As preferably, be provided with insulating trip between described high-temp PTC heat generating core and the low temperature PTC heat generating core, be wrapped with the yellow ply of paper of insulation at high-temp PTC heat generating core and low temperature PTC heat generating core.

As preferably, separate with mica paper between the top of described PTC heat generating core and the metal heat sink die cavity.

The utlity model has convenient, high, the energy savings, safe of thermal conversion efficiency of temperature transition, low cost and other advantages, have specifically following some:

1. many grades of automatic constant-temperatures adopt two PTC heat generating cores of different temperatures and power, and the combination by between two PTC heat generating cores of change-over switch control can provide basic, normal, high third gear temperature and power.

2. reduce the circuit design space,, in circuit design, do not need temperature-control circuit, thereby save a lot of design spaces, reduced production cost based on the automatic constant-temperature characteristic of PTC, safe in utilization;

3. it is little to consume energy, and PTC promptly enters keeping warm mode automatically after reaching maximum temperature, and this moment, PTC was in high-impedance state, made that the electric current in the circuit is very little, and consumed power is little;

4. thermal conversion efficiency height, programming rate is fast, rise to fast after the start use to scope (180-200 ℃), and not rubescent under "on" position, can all convert electric energy to heat energy, the electric conversion efficiency height.

5. the speed of rising again is fast, can rise again rapidly after the clamping plate pull head is sent out.And can not burn hair because of temperature overshot exceeds set definite value, and having improved the quality that pull head is sent out, thereby made hair brighter, more flexible and bring soft and smoothly and healthy to hair, straight hair is effective.
