NOISE-REDUCED OXYGEN GENERATOR SUPPLING STABLE OXYGEN CONTINUOUSLY TO THE INTERIOR

摘要

PURPOSE: Provided is a noise-reduced oxygen generator which is able to continuously supply stable oxygen to the interior by significantly reducing pulsating noise generated from a vacuum pump. CONSTITUTION: In an oxygen generator comprising a plurality of membranes(17), an oxygen induction pipe (20) inhaling oxygen separated by the membrane, a vacuum pump (18) compressing the inhaled oxygen and supplying required amount of oxygen to the interior and an oxygen exit pipe (22) supplying the compressed oxygen to the interior, a muffler (110) having a larger diameter than that of the oxygen exit type is mounted on the center of the oxygen exit type to reduce pulsating noise generated from the vacuum pump.
