Description

Technical Field

[0001] This invention relates to the field of negative oxygen ions, and more specifically, to a negative oxygen ion spray solution produced using tropical rainforest vegetation resources, its preparation method, and its application. Background Technology

[0002] Negative air ions, also known as negative oxygen ions, are negatively charged oxygen ions that exist in the air. The indoor environments we live in usually contain low concentrations of negative oxygen ions, making them difficult to detect. However, in places like the seaside, forests, waterfalls, and grasslands, the air feels very fresh and breathing is particularly comfortable because the concentration of negative oxygen ions is high and easily perceived.

[0003] The concentration of negative oxygen ions in fresh air is 1000-1500 per cubic centimeter. 3 In suburbs, by the sea, in forests, near waterfalls, and on grasslands, the average number of negative oxygen ions reaches 3000 / cm³. 3 The above figures are generally lower than 600 negative oxygen ions / cm³ in indoor environments. 3 Negative oxygen ions can improve lung function. After inhaling negative oxygen ions for 30 minutes, the amount of oxygen absorbed by the lungs increases by 20%, and carbon dioxide is expelled by 15%. Negative oxygen ions can also improve myocardial function and sleep; they can activate various enzymes in the body, promoting metabolism; they can also alter the body's reactivity, activate the function of the reticuloendothelial system, and enhance the body's immunity; negative oxygen ions also easily adsorb bacteria, causing structural changes and energy transfer, leading to bacterial morbidity and death. Therefore, high concentrations of negative oxygen ions can improve human cardiopulmonary function.

[0004] Meteorologists believe that large cities like Beijing, with their continental climate, have fewer negative oxygen ions in the air compared to maritime climates. Coupled with severe air pollution, negative oxygen ions are easily absorbed and lost by pollutants such as smoke, dust, germs, and vehicle exhaust. Poor indoor ventilation further exacerbates this deficiency. Negative oxygen ions can be naturally generated under natural conditions such as cosmic rays and ultraviolet radiation, electrostatic forces, sunlight, photosynthesis, and illumination stimulation. They can also be artificially synthesized through corona discharge, thermionic emission from hot metal electrodes or photoelectrodes, radiation from radioactive isotopes, and ultraviolet irradiation.

[0005] Currently available negative ion concentrates are mainly produced using various chemical raw materials based on the principle of tip discharge. Although they do release negative ions, this method results in a lower concentration of negative ions, higher production costs, and more complicated construction. Furthermore, the chemical raw materials can easily cause secondary pollution, making them environmentally unfriendly. Summary of the Invention

[0006] The purpose of this invention is to utilize the artificial planting and ground-based resources of the tropical rainforest in Wuzhishan, Hainan, to provide a negative oxygen ion spray solution that can simulate the release of negative oxygen ions by vegetation, increase the concentration of negative oxygen ions in micro-spaces, improve the air quality of micro-spaces, and is green, environmentally friendly, and pollution-free.

[0007] Another objective of this invention is to provide a method for preparing a negative oxygen ion spray solution using tropical rainforest vegetation resources. By using a supercritical carbon dioxide extraction process, the effective components in the plants can be fully extracted to improve the ability of the spray solution to release negative oxygen ions.

[0008] The third objective of this invention is to provide an application of a negative oxygen ion spray liquid made from tropical rainforest vegetation resources. By spraying it on the surface of an object, a micro-space is formed around the head of a person, releasing negative oxygen ions. This fully utilizes negative oxygen ions and reduces their waste.

[0009] The technical problem solved by this invention is achieved by the following technical solution.

[0010] On one hand, embodiments of the present invention provide a negative oxygen ion spray solution produced using tropical rainforest vegetation resources, comprising the following raw materials by weight: 55-60 parts deionized water, 38-42 parts plant extract, 0.5-1 part polyvinyl alcohol, and 0.1-0.5 parts additives.

[0011] In some embodiments of the present invention, the following raw materials are included by weight: 60 parts deionized water, 42 parts plant extract, 1 part polyvinyl alcohol, and 0.5 parts additives.

[0012] In some embodiments of the present invention, the raw materials for the plant extract are five-needle pine needles from Wuzhishan, Hainan, camphor leaves, and Litsea cubeba seeds. These extracts are rich in negative oxygen ions near the plant tips, the mechanism being that air is ionized at the tips, and negative ions are repelled.

[0013] In some embodiments of the present invention, the additive is one or more of polyether-modified siloxane, silane coupling agent, and chlorinated polypropylene.

[0014] Negative oxygen ions in densely vegetated areas are mainly produced by electrons generated from the ionization of air due to electrical discharges at the tips of leaves and branches. The newly produced oxygen from plant photosynthesis readily accepts these electrons, thus forming negative oxygen ions. The chemical equation for photosynthesis is: 6CO₂ + 6H₂O → C₆H₂O 12O6 + 6O2. The vegetation coverage in the Wuzhishan area of ​​Hainan Province reaches as high as 85%, a significant reason for the region's negative oxygen ion concentration exceeding 5000. This invention provides a method to simulate the generation of negative oxygen ions in nature. Through an extraction process, solidified substances from the tips of these plants are extracted to form a concentrated adhering liquid with a solid content of 40%. In use, simply spraying the adhering liquid onto the surface of an object will cause the surface to form tips similar to vegetation, which discharge electricity into the air, thereby generating negative oxygen ions. The entire process uses no polluting components, and the concentration of the tips after application exceeds the concentration naturally generated in nature. Therefore, the application is simple and easy to operate, and the released negative oxygen ion concentration is very high and long-lasting, capable of stably and continuously generating negative oxygen ions for up to a year.

[0015] Pine needle extract is a relatively mature negative oxygen ion spraying technology in recent years. It mainly relies on the interaction of active ingredients such as flavonoids, terpenes, volatile oils, β-sitosterol, and riboflavin in plants with water molecules in the air to produce negative oxygen ions through photoelectric effect and ionization.

[0016] Hainan's tropical rainforests are rich in plant resources (both artificially cultivated and deciduous), and suitable plant species for making spray solutions include: five-needle pine, chicken feather pine, camphor tree, bamboo cypress, mountain litsea seed, five-finger peach, mugwort, wild large-leaf tea from Wuzhishan, aloe vera, and *Clematis chinensis*. Extensive experimental data research has shown that extracting and refining Hainan five-needle pine needles, camphor tree leaves, and mountain litsea seed in a specific ratio yields a relatively good long-lasting release effect of negative oxygen ions (up to 3 years or more).

[0017] Secondly, embodiments of the present invention provide a method for preparing a negative oxygen ion spray solution, comprising the following steps: S1. Collect five-needle pine needles, camphor leaves, and mountain licorice seeds from the Wuzhishan area, dry them, and then pulverize them to obtain ultra-fine powder. S2, the ultrafine powder from step S1 is extracted with supercritical carbon dioxide to obtain plant extracts; in this invention, supercritical carbon dioxide extraction technology is used to extract the above-mentioned ultrafine powder. Since the unsaturated double bonds of these compounds have the same bond energy as the carbon-carbon double bonds of carbon dioxide, the separation and enrichment of these compounds are accomplished by the formation and breaking of C-C bonds. That is, by utilizing the characteristic that the carbon atoms contained in the supercritical carbon dioxide solvent can form stable C-C chemical bonds with the carbon atoms in various compounds, the factors that can generate negative oxygen ion discharge are separated from the material.

[0018] S3. Place water, plant extracts, polyvinyl alcohol and additives in a homogenizing mixing tank, heat to 55-65℃, homogenize and stir for 1-2 hours, and then naturally cool to below 35℃ to obtain the spray solution.

[0019] In some embodiments of the present invention, in step S1, the material is pulverized and then passed through a 40-mesh sieve.

[0020] Thirdly, embodiments of the present invention provide an application of a negative ion spray solution, wherein the spray solution or a mixture of the spray solution and an antibacterial agent is sprayed onto the surface of an item. The negative ion spray solution provided by the present invention uses natural plant materials and is free of formaldehyde, benzene, xylene, and other volatile harmful substances, making it safe and environmentally friendly. This product can be diluted before use, and bactericides can be added to expand its applications.

[0021] In some embodiments of the present invention, the spray is applied to the inner surface of a head sleeping tent, a camping tent, or the surface of a pillowcase, or the inner surface of an eye mask, or the inner surface of a face mask.

[0022] The sleep tent provided by this invention has its internal materials treated with negative ion spraying, with one to three layers of negative ion spray liquid adhering to it. This creates a negative ion environment within the small tent, and tests have shown that the negative ion concentration inside the tent can reach up to 10,000 ions / cm³. 3 The above are all applicable, and the half-life is over six months. The tent material is any one of the following: silver-coated polyester fabric, polyester fiber soft fabric, PTT fiber soft fabric, cotton fabric, polyester-cotton blend fabric, nylon blend fabric, silk, or flocked fabric.

[0023] The tourist tent provided by this invention is made by spraying negative oxygen ion spray liquid onto the tourist tent through a spraying process of more than three times.

[0024] The pillowcase or pillow towel provided by this invention can be made by spraying negative oxygen ion spray liquid onto the pillowcase or pillow towel through a spraying process of more than three times.

[0025] The eye mask provided by this invention can be made by spraying negative oxygen ion spray liquid onto the eye mask through a spraying process of more than three times.

[0026] Compared with the prior art, the embodiments of the present invention have at least the following advantages or beneficial effects: The negative oxygen ion spray solution provided by this invention has plant extracts and water as its main components. The plant extracts can simulate the discharge of vegetation tips to generate negative oxygen ions, while water and polyvinyl alcohol serve as solvents to facilitate spraying.

[0027] The preparation method provided by this invention extracts plant tip solids using a supercritical carbon dioxide extraction process, forming a concentrated spray solution with a solid content of 40%. In use, the spray solution is simply sprayed onto the surface of an object, causing the surface to form tips similar to vegetation that discharge electricity into the air, thereby generating negative oxygen ions. This process uses no polluting components, and the concentration of the plant tip solids after application exceeds the concentration naturally occurring in nature. The application is simple and easy to operate, and the released negative oxygen ion concentration is high and long-lasting, stably and continuously generating negative oxygen ions for up to one year.
