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.

A system for detecting a possibility of boiling over and preventing said boiling over, the system comprising a vessel (101) having a lid (102), the lid (102) being characterised in that it is configured: to receive information on an initial level of a vessel content and a current level of the vessel content; and based on a difference between the initial level and the current level as well as the time of a creation of said difference: to instruct, by means of a controller (203), a height actuator (207) of the lid (102) to extend said lid (102) vertically, in order to extend the height of said vessel (101); and to instruct, by means of a controller (203), an aperture actuator (206) to create an aperture in a top of the lid (102) in order to facilitate exchange of heat.

A thermally sensitive control for controlling a power supply circuit to a heater in a liquid heating appliance is provided. The control includes a cordless connector part arranged to mate with a base connector part, first and second moveable electrical contacts mounted on first and second moveable members, and first and second thermally sensitive actuators. The control further includes a latch arm extending across the control between the moveable members, the latch arm including a first latch for the first moveable member and a second latch for the second moveable member, and a release member including a release part and a plunger, wherein the release member is resiliently biased to bring the release part into contact with the latch arm but the resilient bias is overcome when the plunger bears against a surface of the base connector part.

A continuous boiling water preparation method based on gas-liquid two-phase object detection comprises a flow regulator, a heater, a temperature sensor, a two-phase object detection sensor and a controller; the flow regulator is used for injecting a cold water flow obtained from the outside into a water inlet of the heater; the heater heats up according to heating power provided by the controller; the two-phase object detection sensor and the temperature sensor are connected behind a water outlet of the heater, and when a boiling water flow flows through the two sensors, a gas-liquid ratio signal and a temperature signal are obtained respectively, and transmitted to the controller; and the controller transmits a signal indicating required heating power to the heater or transmits a signal indicating a required flow value to the flow regulator through calculation to execute output after receiving the gas-liquid ratio signal.
