Description

Technical Field

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

[0002] In the modern hairdressing industry, hair straighteners are a commonly used styling tool, widely used in homes and professional hair salons due to their convenience and efficiency. Their core working principle involves using a built-in heating element (usually an aluminum plate) to generate heat, which is then used to heat and shape the hair, achieving various styling effects such as straightening and curling.

[0003] Currently, most hair styling irons on the market consist of two opposing brackets and aluminum plates (heating elements) mounted inside each bracket. During use, the brackets are closed, causing the aluminum plates to clamp the hair and transfer heat to complete the styling process. However, these irons have a significant structural design flaw: the aluminum plates, as direct heating elements, generate a large amount of heat during operation, which is transferred to the brackets. When users touch the brackets during operation, they are easily burned due to the excessively high temperature of the brackets, a safety hazard that is particularly prominent for less experienced home users. Utility Model Content

[0004] This utility model proposes a hair straightening clip to reduce heat transfer between the aluminum plate and the bracket, and to prevent the bracket from overheating and causing burns to the user.

[0005] To achieve the above objectives, the hair styling clip proposed in this utility model includes:

[0006] Two hinged clamp assemblies, the two clamp assemblies being used to clamp hair;

[0007] Each clamping plate assembly includes a support assembly, a mounting bracket, and a heating plate. The heating plate is mounted on the mounting bracket, which is connected to the support assembly and is floatable relative to the support assembly. A vent is formed between the mounting bracket and the support assembly, penetrating the clamping plate assembly. The vent extends along the length of the clamping plate assembly, with a length of L and a width of D. When the mounting bracket floats to its highest position, 0.01 ≤ D / L ≤ 0.1.

[0008] In one embodiment, when the mounting bracket floats to its lowest position, 0.015 ≦ D / L ≦ 0.07; and / or, the width of the vent decreases in the extension direction.

[0009] In one embodiment, the length of the heating plate is less than or equal to the length L of the vent.

[0010] In one embodiment, the end of the vent is provided in a pointed shape.

[0011] In one embodiment, the clamp assembly further includes an elastic element located between the support assembly and the mounting bracket, such that the mounting bracket is floatable relative to the support assembly.

[0012] In one embodiment, a limiting groove is formed at the position corresponding to the mounting bracket, and the mounting bracket can be floatably installed in the limiting groove.

[0013] In one embodiment, the mounting bracket has outwardly protruding limiting blocks at both ends, and the bracket assembly includes a housing. The housing has a first limiting part that engages with the limiting blocks, and the housing and the first limiting part form the limiting groove.

[0014] In one embodiment, there are multiple limiting grooves, with at least two limiting grooves arranged opposite to each other. The bracket assembly also includes a first cover plate and a second cover plate disposed on the outer shell. The first cover plate, the outer shell, and the first limiting part form one limiting groove.

[0015] One end of the second cover plate is provided with a second limiting part that engages with the limiting block, and the second cover plate, the outer shell, and the second limiting part form another limiting groove.

[0016] In one embodiment, the bottom wall of the limiting groove is formed with a receiving groove, and the elastic member is located in the receiving groove.

[0017] In one embodiment, the hair styling clip further includes a light-emitting component, which includes a light guide and an LED light source located on one side of the light guide. The light guide is disposed on the bracket assembly, and at least a portion of the light guide is exposed to the outside.

[0018] In one embodiment, the mounting bracket is provided with a mounting groove for placing a heating plate, the mounting groove having a first groove wall, the first groove wall being provided with a first retaining plate for inserting the heating plate; and / or,

[0019] The mounting bracket is provided with a mounting groove for placing a heating plate. The mounting groove has a second groove wall. The mounting bracket is provided with a fixing member that is fixed by a locking member. One side of the fixing member forms the second groove wall. The second groove wall is provided with a second retaining plate for inserting the heating plate.

[0020] This utility model also proposes a hair styling clip, comprising:

[0021] Two hinged clamp assemblies, the two clamp assemblies being used to clamp hair;

[0022] Each clamping plate assembly includes a support assembly, a mounting bracket, and a heating plate. The heating plate is mounted on the mounting bracket, which is connected to the support assembly and is floatable relative to the support assembly. A vent is formed between the mounting bracket and the support assembly, penetrating the clamping plate assembly.

[0023] The clamping plate assembly also includes a blocking member located at the vent, the blocking member being disposed on the bracket assembly or mounting bracket.

[0024] The technical solution of this utility model creates an air convection channel by setting a vent between the mounting bracket and the support assembly. This allows for the rapid dissipation of heat transferred from the heating plate to the connection point, significantly reducing heat conduction to the support assembly and effectively lowering its temperature. This prevents users from being burned by contact with the support during operation. Furthermore, the floating setting of the heating plate relative to the support assembly allows it to better conform to hair of different textures and volumes, avoiding pulling on the hair and improving heating uniformity, styling effect, and user experience.

[0046] Currently, common hair straighteners on the market have a significant structural design flaw: the aluminum plate, as the direct heating element, generates a large amount of heat during operation, which can be transferred to the support frame. Contact with the support frame poses a risk of burns to the user. This type of hair straightener negatively impacts the user experience.

[0047] Therefore, this utility model proposes a hair straightener to solve this problem.

[0048] Please see Figures 1 to 7 As shown, in one embodiment of this utility model, the hair straightener may include a clamp assembly 10, a control board 20, and a power cord 30. There are two clamp assemblies 10, which are arranged opposite each other and hinged together. The two clamp assemblies 10 are used to clamp hair to heat it, thereby performing operations such as straightening or curling. The control board 20 is disposed inside one of the clamp assemblies 10, and the power cord 30 is electrically connected to the control board 20.

[0049] Each clamping assembly 10 includes a support assembly 11, a mounting frame 13, and a heating plate 12. The heating plate 12 is mounted on the mounting frame 13, which is connected to the support assembly 11 and is floating relative to the support assembly 11. A vent 14 is formed between the mounting frame 13 and the support assembly 11, extending through both sides of the clamping assembly 10. Specifically, the two support assemblies 11 are arranged opposite each other and hinged to each other at the ends of the support assemblies 11. This structure allows for flexible opening and closing, enabling the heating plates 12 on the two support assemblies 11 to move relative to each other, thus clamping the hair with the heating plates 12. The control board 20 is the control core of the device and is located inside one of the clamping assemblies 10. The power cord 30 serves as the power supply connection, with one end electrically connected to the control board 20 and the other end used to connect to an external power source.

[0050] Furthermore, the heating plate 12 is mounted on the mounting bracket 13, which is floating relative to the support assembly 11. This floating capability means that the mounting bracket 13 and the heating plate 12 elastically sway synchronously on the support assembly 11, allowing for adaptive adjustment of the angle and distance between the two heating plates 12 on the two clamping plate assemblies 10. A vent 14 is formed between the mounting bracket 13 and the support assembly 11, penetrating both sides of the clamping plate assembly 10.

[0051] In terms of connection, the two clamping plate assemblies 10 are linked by a hinge to form the main structure for clamping hair. A control board 20 is integrated inside one of the clamping plate assemblies 10. A power cord 30 acts as a bridge, with one end extending into the clamping plate assembly 10 and electrically connected to the control board 20, and the other end having a plug to receive external AC power and provide power to the entire device. Alternatively, the hair styling clamp can have a built-in power supply component, electrically connected to the heating plate 12 of the clamping plate assembly 10 via the control board 20.

[0052] For a single clamping plate assembly 10, the support assembly 11 is the basic load-bearing structure, the mounting bracket 13 is connected to the support assembly 11, and the heating plate 12 is mounted on the support assembly 11, allowing the mounting bracket 13 and the heating plate 12 to float relative to the support assembly 11. The connection between the support assembly 11 and the mounting bracket 13 is structurally designed to extend through both sides of the clamping plate assembly 10 in the width direction (i.e., the Y direction, see [reference]). Figure 3 Vent 14.

[0053] These designs bring about several benefits: First, the two hinged clamping plate assemblies 10 stably clamp the hair through their opening and closing action, and in conjunction with the heating function of the heating plate 12, can efficiently complete styling operations such as straightening or curling hair. Second, the floating arrangement of the heating plate 12 and the mounting bracket 13 relative to the support assembly 11 reduces the pulling on the hair. Most importantly, the vent 14 between the mounting bracket 13 and the support assembly 11 forms an air convection channel, quickly dissipating the heat transferred from the heating plate 12 to the mounting bracket 13, significantly reducing heat conduction to the support assembly 11, effectively lowering the temperature of the support assembly 11, and thus preventing users from being burned by contact with the support assembly 11 during operation. The vent design also improves heat utilization, resulting in better hair styling. Furthermore, during the curling process, the large temperature difference between the inner and outer parts of the hair facilitates rapid hair shaping.

[0054] It should be noted that the heating plate 12 can be an aluminum sheet metal part, and a heating module (not shown in the figure) is also provided inside the heating plate 12. The heating module is electrically connected to the control board 20 and is used to heat the heating plate 12.

[0055] Furthermore, the vent 14 is elongated and extends along the length of the clamp assembly 10.

[0056] Please see Figures 2 to 3 In this embodiment, an elongated vent 14 is formed between the mounting bracket 13 and the support assembly 11. The vent 14 extends along the length (X direction) of the clamping plate assembly 10 and penetrates the width (Y direction) of the clamping plate assembly, meaning that the air convection direction is along the Y direction. The elongated vent 14 design increases the cross-sectional area of ​​airflow, improves air convection efficiency, and more quickly removes the heat transferred from the heating plate 12 to the mounting bracket 13. The opening of the vent 14 is located in the width direction of the clamping plate assembly 10, which conforms to the airflow direction during daily use, reduces airflow resistance, further enhances the heat dissipation effect, and thus more effectively reduces the temperature of the support assembly 11, reducing the risk of burns to users. It also helps maintain the stable operating temperature of the heating plate 12 and improves equipment performance.

[0057] Please continue reading. Figure 2 In one embodiment, the length of the vent 14 is L and the width is D. When the mounting bracket 13 floats to the highest position, 0.01≦D / L≦0.1.

[0058] Specifically, in this embodiment, the cross-sectional length L of the vent 14 is the length of the vent 14 along the length direction (X direction) of the clamping plate assembly 10, and the width D is the length of the clamping plate assembly 10 in the thickness direction (Z direction). Wherein, as... Figure 2As shown, the starting point of L is the junction of the bracket assembly 11 and the mounting bracket 13 in the X direction; the ending point of L is the junction of the bracket assembly 11 and the mounting bracket 13 in the X direction. That is, the length L of the vent 14 is the distance between the two longest points in the X direction. The vent 14 is approximately parallel in the width direction, and D is the farthest distance between the mounting bracket 13 and the bracket assembly 11 in the Z direction.

[0059] In this embodiment, the aspect ratio of the vent 14 is designed so that its cross-section is a long and narrow strip. When the mounting bracket 13 floats to its highest position, i.e., in its initial unloaded state, D and L satisfy the ratio setting of 0.01≦D / L≦0.1. This ensures that the vent 14 has sufficient length to cover the main heating area of ​​the heating plate 12 while balancing the space occupancy rate and adapting to the compact structure of the clamping plate. This ratio range balances heat dissipation performance and space occupancy rate, enabling the vent 14 to effectively dissipate heat, reduce the temperature of the bracket assembly 11, and ensure the portability of the equipment.

[0060] When D / L < 0.01, the effective flow area of ​​the vent 14 is significantly reduced, resulting in low airflow heat dissipation efficiency. Unexhausted heat will be conducted outwards through the mounting bracket 13, causing the outer surface temperature of the bracket assembly 11 to rise to 110.9℃, posing a risk of burns. Furthermore, the narrow vent 14 also leads to the accumulation of debris such as hair and dust, requiring frequent and timely cleaning by the user, causing considerable inconvenience.

[0061] When D / L > 0.1, the width D of the vent 14 increases significantly. If the space for internal components is not compressed, the width of the entire device needs to be increased. The original 10mm width of the bracket assembly 11 may need to be increased to over 12mm, causing the width of a single clamp assembly 10 to increase from 30mm to over 35mm, violating the design requirements of the Meifa clamp for a slim and portable design. Forcibly compressing the space for internal components also leads to a crowded structural layout, making component interference more likely during assembly, and significantly increasing the difficulty of disassembly during later maintenance, thus increasing maintenance costs. Furthermore, when the vent width is too large, the airflow entering the vent cannot form a stable laminar flow; instead, diffuse turbulence occurs, and the heat dissipation effect is not improved.

[0062] The table below shows the shell surface temperature data for different ratios of D to L when L = 100 mm.

[0063]

[0064]

[0065] Furthermore, when the mounting bracket 13 floats to its lowest position, 0.015≦D / L≦0.07.

[0066] Specifically, in this embodiment, when the mounting bracket 13 floats to its lowest position, the distance between the two mounting brackets 13 is at its farthest, yet the vent 14 still exists, and at this time, 0.015≦D / L≦0.07. This design ensures that the heat dissipation channel is not completely blocked when the heating plate 12 is closest to the support assembly 11, continuously ensuring airflow and preventing heat accumulation under this condition. At this time, D and L satisfy the ratio setting of 0.015≦D / L≦0.07, ensuring that the vent 14 still has a certain heat dissipation capacity to effectively dissipate heat, while the relatively reduced width adapts to the space constraints when the mounting bracket 13 is at its lowest position, avoiding interference with other components. Simultaneously, it maintains the stability of the connection structure between the mounting bracket 13 and the support assembly 11, further improving the safety and reliability of the equipment under different operating conditions.

[0067] Please see Figure 2 In one embodiment, the width of the vent 14 decreases in the extending direction. The decreasing width shape can naturally guide the airflow, directing the airflow smoothly from the main body of the vent 14 to the end, reducing airflow stagnation and eddy currents at the end, improving airflow efficiency, thereby enhancing heat dissipation, more efficiently removing the heat generated by the heating components, and reducing the internal temperature of the equipment.

[0068] Furthermore, in one embodiment, the end of the vent 14 is provided in an angled shape.

[0069] Specifically, the width of both ends of the vent 14 along its length is reduced, forming a pointed shape. On the one hand, while ensuring that the main body of the vent 14 has sufficient flow area to meet heat dissipation requirements, it reduces the impact of the vent 14 on the structural strength of the connection between the mounting bracket 13 and the support assembly 11, avoiding stress concentration at the connection due to excessive width at the ends, and enhancing the overall structural stability. On the other hand, the pointed shape helps guide airflow more smoothly into and out of the vent 14, reducing airflow eddies at the ends, improving airflow efficiency, ensuring uniform heat dissipation, further reducing the temperature of the support assembly 11, and improving the safety of equipment use. In addition, this design also makes the shape of the vent 14 more in line with the internal spatial layout of the equipment, improving the compactness of the structure.

[0070] Please continue reading. Figure 2 In one embodiment, the length of the heating plate 12 is less than or equal to the length L of the vent 14.

[0071] Specifically, the heating plate 12 is installed on the side of the mounting bracket 13 opposite to the vent 14, which is formed between the mounting bracket 13 and the support assembly 11. The length of the heating plate 12 is less than or equal to the length of the vent 14, ensuring that the heat dissipation range of the vent 14 completely covers the main heat-generating area of ​​the heating plate 12. This allows the heat generated by the heating plate 12 during operation to be dissipated more comprehensively and efficiently through the vent 14, avoiding localized heat accumulation due to insufficient heat dissipation range. This design further optimizes heat dissipation efficiency, more effectively preventing heat transfer to the support assembly 11, reducing the temperature of the support assembly 11, and continuously ensuring user safety. At the same time, this size matching relationship also makes the internal structural layout of the equipment more reasonable, avoiding heat dissipation dead zones caused by size mismatch, and improving the overall thermal management performance of the equipment.

[0072] Please see Figure 5 , Figure 6 and Figure 12 In one embodiment, the clamp assembly 10 further includes an elastic element 15 located between the bracket assembly 11 and the mounting bracket 13, such that the mounting bracket 13 is floatable relative to the bracket assembly 11.

[0073] Specifically, in this embodiment, there can be two elastic elements 15, with each elastic element 15 located at one end of the mounting frame 13 along its length, and between the support assembly 11 and the mounting frame 13. One end of each elastic element 15 abuts against the mounting frame 13, and the other end of each elastic element 15 abuts against the support assembly 11. The two elastic elements 15 together provide support for the floating of the mounting frame 13 relative to the support assembly 11. It is understood that the elastic element can be a spring.

[0074] Two elastic elements 15 are spaced apart on the central axis of the mounting frame 13, which makes the mounting frame 13 more evenly and stably stressed when floating, avoiding tilting or swaying of the mounting frame 13 that may be caused by single-point support. This further ensures the uniformity of contact between the mounting frame 13 and the hair, improves the stability and consistency of the styling, and also enhances the reliability and service life of the entire hair straightener assembly 10. At the same time, the heating plate 12 can deflect along the central axis of the mounting frame 13, which is beneficial for hair styling and avoids pulling the hair.

[0075] It should be noted that the number of elastic elements 15 can also be increased, and the specific number is not limited here. In some embodiments, the number of elastic elements 15 can be set to 4, with 2 elastic elements at each end of the mounting bracket, and the two elastic elements at the same end are spaced apart, thereby making the heating plate 12 more stable.

[0076] Please see Figure 5 , Figure 6 and Figure 10In one embodiment, the bracket assembly 11 is provided with a limiting groove 113, and the mounting bracket 13 is floatably mounted in the limiting groove 113.

[0077] Specifically, in this embodiment, the limiting groove 113 cooperates with both ends of the mounting frame 13 to form a guide structure for the mounting frame 13 to float relative to the support assembly 11, allowing the mounting frame 13 to slide stably along the limiting groove 113. The limiting groove 113, in conjunction with the support assembly 11, guides and limits the sliding of the mounting frame 13, ensuring that the mounting frame 13 does not deviate from the preset trajectory during floating, thus guaranteeing the accuracy of the contact between the heating plate 12 and the hair, thereby improving the styling effect. At the same time, it makes the floating of the heating plate 12 and the mounting frame 13 more stable, reducing shaking and enhancing the overall structural stability and service life of the equipment.

[0078] The limiting groove 113 has various structures; please refer to [link / reference]. Figure 6 , Figure 11 and Figure 12 In one embodiment, the mounting bracket 13 has limiting blocks 135 protruding outward at both ends, and the bracket assembly 11 includes a housing 111. The housing 111 has a first limiting part 114 that engages with the limiting block 135, and the housing 111 and the first limiting part 114 form a limiting groove 113.

[0079] Specifically, in this embodiment, the limiting groove 113 on the bracket assembly 11 is adapted to both ends of the mounting bracket 13. The outer shell 111 is provided with a first limiting part 114, and the limiting groove 113 is formed between the outer shell 1111 and the first limiting part 114. The first limiting part 114 is used to block the limiting block 135 to limit the farthest floating position of the limiting block 135. When the mounting bracket 13 moves within the limiting groove 113, the limiting block 135 moves synchronously in the same direction. When the limiting block 135 moves to the farthest position, it abuts against the first limiting part 114, thereby ensuring that the mounting bracket 13 will not detach from the bracket assembly 11 while floating.

[0080] Please refer to Figures 10 to 13 In one embodiment, the bracket assembly 11 is provided with a plurality of limiting grooves 113, at least two limiting grooves 113 being arranged opposite to each other. The bracket assembly 11 also includes a first cover plate 116 and a second cover plate 112 disposed on the outer shell 111. The first cover plate 116, the outer shell 111 and the first limiting part 114 form one of the limiting grooves 113. One end of the second cover plate 112 is provided with a second limiting part 117 that engages with the limiting block 135. The second cover plate 112, the outer shell 111 and the second limiting part 117 form another limiting groove 113.

[0081] The outer shell 111 is a structural component with an internal cavity. It serves as the basic load-bearing component of the support assembly 11, providing a spatial basis for the assembly of the second cover plate 112 and the first cover plate 116. Together with the second cover plate 112 and the first cover plate 116, it forms the overall frame of the support assembly 11. The second cover plate 112 and the first cover plate 116 are installed at the opening of the cavity to partially enclose it. Please refer to... Figures 6 to 7 , Figures 10 to 13 At least two limiting grooves 113 are arranged opposite to each other. One of the limiting grooves 113 is formed between the first cover plate 116, the outer shell 111 and the first limiting part 114. A second limiting part 117 is provided at one end of the second cover 112 near the first cover plate 116. The second limiting part 117 is fastened to another limiting block 135 of the mounting bracket 13. Another limiting groove is formed between the second cover plate 112, the outer shell 111 and the second limiting part 117.

[0082] In this embodiment, the limiting groove 113 is not formed independently as a single component, but rather is formed through the coordinated cooperation of the first cover plate 116, the second cover plate 113, and the outer shell 111. The two limiting grooves 113 are located on opposite sides of the length of the first cover plate 116, corresponding to both ends of the mounting bracket 13, thus providing bidirectional guidance for the sliding of the mounting bracket 13 and ensuring the stability of the floating motion of the heating plate 12. In this embodiment, the limiting groove 113 is formed by assembling the first cover plate 116, the second cover plate 112, and the outer shell 111, making full use of the existing structural space, resulting in a more compact internal layout of the support assembly 11 and reducing the space occupied by redundant structures.

[0083] Please refer to Figures 5 to 7 , Figure 12 In one embodiment, a receiving groove 115 is formed on the bottom wall of the limiting groove 113, and the elastic member 15 is located in the receiving groove 115.

[0084] Specifically, the bottom wall of the limiting groove 113 is recessed towards the side away from the mounting bracket 13 to form a receiving groove 115, and the receiving groove 115 and the limiting groove 113 form a stepped shape, thereby providing space for the elastic member 15. The elastic member 15 serves as an intermediate component connecting the mounting bracket 13 and the bracket assembly 11, and its two ends respectively form an abutment relationship with the movable end 134 of the mounting bracket 13 and the bottom wall of the receiving groove 115.

[0085] As the movable end 134 of the mounting bracket 13 moves, the elastic element 15 is compressed and reset within the limiting groove 113. Simultaneously, the stepped structure of the receiving groove 115 further limits the extension and retraction direction of the elastic element 15, preventing it from shifting. (For illustrative purposes, please refer to...) Figures 10 to 12The receiving groove 115 is provided on the first cover plate 116, and the elastic member 15 can pass through the first cover plate 116, with one end abutting against the inner side of the outer shell 111 and the other end abutting against the mounting bracket 13. It should be noted that in some embodiments, the elastic member 15 can also be limited by a limiting post, for example, a limiting post is provided at one movable end 134 of the mounting bracket 13, and the elastic member 15 is sleeved in the limiting post.

[0086] Please refer to Figure 8 and Figure 9 Furthermore, the mounting bracket 13 is provided with a mounting groove 131, and the heating plate 12 is disposed in the mounting groove 131. The mounting groove 131 has a first groove wall 1311, and the first groove wall 1311 is provided with a first retaining plate 132 for inserting the heating plate. The mounting groove 13 may also have a second groove wall 1312, and the mounting bracket is provided with a fixing member 133 fixed by a locking member. The side wall of the fixing member 133 forms the second groove wall 1312, and the second groove wall 1312 is provided with a second retaining plate 1331 for inserting the heating plate.

[0087] Specifically, in this embodiment, the mounting bracket 13 provides mounting space for the heating plate 12 through the mounting groove 131. The mounting bracket 13 can be a long strip structure, and a fixing member 133 is installed at one end of the mounting bracket 13. The fixing member 133 and the mounting bracket 13 form the mounting groove 131. The size of the mounting groove 131 is adapted to the size of the heating plate 12 to accommodate the heating plate 12.

[0088] One end of the mounting groove 131 along its length is defined as the first groove wall 1311, and the other end is defined as the second groove wall 1312 (the second groove wall 1312 is formed by the side wall of the fastener 133). The first groove wall 1311 has a protruding first retaining plate 132, which is inserted into one end of the heating plate 12. The second groove wall 1312 has a protruding second retaining plate 1331, which is also inserted into the heating plate 12, thus forming a stable connection between the heating plate 12 and the mounting bracket 13. This ensures that the heating plate 12 will not loosen or shift within the mounting bracket 13, thereby guaranteeing the overall stability of the heating plate 12 structure. The fastener 133 is fixedly installed at the other end of the mounting groove 131 by a locking component, which can be a screw.

[0089] The first clamping plate 132 and the second clamping plate 1331 can both be square protrusion structures, the size of which is adapted to the through opening on the heating plate 12, so that they can be inserted into the interior of the heating plate 12 from both ends to position the heating plate 12. The width of the fixing member 133 is adapted to the mounting groove 131, so that it can be placed in the mounting groove 131 to fix the end of the heating plate 12 away from the first clamping plate 132. It should be noted that the fixing member 133 can also be fixed by means of adhesive, fastening, etc.; both ends of the mounting bracket can be provided with fixing members 133.

[0090] By inserting the first clamping plate 132 into the heating plate 12 and the second clamping plate 1331 of the fixing member 133 into the heating plate 12, not only is the heating plate 12 securely installed, but it also provides a certain positioning function, ensuring the positional accuracy of the heating plate 12 during operation. The heating plate 12 can be an aluminum sheet rib. Utilizing the high strength and good formability of the rib, the structural strength of the aluminum plate can be enhanced, extending its service life. At the same time, it can better cooperate with the first clamping plate 132 and the second clamping plate 1331 to achieve a connection with the mounting frame 13, further improving the overall reliability of the mounting frame 13 and the heating plate 12. In addition, this structural design also facilitates the assembly and maintenance of the heating plate 12, reducing production and usage costs.

[0091] Please refer to Figure 6 and Figure 7 The bracket assembly 11 is also provided with a light-emitting component 16, which is electrically connected to the control board 20.

[0092] Specifically, in this embodiment, the light-emitting component 16 is mounted on the bracket assembly 11 and connected to the control board 20 via an electrical connection, and is regulated by the control board 20. The control board 20 can send corresponding signals to the light-emitting component 16 according to the working status of the electric clamp (such as power-on, heating, reaching the preset temperature, etc.) to control the light-emitting state of the light-emitting component 16. For example, it can control the light-emitting component 16 to display different colors of light according to different temperatures, and make the light-emitting component 16 stay on or flash according to different working states.

[0093] The light-emitting component 16 provides users with intuitive operational status indicators. For example, when the device is powered on, the light-emitting component 16 illuminates, indicating that the device is powered on; during heating, the light-emitting component 16 flashes, indicating to the user that the device is heating up; once the preset temperature is reached, the light-emitting component 16 remains constantly lit, informing the user that it is ready for use. This allows users to clearly understand the working status of the electric clamp, avoiding user experience issues or safety hazards caused by misoperation, thus improving the ease of use and safety of the device. At the same time, the lighting effect of the light-emitting component 16 also enhances the product's aesthetics and recognizability, increasing user satisfaction with the product.

[0094] like Figure 7 , Figure 10 and Figure 11 As shown, the light-emitting component 16 includes a light guide 161 and an LED light source 162 located on one side of the light guide 161. The light guide 161 is disposed on the bracket assembly 11, and at least a portion of the light guide 161 is exposed to the outside.

[0095] The light guide 161 can be transparent or semi-transparent. The LED light source 162 is positioned towards the light guide 161. The light emitted by the LED light source 162 can be refracted by the light guide 161 and thus emitted from the exposed portion of the light guide 161 to the outside for easy observation by the user. The light guide 161 can be exposed to the outside on both sides in the width direction, allowing the light emitted by the LED light source 162 to be emitted from both sides of the light guide 161. This solution eliminates the need for two LED strips; only one LED strip is placed in the middle of the light guide 161, and the light is refracted to both sides by the light guide 161, thus saving costs.

[0096] In this embodiment, the light-emitting component 16 is installed inside the cavity of the housing 111. The light guide 161 is U-shaped and includes a base plate 1611 and two side plates 1612. A first cover plate 116 is placed on the base plate 1311 of the light guide 161 and is located between the two side plates 1612, so that the two side plates 1612 of the light guide 161 are exposed to the outside from between the first cover plate 116 and the housing 111. The LED light source 162 can be disposed in the housing 111. Since the light guide 161 has light-guiding properties, the light emitted by the LED light source 162 can be refracted by the light guide 161 and thus diffused to the outside from the positions of the two side plates 1612 for user observation.

[0097] Please see Figure 1 and Figure 14 This utility model also proposes a hair styling clamp, which includes two hinged clamp assemblies 10 for clamping hair; wherein, each clamp assembly 10 includes a support assembly 11, a mounting frame 13 and a heating plate 12, the heating plate 12 is mounted on the mounting frame 13, the mounting frame 13 is connected to the support assembly 11, and the mounting frame 13 is floatable relative to the support assembly 11, and a vent 14 is formed between the mounting frame 13 and the support assembly 11, penetrating the clamp assembly 10; the clamp assembly 10 also includes a blocking member 17 located at the vent 14, the blocking member 17 being disposed on the support assembly 11 or the mounting frame 12.

[0098] Please continue reading. Figure 14 The blocking member 17 is located between the bracket assembly 11 and the mounting bracket 12 to block the through vent 14 and prevent hair from passing through the vent 14 and exiting the clip assembly 10. The blocking member 17 has various structures; in one embodiment, the blocking member 17 is a baffle.

[0099] The blocking member 17 can extend in a direction that coincides with or is spaced apart from the central axis of the clamping plate assembly 10. The blocking member 17 is disposed on one of the bracket assembly 11 and the mounting bracket 12, while the other of the bracket assembly 11 and the mounting bracket 12 can have a clearance groove to avoid the blocking member 17. In one embodiment, the mounting bracket 12 has the blocking member 17 on the side facing away from the heating plate 12, and the bracket assembly 11 has a clearance groove on the side facing the mounting bracket 12. The mounting bracket 12 is floatable relative to the bracket assembly 11, and the blocking member 17 floats relative to the bracket assembly 11 and moves within the clearance groove. It is understood that when the mounting bracket 12 floats to its lowest position, i.e., when the distance between the bracket assembly 11 and the heating plate 12 is minimal, the end of the blocking member 17 can have a gap with the bottom of the clearance groove, thereby avoiding interference and reducing heat transfer.
