Abstract
Description
Technical Field
[0001] This utility model relates to the field of drinking water equipment technology, and in particular to a gas-liquid mixing mechanism and a hydrogen-rich solution preparation device. Background Technology
[0002] In daily life, as people's living standards continue to improve, all kinds of household appliances are gradually entering our homes, and water dispensers are one of them. Moreover, my country has a vast territory, and the water quality in some areas is relatively poor. Therefore, safe drinking water is also necessary, and water dispensers are one of the ways to solve these problems.
[0003] Existing water dispensers have relatively limited functions, at most heating, cooling, or sterilizing drinking water. These functions don't offer much benefit to human health. However, research shows that mixing hydrogen gas with drinking water to create a hydrogen-rich aqueous solution can provide some health benefits. Therefore, achieving high solubility in hydrogen-water mixtures is a challenge. This also applies to other gases beneficial to human health or other applications requiring high-solubility gas-liquid mixing.
[0004] Currently, there are two main methods: one is to input hydrogen gas into a closed structure containing water, wait a period of time, and then output the water from the closed structure to obtain a hydrogen-rich aqueous solution; the other is to use a motor to drive a water turbine to mix hydrogen gas and water, thereby outputting a hydrogen-rich aqueous solution. However, the hydrogen solubility in the hydrogen-rich aqueous solution produced by these two methods is relatively low, and continuous output cannot be achieved when mixing at high concentrations. Therefore, a gas-liquid mixing mechanism and a hydrogen-rich solution preparation device are needed that can efficiently mix hydrogen gas and aqueous solution, maintain high hydrogen solubility in the aqueous solution, and ensure continuous output. Utility Model Content
[0005] The main purpose of this invention is to provide a gas-liquid mixing mechanism and a hydrogen-rich solution preparation device that can efficiently mix hydrogen and aqueous solution and maintain continuous output while ensuring high hydrogen solubility in aqueous solution.
[0006] This utility model proposes a gas-liquid mixing mechanism and a hydrogen-rich solution preparation device, including a mixing tank, a liquid input device, an atomizing device and a gas input device;
[0007] The mixing tank has an air inlet on its side bottom, a liquid outlet at its bottom, and a liquid inlet at its top.
[0008] The liquid input device is connected to the atomizing device and then to the liquid inlet of the tank. The gas input device is connected to the air inlet of the tank. The liquid output by the liquid input device is atomized by the atomizing device and then input into the mixing tank to mix with the gas in the mixing tank. The pressure in the mixing tank is increased by continuously and controlledly inputting gas or simultaneously and controlledly inputting liquid and gas, thereby ensuring the high solubility of the mixed gas in the liquid.
[0009] Preferably, the mixture also includes a water level sensor, one interface of which is used to detect whether the water level in the mixing tank is insufficient, and the other interface is used to detect whether the water level in the mixing tank is too high.

[0016] The gas-liquid mixing mechanism includes a mixing tank, a gas generator, a water level sensor, a pressure sensor, an atomizing nozzle, and a high-pressure pump. The mixing tank has an air inlet on its side bottom, a liquid outlet at its bottom, and a liquid inlet at its top.
[0017] The water tank is connected to the input end of the high-pressure pump, and the output end of the high-pressure pump is connected to the atomizing nozzle. The atomizing nozzle is connected to the liquid inlet of the mixing tank. The water in the water tank is pressurized by the high-pressure pump and then input into the mixing tank through the liquid inlet.
[0018] The gas generator is connected to the liquid inlet via a gas input solenoid valve, and hydrogen is generated by the gas generator and input into the mixing tank through the liquid inlet.
[0019] One interface of the water level sensor is used to detect whether the water level in the mixing tank is insufficient, and the other interface is used to detect whether the water level in the mixing tank is too high, so as to ensure that the liquid level inside the tank is within the set range. The pressure sensor detects the pressure inside the mixing tank, thereby controlling the input of gas and liquid, and ensuring that the pressure inside the mixing tank is stable within the set range.
[0020] The liquid outlet of the tank is connected to the liquid outlet mechanism via an output solenoid valve, through which the mixed hydrogen-rich solution is output.
[0021] Preferably, it also includes a drain pipe, and the liquid outlet of the tank is connected to the drain pipe through a drain solenoid valve.
[0022] Preferably, it also includes a control panel, which is connected to the control circuit board, and the control panel controls the working status of the gas-liquid mixing mechanism and the liquid outlet mechanism through the control circuit board.
[0023] The beneficial effects of this invention, including the gas-liquid mixing mechanism and the hydrogen-rich solution preparation device, are as follows:
[0024] 1. By atomizing the liquid and mixing it with the gas, the dissolution rate of the gas can be increased, thus reaching the maximum solubility more quickly.
[0025] 2. When the gas is introduced from below the liquid surface, it can pass through the liquid surface and then mix with the atomized liquid above, thereby increasing the dissolution rate of the gas and allowing it to reach maximum solubility more quickly.

The pressure inside the mixing tank is obtained through a pressure sensor, and the gas input device and liquid input device are controlled by the control circuit board to maintain the pressure inside the mixing tank, thereby maintaining the solubility of the hydrogen-rich solution inside the mixing tank.

[0035] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.
[0036] Reference Figures 1 to 6 An embodiment of the gas-liquid mixing mechanism of this utility model is proposed:
[0037] A gas-liquid mixing mechanism includes a mixing tank 6, a water level sensor 7, a pressure sensor, a liquid input device, an atomizing device, and a gas input device.
[0038] In this embodiment, the liquid input device is a high-pressure pump 5, the gas input device is a gas generator 8, and the atomizing device is an atomizing nozzle.
[0039] The mixing tank 6 has an air inlet 63 on the bottom side of its side, and two detection holes 64 of different heights on the other side of the mixing tank 6 opposite to the air inlet 63. The mixing tank 6 has a liquid outlet 62 at the bottom and two liquid inlets 61 at the top.
[0040] The input end of the high-pressure pump 5 is connected to the water tank 4 or a water pipe, and the output end of the high-pressure pump 5 is connected to the atomizing nozzle. The atomizing nozzle is connected to the liquid inlet 61 of the mixing tank 6. The water is pressurized by the high-pressure pump 5 and then fed into the mixing tank 6 through the liquid inlet 61.
[0041] The water level sensor 7 has one interface located in the lower detection hole 64 to detect whether the water level in the mixing tank 6 is insufficient, and another interface located in the upper detection hole 64 to detect whether the water level in the mixing tank 6 is too high. The pressure sensor detects the internal pressure of the mixing tank 6, thereby controlling the input of gas and liquid to ensure that the pressure in the mixing tank 6 is stable within the set range.
[0042] In use, the liquid output from the high-pressure pump 5 is atomized through the atomizing nozzle and then introduced into the mixing tank 6 to mix with the gas inside the mixing tank 6. The pressure inside the mixing tank 6 is increased by continuously introducing gas or simultaneously introducing liquid and gas, thereby ensuring the high solubility of the mixed gas in the liquid.
[0043] Reference Figures 1 to 6 An embodiment of the hydrogen-rich solution preparation device of this utility model is proposed:
[0044] A hydrogen-rich solution preparation device includes a housing 1, a control panel 3, a water tank 4, a gas-liquid mixing mechanism, a liquid dispensing mechanism 2, and a control circuit board.
[0045] Water tank 4, control circuit board and gas-liquid mixing mechanism are set inside housing 1, liquid outlet mechanism 2 and control panel 3 are set on the front side of housing, and liquid outlet mechanism 2 is set on the lower side of control panel 3.
[0046] The gas-liquid mixing mechanism includes a mixing tank 6, a water level sensor 7, an emptying pipe, a pressure sensor, a liquid input device, an atomizing device, and a gas input device.
[0047] In this embodiment, the liquid input device is a high-pressure pump 5, the gas input device is a gas generator 8, and the atomizing device is an atomizing nozzle.
[0048] The mixing tank 6 has an air inlet 63 on the bottom side of its side, and two detection holes 64 of different heights on the other side of the mixing tank 6 opposite to the air inlet 63. The mixing tank 6 has a liquid outlet 62 at the bottom and two liquid inlets 61 at the top.
[0049] The input end of the high-pressure pump 5 is connected to the water tank 4, and the output end of the high-pressure pump 5 is connected to the atomizing nozzle. The atomizing nozzle is connected to the liquid inlet 61 of the mixing tank 6. The water in the water tank 4 is pressurized by the high-pressure pump 5 and then input into the mixing tank 6 through the liquid inlet 61.
[0050] The water level sensor 7 has one interface located in the lower detection hole 64 to detect whether the water level in the mixing tank 6 is insufficient, and another interface located in the upper detection hole 64 to detect whether the water level in the mixing tank 6 is too high. The pressure sensor detects the internal pressure of the mixing tank 6, thereby controlling the input of gas and liquid to ensure that the pressure in the mixing tank 6 is stable within the set range.
[0051] The liquid outlet 62 of the tank is connected to the liquid outlet mechanism 2 through an output solenoid valve. The mixed hydrogen-rich solution is output through the liquid outlet mechanism 2. The liquid outlet 62 of the tank is also connected to the drain pipe through a drain solenoid valve.
[0052] The control circuit board is electrically connected to the high-pressure pump 5, the gas generator 8, the water level sensor 7, the pressure sensor, the output solenoid valve, the vent solenoid valve, and the control panel 3. The control panel 3 controls the working status of the high-pressure pump 5, the output solenoid valve, the vent solenoid valve, and the gas generator 8 through the control circuit board.
[0053] When in use, the user selects to make a hydrogen-rich solution through the control panel 3, the control circuit board controls the venting solenoid valve to open, and hydrogen is input through the gas generator 8. Since the density of hydrogen is less than that of air, it can vent the air from the liquid outlet 62 at the bottom of the tank through the venting pipe until the set venting time is reached, after which the venting solenoid valve closes.
[0054] After purging, water from tank 4 is pumped into the atomizing nozzle and then into mixing tank 6 via high-pressure pump 5. The pump continues until the liquid level in mixing tank 6 is above the lower detection port 64. At this point, the control circuit board detects the pressure inside mixing tank 6 via a pressure sensor. If the pressure inside mixing tank 6 is lower than a set threshold, the pressure inside mixing tank 6 is increased by either pumping hydrogen from gas generator 8 or simultaneously pumping water from high-pressure pump 5, until the pressure inside mixing tank 6 reaches the set threshold. Since the solubility of the hydrogen-rich solution is primarily determined by pressure, the hydrogen-rich solution prepared at this stage can be considered to meet the design requirements.
[0055] After successful preparation, the user will be notified via control panel 3. The user can then select water output via control panel 3, and the control circuit board will activate the output solenoid valve to output the hydrogen-rich solution to the outside through the liquid outlet mechanism 2. If the pressure inside the mixing tank 6 is insufficient after output, water from water tank 4 will be pumped into the atomizing nozzle and then into the mixing tank 6 via high-pressure pump 5 until the liquid level in the mixing tank 6 is higher than the detection hole 64 on the lower side. Then, hydrogen will be pumped in via gas generator 8, or hydrogen will be pumped in via gas generator 8 while water is pumped in via high-pressure pump 5, to increase the pressure inside the mixing tank 6 until the pressure inside the mixing tank 6 reaches the set threshold. This ensures that the pressure inside the mixing tank 6 is maintained within the set threshold.

Any equivalent structural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
