Abstract
Description
[Technical field]
[0001] The present invention relates to the technical field of kettle, especially to an overflow prevention structure for a kettle. [Background technology]
[0002] The working principle of an electric kettle is that when water boils, the steam generated deforms the bimetallic piece of the steam thermosensor, and this deformation turns off the power switch by lever principle. The power off cannot be reset by itself, so the kettle will not automatically reheat after the power is turned off.
[0003] In the process of boiling water, if the current electric kettle is filled with water or generates too much steam during heating, the water will easily overflow the kettle and splash onto the table or ground around the kettle, and the hot water may splash, causing a short circuit in the electrical appliance or cause burns, which may pose a safety hazard. To solve the above problem, the conventional electric kettle is designed with a press-type overflow prevention structure on the kettle lid, which closes the passage from the kettle cavity to the kettle mouth when not in use, preventing high-temperature steam from escaping from the kettle mouth. However, the press-type structure requires a complex internal structure, high costs, and the design of a multi-stage metal spring module, which has a short lifespan in a long-term humid environment.
[0004] For this reason, the applicant has improved the overflow prevention structure and designed an overflow prevention structure for a kettle which can meet the needs of overflow prevention and has a simple structure. Summary of the Invention
