[0003]

However, such a facial beauty machine has a configuration in which a weak low-frequency current is instantaneously generated and flows to the subject during treatment, so that the subject cannot handle the weak current. If he had a sensitive constitution, he could give discomfort. Further, since the practitioner who performs the treatment cannot directly check the low-frequency current, it has been difficult to determine whether or not the low-frequency current is supplied stably at the set amount of current. Therefore, the problem to be solved by the present invention is a facial beauty device having an ionic function.
An object of the present invention is to control the energization state of the low-frequency current and to easily understand the energization state of the low-frequency current.

Contacting the subject, two terminals for flowing the low-frequency current generated by the low-frequency current generation circuit to the subject, and detecting means for detecting a low-frequency current value flowing between the terminals, And a power-on state display means for displaying increase / decrease of the low frequency in multiple stages based on the detection result of the detection means.

The beautifying machine thus configured can detect the low-frequency current flowing to the subject via the two terminals during the treatment by the detecting means. Furthermore, the detection result detected by the detection means can be displayed in multiple stages as a ratio with respect to the set value, so that the practitioner can easily visually confirm the low frequency current flowing to the subject. Can be.

According to a second aspect of the present invention, a low-frequency current generating circuit for generating a low-frequency current, a control unit for controlling the low-frequency current, and a low-frequency current generating circuit,

[0007] In the beautifying machine configured as described above, the low-frequency current flowing from the two terminals to the subject is gradually increased by the conduction state control means, and is increased to the current value set by the setting means after a predetermined time. Therefore, it is possible to prevent the low-frequency current from flowing to the subject instantaneously.

Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram of the facial beauty device of the present embodiment, and FIG. 2 is a partially enlarged view of an operation unit of the facial beauty device. The facial treatment machine 1 has an ionic function for facilitating the muscle movement of the subject by passing a weak low-frequency current to the subject, and includes a face terminal 2 for lightly pressing the face of the subject. A clip terminal 3 sandwiched between wrists of the subject, and a main body 4 connected to each of the face terminal 2 and the clip terminal 3 by an energizing cord.

Further, the main body 4 includes a polarity switching relay 5 for switching the polarity of a low-frequency current flowing between the face terminal 2 and the clip terminal 3 via the patient, and an output value of the low-frequency current. A feedback unit 6 for keeping the frequency constant, and a low-frequency current generating circuit 7 for supplying a low-frequency current to the feedback unit 6
(Ionic current generation circuit), a control unit 8 for controlling the low-frequency current, and a contact determination unit for determining whether or not the face terminal 2 and the clip terminal 3 are correctly in contact with the subject. 9. Also, the main body 4
Is provided with an operation unit 10 for a practitioner to operate the facial beauty machine 1.

Next, each component of the main body 4 will be described. The feedback unit 6 is a feedback circuit 1 for feeding back the low-frequency current by an operational amplifier 11 for stabilizing the current value of the low-frequency current flowing between the face terminal 2 and the clip terminal 3.
2, an output switching relay 13 for switching ON / OFF of the feedback circuit 12, and a fuse 14 for preventing a current of a predetermined amount or more from flowing between the clip terminal 2 and the face terminal 3. I have. Note that the output switching relay 13 is turned off when the power of the beautifying machine 1 is turned on, and the potential of the clip terminal 2 and the face terminal 3 is grounded via the resistor 15 provided on the OFF side of the output switching relay 13. Is done.

Next, the low-frequency current generating circuit 7 comprises an integrating circuit for generating a low-frequency current consisting of a triangular wave having a frequency of 500 Hz and an effective value of the current of 0.3 to 0.5 mA. The low-frequency current generating circuit 7 is provided with an energization state control means for gradually increasing the low-frequency current in order to prevent the low-frequency current of the magnitude set by the practitioner from flowing to the subject instantaneously. It has a phase-in function. Here, the phase-in function performs PID control, and gradually increases the current value of the low-frequency current to be equal to the set value 0.1 to several seconds after the start of energization.

The contact judging section 9 introduces the conduction current shunted from the feedback circuit 12 to the operational amplifier 16, and outputs the output from the operational amplifier 16 and the specified value determined by the specified value generating section 17 including a dividing resistor and the like. The comparison is performed using the comparator 18. The comparator 18 is connected to the operational amplifier 16
Is smaller than the specified value, the comparator 18 outputs a high-voltage signal to the control unit 8. If the output of the operational amplifier 16 is larger than the specified value, the comparator 18 outputs a low-voltage signal to the control unit 8. When the control unit 8 receives the low voltage signal, the control unit 8 sets the clip terminal 2 and the face terminal 3
Is not in contact with the subject correctly, and the generation of the low-frequency current is stopped.

Here, between the positive side of the operational amplifier 16 and the ground, there is provided a resistor 1 serving as detecting means described in the claims.
A voltage value obtained at both ends of the resistor 19 is supplied to the control unit 8 to convert the voltage value into a current value. , The energization state display means 20 for which the comparison result will be described later.
Is displayed.

Further, the operation unit 10 has an operation panel 21 as shown in FIG.
A start / stop switch 22 for the practitioner to operate or stop the ionic function, a polarity switch 23 for changing the polarity of the low-frequency current, and setting means for the practitioner to set the current value of the low-frequency current And a display unit 25 for displaying the current value set by the current value setting switch 24. The current value setting switch 24 is composed of two switches (+) and (-), and the set value can be easily increased or decreased by operating these two keys. The switching of the polarity of the low-frequency current is used to promote the introduction of the lotion into the skin, and is used as needed.

Further, a display section 25 schematically shows a 7-segment LED (light emitting diode) 26 for displaying a current value set by a practitioner, and a current value actually flowing between the face terminal 2 and the clip terminal 3. And an energization state display means 20 for displaying the current state in multiple stages. In FIG. 2, the energization state display means 20 is constituted by three asterisk marks arranged in a horizontal direction. When none of the asterisk marks is lit, the face terminal 2 and the clip terminal 3 are in an insulated state. Means that On the other hand, when all three asterisks are lit, it indicates that a low-frequency current having a magnitude equal to the current value set by the practitioner is flowing between the face terminal 2 and the clip terminal 3. When two asterisks are lit, the face terminal 2 and the clip terminal 3
Is about 2/3 of the set value.

Next, a procedure for performing a treatment using such a facial care machine 1 will be described with reference to FIGS. First, the practitioner operates the current setting switch 24 while checking the display of the 7-segment LED 26 of the display unit 25 of the operation panel 21 shown in FIG. Set the current value of the current. Further, when the start / stop switch 22 is pressed after pressing the polarity switch 23, information on whether or not to switch the set current value and the polarity of the low-frequency current is transmitted to the control unit 8 shown in FIG. You.

The control unit 8 having received the information switches the output switching relay 13 of the feedback unit 6 to ON before issuing the low frequency current output command, as shown in step S1 of the flowchart shown in FIG. Output a very small current. Next, proceeding to step S2, the contact determination unit 9 determines contact between the face terminal 2 and the clip terminal 3 and the subject. If the current supplied to the contact determination unit 9 has not reached the predetermined value, the control unit 8 determines that the face terminal 2 or the clip terminal 3 is not in contact with the subject, and proceeds to step S3. As shown in (2), the output of the low-frequency current is stopped. In this case, the process returns to step S1 and repeats steps S1 to S3 until both the face terminal 2 and the clip terminal 3 correctly contact the subject.

On the other hand, if it is determined in step S2 that both the face terminal 2 and the clip terminal 3 are in contact with the subject, as a result of the contact determination by the contact determination section 9,
Proceeding to step S4, the control unit 8 sends a low frequency current output command to the low frequency current generation circuit 7 via the D / A converter 26. Then, the low-frequency current generating circuit 7 receiving the output command generates a low-frequency current. Further, in step S4, if the low frequency current value has reached the set value (YES), the process returns to step S2, and if the low frequency current value has not reached the set value (NO), the process proceeds to step S5.
The low frequency current value is gradually increased by the phase-in function.

At the start of the low-frequency current supply, the low-frequency current does not flow, so that the power supply state display means 20 of the operation panel 21 is turned off. However, in steps S4 and S5, the low-frequency current is supplied by the phase-in function. When the current value of the current gradually increases, the conduction state display means 20
Lights the asterisk mark in three steps. The practitioner visually confirms the energized state display means 20 and, when all three asterisks are lit, starts the practitioner on the subject. In addition, when the asterisk mark is turned off during the treatment, the practitioner may have poor contact between the face terminal 2 or the clip terminal 3 and the subject, or may have a problem with the main body 4 of the facial beauty machine 1. In addition, it is possible to easily visually confirm that a low-frequency current is not appropriately flowing to the subject. Therefore, the practitioner can immediately take predetermined measures.

While a low-frequency current is flowing between the face terminal 2 and the clip terminal 3, step S is always performed.
If the face terminal 2 or the clip terminal 3 is separated from the subject, the process proceeds to step S3 and the control unit 8 immediately stops outputting the low-frequency current.

Here, when the face terminal 2 is temporarily separated from the subject and the face terminal 2 is brought into contact with the subject again in order to change the treatment site, the face terminal 2 must be separated from the subject. Then, the contact determination unit 9 outputs a high-potential signal to the control unit 8. That is, in the flowchart of FIG. 3, since the process proceeds from step S2 to step S3, the control unit 8 stops outputting the low-frequency current. Then, when the face terminal 2 comes into contact with the subject again, the contact determination unit 9 outputs a low-potential signal to the control unit 8 and proceeds to step S4 from step S2 in the flowchart of FIG. 8 gradually increases the low frequency current. Since the low-frequency current does not flow between the time when the face terminal 2 is separated from the subject and the time when the face terminal 2 comes into contact again, the conduction state display means 20 is not turned on.

The present invention is not limited to the embodiment but can be widely applied. For example, as the energization state control means, the resistance at the subsequent stage of the comparator 11 of the feedback unit 6 in FIG. It can also be configured to control. Specifically, in step S1 of FIG. 3, the face terminal 2 and the clip terminal 3 are set by maximizing the resistance value of the variable resistor.
During this time, a small current is supplied, and in step S5, the output of the low-frequency current can be gradually increased by gradually decreasing the resistance value of the variable resistor. Further, the display of the energization state display means 20 is not limited to three stages, and may be an arbitrary stage display or a continuous display. Furthermore, the display method of the energization state display means 20 may be any method for visually confirming the energization state by the practitioner, such as using a color change, displaying an actual current value, or displaying a percentage with respect to an installation value. Means can be used.
