Description

Technical Field

[0001] This utility model relates to the field of hair straighteners, and in particular to a hair straightener that prevents scalding. Background Technology

[0002] Hair straighteners are common hair styling tools, typically consisting of two clamping arms that can be opened and closed. Heating plates are located on the inner sides of both clamping arms. After the user plugs the straightener into a power source, the heating plates on the clamping arms heat up. The user then holds the rotating end of the clamping arms, causing the two arms to close and the two heating plates to clamp the hair. By dragging the straightener downwards, the user pulls the hair, thus straightening it.

[0003] However, some beginners may not be able to control the force applied to the hair straightener with one hand. They may use their hands to close the opening and closing ends of the two clamping arms at the same time, so that the hair straightener can clamp the hair. The opening and closing ends of the clamping arms are close to the heating element, which is hotter and may burn the user. Utility Model Content

[0004] This application provides a heat-resistant hair straightener with multiple heat-resistant structures to reduce the probability of users being burned by the heating element when using the hair straightener.

[0005] The anti-scalding hair straightener provided in this application adopts the following technical solution:

[0006] A heat-resistant hair straightener includes two clamping arms hinged together. Heating elements are provided on the inner walls of the opening and closing ends of both clamping arms. A heat insulation assembly is provided on the opening and closing ends of each clamping arm. The heat insulation assembly includes an interconnected mounting sleeve and a protective plate. The end of each clamping arm is inserted into the mounting sleeve, and the protective plate covers the outer wall of the opening and closing ends of the clamping arms. A first mating part is provided on each clamping arm, and a second mating part is provided on the protective plate. The first mating part and the second mating part engage to prevent the mounting sleeve from detaching from the clamping arm.

[0007] By adopting the above technical solution and setting up heat insulation components, the user grips the hair straightener on two protective plates, thus preventing the user's hand from contacting the clamping arm and preventing the clamping arm from burning the user.

[0008] Preferably, the first mating part includes an anti-detachment block one disposed on the clamping arm, and the second mating part includes an anti-detachment block two disposed on the protective plate. The anti-detachment block one and the anti-detachment block two abut against each other, and the anti-detachment block one is located on the side of the anti-detachment block two closer to the mounting sleeve.

[0009] By adopting the above technical solution, the protective sleeve and protective plate are prevented from detaching from the clamping arm, ensuring the stability of the connection between the heat insulation component and the clamping arm.

[0010] Preferably, the anti-detachment block 2 has a guide slope on the side wall away from the mounting sleeve. When the clamping arm is inserted into the mounting sleeve, the anti-detachment block 1 collides with the guide slope, causing the anti-detachment block 2 to deform and flip outward, so that the anti-detachment block 1 can pass through the anti-detachment block 2 and move closer to the mounting sleeve. Finally, the anti-detachment block 1 and the side wall of the anti-detachment block 2 near the mounting sleeve abut against each other.

[0011] By adopting the above technical solution, when the heat insulation component is installed on the clamping arm, the support wall is inserted into the mounting sleeve. During the process of inserting the clamping arm into the mounting sleeve, the first anti-detachment block will collide with the guide slope, causing the second anti-detachment block to deform and deform, allowing the first anti-detachment block to approach the mounting sleeve. Finally, the support wall abuts against the inner wall of the mounting sleeve. At this time, the first anti-detachment block and the second anti-detachment block abut against the side wall of the mounting sleeve, thus preventing the installation from detaching from the clamping arm.

[0012] Preferably, the protective plate is provided with multiple support ribs, and the multiple support ribs abut against the clamping arm, so that a heat dissipation cavity is formed between the protective plate and the clamping arm.

[0013] By adopting the above technical solution, the setting of the support ribs prevents the protective plate from directly contacting the clamping arm. As a result, the heat from the clamping arm is less likely to be transferred to the protective plate, and the heat from the clamping arm will be transferred to the air through the heat dissipation cavity, making it less likely for the user to be burned when gripping the protective plate.

[0014] Preferably, the protective plate has a heat dissipation groove along its length, the heat dissipation groove connecting the heat dissipation cavity and the outside; multiple first anti-slip ribs are arranged on the groove wall of the heat dissipation groove, and the multiple first anti-slip ribs are arranged at equal intervals along the length of the heat dissipation groove.

[0015] By adopting the above technical solution, the opening of the heat dissipation groove further improves the speed of heat dissipation of the clamping arm, thereby further preventing the heat of the clamping arm from being transferred to the protective plate. The setting of multiple first anti-slip ribs can make the user grip the protective plate more stably.

[0016] Preferably, the protective plate has a gripping part at the end away from the mounting sleeve, and the distance from the end of the gripping part connected to the protective plate to the mounting sleeve is greater than the distance from the end of the heating element away from the mounting sleeve to the mounting sleeve. The gripping part has multiple second anti-slip ribs.

[0017] By adopting the above technical solution, the range of hair straightening with the hair straightener is the area of ​​contact between the hair and the heating element, which is the range from the user's hand to the mounting sleeve. When using the hair straightener, the user grasps the grip, ensuring that the heating element is fully in contact with the hair, thus guaranteeing the straightening range of the product.

[0018] Preferably, multiple comb rods are provided on one side wall of the protective plate, and the multiple comb rods are arranged at equal intervals along the length direction of the protective plate; the multiple comb rods on the two protective plates are symmetrically arranged, and the two heating plates are located between the multiple comb rods.

[0019] By adopting the above technical solution and incorporating comb bars, the hair can be combed while straightening. Simultaneously, when the hair is held in the straightener section, multiple comb bars prevent the user's fingers from contacting the heating element, thus preventing burns.

[0020] Preferably, one of the clamping arms has a first mounting cavity; the other clamping arm has a second mounting cavity; a spring is also provided between the two clamping arms, with one end of the spring inserted into the first mounting cavity and the other end of the spring inserted into the second mounting cavity.

[0021] By adopting the above technical solution, after pulling a portion of hair, the user releases the grip on the two clamping arms, and the spring will rebound, causing the two clamping arms to rotate away from each other and the two heating plates to move away, so that the hair straightener can continue to clamp the next portion of hair to be straightened.

[0022] The main technical effects of this utility model are reflected in the following aspects:

[0023] 1. This utility model is equipped with a heat insulation component, so that when the user holds the hair straightener, he / she holds the two protective plates, thereby preventing the user's hand from coming into contact with the clamping arm and thus preventing the clamping arm from burning the user.

[0024] 2. This utility model is equipped with multiple support ribs so that the protective plate does not directly contact the clamping arm. Therefore, the heat from the clamping arm is less likely to be transferred to the protective plate. The heat from the clamping arm will be transferred to the air through the heat dissipation cavity, making it less likely for the user to be burned when gripping the protective plate.

[0025] 3. This utility model is equipped with a gripping part, which ensures that the user is not burned when using this hair straightener, and also ensures the straightening range of the hair during use. Attached Figure Description

[0034] The present application will be further described in detail below with reference to the accompanying drawings, so that the technical solution of the present application can be more easily understood and mastered.

[0035] Reference Figures 1-4 This embodiment of an anti-scalding hair straightener includes two hinged clamping arms 1, each with a heating element 11 on its inner wall at the opening / closing end. One clamping arm 1 has a mounting cavity 12; the other clamping arm 1 has a mounting cavity 13. The mounting cavities 12 and 13 are located near the hinged ends of the two clamping arms 1. A spring 14 is also provided between the two clamping arms 1, with one end inserted in the mounting cavity 12 and the other end inserted in the mounting cavity 13. The spring force acts on the two clamping arms 1, causing the opening / closing ends of the two clamping arms 1 to move away from each other.

[0036] Reference Figure 2 , Figure 3 , Figure 5 A heat insulation component 2 is provided on the opening and closing end of the clamping arm 1. The heat insulation component 2 includes an interconnected mounting sleeve 21 and a protective plate 22. The end of the clamping arm 1 away from the spring 14 is inserted into the mounting sleeve 21, and the protective plate 22 covers the outer wall of the opening and closing end of the clamping arm 1. The circumferential sidewalls of the clamping arm 1 without the heating element 11 are all considered as the outer wall.

[0037] Reference Figure 2 , Figure 5 and Figure 6The clamping arm 1 is provided with a first mating part 3, and the protective plate 22 is provided with a second mating part 4. The first mating part 3 and the second mating part 4 are engaged to prevent the mounting sleeve 21 from detaching from the clamping arm 1. The first mating part 3 includes an anti-detachment block 31 provided on the clamping arm 1, and the second mating part 4 includes two anti-detachment blocks 41 integrally formed on the protective plate 22. The two anti-detachment blocks 41 are located on both sides of the protective plate 22. The anti-detachment block 31 abuts against the two anti-detachment blocks 41, and the anti-detachment block 31 is located on the side of the two anti-detachment blocks 41 closer to the mounting sleeve 21.

[0038] Reference Figure 2 , Figure 5 and Figure 6 The anti-detachment block 2 41 has a guide slope 42 on the side wall away from the mounting sleeve 21. When the clamping arm 1 is inserted into the mounting sleeve 21, the anti-detachment block 1 31 collides with the guide slope 42, causing the anti-detachment block 2 41 to deform and flip outward, so that the anti-detachment block 1 31 can pass through the anti-detachment block 2 41 and move closer to the mounting sleeve 21. Finally, the anti-detachment block 1 31 and the anti-detachment block 2 41 abut against the side wall of the mounting sleeve 21.

[0039] Reference Figure 2 , Figure 3 , Figure 6 and Figure 7 The protective plate 22 has multiple support ribs 51 on the side facing the clamping arm 1. These support ribs 51 abut against the clamping arm 1, forming a heat dissipation cavity 6 between the protective plate 22 and the clamping arm 1. The support ribs 51 prevent the protective plate 22 from directly contacting the clamping arm 1, making it less likely for heat from the clamping arm 1 to be transferred to the protective plate 22. The heat from the clamping arm 1 is then transferred to the air through the heat dissipation cavity 6, making it less likely for the user to be burned when gripping the protective plate 22.

[0040] Reference Figure 1 and Figure 2 The protective plate 22 has a heat dissipation groove 52 along its length direction, which connects the heat dissipation cavity 6 and the outside. Multiple first anti-slip ribs 53 are arranged on the groove wall of the heat dissipation groove 52, and the multiple first anti-slip ribs 53 are arranged at equal intervals along the length direction of the heat dissipation groove 52.

[0041] Reference Figure 1 and Figure 2 The protective plate 22 has a gripping part 54 at the end furthest from the mounting sleeve 21. The distance from the end of the gripping part 54 connected to the protective plate 22 to the mounting sleeve 21 is greater than the distance from the end of the heating element 11 furthest from the mounting sleeve 21 to the mounting sleeve 21. The gripping part 54 has multiple second anti-slip ribs 55. The protective plate 22 and the gripping part 54 cover the outer surface area of ​​the opening and closing end of the clamping arm 1 that the user may come into contact with during operation.

[0042] Reference Figure 1 and Figure 2The area within which a hair straightener straightens hair is the area where the hair contacts the heating element 11, which is the area from the user's hand to the mounting sleeve 21. When using the hair straightener, the user grips the handle 54, ensuring that the heating element 11 is fully in contact with the hair, thus guaranteeing the straightening range of the product.

[0043] Reference Figure 1 and Figure 2 Multiple comb rods 56 are provided on one side wall of the protective plate 22, and the comb rods 56 are arranged at equal intervals along the length of the protective plate 22. The multiple comb rods 56 on the two protective plates 22 are symmetrically arranged, and the two heating plates 11 are located between the multiple comb rods 56. The comb rods 56 are provided to comb the hair when straightening it. At the same time, the multiple comb rods 56 can prevent the user's fingers from touching the heating plates 11 at normal times, thereby preventing burns.

[0044] Of course, the above are just typical examples of this application. In addition, this application may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed in this application.
