  Hereinafter, the present invention will be described in more detail based on embodiments. FIG. 1 shows the appearance of the ultrasonic cosmetic device 1 of the embodiment. The probe head 10 with a top is provided with a grip body 30 that supports the probe head 10 on one side. The outer surface of the top plate 11 of the probe head 10 is a skin contact surface 12, and the skin contact surface 12 can be brought into close contact with the skin by holding the gripping body 30 in hand.

  The top plate 11 of the probe head 10 has a thickness capable of ultrasonic vibration, and a circular opening 13 is formed at the center. In order to ultrasonically vibrate the top plate 11, the ultrasonic transducer 20 provided on the inner surface side of the top plate 11 has a central hole 21 corresponding to the opening 13 of the top plate 11 as shown in FIG. 3. It has a ring shape. A drive circuit for driving the ultrasonic transducer 20 is provided inside the gripping main body 30, and a lead wire drawn from the drive circuit and electrodes provided on the front and back of the ultrasonic transducer 20 are connected. The details are not shown in the figure. A switch 31 for turning on and off the drive circuit is provided on the surface of the grip body 30.

  The probe head 10 is made of metal (for example, aluminum die cast), the top plate 11 is electrically conductive, and the skin contact surface 12 constitutes one electrode 41. The other electrode 42 that forms a pair with this one electrode 41 as one electrode is provided along the back portion of the gripping body 30.

  The circuit shown in FIG. 2 for energizing a small voltage pulse train through the one electrode 41 and the other electrode 42 is also provided inside the gripping body 30. In FIG. 2, reference numeral 43 is a small voltage pulse oscillation circuit, 44 is a power supply circuit, and 45 is a switch. The switch 45 is provided side by side with the switch 31 provided on the surface of the grip body 30. When the skin contact surface 12 as one electrode 41 is in contact with the skin and the other electrode 42 provided on the back portion of the gripping body 30 is in contact with the hand in a state where the switch 45 is turned on, an oscillation circuit for a small voltage pulse The voltage of the power supply circuit 44 is applied to 43. When a voltage is applied to the small voltage pulse oscillation circuit 43, a small voltage pulse train flows between the electrodes 41 and 42 through the subcutaneous tissue. The small voltage pulse train has a pulse width of 500 microseconds to 5 milliseconds, a duty ratio of 50% or less, a repetition frequency of 50 to 400 Hz, and a peak voltage value of 0.05 to 20 volts, respectively. Are set in advance.

  When the ultrasonic cosmetic device 1 of the embodiment configured as described above is used, the grip body 30 is held in the hand with the switch 31 and / or the switch 45 turned on, and the skin contact surface of the probe head 10 Make 12 touch the skin.

  When the switch 31 is turned on, the ultrasonic vibrator 20 vibrates, and ultrasonic vibration is applied to the skin from the skin contact surface 12 to obtain a certain cosmetic effect. FIG. 4 shows the state of ultrasonic vibration of the skin contact surface 12. In the figure, (a) shows a conventional probe head 10A, and a disc-shaped ultrasonic transducer 20A is provided on the inner surface side of the top plate. On the other hand, (b) represents the probe head 10 of the embodiment. In the case of the conventional probe head 10A, since the ultrasonic transducer 20A has a disc shape, the ultrasonic wave 51 applied to the skin 50 has the largest amplitude at the center of the probe head 10A and moves toward the outer edge of the probe head 10A. The amplitude tended to decrease gradually. For this reason, the intensity | strength of the ultrasonic wave 51 given to skin from the outer edge part of a skin contact surface is weak, and it was difficult to acquire sufficient cosmetic effect. On the other hand, in the probe head 10 of the embodiment, the opening 13 is formed in the center of the top plate 12 and the ultrasonic transducer 20 is configured as a ring shape. 51 becomes concentric, and the outer edge portion of the skin contact surface 12 can have a larger amplitude than the central portion. As a result, when the outer edge portion of the probe head 10 is in contact with a fine portion such as the eyes, the ultrasonic vibration sufficient to enjoy the cosmetic effect can be received on the fine portion. Therefore, care can be taken to every corner of the skin.

  When the switch 45 is turned on so that the skin contact surface 12 comes into contact with the skin, the subcutaneous tissue of the skin is between the one electrode 41 configured on the skin contact surface 12 and the other electrode 42 provided on the gripping body 30. A small voltage pulse train will flow through. By energizing the small voltage pulse train, it promotes skin pigmentation (whitening) and skin regeneration, facilitates the transmission of synaptic signals acting on peripheral nerve synapses, promotes skin rejuvenation, and transdermally absorbs serum. Can be smooth.

  Both the switch 31 and the switch 45 are turned ON so that both the cosmetic effect by applying the ultrasonic vibration and the cosmetic effect by energizing the small voltage pulse train can be enjoyed. You may make it enjoy the beauty effect by application of an ultrasonic vibration, or the beauty effect by energization of a small voltage pulse train by turning ON 45.

  In the above embodiment, the surface of the skin contact surface 12 of the probe head 10 is plated with gold (Au) to cover the outermost surface of one electrode 41 constituted by the skin contact surface 12 with a gold film, A film of zinc-excess zinc oxide (ZnO: Zn) may be formed on the outer surface of the other electrode 42 provided on the gripping body 30 so as to cover the outermost surface. In this way, when one electrode 41 is brought into contact with the skin and the palm is brought into contact with the other electrode 42, a potential difference is generated between the electrodes 41 and 42 so that a body current flows. By operating the oscillation circuit 43 of a small voltage pulse with this internal current, it is possible to eliminate the power supply circuit 44 for the oscillation circuit 43 and to make a simple circuit configuration. If the power supply circuit 44 is eliminated in this way, electricity is not introduced into the skin by external power, so that it is possible to eliminate electrical allergies and chemical reactions and eliminate the risk of skin irritation.

  Further, a vibrator (not shown) may be installed in the probe head 10 so that the top plate 11 can be vibrated by the vibrator. By superimposing the vibration by the vibrator on the top plate which is ultrasonically vibrated, it is possible to give a pleasant stimulus (like massage) to the skin by the vibrator.

  FIG. 5 shows a portion of a probe head 10 according to another embodiment of the present invention. In this embodiment, the near-infrared light source 60 is provided so as to face the opening 13 formed in the top plate 11 and the central hole 21 of the ultrasonic transducer 20. (FIG. 1B also shows an approximate installation position of the near-infrared light source 60.) Near-infrared light can be irradiated from the near-infrared light source 60 through the central hole 21 and the opening 13 to the skin. . When skin is irradiated with near-infrared light in a state where the skin contact surface 12 subjected to ultrasonic vibration is in contact with the skin, the near-infrared light can be transmitted to the basal layer of the skin, and the erasure in the basal layer of the skin It can improve the local circulation of blood vessels. In addition, cosmetics applied to the skin can also reach the basal layer.
