Detailed Description

(example 1 basic Structure of silver ion Water generating Ejection apparatus)

Fig. 1 is an exploded perspective view showing an external appearance of a silver ionized water generating and spraying apparatus (container module, metal ionized water generating apparatus) 1 according to an embodiment of the present invention. In embodiment 1, a basic configuration of the silver ionized water generating and ejecting apparatus 1 will be described. As shown in fig. 1, the silver ion water generating/ejecting apparatus 1 includes an ejecting container (container, metal ion water generating container) 10 and a pedestal (holder) 20 on which the ejecting container 10 is placed. The spray container 10 is a container having a head 11, and the silver ionized water generated and stored in the container can be sprayed from the head 11. Although silver ions are exemplified as the metal ions to be generated, the metal ions are not particularly limited if they can generate a certain metal ion having an antibacterial action, and copper, zinc, or the like may be used in addition to silver.

The ejection container 10 has a silver electrode portion (electrode portion) 351 (see fig. 8) at a position that comes into contact with (is soaked in) water when the water is stored in the container. When the ejection container 10 is placed on the base 20, the silver electrode unit 351 of the ejection container 10 can be supplied with power from the power supply unit provided in the base 20. That is, the ejection container 10 is placed on the base 20, the silver electrode unit 351 is energized, and when the electrode is energized, silver ions are eluted from the silver electrode unit 351 into water, and silver ion water is generated in the ejection container 10. When the silver ionized water is generated in the spray container 10, the user can spray the silver ionized water from the spray container 10 only by picking up the spray container 10. In the silver ionized water producing and ejecting apparatus 1 shown in fig. 1, the operation button (operation portion) 21 provided on the base 20 is pressed in a state where the ejection container 10 is placed on the base 20, and thereby the power supply to the silver electrode portion 351 can be started (the generation of the silver ionized water is started).

In the silver ionized water producing and ejecting apparatus 1 according to example 1, since silver ions can be produced by applying current between the electrodes of the silver electrode unit 351, high-concentration silver ionized water can be easily produced in a short time.

Further, the ejection container 10 itself does not include a power supply portion, but includes a power supply portion on the base 20. This can reduce the weight of the spray container 10, and improve safety (prevention of electric shock) when the user sprays the silver ionized water. In addition, when the spray container 10 is submerged in water by mistake during use, the power supply circuit is not damaged. Further, the head 11 and the silver electrode portion 351, which are consumed in the ejection container 10 due to daily use, may be replaced integrally for use.

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, and the external power source (commercial power source) is more preferably used. When an external power supply is used as the power supply of the pedestal 20, explosion or the like due to short-circuiting of the battery due to water leakage or the like can be avoided. In addition, since the power supply voltage can be made constant by using the external power supply, it is possible to avoid an erroneous operation due to a voltage variation.

For the power supply to the ejection container 10 from the pedestal 20, either a contact power supply method or a 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 the daily use of the silver ion water generating/ejecting apparatus 1, a large amount of water is not splashed on the outside of the pedestal 20 and the ejection container 10, and the necessity of using the contactless power supply system having high water resistance is low.

However, since it is assumed that a small amount of water falls from the spray container 10 and splashes on the pedestal 20, it is preferable to take measures against this, particularly in the case of using the contact power supply system. For example, when the spray container 10 is placed on the base 20, as shown in fig. 2, the tip of the head 11 is preferably located outside the outer periphery of the base 20 when viewed from above. At this time, the tip of the head 11 is positioned outside the outer periphery of the base 20 regardless of the orientation of the spray container 10 on the base 20. Thus, even if the silver ion water attached to the tip of the head 11 drops, the dropped silver ion water can be prevented from splashing on the pedestal 20.

(embodiment 2: contact Structure of spray Container and pedestal)

In example 2, a description will be given of a contact structure between the spray container 10 and the pedestal 20 of the silver ionized water producing spray apparatus 1. Here, it is assumed that a contact power feeding method is used for feeding power from the pedestal 20 to the ejection container 10.

Fig. 3 is a view showing the container-side contact portion 12 formed on the bottom surface of the spray container 10, where (a) is a bottom surface view of the spray container 10, and (b) is an enlarged perspective view of the vicinity of the bottom portion of the spray container 10 as viewed obliquely from below. Fig. 4 is a view showing a pedestal-side contact portion (holding portion) 22 formed on the upper surface of the pedestal 20, where (a) is a plan view of the pedestal 20, and (b) is a perspective view of the pedestal 20 as viewed from obliquely above.

As shown in fig. 3 and 4, container side contact portion 12 of spray container 10 is formed in a concave shape on the bottom surface of spray container 10, and base side contact portion 22 of base 20 is formed in a convex shape on the upper surface of base 20. Thus, when spray container 10 is placed on base 20, container-side contact portion 12 and base-side contact portion 22 can be fitted into the unevenness, and spray container 10 can be positioned on base 20. By positioning spray container 10 on base 20 in this manner, the contact point between container-side contact point 12 and base-side contact point 22 can be firmly contacted (power supply can be reliably performed).

A plurality of notches 121 are formed at regular angular intervals along the outer peripheral edge of the container side contact portion 12. Further, a plurality of protrusions 221 are formed along the outer peripheral edge on the base-side contact portion 22. Thus, when spray container 10 is placed on base 20, notch 121 and projection 221 are fitted to each other, thereby preventing spray container 10 from rotating on base 20. This prevents the contact points from rubbing against each other between container-side contact point 12 and base-side contact point 22.

As shown in fig. 3, the container side contact portion 12 of the spray container 10 has a circular table portion 122 having a flat top surface at the center thereof, and an annular flat surface portion 123 around the circular table portion 122 (inside the notch 121). The circular table portion 122 and the annular flat surface portion 123 are arranged concentrically, and the top surface of the circular table portion 122 and the annular flat surface portion 123 are different in height from each other. When the spray container 10 is placed on the pedestal 20, the top surface of the circular table portion 122 is positioned lower than the annular flat surface portion 123.

At least one first contact 124 (two in fig. 3) is provided on the top surface of the circular table portion 122, and at least one second contact 125 (two in fig. 3) is provided on the annular flat surface portion 123. At this time, one of the first contact 124 and the second contact 125 serves as a positive-side contact, and the other serves as a negative-side contact. In the example shown in fig. 3, a plate spring contact is used for the first contact 124 and the second contact 125 to obtain a proper contact pressure. However, the present invention is not limited to this, and for example, spring probes may be used for the first contact 124 and the second contact 125. The contact exposed to the outside of the container of the present invention corresponds to the first contact 124 or the second contact 125.

As shown in fig. 4, the base-side contact portion 22 of the base 20 has an annular base portion 222 with a depressed center, a third contact 223 on the central bottom surface of the annular base portion 222, and a fourth contact 224 on the top surface of the annular base portion 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 concentrically, and the third contact 223 and the fourth contact 224 are different in height from each other. That is, the third contact 223 is at a lower position than the fourth contact 224.

When the spray container 10 is placed on the pedestal 20, the third contact 223 faces the top surface of the circular table portion 122, and contact (conduction) is generated between the first contact 124 and the third contact 223. Similarly, when the spray container 10 is placed on the pedestal 20, the fourth contact 224 faces the annular flat surface portion 123, and contact (conduction) is generated between the second contact 125 and the fourth contact 224.

In the contact structure between the spray container 10 and the pedestal 20 according to example 2, the circular table portion 122 and the circular ring-shaped flat surface portion 123 are arranged concentrically, and the third contact 223 and the fourth contact 224 are planar electrodes arranged concentrically. Therefore, regardless of the orientation in which spray container 10 is rotated on base 20, contact point contact can be obtained between container-side contact point 12 and base-side contact point 22.

However, the first to

fourth contacts

124, 125, 223, and 224 are usually plated to prevent wear and corrosion of the contacts. When the spray container 10 is rotated while being placed on the base 20, the contacts rub against each other, and the plating layer is easily removed. In silver ion water generating/spraying device 1 according to example 2, notch 121 formed in container side contact portion 12 and protrusion 221 formed in base side contact portion 22 are fitted to each other as described above, whereby spray container 10 can be prevented from rotating on base 20, and the plating layer of the contact can be prevented from coming off.

In the example shown in fig. 3, the number of notches 121 is 12, and in the example shown in fig. 4, the number of protrusions 221 is 4. Thus, the number of the notches 121 and the number of the protrusions 221 do not need to be the same, and it is sufficient if (the number of the protrusions 221) ≦ the number of the notches 121.

Further, notches 121 are formed at equal angular intervals along the outer peripheral edge of container-side contact portion 12. On the other hand, the projections 221 are preferably arranged at equal angular intervals in such a manner that the number thereof is a divisor of the number of the notches 121, but the projections 221 may not necessarily be arranged at equal angular intervals. However, when the angular interval between two adjacent notches 121 is defined as α (30 ° (-360 °/12) in the example of fig. 4), the angular interval β between two adjacent protrusions 221 is defined as an integral multiple of the angular interval α.

In this way, when the notches 121 and the projections 221 are fitted to prevent the rotation of the ejection container 10 on the base 20, the orientation of the ejection container 10 placed on the base 20 is freely rotated at an angular interval of 360 °/n, assuming that the number of notches 121 is n. Accordingly, when the user places the spray container 10 on the pedestal 20, it is not necessary to adjust the orientation of the spray container 10 to a specific direction, thereby improving convenience.

In the pedestal-side contact portion 22, the third contact 223 and the fourth contact 224 are different in height from each other, and a height difference is generated therebetween. This height difference prevents short-circuiting between contacts when water droplets (particularly water droplets of silver ionized water) fall onto the pedestal-side contact portions 22. That is, when the third contact 223 and the fourth contact 224 do not have a height difference on the same plane, the water droplets falling down to the pedestal-side contact portion 22 contact both the third contact 223 and the fourth contact 224, and there is a possibility that short-circuiting occurs between the contacts due to the water droplets. On the other hand, when there is a difference in height between the third contact 223 and the fourth contact 224, even if water drops fall onto the pedestal-side contact portion 22, the water drops can be blocked by the difference in height, and short-circuiting between the contacts due to the water drops can be prevented.

Further, by making the heights of the third contact 223 and the fourth contact 224 different, even if a finger or the like of the user erroneously touches the cradle-side contact portion 22, both the third contact 223 and the fourth contact 224 are not touched at the same time, and electric shock can be prevented.

Further, in the pedestal-side contact portion 22, a dehydration hole 225 is preferably provided in the central bottom surface of the annular pedestal portion 222 provided with the third contact 223 (see fig. 4a and 5). The dewatering hole 225 is preferably formed as a through hole, for example, so as to penetrate from the central bottom surface (recess) of the annular base portion 222 to the bottom surface of the base 20, by discharging water on the base-side contact portion 22 to the lower side of the base 20, thereby preventing water from accumulating on the central bottom surface of the annular base portion 222. Of course, the drain hole 225 is a member that drains water through a passage that does not affect the circuit board or the like in the pedestal 20.

In the contact structure described in embodiment 2, when the ejection container 10 is placed on the pedestal 20 and the container-side contact portion 12 and the pedestal-side contact portion 22 are fitted to each other, the first contact 124 and the third contact 223 are brought into contact with each other to be electrically connected to each other, and the second contact 125 and the fourth contact 224 are brought into contact with each other to be electrically connected to each other. It is preferable that the contacts do not contact each other until the container side contact portion 12 and the holder side contact portion 22 are completely fitted. That is, it is preferable that the contact point contact is generated only when the spray container 10 is completely placed on the pedestal 20.

Fig. 6 is a sectional view of the ejection container 10 placed on the pedestal 20 before the container-side contact portion 12 and the pedestal-side contact portion 22 are completely fitted to each other. In this state, although the spray container 10 contacts the pedestal 20 through the points a and B in the drawing, the spring contact as the first contact 124 does not contact the third contact 223. In addition, although not shown in fig. 6, at this time, the spring contact as the second contact 125 does not contact the fourth contact 224. According to this structure, for example, when spray container 10 is placed on base 20 in an empty state and spray container 10 is not completely placed on base 20 and is in a slightly floating state, incomplete conduction between the contacts can be prevented.

A proximity sensor (not shown) may be provided on the pedestal 20 to detect whether or not the spray container 10 is completely placed on the pedestal 20. That is, when the spray container 10 is not completely placed on the pedestal 20 and is floated, such a state may be detected by the proximity sensor.

In the above description, the notch 121 of the container side contact portion 12 and the protrusion 221 of the base side contact portion 22 are exemplified as a structure that can prevent the rotation of the ejection container 10 on the base 20. However, the present invention is not limited to this, and as shown in fig. 7, the following configuration may be adopted: at least two notches 126 are provided on the outer periphery of the bottom of the spray container 10, 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 projection 226 provided on base 20 face notch 126 provided on ejection container 10, projection 226 sandwiches the bottom of ejection container 10, and rotation of ejection container 10 can be prevented.

In the configuration shown in fig. 7, the number of notches 126 is 2, and in this case, the spray container 10 can be placed on the pedestal 20 in 2 orientations different from each other by 180 °. However, the number of the notches 126 is not limited to 2, and the orientation of the spray container 10 when it is placed can be increased by increasing the number of the notches 126. For example, if 4 notches 126 are provided at equal intervals on the outer periphery of the bottom of the spray container 10, the spray container 10 may be arranged on the base 20 in 4 orientations at intervals of 90 °.

(embodiment 3: electrode Structure inside spray Container)

In embodiment 3, the electrode structure inside the spray container 10 will be described. Fig. 8 is a longitudinal sectional view showing the structure in the spray container 10.

As shown in fig. 8, the spray container 10 includes, as external components constituting the external appearance thereof: a nozzle part (cap, injection part) 30, a connecting cover part 31, a shoulder cover part 32, a body cover part 33 and a bottom cover part 34. Further, the spray container 10 includes an electrode holding base 35 and a tube 36 as internal components.

In the ejection container 10, the shoulder cap portion 32, the body cap portion 33, and the bottom cap portion 34 constitute the appearance of a tank (storage portion) T that stores water, and the silver electrode portion 351 provided on the electrode holding base 35 is disposed at the bottom portion in the tank T. The water stored in the tank T elutes silver ions from the silver electrode unit 351 to generate silver ion water, and the generated silver ion water is sucked up by the pipe 36 and ejected from the head 11 of the nozzle unit 30. The tank T has an opening, and stores a liquid such as water injected from the opening.

As shown in fig. 8, the electrode holding base 35 is fixed and fixed to the upper surface side of the bottom cover portion 34 by screws or the like. The silver electrode portion 351 in the ejection chamber 10 is provided on the electrode holding base 35. As will be described later, the electrode holding base 35 is formed as a member different from the bottom cover 34, thereby facilitating the assembly of the silver electrode portion 351 to the first contact 124 and the second contact 125.

Fig. 9 is a view showing the electrode holding base 35, (a) is a plan view of the electrode holding base 35, (b) is a perspective view of the electrode holding base 35 viewed obliquely from above, and (c) is a schematic plan view showing the arrangement of the electrode plate 353 in the electrode holding base 35.

As shown in fig. 9, the electrode holding base 35 is constituted by a flange portion 352 and a silver electrode portion 351, the flange portion 352 being for seating on the bottom cover portion 34, the silver electrode portion 351 being disposed on the upper face side of the flange portion 352. The flange portion 352 is provided with a plurality of (4 in fig. 9) screw holes for fastening the electrode holding base 35 to the bottom lid portion 34. The silver electrode section 351 includes a pair of electrode plates 353 and a pair of electrode plate holders (electrode protection sections) 354 that support the electrode plates 353 from the outside. The electrode plate support 354 is a member that abuts against the electrode plate 353 to protect the electrode plate 353. The electrode plate support 354 corresponds to the protection portion of the present invention. The electrode plate 353 has a pair of opposing surfaces opposing the electrode plate 353 and an outer surface on the back surface of the opposing surfaces, and the electrode plate support 354 covers the outer surface of the electrode plate 353. The electrode plate support 354 may be provided so as to cover the entire outer side surface of the electrode plate 353. The electrode plate support 354 may be provided to protrude outward from the side of the electrode plate 353 to protect the side of the electrode plate 353. Since the electrode plate support 354 supports the electrode plate 353 while being in contact with the electrode plate 353, the protection of the electrode plate 353 can be secured. Further, since the electrode plate support 354 is configured to be supported in contact with the electrode plate 353, the accuracy of mounting the electrode plate 353 can be improved. Further, since the outer surface of the electrode plate 353 is covered by abutting against the electrode plate support 354, corrosion of the outer surface of the electrode plate 353 can be suppressed. Further, since the opposing surface of the electrode plate 353 is not covered with the electrode plate support 354, the opposing surface of the electrode plate 353 can be easily cleaned. Further, the opposite surface of the electrode plate 353 can be cleaned using a brush or the like. Further, since the opposing surface of the electrode plate 353 is not covered with the electrode plate support 354, visibility of the opposing surface of the electrode plate 353 is improved, and whether or not cleaning of the electrode portion is necessary can be easily confirmed. Further, the silver electrode portion 351 may have an electrode plate holder 355 for holding one end of the electrode plate 353 from the outside. The electrode plate holder 355 holds the electrode plate 353, for example, by providing a holding groove in the electrode plate holder 355 and inserting an end of the electrode plate 353 into the holding groove. The electrode plate support 354 and the electrode plate holder 355 may be integrally formed with each other. Further, the electrode plate 353 may be formed of a silver single body, or may also be formed of a material containing silver.

As shown in fig. 8, the electrode plate 353 has a substantially rectangular plate-shaped portion (flat plate portion) 353a and a leg portion 353b extending downward from one end of the plate-shaped portion 353a, and the plate-shaped portion 353a and the leg portion 353b are formed in a substantially L-shape. In the electrode plate 353, for example, the rod-shaped leg portion 353b may be attached to the plate-shaped portion 353a by welding or the like, but it is preferable that the plate-shaped portion 353a and the leg portion 353b are integrally formed together by using silver as a material. In this case, the electrode plate 353 can be easily formed by press working or the like from one flat silver plate (the leg portion 353b is also flat). One of the pair of electrode plates 353 is connected to a first contact 124 provided on the bottom cover 34 via a leg 353b, and the other is connected to a second contact 125 provided on the bottom cover 34 via the leg 353 b. The plate-shaped electrode plate 353 is formed in a thin plate shape having a thickness of 0.5 to 1.5mm, for example. By forming the electrode plate 353 into a thin plate shape, material cost can be reduced. Further, by forming the electrode plate 353 into a thin plate shape, the processing of the electrode plate 353 becomes easy. The gap between the pair of electrode plates 353 is, for example, 3 to 13 mm. By forming the gap between the electrode plates 353 narrow in this manner, foreign matter or the like is less likely to enter between the pair of electrode plates 353. Therefore, the risk of damage to the electrode plate 353 is reduced.

The plate-shaped portion 353a is preferably arranged to have an elongated shape (a horizontally long shape) whose longitudinal direction is a direction parallel to the tank bottom surface (bottom surface of the storage portion) 356 so that its plane intersects (more preferably is orthogonal to) the tank bottom surface 356. The plate-shaped portion 353a has a horizontally long shape, and thus the surface area can be increased while suppressing the height in the tank T. The plate-shaped portion 353a can efficiently generate silver ionized water in a short time by increasing the surface area thereof. Further, 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 less likely to float out of the water surface, and a reduction in the generation efficiency of silver ionized water can be suppressed.

The electrode plate 353 has one end portion (a part of the plate-shaped portion 353a and the leg portion 353 b) projecting above the electrode holding base 35 (i.e., inside the can T), and the other end portion (a part of the leg portion 353 b) projecting below the electrode holding base 35 (i.e., outside the can T) so as to receive power supply from outside the can T via the leg portion 353 b. The pair of electrode plates 353 is provided inside the can T, and includes a plate-shaped portion 353a formed in a plate shape and a leg portion 353b fixed to the can T protruding from a part of the side of the plate-shaped portion 353a to the outside of the can T. The leg 353b is preferably connected to the first contact 124 and the second contact 125 by a lead or solder. Alternatively, the leg 353b may be connected to the first contact 124 and the second contact 125 by a mechanical method such as pressure bonding. The space between the periphery of the leg 353B and the electrode holding base 35 is preferably sealed by a sealing portion (resin material) B (see fig. 13 (a) and (B)). By sealing the sealing portion B, the water resistance (sealing property) of the electrode holding base 35 can be improved, and electrolysis of the leg portion 353B which is the base end portion of the electrode plate 353 can be suppressed (prevented from being worn from the base end side). The seal portion B corresponds to the protection portion of the present invention.

In order to obtain more reliable waterproofing (sealing), the sealing portion B is preferably sealed so as to surround 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 shifted from one end of the plate-shaped portion 353 a. As a result, as shown in fig. 13 (a), even when the silver electrode portion 351 has the electrode plate holder 355, the sealing portion B can surround the entire periphery of the leg 353B while a gap is provided between the leg 353B and the electrode plate holder 355. Alternatively, as shown in fig. 13 (b), the leg 353b may be formed to be aligned with one end of the plate-shaped portion 353a, and a height difference may be provided on the holding surface of the electrode plate 353 of the electrode plate holder 355. With this configuration, the sealing portion B can surround the entire periphery of the leg 353B while a gap is provided between the leg 353B and the electrode plate holder 355.

The sealing portion B is preferably made of a resin material having high elasticity. Since the sealing portion B is formed of a material softer than the leg portion 353B and the tank T, the risk of damage to the leg portion 353B and the tank T can be reduced. When an impact or the like is applied to the electrode plate 353 in the can T by an external force, the impact can be absorbed by the sealing portion B.

The electrode plate 353 formed in a substantially L-shape has a leg portion 353b fixed to the electrode holding base 35 (can bottom surface 356) (connected to the first contact 124 and the second contact 125 via the leg portion 353 b), whereby the plate-shaped portion 353a can be disposed away from (floating up) the electrode holding base 35. That is, in the silver electrode portion 351, a gap is provided between the plate-shaped portion 353a and the electrode holding base 35. By providing a gap between the can bottom surface 356 of the can T and the lower portion of the plate-shaped portion 353a, liquid or the like can be prevented from being trapped between the pair of electrode plates 353.

When ions are generated by the silver electrode unit 351, a part of the silver ions eluted by electrolysis between the electrode plates 353 become fine particles (silver fine particles). If there is no gap between the plate-shaped portion 353a and the electrode holding base 35, the generated silver particles may be deposited between the electrodes to cause short circuit between the electrodes. Further, even if the short circuit between the electrodes is not achieved, there is a problem that the elution efficiency of silver ions is lowered by silver fine particles deposited between the electrodes, and the time required for generating silver ion water of a predetermined concentration becomes long.

In contrast, in the silver electrode portion 351 according to example 3, since a gap is provided between the plate-shaped portion 353a and the electrode holding base 35, silver fine particles generated by electrolysis are deposited in a space that becomes the gap under the plate-shaped portion 353a, and deposition of silver fine particles between the electrodes can be avoided. This can prevent short-circuiting between electrodes and a decrease in the elution efficiency of silver ions due to the deposited silver microparticles.

Further, in the spray container 10 according to embodiment 3, as shown in fig. 8, the lower end (the suck-up side) of the tube 36 that sucks up the silver ion water at the time of spraying is arranged so as to be located below the lower end of the plate-shaped portion 353 a. Thus, when the silver ionized water is ejected, the silver microparticles precipitated in the space below the plate-shaped portion 353a can be efficiently adsorbed by the tube 36. This can suppress the accumulation of silver microparticles even in the entire can T, and can more reliably avoid short-circuiting between electrodes and a decrease in the elution efficiency of silver ions due to the accumulated silver microparticles.

In order to generate silver ions appropriately in the silver electrode portion 351, it is necessary to maintain an appropriate distance between the electrodes of the pair of electrode plates 353. That is, by appropriately maintaining the distance between the electrodes, silver ionized water can be produced at a predetermined elution rate during electrolysis. For example, if the distance between the electrodes is too wide, the elution rate of silver ions becomes low, and the generation efficiency of silver ionized water becomes low. On the other hand, when the distance between the electrodes is too narrow, the elution rate of silver ions becomes too high, and it becomes difficult to adjust the concentration of silver ion water.

As shown in fig. 9, the pair of electrode plates 353 is preferably arranged obliquely (one electrode plate 353 is arranged at an inclination angle γ (for example, 0.64 °) with respect to the other electrode plate 353) in a figure-eight shape such that the proximal end side (terminal side) is wide and the distal end side is narrow as viewed from above. In such an inclined arrangement, the electrode plate 353 can be easily formed into a substantially L-shape by the plate-shaped portion 353a and the leg portion 353b extending downward from one end of the plate-shaped portion 353 a. By making the tip side of the pair of electrode plates 353 narrower than the base end side in this manner, the number of electrodes on the tip side of the electrode plates 353 can be easily reduced during electrolysis, and the electrode plates 353 can be used up to the end efficiently while preventing the consumption of the electrodes from the base end side (terminal side). Further, by disposing the pair of electrode plates 353 in a splayed shape, there are advantages in that the electrode plate support 354 molded with resin can be easily pulled out from the mold, visibility from above the electrode plate 353 is improved (wear of the electrode plate 353 can be easily confirmed from above), and the like.

It is difficult to properly maintain the inter-electrode distance between the pair of electrode plates 353 by the single electrode plate 353 as described above. Although it is conceivable to use tap water for the spray container 10, when electrolysis is performed using tap water, impurities (scale) 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 is also changed by the brush pressure.

In contrast, in the electrode holding base 35 according to example 3, since each electrode plate 353 is supported from the outside by the electrode plate support 354, the electrode plate 353 is disposed so as to contact the inside of the electrode plate support 354, and thus the inter-electrode distance can be easily and appropriately maintained. Further, since the electrode plate support 354 is disposed outside the electrode plate 353, when the can 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 appearance of the spray container 10 can be improved. The electrode plate support 354 may have a slightly larger area than the electrode plate 353, and the outer peripheral edge of the electrode plate support 354 may protrude outward beyond the outer peripheral edge of the electrode plate 353. This can prevent the tube 36 from contacting the outer peripheral edge of the electrode plate 353 from outside, for example, and can reliably protect the electrode plate 353.

The electrode plate support 354 is a member held by the electrode holding base 35 on the base end side, similarly to the electrode plate 353, and a gap is provided between the lower end of the electrode plate support 354 and the upper surface (the can bottom surface 356) of the electrode holding base 35. This prevents silver particles from being deposited between the electrodes of the electrode plate 353 by the presence of the electrode plate support 354. In order to increase the supporting strength of the electrode plate support 354, a support column 354a for connecting the electrode plate support 354 and the upper surface of the electrode holding base 35 may be provided at a position other than the base end of the electrode plate support 354. The pillars 354a are preferably formed in a fine columnar shape to suppress the accumulation of silver particles at the pillars 354a as much as possible.

In the above description, the lower end (suck-up side) of the tube 36 sucking up the silver ion water at the time of ejection is located below the lower end of the plate-shaped portion 353a, but the lower end of the tube 36 is preferably located outside the can T, and more preferably located on the tip side of the pair of electrode plates 353 (on the opposite side to the leg portions 353 b). By disposing the tube 36 in this manner, the lower end of the tube 36 can be securely positioned below the plate-shaped portion 353a, and the silver microparticles generated after electrolysis can be easily adsorbed. The thickness of the tube 36 is preferably larger than the inter-electrode distance of the electrode plate 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). Further, the diameter of the tube 36 is formed larger than the gap between the pair of electrode plate supports 354, whereby the protection of the counter electrode plate 353 can be secured. The spray container 10 may have, for example, the following configuration so as to reliably dispose the tube 36 as described above.

As a first configuration example, it is conceivable to provide a member (for example, the shoulder cap portion 32) for joining the nozzle portion 30 and the tank T with a member for guiding the tube 36 outward so that the tube 36 is positioned on the outer side in the tank T. Specifically, as shown in fig. 10, a guide hook 321 is provided on the inside of the shoulder cover 32, the pipe 36 can be hooked by the guide hook 321, and the pipe 36 can be guided to the outside in the tank T by the guide hook 321.

As a second configuration example, it is conceivable to set the length of the pipe 36 such that the height of the outer peripheral portion is lower than the height of the central portion (for example, a groove portion along the outer periphery of the tank bottom surface 356) in the tank bottom surface 356 of the spray container 10, and the lower end of the pipe 36 is located lower than the center of the tank bottom surface 356. In this case, even if the lower end of the pipe 36 comes near the center of the tank bottom surface 356, the pipe 36 can be automatically moved outward by the elastic force of the pipe 36.

As a third configuration example, a mode in which the lower end of the pipe 36 is stopped at an appropriate position is provided in the tank bottom surface 356 of the spray container 10 may be considered. Specifically, as shown in fig. 11, a positioning plate 331 is provided inside the body cover 33, and when the nozzle unit 30 is attached to (screwed into) the can 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).

(embodiment 4: display Lamp)

In the silver ion water generating/spraying device 1 according to embodiment 4, for example, the display lamp (display portion) is turned on at the time of electrolysis so that the user can be notified of information during electrolysis by the display lamp (display portion) on the pedestal 20.

Fig. 12 is a view showing an example of the structure of the pedestal 20 according to example 4, where (a) is an exploded perspective view of the pedestal 20, and (b) is a perspective view of the display lamp 20 included in the pedestal 20 as viewed obliquely from below. As shown in fig. 12, the base 20 includes an annular light guide 24 and a plurality of light emitting elements 25 (for example, LEDs) inside a base housing 23 (an upper housing 231 and a lower housing 232). In the pedestal 20 shown in fig. 12, the annular light guide 24 and the light emitting element 25 function as a display lamp.

As shown in fig. 12 b, the annular light guide 24 has a planar upper surface and a plurality of (4 in fig. 12) inclined protrusions 241 are formed on a lower surface thereof. The plurality of 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 one end of the inclined protrusion 241 (the end on the side where the thickness of the annular light guide 24 is increased by the inclined protrusion 241).

The light emitting element 25 is disposed below the annular light guide 24 such that the light emitting surface thereof faces the vertical surface of the step 242. The light emitted from the light emitting element 25 enters the annular light guide 24 from the step 242 in the horizontal direction, and is further reflected upward on the inclined surface (lower surface) of the inclined protrusion 241. Accordingly, the annular light guide 24 can emit light in a circular shape as uniformly as possible even with a small number of light emitting elements 25. Even when water reaches the annular light guide 24, the water reaches the inclined projection 241 and drops to the lower portion, and therefore, the light emitting element 25 is disposed at a constant distance from the step 242, and direct leakage of water to the light emitting element 25 can be avoided.

The upper surface of the annular light guide 24 is exposed on the upper surface of the base 20, and the upper surface is covered with a waterproof seal 26. The waterproof seal 26 covers the entire upper surface of the base 20 except for the base-side contact portion 22, and covers not only the annular light guide 24 but also the operation button 21. Thereby, the waterproof seal 26 prevents water from entering the inside of the pedestal 20.

The inner diameter of the annular light guide 24 is set larger than the outer diameter of the bottom of the ejection container 10. The operation button 21 is disposed on the outer peripheral side of the annular light guide 24. When the ejection chamber 10 is disposed on the base 20, the annular light guide 24 is disposed on the outer peripheral side of the ejection chamber 10 so as to surround the ejection chamber 10. Thus, the user can recognize the lighting of the indicator lamp (light emission of the ring-shaped light guide 24) from any one of the four directions. Further, by bringing the annular light guide 24 close to the ejection container 10, the light irradiated by the annular light guide 24 can be reflected by the side surface of the ejection container 10. In this case, the lighting of the display lamp can be easily recognized even in the lateral direction. In addition, when the tank T of the spray container 10 is transparent, bubbles generated during electrolysis can be made conspicuous by light, and the user can easily recognize the state of electrolysis.

The plurality of light emitting elements 25 are mounted on a common circuit board 27 and are controlled to emit light. Then, by light emission control in which the light emission timing of each light emitting element 25 is changed, the change in the electrolytic state can also be communicated to the user. For example, it is considered that a high concentration/low concentration electrolysis pattern, time to completion of electrolysis, electrode life, and the like can be transmitted by a change in the light emission timing of the light emitting element 25.

In the silver ionized water producing and spraying apparatus 1 according to embodiment 4, for example, it is considered that the operation button 21 is not accepted again until the electrolysis is completed after the operation button 21 is turned on and the electrolysis is started. This is to prevent the operation button 21 from being turned off during electrolysis to reset the electrolysis time. That is, by preventing the resetting of the electrolysis time, the electrolytic concentration of the generated silver ion water can be fixed (a predetermined electrolytic concentration is obtained).

In this case, it is preferable that the user be notified of the state during electrolysis and the completion of electrolysis by lighting control of the display lamp. Specifically, it is conceivable that the indicator lamp is turned on and off at predetermined intervals (for example, at intervals of 1 second) during electrolysis (for example, 60 seconds), and the indicator lamp is turned on when electrolysis is completed. It is preferable that the display lamp indicating completion of electrolysis be turned on for a fixed time (e.g., 1 minute). In the lighting period of the indicator lamp after completion of electrolysis, the user can be prevented from overlooking and the signal of completion can be reliably transmitted by setting the lighting period for a long time.

Example 5 Container Structure for spray Container interior

In embodiment 5, a structural example of a tank T suitable for the spray container 10 will be described. In the ejection container 10, as described above, the shoulder cap portion 32, the body cap portion 33, and the bottom cap portion 34 form the appearance of the tank T for storing water. That is, the tank T of the spray container 10 is not integrally formed as one component, but is configured by combining a plurality of components. This is because there are the following advantages in the spray container 10.

First, the structure of separating the body cover 33 and the bottom cover 34 is suitable for disposing the electrode holding base 35 on the bottom of the can T. That is, when the body cover 33 and the bottom cover 34 are separated, the electrode holding base 35 can be easily arranged on the bottom of the can T by further attaching the body cover 33 after attaching the electrode holding base 35 to the bottom cover 34. Further, in the spray container 10 shown in fig. 8, a packing 40 for preventing water leakage between the body cover portion 33 and the bottom cover portion 34 is provided.

For example, the assembly of the body cover 33, the bottom cover 34, and the electrode holding base 35 can be performed by the following steps.

First, the electrode plate 353 is attached to the electrode holding base 35. Specifically, the leg 353B of the electrode plate 353 is inserted into the opening formed in the electrode holding base 35 from above, a resin material or the like is filled around the leg 353B of the opening, and the sealing portion B is formed between the can T and the periphery of the leg 353.

Subsequently, the leg portion 353b of the electrode plate 353 is electrically connected to the connection portion 341. The connection portion 341 is connected to the first contact 124, the second contact 125, and the electrode plate 353. The connection portion 341 corresponds to a protection portion of the present invention. For example, the first contact 124 and the second contact 125 are attached to the connection portion 341 after the electrode plate 353 is attached. The electrode plate 353 may be attached to the connection portion 341 after the first contact 124 and the second contact 125 are attached. By connecting the first contact 124, the second contact 125, and the electrode plate 353 via the connecting portion 341, the load applied to the first contact 124, the second contact 125, or the leg portion 353b of the electrode plate 353 can be reduced. For example, when the ejection container 10 is mounted on the base 20, the force acting on the first contact 124 and the second contact 125 acts on the leg portion 353b via the connecting portion 341. That is, the connection portion 341 has a force to reduce 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 lead wire or the like can further reduce the load acting on the first contact 124, the second contact 125, or the leg 353 b. For example, the first contact 124, the second contact 125, and the leg 353b may be provided at different positions on a plane (horizontal plane) parallel to the can bottom surface 356 formed at the bottom of the can T. By providing the first contact 124, the second contact 125, or the leg 353b at different positions, the load applied to the leg 353b can be further reduced.

The electrode holding base 35 to which the electrode plate 353, the connecting portion 341, the first contact 124, and the second contact 125 are attached is attached to the body cover portion 33. A gasket 40 is provided between the electrode holding base 35 and the body cover 33. The electrode holding base 35 and the gasket 40 are fixed to the body cover 33 by the bottom cover 34 in a state pressed by the body cover 33. The bottom cover portion 34 and the body cover portion 33 form the outline of the ejection container 10. The electrode holding base 35 is accommodated in a space surrounded by the bottom cover 34 and the body cover 33. The bottom cover portion 34 and the body cover portion 33 are fixed to the outer side of the gasket 40 in the circumferential direction by screws 42 or the like. The screw 42 is inserted from the lower surface side of the bottom cover 34, passes through a screw hole provided in the electrode holding base 35, and is connected to the body cover 33.

Next, the structure of separating the shoulder cover portion 32 and the body cover portion 33 is suitable for improving the cleanliness of the tank T and the ease of water supply. That is, the upper portion of the tank T connected to the nozzle portion 30 needs to be formed in a narrow neck shape. At this time, if the shoulder cover portion 32 and the body cover portion 33 are formed integrally (inseparably), it is difficult to clean the inside of the can T from the upper portion of the narrow-necked can T. Since the shoulder cover portion 32 and the body cover portion 33 are separable, either one of the shoulder cover portion 32 and the body cover portion 33 can be easily cleaned (can be cleaned from a wide opening side). In addition, when water is supplied to the spray container 10, water can be supplied from a wide opening by detaching the shoulder cap portion 32 from the body cap portion 33, and water supply is facilitated. In addition, the shoulder cap 32 is detachable, so that the nozzle 30 as a consumable can be easily replaced.

It is preferable that no undercut be formed in the upper portion of the body cover portion 33 at the joint between the shoulder cover portion 32 and the body cover portion 33. That is, as shown in fig. 8, the upper portion of the body cover 33 is not reduced in diameter compared to other portions (when the diameter of the upper portion is reduced, an undercut (level difference) is formed in the inner surface of the body cover 33), and a male screw is formed at an upper edge portion formed in a slightly thick wall (a female screw is formed at a lower edge portion of the shoulder cover 32). By not forming an undercut in the body cover 33 in this way, the formability of the body cover 33 can be improved, and the inside of the tank T can be easily cleaned.

Further, in the spray container 10 shown in fig. 8, a packing 41 for preventing water leakage from between the shoulder cover portion 32 and the body cover portion 33 is provided. As shown in fig. 8, the gasket 41 is preferably disposed in contact with the upper end of the body cover portion 33. For example, as shown in fig. 8 as an inappropriate example, when the packing 41 is disposed near the lower end of the shoulder cover portion 32, water may accumulate in a gap between the shoulder cover portion 32 and the body cover portion 33 above the packing 41. For example, water accumulated in the gap may overflow when the shoulder cover portion 32 is removed from the body cover portion 33 on the base 20, and the base 20 may be wet. The gasket 41 disposed in contact with 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.

It is preferable that at least the side surface (i.e., the body cover 33) of the tank T in the spray container 10 be a transparent or translucent portion. This improves visibility of the water level in the tank T. If the visibility of the water level is good, the following advantages are provided: the side of the tank T is provided with a water level scale with a specified amount so as to easily put a fixed amount of water, and whether the water is before or after electrolysis or the like can be easily judged according to the turbidity condition of the water.

(embodiment 6: operation control example)

In embodiment 6, an operation control example suitable for the silver ionized water producing spray apparatus 1 will be described.

In the silver ion water generating/ejecting apparatus 1 according to example 6, a current sensor and a voltage sensor for detecting the current and voltage between the electrodes of the silver electrode portion 351 may be provided in the power supply circuit on the pedestal 20 side, and the electrolytic 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 depending on the hardness of water in the tank T and the water temperature, and the electrolytic concentration of the silver ion water to be produced differs even if electrolysis is performed for the same time in the same amount of water. On the other hand, if the adjustment for suppressing the fluctuation of the electrolytic current is performed based on the detection result of the sensor, the electrolytic concentration of the silver ion water can be stabilized in a wide range in accordance with the hardness and the water temperature of the water in the tank T.

It is also conceivable to compare the current and voltage between electrodes based on the detection result of the sensor by comparing the last electrolysis and the present electrolysis that are closest to each other (for example, within 1 hour) and determine whether or not the electrolysis is completed. For example, if the current of the current electrolysis is larger than the reference value as compared with the current of the previous electrolysis, it is possible to determine that the electrolysis of the water in the tank T is completed, and the current electrolysis may be cancelled based on the determination.

Example 7 example of the shape of silver electrode section

In example 7, a modified example of the silver electrode portion 351 suitable for the ejection chamber 10 will be described.

In example 3 described above, the electrode plate 353 is constituted by 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.

Fig. 14 (a) and (b) are schematic plan views of the silver electrode portion 351 when the bottom of the can T is viewed from above. As shown in fig. 14 (a) and (b), the plate-shaped portion 353a may be formed by bending a single flat plate-shaped silver plate linearly or curvilinearly in a plan view (may be bent linearly or curvilinearly in combination). Of course, when the plate-shaped portion 353a is formed in a curved shape, the electrode plate support 354 is also formed in a shape conforming to the plate-shaped portion 353 a. Thus, by forming the plate-shaped portion 353a in a curved shape, the surface area of the plate-shaped portion 353a can be increased while suppressing the maximum length of the plate-shaped portion 353a in the longitudinal direction. That is, the electrode plate 353 having a large surface area and high silver ion water generation efficiency can be compactly housed in the can T.

Further, the pair of curved plate-shaped portions 353a is preferably disposed point-symmetrically with respect to the center point of the tank T in a plan view. In this case, the inclination with respect to the radial direction of the tank T is the same in both end portions of the pair of plate-shaped portions 353 a. Thus, for example, when water is discharged into the tank T and stirred so that a water flow is generated in the direction of arrow R during washing of the inside of the tank T, the water flow is likely to enter between the electrodes from both end portions of the plate-shaped portion 353 a. By thus making the water flow enter between the electrodes, the cleaning effect against the impurities (scales) adhering to the surface of the plate-shaped portion 353a can be improved.

The structure may be as follows: when water flows between the electrodes from both ends of the plate-shaped portion 353a, instead of the electrode plate holder 355 holding the end of the electrode plate 353, a holding protrusion 357 erected upward from the tank bottom surface 356 is provided near the center in the longitudinal direction of the pair of plate-shaped portions 353 a. By providing the holding projection 357, each electrode plate 353 can be held with the plate-shaped portion 353a interposed between the electrode plate support 354 and the holding projection 357. The holding projection 357 also has a function of preventing the electrode plates 353 from falling inward, and the electrode plates 353 from coming into contact with each other and short-circuiting.

In order to facilitate the entry of water flow between the electrodes from both ends of the electrode plate 353, the electrode plate 353 may have a structure as shown in fig. 15 (a) or (b). In fig. 15 (a), the plate-shaped portion 353a is formed by curving the plate-shaped portion in a curved manner, and the curvature of the both end portions is larger than that of the central portion. In this case, the inclination with respect to the radial direction of the tank T is increased by increasing the curvature of both ends of the plate-shaped portion 353a, and the water flow in the arrow R direction easily enters between the electrodes from both ends of the plate-shaped portion 353 a. Further, the central portion of the plate-shaped portion 353a has a small curvature and thus has a small flow path resistance, and the water flow entering from both end portions easily reaches the central portion.

In fig. 15 (b), the plate-shaped portions 353a are formed by curving in a curved line, and at the end portions of the pair of plate-shaped portions 353a, the end portion of one plate-shaped portion 353a is arranged radially outward of the end portion of the other plate-shaped portion 353a, and a "receiving" structure is provided in which the water flow in the direction of arrow R easily enters between the electrodes from the end portion of the plate-shaped portion 353 a. For example, the end of one plate-shaped portion 353a is formed to be inclined by substantially 90 degrees in the radial direction with respect to the end of the other plate-shaped portion 353a, thereby covering the end of the other plate-shaped portion 353a, and the above-described effect is further enhanced. Further, for example, the end of one plate-shaped portion 353a is formed to be inclined by substantially 90 degrees in the radial direction with respect to the other plate-shaped portion 353a, and the curvature of the end side of the one plate-shaped portion 353a is formed to be smaller than the curvature of the end side of the other plate-shaped portion 353a, whereby the end of the other plate-shaped portion 353a is covered, whereby the above-described effect is further enhanced.

In the "receiving" structure in which the water flow in the direction of arrow R is easily introduced between the electrodes from the end of the plate-shaped portion 353a, as shown in fig. 16(a) and (b), the water flow may be provided not depending on the shape of the plate-shaped portion 353a but depending on the shape of the electrode plate support 354. That is, in fig. 16(a) and (b), at the end portions of the pair of electrode plate supports 354, an extending portion 354b extending in the direction toward the outer periphery of the can T and toward the other electrode plate support 354 is provided at the end portion of one electrode plate support 354, and a "receiving" structure is provided in which the water flow in the direction of arrow R easily enters between the electrodes from the end portion of the plate-shaped portion 353 a. The extension portion 354b may be formed in a linear shape as shown in fig. 16(a), or may be formed in a curved shape as shown in fig. 16 (b).

In the example shown in fig. 14 and 15, the plate-shaped portions 353a of the electrode plate 353 have a shape that is periodically bent so as to cross left and right along the longitudinal direction, but the plate-shaped portions 353a may be non-periodically bent.

For example, as shown in fig. 17 (a) and (b), the plate-shaped portion 353a may be a simple shape that is bent once. In this case, the total length of the pair of plate-shaped portions 353a may be different from the length shown in fig. 17 (a), or may be the same as the length shown in fig. 17 (b).

As shown in fig. 18, the plate-shaped portion 353a may have a spiral shape that is bent a plurality of times in either the left or right direction. When the plate-shaped portion 353a has a spiral shape as shown in fig. 18, the silver electrode portion 351 can be arranged in a two-dimensional wide space in a plan view. Therefore, the electrode plate 353 having a larger surface area and high silver ion water generation efficiency can be compactly housed in the can T.

The plate-shaped portion 353a shown in fig. 18 may be formed by bending one plate-shaped electrode plate a plurality of times, or may be formed by joining a plurality of plate-shaped electrode plates. Since the plate-shaped electrode plate is used in any method, the production cost of the electrode plate 353 can be reduced.

The plate-shaped portion 353a of the electrode plate 353 shown in fig. 14, 15, 17, and 18 has an elongated shape (horizontally long shape) whose longitudinal direction is a direction parallel to the can bottom surface 356, in a projected shape in the horizontal direction (a projected shape in which the projected length in the horizontal direction is maximized). That is, the plate-shaped portion 353a has a shorter shape of a second side intersecting with a first side parallel to the can bottom surface 356 of the can T than the first side. Thus, similar to the plate-shaped portion 353a shown in example 3, the surface area can be increased while suppressing the height of the plate-shaped portion 353a in the tank T.

As shown in fig. 19, the electrode plate 353 may be provided with a hollow portion 353c penetrating the plate-shaped portion 353a in the thickness direction. The hollow portion 353c is provided as a notch extending along the longitudinal direction (i.e., the horizontal direction) of the plate-shaped portion 353a, and is a trapezoidal notch portion having a width that increases from the end provided at the leg portion 353b toward the end opposite to the leg portion 353 b. In the hollow portion 353c, an end portion opposite to the leg portion 353b is open, and a circular hollow is provided at an end portion opposite to the leg portion 353 b.

By providing the hollow portion 353c in the plate-shaped portion 353a, the ratio of the surface area of the plate-shaped portion 353a deposited can be increased. This makes it easy to efficiently produce silver ion water having a high concentration. The circular hollow provided at the end of the hollow portion 353c has a function of preventing the electrode from being damaged due to the electrode in the plate-shaped portion 353a being dissolved, so that the electrode plate 353 can be used for a long time.

In fig. 19, the notch serving as the hollow portion 353c is provided only in the plate-shaped portion 353a, but the same notch may be provided in the electrode plate support 354. When the electrode plate support 354 is also provided with the notch, a cavity is formed to penetrate both the plate-shaped portion 353a and the electrode plate support 354 in the thickness direction, so that water easily passes through the electrode during cleaning of the can T of the spray container 10, and the cleaning effect can be improved.

As shown in fig. 20 (a) and (b), a groove 353d that does not penetrate through 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 a surface opposite to the contact surface with the electrode plate support 354, and the contact surface with the electrode plate support 354 is the back surface of the plate-shaped portion 353 a. By providing the groove portions 353d in the plate-shaped portion 353a, the ratio of the surface area to the deposition of the plate-shaped portion 353a can be increased, and silver ionized water with high concentration can be easily and efficiently generated.

The groove 353d is formed along the longitudinal direction (i.e., horizontal direction) of the plate-shaped portion 353a, and particularly, the groove lower surface is preferably formed as an inclined surface so as to descend from the back surface to the front surface of the plate-shaped portion 353 a. By inclining the groove bottom surface of the groove portion 353d, scale generated in the groove portion 353d is easily dropped, and clogging of the groove portion 353d by scale can be suppressed. The groove top surface of the groove portion 353d may be inclined as in the groove bottom surface (see fig. 20 a) or may be a horizontal surface (see fig. 20 b).

Further, in the plate-shaped portion 353a of the electrode plate 353, the cross section may be formed into a substantially trapezoidal shape so that the thickness of the upper end side is thin and the thickness of the lower end side is thick. By forming the plate-shaped portion 353a to have a substantially trapezoidal cross section, it is difficult for the plate-shaped portion 353a to collapse (fall on the upper end side) and short circuit due to collapse to occur with wear (thinning) of the electrode, so that the electrode plate 353 can be used for a long time.

The container and the container holder according to the present invention can be described as follows. Another embodiment of the present invention relates to a metal ion water generating container (container) including a tank that stores a liquid and has an opening, and a metal electrode unit that is disposed in the tank, the metal electrode unit including a pair of electrode plates that are disposed apart from each other and that are disposed so as to be in contact with the liquid stored in the tank, the electrode plates being formed of a material containing a metal that can elute metal ions having an antibacterial action in the liquid.

According to the above configuration, the metal ion water generating container has the metal electrode portion in the tank, and the metal ion having the antibacterial action in the liquid (usually, water) is eluted in the container by supplying electricity between the electrodes of the pair of electrode plates including the metal electrode portion, so that the metal ion water having a high concentration can be generated in a short time.

In the metal ion water generating container, one end portion of the electrode plate may be fixed to the can, and a space between a periphery of the one end portion of the electrode plate and the can may be sealed with resin.

According to the above configuration, the periphery of the fixed position of the electrode plate is sealed with resin, and the water resistance (sealing property) between the electrode plate and the can be improved. Further, electrolysis of the base end portion (portion connected to the terminal) of the electrode plate can be suppressed (prevented from being worn from the base end side).

In the metal ion water producing container, the pair of electrode plates may be integrally formed of a silver-containing material.

In the metal ion water generating container, at least a side surface of the tank may be transparent or translucent.

According to the structure, the advantages are as follows: the visibility of the water level in the tank is good, and a predetermined amount of water level scale is provided on the side surface of the tank to facilitate the introduction of a fixed amount of water, or whether the water is before or after electrolysis is easily judged by the turbidity of the water.

In the metal ion water generating container, the metal electrode portion may be provided at a position visible from the outside through a side surface of the tank.

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

In the metal ion water generating container, the electrode plates may have a substantially rectangular flat plate portion and leg portions extending downward from one end of the flat plate portion, and a pair of the electrode plates may be disposed so as to face the flat plate portion.

In the metal ion water generating container, the flat plate portion of the pair of electrode plates may be inclined so that a proximal end side having a terminal is wider and a distal end side is narrower.

According to the above configuration, the tip side of the pair of electrode plates is made narrower than the base end side, so that the number of electrodes on the tip side of the electrode plates can be easily reduced during electrolysis, and the electrode plate can be used to the end efficiently while preventing the consumption of the electrode from the base end side (terminal side).

In the metal ion water generating container, the flat plate portion of the electrode plate may be disposed away from a bottom portion of the tank.

According to the above configuration, by separating the electrode plate from the bottom of the can, a gap can be provided between the flat plate portion and the bottom of the can, and metal fine particles (silver fine particles) generated by electrolysis are deposited in a space which becomes the gap below the flat plate portion, and deposition of metal fine particles between the electrodes can be avoided. This can prevent short-circuiting between electrodes and a decrease in the efficiency of elution of metal ions due to the deposited metal fine particles.

In the metal ion water generating container, the pair of electrode plates may be supported by a support member from the outside.

According to the above configuration, each electrode plate is supported from the outside by the support body, and the inter-electrode distance can be easily and appropriately maintained.

In addition, the metal ion water generating container may include an ejecting portion that ejects the liquid stored in the tank.

In the metal ion water producing container, the electrode plate may have a substantially rectangular flat plate portion and a leg portion extending downward from one end of the flat plate portion, and the electrode plate may be disposed away from the tank, and a lower end of a pipe that sucks up the liquid stored in the tank and sends the liquid to the spouting portion may be located below a lower end of the flat plate portion.

According to the above configuration, when the metal ion water is sprayed, the metal fine particles precipitated in the space which becomes the gap under the flat plate portion can be efficiently sucked up by the pipe, and the deposition of the metal fine particles in the entire tank can be suppressed. This makes it possible to more reliably avoid short-circuiting between electrodes and a decrease in the efficiency of elution of metal ions due to the deposited metal fine particles.

In addition, a metal ion water generating apparatus (container placing member) according to another aspect of the present invention is constituted by the metal ion water generating container described above and a base on which the metal ion water generating container is placed, and the base is further provided with a power supply portion capable of supplying power to the metal electrode portion of the metal ion water generating container when the metal ion water generating container is placed on the base.

According to the above configuration, by providing the power supply portion on the pedestal, it is possible to reduce the weight of the metal ion water generating container, and to improve safety (prevention of electric shock) of a user when spraying the metal ion water.

The metal ion water generating apparatus is configured to supply power from the pedestal to the metal ion water generating container by a contact power supply method, wherein the metal ion water generating container has a container side contact portion formed in a concave shape on a bottom surface, and the pedestal has a pedestal side contact portion formed in a convex shape on an upper surface, and when the metal ion water generating container is placed on the pedestal, the container side contact portion and the pedestal side contact portion are fitted to each other, whereby the metal ion water generating container can be positioned on the pedestal.

According to the above configuration, by positioning the metal ion water generating container on the base, the contact point between the container side contact point portion and the base side contact point portion can be firmly contacted (power supply can be reliably performed).

In the metal ion water generating apparatus, the container-side contact portion and the pedestal-side contact portion may be configured to prevent the metal ion water generating container from rotating on the pedestal when the container-side contact portion and the pedestal-side contact portion are fitted to each other.

According to the above configuration, the metal ion water generating container can be prevented from rotating on the base, and the plating layer can be prevented from dropping due to friction of the contact.

In the metal ion water generating apparatus, the metal ion water generating container may include a jetting portion that jets the liquid stored in the tank, and when the metal ion water generating container is placed on the base, a tip of a nozzle of the jetting portion may be located outside an outer periphery of the base as viewed from above.

According to the above configuration, even if the metal ion water attached to the tip of the head drops, the dropped metal ion water can be prevented from splashing on the pedestal.

In the metal ion water generator, the base may have a dewatering hole for discharging water on the base-side contact point portion downward of the base.

According to the above configuration, water can be prevented from accumulating on the pedestal side contact portion.

In the metal ion water generating apparatus, the pedestal may have a display lamp, and the display lamp may be disposed on an outer peripheral side of the metal ion water generating container when the metal ion water generating container is placed on the pedestal.

According to the above configuration, the user can be notified of the electrolytic state of the metal ion water generator and the like by the light emission control of the display lamp.

In the metal ion water generating apparatus, the display lamp may be disposed so as to surround the metal ion water generating container.

According to the above configuration, the user can recognize the lighting of the display lamp from any one of the four directions.

In the metal ion water generator, an operation button to be operated when starting electrolysis in the metal ion water generator may be provided on the pedestal, and the operation button may be disposed on an outer peripheral side of the display lamp.

In order to solve the above problem, an injection device according to a third aspect of the present invention includes: a tank storing a liquid; an electrode protruding toward the inside of the can and formed of a silver-containing material; an ejection part ejecting the silver ionized water generated by the electrode.

Further, a container according to the present invention includes: a storage section having an opening and storing a liquid; a pair of electrode plates having a plate-shaped portion provided inside the reservoir and formed in a plate shape, and legs fixed to the reservoir and protruding from a part of edges of the plate-shaped portion to the outside of the reservoir; and a protection part for protecting the electrode plate. The protective part is a component of the protective electrode plate, and in the above embodiment, has the seal part, the electrode protective part, or the connection part. Further, the protector reduces the risk of damage to the electrode plate, for example, when a finger, a bar-shaped elongated tool, or the like is directly brought into contact with the electrode plate, or when an impact or the like generated when the container is placed on the pedestal is transmitted to the electrode plate. For example, a gap is provided between the bottom surface of the reservoir and the lower portion of the plate-shaped portion. For example, the liquid supply device includes a cap covering the opening, and a tube attached to the cap and through which the liquid flows, and the diameter of the tube is formed larger than the gap between the pair of electrode plates. For example, the contact exposed to the outside of the container is provided, and the protection portion includes a connecting portion connecting the contact and the leg portion. For example, the contact and the leg are provided at different positions on a plane parallel to the bottom surface of the storage section. For example, the protector includes an electrode protector covering outer surfaces of the pair of electrode plates. For example, the protection portion includes a sealing portion that is interposed between the periphery of the leg portion and the storage portion and is formed of a material softer than the storage portion. For example, the electrode plate is formed of a silver-containing material. For example, in the plate-shaped portion, a second side intersecting with a first side is formed shorter than the first side parallel to the bottom surface of the reservoir.

The embodiments disclosed herein are all examples in all aspects and are not to be construed as limiting. Therefore, the technical scope of the present invention is defined not by the embodiments described above but by the description of the scope of the claims. Further, the scope of the present invention includes all modifications within the meaning and range equivalent to the claims.
