The utility model relates to a fire-proof and high thermal efficiency stageless temp-controlled safety high-grade electric blanket, comprising a power supply line, a one-way controlled silicon arranged in a controller, a resistance-capacity device R2 and a capacitor C3 which is fixed in the housing of the controller. A bandlet wire spiral electric heating conducting wire is inserted with the controller, and a disposable triggered switching circuit formed by elements of the resistive-capacity device of the one-way controlled silicon realizes the protective state of a heating wire, which can not be realized by a switch of an ordinary electric blanket. The utility model not only can get heating, but also can automatically cut off a power supply due to fault to realize protection; the utility model has the advantages of improved thermal efficiency of the electric heating wire and energy saving, being an ideal electric blanket which can get heating with ensured safety.
