OXYGEN CONCENTRATOR

PROBLEM TO BE SOLVED: To provide an oxygen concentrator capable of achieving space saving while reducing a manufacturing cost.SOLUTION: A flow channel switching component 42, back flow prevention components 35 and 38, and a flow rate adjusting part 43 are disposed on a downstream side flow path 50 of the oxygen concentrator 11. The flow channel switching component 42 switches a communication path 41 connecting adsorption cylinders 34 and 37 between an open state and a closed state. The back flow prevention components 35 and 38 are provided to the adsorption cylinders 34 and 37 respectively, and prevent back flow of oxygen concentrated air. The flow rate adjusting part 43 adjusts a flow rate of the oxygen concentrated air flowing in the communication path 41. The oxygen concentrator 11 includes a manifold 61 formed by integrating all of the flow channel switching component 42, the back flow prevention components 35 and 38, and the flow rate adjusting part 43. The manifold 61 has a structure in which plate materials are laminated, and includes a flow channel inside.SELECTED DRAWING: Figure 1 【課題】製造コストを低減しつつ、省スペース化を図ることが可能な酸素濃縮装置を提供すること。【解決手段】本発明の酸素濃縮装置１１の下流側流路５０上には、流路切換部品４２、逆流防止部品３５，３８及び流量調整部４３が配置される。流路切換部品４２は、吸着筒３４，３７間を繋ぐ連通路４１を開状態または閉状態に切り替える。逆流防止部品３５，３８は、吸着筒３４，３７ごとに設けられ、酸素濃縮空気の逆流を防止する。流量調整部４３は、連通路４１を流れる酸素濃縮空気の流量を調整する。そして、酸素濃縮装置１１は、流路切換部品４２、逆流防止部品３５，３８及び流量調整部４３の全てを一体集積化してなるマニホールド６１を備える。マニホールド６１は、板材を積層した構造を有し、かつ内部に流路を備える。【選択図】図１
