Description

Technical Field

[0001] This utility model relates to the field of air technology, and in particular to an adsorption-type air-water intake window awning. Background Technology

[0002] With the global water shortage becoming increasingly severe, the search for and development of new water extraction technologies has become a key research focus in the field of water resources. Currently, air-based water extraction technologies are mainly divided into two categories: direct condensation and biomimetic fog collection.

[0003] Direct condensation lowers the air temperature below the dew point, causing water vapor in the air to condense into liquid water. However, this method requires a large amount of electrical energy to provide the refrigeration power, and it is difficult to effectively extract water in environments with dew point temperatures below 4.5°C, thus limiting its application.

[0004] Bionic fog collection methods use large-area water-collecting materials to gather water vapor from the air without requiring additional energy. However, this method yields relatively small amounts of water and is highly dependent on environmental conditions, such as air humidity and wind speed, which can affect its effectiveness. In areas with water scarcity and harsh environmental conditions, the practicality of bionic fog collection methods is also limited.

[0005] In recent years, adsorption-based air-to-water extraction technology has gradually emerged. This technology utilizes the hygroscopic properties of adsorbents to extract water from the air through adsorption and desorption processes. Adsorption-based air-to-water extraction technology has advantages such as high water extraction efficiency and low requirements for environmental conditions. However, current adsorption-based air-to-water extraction devices used in laboratories still have some shortcomings.

[0006] A water collection device with Chinese patent number CN2021105000277 uses an exhaust module, a condensation module, and an intake enhancement component installed between them to collect water from the air. The principle is simple, but the condensation module uses semiconductor refrigeration, which consumes electrical energy. Furthermore, the water collection is unstable due to the influence of the partial pressure of water vapor in the air, resulting in poor practicality. A water collection device with Chinese patent number CN202311061864X uses microfluidic condensation technology to gradually reduce the water vapor flow area and increase the mass flow rate to collect water from the air. The principle is simple, but the water collection efficiency is low in areas where the dew point temperature is not low enough. Additionally, the water collection is unstable due to the influence of the partial pressure of water vapor in the air, failing to meet human water needs and resulting in poor practicality.

[0007] These devices are often too simple in structure, have great limitations in water intake environment conditions, and are only suitable for testing the water intake performance of small amounts of adsorbent materials. Therefore, their water intake effect and practicality in real-world applications are greatly limited.

[0008] In addition, the water collection device with Chinese patent number CN2021105361523 utilizes an adsorption bed and a semiconductor condenser component, and simultaneously uses solar heating to raise the dew point temperature within the device. While the principle is simple, it still requires an electrical supply, and in some cases, its operating conditions cannot be met, resulting in poor practicality. This device uses microfluidic condensation technology to collect water from the air, improving water collection efficiency by reducing the water vapor flow area and increasing the mass flow rate. However, in areas where the dew point temperature is not low enough, the water collection efficiency is not high, and it is also affected by the partial pressure of water vapor in the air, leading to unstable water collection. Other water collection devices, such as the one disclosed in patent number CN2021105361523, combine an adsorption bed and a semiconductor condenser component, and utilize solar energy for heating to raise the dew point temperature within the device. While achieving green energy saving to some extent, it still requires an electrical supply to drive the semiconductor condenser component. In areas lacking a stable power supply, its practicality is also limited.

[0009] Existing adsorption-type air-to-water extraction devices still have many shortcomings in terms of water extraction efficiency, practicality, and environmental adaptability. Therefore, there is an urgent need in this field to develop an adsorption-type air-to-water extraction device with a more rational structure, higher water extraction efficiency, and greater practicality. Utility Model Content

[0012] An adsorption-type air-water intake window awning includes:

[0013] A window awning system includes a window awning housing, a mounting cavity provided on the window awning housing, and a cover plate provided on the window awning housing, the cover plate being capable of opening and closing the mounting cavity.

[0014] The water intake system includes an adsorption bed, which is installed in the mounting cavity or on the cover plate of the window awning shell.

The condensed liquid water will flow into the water intake container through the water outlet pipe.

[0015] Furthermore, the water intake system also includes a collection device for collecting and discharging the liquid water desorbed from the adsorption bed.

[0016] Furthermore, a water inlet pipe is provided at the lowest point of the collecting device, and the water inlet pipe is connected to the water outlet pipe.

[0017] Furthermore, the connection end between the cover plate and the support device is located near the water inlet pipe, and the cover plate is hinged to rotate relative to the window sill shell under the action of the support device.

[0018] Furthermore, the adsorption bed is arranged in an inclined downward direction within the installation cavity from the end furthest from the water inlet pipe to the end closest to the water inlet pipe.

[0019] Furthermore, support feet are provided on the two side plates and / or bottom plate of the window sill shell to support and fix the adsorption bed in the installation cavity, and are designed to slope downward from the end away from the water inlet pipe to the end closer to the water inlet pipe.

[0020] Furthermore, a limiting module is provided on at least one support foot, the limiting module being used to limit and fix the position of the adsorption bed.

[0021] Furthermore, the cover plate is designed below the mounting cavity, and the cover plate opens or closes the opening below the mounting cavity under the action of the support device.

[0022] Furthermore, the cover plate is arranged horizontally or inclined downwards from the end away from the water inlet pipe to the end closer to the water inlet pipe.

[0023] Furthermore, the window sill shell includes a water storage section and a water intake section. The mounting cavity is located in the water storage section, and the water intake section is located near the rear end of the water storage section near the water inlet pipe and extends downward. A liquid storage cavity is provided in the water intake section, and the liquid storage cavity is connected to the mounting cavity through a water outlet pipe.

[0024] Compared with existing technologies, the adsorption-type air-water intake window awning of this utility model has the following advantages:

[0025] (1) The adsorption-type air-water intake window awning of this utility model utilizes an idle window awning and combines it with a water intake system.

Detailed Implementation

[0037] To make the technical means and objectives and effects of this utility model easier to understand, the embodiments of this utility model will be described in detail below with reference to specific figures.

[0041] Adsorption-based air-to-water collection primarily involves two states: adsorption and desorption. Since thermosensitive photothermal pollen can directly utilize sunlight for desorption, when exposed to sunlight, it effectively absorbs energy and converts it into heat. This heat is then used to raise the temperature of the pollen material, promoting the desorption of water vapor adsorbed on its surface or inside. When using thermosensitive photothermal pollen for adsorption-based air-to-water collection, the pollen material has a strong adsorption capacity at lower temperatures, capable of adsorbing and enriching water vapor in the air. However, when sunlight irradiates and heats the pollen material, its temperature gradually increases, leading to a weakening of the adsorption capacity, thus causing the adsorbed water vapor to desorb and be released. Simultaneously, the applicant noted that many buildings have sunshade eaves, and the solar radiation blocked by these eaves can be utilized in the air-to-water collection system. Therefore, this applicant innovatively proposes an adsorption-based air-to-water eave that combines eaves shading technology with adsorption-based air-to-water collection technology.

[0042] like Figures 1-4 As shown, this application discloses an adsorption-type air-water intake window awning, comprising:

[0043] The window awning system 100 includes a window awning housing 7, a mounting cavity 701 provided on the window awning housing 7, and a cover plate 3 provided on the window awning housing 7, the cover plate 3 being capable of opening and closing the mounting cavity 701.

[0044] A water intake system 200 is installed in the mounting cavity 701 of the window awning housing 7 and / or on the cover plate 3;

[0045] The water intake system 200 includes an adsorption bed 1 and an outlet pipe 9. The adsorption bed 1 can enrich water vapor from the air and desorb the adsorbed water vapor after the temperature rises. The condensed liquid water will flow into the water intake container through the outlet pipe 9.

[0046] In the example of this application, water is collected using an unused window sill. A window sill housing 7 containing an installation cavity 701 is installed at the window sill. Then, a water collection system 200 containing an adsorption bed 1 and a water outlet pipe 9 is installed inside the installation cavity 701 of the window sill housing 7 and / or on the cover plate 3. By setting the installation cavity 701 in the window sill housing 7 or an extension structure of the window sill housing 7, it serves as the housing for the adsorption bed 1. The adsorption bed 1 is coated with an adsorbent material, which can enrich water vapor from the air and reduce the adsorption capacity when the temperature rises, thus desorbing the adsorbed water vapor. The adsorbent material can be selected from materials and structures known in the prior art, such as silica gel, molecular sieve, activated carbon, or polymer adsorbent materials such as polyamide and polyester. The adsorbent material has certain reusability. When the cover plate 3 is closed on the mounting cavity 701, the water intake system 200 is installed inside the mounting cavity 701 of the window sill housing 7. During use, a complete adsorption water intake cycle includes an adsorption stage and a regeneration stage. During the adsorption stage, such as at night or in humid weather, the mounting cavity 701 of the window sill housing 7 is opened by controlling the movement or rotation of the cover plate 3. Water vapor or humid air enters and contacts the adsorption bed 1, where it is adsorbed until adsorption saturation or a preset time is reached. Then, the cover plate 3 is closed, and the mounting cavity 701 of the window sill housing 7 is closed, entering the regeneration stage of the adsorption water intake cycle, such as during the day. The adsorption bed 1 is no longer in contact with the outside air. The temperature of the space containing the adsorption bed 1 is increased by heating the eaves shell 7 of the water intake system 200 through solar radiation. This reduces the adsorption capacity of the adsorption material on the adsorption bed 1, causing the adsorbed water vapor to desorb. The desorbed water vapor then contacts the shell of the space containing the adsorption bed 1. Preferably, the shell is the eaves shell 7, but it can also be an adsorption bed shell with an opening covering the outside of the adsorption bed 1. This creates an adsorption stage where the adsorption bed efficiently adsorbs water vapor from the air to saturation at night or during periods of high humidity. During the day, sunlight heats the eaves shell and its interior, raising the temperature of the adsorption material and reducing its adsorption capacity, thus releasing water vapor in a regeneration stage. Because the water vapor partial pressure inside the space containing the adsorption bed 1 is high, the condensation temperature of the water vapor is lower. When the water vapor comes into contact with the eaves shell 7 or the adsorption bed shell, which is below the condensation temperature, it condenses into water droplets. These condensed water droplets slowly flow down from the shell, collect, form a water stream, and eventually flow into the water intake container through the outlet pipe 9. After the regeneration phase is completed, open the cover plate 3 again, remove the water container from the installation cavity 701, and start a new cycle.

[0047] The adsorption-type air-source water intake window awning disclosed in this application utilizes an idle window awning and integrates it with a water intake system 200. By controlling the opening and closing of the window awning housing 7, the adsorption and regeneration times of the water intake system 200 are separated, optimizing water intake efficiency and achieving zero-energy, full-lifecycle water intake. This device retains the original function of the window awning while adding new value, making it particularly suitable for water-scarce environments and effectively alleviating or even solving water shortage problems in some areas. Its energy-free saturated condensation design ensures water quality and extends the system's lifespan, achieving efficient, stable, and continuous water intake.

[0048] As a preferred example of this application, the water intake system 200 further includes a collection device 5, which is used to collect and discharge the liquid water desorbed from the adsorption bed. In the example of this application, the collection device 5 is disposed below the adsorption bed 1, and the collection device 5 is preferably a flat plate that slopes from both sides towards the middle, with a rectangular flat plate in the middle connecting the two flat plates. The liquid water source is tightly connected to the bottom plate of the adsorption bed shell or the window sill shell 7 on the flat plate of the collection device 5, thereby realizing that the water vapor in the regeneration stage condenses into water droplets due to the high partial pressure inside the window sill shell, and flows down along the inclined collection device 5, and finally flows into the water intake container installed by the user through the designed water path, completing the entire water intake process without the need for electric power, reducing energy consumption, and avoiding the problem of not being able to extract water due to insufficient power.

[0049] As a preferred example of this application, a water inlet pipe 4 is provided at the lowest point of the collecting device 5, and the water inlet pipe 4 is connected to the water outlet pipe 9. In this example, the flat plate near the middle of the collecting device 5 is tightly connected to the bottom plate of the outer shell of the space where the water intake system 200 is located. The main function of the collecting device 5 is to collect the liquid water desorbed from the adsorption bed to the water inlet pipe 4, thereby ensuring that the desorbed liquid water can be collected quickly and completely, avoiding water loss and waste. The water inlet pipe 4 is a small hole on the bottom plate of the outer shell, which has a certain downward tilt angle, accelerating the water flow guidance process and better guiding the collected water to the water outlet pipe 9. As a specific example of this application, the water outlet pipe 9 is a short section of PVC pipe, which is not only easy to install but also durable. Users can easily connect it to the water collection container with a flexible hose, greatly improving the user experience and convenience.

[0050] This improved design greatly enhances the efficiency of liquid water collection and the ease of operation for users, enabling the effective recycling and utilization of water resources.

[0051] As a preferred example of this application, the cover plate 3 is designed below the mounting cavity 701, and the cover plate 3 opens or closes the opening below the mounting cavity 701 under the action of the support device 6. In this example, the entire water intake system 200 is designed inside the mounting cavity 701, and the cover plate 3 only serves to open or close the mounting cavity 701 under the action of the support device 6. The support device 6 is preferably a hydraulic rod. By symmetrically designing two hydraulic rods at opposite ends along the length of the cover plate 3, reliable closure of the cover plate 3 relative to the mounting cavity 701 on the window sill shell 7 can be achieved. In this example, the adsorption bed 1 of the water intake system 200 can also be designed on the cover plate 3, and move integrally to the outside of the mounting cavity 701 when the cover plate 3 is opened to perform the adsorption stage. This setup effectively protects the water intake system 200 and its adsorption bed 1, while also facilitating convenient operation. During the regeneration phase, the cover plate 3, under the support device 6, tightly seals the installation cavity 701, effectively preventing external dust and impurities from entering. Simultaneously, it allows the installation space of the adsorption bed 1 inside the window sill shell 7 to rapidly heat up under sunlight, enabling rapid and reliable desorption of adsorbed water vapor and protecting the cleanliness and normal operation of the water intake system 200. When the adsorption phase is required, the cover plate 3 can be easily opened, exposing the adsorption bed 1 of the water intake system 200. This allows water vapor or high-humidity air to enter the installation cavity 701, contact the adsorption bed 1, and be adsorbed, ensuring reliable adsorption operation.

[0052] As a preferred example of this application, the connection end between the cover plate 3 and the support device 6 is located near the water inlet pipe 4, and the cover plate 3 is hinged to rotate relative to the window sill shell 7 under the action of the support device 6. This arrangement enables reliable switching between adsorption and regeneration operations of the adsorption-type air-water intake window sill described in this application, making operation more flexible and convenient, and greatly improving the user experience.

[0053] As a preferred example of this application, the adsorption bed 1 is arranged in an inclined downward direction within the mounting cavity 701 from the end furthest from the water inlet pipe 4 to the end closest to the water inlet pipe 4. In the example of this application, when the window sill shell 7 is used as the adsorption bed shell, the window sill shell 7 includes at least a top plate, a rear plate, a front plate, and two side plates, forming an opening of the mounting cavity 701 at the lower end, and the opening can be covered and closed or opened by the cover plate 3. Alternatively, the window sill shell 7 also includes at least one bottom plate, and the opening of the mounting cavity 701 is an opening structure provided on the bottom plate. The water inlet pipe 4 is provided at the rear end of the window sill shell 7. By providing support feet 2 on the two side plates and / or the bottom plate of the window sill shell 7, the adsorption bed 1 is supported and fixed in the mounting cavity 701 and designed to be inclined downward from front to back. This setup allows the adsorption bed 1 to more effectively guide the liquid water to the water inlet pipe 4 during the adsorption process, thereby improving the water collection efficiency. At the same time, the structure of the window sill shell 7 and the support of the support feet 2 not only ensure the stable installation of the adsorption bed 1, but also make the structure of the entire water intake system more compact and reasonable.

[0054] In the example of this application, the support feet 2 are four fixed supports installed at a certain angle inside the window sill shell 7. The two fixed supports at the higher position have parallelogram-shaped sides, which can well support the weight of the adsorption bed. The two fixed supports at the lower position are also provided with limit modules 10 on their upper surfaces. The limit modules 10 are rectangular wooden blocks fixed above the support feet 2. The limit modules 10 can effectively fix the position of the adsorption bed 1 in the designed position, preventing the adsorption bed 1 from shifting and affecting the adsorption performance.

[0055] This design simplifies the structural design, enhances the support strength, and improves the space utilization. The setting of the limiting module 10 effectively solves the displacement problem that may occur in the adsorption bed 1 during operation, ensuring the stability and adsorption efficiency of the adsorption bed 1.

[0056] In the example of this application, the cover plate 3 is arranged horizontally or inclined downwards from the end away from the water inlet pipe 4 to the end closer to the water inlet pipe 4. Preferably, the cover plate 3 is designed to be inclined downwards from the end away from the water inlet pipe 4 to the end closer to the water inlet pipe 4. This arrangement further optimizes the performance of the adsorption-type air intake window awning described in this application. The inclined design of the cover plate 3 increases the area of ​​the opening of the mounting cavity 701, improving the efficiency of water vapor-rich air entering the mounting cavity 701 and adsorbing with the adsorption bed 1 under adsorption conditions. At the same time, it also allows the water collected on the cover plate 3 to flow smoothly to the water inlet pipe 4 under regeneration conditions, improving the liquid water collection efficiency and reducing the need for system maintenance.

[0057] In the example of this application, a liquid storage chamber 11 is provided at the rear end of the window sill housing 7, and the liquid storage chamber 11 is connected to the mounting cavity 701 through a water outlet pipe 9. This design allows the liquid collected after regeneration to flow smoothly into the liquid storage chamber 11 for temporary storage during the adsorption and regeneration cycle of the water intake system 200. The liquid storage chamber 11, as an independent storage space, can effectively accommodate and accumulate this liquid until a certain amount is reached or after multiple adsorption and regeneration cycles, at which point it can be removed by the user without frequent water extraction operations, greatly improving the user experience.

[0058] In the example of this application, the window awning housing 7 includes a water storage section 71 and a water intake section 72. The mounting cavity 701 is disposed in the water storage section 71, and the water intake section 72 is disposed in the water storage section 71 near the rear end of the water inlet pipe 4 and extends downward. The liquid storage cavity 11 is disposed in the water intake section 72, and a base 8 is disposed at the lower end of the water intake section 72. In the example of this application, the window awning housing 7 can be provided with only the water storage section 71, and the cover plate 3 is disposed at the bottom of the window awning housing 7. Alternatively, a structure including the water intake section 72 and the water storage section 71 can be provided. The water intake section 72 is generally a flat plate design containing a cavity (liquid storage cavity 11), and the water intake section 72 is designed to protrude to one side relative to the water storage section 71. In this case, the water intake section 72 can also be designed to be horizontal with respect to the ground, and the water intake section 72 is disposed above the water storage section 71. The adsorption-type air intake window awning is fixedly connected to the window base plate through the base 8.

[0059] This design, through the ingenious combination of the water storage section 71 and the water intake section 72, enables the entire system to efficiently perform adsorption, regeneration, and liquid storage. The raised or horizontal design of the water intake section 72, along with the fixed connection function of the base 8, makes the water intake system more adaptable to different installation environments and usage requirements. This significantly improves the structural compactness and stability of the adsorption-type air intake window awning described in this application, and also significantly enhances its practicality and convenience.

[0060] Based on the fact that many buildings have numerous unused sunshade eaves, the applicant innovatively combines the sunshade technology of these eaves with adsorption-type air-water extraction technology to create adsorption-type air-water extraction eaves. The overall principle is as follows: Figure 5As shown, adsorption-type air water collection mainly involves two states, corresponding to the adsorption state and the desorption state. The adsorption state requires contact with the atmosphere, while the desorption state requires the formation of a closed chamber (installation chamber 701). Combining existing adsorbents that can directly absorb solar radiation to generate heat and desorb the absorbed water, and whose black color allows for effective solar radiation absorption and shading, an aluminum sheet coated with thermosensitive photothermal pollen is placed directly on a perforated partition plate (forming an adsorption bed 1) in the air-water collection window sill. This is then tilted and fixed above the window as a window sill to maximize the area exposed to sunlight. The area of ​​the adsorbent aluminum sheet needs to be slightly smaller than the area of ​​the perforated plate to allow air to contact the adsorbent on the aluminum sheet. A small chamber (the window sill shell 7 containing the water storage section 71) is formed above, in front of, to the left of, and to the right of the perforated partition plate. A partition plate (cover plate 3) that flips using a telescopic rod is installed below the perforated partition plate containing the adsorbent aluminum sheet to control the opening and closing of the chamber. The telescopic pole is powered by solar energy absorbed by thin-film batteries.

[0061] The two processes of adsorption and desorption on the window sill are as follows: Figure 6 As shown, at night, the lower partition opens, allowing air to pass through the perforated placement plate and reach the top of the adsorbent aluminum sheet, where it comes into contact with the adsorbent. The adsorbent absorbs water vapor from the air. During the day, the lower partition closes, sealing the adsorbent aluminum sheet into a cavity. The adsorbent on the aluminum sheet absorbs solar radiation, heats up, and desorbs the adsorbed water vapor. The humidity inside the cavity continuously rises, and the hot, humid air inside the cavity condenses into droplets upon contact with the cooler surrounding partitions. By tilting the upper and lower partitions of the aluminum sheet placement plate at a certain angle, a larger shading area is achieved. Furthermore, during desorption, water vapor condenses into droplets upon contact with the upper partition and rolls down the slope to the lower partition. Since the lower partition is also closed and slopes upwards, the droplets also roll down to the water collection tank and flow into the room.

[0062] The applicant placed an adsorbent aluminum sheet made of thermosensitive photothermal pollen into an adsorption-type air-water-collecting window awning model and conducted a desorption experiment under sunlight. Before the experiment, the thermosensitive photothermal pollen aluminum sheet was placed in a constant temperature and humidity chamber at 20℃ and 80% RH for 2 hours for adsorption. Sunlight was absorbed by the black adsorbent through the transparent partition on the adsorbent aluminum sheet, forming a shadow below, indicating that the adsorbent aluminum sheet can achieve a shading effect. Under solar radiation at 13:00, the adsorbent aluminum sheet in the window awning model rapidly heated up, desorbing the previously adsorbed moisture. After only 15 minutes, a layer of water mist formed on the upper transparent partition. As desorption proceeded, the water droplets on the upper partition gradually gathered and grew larger. Because the upper partition was hydrophobic and had a certain slope, the droplets flowed along the upper partition to the front vertical plate and then to the lower plate. The lower plate also had a certain slope, so the liquid water flowed to the lower end of the chamber near the wall model plate, achieving liquid water collection. This single desorption experiment collected 4.4 ml of liquid water, used an aluminum sheet with an area of ​​10 cm * 20 cm, coated with 10.6 g of thermosensitive photothermal pollen, and had an average coating weight of 530 g / m². 2 The average water consumption per unit area is 220g / m². 2 .

[0063] The adsorption-type air-to-water sampling window awning disclosed in this application has at least the following beneficial effects compared to existing adsorption-type air-to-water sampling experimental devices:

[0064] First, this application utilizes highly efficient and renewable adsorbent materials, significantly improving moisture absorption performance and desorption rate. During the adsorption stage, the material efficiently absorbs water vapor molecules from the air; during the regeneration stage, through solar irradiation, the material rapidly completes the desorption process, accelerating heat and moisture transfer rates, thereby improving the overall water extraction efficiency of the system.

[0065] Second, this application utilizes solar energy as a heat source, achieving a green and energy-saving water intake method. The system requires no external electrical input, achieving water vapor desorption and condensation through solar heating. This form of saturated condensation without electricity not only reduces energy consumption but also minimizes environmental pollution, meeting the requirements of sustainable development.

[0066] Third, this application also ensures water quality and extends the service life of the water system. Because the system is isolated from the external environment during desorption, the entry of external contaminants is effectively prevented. Furthermore, lower condensation temperatures are sufficient to meet condensation requirements, further reducing energy consumption and costs.

[0067] Fourth: The adsorption-type air intake window of this application has the advantages of easy installation, disassembly, and replacement. The adsorption material used on the surface of the adsorption bed has a certain degree of reusability, reducing the cost of use. At the same time, the water outlet pipe and water collection container are set at the rear of the adsorption bed shell, which facilitates the storage and use of the collected water and avoids the water from being contaminated. These designs make the entire system more practical, convenient, and efficient.

[0068] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
