Hair curler with high heating efficiency and convenience in use

Abstract

The present invention relates to a hair curler with high heating efficiency and convenience in use, including a handle. One end of the handle is connected to a heating portion, and a starting switch connected to a control panel is arranged on the handle. The heating portion includes a bracket connected to the handle and a heat generating layer arranged outside the bracket. An outer surface of the heat generating layer is connected to an outer heat-conducting layer. After generating heat, the heat generating layer transfers the heat to the outer heat-conducting layer, causing the outer heat-conducting layer to heat up and act on hair. An inner heat-conducting layer or an inner heat-insulating layer is arranged between the heat generating layer and the bracket. The heat-conducting layer made of a titanium metal acts on the hair; therefore, the hair curling process becomes more healthily, and the heat-conducting efficiency is higher.

What is claimed is: 
     
         1 . A hair curler with high heating efficiency and convenience in use, comprising a handle, wherein one end of the handle is connected to a heating portion, a control panel is arranged within the handle, a starting switch connected to the control panel is arranged on the handle, the heating portion comprises a bracket connected to the handle and a heat generating layer arranged on an outer surface of the bracket, the outer surface of the heat generating layer is connected to an outer heat conducting layer, and after generating heat, the heat generating layer transfers the heat to the outer heat-conducting layer, causing the outer heat-conducting layer to heat up and then act on hair. 
     
     
         2 . The hair curler according to  claim 1 , wherein an inner heat-conducting layer or an inner heat-insulating layer is arranged between the heat generating layer and the bracket. 
     
     
         3 . The hair curler according to  claim 2 , wherein the outer heat-conducting layer, the heat generating layer and the inner heat-conduction layer or the inner heat-insulating layer are all provided with a notch, the bracket is provided with an L-shaped groove which longitudinally extends into the bracket, both the L-shaped groove and the notch are provided with an L-shaped locking block, and the L-shaped locking block is only capable of axially moving along the heating portion on the L-shaped groove and the notch. 
     
     
         4 . The hair curler according to  claim 3 , wherein the outer heat-conducting layer is provided with an L-shaped tab which longitudinally extends to the bracket, and the L-shaped groove is internally provided with a tab surface corresponding to the L-shaped tab to enable the outer heat-conducting layer to axially move along the bracket. 
     
     
         5 . The hair curler according to  claim 2 , wherein the outer heat-conducting layer and the inner heat-conducting layer are made of titanium metal for heat conduction, and the heat generating layer is a heat generating film. 
     
     
         6 . The hair curler according to  claim 1 , wherein a pressing portion is arranged on the handle, and a clamping force for the hair is formed between the pressing portion and the heating portion. 
     
     
         7 . The hair curler according to  claim 6 , wherein the pressing portion comprises a pressing spring connected to the handle, and an aluminum clip arranged on a surface of the heating portion and connected to the pressing spring, the pressing portion further comprises a pressing handle connected to the aluminum clip, when the pressing handle is subjected to force, the pressing spring is compressed and drives the aluminum clip to move away from the heating portion, and when the pressing force on the pressing handle is released, the spring after compression returns to an original shape thereof and drives the aluminum clip to move towards the heating portion. 
     
     
         8 . The hair curler according to  claim 1 , wherein one end of the heating portion is connected to the handle, and the other end is connected to a rocket-shaped nozzle, so that an independent space is formed inside the hair curler, and the other end of the handle is connected to a connecting wire for conducting electricity to the control panel. 
     
     
         9 . The hair curler according to  claim 8 , wherein the connecting wire comprises a male end connected to the control panel and a female end connected to commercial power, and the male end is inserted into the female end to electrify the control panel. 
     
     
         10 . The hair curler according to  claim 8 , wherein a silicone ring is arranged at a connection between the handle and the heating portion, a pressure relief hole is formed in the handle, a pressure relief valve that is inserted into the pressure relief hole is arranged on the silicone ring, an end portion of the pressure relief valve is provided with a gas blocking plug, when the pressure relief valve is pressed, the gas blocking plug moves to open the pressure relief hole, and when the pressing force on the pressure relief valve is released, the gas blocking plug moves to the pressure relief hole for sealing.
