Description

TECHNICAL FIELD

[0001] The present application relates to the field of water supply equipment, in particular to a device and method for providing hydrogen water. BACKGROUND

[0002] The hydrogen-rich water dispenser is an equipment that can inject hydrogen into drinking water. When a user drinks the drinking water containing hydrogen, the effect of hydrogen intake can be achieved. Studies have shown that hydrogen has good effects on removing free radicals in the body, resisting aging, reducing blood pressure, and reducing blood sugar levels. Therefore, various hydrogen-rich water generating devices have appeared in the consumer market. Traditional hydrogen-rich water cups or hydrogen-rich water dispensers mainly consist of a water container and a hydrogen production component. Hydrogen produced by the hydrogen production component enters the drinking water and dissolves in the water. Since hydrogen bubbles have buoyancy, they cannot stay in the water for a long time, resulting in low solubility of hydrogen bubbles in water, making it difficult to achieve the purpose of supplementing hydrogen intake. Therefore, there is still much room for improvement in current hydrogen-rich water dispensers.

[0003] For example, Chinese patent application CN111792718 discloses a hydrogen-rich water generator based on a sustainable hydrogen production device and a generation method. The hydrogen-rich water generator consists of a hydrogen generator and a hydrogen-rich water generator. The hydrogen generator includes a reactor, a buffer, and a cleaner. The hydrogen-rich water generator includes an air inlet pipe for obtaining hydrogen from the cleaner, a water inlet pipe for transmitting a water source, and a water outlet for transmitting hydrogen-rich water. Although this device can generate and transmit hydrogen-rich water, it still has the following defects or deficiencies: in the technical solution disclosed in this patent, the hydrogen-rich water generation process is that the produced hydrogen directly enters the hydrogen-rich water generator through the air inlet pipe. This method can only rely on the hydrogen to dissolve in the water. Without external factors, the solubility of hydrogen is low, and the effect of increasing hydrogen intake cannot be effectively achieved.

[0004] Therefore, it is an urgent problem in the industry to provide a hydrogen-rich water dispenser that can efficiently produce high-concentration hydrogen-rich water and maintain the hydrogen water concentration for a long time. SUMMARY

[0014] Further, the hydrogen-rich water dispenser further comprises a vacuum exhaust unit, and the gas inlet end of the vacuum exhaust unit is connected to the water dispenser body.

[0015] The embodiment also discloses a hydrogen-rich water production method, which comprises the following steps: injecting drinking water into the water dispenser body; after the water injection is completed, forming a negative pressure in the water dispenser body to reduce the solubility of air in the drinking water; starting the hydrogen production unit to generate hydrogen; and spraying the hydrogen after being pressurized by the hydrogen compressor from the plurality of annular porous nozzles, while driving the drinking water to be stirred to increase the contact area of the hydrogen bubbles and the water and improve the solubility of the hydrogen.

[0035] Please refer to Figure 1 , Figure 7 and Figure 8 , the hydrogen-rich water dispenser further comprises a hydrogen production unit 2, the gas outlet of the hydrogen production unit 2 is connected to a hydrogen storage tank 7, and the gas outlet of the hydrogen storage tank 7 is connected to a hydrogen gas pressurizing machine 3. The hydrogen production unit 2 can selectively adopt electrolytic hydrogen production or hydrogen production agent hydrogen production, and electrolytic hydrogen production is selected in the present embodiment. The hydrogen produced by the hydrogen production unit 2 first fills the hydrogen storage tank 7, and the gas outlet of the hydrogen gas pressurizing machine 3 is connected to the water dispenser body 1 through a gas inlet pipeline 4. A valve 41 for controlling the opening and closing of the gas inlet pipeline 4 is arranged on the gas inlet pipeline 4, and the part of the gas inlet pipeline 4 extending into the water dispenser body 1 is arranged along the height direction of the water dispenser body 1, and a plurality of annular porous nozzles 5 are arranged in communication on the part.

[0036] Please refer to Figure 7 , the jet holes 6 are arranged on the inner circumferential wall of the annular porous nozzle 5, the aperture of the jet hole 6 is 0.1-1mm, preferably 0.2-0.5mm, and in the present embodiment, the aperture is 0.3mm. Under the aperture, a large number of hydrogen bubbles can be sprayed in unit volume by the jet hole 6, and the volume of the hydrogen bubbles is appropriate, which can increase the contact area of hydrogen and drinking water in unit volume, and at the same time, the hydrogen bubbles will not have larger buoyancy in the drinking water due to the large volume, which can prolong the residence time of the hydrogen bubbles in the drinking water and improve the solubility of hydrogen in the drinking water.

[0037] The jetting direction of each jet hole 6 is obliquely arranged relative to the tangent direction of the inner ring of the annular multi-hole nozzle 5, and the oblique angle is 20-60 degrees, preferably 30-45 degrees, and is selected as 35 degrees in this embodiment.

[0039] Please refer to Figure 1 The solubility of hydrogen in drinking water is not only related to external factors such as pressure, contact area, etc., but also related to the drinking water itself. The water purification unit 9 can remove impurities dissolved therein, but cannot remove dissolved air. Therefore, in this embodiment, a vacuum exhaust unit 10 is added to the water dispenser body 1. The air inlet end of the vacuum exhaust unit 10 extends into the water dispenser body 1, and forms a negative pressure above the drinking water, so that part of the air dissolved in the drinking water is precipitated and discharged from the water dispenser body 1. In this case, the solubility of hydrogen in the drinking water can be improved.

[0041] S1: The electromagnetic valve 12 is opened, and the drinking water passes through the water purification unit 9 to reach the water dispenser body 1 until the water upper limit setting of the water amount detector 13 is triggered. At this time, the electromagnetic valve 12 is closed, and the water dispenser body 1 stops adding water;

[0042] S2: The vacuum exhaust unit 10 is started, and the air above the drinking water is extracted, and a negative pressure is formed in the water dispenser body 1, so that the solubility of air in the drinking water is reduced;

[0043] S3: Start the hydrogen production unit 2 and close the vacuum exhaust unit 10, the hydrogen in the hydrogen storage tank 7 is pressurized by the hydrogen pressurizing machine 3 and reaches the annular porous nozzle 5 through the gas inlet pipeline 4, and is sprayed out from the spray hole 6, at the same time the hydrogen bubbles stir the drinking water;

[0044] S4: Start the stirring impeller 8 and set it to rotate in the opposite direction of the drinking water, increase the oscillation amplitude of the drinking water, and further improve the solubility of hydrogen in the drinking water.

[0045] Example 2

[0046] Please refer to Figure 3 , according to the hydrogen-rich drinking water machine of the embodiment includes: water dispenser body 1, the water inlet of the water dispenser body 1 is connected to the water source through the water purification unit 9, the water purification unit 9 can remove the impurities dissolved in the water source, the reduction of impurities dissolved in drinking water can improve the solubility of hydrogen in drinking water. The water dispenser body 1 is provided with a water level detector 13, the water inlet side of the water purification unit 9 is provided with a solenoid valve 12, the water level detector 13 and the solenoid valve 12 are electrically connected. When the water level detector 13 detects that the water level in the water dispenser body 1 reaches the highest water level setting, control the solenoid valve 12 to close, when the water level detector 13 detects that the water level in the water dispenser body 1 reaches the lowest water level setting, control the solenoid valve 12 to open, so as to realize the automatic water replenishment of the water dispenser body 1.

[0047] Please refer to Figure 3 、 Figure 7 and Figure 8 , the hydrogen-rich drinking water machine also includes a hydrogen production unit 2, the gas outlet end of the hydrogen production unit 2 is connected with a hydrogen storage tank 7, and the gas outlet end of the hydrogen storage tank 7 is connected with a hydrogen pressurizing machine 3. The hydrogen production unit 2 can select to produce hydrogen by electrolysis or hydrogen production agent, and in this embodiment, hydrogen production agent is selected to produce hydrogen. The hydrogen produced by the hydrogen production unit 2 will first fill the hydrogen storage tank 7, and the gas outlet end of the hydrogen pressurizing machine 3 is connected with the water dispenser body 1 through the gas inlet pipeline 4. The valve 41 for controlling the opening and closing of the gas inlet pipeline 4 is arranged on the gas inlet pipeline 4, and the part of the gas inlet pipeline 4 extending into the water dispenser body 1 is arranged along the height direction of the water dispenser body 1, and a plurality of annular porous nozzles 5 are arranged in communication thereon, and the plurality of annular porous nozzles 5 are arranged in parallel. Each annular porous nozzle 5 is provided with a plurality of spray holes 6 with the same opening direction, and the spray holes 6 are arranged on the inner side wall of the annular porous nozzle 5. The diameter of the spray hole 6 is 0.1-1mm, preferably 0.2-0.5mm, and in this embodiment, it is 0.3mm. Under this diameter, it can be ensured that the spray hole 6 can spray a large number of hydrogen bubbles under unit volume. At the same time, the volume of hydrogen bubbles is appropriate, which can increase the contact area of hydrogen and drinking water under unit volume, and will not cause the hydrogen bubbles to have larger buoyancy in the drinking water, which can prolong the residence time of hydrogen bubbles in the drinking water, and can improve the solubility of hydrogen in the drinking water.

[0048] The jetting direction of each jet hole 6 is obliquely arranged relative to the tangential direction of the inner ring of the annular multi-hole nozzle 5, and the oblique angle is 20-60 degrees, preferably 30-45 degrees, and is selected as 40 degrees in this embodiment. At this angle, the hydrogen gas has a balance of flow rate and flow velocity when jetted. In this embodiment, the opening direction of the jet holes 6 arranged on at least one annular multi-hole nozzle 5 is opposite to that of the jet holes 6 arranged on the other annular multi-hole nozzle 5, that is, the arrangement angle of the plurality of jet holes 6 of at least one annular multi-hole nozzle 5 is such that the drinking water generates clockwise or counterclockwise rotation, while the arrangement angle of the plurality of jet holes 6 of the other annular multi-hole nozzle 5 is such that the drinking water generates opposite counterclockwise or clockwise rotation. In actual application, the proportion of the number of annular multi-hole nozzles 5 with jet holes 6 of different opening directions should be close to half, for example, when the number of annular multi-hole nozzles 5 is odd, the number of annular multi-hole nozzles 5 with jet holes 6 of one opening direction is one more than that of the other opening direction; when the number of annular multi-hole nozzles 5 is even, the number of annular multi-hole nozzles 5 with jet holes 6 of the two opening directions is the same.

[0049] When the valve 41 is opened, the hydrogen gas pressurizer 3 in cooperation with the hydrogen storage tank 7 can press a large amount of hydrogen gas into the annular multi-hole nozzle 5, and the hydrogen gas is quickly jetted out of the jet holes 6. When the hydrogen bubbles are jetted out, the drinking water in the drinking machine body 1 can be driven to rotate along the jetting direction of the hydrogen bubbles. Due to the arrangement of jet holes 6 with different opening directions, the directions of the drinking water rotation are different, so the drinking water can generate stirring effect, which can effectively improve the solubility of hydrogen in the drinking water. The top of the drinking machine body 1 is provided with a pressure sensor 18, which can monitor the pressure in the drinking machine body 1 in real time. When the pressure reaches the set upper limit, the valve at the air inlet pipeline 4 is closed to prevent the drinking water from flowing back through the jet holes 6. The bottom of the drinking machine body 1 is also provided with a water outlet 11, and the valve at the water outlet 11 can be manually opened or electrically opened.

[0050] Please refer to Figure 3 The solubility of hydrogen in drinking water is not only related to external factors such as pressure, contact area, etc., but also related to the drinking water itself. The water purification unit 9 can remove impurities dissolved therein, but cannot remove dissolved air, so in this embodiment, a vacuum exhaust unit 10 is added to the drinking machine body 1. The air inlet end of the vacuum exhaust unit 10 extends into the drinking machine body 1, and by extracting air from the drinking machine body 1, a negative pressure is formed above the drinking water, thereby causing part of the air dissolved in the drinking water to be precipitated. In this case, injecting hydrogen into the drinking water can improve the solubility of hydrogen in the drinking water.

[0051] Please refer to Figure 4The embodiment also discloses a hydrogen-rich water production method applied to the hydrogen-rich water dispenser.

[0052] S1: the electromagnetic valve 12 is opened, and the drinking water reaches the water dispenser body 1 through the water purification unit 9 until the upper limit of the water amount of the water amount detector 13 is triggered, at this time, the electromagnetic valve 12 is closed, and the water adding in the water dispenser body 1 is stopped;

[0053] S2: the vacuum exhaust unit 10 is started, the air above the drinking water is extracted, and the negative pressure is formed in the water dispenser body 1, so as to reduce the solubility of the air in the drinking water;

[0054] S3: the hydrogen production unit 2 is started and the vacuum exhaust unit 10 is closed, the hydrogen in the hydrogen storage tank 7 is pressurized by the hydrogen pressurizing machine 3, then reaches the annular porous nozzle 5 through the air inlet pipeline 4, and is sprayed from the spray hole 6, at the same time, the hydrogen bubbles drive the drinking water to be stirred, so as to improve the solubility of the hydrogen in the drinking water and form the hydrogen-rich water.
