Abstract
An oxygen generator for respiration-synchronized oxygen supply is provided. An ultrasonic gas sensor is used in the oxygen generator to act as a detection element for detecting human inhalation or respiration. On the basis of data corresponding to the human inhalation detected by the ultrasonic gas sensor, a control unit makes an oxygen generating unit supply oxygen to a human body through an oxygen delivery pipeline only when the human body inhales, and not supply the oxygen to the human body at the rest of time, thereby realizing respiration-synchronized oxygen supply. The respiration-synchronized oxygen supply by the oxygen generator is realized at low cost with simple and convenient control, thereby greatly reducing the cost, volume, weight, energy consumption and noise of the oxygen generator and increasing portability.
