Disclosed is a self-breathing electrochemical oxygenerator, comprising a housing. The housing comprises an upper housing part and a lower housing part. A cavity formed by the upper housing part comprises a battery installation chamber, a controller installation chamber and an electrochemical assembly installation chamber; batteries are installed in the battery installation chamber; a controller is installed in the controller installation chamber; a self-breathing electrochemical pure oxygen generation assembly is installed in the electrochemical assembly installation chamber; an upper housing part body of the upper housing part corresponding to the electrochemical assembly installation chamber is provided with breather holes; an upper housing part body of the upper housing part corresponding to the controller installation chamber is provided with a display screen assembling hole; and positive and negative poles of the battery installation chamber are connected to positive and negative poles of an access end of the controller by leads. By means of the electrochemical oxygenerator, after an external oxygen output pipe is blocked, through timely manual operation, pressure in the pure oxygen generation assembly is ensured to fall within a normal range, so as to ensure that the pure oxygen generation assembly works normally, thereby ensuring long service life of the oxygenerator.
