Abstract
Official abstract text for this publication.
An oxygen concentrating apparatus includes an oxygen supply source, an attaching member, and a photodetector. An oxygen discharger is attached to the attaching member while oxygen from the oxygen supply source is supplied to the oxygen discharger. The photodetector is disposed in the oxygen concentrating apparatus and on an extension of an oxygen supply passage of the attaching member.
First claim
Opening claim text (preview).
The invention claimed is: 1. An oxygen concentrating apparatus comprising: an oxygen supply source; an attaching member, an oxygen discharger being attached to the attaching member while oxygen from the oxygen supply source is supplied to the oxygen discharger; an oxygen supply passage including at least a first passage formed in the attaching member; and a photodetector disposed in the oxygen concentrating apparatus and on a longitudinal axis of the first passage, the photodetector provided upstream along a flow direction of oxygen flowing in the first passage. 2. The oxygen concentrating apparatus according to claim 1 , wherein, in response to the photodetector detecting fire on the oxygen discharger, supply of the oxygen is stopped. 3. The oxygen concentrating apparatus according to claim 1 , wherein, an opaque transmission window is provided between the oxygen supply passage and the photodetector, the opaque transmission window allowing light to pass therethrough, and the photodetector includes an optical sensor detecting light through the transmission window, the optical sensor being capable of detecting an infrared region of light. 4. The oxygen concentrating apparatus according to claim 1 , wherein, the attaching member is made of metal and includes a temperature sensor. 5. The oxygen concentrating apparatus according to claim 1 , wherein, the oxygen supply passage includes a bent portion that is bent at a right angle, and an opaque transmission window is provided between the oxygen supply passage and the photodetector at the bent portion, the opaque transmission window allowing light to pass therethrough. 6. The oxygen concentrating apparatus according to claim 1 , further comprising a connecting member connected to the attaching member, the oxygen supply passage including at least the first passage and a second passage, the second passage linearly communicating with the first passage and being formed in the connecting member, and the photodetector being provided upstream along the flow direction of oxygen flowing in the second passage and the first passage in order. 7. The oxygen concentrating apparatus according to claim 2 , wherein, an opaque transmission window is provided between the oxygen supply passage and the photodetector, the opaque transmission window allowing light to pass therethrough, and the photodetector includes an optical sensor detecting light through the transmission window, the optical sensor being capable of detecting an infrared region of light. 8. The oxygen concentrating apparatus according to claim 2 , wherein, the attaching member is made of metal and includes a temperature sensor. 9. The oxygen concentrating apparatus according to claim 2 , wherein, the oxygen supply passage includes a bent portion that is bent at a right angle, and an opaque transmission window is provided between the oxygen supply passage and the photodetector at the bent portion, the opaque transmission window allowing light to pass therethrough. 10. The oxygen concentrating apparatus according to claim 3 , wherein, the attaching member is made of metal and includes a temperature sensor. 11. The oxygen concentrating apparatus according to claim 3 , wherein, the oxygen supply passage includes a bent portion that is bent at a right angle, and an opaque transmission window is provided between the oxygen supply passage and the photodetector at the bent portion, the opaque transmission window allowing light to pass therethrough. 12. The oxygen concentrating apparatus according to claim 4 , wherein, the oxygen supply passage includes a bent portion that is bent at a right angle, and an opaque transmission window is provided between the oxygen supply passage and the photodetector at the bent portion, the opaque transmission window allowing light to pass therethrough.
