Embodiment Construction

[0038] first reference figure 1 , the oxygen breathing apparatus 1 according to the first embodiment of the present invention is accommodated in a box body 10, and the box body 10 is closed by a bottom cover 20 on the bottom surface thereof. exist figure 1 On the right-hand side, the bottom cover 20 is connected to the box body 10 through a hinge 21 on one side. On the opposite side, the bottom cover 20 is secured to the case 10 by releasable clips 22 .

[0039] The clamp 22 is connected to the control unit 30 provided in the box body 10 through the signal line 23 . Through the signal wire 23, the clamp 22 can be released so that the bottom cover 20 opens under the force of gravity.

[0040] Further, a chemical oxygen generator 40 is disposed inside the tank 10 . Store chemicals in a chemical oxygen generator. Once activated by the chemical initiator 41, the chemical substances stored in the chemical oxygen generator undergo a chemical reaction, one of the products of whi...

Abstract

The invention relates to an oxygen breathing device, in particular for providing oxygen to passengers or crew of an aircraft, the device comprising an oxygen source, wherein oxygen is stored, in particular in chemically bound form or compressed form, an oxygen guiding device for guiding oxygen from the oxygen source to a person, and a control unit for controlling pressure and/or flow rate of the oxygen flowing through the guiding device. According to the invention, an improved oxygen breathing device is provided having an energy conversion and supply device which is adapted to convert energy stored or produced within the oxygen breathing device into an energy required by the control unit, and to provide said energy required by the control unit to the control unit.

Description

technical field [0001] The present invention relates to an oxygen breathing device, in particular for supplying oxygen to passengers or crew members of an aircraft, which device comprises an oxygen source in which oxygen is stored, especially in chemical bound or compressed form, a device for the Oxygen is directed from the oxygen source to the individual's oxygen guide, and a control unit for controlling the pressure and / or flow rate of the oxygen through the guide. Another aspect of the invention is a method for supplying oxygen to an individual and the specific use of the Peltier elements in the aforementioned oxygen breathing apparatus. Background technique [0002] Oxygen breathing apparatus of the above construction are used for many purposes in which a person must be supplied with oxygen either briefly or permanently. A particular field of application for this oxygen breathing device is the aircraft field, where the pressure drop inside the aircraft flying at high al...
