For those skilled in the art to which this application pertains, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0040] This utility model provides an electrode head for use in a beauty device, which aims to stabilize the generation of electroporation waveform sequences by reasonably setting the conduction period ratio of each electroporation pulse sequence within the beauty cycle, thereby effectively improving the electroporation effect and enhancing the skin's absorption efficiency of nutrients.

[0041] Please refer to the reference. Figure 1 and Figure 2 The electrode head 2 is located at the front end of the handle 1 of the beauty device and includes a base 21. The surface of the base 21 is distributed with at least three layers of electrode assemblies 22, which are, from the inside out, a central electrode group 221, an intermediate electrode group 222, and an outer electrode group 223. The multi-layered structure of the electrode assembly forms the basis for achieving various beauty effects.

[0042] It can be understood that the portion of the aforementioned substrate 21 that comes into direct contact with the skin to be treated serves as a mounting base and structural support for the electrode assembly 22.

[0043] In one embodiment, at least one intermediate electrode group 222 may be in the form of a closed ring structure, and the polarity of the closed electrode group adjacent to the central electrode group 221 is opposite to that of the central electrode group 221; or, in the closed intermediate electrode group 222, the polarities of two adjacent groups are opposite. The aforementioned polarity settings optimize the electric field distribution. For example, pairing the polarities of the closed electrode groups can create a relatively uniform electric field, resulting in a more balanced skin care effect. Furthermore, it can optimize the area and depth of action. For instance, the closed ring structure compensates for the small area of ​​action of discrete electrodes and supplements the action on the middle and superficial layers of the skin, thus comprehensively improving the care effect.

[0044] Please refer to Figure 2 There is only one set of intermediate electrode group 222, which is a closed ring structure, while there is only one set of outer electrode group 223, which is composed of multiple discrete electrodes.

[0045] In another embodiment, the outer electrode group 223 consists of a plurality of first discrete electrodes arranged around the central electrode group 221 along a specific contour (such as the contour of the substrate 21 or the outer contour of the central electrode group 221), with adjacent first discrete electrodes spaced apart.

[0046] At least one intermediate electrode group 222 also consists of multiple second discrete electrodes, which are arranged along a specific contour with the central electrode group 221 as the center, and adjacent second discrete electrodes are arranged at intervals.

[0047] Furthermore, in the same layer of electrode group, the polarities of adjacent discrete electrodes are opposite; or, the polarities of two adjacent layers of electrode groups are opposite.

[0048] An electrode group is formed by arranging multiple discrete electrodes, which allows for flexible changes in the electric field distribution by adjusting the position and parameters of the discrete electrodes, thereby meeting the requirements of electric field strength and range for different working scenarios.

[0049] In this embodiment, the multi-layered electrode layout ensures a balanced stimulation of the skin while maximizing the area of ​​skin affected by the electrode head 2. The combination of discrete and closed electrodes provides multi-depth stimulation while achieving uniform stimulation over a larger area at the same skin depth, thus comprehensively enhancing the treatment effect. Furthermore, the closed electrode group provides a gentler, more uniform stimulation, mitigating some of the stimulation from the discrete electrode group. This prevents the overall stimulation from being too abrupt, allowing the user to experience a layered stimulation and improving the overall experience.

[0050] The aforementioned "identical arrangement outlines" refers to the similarity in the external outlines of the intermediate electrode group 222 and the outer electrode group 223 when they are arranged around the central electrode group 221. From a geometric perspective, if the distribution boundaries of the intermediate electrode group 222 and the outer electrode group 223 are drawn with lines, these two outlines are identical in shape, differing only in size. It can be understood that the outline size of the outer electrode group 223 is larger than that of the intermediate electrode group 222.

[0051] Furthermore, the identical arrangement of the multilayer electrodes allows for a more balanced distance between adjacent electrode groups, resulting in a more balanced electric field between adjacent electrode groups, thus achieving uniform stimulation of the skin.

[0052] It is understood that the above-described structural limitations of electrode head 2 are only one optional implementation method. In practical applications, other electrode head structures can also be used, all of which are within the protection scope of this utility model.

[0053] Please refer to Figure 3 In this embodiment, the electrode head 2 includes a first electrode, a second electrode, and a control module 24.

[0054] The control module 24, as the core control component of the electrode head 2, is configured to drive the first and second electrodes to output periodic alternating current signals during the beauty cycle. These signals contain at least one electroporation waveform sequence.

[0055] It is understood that the first electrode includes the aforementioned central electrode group 221, a portion of the intermediate electrode group 222, and / or a portion of the outer electrode group 223, while the second electrode includes the remaining portion of the intermediate electrode group 222 and / or a portion of the outer electrode group 223. When the control module 24 drives the first and second electrodes to output periodic alternating current signals, an alternating electric field is formed between the central electrode group 221, the intermediate electrode group 222, and the outer electrode group 223, which can achieve multiple stimulation of the skin and improvement of local circulation.

[0056] The waveform of the electroporation current is as follows Figure 4 As shown.

[0057] Specifically, each electroporation pulse sequence includes a conduction period that generates the electroporation current, and a delay protection period between the conduction periods.

[0058] The conduction period accounts for 40%-55% of the duration of a single electroporation pulse sequence.

[0059] In this embodiment, the aforementioned settings ensure that the electroporation current can effectively act on the skin, promoting the formation of microchannels on the skin surface to facilitate the absorption of nutrients; and also provide appropriate buffering during the delayed protection period to reduce the stimulation of the skin caused by the spikes formed in the electroporation pulse waveform, thereby increasing the comfort of electrical stimulation.

[0060] In practice, during the conduction period, the control module 24 applies voltage to the first and second electrodes, causing a current path to be formed between them, thereby generating electroporation current. During the delay protection period, the control module 24 stops outputting, so that the current between the first and second electrodes is disconnected, reducing peak stimulation and increasing comfort.

[0061] In one embodiment, the period of each electroporation pulse sequence is 400 μs, with a conduction period of 360-390 μs and a delay protection period of 10-40 μs. That is, the electroporation pulse width ranges from 180-195 μs. The 10-40 μs electroporation delay can be set after one electroporation pulse, or a delay of 5-20 μs can be set before and after each electroporation pulse. Of course, the delays before and after an electroporation pulse can also be set differently, as long as the total delay is 10-40 μs. With these parameter settings, the electroporation current can form a sufficient number of microchannels of appropriate depth on the skin without causing irreversible damage, achieving a good balance between therapeutic effect and safety.

[0062] In this embodiment, the distance between the first electrode and the second electrode is set within the range of 1-4 mm, and the effective working area ratio of the first electrode and the second electrode is 14:9. A reasonable electrode spacing and area ratio helps to form a uniform and stable electric field, ensuring that the electroporation current can act evenly on the skin surface, thus improving the stability and consistency of the treatment effect.

[0063] In one embodiment of this invention, the distance between the first electrode and the second electrode is set to 1 mm, and the effective working area ratio of the first electrode to the second electrode is 14:9. When the electrode distance is small, the electric field lines between the two electrodes are more densely distributed, allowing the electroporation current to act more concentratedly on the skin surface. In addition, the relatively high electric field strength enables the electroporation current to form relatively fine microchannels on the skin surface. Based on this, nutrients such as beauty serums can quickly and deeply penetrate into the intercellular spaces of the skin, making it suitable for skincare scenarios requiring rapid improvement of dry and dehydrated skin.

[0064] In another embodiment of this invention, the distance between the first electrode and the second electrode is set to 2.5 mm, and the effective working area ratio of the first electrode to the second electrode is 14:9. In this case, the distribution of the electric field lines is relatively uniform, and the effect of the electroporation current on the skin surface is more balanced. The stimulation received by the skin is relatively gentle, and the formed microchannels are of moderate size and evenly distributed. This setup promotes the absorption of nutrients and effectively promotes skin cell metabolism, making it suitable for the need to steadily improve skin texture over long-term use. Through continuous and gentle stimulation, it gradually improves the health of the skin.

[0065] In another embodiment of this invention, the distance between the first electrode and the second electrode is set to 4 mm, while maintaining the 14:9 ratio of their effective working areas. The larger electrode spacing allows for a wider electric field distribution, enabling the electroporation current to cover a larger area of ​​skin. Although the electric field strength is relatively reduced, the effect is gentler, providing uniform stimulation to the skin over a larger area, promoting blood circulation, and is suitable for soothing sensitive skin, reducing inflammation, promoting skin self-repair and regulation, and achieving a comprehensive improvement in skin condition.

[0066] In this embodiment, the duration of the beauty cycle is set to 18ms, corresponding to a base frequency of 55.56Hz. This setting ensures that the pulse signal output by the electrode head 2 acts on the skin at specific time intervals, guaranteeing effective stimulation duration while avoiding skin discomfort or poor treatment results caused by excessively high or low frequencies.

[0067] Furthermore, the electroporation waveform sequence consists of multiple pulse units, corresponding to an electroporation frequency of 2.5-3.5 kHz. Under these parameter settings, when the electroporation waveform sequence is applied to the skin, each pulse unit forms nanoscale microchannels on the cell membrane, and the synergistic effect of multiple pulse units effectively increases the number and area of ​​channels.

[0068] At the same time, the 2.5-3.5kHz frequency can effectively regulate the opening time and closing speed of the channels, ensuring that nutrients such as beauty serums can smoothly enter the cells. After completing the substance transport, these microchannels quickly return to their original state, without causing permanent damage to the cells, thus providing sufficient nutritional support to the skin and improving skin condition from the root.

[0069] Within this frequency range, the electroporation current can effectively penetrate the skin's surface, opening skin channels and promoting the penetration of nutrients such as beauty serums, without overburdening the skin. When the discharge frequency of the electrode component 22 is less than 2.5 kHz, the discharge energy may be insufficient to form skin channels penetrating the skin's surface, affecting absorption. Conversely, when the discharge frequency of the electrode component 22 is greater than 3.5 kHz, the discharge energy may be too high, leading to redness, allergies, and other skin reactions. Therefore, limiting the discharge frequency of the electrode component 22 to between 2.5 kHz and 3.5 kHz allows for better deep skincare efficacy while further protecting the skin and optimizing the user experience.

[0070] For example, the discharge frequency of the electrode assembly 22 can be specifically set to 2.5 kHz, 2.6 kHz, 2.7 kHz, 2.8 kHz, 2.9 kHz, 3.0 kHz, 3.1 kHz, 3.2 kHz, 3.3 kHz, 3.4 kHz, or 3.5 kHz. Alternatively, the range of the discharge frequency can be set between any two of the above parameter values. In actual settings, the frequency can be selected based on factors such as the age, gender, and skin type of the user group. This embodiment does not limit the specific parameters of the discharge rate.

[0071] Furthermore, the electrode head 2 provided in this embodiment also includes a voltage adjustment unit 25, which outputs a voltage range of 11-15V. Within this voltage range, the electrode can output a current of appropriate intensity to ensure that the electroporation current has sufficient energy to obtain the desired cosmetic effect, while avoiding damage to the skin due to excessive voltage.

[0072] Please refer to Figure 5 Based on the foregoing embodiments, this embodiment provides a beauty device, including the electrode head 2 applied to the beauty device as described above.

[0073] This beauty device mainly consists of a handle 1 and electrode heads 2. The handle 1 adopts an ergonomic design to ensure a comfortable grip and stable operation for the user.

[0074] Electrode head 2 is the electrode head 2 used in beauty devices as described in any of the above items.

[0075] Optionally, the electrode head 2 used in the beauty device is detachably connected to the handle 1 of the beauty device, which allows users to flexibly change different types of electrode heads 2 according to different beauty needs. For example, a specific electrode head 2 can be used when performing facial care, while a suitable electrode head 2 can be used when caring for the neck or other parts of the body, which greatly expands the application scenarios of the beauty device and improves the beauty effect.

[0076] Understandably, in order to enable the detachment and connection of the electrode head 2 and the handle 1 of the beauty device, the handle of the beauty device is provided with a mounting part for detaching and attaching the electrode head 2.

[0077] In some embodiments, the beauty device includes a microneedle treatment head 3 in addition to the beauty device handle 1 and the electrode head 2. When the electrode head 2 and the microneedle treatment head 3 are disassembled and replaced, in order to make full use of the structural space of the beauty device handle 1, the end face of the beauty device handle 1 has a positioning notch 11, and the microneedle treatment head 3 and the electrode head 2 are respectively provided with positioning protrusions 23.

[0078] It is understandable that the positioning protrusions 23 on the microneedle treatment head 3 and the electrode head 2 are the same in size and outline, and the positioning recess 11 and the positioning protrusion 23 are compatible with each other. The positioning recess 11 and the positioning protrusion 23 are interlocked and matched. When the positioning protrusion 23 is inserted into the positioning recess 11, the beauty device handle 1 and the microneedle treatment head 3, or the beauty device handle 1 and the electrode head 2 are initially positioned.

[0079] Specifically, the electrode head includes a first electrode, a second electrode, a control module 24, and a voltage regulation unit 25. Through the coordinated operation of these components, a periodic electrical signal containing an electroporation waveform sequence can be output within an 18ms cosmetic cycle.

[0080] The electroporation waveform sequence consists of multiple pulse units, with a frequency maintained at 2.5-3.5kHz. The electrode spacing is set to 1-4mm, the effective working area ratio of the first and second electrodes is 14:9, and the voltage adjustment range is 11-15V.

[0081] Based on the aforementioned parameter combination, it can promote the absorption of nutrients, enhance skin firmness, improve skin metabolism, and relieve skin inflammation during the beauty cycle.

[0082] In practical use, this beauty device is safe and efficient. It can flexibly adjust parameters such as the electroporation waveform sequence according to the skin type, age and other characteristics of different users to achieve personalized and precise skin care services, providing users with safe and efficient skin care services.

[0083] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
