Automatic switching device between standby oxygen equipment and oxygen generator

Abstract

This utility model relates to an automatic switching device between a backup oxygen supply system and an oxygen generator, belonging to the field of oxygen supply assurance technology. An intake valve B is installed at one end of the backup oxygen supply main pipe connected to a four-way connector. A connecting pipe A connects the main oxygen supply main pipe and the backup oxygen supply main pipe. Intake valves C and D are installed on the connecting pipe A. The third interface of the four-way connector is connected to the connecting pipe B. The other end of the connecting pipe B is connected to the connecting pipe A between intake valves C and D. A first gas pressure sensor is installed on the oxygen supply pipe. This utility model has the following advantages: it provides two different oxygen sources. When the oxygen generator malfunctions, it can automatically switch to the backup oxygen supply system. When the oxygen generator returns to normal, it can automatically switch back to the main oxygen generator. The backup oxygen supply system can guarantee daily oxygen use, ensuring a stable oxygen supply and meeting the hospital's oxygen needs.
