Description

Technical Field

[0001] The utility model relates to the technical field of noise reduction of oxygen generators, in particular to a low-noise oxygen generator. Background Technique

[0002] As an essential gas for human survival, oxygen plays a very important role in daily life, especially in medical first aid. Usually, the prepared oxygen is stored in a steel cylinder at low temperature and high pressure for emergencies, but it is extremely inconvenient to use. Therefore, oxygen generators came into being. Oxygen generators can not only be used for medical first aid, but also regular oxygen inhalation by healthy people can promote blood circulation, clear the mind, eliminate fatigue, and effectively improve work efficiency. When an oxygen generator is performing oxygen generation operations, it usually generates relatively large noise pollution, and noise reduction and environmental protection operations are required.

[0003] An oxygen generator usually only has a simple noise reduction pad at the bottom to play a noise reduction role. However, in the actual use process, the existing oxygen generator has relatively insufficient noise reduction ability, and it cannot perform noise reduction and sound absorption operations on the noise during the operation of the oxygen generator with relatively high quality and level. The noise reduction ability is relatively insufficient, and the disassembly and assembly of the overall noise reduction structure are relatively inconvenient, the use convenience is not good enough, and the adaptability is relatively insufficient. For this reason, we propose a low-noise oxygen generator to solve the above problems. Content of the Utility Model
