BACKGROUND

The electric splint is a hairdressing tool. The hair is heated and softened by the electric splint, and the hair is shaped after cooling. The traditional electric splint has the following problems during use: as the hair heated by the electric splint cools slowly, the hair straightening operation takes a longer time, and the hair is prone to be deformed during the cooling process; in addition, when straightening hair, the hair clamped by the electric splint not only needs to be held by hand, but the hair will be overlapped instead of uniformly distributed, which affects the clamping operation and the straightening effect.

Air outlet holes are arranged on both sides of the electric splint to realize the rapid cooling and shaping of the hair. However, the air outlet holes are arranged perpendicular to the upper and lower splints, so that the cold air blown from the air outlet holes is very close to the splints. On the one hand, the surface temperature of the heated hair is relatively high, and the cooling effect is not ideal when the temperature is temporarily cooled by the cold air from the air outlet holes, on the other hand, part of the cold air is directly blown to the splint, thereby affecting the heating effect of the splint.
