Description

  The present invention relates to a beauty device that gives a predetermined beauty effect to a user's skin, and more particularly to a device that gives a beauty effect by energization. Note that “low frequency” and “medium frequency” used in the present invention are shown as frequency bands normally used in the field of beauty devices and muscle stimulation devices. Specifically, “low frequency” is from 1 kHz. The small frequency band, “medium frequency”, indicates a frequency band from 1 kHz to 10 kHz. In addition, the term “skin” used in conjunction with “skin” as a target for giving a cosmetic effect in the present invention is treated as synonymous with “skin” not only on the body surface but also on the body surface layer including subcutaneous tissue such as subcutaneous fat. Yes.

  Beauty devices that perform various operations related to predetermined beauty and skin beautification on the skin (skin) of the user's face, etc., are simple functions that are used at home and those that are low output, and are multifunctional that are used for business purposes. Various types are used, including those with high output. Among these beauty devices, the simple ones used at home include those that cool or heat the skin, those that apply suction to the skin, those that apply steam or mist to the skin, and light that irradiates the skin. In general, those that transmit ultrasonic vibrations to the skin, and those that perform iontophoresis by passing a weak current through the skin are commonly used.

  Among these, devices using an iontophoresis method capable of obtaining an excellent effect of deeply penetrating various active ingredients for the skin have been attracting attention in recent years. There are some which are indicated by -237545 gazette and JP, 2005-245521, A.

JP 2005-237545 A JP-A-2005-245521

  Conventional beauty devices are configured as described in each of the above patent documents, including devices that perform such ion introduction, cleansing devices that remove harmful components and waste products accumulated in the skin, In a device that promotes blood circulation and gives a massage effect, a device that gives a skin lifting effect, etc., the skin is energized. The energization of the skin is performed by setting the direction and frequency of the current according to the purpose. In particular, in the case of ion introduction, it is advantageous to execute the energization at a direct current or a low frequency.

  However, when the skin is energized, the lower the frequency, the higher the impedance at the contact point between the device electrode and the skin, so the voltage drop at the time of energization increases at the moment when both contact, and the energization waveform is spiked. Stimulates skin nerve with rush waveform. Moreover, at low frequencies, the time ratio of feeling an electrical signal propagating to the nerve as a stimulus may become longer. For example, when low-frequency energization is performed on the skin by ion introduction, a tingling feeling is added to the skin, etc. In the case of a person with high skin irritation and sensitive skin, it may be easily felt as pain, leading to a frustration in using such a device.

The present invention has been made to solve the above problems, and when energizing the skin, it suppresses the stimulation that is felt as pain by devising the energization waveform, and can be used even by people with sensitive skin, and has excellent cosmetic effects An object of the present invention is to provide a beauty device capable of obtaining the desired value.

The beauty device according to the present invention includes a main body, an electrode disposed on a part of the main body so as to contact the user's skin, and an auxiliary electrode disposed on a portion different from the electrode. And a control unit that adjusts and controls an energization state through the user between the electrode unit and the auxiliary electrode unit, and in the beauty device that performs a predetermined energization operation on the user's skin, the electrode unit and the auxiliary unit A main energization period for performing energization related to beauty between the electrode parts is repeated at a period corresponding to a frequency of 950 to 1850 Hz, and a pulse waveform having a frequency of 2 kHz to 4 kHz is used as an introduction energization period continuous before the main energization period. The energization is executed for 1/3 to 1/2 of the main energization period .

  As described above, according to the present invention, the electrode part disposed on a part of the main body part and brought into contact with the user's skin is energized between the auxiliary electrode part which is also in contact with the user's skin, By controlling the energization state by the control unit, the medium frequency that makes it less likely to feel pain than the low frequency by performing energization with a higher-frequency pulse waveform as the introduction energization period before the main energization period related to the cosmetic operation The shocking stimulus at the start of energization that may be felt as a pain is suppressed to a smaller level than when the energization is started as it is during the main energization period, and the energization state changes from the introduction energization period to the main energization period. Smooth transition makes it possible to suppress the stimulation associated with energization as a whole by reducing the room to feel the stimulation of low-frequency energization, and even for people with sensitive skin and high sensitivity to energization. Pain and Less likely to feel, properly it will be able to use resistance without feeling energized at the frequency given a cosmetic effect, given reasonably good cosmetic effect for any kind of user.

Further, in the beauty device to be used as a reference of the present invention, the control unit executes energization in the main energization period by energization that becomes a pulse waveform of a third frequency higher than the first frequency, as necessary. The second frequency in the introduction energization period is higher than the third frequency.

As described above, according to the beauty device which is a reference of the present invention, the main energization period is energized with a pulse waveform, while the introduction energization period is energized as a pulse with a higher frequency, thereby performing the actual energization in the main energization period. Energizing stimulation can be suppressed and power consumption can be reduced by the amount of high-frequency pulse waveform while ensuring sufficient time, and pain is not easily felt due to energization with a higher-frequency pulse waveform during the introduction energization period. The energization of the main energization period can be started in the state, the skin irritation related to energization can be further suppressed, and the situation of feeling pain can be greatly reduced.

  Further, the cosmetic device according to the present invention, as necessary, so that the control unit approaches the pulse width of the pulse in the introduction energization period to the pulse width of the first pulse in the main energization period as time passes. The duty ratio of the pulse is changed one or more times.

  As described above, according to the present invention, the control unit adjusts and changes the duty ratio of the pulse during the introduction energization period, and lengthens the pulse width during the introduction energization period to increase the pulse width of the first pulse during the main energization period. As a result, it is possible to make a gradual transition from the introduction energization period to the main energization period without greatly changing the pulse width, and to suppress the generation of stimulation associated with the start of energization during the main energization period. The energization of the main energization period can be performed as it is, and both high beauty effects and pain suppression can be achieved.

In addition, in the beauty device to be used as a reference of the present invention, if necessary, the control unit may make the second frequency in the introduction energization period approach the third frequency in the main energization period as time passes. Or it is changed several times.

As described above, according to the beauty device that is a reference of the present invention, the control unit adjusts and changes the pulse frequency during the introduction energization period in the middle of the period, and lowers the pulse frequency to approach the first pulse frequency of the main energization period. By doing so, it is possible to make a gradual transition from the introduction energization period to the main energization period without greatly changing the pulse frequency, suppressing the occurrence of stimulation associated with the start of energization during the main energization period, and making it difficult to feel the energization stimulus. By energizing during the energization period, it is possible to achieve both a high cosmetic effect and pain suppression.

  In addition, in the beauty device according to the present invention, as necessary, the control unit changes the amplitude of the pulse in the introduction energization period from the initial amplitude at the start of the introduction energization period with the passage of time in the main energization period. It is changed so as to gradually approach the amplitude of.

  Thus, according to the present invention, the amplitude of the pulse in the introduction energization period is gradually increased from the start of the introduction energization period to approach the amplitude of the energization waveform in the main energization period. Since the skin does not grow from the beginning and the skin is less likely to feel energization, the stimulation by the medium-frequency energization that is difficult to feel as pain is further suppressed, and energization can be started without feeling uncomfortable, improving the quality in terms of usability As well as improving, it will be able to accept energization without a sense of resistance, and will encourage the use of users with more sensitive skin.

(First embodiment of the present invention)
Hereinafter, a beauty device according to a first embodiment of the present invention will be described with reference to FIGS.
In each of the drawings, the cosmetic device 1 according to the present embodiment is used for energization related to beauty on the skin (skin) 50 disposed near the end of the main body 11 and the main body 11 held by the user. In the body portion 11, an auxiliary electrode portion 11 c disposed in a grip portion by the user in the body portion 11, a holding portion 14 that holds the porous covering 13 with respect to the electrode portion 12, and the body portion 11. It is a structure provided with the control part 15 which is arrange | positioned and adjusts and controls the electricity supply state via the user between the electrode part 12 and the auxiliary electrode part 11c.

  The body portion 11 has the electrode portion 12 disposed near one end, while the predetermined length range on the other end side is a thickness suitable for a user to hold the device by holding it by hand during use. The grip portion 11a is formed in a shape in which the longitudinal direction of the grip portion 11a and the front direction of the electrode portion 12 are inclined by a predetermined angle, and an electric circuit such as the control portion 15 or a battery as a power source is provided inside. (Illustration is omitted).

  Further, on the side surface portion near the other end side of the main body portion 11, there is disposed an operation portion 11 b that receives a user's input operation and switches the cosmetic operation ON / OFF, the type of operation, the strength, and the like. An auxiliary electrode portion 11c made of a conductive member and connected to the control portion 15 is disposed on the back side of the main body portion 11 where the electrode portion 12 is not provided. The electrode part 11c comes into contact. The main body 11 can incorporate a vibration source such as a vibrator, and can add vibration to the skin 50 along with energization to enhance the cosmetic effect.

  Furthermore, between the holding part 11a and the electrode part 12 on the front side of the main body part 11 with the electrode part 12, the holding part 14 can be tilted with respect to the main body part 11 and the tilting central axis can be moved up and down. It is a configuration to be installed. The attachment portion of the holding portion 14 in the main body portion 11 is completely cut off from the inside of the main body portion 11 and can prevent the liquid agent for ion introduction and the like from entering the inside.

As long as the auxiliary electrode portion 11 c is different from the electrode portion 12, the auxiliary electrode portion 11 c may be separated from the main body portion 11, and is not limited to the configuration directly provided on the main body portion 11. In this case, for example, a lead wire connected to the control unit 15 is led out from the main body unit 11 with respect to a separate auxiliary electrode unit, and the tip of the lead wire is attached to hold the auxiliary electrode unit by hand. Or by stepping with bare feet, a conductive state can be obtained.

  The electrode portion 12 is made of a conductive material such as metal, has a substantially planar portion that can come into surface contact with the skin 50, and has a curved upper edge portion 12a that protrudes from the upper portion of the main body portion 11. The skin 50 is brought into contact directly or via the porous covering 13 such as a cotton puff, and the skin 50 is subjected to a cosmetic operation related to energization including ion introduction. This electrode part 12 is electrically connected to the control part 15 in the main body part 11, and is configured to be able to be energized via the user's body with the auxiliary electrode part 11c in the grip part 11a. .

  For energization, the control unit 15 applies a voltage between the electrode unit 12 and the auxiliary electrode unit 11c so that energization can occur, and the porous covering is impregnated with a liquid agent such as skin lotion containing an electrolyte component. 13 or directly, when the electrode part 12 contacts the skin 50 such as the face and the auxiliary electrode part 11c comes into contact with the palm or the finger of the hand having the grip part 11a, the electrode part 12 and the auxiliary electrode part 11c Is a mechanism that is energized through the user's body. In this case, the human body becomes a conductor. The electrode portion 12 and the auxiliary electrode portion 11c are sufficiently separated from each other, so that a hand or the like that touches the auxiliary electrode portion 11c accidentally contacts the electrode portion 12 so that energization does not occur.

  With the energization of the skin 50 in contact with the electrode part 12, an ionic active ingredient contained in a liquid such as lotion that has been applied to the skin surface in advance or has been infused into the porous coating 13, This is a mechanism capable of executing ion introduction (iontophoresis) introduced into the skin by ion movement based on current from the control unit 15. Since the ion introduction method itself is known, a detailed description thereof will be omitted.

  Further, as cleansing during face washing, it is possible to obtain a state in which dirt components such as charged wastes are transferred from the skin side to the electrode part 12 side by energization and taken into the porous coating 13.

  The porous covering 13 is used as a cover for covering the electrode portion 12 by forming cotton fibers processed by degreasing, such as cut cotton and cotton puff, into a non-woven sheet larger than the electrode portion 12. It has the property that it can be absorbed and retained as it is. In addition, as long as this porous covering body 13 can be impregnated with skin lotion or the like and has a flexible porous soft sheet shape, those other than cotton can be used.

  The electrode portion 12 is desirably made of a material that is stable with respect to energization, such as titanium, in terms of ion introduction and the like. That is, if the electrode part 12 is made of a plated surface of chromium or the like, metal ions are eluted on the surface of the electrode part 12 by electrolysis when ions are introduced, and the eluted metal ions have an adverse effect on the skin. However, if titanium having high stability is used on the electrode surface, metal ions of titanium are not eluted by electrolysis at the electrode portion 12 even when energized, and can be used safely. The electrode surface material is preferably pure titanium, but may be a titanium compound. In addition to using metal such as gold in addition to titanium, it may have a structure formed by attaching a conductor such as metal to the surface of an elastic body such as conductive resin, conductive rubber, or rubber, or arranging a thin film of conductor. it can.

  The holding portion 14 is formed as a substantially annular body made of a material that does not easily deform, and is supported by the main body portion 11 so as to be tiltable and vertically movable with an end portion as a tilting central axis, and a portion near the electrode portion 12 in the main body portion 11. It is a structure made movable from the position which surrounds to the position which becomes a protrusion state in the front side of the electrode part 12. In addition, the holding portion 14 is configured to be able to maintain a state in which the tilting central axis portion is biased toward the gripping portion 11 a side, that is, downward, with respect to the main body portion 11 and is located around the vicinity of the electrode portion 12 of the main body portion 11.

  The opening portion of the holding portion 14 is slightly larger than the shape of the electrode portion 12 and the portion in the vicinity of the electrode portion 12 of the main body portion 11, and when the holding portion 14 is tilted, the electrode portion 12 is relatively held by the holding portion 14. It will be in the state which goes in and out. When the holding part 14 is positioned around the vicinity of the electrode part of the main body part 11, the electrode part 12 protrudes forward from the opening part of the holding part 14, and when the electrode part 12 is applied to the skin 50, The holding part 14 is in a state where it is difficult to touch the skin 50.

  The holding part 14 is set to a position where the holding part 14 protrudes to the front side of the electrode part 12, the porous covering 13 is sandwiched between the holding part 14 and the electrode part 12, and the holding part 14 is further inserted into the main body part 11. And the upper edge 12a of the electrode part 12 is moved up and down so that it is positioned around the vicinity of the electrode part 12 of the main body part 11, the peripheral part of the porous covering 13 is held by the holding part 14 The porous covering 13 is sandwiched between the main body 11 and the body 11 so that the porous covering 13 is not easily detached, and the porous covering 13 is held on the surface of the electrode portion 12. And the holding | maintenance part 14 cannot move depending on the magnitude | size and thickness of the porous coating | coated body 13 by being able to move up and down with respect to the main-body part 11, and the holding | maintenance part 14 is around the electrode part 12 vicinity part of the main-body part 11. The porous covering 13 can be reliably held on the surface of the electrode part 12 only by being positioned.

  The control unit 15 is built in the main body unit 11 and controls energization between the electrode unit 12 and the auxiliary electrode unit 11c in response to an input operation to the operation unit 11b by the user. This control unit 15 sets a mode of energization operation for each cosmetic use. In this embodiment, a cleansing mode for removing harmful components and waste products accumulated in the skin, and a lotion or the like in the deep part of the skin. There are three modes: an iontophoresis mode for penetrating active ingredients, and a blood circulation promotion mode for promoting blood circulation of the skin by switching the electrode polarity during energization.

  In the cleansing mode, the iontophoresis mode, and the blood circulation promotion mode, although the point where the electrode portion 12 and the auxiliary electrode portion 11c are energized is common, the direction and waveform of the current during energization are different. The blood circulation promotion mode has two modes, massage and lifting, with the same energization waveform but different energization times. The massage mode mainly promotes blood circulation of the skin and maintains its elasticity by energization after the cleansing mode. On the other hand, the lifting mode is intended to bring about the effect of raising the skin while mainly promoting the blood circulation of the skin and fixing and penetrating the active ingredient by energization after the iontophoresis mode.

  Switching between these energization modes is performed based on a user input operation to the mode switch 11d of the operation unit 11b. When the user first operates the mode changeover switch 11d immediately after the power is turned on, the control unit 15 is in a state where it can execute any one of the cleansing mode, the iontophoresis mode, and the blood circulation promotion mode. In addition, each mode may be continuously executed in a predetermined order (for example, cleansing, massage, iontophoresis, and lifting). In that case, it is preferable that the controller 15 temporarily stops the energization operation of each mode while notifying the end of each mode by turning on a display lamp or the like, and then transitions to the next mode after a predetermined time has elapsed.

  Further, the control unit 15 adjusts the strength of the current flowing through the user's skin by energization when the electrode unit 12 and the auxiliary electrode unit 11c are energized corresponding to each operation mode. May be. In this case, the adjustment is performed based on a user's input operation to a strength change switch provided separately in the operation unit 11b.

The control unit 15 is a computer having a CPU, a memory, an input / output interface, and the like as its hardware configuration, and is a mechanism that causes the computer to operate as a control means by a program stored in the memory or the like. The computer constituting the control unit 15 is usually implemented as a microcomputer in which a CPU, a memory, a ROM, and the like are integrally formed.

  Furthermore, the control unit 15 performs the energization between the electrode unit 12 and the auxiliary electrode unit 11c, the main energization period P1 for performing energization related to beauty, and the introduction energization period continuous before the main energization period P1. P0 is set (see FIG. 8). In the main energization period P1, energization with an energization waveform corresponding to each mode of energization operation is repeated at a cycle (for example, about 12 to 1000 ms) corresponding to a first frequency that is a low frequency (less than 1 kHz), and is used for beauty. The effect by energization corresponding to each mode is obtained. Among the energization modes, in the cleansing mode and the ion introduction mode, the energization in the main energization period P1 is an energization having a pulse waveform with a third frequency (for example, about 950 to 1850 Hz) higher than the first frequency. It is executed by.

  In the blood circulation promotion mode, the energization in the main energization period P1 in the massage mode is a waveform in which each pulse of positive polarity and negative polarity appears in the same pulse width with a predetermined pause time between 100 ms (see FIG. 14). It is done to become. Further, energization in the main energization period P1 in the lifting mode is performed so that each pulse of positive polarity and negative polarity appears in the same pulse width with a predetermined pause time between 1000 ms (see FIG. 15). .

  On the other hand, the introduction energization period P0 is a second frequency that is a medium frequency (1 to 10 kHz) for a predetermined time shorter than the main energization period P1, for example, 1/3 to 1/2 of the main energization period P1. For example, energization having a pulse waveform of about 2 to 4 kHz is executed. Among the energization modes, in the cleansing mode and the ion introduction mode executed by energization having a pulse waveform of the third frequency in the main energization period P1, the second frequency in the introduction energization period P0 is at least the main energization. As a frequency higher than the third frequency in the period P1, the stimulation itself caused by energization appears in the introduction energization period P0 smaller than the main energization period P1.

  The control unit 15 increases the pulse duty ratio once to increase the pulse width of the pulse in the introduction energization period P0 so as to approach the pulse width of the first pulse in the main energization period P1 in the middle of the period. The pulse width is increased (see FIG. 8). More specifically, the pulse width of the first pulse in the main energization period P1 is 0.18 ms (pulse frequency about 1.85 kHz), the pulse frequency in the introduction energization period P0 is 4 kHz, and the initial duty ratio is 1: 1. In this case, the initial pulse width is 0.125 ms, but by changing the duty ratio to 2: 1 at the time when 1/3 of the introduction energization period P0 has elapsed, the pulse width becomes 0.167 ms, and the main energization period It approaches the pulse width of P1. As a result, the difference in pulse width between the introduction energization period P0 and the main energization period P1 is reduced, and the transition from the energization state of the introduction energization period P0 to the energization state of the main energization period P1 can be performed more smoothly. By reducing the possibility of energization stimulation at the time of transition to period P1, it is possible to efficiently perform energization related to beauty while maintaining a state where it is difficult to feel the stimulation of energization, achieving both high beauty effects and pain suppression it can.

  In the introduction energization period P0, the change of the duty ratio is not limited to once, and the pulse width of the pulse gradually approaches the pulse width of the first pulse in the main energization period P1, that is, gradually. The duty ratio of the pulse may be changed a plurality of times so as to increase, and the stimulation of energization can be made difficult to feel as the change in the pulse width becomes smooth.

In addition, in the main energization period P1 in the cleansing mode or the ion introduction mode, the control unit 15 gives a sufficient pulse rise time when generating each pulse as shown in FIG. 9 and FIG. By making it gentle and making the shape of the pulse waveform slightly curved, the voltage level of the pulse gradually rises and prevents suddenly reaching the coherent voltage that senses the electricity of the living body, thereby Stimulation is suppressed, which is preferable. In particular, in the case of a beauty device, the discomfort caused by energization can be suppressed because it is used for the skin of a sensitive face, which is effective.

  Further, as shown in FIG. 9 and FIG. 12, the control unit 15 has a main energization period P1 in the cleansing mode and the ion introduction mode, and after a plurality of pulses of the same polarity (for example, positive) in the energization waveform of one cycle, By outputting a pulse of reverse polarity (for example, negative) through a rest period, the charged state in the body can be released, and the waveform of energization in the body is close to the pulse waveform output from the electrode, that is, the pulse The pulse waveform is surely close to 0 potential later, and the effect of electrification on the user's skin is prevented by preventing the waveform from being distorted so that the voltage cannot be sufficiently lowered after the pulse due to the influence of charging. It can be given more appropriately and is preferable.

  In addition, the control unit 15 detects a state in which the electrode unit 12 is in contact with the skin 50 and can be energized between the electrode unit 12 and the auxiliary electrode unit 11c through a body or the like, and relates to beauty. It is a structure provided with the function to start electricity supply. In order to determine the energization possible state, if any pulse can be output from one electrode, each electrode portion is in contact with the skin because this pulse is detected by the other electrode. Therefore, when this pulse is no longer detected by the other electrode, it can be determined that energization is impossible. Then, energization related to beauty is stopped when energization is impossible, and energization is resumed when energization is possible again.

  Whether a pulse for detection is output from the electrode unit 12 or the auxiliary electrode unit 11c differs depending on each mode, but the pulse output from one electrode passes through the human body to the other electrode. Thus, it is necessary to drop the potential of the electrode on which no pulse is output to the GND level. For example, when a pulse is output from the electrode unit 12, the potential of the auxiliary electrode unit 11c is dropped to the GND level. On the other hand, when outputting a pulse from the auxiliary electrode part 11c, the electric potential of the electrode part 12 is dropped to the GND level. The frequency of the pulse for detection is preferably set to a medium frequency or higher in terms of stimulation to the skin.

  Next, the energization operation state of the beauty device according to the present embodiment will be described. As a premise, it is assumed that the beauty device 1 is activated by the user operating the power switch 11e of the operation unit 11b, and the user is in a state where the user holds the grip unit 11a and is directed to the skin site where the electrode unit 12 is desired to be used. If the operation mode is selected and input by the user, the control unit 15 enters a state in which execution of each operation mode can be started.

  When cleansing, the user first tilts the holding part 14 so that it protrudes to the front side of the electrode part 12 (see FIG. 4A), and soaks in the wiping lotion containing the electrolyte component. The porous covering 13 is positioned in front of the electrode part 12 and is sandwiched between the holding part 14 and the electrode part 12 (see FIG. 5A). Further, the holding part 14 is moved upward while tilting the holding part 14 with respect to the main body part 11 (see FIG. 5B) so that the upper part of the holding part 14 gets over the upper edge part 12a of the electrode part 12, and then When the holding part 14 is lowered by the urging force on the back side from the electrode part 12 (see FIG. 6A) and is positioned around the vicinity of the electrode part of the main body part 11, the holding part 14 is interposed between the holding part 14 and the main body part 11. The porous coating 13 is held and fixed on the surface of the electrode portion 12 by sandwiching the peripheral portion of the porous coating 13, and the electrode portion 12 covered with the porous coating 13 is an opening portion of the holding portion 14. A more protruding state is obtained (see FIG. 6B).

In a state where the porous covering 13 is covered by the holding portion 14 while covering the electrode portion 12, the end of the porous covering 13 is along the side surface of the main body 11 and is porous outward from the main body 11. When the end of the porous covering 13 protrudes, for example, when the user points the electrode portion 12 toward the skin near the eyes, the end of the porous covering 13 enters the eyes, or the operation related to cosmetics It can be prevented from becoming an obstacle.

  When the user operates the mode selector switch 11d of the operation unit 11b to select the cleansing mode, the control unit 15 first outputs a detection signal. In the state where the electrode part 12 is separated from the skin, since the circuit between the electrode part 12 and the auxiliary electrode part 11c is not a closed circuit through the body, there is no energization, but the electrode part 12 is attached to the porous covering 13. When the skin is brought into close contact with the skin 50, energization through the body and the skin lotion in the porous covering body 13 becomes possible, and when this state is detected by receiving the output detection signal, the control unit 15 relates to cleansing. In the energization state, first, energization is executed as a waveform of a repetitive pulse of medium frequency in the introduction energization period P0. In the introduction energization period P0, the pulse width of the pulse becomes longer due to the duty ratio change in the middle of the period by the control unit 15, and the pulse width of the first pulse in the main energization period P1 becomes closer to the initial value.

  Thereafter, the introduction energization period P0 shifts to the main energization period P1, and in the main energization period P1, the control unit 15 performs energization having a pulse waveform (see FIG. 8 and FIG. 9) whose period gradually changes. 12 and the auxiliary electrode portion 11c, and the charged fine dirt components on the skin surface and in the interior (cosmetic components that could not be removed, tobacco smoke components, aging skin, etc.) are attracted to the electrode portion 12. By shifting from the skin side to the porous coating 13 side and entering the dirt component into the porous coating 13, the skin dirt can be removed by suction (see FIG. 7). For the part of the skin 50 to be cleansed, such as the boundary between the nose and cheek, the upper edge portion 12a of the electrode portion 12 that protrudes from the upper portion of the main body portion 11 and is curved is used. Thus, the electrode portion 12 can be reliably brought into contact with the concave portion of the skin 50 through the porous covering 13, and cleansing can be performed without unevenness (see FIG. 10).

  While the energization consisting of the introduction energization period P0 and the main energization period P1 in the cleansing mode is in close contact with the skin 50 via the porous covering 13, the period corresponding to the first frequency which is a low frequency. Thus, the entire energization waveform is obtained by superimposing a pulse waveform having a higher frequency on the low frequency waveform.

  If the electrode 12 is moved little by little on the skin while the porous covering 13 is in contact with the skin 50, the target position of the dirt removal can be changed in the energized state, but this removal operation can be interrupted or removed. When the electrode unit 12 is separated from the skin 50 to change the frequency, the control unit 15 determines that the electrode unit 12 is separated from the skin because the pulse accompanying the energization cannot be detected by the other electrode. Stop. When the energization is stopped in this way, the detection signal is output again. When the electrode unit 12 is brought into close contact with the skin 50 through the porous covering 13 again, the energized state can be detected by receiving a detection signal, and the control unit 15 shifts to the energized state related to cleansing. And resume energization. When cleansing is completed completely, the user may switch the operation mode to another by using the operation unit 11b or turn off the power.

  After this cleansing mode is finished, the holding part 14 is tilted from the peripheral position of the electrode part vicinity of the main body part 11 to the front side of the electrode part 12 to protrude from the main body part 11, and the porous state in which the holding state is released The covering 13 is removed and the electrode part 12 is cleaned. In addition, the user cleans the face and removes the dirt remaining on the skin.

When ion introduction is performed, the user sets the holding portion 14 to the front side of the electrode portion 12 as described above, and the porous covering 13 impregnated with the protective lotion containing the electrolyte component is used as the electrode. It is set to be disposed between the holding part 14 and the electrode part 12 so as to be positioned in front of the part 12. Further, while tilting the holding portion 14 with respect to the main body portion 11, the holding portion 14 is moved upward so that the upper portion of the holding portion 14 gets over the upper edge portion 12 a of the electrode portion 12, and the holding portion 14 is moved to the main body portion 11. Positioned around the electrode portion, the porous coating 13 is sandwiched between the holding portion 14 and the main body 11, and the porous coating 13 is held and fixed on the surface of the electrode portion 12. In this case, after the porous covering 13 is held and fixed on the surface of the electrode part 12, lotion may be soaked into the porous covering 13.

  When the user operates the mode selector switch 11d of the operation unit 11b to select the ion introduction mode, the control unit 15 first outputs a detection signal. In a state in which the electrode part 12 is separated from the skin 50, since the circuit between the electrode part 12 and the auxiliary electrode part 11c is not closed through the body, there is no energization.

  When the electrode unit 12 is brought into close contact with the skin 50 through the porous covering 13, the energization through the body and the lotion in the porous covering 13 becomes possible, and this state is obtained by receiving the output detection signal. When detected, the control unit 15 shifts to an energization state related to ion introduction having a polarity opposite to that in the cleansing case, and first, energization is performed as a waveform of a repetitive pulse of medium frequency as the introduction energization period P0. In the introduction energization period P0, the pulse width of the pulse becomes longer due to the duty ratio change in the middle of the period by the control unit 15, and the pulse width of the first pulse in the main energization period P1 becomes closer to the initial value.

  Thereafter, the introduction energization period P0 shifts to the main energization period P1, and in the main energization period P1, the control unit 15 assists the electrode unit 12 with energization having a pulse waveform (see FIG. 12) whose period gradually changes. It is performed between the electrode parts 11c, and the ionic active ingredient (provitamin C etc.) in the lotion is transferred to the skin side by the current flowing through the porous covering 13, and the ions are easily penetrated by the current. The active ingredient quickly penetrates into the skin (see FIG. 11). As in the case of cleansing, the upper edge portion 12a of the electrode portion 12 is reliably brought into contact with the surface of the skin 50 through the porous covering 13 on the concave portion such as the boundary between the nose and the cheek. Thus, ion introduction can be performed without bias.

  Also in this ion introduction mode, while the energization consisting of the introduction energization period P0 and the main energization period P1 is in close contact with the skin 50 via the porous covering 13, the first frequency which is a low frequency is obtained. The entire energization waveform is a low-frequency waveform superimposed with a pulse waveform having a higher frequency than this.

  If the electrode 12 is moved little by little on the skin while the porous covering 13 is in contact with the skin 50, the ion introduction target position can be changed in the energized state, but the ion introduction is interrupted or the introduction position is changed. When the electrode unit 12 is separated from the skin 50 in order to greatly change, the pulse accompanying the energization cannot be detected by the other electrode, so that the control unit 15 determines that the electrode unit 12 is separated from the skin and relates to the ion introduction. Stop energization. When the energization is stopped in this way, the detection signal is output again. When the electrode unit 12 is brought into close contact with the skin 50 through the porous covering 13 again, the energized state can be detected by receiving a detection signal, and the control unit 15 enters the energized state related to ion introduction. Move on and resume energization. When ion introduction is completed completely, the user may switch the operation mode to another by using the operation unit 11b or turn off the power.

  After completion of this ion introduction mode, the holding part 14 is tilted from the peripheral position of the electrode part vicinity of the main body part 11 to the front side of the electrode part 12 so as to protrude from the main body part 11, and the porous state released from the holding state. The material covering 13 may be removed and the electrode portion 12 may be cleaned as necessary.

  When energizing the skin such as massage or lifting, the porous coating 13 is not used, and the holding portion 14 is positioned around the portion near the electrode portion of the main body portion 11 on the back side of the electrode portion 12, When the part 12 is brought into contact with the skin, the holding part 14 is not in an obstacle state. At the same time, apply a lotion or cream to the skin as necessary.

When the user operates the mode switch 11d of the operation unit 11b to select the massage mode or the lifting mode, the control unit 15 first outputs a detection signal. In the state where the electrode part 12 is separated from the skin, since the circuit between the electrode part 12 and the auxiliary electrode part 11c is not closed via the body, there is no energization.

  When the electrode unit 12 is brought into close contact with the skin 50, energization through the body becomes possible, and when this state is detected by receiving the output detection signal, the control unit 15 shifts to an energization state related to massage or lifting. First, energization is executed as a waveform of a repetitive pulse of medium frequency as the introduction energization period P0. In the introduction energization period P0, the pulse width of the pulse becomes longer due to the duty ratio change in the middle of the period by the control unit 15, and the pulse width of the first pulse in the main energization period P1 becomes closer to the initial value.

  Thereafter, the introduction energization period P0 shifts to the main energization period P1. In the main energization period P1, in the massage mode, the control unit 15 causes the positive and negative pulses to have a predetermined pause time between 100 ms. The energization to be a low frequency waveform (see FIG. 14) appearing at the same pulse width is performed between the electrode portion 12 and the auxiliary electrode portion 11c, and the energization state is established between the electrode portion 12 and the auxiliary electrode portion 11c via the body, The skin 50 is energized at a low frequency (see FIG. 13), activates the skin 50 to give a massage effect, and promotes blood circulation. Further, in the lifting mode, the control unit 15 energizes the low-frequency waveform (see FIG. 15) in which each positive and negative pulse appears with the same pulse width with a predetermined pause time between 1000 ms. And the energized state is established through the body between the electrode unit 12 and the auxiliary electrode unit 11c, and the skin 50 is energized at a low frequency (see FIG. 13) to promote the penetration of the active ingredient into the skin 50 and to the skin. It will give the effect of lifting by applying tension.

  Also in these massage modes and lifting modes, the energization consisting of the introduction energization period P0 and the main energization period P1 is repeated at a cycle corresponding to the first frequency, which is a low frequency, while the electrode portion 12 is in close contact with the skin 50. Will be.

  When the electrode part 12 is moved little by little on the skin while being in contact with the skin 50, the target position of energization can be changed, but the electrode part 12 is separated from the skin 50 in order to interrupt the energization or change the energization position. When the pulse accompanying energization cannot be detected by the other electrode, the control unit 15 determines that the electrode unit 12 is separated from the skin, and stops energization related to massage or lifting. When the energization is stopped in this way, the detection signal is output again. When the electrode unit 12 is brought into close contact with the skin 50 again, the energized state can be detected by receiving a detection signal, and the control unit 15 shifts to an energized state related to massage or lifting and resumes energization. To do. Further, when the user switches the function to another one with the operation unit 11b or turns the power off, the energization is completely terminated.

  As described above, in the beauty device according to the present embodiment, the electrode unit 12 disposed at one end of the main body unit 11 and brought into contact with the user's skin is energized between the gripped auxiliary electrode unit 11c. In the control of the energization state by the control unit 15, the energization is performed with a pulse waveform having a higher frequency as the introduction energization period P0 before the main energization period P1 related to the cosmetic operation. Starting energization at a medium frequency that is difficult to feel, the shocking stimulus at the start of energization, which may be felt as pain, can be suppressed to be smaller than when the energization in the main energization period P1 is started as it is, and the energized state is By smoothly transitioning from the introduction energization period P0 to the main energization period P1, there is less room to feel the stimulation of low-frequency energization, and the stimulation associated with energization can be suppressed as a whole, and the skin is weak and highly sensitive to energization. Even people, less likely to feel the stimulus according to the current as pain, properly will be able to use resistance without feeling energized at the frequency given a cosmetic effect, given the excellent cosmetic effect for any kind of user.

In the beauty device according to the embodiment, the holding portion 14 is attached to the main body portion 11 so as to be tiltable and movable up and down and is integrally handled. However, the present invention is not limited to this, and the porous covering is used as the electrode portion. If it can be held by pressing along the body, the holding part has a separate structure that is not integrated with the main body from the beginning, and only when a porous coating is used, such as cleansing or iontophoresis. It can also be set as the structure which makes it possible to hold | maintain a porous coating body by attaching to a part. In this case, it is preferable that the holding part is made of an elastically deformable material so that the holding part is engaged with and attached to the main body part with some deformation, from the viewpoint of simplifying the structure.

  Further, in the beauty device according to the embodiment, when ion introduction is performed, the porous covering body 13 soaked with the protective lotion is held so as to cover the electrode portion 12, and the porous covering body 13 includes The active ingredient contained in the skin lotion is transferred to the skin and the active ingredient penetrates into the skin. In addition to this, the electrode part is in direct contact with the skin that has been applied with protective lotion. As an energized state through the body, the active ingredient contained in the skin lotion can be permeated into the skin with an electric current flowing from the electrode portion to the skin. The energization is performed as a waveform of a repetitive pulse of medium frequency as the energization period P0, and then the main energization period P1 is started, and the pain due to energization is made difficult to be felt. Electricity flowing to In transitions the ions of the active ingredient of the skin surface to the skin side, the skin ions are in a state of easy penetration of the current, the active ingredient is provided reliably cosmetic effects deeply rooted.

  Further, in the beauty device according to the embodiment, the control unit 15 increases the pulse width by changing the duty ratio of the pulse once in the middle of the introduction energization period, and in the main energization period. The control is performed so as to approach the pulse width of the first pulse. However, the control unit 15 is not limited to this, and when the user is resistant to energization stimulation and hardly feels pain, the control unit 15 performs the introduction energization period P0. The pulse width of the pulse is not changed in the middle of the period but can be kept as it is, and the energization with the same pulse width can be continued until the main energization period P1 is started, thereby simplifying the control.

(Second embodiment of the present invention)
In the first embodiment, in each energization operation mode, control is performed so that the pulse width of the pulse in the introduction energization period P0 approaches the pulse width of the first pulse in the main energization period P1 in the middle of this period. The unit 15 performs control to change the duty ratio of the pulse and increase the pulse width. However, the present invention is not limited to this, and as shown in FIG. 16, the pulse width in the introduction energization period P0 is as follows. As it is, the pulse frequency in the introduction energization period P0, that is, the second frequency may be changed one or more times so as to approach the third frequency in the main energization period P1.

  More specifically, the initial pulse frequency in the introduction energization period P0 is 4 kHz, while the pulse frequency of the first pulse in the main energization period P1 is about 1.85 kHz (pulse width 0.18 ms). The pulse frequency is changed to 2.67 kHz at the time when 2/5 of the energization period P0 has elapsed to approach the pulse frequency of the main energization period P1. The initial duty ratio of the introduction energization period P0 is 1: 1 and the initial pulse width is 0.125 ms. However, when the pulse frequency is changed at the time of 2/5 elapse of the introduction energization period, the duty ratio becomes 1 : By changing to 2, the pulse width does not change before and after the change of the pulse frequency.

  Thus, by reducing the difference in pulse frequency between the introduction energization period P0 and the main energization period P1, the main energization period P1 is changed from the energization state of the introduction energization period P0 as in the case of changing the pulse width in the first embodiment. Energization related to beauty while maintaining a state where it is difficult to feel energization stimulation by reducing the possibility of energization stimulation at the time of transition from the introduction energization period P0 to the main energization period P1. Can be carried out efficiently, and both a high beauty effect and pain suppression can be achieved.

(Third embodiment of the present invention)
In the first embodiment, although the pulse width of the pulse in the introduction energization period P0 is changed in the middle of each energization mode, the amplitude of the pulse is not particularly changed. In the third embodiment, as shown in FIG. 17, the control unit 15 gradually increases the amplitude of the pulse in the introduction energization period P0 from the amplitude minimum value at the start of the introduction energization period P0, and finally It can also be changed to approximate the amplitude of the pulse during the energization period.

  In this way, in addition to conducting energization with a medium-frequency pulse with a small stimulus related to energization in the introduction energization period P0, the amplitude of the pulse is gradually increased from the start of the introduction energization period, and the amplitude of the pulse is increased from the beginning of the introduction energization period. By preventing the living body from feeling the level of electricity and reducing the degree of feeling the energization in the introduction energization period P0 as a stimulus, the stimulation related to the energization at the start of energization is further suppressed, and the energization related to beauty is performed. It is possible to improve the quality in terms of feeling of use by reducing the pain and discomfort caused by energization of the user while ensuring a state where it can be executed efficiently.

  In the main energization period P1 in the cleansing mode or the ion introduction mode, the control unit 15 does not set the amplitude of the pulse to a constant amplitude from the start of the period, but sets a lower amplitude at the start of the period. It can be gradually increased so as to reach the maximum amplitude value, and in combination with the amplitude control in the introduction energization period P0, the feeling of stimulation related to energization can be more reliably suppressed. In this case, it is assumed that the final value of the amplitude of the pulse in the introduction energization period P0 matches the amplitude of the first pulse in the main energization period P1.
