Description

[Technical Field]

[0001] This invention relates to the field of hair styling technology, and in particular to a comb plate and a hair styling tool. [Background Technology]

[0002] In daily life, due to differences in hair quality, especially for those with fine, thin hair, the hair often lies flat against the scalp, making the overall head shape less attractive. To address this issue, hair styling tools designed to add volume have been developed. These tools feature a toothed clamping mechanism that heats the hair while clamping it, causing it to curl and gain volume, preventing it from lying flat against the scalp. This visually increases hair volume and improves the overall head shape. However, most hair styling tools on the market are currently designed to be straight, such as... Figure 1 The image shows a straight hair styling tool. After using the straight hair styling tool to curl the hair, although the resulting hairstyle achieves a fluffy effect, it looks rather square, which affects the aesthetics. [Summary of the Invention]

[0003] To address the problem of poor hair styling results in existing hair styling devices, this invention provides a comb plate and a hair styling device.

[0004] The solution to the technical problem of the present invention is to provide a comb plate, the comb plate including a heating plate and protruding teeth disposed on the heating plate, the protruding teeth being arranged in rows, wherein at least one row of protruding teeth is arranged in an arc shape.

[0005] Preferably, the side of the hot plate near the arc-shaped protrusions is arc-shaped, and the curvature of this side matches the curvature of a row of arc-shaped protrusions.

[0006] Preferably, each row of protruding teeth is arranged in an arc shape.

[0007] Preferably, the hot plate includes a first side and a second side that are located near the side with protruding teeth and are disposed opposite to each other, and both the first side and the second side are arc-shaped and the curvatures match.

[0008] Preferably, the protruding teeth are configured as a hollow structure.

[0009] Preferably, the top surface of the protruding teeth away from the hot plate is configured as a concave curved surface.

[0010] Preferably, the side adjacent to the top surface on the protruding tooth is defined as the side surface, the junction of the top surface and the side surface is rounded, and the junction between two adjacent side surfaces is also rounded.

[0011] The present invention also provides a hair styling tool, including two clamp arms and a comb plate as described above disposed on one or both clamp arms, wherein the side of the clamp arm near the arc-shaped protrusions is arc-shaped.

[0012] Preferably, the curvature of the arc-shaped side of the clamping arm is consistent with the curvature of a row of comb teeth arranged in an arc shape.

[0013] Preferably, the other side of the clamping arm opposite to the arc-shaped side is also arc-shaped, and the curvature of the two sides matches.

[0014] Preferably, a heating element is also provided inside the clamping arm, and the heating element is located on the back side of the heating plate away from the protruding teeth.

[0015] Preferably, after the two clamping arms are clamped together, the top surface of the protruding tooth abuts against the working surface of the other clamping arm, and the part on the clamping arm that abuts against the top surface of the protruding tooth of the other clamping arm is defined as the abutting part, wherein the abutting part matches the shape of the top surface.

[0016] Preferably, adjacent teeth on the same clamping arm are spaced apart and do not contact each other; and after the two clamping arms are clamped together, the teeth on the two clamping arms do not contact each other, and there is a gap between adjacent teeth.

[0017] Preferably, a protrusion is provided on the bent and recessed side of the clamping arm, the protrusion being configured to have a smooth surface, and the protrusion being multiple and spaced apart.

[0018] Preferably, the curvature of the arcuate side of the clamping arm is in the range of 1 / 0.3-1 / 0.07.

[0019] Compared with the prior art, the comb plate and hair styling tool provided by the present invention have the following advantages:

[0020] 1. The comb plate provided in this embodiment of the invention, due to the curvature of the comb plate, allows it to better conform to the shape of the human head, and better clamp and style the hair at the roots. This ensures that the hair is clamped and styled at the roots, supporting it and creating a voluminous effect, thus reducing oiliness. Furthermore, during styling, the concave arc contour of the curved comb plate better matches the convex arc of the head shape. This ensures that the distance between the clamped portion of the hair and the hair roots is equal during styling, resulting in an overall head shape that more closely resembles the convex arc contour of the head. This solves the problem of straight comb plates failing to match the convex arc of the head shape, which instead results in a square shape after styling.

[0021] 2. A hair styling device provided in this embodiment of the invention, wherein a heating element is provided inside the clamping arm space, the heating element is in close contact with the toothed ironing plate to provide the heat required for styling to the toothed ironing plate, when the two clamping arms are in contact, the protruding teeth of the upper and lower ironing plates fit together, clamping the hair between the mating surfaces and heating it, thereby making the clamped hair achieve the same shape as the protruding teeth.

[0022] 3. The hair styling tool provided in this embodiment of the invention has a curved top surface for the protruding teeth, and the abutting part fits with the top surface. When the hair is curled, the curved surface of the hair can have a certain aesthetic curvature instead of a straight shape, further avoiding the drawback of making a square head shape and achieving an aesthetic effect.

[0023] 4. A hair styling tool provided in this embodiment of the invention, wherein the edges of the protruding teeth are all rounded to prevent cutting the hair and causing damage to the hair.

[0024] 5. The hair styling tool provided in this embodiment of the invention has gaps between adjacent protrusions after clamping, which avoids clamping the hair too tightly and causing hair breakage. At the same time, it can clamp and style a larger amount of hair at the same time, improving the hair styling efficiency.

[0025] 6. The hair styling device provided in this embodiment of the invention has a negative ion generator that continuously emits negative ions. While the hair is being heated and styled, the negative ions cover the surface of the hair, reducing hair damage caused by heat and making the hair smoother and shinier.

[0026] 7. The hair styling tool provided in this embodiment of the invention has a protrusion on one side of the bent and recessed arm. When in use, it can maintain the distance between the scalp and the protruding teeth, preventing burns to scalp cells and damage to the hair growth environment.

[0027] 8. A hair styling tool provided in this embodiment of the invention, wherein the protruding portion is further configured as a smooth surface. The smooth surface reduces the risk of injury to the hair and scalp from the protrusion, and at the same time, the smaller contact area with the scalp more effectively prevents burns to the skin.

[0028] 9. The hair styling tool provided in this embodiment of the invention has a clamp arm that is bent to form two opposite sides with a certain curvature, and the curvature of the two sides is equal, so that the distance between the two sides is equal at any position, and the protruding teeth are better set so that the part of the hair that is clamped and heated is the same length, resulting in a better aesthetic effect.

[0049] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

These terms are primarily for the purpose of better describing the invention and its embodiments, and are not intended to limit the indicated devices, elements, or components to having a specific orientation, or to be constructed and operated in a specific orientation.

[0052] Furthermore, in addition to indicating direction or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in certain situations to indicate a dependency or connection. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0053] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0054] Please combine Figures 2-3 The first embodiment of the present invention provides a comb plate 2, which includes a heating plate 111 and protruding teeth 116 disposed on the heating plate 111. The protruding teeth 116 are arranged in rows, wherein at least one row of protruding teeth 116 is arranged in an arc shape. The side of the heating plate 111 near the arc-shaped protruding teeth 116 is set in an arc shape, and the arc degree matches the arc degree of the arc-shaped protruding teeth 116.

[0055] Understandably, the row of protruding teeth 116 arranged in an arc shape is the outermost row, and the side of the heating plate 111 near this row of arc-shaped protruding teeth 116 is also arranged in an arc shape, which can better match the arc shape of the human head, so that this row of arc-shaped protruding teeth 116 can clamp the hair roots.

[0056] In one specific embodiment, each row of protruding teeth 116 is arranged in an arc shape, and the arc of each row of protruding teeth 116 is equal.

[0057] The heating plate 111 includes a first side 111a and a second side 111b arranged opposite to each other. The protruding teeth are arranged in rows along the extending direction of the first side 111a, and the first side 111a and the second side 111b are adjacent to each other with a protruding surface of the heating plate. Both the first side 111a and the second side 111b are arc-shaped. Each row of protruding teeth 116 is arc-shaped and adjacent protruding teeth 116 are spaced apart.

[0058] Understandably, during use, the curved arc of the comb plate 2 allows it to better conform to the shape of the human head, more effectively clamping and styling the hair at the roots. This ensures the hair is properly clamped and styled at the roots, providing support and creating a voluminous effect that prevents oiliness. Furthermore, the concave contour of the curved comb plate 2 better matches the convex shape of the head during styling. This ensures that the distance between the clamped portion and the hair roots is equal, resulting in a more closely approximate shape that mimics the convex contour of the head. This overcomes the drawback of straight comb plates, which cannot match the head's convex shape and instead result in a square-shaped style after styling.

[0059] Furthermore, if the first side 111a is defined as the concave side of the heating plate 111, then the length of the long side of the protruding tooth 116 near the first side 111a is less than the length of the long side near the second side 111b.

[0060] Understandably, such as Figure 2 As shown, the length of the protruding tooth 116 near the long side of the first side 111a is N, and the length of the protruding tooth 116 near the long side of the second side 111b is M. Since the hot plate 111 is bent, the length of the first side 111a is relatively short. The protruding tooth 116 needs to adapt to this bent structure. Therefore, when setting the protruding tooth 116, M is greater than N. There is no need to add extra protruding teeth 116 on the outside to utilize the outer space. The arrangement is reasonable.

[0061] Furthermore, the protruding teeth 116 located in the same row are equidistant from either the first side 111a or the second side 111b. Understandably, the advantage of this arrangement is that, when styling hair, the regular arrangement of the protruding teeth 116 ensures that the curled hair has a regular and attractive texture, rather than a messy and disorderly appearance.

[0062] In this embodiment, the curvature of the first side 111a and the second side 111b is equal, so that the spacing between these two opposing sides is equal at any position. The protruding teeth 116 are better set so that when in use, the part of the hair that is clamped and ironed is the same length, so that the hair has the same degree of fluffiness and a better aesthetic effect.

[0063] Furthermore, the protruding teeth are configured as hollow structures, wherein the protruding teeth 116 are configured as hollow structures, which reduces the volume of the protruding teeth 116, makes it easier to conduct heat, and is also lighter.

[0064] Furthermore, the top surface 1161 of the protruding teeth 116 away from the hot plate 111 is set as a concave curved surface. Compared with a flat or convex surface, the hair is less likely to slip to the side on the concave curved surface, which allows for better styling.

[0065] Furthermore, the area adjacent to the top surface 1161 on the protrusion 116 is defined as the side surface. The junction between the top surface 1161 and the side surface is rounded, and the junction between two adjacent side surfaces is also rounded. The edges of the protrusions are all rounded to prevent them from cutting or damaging the hair during use.

[0066] Please see Figures 4-6 The second embodiment of the present invention also provides a hair styling tool 1, including two clamping arms 11 and a comb plate 2 as described in the first embodiment disposed on one or both clamping arms 11, wherein the side of the clamping arm 11 near the arc-shaped protrusions is arc-shaped.

[0067] Furthermore, the curvature of the arc-shaped side of the clamp arm 11 is consistent with the curvature of the row of comb teeth arranged in an arc shape, so that the clamp arm 11 and the heating plate 111 cooperate with each other to conform to the arc-shaped contour of the human scalp.

[0068] One end of each of the two clamping arms 11 is rotatably connected, and the other end can clamp each other. The comb plate 2 is set on the opposite side of the clamping arms at the end where they can clamp each other.

[0069] Specifically, after the two clamping arms 11 are clamped together, the protruding teeth 116 on the two clamping arms 11 are interlaced; the adjacent side is defined as the side surface, and the ends of the two clamping arms 11 with protruding teeth 116 are bent toward the same side surface to form an arc-shaped clamping arm 11.

[0070] Understandably, during use, the hair is clamped and permed by the heatable protrusions 116 on the two clamp arms 11 that fit together. While the hair is heated, it is styled into a fluffy shape with ups and downs. During use, due to the curvature of the clamp arms 11, the clamp arms 11 can better fit the shape of the human head and better clamp and perm the roots of the hair, so that the hair can be permed and styled at the roots. The roots support the hair, and because the roots are supported after being permed, the hair becomes fluffy and therefore less prone to oiliness.

[0071] Because the clamp arm 11 is designed as a curved arc, the concave arc contour of the curved clamp arm 11 can better match the convex arc of the head shape during the perming process. This makes the distance between the perming part of the hair and the hair root equal during the perming process. The overall head shape after perming is more similar to the convex arc contour of the head shape, which solves the problem that straight plates cannot match the convex arc of the head shape during perming, and instead cause the whole style to become square after perming.

[0072] Understandably, comb plates 2 are provided on the working surfaces 115 of both clamping arms 11. In other embodiments, each protruding tooth 116 may be of equal size for easy arrangement. In this embodiment, the working surface 115 is a plane, and the height of each protruding tooth 116 relative to the working surface 115 is equal. After clamping, the protruding teeth 116 are interlaced with each other. That is, it can be understood that the protruding teeth 116 on one clamping arm 11 enter the gap between the protruding teeth 116 on the other clamping arm 11, thereby clamping and curling the hair to make it fluffy.

[0073] Specifically, in this embodiment, the hair styling device 1 further includes a hinge 13, through which the two clamping arms 11 are rotatably connected; at least one clamping arm 11 is rotatably connected to the hinge 13, wherein both clamping arms 11 can be rotatably connected to the hinge 13, or one clamping arm 11 is fixedly connected to the hinge 13, and the other clamping arm 11 is rotatably connected to the hinge 13, thereby enabling the other ends of the two clamping arms 11 to clamp each other; in other embodiments, a locking structure is also provided on the hinge 13 or on one of the clamping arms 11 to control the opening and closing between the two clamping arms 11. After the locking structure is locked, the two clamping arms 11 cannot be opened, and after the locking structure is unlocked, the two clamping arms 11 can be opened for use.

[0074] Please combine Figure 5 and Figure 11 Furthermore, the clamping arm 11 rotatably connected to the hinge 13 is defined as the movable clamping arm. The hinge 13 includes a support portion 131, which is located between the two clamping arms 11. A limiting groove 1311 is formed on the side of the support portion 131 corresponding to the movable clamping arm. A limiting part 119 is also provided on the movable clamping arm at the position corresponding to the limiting groove 1311. When the two clamping arms 11 are clamped together, the movable clamping arm abuts against the support portion 131, and the limiting part 119 is located in the limiting groove 1311 and abuts against the inner wall of the limiting groove 1311.

[0075] Understandably, the support portion 131 can be used to support the clamping arm 11 and prevent the front end of the clamping arm 11 with the toothed protrusion 116 from misaligning and swinging. When the two clamping arms 11 are clamped together, the limiting portion 119 is located in the limiting groove 1311 and abuts against the inner wall of the limiting groove 1311, which can further prevent the clamping arm 11 from swinging in any direction other than the opening and closing direction.

[0076] Furthermore, an elastic element 1312 is also provided in the limiting groove 1311, with one end of the elastic element 1312 abutting the bottom of the limiting groove 1311 and the other end abutting the movable clamping arm.

[0077] Understandably, the elastic element 1312 is used to support the opening of the two clamping arms 11. That is, when the user is using the hair styling tool 1 to curl the hair, the user applies force to keep the two clamping arms 11 in a closed state. After use, the user releases the force applied to the clamping arms 11, and the two clamping arms 11 return to the open state due to the elastic force of the elastic element 1312.

[0078] Furthermore, the hair styling device 1 also includes a cord tail 14 rotatably connected to the hinge 13. Understandably, the cord tail 14 is the end of a power cord (not shown) and is used to connect to an external power source to provide electrical energy for the hair styling device 1 to operate. The cord tail 14 is rotatable to facilitate the actual use of the hair styling device 1.

[0079] In some other embodiments, one end of the two clamping arms 11 can also be directly and movably connected together to achieve a movable connection.

[0080] Please continue reading. Figure 5 , Figure 5 Figure A is a schematic diagram of the state when the two clamping arms 11 on the hair stylist 1 are clamped together. At this time, the two clamping arms 11 are parallel to each other, so the working surfaces 115 are parallel to each other, and the protrusions 116 on the two clamping arms 11 are intersecting. Figure 5 Figure B is a schematic diagram of the two clamping arms 11 of the hair stylist 1 after they are opened. The two clamping arms 11 have a certain angle α between them. When the hair stylist 1 is in use, the angle α can reach a maximum of 15°. Therefore, the range of the angle α is 0°-15°. The distance between the nearest protrusions on the two clamping arms is 0-30mm.

[0081] Combined Figures 5-8 Furthermore, the curved clamping arms form two opposing curved sides, with equal curvature on both sides; the curved clamping arms form two opposing sides with a certain degree of curvature, such as... Figure 7 As shown, the two opposite sides are named the first side 117a and the second side 117b, respectively. The first side 117a is a concave surface relative to the entire clamping arm 11, while the second side 117b is a convex surface relative to the entire clamping arm 11. In this embodiment, the curvature of the two sides is equal.

[0082] Understandably, the curvature of these two sides can be equal, so the curved part of the clamp arm can be regarded as part of a ring, so that the spacing between the two opposite sides at any position is equal, and the protruding teeth 116 are better set so that when in use, the part of the hair that can be clamped by the hair stylist 1 is of the same length, so that the hair has the same degree of fluffiness and a better aesthetic effect.

[0083] Furthermore, such as Figure 8The diagram of the human head shown in Figure a illustrates that the top shape of most human heads is close to a sphere with a diameter D = 140-160 mm. Figure 8 In the context of b, the curvature of hair varies greatly depending on its location on the head. For example, hair closer to the ears is flatter, resembling a larger circle with a smaller curvature. Therefore, the overall shape of the head conforms to a circle with a radius ranging from 70mm to 300mm. Thus, based on the different head shapes that the hair styling tool 1 adapts to, the average curvature range of the bend is 1 / 0.3 to 1 / 0.07, which means the curvature range of the curved side of the clamp arm is 1 / 0.3 to 1 / 0.07. The curvature of each point on the clamp arm 11 can be set to be different.

[0084] The curvature range of the opposite first side 111a and second side 111b of the comb plate 2 can be matched with the bending curvature of the clamping arm, and the value is 1 / 0.3-1 / 0.07.

[0085] To make it convenient for different users, the hair styling tool can be either a small or a larger model, making it easier to carry or use, allowing users to curl more hair at once.

[0086] Therefore, the bending arc of the clamp arm 11 in this invention is a curve that fits the shape of the human head, so that it can fit the scalp better during use and make it easier to curl the roots of the hair to make it fluffy. The bending direction is towards the side adjacent to and perpendicular to the working surface 115. In this way, during use, the first side 117a with an arc is formed by bending to fit the scalp, then the roots of the hair are clamped to make them perpendicular to the scalp, and then the hair is curled by the curling plate 111 to achieve a fluffy effect.

[0087] Furthermore, a space is formed inside the clamping arm 11, and an opening 1151 is provided on the working surface 115. The heating plate 111 is located in the space and closes the opening 1151, while the protruding teeth 116 are exposed outside the space. This allows the comb plate 2 to be fixed more firmly.

[0088] A heating element 112 is also provided in the space. The heating element 112 is located on the back of the heating plate 111 away from the protrusions 116, and the heating element 112 is used to heat the heating plate 111 and the protrusions 116 formed on the heating plate 111.

[0089] The heating plate 111 and the protruding teeth 116 are made of high-temperature resistant and highly conductive materials with excellent thermal conductivity, such as aluminum alloy die castings. The heating plate 11 is the working part on the clamping arm 11 that realizes the hair clamping and heating. The heating element 112 is used to control the heating of the heating plate 111 and the protruding teeth 116. In the actual hair styling tool 1 product, the hair styling tool 1 has a switch that can simultaneously control the working temperature of the heating element 112 on both clamping arms 11, which is convenient for users.

[0090] The heating element 112 is in close contact with the hot plate 111 to provide the heat required for styling. When the two clamping arms 11 are in contact, the protrusions 116 of the hot plate 111 on the upper and lower clamping arms 11 engage with each other, clamping the hair between the working surfaces 115 and heating it, so that the hair being clamped and heated can achieve the same shape as the protrusions 116.

[0091] Understandably, the shape of the hot plate 111 can be set to conform to the bending shape of the clamp arm 11, or it can be set to be curved. In this embodiment, the side of the hot plate 111 with the protruding teeth 116 is arc-shaped, so that the overall head shape after the hair is curled can be more similar to the outward arc contour of the head, achieving an aesthetic effect.

[0092] Combined Figure 4 In other embodiments, the hair styling tool 1 may also be equipped with a temperature indicator light (not shown), specifically located on one of the clamping arms 11, to remind the user of the temperature reached by the heating plate 111 during use. Specifically, the temperature indicator light can display different colors of light to remind the user of the current temperature of the heating plate 111. In other embodiments, the hair styling tool 1 also has a temperature control function, with a temperature control switch 110 located on one of the clamping arms 11 to facilitate user control of the hair styling temperature. Preferably, the temperature indicator light (not shown) and the temperature control switch 110 are located on the same clamping arm 11 and on the same side of the clamping arm 11, so that the user can easily see the currently selected working temperature when adjusting the working temperature of the hair styling tool 1.

[0093] When the heating element 112 is working, it generates heat and then conducts the heat to the heating plate 111 and the protruding teeth 116 for perming the hair. Specifically, in this embodiment, at least one temperature sensing element 118 is also provided in the space. The temperature sensing element 118 is attached to the heating plate 111 and is used to sense temperature changes. Specifically, the heating element 112 is a PTC heating element, and the temperature sensing element 118 is an NTC thermistor.

[0094] In this embodiment, the hair styling device 1 is equipped with three adjustable working temperatures, including 160°, 180° and 200°. When using the hair styling device 1, the user sets the desired working temperature using the temperature control switch 110. When the hair styling device 1 starts heating, the temperature sensing element 118 senses the temperature of the heating plate 111. When the heating plate 111 reaches the temperature preset by the user, the heating element 112 stops increasing the temperature of the heating plate 111 and keeps the temperature of the heating plate 111 at the set temperature.

[0095] Please combine Figure 6 , Figures 12-13 Specifically, in this embodiment, the space of the clamping arm 11 also includes a locking member 113. The locking member 113 is located on the side of the heating element 112 away from the heating plate 111, and the locking member 113 is detachably connected to the heating plate 111. The locking member 113 is used to firmly fix the heating element 112 against the heating plate 111 to facilitate heat conduction. Alternatively, in some other embodiments, the locking member 113 can also isolate the heat transmission of the heating element 112 to prevent other parts of the clamping arm 11, except for the working surface 115, from getting hot and affecting the user's use.

[0096] In this embodiment, the locking member 113 is connected to the heating plate 111 by screws; specifically, the protrusion 116 is set as a hollow structure, and a screw hole 1131 is provided at the position of the corresponding part of the protrusion 116 on the locking member 113. A nut structure is provided in the protrusion 116 corresponding to the screw hole 1131. The screw passes through the screw hole 1131 and then cooperates with the nut structure to connect the locking member 113 to the heating plate 111.

[0097] Understandably, the tooth 116 is designed as a hollow structure to reduce its volume, making it easier to conduct heat and making the hair styling tool 1 lighter. It also makes it easier to set a nut structure inside the tooth 116, without the need for additional structures or means to fix the locking part 113. In addition, the tooth 116 has a certain height to ensure that the screw can be screwed in to a sufficient depth and fixed securely.

[0098] Furthermore, an insulating member 18 is provided on the side of the locking member 113 away from the heating member 112. The insulating member 18 forms an insulating space in which the heating plate 111, the heating member 112, the temperature sensing member 118, and the locking member 113 are located. Understandably, the above structures are enclosed by the insulating member 18 to isolate them from other structures in the clamping arm 11, ensuring safe use.

[0099] Furthermore, a heat insulation layer 19 is provided on the side of the insulating component 18 facing away from the heating plate. Understandably, the heat insulation layer 19 is used to insulate the heat generated by the heating component 112 and prevent heat from being transferred to the side of the clamping arm 11 facing away from the protrusion 116, thus improving the user experience. Preferably, the heat insulation layer is made of heat insulation cotton.

[0100] Please combine Figure 4 and Figure 9 The top surface 1161 of the protruding tooth 116 away from the heating plate 111 is set as a concave curved surface. After the two clamping arms 11 are clamped, the top surface 1161 of the protruding tooth 116 abuts against the heating plate 111 of the other clamping arm 11. The part on the heating plate 111 that abuts against the top surface 1161 of the protruding tooth 116 on the other clamping arm 11 is defined as the abutting part 1111, wherein the abutting part 1111 matches the shape of the top surface 1161.

[0101] Both of the clamp arms 11 have abutment portions 1111 on their ironing plates 111. Each abutment portion 1111 corresponds to a protruding tooth 116 on the other ironing plate 111. The abutment portions 1111 and the top surface 1161 fit together and are both curved surfaces. When ironing hair, this allows the curved surface of the hair to have a certain aesthetic curvature rather than a straight shape, further avoiding the drawback of creating a square head shape and achieving an aesthetic effect. More specifically, the abutment portion 1111 is also part of the structure on the ironing plate 111.

[0102] Furthermore, in this embodiment, adjacent protrusions 116 on the same clamping arm 11 are spaced apart and do not contact each other; and after the two clamping arms 11 are clamped, the protrusions 116 on the two clamping arms 11 do not contact each other, and a gap remains between adjacent protrusions 116. Understandably, the gap between adjacent protrusions 116 after the two clamping arms 11 are clamped prevents the hair from being clamped too tightly, which could cause breakage, and also allows for the simultaneous clamping of a larger number of hairs, improving the styling efficiency. More specifically, in this embodiment, the spacing between each protrusion 116 is also equal. After the two clamping arms are clamped, the gap between adjacent protrusions 116 ranges from 0.5 to 1.5 mm.

[0103] Furthermore, on at least one clamping arm 11, a negative ion emitter 12 is provided on the surface where the protruding teeth 116 are located and near the protruding teeth 116. The negative ion emitter 12 can emit negative ions toward the protruding teeth 116. Specifically, in this embodiment, a negative ion emitter 12 is provided on only one of the clamping arms 11.

[0104] Understandably, the negative ion emitter 12 emits negative ions, which coat the hair surface while the hair is being heated and styled, effectively reducing hair damage caused by the heat-setting process and making the hair smoother and shinier. In actual use, when the hair styling tool 1 is in operation, the negative ion emitter 12 also starts working simultaneously, continuously emitting negative ions towards the protruding teeth 116.

[0105] Specifically, a protruding cavity 121 is provided on the clamping arm 11 where the negative ion emitter 12 is located. The negative ion emitting end of the negative ion emitter 12 protrudes from the protruding cavity 121, thereby ensuring that negative ions can be emitted toward the position of the protruding teeth 116 when the hair styling device 1 is in working condition.

[0106] Please combine further Figure 4 and Figure 10 The hair styling device 1 provided in the first embodiment of the present invention also has a timer function. Users can set the styling time of the hairstyle through the timer function. The styling time is set according to the different hair types of users to achieve the best styling effect. If it is too long, it will cause damage to the hair. If it is too short, because the hair also has gravity, if the heating time is not enough, it will straighten again very quickly. Specifically, a switching element is provided on the clamping arm 11 for timing the shaping after the two clamping arms 11 are clamped together. Preferably, in this embodiment, the switching element includes a Hall element 15 and a magnet 16. The Hall element 15 and the magnet 16 are respectively disposed in the space of the two clamping arms 11 and close to the opposite surfaces of the two clamping arms. Specifically, the magnet 16 is disposed in the protruding cavity 121, and the Hall element 15 is disposed in the other clamping arm 11 and corresponds to the position of the protruding cavity 121. It can be understood that since the protruding cavity 121 protrudes more from this side of the clamping arm 11, the magnet 16 disposed in the protruding cavity 121 can be closer to the other clamping arm 11, so that the Hall element 15 can more accurately sense the magnet, thereby ensuring that the timing function is accurate and without the need to set an additional protruding structure to reduce the distance between the Hall element 15 and the magnet 16.

[0107] Please combine Figure 12 Furthermore, each of the two clamping arms 11 is provided with a circuit board 20, and the two circuit boards 20 are connected by signals. A Hall element 15 is provided on the circuit board 20 in the corresponding clamping arm 11. A main control unit is provided on one of the circuit boards 20, and the Hall element 15 is connected by signals to the main control unit. A vibration element 17 is also provided on one of the clamping arms 11, and the vibration element 17 is connected by signals to the main control unit.

[0108] Understandably, by providing circuit boards 20 within both clamping arms 11, each module can be mounted on one of the two circuit boards 20, rather than integrated onto a single circuit board 20. This reduces the space required for a single clamping arm 11, utilizing the space of both clamping arms 11 to make the overall shape of the hair styling device 14 more compact. The Hall element 15 can be a Hall sensor, and the vibrating element 17 can be a vibration motor; more than one vibrating element 17 can be provided.

[0109] Understandably, when the hair styling tool 1 is in use, the user can first set the styling time. After the two clamping arms 11 are clamped, the Hall element 15 and the magnet sense the signal and transmit it to the main control unit. Then the main control unit starts timing. When the user-set time is reached, the vibration element provides vibration feedback to remind the user that the set styling time has been reached. The clamping arms 11 can be released to prevent damage to the hair caused by overheating. Through the timer function, it is more convenient for users to use and operate, and the best styling effect can be achieved.

[0110] Please combine Figure 9 and Figures 13-14 Furthermore, a protrusion 114 is provided on the side of the clamp arm 11 that bends to form a recess. Understandably, during use, the protrusion 114 can maintain the distance between the scalp and the protrusion 116, preventing the scalp cells from being burned due to excessive close proximity and damaging the hair growth environment; specifically, this protrusion 114 is provided on the first side surface 117a, and the height of the protrusion 114 relative to the first side surface 117a is not less than 1mm.

[0111] Specifically, the clamping arm 11 includes a first housing 11a and a second housing 11b. At the connection between the first housing 11a and the second housing 11b, and on the side of the bent and recessed clamping arm 11, a snap-fit ​​strip 21 is snapped in place, and a protrusion 114 is provided on the snap-fit ​​strip 21.

[0112] Understandably, the space formed by the clamping arm 11 is surrounded by the first housing 11a and the second housing 11b. A snap-fit ​​block 120 is provided at the connection between the first housing 11a and the second housing 11b and on either the first housing 11a or the second housing 11b. A snap-fit ​​hole 210 is provided on the snap-fit ​​strip 21. The snap-fit ​​hole 210 cooperates with the snap-fit ​​block 210 to fix the snap-fit ​​strip 21. The snap-fit ​​strip 21 is not fixed by adhesive, as the adhesive will deform under high temperature and its durability is not high.

[0113] In addition, a groove for accommodating the snap-fit ​​strip 21 is formed at the connection between the first housing 11a and the second housing 11b, while only the protrusion 114 is kept to protrude more than the clamping arm 11 to maintain aesthetics.

[0114] Preferably, in this embodiment, the protrusions 114 are configured with smooth surfaces and are arranged in multiple, spaced apart. This ensures that during use, the protrusions of the hair styling device 1 contact the user's scalp. Because they are smooth, the contact area between the protrusions 114 and the scalp is smaller, reducing the risk of damaging scalp cells. Even if the heating plate generates heat during use, it is less likely to conduct heat and burn the user's scalp. Furthermore, the protrusions 114 are made of materials with low thermal conductivity, such as silicone, to further prevent burns to the user's scalp.

[0115] To maintain the aesthetic appeal of the hair styling tool 1, for each clamp arm 11, the projection area on the other clamp arm 11 just covers the other clamp arm 11, so that the entire hair styling tool 1 achieves a symmetrical structure. Only the protrusions 116 on the two clamp arms 11 are staggered, while the rest can be set symmetrically to maintain aesthetics.

[0116] Compared with the prior art, the comb plate and hair styling tool provided by the present invention have the following advantages:

[0117] The comb plate provided in this embodiment of the invention, due to its curved arc, allows it to better conform to the shape of the human head, more effectively clamping and styling the hair roots. This ensures that the hair is properly clamped and styled at the roots, supporting it and creating a voluminous effect that prevents it from becoming oily. Furthermore, during styling, the concave arc of the curved comb plate better matches the convex arc of the head shape. This ensures that the distance between the clamped portion and the hair roots is equal during styling, resulting in a more closely approximate convex arc shape after styling. This overcomes the drawback of straight comb plates, which cannot match the convex arc of the head and instead result in a square-shaped style after styling.

[0118] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the principles of the present invention should be included within the protection scope of the present invention.
