Description

[Technical field]

[0001] The present invention relates to a filter for a fan and to fan-equipped clothing. [Background technology]

[0002] In recent years, fan-equipped clothing for cooling the body has been put to practical use and is rapidly becoming more and more popular. Fan-equipped clothing has a fan attached to a garment body made of a material with low breathability to draw air into the garment body. When the fan is operated, a large amount of air is drawn into the garment body from the fan, circulates along the surface of the wearer's body or underwear, and is then discharged to the outside from air outlets formed in the openings of the collar or sleeves. As the air drawn into the garment body by the fan flows along the surface of the wearer's body or underwear, it evaporates sweat from the body, and the body is cooled by the heat of vaporization that occurs during evaporation.

[0003] Such fan-equipped clothing is expected to be used in work environments where dust and other particles are floating around. If the fan draws dust and other particles from the air into the clothing itself, there is a risk that they will stick to the wearer's body or underwear, which is unhygienic. Therefore, there is known fan-equipped clothing that is equipped with a filter on the outer side of the fan (the side where the air intake that takes in air into the fan is located), making it possible to filter the air that is taken into the clothing body through the fan (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] International Publication No. 2007 / 061088 Summary of the Invention [Problem to be solved by the invention]

[0005] In the fan-equipped garment described in Patent Document 1, a spacer is provided on the outside of the fan's intake (the air intake part that takes in air into the fan), and a filter is attached by covering this spacer. However, with this type of structure, if a fine-mesh filter with high filtering capacity is used to remove even the finest dust particles, for example, the pressure loss through the filter increases and the amount of air taken into the garment itself is significantly reduced. Therefore, it is possible to reduce the reduction in air taken into the garment body by making the spacer larger and increasing the area of ​​the filter; however, in this case, the size of the attached filter would become larger and it would protrude significantly on the outer surface of the garment body, which could get in the way of the wearer.

[0006] The objective of the present invention is to prevent a reduction in the amount of air taken into the garment body while preventing the filter size from increasing when equipping fan-equipped garments with a filter for filtering air introduced into the garment body by the fan.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] Hereinafter, embodiments of the present invention will be described with reference to Figures 1 to 14. However, the technical scope of the present invention is not limited to the illustrated examples, and various modifications can be made to the embodiments described below without departing from the spirit of the present invention. In addition, in the following description, the state in which the wearer is wearing the fan-equipped garment 100 is taken as the basis, and the direction in front of the wearer is defined as front, the direction behind the wearer is back, the direction above the wearer is up, the direction below the wearer is down, the direction of the wearer's right hand is right, the direction of the wearer's left hand is left, the axis along the front-to-back direction is the X-axis, the axis along the left-to-right direction is the Y-axis, and the axis along the up-down direction is the Z-axis. In addition, when the opening / closing means 11 of the garment body 1 is open, the direction in which the inner surface of the garment body 1 (the side that faces the wearer's body when worn) faces will be defined as the front, and the opposite direction will be defined as the back, as shown in Fig. 2. Also, when describing the fan 2 and cylindrical filter 3, the directions will be defined based on the state in which they are attached to the garment body 1.

[0020] [Configuration of the first embodiment] As shown in Figures 1 to 3, the fan-equipped wear 100 according to the embodiment comprises a wear body 1, a fan 2 that introduces air into the wear body 1, a cylindrical filter 3 that filters the air introduced into the wear body 1 by the fan 2, a power supply unit 4 that supplies power to the fan 2, and a connection cable 5 that connects the power supply unit 4 and the fan 2. The air taken into the wear body 1 by the fan 2 is circulated along the surface of the wearer's body or underwear and then discharged from air outlet sections 14 formed in the collar and sleeves of the wear body 1, thereby evaporating sweat from the body and cooling the body with the heat of vaporization generated during evaporation.

[0021] [1 Clothing body] As shown in Figures 1 to 3, the garment body 1 is made of a fabric that is either non-breathable or has a degree of breathability that allows it to be inflated by the introduction of air by a fan 2, and is formed in a shape that covers the torso and arms of the wearer. In Figures 1 to 3, the garment body 1 is formed in the shape of a blouson-type upper garment, but the shape of the garment body 1 is not limited to this as long as it covers at least a part of the wearer's body. For example, it may be formed in a vest-type that covers only the torso of the wearer. The surface of the garment body 1 that faces the wearer when worn is referred to as the inner surface, and the opposite surface of the garment body 1 that faces the outside space when worn is referred to as the outer surface.

[0022] As shown in Figures 1 to 3, the garment body 1 is provided with opening and closing means 11, which is a detachable divided part formed with a linear fastener or the like, at the front body, and air leakage prevention means 12, which is formed by providing a stretchable member such as an elastic cord that goes around the wearer's body, at the hem and is a means for preventing air in the space between the garment body 1 and the wearer's body from leaking out through the hem of the garment body 1 to the outside. In addition, an air exhaust section 14 is formed in the opening between the wearer's neck and the end of the collar of the garment body 1, and in the opening between the wearer's arm and the end of the sleeve of the garment body 1, which is an opening for exhausting air that has been introduced into the space between the garment body 1 and the wearer's body by the fan 2 after circulating it along the wearer's body or underwear.

[0023] In addition, as shown in FIG. 2, the inner surface of the garment body 1 is provided with a power supply unit holding means 15 formed in a pocket shape capable of storing the power supply unit 4 in order to hold the power supply unit 4 in a position where it can supply power to the fan 2 through the connection cable 5, and a cable holding means 16 formed in a ring shape having an opening through which the connection cable 5 can be inserted, by sewing a long piece of cloth in the vertical direction at two points, top and bottom, in order to hold the connection cable 5 on the inner surface of the garment body 1.

[0024] In addition, at positions on the back of the garment body 1 corresponding to the left and right sides of the wearer's waist, as shown in Figures 1 and 2, fan mounting holes 13 are formed which are circular holes that connect the space between the garment body 1 and the wearer's body with the space outside the garment body 1 when the fan-equipped garment 100 is worn. The diameter of the fan mounting hole 13 is formed to be approximately the same as the diameter of the tubular portion 213 of the fan body 21 of the fan 2 described below. By attaching the fan 2 to the garment body 1 so that the tubular portion 213 passes through the fan mounting hole 13, outside air can be taken in through the fan mounting hole 13 into the space between the garment body 1 and the wearer's body. It is preferable that the area around fan mounting hole 13 is reinforced by, for example, attaching a flat annular member made of plastic or the like, or by folding back and sewing the portion of the fabric that forms the garment body 1 around fan mounting hole 13.

[0025] [2 Fans] The fan 2 is a means for introducing air into the space between the garment body 1 and the wearer's body through a fan mounting hole 13, and as shown in FIG. 2, the necessary power is supplied to the fan 2 from a power supply unit 4 via a connection cable 5.

[0026] As shown in FIGS. 8 and 9, the fan 2 includes a fan body 21 and an attachment ring 22.

[0027] [(1) Fan body] The fan body 21 is a portion that forms the main body of the fan 2 and houses a propeller (not shown) that generates an air flow.

[0028] The propeller housed in fan body 21 is rotated by a motor (not shown) about a rotation axis in the front-rear direction (X-axis), thereby generating an air flow from air intake section 211 (described below) to air delivery section 212 (from rear to front). The shape of the propeller is not particularly limited as long as it can generate an air flow from air intake section 211 to air delivery section 212.

[0029] As shown in Figures 8 and 9, the fan body 21 is formed, on a portion located on the outer side of the garment body 1, with an air intake section 211 where air is taken in when the internal propeller is rotated, and, on a portion located on the inner side of the garment body 1, with an air delivery section 212 where air is delivered out when the internal propeller is rotated.

[0030] In addition, the fan body 21 has a cylindrical portion 213 between the air intake portion 211 and the air discharge portion 212, which is a cylindrical connecting portion that connects the air intake portion 211 and the air discharge portion 212, and the end of the cylindrical portion 213 on the air intake portion 211 side has a flange 214 that protrudes in a direction approximately perpendicular to the side of the cylindrical portion 213.

[0031] The tubular portion 213 is formed into a cylindrical shape whose cross section when cut along a plane (YZ plane) perpendicular to the rotation axis (X axis) of the propeller has a circular outer diameter that is approximately the same as the diameter of the fan mounting hole 13. In addition, the flange 214 protruding from the tubular portion 213 also has a circular shape when viewed from the X-axis direction. In addition, protrusions 2131 that fit into recesses formed on the inner surface of the mounting ring 22 described below are formed at two opposing locations on the outer surface of the tubular portion 213, and are configured so that the mounting ring 22 can be fixed to the outer surface of the tubular portion 213 as described below.

[0032] [(2) Mounting ring] The mounting ring 22 is a ring-shaped member formed integrally from a flexible material such as plastic, and is attached so as to cover the outer surface of the cylindrical portion 213 of the fan body 21, as shown in Figure 9, and is used to attach the fan 2 to the garment body 1 by sandwiching the area surrounding the fan mounting hole 13 of the garment body 1 between one end of the mounting ring 22 and the flange 214 of the fan body 21.

[0033] The attachment ring 22 is formed in a ring shape that has an elliptical shape when viewed in the direction of the rotation axis (X-axis direction) of the propeller inside the fan body 21. The attachment ring 22 is also formed so that the length of the inner circumference is longer than the length of the outer circumference of the cylindrical portion 213 of the fan body 21, and the minor axis of the inner circumference is smaller than or equal to the diameter of the outer circumference of the cylindrical portion 213. In this case, the major axis of the inner circumference of the attachment ring 22 is larger than the diameter of the outer circumference of the cylindrical portion 213.

[0034] In addition, at two opposing positions on the inner surface of the mounting ring 22 in the short diameter direction, recesses (not shown) are formed to fit with protrusions 2131 formed on the outer surface side of the cylindrical portion 213 of the fan body 21.

[0035] Because the mounting ring 22 has flexibility as described above, when pressure is applied from the outer surface side in the major axis direction, the minor axis direction bulges outward, deforming the mounting ring 22 into a perfect circle. When the pressure from the outer surface side in the major axis direction is released, the mounting ring 22 returns to its original elliptical shape. Utilizing this, the elliptical-shaped mounting ring 22 is pressed from the outer surface side in the long diameter direction, and is deformed into a perfect circle.Then, the position of the convex portion 2131 of the tubular portion 213 overlaps the position of the concave portion of the mounting ring 22, the mounting ring 22 is placed over the tubular portion 213, and the pressure on the mounting ring 22 is released, thereby allowing the mounting ring 22 to be attached to the tubular portion 213 of the fan body 21. At this time, the fan 2 can be attached to the garment body 1 by sandwiching the area surrounding the fan mounting hole 13 of the garment body 1 between one end of the mounting ring 22 and the flange 214 of the fan body 21.

[0036] [3 Cylindrical Filter] The cylindrical filter 3 is a means for filtering the air taken into the garment body 1 by the fan 2, and is attached to the garment body 1 so as to cover the air intake portion 211 of the fan body 21 of the fan 2, as shown in Figures 1, 3 and 9.

[0037] As shown in FIG. 7, the cylindrical filter 3 includes a filter body 31, an outer cover 32, an inner cover 33, a positioning needle 34, and a lid portion 35.

[0038] [(1) Filter body] As shown in FIGS. 3 to 5 and 7 to 9, the filter body 31 is a filter that is folded in a pleated shape and formed so as to have an annular shape when viewed from the X-axis direction. In this case, the term "annular" is not limited to a circular shape, but refers to a closed curved shape in which both ends coincide. Also, the term "pleated" broadly includes a shape in which the material is folded so that mountain folds and valley folds are alternately and continuously formed.

[0039] There are no particular limitations on the type of filter that constitutes the pleated filter, and an appropriate filter may be selected and used depending on the object to be removed from the air taken into the garment body 1.

[0040] [(2) Outer cover] As shown in Figures 1 and 3 to 9, the outer cover 32 is a circular plate-like member attached to the rear side (the side opposite to the side facing the wear body 1) of the cylindrical filter 3, and has a first opening 321, which is a circular opening, formed in the center. As shown in FIG. 8, the diameter of the first opening 321 is larger than the diameter of the flange 214 of the fan body 21, and is configured to allow the fan body 21 to pass through when the fan 2 and cylindrical filter 3 are attached to the wear body 1, as described below.

[0041] [(3) Inner cover] As shown in Figures 3 to 9, the inner cover 33 is a circular plate-like member attached to the front side (the side facing the garment body 1) of the cylindrical filter 3, and has a second opening 331, which is a circular opening, formed in the center.

[0042] As shown in FIGS. 6 and 7, the second opening 331 is a circular opening in which two opposing cutouts 3311 having an increased diameter are formed. Even if an opening includes a portion where the diameter varies, it is considered to be a circular opening if the majority of the outer edge of the opening is formed to be located on the same circumference. Also, if an opening includes a portion where the diameter varies, the diameter of the circular opening means the diameter of the portion where the diameter is smallest.

[0043] 8, the diameter of the second opening 331 is smaller than the diameter of the flange 214 of the fan body 21 and slightly larger than the diameter of a cross section of the tubular portion 213 cut along a plane (YZ plane) perpendicular to the rotation axis (X axis) of the propeller. As a result, when the fan 2 and the cylindrical filter 3 are attached to the wear body 1 as described below, of the fan body 21 that has passed through the first opening 321 of the outer cover 32, the tubular portion 213 can pass through the second opening 331, but the flange 214 cannot pass through the second opening 331.

[0044] [(4) Stereotactic needle] As shown in FIG. 7 , the positioning needle 34 is a rod-shaped member that connects the outer cover 32 and the inner cover 33 and fixes the filter body 31 to the outer cover 32 and the inner cover 33, and is attached so as to connect the edge along the first opening 321 of the outer cover 32 and the edge along the second opening 331 of the inner cover 33. Figure 7 illustrates a case where six positioning needles 34 are provided, but the number of positioning needles 34 is not limited to this, and a larger number of positioning needles 34 may be provided, or the number of positioning needles 34 may be reduced within the range in which the filter body 31, outer cover 32 and inner cover 33 are fixed.

[0045] 7, the filter body 31 is positioned outside the positioning needles 34 of the cylindrical filter 3 and is disposed so as to surround the positioning needles 34. As a result, the position of the filter body 31 is fixed by the positioning needles 34, so that the filter body 31 can be detachably attached to the cylindrical filter 3 without using adhesive or the like, and it becomes possible to replace only the filter body 31. In addition, if, rather than replacing only the filter body 31, the filter body 31, the outer cover 32 and the inner cover 33 are connected in an undetachable manner and unitized (integrated) as described below, and then replaced as a whole, the positioning needle 34 is not necessarily required.

[0046] [(5) Lid] As shown in FIGS. 1, 3 to 5, and 7 to 9, the lid portion 35 is a member for closing the first opening 321 of the outer cover 32, and is attached to the outer cover 32 in a detachable manner.

[0047] The lid portion 35 is formed in a circular plate shape that is slightly larger in diameter than the first opening 321 of the outer cover 32 and can cover the entire first opening 321, and is provided with a plurality of claw portions 351 that protrude to the front side facing the outer cover 32, as shown in Figures 7 and 8. This makes it possible to close the first opening 321 of the outer cover 32 by attaching the lid portion 35 to the outer cover 32 so that the claw portions 351 are hooked onto the peripheral edge of the first opening 321 of the outer cover 32. In Figures 7 and 8, the lid portion 35 is illustrated as having four claw portions 351, however, the number of claw portions 351 is not limited to this and a greater number of claw portions 351 may be provided, or the number of claw portions 351 may be reduced to the extent that the lid portion 35 can be attached to the outer cover 32.

[0048] [4 Power supply] The power supply device 4 is a member for supplying power to the fan 2 (a motor for rotating a propeller provided within the fan 2) and includes, for example, a built-in lithium-ion battery pack with a safety protection circuit, and is connected to the fan 2 via a connection cable 5 as shown in Fig. 2. The power supply device 4 also includes a switch for switching the power supplied to the fan 2 on and off. The power supply device 4 may be any device capable of supplying power to the fan 2, and the specific configuration thereof is not particularly limited.

[0049] [5 Connection cable] As shown in FIG. 2, the connection cable 5 is a cable that connects the power supply device 4 and the fan 2, and the power required for operating the fan 2 is supplied from the power supply device 4 to the fan 2 through the connection cable 5. The connection cable 5 may have any configuration as long as it can supply power from the power supply device 4 to the fan 2 via the connection cable 5, and the specific configuration thereof is not particularly limited.

[0050] [Second, installation method explanation] A method for attaching the fan 2 and the cylindrical filter 3 to the garment body 1 will now be described.

[0051] When attaching the fan 2 and the cylindrical filter 3 to the garment body 1, first, as shown in FIG. 8, the fan body 21 of the fan 2 and the cylindrical filter 3 with the lid 35 removed are placed on the outer surface (rear side) of the portion of the garment body 1 where the fan mounting hole 13 is formed, and the mounting ring 22 of the fan 2 is placed on the inner surface (front side) of the portion of the garment body 1 where the fan mounting hole 13 is formed.

[0052] Next, the fan body 21 is passed through the first opening 321 of the outer cover 32 into the cylindrical filter 3, so that the air delivery section 212 and the tubular section 213 of the fan body 21 protrude from the second opening 331 of the inner cover 33 of the cylindrical filter 3, and the flange 214 of the fan body 21 is hooked onto the peripheral edge of the second opening 331 of the inner cover 33 of the cylindrical filter 3. When passing the tubular portion 213 of the fan body 21 through the second opening 331 of the inner cover 33 of the cylindrical filter 3, the position of the convex portion 2131 is aligned with the position of the cutout portion 3311 to prevent the convex portion 2131 from getting caught on the edge of the second opening 331.

[0053] Next, the portion of the fan body 21 that protrudes from the second opening 331 of the inner cover 33 of the cylindrical filter 3 (the air delivery portion 212 and the tubular portion 213) is passed through the fan mounting hole 13 of the garment body 1, and then the mounting ring 22 is passed through the tubular portion 213 of the fan body 21 from the inner side of the garment body 1 and fixed.

[0054] Next, the lid portion 35 is attached to the outer cover 32 to close the first opening 321 .

[0055] As a result, by sandwiching the area surrounding the fan mounting hole 13 in the garment body 1 and the area surrounding the second opening 331 of the inner cover 33 of the cylindrical filter 3 between the flange 214 of the fan body 21 and the mounting ring 22, the cylindrical filter 3 covers the air intake portion 211 of the fan body 21 of the fan 2, as shown in Figure 9, and the cylindrical filter 3 is positioned on the outer surface side of the garment body 1, so that the cylindrical filter 3 can be attached to the fan 2 and the fan 2 and the cylindrical filter 3 can be attached to the garment body 1.

[0056] [Effects of the third embodiment] According to the fan wear 100 of this embodiment, the air intake section 211 of the fan body 21 of the fan 2 is covered by the cylindrical filter 3 having the filter body 31 formed into a ring shape by the filter folded in pleats. By using a filter folded into pleats, it is possible to increase the contact area between the filter and the outside air and reduce pressure loss without increasing the size of the cylindrical filter 3, compared to when a flat filter was used as in the past. This makes it possible to prevent the filter size from increasing and to prevent a decrease in the amount of air taken into the garment body due to the inclusion of a filter.

[0057] Furthermore, by selecting the type and shape of the filter used in the filter body 31 according to the application and replacing it as needed, it is possible to remove substances of various particle sizes from the air taken into the garment body 1 according to the characteristics of the selected filter, and it is also possible to prevent viruses and the like from being taken into the garment body 1 in addition to dust of various particle sizes. Note that in this embodiment, a pleated filter is used from the viewpoint of pressure loss as described above.

[0058] In addition, the cylindrical filter 3 is provided with an outer cover 32 on the rear side with a first opening 321 formed in the center, and an inner cover 33 on the front side with a second opening 331 formed in the center, the diameter of the first opening 321 being larger than the diameter of the flange 214 of the fan body 21 of the fan 2, and the diameter of the second opening 331 being smaller than the diameter of the flange 214 of the fan body 21 of the fan 2. As a result, as described in the explanation of the above mounting method, the cylindrical filter 3 can be easily attached to the clothing body 1 by sandwiching the peripheral edge of the second opening 331 of the inner cover 33 between the flange 214 and the peripheral portion of the fan mounting hole 13 of the clothing body 1.

[0059] Furthermore, since the cylindrical filter 3 is provided with a lid portion 35 that can be attached and detached freely so as to cover the first opening 321 of the outer cover 32, when the fan 2 and cylindrical filter 3 are attached to the garment body 1, the first opening 321 used when attaching the fan 2 and cylindrical filter 3 can be covered with the lid portion 35, thereby preventing outside air from entering the air intake portion 211 of the fan 2 from the first opening 321 without passing through the filter.

[0060] In addition, the lid portion 35 has multiple claw portions 351, and by attaching the lid portion 35 to the outer cover 32 so that the claw portions 351 are hooked onto the edge of the first opening 321 of the outer cover 32, it becomes easy to attach and detach the lid portion 35 to and from the outer cover 32.

[0061] [Fourth Variation] Next, a modification of the above embodiment will be described.

[0062] [1 Change in lid configuration] In the explanation of the above configuration, the lid portion 35 of the cylindrical filter 3 is formed into a circular plate shape whose diameter is slightly larger than the first opening 321 of the outer cover 32, and the claw portion 351 is attached by hooking it onto the surrounding portion of the first opening 321 of the outer cover 32. However, instead of this, the claw portion may be provided with a bulge portion that bulges outward in a hemispherical shape, and a recess into which such a bulge can be fitted may be provided on the edge of the first opening 321 of the outer cover 32, and the lid portion 35 may be attached to the outer cover 32 by fitting the bulge portion into such a recess.

[0063] 10, the lid portion 35A may be formed to a size sufficient to cover the entire one surface of the outer cover 32 (the rear surface facing the opposite side to where the filter body 31 is located), and then attached to cover the entire one surface of the outer cover 32. In this case, the risk of a gap occurring between the lid portion 35A and the first opening 321 of the outer cover 32 can be further reduced.

[0064] The cover 35A may be configured to be able to have a filter (not shown) attached to it, which can further improve the filtering ability of the cylindrical filter for filtering outside air.

[0065] [2. Changes to the configuration of the wearable device] In the above description of the configuration, the garment body 1 is formed in the shape of a blouson-type upper garment, but the shape of the garment body to which the fan 2 and cylindrical filter 3 are attached is not limited to this.

[0066] For example, a garment body 1A formed to cover the entire body of the wearer may be used, such as a fan-equipped garment 100A shown in FIG.

[0067] The garment body 1A covers the entire body of the wearer, including the head, hands, and feet, and is provided with a shield 17 made of a transparent and hard material such as PET (polyethylene terephthalate) in front of the wearer's face.

[0068] The garment body 1A is formed with a number of openings (shoulder openings 18a, back openings 18b, arm openings 18c, and leg openings 18d) covered with filters. The garment body 1A has no other openings other than those covered with filters. As the filter for covering these openings, similar to the filter used in the filter body 31 provided in the cylindrical filter 3, an appropriate filter may be selected according to the substance to be prevented from entering the garment body 1A.

[0069] According to this modified example, the wearer's entire body is covered, and all openings that serve as the exhaust ports for the air introduced into the garment body 1A by the fan 2 are also covered with filters. As a result, in addition to the air introduced into the garment body 1A by the fan 2, the air entering through the air exhaust ports can also be filtered by the filters, making it easier to use the fan-equipped garment 100A as protective clothing against dust, etc.

[0070] [3 Unitization of filter body, outer cover and inner cover] The cylindrical filter 3 may be configured so that only the filter body 31 can be replaced as described above, but the filter body 31, the outer cover 32, and the inner cover 33 may be unitized (integrated) by undetachably connecting them together by, for example, bonding with an adhesive, so that the entire unit including the filter body 31, the outer cover 32, and the inner cover 33 can be replaced. When the filter body 31, the outer cover 32, and the inner cover 33 are unitized (integrated) by undetachably connecting them together, the positioning needle 34 may not be provided.

[0071] The method of uniting (integrating) the filter body 31, outer cover 32 and inner cover 33 is not particularly limited, but it is preferable to provide a groove on the side of the outer cover 32A facing the filter body 31, and to provide a groove on the side of the inner cover 33A facing the filter body 31, as in the cylindrical filter 3A shown in Figures 12 to 14, so that the filter body 31 is fixed between these grooves.

[0072] Specifically, as shown in Figures 13 and 14, the outer cover 32A has an outer peripheral protrusion 322 formed around the outer edge of the front side facing the filter body 31, and an inner peripheral protrusion 323 formed around the inner edge, and a groove is formed between these protrusions. In addition, the inner cover 33A has an outer peripheral protrusion 332 formed around the outer edge of the rear side facing the filter body 31, and an inner peripheral protrusion 333 formed around the inner edge, and a groove is formed between these protrusions.

[0073] As shown in Figures 13 and 14, by sandwiching the filter body 31 between a groove formed between the outer peripheral protrusion 322 and the inner peripheral protrusion 323 of the outer cover 32A and a groove formed between the outer peripheral protrusion 332 and the inner peripheral protrusion 333 of the inner cover 33A, the filter body 31, the outer cover 32 and the inner cover 33 are connected by a method such as bonding with an adhesive, so that the filter body 31 can be stably fixed to the outer cover 32A and the inner cover 33A without using a positioning needle 34.

[0074] In addition, as shown in Figures 13 and 14, the lid portion 35B that covers the first opening 321 of the outer cover 32A has, on its front side facing the outer cover 32A, a lid portion protrusion 352, which is a cylindrical protrusion configured so that the outer circumferential size matches that of the first opening 321, instead of the claw portion 351.The lid portion protrusion 352 is configured to be fitted into the first opening 321 so as to be attached to the outer cover 32A so as to cover the first opening 321.
