Description

Technical Field

[0001] This utility model relates to the field of hydrogen-rich solution manufacturing technology, specifically a hydrogen-rich device that can achieve efficient hydrogen enrichment for different beverages. Background Technology

[0002] Existing hydrogen-rich water is water containing hydrogen molecules. Its functions and effects are the same as ordinary water, generally including promoting digestion, maintaining electrolyte balance, excreting waste, keeping the body adequately hydrated, and regulating body temperature. With the further development of related technologies, hydrogen-rich devices are also moving towards miniaturization and portability. For example, the hydrogen-rich water cup disclosed in the prior art can use the principle of electrolysis of water to produce hydrogen in the cup through a small electrolyzer device, thereby achieving the effect of automatic hydrogen enrichment.

[0003] However, the existing method of directly electrolyzing drinking water with hydrogen-rich water cups cannot meet the hydrogen enrichment requirements of different beverages, and many problems will occur when electrolyzing non-pure water beverages, such as the electrodes being corroded by the components in the beverage, which shortens their service life, and the beverage components undergoing chemical reactions during the electrolysis process, which leads to changes in taste and nutritional components, etc. Therefore, in order to solve the shortcomings of the above-mentioned existing technologies, the applicant will provide a hydrogen enrichment device that can achieve efficient hydrogen enrichment of different beverages. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a hydrogen-rich device capable of efficiently enriching different beverages with hydrogen, thus solving the problems mentioned in the background section.

[0005] This utility model provides the following technical solution: a hydrogen-rich device that can achieve efficient hydrogen enrichment for different beverages, including a cup body, a cup lid and a cup base respectively installed on the top and bottom of the cup body, an electrolytic cell assembly installed inside the cup base, the output structure of the electrolytic cell assembly communicating with the internal space of the cup body and being able to deliver hydrogen into the cup body by electrolysis, and a polytetrafluoroethylene membrane assembly for separating the internal space of the cup body is provided between the cup body and the electrolytic cell assembly;

[0006] The polytetrafluoroethylene (PTFE) membrane assembly includes an internally threaded ring plate, an externally threaded ring plate, and a PTFE membrane. The PTFE membrane is fixedly fitted inside the externally threaded ring plate and forms a filter channel inside the cup body. The internally threaded ring plate is fixedly fitted inside the bottom of the cup body. The externally threaded ring plate is threadedly connected to the inside of the internally threaded ring plate, and a torsion bar is nested inside the bottom of the externally threaded ring plate.

[0008] Preferably, the electrolytic cell assembly includes a base, on the top of which are respectively mounted an electrolytic cell component, a power supply module, a controller, and a positioning sleeve. The electrolytic cell component includes an electrolytic cell shell and an electrode module. The electrolytic cell shell is made of a corrosion-resistant material. An electrolytic diaphragm is fitted inside the electrolytic cell shell, and the electrolytic diaphragm is located in the middle inner side of the electrolytic cell shell, dividing the internal space of the electrolytic cell shell into a hydrogen production space and an oxygen production space. The electrode module includes an anode plate and a cathode plate. One end of the anode plate and one end of the cathode plate are respectively fitted into the oxygen production space and the hydrogen production space. The other ends of the anode plate and the other ends of the cathode plate extend to the outside of the electrolytic cell shell and are electrically connected to the controller and the power supply module respectively through wires.

[0009] Selectedly, the controller includes a display screen, a microcontroller, and a switch. A transparent observation plate aligned with the display screen is nested on the inner wall of the front end of the cup holder. A rubber button capable of adjusting the pressure of the switch is installed inside the transparent observation plate for convenient direct control of the controller. The positioning sleeve is fixedly nested on the top inner side of the cup holder. Two elastic transition hoses are installed inside the positioning sleeve. One end of each of the two elastic transition hoses serves as the output structure of the electrolyzer assembly and is respectively installed inside the top of the oxygen production space and the top of the hydrogen production space.

[0010] The cup holder features a stepped groove on its inner side at the bottom, with a threaded hole in the middle inner wall of the groove. The base has a countersunk hole aligned with the threaded hole. The base is snapped into the stepped groove and is coplanar. The base can be detachably installed and removed from the cup holder by screwing it into the countersunk hole and then screwing it into the threaded hole, facilitating subsequent maintenance or replacement of damaged parts. A charging recess is provided on one side of the cup holder. The power supply module includes a rechargeable battery, and a USB charging port fitted into the charging recess is installed on one side of the rechargeable battery to ensure continuous use.

[0011] The cup lid features an inverted conical hole at its top that communicates with its own space. A filter component and a pressure relief valve component are housed inside the inverted conical hole. The pressure relief valve component is located above the filter component. The filter component consists of a support ring and a protective filter screen nested within the support ring. The support ring is fixedly fitted inside the bottom of the inverted conical hole. The filter component prevents subsequent beverage particles from entering the inverted conical hole from inside the cup, thus optimizing the usage effect.

The annular guide frame is fixedly sleeved on the inner side of the middle of the inverted conical hole, and the middle part of the I-shaped rod is engaged with the inner side of the middle of the annular guide frame. The two ends of the return spring are fixedly connected to the bottom surface of the I-shaped rod and the bottom surface of the annular guide frame, respectively. The top of the I-shaped rod is engaged with the inner side of the top of the inverted conical hole and can seal the internal space of the inverted conical hole. Subsequently, when the pressure inside the cup is too high, the pressure relief valve component will move to release the pressure and ensure safe use.

[0013] Preferably, the top surface of the I-shaped rod is nested with an auxiliary sealing ring. The surface of the auxiliary sealing ring is in close contact with the inner wall of the top of the inverted conical hole and can seal and fill the gap between the top of the I-shaped rod and the top of the inverted conical hole, thereby improving the sealing fit effect of the pressure relief valve component with the inverted conical hole.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model uses a polytetrafluoroethylene (PTFE) diaphragm assembly as a separation condition. When used in combination with the cup body, cup lid, cup base, and electrolytic cell assembly, the PTFE diaphragm assembly can effectively separate water from the electrolyte inside the electrolytic cell assembly. This allows for safe and efficient hydrogen-rich treatment of various beverages. Furthermore, due to the barrier effect of the PTFE membrane inside the PTFE diaphragm assembly, impurities generated by the electrolyte and electrode reactions will not enter the beverage, thus ensuring the original ingredients and taste of the beverage.

[0016] 2. This utility model uses an inverted conical hole inside the cup lid, along with a filter component and a pressure relief valve component, to form a pressure relief device. When the pressure inside the cup increases to a certain level, excess gas will pass through the filter component to press against the pressure relief valve component, causing the movable structure inside the pressure relief valve component to automatically move out of place inside the inverted conical hole. This allows the excess gas inside the cup to be released through the inverted conical hole, maintaining the pressure inside the cup within a reasonable range and ensuring the reliability and safety of the overall equipment operation.

[0033] Please see Figures 1-11 A hydrogen-rich device capable of efficiently enriching different beverages with hydrogen includes a cup body 1, a cup lid 2 and a cup base 3 respectively installed on the top and bottom of the cup body 1. External threads are provided on the surface of the top port and the surface of the bottom port of the cup body 1.

The bottom inner side of the cup lid 2 and the top inner side of the cup base 3 are threadedly connected to the outer side of the top port of the cup body 1 and the outer side of the bottom port of the cup body 1, respectively.

[0034] An electrolytic cell assembly 4 is housed within the cup holder 3.

The electrolytic cell assembly 4 includes a base 41, and an electrolytic cell component 42, a power supply module, a controller 44, and a positioning sleeve 45 are respectively installed on the top of the base 41. The electrolytic cell component 42 includes an electrolytic cell shell 421 and an electrode module. The electrolytic cell shell 421 is made of corrosion-resistant material, and an electrolytic diaphragm 422 is installed inside the electrolytic cell shell 421. The diaphragm 422 is located on the inner side of the middle part of the electrolytic cell shell 421 and divides the internal space of the electrolytic cell shell 421 into a hydrogen production space and an oxygen production space. The electrode module includes an anode plate 423 and a cathode plate 424.

The other ends of the anode plate 423 and the cathode plate 424 extend to the outside of the electrolytic cell shell 421 and are electrically connected to the controller 44 and the power supply module respectively through wires.

[0035] The controller 44 includes a display screen, a microcontroller, and a switch. A transparent observation plate aligned with the display screen is nested on the inner wall of the front end of the cup holder 3. Inside the transparent observation plate is a rubber button that can adjust the pressure of the switch, facilitating direct control of the controller 44. A positioning sleeve 45 is fixedly nested inside the top of the cup holder 3. Two flexible transition hoses 47 are installed inside the positioning sleeve 45. One end of each flexible transition hose 47 serves as the output structure of the electrolyzer assembly 4, respectively fitted inside the top of the oxygen production space and the top of the hydrogen production space.

The PTFE membrane assembly 5 includes an internally threaded ring plate 51, an externally threaded ring plate 52, and a PTFE membrane 53. The PTFE membrane 53 is fixedly fitted inside the externally threaded ring plate 52 and forms a filter channel inside the cup body 1. The internally threaded ring plate 51 is fixedly fitted inside the bottom of the cup body 1. The externally threaded ring plate 52 is threadedly connected to the inside of the internally threaded ring plate 51, and a torsion bar 54 is nested inside the bottom of the externally threaded ring plate 52.

[0037] Specific usage of this embodiment:

[0038] Pure water is first added into the interior of the electrolysis tank housing 421 through two flexible transition hoses 47, thus serving as the electrolyte. Next, the bottom outer structure of the cup body 1 is screwed into the top inner structure of the cup base 3. After completion, the beverage to be used is added into the cup body 1. Under the barrier of the polytetrafluoroethylene membrane 53 inside the polytetrafluoroethylene diaphragm assembly 5, the beverage to be used and the pure water electrolyte are in an independent state without contact. After completion, the bottom inner structure of the cup lid 2 is screwed into the top outer structure of the cup body 1.

[0039] After the entire device is assembled, press the rubber button on the front of the cup holder 3 to activate the setting inside the controller 44. At the same time, the controller 44 controls the rechargeable battery 43 to supply power to the anode plate 423 and cathode plate 424. The anode plate 423 and cathode plate 424, together with the electrolytic diaphragm 422, electrolyze the pure water electrolyte inside the electrolytic cell shell 421 to produce hydrogen. Then, the oxygen produced in the oxygen production space and the hydrogen produced in the hydrogen production space will enter the bottom area of ​​the polytetrafluoroethylene diaphragm assembly 5 through two elastic transition hoses 47. Then, the hydrogen and oxygen diffuse through the micropores inside the polytetrafluoroethylene membrane 53 into the beverage stored inside the cup body 1, so that the hydrogen dissolves in the beverage, enriching the beverage with hydrogen to meet the usage requirements. At the same time, due to the barrier effect of the polytetrafluoroethylene membrane 53, impurities generated by the electrolyte and electrode reaction will not enter the beverage, thus ensuring the original ingredients and taste of the beverage.

[0040] Please see 11- Figure 14 The top of the cup lid 2 has an inverted conical hole 6 that communicates with its own space. Inside the inverted conical hole 6, there is a filter component 7 and a pressure relief valve component 8. The pressure relief valve component 8 is located above the filter component 7. The filter component 7 consists of a support ring and a protective filter screen nested inside the support ring. The support ring is fixedly fitted to the bottom inside of the inverted conical hole 6. The filter component 7 is used to prevent subsequent beverage particles inside the cup body 1 from entering the interior of the inverted conical hole 6, thus optimizing the usage effect.

[0041] The pressure relief valve component 8 includes an annular guide frame 81, an I-shaped rod 82, and a return spring 83. The annular guide frame 81 is fixedly sleeved on the inner side of the middle of the inverted conical hole 6, and the middle part of the I-shaped rod 82 is engaged with the inner side of the middle of the annular guide frame 81. The two ends of the return spring 83 are fixedly connected to the bottom surface of the I-shaped rod 82 and the bottom surface of the annular guide frame 81, respectively. The top of the I-shaped rod 82 is engaged with the inner side of the top of the inverted conical hole 6 and can seal the internal space of the inverted conical hole 6. When the pressure inside the cup body 1 is too high, the pressure relief valve component 8 will move to release the pressure and ensure safe use.

[0042] An auxiliary sealing ring 84 is nested on the top surface of the I-shaped rod 82. The surface of the auxiliary sealing ring 84 fits and connects with the inner wall of the top of the inverted conical hole 6 and can seal and fill the gap between the top of the I-shaped rod 82 and the top of the inverted conical hole 6, thereby improving the sealing fit effect of the pressure relief valve component 8 on the inverted conical hole 6.

[0043] Specific usage of this embodiment:

[0044] As hydrogen continuously enters the beverage at the top of the cup body 1, the pressure inside the cup body 1 gradually increases. When the pressure increases to a certain level, the excess gas will pass through the filter component 7 to press against the I-shaped rod 82 inside the pressure relief valve component 8. This causes the I-shaped rod 82 to move passively upward under the guidance of the annular guide frame 81. At the same time, the return spring 83 is in a stretched state, thereby making room for the top of the inverted conical hole 6. Then, the excess gas inside the cup body 1 will be released through the inverted conical hole 6, thereby maintaining the pressure inside the cup body 1 within a reasonable range and ensuring the reliability and safety of the overall equipment operation.

[0045] When the rotating device or the entire device needs to be moved for a long time, in order to prevent the beverage inside the cup 1 from leaking due to shaking during the movement, the top of the I-shaped rod 82 can be pressed during the movement.
