Description

Technical Field

[0001] This invention relates to the field of hydrogen-rich water cup technology, and more specifically to an integrated insulated hydrogen-rich water cup. Background Technology

[0002] This invention belongs to the interdisciplinary field of daily-use appliances and water treatment technology, specifically relating to an integrated electrolytic hydrogen-generating portable thermos cup based on solid polymer electrolytes. With the popularization of health-conscious consumption, portable water cups integrating hydrogen-rich water production functions have become a market hotspot. Existing technologies mainly involve integrating an electrolysis module inside the water cup to electrolyze water, generating hydrogen gas which dissolves in the water to form hydrogen-rich water. These products typically employ a separate or non-compact design, simply combining the electrolysis components with the cup body structure to achieve basic hydrogen production functionality; however, the overall integration is insufficient, making it difficult to operate stably in a wide temperature range.

[0003] Current hydrogen-rich water cups on the market suffer from significant deficiencies in structural design, user experience, and safety. Firstly, their internal structures are often disassembled, resulting in poor integration between the electrolysis module and the cup body. This not only affects the product's structural strength and aesthetics but also limits its adaptability to hydrogen production in both hot and cold water environments. Secondly, their gas management and safety systems are weak: the disposal of oxygen, a byproduct of electrolysis, is inadequate. Traditional designs often feature simplistic oxygen emission channels, pressure balancing measures, and safety redundancy for manual user intervention, leading to potential leaks or pressure surges. Furthermore, the user experience is poor. The layout of power controls, status displays, and charging ports is not efficiently integrated with the cup's ergonomic design, resulting in cumbersome operation and insufficient reliability.

[0004] In summary, existing technologies lack systematic solutions for structural compatibility, safety redundancy, and scenario adaptability, failing to meet users' demands for high-quality, safe, convenient, and healthy drinking water appliances. The industry urgently needs a solution that deeply integrates efficient electrolytic hydrogen production, long-lasting heat preservation, multiple safety pressure relief mechanisms, and intelligent human-machine interaction to overcome the aforementioned technical bottlenecks and provide a clear direction for the improvement of this invention. Summary of the Invention

[0005] In view of this, the present invention provides an integrated insulated hydrogen-rich water cup.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: The device includes a cup body with a handle and a lid. The cup body has a double-layer vacuum structure. An upper hydrogen-generating module is housed within the cup body. The upper hydrogen-generating module has an installation opening. An upper hydrogen-generating silicone ring, an upper hydrogen-generating titanium sheet, and a lower hydrogen-generating titanium sheet are sequentially arranged within the installation opening. A hydrogen-generating ion membrane is disposed between the upper and lower hydrogen-generating titanium sheets. A lower hydrogen-generating silicone ring is located below the lower hydrogen-generating titanium sheet. A hydrogen-generating module silicone ring is located below the lower hydrogen-generating silicone ring. The lower hydrogen-generating module is installed below the hydrogen-generating module silicone ring via hydrogen-generating fixing screws.

[0007] Furthermore, the cup handle includes an inner handle bracket mounted on the outer wall of the cup body, an outer handle bracket mounted on the inner handle bracket, and a display control panel embedded in the outer handle bracket.

[0008] Furthermore, the display control panel is provided with a display screen lens, the outer bracket of the handle is provided with a power button, the power button is electrically connected to the display control panel, a button decorative ring and a button silicone ring are installed around the circumference of the power button, the outer bracket of the handle is provided with a handle outer cover plate, and the handle outer cover plate is provided with a charging hole.

[0009] Furthermore, the silicone ring of the hydrogen production module is fixed to the upper hydrogen production module by a nut of the hydrogen production module insert. An oxygen discharge silicone plug is provided on the silicone ring of the hydrogen production module, and an oxygen discharge silicone tube is connected to the oxygen discharge silicone plug.

[0010] Furthermore, a circuit board bracket is mounted on the hydrogen production module via circuit board mounting screws, a control circuit board is mounted on the circuit board bracket, and circuit board electrode hardware is electrically connected to the control circuit board.

[0011] Furthermore, a battery mounting bracket is fixedly installed on the circuit board support, a storage battery is installed on the battery mounting bracket, a battery EVA foam is provided between the storage battery and the battery mounting bracket, a water cup bottom shell is installed on the battery mounting bracket, the storage battery is located between the water cup bottom shell and the battery mounting bracket, and a bottom shell waterproof pad is provided at the bottom of the water cup bottom shell.

[0012] Furthermore, the cup lid and the cup body are connected by threads. The cup lid is provided with a water outlet, which is connected to the inner cavity of the cup body. The cup lid is provided with a flip-top that is adapted to seal the water outlet. The cup lid is provided with an opening switch for opening the flip-top, which is engaged with the flip-top. A straw is provided on the water outlet, with one end of the straw connected to the inner cavity of the cup body and the other end of the straw connected to the water outlet.

[0013] Furthermore, the cup lid and the cup cap are hinged together by a hinged metal shaft, and a hinged spring is provided on the hinged metal shaft.

[0014] Furthermore, the cup lid is provided with an automatic venting top post inside, and the cup lid is provided with a venting hole, which is connected to the inner cavity of the cup. The automatic venting top post is provided with an automatic venting spring, and the automatic venting spring is provided with an automatic venting pressure plate.

[0015] Furthermore, the battery is electrically connected to the display control panel, the charging port, and the control circuit board.

[0016] Compared with existing technologies, it has the following positive effects: A dedicated oxygen venting channel is incorporated to direct the oxygen byproducts generated during electrolysis out of the cup, achieving hydrogen-oxygen separation and helping to maintain the concentration of hydrogen-rich water. Secondly, a pressure relief mechanism (automatic venting pin, spring, pressure plate, and vent hole) is integrated into the cup lid. When the pressure inside the cup becomes excessively high due to temperature changes or unexpected circumstances, this mechanism automatically opens to release pressure, providing passive safety redundancy and effectively preventing potential leaks or pressure surges, thus enhancing product safety.

[0017] The cup body integrates core electrolysis components such as the upper hydrogen production module, hydrogen production ion membrane, and lower hydrogen production titanium sheet, along with sealing components such as the upper / lower hydrogen production silicone rings and the lower hydrogen production silicone ring, into the installation opening through components such as the upper hydrogen production module, lower hydrogen production module, hydrogen production fixing screws, and insert nuts. This forms an integrated architecture of "electrolysis components - sealing structure - cup body", replacing the traditional separate splicing and improving the structural integration and strength.

[0018] The hydrogen production module is equipped with multiple layers of silicone rings (top silicone ring for hydrogen production, silicone ring for the hydrogen production module), a sealing structure for the water outlet of the cup lid, and a waterproof gasket on the bottom shell to achieve isolation and sealing between the hydrogen production area and the heat preservation area. This ensures the heat preservation effect (reducing heat loss) and avoids sealing failure in cold and hot water environments, thereby improving the adaptability of hydrogen production in a wide temperature range (cold / hot water).

Detailed Implementation

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example 1 like Figure 1-4 As shown in the figure, this embodiment details the specific structure, assembly relationship and working principle of the hydrogen production-related components in this invention. This part is the core functional module for hydrogen-rich water preparation, and its structural design directly determines the hydrogen production efficiency, gas separation effect and operational stability.

[0024] The cup body 1 has a double-layer vacuum insulation structure with a pre-reserved cavity for the hydrogen production module. The upper hydrogen production module 2 is fixed in this cavity by interference fit, ensuring a tight fit between the hydrogen production module and the insulation structure of the cup body 1, balancing insulation performance and hydrogen production stability. The top of the upper hydrogen production module 2 has an installation opening 3, the inner diameter of which matches the outer diameter of the upper hydrogen production silicone ring 4, the upper hydrogen production titanium sheet 5, and the lower hydrogen production titanium sheet 6, achieving a sealed assembly.

[0025] First, the upper silicone ring 4 for hydrogen generation is embedded into the inner stepped surface of the mounting opening 3, with its outer ring tightly fitting against the inner wall of the mounting opening 3, providing an initial seal. Then, the upper titanium sheet 5 for hydrogen generation is laid flat above the upper silicone ring 4. The upper titanium sheet 5 is a microporous titanium plate with good conductivity and hydrophilicity. Next, the hydrogen ion membrane 7 is placed over the upper surface of the upper titanium sheet 5. The surface of the hydrogen ion membrane 7 is coated with a catalyst coating to achieve selective hydrogen ion permeation and catalysis of the electrolysis reaction. A lower titanium sheet 6 for hydrogen generation is positioned above the hydrogen ion membrane 7, with a structure identical to the upper titanium sheet 5, forming a symmetrical electrode structure. A lower silicone ring 8 for hydrogen generation is laid below the lower titanium sheet 6, with clearance holes on its surface adapted to the electrode leads, ensuring sealing performance without affecting circuit connection. A silicone ring 9 for the hydrogen generation module is installed below the lower silicone ring 8, with a sealed cross-section.

[0026] The lower hydrogen production module 11 is fixedly connected to the silicone ring 9 of the hydrogen production module by the hydrogen production fixing screw 10, ensuring that the components of each layer fit tightly and form a sealed electrolysis chamber. The upper hydrogen production module 2 and the silicone ring 9 of the hydrogen production module are further reinforced by the hydrogen production module insert nut 21. The hydrogen production module insert nut 21 is embedded in the reserved hole of the upper hydrogen production module 2 to prevent the components from loosening due to pressure changes during electrolysis.

[0027] The hydrogen production module has an oxygen discharge hole on its silicone ring 9. An oxygen discharge silicone plug 22 is installed at this hole. The plug is made of medical-grade silicone, which is resistant to acids and alkalis and has high-temperature resistance. Its inner diameter is press-fitted with the outer diameter of the oxygen discharge silicone tube 23 to ensure a leak-proof seal. The oxygen discharge silicone tube 23 is a food-grade transparent silicone tube, with its other end extending to an exhaust port outside the cup body 1. Oxygen generated by electrolysis is discharged directionally to the outside through this tube, preventing it from mixing with hydrogen and affecting the concentration of the hydrogen-rich water.

[0028] The circuit board bracket 25 is fixed to the reserved mounting surface of the hydrogen production module 11 by circuit board mounting screws 24, providing good insulation and structural strength. A control circuit board 26 is fixedly mounted on the circuit board bracket 25, integrating an electrolysis drive chip, a power management module, and protection circuitry. Circuit board electrode hardware 27 is soldered onto the control circuit board 26. The circuit board electrode hardware 27 is made of a material with excellent conductivity and has an anti-corrosion treatment. The circuit board electrode hardware 27 is soldered and fixed to the electrode pads of the control circuit board 26 to ensure stable current transmission.

[0029] When the control circuit board 26 is connected to the battery 31, a DC voltage is applied to the upper titanium plate 5 (anode) and lower titanium plate 6 (cathode) of the hydrogen production module through the circuit board electrode hardware 27. Water in the electrolysis chamber undergoes an electrolytic reaction under the action of the electrodes and catalyst. Oxygen and hydrogen ions are produced at the anode. Oxygen is discharged from the cup 1 through the oxygen discharge silicone tube 23 on the silicone ring 9 of the hydrogen production module. Hydrogen ions migrate to the cathode through the selective permeation of the hydrogen ion membrane 7, combine with electrons to generate hydrogen gas, and the hydrogen gas directly dissolves into the water in the cup 1, forming hydrogen-rich water. This structure can operate stably under various water temperature conditions, and its hydrogen production efficiency is significantly higher than that of ordinary hydrogen-rich water cups.

[0030] Example 2 This embodiment details the remaining core structures other than the hydrogen production module, including the overall structure of the cup body 1, the human-computer interaction structure of the cup handle, the cup lid 43, and other structures.

[0031] The cup body 1 is vacuum-formed, providing excellent heat retention and maintaining water temperature for an extended period. The cup handle includes an inner handle bracket 12 and an outer handle bracket 13, both of which are fixed to a pre-reserved mounting position on the outer wall of the cup body 1 by screws.

[0032] A display control panel 14 is embedded in the middle of the outer support 13 of the handle. The display control panel 14 is equipped with a display screen lens 15 for displaying the concentration of hydrogen-rich water, water temperature, battery power 31, and working status. A power button 16 is provided on the outer support 13 of the handle, and the power button 16 is electrically connected to the button pad of the display control panel 14 via a flexible ribbon cable. A button decorative ring 17 and a button silicone ring 18 are fitted around the circumference of the power button 16. The button silicone ring 18 is embedded in the gap between the power button 16 and the outer support 13 of the handle to achieve a high level of waterproof sealing.

[0033] The outer cover plate 19 of the handle is fixed to the outer side of the handle outer bracket 13. The handle outer cover plate 19 has a charging hole 20, and a waterproof plug is installed at the interface. It cooperates with the button silicone ring 18 to achieve overall waterproofing of the handle area. The display control panel 14 and the control circuit board 26 are electrically connected through a flexible ribbon cable to realize command transmission and status feedback.

[0034] The hydrogen production module 11 is equipped with a circuit board bracket 25 via circuit board mounting screws 24. A battery mounting bracket 28 is fixed to the circuit board bracket 25. The mounting bracket is made of plastic and has an internal slot for mounting batteries 31. The inner wall of the slot is lined with EVA foam 29 for cushioning the batteries 31 during movement and also for insulation. The batteries 31 consist of two lithium batteries connected in series, and their surfaces are covered with an insulating protective film to prevent short circuits. Below the battery mounting bracket 28, a water cup bottom shell 30 is installed. The bottom shell is injection molded from engineering plastic, and a waterproof pad 32 is attached to its bottom to prevent water from entering the bottom of the cup and damaging the batteries 31 and the circuitry. The batteries 31 are located between the water cup bottom shell 30 and the battery mounting bracket 28, and are fixed to the power interface of the control circuit board 26 via wires. Insulating protective components are fitted onto the wires.

[0035] The cup lid 43 is threadedly connected to the cup body 1, and a food-grade sealing layer is provided on the threaded surface to ensure sealing performance. A water outlet 33 is provided at the top of the cup lid 43, directly communicating with the inner cavity of the cup body 1. A straw 36 is fixed to the water outlet 33 by a food-grade silicone sealing ring. One end of the straw 36 extends to the bottom of the cup body 1, ensuring normal drinking even when the water level is low. The other end of the straw 36 is connected to the water outlet 33. A flip-top lid 34 is hinged to the cup lid 43 via a flip-top hardware shaft 37, and a flip-top spring 38 is fitted onto the hinge. An opening switch 35 is provided on the cup lid 43, which cooperates with the snap-fit ​​structure of the flip-top lid 34. When the opening switch 35 is pressed, the snap-fit ​​unlocks, and the flip-top lid 34 automatically pops open under the elastic force of the flip-top spring 38, allowing the user to drink through the straw 36. When closing, pressing the flip-top lid 34 automatically locks the snap-fit, ensuring a seal.

[0036] An automatic venting top post 39 is installed at the center of the inside of the cup lid 43, with its top corresponding to the vent hole 40 of the cup lid 43. The vent hole 40 communicates with the inner cavity of the cup body 1. An automatic venting spring 41 is fitted onto the automatic venting top post 39, and an automatic venting pressure plate 42 is located below the automatic venting top post 39, which fits against the inner sealing surface of the cup lid 43. When the gas pressure inside the cup body 1 exceeds a preset safety threshold, the gas pressure overcomes the elastic force of the automatic venting spring 41, pushing the automatic venting pressure plate 42 and the automatic venting top post 39 to move, opening the vent hole 40 and achieving automatic pressure relief. When the gas pressure drops to a safe range, the spring returns to its original position, and the pressure plate reseals the vent hole 40 to prevent hydrogen leakage. This structure, together with the manual pressure relief function (pressure relief linked to the lid opening switch 35), forms a double safety guarantee, completely eliminating the risk of pressure explosion.

[0037] After assembly, the cup body 1 is reasonably sized for easy portability. The display control panel 14 shows the hydrogen-rich water concentration, remaining battery power, water temperature, and working status in real time. Users can easily start / stop the hydrogen production function using the power button 16. The straw 36 is designed for sports activities, allowing users to open the lid with one hand during exercise and continuously replenish hydrogen-rich water through the straw 36 without spilling. The high-level waterproof structure ensures that the product can be used in complex environments such as rain and splashes. The battery 31 can support long-term continuous hydrogen production on a single charge, meeting the needs of long-term outdoor use.

Similar or identical parts between embodiments can be referred to interchangeably. The above description of the disclosed embodiments enables those skilled in the art to make or use the invention.
