The invention discloses a movable-type oxygen generator and a self-moving method therefor. The oxygen generator can comprise a housing, wherein one end of the housing is provided with an oxygen outlet; an oxygen generation unit which is disposed in the housing and is disposed at one side of the oxygen outlet; trundles which are disposed at the bottom of the housing and is used for moving the movable-type oxygen generator; a sensor which is used for collecting the real-time oxygen content data and real-time temperature data of each function region, and transmitting the data to a processor; the processor which is used for calculating an oxygen production coefficient and the oxygen generation data of each function region based on the real-time oxygen content data and real-time temperature data; a controller which is used for controlling an oxygen generation unit and a hub motor according to the oxygen production coefficient and the oxygen generation data; the hub motor which is used for driving the trundles to move; and a charging power supply which supplies power to the above parts. The oxygen generator achieves the self-moving through the real-time oxygen content data and real-time temperature data, releases the oxygen, and improves the application comfortableness for users.
