Description

The present invention relates to a cosmetic ultrasonic probe that transmits ultrasonic vibrations applied from an ultrasonic transducer to the skin of the face or body to obtain a cosmetic effect on the skin by ultrasonic waves. The present invention relates to the shape of the outer surface of the distal end portion, that is, the head portion of the cosmetic ultrasonic probe in contact therewith.

Conventionally, it has a tubular probe head part with a top and a gripping body that supports the probe head part, and the outer surface of the probe head part is in contact with the skin, and the inner surface of the probe head part (opposite to the outer surface) There is known a cosmetic ultrasonic probe in which the probe head portion is ultrasonically vibrated by an ultrasonic vibrator attached to the side (Patent Document 1).

JP 2006-181292 A

In the conventional cosmetic ultrasonic probe as described above, the outer surface of the probe head portion is generally circular, the ultrasonic transducer on the inner surface facing this is shaped like a disk, and both the outer surface and the ultrasonic transducer are centered. The point is configured to be orthogonal to the central axis. For this reason, the ultrasonic vibration on the outer surface, that is, the surface in contact with the skin, becomes a vibration mode in which the amplitude is larger toward the center and the amplitude is smaller toward the outer extension. Reflecting this, when the outer surface is brought into contact with the skin, vibration energy that contributes to the beauty effect tends to be concentrated on a narrow range of skin that is in contact with the vicinity of the central portion. And even if the supply power to the ultrasonic transducer is increased in order to expand this narrow range, it does not contribute so much to the expansion of the range, only the vibration energy in the vicinity of the central part is increased, and the result Specifically, the skin in the above-mentioned narrow area only became unbearably hot.

The present invention has been made in view of the above circumstances, and does not give vibration energy intensively to the skin in contact with the vicinity of the center of the outer surface of the head portion, but a wider range of the upper surface of the head portion. It is an object of the present invention to provide a cosmetic ultrasonic probe capable of giving sufficient vibration energy to the skin in contact with the skin.

In the first aspect of the invention, the cosmetic ultrasonic probe is configured as follows. That is, the outer surface of the head portion is a concave spherical surface whose outer edge is a circle, and an ultrasonic transducer is attached to the inner surface of the head portion.

According to the second aspect of the present invention, the cosmetic ultrasonic probe is configured as follows. That is, the outer surface of the head part is a concave spherical surface whose outer edge is a circle, the inner surface of the head part is a plane orthogonal to the straight line passing through the center of the spherical surface and the center of the circle, and the inner surface of the head part is A disc-shaped ultrasonic transducer was attached so that the center thereof was a point on the straight line.

In the invention of claim 3, the cosmetic ultrasonic probe is configured as follows. That is, the outer surface of the head part is a concave spherical surface whose outer edge is a circle, and the inner surface of the head part is orthogonal to the straight line passing through the center of the spherical surface and the center of the circle at the center and has a smaller radius than the circle. At the position of N points that equally divide the circumference of the second circle into N (where N is an integer greater than 2), a sticking circular plane in which the perpendicular at the center passes through the center of the spherical surface is formed. Each of the N sticking circular planes on the inner surface of the head portion is configured such that a disk-shaped ultrasonic transducer is attached so that the perpendicular passes through the center thereof.

As described in detail above, according to the cosmetic ultrasonic probe according to the present invention, the outer surface of the head portion is formed into a concave spherical surface. In the vicinity, the gap between the skin and the skin is slightly larger than in other parts, so that ultrasonic vibration energy is not concentrated on the skin in the vicinity of the center, but a relatively wide range. Uniform ultrasonic vibration energy is given to the skin.
In the cosmetic ultrasonic probe according to the second aspect of the invention, a further unique effect is that the above effect can be achieved with a very simple configuration.
In the cosmetic ultrasonic probe according to the third aspect of the invention, as a further specific effect, the head outer surface can be made relatively wide, and high emission points of ultrasonic vibration energy can be distributed and disposed at a plurality of locations on the outer surface. A relatively uniform ultrasonic vibration energy can be given to a wide range of skin in contact.

It is a figure which shows the external appearance of the ultrasonic probe for beauty which concerns on 2nd Embodiment of this invention device. It is a figure which shows the structure of the head part in the ultrasonic probe for beauty which shows an external appearance in FIG.

Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view of a head portion (substantially in the shape of a top tube) of a cosmetic ultrasonic probe according to the first embodiment along a plane defined by its axis and an arbitrary diameter. It is sectional drawing when doing. That is, the outer surface 2 of the head portion 1 is a concave spherical surface whose outer edge is a circle, and the inner surface 3 of the head portion is a plane orthogonal to the straight line passing through the center of the spherical surface and the center of the circle. 3, the disk-shaped ultrasonic transducer 4 is attached so that the center thereof is a point on the straight line. Such a configuration can be formed very simply because the outer surface of the conventional head portion is merely a concave spherical surface.

FIG. 2 shows the appearance of the cosmetic ultrasound probe according to the second embodiment.
The illustration of the cord connected to the main body device that sends out the ultrasonic output is omitted. In the lower part of the figure, there is a head part case 6 containing a head part 1 whose outer surface 2 is a concave spherical surface, and a grip part 5 is formed on the upper part.
FIG. 3 is a cross-sectional view taken along line AA shown in FIG. 2, omitting the internal mechanism and showing the arrangement relationship between the head unit 1 and the ultrasonic transducer 4. That is, the outer surface 2 of the head part is a concave spherical surface whose outer edge is a circle, and the inner surface 3 of the head part 3 is perpendicular to the center of the spherical surface and a straight line passing through the center of the circle and has a radius larger than that of the circle. At the positions of four points that divide the circumference of the small second circle into four equal parts, sticking circular planes 30 whose perpendiculars pass through the center of the spherical surface are formed. Each of the pasting circular planes 30 is configured such that a disc-shaped ultrasonic transducer 4 is pasted so that the perpendicular passes through the center thereof. The head outer surface 2 can be made relatively wide and high emission points of ultrasonic vibration energy can be formed at four locations on the outer surface 2, and the ultrasonic vibration energy from these four locations is added, resulting in a wide range of skin contacted. A relatively uniform ultrasonic vibration energy can be provided.

In addition, the range of this invention is not limited to the said embodiment, A various deformation | transformation application is possible.

The present invention is highly likely to be used in the industry related to the production of cosmetic ultrasonic probes.
