TECHNICAL FIELD
[0001] The utility model relates to a kettle technical field, especially a kettle anti -overflow structure. BACKGROUND
[0002] The working principle of the electric kettle is that the steam generated when the water boils deforms the bimetallic strip of the steam temperature sensing element, and this deformation pushes the power switch to turn off the power through the lever principle. The power-off is not self-resetting, so the kettle will not automatically reheat after power-off.
[0003] In the current electric kettle, if the water is added too full or the steam generated during heating is too much, it is easy to cause the water to overflow out of the kettle, splash to the table and the ground around the kettle, and also may cause electrical short circuit, scalding and safety hazards due to high-temperature boiling water splashing. The existing electric kettle has a press type anti-overflow structure designed at the kettle cover to close the passage from the kettle cavity to the spout during non-use, thereby avoiding the high-temperature steam from spouting out of the spout, but the press type structure has complex internal structure, high cost and needs to design multiple-stage metal spring assemblies, which has low service life in long-term humid environment.
