[0028] See Figures 1 to 3 The specific embodiment shown in this utility model discloses a hair straightener with a protective sleeve, comprising: a hair straightener body and a sleeve 30. The hair straightener body is provided with two heating plates 40 arranged opposite each other. The hair straightener body has an open state in which the two heating plates 40 are spaced apart from each other and a closed state in which the two heating plates 40 are adjacent to each other. The hair straightener body is also provided with a power supply component 50, a heating element 60 and a PCBA board 70. The power supply component 50 and the heating element 60 are electrically connected to the PCBA board 70. The heating element 60 is installed on the inner side of the heating plate 40. When the two heating plates 40 are in the closed state in which they are adjacent to each other, the sleeve 30 is sleeved on the outer periphery of the hair straightener body.

[0029] Specifically, when a hair straightener is in use, its surface temperature is high, and direct contact can easily cause burns. The sleeve 30 acts as an insulator, effectively preventing users from accidentally touching the straightener and causing injury, thus increasing safety. Additionally, the sleeve 30 also helps to neatly organize the straightener body. When not in use, the sleeve 30 can be used to close it up, reducing its footprint and making it easier to carry and store. In other words, the cleverly designed sleeve 30 allows the straightener to quickly and easily transform into a safe and neat state after heating and use, which not only improves the overall aesthetics of the product but also enhances the user experience and satisfaction.

[0030] More specifically, the power supply unit 50 can be a rechargeable battery, and the hair straightener can be used after charging or connected to AC power.

[0031] In one embodiment, the hair straightener body includes a first clamping arm 10 and a second clamping arm 20, the first clamping arm 10 and the second clamping arm 20 being hinged to allow the first clamping arm 10 and the second clamping arm 20 to move between the open state and the closed state, wherein one heating plate 40 is disposed at the free end of the first clamping arm 10 and the other heating plate 40 is disposed at the free end of the second clamping arm 20.

[0032] Specifically, one end of the first clamp arm 10 and one end of the second clamp arm 20 are hinged together. The heating plate 40 at the free end of the first clamp arm 10 is located on the side of the first clamp arm 10 facing the free end of the second clamp arm 20, and the heating plate 40 at the free end of the second clamp arm 20 is located on the side of the second clamp arm 20 facing the free end of the first clamp arm 10. When the free ends of the first clamp arm 10 and the second clamp arm 20 move closer together until the two heating plates 40 are adjacent, the hair straightener body is in a closed state. When the free ends of the first clamp arm 10 and the second clamp arm 20 move away from each other until the two heating plates 40 are spaced apart, the hair straightener body is in an open state. Using this type of hair straightener body allows for a larger opening angle, facilitating straight hair styling.

[0033] In one embodiment, there are two heating components 60, one of which is located at the free end of the first clamping arm 10, and the other is located at the free end of the second clamping arm 20.

[0034] Specifically, by setting heating elements 60 at the free ends of the first clamping arm 10 and the second clamping arm 20 respectively, it can be ensured that both heating plates 40 receive sufficient heat, thereby achieving uniform heating. This design helps avoid the problem of overheating or insufficient temperature of a single heating plate 40, improving the heating efficiency and effect of the hair straightener. Furthermore, the dual heating element configuration 60 can accelerate the heating speed, allowing the hair straightener to reach the required temperature more quickly. This not only shortens the user's waiting time but also improves the efficiency of straightening or curling. Additionally, the dual heating element configuration 60 can distribute the heating load, reducing the failure rate of a single heating element 60. Moreover, by precisely controlling the power and temperature of each heating element 60, the reliability and safety of the product can be further improved. Furthermore, users can adjust the power or temperature of the two heating elements 60 according to different hair types to meet different straightening or curling needs. This design makes the hair straightener more adaptable and flexible, able to meet the needs of more users.

[0035] In one embodiment, the heating component 60 includes a heat insulation bracket 61, a mica sheet 62, a heat insulation cotton 63, and a heating film 64. The heat insulation bracket 61 is installed on the first clamping arm 10 or the second clamping arm 20. The mica sheet 62, the heat insulation cotton 63, and the heating film 64 are installed on the heat insulation bracket 61 in sequence from the inside to the outside. The back of the heating plate 40 abuts against the heating film 64.

[0036] Specifically, the heating film 64 generates heat and transfers it to the heating plate 40, raising its temperature for straightening hair. Insulating cotton 63 is placed on the back of the heating film 64 to prevent excessive heat dissipation, thus improving heating speed. In other words, the heating film 64, as the main heating element, generates heat and transfers it to the heating plate 40, raising its temperature to heat and style the hair. The design of the heating film 64 allows heat to be transferred quickly and evenly to the heating plate 40, improving heating efficiency. The insulating cotton 63 on the back of the heating film 64 primarily prevents excessive heat dissipation, slowing down heat loss. The addition of the insulating cotton 63 helps improve heating speed because heat is more effectively concentrated on the heating plate 40, reducing unnecessary heat loss and improving the straightener's energy efficiency. The heat insulation bracket 61 and mica sheet 62 serve as support and protective layers for the heating element 60, ensuring the stable installation of the heating film 64 and the heat insulation cotton 63. The heat insulation bracket 61 prevents the heating film 64 from directly contacting the metal part of the clamp arm, avoiding the risk of possible short circuit or overheating. The mica sheet 62 provides additional heat insulation and insulation effects, further enhancing the safety of the hair straightener.

[0037] The heating plate 40 is snapped into the heat insulation bracket 61 to form a stable structure. This design helps to prevent the heating plate 40 from loosening or falling off during use, thereby ensuring the normal operation and safety of the hair straightener.

[0038] In one embodiment, an elastic pad 80 is further provided between the heat insulation bracket 61 and the first clamping arm 10 or the second clamping arm 20.

[0039] Specifically, the elastic pad 80 acts as a buffer and shock absorber between the heat insulation bracket 61 and the clamp arm. When the hair straightener is subjected to external force or vibration during use, the elastic pad 80 can absorb these impacts and vibrations, protecting the heat insulation bracket 61 and the clamp arm from damage. This helps extend the lifespan of the hair straightener while improving user comfort and safety. In addition, the addition of the elastic pad 80 makes the connection between the heat insulation bracket 61 and the clamp arm tighter and more stable. It can prevent the heat insulation bracket 61 from loosening or falling off due to vibration or external force, thereby ensuring the overall structural stability of the hair straightener. A stable structure helps the hair straightener maintain efficient heat transfer and uniform heating effect during operation.

[0040] Preferably, the elastic pad 80 is made of silicone, which has low production costs and helps reduce the overall manufacturing cost of the hair straightener. In addition, silicone is highly recyclable and can be recycled, reducing resource waste and environmental pollution.

[0041] In one embodiment, the end of the hair straightener body away from the sleeve 30 is also connected to a tail cap 90, the PCBA board 70 is connected to a toggle switch 100, and the tail cap 90 is connected to a push button 110 for cooperating with the toggle switch 100.

[0042] Specifically, the hair straightener body is equipped with a push-button switch for controlling the PCBA board 70. The toggle switch 100 and the push-button switch form a dual-switch design. To prevent accidental triggering of the push-button switch and automatic heating, before powering on, the push button 110 must be pushed to unlock the PCBA board 70 via the toggle switch 100, and only then can the push-button switch be activated to power on the hair straightener. In other words, the main purpose of the dual-switch design is to prevent accidental triggering of the push-button switch, which could cause the hair straightener to automatically power on and heat up unintentionally. This design effectively avoids safety hazards caused by misoperation or improper storage. Furthermore, by first pushing the push button 110 to unlock the PCBA board 70 via the toggle switch 100, and then activating the push-button switch, users can more clearly control the hair straightener's on / off state. This operation method reduces the safety risks caused by misoperation and improves the overall safety of the product. In addition, this design makes the hair straightener safer to carry or store. For example, during travel or daily life, users can place the hair straightener in their luggage without worrying about accidentally turning it on and heating up due to accidental button presses.

[0043] In one embodiment, the PCBA board 70 is mounted on the first clamping arm 10, the PCBA board 70 is provided with a plurality of indicator lights, and the first clamping arm 10 is provided with openings corresponding to the indicator lights.

[0044] Specifically, the indicator lights on PCBA board 70 can display the straightener's working status, such as heating status, temperature setting status, and power on / off status. By observing the indicator lights, users can intuitively understand the straightener's working status and perform corresponding operations or adjustments. Furthermore, the addition of indicator lights makes the straightener's operation more intuitive and convenient, eliminating the need for users to rely on other methods (such as touching the heating plate 40 to feel the temperature) to determine the straightener's working status, thus improving ease of use and comfort. At the same time, the flashing or color changes of the indicator lights can provide users with more operational prompts and feedback, such as the progress of temperature adjustment and remaining battery power.

[0045] In one embodiment, the PCBA board 70 is also connected to a light-blocking cotton 120, which is used to cooperate with the indicator light.

[0046] Specifically, the main function of the light-blocking cotton 120 is to prevent light interference between indicator lights, i.e., to prevent light crosstalk. In a hair straightener, if there is no proper isolation between indicator lights, light may leak from one indicator light to another, resulting in unclear display or misleading the user. The use of light-blocking cotton 120 can effectively solve this problem, ensuring that the light from each indicator light accurately displays its corresponding status. In addition, by preventing light crosstalk, light-blocking cotton 120 can improve the clarity of the indicator lights, allowing users to more accurately judge the working status of the hair straightener. This is very important for users, as clear and accurate indicator light displays can help them better control the use of the hair straightener and avoid misoperation or improper use.

[0047] In one embodiment, a light guide post 130 is also connected to the outside of the light-blocking cotton 120, and the light guide post 130 is used to cooperate with the opening.

[0048] Specifically, the main function of the light guide column 130 is to guide the light, ensuring that the light emitted by the indicator light can be emitted along a predetermined path (i.e., the opening). This design can effectively avoid light scattering or leakage, and improve the utilization rate and directionality of the light. In addition, through the guidance of the light guide column 130, the light can be emitted more concentratedly, forming a clear indication effect, making it easier for users to observe and understand the working status of the hair straightener.

[0049] In one embodiment, the power supply component 50 is mounted on the second clamping arm 20, and the second clamping arm 20 is connected to a negative electrode 140 and a positive electrode 150 adapted to the power supply component 50. The positive electrode 150 is provided with a support groove 151.

[0050] Specifically, the negative electrode 140 is supported by an internal spring. This design effectively prevents the negative electrode 140 from deforming or breaking due to excessive pressure when the hair straightener is dropped or impacted. The internal spring provides a certain degree of cushioning, protecting the negative electrode 140 from damage. In some designs, if the negative electrode 140 is not properly supported, it may not be able to spring back to its original position after being subjected to external force, resulting in poor contact with the power supply component 50 and affecting the normal operation of the hair straightener. The internal spring support design effectively solves this problem, ensuring that the negative electrode 140 can quickly spring back to its original position after being subjected to external force, maintaining good contact with the power supply component 50. In addition, the positive electrode 150 is equipped with a support groove 151, which further enhances the stability of the positive electrode 150. When the hair straightener is dropped or impacted, the support groove 151 can prevent the positive electrode 150 from collapsing or deforming, thereby avoiding the problem of poor contact with the battery. This design can improve the durability and reliability of the hair straightener.

[0051] In one embodiment, the second clamping arm 20 is also provided with a pull strap in the area where the battery is located. The pull strap facilitates the user's removal of the battery when replacing it. Traditional battery compartment designs may require the user to use some tools or skills to remove the battery, while the addition of the pull strap greatly simplifies this process. The user can simply pull the battery out, improving the convenience of battery replacement.

[0052] In one embodiment, the bottom of the free end of the second clamp arm 20 is provided with multi-segment teeth, allowing the product to perform simple hair styling functions while straightening hair. In other words, users can utilize these toothed structures to create more hairstyles, such as curls and waves, while straightening their hair. This design greatly increases the practicality and functionality of the hair straightener, meeting users' needs for different hair styles. Furthermore, the diverse hair styling functions enhance the overall user experience. Users do not need to purchase multiple hair styling tools; a single hair straightener with a multi-segment tooth design can easily achieve various hair styles. This design not only saves users' purchasing costs but also improves hair styling efficiency, allowing users to create their desired hairstyles more conveniently and quickly.

[0053] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
