[0009] (Embodiment 1) As shown in Figures 1 to 6, the cooling garment blower fan of this embodiment includes a cylindrical air tunnel 2 having a flange 1 for attaching to garments that protrudes outward and extends in the outer circumferential direction on its outer periphery, a fan 3 arranged within the air tunnel 2, a motor 4 for driving the fan 3, a front guard 5 detachably arranged on the air intake side of the air tunnel 2, and a rear guard 6 detachably arranged on the air outlet side of the air tunnel 2.

[0010] As shown in Figs. 4 to 6, the air tunnel 2 is cylindrical, and a breathable, disc-shaped front guard 5 is provided on the air intake side. The front guard 5 has a mesh shape, and on the outer periphery facing the wind tunnel 2, as shown in Figs. 4 and 5, four protruding engagement portions 5a are arranged at 90 degree intervals. The locking portion 5 a is shaped to protrude inward from the outer periphery of the front guard 5 in the inward direction.

[0011] Correspondingly, four locking portions 2a are provided on the outer periphery of the wind tunnel 2. As shown in Figs. 4 and 5, the locking portion 2a has an opening 2b formed by cutting out the outer periphery of the flange 1, and a protrusion 2c disposed at a predetermined position from this opening 2b. Therefore, when attaching the front guard 5 to the air intake side of the wind tunnel 2, first the front guard 5 is abutted against the air intake side of the wind tunnel 2 with the locking portion 5a of the front guard 5 aligned with the opening 2b of the locking portion 2a, and then the front guard 5 is rotated towards the protrusion 2c of the locking portion 2a, so that the locking portion 5a of the front guard 5 slips under the protrusion 2c of the locking portion 2a of the wind tunnel 2 (on the rear guard 6 side), and as a result, the breathable, disc-shaped front guard 5 is attached to the air intake side of the wind tunnel 2.

[0012] When removing the front guard 5 from the air intake side of the air tunnel 2, the front guard 5 is rotated to the side opposite the protrusion 2c of the engaging portion 2a of the air tunnel 2, that is, to the opening 2b side of the engaging portion 2a. Then, the locking portion 5a of the front guard 5 can be moved from the opening 2b of the locking portion 2a of the wind tunnel 2 to the side opposite the rear guard 6, thereby allowing the front guard 5 to be removed from the air intake side of the wind tunnel 2. That is, in this embodiment, the front guard 5 is configured to be detachable from the air intake port side of the wind tunnel 2 .

[0013] The wind tunnel 2 is provided with a claw-shaped first locking portion 2e and an opening-shaped first engagement portion 2f. The first locking portion 2e and the first engagement portion 2f are arranged on opposing portions of the outer periphery of the wind tunnel 2 or in the vicinity thereof. In other words, the first locking portion 2e and the first engagement portion 2f are arranged on opposite sides of the center of the wind tunnel 2. The first locking portion 2e and the first engagement portion 2f are arranged in line with an imaginary straight line perpendicular to the central axis of the wind tunnel 2, or are arranged slightly offset from the imaginary line.

[0014] As shown in FIG. 6, the motor 4 is provided in a cylindrical motor case 7 provided in the wind tunnel 2. A circular power supply case 8 is integrated with the rear guard 6 side of the motor case 7 as a power supply section of the motor case 7 . A plurality of beams 2d are provided on the outer periphery of the power supply case 8 for fixing the power supply case 8 to the axial center part of the air outlet side of the wind tunnel 2. In other words, the power supply case 8 is fixed to the axial portion on the air outlet side of the wind tunnel 2 by the beam 2d, and by integrating the power supply case 8 and the motor case 7, the motor case 7 is fixed to the axial portion within the wind tunnel 2, and the motor 4 is also fixed to the axial portion within the wind tunnel 2. The fan 3 is attached to the rotating shaft of the motor 4.

[0015] The power supply case 8 is a power supply section for the motor 4. One end of a power supply line 9 to the motor 4 is arranged inside the power supply case 8. The other end of the power supply line 9 extends along the beam 2d to the outer periphery of the wind tunnel 2 as shown in FIG. 9 and is connected to a power supply terminal 10 provided on the outer periphery of the wind tunnel 2. As shown in FIG. 8, the power supply terminal 10 is provided with a power outlet 11 to which a power plug 12 from a battery (not shown) is detachably attached.

[0016] Next, the rear guard 6 will be described. As shown in Figs. 4 to 9, the rear guard 6 has air permeability and is bowl-shaped with an opening on the wind tunnel 2 side. The rear guard 6 is detachably attached to the air outlet side of the wind tunnel 2. First, as shown in FIG. 3, a flange 6a is provided on the outer periphery of the rear guard 6, which protrudes outward and extends in the outer periphery direction so as to sandwich the clothing 13 between the flange 1 of the air tunnel 2. As is well known, a circular opening is provided in the clothing 13, and the rear guard 6 side of the wind tunnel 2 is inserted from the front side of the clothing 13, and then the rear guard 6 is attached to the wind tunnel 2 on the back side of the clothing 13, so that the clothing 13 is attached to the clothing 13 by sandwiching the flange 6a between the clothing 13 and the brim 1 of the wind tunnel 2, as shown in Figure 3.

[0017] A specific structure will now be described. The rear guard 6 is provided with an opening-shaped second locking portion 6b that is engaged with a claw-shaped first locking portion 2e provided in the wind tunnel 2 as shown in FIG. 5, and a claw-shaped second engagement portion 6c that is engaged with an opening-shaped first engagement portion 2f provided in the wind tunnel 2 as shown in FIG. 9. The second locking portion 6b and the second engagement portion 6c are disposed on opposing portions of the outer periphery of the rear guard 6 or in the vicinity thereof. That is, the second locking portion 6b and the second engagement portion 6c are disposed on opposite sides of the center of the rear guard 6. The second locking portion 6b and the second engagement portion 6c are disposed in line with an imaginary straight line perpendicular to the central axis of the rear guard 6, or are disposed slightly offset from the imaginary line. The claw-shaped second engagement portion 6c is provided on the free end side of the lever 6d and is constantly biased toward the first engagement portion 2f of the air tunnel 2.

[0018] With the second engagement portion 6b of the rear guard 6 engaged with the first engagement portion 2e, the rear guard 6 is attached to the wind tunnel 2 by engaging the second engagement portion 6c of the rear guard 6 with the first engagement portion 2f. On the other hand, when disengaging the claw-shaped second engagement portion 6c from the first engagement portion 2f of the wind tunnel 2, by operating the free end of the lever 6d toward the outside of the rear guard 6 in Figure 4, the claw-shaped second engagement portion 6c can be disengaged from the first engagement portion 2f of the wind tunnel 2, thereby moving the rear guard 6 in the opening direction away from the wind tunnel 2. The first engagement portion 2f and the first locking portion 2e of the wind tunnel 2 may be provided on the front guard 5 in a state where the wind tunnel 2 is attached. Also, the first engagement portion 2f may be provided on the wind tunnel 2 and the first locking portion 2e may be provided on the front guard 5, or the first engagement portion 2f may be provided on the front guard 5 and the first locking portion 2e may be provided on the wind tunnel 2.

[0019] In the bowl-shaped rear guard 6, a circular opening 6e is formed in a portion corresponding to the circular power supply case 8. The diameter of the circular opening 6e of the rear guard 6 is smaller than the diameter of the power supply case 8, and a retaining portion 6f is provided on the outer periphery of the opening 6e of the rear guard 6, which covers the outer periphery of the end of the power supply case 8 on the rear guard 6 side. As a result, the rear guard 6 is detachably attached to the air outlet side of the air tunnel 2.

[0020] In addition, in a state where the rear guard 6 is attached to the air outlet side of the air tunnel 2 in this manner, the power plug 12 is inserted into the power outlet 11 through an opening 6g provided in the rear guard 6 as shown in FIG. 7. More specifically, a terminal cover 6h is formed on the outer surface of the rear guard 6 to be attached to the power supply terminal 10 of the air tunnel 2, and an opening 6g is formed in this terminal cover 6h. The terminal cover 6h is adjacent to the lever 6d in the circumferential direction on the rear guard 6 and protrudes outward. The opening 6g is formed on the side surface of the terminal cover 6h. When the terminal cover 6h is attached to the power supply terminal 10, the opening 6g is aligned approximately coaxially with the power outlet 11, and the power plug 12 is connected to the power outlet 11 through the opening 6g. Therefore, when removing the rear guard 6 from the wind tunnel 2, it is necessary to first unplug the power plug 12 from the power outlet 11. In other words, when the rear guard 6 is removed from the wind tunnel 2 and the fan 3 is exposed, the motor 4 is not energized and the fan 3 does not rotate, making it safe. When removing the rear guard 6 from the wind tunnel 2 in this manner, in the state shown in Figure 7, for example, insert the thumb of one hand into the opening 6e of the rear guard 6 and place the thumb on the power supply case 8 while holding the rear guard 6, wind tunnel 2, and front guard 5 with that one hand and operate the free end of the lever 6d of the rear guard 6 with the thumb of the other hand toward the outside of the rear guard 6 in Figure 4, thereby disengaging the claw-shaped second engagement portion 6c from the first engagement portion 2f of the wind tunnel 2, and thereby allowing the rear guard 6 to be easily moved in the opening direction from the wind tunnel 2.

[0021] In addition, when washing the removed rear guard 6 with water, if the rear guard 6 is held with, for example, the thumb of one hand inserted into the opening 6e of the rear guard 6, the rear guard 6 will not drop when washing with water, and washing with water can be easily performed.

[0022] As described above, in this embodiment, the front guard 5 and the rear guard 6 can be removed from the air tunnel 2 which houses the fan 3 and the motor 4, so that both the front guard 5 and the rear guard 6 of the fan 3 are exposed to the outside of the air tunnel 2, making it easy to clean both sides of the fan 3. Moreover, both the front guard 5 and the rear guard 6 can be washed with water, which provides high convenience. Furthermore, when the rear guard 6 is removed from the air tunnel 2, the cooling garment blower fan can be removed from the clothes 13, and at that time, the surface of the fan 3 on the rear guard 6 side is always exposed, so that the surface of the fan 3 on the rear guard 6 side, which is easily soiled, and the rear guard 6 can be frequently cleaned. The reason why the rear guard 6 is dirty is believed to be that the wind becomes turbulent after passing through the fan 3.

[0023] In the above embodiment, the brim 1 on the outer periphery of the cylindrical air tunnel 2 is horizontal, so the air tunnel 2, the front guard 5, and the rear guard 6 are arranged parallel to the clothing 13 as shown in Figure 3. However, if the brim 1 on the outer periphery of the air tunnel 2 is tilted as shown in Figure 11, the air tunnel 2, the front guard 5, and the rear guard 6 will be arranged at an angle to the clothing 13 as shown in Figure 10.

[0024] Although the embodiment of the present invention has been described in detail above, the present invention is not limited to the above embodiment, and various design modifications can be made to the present invention without departing from the scope of the claims. [Explanation of symbols]
