[0048] A description will be given below of the electrolysis-type hydrogen gas suction tool 100 mainly with reference to the assembly exploded view in FIG. 1 and further with reference to the other drawings for the purpose of illustration.

[0049] As mentioned above, FIG. 1 shows a configuration example of each of the members of the present hydrogen gas suction tool 100. A main body cover 1 is a resin case having a battery reception portion 43 which is open upward, through which a battery 36 is inserted and embedded in a vertical direction from the opening, and an electrolysis tank reception portion 44 which is disposed in parallel with the battery reception portion 43 in a vertical direction and has such a shape that a diameter-reduced portion 45 in a lower portion of the electrolysis tank 10 can be inserted and fitted from the above. The battery 36 used here is preferably a rechargeable lithium battery.

[0050] The main body cover 1 has a shape which is long in the side of the battery reception portion 43 and is cut in such a manner that an upper portion is inclined laterally in the side of the electrolysis tank reception portion 44. In a bottom portion of the main body cover 1, a bottom portion of the battery reception portion 43 can be opened and closed by using a main body bottom cover 6 as a lid member, and the bottom portion of the battery reception portion 43 is closed by the main body bottom cover 6 after the battery 36 is inserted from the bottom portion when assembling. The main body bottom cover 6 is closed by a cross recessed head screw 38. Further, the main body cover 1 is provided with a space in which two control boards (electronic substrates) 33 and 42 are arranged in such a manner as to sandwich the battery 36 in both sides of a side portion of the battery reception portion 43 in the vertical direction, and the control board 33 in a side surface side of the main body cover 1 is a main control board, and controls an electric power supply from the battery 36 to the control board 42 in the electrolysis tank 10 side which supplies electric power to a suction portion 32 (an aroma generating device) and a mesh electrode 17 (an electrode plate).

[0051] A decorative laminate 9 is installed to the side surface of the main body cover 1 along a side surface in a longitudinal direction, and the decorative laminate 9 is provided with a button hole 9a through which an operation button 35 for the control board 33 can be seen, an LED hole 9b for light irradiation from an LED substrate 30, and a charge connector hole 9c for connecting a connector charging the battery 36 from an external power source, in this order from the above.

[0052] When pushing the operation button 35 three times, an electric power supply signal is transmitted to the control board 42 in the control board 33, and the electric power of the battery 36 is supplied to a pair of mesh electrodes (electrode plates) 17 via a substrate connector housing 31 and a pressure-bonding substrate 28 for a predetermined period of time. When the electric power is supplied to the mesh electrode 17, an electric power supply signal is transmitted to the LED substrate 30 in the control board 33, and the LED substrate 30 makes the LED emit light. As a result, a user can visually recognize a hydrogen gas generating state via the LED hole 9b. Pushing the operation button 35 three times is set to a condition for supplying the power source to the mesh electrode 17 because this condition is set as a safety condition for avoiding an erroneous electric power supply by unintentionally operating the button when the user puts the hydrogen gas suction tool 100 in a pocket while moving.

[0053] The two paired mesh electrodes 17 are arranged side by side longitudinally toward the above, respectively form positive and negative electrodes, and correspond to the electric power from the positive and negative electrodes of the battery 36. Further, an upper end of the mesh electrode 17 has a shape which is diagonally cut out in such a manner as to correspond to a boundary line between the diameter-reduced portion 45 and the water storage main body portion 46 of the electrolysis tank 10. A lower end of the mesh electrode 17 is raised up on a terminal substrate 28 and a rod-shaped titanium electrode 16 is coupled thereto in such a manner as to achieve an electrical connection. In order to shield the mesh substrate 17 and the terminal substrate 28 from water in a state in which the mesh electrode 17 is raised, there are provided a packing 13 (made of a resin such as silicone) which is installed on the terminal substrate 28, and an O-ring (made of a resin such as silicone, hereinafter refer also to as O-ring) which is attached to a periphery of the titanium electrode 16.

[0054] The electrolysis tank 10 is a container for water storage, and a diameter-reduced portion 45 and a water storage main body portion 46 are integrally formed in this order from the below and are fluidly connected to each other internally. The water storage main body portion 46 can open upward and water can be poured therefrom, and is semi-closed by attaching the electrolysis tank lid 12 thereto. The electrolysis tank lid 12 passes through up and down, and is provided with a through opening 12a which receives the umbrella valve 23 and a screw cap 14. The water storage main body portion 46 includes an outside portion 46a which forms an approximately flat side wall in a lateral direction from an upper end to a lower end and is coupled to an upper end of the diameter-reduced portion 45 as it is as shown in FIG. 3; an inside portion 46b in the main body cover 1 side which is formed in parallel to the outside portion 46a from an upper end to a central lower position; and a bottom portion 46c which is bent and inclined from the central lower position. The bottom portion 46c extends to an intermediate position in a lateral direction and is coupled to the upper end of the diameter-reduced portion 45.

[0055] Further, the diameter-reduced portion 45 is thinner than the water storage main body portion 46 as mentioned above, the upper end of the outside portion 46a in the side wall side is continuously connected as it is to the lower end of the outside portion 46a of the water storage main body portion 46 and extends to the lower end as shown in FIG. 3, and the upper end of an inside portion 45b of the diameter-reduced portion 45 in the main body cover 1 side is bent downward at a position in a leading end (an edge portion) of the bottom portion 46c of the water storage main body portion 46 and is connected so as to extend to the lower end in parallel to the inside portion 45b.

[0056] Further, at a connection position between the lower end of the outside portion 46a in the water storage main body portion 46 and the upper end of the outside portion 46a in the diameter-reduced portion 45, there is provided a partition plate 45d which is inclined approximately in the same manner as the bottom portion 46c of the water storage main body portion 46 and extends to the opening 45c. The partition plate 45d extends over an entire inner portion in a vertical direction on the page space of FIG. 3. Therefore, even in the case that the aqueous solution accumulated in the electrolysis tank 10 is electrolyzed and the water storage amount is reduced, water is always accumulated approximately in the entire area of the inner portion of the diameter-reduced portion 45. Specifically, even when the water storage amount is reduced and the air layer is generated partly within the electrolysis tank 10, the diameter-reduced portion 45 is filled with water in the normal standing state and the air layer is not generated until water storage amount is reduced greatly since the diameter-reduced portion 45 is first of all thinner than the water storage main body portion 46.

[0057] The air layer may be generated within the diameter-reduced portion 45 in the case that the present hydrogen gas suction tool 100 is inclined or transversely placed. However, even in the case that the water storage amount is reduced to some degree, water is filled in the diameter-reduced portion 45 in the case of the present electrolysis tank 10. Specifically, in the case of being inclined in the leftward direction on the page space of FIG. 3, the bottom portion 46c serves as a baffle plate and the air layer is formed in the inside portion 46b side of the water storage main body portion 46. On the contrary, in the case of being inclined to the rightward direction on the page space of FIG. 3, the partition plate 45d serves as a baffle plate and the air layer is formed only in the outside portion 46a side of the water storage main body portion 46. Therefore, the mesh electrode 17 arranged within the diameter-reduced portion 45 is always in contact with water entirely, and the hydrogen generation amount can be always secured even in the case that the user sucks transversely.

[0058] The upper end edge of the mesh electrode 17 is formed by being diagonally cut along the shape of the diameter-reduced portion 45 and the opening 45c in such a manner that the whole electrode is immersed into water within the diameter-reduced portion 45 Returning back to FIG. 1, the lower end of the electrolysis tank 10 is closed by an electrolysis tank bottom 11, the electrolysis tank bottom 11 is provided with a pair or through holes into which each of the mesh electrodes 17 is inserted, and the mesh electrode 17 passes through the through hole of the electrolysis tank bottom 11 and is positioned within the diameter-reduced portion 45 by inserting the diameter-reduced portion 45 of the electrolysis tank 10 into the electrolysis tank reception portion 44 of the cover main body 1.

[0059] A description will be given of the umbrella valve 23 which is installed to the through opening 12a of the electrolysis tank lid 12 in the upper end of the electrolysis tank 10. When the screw cap 14 having an opening in its above and passing through up and down is installed to the through opening 12a, a vent filter 18 is interposed between a hole in a bottom portion of the screw cap 14 and a bottom portion of the through opening 12a, and an O-ring 21 is inserted into a downward periphery of the screw cap 14. The bent filter 18 has a function of waterproofing and dustproofing while regulating the internal pressure in the opening of the screw cap 14 with minute holes. Further, the O-ring 21 shields, from water, between an outer peripheral wall of the opening in the screw cap 14 and an inner peripheral wall of the through opening 12a.

[0060] Further, the umbrella valve 23 (made of a raw material having a flexibility such as silicone) operating in an up-and-down direction is attached to the opening of the screw cap 14, and the umbrella valve 23 is operated to move upward and fluidly connects to the inside of the electrolysis tank 10 via the through hole in the bottom portion of the screw cap 14 and the through opening 12a of the electrolysis tank lid 12 when the user sucks the nozzle 5 (mentioned later) and the negative pressure acts upward. Therefore, when the user sucks the nozzle 5, the hydrogen gas rising and accumulated within the electrolysis tank 10 is discharged to the outside. On the contrary, in a state in which the user interrupts the sucking and the negative pressure does not act, the umbrella valve 23 is operated to move down and the through hole in the bottom portion of the screw cap 14 is closed to close the discharging of the hydrogen gas within the electrolysis tank 10.

[0061] The mixer 2 is attached from the above to the electrolysis tank lid 12 to which the screw cap 14 and the umbrella valve 23 are installed. The mixer 2 has a tubular member 2a which extends downward as shown in FIG. 3, and the tubular member 2a forms a flow channel which guides upward the hydrogen gas from the umbrella valve 23, by inserting a lower end of the tubular member 2a into the opening of the screw cap 14. An O-ring 20 is provided around an outer peripheral wall of the tubular member 2a, and seals a clearance gap between the inner wall of the opening of the screw cap 14 and the tubular member 2a of the umbrella valve 20.

[0062] The mixer 2 and the electrolysis tank lid 12 are fixed by attaching lock buttons 3 and 4. Each of the lock buttons 3 and 4 is pinched in a back and forth direction (a vertical direction on the page space of FIG. 3) at the clearance gap position in the up-and-down direction between the mixer 2 and the electrolysis tank lid 12 and snaps. Further, as shown in FIG. 3, the mixer 2 is provided in its upper portion with a flow channel 2b toward the nozzle 5 direction. The flow channel 2b is connected to the flow channel formed by the tubular member 2a, and guides the hydrogen gas as shown by an arrow in FIG. 3.

[0063] A description will be given of the aromatic heater portion 32 which generates the aromatic air.

[0064] First of all, a contact terminal 37 of the battery 36 is inserted into an upper end opening of the battery reception portion 43 in the main body cover 1. The contact terminal 37 is formed by connecting a bottom portion of a large-diameter cylinder and an upper portion of a small-diameter cylinder, and the bottom portion is inserted into an opening in an upper end of the battery reception portion 43 and the electric power is supplied from the battery 36 to the aromatic heater portion 32. The contact terminal 37 is fastened to a joint 8 from the above with a cross recessed head screw 38. The joint 8 is formed in such a manner that the bottom portion of the small-diameter cylinder is connected to an approximately large-diameter discoid upper portion, and the upper portion of the contact terminal 37 and the bottom portion of the joint 8 are fitted in a nested manner.

[0065] The aromatic heater member 32 is mounted on the upper surface of the joint 8, and is pinched by the joint 8 and the mixer 2 and is fixed to the main body cover 1 when attaching the mixer 2 mentioned above. The aromatic heater member 32 is a general-purpose device, and is structured such that the air with aroma is generated in an inner portion thereof and is discharged upward when the electric power is supplied. Further, the mixer 2 is provided with a tubular member 2c which extends downward in parallel to the tubular member 2a mentioned above, and an upper end of the aromatic heater portion 32 is connected to the tubular member 2c. Therefore, the air with aroma discharged from the aromatic heater portion 32 passes through the tubular member 2c as shown by an arrow in FIG. 3, and joins together with the hydrogen gas flowing out of the flow channel 2b via the tubular member 2a so as to be flowed into the nozzle 5 and be discharged into a mouth of the user.

[0066] The nozzle 5 is structured such that the approximately large-diameter discoid member in the bottom portion is integrally connected to the tubular member in the upper portion, and the bottom portion is installed onto the opening in a top surface which is fluidly connected to the tubular member 2c of the heater portion 32 in the mixer 2. As a result, the hydrogen gas from the flow channel 2b and/or the air with aroma from the tubular member 2c is discharged to the outer portion of the upper end from the nozzle 5. An O-ring 22 is arranged in a connection portion between the bottom portion of the nozzle 5 and the mixer 2, and the connection portion is sealed.

[0067] Further, the control board 33 controls the electric power supply from the battery 36 to the aromatic heater portion 32. As mentioned above, the electric power to the mesh substrate 17 is supplied for a predetermined time by pushing the button 35 attached to the main body cover 1 three times. In the meanwhile, when the button is held down, the control board 33 connects the contact terminal 37 under a condition that the electric power supply signal is not transmitted to the mesh electrode 17, so that the electric power from the battery 36 is supplied to the aromatic heater portion 32 for a predetermined time.

[0068] Therefore, in the case that the button 35 is pushed three times and the user sucks the nozzle 5, the hydrogen gas is discharged from the nozzle 5, and the user can enjoy sucking the hydrogen gas for a predetermined time (during the light emission of the LED substrate 30). In the case that the button 35 is held down during the discharging of the hydrogen gas, the user can enjoy sucking the hydrogen gas with aroma.

[0069] The description is given above of the embodiment by exemplifying the hydrogen gas suction tool according to the present invention. However, those skilled in the art can understand that the present invention is not limited to the embodiment, but the other modified examples and improved examples can be obtained within the range which does not deviate from the scope and teaching described in the claims and the description.

INDUSTRIAL APPLICABILITY

[0070] According to the electrolysis-type hydrogen gas suction tool of the present invention, a sufficient amount of hydrogen gas generation can be secured even in the case that the tool is inclined in a state in which moisture within the electrolysis tank is reduced, while securing a space for embedding a battery and securing the water shielding between the electrolysis tank and the battery even if the tool has the rechargeable battery and is compact and inexpensive so that the user can bring and freely carry with.
