[0002] A blow-dryer is a technological product that provides air at a specific temperature to meet the needs of combing and conditioning hair. It can dry hair while combing it, providing some conditioning benefits. However, most existing blow-dryer designs have triangular bristles, which cannot conform well to the curved contours of the head. This makes it difficult to distribute combing force effectively and comb hair evenly, resulting in relatively poor combing results and causing some areas to be neglected or not combed sufficiently.

Therefore, they should not be construed as limitations on the present application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0040] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0041] like Figures 1 to 9As shown, according to the first aspect of this application, this application provides a hair comb structure 100, which is mainly used in electric hair combs. The hair comb structure 100 includes a body 10 and comb teeth 20. The body 10 has a first fluid cavity 11 extending through it. The comb teeth 20 are disposed on one side of the body 10. A second fluid cavity 21 communicating with the first fluid cavity 11 extends through the comb teeth 20. The fluid outflow direction of the second fluid cavity 21 is parallel to the fluid inflow direction of the first fluid cavity 11, realizing directional fluid transmission and reducing turbulence loss. The comb teeth 20 have an inflection point 22 at their extended ends. The front and rear sections of the inflection point 22 are continuous but not parallel. When caring for hair, a lever can be formed at the inflection point 22, which is more ergonomic and easier to use, while also providing better combing and hair care effects, reducing the possibility of hair damage and breakage. Here, the fluid is airflow.

[0042] For example, since the front and rear segments of the inflection point 22 are continuous and non-parallel, the comb teeth 20 can have various structural forms such as bending, folding, right angle or step on the outer wall of the extension end. The curvature of the comb teeth 20 on the outer wall of the extension end can change continuously. That is, the comb teeth 20 can have at least one inflection point 22 on the outer wall of the extension end to form an involute or zigzag transition structure, which is more comfortable to use and requires less effort.

[0043] Specifically, in order to improve the drying efficiency of hair roots close to the scalp, it is usually necessary to rotate the comb teeth 20 to lift the hair roots. This usually requires a large angle of rotation, which is not conducive to the operator. In this solution, the inflection point 22 is used as the fulcrum, and the front end of the comb teeth 20 forms a lever with the handle, so as to lift the hair with a very small angle of rotation, which saves effort and is easy to operate. Here, the handle refers to the main body 10 or the extension connection end / connection hand end of the main body 10.

[0044] The cross-sectional dimensions of the comb teeth 20 gradually decrease from the end closest to the body 10 toward the end furthest from the body 10. The outer wall of the comb teeth 20 has an inwardly recessed arc-shaped portion 23 from the inflection point 22 to the far end to match the human head, so that it can fit the user's head more closely during use, and has a better combing and hair care effect. While ensuring the uniformity of airflow, it achieves a self-adaptive fit to the head. The inflection point 22 and the arc-shaped portion 23 are respectively located on the upper and lower sides of the outer wall of the comb teeth 20.

[0045] By adopting the above technical solution, since the comb teeth 20 gradually taper from the end closest to the body 10 to the end furthest from the body 10, it can not only reduce the contact area with the hair and reduce frictional resistance, but also reduce wind resistance, optimize fluid distribution, balance fluid pressure, and avoid excessive local airflow. Specifically, the comb teeth 20 are bent along a preset direction to form the arc-shaped portion 23 that matches the curvature of the head contour. This reduces overall weight, avoids a bulky appearance, and conforms to changes in head curvature, thus achieving a seamless fit with the head. Through the combination of fluid dynamics and ergonomics, it ensures uniform airflow while achieving adaptive head fit, solving the problems of uneven fluid distribution and poor fit in traditional hair combs.

[0046] In an optional embodiment, the first fluid cavity 11 has a fluid inlet 111 at the end away from the second fluid cavity 21, and the second fluid cavity 21 has a fluid outlet 211 at the end away from the first fluid cavity 11. This allows fluid to enter the first fluid cavity 11 from the fluid inlet 111 and then enter the second fluid cavity 21, and then exit from the fluid outlet 211. This allows the comb structure 100 to blow up the hair while combing it, making the hair smooth, preventing tangles, facilitating combing and drying, and providing a certain degree of hair care.

[0047] The fluid outlet 211 is located on the side wall of the second fluid cavity 21 and is in the same or opposite direction to the extension direction of the body 10, so that the fluid can enter the first fluid cavity 11 from the fluid inlet 111 of the body 10, and then enter the second fluid cavity 21 of the comb teeth 20 from the first fluid cavity 11, and finally exit from the fluid outlet 211 on the side wall of the second fluid cavity 21, so as to achieve low loss transmission and allow the fluid to flow along the surface of the scalp or hair, avoiding discomfort caused by vertical spray.

[0048] In this embodiment, the ratio of the maximum radius R of the arc-shaped portion 23 to the extension length L of the comb teeth 20 is greater than 2 and less than or equal to 2.5, which ensures a smooth arc transition and prevents the comb teeth 20 from being too straight and losing their fit.

[0049] For example, when the ratio of the maximum radius R of the arc-shaped portion 23 to the extension length L of the comb teeth 20 is greater than 2, the curvature of the arc-shaped portion 23 can be ensured to be sufficiently gentle, preventing the comb teeth 20 from bending excessively, which could cause the fluid outlet 211 angle to deviate from the head or result in insufficient structural strength. When the ratio of the maximum radius R of the arc-shaped portion 23 to the extension length L of the comb teeth 20 is not greater than 2.5, excessive straightness of the arc-shaped portion 23 can be limited, preventing it from achieving a close fit with the head contour. The head curvature radius of adults is generally in the range of 90-120mm, such as in the occipital region. Therefore, by limiting the ratio of the maximum radius R of the arc-shaped portion 23 to the extension length L of the comb teeth 20, this application allows the arc-shaped portion 23 in the comb teeth 20 to match the head curvature of most users, reducing the frequency of manual adjustments. Furthermore, the arc-shaped portion 23 within this ratio range can not only reduce the turbulent loss of fluid within the comb teeth 20 and ensure the uniformity of the air velocity at the fluid outlet 211, but also be achieved through conventional mold core-pulling process, so that its demolding angle can be maintained at 1 to 2 degrees, ensuring the product yield rate and achieving a balance between ergonomic fit, fluid efficiency and structural reliability.

[0050] In an optional implementation, the central angle corresponding to the arc-shaped portion 23 is within the range of 20 to 30 degrees to provide compatibility for extreme head shapes, such as children or special hairstyles; it also allows the fluid direction of the fluid outlet 211 to have an angle ≤15° with the scalp normal, reducing fluid scattering loss and improving wind energy utilization. The central angle refers to the angle formed by the lines connecting the two endpoints to the center of the arc-shaped segment of the comb teeth 20. In this embodiment, the central angle corresponding to the arc-shaped portion 23 is limited to between 20 and 30 degrees, which covers the theoretical calculation value while allowing for process errors, such as the influence of injection molding shrinkage, thus ensuring the product yield.

[0051] In this embodiment, the second fluid cavity 21 includes at least one first flow channel 212 entering from the first fluid cavity 11 and at least one second flow channel 213 outflowing from the fluid. The first flow channel 212 and the corresponding second flow channel 213 are connected. The first flow channel 212 and the second flow channel 213 are not parallel to each other, so that the fluid can be redirected in the second fluid cavity 21 to achieve directional fluid transport and reduce turbulence loss.

[0052] In an alternative embodiment, the first flow channel 212 and the second flow channel 213 are both perpendicular to each other, so that the fluid flows along the surface of the scalp or hair and avoids discomfort caused by vertical spraying.

[0053] In an optional embodiment, the ratio of the maximum width W of the second fluid cavity 21 to the maximum inner diameter D of the first fluid cavity 11 is greater than 0.5 and less than or equal to 1. This resolves the contradiction between miniaturization and efficient air delivery through a collaborative design of fluid mechanics and structural mechanics. A gradually widening section is formed between the first fluid cavity 11 and the second fluid cavity 21 to reduce the fluid velocity, convert kinetic energy into static pressure, and reduce outlet whistling noise.

[0054] In this embodiment, the comb structure 100 further includes an air guide 30, which is disposed inside the first fluid cavity 11. The air guide 30 is used to guide the fluid in the first fluid cavity 11 to the second fluid cavity 21. The fluid enters the second fluid cavity 21 from the inlet of the first fluid cavity 11 through the air guide 30 and flows out from the fluid outlet 211 of the second fluid cavity 21, making the fluid output by the comb more uniform, the hair more evenly exposed to air, and speeding up the drying of the hair, resulting in better performance.

[0055] The air guide 30 includes a base frame 31, a rotating shaft 32, and multiple spaced arc-shaped plates 33. The multiple arc-shaped plates 33 are all connected to the base frame 31, and the rotating shaft 32 protrudes from the base frame 31. The base frame 31 and the arc-shaped plates 33 are all located inside the first fluid cavity 11. The body 10 is also provided with a rotating hole 12 that communicates with the first fluid cavity 11. After the rotating shaft 32 passes through the rotating hole 12, it is located outside the body 10. The shapes of each arc-shaped plate 33 are basically the same, only their sizes are different. With the cooperation of the base frame 31, the multiple arc-shaped plates 33 can divide the turbulence from the fluid inlet 111 into multiple parallel flows to reduce the turbulence intensity, ensure the basic uniformity of the fluid, and make the fluid smoothly turn towards the direction of the comb teeth 20 to change the direction of the fluid, so that the fluid can flow into the second fluid cavity 21 evenly.

[0056] The fluid outlet 211 of the second fluid cavity 21 is provided with an extended guide 24 on its outer periphery. The guide 24 is arranged perpendicularly to the fluid outlet 211 and is used to guide the direction of fluid blowing so that the fluid can be redirected in the second fluid cavity 21 to achieve directional fluid transmission. The guide 24 can be an extension or a spiral.

[0057] In this embodiment, the comb structure 100 further includes an adjustment component 40. The main body 10 is also provided with an exhaust port 13 communicating with the second fluid cavity 21. The exhaust port 13 and the comb teeth 20 are located on opposite sides of the main body 10. The adjustment component 40 is connected to the air guide 30. Specifically, the adjustment component 40 is located outside the main body 10 and is connected to the rotating shaft 32. The adjustment component 40 can control the air guide 30 to rotate relative to the main body 10. The adjustment component 40 can adjust the flow of fluid from the fluid outlet 211 of the second fluid cavity 21 or from the exhaust port 13 through the air guide 30, so as to change the direction of the fluid in the first fluid cavity 11.

[0058] In an optional embodiment, the adjustment assembly 40 includes a knob cap 41 and a knob cover 42. The rotating shaft 32 is connected to the knob cover 42. The knob cap 41 is disposed on the knob cover 42 to limit the rotation of the knob cover 42. An elastic element 43 and a positioning pin 44 are provided between the knob cover 42 and the knob cap 41. The positioning pin 44 is mounted on the knob cover 42. The elastic element 43 always maintains an elastic force in the direction of the knob cap 41 to drive the positioning pin 44 to abut against the knob cap 41, so that the knob cap 41 remains relatively unchanged relative to the body 10 when no force is applied. The elastic element 43 is a spring.

[0059] The air comb structure 100 also includes a motor and a control unit connected to the adjustment component 40. The control unit can drive the air guide 30 to rotate forward or backward by 180 degrees, and adjust the fluid to flow out from the fluid outlet 211 of the second fluid chamber 21 or from the exhaust port 13.

[0060] In this embodiment, the comb teeth 20 include a connecting frame 25 and a plurality of tooth plates 26 that are evenly spaced and protruding on the connecting frame 25. The connecting frame 25 is snapped onto the body 10. The first flow channel 212 passes through the connecting frame 25 and extends recessed toward the center of the tooth plate 26. The second flow channel 213 passes through the center of the tooth plate 26 to the outer wall of the tooth plate 26, thereby realizing precise fluid distribution and multi-functional care.

[0061] Multiple toothed plates 26 include multiple outer comb teeth 261 and at least one inner comb tooth 262 disposed between the outer comb teeth 261. When the comb tooth 20 is a round comb, the inner comb tooth 262 is surrounded by outer comb teeth 261. Both the inner comb tooth 262 and the outer comb tooth 261 protrude from the connecting frame 25. The outer comb tooth 261 has a fluid outlet 211 facing the inner comb tooth 262, and the inner comb tooth 262 has a fluid outlet 211 facing the outer comb tooth 261.

[0062] When the comb teeth 20 are handleless combs, there are two outer comb teeth 261 and multiple inner comb teeth 262. The multiple inner comb teeth 262 are mainly distributed between the two outer comb teeth 261, so as to form a fluid clamping effect by using the double-sided air outlet as the main channel and the single-sided air outlet towards the center, thereby enhancing the fluid penetration on both sides of the scalp.

[0063] The first flow channel 212 can be a cavity inside the comb tooth 20 near the first fluid cavity 11. Each first flow channel 212 can be paired with at least one second flow channel 213. The outer comb tooth 261 can have only one second flow channel 213, and the inner comb tooth 262 can have two second flow channels 213. The two second flow channels 213 can be two isolated chambers on the left and right sides of the comb tooth 20 away from the first fluid cavity 11. The fluid blowing against each other between the inner comb teeth 262 can effectively form turbulence, accelerate hair drying efficiency, and effectively reduce airflow attenuation in the fluid.

[0064] In an optional embodiment, the comb teeth 20 are provided with multiple baffles 27 at intervals inside, and air guide holes 28 are formed between two adjacent baffles 27. The air guide holes 28 are connected to the second fluid cavity 21, which can not only prevent the hair from being blown directly, but also allow the fluid to generate a Venturi effect when passing through the air guide holes 28, thereby increasing the flow rate and ensuring that the fluid is accurately directed to the hair roots or the target area of ​​the scalp.

[0065] In one optional embodiment, the gap between two adjacent toothed plates 26 is 2-3 mm, so that some hair can smoothly enter between the two adjacent toothed plates 26 and is not easily detached from between the two adjacent toothed plates 26, which plays a certain binding role and enhances the permeability of fluid to hair.

[0066] The comb structure 100 also includes a positioning plate 50, a disassembly part 29 on the connecting frame 25, and an installation notch on the body 10 that matches the disassembly part 29, so that the positioning plate 50 can fix the disassembly part 29 in the installation notch, thereby realizing the detachable connection between the comb teeth 20 and the body 10.

[0067] This utility model also discloses an electric hair dryer, including a hair dryer 200 and a hair dryer structure 100 as described above, wherein the hair dryer 200 is connected to the fluid inlet 111 of the first fluid chamber 11.
