The invention provides an anti-dry-burning control circuit. The anti-dry-burning control circuit comprises a resistance variable module and a first current source, the first current source is connected with the resistance variable module and the controlled heating module; the heating module is used for realizing a heating function; the resistance value variable module is used for detecting the resistance value change of the heating module in the heating process of the heating module, performing dry burning prevention protection when the resistance value of the heated heating module is larger than a set threshold value, and performing dry burning prevention protection when the resistance value of the heated heating module is smaller than or equal to the set threshold value. And the heating module is allowed to be heated. According to the embodiment of the invention, anti-dry-burning control can be realized. 本申请提供了一种防干烧控制电路，所述防干烧控制电路包括：阻值可变模块、第一电流源；所述第一电流源连接所述阻值可变模块和受控制的发热模块；所述发热模块，用于实现加热功能；所述阻值可变模块，用于在所述发热模块加热
