A temperature control apparatus (100) and a liquid heater applying the temperature control apparatus (100). The temperature control apparatus (100) comprises a housing (10) and at least one thermosensitive protective action component (20). The thermosensitive protective action component (20) comprises a metal actuator (21), an acting mechanism (22), a support frame (23), and a switch contact set (24). The metal actuator (21) and the acting mechanism (22) are both arranged on the support frame (23). The acting mechanism (22) controls the opening/closing of the switch contact set (24). The switch contact set (24) is connected between the housing (10) and the support frame (23). The switch contact set (24) comprises a moving contact piece (241) and a fixed contact piece (242). The temperature control apparatus (100) also comprises a connecting component (30). The housing (10) and the thermosensitive protective action component (20) are movably connected therebetween via the connecting component (30). In the temperature control apparatus (100), as the housing (10) and the thermosensitive action component (20) are movably connected therebetween, when the liquid heater is deformed as a result of a thermal shock, a great thermal contact can be maintained between the thermosensitive protective action component (20) and a temperature sensing surface of the liquid heater, thus ensuring the reliability of temperature sensing. |
