Description

A kind of hydrogen-oxygen mixed gas generating device and method

technical field

The invention relates to the field of civil hydrogen preparation, in particular to a hydrogen-oxygen mixed gas generating device and method.

Background technique

As we all know, the human body is composed of cells, and human diseases can ultimately be attributed to cell damage. Human aging is also caused by cell aging or necrosis. The main culprit that causes cell morbidity or aging is excess oxygen free radicals. Oxygen enters the body through human respiration, and is transported to various cells by red blood cells in the blood, thereby generating oxygen free radicals. In order for it to produce energy in each cell, sugar and fat are burned and consumed. At this time, oxygen will also burn, and 2% of it will become active oxygen. Due to food additives, chlorine-containing drinking water and other reasons, the intestinal microbial flora is imbalanced, causing abnormal fermentation in the stomach and intestines. At this time, active oxygen will be produced in large quantities. In addition, after intense exercise, ultraviolet rays, smoking, drinking, hand electromagnetic radiation, mental stress, exposure to bacteria, viruses, air pollution, radiation, fluoroscopy, anticancer agents, dyes, etc., the human body will produce A lot of reactive oxygen species.

The hydrogen inhaler produces hydrogen by electrolyzing water, and the hydrogen molecules enter the human body directly from the respiratory system and diffuse to the nose, lungs and brain. After the hydrogen enters the human body, the hydrogen combines with the malignant oxygen free radicals in the human body and reduces it into water, which is excreted in the form of water. After eliminating the malignant free radicals, the human cells return to a balanced state. However, the oxygen produced by electrolyzed water is separated from hydrogen and cannot be absorbed by the user. The user can only absorb hydrogen and cannot absorb oxygen.
