NOVELTY - The utility model relates to the technical field of heater, especially relates to an automatic power-off graphene heater, comprising an explosion-proof shell and a heating tank; the heating tank is installed in the explosion-proof shell; the left and right sides of the upper and lower ends of the inner wall of the explosion-proof shell and the left and right sides respectively the upper and lower ends of the heating tank are fixedly connected with with two fixing blocks distributed left and right; a guide rod is fixedly connected with between the left and right adjacent fixing blocks; a telescopic frame is installed between the upper and lower adjacent two guide rods; the upper and lower two ends of the telescopic frame are rotatably connected with two guide blocks; the guide block is sleeved and slid on the periphery of the guide rod; by the flexibility of the telescopic frame, combining the buffer performance of the buffer spring, improving the stability of the heating tank when working; when the inner pressure of the heating tank is too high to be broken, by the buffer performance of the buffer spring so as to reduce the impact force generated when the heating tank is exploded; then through the explosion-proof shell for separating and protecting the explosion of the heating tank, which is good for reducing safety hidden trouble.
