Description

Technical Field

[0001] This utility model relates to the technical field of solar-powered air-to-water conversion, and in particular to a portable solar-powered air-to-water generator. Background Technology

[0002] In remote environments such as tourism, outdoor adventure, fieldwork, emergency rescue, and military operations, the need for continuous access to clean drinking water is crucial. The traditional solution is to carry large quantities of pre-packaged drinking water, which is not only inefficient but also inadequate for meeting long-term or sudden water demands. Therefore, carrying an air-to-water generator (ATM) has become a highly efficient alternative. ATMs can extract moisture directly from the air and convert it into drinking-grade water in water-scarce environments. However, in practical applications, this device faces two major challenges.

[0003] First, the energy supply issue is particularly prominent. In outdoor environments, grid access is often unavailable, forcing air-to-water generators to rely on independent power sources. Solar energy, as a renewable resource, is the optimal solution to this problem. However, currently available air-to-water generators, especially those with practical water production capacity, are often bulky, heavy, and complex in structure, failing to meet the demands of outdoor activities for portability, ease of use, and rapid deployment.

[0004] Secondly, with the increasing demand for portability, the design of equipment faces more stringent constraints. Existing air-to-water generators, in order to ensure sufficient water production, often incorporate complex and space-consuming cooling systems and water separation devices, resulting in bulky and difficult-to-move equipment. Therefore, developing a portable solar-powered air-to-water generator that efficiently utilizes solar energy while possessing a compact structure, lightweight design, and ease of carrying and operation is of great significance for users working outdoors, hence this project.

[0012] Furthermore, the water storage tank integrates a UVLED sterilization component, and a water pump is installed on the water pipe between the water filtration component and the water outlet. The water pump is connected to a control board and an energy storage battery.

[0013] Furthermore, the foldable solar charging panel is fixed together with the backpack, and the solar charging panel includes at least one set of solar panels, which are fixed to the top or outside of the backpack.

[0014] Furthermore, the foldable solar charging panel is separate from the backpack, and the solar charging panel is connected to the energy storage battery via a data cable.

[0015] Furthermore, the outer periphery of the backpack is equipped with a temperature and humidity sensor connected to the control board, the energy storage battery has a data acquisition module for collecting charging current and energy storage battery power data, and the backpack is also equipped with an operation panel connected to the control board.

[0026] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0027] In the description of this utility model, the backpack has an inner surface, an outer surface, two side surfaces, a top surface, and a bottom surface. The inner surface is the side that comes into contact with the user, the other side is the outer surface, and the left and right sides are the side surfaces. This is only for the convenience of describing this utility model and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0028] like Figures 1 to 7 As shown, this utility model discloses a portable solar-powered air-to-water generator, including: a backpack 1, a foldable solar charging panel 2, an energy storage battery 3, a water-making component 4, a water storage tank 5, a water filtration component 6, and a control board 7. The side of the backpack 1 is provided with an air filter 11 and a water outlet 12 connecting the inside and outside of the backpack 1. The water-making component 4, the water storage tank 5, and the water filtration component 6 are all located inside the backpack 1. The inlet of the water-making component 4 is connected to the air filter 11, and the outlet of the water-making component 4 is connected to the water storage tank 5. The water outlet 12 of the water storage tank 5 is connected to the inlet of the water filtration component 6. The water filtration component 6 is connected to the water outlet (12) of the backpack (1) through a water pipe 61. The control board 7 is connected to the energy storage battery 3. The water-making component 4 and the water filtration component 6 are respectively connected to the control board 7. The energy storage battery 3 is connected to the foldable solar charging panel 2. The control board 7 is connected to the operation panel 71.

[0029] This invention utilizes a backpack 1 to house a water-making component 4, an energy storage battery 3, and a foldable solar charging panel 2. The overall structure is compact, allowing the user to easily carry the backpack 1 on their back. The foldable solar charging panel 2 powers the energy storage battery 3, and its foldable design efficiently collects solar energy while being convenient for storage and transport. The solar charging panel 2 converts collected solar energy into electrical energy to charge the energy storage battery 3, thus solving the energy supply problem. The water-making component 4 condenses moisture in the air into water droplets, which are collected and stored in a water tank 5. After filtration by a water filtration component 6, the water can be used directly as drinking water. In use, simply unfold the foldable solar charging panel 2, place it in sunlight, and connect it to the energy storage battery 3 to power it. The operation panel 71 connected to the control board 7 allows for air-to-water production and water output control.

[0030] like Figure 2 As shown, the water production component 4 is a tunnel-type evaporator-condenser assembly 41, which includes a fan 411, an evaporator 412, a condenser 413, and a compressor 414. The air inlet of the fan 411 is connected to the air filter 11, and the air outlet of the fan 411 is connected to the inlet of the evaporator 412. The exhaust port of the compressor 414 is connected to the inlet of the condenser 413 through a pipe fitting. The outlet of the condenser 413 is connected to the inlet of the throttling device through a pipe fitting. The outlet of the throttling device is connected to the inlet of the evaporator 412, and the outlet of the evaporator 412 is connected to the suction port of the compressor 414, thereby realizing the circulation and recovery of refrigerant and forming a complete refrigeration cycle. The water storage tank 5 is connected to the bottom of the evaporator 412.

[0031] The throttling device is a capillary tube or an expansion valve. The refrigerant, liquefied by the condenser 413, is in a high-pressure liquid state. When this high-pressure liquid refrigerant passes through the throttling device, the device restricts its flow, causing a sharp drop in pressure and temperature, transforming it into a low-pressure, low-temperature gas-liquid mixture. This low-pressure, low-temperature refrigerant, upon entering the evaporator 412, more easily absorbs heat from the surrounding environment and evaporates into a gaseous state, thus cooling the evaporator 412 and creating low-temperature conditions for air condensation and water separation. This invention is a small-scale refrigeration system. Considering the miniaturization and portability of the equipment, a capillary tube is preferred as the energy-saving device. The capillary tube has a simple structure and small size, perfectly suited to the compact design of a small air-to-water generator, ensuring efficient operation of the refrigeration cycle.

[0032] The bottom of the evaporator 412 is connected to a water collector, and the outlet of the water collector is connected to the water storage tank 5 through a pipeline. The fan 411 can be a booster axial flow fan, and the compressor 414 is a small DC-powered compressor 414.

[0033] The water production principle of the tunnel-type evaporation-condensation unit 41 is as follows:

[0034] Ambient air first passes through an air filter to remove dust, particulate matter, and other impurities, resulting in purified air. This step ensures the cleanliness of the water produced subsequently. Then, under the action of the booster axial flow fan 411, the purified air is drawn into the pipes of the tunnel-type evaporator-condenser assembly 41. The air flows through the evaporator 412, at which point the compressor 414 begins operation. The compressor 414 is a small DC-powered compressor suitable for operation in environments without a power grid. The compressor 414 compresses the refrigerant into a high-temperature, high-pressure gas, which is then delivered to the condenser 413. The refrigerant liquefies and releases heat in the condenser 413. Subsequently, the liquid refrigerant passes through a throttling device to reduce its pressure before entering the evaporator 412, where it evaporates and absorbs heat, thus lowering the temperature of the evaporator 412. When air flows through the evaporator 412, which has a lower temperature, the moisture in the air condenses upon cooling, forming liquid water droplets. These droplets flow along the surface of the evaporator 412 and eventually collect in the water collector at the bottom of the evaporator 412, before flowing into the water storage tank 5 for storage.

[0035] The air that has completed condensation is not directly discharged, but continues to be blown towards the condenser 413 by the fan 411. At this time, the refrigerant is releasing heat in the condenser 413. As the air flows through the condenser 413, it absorbs the heat released by the condenser 413, thus dissipating heat from the condenser 413. This design makes full use of airflow, using air energy that might otherwise be wasted for heat dissipation in the condenser 413, improving the energy efficiency of the entire system and making the water production process more energy-efficient.

[0036] like Figure 5 As shown, the water-making component 4 can also be a semiconductor cooling component 42. The semiconductor cooling component 42 includes a semiconductor cooling chip 421, a cold-end air condenser 422, a hot-end heat sink 423, and a fan 424. One end of the semiconductor cooling chip 421 is the cooling end, and the other end is the heat dissipation end. The cold-end air condenser 422 is in close contact with the cooling end surface of the semiconductor cooling chip 421, and the hot-end heat sink 423 is in close contact with the heat dissipation end surface of the semiconductor cooling chip 421. The fan 424 is installed on the side of the backpack 1 opposite to the air filter 11. Both the cold-end air condenser 422 and the hot-end heat sink 423 adopt a finned structure to improve heat exchange efficiency.

[0037] The cold end of the thermoelectric cooler 421 lowers the temperature of the cold-end air condenser 422; the hot end of the thermoelectric cooler 421 dissipates heat through the hot-end heat sink 423; under the action of the fan 424, the ambient air is purified by the air filter 11 and then cooled by the cold-end air condenser 422, and the temperature is lower than the dew point, and the moisture in the air condenses into liquid water; the cold air continues to pass over the thermoelectric cooler 421 and flows to the hot-end heat sink 423, using the residual coolness of the air for heat dissipation.

[0038] Preferably, the water storage tank 5 can integrate a UVLED sterilization component, and a water pump 62 is installed on the water pipe 61 between the water filter component 6 and the water outlet. The water pump 62 is connected to the control board 7 and the energy storage battery 3. Specifically, a UVLED sterilization component can be installed inside or on the top of the water storage tank 5. The UVLED sterilization component contains multiple UVLED lamp beads, and the ultraviolet wavelength emitted is concentrated in the range of 200-280nm. This wavelength of ultraviolet light can destroy the DNA or RNA structure of bacteria, viruses and other microorganisms, causing them to lose their ability to reproduce, thereby achieving the purpose of sterilization and disinfection. By setting a UVLED sterilization component in the water storage tank 5, the growth of bacteria in the water storage tank 5 can be effectively inhibited, ensuring the hygiene and safety of the produced water. Moreover, the UVLED module has low power consumption and long life, which is suitable for the energy-saving requirements of portable devices. It complements the water storage function of the water storage tank 5 and improves the practicality of the air-to-water generator of this utility model.

[0039] like Figure 6 and Figure 7 As shown, the foldable solar charging panel 2 can be fixed together with the backpack 1. The solar charging panel 2 includes at least one set of solar panels, which are fixed to the top or outside of the backpack 1. The foldable solar charging panel 2 is preferably installed on the outside and top of the backpack 1, and can be configured to fold from the bottom or top for easy unfolding or folding. The connection between the solar charging panel 2 and the backpack 1 can be fixed by adhesive or sewing.

[0040] The foldable solar charging panel 2 can also be separated from the backpack 1. When in use, the solar charging panel 2 is connected to the energy storage battery 3 via a data cable, and the foldable solar charging panel 2 is separated from the backpack 1. The foldable solar charging panel 2 can be carried in the backpack 1. The foldable solar charging panel 2 provides a charging output port, which is convenient for charging electronic devices (such as tablets, mobile phones, etc.) when there is no power grid.

[0041] The backpack 1 is equipped with a temperature and humidity sensor connected to the control board 7 on its outer periphery. The energy storage battery 3 has a data acquisition module for collecting charging current and energy storage battery power data. The backpack 1 is also equipped with an operation panel 71 connected to the control board 7. After the operation panel 71 is powered on, it has a human-machine interface. The functions of the human-machine interface include power on / off, displaying the collected data, prompting to replace the energy storage battery 3, replacing the water filter, operating and controlling water output, alarming abnormalities and prompting abnormal information. The collected data includes ambient temperature, humidity, charging current, energy storage battery power, water volume in the water tank, and the current status of the air-to-water generator.

[0042] like Figure 2 As shown, the water outlet 12 includes a first water outlet 12A and a second water outlet 12B. The first water outlet 12A and the second water outlet 12B are arranged vertically at intervals on the same side of the backpack 1. The first water outlet 12A is connected to the water filter assembly 6 through a water pipe, and the second water outlet 12B is directly connected to the water storage tank 5 through a water pipe. This design allows users to choose whether to filter the water according to their actual needs. When they need to drink the water in the water storage tank 5 directly, they can get water through the first water outlet 12A. When they need to use other water, they can directly obtain unfiltered water from the water storage tank 5. This not only extends the service life of the filter element in the water filter assembly 6, but also saves electricity.

[0043] The foldable solar charging panel 2 efficiently collects solar energy and converts it into electrical energy to charge the energy storage battery 3 inside the backpack 1, thus solving the energy supply problem. The air filter 11 and water making component 4 utilize the moisture in the air and convert it into potable water. Its working principle is as follows: the air in the environment is purified by the air filter 11, and then water is produced by the water making component 4. The water is stored in the water tank 5. The control board 7 collects and displays real-time data, such as ambient temperature, humidity, and the power of the energy storage battery 3. Through the human-machine interface, users can easily operate the equipment and receive equipment status and abnormal information prompts, further ensuring the reliability of the equipment and the user's safe drinking water needs.

[0044] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
