[0034] The embodiments of this utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figure 1-Figure 5 The nursing head 100 according to an embodiment of the present invention includes: a housing 10, an electrode assembly 20, and a phototherapy assembly.

[0035] Specifically, if Figure 1-Figure 5 As shown, the housing 10 has a care surface with at least one protrusion. The care surface includes a first care surface 11 and a second care surface 12, which smoothly transition. The protrusion protrudes towards a region away from the center of the housing 10, and the surface of the protrusion forms the second care surface 12. The protrusion is formed by at least a portion of the surface of the care surface protruding towards a region away from the center of the housing 10. The second care surface 12 is an outwardly convex curved surface with a certain curvature. The second care surface 12 and the first care surface 11 are connected by an arc transition, forming a continuous arc-shaped curved surface.

[0036] Combination Figure 1-Figure 5 The housing 10 has a first direction A and a second direction B, which are perpendicular to each other. An electrode assembly 20 is disposed within the housing 10, and includes a first electrode 21 and a second electrode 22. The second electrode 22 is disposed along the outer periphery of the first electrode 21 along either the first direction A or the second direction B. At least portions of the first electrode 21 and the second electrode 22 are disposed on the first care surface 11 and the second care surface 12. A phototherapy assembly is disposed within the housing 10, and at least a portion of the phototherapy assembly is opposite to the second care surface 12.

[0037] At least portions of the first electrode 21 and the second electrode 22 are disposed on the first care surface 11 and the second care surface 12, meaning that at least portions of the first electrode 21 and the second electrode 22 are exposed on the care surface. These portions can directly contact the user's skin to transmit current or other forms of energy. The placement of at least portions of the first electrode 21 and the second electrode 22 on the first care surface 11 and the second care surface 12 ensures a uniform distribution of the electrode assembly 20 on the care surface. The housing 10 has a light-transmitting portion, at least a portion of which is disposed on the second care surface 12. At least a portion of the phototherapy assembly is adapted to face the second care surface 12.

[0038] According to an embodiment of the present invention, the protrusions on the care surface of the nursing head 100 facilitate deep compression of adipose tissue by the user, thereby enhancing the care effect. The arrangement of the first electrode 21 and the second electrode 22 ensures uniform distribution of current or energy on the care surface, improving the comprehensiveness of the care. The phototherapy component can be used in conjunction with the electrode component 20 to further enhance the care effect of the nursing head 100 and increase its functional versatility.

[0039] According to some embodiments of this utility model, such as Figure 1-Figure 4As shown, the first nursing surface 11 is a convex surface, and the height of the protrusion of the first nursing surface 11 is less than the height of the protrusion of the second nursing surface 12.

[0040] The housing 10 has a third orientation, and the height of the first nursing surface 11 protruding in the third orientation of the housing 10 is less than the height of the second nursing surface 12 protruding in the third orientation of the housing 10.

[0041] As a result, the raised portion of the second care surface 12 is more prominent, which can provide a stronger squeezing and massage effect. By setting care surfaces of different heights, the care head 100 can adapt to the needs of different parts, making the care process more personalized and effective.

[0042] According to some embodiments of this utility model, such as Figure 4 As shown, the height difference between the first care surface 11 and the second care surface 12 is H, where H satisfies: 100mm ≤ H ≤ 180mm. The second care surface 12 is at least 100mm higher than the first care surface 11, and at most 180mm higher. This allows the second care surface 12 to protrude significantly from the first care surface 11, providing sufficient squeezing and massaging force. Therefore, by setting the first care surface 11 and the second care surface 12 at different heights, different care needs can be met by adjusting the different parts of the care head that contact the skin, increasing the flexibility of the care process.

[0043] According to some embodiments of this utility model, such as Figure 1-Figure 3 As shown, there are multiple protrusions, which are spaced apart on the nursing surface. The multiple protrusions include: a first protrusion 13, a second protrusion 14, a third protrusion 15, and a fourth protrusion. The first protrusion 13 and the second protrusion 14 are spaced apart at both ends of the nursing surface along a first direction A. The third protrusion 15 and the fourth protrusion are spaced apart at both ends of the nursing surface along a second direction B. The third protrusion 15 and the fourth protrusion are symmetrically distributed along the second direction B.

[0044] The first and second protrusions are spaced apart along the first direction A, which ensures that the pressure on the care surface of the care head 100 is relatively uniform during use, avoiding discomfort caused by excessive local compression. The symmetrical distribution of the third and fourth protrusions can improve the symmetry and balance of care, especially when caring for symmetrical areas, ensuring consistent care results on both sides.

[0045] Therefore, the design of multiple protrusions can adapt to the care needs of different areas. Whether it is horizontal or vertical massage, it can be achieved through these protrusions. When using the care head 100, users can use the multiple protrusions for targeted massage and compression. For areas that require deep compression, the angle of the care head 100 can be adjusted to bring a certain protrusion closer to the area that needs care, providing sufficient pressure and thus improving the care effect.

[0046] According to some embodiments of this utility model, such as Figure 3 As shown, the first electrode 21 has a frequency of f, where f satisfies: 0.5MHz≤f≤5MHz; and / or, the second electrode 22 is an EMS electrode.

[0047] The frequency range of the first electrode 21 is limited, allowing users to adjust the frequency of the first electrode 21 according to different care needs to achieve skin care effects. The second electrode 22 is an EMS (Electrical Muscle Stimulation) electrode. EMS electrodes are mainly used to stimulate muscle contraction by releasing current, thereby helping to strengthen muscle strength, improve blood circulation, and relieve symptoms such as pain.

[0048] Therefore, by limiting the frequency range of the first electrode 21 and using the second electrode 22 as an EMS electrode, the nursing effect of the nursing head 100 can be further improved, enhancing the overall nursing quality and user experience.

[0049] According to some embodiments of this utility model, such as Figure 1-Figure 4 As shown, the length of the housing 10 in the first direction A is greater than the length of the housing 10 in the second direction B; there are multiple first electrodes 21, which extend along the first direction A and are spaced apart along the second direction B.

[0050] A plurality of first electrodes 21 extend along a first direction A, at least a portion of the plurality of first electrodes 21 is located on a first care surface 11, and at least one end of a first electrode 21 along the first direction A is located on a second care surface 12.

[0051] Therefore, by having multiple first electrodes 21 extending along the first direction A and spaced apart in the second direction B, it is possible to ensure a more uniform distribution of current or energy across the entire treatment surface, thereby improving the treatment effect. The first electrodes 21 in the first direction A better adapt to the length of the user's face or other treatment areas, providing a wider coverage.

[0052] According to some embodiments of this utility model, such as Figure 3 As shown, there are multiple second electrodes 22, which are disposed on the outer periphery of the first electrode 21. The second electrodes 22 are spaced apart from the first electrode 21, and the multiple second electrodes 22 are symmetrically distributed along the second direction B.

[0053] There can be two second electrodes 22. The two second electrodes 22 are respectively disposed on both sides of the plurality of first electrodes 21 along the second direction B. The second electrodes 22 are disposed on the outer peripheral side of the first nursing surface 11 and extend along the circumferential direction of the first nursing surface 11.

[0054] Therefore, the placement of the second electrode 22 ensures a more uniform distribution of current or energy across the entire nursing surface, improving the nursing effect. The symmetrical distribution of the second electrode 22 along the second direction B ensures a more uniform pressure distribution on both sides of the second direction B during the nursing process, improving the consistency and symmetry of the nursing care. The placement of the second electrode 22 also increases the area of ​​the electrode assembly 20, ensuring that even the edge areas receive adequate care, achieving the best nursing effect.

[0055] According to some embodiments of this utility model, such as Figure 3 As shown, the distance between two adjacent first electrodes 21 is L, and L satisfies: 1mm≤L≤5mm.

[0056] Multiple first electrodes 21 are evenly spaced on the treatment surface, with a distance L between adjacent first electrodes 21. If the distance between two adjacent first electrodes 21 is less than 1 mm, the spacing is too small, and the current will concentrate in a small area, potentially leading to high local current density and excessive skin stimulation, causing discomfort. If the distance between two adjacent first electrodes 21 is greater than 5 mm, the spacing is too large, which may prevent the current from effectively covering the entire treatment area, resulting in insufficient electrical stimulation in some areas and weakening the treatment effect. For example, L = 3 mm.

[0057] Therefore, limiting the distance between two adjacent first electrodes 21 ensures a more uniform distribution of current or energy across the entire care surface. A reasonable electrode spacing reduces excessive localized irritation, ensuring safety and comfort during use. Furthermore, a well-designed spacing reduces manufacturing difficulty and cost, making the care head 100 more reliable and efficient in practical applications.

[0058] According to some embodiments of this utility model, such as Figure 3 As shown, the first electrode 21 is a strip electrode; or, the second electrode 22 is a strip electrode; or, the first electrode 21 is a strip electrode and the second electrode 22 is a strip electrode.

[0059] The strip electrode design ensures a more even distribution of current or energy across the entire treatment surface. Because the electrodes are strip-shaped, they better cover the treatment area, improving treatment effectiveness. Multiple strip electrodes can achieve multi-point stimulation, ensuring that the entire treatment area receives uniform electrical stimulation.

[0060] Therefore, with the first electrode 21 and / or the second electrode 22 designed as strip electrodes, the nursing head 100 can improve the comfort and effectiveness of use while ensuring uniform current distribution.

[0061] According to some embodiments of this utility model, such as Figure 3 As shown, along the first direction A, the width of the first electrode 21 is different, that is, the width of the first electrode 21 changes with the position; or, along the first direction A, the width of the second electrode 22 is different, that is, the width of the second electrode 22 changes with the position; or, along the first direction A, the width of the first electrode 21 is different and the width of the second electrode 22 is different.

[0062] Therefore, by changing the width of the electrodes, the nursing needs of different areas can be better adapted. For example, wider electrodes can be used for areas requiring intensive stimulation, while narrower electrodes can be used for areas requiring gentle care. Electrodes of different widths allow for targeted care of different areas, ensuring that each area receiving care receives appropriate stimulation. Adjusting the electrode width can reduce excessive local stimulation and improve user comfort.

[0063] According to some embodiments of the present invention, it further includes: a drive circuit board, which is disposed inside the housing 10, and the phototherapy component, the electrode component 20 and the drive circuit board are electrically connected respectively.

[0064] The drive circuit board is located inside the housing 10 and is electrically connected to the phototherapy component and the electrode component 20. The circuit board controls the operating state of the electrodes, such as current intensity and frequency. Through the control of the drive circuit board, the electrode component 20 can support multiple operating modes, allowing the care head 100 to be adapted to different care needs. The phototherapy component is connected to the drive circuit board via a circuit, enabling the circuit board to control the operation of the phototherapy component, including its operating state, such as current intensity, frequency, and other related parameters.

[0065] Therefore, the electrical connection design between the drive circuit board and the electrode assembly 20 and phototherapy assembly ensures safe current transmission. Controlling the electrode's operating state via the internal circuit board effectively avoids the risk of overstimulation or electric shock, ensuring product safety. Through unified control by the drive circuit board, the phototherapy assembly and electrode assembly 20 can work synergistically to achieve optimal treatment results.

[0066] According to some embodiments of this utility model, such as Figure 1 As shown, a light-transmitting portion is formed on the housing 10, and a phototherapy component is disposed inside the housing 10, with at least a portion of the phototherapy component facing the light-transmitting portion.

[0067] The phototherapy component is located inside the housing 10 and integrated with other components within the housing 10. The phototherapy component is connected to a drive circuit board via a circuit, allowing its operation to be controlled by the circuit board. A light-transmitting portion is formed on the housing 10 at locations where no electrode pads are provided on the first treatment surface 11 and the second treatment surface 12. The phototherapy component is positioned opposite the light-transmitting portion, allowing the light emitted by the component to pass through and directly illuminate the user's skin. Alternatively, in this embodiment, the housing 10 can be a light-transmitting element.

[0068] The phototherapy assembly includes a light panel, light guide columns, a light shield, a light film, a light guide block, and an adapter plate. The light panel is equipped with light-emitting elements that emit light of specific wavelengths. The light guide columns direct the light emitted from the light panel to the treatment surface. The light film diffuses the light, ensuring more even illumination on the skin. This multi-level light-guiding design of the light panel, light guide columns, light guide blocks, and light film ensures uniform light distribution on the treatment surface, preventing areas from being too bright or too dark, and improving the phototherapy effect.

[0069] Therefore, the phototherapy component can provide light of specific wavelengths, which have different therapeutic effects, further enhancing the care effect and increasing the functional versatility of the care head 100.

[0070] According to some embodiments of the present invention, it further includes: a thermotherapy component, which is disposed inside the housing 10 and on the side of the electrode component 20 facing the center of the housing 10.

[0071] The thermotherapy component is located inside the housing 10 and integrated with other components. It is connected to a drive circuit board via electrical circuitry, allowing its operation to be controlled by the circuit board. The thermotherapy component is positioned on the side of the electrode assembly 20 facing the center of the housing 10, i.e., on the back of the electrode assembly 20, rather than directly contacting the user's skin. The thermotherapy component can regulate the temperature of the motor assembly, helping to dilate blood vessels, promote blood circulation, and relieve muscle tension.

[0072] Therefore, by integrating the three care modes of electrotherapy, phototherapy, and thermotherapy, the Care Head 100 can provide more comprehensive and diversified care effects. Users can choose the appropriate care mode or combine multiple modes according to different needs.

[0073] According to the second aspect of the present invention, the beauty care device, such as Figure 1-Figure 5 As shown, the beauty care device includes: a care head 100 and a handle 200. The care head 100 is the care head 100 according to the first aspect embodiment of the present invention. The care head 100 is disposed on the handle 200, and the handle 200 is provided with a power supply and a control circuit board. The power supply and the control circuit board are electrically connected to the care head 100.

[0074] The treatment head 100 is mounted on the handle 200, making the entire device easy to hold and operate. The handle 200 contains a power source, which can be a rechargeable or disposable battery, to provide power to the treatment head 100. The handle 200 also contains a control circuit board for controlling various functions of the treatment head 100, including the operating status of the electrode assembly 20, phototherapy assembly, and thermotherapy assembly. The power source and control circuit board in the handle 200 are electrically connected to the treatment head 100 via wires, ensuring that all components can work together effectively.

[0075] According to an embodiment of the present invention, the beauty care device has an electrode assembly 20, a phototherapy assembly, and a thermotherapy assembly integrated into the care head 100, forming a multifunctional care system. By integrating the care head 100 with the handle 200, this beauty care device achieves a combination of portability and multifunctionality, ensuring both portability and ease of use.

[0076] According to some embodiments of this utility model, such as Figure 1 and Figure 5 As shown, the nursing head 100 and the handle 200 can be detachably coupled; or, the nursing head 100 and the handle 200 are an integral structural component.

[0077] According to some embodiments of this utility model, the nursing head 100 and the handle 200 can be detachably coupled, and are connected via a plug-in interface. Users can easily disassemble and install the nursing head 100, and can replace it with different nursing heads 100 as needed to adapt to different nursing requirements. Alternatively, the nursing head 100 and the handle 200 can be a single, integrated structure that cannot be disassembled, forming a complete device. This integrated design is generally more robust and durable, reducing problems caused by unstable connections. The integrated design also makes the device more compact and easier to operate with one hand.
