Abstract
An over-temperature protection structure and a hair drying apparatus is provided. The over-temperature protection structure includes a main body, a heater and an over-temperature protector; the heater includes an inner layer and a heating element, the inner layer being arranged on an inner side of the heating element and configured to support the heating element. Therefore, when the temperature of the heater is relatively high, the heater and the power source will be disconnected and the heater will cease to work, avoiding damaging the heater and surrounding elements because of overheat, thereby protecting the whole hair drying apparatus.
