The invention belongs to the technical field of household appliances and discloses a lifting-type self-adaptive local-heating electric kettle which comprises an outer shell, an inner container, a kettle cover, a handle and an air release valve. The inner container is fixedly socketed in the outer shell, the kettle cover is connected at an opening of the inner container in an inserted manner, the air release valve is mounted in a hole in the middle of the kettle cover, the handle is welded on the right side face of the shell, an annular cavity is formed inside the outer shell, a heating shell is welded on the side wall, close to the inner container, of the annular cavity, and an electric heating wire is arranged in an annular notch formed in one side wall, close to the inner container, of the heating shell. Through sectional design of the electric heating wire, a contact piece is enabled to be communicated with a copper piece corresponding to water level by utilizing buoyancy of water to jack up a floating block to realize working of a part corresponding to the electric heating wire, heating power is increased, targeted local heating is realized, water heating efficiency is improved, and electric energy loss is lowered.
