Description

Technical Field

[0001] The present application relates to the technical field of skin treatment, and in particular to an electrode head and a skin treatment device. Background Art

[0002] Skin treatment devices, such as radio frequency beauty devices, use radio frequency as a non-invasive technical means to achieve skin remodeling, with the technical advantages of short treatment recovery period, few side effects, and safe and controllable energy. When radio frequency current flows through the skin tissue, an oscillating current is generated, driving the charged particles or charges between the radio frequency electrodes to produce rapid back and forth vibrations along the direction of the power lines. The heat energy generated by the friction between the particles acts on the target tissue skin tissue as bio-impedance to produce a thermal effect, thereby promoting the initial denaturation and contraction of collagen. Over time, collagen remodeling occurs through a controlled wound healing response and related new collagen formation, and ends with tighter skin. Secondly, users can also apply essence to the skin so that the skin treatment device can promote the skin's absorption of the essence through the electrode head.

[0003] However, the electrodes of the electrode head in the related art are generally arranged in a dot matrix, which makes the area of interaction between the electrode head and the skin small, and the assembly process of this dot matrix electrode head is relatively complicated, while increasing the risk of essence entering the shell through the electrode head.

DETAILED DESCRIPTION

[0029] In order to enable those skilled in the art to better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of the utility model.

[0030] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the utility model.

[0031] See also Figure 1 The present invention provides a skin treatment device 10, which may include a main unit 30 and an electrode head 20. The electrode head 20 may be mounted on the main unit 30. The main unit 30 may transmit microcurrent to the skin through the electrode head 20, thereby achieving a relatively good skin tightening effect.

[0032] The specific structure of the electrode head 20 can refer to the following embodiments. Since the skin treatment device 10 adopts all the technical solutions of all the following embodiments, it has at least all the beneficial effects brought by the technical solutions of the following embodiments, which will not be described one by one here.

[0033] See also Figure 2The embodiment of the present invention also provides an electrode head 20. The electrode head 20 may include a shell 100, a light-transmitting member 200, and a plurality of electrodes 300. The light-transmitting member 200 is mounted on the shell 100. The light-transmitting member 200 has a light-emitting surface 210. The light-transmitting member 200 is used to contact the skin. The plurality of electrodes 300 may be connected to the shell 100 and arranged in an extended shape on the light-emitting surface 210. The plurality of electrodes 300 are arranged in sequence around the edge of the light-transmitting member 200. Thus, compared with the electrode head 20 in the related art, the present application helps to increase the area of interaction between the plurality of electrodes 300 and the skin by connecting the plurality of electrodes 300 to the shell 100 and extending the light-emitting surface 210, and arranging the plurality of electrodes 300 in sequence around the edge of the light-transmitting member 200. This helps to improve the efficiency of current transmission between the two interacting electrodes 300, and further helps to improve the cosmetic effect of the electrode head 20.

[0034] In addition, the structure of the electrode head 20 of the present application is more streamlined, making the assembly process of the electrode head 20 more convenient. At the same time, there are fewer connection gaps between the various parts, making the connection between the electrode 300 and the shell 100 and the light-transmitting member 211 tighter, reducing the risk of essence leaking into the shell 100 of the electrode head 20.

[0035] Secondly, because the electrodes 300 are arranged in an extended shape on the light-emitting surface 210, when the electrode head 20 releases a weak current, the energy can be more evenly applied to the skin, avoiding the problem of excessive energy concentration or uneven energy distribution, thereby improving the uniformity and consistency of the cosmetic effect. Furthermore, the multiple electrodes 300 are located at the edge of the light-transmitting member 200, which helps reduce the risk of multiple electrodes 300 blocking the light-transmitting member 200.

[0036] It is understandable that the electrode 300 can directly contact the user's skin, so that the electrode 300 can conduct microcurrent to the skin to lift and tighten the user's skin; or, the user can apply essence on the skin, so that the electrode 300 can conduct microcurrent to the skin through the essence to lift and tighten the user's skin and promote the user's skin's absorption of the essence. Of course, the electrode 300 is arranged in an extended shape on the light-emitting surface 210, that is, the overall outer contour of the electrode 300 on the light-emitting surface 210 can be arranged in an arc shape; or, the overall outer contour of the electrode 300 on the light-emitting surface 210 can be arranged in a plate shape; or, the overall outer contour of the electrode 300 on the light-emitting surface 210 can be arranged in a spiral shape.

[0037] See also Figures 1 to 4The light-transmitting member 200 may be made of sapphire, optical glass or ceramic material, etc. The light-transmitting member 200 may be arranged in a plate shape, and the light-emitting surface 210 of the light-transmitting member 200 may be located on the side of the light-transmitting member 200 away from the host 30. A laser may be provided inside the host 30. The light-transmitting member 200 may filter the light emitted by the host 30, thereby selecting appropriate light to act on the user's skin to achieve a beauty effect.

[0038] In some embodiments, the light-emitting surface 210 may include a light-transmitting area 211 and a mounting area 212 connected to each other. The mounting area 212 may be arranged around the edge of the light-transmitting area 211. Multiple electrodes 300 may be mounted in the mounting area 212. Each electrode 300 may protrude from the light-transmitting area 211 toward the mounting area 212. Specifically, the light-emitting surface 210 may be divided into the light-transmitting area 211 and the mounting area 212. The light-transmitting area 211 may be located in the center of the entire light-emitting surface 210. The mounting area 212 may be provided for the installation of the electrodes 300. The light-transmitting area 211 may filter the light emitted by the host 30. In this way, each electrode 300 may protrude from the light-transmitting area 211 toward the mounting area 212, which further helps to reduce the risk of the electrode 300 blocking the light-transmitting area 211.

[0039] See also Figures 2 to 6 In some embodiments, each electrode 300 can extend along an arc path, that is, the overall outer contour of each electrode 300 can be roughly arc-shaped, thereby helping the shape of the electrode 300 to better adapt to or fit the natural curve of the skin, thereby further helping to increase the area of interaction between multiple electrodes 300 and the skin.

[0040] The electrode 300 may have a convex side 310 and a concave side 320 facing each other, the convex side 310 may face away from the light-transmitting area 211, and the concave side 320 may face the light-transmitting area 211. Specifically, the electrode 300 has a convex side 310 and a concave side 320 facing each other along its width direction, the convex side 310 may be the side of the electrode 300 having an outer arc contour, and the concave side 320 may be the side of the electrode 300 having an inner arc contour, and the radius of the circle corresponding to the outer contour of the electrode 300 may be greater than the radius of the circle corresponding to the inner contour of the electrode 300. In this way, since the convex side 310 is set away from the light-transmitting area 211 and the concave side 320 is set towards the light-transmitting area 211, the electrode 300 can be reasonably installed on the light-emitting surface 210, thereby helping to reduce the risk of the electrode 300 blocking the light-transmitting area 211.

[0041] In some embodiments, the cross-sectional area of the electrode 300 can gradually increase along the arc path, so that the cross-sectional area of the electrode 300 gradually widens from one end to the other, thereby facilitating providing more contact area at the wider end of the electrode 300, thereby achieving a stronger current transfer effect at the wider end of the electrode 300.

[0042] In addition, since the skin curvature and sensitivity of different parts of the human body are different, the gradually changing cross-sectional area design enables the electrode head 20 to better adapt to the characteristics of different skin areas, providing a more fitting and comfortable treatment experience.

[0043] See also Figure 2 In some embodiments, the electrode 300 can be attached to the light emitting surface 210 and the end surface of the shell 100. Specifically, when the electrode 300 is tightly attached to the light emitting surface 210 and the end surface of the shell 100, the light emitting surface 210 and the end surface of the shell 100 can be roughly on the same plane, which helps to achieve a smooth transition at the connection between the light emitting surface 210 and the end surface of the shell 100, and there are no obvious protrusions or gaps. The connection between the light emitting surface 210 and the end surface of the shell 100 will not scratch the skin as easily as a sharp edge, thereby helping to reduce the risk of the connection between the light emitting surface 210 and the end surface of the shell 100 scratching the user's skin. In addition, the electrode 300 is arranged in an extended shape, so that the electrode 300 has a larger surface area, which helps to shield the connection between the light-transmitting member 200 and the shell 100, thereby helping to reduce the risk of essence entering through the connection between the light-transmitting member 200 and the shell 100.

[0044] In some embodiments, the electrode 300 protrudes relative to the light emitting surface 210, and the protruding height of the electrode 300 relative to the light emitting surface 210 is 0.5 mm to 5 mm, wherein the protruding height of the electrode 300 relative to the light emitting surface 210 can be, but is not limited to, 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, or 5 mm. In this way, the protrusion of the electrode 300 relative to the light emitting surface 210 helps to increase the contact area between the electrode 300 and the skin, thereby helping the current generated by the electrode 300 to be more evenly transmitted to the skin. In addition, the protruding height of the electrode 300 relative to the light emitting surface 210 within the above-mentioned range helps to reduce the abruptness of the electrode 300 relative to the light emitting surface 210, so that the electrode 300 and the light emitting surface 210 can better fit the user's skin.

[0045] See also Figure 5 and Figure 7In some embodiments, the housing 100 may be provided with a plurality of first fixing portions 110, each of which may correspond to a plurality of electrodes 300. Each electrode 300 may be provided with a second fixing portion 330, and the second fixing portion 330 of each electrode 300 may be fixedly matched with the corresponding first fixing portion 110. Specifically, when fixing the electrode 300, the second fixing portion 330 may be connected to the first fixing portion 110 by plugging, screwing, snapping, or other appropriate fixing methods. The first fixing portion 110 may be a protrusion, groove, threaded hole, or other form of fixing structure on the housing 100. The second fixing portion 330 may be a structure that matches the corresponding first fixing portion 110, for example, a groove that matches the protrusion, a protrusion that matches the groove line, or a threaded column that matches the threaded hole, so that each electrode 300 can form a stable connection with the corresponding first fixing portion 110 through its second fixing portion 330, thereby being fixed to the housing 100. In this way, the second fixing portion 330 of each electrode 300 can cooperate with the corresponding first fixing portion 110 of the shell 100, so that each electrode 300 can be accurately fixed at a predetermined position, thereby helping to reduce the risk of displacement or falling off of the electrode 300 during use, and further helping to improve the structural stability of the entire electrode head 20.

[0046] In some embodiments, the housing 100 may further include a plurality of first positioning portions 120, each of which may correspond to a plurality of electrodes 300. Each electrode 300 may include a second positioning portion 340, and the second positioning portion 340 of each electrode 300 may be positioned and matched with the corresponding first positioning portion 120. Specifically, the first fixing portion 110 may be a protrusion, a groove, a positioning hole, or other positioning structure of the housing 100, and the second positioning portion 340 may be designed as a structure that matches the corresponding first positioning portion 120, for example, a groove that matches a protrusion, a protrusion that matches a groove, or a positioning column that matches a positioning hole, so that each electrode 300 can be accurately positioned with the corresponding first positioning portion 120 through its own second positioning portion 340. In this way, the second positioning portion 340 of each electrode 300 can match the corresponding first positioning portion 120 of the housing 100, so that each electrode 300 can be accurately positioned at a predetermined position, thereby helping the operator to quickly and conveniently install the electrode 300 on the housing 100.

[0047] In some embodiments, the first fixing portion 110 is a fixing hole, the first positioning portion 120 is a positioning hole, the second fixing portion 330 is a fixing post, and the second positioning portion 340 is a positioning post. Each second fixing portion 330 is plugged into and matched with the corresponding first fixing portion 110, and each second positioning portion 340 is plugged into and matched with the corresponding first positioning portion 120. In this way, through the design of the plug-fitting fixing posts and fixing holes, and the positioning posts and positioning holes, a compact and stable connection between the electrode 300 and the housing 100 is achieved, thereby facilitating the loosening or falling off of the electrode 300 during use, improving the structural stability and reliability of the entire electrode head 20, and having a simple structure and relatively convenient operation.

[0048] In some embodiments, the second positioning portion 340 is a blind hole, which not only helps to position the electrode 300, but also helps to reduce the risk of the shell 100 itself being reduced in strength due to the opening of multiple through holes, and reduces the risk of essence entering the shell 100 through the second positioning portion 340.

[0049] In this embodiment, the first fixing part 110 can be provided with a threaded column with an internal thread, and the second fixing part 330 can be a threaded hole with an internal thread. The first fixing part 110 can be fixed to the corresponding second fixing part 330 by screws. The precise plug-in fit of the positioning column and the positioning hole can improve the pre-positioning of the first fixing part 110 and the corresponding second fixing part 330, so that the electrode 300 can be accurately positioned on the shell 100, which helps to reduce the risk of position deviation or rotation of the electrode 300 during installation.

[0050] See also Figures 2 to 7In some embodiments, the light-transmitting member 200 may be provided with a plurality of avoidance notches 220. Each of the connection points between the electrode 300 and the housing 100 may be provided with an avoidance notch 220. The avoidance notches 220 are used to allow the light-transmitting member 200 to avoid the second fixing portion 330 and the second positioning portion 340. Thus, when the electrode 300 is plugged into and mated with the first fixing portion 110 of the housing 100 via the second fixing portion 330, the avoidance notches 220 provide sufficient space for the connection between the second fixing portion 330 and the first fixing portion 110, ensuring that the connection between the second fixing portion 330 and the first fixing portion 110 is not interfered with by the light-transmitting member 200. Furthermore, when the electrode 300 is positioned and mated with the first positioning portion 120 of the housing 100 via the second positioning portion 340, the avoidance notches 220 provide sufficient space for the connection between the second positioning portion 340 and the first positioning portion 120, ensuring that the connection between the second fixing portion 330 and the first fixing portion 110 is not obstructed by the light-transmitting member 200. In addition, since the light-transmitting member 200 is provided with an avoidance notch 220, the light-transmitting member 200 does not need to have a through hole to meet the connection between the electrode 300 and the shell 100, so that the light-emitting surface 210 of the light-transmitting member 200 is relatively complete, thereby helping to avoid the risk of essence entering the shell 100 from the light-transmitting member 200.

[0051] See also Figure 3 In some embodiments, the electrode head 20 may further include a plurality of first sealing rings 410. The first sealing rings 410 may be silicone sealing rings or rubber sealing rings, etc. The plurality of first sealing rings 410 may respectively correspond to the plurality of electrodes 30. The second fixing portion 330 may be passed through the corresponding first sealing rings 410. The first sealing rings 410 may abut against the shell 100 and the corresponding electrode 300, thereby helping to improve the sealing of the electrode head 20 at the connection between the first fixing portion 110 and the second fixing portion 330, thereby helping to reduce the risk of essence entering the shell 100 from the connection between the first fixing portion 110 and the second fixing portion 330.

[0052] In some embodiments, the electrode head 20 may further include a second sealing ring 420, which may be a silicone sealing ring or a rubber sealing ring, etc. The shell 100 may be provided with a light exit hole 130, the light transmissive member 211 may be located at the light exit hole 130, and the second sealing member 420 may be arranged around the edge of the light exit hole 130. The second sealing member 420 may abut against the light transmissive member 200 and the shell 100, thereby helping to improve the sealing of the electrode head 20 at the connection between the light transmissive member 200 and the shell 100, and helping to reduce the risk of essence entering the shell 100 from the connection between the light transmissive member 200 and the shell 100.
