Description

Technical Field

[0001] The utility model relates to the technical field of noise reduction, in particular to a noise reduction device for an oxygen generator. Background Art

[0002] An oxygen generator is a kind of machine for producing oxygen, and its principle is to use air separation technology. First, air is compressed at high density and then the different condensation points of the components in the air are used to carry out gas-liquid separation at a certain temperature, and then rectification is carried out to separate it into oxygen and nitrogen.

[0003] The oxygen generation methods of oxygen generators can be simply divided into two types: physical methods and chemical methods. Among them, the oxygen generation by the molecular sieve pressure swing adsorption principle in physical oxygen generation is more widely used in the oxygen preparation work of household portable oxygen generators because of its stable performance and relatively high oxygen concentration produced. Using the molecular sieve pressure swing adsorption principle to generate oxygen requires a compressor to inject high-pressure gas into the cylinder filled with molecular sieve. However, during the operation of the compressor, vibrations will be generated, causing the oxygen generator to vibrate accordingly, and a large amount of noise will be generated due to the expansion of the supporting objects in contact. This results in a relatively large noise during the oxygen generation process.

[0004] At present, the noise reduction devices for oxygen generators in the prior art usually reduce noise by buffering and damping the vibrations generated by the compressor. When in use, due to the large demand for oxygen, the oxygen generator is frequently used. After long-term use of the internal damping structure of the noise reduction device, the damping and noise reduction effect becomes poor, and the damping structure needs to be replaced. There is a problem that the damping structure cannot be replaced conveniently. And when in use, the oxygen generator needs to be connected to the noise reduction device. However, during operation, the compressor generates vibrations, which easily causes the connection structure to become loose, and there is a problem that the oxygen generator and the noise reduction device cannot be stably connected.
