[0002] At present, people have higher and higher requirements for the quality and user experience of oxygen concentrators in the field of oxygen concentrators. For users, each product has characteristics that affect its acceptance and demand, and users will judge the quality of the product by the noise of the machine. The compressor is the key moving core component of the oxygen concentrator and the main source of noise. The core cause of compressor noise is vibration. Vibration reduction components and vibration reduction systems are crucial to reducing the noise of the compressor. At present, many of the noise controls for the compressor inside the oxygen concentrator are limited to adding sound insulation measures, such as adding sound insulation cotton, etc. There is no particularly good way to deal with the noise generated during the vibration of the compressor. Therefore, it is urgent to provide a new shock-absorbing device that can achieve shock absorption during the operation of the compressor in the oxygen concentrator. Utility Model Content

[0004] Preferably, the shock absorbing device is an elastic element.

[0005] Preferably, the shock absorbing device comprises a spring, one end of the spring is mounted on the bottom corner of the compressor by means of a bolt, and the other end of the spring is arranged on the base.

[0006] Preferably, a mounting groove is provided on the base.

[0007] Preferably, the mounting groove is a cylindrical step mounting hole, and the mounting groove is concentric with the bolt.

[0008] Preferably, the bolt passes through the bottom angle of the compressor and the spring and penetrates into the interior of the spring. A spring fastening tube is installed on the bolt located inside the spring, and the spring fastening tube is used to fix the spring.

[0009] Preferably, a spring fixing groove is provided on the spring fastening tube, and a spring fixing portion is provided on the spring, and when the bolt is tightened to drive the spring fastening tube to fasten the spring, the spring fixing groove is locked with the spring fixing portion.

[0010] Preferably, a shock-absorbing pad is installed in the installation groove.

[0011] Preferably, the number of the bottom angles of the compressor is 4, the number of the springs is 4, and the 4 groups of springs are symmetrical in pairs.

[0012] Preferably, a compressor cover is provided on the outer side of the compressor.

[0013] Compared with the prior art, the advantages of this application are:

[0014] (1) In the present application, a shock absorbing device is provided between the compressor and the base, and the vibration and noise of the compressor are eliminated by the shock absorbing device, thereby improving the quietness of the oxygen concentrator.

[0015] (3) The spring is fixed by bolts and spring fastening tubes. When the bolts and spring fastening tubes are coaxial with the spring, not only can the spring be fixed, but also the shock absorbing effect is the best, avoiding lateral vibration and affecting the shock absorption effect. At the same time, the assembly is simple and the debugging is convenient.

[0016] (2) In this embodiment, a shock absorbing device is installed on the bottom corner of each compressor, and the other end of the shock absorbing device is fixed on the base of the oxygen concentrator. The overall vibration of the compressor is damped and noise-reduced by a separate shock absorbing device.
