[0002] In recent years, with the improvement of public health awareness, the functional drinking water market presents a diversified development trend. Among them, hydrogen-rich water (including hydrogen molecular water, electrolytic reduction water and alkaline ion water sold on the market) has attracted double attention from the scientific research community and the consumer field due to the reduction effect of the hydrogen contained therein. Studies have shown that hydrogen gas (H2) has selective antioxidant properties and can neutralize harmful free radicals (such as hydroxyl radicals) in the human body. Its small molecular weight and strong penetration characteristics enable it to quickly reach cells and reduce oxidative stress and inflammatory response. Based on this, existing studies have shown that hydrogen-rich water has certain effects on antioxidant, anti-inflammatory, metabolic regulation and neuroprotection.

Among them, the alkaline reducing water generated in the cathode area, and the anode generates acidic water. The hydrogen concentration in the alkaline reducing water obtained by this method is low, and a large amount of acidic water is generated in the process of electrolyzing water. SUMMARY

[0030] Before the embodiments are described in detail, it should be understood that the application is not limited to the detailed structure or element arrangement described below or in the accompanying drawings. The application can be implemented in other ways. Moreover, it should be understood that the language and terminology used herein are used only for descriptive purposes and should not be construed as limiting.

In particular, when describing "one certain element," the application does not limit the number of the element to one, but can include multiple.

[0031] The hydrogen-rich water preparation module can be used to prepare hydrogen-rich water for direct drinking or brewing of beverages. More and more consumers are now paying attention to the health benefits of hydrogen-rich water, such as using hydrogen-rich water to brew beverages, which not only achieves the purpose of health preservation, but also improves the taste of beverages such as coffee and milk tea.

[0032] Please refer to Figure 1 The hydrogen-rich water preparation module 100 provided by the application includes a water supply module 110 for providing water to be electrolyzed, and an electrolysis module 120 connected to the water supply module 110.

[0033] The water source of the water supply module 110 can be tap water 111 or bottled water, which is selected according to the use environment or actual needs, such as in a place where it is convenient to connect to tap water, the water source of the water supply module 110 is mainly tap water 111, which is filtered by a filter 112 in the water supply module to obtain water to be electrolyzed that meets the required drinking water standards. Tap water 111 generally has a certain water pressure, so the water supply module can not need a water pump and can directly deliver the water to be electrolyzed to the electrolysis module 120.

[0034] The electrolysis module 120 comprises a first water inlet pipeline 123, a PEM electrolysis cell 121, and a first water outlet pipeline 124 connected in sequence. The PEM electrolysis cell 121 comprises an anode chamber 1213, a cathode chamber 1212, and a proton exchange membrane 1211 between the anode chamber 1213 and the cathode chamber 1212. The water to be electrolyzed from the water supply module 110 enters the cathode chamber 1212 of the PEM electrolysis cell 121 through the first water inlet pipeline 123, mixes with the generated hydrogen gas in the cathode chamber 1212, and obtains hydrogen-rich water, which is then output through the first water outlet pipeline 124.

[0035] The proton exchange membrane 1211 is, for example, a Nafion membrane produced by DuPont Company, and contains sulfonic acid groups and has hydrophilicity. The present application utilizes the characteristics of the proton exchange membrane itself and proposes the core idea of the present application: in the case that the cathode chamber is filled with water to be electrolyzed, the water absorption of the proton exchange membrane 1211 will cause the water to be electrolyzed in the cathode chamber 1212 to be adsorbed on the proton exchange membrane 1211 and gradually migrate to the anode side of the proton exchange membrane 1211, so that the anode side of the proton exchange membrane 1211 remains wet and can be electrolyzed. Furthermore, the internal pressure of the cathode chamber is greater than the pressure of the anode chamber, and under the action of the pressure difference, the amount of water to be electrolyzed migrating from the cathode chamber 1212 to the anode chamber 1213 will increase, and the electrolysis effect of the PEM electrolysis cell 121 will be better. Of course, in the case that the water to be electrolyzed in the anode chamber 1213 is insufficient, a small amount of water to be electrolyzed or water vapor or humid air can be additionally introduced to keep the proton exchange membrane 1211 on the anode chamber 1213 side wet, so that electrolysis can be continuously performed. By using the PEM electrolysis cell 121 and introducing water to be electrolyzed into the cathode chamber 1212, the discharge amount of oxygen-containing water generated in the anode chamber 1213 can be greatly reduced.

[0036] Reference Figures 5 to 6An exemplary PEM electrolyzer for use in embodiments includes a proton exchange membrane 1211, a cathode chamber 1212, an anode chamber 1213, a cathode water inlet 1214, a cathode water outlet 1216, an anode water inlet 1215, and an anode water outlet 1217. The cathode chamber includes a cathode bipolar plate and a cathode catalyst, and the anode chamber includes an anode bipolar plate and an anode catalyst. The input end of a first water inlet pipeline 123 is connected to the water supply module 110, and the output end of the first water inlet pipeline 123 is in communication with the cathode water inlet 1214. The water to be electrolyzed in the pipeline is delivered to the cathode chamber 1212. A small amount of water to be electrolyzed passes through the proton exchange membrane 1211 to the anode chamber 1213. Oxygen-containing water or oxygen-containing water vapor generated after electrolysis in the anode chamber 1213 is discharged through the anode water outlet 1217. The PEM electrolyzer in the example is provided with an anode water inlet 1215. A small amount of water to be electrolyzed can be introduced into the anode water inlet 1215 as needed for electrolysis. The hydrogen protons generated in the anode chamber 1213 enter the cathode chamber 1212 through the proton exchange membrane 1211, obtain electrons, and generate hydrogen gas, which is mixed directly with the water to be electrolyzed in the cathode chamber 1212 to obtain hydrogen-rich water.

[0037] It should be noted that the water to be electrolyzed undergoes an oxygen evolution reaction in the anode chamber 1213 of the PEM electrolyzer 121, generating oxygen, hydrogen ions, and electrons. The electrons flow to the cathode chamber 1212 through an external circuit, and the hydrogen ions pass through the proton exchange membrane 1211 into the cathode chamber 1212, where they obtain electrons to generate hydrogen gas. In actual applications, the commonly used proton exchange membrane 1211 contains a certain amount of sulfonic acid group and has hydrophilicity, and cannot completely prevent water molecules from passing through. Therefore, in the case of introducing a large amount of water to be electrolyzed into the cathode chamber 1212, a small amount of water will penetrate the proton exchange membrane 1211 and enter the anode chamber 1213 for electrolysis. Therefore, it is not necessary to additionally introduce a large amount of water to be electrolyzed into the anode chamber 1213 for electrolysis. Compared with the prior art, in which a large amount of water to be electrolyzed is introduced into the anode chamber for electrolysis, the generation of oxygen-rich water in the anode chamber 1213 is greatly reduced. In addition, in the present application, the hydrogen gas generated by introducing a large amount of water to be electrolyzed into the cathode chamber 1211 is mixed directly with the water to be electrolyzed in the cathode chamber 1212 to obtain hydrogen-rich water.

[0038] In some embodiments, the hydrogen-rich water preparation module 100 includes a control module (not shown in the figure) electrically connected to the water supply module and the electrolysis module for controlling the operation of the hydrogen-rich water preparation module 100.

[0039] In some embodiments, as shown in Figures 2 to 3 The electrolysis module 120 also includes an auxiliary electrolyzer 122 for preparing alkaline hydrogen-rich water.

[0040] The electrolysis module 120 further comprises an auxiliary electrolysis tank 122 for preparing alkaline hydrogen-rich water, the auxiliary electrolysis tank 122 comprising an anode chamber, a cathode chamber, and a diaphragm between the anode chamber and the cathode chamber for allowing ions to pass through and isolating gas, such as an ion exchange membrane. The principle of electrolysis of the auxiliary electrolysis tank 122 is that water containing ions (sodium ions, potassium ions, calcium ions, chloride ions, etc.) is respectively introduced into the anode chamber and the cathode chamber of the auxiliary electrolysis tank 122. In the process of electrolysis, oxygen and hydrogen ions are generated in the anode chamber by electrolysis, and hydrogen and hydroxyl ions are generated in the cathode chamber by electrolysis. Among them, cations are attracted to the cathode chamber, and anions are attracted to the anode chamber. Therefore, the anode chamber generates oxygen-containing acidic water, and the cathode chamber generates alkaline hydrogen-rich water.

[0041] In some embodiments, as shown in Figure 2 The auxiliary electrolysis tank 122 is connected in parallel with the PEM electrolysis tank 121, that is, the first water inlet pipeline 123 is connected to the water inlets of the PEM electrolysis tank 121 and the auxiliary electrolysis tank 122, respectively. For the auxiliary electrolysis tank 122, the anode chamber and the cathode chamber of the auxiliary electrolysis tank 122 need to be respectively introduced into the water to be electrolyzed to ensure that there are sufficient conductive ions in the anode chamber and the cathode chamber of the auxiliary electrolysis tank 122. The cathode water outlet 1216 of the PEM electrolysis tank 121 and the cathode water outlet of the auxiliary electrolysis tank 122 are respectively connected to the first water outlet pipeline 124, so that the hydrogen-rich water output by the PEM electrolysis tank 121 and the weak alkaline hydrogen water output by the auxiliary electrolysis tank 122 are mixed to obtain weak alkaline hydrogen-rich water.

[0042] Specifically, when the auxiliary electrolysis tank 122 is connected in parallel with the PEM electrolysis tank 121 between the first water inlet pipeline 123 and the first water outlet pipeline 124, the water to be electrolyzed can be selectively electrolyzed by the PEM electrolysis tank 121 and the auxiliary electrolysis tank 122 through the control valve on the pipeline, and the hydrogen-rich water generated by electrolysis is mixed on the first water outlet pipeline 124 to obtain weak alkaline hydrogen-rich water. For example, when the user selects weak alkaline hydrogen-rich water, the control module controls the control valve on the first water inlet pipeline 123 to open, so that the water to be electrolyzed enters the PEM electrolysis tank 121 and the auxiliary electrolysis tank 122, respectively, and the hydrogen-rich water generated by electrolysis of the PEM electrolysis tank 121 and the auxiliary electrolysis tank 122 is mixed on the first water outlet pipeline 124 to obtain weak alkaline hydrogen-rich water.

[0043] In some embodiments, as shown in Figure 3 The auxiliary electrolysis tank 122 is connected in series with the PEM electrolysis tank 121.

[0044] When the auxiliary electrolyzer 122 is connected in series with the PEM electrolyzer 121, that is, the auxiliary electrolyzer 122 is connected in series on the first outlet water pipeline 124, the water to be electrolyzed first flows through the PEM electrolyzer 121 for electrolysis, and the hydrogen-rich water obtained from the cathode chamber 1212 of the PEM electrolyzer 121 then flows through the auxiliary electrolyzer 122 and enters the cathode chamber of the auxiliary electrolyzer 122, while an appropriate amount of water to be electrolyzed is introduced into the anode chamber of the auxiliary electrolyzer 122 for electrolysis, and the alkaline hydrogen-rich water is obtained in the cathode chamber of the auxiliary electrolyzer 122. The hydrogen-rich water technical solution greatly improves the content of hydrogen through twice electrolysis, and can also selectively prepare alkaline hydrogen-rich water. For example, when neutral hydrogen-rich water is needed, the power supply of the auxiliary electrolyzer 122 can be turned off, so that the hydrogen-rich water flowing out of the PEM electrolyzer 121 flows through the cathode chamber of the auxiliary electrolyzer 122 without the need for secondary electrolysis, and directly flows into the first outlet pipeline 124.

[0045] In some embodiments, the hydrogen-rich water after electrolysis by the PEM electrolyzer 121 and the auxiliary electrolyzer 122 flows through the first outlet water pipeline 124, and the first outlet water pipeline 124 is provided with a PH monitoring device 137 for monitoring the weak alkalinity of the hydrogen-rich water, such as through color display or PH value display. Further, the monitoring information of the PH monitoring device 137 can be fed back to the control module in real time, and the alkalinity of the hydrogen-rich water can be adjusted by controlling the current, voltage, water inflow and other parameters of the PEM electrolyzer or the auxiliary electrolyzer.

[0046] In some embodiments, the first outlet water pipeline 124 is provided with a flow meter, and the flow meter transmits a signal to the control module, and the control module controls the water inflow of the first water inflow pipeline 123.

[0047] In some embodiments, the hydrogen-rich water preparation module 100 further comprises a temperature control module 130, which comprises a refrigeration unit 132, a heating unit 131, an ice-making unit 133, and a control unit (not shown in the figure) connected in parallel with each other. The refrigeration unit 132 provides cold to the hydrogen-rich water flowing therethrough, which can be a compressor refrigeration or a semiconductor refrigeration, and the present application does not make specific limitations; the heating unit 131 provides heat to the hydrogen-rich water flowing therethrough, which can be a storage water heating, such as a heating boiler; the ice-making unit 133 can make hydrogen-rich ice blocks from the hydrogen-rich water flowing therethrough, which comprises an evaporator, a compressor providing a refrigeration cycle, and a condenser, and the ice-making unit can also be in other forms, for example, using semiconductor refrigeration technology to make ice. The control unit can control the refrigeration unit 132, the heating unit 131, and the ice-making unit 133 to selectively run independently or simultaneously or not to run. For example, when the user indicates to select the ice water mode, part of the hydrogen-rich water output from the first water outlet pipeline 124 is directly output to the cup, and the other part enters the ice-making unit 133, and after the ice-making unit makes ice blocks, the ice blocks are directly added to the cup to form hydrogen-rich ice water; when the user selects normal temperature hydrogen-rich water, the above three units do not run, and the hydrogen-rich water is directly output to the cup through the normal temperature hydrogen-rich water pipeline 134.

[0048] In some embodiments, a gas-liquid mixing unit 135 is arranged on the hydrogen-rich water output pipeline 136 connected to the output end of the refrigeration unit 132 and the heating unit 131, respectively. Generally, after the hydrogen-rich water passes through the refrigeration unit 132 or the heating unit 131, the dissolved hydrogen in the hydrogen-rich water decreases, and a large amount of bubbles may be formed in the solution on the hydrogen-rich water output pipeline 136, causing the dissolved hydrogen in the hydrogen-rich water to escape and reducing the hydrogen content of the hydrogen-rich water. The present application provides a gas-liquid mixing unit 135 arranged on the hydrogen-rich water output pipeline 136 connected to the output end of the refrigeration unit 132 and the heating unit 131, which re-contact the hydrogen-rich water in the pipeline to dissolve as much hydrogen as possible into the hydrogen-rich water. Specifically, the gas-liquid mixing unit 137 can be used to increase the pipeline pressure or / and increase the specific surface area of gas-liquid contact, for example, a pipeline micro-nano bubble technology can be used, that is, a nano-bubble generating device is arranged in the pipeline, which can cut the hydrogen-rich water into nano-bubbles to increase the contact area between water and hydrogen and provide hydrogen solubility.

[0049] In some embodiments, the present application also provides a beverage preparation device 001, which comprises: a control module 300 for controlling the operation of the entire brewing device according to the user's indication; a hydrogen-rich water preparation module 100 as described above; a brewing module 200 in communication with the hydrogen-rich water output end of the hydrogen-rich water preparation module 100, which can specifically comprise a charging assembly for storing powder or liquid material of the beverage, such as milk powder, sugar powder, milk tea powder, coffee powder, etc., and a stirring assembly for mixing hydrogen-rich water with powder or liquid material.

[0050] The charging assembly of the brewing module 200 can also include a coffee bean grinding component to meet the demand of on-site instant grinding and instant brewing. The hydrogen-rich water preparation module 100 as described above comprises a control module, which can be integrated on the control module 300 or arranged separately.

[0051] The beverage preparation device 001 provided by the present application can be a table-type brewing device, such as a table-type hydrogen-rich water coffee machine, or a cabinet-type brewing device, such as an unmanned vending hydrogen beverage preparation device.

[0052] After obtaining the user's brewing instruction, the control module 300 controls the hydrogen-rich water preparation module 100 to start preparing hydrogen-rich water, and the prepared hydrogen-rich water enters the stirring assembly. After mixing the hydrogen-rich water with the powder or liquid material, the beverage is output to the cup. Of course, the hydrogen-rich water can also be output without the stirring device, simultaneously or sequentially with the powder or liquid material, into the cup. When the selected beverage needs to be added with ice, the hydrogen-rich water preparation module 100 first adds the ice cubes prepared by the ice-making unit 133 into the cup, and then outputs the beverage or hydrogen-rich water.

[0053] The concepts described herein can be implemented in other forms without departing from the spirit and characteristics thereof. The disclosed specific embodiments should be considered illustrative rather than restrictive. Therefore, the scope of the present application is determined by the appended claims, not by these descriptions. Any changes within the literal meaning and equivalent scope of the claims should be considered within the scope of the claims.
