[0036] The embodiments of this utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figures 1-5 The present invention describes a care head 100 according to an embodiment of the present invention. The care head 100 is adapted to be used in conjunction with a beauty handle 50. The care head 100 includes a housing 10, an electrode assembly 20, and a drive circuit board 30.

[0037] Specifically, such as Figure 1 As shown, the housing 10 includes a nursing section 11, which has a nursing surface 111; the electrode assembly 20 includes a first electrode 21, which is disposed on the nursing section 11; the drive circuit board 30 is disposed inside the housing 10, and the electrode assembly 20 is electrically connected to the drive circuit board 30; wherein, the first electrode 21 is a flat electrode, which is flush with the nursing surface 111, or the first electrode 21 is at least partially disposed below the nursing surface 111.

[0038] In this embodiment, the housing 10 has a nursing section 11, on which a nursing surface 111 is formed. A first electrode 21 is provided in the central region of the nursing surface 111. The first electrode 21 is a flat electrode, that is, the first electrode 21 has a sheet-like or block-like structure. The first electrode 21 is disposed on the surface of the nursing section 11, and the side of the first electrode 21 away from the center of the housing 10 is flush with the nursing surface 111, or partially disposed below the nursing surface 111. For example, the side of the first electrode 21 away from the center of the housing 10 is a plane, and the plane is flush with the nursing surface 111; or, for example, the position of the conductive contact 212 on the first electrode 21 is disposed below the nursing surface 111, and the other parts are flush with the nursing surface 111. Or the first electrode 21 is entirely disposed below the nursing surface 111. A drive circuit board 30 is disposed inside the housing 10, and the electrode assembly 20 is electrically connected to the drive circuit board 30 to control the operation of the electrode assembly 20.

[0039] According to the embodiment of the present invention, the nursing head 100, by placing the first electrode 21 on the nursing part 11, with the first electrode 21 flush with the nursing surface 111, or with the first electrode 21 at least partially lower than the nursing surface 111, facilitates the output of high-frequency electrical pulses by the first electrode 21, achieving the effects of lifting, tightening, and reducing wrinkles on the skin. At the same time, it facilitates the integration of the first electrode 21 into the housing 10, improving the integration and space utilization of the nursing head 100, avoiding scratches caused by external structural components to the first electrode 21, effectively extending the service life of the first electrode 21, improving the reliability of the nursing head 100, and avoiding the electrode assembly 20 protruding from the nursing part 11, which would result in poor adhesion to the skin, increasing the contact area with the skin, improving efficiency, and enhancing the user experience.

[0040] According to some embodiments of this utility model, such as Figure 5 As shown, a mounting hole is formed on the nursing part 11, which penetrates the nursing surface 111, and the electrode assembly 20 is fitted into the mounting hole; along the direction perpendicular to the first electrode 21, the height difference between the nursing surface 111 and the first electrode 21 is H, and H satisfies: 0≤H≤3mm.

[0041] In this embodiment, the nursing surface 11 has multiple mounting holes, including a first mounting hole. The first mounting hole is located near the center of the nursing surface 111, and the first electrode 21 is disposed within the first mounting hole. When the height difference between the nursing surface 111 and the first electrode 21 is greater than 3mm, the height difference is too large, which may result in a small contact area between the first electrode 21 and the skin, leading to an unsatisfactory nursing effect. Simultaneously, it may cause the first electrode 21 to occupy too much internal space in the housing 10, affecting the internal structural components of the housing 10. When the height difference between the nursing surface 111 and the first electrode 21 is less than 3mm, the height difference is too small, affecting the contact effect between the first electrode 21 and the skin. It may also cause the distance between the first electrode 21 and the drive circuit board 30 to be too large, hindering the electrical connection between the first electrode 21 and the drive circuit board 30. For example, H = 2mm.

[0042] Therefore, the range of the height difference between the care surface 111 and the first electrode 21 is limited to ensure the normal operation of the first electrode 21, ensure the skin contact effect, protect the first electrode 21 from being scratched by external structural components, facilitate the cleaning and maintenance of the first electrode 21, facilitate effective electrical connection between the first electrode 21 and the drive circuit board 30, and improve the space utilization rate inside the housing 10 and improve the compactness of the care head 100 structure.

[0043] According to some embodiments of this utility model, such as Figure 1 As shown, the first electrode 21 includes: a substrate 211, on the working surface of the substrate 211 are a plurality of conductive contacts 212 arranged in an array on the substrate 211; the plurality of conductive contacts 212 are flush with the working surface of the substrate 211; or, a plurality of grooves are formed on the working surface, and the plurality of conductive contacts 212 are disposed in the plurality of grooves. Alternatively, the plurality of conductive contacts 212 disposed on the substrate 211 are partially flush with the working surface of the substrate 211 and partially lower than the working surface of the substrate 211.

[0044] In this embodiment, the substrate 211 is disc-shaped. The substrate 211 is disposed in the first mounting hole and the outer periphery of the substrate 211 contacts the side wall of the first mounting hole and achieves a fit with the first mounting hole. A working surface is formed on the side of the substrate 211 away from the nursing part 11 along the height direction of the nursing head 100. A plurality of conductive contacts 212 are arranged alternately on the working surface, and the plurality of conductive contacts 212 are flush with the working surface along the height direction of the nursing head 100.

[0045] Optionally, in this embodiment, a plurality of alternately arranged grooves may be formed on the working surface of the substrate 211, and the plurality of grooves are suitable for setting a plurality of conductive contacts 212.

[0046] Therefore, the working surface of the substrate 211 is provided with multiple conductive contacts 212, which are arranged in an array on the substrate 211 and are flush with the working surface of the substrate 211; or multiple grooves are formed on the working surface, and the multiple conductive contacts 212 are disposed in the multiple grooves. The positions of the conductive contacts 212 can be corresponding to the arrangement of the substrate 211, which facilitates the connection between the drive circuit board 30 inside the housing 10 and the multiple conductive contacts 212, improves the power of the care head 100, and facilitates the integration of the multiple conductive contacts 212 onto the care head 100, improving the integration of the care head 100. At the same time, the design of multiple conductive contacts 212 can increase the current density, resulting in a faster heating rate, which is beneficial for promoting collagen regeneration and facilitating the repair of pores and scars.

[0047] According to some embodiments of this utility model, such as Figure 1 As shown, the first electrode 21 includes a first electrode portion 22 and a second electrode portion 23. The first electrode portion 22 includes a plurality of conductive contacts 212, and the plurality of conductive contacts 212 in the first electrode portion 22 have the same polarity. The second electrode portion 23 includes a plurality of conductive contacts 212, and the plurality of conductive contacts 212 in the second electrode portion 23 have the same polarity. The polarities of the first electrode portion 22 and the second electrode portion 23 are opposite.

[0048] In this embodiment, the first electrode 21 includes a plurality of first electrode portions 22 and a plurality of second electrode portions 23. The conductive contacts 212 in each first electrode portion 22 and each second electrode portion 23 have the same polarity. The plurality of first electrode portions 22 and the plurality of second electrode portions 23 are alternately arranged along the radial direction of the substrate 211. Optionally, the number of first electrode portions 22 and second electrode portions 23 is even.

[0049] Therefore, the multiple conductive contacts 212 in the first electrode portion 22 have the same polarity, and the multiple conductive contacts 212 in the second electrode portion 23 have the same polarity, which can increase the power on the first electrode portion 22 and the second electrode portion 23, effectively improving the working efficiency of the nursing head 100. At the same time, the first electrode portion 22 and the second electrode portion 23 have opposite polarities, which facilitates the distribution of conductive contacts 212 on the substrate 211. The alternating arrangement of the first electrode portion 22 and the second electrode portion 23 can facilitate the formation of a circuit between the conductive contacts 212, shorten the circuit, and improve the working efficiency of the first electrode 21.

[0050] According to some embodiments of this utility model, such as Figure 1As shown, the first electrode portion 22 and the second electrode portion 23 both extend circumferentially along the first electrode 21, and multiple first electrode portions 22 and multiple second electrode portions 23 are alternately arranged radially along the first electrode 21; or, the first electrode portion 22 and the second electrode portion 23 both extend along the first direction A of the first electrode 21, and multiple first electrode portions 22 and multiple second electrode portions 23 are alternately arranged along the second direction B of the first electrode 21; or, a portion of the first electrode 21 and a portion of the second electrode 24 extend circumferentially and are distributed radially, while a portion of the first electrode 21 and a portion of the second electrode 24 extend along the first direction A and / or the second direction B, and are staggered with the circumferentially extended first electrode 21 and second electrode 24, with the first direction A and the second direction B being orthogonal.

[0051] In this embodiment, the first electrode portion 22 extends circumferentially along the first electrode 21, and the second electrode portion 23 extends circumferentially along the first electrode 21. The first electrode portion 22 and the second electrode portion 23 are alternately arranged radially along the working surface. Both the first electrode portion 22 and the second electrode portion 23 are annular electrodes, and multiple first electrode portions 22 and multiple second electrode portions 23 are alternately arranged radially along the first electrode 21. Optionally, multiple first electrode portions 22 extend circumferentially along the first electrode 21 and are spaced apart, and multiple second electrode portions 23 extend circumferentially along the first electrode 21 and are spaced apart. In this case, the first electrode portion 22 and the second electrode portion 23 are arranged in an arc shape.

[0052] Therefore, the arrangement and position of the first electrode 22 and the second electrode 23 can be selected according to the function that the nursing head 100 needs to perform, so as to reasonably set the position of multiple conductive contacts 212, increase the utilization rate of the substrate 211, facilitate the first electrode 21 to present various shapes and layouts, and improve the arrangement density of multiple conductive contacts 212.

[0053] According to some embodiments of the present invention, the distance between adjacent first pole portion 22 and second pole portion 23 is L1, and L1 satisfies: 0.5mm≤L1≤4mm.

[0054] When the distance between adjacent first electrode portions 22 and second electrode portions 23 is less than 0.5 mm, the distance is too small, which may cause a short circuit between the first electrode portions 22 and second electrode portions 23. When the distance between adjacent first electrode portions 22 and second electrode portions 23 is greater than 4 mm, the distance is too large, which may result in too few first electrode portions 22 and second electrode portions 23 arranged on the working surface, reducing the working efficiency of the nursing head 100. In this embodiment, L1 is preferably 1 mm to 3 mm, specifically 2 mm.

[0055] The distance between two adjacent conductive contacts 212 on the first electrode 22 is L2, where L2 satisfies: 0.3mm ≤ L2 ≤ 5mm; or, the distance between two adjacent conductive contacts 212 on the second electrode 23 is L3, where L3 satisfies: 0.3mm ≤ L3 ≤ 5mm. Or, the distance between two adjacent conductive contacts 212 on both the first electrode 22 and the second electrode 23 satisfies 0.3mm-5mm.

[0056] When the distance between two adjacent conductive contacts 212 on the first electrode 22 is less than 0.3 mm, the distance between the two adjacent conductive contacts 212 on the first electrode 22 is too small, which may result in a large number of conductive contacts 212 on the first electrode 22, increasing costs. When the distance between two adjacent conductive contacts 212 on the first electrode 22 is greater than 5 mm, the distance between the two adjacent conductive contacts 212 on the first electrode 22 is too large, which may result in a small number of conductive contacts 212 on the first electrode 22, reducing the power of the first electrode 22. In this embodiment, L2 is preferably 0.5 mm to 3.5 mm, specifically 2 mm.

[0057] When the distance between two adjacent conductive contacts 212 on the second electrode 23 is less than 0.3 mm, the distance between the two adjacent conductive contacts 212 on the second electrode 23 is too small, which may result in a large number of conductive contacts 212 on the second electrode 23, increasing costs. When the distance between two adjacent conductive contacts 212 on the second electrode 23 is greater than 5 mm, the distance between the two adjacent conductive contacts 212 on the second electrode 23 is too large, which may result in a small number of conductive contacts 212 on the second electrode 23, reducing the power of the second electrode 23. In this embodiment, L3 is preferably 0.5 mm to 3.5 mm.

[0058] The diameter of each conductive contact 212 is D, where D satisfies: 0.5mm ≤ D ≤ 5mm. When the diameter of each conductive contact 212 is less than 0.5mm, the diameter of each conductive contact 212 is too small, resulting in an excessively high density of conductive contacts 212 on the substrate 211, increasing the number of processing steps and costs. When the diameter of each conductive contact 212 is greater than 5mm, the diameter of each conductive contact 212 is too large, making it impossible to guarantee the safety of the placement of the conductive contacts 212 used as positive and negative electrodes, or resulting in a low distribution density of conductive contacts 212, reducing power and affecting the nursing effect and speed. For example, D = 3mm.

[0059] The total area of ​​the multiple conductive contacts 212 is S, which satisfies: 50mm² ≤ S ≤ 190mm². When the total area of ​​the multiple conductive contacts 212 is less than 50mm², the total area is too small, which may result in insufficient power of the first electrode 22 and the second electrode 23. When the total area of ​​the multiple conductive contacts 212 is greater than 190mm², the total area is too large, increasing the cost. For example, S = 100mm².

[0060] Therefore, by limiting the spacing range between adjacent first pole portions 22 and second pole portions 23, the spacing range between two adjacent conductive contacts 212 on the first pole portions 22 and second pole portions 23, the diameter range of each conductive contact 212, and the total area range of multiple conductive contacts 212, the safety and reliability of the nursing head 100 can be improved, while reducing costs and increasing the working efficiency of the nursing head 100.

[0061] According to some embodiments of this utility model, such as Figure 1 As shown, the electrode assembly 20 includes: a second electrode 24, which is disposed on the outer periphery of the first electrode 21, is electrically connected to the drive circuit board 30, is disposed on the nursing section 11, and at least a portion of the second electrode 24 is exposed on the nursing surface 111; or, the second electrode 24 is a strip electrode.

[0062] In this embodiment, the plurality of mounting holes includes a plurality of second mounting holes, which are formed on the nursing part 11 and located on the outer periphery of the first mounting hole, and are spaced apart circumferentially. A plurality of second electrodes 24 are respectively fitted into the plurality of second mounting holes, and the surface of the second electrode 24 away from the center of the housing 10 is flush with the nursing surface 111. In this embodiment, the second electrode 24 is a strip electrode and extends circumferentially along the first electrode 21. The second electrode 24 is electrically connected to a drive circuit board 30 disposed within the housing 10, and the drive circuit board 30 controls the operation of the second electrode 24. A plug-in terminal is provided on the side of the electrode assembly 20 away from the nursing surface 111. The electrode assembly 20 is electrically connected to the drive circuit board 30 by plugging into the plug-in terminal, which is convenient and improves assembly efficiency.

[0063] Therefore, the second electrode 24 is disposed on the outer periphery of the first electrode 21, the second electrode 24 is electrically connected to the drive circuit board 30, and at least a portion of the second electrode 24 is exposed on the nursing surface 111; or the second electrode 24 is a strip electrode, which can increase the current density of the nursing head 100 and the contact area with the nursing part 111, thereby increasing the output power of the nursing head 100.

[0064] According to some embodiments of this utility model, such as Figure 1As shown, the number of second electrodes 24 is even, and the polarities of adjacent second electrodes 24 are the same, while the polarities of two oppositely arranged second electrodes 24 are opposite; or, the polarities of two adjacent second electrodes 24 are opposite, while the polarities of two oppositely arranged second electrodes 24 are the same.

[0065] For example, a plurality of second electrodes 24 are arranged at intervals along the circumference of the first electrode 21, and two adjacent second electrodes 24 along the circumference of the first electrode 21 have the same polarity, while two second electrodes 24 arranged opposite to each other along the radial direction of the first electrode 21 have opposite polarities. Optionally, two adjacent second electrodes 24 along the circumference of the first electrode 21 have opposite polarities, while two second electrodes arranged opposite to each other along the radial direction of the first electrode 21 have the same polarity.

[0066] Therefore, among the multiple second electrodes 24, adjacent second electrodes 24 have the same polarity, and two opposite second electrodes 24 have opposite polarities; or two adjacent second electrodes 24 have opposite polarities, and two opposite second electrodes 24 have the same polarity. The two adjacent second electrodes 24 or the two opposite second electrodes 24 can easily realize a current loop, improve efficiency, and increase the care area of ​​the second electrodes 24.

[0067] According to some embodiments of the present invention, the frequency of the first electrode 21 is greater than or equal to the frequency of the second electrode 24.

[0068] In this embodiment, the first electrode 21 is adapted to apply high-frequency electrical pulses, and the second electrode 24 is adapted to apply EMS. Thus, the frequency of the first electrode 21 is greater than or equal to the frequency of the second electrode 24. When the nursing head 100 is working, the first electrode 21 and the second electrode 24 work together to periodically stimulate the muscles using high-frequency and low-frequency currents, which can lift and tighten the skin and reduce edema.

[0069] According to some embodiments of the present invention, the frequency f of the first electrode 21 satisfies: 0.5MHz≤f≤5MHz; the second electrode 24 is an EMS electrode.

[0070] When the frequency f of the first electrode 21 is less than 0.5MHz, the frequency f is too low to achieve high-frequency 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.

[0071] In this embodiment, the second electrode 24 is an EMS electrode. EMS is a technique that uses electrical current to stimulate muscles to achieve specific effects. Small, low-voltage electrical pulses are delivered to the muscles through electrodes placed on the skin to cause muscle contraction.

[0072] Therefore, the frequency range of the first electrode 21 and the second electrode 24 is limited, which increases the safety of using the care head 100 while giving full play to the function of the first electrode 21. The second electrode 24 is an EMS electrode, which provides small, low-voltage electrical pulses to the muscles to output microcurrents, so as to cause the muscles to contract and tighten the skin.

[0073] According to some embodiments of this utility model, such as Figure 2 and Figure 4 As shown, the nursing head 100 also includes a phototherapy component 40, which is disposed inside the housing 10 and is electrically connected to the drive circuit board 30; wherein, a light-transmitting part is formed on the housing 10, and the phototherapy component 40 is opposite to the light-transmitting part.

[0074] In this embodiment, the phototherapy component 40 is disposed within the housing 10, which includes a first housing 12 and a second housing 13. The phototherapy component 40 and the drive circuit board 30 are all disposed within the space defined by the first housing 12 and the second housing 13. The first housing 12 is formed as a light-transmitting part, and the electrode assembly 20 is disposed on the first housing 12. The phototherapy component 40 is adapted to generate electricity and produce light waves through the drive circuit board 30, and the light-transmitting part is adapted to transmit and penetrate the light waves through the housing 10. The phototherapy component 40 can adjust its color according to the care mode or intensity, so that the user can more intuitively understand the current mode of the care head 100.

[0075] Therefore, the phototherapy component 40 is disposed inside the housing 10 and is electrically connected to the drive circuit board 30. A light-transmitting part is formed on the housing 10, and the phototherapy component 40 is opposite to the light-transmitting part.
