[0041] The embodiments of the present application will be described in detail below, and the embodiments described with reference to the drawings are exemplary, and the following description is made with reference to Figures 1-4 The care head 100 according to the embodiment of the present application is described, and the care head 100 comprises: a shell 10, an electrode assembly 20.
[0042] Specifically, as shown in Figures 1-3 The housing 10 has a first direction A and a second direction B, the first direction A and the second direction B are perpendicular, the length of the housing 10 in the first direction A is greater than the length of the second direction B, the housing 10 includes a care part 11, the care part 11 is formed with a care surface 111, the shape of the orthographic projection of the care surface 111 is the same as the shape of the orthographic projection of the shuttle shape; the electrode assembly 20 is at least partially arranged in the care part 11.
[0043] In the embodiment, the first direction A of the housing 10 is the length direction, the second direction B of the housing 10 is the width direction, and the first direction A and the second direction B are arranged vertically. The care part 11 for the user to care the skin is arranged on the housing 10, and the length of the care part 11 along the first direction A is greater than the length along the second direction B. The shape of the projection of the care part 11 formed along the center line direction of the housing 10 is a shuttle shape, which can be understood as a shape with two sharp ends and a wide middle. Among them, the shuttle refers to a tool for repeatedly pulling the weft (horizontal line) during weaving, which is similar to the shape of a jujube core, and the shuttle commonly used by people for fabrics is of this shape, so this shape is commonly called a shuttle shape. It can also be understood as the three-dimensional shape formed by combining two conical bodies with the bottom surface.
[0044] According to the care head 100 of the embodiment of the utility model, the length of the care part 11 of the care head 100 along the first direction A is greater than the length along the second direction B, so that the care part 11 is designed in a “shuttle shape” structure, and the end part along the first direction A is relatively sharp compared with the middle part when the care part 11 is used, which can facilitate the care of the eye and the fine parts such as the marionette lines; and the width of the middle area of the care part 11 along the first direction A in the second direction B is greater than the width of the two ends, the area of the electrode sheet is increased, the utilization rate of the space of the care part 11 is improved, the contact area with the skin is increased, and the rapid lifting effect is realized.
[0045] In some embodiments, in combination Figure 1 The care head 100 has a horizontal projection plane, and the projection shape of the care surface 111 on the horizontal projection plane includes: a first contour line 112 and a second contour line 113, the two ends of the first contour line 112 and the second contour line 113 are connected to each other, and the distance between the first contour line 112 and the second contour line 113 shows a decreasing trend from the center area to the edge area of the care surface 111 along the first direction A of the housing 10. Among them, the first contour line 112 and the second contour line 113 are smooth curves.
[0046] That is, the care part 11 is formed with a first contour line 112 and a second contour line 113 connected at two ends in a horizontal projection plane, the first contour line 112 and the second contour line 113 gradually decrease in distance between the two ends toward the two ends in the first direction A. Thus, the end of the care part 11 in the first direction A can achieve care of a subtle part compared to the central region of the care part 11, especially for the care of positions such as the corners of the eyes and the nasolabial folds, and the central region is wider to increase the contact area with the skin and improve the speed and efficiency of care.
[0047] In some embodiments, the first contour line 112 and the second contour line 113 are connected by a circular arc transition, so that the care part 11 can better fit the nasolabial folds when using the care head 100 to care for the nasolabial folds, and the care part 11 can achieve care of the nasolabial folds while avoiding the safety risks of the sharp end of the care part 11, increasing the safety of the use of the care head 100.
[0048] Optionally, the radius of curvature of the circular arc is R1, and the R1 satisfies: 4mm≤R1≤7mm. Thus, by limiting the radius of curvature of the circular arc at the connection between the first contour line 112 and the second contour line 113, the radius of curvature of the circular arc at the connection is smaller, so that the end of the care head 100 in the first direction A can better fit the care sites such as the nasolabial folds and the corners of the eyes, facilitating the lifting and tightening of the care head 100 on the wrinkle site, so that the care site is more comprehensive and has good applicability. At the same time, the end in the first direction A can be avoided to be relatively sharp, reducing the discomfort of using the care head 100.
[0049] In some embodiments, as shown in Figure 2 The care surface 111 includes a first care surface 114 and a second care surface 115, and the second care surface 115 is arranged on the outer circumferential side of the first care surface 114. The first care surface 114 and the second care surface 115 are arranged in the radial direction, wherein the first care surface 114 is arranged in the central region, the second care surface 115 is arranged on the outer circumferential side of the first care surface 114 adjacent to the first care surface 114, and the care part 11 at the junction of the first care surface 114 and the second care surface 115 is formed as a convex surface. In the direction from the first care surface 114 to the second care surface 115, the convex surface first protrudes away from the central region of the care part 11 and then recesses toward the central region of the care part 11, increasing the area of the care part 11 provided with the care surface 111, facilitating the arrangement of more electrode pieces on the care surface 111, and improving the efficiency of the care head 100.
[0050] That is, in the embodiment, the electrode assembly 20 includes a plurality of electrode pieces, at least one of the plurality of electrode pieces extending from the first care surface 114 to the second care surface 115. The electrode pieces extend from the first care surface 114 to the second care surface 115, which can facilitate increasing the contact area of the electrode pieces with the skin, so that the care head 100 is more closely attached to the skin. Among them, part of the plurality of electrode pieces is only arranged on the first care surface 114. The first care surface 114 is designed as a gently concave hyperboloid, and the central region of the hyperboloid is arranged adjacent to the center of the care part 11 compared with the edge region, that is, the first care surface 114 is concave to the center of the care part 11 to form a hyperboloid.
[0051] In some embodiments, the radius of curvature of the connection between the first care surface 114 and the second care surface 115 is R2, which satisfies: 10mm≤R2≤15mm. The radius of curvature of the circular arc at the connection between the two care surfaces 111 is limited, so that the first care surface 114 and the second care surface 115 can be in sufficient contact with the skin of the care site, increase the care area of the care head 100, and improve the care efficiency of the care head 100. Avoiding the radius of curvature of the connection between the two care surfaces 111 being too small, such as less than 10mm, which causes the first care surface 114 and the second care surface 115 to be unable to contact the skin at the same time, and the care efficiency is reduced. Or avoid the radius of curvature of the circular arc at the connection between the two care surfaces 111 being too large, such as greater than 15mm, which cannot guarantee that the care head 100 is in contact with multiple surfaces of the marionette lines when caring for the marionette lines, and the care efficiency is relatively low.
[0052] In some embodiments, as shown in Figure 1 and Figure 3 The care part 11 is formed with a protrusion 116, the protrusion 116 is arranged at the end of the care part 11 in the first direction A, the protrusion 116 away from the side surface of the central region of the shell 10 includes at least part of the first care surface 114 and part of the second care surface 115, and extends from the first care surface 114 to the second care surface 115. In the direction away from the shell 10 in the first direction A, the width of the protrusion 116 in the second direction B shows a decreasing trend.
[0053] In the embodiment, the care part 11 is formed with a protrusion 116, the protrusion 116 is arranged at the end of the care part 11 along the first direction A, the surface of the protrusion 116 includes a part of the first care surface 114 and a part of the second care surface 115, at least one electrode sheet is arranged at the position of the protrusion 116 and extends along the first care surface 114 to the second care surface 115, the protrusion 116 is located at the highest point of the care part 11 along the center line direction of the care part 11. The protrusion 116 has a decreasing trend as a whole along the first direction A towards the end, the contour line formed by the protrusion 116 in the horizontal projection plane is an arc line, and the part of the first care surface 114 arranged on the protrusion 116 gradually extends upwardly along the first direction A towards the direction away from the shell 10, and then extends downwardly, and the part of the second care surface 115 is located on the surface of the protrusion 116 extending downwardly. The protrusion 116 includes a first surface located at the first care surface 114 and a second surface located at the second care surface 115, the curvature radius of the first surface is greater than that of the second surface, which is helpful for the care of the fine parts and makes the care head 100 more fit the skin.
[0054] Therefore, the care part 11 is formed with the protrusion 116, which is convenient for the care of the fine parts, the use of the muscle care head 100 at the positions such as the corners of the eyes or the nasolabial lines, so as to increase the care function and the care range of the care head 100 and improve the care effect of the care head 100.
[0055] In some embodiments, as shown in Figure 1 The plurality of electrode sheets includes a first electrode sheet 21 arranged on one side surface of the protrusion 116 away from the central area of the shell 10, and the first electrode sheet 21 is matched with the one side surface of the protrusion 116. That is, the first electrode sheet 21 is arranged at the position of the protrusion 116, the first electrode sheet 21 is fit with the surface of the protrusion 116 and extends along the surface of the protrusion 116, that is, the first electrode sheet 21 extends from the first care surface 114 to the second care surface 115. The arrangement of the first electrode sheet 21 at the position of the protrusion 116 is convenient for the care of the positions such as the eyes, the nose and the mouth, which is helpful for the fit of the first electrode sheet 21 with the skin and improves the care effect of the care head 100.
[0056] Optionally, in combination with Figure 2The plurality of electrode pieces include: a second electrode piece 22, the second electrode piece 22 is arranged on both sides of the care part 11 of the care surface 111 along the second direction B, and the second electrode piece 22 extends from the first care surface 114 to the second care surface 115. In this embodiment, there are two second electrode pieces 22, and the two second electrode pieces 22 are arranged on both sides of the care part 11 along the second direction B and extend from the first care surface 114 to the second care surface 115. When the care head 100 is used, the second electrode piece 22 can realize the care of both sides of the crows' feet, and because the surface of the second electrode piece 22 adhering to the care part 11 is a circular arc, the second electrode piece 22 is easy to adhere to the skin, the care effect is more amazing, and it is helpful for the sliding of the care head 100 in the fine part. Therefore, the position of the second electrode piece 22 can facilitate the care of the eye and the fine part such as the crows' feet, improve the adhesion of the care head 100 to the corresponding part, facilitate the realization of all-around care, and the care part 11 is more comprehensive.
[0057] In some embodiments, the second electrode piece 22 extends along the first direction A, and the width of the second electrode piece 22 in the second direction B decreases from the middle to the two ends of the second electrode piece 22. That is, for the second electrode piece 22 arranged on both sides of the care part 11, the second electrode piece 22 extends along the first direction A, and the width of the second electrode piece 22 gradually decreases in the direction towards and away from the first electrode piece 21. The width of the middle region of the second electrode piece 22 is greater than the width of the two end regions. Therefore, when the second electrode piece 22 is arranged, the shape of the care surface 111 is fully utilized to increase the area arranged on the care surface 111, which on the one hand facilitates the increase of the care surface 111 of the care head 100, improves the care efficiency, and at the same time, the area of the second electrode piece 22 is increased, the power of the second electrode piece 22 is improved, and the rapid care of the corresponding skin part is realized.
[0058] In some embodiments, as shown in Figure 1 and Figure 2 , the plurality of electrode pieces include: a third electrode piece 23, the third electrode piece 23 is arranged on the first care surface 114 and is distributed between the second electrode pieces 22, and the third electrode piece 23 is matched with the first care surface 114. The third electrode piece 23 is arranged between the two second electrode pieces 22 distributed along the second direction B, and the third electrode piece 23 is located on the first care surface 114 and extends on the surface of the first care surface 114. Therefore, the arrangement of the third electrode piece 23 facilitates the care of the adhering part by the first care surface 114, the care area is larger, and the care efficiency is improved.
[0059] In some embodiments, the third electrode sheet 23 is a plurality of third electrode sheets 23, the plurality of third electrode sheets 23 are arranged along the radial direction of the first care surface 114, and each of the third electrode sheets 23 extends along the circumferential direction of the first care surface 114. That is, the third electrode sheet 23 is annular, and the plurality of third electrode sheets 23 are arranged along the radial direction of the first care surface 114, that is, at least along the first direction A and the second direction B, and the polarities of adjacent two third electrode sheets 23 are opposite. The area of the region of the third electrode sheet 23 at the end along the first direction A is greater than the area of the region at the middle, so that the third electrode sheet 23 can make full use of the shuttle-shaped care part 11, improve the power of the first care surface 114, and realize full use of the first care surface 114, increase the proportion of the third electrode sheet 23 to the area of the first care surface 114, and increase the efficiency of use and the lifting effect on the skin.
[0060] In some embodiments, the electrode assembly 20 comprises: the first electrode sheet 21, the second electrode sheet 22, and the third electrode sheet 23, the first electrode sheet 21 is arranged at least at one end of the care part 11 along the first direction A, and the first electrode sheet 21 extends from the first care surface 114 to the second care surface 115; the second electrode sheet 22 is arranged on both sides of the care part 11 along the second direction B, the first electrode sheet 21 is arranged between adjacent two second electrode sheets 22, and the second electrode sheet 22 extends from the first care surface 114 to the second care surface 115; and the third electrode sheet 23 is arranged on the first care surface 114, and the third electrode sheet 23 is adapted to the shape of the first care surface 114.

The polarities of the two second electrode sheets 22 are opposite, and the polarities of adjacent two third electrode sheets 23 are opposite. The first electrode sheet 21 is suitable for the care of fine parts such as the eye and the nasolabial fold, and the third electrode sheet 23 is suitable for the care of large parts of the face such as the cheek and the forehead.
[0062] The area of the first electrode sheet 21 is S1, and S1 satisfies: 150mm 2 ≤ S1 ≤ 200mm 2 ; and / or,
