Hair styling device

Abstract

The present disclosure relates to hair styling equipment technologies, in particular to a hair styling device, which includes two clamping plates and a handle connected with the two clamping plates. Each clamping plate includes a shell, a heating plate, and at least one connecting structure connected between the shell and the heating plate. A heat insulation gap is defined between the shell and the heating plate. The heat insulation gap is capable of being reduced along with movement of the heating plates relative to the shells. The hair styling device uses air as the insulation material due to the heat insulation gap, which greatly reduces the heat transmitted from the heating plate to the shell. The height of the insulation gap can be reduced along with movement of the heating plate, which can better clamp the hair and provide users with a better hair styling experience.
