Generally, in order to prevent the phenomenon of liquid-free dry burning of the electric heater, a device which can automatically power off when the liquid-free dry burning is provided is provided therein. The safety device, that is, the temperature controller, uses a bimetal sheet as a temperature sensing element, and disconnects the dynamic and static contacts connected in series to the electric heating circuit through a linkage mechanism connected to the bimetal sheet, thereby powering off the electric heating element. Since the dynamic and static contact pieces may fail and cannot be disconnected after long-term use or under certain circumstances, it is necessary to set up a backup protection mechanism to disconnect the electric circuit of the electric heating element in another way. To this end, the British patent GB2181598 discloses a temperature controller with a backup protection mechanism, which includes a heat-sensitive action mechanism which is in thermal contact with the electric heating element and is connected with the contact piece pair as a control switch. When the electric heating element When overheating, the thermal action mechanism separates the contact piece pairs, thereby de-energizing the electric heating element; it also includes a backup protection mechanism, including a pre-compressed spring, and one end of which is connected to the switch contact piece through an operating member Pair or another set of switch contact pairs are connected. When the thermostat is in normal use, a fusible ejector pin against the other end of the spring to maintain it in a compressed state, and the other end of the fusible ejector pin is extended.
