[0031] (Example 1: Basic structure of the silver ion water generation spray device)

[0032] Figure 1 1 is an exploded perspective view showing the appearance of a silver ion water generating and spraying device (container assembly, metal ion water generating device) 1 according to an embodiment of the present invention. In this embodiment 1, the basic structure of the silver ion water generating and spraying device 1 is described. Figure 1 As shown, the silver ion water generating and spraying device 1 is composed of a spraying container (container, metal ion water generating container) 10 and a stand (support) 20 for mounting the spraying container 10. The spraying container 10 is a container having a nozzle 11, and the silver ion water generated and stored in the container can be sprayed from the nozzle 11. In addition, although silver ions are exemplified as the generated metal ions, it is not particularly limited as long as it is a certain metal ion that can generate antibacterial effects, and copper or zinc, etc., can also be used in addition to silver.

[0033] In the spray container 10, a silver electrode portion (electrode portion) 351 is provided at a position that contacts (is soaked in) water when water is stored in the container (see Figure 8 ). When the spray container 10 is placed on the stand 20, the silver electrode portion 351 of the spray container 10 can be powered from the power supply unit of the stand 20. That is, the spray container 10 is placed on the stand 20 and the silver electrode portion 351 is powered. By passing electricity between the electrodes, silver ions are eluted from the silver electrode portion 351 into the water, and silver ion water is generated in the spray container 10. When the silver ion water is generated in the spray container 10, the user can spray the silver ion water from the spray container 10 by simply picking up the spray container 10. In the case of Figure 1In the silver ion water generating and spraying device 1 shown, by pressing the operating button (operating unit) 21 provided on the stand 20 while the spraying container 10 is placed on the stand 20, power supply to the silver electrode portion 351 can be started (starting to generate silver ion water).

[0034] In the silver ion water generating and ejecting device 1 according to the first embodiment, silver ions can be generated by passing electricity between the electrodes of the silver electrode portion 351 , so that high-concentration silver ion water can be easily generated in a short time.

[0035] In addition, the spray container 10 itself does not have a power supply unit, but the pedestal 20 has a power supply unit. As a result, the spray container 10 can be made lighter, and the safety of the user when spraying silver ion water can be improved (to prevent electric shock). In addition, when the spray container 10 is accidentally submerged in water during use, the power supply circuit will not be damaged. Furthermore, the spray head 11 and the silver electrode part 351 consumed in daily use in the spray container 10 can also be replaced and used as a whole.

[0036] As the power source of the pedestal 20, either an external power source (commercial power source) or an internal power source (battery) may be used, but the external power source (commercial power source) is more preferably used. When the external power source is used as the power source of the pedestal 20, explosions caused by battery short circuits due to water leakage or the like can be avoided. In addition, since the power source voltage can be made constant by using an external power source, erroneous operations caused by voltage fluctuations can be avoided.

[0037] For the power supply from the pedestal 20 to the spray container 10, either the contact power supply method or the contactless power supply method may be used, but the contact power supply method is preferably used from the viewpoint of cost and efficiency. This is because in consideration of the fact that in the daily use of the silver ion water generating spray device 1, a large amount of water will not splash on the outside of the pedestal 20 and the spray container 10, and the necessity of using the highly waterproof contactless power supply method is low.

[0038] However, since a small amount of water may fall from the spray container 10 and splash onto the stand 20, it is preferable to take measures against this, especially when using the contact power supply method. Figure 2 As shown, it is preferable to set the front end of the nozzle head 11 to be located outside the outer periphery of the base 20 when viewed from above. At this time, no matter in which direction the spray container 10 is arranged on the base 20, the front end of the nozzle head 11 is located outside the outer periphery of the base 20. Thus, even if the silver ion water attached to the front end of the nozzle head 11 drips, it is possible to prevent the dripping silver ion water from splashing onto the base 20.

[0039] (Example 2: Contact structure between the spray container and the base)

[0040] In the second embodiment, the contact structure between the spray container 10 and the base 20 of the silver ion water generating spray device 1 is described. Here, the power supply from the base 20 to the spray container 10 is based on the premise of using the contact power supply method.

[0041] Figure 3 The drawings show the container-side contact portion 12 formed on the bottom surface of the spray container 10, (a) is a bottom view of the spray container 10, and (b) is an enlarged perspective view of the vicinity of the bottom of the spray container 10 as viewed from obliquely below. Figure 4 The figures show a pedestal-side contact portion (holding portion) 22 formed on the upper surface of the pedestal 20, (a) is a top view of the pedestal 20, and (b) is a perspective view of the pedestal 20 viewed from obliquely above.

[0042] like Figure 3 and Figure 4 As shown, the container side contact portion 12 of the spray container 10 is formed in a concave shape on the bottom surface of the spray container 10, and the base side contact portion 22 of the base 20 is formed in a convex shape on the upper surface of the base 20. Therefore, when the spray container 10 is arranged on the base 20, the concave and convex parts of the container side contact portion 12 and the base side contact portion 22 can be fitted to position the spray container 10 on the base 20. By positioning the spray container 10 on the base 20 in this way, the contact between the container side contact portion 12 and the base side contact portion 22 can be made stable (power supply can be performed reliably).

[0043] A plurality of notches 121 are formed at equal angles along the outer periphery of the container-side contact portion 12. In addition, a plurality of protrusions 221 are formed along the outer periphery of the stand-side contact portion 22. Thus, when the spray container 10 is placed on the stand 20, the notches 121 and the protrusions 221 are engaged with each other, thereby preventing the spray container 10 from rotating on the stand 20. Thus, mutual friction between the contact points between the container-side contact portion 12 and the stand-side contact portion 22 can be prevented.

[0044] like Figure 3 As shown in the figure, the container side contact part 12 of the spray container 10 has a circular terrace part 122 with a flat top surface at its center, and has a circular annular flat surface part 123 around the circular terrace part 122 (inside the notch 121). The circular terrace part 122 and the circular annular flat surface part 123 are arranged in a concentric circle shape, and the top surface of the circular terrace part 122 and the circular annular flat surface part 123 are at different heights. When the spray container 10 is placed on the pedestal 20, the top surface of the circular terrace part 122 is at a lower position than the circular annular flat surface part 123.

[0045] At least one first contact point 124 is disposed on the top surface of the circular platform 122 (at Figure 3 At least one second contact point 125 (in Figure 3In this case, one of the first contact point 124 and the second contact point 125 becomes the contact point on the positive side, and the other becomes the contact point on the negative side. Figure 3 In the example shown, leaf spring contacts are used at the first contact 124 and the second contact 125 to obtain appropriate contact pressure. However, the present invention is not limited thereto, and for example, spring probes may be used at the first contact 124 and the second contact 125. In addition, the contact exposed to the outside of the container of the present invention corresponds to the first contact 124 or the second contact 125.

[0046] like Figure 4 As shown, the pedestal side contact portion 22 of the pedestal 20 has a centrally recessed annular platform 222, a third contact 223 is provided on the central bottom surface of the annular platform 222, and a fourth contact 224 is provided on the top surface of the annular platform 222. The third contact 223 is formed as a substantially circular planar electrode, and the fourth contact 224 is formed as a substantially circular planar electrode. The third contact 223 and the fourth contact 224 are arranged in a concentric circle shape, and the third contact 223 and the fourth contact 224 are at different heights from each other. That is, the third contact 223 is at a lower position than the fourth contact 224.

[0047] When the spray container 10 is placed on the pedestal 20, the third contact 223 is opposite to the top surface of the circular platform 122, so that the first contact 124 and the third contact 223 are in contact (conductivity is achieved). Similarly, when the spray container 10 is placed on the pedestal 20, the fourth contact 224 is opposite to the annular flat surface 123, so that the second contact 125 and the fourth contact 224 are in contact (conductivity is achieved).

[0048] In the contact structure of the spray container 10 and the pedestal 20 according to the second embodiment, the circular pedestal portion 122 and the annular flat surface portion 123 are arranged concentrically, and the third contact point 223 and the fourth contact point 224 are planar electrodes arranged concentrically. Therefore, no matter in which direction the spray container 10 is rotated on the pedestal 20, contact can be obtained between the container-side contact portion 12 and the pedestal-side contact portion 22.

[0049] However, the first to fourth contacts 124, 125, 223, 224 are usually plated to prevent wear and corrosion of the contacts. Then, if the spray container 10 is rotated in a state arranged on the pedestal 20, the contacts rub against each other and the plating is easily removed. In the silver ion water generating spray device 1 of the second embodiment, as described above, the notch 121 formed on the container side contact portion 12 and the protrusion 221 formed on the pedestal side contact portion 22 are engaged with each other, so that the spray container 10 can be prevented from rotating on the pedestal 20 and the plating of the contacts can be prevented from falling off.

[0050] In addition, Figure 3 In the example shown, the number of the gaps 121 is 12. Figure 4 In the example shown, the number of protrusions 221 is 4. Thus, the number of notches 121 and the number of protrusions 221 do not need to be the same, as long as (the number of protrusions 221) ≤ (the number of notches 121).

[0051] In addition, the notches 121 are formed at equal angular intervals along the outer periphery of the container-side contact portion 12. On the other hand, among the protrusions 221, although it is preferred that the number of the protrusions 221 is set to a multiple of the number of the notches 121 and arranged at equal angular intervals, the protrusions 221 may not necessarily be arranged at equal angular intervals. However, if the angular interval between two adjacent notches 121 is set to α (in Figure 4 In the example of FIG. 2 , when the angle is 30° (=360° / 12), the angular interval β between two adjacent protrusions 221 is set to an integral multiple of the angular interval α.

[0052] In this way, when the rotation of the spray container 10 on the stand 20 is prevented by the engagement of the notch 121 and the protrusion 221, when the number of the notches 121 is set to n, the orientation of the spray container 10 placed on the stand 20 becomes freely rotatable at an angle interval of 360° / n. As a result, when the user places the spray container 10 on the stand 20, it is not necessary to adjust the orientation of the spray container 10 to a specific direction, thereby improving convenience.

[0053] In the pedestal side contact portion 22, the third contact 223 and the fourth contact 224 have different heights from each other, and a height difference is generated between them. Through this height difference, when a water drop (especially a water drop of silver ion water) falls on the pedestal side contact portion 22, a short circuit between the contacts can be prevented. That is, when the third contact 223 and the fourth contact 224 do not form a height difference on the same plane, the water drop that falls on the pedestal side contact portion 22 contacts both the third contact 223 and the fourth contact 224, and there is a hidden danger of a short circuit between the contacts due to the water drop. In this regard, in the case where there is a height difference between the third contact 223 and the fourth contact 224, even if a water drop falls on the pedestal side contact portion 22, the water drop can be blocked by the height difference to prevent a short circuit between the contacts caused by the water drop.

[0054] Furthermore, by making the third contact 223 and the fourth contact 224 at different heights, even if the user's finger or the like accidentally touches the pedestal-side contact portion 22, the user will not touch both the third contact 223 and the fourth contact 224 at the same time, thereby preventing electric shock.

[0055] Furthermore, in the pedestal side contact portion 22, it is preferred that a dewatering hole 225 is provided on the central bottom surface of the annular pedestal portion 222 where the third contact 223 is provided (see Figure 4 (a) and Figure 5The dehydration hole 225 can prevent water from accumulating on the central bottom surface of the annular platform 222 by releasing the water on the platform side contact portion 22 to the bottom of the platform 20. For example, it is preferably formed as a through hole to penetrate from the central bottom surface (depression) of the annular platform 222 to the bottom surface of the platform 20. Of course, the dehydration hole 225 is a component that dehydrates through a passage that does not affect the circuit substrate in the platform 20.

[0056] In the contact point structure described in the second embodiment, when the spray container 10 is placed on the stand 20 and the container-side contact point portion 12 and the stand-side contact point portion 22 are engaged, the first contact point 124 and the third contact point 223 are in contact and conduction, and the second contact point 125 and the fourth contact point 224 are in contact and conduction. Then, it is preferable that the contact points do not contact each other until the container-side contact point portion 12 and the stand-side contact point portion 22 are completely engaged. That is, it is preferable that the contact points come into contact only when the spray container 10 is completely placed on the stand 20.

[0057] Figure 6 1 is a cross-sectional view of a state before the container-side contact portion 12 and the base-side contact portion 22 are completely engaged when the spray container 10 is placed on the base 20. In this state, although the spray container 10 contacts the base 20 at points A and B in the figure, the spring contact as the first contact point 124 does not contact the third contact point 223. In addition, although Figure 6 Although not shown, at this time, the spring contact as the second contact 125 also does not contact the fourth contact 224. According to this structure, for example, when the spray container 10 is placed on the stand 20 in an empty state and the spray container 10 is not completely placed on the stand 20 but becomes a slightly floating state, incomplete conduction between the contacts can be prevented.

[0058] Furthermore, a proximity sensor (not shown) may be provided on the pedestal 20 to detect whether the spray container 10 is completely placed on the pedestal 20. That is, even if the spray container 10 is not completely placed on the pedestal 20 and floats, this state may be detected by the proximity sensor.

[0059] In the above description, a structure is exemplified in which the notch 121 of the container-side contact portion 12 and the protrusion 221 of the base-side contact portion 22 prevent the spray container 10 from rotating on the base 20. However, the present invention is not limited to this. Figure 7As shown in the figure, the following structure may be adopted: at least two notches 126 are provided on the outer periphery of the bottom of the spray container 10, and at least two protrusions 226 are provided on the upper surface of the base 20, and the rotation of the spray container 10 is prevented by the notches 126 and the protrusions 226. That is, by making the protrusions 226 provided on the base 20 face the notches 126 provided on the spray container 10, the protrusions 226 sandwich the bottom of the spray container 10, and the rotation of the spray container 10 can be prevented.

[0060] In addition, Figure 7 In the illustrated configuration, the number of notches 126 is two, and in this case, the spray container 10 can be placed on the stand 20 in two orientations that are 180° different from each other. However, the number of notches 126 is not limited to two, and if the number of notches 126 is increased, the orientations in which the spray container 10 is placed can be increased. For example, if four notches 126 are provided at equal intervals on the outer circumference of the bottom of the spray container 10, the spray container 10 can be arranged on the stand 20 in four orientations at intervals of 90°.

[0061] (Example 3: Electrode structure inside the spray container)

[0062] In the present third embodiment, the electrode structure inside the injection container 10 is described. Figure 8 It is a longitudinal sectional view which shows the structure inside the spray container 10.

[0063] like Figure 8 As described above, the spray container 10 has, as external parts constituting its appearance, a nozzle portion (cap, spray portion) 30, a connection cover portion 31, a shoulder cover portion 32, a body cover portion 33, and a bottom cover portion 34. Furthermore, the spray container 10 has an electrode holding stand 35 and a tube 36 as internal parts.

[0064] In the spray container 10, the appearance of a tank (storage portion) T for storing water is formed by the shoulder cover portion 32, the body cover portion 33, and the bottom cover portion 34, and a silver electrode portion 351 provided on an electrode holding stand 35 is arranged at the bottom of the tank T. The water stored in the tank T can elute silver ions from the silver electrode portion 351 to generate silver ion water, and the generated silver ion water can be sucked up by the tube 36 and sprayed from the nozzle 11 of the nozzle portion 30. The tank T is a member having an opening and storing liquid such as water injected from the opening.

[0065] like Figure 8 As shown in FIG. 1 , the electrode holder 35 is mounted and fixed to the upper side of the bottom cover 34 by screws or the like. The silver electrode 351 in the spray container 10 is provided on the electrode holder 35. The details will be described later, but by providing the electrode holder 35 as a component different from the bottom cover 34, the assembly of the electrical connection between the silver electrode 351 and the first contact 124 and the second contact 125 becomes easy.

[0066] Fig. 9 The figures show the electrode holding platform 35, (a) is a top view of the electrode holding platform 35, (b) is a stereoscopic view of the electrode holding platform 35 viewed from obliquely above, and (c) is a schematic top view showing the configuration of the electrode plate 353 in the electrode holding platform 35.

[0067] like Fig. 9 As shown, the electrode holding platform 35 is composed of a flange portion 352 and a silver electrode portion 351. The flange portion 352 is used to be placed on the bottom cover portion 34, and the silver electrode portion 351 is arranged on the upper side of the flange portion 352. The flange portion 352 is provided with a plurality of ( Fig. 9 The plurality of screw holes are used to fasten the electrode holding platform 35 to the bottom cover portion 34. The silver electrode portion 351 has a pair of electrode plates 353 and a pair of electrode plate supports (electrode protection portions) 354 that support each electrode plate 353 from the outside. The electrode plate support 354 is a component that abuts against the electrode plate 353 and protects the electrode plate 353. The electrode plate support 354 is equivalent to the protection portion of the present invention. The electrode plate 353 has a pair of opposing faces of the electrode plates 353 and an outer side surface inside the opposing faces, and the electrode plate support 354 covers the outer side surface of the electrode plate 353. The electrode plate support 354 can also be arranged to cover the outer side surface of the entire electrode plate 353. The electrode plate support 354 can also be arranged to protrude from the outside of the edge of the electrode plate 353 to protect the edge of the electrode plate 353. Since the electrode plate support 354 abuts against the electrode plate 353 and supports the electrode plate 353, the protection of the electrode plate 353 can be made reliable. Furthermore, since the electrode plate support 354 is a structure that is supported by contacting with the electrode plate 353, the installation accuracy of the electrode plate 353 can be highly accurate. Furthermore, since the outer side surface of the electrode plate 353 is covered by contacting with the electrode plate support 354, the corrosion of the outer side surface of the electrode plate 353 can be suppressed. Furthermore, since the opposite surface of the electrode plate 353 is not covered by the electrode plate support 354, the opposite surface of the electrode plate 353 can be easily cleaned. In addition, the opposite surface of the electrode plate 353 can be cleaned using a brush or the like. Furthermore, since the opposite surface of the electrode plate 353 is not covered by the electrode plate support 354, the visibility of the opposite surface of the electrode plate 353 is improved, and it is easy to confirm whether the electrode part needs to be cleaned. Furthermore, the silver electrode part 351 may also have an electrode plate holder 355 that holds the end of one side of the electrode plate 353 from the outside. The electrode plate 353 is held by the electrode plate holder 355, for example, by providing a holding groove in the electrode plate holder 355, and inserting the end of the electrode plate 353 into the holding groove. The electrode plate support 354 and the electrode plate holder 355 may also be connected to each other and integrally formed. In addition, the electrode plate 353 may be formed of a single silver, or may be formed of a material containing silver.

[0068] like Figure 8 As shown, the electrode plate 353 has a roughly rectangular plate-shaped portion (flat plate portion) 353a and a foot 353b extending downward from one end of the plate-shaped portion 353a, and is formed into a roughly L-shaped shape by the plate-shaped portion 353a and the foot 353b. In the electrode plate 353, for example, the rod-shaped foot 353b can also be installed on the plate-shaped portion 353a by welding, but it is preferred that the plate-shaped portion 353a and the foot 353b are formed integrally with silver as a material. In this case, the electrode plate 353 (the foot 353b also becomes a flat plate) can be easily formed by stamping from a flat silver plate. In a pair of electrode plates 353, one of them is connected to the first contact 124 provided on the bottom cover portion 34 via the foot 353b, and the other is connected to the second contact 125 provided on the bottom cover portion 34 via the foot 353b. The electrode plate 353 formed in a plate shape is, for example, formed in a thin plate shape with a thickness of 0.5 to 1.5 mm. By forming the electrode plate 353 in a thin plate shape, material costs can be reduced. Furthermore, by forming the electrode plate 353 in a thin plate shape, the processing of the electrode plate 353 becomes easier. The gap between a pair of electrode plates 353 is, for example, 3 to 13 mm. In this way, by narrowing the gap between the electrode plates 353, it becomes difficult for foreign matter to invade between the pair of electrode plates 353. Therefore, the hidden danger of damage to the electrode plate 353 is reduced.

[0069] The plate-shaped portion 353a is preferably configured to have an elongated shape (horizontally long shape) with the direction parallel to the tank bottom surface (bottom surface of the storage portion) 356 being the long side direction, so that its plane intersects (more preferably is orthogonal to) the tank bottom surface 356. By setting the plate-shaped portion 353a to a horizontally long shape, it is possible to expand the surface area while suppressing the height in the tank T. In the plate-shaped portion 353a, by expanding its surface area, silver ion water can be efficiently generated in a short time. In addition, by suppressing the height of the plate-shaped portion 353a, even when the water level in the tank T is low, the plate-shaped portion 353a becomes difficult to float to the surface, which can suppress the reduction in the efficiency of silver ion water generation.

[0070] In the electrode plate 353, one end portion (a portion of the plate-shaped portion 353a and the leg portion 353b) is protruded above the electrode holding platform 35 (i.e., inside the tank T), and the other end portion (a portion of the leg portion 353b) is protruded below the electrode holding platform 35 (i.e., outside the tank T), so as to receive power from the outside of the tank T via the leg portion 353b. A pair of electrode plates 353 is provided inside the tank T and has a plate-shaped portion 353a and a leg portion 353b, wherein the plate-shaped portion 353a is formed in a plate shape, and the leg portion 353b is fixed to the tank T protruding from a portion of the side of the plate-shaped portion 353a to the outside of the tank T. In addition, the leg portion 353b is preferably connected to the first contact 124 and the second contact 125 by means of a wire or soldering. Alternatively, the leg portion 353b may be connected to the first contact 124 and the second contact 125 by means of a mechanical method such as crimping. In addition, it is preferable to use a sealing portion (resin material) B (see Fig.13 The sealing of the sealing portion B can improve the waterproofness (sealing property) of the electrode holding platform 35, and further, can suppress (prevent loss from the base end side) the electrolysis of the foot portion 353b which is the base end portion of the electrode plate 353. The sealing portion B is equivalent to the protective portion of the present invention.

[0071] In order to obtain more reliable waterproofness (sealing), it is preferred that the sealing portion B is sealed in a manner that surrounds the entire periphery of the leg portion 353b. Therefore, in the electrode plate 353, the leg portion 353b is not formed to be aligned with one end of the plate-shaped portion 353a, but is preferably formed to be slightly offset from one end of the plate-shaped portion 353a. Fig.13 As shown in (a), even when the silver electrode portion 351 has the electrode plate holder 355, a gap can be provided between the leg portion 353b and the electrode plate holder 355, and the sealing portion B can surround the entire leg portion 353b. Fig.13 As shown in (b), the following structure may be adopted, that is, the foot portion 353b is formed to be aligned with one end of the plate-shaped portion 353a, and a height difference is provided on the holding surface of the electrode plate 353 of the electrode plate holder 355. According to this structure, a gap can be provided between the foot portion 353b and the electrode plate holder 355, and the sealing portion B can surround the entire periphery of the foot portion 353b.

[0072] In addition, the sealing portion B is preferably made of a resin material with high elasticity. The sealing portion B is formed of a material softer than the leg portion 353b and the tank T, thereby reducing the risk of damaging the leg portion 353b and the tank T. When an impact caused by an external force is applied to the electrode plate 353 in the tank T, the impact can be absorbed by the sealing portion B.

[0073] The electrode plate 353 formed in a substantially L-shape can arrange the plate-shaped portion 353a away from (in a floating manner) the electrode holding platform 35 by fixing the leg portion 353b to the electrode holding platform 35 (tank bottom surface 356) (by connecting to the first contact point 124 and the second contact point 125 via the leg portion 353b). That is, in the silver electrode portion 351, a gap is provided between the plate-shaped portion 353a and the electrode holding platform 35. By providing a gap between the tank bottom surface 356 of the tank T and the lower part of the plate-shaped portion 353a, it is possible to suppress the accumulation of liquid or the like between the pair of electrode plates 353.

[0074] When ions are generated by the silver electrode portion 351, a portion of the silver ions eluted by electrolysis between the electrode plates 353 becomes particles (silver particles). If there is no gap between the plate-shaped portion 353a and the electrode holding platform 35, the generated silver particles may accumulate between the electrodes and cause a short circuit between the electrodes. In addition, even if the electrodes are not short-circuited, there will be problems such as the silver ion elution efficiency being reduced due to the silver particles accumulated between the electrodes, and the time required to generate silver ion water of a specified concentration being prolonged.

[0075] In contrast, in the silver electrode portion 351 according to the third embodiment, since a gap is provided between the plate-shaped portion 353a and the electrode holding platform 35, the silver particles generated by electrolysis are precipitated in the space below the plate-shaped portion 353a, thereby preventing the silver particles from accumulating between the electrodes. This prevents short circuits between the electrodes and reductions in the elution efficiency of silver ions caused by the accumulated silver particles.

[0076] Further, in the spray container 10 involved in the present embodiment 3, as Figure 8 As shown in FIG. 1 , the lower end (the suction side) of the tube 36 that sucks up the silver ion water during spraying is arranged to be located below the lower end of the plate-shaped portion 353a. Thus, when the silver ion water is sprayed, the silver particles that have settled in the space that becomes the gap under the plate-shaped portion 353a can be efficiently sucked up through the tube 36. Thus, the accumulation of silver particles can be suppressed in the entire tank T, and the short circuit between electrodes and the reduction in the elution efficiency of silver ions caused by the accumulated silver particles can be further reliably avoided.

[0077] In order to properly generate silver ions in the silver electrode portion 351, it is necessary to properly maintain the inter-electrode distance of a pair of electrode plates 353. That is, by properly maintaining the inter-electrode distance, silver ion water can be generated at a specified elution rate during electrolysis. For example, when the inter-electrode distance is too wide, the elution rate of silver ions becomes low, and the generation efficiency of silver ion water decreases. On the other hand, when the inter-electrode distance is too narrow, the elution rate of silver ions becomes too high, making it difficult to adjust the concentration of silver ion water.

[0078] In addition, if Fig. 9As shown, a pair of electrode plates 353 are preferably tilted (one electrode plate 353 is configured to have an inclination angle γ (for example, 0.64°) relative to the other electrode plate 353) to form an eight-shaped shape so that the base end side (terminal side) is wide and the front end side is narrowed when viewed from above. In this tilted configuration, the electrode plate 353 is easily formed into a roughly L-shape by the plate-shaped portion 353a and the foot 353b extending downward from one end of the plate-shaped portion 353a. In this way, by making the front end side of a pair of electrode plates 353 narrower than the base end side, the electrode becomes easier to reduce on the front end side of the electrode plate 353 during electrolysis, which can prevent the electrode from being consumed from the base end side (terminal side), and can efficiently use the electrode plate 353 to the end. Furthermore, by configuring a pair of electrode plates 353 in an eight-shape, it is possible to easily pull out the electrode plate support 354 molded by resin from the mold, and visibility from above the electrode plate 353 is improved (wear of the electrode plate 353 can be easily confirmed from above).

[0079] It is difficult to properly maintain the inter-electrode distance of a pair of electrode plates 353 as described above with a single electrode plate 353. In addition, although it is conceivable to use tap water in the spray container 10, when electrolysis is performed using tap water, impurities (scale) will adhere to the surface of the electrode plate 353. In order to remove such impurities, if the surface of the electrode plate 353 is cleaned with a brush or the like, the inter-electrode distance will also change due to the brush pressure.

[0080] In this regard, since the electrode holding platform 35 involved in the present embodiment 3 is configured to support each electrode plate 353 from the outside through the electrode plate support body 354, it is easy to appropriately maintain the distance between electrodes by configuring the electrode plate 353 to contact the inner side of the electrode plate support body 354. In addition, since the electrode plate support body 354 is arranged on the outside of the electrode plate 353, when the tank T (for example, the body cover 33) of the spray container 10 is transparent, the loss of the electrode plate 353 can be hidden, and the aesthetics of the spray container 10 can be improved. In addition, the area of ​​the electrode plate support body 354 can also be made slightly larger than the electrode plate 353, and the outer peripheral edge of the electrode plate support body 354 protrudes from the outside more than the outer peripheral edge of the electrode plate 353. As a result, for example, it is possible to prevent the tube 36 from contacting the outer peripheral edge of the electrode plate 353 from the outside, and the electrode plate 353 can be reliably protected.

[0081] The electrode plate support 354 is the same as the electrode plate 353, and is a component held by the electrode holding platform 35 at the base end side, and a gap is provided between the lower end of the electrode plate support 354 and the upper surface (tank bottom surface 356) of the electrode holding platform 35. Thus, the presence of the electrode plate support 354 can prevent the accumulation of silver particles between the electrodes of the electrode plate 353. In addition, in order to improve the support strength of the electrode plate support 354, a support 354a connecting the electrode plate support 354 and the upper surface of the electrode holding platform 35 can also be provided at a position other than the base end of the electrode plate support 354. The support 354a is preferably formed into a thin columnar shape to suppress the accumulation of silver particles in the support 354a portion as much as possible.

[0082] In the above description, it is discussed that the lower end (the suction side) of the tube 36 that sucks up the silver ion water during spraying is located at a position lower than the lower end of the plate-shaped portion 353a, but it is preferred that the lower end of the tube 36 is located on the outside of the tank T, and more preferably located on the front end side of the pair of electrode plates 353 (the opposite side of the foot 353b). By configuring the tube 36 in this way, the lower end of the tube 36 can be firmly located at a position lower than the plate-shaped portion 353a, making it easy to suck up the silver particles generated after electrolysis. The thickness of the tube 36 is preferably greater than the distance between the electrodes of the electrode plates 353. By forming the diameter of the tube 36 to be larger than the gap between the pair of electrode plates 353, the tube 36 can be prevented from entering between the electrodes and contacting the electrode plates 353 (the electrode plates 353 can be protected). Furthermore, by forming the diameter of the tube 36 to be larger than the gap between the pair of electrode plate supports 354, the protection of the electrode plates 353 can be made reliable. The spray container 10 may have, for example, the following configuration in order to reliably arrange the tube 36 as described above.

[0083] As a first configuration example, it is considered that a member for guiding the tube 36 outward is provided on the member (e.g., the shoulder cover 32) that joins the nozzle portion 30 and the tank T so that the tube 36 is located on the outer side of the tank T. Specifically, Fig.10 As shown, a guide hook 321 is provided on the inner side of the shoulder cover portion 32 , and the tube 36 can be hooked by the guide hook 321 , and the tube 36 can be guided to the outer side of the tank T by the guide hook 321 .

[0084] As a second configuration example, it is considered that in the tank bottom surface 356 of the spray container 10, the height of the outer peripheral portion is made lower than the central portion (for example, a groove portion is provided along the outer periphery of the tank bottom surface 356), and the length of the tube 36 is set so that the lower end of the tube 36 is located below the center of the tank bottom surface 356. In this case, even if the lower end of the tube 36 comes to the vicinity of the central portion of the tank bottom surface 356, it can be automatically moved to the outside by the elastic force of the tube 36.

[0085] As a third configuration example, it is considered that a method is provided in the tank bottom surface 356 of the spray container 10 so that the lower end of the tube 36 stops at an appropriate position. Fig.11 As shown, a positioning plate 331 is provided on the inner side of the body cover 33. When the nozzle portion 30 is installed (screwed into) the tank T, the lower end of the tube 36 is brought into contact with the positioning plate 331 and can be positioned at an appropriate position (for example, the front end side of the electrode plate 353).

[0086] (Example 4: Display Light)

[0087] In the silver ion water generating and ejecting device 1 according to the fourth embodiment, for example, during electrolysis, the display lamp (display unit) of the stand 20 is lit so as to notify the user of information on the electrolysis process.

[0088] Fig.12 1 is a diagram showing a configuration example of the pedestal 20 according to the fourth embodiment, wherein (a) is an exploded perspective view of the pedestal 20, and (b) is a perspective view of the indicator light 20 included in the pedestal 20 when viewed from obliquely below. Fig.12 As shown, in the pedestal 20, an annular light guide 24 and a plurality of light emitting elements 25 (eg, LEDs) are provided inside the pedestal housing 23 (upper housing 231 and lower housing 232). Fig.12 In the pedestal 20 shown, the annular light guide 24 and the light emitting element 25 function as indicator lights.

[0089] In the annular light guide 24, Fig.12 As shown in (b), the top is set to be flat, and a plurality of ( Fig.12 These multiple inclined protrusions 241 are formed in the same inclined direction along the circumferential direction of the annular light guide 24, and a step 242 that becomes a vertical surface is formed at the end of one side of the inclined protrusion 241 (the end on the side where the thickness of the annular light guide 24 increases due to the inclined protrusion 241).

[0090] The light-emitting element 25 is arranged below the annular light guide 24 in such a manner that its light-emitting surface is opposite to the vertical surface of the step 242. The irradiated light from the light-emitting element 25 is incident on the annular light guide 24 from the step 242 in the horizontal direction, and is further reflected upward at the inclined surface (below) of the inclined protrusion 241. Thus, with a smaller number of light-emitting elements 25, the annular light guide 24 can be made to emit light in a circular shape as uniformly as possible. In addition, even if water reaches the annular light guide 24, it can be imagined that the water reaches the inclined protrusion 241 and falls to the lower part, so by keeping the light-emitting element 25 at a certain distance from the step 242, it is possible to avoid water leakage directly to the light-emitting element 25.

[0091] The upper surface of the annular light guide 24 is exposed on the upper surface of the pedestal 20, and its upper surface is covered by a waterproof seal 26. The waterproof seal 26 covers the entire upper surface of the pedestal 20 except for the pedestal-side contact portion 22, and covers not only the annular light guide 24 but also the operation button 21. Thus, the waterproof seal 26 prevents water from intruding into the interior of the pedestal 20.

[0092] The inner diameter of the annular light guide 24 is set to be larger than the outer diameter of the bottom of the spray container 10. In addition, the operation button 21 is arranged on the outer peripheral side of the annular light guide 24. When the spray container 10 is arranged on the pedestal 20, the annular light guide 24 is arranged on the outer peripheral side of the spray container 10, forming a periphery surrounding the spray container 10. As a result, the user can also recognize the lighting of the display light (light emission of the annular light guide 24) from any of the four directions. In addition, by bringing the annular light guide 24 close to the spray container 10, the irradiated light of the annular light guide 24 can be reflected by the side of the spray container 10. In this case, the lighting of the display light can be easily recognized even from the horizontal direction. In addition, when the tank T of the spray container 10 is transparent, the bubbles generated during electrolysis can be made obvious by light, and the user can also easily recognize the state of electrolysis.

[0093] A plurality of light emitting elements 25 are mounted on a common circuit board 27 and are controlled to emit light. Then, by controlling the light emission of each light emitting element 25 to change the light emission timing, it is also possible to inform the user of changes in the electrolysis state. For example, it is conceivable that changes in the light emission timing of the light emitting element 25 can convey high-concentration / low-concentration electrolysis mode, time until electrolysis is completed, electrode life, etc.

[0094] In the silver ion water generating and ejecting device 1 according to the fourth embodiment, for example, after the operation button 21 is turned on and electrolysis is started, it is considered that the operation button 21 is not input again until the electrolysis is completed. This is to prevent the operation button 21 from being turned off during electrolysis and resetting the electrolysis time. That is, by preventing the electrolysis time from being reset, the electrolysis concentration of the generated silver ion water can be fixed (a predetermined electrolysis concentration is obtained).

[0095] In this case, it is preferred to control the lighting of the indicator light to notify the user of the status during electrolysis and the completion of electrolysis. As a specific example, consider turning the indicator light on and off at a specified interval (e.g., 1 second interval) during electrolysis (e.g., 60 seconds), and turning the indicator light on when the electrolysis is completed. In addition, it is preferred to set the lighting of the indicator light indicating the completion of electrolysis to a fixed time (e.g., 1 minute). During the lighting period of the indicator light after the completion of electrolysis, by setting it to a long time, the user can be prevented from overlooking and the completion signal can be reliably conveyed.

[0096] (Example 5: Container structure inside the spray container)

[0097] In the fifth embodiment, a structural example of a tank T suitable for the spray container 10 is described. In the spray container 10, as described above, the appearance of the tank T for storing water is formed by the shoulder cover 32, the body cover 33, and the bottom cover 34. That is, the tank T of the spray container 10 is not formed integrally as one component, but is formed by combining a plurality of components. This is because the spray container 10 has the following advantages.

[0098] First, the separation structure of the body cover 33 and the bottom cover 34 is suitable for arranging the electrode holder 35 at the bottom of the tank T. That is, if the body cover 33 and the bottom cover 34 are separated, after the electrode holder 35 is mounted on the bottom cover 34, the body cover 33 is further mounted, so that the electrode holder 35 can be easily arranged at the bottom of the tank T. Figure 8 In the spray container 10 shown, a packing 40 is provided for preventing water leakage between the body cover 33 and the bottom cover 34 .

[0099] For example, the body cover 33 , the bottom cover 34 , and the electrode holding stand 35 can be assembled by the following steps.

[0100] First, the electrode plate 353 is mounted on the electrode holding platform 35. Specifically, the foot 353b of the electrode plate 353 is inserted from above into the opening formed in the electrode holding platform 35, and a resin material or the like is filled around the foot 353b of the opening, and a sealing portion B is formed between the foot 353 and the tank T.

[0101] Next, the leg 353b of the electrode plate 353 is electrically connected to the connection part 341. The connection part 341 is connected to the first contact 124, the second contact 125, and the electrode plate 353. The connection part 341 is equivalent to the protection part of the present invention. For example, the first contact 124 and the second contact 125 are installed on the connection part 341 after the electrode plate 353 is installed. In addition, the electrode plate 353 may be installed on the connection part 341 after the first contact 124 and the second contact 125 are installed. By connecting the first contact 124, the second contact 125 and the electrode plate 353 via the connection part 341, the load acting on the first contact 124, the second contact 125 or the leg 353b of the electrode plate 353 can be reduced. For example, when the spray container 10 is placed on the pedestal 20, the force acting on the first contact 124 and the second contact 125 acts on the leg 353b via the connection part 341. That is, the connection portion 341 has a function of reducing the force acting on the first contact 124, the second contact 125 or the electrode plate 353. For example, the connection portion 341 and the electrode plate 353 may be connected via a wire or the like. The wire or the like can further reduce the load acting on the first contact 124, the second contact 125 or the foot 353b. In addition, for example, the first contact 124, the second contact 125 and the foot 353b may also be arranged at different positions on a plane (horizontal plane) parallel to the tank bottom surface 356 formed at the bottom of the tank T. By arranging the first contact 124, the second contact 125 or the foot 353b at different positions, the load acting on the foot 353b can be further reduced.

[0102] The electrode holder 35 having the electrode plate 353, the connection portion 341, the first contact point 124, and the second contact point 125 mounted thereon is mounted on the body cover 33. A gasket 40 is provided between the electrode holder 35 and the body cover 33. The electrode holder 35 and the gasket 40 are fixed to the body cover 33 by the bottom cover 34 while being pressed by the body cover 33. The bottom cover 34 and the body cover 33 form the outline of the spray container 10. The electrode holder 35 is accommodated in a space surrounded by the bottom cover 34 and the body cover 33. The bottom cover 34 and the body cover 33 are fixed to the outside of the gasket 40 in the circumferential direction by screws 42 and the like. The screws 42 are inserted from the lower side of the bottom cover 34, penetrate through the screw holes provided on the electrode holder 35, and are connected to the body cover 33.

[0103] Next, the separation structure of the shoulder cover 32 and the body cover 33 is suitable for improving the cleanability of the tank T and the ease of water supply. That is, the upper part of the tank T connected to the nozzle part 30 needs to be formed into a narrow neck shape. At this time, if the shoulder cover 32 and the body cover 33 are formed as one body (inseparable), it is difficult to clean the inside of the tank T from the upper part of the narrow neck of the tank T. Since the shoulder cover 32 and the body cover 33 are separable, it is easy to clean either the shoulder cover 32 or the body cover 33 (can be cleaned from the wide opening side). In addition, when supplying water to the spray container 10, by removing the shoulder cover 32 from the body cover 33, water can be supplied from the wide opening, making water supply easy. In addition, by making the shoulder cover 32 detachable, it is also easy to replace the nozzle part 30 as a consumable.

[0104] In addition, it is preferred that no undercut is formed on the upper portion of the body cover portion 33 at the connection between the shoulder cover portion 32 and the body cover portion 33. Figure 8 As shown, the upper portion of the body cover 33 is not reduced in diameter compared to other portions (if the diameter of the upper portion is reduced, an undercut (height difference) is formed on the inner surface of the body cover 33), and an external thread is formed on the upper edge portion formed on a slightly thick wall (an internal thread is formed on the lower edge portion of the shoulder cover 32). In this way, by not forming an undercut on the body cover 33, the formability of the body cover 33 can be improved, and the cleaning of the inside of the tank T can also be facilitated.

[0105] In addition, in Figure 8 In the spray container 10 shown in FIG. 1 , a gasket 41 is provided to prevent water leakage between the shoulder cover 32 and the body cover 33. Figure 8 As shown, the pad 41 is preferably configured to contact the upper end of the body cover 33. For example, Figure 8 As shown in the example of an inappropriate method, when the pad 41 is arranged near the lower end of the shoulder cover 32, water may accumulate in the gap between the shoulder cover 32 and the body cover 33 above the pad 41. For example, the water accumulated in the gap may overflow when the shoulder cover 32 is removed from the body cover 33 on the pedestal 20, and there is a risk of soaking the pedestal 20. The pad 41 arranged to contact the upper end of the body cover 33 can prevent water from accumulating in the gap between the shoulder cover 32 and the body cover 33.

[0106] In addition, it is preferable that at least the side surface (i.e., the body cover 33) of the tank T in the spray container 10 is provided as a transparent or translucent light-transmitting portion. Thus, the visibility of the water level in the tank T can be improved. If the visibility of the water level is good, there are advantages such as: by providing a specified amount of water level scale on the side surface of the tank T, it is easy to put a fixed amount of water, and it is easy to judge whether it is before or after electrolysis by the turbidity of the water.

[0107] (Example 6: Action Control Example)

[0108] In the sixth embodiment, an operation control example suitable for the silver ion water generating and ejecting device 1 will be described.

[0109] In the silver ion water generating and spraying device 1 involved in the present embodiment 6, a current sensor and a voltage sensor for detecting the inter-electrode current and voltage of the silver electrode portion 351 may also be provided in the power supply circuit on the side of the pedestal 20, and the electrolysis current may be adjusted based on the detection results of these sensors. The hardness and water temperature of the water (usually tap water) in the tank T of the spray container 10 are not fixed. Therefore, the electrolysis rate varies due to the hardness and water temperature of the water in the tank T, and even if the electrolysis is performed in the same amount of water for the same time, the electrolysis concentration of the generated silver ion water is different. In this regard, if adjustments are made to suppress the variation of the electrolysis current based on the detection results of the sensor, it is possible to cope with the hardness and water temperature of the water in the tank T over a wide range, and stabilize the electrolysis concentration of the silver ion water.

[0110] In addition, it is also considered to compare the last electrolysis (for example, within 1 hour) and the current electrolysis, and compare the current and voltage between the electrodes based on the detection results of the sensor to determine whether the electrolysis is completed. For example, if the current of the current electrolysis is greater than the reference value compared with the last electrolysis, it can be determined that the water in the tank T has been electrolyzed, and the current electrolysis can be canceled based on this judgment.

[0111] (Example 7: Shape example of the silver electrode portion)

[0112] In the present seventh embodiment, a modification example of the silver electrode portion 351 suitable for the spray container 10 will be described.

[0113] In the third embodiment, the electrode plate 353 is composed of the plate-shaped portion 353a and the leg portion 353b, and the plate-shaped portion 353a is formed in a flat plate shape. However, in the present invention, the plate-shaped portion 353a is not limited to a flat plate shape.

[0114] Fig.14 (a) and (b) are schematic top views of the silver electrode portion 351 at the bottom of the tank T as viewed from above. Fig.14 As shown in (a) and (b), the plate-shaped portion 353a can also form a flat silver plate into a straight line or a curve in a top view (it can also be a combination of straight line bending and curve bending). Of course, when the plate-shaped portion 353a is set to a curved shape, the electrode plate support 354 is also set to a shape consistent with the plate-shaped portion 353a. Thus, by setting the plate-shaped portion 353a to a curved shape, the maximum length of the long side direction of the plate-shaped portion 353a can be suppressed while increasing the surface area of ​​the plate-shaped portion 353a. That is, the electrode plate 353 with a large surface area and high efficiency in generating silver ion water can be compactly accommodated in the tank T.

[0115] In addition, the pair of curved plate-shaped portions 353a are preferably arranged symmetrically with respect to the center point of the tank T in a plan view. In this case, the inclinations of the two ends of the pair of plate-shaped portions 353a with respect to the radial direction of the tank T are in the same direction. Thus, for example, when cleaning the tank T, when water is poured into the tank T and stirred so that a water flow is generated in the direction of the arrow R, the water flow becomes easy to enter between the electrodes from the two ends of the plate-shaped portion 353a. By allowing the water flow to enter between the electrodes in this way, the cleaning effect on impurities (scale) attached to the surface of the plate-shaped portion 353a can be improved.

[0116] The following configuration may be adopted: in order to allow water to flow into the electrode space from both ends of the plate-shaped portion 353a, a holding protrusion 357 erected upward from the tank bottom surface 356 may be provided near the center of the pair of plate-shaped portions 353a in the long side direction, instead of the electrode plate holding body 355 that holds the ends of the electrode plate 353. By providing the holding protrusion 357, each electrode plate 353 can be held in a manner that the plate-shaped portion 353a is sandwiched between the electrode plate support body 354 and the holding protrusion 357. In addition, the holding protrusion 357 has a function of preventing the electrode plate 353 from tipping inward, contacting each other, and short-circuiting.

[0117] In addition, in order to make it easier for water to flow into the electrode space from both ends of the electrode plate 353, the electrode plate 353 may be configured as follows: Fig.15 The composition shown in (a) or (b). Fig.15 In (a), the plate-shaped portion 353a is formed by curving in a curved manner, and the curvature of the two end portions is greater than the curvature of the central portion. In this case, by increasing the curvature of the two end portions of the plate-shaped portion 353a, the inclination relative to the radial direction of the tank T becomes larger, and the water flow in the direction of the arrow R easily enters between the electrodes from the two end portions of the plate-shaped portion 353a. In addition, the central portion of the plate-shaped portion 353a has a small curvature, so the flow resistance is small, and the water flow entering from the two end portions easily reaches the central portion.

[0118] Fig.15In (b), the structure is that the plate-shaped portion 353a is formed by bending in a curved manner, and at the ends of a pair of plate-shaped portions 353a, the end of one plate-shaped portion 353a is arranged on the outer side in the radial direction than the end of the other plate-shaped portion 353a, and a "receiving" structure is provided to facilitate the water flow in the direction of arrow R from the end of the plate-shaped portion 353a to enter between the electrodes. For example, by forming the end of one plate-shaped portion 353a to be inclined approximately 90 degrees in the radial direction than the other plate-shaped portion 353a, the end of the other plate-shaped portion 353a is covered, and the above-mentioned effect is further improved. In addition, for example, the end of the plate-shaped portion 353a on one side is formed to be inclined approximately 90 degrees in the radial direction than the plate-shaped portion 353a on the other side, and the curvature of the end side of the plate-shaped portion 353a on one side is formed to be smaller than the curvature of the end side of the plate-shaped portion 353a on the other side, thereby covering the end of the plate-shaped portion 353a on the other side, thereby further improving the above-mentioned effect.

[0119] In addition, the water flow in the direction of arrow R can easily enter the electrode from the end of the plate-shaped portion 353a in this "receiving" structure. Fig.16 As shown in (a) and (b), it is also possible to set it according to the shape of the electrode plate support body 354 instead of the shape of the plate-shaped portion 353a. That is, Fig.16 In (a) and (b), the structure is that at the end of a pair of electrode plate supports 354, an extension portion 354b is provided on the end of one electrode plate support 354, extending toward the outer periphery of the tank T and toward the side of the other electrode plate support 354, and a "receiving" structure is provided so that the water flow in the direction of arrow R can easily enter the electrodes from the end of the plate-shaped portion 353a. The extension portion 354b can also be formed as follows Fig.16 The straight line shown in (a) can also be formed as Fig.16 (b) is the curve shown.

[0120] In addition, Fig.14 and Fig.15 In the illustrated example, the plate-shaped portion 353 a of the electrode plate 353 is formed to be bent periodically in a left-right manner along the longitudinal direction, but the plate-shaped portion 353 a may be bent non-periodically.

[0121] For example, Fig.17 As shown in (a) and (b) of FIG. 1 , the plate-shaped portion 353a may also be a simple shape bent once. In this case, the total length of the pair of plate-shaped portions 353a may be as long as Fig.17 The length shown in (a) is different, and can also be Fig.17 The same length as shown in (b).

[0122] In addition, if Fig.18As shown, the plate-shaped portion 353a may also be configured as a spiral shape that is bent multiple times in either the left or right direction. Fig.18 In the case of the spiral shape shown, the silver electrode portion 351 can be arranged using a two-dimensional wide space in a plan view. Therefore, the electrode plate 353 having a larger surface area and high efficiency in generating silver ion water can be accommodated in the tank T in a compact manner.

[0123] like Fig.18 The plate-shaped portion 353a shown in the figure can be formed by bending a flat plate electrode plate multiple times, or by combining a plurality of flat plate electrode plates. Since a flat plate electrode plate is used in any method, the production cost of the electrode plate 353 can be reduced.

[0124] also, Fig.14 , Fig.15 , Fig.17 and Fig.18 The plate-shaped portion 353a of the electrode plate 353 shown in the figure has an elongated shape (horizontally long shape) with the direction parallel to the tank bottom surface 356 as the long side direction in the horizontal projection shape (the projection shape in which the projection length in the horizontal direction becomes the largest). That is, the plate-shaped portion 353a has a shape in which the second side intersecting the first side is shorter than the first side parallel to the tank bottom surface 356 of the tank T. Thus, similar to the plate-shaped portion 353a of the plate shape shown in the third embodiment, the height of the plate-shaped portion 353a in the tank T can be suppressed while the surface area can be expanded.

[0125] In addition, if Fig.19 As shown, a hollow portion 353c penetrating the plate-shaped portion 353a in the thickness direction may be provided on the electrode plate 353. The hollow portion 353c is provided as a notch extending along the long side direction (i.e., the horizontal direction) of the plate-shaped portion 353a, and is provided as a trapezoidal notch portion whose width increases from the end provided at the foot portion 353b toward the end on the opposite side of the foot portion 353b. In addition, the end of the hollow portion 353c on the opposite side of the foot portion 353b is open, and a circular hollow is provided at the end on the opposite side of the foot portion 353b.

[0126] By providing the hollow portion 353c on the plate-shaped portion 353a, the ratio of the surface area of ​​the accumulation relative to the plate-shaped portion 353a can be increased. Thus, high-concentration silver ion water can be easily and efficiently generated. In addition, the circular hollow provided at the end of the hollow portion 353c has the function of preventing the electrode from being damaged due to the dissolution of the electrode of the plate-shaped portion 353a, so that the electrode plate 353 can be used for a long time.

[0127] In addition, Fig.19In the embodiment, although the notch serving as the cavity 353c is provided only in the plate-shaped portion 353a, the same notch may be provided in the electrode plate support 354. When the notch is also provided in the electrode plate support 354, a cavity penetrating both the plate-shaped portion 353a and the electrode plate support 354 in the thickness direction is formed, so that water can easily pass between the electrodes when the tank T of the spray container 10 is cleaned, and the cleaning effect can be improved.

[0128] In addition, if Fig. 20 As shown in (a) and (b), a groove portion 353d that does not penetrate the plate-shaped portion 353a in the thickness direction may be provided on the surface of the plate-shaped portion 353a of the electrode plate 353. Here, the surface of the plate-shaped portion 353a is the surface on the opposite side of the contact surface with the electrode plate support 354, and the contact surface with the electrode plate support 354 is set as the inside of the plate-shaped portion 353a. By providing the groove portion 353d on the plate-shaped portion 353a, the ratio of the accumulated surface area relative to the plate-shaped portion 353a can also be increased, making it easy to efficiently generate high-concentration silver ion water.

[0129] The groove 353d is formed along the long side direction (i.e., the horizontal direction) of the plate-shaped portion 353a, and in particular, the bottom of the groove is preferably set as an inclined surface so as to descend from the inside to the surface of the plate-shaped portion 353a. By making the bottom of the groove 353d inclined, scale generated in the groove 353d can be easily dropped, and the scale can be prevented from clogging the groove 353d. In addition, the top of the groove 353d can also be inclined in the same manner as the bottom of the groove (see Fig. 20 (a)), or it can also be a horizontal plane (refer to Fig. 20 (b)).

[0130] Furthermore, the cross section of the plate-shaped portion 353a of the electrode plate 353 may also be set to be approximately trapezoidal, so that the thickness of the upper end side is thin and the thickness of the lower end side is thick. By setting the cross section of the plate-shaped portion 353a to be approximately trapezoidal, it is difficult to cause the plate-shaped portion 353a to collapse (top end side toppling) due to wear (thinning) of the electrode and a short circuit caused by the collapse, so that the electrode plate 353 can be used for a long time.

[0131] In addition, the container and container placement member of the present invention can also be described as follows. Other embodiments of the present invention relate to a metal ion water generating container (container) characterized in that it has a tank and a metal electrode portion, the tank has an opening and stores liquid, the metal electrode portion is arranged in the tank, the metal motor portion has a pair of electrode plates arranged away from each other and configured to contact the liquid stored in the tank, and the electrode plates are formed of a material containing a metal that can elute metal ions having an antibacterial effect in the liquid.

[0132] According to the above structure, a metal electrode portion is provided in the tank of the metal ion water generating container. By passing electricity between the electrodes of a pair of electrode plates containing the metal electrode portion, metal ions with antibacterial effects in the liquid (usually water) are eluted in the container, thereby generating high-concentration metal ion water in a short time.

[0133] Furthermore, in the metal ion water production container, one end portion of the electrode plate may be fixed to the can, and a periphery of the one end portion of the electrode plate and the can may be sealed with resin.

[0134] According to the above configuration, the surrounding of the fixing position of the electrode plate is sealed with resin, which can improve the waterproofness (sealing) between the electrode plate and the tank. Further, it is possible to suppress (prevent loss from the base end side) electrolysis of the base end portion (the portion connected to the terminal) of the electrode plate.

[0135] Furthermore, in the metal ion water production container, the pair of electrode plates may be integrally formed of a material containing silver.

[0136] Furthermore, in the metal ion water production container, at least a side surface of the tank may be transparent or translucent.

[0137] According to the above structure, the following advantages are achieved: the water level in the tank is well visible, and a fixed amount of water can be easily put in by setting a specified amount of water level scale on the side of the tank, or it is easy to judge whether it is before or after electrolysis by the turbidity of the water.

[0138] Furthermore, in the metal ion water production container, the metal electrode portion may be provided at a position visible from the outside via a side surface of the tank.

[0139] According to the above configuration, the wear of the electrode plate in the metal electrode portion can be confirmed from the outside.

[0140] In the metal ion water generating container, the electrode plate may include a substantially rectangular flat plate portion and a leg portion extending downward from one end of the flat plate portion, and the pair of electrode plates may be arranged to face the flat plate portions, respectively.

[0141] In the metal ion water production container, the flat plate portions of the pair of electrode plates may be arranged to be inclined such that the base end side having the terminal is wider and the front end side is narrower.

[0142] According to the above structure, by making the front end side of a pair of electrode plates narrower than the base end side, the electrode becomes easier to reduce on the front end side of the electrode plate during electrolysis, which can prevent the electrode from being consumed from the base end side (terminal side) and enable the electrode plate to be used efficiently to the end.

[0143] Furthermore, in the metal ion water production container, the flat plate portion of the electrode plate may be arranged away from the bottom of the tank.

[0144] According to the above configuration, by moving the electrode plate away from the bottom of the tank, a gap can be provided between the flat plate portion and the bottom of the tank, so that metal particles (silver particles) generated by electrolysis are precipitated in the space below the flat plate portion to form the gap, thereby preventing metal particles from accumulating between the electrodes. Thus, short circuits between the electrodes caused by accumulated metal particles and reduced elution efficiency of metal ions can be avoided.

[0145] Furthermore, in the metal ion water production container, the pair of electrode plates may be respectively supported from outside by a support body.

[0146] According to the above configuration, each electrode plate is supported from the outside by the support body, so that the distance between electrodes can be easily maintained appropriately.

[0147] Furthermore, the metal ion water production container may include a spray unit configured to spray the liquid stored in the tank.

[0148] In addition, in the metal ion water generating container, the electrode plate can be constructed to have a roughly rectangular flat plate portion and a foot portion extending downward from one end of the flat plate portion, and the electrode plate is arranged away from the tank, and the lower end of the tube that sucks up the liquid stored in the tank and sends it into the injection portion is located below the lower end of the flat plate portion.

[0149] According to the above structure, when the metal ion water is sprayed, the metal particles that have settled in the space below the flat plate can be efficiently sucked up by the tube, and the accumulation of metal particles in the entire tank can be suppressed. Thus, the short circuit between electrodes caused by the accumulated metal particles and the reduction of the elution efficiency of metal ions can be more reliably avoided.

[0150] In addition, another aspect of the metal ion water generating device (container placement device) of the present invention is characterized in that it is composed of the metal ion water generating container described above and a base for placing the metal ion water generating container, and the base is also provided with a power supply unit, and when the metal ion water generating container is placed on the base, the power supply unit can supply power to the metal electrode part of the metal ion water generating container.

[0151] According to the above configuration, by providing the power supply unit on the stand, it is possible to reduce the weight of the metal ion water generating container and improve the safety of the user when spraying the metal ion water (preventing electric shock).

[0152] In addition, the metal ion water generating device is constructed such that power is supplied from the pedestal to the metal ion water generating container by contact power supply, the metal ion water generating container has a container side contact portion formed in a concave shape on the bottom surface, and the pedestal has a pedestal side contact portion formed in a convex shape on the top surface. When the metal ion water generating container is placed on the pedestal, the metal ion water generating container can be positioned on the pedestal by engaging the container side contact portion and the pedestal side contact portion.

[0153] According to the above configuration, by positioning the metal ion water production container on the stand, the contact point between the container side contact point portion and the stand side contact point portion can be stabilized (power supply can be performed reliably).

[0154] Furthermore, in the metal ion water generating device, the container-side contact portion and the base-side contact portion may be configured to prevent the metal ion water generating container from rotating on the base when the container-side contact portion and the base-side contact portion are engaged with each other.

[0155] According to the above configuration, the metal ion water generating container can be prevented from rotating on the stand, and the plating layer can be prevented from coming off due to friction at the contact point.

[0156] In addition, in the metal ion water generating device, it can be configured that the metal ion water generating container has an injection portion for injecting the liquid stored in the tank, and when the metal ion water generating container is placed on the base, the front end of the nozzle of the injection portion is located at a position further outside than the outer periphery of the base when viewed from above.

[0157] According to the above configuration, even if the metal ion water adhering to the front end of the shower head drops, it is possible to prevent the dropped metal ion water from splashing onto the pedestal.

[0158] Furthermore, in the metal ion water generating device, the pedestal may include a dewatering hole for draining water on the pedestal-side contact portion toward a lower portion of the pedestal.

[0159] According to the above configuration, it is possible to prevent water from being accumulated on the pedestal-side contact portion.

[0160] Furthermore, in the metal ion water producing device, the stand may include an indicator light, and when the metal ion water producing container is placed on the stand, the indicator light may be arranged on the outer peripheral side of the metal ion water producing container.

[0161] According to the above configuration, the user can be informed of the electrolysis state of the metal ion water generating device and the like by controlling the light emission of the indicator lamp.

[0162] Furthermore, in the metal ion water generating device, the indicator lamp may be arranged to surround the metal ion water generating container.

[0163] According to the above configuration, the user can recognize the lighting of the indicator light from any of the four directions.

[0164] Furthermore, in the metal ion water generating device, an operation button operated when starting electrolysis in the metal ion water generating device may be provided on the pedestal, and the operation button may be arranged on the outer peripheral side of the indicator lamp.

[0165] In addition, in order to solve the above-mentioned problems, the third type of the injection device of the present invention is characterized in that it comprises: a tank that stores liquid; an electrode that protrudes into the interior of the tank and is formed of a silver-containing material; and a injection part that injects silver ion water generated by the electrode.

[0166] In addition, the container of the present invention comprises: a storage part having an opening and storing liquid; a pair of electrode plates having a plate-shaped part and a leg, the plate-shaped part being arranged inside the storage part and formed into a plate shape, the leg protruding from a part of the edge of the plate-shaped part to the outside of the storage part and being fixed to the storage part; and a protection part protecting the electrode plate. The protection part is a component for protecting the electrode plate, and in the above-mentioned embodiment, it comprises a sealing part, an electrode protection part or a connecting part. In addition, for example, when a finger, a long and thin tool in the shape of a rod directly contacts the electrode plate, or when an impact is transmitted to the electrode plate when the container is placed on a pedestal, the protection part reduces the hidden danger of damage to the electrode plate. For example, a gap is provided between the bottom surface of the storage part and the lower part of the plate-shaped part. For example, a cover covering the opening and a tube mounted on the cover and through which the liquid flows are provided, and the diameter of the tube is formed to be larger than the gap between the pair of electrode plates. For example, a contact exposed to the outside of the container is provided, and the protection part includes a connecting part connecting the contact and the leg. For example, the contact and the leg are provided at different positions on a surface parallel to the bottom surface of the storage part. For example, the protection portion includes an electrode protection portion covering the outer surface of a pair of electrode plates. For example, the protection portion includes a sealing portion, the sealing portion is between the periphery of the foot portion and the storage portion, and is formed of a material softer than the storage portion.
