ABSTRACT:
An automatic shut-off device for a gas stove, and more particularly, a safety valve control device that can be retrofitted between the gas inlet pipe and the catch base of the stove. The device includes a coupling such that operation of the knob of the gas stove at the time operates the circuit of a gas safety valve control device. This operation causes the forward movement of a function shaft of the gas safety valve device and opens the gas intake valve to supply the gas to the stove burner. The function shaft is also subject to the control by an electromagnetic control rod to maintain the open state of the gas intake valve. In case the fire goes out accidently, the circuit device energizes an electromagnetic coil to attract upwardly an electromagnetic control rod, thereby disconnecting the function shaft, which is spring loaded, and which in turn operates the gas intake valve. This action thus disconnects the gas supply to the stove. Also, if the cooking time is too long, and the fire does not go out (e.g., one forgets to turn off the gas) or the gas at the stove burner can not be ignited within the given time, the device will also shut off automatically the gas intake valve.
