Embodiment Construction

[0014] Below in conjunction with accompanying drawing and embodiment carry out further description:

[0015] see figure 1 , which is a structural schematic diagram of a pressurizable self-generating oxygen supply device of the present invention. The pressurizable self-generating oxygen oxygen supply device includes a respiratory monitor 1 , a self-generating oxygen reactor 2 , an electric control valve 3 , a dry ice heater 4 , and a control valve 5 . The self-generating oxygen reactor 2 is in communication with the dry ice heater 4, and an electric control valve 3 is arranged between the two for controlling the carbon dioxide of the dry ice heater 4 to enter the autogenous oxygen reactor 2. In addition, the parts where the autogenous oxygen reactor 2 and the dry ice heater 4 are connected to the electric control valve are located at the respective lower ends, so as to improve the effect of the autogenous oxygen reaction. The autogenous oxygen reactor is provided with KO2 rea...

Abstract

The invention belongs to the airborne oxygen system technology, in particular to a pressurizable self-generating oxygen supply device. The pressurizable self-generating oxygen oxygen supply device includes a breathing monitor (1), an autogenous oxygen reactor (2), an electric control valve (3), and a dry ice heater (4). The self-generating oxygen reactor (2) communicates with the dry ice heater (4), and an electric control valve (3) is arranged between the two, and the breathing monitor is respectively connected to the reaction inlet channel of the self-generating oxygen reactor (2). It is connected with the reaction outlet gas channel, and connected with the electric control valve (3) and the dry ice heater (4) respectively. The self-generating oxygen supply device of the present invention increases breathing monitoring and oxygen supply adjustment functions, and increases anti-suffocation and high-altitude pressurization and anti-load functions, which can be applied to oxygen supply for aircraft crews, and makes the aircraft oxygen system simpler and has greater practical application value.

Description

technical field [0001] The invention belongs to the airborne oxygen system technology, in particular to a pressurizable self-generating oxygen supply device. Background technique [0002] At present, the self-generating oxygen devices mainly include the catalytic decomposition of sodium chlorate (commonly known as oxygen candle) and the reduction reaction of potassium superoxide (KO 2 self-generating oxygen device) two. Oxygen candles are mainly used to supply oxygen to passengers of airliners. During operation, they supply pure oxygen continuously. The reaction process is uncontrollable, which does not meet the oxygen supply requirements of aircraft crews, and at the same time, it is easy to cause waste of oxygen sources. KO 2 When the self-generating oxygen device works, it supplies oxygen to the lungs, that is, the exhaled carbon dioxide and water vapor enter the reactor and react with KO2 to generate oxygen to supply oxygen to personnel. However, because the existing ...
