A description will be given with reference to the drawings.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT In one embodiment shown in FIG. 1, a helmet 1
The headband 1a or the cap body 1b is engaged with a mounting portion 2 for mounting the headband 1a or the hat body 1b by means such as hooking or sandwiching, and one end thereof is mounted on the support frame 3. An electric cooling fan 6 composed of a blower propeller 4 and a motor 5 is attached to the support frame 3, and is arranged so as to be positioned on the back of the human head when wearing a helmet.

One end of each of the coated electric wires 7a and 7b is connected to the motor 5 so as to be able to conduct, and the other end is electrically connected to the switch 8. Via the switch 8, the coated electric wire 9a is connected to the battery 10 Connected to the positive pole of the
b is connected to the negative pole of the battery 10 and is configured so that the electric cooling fan 6 blows air when the switch 8 is turned on.

When a solar cell 28 is provided in addition to the battery 8, 7a, 7b or 9a, 9b can be similarly branched and connected to the solar cell 28 so as to be electrically connected to form a combined power source. I can. Further, instead of the battery 8, only the solar cell 28 can be used as a power source. The solar cell 28
The position of is placed on the head or the like where light is easily received.

The blower propeller 4 is made of resin, metal, wood, vinyl film or the like, and has a form in which the blowing ability is large in terms of fluid dynamics. It is preferable to use a propeller that discharges at least 1.5 liters / minute, preferably 50 liters / minute or more. Further, a net 21 for protecting the human body is provided around the propeller 8 for blowing air.

A jet nozzle 22 is arranged around the blower propeller 4, a water supply pipe 23 is connected to the jet nozzle 22, and the other end of the jet nozzle 22 is connected via a connection joint 24. , Is communicated with the pump 25.

The pump 25 injects the coolant in the coolant tank 25 via the water supply pipe 23 electrically, or manually, continuously, intermittently, or when the switch 8 is manually turned on. The nozzle 22 is configured to inject the coolant.

The cooling agent may be water, water containing a cooling agent, a gas such as compressed nitrogen, or dry ice, as long as it exhibits a cooling effect.

The battery 10 and the coolant tank 26 are fixed to the waist by a waist belt 27.

At least one electric cooling fan 6 is provided in the neck portion of the back of the head, which prevents heat stroke during extreme heat.
It is said that this happens because the blood sent to the head through the neck becomes too hot, and it is medically said that cooling the carotid artery and jugular vein in the neck of the occipital region has the greatest effect. In that case, the effect can be exerted by disposing the occipital region at the left and right centers of the neck. (The side view of one unit is omitted.)

Further, a desirable structure is that two left and right are mounted in total, as shown in FIGS. This is because it feels coolest when the backs of the left and right ears are cooled in terms of human sensation, and the inventor has found from a long-term sensory test that there is a position called this cool spot.

This is because the human ear and occipital region, and the part sandwiched between the back side of the neck and the human neck play a role of attaching the ears when the wind is received from the back, and the largest area to be cooled can be obtained.

As shown in FIGS. 1 and 2, the left and right ears are arranged one by one to cool the left and right rear ears and the neck, so that the maximum effect can be exhibited.

The embodiment shown in FIG. 3 shows another embodiment in which the covered electric wire is passed through the water supply pipe. With this structure, the covered electric wires 32a and 32b are included in the water supply pipe 31. This is because the functions of the head and the waist are connected by one tube, and the operability is greatly improved. FIG. 4 is a detailed partial cross-sectional view of the electric wire takeout portion A.

Sealing material 3 provided on a part of the water supply pipe 31
3, the covered electric wires 32a and 32b penetrate the inside, and the sealing material 33
Thus, the hermeticity is maintained.

The embodiment shown in FIGS. 5 and 6 shows a structure in which a battery and a coolant tank are provided on the head respectively.

The mounting portion 41 is engaged with the back band 1a or the cap body 1b, and one end thereof is joined to the support frame 42. The support frame 42 has the electric cooling fan 6 and the battery 4 attached thereto.
3 and the coolant tank 44 are fixed to the inside thereof, and with such a configuration, the cooling device is arranged only on the head, so that it is easier to use and can be downsized. The solar cell 45 may be used instead of the battery 43, or the solar cell 45 may be used in combination.

The embodiment shown in FIGS. 7 and 8 is different from the configuration shown in FIGS. 5 and 6 in that the injection nozzle 22 to the coolant tank 26 are used.
The most simplified embodiment without a water cooling system or the like constituted by the above will be shown.

The embodiment shown in FIG. 9 shows another structure of the mounting portion, in which the mounting portion 51 is hooked on the upper and rear portions of the ear,
One end of the structure is attached to the support frame 52 to support the head cooling device, and an upper band 53 can be attached to the other end of the attachment part 51 to increase stability, if necessary.

Since the structure of FIG. 9 is attached without engaging with the back band 1a or the cap body 1b, the cap shows a structure suitable for wearing a baseball cap having no strength or a cloth cap 54 for hiking. It is also possible to attach it regardless of the helmet.

It goes without saying that the structure of FIG. 9 can be applied to the first and second embodiments.

[0031]

As described above, an electric cooling fan and an injection nozzle are provided at the center of the neck of the occipital region or at the rear of the left and right ears, which can be said to be the cool spot, which is most effective for preventing heat stroke. By providing the most suitable cooling effect to the human body by arranging it, it is possible to significantly reduce heat stroke, which has been a long-standing problem in summer disasters, and to achieve extinction.
