Japanese Laid-Open Patent Publication No. 2008-23063 discloses a hair dryer that discharges fine particles of the transition metal by discharging the electrodes including the transition metal, and discharges the fine particles toward the hair. In the hair dryer, the tip end of the rod-shaped discharge electrode is sharpened.

In the metal microparticle generating device used in such a hair care device, if it is used for a long period of time, since the fine particles of the metal are discharged from the front end portion of the electrode tip, the front end portion may become dull.

In this case, the concentration of the electric field on the electrode becomes low, which may lower the ability to generate metal fine particles.

Accordingly, an object of the present invention is to provide a metal fine particle generating device and a hair care device comprising the same, which can prevent the generation ability of metal fine particles from decreasing with time.

An aspect of the present invention is a metal fine particle generating apparatus comprising a discharge electrode and a ground electrode, and a metal fine particle generating device that discharges fine particles of metal contained in the metal member by discharging between the discharge electrode and the ground electrode. At least one of the above-described discharge electrode and ground electrode is formed by a wire.

Composition. When the fine particles of the metal generated by the metal fine particle generation device 1 contain gold, silver, or copper, the antibacterial action can be generated by the fine particles of the metal. In the case where the fine particles of the metal contain platinum, zinc, titanium or the like, the antibacterial action can be produced by the fine particles of the metal. The platinum microparticles have a very high antioxidant effect. The metal microparticle generation device 1 generates ions (for example, negative ions such as NO ₂ ^- , NO ₃ ^-, etc.) by discharge, and causes the ions to collide with the discharge electrode 2, the ground electrode 3, other metal materials, or a member containing a metal component. Etc., it is also possible to produce metal particles.

On the substrate 4, the second member 7 is placed in an overlapping manner. At this time, the posture of the substrate 4 is such that the surface 4s on which the discharge electrode 2 composed of the wire material is placed faces the bottom wall portion 6i side, and a gap is formed between the surface 4s and the bottom wall portion 6i. As shown in Fig. 6, the discharge electrode 2 is disposed along the center line C of the opening 3c.

As described above, in the metal fine particle generator 1 of the present embodiment, the discharge electrode is formed by a wire. Since the thickness of the wire is generally substantially constant in the longitudinal direction, even if the tip disappears due to discharge and the length is shortened, it is easy to maintain the radius of curvature of the tip end at a substantially constant value in accordance with the thickness of the wire. Therefore, by forming the discharge electrode 2 with a very thin wire, even if the tip end becomes dull, it is easy to maintain a small radius of curvature, and it is easy to maintain the concentration of the electric field in a strong state, and the ability to prevent generation of metal particles can be prevented from being lowered. .

[Industrial availability]

According to the invention, at least one of the discharge electrode and the ground electrode is formed by a wire. The thickness of the wire is approximately constant in the length direction, so even if the front end becomes dull due to discharge, it is easy to keep the radius of curvature small, thereby maintaining the concentration of the electric field in a strong state, and preventing generation of metal particles. The ability to reduce. Thus, according to the present invention, it is possible to manufacture a metal fine particle generating device and a hair care device comprising the same, which can prevent the generation ability of metal fine particles from decreasing with time.
