AI Technical Summary
Existing oxygen concentrators generate excessive noise during the air intake process, affecting user experience and comfort.
The oxygen generator incorporates a fluid divider and recessed areas on its surface, as well as a groove design on the intake pipe surface, to disrupt vortex formation, provide lateral diffusion space, and reduce vortex and turbulence noise.
It significantly reduces the intensity of eddies and turbulent noise generated by airflow friction with the pipe wall, improving user experience and equipment operating comfort.
