Description

Technical Field

[0001] This application belongs to the field of drinking water equipment technology, specifically relating to a water purifier and method for obtaining low-deuterium drinking water by vaporizing and recondensing water. Background Technology

[0002] Deuterium-depleted water (DDW) refers to drinking water with a deuterium content lower than the standard for natural water (approximately 150 ppm). It possesses health benefits due to its low deuterium content, small molecular clusters, and rich mineral content, offering significant advantages in terms of health value. Natural dew, a product of the natural condensation of atmospheric water vapor in a clean environment, is characterized by low deuterium content (130-145 ppm), small molecular cluster structure (50-75 Hz), a weakly alkaline to neutral pH value (6.4-8.5), and the presence of various beneficial trace elements such as potassium, calcium, magnesium, manganese, iron, zinc, and selenium.

[0003] Existing technologies for preparing deuterium-rich water mainly include multi-stage distillation, electrolysis, and membrane separation. Multi-stage distillation utilizes multiple vaporization-condensation cycles to cumulatively reduce deuterium levels, decreasing the concentration from 150 ppm to 10-50 ppm. However, it requires high-temperature heating, resulting in enormous energy consumption, and the equipment is complex and expensive. Electrolysis leverages the fact that H₂O is more easily electrolyzed than HDO, producing hydrogen with extremely low deuterium content. This hydrogen is then burned with oxygen to generate deuterium-rich water, but it is also extremely energy-intensive and only suitable for small-scale, high-purity heavy water production. Membrane separation utilizes the selective permeability of special membranes to different isotopes of water molecules for separation. However, the membrane materials have limited selectivity, low flux, and high cost. All of these industrial methods suffer from high energy consumption, complex equipment, and high costs, making them unsuitable for civilian applications such as homes and offices.

[0004] Air-to-water technology, as a novel water supply method that extracts moisture from ambient air, has been gradually applied to household drinking water, field operations, emergency rescue, and water-scarce areas such as islands and deserts. The basic working principle of existing air-to-water generators typically involves using a fan to draw ambient air into the machine. The air first flows through an evaporator, where a low-temperature refrigerant lowers the air temperature below the dew point, causing water vapor in the air to condense into water droplets. These droplets are then collected and filtered to obtain drinking water. However, the water produced by existing air-to-water generators is usually purified water or simply mineralized water. Its physicochemical properties and trace mineral composition differ significantly from natural dew, failing to replicate the unique health benefits of natural dew, such as low deuterium content, small molecular clusters, and balanced mineral composition.

[0005] Therefore, there is an urgent need for a low-deuterium drinking water purifier that combines water vaporization to reduce deuterium with air-to-water condensation. Summary of the Invention

[0006] In view of this, this application provides a water purifier and method for obtaining low-deuterium drinking water by vaporizing and recondensing water, in order to solve the problems of high energy consumption and complex equipment in existing low-deuterium water preparation technologies.

[0007] To solve the above problems, the technical solution adopted in this application is as follows:

[0008] In a first aspect, this application proposes a water purifier for obtaining low-deuterium drinking water through water vaporization and recondensation, comprising a condensation water purification device and a vaporization deuteration device, wherein the outlet of the vaporization deuteration device is connected to the inlet of the condensation water purification device; the vaporization deuteration device comprises a purified water tank, wherein the purified water tank comprises a dry air inlet, a humidified air outlet, and a vaporization water curtain disposed between the dry air inlet and the humidified air outlet.

[0012] Furthermore, the condensation water production device includes a clay pot, a water production system, a water purification system, and a main control board; the condensation water production device is provided with a water outlet; the clay pot is connected to the condensation water production device; the water production system is used to condense the low-deuterium water vapor output by the vaporization deuterium reduction device into liquid low-deuterium water; the water inlet of the water purification system is connected to the water outlet of the water production system, and the water outlet of the water purification system is connected to the clay pot; the main control board is electrically connected to the water production system and the water purification system respectively; and / or, the main control board is also electrically connected to the vaporization fan and the water vapor deuterium value sensor, used to adjust the speed of the vaporization fan according to the deuterium content parameter detected by the water vapor deuterium value sensor; and / or, the main control board is also electrically connected to the temperature and humidity sensor, the vaporization fan, and the water supply pump, used to control the start and stop of the vaporization fan and the water supply pump according to the ambient temperature and humidity data detected by the temperature and humidity sensor.

[0013] Furthermore, the condensate water production device is provided with a support ring and a support platform, and the purple clay tank is placed on the support platform and fixed by the support ring; and / or, the condensate water production device also includes a cabinet panel; and / or, the side or back of the condensate water production device is provided with a heat dissipation grille, and the heat dissipation grille is provided in a manner corresponding to the heat dissipation side of the water production system.

[0014] Furthermore, the water production system includes an evaporative condenser unit, a radiator, a compressor, and a water collection pan; the evaporator and condenser in the evaporative condenser unit are integrated and arranged sequentially along the airflow direction, and are configured so that the low-deuterium water vapor first passes through the evaporator to condense and produce water, and then passes through the condenser to recover the cooling capacity of the air to the refrigerant; the water collection pan is connected below the evaporative condenser unit to collect condensate; the compressor is connected to both the evaporator and the condenser, and the radiator is located on the heat dissipation side of the condenser.

[0015] Furthermore, the water purification system includes a first purification filter assembly, a booster pump, and a manifold box; the first purification filter assembly is connected to the water collection tray and consists of a first purification filter, a second purification filter, and a third purification filter connected in series, respectively used for three-stage filtration and purification of condensate; the manifold box is connected to the outlet of the first purification filter assembly and is used to collect the condensate filtered by the first purification filter assembly; the inlet of the booster pump is connected to the outlet of the manifold box, and its outlet is connected to the inlet of the purple clay pot; the booster pump is configured to start after the amount of condensate in the manifold box reaches a preset water level, and pump the collected condensate into the purple clay pot; the first purification filter, the second purification filter, and the third purification filter are respectively a PP cotton filter, an activated carbon filter, and an RO reverse osmosis membrane filter.

[0016] Secondly, this application also proposes a method for obtaining low-deuterium drinking water through water vaporization and recondensation, using the water purifier described in the first aspect, comprising the following steps: Step 1: Vaporizing external water source into low-deuterium water vapor through the vaporization deuteration device, and controlling the deuterium content of the low-deuterium water vapor within the range of 100-130 ppm by adjusting the speed of the vaporization fan; Step 2: Condensing the low-deuterium water vapor into liquid low-deuterium water through the condensation water purifier, and then storing it in the purple clay vat after filtration and purification by the water purification system.

[0017] Further, step 1 includes the following specific steps: The main control board compares the deuterium content parameter detected by the water vapor deuterium value sensor with a preset low deuterium water vapor deuterium value threshold: when the deuterium content is greater than or equal to 130 ppm, the speed of the vaporization fan is controlled to 1900-2100 rpm; when the deuterium content is less than or equal to 100 ppm, the speed of the vaporization fan is controlled to 3400-3600 rpm; and / or, the main control board also controls the start and stop of the vaporization deuterium reduction device based on the detection value of the temperature and humidity sensor: when the ambient humidity is less than 55%, the vaporization deuterium reduction device is started; when the ambient humidity is greater than 65%, the vaporization deuterium reduction device is turned off.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0019] This application integrates a water vaporization and deuteration device with a condensation water treatment device, constructing an integrated closed loop from water source vaporization and deuteration to condensation purification and then to the preservation of purple clay, enabling the controllable acquisition of low-deuterium content in the produced water at normal temperature and pressure. The vaporization and deuteration device utilizes the hydrogen isotope fractionation effect during water vaporization, preferentially vaporizing ordinary water molecules into the gas phase at room temperature, while deuterium-containing water molecules remain in the liquid phase, thus obtaining low-deuterium water vapor. The fiber grid of the vaporization water curtain has extremely small pores, allowing water molecules to form an extremely thin water film on the fiber surface. Dry air penetrates the water film, achieving efficient vaporization. Simultaneously, due to the low vapor pressure and slow diffusion rate of deuterium-containing water molecules, a large amount of deuterium is trapped on the surface of the vaporization water curtain, significantly reducing the deuterium content of the delivered water vapor. The speed control of the vaporizing fan achieves a dynamic balance between deuteration reduction and water production: the higher the wind speed, the less deuterium is trapped by the vaporizing water curtain, resulting in a higher deuterium value in the discharged water vapor, but also increasing water production; conversely, the lower the wind speed, the more deuterium is trapped, resulting in a lower deuterium value, but decreasing water production. A water vapor deuterium sensor monitors the deuterium content at the outlet in real time, and the main control board adjusts the vaporizing fan speed in a closed loop based on the detected value, precisely controlling the water vapor deuterium value within the low-deuterium drinking water standard range of 100-130 ppm.

[0020] The condensation water treatment unit receives low-deuterium water vapor from the vaporization and deuteration unit, condenses it into liquid low-deuterium water through an evaporation-condensation unit, and then filters it through a three-stage purification filter assembly before storing it in a Zisha (purple clay) jar. The Zisha jar has a natural double-pore structure, with numerous closed and open pores distributed between its inner and outer walls. Utilizing its natural mineral components (such as iron, magnesium, calcium, potassium, silicon, and zinc), it raises the water's pH value from 6.5-7.0 to 7.2-7.8, serving as a natural pH regulating material. Its microporous permeability allows for trace air exchange between the water and the jar, inhibiting odors and bacterial growth, thus serving as an odor-suppressing and water-cultivating container. Furthermore, the richness of beneficial trace elements in the original Zisha clay allows for the trace dissolution of minerals into the water, serving as a mineral trace element stabilizing material.

[0021] The entire system is not a simple series connection, but rather a complete process chain from water source treatment to water quality activation, with vaporization and deuteration as the front end, condensation and water production as the middle stage, and purple clay storage as the back end. The vaporization and deuteration device provides controllable low-deuterium water vapor at the source, the condensation and water production device ensures water condensation collection and deep purification, and the purple clay tank provides a stable medium environment for subsequent reduction reactions. Compared with existing industrial low-deuterium water preparation methods, this application operates at normal temperature and pressure, without the need for high-temperature heating or high-energy-consuming electrolysis. The equipment is simple, has low operating costs, and is suitable for civilian scenarios such as homes and offices. Compared with existing air-to-water generators, the drinking water produced by this application has low-deuterium characteristics, which is closer to the health value of natural dew. The final product is low-deuterium, small molecular clusters, rich in minerals and with a balanced ratio, similar to natural dew, achieving a synergistic upgrade in safety and activity, far exceeding the effect of single water production or simple mineralization equipment, ensuring that the output water quality has both the component characteristics of natural dew and the stability and safety of mechanized production.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. The components of the embodiments of this application described and shown in the accompanying drawings can be arranged and designed in various different configurations.

All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0040] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0041] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0042] In this application, unless otherwise expressly specified and limited, "above" or "below" a second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of a second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" a second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and do not limit the number of objects; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following related objects are in an "or" relationship. Existing low-deuterium water preparation technologies generally have the following problems: First, industrial methods such as multi-stage distillation, electrolysis, and membrane separation are energy-intensive, have complex equipment, and are costly, making them unsuitable for civilian scenarios such as homes and offices; Second, the water produced by existing air-to-water generators is usually pure water or simple mineralized water, whose physicochemical indicators and mineral trace element composition differ significantly from natural dew, and cannot restore the low-deuterium, small molecular clusters, and uniformity unique to natural dew. The existing mineralization technologies are mostly filter-based instantaneous mineralization, which lacks controllability and continuity. The amount of minerals dissolved fluctuates greatly due to water temperature and flow rate, making it difficult to achieve a stable and precise mineral ratio. The existing water storage containers are mostly made of plastic or stainless steel, which do not have breathability or natural ion exchange capacity. After long-term storage, the water tastes bland and lacks vitality, and is prone to bacterial growth and odor. The existing air-to-water generators lack complete detection and closed-loop control methods for the components of natural dew, and cannot automatically adjust the mineralization and reduction process based on real-time water quality data, resulting in a low level of intelligence.

[0043] Natural dew, as a product of natural condensation of atmospheric water vapor in a clean environment, has the characteristics of low deuterium content (130-145ppm), small molecular cluster structure (50-75Hz), weakly alkaline to neutral pH value (6.4-8.5), and contains a variety of beneficial trace elements such as potassium, calcium, magnesium, manganese, iron, zinc, and selenium, giving it significant advantages in terms of health benefits when consumed.

[0044] Hydrogen isotope fractionation occurs during water vaporization—due to deuterium ( 2H, D) and protium ( 1 The mass difference between H₂O and H₂O leads to different physical behaviors of deuterated water molecules and ordinary water molecules during phase transition. At the same temperature, water molecules with different isotopic compositions have different saturated vapor pressures: H₂O > HDO > D₂O. At 25℃, the vapor pressure of H₂O is about 8.5% higher than that of HDO and about 16% higher than that of D₂O. This means that ordinary water molecules are more likely to escape from the liquid phase into the gas phase, while deuterated water molecules tend to remain in the liquid phase. When water vaporizes, the water vapor automatically "enriches" the light isotope protium while "depleting" the heavy isotope deuterium, achieving a natural deuteration effect. The lower the temperature, the smaller the fractionation coefficient α and the stronger the fractionation effect: α≈0.900 at 0℃ and α≈0.938 at boiling point 100℃. This explains why low-temperature evaporation yields water vapor with a lower deuterium content than high-temperature boiling.

[0045] This application integrates a water vaporization deuteration device with a condensation water production device, constructing an integrated closed loop from water source vaporization deuteration to condensation purification and then to the preservation of purple clay, enabling the controllable acquisition of low-deuterium content in the produced water at ambient temperature and pressure. The vaporization deuteration device utilizes the hydrogen isotope fractionation effect during water vaporization, preferentially vaporizing ordinary water molecules into the gas phase at ambient temperature, while deuterium-containing water molecules remain in the liquid phase, thus obtaining low-deuterium water vapor. The fiber grid of the vaporization water curtain has extremely small pores, allowing water molecules to form an extremely thin water film on the fiber surface. Dry air penetrates this water film, achieving efficient vaporization. Simultaneously, due to the low vapor pressure and slow diffusion rate of deuterium-containing water molecules, a large amount of deuterium is trapped on the surface of the vaporization water curtain, significantly reducing the deuterium content of the delivered water vapor. The speed control of the vaporization fan achieves a dynamic balance between the deuteration effect and the water production rate. A water vapor deuterium sensor monitors the deuterium content at the outlet in real time. The main control board adjusts the speed of the vaporizing fan in a closed loop based on the detected value, so as to accurately control the water vapor deuterium value within the low deuterium drinking water standard range of 100-130ppm.

[0046] The condensation water treatment unit receives low-deuterium water vapor from the vaporization and deuteration unit, condenses it into liquid low-deuterium water using an evaporation-condensation unit, and then filters it through a three-stage purification filter assembly before storing it in a purple clay tank. The purple clay tank has a natural double-pore structure, which allows the water to naturally breathe and activate, adsorbing impurities and releasing trace beneficial elements. It also provides a stable reaction vessel for subsequent reduction reactions, avoiding secondary impacts on water quality from metal or plastic containers. The final product is low-deuterium, small-molecule cluster water rich in minerals in a balanced ratio, similar to natural dew, achieving a synergistic upgrade in safety and activity.

[0047] The following is in conjunction with the appendix Figures 1 to 9 The technical solutions provided in this application will be described in detail through specific embodiments and application scenarios.

[0048] In a first aspect, this application proposes a water purifier for obtaining low-deuterium drinking water through water vaporization and recondensation, including a condensation water purification device 100 and a vaporization deuterium reduction device 600. The outlet of the vaporization deuterium reduction device 600 is connected to the inlet of the condensation water purification device 100. The vaporization deuterium reduction device 600 includes a purified water tank 620, which includes a drying inlet 621, a humidifying outlet 632, and a vaporization water curtain 624 disposed between the drying inlet 621 and the humidifying outlet 632.

[0049] like Figure 1 , Figure 2 and Figures 7-9 As shown, the condensation water production device 100 includes a clay pot 200, a water production system, a water purification system, and a main control board 500. The condensation water production device 100 is provided with a water outlet 110; the clay pot 200 is connected to the housing 100; the water production system is used to condense the low-deuterium water vapor output by the vaporization deuterium reduction device 600 into liquid low-deuterium water; the water inlet of the water purification system is connected to the water outlet of the water production system, and the water outlet of the water purification system 400 is connected to the clay pot 200; the main control board 500 is electrically connected to the water production system and the water purification system 400 respectively.

[0050] like Figures 3-6 As shown, the vaporization deuterium reduction device 600 is used to convert external water source into low-deuterium water vapor through room temperature vaporization. The vaporization deuterium reduction device 600 also includes a second purification filter assembly 610, a water spray tank 622, and a water supply pump 623. The outlet of the second purification filter assembly 610 is connected to the purified water tank 620. After pretreatment by the second purification filter assembly 610, the pretreated purified water enters the purified water tank 620. The inlet of the water supply pump 623 is connected to the purified water tank 620, and its outlet 110 is connected to the water spray tank 622 to supply pure water from the purified water tank 620 to the water spray tank 622. The water spray tank 622 is located above the vaporized water curtain 624. Several water spray holes are arranged at the bottom of the water spray tank 622 so that clean water flows from the water spray holes to the vaporized water curtain 624 below. The continuously injected pure water completely soaks the vaporized water curtain 624 and finally falls back into the clean water tank 620 through the bottom of the vaporized water curtain 624. This cycle repeats, keeping the vaporized water curtain 624 moist at all times.

[0051] like Figures 3-6 As shown, the vaporization deuterium reduction device 600 also includes a vaporization fan 630; the drying air inlet 621 is located on one side of the clean water tank 620, and the vaporization fan 630 is located on the other side of the clean water tank 620. It is configured to draw air in from the drying air inlet 621 and pass through the vaporization water curtain 624, mixing the fine water molecules in the fiber grid of the vaporization water curtain 624 into water vapor, which then flows through the blades of the vaporization fan 630 and is finally discharged from the vaporization deuterium reduction device 600 under the guidance of the humidified air outlet 632, thus completing the conversion of the water body from liquid phase to gas phase.

[0052] Because the fiber grid of the vaporizing water curtain 624 has extremely small pore size, the diameter of the water molecules contained within it is also smaller than the pore size, much smaller than the wavelength of visible light. Therefore, the dry air drawn in from the dry air inlet 621 and passing through it mixes with the water molecules in the fiber grid and directly vaporizes into ionic water vapor. This is a typical "natural vaporization process." According to the principle of hydrogen isotope fractionation, ordinary water molecules (H2O) are more easily vaporized during the vaporization process, while deuterium-containing water molecules (HDO, D2O) are more difficult to vaporize. This results in a large amount of deuterium being retained on the surface of the vaporizing water curtain 624. Consequently, the deuterium content of the water vapor emitted by the vaporizing water curtain 624 is greatly reduced, thus forming low-deuterium water vapor.

[0053] The vaporization deuterium reduction device 600 also includes a water vapor deuterium value sensor 631, which is used to detect the deuterium content of low-deuterium water vapor at the humidified outlet 632 of the vaporization deuterium reduction device 600.

[0054] The vaporization deuterium reduction device 600 is also equipped with a temperature and humidity sensor 510.

[0055] The main control board 500 is also electrically connected to the vaporization fan 630 and the water vapor deuterium value sensor 631, and is used to adjust the speed of the vaporization fan 630 according to the deuterium content parameter detected by the water vapor deuterium value sensor 631.

[0056] The main control board 500 is also electrically connected to the temperature and humidity sensor 510, the vaporization fan 630 and the water supply pump 623, so as to control the opening and closing of the vaporization fan 630 and the water supply pump 623 based on the ambient temperature and humidity data detected by the temperature and humidity sensor 510.

[0057] The condensate water production device 100 is equipped with a support ring 130 and a support platform 140. The purple clay tank 200 is placed on the support platform 140 and is limited and fixed by the support ring 130.

[0058] The condensate water generator 100 also includes a cabinet panel 150.

[0059] The condensate water production device 100 is provided with a heat dissipation grille 120 on its side or back, and the heat dissipation grille 120 is set in a position corresponding to the heat dissipation side of the water production system.

[0060] like Figures 7-9As shown, the water production system includes an evaporative condenser unit 310, a radiator 320, a compressor 330, and a water collection pan 340. The evaporator and condenser in the evaporative condenser unit 310 are integrated and arranged sequentially along the airflow direction. They are configured so that low-deuterium water vapor first passes through the evaporator to condense into water, and then passes through the condenser to recover the cooling capacity of the air to the refrigerant. The water collection pan 340 is connected below the evaporative condenser unit 310 to collect condensate. The compressor 330 is connected to both the evaporator and condenser, and the radiator 320 is located on the heat dissipation side of the condenser. The evaporator surface fins of the evaporative condenser unit 310 rapidly cool down, creating a large temperature difference with the ambient temperature and falling below the dew point temperature. Low-deuterium water vapor condenses on the evaporator surface fins. The cooled, dehydrated air dissipates heat and cools the refrigerant in the condenser arranged after the evaporator and in the refrigeration pipes, enabling the entire refrigeration system to operate stably for a long time.

[0061] The water purification system 400 includes a first purification filter assembly 410, a booster pump 420, and a manifold 430. The first purification filter assembly 410 is connected to the water collection tray 340 and consists of a first purification filter 411, a second purification filter 412, and a third purification filter 413 connected in series, which are used for three-stage filtration and purification of condensate. The first purification filter 411 is a PP cotton filter element, used to intercept suspended particles and sediment in the condensate; the second purification filter 412 is an activated carbon filter element, used to adsorb residual chlorine, organic matter, discoloration, and odor; the third purification filter 413 is an RO reverse osmosis membrane filter element, used to remove bacteria, viruses, heavy metal ions, and more than 99% of dissolved solids, ultimately producing ultra-low conductivity pure water with a conductivity of less than 1%. This deep purification provides a pure base for subsequent Zisha (purple clay) storage and avoids interference from impurities in the raw water on the release behavior of the Zisha tank. The manifold 430 is connected to the outlet of the first purification filter assembly 410 and is used to collect the condensate after filtration by the first purification filter assembly 410. The inlet of the booster pump 420 is connected to the outlet 110 of the manifold 430, and its outlet 110 is connected to the inlet of the purple clay tank 200. The booster pump 420 is configured to start after the amount of condensate in the manifold 430 reaches a preset water level, and pump the collected condensate into the purple clay tank 200.

[0062] The Zisha (purple clay) jar 200 is installed within the condensation water treatment device 100 and is fixedly positioned by a support ring 130 and a support platform 140. The Zisha jar 200 has a natural double-pore structure, with numerous closed and open pores distributed between its inner and outer walls. In this application, the Zisha jar 200 is configured to perform multiple synergistic functions: utilizing its natural mineral components such as iron, magnesium, calcium, potassium, silicon, and zinc to raise the pH value of the water from 6.5-7.0 to 7.2-7.8, serving as a natural pH adjusting material; utilizing its microporous permeability to maintain a trace amount of air exchange between the water and the container, inhibiting odors and bacterial growth, serving as an odor-suppressing water conditioning container; and utilizing the rich beneficial trace elements in the original Zisha clay to dissolve trace amounts of minerals into the water, serving as a mineral trace element stabilizing material. The Zisha jar 200 has a water outlet at its bottom or lower part, connected to the water outlet 110 on the condensation water treatment device 100 via a food-grade pipe, for users to access the stored water.

[0063] The main control board 500 is electrically connected to the water production system, the water purification system 400, the vaporizing fan 630, the water vapor deuterium sensor 631, and the temperature and humidity sensor 510. The main control board 500 has a pre-set control program that adjusts the speed of the vaporizing fan 630 based on the deuterium content parameter detected by the water vapor deuterium sensor 631, thereby controlling the deuterium content of the low-deuterium water vapor within the range of 100-130 ppm. When the deuterium content is greater than or equal to 130 ppm, the speed of the vaporizing fan 630 is controlled to 1900-2100 rpm; when the deuterium content is less than or equal to 100 ppm, the speed of the vaporizing fan 630 is controlled to 3400-3600 rpm. The main control board 500 also controls the start and stop of the vaporization fan 630 and the water supply pump 623 based on the ambient humidity data detected by the temperature and humidity sensor 510: when the ambient humidity is less than 55%, the vaporization fan 630 and the water supply pump 623 are started; when the ambient humidity is greater than 65%, the vaporization fan 630 and the water supply pump 623 are turned off.

[0064] The condensate water generator 100 has a heat dissipation grille 120 on its side or back, which is positioned corresponding to the radiator 320 to dissipate the heat discharged by the radiator 320 to the outside of the condensate water generator 100. The condensate water generator 100 also has a power port and an operation button, which is electrically connected to the main control board 500. The condensate water generator 100 has a water pipe connector inside, which is connected to the wastewater discharge port of the first purification filter element group 410 or the drain port of the manifold 430, for discharging wastewater generated during the water production and purification process from the condensate water generator 100.

[0065] Secondly, this application also proposes a method for obtaining low-deuterium drinking water by vaporizing and recondensing water, using the water purifier described in the first aspect, comprising the following steps:

[0066] Step 1: The external water source is vaporized into low-deuterium water vapor by the vaporization deuteration device 600, and the deuterium content of the low-deuterium water vapor is controlled within the range of 100-130ppm by adjusting the speed of the vaporization fan 630.

[0067] In step 1, the main control board 500 compares the deuterium content parameter detected by the water vapor deuterium value sensor 631 with a preset low deuterium water vapor deuterium value threshold: when the deuterium content is greater than or equal to 130 ppm, the speed of the vaporizing fan 630 is controlled to 1900-2100 rpm; when the deuterium content is less than or equal to 100 ppm, the speed of the vaporizing fan 630 is controlled to 3400-3600 rpm. The main control board 500 also controls the start and stop of the vaporizing fan 630 and the water supply pump 623 based on the detection value of the temperature and humidity sensor 510: when the ambient humidity is less than 55%, the vaporizing fan 630 and the water supply pump 623 are started; when the ambient humidity is greater than 65%, the vaporizing fan 630 and the water supply pump 623 are turned off.

[0068] Step 2: The low-deuterium water vapor is condensed into liquid low-deuterium water by the condensation water generator 100, and then filtered and purified by the water purification system 400 before being stored in the purple clay tank 200.

[0069] In step 2, the evaporator-condenser unit 310 condenses low-deuterium water vapor into liquid water, the water collection pan 340 collects the condensate, the first purification filter element group 410 performs three-stage filtration and purification on the condensate, the manifold 430 collects the purified pure water, and the booster pump 420 pumps the pure water into the purple clay tank 200 for storage.

[0070] This method achieves deuterium reduction at room temperature with low energy consumption, unlike traditional industrial methods. Traditional methods involve multi-stage distillation requiring high-temperature heating and consuming enormous amounts of energy. This method, however, achieves deuterium reduction through room-temperature vaporization fractionation, upgrading water quality regulation from high-temperature, high-energy consumption to room-temperature, low-energy consumption. It can also provide personalized intelligent adjustments based on differences in the water source substrate in different regions, ensuring that the final effluent consistently approximates the low-deuterium characteristics of natural dew. Simultaneously, the natural preservation function of the Zisha Container 200 further enhances the activity and health value of the water, resulting in effluent that is not only low in deuterium but also rich in balanced minerals, truly achieving a quality restoration similar to natural dew.
