Description

Technical Field

[0001] This invention relates to the field of hair styling tools, and more particularly to a professional comb with an innovative composite comb tooth structure and an anti-hair-snagging handle structure. Specifically, this invention provides a modular comb head structure, an anti-hair-snagging handle structure, and an arc-shaped professional comb comprising at least one of the above structures. Background Technology

[0002] Hairbrushes are essential tools for professional hairstylists and individuals alike for styling, combing, and drying hair daily. An excellent hairbrush should be efficient at drying hair, allow for precise styling, protect hair quality, and be comfortable to hold. To improve drying efficiency and styling results, various combs with different bristle arrangements and ventilation designs have emerged on the market.

[0003] Currently, professional hair combs on the market are primarily designed around combing functionality and handle ergonomics. For combing, common features include nylon bristles, boar bristles, or simple combinations thereof, with ventilation holes or channels in the comb body to achieve the goals of gripping, protecting, and accelerating hair drying. For the handle, to improve grip and comfort, a process is generally used where an ABS plastic body is double-injected or coated with soft materials such as TPR.

[0004] However, these existing technologies in this field still have significant limitations. First, in terms of combing function, most products have a relatively simple comb tooth structure, and the layout of different functional comb teeth fails to achieve optimal coordination, resulting in insufficient hair grip and easy hair scattering during blow-drying and styling. At the same time, their ventilation design is often relatively simple, encountering a bottleneck in improving hair drying efficiency. Second, and more challenging, is the handle connection structure: existing processes generally use soft rubber to join the hard body at a planar boundary. This planar connection method has inherent defects: firstly, tiny gaps are easily generated at the seam, and when the user combs quickly, the hair can be caught and stuck in the gap, leading to hair breakage, scalp injury, and a very poor user experience and safety risks; secondly, this structure relies on the strength of the adhesive bond, and with long-term use or slight deviations in the injection molding process, the soft rubber layer is prone to loosening or even falling off, seriously affecting the product's durability and reliability.

[0005] Therefore, there is an urgent need in this field for a comprehensive and innovative solution that can significantly improve hair-grabbing effect, ventilation efficiency, and styling function by optimizing the arrangement and combination of comb teeth, and fundamentally improve the connection method of the handle from a physical structure perspective, completely solving the industry pain points of hair getting stuck and instability, thereby providing a professional hair comb that is efficient, reliable, safe, and offers an excellent user experience. Summary of the Invention

[0006] The main objective of this invention is to provide a high-performance professional comb solution, specifically: 1) to improve ventilation efficiency and styling accuracy through a modular comb head structure design; 2) to completely solve the safety hazard of hair getting caught in traditional combs through a brand-new handle connection structure; and 3) to provide a product solution that can be flexibly combined and provides comprehensive protection to adapt to diverse production needs and build a robust patent protection network.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: In a first aspect, the present invention provides a modular comb structure for use in professional combs, comprising: three main comb bodies, each main comb body including two arc-shaped comb bodies, the two arc-shaped comb bodies of the same main comb body being connected at their ends by a smooth transition structure, thereby forming six arc-shaped comb bodies; a first hollow area is formed between the two arc-shaped comb bodies of the same main comb body, and a second hollow area is formed between two adjacent main comb bodies; each arc-shaped comb body is provided with a row of regularly arranged soft comb teeth, and the connecting line at the top of each row of soft comb teeth together outlines a smooth macroscopic arc curve that matches the curvature of the human skull; the soft comb teeth include columnar comb teeth, nylon filaments and boar bristle filaments; a row of hard comb teeth is provided in the first hollow area and the second hollow area respectively, and the adjacent rows of hard comb teeth are staggered. Furthermore, the hard comb teeth are serrated, with a smooth transition at the top. Furthermore, the smooth transition structure is an arc-shaped curved surface. Furthermore, the nylon filament has a length of 16.5 mm and a diameter of 0.8 mm, and the pig bristle filament has a length of 12 mm. Furthermore, the number of soft comb teeth assemblies is 114. Furthermore, the number of hard comb teeth is 54. Secondly, the present invention provides an anti-hair-snagging handle structure for use in professional combs, comprising an ABS body and a TPR coated handle, wherein the connecting surface between the ABS body and the TPR coated handle is a wavy curved surface, and the ABS body and the TPR coated handle are interlocked and fixed by a tenon and mortise structure. Furthermore, the tenon and mortise structure includes a recess on the ABS body and a protrusion on the TPR overmolded handle that is interference-fitted with the recess. Furthermore, the end of the handle structure is also provided with a detachable tail pin. Furthermore, the TPR-coated handle is wrapped around the ABS body using a rubber-coating process. Thirdly, the present invention provides an arc-shaped professional comb, including the comb head structure described in the first aspect and the handle structure described in the second aspect, wherein the comb body of the comb head structure and the ABS body of the handle structure are integrally formed. Furthermore, the first hollow area is waist-shaped, and the sidewall of the first hollow area forms a gradually narrowing air guide surface.

[0008] Compared with the prior art, the technical solution provided by the present invention has the following significant advantages: 1. Superior Drying and Styling Performance: The modular design of the comb body creates a systematic ventilation channel, especially the first hollow area in the waist shape and its air guide surface, which can efficiently guide airflow and significantly shorten drying time. The combination of the zoned layout of soft and hard comb teeth and the staggered arrangement of hard comb teeth gives the comb multiple functions, including basic combing, strong hair gripping, hair nourishing and protection, and precise styling, making it a comprehensive performer.

[0009] 2. Significantly Enhanced Safety and Durability: The wavy connecting surface of the handle structure, combined with the mortise and tenon joint, eliminates the possibility of hair getting stuck, ensuring user safety. The mechanical interlocking structure ensures an extremely secure connection, resulting in a product lifespan and reliability far exceeding that of traditional rubber-coated combs.

[0014] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0015] Example 1: Modular comb head structure This embodiment describes in detail the innovative comb head structure 100 of the present invention for use in professional combs.

[0016] See Figures 1 to 4 The comb structure 100 employs an unprecedented modular composite architecture. Its foundation consists of three identical comb body bodies 50 arranged circumferentially to form a 36mm diameter columnar structure, which is then fixed together by a connecting structure. This modular design not only facilitates production and assembly but also creates excellent partitioning functionality.

[0017] Each comb body 50 is an independent functional unit, preferably integrally molded from a high-temperature resistant, high-strength engineering plastic (such as PPS or high-temperature resistant nylon) through precision injection molding. Each unit is approximately waist-shaped and contains two parallel, inwardly curved arc-shaped comb bodies 10. These two arc-shaped comb bodies 10 are not independent but are smoothly connected at their ends by a smooth transition structure 60. This smooth transition structure 60 is preferably an ergonomically optimized arc surface with a radius of curvature to ensure that it can glide smoothly over the scalp without causing any pulling or discomfort. When three such functional units are combined, they form six equally spaced arc-shaped comb bodies 10, which together constitute the main framework of the comb structure 100.

[0018] This unique layout naturally creates two types of ventilation channels: First hollow area 31: This refers to the space within the same comb body 50, enclosed by its two arc-shaped comb bodies 10. This area is usually long and regular.

[0019] Second hollow area 32: This refers to the space between two adjacent comb body main bodies 50, formed by two adjacent arc-shaped comb bodies 10 belonging to two different units.

[0020] On the top curved surface of each of the arc-shaped comb bodies 10, a row of soft comb teeth 20 is embedded at fixed, regular intervals. The connecting line at the top of all the soft comb teeth 20 together outlines a smooth macroscopic arc curve 24 that matches the curvature of the human skull, ensuring a large-area uniform fit during combing and providing excellent comfort. The soft comb teeth 20 are not made of a single material, but are a functional composite. They include: Columnar comb teeth 23: provide basic support and combing force to ensure the stability of the comb tooth matrix; Nylon filament 21: Preferably a rigid nylon filament with a diameter of 0.8 mm and a length of 16.5 mm, which has excellent elasticity and hair-gripping power and can effectively hold the hair strand firmly; Boar bristle 22: Preferred to be 100% natural boar bristles with a length of 12mm. Its cuticle structure can absorb and evenly distribute scalp oil, effectively smoothing hair cuticles, reducing frizz, and adding shine.

[0021] These comb teeth made of different materials can be mixed and distributed in any proportion and pattern. For example, a cluster of nylon / bristle composite filaments can be provided every two columnar comb teeth 23, or preferably, each columnar comb tooth 23 can be combined with a cluster of nylon filaments 21 and a cluster of bristle filaments 22. In a most preferred embodiment, the total number of soft comb teeth 20 on the entire comb structure 100 is exactly 114.

[0022] In the center of each of the first hollowed-out areas 31 and the second hollowed-out area 32, a row of hard comb teeth 40 is vertically arranged. The hard comb teeth 40 are preferably serrated, and their surfaces can be designed with fine textured surfaces to further enhance their gripping ability. One of the most crucial features of this invention is that all adjacent rows of hard comb teeth 40 are staggered along the length of the comb, i.e., staggered arrangement. Specifically, the teeth of rows 1, 3, and 5 are aligned, and the teeth of rows 2, 4, and 6 are aligned, but these two groups are staggered. This design ensures that whether the comb is rotated clockwise or counterclockwise for curling, multiple hard comb teeth can firmly grip the hair from different angles, significantly improving styling success rate and efficiency. In one specific embodiment, the total number of hard comb teeth 40 is 54. To avoid scratching the hair during combing, the heads of the columnar comb teeth 23 and the hard comb teeth 40 are designed with a smooth transition structure.

[0023] Furthermore, the first hollowed-out area 31 is specially designed in a waist shape (or dumbbell shape). Its sidewalls are not straight up and down, but are processed into air guide surfaces 311 that gradually taper inward. The air guide surface 311 functions similarly to a nozzle. When the airflow from the hair dryer passes through it, it can generate a Venturi effect, accelerating the airflow and making it more concentrated on the hair strands, thereby greatly improving drying efficiency.

[0024] Example 2: Anti-jamming handle structure This embodiment describes in detail the innovative handle structure 200 of the present invention for use in professional combs.

[0025] See Figures 5 to 7 The revolutionary aspect of the handle structure 200 lies in its complete solution to the problem of hair getting stuck, from the perspectives of structural mechanics and materials science.

[0026] The handle structure 200 is made of two materials: an ABS body 201 and a TPR-coated handle 202. The ABS body 201 provides a rigid frame for the entire handle, ensuring it is not easily deformed when held, and its excellent heat resistance can also withstand the hot air from the hair dryer. The TPR-coated handle 202 covers the area where the hand grips, providing a soft, skin-friendly, and high-friction feel to prevent slipping during operation.

[0027] Its core innovation lies in the interface and method of connection between the two: The wavy connecting surface 203: The parting surface (i.e., contact interface) between the ABS body 201 and the TPR-coated handle 202 is not a traditional simple straight line or plane. This invention designs it as a continuous, smoothly undulating three-dimensional wavy surface (e.g., a sine curve, cloud shape, or freeform surface). The advantage of this surface is that it completely eliminates the linear, continuous gaps that could cause hair to get stuck. Even if a hair comes into contact with this area, it will slide past the surface and not get stuck.

[0028] Mortise and tenon joint structure: To ensure ultra-high reliability of the connection, this invention introduces the traditional mortise and tenon concept based on the wavy connecting surface 203. Specifically, multiple recesses 201a (which can be used as "mortises") are formed at predetermined positions on the ABS body 201. During the secondary injection molding of TPR, the molten TPR material fills these recesses 201a, and after cooling, it forms protrusions 202a (which can be used as "tenons") that perfectly match its shape. The protrusions 202a and the recesses 201a are interference-fitted, generating a huge frictional force. The bonding force provided by this mechanical interlocking structure is far superior to that of simple chemical adhesives, making it almost impossible for the TPR-coated handle 202 to twist or axially displace relative to the ABS body 201, fundamentally solving the problem of loosening and falling off.

[0029] The TPR-coated handle 202 can be perfectly wrapped around the ABS body 201 through a molding process (i.e., secondary injection molding), forming a sturdy whole. Alternatively, a positioning flange 201b can be designed on the ABS body 201, and a corresponding positioning groove (not shown in the figure) can be designed on the TPR-coated handle 202. The positioning flange 201 and the positioning groove cooperate to achieve positioning and detachable assembly. For easy gripping, the TPR-coated handle 202 can also be designed with anti-slip textures 202b. A hanging hole 202c can also be designed at the tail of the TPR-coated handle 202 for convenient hanging and storage of the comb.

[0030] In addition, a detachable tail pin 204 is embedded at the end of the handle structure 200. This tail pin 204 is typically made of ABS and has a slightly thinner tip, allowing it to be easily inserted between the comb teeth to hook out and clean tangled hair and dandruff, greatly facilitating daily maintenance.

[0031] Example 3: Curved Professional Comb Product This embodiment combines the above-mentioned innovative components to describe the structural details of the arc-shaped professional comb product of the present invention.

[0032] See Figures 8-9 The arc-shaped professional comb of this embodiment is the culmination of the modular comb head structure 100 of Embodiment 1 and the anti-hair-snagging handle structure 200 of Embodiment 2. The comb body 50 of the comb head structure 100 and the ABS body 201 of the handle structure 200 can be integrally molded by injection molding, while the TPR-coated handle 202 is injection molded separately. The two are assembled and fixed together. To improve the connection strength, adhesive can be added for reinforcement between the body and the TPR-coated handle 202.

[0033] The overall length, weight distribution, and center of gravity of the product have been precisely calculated ergonomically to ensure that professional hairstylists will not feel fatigued even after prolonged, high-frequency use. The non-slip, comfortable grip of the handle structure 200 complements the efficient performance of the comb structure 100.

[0034] In actual use, the user enjoys a comfortable grip on the handle structure 200. The comb structure 100's curved soft comb teeth 20 matrix gently conforms to the scalp, with nylon filaments 21 providing strong grip and boar bristle filaments 22 caring for the hair. The airflow of the hair dryer is efficiently guided through the air guide surface 311 of the first hollow area 31 and the second hollow area 32, quickly removing moisture. When styling is needed, the user simply rotates the comb, and the staggered serrated hard comb teeth 40 grip the hair at the optimal angle, easily completing complex operations such as inward curls, outward curls, and straightening. Throughout the process, there is no need to worry about the handle getting stuck on the hair, providing a smooth, safe, and efficient user experience.

[0035] It should be noted that, according to the scope of protection set forth in the independent claims of this invention, the protection of this invention also extends to combs that employ only the aforementioned innovative comb head structure 100 (with a standard handle), or combs that employ only the aforementioned innovative handle structure 200 (with a standard comb head). This provides great flexibility for diversified product manufacturing and marketing strategies, while also providing the broadest legal basis for patent protection.
