Description

Technical Field

[0001] The invention relates to water treatment technology, and in particular to a dual-function oxygen-supplying hydrogen-rich drinking water cup for high-altitude areas, aiming to improve oxygen supply and drinking water health in low-oxygen environments in high-altitude areas. Background Art

[0002] Due to the low air pressure and thin oxygen in high-altitude areas, local residents and travelers often face the problem of hypoxia or mild hypoxia. In order to cope with this situation, oxygen is usually provided by means of cylinders or carrying oxygen cylinders, but these methods have disadvantages such as inconvenience in carrying, heavy weight, limited space, and high cost of oxygen storage and supply. At the same time, with the growing demand for healthy water, hydrogen-rich water has gradually become popular among consumers because it is believed to have health benefits such as anti-oxidation and enhancing immunity. Therefore, how to provide convenient oxygen supply in high-altitude areas while also achieving the preparation of hydrogen-rich water has become a technical problem that needs to be solved urgently.

[0003] The hydrogen-rich water cups currently on the market do not achieve hydrogen and oxygen separation, and oxygen may be converted into ozone, posing a safety hazard. In addition, the current hydrogen and oxygen production water cups mostly use proton exchange membrane (PEM) electrolysis technology, which has certain problems. For example, the Chinese patent CN209883710U clearly adopts PEM electrolysis technology. The cathode and anode of the electrolyzer are both in a water environment. The produced oxygen contains a large amount of water. It is usually necessary to dry and remove impurities from the produced oxygen to ensure the purity of the oxygen. This treatment process not only makes the equipment structure complex, but also greatly increases the cost, limiting the portability and usability of the equipment. The PEM technology of the Chinese patent CN117964053A uses precious metal electrodes such as platinum, titanium, and iridium, which greatly increases the cost of the cup body. In the hydrogen and oxygen production cup of Chinese patent CN209883710U, hydrogen and oxygen are mixed in water at the same time, which cannot fully utilize the oxygen supply through nasal inhalation and the medical effect of hydrogen; Chinese patents CN218105494U and CN115231660A do not separate electrolyzed water from drinking water when designing the cup body, which poses certain health risks. The product of Chinese patent CN113981471A lacks a reasonable modular design, and does not effectively distinguish the electrolytic cell, power supply and circuit board parts. The working equipment is in a liquid environment for a long time, and the corrosion and aging of equipment components are accelerated, reducing the overall service life of the product.

[0029] 1. Summary of the implementation scheme of the present invention: The dual-function oxygen-absorbing and hydrogen-rich drinking water cup provided by the present invention has main structural components including a cup cover, a cup body, a cup bottom, an electrolysis module, a hydrogen transmission module, a power supply module, an oxygen absorption tube and a drinking water tube; wherein, two through holes are provided on the top of the cup cover, which are used to pass the oxygen absorption tube and the drinking water tube respectively; the cup body includes a first cavity for accommodating water for electrolysis, and a second cavity for accommodating drinking water; an oxygen discharge port and a water supply port are provided at the bottom of the first cavity, the oxygen absorption tube extends downward into the first cavity and the bottom end is connected to the oxygen discharge port, and the drinking water tube extends downward into the second cavity; the first cavity and the second cavity have open ends at the top end of the cup body, and the top end of the cup body and the cup cover are detachably connected, and the first cavity and the second cavity are sealed at the same time; the cup bottom is detachably connected to the bottom end of the cup body, and together with the bottom end of the cup body, a closed third cavity is formed for accommodating the electrolysis module, the hydrogen transmission module and the power supply module The electrolysis module is used for electrolyzing water to produce hydrogen and oxygen, and a cathode water inlet, a cathode gas-liquid outlet, an anode oxygen outlet and an electrode terminal are arranged on its shell; the cathode water inlet is connected to the water supply port at the bottom of the first cavity through a pipeline, and the anode oxygen outlet is connected to the oxygen outlet at the bottom of the first cavity; the hydrogen transport module is used for separating and transporting hydrogen and water, and comprises a gas-liquid separator, an air pump and a nano-gas disk; a gas-liquid inlet, a gas outlet and a water outlet are arranged on the shell of the gas-liquid separator; the gas-liquid inlet is connected to the cathode gas-liquid outlet of the electrolysis module, the gas outlet is connected to the air pump and the nano-gas disk in sequence through a pipeline, and the water outlet is connected to the cathode water inlet of the electrolysis module; the nano-gas disk is arranged at the bottom of the second cavity, and its surface keeps a distance from the bottom end of the drinking water pipe; the power supply module comprises a driving circuit board and an energy storage battery, and the output end of the driving control board is respectively connected to the electrolysis module, the air pump and the switch arranged on the cup body through wires.

[0030] The cup body structure of the present invention is a two-section structure, wherein a first cavity and a second cavity are arranged inside the upper cup body, and a third cavity is arranged inside the lower cup body; the upper cup body and the lower cup body, and the cup bottom and the lower cup body are all detachably connected; wherein the first cavity and the second cavity are nestedly arranged, namely a cylindrical inner cavity and an annular cylindrical outer cavity, and the inner cavity is located at the center of the outer cavity.

[0031] Based on the common design ideas in this field, because there are multiple pipe connection designs in the product, in order to avoid leakage during long-term use and cause short circuit of the power supply line, a partition design can be used to avoid failures as much as possible. For example, during processing and manufacturing, a horizontal or vertical detachable or fixed sealing partition can be used in the third cavity to separate the cavity into two parts; the electrolysis module and the hydrogen transmission module are located on one side of the sealing partition, and the power supply module is located on the other side of the sealing partition.

[0032] Considering that injection molding or die-casting processes have been widely used, in order to simplify the structure and reduce installation operations, the electrolysis module and the gas-liquid separator can be further designed as an integrated structure, and two cavities that accommodate the electrolysis module and the gas-liquid separator are formed inside the common shell with a partition; the gas-liquid inlet of the gas-liquid separator is directly connected to the cathode gas-liquid outlet of the electrolysis module through the channel on the partition; the water outlet of the gas-liquid separator is directly connected to the cathode water inlet of the electrolysis module through the channel on the partition; the water supply port at the bottom of the first cavity is connected to the cathode side of the electrolysis module through a pipeline. Although the mold processing cost of this design scheme increases, it can reduce the number of connecting parts and reduce the risk of leakage. At the same time, it can also enhance the strength of the components and reduce the installation workload.

[0033] The multiple detachable movable connections in the water cup can be any of the following: (1) mutually matching external threads and internal threads are provided on adjacent parts to achieve connection by screwing; (2) one side of the adjacent parts is connected by a hinge structure, and a mutually matching clip structure is provided on the other side to achieve connection by snap-fit. Both connection methods are common designs for water cup products.

[0034] Since hydrogen has a low solubility in water, in order to avoid safety hazards caused by excessive accumulation of hydrogen, a pressure relief valve is provided on the cup lid, and the pressure relief valve corresponds to the opening end of the second cavity; when the gas pressure inside the second cavity reaches the design threshold of the pressure relief valve, it can be automatically discharged.

[0035] The following are other optional solutions for the design or processing of the water cup product of the present invention: A sealing gasket is provided in the cup cover, and the first cavity and the second cavity are sealed simultaneously when the cup cover and the cup body are closed; this design can prevent the internal gas and liquid from flowing out, and can also prevent the liquid or gas in the first cavity and the second cavity from mixing with each other.

[0036] The oxygen outlet at the bottom of the first cavity has an upwardly protruding connection port, and the bottom end of the oxygen absorption pipe is tightly sleeved on the connection port for installation. Similarly, the water supply port at the bottom of the first cavity has a downwardly protruding connection port, and the pipeline connected to the cathode water inlet of the electrolysis module is tightly sleeved on the connection port.

[0037] The oxygen inhalation tube can be optionally of a one-piece integral structure or a two-piece detachable structure; the two-piece detachable structure can facilitate the replacement of the upper tube body, and can be easily replaced after long-term use or when multiple people use it at the same time to ensure hygiene.

[0038] There are one or more openings on the wall of the oxygen inhalation tube that is exposed to the cup cover. The purpose of the openings is to bring in an appropriate amount of air while inhaling oxygen to avoid discomfort caused by inhaling too much pure oxygen. The user can use his fingers to adjust the mixing ratio of air and oxygen by pressing the opening or pressing the opening. The opening method can be to directly punch holes on the tube wall, or to Figure 1 As shown in , an inclined branch pipe with an open end facing downward is arranged on the pipe wall of the cup cover exposed portion.

[0039] The air pump includes an air inlet and an air outlet. A micro air pump with an exhaust volume between 0.05 and 1 L / min can be selected to increase the pressure and flow rate of hydrogen discharge. The specific model is determined according to the hydrogen production of the electrolysis module. The nano gas disk includes a nano gas stone and a shell. The shell is embedded in the bottom of the second chamber, and the nano gas disk is embedded in the upper part of the shell. An air inlet that runs through the bottom of the second chamber is provided on the bottom side of the shell, and the outlet end of the air pump is connected to the air inlet through a pipeline. When hydrogen flows through the nano gas stone, fine bubbles can be formed to increase the solubility of hydrogen in water. In actual use, it is not necessary to continuously start the air pump. The driver circuit board can be used to set the interval and duration of the timed start.

[0040] The internal structure of the gas-liquid separator can be any of the following: a floating ball type gas-water separator, a fixed waterproof breathable membrane, or a waterproof breathable valve. By selecting a suitable type of micro air pump, combined with the capacity of the pipeline and the gas-liquid separator, the hydrogen produced by the electrolysis module can be discharged smoothly.

[0041] The electrolysis module adopts any of the following structural forms: anion exchange membrane (AEM) electrolyzer, proton exchange membrane (PEM) electrolyzer, or weak alkaline electrolyzer (the pH value of alkaline electrolyzed water is between 7.0 and 10.0). The present invention preferably uses an AEM electrolyzer, in which the inside of the electrolyzer is divided into a cathode side and an anode side by a diaphragm; during use, the cathode side is filled with water and produces hydrogen, while the anode side produces oxygen and a small amount of water. Based on this principle, the gas-liquid mixture discharged from the cathode side needs to be separated from the gas and liquid. Since human breathing itself also requires a small amount of water to moisturize the lungs, the oxygen on the anode side does not need to be separated from the water. If water accumulation occurs after long-term use, it is only necessary to dump the accumulated water through the oxygen supply tube. The AEM electrolyzer can be equipped with different capacities and powers according to the actual product volume to meet the needs of different users.

[0042] The energy storage battery can be a rechargeable lithium battery, a sodium ion battery, a zinc ion battery, or a zinc-air battery, which is used to provide the required electrical energy for the electrolysis module and the water pump. The driving circuit board is used to control the operation of each electrical device to ensure the normal operation of the water cup. The switch can be a membrane button, a mechanical switch, an inductive touch switch, or a voice-controlled switch. The start-up operation of the electrolysis module can be performed through the action of the switch, so that it can be turned on and used immediately. The electrode terminal of the electrolysis module can be selected as a welded terminal, a plug-in terminal, or a rotary terminal contact, depending on the product design requirements. The content of circuit connection and control belongs to the commonly used public technology, and the present invention will not repeat it.

[0043] The cup cover, cup body and cup bottom can be made of food-grade stainless steel plates, and the first cavity, the second cavity and the third cavity are covered by the shell. Stainless steel has better corrosion resistance, oxidation resistance and longer service life, and can also provide better appearance texture.

[0044] When in use, the oxygen generated by the electrolysis module is discharged through the oxygen inhalation tube, and the user inhales the oxygen to meet the supplementation needs. The hydrogen-rich water is discharged through the drinking water tube to meet the user's water intake needs.

[0045] Compared with the existing hydrogen or oxygen drinking cup products, the present invention innovatively uses AEM (anion exchange membrane) water electrolysis technology in the hydrogen-rich drinking cup product. Compared with PEM electrolysis technology, AEM water electrolysis technology is a relatively low-cost and efficient water electrolysis method. AEM technology uses an anion exchange membrane to separate the two electrode chambers of the electrolyzer, allowing hydroxide ions (OH - ) migrates from the cathode to the anode, producing hydrogen and oxygen at the two electrodes respectively. Compared with traditional PEM technology, the advantage of AEM electrolysis technology is that it can avoid drying and removing impurities from oxygen, simplifying the separation process, and the anode does not require special requirements for the water environment, reducing the complexity of the system. In addition, the AEM hydrogen production electrode only requires a nickel-based transition metal electrode, which greatly reduces the material cost. Therefore, the use of AEM technology in hydrogen and oxygen production cups can effectively separate and dry oxygen, and achieve low-cost drinking hydrogen and oxygen inhalation. This product can meet the needs of use in specific scenarios at the same time, and is therefore more adaptable to application needs in special scenarios in reality, such as daily life in plateau areas, business trips and travel, or health care for middle-aged and elderly people.

[0046] 2. Embodiment 1 Reference Figure 1The dual-function oxygen-supplying hydrogen-rich drinking cup in this embodiment includes a cup cover 1, a cup body 2, a cup bottom 23, a hydrogen transmission module 3, an electrolysis module 4, a straw 5 and a power supply module 6. A central circular hole 11, an edge circular hole 12 and a pressure relief valve 13 are provided on the top surface of the cup cover 1. The pressure relief valve 13 uses a spring-type automatic pressure relief valve. When the pressure in the inner cup cavity is higher than the specified pressure value, the pressure valve will automatically release gas to reduce the pressure in the cup. The cup cover 1 is connected to the cup body 2 by threads for sealing. The outer shell of the cup cover 1, the cup body 2 and the cup bottom 23 is made of food-grade stainless steel, which has good corrosion resistance and oxidation resistance, can effectively extend the service life of the water cup, and provide a better appearance texture. The cup body 2 is divided into two parts: a double-layer cup body 21 (i.e., the upper cup body) and a single-layer cup body 22 (i.e., the lower cup body). The former has a closed bottom end to form two inner cavities (a first cavity and a second cavity) for holding liquid, and the latter forms an inner cavity (i.e., a third cavity) with the cup bottom 23 for placing the gas-liquid separator 31 and the air pump 32 in the hydrogen transport module 3, as well as the electrolysis module 4 and the power supply module 6. The double-layer cup body 21 and the single-layer cup body 22, and the single-layer cup body 22 and the cup bottom 23 are connected by threads, respectively.

[0047] Reference Figure 2 The shell of the double-layer cup body 21 is provided with an annular outer cup cavity 211 (i.e., the first cavity) and a cylindrical inner cup cavity 212 (i.e., the second cavity), which are coaxially nested. The outer cup cavity 211 contains water for electrolysis, and two hollow cylindrical openings are provided at the bottom, namely, a water supply port 2111 and an oxygen exhaust port 2112. The inner cup cavity 212 contains drinking water, and an inner cup cavity air inlet 2121 is provided at the bottom of the cavity, which is used to connect the nano gas disk 33 and the air inlet pipe 331.

[0048] The hydrogen transport module 3 includes a gas-liquid separator 31, an air pump 32, and a nano gas disc 33. The shell of the gas-liquid separator 31 is provided with a gas-liquid inlet 311, a water outlet 312, and a gas-liquid separator air outlet 313. The air pump 32 includes an air pump air inlet 321 and an air pump air outlet 322. The gas-liquid separator air outlet 313 of the gas-liquid separator 31 is connected to the air pump air inlet 321 of the air pump 32 through a food-grade plastic hose (the same below). The nano gas disc 33 includes a nano gas stone 332 and a shell 333. The nano gas stone 332 is embedded in the shell 333, and the shell 333 is seated at the bottom of the inner cup cavity 212. An inner cup cavity air inlet 2121 is provided at the bottom of the inner cup cavity 212, one end of the air inlet pipe 331 is connected to the inner cup cavity air inlet 2121, and the other end is connected to the air pump outlet 322 of the air pump 32. The hydrogen discharged from the gas-liquid separator 31 is sent to the nano-gas stone 332 through the air pump 32, and the hydrogen is dissolved in the water in the form of nano-microbubbles on the surface of the nano-gas stone 332.

[0049] The electrolysis module 4 adopts an anion exchange membrane electrolyzer (AEM), and its shell is provided with a cathode water inlet 411, a cathode gas-liquid outlet 412, and an anode oxygen outlet 413. The cathode water inlet 411 is connected to the water supply port 2111 and the water outlet 312 respectively through a Y-shaped tube, the cathode gas-liquid outlet 412 is connected to the gas-liquid inlet 311, and the anode oxygen outlet 413 is connected to the oxygen outlet 2112.

[0050] The straw 5 includes an oxygen inhalation tube 51 and a drinking water tube 52. The oxygen inhalation tube 51 is divided into a lower tube section 511 and an upper tube section 512. The lower tube section 511 passes through the edge circular hole 12 and is connected to the oxygen outlet 2112 at the bottom of the outer cup cavity 211. An oblique branch with an open end facing downward is provided on the tube wall of the upper tube section 512, which is used to mix oxygen with air and then transport it to the user end. The drinking water tube 52 passes through the central circular hole 11 and approaches the bottom of the inner cup cavity 212 to transport hydrogen-rich water to the user.

[0051] like Figure 3 As shown, the power supply module 6 includes a lithium battery 61 and a driving circuit board 62. The lithium battery 61 provides the required electrical energy for the electrolysis module 4 and the air pump 32, and the driving circuit board 62 is used to control the working state of the electrical components to ensure coordinated operation and keep the water cup working stably.

[0052] When in use, the user adds an appropriate amount of water into the two cup chambers of the double-layer cup body 21. After the power supply module 6 is started by pressing the button on the cup body 2, the electrolysis module 4 starts to operate. Figure 4 As shown, during the electrolysis process, water in the outer cup cavity 211 enters the electrolysis module 4 through the cathode water inlet. Under the action of the external current, water molecules undergo a reduction reaction at the cathode to generate hydrogen and hydroxide ions (OH - ); the hydroxide ions (OH - ) moves through the anion exchange membrane to the anode under the action of an external electric field, and loses electrons at the anode to generate oxygen. The anion exchange membrane (AEM) only allows hydroxide ions (OH - ) moves from the cathode to the anode to maintain charge balance, thereby promoting the continuation of the electrolysis reaction and achieving the process of efficiently electrolyzing water into hydrogen and oxygen.

[0053] The chemical reaction ion equations at the cathode and anode are as follows: Cathode: 4H2O(l) + 4e - → 2H2(g) + 4OH - Anode: 4OH - → O2(g) + 2H2O(l) + 4e - The water mixed with hydrogen flows out from the cathode gas-liquid outlet 412 and enters the gas-liquid separator 31. After the gas-liquid separation, the hydrogen is pressurized by the air pump 32, and then generates micro-nano bubbles through the nano gas stone 332 in the nano gas disk 33, which is efficiently dissolved in the drinking water to generate hydrogen-rich water; the separated water flows through the conduit and enters the cathode water inlet 411 on the cathode side. At the same time, oxygen is transported to the oxygen absorption pipe 51 through the anode oxygen outlet 413 in the electrolysis module 4 for use by users.

[0054] The AEM electrolysis technology used in this embodiment simplifies the hydrogen and oxygen separation process, avoids the drying and impurity removal requirements for oxygen, reduces production costs, and improves the economy of the system. Through the synergistic effect of the gas-liquid separator and the nano gas disk, hydrogen can be effectively dissolved in water to generate hydrogen-rich water (mass concentration ≥ 1000ppb), which has strong antioxidant and health benefits.

[0055] Embodiment 2 This embodiment is based on a high altitude area with an altitude of about 2000m, and describes the oxygen supply situation of the product of the present invention in an actual application scenario.

[0056] Product specifications: The external volume of a water cup that usually meets the handheld requirements is about 500-1500ml. Under the condition that the internal parts installation requirements are met, the effective area of ​​the anion exchange membrane (AEM) electrolyzer is A = 25cm 2 , current density j = 500 mA / cm 2 Conventional lithium batteries with a current of more than 5000 mA can ensure that the electrolytic cell can operate stably for at least 1 hour.

[0057] according to I = j × A , we can get: I = 500 mA / cm 2 × 25 cm 2 = 12500 mA = 12.5 A According to Faraday's law and combined with the anode electrode reaction formula, the number of moles of oxygen can be obtained n for: ; The volume of oxygen at standard conditions is V for: V = 2.0 × 10 -3 mol / min × 22.4L / mol ≈ 0.045 L / min That is, the product of the present invention can generate 0.045 L oxygen.

[0058] According to the "Tibet Autonomous Region Civil Oxygen Supply Engineering Design Standard" DBJ540004-2018, at an altitude of 2000 meters, the oxygen partial pressure in the air is 124.6 mmHg, and the equivalent concentration of oxygen is 16.4%. Compared with sea level, the oxygen concentration is about 80% of the sea level concentration, so 20% of oxygen needs to be supplemented to meet the demand. According to the standards certified by the American College of Sports Medicine, when the human body is at rest, the human body consumes 3.5mL of oxygen per kilogram of body weight per minute under normal metabolism. Assuming that the average weight of the user is about 60kg, about 0.21L of oxygen needs to be provided to the user per minute. At a high altitude of 2000 meters, due to the low oxygen concentration in the air, an additional 0.042 NL / min of oxygen needs to be supplemented to maintain normal metabolism.

[0059] Therefore, the oxygen supply equipment of this embodiment can stably provide sufficient oxygen supply according to the above calculation to meet the oxygen needs of users in areas with an altitude of 2000 meters, ensuring that the equipment can operate normally under such environmental conditions and effectively provide oxygen to achieve the expected oxygen supply effect.

[0060] The above is only a preferred specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any modification or alternative that can be easily thought of by any technician with relevant knowledge in the technical field based on the technical content disclosed in the present invention should be included in the protection scope of the present invention.
