Description Ultrasonic beauty method and device

The present invention relates to a cosmetic method and apparatus using ultrasonic waves. Background art

Conventionally, a device for activating skin using ultrasonic waves has been known. For example, an ultrasonic vibration actuator Yue proposed by the present inventor and disclosed as Japanese Patent Application Laid-Open No. Hei 6-328042 is a diaphragm, a keel plate attached to both sides of the diaphragm, and a keel plate. This device has a deformed bimorph structure consisting of a piezoelectric ceramic vibrator attached to the surface, and is applicable to the activation of skin.

In this ultrasonic vibration factory, a voltage was applied to each piezoelectric ceramic so that the relationship between the direction of polarization and the direction of the electric field was opposite to each other. A large displacement can be taken out.

However, when using the above-mentioned ultrasonic vibration actuator and applying a DC voltage between the diaphragm and the skin, the current is applied only to the surface between the brass side and the minus side. Does not flow and current spread is small. In other words, the current flowing through the skin is limited to a very narrow range, which is not always enough to activate skin hemp. Disclosure of the invention

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problem, and aims to further activate the skin by flowing current more effectively over the skin in addition to the mechanical vibration caused by the diaphragm. It is an object of the present invention to provide an ultrasonic cosmetic method and apparatus that can be used.

The method according to the present invention includes the steps of: bringing a metal diaphragm vibrated by ultrasonic waves into contact with the skin; While applying a voltage containing an AC component between the diaphragm and the skin / S ", the handshake is moved along the surface of the skin. The applied voltage is preferably an AC voltage and a DC voltage. The AC voltage is synchronized with the vibration of the diaphragm.The apparatus according to the present invention is an ultrasonic vibrating machine equipped with a metal vibrating plate vibrating by ultrasonic waves. And a power supply for outputting a voltage including an AC component for application between the diaphragm and the skin / f. Preferably, the power supply is for supplying to the ultrasonic vibrator. A transformer for obtaining an AC voltage from the AC power supply by electromagnetic induction and a rectifier for rectifying the AC voltage output from the transformer are provided. Keel plates attached to both sides of the And an ultrasonic vibrator attached to each keel plate, wherein a curved surface having a diameter substantially equal to a quarter of the vibration wavelength of the vibrating plate is formed at the tip of the vibrating plate.

By bringing the working part of the diaphragm into contact with the subject's ^ ?, a pulsating voltage synchronized with the ultrasonic vibration is applied to the skin. By applying a pulsating voltage to the skin, electricity is applied from the surface of the skin through various barriers of the lower tissue and intercellular binding water, and an ionizing action of the water is generated by energizing the subcutaneous tissue.

The pulsating voltage is obtained, for example, by electromagnetic induction from a vibration voltage applied to the ultrasonic transducer. In this case, the pulsating voltage and the oscillating voltage are completely synchronized, and a current flows over a wide area of the skin, which is effective in activating the skin.

Therefore, according to the present invention, in addition to the mechanical vibration caused by the diaphragm, the current can be more effectively applied to the skin, thereby further activating the skin. In addition, the synergistic effect of the vibration and the application of a pulsed voltage can further activate the skin.

In FIGS. 1 and 2, the vibration mechanism 7 corresponding to the ultrasonic vibration factor of the present invention includes a vibration plate 11, a keel plate 12a, 12b, and an ultrasonic transducer 13a1. , 13a2, 13b1 and 13b2, and insulation layers 14a and 14b. All or part of the ultrasonic vibrator 1 3 al, 1 3 a 2, 1 3 b 1, 1 3 b 2 is replaced with the ultrasonic vibrator 1 3 or the ultrasonic vibrator 1 3 a Oscillator 1 3b ”may be written.

The vibration plate 11 is made of a metal such as a stainless steel plate or a hard thin copper plate, and has elasticity that flexibly flexibly.

The keel plates 12a and 12b are used to convert the shear wave displacement into longitudinal waves, and are made of stainless steel plate (or aluminum, duralumin), etc., having a thickness similar to that of the diaphragm 11 . These keel plates 12 a and 12 b are firmly attached to the surfaces on both sides of diaphragm 11 by a structural adhesive so as to be elastically coupled to diaphragm 11.

What are the ultrasonic transducers 13a and 13b, for example? It consists of a ZT-based disc-shaped piezoelectric ceramic plate. The ultrasonic transducers 13a and 13b are arranged on the surface of each of the insulating plates 1a and 1b so that the respective polarization directions are the same, and are provided by a structural adhesive or the like. Are glued together. In this embodiment, the ultrasonic transducers 13 al, 13 a 2 and 13 bl, 13 b 2 of 2Ϊ) are provided on the respective surfaces, and are connected in parallel. The number of the ultrasonic transducers 13a 'and 13b may be increased according to the required power.

The insulating plates 14a and 14b are thin plates made of a hard epoxy resin, and the ultrasonic transducers 13a and 13b have a 30-micron-thick copper foil with good conductivity on the surface where they are strongly attached. Are laminated. The insulating plates 14a and 14b electrically insulate the ultrasonic oscillators 13a and 13b from the keel plates 12a and 12b and the vibrating plate 11, and also provide an ultrasonic oscillator 13 b. Elastic connection between 13 b and keel plates 12 a and 12 b is almost complete.

Each part of the vibration mechanism 7 is adhered to each other, for example, as follows, and is firmly adhered.

For bonding the diaphragm 11 to the keel plates 12a and 12b, use a thermosetting epoxy resin containing dithiazamide as a structural adhesive and pressurize for pressure welding to 135 ° Perform processing for 1 hour at C.

To bond the keel plates 12a, 12b and the insulating plates 14a, 14b, use polyamide amide and alumina-containing scotch weld (made by 3M) and cure at 100-125 for 1 hour. .

The bonding between the ultrasonic transducers 13a, 13b and the insulating layers 14a, 1b requires strong bonding with emphasis on conductivity, unlike mechanical structure bonding. Further, carbon is added to the mixture, and the mixture is cured by sintering at 135 ° C for 1 hour. Furthermore, the temperature is naturally lowered from 135 ° C, and annealing (annealing) is performed so that no shrinkage distortion occurs due to a sudden change in the temperature of the bonding surface.

Therefore, by applying a vibration voltage of, for example, 20 to 60 kHz to the ultrasonic transducers 13 a and 13 b, a longitudinal wave is propagated to the working portion EF at the tip of the diaphragm 11 and Vibration displacement occurs. By changing the length or thickness of the keel plates 12a and 12b from each other, a modified bimorph structure can be obtained. As such a structure, it is possible to adopt various structures described in JP-A-6-328042. As shown in FIG. 3, the distal end portion of the diaphragm 11 is bent downward in the figure to form a curved surface, and is bent upward in the figure to form a curved surface. 1 and 2.

The radius of curvature R 1 of the portion 1 12 is half of the vibration wavelength λ of the diaphragm 11, that is, 1/8 wavelength. The radius of curvature R2 of the portion 1 1 1 is about 1/4 of the radius of curvature R1. For example, when the vibration wavelength 1 is 9 millimeters, the radius of curvature R1 is 4.5 millimeters, and the radius of curvature R2 is 1 to 1.5 millimeters. The action portion EF at the tip of the diaphragm 11 has an inclination of about 20 degrees upward.

Make dimension L4 as small as possible and make dimension L3 as long as possible. Dimensions L1 and L2 should be as equal as possible to ensure good vibration balance. Dimensions L5 and L6 are also made as equal as possible to achieve good vibration balance.

As described above, the distal end of the diaphragm 11 is not a mere open end, but is formed into a curved surface with the radii of curvature R 1 and R 2. The inner diameter side of the curved surface is easily expanded and the outer diameter side is easily contracted, and has a kind of spring effect, so it has a buffering effect and is advantageous in generating longitudinal vibration.

As shown in FIG. 4, the contact portion of the leading edge of diaphragm 11 with the skin is formed in an arc shape having a radius of curvature R3. The width L7 of the arc-shaped portion is equal to the radius of curvature R3. As a result, the leading edge of the diaphragm 11 is easily adapted to rot. Since the leading edge is arc-shaped, its length is longer than that of a straight line. When the tip 緣 is pressed against ^ and moved, there is an effect that the swelling due to the expansion and contraction of the skin is less likely to be caught.

As shown in FIGS. 5 and 6, the vibration mechanism 7 is made of a synthetic resin or metal casing. It is housed in the thing 21 and is held by dampers 22, 23, 24 made of synthetic rubber.

The damper 24 fixes the rear end of the diaphragm 11. The dampers 23 press the middle part of the diaphragm 11 on both sides. The damper 22 presses and fixes the diaphragm 11 from the upper and lower surfaces at the outlet of the casing 21. Since the dampers 122 also exert a sealing function, this provides a simple waterproof structure. The diaphragm 11 vibrates like a repellent, for example, with a portion supported by the damper 22 as a fulcrum.

Electrical connection to the vibration mechanism 7 is made by a cable 31 inserted through a bushing 25 attached to the rear end of the casing 21. The cable 31 has four core wires. One pole (CP 2) of the ultrasonic vibrator 13, the other pole (CP 1) of the ultrasonic vibrator 13, and the ground (CP 4), and diaphragm 11 (CP 3).

In FIG. 7, the control device 4 includes a power supply noise countermeasure circuit 201, a power supply circuit 202, an oscillation circuit 203, a drive circuit 204, an evening variable circuit 205, and a regulator 206. , Intermittent signal generation circuit 207, control panel 209, changeover switch 209, transformer 210, transformer 221, rectifier 221, capacitor 213, variable resistor 211, and switching It consists of switches 2 15.

The power supply circuit 202 supplies a positive DC voltage Vcc and a negative DC voltage Vss to the drive circuit 204 and also supplies a DC voltage to each part.

The oscillation signal output from the oscillation circuit 203 is input to the drive circuit 204 via the switch 209. In the ISSj circuit 204, power amplification is performed by a transistor or the like, and output to the primary side of the transformer 210.

The output of the oscillation circuit 203 is also input to the intermittent signal generation circuit 207, and when the switch 209 is switched, the intermittent signal generation circuit 207 intermittently drives the drive circuit 207. Output to 4. The intermittent signal generation circuit 207 is, for example, 10 to 2 Output intermittently at a cycle of 50 msec. Timing variable circuit 2 (# 5 generates an intermittent signal. Adjuster 206 adjusts the timing of generating the intermittent signal.

The control panel 208 is provided with a display lamp for indicating an operation state of each unit, a display for displaying voltage or current, a display circuit for indicating a mode or a switching state, and the like.

The oscillating voltage induced on the secondary side of the transformer 210 is output to the terminals CP 1, 2, and is applied to the ultrasonic transducer 13 via the cable 31 therefrom. Part of the oscillating voltage is extracted via the transformer 211. The transformer 211 is a one-turn coil whose primary side is a toroidal core with an electric wire penetrated, and generates a voltage on the secondary side wound several times by electromagnetic induction. The output on the secondary side of the transformer 211 is full-wave rectified by the rectifier 211, and the waveform is adjusted by a smoothing circuit composed of the capacitor 211 and the variable resistor 214.

When the resistance value of the variable resistor 2 14 is small, as shown in A of Fig. 8, the AC component VA 1 force <small and the DC component becomes a large pulsating flow, and the resistance value of the variable resistor 2 14 When is large, the AC component VA 2 is large and the DC component is small, as shown in FIG. 8B.

The direction of the polarity of the pulsating flow that has passed through the smoothing circuit is selected by the switching switch 215, and is output between the diaphragm 11 of the vibration mechanism 7 and the wristband WB. The wristband WB is attached to the wrist of the beauty subject, and the working portion EF at the tip of the diaphragm 11 is brought into contact with the surface of the skin such as the subject's face or hand. Will be applied to the skin of the person.

The pulsating voltage VF has a peak value of 6 VH¾ considering the resistance of the human body. However, the voltage applied to the skin via water is kept within 2 V from 0.675 V, which electrolyzes or dissociates the water. As described above, the impulse-like weak pulsating voltage is applied to the subject's skin via water.

Next, the method of use and operation of the ultrasonic cosmetic device 1 will be described.

Connect the main unit 3 and the control device 4 as shown in Fig. 7, and use the wristband WB Wear it on your wrist. The power supply circuit 202 is turned on, and an oscillating voltage is applied to the ultrasonic oscillator 13. As a result, the ultrasonic vibrator 13 vibrates, and the working portion EF of the vibrating plate 11 vibrates. By bringing the working portion EF 'of the diaphragm 11 into contact with the skin of the subject, a pulsating voltage VF synchronized with the ultrasonic vibration is applied to the skin.

When the switching switch 2 15 is switched upward as shown in FIG. 7, the diaphragm 11 has a positive pole and the human body has a negative pole. When the switching switch 2 15 is reversed, the diaphragm 11 becomes a negative pole and the human body becomes a positive pole. In this case, a current flows from the skin surface of the human body toward the diaphragm 11, and a dissociation action works via water on the skin surface with which the diaphragm 11 contacts.

In this way, by applying the pulsating voltage VF to the decay, electricity is applied from the surface of the skin to the various barriers of the underlying tissue and the intercellular binding moisture, and the ionization of moisture by energizing the subcutaneous tissue is reduced. Occurs.

Since the pulsating voltage VF is obtained by induction from the oscillating voltage applied to the ultrasonic vibrator 13, the pulsating voltage VF and the oscillating voltage or the vibration of the diaphragm 11 are completely synchronized, and the skin Electric current flows over a range, which is extremely effective for activating skin. FIG. 9 and FIG. 10 are diagrams C ′ showing an example of the state of the skin by using the ultrasonic cosmetic device 1.

As shown in Fig. 9, if the tip of the working part EF of the diaphragm 11 is pressed against the skin and used to scoop the surface of the skin with the diaphragm 11, the ultrasonic vibration The cleaning liquid is turned into a mist, and dirt on the pores PR is instantly emulsified and washed, and old dead skin cells are easily removed. As a result, the surface of the skin is refreshed. Also, as shown in Fig. 10, when the back surface of the working portion EF of the diaphragm 11 is pressed against the skin, it penetrates to the deep part of the mist fluidized by the ultrasonic vibration, The skin is activated by the sound wave vibration. The result is a moist and strong ^ r.

The operation and effects of the ultrasonic beauty device 1 are as follows. (1) The vibration mechanism 7 that vibrates ultrasonically is housed in the casing 21 and has a plow shape, making it easy to use for treatment.

(2) Ultrasonic vibration is applied to the skin of the subject by the diaphragm 11, and at the same time, a pulsating voltage VF is applied by interposing water on the treated surface of the skin, so that water is dissociated by the dissociation action. This acts on the skin prisoners.

(3) A curved surface and an arc are formed on the working part EF of the diaphragm 11 and the working part EF of the diaphragm 11 performs tanning, scuffing, scooping, rubbing, stroking, etc. on the skin. Can be cleaned and cleaned, which is effective for beauty and beauty.

夕 Evening and patting are performed on the curved surface of diaphragm 11, and the scriber of the skin surface is performed at the tip of the back of the curved surface. Also, due to the cushioning effect of the curved surface, softness, vibration and vibration can be obtained mechanically.

切り替える By switching the switching switch 209 to the intermittent mode side, the ultrasonic vibration is intermittently driven while turning on the water, and the “sunset” effect on the skin can be obtained. A stimulus for metabolic activity can be transmitted.用いる When applying cosmetics, after applying an appropriate amount of cream on the surface of the skin such as the face or hands, move the cream on the skin while pressing the cream with the action part EF of the diaphragm 11. As a result, the penetration of the cream into skin / S becomes extremely good, and the subcutaneous tissue of J ^ is activated by vibrating.

には To remove the used cream, move it while pressing the surface of the skin with the tip of the working section EF of the diaphragm 11. If the surface of the skin is dry, apply water or oil to the working part EF so that the ultrasonic vibration can be efficiently transmitted to the skin.

In the above embodiment, one pole of the pulsating current voltage VF is connected to the subject by the wristband WB, but an appropriate clip may be used. It may be connected to more than one target person. The connection point can be appropriately selected such as an arm, an earlobe, or a shoulder. In addition, the whole or each of the vibration mechanism 7, the main body 3, the control device 4, or the ultrasonic beauty device 1 The configuration, shape, material, dimensions, number, and the like of the parts can be appropriately changed in accordance with the gist of the present invention. Industrial applicability

As described above, the ultrasonic cosmetic method and apparatus according to the present invention can further activate the skin by more effectively applying an electric current to the skin in addition to the mechanical vibration by the diaphragm. It is useful for the beauty and health industries that promote beauty and health.
