The invention provides an overturning type butting device used for supplying power to an electric kettle. The overturning type butting device includes a kettle body used for containing, heating and boiling drinking water and a power source base used for supplying power to the kettle body. The kettle body is movably and cooperatively connected with the power source base, and the power source base includes a supporting base used for supporting the kettle body, an overturning mechanism arranged on the supporting base and a power source component arranged on the overturning mechanism; the overturning mechanism is used for receiving downward pressure generated under cooperation between the kettle body and the supporting base and converting the downward pressure into an overturning force; the overturning mechanism includes a cylindrical outer drum with two open ends which are vertically formed; an overturning drum body is rotatably arranged in the outer drum body, an inner drum body is axially and movably arranged between the outer drum body and the overturning drum body along the outer drum body, overturning blocks parallel to the overturning drum body are axially distributed on the outer circular surface of the overturning drum body, and butting components used for pushing the overturning drum body to overturn are arranged on the end faces, close to the inner drum body, of the overturning blocks.
