[0002] Most of the water resources on the earth enter the air in the form of evaporation. The water content in the air is about 10 times that of the surface fresh water resources. Moreover, even in the border environment where the relative humidity is often only 30% RH, the water content in the air can reach 9.9g / m 3 Therefore, air can be used as an important reservoir for obtaining fresh water.

[0031] Please refer to Figure 1-7 :

[0032] The present invention provides an adsorption-type air water extraction device, comprising a housing 100, an adsorption mechanism, and a condensation mechanism. Housing 100 includes an adsorption chamber 001 and a condensation chamber 002, which are connected. A first fan 110 is mounted on the side of housing 100 corresponding to adsorption chamber 001, and a vent 120 is mounted on the other side of housing 100 opposite first fan 110. An exhaust hole 130 is mounted on the side of housing 100 corresponding to condensation chamber 002, which is connected to condensation chamber 002. The adsorption mechanism is configured to absorb water from the air. The adsorption mechanism is mounted within adsorption chamber 001, and a second fan 140 is mounted on the side of housing 100 corresponding to adsorption chamber 001. The adsorption mechanism includes a water-absorbing material layer 234. The condensation mechanism is configured to condense water vapor desorbed by heating from the adsorption mechanism into water, which is then dripped into condensation chamber 002. The condensation mechanism is mounted on the housing 100 having the exhaust hole 130.

[0033] In this embodiment, the water-absorbing material layer 234 is composed of a material capable of absorbing water from the air, such as a metal-organic framework (MOF) material. MOFs have an extremely high specific surface area, tunability, and extensive chemical variability, resulting in excellent atmospheric water capture capabilities and low regeneration energy consumption at low relative humidity. The first fan 110 acts as an air intake fan, bringing air into the adsorption chamber 001 when adsorbing water from the air. The second fan 140 acts as a desorption fan, ventilating the adsorption chamber 001 when desorbing water from the water-absorbing material layer 234.

[0034] In this embodiment, the adsorption mechanism includes a support assembly 210 and a plurality of parallel heating adsorption assemblies. The support assembly 210 is used to mount the heating adsorption assemblies. The heating adsorption assembly includes a heating plate 220 and an adsorption plate 230. The adsorption plate 230 is located above the heating plate 220. The adsorption plate 230 includes a nylon frame 231, a polytetrafluoroethylene membrane 232, and an aluminum foil 233. The polytetrafluoroethylene membrane 232 and the aluminum foil 233 are located on opposite sides of the nylon frame 231, respectively. A water-absorbing material layer 234 is filled within the nylon frame 231. The heating plate 220 includes a silicone plate 221 and an aluminum plate 222. The silicone plate 221 is fixed to the surface of the aluminum plate 222, and the silicone plate 221 and the aluminum foil 233 are opposite each other. This allows the heating plate 220 to heat the adsorption plate 230 and release the water absorbed in the water-absorbing material layer 234.

[0035] In this embodiment, the support assembly 210 includes support uprights 211, cross bars 212 and mounting assemblies 213. There are four support uprights 211. The cross bars 212 are installed between two support uprights 211. The number of mounting assemblies 213 is equal to the number of heating adsorption assemblies. The mounting assemblies 213 are installed on the four support uprights 211. The support uprights 211, the cross bars 212 and the mounting assemblies 213 are assembled to form a mounting frame for installing the heating adsorption assembly.

[0036] In this embodiment, the mounting assembly 213 includes two opposing mounting plates, each with a U-shaped groove 2130. The U-shaped grooves 2130 of the two mounting plates within the same mounting assembly are positioned opposite each other. The opposing ends of the heating and adsorption assembly are inserted into the U-shaped grooves 2130 of the two mounting plates. Each mounting plate has mounting holes at its opposing ends, and the support poles 211 are inserted into the mounting holes to facilitate mounting the mounting plates on the support poles 211.

[0037] In this embodiment, a waterproof panel 400 is provided between adsorption chamber 001 and condensation chamber 002. A third fan 410 is mounted on waterproof panel 400, serving as a ventilation fan between adsorption chamber 001 and condensation chamber 002. Waterproof panel 400 is made of polytetrafluoroethylene (PTFE), which effectively prevents water vapor in high-temperature, high-humidity air from condensing on its inner wall.

[0038] In this embodiment, a water storage box 500 is provided at the lower portion of the condensation chamber 002 , and a water outlet 510 is provided at the bottom of the water storage box 500 . Condensed water formed in the condensation chamber 002 drips into the water storage box 500 , is collected, and is discharged through the water outlet 510 .

[0039] In this embodiment, the condensation mechanism includes a cooling aluminum block 310, a heat dissipation copper tube 320, a fourth fan 330, and a semiconductor chip 340. The cooling aluminum block 310 is mounted on the inner wall of the condensation chamber 002, which has an exhaust hole 130, and the position of the cooling aluminum block 310 corresponds to the position of the exhaust hole 130. There are two sets of heat dissipation copper tubes 320, and the fourth fan 330 is installed between the two sets of heat dissipation copper tubes 320. The cooling aluminum block 310 is connected to the heat dissipation copper tubes 320 and the semiconductor chip 340. The heat dissipation copper tubes 320 and the fourth fan 330 are both located outside the housing 100. The condensation mechanism is capable of condensing high-temperature, high-humidity air entering the condensation chamber 002 from the adsorption chamber 001 into water droplets. Specifically, a mounting platform 150 is fixed to the outside of the housing 100, and the heat dissipation copper tubes 320 and the fourth fan 330 are both mounted on the mounting platform 150.

[0040] In this embodiment, a thermal insulation layer 600 is installed on the casing 100 corresponding to the adsorption chamber 001 and the condensation chamber 002. The thermal insulation layer 600 is made of nitrile rubber material and is used to reduce heat dissipation of the casing 100 when desorbing water adsorbed in the water-absorbing material layer 234.

[0041] In this embodiment, a control panel 710 and a power supply 720 are installed outside the casing 100. The aluminum plate 222 and the condensation mechanism in the adsorption mechanism of the first fan 110, the second fan 140, the third fan 410, and the fourth fan 330 are electrically connected to the control panel 710, and the power supply 720 is electrically connected to the control panel 710.

[0042] In this embodiment, the adsorption-type air-water extraction device also includes a solar power generation mechanism 800. This mechanism utilizes a conventional solar power generation device and will not be described in detail here. A power source 720 is mounted on the housing 100, and the solar power generation mechanism 800 is electrically connected to the power source 720. This fully utilizes renewable energy and ensures that the device can be used even when power is unavailable.

[0043] In the adsorption-type air water extraction device of the present invention, during the adsorption working stage, the first fan 110 is turned on, and the second fan 140 and the heating plate 220 are turned off. External air enters the adsorption mechanism under the action of the first fan 110, passes through the polytetrafluoroethylene membrane 232 and enters the metal organic framework water-absorbing material. The metal organic framework water-absorbing material absorbs water vapor in the external air, and the air after the water vapor is adsorbed is discharged from the adsorption chamber through the vent 120.

[0044] During the desorption stage, the first fan 110 is turned off, the vent 120 is sealed, and the second fan 140, the third fan 410, the heating plate 220 and the condensing mechanism are turned on. The second fan 140 drives the outside air into the interior of the adsorption mechanism, and the heating plate 220 continuously heats the adsorption plate 230, causing the moisture adsorbed by the metal organic framework water-absorbing material to be desorbed and converted into water vapor. The water vapor is integrated into the air entering the adsorption bed 3 to form high-temperature and high-humidity air. The third fan 410 drives the high-temperature and high-humidity air into the condensation chamber 002. The high-temperature and high-humidity air encounters the cooling aluminum block 310 and condenses into water droplets that drip into the water storage box 500 below. The condensed air is discharged from the condensation chamber through the exhaust hole 130, and the cold air in the condensation chamber 2 is discharged at the same time. The condensation mechanism can be cooled by the heat dissipation copper tube 320, and the condensed water is discharged through the water outlet 510.

[0045] The adsorption-type air water extraction device of the utility model has a built-in water-absorbing material with strong water absorption performance. The water-absorbing material can absorb moisture in the air and has excellent atmospheric water capture ability under low relative humidity. It can actively absorb and preserve air moisture under extreme arid conditions such as deserts and borders. Combined with the device's efficient desorption and condensation functions, the water extraction cycle can be greatly shortened.
