Abstract

A beauty tool ( 1 ) includes: a substantially rod-shaped main body ( 10 ); an attraction head ( 2 ) provided in the main body ( 10 ); and a beauty effect imparting part for imparting a beauty effect to human skin in a state where it is in contact with or close to the human skin. The attraction head ( 2 ) is provided at one end of the main body ( 10 ) and includes a magnetic force generating surface ( 20 ) for attracting and removing, by means of a magnetic force, a cosmetic agent applied to the human skin.

First claim

What is claimed is:

1. A beauty tool, comprising:
a substantially rod-shaped main body;
an attraction head provided at one elongate end of the main body, and including a magnetic force generating surface to attract and remove a cosmetic agent applied to human skin using magnetic force, a permanent magnet embedded within the attraction head; and
a beauty effect imparting part provided at the other elongate end of the main body, to impart a beauty effect to the human skin in a state where the beauty effect imparting part is in contact with or close to the human skin, the beauty effect imparting part including a working electrode.

2. The beauty tool according to claim 1 , wherein the attraction head includes the magnetic force generating surface facing in a direction substantially perpendicular to a longitudinal direction of the main body.

3. The beauty tool according to claim 1 , wherein
the beauty effect imparting part comprises a working electrode that causes an ion introduction current to flow to a contact part when in contact with the human skin, and
the main body includes a power supply to supply power to the working electrode and a controller to control the current flowing to the contact part.

4. The beauty tool according to claim 3 , wherein
the main body comprises, a counter electrode on a side opposed to the magnetic force generating surface, the counter electrode is configured to be able to form a closed current path passing through the power supply and a human body together with the working electrode, and
the working electrode is disposed so as to face a side the magnetic force generating surface faces.

5. The beauty tool according to claim 3 , wherein
the controller includes circuitry configured to:
apply a pulse voltage to the working electrode, and measure an electrical characteristic value in the controller;
determine whether or not the working electrode is in contact with the human body, based on the electrical characteristic value; and
cause the ion introduction current to flow to the contact part when it is determined that the working electrode is in contact with the human body, and

the controller is configured to, when it is determined that the working electrode is not in contact with the human body, perform a measurement of the electrical characteristic value and the determination again after waiting for a lapse of a predetermined time by using a delay timer.

6. The beauty tool according to claim 5 , wherein the controller:
includes a reflux section that takes in the current flowing through the human body, and refluxes the current to the power supply,
measures a potential difference of the reflux section with respect to a ground potential, as the electrical characteristic value, and
determines that the working electrode is in contact with the human body when the potential difference is equal to or larger than a predetermined threshold.

7. The beauty tool according to claim 3 , wherein the ion introduction current allows the following to be successively repeated: causing a current of a first polarity to flow to the contact part; causing a pulse current of a second polarity to flow to the contact part; and causing a current whose polarities alternately change to flow to the contact part.

8. A beauty tool, comprising:
a substantially rod-shaped main body;
an attraction head provided at one elongate end of the main body, and including a magnetic force generating surface to attract and remove a cosmetic agent applied to human skin using magnetic force, an electromagnet embedded within the attraction head; and
a beauty effect imparting part provided at the other elongate end of the main body, to impart a beauty effect to the human skin in a state where the beauty effect imparting part is in contact with or close to the human skin, the beauty effect imparting part including a working electrode.

9. The beauty tool according to claim 8 , wherein the attraction head includes the magnetic force generating surface facing in a direction substantially perpendicular to a longitudinal direction of the main body.

10. The beauty tool according to claim 8 , wherein the beauty effect imparting part comprises a working electrode that causes an ion introduction current to flow to a contact part when in contact with the human skin, and
the main body includes a power supply to supply power to the working electrode and a controller to control the current flowing to the contact part.

11. The beauty tool according to claim 10 , wherein
the main body comprises, a counter electrode on a side opposed to the magnetic force generating surface, the counter electrode is configured to be able to form a closed current path passing through the power supply and a human body together with the working electrode, and
the working electrode is disposed so as to face a side the magnetic force generating surface faces.

12. The beauty tool according to claim 10 , wherein
the controller includes circuitry configured to:
apply a pulse voltage to the working electrode, and measure an electrical characteristic value in the controller;
determine whether or not the working electrode is in contact with the human body, based on the electrical characteristic value; and
cause the ion introduction current to flow to the contact part when it is determined that the working electrode is in contact with the human body, and

the controller is configured to, when it is determined that the working electrode is not in contact with the human body, perform a measurement of the electrical characteristic value and the determination again after waiting for a lapse of a predetermined time by using a delay timer.

13. The beauty tool according to claim 12 , wherein the controller:
includes a reflux section that takes in the current flowing through the human body, and refluxes the current to the power supply,
measures a potential difference of the reflux section with respect to a ground potential, as the electrical characteristic value, and
determines that the working electrode is in contact with the human body when the potential difference is equal to or larger than a predetermined threshold.

14. The beauty tool according to claim 10 , wherein the ion introduction current allows the following to be successively repeated: causing a current of a first polarity to flow to the contact part; causing a pulse current of a second polarity to flow to the contact part; and causing a current whose polarities alternately change to flow to the contact part.
