Description

Technical Field

[0001] The utility model relates to the technical field of nursing equipment, in particular to a skin care device. Background Art

[0002] Skin care devices, such as photobeauty devices, utilize specific wavelengths of light and electrical energy for skin care. Sapphire, as an optical material, possesses high light transmittance and high-temperature resistance, effectively conducting the light from the light source. The electrodes transfer the electrical energy to the skin's surface, where it works in conjunction with the light energy to achieve a cosmetic effect.

[0003] In the related art, a round sapphire is typically designed on the head of the device for light to pass through and output. However, this related art still has the following shortcomings: the irrational distribution of the sapphire and electrodes can easily cause visual fatigue and poor visual appearance. Furthermore, the simple round shape cannot match the specific contours of the device head. When covering irregular or complex areas, this results in some wasted space, making it impossible to evenly distribute the sapphire and electrodes across every area of ​​the device head, resulting in an insufficient total effective working area.

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the schemes in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0038] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element.

[0039] In addition, the descriptions of "first," "second," etc. in this utility model are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0040] Skin care can be achieved by combining light energy of specific wavelengths with electrical energy (such as radiofrequency current and / or microcurrent). Specifically, light energy, especially light of specific wavelengths, such as light from 600nm to 1940nm, can penetrate the surface of the skin, penetrate deep into the dermis, activate the mitochondria in skin cells, and promote cell metabolism and collagen production. This process is called photobiomodulation, which stimulates skin cells through light, enhances cell vitality, accelerates the repair of damaged tissue, and reduces inflammatory responses. Light of specific wavelengths also has antibacterial, anti-inflammatory, and skin-improving effects, which can significantly improve problems such as acne, pigmentation, and sagging skin.

[0041] Electrical energy, particularly microcurrent and radiofrequency current, acts on the skin through electrodes, mimicking the body's bioelectrical currents and gently stimulating skin cells. This stimulation boosts blood circulation deep within the skin, accelerating metabolism and enhancing skin firmness and elasticity. Radiofrequency current, by generating a deep thermal effect, can tighten the skin, reduce wrinkles, and promote collagen reconstruction.

[0042] When light and electrical energy are applied simultaneously to the skin, they create a synergistic effect, further enhancing the effectiveness of treatments. Light stimulates cellular activity and promotes the formation of new tissue, while electrical energy enhances the skin's repair and firming functions through deep stimulation and thermal effects. This combination of energy effectively improves skin condition and provides a more comprehensive treatment experience, particularly effective in reducing fine lines, enhancing facial contours, and improving skin tone.

[0043] In order to effectively conduct the light emitted by the light emitting device and transfer the light energy from the light source to the skin surface, a light-transmitting member (sapphire) needs to be set on the working head for light guidance. The output of microcurrent and radiofrequency current requires the design of multiple electrodes on the working head. If the distribution of the electrodes and the light-transmitting member is not reasonable, the total effective working area of ​​the light-transmitting member and the electrodes will be reduced. Therefore, in this embodiment, the distribution of the light-transmitting member and the multiple electrodes is improved. For details, please refer to Figures 1 to 3 , Figure 1 This is a schematic diagram of the overall structure of a skin care device in one embodiment of the present invention. Figure 2 This is a schematic diagram of the skin care device of the utility model. Figure 3 for Figure 2 Cross-section view at AA in the middle.

[0044] The present invention provides a skin care device 10, which includes:

[0045] A housing 100 is provided with a working head 102 for acting on the skin at one end thereof, and the working head 102 is provided with an opening;

[0046] The light-transmitting member 200 has a light-emitting end surface 200 a located in the opening. The light-emitting end surface 200 a is polygonal and has more than four sides.

[0047] The light emitting device 300 is disposed in the housing 100 and emits light toward the light-transmitting member 200 to provide skin care through the light-transmitting member 200;

[0048] The plurality of electrodes 400 are at least partially exposed from the working head 102 for outputting microcurrent and / or radiofrequency current to the skin. The plurality of electrodes 400 are spaced apart and distributed around the periphery of the light-transmitting element 200 .

[0049] In this embodiment, the housing 100 of the skin care device 10 is primarily intended for user gripping and provides a mounting location for other components. A working head 102 for applying pressure to the skin is formed at one end of the housing 100. The working head 102 also has an opening for mounting a light-transmitting member 200 (also known as a light outlet, through which light emitted by the light-emitting device 300 passes). To facilitate gripping, the housing 100 can be designed with an ergonomic shape, such as a streamlined design or a handle with a non-slip design, to enhance grip comfort and stability.

[0050] The material of the housing 100 can be selected based on different needs. For example, to reduce the overall weight, a lightweight, high-strength material such as carbon fiber or aluminum alloy can be used. Considering the user's comfort when holding, the surface of the housing 100 can be made of a soft-touch material such as silicone or polyurethane coating. These materials not only provide a soft touch, but also can increase the anti-slip effect through surface treatment processes (such as spraying, plating, or rubber coating), thereby improving the user experience of the device.

[0051] The light-transmitting element 200 is mounted within the opening of the working head 102. Specifically, its light-emitting end face 200a is located within the opening and has a polygonal design with at least four sides. The main function of the light-transmitting element 200 is to guide light, ensuring that the light generated by the light-emitting device 300 is evenly and effectively transmitted to the skin surface. The polygonal design of the light-transmitting element 200 increases the light-emitting area, providing a wider coverage area for light energy, thereby enhancing the cosmetic effect.

[0052] Furthermore, the polygonal light-emitting surface 200a of the light-transmitting element 200 offers significant advantages over circular or curved designs when treating uneven areas such as the nose and the corners of the eyes. A circular light-emitting surface 200a often fails to reach deep into the skin in these areas, while a polygonal design, with its multiple corners, allows for more precise treatment. Therefore, the polygonal light-transmitting element 200 offers greater flexibility and improved results when treating detailed areas.

[0053] Furthermore, if the light-emitting end surface 200a of the light-transmitting member is circular or arc-shaped, and the electrodes 400 are arranged around the light-transmitting member, the shapes of the multiple electrodes 400 may also be circular or arc-shaped (if they are not arranged in an arc-shaped or circular shape, there will be more blank areas between the electrodes 400 and the light-emitting end surface 200a). This layout may reduce the conduction efficiency of the electrodes 400 and make the current path unstable, which is not conducive to the conduction and operation of the electrodes.

[0054] For example, if two opposing electrodes 400 are curved along the edge of the light-emitting end surface 200a, the curvature of the current path between the two curved electrodes will be disrupted. Specifically, current tends to travel along the shortest straight path, but the curvature of the curved electrodes 400a may cause the current path to become longer or more inconsistent, thereby increasing resistance and reducing current conduction efficiency. This obstruction can affect the overall performance of the electrodes, leading to uneven current distribution and, consequently, the effectiveness of cosmetic treatments.

[0055] In this embodiment, the edges of the light-emitting end face 200a of the light-transmitting element are polygonal. Therefore, the electrodes 400 can be positioned on relatively straight edges of the polygonal light-transmitting element 200, thereby making the current transmission path more direct and efficient. Compared to electrodes 400 with curved or circular edges, electrodes 400 with straight edges can form a straight, shortest path. This linear current path reduces resistance during current conduction, allowing current to be transmitted quickly with minimal loss.

[0056] In this embodiment, the light-transmitting element 200 can be made of sapphire. Sapphire is widely used in high-end optical devices due to its high light transmittance, high-temperature resistance, and wear resistance. It effectively conducts light and maintains excellent stability during extended use, preventing deformation or damage due to heat accumulation. Furthermore, sapphire's high hardness makes it highly resistant to external physical damage, extending the life of the device.

[0057] The light emitting device 300 is disposed within the housing 100 and radiates light toward the light-transmitting member 200, thereby providing skin care through the light-transmitting member 200. The light emitting device 300 can utilize various light sources, such as an LED lamp, a halogen lamp 500, or a xenon lamp. These light sources can achieve different cosmetic effects depending on their wavelength and intensity.

[0058] Specifically, LED lights have the advantages of long life and low energy consumption, and are often used for general beauty treatments such as whitening, freckle removal, and wrinkle reduction. Different wavelengths of LED light can target different skin concerns. For example, blue light can be used to kill bacteria and reduce inflammation, while red light can help promote collagen production.

[0059] The halogen lamp 500 has a high luminous intensity and is suitable for deep skin care, such as wrinkle removal and skin tightening. The broad spectrum of light it emits can effectively penetrate the surface of the skin and stimulate deep tissues.

[0060] Xenon lamps, with their high brightness and strong penetrating power, are commonly used in beauty treatments such as photorejuvenation. They produce intense pulsed light, which has a significant effect on skin problems such as pigmentation and capillary dilation.

[0061] In addition, different wavelengths of light have different cosmetic effects. For example, blue light with a wavelength of 400-500nm is suitable for eliminating skin inflammation; red light with a wavelength of 600-700nm helps promote blood circulation and cell regeneration, enhancing skin elasticity; and near-infrared light (800-1000nm) can penetrate deep into the subcutaneous tissue, helping to reduce inflammation and accelerate skin repair.

[0062] The electrodes are primarily used to deliver microcurrent and / or radiofrequency current to the skin, further enhancing the cosmetic effect. The electrodes' position and shape are designed to conform to the polygonal edges of the light-transmitting element 200, ensuring even distribution of electrical energy. The electrodes can be made of highly conductive and skin-safe materials, such as stainless steel, silver, or gold-plated copper. These materials not only effectively conduct current but also exhibit excellent corrosion resistance, ensuring the device's long-term stability.

[0063] In this embodiment, the example of pairing opposite electrodes into electrode pairs is used to realize interleaving current. Of course, in some embodiments, adjacent electrodes can be paired into electrode pairs. For example, when a rotating current path is required, adjacent electrodes can be alternately paired into electrode pairs to realize interleaving current. The following is an example of interleaving current:

[0064] During use, the light emitted by the light-emitting device 300 is guided by the light-transmitting member 200 and evenly illuminates the skin surface. If the edge of the light-emitting end face 200a of the light-transmitting member is polygonal, the electrode 400 can be set on the relatively straight edge of the polygonal light-transmitting member 200, and the current transmission path will become more direct and efficient. Compared with the layout of the electrodes 400 with arc or circular edges, a straight shortest path can be formed between the electrodes 400 with opposite straight edges. This linear current path reduces the resistance of the current during conduction, allowing the current to be transmitted quickly with less loss. At the same time, the electrodes are arranged at intervals on the periphery of the light-transmitting member 200 to ensure that the microcurrent and / or radiofrequency current is evenly transmitted to the area where the light energy acts on the skin, and acts together with the light energy in the same skin area.

[0065] Since the number of sides of the light-emitting end face 200a is greater than four, electrodes can be installed on more sides. As the number of sides increases, the number of electrodes also increases accordingly. For example, in a hexagonal, octagonal or decagonal light-transmitting element 200 design, an electrode can be installed on each side, so that the device can accommodate more electrodes. As the number of electrodes increases, the current output between the electrodes on the opposite sides forms a more dense interwoven current field. Each pair of opposing or adjacent electrodes forms a current pair, and these current pairs are interwoven to form a dense current network. This densely interwoven current can more evenly cover the skin surface of the light-emitting area of ​​the light-transmitting element 200, ensuring that each part is uniformly electrically stimulated.

[0066] Due to the polygonal structure of the light-emitting end surface 200a of the light-transmitting element 200, light energy passes through the light-transmitting element 200 and is evenly irradiated onto the skin surface. Simultaneously, the finely interwoven currents output by multiple electrodes on opposite sides also act on the same area. This synergistic effect enables light energy and current to act simultaneously on the skin's surface and deeper tissues. Light energy activates skin cells through a photothermal effect, while the finely interwoven currents further stimulate cell activity, enhancing the light energy's therapeutic effects.

[0067] In other words, by increasing the number of sides of the light-emitting end surface 200a of the light-transmitting element 200, more electrodes can be installed, thereby increasing the total effective working area of ​​the device. More electrodes mean a wider current coverage area. The synergistic effect of the finely interwoven current and light energy can more comprehensively cover the skin surface and deeper tissues, thus expanding the coverage area of ​​the treatment and increasing the total effective area of ​​the device as a whole.

[0068] In the technical solution of the present invention, a light-emitting device 300 is disposed within the housing 100 and directed toward the light-transmitting member 200 to provide skin care through the light-transmitting member 200. Simultaneously, multiple electrodes 400 are distributed around the periphery of the light-transmitting member 200 to output microcurrent and / or radiofrequency current to the skin, enabling the skin care device 10 to possess both light-treatment and current-stimulation treatment functions. By designing the light-emitting end face 200a of the light-transmitting member 200 as a polygon with more than four sides, more electrodes can be installed. Increasing the number of electrodes means a greater current coverage area. The densely interwoven current and light energy more comprehensively cover the same skin area, effectively increasing the device's total effective working area and maximizing the surface area of ​​the working head 102.

[0069] Continue reading Figure 1 In this embodiment, the number of electrodes is equal to the number of sides of the light emitting end surface 200 a , and each electrode is correspondingly arranged at intervals on the periphery of one side of the light emitting end surface 200 a .

[0070] In this embodiment, the number of electrodes is equal to the number of edges of the light-emitting end surface 200a of the light-transmitting element 200. In other words, each electrode is spaced apart and positioned around the periphery of one edge of the light-emitting end surface 200a. This design ensures that the electrodes precisely match the edges of the light-transmitting element 200, allowing each electrode to be evenly distributed around the light energy output area when the device is operating. This not only increases the effective contact area between the electrodes and the skin, but also ensures that the electrical energy and light energy are evenly distributed across the skin, avoiding overstimulation or uneven skin care effects caused by energy concentration in a single area.

[0071] In the design where the number of electrodes is consistent with the number of sides of the light-emitting end face 200a, the uniform distribution of current and the uniform output of light energy complement each other, forming a good synergistic effect. Since the electrodes are evenly distributed in the surrounding area of ​​the light energy output, light energy and electrical energy can act simultaneously on the surface of the skin, producing a more significant cosmetic effect. Light energy can stimulate the activity of cells on the surface of the skin, while electric current can penetrate into the skin tissue, promoting the production of collagen and blood circulation. The combination of the two effectively improves the overall health of the skin and improves skin quality and elasticity. At the same time, the uniform distribution of current and light energy also reduces skin discomfort and improves the user experience and safety. Therefore, this embodiment achieves a more efficient electro-optical synergistic care effect through the design of matching the number of sides of the electrodes with the light-emitting end face 200a.

[0072] Further, see Figure 1 and Figure 2 , the light-emitting end face 200a is a regular polygon.

[0073] In this embodiment, the light-emitting end face 200 a is a regular polygon. This geometric shape has the characteristics that all sides of the polygon are equal in length and angle, making the distribution of the electrodes more regular and uniform.

[0074] Specifically, since the sides of a regular polygon are of equal length, the electrodes can be evenly spaced around the periphery of each side. This ensures that the current is evenly distributed throughout the device working head 102, without causing current concentration or dispersion due to a side being too long or too short.

[0075] Furthermore, because the sides of a regular polygon are of equal length, the electrodes can be evenly spaced around each side. This regular polygon design makes more efficient use of the device head's surface area. This maximizes the position of each electrode, reducing unused area on the device head and increasing the overall effective working area, thereby enhancing the device's coverage.

[0076] Therefore, the use of a regular polygonal light-emitting end face 200a in this embodiment not only optimizes the distribution of electrodes, making current conduction more uniform and effective, but also improves the overall care effect and usage efficiency of the device.

[0077] See Figures 4 to 6 , Figure 4 for Figure 3 Schematic diagram of the local structure at B in the middle. Figure 5 This is a schematic diagram of the exploded structure of a skin care device in one embodiment of the present invention. Figure 6 Schematic diagram of the exploded structure of the working head 102 in one embodiment of the present invention.

[0078] In this embodiment, the number of sides of the light-emitting end face 200a is six;

[0079] Alternatively, the number of sides of the light-emitting end face 200a is eight;

[0080] Alternatively, the number of sides of the light emitting end face 200a is ten.

[0081] In this embodiment, the light-emitting end surface 200 a of the light-transmitting element 200 is designed as a polygon with an even number of sides. Specifically, the number of sides of the light-emitting end surface 200 a may be six, eight, or ten.

[0082] The even number of sides on the light-emitting end face 200a ensures symmetry and balanced electrode distribution. Each electrode can be installed in a symmetrical geometric position, creating a uniform current conduction path. This balanced design ensures even current distribution across the device head, eliminating current imbalance or localized overconcentration caused by an asymmetric number of sides, ensuring consistent and safe skin care results.

[0083] The even-numbered design optimizes the synergistic effect of light and electrical energy. Light energy is uniformly distributed through the polygonal light-transmitting element 200, where it interacts with the current generated by the equally spaced electrodes on the skin surface. Each electrode is evenly distributed around the periphery of the light-transmitting element 200, synchronizing with the light energy to effectively cover the skin care area and enhance the overall cosmetic effect.

[0084] Specifically, the light emitting end surface 200 a is octagonal, and the corresponding opening of the working head 102 is also designed to be octagonal, so as to facilitate the installation of the light-transmitting element 200 on the housing 100 .

[0085] Compared to the circular light-transmitting member 200 in the related art, the light-transmitting member 200 provided in the embodiment of the present application has an octagonal light-emitting end surface 200a, which can provide care for relatively narrow areas of the human body, such as the nose, and compared to quadrilateral or triangular shapes, the octagonal light-emitting end surface 200a in the present application has a better fit for smoother areas of the skin. Therefore, the octagonal design of the light-emitting end surface 200a can not only provide care for narrow areas of human skin, but also maximize the area of ​​fit for the skin, thereby achieving a better care effect of the skin care device 10 provided in the embodiment of the present application.

[0086] In summary, by refining the design of the number of sides of the light-emitting end face 200 a and adopting a polygon with an even number of sides, this embodiment improves the balanced distribution of current and the photoelectric synergy effect.

[0087] See Figure 7 , Figure 7 FIG. 1 is a structural diagram of a skin care device 10 in another embodiment of the present invention.

[0088] In this embodiment, the number of sides of the light emitting end surface 200a is an even number, and the ratio of the number of electrodes to the number of sides of the light emitting end surface 200a is 1:2, wherein each electrode is correspondingly arranged at intervals on the periphery of at least two sides of the light emitting end surface 200a.

[0089] In this embodiment, the light-emitting end face 200a of the light-transmitting element 200 is designed to have an even number of sides, and the ratio of the number of electrodes to the number of sides of the light-emitting end face 200a is 1:2. This means that one electrode can be correspondingly arranged on the periphery of at least two sides of the light-emitting end face 200a. In other words, each electrode can be arranged across the edges of two light-emitting end faces 200a. In this way, when one electrode covers two sides of the light-emitting end face 200a, the coverage of the electrode can be increased (see Figure 6 As can be seen, the edge of the electrode near the light-emitting end face remains straight, with the ends extending to curve along the edge corners. This design allows the current to more broadly cover the area surrounding the light-transmitting element 200, thereby ensuring electrical stimulation over a larger area of ​​the skin surface. This increased current coverage increases the breadth of the treatment area, helping to achieve a more uniform and comprehensive cosmetic effect.

[0090] Continue reading Figure 1 and Figure 2 、 Figure 7 and Figure 8 In this embodiment, the electrodes are arranged around the edge of the light-emitting end face, and the distance between each electrode and the edge of the corresponding light-emitting end face 200a is equal;

[0091] And / or, the distances between adjacent electrodes are the same;

[0092] And / or, the electrode is parallel to the edge of the corresponding light-emitting end face.

[0093] In this embodiment, the distance between each electrode and the edge of the corresponding light-emitting end face 200a is equal, which can make the distribution of current on the working head 102 of the device more uniform. This uniform distribution avoids the phenomenon of excessive concentration or sparseness of current on the skin surface, and reduces the problem of local overheating or poor effect caused by uneven current. Uniform current distribution helps to improve the overall care effect, so that every part of the skin can obtain the same electrical stimulation. Moreover, when the distance between each electrode and the edge of the light-emitting end face 200a is equal, the range of action of the electrode and the light energy highly overlap. This ensures that the current and light energy act synchronously on the skin surface, producing a more stable synergistic effect. It avoids the problem of misalignment of the range of action of current and light energy, ensuring that each part of the skin can receive corresponding electrical stimulation while receiving light energy irradiation, thereby improving the overall effect of care.

[0094] The equal distance design reduces current attenuation during conduction, ensuring that each electrode outputs the same current intensity in the same mode. Because the electrodes are at the same distance from the edge of the light-emitting surface 200a, the current is more evenly distributed between each electrode, improving the effectiveness and consistency of the current during skin care.

[0095] Furthermore, the spacing between adjacent electrodes 400 is designed to be the same. Specifically, taking the light-emitting end face of the light-transmitting element 200 as an octagon, eight electrodes 400 are respectively installed on eight edges. The distance between the end edges of every two adjacent electrodes 400 remains equal.

[0096] When adjacent electrodes 400 are spaced the same distance apart, current is more evenly distributed across the entire head of the device. This even spacing between electrodes 400 prevents excessive current from being generated in certain areas due to excessive concentration of electrodes, while also preventing uneven current distribution caused by excessive spacing between electrodes 400. This uniform current distribution ensures consistent current stimulation throughout the treatment process, thereby improving overall effectiveness.

[0097] Furthermore, when the electrodes 400 are evenly spaced, the current coverage on the skin surface more closely matches the light energy area projected by the light-transmitting element. The uniform current distribution and the uniform light energy area work together to achieve more effective synergistic care. This synergistic effect not only enhances the cosmetic effect but also provides more comprehensive skin care during the treatment process.

[0098] Furthermore, the electrodes are parallel to the edges of the corresponding light-emitting end faces 200a, meaning that the electrodes 400 have a certain length. The edges of individual electrodes 400 are parallel to the edges of the corresponding light-emitting end faces 200a, allowing the electrodes 400 to conform to the shape of the light-emitting end faces 200a. This not only helps reduce space usage but also ensures that the current coverage on the skin surface is more closely aligned with the light energy area projected by the light-transmitting element 200. The combined effect of uniform current distribution and uniform light energy area enables more effective synergistic care.

[0099] Continue reading Figure 7 In this embodiment, the edges of the light emitting end surface 200a are opposite to each other in pairs, and the electrodes 400 arranged on the opposite edges of the light emitting end surface 200a are symmetrically arranged with respect to at least one axis F of the light emitting end surface 200a.

[0100] In this embodiment, the light-emitting end face 200a of the light-transmitting element is designed as an octagon, and the edges of the light-emitting end face 200a are opposite to each other. An electrode 400 is provided on each opposite edge, and these electrodes 400 are symmetrically arranged with respect to the axis F of the light-emitting end face 200a.

[0101] When the electrodes 400 are symmetrically distributed on the edge of the light-emitting end surface 200a, the path of current conducted from one electrode 400 to the other symmetrical electrode 400 is symmetrical and equal. This symmetry ensures that the current is evenly distributed on the skin surface.

[0102] At the same time, the symmetrical arrangement of electrodes 400 can effectively reduce interference between current fields. The current path of each electrode 400 forms an independent and balanced current field with the electrode 400 opposite to it, avoiding cross interference between current paths.

[0103] Furthermore, the symmetrical arrangement of electrodes 400 ensures a better match between the current field and the area of ​​light energy applied. Light energy is evenly distributed across the skin surface along axis F of the light-transmitting element 200, while the symmetrical arrangement of electrodes 400 creates a symmetrical current field within the same area. This symmetrical combination of light energy and current ensures that every part of the skin receives uniform, dual stimulation from light and electricity, enhancing the skin's care effectiveness.

[0104] In addition, in the embodiment where each electrode 400 is disposed at intervals on the periphery of at least two edges of the light emitting end surface 200a, the electrodes 400 disposed on the opposite edges of the light emitting end surface 200a are also symmetrically disposed about at least one axis F of the light emitting end surface 200a. Figure 8 . In this embodiment, by covering the edges of the two light-emitting end surfaces 200a with one electrode 400, this embodiment effectively increases the coverage area of ​​the electrode 400, which makes the contact area between the electrode 400 and the skin larger, helping to reduce contact resistance and improve current conduction efficiency. At the same time, the symmetrical arrangement of the electrodes 400 ensures the uniformity and minimization of the current path, further reducing resistance. The symmetrical layout balances the current distribution and avoids the increase in local resistance caused by current concentration under the asymmetric layout, thereby optimizing the overall current conduction performance and enhancing the care effect and stability of the device.

[0105] See Figure 5 and Figure 6 In this embodiment, the light-transmitting member 200 includes a light-transmitting member body 201 and an annular flange 202. One end of the light-transmitting member body 201 is embedded in the opening, and the annular flange 202 is protruded from the outer periphery of the other end of the light-transmitting member body 201 and abuts against the outer periphery of the opening; and / or, the light-transmitting member 200 is sapphire.

[0106] In this embodiment, the light-transmitting member 200 comprises a light-transmitting member body 201 and an annular flange 202. One end of the light-transmitting member body 201 is embedded within the opening of the device, while the annular flange 202 protrudes from the outer periphery of the other end of the light-transmitting member body 201 and abuts the outer periphery of the opening. To ensure structural stability and precision, the light-transmitting member body 201 and the annular flange 202 in this embodiment can be designed as an integral unit. This integral unit can be achieved through precision machining processes such as CNC machining or laser cutting. These machining methods can ensure high precision and high quality, particularly when the light-transmitting member 200 is made of sapphire.

[0107] The integrated molding ensures the overall strength and stability of the light-transmitting element 200, preventing loosening or displacement that could occur due to separate components. Furthermore, the annular flange 202 increases the contact area between the light-transmitting element 200 and the device opening, thereby enhancing the secure and airtight installation. This design not only improves the durability of the device but also reduces the impact of external environmental factors on the light-transmitting element 200, such as the intrusion of dust or liquids, thereby extending the device's service life.

[0108] In addition, the design of the light-transmitting element 200 using sapphire material further enhances the performance of the device. Sapphire has the characteristics of high light transmittance, high temperature resistance, and wear resistance, making it excellent in conducting light energy and protecting the internal components of the device. The light-transmitting element 200 with an annular flange 202 design not only ensures the effective transmission of light energy, but also ensures that the light transmission process is not interfered with by external factors through its secure installation. Overall, the design of this light-transmitting element 200 not only improves the operating efficiency and stability of the device, but also enhances the user experience and safety of the device, ensuring that excellent performance can be maintained during long-term use.

[0109] Continue reading Figure 5 and Figure 6 In this embodiment, the housing 100 also includes a first side shell 105 and a second side shell 106. The first side shell 105 and the second side shell 106 are connected to each other, and the end shell 104 is connected to one end of the first side shell 105 and the second side shell 106. The end shell 104 forms a working head 102, and the end shell 104 is a polygonal cone.

[0110] In this embodiment, the housing 100 is composed of an end housing 104, a first side housing 105, and a second side housing 106. Specifically, the interconnected first and second side housings 105, 106 form the device's main structural framework, while the end housing 104 is connected to the other ends of the first and second side housings 105, 106, forming the device's working head 102. The end housing 104 is designed as a polygonal cone, which not only enhances the device's aesthetics but also provides several functional advantages.

[0111] The polygonal tapered end housing 104 plays a key role in the overall structure and performance of the device. First, this shape provides excellent space utilization, allowing for a more compact arrangement of internal components and reducing the device's size. Furthermore, the polygonal tapered design helps guide the focus of light or other energy forms (such as electric current or radio frequency), thereby improving the device's efficiency and effectiveness. For the skin care device 10, the polygonal tapered working head 102 enables more precise contact with the skin surface, achieving more uniform energy output.

[0112] The design of the housing 100 in this embodiment, particularly the interconnection between the first side housing 105 and the second side housing 106, provides extremely high structural stability. The tight connection between the two housings not only ensures the robustness of the device during use but also enhances its durability. In some embodiments, the first side housing 105, the second side housing 106, and the end housing 104 can be formed in one piece, using a specific process such as injection molding.

[0113] Continue reading Figure 5 and Figure 6 In this embodiment, the housing 100 includes an end shell 104 , and the electrode 400 includes an electrode sheet 402 and an electrode column 403 . The electrode sheet 402 is located at the outer edge of the end shell 104 , and the electrode column 403 extends from the electrode sheet 402 and penetrates the end shell 104 .

[0114] In this embodiment, each electrode 400 is designed to consist of two parts: an electrode sheet 402 and an electrode column 403. The electrode sheet 402 is located on the outer edge of the device's end housing 104, providing direct contact with the skin and conducting current. The electrode column 403 extends from the electrode sheet 402 and passes through the interior of the end housing 104, conducting current to the electrode sheet 402. This design ensures efficient current transmission while also improving the overall structural stability of the electrode.

[0115] The electrode sheet 402 is designed to be located at the outer edge of the end housing 104 and is mainly used for direct contact with the skin. The electrode sheet 402 can be made of a flexible conductive material to enhance the fit with the skin while ensuring good electrical conductivity.

[0116] In addition, the design of the electrode sheet 402 is not limited to a flat shape, but can also be designed as an arc structure. For specific structures, please refer to Figure 4 One side of the arc-shaped electrode sheet 402 extends to the outer edge of the end shell 104, forming a natural transition with the shell. This arc-shaped design has significant advantages when caring for irregular skin areas (such as the eye sockets, mouth and nose areas).

[0117] The arc-shaped electrode piece 402 is combined with the end shell 104 in a polygonal cone shape, which can further improve the fit with the natural curve of the skin. Especially when caring for irregular skin areas, such as the eye sockets, around the mouth and nose, the electrode piece 402 can fit closely to the skin of these complex areas, reducing poor contact or excessive local pressure, thereby improving the efficiency and uniformity of current conduction. At the same time, this fit improves the user's comfort.

[0118] Furthermore, the natural transition between the curved electrode pads 402 and the housing not only enhances the aesthetics of the device but also strengthens the overall structural strength of the housing. The curved design avoids sharp transitions or protrusions between the electrode pads 402 and the housing, reducing wear and tear during use and providing a gentler and more precise operating experience when treating irregular skin areas.

[0119] By designing the electrode sheet 402 to be arc-shaped and extending it to part of the outer edge of the shell, the fit and comfort of the electrode to the skin are improved when treating irregular skin areas (such as the eye sockets, mouth and nose areas). At the same time, the effective coverage range of the current is expanded, and the appearance and structural strength of the device are optimized, thereby providing users with a more efficient and comfortable care experience.

This light has a broad spectrum, covering multiple wavelengths from visible light to near-infrared light, thereby achieving a variety of skin care functions. For example, in a beauty device, the red light emitted by the halogen lamp 500 helps improve skin elasticity and reduce wrinkles, while the near-infrared light promotes blood circulation and accelerates skin repair. In a hair removal device, the high-energy light from the halogen lamp 500 can effectively destroy hair follicles, achieving long-lasting hair removal.

[0124] The skin care device 10 in this embodiment can be designed as a beauty device or a hair removal device, depending on the device's application scenario and user needs.

Whether used as a beauty device or a hair removal device, the use of a halogen lamp 500 effectively enhances the device's functionality.

[0125] In beauty device applications, the multi-band light emitted by the halogen lamp 500 can provide customized treatments for various skin concerns, such as skin rejuvenation, wrinkle reduction, and freckle removal. By adjusting the spectrum and intensity of the halogen lamp 500, the device can achieve a variety of beauty effects to meet the needs of different users. In hair removal applications, the high-intensity light beam of the halogen lamp 500 can precisely target hair follicles, inhibiting hair regrowth and providing long-lasting hair removal results.

The halogen lamp 500's efficient light output, stability, and multi-band coverage make the device a powerful advantage in various skin care applications, ensuring that users receive the desired results and experience during different treatment processes.

[0127] It should be noted that the multiple electrodes 400 are at least partially exposed from the shell 100, which may include a situation where the electrode 400 is protruding from the shell 100, or a situation where the electrode 400 is flush with the surface of the shell 100, or a situation where the electrode 400 is recessed at a certain distance from the surface of the shell 100. The purpose is to enable the electrode 400 to output microcurrent and / or radiofrequency current to the skin during the contact between the electrode 400 and the skin.

[0128] In addition, since the electrode has a width, the distance from the electrode 400 to the corresponding light-emitting edge refers to the distance between the side of the electrode 400 close to the light-emitting edge and the light-emitting edge, and the distance between adjacent electrodes 400 refers to the distance between the sides of the adjacent electrodes 400 close to each other.
