Description

Technical Field

[0001] This invention belongs to the field of hair styling tools technology, and particularly relates to a hair straightener and a hair straightener head. Background Technology

[0002] A hair straightener is a common hair styling tool. It is usually used by placing the hair to be processed into the gap of the straightener head, clamping the hair, and heating the hair. By gradually moving the position of the hair clamped by the straightener head, the hair can be styling into a straight state.

[0003] In related technologies, hair straighteners have an open end on one side and a hinged end on the other. During use, hair enters through the open end, and then is manually pressed closed to hold the hair for styling. When the external force is removed, the open end automatically returns to its open state. Therefore, when clamping hair, a firm manual grip must be maintained at all times, and the tension from the automatic opening must be overcome, affecting the user experience. Summary of the Invention

[0007] In some embodiments, each of the straightening components is provided with at least two reset members, and the reset members are spaced apart.

[0008] In some embodiments, the hair straightener further includes: a heat insulation element disposed between the housing and the hair straightening assembly, the heat insulation element being at least used to block the transfer of heat from the hair straightening assembly to the housing; wherein the reset element is located between the heat insulation element and the hair straightening assembly.

[0009] In some embodiments, the heat insulation component is provided with a receiving groove, one end of the reset component is fixed in the receiving groove, and the other end of the reset component is connected to the hair straightening component.

[0010] In some embodiments, a heat insulation gap is formed between the heat insulation element and the hair straightening component.

[0011] In some embodiments, the heat insulation component is provided with a first guide structure, and the hair straightening component is provided with a second guide structure. The first guide structure and the second guide structure cooperate to guide the movement of the hair straightening component.

[0012] In some embodiments, the hair straightening assembly includes: a heating element for heating the hair; and a retaining shell movably disposed within the shell, wherein the heating element is mounted on the retaining shell and at least partially exposed thereout; wherein the resetting element abuts against the retaining shell to drive the retaining shell to maintain the clamping state.

[0013] In some embodiments, at least one anti-clamping gap is provided between the fixed shell and the end of the heating element for inserting hair to prevent hair from getting caught; or, the ends of the two heating elements for inserting hair abut against each other.

[0014] In some embodiments, the fixed shell includes: a first shell with a first splicing structure; and a second shell with a second splicing structure, wherein the first splicing structure and the second splicing structure are detachably connected; wherein the heating element has a first connecting structure, and both the first shell and the second shell have a second connecting structure, the first connecting structure and the second connecting structure being connected; or the heating element has a first connecting structure, one of the first shell and the second shell is integrally formed with the heating element, and the other of the first shell and the second shell has a second connecting structure, the first connecting structure and the second connecting structure being connected.

[0015] In some embodiments, one of the first splicing structure and the second splicing structure is configured as a buckle, and the other of the first splicing structure and the second splicing structure is configured as a slot, with the buckle engaged in the slot.

[0016] In some embodiments, a positioning structure is provided between the ends where the first shell and the second shell are connected.

[0017] In some embodiments, the first shell and the second shell are connected to form a mounting groove, and the heating element is disposed in the mounting groove.

[0018] In some embodiments, the heating element includes a heating element and a heat conductor, the heat conductor having an internal mounting cavity, and the heating element being mounted within the mounting cavity; wherein the first connecting structure is disposed on opposite edges of the heat conductor along its length.

[0019] This invention also provides a hair straightener, including a body and a hair straightener head as described in any of the above embodiments, wherein the hair straightener head is connected to the body.

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0036] The specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction. For example, different combinations of specific technical features can form different embodiments and technical solutions. To avoid unnecessary repetition, the various possible combinations of the specific technical features in this invention will not be described separately.

[0037] In the following description, the terms "first," "second," etc., are used merely to distinguish different objects and do not indicate that the objects have the sameness or relationship. It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to the orientation under normal use conditions, while "left" and "right" refer to the left and right directions shown in the corresponding diagrams, which may or may not be the left and right directions under normal use conditions.

[0038] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. "A plurality of" means two or more.

[0039] This invention provides a hair straightener 100, primarily used for straightening hair. Specifically, the straightener 100 shapes hair to be straightened, changing its shape to make it straighter and smoother. Specifically, the straightener 100 transfers heat to the hair through a heating element (straightening component), causing changes in the hair's keratin molecules. Under the influence of heat, the disulfide bonds in the hair are broken, making the hair softer and more malleable. Thus, after the hair is heated and straightened, the new shape is fixed upon cooling, resulting in straightened hair. Of course, during the hair straightening process, chemicals can be used to help the straightened hair maintain its straightness for a longer period. The specific operation or method of straightening hair in this invention is not described in detail here.

[0040] like Figure 1 and Figure 2 As shown, the hair straightener 100 includes a housing 1, a hair straightening assembly 2, and a reset member 3. The housing 1 has a hollow interior forming a receiving cavity 10 for accommodating and mounting other components. The shape of the housing 1 can be designed according to factors such as aesthetics, practicality, and ease of manufacturing. In this embodiment, the housing 1 is exemplified as being cylindrical, with a hollow interior forming the receiving cavity 10. Furthermore, at least one end of the housing 1 is provided with an opening communicating with the receiving cavity 10, through which other components are mounted into the receiving cavity 10.

[0041] Specifically, such as Figure 1 and Figure 2 As shown, the hair straightening component 2 is used for hair styling. The hair straightening component 2 is disposed within the receiving cavity 10, and at least two are arranged opposite each other. At least one of the two hair straightening components 2 is movable to reciprocate relative to the housing 1. A hair-holding gap 20 is provided between the two oppositely arranged hair straightening components 2. The hair to be processed is inserted into the hair-holding gap 20, whereby the two oppositely arranged hair straightening components 2 jointly clamp the hair, styling it to a straight state.

[0042] In this embodiment of the invention, two opposing straightening components 2 are configured to maintain a hair-clamping state. That is, under normal conditions, the two opposing straightening components 2 tend to move closer together, allowing them to maintain contact or have a certain width of hair-accommodating gap 20. The width of this gap 20 does not affect the clamping force generated by the two straightening components 2 when hair is inserted between them, thus clamping the hair. By configuring the two opposing straightening components 2 in a hair-clamping state, the hair inserted between them can be automatically clamped, and the space for accommodating the hair can be automatically adjusted without manual operation. Compared to a straightening head 100 that opens at one end and requires manual clamping, this straightening head 100 automatically clamps the hair simply by inserting it, making operation much more convenient.

[0043] The two opposing hair straightening components 2 are configured to maintain a clamping state. This can be achieved by the hair straightening components 2 themselves possessing elastic deformation properties, thereby limiting their installation position to either contact each other or maintain a hair-accommodating gap 20 of a certain width. When hair is inserted between the two hair straightening components 2, it will compress the two components, causing elastic deformation to accommodate the inserted hair. Furthermore, the hair straightening components 2, through their own restoring elastic deformation, will exert a clamping force on the hair, maintaining it in a clamped state. Thus, the elastic deformation properties of the hair straightening components 2 themselves enable the two opposing hair straightening components 2 to maintain a hair-clamping state.

[0044] In some embodiments, such as Figure 2 As shown, a reset member 3 is provided within the receiving cavity 10. This reset member 3 can generate a driving force to drive the two opposing straightening components 2 to maintain the hair clamping state. The reset member 3 is located within the receiving cavity 10 and can be directly connected to the housing 1, or it can be close to the housing 1 but with a small gap and not in direct contact. After hair is inserted between the two straightening components 2, the straightening components 2 are squeezed and move, thus contacting the reset member 3. This causes the reset member 3 to be subjected to force, pushing the straightening components 2 to move back to the initial state, thereby enabling the two opposing straightening components 2 to be maintained in the clamping state.

[0045] Specifically, the reset member 3 can generate a driving force, thereby driving the straightening component 2 to move and remain in a clamping state. To reliably maintain the clamping state of the two opposing straightening components 2, at least one of the two opposing straightening components 2 can be provided with a reset member 3, so that under the driving force generated by the reset member 3, at least the straightening component 2 can move closer to the other straightening component 2, realizing the clamping function. Of course, both opposing straightening components 2 can also be provided with a reset member 3, and the reset member 3 can be connected to the corresponding straightening component 2. In this way, the movement between the two straightening components 2 can be driven by the corresponding reset member 3, which can be either closer or farther apart. When the two are farther apart, the gap formed is used for the hair to be processed to be inserted, while when they are closer together, the inserted hair can be clamped.

[0046] By setting the reset member 3, at least one straightening component 2 can be driven to move relative to the other straightening component 2. In this way, when processing hair, it is only necessary to put the hair between the two straightening components 2, and the reset member 3 can clamp the put-in hair, so that no manual force is required to clamp the hair. The operation is simple and the convenience of use is improved.

[0047] The reset element 3 can be a mechanism that provides telescopic movement after being energized, such as a motor screw mechanism or a telescopic rod. In this case, the movement of the hair straightening component 2 can be automatically controlled by detecting whether hair is inserted. In this embodiment of the invention, the reset element 3 is set as a part that generates driving force by undergoing elastic deformation, such as a spring or a spring sheet. It is set to keep the reset element 3 in a compressed state under normal conditions, thereby maintaining the force that generates restorative deformation. Under this force, the connected hair straightening component 2 moves towards the direction of the other hair straightening component 2, that is, the two hair straightening components 2 remain close to each other under normal conditions, forming a clamping state.

[0048] In some embodiments, a notch is provided on the housing 1 to allow hair to be inserted between the two straightening components 2. Specifically, the notch is provided on the side wall of the housing 1, so that the hair to be processed can be inserted through the notch into the hair-holding gap 20 between the two opposing straightening components 2 and held therein. The position of the notch on the housing 1 can be opposite to the gap formed by the relative opening between the two straightening components 2, so that the hair can be inserted directly. Of course, it can also be provided in other positions without being opposite each other, as long as the hair can be inserted. Alternatively, two notches can be provided opposite each other on the housing 1, with each notch corresponding to the gap formed by the relative opening between the two straightening components 2. In this way, the inserted longer hair can be located on opposite sides of the housing, and the hair can be continuously straightened by moving the straightening head 100 relative to the held hair, thus improving the ease of operation. In this configuration, the opening at one end of the housing 1 can be made into a trumpet shape to guide the hair into the gap between the two straightening components 2.

[0049] This invention provides a hair straightener 100, comprising a housing 1, straightening components 2, and a resetting member 3. The housing 1 has an internal receiving cavity 10, within which the straightening components 2 are disposed. At least two straightening components 2 are arranged opposite each other, with the two opposing components in a clamping state capable of holding hair. The resetting member 3 drives the two opposing straightening components 2 to remain in the clamping state. Thus, because the two straightening components 2 always remain close together, the hair inserted between them is automatically clamped, and the clamping space is automatically adjusted. Driven by the resetting member 3, the clamped state is maintained at all times, eliminating the need for manual force to clamp the hair. This simplifies the hair styling process, making it easy for users and improving the user experience.

[0050] In some embodiments, such as Figure 2 As shown, each hair straightening component 2 is equipped with at least two reset members 3, which are spaced apart. This arrangement ensures that each hair straightening component 2 has at least two reset members 3 providing driving force. This relatively large driving force allows the hair straightening component 2 to move reliably and maintain its clamping state, thus achieving reliable hair clamping. Specifically, the multiple reset members 3 connected to each hair straightening component 2 can be evenly distributed to ensure balanced force on the hair straightening component 2, thereby improving the smoothness and stability of its movement. Moreover, driven by multiple reset members 3, even if a single reset member 3 fails, the hair straightening component 2 can still be driven to move, improving the reliability of its hair clamping movement.

[0051] In some embodiments, such as Figure 2As shown, since the hair straightener 2 generates heat when powered on, this heat is transferred to the housing 1 during use, especially for extended periods, causing the housing 1 to heat up and affecting the user's grip. Therefore, in this embodiment of the invention, a heat insulation component 4 is provided between the housing 1 and the hair straightener 2. This heat insulation component 4 is used to at least block the heat from the hair straightener 2 from being transferred to the housing 1. That is, the heat generated by the hair straightener 2 is blocked by the heat insulation component 4 and will not be directly transferred to the housing 1. Instead, the heat generated by the hair straightener 2 must first be transferred to the heat insulation component 4 before it can be transferred to the housing 1. This reduces the temperature of the housing 1, effectively preventing the housing 1 from becoming too hot and affecting the user's grip, or from posing a safety hazard due to excessively high temperature. The heat insulation component 4 effectively blocks the possibility of heat transfer to the housing 1, significantly improving the comfort and safety of operating the hair straightener 100.

[0052] When a heat insulation component 4 is provided, it is closer to the hair straightening assembly 2 than the housing 1, allowing the reset component 3 to be positioned between the heat insulation component 4 and the hair straightening assembly 2. Thus, the reset component 3 can directly act on the hair straightening assembly 2. Furthermore, to improve the reliability of the reset component 3's installation position, a receiving groove 41 can be provided on the heat insulation component 4. One end of the reset component 3 is fixed within the receiving groove 41, and the other end is connected to the hair straightening assembly 2. In this way, the receiving groove 41 limits the installation position of the reset component 3, ensuring its stability and preventing deviation, thus reliably driving the movement of the hair straightening assembly 2.

[0053] Optionally, to improve the heat insulation effect of the heat insulation component 4, it can be made of a material with low thermal conductivity, thereby reliably achieving the heat insulation effect. Moreover, the heat insulation component 4 also serves as part of the housing of the hair straightener 100, thereby improving the overall structural strength of the hair straightener 100.

[0054] Specifically, the heat insulation component 4 is disposed between the hair straightening assembly 2 and the housing 1. The heat insulation component 4 can be connected to the housing 1, while the hair straightening assembly 2 can be connected to the housing 1 and / or the heat insulation component 4. The hair straightening assembly 2 can be installed and fixed in various ways to meet different design requirements.

[0055] In some embodiments, the hair straightening component 2 is movably disposed within the housing 1, and can reciprocate towards or away from the heat insulation component 4 within the housing 1. To improve the heat insulation effect on the housing 1, a heat insulation gap 42 can be formed between the heat insulation component 4 and the hair straightening component 2. That is, the heat insulation component 4 and the hair straightening component 2 are not in complete contact, but are separated by a gap. Specifically, even when the two opposing hair straightening components 2 are moved away from each other to their maximum positions, the hair straightening component 2 and the heat insulation component 4 are still not in complete direct contact. In this way, the heat on the hair straightening component 2 is mainly transferred to the heat insulation component 4 through the air. Since the air has low heat conduction efficiency, the rate at which the heat insulation component 4 heats up can be further reduced, thereby reducing the efficiency and total amount of heat transferred to the housing 1, effectively preventing the temperature on the housing 1 from becoming too high.

[0056] In this embodiment of the invention, a heat insulation component 4 is provided, and a heat insulation gap 42 is formed by spacing it between the hair straightener 2 and the heat insulation component 4. Thus, the hair straightener 100 has at least two heat insulation solutions: heat insulation by the heat insulation component 4 and heat insulation gap 42. This dual heat insulation design prevents the temperature on the housing 1 of the hair straightener 100 from becoming excessively high. This ingenious design improves user comfort and safety.

[0057] In some embodiments, the heat insulation member 4 at least covers the side of the hair straightening component 2 facing the housing 1. With this configuration, the side of the hair straightening component 2 facing the housing 1 is covered by the heat insulation member 4, so that the hair straightening component 2 does not directly contact the housing 1, and thus the heat on the hair straightening component 2 is not directly transferred to the housing 1, thereby improving the effect of the heat insulation member 4 in blocking temperature transfer.

[0058] In some embodiments, to improve the smoothness of the hair straightening component 2's movement within the housing 1, a first guide structure can be provided on the heat insulation member 4, and a second guide structure can be provided on the hair straightening component 2. The first and second guide structures cooperate to guide the movement of the hair straightening component 2. Specifically, the first and second guide structures can cooperate and provide a matching structure for guiding and limiting the movement of the hair straightening component 2 relative to the housing 1. This allows the movement of the hair straightening component 2 within the housing 1 to remain smooth, guided by the first and second guide structures. Consequently, when hair is inserted, the two opposing hair straightening components 2 can smoothly move away from each other to insert the hair. After the hair is inserted, they can smoothly move closer together to clamp the hair. The cooperative arrangement of the first and second guide structures provides a reliable guarantee for the smooth and automatic movement of the hair straightening component 2 within the housing 1, effectively clamping the hair.

[0059] In some embodiments, such as Figure 2 and Figure 3As shown, the first guiding structure includes a guide post 431 disposed at one end of the heat insulation component 4 along its length, and the second guiding structure includes a guide hole 211 disposed at one end of the straightening assembly 2 along its length, corresponding to the guide post 431, with the guide post 431 passing through the guide hole 211. This arrangement allows the guide post 431 to provide guidance in the direction of movement. By passing the guide post 431 through the guide hole 211, the straightening assembly 2 can move along the guide post 431, thereby guiding and limiting the movement of the straightening assembly 2. This arrangement has a simple overall structure and good guiding effect.

[0060] In some other implementation schemes, such as Figure 2 and Figure 3 As shown, the first guiding structure can also include a guide groove 432 disposed at the other end of the heat insulation component 4 along its length, and the second guiding structure can also include a guide block 212 disposed at the other end of the straightening component 2 along its length, corresponding to the guide groove 432, with the guide block 212 slidably disposed within the guide groove 432. That is, the first guiding structure and the second guiding structure are respectively configured as a guide groove 432 and a guide block 212 capable of relative movement, resulting in a simple structure and convenient installation. By placing the guide block 212 within the guide groove 432 and allowing it to slide along the guide groove 432, the movement direction of the straightening component 2 can be effectively guided and limited. Furthermore, a cooperating limiting structure, such as a limiting step structure, can be provided between the guide block 212 and the guide groove 432 to limit the movement position of the guide block 212 within the guide groove 432, thereby limiting the proximity of the two straightening components 2.

[0061] In some embodiments, such as Figure 3 As shown, the heat insulation component 4 and / or the hair straightening component 2 are also provided with limiting components 5 to restrict the movement range of the hair straightening component 2. Specifically, since the hair straightening component 2 is movably disposed within the housing 1, when the hair to be processed is loaded between two opposing hair straightening components 2, the two hair straightening components 2 are simultaneously squeezed to move in opposite directions. Thus, by providing limiting components 5, which can be limiting pieces or limiting posts with a preset height, the movement range between the two hair straightening components 2 can be limited, thereby limiting the maximum distance between the two hair straightening components 2. Therefore, it not only limits the maximum amount of hair that can be loaded, but also avoids the problem of excessive compression of the hair straightening component 2 due to loading too much hair, thus better ensuring the safety of the overall structure. At the same time, limiting the maximum amount of hair loaded can also ensure the hair processing effect, preventing the problem of poor heating effect and poor processing effect due to loading too much hair.

[0062] Specifically, the limiting member 5 can be disposed on the inner wall of the heat insulation member 4 facing the straightening component 2, or it can be disposed on the outer surface of the straightening component 2 in the direction of movement of the heat insulation member 4, or both methods can be used simultaneously. In the embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the limiting member 5 is provided on the outer wall of the guide post 431. When the straightening assembly 2 moves along the guide post 431 and comes into contact with the limiting member 5, its movement position is limited. This arrangement integrates motion guidance and motion range limiting into one unit, improving the overall structural compactness. Furthermore, the limiting member 5 and the guide post 431 can be integrally molded, which is beneficial for manufacturing.

[0063] In some embodiments, such as Figure 1 and Figure 2 As shown, the hair straightening assembly 2 includes a heating element 22 and a fixing shell 23. The heating element 22 is used to heat the hair to improve the effect of hair styling. The fixing shell 23 is movably disposed within the housing 1. The heating element 22 is mounted on the fixing shell 23 and at least partially exposed thereout, allowing the inserted hair to contact the heating element 22 exposed outside the fixing shell 23, thereby heating the hair. The heating element 22 can be an object that generates heat when energized, such as an electric heating plate, electric heating wire, or electric plate, and is shaped according to design requirements. The heating element 22 is mounted on the fixing shell 23 and at least partially exposed thereout. In this way, the fixing shell 23 provides support for the mounting position of the heating element 22. When energized, the heating element 22 heats up and can directly contact the hair for heat treatment. The reset member 3 abuts against or is connected to the fixed shell 23. The fixed shell 23 can be driven to move by the reset member 3, which in turn drives the heating member 22 to move synchronously. This allows for adjustment of the position of the hair to be accommodated and for maintaining the clamping of the hair, thus ensuring that the hair is always in a clamping state.

[0064] The heating element 22 and the fixing shell 23 can be installed by snap-fitting or by using screws or similar fasteners. Alternatively, the fixing shell 23 can be fitted over part of the heating element 22 for a fixed installation. There are various installation methods, as long as the heating element 22 can be reliably fixed and at least a portion of the fixed heating element 22 can protrude outside the fixing shell 23.

[0065] Specifically, in the case where the direct-drive assembly 2 is configured to include a heating element 22 and a fixed shell 23, the reset element 3 is disposed between the heat insulation element 4 and the fixed shell 23, the heat insulation gap 42 is formed between the fixed shell 23 and the heat insulation element 4, and the second guide structure is disposed on the fixed shell 23.

[0066] In some embodiments, such as Figure 5 and Figure 7 As shown, the hair to be processed is typically inserted through the open ends of the two straightening components 2. Therefore, an anti-pinch gap 24 is provided at least between the fixing shell 23 and the heating element 22 at the end for inserting the hair to prevent hair from getting stuck. That is, the fixing shell 23 and the heating element 22 at the open end are spaced apart, so that even if hair enters the anti-pinch gap 24, the width of the anti-pinch gap 24 is greater than the thickness of the hair, allowing the hair to move freely within the anti-pinch gap 24, thus preventing the hair from getting stuck. In other words, during use, hair that enters the anti-pinch gap 24 can smoothly detach from it without getting stuck, effectively avoiding the pulling and pain caused by hair getting stuck, and improving the user's actual comfort.

[0067] In some embodiments, two heating elements 22 may be used to abut against each other at the ends where the hair is inserted. In this way, after the hair is inserted between the two heating elements 22, the hair can be heated from two opposite sides by the two heating elements 22, so that the hair can be heated evenly and the heating efficiency of the hair can be improved, thereby improving the effect of heating the hair.

[0068] Specifically, the width of the anti-pinch gap 24 can be reasonably designed according to the diameter of a typical hair. In this embodiment of the invention, the width of the anti-pinch gap 24 is set to a range of 0.3mm to 0.6mm. For example, it can be 0.3mm, 0.4mm, 0.45mm, 0.5mm, or 0.6mm. It can also be any other value within the range of 0.3mm to 0.6mm. Thus, the width of the anti-pinch gap 24 is several times larger than the diameter of a hair, thereby not only reliably preventing hair from being pinched, but also effectively avoiding affecting the product's aesthetics due to an excessively large gap size, ensuring the product's appearance integrity and quality.

[0069] In some embodiments, such as Figure 2 and Figure 4As shown, the fixed shell 23 includes a first shell 231 and a second shell 232. The first shell 231 and the second shell 232 mainly serve as the shell portion, providing mounting support for the heating element 22. The first shell 231 is provided with a first splicing structure 2311, and the second shell 232 is provided with a second splicing structure 2321. The first splicing structure 2311 and the second splicing structure 2321 are detachably connected. This allows the first shell 231 and the second shell 232 to be easily assembled and connected to each other. Specifically, by configuring the fixed shell 23 as a first shell 231 and a second shell 232 that can be spliced ​​together for the installation of the heating element 22, the manufacturing difficulty of the fixed shell 23 is reduced compared to using a one-piece fixed shell 23 structure, and the ease of assembly and connection is also improved. That is, compared to the longer one-piece fixed shell 23, the split fixed shell 23 reduces the manufacturing difficulty of ensuring overall flatness consistency, and can be installed separately during assembly, reducing the operating space required during assembly and facilitating assembly. Furthermore, the two shells 231 and 232 are respectively provided with splicing structures, which can easily and conveniently splice the two together. After splicing, the connection is stable and not easy to loosen, thus ensuring the overall structural strength and meeting the product's strength requirements.

[0070] Of course, in some embodiments, the fixed shell 23 can also be configured to be formed by splicing more splicing units (such as the first shell 231, the second shell 232, the third shell, etc.) together, and the splicing units are connected to each other by setting splicing structure to form a whole.

[0071] Specifically, the first splicing structure 2311 on the first shell 231 and the second splicing structure 2321 on the second shell 232 can be configured as matching hook structures, mortise and tenon structures, or flexible plug-in structures, etc., so that the first shell 231 and the second shell 232 can be quickly assembled and connected when spliced ​​together. Compared with the connection by screws or glue, less assembly operation is required, and the connection is convenient.

[0072] In some embodiments, such as Figure 4 As shown, the heating element 22 is provided with a first connecting structure 223, and both the first shell 231 and the second shell 232 are provided with a second connecting structure 233. The first connecting structure 223 and the second connecting structure 233 are connected to each other. That is, both the first shell 231 and the second shell 232 are provided with a second connecting structure 233, which can be connected to the first connecting structure 223 on the heating element 22. In this way, the heating element 22 can be fixedly installed on the first shell 231 and the second shell 232, which is convenient for assembly and connection, and is stable and reliable.

[0073] Specifically, the first connecting structure 223 can be configured as a sliding groove, and the second connecting structure 233 can be configured as a connecting block that can be inserted into the sliding groove to achieve connection. The first connecting structure 223 can also be configured as a hook, and the second connecting structure 233 can be configured as a snap-fit ​​position for hook connection. The first connecting structure 223 can also be configured as a plug, and the second connecting structure 233 can be configured as a plug hole for plug insertion and locking connection. Of course, it is understandable that the configuration of the first connecting structure 223 and the second connecting structure 233 can be interchanged, provided that a proper connection is achieved. This method of achieving assembly connection between the fixed shell 23 and the heating element 22 through connecting structures not only facilitates connection and requires minimal operation, improving assembly convenience, but also ensures high connection reliability, preventing loosening and improving product quality stability.

[0074] In other embodiments, a first connecting structure 223 may be provided on the heating element 22, one of the first shell 231 and the second shell 232 may be integrally formed with the heating element 22, and the other of the first shell 231 and the second shell 232 may also be provided with a second connecting structure 233. The heating element 22 may then be provided with the first connecting structure 223, and the first connecting structure 223 and the second connecting structure 233 may be connected together. That is, either the first shell 231 or the second shell 232 may be integrally formed with the heating element 22, while the other may be detachably connected to the heating element 22 via a matching connecting structure. The two fixed shells 23 may still be connected by a splicing structure. This allows for quick assembly and connection with good reliability.

[0075] In this invention, the fixing shell 23 is configured as a first shell 231 and a second shell 232 that can be spliced ​​together. The first shell 231 and the second shell 232 are detachably connected through a splicing structure, making the connection operation simple and convenient. Furthermore, a first connecting structure 223 is provided on the heating element 22, and a second connecting structure 233 is provided on both the first shell 231 and the second shell 232; or one of the first shell 231 and the second shell 232 is integrally formed with the heating element 22, and the other of the first shell 231 and the second shell 232 is also provided with a second connecting structure 233. Thus, by connecting the first connecting structure 223 and the second connecting structure 233, the separately configured fixing shell 23 can be installed without the need for screws or adhesive, making the connection convenient.

[0076] In some embodiments, such as Figure 2 and Figure 4As shown, one of the first splicing structure 2311 and the second splicing structure 2321 is configured as a snap-fit, and the other is configured as a slot, with the snap-fit ​​engaging within the slot. That is, by configuring the first splicing structure 2311 and the second splicing structure 2321 as a snap-fit ​​and slot capable of matching connection, assembly and connection can be quickly achieved. The snap-fit ​​has elastic deformation properties, thus maintaining its connection position after being secured in the slot, resulting in high connection reliability. Specifically, the snap-fit ​​and slot are arranged in pairs, and the number is sufficient to ensure a reliable connection between the first shell 231 and the second shell 232, preventing loosening.

[0077] In some embodiments, such as Figure 5 As shown, a mounting groove 25 is formed by connecting the first shell 231 and the second shell 232, and the heating element 22 is disposed within the mounting groove 25. By placing a portion of the heating element 22 within the mounting groove 25, the installation position of the heating element 22 is not only defined, ensuring the stability of its installation, but the heating element 22 is also shielded by the first shell 231 and the second shell 232, providing heat insulation and improving safety during use. The heating element 22, while fixed within the mounting groove 25, also has a portion protruding outside the mounting groove 25, allowing it to directly contact the hair for heat treatment.

[0078] In some embodiments, a latching position may be provided within the slot, and the buckle may engage with the latching position at least once. In this way, the buckle hooks onto the latching position, and the latching position limits the connection position of the buckle, further improving the reliability of the connection between the first housing 231 and the second housing 232.

[0079] In some embodiments, such as Figure 4 and Figure 5 As shown, a positioning structure 26 is provided between the ends where the first shell 231 and the second shell 232 are connected. By providing the positioning structure 26, the connection position of the first shell 231 and the second shell 232 can be limited, improving the accuracy of the connection position. This not only ensures that the first shell 231 and the second shell 232 can be accurately connected without deviation, but also provides position guidance for the alignment and connection of the first splicing structure 2311 and the second splicing structure 2321, thereby achieving connection quickly and accurately.

[0080] In some embodiments, the positioning structure 26 includes two matching and connected positioning steps, with the first shell 231 and the second shell 232 connected at one end, respectively, having a positioning step. That is, the positioning structure 26 is configured with mutually matching positioning steps, the two positioning steps having essentially the same shape and being designed to connect after a 180° rotation. This not only achieves positioning during assembly but also, through the step structure, provides a larger contact area, improving the stability of the position after assembly.

[0081] In another embodiment, the positioning structure 26 can be configured to include a positioning platform and a connector that are mated together. One of the first shell 231 and the second shell 232 is provided with the positioning platform, and the other of the first shell 231 and the second shell 232 is provided with the connector, which overlaps the positioning platform. That is, the positioning platform and the connector work together to locate the splicing position of the first shell 231 and the second shell 232. The shape of the positioning platform and the shape of the connector can be matched for connection, offering good flexibility in configuration.

[0082] The splicing connection between the first shell 231 and the second shell 232 is improved by the positioning structure 26 set between them, which enhances the convenience and reliability of the splicing connection.

[0083] In some embodiments, such as Figure 4 As shown, in the configuration where both the first shell 231 and the second shell 232 are provided with second connecting structures 233, the second connecting structures 233 can be respectively provided on both sides of the edges along the length direction of the first shell 231 and the second shell 232, and the heating element 22 is respectively provided with first connecting structures 223 on opposite sides along the length direction. Specifically, in order to have a large contact area between the heating element 22 and the hair during heat treatment, the heating element 22 is configured as a regularly shaped elongated strip. Therefore, to achieve a reliable connection between the heating element 22 and the first shell 231, and with the second shell 232, connecting structures are respectively provided on both sides along the length direction. This not only makes the location of each connecting structure readily visible, facilitating assembly, but also allows for limiting connections on opposite sides, improving the stability of the connection.

[0084] In some embodiments, the second connecting structure 233 is configured as a connecting buckle, and the first connecting structure 223 is configured as a connecting groove, with the connecting buckle slidably engaging within the connecting groove. That is, by setting the connecting buckle within the connecting groove and connecting the two together, the heating element 22 can be fixedly installed on the first shell 231 and the second shell 232. The structure is simple, easy to set up, and not only convenient to operate and connect, but also has good connection stability.

[0085] In some embodiments, the second connecting structure 233 is spaced apart along the length direction of the first shell 231 and / or the second shell 232; the first connecting structure 223 is continuously arranged along the length direction of the heating element 22. Specifically, by spaced apart the second connecting structures 233, not only can a reliable connection with the first connecting structure 223 be achieved, but the manufacturing difficulty can also be reduced, processing can be facilitated, and materials can be saved.

[0086] In some embodiments, where the first shell 231 and the heating element 22 are integrally formed, a second connecting structure 233 is provided on the second shell 232, and a corresponding first connecting structure 223 is provided on the heating element 22. The second connecting structure 233 and the first connecting structure 223 are connected. Furthermore, the second connecting structure 233 is provided on both sides of the length direction edge of the second shell 232, and the first connecting structure 223 is provided on both sides of the length direction edge of the heating element 22. This provides a large contact area between the second shell 232 and the heating element 22, enabling a stable connection between them.

[0087] In some embodiments, such as Figure 1 and Figure 4 As shown, heat dissipation holes 27 communicating with the mounting groove 25 are provided on the first shell 231 and / or the second shell 232. Specifically, since the heating element 22 generates heat after being powered on, heat dissipation holes 27 are provided on the first shell 231 and / or the second shell 232 to dissipate heat in the mounting groove 25, reduce the temperature on the fixed shell 23, and also to dissipate residual heat on the heating element 22 after use, so that the temperature on the heating element 22 can be reduced more quickly, making it easier to store the whole unit.

[0088] The heat dissipation holes 27 can be arranged in multiple ways along the length of the first shell 231 and / or the second shell 232, with each heat dissipation hole 27 spaced at appropriate intervals to improve the reliability of heat dissipation. Furthermore, the outline shape of the heat dissipation holes 27 can be circular or polygonal, etc., to ensure reliable heat dissipation without affecting the overall structural strength.

[0089] In some embodiments, such as Figure 2 and Figure 5 As shown, the heating element 22 includes a heating element 221 and a heat conductor 222. A mounting cavity 224 is formed inside the heat conductor 222, and the heating element 221 is installed within the mounting cavity 224. Simultaneously, first connecting structures 223 are provided on opposite edges along the length of the heat conductor 222 to achieve overall installation and fixation of the heating element 22. Specifically, the shape of the mounting cavity 224 formed inside the heat conductor 222 matches the shape of the heating element 221, thereby allowing the heating element 221 to be installed and fixed within the heat conductor 222. This heat conductor 222 has good thermal conductivity and is designed for direct contact with hair. Thus, the heat generated by the heating element 221 can be promptly dissipated through the heat conductor 222 to heat-treat the hair.

[0090] In some embodiments, a heat-conducting layer, such as one formed of graphene material, may be provided on the heat conductor 222, which can further improve the heat conduction effect of the heat conductor 222, make the heat distribution more uniform, and improve the consistency of hair treatment.

[0091] In some embodiments, such as Figure 6 As shown, a deformation groove 225 is provided on the heat conductor 222, and a portion of the heating element 221 is held within the deformation groove 225. Specifically, by fixing the heating element 221 in the receiving cavity 10 within the heat conductor 222 and clamping and fixing the heating element 221 by compressing the heat conductor 222 to cause deformation, the heating element 221 and the heat conductor 222 can make full contact for heat conduction. Therefore, a deformation groove 225 is also provided on the heat conductor 222, allowing a portion of the heating element 221 to be inserted into the deformation groove 225. This allows the portion of the heating element 221 located within the deformation groove 225 to be clamped and fixed when the heat conductor 222 is compressed, thereby improving the stability of the heating element 221 fixed within the heat conductor 222 and enabling timely and smooth heat conduction between the heating element 221 and the heat conductor 222.

[0092] like Figure 8 As shown, this embodiment of the invention also provides a hair straightener 600, including a body 61 and a straightener head 100 as described in the above embodiment, with the straightener head 100 connected to the body 61. The body 61 can be configured to be held and used in hand, and its interior mainly contains an operable control circuit board, buttons, and power supply components. The straightener head 100 is connected to the body 61, thereby enabling control such as power on / off switching, and thus control of the heating function switch. This allows the straightener head 100 to be powered on and heated as needed, clamping the hair for straightening heat treatment. The straightener head 100 has advantages such as automatically clamping the hair and preventing the housing 1 from overheating. By adopting the straightener head 100, the hair straightener 600 also possesses the advantages of the straightener head 100, making it convenient to use and significantly improving the user experience.

[0093] In some embodiments, the housing 1 and the body 61 can be fixedly connected, so that after the overall assembly is completed, the straightener 100 and the body 61 become a non-detachable structure, and the overall connection has good stability.

[0094] In other embodiments, the housing 1 and the body 61 can be made detachable, allowing the straightener 100 connected to the body 61 to be replaced. This allows for selection of straighteners 100 with different hair-clamping capacities or heating efficiencies. To improve the reliability of the detachable connection between the straightener 100 and the body 61, such as... Figure 9 and Figure 10As shown, a first connector 12 can be provided on the housing 1, and a second connector 61 can be provided on the body 61. The first connector 12 and the second connector 61 are detachably connected. That is, the connection between the straightener 100 and the body 61 can be achieved through the connection between the first connector 12 and the second connector 61.

[0095] Specifically, the first connector 12 is connected to the second connector 61 and can generate an attraction. Under the action of this attraction, the straightener 100 and the body 61 can maintain a relatively stable connection, which reduces the possibility that the straightener 100 and the body 61 will separate due to accidental contact or vibration after being connected by external force, thus improving the user experience.

[0096] Specifically, the first connector 12 and the second connector 61 can be either elastic self-locking structures or magnetic adsorption structures, as long as the first connector 12 and the second connector 61 are connected after the straightener 100 is inserted into the body 61. If a magnetic attraction can be generated between the first connector 12 and the second connector 61, the first connector 12 can be configured as a magnetic component, and the second connector 61 as a ferromagnetic metal or alloy component; alternatively, only the second connector 61 can be configured as a magnetic component, and the first connector 12 as a ferromagnetic metal or alloy component; or both the first connector 12 and the second connector 61 can be configured as magnetic components, in which case the magnetism of the first connector 12 and the second connector 61 is opposite.

[0097] In some embodiments, such as Figure 9 and Figure 10 As shown, one of the housing 1 and the handle is provided with a slot 7, and the other end of the housing 1 and the handle is inserted into the slot 7 in the axial direction. Specifically, one of the straightener 100 and the body 61 has a slot 7 at one end in the axial direction, and the other end of the straightener 100 and the body 61 is inserted into the slot 7 in the axial direction. Alternatively, the straightener 100 may have a slot 7, and one end of the body 61 may be inserted into the slot 7; or the body 61 may have a slot 7, and one end of the straightener 100 may be inserted into the slot 7.

[0098] To facilitate the explanation of the implementation principle of slot 7, the structure is described with slot 7 opened in the hair straightener 100, and one end of the body 61 inserted axially into slot 7. Specifically, the body 61 can be a columnar body extending axially, and the diameter of any position of the body 61 is less than or equal to the inner diameter of slot 7; of course, the body 61 can also have a stepped surface, as long as the diameter of the part of the body 61 connected to the hair straightener 100 is less than or equal to the inner diameter of slot 7. However, regardless of which embodiment the body 61 is provided in, at least a portion of the body 61 is inserted into slot 7, and slot 7 covers at least a portion of the body 61 in the circumferential direction to form a circumferential limit for the body 61. The user can use slot 7 as an installation reference and insert the body 61 into slot 7 to achieve the initial installation of the body 61 and hair straightener 100, which is convenient for user operation.

[0099] When using the slot 7, corresponding connectors (first connector 12 and second connector 61) can be placed inside the slot 7. For example, when the straightener 100 has a slot 7, the first connector 12 can be placed inside the slot 7, while the second connector 61 is placed at the end of the body 61 that is inserted into the slot 7, located at the end. In this way, after being inserted into the slot 7, the first connector 12 and the second connector 61 can remain in contact or be relatively close, thereby generating a greater attraction and improving the stability of the connection between the straightener 100 and the body 61.

[0100] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
