[0045] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0046] It should be noted that when a component is referred to as being "mounted on", "fixed on" or "disposed on" another component, it may be directly on the other component or there may be a central component at the same time. When a component is referred to as being "connected to" another component, it may be directly connected to the other component or there may be a central component at the same time.

[0047] It should also be noted that the directional terms such as left, right, up, and down in the embodiments of the present invention are merely relative concepts or are based on the normal use status of the product and should not be considered as restrictive.

[0048] See also Figure 1 , Figure 2 and Figure 3 The multifunctional beauty instrument provided by the present invention comprises a beauty instrument body 1, one end of which is provided with a plurality of electrodes (not numbered in the figure) and a color light array 20 provided below the electrodes, wherein at least two electrodes constitute an electrode pair, that is, at least one positive electrode and at least one negative electrode among the plurality of electrodes, or the polarity of the same electrode may be different at different times, such as the same electrode being a positive electrode at one time and a negative electrode at another time. The beauty instrument body 1 is provided with a control module 10 for controlling the working state of the electrode pair and the color light array 20 according to the functional mode, and each electrode and the color light array 20 are electrically connected to the control module 10.

[0049] Among them, the working state includes the power-on state and the power-on duration. The control module is specifically used to control the power-on state and the power-on duration of each electrode pair according to the function mode instruction issued by the user, and at the same time control the colored light array to output lights of corresponding colors, and when switching the function mode, time the current function mode, and when the set time of the current function mode is reached, or when the total working time reaches the set time, the electrode pairs and the colored light array are turned off.

[0050] For example, two adjacent electrodes form an electrode pair, and the control module 10 controls the power supply of each electrode pair in sequence according to the first functional instruction, and controls the colored light array 20 to emit the first colored light. The electrode pair can be an electrode pair composed of two adjacent electrodes, or an electrode pair composed of a pair of adjacent electrodes, in which one electrode is again composed of other adjacent electrodes, or several electrodes are of the same polarity and other electrodes are of another polarity, etc. The first colored light can be red and yellow light, which helps to promote collagen production. Specifically, the electrodes involved in the work can be the odd-numbered peripheral electrodes as positive electrodes and the even-numbered peripheral electrodes as negative electrodes, and the central electrode can be of any polarity or not involved in the work.

[0051] The present invention sets a plurality of electrodes at one end of the beauty instrument body 1, sets a colored light array 20 below the electrodes, and the control module 10 sequentially controls the power-on of each electrode pair according to the first functional instruction, so that the electrode pair is energized in turn to stimulate the user's skin, and at the same time controls the colored light array 20 to emit the first colored light, so that the beauty instrument has both the functions of electric stimulation massage and photon irradiation, and its functions are rich, preventing the skin from adapting, and reducing the user's purchase cost. In addition, when switching the function mode, the current function mode is timed, and when the set time of the current function mode is reached, or when the total working time reaches the set time, the electrode pair and the colored light array are turned off, so that the beauty instrument has both the functions of electric stimulation massage and photon irradiation, and the working time of each mode and the entire working time of the beauty instrument are controlled, so as to save power while ensuring the skin care effect.

[0052] In this embodiment, the first function instruction is used to make the multifunctional beauty instrument work in REJ (REJ stands for rejuvenation) mode, awakening the skin by changing the massage points. Optionally, the multiple electrodes include a central electrode M and multiple peripheral electrodes. In this embodiment, six peripheral electrodes are used, namely peripheral electrodes UL, UR, R, DR, DL, and L (it can also be understood that the peripheral electrodes include a first UL peripheral electrode, a second peripheral electrode UR, a third peripheral electrode R, a fourth peripheral electrode DR, a fifth peripheral electrode DL, and a sixth peripheral electrode L). The peripheral electrodes UL, UR, R, DR, DL, and L are arranged around the central electrode M. The colored light array 20 includes a plurality of LED lights arranged in the gaps between the electrodes, such as Figure 4 and Figure 5 shown.

[0053] Optionally, the central electrode M is circular, and the peripheral electrodes UL, UR, R, DR, DL, and L are fan-shaped, and the peripheral electrodes UL, UR, R, DR, DL, and L are arranged in a circular ring and arranged around the central electrode M. The central electrode M is relatively large, and the peripheral electrodes UL, UR, R, DR, DL, and L are relatively small, so that the contact area between the electrodes and the skin is different during massage. This massage method can resist aging and make the skin less likely to adapt. The beauty instrument body 1 is an inverted cone with a large top and a small bottom, which is convenient for human hands to hold during massage operation and can ensure a larger massage area.

[0054] Of course, in other embodiments, the peripheral electrodes UL, UR, R, DR, DL, L and the beauty instrument body 1 may also be in other shapes and other numbers. For example, there may be eight peripheral electrodes arranged in a rectangular array, and the beauty instrument body 1 may also be in a slightly curved column shape. The present invention is not limited to this.

[0055] The multifunctional beauty instrument of the present invention can adopt the method of electric pulse massage. When the control module 10 receives the first function instruction, the control module 10 controls a peripheral electrode and the central electrode M to be energized for a first preset time, then controls the peripheral electrode and the adjacent peripheral electrode to be energized for a second preset time, and then controls the adjacent peripheral electrode and the central electrode M to be energized for the first preset time, and then cycles in sequence. At the same time, when unloaded, the color light array outputs at a lower brightness, and when the detection electrode is in contact with the skin, the output brightness of the color light array is increased.

[0056] It can also be understood here that: the electrode pair is a central electrode M and a peripheral electrode (such as the first peripheral electrode UL) forming an electrode pair that is energized for the first preset time (such as 20ms), and the peripheral electrode (i.e., the first peripheral electrode UL) and another peripheral electrode (such as the second peripheral electrode UR) adjacent to the peripheral electrode (i.e., the first peripheral electrode UL) form another electrode pair that is energized for the second preset time (such as 10ms), and the other peripheral electrode (i.e., the second peripheral electrode UR) again forms an electrode pair with the central electrode M that is energized for the first preset time (such as 20ms), and then the second peripheral electrode UR and the third peripheral electrode R adjacent to it form an electrode pair that is energized for the second preset time (such as 10ms), and the cycle continues... During electrical stimulation massage, the method of alternating massage of adjacent massage points is used, which is beneficial to promote the metabolism of the massaged parts and achieve good massage effects.

[0057] In this embodiment, the second functional instruction is used to make the multifunctional beauty instrument work in R&S mode (i.e., radio frequency and ultrasound act simultaneously), and awaken the deep part of the skin through radio frequency and ultrasound energy. Further, the control module 10 controls each peripheral electrode UL, UR, R, DR, DL, L to output radio frequency energy according to the second functional instruction, and controls the central electrode M to output ultrasound energy when detecting that the central electrode is in contact with the skin, and controls the color light array 20 to emit a second color light, which can be purple light (i.e., red and blue LEDs are lit at the same time). Similarly, when unloaded, the color light array outputs at a lower brightness. When the electrode is detected to be in contact with the skin, the output brightness of the color light array is increased, and the central electrode M outputs ultrasound to massage the human body while irradiating red light, which has the effects of removing dullness and whitening the skin, further enriching the functions of the beauty instrument.

[0058] In addition to the above-mentioned working modes, the multifunctional beauty instrument of the present invention also has multiple modes, such as EMS mode. The control module makes one part of the electrodes positive and the other part of the electrodes negative to form an electrode pair according to the third functional instruction, and makes the electrode pair output muscle electrical stimulation microcurrent, and at the same time controls the colored light array to emit a third color light, which can be red light. Similarly, when idling, the colored light array outputs at a lower brightness. When the contact between the electrode and the skin is detected, the output brightness of the colored light array is increased. The EMS mode can make the user's skin tighter.

[0059] See also Figure 6 The control module 10 includes a function input unit 11, a main control unit 12, a frequency control unit 13 and a driving unit 14 having the same number as the electrodes. The main control unit 12 controls the working state of the frequency control unit 13 and the driving unit 14 according to the function instruction received by the function input unit 11, thereby controlling the power-on state and power-on duration of the corresponding electrode. The power-on state includes whether it is powered on, the type and frequency of the output electrical signal, etc.

[0060] In the present invention, each electrode is independently controlled by a driving unit 14, and the power-on sequence, power-on duration, and suspension duration can be varied to achieve massages of various effects and prevent the skin from adapting.

The resistor R3 is connected to the P36 pin of the microcontroller U1, the base of the second transistor Q2 is connected to the P37 pin of the microcontroller U1 through the fourth resistor R4, the A4 pin, A5 pin, A6 pin and A7 pin of the 8-way buffer U2 are all connected to the P22 pin of the microcontroller U1, the Y0 pin, Y1 pin, Y2 pin, Y5 pin, Y6 pin and Y7 pin of the 8-way buffer U2 are each connected to a driving unit 14 for driving peripheral electrodes, and the Y3 pin of the 8-way buffer U2 is connected to the driving unit 14 for driving the central electrode M.

[0064] The 8-way buffer U2 can use a chip model CD74HC541, and output high and low level states (i.e., control PWM_A signal and PWM_B signal to 0 or 1) and corresponding duty cycles through the P21 and P22 pins of the microcontroller U1 to control whether the corresponding output pins of the 8-way buffer U2 output and the operating frequency (i.e., control PA_UL signal, PA_R signal, PA_DL signal, PA_UR signal, PA_L signal, and PA_DR signal to 0 or 1 and the corresponding frequency), so that the corresponding peripheral electrodes output corresponding electrical signals. The P36 and P37 pins of the microcontroller U1 output high and low level states and corresponding duty cycles to control whether the Y3 pin output pin of the 8-way buffer U2 outputs and the operating frequency (i.e., PA_M signal to 0 or 1 and the corresponding frequency), so that the intermediate electrode outputs corresponding electrical signals.

When the HO pin and the LO pin of the MOS driving chip U3 output a high level, the MOS transistor is turned on to energize the corresponding electrode, even if the electrode ( Figure 7 To energize the peripheral electrode DR).

[0067] Since the seven drive units 14 can adopt the same circuit structure, the present invention only exemplifies one of the drive circuits in detail. The working states of the seven drive units 14 are all controlled by the microcontroller U1. Specifically, the P23, P02, P24, P26, P20, P45, and P03 pins of the microcontroller U1 can be controlled to respectively control the power-on state and power-on and power-off time of the electrodes UL, UR, R, DR, DL, L, and M. If the P23 pin outputs a high level, the electrode UL is energized to output current; otherwise, the P23 pin outputs a low level, the electrode UL is left floating, and the working frequency of each circuit is controlled accordingly by the 8-way buffer U2.

When the central electrode M is not in contact with the skin, the central electrode M does not work. When the central electrode M is detected to be in contact with the skin, the current fluctuation signal at both ends of the fourteenth resistor R14 is input to the 5th pin of the OK06 op amp chip U4 through the fifteenth resistor R15. Since the 7th pin output end of the OK06 op amp chip U4 is connected to the inverting input end 6th pin through the sixteenth resistor R16, a negative feedback mode is formed, so that the op amp chip is in an amplification state, and the signal is input through the 5th pin and output to the P44 pin of the microprocessor at the 7th pin. When the amplification factor reaches 1+R16 / R18, the op amp chip is in a stable state. That is, the maximum amplification state. The P44 pin of the microprocessor detects the output of the 7th pin of the op amp chip, and controls the working state of the drive unit 14 through the signal coupled by the seventeenth resistor R17, thereby stabilizing the thermal energy consumption of the electrode.

[0075] Please continue reading Figure 2 and Figure 6The function input unit 11 includes a switch / mode switching key SW1, a gear key SW2 and a color light switching key SW3, and the switch / mode switching key SW1, the gear key SW2 and the color light switching key SW3 are respectively connected to the P35 pin, the P34 pin and the P33 pin of the microcontroller U1.

[0076] The switch / mode switch key SW1, the gear key SW2 and the color light switch key SW3 can be a key switch or a touch switch. The IO port (such as P35 pin, P34 pin and P33 pin) of the microcontroller U1 is interrupted by the number of presses or touches, and the relevant functions can be controlled according to the number of interruptions. For example: the switch / mode switch key SW1 turns on the beauty instrument when the microcontroller U1 is interrupted for the first time, the beauty instrument enters the REJ mode when the second interruption occurs, and the beauty instrument enters the ultrasonic mode when the third interruption occurs. The color light switch key SW3 can also switch the working mode of the color light array when the beauty instrument is working, such as switching the red and yellow light in the REJ mode state to red light, etc.

[0077] Furthermore, when controlling the gear or function, the present invention also provides a corresponding indicator light to indicate the working status of the beauty instrument. Figure 2 , Figure 6 and Fig. 9 The control module 10 also includes a gear indicating unit 16 and a mode indicating unit 17. One end of the gear indicating unit 16 and the mode indicating unit 17 are connected to the LED column driving pin of the microcontroller U1, and the other end of the gear indicating unit 16 and the mode indicating unit 17 are connected to the LED row driving pin of the microcontroller U1.

[0078] In this embodiment, the gear indication unit 16 and the mode indication unit 17 both include a RYB three-color LED (red, yellow, and blue) matrix. The row signal is controlled by the P14, P16, and P17 pins of the microcontroller U1, and the column signal is controlled by the P13, P12, P31, and P32 pins of the microcontroller U1. By making the corresponding column signal a high level and the row signal a low level, the corresponding three-color LED displays the corresponding color. For example, when the gear instruction is the second gear, the gear indication unit 16 lights up two three-color LEDs accordingly.

[0079] Preferably, the area on the beauty instrument body 1 where the gear indication unit 16 and the mode indication unit 17 are located is a light-transmitting area. When the corresponding LED light is turned on, the area shows the corresponding color. When the LED light is turned off, the area is a display light, thereby providing the beauty instrument body 1 with beautiful appearance and a sense of technology with the light coordination.

[0080] Please also refer to Figure 4 , Figure 5 , Figure 6 and Fig.10The colored light array 20 includes a number of RYB three-color LED (red, yellow, and blue) lights. The positive electrode of the colored light array 20 is powered by the battery output voltage VB, and the negative electrode of the colored light array 20 is controlled by the P50 pin, P51 pin, and P55 pin of the microcontroller U1 to output a low level to control the lighting of the three colors of red, yellow, and blue respectively. The P50 pin, P51 pin, and P55 pin can output a low level at the same time, and can also choose to light up one color or two colors.

[0081] Furthermore, the multifunctional beauty instrument provided by the present invention also includes a buzzer module 40, which is connected to the P47 pin of the microcontroller U1. When the power is turned on, the microcontroller U1 is powered on, and the P47 pin outputs a high level to make the buzzer output a "beep" sound. Of course, the buzzer also sounds when the switch / mode switching key SW1, the gear key SW2 and the color light switching key SW3 are pressed to prompt that the key operation is successful.

[0082] Furthermore, the beauty instrument of the present invention also includes a base 2, which can be connected to an external power plug to charge the beauty instrument body 1, and can also serve as a base to place the beauty instrument body 1, which is larger at the top and smaller at the bottom, to facilitate the placement of the beauty instrument body 1 and prevent the beauty instrument body 1 from falling and breaking.

[0083] In order to better understand the present invention, the following Figures 1 to 10 The working mode of the multifunctional beauty instrument of the present invention is described in detail:

[0084] Long press the switch / mode switch key SW1 to turn on the beauty instrument. When it is turned on, the default EMS function and gear are in the first gear. At this time, the electrodes UL, R, and DL are connected as one pole, the electrodes UR, DR, and L are connected as one pole, and the central electrode M does not participate in the work. The EMS frequency is 100HZ. In the EMS working mode, you can press the gear key SW2 to switch the gear, or press the color light switch key SW3 to switch the light color; in the EMS mode, when the electrode is not in contact with the skin, the color light array emits light at a lower brightness. When the electrode is detected to be in contact with the skin, the driving current of the drive unit is increased to increase the color light array and improve the lighting function. The setting time in this mode can be 4 minutes. After working in the EMS mode for 4 minutes, the beauty instrument turns off. When switching modes, the timing starts from the new function mode. When switching lights, the timing is not restarted.

[0085] When the switch / mode button is pressed again, the working mode of the beauty instrument switches to REJ mode, and the working frequency is 80-110KHz. When working, the electrodes UL and M can be made to work simultaneously for 20ms, then the electrodes UL and UR can be made to work simultaneously for 10ms, then the electrodes UR and M can be made to work simultaneously for 20ms, then the electrodes UR and R can be made to work simultaneously for 10ms, then the electrodes R and M can be made to work simultaneously for 20ms, then the electrodes R and DR can be made to work simultaneously for 10ms, then the electrodes DR and M can be made to work simultaneously for 20ms, then the electrodes DR and DL can be made to work simultaneously for 10ms, then the electrodes DL and M can be made to work simultaneously for 20ms, then the electrodes DL and L can be made to work simultaneously for 10ms, then the electrodes L and M can be made to work simultaneously for 20ms, then the electrodes L and UL can be made to work simultaneously for 10ms, and this cycle can be repeated. Similarly, in REJ mode, when the electrodes are not in contact with the skin, the colored light array emits light at a lower brightness. When the electrodes are detected to be in contact with the skin, the driving current of the driving unit is increased to increase the colored light array and enhance the lighting function. The setting time in this mode can also be 4 minutes. The beauty instrument will shut down after working in REJ mode for 4 minutes. When switching modes, the timing will start from the new function mode. When switching lights, the timing will not be restarted.

[0086] When the switch / mode key is pressed again, the beauty instrument working mode switches to R&S mode, and the P44 pin of the microcontroller U1 can control the peripheral electrodes UL, UR, R, DR, DL, and L to work in the radio frequency mode, outputting radio frequency signals with a frequency of 290KHz-310KHz. When the central electrode M is not in contact with the skin, the central electrode M does not work or outputs with a small function. When the central electrode M is detected to be in contact with the skin, the OK06 op amp chip U4 amplifies the input signal to control the corresponding driver chip to increase the output current, so that the central electrode M outputs an ultrasonic signal with a frequency of about 3MHz at normal power. Similarly, the setting time in this mode is 4 minutes. Within 4 minutes of each function mode being activated, if the user continuously switches the function mode, the total working time will not exceed 12 minutes.

[0087] In summary, the present invention arranges multiple electrodes at one end of the beauty instrument body and arranges a colored light array under the electrode so that at least two electrodes constitute an electrode pair. The control module controls the power-on state and power-on time of each electrode pair according to the function mode instruction issued by the user, and controls the colored light array to output lights of corresponding colors. When switching the function mode, the current function mode is timed. When the set time of the current function mode is reached, or when the total working time reaches the set time, the electrode pair and the colored light array are turned off, so that the beauty instrument has both electric stimulation massage and photon irradiation functions, and controls the working time of each mode and the entire working time of the beauty instrument, so as to save power while ensuring the skin care effect. It has rich functions, prevents the skin from adapting, and reduces the purchase cost for users.

[0088] In addition, the electrode working modes include EMS, REJ, RF, and ultrasonic modes, and the color light also includes red, yellow, blue and a combination of any two or three colors. The electric pulse and color light functions are rich and can achieve good phototherapy skin care effects.

[0089] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of the present invention, and all these changes or substitutions should fall within the protection scope of the claims attached to the present invention.
