Daytime desorption: During this time, the second and third valves are closed. During the day, the solar collector tubes heat up under sunlight, thereby desorbing moisture from the moisture-absorbing material. Moisture evaporates, and the gas carrying the evaporated moisture sequentially enters the condenser through the base box and the first pipeline. The evaporated moisture is then condensed into a liquid state and collected. The gas inside the entire pipeline is circulated by the operation of the built-in fan. The condensed gas in the condenser passes through the second pipeline, the gas collection box, each hollow tube, and the moisture-absorbing material in each solar collector tube before entering the base box again and returning to the condenser through the first pipeline. This multiple circulation ensures that the moisture in the moisture-absorbing material is fully condensed and collected, improving the recovery efficiency. The controller is communicatively connected to each fan and valve, enabling automated and precise control of the entire device. The entire device has a simple structure, all components are easy to maintain, and the manufacturing cost is low, making it suitable for large-scale promotion and application.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] The purpose of this invention is to provide an atmospheric water collection device to solve the problems existing in the prior art. It has a simple structure, is easy to maintain, and has low cost.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Example 1

[0026] This embodiment provides an atmospheric water collection device, mainly but not limited to applications in arid areas. As shown in Figure 1, it includes a heat collection mechanism, a condenser 7, an external fan 6, a built-in fan 8, and a controller. The heat collection mechanism includes a base box 1, a gas collection box 2, and multiple solar heat collection tubes 3. The bottom of each solar heat collection tube 3 is sealed, and the upper opening of each solar heat collection tube 3 is connected to the inner cavity of the base box 1. A hollow tube 5 is sleeved inside the solar heat collection tube 3, and a moisture-absorbing material 4 is placed between the solar heat collection tube 3 and the hollow tube 5. The upper opening of the hollow tube 5 is connected to the gas collection box 2 through a three-way connector. The three-way connector has an inlet, a first outlet, and a second outlet 12. The upper opening of the hollow tube 5 is connected to the inlet, the first outlet is connected to the gas collection box 2, and the second outlet 12 is connected to the outside. The first outlet is provided with a... A first valve 11 and a second valve are provided on the second outlet 12; the condenser 7 has an air inlet, an air outlet and at least one water outlet; the air inlet is connected to the base box 1 through the first pipe 9, the air outlet of the external fan 6 is connected to the first pipe 9, and the air inlet of the external fan 6 is connected to the outside (a filter screen can also be provided at the air inlet of the external fan 6 as needed to filter the intake air); a third valve 13 is provided at the air outlet of the external fan 6; a fourth valve 14 is provided at the air inlet of the condenser 7; the air outlet is connected to the gas collection box 2 through the second pipe 10, and the built-in fan 8 is built inside the second pipe 10; the controller is communicatively connected to the external fan 6, the built-in fan 8, each of the first valves 11, each of the second valves, the third valve 13 and the fourth valve 14.

[0027] By employing a method of nighttime moisture absorption and daytime desorption; nighttime moisture absorption: at this time, all first valves 11 and fourth valves 14 are in the closed state. At night, the external fan 6 draws in the air containing moisture from the outside into the base box 1, and the moisture is absorbed sequentially through the moisture-absorbing material 4 from the upper opening of each solar collector tube 3, and then enters the hollow tube 5 from the lower opening. The moisture-absorbing material 4 absorbs and stores the moisture, while the remaining air is discharged from the second outlet 12 of the three-way connector at the upper opening of the hollow tube 5, thus realizing the nighttime moisture absorption action and improving the moisture absorption efficiency; daytime desorption: at this time, all second valves and third valves 13 are in the closed state. During the day, the solar collector tubes 3 are heated by sunlight, thereby evaporating the moisture on the moisture-absorbing material 4. The gas carrying evaporated moisture sequentially enters the condenser 7 through the base box 1 and the first pipe 9. The evaporated moisture is condensed into a liquid state and collected. The gas inside the entire pipe is circulated by the built-in fan 8. The condensed gas in the condenser 7 passes through the second pipe 10, the gas collection box 2, each hollow pipe 5, and the moisture-absorbing material 4 in each solar collector tube 3 before entering the base box 1 again. It then returns to the condenser 7 through the first pipe 9. This multiple circulation fully condenses and collects the moisture in the moisture-absorbing material 4, improving the recovery efficiency. The controller is communicatively connected to each fan and valve, enabling automated and precise control of the entire device. The entire device has a simple structure, all components are easy to maintain, and the manufacturing cost is low, making it suitable for large-scale promotion and application.

[0028] Specifically, the switching between nighttime moisture absorption and daytime desorption can be achieved manually by setting a timer on the controller (such as pre-setting a corresponding time program in the controller so that these devices can be turned on or off according to the set time), or by setting a separate existing photosensor (such as a photoresistor sensor), with the controller communicating with the photosensor and using the photosensor's sensing signal of light intensity to achieve switching control.

[0029] Specifically, the atmospheric water collection device provided in this embodiment makes full use of solar energy, is pollution-free, and compared with traditional devices, it has low energy consumption (no external power supply required), making it suitable for remote and arid areas.

[0030] To ensure efficient moisture absorption at night while effectively controlling the energy consumption of the external fan 6, the following settings can be implemented:

[0031] In the optional scheme of this embodiment, a humidity sensor is preferably provided at the second outlet 12 of the three-way connector, and the humidity sensor is communicatively connected to the controller. The controller can dynamically adjust the operating status of the device based on the humidity data fed back by the humidity sensor. When the ambient air humidity is high, the controller can appropriately increase the speed of the external fan 6 to accelerate air circulation, allowing more humid air to enter the device and come into contact with the moisture-absorbing material 4, thereby improving the moisture absorption efficiency. When the air humidity is low, the controller can reduce the speed of the external fan 6 or even turn off the external fan 6 to reduce unnecessary energy consumption.

[0032] Specifically, a humidity sensor can be installed at the second outlet 12 of a tee connector, or a humidity sensor can be installed at the second outlet 12 of each tee connector. In this case, each humidity sensor is used to sense the moisture content in the gas discharged from the second outlet 12 of the corresponding tee connector, so that the controller controls the corresponding second valve to close.

[0033] To facilitate its relocation, it can also be configured as follows:

[0034] In the optional solutions of this embodiment, a preferred embodiment further includes a base, on which the heat collection mechanism, condenser 7, external fan 6, and controller are all fixedly mounted. A moving mechanism is provided at the lower end of the base, enabling the base to be moved. This allows the device to be flexibly moved to locations with better lighting and higher humidity, based on the climate characteristics of different regions and seasons, as well as factors such as the angle of sunlight, to improve heat and water collection efficiency. The moving mechanism also allows the device to be easily moved to a designated location when maintenance, repair, or component replacement is required, facilitating operation by staff. The base with the moving mechanism allows the water collection device to be used not only in fixed locations but also in temporary locations or scenarios requiring frequent relocation, such as field camps or temporary disaster relief sites. The device can be moved as needed to provide timely water supply to people.

[0035] Specifically, the moving mechanism can be four rollers that are manually propelled; or it can be a device that supports automatic movement, such as one that includes multiple rollers for movement and a drive for rotating each roller, such as a drive motor.

[0036] To facilitate the collection of condensate, the following settings can be implemented:

[0037] In the optional embodiments of this example, as shown in Figure 1, a water collection bottle 15 is further included. The upper opening of the water collection bottle 15 is located below each water outlet, and the water flowing out of each water outlet can flow into the water collection bottle 15. The position design of the water collection bottle 15 ensures that the water flowing out of the condenser 7 outlet can flow directly into the bottle, achieving efficient collection of condensate, reducing water loss during the collection process, and improving water collection efficiency. Gravity is used to automatically allow the water flowing out of each outlet to flow into the water collection bottle 15. The water collection bottle 15 can be transparent or semi-transparent, allowing users to intuitively observe the amount and quality of the collected water.

[0038] The following are the settings instructions for condenser 7:

[0039] In a preferred embodiment, the condenser 7 includes a bottom integrated box, a top integrated box, multiple first condenser tubes, and multiple second condenser tubes. The bottom integrated box is located below the top integrated box and has a first cavity and a second cavity inside. The first cavity is connected to the inner cavity of the top integrated box through each of the first condenser tubes, and the second cavity is connected to the inner cavity of the top integrated box through each of the second condenser tubes. The bottom integrated box has an air inlet and an air outlet, with the air inlet connected to the first cavity and the air outlet connected to the second cavity. The bottom integrated box has two water outlets, one of which is connected to the first cavity and the other is connected to the second cavity. The bottom integrated box has a first cavity and a second cavity, which are connected to the inner cavity of the top integrated box through the first and second condenser tubes, respectively. This makes the gas flow path in the condenser 7 more complex, increases the contact area and contact time between the gas and the condenser tubes, and allows the gas to flow in a meandering manner between the two cavities, enabling more thorough heat exchange with the condenser tubes, thereby improving condensation efficiency and causing more water vapor to condense into liquid water.

[0040] In the optional embodiments of this example, it is more preferred that the inner diameter of the first condenser tube is larger than that of the second condenser tube. The larger inner diameter of the first condenser tube allows for a longer residence time of the gas within the tube, enabling full utilization of the internal space for heat exchange. This allows some of the water vapor in the gas to initially condense into liquid water within the first condenser tube. The remaining uncondensed water vapor enters the second condenser tube, where the smaller inner diameter increases the amount of gas per unit volume, increasing the contact opportunities between the water vapor and the inner wall of the condenser tube. Furthermore, the increased gas flow velocity further promotes the condensation of the water vapor. This combination design of condenser tubes with different inner diameters allows for the staged and layered condensation of water vapor in the gas, thereby improving overall condensation efficiency and increasing water collection capacity.

[0041] The following are the relevant settings instructions for the solar collector tube 3:

[0042] In the optional solutions of this embodiment, a preferred embodiment is shown in Figure 1, where the bottom of the hollow tube 5 has a first distance from the inner bottom of the solar collector tube 3. The existence of the first distance creates a certain space between the inner bottom of the solar collector tube 3 and the bottom of the hollow tube 5, allowing air to circulate freely within this space, thereby achieving a better gas flow effect.

[0043] In the optional solutions of this embodiment, as shown in Figure 1, the first spacing is preferably 5cm to 10cm.

[0044] In the optional solutions of this embodiment, as shown in FIG1, the bottom of the moisture-absorbing material 4 has a second distance from the inner bottom of the solar collector tube 3.

[0045] Specifically, the second spacing is the same as the first spacing.

[0046] To improve energy efficiency, the following settings can also be implemented:

[0047] In the optional solutions of this embodiment, a preferred option is to further include an energy supply mechanism, which includes a solar panel and a battery. The solar panel and the battery are electrically connected, and the battery is electrically connected to the controller, the external fan 6, the internal fan 8, each of the first valves 11, each of the second valves, the third valve 13, and the fourth valve 14. This energy supply method enables the atmospheric water collection device to have a relatively independent energy supply system, without relying on an external power grid. Even in remote areas or places where the power grid is not covered, the device can operate normally by relying on solar energy and the battery, enhancing the device's autonomy and adaptability, and expanding its application range. Utilizing solar energy, a free energy resource, can significantly reduce the operating costs of the device in the long run. Compared with using mains electricity or other traditional energy sources, there is no need to pay for electricity or fuel, reducing costs in energy procurement and transportation, resulting in better economic benefits.

[0048] Specifically, in addition to the electrical equipment mentioned above, the battery can also supply power to other components on the device that require electrical energy, including but not limited to humidity sensors.

[0049] Regarding other related settings:

[0050] Specifically, the controller can also be configured to support wireless remote data transmission and remote control, enabling control of related equipment and reception and setting of data through ground wireless receiving equipment.

[0051] Specifically, since the device is installed outdoors, a necessary protective cover can be installed on the outside of the controller to reduce damage from rain and other sources.

[0052] Specifically, a water level sensor can also be installed in the water collection bottle 15. The water level sensor is connected to the controller. When the water in the water collection bottle 15 reaches the maximum water level, the controller controls the entire device to stop condensing the water, or the controller is connected to an alarm to provide an alarm prompt.

[0053] Specifically, the solar collector tube 3 and the moisture-absorbing material 4 are existing components, and will not be described in detail here.

[0054] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
