Ordinary heating rod:
1/ Constant temperature: after 15 minutes the temperature will be maintained at about 35 degrees.
2/ No automatic power-off: Need to be disconnected after about 30 minutes.
There is a risk of low temperature burning and melting after heating too long.

2/ Automatic power-off:
In about 30 minutes, the heating rod reaches 70 degrees Celsius and automatically powers off
(the surface temperature of the doll is less than 40 degrees Celsius).
3/ Automatic heating: the temperature will gradually cool down after reaching the maximum value and resume heating after reaching room temperature. The repeated cyclic process should not exceed 2 hours.
