Hereinafter, embodiments of the present invention will be described in detail.
Example 1
First, the structure of the water treatment tool of Example 1 will be described with reference to the drawings.
FIG. 1 is a front view showing the water treatment tool of Example 1, FIG. 2 is a side view of the water treatment tool, FIG. 3 is a cross-sectional plan view taken along the line AA in FIG. It is a perspective view which shows the state before an assembly | attachment.

  That is, the water treatment tool of Example 1 is formed so that two kinds of different metals having different ionization tendencies and / or potentials are brought into close contact with each other and a contact boundary portion between the two kinds of different metals is in contact with water. With this configuration, when a local battery is formed at the contact boundary in water and the second metal 2 having a higher ionization tendency and / or a lower potential is oxidized, the metal ions are eluted into the water to This is a water treatment tool for adding a predetermined function, and is composed of a first metal 1 and a second metal 2.

More specifically, as shown in FIGS. 1 and 3, the first metal 1 is formed so that the gap between the wires is substantially the same as the diameter of the wire, and as shown in FIG. The end surface is composed of a pair of bottomed coil springs (coil spring-like metals) 11 and 12 having a structure closed by bottom members 11a and 12a formed by bending the end portions of the wire inward.
In addition, both the bottomed coil springs 11 and 12 are formed with outward bent portions 11b and 12b in which ends of the wire on the opening end face side are bent outward.
The second metal 2 is composed of a round bar 21 having the same outer diameter as the inner diameter of the bottomed coil springs 11 and 12 constituting the first metal 1 or an outer diameter larger than that.

  And the water treatment tool of this Example 1 is made to insert the both ends of the 2nd metal 2 of a round bar in the both bottomed coil springs 11 and 12 from the state before an assembly | attachment shown in FIG. From this state, the ends of the wire rods on the open end sides of the two bottomed coil springs 11 and 12 are integrated by screwing them together within the opening distance between the mating wire rods, as shown in FIGS. In addition, two kinds of different metals (first metal 1 and second metal 2) having different ionization tendency and / or potential are in close contact with each other. In FIG. 4 of the first embodiment, an example is shown in which the opening distance between the wires constituting the two bottomed coil springs 11 and 12 is wider than the diameter of the wires.

  In Example 1, the bottomed coil springs 11 and 12 that are the first metal 1 are made of iron (Fe), and the round bar 21 that is the second metal 2 has a higher ionization tendency than iron (Fe). And magnesium (Mg) which is a low potential metal.

Next, operations and effects of the first embodiment will be described.
Since the water treatment tool of Example 1 is configured as described above, if this water treatment tool is simply submerged in the water to be treated, magnesium (Mg) alone oxidizes and corrodes in the water. In the case of magnesium (Mg) alone, an oxide film is formed, so that the elution of metal ions is stopped. However, in this Example 1, it is intended to prevent corrosion of iron (Fe), which is the first metal 1 having the smaller ionization tendency or the higher potential, of the two kinds of different metals 1 and 2 and / or the lower potential. An oxide film is formed by sacrificial corrosion action of magnesium (Mg), which is a second metal 2 with a high ionization tendency and / or a lower potential that moves electrons from the second metal 2 to the higher metal. Without being present, magnesium ions are permanently and efficiently eluted from magnesium (Mg), which is the second metal 2 having the higher ionization tendency and / or the lower potential.

  Therefore, for example, by applying the water treatment tool of Example 1 to tap water used for various purposes, magnesium ions are combined with free chlorine contained in tap water to form magnesium chloride (a component of bittern). Since it can be changed, the harmful effects of chlorine can be eliminated.

Moreover, by applying the water treatment tool of Example 1 to water contained in a vase, a vase, or the like, magnesium hydroxide (MgOH ₂ ) and hydrogen (H ₂ ) are generated by the reaction of water and magnesium ions. At the same time, it becomes alkaline reduced water.
Furthermore, it becomes a mineral-rich magnesium ion water containing abundant hydrogen (H ₂ ). In addition, this alkali-reduced water suppresses the occurrence of water rot and bad odor, and the effect of brightening flowers and leaves can be obtained by cutting up the magnesium ion water by cut flowers, etc., which can prolong the life more beautifully. It becomes like this.

  In addition, by applying to any water such as tap water, well water, natural water, water having a low redox potential (alkali reduced ion water) can be produced easily and at low cost.

  Also, countless fine hydrogen bubbles are generated from magnesium (Mg), so that dust and impurities contained in the water can rise together with the countless fine bubbles to the surface of the water and can be easily removed. Become.

  Also, one of the two types of dissimilar metals, the first metal 1 is formed so that the opening distance between the wires is substantially the same as the diameter of the wire, and one end surface is formed by bending the end of the wire inward. The bottom metal springs 11, 12 a are closed to form a pair of bottomed coil springs 11, 12. The second metal 2 is the same as the inner diameter of the bottomed coil springs 11, 12 constituting the first metal 1. Since it is composed of a round bar 21 having a diameter or an outer diameter larger than that, both ends of the second metal 2 in the shape of a round bar are inserted into the two bottomed coil springs 11, 12. Two kinds of dissimilar metals having different ionization tendency and / or electric potential are obtained by screwing and integrating the end portions of the wire rods on the open end side of the bottom coil springs 11 and 12 along the opening distance between the mating wires. (First metal 1 and first metal It is possible to easily assemble the metal 2 and) the state of being in close contact with each other.

  In addition, when the round bar 21 which is the second metal 2 having the higher ionization tendency and / or the lower potential decreases due to the elution of magnesium ions, the screwed state of the two bottomed coil springs 11 and 12 is released. By exchanging only the reduced round bar 21 with a new one, the first metal 1 having a smaller ionization tendency and / or a higher potential that does not decrease can be reused by a simple replacement operation.

  Therefore, it is possible to easily assemble two kinds of dissimilar metals in close contact with each other without requiring special equipment, thereby reducing the manufacturing cost and reusing one of the first metals 1. The effect that it can be utilized and a running cost can be reduced is acquired.

  Further, by forming the round bar 21 which is the second metal 2 to have an outer diameter larger than the inner diameter of the bottomed coil springs 11 and 12 which are the first metal 1, the one having a higher ionization tendency and / or a lower potential. Even if the second metal 2 is reduced, two kinds of different metals can be kept in close contact with each other, whereby the elution period of metal ions (magnesium ions) can be lengthened.

  Furthermore, even if the round bar 21 which is the second metal 2 having the higher ionization tendency and / or the lower potential is reduced, the two members are separated and scattered by the bottom members 11a and 12a of the bottomed coil springs 11 and 12. In addition, it is possible to maintain a close contact state between two different kinds of metals, though partially.

  Further, since the bottom members 11a and 12a are constituted by the end portions of the wire constituting the bottomed coil springs 11 and 12, there is no need to manufacture the bottom members 11a and 12a separately, thereby reducing the manufacturing cost. Can be reduced.
