A lamp group 54 is connected.

Note that a charging connector (not shown) for charging the power source 47 is provided outside the main body 11.
Next, the operation of the facial beauty device configured as above will be explained.

The facial beauty device of this embodiment is held by the user, and the tip of the head portion 13 is applied to the skin such as the cheek, and current is applied to the skin from the first, second, and third electrodes 16, 17, and 18. It is supplied and used for beauty treatment. That is, in the facial beauty device of this embodiment, by pressing and holding the power switch 26, the control device 41 is energized, and the facial beauty device enters an operation standby state. Then, by pressing the power switch 26 for a short time, one of the aforementioned CL mode, MC mode, PI mode, RF mode, and EMS mode is selected and executed.

In each of these modes, the electric resistance of the human body is detected by the detection current flowing through the human body of the user between the second electrode 17 and the fourth electrode 24, and as a result, the electric resistance of the human body is detected. It is detected that the first, second, and third electrodes 16, 17, and 18 are applied to the cheeks of the user, and that the main body 11 is being held by the user. In other words, the state of use by the user is detected.

In the CL mode, a voltage of a level suitable for cleansing is applied between the second electrode 17 and the fourth electrode 24 with a duty ratio of 50 percent (%) and a rectangular wave high frequency current of 1 kilohertz (KHz). It is something that will be done. Therefore, with the head portion 13 of the facial beauty device in contact with the user's skin such as the cheek, a high frequency current flows through the user who is holding the facial beauty device on the skin. In this case, the high frequency current is one in which one negative pulse is output for every 19 positive pulses, and thereby cleansing can be performed to remove dirt from the skin. In this CL mode, the vibrator motor 53 operates to apply vibrations to the skin in order to make the cleansing effect more effective and provide comfort. Further, in this CL mode, ultraviolet rays having a bactericidal and sterilizing effect on the skin are irradiated from the blue lamp 33.

The MC mode is a rectangular wave high frequency current of 1 kilohertz (KHz) with a duty ratio of 50% between the second electrode 17 and the fourth electrode 24, and a voltage at a level suitable for conditioning biological cells. It is applied. In this case, the high-frequency current is one in which bipolar pulses are output alternately, and thereby the skin can be activated. In this MC mode, the yellow lamp 32 irradiates the skin with yellow light that activates living cells.

In the PI mode, a voltage with a duty ratio of 30% and a rectangular wave high frequency current of 10 kilohertz (KHz) at a level suitable for iontophoresis is applied between the second electrode 17 and the fourth electrode 24. It is something. The high-frequency current in this case is one in which pulses of negative polarity are output, which allows ions to be introduced into the skin, thereby allowing the cosmetic ingredients to penetrate into the skin. In this PI mode, the ultrasonic vibration device 52 operates to apply ultrasonic vibration to the skin in order to make the iontophoresis effect effective.

In the RF mode, a 1 megahertz (MHz) sinusoidal current is applied between the first electrode 16 and the third electrode 18, and a voltage at a level suitable for heating the skin is applied. In this case, the high-frequency current is one in which bipolar pulses are output alternately, and as a result, the high-frequency current flows between the first electrode 16 and the third electrode 18, and the Joule heat is applied to the deep part of the skin. It can be heated from

In the RF mode, the following processing is executed.
The flowcharts shown in FIGS. 10 to 12 are for executing processing in the RF mode, in which a program stored in the storage unit 43 of the control device 41 proceeds under the control of the central processing unit 42. It is. The storage unit 43 is provided with areas for data such as flags and status codes that are temporarily switched or stored.

The RF mode main routine shown in FIG. 10 is executed periodically (for example, every 1/10 second). In step 1 of this main routine (hereinafter simply referred to as S), it is determined whether or not the RF mode time of 3 minutes has elapsed, and if it has elapsed, the program is terminated. If it is determined in S1 that three minutes have not yet elapsed, the program moves to S2. In this S2, based on the detection from the acceleration sensor 48, the beauty device is in a state (Status 1) in which it is moving at an acceleration of a predetermined value or more or a constant speed of a predetermined value or more, and the temperature sensor 51 is a predetermined value or less. It is determined whether or not the temperature is being detected (status 2). If both are detected, the RF mode is executed in S3. In S2, if it is determined that at least one of status 1 and status 2 is not set, that is, if acceleration and constant speed movement are not detected, or if the detected temperature is higher than a predetermined value, the RF mode is turned off. be done.

FIG. 11 shows a regular interrupt routine executed in the main routine of FIG. 10, and shows processing operations based on detection by the acceleration sensor 48. In S11 of FIG. 11, the acceleration sensor 48 determines whether the facial beauty device has been moved with an acceleration equal to or higher than a predetermined value. If the acceleration is equal to or greater than the predetermined value, a flag "1" is set in S12. If the acceleration is less than or equal to the predetermined value, the flag becomes "0" in S13. In S14, the flags of the current routine and the flags of the previous routine are compared. If the flags of both routines are different, that is, if the facial beauty device is accelerated or decelerated, the counter 46 is reset in S15 and the program ends.

In S14, if it is determined that the flags of both routines are the same, that is, if the movement of the facial beauty device has been further accelerated or decelerated in the current routine, if the facial beauty device is moving at a constant speed, or if the facial beauty device is moving at a constant speed, If the movement is stopped, "1" is added to the count value of the counter 46 in S16. Next, in S17, it is determined whether the count value of the counter 46 has reached "10", and if it has not reached "10", the program ends.

If it is determined in S17 that the count value has not yet reached "10", it is determined in S18 whether or not the flag "1" was set in the previous routine. If it is set, that is, if acceleration/deceleration was executed or constant speed movement in the previous routine, status 1 is set in S19 as it is determined that the acceleration/deceleration is greater than a predetermined value or the constant speed movement is being performed. Set to "1". If acceleration has stopped in the previous routine and the vehicle is at rest, status 1 is set to "0" in S20. In this way, when the facial beauty device is accelerating or decelerating beyond a predetermined value or moving at a constant speed, the status 1 becomes "1" and is used for the determination in S2 of the main routine in FIG.

FIG. 12 shows a routine for temperature detection by the temperature sensor 51, which is executed by a regular interrupt in the main routine of FIG.
In S21, it is determined whether the temperature detected by the temperature sensor 51 is a certain temperature higher (for example, 0.2 degrees Celsius) than the set value set in the RF mode, and if it is higher, in S22, the status 2 is changed to "0'' and the output of the RF mode is turned off, and then the program is terminated. If it is determined in S21 that the temperature detected by the temperature sensor 51 is not a certain temperature higher than the set value, in S23 the temperature detected by the temperature sensor 51 is lower than the set value by a certain temperature (for example, 0.2 degrees Celsius). It is determined whether or not the value is high, and if it is high, the program is terminated. If the detected temperature is a certain temperature lower than the set value, the RF status 2 is set to "1" in S24, and the RF mode output is maintained. This status 2 is used for determination in step S2 in the main routine of FIG.

In the EMS mode, the first electrode 16 and the second electrode 17 (α), the first electrode 16 and the third electrode 18 (β), A bipolar rectangular high frequency current voltage shown in the upper part of FIG. 9 is applied to the second electrode 17 and the third electrode 18 (γ) at 1.2 second intervals. This high frequency current has a duty ratio of 50%, and 5 kilohertz (KHz) is sequentially applied in cycles. By applying this high-frequency current, muscles such as the facial muscles of the user's cheeks that are in contact with the head portion 13 are trained.

The voltage application duration of the high frequency current to each electrode pair α, β, γ is 1 second, and a voltage application pause period ε of 0.2 seconds is provided between the voltage application duration δ. Then, the first electrode 16 and the second electrode 17 (electrode pair α), the first electrode 16 and the third electrode 18 (electrode pair β), and the second electrode 17 and the third electrode 18 (electrode pair γ) are A first cycle is performed in which a voltage of current is applied. In the second cycle, in which the high-frequency current voltage is similarly applied, the first electrode 16 and the third electrode 18 (electrode pair β), the first electrode 16 and the second electrode 17 (electrode pair α), the second electrode 17 and the third electrode The three electrodes 18 (electrode pair γ) are executed in this order, and the first and second cycles are continuously executed alternately. In the first cycle and the second cycle, a high frequency current of 5 KHz is intermittently applied 8 times and 20 times, respectively. In addition, as shown in the lower part of FIG. 9, the voltage of the pulse current for human body detection, which will be described later in FIG. is applied. The voltage of this detection current may be applied at any timing within or between the intermittent application times of the high frequency current in each cycle.

Moreover, in the EMS mode, at the beginning, the high frequency current is initially at a low voltage and is gradually transferred to a high voltage for muscle training. Therefore, the user can avoid discomfort caused by sudden high voltage and can use the device comfortably.

The high-frequency current in this EMS mode trains the facial muscles of the user's cheeks and other muscles. By intervening the voltage application pause period ε, switching the frequency of the high-frequency current, and switching the electrode pairs α, β, and γ to which the high-frequency voltage is applied, the user can feel the muscle training effect in the EMS mode. . Further, in this EMS mode, red light having the effect of activating living cells is irradiated from the red lamp 31.

FIG. 13 shows a routine for skin detection in each mode.
That is, in S31, it is determined whether the current mode is the EMS mode. If the mode is other than the EMS mode, an operating current for executing the mode other than the EMS mode is supplied in S32, and the mode other than the EMS mode is executed. Then, in S33, it is detected whether or not electricity is flowing between the second electrode 17 and the fourth electrode 24. If the user holds the facial beauty device by grasping the fourth electrode 24 of the main body 11 and energization through the human body is detected, an operation in a mode other than the EMS mode is executed in S34. If it is not detected, the operation of modes other than the EMS mode is disabled in S35, and that mode is not executed.

If it is determined in S31 that the current mode is the EMS mode, it is determined in S36 whether or not one pulse current (upper part of FIG. 9) for executing the EMS mode is being output. Then, when the pulse current of the EMS current is not output, in S37, the voltage of the pulse current for skin detection is applied between the second electrode 17 and the fourth electrode 24 (lower part of FIG. 9). Next, when a current passing through the human body between the second electrode 17 and the fourth electrode 24 is detected in S33, the EMS mode is activated in S34. Furthermore, if no detection is made, the operation is stopped in S35.

As described above, in the case of a mode other than the EMS mode, it is recognized that the facial beauty device is being used while being held by the user because the high frequency current for executing that mode flows through the human body. . In addition, in the case of the EMS mode, a current other than the high-frequency current for executing the EMS mode flows through the human body, so that it is recognized that the facial beauty device is being used while being held by the user. .

Therefore, this embodiment exhibits the following effects.
(1) In each beauty mode including the EMS mode, a human body is detected in a usable state in which the facial beauty device is held by a user and the head portion 13 is placed against the human body. Based on this detection of the human body, each mode is executed to supply high frequency current, vibration, and ultrasonic vibration to the skin, and at the same time, one of the lamps 31, 32, and 33 of the head section 13 irradiates the skin. be done. Therefore, even if lotion, lotion, etc. remain between the first, second, and third electrodes 16, 17, and 18, the facial beauty device will not be operated unless a human body is detected. Therefore, when the facial beauty device is not in use, the facial beauty device is not activated, and wasteful consumption of power from the power source 47 can be avoided.

(2) In the RF mode, when the head part 13 of the facial beauty device is moving on the skin of the user and when the temperature of the skin is below a predetermined temperature, supply of high frequency current in the RF mode is executed between the electrodes. . Conversely, when the head part 13 of the facial beauty device is stopped on the user's skin, and when the skin is heated to a predetermined temperature or higher and the temperature is detected, the high-frequency current is not supplied. will be stopped. Therefore, the user is prevented from feeling uncomfortable high temperatures when using the facial beauty device.

(3) In the RF mode, when it is detected that the facial beauty device has stopped moving, the heating operation for the skin is stopped. Therefore, if the operation of the temperature sensor 51 becomes unstable or malfunctions, it is sufficient to stop the movement of the facial beauty device. Therefore, discomfort during use such as overheating caused by a malfunction of the temperature sensor 51 can be avoided.

(4) A projecting portion 14 is provided on the main body 11 of the facial beauty device. A power switch 26, a level switch 27, a mode display lamp 29, and a level display lamp 30 are arranged on the projecting portion 14 side. Therefore, a space for arranging the switches and lamps can be secured without difficulty, and the switches can be easily operated with the thumb or the like, compared to a case where the switches are arranged in the center of the main body 11. Furthermore, the presence of the protruding portion 14 makes the entire main body 11 a non-symmetrical shape, which can avoid being mistaken for other electrical equipment such as a symmetrical electric razor. Further, by utilizing the internal space of the overhanging portion 14, functional components such as an electric circuit board can be easily installed inside, and the facial beauty device can be highly functional.
