Description

Technical Field

[0001] This utility model relates to the field of hair styling equipment technology, and in particular discloses an airflow channel structure for a hair comb. Background Technology

[0002] In the hair styling tool market, blow-dry combs are a powerful tool for daily hair styling, but their existing technology has many shortcomings, severely limiting user experience and styling results. The heat conduction technology of traditional blow-dry combs has obvious drawbacks. On the one hand, the heat conduction efficiency is poor; airflow cannot quickly reach key heat-conducting components, resulting in long preheating times and inconvenience. On the other hand, the heat conduction uniformity is poor; uneven heating occurs across different parts of the heat conduction components. During hair styling, localized overheating can damage hair, while localized undercooling makes it difficult to achieve the desired styling effect, failing to meet users' demands for safe and efficient hair styling.

[0003] The airflow channel and structural design also have flaws. The airflow channel design is unreasonable, resulting in turbulent airflow that cannot be concentrated and directed, leading to poor blowing performance and failing to meet the requirements for rapid drying and precise styling. The comb tooth layout is incompatible with the airflow channel, preventing them from working together. Furthermore, the overall structural stability is weak, making it prone to deformation and damage due to uneven stress during use, thus shortening its service life. In addition, the assembly process is complex, with poor positioning and connection design, increasing production difficulty and cost, and easily leading to assembly errors that affect performance. Airflow leakage is common during use, resulting in low thermal efficiency, and the internal components lack effective protection, making them susceptible to damage from dust and moisture. Utility Model Content

[0004] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide an airflow channel structure for a comb head.

[0005] To achieve the above objectives, the present invention provides an airflow channel structure for a comb head, comprising a bristle-planting frame and a heat-conducting component used in conjunction with the bristle-planting frame. The bristle-planting frame has a first through hole, and the heat-conducting component has a second through hole. The bristle-planting frame forms a cavity, and an air passage gap for conveying airflow is formed between the bristle-planting frame and the heat-conducting component. The heat-conducting component covers the first through hole. The airflow in the cavity is sequentially blown out of the heat-conducting component through the first through hole, the air passage gap, and the second through hole.

[0006] Furthermore, the hair-planting frame is also equipped with blind holes for comb teeth, and comb teeth are installed inside the blind holes for comb teeth, with the comb teeth protruding out of the heat conduction component through the second through hole.

[0007] Furthermore, the surface of the flocking frame facing away from the cavity protrudes towards the heat conduction component to form a guide strip. The guide strip is arranged along the length of the heat conduction component, and the number of guide strips is set to multiple. The multiple guide strips are arranged around the central axis of the flocking frame. The multiple guide strips are located in the air gap and divide it into different airflow channels. The multiple guide strips abut against the inner surface of the heat conduction component.

[0008] Furthermore, the number of the first through hole, the comb tooth blind hole, and the second through hole are all set to be multiple. Multiple first through holes are arranged along the length direction of the hair-planting frame to form a first hole group, multiple comb tooth blind holes are arranged along the length direction of the hair-planting frame to form a blind hole group, and multiple second through holes are arranged along the length direction of the heat-conducting component to form a second hole group.

[0009] Furthermore, the number of the first hole group, the second hole group, and the blind hole group are all set to be multiple. The multiple first hole groups and the multiple blind hole groups are arranged around the central axis of the hair-planting frame, and the multiple second hole groups are arranged around the central axis of the heat-conducting component.

[0010] Furthermore, the second through hole is aligned with the blind hole of the comb teeth, and the diameter of the second through hole is larger than the diameter of the blind hole of the comb teeth.

[0011] Furthermore, the tail end of the hair-planting frame is provided with an end shell, and the air inlet end of the hair-planting frame is provided with a mounting part for mounting the hair-planting frame on the comb head body.

[0012] Furthermore, the end shell has a locking block, and the tail end of the flocking frame has a locking groove that engages with the locking block. The number of locking blocks and locking grooves is set to be multiple, and there is a one-to-one correspondence between the locking blocks and the locking grooves. The multiple locking blocks and multiple locking grooves are arranged around the central axis of the flocking frame.

[0013] Furthermore, the end shell covers the heat conduction component, thus limiting one end of the heat conduction component. The side of the hair-planting frame near the mounting part protrudes in the direction away from the cavity to form a limiting protrusion for limiting the other end of the heat conduction component. The heat conduction component is provided with a limiting hole that cooperates with the limiting protrusion. The end shell cooperates with the limiting protrusion to limit both ends of the heat conduction component.

[0014] Furthermore, the heat conduction element is a thin-walled tubular structure with openings at both ends, and the heat conduction element is made of aluminum or stainless steel with a thickness of 1 to 3 mm.

[0015] The beneficial effects of this utility model are:

[0016] Highly efficient and uniform heat conduction: The airflow inside the cavity passes through the first through hole, the air gap and the second through hole and blows out of the heat conduction component. The meandering flow channel allows the hot air to act on the hair frame and heat conduction component for a longer time to maintain heat, so that the heat dissipation is slower and the heat conduction component conducts heat evenly as a whole. Finally, the heat is blown out along the direction of the comb teeth and acts on the hair, improving the full utilization of heat.

[0017] Optimized airflow and structure: The air guide strip guides the airflow in an orderly manner, and the multiple sets of holes are arranged in a regular manner to ensure that the airflow is blown out evenly. All components work together to improve heat conduction and air blowing effect, enhance structural stability, and extend service life.

[0018] Easy assembly and practicality: The design of the end shell, mounting part, and limiting structure simplifies the installation process, improves assembly efficiency and accuracy, prevents hot air leakage, ensures the normal functioning of the comb head, and enhances practicality and user experience.

[0026] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0027] Please see Figures 1 to 6 As shown, the airflow channel structure of a comb head according to this utility model includes a hair-planting frame 1 and a heat-conducting component 2 used in conjunction with the hair-planting frame 1. The hair-planting frame 1 is provided with a first through hole 11, and the heat-conducting component 2 is provided with a second through hole 21. The hair-planting frame 1 forms a cavity, and an air passage gap 6 is provided between the hair-planting frame 1 and the heat-conducting component 2 to form an air passage for conveying airflow. The heat-conducting component 2 covers the first through hole 11. The airflow in the cavity is blown out of the heat-conducting component 2 through the first through hole 11, the air passage gap 6, and the second through hole 21 in sequence.

[0028] In actual use, by setting specific airflow channels, namely the first through hole 11, the air gap 6, and the second through hole 21, the airflow inside the cavity can be blown out of the heat conduction component 2 along the designed path. This allows for precise guidance of the airflow to the required location; for example, when combing hair, it can accurately act on the hair surface, improving the efficiency of airflow utilization. The presence of the air gap 6 helps stabilize the airflow, reducing airflow turbulence and fluctuations. This makes the blown airflow more uniform and stable, thus providing consistent wind force and direction when drying or styling hair, improving the overall performance.

[0029] Because the airflow can be evenly distributed on the surface of the heat conduction component 2 and blown out, the hair can be evenly heated and aired during the drying process, avoiding localized over-drying or incomplete drying, effectively improving the quality and speed of hair drying. The combined use of the hair grafting frame 1 and the heat conduction component 2 makes the entire airflow channel structure compact and reasonable, meeting the functional requirements of airflow delivery without occupying too much space. This makes the hair dryer comb head more lightweight, compact, and easy to carry and use.

[0030] In this embodiment, the first through hole 11 is one or more combinations of straight through holes and oblique through holes.

[0031] In practical use, the straight-shaped nozzles allow the airflow inside the cavity to blow out vertically, providing direct and concentrated airflow for quickly drying hair or enhancing the effect on specific areas. The angled nozzles, on the other hand, allow the airflow to blow out at a certain angle, increasing the coverage and versatility of the airflow direction. By combining the two, the angle and direction of the airflow can be adjusted according to different hair styling needs and the areas being styled, achieving more precise hair treatment. Different angles of airflow produce different effects when styling hair. For example, for areas requiring volume, the airflow from the angled nozzles can be blown diagonally upwards from below, making the roots more voluminous; while for areas requiring smoothness, the vertical airflow from the straight nozzles can be used for styling, making the hair smoother and more organized.

[0032] The combination of straight and angled through-holes allows airflows from different directions to converge and mix within the air gap 6, resulting in a more uniform airflow. This uniform airflow prevents localized overheating or cooling during hair drying, reducing damage and ensuring more even drying. This uniform airflow not only benefits the hair but also improves user comfort when using the hair dryer. It eliminates the feeling of inconsistent airflow, providing a more comfortable and stable user experience.

[0033] Specifically, the hair-planting frame 1 is also provided with a comb tooth blind hole 12, and a comb tooth 5 is provided in the comb tooth blind hole 12, and the comb tooth 5 protrudes out of the heat conduction component 2 through the second through hole 21.

[0034] In practical use, the comb teeth and airflow structure are combined to achieve integrated combing and blow-drying functions. During hair combing, the hot air blown by the heat conduction component 2 directly acts on the hair being combed, simultaneously completing combing, drying, and styling, saving time and steps. The comb teeth 5 extend through the second through-hole 21, allowing the hot air to be more precisely guided along the comb teeth to the hair. For example, when working the roots, the comb teeth penetrate deep into the hair roots, allowing the hot air to act directly on them, effectively drying the roots and creating a voluminous effect. The blind holes 12 of the comb teeth fix the comb teeth 5, preventing the comb teeth from shaking and damaging the hair. Simultaneously, during combing, the comb teeth can appropriately disperse the hair, allowing the hot air to act evenly on each strand, avoiding localized overheating and reducing heat damage to the hair. The design of the blind holes 12 of the comb teeth facilitates the disassembly and installation of the comb teeth 5. If the comb teeth 5 is damaged or needs cleaning, it can be easily removed for replacement or washing, extending the lifespan of the hair dryer and maintaining its good performance.

[0035] Specifically, the surface of the flocking frame 1 facing away from the cavity protrudes towards the heat conduction element 2 to form a guide strip 13. The guide strip 13 is arranged along the length of the heat conduction element 2, and the number of guide strips 13 is set to multiple. The multiple guide strips 13 are arranged around the central axis of the flocking frame 1. The multiple guide strips 13 are located in the air gap 6 and are divided into different airflow channels. The multiple guide strips 13 abut against the inner surface of the heat conduction element 2.

[0036] In actual use, the guide strips 13 can guide the hot air to flow along a specific path within the air gap 6, allowing the hot air to diffuse more orderly from the first through hole 11 to various parts, avoiding uneven heat distribution caused by turbulent hot air flow. Multiple guide strips 13 divide the air gap 6 into different airflow channels, allowing the hot air to be distributed more evenly on the surface of the heat conduction component 2, further improving the overall heating uniformity of the heat conduction component 2, reducing local temperature differences, and improving the performance of the comb head.

[0037] The guide strip 13 increases the contact area and contact time between the hot air and the inner surface of the heat transfer component 2, promoting heat exchange and thus improving the heating efficiency of the heat transfer component 2, enabling it to reach the required temperature more quickly. The guide strip 13 also constrains and stabilizes the hot air, reducing fluctuations and eddies during its flow, making the hot air blown from the second through-hole 21 more stable and enhancing the stability and consistency of the airflow from the comb head.

[0038] Specifically, the number of the first through hole 11, the comb tooth blind hole 12, and the second through hole 21 are all set to be multiple. Multiple first through holes 11 are arranged along the length direction of the hair-planting frame 1 to form a first hole group, multiple comb tooth blind holes 12 are arranged along the length direction of the hair-planting frame 1 to form a blind hole group, and multiple second through holes 21 are arranged along the length direction of the heat-conducting component 2 to form a second hole group.

[0039] In actual use, multiple first through holes 11 are arranged along the length of the hair-forming frame 1 to form a first hole group. This allows hot air inside the cavity to be evenly blown directly onto the inner surface of the heat-conducting component 2 from multiple positions, preventing hot air from concentrating in one place and making the surface of the heat-conducting component 2 heated more evenly. This improves the consistency of the heating effect of the entire hair comb and ensures that different parts of the hair receive relatively uniform hot air treatment during use. Multiple second through holes 21 are arranged along the length of the heat-conducting component 2 to form a second hole group, which facilitates the even blowing of hot air from the air gap 6 along the extension direction of the comb teeth. In this way, when combing hair, different parts of the hair can be blown with even hot air, avoiding local overheating or undercooling and improving the user experience of the hair comb.

[0040] Multiple blind holes 12 are arranged along the length of the tufting frame 1 to form a blind hole group, providing a regular layout basis for the installation of the comb teeth. This allows the comb teeth to be inserted in an orderly manner, ensuring a uniform distribution of the teeth, which not only meets the actual needs of combing the hair but also adapts to the airflow channel structure, ensuring the synergy of the comb head in combing and drying hair. The regularly arranged multiple groups of holes ensure that the tufting frame 1 and the heat conduction component 2 maintain a relatively uniform stress distribution even after the holes are made. This avoids structural weaknesses caused by too many or too few holes in a certain area, enhances the stability of the combined structure of the tufting frame 1 and the heat conduction component 2, and extends the service life of the comb head.

[0041] Specifically, the number of the first hole group, the second hole group, and the blind hole group are all set to be multiple. The multiple first hole groups and the multiple blind hole groups are arranged around the central axis of the hair-planting frame 1, and the multiple second hole groups are arranged around the central axis of the heat conduction component 2.

[0042] In actual use, multiple sets of first holes are arranged around the central axis of the hair-forming frame 1, allowing hot air inside the cavity to blow directly onto the inner surface of the heat-conducting component 2 from multiple angles, achieving more uniform heating of the heat-conducting component 2 from all directions. This ensures the temperature consistency of the heat-conducting component 2 in the circumferential direction, avoiding differences in heating effect in different parts of the comb head due to uneven local heating, and improving the overall heating efficiency. Multiple sets of second holes are arranged around the central axis of the heat-conducting component 2, allowing hot air to be evenly distributed across the entire circumference of the comb teeth when blown out from the air gap 6 along the direction of the comb teeth. When using the comb head, hair in different directions can be blown evenly, ensuring that all parts of the hair receive the same level of hot air care, improving the usage effect.

[0043] Multiple blind hole groups are arranged around the central axis of the hair grafting frame 1, providing a more comprehensive installation layout for the comb teeth. This makes the comb teeth more densely and evenly distributed on the hair grafting frame 1, better adapting to the combing needs of different hairstyles and hair volumes, and enhancing the combing function of the air-cooled comb. At the same time, this layout matches the even blowing of hot air, ensuring that every strand of hair is blown by hot air during the combing process, achieving an efficient combination of combing and drying. The arrangement of the first hole group, the second hole group, and the blind hole group around the central axis gives the air-cooled comb a good symmetry in its airflow channel structure. The symmetrical distribution of the hole groups makes the hair grafting frame 1 and the heat conduction component 2 more evenly stressed in all directions, reducing deformation or damage caused by uneven stress, further improving the overall stability and durability of the air-cooled comb structure, and extending the product's service life.

[0044] In this embodiment, the first hole group and the blind hole group are arranged at intervals.

[0045] In actual use, the spaced arrangement prevents the hot air blown out of the first through hole 11 from directly impacting the blind holes 12 of the comb teeth. This ensures that the hot air diffuses more smoothly in the air gap 6 between the flocking frame 1 and the heat conduction component 2, allowing the hot air to heat the heat conduction component 2 more evenly, optimizing the heat transfer efficiency in the airflow channel, and improving the overall heating effect of the comb head. This arrangement also rationally allocates space on the flocking frame 1 for the hot air channel and the comb tooth installation area, preventing the weakening of the local structural strength of the flocking frame 1 due to excessive concentration of holes. This ensures that the flocking frame 1 still has good structural stability when subjected to hot air pressure and comb tooth installation stress, extending the service life of the comb head.

[0046] The spaced arrangement of the holes ensures the integrity of the structure surrounding each blind hole 12 on the comb teeth, providing stable support and preventing loosening due to interference from the surrounding hot air channels during use. This guarantees the reliability and stability of the comb's hair-cleaning function, enhancing the user experience. During manufacturing, the spaced hole arrangement facilitates processing and positioning, reducing production difficulty. In later maintenance, if a problem occurs in a certain area, the spaced layout makes repair operations clearer and easier to disassemble and replace related components.

[0047] Specifically, the second through hole 21 is aligned with the comb tooth blind hole 12 and the diameter of the second through hole 21 is larger than the diameter of the comb tooth blind hole 12.

[0048] In actual use, the outer diameter of the comb teeth 5 is smaller than the diameter of the second through hole 21, creating an annular airflow channel between the comb teeth 5 and the second through hole 21. This allows the airflow within the cavity to exit through this annular airflow channel. The second through hole 21 is aligned with the blind hole 12 of the comb teeth, and the diameter of the second through hole 21 is larger than that of the blind hole 12, allowing for better guidance of the airflow as it passes through the second through hole 21. The airflow is then evenly distributed around the comb teeth 5, resulting in more even application to the hair and improved drying and styling effects.

[0049] If the outer diameter of the comb teeth 5 is equal to or too large than the diameter of the second through hole 21, hair or other debris may easily enter the hole during use and be difficult to expel, thus blocking the airflow channel. This size design provides a certain gap between the hole and the comb teeth 5, reducing the possibility of blockage and ensuring the normal use of the hair dryer. The comb teeth 5 have some room to move within the second through hole 21 because the diameter of the second through hole 21 is larger than the outer diameter of the comb teeth 5. Therefore, the comb teeth 5 can be flexible when combing hair, better adapting to different hairstyles and hair types, reducing pulling and damage to the hair.

[0050] Specifically, the tail end of the hair-planting frame 1 is provided with an end shell 3, and the air inlet end of the hair-planting frame 1 is provided with a mounting part 4 for mounting the hair-planting frame 1 on the comb head body.

[0051] In actual use, an end shell 3 is installed at the tail end of the flocking frame 1. After being snapped into place, it effectively seals the tail end of the flocking frame 1, improves the airflow channel structure of the comb head, prevents hot air leakage from the tail end, ensures that hot air flows within the designed channel, and improves thermal efficiency. The end shell 3 protects the internal hot air chamber and other related components of the flocking frame 1 from external impacts, dust, or moisture, extending the service life of internal components and ensuring stable performance of the comb head.

[0052] The mounting section 4 allows the flocking frame 1 to be easily installed on the comb head body, providing a standard interface for the connection between the flocking frame 1 and the comb head body, simplifying the installation process, reducing installation difficulty, and improving production assembly efficiency. The snap-fit ​​connection between the end shell 3 and the flocking frame 1, as well as the design of the mounting section 4, play a positioning role during installation, ensuring that the flocking frame 1 is accurately positioned on the comb head body, guaranteeing the fit accuracy between the airflow channel structure and other parts of the comb head body, thereby ensuring the normal functioning of the overall comb head.

[0053] Specifically, the end shell 3 has a locking block 31, and the tail end of the hair-planting frame 1 has a locking groove 14 that engages with the locking block 31. The number of locking blocks 31 and locking grooves 14 is set to be multiple, and the locking blocks 31 and locking grooves 14 correspond one-to-one. The multiple locking blocks 31 and multiple locking grooves 14 are arranged around the central axis of the hair-planting frame 1.

[0054] In actual use, multiple locking blocks 31 correspond one-to-one with the locking slots 14 and are arranged around the central axis of the hair-planting frame 1, so that when the end shell 3 and the hair-planting frame 1 are connected, the force can be evenly distributed on the end circumference of the hair-planting frame 1. Compared with single-point or few-point connections, this multi-point surrounding connection greatly disperses external forces. Whether in normal use or under certain external impact, it can effectively prevent the end shell 3 from separating from the hair-planting frame 1 due to excessive local force, ensuring the firmness and stability of the connection. When the comb head is used, it may be subjected to a certain torsional force, such as the slight rotation of the hand when combing hair. Multiple evenly distributed locking blocks 31 cooperate with the locking slots 14, like multiple tiny "locks", to resist this torsional force, keeping the end shell 3 and the hair-planting frame 1 tightly connected and preventing loosening due to torsion, thus ensuring the reliability of the overall structure of the comb head.

[0055] Because the locking blocks 31 correspond one-to-one with the slots 14 and are distributed around the perimeter, operators can quickly identify and align the positions of the locking blocks 31 and slots 14 when assembling the end shell 3 and the flocking frame 1. This eliminates the need to spend excessive time finding suitable connection points, greatly improving assembly accuracy and efficiency. The surrounding design also provides a degree of automatic calibration. When the end shell 3 and the flocking frame 1 begin to align, even with a slight initial positional deviation, as the locking blocks 31 gradually enter the slots 14, the end shell 3 will automatically adjust to the correct position under the combined action of multiple locking blocks 31, ensuring assembly precision and reducing structural problems caused by assembly errors.

[0056] Multiple locking blocks 31 fit tightly with the locking slots 14, effectively reducing the gap between the end shell 3 and the end of the tufting frame 1. During operation, hot air flows inside the tufting frame 1. The tight connection prevents hot air leakage from the connection between the end shell 3 and the tufting frame 1, ensuring efficient airflow within the predetermined airflow path and improving the thermal efficiency and performance of the comb. This tight connection not only prevents hot air leakage but also blocks dust, hair, and other foreign objects from entering the tufting frame 1, preventing damage to the internal structure and extending the service life of the comb.

[0057] Specifically, the end shell 3 covers the heat conduction element 2, thus limiting one end of the heat conduction element 2. The side of the hair grafting frame 1 near the mounting part 4 protrudes in the direction away from the cavity to form a limiting protrusion 15 for limiting the other end of the heat conduction element 2. The heat conduction element 2 is provided with a limiting hole 22 that cooperates with the limiting protrusion 15. The end shell 3 cooperates with the limiting protrusion 15 to limit both ends of the heat conduction element 2.

[0058] In actual use, the end shell 3 covers the heat conduction component 2 and limits one end of it. At the same time, the limiting protrusion 15 on the tufting frame 1 cooperates with the limiting hole 22 of the heat conduction component 2 to limit the other end of the heat conduction component 2. This method of limiting both ends can effectively prevent the heat conduction component 2 from shifting due to vibration, external force pulling, or other factors during the operation of the comb head, ensuring that the heat conduction component 2 always remains in the designed position, maintaining the stability of the airflow channel structure, ensuring that hot air can flow between the tufting frame 1 and the heat conduction component 2 along a predetermined path, and improving the working performance of the comb head. After the position of the heat conduction component 2 is fixed, the relative movement between it and surrounding components (such as the tufting frame 1, comb teeth, etc.) is reduced, reducing wear caused by friction between components and extending the service life of the heat conduction component 2 and the entire comb head.

[0059] During assembly, the limiting effect of the end shell 3 and the limiting protrusion 15 on the heat conduction component 2 provides clear assembly guidance for the operator. Based on the covering position of the end shell 3 and the mating relationship between the limiting protrusion 15 and the limiting hole 22, the operator can quickly and accurately install the heat conduction component 2 into the designated position, improving assembly efficiency and reducing product quality problems caused by improper assembly. This limiting design ensures the installation accuracy of the heat conduction component 2 in the comb head, making the fit between the heat conduction component 2 and components such as the tufting frame 1 and the end shell 3 more compact and accurate, contributing to the improved compactness and stability of the overall structure of the comb head.

[0060] The end shell 3 and the limiting protrusion 15 effectively restrict the position of the heat conduction component 2, preventing it from shifting and creating gaps, thus preventing hot air leakage from both ends of the heat conduction component 2. This ensures smooth airflow through the air gap 6 between the flocking frame 1 and the heat conduction component 2, as well as through the path blown out by the comb teeth, improving the utilization rate of hot air and enhancing the heating and drying effect of the comb head. After the position of the heat conduction component 2 is fixed, the flow of hot air within the air gap 6 between the flocking frame 1 and the heat conduction component 2 is more stable and uniform, which helps to optimize the distribution of hot air in the entire airflow channel, allowing the heat conduction component 2 to be heated more evenly, thereby making the temperature of the hot air blown out from the comb teeth more uniform and improving the user experience.

[0061] Specifically, the heat conduction element 2 is a thin-walled tubular structure with openings at both ends, and the heat conduction element 2 is made of aluminum or stainless steel with a thickness of 1 to 3 mm.

[0062] In actual use, multiple second through holes 21 are opened through the periphery of the heat conduction component 2. The heat conduction component 2 is preferably made of aluminum or stainless steel with good thermal conductivity, with a thickness of 1 to 3 mm. The heat conduction component 2 is sleeved on the outer periphery of the hair grafting frame 1. The inner surface of the heat conduction component 2 abuts against the guide strip 13. The multiple guide strips 13 support the inner surface of the heat conduction component 2 to ensure that the structure of the heat conduction component 2 is stable and not deformed by external force. After the heat conduction component 2 is sleeved on the outer periphery of the hair grafting frame 1, the comb tooth 5 first passes through the second through hole 21 and then is implanted into the comb tooth blind hole 12. Therefore, the diameter of the second through hole 21 is larger than the diameter of the comb tooth blind hole 12, which is more conducive to the implantation and installation of the comb tooth 5.

[0063] In this embodiment, the hair-planting frame 1 protrudes into the cavity and extends into a limiting post 16 for limiting the external structure. The limiting post 16 is arranged along the length of the hair-planting frame 1 and is stepped from the mounting part 4 to the end shell 3.

[0064] In actual use, the limiting posts 16 are arranged along the length of the flocking frame 1, providing a precise positioning reference for the external structure it mates with. Whether during assembly or use, these limiting posts 16 ensure the correct relative position between the external structure and the flocking frame 1, guaranteeing the coordinated operation of the airflow duct structure and all internal components of the comb head. Because the limiting posts 16 are stepped from the mounting section 4 to the end shell 3, this design can adapt to the limiting requirements of external structures of different sizes or shapes. For example, there may be different specifications of airflow duct components, insulation layers, and other external structures; the stepped limiting posts 16 can provide suitable positioning and support according to their specific requirements, enhancing the compatibility of the flocking frame 1 with different external structures.

[0065] The locating posts 16, arranged along the length, can evenly distribute the force on the external structure to the flocking frame 1 when fixing the external structure. This avoids excessive local stress that could cause deformation or damage to the flocking frame 1, especially during the operation of the comb head, which may be subjected to external forces such as hot air pressure and vibration. The presence of the locating posts 16 helps maintain the stability of the flocking frame 1 and the entire comb head structure. The stepped locating posts 16 can form a tighter and more stable connection with the external structure. By adapting the locating posts 16 of different heights to the external structure, the contact area and friction between the two can be increased, further improving the strength of the connection and reducing noise or problems affecting the performance of the comb head caused by loose parts.

[0066] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
