| 摘要 |
The present invention relates to a switching apparatus in an oxygen generator (100), comprising a first switch valve (400) and a second switch valve (500). The first switch valve (400) comprises a case body (410) having a vertical wall (411) partitioning one inner end, horizontal materials (421, 426) installed at spaces partitioned by the vertical wall (411) respectively and having inflow holes (422, 427) and outflow holes (423, 428) through which air flows in and out respectively, first and second inhale tubes (431, 436) interconnected to the inflow holes (422, 427), respectively, an exhale tube (440) interconnected to the respective outflow holes (423, 428) in common, and an opening/shutting means opening and shutting the respective outflow holes (423, 428). The second switch valve (500) comprises a case body (510) having a vertical wall (511) partitioning one inner end, horizontal materials (521, 526) installed at spaces partitioned by the vertical wall (511) respectively and having inflow holes (522, 527) and outflow holes (523, 528) through which air flows in and out respectively, an inhale tube (530) interconnected to the respective inflow holes (522, 527) in common, first and second exhale tubes (541, 546) interconnected to the outflow holes (523, 528), respectively, and an opening/shutting means opening and shutting the respective outflow holes (523, 528), wherein the first and second switch valves (400, 500) are installed at an air inhale side and an air exhale side, respectively. |
