  • the electrode that is in contact with the liquid on the side facing the sliding surface 57 a cathode that easily emits microparticles, many microparticles can be released into the liquid.
  • the fine particles of the electrode can be adhered to the sliding surface 57 while cleaning the electric razor (hair removal device) 50, and the cleaning effect of the electric razor (hair removal device) 50 by the liquid cleaning can be improved.

  • the first electrode 12 and the second electrode 13 are the blade portions (sliding portion). It is made of a material having a lower coefficient of friction than the material forming the 54 sliding surfaces 57. Therefore, the contact state of the sliding portion 57 (contact state between the outer surface 55a of the inner blade 55 and the inner surface 56a of the outer blade 56) in the micro environment is due to the electrode material and the sliding portion material or due to the electrode materials. Thus, seizure of the blade portion (sliding portion) 54 can be further suppressed as compared with the initial cleaning state.
  • the first electrode 12 and the second electrode 13 includes at least one of Sn and Sn compounds. If formed of a material, Sn or Sn compound adheres to the sliding surface 57. Since this Sn has a characteristic that the friction coefficient is lower than that of a general metal, it becomes possible to reduce the friction generated when the blade portion (sliding portion) 54 slides, and the blade portion (sliding portion) 54. It becomes possible to further suppress the seizure of the material.
  • the first electrode 12 and the second electrode 13 (of the first electrode and the second electrode, at least the electrode facing the sliding surface of the sliding portion) include at least one of Ti and a Ti compound. If formed of a material, Ti or a Ti compound adheres to the sliding surface 57. This Ti also has a feature that the coefficient of friction is lower than that of general metals. Furthermore, Ti is a material that is relatively safe for the user's skin because it has a higher physiological affinity than general metals. Thus, if it forms with the material containing at least any one among Ti and Ti compound, it can suppress the seizing of the blade part (sliding part) 54, ensuring the safety

If formed of a material, carbon or a carbon compound adheres to the sliding surface 57. This carbon is also characterized by a lower coefficient of friction than ordinary metals. Furthermore, since carbon has a feature of higher hardness than general metals, the effect of suppressing seizure of the blade portion (sliding portion) 54 can be further maintained.

Abstract

L'invention porte sur un dispositif de nettoyage (40), lequel dispositif comporte un dispositif de génération de plasma (1). Le dispositif de génération de plasma (1) comporte : une section de stockage de liquide (4) pour stocker un liquide contenant de l'eau ; une section de stockage de gaz (5) pour stocker un gaz ; une séparation (3) qui sépare la section de stockage de liquide (4) vis-à-vis de la section de stockage de gaz (5), et dans laquelle un trajet de gaz (3a) qui conduit un gaz dans la section de stockage de gaz (5) vers la section de stockage de liquide (4) est formé ; une première électrode (12) disposée dans la section de stockage de gaz (5) ; et une seconde électrode (13) disposée de telle sorte qu'au moins la partie qui forme une paire avec la première électrode (12) est en contact avec le liquide (17) dans la section de stockage de liquide (4). Le dispositif de nettoyage est configuré de telle sorte que, quand un appareil de retrait de poil (50) est monté, la surface de coulissement (56) de la section de coulissement (54) fait face au voisinage d'au moins l'une ou l'autre de la première électrode (12) ou de la seconde électrode (13) sans obstruction.
