[0019] Hereinafter, an embodiment of the present invention will be described with reference to Figures 1 to 9. However, the technical scope of the present invention is not limited to the illustrated examples, and various modifications can be made to the embodiment described below without departing from the spirit of the present invention.

[0020] In the following description, the state in which the wearer is wearing the hat 100 with head cooling device is taken as the basis, and the direction in front of the wearer is defined as front, the direction behind the wearer as rear, the direction above the wearer as up, the direction below the wearer as down, the direction to the right of the wearer as right, the direction to the left of the wearer as left, the axis along the front-to-back direction as X-axis, the axis along the left-to-right direction as Y-axis, and the axis along the up-down direction as Z-axis. Further, when describing parts of the head cooling device-equipped hat 100, such as the head cooling device 1 and the hat 2, the directions will be defined based on the state in which they are attached to the head cooling device-equipped hat 100.

[0021] [Configuration of one embodiment] As shown in Figures 1 to 5, the hat with head cooling device 100 of this embodiment comprises a head cooling device 1 and a hat 2, and circulates air between the hat 2 and the wearer's head to evaporate sweat from the wearer's head, thereby cooling the wearer's head with the heat of vaporization generated during evaporation.

[0022] [(1) Head cooling device] As shown in Figures 1 to 5, the head cooling device 1 comprises a device main body 11 connected to the front of the hat 2, a fan 12 for introducing air into the device main body 11, a power supply unit 13 for supplying power to the fan 12, and a circuit board 14 for controlling the power supplied from the power supply unit 13 to the fan 12.The air taken into the device main body 11 from the air intake section 1122 by the fan 12 is discharged from the air discharge section 113, thereby circulating air in the space between the hat 2 and the wearer's head.

[0023] [a Device body] The device main body 11 is the part of the head cooling device 1 that forms the outer surface of the head cooling device 1 excluding electrical components such as the fan 12, power supply 13, and circuit board 14, and is formed to have the shape of a hat brim.

[0024] As shown in Figures 1 to 5, device body 11 has an upper surface portion 111 that forms the upper surface, and a lower surface portion 112 that forms the lower surface. Between the rear end of upper surface portion 111 and the rear end of lower surface portion 112, there is formed an air delivery portion 113, which is an opening for sending air taken into device body 11 by fan 12 into the space between hat 2 and the wearer's head, and there is formed an induction path 114 inside for guiding the air taken into device body 11 by fan 12 to air delivery portion 113.

[0025] [(a) Top part] The upper surface portion 111 is the part that forms the upper surface of the device main body 11, and as shown in Figures 1 to 5, is formed so as to have the shape of a hat brim when viewed in a plane, with the center rising upward in the Y-axis direction and the left and right ends curved downward.

[0026] Furthermore, the shapes of the upper surface portion 111 and the lower surface portion 112 are approximately the same in a plan view, but the front end portion and the left and right end portions of the upper surface portion 111 are larger than the lower surface portion 112, as shown in Figures 2, 4, and 5. As a result, the upper surface portion 111 is formed so as to cover the entire side surface (end portion in a plan view) of the lower surface portion 112, except for the rear end portion where the air blowing portion 113 is formed.

[0027] As shown in Figures 4 and 5, the upper surface portion 111 has a bent portion 1111 at its rear end that bends upward, and is formed so that the rear end faces upward. Note that instead of bending at a single point as shown in Figures 4 and 5, the rear end of the upper surface portion 111 may be gradually curved so that it faces upward. Also, the rear end of the upper surface portion 111 may face upward by combining bending and curving. In the present invention, "bending or curving" includes any of the cases of bending only, curving only, and a combination of bending and curving.

[0028] 5, such bent portion 1111 is formed such that the rear end of top surface portion 111 is inclined upward with respect to the X-axis and inclined backward with respect to the Z-axis at the center of top surface portion 111 in the Y-axis direction. In other words, when a state inclined 90 degrees forward from above with respect to the Z-axis is defined as 0 degrees, and a state inclined 90 degrees backward from above with respect to the Z-axis is defined as 180 degrees, bent portion 1111 is formed such that the rear end of top surface portion 111 is at an angle between 90 degrees and 180 degrees.

[0029] 4 and 5, an apparatus side connecting means 1112, which is a hook-and-loop fastener, is provided on the upper surface side of the bent portion 1111 as a connecting means for connecting the head cooling device 1 to the hat 2. Note that the apparatus side connecting means 1112 may be anything capable of connecting the head cooling device 1 to the hat 2, and buttons, fasteners, etc. may be used in addition to the hook-and-loop fastener.

[0030] [(b) Bottom part] The lower surface portion 112 is the part that forms the lower surface of the device main body 11, and as shown in Figures 2, 4, 5 and 6, is formed so as to have the shape of a hat brim in a plan view, with the center rising upward in the Y-axis direction and the left and right ends curved downward.

[0031] Further, the shapes of the lower surface portion 112 and the upper surface portion 111 in a plan view are substantially the same, but the front end portion and the left and right end portions of the lower surface portion 112 are smaller than the upper surface portion 111, as shown in Figures 2, 4, and 5. This means that the upper surface portion 111 covers the entire side surface (end portion in a plan view) of the lower surface portion 112, except for the rear end portion where the air blowing portion 113 is formed, as described above.

[0032] As shown in Figures 2, 4, 5, and 6, the lower surface portion 112 has a curved portion 1121 that curves upward at its rear end, and is formed so that the rear end faces upward. Note that instead of gradually curving as shown in Figures 2, 4, 5, and 6, the rear end of the lower surface portion 112 may face upward by bending at one point similarly to the bent portion 1111 of the upper surface portion 111. Also, the rear end of the lower surface portion 112 may face upward by combining bending and curving.

[0033] As shown in FIG. 5, such curved portion 1121 is formed in the center of lower surface portion 112 in the Y-axis direction such that the rear end portion of lower surface portion 112 is inclined upward with respect to the X-axis and backward with respect to the Z-axis.

[0034] As shown in FIGS. 2, 4, 5 and 6, an air intake portion 1122, which is an opening portion for taking in air into the fan 12, is formed in the center of the lower surface portion 112 in the Y-axis direction. The air intake portion 1122 is a circular hole formed so as to penetrate the lower surface portion 112 in the vertical direction.

[0035] As shown in Figures 4 to 6, around the air intake portion 1122 on the upper surface of the lower surface portion 112, a fan mounting wall portion 1123 is formed, which is a wall portion that protrudes upward so as to be approximately circular in a plan view. As shown in FIGS. 4 and 6, the fan mounting wall portion 1123 is formed so that a part of the rear end portion thereof in plan view is interrupted to form an opening portion 11231, and the other portion surrounds the periphery of the air intake portion 1122.

[0036] Behind the fan mounting wall 1123 on the upper surface of the lower surface portion 112, as shown in Figures 4 to 6, there is formed a first taxiway forming wall 1124 which is a wall that protrudes upwardly in a manner connecting the right end of the opening 11231 and the right rear end of the lower surface portion 112 in a planar view, and a second taxiway forming wall 1125 which is a wall that protrudes upwardly in a manner connecting the left end of the opening 11231 and the left rear end of the lower surface portion 112 in a planar view.

[0037] The length by which the first taxiway forming wall portion 1124 and the second taxiway forming wall portion 1125 protrude upward is equal to the distance between the upper surface portion 111 and the lower surface portion 112, and the first taxiway forming wall portion 1124 and the second taxiway forming wall portion 1125 are formed so that their entire upper ends are in contact with the lower surface of the upper surface portion 111, as shown in Figure 5.

[0038] As a result, a space is formed between the first taxiway forming wall 1124 and the second taxiway forming wall 1125, with no openings except for the front end connected to the opening 11231 of the fan mounting wall 1123 and the rear end connected to the air discharge section 113, and this space becomes the taxiway 114 that guides the air taken in by the fan 12 from the air intake section 1122 into the device main body 11 to the air discharge section 113.

[0039] 6, the distance in the Y-axis direction in plan view between the first taxiway forming wall 1124 and the second taxiway forming wall 1125 (the width of taxiway 114 in plan view) is equal to the width in the Y-axis direction of air sending out section 113 at the connection part with air sending out section 113 at the rear end, and is equal to the width in the Y-axis direction of opening 11231 at the connection part with opening 11231 of fan mounting wall 1123 at the front end. That is, the width of taxiway 114 in plan view gradually increases from the front end to the rear end.

[0040] As shown in FIG. 2, the underside of the lower surface portion 112 is provided with a switch 1126 for turning the power supplied to the fan 12 on / off, and an on / off display unit 1127 for displaying whether the power supplied to the fan 12 is on / off.

[0041] The configuration of the switch 1126 and the on / off display unit 1127 is not particularly limited as long as they can switch the power supplied to the fan 12 on / off and display the on / off state of the power supplied to the fan 12. The on / off display unit 1127 may, for example, include two LEDs of different colors, and the different LEDs may be illuminated in response to the on / off state of the power supplied to the fan 12. The on / off display unit 1127 may also display the strength of the power supplied to the fan 12 in addition to the on / off state of the power supplied to the fan 12.

[0042] [b Fan] The fan 12 is a device for creating an air flow that takes in air from an air intake section 1122 formed in the device body 11 and sends it out of the device body 11 from the air discharge section 113 of the device body 11, and is attached so as to be positioned above the air intake section 1122 between the upper surface 111 and the lower surface 112 of the device body 11, as shown in Figures 2, 4 and 5.

[0043] Fan 12 is a centrifugal fan that blows air in a direction approximately perpendicular to the axis of rotation, and as shown in Figures 2, 4 and 5, includes blades 121 that generate air flow, a motor 122 that rotates blades 121, and an upper cover 123 that covers the upper parts of blades 121 and motor 122.

[0044] The shape of the blades 121 is not particularly limited as long as it can blow air taken in in a direction perpendicular to the portion of the underside 112 where the air intake portion 1122 is formed (in FIG. 5, a direction tilted slightly forward relative to the upward direction) toward the side of the fan 12, i.e., in a direction perpendicular to the air intake direction (in FIG. 5, a direction tilted slightly upward relative to the rear). In addition, the motor 122 is not particularly limited as long as it can rotate the blades 121 .

[0045] As shown in FIGS. 4 and 5, the upper cover 123 includes a side portion 1231 located on the side and an upper portion 1232 located on the upper surface. When viewed in a plane, the side portion 1231 has approximately the same shape as the fan mounting wall portion 1123 formed on the underside portion 112 of the device body 11, and when viewed in a plane, a portion of the rear end portion forms an interrupted opening 12311, while the other portion is formed to surround the periphery of the blades 121. Moreover, the upper surface portion 1232 is formed so as to cover the entire upper surface of the portion surrounded by the side surface portion 1231 .

[0046] As a result, as shown in Figures 4 and 5, by attaching the fan 12 to the underside 112 of the device body 11 by combining the side portion 1231 of the upper cover 123 with the fan mounting wall portion 1123, a space without any openings is formed around the blades 121 of the fan 12, except for the opening formed by the combination of the opening 11231 of the fan mounting wall portion 1123 with the opening 12311 of the upper cover 123 and the air intake portion 1122.

[0047] [c power supply] Power supply device 13 is a device for supplying power to fan 12, and is formed of, for example, a lithium-ion battery pack. As shown in Fig. 4, power supply devices 13 are provided at two locations, located on the left and right of fan 12, between upper surface portion 111 and lower surface portion 112 of device body 11. Note that power supply device 13 located on the right side of fan 12 is not shown. The power supply device 13 and the fan 12 are connected by a cable (not shown).

[0048] The power supply device 13 may be any device capable of supplying power to the fan 12, and the specific configuration thereof is not particularly limited. Furthermore, the number of power supply devices 13 provided is not particularly limited, and only one may be provided, or a greater number of power supply devices 13 may be provided.

[0049] [d Circuit board] The circuit board 14 is a plate-like member provided with various circuits for controlling the power supplied from the power supply device 13 to the fan 12. The circuit boards 14 are provided in two locations, one on the left and one on the right of the fan 12, between the upper surface 111 and the lower surface 112 of the device body 11, corresponding to each of the power supply devices 13, as shown in Fig. 4. The circuit board 14 located on the right side of the fan 12 is not shown. Furthermore, the circuit board 14 and the power supply device 13 are connected by a cable (not shown).

[0050] The circuit board 14 may be any circuit board capable of controlling the power supplied from the power supply device 13 to the fan 12, and the specific configuration thereof is not particularly limited. Furthermore, the number of circuit boards 14 provided is not particularly limited, and it is sufficient that the number of circuit boards 14 provided corresponds to the number of power supply devices 13 provided.

[0051] [(2) Hat] 5, the hat 2 includes an outer material 21 which is a sheet-like member arranged on the outer surface side, a lining material 22 which is a sheet-like member arranged on the inner surface side, and a spacer 23 which is arranged between the outer material 21 and the lining material 22 and is formed of a plate-like member which is harder than the sheet-like member forming the outer material 21 and the sheet-like member forming the lining material 22, and is formed into a shape of a hat without a substantially hemispherical brim. The hat 2 is worn by a wearer so as to cover the head of the wearer. The outer material 21, the lining material 22, and the spacer 23 are all connected together by a method such as sewing so that no gaps are formed between them.

[0052] By forming the outer fabric 21 from a material with low air permeability and the lining 22 from a sheet-like member made of a material with moisture permeability, the air sent out from the air sending section 113 of the head cooling device 1 flows along the wearer's head, and then is discharged to the outside from an opening formed at the rear of the hat by overlapping the rear opening 211 of the outer fabric 21 and the rear opening 221 of the lining 22, as described below. This forms an air flow passage from the fan 12 attached to the head cooling device 1 to the above-mentioned opening, and by evaporating the sweat from the wearer's head, a wide range of the wearer's head can be cooled.

[0053] It should be noted that the surface of hat 2 that faces the wearer when worn is the inner surface of hat 2, and the opposite surface is the outer surface of hat 2.

[0054] [a Outer fabric] 1 to 5, the outer material 21 is a sheet-like member formed into a substantially hemispherical shape, and is a portion that forms the outer surface side of the hat 2. There are no particular limitations on the material of the sheet-like member that forms the outer material 21, and any fabric made of natural fibers such as cotton or artificial fibers such as polyester may be used.

[0055] As shown in Figs. 3 and 5, the outer fabric 21 has a rear opening 211 on the rear surface thereof, which is formed by providing a mesh-like member in an opening formed in a sheet-like member.

[0056] [b Lining] 2, 4 and 5, the lining 22 is a part that forms the inner side of the hat 2 and is formed from a sheet-like member so as to be substantially hemispherical in size and shape substantially the same as the outer material 21. There are no particular limitations on the material of the sheet-like member that forms the lining 22, and as with the outer material 21, any material that has moisture permeability may be used, such as fabric made of natural fibers such as cotton or synthetic fibers such as polyester. Note that if the lining 22 is made of a mesh-like material, the wearing comfort of the wearer can be improved.

[0057] 2 and 5, the lining 22 has a rear opening 221 formed by providing a mesh-like member in an opening formed in a sheet-like member on the rear surface. The rear opening 221 of the lining 22 is formed at a position overlapping with the rear opening 211 of the outer fabric 21.

[0058] As shown in FIG. 4, on the inner side of the lining 22 near the front end, hat side connecting means 222, which is a hook-and-loop fastener as connecting means for connecting the head cooling device 1 to the hat 2, is provided. By connecting a hook-and-loop fastener as device side connecting means 1112 provided on the head cooling device 1 and a hook-and-loop fastener as hat side connecting means 222 provided on the hat 2, the hat 2 and the head cooling device 1 can be connected as shown in Figures 1, 2, 3 and 5.

[0059] The hat-side connecting means 222 may be any means capable of connecting the head cooling device 1 to the hat 2, and may be any means corresponding to the device-side connecting means 1112 provided on the head cooling device 1.

[0060] [c spacer] The spacer 23 is provided between the outer material 21 and the lining 22 of the hat 2 as shown in FIG. 5, and serves to make the hat 2 harder and more stable in shape than if it were made up of only the outer material 21 and the lining 22, thereby preventing the hat 2 from sticking tightly to the wearer's head and making it easier for a gap to form between the hat 2 and the wearer's head. In addition, any object that has the effect of making it easier to create a gap between objects is considered to be included in the term "spacer," regardless of the means by which it is achieved.

[0061] [(a) Spacer configuration] The spacer 23 is entirely formed in a plate shape using a resin material such as polypropylene. That is, the spacer 23 is formed to be harder than the sheet-like member forming the outer fabric 21 and the sheet-like member forming the lining fabric 22.

[0062] The spacer 23 is formed symmetrically as shown in Figures 8 and 9. That is, the spacer 23 is composed of a right side portion 231, which is a portion located on the right side of the center in the Y-axis direction and located on the right side of the wearer's head when the hat 2 is worn, and a left side portion 232, which is a portion located on the left side of the center in the left-right direction and located on the left side of the wearer's head when the hat 2 is worn, and the right side portion 231 and the left side portion 232 are connected by a connection portion 233, which is located in front of the wearer's head when the hat 2 is worn.

[0063] As shown in Figures 8 and 9, the right side portion 231 and the left side portion 232 are not connected above or behind the wearer's head, but are connected only at a connection portion 233 that is located in front of the wearer's head when the hat 2 is worn.

[0064] As shown in Figures 8 and 9, the right surface portion 231 has a right opening 2311, which is an opening formed in the center when viewed from the Y-axis direction, and the left surface portion 232 has a left opening 2321, which is an opening formed in the center when viewed from the Y-axis direction.

[0065] Furthermore, as described above, the right side portion 231 and the left side portion 232 are connected only at the connection portion 233, so that the spacer 23 is formed so that the rear portion is divided into left and right portions, as shown in Figures 8 and 9, and a rear opening 211 of the outer fabric 21 and a rear opening 221 of the lining 22 are formed at a position overlapping with such a dividing portion.

[0066] As a result, the opening formed on the back of the hat 2 by overlapping these functions as an air exhaust section for exhausting air introduced into the hat 2 (into the space between the hat 2 and the wearer's head) by the head cooling device 1.

[0067] [(b) Method of forming spacers] The spacer 23 is formed by bending a flat plate-like member made of a resin material such as polypropylene into a three-dimensional shape.

[0068] As shown in FIG. 7, the plate-like member P is formed so as to have overlapping line-symmetric shapes when inverted about the symmetric axis S in a plan view.

[0069] Also, as shown in FIG. 7, the plate-shaped member P has a first protrusion P1 and a second protrusion P2 protruding to one side of the symmetric axis S, and a third protrusion P3 and a fourth protrusion P4 protruding to the other side of the symmetric axis S.

[0070] Also, as shown in FIG. 7, the first protrusion P1 is formed so that its tip is bent toward the second protrusion P2 and faces the second protrusion P2, and the third protrusion P3 is formed so that its tip is bent toward the fourth protrusion P4 and faces the fourth protrusion P4. The tip of the first protrusion P1 may be gradually curved toward the second protrusion P2 side, instead of being bent at a single point toward the second protrusion P2 side as shown in Fig. 7. The tip of the third protrusion P3 may be gradually curved toward the fourth protrusion P4 side, instead of being bent at a single point toward the fourth protrusion P4 side as shown in Fig. 7. The first protrusion P1 may be bent and curved in combination so that its tip faces the second protrusion P2 side, and the third protrusion P3 may be bent and curved in combination so that its tip faces the fourth protrusion P4 side.

[0071] 8 and 9, for such a plate-like member P, the tip of the first protrusion P1 and the tip of the second protrusion P2 are connected, and the tip of the third protrusion P3 and the tip of the fourth protrusion P4 are connected, thereby forming a spacer 23. The connection method is not particularly limited, and may be, for example, heat welding or bonding with a predetermined adhesive.

[0072] In other words, in this case, one side of the symmetric axis S on which the first protrusion P1 and the second protrusion P2 are formed becomes the right surface portion 231 of the spacer 23, and the opening surrounded by the first protrusion P1 and the second protrusion P2 becomes the right opening 2311.

[0073] Furthermore, the other side of the symmetric axis S on which the third protrusion P3 and the fourth protrusion P4 are formed becomes the left surface portion 232 of the spacer 23, and the opening surrounded by the third protrusion P3 and the fourth protrusion P4 becomes the left opening 2321.

[0074] [2 Description of usage status] The state of the hat 100 with a head cooling device according to this embodiment when in use will be described.

[0075] First, the wearer of the hat 100 with a head cooling device connects the device side connection means 1112 of the head cooling device 1 to the hat side connection means 222 of the hat 2, as shown in Figures 1, 2, 3 and 5, and then puts the hat 100 with a head cooling device on his or her head with the head cooling device 1 connected to the hat 2.

[0076] In this way, the rear surface of the curved portion 1121 of the underside portion 112 of the device body 11 of the head cooling device 1 comes into contact with the wearer's forehead, supporting the hat 100 with the head cooling device, and the air delivery portion 113 of the device body 11 of the head cooling device 1 can be positioned in front of the wearer's forehead. That is, in the device main body 11, the bent portion 1111 of the upper surface portion 111 functions not only to adjust the blowing angle of the air blown out from the air blowing portion 113 (to direct the blown air diagonally upwards) but also to connect to the hat 2, and the curved portion 1121 of the lower surface portion 112 functions not only to adjust the blowing angle of the air blown out from the air blowing portion 113 but also to support the hat with head cooling device 100 when worn.

[0077] In this state, when the switch 1126 provided on the head cooling device 1 is operated to activate the fan 12, air outside the head cooling device 1 is taken into the device body 11 of the head cooling device 1 through an opening serving as an air intake section 1122 formed on the underside section 112 of the head cooling device 1.

[0078] The air taken into the device body 11 by the fan 12 is guided to the rear end of the head cooling device 1 by a guide path 114 formed between the upper surface 111 and the lower surface 112 of the device body 11, and is discharged outside the device body 11 from the air discharge section 113.

[0079] As described above, air delivery section 113, which is located in front of the wearer's forehead, is located in the space between the hat 2 and the wearer's head, and therefore air delivered from air delivery section 113 is introduced into the space between the hat 2 and the wearer's head.

[0080] The air introduced into the space between the hat 2 and the wearer's head circulates within the space and is then discharged to the outside through the gap between the lower end of the hat 2 and the wearer's head, as well as through an opening at the back of the hat 2 formed by the overlapping rear opening 211 of the outer fabric 21, rear opening 221 of the lining 22, and the rear dividing portion of the spacer 23.

[0081] [3. Effects of the embodiment] According to the hat 100 with head cooling device of this embodiment, the device body 11 of the head cooling device 1 is equipped with an air intake section 1122 which is an opening for taking in air into the fan 12 attached to the device body 11, and an air discharge section 113 for discharging the air taken into the device body 11 by the fan 12 from the air intake section 1122 into the hat 2 (into the space between the hat 2 and the wearer's head).

[0082] This allows air sent out from air sending section 113 to circulate in the space between hat 2 and the wearer's head, evaporating sweat from the wearer's head, thereby making it possible to cool a wide area of ​​the wearer's head. Therefore, the wearer's head can be cooled more efficiently than, for example, when a cooling plate is used to cool only the part of the wearer's head that comes into contact with the cooling plate.

[0083] In addition, device main body 11 is equipped with upper surface portion 111 that forms its upper surface, and lower surface portion 112 that forms its lower surface, and air intake portion 1122 is formed on lower surface portion 112. Since air intake portion 1122 faces downward, it is easier to prevent rain, dust, etc. from entering device main body 11 through air intake portion 1122, and air intake portion 1122 becomes less noticeable, which improves the appearance of hat 100 with head cooling device.

[0084] In addition, air blowing section 113 is formed between the rear end of upper surface section 111 and the rear end of lower surface section 112, and the rear end of upper surface section 111 is bent or curved upward, and the rear end of lower surface section 112 is bent or curved upward, so that the air blown out from air blowing section 113 is directed diagonally upward (between the upward and rearward directions in FIG. 5).

[0085] This allows air to be blown in a direction along the wearer's head, making it easier for air to circulate inside the hat 2, and further improving the cooling efficiency for the wearer's head.

[0086] In addition, by providing a hook-and-loop fastener as device side connecting means 1112 for attaching the device body 11 of the head cooling device 1 to the hat 2 near the rear end of the upper surface portion 111, it becomes easy to attach the head cooling device 1 to the hat 2.

[0087] In addition, since the device main body 11 is provided with a guide path 114 that guides the air taken into the device main body 11 from the air intake section 1122 to the air discharge section 113, the proportion of air taken into the device main body 11 by the fan 12 that is not guided to the air discharge section 113 can be reduced, and the cooling efficiency for the wearer's head can be further improved.

[0088] In addition, since the guide path 114 is formed between two wall portions, a first guide path forming wall portion 1124 and a second guide path forming wall portion 1125, one end of which is located near the air intake portion 1122 and the other end of which is located near the air discharge portion 113, it becomes easier to guide the air taken into the device main body 11 by the fan 12 further to the air discharge portion 113.

[0089] In addition, since the distance (distance in the Y-axis direction) between the first taxiway forming wall portion 1124 and the second taxiway forming wall portion 1125 is wider at the end portion located near the air discharge portion 113 than at the end portion located near the air intake portion 1122, it is possible to spread the air flow formed by the fan 12 toward the air discharge portion 113 and send out air from a wide range of the air discharge portion 113.

[0090] Furthermore, since the distance (distance in the Y-axis direction) between the first guideway forming wall portion 1124 and the second guideway forming wall portion 1125 at the end portion located near the air sending portion 113 is equal to the width of the air sending portion 113, it becomes possible to send out air from the entire air sending portion 113, making it easier to circulate air over a wide area of ​​the space between the hat 2 and the wearer's head.

[0091] In addition, since the upper surface portion 111 of the device main body 11 is formed so as to cover the side surface of the lower surface portion 112 except for the rear end portion where the air blowing portion 113 is formed, it becomes easier to prevent rainwater from entering the device main body 11 between the upper surface portion 111 and the lower surface portion 112.

[0092] In addition, because fan 12, which is attached to device body 11 so as to take in air from air intake section 1122, is a centrifugal fan, it is easier to increase the wind pressure compared to, for example, the case where a propeller fan is used, and since the air taken in by fan 12 from the bottom is sent out toward the side of fan 12, there is no need to change the direction of the air flow formed by fan 12 after it is sent out from fan 12.

[0093] In addition, since the air intake section 1122 is formed on the underside of the device body 11 and the fan 12 is stored between the upper surface section 111 and the lower surface section 112 of the device body 11, the fan 12 is difficult to see from the outside, which makes it easier to improve the appearance of the hat 100 with head cooling device. In addition to the fan 12, the power supply unit 13 and circuit board 14 for operating it are also stored between the upper surface 111 and the lower surface 112 of the device body 11, making these components difficult to see from the outside, which makes it easier to further improve the appearance of the hat 100 with head cooling device.

[0094] Furthermore, by providing the hat 2 with the spacer 23 attached so as to be in contact with the outer material 21 and the lining 22, which are the sheet-like members forming the hat 2, the hat 2 becomes harder than if the hat were formed only from sheet-like members such as the outer material 21 and the lining 22, and therefore the shape of the hat becomes more stable and it is less likely to adhere to the wearer's head. This makes it easier for gaps to form around the wearer's head, thereby improving the breathability around the wearer's head when the hat is worn.

[0095] In addition, the spacer 23 has a right side portion 231 located on the right side of the head of the wearer of the hat 2, and a left side portion 232 located on the left side of the wearer's head, and the right side portion 231 and the left side portion 232 are connected by a connection portion 233 located in front of the wearer's head, making it difficult for both the portion of the hat 2 located on the right side of the wearer's head and the portion located on the left side of the wearer's head to come into close contact with the wearer's head.

[0096] In addition, since the right and left side portions 231 and 232 are connected only at the connection portion 233 located in front of the wearer's head, it becomes easier to adjust the angle at which the right and left side portions 231 and 232 are connected, making it easier to use the same spacer 23 for multiple types of hats of different sizes.

[0097] Moreover, since the spacer 23 is formed from the planar plate-like member P, it can be easily manufactured at low cost. That is, although the spacer 23 can be formed three-dimensionally from the beginning by a method such as resin molding, it is easier to form the spacer 23 from the planar plate-like member P, and is therefore advantageous in terms of cost.

[0098] In addition, since the plate-shaped member P that forms the spacer 23 is formed to have a line-symmetric shape, it is possible to form a spacer 23 that is symmetrical on the left and right sides. Also, since the plate-shaped member P has a first protrusion P1 and a second protrusion P2 that protrude to one side of the symmetric axis S, and a third protrusion P3 and a fourth protrusion P4 that protrude to the other side of the symmetric axis S, it is possible to easily form the spacer 23 by simply connecting the first protrusion P1 and the second protrusion P2, and connecting the third protrusion P3 and the fourth protrusion P4.

[0099] This also results in the formation of an opening in the spacer 23 surrounded by the first protrusion P1 and the second protrusion P2, and an opening surrounded by the third protrusion P3 and the fourth protrusion P4, thereby forming a spacer having a right opening 2311 and a left opening 2321.

[0100] In addition, by bending or curving the first protrusion P1 toward the second protrusion P2 and bending or curving the third protrusion P3 toward the fourth protrusion P4, it becomes easier to connect the first protrusion P1 and the second protrusion P2, and also easier to connect the third protrusion P3 and the fourth protrusion P4.

[0101] In addition, the hat 2 comprises an outer material 21 which is a sheet-like member arranged on the outer side, and a lining 22 which is a sheet-like member arranged on the inner side, and the spacer 23 is provided between the outer material 21 and the lining 22, so that the spacer 23 cannot be seen from either the outer side or the inner side, which makes it easier to improve the appearance of the hat 2.

[0102] Furthermore, the spacer 23 is formed so that the rear part is divided into left and right parts, and at positions corresponding to such division, a rear opening 211 is formed in the outer fabric 21 and a rear opening 221 is formed in the lining fabric 22, so that an opening through which air can be exhausted from within the hat 2 is formed at the rear side of the hat 2. This promotes the exhaustion of air from the rear side of the hat 2.

[0103] Even if the hat 2 does not have an opening on the back, it is still possible for air to be discharged from the gap between the lower end of the hat 2 and the wearer's head. However, by forming an opening on the back of the hat 2, it becomes possible for air introduced into the space between the hat 2 and the wearer's head to be discharged more smoothly after circulating within the space.

[0104] [4 Variations] A modification of the head cooling device-equipped hat 100 according to the above embodiment will now be described.

[0105] In the above description of the configuration, the hat 2 is provided with the outer material 21, which is a sheet-like member arranged on the outer surface side, and the lining 22, which is a sheet-like member arranged on the inner surface side, and the spacer 23 is provided between the outer material 21 and the lining 22. In terms of improving the appearance of the hat 2, it is preferable to provide both the outer material 21 and the lining 22 as described above, but it is also possible to provide a configuration in which the lining 22 is not provided and the spacer 23 is attached to the inner surface side of the outer material 21. In this case as well, since the spacer 23 cannot be seen when the hat is worn, there is no problem with the appearance of the hat when it is in use.

[0106] In addition, in the explanation of the above configuration, in the device main body 11 of the head cooling device 1, the first guideway forming wall portion 1124 and the second guideway forming wall portion 1125 which form the guideway 114 protrude upward from the lower surface portion 112 and have their upper ends contact the upper surface portion 111. However, instead, the guideway 114 may be formed by two wall portions protruding downward from the upper surface portion 111 and having their lower ends contact the lower surface portion 112.

[0107] In the above description of the configuration, the head cooling device-equipped hat 100 is composed of the head cooling device 1 and the hat 2 formed as separate bodies and connected by a hook-and-loop fastener, but they may be integrally formed from the beginning so as not to be detachable. In this case, too, among such integrally formed articles, the brim part on which the fan is provided corresponds to the head cooling device, and the part that is placed on the wearer's head corresponds to the hat.

[0108] In addition, in the above description of the configuration, the head cooling device-equipped hat 100 is described as being a cap-type hat having a brim only at the front as a whole, but instead, it may be formed into a hat-type hat shape having a brim around the entire circumference of the hat. In this case, the main body of the head cooling device is formed into the shape of the brim of a hat-type cap (a ring shape that goes around the entire circumference of the hat), an air intake section is provided on the underside, and an air delivery section is provided on all or part of the inner end portion that is attached to the hat.

[0109] In the above description of the configuration, the outer fabric 21 of the hat 2 has the rear opening 211, the lining fabric 22 has the rear opening 221, and these overlap with the rear divided portion of the spacer 23 to form an opening on the rear side of the hat 2, but it is also possible for the outer fabric 21 not to have the rear opening 211, and the lining fabric 22 not to have the rear opening 221, and for the entire hat to be made of a sheet-like material with low breathability. In this case, too, the rear opening of the hat 2 cannot promote the discharge of air, but it is possible for air to be discharged from the gap between the lower end of the hat 2 and the wearer's head.
