Description

Technical Field

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

[0002] A hair straightener is a hair styling tool used to straighten hair. It works by heating the plates, which alters the internal hydrogen bond structure of the hair under high temperature, thus achieving a styling effect. As an essential tool for modern hairstyling, it continuously innovates in technology, materials, and functions to meet the styling and hair care needs of different users.

[0003] Common hair straighteners mainly consist of an upper clamping arm and a lower clamping arm. One end of the upper clamping arm and one end of the lower clamping arm are rotatably connected. The upper clamping arm has an upper heating plate, and the lower clamping arm has a lower heating plate. The upper and lower heating plates are arranged correspondingly. When the user needs to use the hair straightener to style the hair, the user needs to firmly grasp the upper and lower clamping arms. The upper and lower clamping arms close and clamp the hair, and the heating plates heat the hair for styling. After styling the hair, the user releases their hands, and the upper and lower clamping arms spring open and separate, making it convenient to use.

[0004] However, current hair straighteners still have many shortcomings. For example, during use, users need to hold the upper and lower clamp arms tightly for a long time, which can cause wrist pain and is quite strenuous. In addition, it is difficult for users to control the grip force evenly. If the user grips too hard or too softly, the hair will be clamped too tightly or too loosely, failing to achieve the desired hair styling effect. Therefore, improvements are needed.

[0005] The above information is provided as background information only to aid in understanding this disclosure and does not constitute an assertion or admission that any of the above content can be used as prior art relative to this disclosure. Utility Model Content

[0051] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0052] In the description of this utility model, it should be understood that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component that is centrally positioned therein. When a component is considered to be "set" on another component, it can be directly set on the other component or there may be a component that is centrally positioned therein.

[0053] Furthermore, terms such as "long," "short," "inner," and "outer" indicate orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings. They are used only for the convenience of describing this utility model and do not indicate or imply that the device or component referred to must have this specific orientation or operate in a specific orientational configuration. Therefore, they should not be construed as limitations of this utility model.

[0054] The following is in conjunction with the appendix Figure 1-6 The technical solution of this utility model will be further illustrated through specific implementation methods.

[0055] Please refer to Figure 1 and Figure 2 This utility model provides a hair straightener, including a first clamping arm 1, a second clamping arm 2, a first magnetic element 3, a second magnetic element 4, a switching element 5, and a heating element 6.

[0056] The second clamping arm 2 is movably connected to the first clamping arm 1. The heating element 6 is disposed on the first clamping arm 1 and the second clamping arm 2. The heating element 6 is used to style the hair. The first magnetic element 3 is disposed on the first clamping arm 1. The second magnetic element 4 is disposed on the second clamping arm 2 and is disposed opposite to the first magnetic element 3. The switch element 5 is disposed on the first clamping arm 1 and connected to the first magnetic element 3, or disposed on the second clamping arm 2 and connected to the second magnetic element 4. The switch element 5 is used to control the first magnetic element 3 and the second magnetic element 4 to magnetically attract and fix each other or to loosen from each other.

[0057] In some embodiments, both the first clamping arm 1 and the second clamping arm 2 are long rod-shaped structures. One end of the first clamping arm 1 is rotatably connected to the second clamping arm 2 via a pivot. At this time, the first clamping arm 1 and the second clamping arm 2 can be pressed to drive them closer to each other until they close together. When the first clamping arm 1 and the second clamping arm 2 are released, the first clamping arm 1 and the second clamping arm 2 can be opened to make them move away from each other.

[0058] At this time, the heating element 6 is a heating plate, which is fixedly installed on the first clamping arm 1 and the second clamping arm 2 respectively, and the two heating plates are arranged opposite each other. When the first clamping arm 1 and the second clamping arm 2 are closed to each other, the two heating plates can clamp the hair and heat and style the hair to facilitate straightening.

[0059] In addition, the hair straightener also includes a control element connected to the heating element 6 to control the connection of the heating element 6. Specifically, the control element mainly includes components such as a circuit board, a main control chip, and a circuit module (not shown in the figure), which are mounted on the circuit board. The circuit board is installed in the first clamping arm 1 or the second clamping arm 2. The heating element 6 is electrically connected to the main control chip, and the main control chip is electrically connected to the circuit module. The circuit module is used to convert the mains power into a suitable voltage, which is connected to the heating element 6 so that the heating element 6 can obtain electrical energy. The main control chip controls the heating element 6 to heat up through the circuit module to achieve the heating control function. It can be understood that the control element only needs to be able to control the heating element 6 to generate heat, and the specific structure of the control element is not limited here.

[0060] In some embodiments, the switch element 5 is disposed on the first clamping arm 1 and connected to the first magnetic suction element 3. Specifically, the first magnetic suction element 3 is electrically connected to the circuit module, and the main control chip can control the circuit module to supply power to the first magnetic suction element 3. The switch element 5 is located between the circuit module and the first magnetic suction element 3, and is electrically connected to both the circuit module and the first magnetic suction element 3. The first magnetic suction element 3 can be started and stopped by operating the switch element 5. For example, pressing the switch element 5 can make the circuit module and the first magnetic suction element 3 connected, and the first magnetic suction element 3 is turned on; releasing the switch element 5 can make the circuit module and the first magnetic suction element 3 disconnected, and the first magnetic suction element 3 is turned off. When the first magnetic suction element 3 is turned on, it can cooperate with the second magnetic suction element 4 to generate a magnetic force, so that the first clamping arm 1 and the second clamping arm 2, which are closed to each other, can be attracted to each other. The user can perform shaping operations without having to hold the first clamping arm 1 and the second clamping arm 2 for a long time.

[0061] In other embodiments, the switch element 5 is disposed on the second clamping arm 2 and connected to the second magnetic element 4. Specifically, the second magnetic element 4 is electrically connected to the circuit module, and the main control chip control circuit module provides power to the second magnetic element 4. The switch element 5 plays the role of starting and stopping. The installation method and starting and stopping principle of the second magnetic element 4 are the same as those of the first magnetic element 3, and will not be described in detail here. When the second magnetic element 4 is turned on, it can cooperate with the first magnetic element 3 to generate magnetic attraction, so that the first clamping arm 1 and the second clamping arm 2, which are closed to each other, can be attracted and fixed to each other. The user can perform shaping operations without having to hold the first clamping arm 1 and the second clamping arm 2 for a long time.

[0062] Based on the above configuration, regardless of whether the switch element 5 is located on the first clamping arm 1 or the second clamping arm 2, the switch element 5 can control the first magnetic attraction element 3 or the second magnetic attraction element 4 to achieve the purpose of magnetically fixing the first clamping arm 1 or the second clamping arm 2. Therefore, no matter where the switch element 5 is located, and no matter whether the switch element 5 controls the first magnetic attraction element 3 or the second magnetic attraction element 4 to start or stop, it should be included in the scope of interpretation of this application.

[0063] In this embodiment, the switch element 5 is disposed on the first clamping arm 1 and connected to the first magnetic attraction element 3.

[0064] Based on the above settings, by operating the switch element 5, the first magnetic element 3 and the second magnetic element 4 are attracted to each other, thereby keeping the first clamping arm 1 and the second clamping arm 2 in a closed state under the action of magnetic attraction. The user only needs to press the switch element 5 with a little force to keep the switch element 5 on, without the need to manually control the clamping force, so that the clamping force of the first clamping arm 1 and the second clamping arm 2 on the hair is uniform and less likely to damage the hair. When it is necessary to release the hair straightener, the user only needs to release the switch element 5, and the magnetic attraction disappears, thus solving the problem of the hair straightener being difficult to use and difficult to control the grip force.

[0065] Continue to refer to Figure 1 and Figure 2 In some embodiments, the first magnetic element 3 is an electromagnet, the switching element 5 is connected to the electromagnet, and the second magnetic element 4 is a magnetic metal piece, with the electromagnet and the magnetic metal piece magnetically attracted to each other.

[0066] Specifically, the electromagnet is fixedly installed on the first clamping arm 1, and correspondingly, the switching element 5 is set on the first clamping arm 1 so that the electromagnet and the switching element 5 are closer together, which facilitates the installation of the structure; the magnetic metal part is fixedly installed on the second clamping arm 2. The magnetic metal part can be made of iron, cobalt, nickel, etc. Any material that can be magnetically attracted to the electromagnet can be tried, and no specific restrictions are imposed here.

[0067] Based on the above configuration, with the cooperation of the electromagnet and the magnetic metal parts, the first clamping arm 1 and the second clamping arm 2 can maintain the attraction action, and the attraction is stable and not easy to loosen.

[0068] Alternatively, in some other embodiments, the first magnetic element 3 is a magnetic metal piece, the second magnetic element 4 is an electromagnet, the switching element 5 is connected to the electromagnet, and the electromagnet and the magnetic metal piece are magnetically attracted to each other.

[0069] Specifically, the first magnetic element 3 is fixedly mounted on the first clamping arm 1, and the second magnetic element 4 is fixedly mounted on the second clamping arm 2. Correspondingly, the switching element 5 is mounted on the second clamping arm 2 to bring the electromagnet and the switching element 5 closer together, which facilitates the installation of the structure. The magnetic metal parts can be made of materials such as iron, cobalt, and nickel. Any material that can be magnetically attracted to the electromagnet can be used, and no specific restrictions are imposed here.

[0070] Based on the above setup, with the cooperation of the electromagnet and the magnetic metal parts, the first clamping arm 1 and the second clamping arm 2 can also be kept in a magnetically attracted position. It can be understood that no matter where the electromagnet and the magnetic metal parts are placed, the effect of magnetically fixing the first clamping arm 1 and the second clamping arm 2 can be achieved.

[0071] In this embodiment, the first magnetic element 3 is an electromagnet, the second magnetic element 4 is a magnetic metal part, and the switch element 5 is disposed on the first clamping arm 1.

[0072] Reference Figure 3 The switching element 5 includes a micro switch 51, a button 52, and a first spring 53. The micro switch 51 has a contact piece, which is activated when the contact piece is pressed down. The button 52 is movably disposed on the first clamping arm 1 or the second clamping arm 2 and abuts against the contact piece of the micro switch 51 to flexibly press down the contact piece. The first spring 53 is connected to the button 52 and is used to push the button 52 to elastically reset.

[0073] Specifically, the micro switch 51 is triggered by pressing the contact piece, thereby creating a connection between the circuit module and the electromagnet, resulting in a magnetic attraction effect. When the contact piece is released, it will spring back and reset, opening the circuit between the circuit module and the electromagnet, thus eliminating the magnetic attraction. At this time, the first clamping arm 1 and the second clamping arm 2 can be operated to open. The specific structure of the micro switch 51 is existing technology and is not specifically limited here.

[0074] It is understood that button 52 can be selected to be set on the first clamping arm 1 or the second clamping arm 2 depending on the specific setting position of the electromagnet. For example, when the first magnetic element 3 is an electromagnet, button 52 is set on the first clamping arm 1, and when the second magnetic element 4 is an electromagnet, button 52 is set on the second clamping arm 2. This achieves the purpose of setting the switching element 5 adjacent to the electromagnet, making the structural assembly more convenient, the spatial layout of the structure more reasonable, and improving the overall compactness of the structure. Therefore, whether button 52 is set on the first clamping arm 1 or the second clamping arm 2, it should be included in the scope of interpretation of this application, and no restriction is placed on the specific setting position of button 52.

[0075] Based on the above settings, to enable the electromagnet to start and stop, the first spring 53 is compressed by pressing down button 52. At the same time, button 52 presses down on the contact piece, and micro switch 51 turns on the circuit. The electromagnet receives electrical energy and generates magnetic attraction, at which point the electromagnet is in the starting state. When it is necessary to turn off the electromagnet, simply release button 52. Under the push of the first spring 53, button 52 is driven away from the contact piece, thereby opening the circuit and turning off the electromagnet. The above operation is simple, convenient, and quick, and the structural design is reasonable, which can greatly improve the user experience.

[0076] Continue to refer to Figure 3 In some embodiments, the first clamping arm 1 or the second clamping arm 2 is provided with a mounting hole 11, the button 52 is provided with a guide wall 521 on its periphery, the button 52 is located in the mounting hole 11, and the guide wall 521 slides against the hole wall of the mounting hole 11.

[0077] Specifically, when button 52 is installed on the first clamping arm 1, mounting hole 11 is provided on the first clamping arm 1; and when button 52 is installed on the second clamping arm 2, mounting hole 11 is provided on the second clamping arm 2. Here, the specific setting position of mounting hole 11 is not restricted.

[0078] In addition, the guide wall 521 is straight, and the wall of the corresponding mounting hole 11 is also straight. The opening contour of the mounting hole 11 matches the peripheral contour of the button 52. When the button 52 is located in the mounting hole 11, the guide wall 521 and the wall of the mounting hole 11 can smoothly abut against each other, thereby effectively improving the pressing feel of the button 52 and significantly optimizing the operating experience.

[0079] It should be added that, when setting the mounting hole 11, it is preferable to maintain a certain distance between the mounting hole 11 and the heating element 6 to prevent interference between the structures.

[0080] Continue to refer to Figure 3In some embodiments, a limiting flange 522 is provided on the periphery of the button 52. The limiting flange 522 abuts against the first clamping arm 1 or the second clamping arm 2 to limit the button 52 from falling off.

[0081] Specifically, the limiting flange 522 is integrally connected with the button 52 to achieve good connection stability. On this basis, the limiting flange 522 is located near the inside of the first clamping arm 1 or the second clamping arm 2, and the limiting flange 522 abuts against the inner wall of the outer shell of the first clamping arm 1 or the second clamping arm 2, thereby limiting the button 52 and preventing the button 52 from loosening. The structural stability of the button 52 during the pressing process is significantly improved.

[0082] Reference Figure 3 In some embodiments, the button 52 is provided with a guide post 523, and the first spring 53 is sleeved on the guide post 523.

[0083] Specifically, one end of the guide post 523 is integrally connected to the button 52, and the guide post 523 is inserted into the first spring 53 so that one end of the first spring 53 can be sleeved on the guide post 523. Under the action of the guide post 523, the first spring 53 can be positioned to prevent the first spring 53 from shifting during compression and extension. The structural stability of the first spring 53 is optimized and improved, and it can continuously provide the button 52 with a good rebound feel.

[0084] In some embodiments, button 52 is an elongated button 52. Specifically, the shape of button 52 can be rectangular or oblong. Correspondingly, the opening contour of mounting hole 11 is adapted to the shape of button 52. Based on the above settings, the elongated button 52 can obtain a larger pressing area and pressing space compared with conventional round or square buttons 52, making it easier for users to touch the switch button and making it more convenient for users to press.

[0085] Furthermore, there are multiple guide posts 523, and a first spring 53 is respectively fitted on each guide post 523. Any two guide posts 523 are located at the two ends of the button 52.

[0086] For details, please refer to... Figure 3 The specific number of guide posts 523 can be two, three or four, etc., and there is no specific limitation on the number. In this embodiment, there are two sets of first springs 53 and guide posts 523 used in pairs, and they are located at both ends of the button 52 respectively. At this time, no matter where the button 52 is installed, a relatively balanced support feel can be obtained, and the button 52 can be easily reset as a whole.

[0087] Based on this, when button 52 is elongated, by setting multiple guide posts 523 and a first spring 53, the button 52 can be supported and rebounded in multiple directions, which can prevent the button 52 from getting stuck or shifting during the pressing process, and the feel of use is further optimized and improved.

[0088] Reference Figure 4 In some embodiments, a second spring 7 is also included, which is located between the first clamping arm 1 and the second clamping arm 2. The second spring 7 is connected to the first clamping arm 1 and the second clamping arm 2 respectively, and is used to push the first clamping arm 1 and the second clamping arm 2 to open.

[0089] Specifically, the second spring 7 is arranged adjacent to the pivot of the first clamping arm 1 and the second clamping arm 2. The second spring 7 needs to be arranged at a certain distance from the switching element 5 to prevent the elastic force generated by the first spring 53 and the elastic force generated by the second spring 7 from being superimposed at the same position, thereby causing the switching element 5 to be accidentally touched and affecting the control feel.

[0090] Based on the above settings, after the hair styling is completed, and when the user releases the first clamping arm 1 and the second clamping arm 2, the second spring 7 can provide a mutual opening force for the first clamping arm 1 and the second clamping arm 2, so that when the user performs the styling operation next time, there is no need to open the first clamping arm 1 and the second clamping arm 2 again, and the practicality and convenience are further optimized and improved.

[0091] In some embodiments, the first clamping arm 1 is provided with a first positioning member 8, one end of the second spring 7 is connected to the first positioning member 8, the second clamping arm 2 is provided with a second positioning member 9, and the other end of the second spring 7 is connected to the second positioning member 9.

[0092] Based on the above settings, the two ends of the second spring 7 can be positioned using the first positioning member 8 and the second positioning member 9, so that the second spring 7 can maintain stable extension and retraction during the opening and closing of the first clamping arm 1 and the second clamping arm 2, thereby optimizing and improving the user experience.

[0093] Reference Figure 5 and Figure 6 In one embodiment, the first positioning member 8 is a positioning post 91 or a positioning groove 81. When the first positioning member 8 is a positioning post 91, the end of the second spring 7 is sleeved on the positioning post 91. When the first positioning member 8 is a positioning groove 81, the end of the second spring 7 is embedded in the positioning groove 81.

[0094] Specifically, when the first positioning element 8 is a positioning post 91, the positioning post 91 is integrally connected to the first clamping arm 1. The positioning post 91 is inserted into one end of the second spring 7, thereby causing the end of the second spring 7 to be sleeved on the positioning post 91. The positioning post 91 can provide a stable positioning support effect for the second spring 7.

[0095] In addition, when the first positioning member 8 is a positioning groove 81, the positioning groove 81 is recessed on the first clamping arm 1, and one end of the second spring 7 is inserted into the positioning groove 81. The groove wall of the positioning groove 81 provides support for the end of the second spring 7, which can also provide a stable positioning support effect for the second spring 7.

[0096] It is understood that the specific structure of the first positioning element 8 can be adjusted according to actual needs, and there are no specific restrictions here. In this embodiment, the first positioning element 8 is a positioning groove 81 structure as an example.

[0097] Furthermore, the second positioning element 9 is a positioning post 91 or a positioning groove 81. When the second positioning element 9 is a positioning post 91, the end of the second spring 7 is sleeved on the positioning post 91. When the second positioning element 9 is a positioning groove 81, the end of the second spring 7 is embedded in the positioning groove 81.

[0098] It is understandable that the positioning post 91 and the positioning groove 81 are set on the second clamping arm 2 in the same way as they are set on the first clamping arm 1, and will not be described in detail here. By setting the second positioning member 9 as the positioning post 91 or the positioning groove 81, a stable positioning support effect can be provided for the second spring 7.

[0099] In this embodiment, the second positioning element 9 is selected as a positioning post 91 as an example.

[0100] The hair straightener provided in this application has the following beneficial effects:

[0101] 1. It can balance the force of the hair clamp, which can reduce hair damage caused by uneven clamping force from the hand;

[0102] 2. It can reduce hand fatigue caused by holding the hair straightener for a long time.

[0103] Therefore, the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
