DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the following description, the same components are denoted by the same reference numerals. The names and functions of the components are also the same. Therefore, detailed descriptions thereof will not be repeated.

[0010] The configuration of a beauty device 1 according to one embodiment of the present invention will be described below.

[0011] <1. Overview> First, an overview of the beauty device 1 will be described with reference to Fig. 1. As shown in Fig. 1, the beauty device 1 is a device for performing beauty treatments on customers. The beauty device 1 is used, for example, in a beauty salon by a store staff member who is a practitioner U. The beauty device 1 performs various beauty treatments, which will be described later, on a patient C who is a customer of the beauty salon.

[0012] Fig. 1 is a diagram showing the overall configuration of a beauty device 1. As shown in Fig. 1, the beauty device 1 includes a control box 10 and a plurality of external terminals. The external terminals include a pair of RF probes 30, a pair of ultrasonic probes 60, and an earth plate 40.

[0013] When the beauty device 1 uses a pair of RF probes 30 and an earth plate 40, it performs a beauty treatment on a subject C by dielectrically heating the human body. In the following description, such a beauty treatment using dielectric heating is referred to as a radio frequency treatment (high frequency treatment).

[0014] Furthermore, when the beauty device 1 uses a pair of ultrasonic probes 60, it can perform a beauty treatment on the person C by applying ultrasonic vibrations to the human body. Such beauty treatments using ultrasonic vibrations will be referred to as ultrasonic treatments and cavitation treatments in the following description. The difference between ultrasonic treatments and cavitation treatments will be described later.

[0015] Furthermore, the beauty device 1 can perform EMS and iontophoresis treatments using a pair of ultrasonic probes 60 connected to the control box 10 and an output pad 80 (see FIG. 2) connected to the control box 10. The specific details of each of these treatments will be described later.

[0016] The control box 10 is housed inside the housing and is a control panel that controls the beauty device 1. A practitioner U, who is a staff member of the beauty salon, performs a beauty treatment on a customer (a person C) of the beauty salon using an external terminal while configuring the operation settings of the control box 10. The configuration of such beauty device 1 will be described below.

[0017] <2. Configuration of beauty device 1> Next, the configuration of the beauty device 1 will be described with reference to FIGS.

[0018] (1) Control Box 10 First, the configuration of the control box 10 will be described with reference to Fig. 2. Fig. 2 is a diagram showing the hardware configuration of the beauty device 1 shown in Fig. 1. As shown in Fig. 2, the control box 10 contains a main control circuit 11, a power supply circuit 12, a wireless module 13, an operation switch 14, a display panel 15, a first oscillation circuit 20, a second oscillation circuit 50, and a third oscillation circuit 70.

[0019] The main control circuit 11 is a control circuit that generates and controls control commands to the wireless module 13, the display panel 15, the first oscillation circuit 20, the second oscillation circuit 50, and the third oscillation circuit 70 in response to input operations from a user. The main control circuit 11 is, for example, a microcomputer. The main control circuit 11 functions as a processor, a memory, and a communication IF.

[0020] A processor is hardware for executing an instruction set written in a program stored in a memory, and is composed of an arithmetic unit, registers, peripheral circuits, and the like.

[0021] The memory is configured by a memory circuit and is a storage device for storing control commands corresponding to the operation patterns of each module. Instead of a memory circuit, the main control unit may have a volatile memory such as a DRAM (Dynamic Random Access Memory), a flash memory, or an HDD (Hard Disc Drive).

[0022] The communication IF is an interface for inputting and outputting signals so that the cosmetic device 1 can communicate with external devices.

[0023] The power supply circuit 12 supplies the necessary DC current to each module included in the control box 10 based on the power output from the AC adapter.

[0024] The wireless module 13 performs wireless communication with an external device in response to a control command from the main control circuit 11. The wireless module 13 performs wireless communication with a communication device such as a wireless base station conforming to a communication standard such as 5G or LTE (Long Term Evolution), or a wireless LAN (Local Area Network) router conforming to a wireless LAN standard such as IEEE (Institute of Electrical and Electronics Engineers) 802.11.

[0025] The operation switch 14 is an input device that accepts input operations from the user, and may be a pointing device such as a touchpad or a mouse, or another input device such as a keyboard.

[0026] The display panel 15 is a display device that displays information related to the control of the beauty device 1. For example, a liquid crystal display is used for the display panel 15. The display panel 15 displays various information in response to a liquid crystal control signal input from the main control circuit 11.

[0027] (2) Oscillator circuit Next, the configuration of the oscillation circuit will be described. The beauty device 1 is equipped with three types of oscillation circuits. As shown in Fig. 2, the control box 10 is equipped with a first oscillation circuit 20, a second oscillation circuit 50, and a third oscillation circuit 70. These will be described below.

[0028] (2-1) First Oscillator Circuit 20 The first oscillator circuit 20 is a circuit that generates a high-frequency voltage based on a power control signal input from the main control circuit 11. The first oscillator circuit 20 includes a power supply circuit. The first oscillator circuit 20 is a CR oscillator circuit having a capacitor and a resistor. In this case, the first oscillator circuit 20 generates a high-frequency voltage by charging and discharging a voltage to the capacitor. The first oscillator circuit 20 may also be an LC circuit having a coil and a capacitor. In this case, the first oscillator circuit 20 generates a high-frequency voltage by vibrating while exchanging energy between the coil and the capacitor. The first oscillator circuit 20 generates a high-frequency voltage of, for example, 300 kHz. The frequency of the voltage generated by the first oscillator circuit can be set arbitrarily.

[0029] A pair of RF probes 30, which are external terminals, and an earth plate 40 are connected to the first oscillation circuit 20. The first oscillation circuit 20 operates together with the RF probes 30 and the earth plate 40 to function as a high-frequency beauty device that performs radiofrequency treatment. The configurations of the RF probes 30 and the earth plate 40 will be described later.

[0030] (2-2) Second Oscillator Circuit 50 The second oscillator circuit 50 is a circuit that generates an AC signal of a predetermined frequency based on a power control signal input from the main control circuit 11. The second oscillator circuit 50 includes a power supply circuit. It is a CR oscillator circuit having a capacitor and a resistor. In this case, the second oscillator circuit 50 generates a high-frequency voltage by charging and discharging a voltage to the capacitor. The second oscillator circuit 50 may also be configured as an LC circuit having a coil and a capacitor. In this case, the second oscillator circuit 50 applies the AC signal generated in the LC circuit to a vibrator, causing the vibrator built into the ultrasonic probe 60 to vibrate.

[0031] An ultrasonic probe 60 is connected to the second oscillation circuit 50. The second oscillation circuit 50 operates together with the ultrasonic probe 60 to perform functions as an ultrasonic treatment device and an ultrasonic cosmetic device. The configuration of the ultrasonic probe 60 will be described later.

[0032] The second oscillator circuit 50 includes an ultrasonic oscillator circuit 51 and a cavitation oscillator circuit 52. The ultrasonic oscillator circuit 51 generates an AC signal of 1.5 MHz. The ultrasonic oscillator circuit 51 generates a signal used in ultrasonic treatment. The cavitation oscillator circuit 52 generates an AC signal of 36 kHz. The cavitation oscillator circuit 52 generates a signal used in cavitation treatment.

[0033] The ultrasonic oscillation circuit 51 includes a first ultrasonic oscillation circuit 51 A and a second ultrasonic oscillation circuit 51 B. The first ultrasonic oscillation circuit 51 A and the second ultrasonic oscillation circuit 51 B have the same configuration.

[0034] The cavitation oscillation circuit 52 includes a first cavitation oscillation circuit 52 A and a second cavitation oscillation circuit 52 B. The first cavitation oscillation circuit 52 A and the second cavitation oscillation circuit 52 B have the same configuration.

[0035] In the second oscillation circuit 50, the first ultrasonic oscillation circuit 51A and the first cavitation oscillation circuit 52A are connected in series to form a multiple oscillation circuit. Either the output terminal of the first ultrasonic oscillation circuit 51A or the first cavitation oscillation circuit 52A is bridged by a capacitor.

[0036] Therefore, in the second oscillator circuit 50 of the present invention, by simultaneously operating the first ultrasonic oscillator circuit 51A and the first cavitation oscillator circuit 52A, it is possible to apply to the vibrator an AC signal generated from the first ultrasonic oscillator circuit 51A and an AC signal generated from the first cavitation oscillator circuit 52A in an overlapping state.

[0037] The ultrasonic waves generated by the oscillator vibrating due to the superimposed AC signals are composite waves of the ultrasonic waves generated by the AC signal generated from the first ultrasonic oscillator circuit 51A and the ultrasonic waves generated by the AC signal generated from the first cavitation oscillator circuit 52A. Note that the first ultrasonic oscillator circuit 51A and the first cavitation oscillator circuit 52A can also be operated independently.

[0038] The connection structure of the second ultrasonic oscillator circuit 51B and the second cavitation oscillator circuit 52B is also the same as that of the first ultrasonic oscillator circuit 51A and the first cavitation oscillator circuit 52A. Therefore, by simultaneously operating the second ultrasonic oscillator circuit 51B and the second cavitation oscillator circuit 52B, ultrasonic waves generated by the two oscillator circuits are synthesized and output. Note that the second ultrasonic oscillator circuit 51B and the second cavitation oscillator circuit 52B can also be operated independently.

[0039] (2-3) Third Oscillator Circuit 70 The third oscillation circuit 70 is a circuit that generates a low-frequency electrical signal based on the input of a power control signal from the main control circuit 11. The third oscillation circuit 70 generates an electrical signal used in EMS (Electrical Muscle Stimulation), which applies low-frequency electrical stimulation of several Hz to several hundred Hz to the human body.

[0040] The third oscillation circuit 70 uses a weak current to electrically ionize the beauty ingredients present on the skin and generate an electrical signal used for iontophoresis, which allows the ingredients to penetrate the skin. The third oscillation circuit 70 is equipped with a power supply circuit.

[0041] (3) External terminal Next, the configuration of the external terminals of the beauty device 1 will be described with reference to Fig. 2. As shown in Fig. 2, the beauty device 1 includes, as external terminals, an RF probe 30, an earth plate 40, an ultrasonic probe 60, and an output pad 80. The configuration of these will be described below.

[0042] (3-1) RF Probe 30 The RF probe 30 is an output terminal that radiates high-frequency electromagnetic waves to perform radiofrequency wave treatment. The RF probe 30 radiates electromagnetic waves when a high-frequency voltage generated by the first oscillation circuit 20 is applied thereto.

[0043] The RF probe 30 has a first RF probe 30A and a second RF probe 30B. When performing radiofrequency treatment, the practitioner U holds either the first RF probe 30A or the second RF probe 30B in each hand. The first RF probe 30A and the second RF probe 30B have the same configuration. The first RF probe 30A and the second RF probe 30B are connected to the first oscillation circuit 20.

[0044] The RF probe 30 has an electrode 35 (see FIG. 4B). The electrode 35 radiates electromagnetic waves when a high-frequency voltage generated by the first oscillation circuit 20 is applied. As a result, the RF probe 30 performs dielectric heating on the treatment site for radiofrequency treatment. The detailed structure of the RF probe 30 will be described later.

[0045] (3-2) Earth Plate 40 The earth plate 40 is a member that provides grounding to the electromagnetic waves radiated from the electrode 35. The earth plate 40 is made of a conductive material. When the earth plate 40 receives radiation of electromagnetic waves, it generates a current inside, thereby enabling it to properly eliminate the electromagnetic waves received by the human body. The earth plate 40 is used by being placed between the treatment subject C and the treatment table so as to come into contact with the treatment subject C.

[0046] (3-3) Ultrasonic probe 60 The ultrasonic probe 60 is an output terminal used for ultrasonic treatment and cavitation treatment. The ultrasonic probe 60 has a vibrator that vibrates when an AC signal generated by the second oscillation circuit 50 is applied. The ultrasonic probe 60 includes a first ultrasonic probe 60A and a second ultrasonic probe 60B. When performing ultrasonic treatment and cavitation treatment, the practitioner U holds either the first ultrasonic probe 60A or the second ultrasonic probe 60B in each hand.

[0047] The first ultrasonic probe 60A is connected to a first ultrasonic oscillator circuit 51A and a first cavitation oscillator circuit 52A, which are connected in series. Therefore, the vibrator of the first ultrasonic probe 60A vibrates with a composite wave of the 1.5 MHz ultrasonic waves generated by the first ultrasonic oscillator circuit 51A and the 36 kHz ultrasonic waves generated by the first cavitation oscillator circuit 52A, and stimulates the treatment area. Therefore, the first ultrasonic probe 60A can perform ultrasonic treatment and cavitation treatment simultaneously.

[0048] The second ultrasonic probe 60B is connected to a second ultrasonic oscillator circuit 51B and a second cavitation oscillator circuit 52B, which are connected in series. Therefore, the vibrator of the second ultrasonic probe 60B vibrates with a composite wave of the 1.5 MHz ultrasonic waves generated by the second ultrasonic oscillator circuit 51B and the 36 kHz ultrasonic waves generated by the second cavitation oscillator circuit 52B, and stimulates the treatment area. Therefore, the second ultrasonic probe 60B can perform ultrasonic treatment and cavitation treatment simultaneously.

[0049] (3-4) Output Pad 80 The output pad 80 is an output terminal used in EMS and iontophoresis. The output pad 80 is made of a conductive material. The output pad 80 is connected to the third oscillation circuit 70. In EMS, a current flows through the output pad 80, transmitting electrical stimulation to the muscles. On the other hand, in iontophoresis, a current flows through the output pad 80, effectively ionizing and penetrating beauty ingredients present in the skin. The current supplied to the output pad 80 is also output to the ultrasound probe 60 via wiring within the control box 10.

[0050] 3. Detailed structure of the RF probe 30 Next, the detailed structure of the RF probe 30 will be described with reference to Figures 3 and 4. Figure 3A is a side view of the RF probe 30. Figure 3B is a perspective view of the probe head 32 of the RF probe 30. As shown in Figure 3A, the RF probe 30 has a probe main body 31 and a probe head 32.

[0051] (1) Probe body 31 The probe body 31 is a member that is held by the practitioner U. The probe body 31 is made of an insulating synthetic resin material. The probe body 31 is formed with a gripping portion (not shown) that is held by the practitioner U.

[0052] The probe head 32 is a member connected to the lower part of the probe body 31. As shown in FIG. 3B, the probe head 32 has a cylindrical shape with a bottom. The probe head 32 is made of a synthetic resin material. A bottom part 32B of the probe head 32 is brought into contact with the treatment site of the patient C by operation of the practitioner U.

[0053] A cable 34 is inserted inside the probe head 32. A flange 32A that protrudes radially outward is formed at the upper end of the probe head 32. The flange 32A engages with the inside of the probe main body 31, thereby connecting the probe main body 31 and the probe head 32. The probe head 32 is attached to the probe main body 31.

[0054] (2) Probe head 32 Fig. 4A is a plan view of the probe head 32. Fig. 4B is a cross-sectional view of the probe head 32 taken along line IVB. As shown in Fig. 4A, an electrode substrate 33 is built into the bottom 32B of the probe head 32. As shown in Fig. 4B, the electrode substrate 33 is embedded in a resin mold 32C with a cable 34 connected thereto.

[0055] (3) Electrode substrate 33 4B, the electrode substrate 33 is placed on the bottom 32B of the probe head 32 and is fixed in place by a resin mold 32C while being insulated from the bottom. The electrode substrate 33 has a substrate body 36 and an electrode 35. The substrate body 36 has an annular shape with an open center in the radial direction. The electrode 35 is placed on the back surface of the substrate body 36.

[0056] The substrate body 36 has a two-layer structure including a glass layer 36A and a resin layer 36B. The glass layer 36A forms the surface of the substrate body 36 and has an annular shape. The resin layer 36B forms the bottom surface of the substrate body 36. The resin layer 36B bonds the electrode 35 to the back surface of the glass layer 36A.

[0057] In this way, since the surface of the substrate body 36 is made of glass layer 36A, heat generated from the electrode 35 laid on the back surface of the substrate body 36 can be prevented from escaping from the surface of the substrate body 36 to the inside of the probe head 32.

[0058] The electrode 35 is made of copper foil and is bonded to the glass layer 36A by the resin layer 36B. The electrode 35 is in contact with the upper surface of the bottom 32B of the probe head 32. With the electrode substrate 33 placed on the bottom 32B of the probe head 32, a molding resin is filled into the bottom 32B of the probe head 32, thereby fixing the electrode substrate 33 to the bottom 32B of the probe head 32.

[0059] Next, the shape of the electrode 35 will be described with reference to FIGS. 5 and 6. FIG. 5 is a bottom view of the electrode substrate 33. As shown in FIG. 5, the electrode 35 extends radially along the radial direction in an area on the back surface of the substrate main body 36, excluding the central area in the radial direction. In the example shown, four linear portions extending radially are formed. Because the electrode 35 extends radially in this way, the area in the bottom portion 32B of the RF probe 30 from which electromagnetic waves are generated can be made uniform throughout the entire radial area.

[0060] The electrode 35 further extends in a circular ring shape along the circumferential direction on the rear surface of the substrate body 36, in an area excluding the radial center. In the illustrated example, three circular rings with different diameters are arranged coaxially. Because the electrode 35 extends in a circular ring shape in this manner, the area in the bottom portion 32B of the RF probe 30 from which electromagnetic waves are generated can be made uniform throughout the circumferential direction. Note that in FIGS. 5 and 6, the electrode 35 extends in a circular ring shape along the circumferential direction in an area excluding the radial center, but the electrode 35 may also be arranged in the radial center. However, by not arranging the electrode 35 in the radial center, molding using a mold can be facilitated.

[0061] Furthermore, since the electrode 35 is composed of multiple linear portions and multiple annular portions, it is possible to reduce the local area of the electrode 35 while increasing the area of the back surface of the substrate body 36 that is occupied by the electrode 35. This makes it possible to suppress thermal diffusion and to output electromagnetic waves uniformly from a relatively wide area of the probe head 32.

[0062] The probe head 32 heats up when electromagnetic waves are output. If the area of the electrode 35 is large, the heat will be diffused to the electrode 35, making it difficult for the patient C to feel warmth. On the other hand, if the area of the electrode 35 is small, the heat generated when the electromagnetic waves are output will be concentrated rather than diffused, making it possible to raise the temperature perceived by the patient C.

[0063] 6 is a top view of the electrode substrate 33. As shown in Fig. 6, a connection portion 37, which forms part of the electrode 35 and to which the cable 34 is connected, is formed on the top surface of the electrode substrate 33. When the cable 34 is connected to the connection portion 37, the high-frequency voltage generated in the first oscillation circuit 20 is supplied to the electrode 35.

[0064] (4) Modification of electrode 35 Next, a modified example of the electrode 35 will be described with reference to Fig. 7. Fig. 7 is a bottom view of an electrode substrate 33A according to the modified example. As shown in Fig. 7, in the electrode substrate 33A according to the modified example, the radial outer end 35A of the electrode 35 has a circular shape. In the illustrated example, eight circular outer end portions 35A are arranged at equal intervals in the circumferential direction. In this way, by making the outer end portions 35A of the electrode 35 have a circular shape, electromagnetic waves can be efficiently output from the outer end portions 35A, which tend to have a weak output.

[0065] If the area of the electrode 35 is increased, the capacitance seen from the output circuit (transformer) increases. If the capacitance of the probe head 32 becomes too large, the impedance decreases with respect to the high-frequency voltage of several hundred kHz from the first oscillation circuit 20. As a result, the input current increases, the transformer load increases, and heat is generated, causing a decrease in output voltage. Furthermore, simply increasing the area of the electrode 35 requires a larger power supply. By forming the electrode 35 from the copper foil of the electrode substrates 33 and 33A, it is possible to output electromagnetic waves uniformly from the entire RF probe 30 while maintaining the capacitance value of the probe head 32.

[0066] <4.Summary> As described above, in the beauty device 1 of the present invention, the RF probe 30 has the electrode substrate 33 on which the electrode 35 is disposed. Therefore, the shape of the electrode 35 of the electrode substrate 33 can be easily changed while leaving the shape of the substrate body 36 unchanged. Therefore, by appropriately adjusting the shape of the electrode 35, the output of electromagnetic waves from the RF probe 30 can be adjusted. For example, by changing the shape of the electrode 35 in accordance with the required specifications of the RF probe 30, the area occupied by the electrode 35 on the bottom 32B of the probe head 32 can be increased while the local area of the electrode 35 can be reduced.

[0067] This allows high-power electromagnetic waves to be emitted from the RF probe 30 during cosmetic treatment from a wide area at the bottom 32B of the probe head 32. Furthermore, since the shape of the electrodes 35 to be mounted on the substrate body 36 can be given a degree of freedom, the output of the electromagnetic waves can be adjusted as desired by changing the shape of the electrodes 35 according to the required specifications of the cosmetic device 1.

[0068] Furthermore, in the beauty device 1 of the present invention, by reducing the local area of the electrode 35, high output can be obtained from the bottom 32B of the probe head 32 when emitting electromagnetic waves from the RF probe 30. In detailing this point, in conventional beauty devices, it is known that the surface area of the electrode increases when multiple probes are used, resulting in a decrease in the electromagnetic wave output from each probe. However, in the beauty device 1 of the present invention, the surface area can be reduced by changing the shape of the electrode 35 as described above.

[0069] Therefore, the beauty device 1 of the present invention includes multiple RF probes 30, but is able to prevent a decrease in output from each RF probe 30 and obtain sufficient output from each RF probe 30. Furthermore, by including multiple RF probes 30 in the beauty device 1, the working time required for beauty treatment can be significantly reduced, improving user convenience.

[0070] Furthermore, the beauty device 1 of the present invention functions as a high-frequency beauty device, an ultrasonic beauty device, an EMS beauty device, and an iontophoresis beauty device, so a wide range of treatments such as radio frequency treatment, ultrasonic treatment, cavitation treatment, EMS, and iontophoresis can be performed with a single machine.

[0071] <5. Other Modifications> Other modifications will be described below.

[0072] Although the beauty device 1 of the present invention is exemplified as a device that performs multiple treatments, such as radiofrequency treatment, ultrasound treatment, cavitation treatment, EMS, and iontophoresis, the present invention is not limited to this. The beauty device 1 may be a device that performs only radiofrequency treatment, or a device that performs radiofrequency treatment and any other treatment.

[0073] Although the embodiments of the present invention have been described in detail above, the scope of the present invention is not limited to the above-described embodiments. Furthermore, the above-described embodiments can be improved or modified in various ways without departing from the spirit of the present invention. Furthermore, the above-described embodiments and modifications can be combined, or some of them can be omitted.
