Abstract

PURPOSE:To improve a safety characteristic of a catalyst heater used for a gas smoking and insect killer etc. by a method wherein a shape memory alloy is fixed to the other end of a safe gas lever passed through a combustion pipe and having one end rotatably pivoted so as to cause the device to be operated under an irregular temperature. CONSTITUTION:In case that the device is normally operated, a shape memory alloy 14 is not heated to an irregular temperature, but is made free and indepen dent from a gas burner 4. An opening or closing of a gas nozzle 2 is performed under a curved condition of a bi-metal 7 for use in controlling a temperature. When a temperature is irregularly increased due to a poor control over tempera ture of the bi-metal 7 or the like, the shape memory alloy 14 is heated and its return operation to the stored shape is carried out. With this arrangement, a safety gas lever 13 is operated in a direction of Y to push down the gas nozzle 2 in a direction of B and the combustion is terminated. With this arrange ment, a safety characteristic of the device can be improved.
