The invention provides a leak-proof kettle. The leak-proof kettle is mainly composed of a kettle body, an induction cooker, a tea tray, a water pump and a three-way solenoid valve. A kettle cover is fixed on a kettle body; in a water boiling process, a kettle nozzle of the kettle body is sealed through the kettle cover; the kettle body is put on the induction cooker and a water feeding key is pressed; the controller opens a normally closed end of the three-way solenoid valve and closes a normally open end of the three-way solenoid valve; the water pump is used for pumping water into the kettle body; in the water boiling process, the controller can be used for closing the normally closed end of the three-way solenoid valve and opening the normally open end of the three-way solenoid valve; after water is boiled, the kettle nozzle is covered through the kettle nozzle cover, so that generated steam forms relatively high steam pressure in the kettle body, and the steam only can downward pass through the normally open end of the three-way solenoid valve through a guide pipe to enter the water in a water accepting disc; almost steam is converted into the water in water with relatively low temperature; and only a small amount of the steam is overflowed out from the water accepting disc, so that the amount of the steam entering a room is effectively reduced after the water is boiled.
