When the adsorption bed is in a water absorption state, the adsorption bed absorbs water in the air introduced from outside. When the adsorption bed is in a water release state, the upper portion of the inner cavity is communicated with one end of the adsorption bed, the other end of the adsorption bed is communicated with the upper portion of the side cavity, the lower portion of the inner cavity is communicated with the lower portion of the side cavity, and under the action of the thermoelectric refrigerator, the spiral fin rotates to heat and deliver the air in the inner cavity to the adsorption bed.

Description

Technical Field

[0001] This invention relates to the field of air-to-water technology, and in particular to a solar-powered air-to-water system and equipment. Background Technology

[0002] Air-to-water technology, as an emerging method of water resource acquisition, has significant application value in arid and water-scarce regions, field operations, and emergency disaster relief scenarios, enabling the direct extraction of moisture from the atmosphere to address water shortages. Currently, existing air-to-water technologies are mainly divided into two categories: thermoelectric cooling and solar adsorption. Thermoelectric cooling systems primarily consist of a thermoelectric cooling module, a heat dissipation module, an air-to-water module, and a collector. Utilizing the Peltier effect, direct current drives the thermoelectric module to generate a temperature difference, lowering the cold end temperature below the air dew point temperature, thereby condensing water vapor in the air into liquid water. Solar adsorption systems employ core components such as an adsorption bed, solar vacuum collectors, a condenser, and a water collector. An adsorbent adsorbs moisture from the air, and solar energy heats the adsorbent to release the moisture. Finally, the condenser converts the water vapor into liquid water. Both technologies are designed around the basic process of "air water extraction - purification - storage," effectively addressing water supply needs in specific environments.

[0003] In thermoelectric refrigeration systems, condensate droplets adhering to the condenser surface absorb its cooling energy, causing the cold end temperature to rise and affecting the condenser's condensation efficiency, resulting in additional energy consumption. Furthermore, the water film formed by condensation creates thermal resistance, which also affects the condenser's heat exchange efficiency and condensation effect, further impacting the overall system performance.

[0004] The information disclosed in the background section of this invention is intended only to enhance the understanding of the general background of this invention, and should not be construed as an admission or in any way implying that such information constitutes prior art known to those skilled in the art. Summary of the Invention

[0005] Therefore, it is necessary to provide a solar-powered air-to-water system and equipment to address the problems existing in current thermoelectric refrigeration systems.

[0006] The above objectives are achieved through the following technical solutions:

[0007] A solar-powered air-to-water device includes a housing containing an intermediate tank and an adsorption bed. The intermediate tank is vertically positioned with an inner cylinder rotatably mounted on its interior, coaxial with the intermediate tank. The inner cylinder has a vertically penetrating cavity, and a vertically penetrating side cavity is formed between the inner cylinder and the intermediate tank. The lower part of the inner cavity communicates with the lower part of the side cavity. A thermoelectric cooler is embedded in the side wall of the inner cylinder. Spiral blades are located on the inner wall of the inner cylinder, and condenser plates are located on the outer wall. When the thermoelectric cooler operates, it heats the inner wall and spiral blades of the inner cylinder and cools the outer wall and condenser plates. A drain pipe connected to the lower part of the side cavity is located at the bottom of the intermediate tank. A drive unit is also provided within the housing to rotate the inner cylinder relative to the intermediate tank. The adsorption bed has a water-absorbing state and a water-discharging state. In the water-absorbing state, the adsorption bed absorbs moisture from the air introduced from the outside. In the water-discharging state, the upper part of the inner cavity is connected to one end of the adsorption bed, and the other end of the adsorption bed is connected to the upper part of the side cavity. The drive unit rotates the inner cylinder, spiral blades, and condenser plates.

[0008] Furthermore, two adsorption beds are set up, and the two adsorption beds alternately operate in water absorption and water release states.

[0009] Furthermore, the box is also equipped with a water storage tank connected to the drain pipe. The water storage tank is equipped with a displacement sensor, which is used to detect the rising speed of the liquid level in the water storage tank. When the rising speed is greater than or equal to a preset value, the drive unit increases the rotation speed of the inner cylinder. When the rising speed is less than the preset value, the adsorption bed in the water discharge state switches to the water absorption state, and the adsorption bed in the water absorption state switches to the water discharge state.

[0010] Furthermore, the box is also equipped with telescopic components, which are used to bring the two adsorption beds closer to each other or further apart, and the two adsorption beds can be brought close enough to contact each other.

[0011] Furthermore, the condenser plate is spiral-shaped.

[0012] Furthermore, the inner wall of the intermediate tank is formed with vertically arranged water guide channels, and multiple water guide channels are evenly distributed along the circumference of the intermediate tank.

[0013] Furthermore, the bottom wall of the intermediate tank gradually decreases from the center to the edge, and the drain pipe is located at the edge of the bottom wall of the intermediate tank.

[0014] Furthermore, the thermoelectric cooler is cylindrical and coaxially arranged with the inner cylinder.

[0015] Furthermore, the enclosure is equipped with a dust collection box, which is used to remove dust from the air that is brought in from the outside.

[0016] This invention also provides the following technical solutions:

[0017] A solar-powered air-to-water system includes:

[0018] A processor that controls the switching of the adsorption bed between water absorption and water discharge states;

[0019] Solar panels are used to power thermoelectric coolers.

[0020] The present invention has at least the following beneficial effects:

[0021] (1) When in the water absorption state, the adsorption bed adsorbs the moisture in the air introduced from the outside. When in the water release state, the upper part of the inner cavity is connected to one end of the adsorption bed, the other end of the adsorption bed is connected to the upper part of the side cavity, and the lower part of the inner cavity is connected to the lower part of the side cavity. At the same time, the driving part makes the inner cylinder, spiral blade and condenser rotate. Under the action of the thermoelectric cooler, the spiral blade heats the air in the inner cavity and transports it to the adsorption bed. The moisture in the adsorption bed is released in the form of steam and forms condensate droplets on the outer wall of the inner cylinder and the condenser. At the same time, the condenser rotates to throw the condensate droplets to the inner wall of the intermediate tank and fall to the drain pipe for collection. To a certain extent, the absorption of the condensate droplets by the condenser is reduced, the temperature of the condenser rises and affects the condensation effect, and the energy consumption is reduced. At the same time, the thermal resistance caused by the formation of water film on the condenser is avoided, the heat exchange efficiency and condensation effect are guaranteed, and the overall performance of the system is further guaranteed.

[0022] (2) When the rising speed of the liquid level in the water storage tank is greater than or equal to the preset value, it indicates that there is more water in the adsorption bed that is currently in the water discharge state. The rotation speed of the inner cylinder is increased by the drive unit to improve the efficiency of throwing the condensed water droplets to the inner wall of the intermediate tank, further reducing the absorption of cold energy by the condensed water droplets on the condenser plate, avoiding the temperature rise of the condenser plate and affecting the condensation effect, and reducing energy consumption. It also avoids the thermal resistance caused by the formation of a water film on the condenser plate, ensuring heat exchange efficiency and condensation effect, ensuring the overall performance of the system, and accelerating the gas flow in the inner cavity and side cavity to improve water production efficiency. When the rising speed of the liquid level in the water storage tank is less than the preset value, it indicates that there is less water in the adsorption bed that is currently in the water discharge state. The adsorption bed in the water discharge state is switched to the water absorption state, and the adsorption bed in the water absorption state is switched to the water discharge state, thereby ensuring a continuously high water production efficiency.

[0023] (3) The telescopic component keeps the two adsorption beds away from each other to carry out the water production process. When the rising speed of the liquid level in the water storage tank is less than the preset value, the temperature of the adsorption bed in the water absorption state is lower and the temperature of the adsorption bed in the water discharge state is higher. The telescopic component allows the two adsorption beds to approach each other until they come into contact, and the two adsorption beds exchange heat, which raises the temperature of the adsorption bed in the water absorption state to facilitate the subsequent water discharge process, and lowers the temperature of the adsorption bed in the water discharge state to facilitate the subsequent water absorption process, thereby improving the energy utilization rate.

Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

[0035] like Figures 1 to 5 As shown, this embodiment of the invention provides a solar-powered air-to-water device, including a housing 101. The housing 101 contains an intermediate tank 102 and an adsorption bed 103. The intermediate tank 102 is vertically arranged and has an inner cylinder 201 rotatably mounted thereon. The inner cylinder 201 has a vertically penetrating inner cavity, and a vertically penetrating side cavity is formed between the inner cylinder 201 and the intermediate tank 102. The lower part of the inner cavity communicates with the lower part of the side cavity. A thermoelectric cooler 202 is embedded in the side wall of the inner cylinder 201. The inner wall of the inner cylinder 201 has spiral blades 203, and the outer wall of the inner cylinder 201 has condensing fins 204. When the thermoelectric cooler 202 operates, it can condense the water inside the inner cylinder. The inner wall of the inner cylinder 201 and the spiral blades 203 are heated, which cools the outer wall of the inner cylinder 201 and the condenser fins 204. The bottom of the intermediate tank 102 is also provided with a drain pipe 205 that communicates with the lower part of the side cavity. The box body 101 is also provided with a drive unit for rotating the inner cylinder 201 relative to the intermediate tank 102. The adsorption bed 103 has a water absorption state and a water discharge state. When it is in the water absorption state, the adsorption bed 103 adsorbs moisture from the air introduced from the outside. When it is in the water discharge state, the upper part of the inner cavity is connected to one end of the adsorption bed 103, and the other end of the adsorption bed 103 is connected to the upper part of the side cavity. The drive unit causes the inner cylinder 201, the spiral blades 203 and the condenser fins 204 to rotate.

[0036] When in the water-absorbing state, the adsorption bed 103 adsorbs moisture from the air introduced from the outside. When in the water-discharging state, the upper part of the inner cavity is connected to one end of the adsorption bed 103, the other end of the adsorption bed 103 is connected to the upper part of the side cavity, and the lower part of the inner cavity is connected to the lower part of the side cavity. At the same time, the driving unit causes the inner cylinder 201, the spiral blades 203, and the condenser 204 to rotate. Under the action of the thermoelectric cooler 202, the spiral blades 203 heat the air in the inner cavity and transport it to the adsorption bed 103. The moisture in the adsorption bed 103 is in the form of steam. The water is released and condensation droplets form on the outer wall of the inner cylinder 201 and the condenser plate 204. At the same time, the condenser plate 204 rotates to throw the condensation droplets onto the inner wall of the intermediate tank 102 and fall into the drain pipe 205 for collection. This reduces the absorption of cold energy by the condensation droplets on the condenser plate 204 to a certain extent, avoids the temperature rise of the condenser plate 204 from affecting the condensation effect, and reduces energy consumption. It also avoids thermal resistance caused by the formation of a water film on the condenser plate 204, ensuring heat exchange efficiency and condensation effect, and further ensuring the overall performance of the system.

[0037] The solar-powered air-to-water device of this application also includes a support frame 104, on which a housing 101 is mounted. One side of the housing 101 has a door for easy maintenance and repair. The adsorption bed 103 includes a bed body and an adsorbent. The bed body is typically made of corrosion-resistant metal materials, such as stainless steel or aluminum alloy, to withstand temperature changes and humidity erosion during circulation. The adsorbent can be silica gel, zeolite molecular sieves, activated alumina, or metal-organic framework materials, etc., and is filled inside the bed body in granular, honeycomb, or integral coating form. The adsorption bed 103 may also be equipped with heat exchange / conducting structures, such as heat exchange fins. The adsorption bed 103 has an air inlet and an air outlet. A fan is installed on the housing 101 to introduce outside air into the adsorption bed 103 from the air inlet. The adsorbent physically adsorbs water vapor molecules from the air, at which point the adsorption bed 103 is in a water-absorbing state until its adsorption capacity decreases to the point where it can no longer adsorb. When heated air from the inner cavity is delivered to the adsorption bed 103, the van der Waals forces between the adsorbent and water molecules weaken, and the water molecules detach from the surface of the adsorbent. At this time, the adsorption bed 103 is in a water-discharging state. The structure and working principle of the adsorption bed 103 described above are existing technologies and will not be elaborated here.

[0038] The intermediate tank 102 has a through hole at the center of its top wall, through which the upper part of its inner cavity connects to one end of the adsorption bed 103. The lower part of the inner cylinder 201 has a side hole 206, through which the lower part of the inner cavity connects to the lower part of the side cavity, enabling air circulation. A channel is formed in the center of the spiral vane 203 to allow vertical circulation within the inner cavity. A gap exists between the outer side of the condenser vane 204 and the inner wall of the intermediate tank 102, allowing vertical circulation within the side cavity. The drive unit includes a motor equipped with a corresponding power supply and control module to control start-up, shutdown, and operating conditions. The motor drives the inner cylinder 201 to rotate relative to the intermediate tank 102 via a gear structure.

[0039] In one embodiment, two adsorption beds 103 are provided, and the two adsorption beds 103 alternately operate in a water absorption state and a water release state.

[0040] When one adsorption bed 103 is in the water absorption state, the other is in the water discharge state, ensuring that the equipment can continuously produce water.

[0041] Among them, see Figures 2 to 4 Corresponding pipelines 105 are provided between the two adsorption beds 103 and between the adsorption bed 103 and the intermediate tank 102. Solenoid valves 110 can be installed on different pipelines 105 to control the opening and closing of the corresponding pipelines 105. The specific arrangement of the pipelines 105 and the solenoid valves 110 are existing technologies and will not be described in detail here. The two adsorption beds 103 are arranged opposite each other. Each adsorption bed 103 has an air inlet at the upper end and an air outlet at the lower end. An exhaust port 106 is provided on the pipeline 105 connected to the air outlet.

[0042] For example, such as Figure 3 As shown, the adsorption bed 103 on the left is in a water-absorbing state. The external air is controlled to flow along path a by the corresponding solenoid valve 110. The moisture in the air is adsorbed by the adsorption bed 103 on the left, while the dry air is discharged from the exhaust port 106 on the exhaust end side of the adsorption bed 103 on the left. At this time, the adsorption bed 103 on the right side is in the water discharge state. The upper part of the inner cavity is connected to one end of the adsorption bed 103 on the right side through the corresponding solenoid valve 110. The other end of the adsorption bed 103 on the right side is connected to the upper part of the side cavity. At the same time, the lower part of the inner cavity is connected to the lower part of the side cavity. The motor drives the inner cylinder 201, the spiral blade 203 and the condenser 204 to rotate. Under the action of the thermoelectric cooler 202, the spiral blade 203 heats the air in the inner cavity and delivers it to the adsorption bed 103 on the right side. The water in the adsorption bed 103 on the right side is released in the form of steam and forms condensate droplets on the outer wall of the inner cylinder 201 and the condenser 204. At the same time, the condenser 204 rotates to throw the condensate droplets to the inner wall of the intermediate tank 102 and fall to the drain pipe 205 for collection. During this process, the air or water vapor in the inner cavity, the side cavity and the adsorption bed 103 on the right side flows along path b.

[0043] like Figure 4 As shown, the adsorption bed 103 on the right is in a water-absorbing state. The external air is controlled to flow along path c by the corresponding solenoid valve 110. The moisture in the air is adsorbed by the adsorption bed 103 on the right, while the dry air is discharged from the exhaust port 106 on the exhaust end side of the adsorption bed 103 on the right. At this time, the adsorption bed 103 on the left is in the water discharge state. The upper part of the inner cavity is connected to one end of the adsorption bed 103 on the left through the corresponding solenoid valve 110. The other end of the adsorption bed 103 on the left is connected to the upper part of the side cavity. At the same time, the lower part of the inner cavity is connected to the lower part of the side cavity. The motor drives the inner cylinder 201, the spiral blade 203 and the condenser 204 to rotate. Under the action of the thermoelectric cooler 202, the spiral blade 203 heats the air in the inner cavity and delivers it to the adsorption bed 103 on the left. The water in the adsorption bed 103 on the left is released in the form of steam and forms condensate droplets on the outer wall of the inner cylinder 201 and the condenser 204. At the same time, the condenser 204 rotates to throw the condensate droplets to the inner wall of the intermediate tank 102 and fall to the drain pipe 205 for collection. During this process, the air or water vapor in the inner cavity, the side cavity and the left side adsorption bed 103 flows along the path d.

[0044] In one embodiment, the housing 101 is further provided with a water storage tank 107 connected to the drain pipe 205. The water storage tank 107 is provided with a displacement sensor 207. The displacement sensor 207 is used to detect the rising speed of the liquid level in the water storage tank 107. When the rising speed is greater than or equal to a preset value, the drive unit increases the rotation speed of the inner cylinder 201. When the rising speed is less than the preset value, the adsorption bed 103 in the water discharge state switches to the water absorption state, and the adsorption bed 103 in the water absorption state switches to the water discharge state.

[0045] When the rising speed of the liquid level in the water storage tank 107 is greater than or equal to the preset value, it indicates that there is a lot of water in the adsorption bed 103, which is currently in the water discharge state. The rotation speed of the inner cylinder 201 is increased by the drive unit to improve the efficiency of throwing the condensed water droplets onto the inner wall of the intermediate tank 102, further reducing the absorption of cold energy by the condensed water droplets on the condenser plate 204, avoiding the temperature rise of the condenser plate 204 and affecting the condensation effect, and reducing energy consumption. It also avoids the thermal resistance caused by the formation of a water film on the condenser plate 204, ensuring heat exchange efficiency and condensation effect, ensuring the overall performance of the system, and accelerating the gas flow in the inner cavity and side cavity to improve water production efficiency. When the rising speed of the liquid level in the water storage tank 107 is less than the preset value, it indicates that there is less water in the adsorption bed 103, which is currently in the water discharge state. The adsorption bed 103 in the water discharge state is switched to the water absorption state, and the adsorption bed 103 in the water absorption state is switched to the water discharge state, thereby ensuring a continuously high water production efficiency.

[0046] It is worth noting that when the rising speed of the liquid level in the water storage tank 107 is initially greater than or equal to a preset value, and then falls below the preset value after a certain period of time, it indicates that the water in the adsorption bed 103, which is currently in the water-discharging state, is gradually being released and decreasing. At this time, it is necessary to switch the adsorption bed 103 from the water-discharging state to the water-absorbing state, and vice versa. Conversely, when the rising speed of the liquid level in the water storage tank 107 is consistently less than the preset value, it indicates that the water in the adsorption bed 103, which is currently in the water-discharging state, is already low. Therefore, it is also necessary to increase the rotation speed of the inner cylinder 201 through the drive unit to ensure a certain water production efficiency.

[0047] The water storage tank 107 is located below the intermediate tank 102, and the two are connected by a drain pipe 205. The displacement sensor 207 is located on the top wall of the water storage tank 107, and a discharge pipe with a valve is located on the bottom wall of the water storage tank 107. The working principle and installation method of the displacement sensor 207 are existing technologies and will not be described in detail here.

[0048] In one embodiment, see Figure 2 The housing 101 is also equipped with a telescopic component 208, which is used to bring the two adsorption beds 103 closer to each other or further apart, and the two adsorption beds 103 can be brought close to each other until they come into contact.

[0049] The telescopic component 208 keeps the two adsorption beds 103 apart to facilitate the water production process. When the rising rate of the liquid level in the water storage tank 107 is less than a preset value, the temperature of the adsorption bed 103 in the water absorption state is lower, and the temperature of the adsorption bed 103 in the water discharge state is higher. The telescopic component 208 allows the two adsorption beds 103 to approach each other until they come into contact, and the two adsorption beds 103 exchange heat. This causes the temperature of the adsorption bed 103 in the water absorption state to rise, so as to facilitate the subsequent water discharge process, and the temperature of the adsorption bed 103 in the water discharge state to drop, so as to facilitate the subsequent water absorption process, thereby improving energy utilization.

[0050] The telescopic component 208 can be a hydraulic cylinder or an electric push rod, and is equipped with a corresponding power source and control module to control start-up, shutdown, and operating conditions. See also... Figures 2 to 4 The output end of the telescopic component 208 is fixed to the adsorption bed 103 on the left. Simultaneously, a telescopic tube should be installed at the corresponding pipe 105 to accommodate the relative movement of the adsorption bed 103 on the left and right sides, ensuring a tight seal. Furthermore, both adsorption beds 103 can be box-shaped. When the two adsorption beds 103 approach each other, they will be in surface contact, increasing the contact area and improving heat exchange efficiency.

[0051] It is understood that the solar-powered air-to-water device of this application also includes a processor, which is connected to the control module of the motor, the control module of the telescopic component 208, all solenoid valves 110, the fan, and the displacement sensor 207 for system operation control. The specific configuration of the processor is prior art and will not be described in detail here.

[0052] In one embodiment, the condenser plate 204 is spiral-shaped.

[0053] When the spiral-shaped condenser plate 204 rotates, it conveys the condensate droplets downwards, thereby accelerating the collection of the condensate droplets.

[0054] In other embodiments not shown, the condenser plate 204 may also be in the shape of a disc or fin, in which case it does not have the function of conveying condensed water droplets downwards.

[0055] In one embodiment, the inner wall of the intermediate tank 102 is formed with vertically arranged water guide grooves 209, and multiple water guide grooves 209 are evenly distributed along the circumference of the intermediate tank 102.

[0056] The condenser plate 204 rotates to throw the condensate droplets along the tangent of the condenser plate 204 onto the inner wall of the intermediate tank 102, so that the condensate droplets collect in the water guide trough 209 and fall into the drain pipe 205 for collection, so as to further accelerate the collection of condensate droplets.

[0057] The lower end of the water guide trough 209 extends to the bottom wall of the intermediate tank 102, so that the condensate droplets in the water guide trough 209 can fall onto the bottom wall of the intermediate tank 102 and be discharged through the drain pipe 205.

[0058] In one embodiment, the bottom wall of the intermediate tank 102 gradually decreases from the center to the edge, and the drain pipe 205 is disposed at the edge of the bottom wall of the intermediate tank 102.

[0059] The condensate dripping from the inner wall of the intermediate tank 102 falls to the bottom wall and is then easily collected at the drain pipe 205.

[0060] Preferably, the bottom wall has the lowest point where the drain pipe 205 is located, while the height gradually decreases from other locations to the drain pipe 205, which further facilitates the collection of condensate droplets at the drain pipe 205.

[0061] In one embodiment, the thermoelectric cooler 202 is cylindrical and coaxially arranged with the inner cylinder 201.

[0062] Accelerate the heating process of the inner wall of the inner cylinder 201 and the spiral blades 203, as well as the cooling process of the outer wall of the inner cylinder 201 and the condenser blades 204, thereby improving water production efficiency.

[0063] In one embodiment, the housing 101 is provided with a dust removal box 108, which is used to remove dust from the air that is introduced from the outside.

[0064] The fan draws outside air into the dust collector 108, which removes dust from the air. The dust-removed air then flows along the corresponding pipe 105 to the adsorption bed 103. The structure and working principle of the dust collector 108 are existing technologies and will not be described in detail here.

[0065] The present invention also provides the following embodiment: a solar-powered air-to-water system, comprising:

[0066] A processor is used to control the switching of the adsorption bed 103 between water absorption and water discharge states;

[0067] Solar panel 109 is used to power thermoelectric cooler 202.

[0068] The solar panel 109 is electrically connected to the thermoelectric cooler 202 and is equipped with a control module, which is connected to a processor. This connection method is existing technology and will not be elaborated upon here. When solar energy is abundant, the solar panel 109 can also supply power to motors and other related electrical appliances.

[0069] The working principle of this invention is as follows:

[0070] The fan introduces outside air into the dust collection box 108, which removes dust from the air. The air after dust removal flows along the corresponding pipe 105 to the adsorption bed 103.

[0071] like Figure 3 As shown, the adsorption bed 103 on the left is in a water-absorbing state. The external air is controlled to flow along path a by the corresponding solenoid valve 110. The moisture in the air is adsorbed by the adsorption bed 103 on the left, while the dry air is discharged from the exhaust port 106 on the exhaust end side of the adsorption bed 103 on the left. At this time, the adsorption bed 103 on the right side is in the water discharge state. The upper part of the inner cavity is connected to one end of the adsorption bed 103 on the right side through the corresponding solenoid valve 110. The other end of the adsorption bed 103 on the right side is connected to the upper part of the side cavity. At the same time, the lower part of the inner cavity is connected to the lower part of the side cavity. The motor drives the inner cylinder 201, the spiral blade 203 and the condenser 204 to rotate. Under the action of the thermoelectric cooler 202, the spiral blade 203 heats the air in the inner cavity and delivers it to the adsorption bed 103 on the right side. The water in the adsorption bed 103 on the right side is released in the form of steam and forms condensate droplets on the outer wall of the inner cylinder 201 and the condenser 204. At the same time, the condenser 204 rotates to throw the condensate droplets to the inner wall of the intermediate tank 102 and fall down along the water guide trough 209 to the drain pipe 205 for collection. During this process, the air or water vapor in the inner cavity, the side cavity and the adsorption bed 103 on the right side flows along path b.

[0072] like Figure 4 As shown, the adsorption bed 103 on the right is in a water-absorbing state. The external air is controlled to flow along path c by the corresponding solenoid valve 110. The moisture in the air is adsorbed by the adsorption bed 103 on the right, while the dry air is discharged from the exhaust port 106 on the exhaust end side of the adsorption bed 103 on the right. At this time, the adsorption bed 103 on the left is in the water discharge state. The upper part of the inner cavity is connected to one end of the adsorption bed 103 on the left through the corresponding solenoid valve 110. The other end of the adsorption bed 103 on the left is connected to the upper part of the side cavity. At the same time, the lower part of the inner cavity is connected to the lower part of the side cavity. The motor drives the inner cylinder 201, the spiral blade 203 and the condenser 204 to rotate. Under the action of the thermoelectric cooler 202, the spiral blade 203 heats the air in the inner cavity and delivers it to the adsorption bed 103 on the left. The water in the adsorption bed 103 on the left is released in the form of steam and forms condensate droplets on the outer wall of the inner cylinder 201 and the condenser 204. At the same time, the condenser 204 rotates to throw the condensate droplets to the inner wall of the intermediate tank 102 and fall down along the water guide trough 209 to the drain pipe 205 for collection. During this process, the air or water vapor in the inner cavity, the side cavity and the left side adsorption bed 103 flows along the path d.

[0073] The condenser plate 204 rotates to throw the condensed water droplets onto the inner wall of the intermediate tank 102, which to a certain extent reduces the absorption of cold energy by the condenser plate 204 by the condensed water droplets, avoids the temperature of the condenser plate 204 rising and affecting the condensation effect, and reduces energy consumption. At the same time, it avoids the thermal resistance caused by the formation of a water film on the condenser plate 204, ensuring heat exchange efficiency and condensation effect, and further ensuring the overall performance of the system.

[0074] The rising speed of the liquid level in the water storage tank 107 is detected by the displacement sensor 207. When the rising speed of the liquid level in the water storage tank 107 is greater than or equal to a preset value, it indicates that there is a lot of water in the adsorption bed 103, which is currently in a water discharge state. The rotation speed of the inner cylinder 201 is increased by the drive unit to improve the efficiency of throwing the condensed water droplets onto the inner wall of the intermediate tank 102, further reducing the absorption of cold energy by the condensed water droplets on the condenser plate 204, avoiding the temperature rise of the condenser plate 204 and affecting the condensation effect, and reducing energy consumption. It also avoids the thermal resistance caused by the formation of a water film on the condenser plate 204, ensuring heat exchange efficiency and condensation effect, ensuring the overall performance of the system, and accelerating the gas flow in the inner and side chambers to improve water production efficiency. When the rising speed of the liquid level in the water storage tank 107 is less than the preset value, the rising speed of the liquid level in the water storage tank 107 is lower than the preset value. When the value is specified, it indicates that the adsorption bed 103 in the current water-discharging state has less water, and the adsorption bed 103 in the water-absorbing state has a lower temperature, while the adsorption bed 103 in the water-discharging state has a higher temperature. The telescopic component 208 allows the two adsorption beds 103 to approach each other until they come into contact, and the two adsorption beds 103 exchange heat, causing the temperature of the adsorption bed 103 in the water-absorbing state to rise, so as to facilitate the subsequent water-discharging process, and the temperature of the adsorption bed 103 in the water-discharging state to drop, so as to facilitate the subsequent water-absorbing process, thereby improving energy utilization. Then, the corresponding solenoid valve 110 controls the adsorption bed 103 in the water-discharging state to switch to the water-absorbing state, and the adsorption bed 103 in the water-absorbing state to switch to the water-discharging state, thereby ensuring a continuously high water production efficiency.
