First, when the switch 15 shown in FIG. 2 is pressed once, the LED 21 is turned on to indicate that the main unit power is turned on, and the first ultrasonic transducer 75 of the first head unit 5 capable of caring the nose. Vibrates ultrasonically and transmits this vibration to the first probe head 9.

  If 5 minutes have passed after the switch 15 is pressed once, the main power is automatically turned off. If the switch 15 is pressed again within 5 minutes, the first probe head that has been operating until now The ultrasonic vibration 9 stops and the second ultrasonic transducer 107 of the second head unit 7 capable of caring for the face ultrasonically vibrates, and this vibration is transmitted to the second probe head 13 and simultaneously vibrates. The motor 143 is also driven. At this time, the LED 23 is turned on, while the LED 21 is turned off.

  If 6 minutes elapses in this state, the main body power supply is automatically turned off. However, if the switch 15 is pressed again within 6 minutes, the vibration motor 143 stops and only the second ultrasonic transducer 107 is turned on. It operates to continue the ultrasonic vibration of the second probe head 13. At this time, the LED 25 is turned on, while the LED 23 is turned off.

  In this state, the switch 15 is further pressed once, or the second probe head 13 is in a state where no movement load is applied to the skin for 2 minutes and 30 seconds, or the second probe head 13 is pressed against the skin for 10 minutes for skin care. Is performed, the main body power is turned off and the LED 25 is turned off.

  As described above, in this ultrasonic beauty instrument, the first head unit 5 and the second head unit 7 can be selectively operated by operating the switch 15 provided in the main body unit 1.

  Further, in the present embodiment, when the first probe head 9 or the second probe head 13 is operated, the same ultrasonic frequency is supplied from the same control circuit in the transducer control circuit board 36. Miniaturization of the entire device can be achieved.

  Furthermore, according to the present ultrasonic beauty instrument, as shown in FIG. 1, the first and second head parts 5 are formed in a state where the user naturally holds the main body part 1 by making the whole into a Y shape. The contact surfaces 9a and 13a of the first and second probe heads 9 and 13 provided at the distal ends of the first and second probes 7 and 7 can be easily brought into contact with the skin surface.

    Next, the operation for caring for the nose using the first head unit 5 shown in FIG. 6 will be described. The first probe head 9 is ultrasonically vibrated by holding the main body 1 and pressing the switch 15 once as described above. In this state, the first head unit 5 is moved closer to the upper part of the nose (near the area between the eyebrows) and pressed. At this time, the notch 11 a of the attachment 11 is positioned at the lower part. When a pressing load of a certain level or more is applied through the attachment 11 in this state, the attachment 11 moves backward while resisting the elastic force of the probe head spring 83.

  Here, the inner diameter of the skin contact portion 11a of the attachment 11 is 17.0 mm, and the outer diameter is 20.0 mm. As an example, FIG. 9 shows a cross-sectional view when the attachment 11 is retracted 1.5 mm. When the attachment 11 and the first probe head 9 to which ultrasonic vibration is applied are in contact with the skin and are in a state as shown in FIG. 9, dirt components of the square plugs and pores are caused by the ultrasonic vibration of the first probe head 9. Softens and can push them to the skin surface.

  In this state, the instrument is gradually slid toward the tip of the nose, so that the pushed-out and softened plugs and dirt components of the pores are removed by peeling off the inner periphery of the attachment 11. At this time, the attachment 11 has a notch 11a on the front side in the advancing direction, and the inner peripheral edge that contacts the nose on the opposite side of the notch 11a has an R shape. At the same time, the effect of tightening the pores after removal can be obtained by ultrasonic vibration.

  Moreover, since the attachment 11 is circular, there is no problem even if the moving direction is changed. Since such an attachment 11 can be removed, it can be washed with water in a detached state, and can be used in a clean state with improved cleanability.

  The retraction amount (float amount) at the time of pressing the attachment 11 is preferably about 2.0 mm at the maximum. At the maximum retraction, the inner surface of the attachment 11 contacts the tip of the probe cover 77 at the contact portion P. It shall touch. In addition, the protrusion amount α from the contact surface 9a of the ultrasonic transducer 9 during use is desirably 0.3 mm or more, and preferably 0.5 mm.

  When the float amount exceeds 2.0 mm, the stroke when pressed against the skin becomes large and usability deteriorates. When the projection amount α during use exceeds 0.5 mm, the first ultrasonic vibration The child 9 becomes difficult to contact the skin.

  In addition, the pressing load of the attachment 11 is preferably 0.686N to 1.078N, and more preferably 0.784N to 0.98N.

  The attachment 11 described above has a structure that can be floated by the probe head spring 83. However, the attachment 11 may have a fixed structure, and may have a plate shape instead of a circular shape.

  Next, the operation of performing facial care using the second head unit 7 shown in FIG. 17 will be described. As described above, when the switch 15 is pressed once again while the first head unit 5 is operating, the second probe head 13 is ultrasonically vibrated and the vibration motor 143 is activated to generate a vibration function. To do. In this state, the second head portion 7 is brought close to, for example, the cheek of the face portion and pressed.

  By applying the ultrasonic vibration of the second probe head 13 and the vibration function of the vibration motor 143, the pores are stretched to promote blood circulation, promote the production of collagen, and the skin is stretched to make the pores conspicuous. Make it disappear.

  Here, when a certain load or more is applied to the second probe head 13 against the skin, the head spring 141 is bent and the second probe head 13 is retracted as shown in FIG. At this time, the head base 113 is also retracted integrally, the boss portion 113d bends the rubber cover 129, and the head stopper 131 and the vibration motor 143 are also retracted integrally.

  Further, when the device is moved along the skin surface, as shown in FIG. 22, the whole of the integrally retracted portion is inclined so that the contact surface 13 a of the second probe head 13 is moved to the skin surface. Can always be in a natural state.

  At this time, since the spring cover 139 made of an elastic material such as EPDM is provided, even if the head base 113 and the spring base 127 interfere with each other, the spring cover 139 absorbs the lateral vibration by the vibration motor 143. The generation of abnormal noise can be prevented. Therefore, skin care can be performed without an uncomfortable feeling due to unpleasant sounds.

  Further, as shown in FIG. 6, in the first head portion 5 described above, the first probe head 9 is arranged on the probe base 91 to which the connection fittings 95 and 97 are attached, and the probe cover 77 is put on this assembly part. By fixing the probe base 91 and the probe cover 77 with the screws 93, the first probe head 9 is pressed against the probe base 91, whereby the contact pieces 95a and 97a of the connection fittings 95 and 97 are bent. The lower surface of the flange 9d of the first probe head 9 and the second ultrasonic transducer 75 are in contact with each other. For this reason, this contact state is maintained well, and the electrical signal from the main body circuit board 35 can be stably transmitted to the first ultrasonic transducer 75.

  Further, as shown in FIG. 15, each of these connection fittings 95 and 97 is isolated by a cross-shaped insulating rib 91g, so that contact with each other can be reliably avoided, and a short circuit between the connection fittings 95 and 97 is prevented. Thus, problems such as breakage of the control circuit can be prevented.

  In the first head portion 5 described above, when skin care is performed using a liquid such as a gel, the liquid tries to enter the first probe head 9 and the attachment 11, but the O-rings 79 and 89 Therefore, it is possible to prevent this intrusion and ensure a good use state. Further, since such a waterproof structure is provided, the liquid or solid adhering to the first probe head 9 or the parts surrounding it can be washed with water, and the main body control circuit can be prevented from being damaged.

  On the other hand, when skin care is performed using the liquid such as gel in the second head portion 7, the liquid tries to enter the second probe head 13 and the head cover 109, but the O-rings 111 and 115. The rubber cover 129 and the O-ring 130 can prevent this intrusion and ensure a good use state. Further, since such a waterproof structure is provided, the liquid or solid adhering to the second probe head 13 or parts surrounding it can be washed with water, and damage to the main body control circuit can be prevented.

  Further, when skin care is performed using a liquid such as a gel using this instrument, the liquid tries to enter the main body through the head cases 65 and 67 and the housing 31 shown in FIG. The ring 63, the switch rubber 51, and the lower cover O-ring 57 can prevent this intrusion and ensure a good use state.

  Therefore, in this case as well, liquids and solids adhering to the parts surrounding the main body 1 can be washed with water, and damage to the main body control circuit can be prevented.

  In the second head portion 7 shown in FIG. 17, the head stopper 131 for attaching the vibration motor 143 and the circuit board 125 is fixed to the boss portion 113 d of the head base 113, and these are integrated with the spring base 127. Accordingly, the motor lead wire 147 that connects the vibration motor 143 and the circuit board 125 and that is formed relatively thin can be prevented from breaking.

  In place of the motor lead wire 147 connecting the vibration motor 143 and the circuit board 125, contact between the connection fittings provided on the vibration motor 143 and the circuit board 125, or connection fitting provided on the vibration motor 143 is used as the circuit board. It may be configured to contact the plated contact on the 125 side.
