Firstly: Anion purgative lighting is a kind of air purifier with lamp, which is a prefect innovative technique and is a bran-new humanized product. It could bring anion to purify air at the same time of illumination. It owns the function of anti-bacterium, air purification, and belongs to the tech field of non-metallic inorganic materials. Secondly: In normal atmosphere, gaseous molecule is always dissociative, and every molecule looks like electric-neuter. When outside complication act on gaseous molecule, the outer layer electron will get rid of the fetter from nucleus and spring out from orbit. And at this time, the gaseous molecule is in position of positive electricity, become positive- ion. And because of short free distance (10-8cm), the free electron is attached on some gaseous molecules or atoms, become air anion. Thirdly: Which benefit will be brought when anion act on body? 1. Influence to nerve system: inspiring spunk, improving efficiency and sleeping quality, reinforcing oxidative force of brain organization. 2. Influence to cardiovascular system: distending vas, releasing from artery vas convulsion, and get the goal of debasing blood pressure. And anion is helpful for improving heart function and nutrition of cardiac muscle. 3. Influence to blood system: Researches approve that anion have effect to slow blood fluxion, prolong cruor time, increase oxygen content in blood. 4. the most obvious influence to breath system: because anion enter into body through Respiratory tract infection, so, it could improve vital capacity.
