Description

[Technical Field]

[0001] The present invention relates to the field of electric kettles, and more particularly to an electric kettle that prevents overflow when tilted. [Background technology]

[0002] Electric kettles are small household appliances commonly used in daily life for boiling water, and are popular among consumers due to their ability to boil water easily and quickly. Currently, when a typical electric kettle is tilted, the hot liquid inside the kettle can spill out, posing a risk of burns to the user. Existing electric kettles that prevent spillage due to tipping, such as a Chinese invention patent registered on April 21, 2023, with publication number CN218889548U, discloses a kettles with an exhaust passage connected to a drain passage. When the electric kettle is tilted, the press block assembly blocks the exhaust passage to prevent the liquid inside the kettle from spilling out.
