PROBLEM TO BE SOLVED: To provide an automatic shut-down device of a simple structure for a heating equipment, simple and easy to manufacture and operate, and capable of being put into a practical use, further capable of regulating the level of CO and CO2 contained in the air in a heating part. SOLUTION: The automatic shut-down device is provided with a core cylinder 2 capable of being moved up/down by a rotation shaft 1, a ratchet 4 regulating the rotation of the shaft 1, a lever 6 attached pivotally to a frame 5 to continuously control the ratchet 4, a shutoff knob 7 and a safety weight 8 which respectively operate to release the ratchet 4 from the lever 6, and shut off the combustion. Further a shut-off plate 20 for actuating the shutoff of the lever 6, a coil spring 30 for operating the plate 20, while returning to the former shape to shut off the combustion, a biasing spring 40 which normally serves a bias and increases the action force of the coil spring 30 in its spring-back. |
