[0036] The embodiments of this utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figures 1-6 The description of the housing 10 for a nursing head 100 according to an embodiment of the present utility model includes: housing 10.

[0037] Specifically, such as Figures 1-6As shown, the housing 10 includes a first housing portion 11 and a second housing portion 12. The second housing portion 12 is disposed on the outer peripheral side of the first housing portion 11. The first housing portion 11 and the second housing portion 12 are connected. The first housing portion 11 forms a first nursing surface 13, and the second housing portion 12 forms a second nursing surface 14. The first nursing surface 13 and the second nursing surface 14 are connected. The first nursing surface 13 and the second nursing surface 14 are curved surfaces. The first nursing surface 13 is recessed towards the central region of the housing 10 along a first direction A.

[0038] Combination Figures 1-3 The second housing portion 12 is disposed around the outer periphery of the first housing portion 11. The first housing portion 11 and the second housing portion 12 are connected to form a whole and together form a continuous curved surface. This curved surface is composed of a first care surface 13 and a second care surface 14. The first care surface 13 is designed to be recessed towards the central region of the housing 10, that is, the first care surface 13 is a concave curved surface with a certain curvature. The second care surface 14 is connected to the first care surface 13 by a circular arc transition to form a continuous arc-shaped curved surface. The edge of the second care surface 14 away from the first care surface 13 is recessed towards the central region of the housing 10 along the second direction B. The first direction A and the second direction B are perpendicular. The first direction A is the length direction of the housing 10, and the second direction B is the width direction of the housing 10.

[0039] According to an embodiment of the present invention, the curved design of the housing 10 for the care head 100, specifically the first care surface 13 and the second care surface 14, allows the housing 10 to better conform to the user's facial contours, resulting in a good lifting effect. The concave design of the first care surface 13 increases the contact area between the housing 10 and the face, facilitating energy focusing and increasing the power of the first care surface 13. Furthermore, the design of the second care surface 14 makes the care head 100 more stable and easier to slide along the face during use, better conforming to the user's nasolabial fold contours and facilitating smooth sliding. The design of the housing 10 improves the user experience of the care head 100, providing better comfort and care effects during facial care, thus enhancing the user experience.

[0040] According to some embodiments of this utility model, such as Figures 1-5As shown, the housing 10 has a first direction A and a second direction B. 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. The radius of curvature of the profile of the first nursing surface 13 along the first direction A is R1, and the radius of curvature of the profile of the second nursing surface 14 along the second direction B is R2. R1 and R2 satisfy: R2 < R1. Specifically, the radius of curvature R1 of the first nursing surface 13 in the first direction A satisfies: 130mm ≤ R1 ≤ 180mm; and / or, the radius of curvature R2 of the second nursing surface 14 in the second direction B satisfies: 10mm ≤ R2 ≤ 15mm. And / or, the radius of curvature R1 of the first nursing surface 13 in the first direction A and the radius of curvature R2 of the second nursing surface 14 in the second direction B. The profile of the first nursing surface 13 along the first direction A is the first profile line 17, and the profile of the second nursing surface 14 along the second direction B is the second profile line 18.

[0041] The first care surface 13 and the second care surface 14 have different radii of curvature in the first direction A and the second direction B, respectively, with R2 < R1. This means the second care surface 14 has a greater curvature in the second direction B, making it more curved. This allows the shell 10 to better adapt to different parts of the face, such as the forehead, cheekbones, and jawline, thereby improving fit. By limiting the range of curvature radii, the shell 10 is neither too flat nor too curved, ensuring sufficient fit without causing pressure on the user, thus improving comfort and stability.

[0042] Therefore, 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. This allows the housing 10 to better adapt to the main contour features of the face, enabling the care head 100 to better cover the target area during use and improve the care effect. Limiting the range of the curvature radius of the first care surface 13 in the first direction A and the second care surface 14 in the second direction B allows the surface of the housing 10 to be suitable for most facial contours, improving the versatility, fit, and comfort of the care head 100, and further enhancing the user experience.

[0043] According to some embodiments of this utility model, such as Figures 1-3 As shown, the length of the first nursing surface 13 along the first direction A is L1, where L1 satisfies: 70mm ≤ L1 ≤ 100mm; the length of the first nursing surface 13 along the second direction B is L2, where L2 satisfies: 35mm ≤ L2 ≤ 50mm; and / or, L1 / L2 satisfies: 0.8 ≤ L1 / L2 ≤ 2; and / or, the area of ​​the first nursing surface 13 is S1, where S1 satisfies: 1300mm². 2 ≤S1≤2800mm 2 The area of ​​the second nursing surface 14 is S2, and S2 satisfies: 1300mm² 2 ≤S1≤2800mm2 .

[0044] By limiting the length range of the first care surface 13 in the first direction A and the second direction B, and the area range of the first care surface 13 and the second care surface 14, it can be ensured that the shell 10 is neither too large nor too small, fully covering the facial area without being too bulky or inconvenient to carry. By limiting the length ratio in the first direction A and the second direction B, it can be ensured that the shell 10 can fit closely to different parts of the face during use, improving the care effect.

[0045] Therefore, a reasonable size and area design can improve user comfort and avoid discomfort caused by improper size, so that the care head 100 can provide a more comfortable and efficient care experience.

[0046] According to some embodiments of this utility model, such as Figures 1-3 As shown, the second nursing surface 14 smoothly transitions to the first nursing surface 13. The side of the second nursing surface 14 away from the first nursing surface 13 protrudes along the third direction C toward the direction away from the center region of the housing 10 and then is recessed toward the center region of the housing 10. The third direction C, the first direction A, and the second direction B are orthogonal to each other.

[0047] The second nursing surface 14 protrudes outward along the third direction C on the side away from the first nursing surface 13, and then indents inward, forming a smooth curved surface structure on the outer periphery of the housing 10.

[0048] Therefore, the smooth transition between the second treatment surface 14 and the first treatment surface 13 ensures that there are no obvious sharp edges or protrusions at the connection between the two treatment surfaces, preventing discomfort to the user during use. The smooth transition design also helps to improve the product's aesthetics. The structure of the first treatment surface 13 and the second treatment surface 14 ensures that the shell 10 can fit snugly against the user's face in multiple dimensions and is suitable for different areas of the face, improving the uniformity and effectiveness of the treatment.

[0049] According to the second aspect embodiment of the present utility model, the nursing head 100, combined with Figures 1-4 The nursing head 100 includes: a housing 10, an electrode assembly 20, and a drive circuit board. The housing 10 is the housing 10 for the nursing head 100 according to the first aspect embodiment of the present invention described above. The electrode assembly 20 is disposed on the nursing surface, and the electrode assembly 20 is at least partially exposed on the nursing surface. The drive circuit board is disposed inside the housing 10 and is electrically connected to the electrode assembly 20.

[0050] The electrode assembly 20 is at least partially exposed on the treatment surface, meaning that at least a portion of the electrode assembly 20 can directly contact the user's skin to transmit current or other forms of energy. A drive circuit board is disposed inside the housing 10 and electrically connected to the electrode assembly 20. The circuit board is responsible for controlling the operating state of the electrodes, such as current intensity and frequency. Through the control of the drive circuit board, the electrode assembly 20 can support multiple operating modes, such as microcurrent, radio frequency, and ultrasound, enabling the treatment head 100 to be suitable for different care needs.

[0051] According to the embodiment of this utility model, the nursing head 100, by applying the housing 10 of the above embodiment, with both the first nursing surface 13 and the second nursing surface 14 on the housing 10 being curved surfaces and having a smooth transition between them, allows the nursing head 100 to better conform to the user's facial contours. Direct contact between the electrode assembly 20 and the skin ensures effective energy transfer during the nursing process, thereby improving the nursing effect. The electrical connection design between the drive circuit board and the electrode assembly 20 ensures safe current transmission. Controlling the working state of the electrodes through the internal circuit board effectively avoids the risk of overstimulation or electric shock, ensuring product safety.

[0052] According to some embodiments of this utility model, such as Figures 1-3 As shown, the electrode assembly 20 includes a first electrode sheet 21, which is disposed on the first care surface 13 and extends circumferentially along the housing 10.

[0053] The first electrode 21 extends circumferentially along the first care surface 13, ensuring that the first electrode 21 can be evenly distributed on the care surface, thereby providing a more uniform energy distribution during use.

[0054] Thus, the first electrode 21 extends circumferentially along the housing 10. The structure of the first electrode 21 can ensure that the current or energy is evenly distributed on the nursing surface, avoiding local over- or under-strength phenomena, thereby improving the nursing effect.

[0055] According to some embodiments of this utility model, such as Figures 1-3 As shown, the electrode assembly 20 further includes: a second electrode sheet 22, which is disposed on the outer periphery of the first electrode sheet 21 along the second direction B and extends along the first direction A. At least a portion of the second electrode sheet 22 is disposed within the first nursing surface 13 and at least a portion of the second electrode sheet 22 is disposed within the second nursing surface 14. The second electrode sheet 22 extends from the first nursing surface 13 to the second nursing surface 14.

[0056] There can be two second electrode pads 22, which are respectively disposed on both sides of the first electrode pad 21 along the second direction B, and the geothermal electrode pad extends along the first direction A. The second electrode pads 22 are present not only partially on the first care surface 13, but also partially on the second care surface 14. This design can ensure that the electrode pads cover a larger facial area and improve the comprehensiveness of the care.

[0057] Thus, the second electrode 22 extends from the first care surface 13 to the second care surface 14, which can better adapt to the complex contours of the face, especially in the transition area between different planes of the face. The second electrode 22 can ensure that the current or energy is more evenly distributed on the first care surface 13 and the second care surface 14 during the care process, achieving a wider care coverage and improving the care effect of the care head 100.

[0058] According to some embodiments of this utility model, such as Figures 1-3 As shown, the electrode assembly 20 further includes a third electrode sheet 23, which is disposed between the first electrode sheet 21 and the second electrode sheet 22. At least a portion of the third electrode sheet 23 is disposed within the first nursing surface 13, and at least a portion of the third electrode sheet 23 is disposed within the second nursing surface 14. The third electrode sheet 23 extends from the first nursing surface 13 to the second nursing surface 14.

[0059] The third electrode 23 is disposed along the outer periphery of the first electrode 21 along the first direction A, and the third electrode 23 is disposed between the two second battery plates along the second direction B. The third electrode 23 is disposed between the first electrode 21 and the second electrode 22, forming an additional electrode point. The third electrode 23 is disposed at one end of the housing 10 along the first direction A, and the third electrode 23 is suitable for caring for the periocular area.

[0060] Therefore, through the combined design of the first electrode plate 21, the second electrode plate 22 and the third electrode plate 23, the nursing head 100 can support multiple nursing modes and achieve more precise local nursing effects.

[0061] According to some embodiments of this utility model, such as Figures 1-3 As shown, the first electrode sheet 21 is formed as a ring electrode; or, the second electrode sheet 22 is formed as a strip electrode; or, the third electrode sheet 23 is formed as a point electrode. Alternatively, the second electrode sheet 22 may include both strip electrodes and point electrodes, and second electrode sheets 22 of different shapes are distributed simultaneously.

[0062] The first electrode pad 21 is formed into a closed ring structure on the first care surface 13. In some embodiments, the first electrode pad 21 includes a first sub-electrode pad 211 and a second sub-electrode pad 212, which can be a ring structure, with the first sub-electrode pad 211 surrounding the outer periphery of the second sub-electrode pad 212. The second electrode pad 22 is formed into a strip structure and extends along the first direction A. The third electrode pad 23 is formed into a dot structure and is disposed at the end of the housing 10 along the first direction A. The ring electrode can ensure that the current or energy is evenly distributed on the care surface, and the ring structure can better fit different parts of the face. Even if the head moves slightly during use, the electrode pad can still maintain good contact. The strip electrode can not only be arranged along the second direction B, but also extend along the first direction A, covering a larger facial area. The dot electrode can be precisely positioned to a specific area of ​​the face, and the dot electrode can concentrate the transmission of current or other forms of energy to a specific area, thereby enhancing the effect of local care.

[0063] Therefore, through the combination of ring electrodes, strip electrodes, and dot electrodes, the care head 100 can achieve multi-layered care effects, from full coverage to targeted intensive care. Ring electrodes provide basic, even care, strip electrodes expand the care area, and dot electrodes provide precise, localized care. The three different electrode shapes can adapt to different parts of the face, ensuring optimal care results in all directions.

[0064] According to some embodiments of this utility model, such as Figure 4 As shown, it also includes: a phototherapy component, which is disposed inside the housing 10 and electrically connected to the drive circuit board. The housing 10 has a light-transmitting part, and the phototherapy component is opposite to the light-transmitting part.

[0065] 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, located at positions on the first treatment surface 13 and the second treatment surface 14 where no electrode pads are present. The phototherapy component faces the light-transmitting portion, allowing the light emitted by the component to pass through and directly illuminate the user's skin. A light-shielding sleeve is used to block excess light, ensuring that the light is concentrated on the area requiring irradiation. A light guide block is used to further guide and diffuse the light, making its distribution more uniform. Alternatively, in this embodiment, both the first housing portion 11 and the second housing portion 12 are light-transmitting components.

[0066] 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.

[0067] The housing 10 also includes a third housing portion 15 and subsequently a fourth housing portion. One edge of the third housing portion 15 along the third direction C is adapted to connect with the outer periphery of the second housing portion 12. The outer periphery surface of the third housing portion 15 is an irregular annular curved surface. The fourth housing portion is opposite to the first housing portion 11 and the second housing portion 12 along the third direction C. The other edge of the third housing portion 15 along the third direction C is adapted to connect with the outer periphery of the fourth housing portion. The lamp plate and the adapter plate are respectively disposed on both sides of the third housing portion 15 along the third direction C. The lamp plate and the adapter plate are plugged into each other. The lamp plate is opposite to the light-transmitting portion, and the light emitted by the lamp plate can be irradiated through the light-transmitting portion.

[0068] Therefore, by integrating the electrode assembly 20 and the phototherapy assembly onto the same care head 100, a combination of electrotherapy and phototherapy can be achieved, providing a more comprehensive and diversified care effect. The phototherapy assembly can provide light of specific wavelengths, such as red light, blue light, or near-infrared light, which have different therapeutic effects, such as promoting cell regeneration, reducing inflammation and killing bacteria, and improving blood circulation. Combined with electrotherapy, the care effect can be further enhanced. By integrating multiple care functions into one device, users can more conveniently perform various care procedures without having to change different devices, improving ease of use and comfort, and enhancing the functional versatility of the care head 100.

[0069] According to some embodiments of the present invention, it further includes: a thermotherapy component, which is disposed inside the housing 10 and electrically connected to the drive circuit board. The thermotherapy component is disposed on the side of the electrode assembly 20 facing the center of the housing 10.

[0070] 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.

[0071] 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.

[0072] According to the third aspect of the present invention, the beauty care device, such as Figure 1 and Figure 6 As shown, it includes: a nursing head 100 and a handle 200. The nursing head 100 is the nursing head 100 according to the second aspect embodiment of the present invention described above. The nursing 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, the control circuit board and the nursing head 100 are electrically connected.

[0073] 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.

[0074] 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.

[0075] According to some embodiments of this utility model, such as Figure 1 and Figure 6 As shown, the nursing head 100 and the handle 200 can be detachably coupled, connected via a plug-in interface. Users can easily disassemble and install the nursing head 100, and can replace it with different nursing heads to suit different care needs. Alternatively, the nursing head 100 and the handle 200 can be a single, integrated unit, forming a complete device. This integrated design is generally more robust and durable, reducing problems caused by unstable connections.
