[0002] Oxygen is a simple substance formed by oxygen elements, with the chemical formula O2. Its chemical properties are relatively active. Most elements can react with oxygen. It is not very active at normal temperature and does not easily react with many substances, but it is very active at high temperatures and can directly combine with various elements. This is related to the fact that the electronegativity of oxygen atoms is second only to fluorine. Pure oxygen refers to oxygen with a purity of 100%.

[0003] For example, a high-purity oxygen preparation device with the publication number CN221015023U mainly realizes the adsorption, cleaning and clamping of particulate matter in the air by setting components such as adsorption sponges, fans, brushes, semi-gears, limit structures, arc-shaped blocks and motors, thereby prolonging the service life of the filter element and ensuring the stability of the air delivery pipe.
