Description

Technical Field

[0001] The present invention relates to the field of hydrogen preparation for civilian use, and in particular to a hydrogen-oxygen mixed gas generating device and method. Background Art

[0002] As we all know, the human body is composed of cells. Human diseases can ultimately be attributed to cell damage, and human aging is also caused by cell aging or necrosis. The main culprit for cell pathology or aging is excess oxygen free radicals. Oxygen enters the body through human breathing and is transported to each cell through red blood cells in the blood, thereby generating oxygen free radicals. In order for it to generate energy in each cell, sugar and fat will be burned and consumed. At this time, oxygen will also burn, and 2% of it will become active oxygen. Due to food additives, chlorine-containing beverages and other reasons, the intestinal microbial flora is imbalanced, causing abnormal fermentation in the stomach and intestines, and at this time, active oxygen will be produced in large quantities. In addition, after intense exercise, ultraviolet rays, smoking, drinking, electromagnetic radiation from hands, when mental stress is high, contact with bacteria, viruses, air pollution, radiation, perspective, anticancer agents, dyes, etc., a large amount of active oxygen will be generated in the human body.

[0003] The hydrogen inhaler produces hydrogen by electrolyzing water. Hydrogen molecules enter the human body directly from the respiratory system and diffuse to the nose, lungs and brain. After hydrogen enters the human body, it combines with the malignant oxygen free radicals in the human body and is reduced to water, which is discharged from the body in the form of water. After eliminating the malignant free radicals, the human cells return to a balanced state. However, the oxygen produced by electrolyzing water is separated from the hydrogen and cannot be absorbed by the user. The user can only absorb hydrogen but not oxygen. Summary of the invention

[0030] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0031] An embodiment of the present invention provides a hydrogen-oxygen mixed gas generating device for generating a hydrogen-oxygen mixed gas, wherein the hydrogen-oxygen mixed gas is composed of hydrogen and oxygen, the volume percentage of hydrogen is A, the volume percentage of oxygen is B, and B=20% to 21%.

[0032] The hydrogen-oxygen mixed gas generated by the electrolysis device of the present invention contains hydrogen and oxygen, and not only has the function of a hydrogen respirator, but also has the same oxygen content as that of air, and can meet the human body's demand for oxygen.

[0033] It should be noted that an explosion will occur when the volume ratio of air to hydrogen is about 5:2, and the most violent explosion occurs when hydrogen and oxygen react in a volume ratio of 2:1. The volume fraction of oxygen in the air is 21%, and the volume ratio of air to hydrogen required for the reaction is about 5:2. At this time, the volume fraction of hydrogen is at the upper and lower limits, and both are weak explosions. Beyond this range, hydrogen will not explode at all.

[0034] The ratio of hydrogen to oxygen in the hydrogen-oxygen mixed gas of the present invention is far beyond the explosion range, so it is safe and reliable.

[0035] In order to ensure that the ratio of hydrogen to oxygen in the hydrogen-oxygen mixed gas meets the requirements and that the ratio of the two is not within the explosion range during the preparation process, such as Figures 1 to 3As shown, the electrolysis device of the present invention comprises a first electrolytic cell 1 and a second electrolytic cell 2, wherein water is introduced into the first electrolytic cell 1 for a first electrolysis to generate hydrogen with a content of a1 and oxygen with a content of b1, and the hydrogen and humid air generated by the first electrolytic cell 1 are introduced into the second electrolytic cell 2 for a second electrolysis to generate hydrogen with a content of a2 and oxygen with a content of b2, wherein the oxygen content in the humid air is b3, a1+a2=A, b2+b3=B, and in order to ensure safety and better control the ratio of hydrogen and oxygen, the oxygen generated by the first electrolytic cell 1 is discharged from the electrolysis device.

[0036] Since the electrolysis capacity of the first electrolytic cell 1 is limited, the hydrogen content it produces only accounts for 60% to 70% of the hydrogen-oxygen mixed gas, that is, a1 = (60% to 70%) * (A + B). In order to increase the proportion of hydrogen in the hydrogen-oxygen mixed gas, the present invention requires a second electrolytic cell 2 to perform secondary electrolysis to increase the hydrogen content.
