Technical Field
[0001] This utility model relates to the field of hair dryer technology, specifically a foldable hair dryer with negative ion hair care function. Background Technology
[0002] A negative ion hair dryer mainly consists of a negative ion generator and a semiconductor cooling device. When the hair dryer is working, it generates negatively charged ion particles (produced by the negative ion generator) and water vapor particles (produced by the semiconductor cooling device). These neutralize the positive charges often found in hair, thus smoothing frizz and making it more manageable and styling-friendly. This also eliminates static electricity, resulting in smoother, easier-to-comb hair and more ideal styling results.
[0003] As disclosed in the patent application CN214963188U, a hair dryer includes: a hair dryer body, an airflow channel assembly, and a negative ion generator. In this application, the airflow channel assembly is configured to have at least one air duct, and each air duct is connected to an independent air outlet. The negative ion generator is located at any position within the air duct and can be triggered and its operating status adjusted via a touch panel at the rear of the hair dryer body.
[0004] While it achieves the goal of generating a large number of negative ions through a negative ion generator to form an ion cluster, effectively neutralizing the positive charge on the hair and making it smoother and more flowing, this application, by attaching negative ions to the hair strands, can close the hair cuticles on the hair surface, thereby achieving moisture retention and hair repair.
[0005] However, this does not solve the problem that existing hair dryers are generally not convenient for drying the user's hair, are not easy to fold, and are not easy to adjust the air outlet position in multiple ways, which affects the range of air outlet position adjustment and the effect of hair care.
