JP6619962B2 - Skin cleansing device and sonic cosmetic device in beauty - Google Patents

Description

The present invention mainly relates to a skin cleansing device and a sonic cosmetic device for beauty in which the dirt on the skin of the human face and head is struck down.

  Patent Document 1 is proposed by the applicant. Conventionally, since this type of skin cleansing tool and sonic cosmetic device are multipurpose, there has been a problem that the structure is complicated. Therefore, there has been a demand for the appearance of “a skin cleansing device and a sonic cosmetic device that mainly scours dirt on the human face and head skin” with a “simple structure” without placing emphasis on the ion effect and temperature effect. . In that case, the thing which fully exhibits the cleansing effect is expected.

  Incidentally, Patent Document 2 exists as an invention using ultrasonic waves. Although this patent document 2 is related to the technical field of treatment and is not related to the technical field of the sonic cosmetic device like the present invention, it is, for example, a therapeutic method or ultrasonic therapeutic device for the purpose of killing cancer cells. The upper surface of one side of the disk-like sound projectile 7 of this ultrasonic therapy apparatus is formed as a concave lens-shaped curved surface (projection surface) 7a inward as a whole, and the concave lens-shaped curved surface (projection surface) 7a is in front of the human body. The focal point P of the ultrasonic wave emitted from the concave lens-like curved surface (projection surface) 7a through the bag-like cooling member 10 is outside the disc-like sound projectile 7, that is, the treatment site in the human body 3. (Where there are cancer cells / tumors). As described above, in the technical field of the therapeutic method or the ultrasonic therapy apparatus, although the disk-shaped sound projectile 7 having a concave lens-like curved surface (projection surface) 7a on one side is used, the focal point P on which the ultrasound is focused is It was located in the body (the reference is that of Patent Document 2).

When applied to intact skin in cosmetic cleansing equipment and ultrasonic cosmetic device of the above technique, it is impossible to obtain the pressure (vibration) to obtain a cleansing effect on the skin of the human face or head. Therefore, application of the technique described in Patent Document 2 is also expected in the technical field of beauty instruments. At that time, it is preferable not only the low-frequency signal or the high-frequency signal because of the problem of the invention. Accordingly, the present invention has appeared in view of such demands and expectations.

It is formed in a flat shape that is crushed. Of course, the size, length, thickness, etc. of the three-dimensional shape of the gripping portion 1 are preferably formed in a shape that is easy to grip with one hand, for example, the back wall side is formed in an arc shape that fits the palm, Most preferably, the front wall side is narrowed toward the center.

  Further, the front wall of the distal end portion 2 is formed with an opening 4 having a substantially circular upper surface direction or a slightly inclined direction, and the lower end portion of the skin cleansing tool Y is integrally fitted in the opening portion 4. . This fitting means (for example, tight fitting, engagement, screwing, etc.) and a means for fixing integrally (for example, a fixing tool, an adhesive, etc.) are not particularly limited.

  By the way, one or more (embodiment) operation units 5 are provided at appropriate positions on the front wall of the gripping portion 1, and one operation unit 5 serves as a switch for turning on / off the main power supply at least. . In another embodiment, the operation unit 6 includes three or more transmitters in the drive unit, and there are a plurality of combinations thereof.

  Further, a power input terminal portion 7 (see FIG. 5) for connecting a power output terminal of an AC (alternating current) adapter is provided on the lower edge portion of the grip portion 1. Although not particularly illustrated, a single or a plurality of display units (for example, LEDs) may be provided at appropriate locations such as the front wall and the back wall of the grip portion 1 as is well known.

  Next, FIG. 2 is an exploded explanatory view of the members constituting the skin cleansing tool Y, and the lower member of FIG. 2 depicts a sound wave element body 11 capable of emitting sound waves, and above the sound wave element body 11. The member is a metal sound wave irradiation base 21, and the member drawn above the sound wave irradiation base 21 is a cover-like vibration medium 31 formed in a cap shape.

  First, the configuration of the acoustic wave element body 11 will be described. The acoustic wave element body 11 of the present embodiment uses a piezoelectric element (piezo element). As is well known, a piezoelectric element is a kind of ferroelectric substance that generates a voltage when a force such as vibration or pressure is applied, and generates a sound wave when a voltage is applied, for example, for an ultrasonic motor. They are used as piezoelectric elements, piezoelectric bimorph elements, laminated voltage actuators, high-frequency vibrators, and the like.

  Since the object of the present invention is to cleanse the skin of the human body, mainly the human face and head skin (cleansing), the voltage element generates sound waves when a voltage is applied to a pair of counter electrodes simultaneously. It is used as a sound wave oscillator that emits (including ultrasonic waves). Therefore, as shown in FIG. 2, the sonic element body 11 is processed into a disk shape, for example, and a crystal of lead titanate and lead zirconate, which is a ternary metal oxide (referred to as “lead zirconate titanate”). Voltage element body 12, thin plate-like or film-like first electrode 13 and second electrode 14 fixed on both surfaces (upper surface and lower surface) facing each other in the thickness direction, and first of these It consists of a pair of cables 15 and 16 connected to the electrode 13 and the second electrode 14, respectively. When the same voltage is applied simultaneously to the electrodes 13 and 14, the first electrode 13 and the second electrode 14 correspond to the frequency. As a result, the sound wave 17 is emitted toward at least the sound wave irradiation base 21. The internal structure of the sonic element body 11 is a matter that can be designed appropriately.

  Next, the configuration of the metal sound wave irradiation base 21 will be described. As shown in FIGS. 2 and 3, the sonication pedestal 21 has a polygonal or circular plate shape (disk shape) with a little thickness, and the thickness of the circular peripheral end 23a is the center, for example. The thickness gradually decreases toward the portion 25a. In the present embodiment, the one side lower surface 22, the one side upper surface 23 opposite to the one side lower surface, the peripheral side surface 24 substantially orthogonal to the one side upper surface 23 and the one side lower surface 22, and the one side upper surface 23. And a recess 25 having a substantially arc-shaped cross section.

  Thus, the one-side lower surface 22 is a surface that is fixedly joined to the first electrode 12 of the acoustic wave element body 11. On the other hand, the one side upper surface 23 and the peripheral side surface 24 including at least the recess 25 are outer wall surfaces to which the inner wall surface of the cap-shaped cover-like vibration medium 31 is joined in a close contact state, so that the outer wall surfaces 24, 23, Reference numeral 25 denotes a mounting portion to which the cover-like vibration medium 31 is externally fitted.

  The thickness, material, size, and the like of the metal sound wave irradiation base 21 are preferably aluminum in consideration of the propagation speed of the sound wave 17, the corrosion resistance, and the like. Of course, materials such as stainless steel can also be used. The radius of curvature of the recess 25 having a substantially arc-shaped cross section of the sound wave irradiation base 21 is such that the sound wave 17 emitted from the sound wave element body 11 is near the surface of the filling portion of the cover-like vibration medium 31 described later or the surface in the filling portion. It is set appropriately so as to be located either (see FIG. 6). Further, the entire outer surface including the lower surface on one side of the sound wave irradiation base 21 is appropriately surface-treated by a known means.

Next, the configuration of the cover-like vibration medium 31 will be described with reference to FIGS. 2 and 4, for example. The cover-like vibration medium 31 is fixed to the outer surface of the metal acoustic wave irradiation base 21 through, for example, an adhesive layer. Thus, the cover-like vibration medium 31 is formed in a cap shape made of a resin material having a sound wave transmission rate different from that of the sound wave irradiation base 21, and the curved surface contact of the recess 25 having the substantially arc-shaped cross section of the sound wave irradiation base 21. A filling portion 32 filled in the recess 25 having a substantially arc-shaped cross section in contact with the surface 25a, and a ridge shape extending outwardly from the filling portion, and at least one side upper surface 23 of the sound wave irradiation base 21 A slightly flat peripheral end portion 33 that covers the entire surface, an elastic annular peripheral wall portion 34 that extends substantially perpendicularly downward from the slightly flat peripheral end portion, and a lower edge portion of the annular peripheral wall portion in a horizontal direction. It has an elastic annular bottom wall portion 36 that is continuous in an orthogonal state and has an opening 35 into which the sound wave irradiation base 21 can be fitted.

  As shown in FIG. 6, the cover-like vibration medium 31 converges the sound wave 17 irradiated from the sound wave irradiation base 21, and the surface 32 a of the filling portion 32 including the focal point P is the skin of the face and head. For those skilled in the art, a thick block form in which the sound wave element body 11, the sound wave irradiation base 21, and the cover-like vibration medium 31 are integrally coupled in the vertical direction. Can also be referred to as “ultrasonic transducers”, “acoustic lenses” and the like.

  In the embodiment, in consideration of the incidental object of the present invention, the elastic acoustic peripheral wall 34 and the elastic annular bottom wall 36 are provided so that the metal sound wave irradiation pedestal does not directly touch the living body skin. However, since the elastic annular bottom wall portion 36 is supported by a support piece (not shown) provided on the inner wall surface of the opening of the housing 3, it has the effect of preventing the cover-like vibration medium 31 from being displaced or removed. Although it is preferable from the viewpoint, it is not always necessary.

  In addition, the cover-like vibration medium 31 is formed in a cap shape so as to cover at least the one side upper surface 23 of the metal sound wave irradiation base 21 and the peripheral side surface 34 substantially orthogonal to the one side upper surface, and the material thereof is silicon rubber. It is. For the main purpose of the present invention, preferably, at least the surface of the filling portion 32 of the cover-like vibration medium 31 is either a convex lens-like curved surface or a dome shape as a whole, and the focal point P is the surface 32a of the filling portion. Or it is located somewhere near the surface in the filling portion.

  Next, the control system of the sonic cosmetic device X will be briefly described with reference to FIG. The three-dimensionally shaped housing 3 is activated based on an operation signal from at least one or a plurality of operation units 5, and is driven based on a command signal from the control means 41 so that the skin cleansing tool Y And an internal power source (for example, a secondary battery) 45 that can be charged. As described above, the power input terminal portion 7 is appropriately provided.

  The control means 41 has a storage unit 44 for storing a program and a timer 43. If it adds, the memory | storage part 44 of the control means 41 will incorporate the processor, RAM, and ROM which perform the overall control of the sonic cosmetic device X and various calculations. The ROM stores software for control and computation to be executed and software such as various parameters. The processor reads the software from the ROM, interprets the command statement, and executes the command using the memory space of the RAM. To do. The timer 43 determines the operation time of the control means 41 based on, for example, an operation signal from the operation unit 5, and sends a command signal from the control means 41 after a predetermined time of 5 minutes, 7 minutes, 10 minutes, or the like. Used to stop. Therefore, as a function of the software of the control means 41, cleansing can be automatically terminated as described above.

  Further, as shown in FIG. 7, the control means 41 intermittently generates high-frequency ultrasonic waves on the pair of electrodes 13 and 14 of the acoustic wave element body 11 via the drive unit (for example, intermittent oscillator) 42, and the intermittent The portion is controlled so as to give a drive signal having a low frequency interval to the acoustic wave element body.

The drive unit includes at least an intermittent transmitter 42, and the control means 41 intermittently generates high-frequency ultrasonic waves by the intermittent transmitter 42, and the intermittent portion is driven at a low frequency interval, for example. More specifically, the drive unit 42 includes an intermittent oscillator 42, and the control unit 41 uses the intermittent transmitter 42 to generate high-frequency ultrasonic waves (for example, 1 MHz). Is generated intermittently, and the intermittent signal is generated at a low frequency interval, for example, a driving signal S having a frequency of 10 Hz (0.1 second, 0.2, 0.3 second, etc.) as one acoustic wave element. Control to give to the body 11.

  Here, in this embodiment, the sound wave element body 11 itself has a resonance frequency (natural frequency), and in the sound wave element body 11 (ultrasonic vibrator) used in this embodiment, the value is 1 MHz. It has become.

  The numerical values of the above-described frequencies (that is, high-frequency ultrasonic waves and low-frequency intervals) do not necessarily have critical significance (optimal numerical values), but the low-frequency intervals, for example, as described above, “ On the other hand, the high frequency ultrasonic wave is, for example, “1 MHz (10,000 times the low frequency)” as described above. In view of the problems of the invention, it is desirable that high-frequency ultrasonic waves are high in each stage with respect to low-frequency intervals. In the embodiment, high frequency ultrasonic waves (for example, 1 MHz) are made into a substantially sine wave shape with respect to one acoustic wave element body 11, and intermittently at low frequency intervals (for example, 10 Hz (0.1 seconds)). Although generated, the low frequency interval is not limited to the example of 10 Hz (0.1 second), and for example, “0.3 second”, “0.4 second”, “0.5 second”, “0. You may make it change repeatedly with the period in substantially 1 second range, such as "6 second" and "0.7 second."

  Further, in the case where high frequency ultrasonic waves are intermittently generated at low frequency intervals within a range not departing from the object of the invention, the combination of the numerical values of the high frequency and the low frequency is limited to the numerical values of the above-described embodiments. However, other numerical values may be used, and the same effect can be obtained even when an experiment is performed and a plurality of optimum combinations are performed. Furthermore, it is possible to provide a plurality of acoustic wave element bodies 11 depending on the embodiment.

  Finally, FIG. 8 is an explanatory view showing an example of a usage mode of the sonic cosmetic device X. At the time of use, for example, “Cotton 50 (not a specific requirement of the invention)” is appropriately attached to the skin cleansing device Y provided at the tip of the sonic cosmetic device X, and the center portion (center portion) of the cover-like vibration medium 31 is attached. Use it with your face or head in contact. When the drive signals a and b (alternating alternating voltage) from the drive unit (oscillator) 42 are low-frequency signals L, it feels like tapping “ton-ton-ton-ton”, on the other hand, high frequency as ultrasonic waves In the case of the signal H, it feels as if it is struck quickly and strongly with “Don Don Don”, and the “cleansing effect (vibration pressure)” can be sufficiently exerted.

In the embodiment, the skin cleansing device Y and the sonic cosmetic device X do not include a temperature sensor at an appropriate place, but the temperature sensor may be a constituent requirement. In the case of the embodiment in which the temperature sensor is added, a temperature sensor (not shown) is fixedly disposed on the inner wall surface or the outer wall surface of the cover-like vibration medium 31 of the skin cleansing tool Y, for example. A temperature threshold value (for example, 40 degrees) may be set in the storage unit 43, and the driving of the sonic cosmetic device X may be automatically stopped when the temperature of the cover-like vibrating medium 31 exceeds the temperature threshold value. . Of course, it is preferable to design the cover-like vibration medium 31 so that the temperature does not exceed 40 degrees, for example.
Next, FIGS. 9 and 10 are explanatory views showing a second embodiment of the present invention. In the description of the second embodiment, the same parts as those in the first embodiment are denoted by the same or similar reference numerals, and redundant descriptions are omitted.

  FIG. 9 is an explanatory view of the skin cleansing tool Y1 of the second embodiment, and FIG. 10 is a perspective view of the cover-like vibration medium 31A of the skin cleansing tool Y1. As is apparent from a comparison of the shape of the surface of the cover-like vibrating medium 31A of the second embodiment and the surface of the cover-like vibrating medium 31 of the first embodiment, the curvature of the radius of the surface of the cover-like vibrating medium 31 of the first embodiment. However, the cover-like vibration medium 31A of the second embodiment is larger than that of the first embodiment, for example, like a hemispherical surface, whereas it is gentle like a dome shape and slightly arcuate. In this case, within the range that does not depart from the object of the invention, the vicinity of the top of the cover-like vibration medium 31A may be slightly flat and may be a so-called “substantially spherical trapezoidal shape”. When the surface of the cover-like vibration medium 31A is formed like a hemispherical surface, as a matter of course, the size of the radius of the recess 25 of the metal sound wave irradiation base 21A is preferably set so that the focal point P is the surface of the filling portion. Or it changes so that it may be located in the vicinity of the surface in a filling part.
