BEST MODE FOR CARRYING OUT THE INVENTION A preferred embodiment of the facial equipment of the present invention will be described below with reference to the drawings.
The facial beauty device of the present invention has a function of detecting pore stains such as blackheads and keratotic plugs on the skin by irradiating the user's skin with light of a specific wavelength from the light emitting unit. It is a facial device that can clean only the areas where the pore dirt is present, that is, only the necessary areas.

<One embodiment of facial equipment>
In a preferred embodiment of the present invention, as shown in FIG. 1, the facial beauty device 1 includes a facial beauty device main body 10, a plate-like head portion 20, a cap 30 on the facial beauty device main body 10, a light emitting portion 40, and a charger. 50 (see FIG. 5). The head part 20 extends from one end of the facial beauty device main body 10 toward the outer side in the longitudinal direction of the facial beauty device main body, and cleans pores present on the skin. It also has the function of removing dirt from the skin, so it is sometimes called a “peeler”. The light emitting unit 40 is located at one end of the facial equipment main body 10 and on one side of the head unit 20, and emits light having a first specific wavelength toward the skin to remove dark spots and dark spots on the skin. Develops a function to detect pore dirt such as keratin plugs.

The facial equipment main body 10 is configured, for example, in a rod shape that is easy for the user to grip, and has a portion that is held by hand. An operation unit 11 for operating various functions of the facial beauty device 1 and a display unit 12 for displaying the usage status of the various functions are arranged on the surface of the facial beauty device main body 10 .

The cap 30 is separably (detachably) attached to one end of the facial equipment main body 10 . The charger 50 is connected to the other end of the facial equipment body 10 . In addition, in the present embodiment shown in FIG. 1, the facial device 1 has an ultrasonic vibration (SONIC) function of generating ultrasonic vibration, in addition to the light irradiation function of irradiating the user's skin with light of a predetermined wavelength It has an ion function to electrify the head part and perform ion introduction (or ion extraction) to the user's skin, which will be described later, and an EMS function to electrically stimulate the muscles under the user's skin and, in some cases, the tendons. , the facial equipment of the present invention is not limited to these embodiments.

[Light irradiation function]
As a light irradiation function, a function of detecting pore stains on the skin, such as blackheads, keratotic plugs, etc., by irradiating light of a first specific wavelength from the light emitting unit 40, and a wavelength other than the first specific wavelength (second specific wavelength ) to perform cosmetic treatments such as blood circulation promotion. Incidentally, the light emitting unit 40 will be described in detail later.

As the light with the first specific wavelength, it is preferable to use visible light with a blue wavelength around 405 nm. If the wavelength of the light is longer than the specific wavelength, the color difference between the skin and pore stains is less likely to occur, making it difficult to detect stains. More specifically, the first specific wavelength light is light with a blue wavelength in the range of 360 nm to 420 nm, for example, preferably in the range of 380 nm to 420 nm, more preferably in the range of 400 nm to 410 nm, Most preferred is 405 nm light.

As the wavelength becomes shorter than the light of the first specific wavelength, the stain detection function improves, but since the human visual sensitivity decreases in the short wavelength region, it becomes difficult to maintain the illuminance. In addition, if the wavelength is shorter than the light of the first specific wavelength, it approaches the ultraviolet range, which may put a burden on the skin.

As the light with the second specific wavelength, for example, light with a red wavelength of 620 nm to 660 nm can be used. Light with a wavelength of about 620 to 660 nm has the function of activating skin cells, and is therefore useful for skin care, such as preventing skin diseases and moisturizing the skin. It should be noted that medicinal ingredients such as beauty essences often have a negative charge, so by charging the head section 20 negatively when irradiating with red light, as will be described later, the repulsion of the negative charges will cause penetration into the skin. can be promoted. However, regardless of whether or not the head section 20 is charged, it is possible to further improve the health condition of the skin by irradiating the light of the second specific wavelength as described above.

[Ultrasonic transducer]
It is preferable that the facial device 1 further includes an ultrasonic vibration element that applies ultrasonic vibrations to the head section 20 . When the head section 20 is ultrasonically vibrated by the ultrasonic vibration element, dirt on the skin can be lifted up and easily removed. In addition, an improvement in the skin care effect due to the massage action can be expected. Here, it is preferable to wet the skin with water, lotion, gel, or the like when performing ultrasonic vibration. The burden on the skin can be reduced by not directly applying ultrasonic vibrations to the skin but by transmitting the ultrasonic vibrations through moisture. In addition, cleaning called water peeling, in which floating dirt is blown away by vibration of water, is also possible. Furthermore, it can promote penetration of medicinal ingredients such as gels and beauty essences and water into the skin. Thus, according to the ultrasonic vibration function derived from the ultrasonic vibration element, applying ultrasonic vibrations to the user's skin can provide cosmetic treatment effects and skin cleaning effects.

Here, the ultrasonic transducer is also called an ultrasonic transducer or an ultrasonic oscillator, and for example, electrostrictive and magnetostrictive types are known. In the present invention, the type of ultrasonic transducer is not particularly limited, and any type can be used. There is no particular limitation on the resonance frequency, and for example, commercially available ultrasonic transducers such as PZT transducers and BL transducers having a frequency of about 15 to 200 kHz, particularly about 20 to 50 kHz may be used. These elements can be installed, for example, in the root portion of the head portion 20 (for example, inside the facial equipment main body 10).

[Iontophoresis device]
It is preferable that the facial equipment 1 further includes an iontophoresis device that causes at least one of positive charging and negative charging to the head portion. In general, dirt on the skin is often negatively charged. By positively charging the head portion 20, the negatively charged dirt is attracted to the head portion 20 and rises from the skin. facilitates removal and cleaning by In addition, since many medicinal ingredients such as beauty essences are negatively charged, by charging the head section 20 negatively, the repulsion of the negative charges can promote penetration into the skin.

By positively or negatively charging the head portion 20 in this manner, ions of medicinal ingredients and ions of dirt can be introduced into or extracted from the user's skin, thereby achieving skin cleaning effects and cosmetic effects. Therefore, in the present invention, unless otherwise specified, all charging devices are broadly referred to as iontophoresis devices. In general, the operation of positively charging the head portion 20 has the function of expelling ions of dirt components from the skin, so the operation of negatively charging the head portion 20 has the function of promoting the permeation of medicinal component ions. It is sometimes distinguished from (narrowly defined) iontophoresis as a different name.

The iontophoresis device may be any device as long as it has a function of positively or negatively charging the head section 20 . For example, the head section 20 can be positively or negatively charged by passing a pulse type direct current (intermittent direct current) through the tip of the head section 20 . Here, as will be described later, if the entire head portion 20 is made of a conductor such as metal, ions can be introduced by applying a voltage to the end of the head portion 20 on the side of the facial beauty device main body 10 . If the head portion 20 is a non-conductor such as resin, a conductor such as a thin metal plate is extended or moved along the surface of the head portion 20 to its tip, and a voltage is applied to the end on the side of the facial equipment body 10 . should be applied. The voltage at this time can be generated, for example, from a substrate inside the facial equipment main body 10 . The voltage here is preferably, for example, about 1 to 5 V, particularly about 3.5 to 4.0 V, from the viewpoint of both ion introduction effect and safety.

The iontophoretic device may charge the head portion 20 either positively or negatively, but is preferably capable of charging both positively and negatively. In particular, if it is a mechanism that can switch the charged state of the head portion between positive and negative by operating the operation portion 11 on the surface of the main body 10, it is possible to switch between the stain removal cleaning mode and the skin care mode using medicinal ingredients or the like by hand operation. possible and preferable. In the skin care mode, it is preferable to apply lotion, gel, or cream containing medicinal ingredients to the surface of the skin.

Since ion derivation can contribute to cleaning the skin, it is effective to irradiate the skin with light of the first specific wavelength. In this case, it is preferable to moisten the skin with water, lotion or gel. On the other hand, iontophoresis in a narrow sense promotes the penetration of medicinal ingredients into the skin and can contribute to skin care. effective to do so. In one embodiment of the present invention, there is a mode in which the light of the first specific wavelength is emitted from the light emitting unit 40 while the head unit 20 is positively charged, and a mode in which the light of the first specific wavelength is emitted from the light emitting unit 40 while the head unit 20 is negatively charged. It is preferable that there is a mechanism for switching between modes for irradiating light of two specific wavelengths. However, it is of course possible to negatively charge the head portion 20 to facilitate the removal of positively charged dirt, or positively charge the head portion 20 to facilitate penetration of medicinal ingredients having positive ions into the skin. .

[EMS device]
The facial equipment 1 preferably further includes an electrical stimulation (EMS) device that provides electrical stimulation to muscles under the skin through the head section 20 . EMS is an abbreviation for Electrical Muscle Stimulation, and is an operation of applying electrical stimulation to muscles or tendons and the skin of the upper layers thereof. According to the EMS function, a cosmetic effect is produced by applying electric stimulation to the user's skin or the like. For example, by applying an electric current to the zygomatic muscle and stimulating it, it is possible to improve or prevent a drooping corner of the mouth, a double chin, a sluggish face line, and the like. It is also possible to improve blood flow at the site to which electrical stimulation is applied.

There is no particular limitation on the method of electrical stimulation by EMS. For example, an alternating current with a frequency of 1 to 100 Hz, particularly 10 to 50 Hz may be applied to loosen the skin and muscles, or an intermediate frequency current of about 1 kHz may be applied to loosen the muscles. The electric current at that time is preferably about 100 to 1000 μA, particularly about 200 to 700 μA, from the viewpoint of both electrical stimulation effect and safety. In the facial equipment of the present invention, for example, a low EMS mode with a frequency of 0.1 to 1000 Hz, especially about 10 to 100 Hz, and a high EMS mode with a frequency of 1000 Hz or more, especially about 2000 to 10000 Hz. It is also possible to adopt a system that combines both and switches between them. It should be noted that, even when applying electrical stimulation by EMS, it is preferable to apply a gel or cream to the surface of the skin, as described later, in order to prevent troubles from occurring on the skin.

[Head part]
The head part 20 has the function of cleaning the pore dirt present on the skin as described above, and is arranged at one end of the facial equipment main body 10 as a peeler, for example. Preferably, the head part 20 is made of a metal material and has a plate-like shape, and extends in the longitudinal direction of the facial equipment main body 10 . Here, "plate-like" does not necessarily mean a flat plate. From the viewpoint of the strength of the head portion 20 and the ease of cleaning the skin, it is preferable that the head portion 20 has a curved plate-like shape. Moreover, from the viewpoint of safety to the skin, it is preferable that one end of the head section 20 on the human body side is rounded. As shown in FIG. 3, it may have a structure in which the central portion is recessed. The head unit 20 transmits ultrasonic vibrations and electrical stimulation to the user's skin. Here, it is preferable that the head portion 20 is made of a conductive material, such as a metal material, because it facilitates ion introduction or voltage application in EMS. In particular, it is preferably made of stainless steel because it is easy to clean, does not easily rust, and is relatively resistant to metal allergies.

[cap]
It is preferable that the facial device 1 further has a separably attached cap 30 at one end. The cap 30 is detachably attached to one end of the facial equipment body 10 . The cap 30 is attached to one end of the facial beauty device body 10 when the facial beauty device 1 is not in use, and protects the head portion 20 and a light emitting portion 40 which will be described later. The outer layers of the cap 30 and the beauty device main body 10 are molded from organic polymers such as thermoplastic resins such as polyolefin, polystyrene, polyester and polyamide, and thermoplastic elastomers such as TPS, TPO, TPU, TPAE and TPEE. It is preferable from the viewpoint of water resistance, light weight, cost, and the like. Also, the grip portion and the like on the surface of the facial equipment main body 10 may be made of thermoplastic elastomer, rubber, or the like.

[Light-emitting part]
It is preferable that the light emitting unit 40 is configured by a light emitting diode (LED) 41 . In this embodiment, the light-emitting part 40 is arranged at one end of the facial equipment main body 10 where the head part 20 is arranged and on one side of the head part 20 .

The light emitting unit 40 is preferably composed of a first light emitting diode that emits light of a blue wavelength in the wavelength range of 360 to 420 nm, particularly around 405 nm, as the light of the first specific wavelength. Further, the light emitting section 40 may have a second light emitting diode having a second specific wavelength that emits red light as light other than the specific wavelength. The second specific wavelength is preferably light in the wavelength range of 620-660 nm. The light-emitting portion 40 also preferably includes both a first light-emitting diode and a second light-emitting diode.

Regarding the light-emitting part 40, if the illuminance is low, dirt cannot be sufficiently visualized, so it is preferable to use an LED chip that can irradiate with sufficient illuminance. In addition, since it is possible to increase the illuminance and concentrate the irradiation range by providing a lens function, it is preferable that the LED chip to be used is not a flat type but a cannonball type (see FIG. 3).

Light-emitting diodes (first light-emitting diodes and/or second light-emitting diodes, also referred to as LED chips) 41 in the light-emitting portion 40 have insufficient illuminance if they are too small, and if there are too many, the illuminance is too high to cause glare during use. It is preferable to arrange 6, particularly 2 or 3. Although three LED chips 41 are arranged in one row in FIG. 3, the arrangement of the LED chips 41 in the facial equipment of the present invention is not limited to such an embodiment. For example, three first light-emitting diodes and three second light-emitting diodes may be arranged in parallel in rows, or two first light-emitting diodes and two second light-emitting diodes may be arranged in parallel. They may be arranged in one row.

Also, when a plurality of LED chips 41 are arranged, if the irradiation range on the skin is too wide, the illuminance cannot be ensured. In addition, the place where the LED chip is arranged may be subjected to a coating treatment such as aluminum vapor deposition in order to give it a reflector function and increase the illuminance.

In addition, since the facial equipment 1 is generally used on wet skin, it is desirable that the facial equipment 1 has a waterproof function, and it is preferable to install a waterproof protective cover on the portion where the LED chip is arranged. Here, by making the waterproof protective cover as transparent as possible, it is possible to irradiate the skin while maintaining high illuminance. Also, the waterproof protective cover may have a convex shape and have a lens function to increase the illuminance of light.

[Charger]
It is preferable that the facial device 1 further includes a charger 50 . From the viewpoint of avoiding the concentration of equipment around the head portion 20, the charger 50 is attached to an end portion (the other end portion) different from the end portion to which the cap 30 is attached, for example, the side opposite to the cap 30 of the facial equipment main body 10. It is preferably connected to the ends. For example, as shown in FIGS. 4 and 5, the charger 50 includes a charging base 51 to which the other end of the facial equipment 1 is connected, a charging cable 52 whose one end is connected to the charging base 51, and a charging cable 52. and a connection terminal 53 arranged at the other end and connected to the power supply P. Charger 50 is used to charge facial device 1 .

<How to use the facial device>
As shown in FIG. 6, the facial beauty device 1 described above is used with the tip of the plate-like head portion 20 in contact with the user's skin. In this case, it is used such that the light emitting section 40 is arranged above the head section 20 . Thereby, the predetermined range of the user's skin can be irradiated by the light emitting unit 40 . From the viewpoint of operability during use, as shown in FIGS. 2 and 6, the head portion 20 is bent in the vicinity of its base in the opposite direction to the light emitting portion 40, and halfway along the extending direction of the facial beauty device main body 10. It is preferable to have a structure that is parallel or bent again in the direction of the light emitting section 40 side. With such a structure, it is possible to irradiate a relatively wide area of the skin around the portion in contact with the head.

Here, pore stains on the skin, such as blackheads and keratotic plugs, can be detected by irradiating visible light with a blue wavelength around 405 nm from the light emitting unit 40 . As a result, the head portion 20 can peel only the areas of the user's skin where pore stains such as blackheads and keratin plugs are present. Therefore, according to the facial equipment of the present invention, it is possible to clean only the required area and remove dirt on the skin without putting a burden on the skin.

The facial equipment 1 of the present invention, particularly the facial equipment equipped with an ultrasonic vibration element, an iontophoretic device, and/or an EMS device, can be cleaned by stroking the skin surface with the facial equipment 1 without applying almost any pressure to the skin. can do. From such a point of view as well, according to the facial equipment of the present invention, it is possible to reduce the burden on the skin during cleaning.

From the viewpoint of reducing the burden on the skin, it is preferable to apply water, lotion, gel, or cream to the surface of the skin when using the facial device 1 of the present invention. Since the head of a facial device is usually used by sliding it over the surface of the skin, irritation from friction may cause skin problems. The burden on the skin in such a case can be reduced by the facial equipment of the present invention, but it can be further reduced by applying gel or the like. Therefore, it is desirable to use a protective agent such as lotion, gel, or cream, or water when cleaning, ion-implanting, or applying electric stimulation to the skin by ultrasonic vibration or EMS. In addition, if gel or cream is applied in the skin care mode, the medicinal ingredients contained in them will permeate the skin, making it possible to achieve a more effective cosmetic treatment function.

A preferred embodiment of the facial device 1 of the present invention has been described above, but the present invention is not limited to the above-described embodiment and can be modified as appropriate.
