[0043] Example 1

[0044] Please refer to the reference. Figures 1 to 4 This utility model embodiment provides an electrode head 2 for use in a beauty device. The electrode head 2 is disposed 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 components 22, which are, from the inside to the outside, a central electrode group 221, an intermediate electrode group 222, and an outer electrode group 223. The multi-layer structure of the electrode group is used to achieve a variety of beauty effects.

[0045] It can be understood that the aforementioned substrate 21 is the part of the beauty device that comes into direct contact with the skin, and is used to provide an installation base and structural support for the electrode assembly 22.

[0046] Specifically, the central electrode group 221 is located at the geometric center of the substrate 21; the intermediate electrode group 222 and the outer electrode group 223 surround its outer periphery in sequence, and at least one of them is composed of multiple discrete electrodes arranged in the same shape and outline, and at least one of them is a closed electrode group.

[0047] 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.

[0048] 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.

[0049] In this embodiment, the arrangement of the multilayer electrodes has the same outline, which makes the distance between adjacent electrode groups more balanced, thereby forming a more balanced electric field between adjacent electrode groups, so as to achieve uniform stimulation of the skin.

[0050] 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.

[0051] Please refer to Figure 2 This is a schematic diagram of one type of electrode head in this embodiment. The intermediate electrode group 222 is a single set and has a closed ring structure, while the outer electrode group 223 is a single set and is composed of multiple discrete electrodes.

[0052] 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 specified 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.

[0053] At least one intermediate electrode group 222 also consists of multiple second discrete electrodes, which are arranged along a specified contour with the central electrode group 221 as the center, and adjacent second discrete electrodes are arranged at intervals.

[0054] 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.

[0055] 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.

[0056] It should be explained that the substrate 21, as the part of the beauty device that directly contacts the skin, has a contour referring to the shape of its outer edge. When the substrate is polygonal, such as a quadrilateral or hexagon, its contour is the shape formed by the sides of the polygon. In the design of the electrode head, the middle electrode group 222 and the outer electrode group 223 are arranged along the contour of the substrate. This design allows the electrodes to better conform to different parts of the human skin. For example, when used on the face, it conforms to the curves of the face, ensuring full contact between the electrodes and the skin, making the current action more effective, and thus enhancing the beauty effect.

[0057] Please refer to Figure 3 This is a schematic diagram of another electrode head in this embodiment. The intermediate electrode group 222 and the outer electrode group 223 are both groups, each composed of multiple discrete electrodes.

[0058] Furthermore, the central electrode group 221 is composed of an electrode block, and the first discrete electrode and the second discrete electrode are identical in shape and size to the electrode block, thereby ensuring the uniformity of the electric field.

[0059] It is understood that in various embodiments, when the substrate 21 is polygonal, it is an electrode group composed of multiple discrete electrodes.

[0060] Optionally, in an electrode group consisting of multiple discrete electrodes, the positions of each discrete electrode are aligned with the midpoint of each side of the substrate 21 and / or the corner of the substrate 21.

[0061] Wherein, when each discrete electrode is uniformly distributed at the midpoint of each side of the substrate 21, such as Figure 2 As shown; when each discrete electrode is uniformly distributed at the midpoint of each side of the substrate 21, and further distributed at the corners of the substrate 21, as... Figure 4 As shown, this setup can largely maintain a relatively balanced distance between the discrete electrodes and the closed-loop electrodes, thereby maintaining a relatively balanced electric field line between them, which can further optimize the distribution of current on the skin surface.

[0062] It is understood that polygons include, but are not limited to, quadrilaterals, hexagons, etc. The design of polygons is conducive to the rational layout of electrode components 22 within a limited space, and different polygon shapes can be adapted to the contour characteristics of different parts of the human body such as the face and neck. For example, a quadrilateral base 21 may be more suitable for the flat area of ​​the face, while a hexagon is more advantageous when conforming to the curve of the neck, thereby improving the contact effect between the electrode head 2 and the skin and enhancing the cosmetic effect.

[0063] Furthermore, in this embodiment, the outer electrode group 223, the intermediate electrode group 222, and the center electrode work together to output at least one of electroporation, EMS, or iontophoresis current. Alternatively, the outer electrode group 223, the intermediate electrode group 222, and the center electrode are used to output an AC waveform higher than 2.5 kHz and lower than 3.5 kHz under their synergistic effect.

[0064] In practical applications, such as to promote the penetration of beauty serums, electroporation current can be output. The waveform of the electroporation current is as follows: Figure 5 As shown.

[0065] In some real-time modes, the electrode head 2 provided in this embodiment operates at a frequency of 55.56 Hz, that is, the pulse period output by the electrode head is 18 ms, of which 400 μs outputs an electroporation waveform. This operating frequency setting allows the pulse signal output by the electrode to act on the skin at specific time intervals, ensuring effective stimulation of the skin for a certain duration while avoiding excessive stimulation that could cause discomfort.

[0066] In this embodiment, the electroporation frequency is 2.5 kHz, the electroporation pulse width is 190 μs, and the electroporation delay is 20 μs. It is understood that appropriate pulse width and frequency ensure the safety and effectiveness of the electroporation current, while appropriate delay reduces waveform abrupt changes and ensures the stability of the electroporation current. This allows a stable electroporation current to quickly form microchannels on the skin, enabling nutrients such as beauty serums to penetrate deeper into the skin more efficiently. Understandably, the electroporation frequency is selected within the range of 2.5kHz-3.5kHz. When the discharge frequency of the electrode component 22 is less than 2.5kHz, the discharge energy may be insufficient, failing to form a skin channel penetrating the skin surface and affecting the absorption effect. Conversely, when the discharge frequency of the electrode component 22 is greater than 3.5kHz, the discharge energy may be too high, leading to skin redness, allergies, and other phenomena. Therefore, limiting the discharge frequency of the electrode component 22 to between 2.5kHz and 3.5kHz allows for better deep skincare efficacy while further protecting the skin and optimizing the user experience.

[0067] 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.

[0068] In addition, the voltage range of electrode head 2 is 11~15V. Within this voltage range, the electrode can ensure the intensity of action and output a suitable current to achieve the beauty effect.

[0069] In another embodiment, when the outer electrode group 223, the middle electrode group 222 and the central electrode work together, the current output mode is a diversified nursing plan, which is conducive to realizing personalized adjustments for different users.

[0070] Specifically, when the electrode assembly simultaneously outputs electroporation, EMS, and iontophoresis currents, a comprehensive skincare effect can be achieved. The EMS current stimulates blood circulation and muscle contraction in the skin, not only enhancing skin activity and increasing nutrient penetration but also improving skin elasticity and reducing sagging. The electroporation current rapidly forms microchannels on the skin surface, allowing nutrients to penetrate more easily into the deeper layers. The iontophoresis current, utilizing the channels created by electroporation, more efficiently delivers nutrient-rich ingredients into the deeper layers of the skin, achieving a comprehensive skincare effect that tightens the skin and promotes absorption.

[0071] When the electrode assembly outputs electroporation, EMS, and iontophoresis currents at different times, the order can be adjusted according to actual needs. For example, for daily basic skincare, the iontophoresis current is activated first to help the skin absorb nutrients from daily skincare products and replenish the skin's energy; during periodic firming treatments, the EMS current is output alone to stimulate muscle movement and improve skin firmness; and when intensive care is needed, the electroporation current is used first to open the skin channels, and then the iontophoresis current is switched to enhance the penetration of nutrients and achieve a highly targeted treatment. By flexibly selecting different output modes at different times, the beauty needs of users in different scenarios can be met.

[0072] It is understood that, in this embodiment, the frequency of the electroporation current can be selected in the range of 2.5KHz-3.5KHz, while the frequency of the EMS current can be selected in the range of 12.5Hz-125Hz.

[0073] Furthermore, the spacing between each electrode group is set to 2mm, which ensures that an effective electric field is formed between the electrodes, so that the current is evenly distributed on the skin surface, while avoiding the current being too concentrated due to too small a spacing, or the electric field uniformity being affected by too large a spacing.

[0074] In each electrode group, the ratio of positive to negative electrode area is 14:9, thereby optimizing the electric field distribution between the electrodes. By rationally adjusting the areas of the positive and negative electrodes, the effect of the current on various parts of the skin is made more balanced. Larger electrodes can cover a wider area of ​​the skin, while the appropriate area ratio ensures a balanced distribution of electric field intensity on the skin surface, avoiding localized areas of excessively strong or weak current, thus achieving uniform stimulation of the skin.

[0075] Example 2

[0076] Please refer to Figure 6 Based on the foregoing embodiments, this utility model also provides a beauty device, which mainly includes a handle 1 and electrode heads 2. The handle 1 adopts an ergonomic design to ensure comfortable grip and stable operation for the user.

[0077] Electrode head 2 is an electrode head 2 used in beauty devices as described in any of the preceding items.

[0078] 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.

[0079] 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.

[0080] Example location:

[0081] 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.

[0082] 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.

[0083] When using the beauty device, in the hydration mode, the user first attaches the microneedle treatment head 3. The microneedle chips stimulate the skin while the device is applied, creating microchannels in the stratum corneum. The serum can then penetrate these microchannels, providing initial skin nourishment. After the hydration mode, the user replaces the microneedle treatment head 3 with the electrode attachment and installs it on the device. Switching to the iontophoresis mode, the electroporation waveform output from electrode head 2 creates additional skin channels, further promoting serum penetration and enhancing nutrient absorption for a more ideal beauty effect. Users can also choose the EMS mode to stimulate muscle contraction or the iontophoresis mode to help nutrients be better absorbed by the skin, meeting diverse beauty needs.

[0084] Compared with the prior art, the present invention has the following beneficial effects:

[0085] The electrode head and beauty device provided by this utility model, through the setting of a multi-layered electrode assembly, wherein at least one layer is composed of multiple discrete electrodes, can more comprehensively and deeply stimulate skin cells, promote skin metabolism, and enhance beauty effects compared to traditional single or simply distributed electrodes.

[0086] 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.
