Description

Technical Field

[0001] This utility model relates to the field of hydrogen production equipment technology, and in particular to a portable hydrogen absorption machine based on the hydrolysis of solid hydrogen production materials. Background Technology

[0002] Hydrogen inhalation machines, as devices that produce hydrogen for users to inhale, have broad application prospects in health care, medical assistance, and other fields. Currently, most mainstream hydrogen inhalation machines use the water electrolysis method to produce hydrogen: water is continuously electrolyzed in an electrolyzer to produce hydrogen, which is then separated into gas and liquid and dried before being inhaled by the user.

[0003] However, existing hydrogen absorption machines have the following drawbacks in practical applications:

[0004] Disadvantage 1: The mechanical structure is complex, and it generally adopts a multi-stage series connection of "water tank → water pump → electrolytic cell → gas-liquid separator → humidification bottle". It has many parts, large size, and long pipelines, making it inconvenient to carry. The number of water / air leakage points increases exponentially, and an additional water pump is required to maintain the flow rate, resulting in high energy consumption and noise.

[0005] Second shortcoming: The gas pathway cannot achieve "breathing synchronization". The hydrogen output is in a continuous and constant mode, and the amount of gas produced is much greater than the demand for a single inhalation. The hydrogen produced during the exhalation phase is directly discharged into the environment, resulting in hydrogen waste.

[0006] Disadvantage 3: Difficult heat dissipation. The electrolysis process continuously releases heat, and traditional fans or heat sinks have limited heat dissipation capacity. After long-term operation, the water temperature rises, which not only reduces electrolysis efficiency but also brings the risk of burns. Utility Model Content

[0007] This invention mainly addresses the technical problems of existing technologies, such as hydrogen waste, high temperature rise, complex structure, and inconvenience in carrying. Based on the advantages of hydrogen production by hydrolysis of solid hydrogen production materials, such as high safety, high hydrogen storage density, and easy portability, this invention proposes a portable hydrogen absorption machine based on the hydrolysis of solid hydrogen production materials. This machine is characterized by its small size, simple structure, portability, on-demand production, low temperature rise, and safe use.

[0008] This utility model provides a portable hydrogen absorption machine based on the hydrolysis of solid hydrogen production materials, including: a tank, a reaction module disposed in the tank, and a hydrogen storage module;

[0009] The reaction module includes: a reaction chamber, a water chamber, and hydrogen production materials;

[0010] A water tank is installed inside the reaction chamber, and a valve is installed at the bottom of the water tank; a gap is left between the water tank and the inner wall of the reaction chamber; hydrogen production material is placed at the bottom of the reaction chamber, and the hydrogen production material is placed below the water tank.

[0011] The hydrogen storage module includes: a storage chamber, connecting components, and a suction channel;

[0012] The bottom of the gas storage chamber is sealed to the top of the reaction chamber via a connecting component; a hydrogen channel is provided in the middle of the connecting component; the inlet of the hydrogen channel is connected to the reaction chamber, and the outlet is connected to the gas storage chamber; an air intake channel is provided above the gas storage chamber.

[0013] Preferably, one side of the gas storage chamber is connected to an air intake pipe, and a one-way valve is installed on the air intake pipe.

[0014] Preferably, a hydrogen concentration sensor is provided on the intake channel.

[0015] Preferably, the hydrogen production material includes an active material and a reaction aid;

[0016] The active material includes active metal materials or metal hydride materials;

[0017] The reaction aid is a mild acid.

[0018] Preferably, the connecting component is a threaded connector, a clamp connector, or an O-ring sealing connector.

[0019] Preferably, an OLED screen is provided on the outer wall of the tank.

[0020] This invention provides a portable hydrogen absorption machine based on the hydrolysis of solid hydrogen production materials, which has the following advantages compared with the prior art:

[0021] 1. When the hydrogen absorption machine starts operating, water is supplied only once. The hydrogen-producing material comes into contact with the water and undergoes a chemical reaction to produce hydrogen gas. Since there is no need for continuous water pumping, the temperature rise is low, fundamentally eliminating the risks of "overheating-dry burning-scalding" and achieving on-demand production and safe use.

[0022] 2. Utilizing the physiological cycle of human inhalation (approximately 2-4 seconds) and exhalation (approximately 2-4 seconds), the hydrogen produced by the continuous hydrolysis of the hydrogen-producing material is temporarily stored in the gas storage chamber. During inhalation, a hydrogen production amount of 4-8 seconds is absorbed at once. During exhalation, the gas storage chamber temporarily stores hydrogen, and during inhalation, it is used instantly, realizing a continuous cycle of stopping production without stopping extraction.

[0023] 3. The entire machine eliminates the electrolyzer, water pump, and cooling fan, employing a reaction module and a hydrogen storage module. It features a simple structure, light weight, small size, and easy portability. The hydrogen production reaction originates from the reaction process of the hydrogen-producing material, resulting in low temperature rise, zero electrolysis components, fewer additional parts, and lower cost. It achieves "portable, instant hydrogen production, and predictable dosage." This invention allows for convenient replacement of the hydrogen-producing material and easy hydrogen absorption.

[0026] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.

[0027] like Figure 1 As shown in the figure, the present invention provides a portable hydrogen absorption machine based on the hydrolysis of solid hydrogen production materials, comprising: a tank, a reaction module disposed in the tank, and a hydrogen storage module.

[0028] The reaction module includes a reaction chamber 1, a water tank 3, and a hydrogen production material 2. The reaction chamber 1 serves as the reaction site. The water tank 3 is located within the reaction chamber 1, and a valve 4 is installed at the bottom of the water tank 3. The valve 4 can be an automatic solenoid valve or a manual valve. A gap is left between the water tank 3 and the inner wall of the reaction chamber 1 to allow hydrogen gas to pass through. The hydrogen production material 2 is placed at the bottom of the reaction chamber 1, positioned below the water tank 3. Opening the valve 4 releases the liquid water from the water tank 3, which then comes into contact with the hydrogen production material 2, causing a reaction that produces hydrogen gas, which flows upwards in the form of bubbles.

[0029] The hydrogen production material 2 includes an active material and a reaction aid. The active material includes an active metal or a metal hydride. Active metals include magnesium and aluminum, while metal hydrides include aluminum hydride, magnesium hydride, and calcium hydride, and are available in powder or granular form. The reaction aid is a mild acid, such as acetic acid, citric acid, or lactic acid, and can be available in powder or granular form, or prepared as a solution. Solid hydrogen production material 2 can be pre-placed in reaction chamber 1. Before hydrogen absorption, water chamber 3 can be opened, and water or an acid solution can be added to begin hydrogen production. Alternatively, water or an acid solution can be pre-stored in reaction chamber 1, and solid hydrogen production material 2 can be added before hydrogen absorption to begin hydrogen production.

[0030] The hydrogen storage module includes a storage chamber 7, a connecting component 5, and a suction channel 9. The bottom of the storage chamber 7 is sealed to the top of the reaction chamber 1 via the connecting component 5. The connecting component 5 is used to achieve a sealed connection between the reaction chamber 1 and the storage chamber 7. The connecting component 5 uses a threaded connector, a clamp connector, or an O-ring sealing connector, and is inserted and removed from the reaction chamber 1 and the storage chamber 7. A hydrogen channel 6 is provided in the middle of the connecting component 5. The inlet of the hydrogen channel 6 is connected to the reaction chamber 1, and the outlet is connected to the storage chamber 7. The suction channel 9 is provided above the storage chamber 7. The hydrogen generated by the reaction module enters the storage chamber 7 through the hydrogen channel 6 and is stored in the storage chamber 7.

[0031] One side of the gas storage chamber 7 is connected to an air inlet pipe 8, which is equipped with a one-way valve. When air is drawn in through the intake channel 9, air enters the gas storage chamber 7 through the air inlet pipe 8. A hydrogen concentration sensor 10 is installed on the intake channel 9. An OLED screen 11 is installed on the outer wall of the tank.

[0032] Hydrogen-generating material 2 in the reaction module undergoes hydrolysis, and the generated hydrogen gas is discharged along the intake channel 9. The hydrogen concentration sensor 10 on the intake channel 9 begins to operate normally. The hydrogen concentration sensor 10 is connected to the OLED screen 11 through a microcontroller and signal lines, transmitting the hydrogen concentration to the OLED screen 11 in real time. The microcontroller is used to receive analog or digital signals from the hydrogen concentration sensor 10 and convert them into a displayable format.

[0033] In addition, a water inlet and a feeding port are provided on the tank body. The water inlet is connected to the water tank 3, and is opened when water is added and sealed when in use. The feeding port is connected to the reaction chamber 1, and is opened when feeding materials and sealed when in use.

[0034] The working process of this utility model is as follows: A certain amount of magnesium hydride composite hydrogen-generating material 2 is placed inside the reaction chamber 1. After being loaded into the hydrogen absorption machine tank, valve 4 is opened, and water tank 3 immediately injects water into the reaction chamber 1, triggering hydrolysis to produce hydrogen. The resulting hydrogen is temporarily stored in the gas storage tank 7. When the user inhales, air is simultaneously mixed in through the air inlet pipe 8, and the hydrogen concentration sensor 10 detects the hydrogen concentration in real time. When 0.5 g of magnesium hydride composite hydrogen-generating material 2 is placed, the average volume concentration of hydrogen is ≥1% and the average flow rate is 15 ml / min within a 30-minute hydrogen absorption cycle, meeting the requirements for safe and continuous hydrogen absorption. After the user finishes hydrogen absorption, the reaction chamber containing the hydrogen-generating material 2 is disassembled and replaced, and the device enters standby mode.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications to the technical solutions described in the foregoing embodiments, or equivalent substitutions for some or all of the technical features, do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
