Abstract

A comb plate (2) and a hair styling device (1). The comb plate (2) comprises a perming plate (111) and protruding teeth (116) arranged on the perming plate (111), the protruding teeth (116) being arranged in rows, and at least one row of the protruding teeth (116) being configured in an arc shape. The side of the perming plate (111) close to the protruding teeth (116) configured in the arc shape is configured in an arc shape, the curvature thereof being matched with the curvature of the protruding teeth (116) configured in the arc shape. Due to the arc shape configuration of the perming plate (111), the protruding teeth (116) thereon can better fit the shape of a human head, and better clamp-perm hair roots. During perming, the concave arc-shaped contour of the arc-shaped comb plate (2) can be better matched with the convex arc shape of the head, so that during clamp-perming, the distances from clamp-permed hair parts to the hair roots are equal to each other. As a result, the overall shape of the clamp-permed hair more closely resembles the convex arc-shaped contour of the head, thus solving the defect that a straight splint fails to be matched with the convex arc shape of the head during clamp-perming and thus leads to the entire clamp-permed shape becoming square.

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

Referring to Fig. 2-Fig. 3, the first embodiment of the present invention provides a comb plate 2, which includes an ironing plate 111 and convex teeth 116 arranged on the ironing plate 111, wherein the convex teeth 116 are arranged in rows, wherein at least one row of convex teeth 116 is arranged in an arc shape, and a side of the ironing plate 111 close to the convex teeth 116 arranged in an arc shape, and the arc matches the arc of the convex teeth 116 arranged in an arc shape.

It can be understood that the row of arc-shaped convex teeth 116 is the outermost row, and the side of the ironing plate 111 close to the row of arc-shaped convex teeth 116 is arc-shaped, which can better match the arc shape of the human head, so that the row of arc-shaped convex teeth 116 can clamp the roots of the hair.

In a specific embodiment, each row of convex teeth 116 is arranged in an arc shape, and the curvature of each row of convex teeth 116 is equal.

The ironing board 111 includes a first side 111a and a second side 111b which are arranged opposite to each other, and the protruding teeth are arranged in a row along the extension direction of the first side 111a, and the first side 111a and the second side 111b are adjacent to each other to form a protruding surface of the ironing board, wherein the first side 111a and the second side 111b are both arranged in an arc shape. Each row of protruding teeth 116 is in an arc shape and adjacent protruding teeth 116 are arranged at intervals.

It can be understood that when in use, due to the curvature of the comb tooth plate 2, the comb tooth plate 2 can better fit the shape of the human head, better curl the roots of the hair, so that the hair can be curled and shaped at the roots, and the roots support the hair. Since the roots support the hair after curling, the hair is fluffy and not easy to be greasy. In addition, when curling, the concave arc profile of the arc comb tooth plate 2 can better match the convex arc of the head shape, so that when curling, the curled part of the hair is at an equal distance from the root of the hair, and the overall head shape after curling can be closer to the convex arc profile of the head shape, which solves the problem that the straight clamp cannot match the convex arc of the head shape during curling, but instead causes the entire shape to become square after curling.

Furthermore, the first side 111a is defined as the concave side of the ironing plate 111, and the length of the long side of the protruding tooth 116 close to the first side 111a is shorter than the length of the long side close to the second side 111b.

It can be understood that, as shown in FIG. 2 , the length of the long side of the protruding tooth 116 close to the first side 111a is N, and the length of the long side close to the second side 111b is M. Since the ironing board 111 is bent, the length of the first side 111a is The protruding teeth 116 need to adapt to such a curved structure. Therefore, when the protruding teeth 116 are arranged, M is greater than N. There is no need to add additional protruding teeth 116 on the outside to utilize the outside space and arrange them reasonably.

Furthermore, the protruding teeth 116 in the same row are equidistant from the first side 111a or the second side 111b. It can be understood that the advantage of such a setting is that when the user is styling the hair, the regular arrangement of the protruding teeth 116 can ensure that the hair texture is regular and beautiful, rather than messy.

In this embodiment, the curvature of the first side 111a and the second side 111b are equal, so that the spacing distance between the two opposite sides at any position is equal. The convex teeth 116 are better arranged so that when in use, the parts of the clamped hair to be curled are all the same length, so that the hair has the same degree of fluffiness and a better aesthetic effect.

Furthermore, the convex teeth are configured as a hollow structure, wherein the convex teeth 116 are configured as a hollow structure, which reduces the volume of the convex teeth 116, makes it easier to conduct heat, and is also lighter.

Furthermore, the top surface 1161 of the convex teeth 116 away from the ironing plate 111 is set as a concave curved surface. Compared with a flat surface or a convex surface, the hair is not easy to slide to the side on the concave curved surface, which can be better styled.

Furthermore, the side surface is defined as the side surface adjacent to the top surface 1161 on the protruding teeth 116, the junction between the top surface 1161 and the side surface is set as a rounded surface, and the junction between two adjacent side surfaces is also set as a rounded surface. The edges of the protruding teeth are all set as rounded surfaces to prevent cutting and damaging the hair during use.

Referring to FIGS. 4 to 6 , a second embodiment of the present invention further provides a hairdressing device 1, comprising two clamping arms 11 and a comb plate 2 as described in the first embodiment, which is arranged on one or both of the clamping arms and on the clamping arms 11, wherein the side surfaces of the clamping arms 11 close to the arc-shaped convex teeth are arc-shaped.

Furthermore, the curvature of the curved side surface 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 ironing plate 111 cooperate with each other to conform to the curved contour of the human scalp.

One end of the two clamping arms 11 is rotatably connected, and the other end can be clamped together. The comb plate 2 is arranged on the opposite surfaces of the ends of the two clamping arms that can be clamped together.

Specifically, after the two clamping arms 11 are clamped together, the protruding teeth 116 on the two clamping arms 11 are staggered with each other; the side surface is defined as the adjacent and perpendicular to the working surface 115, and one end of the two clamping arms 11 with the protruding teeth 116 is bent toward the same side surface to form an arc-shaped clamping arm 11.

It can be understood that when in use, the heatable convex teeth 116 on the two clamping arms 11 fit together to clamp the hair and curl the hair. The hair is shaped into an undulating fluffy shape while being heated. When in use, due to the curvature of the clamping arms 11, the clamping arms 11 can better fit the shape of the human head and curl the roots of the hair better, so that the hair can be clamped and curled at the roots, and the roots support the hair. Since the roots support the hair after being clamped and curled, a fluffy effect is achieved, so it is not easy to be greasy.

Since the clip arm 11 is arranged in a curved arc shape, when curling the hair, the concave arc profile of the arc clip arm 11 can better match the convex arc profile of the head shape, so that when curling the hair, the distance between the curling part and the root of the hair is shortened. Likewise, the overall head shape after curling is closer to the convex arc contour of the head shape, which solves the problem that the straight splint cannot match the convex arc of the head shape during curling, but instead causes the entire shape to become square after curling.

It can be understood that a comb plate 2 is provided on the working surface 115 of the two clamping arms 11. In other embodiments, the size of each convex tooth 116 can also be equal for easy arrangement. In the present embodiment, the working surface 115 is a plane, and the height of each convex tooth 116 relative to the working surface 115 is equal. After clamping, the convex teeth 116 are staggered with each other, that is, it can be understood that the convex teeth 116 on one of the clamping arms 11 enter the gap between the convex teeth 116 on the other clamping arm 11, thereby clamping and curling the hair to make the hair fluffy.

Specifically, in the present embodiment, the hairdressing device 1 further comprises a hinge 13, and the two clamping arms 11 are rotatably connected via the hinge 13; 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 of the clamping arms 11 is fixedly connected to the hinge 13, and the other clamping arm 11 is rotatably connected to the hinge 13, so that the other ends of the two clamping arms 11 can be clamped together; in some other embodiments, a locking structure is further provided on the hinge 13 or on one of the clamping arms 11, for controlling the opening and closing of the two clamping arms 11, and 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.

Please combine Figures 5 and 11 to further define the clamping arm 11 rotatably connected to the hinge 13 as a movable clamping arm. The hinge 13 includes a supporting portion 131, and the supporting portion 131 is located between the two clamping arms 11. A limiting groove 1311 is formed on one side of the supporting portion 131 corresponding to the movable clamping arm. A limiting portion 119 is also provided at a position corresponding to the limiting groove 1311 on the movable clamping arm. When the two clamping arms 11 are clamped together, the movable clamping arm abuts the supporting portion 131, and the limiting portion 119 is located in the limiting groove 1311 and abuts against the inner wall of the limiting groove 1311.

It can be understood that the support portion 131 can be used to support the clamp arm 11 to prevent the front end of the clamp arm 11 on which the protruding tooth 116 is provided from swinging out of position. When the two clamp 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 clamp arm 11 from swinging in any direction other than the opening and closing direction.

Furthermore, an elastic member 1312 is further provided in the limiting groove 1311 , one end of the elastic member 1312 abuts against the groove bottom of the limiting groove 1311 , and the other end abuts against the movable clamping arm.

It can be understood that the elastic member 1312 is used to support the opening of the two clamping arms 11, that is, when the user uses the hairdressing device 1 to curl hair, the user applies a force to put the two clamping arms 11 in a closed state. After use, the user releases the force applied to the clamping arms 11, and the clamping arms 11 return to the open state due to the elastic force of the elastic member 1312.

Furthermore, the hairdressing device 1 further comprises a wire tail 14 rotatably connected to the hinge 13. It can be understood that the wire tail 14 is the end of a power cord (not shown) and is used to connect an external power source to provide working power to the hairdressing device 1; wherein the wire tail 14 is rotatable to facilitate the actual use of the hairdressing device 1.

In some other embodiments, one end of the two clamping arms 11 may be directly movably connected together to achieve a movable connection.

Please continue to refer to FIG. 5 , in which A is a schematic diagram of the state when the two clamping arms 11 on the hairdressing device 1 are clamped together, at which time the two clamping arms 11 are parallel to each other, so the working surfaces 115 thereof are parallel to each other, and the convex teeth 116 on the two clamping arms 11 are staggered with each other; FIG. 5 B is a schematic diagram of the state when the two clamping arms 11 on the hairdressing device 1 are opened, wherein there is a certain angle α between the two clamping arms 11, wherein when the hairdressing device 1 is in use, the angle α can reach a maximum of 15°, so the range of the angle α is 0°-15°, and the distance between the convex teeth closest to each other on the two clamping arms is 0-30 mm.

5-8 , further, the arc-shaped clamp arm forms two opposite sides of the bend, and the bending curvature of the two sides is equal; the clamp arm is bent to form two opposite side surfaces with a certain degree of curvature, as shown in FIG. 7 , the two opposite side surfaces are respectively named as the first side surface 117 a and the second side surface 117 b , wherein the first side surface 117 a is a concave surface relative to the entire clamp arm 11 , and the second side surface 117 b is a convex surface relative to the entire clamp arm 11 , and in this embodiment, the bending curvatures of the two side surfaces are equal.

It can be understood that the curvature of the two side surfaces can be equal, so the curved portion of the clamp arm can be regarded as a part of a circular ring, so that the spacing distance between the two opposite sides at any position is equal, and the convex teeth 116 are better arranged to achieve that when in use, the parts of the hair that can be clamped and curled by the hairdressing device 1 are of the same length, so that the hair has the same degree of fluffiness and a better aesthetic effect.

Further, as shown in the schematic diagram of human head shape in a of FIG8 , the top shape of most human heads is close to a sphere with a diameter of D=140-160 mm. Combined with b of FIG8 , in actual situations, the curvature of different positions of hair growing on a person's head is very different. For example, the position closer to the ear is flatter, and the position closer to a circle with a larger radius has a smaller curvature. Therefore, the contours of various positions of the human head shape are combined to fit a circle with a radius range of 70 mm-300 mm. Therefore, according to the adaptation of the hairdressing device 1 to different head shapes, the average curvature range of the bend is 1/0.3-1/0.07, that is, the curvature range of the arc-shaped side of the clamp arm is 1/0.3-1/0.07; and for the curved position on the clamp arm 11, the curvature of each point can be set to be different.

The curvature range of the first side 111a and the second side 111b of the comb plate 2 can match the bending curvature of the clamp arm, and the value is 1/0.3-1/0.07.

In order to facilitate use by different groups of people, it can be a small hairdressing device or a larger hairdressing device, which is more convenient to carry or convenient for users to use and can curl more hair at one time.

Therefore, the curvature of the clamp arm 11 in the present invention is more in line with the human head shape, so that it can fit the scalp better during use, and it is convenient to curl the roots of the hair to make it fluffy, and the bending direction is to bend toward the side adjacent to and perpendicular to the working surface 115. In this way, during use, the first side surface 117a with a curvature is bent to fit the scalp, and then the roots of the hair are clamped to make them perpendicular to the scalp, and then the ironing board 111 is used to curl the hair. Curl your hair to create volume.

Furthermore, a space is formed inside the clamp arm 11, the working surface 115 is provided with an opening 1151, the ironing plate 111 is located in the space and the ironing plate 111 closes the opening 1151, and the protruding teeth 116 are exposed outside the space. In this way, the comb plate 2 can be fixed more firmly.

A heating element 112 is also provided in the space. The heating element 112 is located on the back side of the ironing plate 111 away from the protruding teeth 116 . The heating element 112 is used to heat the ironing plate 111 and the protruding teeth 116 formed on the ironing plate 111 .

The ironing plate 111 and the convex teeth 116 are made of high-temperature resistant and highly conductive materials with excellent thermal conductivity, such as aluminum alloy die-castings, etc. The ironing plate 11 is a working component on the clamping arm 11 for clamping and curling hair, and the heating element 112 is used to control the heating of the ironing plate 111 and the convex teeth 116. In an actual hair styling device 1 product, the hair styling device 1 has a switch that can simultaneously control the working temperature of the heating elements 112 on the two clamping arms 11, which is convenient for users to use.

The heating element 112 is closely attached to the ironing plate 111 to provide the ironing plate 111 with the heat required for styling. When the two clamping arms 11 are attached, the convex teeth 116 of the ironing plate 111 on the upper and lower clamping arms 11 fit together, and the hair is clamped and heated between the mutually fitting working surfaces 115, so that the hair being clamped and ironed has the same shape as the convex teeth 116.

It can be understood that the shape of the ironing plate 111 can be set to conform to the curved shape of the clamping arm 11, and can also be set to a curved shape. In this embodiment, the side of the ironing plate 111 with the convex teeth 116 is arc-shaped, so that the overall head shape after curling the hair can be more similar to the convex arc contour of the head, achieving an aesthetic effect.

Combined with FIG. 4 , in other embodiments, a temperature indicator light (not shown) may be provided on the hairdressing device 1, specifically, it may be provided on one of the clamping arms 11, to remind the user of the temperature reached by the ironing plate 111 during use. Specifically, the temperature indicator light may remind the user of the current temperature of the ironing plate 111 by displaying lights of different colors. In some other embodiments, the hairdressing device 1 also has a temperature control function, and a temperature control switch 110 is provided on one of the clamping arms 11 to facilitate the user to control the perming temperature. Preferably, the temperature indicator light (not shown) may be provided on the same clamping arm 11 as the temperature control switch 110, and located on the same surface of the clamping arm 11, so that the user can conveniently check the currently selected working temperature when adjusting and selecting the working temperature of the hairdressing device 1.

When the heating element 112 is working, the heating element 112 generates heat, and then conducts the heat to the ironing plate 111 and the convex teeth 116, so as to perform a perm treatment on the hair. Specifically, in this embodiment, at least one temperature sensing element 118 is further arranged in the space, and the temperature sensing element 118 is attached to the ironing plate 111 to sense temperature changes. Specifically, the heating element 112 is a PTC heating element, and the temperature sensing element 118 is an NTC thermistor.

In this embodiment, the hairdressing device 1 is provided with three adjustable working temperatures, including 160°, 180° and 200°. When using the hairdressing device 1, the user uses the temperature control switch 110 to set the required working temperature. When the hairdressing device 1 starts to heat, the temperature sensing element 118 senses the temperature of the ironing plate 111. When sensing that the ironing plate 111 reaches the temperature preset by the user, the heating element 112 stops increasing the temperature of the ironing plate 111 and keeps the temperature of the ironing plate 111 at the set temperature.

Please refer to Figures 6 and 12-13. Specifically, in this embodiment, the space in the clamp arm 11 also includes a locking member 113, which is located on the side of the heating member 112 away from the ironing plate 111, and the locking member 113 is detachably connected to the ironing plate 111. The locking member 113 is used to firmly fix the heating member 112 against the ironing plate 111 to facilitate heat conduction, or in some other embodiments, the locking member 113 can also isolate the heat transfer of the heating member 112 to prevent other parts of the clamp arm 11 other than the working surface 115 from getting hot and affecting user use.

In this embodiment, the locking piece 113 is connected to the ironing plate 111 by means of screws; specifically, the protruding teeth 116 are configured as a hollow structure, and screw holes 1131 are provided at positions corresponding to the protruding teeth 116 on the locking piece 113, and a nut structure is provided in the protruding teeth 116 corresponding to the screw holes 1131. After the screw passes through the screw holes 1131, it cooperates with the nut structure to connect the locking piece 113 to the ironing plate 111.

It can be understood that the convex teeth 116 are configured as a hollow structure, which reduces the volume of the convex teeth 116, makes it easier to conduct heat, and also makes the hairdressing device 1 lighter. It is also convenient to set a nut structure inside the convex teeth 116, without using additional structures or means to fix the locking member 113. The convex teeth 116 have a certain height to ensure that the screw is screwed in to a sufficient depth and fixed firmly enough.

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, and the ironing plate 111, the heating member 112, the temperature sensing member 118 and the locking member 113 are located in the insulating space. It can be understood that the above structures are wrapped by the insulating member 18 to isolate the above structures from other structures in the clamp arm 11 to ensure safety in use.

Furthermore, the side of the insulating member 18 away from the ironing board is also provided with an insulation layer 19. It can be understood that the insulation layer 19 is used to isolate the heat generated by the heating element 112 and prevent the heat from being transferred to the side of the clamping arm 11 away from the convex teeth 116, so that the user experience is better. Preferably, the insulation layer is made of insulation cotton.

Please refer to Figure 4 and Figure 9, the top surface 1161 of the convex tooth 116 away from the ironing plate 111 is set as a concave curved surface. After the two clamping arms 11 are clamped, the top surface 1161 of the convex tooth 116 abuts against the ironing plate 111 of the other clamping arm 11, and the part of the ironing plate 111 abutting against the top surface 1161 of the convex tooth 116 on the other clamping arm 11 is defined as the abutting portion 1111, wherein the abutting portion 1111 and the top surface 1161 match in shape.

The ironing plates 111 of the two clamping arms 11 are both provided with abutting portions 1111, and each abutting portion 1111 corresponds to a convex tooth 116 on the other ironing plate 111. The abutting portions 1111 and the top surface 1161 fit together and are both curved surfaces, so that when curling the hair, the bent surface of the hair can have a certain aesthetically pleasing curvature instead of a straight shape, further avoiding the disadvantage of a square head shape and achieving an aesthetically pleasing effect; more specifically, the abutting portions 1111 are also part of the structure on the ironing plate 111.

Furthermore, in this embodiment, adjacent protruding teeth 116 arranged on the same clamping arm 11 are arranged at intervals and do not contact each other; and after the two clamping arms 11 are clamped together, the protruding teeth 116 on the two clamping arms 11 do not contact each other, and there is still a gap between adjacent protruding teeth 116. It can be understood that after the two clamping arms 11 are clamped together, there is still a gap between adjacent protruding teeth 116 to avoid hair breakage caused by clamping the hair too tightly, and at the same time, it is convenient to clamp and curl more hair at the same time, thereby improving the hair styling efficiency. More specifically, in this embodiment, the spacing between each protruding tooth 116 is also equal. After the two clamping arms are clamped together, the gap distance between adjacent protruding teeth 116 ranges from 0.5 to 1.5 mm.

Furthermore, on at least one clamp arm 11, a negative ion emitter 12 is provided on a surface where the protruding tooth 116 is provided and close to the protruding tooth 116, and the negative ion emitter 12 can emit negative ions toward the protruding tooth 116. Specifically, in this embodiment, the negative ion emitter 12 is provided on only one of the clamp arms 11.

It can be understood that the negative ion emitter 12 emits negative ions, and when the hair is heated and set, the negative ions will cover the surface of the hair, which can effectively reduce the hair damage caused by heating and setting, and make the hair smoother and more shiny. In actual use, when the hairdressing device 1 is in working state, the negative ion emitter 12 also starts to work synchronously, and continuously emits negative ions toward the position of the convex teeth 116.

Specifically, a protruding cavity 121 is also provided on the clamping arm 11 where the negative ion emitter 12 is provided, and the negative ion emitting end of the negative ion emitter 12 is exposed from the protruding cavity 121, thereby ensuring that negative ions can be emitted toward the position of the protruding teeth 116 when the hairdressing device 1 is in working state.

Please further refer to Figures 4 and 10. The hairdressing device 1 provided in the first embodiment of the present invention also has a timing function. The user can set the styling time of the hairstyle through the timing function. The styling time is set according to the different hair qualities of the user 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 soon become straight again. Specifically, a switch element is provided on the clamping arm 11 for performing a fixed timing after the two clamping arms 11 are clamped together. Preferably, in this embodiment, the switch element includes a Hall element 15 and a magnet 16. The Hall element 15 and the magnet 16 are respectively arranged in the space between the two clamping arms 11 and close to the opposite surfaces of the two clamping arms. Specifically, the magnet 16 is arranged in the protruding cavity 121, and the Hall element 15 is arranged 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 is more protruding relative to this side of the clamping arm 11, the magnet 16 arranged in the protruding cavity 121 can be closer to the other clamping arm 11, so that the Hall element 15 can sense the magnet more accurately, thereby ensuring that the timing function is accurate and there is no need to set an additional protruding structure to reduce the distance between the Hall element 15 and the magnet 16.

Please refer to FIG. 12 , further, the two clamping arms 11 are provided with a circuit board 20, and the two circuit boards 20 are signal-connected, and the Hall element 15 is provided on the circuit board 20 in the corresponding clamping arm 11, and one of them A main control unit is arranged on the circuit board 20 , and the Hall element 15 is connected to the main control unit signal. A vibration element 17 is also arranged on one of the clamping arms 11 , and the vibration element 17 is connected to the main control unit signal.

It can be understood that by providing the circuit boards 20 in both clamping arms 11, each module can be provided on the two circuit boards 20 respectively, instead of being integrated on one circuit board 20, so as to reduce the space of a single clamping arm 11, utilize the space of both clamping arms 11, and make the overall appearance of the hairdressing device 14 more compact. The Hall element 15 can be a Hall sensor, the vibration element 17 can be a vibration motor, and more than one vibration element 17 can be provided.

It can be understood that when the hairdressing device 1 is used, the user can first set the styling time. When the two clamping arms 11 are clamped together, the Hall element 15 and the magnet are sensed, and the signal is transmitted to the main control unit, and then the main control unit starts timing. When the time set by the user is reached, vibration feedback is given through the vibration element to prompt the user that the set styling time has arrived, and the clamping arms 11 can be released to prevent damage to the hair caused by excessive heating. Through the timing function, it is more convenient for users to use and operate, and can achieve the best styling effect.

Please refer to Figure 9 and Figure 13-14. Further, a protrusion 114 is provided on the side of the clamp arm 11 that is bent to form a depression. It can be understood that during use, the protrusion 114 can maintain the distance between the scalp and the protruding teeth 116 to prevent the scalp cells from being burned due to the close distance and destroying the growth environment of the hair. Specifically, the 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 1 mm.

Specifically, the clamp arm 11 includes a first shell 11a and a second shell 11b. A clamping strip 21 is clamped at the connection between the first shell 11a and the second shell 11b and at one side of the bent concave portion of the clamp arm 11. The protrusion 114 is disposed on the clamping strip 21.

It can be understood that the space formed by the clamping arm 11 is surrounded by the first shell 11a and the second shell 11b, and a clamping block 120 is provided at the connection between the first shell 11a and the second shell 11b and on the first shell 11a or the second shell 11b, and a clamping hole 210 is provided on the clamping strip 21. The clamping hole 210 cooperates with the clamping block 210 to fix the clamping strip 21, and the clamping strip 21 does not need to be fixed by gluing, because the glue will be deformed by high temperature and has low durability.

In addition, a groove for accommodating the clamping strip 21 is formed at the connection between the first shell 11 a and the second shell 11 b , and only the protrusion 114 is retained to be more protruding than the clamp arm 11 to maintain the appearance.

Preferably, in this embodiment, the protrusions 114 are configured to have a smooth surface, and are configured to be multiple and spaced apart. When the hairdressing device 1 is in use, the protrusions 114 contact the user's scalp. Since the protrusions 114 are configured to be smooth, the contact area between the protrusions 114 and the scalp is smaller, and it is not easy to damage the scalp cells. When the hairdressing device 1 is in use, even if the ironing plate generates heat, it is not easy to be conducted to burn the user's scalp. Secondly, the protrusions 114 are made of materials with low thermal conductivity, such as silicone, etc., to prevent the user's scalp from being burned.

In order to maintain the aesthetics of the hairdressing device 1, for each clamping arm 11, the projection area on another clamping arm 11 just covers the other clamping arm 11, so that the entire hairdressing device 1 has a symmetrical structure. Only the convex teeth 116 on the two clamping arms 11 are staggered, and the rest can be symmetrical to maintain the aesthetics.

A comb plate provided in an embodiment of the present invention can better fit the shape of the human head due to the curvature of the comb plate, and can better curl the roots of the hair, so that the hair can be curled and shaped at the roots, and the roots support the hair. Since the roots support the hair after curling, a fluffy effect is obtained, so it is not easy to be greasy. Moreover, during curling, the concave arc profile of the arc-shaped comb plate can better match the convex arc of the head shape, so that when curling, the curled part of the hair is at an equal distance from the root of the hair, and the overall head shape after curling can be closer to the convex arc profile of the head shape, which solves the problem that the straight clamping plate cannot match the convex arc of the head shape during curling, but instead causes the entire shape to become square after curling.

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 in the protection scope of the present invention.
