Abstract

PROBLEM TO BE SOLVED: To provide an ultrasonic vibration element used in cosmetic equipments, curing instruments, medicine effect promoters, or the like using ultrasonic waves. SOLUTION: This ultrasonic vibration element is formed into a planer body 1 as a vibration member consisting of functional ceramics. To the planer body 1, an ultrasonic vibration transducer 2 is stuck, and the planer body 1 is stuck to the lower end of a cover 3, and to the cover 3, a clamping part 4 is fixed, and through this clamping part 4, lead wires 5 are connected to an outer oscillator. When an output signal is inputted from the outer oscillator to the ultrasonic vibration transducer 2 for the ultrasonic vibration element, and the vibrating plate 1 of functional ceramics is contacted with the human body, ultrasonic waves from the ultrasonic vibration transducer 2 can stimulate the human body through the planer body 1 as the vibration plate member.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ultrasonic vibrating element used in a cosmetic device using ultrasonic waves, a therapeutic device, a drug effect promoting device and the like.

[0002]

2. Description of the Related Art Conventionally, ultrasonic vibrating elements used in cosmetic devices and therapeutic devices using ultrasonic waves, as well as in medical effect promoting devices, include:
It is common to use a metal such as stainless steel for the ultrasonic radiation surface.

[0003]

In the case where the surface of the ultrasonic wave coming into contact with the human body is a stainless steel plate, the output applied to the ultrasonic vibrator from the oscillator may leak to the human body. Therefore, it is necessary to take an insulating means such as connecting an ultrasonic vibrator to the output side of the oscillator via an insulating transformer, so that the configuration of the device becomes large, the configuration is complicated, and it becomes expensive. There was a problem.

[0004]

According to the present invention, an ultrasonic vibrator is adhered to a vibrating member made of functional ceramics, and a cover is adhered to the functional ceramics. Alternatively, the insulating vibration member may have a box shape in which a part is opened.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the present invention, it is not necessary to insulate an oscillator supplying an oscillation output with an insulating transformer or the like by bonding an ultrasonic vibrator to a vibrating member made of functional ceramics. Ceramics are easy to cut into the desired shape because they are free-cutting, and the acoustic impedance of functional ceramics (about 14.5)
Has good matching with the acoustic impedance of the human body (about 1.5).

[0006]

FIG. 1 is a side view of an ultrasonic vibrating element according to an embodiment of the present invention. The vibrating member made of a functional ceramic is formed on a plate-like body 1, and an ultrasonic vibrator 2 is attached to the plate-like body 1. Are adhered, and the plate-like body 1 is adhered to the lower end of the cover 3,
A grip 4 is fixed to the cover 3, and a lead wire 5 is connected to an external oscillator (not shown) through the grip 4.

When an output signal is input from an external oscillator to the ultrasonic vibrator 2 of the ultrasonic vibrating element of the present embodiment having the above-described configuration, and the vibrating plate 1 made of functional ceramic is brought into contact with a human body, the ultrasonic vibration Ultrasonic waves from the child 2 can stimulate the human body through the diaphragm 1 with ultrasonic waves.

Since the vibrating member made of the functional ceramic has a free-cutting property, the vibrating member can be cut into any shape with respect to the shape of the cover 3. The insulating property of the functional ceramic used as the plate 1 is 17.9 KV / mm to 40 KV / mm.
Therefore, there is an advantage that the insulating property is good for the human body. Further, the acoustic impedance PC of the functional ceramic is about 14.5, while the acoustic impedance of stainless steel is 45.7, Is good for the acoustic impedance (PC is about 1.5).

FIG. 2 is a side sectional view of an ultrasonic vibrating element according to another embodiment of the present invention, wherein 2 is an ultrasonic vibrator, 3 is a cover,
Reference numeral 4 denotes a gripping portion, and 5 denotes a lead wire. These components are the same as those in the above-described embodiment, and thus description thereof will be omitted. The ultrasonic vibrator 2 includes a box-shaped body 6.
Is glued to the inside bottom surface.

[0010] Also in the present embodiment thus constructed, since the functional ceramic has a free-cutting property, the box-shaped body 6
The bottom surface of the box-shaped body 6 is projected from the cover 3 to form a groove 6a on the side surface of the box-shaped body 6, and the lower end of the cover 3 can be inserted into and bonded to the groove 6a. Even if the bottom surface of the box-shaped body 6 is brought into contact with the body, it can be insulated from the human body.

In the description of the above embodiment, the vibrating member made of the functional ceramic is constituted by a plate-like body and a box-like body.
Since it has a free-cutting property, it can be easily formed into another shape, and the cover 3 can be formed into a shape other than the above embodiment.

[0012]

As described above, in the ultrasonic vibration element of the present invention, since the functional ceramic is used as the vibrating member, the functional ceramic has a free-cutting property. It is easy to make it into a shape or other shape, and functional ceramics have excellent electrical insulation, so they can be insulated from the human body. Since the impedance is closer to the acoustic impedance of the human body than that of stainless steel or other metals, there is an advantage that the matching with the human body is good.
