(Embodiment 1)
In the present embodiment, the protective clothing 1 used for protecting the human body against foreign substances and in which the fan 21 is embedded will be described.

Foreign substances are, for example, pathogens, chemical substances, radioactive substances, etc., but any type can be used as long as they can affect the human body.

It is preferable that the protective clothing 1 is, for example, a protective clothing used for preventing infection against pathogens such as viruses and bacteria. It is more preferable that the protective clothing 1 is, in particular, protective clothing for preventing infection against highly pathogenic microorganisms such as Ebola and avian influenza. The protective suit 1 is useful for preventing infection of personnel such as doctors, nurses, and quarantine staff who perform work such as medical treatment and inspection against infection sources of high-risk pathogens such as highly pathogenic viruses.

However, the protective clothing 1 may be, for example, protective clothing used to prevent exposure to chemical substances such as poisons and chemicals. Further, the protective clothing 1 may be, for example, protective clothing used to prevent inhalation of dust containing a carcinogen such as asbestos or a radioactive substance such as nuclear waste. Further, the protective clothing 1 may be, for example, a protective clothing used for preventing exposure to radiation from a radioactive substance, and its use is not limited. Protective clothing 1 is also beneficial for protecting personnel working against high-risk substances.

The protective clothing 1 in the present embodiment is, for example, a protective clothing having a back entry (also referred to as a rear entry) specification. The back entry specification is a specification in which an opening / closing portion 12 for the user to put on and take off protective clothing is provided on the back side. The back side may or may not include the side surface. However, the protective clothing 1 may have a front entry specification in which the opening / closing portion 12 is provided on the front surface of the clothing body 11, and the position of the opening / closing portion 12 does not matter.

FIG. 1 is a front view of the protective clothing 1 in the present embodiment. The protective clothing 1 includes a clothing body 11 and one or more fans 21.

The clothing body 11 is a member that covers at least a part of the human body. At least a part is preferably a part other than the hand or the whole body as shown in FIG. 1, for example. However, at least a part may be a part other than the hands and feet, or may be a head and a torso. Alternatively, at least a part may be, for example, a part other than the head, or only the body. As described above, the range of the human body covered by the clothing body 11 does not matter.

It is preferable that the clothing body 11 is integrated with one or more members of the hood 111 covering the head or the shoe cover 112 covering the shoes. The integrated type may mean that the clothing body 11 and one or more members of the hood 111 or the shoe cover 112 are made of one cloth. Alternatively, the integrated type means that, for example, one or more members of the hood 111 or the shoe cover 112, which are separate from the garment body 11, are sewn or adhered to the garment body 11 in a non-detachable manner. But it may be.

The separate body may mean that members such as the hood 111 are formed so as to be worn in combination after being manufactured separately from the clothing body 11. It is preferable that the separate member such as the hood 111 is detachably connected to the clothing body 11 via, for example, a member such as a hook-and-loop fastener such as a magic tape (registered trademark: the same applies hereinafter). .. The member such as the hood 111 is preferably made of the same material as the clothes body 11, but may be made of a different material.

It is more preferable that the clothes body 11 is integrated with the hood 111 and the shoe cover 112. The clothing body 11 that is integrated with the hood 111 and the shoe cover 112 may be referred to as, for example, whole body protective clothing.

The hood 111 has a visor 111a made of a transparent material such as a PVC sheet or a polyester film.

FIG. 2 is a rear view of the protective clothing 1. Protective clothing 1 further comprises, for example, an opening / closing portion 12, a cord 13, one or more tabs 14, and one or more second tabs 15.

The opening / closing part 12 is a part for putting on and taking off the protective clothing 1 by the user, and is a part that can be opened / closed. It is preferable that the opening / closing portion 12 is provided at a position where the risk of foreign matter can be reduced. The position where the risk can be reduced is a position where foreign matter does not enter or is difficult to enter, and in particular, a position where foreign matter does not adhere or is difficult to adhere is preferable. Such a position is usually on the back side of the protective clothing 1.

Further, it is more preferable that the opening / closing portion 12 is provided at a position where the risk of foreign matter can be reduced and at a position where the user can easily put on and take off the protective clothing 1 by himself / herself. That is, if the opening / closing portion 12 is provided on the back side in order to reduce the risk, it is usually difficult to put on and take off the protective clothing 1 by one person. Therefore, in the present embodiment, the opening / closing portion 12 is provided at a position on the back side where it is easy for one person to attach / detach as much as possible.

The opening / closing portion 12 is provided on the back surface of the clothing body 11, for example, as shown in FIG. The back surface is the back surface of the clothing body 11. The back surface usually does not include the side surface, but may be considered to include the side surface. The back surface may be referred to as, for example, "back view".

The position of the opening / closing portion 12 is preferably, for example, a position along the center line of the back surface or its vicinity in terms of ease of removal. The center line may be, for example, the line of the spine.

The center line on the back surface is not limited to the center line in the vertical direction such as the spine line described above, but may be, for example, the center line in the horizontal direction. In the present embodiment, the term "vertical" may include the case of being substantially vertical, and the term "horizontal" may include the case of being substantially horizontal, which can be broadly understood.

However, the position of the opening / closing part 12 may be anywhere as long as it is on the back side of the clothing body 11. Further, the directionality of the opening / closing portion 12 does not matter.

It is preferable that the opening / closing portion 12 is composed of, for example, a zip-up from the viewpoint of airtightness. Zip-ups are also called, for example, zippers, fasteners, zippers and the like. However, the opening / closing part 12 may be made of a member other than the zip-up, such as a hook-and-loop fastener, a button, and a hook.

Specifically, a rift is formed on the back surface of the garment body 11, and the opening / closing portion 12 includes a pair of tapes added (for example, sewing, adhesion, etc.) to the garment body 11 along the crevice, and a pair of these tapes. It has a pair of elements (engagement teeth) provided on the side of the tape on the crevice side, and a slider for engaging and disengaging the pair of elements.

The code 13 is a code for opening / closing the opening / closing unit 12. The cord 13 is composed of, for example, a string, a woven tape, a chain, or the like, but the material thereof does not matter. The cord 13 is usually provided on a zip-up slider that constitutes the opening / closing portion 12.

The tab 14 is a portion to be pinched by a finger when the user takes off the protective clothing 1 by himself, and is provided in the opening / closing portion 12. It is preferable that the tab 14 is provided inside the opening / closing portion 12 in that it prevents the pathogen from adhering to the fingertips. The inside is a side in contact with the human body, and is a position where the opening / closing portion 12 is hidden under the opening / closing portion 12 and shielded from the outside world in a closed state.

The clothes body 11 is usually provided with one or more tabs 14 inside the opening / closing portion 12. It is preferable that one or more tabs 14 are located at the uppermost level of the opening / closing portion 12 or in the vicinity thereof. The highest position of the opening / closing portion 12 is, for example, the height of the back of the head, and the position where one or more tabs 14 are applied means that the user turns both arms so that the fingertips come to the position of the back of the head. It is preferable in that the tab 14 can be easily pinched in the state.

The second tab 15 is provided on the shoe cover 112. The second tab 15 is a portion for facilitating the user to take off the shoe cover 112 or the clothing body 11 integrated with the shoe cover 112 by himself / herself. For example, when the clothes body 11 is integrated with the pair of left and right shoe covers 112, it is preferable that the second tab 15 is provided for each of the pair of shoe covers 112. However, the second tab 15 may be provided on one of the pair of shoe covers 112, and the second tab 15 may not be provided on the other.

The second tab 15 is provided, for example, at a position corresponding to the heel of the foot of each of the pair of left and right shoe covers 112. The second tab 15 provided on the heel of the left shoe cover 112 is a portion that the user steps on with his / her right foot when he / she takes off the protective clothing 1 by himself / herself. The second tab 15 provided on the heel of the right shoe cover 112 is a portion that the user steps on with his / her left foot when he / she takes off the protective clothing 1 by himself / herself.

The fan 21 is embedded in the clothes body 11 and ventilates the inside of the clothes body 11.

To be embedded, for example, an embedding hole 11a having a shape and size corresponding to the intake hole 214a (see FIG. 4: described later) of the fan 21 is formed in the clothing body 11, and the fan 21 is formed in the embedding hole 11a. Is embedded, either fixedly or detachably. To be fixedly embedded, the outer peripheral portion of the fan 21 may be fixed to the periphery of the embedding hole 11a of the clothing body 11, for example, or may be detachably attached. Sticking means that it is fixedly or difficult to remove. The fixing is, for example, adhesion, sewing, or the like, but the mode is not limited.

Detachable embedding means, for example, that each of the clothes body 11 and the fan 21 is provided with a detachable portion, and these two detachable portions are detachably connected to each other. Specifically, for example, as shown in FIG. 3, a main body side attachment / detachment portion 11b having a convex portion is provided around the embedding hole 11a of the clothing main body 11. Further, the outer peripheral portion of the fan 21 is provided with a fan-side attachment / detachment portion 214c (see FIG. 4: described later) having a concave portion that engages with a convex portion on the main body side attachment / detachment portion 11b side. Then, when the concave portion engages with the convex portion, the fan side attachment / detachment portion 214c is coupled to the main body side attachment / detachment portion 11b, and the concave portion is disengaged from the convex portion, so that the fan side attachment / detachment portion 214c becomes the main body side attachment / detachment portion 11b. Withdraw from.

Alternatively, the main body side attachment / detachment portion 11b and the fan side attachment / detachment portion 214c may be connected by, for example, three or more screws or bolts, a snap fit, a twist lock, a magic tape, or the like, and the fan 21 can be attached / detached to / from the clothing main body 11. The mechanism that enables this is not limited.

When the fan 21 is separated from the clothing body 11, the embedding hole 11a is sealed with, for example, a circular lid 31 having a member equivalent to the fan-side attachment / detachment portion 214c. The lid 31 may have a rectangular shape, a hexagonal shape, or the like, and the shape is not limited. For example, when working without ventilation, the wearer may remove the fan from the clothing body 11 and attach the lid 31. As a result, the airtightness inside the garment body 11 is maintained, so that the wearer can work safely.

Note that the lid 31 may be provided with one or more ventilation holes, and the ventilation holes may be provided with a filter that allows air to pass through and does not allow foreign matter to pass through. The filter is made of, for example, the cloth of the mask, but the material is not limited. As a result, the air permeability is ensured while maintaining the protection performance against foreign substances, so that the wearer can comfortably and safely perform the work even when the lid 31 is attached instead of the fan 21. However, one or more vents with such a filter are not essential.

Alternatively, a unidirectional valve (not shown) may be embedded in the embedding hole 11a. The embedded unidirectional valve is a valve that allows only one of the exhaust from the inside to the outside of the clothing body 11 and the intake from the outside to the inside of the clothing body 11 and does not allow the other. Normally, a unidirectional valve that allows only exhaust from the inside to the outside of the clothing body 11 and does not allow intake from the outside to the inside of the clothing body 11 is embedded in the embedding hole 11a. The main body side attachment / detachment portion 11b may be provided around the embedding hole 11a, or may be provided in the unidirectional valve. As a result, even when the fan 21 is separated from the clothes body 11, outside air does not enter the inside of the clothes body 11, and the lid 31 becomes unnecessary.

Ventilation is to replace the air inside the clothes body 11 with the air outside the clothes body 11 (outside air).

The fan 21 is usually embedded at a position close to the mouth or nose on the front side of the clothing body 11. The reason for being implanted in such a position is that there is more exhaled air expelled from the mouth or nose than in a position far from the mouth or nose. However, the fan 21 may be embedded on the front side of the clothing body 11 at a position far from the mouth or nose, or may be embedded on the back side of the clothing body 11.

Also, the fan 21 is usually embedded at a position lower than the mouth or at the same height as the mouth. The reason for being embedded in such a position is to prevent the fan 21 from obstructing the wearer's field of vision.

The fan 21 is embedded, for example, in a position of the clothing body 11 where the distance from the position corresponding to the mouth is equal to or less than the threshold value or less than the threshold value. The distance from the position corresponding to the mouth is, for example, the distance from the center point of the mouth to the center point of the fan 21 when the wearer is wearing the protective suit 1, but is the contour line on the lower side of the mouth. , The shortest distance between the fan 21 and the contour line on the upper side may be used, and the measuring method is not limited. The threshold value is, for example, 10 cm, 15 cm, 7.5 cm, etc., but the numerical value does not matter. Needless to say, the position where the distance from the position corresponding to the mouth is equal to or less than the threshold value or less than the threshold value may be, for example, the position corresponding to the mouth. However, the mounting position of the fan 21 does not necessarily have to be near the mouth. For example, the fan 21 may be embedded at a position where the distance from the position corresponding to the mouth of the clothing body 11 is equal to or greater than the threshold value. Further, the fan 21 may be attached at a position behind the back of the head or the neck, for example.

However, the distance from the position corresponding to the mouth is, for example, the result of adding or subtracting a predetermined value (for example, the distance between the mouth and the nose) to the distance from the position corresponding to the nose. It may be a distance from a position between the mouth and the nose, a part of the body (for example, nose, jaw, etc.) or a part of the clothes body 11 (for example, visor 111a) having a predetermined positional relationship with the mouth. It may be the distance from the middle point of the lower contour line, etc.).

Further, the fan 21 is embedded in the clothes body 11 at a position corresponding to the center of the body, for example. The center of the body is, for example, a position on the axis of symmetry of the human body that is symmetrical. The axis of symmetry may be, for example, the centerline of the body or the spine. The term "on the axis of symmetry" does not have to be directly above the axis of symmetry, but can be broadly understood as long as it is located close to the axis of symmetry so that it can be regarded as above. For example, the mouth, nose, Adam's apple, navel, etc. are parts located on the axis of symmetry of the human body.

The fan 21 is embedded at a position on the axis of symmetry, for example, at a position where the distance from the position corresponding to the mouth is below or below the threshold value. Specifically, for example, as shown in FIG. 1, such a position corresponds to the middle of the left and right clavicle, but the position of the Adam's apple and the midpoint of the lower contour line of the visor 111a. It may be located X mm below the position. For example, X = 20, X = 30, and the like, but the value of X does not matter. However, the fan 21 does not necessarily have to be embedded at a position corresponding to the center of the body of the clothing body.

The fan 21 is an exhaust fan that normally exhausts the air inside the clothes body 11 to the outside of the clothes body 11. When the fan 21 exhausts air, the air pressure inside the clothes body 11 becomes lower than the air pressure of the outside air, and as a result, a part (for example, a gap of the opening / closing part 12, cuffs, etc.) or the whole (fabric) of the clothes body 11 The outside air enters the inside of the clothes body 11 through the seams and textures of the clothes. As a result of the inside of the garment body 11 being ventilated in this way, the wearer can comfortably perform the work.

When the fan 21 is an exhaust fan, it is preferable to form one or two or more intake holes for taking in outside air in the clothes body 11 and attach a filter to each of the one or more intake holes. .. Further, it is preferable that the filter is removable from the intake hole of the clothing body 11. However, one or more intake holes with such a filter are not essential.

As the filter attachment / detachment mechanism, for example, a magic tape can be used. Of the hook surface and the loop surface constituting the velcro, one is provided on the outer peripheral portion of the filter and the other is provided around the intake hole of the clothing body 11, and the hook surface and the loop surface are bonded or separated. The filter is detachably or replaceably attached to the intake hole of the clothing body 11. Alternatively, a mesh-shaped pocket may be provided in the intake hole of the clothing body 11 and a filter may be inserted into the pocket, and the method of attaching the filter does not matter.

For example, one filter may be mounted on the axis of symmetry at a position different from that of the fan 21. The position on the axis of symmetry different from that of the fan 21 is, for example, the lower side of the fan 21, but may be the upper side.

Alternatively, two or more filters may be attached at positions symmetrical with respect to the axis of symmetry. The positions symmetrical with respect to the axis of symmetry are, for example, the center of the left clavicle and the center of the right clavicle, but may be the left side and the right side of the neck. Alternatively, two or more filters may be provided on the front side and the back side of the clothing body 11.

However, the number of filters and the mounting position do not matter. Further, the clothes body 11 does not have to have this kind of filter.

The fan 21 is thin, for example, as shown in FIG. 4, which houses the propeller 211, the motor 212 that drives the propeller 211, the battery 213 that supplies power to the motor 212, the propeller 211, the motor 212, and the battery 213. It is provided with a rectangular parallelepiped housing 214.

The housing 214 is formed with an intake hole 214a for taking in air inside the clothing body 11 at a position facing the rotating surface of the propeller 211, and is taken in at a position orthogonal to the plane including the rotating surface of the propeller 211. Exhaust holes 214b are formed to discharge the exhausted air to the outside of the clothes body 11.

The position facing the rotating surface of the propeller 211 is the position facing the rotating surface of the propeller 211. Such a position is, for example, the lower surface of the rectangular parallelepiped, but may be the upper surface of the rectangular parallelepiped.

The position orthogonal to the plane including the rotating surface of the propeller 211 is the position at right angles to the plane including the rotating surface of the propeller 211. It should be noted that the right angle is not limited to a strict right angle, but may be a substantially right angle, and is widely understood. Such a position is, for example, one side of four sides of a rectangular parallelepiped.

By forming the intake hole 214a and the exhaust hole 214b at the positions as described above, efficient ventilation inside the clothing body 11 becomes possible.

However, for example, the exhaust hole 214b may be formed at a position facing the rotating surface of the propeller 211, and the intake hole 214a may be formed at a position orthogonal to the plane including the rotating surface of the propeller 211. It does not matter at which position of the housing 214 each of the 214b is provided.

The rectangular parallelepiped shape does not have to be a perfect rectangular parallelepiped. For example, the corners may be rounded, the surfaces may be curved, or one or more of the sizes or shapes may differ between the two opposing surfaces. You may.

Further, the housing 214 is not limited to a thin rectangular parallelepiped shape, and may be, for example, a thin cylindrical shape or a thin polygonal prism shape (for example, a hexagonal prism or an octagonal prism), and the shape is not limited. Further, the housing 214 may be thick, and the thickness thereof does not matter.

The term "thin" means that, for example, the maximum thickness of the housing 214 in the direction perpendicular to the rotating surface of the propeller 211 is thin enough to satisfy a predetermined condition with respect to the maximum diameter in the direction parallel to the rotating surface of the propeller 211. That is.

The maximum thickness is the thickness of the thickest portion of the housing 214 in the direction perpendicular to the rotation surface of the propeller 211, and may be said to be the maximum value of the thickness. The maximum thickness is, for example, the height from the lower surface to the upper surface of a rectangular parallelepiped, a cylinder, or the like, but may be the distance between the lowest point and the highest point of the disk.

Further, the maximum diameter is the maximum value of the delivery of the housing 214 in the direction parallel to the rotating surface of the propeller 211. The maximum diameter is, for example, a diagonal line on the upper surface or the lower surface of a rectangular parallelepiped, a diameter on the upper surface or the lower surface of a cylinder, but may be the diameter of a disk or the like.

The predetermined condition is, for example, that the ratio of the maximum thickness to the maximum diameter is in the range of 1/10 to 1/5. Alternatively, the predetermined condition may be that the ratio is, for example, in the range of 1/8 to 1/6, and the numerical range of the ratio does not matter.

By embedding a thin fan 21 in which the ratio of the maximum thickness to the maximum diameter is within such a range, the protective clothing 1 capable of ventilating the inside of the clothing body 11 is realized without impairing the wearing feeling.

The maximum diameter of the housing 214 in the direction parallel to the rotating surface of the propeller 211 is, for example, in the range of 35 mm to 100 mm. Alternatively, the maximum diameter may be in the range of 40 mm to 45 mm, the range of 50 mm to 60 mm, or more than 100 mm, and the numerical range is not limited.

Further, the maximum thickness of the housing 214 in the direction perpendicular to the rotating surface of the propeller 211 is, for example, in the range of 5 mm to 15 mm. Alternatively, the maximum thickness may be, for example, in the range of 5.5 mm to 6.5 mm, may exceed 15 mm, and the numerical range is not limited.

By embedding a small and thin fan 21 in the range where the maximum diameter and the maximum thickness are applied, a protective clothing 1 having a good balance between wearing comfort and ventilation efficiency is realized.

The intake hole 214a is usually circular, but may be, for example, an elliptical shape, an elongated rectangular shape, or the like, and the shape thereof does not matter. Further, the exhaust holes 214b may be, for example, an elongated rectangle, but may be an ellipse, an arrangement of two or more rectangles, two or more circles, or the like, and the shape thereof does not matter.

The maximum diameter of the intake hole 214a is, for example, in the range of 15 mm to 20 mm, and the maximum diameter of the exhaust hole 214b is, for example, in the range of 20 mm to 35 mm. However, the maximum diameter of both the intake hole 214a and the exhaust hole 214b may be a value smaller than the maximum diameter of the housing 214 in the direction parallel to the rotation surface of the propeller 211, and the respective numerical ranges are not limited.

The battery 213 does not have to be built in the housing 214. That is, the fan 21 does not have to be a built-in battery type. In that case, for example, a storage unit (not shown) for storing the battery 213 may be provided in the vicinity of the position where the fan 21 is embedded in the clothing body 11.

Further, it is preferable that the battery 213 is rechargeable. In this case, it is preferable that the housing 214 also has a terminal for charging the battery 213. As the terminal, for example, a micro USB terminal is preferable, but a mini USB terminal or a terminal other than USB may be used, and the type thereof does not matter.

For example, a micro USB terminal may be provided on a side surface of the housing 214 different from the side surface on which the exhaust hole 214b is formed. This eliminates the need to attach / detach the battery 213 for charging. Alternatively, the battery 213 is removable and may be charged by an external charger. However, the battery 213 may be a commercially available product such as LR44.

The housing 214 also usually has a power switch for starting or stopping the supply of power from the battery 213 to the motor 212. The power switch is provided, for example, at a position adjacent to the micro USB terminal on the side surface of the housing 214, as shown in FIG. 7, but the position does not matter.

Further, the housing 214 may contain only the propeller 211, and the motor 212 and the battery 213 may be attached to the clothing body 11 in a state of being housed in another housing, for example.

When the fan 21 is an intake fan, for example, the rotation direction of the propeller 211 is opposite to that of the exhaust fan described above, and outside air is taken in from the exhaust hole 214b, and the taken-in outside air is taken in by the intake hole. As a result, it is discharged from 214a into the clothes body 11.

Therefore, when the fan 21 is an intake fan, for example, it is preferable to provide a filter in the intake hole 214a, and it is not necessary to provide a filter in the clothing body 11. However, even when the fan 21 is an intake fan, a filter is also provided on the clothes body 11 in order to facilitate the exhaust of the air inside the clothes body 11 to the outside to ensure protection against foreign substances and to ventilate the clothes. You may enhance the sex.

In this way, when the fan 21 takes in air, the air pressure inside the clothes body 11 rises, and the air inside the clothes body 11 becomes a part of the clothes body 11 (for example, the gap between the filter and the opening / closing part 12). Alternatively, it is discharged to the outside of the garment body 11 through the whole (for example, the seams of the fabric). As a result of the inside of the garment body 11 being ventilated in this way, the wearer can comfortably perform the work.

As described above, each of the one or more fans 21 embedded in the clothing body 11 is usually an exhaust fan, but may be an intake fan. When two or more fans 21 are embedded in the clothes body 11, the two or more fans 21 may be of the same type or different types. Further, for example, one or two or more fans 21 for exhausting air and one or two or more fans 21 for air intake may be provided in the clothes body 11, regardless of the type and number of fans 21 embedded in the clothes body 11. Absent.

Then, the type and number of fans 21 to be embedded in the clothes body 11 may be determined in consideration of ventilation performance and wearing feeling. For example, as shown in FIG. 1, a fan 21 for exhausting air is provided at a position between the left and right clavicle on the front side of the clothing body 11, and as shown in FIG. 5, the back side of the clothing body 11 is provided. By providing one or two fans 21 for intake air (hereinafter referred to as intake fan 21a) at at least one position on the left or right side of the neck, one fan 21 for exhausting air and one or one fan 21 for exhausting air. High ventilation performance can be obtained by the two intake fans 21a. Further, as a result of an air flow from one or two intake fans 21a on the back side to the fan 21 on the front side through the circumference of the wearer's neck, a comfortable wearing feeling can be obtained.

In FIG. 5, when the uppermost position of the opening / closing portion 12 provided on the back side of the clothing body 11 is lower than the center of the neck, the opening / closing portion 12 is located on the front side of the clothing body 11 at a position between the left and right clavicle. A fan 21 for exhausting air may be provided, and one intake fan 21a may be provided at a position in the center of the neck on the back side of the clothing body 11. As a result, high ventilation performance can be obtained by one fan 21 for exhausting and one intake fan 21a. Further, as a result of the air flow from the intake fan 21a on the back side to the fan 21 on the front side through the circumference of the wearer's neck, a comfortable wearing feeling can be obtained.

Further, in FIG. 5, one or two intake fans 21a embedded in the back side of the clothing body 11 may be replaced with one or two filters. In this case, as compared with the case of having only one fan 21 and not having one filter, in addition to improving the exhaust performance, from one or two filters, through the circumference of the wearer's neck, As a result of the air flow toward the fan 21 on the front side, a comfortable wearing feeling can be obtained.

Hereinafter, a specific example of wearing the protective clothing 1 in the present embodiment will be described.
