Problems solved by technology

In order to adapt to the plateau environment, the existing method is to use a compressor with a larger flow rate, but this method will not only increase the cost, but also increase energy consumption. At the same time, due to the excessive flow rate of the compressor when used in plains, it is easy to cause adsorption The air intake breakdown phenomenon of the unit, resulting in a rapid drop in oxygen concentration

Abstract

The invention relates to a portable oxygen generator self-adaptive to altitude and an oxygen generation method. The oxygen generator comprises a compressor, an oxygen generation unit, an oxygen buffertank and a control unit, wherein a flow sensor is arranged behind the compressor; the compressor and the flow sensor are connected with the control unit; the flow sensor is used for monitoring the output flow value of the compressor in real time and transmitting an output flow value to the control unit; a compressed air flow threshold value required by a current oxygen production amount is storedin the control unit; the control unit is used for receiving the output flow value, monitored in real time, of the compressor, comparing the output flow value with the compressed air flow threshold value, and conducting PID closed-loop feedback according to a comparison result to adjust the rotating speed of the compressor until the output flow value is matched with the compressed air flow threshold value. According to the invention, the problems of insufficient flow of the compressor caused by elevation of the altitude and inflow air breakdown of the oxygen generation unit caused by overlargeflow of the compressor due to reduction of the altitude can be fundamentally solved, and self-adaption to altitude is realized.

Description

technical field [0001] The invention relates to the technical field of household oxygen generators, in particular to a portable oxygen generator and an oxygen generator method that adapt to altitude. Background technique [0002] At present, portable oxygen concentrators are more and more widely used in high-altitude areas, but as the altitude rises, indicators such as oxygen production or oxygen concentration of Pressure Swing Absorption (PSA) oxygen concentrators will decrease, and altitude The decline is more obvious at altitudes above 3000 meters. The reason is that due to the increase in altitude, the atmospheric pressure decreases, the air becomes thinner, and the exhaust volume of the compressor is reduced. Therefore, the oxygen production or oxygen concentration will increase with the altitude. increasing and gradually decreasing. In order to adapt to the plateau environment, the existing method is to use a compressor with a larger flow rate, but this method will no...
