[0025] The working principle of this utility model:

[0026] During use, when the user needs to dissipate heat for the head, the cooling fan 5 needs to be turned on. When the cooling fan 5 is turned on, the semiconductor heat sink 6 also needs to be turned on. Wind is blown into the inner cavity of the hat 1 through the cooling fan 5, and the air duct will blow the low-temperature gas generated by the semiconductor heat sink 6 into the hat 1, thereby dissipating heat for the user's head. Since there is a gap between the head pad 3 and the hat 1, the air duct will fully dissipate heat to the back and front sides of the head. After long-term use, a large amount of dust is easily accumulated on the surface of the dustproof net 708, which affects the effect of air intake. The motor 701 needs to be turned on, and the gear 702 is driven to rotate by the rotation of the motor 701. When the gear 702 rotates, the tooth plate frame 703 is driven to move. The movement of the tooth plate frame 703 drives the brush 707 to move, thereby cleaning the dust on the dustproof net 708.
