Background Art

[0002] With the improvement of living standards, more and more people begin to pay attention to their own image and appearance. Especially for the need of hair styling, it has become more diversified and personalized. Therefore, various types of straightening combs have emerged on the market, from traditional manual combs to electric straightening combs. By heating the brush part of the comb, the hair is heated simultaneously during the combing process, so as to quickly achieve the straightening and smoothing effects of the hair.

[0003] However, the width between the comb teeth of the existing straightening combs is relatively large, resulting in poor straightening effect when the comb teeth comb the hair.

Content of the Utility Model

[0004] To solve the problem that the width between the comb teeth of the existing straightening combs is relatively large, resulting in poor straightening effect when the comb teeth comb the hair, the utility model provides a comb tooth structure and a straightening comb.

[0005] The solution of the utility model to solve the technical problem is to provide a comb tooth structure, which includes a heat-conducting plate and a heat-insulating plate arranged in a stacked manner. A plurality of first heat-insulating teeth and a plurality of through holes are arranged on the heat-insulating plate, and the plurality of first heat-insulating teeth and the plurality of through holes are arranged at intervals. A plurality of heat-conducting teeth are arranged on the heat-conducting plate, and each heat-conducting tooth correspondingly passes out from the through hole and is arranged at intervals with the first heat-insulating tooth. The height of the first heat-insulating tooth is greater than the exposed height of the heat-conducting tooth passing out of the through hole.

[0006] Preferably, the distance between adjacent heat-conducting teeth and the first heat-insulating teeth is 0.5 mm - 1.5 mm.

[0007] Preferably, the height difference between the height of the first heat-insulating tooth and the exposed height of the heat-conducting tooth is 2 mm - 6 mm.

[0008] Preferably, the heat-conducting tooth includes a main side surface and a secondary side surface, and the area of the main side surface is larger than that of the secondary side surface; the area of the surface of the first heat-insulating tooth opposite to the main side surface is larger than the area of the surface parallel to the secondary side surface; the plurality of first heat-insulating teeth and the plurality of through holes are arranged at intervals in a direction perpendicular to the main side surface.

[0009] Preferably, the direction perpendicular to the main side surface on the heat-conducting plate and the heat-insulating plate is defined as the length direction, and the direction parallel to the main side surface is defined as the width direction; the length of the tooth root end of the heat-conducting tooth passing out of the through hole in the width direction is the same as the length of the tooth root end of the first heat-insulating tooth in the width direction.

[0010] Preferably, the plurality of heat-conducting teeth and the plurality of first heat-insulating teeth are arranged in an array in a direction perpendicular to the main side surface, and the array includes at least two columns, and in each column, the plurality of heat-conducting teeth and the plurality of first heat-insulating teeth are arranged at intervals.

[0011] Preferably, the heat-conducting teeth in the same row in the width direction and the first heat-insulating teeth in the same row are both arranged in a non-linear manner.

[0012] Preferably, the first heat-insulating teeth are arranged at both ends of the array formed by the plurality of heat-conducting teeth and the first heat-insulating teeth.

[0013] Preferably, a plurality of second heat-insulating teeth are further arranged at intervals on the heat-insulating plate, and the plurality of second heat-insulating teeth enclose all the heat-conducting teeth and the first heat-insulating teeth.

[0014] Preferably, the second heat-insulating teeth are arranged opposite to the heat-conducting teeth arranged on the periphery.

[0015] Preferably, the height of the second heat-insulating teeth is greater than or equal to the exposed height of the heat-conducting teeth passing through the through holes.

[0016] Preferably, the cross-sectional areas of the heat-conducting teeth and the first heat-insulating teeth gradually increase from the tooth top end to the tooth root end.

[0017] The present utility model also provides a hair straightening comb for the solution to the technical problem. The hair straightening comb includes a handle, a comb tooth part, and a comb tooth structure as described in any one of the above on the comb tooth part. A heating device is arranged on the comb tooth part, and the heating device is connected to the heat-conducting plate.

[0018] Compared with the prior art, the comb tooth structure and the hair straightening comb of the present utility model have the following advantages:

[0019] 1. The present utility model provides a structure including a heat-conducting plate and a heat-insulating plate arranged in a stacked manner. The heat-insulating plate is provided with a plurality of first heat-insulating teeth and a plurality of through holes. The plurality of first heat-insulating teeth and the plurality of through holes are arranged at intervals. The heat-conducting plate is provided with a plurality of heat-conducting teeth. Each heat-conducting tooth correspondingly passes through a through hole and is arranged at intervals with the first heat-insulating teeth. The height of the first heat-insulating teeth is greater than the exposed height of the heat-conducting teeth passing through the through holes. By arranging each heat-conducting tooth to correspondingly pass through a through hole and be arranged at intervals with the first heat-insulating teeth, a double-layer interpenetrating design of the heat-conducting teeth and the first heat-insulating teeth is realized, so as to achieve a smaller comb-tooth gap between the heat-conducting teeth and the first heat-insulating teeth, enabling the hair to contact the heat-conducting teeth more fully and achieving a better straightening effect. In addition, by setting the height of the first heat-insulating teeth to be greater than the height of the heat-conducting teeth, when the user uses it, the top of the first heat-insulating teeth will contact the user's scalp first, and the top of the heat-conducting teeth will not contact the user's scalp, thus avoiding the situation that the top of the heat-conducting teeth burns the user's scalp due to excessive temperature when using a hair straightener including this comb-tooth structure, and further achieving a smaller comb-tooth gap between the heat-conducting teeth and the first heat-insulating teeth while avoiding the top of the heat-conducting teeth burning the user's scalp due to excessive temperature.

[0020] 2. The heat-conducting teeth of the present utility model include a main side surface and a secondary side surface. The area of the main side surface is larger than the area of the secondary side surface. The area of the surface of the first heat-insulating teeth opposite to the main side surface is larger than the area of the surface parallel to the secondary side surface; the plurality of first heat-insulating teeth and the plurality of through holes are arranged at intervals in a direction perpendicular to the main side surface. By setting the main side surface and the secondary side surface, the larger-area main side surface of the heat-conducting teeth and the larger-area surface of the corresponding first heat-insulating teeth form two opposite surfaces of the comb-tooth gap between adjacent heat-conducting teeth and first heat-insulating teeth, thereby maximizing the contact area and contact length between the hair and the main side surface in the comb-tooth gap, and further improving the combing and straightening effect on the hair.

[0021] 3. In the present utility model, the direction perpendicular to the main side surface on the heat-conducting plate and the heat-insulating plate is defined as the length direction, and the direction parallel to the main side surface is defined as the width direction; the length of the root end of the heat-conducting teeth passing through the through holes in the width direction is the same as the length of the root end of the first heat-insulating teeth in the width direction. This can make the interval arrangement of the heat-conducting teeth and the first heat-insulating teeth more regular, and at the same time make the surface areas of the main side surfaces of the heat-conducting teeth and the surfaces of the first heat-insulating teeth on the relative two sides of the comb-tooth gap maintain the same length as much as possible starting from the root end, so that the two sides of the comb-tooth gap can maintain the same hair limiting and clamping effect as much as possible, avoiding the situation that the two sides of the comb-tooth gap are of different lengths and affecting the combing and straightening effect on the hair.

[0022] 4. In the present utility model, the heat-conducting teeth and the first heat-insulating teeth in the same row along the width direction are both arranged in a non-linear manner. When the hair passes through the plurality of comb tooth gaps in the same row in sequence, it also passes through in a non-linear shape. Therefore, the hair can be arranged in a bent state among the plurality of comb tooth gaps as a whole, improving the stability of the hair arranged among the plurality of comb tooth gaps and avoiding the situation that the hair easily slips out of the comb tooth gaps.

[0023] 5. At both ends of the array formed by the plurality of heat-conducting teeth and the first heat-insulating teeth of the present utility model, the first heat-insulating teeth are arranged. Thus, the first heat-insulating teeth at both ends of the array isolate the outside from the heat-conducting teeth, avoiding scalding the user's skin by the heat-conducting teeth at the end.

[0024] 6. A plurality of second heat-insulating teeth are also arranged at intervals on the heat-insulating plate of the present utility model, and the plurality of second heat-insulating teeth enclose all the heat-conducting teeth and the first heat-insulating teeth. Thus, the heat-conducting teeth and the first heat-insulating teeth are both separated from the outside by the second heat-insulating teeth, avoiding the exposure of the heat-conducting teeth and preventing the occurrence of the situation where the heat-conducting teeth scald the user's skin.

[0025] 7. The second heat-insulating teeth of the present utility model are arranged opposite to the heat-conducting teeth arranged on the periphery. Thus, the situation that the heat-conducting teeth are exposed from the staggered gaps between the second heat-insulating teeth and the first heat-insulating teeth is avoided.

[0026] 8. The cross-sectional areas of the heat-conducting teeth and the first heat-insulating teeth of the present utility model gradually increase from the tooth tip to the tooth root end, thereby improving the overall strength of the heat-conducting teeth and the first heat-insulating teeth and avoiding breakage. In addition, the tips of the heat-conducting teeth and the first heat-insulating teeth can be made thinner, which is suitable for combing hair. Moreover, the comb tooth gaps between the heat-conducting teeth and the first heat-insulating teeth gradually decrease from the tooth tip to the tooth root end, improving the effect of combing and straightening the hair at the tooth root parts of the heat-conducting teeth and the first heat-insulating teeth.

[0027] 9. The present utility model also provides a hair straightening comb, which has the same beneficial effects as the above-mentioned comb tooth structure and will not be elaborated here.

For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to the specific circumstances.

[0045] Please refer to Figures 1 - 3 , a first embodiment of the present utility model provides a comb tooth structure 1, which includes a heat-conducting plate 11 and a heat-insulating plate 12 arranged in a stacked manner. A plurality of first heat-insulating teeth 121 and a plurality of through holes 122 are provided on the heat-insulating plate 12. The plurality of first heat-insulating teeth 121 and the plurality of through holes 122 are arranged at intervals. A plurality of heat-conducting teeth 111 are provided on the heat-conducting plate 11. Each heat-conducting tooth 111 correspondingly passes through the through hole 122 and is arranged at intervals with the first heat-insulating tooth 121. The height H (such as Figure 2 shown as H) of the first heat-insulating tooth 121 is greater than the exposed height h (such as Figure 2 shown as h) of the heat-conducting tooth 111 passing through the through hole 122.

[0046] Understandably, a plurality of first heat insulation teeth 121 and a plurality of through holes 122 can be provided on the heat insulation plate 12, and the plurality of first heat insulation teeth 121 and the plurality of through holes 122 can be arranged at intervals. The shape, size and position of the through hole 122 need to correspond to the shape, size and position of the heat conduction tooth 111, and the number of the through holes 122 also needs to correspond to the number of the heat conduction teeth 111; moreover, the arrangement mode of the plurality of through holes 122 on the heat insulation plate 12 and the distance between adjacent through holes 122 also need to be consistent with the arrangement mode of the plurality of heat conduction teeth 111 on the heat conduction plate 11 and the distance between adjacent heat conduction teeth 111, so that the plurality of heat conduction teeth 111 on the heat conduction plate 11 can pass through the corresponding through holes 122 and be arranged at intervals with the first heat insulation teeth 121. Thus, a double-layer interpenetrating design of the heat conduction teeth 111 and the first heat insulation teeth 121 is realized, so as to achieve a smaller comb tooth gap 13 between the heat conduction teeth 111 and the first heat insulation teeth 121, enabling the hair to contact the heat conduction teeth 111 more fully, so as to achieve a better straightening effect. In addition, since the comb tooth gap 13 between the heat conduction teeth 111 and the first heat insulation teeth 121 becomes smaller, the number of hair strands in a single comb tooth gap 13 becomes smaller, that is, the amount of hair in each comb tooth gap 13 becomes smaller, and single-sided heating can completely provide the required heat, that is, it is realized that while reducing the comb tooth gap 13, the same combing and straightening effect on the hair can be achieved.

[0047] Specifically, the height H of the first heat insulation tooth 121 can be greater than the exposed height h of the heat conduction tooth 111 after passing through the through hole 122. When a hair styling device with this comb tooth structure 1 is used by a user, the tooth tip of the first heat insulation tooth 121 will first contact the user's scalp, and the tooth tip of the heat conduction tooth 111 will not directly contact the user's scalp, thus avoiding the situation that when the hair styling device including this comb tooth structure 1 is used, the tooth tip of the heat conduction tooth 111 scalds the user's scalp due to too high temperature, and further realizing a smaller comb tooth gap 13 between the heat conduction teeth 111 and the first heat insulation teeth 121 while avoiding the tooth tip of the heat conduction tooth 111 scalding the user's scalp due to too high temperature. In addition, due to the laminated arrangement of the heat conduction plate 11 and the heat insulation plate 12, except that the heat conduction teeth 111 can be exposed through the through holes 122, other areas of the heat conduction plate 11 except the heat conduction teeth 111 are covered by the heat insulation plate 12, so that other parts of the heat insulation plate 12 except the heat conduction teeth 111 are isolated from the outside. Therefore, when combing the hair, it is avoided that other areas of the heat conduction plate 11 except the heat conduction teeth 111 contact the hair, and it is realized that only the heat conduction teeth 111 are used to heat and comb the hair, so as to balance the combing effect on the hair and avoid the situation that the hair near the tooth root end of the comb tooth gap 13 close to the heat conduction tooth 111 is heated on multiple sides by the heat conduction teeth 111 and the heat insulation plate 12, while the hair near the tooth tip of the heat conduction tooth 111 can only be heated by the heat conduction teeth 111, resulting in two unbalanced heating effects.

[0048] Optionally, the heat insulation plate 12 and the first heat insulation teeth 121 can be integrally formed, and the heat conduction plate 11 and the heat conduction teeth 111 can also be integrally formed, so as to enhance the overall strength of the heat insulation plate 12 and the first heat insulation teeth 121, as well as the overall strength of the heat conduction plate 11 and the heat conduction teeth 111, and further improve the strength and stability of the overall structure. The heat insulation plate 12 and the first heat insulation teeth 121 can be a silica gel plate and the first silica gel teeth made of silica gel material, which can withstand relatively high temperatures and are not easily deformed. The heat conduction plate 11 and the heat conduction teeth 111 can be a metal plate and metal teeth made of metal material, which have high thermal conductivity and are convenient for heating, combing, and straightening hair.

[0049] Furthermore, the distance between adjacent heat conduction teeth 111 and the first heat insulation teeth 121 is 0.5 mm - 1.5 mm.

[0050] It can be understood that by the interspersed arrangement of the two different types of comb teeth of the heat conduction teeth 111 and the first heat insulation teeth 121, the distance between adjacent heat conduction teeth 111 and the first heat insulation teeth 121 can be 0.5 mm - 1.5 mm. Compared with the distance of the existing comb teeth gap, the distance of the comb teeth gap in this embodiment is smaller, and the hair can contact the heat conduction teeth 111 more fully to achieve a better straightening effect.

[0051] Furthermore, the height difference between the height H of the first heat insulation teeth 121 and the exposed height h of the heat conduction teeth 111 is 2 mm - 6 mm.

[0052] It can be understood that when the height difference between the height H of the first heat insulation teeth 121 and the exposed height h of the heat conduction teeth 111 is 2 mm - 6 mm, an effective height difference is formed between the first heat insulation teeth 121 and the heat conduction teeth 111. Thus, the situation that the top of the teeth of the heat conduction teeth 111 scalds the user's scalp due to excessive temperature during the use of the hair styling device including the comb tooth structure 1 can be effectively avoided by the first heat insulation teeth 121.

[0053] Please refer to Figure 3 , furthermore, the heat conduction teeth 111 include a main side surface 1111 and a secondary side surface 1112, and the area of the main side surface 1111 is larger than the area of the secondary side surface 1112; the area of the surface of the first heat insulation teeth 121 opposite to the main side surface 1111 is larger than the area of the surface parallel to the secondary side surface 1112; a plurality of first heat insulation teeth 121 and a plurality of through holes 122 are arranged at intervals in a direction perpendicular to the main side surface 1111.

[0054] Understandably, the larger surface area on the heat-conducting tooth 111 is the main side surface 1111, and the two surfaces adjacent to the main side surface 1111 are the secondary side surfaces 1112, and the area of the secondary side surface 1112 is smaller than that of the main side surface 1111. Correspondingly, the area of the surface of the first heat-insulating tooth 121 that is directly opposite to the main side surface 1111 of the heat-conducting tooth 111 is larger than the area of the surface that is parallel to the secondary side surface 1112 of the heat-conducting tooth 111. Thus, one pair of opposite surfaces of each comb tooth gap 13 is composed of the larger main side surface 1111 of the heat-conducting tooth 111 and the relatively larger surface of the corresponding first heat-insulating tooth 121, thereby increasing as much as possible the contact area and contact length between the hair and the main side surface 1111 in the comb tooth gap 13, and further improving the combing and straightening effect on the hair.

[0055] Please refer to and combine Figure 3 and Figure 4 , further, define the direction perpendicular to the main side surface 1111 on the heat-conducting plate 11 and the heat-insulating plate 12 as the length direction f1 (as shown by f1 in Figure 2 ), and the direction parallel to the main side surface 1111 as the width direction f2 (as shown by f2 in Figure 2 ); the length D (as shown by D in Figure 4 ) of the root end of the heat-conducting tooth 111 passing through the through hole 122 in the width direction f2 is the same as the length d (as shown by d in Figure 4 ) of the root end of the first heat-insulating tooth 121 in the width direction f2.

[0056] Understandably, define the direction perpendicular to the main side surface 1111 on the heat-conducting plate 11 and the heat-insulating plate 12 as the length direction f1, that is, define the facing direction of the main side surface 1111 as the length direction f1. When the length D of the root end of the heat-conducting tooth 111 passing through the through hole 122 in the width direction f2 is the same as the length d of the root end of the first heat-insulating tooth 121 in the width direction f2, the heat-conducting tooth 111 and the first heat-insulating tooth can be aligned starting from the root end, and the overall lengths of the heat-conducting tooth 111 and the first heat-insulating tooth in the width direction f2 are kept as consistent as possible, so that the spaced arrangement of the heat-conducting tooth 111 and the first heat-insulating tooth can be more regular. And the main side surfaces 1111 of the heat-conducting tooth 111 on the opposite sides of each comb tooth gap 13 and the surfaces of the first heat-insulating tooth 121 can start from the root end and keep the same length as much as possible, so that the two sides of the comb tooth gap 13 can limit and clamp the hair with the same clamping length as much as possible, avoiding the situation that the clamping lengths on both sides of the comb tooth gap 13 are different, which affects the clamping effect and thus affects the hair combing and straightening effect.

[0057] Please refer to Figure 4, Further, a plurality of heat-conducting teeth 111 and a plurality of first heat-insulating teeth 121 are arranged in an array along a direction perpendicular to the main side surface 1111. The array includes at least two columns, and in each column, the plurality of heat-conducting teeth 111 and the plurality of first heat-insulating teeth 121 are arranged at intervals.

[0058] It can be understood that the plurality of first heat-insulating teeth 121 provided on the heat-insulating plate 12 can be arranged in an array along a direction perpendicular to the main side surface 1111. The array includes at least two columns of first heat-insulating teeth 121. And through holes 122 are provided between every two adjacent heat-conducting teeth 111 in each column, so that the plurality of through holes 122 and the plurality of first heat-insulating teeth 121 are arranged in an array of at least two columns. The heat-conducting teeth 111 on the heat-conducting plate 11 are correspondingly arranged, so that after passing through the through holes 122, they are arranged in an array of at least two columns with the plurality of first heat-insulating teeth 121. In each column, the plurality of heat-conducting teeth 111 and the plurality of first heat-insulating teeth 121 are arranged at intervals. Thus, the interspersed design of the heat-conducting teeth 111 and the first heat-insulating teeth 121 along the length direction is realized, so as to achieve a smaller comb tooth gap 13 between the heat-conducting teeth 111 and the first heat-insulating teeth 121, enabling the hair to contact the heat-conducting teeth 111 more fully, so as to achieve a better straightening effect. In addition, the array arrangement can make the plurality of main side surfaces 1111 of the plurality of heat-conducting teeth 111 be set at the same orientation angle, so as to more evenly heat and comb the hair entering the gap in each comb tooth gap 13.

[0059] Optionally, in this embodiment, the array may include two columns, three columns, four columns, etc. Setting a smaller number of columns such as two columns or three columns can make the structure smaller in volume, lighter in weight, and easier to carry. Specifically, the number of columns of the comb tooth structure 1 is selected according to the specific use scenario, and this embodiment does not limit this. In this embodiment, it is preferably that the array may include four columns, with the two outer columns on both sides of the two inner columns, surrounding the two inner columns. Thus, the setting of four columns can increase the length of heating, combing and straightening the hair at one time, so as to improve the combing efficiency.

[0060] Please refer to Figure 4 , Further, the heat-conducting teeth 111 in the same row along the width direction and the first heat-insulating teeth 121 in the same row are both arranged in a non-linear manner.

[0061] It can be understood that by setting the heat-conducting teeth 111 in the same row and the first heat-insulating teeth 121 in the same row in the array along the width direction to be both arranged in a non-linear manner, when the hair passes through the plurality of comb tooth gaps 13 in the same row in sequence, it also passes through in a non-linear shape. Therefore, the hair can be integrally arranged in a bent form among the plurality of comb tooth gaps 13, improving the stability of the hair arranged among the plurality of comb tooth gaps 13 and avoiding the situation that the hair is easily slipped out of the comb tooth gaps 13.

[0062] Please refer to Figure 3, Further, first heat insulation teeth 121 are arranged at both ends of the array formed by multiple heat conduction teeth 111 and the first heat insulation teeth 121.

[0063] It can be understood that since multiple first heat insulation teeth 121 and multiple heat conduction teeth 111 are arranged in an array along the direction perpendicular to the main side surface 1111, therefore, to avoid scalding the user by the main side surface 1111 at the ports at both ends of the array, that is, to avoid scalding the user by the main side surface 1111 at the head and tail of the array, first heat insulation teeth 121 can be arranged at the ports at both ends of the array, so as to isolate the main side surface 1111 from the outside world and avoid scalding the user's skin by the heat conduction teeth 111 at the head and tail of the array.

[0064] Please refer to Figure 1 and Figure 4 , Further, a plurality of second heat insulation teeth 123 are also arranged at intervals on the heat insulation plate 12, and the plurality of second heat insulation teeth 123 enclose all the heat conduction teeth 111 and the first heat insulation teeth 121.

[0065] It can be understood that all the heat conduction teeth 111 and the first heat insulation teeth 121 are enclosed by a plurality of second heat insulation teeth 123 arranged at intervals, so that the heat conduction teeth 111 and the first heat insulation teeth 121 are separated from the outside world by the second heat insulation teeth 123. Even if the user's skin or scalp contacts the comb tooth structure 1 in the width direction or length direction of the heat conduction teeth 111, it will first contact the second heat insulation teeth 123 and be blocked by the second heat insulation teeth 123, and will not directly contact the heat conduction teeth 111, thereby avoiding scalding the user's skin caused by the exposure of the heat conduction teeth 111. In addition, due to the arrangement of the second heat insulation teeth 123, the direction from the outside to the inside at both ends of the array is the second heat insulation teeth 123, the first heat insulation teeth 121, and the heat conduction teeth 111 in sequence. Thus, a double protection composed of the second heat insulation teeth 123 and the first heat insulation teeth 121 is realized to ensure that the two ends of the comb tooth structure 1 in the direction perpendicular to the main side surface 1111 will not scald the user.

[0066] Please refer to Figure 4 , Further, the second heat insulation teeth 123 are arranged opposite to the heat conduction teeth 111 arranged on the periphery.

[0067] It can be understood that when the plurality of second heat insulation teeth 123 enclose the heat conduction teeth 111 and the first heat insulation teeth 121, they also need to be arranged opposite to the heat conduction teeth 111 arranged in the periphery of the array, so as to avoid the situation that the heat conduction teeth 111 are exposed from the staggered gaps between the second heat insulation teeth 123 and the first heat insulation teeth 121 through the second heat insulation teeth 123.

[0068] Please refer to Figure 2 , Further, the height L of the second heat insulation teeth 123 (such as Figure 2The height L shown is greater than or equal to the exposed height h of the heat-conducting tooth 111 passing through the through hole 122. Thus, the heat-conducting tooth 111 is completely isolated from the outside world by the second heat-insulating tooth 123, and the heat-conducting tooth 111 is prevented from being higher than the second heat-insulating tooth 123 and having exposed parts. In this way, the heat-conducting tooth 111 is isolated from the outside world, and the heat-insulating effect of the second heat-insulating tooth 123 on the heat-conducting tooth 111 is further improved.

[0069] See also Figure 1 Furthermore, the cross-sectional areas of the heat-conducting teeth 111 and the first heat-insulating teeth 121 gradually increase from the tooth top to the tooth root. This improves the overall strength of the heat-conducting teeth 111 and the first heat-insulating teeth to avoid breakage. In addition, the tips of the heat-conducting teeth 111 and the first heat-insulating teeth can be made thinner, which is suitable for combing hair. In addition, the combing tooth gap 13 between the heat-conducting teeth 111 and the first heat-insulating teeth 121 can be gradually reduced from the tooth top to the tooth root, thereby improving the limiting effect of the tooth roots of the heat-conducting teeth 111 and the first heat-insulating teeth 121 on the hair, thereby improving the combing and straightening effect on the hair.

[0070] See also Figure 5 and Figure 6 The second embodiment of the utility model provides a hair straightening comb 2, which includes a handle 21, a comb tooth portion 22, and a comb tooth structure 1 as described in any one of the first embodiments arranged on the comb tooth portion 22, and a heating device 23 is arranged on the comb tooth portion 22, and the heating device 23 is connected to the heat conducting plate 11.

[0071] It can be understood that the handle 21 is used for the user to grasp and hold, and the comb tooth portion 22 is provided with a heating device 23, which is stacked with the heat conducting plate 11 in the comb tooth structure 1, that is, it is arranged on the side of the heat conducting plate 11 away from the heat conducting teeth 111, and is attached to the side, so that the heat conducting plate 11 is heated by the heating device 23. Optionally, the heating device 23 can be a PTC heater, which can heat quickly and evenly when powered, so that the hair straightening process is more efficient and quick. Since the hair straightening comb 2 includes the comb tooth structure 1 in the first embodiment, it has the same beneficial effects as the comb tooth structure 1, which will not be described in detail here.

[0072] Compared with the prior art, the comb tooth structure and hair straightening comb of the utility model have the following advantages:

[0073] 1. The present utility model provides a structure including a thermally conductive plate and a heat insulating plate arranged in a stacked manner. The heat insulating plate is provided with a plurality of first heat insulating teeth and a plurality of through holes, and the plurality of first heat insulating teeth and the plurality of through holes are arranged at intervals. The thermally conductive plate is provided with a plurality of thermally conductive teeth, and each thermally conductive tooth correspondingly passes through a through hole and is arranged at intervals with the first heat insulating teeth. The height of the first heat insulating teeth is greater than the exposed height of the thermally conductive teeth passing through the through holes. By arranging each thermally conductive tooth to correspondingly pass through a through hole and be arranged at intervals with the first heat insulating teeth, a double-layer interpenetrating design of the thermally conductive teeth and the first heat insulating teeth is realized, so as to achieve a smaller comb tooth gap between the thermally conductive teeth and the first heat insulating teeth, enabling the hair to come into fuller contact with the thermally conductive teeth and achieving a better straightening effect. In addition, by setting the height of the first heat insulating teeth to be greater than the height of the thermally conductive teeth, when the user uses it, the top of the first heat insulating teeth will contact the user's scalp first, rather than the top of the thermally conductive teeth contacting the user's scalp, thus avoiding the situation that the top of the thermally conductive teeth scalds the user's scalp due to excessive temperature during the use of the straightening comb including this comb tooth structure, and further achieving a smaller comb tooth gap between the thermally conductive teeth and the first heat insulating teeth while avoiding scalding of the user's scalp by the top of the thermally conductive teeth due to excessive temperature.

[0074] 2. The thermally conductive teeth of the present utility model include a main side and a secondary side, and the area of the main side is greater than the area of the secondary side; the area of the surface of the first heat insulating teeth opposite to the main side is greater than the area of the surface parallel to the secondary side; the plurality of first heat insulating teeth and the plurality of through holes are arranged at intervals in a direction perpendicular to the main side. By setting the main side and the secondary side, the main side with a larger area in the thermally conductive teeth and the surface with a larger area in the corresponding first heat insulating teeth form a pair of opposite surfaces of the comb tooth gap between adjacent thermally conductive teeth and first heat insulating teeth, thereby maximizing the contact area and contact length between the hair in the comb tooth gap and the main side, and further improving the combing and straightening effect on the hair.

[0075] 3. In the present utility model, the direction perpendicular to the main side on the thermally conductive plate and the heat insulating plate is defined as the length direction, and the direction parallel to the main side is defined as the width direction; the length of the root end of the thermally conductive teeth passing through the through holes in the width direction is the same as the length of the root end of the first heat insulating teeth in the width direction. This can make the interval arrangement of the thermally conductive teeth and the first heat insulating teeth more regular, and at the same time make the surface areas of the main sides of the thermally conductive teeth and the surfaces of the first heat insulating teeth on the relative two sides of the comb tooth gap maintain the same length as much as possible starting from the root end, so that the two sides of the comb tooth gap can maintain the same limiting and clamping effect on the hair as much as possible, avoiding the situation that the two sides of the comb tooth gap are of different lengths and affecting the combing and straightening effect on the hair.

[0076] 4. The heat-conducting teeth and the first heat-insulating teeth in the same row along the width direction of the present utility model are both arranged in a non-linear manner. When the hair passes through the comb teeth gaps in the same row in sequence, it also passes through in a non-linear shape. Therefore, the hair can be arranged in a curved shape among multiple comb teeth gaps as a whole, improving the stability of the hair arranged among multiple comb teeth gaps and avoiding the situation that the hair easily slips out of the comb teeth gaps.

[0077] 5. The first heat-insulating teeth are arranged at both ends of the array formed by multiple heat-conducting teeth and the first heat-insulating teeth of the present utility model. Thus, the first heat-insulating teeth at both ends of the array isolate the outside from the heat-conducting teeth, avoiding scalding the user's skin by the heat-conducting teeth at the end.

[0078] 6. A plurality of second heat-insulating teeth are also arranged at intervals on the heat-insulating plate of the present utility model, and the plurality of second heat-insulating teeth enclose all the heat-conducting teeth and the first heat-insulating teeth. Thus, the second heat-insulating teeth separate both the heat-conducting teeth and the first heat-insulating teeth from the outside, avoiding the exposure of the heat-conducting teeth and preventing the occurrence of the situation where the heat-conducting teeth scald the user's skin.

[0079] 7. The second heat-insulating teeth of the present utility model are arranged opposite to the heat-conducting teeth arranged on the periphery. Thus, the situation that the heat-conducting teeth are exposed from the staggered gaps between the second heat-insulating teeth and the first heat-insulating teeth is avoided.

[0080] 8. The cross-sectional areas of the heat-conducting teeth and the first heat-insulating teeth of the present utility model gradually increase from the tooth tip to the tooth root end, thereby improving the overall strength of the heat-conducting teeth and the first heat-insulating teeth and avoiding breakage. In addition, the tips of the heat-conducting teeth and the first heat-insulating teeth can be made thinner, which is suitable for combing hair. Moreover, the comb teeth gaps between the heat-conducting teeth and the first heat-insulating teeth gradually decrease from the tooth tip to the tooth root end, improving the effect of combing and straightening the hair at the tooth root parts of the heat-conducting teeth and the first heat-insulating teeth.

[0081] 9. The present utility model also provides a hair straightening comb, which has the same beneficial effects as the above-mentioned comb tooth structure and will not be elaborated here.

[0082] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the principle of the present utility model shall be included within the protection scope of the present utility model.
