Description

Technical Field

[0001] The invention relates to a device for gathering moisture in the air by imitating a fog basking beetle for drawing water, and belongs to the technical field of architectural art. Background Art

[0002] The Namib Desert Beetle, also known as the Mist Basking Beetle, belongs to the order Coleoptera, class Insecta, subclass Pterygota, and is generally black or dark brown in color. It is about 2 cm long, flat and hard, with a small head and hard wings on its back, called elytra. The elytra are large enough to cover the entire back of the body, and the secret of its adaptation to the extremely arid environment lies in the large elytra on its back. Through a microscope, it can be clearly seen that the surface of the elytra is covered with dense protrusions, which are randomly distributed at close range. The average diameter of each pockmark is 0.5 mm and the height is about 100 cm. Hundreds of microns, the average distance between pockmarks is 0.5-1.5 mm. Each pockmark is like a mountain peak, and the spaces between pockmarks are like valleys. The microstructures of peaks and valleys under a microscope are different, and they also exhibit different properties to liquids. Through special staining methods, scientists discovered that the valley area is covered with a waxy coat. Under a microscope, its microstructure is formed by regularly arranged flat hemispheres with a diameter of about 10 microns. This structure is similar to the surface of a lotus leaf, and exhibits hydrophobicity. So what is hydrophobicity? Here we need to first understand the concept of surface tension: surface tension is mainly because the molecules on the surface are subject to different forces between the molecules on the inside and outside. In layman's terms, the molecules on the surface of the liquid form a thin film. Due to the effect of surface tension, this film tends to be tightened, and this tendency will reduce the surface area of ​​the film as much as possible. That's why we observe that the shape of dewdrops is closer to a circle. This is because the surface area of ​​a sphere is the smallest under the premise of a certain mass. The closer the shape of the droplet on the contact surface is to a sphere, the stronger the hydrophobicity of the contact surface. Conversely, the stronger its hydrophilicity. Back to the surface of the elytra of the desert beetle, the mist beetle, the valley area is covered with a highly hydrophobic waxy coat, making it difficult for water droplets to stay on the surface, while the mountain area is not covered with this substance, the surface is smooth, showing a hydrophilicity that is completely opposite to the valley, and is easily wetted by water. It is precisely because of the simultaneous existence of two completely different structures, hydrophobic and hydrophilic, that it has mastered the skill of taking water out of thin air in the vast desert. Of course, the factors of time and place are also key. Here, we have to mention the unique geographical features of the Namib Desert. Due to the large temperature difference between day and night and frequent changes in air pressure, when the humid and hot waves in the sea pass over the Benguela Current and rush towards the desert, the humid and hot air condenses into fog when it encounters cold, making the Namib Desert the foggiest desert in the world. Desert beetles make full use of this opportunity. When the fog is thickest in the early morning, they will turn their heads down in the fog with their backs to the wind, and use their hydrophilic peaks to absorb moisture from the fog, gradually forming water droplets. When they accumulate to a certain level, the water droplets will slide effortlessly along the hydrophobic valley and flow to the beetle's mouth. Scientists have found through observation that if the temperature, humidity and body temperature of the beetle are particularly suitable, the beetle can drink water equivalent to 40% of their body weight in one morning, which is about 3.2 ml.Inspired by the Namib Desert Beetle, a new type of nano-coating material has been developed to replace the previous energy-intensive condensing equipment and provide water sources for deserts and other arid areas. The surface of this special coating material is similar to the elytra of desert beetles. Scientists deposited polytetrafluoroethylene nanoparticles on a super-hydrophobic copper mesh to imitate the pockmarked texture on the surface of desert livestock elytra, and combined it with a hydrophilic copper sheet to form a mixed surface. The tiny water droplets in the mist can be gathered through the hydrophilic surface, and the hydrophobic surface can timely let the large water droplets formed by the gathering slide down, thereby realizing water collection. Scientists imitated this special function and developed a series of water-drawing devices, such as water-drawing roof tiles, special water-drawing tents, and automatic water-storing kettles, which greatly alleviated the problem of fresh water acquisition in water-scarce areas. As an important supplement to the production method of drinking water, it provides more clean and reliable drinking water sources for humans. Of course, the blueprint that humans have learned from nature is far more than just a small beetle. With the development of human civilization, new technologies developed under the inspiration of biology are changing our lives step by step. Scientists have been conducting research in various revolutionary ways. They have broken the barriers between biology and engineering and are producing some remarkable and even world-changing research results. Titanium dioxide is an inorganic substance with non-toxicity, excellent opacity, good whiteness and brightness. It is widely used in sunscreens. Its sunscreen mechanism is mainly to absorb and scatter ultraviolet rays. The blocking of medium-wave ultraviolet rays is mainly absorption, and the blocking of long-wave regions is mainly scattering. Its ultrafine product nano-titanium dioxide has more superior performance and is used in the research and development of new and high-quality sunscreen cosmetics. Nano-titanium dioxide can absorb ultraviolet rays, reflect and scatter ultraviolet rays, and can also transmit visible light. It is a physical shielding type ultraviolet protection agent with superior performance and great development prospects. Grafting reaction refers to the copolymerization reaction of forming graft copolymers. This copolymer is formed by two different polymer chains connected by chemical bonds and has the comprehensive properties of two polymers. On August 26, 2023, Thomas M. Schutzius and other researchers from the Swiss Federal Institute of Technology in Zurich (ETH Zurich) developed a method to efficiently collect water from fog and simultaneously degrade organic pollutants (Photocatalytically reactive surfaces for simultaneous water harvesting and treatment. Ritwick Ghosh, Adrien Baut, Giorgio Belleri, Michael Kappl, Hans-Jürgen Butt & Thomas M. Schutzius, Nature Sustainability, 2023, DOI: 10.1038 / S41893-023-01159-9).The core of their design is a wire mesh coated with anatase titanium dioxide nanoparticles wrapped in a polymer matrix. Once activated by sunlight, the photoactivated titanium dioxide layer will continue to decompose organic molecules such as diesel and bisphenol A for hours even in the absence of sunlight, and can work on foggy and cloudy days and at night; in addition, the wet surface of the mesh also improves the efficiency of water extraction. In outdoor experiments, the device can maintain good water collection performance for a long time, and the water treatment efficiency is greater than 85%. The device does not require additional energy and can achieve continuous production of purified water, providing a promising solution to the shortage of freshwater resources. The authors designed two photocatalytic reaction coatings, one hydrophilic and one hydrophobic. For the former, titanium dioxide (TiO. 2 ) nanoparticles were embedded in a polyvinyl butyral (PVB) matrix grafted with a polydimethylsiloxane (PDMS) brush; for the latter, the composition was similar except that PVB was replaced with ethyl cellulose (EC). They deposited these coatings on glass substrates and silk screens and activated them by exposing them to a UV light source before testing their ability to degrade organic matter. They dropped water droplets containing methyl orange (initial concentration 25 ppm, volume 5 μL) on the active TiO 2 -PVB-PDMS and TiO 2 -EC-PDMS coating, it can be seen that the water droplets changed from light orange to clear after 30min and 250min, respectively, indicating that the organic pollutants were decomposed. In addition, they also studied the TiO 2 -PVB-PDMS reactive coatings to treat real organic pollutants, namely diesel and bisphenol A. They used UV light to irradiate TiO 2 -PVB-PDMS coated culture dishes, and then dripping 100μL of water-diesel emulsion (initial concentration of diesel in water 0.75ppm), after 30min of contact, the concentration value decreased by 99.9%; while for 3000μL of water-bisphenol A mixture with initial concentration of 0.15ppm, the concentration of bisphenol A gradually decreased over time and could not be detected after 30min. Interestingly, TiO 2 -PVB-PDMS coating is hydrophobic before UV activation and becomes hydrophilic only after UV irradiation. 2 -EC-PDMS coatings are hydrophobic before and after activation by UV irradiation. Using epifluorescence microscopy, the authors also explored the effects of wettability and droplet volume on the time required for a single droplet to degrade pollutants, and explained the results obtained using a "diffusion-adsorption-reaction" model, in which hydrophobic and hydrophilic reactive coatings belong to diffusion-limited and adsorption-limited mechanisms, respectively. The authors added TiO at the maximum concentration in the active coating. 2Photocatalytic nanoparticles, while also taking into account good coating adhesion, they introduced a large number of active sites to achieve minimal water treatment time. When deposited on a mesh substrate, they found that with TiO 2 Compared with the EC-PDMS reaction coating, TiO 2 -PVB-PDMS reactive coatings have better fog collection and water treatment effects, probably because the latter has a smaller droplet contact angle and a shorter pollutant diffusion length. These speculations are supported by experimental and theoretical results of high-speed imaging and processing time. Then, they conducted outdoor tests, and under high UV index conditions (sunny days), TiO 2 The water treatment efficiency of the -PVB-PDMS reaction network exceeds 90%. When the UV index is zero (cloudy day), its water treatment efficiency can still reach 85%, thus proving the application prospects of the technology. 2 -PVB-PDMS reaction coating has a good function of absorbing moisture in the air. Therefore, how to design and manufacture a water collection device that can quickly and efficiently absorb moisture in the air and have the function of collecting moisture, so that people can use the collection device to automatically collect moisture from the air, has become a major problem that needs to be solved urgently. Therefore, using TiO 2 -PVB-PDMS and wax layered settings, the structure and composition characteristics of the elytra of the bionic fog beetle, design a water collection device that can quickly absorb and gather moisture from the air, and ultimately achieve the purpose of quickly absorbing and gathering moisture from the air. It is necessary to invent a bionic fog beetle water-collecting device in the air. Summary of the invention

[0004] The technical solution adopted by the present invention to solve its technical problem is:

From top to bottom, the thickness of the water-collecting coating 8 gradually increases. The lower part of the water-collecting coating 8 is connected to the hydrophilic material layer 4 to form a whole. The thickness of the thinnest part of the upper end of the water-collecting coating 8 is 1 / 4 of the thickness of the thickest part of the lower end.

When setting, use A multi-nozzle spray gun with a nozzle diameter of 9.9-10.1 microns sprays the waxy hydrophobic material intermittently on the upper surface of the diaphragm cushion layer 5. Each time the waxy liquid is sprayed, a waxy hemisphere is formed on the upper surface of the diaphragm cushion layer 5, thereby forming a regularly arranged flat hemisphere similar to the surface of a lotus leaf on the surface between the two water-absorbing protrusions 1. The diameter of the flat hemisphere is 9.9-10.1 microns; the diaphragm cushion layer 5 is located between the hydrophilic material layer 4 and the hydrophobic material layer 6.

The water-absorbing protrusion 1 has a diameter of 0.5 mm and a height of 100-900 μm. The distance between two adjacent water-absorbing protrusions 1 is 0.5-1.5 mm. The sharp protrusion 7 is a conical structure in the center of the water-absorbing protrusion 1. The bottom surface of the sharp protrusion 7 is circular with a diameter of 0.5 mm. The bottom surface of the sharp protrusion 7 is located on the upper surface of the substrate layer 3, where the sharp protrusion 7 and the substrate layer 3 are integrated; the water-collecting material coating 8 is a thin layer formed by the coating on the surface of the sharp protrusion 7. From top to bottom, the thickness of the water-collecting material coating 8 gradually increases. The lower part of the water-collecting material coating 8 is connected to the hydrophilic material layer 4 to form a whole, and the upper end of the water-collecting material coating 8 is the thinnest. The thickness at the bottom is 1 / 4 of the thickest thickness at the bottom. The upper end of the water-collecting material coating 8 surrounds the top of the sharp protrusion 7 and is 1-2 microns away from the top of the sharp protrusion 7. The surface between the two water-absorbing protrusions 1 is the upper surface of the hydrophobic material layer 6. The hydrophobic material of the hydrophobic material layer 6 is wax. When setting, a multi-nozzle spray gun with a nozzle diameter of 9.9-10.1 microns is used to intermittently spray the waxy hydrophobic material on the upper surface of the diaphragm cushion layer 5. Each time the wax liquid is sprayed, a wax hemisphere can be formed on the upper surface of the diaphragm cushion layer 5, thereby forming a regularly arranged flat surface similar to the surface of a lotus leaf on the surface between the two water-absorbing protrusions 1. The shape of the flat hemisphere is 9.9-10.1 microns in diameter. Since the wax is hydrophobic, the newly formed hydrophobic material layer 6 exhibits hydrophobicity. The diaphragm cushion layer 5 is a thin layer of hydrophobic material attached, located between the hydrophilic material layer 4 and the hydrophobic material layer 6. The diaphragm cushion layer 5 is made of polyethylene plastic material with a thickness of 0.1-0.2 mm. The exposed convex hole 2 is a circular hole at the diaphragm cushion layer 5 corresponding to the water-absorbing convex 1, with a diameter of 0.5 mm. Since the hydrophilic material layer 4 has a certain thickness, the lower edge of the exposed convex hole 2 is located at the height of the thickness of the hydrophilic material layer 4 on the upper surface of the substrate layer 3, and is on the inner surface of the exposed convex hole 2. There is a certain space between the surface and the pointed protrusion 7 so that the hydrophilic material of the water-collecting material coating 8 can pass through, connecting the water-collecting material coating 8 and the hydrophilic material layer 4 together to form a whole; the hydrophilic material layer 4 is a water-absorbing layer formed by the hydrophilic material between the diaphragm cushion layer 5 and the substrate layer 3, wherein the hydrophilic material is made of titanium dioxide TiO2 nanoparticles embedded in a polyvinyl butyral PVB matrix grafted with a polydimethylsiloxane PDMS brush, referred to as TiO2-PVB-PDMS, and the hydrophilic material is brushed on the upper surface of the substrate layer 3 to form the hydrophilic material layer 4, and the thickness of the hydrophilic material layer 4 is 0.05-0.1 mm, with hydrophilicity: When setting up the air moisture collection device that simulates the water absorption of the fog beetle, firstly, the TiO2-PVB-PDMS hydrophilic material is brushed on the upper surface of the substrate layer 3 and the surface of the sharp protrusion 7, and the hydrophilic material layer 4 is made on the upper surface of the substrate layer 3, and the water collection material coating 8 is made on the surface of the sharp protrusion 7; then, the exposed protrusion hole 2 of the diaphragm cushion layer 5 is made to correspond to the water absorption protrusion 1, and the water absorption protrusion 1 is inserted into the exposed protrusion hole 2. Since the TiO2-PVB-PDMS hydrophilic material is relatively soft, Some of the hydrophilic material slides down into the hydrophilic material layer 4 under the action of its own gravity, so that the water collection material coating 8 gradually thickens from top to bottom. Then, the wax hydrophobic material is intermittently sprayed on the upper surface of the diaphragm cushion layer 5 using a multi-nozzle spray gun with a nozzle diameter of 9.9-10.1 microns to form a hydrophobic material layer 6. After drying with hot air from a hair dryer, a bionic fog beetle water collection device in the air can be made, so that it can be used in various devices that need to collect water in the air to collect and utilize water in the air. .
