The following detailed description of the preferred embodiments of the utility model, however, the utility model is capable of other embodiments in addition to those detailed.

The existing drinking water purifying equipment has the following defects: first, a water supply network that relies on a liquid water source and supplies the liquid water source is constructed to provide potable water. Firstly, fresh water resources available for human use are becoming scarce due to recent climate change, population soaring, serious water pollution and other problems. Secondly, in towns, the provision of liquid water (tap water) is a prerequisite for the large and complex infrastructure of the town water supply system, i.e. a series of facilities from the source, to the water works, to the water supply network, and finally to the tap water faucet from the secondary water supply system within the building. The traditional urban water supply system has some technical defects for a long time, such as the problem that the water quality of effluent of a water supply plant can not reach the standard stably for a long time or disinfection by-product residues exist. The secondary pollution problem of tap water in town pipe networks comprises that rust and particles enter the tap water due to corrosion of pipes, the tap water pipe bursts, and pollutants caused by leakage flow into the tap water pipe. The secondary water supply system of the building also has the problems of water storage tank and pipeline bacterial pollution and the like. The technical disadvantages listed above with these existing urban water supply systems eventually lead to two problems for the user's tap water, unstable tap water supply, and poor or even unsafe tap water quality. These problems are exacerbated in less developed or water-scarce areas. Secondly, the existing water purifying equipment needs to rely on a power grid or other additional power supply equipment to provide electric power, cannot be used in severe environments without any power supply facilities, and most of the existing water purifying equipment needs to be provided with or connected with a water source power supply, so that the mobility is poor.

Specifically, the air filter 8 is disposed at an air inlet of the equipment enclosure 7, and under the action of an induced air fan 13 disposed at the air outlet, air with a certain humidity passes through the air filter 8 and enters the equipment enclosure 7. The air filter 8 is used to remove contaminants in the air, such as suspended particulate matter (PM2.5) less than 2.5 microns, and the like. Through air filter 8 at the air intake installation of extraction air, effectively obstructed dust, virus etc. that exist in the air and got into the condensate water, protected follow-up water treatment unit not disturbed by large granule impurity, more guaranteed the quality of follow-up product water. The air filter 8 herein includes, but is not limited to, a fiberglass filter, a polyester filter, an electrostatic filter, and a high efficiency particulate trap (HEPA) filter, or a combination of any at least two of the foregoing.

The process of converting water vapor in air into liquid water in the double-water-source double-power-supply direct drinking machine provided by the embodiment of the utility model utilizes a compression type refrigeration technology, and the main equipment comprises an evaporator 9, a condenser 10, a compressor 11, a refrigerant and other parts. This unit produces liquid water by keeping the evaporator cold, condensing water vapor entering the air of the device.

Specifically, the evaporator 9 is close to the air filter 8, the condensate tank 12 is arranged below the evaporator 9, when the air purified by the air filter 8 passes through the low-temperature surface of the evaporator 9, the temperature of the water vapor in the air is reduced to the dew point temperature, the water vapor is condensed into liquid water drops, the liquid water drops accumulated continuously are collected into a flow, and the flow is dropped into the condensate tank 12 right below the evaporator 9 under the action of gravity for temporary storage. The air with reduced humidity and temperature continues to flow to the condenser 10 under the continuous action of the induced draft fan 13, the surface temperature of the condenser 10 is high, the air is heated and returns to the temperature close to the temperature of the incoming air, and the dried air is finally discharged out of the equipment housing 7 by the induced draft fan 13.

In addition, the condensed water tank 12 is also connected with a spare water source interface 15, and if a liquid water source is adopted, the liquid water directly enters the condensed water tank 12 from the spare water source interface 15 for temporary storage.

The evaporator 9 and the condenser 10 are connected to a compressor 11, respectively. The reason why the evaporator 9 is kept at a low temperature for a long time is a compression refrigeration system composed of a compressor 11, the evaporator 9, a condenser 10, and a refrigerant (such as freon) circulating in a closed loop in a tube. The basic principle of the compression refrigeration system is as follows: the high-pressure refrigerant vapor discharged from the compressor 11 is condensed into a refrigerant liquid by heat release from the condenser 10. Then, the refrigerant liquid is throttled by a throttle valve (expansion valve), the pressure and the temperature are simultaneously reduced, the refrigerant liquid enters the evaporator 9, the temperature of the pipe wall of the condensation pipe of the evaporator 9 is reduced, the heat in the air contacting with the evaporator 9 is absorbed, so that the humid air is cooled, and the refrigerant liquid is heated and evaporated into refrigerant vapor. The refrigerant vapor then enters the compressor 11 for further compression, and is circulated, thereby maintaining the evaporator 9 at a low temperature.

The condensate tank 12 is connected with a self-priming water inlet pump 14, the self-priming water inlet pump 14 is connected with a downstream water purification unit, and the water purification unit is arranged below the condensate tank 12. As the condensed water stored in the condensed water tank 12 increases, the condensed water is pumped into the water purification unit by the self-priming intake pump 14. The self-suction water inlet pump 14 can not only stably suck out water in the condensed water tank 12, but also provide a certain positive pressure to ensure the normal operation of each subsequent filtering unit. In addition, when the water supply system operates by using a liquid water source rather than a gaseous water source, the self-suction water inlet pump 14 determines that the water supply system not only can be connected with a tap water faucet with a hydraulic household and commercial scene, but also can be used in areas with water supply network infrastructure soundness, and can self-suction non-pressure water sources such as water cylinders, well water, river water and the like into a water quality purification unit to generate clean and safe drinking water.

The water purification unit comprises a front-mounted filtering device and a nanofiltration filter element 18 which are sequentially connected, and the front-mounted filtering device comprises a PP cotton filter element 16 (namely a polypropylene melt-blown filter element) and an active carbon filter element 17 which are sequentially connected. The condensed water firstly enters the PP cotton filter element 16 and the active carbon filter element 17 in sequence, a small amount of particulate matters, turbid matters and other particulate matters possibly existing in the condensed water are filtered and separated, and meanwhile, other organic pollutants, heterochrosis, peculiar smell and the like caused by the organic pollutants are also adsorbed and removed, so that the effects of pretreatment and protection of the nanofiltration filter element are achieved. Wherein, the PP cotton filter element 16 includes but is not limited to a 10 μm PP cotton filter element, a 5 μm PP cotton filter element, and a 1 μm PP cotton filter element; the activated carbon filter element 17 includes, but is not limited to, a sintered activated carbon filter element and a compressed activated carbon filter element, and is determined according to the quality and quantity of the treated water. By adopting the pre-filtering device containing PP cotton and activated carbon, the pre-filtering device can play a role in pre-treating and protecting the nanofiltration filter element 18, wherein the type and specification of the filter element of the pre-filtering device can be determined according to the water quality and the water quantity of water to be treated, the operation is flexible, and the replacement is convenient.

The effluent of the activated carbon filter element 17 enters the nanofiltration filter element 18, and the membrane aperture of the nanofiltration filter element 18 is as small as 1nm, so that the method is an efficient water purification method and is often used for the production of direct drinking water. The nanofiltration filter element 18 in this embodiment can filter and retain most of the pollutants, hardness, chromaticity, etc., including organic pollutants such as pesticides and some Volatile Organic Compounds (VOCs), bacteria, divalent ions (sulfate ions, nitrate ions, divalent metal ions, etc., which are common in air), etc., which are soluble in water, and only monovalent ions (potassium, sodium, chlorine, etc.) are selectively retained. The water passing through the nanofiltration filter element 18 is clean and stable, so that the produced water meets the demand of direct drinking.

Compared with the common ultrafiltration or microfiltration filter core of other water purification equipment in the market, the nanofiltration filter core 18 has smaller membrane aperture which can reach 1 nanometer, and monovalent ions are removed after the filtration of the membrane with the tiny apertureSuch as chlorine, sodium, potassium, etc., and water molecules, and other most substances in water such as divalent ions (including NO carried in air-produced water)_x、SO_x) And the aerogenic bacteria, viruses, particles, organic matters and the like can be efficiently removed. The use of the nanofiltration filter element 18 ensures the safety and high cleanliness of the prepared produced water, and the water quality is superior to that of common water quality purification equipment using ultrafiltration or microfiltration in the market.

Finally, since certain concentrations of calcium, magnesium ions and other trace elements in drinking water are beneficial to human body, the World Health Organization (WHO) recommends that the hardness value in drinking water be 170mg/L (i.e., the sum of the concentrations of calcium and magnesium ions). In order to ensure the safety and cleanness of produced water and balance the health of drinking water, the water purification unit of the embodiment is also provided with the mineralization filter element 19 connected with the nanofiltration filter element 18, when purified water flows through the mineralization filter element 19, mineral fillers such as natural calcite, medical stone and artificially synthesized mineralization balls slowly release calcium ions, magnesium ions and other trace mineral elements with certain concentration, so that the aim of improving the concentration of beneficial mineral ions in the produced water is fulfilled.

In order to ensure better pollutant removal performance of the existing water purification equipment, reverse osmosis or nanofiltration technology is adopted to filter and purify water, and although the reverse osmosis or nanofiltration technology can effectively isolate most pollutants in water, most minerals and trace elements, such as calcium, magnesium and the like, which are necessary for human bodies in water can be removed at the same time. The long-term drinking of water with low mineral content is not beneficial to the absorption of nutrient elements from water by human bodies and the health of human bodies, and simultaneously can cause the problem of poor drinking taste. Therefore, the existing water purifying equipment is difficult to balance the drinking water safety and the drinking water health. In order to ensure that the drinking water is safe and beneficial to human health, the embodiment of the utility model adds the mineralization filter element 19 which can slowly release various mineral substances such as calcium, magnesium and the like into the water after the nanofiltration filter element 18 in the water purification unit, and the mineralization filter element 19 is matched with the nanofiltration filter element 18, so that the mineralization filter element can ensure that various pollutants are efficiently removed, simultaneously ensure that the water still contains proper amount of mineral substances and trace elements necessary for human body, and improve the health degree of the drinking water.

The water purification unit is connected and is directly drunk water tank 20, and directly drinks water tank 20 and sets up in the water purification unit below, accomplishes the direct drinking water that purifies and add the ore deposit and is stored in directly drinking water tank 20. Because the direct drinking water tank is soaked by water for a long time, bacteria can be bred on the inner wall of the water tank inevitably, a bacterial film is formed, and the water quality is influenced. For further keeping the clean of drinking water and preventing the long bacterial membrane of direct drinking water tank 20 inner wall, the dual water source dual power direct drinking machine of this embodiment has added ultraviolet lamp sterilizing equipment 21 in direct drinking water tank 20, and the bacterium of aquatic can effectively be killed to the ultraviolet light, lets water tank inner wall and pipeline inner wall keep clean for a long time, keeps the last drinking water safety gate before the drinking water gets into the human body.

The direct drinking water tank 20 is also equipped with a water quantity sensing device for automatically sensing the water quantity and automatically keeping the water quantity within a certain range for the user to use at any time. Direct drinking water outlet valve 23 and direct drinking water outlet pump 22 are connected to direct drinking water tank 20, and when the user used, only need open direct drinking water outlet valve 23, direct drinking water outlet pump 22 will start sending out direct drinking water.

The embodiment of the utility model provides a double-water-source double-power-supply direct drinking machine which utilizes green and renewable energy source solar energy to provide electric power, utilizes vapor in air to condense to generate liquid water, and finally generates clean and healthy drinking water through an advanced water quality purification module. The dual-water-source dual-power direct drinking machine disclosed by the embodiment of the utility model can provide drinking water in traditional scenes, such as scenes in cities, towns, household, commercial, industrial and the like, and can also be used in special scenes in which drinking water is difficult to obtain, such as vehicle-mounted scenes, ship-mounted scenes, field camps without water supply and power supply, emergency disaster relief, military camp, forest parks and the like, so that the problem that the conventional drinking water purifying equipment cannot provide drinking water under the condition of no liquid water source or no power grid is solved.
