technical field

The utility model relates to the field of hair dryers, in particular to a graphene hair dryer.

Background technique

At present, the traditional hair dryer uses the heating wire installed on the mica bracket in the casing to generate heat, and the fan blade is driven to rotate by the motor installed in the casing. When the fan blade rotates, the air is sucked in from the air inlet, and the centrifugal airflow thus formed is blown out from the front nozzle of the fan duct.

During the heating process of the heating wire, the insulating mica sheet is also heated. After heating, the mica sheet produces and evaporates mica particles, which will block the pores of the scalp and cause hair loss. Long-term use has a certain impact on the human body, so graphene coating is used to solve this problem.

The graphene far-infrared electric heating film is made of graphene, indium oxide, tin oxide, titanium oxide and other mixed liquids or mixed powders sintered on the substrate.
