Description

Electronic device and control method thereof

Technical Field

The present invention belongs to the field of medical equipment, and in particular relates to an electronic device and a control method thereof.

Background technique

When dealing with the "early aging" of the skin, such as dryness and dehydration, loss of collagen, and slow metabolism, current electronic devices use radio frequency technology and microcurrent technology to promote collagen synthesis, accelerate skin metabolism, and use ion introduction technology to promote the penetration of skin care products, help the skin moisturize and lock in moisture, and improve rough skin problems.

Since the alternating synergy of the two functions of radio frequency and microcurrent can achieve better results, the current electronic devices that focus on anti-aging mainly use radio frequency and microcurrent technology, but usually use radio frequency and microcurrent as separate functions or devices. Even if radio frequency and microcurrent are integrated on the same electronic device at the same time, the radio frequency component and the microcurrent component are set at different positions on the electronic device. When switching functions, the hand-held method needs to be changed, which is particularly inconvenient to operate. In addition, there are some problems with the efficacy and safety of existing electronic devices. At present, most radio frequency design parameters are low frequency and high power. The actual output heat energy cannot reach the depth of the dermis and affects the efficacy of use. At the same time, low frequency and high power may also cause skin burns and reduce safety. Furthermore, most of the existing electronic devices do not monitor the output of microcurrent, and cannot ensure that the output microcurrent will always be within the safe range. If the device is abnormal and the microcurrent exceeds the safety threshold, it will not only have a counter-effect, stimulate the facial nerves, trigger facial muscle movement, and make the muscles develop unevenly, but also bring pain to the user due to current stimulation, and may even cause muscle damage.

In addition, for skin rejuvenation, it is also very important to effectively promote the penetration and absorption of the effective ingredients of skin care products. It should be noted that when no electronic devices are used, the penetration rate of skin care products generally does not exceed 2%. Therefore, the absorption rate of the effective ingredients of skin care products by the skin is very low, and the efficacy of skin care products is not very great. However, most electronic devices currently do not contain the function of promoting the penetration and absorption of the effective ingredients of skin care products (referred to as penetration promotion). For example, some electronic devices use radio frequency heating to stimulate the dermis to promote the absorption of skin care products by cells, but skin care products cannot penetrate through the stratum corneum of the skin barrier, and the skin care effect is minimal. Some electronic devices also have ion introduction function, but due to its mechanism of action, ion introduction is not very effective for skin care products that promote penetration. There are certain limitations in the electrophoretic migration of weakly charged and uncharged compounds. Therefore, it is difficult for ion introduction to achieve the effect of promoting the penetration of large molecular weight skin care product ingredients.

Summary of the invention

The purpose of the present invention is to provide an electronic device and a control method thereof, which not only realizes the alternating synergy of radio frequency and microcurrent to achieve the effect of lifting and tightening the skin, but also realizes the alternating synergy of electroporation and ion introduction to promote the penetration and absorption of effective ingredients in skin care products.

FIG1 schematically shows a front view of an electronic device according to an embodiment of the present invention, and FIG2 schematically shows an internal view of an electronic device according to an embodiment of the present invention.

As shown in Figures 1 and 2, the electronic device 10 provided in an embodiment of the present invention includes a working head 21 and a body 22. The working head 21 is arranged at one end of the body 22. The outer surface (including the end face and/or the side face) of the working head 21 is in direct contact with the target area. An electrode assembly is arranged on the working head 21, and the electrode assembly is used to output energy. The working head 21 can rotate or not rotate relative to the body 22. The end face of the working head 21 is preferably not perpendicular to the axis of the body 22, forming a certain angle, generally forming an angle of 15°, which conforms to the ergonomic design and makes it more comfortable and convenient to use. The body 22 is used as both a handle and as the core control part of the electronic device 10, which can control the working state of the entire electronic device 10. The electronic device 10 of this embodiment can be used as a portable beauty instrument.

As shown in FIG5 , the electronic device 10 further includes an input device 11, a power supply device 12 and an energy output device 14, and preferably further includes a control device 13 and/or a detection device 15. In one embodiment, the control device 13 is used to output a square wave with a fixed duty cycle as a signal source for the energy output device 14. Preferably, the control device 13 is connected to the input device 11, the power supply device 12 and the energy output device 14. Preferably, the control device 13 is also connected to the detection device 15. The detection device 15 is also connected to the energy output device 14 and the power supply device 12. The power supply device 12, as the power supply part of the entire electronic device 10, can supply power to the input device 11 and the energy output device 14. Preferably, the power supply device 12 also supplies power to the control device 13 and the detection device 15.

The input device 11 is an interface for the electronic device 10 to communicate with the user, and is configured to generate input information according to the instructions input by the user. The input device 11 can be various suitable input interfaces such as buttons, touch screens, etc. The input information may include input information corresponding to the working mode of the electronic device 10 and/or input information corresponding to the gear position in the working mode.

The electronic device 10 has a radio frequency microcurrent working mode and an electroporation ion introduction working mode, and preferably also has a skin detection working mode and a refrigeration working mode. When using the electronic device 10, the corresponding working mode can be selected through the input device 11, so that the electronic device 10 starts the corresponding working mode according to the instructions input from the outside. For example, for different skin types, including normal skin, sensitive skin and tolerant skin, the electronic device 10 can choose to output different energy intensities (such as output power), and can also output different energy intensities for different skin parts. For the skin around the eyes, low power output can be selected, and for the facial skin, high power output can be selected.

As shown in FIG. 2 and FIG. 3 b, the energy output device 14 includes at least one electrode assembly 145, which is disposed on the working head 21. The electrode assembly 145 includes two electrodes, which are usually two electrode sheets with opposite polarities. In this embodiment, each electrode assembly 145 is composed of two electrode sheets with opposite polarities. The electrodes are insulated to avoid mutual conduction.

The energy output device 14 is used to selectively start one of the radio frequency microcurrent working mode and the electroporation ion introduction working mode according to the input information. In the radio frequency microcurrent working mode, the energy output device 14 alternately outputs radio frequency and microcurrent through the same electrode assembly 145; in the electroporation ion introduction working mode, the energy output device 14 alternately outputs electroporation pulses and ion introduction currents through the same electrode assembly 145. Among them, radio frequency, microcurrent, electroporation pulses and ion introduction currents The outputs of the energy output device 14 share the same electrode assembly 145. The energy output device 14 can share one electrode assembly 145 to alternately output these energies, or can share multiple electrode assemblies 145, and each electrode assembly 145 of the multiple electrode assemblies 145 can alternately output these energies. After such a setting, it is avoided to configure different electrode assemblies 145 for the output of different energies, thereby simplifying the structure, and there is no need to change the hand-held mode when switching functions, which increases the convenience of using the electronic device, and also helps the electronic device to fully exert its effectiveness. It should be noted that radio frequency and microcurrent are used in combination, and the alternating synergistic effect of radio frequency and microcurrent can make the skin lifting and tightening effect better, and electroporation pulses and ion introduction are also used in combination. The two serve as another set of energy to alternately synergize to achieve the effect of promoting the penetration of skin care products and significantly improve skin condition.

The electronic device 10 provided by the present invention can be applicable to various skin parts, such as the jaw, apple muscles, eye area, forehead and the like.

It should also be noted that even if the existing radio frequency beauty instrument has two functions of radio frequency and microcurrent, radio frequency and microcurrent are used as two independent functions, and the two energies do not work in alternating synergy, and radio frequency and microcurrent are output by different electrode assemblies respectively. When set in this way, not only does the user need to flip the instrument when switching functions, which is very inconvenient to use, but also radio frequency and microcurrent work independently, making it difficult to achieve a good therapeutic effect on skin lifting and tightening. The electronic device 10 provided by the present invention no longer uses radio frequency and microcurrent as two independent functions, and realizes the alternating synergy of radio frequency and microcurrent, which has a better therapeutic effect. During treatment, the radio frequency current output by the electronic device 10 heats the dermis skin, causing collagen to shrink and denature and produce a healing reaction, while the output microcurrent promotes the generation of ATP (adenosine phosphate, an energy substance required for the production of collagen and elastin), thereby accelerating the repair and healing after radio frequency heating of the dermis, promoting the synthesis of collagen and elastin, and achieving the significant effect of reducing fine lines, improving skin roughness, and increasing collagen density.

This application does not make any special requirements on the frequency of alternating output of radio frequency and microcurrent, nor does it limit the frequency of alternating output of electroporation and ion introduction. For example, in the radio frequency microcurrent working mode, after 10 seconds of radio frequency output, microcurrent output is 5 seconds, followed by 10 seconds of radio frequency output and 5 seconds of microcurrent output, and the radio frequency and microcurrent are output in an alternating cycle. However, the interval time of alternating output of radio frequency and microcurrent here is only for illustration and is not intended to limit the present invention. In general, the radio frequency output time should be greater than the microcurrent output time, and the combined use of the two has a good effect. For example, in the electroporation ion introduction working mode, the electroporation pulse output After 10 seconds, the iontophoresis output is 20 seconds, followed by the electroporation pulse output for 10 seconds, and the iontophoresis output for 20 seconds, so that the electroporation pulse and the iontophoresis current are output in an alternating cycle. However, the interval time between the alternating output of the electroporation pulse and the iontophoresis is only for illustration and is not intended to limit the present invention. Generally, the electroporation pulse output time is shorter than the iontophoresis output time, and the combined use of the two has a good effect.

The number of electrode assemblies 145 is preferably multiple, such as 2 or more than 2, and all electrode assemblies 145 are arranged on the working head 21. In some embodiments, at least two electrode assemblies 145 are of different sizes to facilitate outputting different energy intensities. And/or, in some embodiments, the positions of at least two electrode assemblies 145 are asymmetric so that different target areas can be treated with different electrode assemblies 145 to ensure the use effect. Therefore, a small electrode can be used to output energy for thinner skin, and a large electrode can be used to output energy for thicker skin.

Taking two electrode assemblies 145 as an example, as shown in FIG. 2 and FIG. 3 b , the two electrode assemblies 145 are respectively a first electrode assembly 1451 and a second electrode assembly 1452. In the illustrated embodiment, the electrode size in the first electrode assembly 1451 is larger than the electrode size in the second electrode assembly 1452, that is, the first electrode assembly 1451 uses a large electrode and the second electrode assembly 1452 uses a small electrode. The large electrode is used for target areas with thicker skin, such as the face, while the small electrode is used for target areas with thinner skin, such as the skin around the eyes. Preferably, the positions of the first electrode assembly 1451 and the second electrode assembly 1452 are asymmetrical, such as the first electrode assembly 1451 is arranged on the end face of the working head 21, and the second electrode assembly 1452 is arranged on the side of the working head 21, so that it is convenient to use different electrode assemblies for treatment of different target areas. Usually, electrode assemblies 145 of different sizes and/or asymmetrical positions are not used at the same time. The number of the first electrode assemblies 1451 and the second electrode assemblies 1452 can be various, for example, the number of the first electrode assemblies 1451 can be 2 to 4, and the number of the second electrode assemblies 1452 can be 1 to 2.

It should be noted that conventional radio frequency beauty devices use one or more pairs of positive and negative electrodes, and the electrodes are of the same size and symmetrically positioned. As body contact electrodes, such electrodes are usually suitable for acting on relatively flat skin such as cheeks, but are not convenient for close fit around the eyes, which will affect the use effect, and may not be able to contact relatively uneven skin such as the nose. The present invention is applied to different skin surfaces, and electrode assemblies 145 of different sizes and/or asymmetrical positions are provided to be suitable for the treatment of different target areas, thereby increasing the treatment area and ensuring the use effect and safety.

As shown in FIG. 3b , in one embodiment, the first electrode assembly 1451 includes two concentrically arranged The ring electrode is a double-ring large electrode with opposite polarities, preferably a circular ring electrode sheet. The two ring electrodes are arranged on the end surface of the working head 21. Preferably, the width of each ring electrode is 3mm to 5mm, and the spacing between the two ring electrodes is 3.5mm to 4.5mm. This spacing can assist the radio frequency energy to reach the position of 2mm to 3mm below the skin, and can be used for relatively flat skin parts such as cheeks, with a large coverage area and high output energy.

As shown in FIG. 3b, in one embodiment, the second electrode assembly 1452 includes two L-shaped electrodes with arc-shaped outer surfaces, and the polarities of the two L-shaped electrodes are opposite. Preferably, the radius of the arc corner of each L-shaped electrode is greater than 2.5 mm, and the spacing between the two L-shaped electrodes is 3 mm to 6 mm, arranged at the edge of the working head 21. The arrangement of the L-shaped electrodes allows the electrodes in the second electrode assembly 1452 to extend from the horizontal direction to the vertical direction. On the one hand, it can have good contact with the skin when held and slid at will during use, and on the other hand, it can also fit tightly when acting on relatively uneven parts such as the nose wing. Preferably, the first electrode assembly 1451 and the second electrode assembly 1452 are integrally formed by an in-mold injection molding process to ensure the waterproof performance of the electronic device 10.

Preferably, the control device 13 controls the energy output device 14 to alternately output radio frequency and micro current, or alternately output electroporation pulse and ion introduction current according to the input information. The frequency of the alternating output of radio frequency and micro current and the frequency of the alternating output of electroporation pulse and ion introduction current can be preset by the control device 13 or can be set by the user, and the alternating output frequency can be fixed or adjustable.

In a preferred embodiment, the detection device 15 is used to obtain the output information of the energy output device 14. The detection device 15 can continuously and uninterruptedly detect the output information of the energy output device 14 in real time, or it can intermittently detect the output information of the energy output device 14. The output information can be any output value that can reflect the current output state of the energy output device 14. The output value can be any data such as voltage, temperature, current, etc. For radio frequency output, the detection device 15 mainly detects the skin surface temperature. If the skin surface temperature is detected to exceed the limit temperature that the skin can tolerate (the limit temperature is generally 43°C), corresponding safety handling measures need to be taken. For microcurrent, electroporation and ion introduction output, the detection device 15 mainly detects the current. If the detected current exceeds the safety threshold, corresponding safety handling measures are taken. The safety handling measures can be a voltage reduction output or a stop output to reduce the risk of burns, pain or even muscle damage to the user. The safety handling measures can also be voice Tips, light prompts, etc.

In a preferred embodiment, the control device 13 is used to obtain the system safety result about the output state of the energy output device 14 according to the output information obtained by the detection device 15, and generate corresponding safety processing measures according to the system safety result and the preset safety strategy. Preferably, the control device 13 is used to obtain the output value in the output information, and compare the output value with the safety threshold; if the comparison result is that the output value exceeds the safety threshold, the control device 13 obtains the system safety result that the energy output device 14 is in abnormal output, and generates a safety processing measure to control the power supply device 12 to reduce the output or stop the output in combination with the preset safety strategy. At this time, monitoring is set for the output of any kind of energy, so that the output of each kind of energy becomes safe and controllable, thereby improving the safety of the use of the electronic device 10.

As shown in FIG6 , in addition to the electrode assembly 145, in one embodiment, the energy output device 14 further includes a switching device 141, a radio frequency generator 142, a microcurrent ion introduction generator 143, and an electroporation generator 144. The switching device 141 is selectively connected to one of the radio frequency generator 142, the microcurrent ion introduction generator 143, and the electroporation generator 144. At least one electrode assembly 145 is connected to the radio frequency generator 142, the microcurrent ion introduction generator 143, and the electroporation generator 144. In one embodiment, the output ends of the radio frequency generator 142, the microcurrent ion introduction generator 143, and the electroporation generator 144 are selectively connected to one of the first electrode assembly 1451 and the second electrode assembly 1452. The radio frequency generator 142 is used to output radio frequency. The microcurrent ion introduction generator 143 is used to output a pulse current corresponding to the microcurrent, and is also used to generate an ion introduction current. The electroporation generator 144 is used to output an electroporation pulse. Therefore, the output of the ion introduction current and the output of the microcurrent share a microcurrent ion introduction generating device 143, thereby further simplifying the structure and simplifying the hardware design. The switching device 141 is connected to the control device 13, and under the control of the control device 13, it is selectively connected to one of the radio frequency generating device 142, the microcurrent ion introduction generating device 143 and the electroporation generating device 144.

In one embodiment, when the radio frequency generating device 142 is connected to the larger first electrode assembly 1451, a high frequency output can be used, preferably a radio frequency of 2 MHz to 4 MHz. At this time, the radio frequency energy can reach the dermis layer of 2 mm to 3 mm for target areas with thicker skin (such as the face).

In one embodiment, when the RF generator 142 is connected to the second electrode assembly 1452 with a smaller size, When using it, low frequency output can be used, preferably 1MHz to 2MHz radio frequency. At this time, the radio frequency energy can reach the subcutaneous depth for target areas with thinner skin (such as around the eyes).

Therefore, the electronic device 10 of the present invention can select electrode assemblies 145 of different sizes according to different target areas to output radio frequencies of different intensities, thereby increasing the safety and effectiveness of use.

As shown in FIG7 , in one embodiment, the switching device 141 includes two relays, the first relay 1411 and the second relay 1412. The first relay 1411 is selectively connected to one of the radio frequency generator 142 and the microcurrent ion introduction generator 143. The second relay 1412 is selectively connected to one of the microcurrent ion introduction generator 143 and the electroporation generator 144. Both relays are connected to the control device 13, so that the first relay 1411 is selectively connected to one of the radio frequency generator 142 and the microcurrent ion introduction generator 143 under the control of the control device 13, and the second relay 1412 is selectively connected to one of the microcurrent ion introduction generator 143 and the electroporation generator 144 under the control of the control device 13. When the user selects the working mode, if the radio frequency microcurrent working mode is selected, the first relay 1411 switches the radio frequency and microcurrent alternating output under the control of the control device 13, and if the electroporation ion introduction working mode is selected, the second relay 1412 switches the electroporation and ion introduction alternating output under the control of the control device 13. In other implementations of the present application, the switching device 141 may also be implemented by a relay.

Next, the working method of the electronic device 10 is further described by taking the first electrode assembly 1451 as a large electrode and the second electrode assembly 1452 as a small electrode as an example.

In one embodiment, the radio frequency microcurrent working mode includes a first working mode corresponding to the first electrode assembly 1451 and a second working mode corresponding to the second electrode assembly 1452 .

In the first working mode of radio frequency microcurrent, the radio frequency generator 142 is used to output a radio frequency of 2MHz to 4MHz, and the microcurrent ion introduction generator 143 is used to output a microcurrent of 335μA to 500μA. At this time, for target areas with thicker skin, the combined application of radio frequency and microcurrent technologies is more effective and also takes safety into consideration. It should be understood that when the output of radio frequency is limited to 2MHz to 4MHz, it not only ensures that the radio frequency energy can reach the depth of the skin, but also ensures the safety of use. It should be noted that the radio frequency frequency will affect the depth of radio frequency energy reaching the skin, and 2MHz to 4MHz is the safe energy range that the electronic device 10 of the present invention can accept for thicker skin such as the face. When the output of microcurrent is limited to 335μA to 500μA, it can avoid the stimulation and damage of the skin caused by larger currents. Because a larger current may have a counter-effect, stimulating the facial nerves and causing muscle damage. Furthermore, experiments have shown that the combined use of 335μA to 500μA microcurrent and 2MHz to 4MHz radio frequency can also achieve better therapeutic effects, and has outstanding effects on lifting and tightening the skin in thicker skin areas such as the face. Compared with the prior art, the electronic device 10 provided by the present invention can generate higher frequency radio frequencies, and the actual output heat energy can reach the depth of the dermis to ensure the efficacy of use.

In the second working mode of radio frequency microcurrent, the radio frequency generator 142 is used to output a radio frequency of 1MHz to 2MHz, and the microcurrent ion introduction generator 143 is used to output a microcurrent of 335μA to 500μA. At this time, for target areas with thinner skin, the combined application of radio frequency and microcurrent technologies has a better effect and also ensures safety. It should be understood that 1MHz to 2MHz is the safe energy range that the electronic device 10 can accept for thinner skin such as around the eyes. Therefore, when the output of radio frequency is limited to 1MHz to 2MHz, it not only ensures that the radio frequency energy reaches the depth of the skin, but also ensures the safety of use. Similarly, experiments have shown that the combined use of 335μA to 500μA microcurrent and 1MHz to 2MHz radio frequency can achieve better therapeutic effects, and has outstanding effects on lifting and tightening the skin in thinner skin areas such as around the eyes.

It should also be understood that conventional radio frequency beauty devices do not differentiate between the energy around the eyes and the face. For example, for the area around the eyes, high radio frequency output will be used, causing damage to the skin around the eyes. However, the present invention sets different energy intensities for different target areas, effectively ensuring the safety of use and reducing the risk factor during use.

In one embodiment, the electroporation ion introduction working mode may only include the first working mode corresponding to the first electrode assembly 1451, without the second working mode corresponding to the second electrode assembly 1452. In other embodiments, the electroporation ion introduction mode includes the first working mode corresponding to the first electrode assembly 1451 and the second working mode corresponding to the second electrode assembly 1452.

In the first working mode of electroporation ion introduction, the electroporation generator 144 is used to output an electroporation pulse with a voltage of 40V to 60V, a PWM-adjusted pulse width of 10ms to 20ms, and a pulse frequency of 20pps to 30pps, and the microcurrent ion introduction generator 143 is used to output an ion introduction current with a current density of 200μA/ ^cm2 to 500μA/ ^cm2 . The first working mode of electroporation ion introduction is mainly aimed at target areas with thicker skin, and considering safety, user experience, and skin tolerance, the voltage of the electroporation pulse is set to 40V to 60V, the pulse width is 10ms to 20ms, and the pulse frequency is 20pps to 30pps. The ion introduction current density is set to 200μA/cm ² ~ 500μA/cm ² , and experiments have shown that the combined use of electroporation and ion introduction under these specific parameters can effectively promote the penetration and absorption of the functional ingredients in skin care products in thicker skin areas, and the use effect is good.

In the second working mode of electroporation ion introduction, the electroporation generating device 144 is used to output an electroporation pulse current with a voltage of 10V to 20V, a PWM-adjusted pulse width of 5ms to 10ms, and a pulse frequency of 10pps to 20pps, and the microcurrent ion introduction generating device 143 is used to output an ion introduction current with a current density of 100μA/cm ² to 200μA/cm ^2. The second working mode of electroporation ion introduction is mainly aimed at target areas with thinner skin. Also from the perspectives of safety, user experience, and skin tolerance, the voltage of the electroporation pulse is set to 10V to 20V, the pulse width is 5ms to 10ms, and the pulse frequency is 10pps to 20pps, and the ion introduction current density is set to 100μA/cm ² to 200μA/cm ^2. Experiments have shown that the combined use of electroporation and ion introduction under these specific parameters can effectively promote the penetration and absorption of the functional ingredients in skin care products for thinner skin areas, and the use effect is good.

Therefore, the above two working modes of electroporation ion introduction also solve the problem of treating different skin parts. They are not only more flexible to use, but also increase safety and effectiveness and improve user experience.

Furthermore, after the electronic device 10 is turned on, the energy output device 14 can be started only after the working head 21 has contacted the skin, that is, the electronic device 10 will output energy only when the electrodes on the working head 21 contact the skin. Doing so not only saves electricity but also improves safety.

In one embodiment, after the electronic device 10 is turned on, the detection device 15 automatically detects the load resistance (i.e., skin impedance) of the target object (skin) and sends the detected load resistance to the control device 13. The control device 13 determines whether to start the energy output device 14 based on the detected load resistance. For example, the control device 13 compares the load resistance with the preset resistance. When the two are the same, the control device 13 controls the switching device 141 to turn on the energy output device 14. Therefore, the electronic device 10 also has a power-on detection function. After the electronic device 10 is turned on, the detection device 15 first automatically obtains the skin impedance, and the control device 13 compares the skin impedance with the preset load resistance, and obtains the system safety result about the contact state of the electronic device 10. If the system safety result about the contact state of the electronic device is that the working head 21 is not currently in contact with the skin, then according to the preset safety strategy, the safety processing measure of locking the energy output device 14 is executed, and no energy is output. If the system safety result about the contact state of the electronic device is that the working head 21 is not currently in contact with the skin, then according to the preset safety strategy, the safety processing measure of locking the energy output device 14 is executed, and no energy is output. 21 has currently contacted the skin, then according to the preset safety strategy, the safety treatment measures of opening the energy output device 14 are executed.

As shown in FIG8 , in one embodiment, the power supply device 12 includes a battery 121 for storing electrical energy, which can be charged. The battery 121 is generally a lithium battery. Since the maximum voltage output by a lithium battery is usually no more than 4.2V, in order to meet different power supply requirements, the voltage output by the lithium battery needs to be stepped down or stepped up. To this end, in one embodiment, the power supply device 12 also includes a voltage regulator 122 for adjusting the voltage output by the battery 121 to increase the voltage output by the battery 121 or reduce the voltage output by the battery 121.

In a specific embodiment, the voltage regulator 122 can adjust the output voltage of the battery 121 to 5.5V-18V (preferably 13.3V) and supply power to the energy output device 14 .

In a specific embodiment, the voltage regulator 122 can also adjust the output voltage of the battery 121 to 3.3V-5V (preferably 3.3V), and supply power to the MCU (micro control unit) in the control device 13. The MCU in the control device 13 can control the relay.

In a specific embodiment, the voltage regulator 122 can also adjust the output voltage of the battery 121 to 3V-12V (preferably 5V) and supply power to the relay.

In one embodiment, the voltage regulator 122 includes a boost component and a buck component. The boost component is used to increase the voltage output by the battery 121. The boost component can be a DC-DC boost chip. The buck component is used to reduce the voltage output by the battery 121. The buck component can be an LDO buck chip.

The present embodiment has no particular restrictions on the type of the control device 13, which may be hardware that performs logical operations, such as a single-chip microcomputer, a microprocessor, a programmable logic controller (PLC) or a field-programmable gate array (FPGA), or a software program, functional module, function, object library or dynamic link library that implements the above functions based on hardware. Moreover, those skilled in the art can understand how the control device 13 controls the switching process of the switching device 141 based on the prior art, and can also understand how the control device 13 communicates with other devices (such as the detection device 15, the LED light-emitting device 23, the refrigeration device 24, the skin detection device 25, the display device 26, and the sound prompt device 27) based on the prior art. The present embodiment has no particular restrictions on the type of the detection device 15, such as: a temperature sensor, a current sensor, a voltage sensor, etc. Detection device 15 usually includes multiple sensors to detect different data.

As shown in FIG8 , in one embodiment, the RF generating device 142 includes a RF generating component 1421 and a transformer 1422. The RF generating component 1421 is used to directly connect the first relay 1411. The output end of the RF generating component 1421 is connected to the transformer 1422, and the output end of the transformer 1422 is directly connected to the electrode assembly 145.

When the first relay 1411 is connected to the RF generating component 1421, the RF generating component 1421 converts the square wave output by the control device 13 into a sine wave and outputs it to the transformer 1422. The transformer 1422 amplifies and boosts the sine wave and outputs it to the electrode assembly 145 as a RF signal. Finally, the energy output by the electrode assembly 145 acts on the target area. In the embodiment of the present application, the transformer 1422 can amplify and boost the sine wave output by the RF generating component 1421 to different voltages to meet different needs. Optionally, the transformer 1422 can amplify and boost the sine wave to 50V to 120V. Here, those skilled in the art can set the RF voltage as needed, not limited to the 50V to 120V exemplified here. It should be known that the higher the RF voltage, the greater the RF energy. In practice, considering safety, the RF voltage is set to not exceed 120V.

The present application does not limit the way in which the RF generating component 1421 converts a square wave into a sine wave, and those skilled in the art should be able to understand its implementation method based on the prior art. The RF generating component 1421 is preferably capable of outputting a sine wave with a RF frequency of 1MHz to 4MHz, so as to achieve high-frequency output. For example, in one embodiment, the RF generating component 1421 uses a GaN MOS driver chip to adjust the RF frequency to 1MHz to 4MHz, and the RF can be adjusted to a sine wave through an adaptation circuit. The GaN MOS driver chip provided by the present invention can achieve high-frequency output, and has high energy conversion efficiency, low heat generation, and low waveform distortion. Specifically, the RF generating component 1421 of the present invention can output a sine wave as shown in Figure 9 after using a GaN MOS driver chip. The higher the RF voltage, the greater the energy intensity of the RF. At the same time, considering safety, the RF voltage is controlled not to exceed 120V, that is, -60V to +60V. It can also be seen that the overall distortion of the waveform shown in Figure 9 is small, stable output is achieved, and energy conversion efficiency is high.

When the first relay 1411 is connected to the microcurrent ion introduction generating device 143, the microcurrent ion introduction generating device 143 converts the square wave signal output by the control device 13 into a pulse signal corresponding to the microcurrent and outputs it to the electrode assembly 145. The energy output by the electrode assembly 145 acts on the target area.

Preferably, in the radio frequency microcurrent working mode, the electronic device 10 has multiple gears, each of which The gear position corresponds to an output state reflecting the output information of the radio frequency microcurrent, the output states reflected by all the gear positions are different, the radio frequency current under all the output states remains constant, and the radio frequency voltage and microcurrent under different output states are different. And/or, in the electroporation ion introduction working mode, the electronic device 10 also has multiple gear positions, each of the gear positions corresponds to an output state reflecting the output information of the electroporation ion introduction, the output states reflected by all the gear positions are different, and under different output states, at least one of the pulse width, frequency, voltage of the electroporation pulse and the current intensity of the ion introduction current is different. Therefore, different intensities of output can be achieved according to the settings of different gear positions, which is more flexible and convenient to use.

In an exemplary embodiment, the input device 11 includes a plurality of buttons, and the plurality of buttons are used to receive input information to control the power-on, working mode selection, selection of different gears, and auxiliary function mode selection of the electronic device 10. The present application does not limit the specific number of buttons, which may be 2, 3 or more, preferably 3 buttons.

As shown in FIG. 1 and FIG. 3a, in one embodiment, the input device 11 includes a first button 111, a second button 112, and a third button 113, which are all arranged on the fuselage 22 and can be directly pressed or touched by the user. The first button 111 is used for power-on control, and is also used to selectively generate a type of input information corresponding to the radio frequency microcurrent working mode and the electroporation ion introduction working mode. The second button 112 is used to generate gear information corresponding to the input information after the first button 111 generates the input information, and the gear information reflects the output state of the energy output device 14. The third button 113 is used to generate input information corresponding to the auxiliary function mode, such as input information reflecting auxiliary function modes such as skin detection, ice compress cooling, etc. For example, long press the first button 111 to control the electronic device 10 to turn on and put the electronic device 10 in standby mode. Short press the first button 111 to select the working mode, and short press the first button 111 in sequence to switch different working modes. Short press the second button 112 to select the gear, and short press the second button 112 in sequence to switch different gears. Short press the third button 113 to enter the auxiliary function mode, such as skin detection mode and ice cooling mode.

In a specific embodiment, the first button 111 can generate first input information corresponding to the first working mode of the radio frequency microcurrent, second input information corresponding to the second working mode of the radio frequency microcurrent, and third input information corresponding to the electroporation ion introduction mode. The first input information is the first function, the second input information is the second function, and the third input information is the third function.

If the first button 111 is short pressed, the first function is selected, and the first function is the first working mode of radio frequency microcurrent. When the first function is selected, the first electrode assembly 1451 connects the radio frequency generator 142 and the microcurrent ion introduction generator 143. When the first electrode assembly 1451 is close to the skin, the radio frequency generator 142 outputs a radio frequency of 2MHz to 4MHz, and the microcurrent ion introduction generator 143 outputs a microcurrent of 335μA to 500μA. Optionally, under the control of the control device 13, the first relay 1411 enables the radio frequency generator 142 to output for 10s, and the microcurrent ion introduction generator 143 to output for 5s, and outputs alternately at this frequency. Optionally, in the first working mode of radio frequency microcurrent, the radio frequency generating component 1421 outputs a sine wave (radio frequency) of 2MHz to 4MHz to the transformer 1422, and the transformer 1422 amplifies the sine wave and boosts it to 90V to 110V and then outputs it to the first electrode assembly 1451.

If the first button 111 is short pressed, the second function is switched to the second working mode of the radio frequency microcurrent. When the second function is selected, the second electrode assembly 1452 connects the radio frequency generator 142 and the microcurrent ion introduction generator 143. When the second electrode assembly 1452 is close to the skin, the radio frequency generator 142 outputs a radio frequency of 1MHz to 2MHz (preferably 1MHz), and the microcurrent ion introduction generator 143 outputs a microcurrent of 335μA to 500μA (preferably 335μA). Optionally, under the control of the control device 13, the first relay 1411 enables the radio frequency generator 142 to output for 5s, and the microcurrent ion introduction generator 143 to output for 2s, and outputs alternately at this frequency. Optionally, in the second working mode of the radio frequency microcurrent, the radio frequency generating component 1421 outputs a sine wave of 1MHz to 2MHz to the transformer 1422, and the transformer 1422 amplifies the sine wave and boosts it to 40V to 60V (preferably 50V) and then outputs it to the second electrode assembly 1452. At this time, for areas with thinner epidermis, reduce the power and current to avoid skin damage. It should be understood that the RF current is constant, and different output intensities are achieved by changing the RF frequency and RF voltage.

Take three gears as an example, see Figure 20. When the first function is selected, the first gear of the first working mode of the radio frequency microcurrent is turned on by default. In the first gear, after the first electrode assembly 1451 is pressed against the skin, the radio frequency generating component 1421 outputs a sine wave of 2MHz to 4MHz to the transformer 1422, and the transformer 1422 amplifies the sine wave and boosts it to 90V. After switching to microcurrent, the microcurrent ion introduction generating device 143 outputs a microcurrent of 355μA. If the second button 112 is short pressed to turn on the second gear of the first working mode of the radio frequency microcurrent, in the second gear, the radio frequency generating component 1421 outputs a sine wave of 2MHz to 4MHz to the transformer 1422, and the transformer 1422 amplifies the sine wave and boosts it to 100V. After switching to microcurrent, the microcurrent ion introduction generating device 143 outputs a microcurrent of 425μA. If the second button 112 is short pressed to turn on the second gear of the first working mode of the radio frequency microcurrent, in the second gear, the radio frequency generating component 1421 outputs a sine wave of 2MHz to 4MHz to the transformer 1422. Press button 112 to turn on the third gear of the first working mode of the radio frequency microcurrent. In the third gear, the radio frequency generating component 1421 outputs a sine wave of 2MHz to 4MHz to the transformer 1422. The transformer 1422 amplifies the sine wave and boosts it to 110V. After switching to microcurrent, the microcurrent ion introduction generating device 143 outputs a microcurrent of 500μA.

In the output state shown in Figure 20, the RF current remains constant, and the RF frequency and microcurrent in different output states are different. In the RF microcurrent working mode, technicians in this field can set multiple different output states as needed, and should not be limited to the situation shown in Figure 20. When the RF current is constant, due to the different RF voltages, the RF output power is also different, and when switching from the first gear to the third gear in sequence, the output power gradually increases, and the heating efficiency on the skin is higher. For microcurrent, the output power also changes when switching between different gears, so that the ions under the action of microcurrent can penetrate deeply into the skin, directly reach the dermis, promote cell metabolism, and synthesize collagen.

The embodiment of the present invention also provides a control method of an electronic device, which is used to control the electronic device 10 of this embodiment, and the control method includes: the energy output device 14 determines to start the radio frequency microcurrent working mode according to the input information of the input device 11, and after starting the radio frequency microcurrent working mode, the energy output device 14 alternately outputs radio frequency and microcurrent at a specific frequency according to the received square wave signal; or, the energy output device 14 determines to start the electroporation ion introduction working mode according to the input information of the input device 11, and after starting the electroporation ion introduction working mode, the energy output device 14 alternately outputs electroporation pulses and ion introduction currents at a specific frequency according to the received square wave signal.

Referring to FIG. 10 , as an embodiment, when executing the control method, controlling the radio frequency microcurrent includes the following steps:

Step S301: receiving input information generated by the input device 11, and the control device 13 outputs a square wave signal with a fixed duty cycle according to the input information; specifically, the control device 13 outputs a square wave with a fixed duty cycle through the PWM adjustment function of the MCU (microcontroller unit);

Step S302: According to the control information of the corresponding square wave signal generated by the control device 13, the energy output device 14 outputs radio frequency and micro current alternately at a specific frequency;

Step S303: the detection device 15 obtains output information of the energy output device 14; the output information here includes radio frequency output information and micro current output information;

Step S304: The control device 13 obtains information about the energy output device 14 according to the output information of the energy output device 14. The system security result of the output state of the measurement output device 14 is obtained, and corresponding security processing measures are generated according to the system security result and the preset security policy.

As a specific embodiment, as shown in FIG11 , step S304 includes the following steps:

Step S3041: the control device 13 obtains the output value in the output information, and compares the output value with the safety threshold;

Step S3042: If the comparison result shows that the output value does not exceed the safety threshold, the power supply device 12 maintains the current voltage and continues to output the radio frequency and micro current alternately;

Step S3043: If the comparison result is that the output value exceeds the safety threshold, the power supply device 12 reduces the voltage or stops outputting.

Preferably, after starting the RF-microcurrent working mode, before alternately outputting RF and microcurrent, the control method also includes: the energy output device 14 determines a first working mode to start the RF-microcurrent working mode according to the input information; the energy output device 14 alternately outputs 2MHz-4MHz RF and 335μA-500μA microcurrent in the first working mode; or, the energy output device 14 determines a second working mode to start the RF-microcurrent working mode according to the input information; the energy output device 14 alternately outputs 1MHz-2MHz RF and 335μA-500μA microcurrent in the second working mode.

Preferably, after starting the RF-microcurrent working mode, before alternately outputting RF and microcurrent, the control method also includes: the energy output device 14 determines the current output gear according to the input information; the energy output device 14 alternately outputs RF and microcurrent under the output conditions determined by the current output gear; the output conditions include RF voltage, RF current, RF frequency and microcurrent.

Preferably, after starting the radio frequency microcurrent working mode, the radio frequency generating device 142 adjusts the square wave corresponding to the square wave signal to a radio frequency (sine wave) output with a radio frequency of 1MHz to 4MHz after receiving the square wave signal, and the microcurrent ion introduction generating device 143 adjusts the square wave corresponding to the square wave signal to a pulse output with a microcurrent of 335μA to 500μA. Therefore, when outputting radio frequency, the radio frequency is low-power and high-frequency output, which solves the problem that high heat stays in the surface layer and cannot quickly reach the connective tissue of the dermis; and when outputting microcurrent, the output value of the microcurrent is controlled at 335μA to 500μA, which promotes the production of collagen while relaxing the muscles that are damaged by excessive contraction and improving tendons. The water content and conductivity of the membrane promote metabolism.

As shown in FIG12 , in one embodiment, the microcurrent ion introduction generating device 143 includes a microcurrent ion introduction generating component 1431 and a current regulating component 1432. The microcurrent ion introduction generating component 1431 is used to directly connect the second relay 1412 or the first relay 1411. The output end of the microcurrent ion introduction generating component 1431 is connected to the current regulating component 1432, and the output end of the current regulating component 1432 is directly connected to the electrode assembly 145.

When the first relay 1411 is connected to the micro-current ion introduction generating component 1431, the micro-current ion introduction generating component 1431 receives the square wave signal output by the control device 13, and adjusts the current value to output the corresponding micro-current pulse. When the second relay 1412 is connected to the micro-current ion introduction generating component 1431, the micro-current ion introduction generating component 1431 receives the square wave signal output by the control device 13, and further outputs the PWM square wave signal to the current regulating component 1432, and the current regulating component 1432 adjusts the current density of the PWM square wave signal and outputs it to the electrode assembly 145. The current regulating component 1432 directly outputs the low-intensity constant current corresponding to the ion introduction to the electrode assembly 145 and acts on the skin.

As shown in FIG. 12 , in one embodiment, the electroporation generating device 144 includes an electroporation pulse generating component 1441 and a voltage regulating component 1442. The electroporation pulse generating component 1441 is used to be directly connected to the second relay 1412. The output end of the electroporation pulse generating component 1441 is connected to the voltage regulating component 1442, and the output end of the voltage regulating component 1442 is directly connected to the electrode assembly 145. When the second relay 1412 connects to the electroporation pulse generating component 1441, the electroporation pulse generating component 1441 receives the square wave signal output by the control device 13, and outputs the electroporation pulse (pulse bidirectional current wave), and outputs it to the voltage regulating component 1442 after adjusting the pulse width and frequency of the electroporation pulse through its own PWM. The voltage regulating component 1442 adjusts the voltage of the electroporation pulse and then outputs it to the electrode assembly 145, and acts on the skin. The voltage regulating component 1442 can output the required electroporation pulse voltage to output different electroporation pulse voltages according to actual needs. The pulse width and frequency of the pulse bidirectional current can be set according to the range that human skin can withstand.

Referring to FIG. 13 , as one embodiment, when executing the control method, controlling the electroporation ion introduction output includes the following steps:

Step S601: receiving input information generated by the input device 11, the control device 13 outputs a square wave signal with a fixed duty cycle according to the input information; specifically, the control device 13 outputs a square wave signal with a fixed duty cycle through the PWM modulation of the MCU. Switching function, outputting square wave with fixed duty cycle;

Step S602: according to the control information of the corresponding square wave signal generated by the control device 13, the energy output device 14 outputs the electroporation pulse and the ion introduction current alternately at a specific frequency;

Step S603: the detection device 15 obtains output information of the energy output device 14; the output information here includes electroporation output information and ion introduction output information;

Step S604: The control device 13 obtains a system safety result about the output state of the energy output device 14 according to the output information of the energy output device 14, and generates a corresponding safety processing measure according to the system safety result and a preset safety policy.

As a specific embodiment, as shown in FIG14 , step S604 includes the following steps:

Step S6041: the control device 13 compares the output value corresponding to the output information with the safety threshold;

Step S6042: If the comparison result shows that the output value does not exceed the safety threshold, the power supply device 12 maintains the current voltage and continues to alternately output the electroporation pulse and the iontophoresis current;

Step S6043: If the comparison result is that the output value exceeds the safety threshold, the power supply device 12 reduces the voltage or stops outputting.

In a specific embodiment, the detection device 15 acquires the output current of the ion introduction in real time and sends it to the control device 13. The control device 13 compares the output current with the safety threshold. If it is greater than the safety threshold of 500μA, the control device 13 controls the power supply device 12 to stop the output to avoid the risk of discomfort and skin damage caused by excessive current.

Preferably, after starting the electroporation ion introduction working mode, the electroporation generating device 144 adjusts the square wave of the corresponding square wave signal to an electric pulse perforation output with a voltage of 10V to 60V, a pulse width of 5ms to 20ms and a frequency of 10pps to 30pps after receiving the square wave signal, and the ion introduction generating device 143 adjusts the square wave of the corresponding square wave signal to an ion introduction current output with a current density of 100μA/ ^cm2 to 500μA/ ^cm2 . At this time, in order to promote the penetration of the effective ingredients in the skin care products, the electroporation technology is combined with the ion introduction technology, so that the electroporation pulse is applied instantaneously, and the high-voltage electric pulse electric field is applied to the lipid bilayer molecular layer such as the cell membrane to generate a reversible temporary hydrophilic electric pore, which increases the ability of molecules to pass through the skin. The ion introduction promotes more effectively the penetration of skin care products and skin moisturizing, avoiding the limitations of using the ion introduction technology alone. Specifically, when electroporation and ion introduction act alternately, the electroporation pulse The pulse applies an instantaneous high-voltage electric pulse field to the lipid bilayer of the cell membrane, generating reversible temporary hydrophilic electric channels, increasing the ability of molecules to pass through the skin, and ion introduction to promote more effective penetration of skin care products and skin moisturizing.

Further, after the electroporation ion introduction working mode is started, before the electroporation pulses and ion introduction are alternately outputted, the method further includes: the energy output device 14 determines a first working mode for starting the electroporation ion introduction working mode according to the input information; the energy output device 14 alternately outputs electroporation pulses with a voltage of 40V to 60V, a pulse width of 10ms to 20ms, and a frequency of 20pps to 30pps, and an ion introduction current with a current density of 200μA/ ^cm2 to 500μA/ ^cm2 in the first working mode; or, the energy output device 14 determines a second working mode for starting the electroporation ion introduction working mode according to the input information; the energy output device 14 alternately outputs electroporation pulses with a voltage of 10V to 20V, a pulse width of 5ms to 10ms, and a frequency of 10pps to 20pps, and an ion introduction current with a current density of 100μA/ ^cm2 to 200μA/ ^cm2 in the second working mode.

Furthermore, after starting the electroporation ion introduction working mode, before alternately outputting electroporation pulses and ion introduction, it also includes: the energy output device 14 determines the current output gear according to the input information; the energy output device 14 alternately outputs electroporation pulses and ion introduction under the output conditions determined by the current output gear; the output conditions include the voltage, pulse width and frequency of the electroporation pulse and the current density of the ion introduction.

In one embodiment, the first button 111 is short pressed to select the third function, which is the electroporation ion introduction working mode. When the third function is selected, the first electrode assembly 1451 connects the microcurrent ion introduction generator 143 and the electroporation generator 144. When in use, after the first electrode assembly 1451 is close to the skin, the electroporation pulse generating component 1441 adjusts the pulse width of 5ms to 20ms, the frequency of 10pps to 30pp, and the voltage of 10V to 60V through PWM, and the microcurrent ion introduction generator 143 outputs a constant current of 100μA/ ^cm2 to 500μA/ ^cm2 . Optionally, under the control of the control device 13, the second relay 1412 causes the electroporation generator 144 to output for 5s and the microcurrent ion introduction generator 143 to output for 10s, and the output is alternating at this frequency. It should be understood that electroporation pulses are first used to act on the skin load to achieve an instantaneous decrease in skin impedance and form micropores. Then ion introduction is used. Ion introduction, based on the principle of like charges repel each other, pushes the active ingredients in the skin care products into the dermis through the micropores, thereby promoting the absorption of the skin care products.

Take three gears as an example, as shown in Figure 21. When the third function is selected, the first gear of the electroporation ion introduction working mode is turned on by default. In the first gear, after the first electrode assembly 1451 is close to the skin, the electroporation pulse generating component 1441 adjusts the pulse width value to 10ms and the pulse frequency to 20pps through PWM and outputs a bidirectional pulse square wave to the voltage regulating component 1442. The voltage regulating component 1442 adjusts the bidirectional pulse square wave to a bidirectional pulse square wave with a voltage of 40V through the adaptation circuit and the resistor, and after switching to ion introduction, the microcurrent ion introduction generating component 1431 outputs a PWM square wave to the current regulating component 1432. The current regulating component 1432 adjusts the current intensity value of the PWM square wave to 100μA/ ^cm2 through the operational amplifier circuit. When the third function is selected, if the second button 112 is short pressed to turn on the second gear of the electroporation ion introduction working mode, in the second gear, the electroporation pulse generating component 1441 adjusts the pulse width value to 15ms and the pulse frequency to 25pps through PWM and outputs a bidirectional pulse square wave to the voltage regulating component 1442, the voltage regulating component 1442 adjusts the bidirectional pulse square wave to a bidirectional pulse wave with a voltage of 50V through the adaptation circuit and the resistor, and after switching to ion introduction, the microcurrent ion introduction generating component 1431 outputs a PWM square wave to the current regulating component 1432, and the current regulating component 1432 adjusts the current intensity value to 150μA/ ^cm2 through the operational amplifier circuit. When the third function is selected, the second button 112 is short pressed to start the third gear of the electroporation ion introduction working mode. In the third gear, the electroporation pulse generating component 1441 adjusts the pulse width value to 20ms and the pulse frequency to 30pps through PWM and outputs a bidirectional pulse square wave to the voltage regulating component 1442. The voltage regulating component 1442 adjusts the bidirectional pulse square wave to a bidirectional pulse wave with a voltage of 60V through an adaptation circuit and a resistor. After switching to ion introduction, the microcurrent ion introduction generating component 1431 outputs a PWM square wave to the current regulating component 1432. The current regulating component 1432 adjusts the current intensity value to 200μA/ ^cm2 through the operational amplifier circuit.

Therefore, by switching different gears, the output intensity of the electroporation pulse and the output intensity of the iontophoresis can be changed to meet different usage requirements. However, in the electroporation iontophoresis mode, the output state of the electronic device 10 includes but is not limited to the situation illustrated in FIG. 21. In fact, those skilled in the art can set a plurality of different output states as needed.

FIG15 shows a block diagram of the structure of an electronic device in one embodiment of the present invention. As shown in FIG15 , the electronic device 10 further includes an LED light emitting device 23, which is used to generate light waves with a wavelength of 415nm to 850nm, and the LED light is fixed on the working head 21. In a specific embodiment, the LED light emitting device 23 can emit light of a corresponding wavelength under the control of the control device 13. When the LED light emitting device 23 emits yellow light with a wavelength of 560nm to 590nm, it can help repair the epidermal barrier; when the LED light emitting device 23 emits red light with a wavelength of 620nm to 650nm, it can enhance cell activity, accelerate enzymatic reactions, promote cell metabolism, and stimulate collagen regeneration; when the LED light emitting device 23 emits near-infrared light with a wavelength of 820nm to 850nm, it can accelerate blood circulation and build a new collagen fiber network. When the LED light emitting device 23 emits blue light with a wavelength of 410nm to 430nm, it can reduce inflammation and calm the skin.

Furthermore, the electronic device 10 further includes a refrigeration device 24, which is disposed on the working head 21 and can cool the working surface of the working head 21 to realize the ice compress function of the working head 21. In a specific embodiment, the refrigeration device 24 continuously outputs a 10°C to 15°C ice sensation under the control of the control device 13, especially when used in combination with blue light, effectively alleviating the discomfort caused by radio frequency heating of the skin.

Furthermore, the electronic device 10 further includes a skin detection device 25, which is disposed in the body 22 and is used to detect skin moisture and elasticity to verify the efficacy of the electronic device 10 after use. In one embodiment, the skin detection device 25 detects skin moisture and elasticity under the control of the control device 13.

Furthermore, the electronic device 10 further includes a display device 26, which is disposed on the body 22 and is used to display the working state of the electronic device 10 (such as displaying the current working mode, output information under the current gear, etc.), and it may have a semi-transparent display window 261 (see FIG. 3 a). The display device 26 is used to display the working state of the electronic device under the control of the control device 13.

Furthermore, the electronic device 10 further includes a sound prompt device 27, which is disposed on the body 22 and serves as an operation prompt feedback of the electronic device 10. For example, when the electrode contacts the skin to output energy, a sound can be emitted, such as vibration. The sound prompt device 27 emits a sound prompt under the control of the control device 13.

As shown in Figures 3a and 4, further, the electronic device 10 also includes a portable charging base 28, which can be used as a charging base and as a protective cover for the working head 21. As shown in Figure 3a, when not in use, the charging base 28 is covered on the working head 21 to protect the working head 21. As shown in Figure 1, when in use, the charging base 28 on the working head 21 is removed, and the working head 21 can be used normally. As shown in Figure 15, the charging base 28 preferably includes a charging component 281 and a sterilization component 282. The charging component 281 is used to charge the battery 121 in the power supply device 12, and the sterilization component 282 is used to sterilize and disinfect the working head 21 and the electrode assembly 145, preferably UVC disinfection. Furthermore, after the second electrode assembly 1452 is turned off, it can be inserted into the charging base 28 and contact with the charging component 281 to be used as a charging electrode. That is, after the second electrode assembly 1452 is used, the working head 21 is inserted into the charging base 28. At this time, the two electrode sheets in the second electrode assembly 1452 can be used as charging electrodes to charge the electronic device 10.

As shown in FIG. 22 , in a preferred embodiment, the control device 13 includes a microcontroller unit (MCU) 131, and the microcontroller unit 131 controls the first relay 1411 to selectively connect to one of the radio frequency generating circuit and the microcurrent generating circuit. The radio frequency generating circuit is represented by RF+ and RF-, and the microcurrent generating circuit is represented by MC+ and MC-. When the radio frequency is output, the radio frequency generating circuit RF+ and RF- connect to the electrode assembly 145, and when the microcurrent is output, the two microcurrent generating circuits MC+ and MC- connect to the electrode assembly 145. Therefore, the microcontroller unit 131 controls the switching frequency and timing of the first relay 1411. Since the two energies are output alternately, temperature monitoring and current detection must also be monitored simultaneously, and the electronic device 10 also needs to match the corresponding control and safety logic design according to the output requirements.

As shown in FIG. 23 , in a preferred embodiment, the microcontroller unit 131 controls the second relay 1412 to selectively connect to one of the electroporation generating circuit and the ion introduction generating circuit, and the microcontroller unit 131 controls the switching frequency and timing of the second relay 1412.

When the electroporation pulse is output, the electroporation generating circuit EP+ and EP- connect to the electrode assembly 145, and when the ion introduction current is output, the ion introduction generating circuit ION+ and ION- connect to the electrode assembly 145.

Next, experimental data is used to further demonstrate the technical effects that can be achieved by the present invention.

Figure 16 shows the skin elasticity improvement effect achieved by the product of the present invention and the comparative example product, wherein 2W represents 2 weeks of use, 4W represents 4 weeks of use, and the ordinate represents the skin elasticity R2 value; the height of the bar graph represents the test result, and the test result represents the skin elasticity data compared with the skin elasticity base value of 0.

As shown in Figure 16, after using 2W, when only radio frequency is used, the skin elasticity change rate R2 is 1.1%, when radio frequency and microcurrent are used independently, the skin elasticity change rate R2 is 3.2%, and when radio frequency and microcurrent are used alternately and synergistically, the skin elasticity change rate R2 is 3.4%; after using 4W, when only radio frequency is used, the skin elasticity change rate R2 is 9.3%, when radio frequency and microcurrent are used separately, the skin elasticity change rate R2 is 10.3%, and when radio frequency and microcurrent are used alternately and synergistically, the skin elasticity change rate R2 is 13.8%. The larger the skin elasticity change rate R2 value, the more obvious the improvement of skin elasticity. It can be seen that when radio frequency and microcurrent act alternately and synergistically, the treatment effect on the skin is better, and the skin elasticity is significantly improved.

Figure 17 shows the efficacy of improving skin roughness achieved by the products of the present invention and the comparative example products. The skin roughness is tested using the reduction in pore area, where 2W represents 2 weeks of use, and 4W represents 4 weeks of use. The ordinate is the rate of change of total pore area. The height of the bar graph is the test result. By comparing the total pore area base value of 0, the rate of change of total pore area can be obtained. Since the total pore area is reduced compared to the base value, the rate of change of total pore area is a negative value.

As shown in Figure 17, after using 2W, when only radio frequency was used, the total pore area changed by -10.6%, when radio frequency and micro current were used separately, the total pore area changed by -3.8%, and when radio frequency and micro current were used alternately and synergistically, the total pore area changed by -6.5%; after using 4W, when only radio frequency was used, the total pore area changed by -0.4%, when radio frequency and micro current were used separately, the total pore area changed by -16.7%, and when radio frequency and micro current were used alternately and synergistically, the total pore area changed by -35.3%. The greater the total pore area change rate, the more obvious the improvement in skin roughness. Therefore, when radio frequency and micro current are used alternately and synergistically, the treatment effect on the skin is better, and the skin roughness is also significantly improved.

Table 1 below shows the test data of the immediate effect of using the penetration-enhancing function of the product of the present invention and the direct application of skin care products in the comparative example. According to the data in Table 1, after using the penetration-enhancing function of the electroporation ion introduction of the present invention, the moisture enhancement, oil replenishment and roughness are significantly improved, all of which have a trend higher than directly applying skin care products, and the enhancement effect is statistically significant. Among them, in the electroporation ion introduction function, it is used once for 4 minutes, and the data in Table 1 are the immediate effects after one-time use.

Table 1: Test data of the immediate effect of directly applying skin care products using the penetration-enhancing function of the present invention and the comparative examples

Note: The data in Table 1 are statistically significant compared with the baseline values, and in Table 1, *P<0.05,
**P<0.01, ***P<0.001.

Referring to Figure 18, the left micrograph shows the skin condition around the eyes when skin care products are used alone, and the right micrograph shows the skin condition around the eyes when ion introduction skin care products are used alone. Comparing the area circled by the dotted line a in the right micrograph in Figure 18 and the area circled by the dotted line b in the left micrograph, it can be seen that when the ion introduction function is used alone, the absorption rate of the effective ingredients in the skin care products by the skin is extremely low, and the moisturizing and roughness improvement efficiency of the skin around the eyes are not ideal.

Referring to Figure 19, the left micrograph shows the skin condition around the eyes when skin care products are used alone, and the right micrograph shows the skin condition around the eyes when skin care products are promoted by electroporation ion introduction. Comparing the area circled by the dotted line c in the right micrograph of Figure 19 with the area circled by the dotted line d in the left micrograph, it can be seen that the combined use of electroporation ion introduction greatly improves the absorption rate of the effective ingredients in the skin care products by the skin, and the moisturizing and roughness of the skin around the eyes are significantly improved.

It should be understood that the technical concept of the electronic device 10 of the present invention integrating four energy outputs is based on efficacy. The combined application of radio frequency and microcurrent can directly produce a lifting and firming effect on the skin and achieve better therapeutic effects; while electroporation and ion introduction themselves do not have a firming effect on the skin, but can promote its absorption when used with lifting and firming skin care products, achieving twice the result with half the effort. In addition to the combined application of the two technologies, it is also considered that the skin of different parts of the face needs to match different energy intensities. Therefore, the electronic device 10 of the present invention can have multiple working modes to output different energy intensities to achieve a safe and effective purpose.

Furthermore, when the electronic device 10 of the present invention is used as a handheld portable beauty device, integrating radio frequency, microcurrent, electroporation and ion introduction functions in the limited space of the electronic device 10 puts forward higher requirements for the design of the circuit and structure, which are specifically reflected in the following aspects:

(1) Due to the limited space of the electronic device 10, the entire hardware design (corresponding to the structural design) must take into account the generation device that can be shared (such as ion introduction and microcurrent output), adjust the energy form of the final output through the back-end matching circuit, and share the electrode assembly, which has high requirements for hardware design and logic;

(2) Outputting different energies for different target areas also places requirements on hardware design and structure. Traditional RF beauty devices can only output one RF frequency, most of which are 1 MHz. However, it is difficult to achieve stable high frequency (such as above 3MHz) and high power conversion rate; the electronic device 10 of the present invention can output a frequency in the range of 1MHz to 4MHz, and can be accurately applied to the face and thinner skin around the eyes in combination with electrodes of different sizes and locations.
