Description

Electrolytic hydrogen suction device with heated aromatic gas suction function

The present invention relates to an electrolytic hydrogen suction device with a heating aromatic gas suction function that is portable and capable of safely and stably supplying hydrogen gas while maintaining generation of a predetermined amount of hydrogen gas during suction.

In recent years, the effectiveness of hydrogen has been demonstrated in experiments on various animal diseases such as neurodegenerative diseases and acute lung injury, as well as human clinical experiments on metabolic syndrome and diabetes, and various research on medical applications is being actively conducted. . Hydrogen removes only bad active oxygen (=hydroxyl radicals) from the body, which is the cause of various diseases such as acceleration of aging and arteriosclerosis and cancer, and does not have a negative effect on the tissues and cells of the body. There are a wide range of methods for taking drugs into the body, including intravenous administration, oral administration of aqueous solutions, and gas inhalation.

Among these methods, there is a method of ingesting hydrogen into the body by inhalation, and there is an electrolytic hydrogen inhalation device that electrolyzes electrolyzed water to generate hydrogen and inhales the hydrogen orally (Patent Document 1). 2), and based on the results of various clinical trials, the inventors have also provided a portable hydrogen suction device using a rechargeable battery that makes it easy to obtain health-promoting effects and can inhale an appropriate amount of hydrogen on a daily basis (Patent Document (See 3rd and 4th grade). Furthermore, in order to promote continuous suction of hydrogen, which is tasteless and odorless and lacks a feeling of suction, a portable hydrogen suction device with a heated aromatic gas suction function has been provided. In this case, it is possible to configure a portable hydrogen suction and supply device by combining an existing heating type circuit configuration with a power supply circuit for electrolysis for hydrogen generation, which can follow existing technology and is easy to develop.

In general, heated aromatic gas suction devices and electronic cigarette suction devices use electrical circuit configurations that are relatively easy to design, as the amount of suction required changes depending on the user's preference. The operation was performed at a "constant voltage" according to the electromotive force. Therefore, especially at a stage when the effectiveness of hydrogen was unclear, the electric circuit configuration of conventional heated aromatic gas suction devices was followed, and the amount of hydrogen supplied was not precisely managed.

On the other hand, as mentioned above, the inventor has provided the results of clinical trials regarding the health effects of hydrogen, and it was desired to develop and provide a hydrogen supply device that effectively obtains the health promoting effects based on those clinical trials. In other words, in order to obtain the medical and health-promoting effects of hydrogen based on clinical trials, an appropriate amount of hydrogen suction is required. It is necessary to maintain the amount of hydrogen generated at a predetermined amount. However, when electrolysis is performed at a "constant voltage", the resistance value increases due to deterioration of the electrodes and changes in the electrolyzed water, and the current value changes, so the amount of hydrogen supplied depends on the current value. In order to do this, it is necessary to increase the output voltage in response to the increase in resistance value, and if the maximum output voltage (rated) of the battery is exceeded, it will no longer be possible to output a "constant current" beyond that. Therefore, this has no choice but to limit the electrode configuration, and the lifespan of the electrode has to be the lifespan of the device.As a portable hydrogen suction device that is intended for regular use at home, etc., and is intended to be used continuously for a long period of time, It's inappropriate.

In addition, in portable hydrogen suction devices, the hydrogen generated from the electrolyzer is a flammable gas, so the selection of batteries and electrodes should be done at the initial design stage to limit the amount of hydrogen supplied to a safe concentration (4% or less). It is necessary to set the distance. However, in the case of a hydrogen suction device with a heated aromatic gas suction function, hydrogen is generated by electrolysis in the electrolytic cell, and at the same time separate steam is generated using a heated aromatic gas generation cartridge, etc., so the heat source ( There is always a heat source (heating element), and we do not want the hydrogen supply flow path to the suction part to be close to such a heat source. In particular, in the case of an electrolytic hydrogen suction device, a mixed gas of hydrogen and oxygen is generated, which requires a more sophisticated management design than that based on the combustible concentration of hydrogen. On the other hand, on the other hand, it is a portable device, and there is a strong demand for space saving, and in order to meet this demand, it is difficult to simply design the hydrogen supply channel to be far away from the heat source.

Japanese Patent Application Publication No. 2004-41949 Patent Application No. 2014-019640 International Publication WO2018/047889 International Publication Publication WO2018/151107

The present invention was created in view of the above circumstances, and is designed to maintain a predetermined amount of hydrogen supply in order to obtain the health-promoting effect of hydrogen suction even if it is small and space-saving and continues to be used on a daily basis. It is an object of the present invention to provide a specific configuration of an electrolytic hydrogen suction device with a heated aromatic gas suction function that can sufficiently ensure safety during the production of flammable hydrogen.

In order to solve the above problems, the electrolytic hydrogen suction device with heating aromatic gas suction function of the present invention has the following features:
A control means for controlling power supply from a built-in rechargeable battery when the power is on, a pair of positive and negative electrodes to which power is supplied or stopped from the battery by the control means, and the pair of positive and negative electrodes. an electrolytic cell capable of storing electrolyzed water, which is inserted into the electrolytic cell; an electrically heated aromatic gas emitting device to which power from the battery is supplied or stopped by the control means; A suction nozzle portion that guides and discharges hydrogen generated by electrolyzing electrolyzed water with positive and negative electrodes and aromatic gas generated by the aromatic gas discharge device to the outside,
The control means includes an electrode control circuit that maintains constant current power supplied from the battery to the pair of positive and negative electrodes.

The heated aromatic gas electrolysis hydrogen suction device of the present invention (hereinafter also simply referred to as "hydrogen suction device") is a hydrogen suction device that generates hydrogen by electrolyzing electrolyzed water in an electrolytic cell with a pair of positive and negative electrodes. It is a portable device that can simultaneously suck in aroma gas generated by a heated aroma gas emitting device, and it is controlled to maintain a "constant current" power from the battery that is supplied to the positive and negative electrodes that perform electrolysis. It has a circuit. By supplying a "constant current" to the positive and negative electrodes in this way, even if the output voltage from the battery changes depending on the amount of charge, or if the positive and negative electrodes deteriorate due to long-term use and the load resistance value increases. , the power value supplied to the positive and negative electrodes is maintained constant. In recent years, various clinical trials conducted by the inventors have revealed that it is important to secure a certain amount of hydrogen in order to obtain health promotion effects, and due to the nature of electrolysis, the amount of hydrogen depends on the current. Since the amount of hydrogen depends on the amount of hydrogen, the present invention makes it possible to ensure a desired amount of hydrogen even if the electromotive force of the battery and the resistance values of the positive and negative electrodes change. On the other hand, since the maximum output voltage of a battery is determined for each battery, even if a control configuration that maintains a "constant current" is adopted, deterioration of the positive and negative electrodes progresses and if the load resistance value R becomes excessive, the output current I = maximum output voltage Vmax/load resistance value R. Therefore, a "constant current" cannot be maintained. On the other hand, if this hydrogen suction device detects the current value and detects that the detected current value is lower than the predetermined current value, it can be determined that the positive and negative electrodes have reached their service life limits, and it is possible to determine when it is time to replace them. This hydrogen suction device is also advantageous in that it can provide indicators for judgment.

In addition, the electrolytic hydrogen suction device with heating aromatic gas suction function of the present invention has the following features:
a valve member disposed in the upper part of the electrolytic cell that opens against an elastic force when the internal pressure of the electrolytic cell increases and closes due to the elastic force when the internal pressure decreases;
Hydrogen generated by electrolyzing electrolyzed water with a pair of positive and negative electrodes in the electrolytic cell is separated from the aromatic gas emitting device and is guided to the nozzle portion. It is preferable.

According to this hydrogen suction device, when the electrolytic cell is filled with hydrogen and the internal pressure rises, it is equipped with a valve member that opens to the outside with elastic force and vents the hydrogen, so that hydrogen does not fill when not suctioning. , safety is ensured. As a result, there is no need to add a control configuration that supplies power to the positive and negative electrodes only when the electrolytic cell is in a sealed state to prevent it from being filled with hydrogen. It is possible to reduce the causes of electrical troubles due to miniaturization) and the adoption of complex controls.

In addition, according to this hydrogen suction tool, the hydrogen generated in the electrolytic cell is guided to the suction nozzle through a dedicated hydrogen guide channel, so flammable hydrogen is transported near the heating element such as the aromatic gas release tool. Since flammable hydrogen does not pass through the hydrogen suction device, a higher level of safety can be ensured even if the hydrogen suction device is made smaller. In summary, this hydrogen suction tool ensures safety at all times, regardless of whether it is not inhaling or inhaling.

Moreover, in the hydrogen suction tool of the present invention,
The control means is an electrode control circuit that stops the power supply from the battery to the pair of positive and negative electrodes and terminates electrolysis when the load resistance value of the pair of positive and negative electrodes becomes equal to or less than a predetermined value. It is preferable to have the following.

In order to increase the portability of this hydrogen suction device and make hydrogen suction available for regular use, the electrolytic cell needs to be made smaller, and the gap between the anodes also needs to be narrowed, which prevents corrosion from attaching to the electrodes. There is also an increased possibility that the positive and negative electrodes will be short-circuited. In order to prevent this, this hydrogen suction tool is equipped with an electrode control circuit that prevents short circuits between the pair of positive and negative electrodes in the electrolytic cell, which reduces the gap between the positive and negative electrodes, allowing the electrolytic cell to be made smaller. I have to. As a result, the load resistance values of the positive and negative electrodes are also reduced, so that the output voltage of the battery that can ensure a "constant current" can also be reduced, and the battery can also be made smaller.

Moreover, in the hydrogen suction tool of the present invention,
The control means includes an electrode control circuit that stops the power supply from the battery to the pair of positive and negative electrodes and terminates electrolysis when the load resistance value of the aromatic gas emitting device exceeds a predetermined value. is preferred.

Similar to the control configuration that aims to maintain a "constant current" by decreasing the load resistance value of the positive and negative electrodes mentioned above, it is controlled so that the load resistance value as an aromatic gas emitting device does not become excessive, and the positive current is maintained within the output voltage of the battery. A constant current to the negative electrode is ensured.

Moreover, in the hydrogen suction tool of the present invention,
The control means is configured to turn off or turn off the power to the hydrogen suction tool when a predetermined period of time has elapsed after the start of supply of power from the battery to the pair of positive and negative electrodes, or when the battery voltage of the battery has become equal to or lower than a predetermined value. Preferably, power supply from the battery to the pair of positive and negative electrodes is stopped.

According to this hydrogen suction tool, when hydrogen is generated by electrolysis, the power is turned off after a predetermined period of time has passed after the start of electrolysis, and it is necessary to restart the device to start electrolysis again. With this control configuration, safety can be ensured by not releasing more than necessary flammable hydrogen while ensuring the amount of hydrogen necessary to obtain the health-promoting effects of hydrogen suction. In addition, a "constant current" is ensured for the positive and negative electrodes, but "constant current" is not maintained unless the lowest electromotive voltage of the battery is ensured by charging, so if the battery voltage of the battery falls below a predetermined value, the power is turned off or Power supply to the positive and negative electrodes is stopped, and electrolysis ends.

Furthermore, in the hydrogen suction tool of the present invention,
comprising a gyro sensor that detects the inclination of the hydrogen supply tool,
The control means is configured to stop power supply from the battery to the pair of positive and negative electrodes when the gyro sensor detects a tilt of the hydrogen supply tool in either direction by a predetermined angle or more; It is preferable that the electrode control circuit has an electrode control circuit that restarts power supply from the battery to the pair of positive and negative electrodes when it is detected that the inclination of the electrode has become less than a predetermined angle.

According to this hydrogen suction device, by adopting a control configuration that terminates electrolysis when the main body is tilted at a predetermined angle or more regardless of direction, electrolyzed water leaks in the electrolytic cell and some of the positive and negative electrodes are not electrolyzed. It is possible to prevent the hydrogen supply amount from being insufficient to obtain the effective effect of hydrogen suction without being immersed in water.

According to the electrolytic hydrogen suction device with heated aromatic gas suction function of the present invention, although it is small and space-saving, it still requires a predetermined amount of hydrogen supply to obtain the health-promoting effect of hydrogen suction even when used on a daily basis. Furthermore, it is possible to sufficiently ensure safety during the production of flammable hydrogen.

Continuing on from FIG. 5, this is a flowchart showing the control configuration of the control board (control means) of the electrolytic hydrogen suction device with heating aromatic gas suction function.

Hereinafter, a typical embodiment of an electrolytic hydrogen suction device with a heated aromatic gas suction function according to the present invention will be described in detail with reference to FIGS. 1 to 6. Needless to say, there is no limit. Further, since each drawing is for conceptually explaining the present invention, dimensions, ratios, or numbers may be exaggerated or simplified as necessary to facilitate understanding. Furthermore, in the following description, the same or corresponding parts are denoted by the same reference numerals, and overlapping description may be omitted.

FIG. 1 illustrates and explains the overall configuration of an electrolytic hydrogen suction tool (hereinafter also simply referred to as a "hydrogen suction tool") 100 with a heated aroma gas suction function of the present invention. FIG. 1 is a block diagram schematically showing the overall configuration of the hydrogen suction tool 100, FIG. 2 is a six-sided view of a typical example of the hydrogen suction tool 100 shown in FIG. 1, and FIG. FIG. 4 is an exploded view showing the electrolytic cell in which hydrogen is generated, the lid member that plays a role in hydrogen propagation, and its surrounding components. A half-sectional view showing a part of the internal structure is shown. It goes without saying that the smoking and hydrogen suction device of the present invention is not limited to what is shown in the drawings, but also includes those in which the contents of the drawings and description are modified within the scope of common knowledge.

As shown in FIGS. 1 and 2, the present hydrogen suction device 100 includes a rechargeable battery 104 that is supplied with power via an external input terminal 122, an LED 116, a control means 117, an electrolytic cell 103, an aromatic gas discharge device 105, It is generally composed of a lid member 14 and a nozzle part 108. A pair of positive and negative electrodes 8a and 8b are arranged in the electrolytic cell 103. The positive and negative electrodes 8a and 8b are supplied with power from the battery 104 via a control board 117, and an LED 116 that displays the power supply status and the like is connected to the battery 4. The control board 117 includes a power supply means (power supply circuit) 117d, an electrode control circuit 117a that controls power supply to the positive and negative electrodes 8a and 8b via the power supply means 117d, and a power supply means (power supply circuit) 117d. A heater control circuit 117b that controls the power supply to the heater (evaporation chamber) in the aromatic gas emitting device 105, and an LED control circuit 117c that controls the power supply to the LED 116 via the power supply means 117d are provided. ing.

In addition, a pressure sensor switch 119 is provided on the attachment that supplies power to the aromatic gas emitting device 105, and when the lower end of the aromatic gas emitting device 105 presses the pressure sensor switch 119, the power supply means 117d of the control board 117 supplies the power to the battery 104. is supplied to the aroma gas emitting device 105.

Further, as will be described in detail later, when the user operates the operation button 118, the electrode control circuit 117d controls energization/cutoff to the pair of electrodes 8a and 8b in the electrolytic cell 103, and the power supply means 117d varies the amount of power supplied from the battery 104 to supply power to the positive and negative electrodes 8a and 8b. When power is supplied to the pair of positive and negative electrodes 8a and 8b, water stored in the electrolytic cell 103 is electrolyzed, and oxygen is generated on the positive electrode 8a side and hydrogen is generated on the negative electrode 8b side.

Hydrogen generated from the negative electrode 8b is guided to the nozzle part 108 via an attachment on the upper part of the electrolytic cell 103 and a dedicated hydrogen guide channel provided in the lid member 14. Further, oxygen generated from the positive electrode 8a is vented (details will be described later).

Further, when the pressure sensor switch 119 is turned ON, the aromatic gas emitting device 105 becomes in a state where the electric power can be supplied from the battery 104 to the heater in the aromatic gas emitting device 105 by the power supply means 117d, and the power is supplied. and heats the fragrance cartridge attached to the internal steam chamber, generating fragrance-containing vapor (also referred to as "fragrance gas"). Note that aromatic gases include not only general aromatics such as mint, but also gases that have a health-promoting effect such as xylitol and vitamins, as long as they can be released as a gas by heating.

· The aromatic agent-containing vapor generated by the aromatic gas discharge device 105 is discharged into the mouth by suctioning the nozzle part 8. At this time, due to the negative pressure generated by suction, hydrogen and aromatic gas pass through the hydrogen guide channel in the lid member 14 and the gap between the aromatic gas release device 105 and the nozzle part 108, and the hydrogen and aroma The gas mixes with the air inside the lid member 14 and is guided into the mouth.

Next, the electrolytic cell 103, the lid member 14, and surrounding members will be described with reference to the exploded view of FIG. The electrolytic cell 103 is composed of an electrolytic cell main body 1 and an electrolytic cell lid 3. The electrolytic cell main body 1 is a container for storing electrolyte solution extending in the vertical direction, and is an integrally formed container that is fluidly connected to each other internally, and as an example, here, the lower part has a shape that is smaller in diameter than the upper part. . The electrolytic cell main body 1 can be injected with water from an upper opening, and is closed by inserting a plate-shaped separator 5 with a through hole in the upper part of the opening and attaching an electrolytic cell lid 3. The electrolytic cell lid part 3 is a case that penetrates vertically, and has a two-stage shape in which the diameter of the lower hem part increases and the diameter of the upper part decreases. The electrolytic cell lid part 3 forms a bottom part by fixing the lower part to the separator 5 by a lock lever 7. Further, the opening at the top of the electrolytic cell cover 3 is formed into a counterbore shape in order to receive a first transmission member 2 of a permeation device to be described later.

In addition, since the lower part of the electrolytic cell body 1 is smaller in diameter than the upper part, even if the aqueous solution accumulated inside is electrolyzed and the amount of water stored is reduced, most of the pair of positive and negative electrodes 8 will remain in the electrolytic solution. Electrolyte accumulates to the extent that it is immersed in water. This reduces the air layer at the top of the electrolytic cell body 1 and ensures electrolysis performance, but on the other hand, even taking into account the presence of the separator 5, the level of the electrolyte has risen to the limit, and electrolysis When the viscosity increases, bubbles generated by electrolysis enter and remain in the air layer and the electrolytic cell lid 3.

Two pairs of anode and cathode electrodes (mesh electrodes) 8 are arranged vertically in parallel upward, forming anode and cathode respectively, and are supplied with power from the battery 104. Moreover, the upper part of the positive and negative electrodes 8 is larger than the lower part so as to correspond to the reduced diameter part and the enlarged diameter part of the electrolytic cell body 1. A rod-shaped titanium electrode 9 is connected to the lower end of the positive and negative electrodes 8 so as to stand up on the terminal board 24 for electrical connection. In order to shield the positive and negative electrodes 8 and the terminal board 24 from water while the positive and negative electrodes 8 are standing up, a socket 25 (made of resin such as silicone) is installed on the terminal board 24 and an O is installed around the titanium electrode 9. Rings 10 and 11 (made of resin such as silicone; hereinafter referred to as O-rings) are provided.

Additionally, a permeation device is attached to the top of the electrolytic cell lid 3. First, the first transmission member 2 is attached to the upper part of the electrolytic cell lid 3. The first permeable member 2 has a lower portion that is reduced in diameter and protrudes downward so as to fit vertically into the electrolytic cell lid portion 3, and an upper portion that is largely opened upward. The reduced diameter portion of the first transmission member 2 is closed at the bottom and connected to the opening at the top, and is formed to form a liquid pool. Further, the enlarged diameter part at the upper part of the first permeable member 2 is connected to the opening of the liquid pool on the side of the reduced diameter part described above, and has a through hole that is fluidly connected to the opening of the electrolytic cell lid part 3. The lower end of the through hole is inserted and connected using the opening of the electrolytic cell lid 3 as a counterbore. At this time, an O-ring 23 to prevent water leakage is disposed between the through hole of the first permeable member 2 and the opening of the electrolytic cell cover 3.

Further, a permeable membrane 12 is disposed in the through hole of the first permeable member 2 by a permeable membrane holder 6 to close the through hole. This permeable membrane 12 is a porous resin membrane (tetrafluoroethylene resin porous membrane (the same applies to the second permeable membrane 12 described later)) that has selective permeability that allows gas to pass through and blocks liquid while adjusting the internal pressure with micropores. be. First, in the first step, the permeable membrane 12 blocks the bubbles of the electrolytic solution that have reached the inside of the electrolytic cell lid 3. However, when the internal pressure inside the electrolytic cell body 1 increases, the permeable membrane 12 expands and the micropores expand, allowing the foamy electrolyte to permeate, or the gasified electrolyte permeates into the first permeable member 2. In order to prevent the electrolyte from penetrating into the first permeable member 2 and to prevent the hydrogen permeation rate from decreasing due to the pore diameter of the permeable membrane 12 being made too small, the first permeable member 2 is designed to overlook the electrolyte permeation to some extent. , the electrolyte is stored in the reduced diameter portion of the first permeable member 2 as a liquid reservoir.

Furthermore, a second transparent member 4 is attached to the upper part of the first transparent member 2. The second transparent member 4 opens downward and matches the upper opening of the first transparent member 2 to form an internal space. A through hole is formed in the upper part of the second permeable member 4 at a position that looks into the through hole of the electrolytic cell lid 3 and the through hole of the first permeable member 2. This through hole is closed with a permeable membrane 12 similar to the permeable membrane 12 of the first permeable member 2, and sealed with an O-ring 22. Like the permeable membrane 12 of the first permeable member 4, the permeable membrane 12 of the second permeable member 4 is also a porous resin membrane (in this case, a porous polytetrafluoroethylene resin membrane) that has selective permeability that allows gas to pass through and blocks liquid. are using.

Therefore, in the first stage, the penetration of the electrolyte into the electrolytic cell is generally blocked by the permeable membrane 12 of the first permeable member 2, but in the second stage, the electrolytic solution is further blocked by the permeable membrane 12 of the second permeable member 4. Prevents release to the outside. Note that the second permeable member 4 is provided with a hole for draining the electrolytic solution stored in the liquid reservoir of the first permeable member 2, and the hole is closed with a screw 13 via a packing 21. When draining, the screw 13 is removed to enable disposal of the electrolyte.

A lid member 14 is attached to the upper part of the second transparent member 4 from above. In addition to the suction nozzle 108, a through hole is provided above the permeable membrane 12 of the second permeable member 4 in the upper part of the lid member 14, and the valve shaft 17 is inserted into the through hole and closed. The tip of the valve shaft 17 is connected to a base 18 sandwiched between packings 18 by a pin 20, and the through hole is opened under normal conditions (when not suctioning) by the action of a spring 19, and the nozzle portion 108 is closed when suctioning the lid member. When negative pressure acts inside the dedicated hydrogen guide channel 30 (see FIG. 4) in the hydrogen guide channel 14, it closes. Therefore, during suction, the flammable hydrogen-containing air passes through the dedicated hydrogen guide flow path 30 and is guided to the nozzle part 108, without passing near the heating element such as the aromatic gas discharge device 105, and when not suctioned. This prevents hydrogen from filling up, ensuring safety. As a result, there is no need to add a control configuration that supplies power to the positive and negative electrodes 8 only when the electrolytic cell is in a sealed state to prevent it from being filled with hydrogen, and the control board 117 etc. can be miniaturized (as a result, this hydrogen suction tool It is possible to reduce the causes of electrical troubles due to miniaturization of 100 mm) and the adoption of complicated controls.

Next, the control circuit configuration of the control board (control means) 117 of the hydrogen suction tool 100 will be explained with reference to control flow diagrams (FIGS. 5 and 6).
For example, by long pressing the operation button 118 on the side of the hydrogen suction device 100, the power is turned on (STEP 1), and when the power is turned on, the power supply circuit (power supply means) 117d of the control board (control means) 117 starts to smell. The gas is supplied to the gas release tool 105, and the heating time and heating control are executed by the heating control circuit 117b (STEP 2). When the operation button 118 is pressed while the power of the hydrogen suction device 100 is turned on, power is supplied to the positive and negative electrodes 8, and the electrolyzed water in the electrolytic cell 103 is electrolyzed to generate hydrogen and oxygen (STEP 3 ~ STEP 4). Note that the battery 104 is charged by external power being supplied from the external input terminal 122, and the battery 104 is charged when the battery voltage reaches 4.25V to prevent overcharging, or when 11 hours have passed since charging started. If this occurs, charging will be stopped.

Electrolysis within the electrolytic cell 103 is performed by supplying a "constant current" to the positive and negative electrodes 8. This is to maintain an effective amount of hydrogen supply based on clinical trials even if the resistance value changes due to deterioration of the positive and negative electrodes 8, such as when used for a long period of time as described above. "Constant current" is a constant current circuit that uses voltage-current conversion, and typically uses (1) a circuit using a transistor, (2) a circuit using an operational amplifier, and (3) feedback control. Here, we will use a simple (1) circuit using transistors, or (2) a circuit using operational amplifiers, which has higher accuracy in ensuring a "constant current" and is less affected by temperature.

When a predetermined time (t1: 5 minutes in this embodiment) has passed after the start of electrolysis, the power is turned off (STEP 5 and circle Z in FIG. 5 to circle Z and STEP 14 in FIG. 6), and electrolysis starts again. It is necessary to restart (STEP 1). Furthermore, although a "constant current" is ensured in the positive and negative electrodes 8, "constant current" is not maintained unless the lowest electromotive voltage of the battery 104 is ensured by charging, so that the battery voltage V1 of the battery 104 is lower than a predetermined value ( For example, 3.2 V or less), the power is turned off and the electrolysis ends (STEP 6 and circle Z in FIG. 5 to circle Z and STEP 14 in FIG. 6). Although FIGS. 5 and 6 exemplify control in which the power is turned off when the electromotive voltage is below a predetermined value, a control configuration in which power supply to the positive and negative electrodes 8 is stopped and electrolysis is completed may also be used.

Further, for short circuit protection, if the load resistance value R of the aromatic gas discharge unit 105 is less than a predetermined value (R1: 1.8Ω in this embodiment), the power is turned off (STEP 15 to circle Z in FIG. 6). However, if it is confirmed that the electrolysis is operating normally, the electrolysis will operate normally (STEP 15 to circle Y in FIG. 6). Although not shown here, if the power is originally OFF, it will not turn ON.

Also, when the load resistance value R of the aromatic gas emitting device 105 exceeds a predetermined value (R2: 3.5Ω in this embodiment), the power is turned off (STEP 8 to STEP 10 to STEP 14). This is because if the load resistance value R of the aromatic gas emitting device 105 becomes too large, a constant current to the positive and negative electrodes 8 cannot be ensured within the output voltage of the battery 104. However, if a constant current is ensured and it is confirmed that the electrolysis is operating normally, the electrolysis will operate normally (STEP 10 to circle Y in FIG. 6).

In addition, in order to ensure the safety of the hydrogen suction device 100 in consideration of the flammability of hydrogen, in order to prevent the aromatic gas discharge part 105 from overheating, the heating time of the aromatic gas discharge part 105 is set to (1) a predetermined time t2. or (2) when a predetermined time t3 has elapsed since the previous time, the heater control circuit 117c stops the power supply to the aromatic gas discharge unit 105 (STEP11, STEP12, and STEP10 to STEP14). This is to prevent a decrease in safety due to overheating of the aromatic gas emitting section 105 by (1) limiting the heating time for one time and (2) limiting continuous use in a short period of time. However, if it is confirmed that the electrolysis is operating normally, the electrolysis will operate normally (STEP 15 to circle Y in FIG. 6). Although not shown in FIGS. 5 and 6, control is also performed to turn off the power when the temperature of the control circuit (control means) 117 reaches a predetermined temperature (for example, 80° C.) or higher.

In addition, this hydrogen supply device 100 is equipped with a gyro sensor (not shown), and the gyro sensor is tilted at a predetermined angle or more regardless of the direction of the main body (for example, 75 degrees or more (up to 15 degrees or less with respect to the horizontal direction)). ) is detected, the electrode control circuit 117a stops the power supply to the positive and negative electrodes 8, and the electrolysis ends (STEP13 to STEP9). This is to prevent leakage of electrolyzed water in the electrolytic cell 103 and failure to ensure a hydrogen supply amount sufficient to obtain an effective effect of hydrogen suction due to a portion of the positive and negative electrodes 8 not being immersed in the electrolyzed water. Note that, although not shown, when the gyro sensor detects that the tilt angle has returned to within the operable range, electrolysis resumes.

Furthermore, when the load resistance value R of the positive and negative electrodes 8 becomes equal to or less than the predetermined value R3, the electrode control circuit 117a stops the power supply to the positive and negative electrodes 8, and the electrolysis ends (STEP 16 to STEP 9). In order to increase the portability of the present hydrogen supply device 100 and to use hydrogen suction regularly, it is necessary to downsize the electrolytic cell 103, and it is also necessary to narrow the gap between the anode 8a and the anode 8b, which prevents corrosive substances from forming on the electrodes. There is also an increased possibility that the positive and negative electrodes 8 will be short-circuited due to adhesion. In order to prevent this, a control configuration is adopted that prevents the positive and negative electrodes 8 in the electrolytic cell 103 from being short-circuited. This control configuration not only reduces the size of the electrolytic cell 103 by narrowing the gap between the anode 8a and the cathode 8b, but also reduces the load resistance value, thereby reducing the output voltage of the battery 104 that can ensure a "constant current". This also contributes to miniaturization of the battery 104.
