Also, note that the materials, shapes, dimensions, numbers, and arrangements of the components in each aspect of the examples and design variations described below are merely examples, and that any design variation is possible as long as the same functions can be achieved. [Example]

[0011] Hereinafter, a portable blower D1 according to multiple embodiments of the present invention, including a first embodiment and its design variations, will be described with reference to FIGS. 1A to 5. FIGS. 1A to 4 show the portable blower D1 of the first embodiment. FIG. 5 shows a design variation of the portable blower D1 of the first embodiment. FIGS. 1A, 1B, E, 1F, 4, and 5 show the Z-Z' direction. The Z-Z' direction includes the Z direction and the Z' direction. FIGS. 1A to 1D show the X-X' direction. The X-X' direction is substantially perpendicular to the Z-Z' direction and includes the X direction and the X' direction. FIGS. 1C to 1F, 4, and 5 show the Y-Y' direction. The Y-Y' direction is substantially perpendicular to the Z-Z' direction and the X-X' direction and includes the Y direction and the Y' direction.

[0012] The portable blower D1 includes a main body 100. The main body 100 has an upper portion 110, a lower portion 120, and a tubular portion .

[0013] The upper portion 110 and the lower portion 120 may be substantially polygonal or circular, and may be made of a flexible fabric made of at least one of nylon, vinyl, and polyester, or other flexible fabric, a flexible high-density woven fabric with threads woven at a high density, or other fabric, or a combination of such fabrics and fabrics. Note that one or both sides of the fabric or fabric may be coated or laminated with a resin film such as polyurethane resin (e.g., thermoplastic polyurethane (TPU)), polyester resin, or polytetrafluoroethylene resin, or may be treated with PVC (polyvinyl chloride), but this is not limitative.

[0014] The upper portion 110 is the portion of the main body portion 100 on the Z-Z' direction side. The lower portion 120 is the portion of the main body portion 100 on the Z' direction side. The upper portion 110 and the lower portion 120 face each other in the Z-Z' direction. The upper portion 110 may be inclined in a first oblique direction (not shown) including components in the Y direction and the Z' direction, or in a second oblique direction including components in the Y' direction and the Z' direction (see Figures 1A to 4), but it does not have to be inclined. The Z-Z' direction is the direction in which the upper portion 110 and the lower portion 120 face each other.

[0015] The tubular portion 130 is a generally polygonal tube or a generally cylindrical tube extending in the Z-Z' direction from the peripheral edge of the upper portion 110 to the peripheral edge of the lower portion 120, and may be made of the above-mentioned flexible fabric, flexible woven fabric (including high-density woven fabric), or a combination of such fabric and high-density woven fabric. The tubular portion 130 may be provided with a linear fastener F. The linear fastener F extends in a generally U-shaped or O-shaped manner in the circumferential direction of the tubular portion 130. When the linear fastener F is closed, the upper portion of the tubular portion 130 and the lower portion of the tubular portion 130 are connected to form the tubular portion 130. When the linear fastener F is open, the upper portion of the tubular portion 130 on the Z-direction side and the lower portion of the tubular portion 130 on the Z'-direction side are partially or completely separated.

[0016] The line fasteners F may be provided on the upper portion 110 or the lower portion 120 instead of the tubular portion 130, or may be provided on the connecting portion between the outer periphery of the upper portion 110 and the tubular portion 130 or the connecting portion between the outer periphery of the lower portion 120 and the tubular portion 130. The line fasteners F may be omitted. In this case, the upper portion 110 or the lower portion 120 may be a lid connected to the tubular portion 130 that can be opened and closed freely.

[0017] The cylindrical portion 130 has a first portion 131 on the Y direction side, a second portion 132 on the Y' direction side, a third portion 133 on the X direction side, and a fourth portion 134 on the X' direction side.

[0018] The main body 100 further has an exhaust part EX and an intake part IN (ventilation part).

[0019] The exhaust section EX is provided in any one of the upper portion 110, the first portion 131 of the cylindrical portion 130, the second portion 132 of the cylindrical portion 130, the third portion 133 of the cylindrical portion 130, and the fourth portion 134 of the cylindrical portion 130.

[0020] The exhaust section EX has one or more first openings EX1 (exhaust ports) and one or more edge portions of the first openings EX1. The exhaust section EX may further have a mesh sheet arranged to cover one or more first openings EX1, but this is not essential. The one or more first openings EX1 are provided in any one of the upper portion 110 (see FIGS. 1A to 5), the first portion 131 (not shown) of the tubular portion 130, the second portion 132 (not shown) of the tubular portion 130, the third portion 133 (not shown) of the tubular portion 130, and the fourth portion 134 (not shown) of the tubular portion 130.

[0021] When the multiple first openings EX1 are provided in the upper portion 110 inclined in the first or second inclination direction, the multiple first openings EX1 may extend in the first or second inclination direction, and the dimension of each of the multiple first openings EX1 in the X-X' direction may gradually increase from the Z direction side (upper side in the figure) to the Z' direction side (lower side in the figure) of each of the multiple first openings EX1 (see FIG. 1C). However, the shape of the multiple first openings EX1 may be set arbitrarily. The multiple first openings EX1 may be arranged at intervals in the X-X' direction (see FIGS. 1A to 3), or may be arranged in a matrix (not shown), but may be arranged arbitrarily. The X-X' direction is approximately perpendicular to the first or second inclination direction.

[0022] The intake section IN has one or more second openings IN1 and one or more edge portions of the second openings IN1. Note that in this embodiment, for the sole purpose of distinguishing between the one or more second openings IN1 of the intake section IN and the one or more first openings EX1 of the exhaust section EX, the one or more openings of the exhaust section EX are referred to as "one or more first openings" and the one or more openings of the intake section IN are referred to as "one or more second openings."

[0023] The main body 100 may further have a mounting hole 140 (see FIGS. 1A to 3). The mounting hole 140 penetrates one of the upper portion 110 (not shown), the lower portion 120 (not shown), the first portion 131 (see FIGS. 1A to 3) of the tubular portion 130, the second portion 132 (not shown) of the tubular portion 130, the third portion 133 (not shown) of the tubular portion 130, and the fourth portion 134 (not shown) of the tubular portion 130. The mounting hole 140 is positioned so as not to interfere with the exhaust portion EX.

[0024] Portable blower D1 further includes fan 200. Fan 200 may be, but is not limited to, an axial fan, a centrifugal fan, or a sirocco fan. Fan 200 includes a housing 210, a blade portion 220, and a motor (not shown).

[0025] The fan 200 may be fixed to the edge of the mounting hole 140 of the main body 100. In this case, the fan 200 may have the following configuration.

[0026] The housing 210 has, for example, a cylindrical portion 211, an outer guard portion 212 (exposed portion), an inner guard portion 213, and a flange 214.

[0027] The outer diameter of the cylindrical portion 211 is approximately the same as or slightly smaller than the diameter of the mounting hole 140 of the main body portion 100. The cylindrical portion 211 is inserted into the mounting hole 140 of the main body portion 100 from the outside of the main body portion 100 and is disposed inside the main body portion 100. A threaded portion (not shown) is formed on the outer circumferential surface of the cylindrical portion 211.

[0028] The flange 214 is generally annular and extends from the outer peripheral surface of the cylindrical portion 211 , and abuts against the periphery of the mounting hole 140 from the outside of the main body portion 100 .

[0029] The outer guard portion 212 is a lattice formed to close the outer opening of the cylindrical portion 211, and is exposed to the outside of the main body portion 100 through the mounting hole 140. In this way, the outer guard portion 212 is exposed from the mounting hole 140 and forms the intake portion IN of the main body portion 100. The multiple openings between the lattices of the outer guard portion 212 of the housing 210 become the multiple second openings IN1 of the intake portion IN, and the lattice of the outer guard portion 212 of the housing 210 becomes the edge of the multiple second openings IN1 of the intake portion IN. In this case, the shape of the multiple second openings IN1 can be set as desired.

[0030] The inner guard portion 213 is a lattice formed to close the opening on the inside of the cylindrical portion 211, and has multiple openings. The inner guard portion 213 is disposed inside the main body portion 100. The multiple openings of the inner guard portion 213 communicate with the inside of the main body portion 100.

[0031] The blade portion 220 and the motor are held in an accommodation space of the housing 210, which is defined by the cylindrical portion 211, the outer guard portion 212, and the inner guard portion 213 of the housing 210. The blade portion 220 is connected to the rotating shaft of the motor directly or indirectly via a gear or the like within the accommodation space, and is rotatable.

[0032] Fan 200 further includes fixing device 230. Fixing device 230 is a cylinder with a thread formed on its inner circumferential surface, and is screwed onto cylindrical portion 211 of housing 210 inside main body 100 and abuts against the periphery of mounting hole 140 from the inside of main body 100. In this way, the periphery of mounting hole 140 is sandwiched between flange 214 and fixing device 230, thereby fixing fan 200 to the periphery of mounting hole 140.

[0033] The fan 200 may be configured to be housed within the main body 100 rather than being fixed to the edge of the mounting hole 140 of the main body 100 (see FIG. 4). In this case, the mounting hole 140 is omitted, and the intake section IN is provided in any one of the upper section 110 (not shown), the lower section 120 (not shown), the first section 131 of the tubular section 130 (see FIG. 4), the second section 132 of the tubular section 130 (not shown), the third section 133 of the tubular section 130 (not shown), and the fourth section 134 of the tubular section 130 (not shown). The one or more second openings IN1 of the intake section IN are provided in any one of the upper section 110 (not shown), the lower section 120 (not shown), the first section 131 of the tubular section 130 (see FIG. 4), the second section 132 of the tubular section 130 (not shown), the third section 133 of the tubular section 130 (not shown), and the fourth section 134 of the tubular section 130 (not shown). The one or more second openings IN1 of the intake section IN are arranged so as not to interfere with the exhaust section EX. The shape of the multiple second openings IN1 can be set arbitrarily. The intake section IN may further include a mesh sheet provided to cover the one or more second openings IN1, but this is not essential. The flange 214 and the fixture 230 of the fan 200 may be omitted.

[0034] In either case, when fan 200 is fixed to the edge of mounting hole 140 of main body 100 or when fan 200 is housed within main body 100, the motor of fan 200 is driven and blades 220 rotate, thereby drawing air into main body 100 from intake port IN and expelling it from exhaust port EX. The motor is turned on and off by a switch.

[0035] Portable blower D1 further includes cover 300. Cover 300 faces at least partly toward intake portion IN and is flexible and / or displaceable toward intake portion IN. For example, cover 300 may further include any one of the following configurations (1) to (4).

[0051] (2-3-2) A first edge of cover 300 is connected (for example, by bonding or sewing) to a portion of upper portion 110 or lower portion 120 on the X-direction side or X'-direction side of intake portion IN. A third edge of cover 300 is connected (for example, by bonding or sewing) to a portion of upper portion 110 or lower portion 120 on the Y-direction side of intake portion IN, and a fourth edge of cover 300 is connected (for example, by bonding or sewing) to a portion of upper portion 110 or lower portion 120 on the Y'-direction side of intake portion IN. With the first, second, and third edges of cover 300 connected in this manner, the central portion of cover 300 is curved in an arc shape convex in the direction away from intake portion IN or is bent so as to be convex in the direction away from intake portion IN, so that cover 300 at least partially faces intake portion IN and is open in the X'-direction or X-direction.

[0052] (2-4) When the outer guard portion 212 of the fan 200 is exposed from the mounting hole 140 provided in the upper portion 110 or the lower portion 120 to form the intake portion IN, or when the intake portion IN is provided in the upper portion 110 or the lower portion 120, and the cover 300 is an approximately semicircular or approximately semi-elliptical sheet, the cover 300 has the following configuration (2-4-1) or (2-4-2).

[0053] (2-4-1) The first edge of cover 300 is a substantially semicircular arc, a substantially circular arc, or a substantially U-shaped arc that convex toward the Y direction or the Y' direction. The first edge of cover 300 is connected (for example, by adhesive or sewing) to the Y direction or Y' direction side portion, the X direction side portion, and the X' direction side portion of upper side portion 110 or lower side portion 120 relative to intake portion IN. With the first edge of cover 300 connected in this manner, the central portion of cover 300 is curved in a convex arc shape in the direction away from intake portion IN or is bent so as to be convex in the direction away from intake portion IN, so that cover 300 at least partially faces intake portion IN and is open in the Y' direction or Y direction.

[0054] (2-4-2) The first edge of cover 300 is a generally semicircular, arc, or U-shaped convex toward the X or X' direction. The first edge of cover 300 is connected (for example, by adhesive or sewing) to the X or X' direction side portion, the Y direction side portion, and the Y' direction side portion of upper portion 110 or lower portion 120 relative to intake portion IN. With the first edge of cover 300 connected in this manner, the central portion of cover 300 is curved in a convex arc shape in the direction away from intake portion IN or is bent so as to be convex in the direction away from intake portion IN, so that cover 300 at least partially faces intake portion IN and is open in the X' or X direction.

[0055] (3) The cover 300 of (1-1) or (1-2) above may be a hood made of an elastic material such as rubber or urethane foam, rather than being made of the flexible fabric, textile, or a combination thereof. The opposing portion 310, the first side wall portion 320, and the second side wall portion 320 of the cover 300 are configured as in (1-1) or (1-2) above, except that they are integrally made of the elastic material.

[0056] (4) The cover 300 of any of the above (2-1) to (2-4) may be configured not from the sheet described above, but may be a hood made of an elastic material such as rubber or urethane foam configured as described in any of the above (2-1) to (2-4). The cover 300 is a hood that is produced / molded so that its central portion is curved in a convex arc shape in a direction away from the intake portion IN or bent so as to be convex in a direction away from the intake portion IN, and has the same configuration as described in (2-1) or (2-2) above, except that the cover 300 faces at least partly the intake portion IN and is open in the Z' direction. Alternatively, the cover 300 is a hood that is manufactured / shaped so that its central portion is curved in an arc shape that is convex in the direction away from the intake portion IN or bent so as to be convex in the direction away from the intake portion IN, and has the configuration as described in (2-3-1) or (2-4-1) above, except that the cover 300 faces the intake portion IN at least partially and the cover 300 is open in the Y' direction or the Y direction. Alternatively, the cover 300 is a hood that is manufactured / shaped so that its central portion is curved in an arc shape that is convex in the direction away from the intake portion IN or bent so as to be convex in the direction away from the intake portion IN, and has the configuration as described in (2-3-2) or (2-4-2) above, except that the cover 300 faces the intake portion IN at least partially and the cover 300 is open in the X' direction or the X direction.

[0057] Portable blower D1 further includes support part 400. Support part 400 is disposed between intake part IN and cover 300, and when cover 300 is bent and / or displaced a predetermined amount toward intake part IN, support part 400 is interposed between intake part IN and cover 300 to prevent cover 300 from bending and / or displacing more than the predetermined amount toward intake part IN.

[0058] The support part 400 may be provided on either the intake part IN or the cover 300 and disposed at a distance from the other, and may be configured so that when the cover 300 is bent and / or displaced a predetermined amount toward the intake part IN side, the support part 400 abuts against the other to prevent the cover 300 from bending and / or displacing more than the predetermined amount toward the intake part IN side. More specifically, the support part 400 has one of the following configurations (a) to (e).

[0059] (a) The support portion 400 has a pair of standing portions 410 and a connecting portion 420.

[0060] The pair of upright portions 410 are made of flexible fabric made of at least one of nylon, vinyl, and polyester, or other flexible fabric, flexible high-density woven fabric with densely woven threads, or other flexible fabric, or a combination of such fabrics and fabrics. One or both sides of the fabric or fabric may be coated or laminated with a resin film such as polyurethane resin (e.g., thermoplastic polyurethane (TPU)), polyester resin, or polytetrafluoroethylene resin, or may be treated with PVC (polyvinyl chloride), but this is not limiting. The pair of upright portions 410 extend from the cover 300 toward the intake section IN and approach each other. The pair of upright portions 410 may be flat (see FIGS. 1A to 5), or may curve toward the intake section IN and extend toward each other (not shown). The pair of upright portions 410 have a base and a tip on the opposite side. The bases of the pair of upstanding portions 410 are connected to the cover 300 (for example, by adhesion, sewing, etc.).

[0061] The connecting portion 420 connects the tip ends of the pair of standing portions 410. Like the pair of standing portions 410, the connecting portion 420 may be made of the above-mentioned flexible fabric, flexible woven fabric, or a combination thereof, but the connecting portion 420 may be made of any material as long as it can connect the tip ends of the pair of standing portions 410. The thickness dimension of the connecting portion 420 may be smaller than the thickness dimension of each of the pair of standing portions 410, but can also be approximately the same as or larger than that. The connecting portion 420 is arranged with a gap between them and the intake portion IN.

[0062] In the support part 400 configured as described above, the connecting part 420 abuts against the edge of one or more second openings IN1 of the intake part IN when the cover 300 is bent and / or displaced a predetermined amount toward the intake part IN. When the connecting part 420 of the support part 400 abuts against the edge of one or more second openings IN1 of the intake part IN, the support part 400 may be crushed between the cover 300 and the intake part IN, causing it to flex or elastically deform slightly. Even in this case, the support part 400 is interposed between the intake part IN and the cover 300, preventing the cover 300 from bending and / or displacing more than a predetermined amount toward the intake part IN. Note that the support part 400 may not be configured to flex or elastically deform.

[0063] A ventilation space S is defined by the pair of upright portions 410 and connecting portion 420 of the support portion 400, and the cover 300. This ventilation space S communicates with one or more second openings IN1 of the intake portion IN, and is open in the same direction as the cover 300. Air outside the portable blower D1 is drawn in through the ventilation space S and from one or more second openings IN1 of the intake portion IN.

[0064] (b) The support part 400 has the same configuration as the support part 400 of (a) above, except that it does not have the connecting part 420. The tip ends of the pair of upright parts 410 may be free ends or may be connected to each other. In either case, the tip ends of the pair of upright parts 410 are arranged with a gap between them and the intake part IN. In the support part 400 configured as described above, when the cover 300 is bent and / or displaced a predetermined amount toward the intake part IN, the tip ends of the pair of upright parts 410 abut against the edge of one or more second openings IN1 of the intake part IN. When the tip ends of the pair of upright parts 410 of the support part 400 abut against the edge of one or more second openings IN1 of the intake part IN, the pair of upright parts 410 may be crushed between the cover 300 and the intake part IN, causing slight flexibility or elastic deformation. Even in this case, the pair of standing portions 410 are interposed between the intake portion IN and the cover 300, and can prevent the cover 300 from bending and / or displacing more than a predetermined amount toward the intake portion IN side. Note that the support portion 400 may be configured not to be flexible or elastically deformable.

[0065] A ventilation space (not shown) is defined by the pair of upright portions 410 of the support portion 400 and the cover 300. This ventilation space communicates with one or more second openings IN1 of the intake portion IN and opens in the same direction as the cover 300. Air outside the portable blower D1 is drawn in through the ventilation space and from one or more second openings IN1 of the intake portion IN.

[0066] (c) The support part 400 has the same configuration as the support part 400 of (a) above, except that the pair of upright parts 410 of (a) above extend from the intake part IN or a portion of the main body part 100 around the intake part IN toward the cover 300 and approach each other, and the connecting part 420 of (a) above is disposed at a distance from the cover 300. The connecting part 420 abuts against the cover 300 when the cover 300 is bent and / or displaced a predetermined amount toward the intake part IN. When the connecting part 420 of the support part 400 abuts against the cover 300, the support part 400 may be crushed between the cover 300 and the intake part IN, causing it to be slightly flexible or elastically deformed. Even in this case, the support part 400 is interposed between the intake part IN and the cover 300, preventing the cover 300 from bending and / or displacing more than a predetermined amount toward the intake part IN. The support portion 400 may be configured not to be flexible or elastically deformable.

[0067] A ventilation space (not shown) is defined by the pair of upright portions 410 and the connecting portion 420 of the support portion 400. This ventilation space communicates with one or more second openings IN1 of the intake portion IN and opens in the same direction as the cover 300. Air outside the portable blower D1 is drawn in through the ventilation space and from one or more second openings IN1 of the intake portion IN.

[0068] The support part 400 (d) has the same configuration as the support part 400 (b) above, except that the pair of standing parts 410 (b) above extend from the intake part IN or a part of the main body part 100 around the intake part IN toward the cover 300 and so as to approach each other, and the tips of the pair of standing parts 410 are arranged with a gap between them. When the cover 300 is in a state where it is bent and / or displaced a predetermined amount toward the intake part IN, the tips of the pair of standing parts 410 abut against the cover 300. When the tips of the pair of standing parts 410 of the support part 400 abut against the cover 300, the pair of standing parts 410 may be crushed between the cover 300 and the intake part IN, and may be slightly flexible or elastically deformed. Even in this case, the pair of standing portions 410 are interposed between the intake portion IN and the cover 300, and can prevent the cover 300 from bending and / or displacing more than a predetermined amount toward the intake portion IN side. Note that the support portion 400 may be configured not to be flexible or elastically deformable.

[0069] A ventilation space (not shown) is defined by a pair of upright portions 410 of the support portion 400. This ventilation space communicates with one or more second openings IN1 of the intake portion IN and opens in the same direction as the cover 300. Air outside the portable blower D1 is drawn in through the ventilation space and from one or more second openings IN1 of the intake portion IN.

[0070] (e) The support portion 400 has one or more protrusions extending from either the intake portion IN or the cover 300 to the other, and the one or more protrusions are arranged at intervals relative to the other, so that when the cover 300 is bent and / or displaced a predetermined amount toward the intake portion IN, the one or more protrusions of the support portion 400 come into contact with the other, preventing the cover 300 from bending and / or displacing more than the predetermined amount toward the intake portion IN. The one or more protrusions may be made of an elastic material such as resin, rubber, urethane foam, or a spring, or, like the pair of standing portions 410, may be made of the flexible fabric or flexible woven material described above, or a combination thereof.

[0071] A ventilation space (not shown) is defined by the cover 300. This ventilation space communicates with one or more second openings IN1 of the intake unit IN and opens in the same direction as the cover 300. Air outside the portable blower D1 is drawn in through the ventilation space and from one or more second openings IN1 of the intake unit IN.

[0072] In addition, one or more protrusions may be an elastic body such as rubber, urethane foam, or a spring interposed between the intake section IN and the cover 300, and may be configured to elastically deform a predetermined amount when the cover 300 flexes and / or displaces toward the intake section IN by a predetermined amount, but not to elastically deform beyond that predetermined amount.

[0073] The support parts 400 (a) to (d) described above may be made of an elastic material such as rubber, urethane foam, spring, etc. Also, the support parts 400 described above may be configured not to be flexible or elastically deformable.

[0074] Portable blower D1 may further include a wearing means for wearing portable blower D1 on the human body, which includes at least one of a strap ST, one or more belt loops B1, and one or more armbands (not shown).

[0075] The strap ST is a looped string extending from the main body 100. By hanging the strap ST around the neck of a person, the portable blower D1 is suspended from the body. In this suspended state, the main body 100 should be positioned so that the exhaust part EX faces the body.

[0076] Each of the one or more belt loops B1 has a first end on one side in the longitudinal direction and a second end on the other side in the longitudinal direction. The first end of each of the one or more belt loops B1 is permanently connected to one of the first portion 131, the second portion 132, the third portion 133, and the fourth portion 134 of the tubular portion 130 of the main body 100. The second end of each of the one or more belt loops B1 is detachably or permanently connected to one of the first portion 131, the second portion 132, the third portion 133, and the fourth portion 134 of the tubular portion 130 of the main body 100 at a position on the Z'-direction side or the Z-direction side of the first end of each of the one or more belt loops B1. The portable blower D1 is worn around the waist of a person by passing a belt through the one or more belt loops B1. In this worn state, the exhaust portion EX should face the person's body.

[0077] The one or more armbands have a first end on one side in the longitudinal direction and a second end on the same side in the longitudinal direction. The first end of the one or more armbands is permanently connected to one of the first section 131, second section 132, third section 133, and fourth section 134 of the tubular section 130 of the main body 100. The second end of the one or more armbands is detachably or permanently connected to one of the first section 131, second section 132, third section 133, and fourth section 134 of the tubular section 130 of the main body 100 at a position on the X-direction side, the X'-direction side, the Y-direction side, or the Y'-direction side of the first end of the one or more armbands. The portable blower D1 is worn on a human arm by passing the arm through the one or more armbands. The arm may be moved to direct the exhaust section EX toward the human body.

[0078] Portable blower D1 may further include an external pocket OP. The external pocket OP is provided in any one of first portion 131, second portion 132, third portion 133, and fourth portion 134 of tubular portion 130 of main body 100, and is open to the Z direction side.

[0079] The portable blower D1 may further include a battery 500. The battery 500 is electrically connected to the fan 200, thereby supplying power to the motor of the fan 200. The battery 500 may be housed and held in an external pocket OP, or may be housed within the main body 100. In the latter case, the battery 500 can be housed within the main body 100 by opening the fastener F, and the external pocket OP may be omitted. There may be multiple batteries 500, or the battery 500 may be omitted. If omitted, an external battery may be used to drive at least one fan 200.

[0080] The portable blower D1 may further include one or more mounting bands B2. The one or more mounting bands B2 have a first end on one side in the longitudinal direction and a second end on the same side in the longitudinal direction. The first end of the one or more mounting bands B2 is non-detachably connected to one of the first portion 131, second portion 132, third portion 133, and fourth portion 134 of the tubular portion 130 of the main body 100 on the Z-direction side relative to the external pocket OP. The second end of the one or more mounting bands B2 is detachably connected to the external pocket OP. With the second end of the one or more mounting bands B2 connected to the external pocket OP, the one or more mounting bands B2 and the external pocket OP hold the battery 500 housed in the external pocket OP. Note that one or more mounting bands B2 may be omitted.

[0081] The portable fan D1 as described above has the following technical features and effects (1) to (8).

[0082] (1) Since the cover 300 is flexible and / or displaced by a predetermined amount toward the intake portion IN, even if the cover 300 hits a human body or an object, the portable blower D1 does not hit the human body or object softly.

[0083] (2) When cover 300 is bent and / or displaced a predetermined amount toward intake section IN, support section 400 is interposed between intake section IN and cover 300 to prevent cover 300 from bending and / or displacing more than the predetermined amount toward intake section IN, so intake section IN is not blocked by cover 300 bending and / or displacing toward intake section IN. Because intake section IN is not blocked by cover 300 in this way, it is possible to use portable blower D1 by placing cover 300 facing the body while hanging it around the neck with strap ST.

[0084] (3) When the support portion 400 extends from either the intake portion IN or the cover 300 to the other and is disposed at a distance from the other, the support portion 400 abuts against the other when the cover 300 is bent and / or displaced a predetermined amount toward the intake portion IN. With this simple configuration, the portable blower D1 can prevent the cover 300 from bending and / or displacing more than a predetermined amount toward the intake portion IN.

[0085] (4) When the support part 400 has the configuration (a) described above, the support part 400 has a pair of standing parts 410 and a connecting part 420, and therefore the connecting part 420 of the support part 400 abuts against the intake part IN when the cover 300 is bent and / or displaced a predetermined amount toward the intake part IN. At this time, the pair of standing parts 410 and the connecting part 420 are interposed between the intake part IN and the cover 300, making the support part 400 less likely to be crushed. Furthermore, the support part 400 and the cover 300 define an air vent space S. Since the support part 400 is not present in the space outside (on both sides of) the pair of standing parts 410 in this air vent space S, the presence of the support part 400 makes it less likely that the intake of air into the intake part IN through the air vent space S will be obstructed. When the support part 400 has the configuration (b) above, the support part 400 has a pair of standing parts 410, and therefore the pair of standing parts 410 of the support part 400 abuts against the intake part IN when the cover 300 is bent and / or displaced a predetermined amount toward the intake part IN. At this time, the pair of standing parts 410 support the cover 300, making the support part 400 less likely to be crushed. Moreover, a ventilation space is defined by the pair of standing parts 410 and the cover 300. Since the support part 400 is not present in the space outside (on both sides of) the pair of standing parts 410 in this ventilation space, the presence of the support part 400 makes it less likely that the intake of air into the intake part IN through the ventilation space will be obstructed. When the support part 400 has the configuration (c) above, the support part 400 has a pair of upright parts 410 and a connecting part 420, and therefore the connecting part 420 of the support part 400 abuts against the cover 300 when the cover 300 is bent and / or displaced a predetermined amount toward the intake part IN. At this time, the pair of upright parts 410 and the connecting part 420 are interposed between the intake part IN and the cover 300, making the support part 400 less likely to be crushed. Furthermore, the space within the pair of upright parts 410 and the connecting part 420 can be used as a ventilation space, making it less likely that the presence of the support part 400 will obstruct the intake of air into the intake part IN through the ventilation space. When the support part 400 has the configuration (d) above, the support part 400 has a pair of upright parts 410, and therefore the pair of upright parts 410 abut against the cover 300 when the cover 300 is bent and / or displaced a predetermined amount toward the intake part IN. At this time, the pair of standing portions 410 and the connecting portion 420 are interposed between the intake portion IN and the cover 300, so that the support portion 400 is less likely to be crushed.Moreover, since the space within the pair of standing portions 410 can be used as a ventilation space, the presence of the support portion 400 is less likely to interfere with the intake of air by the intake portion IN through the ventilation space.

[0086] (5) If the support portion 400 is flexible or elastically deformable in accordance with the flexibility and / or displacement of the cover 300 toward the intake portion IN, the support portion 400 will be flexible or elastically deformable while interposed between the cover 300 and the intake portion IN, making the portable blower D1 even softer in contact with the human body or objects.

[0087] (6) If the cover and / or support of the portable blower were molded from resin, costs for creating a mold to fabricate the cover and / or support would be necessary, resulting in high production costs for the portable blower. However, if the cover 300 of the portable blower D1 were made of the flexible fabric, flexible textile, or a combination thereof, and the support 400 of the portable blower D1 were made of the flexible fabric, flexible textile, or a combination thereof, costs for creating a mold would be unnecessary, thereby significantly reducing the production costs of the portable blower D1.

[0088] (7) Since the main body 100 is made of a flexible material, the portable blower D1 comes into contact with the human body or other objects more gently.

[0089] (8) In a case where the upper portion 110 of the main body 100 is inclined in a first oblique direction, the exhaust portion EX has a plurality of first openings EX1 provided in the upper portion 110, and the plurality of first openings EX1 each extend in the first oblique direction and the dimension in the X-X′ direction of each of the plurality of first openings EX1 gradually increases from the Z direction side to the Z′ direction side of each of the plurality of first openings EX1, the small dimension in the X-X′ direction of the Z direction side of each of the plurality of first openings EX1 causes the wind speed of the air discharged at the Z direction side of each of the plurality of first openings EX1 to be fast, while the large dimension in the X-X′ direction of the Z′ direction side of each of the plurality of first openings EX1 causes the wind speed of the air discharged at the Z′ direction side of each of the plurality of first openings EX1 to be slow. As a result, air is more likely to be discharged from the plurality of first openings EX1 in a third oblique direction that includes components in the Z direction and the Y′ direction. For the same reason, even in a case where the upper part 110 of the main body 100 is inclined in the second oblique direction, the exhaust section EX has a plurality of first openings EX1 provided in the upper part 110, and the plurality of first openings EX1 each extend in the second oblique direction and the dimension of each of the plurality of first openings EX1 in the X-X' direction gradually increases from the Z direction side to the Z' direction side of each of the plurality of first openings EX1, air is more likely to be discharged from the plurality of first openings EX1 in the fourth oblique direction that includes components in the Z direction and the Y direction. For this reason, when the portable blower D1 is carried on a person's body with the upper part 110 of the main body 100 facing the person's body, it becomes easier to blow the air discharged from the exhaust section EX toward the person's body. [Example]

[0090] Portable blower D2 according to several embodiments of the present invention, including a second embodiment and its design variations, will be described below with reference to Figures 6 and 7. Figure 6 shows portable blower D2 according to the second embodiment. Figure 7 shows a design variation of portable blower D2 according to the second embodiment. In Figures 6 and 7, the Z-Z' direction and the Y-Y' direction are shown in the same way as in Figures 4 and 5. For the X-X' direction, reference will be made to Figures 1A to 1D.

[0091] Portable blower D2 has the same configuration as portable blower D1, except that cover 300 covers exhaust section EX (ventilation section) instead of intake section IN, and support section 400 is disposed between exhaust section EX and cover 300. Only these differences will be described in detail below, and explanations of portable blower D2 that overlap with those of portable blower D1 will be omitted.

[0092] When a mounting hole 140 is provided in any one of the upper portion 110 (not shown), the lower portion 120 (not shown), the first portion 131 (see Figure 6) of the tubular portion 130, the second portion 132 (not shown) of the tubular portion 130, the third portion 133 (not shown) of the tubular portion 130, and the fourth portion 134 (not shown) of the tubular portion 130, the fan 200 is fixed to the edge of the mounting hole 140 of the main body portion 100, and the outer guard portion 212 of the fan 200 is exposed from the mounting hole 140 to form the intake portion IN of the main body portion 100. An exhaust section EX is provided in any one of the upper section 110 (not shown), the lower section 120 (not shown), the first section 131 (not shown) of the tubular section 130, the second section 132 (see FIG. 7 ) of the tubular section 130, the third section 133 (not shown) of the tubular section 130, and the fourth section 134 (not shown) of the tubular section 130.

[0105] The support part 400 of the portable blower D2 is disposed between the exhaust part EX and the cover 300, and when the cover 300 is bent and / or displaced a predetermined amount toward the exhaust part EX, the support part 400 is interposed between the exhaust part EX and the cover 300 to prevent the cover 300 from bending and / or displacing more than the predetermined amount toward the exhaust part EX. The support part 400 may be provided on either the exhaust part EX or the cover 300 and disposed at a distance from the other, and when the cover 300 is bent and / or displaced a predetermined amount toward the exhaust part EX, the support part 400 may abut against the other to prevent the cover 300 from bending and / or displacing more than the predetermined amount toward the exhaust part EX.

[0106] When the support part 400 of the portable blower D2 has the above-mentioned configuration (a), the configuration is the same as that of the support part 400 of the portable blower D1 having the above-mentioned configuration (a), except that the pair of upright parts 410 of the support part 400 extend from the cover 300 toward the exhaust part EX and approach each other, and when the cover 300 is bent and / or displaced a predetermined amount toward the exhaust part EX, the connecting part 420 of the support part 400 abuts the edge of one or more first openings EX1 of the exhaust part EX.

[0107] A ventilation space (not shown) is defined by the pair of upright portions 410 and connecting portion 420 of support portion 400, and cover 300. This ventilation space communicates with one or more first openings EX1 of exhaust portion EX and is open in the same direction as cover 300. Air introduced into main body 100 of portable blower D2 from intake portion IN is discharged from the ventilation space through one or more second openings IN1 of exhaust portion EX.

[0108] When the support part 400 of the portable blower D2 has the configuration (b) above, the configuration is the same as that of the support part 400 of the portable blower D1 having the configuration (b) above, except that the pair of standing parts 410 of the support part 400 extend from the cover 300 toward the exhaust part EX and approach each other, and when the cover 300 is bent and / or displaced a predetermined amount toward the exhaust part EX, the tip parts of the pair of standing parts 410 abut against the edge part of one or more first openings EX1 of the exhaust part EX.

[0109] A ventilation space (not shown) is defined by the pair of upright portions 410 of the support portion 400 and the cover 300. This ventilation space communicates with one or more first openings EX1 of the exhaust portion EX and is open in the same direction as the cover 300. Air introduced into the main body 100 of the portable blower D2 from the intake portion IN is discharged from the ventilation space through one or more first openings EX1 of the exhaust portion EX.

[0110] When the support part 400 of the portable blower D2 has the above-mentioned configuration (c), the pair of standing parts 410 of the support part 400 have the same configuration as the support part 400 of the portable blower D1 having the above-mentioned configuration (c), except that they extend from the exhaust part EX or the part around the exhaust part EX of the main body part 100 toward the cover 300 and so as to approach each other.

[0111] A ventilation space (not shown) is defined by the pair of upright portions 410 and the connecting portion 420 of the support portion 400. This ventilation space communicates with one or more first openings EX1 of the exhaust portion EX and is open in the same direction as the cover 300. Air introduced into the main body 100 of the portable blower D2 from the intake portion IN is discharged from the ventilation space through one or more first openings EX1 of the exhaust portion EX.

[0112] When the support part 400 of the portable blower D2 has the configuration (d) above, the pair of standing parts 410 of the support part 400 have the same configuration as the support part 400 of the portable blower D1 having the configuration (d) above, except that they extend from the exhaust part EX or the part around the exhaust part EX of the main body part 100 toward the cover 300 and so as to approach each other.

[0113] A ventilation space (not shown) is defined by a pair of upright portions 410 of the support portion 400. This ventilation space communicates with one or more first openings EX1 of the exhaust portion EX and is open in the same direction as the cover 300. Air introduced into the main body 100 of the portable blower D2 from the intake portion IN is discharged from the ventilation space through one or more first openings EX1 of the exhaust portion EX.

[0114] When the support part 400 of the portable blower D2 has the configuration (e) above, one or more protrusions of the support part 400 extend from either the exhaust part EX or the cover 300 to the other, and the one or more protrusions are arranged at a distance from the other, so that when the cover 300 is bent and / or displaced a predetermined amount toward the exhaust part EX, the one or more protrusions of the support part 400 abut against the other to prevent the cover 300 from bending and / or displacing more than the predetermined amount toward the exhaust part EX, and the configuration is the same as that of the support part 400 of the portable blower D1 having the configuration (e) above.

[0115] A ventilation space (not shown) is defined by the cover 300. This ventilation space communicates with one or more first openings EX1 of the exhaust section EX and is open in the same direction as the cover 300. Air introduced into the main body 100 of the portable blower D2 from the intake section IN is discharged from the ventilation space through one or more first openings EX1 of the exhaust section EX.

[0116] In addition, one or more protrusions may be an elastic body such as rubber, urethane foam, or a spring interposed between the exhaust section EX and the cover 300, and may be configured to elastically deform a predetermined amount when the cover 300 flexes and / or displaces toward the exhaust section EX, but not to elastically deform beyond that predetermined amount.

[0117] The support parts 400 (a) to (d) described above may be made of an elastic material such as rubber, urethane foam, spring, etc. Also, the support parts 400 described above may be configured not to be flexible or elastically deformable.

[0118] The portable blower D2 may be positioned such that the open portion of the cover 300 faces the body when the strap ST is hung around the neck of the person. Alternatively, a belt may be passed through one or more belt loops B1 of the portable blower D2 so that the open portion of the cover 300 faces the body when the portable blower D2 is worn around the waist of the person. Alternatively, the arm may be passed through one or more armbands of the portable blower D2 so that the portable blower D1 is worn on the arm, and the arm may be moved so that the open portion of the cover 300 faces the body.

[0119] The portable fan D2 as described above has the following technical features and effects (1) to (7).

[0120] (1) Since the cover 300 is flexible and / or displaced by a predetermined amount toward the exhaust portion EX, even if the cover 300 hits a human body or an object, the portable fan D2 does not hit the human body or an object softly.

[0121] (2) When the cover 300 is bent and / or displaced a predetermined amount toward the exhaust section EX, the support section 400 is interposed between the exhaust section EX and the cover 300 to prevent the cover 300 from bending and / or displacing more than the predetermined amount toward the exhaust section EX, so that the exhaust section EX is not blocked by the cover 300 bending and / or displacing toward the exhaust section EX. Because the exhaust section EX is not blocked by the cover 300 in this way, it is also possible to use the portable blower D2 by placing the cover 300 facing the body while hanging it around the neck with the strap ST.

[0122] (3) When the support portion 400 extends from either the exhaust portion EX or the cover 300 to the other and is disposed at a distance from the other, the support portion 400 abuts against the other when the cover 300 is bent and / or displaced a predetermined amount toward the exhaust portion EX. With this simple configuration, the portable blower D2 can prevent the cover 300 from bending and / or displacing more than a predetermined amount toward the exhaust portion EX.

[0123] (4) When the support part 400 has the configuration (a) described above, the support part 400 has a pair of standing parts 410 and a connecting part 420. Therefore, when the cover 300 is bent and / or displaced a predetermined amount toward the exhaust part EX, the connecting part 420 of the support part 400 abuts against the exhaust part EX. At this time, the pair of standing parts 410 and the connecting part 420 are interposed between the exhaust part EX and the cover 300, making the support part 400 less likely to be crushed. Moreover, a ventilation space is defined by the support part 400 and the cover 300. Because the support part 400 is not present in the space outside (on both sides of) the pair of standing parts 410 in this ventilation space, the presence of the support part 400 makes it less likely that exhaust from the exhaust part EX and the ventilation space will be obstructed. When the support part 400 has the configuration (b) above, the support part 400 has a pair of standing parts 410, and therefore the pair of standing parts 410 of the support part 400 abuts against the exhaust part EX when the cover 300 is bent and / or displaced a predetermined amount toward the exhaust part EX. At this time, the pair of standing parts 410 support the cover 300, making the support part 400 less likely to be crushed. Moreover, a ventilation space is defined by the pair of standing parts 410 and the cover 300. Since the support part 400 is not present in the space outside (on both sides of) the pair of standing parts 410 in this ventilation space, the presence of the support part 400 makes it less likely that exhaust from the exhaust part EX and the ventilation space will be obstructed. When the support part 400 has the configuration (c) above, the support part 400 has a pair of upright parts 410 and a connecting part 420, and therefore the connecting part 420 of the support part 400 abuts against the cover 300 when the cover 300 is bent and / or displaced a predetermined amount toward the exhaust part EX. At this time, the pair of upright parts 410 and the connecting part 420 are interposed between the exhaust part EX and the cover 300, making the support part 400 less likely to be crushed. Furthermore, the space within the pair of upright parts 410 and the connecting part 420 can be used as a ventilation space, making it less likely that the presence of the support part 400 will obstruct exhaust from the exhaust part EX and the ventilation space. When the support part 400 has the configuration (d) above, the support part 400 has a pair of upright parts 410, and therefore the pair of upright parts 410 abut against the cover 300 when the cover 300 is bent and / or displaced a predetermined amount toward the exhaust part EX. At this time, the pair of standing portions 410 and the connecting portion 420 are interposed between the exhaust portion EX and the cover 300, so that the support portion 400 is less likely to be crushed.Moreover, since the space within the pair of standing portions 410 can be used as a ventilation space, the presence of the support portion 400 is less likely to interfere with the exhaust from the exhaust portion EX and the ventilation space.

[0124] (5) If the support portion 400 is flexible or elastically deformable in response to the flexing and / or displacement of the cover 300 toward the exhaust portion EX, the support portion 400 will flex or elastically deform while interposed between the cover 300 and the exhaust portion EX, making the portable blower D2 even softer in contact with the human body or objects.

[0125] (6) If the cover and / or support of the portable blower were molded from resin, costs for creating a mold to fabricate the cover and / or support would be necessary, resulting in high production costs for the portable blower. However, if the cover 300 of the portable blower D2 is made of the flexible fabric, flexible woven fabric, or a combination thereof, and the support 400 of the portable blower D2 is made of the flexible fabric, flexible woven fabric, or a combination thereof, costs for creating a mold would be unnecessary, thereby significantly reducing the production costs of the portable blower D2.

[0126] (7) Since the main body 100 is made of a flexible material, the portable blower D2 comes into contact with the human body or other objects more gently.

[0127] The portable blower described above is not limited to the above embodiment, and can be modified in any manner within the scope of the claims.

[0128] The main body 100 may be made of a rigid material such as resin, metal, or wood. Even in this case, the main body 100 can have any of the above-mentioned configurations except for the material. The main body 100 has an intake section IN and an exhaust section EX, and is provided with a fan 200. When the fan 200 is driven, air is introduced into the main body 100 from the intake section IN and exhausted from the exhaust section EX.

[0129] A plurality of the exhaust sections EX and / or intake sections IN may be provided. In this case, it is preferable to provide a plurality of covers 300 and support sections 400 according to the number of exhaust sections EX and / or intake sections IN. A configuration is possible in which some of the covers 300 cover one or more exhaust sections EX, and the remaining covers 300 cover one or more intake sections IN. In this case, a configuration is possible in which some of the support sections 400 are arranged between some of the covers 300 and one or more exhaust sections EX as described above, and the remaining support sections 400 are arranged between the remaining covers 300 and one or more intake sections IN as described above. Note that the support section 400 described above may be omitted.

[0130] Another aspect of the present invention provides a portable blower comprising: a main body having a sloped upper side; A portable blower including a fan provided in the main body, When the portable blower is carried by a person, the upper part of the main body faces upward and toward the person's body, The upper portion is provided with an exhaust port extending in the inclined direction of the upper portion, and the dimension of the exhaust port in a direction substantially perpendicular to the inclined direction gradually increases from above to below the exhaust port. This portable blower of another aspect of the present invention is not dependent on the portable blower of claim 1 of the present application. [Industrial Applicability]

[0131] The present invention can also be applied to air-conditioning clothing. In this case, the clothing has mounting holes 140, the fan 200 is fixed to the edge of the mounting holes 140, and the cover 300 is attached to the clothing to cover the intake or exhaust portion of the fan 200.
