Description

Technical Field

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

[0002] Chinese patent CN205963265U discloses a hair straightening comb structure, which uses a single aluminum plate die-casting to form the comb teeth. The aluminum plate is heated electrically to straighten the hair. Due to manufacturing process requirements, the gaps between the comb teeth are relatively large. When styling, the large gaps between the comb teeth and the hair result in weak gripping force, leading to low straightening efficiency and poor styling results. However, this type of comb tooth makes it easy to enter the hair, so the product can also be used for curling while straightening.

[0003] Existing electric hair straighteners also employ a structure with alternating upper and lower comb teeth, using a heating device to heat the comb teeth and straighten the hair. For example, Chinese patent CN104856417B discloses an electric hair straightener with upper and lower comb teeth that fit together through through holes, and baffles at both ends of the comb teeth to prevent burns.

[0004] However, this structure has the following shortcomings: 1) The comb teeth have a simple arrangement, limiting their gripping power and the time it takes to straighten hair; 2) If it is necessary to achieve better hair grip, the comb teeth need to be made very large, which makes the product very heavy. In addition, it is not very convenient to use the comb teeth for curling hair. Utility Model Content

[0005] In view of this, the present invention provides a comb tooth structure and a straightening comb to solve the problem that the poor hair-gripping power of existing straightening combs leads to poor styling results for users.

[0006] To achieve one, some, or all of the above objectives, or other objectives, this utility model proposes a comb tooth structure, comprising: A first comb module having multiple rows of first toothed racks and a second comb module having multiple rows of second toothed racks; in any row of first toothed racks of the first comb module, there is a through hole between adjacent first toothed racks; The second comb module can pass its second tooth through the through hole and assemble it with the first comb module to form a comb section; In any row of racks in the comb section, the gap between adjacent first and second racks is a curved gap.

[0007] Furthermore, the comb structure also includes a heat insulation sleeve module, which has tooth sleeves corresponding to the position and number of the first toothed rack of the first comb module. After the comb part is assembled with the heat insulation sleeve module, the height of the tooth sleeves is higher than that of the second toothed rack.

[0008] Furthermore, the feature is that a ring of heat-insulating comb teeth is provided around the heat-insulating sleeve module.

[0009] Furthermore, the toothed sleeve is provided with a rib, the first toothed rack is provided with a groove, and when the comb tooth part is assembled with the heat insulation sleeve module, the rib and the groove are engaged accordingly.

[0010] Furthermore, the cross-section of the first rack cut by a plane perpendicular to its length direction is thick in the middle and thin at the edges; the cross-section of the first rack cut by a plane perpendicular to its length direction is thin in the middle and thick at the edges.

[0011] Furthermore, the cross-sectional shape of the first rack cut by a plane perpendicular to its length direction is an outwardly convex arc; the cross-sectional shape of the first rack cut by a plane perpendicular to its length direction is an inwardly concave arc.

[0012] Furthermore, both the first and second racks are arranged in three rows, and in the arrangement structure formed by the first and second racks in the comb section, the first and second racks are arranged in a cross pattern.

[0013] Furthermore, the gap between two adjacent first and second racks is 0.1 to 1.0 mm.

[0014] Furthermore, the gap gradually increases from the root of the tooth to the tip of the tooth.

[0015] To achieve one or more of the above objectives or other objectives, this utility model also proposes a hair straightening comb, which includes a comb handle and a comb back. The comb back is provided with the comb teeth structure described in any of the above-mentioned claims. The comb back is also provided with a heating module and a steam generating module. The comb handle is provided with a water tank and a water pump. The comb structure has a steam port on the outside of the comb teeth facing the comb teeth. The water tank, water pump and steam generating module are connected through water pipes. The steam outlet of the steam generating module is connected to the steam port. The comb teeth and the heating module abut against each other.

[0016] Implementing the embodiments of this utility model will have the following beneficial effects: After adopting the above-mentioned comb tooth structure, since the present invention uses a multi-row design for the comb teeth, and in any row of teeth, the gap between the adjacent first and second teeth is a curved gap, for example, the first tooth is a convex arc and the second tooth is a concave arc. Such curved gap structures work together to increase the contact area between the hair and the comb teeth and the straightening time, increase the straightening channel length and improve the straightening effect.

[0021] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0023] Reference Figures 1 to 13 An embodiment of this utility model provides a comb tooth structure, comprising: a comb tooth structure comprising: A first comb module 1 having multiple rows of first racks 111 and a second comb module 12 having multiple rows of second racks 121; in any row of first racks 111 of the first comb module 1, there is a through hole between adjacent first racks 111; The second comb module 12 can pass its second tooth 121 through the through hole and assemble it with the first comb module 1 to form a comb part 1; In any row of racks of the comb section 1, the gap between adjacent first rack 111 and second rack 121 is a curved gap 3.

[0024] In this embodiment, the first comb module 1 and the second comb module 12 can be formed by setting a toothed rack on the base plate, and the specific structure is as follows: Figure 1As shown, both the first comb module 1 and the second comb module 12 are good conductors of heat, and the materials can be stainless steel, aluminum, copper, aluminum alloy, titanium alloy, other alloys, ceramics, or composite materials with good thermal conductivity. The number of rows in the multiple rows of first racks 111 and multiple rows of second racks 121 can be two, three, or four, etc. By providing a through hole between the first racks 111 of the first comb module 1, and then sequentially inserting the second racks 121 of the second comb module 12 into the through hole, the first comb module 1 and the second comb module 12 are assembled to form the comb section 1, as shown. Figure 3 and Figure 4 As shown. In any row of racks in the comb section 1 described above, the gap between adjacent first racks 111 and second racks 121 is a curved surface gap 3. First, it should be emphasized that, referring to Figure 5 In this diagram, "column" refers to the vertical direction, while "row" refers to the horizontal direction. "Curved surface gap 3" refers to the arc-shaped gap between adjacent first racks 111 and second racks 121 in any row of racks. More specifically, using... Figures 3 to 8 For example, the first toothed bar 111 has convex arcs on both sides, and the second toothed bar 121 has concave arcs on both sides. The combination of these curved gaps 3 structures can increase the contact area between the hair and the comb teeth and the straightening time, increase the length of the straightening channel and improve the straightening effect.

[0025] In some embodiments, the comb structure further includes a heat insulation sleeve module 4, which has tooth sleeves 41 corresponding to the position and number of the first toothed rack 111 of the first comb module 1. After the comb part 1 is assembled with the heat insulation sleeve module 4, the height of the tooth sleeves 41 is higher than that of the second toothed rack 121.

[0026] In this embodiment, the heat insulation sleeve module 4 can be made of a material with a heat resistance of 200~300℃ or higher, preferably silicone, such as silicone with a heat resistance of 250℃. Specifically, the positions of the toothed sleeves 41 corresponding to the second toothed rack 121 are all through holes. After the heat insulation sleeve module 4 is installed, the toothed sleeves 41 wrap around the first toothed rack 111, and the height of the toothed sleeves 41 is higher than that of the second toothed rack 121. With this structure, because the spacing between the teeth is very small, if a person accidentally touches a toothed rack, they will only touch the toothed sleeves 41. Furthermore, if a straightener comb is accidentally dropped, the outer toothed sleeves 41 will protect the user from easy burns. Therefore, setting the height of the assembled toothed sleeves 41 to be higher than that of the second toothed rack 121 can achieve a good anti-scalding effect.

[0027] In some embodiments, a ring of heat-insulating comb teeth 42 is also provided around the heat insulation sleeve module 4.

[0028] In this embodiment, refer to Figure 2 and Figure 4The height of the assembled tooth sleeve 41 is set higher than that of the second toothed bar 121, mainly creating a heat insulation effect from the top of the comb teeth. Combined with the heat-insulating comb teeth 42 surrounding the heat-insulating sleeve module 4, a complete circumferential heat insulation protection is formed. If a user accidentally touches the comb teeth from the side, they will first touch the heat-insulating comb teeth 42, avoiding burns. Furthermore, it is worth mentioning that the density of the heat-insulating comb teeth 42 can be set to be greater than the density of the comb teeth in the comb tooth section 1. This facilitates the separation of the user's hair and better traps the hair between the first toothed bar 111 and the second toothed bar 121.

[0029] In some embodiments, the toothed sleeve 41 is provided with a protruding rib 411, and the first toothed rack 111 is provided with a groove 1111. When the comb tooth 1 is assembled with the heat insulation sleeve module 4, the protruding rib 411 and the groove 1111 are engaged accordingly.

[0030] In this embodiment, refer to Figure 2 The aforementioned toothed sleeve 41 has a U-shaped structure with a protruding rib 411, while the first toothed rack 111 has a groove 1111 structure. This structure is simple to assemble and fits tightly.

[0031] In some embodiments, the cross-section of the first rack 111 cut by a plane perpendicular to its length direction is thick in the middle and thin at the edges; the cross-section of the first rack 111 cut by a plane perpendicular to its length direction is thin in the middle and thick at the edges.

[0032] In this embodiment, refer to Figures 3 to 8 The cross-section of the first toothed rack 111 is similar to that of a convex lens, and the cross-section of the second toothed rack 121 is similar to that of a concave lens. After assembly, the gap between adjacent first toothed racks 111 and second toothed racks 121 is arc-shaped. This curved gap structure works together to increase the contact area between the hair and the comb teeth and the straightening time, thereby increasing the length of the straightening channel and improving the straightening effect.

[0033] In some embodiments, the cross-sectional shape of the first rack 111 cut by a plane perpendicular to its length direction is an outwardly convex arc shape; the cross-sectional shape of the first rack 111 cut by a plane perpendicular to its length direction is an inwardly concave arc shape.

[0034] In this embodiment, refer again Figures 3 to 8 The first rack 111 has a convex arc-shaped cross-section when cut by a plane perpendicular to its length direction. This means that the cross-sectional shape is... Figure 8 The shape is an outwardly convex arc in both the vertical and horizontal directions. The cross-sectional shape of the first rack 111, when cut by a plane perpendicular to its length direction, is an inwardly concave arc, meaning that this cross-sectional shape is... Figure 8Both the top and bottom directions are concave arcs. This curved surface with three gaps works together to increase the contact area between the hair and the comb teeth, increase the straightening time, increase the straightening channel length, and improve the straightening effect.

[0035] In some embodiments, the first rack 111 and the second rack 121 are both in three rows, and in the arrangement structure formed by the comb portion 1, the first rack 111 and the second rack 121 are arranged crosswise.

[0036] In this embodiment, refer to Figure 8 The first toothed bar 111 and the second toothed bar 121 are both arranged in a cross configuration. This structure allows the hair to be clamped in an "S" shape or a wavy shape. The "S" shape or wavy shape increases the contact area between the hair and the comb teeth and the straightening time, increasing the length of the straightening channel and improving the straightening effect. The first toothed bar 111 and the second toothed bar 121 are both arranged in a cross configuration, so as to... Figure 8 For example, the racks adjacent to the first rack 111 in all directions are the second rack 121, and the racks adjacent to the second rack 121 in all directions are the first rack 111.

[0037] In some embodiments, the gap between two adjacent first racks 111 and second racks 121 is 0.1 to 1.0 mm.

[0038] In some embodiments, the gap gradually increases from the root of the tooth to the tip of the tooth.

[0039] In the above embodiment, the gap between two adjacent first toothed modules 111 and 121 is set to 0.1–1.0 mm, which is reasonable for clamping hair strands. If the gap is too large, it is not conducive to straightening hair and the straightening effect is poor. If the gap is too small, the straightening efficiency is low and hair is prone to breakage. It is worth mentioning that the first comb module 1 and the second comb module 12 of this utility model form a gap of 0.1–1.0 mm through plug-in cooperation, which solves the problem of not being able to demold when such a small gap is formed by one-piece molding. In addition, the gap is arranged to gradually increase from the root of the tooth to the top of the tooth, which is conducive to grasping hair strands and improving straightening efficiency.

[0040] Reference Figures 9 to 13 The present invention also proposes a hair straightening comb, which includes a comb handle 5 and a comb back 6. The comb back 6 is provided with the comb tooth structure described in any of the above claims. The comb back 6 is also provided with a heating module 61 and a steam generating module 62 inside. The comb handle 5 is provided with a water tank 51 and a water pump 52. The comb structure has a steam port 7 with a nozzle facing the comb section 1 on the outside of the comb section 1. The water tank 51, water pump 52 and steam generating module 62 are connected through water pipes. The steam outlet of the steam generating module 62 is connected to the steam port 7. The comb section 1 and the heating module 61 abut against each other.

[0041] In this embodiment, the water tank 51 and water pump 52 can be installed on the comb handle 5, and the steam generating module 62 can be installed on the comb back 6. Figure 12 and Figure 13 For example, the water tank 51 can be located at the handle 5. Since the water tank 51 is relatively heavy after being filled with water, its location at the handle shifts the center of gravity of the comb structure towards the rear, making it easier for the user to hold and operate. Preferably, the water tank 51 can be a detachable water tank 51, with a shape adapted to the handle profile for easy water filling. It is worth mentioning that the steam generating module 62 can be configured to deliver steam to the steam zone at a flow rate of 0.05 ml / min to 6 ml / min.

[0042] Specifically, the main housing 621 of the steam generating module 62 is a four-chamber box-shaped structure. This box-shaped structure is made of a heat-conducting material, such as metal, and more specifically, stainless steel, aluminum, copper, aluminum alloy, titanium alloy, or other alloys. More specifically, the main housing 621 has a double-layer structure, with an upper layer of three parallel chambers and a lower layer of one chamber. The heat source of the steam generating module 62 is located in the lower chamber, and the heat source is a heating wire or heating element. Preferably, the box-shaped structure is flat and elongated, with a longer flow channel for a longer vaporization time, which is beneficial for fully vaporizing water and for more precise control of the steam temperature. The middle chamber of the upper layer connects to the chambers on both sides, and these chambers on both sides correspond to the steam ports 7 on the left and right sides of the comb-tooth section 1, respectively. Figure 10 As shown, it should be noted that the steam nozzle 7 is oriented towards the comb teeth. For example, the angle between the axis of the nozzle and the length of the comb teeth is 15-75 degrees, preferably 30-60 degrees, such as 45 degrees.

[0043] When in use, the water pump 52 draws water to the upper middle heating chamber, where it is first heated and vaporized, then further vaporized through the upper side chamber, and finally sprayed out through the steam port 7 to heat the user's hair with steam.

[0044] In addition, the bottom plates of the first comb tooth module 1 and the second comb tooth module 12 are stacked, that is, the bottom of the comb tooth part 1 is plate-shaped, and the heating element is placed in close contact with the bottom of the comb tooth part 1 to heat the comb tooth part 1.

[0045] Traditional hair straighteners or combs primarily rely on the dry heat contact of heating plates (such as ceramic or titanium plates) to straighten hair. The physical mechanism involves breaking the hydrogen bonds in the hair keratin through high temperatures (typically 180°C-230°C), then deforming and rearranging the hair under pressure. After cooling, new hydrogen bonds are formed in the new morphology, thus achieving a styling effect.

[0046] However, the drawback of this method is: 1. Severe heat damage: High temperatures will rapidly evaporate the structural moisture inside the hair, causing keratin to become brittle and the hair cuticles to become scorched. Long-term use will cause the hair to become dry, split, and lose its shine.

[0047] 2. Low styling efficiency and unnatural results: For extremely curly, frizzy, or damaged hair, dry heat requires higher temperatures and multiple repeated operations to straighten it, resulting in a stiff effect that lacks natural smoothness.

[0048] 3. Poor moisture resistance: In humid environments, hair easily reabsorbs moisture from the air, damaging the hydrogen bond structure and causing the style to quickly fail.

[0049] This hair straightening comb, by incorporating a steam function, achieves the following effects when straightening hair: I. Steam reduces heat damage The thermal buffering effect of moisture Steam (100°C water vapor) can form a high-temperature water film on the surface of the hair, reducing direct heat damage through the following mechanisms: Uniform heat transfer: Steam has better thermal conductivity than dry heat, avoiding local overheating (such as "hot spots" caused by uneven contact of traditional clamps).

[0050] Gentle warming: When water vapor releases latent heat (heat of vaporization), the temperature stabilizes at around 100°C, slowing down the rate at which the hair heats up and reducing sudden denaturation of keratin.

[0051] Maintain hair moisture content Traditional high-temperature tools quickly evaporate the moisture inside the hair, causing the hair cuticles to dry and crack. Steam, on the other hand, can replenish moisture while heating, reducing cuticle lifting (reducing friction and static electricity).

[0052] Protection of disulfide bonds A steam environment may delay the breaking temperature of disulfide bonds (above 140°C), relying more on hydrogen bond recombination rather than covalent bond destruction in the 100-140°C range, thereby reducing permanent damage.

[0053] II. Steam Enhancement of Straight Hair Effect (Taking Straight Hair in Hair Styling as an Example) Enhance the plasticity of keratin When moisture penetrates the hair cortex, it weakens hydrogen bonds and temporarily stretches the keratin structure, making the hair more susceptible to stretching and deformation under external forces (such as the tension of a hair straightener). Experiments have shown that in environments with humidity levels above 50%, the yield strength of hair decreases by approximately 30%.

[0054] Temporary softening of hair cuticles Steam softens the cuticle layer of hair, making the hair surface smoother and reducing friction resistance when the flat iron is used, thereby improving the smoothness and shine of straightened hair.

[0055] Thermo-hydraulic synergy Steam stage (100℃): Opens the hair cuticles and softens the hair.

[0056] Combing stage (100-140℃): Styling is done when the hair is in a highly malleable state, requiring a lower temperature than traditional dry heat (180℃-230℃).
