Embodiment Construction

[0017] The preferred embodiment of the present invention will be described in further detail below with reference to the accompanying drawings.

[0018] see figure 1 , figure 2 , an oxygen charging device, including a cabinet, two 40L standard oxygen cylinders 1 are placed side by side on the cabinet, and the outlets of the valves PF1 and PF2 of the oxygen cylinders are connected to the collector through high-pressure hoses R1 and R2, check valves Z1 and Z2. The trachea 3 is connected to each other, and after opening the valve PF1 or the valve PF2 alone or simultaneously opening the valve PF1 and the valve PF2, the high-pressure oxygen for medical or aviation breathing in the 40L standard oxygen cylinder enters the air collecting pipe 3, and the air collecting pipe is decompressed The valve J is connected with the buffer pipe 7, and the high-pressure oxygen in the gas collecting pipe is decompressed to about 0.4 MPa by the pressure reducing valve and then enters into the buf...

Abstract

The invention relates to an oxygenation device which comprises a cabinet. An oxygen storage tank is placed on the cabinet; an outlet of the oxygen storage tank is connected with an air collecting pipethrough a high pressure hose and a check valve; the air collecting pipe is connected with a buffer pipe through a pressure reducing valve; and the buffer pipe is connected with an oxygen compressor through a filter. According to the oxygenation device provided by the invention, high-pressure oxygen in a 40L standard oxygen bottle (or other big oxygen tanks) is decompressed to 0.4MPa so as to be fed into the oxygen compressor, and the oxygen is pressurized through the oxygen compressor so as to be filled into a portable small oxygen bottle, so that people can use for breathing in case of oxygen deficit; and the oxygenation device provided by the invention can be normally used at the altitude 5000m and below height, can be transported along with a vehicle or randomly, and can meet the actual use environment of a plateau area.

Description

technical field [0001] The invention relates to the technical field of emergency oxygen supply, in particular to an oxygen charging device, which is mainly used for oxygen charging of small portable oxygen bottles. Background technique [0002] Oxygen is the first substance for life support, and it is necessary to be equipped with life-guarantee oxygen in critical situations. In the field of aviation industry, civil aviation aircraft need to be equipped with emergency oxygen supply equipment to protect the lives of passengers when passenger planes are lost at high altitude; Oxygen supply to the crew; in the mining industry, the main cause of casualties is that people in distress cannot escape in time and die due to lack of oxygen. Mine rescue cabins and refuge chambers equipped with emergency oxygen supply equipment can provide life support for those who cannot escape the scene The system has become the necessary equipment for lifesaving in all kinds of mines in my country; i...
