Dual-system household oxygenerator

The utility model relates to a dual-system household oxygenerator which can provide users with oxygen continuously. The dual-system household oxygenerator utilizes air as raw materials and adopts molecular sieve pressure varying adsorption technology for generating medical oxygen, and a double-path compressor, an adsorption tower and a control system are adopted to meet requirements for continuous oxygen inhalation of patients. The dual-system household oxygenerator comprises a tank body, and two sets of independent oxygen generating devices are arranged in the tank body and both connected with an air source. Meanwhile, the two oxygen generating devices are connected with an oxygen storing cylinder which is connected with a humidifying cylinder. The two oxygen generating devices are both controlled by the control system. The dual-system household oxygenerator adopts the air as the raw materials without adding any additives or chemicals, replaces oxygen cylinders, and is capable of continuously generating medical oxygen and meeting the requirements for continuous oxygen inhalation of the patients. The dual-system household oxygenerator works in dual system circulation mode, ensures oxygen quality and prolongs service life.
