[0024] The embodiments of this utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figures 1-2 The description pertains to a comb head 100 of a nursing comb according to a first aspect embodiment of the present invention.

[0025] like Figure 1 As shown, the comb head 100 of the nursing comb according to a first aspect embodiment of the present invention includes a housing 10, an electrode assembly 20, and a plurality of elastic light guides 30. In the description of the present invention, "a plurality of" means two or more.

[0026] Specifically, the housing 10 has a receiving cavity 11, within which a light-emitting element 40 and a circuit assembly 50 are disposed, and the light-emitting element 40 is electrically connected to the circuit assembly 50. The electrode assembly 20 includes a plurality of electrode elements 21, which are arranged along the length direction of the housing 10 (e.g., Figure 1The electrodes 21 are spaced apart in the left-right direction (as shown in the image). One end of each electrode 21 passes through the housing 10 and is electrically connected to the circuit assembly 50, while the other end of each electrode 21 is adapted to contact the user's head. Each electrode 21 has an elastic light guide 30 on at least one side of the length direction of the housing 10, and one end of each elastic light guide 30 passes through the housing 10 and faces the light-emitting element 40. Each electrode 21 is spaced apart along the thickness direction of the housing 10 (e.g., in the left-right direction). Figure 1 The electrode 21 is movable in the vertical direction and compresses the elastic light guide 30 when it moves toward the housing 10.

[0027] For example, in Figure 1 In the example, the housing 10 is generally a cuboid structure, comprising an upper housing 12 and a lower housing 13, which together define a receiving cavity 11. Electrode components 21 and elastic light guide components 30 are disposed on the upper housing 12. The number of electrode components 21 can be 8, and the number of elastic light guide components 30 can be 16. Each electrode component 21 has an elastic light guide component 30 on both sides of the length direction of the housing 10. The circuit assembly 50 has a rectangular structure, and the light-emitting components 40 are disposed on the side of the circuit assembly 50 near the elastic light guide components 30. The number of light-emitting components 40 can be 16.

[0028] When a user uses the scalp care comb 200 for scalp care, the electrode 21, located away from the housing 10 in the thickness direction, directly contacts the scalp. The light source emitted by the light-emitting element 40 first illuminates the opposing elastic light guide 30, which then diffuses and conducts the light to the scalp. Because the elastic light guide 30 is located on both sides of the electrode 21, compared to the existing structure of the scalp care comb 200 where the electrode head and light-emitting accessories are independently set, the light transmission path is shorter, reducing interference from hair on the light path and allowing the light to be directly directed to the scalp, thus improving the light-emitting efficacy of the scalp care comb 200. Furthermore, each electrode 21 has elastic light guides 30 on both sides of the housing 10 in the length direction, expanding the illumination range and allowing the light to more comprehensively cover the scalp area, further enhancing the light-emitting efficacy of the scalp care comb 200.

[0029] Meanwhile, the electrode 21 is movable along the thickness direction of the housing 10. When the electrode head contacts the scalp, the elastic light guide 30 deforms under pressure. The light emission angle and position of the light guide change with the movement of the electrode head, ensuring that the light is always close to the scalp surface and avoiding light path deviation caused by hair obstruction, further enhancing the light illumination effect of the care comb 200. Moreover, the elastic light guide 30 not only performs the light guiding function but also provides elastic support for the electrode head. When the electrode 21 moves along the thickness direction of the housing 10, the elastic light guide 30 can absorb some of the pressure of the electrode 21 contacting the scalp, ensuring that the electrode 21 is always in flexible contact with the scalp. This avoids the stinging sensation caused by the hard metal electrode head directly contacting the scalp. Furthermore, the deformation of the elastic light guide 30 ensures that the electrode 21 always fits the scalp, providing moderate massage pressure and improving the user experience.

[0030] According to the embodiment of the present invention, the comb head 100 of the nursing comb improves the light illumination effect of the nursing comb 200 and enhances the user experience by providing an elastic light guide 30 on at least one side of the electrode 21 and making the elastic light guide 30 pass through the housing 10 and face the light-emitting element 40.

[0031] It should be noted that the elastic light guide 30 can be made of transparent silicone, the electrode head can be made of stainless steel, and the light-emitting element 40 can be an LED (Light Emitting Diode) lamp bead. This application does not impose specific restrictions on this.

[0032] According to some embodiments of the present invention, each electrode 21 has a groove (not shown in the figure), and an elastic light guide 30 is disposed in the groove; in the length direction of the housing 10, the side surface of the elastic light guide 30 away from the electrode 21 protrudes from the side surface of the electrode 21 adjacent to the elastic light guide 30.

[0033] For example, in Figure 1 In the example, each electrode 21 has grooves on both sides of the housing 10 along its length. The shape of the grooves is the same as the shape of the surface of the elastic light guide 30 adjacent to the electrode 21. The grooves on the electrode 21 provide a limiting function for the elastic light guide 30. After the elastic light guide 30 is embedded in the groove, the sidewall of the groove can limit the displacement or detachment of the elastic light guide 30, ensuring the stability of the position of the elastic light guide 30 and guaranteeing the working reliability of the elastic light guide 30. Moreover, the grooves provide a positioning function for the elastic light guide 30, allowing operators to quickly install the elastic light guide 30 according to the position of the groove, thus improving the installation efficiency of the care comb 200.

[0034] Furthermore, since the side surface of the elastic light guide 30 away from the electrode 21 is the light-emitting surface when the elastic light guide 30 conducts light, and the light is diffused from the side surface of the elastic light guide 30 away from the electrode 21 to the user's scalp, by making the side surface of the elastic light guide 30 away from the electrode 21 protrude from the side surface of the elastic light guide 30 adjacent to the electrode 21, the electrode 21 is prevented from affecting the light guiding effect of the elastic light guide 30. Moreover, the protruding side surface of the elastic light guide 30 away from the electrode 21 makes the light-emitting surface of the elastic light guide 30 closer to the scalp, avoiding the influence of hair blocking the light, and improving the efficacy and light guiding efficiency of the care comb 200.

[0035] It should be noted that the elastic light guide 30 can be fixed in the groove using an encapsulation process, and this application does not impose specific restrictions on this.

[0036] Furthermore, along the length of the housing 10, the surface of the elastic light guide 30 away from the electrode 21 is curved. This configuration allows the elastic light guide 30 to function as a lens, scattering light in multiple directions after refraction through the curved surface, enabling the light source to illuminate a larger area of ​​the scalp and further improving the effectiveness of the care comb 200.

[0037] According to some embodiments of the present invention, in the thickness direction of the housing 10, the minimum distance between the other end of each electrode 21 and the other end of each elastic light guide 30 is h, wherein h satisfies: 3.0mm≤h≤5.0mm.

[0038] When h < 3.0 mm, the minimum distance between the other end of each electrode 21 and the other end of each elastic light guide 30 in the thickness direction of the housing 10 is too small, that is, the area covered by the elastic light guide 30 on the electrode 21 is too large, which may affect the care effect of the electrode 21 on the scalp, and will increase the weight and material cost of the elastic light guide 30.

[0039] When h > 5.0 mm, the minimum distance between the other end of each electrode 21 and the other end of each elastic light guide 30 is too large in the thickness direction of the housing 10. That is, the distance between the elastic light guide 30 and the scalp is too large. After the light is emitted from the light-emitting surface of the elastic light guide 30, it is easily blocked by the hair and may not be able to reach the scalp, thus affecting the light illumination effect of the care comb 200.

[0040] Therefore, by setting the minimum distance h between the other end of each electrode 21 and the other end of each elastic light guide 30 in the thickness direction of the housing 10 to 3.0mm~5.0mm, the care effect of the electrode 21 on the scalp is guaranteed, the weight and material cost of the elastic light guide 30 are reduced, and the light blocking effect of hair is avoided, so that the light can reach the scalp area directly and the light illumination effect of the care comb 200 is improved.

[0041] According to some embodiments of the present invention, in the width direction of the housing 10, the minimum distance between the edge of each electrode 21 and each elastic light guide 30 is L, wherein L satisfies: 2.0mm≤L≤3.0mm.

[0042] When L < 2.0 mm, the minimum distance between the edge of each electrode 21 and each elastic light guide 30 in the width direction of the housing 10 is too small, that is, the area covered by the elastic light guide 30 on the electrode 21 is too large, which may affect the care effect of the electrode 21 on the scalp, and will increase the weight and material cost of the elastic light guide 30.

[0043] When L > 3.0 mm, the minimum distance between the edge of each electrode 21 and each elastic light guide 30 is too large in the width direction of the housing 10. That is, the area covered by the elastic light guide 30 on the electrode 21 is too small, and the distance between the elastic light guide 30 and the scalp is increased, which reduces the range of light illumination and makes it impossible for the light to cover the scalp area more comprehensively, thus affecting the light illumination effect of the care comb 200.

[0044] Therefore, by setting the minimum distance L between the edge of each electrode 21 and each elastic light guide 30 in the width direction of the housing 10 to 2.0mm~3.0mm, the care effect of the electrode 21 on the scalp is guaranteed, the weight and material cost of the elastic light guide 30 are reduced, and the range of light illumination is expanded so that the light covers the scalp area more comprehensively, thereby improving the light illumination effect of the care comb 200.

[0045] In some embodiments, the width of each electrode 21 gradually increases in the width direction of the housing 10 along the direction toward the housing 10; and / or the width of each elastic light guide 30 gradually increases in the width direction of the housing 10 along the direction toward the housing 10.

[0046] For example, in Figure 1In the example, along the direction toward the housing 10, the width of each electrode 21 in the width direction of the housing 10 gradually increases, and the width of each elastic light guide 30 in the width direction of the housing 10 gradually increases; or, only along the direction toward the housing 10, the width of each electrode 21 in the width direction of the housing 10 gradually increases (not shown); or, only along the direction toward the housing 10, the width of each elastic light guide 30 in the width direction of the housing 10 gradually increases (not shown).

[0047] Along the direction towards the housing 10, the width of each electrode 21 gradually increases in the width direction of the housing 10. That is, the width of the part where the electrode 21 connects to the housing 10 is larger. When the electrode 21 is inserted into the housing 10, the increased width makes it secure, reducing the risk of the electrode 21 loosening or falling out of the housing 10 and improving the working reliability of the care comb 200. Moreover, along the direction away from the housing 10, the width of each electrode 21 gradually decreases in the width direction of the housing 10. That is, the free end of the electrode 21 is narrower. During the user's combing process, the free end of the electrode 21 can more easily pass through the hair strands, and the gradually widening structure can part the hair, allowing light to shine on the scalp and avoiding the hair's blocking effect on the light. This allows the light to reach the scalp area directly, improving the light illumination effect of the care comb 200.

[0048] Furthermore, along the direction towards the housing 10, the width of each elastic light guide 30 gradually increases in the width direction of the housing 10. This means the portion connecting the elastic light guide 30 to the housing 10 is wider. When the elastic light guide 30 is inserted into the housing 10, the increased width causes it to lock in place, reducing the risk of it loosening or falling out. Moreover, since the elastic light guide 30 can provide some support for the electrode 21, increasing the width of the portion connecting the elastic light guide 30 to the housing 10 allows for stable support of the electrode 21, improving the operational reliability of the care comb 200. Additionally, the portion connecting the elastic light guide 30 to the housing 10 is closer to the light-emitting element 40. Increasing the width of this portion allows for the reception of more light from the light-emitting element 40, reducing light loss. Simultaneously, the gradually widening structure allows light to be emitted more evenly when reflected by the elastic light guide 30, further enhancing the illumination efficiency of the care comb 200.

[0049] According to some embodiments of the present invention, each elastic light guide 30 includes a first elastic segment 31 and a second elastic segment 32. The first elastic segment 31 is disposed on one side of the electrode 21 along the length direction of the housing 10, and extends along the thickness direction of the housing 10. The second elastic segment 32 is connected to the first elastic segment 31 and located within the receiving cavity 11, extending along the length direction of the housing 10 and opposite to the light-emitting element 40.

[0050] like Figure 1 As shown, the first elastic segment 31 is connected to the electrode 21, and the second elastic segment 32 is connected to the inner wall of the housing 10. The second elastic segment 32, connected to the housing 10, provides support for the first elastic segment 31 and the electrode 21, preventing the elastic light guide 30 and the electrode 21 from loosening or falling out of the housing 10, thus ensuring the reliability of the care comb 200. Simultaneously, when the electrode 21 moves along the thickness direction of the housing 10, the first elastic segment 31 moves with it, causing the portion of the second elastic segment 32 connected to the first elastic segment 31 to undergo elastic deformation. This provides a certain amount of movement space for the electrode head, ensuring that the electrode 21 remains in flexible contact with the scalp, improving the user experience. Furthermore, since both the first elastic segment 31 and the second elastic segment 32 are transparent light guide structures, when the electrode 21 moves along the thickness direction of the housing 10, both the first elastic segment 31 and the second elastic segment 32 can act as light guides, receiving more light from the light-emitting element 40, reducing light loss, and improving the illumination efficiency of the care comb 200.

[0051] According to some embodiments of this utility model, the hardness of the elastic light guide 30 is H, wherein H satisfies: 60≤H≤80.

[0052] When H < 60, the hardness of the elastic light guide 30 is too low, that is, the elastic light guide 30 is too soft. When the light guide is deformed under force, its internal light path will bend due to the change in shape. The light may not be able to be transmitted along the preset path, causing the irradiation area to deviate from the target position (such as irradiating the hair roots instead of the scalp surface). Moreover, the elastic light guide 30 is too soft and may be difficult to lock in the groove. It is easy to shake and detach from the electrode head during use, affecting the structural stability of the care comb 200. In addition, the second elastic segment 32 is too soft and may not provide enough support for the first elastic segment 31 and the electrode 21, causing the elastic light guide 30 and the electrode 21 to loosen or fall off from the housing 10, making it difficult to ensure the working reliability of the care comb 200.

[0053] When H > 80, the elastic light guide 30 is too hard, that is, the elastic light guide 30 is too rigid. The elastic light guide 30 cannot deform with the contact pressure of the electrode 21, so the electrode 21 cannot always be in flexible contact with the scalp. This results in the electrode head rigidly contacting the scalp and causing a stinging sensation, resulting in a poor user experience.

[0054] Therefore, by setting the hardness H of the elastic light guide 30 between 60 and 80, the light illumination efficiency and working reliability of the care comb 200 are improved, as well as the user experience.

[0055] In some alternative embodiments, the comb head 100 of the care comb also includes a pressure plate 60 and a waterproof component 70. The pressure plate 60 is disposed within the receiving cavity 11, and the pressure plate 60 and the circuit assembly 50 are arranged along the thickness direction of the housing 10. The waterproof component 70 is disposed within the receiving cavity 11, located on the side of the pressure plate 60 away from the circuit assembly 50, and the waterproof component 70 is integrally formed with the elastic light guide 30.

[0056] like Figure 1 As shown, the pressure plate 60 has an irregular sheet-like structure. The electrode head passes through the pressure plate 60 and connects to the circuit assembly 50 at one end of the thickness direction of the housing 10 near the circuit assembly 50. The pressure plate 60 is provided with a square clearance hole 61 to avoid blocking the light-emitting element 40. The waterproof element 70 is located on the outer periphery of the second elastic segment 32 of the elastic light guide 30. Along the thickness direction of the housing 10, one side of the waterproof element 70 is connected to the inner wall of the housing 10, and the other side is connected to the pressure plate 60. The waterproof element 70 is located near the connection between the upper housing 12 and the lower housing 13.

[0057] This configuration allows the pressure plate 60 to press the waterproof component 70 tightly against its periphery, preventing movement of the waterproof component 70 and the elastic light guide 30 within the housing 10. This ensures the operational reliability of the elastic light guide 30. Simultaneously, the pressure plate 60 restricts the freedom of the elastic light guide 30 in the thickness direction of the housing 10, and the presence of a certain distance between the pressure plate 60 and the elastic light guide 30 allows for some elastic expansion and contraction. Furthermore, the waterproof component 70 prevents external dust and moisture from entering the receiving cavity 11 through the connection between the upper housing 12 and the lower housing 13, thus protecting the circuit assembly 50 and the light-emitting component 40 and ensuring the overall operational reliability and service life of the care comb 200. Moreover, the waterproof component 70 and the elastic light guide 30 are integrally molded, preventing breakage at the connection between the waterproof component 70 and the elastic light guide 30 due to individual stress on the elastic light guide 30, thus ensuring the overall structural stability of the waterproof component 70 and the elastic light guide 30.

[0058] It should be noted that the waterproof component 70 can be made of silicone material, and this application does not impose specific restrictions on this.

[0059] Specifically, the comb head 100 of the nursing comb also includes a plurality of elastic connectors (not shown in the figure), each elastic connector being sleeved on the corresponding electrode 21. The elastic connectors are located between the circuit assembly 50 and the pressure plate 60, and one end of the elastic connector in the thickness direction of the housing 10 is connected to the circuit assembly 50.

[0060] The elastic connector provides axial restraint to the electrode 21, ensuring that it moves only in the thickness direction of the housing 10, preventing lateral wobbling upon contact with the scalp and thus improving the user experience. Simultaneously, as the electrode head moves, the elastic connector deforms due to the contact pressure on the electrode 21. This, combined with the elastic light guide 30, prevents the electrode 21 from maintaining constant, flexible contact with the scalp, further enhancing the user experience. Furthermore, the elastic connector provides support to the electrode head, preventing it from loosening or detaching from the housing 10, ensuring the reliability of the care comb 200.

[0061] It should be noted that the elastic connector can be a spring, and this application does not impose any specific restrictions on it.

[0062] like Figure 2 As shown, the nursing comb 200 according to the second aspect embodiment of the present invention includes the comb head 100 of the nursing comb according to the first aspect embodiment of the present invention.

[0063] According to the embodiment of the present utility model, the nursing comb 200 improves the light-illuminating effect of the nursing comb 200 by adopting the above-mentioned comb head 100, enhances the user experience, and ensures the working reliability of the nursing comb 200.

[0064] Other configurations and operations of the nursing comb 200 according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
