Description

Technical Field

[0001] The utility model relates to the technical field of hair dryers, in particular to a multifunctional temperature control system for hair dryers. Background Art

[0002] Nowadays, many girls may have long hair, but they are in a hurry to go out after washing. Often, the hair cannot be dried in a short time or the hair is burnt by high temperature, and the scalp is burned, which is very annoying. However, some hair dryers now can only make some simple adjustments to the temperature and cannot be fully adjusted to the appropriate temperature. Sometimes the hot air temperature is too high and may damage the hair.
