Description

Technical Field

[0001] The utility model relates to the technical field of oxygen-enriched diaphragms, and in particular to a micro oxygen-enriched diaphragm stacking component. Background Art

[0002] The oxygen-enriched membrane is an important component of the oxygen enrichment machine. The surface area of ​​the oxygen-enriched membrane should be selected according to the oxygen flow demand. For portable or small membrane oxygen enrichment machines, due to the space limitation of the whole machine, the surface area of ​​the oxygen-enriched membrane cannot be too large. This requires the use of a plurality of small-area oxygen-enriched membrane sheets in combination. However, the existing combination method of oxygen-enriched membrane sheets is to provide an air outlet on the frame of the oxygen-enriched membrane, and adopt a parallel connection method to realize the superposition and combination of multiple layers of membranes through a frame. The joints and frames of this structure occupy more space and are not suitable for portable and small oxygen generators.

[0003] After searching, China disclosed an oxygen-enriched diaphragm stacking module with patent publication number CN212581521U on February 23, 2021. It is roughly described as including several oxygen-enriched diaphragms, sealing gaskets and tubular oxygen-enriched collectors. A through hole is provided at the center of the oxygen-enriched diaphragm, a base is provided at the lower end of the oxygen-enriched collector, and several gas collecting holes are provided on the side walls of the oxygen-enriched collector. The oxygen-enriched diaphragm is mounted on the oxygen-enriched collector through the through hole, and sealing gaskets are installed on both sides of the through hole. An air outlet head is threadedly connected to the upper end of the oxygen-enriched collector, and an air outlet pipe is provided on the air outlet head. After assembly, the oxygen-enriched diaphragm and the sealing gasket are clamped between the air outlet head and the base, and the through hole is communicated with the gas collecting hole. Under the action of the vacuum pump, the outside air is sucked in from the surface of the oxygen-enriched diaphragm, sucked out from the through hole of the oxygen-enriched diaphragm, collected into the oxygen-enriched collector through the gas collecting hole and output from the air outlet head, which greatly shortens the airflow path and effectively reduces the volume of the component.

[0004] Although the above-mentioned prior art solution reduces the volume of the components, the oxygen-enriched diaphragm of the device is exposed to the outside and is easily damaged, which reduces the stability of the equipment. Utility Model Content
