[0028] Hereinafter, the embodiments will be described in detail with reference to the accompanying drawings. However, detailed description sometimes will be omitted. For example, a detailed description of matters which are already known will be omitted, or repetitive description of substantially identical configurations will be omitted. In addition, the drawings and the following description are provided to enable those skilled in the art to sufficiently understand the present disclosure, and are not intended to limit the subject matter recited in the claims by the drawings.

[0029] Figure 1A is a perspective view showing the appearance of the cosmetic device 10 according to the present embodiment. In addition, Figure 1B is a rear view showing the appearance of the cosmetic device 10 according to the present embodiment. Also, Figure 1C is a graph for explaining the electrode configuration of the cosmetic device 10 according to the present embodiment.

[0030] As Figure 1AAs shown, in this embodiment, the beauty device 10 is an electrode used to apply first electrical stimulation to the user's skin by contacting the skin, and has at least two or more first electrodes 11. Each first electrode 11 is composed of multiple pins. In this embodiment, each first electrode is composed of a single pin. Additionally, the beauty device 10 includes a power switch 12 and a level switch 13.

[0031] Furthermore, in this specification, Figure 1A The short side of the side of the beauty device 10 shown, which includes the first electrode 11, power switch 12, and level switch 13, is defined as the X-axis direction. Furthermore, the X-axis direction is... Figure 1A The length direction of the side of the beauty device 10 shown, which includes the first electrode 11, power switch 12, and level switch 13, is defined as the Z-axis direction. Furthermore, from... Figure 1A The depth direction (thickness direction of the beauty device 10) of the side of the beauty device 10 that has the first electrode 11, power switch 12 and level switch 13 is defined as the Y-axis direction.

[0032] like Figure 1A As shown, the first electrode 11 is formed in the shape of a brush and extends along the Y-axis. In this embodiment, the user places the first electrode 11 against the skin, so that the skin receives a first electrical stimulation or a second electrical stimulation from the first electrode 11, thereby achieving the effect of tightening the skin and the cosmetic effect based on cosmetic ingredients.

[0033] The power switch 12 is a switch pressed by the user and is used to switch the power supply of the beauty device 10 on and off. In this embodiment, the power switch 12 also has the function of switching the usage mode applied in the beauty device 10. Details of the usage mode will be described later. Furthermore, the beauty device 10 may also have a function that automatically disconnects the power after a predetermined time has elapsed since the start of use. For example, the predetermined time may be 6 minutes after the start of use, thereby preventing overuse of the usage mode.

[0034] Level switch 13 is a switch pressed by the user and is used to set the voltage level (energization level) of the electrical stimulation. Details of the levels will be described later.

[0035] In addition, such as Figure 1B As shown, the beauty device 10 has a second electrode 14 on the back of its main body. The second electrode 14 is located in the position held by the user in the beauty device 10. In this embodiment, when the user holds the beauty device 10, by bringing the first electrode 11 into contact with the skin, a second electrical stimulation current can flow between the first electrode 11 and the second electrode 14.

[0036] Furthermore, when the first electrical stimulation is output, the first electrode 11 is in the left-right direction ( Figure 1A In the X-axis direction, it becomes a heteropolar structure. That is, the multiple pins of the first electrode 11 include multiple pins composed of positive electrodes and multiple pins composed of negative electrodes. Figure 1C The example shown illustrates a case where the left side when facing the diagram is designated as the positive pole (+) and the right side when facing the diagram is designated as the negative pole (-). Furthermore, in this embodiment, as... Figure 1C As shown, each pole is equipped with 16 pins.

[0037] In this embodiment, the area of ​​the region where the first electrode 11 is disposed, represented by the shape formed by connecting the outermost shapes of the first electrode 11, can be, for example, 1480 mm². 2 Below. Figure 1C In the example shown, the region A1 where the first electrode 11 is configured is 46mm × 32mm = 1472mm, with a vertical length L of 46mm and a horizontal width W1 of 32mm. 2 Examples of this situation. Generally speaking, in terms of the contact area between the electrode and the skin, the larger the area where the electrode is located, the smaller the electrode area per unit area, the less stable the current is applied, and the less stimulation is felt. In the beauty device 10 according to this embodiment, the area A1 where the first electrode 11 is disposed is set to 1480 mm². 2 Therefore, it is possible to apply a stable current and provide a more appropriate stimulation.

[0038] Additionally, the area of ​​region A2 sandwiched between the opposite poles of the first electrode 11 can, for example, be 200 mm². 2 Above and 400mm 2 Below. Figure 1C In the example shown, the area of ​​region A2 sandwiched between the opposite poles of the first electrode 11 is 46mm × 6mm = 252mm, with a length L of 46mm and a width W2 of 6mm. 2 Examples of this situation. Generally speaking, the larger the area between the opposite poles, the more muscle can be surgically stimulated by electrical stimulation, and the larger the area that can be stimulated. Conversely, if the area is too large, the current is dispersed in devices where voltage and current are limited for safety, resulting in a lack of usability. In this embodiment, the beauty device 10 sets the area of ​​region A2 between the opposite poles to 200 mm². 2 Above and 400mm 2 The following will provide a more suitable user experience.

[0039] (Structure of beauty equipment 10)

[0040] Next, refer to Figure 2The structure of the cosmetic device 10 according to the present embodiment will be described. Figure 2 Fig. 1 is a block diagram schematically showing each structure of the cosmetic device 10 according to the present embodiment.

[0041] As shown in Fig. 1, the cosmetic device 10 is configured to include an electrode control device 100, a first electrode 11, a power switch 12, a level switch 13, and a second electrode 14. Figure 2

[0042] The electrode control device 100 can also be configured to have a system including a control section 110 (CPU), a storage section 120 (memory), and an input / output IF 130 (interface). In this case, a computer program for functioning as the electrode control device 100 can also be installed in the microcomputer. The microcomputer functions as the plurality of information processing circuits included in the electrode control device 100 by executing the computer program.

[0043] Further, in the present embodiment, an example in which the plurality of information processing functions included in the electrode control device 100 are realized by software is shown. The electrode control device 100 functions as the plurality of information processing circuits included in the electrode control device 100 by executing the computer program.

[0044] In addition, as other structures, the electrode control device 100 can also be prepared with dedicated hardware for executing each information processing function and configured by a system LSI (Large Scale Integration) or the like. In addition, a system in which the plurality of information processing functions are configured by separate hardware can also be used. Details of the control section 110 and the storage section 120 will be described later.

[0045] The control section 110 functions based on a program (not shown) stored in the storage section 120 to execute each function included in the electrode control device 100. Further, the program is not limited to the manner of being stored in the storage section 120, and can be configured to be stored in a ROM or the like (not shown) in the cosmetic device 10, for example. As shown in Fig. 1, the control section 110 includes a mode information acquisition section 111, a level information acquisition section 112, a frequency setting section 113, a voltage setting section 114, and an electrode control section 115 as functions. Figure 3

[0046] As shown in Fig. 1, the storage section 120 stores information stored in a setting information DB 121 (Data Base) as data in the storage section 120. Figure 3 Figure 4A Figure 4B ​​​​is a diagram showing an example of the setting information stored in the setting information DB 121. Details of these setting information are described later.

[0047] In addition, as described above, the storage section 120 can also store programs for each function executed in the control section 110. Further, the information and programs stored in the storage section 120 can be configured as regions that are physically or logically separated in one storage device. Alternatively, it can be configured that the storage section 120 of each data is provided in a plurality of storage devices that are physically different.

[0048] The input / output IF 130 is an interface for transmitting and receiving information exchanged between the electrode control device 100 and the first electrode 11, the power switch 12, the level switch 13, and the second electrode 14 provided in the beauty device 10.

[0049] For example, information about the power switch 12 and the level switch 13 pressed by the user is transmitted to the control section 110 and / or the storage section 120 via the input / output IF 130. In addition, control information for the first electrode 11 and the second electrode 14 from the control section 110 is transmitted to the first electrode 11 and the second electrode 14 via the input / output IF 130.

[0050] (Function of the electrode control device 100)

[0051] Figure 3 is a block diagram showing the functional configuration of the electrode control device 100. As shown in Figure 3 As described above, the control section 110 of the electrode control device 100 has the mode information acquisition section 111, the level information acquisition section 112, the frequency setting section 113, the voltage setting section 114, and the electrode control section 115 as functions. In addition, the storage section 120 of the electrode control device 100 has the setting information DB 121 as a database that stores setting information.

[0052] The mode information acquisition section 111 acquires mode information indicating a kind of a waveform of the first electric stimulus and / or the second electric stimulus imparted from the first electrode 11 and / or the second electrode 14. In the present embodiment, the beauty device 10 has a first mode and a second mode. The first mode is a scalp mode, which corresponds to a mode in which the electric stimulus is imparted to the scalp of the user. In addition, the second mode is a face mode, which corresponds to a mode in which the electric stimulus is imparted to the face of the user.

[0053] In the present embodiment, the mode information is acquired from information from the power switch 12 pressed by the user. For example, by the user pressing the power switch 12, the cosmetic device 10 is activated in the first mode, and by the user pressing the power switch 12 again, the cosmetic device 10 is switched to the second mode. Further, the user can also stop the processing of the cosmetic device 10 by long-pressing the power switch 12. Alternatively, it can also be configured that the cosmetic device 10 is stopped by the user pressing the power switch 12 in the state of the second mode.

[0054] Figure 4A is a diagram for explaining the respective modes in the present embodiment and the electrical stimulation imparted thereby. Further, in the present embodiment, the first electrical stimulation is the electrical stimulation imparted between the electrodes of the plurality of first electrodes 11, corresponds to EMS pulse (Electrical Muscle Stimulation), and realizes a muscle movement effect. In addition, in the present embodiment, the second electrical stimulation is the electrical stimulation imparted between the first electrode 11 and the second electrode 14, corresponds to IP pulse (Iontophoresis), and realizes a penetration effect of the cosmetic ingredient.

[0055] The first mode imparts the first electrical stimulation in a time proportion of 33.3% of the whole. In addition, the second mode imparts the first electrical stimulation in a time proportion of 5.2% of the whole and imparts the second electrical stimulation in a time proportion of 67.8% of the whole. Details of the electrical stimulation in these respective modes are described hereinafter.

[0056] The level information acquisition section 112 acquires level information indicating the voltage of the first electrical stimulation and / or the second electrical stimulation based on the press information of the level switch 13. Figure 4B is the level information in the present embodiment. As shown in Figure 4B , the user sets the voltage value corresponding to each level by pressing the level switch 13 of the cosmetic device 10. Further, the level information corresponds to the voltage level information.

[0057] The frequency setting section 113 sets frequency information indicating the characteristics of the frequency of the first electrical stimulation and / or the second electrical stimulation imparted to the first electrode 11 and / or the second electrode 14 based on the mode information. Specifically, the frequency setting section 113 sets the frequency information indicating the characteristics of the frequency of the first electrical stimulation and / or the second electrical stimulation based on the acquired mode information, with reference to the setting information saved in the setting information DB 121.

[0058] The voltage setting section 114 sets the voltage level of the first electric stimulus and / or the second electric stimulus to be imparted to the first electrode 11 and / or the second electrode 14, on the basis of the level information. Specifically, the voltage setting section 114 sets the voltage level of the first electric stimulus and / or the second electric stimulus on the basis of the level information, with reference to the setting information stored in the setting information DB 121.

[0059] The electrode control section 115 imparts the first electric stimulus and / or the second electric stimulus to the first electrode 11 and the second electrode 14, on the basis of the frequency information and the voltage level. Specifically, the electrode control section 115 generates the first electric stimulus in such a manner that the pulse shape of the first electric stimulus becomes a two-sided rectangular wave in which a positive-side rectangular wave and a negative-side rectangular wave are alternately included, and imparts the first electric stimulus to the first electrode 11. Alternatively, the electrode control section 115 generates the second electric stimulus in such a manner that the pulse shape of the second electric stimulus becomes a single-sided rectangular wave of the positive side, and imparts the second electric stimulus to the first electrode 11 and the second electrode 14. Examples of the waveforms of these first electric stimulus and second electric stimulus are described with reference to Figure 5A~Figure 5B Figure 6A~Figure 6C Figure 7A~Figure 7B

[0060] (First mode: scalp mode)

[0061] Figure 5A is a graph showing the waveform of the first electric stimulus imparted in the first mode (scalp mode). In addition, Figure 5B is a graph for explaining the basic waveform of the first electric stimulus imparted in the first mode. Furthermore, Figure 5A the waveform shown in Figure 5B is a graph schematically showing the change in the pulse width of the basic waveform shown in Figure 5B The basic waveform shown in Figure 5A corresponds to the basic waveform in the vicinity of the central portion ofThe electrode control section 115 generates the shape of the pulse on the basis of the frequency information. In addition, the electrode control section 115 determines the voltage value of the pulse on the basis of the voltage level.

[0062] In addition, in the first mode, the beauty device 10 generates the first electric stimulus by repeatedly performing the increase and decrease of the pulse width. That is, in the example shown in Figure 5A the following example is shown: from the left side of the waveform, the pulse width increases with the passage of time, and after exceeding 500 ms, the pulse width decreases with the passage of time. In this way, in the first mode in the present embodiment, the pulse width of the electric stimulus is repeatedly increased and decreased with the passage of time, whereby the user can be given a sense of use of the skin that is gentle or severe according to the degree of increase and decrease.

[0063] In addition, as Figure 5B ​​As shown, the voltage of the first electric stimulus is composed of two-sided rectangular waves alternately containing rectangular waves having a pulse shape of a positive side and a negative side. In addition, the electrode control section 115 changes the pulse width of the two-sided rectangular waves based on the frequency information. In this way, in the present embodiment, the electrode control section 115 composes the voltage of the first electric stimulus by the two-sided rectangular waves corresponding to the positive and negative sides, thereby being able to prevent the polarization phenomenon of the user's skin and being able to give the user a comfortable stimulation feeling.

[0064] In addition, in the present embodiment, the carrier frequency of the first electric stimulus output from the first electrode 11 can also be 1 kHz to 10 kHz. In general, it is known that the human skin is equivalent to a parallel circuit having a resistor component and a capacitor component. In this way, the cosmetic device 10 according to the present embodiment is able to reduce the resistance of the skin and perform effective electrification by setting the carrier frequency to an intermediate frequency of 1 kHz to 10 kHz.

[0065] In addition, in the present embodiment, the maximum pulse width of the two-sided rectangular waves can also be half or less (50% or less) of the wavelength of the carrier frequency. Thereby, in the present embodiment, the cosmetic device 10 is able to prevent the polarization phenomenon of the user's skin and be able to give the user a comfortable stimulation feeling by making the maximum pulse width of the two-sided rectangular waves half or less of the wavelength of the carrier frequency.

[0066] In addition, the electrode control section 115 can also make the effective value of the first electric stimulus repeatedly increase and decrease in a sinusoidal wave shape based on the frequency information. Thereby, the cosmetic device 10 according to the present embodiment is able to give the user a stimulation having fluctuations by making the effective value of the first electric stimulus repeatedly increase and decrease in a sinusoidal wave shape.

[0067] Also, the period of the increase and decrease of the effective value of the first electric stimulus can also be 1 Hz to 20 Hz. Thereby, the cosmetic device 10 according to the present embodiment is able to give the user a stimulation corresponding to the degree of increase and decrease by setting the period of the increase and decrease of the effective value of the first electric stimulus to 1 Hz to 20 Hz, thereby giving a more comfortable stimulation.

[0068] In addition, in the present embodiment, the maximum value of the voltage of the first electric stimulus is 20 V or less. Thereby, the cosmetic device 10 according to the present embodiment is able to give the user a more comfortable stimulation feeling without applying a high voltage.

[0069] (Second mode: face mode)

[0070] Figure 6A is a diagram showing the structure of the waveforms of the first electric stimulus and the second electric stimulus given in the second mode (face mode). In addition, Figure 6Bis a diagram showing an example of a waveform of the first electric stimulus in the basic waveform constituting the waveform A and the waveform B in the second mode. In addition, Figure 6C is a diagram showing an example of a waveform of the second electric stimulus in the basic waveform constituting the waveform A and the waveform B in the second mode.

[0071] In addition, Figure 7A is a diagram showing Figure 6A the structure of the waveform A in the second mode. Also, Figure 7B is a diagram showing Figure 6A the structure of the waveform B in the second mode.

[0072] As Figure 6A~Figure 6C and Figure 7A~Figure 7B shown, in the second mode, the electric stimulus based on the waveform A of the prescribed number of times and the waveform B of the prescribed number of times are repeatedly implemented. In the present embodiment, as Figure 6A shown, the prescribed number of times is five. In addition, the prescribed number of times is not limited to the structure of the present embodiment, and can be a number of times less than five or more than five.

[0073] In the second electric stimulus based on the IP pulse based on the second mode, the polarity of the voltage of the plurality of first electrodes 11 is the same, and in addition, the polarity of the voltage of the plurality of first electrodes 11 is different from the polarity of the voltage of the second electrode 14. Thereby, the cosmetic device 10 can enable the user to simultaneously obtain the muscle movement effect based on the EMS pulse and the penetration effect of the cosmetic ingredient based on the IP pulse without switching the setting by setting the polarity of the first electrode 11 and the second electrode 14.

[0074] In addition, in the second mode, the frequency of the IP pulse of the second electric stimulus can also be 1 kHz to 10 kHz. Thereby, the cosmetic device 10 can further penetrate the cosmetic ingredient to the deep part of the stratum corneum by setting the frequency of the IP pulse of the second electric stimulus to 1 kHz to 10 kHz, and thereby can effectively obtain the penetration effect of the cosmetic ingredient.

[0075] Also, in the second mode, the EMS pulse of the first electric stimulus and the IP pulse of the second electric stimulus are alternately output in different time periods. Also, in the second mode, the application time of the first electric stimulus is shorter than the second electric stimulus. Thereby, the cosmetic device 10 can obtain the effect of tightening the skin by vibrating the facial muscles of the user by the electric signal, and can improve the cosmetic effect of the cosmetic ingredient by penetrating the cosmetic ingredient to the deep part of the stratum corneum of the user.

[0076] (Outline of the processing flow of the electrode control device 100)

[0077] Next, based on Figure 8The flowchart describes the processing (electrode control method) involved in the state determination in the electrode control device 100. Figure 8 The series of actions of the electrode control device 100 shown in the flowchart begins when the electrode control device 100 is activated and ends when the power is disconnected. Additionally, Figure 8 The flowchart shown, in addition to power disconnection, also terminates the process through an interruption indicating the end of the process. Furthermore, in the following description of the flowchart, content identical to that described in the above description of the electrode control device 100 will be omitted or simplified.

[0078] In step S801, the pattern information acquisition unit 111 acquires pattern information indicating the type of waveform of the first electrical stimulation and / or the second electrical stimulation applied by the first electrode 11 and / or the second electrode 14. In this embodiment, the beauty device 10 has a first mode and a second mode. The first mode is a scalp mode, which corresponds to a mode that applies electrical stimulation to the user's scalp. The second mode is a face mode, which corresponds to a mode that applies electrical stimulation to the user's face. Furthermore, in this embodiment, the pattern information is acquired based on information from the power switch 12 pressed by the user. Afterwards, the process proceeds to step S802.

[0079] In step S802, the level information acquisition unit 112 acquires level information representing the voltage of the first electrical stimulation and / or the second electrical stimulation based on the pressed information of the level switch 13. Then, the process proceeds to step S803.

[0080] In step S803, the frequency setting unit 113 sets frequency information based on the mode information, representing the characteristics of the frequency of the first electrical stimulation and / or the second electrical stimulation applied to the first electrode 11 and / or the second electrode 14. Then, the process proceeds to step S804.

[0081] In step S804, the voltage setting unit 114 sets the voltage level of the first electrical stimulation and / or the second electrical stimulation applied to the first electrode 11 and / or the second electrode 14 based on the level information. Afterwards, the process proceeds to step S805.

[0082] In step S805, the electrode control unit 115 applies first electrical stimulation and / or second electrical stimulation to the first electrode 11 and the second electrode 14 based on frequency information and voltage level. Specifically, the electrode control unit 115 applies... Figure 5A and Figure 5B The first electrical stimulation (EMS pulse) of the first mode shown, or Figure 6A~Figure 6C and Figure 7A~Figure 7B The second mode is shown with a first electrical stimulation (EMS pulse) and a second electrical stimulation (IP pulse). Afterwards, the process proceeds to step S806.

[0083] In step S806, the control section 110 determines whether or not the electrode control is ended. In the present embodiment, the determination of whether or not the electrode control is ended is implemented based on the press information of the power switch 12. In addition, as described above, the end of the electrode control can also be implemented by automatically turning off the power after a prescribed time elapses from the use of the beauty device 10. In step S806, the control section 110 ends the process in a case where it is determined that the electrode control is ended (step S806: YES). On the other hand, in step S806, the control section 110 returns the process to step S805 and repeatedly implements the process from step S805 in a case where it is determined that the electrode control is not ended (step S806: NO). That is, the control section 110 repeatedly implements the electrode control process of step S805 until the electrode control is ended.

[0084] As described above, the beauty device 10 is provided with the first electrode 11 for contacting the user's skin to impart the first electric stimulus to the user's skin and the electrode control apparatus 100 that controls the first electric stimulus.
