An embodiment of a portable water supply apparatus according to the present invention will be described with reference to FIGS.
As shown in FIGS. 1 to 10, the portable water supply according to the first embodiment attaches a lid 20 to the water supply body 10 in a detachable manner, and allows the cartridge 30 to be replaced in the water supply body 10. It is stored.

  As shown in FIG. 2, the water main body 10 has a double structure in which a bottomed inner wall cylinder 12 is housed in a bottomed outer wall cylinder 11 and is excellent in heat insulation. . The outer wall cylinder 11 is transparent, and a predetermined cylindrical gap 13 is formed between the outer wall cylinder 11 and the inner wall cylinder 12, and a photograph, a card or the like can be inserted into the cylindrical gap 13 and enjoyed. Further, as shown in FIG. 3, the inner wall cylinder 12 is formed with an annular step portion 14 for restricting the position of a cartridge 30 to be described later on its inner peripheral surface, and the lid 20 can be attached and detached. The female screw portion 15 for integration is projected in a discontinuous manner at a required pitch. The female screw portion 15 is partially cut out from four female screws. And the said annular step part 14 and the said internal thread part 15 have the same height dimension so that the taking-out operation | work of the core for shaping | molding may not be prevented in the case of shaping | molding.

As shown in FIG. 1B, the lid 20 has a planar shape covering the opening of the water supply body 10, and has an upper annular rib 21 projecting along an upper surface edge thereof, and the upper annular A drinking mouth 23 and an air hole 24 are provided on the bottom surface of the recess 22 surrounded by the rib 21. An opening / closing cap 25 is rotatably attached to the bottom surface of the lid 20. The opening / closing cap 25 includes a sealing member 26 that can simultaneously open and close the drinking mouth 23 and the air hole 24.
As shown in FIG. 2, the lid 20 has a lower annular rib 27 projecting along a lower surface edge thereof, and an opening edge of the inner wall cylindrical body 12 at the base of the lower annular rib 27. An annular sealing material 28 that is in close contact with is attached. Further, as shown in FIG. 3, the lower annular rib 27 has a male thread portion 29 partially cut out from four male threads on its outer peripheral surface, and is projected discontinuously at a required pitch. The male screw portion 29 has a substantially L-shape by forming an extension portion (not shown) that prevents screwing in the opposite direction at the right end thereof. For this reason, by positioning and rotating the lid body 20 in the clockwise direction, the male screw portion 29 of the lid body 20 is screwed into the female screw portion 15 of the water feeder main body 10, thereby the water feeder. The lid 20 can be firmly fixed to the main body 10.

As shown in FIGS. 4 to 6, the cartridge 30 has a filter medium 80 (such as a purifying material) between a lower cup 40 and an upper cup 50 assembled vertically, with a lower partition member 60 and an upper partition member 65 interposed therebetween. FIG. 2) is filled. For convenience of explanation, the filter medium 80 is not shown in FIG.
A lower filter 70 is disposed between the lower cup 40 and the lower partition member 60, and an upper filter 71 is disposed between the upper cup 50 and the upper partition member 65.

  As shown in FIG. 7, the lower cup 40 is a bottomed cylindrical body in which three flat portions 41 are uniformly formed on the outer peripheral surface, and a circular hole 42 and an arc-shaped elongated hole 43 are concentrically formed on the bottom surface thereof. In addition, the position restricting protrusions 44 are radially provided. Further, the lower cup 40 has engaging ribs 45 projecting along the opening edge portion of the outer peripheral surface where the flat portions 41 are not provided.

As shown in FIG. 8, the upper cup 50 is a bottomed cylindrical body in which three flat portions 51 are uniformly formed on the outer peripheral surface, and the opening edge portion 52 is circular. Further, the upper cup 50 is formed with a plurality of round holes 53 in the half of the bottom surface thereof, and two arc-shaped elongated holes 54a and 54b are formed concentrically in the remaining half of the bottom surface. 55 is cut out. In particular, the handle 55 is easily hooked with a finger by providing a cut portion 54c in the arcuate elongated hole 54a on the inner side.
The upper cup 50 is provided with an engagement hole 56 on the outer peripheral surface of the outer peripheral surface where the flat portion 51 is not provided at a position where the upper cup 50 can engage with the engagement rib 45 of the lower cup 40. In addition, a positioning rib 57 is provided above the engagement hole 56.
The upper cup 50 is provided with a substantially arc-shaped position restricting rib 58a on the back side of the bottom surface thereof.

  As shown in FIG. 9, the lower partition member 60 has a planar shape that can be disposed on the bottom surface of the lower cup 40, and a support shaft 61 projects from the center of the lower partition member 60. The rectangular through holes 62 are formed radially at a required pitch.

  As shown in FIG. 10, the upper partition member 65 has a planar shape that can cover the opening of the lower cup 40, and a shaft hole 66 that fits the tip of the support shaft 61 is provided at the center thereof. In addition, rectangular through-holes 67 are radially formed around the shaft hole 66 at a required pitch. Further, the upper partition member 65 has an engaging claw portion 68 formed along the outer peripheral edge portion thereof.

The lower filter 70 has a planar shape that can be disposed on the bottom surface of the lower cup 40. For example, a metal mesh, a resin mesh, a sheet-like activated carbon, a fibrous activated carbon, or the like can be used in addition to a nonwoven fabric.
For example, the roughness of the nonwoven fabric is preferably 10 μm to 500 μm, particularly preferably 100 μm to 200 μm. When the roughness of the mesh is less than 10 μm, the generated hydrogen gas accumulates in the lower layer of the filter medium, forms a gas film, and enters a so-called gas-engaged state that hinders the filtering operation, and cannot be filtered. Moreover, when it exceeds 500 micrometers, it is because an unnecessary solid substance cannot be filtered and the role of a filter will no longer be fulfilled.

The upper filter 71 has a planar shape that can cover the bottom surface of the upper partition member 35. For example, a nonwoven fabric, a metal mesh, a resin mesh, a sheet-like activated carbon, a fibrous activated carbon, or the like can be used.
For example, the upper filter made of fibrous activated carbon is preferably 1 μm to 500 μm, particularly 10 μm to 100 μm. This is because if the roughness of the eyes is less than 1 μm, the time required for filtration becomes too long. Moreover, when 500 micrometers is exceeded, it is because the free chlorine contained in a tap water will flow down as it is before it decomposes | disassembles into a chlorine ion with the activated carbon of a filter medium.

The filter medium 80 includes, in addition to filtering and purifying raw water, eluting components dissolved in the raw water, or generating hydrogen and ozone dissolved in the raw water from the raw water. Specifically, for example, in addition to a purification material that purifies raw water such as activated carbon and ion exchange resin, it may be tea leaves, herbs, medicinal stones, coffee, metal magnesium that generates hydrogen water, and the like.
Further, in this embodiment, the lower filter is rougher than the upper filter. For this reason, for example, hydrogen gas generated from the filter medium flows out downward without accumulating in the lower layer of the filter medium and forming a gas film. As a result, there is an advantage that the hydrogen gas is efficiently dissolved in water and the filtration time can be shortened.

When magnesium is used as the filter medium, the dissolved hydrogen concentration is affected by the surface area of magnesium, the flow rate of raw water passing through, the time required for passage, and the like. For this reason, it is necessary to select the shape of magnesium appropriately as needed. For example, a plate shape (punching metal shape) in which a large number of through-holes are formed in addition to a grain shape, a lump shape, or a chip shape such as canna scraps. Can be mentioned.
As a granular shape or a lump shape, a particle size of 0.1 mm to 5 mm, particularly 0.5 mm to 1 mm is preferable. If it is less than 0.1 mm, the reaction is vigorous and pulverizes early, so the life is short. If it exceeds 5 mm, the reaction surface area with water is small and hydrogen water having a desired hydrogen concentration is obtained. Because it is not possible.
As the cutting shape, a width of 0.5 mm to 10 mm, particularly 1 mm to 2 mm is preferable. If it is less than 0.5 mm, the reaction with water is quick and finely pulverized early, and the lifetime is short. If it exceeds 10 mm, the reaction surface area with water is small, and hydrogen water having a desired hydrogen concentration is obtained. It is because it cannot be obtained.
As a punching metal shape, through-holes having a diameter of 0.1 mm to 5 mm may be formed at a pitch of 0.2 mm to 10 mm in plate-like magnesium having a thickness of 1 mm to 3 mm. This is because if the diameter is less than 0.1 mm, processing becomes difficult, and if the diameter exceeds 5 mm, the reaction surface area with water decreases, and hydrogen water having a desired hydrogen concentration cannot be obtained. Further, if the pitch is 0.2 mm, processing becomes difficult, and if the pitch exceeds 10 mm, the reaction surface area with water decreases, and hydrogen water having a desired hydrogen concentration cannot be obtained.

  Therefore, after the lower filter 70 and the lower partition member 60 are sequentially assembled to the lower cup 40, the filter medium 80, for example, magnesium is charged. Then, the upper surface of the filter medium 80 is covered with the upper partition member 65, and the shaft hole 66 of the upper partition member 65 is fitted to the support shaft 61 of the lower partition member 60. Next, after positioning the upper filter 71 on the upper partition member 65, the engagement ribs 45 of the lower cup 40 and the engagement claws 68 of the upper partition member 65 are engaged with the engagement holes 56 of the upper cup 50. By integrating, the cartridge 30 is completed. At this time, the flat portion 41 provided on the outer peripheral surface of the lower cup 40 and the flat portion 51 provided on the outer peripheral surface of the upper cup 50 are aligned in the same direction.

  Then, as shown in FIG. 3, the water supply main body 10 is accommodated with the cartridge 30, and the positioning rib 57 of the cartridge 30 is engaged with the annular step portion 14 of the water supply main body 10, thereby The cartridge 30 is supported in the main body 10 in a suspended state. Next, the lid body 20 is positioned on the water supply body 10 and the lid body 20 is rotated in the clockwise direction. Thereby, the male screw portion 29 of the lid body 20 is screwed into the female screw portion 15 of the water feeder main body 10, and the annular sealing material 28 of the lid body 20 is in close contact with the opening edge of the water feeder main body 10, Assembly work is completed.

  At this time, as shown in FIG. 2, a gap formed between the inner peripheral surface of the water supply main body 10 and the flat portions 41 and 51 of the cartridge 30, and the inner peripheral surface of the lower annular rib 27 of the lid body 20. And an annular gap formed between the opening edge portion 52 of the upper cup 50 and the flow passage 19 is formed. For this reason, the smooth inflow and outflow of the air and the stored water 81 are possible.

  Then, opening the opening / closing cap 25 of the lid 20, for example, when tap water is injected from the drinking mouth 23 of the lid 20, the upper cup 50, the upper filter 71 (not shown), and the upper partition member 65, Passes through the filter medium 80, which is magnesium. For this reason, the generated hydrogen is dissolved in water, and the hydrogen water is stored in the water supply body 10, while the air remaining in the water supply body 10 is in the air passages 24 and the air holes 24 of the lid 20. Spills through.

When the water supply main body 10 is tilted, the hydrogen water flows into the gap formed between the flat portions 41 and 51 of the cartridge 30 and the inner wall cylindrical body 12 and the lower annular rib 27 of the lid 20. It passes through at least one flow passage 19 including an annular gap formed between the peripheral surface and the opening edge 52 of the upper cup 50, and flows out from the drinking mouth 23 of the lid 20. On the other hand, since the outside air flows in through the remaining other flow passage 19, it is possible to drink hydrogen water smoothly.
In particular, according to the present embodiment, the three flow passages 19 can be formed evenly even if the cartridges 30 are assembled randomly in the water supply body 10. For this reason, there exists an advantage that water can be taken in and out smoothly in any case of water injection work and water absorption work.

As shown in FIG. 11, the second embodiment is substantially the same as the first embodiment described above, and the difference is that the shape of the upper cup 50 of the cartridge 30 is different.
In the upper cup 50 according to this embodiment, as shown in FIG. 11B, round holes 53 are formed radially on the entire bottom surface of the upper cup 50.
According to this embodiment, there exists an advantage that a tap water passes the filter medium 80 uniformly. The other parts are substantially the same as those in the first embodiment, and the same parts are denoted by the same reference numerals and the description thereof is omitted.

As shown in FIGS. 12 and 13, the third embodiment is substantially the same as the first embodiment described above, and is different from the outer peripheral surfaces of the lower cup 40 and the upper cup 50 of the cartridge 30 that face each other. A pair of flat portions 41 and 51 are formed in the same position.
According to the present embodiment, as shown in FIG. 12B, the gap formed between the flat portions 41, 51 and the inner peripheral surface of the inner wall cylinder 12, the opening edge 52 of the upper cup 50, and the lid body A gap formed between the lower annular ribs 20 and the lower annular ribs 20 communicates to form a pair of flow passages 19. For this reason, while the stored water 81 flows out smoothly from the drinking mouth 23 of the lid 20 through one of the flow passages 19, outside air flows into the water supply body 10 from the other flow passage 19. For this reason, the hydrogen water stored in the water supply main body 10 can be drunk smoothly.

As shown in FIGS. 14 and 15, the fourth embodiment is substantially the same as the first embodiment except that a flow passage 19 is provided in the cartridge 30 and a ball valve is provided in the flow passage 19. 47 is housed in a rollable manner.
That is, as shown in FIG. 15C, the lower cup 40 constituting the cartridge 30 is integrally formed with a cylindrical partition wall 46 penetrating vertically at the corner thereof to form the flow passage 19 and the flow passage. A ball valve 47 is accommodated in 19 so as to roll up and down. Further, the engagement rib 45 formed along the upper opening edge of the outer peripheral surface of the lower cup 40 is the engagement rib 45 formed along the lower opening edge of the inner peripheral surface of the upper cup 50. The receiving part 50b is locked and integrated.
The lower filter 70 and the upper filter 71 (not shown) are also formed with notches for avoiding the cylindrical partition wall 46 of the lower cup 40.
The upper cup 50 is provided with a cross-shaped retaining portion 58b at a position corresponding to the opening of the cylindrical partition wall 46. Further, the upper cup 50 is formed with positioning ribs 57 along the opening edges thereof, and a pair of air vent notch grooves 50a and 50a are formed in the vertical direction on the outer peripheral surface thereof.
The other parts are almost the same as those of the first embodiment, and the same parts are denoted by the same reference numerals and the description thereof is omitted.

  Therefore, the ball valve 47 is accommodated in the cylindrical partition wall 46 of the lower cup 40, and the lower filter 70 and the lower partition member 60 are sequentially accommodated and positioned. Then, after assembling the filter medium (not shown), the upper partition member 65, and the upper filter (not shown), the upper cup 50 is assembled to the lower cup 40 and integrated. At this time, the engagement rib 45 of the lower cup 40 and the engagement claw portion 68 of the upper partition member 65 are engaged with the engagement receiving portion 50 b of the upper cup 50.

According to the present embodiment, as in the first embodiment, when the user injects raw water from the drinking mouth 23 of the lid 20, the raw water is the upper cup 50, the upper filter 71 (not shown), and the upper partition member. It passes through a filter medium (not shown) via 65 and is stored in the inner wall cylinder 12. At this time, since the inside of the cylindrical partition wall 46 is closed by the ball valve 47, the raw water does not pass through.
When the user tilts the water supply body 10, the ball valve 47 rolls in the flow passage 19, and when hydrogen water flows in from the lower opening of the flow passage 19, the cross-shaped shape of the upper cup 50 is formed. It flows out from the retaining portion 58 b and can be taken from the drinking mouth 23 of the lid 20.

As shown in FIGS. 16 and 17, the fifth embodiment is substantially the same as the first embodiment except that the upper opening of the flow passage 19 provided in the cartridge 30 is connected to the opening / closing valve 59. It is the point which opened and closed with.
That is, as shown in FIG. 17D, the flow path 19 is formed in the lower cup 40 constituting the cartridge 30 by integrally forming a cylindrical partition wall 46 penetrating vertically at the corner. Further, an engagement rib 45 is formed along the opening edge of the outer peripheral surface of the lower cup 40.
The lower partition member 60 and the upper partition member 65 are formed with notches for avoiding the cylindrical partition wall 46.
The lower filter 70 and the upper filter 71 (not shown) are also formed with notches for avoiding the cylindrical partition wall 46 of the lower cup 40.
Further, the upper cup 50 is provided with an opening / closing valve 59 at a position corresponding to the upper opening of the cylindrical partition wall 46 so as to be rotatable. The upper cup 50 is provided with positioning ribs 57 along the opening edge portion of the outer peripheral surface thereof, and the engagement receiving portion along the lower opening edge portion of the inner peripheral surface thereof. 50b is provided.

According to this embodiment, when the user injects tap water from the drinking mouth 23 of the lid 20, the filter medium (not shown) is passed through the upper cup 50, the upper filter 71 (not shown) and the upper partition member 65. To generate hydrogen water. At this time, since the on-off valve 59 closes the flow passage 19, all tap water passes through the filter medium, so that a cartridge with high hydrogen generation efficiency is obtained.
When the user tilts the water supply body 10, the hydrogen water flows into the flow passage 19, pushes the on-off valve 59, and flows out, so that the hydrogen water can be drunk from the drinking mouth 23 of the lid 20. it can.

The cartridge 30 illustrated in the first embodiment is filled with 13 grams of machined magnesium having a width of around 5 mm, and a carbon fiber nonwoven fabric (2 sheets) is used as an upper filter, while a nonwoven fabric (1 sheet) is used as a lower filter. Incorporated. The cartridge 30 was accommodated in the water supply body 10. Subsequently, 220 ml of tap water was poured into the cartridge to obtain hydrogen water, which was taken out and the dissolved hydrogen concentration was measured.
Thereafter, the same test was repeated irregularly during 10 days, and the dissolved hydrogen concentration was measured each time. The measurement results are shown in the graph of FIG.

  As is apparent from FIG. 19, hydrogen water having a high dissolved hydrogen concentration of 350 ppb was obtained at the first time, and thereafter, the dissolved hydrogen concentration tended to decrease, but stable hydrogen water was obtained at a dissolved hydrogen concentration of around 200 ppb. It was found that

  In the above-described embodiment, various embodiments for forming the flow path are described separately, but it is needless to say that these may be appropriately combined as necessary. For example, it is needless to say that the third embodiment or the fourth embodiment may be combined with the first and second embodiments.
