Description

Technical Field

[0001] This utility model relates to hydrogen production technology, and more particularly to a portable hydrogen production and supply device based on solid hydrogen storage materials. Background Technology

[0002] Hydrogen is a colorless, odorless, and non-toxic small-molecule gas. With its selective antioxidant properties (such as scavenging toxic free radicals like ·OH and ONOO-) and anti-inflammatory properties (such as inhibiting cytokines like TNF-α and IL-1β), hydrogen shows significant potential in the intervention of chronic diseases. However, its clinical application has long been limited by the technological shortcomings of portable hydrogen supply devices—traditional methods such as electrolytic hydrogen production and high-pressure hydrogen storage cannot meet the safe, immediate, and controllable hydrogen intake needs in everyday scenarios.

[0003] To enable the immediate inhalation of hydrogen in everyday scenarios, developing portable hydrogen production and supply devices has become a key technological challenge. However, current hydrogen production devices designed for cigarette use have significant drawbacks: 1. The hydrogen production process is cumbersome—requiring multiple chemical reactions or relying on external energy sources for triggering; 2. Insufficient reactant stability—active materials (such as aluminum powder) are easily oxidized and deactivated, resulting in short storage periods; 3. High system complexity—byproduct cleanup and catalyst addition increase maintenance burden. These problems severely restrict the ease of use and reliability of the devices, hindering the practical application of the health benefits of hydrogen molecules. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned problems by proposing a portable hydrogen production and supply device based on solid hydrogen storage materials. This device achieves on-demand hydrogen production through the stable and efficient hydrolysis reaction of metal hydrides (such as magnesium hydride). It can be seamlessly adapted to ordinary smoking, menthol cigarettes, or pure air hydrogen inhalation scenarios. While meeting the portable hydrogen supply needs of multiple scenarios, it effectively reduces the intake of harmful substances through multiple pre-filter materials.

[0005] It should be noted that, in this utility model, unless otherwise specified, the specific meaning of "comprising" in relation to composition and description includes both open-ended meanings such as "comprising," "including," etc., and closed-ended meanings such as "composed of," "consisting of," etc., and similar meanings.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a portable hydrogen production and supply device based on solid hydrogen storage material, comprising a tubular body, wherein the tubular body comprises a sequentially connected inhalation section, a hydrogen production section and a nozzle section, and the hydrogen production section is filled with solid hydrogen storage material.

[0007] Furthermore, a filtration section is provided between the inhalation section and the hydrogen production section, and the filtration section is filled with a filter element. That is, the tubular body includes an inhalation section, a filtration section, a hydrogen production section, and a nozzle section that run in sequence.

[0008] The inhalation section is used to introduce a moisture-containing airflow, which can be humidified air or smoke produced by cigarette combustion. Typically, the moisture content in the smoke is about 11-13%.

[0009] Furthermore, the inner diameter of the inhalation section matches the outer diameter of the cigarette (cigarette filter), allowing the cigarette to be inserted. Specifically, a cigarette filter can be inserted into the inhalation section. The cigarette is a regular cigarette or a cigarette with a built-in flavor capsule in the filter, and the flavor capsule contains water.

[0010] Furthermore, the inner wall of the inhalation section has a stepped constricted structure to accommodate and position cigarettes of different thicknesses.

[0011] Furthermore, the inner wall of the stepped constricted structure of the suction section can be achieved by a positioning ring fixed inside the suction section, the outer diameter of which matches the inner diameter of the suction section.

[0012] The filtration section is located downstream of the inhalation section and is filled with a filter element. It can filter harmful substances carried in smoke or air and release a certain amount of beneficial components.

[0013] Furthermore, the filter element includes filter cotton and a porous baffle structure, with filter media filling the space between the filter cotton and the porous baffle structure. The filter cotton is provided at one end of the filter element near the hydrogen production section, and the porous baffle structure is provided at the other end near the intake section.

[0014] Furthermore, the filter material is traditional Chinese medicine, magnetic beads, activated carbon, or maifan stone.

[0015] Furthermore, the porous baffle structure is gear-shaped, and multiple through holes are formed between the porous baffle structure and the inner wall of the tubular main body. The porous baffle structure cooperates with the stepped necking structure (also known as the stepped positioning structure) to achieve its own positioning.

[0016] The hydrogen production section is located downstream of the filtration section and is filled with solid hydrogen storage material. Its function is to utilize the moisture carried in the gas stream (flue gas or air) to react with the solid hydrogen storage material through a hydrolysis reaction, thereby producing hydrogen. Different hydrogen production methods (such as humidified air absorption or smoke extraction) result in varying hydrogen concentrations at the inlet due to differences in the moisture content carried in the gas stream. For example, when using humidified air absorption, the hydrogen concentration ranges from approximately 1 ppm to 100 ppm, and the higher the moisture content of the gas stream, the higher the hydrogen concentration.

[0017] Furthermore, the solid hydrogen storage material is a granular solid hydrogen storage material with a particle size greater than or equal to 0.5 mm.

[0018] Furthermore, the amount of the solid hydrogen storage material is 0.1g to 1.0g.

[0019] Furthermore, a filter cotton is provided at one end of the solid hydrogen storage material near the nozzle section, or filter cotton is provided at both ends of the hydrogen storage material. The filter cotton effectively prevents the hydrogen storage material or product debris from flowing out of the hydrogen production section while positioning the hydrogen storage material. The filter cotton placed at the end (near the nozzle section) is positioned by a protrusion in the inner cavity of the tubular main body.

[0020] Furthermore, the solid hydrogen storage material is a metal hydride.

[0021] Furthermore, the solid hydrogen storage material is preferably one or more of calcium hydride, magnesium hydride, aluminum hydride, and titanium hydride.

[0022] Furthermore, the chemical reaction equation for the hydrogen production by hydrolysis of the metal hydride is as follows:

[0023] MH n +nH₂O→M(OH) n +nH2↑

[0024] When the metal hydride is magnesium hydride, the chemical reaction equation for its hydrolysis to produce hydrogen is:

[0025] MgH2 + 2H2O → Mg(OH)2 + 2H2↑

[0026] Furthermore, the hydrogen storage material also includes granulation additives and / or catalysts.

[0027] Furthermore, the amount of the granulation additive is 10% to 30% of the hydrogen storage material, and the granulation additive facilitates the granulation of metal hydrides.

[0028] Furthermore, the granulation additive is a food-grade binder, such as one or more of gelatin, starch, and paraffin.

[0029] The mouthpiece section is located downstream of the hydrogen production section and is the part that the user holds in their mouth.

[0030] Furthermore, the mouthpiece section has a flat or circular cross-section, conforming to ergonomic design, so as to facilitate sucking when put into the mouth.

[0031] The working principle of the portable hydrogen production and supply device based on solid hydrogen storage material described in this utility model is as follows:

[0032] 1) Start-up preparation: The device can be started using any of the following methods:

[0033] Position the inhalation section of the device by embedding a regular cigarette holder or a cigarette holder with a built-in flavor capsule;

[0034] Alternatively, the intake section of the device can be made to communicate only with humid air.

[0035] 2) User operation: The user puts the nozzle section of the device into their mouth.

[0036] 3) Inhalation Trigger and Hydrogen Production / Supply: When the user inhales through the mouthpiece, an airflow is generated. Depending on the activation method, this airflow includes:

[0037] The smoke produced by burning cigarettes;

[0038] Or, a mixture of air and the components of the popping beads;

[0039] Or, the smoke produced by burning cigarettes carries a mixture of flavor capsule components;

[0040] Or, simply humid air.

[0041] The airflow sequentially passes through the inhalation section, the filtration section, and the hydrogen production section, finally reaching the mouthpiece. When the airflow passes through the filtration section, and the filter material is made of traditional Chinese medicine, the airflow will carry certain components of the traditional Chinese medicine. When the airflow passes through the hydrogen production section, the moisture it contains (originating from flue gas, bead atomization, or ambient humidity) comes into full contact with the solid hydrogen storage material (metal hydride, such as magnesium hydride) and undergoes a hydrolysis reaction, generating hydrogen in real time.

[0042] 4) Mixed inhalation: The generated hydrogen gas is then mixed with the mainstream gas flowing through it and inhaled by the user.

[0043] This utility model presents a portable hydrogen production and supply device based on solid-state hydrogen storage materials, which has the following advantages compared with the prior art:

[0044] 1) The hydrogen production section of this portable hydrogen production and supply device based on solid hydrogen storage material is filled with solid hydrogen storage material, which is selected from metal hydrides (such as magnesium hydride). Metal hydrides are stable, easy to store, and have high hydrogen storage density and strong hydrogen production capacity, producing more hydrogen under the same mass conditions. This material produces hydrogen in one step through a hydrolysis reaction, which is simple and reliable.

[0045] 2) This device has a wide range of applications: it can be used in conjunction with the smoking process as a cigarette holder; it can be used alone with a cigarette holder containing a flavor capsule; it can also absorb hydrogen by using water vapor; and it can even produce and supply hydrogen using only water vapor in the air.

[0046] 3) When the portable hydrogen production and supply device based on solid hydrogen storage material of this invention is used in conjunction with the smoking process, the device combines the multiple filtration functions of existing cigarette holders. Its front end is equipped with multiple filter materials and beneficial components, which can effectively reduce the harmful substances inhaled during smoking.

[0047] 4) Specifically, the device can be used in the process of ordinary smoking, in conjunction with cigarettes containing menthol capsules, or independently, relying solely on water vapor in the air to produce and absorb hydrogen. Attached Figure Description
