[0031] The embodiments of this utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figures 1-5 The nursing head 100 according to an embodiment of the present invention includes: a housing 10 and an electrode assembly 20.

[0032] Specifically, such as Figure 1 As shown, the housing 10 has a nursing surface 11; the electrode assembly 20 is at least partially disposed on the nursing surface 11. The electrode assembly 20 includes a first electrode plate 21 and a second electrode plate 22. The second electrode plate 22 is disposed on the outer periphery of the first electrode plate 21. The first electrode plate 21 extends in a ring shape along the circumferential direction of the nursing surface 11, and the second electrode plate 22 extends in an arc shape along the circumferential direction of the nursing surface 11.

[0033] In this embodiment, a nursing surface 11 is recessed on the side of the housing 10 away from the center of the nursing head 100 along the height direction of the nursing head 100, facing the center of the nursing head 100. The nursing surface 11 is suitable for contacting the nursing area, such as for the nursing of the human face. A first electrode plate 21 and a second electrode plate 22 are disposed on the nursing surface 11, and the surfaces of the first electrode plate 21 and the second electrode plate 22 away from the center of the nursing head 100 are flush with the nursing surface 11. The first electrode plate 21 is disposed at the center of the nursing surface 11, and the cross-sectional shape of the first electrode plate 21 is elliptical or circular. The second electrode plate 22 extends along the outer periphery of the nursing surface 11 and is disposed on the outer periphery of the first electrode plate 21, and the cross-sectional shape of the second electrode plate 22 is arc-shaped.

[0034] According to the embodiment of the present invention, the nursing head 100, by placing the first electrode plate 21 and the second electrode plate 22 on the nursing surface 11, can facilitate the nursing surface 11 to conform to the curvature contour of the human face, increase the contact area between the first electrode plate 21 and the second electrode plate 22 and the nursing area, and at the same time, the first electrode plate 21 is ring-shaped, which can better focus energy and facilitate better current transmission, thereby improving the working efficiency of the nursing head 100. The second electrode plate 22 can conform to the nasolabial folds of the face, which can facilitate the sliding use of the nursing head 100 at the nasolabial folds, thereby improving the working efficiency of the nursing head 100 and the deep nursing effect.

[0035] According to some embodiments of the present invention, the operating frequency of the first electrode plate 21 is f, where f satisfies: 0.5MHz≤f≤5MHz; the second electrode plate 22 is an EMS electrode.

[0036] When the frequency f of the first electrode 21 is less than 0.5MHz, the frequency f is too low to achieve high-frequency electrical pulses, and the effect of the first electrode 21 is not significant. When the frequency f of the first electrode 21 is greater than 5MHz, the frequency f is too high, which may cause excessive current to damage the skin of the treatment area, posing a safety hazard. For example, f=1MHz.

[0037] In this embodiment, the second electrode pad 22 is an EMS electrode. EMS is a technique that uses electrical current to stimulate muscles to achieve a specific effect. Small, low-voltage electrical pulses are delivered to the muscles through electrodes placed on the skin to cause muscle contraction.

[0038] Therefore, the frequency range of the first electrode 21 is limited, which increases the safety of using the nursing head 100 while giving full play to the function of the first electrode 21; the second electrode 22 is an EMS electrode, which can cause muscle contraction, tighten the skin, relax the body care area, minimize inflammation, prevent muscle atrophy, accelerate muscle healing, and stimulate muscle growth.

[0039] According to some embodiments of this utility model, such as Figure 1 As shown, there are multiple first electrode plates 21, which are arranged at radial intervals along the nursing surface 11.

[0040] That is, the cross-sectional shape of the multiple first electrode plates 21 is an elliptical ring or a circular ring, and the multiple first electrode plates 21 are respectively arranged radially at intervals at the center of the care surface 11. Thus, the multiple first electrode plates 21 are arranged radially at intervals along the care surface 11, which allows the energy generated by the first electrode plates 21 to be transferred to the deeper layers in a focused manner, improving the working efficiency of the care head 100. At the same time, it avoids the first electrode plates 21 releasing energy too densely, and avoids tip discharge when the care surface 11 is not in perfect contact with the human care area, thus avoiding burns to the human care area. This effectively improves the safety of the care head 100 and extends the service life of the care head 100.

[0041] According to some embodiments of this utility model, such as Figure 1 and Figure 5 As shown, the spacing between adjacent first electrode pieces 21 is equal, or the spacing between adjacent first electrode pieces 21 decreases radially along the nursing surface 11, or the spacing between adjacent first electrode pieces 21 increases radially along the nursing surface 11.

[0042] In this embodiment, the spacing between adjacent first electrode pads 21 is equal. Optionally, the spacing between adjacent first electrode pads 21 gradually decreases radially along the nursing surface 11, or the spacing between adjacent first electrode pads 21 gradually increases radially along the nursing surface 11.

[0043] Therefore, the spacing between adjacent first electrode pieces 21 can be selected according to different needs of the nursing head 100, so as to reasonably set multiple first electrode pieces 21 on the nursing head 100, which can increase the space utilization of the nursing surface 11, improve the versatility of the nursing head 100, reduce the processing accuracy of multiple first electrode pieces 21, and improve the processing efficiency of the nursing head 100.

[0044] According to some embodiments of this utility model, such as Figure 1 As shown, the widths of the multiple first electrode pieces 21 are equal, or the widths of the multiple first electrode pieces 21 tend to increase radially along the nursing surface 11, or the widths of the multiple first electrode pieces 21 tend to decrease radially along the nursing surface 11.

[0045] In this embodiment, the widths of adjacent first electrode pads 21 are equal. Optionally, the width of adjacent first electrode pads 21 gradually increases radially along the nursing surface 11, or the width of adjacent first electrode pads 21 gradually decreases radially along the nursing surface 11.

[0046] Therefore, the width of adjacent first electrode pieces 21 can be selected according to the different output power of the nursing head 100, so as to reasonably set multiple first electrode pieces 21 on the nursing head 100, which can increase the space utilization of the nursing surface 11, improve the versatility of the nursing head 100, reduce the processing accuracy of multiple first electrode pieces 21, and improve the processing efficiency of the nursing head 100.

[0047] According to some embodiments of this utility model, such as Figure 5 As shown, the distance between two adjacent first electrode plates 21 is L1, and L1 satisfies: 1.5mm≤L1≤3mm; the width of the first electrode plate 21 is L2, and L2 satisfies: 1mm≤L2≤10mm.

[0048] When the distance between two adjacent first electrode pads 21 is less than 1.5 mm, the distance is too small, which may cause the energy released by the two adjacent first electrode pads 21 to be too concentrated, potentially burning the area being treated. When the distance between two adjacent first electrode pads 21 is greater than 3 mm, the distance is too large, which may cause the energy released by the two adjacent first electrode pads 21 to be too dispersed, failing to achieve the desired treatment effect. For example, L1 = 2 mm.

[0049] When the width of the first electrode 21 is less than 1mm, the width of the first electrode 21 is too small, which may reduce the contact area between the first electrode 21 and the treatment area, thus reducing the output power of the treatment head 100. When the width of the first electrode 21 is greater than 10mm, the width of the first electrode 21 is too large, which may reduce the contact area between the second electrode 22 and the treatment area, thus making the working effect of the second electrode 22 insignificant. For example, L2 = 5mm.

[0050] Therefore, by limiting the distance range between two adjacent first electrode plates 21 and the width range of the first electrode plates 21, it is possible to effectively avoid the energy release of two adjacent first electrode plates 21 being too concentrated, thereby improving the safety of the nursing head 100. The contact area between the first electrode plate 21 and the second electrode plate 22 and the nursing site can be reasonably allocated according to actual needs, making full use of the space of the nursing surface 11, while increasing the output power of the nursing head 100, thereby improving the practicality and reliability of the nursing head 100.

[0051] According to some embodiments of this utility model, such as Figure 1 As shown, the electrode assembly 20 further includes a third electrode sheet 23, which is disposed in the central region of the first electrode sheet 21, and the distance between the third electrode sheet 23 and the adjacent first electrode sheet 21 is equal.

[0052] That is, the cross-sectional shape of the third electrode plate 23 is elliptical or circular, and the third electrode plate 23 is located at the center of the first electrode plate 21. At the same time, the distance between the third electrode plate 23 and the adjacent first electrode plate 21 along the radial direction of the nursing surface 11 is the same. Thus, the third electrode plate 23 is located in the central region of the first electrode plate 21, and the distance between the third electrode plate 23 and the adjacent first electrode plate 21 is equal, which can make the energy on the nursing surface 11 more focused, make full use of the available space of the nursing surface 11, increase the electrode area on the nursing surface 11, and improve the power of the nursing head 100.

[0053] According to some embodiments of the present invention, the sum of the areas of the positive and negative electrode plates included in the first electrode plate 21, the second electrode plate 22, and the third electrode plate 23 is equal; and / or, the sum of the areas of the plurality of electrode plates is S, where S satisfies: 1500mm²≤S≤3500mm²; and / or, the ratio range between the sum of the areas of the plurality of electrode plates S and the area S1 of the nursing surface 11 satisfies: 40%≤S / S1≤80%.

[0054] When the sum of the areas of multiple electrode pads is less than 1500 mm², the total area is relatively small, which may result in a smaller contact area between the electrode pads and the treated area, leading to lower output power of the treatment head 100. Conversely, when the sum of the areas of multiple electrode pads is greater than 3500 mm², the total area is relatively large, which may result in higher output power of the treatment head 100, potentially causing skin burns and increasing costs. For example, S = 2000 mm².

[0055] Optionally, when the ratio of the sum of the areas S of the multiple electrode pads to the area S1 of the care surface 11 is less than 40%, the space occupied by the multiple electrode pads on the care surface 11 is small, which may result in a lower output power of the care head 100. When the ratio of the sum of the areas S of the multiple electrode pads to the area S1 of the care surface 11 is greater than 80%, the space occupied by the electrode pads on the care surface 11 is large, which may result in a higher output power of the care head 100, making it easier to burn the skin and increasing costs. For example, S / S1 = 60%. Therefore, the sum of the areas of the positive and negative electrode pads included in the first electrode pad 21, the second electrode pad 22, and the third electrode pad 23 is equal, which can ensure that the multiple electrode pads output a stable frequency signal and improve the safety and reliability of the care head 100. Limiting the range of the sum of the areas of the multiple electrode pads and limiting the range of the ratio of the sum of the areas S of the multiple electrode pads to the area S1 of the care surface 11 maximizes the contact area between the multiple electrode pads and the care area while reducing the production cost and power consumption of the care head 100.

[0056] According to some embodiments of this utility model, the ratio of the area of ​​the first electrode 21 to the area of ​​the care surface 11 is in the range of 20%-40%; or, the ratio of the area of ​​the second electrode 22 to the area of ​​the care surface 11 is in the range of 20%-40%; or, the ratio of the area of ​​the first electrode 21 to the area of ​​the care surface 11 is in the range of 20%-40%, and the ratio of the area of ​​the second electrode 22 to the area of ​​the care surface 11 is in the range of 20%-40%; and / or, the ratio of the sum of the areas of the first electrode 21 to the sum of the areas of the second electrode 22 is in the range of 0.3-3.

[0057] Taking the first electrode pad 21 as an example, when the ratio of the area of ​​the first electrode pad 21 to the area of ​​the care surface 11 is less than 20%, the area of ​​the first electrode pad 21 is relatively small, which may result in a small output current and insignificant working effect. When the ratio of the area of ​​the first electrode pad 21 to the area of ​​the care surface 11 is greater than 40%, the area of ​​the first electrode pad 21 is relatively large, which may result in a large output current and potentially burn the skin. For example, the ratio of the area of ​​the first electrode pad 21 to the area of ​​the care surface 11 is 30%.

[0058] When the ratio of the sum of the areas of the first electrode 21 to the sum of the areas of the second electrode 22 is less than 0.3, the area of ​​the first electrode 21 is small and the area of ​​the second electrode 22 is large, which may result in a small output current from the first electrode 21 and the second electrode 22, making their working effect insignificant. When the ratio of the sum of the areas of the first electrode 21 to the sum of the areas of the second electrode 22 is greater than 3, the area of ​​the first electrode 21 is large and the area of ​​the second electrode 22 is small, resulting in a large output current from the first electrode 21 and the second electrode 22, which may burn the skin. For example, the ratio of the sum of the areas of the first electrode 21 to the sum of the areas of the second electrode 22 is 1. Therefore, by limiting the range of the ratio of the area of ​​the first electrode 21 to the area of ​​the nursing surface 11, the range of the ratio of the area of ​​the second electrode 22 to the area of ​​the nursing surface 11, and the range of the ratio of the sum of the areas of the first electrode 21 to the sum of the areas of the second electrode 22, the output power of the nursing head 100 can be reasonably controlled, thereby improving the working efficiency of the nursing head 100 while also enhancing its safety and reliability.

[0059] According to some embodiments of this utility model, such as Figure 2 and Figure 4 As shown, the nursing head 100 also includes a drive circuit board 30, which is disposed inside the housing 10 and is electrically connected to the electrode assembly 20.

[0060] That is, the drive circuit board 30 is located inside the housing 10 and is electrically connected to the electrode assembly 20. The drive circuit board 30 is suitable for controlling the operation of the electrode assembly 20. Thus, the drive circuit board 30 is located inside the housing 10 and electrically connected to the electrode assembly 20, which can improve the space utilization inside the housing 10, while shortening the connection path between the drive circuit board 30 and the electrode assembly 20, improving the electrical connection efficiency between the drive circuit board 30 and the electrode assembly 20, thereby improving the working efficiency of the nursing head 100.

[0061] According to the second aspect of the present invention, the beauty care device, such as Figure 3 As shown, the beauty care device includes: a care head 100 and a handle 40. The care head 100 is any of the care head 100 in the first aspect embodiment described above. The care head 100 is disposed on the handle 40, and a power supply and control circuit board is provided inside the handle 40. The power supply and control circuit board is electrically connected to the care head 100.

[0062] That is, the handle 40 is suitable for use in combination with the care head 100. The handle 40 is electrically connected to the care head 100 through a power supply and control circuit board. By using the beauty care device including the care head 100 and the handle 40, the beauty care device can be easily carried and used, effectively improving the user's skin care experience and skin care effect.

[0063] According to some embodiments of the present invention, the nursing head 100 and the handle 40 can be detachably coupled; or, the nursing head 100 and the handle 40 are an integral structural component.

[0064] In this embodiment, the care head 100 and the handle 40 can be detachably connected along the height direction of the care head 100, which facilitates the disassembly and installation of the beauty care equipment, as well as the replacement of care heads 100 with different functions, and also facilitates the maintenance and cleaning of the beauty care equipment.

[0065] Optionally, the care head 100 and handle 40 can be manufactured as a single piece, which simplifies the assembly process of the beauty care equipment, effectively improves the processing efficiency of the beauty care equipment, and at the same time improves the durability of the beauty care equipment and extends its service life.
