[0033] The embodiments of this utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figures 1-6 The comb tooth 100 according to an embodiment of the present utility model is described. The comb tooth 100 includes: a housing 10 and at least one first care structure 20.

[0034] Specifically, such as Figure 1 and Figure 2 As shown, the housing 10 has a mounting surface 11. The housing 10 has a first direction A and a second direction B. The length of the mounting surface 11 in the first direction A is greater than the length in the second direction B. A first care structure 20 is disposed on the housing 10. At least a portion of the first care structure 20 protrudes from the mounting surface 11. The first care structure 20 includes a care section 21 with a spray nozzle. The care section 21 extends along the second direction B. The projection of the care section 21 onto the mounting surface 11 in a direction perpendicular to the mounting surface 11 gradually decreases in size from the middle region to both ends along the second direction B. The first direction A and the second direction B are perpendicular to each other.

[0035] The housing 10 includes a cover plate 12 and a main housing 13, the cover plate 12 and the main housing 13 forming a detachable fit, the cover plate 12 along... Figure 1 The third direction C, i.e. the thickness direction of the comb teeth 100, is the side surface away from the main housing 13, which is the mounting surface 11. The first care structure 20 is provided on the cover plate 12, and at least a part of the first care structure 20 protrudes from the mounting surface 11 along the third direction C in a direction away from the main housing 13. The part of the first care structure 20 that protrudes from the mounting surface 11 is the care part 21. The spray nozzle penetrates the central area of ​​the side surface of the care part 21 away from the mounting surface 11 along the third direction C. The care liquid inside the comb teeth 100 is suitable for spraying onto the user's head through the spray nozzle. The projected area of ​​the care part 21 along the third direction C on the mounting surface 11 gradually decreases from the middle area of ​​the care part 21 towards both ends along the second direction B.

[0036] According to the present invention, the comb teeth 100, through the design that the projection of the care part 21 on the mounting surface 11 gradually decreases towards both ends along the second direction B, optimizes the first care structure 20, so that the two ends of the care part 21 along the second direction B form sharp points. Thus, when the user uses the comb teeth 100, the two ends of the care part 21 can separate the user's hair and expose the scalp along the second direction B, and the spray nozzle can directly spray the care liquid onto the user's scalp, thereby maximizing the care effect of the comb teeth 100 on the user's scalp and achieving hair care and health, improving the reliability of the comb teeth 100, avoiding excessive obstruction of the care liquid by the hair, and maximizing the effectiveness of the comb teeth 100.

[0037] In this application, the first nursing structure 20 and the cover plate 12 are integrally molded, which can improve the structural strength of the first nursing structure 20 and the cover plate 12, improve the production efficiency of the comb teeth 100, and reduce the production cost.

[0038] According to some embodiments of this utility model, such as Figure 2 As shown, the first nursing structure 20 has a nursing surface 23. The nursing part 21 is constructed as the nursing surface 23 on the side away from the housing 10 along the direction of the vertical mounting surface 11. The nursing surface 23 is recessed in the direction of the vertical mounting surface 11, i.e., the third direction C towards the housing 10.

[0039] The surface of the care section 21 away from the mounting surface 11 of the housing 10 along the third direction C is the care surface 23. The care surface 23 is recessed along the third direction C towards the mounting surface 11 of the housing 10. In this application, a light-transmitting opening 26 is formed on the care surface 23, and care light can be irradiated onto the user's scalp from inside the housing 10 through the light-transmitting opening 26. Thus, by designing the care surface 23 to be recessed along the third direction C towards the mounting surface 11 of the housing 10, the structure of the care section 21 is optimized, which can improve the focusing effect of the care surface 23 on the care light, improve the care effect of the comb teeth 100, and at the same time, facilitate the better formation of the tips at both ends of the care section 21 along the second direction B, ensuring that the two ends of the care section 21 can smoothly separate the user's hair. It can also increase the distance between the spray nozzle and the user's scalp, avoiding the spray nozzle being too close to the user's scalp and causing the care liquid to not be able to spray out, ensuring that the spray nozzle can smoothly spray the care liquid, and improving the reliability of the care provided by the comb teeth 100.

[0040] According to some embodiments of this utility model, such as Figure 5 As shown, the nursing surface 23 is constructed as an arc surface, and the radius of curvature of the nursing surface 23 is R, which satisfies: 15.5mm≤R≤30.5mm.

[0041] When the radius of curvature of the nursing surface 23 is less than 15.5 mm, the radius of curvature of the nursing surface 23 is too small, and the degree of curvature of the nursing surface 23 is too large, which may result in low structural strength of the nursing part 21. When the radius of curvature of the nursing surface 23 is greater than 30.5 mm, the radius of curvature of the nursing surface 23 is too large, and the degree of curvature of the nursing surface 23 is too small, which makes it difficult for the two ends of the nursing part 21 to form sharp points and makes it difficult for the spray nozzle to spray the nursing liquid smoothly. For example, R=20 mm.

[0042] Therefore, by limiting the range of the radius of curvature of the care surface 23, while ensuring the structural strength of the care section 21, it is easy for the care surface 23 to form a smoother arc effect, improve the ability of the care surface 23 to focus the care light, facilitate the formation of sharp points at both ends of the care section 21, and ensure that the spray nozzle can smoothly spray the care liquid, thereby improving the care effect of the comb teeth 100.

[0043] According to some embodiments of this utility model, such as Figure 3 As shown, the projection of the nursing surface 23 onto the mounting surface 11 in the direction perpendicular to the mounting surface 11, i.e., the third direction C, includes a first contour line 24 and a second contour line 25. The first contour line 24 and the second contour line 25 are at least partially spaced apart along the first direction A. The first contour line 24 or the second contour line 25 is a curve, and the two ends of the first contour line 24 and the second contour line 25 extend towards each other at their respective inclinations along the second direction B.

[0044] In this application, both the first contour line 24 and the second contour line 25 are curved. The first contour line 24 and the second contour line 25, which are adjacent to the central area of ​​the nursing section 21, are spaced apart along the first direction A. The first contour line 24 and the second contour line 25, which are away from the central area of ​​the nursing section 21, extend obliquely along the first direction A toward each other and connect with each other. Thus, by designing the first contour line 24 and the second contour line 25 as curved, it is convenient for the two ends of the nursing section 21 to form sharp points along the second direction B, so that the two ends of the nursing section 21 can better separate the user's hair.

[0045] Optionally, the first contour line 24 and the second contour line 25 are symmetrically arranged along the central axis of the second direction B of the nursing section 21.

[0046] According to some embodiments of this utility model, such as Figure 4 As shown, the first contour line 24 and the second contour line 25 are connected to each other at both ends along the second direction B to form an included angle α, where α satisfies: 0 < α < 90°.

[0047] When the angle formed by connecting the two ends of the first contour line 24 and the second contour line 25 along the second direction B is greater than 90°, the angle between the two ends of the first contour line 24 and the second contour line 25 along the second direction B is too large, which may cause the two ends of the care section 21 to be unable to separate the user's hair well, or the effect of separating the user's hair may not be significant. For example, α=30°.

[0048] Therefore, by limiting the range of the included angle formed by connecting the two ends of the first contour line 24 and the second contour line 25 along the second direction B, and limiting the included angle to an acute angle, the two ends of the care section 21 can more significantly separate the user's hair, thereby ensuring that the spray nozzle on the care section 21 directly sprays the care solution onto the user's scalp, improving the care effect and reliability of the comb 100.

[0049] According to some embodiments of this utility model, such as Figure 3As shown, the projection of the nursing part 21 on the mounting surface 11 along the direction perpendicular to the mounting surface 11 has a length of L1 along the second direction B, and the projection of the nursing part 21 on the mounting surface 11 along the direction perpendicular to the mounting surface 11 has a length of L2 along the first direction A; wherein, L1 satisfies: 20mm≤L1≤30mm.

[0050] When the projection of the nursing section 21 onto the mounting surface 11 along the direction perpendicular to the mounting surface 11, and the length along the second direction B, is less than 20mm, the length of the nursing section 21 along the second direction B is small, making it difficult for the nursing surface 23 of the nursing section 21 to form a smooth arc effect, and the focusing ability of the nursing surface 23 for the nursing light is low. When the projection of the nursing section 21 onto the mounting surface 11 along the direction perpendicular to the mounting surface 11, and the length along the second direction B, is greater than 30mm, the length of the nursing section 21 along the second direction B is large, and the distance between the two ends of the nursing section 21 and the spray nozzle is too large, which may cause the user's hair to close up again before the spray nozzle reaches the exposed scalp. For example, L1 = 25mm.

[0051] Therefore, by limiting the projection of the nursing section 21 onto the mounting surface 11 along the direction perpendicular to the mounting surface 11 and the length range along the second direction B, it is easier for the nursing surface 23 of the nursing section 21 to form a smoother arc effect. At the same time, it ensures that the spray nozzle can quickly reach the exposed scalp, ensuring the nursing section 21's nursing effect on the user's scalp and improving the user's nursing experience.

[0052] Optionally, L2 satisfies: L2≤L1≤3L2. When the length of the care section 21 along the second direction B is less than the length of the care section 21 along the first direction A, the angle between the first contour line 24 and the second contour line 25 cannot form an acute angle, which may result in the two ends of the care section 21 not being able to separate the user's hair well. When the ratio of the length of the care section 21 along the second direction B to the length of the care section 21 along the first direction A is greater than 3, the length of the care section 21 along the second direction B is too large, which may result in the user's hair closing up again before the spray nozzle reaches the exposed scalp, making it impossible to effectively spray the care solution onto the user's scalp. For example, L1=2L2.

[0053] Therefore, by limiting the range of the ratio between the length of the care section 21 along the second direction B and the length of the care section 21 along the first direction A, it can be ensured that the angle between the first contour line 24 and the second contour line 25 is an acute angle, ensuring that the two ends of the care section 21 along the second direction B separate the user's hair, and at the same time, ensuring that the spray nozzle can spray the care solution onto the user's scalp, thereby improving the care effect of the comb teeth 100.

[0054] In this application, L1 satisfies: 20mm≤L1≤30mm, and L2 satisfies: L2≤L1≤3L2. Therefore, the ends of the care section 21 along the second direction B can be better formed into pointed tips, facilitating better separation of the user's hair by the ends of the care section 21.

[0055] According to some embodiments of this utility model, such as Figure 3 As shown, the comb 100 also includes a spray structure housed within the housing 10. The spray structure includes a nozzle 22, which is fitted into a spray nozzle opening. The nozzle 22 is adapted to spray the care solution inside the comb 100, and the nozzle 22 is detachably fitted into the spray nozzle opening. Thus, by fitting the nozzle 22 into the spray nozzle opening, the care solution inside the housing 10 can be sprayed onto the user's scalp through the nozzle 22, while simultaneously improving the integration and compactness of the first care structure 20.

[0056] According to some embodiments of this utility model, such as Figure 3 As shown, the nursing section 21 has a light-transmitting opening 26, which is located on at least one side of the spray nozzle along the second direction B, and the light-transmitting opening 26 extends through the nursing section 21 along the direction perpendicular to the mounting surface 11.

[0057] The light-transmitting port 26 penetrates the surface of the care section 21 away from the mounting surface 11 along a third direction C, and is spaced along a second direction B on the side of the spray nozzle away from the center area of ​​the care section 21. In this application, the care section 21 has two light-transmitting ports 26, which are respectively located near the two ends of the care section 21 along the second direction B, and the distance between the two light-transmitting ports 26 and the spray nozzle is the same. The light-transmitting ports 26 are suitable for irradiating the care light inside the housing 10 onto the user's scalp. Thus, by forming the light-transmitting port 26 on the care section 21, it is convenient to irradiate the user's scalp with the care light inside the housing 10 through the light-transmitting port 26, so that the user's scalp is simultaneously irradiated with light while the care solution is sprayed onto the user's scalp, promoting the scalp's absorption of the care solution and further improving the care effect of the comb 100.

[0058] According to some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, there are multiple first nursing structures 20, which are spaced apart along the first direction A; the comb teeth 100 also include multiple second nursing structures 30, which protrude from the mounting surface 11 and are staggered with the multiple first nursing structures 20 along the first direction A. The projection of the second nursing structure 30 along the direction perpendicular to the mounting surface 11 includes a third contour line 31 and a fourth contour line 32. The distance between the third contour line 31 and the fourth contour line 32 in the first direction A gradually decreases along the second direction B.

[0059] The nursing light inside the housing 10 can penetrate the second nursing structure 30. A plurality of first nursing structures 20 and a plurality of second nursing structures 30 are aligned and staggered along the first direction A. At least a portion of the second nursing structure 30 protrudes from the mounting surface 11 along the third direction C toward a direction away from the main housing 13 and forms a separable fit with the cover plate 12. The third contour line 31 and the fourth contour line 32 are both curved. The third contour line 31 and the fourth contour line 32 adjacent to the central region of the second nursing structure 30 are spaced apart along the first direction A. The third contour line 31 and the fourth contour line 32 away from the central region of the second nursing structure 30 along the second direction B extend obliquely along the first direction A toward a direction adjacent to each other and are connected to each other.

[0060] Therefore, by staggering multiple second care structures 30 with multiple first care structures 20 along the first direction A, the comb teeth 100 can easily care for multiple areas of the user's head, improving the care efficiency of the comb teeth 100. The distance between the third contour line 31 and the fourth contour line 32 of the second care structure 30 gradually decreases along the second direction B in the first direction A, making it easier for the two ends of the second care structure 30 to form sharp points along the second direction B. When the user uses the comb teeth 100, the two ends of the second care structure 30 can separate the user's hair and expose the scalp along the second direction B. The care light inside the shell 10 can penetrate the second care structure 30 and reach the user's scalp, thereby promoting the absorption of the care solution by the user's scalp and further improving the hair care and health care effect of the comb teeth 100.

[0061] Optionally, the second care structure 30 is recessed along the third direction C away from the housing 10 on the side surface of the second care structure 30 away from the housing 10 in the direction C toward the mounting surface 11 of the housing 10, and the side surface of the second care structure 30 away from the housing 10 along the third direction C is an arc-shaped surface, which facilitates the converging effect of the second care structure 30 on the care light, increases the light intensity, and thus further improves the care effect of the comb teeth 100.

[0062] Optionally, the first care structure 20 and the second care structure 30 have the same shape and size, improving the aesthetics and consistency of the comb tooth structure 100.

[0063] According to some embodiments of this utility model, such as Figure 6 As shown, the comb tooth 100 also includes: a lamp board structure 40, which is disposed inside the housing 10 and includes a plurality of lamp beads 41; some of the plurality of lamp beads 41 are respectively disposed opposite to the light-transmitting ports 26 of the plurality of first care structures 20.

[0064] A receiving cavity is defined between the cover plate 12 and the main housing 13. A mounting bracket is disposed within the receiving cavity. The lamp plate structure 40 is connected to the mounting bracket. Through holes or light guides are formed on the mounting bracket. The through holes or light guides are aligned with the light-transmitting ports 26 of the multiple first care structures 20 along a third direction C, so that the care light generated by the lamp beads 41 of the lamp plate structure 40 passes through the mounting bracket and illuminates the corresponding first care structure 20. Thus, by aligning a portion of the multiple lamp beads 41 with the light-transmitting ports 26 of the multiple first care structures 20, the loss of care light during the irradiation process is reduced. This facilitates the care light passing through the light-transmitting ports 26 and converging through the care surface 23 to illuminate the corresponding exposed scalp. Simultaneously, the spray nozzles of the first care structures 20 spray care liquid onto the exposed scalp, achieving synchronous irradiation of the scalp by care light and promoting the absorption of the care liquid.

[0065] Optionally, another portion of the plurality of LED beads 41 are respectively disposed opposite to the plurality of second care structures 30. The through holes or light guides are opposite to the plurality of second care structures 30 along the third direction C, so that the care light generated by the LED beads 41 of the light panel structure 40 passes through the mounting bracket and illuminates the corresponding second care structure 30, and is converged by the second care structure 30 on the side surface away from the housing 10 along the third direction C to illuminate the corresponding exposed scalp, thereby improving the hair care and hair strengthening effect of the comb teeth 100.

[0066] In this application, some of the multiple LED beads 41 are respectively positioned opposite to the light-transmitting ports 26 of the multiple first care structures 20, while other portions of the multiple LED beads 41 are respectively positioned opposite to the multiple second care structures 30. This further improves the care effect of the comb teeth 100 and reduces light loss during the care process.

[0067] According to some embodiments of this utility model, the second care structure 30 is a light-transmitting element. This allows the care light generated by the opposing LED beads 41 of the multiple second care structures 30 to directly pass through the second care structure 30, increasing the area illuminated by the care light, reducing light loss during the irradiation process, and facilitating direct observation of the working status of the comb teeth 100 by the user.

[0068] The nursing comb according to a second aspect of the present invention includes the comb teeth 100 as described in any of the above embodiments.

[0069] By employing a comb 100 comprising a first care structure 20 and a second care structure 30, both ends of the first care structure 20 and the second care structure 30 are formed with pointed tips along the second direction B. The first care structure 20 is provided with a spray nozzle and a light-transmitting port 26, which facilitates the first care structure 20 to separate the user's hair and expose the scalp along the second direction B. The spray nozzle directly sprays care liquid onto the exposed scalp, and the care light inside the comb 100 simultaneously irradiates the exposed scalp, promoting the absorption of the care liquid. At the same time, the surfaces of the first care structure 20 and the second care structure 30 along the third direction C away from the housing 10 are recessed towards the mounting surface 11 of the housing 10 along the third direction C, and both are arc-shaped surfaces, which can converge the care light, increase the light intensity, and effectively improve the care effect and reliability of the care comb.
