Description
Technical Field
[0001] The utility model relates to the technical field of water collection, in particular to an air water collection device. Background Art
[0002] Clean water is an indispensable resource for human survival. The rapid development of industrialization will inevitably lead to the aggravation of water pollution, and clean water is becoming increasingly scarce. How to obtain clean water from the atmosphere has attracted extensive attention and research from researchers. Inspired by natural organisms, such as desert beetles, cacti, etc., which grow in water-scarce environments and use their own structures to achieve water collection from the air and thus survive in the desert. This phenomenon has inspired researchers, and various fog-catching and water-collecting devices have been studied and applied. Currently, the principles of water collection are mainly divided into two types. One is to use highly hygroscopic materials to absorb the moisture in the air and store it, and then use solar energy or other energy to evaporate and condense it to collect clean water. The other is to imitate beetles or cacti to construct a hydrophilic-hydrophobic composite structure, using the hydrophilic part to absorb the moisture in the air and the hydrophobic part to conduct away the collected water, so as to achieve the function of automatic water collection. The second principle does not require the assistance of other energy, is simple to operate and has low cost, and has higher application value. Currently, most of the construction of the hydrophilic-hydrophobic composite structure is achieved by finishing (spraying, screen printing, etching) hydrophilic substances on the hydrophobic surface, or by using the method of weaving hydrophilic-hydrophobic yarns. However, these methods have problems such as large processing difficulty and easy shedding of functional substances, resulting in failure, thus limiting their application.
[0003] Currently, the commonly used water collection methods mainly have the following problems:
[0004] (1) When using the spraying method to finish hydrophilic particles, such as TiO2, ZnO, etc., on the hydrophobic surface, the combination of the hydrophilic particles and the hydrophobic substrate is not firm, and it is easy to fall off after long-term use, and the uniformity is difficult to control;
[0005] (2) Screen printing hydrophilic substances or etching hydrophilic grooves on the hydrophobic surface has large processing difficulty and high cost;
[0006] (3) The materials woven from hydrophilic-hydrophobic yarns have problems such as mildew and easy damage after long-term use, and the service life is short. Content of the Utility Model

[0030] As Figure 1 and Figure 2 shown, the present utility model provides an air water collection device. The above air water collection device includes a card clothing substrate 1 and a plastic plate 2;
[0031] A plurality of needles 3 are uniformly distributed in a preset area on the first surface of the above card clothing substrate 1. The size of each of the above needles 3 is the same, and the height of the above needles 3 is a preset needle height; the thickness of the above plastic plate 2 is a preset thickness, and the above preset thickness is less than the above preset needle height. The size of the above card clothing substrate 1 is greater than or equal to the size of the above plastic plate 2; the above plastic plate 2 is compounded on the first surface of the above card clothing substrate 1. The part of the above needles 3 exposed from the above plastic plate 2 is the first needle, and the height of the first needle is the first height, and the first height is less than the above preset needle height. The present utility model compounds the card clothing substrate 1 and the plastic plate 2 to achieve automatic water collection of air.
[0032] Furthermore, the above card clothing substrate 1 is a hydrophilic metal card clothing, and the above plastic plate 2 is a hydrophobic soft plastic. The hydrophobic soft plastic can be a soft nylon material (PA) or a polyurethane material (PU).
[0033] Exemplarily, the size of the above preset area is a preset size, and the size of the above plastic plate 2 is greater than or equal to the above preset size.
[0034] Exemplarily, the center of the above card clothing substrate 1 coincides with the center of the above plastic plate 2.
[0035] Furthermore, as Figure 3 shown is a schematic diagram of a card clothing substrate 1 provided by the present utility model. A plurality of needles 3 are arranged on the first surface of the card clothing substrate 1 and in the preset area. When a hydrophobic soft plastic plate 2 (such asFigure 4 When the hydrophobic soft plastic plate 2 is compounded on the side of the hydrophilic metallic card clothing base plate 1 where the needle puncings 3 are provided, the hydrophobic soft plastic plate 2 needs to cover the range of the needle puncings 3.
[0036] Furthermore, the thickness of the bottom of the card clothing base plate 1 excluding the part of the needle puncings 3 can be 2 mm, and the thickness of the plastic plate 2 can be 2 mm.
[0037] Furthermore, the height of the needle puncings 3 on the card clothing base plate 1 can be 3 mm. After the card clothing base plate 1 and the plastic plate 2 are compounded, the height of the needle puncings 3 exposed from the plastic plate 2 is 1 mm.
[0038] In the present utility model, by compounding the plastic plate 2 on the side of the card clothing base plate 1 where the needle puncings 3 are provided, a part of the needle puncings 3 is exposed from the plastic plate 2. Since the needle puncings 3 have hydrophilic properties, they can collect moisture in the air, and the collected moisture condenses into water droplets on the needle puncings 3. Since the plastic plate 2 has hydrophobic properties, the condensed water droplets can flow down, thereby realizing moisture collection.
[0039] Exemplarily, the distance between any two adjacent needle puncings 3 among the above-mentioned multiple needle puncings 3 is a preset distance, and the above-mentioned preset distance is within a first preset numerical range.
[0040] Exemplarily, the diameter of the above-mentioned needle puncings 3 is a preset diameter, and the above-mentioned preset diameter is within a second preset numerical range.
[0041] Exemplarily, the above-mentioned first preset numerical range is 2 - 8 mm, and the above-mentioned second preset numerical range is 0.2 - 0.6 mm.
[0042] Furthermore, the distance between any two needle puncings 3 can be set to 5 mm to ensure that the distance between any two needle puncings 3 is within the first preset numerical range, preventing the collected moisture from spreading into a water film and being not easy to slide off, thereby affecting the water collection performance.
[0043] Furthermore, the diameter of the needle puncings 3 can be set to 0.4 mm. By setting the diameter of the needle puncings 3 within the second preset numerical range, the card clothing base plate 1 can be obtained through simple processing, thereby obtaining the air water collection device.
[0044] In the present utility model, by setting the distance between the needle puncings 3 on the card clothing base plate 1, it can effectively prevent the formation of a water film due to the too-close distance between the needle puncings 3, resulting in the droplets being not easy to slide into the collection device; by setting the diameter of the needle puncings 3 on the card clothing base plate 1, it can ensure that the card clothing base plate 1 can be effectively and simply compounded with the plastic plate 2, thereby successfully constructing a hydrophilic-hydrophobic composite structure and obtaining the air water collection device, enabling the automatic water collection of air through simple operations.
[0045] Exemplarily, the part of the plastic plate 2 penetrated by the needle punching 3 after the above plastic plate 2 is compounded with the above card clothing base plate 1 is the needle punching of the needle punching 3, and the size of the needle punching is equal to the size of the needle punching 3.
[0046] Exemplarily, the part of the above needle punching 3 located in the above needle punching is the second needle punching, and the height of the second needle punching is the second height.
[0047] Exemplarily, the sum of the above first height and the above second height is equal to the above preset needle punching height.
[0048] Exemplarily, the shape of the above needle punching 3 is a cylinder, and the cylinder includes two circular first surfaces and second surfaces, and the area of the first surface is smaller than the area of the second surface.
[0049] Further, when the plastic plate 2 is compounded with the card clothing base plate 1, the needle punching 3 on the card clothing base plate 1 can completely penetrate the plastic plate 2. After the compounding is completed, the needle punching 3 is divided into two parts. One part of the needle punching 3 exposes the plastic plate 2, and the other part of the needle punching 3 is completely embedded in the plastic plate 2.
[0050] Further, the shape of the needle punching 3 on the card clothing base plate 1 is a cylinder, and the upper part of the cylinder is a tip structure. The uppermost surface of the cylinder is the first surface, that is, the uppermost surface of the part of the needle punching 3 that exposes the plastic plate 2, and the surface at the bottom of the card clothing base plate 1 is the second surface. Among them, the area of the above first surface is smaller than the area of the above second surface.
[0051] In the present utility model, after compounding, a part of the needle punching 3 of the card clothing base plate 1 is exposed to the air. Since the needle punching 3 has hydrophilic properties, the moisture in the air can be collected through the needle punching 3.
[0052] Further, before compounding the hydrophilic metal card clothing base plate 1 with the hydrophobic soft plastic plate 2, it is necessary to perform hydrophilic treatment on the hydrophilic card clothing base plate 1 and hydrophobic treatment on the hydrophobic soft plastic plate 2 respectively.
[0053] Further, for the hydrophilic treatment of the hydrophilic metal card clothing base plate 1, 50% deionized water and 50% absolute ethanol can be used as a mixed solvent. 10 g of triblock copolymer silicone oil is added to the mixed solvent to prepare 100 g of hydrophilic functional finishing liquid. Subsequently, the metal card clothing (the size can be 10 cm * 10 cm) is completely immersed in the hydrophilic functional finishing liquid, taken out after 30 min, the excess moisture on the surface is drained, and then placed in an oven at 120 °C for baking for 10 min to obtain the hydrophilic metal card clothing base plate 1.
[0054] Further, for the hydrophobic treatment of the hydrophobic soft plastic plate 2, a C6 protective agent can be used as the hydrophobic finishing agent. 5 g of the C6 protective agent is added to water to prepare 100 g of the hydrophobic functional finishing solution. The soft nylon (PA, hardness 30D) is immersed in the hydrophobic functional finishing solution for 30 min. After immersion, the excess finishing solution on the surface is removed and then dried in an oven at 60 °C to obtain the hydrophobic soft plastic plate 2.
[0055] Further, the above-mentioned hydrophilized hydrophilic metal card clothing substrate 1 and the above-mentioned hydrophobized hydrophobic soft plastic plate 2 are compounded to construct a hydrophilic-hydrophobic composite structure, that is, an air water collection device, to achieve automatic water collection from the air.
[0056] In the present utility model, the two hydrophilic-hydrophobic functional materials are separately subjected to hydrophilic or hydrophobic treatment, and the hydrophilic metal card clothing substrate 1 and the hydrophobic soft plastic plate 2 can be obtained respectively. It can effectively avoid the performance repulsion on the material surface when treating multiple materials simultaneously, which may lead to poor treatment effects and affect the relevant properties of the materials.
[0057] In the present utility model, the hydrophilic card clothing and the hydrophobic soft material are directly compounded without the need for additional compounding processes. The operation is simple, the cost is low, and it can effectively achieve automatic water collection from the air.
[0058] In the present utility model, the metal card clothing is subjected to hydrophilic treatment, the soft plastic is subjected to hydrophobic treatment, and the soft plastic is compounded on the metal card clothing to construct a hydrophilic-hydrophobic composite structure, obtaining an air water collection device that is easy to obtain and has a low cost. It can effectively collect the moisture in the air and achieve automatic water collection from the air.
[0059] In an exemplary embodiment, the present utility model also provides a working principle of an air water collection device: the above-mentioned air water collection device includes a card clothing substrate 1 and a plastic plate 2. The metal card clothing is subjected to hydrophilic treatment to obtain the card clothing substrate 1; the soft plastic plate 2 is subjected to hydrophobic treatment to obtain the plastic plate 2; the plastic plate 2 is compounded on the side of the card clothing substrate 1 provided with the needles 3 to obtain a hydrophilic-hydrophobic composite structure. The needles 3 at the top collect the moisture in the air holes, and the collected moisture condenses into water droplets. The plastic plate 2 has hydrophobic properties, so that the condensed water droplets roll off, thereby enabling the collection of moisture and achieving automatic water collection from the air.
[0060] In an exemplary embodiment, as Figure 5 shown, the present utility model also provides a water collection performance testing device for an air water collection device. The above-mentioned testing device includes a test sample 4 (including the air water collection device provided in the above-mentioned embodiment of the present utility model), a support frame 5, a water collection box 7, and a water mist generator 6.
[0061] Exemplarily, the air water collection device in the above embodiment is fixed using the support frame 5, and a water collection box 7 is placed at the bottom of the air water collection device to collect the moisture in the air collected by the air water collection device. A water mist generator 6 is placed beside the air water collection device to simulate the moisture in the air.
[0062] Exemplarily, the above test device also sets up experimental control groups, namely the hydrophilized card clothing after hydrophilization treatment and the hydrophobic plastic after hydrophobic treatment.
[0063] Exemplarily, the diameter of the fog is set to be 1 - 10 μm, and the fog flow rate is 0.1 L / h. The hydrophilized metal card clothing, hydrophobic soft plastic, and hydrophilic-hydrophobic composite sample are respectively tested. The distance between the sample and the outlet of the water mist generator 6 is 7 cm and they are placed vertically. The water collected by the test sample 4 is collected by the container at the bottom. The test time is 2 h, and after completion, the weight of the collected water is weighed.
[0064] Exemplarily, as shown in Table 1, the weights of the water collected by different samples under the same test device are obtained. From the experimental results, it can be seen that under the same experimental conditions, the weight of the water collected by the hydrophilized card clothing is 1.2 g, the weight of the water collected by the hydrophobic plastic is 5.6 g, and the weight of the water collected by the hydrophilic-hydrophobic composite sample is 12.8 g. The hydrophilic-hydrophobic composite sample collects the most water and far exceeds the two control groups, showing strong air water collection performance. Among them, the weight of the water collected by the hydrophilized card clothing sample is less because the water mist directly spreads into a water film on the surface of the hydrophilized card clothing, resulting in the collected water being unable to slide into the water collection box 7.
[0065] Table 1 Comparison of water collection performance of different samples
[0066] Sample type Hydrophilic card clothing Hydrophobic plastic Hydrophilic-hydrophobic composite sample Weight of water collected (g) 1.2 5.6 12.8
[0067] The utility model tests the air water collection performance of the hydrophilized card clothing, hydrophobic plastic, and hydrophilic-hydrophobic composite sample through the water collection performance test device of the air water collection device, effectively proving the strong air water collection performance of the hydrophilic-hydrophobic composite sample, indicating that the air water collection device provided by the utility model can effectively realize the automatic water collection of air.

By simply compositing a hydrophilic card clothing substrate and a hydrophobic plastic plate, the present utility model constructs a hydrophilic-hydrophobic composite structure, which is simple in operation and low in cost, and effectively realizes the automatic water collection of air.
[0070] The above are the preferred embodiments of the present utility model. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and retouches can be made, and these improvements and retouches are also regarded as the protection scope of the present utility model.
