Description

A hydrogen Chinese medicine co-inhalation atomization system based on hydrogen storage material hydrolysis and hydrogen release Technical Field

The present invention relates to the technical field of hydrogen production and health care, and in particular to a hydrogen traditional Chinese medicine co-inhalation atomization system, an atomizer and an atomization method based on the hydrolysis of hydrogen storage materials to release hydrogen.

Background Art

Hydrogen can selectively scavenge highly viral hydroxyl radicals and nitrite anions, while having little effect on other biologically important, less toxic reactive oxygen species. This means hydrogen exhibits a selective antioxidant effect. Hydrogen also has therapeutic benefits for inflammatory responses, with its direct reaction with hydroxyl radicals being the basis for its anti-inflammatory properties. Hydrogen can significantly inhibit inflammatory responses, reduce inflammatory factor levels, alleviate inflammatory pathological damage, and improve healing. Hydrogen's anti-inflammatory effects are related to its ability to inhibit reactive oxygen species production, neutralize hydroxyl radicals, and inhibit the release of proinflammatory factors. In summary, hydrogen's selective antioxidant, anti-inflammatory, and anti-apoptotic biological effects offer promising adjunctive therapeutic benefits for a variety of common human chronic diseases, including cardiovascular, endocrine, and metabolic, neurological, digestive, and respiratory diseases, and even tumors. Hydrogen inhalation is currently an important medical method for the human body to ingest hydrogen. However, existing hydrogen production and inhalation equipment is complex, costly, and inconvenient.

Inhalation therapy is an important and effective method for treating illnesses. A nebulizer atomizes liquid medication into tiny particles, which are then inhaled into the respiratory tract and deposited in the lungs, achieving painless, rapid, and effective treatment. Beyond treating illnesses, inhalation therapy is now also being used in healthcare.

Co-nebulization of hydrogen and traditional Chinese medicine can leverage their synergistic effects, achieving even more significant positive effects than hydrogen alone or through traditional Chinese medicine alone. Currently, inhaled hydrogen primarily comes from water electrolysis and hydrogen storage material release. Electrolysis equipment is complex, expensive, requires specialized personnel, and has a limited lifespan. Hydrogen storage material release facilitates the development and manufacture of portable hydrogen production devices. Hydrogen storage material release occurs through two methods: hydrolysis and thermal release. Invention CN115400301A discloses a hydrogen Chinese medicine co-inhalation atomization system and a nebulizer based on thermal hydrogen release of hydrogen storage materials. The nebulizer includes a shell, a power control system, a hydrogen Chinese medicine co-inhalation atomization system, a pneumatic induction counting switch and a filter nozzle; the power control device includes a battery and an integrated control circuit; the hydrogen Chinese medicine co-inhalation atomization system includes a hydrogen supply tank and a Chinese medicine atomization tank, and a heating system that allows thermal hydrogen release is provided inside the hydrogen supply tank. The hydrogen supply tank is arranged below the Chinese medicine atomization tank and is inverted with the Chinese medicine atomization tank; the power control system, the hydrogen Chinese medicine co-inhalation atomization system, the pneumatic induction counting switch and the filter nozzle are all arranged inside the shell; the integrated control circuit is respectively connected to the battery, the heating system, the pneumatic induction counting switch and the Chinese medicine atomization tank; the power supply is arranged below the integrated control circuit, the hydrogen supply tank is arranged above the integrated control circuit, the pneumatic induction counting switch is arranged between the hydrogen supply tank and the Chinese medicine atomization tank, and the filter nozzle is arranged at the top of the Chinese medicine atomization tank. This invention uses heat from a power source to pyrolyze magnesium hydride hydrogen storage material, providing hydrogen for an atomization device, enabling portable and controllable hydrogen absorption. However, due to the thermal hydrogen release method, hydrogen poses certain safety risks under high temperature conditions, hindering its practical application.

Invention CN109250683B discloses a hydrogen production device based on the hydrolysis of magnesium hydride as a hydrogen storage material to release hydrogen, including a reaction chamber in which a layer of blocky magnesium hydride filler is provided. The blocky magnesium hydride is in the form of granules or cakes. The blocky magnesium hydride is stacked in the reaction chamber, the gaps between the particles become larger, and the energy density of the filler increases, which is conducive to water vapor reaching all parts of the filler for full contact reaction and efficient hydrogen production. At the same time, hydrogen escapes more smoothly from the filler to prevent a sudden increase in pressure in the reaction chamber. This invention uses water vapor and magnesium hydride to hydrolyze to produce hydrogen. The controllability of the hydrogen production process is poor, and the reaction cannot be stopped after it is started. In addition, the device is complex and large, making it difficult to achieve portability and flexible use.

JP2009279241A discloses a hydrogen inhalation method and device. This device generates hydrogen by reacting an organic acid containing a carboxyl group with magnesium or magnesium hydride. The device also humidifies the hydrogen using the water vapor and heat generated by this reaction. While this device offers some portability and flexibility, its hydrogen production is low and uncontrollable, resulting in poor reusability, limited functionality, and high production and operating costs.

In summary, hydrogenation by hydrolysis of hydrogen storage materials is a safer method of hydrogen supply. However, how to provide a simple, convenient, and controllable hydrogen supply method based on the hydrolysis of hydrogen storage materials, with easy replacement of consumables, good portability, controllable process, and low production and use costs, and how to combine it with liquid atomization for co-inhalation, is an urgent problem to be solved by those skilled in the art.

Summary of the Invention

In response to the defects in the above-mentioned prior art, the present invention provides a hydrogen Chinese medicine co-absorption atomization system, an atomizer and an atomization method based on the hydrolysis and hydrogenation of hydrogen storage materials. The hydrogen Chinese medicine co-absorption atomization system is based on the hydrogen production process of the hydrolysis and hydrogenation of hydrogen storage materials. It has low energy consumption, safety and reliability, and the hydrogen production process is highly controllable. The atomizer has a simple and compact structure, consumables are easy to add and replace, the production and use costs are low, and the portability is good. The atomization absorption and hydrogen absorption of Chinese medicine liquid are completed at the same time.

In a first aspect, the present invention provides a hydrogen Chinese medicine co-inhalation atomization system based on the hydrolysis of hydrogen storage materials to release hydrogen, comprising a Chinese medicine liquid tank, an atomization unit, a multifunctional tank, a liquid capsule, an extrusion unit, and a control unit;

The Chinese medicine liquid tank includes a first opening connected to the external environment and a second opening connected to the multifunctional tank, and the atomization unit atomizes the Chinese medicine liquid in the Chinese medicine liquid tank;

The multifunctional chamber includes a medicine chamber for loading hydrogen storage materials and is connected to the liquid capsule;

The extrusion unit squeezes the liquid capsule to press the liquid in the liquid capsule into the multifunctional chamber to hydrolyze the hydrogen storage material and release hydrogen;

The control unit regulates the extrusion unit to control the hydrolysis and hydrogen release process of the hydrogen storage material.

Preferably, the atomization unit is an ultrasonic vibration plate, which is arranged on the side wall and/or bottom of the traditional Chinese medicine liquid tank; the medicine chamber is connected to the liquid capsule through a microporous tube, and the liquid in the liquid capsule is pressed into the medicine chamber through the microporous tube.

The use of ultrasonic vibration plates to atomize liquid medicine has the following advantages: the ultrasonic vibration plates can atomize the liquid medicine into fine particles, so that the liquid medicine can be quickly and evenly distributed in the target area, thereby improving the atomization efficiency; the ultrasonic vibration plate atomization equipment generally adopts a handheld design, which is simple and convenient to operate and can be easily carried and moved; the ultrasonic vibration plate does not produce harmful substances during the atomization process, and is safe and reliable to use, and is particularly suitable for patients who require long-term treatment; the ultrasonic vibration plate atomization equipment has a simple structure and is easy to maintain, and generally only requires regular cleaning and replacement of components such as the filter. The number of ultrasonic vibration plates used in the present invention can be one or more, which can fully atomize the liquid medicine in the traditional Chinese medicine liquid tank, and is preferably arranged at the bottom of the traditional Chinese medicine liquid tank, with low overall atomization energy consumption and good atomization uniformity.

Preferably, the multifunctional warehouse further comprises a buffer chamber located between the medicine chamber and the Chinese medicine liquid warehouse, and a microporous ceramic filter is provided between the buffer chamber and the Chinese medicine liquid warehouse.

The pore size of the microporous ceramic filter is 1-100 μm, preferably 5-50 μm, and more preferably 10-35 μm. It has the advantages of high mechanical strength, no harmful substances dissolving, and no secondary pollution. Under the action of fluid or gas pressure, the micropores do not deform. When the gas pressure accumulated in the buffer chamber reaches a threshold value, the gas enters the Chinese medicine liquid tank through the microporous ceramic, and is released from the first outlet of the Chinese medicine liquid tank to the external environment together with the atomized Chinese medicine liquid, providing hydrogen and Chinese medicine for co-absorption. When the control unit controls the extrusion unit to stop squeezing the liquid capsule, the hydrolysis reaction process of the hydrogen storage material stops, the pressure in the buffer chamber gradually decreases, and after reaching hydraulic equilibrium with the upper pressure, no hydrogen enters the Chinese medicine liquid tank. However, at this time, the device of the present invention can also be used only as a Chinese medicine liquid atomizer. At the same time, the effect of adjusting the hydrogen release rate can be achieved by controlling the micropore diameter; the microporous ceramic filter is easy to clean and regenerate when used in a portable atomizer, and has a long service life. In addition, the control unit can regulate the extrusion unit intermittently or continuously to obtain a variety of hydrogen storage material hydrolysis and hydrogenation processes.

Optionally, a heat-conducting material is provided on the top of the multifunctional chamber, especially the buffer chamber, to transfer the heat released by hydrolysis and hydrogen production to the Chinese medicine liquid tank, so that the temperature of the hydrogen and Chinese medicine co-inhalation mist is suitable, reducing irritation to the human respiratory system.

Preferably, the hydrogen storage material comprises a metal hydride, which is at least one of _MgH2 , _CaH2 , and _ZnH2 ; _MgH2 is the preferred material, and its amount preferably accounts for more than 93% of the total mass of the hydrogen storage material, but can also be adjusted accordingly according to actual conditions.

In addition, the hydrogen storage material preferably further comprises a promoter and/or a purifier;

The promoter is selected from LiOH, KOH, NaOH or citric acid, and its amount accounts for 0.5-2% of the total mass of the hydrogen storage material;

The purifier is selected from at least one of iron powder, nickel powder, cobalt powder and palladium powder, and its usage accounts for 1-5% of the total mass of the hydrogen storage material.

Magnesium hydride was chosen as the hydrogen storage material because it has a high hydrogen storage capacity per unit mass. Compared to other metal hydrogen storage materials, magnesium hydride is lightweight, making it easy to store and carry in an atomizer. Furthermore, magnesium hydride is relatively low-cost and reversible, making it easy and inexpensive to replace after long-term use. Adding a reaction accelerator to the hydrogen storage material can shorten the reaction start-up time, while adding a gas purifier can improve hydrogen quality.

Preferably, the extrusion unit comprises an extrusion piston, and the extrusion piston is driven by a motor, pneumatically, hydraulically, screw or gear; and/or

The control unit includes a control switch, an integrated control circuit and a battery. The control switch, the integrated control circuit and the battery are electrically connected. The control unit regulates the extrusion unit and the atomization unit through the integrated control circuit according to the atomization mode selected by the control switch to control the hydrolysis and dehydrogenation process of the hydrogen storage material and the atomization process of the traditional Chinese medicine liquid.

The control unit preferably further includes at least one of a multifunctional bin temperature sensor, a medicine chamber level sensor, a Chinese medicine liquid bin level sensor, and a liquid capsule level sensor.

The present invention can adopt a variety of miniaturized drive methods, providing intermittent or continuous operation. By manually rotating a control switch, the push rod pushes downward a distance that matches the control switch's rotation amplitude, causing the piston to squeeze the liquid capsule. This squeeze releases water from the capsule, which matches the degree of piston compression, into the chamber for hydrolysis and hydrogen release. Replacing the mechanical drive with an electric motor allows for more precise control of piston movement, and the motor's simpler structure and lower energy consumption allow for long-term use.

Temperature sensors monitor the heat generated by the hydrogen release reaction in the chamber to prevent dangerous overheating or burns caused by excessively high atomizing temperatures. Level sensors and liquid level sensors monitor the solid/liquid content in each chamber, issuing warning signals when the content of a component is low, allowing users to add or replace solid/liquid consumables promptly. This prevents insufficient medication from preventing atomization and potentially delaying treatment or healthcare. Furthermore, observation windows can be installed in the TCM liquid tank to easily monitor the liquid level.

In the second aspect, based on the aforementioned hydrogen Chinese medicine co-inhalation atomization system, the present invention also provides a nebulizer, including an inhalation nozzle and a main body, the main body including a casing and the hydrogen Chinese medicine co-inhalation atomization system accommodated in the casing, the inhalation nozzle is detachably connected to the casing and communicated with the first opening of the Chinese medicine liquid tank.

Preferably, the housing comprises a detachably connected main body top shell, a replacement shell, and a refill shell; the Chinese medicine liquid tank, atomizing unit, extrusion unit, and control unit are detachably fixed in the accommodation space formed by the joint of the main body top shell and the replacement shell; the inhalation nozzle is inserted into the main body top shell and communicates with the first opening of the Chinese medicine liquid tank; the multifunctional tank and liquid capsule are detachably fixed in the refill shell. By joining the refill shell with the replacement shell, the main body top shell, and their respectively fixed components, the atomizer product with the hydrogen Chinese medicine co-inhalation atomization system is formed.

The above-mentioned atomizer design not only provides a simple, compact, and portable atomizer, but also features a detachable and replaceable combination structure. For example, the Chinese medicine liquid tank can be directly added through its first opening, allowing for easy replacement and adjustment of liquid types, making it particularly convenient and practical. The hydrogen-producing portion (multi-functional tank and liquid capsule), where the chemical reaction occurs, can be replaced by removing the refill housing. This is a simple operation, and the replaced refill housing can be recycled to replenish the hydrogen storage material, further reducing costs.

In a third aspect, the present invention provides an atomization method of an atomizer, comprising the following steps:

S1. Assembling: Connecting the suction nozzle to the housing to communicate with the first opening of the Chinese medicine liquid tank;

S2. Start: The control unit adjusts the extrusion unit to squeeze the liquid capsule according to the selected atomization mode to control the hydrolysis and hydrogen release process of the hydrogen storage material;

S3, hydrogen release: the liquid in the liquid capsule is pressed into the medicine chamber to hydrolyze the hydrogen storage material to release hydrogen, and the hydrogen is passed into the traditional Chinese medicine liquid tank;

S4. Atomization: The atomization unit atomizes the Chinese medicine liquid in the Chinese medicine liquid tank, and the hydrogen Chinese medicine co-absorption mist is released from the inhalation nozzle.

Before step S1 , it is also included to determine whether there is sufficient hydrogen storage material in the medicine chamber, sufficient water in the liquid capsule, and sufficient Chinese medicine liquid in the Chinese medicine liquid tank.

After step S4 is in progress or completed, there are the following additional steps:

(1) When the hydrogen storage material or the water in the sac is exhausted, the atomizer no longer produces hydrogen, and the atomizing unit continues to atomize the Chinese medicine liquid and provide Chinese medicine atomizing gas; or

(2) When the hydrogen storage material or the liquid capsule is insufficient, hydrogen production will no longer be allowed, the atomization unit will be stopped, the core shell will be replaced, a chamber with sufficient hydrogen storage material and a liquid capsule with sufficient water will be provided, and the unit will be restarted;

(3) When the amount of liquid in the Chinese medicine liquid tank is insufficient, remove (or do not remove) the suction nozzle, add the required Chinese medicine liquid from the first opening of the Chinese medicine liquid tank (preferably stop hydrogen production or reduce the amount of hydrogen production), and then provide hydrogen and Chinese medicine for co-inhalation again.

The present invention has at least the following beneficial effects:

(1) The present invention is based on the hydrogenation reaction of hydrogen storage materials, and has obtained an integrated atomization system and atomizer with both hydrogen absorption and traditional Chinese medicine atomization functions. The system has a clever structure and is easy to control. Compared with the thermal dehydrogenation process commonly used in the prior art, the hydrogenation process of hydrogen storage materials does not require heating, heat conduction and other components, has low energy consumption, simple equipment structure, and greatly improves the portability and safety of the atomizer. The atomizer and atomization method of the present invention are more environmentally friendly, and the added materials and consumables can be easily reused, resulting in low production and use costs.

(2) The amount of water delivered to the medicine chamber is controlled by the degree of squeezing of the liquid capsule to control the reaction degree and speed of the hydrogen storage material. This solves the technical bottleneck of the existing technology of hydrogen production by hydrolysis, which is difficult to control and difficult to stop once started, and effectively applies the hydrogen production technology by hydrolysis.

(3) The present invention separates the medicine chamber from the upper Chinese medicine liquid tank by setting a buffer chamber structure and a microporous ceramic filter in the multifunctional tank. Not only can the microporous ceramic filter be used to prevent the upper Chinese medicine liquid from coming into contact with the hydrogen storage material and causing an uncontrollable reaction due to the difference in gas and liquid permeability, but it can also use the air pressure and hydraulic pressure balance to buffer and control the rate at which hydrogen enters the Chinese medicine liquid tank.

DETAILED DESCRIPTION

In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

The terms used in the embodiments of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The singular forms "a," "an," "the," and "the" used in the embodiments of the present invention and the appended claims are also intended to include plural forms, and unless the context clearly indicates otherwise, "a plurality" generally includes at least two.

It should also be noted that the terms "include," "comprises," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a product or device comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such product or device. In the absence of further limitations, an element defined by the phrase "comprises a..." does not exclude the presence of other identical elements in the product or device comprising the element.

As shown in Figure 1, a hydrogen Chinese medicine co-inhalation atomization system based on the hydrolysis of hydrogen storage materials to release hydrogen includes a Chinese medicine liquid tank 1, an atomization unit, a multifunctional tank 2, a liquid capsule 3, an extrusion unit 5, and a control unit 6. The specific structure is as follows:

(1) The Chinese medicine liquid tank 1 includes a first opening for communicating with the external environment and a second opening for communicating with the multifunctional tank 2. An atomizing unit, preferably an ultrasonic vibrating plate, is provided on the side wall and/or bottom of the Chinese medicine liquid tank 1 to atomize the Chinese medicine liquid in the Chinese medicine liquid tank 1. A Chinese medicine liquid tank level sensor may also be provided in the Chinese medicine liquid tank 1 to accurately control the liquid level, or an observation window may be provided on the corresponding housing to simply and intuitively monitor the liquid level.

(2) The multifunctional chamber 2 includes a medicine chamber for loading hydrogen storage materials and a buffer chamber above the medicine chamber. The medicine chamber at the bottom is connected to the liquid capsule 3 through a microporous tube. The microporous tube allows the water in the liquid capsule 3 to enter the medicine chamber slowly and controllably, which will not cause the hydrogen storage material in the medicine chamber to react too quickly and violently. In addition, the hydrogen storage material will not enter the microporous tube during storage and use to cause blockage or failure. A microporous ceramic filter is provided between the buffer chamber and the second opening at the bottom of the Chinese medicine liquid tank 1 above it. The microporous ceramic filter preferably adopts a microporous ceramic sheet with a moderate pore size, for example, 1-100 μm, preferably 5-50 μm, and more preferably 10-35 μm. Water molecules are not easy to penetrate under the action of tension, and the Chinese medicine liquid in the Chinese medicine liquid tank 1 will not flow downward into the multifunctional tank 2 and react uncontrollably with the hydrogen storage material. Moreover, after the hydrogen is generated by the reaction in the medicine chamber, it does not enter the Chinese medicine liquid tank immediately. The hydrogen with particularly low density will accumulate to a certain pressure in the buffer chamber above the medicine chamber before it can enter the Chinese medicine liquid tank 1 through the microporous ceramic sheet; and after the hydrolysis hydrogen production reaction is stopped, as the pressure in the buffer chamber decreases, the hydrogen no longer enters the Chinese medicine liquid tank 1 through the microporous ceramic sheet, and the hydrogen retained and stored in the buffer chamber and the medicine chamber forms a sealing effect on the through holes of the microporous ceramic sheet and the microporous tube, thereby ensuring the cleanliness and safety of the medicine chamber. That is, the cooperation between the microporous ceramic filter and the buffer chamber can hinder the exchange of substances other than hydrogen between the traditional Chinese medicine liquid warehouse and the multi-functional warehouse, thereby protecting the material composition, stability and safety of each warehouse.

The hydrogen storage material contains a metal hydride, which is at least one of _MgH2 , _CaH2 , and _ZnH2 , preferably _MgH2 , and its amount accounts for more than 93% of the hydrogen storage material; the hydrogen storage material also contains a promoter and/or a purifier, which is selected from LiOH, KOH, NaOH or citric acid, and its amount accounts for 0.5-2% of the total mass of the hydrogen storage material; the purifier is selected from at least one of iron powder, nickel powder, cobalt powder, and palladium powder, and its amount accounts for 1-5% of the total mass of the hydrogen storage material.

(3) Extrusion unit 5. The main components of the extrusion unit 5 include an extrusion piston, which moves in a controlled manner to squeeze the liquid capsule 3. In addition, it may also include a linkage component to realize the telescopic movement of the extrusion piston. Preferably, the extrusion piston is driven by a motor, air pressure, hydraulic pressure, screw or gear. The extrusion unit 5 squeezes the liquid capsule 3 according to a specified extrusion mode (such as extrusion amount, extrusion rate, extrusion frequency, etc.) through the extrusion piston, and presses the liquid in the liquid capsule 3 from the microporous tube into the medicine chamber of the multifunctional chamber 2 to hydrolyze the hydrogen storage material and release hydrogen. When the hydrogen production process is completed, the extrusion piston retreats and no longer squeezes the liquid capsule 3. The liquid capsule 3 partially recovers its deformation, which reduces the air pressure in the liquid capsule 3. The remaining hydrogen in the multifunctional chamber 2 increases the pressure in the chamber, thereby forming an airtight seal at the outlet of the microporous tube. The liquid in the liquid capsule 31 and the residual liquid in the microporous tube will no longer flow into the medicine chamber of the multifunctional chamber 2, thereby effectively blocking the hydrolysis reaction of the hydrogen storage material.

(4) A control unit 6, comprising a control switch 7, an integrated control circuit, and a battery. The control switch 7 and the integrated control circuit are electrically connected to the battery. The control unit 6 regulates the extrusion unit 5 and the atomization unit through the integrated control circuit according to the atomization mode selected by the control switch 7 to control the hydrolysis and dehydrogenation process of the hydrogen storage material and the atomization process of the traditional Chinese medicine liquid.

Among them, there are multiple optional starting sequences for the hydrolysis and hydrogenation process and the Chinese medicine liquid atomization process. Both processes start up quickly and can be started one after the other or simultaneously. In addition, starting only the Chinese medicine liquid atomization process is also optional, which broadens the application scope of the product of the present invention.

In addition to the above-mentioned composition and structure, the control unit 6 of the present system may also include a number of sensors, for example, at least one of a multifunctional bin temperature sensor, a multifunctional bin material level sensor, a Chinese medicine liquid bin liquid level sensor, and a liquid capsule liquid level sensor. The temperature sensor is used to monitor the heat generated by the hydrogen release reaction in the medicine chamber, and the liquid level sensor is used to monitor the material content in each chamber. The sensor is electrically connected or communicatively connected to the controller to transmit the detection results to the controller in a timely manner, and provides a basis for the subsequent regulation and judgment of the controller. In addition, the system of the present invention can also be connected to the signal of intelligent devices such as mobile terminals, so that users and their guardians can keep abreast of the system usage in a timely manner, and can remotely control the working mode of the hydrogen Chinese medicine co-inhalation atomization system when necessary.

The aforementioned TCM liquid reservoir 1, atomization unit, multifunctional reservoir 2, liquid capsule 3, extrusion unit 5, and control unit 6, along with their specific structures and connections, essentially constitute the present invention's hydrogen-based TCM co-inhalation atomization system. This system has multiple applications, ranging from large-scale equipment that precisely controls the hydrogen production and atomization processes to provide high-dose hydrogen-based TCM co-inhalation atomization to portable atomizers with smaller components.

The nebulizer, particularly a portable nebulizer, as shown in FIG2 , includes an inhalation nozzle 8 and a main unit. The main unit includes a housing 9 and the hydrogen-TCM co-inhalation atomization system housed therein. The inhalation nozzle 8 is detachably connected to the housing 9 to communicate with the first opening of the TCM liquid reservoir 1. When the nebulizer is in operation, the hydrogen-TCM co-inhalation mist is released from the inhalation nozzle for inhalation by the user. This structure is similar to the principle of existing nebulizers.

Another major feature of the atomizer of the present invention is that the housing 9 comprises a detachably connected main body top housing 91, a replacement housing 92, and a refill housing 93. While this detachable assembly structure is somewhat complex, its benefits are significant. Overall, it facilitates the addition and replacement of consumables, reduces operating costs, and ensures safety during use and replacement. Specifically:

(1) Durable parts: The Chinese medicine liquid tank 1, atomizing unit, squeezing unit 5 and control unit 6 are detachably fixed in the accommodation space formed by the main body top shell and the replacement shell. The suction nozzle 8 is inserted into the main body top shell 91 and communicates with the first opening of the Chinese medicine liquid tank 1. Relatively speaking, the Chinese medicine liquid tank 1 is easy to add liquid. Liquid can be added/replaced directly through its first opening. The requirements for the structure of the atomizer are relatively low, and the probability of loss is relatively small. Therefore, the above parts are durable parts of the atomizer and do not need to be replaced frequently.

(2) Replacement part: The multifunctional chamber 2 and the liquid capsule 3 are detachably fixed in the refill shell 93. The medicine chamber of the multifunctional chamber 2 and the liquid capsule 3 connected by the microporous tube are the core components of the atomizer of the present invention and are the key to hydrogen production by hydrolysis. The user does not have the ability to load the medicine by himself, which poses a safety risk. Therefore, the present invention provides a simpler and safer replacement and installation solution for the multifunctional chamber 2 and the liquid capsule 3 and the microporous tube connected thereto. They are assembled and integrated into the refill shell 93. According to the reaction ratio, sufficient liquid capsule capacity is designed to ensure that the hydrogen storage material can be used up. After that, the refill shell 93 is uniformly replaced to replace the above parts. In addition, the microporous ceramic filter between the buffer chamber of the multifunctional chamber 2 and the second opening of the Chinese medicine liquid chamber 1 is preferably fixed at the outlet of the buffer chamber. During transportation and storage, a closable opening of the multifunctional chamber 2 is formed to ensure the cleanliness and safety of the internal medicine.

In the nebulizer, a Chinese herbal liquid is transformed into aerosolized gas through ultrasonic vibrations and then inhaled into the human body. One or more different Chinese herbal liquids can be added to achieve different effects, assisting in the treatment of common human ailments such as cardiovascular diseases, endocrine and metabolic diseases, neurological diseases, digestive diseases, respiratory diseases, ENT diseases, skin diseases, and even tumors. It also has benefits such as relieving fatigue, promoting health and wellness, and beautifying the skin.

The parameters of the atomizer are designed as follows (based on the amount of one refill shell):

Total hydrogen release: Each portion contains approximately 2-3g of magnesium hydride, and the theoretical hydrogen release upon hydrolysis is 3-4L (under normal pressure).

Hydrogen concentration: Hydrogen, Chinese medicine mist and air are inhaled simultaneously, and the volume ratio of hydrogen is about 1-3%.

Equipment weight: It adopts an aluminum alloy casing (including a main body top casing 91, a replacement casing 92 and a replacement core casing 93), and the equipment weighs 200-300g.

Referring to FIG3 , the atomization method of the atomizer with a hydrogen Chinese medicine co-inhalation atomization system specifically includes the following steps:

S1. Assembly: Assemble the main body top shell 91, replacement shell 92, and refill shell 93 (a new refill shell 93 is used when consumables need to be replaced), etc., so that the hydrogen Chinese medicine co-inhalation atomization system is accommodated inside the housing 9, and check whether the amount of Chinese medicine liquid in the Chinese medicine liquid tank 1, the amount of hydrogen storage material in the medicine chamber, and the amount of liquid in the liquid capsule 3 are sufficient; then connect the suction nozzle 8 to the main body top shell 91 of the housing 9, and connect it to the first opening of the Chinese medicine liquid tank 1 through the corresponding opening of the main body top shell 91 to provide a mist outlet for hydrogen Chinese medicine co-inhalation;

S2. Start: The control unit controls the squeezing unit to squeeze the liquid capsule according to the selected atomization mode to control the hydrolysis and hydrogen release process of the hydrogen storage material. For example, by pressing the control switch 7, the squeezing piston extends out of the sliding sealing cavity formed by the refill shell 93 to squeeze the liquid capsule 3. The liquid capsule 3 squeezes out a corresponding amount of water according to the squeezing degree of the squeezing piston;

S3, hydrogen release: The liquid in the sac is pressed into the medicine chamber through the microporous tube to hydrolyze the hydrogen storage material to release hydrogen. Hydrogen is continuously generated and accumulated in the buffer chamber above the medicine chamber. When the pressure in the buffer chamber reaches the threshold, the hydrogen is filtered through the microporous ceramic sheet and then enters the traditional Chinese medicine liquid tank 1;

S4. Atomization: The control unit regulates the atomization process of the ultrasonic plate vibration according to the selected atomization mode, atomizes the Chinese medicine liquid in the Chinese medicine liquid tank 1, and the hydrogen Chinese medicine co-absorption mist is released from the suction nozzle 8; the user uses the suction nozzle 6 to simply inhale the hydrogen Chinese medicine co-absorption mist, and completes hydrogen absorption and Chinese medicine atomization at the same time.

After step S4 is in progress or completed, there are the following additional steps:

(1) When the hydrogen storage material or the water in the sac is exhausted, the atomizer no longer produces hydrogen, and the atomizing unit continues to atomize the Chinese medicine liquid and provide Chinese medicine atomizing gas; or

(2) When the hydrogen storage material or the liquid capsule is insufficient, hydrogen production is stopped, the atomization unit is stopped, the refill shell 93 is replaced, a chamber with sufficient hydrogen storage material and a liquid capsule 3 with sufficient water is provided, and the atomization unit is restarted; or

(3) When the amount of liquid in the Chinese medicine liquid tank is insufficient, remove (or do not remove) the suction nozzle, add the required Chinese medicine liquid from the first opening of the Chinese medicine liquid tank (preferably stop hydrogen production or reduce the amount of hydrogen production), and then provide hydrogen and Chinese medicine for co-inhalation again.
