The invention relates to an electromagnetic heating type oxygen generation method and an oxygen generator. An oxygen candle or tablet is prepared from an oxygen candle oxygen-generating agent and putinto a container for heating by an electromagnetic heater, so the oxygen candle or tablet is decomposed and releases oxygen. According to the invention, an electromagnetic heating manner is employed to replace the traditional manner of heat release via metal powder in an oxygen candle formula, so an electric igniter or a bumping type igniter is not needed in the process of oxygen release, and thespeed of oxygen release is determined by the speed of electromagnetic heating; and an internal oxygen generating agent can be conveniently replaced, so the oxygen generator can be repeatedly used. Theelectromagnetic heating type oxygen generation method and the oxygen generator of the invention have the characteristics of a replaceable oxygen source, a rechargeable power source, portability, small size and light weight, and have broad development prospects in the fields of emergency lifesaving, health care, medical treatment, etc.
