By inserting the lower part of the housing 11 into a charging stand (not shown), the electrical contacts of the charging terminal portion 25 come into contact with the electrical contacts of the charging stand, and the electric power supplied from the charging stand via the electrical contacts powers the inside of the housing. Rechargeable battery is charged.

The housing 11 is provided with hand electrodes 26 extending from both sides to the bottom. The hand electrode 26 is provided at a position where the hand touches the beauty device 1 when the user holds the beauty device 1 with the hand, and is an electrode that can be energized by touching the hand.

FIG. 2 is a diagram showing a part of the internal structure of the beauty device 1. As shown in FIG.
A contact plate 31 for supporting the diaphragm 12 , a vibrator 32 , and a substrate 33 to which the vibrator 32 is fixed are provided inside the housing 11 . The vibrator 32 is an ultrasonic actuator composed of, for example, a piezoelectric element, and the substrate 33 is, for example, a glass epoxy substrate. The contact plate 31 supports the diaphragm 12 on one side at one end and is attached to the substrate 33 at the other end.

In the drawings and the following description, the horizontal direction in FIGS. 1 and 2 is the X-axis direction, and the vertical direction is the Y-axis direction. A direction orthogonal to a plane including the X-axis and the Y-axis, that is, a vertical direction with respect to the paper surface of FIGS. 1 and 2 is defined as a Z-axis direction. Hereinafter, X-axis direction and Y-axis direction. The Z-axis direction is simply referred to as the X-direction, Y-direction, and Z-direction.

The Y direction is the direction from the distal end side of diaphragm 12 toward vibrator 32 , that is, the longitudinal direction of diaphragm 12 . The X direction is the width direction of the diaphragm 12, that is, the lateral direction. In the figure, the X direction, Y direction, and Z direction are indicated by arrows. An "x" indicates an arrow pointing from the front to the back of the paper.

Diaphragm 12 , one end of which is supported by contact plate 31 , is provided with the other end extending to the outside of housing 11 . The diaphragm 12 is made of a metal such as a thin elastic stainless steel plate or a hard thin copper plate. The contact plate 31 is made of a hard and thick stainless steel plate or a metal such as an aluminum or duralumin plate, and reinforces the portion of the diaphragm 12 on the vibrator 32 side so that the vibration of the vibrator 32 is transferred to the distal end side of the diaphragm 12 . It works to focus on

A center line C along the longitudinal direction (Y direction) of the diaphragm 12 is arranged so as to coincide with the center lines of the contact plate 31 and the vibrator 32 . In this embodiment, the vibration generated by the vibrator 32 is displaced in the Z direction (the direction orthogonal to the plane including the longitudinal direction and the lateral direction of the diaphragm 12), and the diaphragm 12 is , oscillate along the Z direction.

The diaphragm 12 is composed of a flat portion 121 positioned on the vibrator 32 side and a curved surface portion 122 positioned on the distal end side. The flat portion 121 is formed as a flat surface with almost no undulations with respect to a plane (hereinafter referred to as an XY plane) including the longitudinal direction (Y direction) and the lateral direction (X direction) of the diaphragm 12 . The curved surface portion 122 has a curved surface protruding in the Z direction with respect to the XY plane.

The curved surface portion 122 of the diaphragm 12 has a curved outer periphery, and as shown in FIG. 2, there is a position where the width in the lateral direction (X direction) is the maximum value W1. The width gradually decreases toward the vibrator 32 side from the position where the width is the maximum value W1, and there is a position where the width is the minimum value W2 in the flat portion 121 .

Let L0 be the distance in the Y direction from the tip of the diaphragm 12 to the center of the vibrator 32, and L1 be the distance in the Y direction from the tip of the diaphragm 12 to the position where the width is the minimum value W2. L1 is preferably set to a value of 30% to 70% of the distance L0. As described above, the position where the width of the diaphragm 12 is the minimum value W2 should be set to the tip side of the diaphragm 12 or a position distant from the vibrator 32 side to some extent. Vibration energy transmission efficiency is improved.

FIG. 3 is a side view showing the structure of diaphragm 12. As shown in FIG. A curved surface portion 122 on the tip side of the diaphragm 12 has a convex surface 122a protruding in the Z direction. In FIG. 3, the curved surface portion 122 has a protruding convex surface 122a when viewed from below, but a concave surface 122b corresponding to the convex surface 122a can be seen when viewed from above.

The thickness of diaphragm 12 is preferably 0.5 mm to 1 mm. The thickness of the flat portion 121 and the thickness of the curved portion 122 (the distance between the convex surface 122a and the concave surface 122b) may be the same or different, but both thicknesses are 0.5 mm to 1 mm. is preferably

The convex surface 122a of the curved surface portion 122 has a region 122a1, which is a region where the inclination rises in the Z direction from the front end side to the rear end side (the vibrator 32 side), and and a region 122a2, which is a region where the slope rises in the Z direction. In this embodiment, the convex surface 122a is formed such that the inclination of the region 122a1 with respect to the XY plane is greater than the inclination of the region 122a2 with respect to the XY plane. With such a configuration, attenuation in the region 122a2 of the vibration energy transmitted from the vibrator 32 side to the tip portion of the diaphragm 12 can be suppressed.

FIG. 4 is a front view showing the configuration of diaphragm 12. As shown in FIG. In FIG. 4A, the outer periphery of the diaphragm 12 when viewed from the front includes regions 12r and 12s having curved shapes on the tip side of the curved surface portion 122, and width from the position where the width is the maximum value W1 to the rear end side. has a region 12t where the width gradually decreases and a region 12u where the width gradually increases from the position where the width is the minimum value W2 toward the rear end side. The region 12t is a region spanning the curved surface portion 122 and the flat portion 121. As shown in FIG.

The width W2 in this embodiment is preferably 50% or more of the width W1. This is because when the width W2 is less than 50% of the width W1, the vibration energy transmitted from the vibrator 32 is excessively damped, and the vibration at the tip of the diaphragm 12 is too small. The width W1 is preferably 5 mm to 20 mm, more preferably 12 mm to 17 mm. In the region 12u, there may be a position where the width of the diaphragm 12 is the maximum value W1 or greater than the maximum value W1.

The outer periphery of the distal end portion of the curved surface portion 122 having the regions 12r and 12s has a shape close to an ellipse. side) is preferably greater than the curvature of the periphery in the region 12s. With such a configuration, the magnitude of vibration at the tip of diaphragm 12 can be ensured.

FIG. 4B is a diagram for explaining transmission of vibration in the diaphragm 12. As shown in FIG. In the diaphragm 12, the vibration energy from the vibrator 32 is transmitted from the rear end side (lower side in the figure) to the front end side (upper side in the figure). Vibrational energy then gradually attenuates in the process of transmission. An elliptical region P of the curved surface portion 122 in FIG. 4B is a region that hardly vibrates compared to other regions. That is, in the process of transmitting the vibrational energy from the rear end side to the front end side, it is considered that the region P hardly transmits the vibrational energy. Therefore, the amount of attenuation of vibration energy can be suppressed.

More specifically, in a region where the width of diaphragm 12 widens from the rear end side to the front end side of diaphragm 12 in curved surface portion 122, concave surface 122b gradually becomes deeper toward the front end side (see FIG. 3). , the region P in which it is difficult to vibrate gradually expands. Therefore, in this region, the range in which the vibrational energy transmitted toward the distal end side of the peripheral portion excluding the region P can be gradually narrowed toward the distal end side. Vibrational energy is dispersed and is not attenuated even if the tip gradually expands, and the vibration can be reliably transmitted to the most advanced position. In addition, by providing a region where the concave surface 122b gradually deepens toward the distal end side, it is possible to prevent the propagated vibrational energy from being reflected by the concave surface 122b. can.

As described above, in the present embodiment, by forming the curved surface portion 122 having the convex surface 122a on the diaphragm 12, it is possible to create the region P, which is a region in which almost no vibration occurs. It is possible to obtain the effect of being able to suppress the attenuation of the vibration energy applied.

The control unit 41 includes, for example, a circuit board having a CPU (Central Processing Unit), a drive board for controlling each motor, and the like. The CPU controls the operation of each member in the beauty device 1 by executing processing according to a stored program.

The power supply unit 42 is electrically connected to the hand electrode 26 and the diaphragm 12, and energizes the hand electrode 26 and the diaphragm 12 as a pair. In this embodiment, the diaphragm 12 is made of metal and functions as an electrode paired with the hand electrode 26 . Further, the power supply unit 42 generates ultrasonic vibration by applying a voltage having a frequency in the ultrasonic range to the piezoelectric element of the ultrasonic actuator that constitutes the vibrator 32 .
The control unit 41 and the power supply unit 42 are provided inside the housing 11 .

Control by the control unit 41 will be described below.
The mode button 21 also serves as a power button, and when the control unit 41 detects that the user has pressed the mode button 21 for a long time, the control unit 41 controls the power supply unit 42 to turn on the power. .

When the mode button 21 is long pressed, the control unit 41 controls the power supply unit 42 to turn on the power supply unit 42 and causes the power supply unit 42 to start operating in the peeling mode. The controller 41 turns on the lamp corresponding to the peeling mode among the mode lamps 23 .

When the control unit 41 detects that the user has pressed the mode button 21 while the power supply unit 42 is operating in the peeling mode, the control unit 41 causes the power supply unit 42 to start operating in the moist mode. Then, the control unit 41 lights the lamp corresponding to the moist mode among the mode lamps 23 . Furthermore, when the control unit 41 detects that the mode button 21 has been pressed while the power supply unit 42 is operating in the moist mode, the control unit 41 causes the power supply unit 42 to start operating in the lift mode. Then, the control unit 41 lights the lamp corresponding to the lift mode among the mode lamps 23 .

As described above, the control unit 41 performs control to change the operation mode each time the mode button 21 is pressed. When the mode button 21 is pressed long in any operation mode, the control unit 41 controls the power supply unit to turn off the power, and turns off all the mode lamps 23 . The order of operation modes set each time the mode button 21 is pressed is not limited to the order described above, and may be set as appropriate. Also, it may be possible to set it by the user.

When the control unit 41 detects that the level button 22 has been pressed during operation in one of the operation modes, the control unit 41 causes the power supply unit 42 to perform control to change the vibration level of the diaphragm 12 . Then, each time the level button 22 is pressed, the vibration level is increased (or decreased).

Next, control in each operation mode will be described. In any operation mode, the user holds the beauty device 1, the vibration plate 12 is in contact with the skin surface, and the hand electrode 26 of the housing 11 is in contact with the user's hand. and

In the peeling mode, the power supply unit 42 applies a voltage of a predetermined frequency to the vibrator 32 to generate ultrasonic vibrations and transmit the vibrations to the distal end side of the diaphragm 12 . Further, the power supply unit 42 applies a voltage using the hand electrode 26 as a cathode and the diaphragm 12 as an anode to extract ions.

Since the diaphragm 12 is positively charged, dirt (old keratin, dust, etc.) charged with a negative charge adhering to the skin surface with which the diaphragm 12 is in contact can be adsorbed and discharged by the positive charge. can. The ultrasonic vibration of the vibration plate 12 imparts vibration to the skin surface, thereby promoting adsorption and discharge of dirt.

In the moist mode, the power supply unit 42 applies a voltage of a predetermined frequency to the vibrator 32 to generate ultrasonic vibrations and transmit the vibrations to the distal end side of the diaphragm 12 . Further, the power supply unit 42 applies a voltage using the hand electrode 26 as an anode and the diaphragm 12 as a cathode to introduce ions.

Since the vibrating plate 12 is negatively charged, the beauty essence attached to the skin surface is negatively ionized by contact with the vibrating plate 12, and is adsorbed to the skin surface and easily permeates deep into the skin surface. The ultrasonic vibration of the vibration plate 12 imparts vibration to the skin surface, thereby promoting the permeation of the beauty essence to the skin surface.

In the lift mode, the power supply unit 42 applies a voltage of a predetermined frequency to the vibrator 32 to generate ultrasonic vibrations and transmit the vibrations to the distal end side of the diaphragm 12 . Further, the power supply unit 42 applies a voltage between the hand electrode 26 and the diaphragm 12 to apply a weak current (microcurrent) to the skin surface in contact with the diaphragm 12 to care for the skin surface. Furthermore, the ultrasonic vibration of the vibration plate 12 is applied to the skin surface to care for the skin surface.

Then, the cosmetic device 1 is moved in the direction of the arrow while the tip of the vibration plate 12 is kept in contact with the skin surface S. By doing so, old keratin and dirt on the skin surface S can be removed by the vibration waves generated at the tip of the diaphragm 12 striking the skin surface S and ion derivation.

FIG. 6B is a diagram for explaining how to use the moist mode or the lift mode. In the moist mode, the case 11 is tilted at an angle of about 20 to 30 degrees with respect to the skin surface S with beauty essence applied to the skin surface, and the convex surface 122a of the vibration plate 12 is brought into contact with the skin surface S. Then, while the convex surface 122a of the vibration plate 12 is in contact with the skin surface S, the beauty device 1 is moved in the direction of the arrow. By doing so, the vibration of the vibration plate 12 is diffused over a wide range by the convex surface 122a to vibrate the skin surface S, and the introduction of ions can promote the permeation of the cosmetic ingredients into the stratum corneum.

In the case of the lift mode, with water applied to the skin surface S, the housing 11 is tilted at an angle of about 20 to 30 degrees with respect to the skin surface S as in the moist mode, and the convex surface 122a of the diaphragm 12 is applied to the skin surface S, the beauty device 1 is moved in the direction of the arrow. By doing so, the skin surface S can be cared for by the effect of vibrating the skin surface S and the microcurrent (weak current).
