[0027] Exemplary embodiments will be described below with reference to the accompanying drawings.

[0028] In addition, in this specification, the direction parallel to the central axis CA is referred to as the "axial direction". In the axial direction, the direction from the bracket 37 described later to the top cover 34 is referred to as the "one axial direction D1", and the direction from the top cover 34 to the bracket 37 is referred to as the "other axial direction D2". In addition, the direction orthogonal to the central axis CA is referred to as the "radial direction", and the rotation direction centered on the central axis CA is referred to as the "circumferential direction". In the radial direction, the direction approaching the central axis CA is referred to as the "radial inner direction", and the direction away from the central axis CA is referred to as the "radial outer direction".

[0029] In addition, in this specification, "annular" includes a shape that is seamless and continuously connected in the entire circumferential area around the central axis CA, and a shape that has one or more gaps in a part of the entire area around the central axis CA. In addition, "annular" also includes a shape that draws a closed curve on a curved surface intersecting the central axis CA with the central axis CA as the center.

[0030] In addition, in the positional relationship between any one of the orientations, lines and planes and any other one, "parallel" includes not only a state where the two do not intersect at all no matter where they extend, but also a state where they are substantially parallel. In addition, "perpendicular" and "orthogonal" include not only a state where the two intersect each other at 90 degrees, but also a state where they are substantially perpendicular and a state where they are substantially orthogonal. That is, "parallel", "perpendicular" and "orthogonal" include a state where the positional relationship between the two is angularly offset to a degree that does not deviate from the main purpose of the present invention.

[0031] In addition, these names are used only for explanation, and are not intended to limit actual positional relationships, directions, names, etc.

[0032] <1. Air supply device 100>

[0033] Figure 1 It is a cross-sectional view showing a configuration example of the air blowing device 100 according to the present embodiment when viewed from the axial direction. Figure 2It is a cross-sectional view showing a configuration example of the air sending device 100 as viewed from the radial direction. Figure 3 It is an external view of the air supply device 100 . Figure 4 1 is a block diagram showing a configuration example of a control system of the air blowing device 100 . Figure 5 1 is a perspective view showing a charging example of the air supply device 100. Figure 1 It is observed from one axial direction D1 toward the other axial direction D2. Figure 3 The cross-sectional structure of the air supply device 100 after being cut by an imaginary plane which is perpendicular to the axial direction and is a single-dot chain line I. Figure 2 is observed from the radial direction using Figure 3 The cross-sectional structure of the air supply device 100 after being cut by an imaginary plane parallel to the axial direction and along the single-dot chain line II.

[0034] like Figure 1 and Figure 2 As shown, the air supply device 100 is a centrifugal fan that sucks air from the air inlet 341 and sends out air from the air outlet 321. The air supply device 100 of this embodiment is mounted on a clothing accessory 500 such as clothing (see the following description). Figure 7 ). However, this example does not limit the use of the air supply device 100.

[0035] The air supply device 100 includes a motor 101 and an impeller 102. The motor 101 drives the impeller 102 to rotate. The impeller 102 is fixed to a rotor 1 described later of the motor 101. The impeller 102 can rotate together with the rotor 1 around the central axis CA. The impeller 102 has a hub 1021 and moving blades 1022. The hub 1021 is assembled to the rotor 1. The moving blades 1022 extend radially outward from the hub 1021 and expand at least in the axial direction. In detail, the hub 1021 is cylindrical and extends in the axial direction, and is fixed to the radial outer side surface of a rotor cylinder portion 13 described later of the rotor 1. A plurality of moving blades 1022 are arranged in the circumferential direction. The moving blades 1022 can rotate in the circumferential direction around the central axis CA extending in the axial direction according to the rotation of the rotor 1. In the present embodiment, the moving blades 1022 are arranged in the circumferential direction. Figure 1 The rotation is clockwise about the central axis CA.

[0036] The air blowing device 100 further includes a battery 103. The battery 103 is a chargeable and dischargeable power source, and in this embodiment is a secondary battery such as a lithium (Li) ion battery. The battery 103 supplies power to each component of the air blowing device 100 (and the motor 101).

[0037] In addition, the air supply device 100 further includes a power receiving unit 104. For example, Figure 4As shown, the power receiving unit 104 can receive power from an external power supply device 600 in a wireless manner and charge the battery 103 using the received power. For example, the power receiving unit 104 has a power receiving coil (not shown) electrically connected to the battery 103. In addition, the power supply device 600 has a power transmission coil (not shown). In addition, the axis passing through the center of the power transmission coil and the axis passing through the center of the power receiving coil face the same direction and pass through the inside of the power receiving coil. The power transmission coil is electrically connected to an external power source (for example, a socket supplied with power from a commercial power grid) via a power cord 601. When the air supply device 100 is placed on the power supply device 600, the power transmission coil through which current flows from the power cord 601 generates a magnetic flux toward the power receiving coil. The magnetic flux passes through the inside of the power receiving coil and generates a current in the power receiving coil by electromagnetic induction. The current is supplied to the battery 103 and the battery 103 is charged. When the charge level of the battery 103 is equal to or higher than a predetermined level (eg, 80% to 100% of the maximum capacity), the charging of the battery 103 is stopped. For example, the energization of the power receiving coil is cut off by the control of the control unit 8 described later.

[0038] In this way, for example, by placing the air supply device 100 on the power supply device 600, the battery 103 can be wirelessly charged. Therefore, it is not necessary to make a wired connection with the external power supply device 600. Therefore, the battery 103 can be easily charged.

[0039] In addition, by enabling wireless charging, the configuration of the charging connector portion (e.g., connector 51) and the power cord used for wired charging can be omitted. As a result, water and dust are difficult to intrude into the interior of the housing 3 (particularly the substrate 5), thereby improving the waterproofness and dustproofness of the air supply device 100.

[0040] In addition, the above-mentioned example does not exclude a structure in which the battery 103 and the power receiving unit 104 are omitted. In addition, a portable external power supply device may be connected to the air supply device 100 in a wired manner.

[0041] In addition, the air supply device 100 also includes a switch unit 105. In the present embodiment, the switch unit 105 is arranged at the radial outer end portion of the air supply device 100 (for example, the first outer wall portion 36 described later). However, it is not limited to this example, and the switch unit 105 can also be arranged at the other axial end portion of the air supply device 100 (for example, the bottom plate portion 371 described later), etc. The switch unit 105 is a power switching switch for the air supply device 100 and the motor 101, and their on / off can be switched by operating the switching component 1051 described later. The switching component 1051 can be any one of a button, a seesaw button, an operating lever, a sliding lever, etc. That is, the switch unit 105 can be any one of a push button switch, a seesaw switch, a toggle switch, a double in-line switch, etc.

[0042] For example, the switch unit 105 can at least stop the power supply of the battery 103. As a result, the air supply device 100 and the motor 101 can be made unable to drive. By operating the switch unit 105, the power supply from the battery 103 to each component of the air supply device 100 is stopped, thereby preventing the air supply device 100 and the motor 101 (especially the control unit 8) from consuming power, and in particular, preventing their standby power consumption. That is, when the air supply device 100 is not in use, the power consumption of the air supply device 100 (and the motor 101) is completely stopped, thereby preventing the reduction of the stored power in the battery 103. Therefore, even without recharging, the air supply device 100 can be used for a longer time.

[0043] In addition, preferably, the air supply device 100 further includes a communication unit 106. The communication unit 106 can communicate with an external device of the air supply device 100, for example, Figure 4 As shown, wireless communication with the external operating device 200 is possible. In addition, the above example does not exclude a configuration in which the communication unit 106 can perform wired communication. For example, wired communication with an external device may be possible via a communication line connected to the connector 51 described later.

[0044] The operating device 200 is, for example, a portable remote controller. Figure 4 As shown, the operating device 200 has a rotation start button 201, a rotation speed increase button 202, a rotation speed decrease button 203, a rotation stop button 204, and a sending unit 205. The rotation start button 201 accepts an operation input for starting the rotation of the rotor 1 (i.e., starting the air supply). The rotation speed increase button 202 accepts an operation input for increasing the rotation speed of the rotor 1 (i.e., the air volume). The rotation speed decrease button 203 accepts an operation input for decreasing the rotation speed of the rotor 1 (i.e., the air volume). The rotation stop button 204 accepts an operation input for stopping the rotation of the rotor 1 (i.e., stopping the air supply). In addition, the sending unit 205 can communicate with the communication unit 106, and transmits the operation input accepted by the operating device 200 as an input signal.

[0045] In addition, at least one of the air supply device 100 and the operating device 200 may further include an input unit for receiving other operation inputs.

[0046] Furthermore, the above-described example does not exclude a configuration in which the communication unit 106 and the operating device 200 are omitted.

[0047] <1-1. Motor 101>

[0048] Next, the structure of the motor 101 is described. The motor 101 includes a rotor 1 rotatable about a central axis CA extending in the axial direction. The motor 101 also includes a stator 2, a housing 3, a substrate 5, an acceleration sensor 61, a temperature sensor 62, a humidity sensor 63, a storage unit 7, and a control unit 8.

[0049] <1-1-1. Rotor 1>

[0050] The rotor 1 is rotatable about the central axis CA extending in the axial direction. As described above, the motor includes the rotor 1. The rotor 1 includes a shaft 11, a rotor cover 12, a rotor inner cylinder (symbol omitted), a rotor cylinder 13, a rotor yoke (illustration omitted), and a magnet 14. The centers thereof observed from the axial direction coincide with the central axis CA. The shaft 11 extends along the central axis CA. One axial end of the shaft 11 is connected to the rotor cover 12. The rotor cover 12 extends radially outward from the shaft 11. The rotor inner cylinder is arranged on the radially inner side of the rotor cover 12. The rotor inner cylinder is cylindrical and extends from the rotor cover 12 to the other axial direction D2, and is arranged between one axial end of the bearing retainer 33 described later and one axial end of the first bearing 331. The rotor cylinder 13 extends from the radial outer end of the rotor cover 12 to the other axial direction D2, and surrounds the stator 2. The rotor yoke is a magnetic body arranged on the radial inner side of the rotor cylinder 13, and is cylindrical and extends in the axial direction in the present embodiment. Alternatively, the rotor yoke may be composed of a plurality of yoke pieces that are plate-shaped and extend in the axial direction and are arranged in a plurality in the circumferential direction. The magnet 14 is arranged radially outward of the stator 2 and surrounds the stator 2. The magnet 14 is arranged on the radial inner side of the rotor yoke. However, this example is not limited thereto, and the rotor yoke may be omitted. That is, the magnet 14 may also be arranged on the radial inner side of the rotor tube 13. In the magnet 14, different magnetic poles (N pole and S pole) are alternately arranged in the circumferential direction. The magnet 14 may be annular surrounding the central axis CA, or may be composed of a plurality of magnet pieces arranged in the circumferential direction.

[0051] <1-1-2. Stator 2>

[0052] The stator 2 is radially opposed to the magnet 14. The stator 2 has a stator core 21, an insulator (not shown) and a coil portion 22. The stator core 21 is made of a magnetic body, and in the present embodiment is a laminate of a plurality of plate-shaped electromagnetic steel plates laminated in the axial direction. The stator core 21 is radially opposed to the magnet 14. The insulator is made of an electrically insulating material such as a resin, and is arranged on the surface of the stator core 21. The coil portion 22 is a component in which a conductive wire (not shown) is arranged on the stator core 21 via an insulator, and a plurality of the coil portions 22 are arranged in the circumferential direction. The conductive wire is, for example, an enameled copper wire, a metal wire covered by an insulating member, or the like. When a driving current is supplied to the coil portion 22, the stator 2 is excited. Thus, the stator 2 drives the rotor 1. As described above, the motor 101 includes a stator 2.

[0053] <1-1-3. Housing 3>

[0054] The housing 3 accommodates the rotor 1 and the stator 2. As described above, the motor 101 includes the housing 3. The housing 3 also accommodates the substrate 5, the impeller 102, the battery 103, and the like.

[0055] The housing 3 includes a base portion 31 , a peripheral wall portion 32 , a bearing holder 33 , a first bearing 331 , a second bearing 332 , a top cover portion 34 , a cover portion 35 , a first outer wall portion 36 , and a bracket 37 .

[0056] The base portion 31 is in the shape of a plate extending in the radial direction, and is disposed at the other axial direction D2 relative to the impeller 102, the rotor 1, and the stator 2. A part of the substrate 5 is disposed on the other axial end surface of the base portion 31.

[0057] The peripheral wall portion 32 is arranged radially outward from the impeller 102 and surrounds the impeller 102. As described above, the housing 3 includes the peripheral wall portion 32. Specifically, the peripheral wall portion 32 protrudes from the radial outer end portion of the base portion 31 toward one axial direction D1 and extends in the circumferential direction. When viewed from the axial direction, the peripheral wall portion 32 is in an arc shape surrounding the moving blades 1022.

[0058] The peripheral wall portion 32 has an exhaust port 321. When viewed from the axial direction, the exhaust port 321 is an opening between one circumferential end portion and the other circumferential end portion of the peripheral wall portion 32. The exhaust port 321 is arranged on the peripheral wall portion 32, and connects the internal space surrounded by the peripheral wall portion 32 and the external space of the housing 3. As described above, the exhaust port 321 is a part of the "first opening" of the present invention. The housing 3 has an exhaust port 321.

[0059] In addition, when viewed from the axial direction, the peripheral wall portion 32 gradually separates from the central axis CA toward the radially outward direction in front of the rotating direction of the moving blade 1022. That is, the internal space surrounded by the peripheral wall portion 32 is Figure 1The center expands in the radial direction from the left circumferential end of the exhaust port 321 toward the circumferential direction clockwise about the central axis CA.

[0060] The bearing holder 33 is cylindrical and extends in the axial direction, and protrudes from the radially inner side of the base portion 31 to the axial direction D1. The bearing holder 33 holds the first bearing 331 and the second bearing 332. The bearing holder 33 rotatably supports the shaft 11 via the first bearing 331 and the second bearing 332.

[0061] Specifically, the first bearing 331 is disposed on the radially inner side surface of the bearing holder 33 . In the present embodiment, the first bearing 331 is a sliding bearing. The first bearing 331 is cylindrical and extends in the axial direction. The shaft 11 is inserted through the first bearing 331 .

[0062] In addition, the second bearing 332 is formed of a material with high sliding properties and is arranged at the bottom of the other axial side D2 of the bearing holder 33. The second bearing 332 has a column 333 and a flange 334. The column 333 extends in the axial direction and is inserted into a hole (symbol omitted) extending from the other axial end of the shaft 11 to the one axial side D1. The center of the hole and the column 333 is consistent with the central axis CA. The flange 334 is arranged on the bottom surface of the other axial side D2 of the bearing holder 33, and extends radially outward from the other axial end of the column 333.

[0063] The bearing holder 33 holds the stator 2 . Specifically, the stator core 21 is fixed to the radially outer surface of the bearing holder 33 .

[0064] The top cover 34 extends radially, is arranged closer to the axial direction D1 than the impeller 102, the rotor 1 and the stator 2, and covers one axial end of the peripheral wall 32. As described above, the housing 3 has the top cover 34. The top cover 34 has an air inlet 341, a protection portion 342 and a marking portion 343.

[0065] The air intake port 341 is arranged on the top cover portion 34, and connects the internal space surrounded by the peripheral wall portion 32 and the external space of the housing 3. The air intake port 341 is a part of the "second opening" of the present invention. The housing 3 has an air intake port 341. The air intake port 341 is an opening of the top cover portion 34, and when viewed from the axial direction, it overlaps with the impeller 102 (especially the moving blades 1022). In the present embodiment, the radial outer end portion of the air intake port 341 is arranged radially inward of the radial outer end portion of the moving blade 1022. However, it is not limited to this example, and the radial outer end portion of the air intake port 341 may also be arranged at the same radial position as the radial outer end portion of the moving blade 1022, or may be arranged radially outward of the radial outer end portion of the moving blade 1022.

[0066] The protection part 342 has air permeability and is disposed at the air inlet 341. The protection part 342 is, for example, a frame having a plurality of linear members extending radially from the center when viewed from the axial direction, and covers the air inlet 341. The shape of the protection part 342 is not limited to this example, and may be, for example, a mesh shape.

[0067] The protection part 342 prevents the impeller 102 from contacting the user's hand or the like. In addition, a filter for preventing the intrusion of dust from the outside may be arranged in the protection part 342 (or the air inlet 341). However, this example does not exclude a structure in which the filter is not arranged.

[0068] The marking portion 343 has a specific display or shape and is arranged on the surface of the top cover portion 34. The housing 3 has a marking portion 343. In detail, the marking portion 343 is arranged on an axial end surface of the portion other than the air inlet 341 of the top cover portion 34. The marking portion 343 shows the user a location suitable for performing an action (knocking, etc.) of applying an impact (acceleration above a threshold) to the housing 3. In the present embodiment, the marking portion 343 is a display depicted on the surface of the top cover portion 34, but it may also be a component arranged on the surface of the top cover portion 34.

[0069] The cover portion 35 extends radially outward from one axial end portion of the peripheral wall portion 32. The cover portion 35 is disposed at one axial end portion of the peripheral wall portion 32 and one axial end portion of the first outer wall portion 36 to cover the space between the two.

[0070] The first outer wall portion 36 extends from the radial outer end portion of the cover portion 35 to the other axial direction D2 and expands in the circumferential direction. The first outer wall portion 36 is arranged radially outward of the peripheral wall portion 32 and surrounds the peripheral wall portion 32. When viewed from the axial direction, the first outer wall portion 36 is in the shape of an arc surrounding the peripheral wall portion 32. In the present embodiment, the first outer wall portion 36 has a guide wall 361. When viewed from the axial direction, the guide wall 361 extends from one circumferential end portion ( Figure 1 The guide wall 361 also extends in the axial direction. In addition, the other circumferential end (the left circumferential end) of the first outer wall portion 36 extends to one circumferential end of the peripheral wall portion 32 and connects the two. Figure 1 The right circumferential end portion of the peripheral wall portion 32 is connected to the other circumferential end portion of the peripheral wall portion 32.

[0071] In addition, the guide wall 361 is connected to the base portion 31, the top cover portion 34, the peripheral wall portion 32, and the other circumferential end portion of the first outer wall portion ( Figure 1 The right circumferential end portion of the housing 3 together constitutes an airflow passage 362. The airflow passing through the airflow passage 362 is sent out from the exhaust port 321 and sent out to the outside of the housing 3.

[0072] The bracket 37 is disposed on the other axial direction side D2 of the first outer wall portion 36 to cover the first outer wall portion 36. The bracket 37, together with the base portion 31 and the first outer wall portion 36, forms a space for storing the substrate 5 and the battery 103.

[0073] The bracket 37 has a bottom plate portion 371 , a second outer wall portion 372 , and a first curved surface 373 .

[0074] The bottom plate portion 371 is disposed at the other axial direction D2 relative to the base portion 31 and extends in the radial direction. The battery 103 is disposed on one axial end surface of the bottom plate portion 371 .

[0075] The second outer wall portion 372 extends from the radial outer end portion of the bottom plate portion 371 in the axial direction D1 and in the circumferential direction. The second outer wall portion 372 is annular and surrounds the battery 103 , and is connected to the other axial end portion of the first outer wall portion 36 .

[0076] The first curved surface 373 is a curved surface that is inclined toward one axial direction D1 as it moves toward the radially outward direction, and extends in the circumferential direction. The first curved surface 373 is disposed between the other axial end surface and the radially outer side surface of the housing 3. In detail, the first curved surface 373 extends along the outer edge portion (radial outer end portion) of the other axial end portion of the bracket 37 (or the housing 3). The first curved surface 373 is a so-called R chamfered portion, formed at the corner formed by the radially outer end portion of the bottom plate portion 371 and the other axial end portion of the second outer wall portion 372.

[0077] <1-1-4.Substrate 5>

[0078] The substrate 5 carries various electronic components such as the drive circuit of the stator 2 (e.g., the inverter 20). In addition, a connector 51 that can be connected to an external connection line is arranged on the substrate 5. The external connection line electrically connects the substrate 5 to an external device (e.g., an external power supply) of the air supply device 100. In this embodiment, the connector 51 can be connected to, for example, a USB cable. The substrate 5 can receive power from the external device via the USB cable.

[0079] <1-1-5. Sensors 61, 62, 63>

[0080] Next, the sensors 61 , 62 , and 63 mounted on the air blowing device 100 will be described.

[0081] The acceleration sensor 61 detects the acceleration applied to the housing 3. As described above, the motor 101 is provided with the acceleration sensor 61. The acceleration sensor 61 detects the impact (acceleration) caused by the user's knocking on the housing 3, and sends the detection result to the control unit 8. In the present embodiment, the acceleration sensor 61 is mounted on the substrate 5. However, this example does not exclude the structure in which the acceleration sensor 61 is mounted on a component other than the substrate 5. For example, the acceleration sensor 61 may also be arranged on the back side (i.e., the other axial end face) of the top cover portion 34.

[0082] The temperature sensor 62 detects the temperature inside the housing 3, preferably the temperature of the airflow sent to the outside of the housing 3. The humidity sensor 63 detects the humidity inside the housing 3, preferably the humidity of the airflow sent to the outside of the housing 3. For example, in this embodiment, the temperature sensor 62 and the humidity sensor 63 are respectively arranged inside the peripheral wall portion 32, and detect the temperature and humidity of the airflow sent from the exhaust port 321. The detection results of the temperature sensor 62 and the humidity sensor 63 are sent to the control unit 8.

[0083] In the present embodiment, the temperature sensor 62 and the humidity sensor 63 are arranged on one axial end surface of the base portion 31. However, the present invention is not limited to this example, and at least one of the two may be arranged on the radial inner side surface of the peripheral wall portion 32, or on the other axial end surface of the top cover portion 34. Alternatively, at least one of the two may be arranged on the exhaust port 321 side (for example, the airflow passage 362).

[0084] In addition, the above-mentioned example does not exclude a structure in which one of the two is omitted. That is, the motor 101 may be provided with at least one of the temperature sensor 62 and the humidity sensor 63 .

[0085] <1-1-6. Storage unit 7>

[0086] The storage unit 7 is a non-temporary storage medium that retains stored information even when power supply is stopped (see Figure 4 The storage unit 7 stores data and programs used by the components of the air supply device 100 (particularly the control unit 8). In addition, the storage unit 7 stores information received through the communication unit 106 (for example, input information of the operating device 200) and the like.

[0087] <1-1-7. Control unit 8>

[0088] The control unit 8 controls the motor 101 and each component of the air supply device 100 using a program, data, etc. stored in the storage unit 7, for example (see Figure 4 ).

[0089] For example, the control unit 8 controls the energization of the stator 2. As described above, the motor 101 includes the control unit 8. For example, the stator 2 is driven by the drive current supplied from the inverter 20. The control unit 8 controls the magnetic drive of the stator 2 by controlling the inverter 20, thereby controlling the rotation of the rotor 1.

[0090] For example, the control unit 8 implements a rotation speed change of the rotor 1 based on the detection result of the acceleration sensor 61. Specifically, the control unit 8 implements any one of starting the rotation of the rotor 1, increasing or decreasing the rotation speed of the rotor 1, and stopping the rotation of the rotor 1. That is, the "rotation speed change" of the rotor 1 includes starting the rotation of the rotor 1 and stopping the rotation of the rotor 1. Hereinafter, implementation of the "rotation speed change" refers to implementation of any one of starting the rotation of the rotor 1, increasing or decreasing the rotation speed of the rotor 1, and stopping the rotation of the rotor 1.

[0091] Thus, by, for example, knocking the housing 3, the rotor 1 can be started to rotate, at least one of the rotation speed increase and decrease, and the rotation can be stopped. That is, the air supply of the air supply device 100 can be started, at least one of the increase and decrease of the air supply amount, and the air supply can be stopped. Therefore, the operation of the motor 101 and the air supply device 100 can be switched by a simple operation.

[0092] Preferably, the control unit 8 controls the energization of the stator 2 based on the acceleration in the axial direction detected by the acceleration sensor 61 and above the threshold value. In addition, the threshold value may be preset at the time of factory shipment, or may be set by an input unit or operating device (see Figure 4 ) is set to the user's expected value. In this way, the control unit 8 can control the stator 2 without being affected by the acceleration that is less than the threshold value (especially the axial component of the acceleration), the acceleration component in the direction intersecting the axial direction, etc. Therefore, the detection accuracy of the operation of switching the action of the rotor 1 can be improved. However, this example does not exclude a structure that controls the power supply to the stator 2 based on the acceleration that is less than the threshold value in the axial direction. In addition, this structure does not exclude a structure that controls the power supply to the stator 2 based on the acceleration in the direction intersecting the axial direction.

[0093] At this time, for example, each time the control unit 8 detects acceleration equal to or greater than a threshold value, it controls the stator 2. Thus, the control unit 8 switches the operation of the rotor 1 in the order of starting rotation, increasing or decreasing the rotation speed, and stopping rotation. Fig. 6A 1 is a flowchart showing a control example of the motor 101 and the air blowing device 100 . Figure 6B 1 is a flowchart showing another control example of the motor 101 and the air supply device 100. Fig. 6A and Figure 6B At the beginning, the switch unit 105 is turned on, and the motor 101 and the air supply device 100 can be driven.

[0094] For example, in Fig. 6A In the embodiment, when the user first taps the housing 3, the rotor 1 starts to rotate at a low speed, and an airflow with a minimum air volume setting is sent out from the air sending device 100 (step S101).

[0095] Next, when the user knocks on the housing 3, the rotation speed of the rotor 1 and the air volume sent from the air supply device 100 are increased by one level (step S102). In addition, the process of step S102 can be a single process or a plurality of processes and the increase of the rotation speed and the air volume can be increased in stages. Alternatively, when the rotation speed and the air volume of the rotor 1 in step S101 are set to the maximum, the rotation speed and the air volume can be reduced in step S102.

[0096] Next, when the user strikes the housing 3, the rotation of the rotor 1 stops, and the air blowing of the air blowing device 100 stops (step S103). Then, the process returns to S101.

[0097] On the other hand, even in any of the processing steps S101 to S103, when the switch unit 105 is switched from on to off, the motor 101 and the air supply device 100 cannot be driven. Fig. 6A The processing is finished.

[0098] Through Fig. 6A As shown, the rotation speed is changed every time an acceleration equal to or higher than a threshold value is detected, and for example, the operation of the rotor 1 can be switched in the above order every time the housing 3 is struck. Therefore, the operation of the motor 101 and the air blowing device 100 can be switched by a simple operation.

[0099] Alternatively, the control unit 8 may change the rotation speed of the rotor 1 by controlling the energization of the stator 2 based on the number of accelerations greater than or equal to a threshold value detected within a predetermined period.

[0100] In e.g. Figure 6B If a single tap is detected within a predetermined period (eg, 0.5 [sec]) ("Yes" in step S201), the rotor 1 starts rotating at a low speed, and the air flow with the minimum air volume setting is sent from the air supply device 100 (step S202). Then, the process returns to S201.

[0101] Alternatively, when two consecutive knocks are detected within a predetermined period ("No" in step S201 and "Yes" in step S203), the rotor 1 starts to rotate at a higher speed than step S202. Therefore, the air supply device 100 sends out an airflow with a higher air volume than step S202 (step S204). In addition, in a case where the rotor 1 is already rotating, in step S204, the rotation of the rotor 1 and the air volume of the air supply device 100 are increased by one level compared to step S202. Then, the processing returns to S201. In addition, the process of steps S203 to S204 can be a single process or a plurality of processes and the increase in the rotation speed and the air volume is increased in stages. Alternatively, in a case where the rotation speed and the air volume of the rotor 1 in step S202 are set to the maximum, the rotation speed and the air volume can also be reduced in the process of step S204.

[0102] Alternatively, when three consecutive knocks are detected within a predetermined period ("No" in steps S201 and S203 and "Yes" in S205), the rotation of the rotor 1 stops, and the air supply of the air supply device 100 stops (step S206). Figure 6B The processing returns to S201.

[0103] Furthermore, when four or more consecutive taps are detected within a predetermined period ("Yes" in step S201 and "No" in S201, S203, and S205), Figure 6B The process returns to S201. Figure 6B In the example, after entering step S206, the process may return to step S201.

[0104] On the other hand, even in any of the processing steps S201 to S206, when the switch unit 105 is switched from on to off, the motor 101 and the air supply device 100 cannot be driven. Figure 6B The processing is finished.

[0105] Through Figure 6B As shown, the rotation speed is changed according to the number of acceleration detections above the threshold value within a predetermined period, and any of the rotation start, rotation increase, rotation decrease, and rotation stop of the rotor 1 can be immediately implemented. Therefore, the operation of the motor 101 and the air supply device 100 can be switched by simple operation.

[0106] In addition, Figure 6B In the example, the predetermined period and the number of consecutive taps within the predetermined period are not limited to the above examples. For example, the predetermined period may be preset at the time of factory shipment, or may be set by an input unit or operating device 200 (see FIG. Figure 4 ) is set as the user's desired value. The number of consecutive taps within a predetermined period can also be set in the same manner.

[0107] In addition, as described above, the motor 101 includes at least one of the temperature sensor 62 and the humidity sensor 63. Preferably, the control unit 8 further changes the rotation speed of the rotor 1 based on the detection result of the at least one of the above sensors. In this way, the rotation speed of the rotor 1, the on / off of the air supply of the air supply device 100, or the air volume can be adjusted according to the temperature detected by the temperature sensor 62 and the humidity detected by the humidity sensor 63.

[0108] For example, when the temperature detected by the temperature sensor 62 is above a first temperature threshold (eg, 32° C.), or the humidity detected by the humidity sensor 63 is above a first humidity threshold (eg, 50% RH), the control unit 8 starts the rotation of the rotor 1 and the air supply of the air supply device 100 .

[0109] In addition, the rotation speed level of the rotor 1 may be single or multiple. For example, when the temperature detected by the temperature sensor 62 is greater than or equal to a first temperature threshold and less than or equal to a second temperature threshold (e.g., 34° C.), or when the humidity detected by the humidity sensor 63 is greater than or equal to a first humidity threshold and less than or equal to a second humidity threshold (e.g., 60% RH), the control unit 8 rotates the rotor 1 at a first rotation speed.

[0110] When the temperature detected by the temperature sensor 62 is higher than the second temperature threshold value (e.g., 34° C.), or the humidity detected by the humidity sensor 63 is higher than the second humidity threshold value (e.g., 60% RH), the control unit 8 rotates the rotor 1 at a second rotation speed that is one level higher than the first rotation speed. Even when there are three or more temperature threshold values ​​and humidity threshold values, the rotor 1 is similarly set to a rotation speed that is allocated to the temperature range determined by the temperature threshold value and the humidity range determined by the humidity threshold value.

[0111] When the temperature detected by the temperature sensor 62 is lower than a first temperature threshold (eg, 32° C.) or the humidity temperature detected by the humidity sensor 63 is lower than a first humidity threshold (eg, 50% RH), the control unit 8 stops the rotation of the rotor 1 .

[0112] The speed change based on the detected temperature and humidity is particularly effective in the motor 101 for the air supply device 100 installed in the clothing accessory 500 as described later. For example, based on the above-mentioned detected temperature and humidity, the temperature and humidity inside the clothing accessory 500 can be promoted to decrease, or excessive decrease can be prevented. Therefore, the control unit 8 can adjust the inside of the clothing accessory 500 to a comfortable temperature and humidity.

[0113] In addition, in the above Fig. 6A Step S102 and Figure 6BThe range of the rotation speed of the rotor 1 in which the rotation speed can be changed in step S204 may be changed based on the temperature detected by the temperature sensor 62 or the humidity detected by the humidity sensor 63 .

[0114] For example, the range in which the rotation speed of the rotor 1 is the lowest is called the first rotation speed range. Also, the range in which the rotation speed of the rotor 1 is higher than the first rotation speed range is called the second rotation speed range. Also, the range in which the rotation speed of the rotor 1 is higher than the second rotation speed range is called the third rotation speed range.

[0115] At this time, when the detected temperature is less than the first temperature threshold, or the detected humidity is less than the first humidity threshold, the control unit 8 may also select the low speed rotation mode. Fig. 6A or Figure 6B The speed changes accordingly to the tapping operation.

[0116] In addition, when the detected temperature is above the first temperature threshold and below the second temperature threshold, or the detected humidity is above the second humidity threshold and below the second humidity threshold, the control unit 8 may also select the medium speed rotation mode. Fig. 6A or Figure 6B The speed changes accordingly to the tapping operation.

[0117] In addition, when the detected temperature is above the second temperature threshold or the detected humidity is above the second humidity threshold, the control unit 8 may select the high speed rotation mode. Fig. 6A or Figure 6B The speed changes accordingly to the tapping operation.

[0118] In addition, in the above determination, priority may be given to the detection of temperature or priority may be given to the detection of humidity.

[0119] In addition, the speed change may be implemented by means other than tapping. Preferably, the control unit 8 also implements the speed change of the rotor 1 based on the signal received from the operating device 200. For example, the external operating device 200 receives the operation input of starting the rotation of the rotor 1, increasing or decreasing the speed, and stopping the rotation (see Figure 4). The communication unit 106 receives an input signal corresponding to the operation input. The control unit 8 controls the movement of the rotor 1 according to the content of the speed change corresponding to the input signal. As a result, the user can easily operate the air supply device 100 and the motor 101 without directly contacting the air supply device 100. This effect is particularly effective in the motor 101 for the air supply device 100 assembled on the clothing accessory 500. Even if the air supply device 100 is installed in a part of the clothing accessory 500 that is difficult for the user to directly contact (the inside, the upper side of the back part, etc.), the air supply device 100 and the motor 101 can be easily operated.

[0120] <1-2. Application example of the air blowing device 100>

[0121] Next, refer to Figure 2 as well as Figures 7 to 8B , an application example of the air supply device 100 is described. Figure 7 1 is a schematic diagram showing an example of a clothing accessory 500 equipped with the air supply device 100. Fig. 8A This is an enlarged view showing an example of assembly of the air supply device 100 of an application example as viewed from the inside of a clothing accessory 500 . Figure 8B 1 is an enlarged view showing another example of assembly of the air supply device 100 of the application example as viewed from the inside of the clothing accessory 500. Fig. 8A and Figure 8B The air supply device 100 is viewed from the axially other direction D2 toward the axially one direction D1 .

[0122] like Figure 7 As shown, the clothing accessory 500 is equipped with the air supply device 100. In this way, the action of the air supply device 100 can be switched by a simple operation such as knocking the housing 3. Therefore, the internal environment (temperature, humidity, etc.) of the clothing accessory 500 can be made comfortable. Therefore, the user is not likely to feel uncomfortable such as hot and stuffy, and can wear the clothing accessory 500 comfortably.

[0123] In this embodiment, the clothing decoration 500 is a garment such as a coat (upper). Two air supply devices 100 are mounted on the back of the coat. However, the mounting position of the air supply device 100 is not limited to this example. For example, the air supply device 100 may also be mounted on the front of the coat. In addition, the number of air supply devices 100 mounted may also be a single one or more than three.

[0124] Preferably, the top cover 34 of the air supply device 100 is arranged on the outside of the clothing decoration 500 and exposed to the outside of the clothing decoration 500. In addition, in this embodiment, the portion other than the top cover 34 in the housing 3 is arranged on the inside of the clothing decoration 500 (see, for example, Figure 2 and Figure 7). In this way, the user can easily knock on the top cover portion 34, and the impact (ie, acceleration) caused by the knocking can be efficiently transmitted to the acceleration sensor 61.

[0125] More preferably, the marking portion 343 is exposed outside the clothing accessory 500. In this way, the user can transmit the impact (ie, acceleration) caused by the knock to the acceleration sensor 61 more efficiently.

[0126] In addition, the air inlet 341 and the protective part 342 of the top cover part 34 are exposed to the outside of the clothing decoration 500. In addition, it is preferred that a part of both are exposed. More preferably, both are exposed as a whole. In this way, the air supply device 100 can suck the air outside the clothing decoration 500 from the air inlet 341. In addition, after the air flow sent from the air supply device 100 flows through the inside of the clothing decoration 500, it is discharged to the outside from the gap connecting the inside and outside of the clothing decoration 500. Therefore, the air in the clothing decoration 500 can be replaced. Therefore, the user can wear the clothing decoration 500 comfortably.

[0127] However, the above example does not exclude a structure in which at least a portion of the top cover portion 34 (particularly the marking portion 343) is disposed on the inner side of the clothing accessory 500. In addition, the above example does not exclude a structure in which the air inlet 341 and the protection portion 342 of the top cover portion 34 are disposed as a whole inside the clothing accessory 500 and are not exposed to the outside. According to the latter, the user's body surface temperature can be lowered by circulating the air inside the clothing accessory 500. In addition, the sweat on the body surface can be evaporated, and the inner surface of the clothing accessory 500 can be suppressed or prevented from sticking to the body surface.

[0128] In addition, it is preferred that the switch portion 105 is disposed on the inner side of the clothing decoration 500 in the housing 3. For example, in this embodiment, Fig. 8A and Figure 8B As shown, the switch portion 105 is arranged on the first outer wall portion 36, and the first outer wall portion 36 is arranged on the inner side of the clothing decoration 500. In this way, it is possible to prevent the switch portion 105 from being visually confirmed from the outer side of the clothing decoration 500. Therefore, it is possible to prevent the beauty of the air supply device 100 mounted on the clothing decoration 500 from being damaged. In addition, a physical switch component such as the switch portion 105 may not be arranged on the top cover portion 34. Therefore, it is difficult for water and dust to invade the interior of the housing 3 (especially the substrate 5). Therefore, the waterproofness and dustproofness of the air supply device 100 can be improved.

[0129] Next, the clothing decoration 500 has a cloth 510 of a top, a mounting portion 520, and an opening 530. The opening 530 is formed in the cloth 510. The mounting portion 520 is arranged along the outer edge of the opening 530. The air supply device 100 is detachably mounted on the mounting portion 520. The top cover portion 34 of the air supply device 100 is inserted into the opening 530 from the inside of the cloth 510 and exposed to the outside of the clothing decoration 500.

[0130] The mounting portion 520 includes a base frame portion 521 , a protruding wall portion 522 , and a covering portion 523 .

[0131] The base frame 521 is a plate-shaped frame extending along the inner surface of the fabric 510 and fixed to the fabric 510. In the present embodiment, the base frame 521 is arranged in a ring shape along the outer edge of the opening 530. Preferably, the inner edge of the base frame 521 contacts the radial outer end of one axial end of the housing 3 (for example, the cover 35). However, this example does not exclude a structure in which the base frame 521 does not contact the housing 3.

[0132] The protruding wall portion 522 protrudes from the base frame portion 521 toward the inner side of the clothing decoration 500 (in other words, the axial direction D2), and extends along the outer edge of the opening 530. In addition, the protruding wall portion 522 extends along the first outer wall portion 36 and the second outer wall portion 372 of the air supply device 100 (for example, see Figure 2 ). The inner peripheral surface of the protruding wall portion 522 on the side of the opening 530 is connected to the first outer wall portion 36 and the second outer wall portion 372. Thus, the protruding wall portion 522 prevents the movement of the air supply device 100 in the direction in which the base frame portion 521 expands (in other words, in a direction perpendicular to the axial direction). Preferably, the protruding wall portion 522 is flexible and can bend from the inside to the outside of the opening 530 when viewed from the inside and outside directions of the clothing accessory 500. That is, when viewed from the axial direction, the protruding wall portion 522 can bend in the radial direction.

[0133] The covering portion 523 is disposed at the front end of the protruding wall portion 522. The covering portion 523 extends toward the inside (radial direction D2) of the opening 530 as it moves toward the inside of the clothing accessory 500 (the other axial direction D2) (see Figure 2 The cover portion 523 prevents the air supply device 100 from moving toward the inner side (the other axial direction D2) of the clothing accessory 500 (see Figure 2). For example, the covering portion 523 contacts the first curved surface 373 of the air supply device 100. In addition, the first curved surface 373 is an example of the "engaging portion" of the present invention. The shell 3 has a first curved surface 373. The covering portion 523 is an example of the "engaged portion" of the present invention. That is, the first curved surface 373 engages with the covering portion 523 arranged on the inner side of the clothing accessory 500. In addition, the contact of the covering portion 523 with respect to the first curved surface 373 is an example of the "engaging structure (of the engaging portion and the engaged portion)" of the present invention, and extends circumferentially along the radial outer end of the other axial end of the shell 3. In this way, through the contact of the covering portion 523 with respect to the first curved surface 373, the air supply device 100 can be easily assembled to the clothing accessory 500.

[0134] The cover portion 523 has a second curved surface 524. The second curved surface 524 is an inner peripheral surface (radially inner surface) of the cover portion 523 on the opening 530 side (see Figure 2 ). The second curved surface 524 of the covering portion 523 contacts the first curved surface 373 of the housing 3. Figure 2 As shown, when viewed from a direction perpendicular to the axial direction and the radial direction, the first curved surface 373 and the second curved surface 524 extend radially inwardly toward the other axial direction D2. In this way, by connecting the first curved surface 373 on the air supply device 100 side with the second curved surface 524 on the clothing decoration 500 side, the assembly of the air supply device 100 relative to the clothing decoration 500 can be suppressed or prevented from being released.

[0135] For example, Fig. 8A As shown, the covering portion 523 and the protruding wall portion 522 extend in a ring shape over the entire circumferential area. In other words, the contact of the covering portion 523 with respect to the first curved surface 373 extends in a ring shape over the entire circumference of the radial outer end portion of the housing 3. In this way, by fitting the air supply device 100 to the mounting portion 520 on the clothing decoration 500 side, the air supply device 100 can be easily assembled to the clothing decoration 500. Moreover, by the contact of the covering portion 523 with respect to the first curved surface 373, it is possible to prevent the air supply device 100 from easily falling off from the mounting portion 520 in the axial direction.

[0136] In addition, at this time, the protruding wall portion 522 has two openings 525 and 526. The opening 525 is arranged at the same circumferential position as the switch portion 105 and the connector 51. They are exposed to the outside of the housing 3 through the opening 525. However, this example is not limited to the protruding wall portion 522, and the protruding wall portion 522 may also have an opening that is arranged at the same circumferential position as the connector 51 differently from the opening 525. The connector 51 can be exposed to the outside of the housing 3 through the opening. In this way, even after the air supply device 100 is assembled to the clothing accessory 500, the switch portion 105 can be manually operated. In addition, the terminal can be connected to the connector 51. However, this example does not exclude a structure in which the connector 51 is not exposed to the outside of the housing 3 after the air supply device 100 is assembled relative to the clothing accessory 500.

[0137] In addition, the opening 526 is arranged at the same circumferential position as the radial outer end of the airflow passage 362. Therefore, the exhaust port 321 is connected to the outside of the housing 3 through the airflow passage 362 and the opening 526. That is, even after the air supply device 100 is assembled on the clothing accessory 500, it is possible to send air to the outside of the housing 3 through the exhaust port 321, the airflow passage 362 and the opening 526.

[0138] Or, if Figure 8B As shown in FIG. 1 , the covering portion 523 and the protruding wall portion 522 may be arranged in a plurality at intervals in the circumferential direction. In other words, the contact of the covering portion 523 with the first curved surface 373 may be arranged in a plurality at intervals along the radial outer side surface of the housing 3. In addition, in this case, the protruding wall portion 522 may be arranged as shown in FIG. Figure 8B In this way, a plurality of covers 523 may be arranged at intervals in the circumferential direction, or a plurality of covers 523 may be arranged at intervals in the circumferential direction. Preferably, each cover 523 is arranged in a manner so that the air supply device 100 does not fall off from the mounting portion 520 in a direction parallel to the fabric 510 (radial direction). For example, when viewed from the axial direction, the cover 523 (i.e., the above-mentioned snap-fit ​​structure) is arranged at three or more locations in the radial outer end portion of the housing 3 that are dispersed to such an extent that the air supply device 100 does not fall off from the mounting portion 520. Figure 8B In the embodiment, the cover portion 523 (i.e., the above-mentioned engagement structure) is arranged on the left and right sides and the upper and lower sides of the radial outer end of the housing 3. In this way, by fitting the air supply device 100 to the mounting portion 520 on the clothing decoration 500 side, the air supply device 100 can be easily mounted on the clothing decoration 500. Moreover, by contacting the cover portion 523 with respect to the first curved surface 373, the air supply device 100 can be prevented from easily falling off from the mounting portion 520 in the axial direction.

[0139] In addition, at this time, it is preferred that the protruding wall portion 522 is arranged at a circumferential position different from at least one of the switch portion 105, the connector 51, and the radial outer end of the airflow passage 362. That is, the protruding wall portion 522 is arranged in a manner not to overlap with at least one of them. Alternatively, it may be arranged at the same position as the switch portion 105, the connector 51, and the radial outer end of the airflow passage 362. Fig. 8A Similarly, at least one of the openings 525 and 526 (and the opening for the connector 51) is formed in the protruding wall portion 522. Thus, the manual operation of the switch portion 105, the connection at the connector 51, and the delivery of the airflow can be performed without being affected by the arrangement of the protruding wall portion 522.

[0140] Then, as mentioned above, in Fig. 8A and Figure 8B In the example of , the switching member 1051 of the switch unit 105 is exposed outside the mounting portion 520. Thus, the switch unit 105 can be manually turned on / off. However, the present invention is not limited to the above example, and the switching member 1051 of the switch unit 105 may not be exposed outside the mounting portion 520.

[0141] <1-3. Another application example of the air supply device 100>

[0142] Fig.9A This is an enlarged view showing an assembly example of the air supply device 100 according to another application example, viewed from the inside of the clothing accessory 500 . Fig. 9B 1 is an enlarged view showing another assembly example of the air supply device 100 of another application example as viewed from the inside of the clothing accessory 500. Fig.9A and Fig. 9B The air supply device 100 is viewed from the axially other direction D2 toward the axially one direction D1 .

[0143] The following is about Fig. 8A and Figure 8B In addition, the same reference numerals are sometimes used to denote the same components as those in the above-mentioned application examples, and the description thereof is omitted.

[0144] exist Fig.9A and Fig. 9B In the embodiment, when the air supply device 100 is mounted on the clothing accessory 500, the switch unit 105 implements the power supply from the battery 103. That is, when the air supply device 100 is mounted, the power is supplied from the battery 103 to the air supply device 100 and the motor 101, so that the air supply device 100 and the motor 101 are driven. On the other hand, when the air supply device 100 is removed from the clothing accessory 500, the switch unit 105 stops the power supply from the battery 103. That is, when the air supply device 100 is removed, the power is not supplied from the battery 103 to the air supply device 100 and the motor 101, and the air supply device 100 and the motor 101 are stopped.

[0145] In this way, the driving and stopping of the air supply device 100 can be switched according to the loading and unloading of the air supply device 100 relative to the clothing decoration 500. In particular, the driving of the air supply device 100 and the motor 101 can be stopped without manual operation (knocking on the air supply device 100, disconnection operation of the switch part 105, etc.) only by removing the air supply device 100 from the clothing decoration 500. Therefore, it is possible to prevent the user from forgetting to set the driving (including the standby state) of the air supply device 100 to be disconnected when the air supply device 100 is not in use. Therefore, the power consumption of the air supply device 100 can be reduced, and the consumption of standby power can also be suppressed. Therefore, the driving time of the air supply device 100 and the motor 101 that can be used through a single charge can be further extended.

[0146] In addition, simply by attaching the air supply device 100 to the clothing accessory 500, the air supply device 100 and the motor 101 can be immediately driven without requiring manual operation (such as striking the air supply device 100 or turning on the switch 105).

[0147] For example, the switch portion 105 is a normally closed push button switch. The switch portion 105 has a switching member 1051. When the air supply device 100 is mounted on the clothing accessory 500, the switching member 1051 abuts against the protruding wall portion 522 disposed on the clothing accessory 500. In addition, the protruding wall portion 522 is an example of the "abutting portion" of the present invention.

[0148] exist Fig.9A and 9B In FIG. 1 , the switching component 1051 is a button of a push button switch. Fig.9A In the embodiment, the covering portion 523 and the protruding wall portion 522 of the mounting portion 520 extend in a ring shape over the entire circumferential area. In addition, the opening 525 (see Fig. 8A ). In addition, Fig. 9B In the embodiment, the covering portion 523 and the protruding wall portion 522 of the mounting portion 520 are arranged in a plurality of spaces in the circumferential direction. Fig.9A and Fig. 9B In the embodiment, when the air supply device 100 is mounted on the clothing accessory 500, the protruding wall portion 522 abuts against the switching member 1051 of the switch portion 105, and the switching member 1051 is pressed into the interior of the housing 3. That is, when the switching member 1051 abuts against the protruding wall portion 522, power is supplied from the battery 103. That is, power is supplied from the battery 103 to the air supply device 100 and the motor 101, so that the air supply device 100 and the motor 101 can be driven.

[0149] On the other hand, when the air supply device 100 is removed from the clothing accessory 500, the switching member 1051 protrudes from the inside of the housing 3 to the outside due to the release of the abutment. That is, when the abutment between the switching member 1051 and the protruding wall portion 522 is released, the power supply of the battery 103 is stopped. That is, the air supply device 100 and the motor 101 are not supplied with power from the battery 103, so the air supply device 100 and the motor 110 are stopped.

[0150] In this way, the driving (including the standby state) and stopping of the air supply device 100 and the motor 101 can be switched more easily according to the attachment and detachment of the air supply device 100 to the clothing accessory 500.

[0151] In addition, the switch unit 105 is not limited to the above example, and the switch unit 105 may be a switch device other than a push button switch. The switch unit 105 can be a switch device that can switch on and off according to the loading and unloading of the air supply device 100 relative to the clothing decoration 500 (for example, the presence or absence of the abutment between the protruding wall portion 522 and the switching member 1051).

[0152] In addition, not limited to the above application examples, the clothing decoration 500 may also be clothing other than tops (e.g., bottoms), or may be mounted on an item that can be mounted on the user's body. For example, the clothing decoration 500 may be mounted on head ornaments such as hats and helmets. That is, the clothing decoration 500 may be any one of clothing, footwear, head ornaments, etc. In this way, the temperature, humidity, etc. inside the clothing, footwear, head ornaments, etc., can be suppressed or prevented from rising. Therefore, their internal environment can be kept comfortable.

The present invention can be implemented by applying various changes to the above embodiments without departing from the scope of the main purpose of the invention. In addition, the matters described in the above embodiments can be appropriately combined in any manner within the scope that does not cause contradictions.

[0155] For example, the above-mentioned embodiments do not exclude that the air supply device 100 may be a structure other than a centrifugal fan. For example, the air supply device 100 may also be an axial flow fan.
