[0002] In the related art, the handheld cosmetic instrument usually comprises a handheld part and an electrode head, the surface of the side of the electrode head away from the handheld part is a nursing surface, and the electrode head can nurse the skin through the nursing surface after being electrified.

DETAILED DESCRIPTION

[0030] Reference is made below Figures 1-9 to describe the beauty instrument 100 according to the embodiments of the present application.

[0031] As Figures 1-9 shown, the beauty instrument 100 according to the embodiments of the present application comprises a main body 10 and a care head 20.

[0032] Specifically, the main body 10 has a first direction (e.g., the up-down direction in the figure), a second direction (e.g., the left-right direction in the figure) and a third direction (e.g., the front-back direction in the figure) orthogonal to each other. The care head 20 is arranged on one side of the main body 10 in the first direction, and the care head 20 comprises a shell 210 and a plurality of electrodes 220. In the description of the present application, the meaning of "a plurality of" is two or more. The plurality of electrodes 220 are all arranged on the shell 210 and are spaced apart along the second direction, and each electrode 220 extends along the third direction. Figure 1 Figure 1 Figure 1

[0033] It should be noted that the first direction can be the height direction of the main body 10, the second direction can be the length direction of the main body 10, and the third direction can be the thickness direction of the main body 10.

[0034] For example, in Figures 1-9 ​​​In the example, the main body 10 has a receiving cavity containing a circuit board and a power supply component. The care head 20 is mounted on one side of the main body 10 in the height direction, and the housing 210 can be connected to the main body 10 by a snap-fit ​​mechanism. Multiple electrodes 220 are evenly spaced along the length direction of the main body 10. Each electrode 220 is approximately crescent-shaped and extends in the third direction. The surface of each electrode 220 away from the main body 10 is flush with the surface of the housing 210 away from the main body 10, making the outer surface (i.e., the care surface) of the care head 20 smoother and facilitating contact between the care surface and the skin.

[0035] Among them, such as Figure 5 As shown, in the projection plane of the second direction, the side surface of the housing 210 away from the main body 10 is a first arc-shaped surface 211. That is, when the nursing head 20 is cut along a plane parallel to the first direction and the third direction, the side surface of the cross-section of the nursing head 20 away from the main body 10 is a first arc-shaped surface 211, and the first arc-shaped surface 211 protrudes outward, that is, the first arc-shaped surface 211 is arched.

[0036] The radius of curvature of the first arc-shaped surface 211 is K1, where K1 satisfies: 13mm ≤ K1 ≤ 116mm. When K1 < 13mm, the radius of curvature of the first arc-shaped surface 211 is small, making it closer to a flat surface. During skincare, the user needs to move a lot to ensure that the first arc-shaped surface 211 makes contact with the skin over a large area, resulting in poor user comfort. When K1 > 116mm, the radius of curvature of the first arc-shaped surface 211 is small, making it too convex. This results in a smaller contact area between the first arc-shaped surface 211 and the skin, affecting the skincare effect of the beauty device 100. Furthermore, to ensure sufficient contact between the first arc-shaped surface 211 and the skin, the user needs to squeeze the skin forcefully to achieve a large contact area, leading to poor user comfort.

[0037] Since the orientation of each electrode 220 is basically consistent with the orientation of the first arc-shaped surface 211, by controlling the radius of curvature K1 of the first arc-shaped surface 211 between 13mm and 116mm, the first arc-shaped surface 211 has a suitable curvature. During skin care, the user can make the first arc-shaped surface 211 contact the skin as much as possible with slight hand movements, which can increase the contact area between the first arc-shaped surface 211 and the skin. At the same time, the user does not need to squeeze the skin forcefully. While ensuring the skin care effect of the beauty device 100, the user's comfort during use can also be guaranteed.

[0038] According to the cosmetic instrument 100, the curvature radius of the side surface (i.e. the first arc surface 211) of the shell 210 away from the main body 10 is controlled to be between 13mm and 116mm in the second direction projection plane, the adhesion of the first arc surface 211 to the face of the user can be increased, the contact area of the first arc surface 211 to the skin is increased, and the comfort of the user during use can be ensured while the skin care effect of the cosmetic instrument 100 is ensured.

[0039] According to some embodiments of the utility model, as Figures 2-4 shown, the first arc surface 211 includes a first arc segment 211a and a second arc segment 211b, and the length of the first arc segment 211a is greater than the length of the second arc segment 211b. Since the first arc segment 211a is located on the front of the cosmetic instrument 100, and the first arc segment 211a is more often in contact with the skin when the user is using the cosmetic instrument 100, by setting the length of the first arc segment 211a to be longer, the area of the first arc segment 211a can be increased, which is beneficial to arranging more electrodes 220 in the first arc segment 211a, so that the electrodes 220 can be fully in contact with the skin, and the cosmetic instrument 100 has a better skin care effect.

[0040] Further, in the projection plane of the second direction, the curvature radius of the first arc segment 211a is K2, and the curvature radius of the second arc segment 211b is K3, wherein K2 and K3 satisfy: 13.18mm≤K2≤116mm, and 13mm≤K3≤65mm.

[0041] As Figures 2-4 shown, since the length of the first arc segment 211a is large, the first arc segment 211a is more often in contact with the skin when a large area of skin is cared for. When K2<13.18mm, the curvature radius of the first arc segment 211a is small, so that the first arc segment 211a is more close to a plane, and the user needs to move greatly when changing the skin care area to ensure that the first arc segment 211a is in contact with the skin in a large area, which results in poor comfort of the user during use; when K2>116mm, the curvature radius of the first arc segment 211a is large, so that the first arc segment 211a is too raised, in order to ensure that the first arc segment 211a is in full contact with the skin, the user needs to press the skin hard to make the first arc segment 211a in contact with the skin in a large area, which also results in poor comfort of the user during use.

[0042] Because the second arc segment 211b is relatively short, it can be used to contact the skin when applying skincare products to small areas. When K3 < 13mm, the radius of curvature of the second arc segment 211b is small, making it closer to a flat surface. Users need to move significantly when changing skincare areas to ensure that the second arc segment 211b can contact the skin, resulting in poor user comfort. When K3 > 65mm, the radius of curvature of the second arc segment 211b is large, making it too convex. To ensure sufficient contact between the second arc segment 211b and the skin, users need to squeeze the skin forcefully, again resulting in poor user comfort.

[0043] Therefore, by controlling the radius of curvature K2 of the first arc segment 211a between 13.18mm and 116mm, and the radius of curvature K3 of the second arc segment 211b between 13mm and 65mm, the orientation of the first arc segment 211a and the second arc segment 211b can fit more closely to the user's face. This not only further ensures the skincare effect of the beauty device 100, but also further improves the user's comfort and user experience.

[0044] Furthermore, within the projection plane in the second direction, the radian of the first arc segment 211a is α, and the radian of the second arc segment 211b is β, wherein α and β satisfy: 60︒≤α≤150︒, 50︒≤β≤160︒ respectively.

[0045] like Figure 2 As shown, due to the small curvature of the first arc segment 211a, when α < 60°, the curvature of the first arc segment 211a is small, causing its direction to approach a plane. Furthermore, the area of ​​the first arc segment 211a is small, requiring significant movement from the user when changing skincare areas, resulting in poor user comfort. When α > 150°, the curvature of the first arc segment 211a is large, increasing its area and thus the size and cost of the beauty device 100. Therefore, by controlling the curvature of the first arc segment 211a between 60° and 150°, user comfort can be ensured while reducing costs, facilitating the miniaturization design of the beauty device 100.

[0046] Since the curvature of the first arc-shaped segment 211a is small, when β < 50°, the curvature of the second arc-shaped segment 211b is small, so that the second arc-shaped segment 211b tends to be a plane, and the area of the second arc-shaped segment 211b is small, so that the user needs to move greatly when changing the skin care area, which leads to poor comfort when the user uses; when β > 160°, the curvature of the second arc-shaped segment 211b is large, which increases the area of the second arc-shaped segment 211b, and increases the size and cost of the beauty instrument 100. Therefore, by controlling the curvature of the second arc-shaped segment 211b to be between 50° and 160°, the comfort of the user when using can be ensured, and the cost can be reduced, which is beneficial to the miniaturization design of the beauty instrument 100.

[0047] According to some embodiments of the present application, as shown in Figure 5 the side surface of the shell 210 away from the main body 10 is a second arc-shaped surface 212 in the projection plane of the third direction, and the radius of curvature of the second arc-shaped surface 212 is K4, wherein the K4 satisfies: 11mm ≤ K4 ≤ 220mm. When K4 < 11mm, the radius of curvature of the second arc-shaped surface 212 is small, so that the second arc-shaped surface 212 tends to be a plane more, and when the second arc-shaped surface 212 slides on the skin, the smoothness between the second arc-shaped surface 212 and the skin is reduced, which leads to poor comfort when the user uses; when K4 > 220mm, the radius of curvature of the second arc-shaped surface 212 is small, so that the second arc-shaped surface 212 is too raised, which leads to a small contact area between the second arc-shaped surface 212 and the skin, affects the skin care effect of the beauty instrument 100, and in order to ensure that the second arc-shaped surface 212 is in full contact with the skin, the user needs to press the skin hard to make the second arc-shaped surface 212 in large-area contact with the skin, which leads to poor comfort when the user uses.

[0048] Therefore, by controlling the radius of curvature K1 of the second arc-shaped surface 212 to be between 11mm and 220mm, the second arc-shaped surface 212 has an appropriate curvature, which ensures the smoothness of the second arc-shaped surface 212 when sliding on the skin, and the user does not need to press the skin hard to increase the contact area between the second arc-shaped surface 212 and the skin, so that the beauty instrument 100 has a good skin care effect, and the comfort of the user when using is ensured.

[0049] According to some specific embodiments of the present application, the second arc-shaped surface 212 includes a third arc-shaped segment 212a and two fourth arc-shaped segments 212b, and the two fourth arc-shaped segments 212b are respectively arranged on both sides of the third arc-shaped segment 212a in the second direction. Referring to Figure 5 , the two fourth arc-shaped segments 212b are symmetrically arranged about the center of the third arc-shaped segment 212a.

[0050] Specifically, in the projection plane of the third direction, the third arc-shaped segment 212a has a radius of curvature K5, and each fourth arc-shaped segment 212b has a radius of curvature K6, where K5 and K6 satisfy 24mm≤K5≤220mm and 11mm≤K6≤93mm, respectively.

[0051] When K5<24mm, the radius of curvature of the third arc-shaped segment 212a is small, so that the third arc-shaped segment 212a is more close to a plane, which reduces the smoothness of the third arc-shaped segment 212a when sliding on the skin, resulting in poor comfort of the user when using; when K5>220mm, the radius of curvature of the third arc-shaped segment 212a is small, so that the third arc-shaped segment 212a is too raised, resulting in a small contact area between the third arc-shaped segment 212a and the skin, affecting the skin care effect of the beauty instrument 100, and in order to ensure that the third arc-shaped segment 212a is in full contact with the skin, the user needs to press the skin hard to make the third arc-shaped segment 212a in large-area contact with the skin, resulting in poor comfort of the user when using. Therefore, by controlling the radius of curvature K5 of the third arc-shaped segment 212a to be between 24mm and 220mm, the comfort of the user when using can be further increased.

[0052] When K6<11mm, the radius of curvature of the fourth arc-shaped segment 212b is small, so that in order to make the connection between the fourth arc-shaped segment 212b and the third arc-shaped segment 212a smooth and transition, the length of the third arc-shaped segment 212a needs to be set large, which increases the size and cost of the beauty instrument 100 in the second direction; when K6>93mm, the radius of curvature of the fourth arc-shaped segment 212b is small, so that the third arc-shaped segment 212a is too raised, resulting in a reduced distance between the two third arc-shaped segments 212a, which affects the connection reliability of the shell 210 and the main body 10. Therefore, by controlling the radius of curvature K6 of the fourth arc-shaped segment 212b to be between 11mm and 93mm, the cost can be reduced, the size of the beauty instrument 100 in the second direction can be shortened, and the connection reliability of the shell 210 and the main body 10 can be ensured.

[0053] According to some embodiments of the present application, with reference to Figure 5 In the projection plane of the third direction, the third arc-shaped segment 212a has an arc angle γ, and each fourth arc-shaped segment 212b has an arc angle λ, where γ and λ satisfy 80°≤γ≤160° and 31°≤λ≤90°, respectively.

[0054] Since the plurality of electrodes 220 are arranged in the third arc segment 212a, and in order to prevent the current from being too concentrated after the electrodes 220 are powered on, the plurality of electrodes 220 are usually arranged uniformly in the third arc segment 212a according to a certain rule. When γ < 80°, the length of the third arc segment 212a is relatively short, and the number of electrodes 220 on the third arc segment 212a will be reduced, thereby affecting the skin care effect of the beauty instrument 100; when γ > 160°, the length of the third arc segment 212a is relatively long, and the number of electrodes 220 on the third arc segment 212a will be increased, thereby increasing the cost of the beauty instrument 100. Therefore, by controlling the radian γ of the third arc segment 212a to be between 80° and 160°, both the cost and the skin care effect can be ensured.

[0055] When λ < 31°, the length of the fourth arc segment 212b is relatively short, which will affect the supporting effect of the fourth arc segment 212b on the third arc segment 212a; when λ > 90°, the length of the fourth arc segment 212b is relatively long, which increases the size and cost of the beauty instrument 100 in the first direction. Therefore, by controlling the radian λ of the fourth arc segment 212b to be between 31° and 90°, both the stability of the care head 20 and the cost can be ensured.

[0056] According to some specific embodiments of the present application, the shell 210 further comprises: an outer shell 214 and an inner shell 213, and the inner shell 213 is arranged on the side of the outer shell 214 adjacent to the main body 10 in the first direction. As shown in Figure 1 and Figure 2 The plurality of electrodes 220 are arranged on the outer shell 214 and electrically connected with the circuit board, and the side surface of each electrode 220 away from the main body 10 is flush with the outer surface of the outer shell 214, so as to ensure the flatness of the outer surface of the care head 20. In addition, the shell 210 is arranged in a double-layer structure, which can increase the structural strength of the shell 210, and at the same time, the inner shell 213 can effectively separate the electrodes 220 and the inside of the main body 10, thereby effectively reducing the flow of the outside through the gap between the electrodes 220 and the outer shell 214 into the main body 10, and prolonging the service life of the beauty instrument 100.

[0057] As shown in Figures 2-4 In the projection plane in the second direction, the curvature of the inner shell 213 is greater than that of the outer shell 214. In this way, in the first direction, the side surface of the inner shell 213 away from the main body 10 can be spaced apart from the side surface of the outer shell 214 adjacent to the main body 10, which is beneficial to arranging other functional components in the above gap, so as to make the beauty instrument 100 have more functions and improve the applicability of the beauty instrument 100.

[0058] Further, in the projection plane of the second direction, the curvature radius of the inner shell 213 is K7, wherein K7 satisfies: 2mm≤K7≤200mm. Since the two ends of the outer shell 214 are connected with the two ends of the inner shell 213 in the third direction. When K7<2mm, the curvature radius of the inner shell 213 is small, the trend of the inner shell 213 is relatively gentle, so that the width of the inner shell 213 in the third direction is small, which reduces the structural strength of the shell 210; when K7>200mm, the curvature radius of the inner shell 213 is large, the inner shell 213 is too raised, resulting in that the gap between the inner shell 213 and the outer shell 214 is small, which affects the arrangement of other components. Therefore, by controlling the curvature radius of the inner shell 213 to be between 2mm and 200mm, the shell 210 has good structural strength and is beneficial to the arrangement of other components.

[0059] According to some specific embodiments of the present application, each electrode 220 comprises an electrode body 221 and at least one conductive column 222, the conductive column 222 is arranged on the side of the electrode body 221 adjacent to the shell 210, and the conductive column 222 penetrates the shell 210 and is connected with the circuit board of the main body 10. A plurality of through holes 215 are formed on the shell 210, the plurality of through holes 215 correspond one-to-one to the plurality of electrodes 220, a groove 2211 is formed on one of the inner side wall of the through hole 215 and the outer peripheral wall of the electrode body 221, and a protrusion 216 is arranged on the other one of the inner side wall of the through hole 215 and the outer peripheral wall of the electrode body 221, the protrusion 216 is fitted in the groove 2211.

[0060] For example, in the example of Figure 6 , the electrode body 221 is in a sheet structure, one side of the thickness direction (for example, the up-down direction in Figure 1 ) of the electrode body 221 is provided with two conductive columns 222, each conductive column 222 extends in the direction towards the main body 10, the outer peripheral wall of the electrode body 221 is formed with a groove 2211, and the groove 2211 extends along the circumference of the electrode body 221. The shell 210 is formed with a through hole 215 matched with the shape of the electrode body 221, the inner side wall of the through hole 215 is provided with a protrusion 216, and the protrusion 216 extends along the circumference of the through hole 215. During installation, the protrusion 216 is fitted in the groove 2211 to fix the electrode 220 on the shell 210, and the conductive column 222 is electrically connected with the circuit board, which is beneficial to electrifying the electrode 220, ensures the normal work of the electrode 220, and improves the connection reliability of the electrode 220 and the shell 210.

[0061] According to some embodiments of the present application, the shell 210 is a transparent shell, the main body 10 is provided with a light therapy assembly, the light therapy assembly is connected with the circuit board of the main body 10, and the light emitted by the light therapy assembly is emitted through the transparent shell. Among them, the light therapy assembly can emit light of different colors, through the cooperation of light and electrode 220, the beauty instrument 100 can realize the functions of oil control, inflammation reduction, collagen regeneration promotion, redness reduction, sensitive skin soothing, skin redness or erythema improvement, redness and swelling relief, anti-wrinkle and anti-aging, spot fading, skin color brightening and the like.
