[0002] Oxygen generator is a type of machine that produces oxygen. Its principle is mainly based on air separation technology. It separates gas and liquid at a certain temperature and finally separates it into oxygen and nitrogen through distillation.

[0003] However, in the prior art, during use, the oxygen concentrator transports oxygen by directly plugging an external hose into the oxygen outlet pipe of the oxygen concentrator. However, the plug-in method only secures the connection through the friction between the pipes, which causes the external connecting pipe to be easily separated from the oxygen outlet pipe of the oxygen concentrator when being pulled by the user, resulting in the inability to stably transmit oxygen, reducing the stability of the oxygen concentrator and making it impossible to stably carry out the oxygen outlet work.

[0004] Therefore, we proposed a stable and efficient oxygen concentrator to solve the above problems. Utility Model Content

[0005] In view of the above problems existing in the existing stable and efficient oxygen concentrator, the present utility model is proposed.

[0009] The outer walls of the plurality of rotating plates are collectively sleeved with a pushing ring, and a movable limiting mechanism is provided between the pushing ring and the connecting ring.

[0010] Preferably, the movable limiting mechanism includes a push plate, which is in contact with and cooperates with the outer wall of the connecting ring and is fixedly connected to the connecting ring. A guide block is fixedly provided on the outer wall of the connecting ring. A guide groove is opened inside the push plate. The guide block is slidably arranged in the guide groove. A plug-in positioning mechanism is provided between the push plate and the connecting ring.

[0011] Preferably, the plug-in positioning mechanism includes an insertion rod, the outer wall of the connecting ring is provided with a plurality of spacing positioning grooves, the insertion rod is slidably passed through the interior of the push plate, the end of the insertion rod is inserted into the positioning groove, the rod wall of the insertion rod is provided with a spring, and the two ends of the spring are respectively fixedly connected to the insertion rod and the push plate.

[0012] Preferably, the longitudinal section of the guide block is T-shaped.

[0013] Furthermore, the insertion rod is an L-shaped insertion rod.

[0014] Preferably, the rod walls of the plurality of rotating rods are sleeved with torsion springs, and the two ends of the torsion springs are fixedly connected to the rotating rods and the connecting rings respectively.
