The utility model relates to an intelligent temperature-controlling iron socket with the advantages of controllable temperature, small volume, low maintenance cost, long servicing life and low energy consumption, wherein, a socket body, a CPU chip, a tier number controlling circuit and a trigger circuit are connected with a transformation circuit, a rectification filter circuit and a constant voltage control circuit in order between the power and CPU to provide the constant working voltage and direct current to the CPU. The CPU is connected with power and receives the signal from the tier number controlling circuit then sends out a signal to the trigger circuit to fuse and burn the electrical iron body; and a tier number displaying circuit on the electrical iron is used for showing a real-time tier numbers on the CPU; and a fusing and burning display circuit on the CPU is used for showing the working state of the electrical iron. The utility model adopts different modern technical means to achieve the constant temperature of the electrical iron and the constant temperature control can be achieved only by using ordinary electrical iron on the socket body.
