A temperature control apparatus 100 and a liquid heater applying the temperature control apparatus 100. The temperature control apparatus 100 has a housing 10 and at least one thermosensitive protective action component 20. The thermosensitive protective action component 20 has a metal actuator 21, an acting mechaism 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 on-off state 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 2 has a movable contact piece 241 and a fixed contact piece 242. The temperature control apparatus 100 also has a connecting component 30. The hosuing 10 and the thermosensitive protective action component 20 are flexibly connected therebetween via the connecting component. In the temperature control apparatus 100, as the housing 10 and the thermosensitive protective 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. |
