Description

Technical Field

[0001] This utility model belongs to the field of field oxygen supply technology, and specifically relates to a field central oxygen supply device with a convenient structure for adding or removing oxygen supply pipelines. Background Technology

[0002] Many traditional centralized oxygen supply systems employ heavy materials and large structures to ensure stability and safety. This places a burden on operators when moving the equipment in the field, increasing the difficulty of carrying and installing it. Secondly, existing devices typically integrate multiple functional modules, such as oxygen storage, delivery pipelines, and regulating valves. This multi-combination structure is not only bulky but also prone to interference between components during transport, making assembly and disassembly cumbersome and extending preparation time for field use. To address these issues, common practices include modular design or lightweight materials; however, these methods often face technical and economic limitations. For example, while modular design improves the adaptability of the equipment, it leads to increased manpower and time consumption for on-site assembly and commissioning. Therefore, we aim to design a novel field centralized oxygen supply device to solve this problem. Utility Model Content

The upper left and right middle of the oxygen concentrator body 100 are respectively hinged to a movable cover 160. In actual use, the lower end of the oxygen concentrator body 100 integrates various components for oxygen production. In actual use, the internal structure of the oxygen concentrator body 100 is the same as that of the VPSA system oxygen concentrator, which can meet the needs of multiple people to supply oxygen at the same time outdoors.

[0028] The movable cover 160 is hinged to the upper end of the hidden cavity 130 via a hinge, and the upper and outer sides of the movable cover 160 are respectively engaged with the upper and outer sides of the hidden cavity 130.

[0030] As the first embodiment of this utility model, by setting up an oxygen generator body 100 and a delivery component, the entire oxygen generator body 100 is integrated together in actual use. The upper end of the oxygen generator body 100 is also provided with a storage cavity 150, in which the oxygen delivery component 200 can be placed.
