
In this way, by providing the plurality of hairpin curves 37, the flowing air flow 17 is disturbed and turbulent, and by increasing the air flow distance, the flowing air is more evenly and firmly exposed to ultraviolet rays. This is an example of a configuration that enables exposure and enhances sterilization and purification effects.
Further, the configuration for securing the length of the air flow path 19 may be a configuration having a hairpin curve as described above, or a configuration in which the flow path 19 is provided in a spiral shape, although not shown in the drawing. Also good, not limited.

The example of the configuration of FIG. 5 (e) is an example of the configuration in which the infection control cylinder 21 has a shape that spreads downward.
With such a configuration, it is possible to increase the size of the unpurified air port 24 with respect to the size of the purified air port 23, and by having an opening capable of taking in a sufficient amount of air, the unpurified air port 24 is not related. By slowing 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.

The example of the configuration of FIG. 6 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. 6A 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. The height of the heating filter 53, the size of the outer shape, or the size of the hole becomes a ventilation resistance when an excessive load is applied to the ventilation, obstructs the flow of air, and 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 a 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 characteristics 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. 6B 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 providing the holes at different positions 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 that sterilizes, inactivates, and detoxifies viruses and the like by transmitting heat evenly to the passing air and the probability of hitting the heating filter 53 having high heat.

Although omitted in the figure of FIG. 6B, the two heating filters 53 are arranged side by side so as to be wound on the outside in a cylindrical shape or provided in the infection control 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. Further, the effect of killing the virus can be improved, and in the example of the configuration of FIG. 6B, the heating filter 53 concerned is an example of the configuration in which only two are arranged side by side, but three. 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.

An example of the configuration of FIG. 6C is a configuration in which the two heating filters 53 of the configuration of FIG. 6B are arranged side by side, and 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. 6D 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. be. With such a configuration, it is possible to heat the heating filter 53 more completely, which is useful.
Further, the heater for heating the heating filter 53 in the example of the configuration of each figure of FIG. 6 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 and the fan 11 by the electric power may be a 100V power supply, a USB power supply, 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. 7 is an example of the configuration of the mask unit 2 including the air mask 1 and the mask covering the nose and mouth.
The example of the configuration of FIG. 7A is an example of the configuration in which the person 49 wears the air mask 1 equivalent to that of FIG. 2B and the nose-nose mask 55 which is a mask covering the nose and the 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 a 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 scope of the technical idea of the present invention, that is, within the range of the shape or dimension 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 for sucking air stored in the mask hollow 58 and air entering the mask hollow 58 from the mask opening 56. 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. Although it was difficult to prevent the invasion of the mask, by making such a configuration, the purified, detoxified, sterilized, and inactivated air is constantly blown into the mask hollow 58. It is possible to prevent the inhalation of such foreign substances, viruses, pollen, gas, etc., and it 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 scope 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, by making the purification air port 23, which is the opening of the air mask 1, provided with the bellows structure 27 as shown in the example of the configuration of FIG. 3, purification is performed from a position closer to the mask opening 56. It is useful because the air 29 can be blown into the hollow mask 58.
The mouth-nose mask 55 is a mask that covers both the mouth and the nose in the drawing, but it may cover only the mouth or only the nose.

The example of the configuration of FIG. 7 (b) is an example of a front view of the person 49 of the example of the configuration of FIG. 7 (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 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 hardly leaked, 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, 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. 7 (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. 7 (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 on the surface of the mouth and nose mask 55, and the mouth and nose mask 55 can be used. 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 the virus adhering to the hand to harm the health, which is useful.

The description of the example of the configuration of FIG. 7 (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. 7 (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 stagnant 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 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 residence area of the residence air 60 is an area indicated by an elliptical broken line area on the drawing.

The example of the configuration of FIG. 8 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.
The example of the configuration of FIG. 8 (a) is an example of the person 49 wearing the mask covering the nose and mouth in the example of the configuration of FIG. 7 (a) and the air mask 1 in the example of the configuration of FIG. 4 (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 and nose mask 55 or the mask hollow 58, which is useful.
Further, by providing the emission suppressing plate 13, the stagnant air 60 is also difficult to diffuse, is difficult to mix with the surrounding air, and is useful because it is configured to be able to breathe with more purified air.

The emission suppression plate 13 may be in the shape 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, or bamboo. It may be cotton, linen, vinyl, rubber, silicon rubber, and 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 effect. Is something that can be done.

The example of the configuration of FIG. 8 (b) is an example of the configuration of FIG. 8 (a) in which the diffusion of the purified air 29 from the air mask 1 is suppressed by the emission suppression plate 13. Further, in the example of the configuration of FIG. 8B, 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 mask hollow 58 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 stagnant air 60 exhausted from the purified air port 23 is difficult to disperse 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 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 the weight. However, the rigidity may be increased as a foam material, the structure may be such that the air mask 1 can be locked to the air mask 1, and the shape and effect can be 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 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 removable, 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 it is possible to reduce the waste of resources and the cost. The removable locking structure, which can be reduced and is useful, is not shown in the drawings, but may be hook-and-loop fasteners, fasteners, hooks, strings, etc. It may be a ring, a tape, or the like, and can be changed within the scope 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, and can be freely tightened in the fall as many times as necessary.

In the example of the configuration of FIGS. 8 (c) and 8 (d), 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. 8C 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 a configuration in which 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 end of the hanging curtain 61 or the edge of the mask, the center, diagonally, vertically or horizontally, one or more, and the shape may be. It may be rod-shaped or stud-shaped, and can be changed within the scope 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 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 is within the scope of the technical idea of the present invention, that is, a shape and dimensions capable of exhibiting the same action and effect. , It can be changed within the range of material.

FIG. 9 is an example of variations in the configurations of the air mask 1 and the mouth and nose mask 55.

The example of the configuration of FIG. 9A 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. 8B 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 stagnant 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 hooking tool for a columnar mooring 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 loosened, 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 expanded and contracted 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 make 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 scope 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 that can exert the same action and effect.

In the example of the configuration of FIG. 9B, 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. 9A, the air mask 1 is an obstacle to 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 is useful without interfering with work or the like, 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, ring, hook, hole, etc., 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 that can exert the same action and effect.

Further, in the example of the configuration of FIG. 9B, the tube 33 is intubated through the gap between the mouth and nose mask 55 without 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 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. 9 (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 approximately 100% of the nostrils, so that the purified air 29 can be efficiently sent to the nose and mouth of the person 49. Further, in particular, considering that the person 49 is basically a person who is 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 for intubation in 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 the mask is so fine. 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 making the inside of the mask positive pressure.

The example of the configuration of FIG. 10 is an example of the configuration in which the mouth and nose mask 55 or the hanging curtain portion 61 includes the mask overlapping portion 65 or the hanging curtain overlapping portion 66 having a double structure.
