[0016] Hereinafter, one embodiment of the present invention will be described with reference to the accompanying drawings. In the following description, the same reference numerals will be used to refer to the same parts. These parts also have the same names and functions. Therefore, detailed descriptions of these parts will not be repeated.

[0017] The structure of a beauty device 1 according to one embodiment of the present invention will be described below.

[0018] (1. Summary) First, refer to Figure 1 A brief description of beauty equipment 1 is provided. For example... Figure 1 As shown, beauty device 1 is a device for performing beauty treatments on customers. For example, beauty device 1 is used by staff members of beauty salons or similar establishments as practitioners U. Beauty device 1 performs various beauty treatments, described later, on patients C who are customers of beauty salons.

[0019] Figure 1 This is a diagram showing the overall structure of beauty equipment 1. For example... Figure 1 As shown, the beauty device 1 includes a control box 10 and multiple external terminals. The external terminals include a pair of RF detectors 30, a pair of ultrasonic detectors 60, and a ground plane 40.

[0020] When the beauty device 1 uses a pair of RF detectors 30 and a ground plane 40, it performs beauty treatments on the subject C by dielectric heating of the human body. In the following description, this beauty treatment using dielectric heating will be referred to as radio frequency treatment (high frequency treatment).

[0021] Furthermore, when the beauty device 1 uses a pair of ultrasonic detectors 60, beauty treatments can be performed on the subject C by applying ultrasonic vibrations to the human body. In the following description, this type of beauty treatment by applying ultrasonic vibrations will be referred to as ultrasonic treatment and cavitation treatment. The difference between ultrasonic treatment and cavitation treatment will be described later.

[0022] Additionally, the beauty device 1 can be connected to a pair of ultrasonic detectors 60 connected to the control box 10 and an output patch 80 connected to the control box 10 (see reference). Figure 2 EMS and iontophoresis care will be implemented. The specific details of these care procedures will be described later.

[0023] The control box 10 is a control panel housed inside the casing for controlling the beauty device 1. The practitioner U, acting as a beauty salon worker, sets the operation of the control box 10 while simultaneously using external terminals to perform beauty treatments on the beauty salon's customer (the recipient C). The structure of the beauty device 1 will be described below.

[0024] (2. Structure of beauty equipment 1) Next, refer to Figures 2 to 7 The structure of beauty device 1 will be described.

[0025] (1) Control box 10 First, refer to Figure 2 Explain the structure of control box 10. Figure 2 It means Figure 1 The diagram shows the hardware structure of beauty device 1. Figure 2 As shown, 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.

[0026] The main control circuit 11 is a control circuit that, in response to input operations from the user, generates control commands and controls the wireless module 13, the display panel 15, the first oscillation circuit 20, the second oscillation circuit 50, and the third oscillation circuit 70. The main control circuit 11 is, for example, a microcomputer. The main control circuit 11 functions as a processor, memory, and communication interface IF.

[0027] A processor is a piece of hardware used to execute the instruction set of a program stored in memory. It consists of an arithmetic unit, registers, and peripheral circuits.

[0028] The memory consists of memory circuits and is a storage device used to store control instructions corresponding to the operating modes of each module. The main control unit may also use volatile memory such as DRAM (Dynamic Random Access Memory), flash memory, or HDD (Hard Disc Drive) to replace the memory circuits.

[0029] The communication interface IF is an interface used for inputting and outputting signals to enable the beauty device 1 to communicate with external devices.

[0030] The power supply circuit 12 provides the required DC power to each module contained in the control box 10 based on the power output from the AC adapter 12A.

[0031] The wireless module 13 responds to control commands from the main control circuit 11 and communicates wirelessly with external devices. For example, the wireless module 13 communicates wirelessly with wireless base stations that support communication standards such as 5G and LTE (Long Term Evolution), or wireless LAN routers that support wireless local area network (LAN) standards such as IEEE (Institute of Electrical and Electronics Engineers) 802.11.

[0032] The operation switch 14 is an input device that receives input from the user. The operation switch 14 can also be a touchpad, mouse, or other pointing device, or a keyboard or other input device.

[0033] Display panel 15 is a display device that displays information related to the control of beauty device 1. For example, display panel 15 is a liquid crystal display. Display panel 15 displays various information according to liquid crystal control signals input from main control circuit 11.

[0034] (2) Oscillating circuit The following describes the structure of the oscillation circuit. Beauty device 1 generally includes three types of oscillation circuits. For example... Figure 2 As shown, the control box 10 includes a first oscillation circuit 20, a second oscillation circuit 50, and a third oscillation circuit 70. These will be described below.

[0035] (2-1) First oscillation circuit 20 The first oscillation circuit 20 is a circuit that generates a high-frequency voltage based on the input power control signal from the main control circuit 11. The first oscillation circuit 20 includes a power supply circuit. The first oscillation circuit 20 is a CR oscillation circuit with a capacitor and a resistor. In this case, the first oscillation circuit 20 generates a high-frequency voltage by charging and discharging the capacitor. It should be noted that the first oscillation circuit 20 can also be an LC circuit with a coil and a capacitor. In this case, the first oscillation circuit 20 generates a high-frequency voltage by oscillating through energy exchange between the coil and the capacitor. For example, the first oscillation circuit 20 generates a 300kHz high-frequency voltage. The frequency of the voltage generated by the first oscillation circuit can be arbitrarily set.

[0036] A pair of RF detectors 30 and a ground plane 40, serving as external terminals, are connected to the first oscillation circuit 20. The first oscillation circuit 20, together with the RF detectors 30 and the ground plane 40, functions as a high-frequency device for performing radiofrequency treatment. The construction of the RF detectors 30 and the ground plane 40 will be described later.

[0037] (2-2) Second oscillation circuit 50 The second oscillation circuit 50 is a circuit that generates an AC signal of a predetermined frequency based on the input power control signal from the main control circuit 11. The second oscillation circuit 50 includes a power supply circuit. The second oscillation circuit 50 is a CR oscillation circuit with a capacitor and a resistor. In this case, the second oscillation circuit 50 generates a high-frequency voltage by charging and discharging the capacitor. It should be noted that the second oscillation circuit 50 can also be constructed from an LC circuit with a coil and a capacitor. In this case, the second oscillation circuit 50 applies the AC signal generated by the LC circuit to the vibrator, causing the vibrator built into the ultrasonic detector 60 to vibrate.

[0038] The second oscillation circuit 50 is connected to the ultrasonic detector 60. The second oscillation circuit 50 and the ultrasonic detector 60 work together to perform the functions of ultrasonic care and ultrasonic beauty devices. The structure of the ultrasonic detector 60 will be described later.

[0039] The second oscillation circuit 50 includes an ultrasonic oscillation circuit 51 and a cavitation oscillation circuit 52. The ultrasonic oscillation circuit 51 generates a 1.5 MHz AC signal. The ultrasonic oscillation circuit 51 generates a signal for ultrasonic care. The cavitation oscillation circuit 52 generates a 36 kHz AC signal. The cavitation oscillation circuit 52 generates a signal for cavitation care.

[0040] The ultrasonic oscillation circuit 51 includes a first ultrasonic oscillation circuit 51A and a second ultrasonic oscillation circuit 51B. The first ultrasonic oscillation circuit 51A and the second ultrasonic oscillation circuit 51B have the same structure as each other.

[0041] The cavitation oscillation circuit 52 includes a first cavitation oscillation circuit 52A and a second cavitation oscillation circuit 52B. The first cavitation oscillation circuit 52A and the second cavitation oscillation circuit 52B have the same structure.

[0042] In the second oscillation circuit 50, the first ultrasonic oscillation circuit 51A and the first cavitation oscillation circuit 52A constitute a series-connected multiple oscillation circuit. Furthermore, the output terminals of either the first ultrasonic oscillation circuit 51A or the first cavitation oscillation circuit 52A are bridged by a capacitor.

[0043] Therefore, in the second oscillation circuit 50 of the present invention, by making the first ultrasonic oscillation circuit 51A and the first cavitation oscillation circuit 52A work simultaneously, the state in which the AC signal generated by the first ultrasonic oscillation circuit 51A and the AC signal generated by the first cavitation oscillation circuit 52A are superimposed on each other can be applied to the vibrator.

[0044] The ultrasonic waves generated by the vibration of the vibrator due to the superimposed AC signals constitute a composite wave of the ultrasonic waves generated by the AC signals generated from the first ultrasonic oscillation circuit 51A and the ultrasonic waves generated by the AC signals generated from the first cavitation oscillation circuit 52A. It should be noted that the first ultrasonic oscillation circuit 51A and the first cavitation oscillation circuit 52A can also operate independently.

[0045] Furthermore, the connection structure of the second ultrasonic oscillation circuit 51B and the second cavitation oscillation circuit 52B is the same as that of the first ultrasonic oscillation circuit 51A and the first cavitation oscillation circuit 52A. Therefore, by making the second ultrasonic oscillation circuit 51B and the second cavitation oscillation circuit 52B work simultaneously, the ultrasonic waves generated by the two oscillation circuits are combined and output as a single unit. It should be noted that the second ultrasonic oscillation circuit 51B and the second cavitation oscillation circuit 52B can also work independently.

[0046] (2-3) Third oscillation 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 for EMS (Electrical Muscle Stimulation), which is used to apply low-frequency electrical stimulation of a few Hz to several hundred Hz to the human body.

[0047] In addition, the third oscillation circuit 70 also generates an electrical signal for iontophoresis. Iontophoresis is a technique that uses a weak current to ionize cosmetic ingredients present in the skin, allowing them to penetrate into the skin. The third oscillation circuit 70 is equipped with a power supply circuit.

[0048] (3) External terminal Next, refer to Figure 2 The structure of the external terminals of beauty device 1 will be described. For example... Figure 2 As shown, the beauty device 1 includes an RF detector 30, a ground plane 40, an ultrasonic detector 60, and an output patch 80 as external terminals. These structures will be described below.

[0049] (3-1) RF detector 30 The RF detector 30 provides radio frequency (RF) protection to its output terminal by radiating high-frequency electromagnetic waves. The RF detector 30 radiates electromagnetic waves when a high-frequency voltage generated by the first oscillation circuit 20 is applied.

[0050] The RF detector 30 includes a first RF detector 30A and a second RF detector 30B. During radiofrequency ablation, the practitioner U holds one of the first RF detector 30A and the second RF detector 30B with either hand. The first RF detector 30A and the second RF detector 30B have identical structures. Both the first RF detector 30A and the second RF detector 30B are connected to the first oscillation circuit 20.

[0051] RF detector 30 has electrode 35 (see Figure 4B Electrode 35 radiates electromagnetic waves when a high-frequency voltage generated by the first oscillation circuit 20 is applied. As a result, the RF detector 30 dielectrically heats the treatment site for radiofrequency therapy. The detailed structure of the RF detector 30 will be described later.

[0052] (3-2) Floor joint 40 Grounding plate 40 is a component used to ground the electromagnetic waves radiated by electrode 35. Grounding plate 40 is made of conductive material. When exposed to electromagnetic radiation, grounding plate 40 generates an internal current, thereby appropriately dissipating electromagnetic waves received by the human body. During use, grounding plate 40 is placed between the patient C and the operating table and is in contact with the patient C.

[0053] (3-3) Ultrasonic detector 60 The ultrasonic detector 60 is an output terminal used for ultrasonic and cavitation treatments. The ultrasonic detector 60 has a vibrator that vibrates when an AC signal generated by the second oscillation circuit 50 is applied. The ultrasonic detector 60 includes a first ultrasonic detector 60A and a second ultrasonic detector 60B. During ultrasonic and cavitation treatments, the practitioner U holds one of the first ultrasonic detector 60A or the second ultrasonic detector 60B with either hand.

[0054] The first ultrasonic detector 60A is connected in series with the first ultrasonic oscillation circuit 51A and the first cavitation oscillation circuit 52A. Therefore, the vibrator of the first ultrasonic detector 60A vibrates under the influence of the composite wave formed by the 1.5MHz ultrasonic wave generated by the first ultrasonic oscillation circuit 51A and the 36kHz ultrasonic wave generated by the first cavitation oscillation circuit 52A, thus stimulating the treatment site. Therefore, the first ultrasonic detector 60A can simultaneously perform ultrasonic therapy and cavitation therapy.

[0055] The second ultrasonic detector 60B is connected in series with the second ultrasonic oscillation circuit 51B and the second cavitation oscillation circuit 52B. Therefore, the vibrator of the second ultrasonic detector 60B vibrates under the combined effect of the 1.5MHz ultrasonic wave generated by the second ultrasonic oscillation circuit 51B and the 36kHz ultrasonic wave generated by the second cavitation oscillation circuit 52B, thus stimulating the treatment site. Therefore, the second ultrasonic detector 60B can simultaneously perform ultrasonic therapy and cavitation therapy.

[0056] (3-4) Output patch 80 The output patch 80 is an output terminal used for EMS and iontophoresis. The output patch 80 is formed of a conductive material. The output patch 80 is connected to the third oscillation circuit 70. In EMS, current flows through the output patch 80, transmitting electrical stimulation to the muscles. In iontophoresis, current flows through the output patch 80 to effectively ionize and penetrate the skin's cosmetic ingredients. The current supplied to the output patch 80 is also output to the ultrasound detector 60 via wiring within the control box 10.

[0057] (3. Detailed structure of RF detector 30) Next, refer to Figures 3A to 4B The detailed structure of the RF detector 30 is described below. Figure 3A This is a side view of the RF detector 30. Figure 3B This is a three-dimensional view of the detector probe 32 in the RF detector 30. (See image below.) Figure 3A As shown, the RF detector 30 has a detector body 31 and a detector probe 32.

[0058] (1) Detector body 31 The detector body 31 is the component held by the practitioner U. The detector body 31 is formed of an insulating synthetic resin material. The detector body 31 has a gripping part (not shown in the figure) for the practitioner U to hold.

[0059] The detector probe 32 is a component connected to the lower part of the detector body 31. For example... Figure 3BAs shown, the detector probe 32 is a bottomed cylindrical shape. The detector probe 32 is formed of synthetic resin material. The bottom 32B of the detector probe 32 contacts the treatment site of the subject C during operation by the practitioner U.

[0060] A cable 34 is threaded through the inside of the detector probe 32. A flange 32A protruding radially outward is formed at the upper end of the detector probe 32. The flange 32A engages with the inside of the detector body 31, thereby connecting the detector body 31 and the detector probe 32. The detector probe 32 is mounted on the detector body 31.

[0061] (2) Detector probe 32 Figure 4A This is a top view of the detector probe 32. Figure 4B It is along Figure 4A A cross-sectional view of the detector probe 32 of the IVB-IVB line. (See attached image.) Figure 4A As shown, the bottom 32B of the detector probe 32 houses an electrode substrate 33. Figure 4B As shown, the electrode substrate 33 is fixed by being embedded in the resin molding part 32C while the cable 34 is connected.

[0062] (3) Electrode substrate 33 like Figure 4B As shown, the electrode substrate 33 is disposed on the bottom 32B of the detector probe 32 and is insulated and fixed by the resin molding part 32C. The electrode substrate 33 has a substrate body 36 and an electrode 35. The substrate body 36 is an annular shape with a radially open center. The electrode 35 is disposed on the back side of the substrate body 36.

[0063] The substrate body 36 has a glass layer 36A and a resin layer 36B, forming a double-layer structure. The glass layer 36A constitutes the surface layer of the substrate body 36 and is annular. The resin layer 36B constitutes the bottom layer of the substrate body 36. The resin layer 36B bonds the electrode 35 to the back side of the glass layer 36A.

[0064] Thus, since the surface of the substrate body 36 is a glass layer 36A, it is possible to suppress the heat generated by the electrode 35 laid on the back of the substrate body 36 from the surface of the substrate body 36 to the inside of the detector probe 32.

[0065] Electrode 35 is a copper foil and is bonded to glass layer 36A via resin layer 36B. Electrode 35 is in contact with the upper surface of bottom 32B of detector probe 32. With electrode substrate 33 placed on bottom 32B of detector probe 32, electrode substrate 33 is fixed to bottom 32B of detector probe 32 by filling bottom 32B of detector probe 32 with molding resin.

[0066] Next, refer to Figure 5 and Figure 6 The shape of electrode 35 will be described. Figure 5 This is a bottom view of the electrode substrate 33. (Example) Figure 5 As shown, on the back side of the substrate body 36, electrodes 35 are disposed in the area excluding the radial center portion and extend radially. In the illustrated example, four radially extending straight portions are formed. Thus, because the electrodes 35 extend radially, the area in the bottom 32B of the RF detector 30 that generates electromagnetic waves can be kept uniform throughout the entire radial range.

[0067] On the back side of the substrate body 36, electrodes 35 are also disposed in the area excluding the radial center portion, and extend in a ring shape along the circumference. In the illustrated example, three ring portions with different diameters are coaxially arranged. Thus, because the electrodes 35 extend in a ring shape, the area in the bottom 32B of the RF detector 30 that generates electromagnetic waves can be kept uniform throughout the entire circumferential region. It should be noted that... Figure 5 and Figure 6 In this design, although electrode 35 is disposed in an area other than the radial center and extends in a ring shape along the circumference, electrode 35 could also be disposed in the radial center. However, since electrode 35 is not disposed in the radial center, mold forming is easier.

[0068] Furthermore, since the electrode 35 is composed of multiple straight sections and multiple annular sections, it is possible to increase the area occupied by the electrode 35 on the back side of the substrate body 36 while reducing the local area of ​​the electrode 35. This suppresses heat diffusion and enables uniform electromagnetic wave output from a larger area of ​​the detector probe 32.

[0069] The detector probe 32 is heated when it outputs electromagnetic waves. At this time, if the area of ​​electrode 35 is large, the heat will diffuse to electrode 35, making it difficult for the subject C to feel the warmth. On the other hand, because the area of ​​electrode 35 is small, the heat generated when outputting electromagnetic waves is not easily diffused and can be concentrated, thereby increasing the perceived temperature of the subject C.

[0070] Figure 6 This is a top view of the electrode substrate 33. (Example) Figure 6 As shown, a connection portion 37, which forms part of the electrode 35 and is connected to the cable 34, is formed on the upper surface of the electrode substrate 33. By connecting the cable 34 to the connection portion 37, the high-frequency voltage generated by the first oscillation circuit 20 is supplied to the electrode 35.

[0071] (4) Example of deformation of electrode 35 Next, refer to Figure 7 A modified example of electrode 35 will be described. Figure 7This is a bottom view of the electrode substrate 33A involved in the modified example. (See attached image.) Figure 7 As shown, in the electrode substrate 33A of the modified example, the radially outer end portion 35A of the electrode 35 is circular. In the illustrated example, eight circular outer end portions 35A are arranged at equal intervals along the circumference. Thus, since the outer end portions 35A of the electrode 35 are circular, electromagnetic waves can be efficiently output from the outer end portions 35A, where output is easily attenuated.

[0072] When the area of ​​electrode 35 increases, its capacitance increases from the perspective of the output circuit (transformer). When the capacitance of detector probe 32 is too large, its impedance to the hundreds of kHz high-frequency voltage generated by the first oscillation circuit 20 decreases. As a result, the input current increases, the transformer load increases and heat is generated, leading to a drop in output voltage. In addition, simply increasing the area of ​​electrode 35 requires a larger power supply. By configuring electrode 35 as copper foil on electrode substrates 33, 33A, it is possible to maintain the capacitance value of detector probe 32 while ensuring that the RF detector 30 outputs electromagnetic waves uniformly throughout.

[0073] (4. Summary) As described above, in the beauty device 1 of the present invention, the RF detector 30 has an electrode substrate 33 on which electrodes 35 are disposed. Therefore, while keeping the shape of the substrate body 36 in the electrode substrate 33 unchanged, the shape of the electrodes 35 can be easily changed. Therefore, by appropriately adjusting the shape of the electrodes 35, the electromagnetic waves output by the RF detector 30 can be adjusted. For example, by changing the shape of the electrodes 35 according to the required specifications of the RF detector 30, it is possible to increase the area occupied by the electrodes 35 at the bottom 32B of the detector probe 32 while reducing the local area of ​​the electrodes 35.

[0074] Therefore, during beauty treatments, when the RF detector 30 radiates electromagnetic waves, it can radiate high-output electromagnetic waves from a large area at the bottom 32B of the detector probe 32. Furthermore, because the shape of the electrode 35 laid on the substrate body 36 is given greater design freedom, the shape of the electrode 35 can be changed according to the required specifications of the beauty device 1, thereby allowing for arbitrary adjustment of the electromagnetic wave output.

[0075] Furthermore, in the beauty device 1 of the present invention, by reducing the local area of ​​the electrode 35, a higher output can be obtained from the bottom 32B of the detector probe 32 when the RF detector 30 radiates electromagnetic waves. To elaborate further, in conventional beauty devices, as the number of detectors increases, the electromagnetic wave output by each detector decreases due to the increased surface area of ​​the electrodes. However, in the beauty device 1 of the present invention, as described above, the surface area of ​​the electrode 35 can be reduced by changing its shape.

[0076] Therefore, in the beauty device 1 of the present invention, although multiple RF detectors 30 are provided, the output reduction of each RF detector 30 can be suppressed, so that each RF detector 30 can obtain sufficient output. Furthermore, since the beauty device 1 has multiple RF detectors 30, the operation time during beauty treatments can be significantly shortened, improving user convenience.

[0077] Furthermore, the beauty device 1 of the present invention combines the functions of a high-frequency beauty device, an ultrasonic beauty device, an EMS beauty device, and an iontophoresis beauty device, thus enabling the use of one device to perform multiple treatments such as radiofrequency treatment, ultrasonic treatment, cavitation treatment, EMS, and iontophoresis.
