Description

Technical Field

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

[0002] In the personal care and hair styling industry, hair straighteners, as tools that combine combing and heated styling functions, have become a common daily hair styling device for many consumers due to their ease of use and instant styling effects. Currently, mainstream hair straighteners on the market typically consist of an aluminum comb body for conducting heat to straighten and shape the hair, and a handle assembly for holding and controlling the tool. Among these, the aluminum comb body, as the key component that directly contacts the hair and enables the heated styling function, has a structural design that directly affects the user experience and functional expandability of the product.

[0003] The existing aluminum comb body of straightening combs has obvious functional limitations in its structural design. Specifically, the aluminum comb body only has a comb tooth structure integrally formed on the front side facing the hair styling operation direction. This comb tooth structure usually adopts a uniformly arranged sharp tooth shape, which is used to comb the hair and assist in heat transfer during the heating process to achieve a straightening and smooth styling effect. However, the back side of the aluminum comb body (i.e. the non-operational side opposite to the front side) is completely covered by a plastic comb tooth sleeve. This plastic comb tooth sleeve only serves as heat insulation and protection, and does not have a comb tooth structure itself, nor can it conduct heat.

[0004] The aforementioned structural design leads to the following problems with existing hair straighteners in practical use: First, limited functionality and restricted usage scenarios. Since only the front of the aluminum comb body has heated bristles, users can only rely on this single working surface when styling hair. They cannot flexibly switch the working surface of the aluminum comb body according to different styling needs (such as fine shaping of local hair strands, combing at different angles, etc.), reducing the product's styling flexibility. Second, cumbersome operation and low efficiency. When styling different areas of the hair, users need to constantly adjust their hand grip to ensure the front of the aluminum comb body always faces the hair to be styled. This is especially problematic when dealing with long hair or complex styles, easily exacerbating hand fatigue and affecting styling efficiency. Third, low utilization of the base material and wasted function. Although the back of the aluminum comb body has the same metal heat-conducting base material as the front, it is completely encased in plastic bristle sleeves, preventing it from performing its heating and styling function. This results in low utilization of the metal base material and fails to fully exploit the product's functional potential.

[0005] As consumers increasingly demand more multifunctional and convenient hair styling tools, the existing aluminum comb body structure of straight hair combs with only one side of comb teeth and limited functionality can no longer meet the market's demand for efficient and flexible hair styling equipment. Therefore, it is urgent to optimize the design of the aluminum comb body structure of straight hair combs to break through the limitations of existing technology and improve the user experience and functional value of the product. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a comb structure and hair styling tool.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: In a first aspect, this utility model provides a comb structure, including: a metal body and a comb tooth sleeve. The front of the metal body extends upward with long comb teeth, and the back extends downward with short comb teeth. The comb tooth sleeve is connected to the metal body. The comb tooth sleeve is provided with an anti-scalding part on the outside of the long comb teeth, and is provided with isolation teeth on both sides of the short comb teeth.

[0008] In one specific embodiment, the width of the long comb teeth gradually narrows upwards from the metal body, forming a cone shape.

[0009] In one specific embodiment, the height of the long comb teeth is 24mm-30mm.

[0010] In one specific embodiment, the front side of the metal body extends upward with a plurality of the long comb teeth, and the gap between adjacent long comb teeth is 0.8mm-1.5mm.

[0011] In one specific embodiment, the metal body at the bottom of the long comb teeth is arc-shaped.

[0012] In one specific embodiment, the short comb teeth are arc-shaped.

[0013] In one specific embodiment, the height of the short comb teeth is 1.2mm-2mm.

[0014] In one specific embodiment, a plurality of short comb teeth extend downward from the back side of the metal body, and the gap between adjacent short comb teeth is 0.8mm-1.5mm.

[0015] In one specific embodiment, the height of the isolation tooth is 10mm-15mm.

[0016] Compared with existing technologies, the advantages of this comb structure are as follows: By using a bidirectional comb tooth layout with long comb teeth extending upwards on the front and short comb teeth extending downwards on the back of the metal body, both sides of the metal body have comb tooth structures that can directly participate in styling. The long comb teeth on the front can continue the efficient combing and straightening styling function of traditional straighteners for long and coarse hair, and are suitable for smoothing large areas of hair. The short comb teeth on the back can be used for fine shaping of local areas such as the ends of short hair and bangs, or for hair strands that need to be slightly fluffy. This avoids the problem of having to frequently adjust the grip posture to handle different areas of hair in traditional structures. Users can flexibly choose to use the front or back of the metal body according to their styling needs (such as overall straightening, local modification, and angle adjustment), which greatly improves the styling flexibility and applicable scenario coverage of the comb and solves the core pain point of the single function of existing products. Furthermore, on the one hand, the comb teeth are equipped with anti-scalding parts on the outside of the long comb teeth, which can physically isolate the high-temperature area around the long comb teeth on the front of the metal body, preventing users from directly contacting the high-temperature metal parts and getting burned when holding or adjusting the operating angle; on the other hand, isolation teeth are set on both sides of the short comb teeth, which can not only provide lateral protection for the short comb teeth on the reverse side, preventing hair from getting too tangled at the base of the comb teeth when styling in the opposite direction, but also help the short comb teeth to limit the combing of hair, improving the stability of reverse styling. This design can achieve a two-way styling function, while effectively avoiding the safety hazards that two-way comb teeth may bring through the targeted protection of the anti-scalding parts and isolation teeth, thus achieving a balance between "functional expansion" and "safety protection".

[0017] Secondly, this utility model embodiment provides a hair styling tool, including the comb structure described above.

[0018] Compared with existing technologies, the beneficial effects of this hair styling tool are as follows: By setting up a comb body structure and adopting a two-way comb tooth layout with long comb teeth extending upwards on the front and short comb teeth extending downwards on the back, both sides of the metal body have comb tooth structures that can directly participate in styling. The long comb teeth on the front can continue the efficient combing and straightening styling function of traditional straighteners for long and coarse hair, and are suitable for smoothing large areas of hair. The short comb teeth on the back can be used for fine shaping of local areas such as the ends of short hair and bangs, or for hair strands that need to be slightly fluffy. This avoids the problem of having to frequently adjust the grip posture to deal with different areas of hair in traditional structures. Users can flexibly choose to use the front or back of the metal body according to their styling needs (such as overall straightening, local modification, angle adjustment), which greatly improves the styling flexibility and applicable scenario coverage of the comb body and solves the core pain point of the single function of existing products. Furthermore, on the one hand, the comb teeth are equipped with anti-scalding parts on the outside of the long comb teeth, which can physically isolate the high-temperature area around the long comb teeth on the front of the metal body, preventing users from directly contacting the high-temperature metal parts and getting burned when holding or adjusting the operating angle; on the other hand, isolation teeth are set on both sides of the short comb teeth, which can not only provide lateral protection for the short comb teeth on the reverse side, preventing hair from getting too tangled at the base of the comb teeth when styling in the opposite direction, but also help the short comb teeth to limit the combing of hair, improving the stability of reverse styling. This design can achieve a two-way styling function, while effectively avoiding the safety hazards that two-way comb teeth may bring through the targeted protection of the anti-scalding parts and isolation teeth, thus achieving a balance between "functional expansion" and "safety protection".

[0029] See Figures 1 to 4 As shown, this utility model discloses a specific embodiment of a comb body structure, including: a metal body 10 and a comb tooth sleeve 20. The metal body 10 has long comb teeth 11 extending upward from the front and short comb teeth 12 extending downward from the back. The comb tooth sleeve 20 is connected to the metal body 10. The comb tooth sleeve 20 has an anti-scalding part 21 on the outside of the long comb teeth 11 and isolation teeth 22 on both sides of the short comb teeth 12.

[0030] Specifically, the metal body 10 is preferably made of aluminum alloy, which has excellent thermal conductivity and structural strength. The metal body 10 has a pre-set mounting groove that is compatible with the heating component (such as a PTC heating element). After the heating component is embedded, the temperature can be transferred to the front and back comb teeth through the metal body 10 to realize the heating and shaping function.

[0031] The long comb teeth 11 on the front are made by one-piece extrusion molding process, extending upward from the front of the metal body 10 (defined as the working surface that first contacts a large area of ​​hair when styling), and the tips of the teeth are rounded. The long comb teeth 11 are evenly arranged along the length of the metal body 10 to ensure that long and thick hair can be stably clamped and guided when combing, while avoiding pulling the hair strands.

[0032] The short comb teeth 12 on the reverse side are also integrally extruded and extend downward from the reverse side of the metal body 10. The short comb teeth 12 are evenly arranged in a single or double row along the length of the metal body 10 and are staggered from the projected position of the long comb teeth 11 on the front side to avoid the structural strength of the metal body 10 being reduced due to the dense comb teeth.

[0033] The comb tooth cover 20 is made of high-temperature resistant plastic material (such as PP + glass fiber composite material), and is fixed to the edge of the metal body 10 (i.e. both sides of the length direction and one end of the width direction of the metal body 10) by snap-fit ​​connection or ultrasonic welding, forming a "semi-enclosed" structure of the metal body 10 - only covering the edge area of ​​the metal body 10, without blocking the comb teeth on the front and back, ensuring that the comb teeth can contact the hair normally.

[0034] The anti-scalding part 21 is a protruding structure that extends from the comb sleeve 20 to the outside of the long comb teeth 11 on the front. The inner side of the anti-scalding part 21 is in contact with the front edge of the metal body 10, and the outer side is a smooth arc surface. Insulation cotton (such as ceramic fiber cotton) can be added inside to further reduce the heat conduction efficiency of the anti-scalding part 21 and avoid the surface temperature from being too high.

[0035] The isolation tooth 22 is a columnar protrusion extending from the comb sleeve 20 to both sides of the short comb teeth 12 on the reverse side. It is arranged alternately with the short comb teeth 12 along the length of the metal body 10 - that is, one isolation tooth 22 is set between every 2-3 short comb teeth 12. The isolation tooth 22 is integrally formed with the comb sleeve 20 and the surface is smoothed to avoid snagging hair strands.

[0036] In other words, by using a two-way comb tooth layout with long comb teeth 11 extending upwards on the front and short comb teeth 12 extending downwards on the back of the metal body 10, both sides of the metal body 10 have comb tooth structures that can directly participate in styling. The long comb teeth 11 on the front can continue the efficient combing and straightening styling function of traditional straighteners for long and coarse hair, and are suitable for smoothing large areas of hair. The short comb teeth 12 on the back can be used for fine shaping of local areas such as the ends of short hair and bangs, or for hair strands that need to be slightly fluffy. This avoids the problem of having to frequently adjust the grip to handle different areas of hair in traditional structures. Users can flexibly choose to use the front or back of the metal body 10 according to their styling needs (such as overall straightening, local modification, and angle adjustment), which greatly improves the styling flexibility and applicable scenario coverage of the comb and solves the core pain point of the single function of existing products. Furthermore, on the one hand, the comb tooth cover 20 has an anti-scalding part 21 on the outside of the long comb teeth 11, which can physically isolate the high-temperature area around the long comb teeth 11 on the front of the metal body 10, preventing the user from being burned by direct contact with the high-temperature metal parts when holding or adjusting the operating angle; on the other hand, isolation teeth 22 are set on both sides of the short comb teeth 12, which can not only provide lateral protection for the short comb teeth 12 on the reverse side, preventing the hair from getting too tangled at the root of the comb teeth when styling in the opposite direction, but also help the short comb teeth 12 to limit the combing of the hair, improving the stability of the reverse styling. This design can achieve the dual-directional styling function, and through the targeted protection of the anti-scalding part 21 and the isolation teeth 22, it can effectively avoid the safety hazards that dual-directional comb teeth may bring, achieving a balance between "functional expansion" and "safety protection".

[0037] In one embodiment, the width of the long comb teeth 11 gradually narrows from the metal body 10 upwards, forming a cone shape.

[0038] Specifically, in existing technologies, the long comb teeth 11 are mostly of equal width. During combing, hair tends to become clogged between the teeth, especially for tangled or frizzy hair. The resistance from equal-width teeth is greater, which can easily lead to hair breakage or scalp pain. The tapered long comb teeth 11 of this embodiment have a narrower tip that can more easily insert into the gaps between tangled hair strands, gradually separating the tangled strands like a "probe." The wider base can stably hold the hair during subsequent combing, guiding it to move smoothly along the length of the comb teeth. This achieves the combing logic of "first guiding, then holding," significantly reducing combing resistance, minimizing hair pulling damage, and improving user comfort. In addition, as the terminal for heat transfer from the metal body 10, the structural shape of the long comb teeth 11 affects heat distribution. In the conical design, the wider root increases the contact area with the metal body 10, ensuring that heat is quickly transferred to the comb teeth. The gradual change in width from the root to the tip creates a gradient distribution of heat capacity in different parts of the comb teeth. Although the tip is narrow, the heat density is relatively higher because the contact point with the hair is more concentrated, allowing it to act quickly on the hair. The wider root results in a wider heat radiation range, which can also preheat the surrounding hair. This heat distribution characteristic allows the long comb teeth 11 to precisely heat and shape local hair through the tip, and to evenly heat a large area of ​​hair through the root, improving the uniformity of the overall styling and avoiding poor styling results caused by local overheating or underheating.

[0039] In one embodiment, the height of the long comb teeth 11 is 24mm-30mm.

[0040] Specifically, the 24mm-30mm long comb teeth 11 can penetrate deep into the hair shaft, wrapping more layers of hair at once. Especially when straightening, the long comb teeth 11 can hold the hair from root to tip, ensuring that each strand fully contacts the heated area, achieving a "smooth in one combing" effect. At the same time, the longer comb teeth can better guide the direction of the hair, reducing hair deviation during styling, significantly improving the drape and neatness of the final hairstyle, and making the hair styling effect last longer. In addition, the 24mm-30mm long comb teeth 11 is not only suitable for basic straight hair styling, but can also meet more diverse hairstyle needs. For example, when creating big wavy curls, the longer comb teeth can easily wrap more hair, and with the comb's heating function, achieve a natural curl. When dealing with voluminous hairstyles, the long comb teeth 11 can penetrate deep into the root area, creating a long-lasting root volume effect through a combination of heating and combing, avoiding the limitations of traditional short comb teeth 12 which can only work on the mid-lengths and ends of the hair.

[0041] In one embodiment, the metal body 10 has a plurality of long comb teeth 11 extending upward on its front side, and the gap between adjacent long comb teeth 11 is 0.8mm-1.5mm.

[0042] Specifically, based on the conical shape of the long comb teeth 11, the gap between adjacent long comb teeth 11 is set with the root as the reference and remains uniform along the height direction of the comb teeth. For long comb teeth 11 with a root width of 1.5-2mm, the gap between adjacent comb teeth at the root is set to 0.8mm-1.5mm, of which 0.8-1.1mm gap is used for models with fine and soft hair and the need for fine styling, and 1.2-1.5mm gap is used for models with coarse and hard hair and the need for quick styling.

[0043] In other words, the smaller gaps of 0.8mm-1.5mm allow for a tight grip on single or small strands of hair, especially when working on delicate areas like bangs and partings. This precise guidance helps guide the hair, preventing it from becoming tangled. Simultaneously, the denser gaps between the comb teeth gather frizzy stray hairs into the main hair strands, resulting in a neater, smoother final hairstyle and enhancing the style's sophistication and dimension. Furthermore, the smaller gaps between the long comb teeth mean that adjacent teeth are closer together, allowing the heat radiation from the heated teeth to overlap, creating a more even heating area. When hair passes through the gaps, each strand makes full contact with the teeth and receives uniform heat, avoiding the problem of some strands being underheated due to distance from the teeth in traditional wide-gap combs. For coarse hair, the smaller gaps increase the contact points between the hair and the teeth, shortening the heating and shaping time while ensuring even heating of the inner and outer layers of the hair. This reduces uneven heating that can lead to inconsistent volume and short-lasting straightening effects.

[0044] In one embodiment, the metal body 10 is arc-shaped at the bottom of the long comb teeth 11.

[0045] Specifically, the area of ​​the metal body 10 at the bottom of the long comb teeth 11 (i.e., the connection between the long comb teeth 11 and the metal body 10) is designed as an arc transition. The arc extends to cover both sides and the bottom of the root of the long comb teeth 11, and seamlessly connects with the conical surface of the long comb teeth 11 without obvious sharp edges.

[0046] In other words, the rounded bottom guides the hair strands naturally from the surface of the metal body 10 into the gaps between the comb teeth through a smooth curvature transition, reducing the contact resistance between the hair strands and the bottom of the comb teeth. Users do not need to apply excessive force during combing to achieve smooth movement of the comb, especially when dealing with long and thick hair, avoiding hand fatigue caused by jamming and improving the overall user experience. Furthermore, the rounded bottom allows the hair strands to be pre-guided before entering the gaps between the comb teeth, ensuring that the hair strands conform to the surface of the long comb teeth 11 in a more regular posture, reducing twisting and crossing of the hair strands between the comb teeth. During the heated straightening process, the regular arrangement of the hair strands allows each strand to evenly contact the heating area of ​​the comb teeth, avoiding uneven heating caused by hair twisting; at the same time, the smooth rounded transition reduces frictional damage to the hair cuticles, resulting in smoother and shinier hair after combing.

[0047] In one embodiment, the short comb teeth 12 are arc-shaped.

[0048] Specifically, the short comb teeth 12 are in the shape of "circular arc curvature". Several circular arc-shaped short comb teeth 12 are evenly arranged in a single or double row along the length direction of the lower surface of the metal body 10, and the curvature of all short comb teeth 12 is consistent, forming a continuous circular arc comb tooth array.

[0049] In other words, the curved short comb teeth 12 can directly conform to the curved direction of the hair strands. For example, when creating an inward curl at the ends of the hair, the curved comb teeth can naturally guide the ends of the hair to bend inward, and the curved shape can be easily completed without deliberately flipping the comb body. When styling bangs, the curved comb teeth can create natural curved bangs as needed, avoiding the stiff bangs style caused by straight comb teeth, and improving the convenience and naturalness of local styling.

[0050] In one embodiment, the height of the short comb teeth 12 is 1.2mm-2mm.

[0051] Specifically, based on the needs of different styling scenarios, the height of the short comb teeth 12 is set in stages from 1.2mm to 2mm; among them, a height of 1.2mm to 1.5mm is used for ultra-detailed areas such as voluminous roots and sideburn shaping; and a height of 1.6mm to 2mm is used for regular areas such as slightly curled ends and styling bangs. The height of the short comb teeth 12 on the same comb body is consistent to ensure even force during combing.

[0052] In other words, the lower height of the short comb 12 means a shorter clamping length on the hair, reducing excessive pulling and binding during styling. It is especially suitable for creating light styles such as slightly curled ends and naturally curved bangs. For example, when styling short hair ends, the 1.2mm-2mm short comb 12 only heats and shapes the 1-2mm area at the ends, creating a natural "airy" curl, avoiding the problem of overly stiff and unnatural curls caused by combs that are too high. At the same time, the shorter clamping length allows the hair to retain a certain degree of movement after styling, making the overall hairstyle more dynamic.

[0053] In one embodiment, the back surface of the metal body 10 extends downward with a plurality of short comb teeth 12, and the gap between adjacent short comb teeth 12 is 0.8mm-1.5mm.

[0054] Specifically, based on the height of the short comb teeth 12 (1.2mm-2mm), the gap between adjacent short comb teeth 12 is set to 0.8mm-1.5mm according to the "height-gap matching ratio". Among them, the short comb teeth 12 with a height of 1.2mm-1.5mm correspond to a gap of 0.8mm-1.1mm, and the short comb teeth 12 with a height of 1.6mm-2mm correspond to a gap of 1.2mm-1.5mm. This ensures that the gap and height are in a reasonable proportion, avoiding both insufficient clamping force due to excessively large gaps and hair jamming due to excessively small gaps.

[0055] In other words, the small gap of 0.8mm-1.5mm can tightly clamp single or a small number of fine hairs. Especially when dealing with bangs and sideburns, it can accurately gather messy hairs and create a neat and tidy style. In the process of fluffing the roots, the small gap comb teeth can specifically clamp the hair in the root area and achieve local fluffing by heating and shaping, avoiding the problem of the fluffing area being too large and causing the hairstyle to be messy, thus enhancing the overall sophistication of the style.

[0056] In one embodiment, the height of the isolation tooth 22 is 10mm-15mm.

[0057] Specifically, the isolation teeth 22 are 10mm-15mm high, forming a "protective barrier" on the back of the metal body 10. When the user holds the comb for reverse styling, a safe distance of more than 10mm is maintained between the hand or scalp and the high-temperature metal body 10, preventing accidental burns. The higher edges of the isolation teeth 22 also shield the sides of the metal body 10 from heat radiation, especially when handling long hair, preventing hair from pulling the hand close to the high-temperature area, thus improving safety in all aspects. In addition, the 10mm-15mm height allows the isolation teeth 22 to penetrate deep into the hair strands, achieving an auxiliary combing effect in conjunction with the cylindrical structure. When styling in reverse, the isolation teeth 22 can contact the hair strands before the short comb teeth 12, initially straightening knotted or tangled hair, laying the foundation for the fine shaping of the short comb teeth 12. At the same time, the height and spacing design of the isolation teeth 22 allows them to comb the mid-length area of ​​medium-length hair, avoiding the overall messiness caused by the short comb teeth 12 only working on a local area, reducing the need for pre-treatment with a separate comb, and improving the overall efficiency of reverse styling.

[0058] This utility model also discloses a hair styling tool, including the comb structure described above.

[0059] Specifically, by setting up a comb body structure and adopting a two-way comb tooth layout with long comb teeth 11 extending upwards on the front and short comb teeth 12 extending downwards on the back, both sides of the metal body 10 have comb tooth structures that can directly participate in styling. The long comb teeth 11 on the front can continue the efficient combing and straightening styling function of traditional straighteners for long and coarse hair, and are suitable for smoothing large areas of hair. The short comb teeth 12 on the back can be used for fine shaping of local areas such as the ends of short hair and bangs, or hair strands that need to be slightly fluffy. This avoids the problem of having to frequently adjust the grip posture to deal with different areas of hair in traditional structures. Users can flexibly choose to use the front or back of the metal body 10 according to their styling needs (such as overall straightening, local modification, and angle adjustment), which greatly improves the styling flexibility and applicable scenario coverage of the comb body and solves the core pain point of the single function of existing products. Furthermore, on the one hand, the comb tooth cover 20 has an anti-scalding part 21 on the outside of the long comb teeth 11, which can physically isolate the high-temperature area around the long comb teeth 11 on the front of the metal body 10, preventing the user from being burned by direct contact with the high-temperature metal parts when holding or adjusting the operating angle; on the other hand, isolation teeth 22 are set on both sides of the short comb teeth 12, which can not only provide lateral protection for the short comb teeth 12 on the reverse side, preventing the hair from getting too tangled at the root of the comb teeth when styling in the opposite direction, but also help the short comb teeth 12 to limit the combing of the hair, improving the stability of the reverse styling. This design can achieve the dual-directional styling function, and through the targeted protection of the anti-scalding part 21 and the isolation teeth 22, it can effectively avoid the safety hazards that dual-directional comb teeth may bring, achieving a balance between "functional expansion" and "safety protection".

[0060] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
