Description

[Technical Field]

[0001] The present disclosure relates to a bubble water generator, and in particular to a water server capable of producing micro-nano hydrogen bubble water. [Background technology]

[0002] Carbonated drinks have a certain position in the beverage market, where the carbon dioxide contained in the drink bursts out in the form of bubbles when it enters the mouth, creating a different mouthfeel and enhancing the cooling sensation. Carbonated drinks have an image of being refreshing and thirst-quenching.

[0003] Traditional carbonated drinks usually contain a high amount of sugar, which can be physically taxing on the drinker. Therefore, carbonated water makers have recently appeared on the market, allowing people to add carbon dioxide to drinking water themselves to create aerated water. This not only makes the water sugar-free, but also provides a better taste and visual enjoyment than regular drinking water, increasing the desire to drink water on a daily basis.

[0004] However, commercially available carbonated water makers generally require regular purchase of carbon dioxide refill bottles, which increases the cost of drinking water, so there is a need to develop an aerated water maker that does not require continuous purchase of refill bottles. Summary of the Invention [Problem to be solved by the invention]

[0005] Prior art technologies, such as Taiwan Patent No. M638129, include hydrogen water generators that dissolve hydrogen in water before drinking it, but this not only tastes unpleasant, but also has low hydrogen solubility, resulting in insufficient hydrogen intake by the human body. [Means for solving the problem]

[0006] In order to solve the above problems, the present disclosure provides a water electrolysis device comprising: a cathode cell that electrolyzes water to produce hydrogen gas and has a water inlet and a water outlet that communicates with the water inlet; an anode cell that electrolyzes water to produce oxygen gas and is connected to the cathode cell; a cation exchange membrane that is provided between the cathode cell and the anode cell; a pump that is connected to the water outlet of the cathode cell and extracts the hydrogen gas and the water; and a mixing cell that has a water inlet connected to the pump and a water outlet that communicates with the water inlet and into which the hydrogen gas and the water flow, the mixing cell maintaining a pressure of 100 PSI to 125 PSI so that the hydrogen gas that has flowed in dissolves in the water to form hydrogen water.

[0007] The micro-nano hydrogen bubble water generator according to the present disclosure electrolyzes water to generate hydrogen gas, creates high pressure using a pump to dissolve the hydrogen gas in the water to produce hydrogen water, and produces bubbles using the hydrogen gas contained in the hydrogen water to produce bubble water, so there is no need to regularly purchase a carbon dioxide refill bottle.Preferably, the micro-nano hydrogen bubble water generator is a water server that can produce hydrogen water.

[0008] In the present disclosure, the cathode chamber and the anode chamber are separated by the cation exchange membrane, which prevents hydrogen ions generated by electrolyzing water and the generated hydrogen gas from flowing into the anode chamber so that the hydrogen gas in the cathode chamber can be recovered.

[0009] In one embodiment, the micro-nano hydrogen bubble water generator further includes a water tank connected to the water inlet of the cathode chamber, and the water flow direction is such that the water flows from the water tank to the cathode chamber when the pump is operating.

[0010] In one embodiment, a check valve is provided in the water supply pipe to direct the water flow from the water reservoir to the water inlet of the cathode cell. Preferably, the check valve connects the water supply pipe to the water supply pipe, and the water supply pipe is connected to an external water source, such as bottled water, to increase alternative water sources and improve convenience of use.

[0011] In one embodiment, the anode chamber is provided with an anode catalytic coating, which is in direct contact with the cation exchange membrane and has an area smaller than that of the cation exchange membrane. The cathode chamber is also provided with a cathode catalytic coating, which is in direct contact with the cation exchange membrane and has an area smaller than that of the cation exchange membrane. The present disclosure provides an anode catalytic coating and a cathode catalytic coating to increase the reaction area and improve electrolysis efficiency.

[0012] In one embodiment, the micro-nano hydrogen bubble water generator according to the present disclosure comprises a water tank connected to the water inlet of the cathode cell, a pump connected to the water tank, and a chamber connecting the pump to the anode cell.

[0013] In one embodiment, the anode cell according to the present disclosure further comprises an inlet connected to the chamber and an outlet connected to the chamber, the inlet being located lower than the outlet, which is advantageous for discharging oxygen gas.

[0014] In the present disclosure, the pump sends water from the water supply pipe to the water intake pipe, and after passing through the pump and the water supply pipe in sequence, reaches the chamber. The water in the chamber is sent to the inlet of the anode cell via the water inlet pipe, flows out from the outlet of the anode cell, carries away oxygen gas generated in the anode cell, and returns to the chamber along the drain pipe, where the oxygen gas is discharged from the exhaust port at the top of the chamber, and water circulates between the chamber and the anode cell. In addition, since heat is generated during the oxidation reaction in the anode cell, circulating water between the chamber and the anode cell also serves as cooling.

[0015] In one embodiment, the water outlet is connected to a pressure pipe, and the water outlet of the mixing tank is connected to the pressure pipe via a delivery pipe, and the delivery pipe is equipped with an electromagnetic valve. When the micro-nano hydrogen bubble water generator starts to supply water, the electromagnetic valve opens, the hydrogen water flows through the pressure pipe, and the pressure pipe limits the flow resistance of the water outlet, so that the hydrogen gas in the mixing tank is further dissolved in the hydrogen water, increasing the hydrogen content of the hydrogen water.

[0016] The ball valve can change the water source, the check valve can ensure that the water or hydrogen gas flows in one direction, the solenoid valve is a switch that controls whether water, hydrogen gas, or hydrogen water flows, and the pump, pump, and pressure control can be combined to ensure that the water or hydrogen gas flows in one direction.

[0017] In other words, when a user presses the water outlet button to drink water, the cathode chamber produces hydrogen gas, which is then pumped into the mixing bottle to form hydrogen water at high pressure (approximately 100-125 PSI). The solenoid valve opens at the same time, and the pressure pipe restricts the flow rate of the water outlet, forming a resistance. This increases the pressure in the mixing chamber, allowing more hydrogen gas to dissolve in the hydrogen water and improve the hydrogen content of the hydrogen water. Because the pressure in the mixing chamber is greater than the external pressure of 1 atmosphere (i.e., 14.7 PSI), the hydrogen water leaves the mixing chamber and reaches the drinking bottle. The hydrogen gas dissolved in the hydrogen water at high pressure dissipates into a large number of tiny hydrogen bubbles, forming bubbly water, which can remain milky white for approximately 60 seconds.

[0018] In one embodiment, the micro-nano hydrogen water bubble generator is housed in a case with a button connected to a control unit, preferably a water discharge button, which facilitates user operation.

[0019] In one embodiment, the water electrolysis device, the pump, and the mixing tank are installed in a case, and the water leakage sensor is installed in the case and used to detect whether there is water pooling on the bottom surface of the case.

[0020] In one embodiment, the micro-nano hydrogen bubble water generator includes a water quality sensor connected before the water inlet of the cathode cell.

[0021] In one embodiment, the micro-nanometer hydrogen bubble water generator includes a pressure sensor connected to the mixing tank.

[0022] As described above, the micro-nano hydrogen bubble water generator of the present disclosure generates hydrogen gas in real time by electrolyzing water, then produces hydrogen water under high pressure in a mixing tank, and finally, after the hydrogen water is released, the hydrogen gas contained in the hydrogen water is turned into bubbles, eliminating the need to regularly purchase carbon dioxide refill bottles, and has market potential.Furthermore, the micro-nano hydrogen bubble water generator of the present disclosure can add larger amounts of hydrogen gas to drinking water than hydrogen water generators, and can coat the hydrogen gas with micron- or nano-sized bubbles, thereby increasing the user's intake and absorption rate. [Brief explanation of the drawings]

[0023] [Figure 1] FIG. 2 is an exploded schematic view of the first embodiment. [Figure 2] FIG. 10 is a schematic diagram of the configuration of a second embodiment. [Figure 3] FIG. 10 is a schematic view of the external appearance of Example 3. DETAILED DESCRIPTION OF THE INVENTION

[0024] The following provides several operation methods to describe the embodiments of the present disclosure, and those skilled in the art can easily understand the advantages and effects of the present disclosure through the contents of this specification, and can make various modifications and changes to the contents of the present disclosure to implement or apply them without departing from the spirit of the present disclosure.

[0025] Example 1: Micro-nano hydrogen bubble water generator

[0026] As shown in FIG. 1, the micro-nano hydrogen bubble water generator 1 of the present disclosure includes a water electrolysis device 10 that can use, for example, solid electrolysis technology. In this embodiment, the water electrolysis device 10 includes a cathode chamber 101 that electrolyzes water to produce hydrogen gas and has a water inlet 1011 and a water outlet 1012 that communicates with the water inlet 1011, an anode chamber 102 that electrolyzes water to produce oxygen gas and is connected to the cathode chamber 101, and a cation exchange membrane 103 that is provided between the cathode chamber 101 and the anode chamber 102, a pump 11 that is connected to the water outlet 1012 of the cathode chamber 101 and that extracts the hydrogen gas and the water, and a mixing chamber 12 that has a water inlet 121 connected to the pump 11 and a water outlet 122 that communicates with the water inlet 121 and into which the hydrogen gas and the water are introduced, and the pressure within the mixing chamber is set to 100 PSI to 125 PSI so that the introduced hydrogen gas dissolves in the water to form hydrogen water. In other words, after the micro-nano hydrogen bubble water generator 1 initially supplies water, the pump 11 continues to maintain the pressure in the mixing tank 12 at 100 PSI to 125 PSI so as to form hydrogen water.

[0027] Example 2: Micro-nano hydrogen bubble water generator

[0028] As shown in FIG. 2, first, the water outlet 122 is connected to a pressure pipe 13, which restricts the flow rate of the water outlet 122 to form a resistance, thereby increasing the internal pressure of the mixing tank 12, thereby dissolving more hydrogen gas in the mixing tank 12 into the hydrogen water and increasing the hydrogen content of the hydrogen water.

[0029] Second, the micro-nano hydrogen bubble water generator 1 includes a water tank 14 connected to the water inlet 1011 of the cathode chamber 101 via a water supply pipe 141, and the water flows from the water tank 14 to the cathode chamber 101. The water supply pipe 141 is provided with a check valve 1411, which is connected to a water supply pipe (not shown) and the water supply pipe 141. The water supply pipe (not shown) is connected to an external water source, such as bottled water, to increase alternative water sources and improve convenience of use. In this embodiment, the check valve 1411 may be a ball valve.

[0030] Third, the anode chamber 102 is provided with an anode catalytic coating (not shown), which is in direct contact with the cation exchange membrane 103. The cathode chamber 101 is also provided with a cathode catalytic coating (not shown), which is in direct contact with the cation exchange membrane 103. The area of ​​the anode catalytic coating is smaller than that of the cation exchange membrane 103, and the area of ​​the cathode catalytic coating is smaller than that of the cation exchange membrane 103. At the same time, the anode catalytic coating (not shown) and the cathode catalytic coating (not shown) each have holes (not shown), so that the anode catalytic coating and the cathode catalytic coating each cover only a portion of the cation exchange membrane 103. Preferably, the holes in the anode catalytic coating and the cathode catalytic coating correspond to each other, and the hydrogen gas or oxygen gas is generated at the edges of the holes.

[0031] Fourth, the pump 11 is connected to the water electrolysis device 10 via a connecting pipe 111, i.e., connected to a water outlet 1012 of the cathode cell 101 via the connecting pipe 111, and the pump 11 is connected to a water inlet 121 of the mixing cell 12 via a communicating pipe 112, and the communicating pipe 112 is provided with a check valve 1121 that controls the flow direction of the hydrogen gas and the water to flow from the water electrolysis device 10 via the pump 11 to the mixing cell 12.

[0032] Fifth, the water outlet 122 of the mixing tank 12 is connected to the pressurized pipe 13 via a delivery pipe 123, and a solenoid valve 1231 is provided on the delivery pipe 123. When the micro-nano hydrogen bubble water generator 1 starts to supply water, the solenoid valve 1231 opens, and the hydrogen water flows through the pressurized pipe 13. The pressure pipe 13 limits the resistance caused by the flow rate of the water outlet 122, so that the hydrogen gas in the mixing tank 12 is further dissolved in the hydrogen water, increasing the hydrogen content of the hydrogen water.

[0033] Sixth, the micro-nano hydrogen bubble water generator 1 includes a whisk 15 connected to the pressure pipe 13. By using the whisk 15, the foaming effect can be further improved.

[0034] Therefore, by pressurizing the water through components such as pump 11 and solenoid valve 1231, a large amount of hydrogen gas is dissolved in the water at high pressure, and when the water comes out, the pressure returns to 1 atmosphere, so the hydrogen gas becomes supersaturated at this moment. When the water comes out, the water passes through bubbler 15, and the supersaturated hydrogen gas escapes, generating a large amount of micron and even nano bubbles, making the water milky white.

[0035] Seventh, the micro-nano hydrogen bubble water generator 1 includes a pump 16 connected to the water supply pipe 141 and a chamber 17 connecting the pump 16 and the anode cell 102, wherein the pump 16 is connected to the water supply pipe 141 via a water suction pipe 161, which is located between the check valve 1411 and the water electrolysis device 10 and connected to the water supply pipe 141. The pump 16 is also connected to the chamber 17 via a water supply pipe 162. Specifically, in this embodiment, a three-way valve 1412 is provided which is connected to the water inlet 1011 of the cathode cell 101, connected to the water tank 14 via the water supply pipe 141, and connected to the pump 16 via the water suction pipe 161.

[0036] Eighth, the anode cell 102 of the water electrolysis apparatus 10 includes an inlet 1022 connected to the chamber 17 and an outlet 1021 connected to the chamber 17, and the inlet 1022 is located lower than the outlet 1021. The inlet 1022 is connected to the chamber 17 via a water inlet pipe 172, and the outlet 1021 is connected to the chamber 17 via a drain pipe 171. The chamber 17 is a water tank with a volume of approximately 80 milliliters, and an exhaust outlet 173 is provided at the top of the chamber 17.

[0037] In the present disclosure, water in the water supply pipe 141 is sent to the water intake pipe 161 by the pump 16, and after passing through the pump 16 and the water supply pipe 162 in sequence, reaches the chamber 17. The water in the chamber 17 is sent to the inlet 1022 of the anode cell 102 via the water inlet pipe 172, flows out from the outlet 1021 of the anode cell 102, carries away oxygen gas generated in the anode cell 102, and returns to the chamber 17 along the drain pipe 171. The oxygen gas is discharged from the exhaust port 173 at the top of the chamber 17, and water circulates between the chamber 17 and the anode cell 102. More specifically, when the micro-nano hydrogen bubble water generator 1 is operated, the generated oxygen gas rises, creating a vacuum tension that rises in the drain pipe 171, causing water to flow from the water inlet pipe 172 in the direction of the drain pipe 171.

[0038] Ninth, the micro-nano hydrogen bubble water generator 1 includes a control unit (not shown) electrically connected to the water electrolysis device 10, the pump 11, the pump 16, and the solenoid valve 1231. The present disclosure provides bubble water in real time by regulating electrolysis and water supply using the control unit.

[0039] Tenth, the arrows indicate the direction of flow of hydrogen gas, oxygen gas, or water.

[0040] Eleventh, the micronano hydrogen bubble water generator 1 according to the present disclosure is equipped with a plurality of sensors to ensure smooth operation of the micronano hydrogen bubble water generator 1. Specifically, the micronano hydrogen bubble water generator 1 includes a case 18, in which all of the above components are installed, and which further includes a water quality sensor 191, a water leakage sensor 192, and a pressure sensor 193.

[0041] The water quality sensor 191 is connected before the water inlet of the cathode chamber 101. In this embodiment, the water quality sensor 191 is connected between the water storage tank 14 and the cathode chamber 101, and preferably between the three-way valve 1412 and the water storage tank 14. The water quality sensor 191 is also connected to the control unit. This allows the water source to be monitored while it is entering the water electrolysis apparatus 10, and the water electrolysis apparatus 10 to be stopped in the event of an abnormality in the water quality, thereby preventing contamination of the water electrolysis apparatus 10 and maintaining a long lifespan. In this embodiment, the water quality sensor 191 is a total dissolved solids sensor.

[0042] The water leakage sensor 192 is provided on the inner bottom surface of the case 18 and connected to the control unit so as to detect whether there is any water accumulation due to a water leak in the piping on the inner bottom surface of the case 18. In another embodiment, the water leakage sensor 192 may be installed below a position where there is a possibility of water leakage, so that in the event of a water leak, water droplets will directly fall on the water leakage sensor 192. When a water leak occurs, the micro-nano hydrogen bubble water generator 1 can suspend all operations and emit an alarm sound and alarm light signal.

[0043] A pressure sensor 193 is connected to the mixing tank 12, and in this embodiment, is connected to the water outlet of the mixing tank 12. At the same time, the pressure sensor 193 is connected to the control unit. Therefore, when the pressure sensor 193 detects that the water flowing out of the mixing tank 12 is below a default value, the micro-nano hydrogen bubble water generator 1 can stop all operations and issue an alarm sound and an alarm lamp signal.

[0044] Finally, the micro-nano hydrogen bubble water generator 1 according to the present disclosure electrolyzes water to produce hydrogen water and form bubble water, eliminating the need to regularly purchase carbon dioxide refill bottles, and has greater market potential.

[0045] Example 3: Micro-nano hydrogen bubble water generator

[0046] As shown in Figure 3, the water tank 14 of the micro-nano hydrogen bubble water generator 1 is located away from the whisk 15. The micro-nano hydrogen bubble water generator 1 is housed in a case 18, except for the water tank 14 and the whisk 15. The case 18 is provided with a button 181, which is connected to a control unit (not shown) and functions as a water outlet button. Finally, to prevent dust in the air from contaminating the water in the chamber, a through-hole is not provided separately at the top of the case 18 and connected to the exhaust port (not shown) of the chamber (not shown), but the exhaust port is also located inside the case 18.
