Abstract

PROBLEM TO BE SOLVED: To prevent side effects on an organism such as cytoclasis, etc., when a stop signal for an ultrasonic head is outputted from a sensor, by reducing or stopping ultrasonic stimulation irradiated from the ultrasonic head, based on the output. SOLUTION: When sliding of an ultrasonic head on an organism is stopped and the dislocation of the ultrasonic head is stopped, the stop condition is detected by a stop detection sensor 3. That is, since the output by the stop detection sensor 3 becomes constant when the sliding force of the ultrasonic head on an organism is eliminated, if the constant condition is continued for 3-10 seconds, the sensor judges the ultrasonic head stopping the sliding on the organism and giving ultrasonic vibration at a same position and stops the actuation of an ultrasonic vibration circuit 12 by opening a DC power source switching circuit 12 by a control signal form a control circuit 14. Thereby, generation of side effects such as cytoclasis in an organism can be prevented.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a beauty / slimming device using ultrasonic waves, and is equipped with a safety mechanism capable of enhancing safety to the human body particularly when the beauty / slimming device is used. It is about beauty and slimming equipment.

[0002]

2. Description of the Related Art As a means for removing wrinkles and sagging of the skin and eliminating obesity of the body, it has been conventionally known that ultrasonic stimulation is applied to the skin and the body to promote metabolism of the skin and fat. Has been.

According to the promotion of the metabolism of skin and fat, the skin is kept taut, or the activity of heat production of the living body is increased to convert a part of fat accumulated in the body into heat for consumption. By doing so, the beauty effect is enhanced.

As means for applying ultrasonic stimulation to the skin and the body, a fixing method for fixing and applying a head having a built-in ultrasonic transducer at a desired position on the skin, body surface, etc. There is a moving method that moves along the body surface while rubbing it, but the above fixing method causes a sharp temperature rise in a small area on the head contact surface, and it is difficult to control, so it is mostly used. It has not been. Further, since this fixing method is used only in a very small intensity (ultrasonic wave output) range of 0.1 to 1 W / cm ² , its output is weak and its effect is small, and therefore it is not usually used.

On the other hand, the moving method is characterized in that the wave having an uneven output distribution is made uniform by moving the head while contacting the skin and the surface of the body. Also, the range of movement is suitable to be slightly larger than the surface of the head to twice as large, and its stroke is relatively short, about 5 mm.
The stroke is about 10 cm, and each stroke overlaps the next stroke so that the ultrasonic irradiation is uniform and the head moves very slowly at a right angle to the stroke direction. By the way, since the ultrasonic output intensity used in this transfer method is 1 to 4 W / cm ² and can be employed at a considerably high intensity as compared with the fixed type, high cosmetic and slimming effects can be expected. .

Therefore, cosmetics using ultrasonic energy
For slimming, it is suitable to adopt a moving method of moving the head while rubbing the head against a living body such as skin or body surface, and conventionally, a beauty / slimming device adopting the moving method has been known.

[0007]

However, in such a beauty / slimming machine adopting the moving method, it is necessary to constantly rub the head against the living body such as the skin or the body surface. In other words, the effect of ultrasonic stimulation on the living body is the strength and time of the stimulation site. When the product exceeds a certain amount of stimulation, cells are destroyed or burns occur. Therefore, if the stimulation strength is appropriate, the stimulation time will be shortened and safety will be ensured by constantly changing the stimulation site.

Therefore, it is an essential requirement that the head be moved with respect to the living body. In the unlikely event that the head stops moving and is exposed to ultrasonic waves at the same location for a long period of time, for example, 3 to 10 minutes, the stimulus is strong for the living body, causing cell destruction and deep burns due to frictional heat due to intercellular friction. Occurrence becomes a problem.

Therefore, in order to prevent these problems, the skin surface contact position of the ultrasonic head must be constantly moved, and it is dangerous for an ultrasonic beauty / slimming device to be used by anyone who is not familiar with it. there were.

The present invention has been made paying attention to such a situation. When the movement of the ultrasonic head (vibrator cup) containing the ultrasonic transducer to the living body is stopped, the living body from the ultrasonic head is stopped. For the purpose of providing a beauty / slimming device for ultrasonic application, which can prevent the occurrence of side effects such as cell destruction in the living body and deep burn by reducing or interrupting ultrasonic irradiation to the body. There is.

[0011]

In order to achieve the above object, the present invention provides a beauty / slimming device for ultrasonic application, which applies ultrasonic stimulus emitted from an ultrasonic head having an ultrasonic transducer to a living body. In, when the contact movement of the ultrasonic head on the living body surface is stopped, when a sensor for detecting the stop and a head stop signal are output from the sensor, the ultrasonic head is irradiated based on this output. It features a beauty / slimming machine that uses ultrasonic waves and is equipped with a control circuit that reduces or stops ultrasonic stimulation.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail based on an embodiment shown in the drawings.

Reference numeral 1 denotes an ultrasonic head, which is held by a hand case 2 so as to be displaceable. Between the hand case 2 and the ultrasonic head 1, the hand case is located. A stop detection sensor 3 for detecting that the displacement of the ultrasonic head 1 with respect to 2 is stopped is provided. The stop detection sensor 3 has various structures. For example, first, the ultrasonic head 1 includes an ultrasonic cup 4 having a sectional shape, a vibrator 5 attached to an inner bottom portion of the ultrasonic cup 4, and an ultrasonic wave. The ultrasonic head 1 is composed of a lid 6 attached to the upper opening edge of the sonic cup 4, and the ultrasonic head 1 is displaced at the tip of the hand case 2 via a flexible elastic body 7 such as a bellows. It is held so that it can (swing).

The stop detection sensor 3 includes a light reflecting plate 8 mounted on the upper surface of the lid body 6, a light emitting element 9A which is located close to the light reflecting plate 8 and is fixed to the hand case 2 and has a pair. The stop type detection sensor 3 detects a stop (displacement) of the ultrasonic head 1 with respect to the hand case 2 and a reflection type optical sensor 9 having a light receiving element 9B.

The light reflecting plate 8 for reflecting the beam emitted from the light emitting element 9A to the light receiving element 9B has a plurality of concentric reflecting portions 8A as shown in FIG. It is configured so that the stop (displacement) of the reflector 8 can be detected sensitively.

FIG. 4 shows another embodiment of the stop detection sensor 3. This stop detection sensor 3 uses magnetism and has a magnet 10 fixed to the lid 6.
And a magnetic sensor 10A fixed to the handcase 2 side
And the stop (displacement) of the ultrasonic head 1 is detected.

A control circuit as shown in FIG. 5 is incorporated in the handcase 2. This control circuit is a rectifier circuit 1
1. DC power supply disconnecting circuit 13 for connecting and disconnecting the DC power supply rectified by the rectifying circuit to the ultrasonic oscillator circuit 12, and the DC power supply disconnecting circuit based on the detection signal from the stop detection sensor 3. The ultrasonic wave transmission circuit 12 is connected to the vibrator 5.

The present embodiment has been described above. Next, its operation will be described. When the power is turned on, the ultrasonic wave transmission circuit 12 is activated via the rectifier circuit 11 and the DC power supply interrupting circuit 13, and the vibrator 5 is activated. Since vibration occurs in this oscillator 5,
It is possible to apply ultrasonic vibration to the living body (part) for the purpose of beauty and slimming through the ultrasonic cup 4 of the ultrasonic head 1.

At the time of applying (transmitting) the ultrasonic stimulus to the living body, it is necessary to constantly move the ultrasonic head 1 in contact with the living body with respect to the surface of the living body, as described above. Therefore, when the ultrasonic head 1 is moving with respect to the living body surface, the DC power supply disconnection circuit 13 is in a circuit connection state, the ultrasonic oscillation circuit 12 is activated, and the vibrator 5 is oscillated.

When the ultrasonic head 1 is discontinued from sliding on the living body surface when applying ultrasonic waves to the living body surface, and the displacement (fine movement) of the ultrasonic head 1 is stopped, this stop state is detected as a stop. It is detected by the sensor 3. That is, when the rubbing force of the ultrasonic head 1 on the living body surface disappears, the output from the stop detection sensor 3 becomes constant. Therefore, if this constant state continues for 3 to 10 seconds, the ultrasonic head 1 will move to the living body surface. When stopped, it is determined that ultrasonic vibration is being applied to the same site, and the DC power supply disconnecting circuit 12 is opened by the control signal from the control circuit 14 to open the ultrasonic oscillating circuit 12.
Stops booting.

Therefore, when the ultrasonic head 1 is stopped with respect to the living body surface by this operation, the oscillation of the vibrator 5 is stopped and the ultrasonic wave irradiation to the living body surface is interrupted. Side effects can be prevented.

When the ultrasonic head 1 starts sliding on the living body surface, displacement (fine movement) occurs in the ultrasonic head 1 due to the rubbing resistance with the living body surface, and this displacement causes interruption of the DC power supply. The circuit 13 is closed and the oscillator 5 is re-oscillated.

Therefore, the movement of the ultrasonic head 1 on the living body surface,
For example, when rubbing (sliding) occurs, the oscillation operation of the vibrator is continued, and when the ultrasonic head 1 is stopped on the living body surface, the oscillation operation of the vibrator is interrupted.
Since it is possible to avoid applying ultrasonic stimulation to the same place on the living body surface for a long time, it is possible to effectively prevent the occurrence of side effects on the living body surface due to concentrated irradiation of ultrasonic waves.

In the above embodiment, when the movement of the ultrasonic head 1 is stopped, the vibration of the vibrator 5 is stopped (interrupted).
However, the present invention is not limited to this, and for example, when the movement of the ultrasonic head 1 is stopped, the output of ultrasonic vibration by the vibrator 5 is attenuated to prevent side effects on the living body surface. You may make it avoid.

[0025]

As described above, according to the present invention, when the movement (sliding) of the ultrasonic head on the living body surface is stopped, the ultrasonic waves radiated from the ultrasonic head onto the living body surface automatically. Since it is interrupted, the ultrasonic waves are not intensively applied to the extreme parts of the human body, and thus side effects due to ultrasonic irradiation can be prevented in advance.
