Embodiments for Carrying Out the Invention

[0007] FIG. 1 is a perspective view schematically showing the appearance of a beauty device according to an embodiment. The beauty device 1 of this embodiment is for giving a beauty treatment to a human body, and includes a head portion 10, a handle portion 12, a treatment surface 14, four electromagnetic units 16, and an operation portion 18. The user can hold the handle portion 12 of the beauty device 1 by hand and operate the beauty device 1 so that each electromagnetic unit 16 on the treatment surface 14 in the head portion 10 contacts the skin of a desired position on the body, thereby receiving a beauty treatment for the human body. The part where each electromagnetic unit 16 is contacted may be the skin of the face or the skin of other parts of the body. Note that the beauty device 1 incorporates a rechargeable battery (not shown), operates by receiving power supply from this battery, and also operates when an AC adapter (not shown) is connected.

[0008] The beauty treatments that can be given by the beauty device 1 of this embodiment are treatments by electrical signals and treatments by magnetism. Treatments by electrical signals include, for example, applying a high-frequency current in the frequency band of radio waves (RF waves) to the skin and applying an electrical stimulus to muscles (so-called EMS; Electrical Muscle Stimulation). Also, treatments by magnetism include obtaining effects such as improving blood flow by passing magnetic field lines from the skin into the body. Hereinafter, the configuration for realizing these beauty treatments will be described in detail.

[0009] FIG. 2 is a plan view showing the arrangement of each electromagnetic unit in the head portion. Here, in order to distinguish each electromagnetic unit 16, the electromagnetic units 16a to 16d are given different symbols. As shown in the figure, the electromagnetic units 16a to 16d are arranged so as to surround the approximate center of the treatment surface 14. The distances between the electromagnetic unit 16a and the electromagnetic unit 16d, between the electromagnetic unit 16b and the electromagnetic unit 16c, between the electromagnetic unit 16a and the electromagnetic unit 16c, and between the electromagnetic unit 16b and the electromagnetic unit 16d are set to be approximately the same, for example. Also, the diameter of each electromagnetic unit 16a etc. in plan view can be, for example, about 20 mm.

[0010] In the present embodiment, the electromagnetic unit 16a and the electromagnetic unit 16b form a pair, and the electromagnetic unit 16c and the electromagnetic unit 16d form a pair, and they are respectively used for electrical signals and magnetic treatments. Here, two pairs (four) of electromagnetic units 16a to 16d are shown, but at least one pair (two) of electromagnetic units is sufficient, and on the other hand, three or more pairs of electromagnetic units may be provided. Also, the arrangement of each electromagnetic unit 16a etc. on the treatment surface 14 is not limited to that shown in the figure.

[0011] FIG. 3 is a cross-sectional view for explaining the electromagnetic unit and the structure around it. Here, the structure of the electromagnetic unit 16a and its surroundings is shown, but the structure is common also in the other electromagnetic units 16b to 16d and their surroundings. Hereinafter, the structure of the electromagnetic unit 16a and its surroundings will be described as a representative.

[0012] The electromagnetic unit 16a has a contacted part 20a which is at least partially exposed outside the treatment surface 14 (i.e., outside the head part 14) and is configured to be able to contact the human body, a core part 20b which is integrally formed with the contacted part 20a and is arranged inside the treatment surface 14 (i.e., inside the head part 14), and a coil 22 spirally arranged around the core part 20b. The contacted part 22a and the core part 20b of the electromagnetic unit 16a are made of a material that can conduct current and can be magnetized by energizing the coil 22 arranged around the core part 20b. As an example, a material with iron plating can be used as the material. By passing a current between the electromagnetic unit 16a and another electromagnetic unit (the electromagnetic unit 16b in this example), treatment of the human body with an electrical signal can be performed.

[0013] The coil 22 is made of a material that can conduct current. For example, a copper wire can be used as the material. In this embodiment, an electromagnet is formed by the coil 22 and the core part 20b. By energizing the coil 22, the core part 20b can be magnetized, and a magnetic flux (magnetic field) passing through the core part 20b can be generated. Magnetic treatment is realized using this magnetic flux.

[0014] The shielding part 24 is arranged around the core part 20b and the coil 22 so as to surround them inside the treatment surface 14. This shielding part 24 is for shielding the magnetic flux generated by the electromagnet formed by the core part 20b and the coil 22. By having the shielding part 24, the magnetic flux can be concentrated more efficiently around the electromagnetic unit 16a.

[0015] The bottom part 26 is for closing the lower part of the shielding part 24 and has a through hole 28. The through hole 28 is for passing wiring for connecting to the electromagnetic unit 16a and wiring for connecting to the coil 22.

[0016] FIG. 4 is a diagram for explaining the circuit configuration of the beauty device according to the present embodiment. As shown in the figure, the beauty device 1 includes electromagnetic units 16a and 16b, an operation unit 18, a magnetic generation circuit (first circuit) 30, an electrical signal generation circuit (second circuit) 32, and a control unit 34. Here, a pair of the electromagnetic unit 16a and the electromagnetic unit 16b is shown, but pairs of other electromagnetic units 16c and 16d are similarly connected to the magnetic generation circuit 30 and the electrical signal generation circuit 32.

[0017] The magnetic generation circuit 30 is a circuit for outputting a current to the coils 22 of the electromagnetic units 16a and 16b. When a current is passed through each coil 22 by this magnetic generation circuit 30, each iron core portion 20b disposed inside each coil 22 is magnetized, and a magnetic flux passing through the coil 22 is generated. By this magnetic flux, treatment using magnetism can be performed on the human body. As the current flowing through each coil 22, for example, an alternating current of about 10 Hz can be used, but a direct current may also be used.

[0018] In the present embodiment, the coil 22 of the electromagnetic unit 16a and the coil 22 of the electromagnetic unit 16b are connected in series, and both ends of the series connection of these coils 22 and the magnetic generation circuit 30 are connected. Thereby, simplification of the circuit configuration is achieved. Note that each of the coil 22 of the electromagnetic unit 16a and the coil 22 of the electromagnetic unit 16b may be separately connected to the magnetic generation circuit 30 and separately supplied with current.

[0019] The electrical signal generation circuit 32 is connected to the electromagnetic units 16a and 16b, and outputs a current for performing treatment by an electrical signal. As shown in the figure, in each of the electromagnetic units 16a and 16b, when a portion exposed outside the treatment surface 14 of the contacted portion 20a contacts the human skin, the human body is used as a current path 36, and a current can flow between the contacted portions 20a of the electromagnetic units 16a and 16b, and treatment by an electrical signal is realized.

[0020] When applying a high-frequency current in the frequency band of radio waves (RF waves) as an electrical signal to the skin, for example, an alternating current of about 1 MHz can be used. Also, when applying an electrical stimulus to muscles (so-called EMS), for example, an alternating current of about 5 to 100 Hz can be used.

[0021] The control unit 34 controls the overall operation of the beauty device 1, and is realized by using, for example, a microcomputer equipped with a CPU, ROM, RAM, etc., and causing this microcomputer to execute a predetermined operation program. Specifically, the control unit 34 controls the operations of the magnetic generation circuit 30 and the electrical signal generation circuit 32 in response to an operation instruction by the user using the operation unit 18. Further, the control unit 34 controls the lighting state of an indicator (not shown) such as a lamp appropriately provided in the handle unit 12 or the like. Thereby, the user can be notified of the current operation mode.

[0022] According to the above-described embodiment, since an electromagnetic unit in which a contact portion for treatment by an electrical signal and a core constituting an electromagnet for treatment by magnetism are integrally configured is used, it is possible to provide a beauty device capable of performing a plurality of beauty treatments with a simple configuration.

[0023] Note that the present invention is not limited to the content of the above-described embodiment, and various modifications can be made and implemented within the scope of the gist of the present invention. For example, the overall external shape of the beauty device shown in FIG. 1 and the shape of each electromagnetic unit are merely examples and are not limited thereto.

[0024] Also, the circuit configuration shown in FIG. 4 is just an example, and it does not exclude the addition of other circuit elements. That is, in this specification, when it is expressed that circuit elements are "connected" to each other, in addition to the case where those circuit elements are directly connected via wiring or the like, it also includes the case where other circuit elements are interposed between the circuit elements. The circuit elements referred to here may be anything that can exhibit an electrical function, and include, for example, passive elements such as resistor elements and capacitor elements, and active elements such as transistors.
