Qxygenerator, oxygenerator control system and method, and portable oxygen cabin system

The invention discloses an oxygenerator, an oxygenerator control system and method, and a portable oxygen cabin system. The oxygenerator comprises a first compressor, a second compressor, a first valve body, an oxygen generating device, an air filling pipeline and an oxygen filling pipeline, wherein the first compressor is communicated with the air filling pipeline to form a first air filling channel; a first air inlet, a first air outlet and a second air outlet are formed in the first valve body; the second compressor is connected with the first air inlet; the first air outlet is connected with the air filling pipeline; the second air outlet is connected with the oxygen pipeline through the oxygen generating device; the first valve body comprises a first working position and a second working position; when the first valve body arrives at the first working position, the first air inlet is communicated with the first air outlet, so as to ensure that the second compressor is communicated with the air filling pipeline to form a second air filling channel; when the first valve body is positioned at the second working position, the first air inlet is communicated with the second air outlet, so as to ensure that the second compressor is communicated with the oxygen filling pipeline through the oxygen generating device to form an oxygen filling channel. Therefore, the pressurization rate and the oxygen filling rate can be improved.
