Abstract
The invention relates to a liquid heating container. The liquid heating container comprises main body of container, heating device, connector for transfering electrical signal, electrical switching contact for connecting the power with the heating device, thermal control module for controlling the electrical switching contact. The heating device is at the lower end of the main body of the container and clings to the bottom of the main body. The thermal control module contacts with the heating device and is under the heating device. A projecting part which projects upwards is set at the bottom of the main body. The thermal control module comprises a touch device for turning on the electrical switching contact and the touch device is installed on the projecting part of the main body. When the liquid in the container is very few, even though the main body inclines, the projecting part firstly appears out from the liquid surface than the other parts of the bottom of the container, because the projecting part is not covered with the liquid, the temperature rapidly accends. After the touch device of the thermal control module in the projecting part takes into action, the electrical switching contact is directly or indirectly turned on, therefore the dry burn of the heating container is effectively prevented.
