An ion adsorbing unit 3 that captures a part of ions generated in the vicinity of the first electrode unit 1 by being applied is provided.

  The first electrode portion 1 has a long and substantially cylindrical shape, one end of which is fixed to the electrode holder 4 and is connected to the voltage applying means 6 via the lead wire 5. Here, the 1st electrode part 1 consists of metals, and transition metals, such as gold | metal | money, nickel, platinum, rhodium, palladium, silver, copper, and zinc are used as this metal. Since gold or platinum has an antioxidant action, if gold or platinum is used as the first electrode part 1, fine gold or platinum is released from the first electrode part 1, and the antioxidant action by the fine particles is expected. can do. Similarly, if silver or copper is used for the first electrode portion 1, an antibacterial effect can be expected. In addition, since zinc is an essential element of the living body, when zinc is used as the first electrode portion 1 and the finely divided zinc is allowed to act on the hair, it acts on the hair cuticle to obtain an effect of preventing split hairs and acts on the scalp. Hair growth effect is obtained. Further, the first electrode portion 1 may not be composed of a single metal, but may be composed of two or more kinds of metals by plating, an alloy, or the like, so that the effects of the respective metals described above can be achieved simultaneously.

  The second electrode portion 2 is made of a conductor and is connected to the ground via a lead wire 5. Here, the conductor is, for example, a metal or conductive resin having a relatively low surface resistivity. The second electrode portion 2 has a flat plate shape, and a substantially circular opening is formed at a substantially central portion of the flat plate. The diameter of the opening is formed so as to be larger than the diameter of the circle appearing on the two surfaces at both ends of the elongated first electrode portion 1. As for the 2nd electrode part 2, a flat plate surface is orthogonal to the longitudinal direction of the 1st electrode part 1, and also a flat surface is a fixed distance from the tip of the 1st electrode part 1 on the opposite side to the electrode holder 4 side. They are arranged so as to face each other and are fixed by the electrode holder 4. At this time, the opening of the second electrode portion 2 is located in front of the first electrode portion 1 in the longitudinal direction, and the finely divided metal discharged from the first electrode portion 1 is the second electrode portion. 2 is configured to pass through the opening formed in 2.

  The ion adsorption part 3 is comprised with a pair of flat conductor. Here, the conductor is, for example, a metal or conductive resin having a relatively low surface resistivity.

Therefore, according to the metal fine particle production | generation apparatus K of this embodiment, since the ion adsorption | suction part 3 was provided, it can capture | acquire some ions and can control the quantity of ion. Moreover, since the ion adsorption part 3 is arrange | positioned in the front side from which the metal atomized from the 1st electrode part 1 is discharge | released, ie, the opposite side of the 1st electrode part 1 in the 2nd electrode part 2, Ions can be captured by the ion adsorbing unit 3 on the front side from which fine metal is released.

  In the above-described embodiment, a pair of flat conductors are arranged as the ion adsorbing unit 3. However, the ion adsorbing unit 3 is surrounded by the first electrode unit 1 so as to surround the front where fine metal is released. It may be arranged. In other words, a plurality of flat conductors may be arranged so as to surround the front of the first electrode portion 1, and the ion adsorbing portion 3 is cylindrical as shown in FIGS. It may be formed so as to surround the front of the first electrode portion 1. Thus, by arranging the ion adsorbing part 3 so as to surround the front of the first electrode part 1, ions generated radially from the first electrode part 1 to the front are reduced in the area of the ion adsorbing part 3. It is possible to capture more efficiently by increasing.

In the metal fine particle generation device K of the present embodiment, the ion adsorption unit 3 is connected to the ground via the lead wire 5.

  Therefore, since the electric charge due to the ions captured by the ion adsorbing unit 3 is released to the ground, it is possible to prevent the ion adsorbing unit 3 from being charged by the captured ions and lowering the ion capturing efficiency by the ion adsorbing unit 3. .

  Next, a third embodiment will be described based on FIG. In addition, about the structure similar to the metal microparticle production | generation apparatus K of 1st embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted. The ion adsorbing part 3 of the present embodiment is constituted by a pair of third electrode parts 3a and 3b, one third electrode part 3a being connected to the ground via a lead wire 5, and the other third electrode part. 3 b is connected to a voltage applying means 7 for applying a voltage via a lead wire 5. In this case, when a voltage is applied to the third electrode portion 3b by the voltage applying means 7 and a potential difference is generated between the pair of third electrode portions 3a and 3b, an electric field is generated between the third electrode portions 3a and 3b. Thus, the ions can be more efficiently captured by the third electrodes 3a and 3b which are the ion adsorbing portions 3 by attracting the ions.

And a voltage control unit 23 that varies the voltage of the voltage applying means 7.

  In this embodiment, when ions generated in the vicinity of the first electrode portion 1 are captured by the third electrode portions 3a and 3b, the ions are charged by the ions captured by the third electrode portions 3a and 3b. A current flows through the lead wire 5 connected to the third electrode portions 3a and 3b, and this current is detected by the current detection means 20 as a measured current value. At this time, if the amount of ions trapped by the third electrode portions 3a and 3b is small, the measured current value measured by the current detecting means 20 decreases, and the controller 21 determines that the decreased measured current value is the set current value. The voltage applied to the voltage applying means 7 is increased so that more ions are captured, and the measured current value matches the set current value. On the other hand, if the amount of ions captured by the third electrode portions 3a and 3b is large, the measured current value measured by the current detection means 20 increases, and the controller 21 determines that the increased measured current value is the set current value. The voltage applied to the voltage applying means 7 is lowered so that the measured current value matches the set current value. Therefore, the control unit 21 controls the voltage applying unit 7 so that the measured current value becomes a preset set current value, so that the third electrode units 3a and 3b can control the voltage application unit 7 according to the amount of ions generated.

And a voltage control unit 33 that varies the voltage applying means 7 so that the amount is constant.

  In the metal fine particle generating apparatus K of the present embodiment, when the measured ion amount measured by the ion detecting unit 30 is larger than the set ion amount, the control unit 31 increases the voltage applied to the voltage applying unit 7 to increase the voltage. Ions are captured to match the measured ion amount with the set ion amount. On the other hand, when the measured ion amount measured by the ion detection means 30 is smaller than the set ion amount, the control unit 31 lowers the voltage applied to the voltage application means 7 to reduce the ion trapping amount and the measured ion amount.
