OXYGEN CONCENTRATING DEVICE

摘要

An oxygen concentrating device easy to assemble and able to reduce production costs. The oxygen concentrating device (101) comprises a plurality of components including an adsorbing tube (102) storing adsorbent capable of selectively adsorbing nitrogen contained in material air, a storing tank (103) for temporarily storing concentrated oxygen gas generated in the adsorbing tube (102), a gas transferring means (104) for transferring material air, concentrated oxygen gas or exhaust gas, a solenoid valve (106) for opening/closing or switching a gas flow path connected to the adsorbing tube (102), and a control means (108) for controlling the gas transferring means and/or the solenoid valve, resin supports (109) for positioning and supporting the plurality of components at specified locations, and a plurality of resin covers (110) covering the outer sides of the supports (109), the supports (109) being formed by injection molding.
