Description

Technical Field

[0001] This application belongs to the field of electrolysis technology, specifically relating to a gas generation module, a breathing device, and a gas production device. Background Technology

[0002] With the development of science and technology, the ability of hydrogen molecules to neutralize harmful reactive oxygen species has gradually been accepted by society, and hydrogen-oxygen generators have become increasingly popular as hydrogen absorption devices.

[0003] When hydrogen is produced by water electrolysis, hydrogen inevitably carries some water during its escape. Therefore, existing hydrogen-oxygen generators need to separate hydrogen from water first to avoid choking users. To achieve gas-liquid separation, existing technologies usually use gravity sedimentation or centrifugal separation to separate droplets from gas through gravity or centrifugal force. However, this method has two problems: (1) The gas-liquid separation module requires a large space, resulting in a large overall size of the hydrogen-oxygen generator, which cannot meet the requirements of miniaturization; (2) At high flow rates, droplets and gas are often not completely separated and are output together, resulting in poor gas-liquid separation efficiency.

[0004] In summary, the application of hydrogen-oxygen generators is currently mainly limited by their large size and poor gas-liquid separation efficiency, and there are no reports yet on solutions to these problems. Utility Model Content

[0005] Based on the problems existing in the current hydrogen-oxygen generator, this application first provides a gas generation module. The gas generation module, through the cathode chamber and / or anode chamber, is connected to the outside environment only via a gas outlet, thereby reducing the amount of water carried by the escaping gas. This not only eliminates the need for a gas-liquid separation module but also ensures gas-liquid separation efficiency even at relatively high flow rates, overcoming the shortcomings of the current hydrogen-oxygen generator.

[0006] Based on this, the present invention also provides a breathing device and a gas generating device using the above-mentioned gas generating module.

[0007] This application provides the following technical solution:

[0008] A gas generation module includes at least one electrolysis component, the electrolysis component including a cathode chamber with a cathode, an anode chamber with an anode, and a first chamber disposed between the two, the first chamber being provided with a water inlet and separated from at least one adjacent chamber by a water baffle.

[0009] Gas outlets are provided in both the cathode chamber and the anode chamber;

[0010] The chamber separated from the first chamber by a water-blocking component is connected to the outside only through the gas outlet.

[0011] For the cathode chamber and / or anode chamber, this application separates them from the first chamber by a water-blocking component, creating a relatively enclosed space except for the gas outlet. Therefore, even when the gas generated at the cathode or anode escapes through the gas outlet, if it carries a large amount of moisture, the pressure inside the chamber will decrease accordingly. Consequently, under the action of external pressure, some of the moisture is forced back into the chamber, thus reducing the amount of water carried by the escaping gas. Based on the aforementioned design, the gas generation module described in this application can achieve gas-liquid separation without the need for a gas-liquid separation module, breaking through the relevant understanding in the prior art and achieving unexpected technical effects. Moreover, since the gas generation module described in this application does not require a gas-liquid separation module, the gas-liquid separation efficiency is not limited by the gas flow rate. Even at relatively fast gas flow rates, the gas-liquid separation efficiency can still be guaranteed, resulting in a significant improvement in technical performance compared to the prior art.

[0012] Furthermore, the water-blocking component between the cathode chamber and the first chamber is an ion channel for cations, the gas outlet of the cathode chamber is a hydrogen outlet, and the cathode chamber is connected to the outside only through the hydrogen outlet.

[0013] Furthermore, a first conductive element is disposed within the cathode chamber. One end of the first conductive element abuts against the cathode, and the other end abuts against the ion channel of the cation. Through the conduction of the first conductive element, when the cathode is energized, the electrolyzed raw water in the first chamber participates in electrolysis. Subsequently, under the action of voltage, the cations enter the cathode chamber through the ion channel of the cation to continue participating in electrolysis. There is no need to add additional electrolyzed raw water to the cathode chamber, thus reducing the amount of water carried away when hydrogen escapes from the source. On the other hand, since there is no need to add additional electrolyzed raw water, the scouring of the cathode by the electrolyzed raw water is reduced, and the service life of the cathode is increased accordingly.

[0014] Furthermore, the water-blocking component between the anode chamber and the first chamber is an ion channel for anions, the gas outlet of the anode chamber is an oxygen outlet, and the anode chamber is connected to the outside only through the oxygen outlet.

[0015] Furthermore, a second conductive element is provided in the anode chamber. One end of the second conductive element abuts against the anode, and the other end abuts against the ion channel of the anion. Through the conduction of the second conductive element, when the anode is energized, the electrolyzed raw water in the first chamber participates in electrolysis. Subsequently, under the action of voltage, the anions enter the anode chamber through the anion channel to continue participating in electrolysis. Similarly, there is no need to add additional electrolyzed raw water to the anode chamber, thus reducing the amount of water carried away when oxygen escapes from the source. On the other hand, since there is no need to add additional electrolyzed raw water to the anode chamber, the scouring effect of the electrolyzed raw water on the anode is reduced, and the service life of the anode is increased accordingly.

[0016] Furthermore, a pressure relief valve is provided at the gas outlet of the chamber separated from the first chamber by the water-blocking component. In this invention, the cathode chamber and / or anode chamber are relatively enclosed spaces, which may result in high pressure within the chambers. This application achieves control over the output gas pressure by providing a pressure relief valve, thus meeting different user needs and making it suitable for various scenarios.

[0017] Furthermore, a support member is provided in the first chamber, which is arranged parallel to the water-blocking member. The area of ​​the support member is smaller than that of the water-blocking member, thus not affecting the flow of electrolyzed raw water. By providing the support member, the robustness and service life of the electrolysis assembly are increased.

[0018] Furthermore, the support member is provided with several water passage holes; or the support member is a symmetrical bracket.

[0019] Furthermore, the first chamber is provided with an outlet, which is connected to the inlet of the first chamber. A power device is installed on the passage connecting the outlet and the inlet. Driven by the power device, such as a water pump, the electrolyzed raw water flows out of the first chamber through the outlet and is then pumped back into the first chamber through the inlet, thereby forming flowing electrolyzed raw water, promoting ion migration, and thus improving electrolysis efficiency.

[0020] Furthermore, the cathode chamber, the first chamber, and the anode chamber are stacked and arranged, and several through holes are provided through the edges of the chambers;

[0021] The through hole connected to the cathode chamber or anode chamber is a gas outlet, and the through hole connected to the first chamber is a water inlet.

[0022] Furthermore, a gas flow channel is provided between the through hole and the cathode chamber or anode chamber. The gas flow channel has a V-shaped variable diameter structure, with the opening gradually increasing in the direction toward the chamber.

[0023] And / or, a water inlet channel is provided between the through hole and the first chamber, the water inlet channel having a V-shaped variable diameter structure with the opening gradually increasing in the direction toward the chamber.

[0024] By increasing the opening facing the chamber, the gas gathering area of ​​the gas flow channel can be increased, thereby increasing the gas output efficiency; or the water inlet efficiency of the water inlet channel can be increased, so as to fully drive the flow of electrolytic raw water, thereby ensuring the electrolysis efficiency.

[0025] Furthermore, adjacent electrolysis components share a common electrode, which is either an anode or a cathode, and both sides of the common electrode participate in electrolysis. When the gas generation module described in this application includes two or more electrolysis components, the number of electrodes is reduced by setting a common electrode.

[0026] This invention also provides a breathing device that employs the aforementioned gas generation module. The breathing device can provide hydrogen, oxygen, or a mixture of both according to user needs, and also achieves miniaturization of the device itself.

[0027] This utility model also provides a gas generating device, which uses the above-mentioned gas generating module to produce hydrogen and / or oxygen.

[0028] After adopting the above technical solution, the present invention has the following beneficial effects:

[0029] 1. The gas generation module described in this utility model reduces the amount of water carried by the escaping gas by designing the cathode chamber and / or anode chamber as a sealed space that is only connected to the outside through the gas outlet. Compared with the prior art, it not only eliminates the need for a gas-liquid separation module, reducing the size of the equipment, but also ensures the efficiency of gas-liquid separation even at a relatively fast gas flow rate.

[0030] 2. The gas generation module of this utility model is provided with an outlet connected to the water inlet of the first chamber, and realizes the flow of electrolyzed raw water under the drive of the power device, thereby promoting ion migration and improving electrolysis efficiency.

[0031] 3. The gas generation module of this utility model reduces the number of electrodes when there are two or more electrolysis components by setting up a shared electrode, thereby reducing production costs. Attached Figure Description

[0039] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0040] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0041] Because hydrogen molecules can neutralize harmful reactive oxygen species, hydrogen absorption devices are becoming increasingly popular. However, hydrogen inevitably carries some water during its escape, so it is necessary to separate the hydrogen from the water before absorption to prevent users from choking on the water. Due to the size limitations of the gas-liquid separation module, miniaturization and portability of hydrogen absorption devices are not feasible. On the other hand, at higher flow rates, in existing technologies, droplets and gas are often not completely separated before being output together, resulting in poor gas-liquid separation efficiency.

[0042] In view of this, such as Figure 1-3 As shown, this utility model provides a gas generation module, including at least one electrolysis component; when multiple electrolysis components are provided, the generation efficiency of hydrogen and oxygen is improved accordingly.

[0043] The electrolysis assembly includes a cathode chamber 3 with a cathode 1, an anode chamber 4 with an anode 2, and a first chamber 5 located between the two. Both the cathode chamber 3 and the anode chamber 4 are provided with gas outlets for outputting hydrogen and oxygen generated during the electrolysis process, respectively.

[0044] The first chamber 5 is provided with a water inlet 7 and is separated from at least one adjacent chamber by a water baffle 6 to limit the timely replenishment of water in this chamber by the electrolyzed raw water in the first chamber 5.

[0045] In this invention, the electrode can be made of conductive diamond or other conductive materials, such as one or a combination of ceramic, titanium, platinum, gold, titanium alloy, nickel, palladium, platinum-ruthenium alloy or stainless steel.

[0046] Furthermore, in this utility model, at least one electrode of the electrolysis component is made of conductive diamond material. For example, cathode 1 is made of conductive diamond material, or anode 2 is made of conductive diamond material, or both cathode 1 and anode 2 are made of conductive diamond material.

[0047] In the prior art, electrodes used for electrolysis often use precious metal electrodes such as platinum, ruthenium, and iridium. Considering the limited resources of precious metals, the development prospects of such electrodes are limited. In this invention, conductive diamond electrodes are used, which reduces the dependence on precious metal resources. Considering that carbon resources for preparing conductive diamond are more abundant, this invention has better development prospects.

[0048] To reduce the amount of water carried away when the gas escapes, in this invention, the chamber separated from the first chamber 5 by the water-blocking component 6 is only connected to the outside through the gas outlet, thus forming a relatively closed space. It should be noted that... Figure 1 This is an exploded schematic diagram of the electrolysis assembly of this application. In this application, the cathode chamber 3, the first chamber 5 and the anode chamber 4 need to be arranged adjacent to each other to avoid water leakage and gas leakage.

[0049] During electrolysis, raw water enters the first chamber 5 through inlet 7 and is electrolyzed into hydrogen ions and hydroxide ions. Then, under voltage, the ions migrate, generating hydrogen and oxygen at cathode 1 and anode 2, respectively. As the gas is generated, the pressure inside the chamber increases, and the gas escapes through the gas outlet. During this process, due to the water-blocking component 6, the current chamber is relatively closed, with only the gas generated at the electrodes causing a change in pressure. If the gas carries a significant amount of water during escape, the pressure inside the chamber decreases considerably. Under external pressure, this water is forced back into the chamber. Therefore, the structure of this invention can reduce the amount of water carried by the escaping gas. Based on the aforementioned design, the gas generation module of this application can achieve gas-liquid separation without the need for a gas-liquid separation module, breaking through existing technological limitations and achieving unexpected technical effects. Moreover, since the gas generation module of this application does not require a gas-liquid separation module, the gas-liquid separation efficiency is not limited by the gas flow rate. Even at a relatively fast gas flow rate, the gas-liquid separation efficiency can still be guaranteed. Compared with the prior art, the technical effect is significantly improved.

[0050] Example 1

[0051] In this embodiment, considering that the raw water is electrolyzed into hydrogen ions and hydroxide ions in the first chamber 5, the water-blocking component 6 between the cathode chamber 3 and the first chamber 5 needs to be set as an ion channel for cations so that cations such as hydrogen ions can pass through and continue to participate in electrolysis at the cathode 1. Accordingly, the gas outlet of the cathode chamber 3 is the hydrogen outlet 9, and the cathode chamber 3 is only connected to the outside through the hydrogen outlet 9.

[0052] It should be noted that although the water-blocking component 6 in this embodiment has a water-blocking function, since cations require water as a medium during migration, the water-blocking component 6 in this embodiment does not completely block water. It still allows ions to pass through with water during migration. This portion of water can also prevent the cathode 1 inside the cathode chamber 3 from burning dry when no additional water is introduced. On the other hand, compared with the prior art where the cathode 1 is subject to scouring by the electrolytic raw water when water is introduced, this embodiment can avoid the cathode 1 being scouring because no additional water is introduced at the cathode chamber 3. Therefore, it delays the shedding of its catalyst layer and increases its service life.

[0053] The ion channel of the cation with water-blocking function also allows gas to pass through. Since the cathode chamber 3 is a relatively closed chamber, even if hydrogen escapes into the first chamber 5 through the water-blocking component 6, the amount of water carried by the hydrogen escaping through the hydrogen outlet 9 can still be kept small. For example, the water-blocking component 6 can be set as a low-crosslinking sulfonated polymer membrane, a partially crosslinked polyvinyl alcohol membrane, or other structural forms.

[0054] The working principle of the low crosslinking degree sulfonated polymer membrane is to increase the membrane porosity by reducing the crosslinking degree, allowing gas to pass through, while the sulfonic acid groups maintain cation transport.

[0055] The working principle of partially cross-linked polyvinyl alcohol membranes is to control the hydrophilic / hydrophobic balance within the membrane through cross-linking, allowing cations and gases to pass through together.

[0056] Furthermore, if the water-blocking component 6 allows gas to pass through, the hydrogen generated during electrolysis may escape into the first chamber 5, reducing the gas output efficiency of the hydrogen outlet 9. Therefore, the ion channel for cations preferably has a gas-blocking function, so that all hydrogen generated in the cathode chamber 3 escapes through the hydrogen outlet 9. For example, the water-blocking component 6 can be a cation exchange membrane, a polytetrafluoroethylene (PTFE) composite membrane, a multilayer hydrophobic coating membrane, or other structural forms.

[0057] The working principle of the polytetrafluoroethylene composite membrane is to disperse the perfluorosulfonic acid membrane in the porous polytetrafluoroethylene framework, and to use the hydrophobicity and density of polytetrafluoroethylene to block the gas.

[0058] The working principle of the multilayer hydrophobic coating membrane is to coat the surface of the cation exchange layer with an ultrathin polyvinylidene fluoride layer to block liquid water and gas from passing through.

[0059] To ensure that the raw water in the first chamber 5 participates in electrolysis, a first conductive element (not shown in the figure) is provided in the cathode chamber 3. One end of the first conductive element abuts against the cathode 1, and the other end abuts against the ion channel of the cation. When the cathode 1 is energized, the ion channel of the cation, such as the cation exchange membrane, becomes charged by means of the conduction of the first conductive element, thereby electrolyzing the raw water in the first chamber 5.

[0060] The first conductive element can be a solid structure such as nickel foam, or it can achieve conductivity by pre-storing water in the cathode chamber 3. In this case, the water flow is the first conductive element. For the first conductive element in the form of water flow, it can achieve contact with the cathode 1 by means of the swelling property of the ion channels of cation exchange membranes, etc. That is, in the initial state, the water flow in the cathode chamber 3 does not contact the structures on both sides. As the electrolyzed raw water enters the first chamber 5, the water-blocking element 6 swells accordingly. Due to the high water pressure in the first chamber 5, the water-blocking element 6 expands towards the cathode chamber 3, and the water flow then contacts the structures on both sides, thus achieving conductivity.

[0061] On the other hand, in this embodiment, the cathode 1 and the water baffle 6 are spaced apart, that is, the cathode 1 is configured as a side wall of the cathode chamber 3. When the gas generating module is provided with two or more electrolysis components, since the cathode 1 is directly exposed to the outside, the two adjacent electrolysis components can share the cathode 1. At this time, both sides of the cathode 1 participate in electrolysis, which improves the utilization rate of the cathode 1.

[0062] If the cathode 1 is placed close to the water-blocking component 6, the first conductive component can be omitted. When the cathode 1 is energized, it can directly electrolyze the raw water in the first chamber 5 through the wetted cation exchange membrane and other water-blocking components 6. However, at this time, an additional sidewall needs to be set on the other side of the cathode chamber 3 to seal the cathode chamber 3. Since the cathode 3 is not exposed to the outside, when multiple electrolysis components are arranged adjacent to each other in the gas generation module, the cathode 1 cannot be shared. Therefore, compared with the previous embodiment, although the first conductive component is saved, the number of electrodes increases.

[0063] Example 2

[0064] In this embodiment, considering that hydrogen ions and hydroxide ions are generated during the electrolysis of raw water in the first chamber 5, in order to ensure that hydroxide ions can continue to participate in electrolysis at the anode 2, the water-blocking component 6 between the anode chamber 4 and the first chamber 5 needs to be set as an ion channel for anions. At this time, the gas outlet of the anode chamber 4 is the oxygen outlet 10, and the anode chamber 4 is only connected to the outside through the oxygen outlet 10.

[0065] It should be noted that although the water-blocking component 6 in this embodiment has a water-blocking function, since anions require water as a medium during migration, the water-blocking component 6 in this embodiment does not completely block water. It still allows ions to carry water through during migration. This portion of water can also prevent the anode 2 inside the anode chamber 4 from dry burning when no separate water inlet is provided. On the other hand, compared with the prior art where the anode 2 is subject to scouring by the electrolyzed raw water during water inlet, this embodiment can avoid the anode 2 being scouring because no additional water inlet is provided at the anode chamber 4. Therefore, it delays the shedding of its catalyst layer and thus increases its service life.

[0066] The anion channel with water-blocking function also allows gas to pass through. Since the anode chamber 4 is a relatively closed chamber, even if oxygen escapes into the first chamber 5 through the water-blocking element 6, the amount of water carried by the oxygen when escaping through the oxygen outlet 10 is still relatively small. For example, the water-blocking element 6 can be set as a porous ceramic anion exchange membrane, an ion-selective gel membrane, or other structural forms.

[0067] Among them, the working principle of porous ceramic anion exchange membrane is to set micron-level pores to allow gas diffusion, while selectively transporting anions through surface charge.

[0068] The working principle of ion-selective gel membranes is to set anion exchange groups in a polymer gel network, which allows anion migration, while the porosity of the gel also allows gas to pass through.

[0069] If the water-blocking component 6 allows gas to pass through, the oxygen generated during electrolysis may escape into the first chamber 5, reducing the gas output efficiency of the oxygen outlet 10. Therefore, the anion channel preferably has a gas-blocking function, so that all oxygen generated in the anode chamber 4 escapes through the oxygen outlet 10. For example, the water-blocking component 6 can be an anion exchange membrane, a biomimetic anion transport channel, an all-silicon molecular sieve, or other structural forms.

[0070] The working mechanism of the biomimetic anion transport channel is to stabilize the channel structure by protecting the outer shell with hydrophobic alkyl chains, thereby controlling the porosity. It allows anions to pass through, but blocks gas molecules.

[0071] The working principle of all-silicon molecular sieves is based on a pure silicon framework of non-polar groups with strong hydrophobicity. The pore size is adjusted to... It selectively allows anions to pass through while blocking gases.

[0072] To ensure that the raw water in the first chamber 5 participates in electrolysis, a second conductive element (not shown in the figure) is provided in the anode chamber 4. One end of the second conductive element abuts against the anode 2, and the other end abuts against the anion channel. When the anode 2 is energized, the ion channels of anions, such as the wet anion exchange membrane, are also charged by the conduction of the second conductive element, thereby electrolyzing the raw water in the first chamber 5.

[0073] The second conductive element can be a solid structure such as nickel foam, or it can achieve conductivity by pre-filling water in the anode chamber 4. In this case, the water flow is the second conductive element. For the water flow type of the second conductive element, it can achieve contact with the anode 2 by means of the swelling property of the ion channels of anions such as anion exchange membranes. That is, in the initial state, the water flow in the anode chamber 4 does not contact the structures on both sides. As the electrolyzed raw water enters the first chamber 5, the water-blocking element 6 swells accordingly. Due to the high water pressure in the first chamber 5, the water-blocking element 6 expands towards the anode chamber 4, and the water flow then contacts the structures on both sides, thus achieving conductivity.

[0074] On the other hand, in this embodiment, the anode 2 and the water baffle 6 are spaced apart, that is, the anode 2 is configured as a side wall of the anode chamber 4. When the gas generation module is provided with two or more electrolysis components, since the anode 2 is directly exposed to the outside, the two adjacent electrolysis components can share the anode 2. At this time, both sides of the anode 2 participate in electrolysis, which improves the utilization rate of the anode 2.

[0075] If the anode 2 is placed close to the water-blocking component 6, the second conductive component can be omitted. When the anode 2 is energized, it can directly electrolyze the raw water in the first chamber 5 through the wetted anion exchange membrane and other water-blocking components 6. However, at this time, an additional sidewall needs to be set on the other side of the anode chamber 4 to seal the anode chamber 4. Since the anode 2 is not exposed to the outside, it is not possible to share the anode 2 when multiple electrolysis components are arranged adjacent to each other in the gas generation module. Therefore, compared with the previous embodiment, although the second conductive component is saved, the number of electrodes increases.

[0076] Regarding the location of the water-blocking component 6, if only hydrogen is needed, the water-blocking component 6 can be installed only between the cathode chamber 3 and the first chamber 5 to save on the gas-liquid separation process here and increase the gas output efficiency. In this case, the gas generation module can be installed at the hydrogen production equipment. On the other hand, since no additional water inlet is provided at the cathode chamber 3, even if the cations carry water into the cathode chamber 3, the amount of water here is still small, and the amount of hydrogen dissolved in water is also small. Compared with the prior art, where some hydrogen is dissolved in water and does not escape, this application can further increase the hydrogen escape efficiency.

[0077] If only oxygen is needed, a water-blocking component 6 can be installed only between the anode chamber 4 and the first chamber 5 to save on the gas-liquid separation process here and increase the gas output efficiency. In this case, the gas generation module can be installed at the oxygen generator. On the other hand, since no additional water inlet is provided at the anode chamber 4, even if hydroxide ions carry water into the anode chamber 4, the amount of water here is still small, and the amount of oxygen dissolved in water is also small. Compared with the prior art, where some oxygen is dissolved in water and does not escape, this application can further increase the oxygen escape efficiency.

[0078] Alternatively, water baffles 6 can be installed between the cathode chamber 3 and the first chamber 5, and between the anode chamber 4 and the first chamber 5. This can save the gas-liquid separation process for the generation of hydrogen and oxygen. In this case, the gas generation module can be installed at the breathing device.

[0079] In the prior art, the gas-liquid separation module is equipped with corresponding water inlets and gas inlets. The gas inlets are used to output hydrogen or oxygen, while the water inlets are used to output the liquid accumulated in the device for recycling and reuse, allowing it to continue to participate in electrolysis. However, due to the setting of the water inlets, the gas-liquid separation module is not a closed space, and hydrogen or oxygen cannot accumulate in the gas-liquid separation module and be output in the form of high pressure.

[0080] Example 3

[0081] In this embodiment, considering that high pressure can increase the solubility of hydrogen and oxygen in blood, a pressure relief valve is also provided at the gas outlet of the chamber separated from the first chamber 5 by the water-blocking component 6. During the initial stage of electrolysis, the pressure relief valve is closed, and the corresponding chamber is a closed space. The generated gas continuously accumulates to form high-pressure gas. When the gas pressure reaches the set pressure, the pressure relief valve opens, and the gas can be continuously output at a higher pressure. For example, when the cathode chamber 3 is separated from the first chamber 5 by the water-blocking component 6, hydrogen can be output under high pressure; when the anode chamber 4 is separated from the first chamber 5 by the water-blocking component 6, oxygen can be output under high pressure; or, preferably, both hydrogen and oxygen can be output under high pressure.

[0082] Alternatively, the pressure relief valve can remain open, allowing hydrogen and / or oxygen to be smoothly output from the gas outlet during the initial stage of electrolysis, but the output gas will be at atmospheric pressure at this time.

[0083] Example 4

[0084] After the raw water in the first chamber 5 undergoes electrolysis, the ions need to pass through the water-blocking member 6 to enter the adjacent chamber. However, the water-blocking member 6 is usually made of flexible material and cannot provide support. Therefore, the structural stability of the first chamber 5 is relatively weak at this point. In order to increase the stability of the first chamber 5, one or more support members 11 are provided in the first chamber 5 in this embodiment. The support members 11 are arranged parallel to the water-blocking member 6, and the area of ​​the support members 11 is smaller than that of the water-blocking member 6, so as to avoid affecting the flow of the raw water.

[0085] When multiple support members 11 are provided, in order to avoid the support members 11 blocking ion migration, the multiple support members 11 need to be set at intervals to leave a path for ion migration.

[0086] When only one support member 11 with a large coverage area is set, in order to ensure that the cations or anions generated in the first chamber 5 can smoothly enter the cathode chamber 3 or the anode chamber 4 and to avoid the support member 5 from blocking the migration of ions, several water passage holes 12 need to be set on the support member 11 to connect the two sides of the first chamber 5 separated by the support member 11. Alternatively, the support member 11 can also adopt a symmetrical support structure such as a single X-shape or multiple X-shapes connected together.

[0087] Example 5

[0088] When the electrolyzed raw water in the first chamber 5 is relatively still, the electrolysis reaction can still proceed normally. Therefore, the first chamber 5 can be equipped with only an inlet 7, which can be replenished after the electrolyzed raw water in it is completely consumed.

[0089] Alternatively, to ensure electrolysis efficiency, in this embodiment, an outlet 8 may be provided at the first chamber 5, the outlet 8 being connected to the inlet 7 of the first chamber 5, and a power device is provided on the passage connecting the outlet 8 and the inlet 7.

[0090] Under the action of a power device such as a water pump in the circulation path, the electrolyzed raw water in the first chamber 5 that has not yet participated in electrolysis flows out of the first chamber 5 through the outlet 8, and is then pumped back into the first chamber 5 through the inlet 7. Compared with the static electrolyzed raw water where ion migration depends on a slow diffusion process, the flowing electrolyzed raw water in this embodiment can promote ion migration, reduce the resistance to ion migration, and thus improve the electrolysis efficiency.

[0091] Example 6

[0092] In this embodiment, the cathode chamber 3, the first chamber 5, and the anode chamber 6 are stacked and arranged, and several through holes are provided through the edges of the chambers. Among them, the through holes connected to the cathode chamber 3 or the anode chamber 4 are gas outlets, and the through holes connected to the first chamber 5 are water inlets 7. By stacking multiple chambers, the volume of the gas generation module of this utility model can be further reduced, thereby further promoting its miniaturization.

[0093] Furthermore, a gas flow channel 13 is provided between the through hole and the cathode chamber 3 or the anode chamber 5. The gas flow channel 13 has a V-shaped variable diameter structure, with the opening gradually increasing in the direction towards the chamber to increase the gas accumulation area.

[0094] A water inlet channel 14 is provided between the through hole and the first chamber 5. The water inlet channel 14 has a V-shaped variable diameter structure, with the opening gradually increasing in the direction towards the chamber to increase the water outlet coverage area and fully drive the flow of electrolyzed raw water in the first chamber 5, thereby ensuring electrolysis efficiency.

[0095] Furthermore, if an outlet 8 is provided at the first chamber 5, a water outlet channel 15 is also required between the through hole and the first chamber 5. The water outlet channel 15 is preferably a V-shaped variable diameter structure, with the opening increasing in the direction toward the chamber to increase the water collection area.

[0096] This invention also provides a breathing device using the above-mentioned gas generation module, which provides users with hydrogen, oxygen or a mixture of the two gases. Since the above-mentioned gas generation module is used, the gas-liquid separation module can be omitted, so the breathing device of this invention can be miniaturized and its applicable scenarios can be increased.

[0097] Example 7

[0098] In this embodiment, the breathing device separates the cathode chamber 3 from the first chamber 5 and the anode chamber 4 from the first chamber 5 by using a water-blocking component 6. This reduces the amount of water carried by the hydrogen and oxygen output through the gas outlet, thus preventing users from choking. At the same time, the appropriate amount of water can also keep the hydrogen and oxygen moist, preventing them from becoming too dry and reducing the user experience.

[0099] On the other hand, since the cathode chamber 3 and the anode chamber 4 are relatively closed chambers, the breathing device in this embodiment can also output hydrogen and oxygen in a high-pressure state through the setting of the pressure relief valve, making it easier for users to absorb.

[0100] Alternatively, the pressure relief valve can be installed only at hydrogen outlet 9 to control the output of hydrogen at high pressure, while oxygen is output at normal pressure; or the pressure relief valve can be installed only at oxygen outlet 10 to control the output of oxygen at high pressure, while hydrogen is output at normal pressure.

[0101] This invention also provides a gas generating device using the above-mentioned gas generating module, which can be used to produce hydrogen and / or oxygen. By omitting the gas-liquid separation module, the volume of the gas generating device in this invention is reduced accordingly.

[0102] For example, excess electrical energy generated at relatively low costs, such as photovoltaic power generation and wind power generation, can be converted into hydrogen and / or oxygen through the gasification equipment of this utility model and stored for later use.

[0103] The above are merely preferred embodiments of this application. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
