Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically to an active electromagnetic vibration damping device for a portable oxygen concentrator compressor. Background Technology

[0002] A portable oxygen concentrator is a medical device that provides a high concentration of oxygen anytime, anywhere, primarily used to improve oxygen deficiency. It extracts oxygen from the air through physical or chemical means, helping people with respiratory illnesses or those in low-oxygen environments such as high altitudes maintain normal blood oxygen levels. The compressor vibrates when the concentrator is running.

[0003] Existing portable oxygen concentrator compressors often employ passive vibration damping technologies, such as spring dampers, rubber pads, or damping materials. These technologies achieve vibration reduction by absorbing or dispersing vibration energy, but they have limitations: poor adaptability: they cannot adjust damping parameters in real time according to changes in vibration frequency and amplitude, leading to a significant decrease in effectiveness during high-frequency or high-amplitude vibrations; low efficiency: passive vibration damping relies on the physical properties of the materials themselves, resulting in limited energy dissipation capacity, especially prone to resonance under continuous vibration conditions, and the vibration is transmitted to the product casing through the damping material; noise issues: residual vibration causes significant operating noise, affecting user experience. Currently, traditional passive vibration damping technology in portable oxygen concentrators can only achieve a minimum noise level of 45dB, thus necessitating an active electromagnetic vibration damping device for portable oxygen concentrator compressors to address these problems.
