The helmet with built-in fan is equipped with a small fan at the back of the helmet, and this small fan does not blow strong wind to achieve the purpose of cooling down like the fan in our daily household, but discharges the air inside the helmet and then inputs cold air to achieve the purpose of effectively cooling down.
