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

[0023] Example 1: Figure 1 This is a schematic diagram of the hydrogen generation reaction device according to an embodiment of the present invention.

[0024] Specifically, this utility model embodiment provides a hydrogen generation reaction device, including a liquid storage device, a reaction device, a first one-way valve 15, a second one-way valve 16, and an exhaust on / off valve 9.

[0025] Basically, the liquid storage device includes a liquid storage chamber 7, a passive piston 18, and an elastic element 6.

[0026] The liquid storage tank 7 has an internal liquid storage tank 17, and the passive piston 18 is slidably fitted inside the liquid storage tank 17 and divides the liquid storage tank 17 into a liquid tank 3 and a control tank 4; wherein, the liquid tank 3 is used to store liquid reactants that participate in the hydrogen production reaction.

[0027] The elastic element 6 is disposed inside the control chamber 4. One end of the elastic element 6 is connected to the passive piston 18, and the other end is free. When the elastic element 6 is compressed, the free end will press against the entity corresponding to its position.

[0028] The liquid storage tank 7 is provided with a first liquid storage interface 2 and a second liquid storage interface 1 that communicate with the liquid tank 3.

[0029] Basically, the reaction apparatus includes a generation chamber 13, which has an internal reaction chamber 12 and a first reaction interface 11, a second reaction interface 14 and an exhaust interface 10 communicating with the reaction chamber 12, wherein the reaction chamber 12 is used to store solid reactants participating in the hydrogen production reaction.

[0030] Basically, the first liquid storage interface 2 and the first reaction interface 11 are connected based on the first one-way valve 15, and the second liquid storage interface 1 and the second reaction interface 14 are connected based on the second one-way valve 16. The conduction direction of the first one-way valve 15 and the conduction direction of the second one-way valve 16 are opposite. In this embodiment of the present invention, the conduction direction of the first one-way valve 15 is from the first liquid storage interface 2 to the first reaction interface 11, and the conduction direction of the second one-way valve 16 is from the second reaction interface 14 to the second liquid storage interface 1.

[0031] Basically, the exhaust on / off valve 9 is located at the exhaust port 10 and is used for controlling the output and off of hydrogen.

[0032] In practical application, the hydrogen generation reactor is initially in a compressed state with the elastic element 6 in a closed state. The liquid chamber 3 stores a preset liquid reactant, and the reaction chamber 12 stores a preset solid reactant. The liquid chamber 3 and reaction chamber 12 are interconnected and reach a pressure equilibrium. When the exhaust valve 9 is opened, the elastic restoring force of the elastic element 6 drives the liquid reactant into the reaction chamber 12 through the first liquid storage port 2, the first one-way valve 15, and the first reaction port 11. The liquid and solid reactants react to generate hydrogen. Since the hydrogen discharge rate (or the rate at which the discharged hydrogen is consumed by the outside) through the exhaust valve 9 is relatively constant, the hydrogen generation in the reaction chamber 12 causes an increase in pressure. When the pressure equals the elastic restoring force of the elastic element 6, the shape recovery of the elastic element 6 is hindered. At this point, no more liquid reactant will be released. The liquid reactants enter the reaction chamber 12. When the hydrogen generation rate decreases due to problems such as the reduction of liquid reactants and the consumption of solid reactants (under the influence of gravity, the solid reactants in the lower layer will be consumed preferentially), the elastic restoring force of the elastic element 6 will drive more liquid reactants into the reaction chamber 12, thereby increasing the hydrogen generation rate until the gas pressure and the elastic restoring force of the elastic element 6 return to a balanced state. When the exhaust valve 9 is closed, the increase in gas pressure will cause the liquid reactants to flow back into the liquid chamber 3 through the second reaction port 14, the second one-way valve 16, and the second liquid storage port 1, and simultaneously compress the elastic element 6. When the liquid reactants and solid reactants are no longer in contact (since the solid reactants in the lower layer are consumed preferentially, the liquid reactants may not necessarily flow back completely), the reaction stops, hydrogen is no longer generated, and the hydrogen generation reaction device as a whole returns to a static state until the exhaust valve 9 is reopened.

[0033] Furthermore, the hydrogen generation reaction device also includes an active piston 5 and a piston drive component 8; The active piston 5 is disposed within the control chamber 4, and the elastic element 6 is disposed between the active piston 5 and the passive piston 18. One end of the piston drive element 8 is connected to the active piston 5, and the other end of the piston drive element 8 extends to the outside of the liquid storage tank 7. Under the drive of the piston drive element 8 and the active piston 5, initial pressure can be provided to the elastic element 6. For ease of operation, in an optional embodiment, the piston drive element 8 is threaded onto the liquid storage tank 7.

[0034] Example 2 Figure 2 This is a schematic diagram of the hydrogen generation reaction device according to an embodiment of the present invention.

[0035] Specifically, considering the convenience of practical application, both the liquid storage tank 7 and the generation tank 13 can be designed as consumables in actual implementation. Furthermore, based on Embodiment 1, the first one-way valve 15 and the second one-way valve 16 can be integrated into the connecting structure 19 to facilitate the connection and installation of the liquid storage tank 7 and the generation tank 13. Additionally, the exhaust on / off valve 9 can be integrated into the exhaust port.

[0036] Specifically, the hydrogen generation reaction device further includes an intermediate connection device, which includes a connection structure 19, on which the first one-way valve 15 and the second one-way valve 16 are integrated. The liquid storage tank 7 is movably connected to the connecting structure 19, and when the liquid storage tank 7 is fixedly connected to the connecting structure 19, the first liquid storage interface 2 is connected to the first one-way valve 15, and the second liquid storage interface 1 is connected to the second one-way valve 16. The generating chamber 13 is movably connected to the intermediate connecting device, and when the generating chamber 13 is fixedly connected to the connecting structure 19, the first reaction interface is connected to the first one-way valve 15, and the second reaction interface is connected to the second one-way valve 16.

[0037] Specifically, the movable connection between the liquid storage tank 7 and the connecting structure 19 can be a snap-fit ​​connection, and the movable connection between the generating tank 13 and the intermediate connecting device can be a snap-fit ​​connection.

[0038] Example 3 Figure 3 This is a schematic diagram of the hydrogen generation reaction device according to an embodiment of the present invention.

[0039] Specifically, considering the convenience of practical application, both the liquid storage tank 7 and the generating tank 13 can be designed as consumables in actual implementation. Correspondingly, based on Embodiment 1, the first one-way valve 15 is integrated into the liquid storage tank 7 or the generating tank 13; the first one-way valve 15 is integrated into the liquid storage tank 7 or the generating tank 13. Furthermore, the exhaust on / off valve 9 can be integrated into the exhaust port.

[0040] Furthermore, the liquid storage tank 7 is provided with a first mating connection structure, and the generating tank 13 is provided with a second mating connection structure; The first and second mating connection structures are designed to fit together. The liquid storage tank 7 and the generating tank 13 are integrally connected based on the first and second mating connection structures. According to this embodiment, the liquid storage tank 7 and the generating tank 13 can be interconnected without a third-party structure, significantly improving ease of use.

[0041] Optionally, the first mating connection structure and the second mating connection structure can be mating flange connection structures or snap-fit ​​structures.

[0042] Example 4 Specifically, when the liquid storage tank 7 and the generating tank 13 are both made of consumable materials, an optional embodiment is that the liquid storage tank 7 has a cylindrical structure, the liquid tank 3 is located below the control tank 4, and the first liquid storage interface 2 and the second liquid storage interface 1 are located on the bottom surface of the liquid storage tank 7. By grouping the interfaces involved in the reaction onto the same side of the tank, it facilitates the convenience of connection and use.

[0043] Accordingly, the generating chamber 13 has a cylindrical structure, the exhaust port 10 is disposed on the top surface of the generating chamber 13, and the first reaction port 11 and the second reaction port 14 are disposed on the bottom surface of the generating chamber 13.

[0044] In addition, if the liquid reactant is a non-polluting raw material, an injection port connected to the liquid tank 3 can be set on the liquid storage tank 7 to replenish the liquid reactant and realize the secondary use of the liquid storage tank 7.

[0045] Example 5 Figure 4 This is a schematic diagram of the hydrogen generation reaction device according to Embodiment 5 of this utility model.

[0046] Based on Embodiments 3 and 4, the first mating connection structure and the second mating connection structure are mutually mating external locking structures 25.

[0047] Specifically, the external locking structure 25 in this embodiment refers to a locking structure located outside the contact surface between the liquid storage tank 7 and the generating tank 13. Compared with the internal locking structure, the external locking structure 25 is easier to disengage, which is beneficial for the rapid replacement of consumables.

[0048] Example 6 Based on Embodiments 3 and 4, the first mating connection structure and the second mating connection structure are mutually mating built-in locking structures 26.

[0049] Figure 5 This is a schematic diagram of the hydrogen generation reaction device according to Embodiment Six of this utility model.

[0050] Specifically, the built-in locking structure 26 in this embodiment refers to a locking structure located inside the contact surface between the liquid storage tank 7 and the generating tank 13. Compared to an external locking structure, the built-in locking structure 26 has better anti-disengagement performance, which helps ensure the proper fit between the liquid storage tank 7 and the generating tank 13; in actual use, a certain amount of force is required to disengage the built-in locking structure 26.

[0051] It should be noted that the actual hydrogen production component in the hydrogen generation reactor provided in this embodiment is the generation chamber 13. If the hydrogen reaction rate is too fast, it is easy to generate high heat. To dissipate heat from the generation chamber, it can be directly immersed in water, and the hydrogen can be discharged through a gas pipe. Since the overall structure of the device is relatively closed, with only some reliable interface structures, directly immersing the generation chamber in water will not produce any additional adverse reactions. Regarding the quality of the generated hydrogen, on the one hand, since the hydrogen production reaction starts from the bottom of the reactor chamber, the generated hydrogen needs to pass through the solid reactants above, which can act as a desiccant to dry the hydrogen. If higher requirements are required for the produced hydrogen, it can be connected to a downstream hydrogen treatment device after the exhaust port 10. This embodiment of the invention will not provide further details.

[0052] In summary, this utility model provides a hydrogen generation reaction device with a relatively simple structure. It can spontaneously control the hydrogen reaction through pressure balance. Through its special structural design, it can quickly replace consumables in actual use and is adaptable to various application scenarios.

[0053] The above provides a detailed description of a hydrogen generation reaction device provided by the embodiments of this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
