Description

Technical Field

[0001] The gas-liquid mixing of the present application relates to the technical field, and in particular to a gas-liquid mixing device for mixing hydrogen into liquid skin care products. Background Art

[0002] Hydrogen is a reducing gas, which plays roles such as antioxidant, anti-inflammatory and anti-apoptosis on the skin health of the human body. Therefore, hydrogen is widely used in the fields of beauty and skin care. By mixing hydrogen into liquid skin care products, a rich hydrogen-rich solution is formed. When people use liquid skin care products, the hydrogen-rich solution can gently stimulate the skin, massage the skin, promote skin blood circulation, deeply clean the skin and enhance the skin's ability to absorb nutrients. And when preparing hydrogen-rich liquid skin care products, a gas-liquid mixing device is needed to mix the liquid with hydrogen.

[0003] Chinese Patent with publication number CN209576361U discloses a gas-liquid mixing device, which includes a mixing body and a diverter. The diverter includes a gas-liquid mixing chamber inside it and convex ribs on its whole body. The two ends of the diverter are conical. Gas and liquid enter the gas-liquid mixing device through the input end and are output from the output end after passing through the diverter. This gas-liquid mixing device makes the input liquid more dispersed through the convex ribs arranged on the whole body of the diverter, increases the collision and mixing between hydrogen and the liquid, and improves the gas dissolution amount in the liquid.

[0004] However, after hydrogen is introduced into this gas-liquid mixing device, most of the hydrogen flows on the side close to the input end, the distribution of hydrogen in the gas-liquid mixing chamber is uneven, and the contact range between hydrogen and the liquid in the gas-liquid mixing chamber becomes smaller, resulting in insufficient mixing between hydrogen and the liquid, and the hydrogen dissolution rate in the liquid becomes smaller, which has obvious deficiencies. Summary of the Utility Model

[0005] In order to improve the solubility of hydrogen in liquid skin care products, the present application provides a gas-liquid mixing device for mixing hydrogen into liquid skin care products.

[0006] The gas-liquid mixing device for mixing hydrogen into liquid skin care products provided by the present application adopts the following technical solutions:

[0007] A gas-liquid mixing device for mixing hydrogen into liquid skin care products, comprising a housing. Inside the housing, a hydrogen production component, a hydrogen pipeline, and a gas-liquid mixing chamber are sequentially arranged. An air inlet is provided on the gas-liquid mixing chamber. The hydrogen production component is communicated with the air inlet through the hydrogen pipeline. An annular groove communicated with the air inlet is provided on the inner side wall of the gas-liquid mixing chamber. A baffle is rotatably connected in the annular groove. The outer surface of the baffle is closely attached to the inner side wall of the annular groove. An air outlet is provided on the baffle. A motor is arranged on the gas-liquid mixing chamber. The output shaft of the motor is fixedly connected with a bracket, and the bracket is fixedly connected with the baffle.

[0008] By adopting the above technical solution, when preparing hydrogen, the operator starts the motor. The motor drives the baffle to rotate in the annular groove. At the same time, the hydrogen prepared by the hydrogen production component flows into the annular groove through the air inlet. Under the rotation of the baffle, the air outlet on the baffle moves along the inner peripheral surface of the gas-liquid mixing chamber, so that hydrogen can enter the inside of the gas-liquid mixing chamber from all directions of the gas-liquid mixing chamber. The hydrogen flows evenly into the gas-liquid mixing interior, and the contact area between the hydrogen and the liquid in the gas-liquid mixing chamber becomes larger, so that the solubility of hydrogen in the liquid becomes higher.

[0009] Optionally, a rotating shaft is rotatably connected in the gas-liquid mixing chamber. The rotating shaft is fixedly connected with the output shaft of the motor. A spiral plate is arranged on the rotating shaft, and the spiral plate extends along the length direction of the rotating shaft.

[0010] By adopting the above technical solution, during the rotation of the motor, the motor drives the rotating shaft to rotate, and the rotating shaft drives the spiral plate to rotate. The rotating spiral plate guides the hydrogen-water mixture into a rotating fluid, and the turbulence degree of the hydrogen-water mixture increases. At the same time, the setting of the spiral plate extends the flow path of the hydrogen-water mixture, so that hydrogen and liquid can be fully mixed in the gas-liquid mixing chamber, and the solubility of hydrogen in the liquid is further improved.

[0011] Optionally, a flow dividing plate is arranged at one end of the gas-liquid mixing chamber away from the air inlet. The flow dividing plate is fixedly connected to the inner side wall of the gas-liquid mixing chamber. A plurality of water passing holes are provided on the flow dividing plate, and the length direction of the water passing holes is parallel to the length direction of the gas-liquid mixing chamber.

[0012] By adopting the above technical solution, when the hydrogen-water mixture passing through the spiral plate flows to the flow dividing plate, it is blocked by the volume of the flow dividing plate. At this time, the hydrogen-water mixture can only flow out through the water passing holes. The setting of the flow dividing plate evenly divides the hydrogen-water mixture into multiple paths for transportation, making the hydrogen-water mixture more dispersed. At the same time, the small opening diameter of the water passing holes can break the bubbles in the hydrogen-water mixture into finer bubbles, thereby further improving the solubility of hydrogen in the liquid.

[0013] Optionally, a baffle plate is fixedly connected to the rotating shaft. The bottom surface of the baffle plate is closely attached to the surface of the flow dividing plate. The baffle plate is rotatably connected to the inner side wall of the gas-liquid mixing chamber. A plurality of water outlet holes are formed in the baffle plate, and the water outlet holes and the water passing holes are arranged in a staggered manner.

[0014] By adopting the above technical solution, during the rotation of the motor, the rotating shaft drives the baffle plate to rotate. Under the baffle effect of the baffle plate, the hydrogen-water mixture will not directly flow out from the water passing holes. When the water outlet holes on the baffle plate are aligned with the water passing holes on the flow dividing plate, the hydrogen-water mixture flows out along the water outlet holes and the water passing holes. The setting of the baffle plate slows down the flow rate of the hydrogen-water mixture, thereby prolonging the flow time of the hydrogen-water mixture at the spiral plate, extending the mixing time of the hydrogen-water mixture, and increasing the solubility of hydrogen in the liquid.

[0015] Optionally, the hydrogen production assembly includes a water tank and an electrolytic cell. A water outlet pipe and an air inlet pipe are communicated with the water tank. The electrolytic cell is provided with a water inlet, a hydrogen outlet, and an oxygen outlet. The water inlet is communicated with the inside of the water tank through the water outlet pipe. The oxygen outlet is communicated with the inside of the water tank through the air inlet pipe. The hydrogen outlet is communicated with the air inlet through the hydrogen pipeline.

[0016] By adopting the above technical solution, when the electrolytic cell prepares hydrogen, the water in the water tank flows along the water outlet pipe into the electrolytic cell. The electrolytic cell electrolyzes water into hydrogen, oxygen, and water. Among them, oxygen and most of the water flow back into the water tank along the air inlet pipe, reducing the loss of water resources. Hydrogen and a small part of the liquid flow into the gas-liquid mixing chamber along the hydrogen pipeline.

[0017] Optionally, a gas-liquid separator is arranged inside the housing. The gas-liquid separator is arranged between the electrolytic cell and the gas-liquid mixing chamber. The liquid inlet of the gas-liquid separator is communicated with the inside of the electrolytic cell through the hydrogen pipeline. The gas outlet of the gas-liquid separator is communicated with the air inlet of the gas-liquid mixing chamber through the hydrogen pipeline.

[0018] By adopting the above technical solution, the hydrogen flowing out from the hydrogen outlet carries part of the water. If the water directly enters the inside of the gas-liquid mixing chamber along the hydrogen pipeline, it will cause the hydrogen concentration in the liquid in the gas-liquid mixing chamber to decrease. By setting the gas-liquid separator, the hydrogen is separated by the gas-liquid separation component before flowing into the gas-liquid mixing chamber, thereby reducing the water content in the hydrogen pipeline, increasing the hydrogen concentration in the hydrogen pipeline, and thus increasing the solubility of hydrogen in the liquid.

[0019] Optionally, an electric control box is arranged inside the housing. A storage battery and a controller are sequentially arranged inside the electric control box. A flow sensor is arranged inside the gas-liquid mixing chamber. A solenoid valve is arranged on the water outlet pipe. Both the flow sensor and the solenoid valve are electrically connected to the controller through a control system.

[0020] By adopting the above technical solution, the flow sensor measures the flow data of the skin care product liquid. The controller receives the flow data to adjust the opening degree of the solenoid valve, thereby adjusting the speed of the water flowing from the water tank into the electrolytic cell, and thus adjusting the hydrogen production speed of the electrolytic cell, reducing the occurrence of the phenomenon that the hydrogen production speed of the electrolytic cell is too slow to be fully mixed in the skin care product liquid.

[0021] Optionally, a maintenance door is arranged on the outer surface of the housing.

[0022] By adopting the above technical solution, when the solubility of hydrogen decreases or other problems occur, workers can repair the gas-liquid mixing device by opening the maintenance door, thereby ensuring the normal operation of the gas-liquid mixing process.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. In the present application, by providing an annular groove, a baffle plate and an air outlet, the baffle plate rotates in the annular groove to make the air outlet move along the inner peripheral surface of the gas-liquid mixing chamber, so that hydrogen can enter the inside of the gas-liquid mixing chamber from all directions of the gas-liquid mixing chamber. The hydrogen flows uniformly into the inside of the gas-liquid mixing, and the contact area between the hydrogen and the liquid in the gas-liquid mixing chamber becomes larger, so that the solubility of hydrogen in the liquid becomes higher;

[0025] 2. In the present application, by providing a baffle plate and a flow dividing plate, the flow dividing plate divides the hydrogen-water mixture evenly into multiple paths for transportation, making the hydrogen-water mixture more dispersed. The baffle plate makes the flow rate of the hydrogen-water mixture slower, so that the flow time of the hydrogen-water mixture at the spiral plate is extended, the mixing time of the hydrogen-water mixture is extended, and the solubility of hydrogen in the liquid is increased.

[0031] The following further elaborates on this application Figures 1-4 in conjunction with the attached drawings.

[0032] An embodiment of this application discloses a gas-liquid mixing device for mixing hydrogen into liquid skin care products.

[0033] Referring to Figure 1 and Figure 2 , a gas-liquid mixing device for mixing hydrogen into liquid skin care products includes a housing 1. An access door is provided on the housing 1. When the solubility of hydrogen decreases or other problems occur, workers can perform maintenance on the gas-liquid mixing device by opening the access door, thereby ensuring the normal operation of the gas-liquid mixing process.

[0034] Referring to Figure 1 and Figure 2 , inside the housing 1, a hydrogen production assembly 2, a gas-liquid separator 3 and a gas-liquid mixing chamber 4 are sequentially installed. The hydrogen production assembly 2 includes a water tank 21 and an electrolyzer 22 fixedly installed in the housing 1. The water tank 21 stores water for hydrogen production. A water outlet pipe 211 and an air inlet pipe 212 are installed on the water tank 21. An inlet 221, a hydrogen outlet 222 and an oxygen outlet 223 are installed on the outer surface of the electrolyzer 22. Among them, the water inlet 221 is internally connected to the water tank 21 through the water outlet pipe 211, the oxygen outlet 223 is internally connected to the water tank 21 through the air inlet pipe 212, a hydrogen pipeline 5 is connected to the hydrogen outlet 222, the liquid inlet of the gas-liquid mixing chamber 4 is internally connected to the electrolyzer 22 through the hydrogen pipeline 5, an air inlet 41 is provided at one end of the gas-liquid mixing chamber 4 close to the gas-liquid separator 3, and the gas outlet 711 of the gas-liquid separator 3 is connected to the air inlet 41 of the gas-liquid mixing chamber 4 through the hydrogen pipeline 5.

[0035] Referring to Figure 1 and Figure 2, an electric control box 6 is fixedly installed inside the housing 1. The electric control box 6 is arranged directly above the hydrogen production assembly 2 and the gas-liquid separator 3. Inside the electric control box 6, a storage battery 61 for supplying power to the electrolytic cell 22 and a controller 62 are sequentially installed. An electromagnetic valve 63 is installed on the water outlet pipe 211, and the electromagnetic valve 63 is electrically connected to the controller 62 through a control system.

[0036] When hydrogen needs to be produced, the control system controls the electromagnetic valve 63 to open, and the water in the water tank 21 flows into the electrolytic cell 22. The electrolytic cell 22 electrolyzes water into hydrogen, oxygen and water. Among them, oxygen and most of the water flow back into the interior of the water tank 21 along the air inlet pipe 212, reducing the loss of water resources. Hydrogen and a small part of the liquid flow into the gas-liquid separator 3 along the hydrogen pipeline 5. After passing through the separation of the gas-liquid separator 3, the concentration of hydrogen flowing out of the gas-liquid separator 3 increases, thereby increasing the concentration of hydrogen entering the gas-liquid mixing chamber 4, and further increasing the solubility of hydrogen in the gas-liquid mixing chamber 4.

[0037] Refer to Figure 2 , Figure 3 and Figure 4 , one end of the gas-liquid mixing chamber 4 is connected and installed with a liquid inlet pipe 42, and the other end is connected and installed with a liquid outlet pipe 43. The skin care product liquid flows into the gas-liquid mixing chamber 4 from the liquid inlet. The skin care product liquid mixed with hydrogen flows out from the liquid outlet. An annular groove 7 communicating with the air inlet 41 is opened on the inner side wall of the gas-liquid mixing chamber 4. A baffle 71 is rotatably connected in the annular groove 7. The outer surface of the baffle 71 is in close fit with the inner side wall of the annular groove 7. The baffle 71 is annular and both opposite ends of the baffle 71 are fixedly connected with sliders (not shown in the figure). Sliding grooves (not shown in the figure) for interacting with the sliders are opened on the opposite inner side walls of the annular groove 7. The baffle 71 is slidably connected in the annular groove 7. An air outlet 711 communicating with the annular groove 7 is opened on the baffle 71. A motor 8 is fixedly installed on the top surface of the gas-liquid mixing chamber 4. The output shaft of the motor 8 is fixedly connected with a bracket 81. The baffle 71 is fixedly connected to the outer surface of the bracket 81.

[0038] When producing hydrogen, the operator starts the motor 8. The motor 8 drives the baffle 71 to rotate in the annular groove 7. At the same time, the hydrogen produced by the hydrogen production assembly 2 flows into the annular groove 7 through the air inlet 41. Under the movement of the baffle 71, the air outlet 711 on the baffle 71 moves along the inner peripheral surface of the gas-liquid mixing chamber 4, so that hydrogen can enter the interior of the gas-liquid mixing chamber 4 from all directions of the gas-liquid mixing chamber 4. Hydrogen flows evenly into the gas-liquid mixing interior, and the contact area between hydrogen and the liquid in the gas-liquid mixing chamber 4 becomes larger, so that the solubility of hydrogen in the liquid becomes higher.

[0039] Refer to Figure 2 , Figure 3 and Figure 4, the output shaft of the motor 8 is coaxially and fixedly connected to a rotating shaft 9. A spiral plate 10 is fixedly connected to the outer surface of the rotating shaft 9. The spiral plate 10 extends along the length direction of the rotating shaft 9. One end of the rotating shaft 9 away from the bracket 81 is fixedly connected to a baffle plate 11. The baffle plate 11 is rotatably connected inside the gas-liquid mixing chamber 4. A plurality of water outlet holes 111 are formed in the baffle plate 11. The length direction of the water outlet holes 111 is parallel to the length direction of the gas-liquid mixing chamber 4. A flow dividing plate 12 is arranged below the baffle plate 11. The flow dividing plate 12 includes being fixedly installed inside the gas-liquid mixing chamber 4. The surface of the flow dividing plate 12 is closely attached to the bottom surface of the baffle plate 11. A plurality of water passing holes 121 are formed in the flow dividing plate 12. The water passing holes 121 and the water outlet holes 111 are staggered and arranged.

[0040] During the rotation of the motor 8, the rotation of the motor 8 drives the rotation of the rotating shaft 9, and the rotation of the rotating shaft 9 drives the rotation of the spiral plate 10. The rotating spiral plate 10 guides the hydrogen-water mixture into a rotating fluid, increasing the turbulence degree of the hydrogen-water mixture. At the same time, the setting of the spiral plate 10 extends the flow path of the hydrogen-water mixture, enabling hydrogen and liquid to be fully mixed in the gas-liquid mixing chamber 4. While the rotating shaft 9 rotates, it drives the baffle plate 11 to rotate. When the water outlet holes 111 on the baffle plate 11 are aligned with the water passing holes 121 on the flow dividing plate 12, the hydrogen-water mixture flows out along the water outlet holes 111 and the water passing holes 121. The setting of the baffle plate 11 slows down the flow rate of the hydrogen-water mixture, thereby prolonging the mixing time of the hydrogen-water mixture. At the same time, under the flow dividing action of the flow dividing plate 12, the hydrogen-water mixture is evenly divided into multiple paths for transportation, making the hydrogen-water mixture more dispersed. At the same time, the small opening diameter of the water passing holes 121 can break up the bubbles in the hydrogen-water mixture into finer bubbles, thereby further increasing the solubility of hydrogen in the liquid.

[0041] Refer to Figure 2 , Figure 3 and Figure 4 , in order to ensure the full mixing of hydrogen and skin care product liquid, a flow sensor 64 is fixedly installed on the inner side wall of the gas mixing chamber close to the bracket 81. The flow sensor 64 is electrically connected to the controller 62 through a control system.

[0042] The flow sensor 64 measures the flow data of the skin care product liquid. The controller 62 receives the flow data to adjust the opening degree of the solenoid valve 63, thereby adjusting the speed of water flowing from the water tank 21 into the electrolytic cell 22, and thus adjusting the hydrogen production speed of the electrolytic cell 22, reducing the occurrence of the phenomenon that the hydrogen production speed of the electrolytic cell 22 is too slow to be fully mixed in the skin care product liquid.

[0043] The implementation principle of a gas-liquid mixing device for mixing hydrogen into liquid skin care products in an embodiment of the present application is as follows: When preparing hydrogen, the hydrogen prepared by the electrolytic cell 22 first passes through the gas-liquid separator 3, and after separation, it enters the annular groove 7 along the hydrogen pipeline 5. At the same time, the motor 8 is started, and the motor 8 drives the baffle 71 to rotate in the annular groove 7. Under the rotation of the baffle 71, the air outlet 711 on the baffle 71 moves along the inner peripheral surface of the gas-liquid mixing chamber 4, so that hydrogen can enter the inside of the gas-liquid mixing chamber 4 from all directions of the gas-liquid mixing chamber 4. The hydrogen flows evenly into the gas-liquid mixing interior, and the contact area between the hydrogen and the liquid in the gas-liquid mixing chamber 4 becomes larger, so that the solubility of hydrogen in the liquid becomes higher;

[0044] While the motor 8 rotates, it drives the baffle 11 to rotate on the surface of the flow dividing plate 12. When the water outlet hole 111 on the baffle 11 is aligned with the water passing hole 121 on the flow dividing plate 12, the hydrogen-water mixture flows to the liquid outlet pipe 43 along the water outlet hole 111 and the water passing hole 121, and finally flows out from the liquid outlet pipe 43.

[0045] The above are all the preferred embodiments of the present application. Without limiting the protection scope of the present application accordingly, therefore: All equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
