Vehicle carried oxygen making machine

The utility model discloses a vehicle carried oxygen making machine which relates to the configuration of an automobile assisted function. The vehicle carried oxygen making machine adopts a physical method to make oxygen. The 12V / 24V direct current power supply on the automobile is converted to the 220V alternating current power supply required by a working power supply of the oxygen making machine through a switch inverse power supply. Therefore, an entire technical design of the vehicle carried oxygen making machine is made. The automobile, as a modern means of transport, has advanced function day by day. However, so far the automobile has not the functional configuration of the vehicle carried oxygen making machine. The vehicle carried oxygen making machine comprises two big components of a switch inverse power supply and a variable-pressure adsorption oxygen making device. Two molecular sieve adsorption towers in the oxygen making device are used as main body devices. A circuit of the oxygen making device is engaged with an automobile circuit through the switch inverse power supply. The air is compressed into the molecular sieve adsorption tower by an air compressor driven by a series of automatic control circuits. A 5A molecular screen in the tower enriches the oxygen in the air under certain pressure, so that the vehicle carried oxygen making function is realized.
