Technical Field

The present invention relates to a hydrogen generator, and more particularly to a hydrogen generator capable of selectively adjusting the flow direction of gas and water, wherein the hydrogen generator has a hydrogen cup containing a gas injection assembly with a micro bubble gas outlet structure.

Background

Since ancient times, human beings have invested in many studies for prolonging life, and many medical techniques have been developed for treating diseases. However, the development of medical technology today places more emphasis on active preventive medicine than passive treatment in the past, for example: research on health foods, screening of genetic diseases, and preventive and therapeutic agents for risk factor avoidance. In addition, in order to prolong the life of human beings, many anti-aging and anti-oxidation technologies are being developed and widely used by the public, including coated health care products and anti-oxidation foods/medicines.

The research shows that: humans produce unstable oxygen (O +) due to various causes, such as disease, diet, environment or lifestyle, also known as free radicals (harmful free radicals). The free radical is an atom, molecule or ion with a single unpaired electron, and can attack the cell membrane, cell and tissue of the human body to snatch the electrons of other atoms, so that the chain peroxidation reaction is generated in the body. Peroxidation can lead to degenerative syndromes in the body, such as vascular fragility, brain cell aging, immune system deterioration, cataracts, degenerative arthritis, sagging skin and systemic aging. Many studies have pointed out that the molecular group of hydrogen-rich water is small, so that it can easily enter into cell channel to be absorbed, and participate in metabolism of human body to promote cell detoxification. Drinking hydrogen-rich water can indirectly reduce the number of free radicals of human body, and the acidic constitution can be restored to the healthy alkaline constitution, thereby achieving the effects of eliminating chronic diseases, beautifying and health care.

In the prior art, most hydrogen generators capable of simultaneously producing hydrogen-containing water are provided with an electrolysis module to generate hydrogen-containing gas, then the hydrogen-containing gas is introduced into drinking water, and then the hydrogen-containing gas which is not dissolved into the drinking water is output to be provided for a user to inhale. However, when hydrogen-containing gas is introduced into drinking water, it produces a low frequency sound. If a user uses the hydrogen generator to inhale the hydrogen-containing gas during sleeping, the low-frequency sound will easily affect the sleeping quality of the user, and will adversely affect the health of the user. Therefore, how to solve the problem of connection between the hydrogen water cup and the electrolysis module is one of the issues that needs to be researched and developed.

In addition, the hydrogen generator often produces hydrogen-containing water by directly pumping hydrogen-containing gas into water through the vent pipe, but the hydrogen-containing gas is not sufficiently fine bubbles injected into water, so that the hydrogen-containing gas has too small contact area with water to be smoothly dissolved in water. According to the international hydrogen molecular standards association (IHSA) published in 2017, it is stated that hydrogen concentration in hydrogen-containing water is higher than 0.5ppm by mass concentration to produce biological effect. Whereas the maximum physical limit of hydrogen solubility in water under standard conditions, i.e., one atmosphere at 20 degrees celsius, is 1.6 ppm. Therefore, how to make the hydrogen content in water higher than 0.5ppm and toward 1.6ppm is another topic that needs to be developed.

Referring to fig. 1 and fig. 2A to 2D, fig. 1 is a functional block diagram of a hydrogen generator E capable of selectively adjusting a gas flow direction according to an embodiment of the present invention, fig. 2A is an exploded view of the hydrogen generator E according to fig. 1, fig. 2B is a cross-sectional view of an electrolyte filter module 23 according to fig. 2A, fig. 2C is a top view of an integrated flow channel device 3 according to fig. 2A, and fig. 2D is an exploded view of the integrated flow channel device 3 according to fig. 2C. As shown in fig. 1 and 2A, the hydrogen generator E of the present invention comprises an electrolysis module 1, a water tank 2, an integrated flow channel device 3, a humidification cup 4, a condensation filter device 5, a filter rod 60, an atomizer 7, a hydrogen cup 8, and a frame 80 for fixing the hydrogen cup 8. The electrolysis module 1 is disposed in the water tank 2, the water tank 2 includes a water tank body 21 and a water tank upper cover 22, and an electrolyte filter module 23 is disposed above the water tank upper cover 22. Wherein, as shown in FIG. 2B, the electrolyte filtering module 23 comprises one or more steel wool and polyester synthetic fiber wool, the steel wool and the like can be arranged at an inclined angle and are arranged upward at intervals one by one to form a continuous upward slope channel. The humidifying cup 4 and the condensing and filtering device 5 can be stacked on the water tank 2. The electrolysis module 1 is used for electrolyzing water to generate hydrogen-containing gas, which comprises a part of hydrogen and a part of oxygen (e.g. about 66% hydrogen and about 33% oxygen), or in other embodiments, the hydrogen-containing gas may comprise 100% hydrogen. The water tank 2 can be used for containing electrolyzed water and receiving hydrogen-containing gas output by the electrolysis module 1, and then the electrolyzed water can be output by the electrolyte filtering module 23, and the electrolyte filtering module 23 has a continuous upward slope channel and comprises one or a plurality of steel wool and polyester synthetic fiber wool, so that the electrolyte in the hydrogen-containing gas can be filtered by the electrolyte filtering module 23, and the continuous upward slope channel can also block partial liquid components in the hydrogen-containing gas. As shown in fig. 2C and 2D, the integrated flow channel device 3 includes an upper cover 30 and a lower cover 31, and the gas inlet channel 35, the gas outlet channel 36 and the gas communication channel 37 are located between the upper cover 30 and the lower cover 31. The lower cover 31 is an integrally formed structure. The term "integrally molded" includes integrally injection molded or integrally molded by integrating different parts by welding. In practical applications, as shown in fig. 1 and fig. 2A to fig. 2D, the integrated flow channel device 3 is vertically stacked above the humidification cup 4, and the humidification cup 4 is vertically stacked above the water tank 2. Referring to fig. 3, fig. 3 is a top view of the hydrogen generator E according to fig. 2. The lower cover 31 has a condensing and filtering accommodating space 320 for accommodating the condensing and filtering device 5. The humidifying cup 4 is stacked between the integrated flow channel device 3 and the water tank 2, and is embedded with the lower cover 31. The condensing and filtering device 5 can be used for condensing and filtering the hydrogen-containing gas. The condensation filtering device 5 may have a condensation flow passage 50. In practical applications, the condensing and filtering device 5 can be embedded into the integrated flow channel device 3 and can be pulled out for replacement. The filter rods 60 may be used to filter hydrogen containing gases. The atomizer 7 is engaged with the lower cap 31 and coupled to the outlet channel 36 to receive the hydrogen-containing gas. The atomizer 7 further generates an atomizing gas to be mixed with the hydrogen-containing gas to form the health gas. The hydrogen cup 8 can be used for containing drinking water, and the hydrogen cup 8 is used for injecting hydrogen-containing gas into the drinking water to form hydrogen-containing water. In practical applications, the hydrogen cup 8 can be engaged with the frame 80 and then coupled (or directly connected) to the integrated flow channel device 3, and if the hydrogen cup 8 is disengaged from the frame 80 and not coupled to the integrated flow channel device 3, the electrolysis module 1 will stop operating. The inlet flow channel 35 and the outlet flow channel 36 can be selectively coupled to the hydrogen cup 8, and the gas communication flow channel 37 can be selectively coupled to the inlet flow channel 35 and the outlet flow channel 36.

Thus, the hydrogen-containing gas can be transported between the humidification cup 4, the condensation and filtration device 5, the filter rod 60, the atomizer 7 and the hydrogen water cup 8 through the integrated flow channel device 3. In one embodiment, the humidification cup 4, the condensation filter device 5, and the atomizer 7 may be directly coupled to the lower cover 31. Or further, the hydrogen cup 8 may also be directly coupled to the lower cover 31.

In one embodiment, the electrolysis module 1 may be accommodated in the water tank 2 and may receive the electrolyzed water from the water tank 2 to perform electrolysis to generate the hydrogen-containing gas. After the electrolysis module 1 electrolyzes the electrolyzed water, the electrolysis module 1 directly generates hydrogen-containing gas in the water tank 2. In practical applications, the periphery of the water tank 2 may have a honeycomb structure 24, so as to increase the rigidity of the water tank 2 and prevent the hydrogen-containing gas from expanding the water tank 2 and deforming. Furthermore, the honeycomb structure also helps the hydrogen-containing gas to move toward the communication chamber 41 due to the rigidity of the water tank 2, rather than staying in the water tank 2 and thus expanding the water tank 2.

The humidifying cup 4 comprises a humidifying chamber 40, a communication chamber 41 and a filter chamber 42. The humidification chamber 40 contains make-up water for humidifying the hydrogen-containing gas. The communication chamber 41 can be used to communicate the water tank 2 with the integrated flow channel device 3, so as to allow the hydrogen-containing gas to enter the condensation flow channel 50. In this embodiment, the electrolyte filtering module 23 can be placed in the communicating chamber 41, so that the hydrogen-containing gas is filtered once before entering the condensing channel 50 through the communicating chamber 41. The filter chamber 42 may be configured to receive a filter rod 60 such that the filter rod 60 filters the hydrogen-containing gas flowing through the filter chamber 42. Wherein, the humidifying chamber 40, the communicating chamber 41 and the filtering chamber 42 are not communicated with each other. In addition, the lower cover 31 of the integrated flow channel device 3 further has a condensation communication channel 330, a humidification communication channel 331 and a filtration communication channel 332. The condensation communication channel 330 is used for communicating the water tank 2 and the condensation filtering device 5 through the communication chamber 41, the humidification communication channel 331 is used for communicating the condensation flow channel 50 and the humidification chamber 40, the filtering communication channel 332 is used for communicating the humidification chamber 40 and the filtering chamber 42, and the filtering chamber 42 is coupled to the inlet flow channel 35 to output the filtered hydrogen-containing gas.

In detail, the hydrogen generator E of the present invention is stacked and embedded with other elements by the integrated flow channel device 3, so that the hydrogen generator E of the present invention has the gas path as shown in fig. 1 for flowing the hydrogen-containing gas therein. To illustrate the flow of the hydrogen-containing gas more clearly, please refer to fig. 4, in which fig. 4 is a schematic diagram illustrating the flow of the hydrogen-containing gas in the hydrogen generator E of fig. 1. As shown in fig. 4, the electrolysis module 1 electrolyzes the electrolyzed water to generate the hydrogen-containing gas, and since the electrolysis module 1 can be disposed in the water tank 2, the hydrogen-containing gas is outputted and contained in the water tank 2. Then, the hydrogen-containing gas sequentially flows through the communication chamber 41 of the humidification cup 4, the condensation communication channel 330 of the integrated flow channel device 3, the condensation flow channel 50 of the condensation filtering device 5, the humidification communication channel 331 of the integrated flow channel device 3, the humidification chamber 40 of the humidification cup 4, the filtration communication channel 332 of the integrated flow channel device 3, the filtering chamber 42 of the humidification cup 4, the filtering rod 60, the air inlet flow channel 35, the air outlet flow channel 36, the flame arrester 94 and the atomizer 7 of the integrated flow channel device 3. The hydrogen-containing gas between the inlet flow channel 35 and the outlet flow channel 36 can selectively flow through the hydrogen cup 8 or the gas communication flow channel 37 of the integrated flow channel device 3. However, it should be understood that the flow direction of the hydrogen-containing gas is one embodiment of the hydrogen generator E of the present invention, and those skilled in the art can adjust the sequence of the components according to the requirement, and the invention is not limited thereto.

In one embodiment, a filter 61 may be further included for filtering microorganisms or killing bacteria in the hydrogen-containing gas. The components in the filter 61 may include at least one of activated carbon, nano-silver sputtering, polyethylene terephthalate (PET), and polypropylene (PP) fiber cloth. The antibacterial types can include staphylococcus aureus, escherichia coli, pseudomonas aeruginosa, drug-resistant staphylococcus aureus and the like. It should be understood that one skilled in the art can add a plurality of filters 61 and adjust the position of the filters according to the needs, and the invention is not limited thereto. The filter 61 may be placed before the flame arrester 94 (fig. 4), or may be placed in the atomizer 7 or at the outlet of the atomizer 7 as a disposable part.

Flame arrestor 94 may, in one embodiment, comprise at least one of a metal mesh filter element and a corrugated filter element. The metal mesh filter element can be made of stainless steel or copper mesh with the diameter of 0.23-0.315mm and formed by overlapping a plurality of layers. The corrugated filter element can be supported by stainless steel, copper-nickel alloy, aluminum or aluminum alloy, can be used to stop the violent flame of deflagration, and can bear the corresponding mechanical and thermal actions. Flame arrestor 94 may be used to block the flow of a fire source through flame arrestor 94 and thereby isolate the two spaces to prevent the spread of a fire from one side of flame arrestor 94 to the other, which may result in the spread of a fire through the gas flow path and the resulting explosion. In this embodiment, flame arrestor 94 is disposed between atomizer 7 and outlet flow channel 36. In addition to the flame arrester 94 for preventing the fire from spreading, the hydrogen generator E of the present invention can utilize the make-up water in the humidification chamber 40 and the electrolyzed water in the water tank 2 to achieve multi-zone fire arresting. In detail, the hydrogen generator E can be divided into three regions, i.e., the water tank 2 to the humidification chamber 40, the humidification chamber 40 to the flame arrester 94, and the flame arrester 94 to the atomizer 7 (even extending to the user end) by the water (the make-up water and the electrolyzed water) in the hydrogen generator E. When a fire enters the interior of the hydrogen generator E from the end of the atomizer 7, the fire will be stopped by the flame arrestor 94. When a fire arises from the gas flow path between the humidification chamber 40 and the flame arrestor 94, the fire will be blocked by the additional water in the humidification chamber 40 and the flame arrestor 94. When a fire is generated from the electrolytic module 1, the fire will be blocked by the electrolyzed water in the water tank 2. Besides multi-interval fire retardance, multi-stage fire retardance can be achieved. For example: when a fire enters the hydrogen generator E from the atomiser 7, there is still additional water in the humidification chamber 40 to allow a second stage of fire retardation if the fire is not blocked by the flame arrestor 94. Thus, the safety of the hydrogen generator E can be sufficiently improved. It is understood that one of ordinary skill in the art can add and adjust flame arrestors 94 as needed to achieve more interval-type and staged flame arrestors, and the like, without limitation.

Referring to fig. 3 again, as shown in fig. 3, the cover of the condensing and filtering device 5 and the upper cover 30 of the integrated flow channel device 3 are hidden for clearly showing the interior of the condensing and filtering device 5, the gas inlet flow channel 35, the gas outlet flow channel 36 and the gas communication flow channel 37. The relative positions of the filter chamber 42, the gas inlet channel 35, the gas communication channel 37, the hydrogen cup 8, the gas outlet channel 36 and the atomizer 7 can be clearly seen in fig. 3. And the flow direction of the hydrogen-containing gas is indicated by solid arrows and dotted arrows. Under normal conditions, the hydrogen-containing gas sequentially flows from the filtering chamber 42, the gas inlet channel 35, the hydrogen cup 8, and the gas outlet channel 36 to the atomizer 7. In the state after the diversion signal is generated, the hydrogen-containing gas enters the gas outlet channel 36 from the gas inlet channel 35 through the gas communication channel 37 along the direction of the dotted arrow.

The condensation flow channel 50 of the condensation filtering device 5 is formed by a plurality of spacers 51, and the condensation flow channel 50 can contain filter cotton 52, and the filter cotton 52 can be at least one of steel wool and polyester synthetic fiber cotton. The filter cotton 52 is used to filter impurities in the hydrogen-containing gas, such as electrolyte or alkali mist. A heat sink (not shown) may be disposed on the filter cotton 52, and when the filter cotton 52 is tightly attached to the heat sink, the filter cotton 52 can transfer the heat energy in the hydrogen-containing gas to the outside to enhance the condensation effect. In practical applications, the filter cotton 52 may be an integrally formed structure, and the filter cotton 52 has corresponding holes at the positions where the spacers 51 are disposed. When the filter cotton 52 is embedded in the condensation flow channel 50, the filter cotton 52 can be directly coupled to the corresponding spacer 51 to improve the tightness between the condensation flow channel 50 and the filter cotton 52. In this way, it is ensured that the hydrogen-containing gas flowing through the condensation channel 50 can be filtered and condensed. The filter cotton 52 may also comprise a plurality of fiber cotton separating structures, or a combination of one or more steel wires and one or more fiber cotton.

The lower cover 31 of the integrated flow channel device 3 may have a movable and liftable structure 310 for forming a side edge enclosing the condensing and filtering accommodating space 320. The condensing and filtering device 5 can be placed in the condensing and filtering accommodating space 320 by the lifting structure 310, so that the condensing and filtering device 5 can be selectively embedded in the lower cover 31. Therefore, the hydrogen generator E can be opened or closed by the lifting structure 310 to facilitate the replacement of the condensing and filtering device 5 in the condensing and filtering accommodating space 320.

For a better understanding of the relative position and arrangement of the filter rod 60 and the filter chamber 42, please refer to fig. 5A to 6, in which fig. 5A is a cross-sectional view of the hydrogen generator E shown in fig. 3 along the line a-a', fig. 5B is a schematic view of the filter chamber 42 and the filter rod 60 of the hydrogen generator E shown in fig. 5A, and fig. 6 is an enlarged view of a part of the hydrogen generator E shown in fig. 5A. As shown in fig. 5A to 6, the filtering chamber 42 has a filtering chamber inlet 420 and a filtering chamber outlet 421, and the filtering chamber inlet 420 is coupled to the filtering communication passage 332, and the filtering chamber outlet 421 is coupled to the air flow passage 35. The filter rod 60 includes an air-blocking ring 600, and the filter rod 60 further has a plurality of filter inlets 601 and a plurality of filter outlets 602. The air blocking ring 600 is located outside the filter rod 60 to partition the filter chamber 42 into a space to be filtered 422 and a filtered space 423. Space to be filtered 422 is coupled to filter chamber inlet 420 and filter inlet 601, while space to be filtered 423 is coupled to filter outlet 602 and filter chamber outlet 421. When the hydrogen-containing gas enters the filtering chamber 42 from the filtering communicating passage 332, the hydrogen-containing gas flows through the filtering chamber inlet 420, the space to be filtered 422, the filtering inlet 601, the filtering rod 60, the filtered space 423 and the filtering chamber outlet 421 to the gas inlet passage 35 in sequence. Therefore, the filter rod 60 can form a flow channel by the structural design between the filter chamber 42 and the filter rod, and no additional pipeline is needed for connection, thereby achieving efficient space utilization and improving the tightness of the flow channel.

Referring to fig. 7, fig. 7 is a functional block diagram of an embodiment of an automatic diversion device 90 of a hydrogen generator E for selectively adjusting a gas flow direction according to the present invention. The hydrogen generator E of the present invention further comprises an automatic diversion device 90 for selectively adjusting the gas flow direction. The automatic diversion device 90 is used for selectively communicating the gas inlet channel 35, the hydrogen cup 8 and the gas outlet channel 36 or communicating the gas inlet channel 35, the gas communication channel 37 and the gas outlet channel 36 according to a diversion signal. In practice, the automatic diversion device 90 may be actuated by a solenoid valve.

Referring to fig. 8A and 8B together, fig. 8A is a schematic diagram illustrating a use state of the hydrogen generator E according to fig. 7 under a normal operation, and fig. 8B is a schematic diagram illustrating a use state of the hydrogen generator E according to fig. 7 after receiving a diversion signal. As shown in fig. 7, 8A and 8B, the inlet flow path 35, the gas communication flow path 37 and the outlet flow path 36 are located in the lower cover 31. The automatic diversion device 90 is coupled to the lower cover 31, and the automatic diversion device 90 is used for switching the flow channel according to the diversion signal of the monitoring device 91 so as to adjust the flow direction of the hydrogen-containing gas. As shown in fig. 8A, under normal operation, the monitoring device 91 can control the automatic diversion device 90 to connect the hydrogen cup 8 to the inlet channel 35 and the outlet channel 36, i.e. the inlet channel 35 is connected to the outlet channel 36 through the hydrogen cup 8, so that the hydrogen-containing gas generated from the electrolysis module 1 can flow through the inlet channel 35, the hydrogen cup 8 and the outlet channel 36 in sequence to flow to the atomizer 7 (as shown by the dashed arrows in the figure). The hydrogen-containing gas will be injected into the drinking water in the hydrogen cup 8 as it flows through the hydrogen cup 8 to form hydrogen-containing water. Then, the hydrogen-containing gas that is not dissolved in the drinking water is output from the hydrogen cup 8 and flows to the atomizer 7 through the outlet channel 36. As shown in fig. 8B, in another mode, the automatic diversion device 90 can communicate the gas inlet channel 35, the gas communication channel 37 and the gas outlet channel 36 according to the diversion signal sent by the monitoring device 91, and isolate the hydrogen cup 8 from the gas inlet channel 35 and the gas outlet channel 36. At this time, the gas inlet channel 35 is connected to the gas outlet channel 36 through the gas communication channel 37, so that the hydrogen-containing gas generated from the electrolysis module 1 flows through the gas inlet channel 35, the gas communication channel 37 and the gas outlet channel 36 in sequence to flow to the atomizer 7 (as shown by the dotted arrows in the figure). In one embodiment, the hydrogen-containing gas can be delivered between the humidification cup 4, the condensation filter device 5, the filter rod 60, the atomizer 7, the hydrogen cup 8 and the automatic diversion device 90 through the integrated flow channel device 3. Wherein, the humidifying cup 4, the condensing and filtering device 5, the atomizer 7 and the automatic diversion device 90 can be directly coupled with the lower cover 31.

In practical applications, when the hydrogen cup 8 injects the hydrogen-containing gas into the drinking water and the atomizer 7 vibrates and atomizes the hydrogen-containing gas to generate the health gas, low-frequency sound is generated. Low frequency sounds may not be noticeable in everyday daytime life, but by the time of night and night, such low frequency sounds may affect the sleep quality of the user. Therefore, the monitoring device 91 of the hydrogen generator E of the present invention is coupled to the automatic diversion device 90 for selectively generating a diversion signal to control the automatic diversion device 90. At night, the user can adjust the hydrogen generator E to the night mode, and the monitoring device 91 sends out a diversion signal to control the automatic diversion device 90, so that the gas communication channel 37 communicates with the inlet channel 35 and the outlet channel 36, so that the hydrogen-containing gas does not flow through the hydrogen cup 8. Further, in the night mode, the monitoring device 91 may also turn off the atomizer 7 to stop generating the atomizing gas, thereby avoiding the generation of low frequency sound. In another embodiment, when the night mode is released, the monitoring device 91 controls the automatic diversion device 90 to allow the hydrogen-containing gas to flow through the hydrogen cup 8 and control the atomizer 7 to generate the atomizing gas.

When the user uses the hydrogen generator E, the breathing tube connected to the hydrogen generator E for the user to breathe may be pressed due to the posture change of the user, thereby blocking the normal output of the hydrogen-containing gas from the hydrogen generator to the breathing tube. In order to avoid the problem that the flow channel in the hydrogen generator E is pressurized by the excessive hydrogen-containing gas and the machine body is exploded or damaged due to the abnormal output of the hydrogen-containing gas, the hydrogen generator E of the present invention further comprises a pressure sensor 92 to solve the problem. Referring to fig. 9, fig. 9 is a functional block diagram of a derivative embodiment of the hydrogen generator E according to fig. 7. As shown in fig. 9, a pressure sensor 92 is coupled to at least one of gas flow passage 35 and gas flow passage 36. The pressure sensor 92 is used for sensing the gas pressure in at least one of the inlet channel 35 and the outlet channel 36 equipped with the pressure sensor 92 and generating a pressure sensing signal. The monitoring device 91 is coupled to the pressure sensor 92 for controlling the operation of the electrolysis module 1 according to the pressure sensing signal. In practical applications, when the user presses the breathing tube, the hydrogen-containing gas in the gas channel cannot flow out from the hydrogen generator E, and the gas pressure in at least one of the inlet channel 35 and the outlet channel 36 is increased. When the pressure sensor 92 detects the gas pressure at the detection position to rise, the pressure sensor 92 will generate a pressure sensing signal to allow the monitoring device 91 to control the electrolysis module 1. The monitoring device 91 will control the electrolysis module 1 to temporarily generate the hydrogen-containing gas, so as to prevent the hydrogen generator E from exploding or being damaged due to the excessive hydrogen-containing gas in the gas flow channel expanding elements. In addition, the member that is pushed open by the hydrogen-containing gas also causes a problem that gas leakage is likely to occur when the hydrogen generator E is used at a later date.

The pressure sensor 92 can detect whether the pressure is changed by the user, and can also detect whether the gas pipeline inside the hydrogen generator E is smooth. The gas pressure in the gas flow passage gradually rises because the flame arrestor 94, the filter cotton 52, and the filter rod 60 in the hydrogen generator E may be gradually clogged due to long-term use. Therefore, the hydrogen generator E can detect the internal components by the pressure sensor 92 and remind the user to replace the internal components.

In one embodiment, the pressure sensor 92 may also send a pressure sensing signal containing a pressure detection value at regular intervals, and the monitoring device 91 monitors the change of the pressure sensing signal. If the pressure variation is abnormal (e.g. the pressure detection value exceeds the upper and lower thresholds, or the slope of the pressure variation is too large), the monitoring device 91 will suspend the electrolysis module 1 or increase the output of the hydrogen-containing gas generated by the electrolysis module 1. If the breathing circuit is unobstructed due to the posture change of the user, the monitoring device 91 may change back to the normal state according to the pressure sensing signal (e.g. the pressure sensing value returns to the range between the upper and lower thresholds, or the change slope of the pressure value becomes slow), and the monitoring device 91 will restart the electrolysis module 1 to generate the hydrogen-containing gas. In another embodiment, the hydrogen generator E further comprises a pressure relief device. When the monitoring device 91 suspends the electrolysis module 1, the pressure relief device is started at the same time to release the pressure in the gas flow channel, so that the occurrence of danger and the damage of the machine body are avoided.

Since the hydrogen generator E of the present invention has the hydrogen cup 8, when the hydrogen cup 8 is disengaged from the lower cover 31, the hydrogen-containing gas may flow out from the engagement between the hydrogen cup 8 and the lower cover 31, and the communication between the inlet flow passage 35, the hydrogen cup 8, and the outlet flow passage 36 is interrupted. In this regard, the hydrogen generator E of the present invention further comprises a discharge sensor 93 coupled to the hydrogen cup 8. Therefore, when the hydrogen cup 8 is disengaged from the lower cap 31, the removal sensor 93 generates a second diversion signal to allow the hydrogen-containing gas to flow to the gas outlet channel 36 through the gas communication channel 37 instead of flowing to the gas outlet channel 36 through the hydrogen cup 8, thereby solving the problem of the gas channel being interrupted.

In order to prolong the time of the hydrogen generator E generating the hydrogen-containing gas, the hydrogen generator E of the present invention further comprises a valve assembly 95 and a water guide assembly 96, so that when the electrolyzed water is insufficient, the electrolyzed water can be supplemented with the supplementing water from the humidification chamber 40, and when the supplementing water of the humidification chamber 40 is insufficient, the operator can supplement the water to the humidification chamber 40. For clarity of illustration of the valve assembly 95 and the water guide assembly 96, the following description will be divided into a gas flow path for supplying hydrogen-containing gas and a water flow path for replenishing electrolyzed water. Referring to fig. 10 to 13, fig. 10 is a functional block diagram of an embodiment of a valve assembly 95 of a hydrogen generator E capable of selectively adjusting a gas flow direction according to the present invention, fig. 11 is a schematic view illustrating a use state of the valve assembly 95 of the hydrogen generator E according to fig. 10, fig. 12 is a schematic view illustrating an external appearance of a refining apparatus 43 of the hydrogen generator E capable of selectively adjusting a gas flow direction according to the present invention, and fig. 13 is an exploded view illustrating a structure of the refining apparatus 43 according to fig. 12. As shown in fig. 10 to 11, the gas delivery channel 950 of the valve assembly 95 is coupled to the condensing channel 50 of the condensing and filtering device 5 and the humidification chamber 40 of the humidification cup 4 for delivering the hydrogen-containing gas. Further, the valve assembly 95 further has a condensation port 953 and a gas outlet 954 coupled to the gas flow passage 950. The condensation port 953 is at least coupled to the condensation and filtration device 5, and the gas outlet 954 is at least coupled to the humidification cup 4, so as to receive the hydrogen-containing gas from the condensation port 953 flowing through the communication chamber 41 and the condensation and filtration device 5 from the water tank 2, and output the hydrogen-containing gas from the gas outlet 954 to the humidification chamber 40 of the humidification cup 4. Thus, the hydrogen-containing gas can be transported between the humidification cup 4, the condensation and filtration device 5, the filter rod 60, the atomizer 7, the hydrogen cup 8, the automatic diversion device 90 and the valve assembly 95 through the integrated flow channel device 3. In one embodiment, the humidification cup 4, the condensation filter device 5, the atomizer 7, the automatic diversion device 90, and the valve assembly 95 may be directly coupled to the lower cover 31.

As shown in fig. 10 to 13, the humidification chamber 40 has a humidification space 400 for accommodating the supplementary water. The wetting chamber 40 further comprises a refining device 43, and the refining device 43 comprises a refining communication column 430, a coupling member 431 and a refining base 432. The tessellation communication column 430 is coupled to a gas delivery outlet 954, and the tessellation communication column 430 has a first tessellation flow path. The attenuating base 432 is coupled to an end of the attenuating communication rod 430 remote from the coupling gas outlet 954 by a coupling member 431 and is immersed in the make-up water. The refining base 432 further includes a refining cover 4320 and a refining base 4322, and the refining cover 4320 and the refining base 4322 are embedded to form a second refining flow channel. The first refining flow channel is communicated with the second refining flow channel. The refining cover 4320 has a plurality of refining holes 4321 for coupling the wetting space 400 and the second refining flow channel. Therefore, the hydrogen-containing gas enters from the gas output port 954, flows through the first refining flow channel, the second refining flow channel and the refining holes 4321, and finally enters the humidification chamber 40 to be injected with the supplementary water to humidify the hydrogen-containing gas. In one embodiment, the refining holes 4321 are centered at the intersection of the first refining flow channel and the second refining flow channel, the smaller the diameter of the refining hole 4321 closer to the center is, and the larger the diameter of the refining hole 4321 farther from the center is, so as to equally distribute the amount of the hydrogen-containing gas output from each refining hole 4321. In another implementation, the boundary between the first fining flow channel and the second fining flow channel is taken as the center, the aperture of the second fining flow channel closer to the center is not consistent with the aperture of the second fining flow channel farther from the center, for example, the aperture of the second fining flow channel is not uniform but gradually changed, so that the gas flow rate in the second fining flow channel can be changed, the hydrogen-containing gas is not concentrated in a specific second fining flow channel region and is output to the humidification chamber 40, and the second fining flow channel distributes the amount of the hydrogen-containing gas output from each fining hole 4321 as evenly as possible.

Referring to fig. 14 and 15, fig. 14 is a functional block diagram of another embodiment of a valve assembly 95 of a hydrogen generator E for selectively adjusting gas flow according to the present invention, and fig. 15 is a schematic diagram illustrating a usage state of the valve assembly 95 of the hydrogen generator E according to fig. 14. As shown in fig. 14 to 15, the valve assembly 95 further includes a water replenishing channel 951 coupled to the humidification chamber 40 of the humidification cup 4 and the condensation channel 50 of the condensation filter device 5 for conveying the water for replenishment. Further, the valve assembly 95 has a condensation port 953 and a refill inlet 955 coupled to the refill flow passage 951. The condensation port 953 is coupled to at least the condensation filter 5, and the make-up water inlet 955 is coupled to at least the humidification cup 4, such that make-up water is received from the humidification cup 4 and output from the condensation port 953. The make-up water then enters the water tank 2 via the condensation flow passage 50 of the condensation filter 5. When the make-up water passes through the condensation filtering device 5, the electrolyte filtered by the condensation filtering device 5 is flushed back and can enter the water tank, so that the service life of the condensation filtering device 5 can be prolonged, the consumption of the electrolyte can be reduced, and the service life of the hydrogen generator E can be prolonged. The timing of the back flushing of the make-up water can be performed when the electrolysis of the electrolysis module 1 is stopped.

In order to keep the air flow path and the water flow path clear and not interfere with each other, the valve assembly 95 further includes a first valve element 958. Please refer to fig. 11 and fig. 15. As shown in fig. 11 and 15, the first valve element 958 is configured to selectively block the gas flow passage 950 to disconnect the condensation port 953 from the gas flow outlet 954, and to open the water replenishing flow passage 951 to connect the condensation port 953 to the water replenishing inlet 955, or to block the water replenishing flow passage 951 to disconnect the condensation port 953 from the water replenishing inlet 955 and to open the gas flow passage 950 to connect the condensation port 953 to the gas flow outlet 954.

Optionally, the valve assembly 95 further comprises an exhaust channel 952 and a second valve element 959. The exhaust channel 952 couples the humidification chamber 40 and the water tank 2. Further, the valve assembly 95 has an exhaust inlet 956 and an exhaust outlet 957 connected by an exhaust flow passage 952. The exhaust inlet 956 is coupled to the exhaust channel 952 and the water tank 2, and the exhaust outlet 957 is coupled to the exhaust channel 952 and the humidification chamber 40, such that when the make-up water enters the water tank, the hydrogen-containing gas in the water tank 2 can enter the humidification chamber 40 through the exhaust channel 952. The second valve element 959 is coupled to the exhaust channel 952 for selectively communicating the exhaust channel 952 to communicate the humidification chamber 40 with the water tank 2.

In one embodiment, first valve element 958 and second valve element 959 are coupled together. When the first valve element 958 blocks the communication of the gas transmission passage 950 and opens the water supplement passage 951, the second valve element 959 opens the gas exhaust passage 952. While the first valve element 958 opens the gas transfer passage 950 and blocks the communication of the water replenishment passage 951, the second valve element 959 blocks the communication of the gas exhaust passage 952. In this way, during the process of generating the hydrogen-containing gas, the hydrogen-containing gas in the humidification chamber 40 does not enter the water tank 2 from the exhaust channel 952, thereby ensuring the correct flow direction of the hydrogen-containing gas. In practice, the first valve element 958 and the second valve element 959 may be solenoid actuated.

In order to promote the supply of the replenishing water in the humidification chamber 40 to the condensation flow passage 50 above the humidification chamber 40, the hydrogen generator E of the present invention further comprises a water guide assembly 96. As shown in fig. 14 and 15, the water guide assembly 96 includes a water guide passage 960 and a pump 961. The water guide assembly 96 is coupled to the humidification chamber 40 and the water replenishment flow channel 951. The pump 961 is coupled to the water flow channel 960, and is used for driving the make-up water in the humidification chamber 40 to flow through the water flow channel 960, the make-up water flow channel 951, and the condensation flow channel 50 to reach the water tank 2. I.e., the pump 961, can drive the make-up water in the humidification chamber 40 to the condensate filter 5 for back flushing the electrolyte and finally to the water tank 2 and/or the electrolysis module 1.

Referring to fig. 16A to 19 for a detailed description of the hydrogen water cup 8, fig. 16A is a sectional view of the hydrogen water cup 8 according to fig. 2 taken along line B-B ', fig. 16B is a sectional view of the hydrogen water cup 8 according to line B-B', fig. 17 is an enlarged view of a section C of the hydrogen water cup according to the dashed line of fig. 16B, fig. 18 is an exploded view of the water injection assembly 83 according to fig. 16B, and fig. 19 is a sectional view of the water injection assembly 83 according to fig. 18. As shown in fig. 16A and 16B, the hydrogen water cup 8 of the present invention includes a cup body 81, a cover 82, and a water filling assembly 83. The cup 81 has a receiving space 810 for receiving liquid or drinking water. The lid 82 is coupled to the cup 81, and the air inlet 820 and the air outlet 821 are disposed on the lid 82. The gas injection assembly 83 is accommodated in the accommodating space 810 and coupled to the gas inlet 820 for injecting the hydrogen-containing gas into the liquid or the drinking water to form the hydrogen-containing liquid or the hydrogen-containing water. The cover 82 further includes a water inlet (not shown) for supplying liquid to the hydrogen cup 8 and a water outlet cap 822 for outputting hydrogen-containing liquid, and the water outlet cap 822 covers the water inlet.

As shown in fig. 16A to 19, the gas injection assembly 83 includes a gas injection column 830 and a gas injection base 831. The gas injection column 830 is coupled to the gas inlet 820 and has a first gas injection flow passage 8300. The gas injection base 831 is positioned to be soaked in drinking water, and the gas injection base 831 further includes a gas injection base 8310 and a gas injection cover 8314. The gas injection seat 8310 is coupled to the gas injection column 830, and has a second gas injection channel 8312 and a plurality of gas injection holes 8313. The second gas injection channel 8312 is coupled to the first gas injection channel 8300, and the gas injection hole 8313 is coupled to the second gas injection channel 8312 (as shown in FIG. 17). The gas injection cover 8314 is embedded in the gas injection seat 8310 and has a micro bubble gas outlet structure 8315, so that the refined hydrogen-containing gas forms a plurality of micro bubbles in the drinking water. The micro bubble exhaust structure 8315 has a plurality of micro exhaust channels 8316 corresponding to the gas injection holes 8313, and the micro exhaust channels 8316 are coupled to the second gas injection channels 8312 through the gas injection holes 8313. When the hydrogen-containing gas enters the hydrogen cup 8 through the gas inlet 820, the hydrogen-containing gas flows through the first gas injection flow passage 8300, the second gas injection flow passage 8312 and the micro gas outlet flow passage 8316 in sequence, and forms a micro bubble state in the drinking water through the micro bubble gas outlet structure 8315.

As shown in fig. 18 and 19, the gas injection assembly 83 further includes a plurality of micro filter elements 832 respectively coupled to the micro gas outlet channels 8316. The micro filter 832 is used to filter the hydrogen-containing gas flowing through the micro gas outlet flow channel 8316 to ensure the quality of the hydrogen-containing gas injected into the drinking water is safe. In practical applications, the micro filter 832 may be an activated carbon filter, a drinking water filter, etc., but not limited thereto. In addition, the micro filter element 832 can further cut the hydrogen-containing gas into micro bubbles to increase the contact area with the drinking water, thereby increasing the concentration of the hydrogen-containing gas dissolved in the water.

As shown in fig. 17 and 19, the micro outlet flow channel 8316 is a hollow truncated cone structure having an upper hole 8317 and a lower hole 8318, wherein the area of the upper hole 8317 is larger than the area of the lower hole 8318 in one embodiment. The lower hole 8318 is located between the second gas injection flow passage 8312 and the micro gas outlet flow passage 8316, and the upper hole 8317 is located between the micro gas outlet flow passage 8316 and the accommodating space 810. The gas injection assembly 83 of the present invention increases the dispersion degree of the hydrogen-containing gas in the micro bubble state when injecting into the drinking water by the hollow truncated cone structural design. On the other hand, if the area of the upper holes 8317 is smaller than the area of the lower holes 8318, the hydrogen-containing gas in the micro-bubble state is collected to form a large-bubble state, and the contact area of the hydrogen-containing gas in the drinking water is reduced.

In order to evenly distribute the amount of the hydrogen-containing gas flowing out of each micro gas outlet channel 8316, so as to improve the output efficiency of the hydrogen-containing gas in the micro bubble state and the uniformity of the hydrogen-containing gas dispersed in the drinking water, the second gas injection channel 8312 of the gas injection assembly 83 of the present invention gradually increases from the coupling point with the first gas injection channel 8300 to the two ends of the gas injection seat 8310. The second gas injection channel 8312 can increase the flow rate of the hydrogen-containing gas flowing from the coupling point to the two ends by the design of the channel with a narrow middle part and wide two ends, so as to prevent most of the hydrogen-containing gas from being injected into the water from the coupling point, and thus all the micro gas outlet channels 8316 can not be fully utilized.

The gas injection assembly 83 further includes a fixing member 833. The fixing member 833 has a plurality of fixing holes 8330 for receiving and fixing the micro filter 832. The surface of the gas injection seat 8310 facing the gas injection cover 8314 has a groove 8311 for receiving the fixing member 833.

In one embodiment, the attenuating device 43 may also have a design like the gas injection assembly 83, in other words, the attenuating holes 4321 may also be designed as micro bubble blowing structures 8315 to enhance the attenuating effect.

Compared with the prior art, the hydrogen generator E of the invention is provided with the automatic diversion device 90, which can selectively allow the hydrogen-containing gas to flow through the hydrogen cup 8 according to the diversion signal and can also selectively control the action of the atomizer 7, thereby reducing the problem that the hydrogen cup 8 injects the hydrogen-containing gas and the atomizer 7 generates the atomizing gas and generates low-frequency sound. In addition, the hydrogen cup 8 of the present invention has a micro bubble gas outlet structure 8315 having a micro gas outlet flow passage 8316 with a hollow circular truncated cone structure, so that the refined hydrogen-containing gas can form micro bubbles in the drinking water and be injected into the drinking water to form hydrogen-containing water, and further the contact area of the hydrogen-containing gas in the drinking water is increased to increase the concentration of the hydrogen-containing gas dissolved in the water.

The integrated flow passage device comprises a plurality of passages which can be directly coupled with the atomizer, the condensation filtering device, the hydrogen cup and the like respectively; the integrated flow channel device is vertically stacked on the humidifying cup, the humidifying cup is vertically stacked on the water tank, and the condensing and filtering device in the integrated flow channel device can receive the hydrogen-containing gas output by the water tank through the communication chamber of the humidifying cup, so that the communication between the elements of the hydrogen generator E does not need to pass through an additional pipeline (such as a common air pipe or a water pipe), and the risks of air leakage and water leakage can be reduced.

The above detailed description of the embodiments is intended to more clearly describe the features and spirit of the present invention, and is not intended to limit the scope of the present invention by the embodiments disclosed above. On the contrary, it is intended to cover various modifications and equivalent arrangements included within the scope of the claims.
