Portable easy-to-install wearable ecological negative oxygen ion health device
Technical Field
The invention relates to an ecological health device, in particular to a portable and easy-to-install wearable ecological negative oxygen ion health device which provides a negative oxygen ion environment for a user.
Background
Air negative ions are also called negative oxygen ions, and refer to oxygen ions with negative charges for obtaining redundant electrons. The main components of the air are nitrogen, oxygen, carbon dioxide and water vapor, wherein the nitrogen accounts for 78%, the oxygen accounts for 21%, the carbon dioxide accounts for 0.03%, the nitrogen has no affinity for electrons, and only the oxygen and the carbon dioxide have affinity for electrons, but the oxygen content is 700 times of the carbon dioxide content, so that most of negative ions generated in the air are negative oxygen ions of the air. It is formed by combining free electrons with oxygen molecules in the air. The discharge (lightning) phenomenon, photoelectric effect, fountain, waterfall and the like in the nature can ionize the surrounding air to form negative oxygen ions. The smoke remains in the places where the smoke is diffused and the ventilation is poor for a long time, is often sleepy, dizziness, headache, nausea and the like, and is nearby a seashore, a waterfall and a fountain, so that people feel conscious and refreshing.
The negative ions have excellent effects of purifying and dedusting, reducing the harm of secondhand smoke, improving and preventing respiratory diseases, improving sleep, resisting oxidation, resisting aging, removing free radicals in the body and reducing blood viscosity, and the negative ions enjoy the American names of vitamin oxygen, air vitamins, longevity element, air vitamins and the like in the medical community.
Based on the fact that negative oxygen ions have indiscriminate benefits for human life and health, in recent years, negative ion related products are also different from negative ion therapeutic apparatuses, negative ion air purifiers, negative ion air conditioners and the like as spring bamboo shoots after raining, but due to the fact that the negative ion related products are huge in size and inconvenient to carry, pure negative oxygen ions with high concentration of respiratory tract can not be met anytime anywhere, high-quality air can not be provided for people anytime and anywhere, and the negative oxygen ion generators which are portable are also in recent market and in patent publications are mostly in a chest hanging mode, and are not attractive and inconvenient to wear due to being inconsistent with wearing habits of people. In addition, the existing chest-mounted negative oxygen ion generator is powered by a battery, cannot be grounded, and static electricity is formed by the accumulation of negative charges in the chest-mounted negative oxygen ion generator, so that the circuit board part of the product is likely to generate a static breakdown phenomenon, and the product is likely to break down.
At present, a wearable ecological negative oxygen ion generator is also available, but the wearable ecological negative oxygen ion generator adopts an integral plastic shell cavity to serve as a cap peak, has large weight, is not attractive enough in plastic cap peak, is unsightly, is not enough in human affinity of a hard plastic cap peak, and is not enough in consistency with a cloth cap body.
