The invention belongs to the technical field of household appliances, and discloses a lifting type self-adaptive local heating electric kettle and a using method. The lifting type self-adaptive localheating electric kettle comprises a shell, an inner container, a kettle cover, a handle and an air escape valve. The inner container is fixedly connected into the shell in a sleeved mode. The kettle cover is inserted into an opening of the inner container, the air escape valve is installed in a hole in the middle of the kettle cover, a handle is welded to the right side face of the shell, an annular cavity is formed in the shell, a heating shell is welded to 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 the side wall, close to the inner container, of the heating shell. According to the lifting type self-adaptive local heating electric kettle, through the sectional design of the electric heating wire, a floating block is supported by utilizing the buoyancy of water, so that a contact piece can be communicated with a copper piece corresponding to the water level, the corresponding part of the electric heating wire works, the heating power is improved, targeted local heating is realized, the water boiling efficiency is improved, and the electric energy loss is reduced.
