As described above, in the beauty tool of Patent Document 2, a cotton mat impregnated with a cosmetic solution is attached to the head in the putting mode, and the cosmetic solution is permeated into the skin while supplying a positive current to the skin surface. At the same time, the LEDs are irradiated with visible light on the skin surface to activate the fibroblasts in the dermis layer. However, even when visible light is emitted from the LED with the cotton mat attached to the head, the visible light is blocked by the cotton mat and does not easily reach the skin surface. On the other hand, when the visible light is emitted with the cotton mat removed from the head, light stimulation can be applied to the skin surface, but the unadjusted visible light emitted from the LED is directly emitted from the acrylic resin window plate. Therefore, the illuminance of visible light on the skin surface tends to be uneven. Specifically, although the illuminance at the center of the window plate facing the LED is high, it is inevitable that the illuminance at the peripheral portion of the window plate is low, and the light at the high illuminance part gets into the eyes and causes discomfort. It may end up.

By screwing a screw 29 inserted through the front end wall of the head support 15 into the boss 28, the heater holder 25 Are integrated with the head support 15. An elastic ring 30 made of silicone rubber is provided on the front surface of the heater holder 25, and the ring-shaped heater 31 is pressed against the skin stimulating body 3 by this ring 30. Between the heater holder 25 and the skin stimulating body 3, a spring 32 for supplying a positive polarity or negative polarity current is arranged. The spring 32 is connected to the control board 7 via the electrode lead 53, which is not shown in FIG.

The light source 26 is a so-called three-primary-color white LED including three bullet-shaped LEDs, a red LED 26R, a green LED 26G, and a blue LED 26B, which individually emit the three primary colors of light. When three LEDs are made to emit light at the same time, visible light close to natural light can be emitted, and when three LEDs are made to emit light individually, red light, green light and blue light can be emitted. When the red LED 26R and the green LED 26G are made to emit light at the same time, yellow light can be emitted, and when the red LED 26R and the blue LED are made to emit light at the same time, purple light can be emitted. By adjusting the current value supplied to each of the LEDs 26R, 26G, and 26B, the intensity (illuminance) of each light can be increased in proportion to the current value.

The skin stimulating body 3 is made of a press-molded product in the shape of a round cap made of a titanium plate material, and a flange-shaped mounting wall 34 is formed overhanging around the inner opening edge. A circular window opening 35 for exposing the light guide 27 is formed in the center of the stimulating surface 3a on the front surface of the skin stimulating body 3. As shown in FIG. 4, when the connecting cylinder wall 18 of the head case 16 is fastened to the mounting seat 14 with the screw 22, the O-ring (second seal body) 36 mounted on the mounting wall 34 is attached to the mounting wall 34 and the head. It is sandwiched by the stepped portion 20 of the case 16 and elastically deformed to seal the gap between the front opening 19 and the peripheral wall of the skin stimulating body 3.

As shown in FIG. 1, the light source 26 and the window opening 35 of the skin stimulator 3 face each other through the light adjustment space S, and the light guide 27 is arranged in the light adjustment space S. The light guide 27 includes a front light guide 38 that also serves as a holder for the light source 26, and a rear light guide 39 that is arranged between the front light guide 38 and the skin stimulator 3. The front light guide 38 is formed of a translucent plastic material, and is a light source for mounting the flange-shaped base portion 40 and the LEDs 26R, 26G, and 26B previously provided on the front surface of the base portion 40. The holder 41 and the support cylinder 42 that is provided on the front side of the holder 41 and supports the rear light guide 39 are integrally provided. On the rear surface of the light source holder part 41, a mounting recess (mounting part) 43 for receiving the light emitting parts of the LEDs 26R, 26G, and 26B is formed. The base portion 40 is fastened and fixed to the seat wall of the mounting seat 14 with screws 22 together with the connecting cylindrical wall 18 of the head case 16 described above.

The rear light guide 39 is formed of a light-transmissive plastic material including a filler 65 (see FIG. 6) having a light diffusing function, and has a disc-shaped light guide portion 45 and a front surface of the light guide portion 45. The irradiating unit 46 provided and the connecting cylindrical unit 47 having a round tubular shape protruding from the rear surface of the light guiding unit 45 are integrally provided. As the filler 65, a material having a refractive index different from the refractive index of the latter-stage light guide 39 may be used, and crystalline silica, aluminum hydroxide, fine particles of quartz glass, metal fine particles, micro bubbles, or the like can be applied, but high-level light is used. Fine particles of quartz glass capable of exhibiting a diffusing action are preferred. An irradiation surface 48 is formed on the front surface of the irradiation unit 46, and seven projections 49 are formed on the irradiation surface 48. As described above, when the rear light guide 39 is formed of a plastic molded product including the filler 65 having a light diffusing action, the filler 65 promotes the light scattering action inside the rear light guide 39, and the skin surface It is possible to make the illuminance of the light radiated toward the light uniform and uniform. Therefore, it is possible to make the light emitted from the irradiation surface 48 more uniform and to prevent the light with high illuminance from entering the eyes of the user and causing discomfort.

As shown in FIG. 6, the irradiation surface 48 is recessed inward in a curved shape toward the inner surface of the skin stimulator 3, and a flat surface 48a is formed at the front end of the peripheral edge thereof. The convex portions 49 are formed in a partially spherical shape, and the concave portions 50 are formed between the adjacent convex portions 49. As described above, by providing the convex portion 49, when the stimulating surface 3a of the skin stimulating body 3 is slid slowly along the facial skin to perform a cosmetic treatment, the convex portion 49 comes into contact with the facial skin to provide rubbing stimulation. You can improve the beauty effect by giving. Further, the beauty treatment can be performed in a state where the projection 49 and the recess 50 hold a highly viscous beauty fluid such as an emulsion on the irradiation surface 48, so that the beauty fluid is unnecessarily applied to the skin surface. Can be prevented.

A seal seat 51, which is slightly larger than the window opening 35, is formed in a step-like shape between the base end of the irradiation unit 46 and the front end of the periphery of the light guide unit 45, and an O-ring mounted around the irradiation unit 46 ( A first seal body) 52 is sandwiched between the inner surface of the skin stimulating body 3 and the seal seat 51. By providing the O-ring 52, the gap between the skin stimulator 3 and the light guide 27 can be sealed in a watertight manner. Since the inner surface of the O-ring 52 in this state is received by the peripheral surface of the irradiation portion 46, the O-ring 52 does not move in the radial direction even when it receives a drop impact, and thus is always in a stable state. The sealing effect can be demonstrated with.

The rear light guide 39 is fastened and fixed to the seat wall of the mounting seat 14 together with the front light guide 38 in a state where the connecting cylinder 47 is engaged and connected to the inner surface of the support cylinder 42 of the front light guide 38. ing. The head case 16 in this state and the base portion 40 of the front light guide 38 are fastened with the seat wall of the mounting seat 14 in between, and the O-ring 52 mounted on the rear light guide 39 is the skin stimulator 3 It is sandwiched between the seal seats 51 and elastically deformed. Similarly, the O-ring 36 mounted on the mounting wall 34 is elastically deformed by being sandwiched between the step portion 20 of the head case 16 and the mounting wall 34. That is, by fastening the head case 16 and the front light guide 38 to the mounting seat 14, the two O-rings 36 and 52 can be elastically deformed at the same time, and the corresponding gaps can be sealed in a watertight manner.

As described above, a space is formed between the front surface of the light source holder portion 41 and the rear surface of the light guide portion 45 by connecting the connection tubular portion 47 to the support tubular portion 42. This space functions as a diffusion space 55 for diffusing the light emitted from the light source holder portion 41, and the diffused light is rearward from the rear surface of the irradiation portion 46 and the inner and rear end surfaces of the connecting cylinder portion 47. The light enters the light guide 39 and is guided to the irradiation surface 48. The light emitted from the light source 26 is refracted when passing through the boundary surface of different media, that is, the front end wall of the front light guide 38 adjacent to the diffusion space 55 and the rear end wall of the rear light guide 39, and further, The light is scattered when passing through the diffusion space 55. Therefore, it is possible to promote the scattering of light and make the illuminance near the center of the irradiation surface 48 and the illuminance at the peripheral edge of the irradiation surface 48 uniform. Therefore, the illuminance of the light radiated toward the skin surface is made uniform over the entire irradiation surface 48, and the beauty treatment is effectively performed while uniformly stimulating the skin surface facing the irradiation surface 48. You can Further, it is possible to prevent the high-illumination light from entering the eyes of the user and causing discomfort.

As shown in FIG. 6, the flat surface 48a at the periphery of the irradiation surface 48 and the skin stimulating surface 3a of the skin stimulating body 3 in the state where the light guide body 27 and the skin stimulating body 3 are integrated are flush with each other. It is possible to perform beauty treatment while sliding the skin stimulator 3 smoothly along the skin surface. Further, when the cosmetic treatment is performed with the cosmetic liquid held on the irradiation surface 48, the cosmetic liquid remaining on the irradiation surface 48 can be completely removed to facilitate cleaning. As described above, when the basic shape of the irradiation surface 48 is formed in a curved shape with an inward recess, the convex portion 49 can be omitted. In that case, the flat surface at the periphery of the irradiation surface 48 is the convex portion 49. Function as.

When using a beauty tool, in order to irradiate a part of the light guided by the light guide 27 toward the periphery of the light guide 27, the pre-stage light guide 38 and the head support 15 covering the periphery thereof are provided. A light irradiation means 58 is provided on the cylinder wall. In this embodiment, the diffusion space 55, the inner irradiation windows (irradiation windows) 59 provided at four locations around the midway portion of the support tubular portion 42 of the front light guide 38, and the inner irradiation window 59 are provided. The light irradiation means 58 is composed of four external irradiation windows (irradiation windows) 60 formed on the cylindrical wall of the head support 15. Further, the irradiation light visually recognizing part 21 is provided in a part of the head case 16 so that the light reaching the outside irradiation window 60 can be visually recognized at the irradiation light visually recognizing part 21. In order to accurately visually recognize the light emitted toward the periphery of the light guide body 27, the irradiation light visual recognition unit 21 is in a state of intersecting with the optical path of the irradiation light emitted from the light irradiation means 58 (the external irradiation window 60 and the normal irradiation window 60). It was arranged in the state of ().

As shown in FIG. 7, the inner irradiation window 59 communicates with the diffusion space 55 described above, and a part of the light irradiated to the diffusion space 55 can be irradiated to the outside of the inner irradiation window 59. The light emitted to the outside of the inner irradiation window 59 can be visually recognized from the outer surface of the irradiation light visually recognizing part 21 through the outer irradiation window 60. In this way, when the light irradiation means 58 is constituted by the diffusion space 55 and the irradiation windows 59 and 60 communicating with the same space 55, the diffusion space 55 and the irradiation windows 59 and 60 are secured in the light guide 27 and the head support 15. By doing so, a part of the light guided by the light guide 27 can be irradiated toward the periphery of the light guide 27.

Therefore, the structure of the light irradiating means 58 is simplified as compared with the case where the light irradiating means 58 is constituted by a structure for diverting, reflecting, or guiding light, and the light guide 27 and the light irradiating are realized. The cost of the beauty device provided with the means 58 can be reduced. Further, since it is sufficient to secure the diffusion space 55 and the irradiation windows 59 and 60, there is no room for failure or malfunction in the function of irradiating light toward the periphery of the light guide 27, and there is an advantage that reliability can be improved. is there. Furthermore, by making a part of the light emitted from the light source 26 visible by the irradiation light visual recognition part 21, the appearance of the skin head 2 when using a beauty tool is made to be a fantastic impression, and the design is improved. Can be improved. In addition, since it is possible to confirm which of the three LEDs 26R, 26G, and 26B is emitting light by confirming the color of the visually recognized light, even if the user's hearing is impaired, You can clearly know the driving condition.

A reflective layer 61 is provided on the inner surface of the cylindrical wall of the head support 15 and the rear surface of the front end wall in order to repeatedly reflect the light emitted to the outside of the inner irradiation window 59 and make it easier to see from the outer surface of the head case 16. Has been formed. The reflective layer 61 is formed by a metal vapor deposition method. As described above, when the reflective layer 61 is formed on the inner surface of the cylindrical wall of the head support 15 and the rear surface of the front end wall, the light reaching the reflective layer 61 is reflected to the irradiation window 60 and the diffusion space 55, and the irradiation light visual recognition section is formed. The illuminance of light at 21 can be increased.

When using a beauty tool, the outer surface of the skin stimulating body 3 is covered with a cotton mat M as shown in FIG. 3, and the holding cap 64 is press-fitted onto the cap mounting portion 17 of the head case 16 to fix the cotton mat M. To do. The cotton mat M in this state is impregnated with lotion, the switch button 4 is turned on, and the switch button 5 is operated to select an operation mode, whereby a drive current is supplied to the heater 31 to generate a pulse current. Since the current adjusting circuit that operates operates in a usable state, the user can perform cosmetic treatment in an operation mode such as an ion derivation mode or an ion introduction mode.

(Ion derivation mode) In the ion derivation mode, while the grip electrode 10 is held with one hand, the cotton mat M impregnated with a cosmetic liquid such as a lotion is slowly slid along the face skin so that the face It can remove fine dirt that has entered the skin's wrinkles, folds, pores, etc. At this time, as shown in FIG. 9, the current stimulation by the pulse current of the positive polarity and the thermal stimulation are applied to the skin surface. Further, the red LED 26R and the green LED 26G are turned on to perform the cosmetic treatment while irradiating the yellow light onto the skin surface. By irradiating the skin surface with yellow light, the skin surface can be activated and the cosmetic effect can be enhanced. The user can confirm that the beauty device is operating in the ion derivation mode by illuminating the skin surface with yellow light.

When the stimulation due to the pulse current acting on the skin surface is weak, the amount of current can be increased and the stimulation on the skin surface can be strengthened by operating the switch button for switching the current intensity. When a fixed time (about 3 minutes) has passed since the pulse current was supplied to the skin stimulating body 3, the supply of the pulse current is stopped, the driving of the heater is stopped at the same time, and the light source 26 and the LED 9 are turned off. As described above, in the ion derivation process, the cosmetic treatment is performed with the skin stimulator 3 side having a positive polarity and the grip electrode 10 side having a negative polarity. As described above, when the cosmetic treatment is performed, the cotton mat M is attached to the skin stimulating body 3, but the holding cap 64 is attached to the cap attaching portion 17 on the peripheral edge of the projecting end of the head case 16. It is possible to prevent 21 from being covered with the cotton mat M. Therefore, as long as the light source 26 emits light when the cosmetic treatment is performed by using the cotton mat M together, the irradiation light visual confirmation unit 21 can confirm that the beauty device is in operation. Moreover, since the beauty treatment can be performed while heating the skin stimulator 3 with the heater 31, when the ion derivation treatment is performed in the cold season, or when the skin stimulation body 3 is brought into direct contact with the skin surface to perform the beauty treatment. By heating the skin stimulator 3 with the heater 31, the beauty treatment can be comfortably performed without feeling the beauty liquid or the coldness of the skin stimulator 3. Further, since the beauty treatment is performed while heating the skin stimulator 3 and the cotton matte M with the heater 31, the skin surface is heated and relaxed to allow the lotion to penetrate into the skin surface and effectively perform the beauty treatment. It can be carried out.

(Ion Introducing Mode) In the ion introducing mode, as in the ion extracting mode, while the grip electrode 10 is held with one hand, the cotton mat M impregnated with a cosmetic liquid such as lotion is slowly moved along the face skin. By sliding, the cosmetic liquid can be penetrated into the skin surface to enhance the moisturizing effect. At this time, thermal stimulation is applied to the skin surface by the heater 31, as shown in FIG. 9, a negative polarity pulse current is supplied to the skin stimulator 3, and a positive polarity pulse current is supplied to the grip electrode 10. It Further, the red LED 26R is turned on to perform a cosmetic treatment while irradiating the skin surface with red light. By irradiating the skin surface with red light in this manner, the skin surface can be activated and the cosmetic effect can be enhanced. In addition, the user can confirm that the beauty device is operating in the ion derivation mode by irradiating the skin surface with red light. When a fixed time (about 3 minutes) has elapsed since the pulse current was supplied to the skin stimulating body 3, the supply of the pulse current is stopped and the light source 26 and the LED 9 are turned off. In the iontophoresis treatment, without using the cotton mat M, the skin stimulator 3 is gently slid along the skin surface in a state where a cosmetic liquid such as a lotion is applied to the face skin to make the beauty. Processing may be performed. In the iontophoresis mode, the skin stimulator 3 and the cotton mat M are heated while being heated by the heater 31, so that the skin surface can be warmed and relaxed to allow the lotion to permeate the skin surface and moisturize. The effect can be enhanced.

(Third Mode) In the third mode, the skin stimulus 3 is applied to the skin surface without using the cotton matte M, with the face skin covered with a sheet mask, or with the emulsion applied to the irradiation surface 48. Slowly slide along to apply beauty treatment. In the third mode, as shown in FIG. 9, thermal stimulus by the heater 31 is applied, and a pulse current of positive polarity and a pulse current of negative polarity are alternately supplied to the skin stimulating body 3, and further, red With the LED 26R blinking, beauty treatment is performed to condition the skin. In this way, by performing the cosmetic treatment with the red LED 26R blinking, the skin cells can be activated and the cosmetic effect can be enhanced. Further, since the red LED 26R is blinking, it can be confirmed that the beauty tool is operating in the third mode. With the red LED 26R turned on, the green LED 26G may be turned on and off intermittently to generate yellow light, and the cosmetic treatment may be performed. When a fixed time (about 3 minutes) has elapsed since the pulse current was supplied to the skin stimulating body 3, the supply of the pulse current is stopped and the light source 26 and the LED 9 are turned off.

As described above, in the beauty device of Example 1, since the beauty treatment is performed while thermally stimulating the skin surface, supplying an electric current, and further irradiating with light, the skin surface is treated as compared with the conventional beauty device. It can be activated to improve the beauty effect. Specifically, by irradiating the skin surface with light, the skin cells on the skin surface can be activated and the metabolism of the skin cells can be promoted. Regarding the activation of skin cells by irradiating the skin surface with red light or yellow light, the physiological mechanism is unknown, but we developed a beauty device equipped with a light source and actually conducted a skin treatment test. It is based on the knowledge confirmed in the process of performing it, and makes it possible to foresee that beauty treatment using light in combination will be universalized in the future (Japanese Patent Laid-Open No. 2011-41706). In addition to the visible light type light source 26, a near infrared LED can be used as the light source 26 for irradiating the skin surface. In that case, in each of the above operation modes, the near-infrared LED can be turned on to perform the cosmetic treatment, or the cosmetic treatment can be performed in combination with the visible light source 26.

In a state where the head case 16 and the light guide 27 are assembled to the main body case 1, the O-ring 52 is elastically deformed and is brought into close contact with the seal seat 51 and the inner surface of the skin stimulator 3, and the O-ring 36 is elastically deformed. In this state, the step portion 20 and the mounting wall 34 are in close contact with each other. Therefore, even if a cosmetic liquid such as lotion permeates along the window opening 35 of the skin stimulating body 3 and the surrounding wall, the cosmetic liquid is sealed by the O-rings 52 and 36, and the lotion stimulates the skin. It is possible to prevent the infiltration into the body 3 and the inside of the head case 16. Therefore, an accident such as a short circuit of the heater 31 and the spring 32 due to the infiltration of the cosmetic liquid can be eliminated, and safety and reliability of the beauty device can be improved. Further, since the skin stimulator 3 and the mounting wall 34 press the O-rings 52 and 36 while elastically deforming them, the skin stimulator 3 can be prevented from rattling, and the skin stimulator 3 and the head case 16 can be prevented. Even if there are variations in the finished dimensions of the above, the variations can be absorbed by the O-rings 52 and 36.

Second Embodiment FIG. 10 shows a second embodiment in which the structure of the irradiation surface 48 is changed. In this case, the irradiation surface 48 is formed as a flat surface, and the same convex portions 49 and concave portions 50 as those in the first embodiment are provided. In the state where the light guide 27 is assembled to the skin stimulator 3, the peripheral edge of the irradiation surface 48 is located within the thickness range of the window opening 35, and the top of the convex portion 49 is flush with the stimulation surface 3 a of the skin stimulator 3. I tried to become one. As described above, when the irradiation surface 48 is formed as a flat surface, compared to the light guide body 27 of the first embodiment, the recess depth of the recess 50 in the irradiation surface 48 is made constant, and more cosmetic liquid is applied to the irradiation surface 48. Can be held at 48. Further, when the skin stimulator 3 is slid slowly along the skin surface to perform a cosmetic treatment, the irradiation surface 48 is prevented from being unnecessarily strongly pressed against the skin surface, and the skin of the skin stimulator 3 is prevented. The hit can be soft and gentle. Furthermore, by positioning the irradiation surface 48 within the thickness range of the window opening 35, the irradiation surface 48 is positioned close to the skin surface, and the light emitted from the light source 26 is effectively irradiated to the skin surface. be able to. Since the other parts are the same as those in the first embodiment, the same reference numerals are given to the same members, and the description thereof will be omitted. The same applies to the following examples.

Example 3 FIG. 11 shows Example 3 in which the structure of the irradiation surface 48 is changed. There, an endless ring-shaped convex portion 49 is doubly formed on the irradiation surface 48, and an endless groove-shaped concave portion 50 is formed on the ring inner surface of each convex portion 49. Thus, when the recess 50 is formed in the shape of an endless groove, the cosmetic liquid can be held in the recess 50 near the center and the peripheral edge of the irradiation surface 48, and the cosmetic liquid is biased to a part of the irradiation surface 48. It can be prevented from being held in the state.

Example 4 FIG. 12 shows Example 4 in which the structure of the irradiation surface 48 is changed. In this case, the irradiation surface 48 is formed as a flat surface, and hemispherical recesses 50 are formed in the center and six locations around the irradiation surface 48 so that the space between the adjacent recesses 50 functions as a projection 49. In this embodiment, when the irradiation surface 48 is pressed against the skin surface, the peripheral edge of the hemispherical recess 50 makes contact with the skin surface, thereby giving a rubbing stimulation to the facial skin and improving the cosmetic effect. In addition, the beauty treatment is performed only in a part of the recesses 50 while holding the beauty treatment liquid to prevent the beauty treatment liquid from being unnecessarily applied to the skin surface. Can be spread evenly.

Example 5 FIG. 13 shows Example 5 in which the structures of the light guide 27 and the light irradiation means 58 are changed. There, a portion corresponding to the front light guide 38 in Example 1 and a portion corresponding to the rear light guide 39 are integrated to form the light guide 27 with one part. Specifically, the light guide portion 45 having a round shaft shape is provided continuously to the light source holder portion 41, the irradiation portion 46 is provided at the front end thereof, and the diffusion space 55 is omitted. Further, the light irradiation unit 58 is configured by the irradiation recess 68 formed in the peripheral surface of the light guide portion 45 of the light guide 27, and the round shaft-shaped irradiation rib 69 provided on the light entrance surface 70 side of the irradiation recess 68. I did it.

The irradiation concave portion 68 and the irradiation rib 69 are formed at four places on the peripheral surface of the light guide portion 45, and the projection end of the irradiation rib 69 is a flat surface and faces the outside irradiation window 60. The irradiation recess 68 is inclined with respect to the central axis of the light guide portion 45 so as to be inclined downward toward the light source 26, and reflects the light reaching the light incident surface 70 from the light source 26 to the irradiation rib 69 side. it can. Accordingly, the light guided by the light guide portion 45 can be emitted toward the periphery of the light guide body 27. In this way, a part of the direction of the light emitted from the light source 26 to the light guide 27 can be reflected and deflected by the light incident surface 70 and can be emitted to the irradiation 60 directly facing the irradiation light visual recognition unit 21. .. Further, since the light reflected and deflected by the light incident surface 70 is guided by the irradiation rib 69 to the vicinity of the irradiation window 60 and is irradiated, the light is irradiated from the light irradiation means 58 and scattered before reaching the irradiation window 60. It is possible to reduce the amount of light to be emitted so that the irradiation light visual recognition portion 21 can be illuminated more clearly.

(Sixth Embodiment) FIG. 14 shows a sixth embodiment in which the structure of the light irradiation means 58 is changed. There, the light guide 27 is composed of one part as in the case of the fifth embodiment, and the irradiation recesses 68 formed at four places on the peripheral surface of the light guide part 45 facing the external irradiation window 60 and the external irradiation window. The light irradiation means 58 is designated by 60. According to the light irradiation means 58, the light emitted from the light source to the light guide body 27 and incident on the irradiation recess 68 can be reflected by the light reflection surface 71 and emitted toward the periphery of the light guide body 27. it can. Specifically, the light incident on the irradiation concave portion 68 can be reflected by the light reflection surface 71 and applied to the irradiation window 60 directly facing the irradiation light visual recognition portion 21, so that the light is applied to the irradiation window 60 by using the scattering effect. Compared with the case of reaching, the irradiation light visually recognizing part 21 can be illuminated with clearer light to accurately notify that the beauty tool is in use.

Example 7 FIG. 15 shows Example 7 in which the structures of the light guide 27 and the light irradiation means 58 are changed. There, the front and rear light source holder 41 of the front light guide 38 has a small front-rear thickness, and the light emitting surfaces of the LEDs 26R, 26G, and 26B mounted on the mounting portion 43 of the light source holder 41 are exposed to the diffusion space 55. .. Further, a portion corresponding to the support tubular portion 42 is formed by four tubular frames 42a continuous with the light source holder portion 41, and a diffusion plate 73 formed of a translucent material is arranged in front of and behind the tubular frame 42a. The light emitted from the light source 26 is diffused every time it passes through the front and rear diffusion plates 73, and is emitted to the periphery of the light guide body 27 from the inner irradiation window 59 between the cylindrical frames 42a adjacent in the circumferential direction. The front-rear length of the connecting tube portion 47 of the rear light guide 39 is shorter than that of the connecting tube portion 47 of the first embodiment.

In this case, the light guide 27 is composed of one part, the light source holder 41 is recessed at the rear end thereof, and the light guide 45 is provided on the front side of the light source holder 41. A flange portion 74 is projected around the light source holder portion 41, and the flange portion 74 is fastened and fixed to the front end wall of the head support body 15 with a screw 75. Further, a metal shading plate 76 is fixed to the center of the front surface of the irradiation unit 46, and a ring-shaped irradiation surface 48 is provided around the shading plate 76. The irradiation surface 48 was formed as a concave back curved surface so that the cosmetic solution could be held.

The light source 26 is composed of an LED board 77 and three full-color LEDs 26C mounted on the board 77. The LED board 77 is arranged around the light source holder section 41 in a state where the full-color LED 26C faces the rear surface of the light guide section 45. Fixed on the wall. In this embodiment, the light emitted from the light source 26 cannot be emitted to the periphery of the light guide body 27, but an LED dedicated to visual recognition which emits light in synchronization with the light emitting operation of the light source 26 is provided inside the outer irradiation window 60. By arranging them, it is possible to visually recognize the light emitting state of the LED dedicated to visual recognition according to the usage status of the beauty tool.

The camera 81 photographs the state of the skin surface while irradiating light from the light source 26 when using a beauty device, and thus the skin surface abnormality represented by pigment spots such as stains and dullness and pigmentation such as freckles. Can be captured as an image. The image captured by the camera 81 is sent to a determination unit (skin abnormality detection unit) 88 provided on the control board 7, and the presence or absence of pigment spots or pigment deposition is determined in real time. When an abnormality on the skin surface such as pigmented spots or pigmentation is confirmed, a speaker (notifying body) 89 is activated to emit a warning sound to notify the user that there is an abnormality on the skin surface. The user who hears the warning sound identifies the content and position of the abnormality on the skin surface, takes measures to make spots, dullness, freckles, etc. inconspicuous, or applies a cosmetic solution containing medicinal ingredients. Do skin care.

As described above, according to the beauty tool of the tenth embodiment, it is possible to notify the user at an early stage that there are spots, dullness, freckles, etc. on the skin surface concurrently with performing the beauty treatment. In addition, at the same time as detecting the skin abnormality, the skin stimulator 3 introduces ions into the skin abnormal portion such as a spot or dullness, so that the skin abnormal portion can be accurately covered.

Although the speaker 89 is used as the notification body in the tenth embodiment, the notification body 89 can be configured by a light-emitting body or a vibration generator other than sound. If necessary, the notification body 89 can be configured by combining a plurality of notification elements of sound, light, and vibration. The light source 26 may also serve as the notification body 89. In that case, blinking the irradiation light visual recognition unit 21 or changing the color of the light emitted from the light source 26 causes skin abnormality on the skin surface. Can be clearly notified. Further, at the same time as detecting the skin abnormality, the current for ion introduction is automatically increased, the cosmetic effect associated with ion introduction is improved, and the skin abnormality can be effectively eliminated. In that case, since the output current to the skin stimulator 3 can be automatically increased at the same time when the skin abnormality is detected, the user can save the trouble of performing the switch operation. In addition, when the normal skin care current is set to 1, the current after the enhancement due to the skin abnormality may be about 1.2. Further, when the current supplied to the skin stimulator 3 is 0 or 0.5 when performing the cosmetic treatment while irradiating the light from the light source 26, the current after the enhancement due to the skin abnormality is 1. It may be. The light source 26 may be configured to irradiate treatment light, and in the state where the skin abnormality detection unit 88 detects an abnormality on the skin surface, the light emission intensity of the light source 26 that irradiates treatment light is enhanced, The treatment effect can be enhanced.

As described above, when the skin abnormality detecting unit 88 detects the abnormality on the skin surface, if the emission intensity of the light source 26 is increased, the intensity of the light for treatment is increased at the same time as the detection of the skin abnormality, so the treatment effect is improved. Thus, skin abnormalities can be effectively reduced. Further, since the light emission intensity of the light source 26 in the case of performing the beauty treatment may be such that the skin abnormality can be captured as an image by the camera 81, the healthy light does not damage the healthy skin surface.

The beauty tool of Example 10 can be implemented in the following forms.
A beauty device comprising a skin electrode 3 capable of supplying an electric current to the skin surface,
A skin abnormality detecting unit 88 for detecting an abnormality on the skin surface,
A beauty instrument characterized by comprising an alarming body 89 for generating at least one of sound, light, and vibration when the skin abnormality detecting section 88 detects an abnormality on the skin surface.
According to the beauty device having the above-described configuration, the skin abnormality detection unit confirms that spots, dullness, freckles, etc. are formed on the skin surface in parallel with supplying electric current from the skin electrode 3 to the skin surface for beauty treatment. It is possible to detect at 88 and notify the user at the same time with the detection by the notification body 89. The user who hears the warning sound identifies the content and position of the abnormality on the skin surface, takes measures to make spots, dullness, freckles, etc. inconspicuous, or applies a cosmetic solution containing medicinal ingredients. Can provide skin care. In addition, when the skin abnormality is detected and at the same time, the skin stimulator 3 introduces ions into the skin abnormality portion such as a stain or dullness, the countermeasure for covering the skin abnormality portion can be appropriately performed.

The above-mentioned beauty device which increases the output current of the skin electrode 3 in a state where the skin abnormality detection unit 88 detects an abnormality on the skin surface.
According to this beauty device, when the skin abnormality is detected and the current for ion introduction is automatically increased, the beauty effect associated with ion introduction can be improved and the skin abnormality can be gradually improved. Further, since the output current to the skin stimulating body 3 can be automatically increased at the same time when the skin abnormality is detected, it is possible to save the user the trouble of performing the switch operation.

The light guide 27 can be formed of a conductive resin. In that case, the skin is stimulated by supplying an electric current to the skin stimulator 3 which supplies an electric current to the skin surface and the light guide 27 to perform skin treatment. Compared to the case where the stimulator 3 alone supplies the electric current to the skin surface, the electric current can be supplied to the skin surface in a wider area, and the beauty treatment can be effectively performed.

In Example 1, the skin surface was irradiated with red or yellow light, but this is not necessary, and all the LEDs 26R, 26G, and 26B are turned on to irradiate the skin surface with white light (visible light) for beauty treatment. You may go. In addition, only the green LRD 26G or only the blue LED 26B can be turned on to perform the cosmetic treatment. In short, if the color of the light is such that the cosmetic treatment can be effectively performed, the color of the light radiated on the skin surface is It can be any color. The light source 26 that irradiates the skin surface may be a light source that irradiates ultraviolet light of a specific wavelength for skin treatment, in addition to a visible light type or near-infrared light type light source.
