Detailed Description

(embodiment mode)

Hereinafter, embodiments embodying the present invention will be described based on the drawings. In the present embodiment, the beauty apparatus is embodied as a beauty device.

The outer case 12 of the main body 11 of the beauty instrument shown in fig. 1 functions as a handle to be held by a user of the beauty instrument. Various components such as a circuit board and a power supply are mounted inside the case housing 12. As shown in fig. 4, a protrusion 14 is formed at one side portion of the body 11 at a position other than the head 13 of the beauty instrument. Therefore, the beauty instrument of the present embodiment is formed in a laterally asymmetrical shape.

As shown in fig. 2 and 3, a low cylindrical projecting portion 15 is formed on the head portion 13 of the main body 11, and a first electrode 16, a second electrode 17, and a third electrode 18 that are in contact with the skin of the user are disposed so as to be exposed on the front surface of the projecting portion 15. The first electrode 16, the second electrode 17, and the third electrode 18 constitute cosmetic electrodes. The first electrode 16 is circular and disposed at the center of the projection 15. The second electrode 17 and the third electrode 18 are each in a semicircular arc shape and are disposed on the outer peripheral side of the protruding portion 15 around the first electrode 16. A space is provided between the first electrode 16, the second electrode 17 and the third electrode 18, in which space an electrically insulating material 19 is provided. Therefore, the first electrode 16, the second electrode 17, and the third electrode 18 are electrically insulated from each other. Then, a voltage based on a high-frequency pulse current or a sine wave current for beauty treatment is applied between the first electrode 16 and the second electrode 17, between the first electrode 16 and the third electrode 18, and between the second electrode 17 and the third electrode 18.

As shown in fig. 1, 2, and 6, the head 13 has a plurality of flat portions 21 having a substantially triangular shape formed around the protruding portion 15, and a permanent magnet 22 is provided on the flat portions 21 inside the case 12. A flat ring-shaped holding member 23 made of a magnetic material such as iron is fitted to the protrusion 15 and fixed to the flat surface 21 in a state of being attracted to the permanent magnet 22 of the flat surface 21. A cloth (not shown) such as cotton yarn covered on the front surface side of the protruding portion 15 is held by the holding member 23.

As shown in fig. 4, a power switch 26 and a level switch 27 are disposed on the back surface of the main body 11 at positions close to the extension portion 14. By long-pressing the power switch 26 (for about 1.5 seconds), the currents supplied to the first electrode 16, the second electrode 17, and the third electrode 18 are turned on and off. The power switch 26 has a function of switching the operation mode of the beauty appliance by being pressed for a short time. The operation modes of the beauty apparatus are a Cleaning (CL) mode, a micro-current (MC) mode, an iontophoresis (PI) mode, a high-frequency heating (RF) mode, and an Electric Muscle Stimulation (EMS) mode, which will be described later. The voltage level of the high-frequency current or the sine wave current in each mode is arbitrarily switched according to a user's request or the like each time the level switch 27 is pressed.

As shown in fig. 5, a power supply lamp 28 that displays the on state of the power supply by lighting is disposed at the head-side end portion on the back surface of the main body 11. As shown in fig. 4, a plurality of mode indicator lamps 29 are disposed at the end edge of the extension portion 14 on the back surface of the main body 11, and these mode indicator lamps 29 indicate the mode selected by the power switch 26. A plurality of gradation display lamps 30 are arranged on the back surface of the main body 11 at positions close to the projecting portions 14, and these gradation display lamps 30 display the output levels switched by the gradation switch 27.

The case 12 constituting the main body 11 includes: a base housing 121, and a first cover housing 122 covering the base housing 121 in the extension portion 14. The mode indication lamp 29 and the gradation indication lamp 30 of the first cover case 122 are partially transparent or translucent, and it can be determined whether or not the

lamps

29 and 30 are lit.

As shown in fig. 4, a second cover case 123 is provided at a position covering the front and back surfaces of the outer surface of the base case 121 except for the extension portion 14. The second cover case 123 has a transparent or translucent portion of the power lamp 28, and can determine whether or not the power lamp 28 is lit. The third cover case 124 is provided at a position covering the front surface of the extension portion 14. The surface of the third housing 124 is subjected to metal plating. Therefore, the surface of the third cover case 124 has conductivity. Therefore, the third casing 124 can function as an electrode. Accordingly, the third cap housing 124 will be referred to as a fourth electrode 24 as a detection electrode hereinafter.

As shown in fig. 6, twelve red lamps 31, six yellow lamps 32, and six blue lamps 33 are disposed inside the outer shell 12 on the inner side of the annular portion 191 of the transparent or translucent insulating material 19 between the first electrode 16, the second electrode 17, and the third electrode 18. These

lamps

31, 32, and 33 are formed of light emitting diodes, and are arranged at equal intervals. The red lamp 31 irradiates red light, the yellow lamp 32 irradiates yellow light, and the blue lamp 33 irradiates blue light.

A temperature sensor 51, for example, a thermistor as shown in fig. 7 for detecting the temperature of the portion between the first electrode 16, the second electrode 17, and the third electrode 18 is provided on the back surface side of the insulating material 19.

An acceleration sensor 48, an ultrasonic vibration device 52, and a vibration motor 53 shown in fig. 7 are provided inside the head portion 13 of the main body 11. The acceleration sensor 48 detects the levels of acceleration and deceleration (hereinafter, collectively referred to as acceleration) in the three-axis direction during movement of the beauty instrument. The ultrasonic vibration device 52 generates ultrasonic waves deviating from a sound range of about 1 to 5 megahertz (MHz), and the vibration motor 53 generates vibration of about 50 to 200 Hz.

Fig. 7 shows an electrical configuration of the beauty instrument of the present embodiment.

In fig. 7, the control device 41 of the beauty instrument includes: a central processing unit 42 as a control unit for controlling the operation of the entire beauty apparatus, a storage unit 43 for storing a program and temporary data, a timer 44, a detection unit 45 as a detection unit, and a counter 46. The timer 44 measures an elapsed time after the start of the operation in each mode. The detection unit 45 detects whether or not current is passed between the second electrode 17 and the fourth electrode 24. The counter 46 counts the number of flags set as described later. A power supply 47 made of a secondary battery supplies electric power to the control device 41 and various electric/electronic devices. A temperature sensor 51, a fourth electrode 24, a power switch 26, a level switch 27, and an acceleration sensor 48 are connected to an input side of the control device 41. The first electrode 16, the second electrode 17, the third electrode 18, the ultrasonic vibration device 52, the vibration motor 53, and the display lamp group 54 including the

lamps

28, 29, 30, 31, 32, and 33 are connected to the output side of the control device 41.

A charging connector (not shown) for charging the power supply 47 is provided outside the main body 11.

Next, the operation of the beauty instrument configured as described above will be described.

The beauty instrument of the present embodiment is held by a user, and the tip of the head 13 is brought into contact with the skin such as the cheek, and current is supplied from the first electrode 16, the second electrode 17, and the third electrode 18 to the skin for beauty. That is, in the beauty instrument of the present embodiment, the energization of the control device 41 is performed by the long press of the power switch 26, and the beauty instrument is in the operation standby state. Then, by a short-time pressing operation of the power switch 26, one of the CL mode, MC mode, PI mode, RF mode, and EMS mode is selected and executed.

In each of the modes, the resistance of the human body is detected by detecting the flow of current through the human body of the user between the second electrode 17 and the fourth electrode 24, and as a result, it is detected that the first electrode 16, the second electrode 17, and the third electrode 18 of the beauty instrument are in contact with the cheek or the like of the user and the main body 11 is held by the user. That is, the detection is based on the user's usage status.

In the CL mode, a voltage of a level suitable for cleaning with a rectangular wave high frequency current of a duty ratio of 50% (percent) and 1 kilohertz (KHz) is applied between the second electrode 17 and the fourth electrode 24. Therefore, in a state where the head 13 of the beauty instrument is in contact with the skin such as the cheek of the user, a high-frequency current flows to the skin through the user gripping the beauty instrument. In this case, the high-frequency current can be used to perform cleaning for removing stains from the skin by outputting one negative pulse for nineteen positive pulses. In the CL mode, the vibration motor 53 is operated to vibrate the skin in order to provide a comfortable feeling while the cleaning action is effective. In addition, in the CL mode, ultraviolet rays having a sterilizing and disinfecting action are irradiated from the blue lamp 33 to the skin.

In the MC mode, a voltage suitable for adjusting the level of living cells is applied between the second electrode 17 and the fourth electrode 24 with a rectangular wave high-frequency current having a duty ratio of 50% and 1 kilohertz (KHz). In this case, the high-frequency current alternately outputs bipolar pulses, whereby activation of the skin can be achieved. In the MC mode, yellow light having an activating effect on living cells is irradiated from the yellow lamp 32 to the skin.

In the PI mode, a voltage of a level suitable for iontophoresis, which is a rectangular wave high-frequency current having a duty ratio of 30% and 10 kilohertz (KHz), is applied between the second electrode 17 and the fourth electrode 24. In this case, the high-frequency current outputs a negative pulse, so that iontophoresis can be performed on the skin, and thus the skin can be permeated with the cosmetic component. In the PI mode, the ultrasonic vibration device 52 is operated to apply ultrasonic vibration to the skin in order to effect the iontophoresis action.

In the RF mode, a sine wave current of 1 megahertz (MHz) and a voltage of a level suitable for heating of the skin are applied between the first electrode 16 and the third electrode 18. In this case, the high-frequency current alternately outputs bipolar pulses, and thus the high-frequency current flows between the first electrode 16 and the third electrode 18, and the skin can be heated from the deep portion of the skin by joule heat.

In the RF mode, the following processing is performed.

The flowcharts shown in fig. 10 to 12 are for executing the processing in the RF mode, and the program stored in the storage unit 43 of the control device 41 is executed under the control of the central processing device 42. The storage unit 43 is provided with an area for temporarily switching or storing data such as a flag and a status code.

The main routine of the RF mode shown in fig. 10 is executed periodically (e.g., every tenth of a second). In step (hereinafter, abbreviated as S)1 in the main routine, it is determined whether or not 3 minutes, which is the RF mode time, has elapsed, and when it has elapsed, the routine is terminated. In S1, when it is judged that 3 minutes has elapsed, the routine proceeds to S2. In S2, based on the detection from the acceleration sensor 48, it is determined whether or not the beauty instrument is in a state of moving at an acceleration of a predetermined value or more or at a predetermined speed of a predetermined value or more (state 1), and whether or not the beauty instrument is in a state of detecting a temperature of a predetermined value or less by the temperature sensor 51 (state 2). If both are detected, the RF mode is executed in S3. In S2, when at least one of the state 1 and the state 2 is not set, that is, when the acceleration and the constant velocity movement are not detected or when the detected temperature is equal to or higher than a predetermined value, the RF mode is turned off.

Fig. 11 shows a timer interrupt routine executed in the main routine of fig. 10, and shows a processing operation based on detection by the acceleration sensor 48. In S11 of fig. 11, it is determined by the acceleration sensor 48 whether or not the beauty instrument is moving at an acceleration equal to or higher than a predetermined value. When the acceleration is equal to or greater than the predetermined value, a flag "1" is set in S12. When the acceleration is equal to or less than the predetermined value, the flag is "0" in S13. In S14, the flag of the current routine and the flag of the previous routine are compared. When the flags of the two programs are different, that is, when the beauty instrument is accelerated and when the beauty instrument is decelerated, the counter 46 is reset in S15, and the program is ended.

If it is determined in S14 that the flags of both programs are the same, that is, if the movement of the beauty appliance is further accelerated or decelerated in the current program, if the beauty appliance is moving at a constant speed, or if the movement of the beauty appliance is stopped, the count value of the counter 46 is incremented by "1" in S16. Next, at S17, it is determined whether or not the count value of the counter 46 has reached "10", and if not, the routine is ended.

If it is determined in S17 that the count value is before "10", it is determined in S18 whether or not a flag "1" was set in the previous routine. In the case of the setup, that is, in the case where acceleration or deceleration is performed in the previous routine and in the case of the constant speed movement, in S19, if acceleration or deceleration is performed by a predetermined value or more or the constant speed movement is performed, the state 1 is set to "1". If the acceleration is stopped and the program is stopped in the previous routine, state 1 is set to "0" in S20. In this way, when the beauty apparatus is accelerating or decelerating by a predetermined value or more or is moving at a constant speed, the state 1 is "1" and is used for determination at S2 in the main routine of fig. 10.

Fig. 12 shows a routine based on temperature detection by the temperature sensor 51, and is executed by timer interruption in the main routine of fig. 10.

In S21, it is determined whether or not the temperature detected by the temperature sensor 51 is higher than a set value set in the RF mode by a predetermined temperature (for example, 0.2 degrees celsius), and if so, state 2 is set to "0" in S22, and the routine is ended after the output of the RF mode is turned off. If it is determined in S21 that the temperature detected by the temperature sensor 51 is not higher than the set value by a predetermined temperature, it is determined in S23 whether the temperature detected by the temperature sensor 51 is lower than the set value by a predetermined temperature (for example, 0.2 degrees celsius), and if so, the routine is ended. If the detected temperature is lower than the set value by a predetermined temperature, the RF state 2 is set to "1" in S24, and the RF mode output is maintained. This state 2 is used for determination in step S2 in the main routine of fig. 10.

In the EMS mode, as shown by the electrode pairs α, β, γ in fig. 6 and 8, voltages of bipolar rectangular wave high-frequency currents shown in the upper part of fig. 9 are applied to the first electrode 16 and the second electrode 17(α), the first electrode 16 and the third electrode 18(β), and the second electrode 17 and the third electrode 18(γ) at intervals of 1.2 seconds, respectively. The high frequency current of duty ratio 50% and 5 kilohertz (KHz) is periodically applied in turn. By applying the high-frequency current, muscles such as facial muscles of the cheek of the user contacting the head 13 are exercised.

The voltage application duration of the high-frequency current to each electrode pair α, β, γ was 1 second, and a voltage application rest period ∈ of 0.2 second was provided between the voltage application durations δ. Further, the first period of applying the voltage of the high-frequency current is performed in the order of 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). The second period in which the same high-frequency current is applied to the voltage is performed in the order of the first electrode 16 and the third electrode 18 (electrode pair β), the first electrode 16 and the second electrode 17 (electrode pair α), and the second electrode 17 and the third electrode 18 (electrode pair γ), and the first period and the second period are alternately performed. In the first and second periods, high-frequency current of 5KHz was intermittently applied 8 times and 20 times, respectively. As shown in the lower part of fig. 9, at a timing when the pulse of the high-frequency current is not generated, a voltage of a pulse current for human body detection, which will be described later in fig. 13, is applied between the second electrode 17 and the fourth electrode 24. The voltage of the detection current may be applied at any timing of the intermittent application time and the timing between the intermittent application times of the high-frequency current in each cycle.

In the EMS mode, the high-frequency current is initially at a low voltage and gradually shifts to a high voltage for muscle training at the start of the EMS mode. Therefore, the user can be comfortably used without giving uncomfortable feeling due to sudden high voltage.

The muscles such as facial muscles of the cheek of the user are exercised by the high-frequency current of the EMS mode. Further, the user feels the muscle exercise effect in the EMS mode by the insertion of the voltage application rest period ∈ and the switching of the frequency of the high-frequency current, even by the switching of the electrode pair α, β, γ to which a high frequency is applied. In the EMS mode, red light having an action of activating biological cells is emitted from the red lamp 31.

Fig. 13 shows a procedure for skin detection in each mode.

That is, in S31, it is determined whether or not the current mode is the EMS mode. In the case of the mode other than the EMS mode, in S32, an operating current for executing the mode other than the EMS mode is supplied, and the mode other than the EMS mode is executed. Then, in S33, whether or not current is passed between the second electrode 17 and the fourth electrode 24 is detected. When the user holds the fourth electrode 24 of the main body 11 and holds the beauty instrument and detects the conduction through the human body, the operation in the mode other than the EMS mode is executed in S34. If not, the operation of the mode other than the EMS mode is invalidated at S35, and the mode is not executed.

If it is determined in S31 that the current mode is the EMS mode, it is determined in S36 whether one pulse current (upper part of fig. 9) for EMS mode execution is at the time of output. When the pulse current of the EMS current is not output, a voltage of the pulse current for skin detection is applied between the second electrode 17 and the fourth electrode 24 in S37 (lower part of fig. 9). Next, when the current of the human body passing through the gap between the second electrode 17 and the fourth electrode 24 is detected in S33, the EMS mode is operated in S34. If not, the operation is stopped in S35.

As described above, in the case of the mode other than the EMS mode, the high frequency current for executing the mode flows through the human body, thereby recognizing that the beauty instrument is in use being held by the user. In the EMS mode, a current different from a high-frequency current for executing the EMS mode is applied to a human body, and thus it is recognized that the beauty instrument is in use while being held by a user.

Therefore, the present embodiment exhibits the following effects.

(1) In each mode for beauty treatment represented by the EMS mode, a human body is detected in a usable state where the beauty treatment apparatus is held by a user and the head 13 is in contact with the human body. Then, based on the detection of the human body, each mode is executed to supply a high-frequency current, vibration, and ultrasonic vibration to the skin and irradiate any of the

lamps

31, 32, and 33 of the head 13. Therefore, even if the lotion, or the like remains between the first electrode 16, the second electrode 17, and the third electrode 18, the beauty apparatus is not operated unless the human body is detected. Therefore, the beauty apparatus does not operate in the non-use state of the beauty apparatus, and the power from the power supply 47 can be prevented from being consumed unnecessarily.

(2) In the RF mode, when the head 13 of the beauty instrument is moved over the skin of the user and when the skin is at a temperature equal to or lower than a predetermined temperature, the RF mode supply of the high-frequency current is performed between the electrodes. On the other hand, when the head 13 of the beauty instrument is stopped on the skin of the user and when the skin is overheated to a temperature equal to or higher than a predetermined temperature and the temperature is detected, the supply of the high-frequency current is stopped. Therefore, the user is inhibited from feeling an uncomfortable high temperature when using the beauty apparatus.

(3) In the RF mode, when the movement of the beauty instrument is detected to be stopped, the heating operation to the skin is stopped. Therefore, if the operation of the temperature sensor 51 is unstable or faulty, the movement of the beauty appliance may be stopped. Therefore, a sense of discomfort during use, such as overheating, due to a failure of the temperature sensor 51 can be avoided in advance.

(4) The main body 11 of the beauty instrument is provided with an extension portion 14. A power switch 26, a level switch 27, a mode indicator lamp 29, and a level indicator lamp 30 are disposed on the extension portion 14 side. Therefore, the space for disposing the switch and the lamp can be easily secured, and the switch can be easily operated by the thumb or the like as compared with the case where the switch is disposed in the center portion of the main body 11. Further, the presence of the protruding portion 14 makes the entire main body 11 asymmetric, and other electrical devices such as an electric razor that are mistakenly considered to be symmetric can be avoided. Further, functional components such as a circuit board can be easily mounted by using the internal space of the extension portion 14, and the beauty instrument can be made more functional.

(modification example)

The above embodiment can be modified as follows. Further, the above embodiments and the following modifications can be combined with each other within a range not technically contradictory to the technology.

The present invention is embodied in a beauty apparatus other than a beauty apparatus, for example, a beauty apparatus such as a muscle training apparatus using abdominal muscles of EMS having a plurality of electrodes.

The shape of the main body 11 is changed by removing the protruding portions 14 of the main body 11 or by providing a pair of protruding portions 14 on both sides of the main body.

The number of the first electrode 16, the second electrode 17, and the third electrode 18 as cosmetic electrodes was changed. For example, the first electrode 16, the second electrode 17, and the third electrode 18 are provided in plural numbers.

The first electrode 16, the second electrode 17, the third electrode 18, and the like, which are cosmetic electrodes, are formed in other shapes such as a substantially square shape and a substantially triangular shape.

In the above embodiment, a voltage for skin detection is applied between any of the first electrode 16, the second electrode 17, and the third electrode 18, to which a voltage is applied for beauty, and the fourth electrode 24. In contrast, a voltage for skin detection is applied between any of the first electrode 16, the second electrode 17, and the third electrode 18, which is in a state where no voltage for beauty treatment is applied, and the fourth electrode 24, although the skin is in contact with the skin.

The operation in one mode such as the PI mode and the operation in another mode or the operation in a plurality of modes are performed simultaneously. For example, if the PI mode and the RF mode are simultaneously operated, the possibility of the cosmetic ingredient permeating into the skin is increased.
