DETAILED DESCRIPTION OF EMBODIMENTS

[0056] To render the technical solutions of the present disclosure clearer, the disclosure will be described in detail below with reference to the drawings and embodiments. It is apparent that the embodiments provided below are merely some embodiments of the disclosure and are not intended to limit the disclosure.

[0057] As shown in FIGS. 1-3, an apparatus for preparing hydrogen water includes a pressure tank 1 made of stainless steel, an membrane-type liner 2 arranged in the pressure tank 1 and a pressure tank cover 3 made of stainless steel. An interior of the membrane-type liner forms a first cavity 5, and a second cavity 6 is formed between an inner wall of the pressure tank 1 and an outer wall of the membrane-type liner 2. The membrane-type liner 2 is made of an organic silicone-rubber composite. The pressure tank cover 3 is provided with a first water port 4 for feeding and discharge of water. A bottom of the pressure tank 1 is provided with an air hole 7. The pressure tank 1 is provided with a fastener 8, and the pressure tank 1 is sealedly connected with the pressure tank cover 3 through the fastener 8, so that the pressure tank cover 3 can be disassembled quickly, facilitating the cleaning and disinfection of the membrane-type liner 2. An upper convex ring 10 is arranged on an upper surface of an outer wall of an opening of the membrane-type liner 2, and a surface of the pressure tank cover 3 contacting with the upper convex ring 10 is provided with an upper annular groove 12 matching with the upper convex ring 10. A lower convex ring 11 is arranged on a lower surface of the outer wall of the opening of the membrane-type liner 2, which matches with a lower annular groove 13 arranged on the opening of the pressure tank 1, such that the pressure tank cover 3 is just arranged above the upper convex ring 10 for sealed connection. The first water port 4 of the pressure tank cover 3 is provided with a quick-plug assembly 9 made of stainless steel, including a female plug 91 and a male plug 92, where the female plug 91 is sealedly connected with the male plug 92 by plugging, which can isolate the air, so that the hydrogen water will not be exposed to the air during the process of inflow and outflow, preventing secondary pollution and keeping the stored hydrogen water in a fresh state for a long time. Furthermore, the quick-plug assembly 9 can be quickly connected with various drinking water equipment or water supply equipment to realize the integration of utilization, storage and preparation of hydrogen water. In an embodiment shown in FIG. 4, a threaded joint 101 is provided at the first water port 4, where one end of the threaded joint 101 is sealedly connected with the first water port 4 on the pressure tank cover 3, and the other end of the threaded joint 101 is sealedly connected with various drinking water equipment or water supplying equipment by screwing.

[0058] The purified water is injected into the first cavity 5 (namely an interior of the membrane-type liner 2 made of silicone rubber with a permeability of 289 barrer; 1 barrer=10.sup.−10.Math.cm.sup.3 (STP) cm.Math.s.sup.−1.Math.cm.sup.−2.Math.cm Hg.sup.−1) through the first water port 4.

[0059] Since the polymer composite has good elasticity, the pore structure thereon can be stretched by increasing the pressure. Ultra pure hydrogen gas (purity: 99.999%) with a pressure of 0.3 MPa is fed into the second cavity 6 through the air hole 7 for storage (for about 3-month use; the hydrogen gas can be repeatedly fed when it is insufficient). The hydrogen gas stored in the second cavity 6 can be diffused into the membrane-type liner 2 for 2 hours, and then gradually penetrates into the water in the first cavity 5. Meanwhile, the pressure tank 1 is placed on an ultrasonic oscillator to accelerate the diffusion of hydrogen molecules and enable the hydrogen molecules and water to be fully mixed. Then the pressure tank 1 is subjected to standing for 0.5 h to form a stable hydrogen-in-water structure to obtain hydrogen water with a hydrogen molecule concentration of 2.3 ppm. When the first water port 4 is opened, the hydrogen water in the first cavity 5 is driven by the gas pressure in the second cavity 6 to be automatically discharged.

Embodiment 2

[0060] An apparatus and a method for preparing hydrogen water are provided herein. The apparatus includes a pressure tank 1 made of stainless steel, a membrane-type liner 2 arranged in the pressure tank 1 and a pressure tank cover 3 made of stainless steel. An interior of the membrane-type liner forms a first cavity 5, and a second cavity 6 is formed between an inner wall of the pressure tank 1 and an outer wall of the membrane-type liner 2. The membrane-type liner 2 is made of a polysulfone composite. The pressure tank cover 3 is provided with a first water port 4. A bottom of the pressure tank 1 is provided with an air hole 7. The pressure tank 1 is sealedly connected with the pressure tank cover 3 through threaded connection, so that the pressure tank cover 3 can be disassembled quickly, facilitating the cleaning and disinfection of the membrane-type liner 2. An upper convex ring 10 is arranged on an upper surface of the outer wall of an opening of the membrane-type liner 2, and a surface of the pressure tank cover 3 contacting with the upper convex ring 10 is provided with an upper annular groove 12 matching with the upper convex ring 10. A lower convex ring 11 is arranged on a lower surface of the outer wall of the opening of the membrane-type liner 2, which matches with a lower annular groove 13 arranged on the opening of the pressure tank 1, such that the pressure tank cover 3 is just arranged above the upper convex ring 10 for sealed connection. The first water port 4 of the pressure tank cover 4 is provided with a quick-plug assembly 9 made of stainless steel, including a female plug 91 and a male plug 92, where the female plug 91 is sealedly connected with the male plug 92 by plugging, which can isolate the air, so that the hydrogen water will not be exposed to the air during the process of inflow and outflow, preventing secondary pollution, and keeping the stored hydrogen water in a fresh state for a long time. Furthermore, the quick-plug assembly 9 can be quickly connected with various drinking water equipment or water supply equipment to realize the integration of utilization, storage and preparation of hydrogen water.

[0061] The purified water is injected into the first cavity 5 (namely an interior of the membrane-type liner 2 made of the polysulfone composite with a permeability of 51.5 barrer) through the first water port 4. Since the polymer composite has good elasticity, the pore structure thereof can be stretched by increasing the pressure. Ultra pure hydrogen (purity: 99.999%) with a pressure of 1.0 MPa is fed into the second cavity 6 through the air hole 7 for storage (for about 3-month use; the hydrogen gas can be repeatedly fed when it is insufficient). The hydrogen gas stored in the second cavity 6 can be diffused into the membrane-type liner 2 for 4 hours, and then gradually penetrates into the water in the first cavity 5. Meanwhile, the pressure tank 1 is placed on an ultrasonic oscillator to accelerate the diffusion of hydrogen molecules and enable the hydrogen molecules and water to be fully mixed. Then the pressure tank 1 is subjected to standing for 0.5 h to form a stable hydrogen-in-water structure to produce hydrogen water with a hydrogen molecule concentration of 3.0 ppm, and then the pressure in the second cavity 6 of the pressure tank 1 is adjusted to 0.1-0.35 MPa in a static state for normal use of the hydrogen water. When the first water port 4 is opened, the hydrogen water in the first cavity 5 is driven by the gas pressure in the second cavity 6 to be automatically discharged.

Embodiment 3

[0062] As shown in FIGS. 1-5, an apparatus and a method for preparing hydrogen water are provided. The apparatus includes a pressure tank 1 made of stainless steel, a membrane-type liner 2, a pressure tank cover 3 made of stainless steel and a multifunctional water processor 25, where the membrane-type liner 2 and the multifunctional water processor 25 are detachably arranged in the pressure tank 1, and the pressure tank cover 3 is detachably arranged on the pressure tank 1. An interior of the membrane-type liner 2 forms a first cavity 5, and a second cavity 6 is formed between an inner wall of the pressure tank 1 and an outer wall of the membrane-type liner 2. The membrane-type liner 2 is made of silica gel. The pressure tank cover 3 is provided with a first water port 4, and a bottom of the pressure tank 1 is provided with an air hole 7. The pressure tank 1 is sealedly connected with the pressure tank cover 3 through the threaded connection, so that the pressure tank cover 3 can be disassembled quickly, facilitating the cleaning and disinfection of the membrane-type liner 2. An upper convex ring 10 is arranged on an upper surface of an outer wall of an opening of the membrane-type liner 2, and a surface of the pressure tank cover 3 contacting with the upper convex ring 10 is provided with an upper annular groove 12 matching with the upper convex ring 10. A lower convex ring 11 is arranged on a low surface of the outer wall of the opening of the membrane-type liner 2, which matches with a lower annular groove 13 arranged on the opening of the pressure tank 1, such that the pressure tank cover 3 is just arranged above the upper convex ring 10 for sealed connection. The first water port 4 of the pressure tank cover 3 is provided with a quick-plug assembly 9 made of stainless steel, including a female plug 91 and a male plug 92, where the female plug 91 is sealedly connected with the male plug 92 by plugging, which can isolate the air, so that the hydrogen water will not be exposed to the air during the process of inflow and outflow, preventing secondary pollution, and keeping the stored hydrogen water in a fresh state for a long time. Furthermore, the quick-plug assembly 9 can be quickly connected with various drinking water equipment or water supply equipment to realize the integration of utilization, storage and preparation of hydrogen water. In an embodiment shown in FIG. 4, a threaded joint 101 is provided at the first water port 4, where one end of the threaded joint 101 is sealedly connected with the first water port 4 on the pressure tank cover 3, and the other end of the threaded joint 101 is sealedly connected with various drinking water equipment or water supplying equipment by screwing.

[0063] The purified water is injected to the multifunctional water processor 25 through the first water port 4, and then enters the first cavity 5 (namely an interior of the membrane-type liner 2 made of silica gel) for storage. The multifunctional water processor 25 includes a first chamber and a second chamber arranged in series. A first functional core 19 arranged in the first chamber is composed of activated carbon fiber and a non-woven material, and a second functional core 20 arranged in the second chamber is composed of two sets of detachable magnetic materials. The above-mentioned two chambers are sealedly connected by threaded connection, and are in communication with each other. A second water port 15 on the multifunctional water processor 25 and the water inlet/outlet 4 on the pressure tank cover 3 are threadedly connected for feeding and discharge of water. Through the multiple excellent functions such as filtration, adsorption, purification, interaction, activation, and energy storage, the multifunctional water processor 25 can effectively promote the disinfection and sterilization, water purification, and improvement of mouth feel, further ensuring the obtained hydrogen water to be clean, safe and healthy. In addition, after the magnetic resonance in the magnetic field, the permeability, solubility and other excellent properties of the water can be further enhanced, so as to further improve the ability to dissolve and stabilize hydrogen molecules. The permeability of the silica gel is 73.8 barrer (1 barrer=10.sup.−10.Math.cm.sup.3(STP) cm.Math.s.sup.−1.Math.cm.sup.−2.Math.cmHg.sup.−1). Since the polymer composite has good elasticity, the pore structure thereof can be stretched by increasing the pressure, improving the permeability and diffusion coefficient of the hydrogen molecules. Ultra pure hydrogen gas (purity: 99.999%) with a pressure of 0.15 MPa was fed into the second cavity 6 through the air hole 7 for storage (for about 3-month use; the hydrogen gas can be repeatedly fed when it is insufficient). The hydrogen gas stored in the second cavity 6 can be diffused into the membrane-type liner 2 for 1 hour, and then gradually penetrates into the water in the first cavity 5. Meanwhile, the pressure tank 1 is placed on an ultrasonic oscillator to accelerate the diffusion of hydrogen molecules and enable the hydrogen molecules and water to be fully mixed. Then the pressure tank 1 is subjected to standing for 2 h to form a stable hydrogen-in-water structure to obtain hydrogen water with a hydrogen molecule concentration of 3.36 ppm. When the first water port 4 is opened, the hydrogen water in the first cavity 5 is driven by the gas pressure in the second cavity 6 to be automatically discharged.

[0064] A comparison test is performed between a hydrogen water sample prepared by the commonly-used electrolysis method and a hydrogen water sample prepared by the apparatus provided herein. Specifically, the hydrogen water samples are exposed to the environment air at 20° C., and the content of hydrogen molecules is measured respectively at different time points. The results are shown in Table 1, from which it can be concluded that after exposed for 2 h, the hydrogen water sample prepared herein exhibits a higher hydrogen residual rate, which is 30% higher than that of the sample prepared by the common electrolysis method. It shows that the hydrogen water prepared herein has a superior structural stability.

[0065] A cup of the hydrogen water prepared by the apparatus provided herein, which undergoes the treatment of the multifunctional water processor is taken, and determined by 17O-nuclear magnetic resonance spectroscopy (NMR) to have a half-width less than 100 Hz. By comparison, it can be found that the hydrogen content of the hydrogen water undergoing the treatment of the multifunctional water processor is significantly higher than that of the hydrogen water without undergoing the treatment of the multifunctional water processor. At the same time, their hydrogen molecule contents are measured respectively at different time points after exposed to air at 20° C., and the results were shown in Table 1. After the 2-hour exposure, the hydrogen residual rate of the hydrogen water undergoing the treatment of the multifunctional water processor is at least 5% higher than that of the hydrogen water without the treatment of the multifunctional water processor.
