[0015] Embodiments of the present invention will be described below with reference to the drawings, but the present invention is not limited to these embodiments.

[0016] [Embodiment 1] <Invention blower 1> FIG. 1 and FIG. 2 show the blower 1 of the present invention according to Embodiment 1. The blower 1 of the present invention includes a "motor (2)", an "impeller (3)" connected to the rotating shaft 21 of the motor 2, an "outer shell (4)" surrounding the motor 2 and the impeller 3, and a "connector box (5)" provided on the outer shell 4. Further, a "holding hook (6)" is provided on the outer shell 4.

[0017] - Motor 2 - The motor 2 means a mechanical element that outputs a rotational motion by using the force generated by the Lorentz force (interaction between magnetic field and current). In the present embodiment, as the motor 2, a mechanism (commercially available model electric motor) that rotates the rotating shaft 21 by the supplied electric power is used.

[0018] - Impeller 3 - The impeller 3 includes a boss 31 and a plurality of blades 32 provided around the boss 31. The boss 31 is a member that forms the center of rotation of the impeller 3, and the blades 32 rotate with the rotation of the boss 31 and play a role in generating a flow of air in a certain direction. In the present embodiment, as the impeller 3, a seven - blade rotor having seven umbrella - shaped blades 32 arranged radially around the boss 31 is used. The connection between the impeller 3 and the motor 2 is made by exposing the rotating shaft 21 of the motor 2 from the end face of the boss 31 through a through - hole 33 provided in the central portion of the boss 31 of the impeller 3 and screwing a screw (N) onto the rotating shaft 21.

[0019] - Outer shell 4 - The outer shell 4 ensures safety during use of the blower 1 of the present invention by surrounding the motor 2 and the impeller 3. Furthermore, since the outer shell 4 needs to have a structure that allows the airflow generated by the rotation of the impeller 3 to pass through, it is equipped with an intake port 41 and an exhaust port 42 having multiple openings. In this embodiment, the outer shell 4 consists of two parts: a dome-shaped outer shell body 4A and a lid 4B that covers the opening of the outer shell body 4A. The female screw portion provided on the inner surface of the outer shell body 4A and the male screw portion provided on the lid 4B are screwed together to form a space surrounding the motor 2 and the impeller 3. The opening of the outer shell body 4A and the periphery of the intake port 41 of the lid 4B are provided with flanges (FA, FB) that protrude outward, and when the outer shell body 4A and the lid 4B are screwed together, the flanges (FA, FB) face each other.

[0020] - Connector Box 5 - As shown in Figure 3, the blower 1 of the present invention is designed to drive the motor 2 by power supplied from a battery (B) via a cable (C), and the connector box 5 is equipped with a connector 51 for connecting the terminal (C1) of the cable (C). The connector 51 and the motor 2 are connected via wiring (not shown), and by connecting the terminal (C1) of the cable (C) connected to the battery (B) to the connector 51, electricity can be supplied to the motor 2. In this embodiment, the connector box 5 is provided on the exhaust port 42 side (outer shell body 4A) of the outer shell 4.

[0021] -Retaining hook 6- The retaining hook 6 is responsible for holding the cable (C) connected to the connector box 5. In this invention, the retaining hook 6 is provided at multiple locations on the outer shell 4. In this embodiment, the retaining hook 6 is made of a bent piece with an L-shaped cross-section and is provided at two symmetrical positions on either side of the connector box 5. Since the connector box 5 is located on the exhaust port 42 side (outer shell body 4A) of the outer shell 4, the retaining hook 6 is also located on the exhaust port 42 side (outer shell body 4A) of the outer shell 4. Furthermore, in this embodiment, the top of the retaining hook 6 is at the same height as the apex of the outer shell 4 on the exhaust port 42 side (the apex of the outer shell body 4A) (see Figure 3(b)).

[0022] <Inventive clothing 10> As shown in Figure 4, the blower 1 of the present invention having the above configuration is attached to the garment body (W) to form the garment 10 of the present invention. The garment 10 of the present invention cools the inside of the garment body (W) by blowing outside air into the garment body (W) using the blower 1 of the present invention. In this embodiment, holes (H) are made in multiple locations (two locations) of the garment body (W), and the blower 1 of the present invention is attached to each hole (H).

[0023] As shown in Figure 5, in the blower 1 of this embodiment, the male threaded portion of the lid 4B is inserted into a hole (H) provided at an appropriate location on the garment body (W), and screwed into the female threaded portion of the outer shell body 4A inside the garment body (W). The flange (FA) of the outer shell body 4A and the flange (FB) of the lid 4B sandwich the periphery of the hole (H), thereby attaching it to the garment body (W). Subsequently, the terminal (C1) of the cable (C) connected to the battery (B) is connected to the connector 51 of the connector box 5. The connected cable (C) is then held in place by hooking it onto a retaining hook 6 provided on the outer shell 4 of the blower 1 of this embodiment. Furthermore, the battery (B) is stored in a pocket (P) provided on the back of the garment body (W) (see Figure 4).

[0024] By the way, in the blower 1 of the present invention, which is attached to the garment body (W) by performing the attachment work, the connector box 5 will be located on the periphery of the hole (H), but it is unknown exactly where on the periphery of the hole (H) it will be located.

[0025] Therefore, depending on the position of the connector box 5 when the blower 100 is attached to the hole (H) in the garment body (W), excessive bending or other stress may be applied to the cable (C).

[0026] In this regard, the blower 1 of the present invention has multiple retaining hooks 6 for holding the cable (C) on the outer shell 4. As shown in Figure 6, it is possible to select the retaining hook 6 that does not put a load on the cable (C) and hold the cable (C) there.

[0027] Thus, according to the present invention, the storage capacity of the cable (C) can be improved without placing an excessive load on the cable (C).

[0028] In this embodiment, the retaining hook 6 uses an L-shaped bent piece and is provided at two symmetrical positions on either side of the connector box 5. However, the shape and mounting location of the retaining hook 6 are not particularly limited.

[0029] However, if the retaining hooks 6 are provided at two locations on either side of the connector box 5, at least one of the retaining hooks 6 can be positioned in a holding position where no load is placed on the cable (C).

[0030] Furthermore, in this embodiment, the connector box 5 and retaining hook 6 are provided on the exhaust port 42 side (outer shell body 4A side) of the outer shell 4, but the connector box 5 and retaining hook 6 may also be provided on the intake port 41 side (lid 4B side) of the outer shell 4. However, if the connector box 5 and retaining hook 6 are provided on the intake port 41 side (lid 4B side) of the outer shell 4, the battery (B) and cable (C) will be located outside the garment body (W), so it is preferable to provide the connector box 5 and retaining hook 6 on the exhaust port 42 side of the outer shell 4.

[0031] Furthermore, in this embodiment, the top of the retaining hook 6 is positioned at the same height as the vertex on the exhaust port side of the outer shell 4 (the vertex of the outer shell body 4A). However, the positional relationship between the top of the retaining hook 6 and the vertex on the exhaust port 42 side of the outer shell 4 is not particularly limited. However, if the top of the retaining hook 6 is positioned at the same height as the vertex on the exhaust port side of the outer shell 4 (the vertex of the outer shell body 4A), the tops of the retaining hooks 6, which are placed in multiple locations, will be flush with the vertex on the exhaust port side of the outer shell 4, eliminating any protruding parts and improving the usability of the garment 10 of the present invention.

[0032] Furthermore, the present invention can be implemented in various other forms without departing from its spirit or main features. Therefore, the embodiments described above are merely illustrative in all respects and should not be interpreted restrictively. The scope of the present invention is defined by the claims and is not restricted in any way by the text of the specification. Moreover, any modifications or changes falling within the equivalent scope of the claims are all within the scope of the present invention. [Industrial applicability]
