Abstract

The invention provides an anti-rollover sealing device for an electric kettle lid. The device comprises a steam outlet arranged on the rear end of the kettle lid, a steam channel arranged on the side wall at the rear end of the kettle lid and a steam chamber communicating the steam outlet with the steam channel, wherein a conical cavity for the steam to pass is arranged at the bottom of the steam chamber and is internally provided with a sliding curved surface body; a cylindrical cavity which is sleeved downwards is sleeve jointed above the opening at the big end of the conical cavity; a guide plunger is sleeve jointed in an inner cavity at the upper end of the cylindrical cavity; and a cylindrical surface on the base of the guide plunger is movably contacted with a rolling curved surface body. The sealing device has the following beneficial effects: when the kettle rolls over, the rolling curved surface body slides to immediately push the guide plunger to slide forward to stop steam from entering into the passage of the steam chamber from the conical cavity, thus ensuring firm sealing and stopping leakage; and when the kettle is put in the normal position, a compression spring resets to push away the guide plunger to open the steam channel so that the steam enters into the steam chamber from a cross slot at the upper end of the guide plunger, one part of the steam enters into a temperature controlled switch via the steam channel and the other part of the steam is discharged from the steam outlet on the kettle lid, thus achieving the safe, accurate and reliable effects.
