Description

Technical Field

[0001] The utility model relates to the technical field of oxygen concentrators, in particular to a portable pulse oxygen concentrator with convenient replacement of molecular sieve components. Background Art

[0002] With the increasing pressure and accelerated pace of modern life, home oxygen concentrators have become a popular health product. Oxygen concentrators are machines that produce oxygen, utilizing air separation technology. First, air is compressed to a high density. The different condensation points of the air components are then used to separate the gas and liquid at a specific temperature. This is then distilled to separate the oxygen and nitrogen. Because they are often used to produce oxygen, they are often referred to as oxygen concentrators.

[0003] Oxygen therapy can improve the oxygen supply to the brain, relieve neural fatigue, maintain high energy, improve work and learning efficiency, reduce the harm to the body caused by pollution and harsh environments, and to a certain extent delay aging and enhance metabolism.

[0004] The molecular sieve components of pulse oxygen concentrators currently available require the main unit housing to be removed for replacement. When the molecular sieve reaches the end of its life and needs to be replaced, the user must return the entire unit to the manufacturer, which wastes user costs. Summary of the Invention
