Patent attributes
A temperature control apparatus has a housing and at least one thermosensitive protective action component. The thermosensitive protective action component has a metal actuator, an acting mechanism, a support frame, and a switch contact set. The metal actuator and the acting mechanism are both arranged on the support frame. The acting mechanism controls the on-off state of the switch contact set. The switch contact set is connected between the housing and the support frame. The switch contact set has a movable contact piece and a fixed contact piece. The temperature control apparatus also has a connecting component. The housing and the thermosensitive protective action component are flexibly connected therebetween via the connecting component. 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 and a temperature sensing surface of the liquid heater.
