In actual use, the heating plate is used to heat the hair, and the heat loss is fast and large. When the heat is unloaded, the temperature difference between the heating element and the heating plate is not obvious. After the heating load, the surface temperature of the heating plate loses quickly, and the temperature difference between the heating element and the heating plate is large. At this time, it is obviously inappropriate to display the temperature of the heating plate with the temperature of the heating element. In the prior art, the heating power is controlled solely according to the temperature of the heating element, which easily leads to the situation that the temperature of the heating element meets the requirement but the temperature of the heating plate is low, thereby affecting the hair styling effect; or if the heating temperature is judged solely by the temperature of the heating plate, it is easy for the heating plate to be in a cooling or heating state and cannot be controlled in time.

[0076] It should be noted that the temperature difference detected by the first temperature detector 3 and the second temperature detector 4 at the same time mentioned in the present application document is the difference between the temperature detected by the first temperature detector 3 and the temperature detected by the second temperature detector 4 at the same time. Generally, the temperature detected by the first temperature detector 3 is greater than or equal to the temperature detected by the second temperature detector 4 at the same time.
