At this time, since the cooling surface of the thermoelectric semiconductor 180 faces the direction of the first air flow path 150, the air flowing through the first air flow path 150 comes into contact with the thermoelectric semiconductor 180.

The cooling surface of the thermoelectric semiconductor 180 absorbs heat from the air flowing through the first air passage 150 to lower the temperature of the air inside the first air passage 150.

The air having lowered temperature in contact with the cooling surface of the thermoelectric semiconductor 180 is supplied into the body 110 through the plurality of air passages 190. The low temperature air causes the heat generated by the user's head to cool down, causing the temperature to drop.

The air having a temperature which is raised in contact with the user's head is caused to flow along the second air passage 170 by the exhaust fan 120. When the air inside the body 110 is exhausted by the exhaust fan 130 along the second air passage 170, it comes into contact with the heat generating surface of the thermoelectric semiconductor 180.

At this time, the heating surface of the thermoelectric semiconductor 180 is cooled by the air flowing through the second air flow path, and the heated air is discharged to the outside by the exhaust fan 130.

As described above, the external air can be sucked into the body 110, and the cool air can be supplied to the thermoelectric semiconductor 180 through the cooling surface.

In addition, it is possible to prevent the shape of moisture on the face shield by discharging the user's exhalation through the second air passage 160, and also to maintain the air inside the body 110 comfortably .
