Abstract
Description
Technical Field
[0001] This utility model belongs to the field of hair styling tool technology, specifically relating to a hair end anti-snagging structure. Background Technology
[0002] Currently, hair straighteners, curling irons, and other hair styling tools generally use a rigid clamping plate structure, where the upper and lower heating plates form a fixed gap to clamp the hair when closed. This design has significant drawbacks: Hair tip jamming and damage: Due to their sparseness and rough texture, the ends of the hair are easily caught by the edges of the rigid plates during straightening, leading to excessive pulling or even breakage; Insufficient adaptability: Traditional structures cannot dynamically adjust the clamping force, making it difficult to meet the diverse needs of different hair volumes and textures (such as fragile ends), limiting the user experience. While existing technologies have attempted to optimize the shape or surface coating of the heating plates, they have not fundamentally solved the problem of hair tips getting stuck. There is an urgent need for a clamping structure that can actively adapt to the hair's condition and provide elastic cushioning. Utility Model Content

Detailed Implementation
[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0032] like Figure 1-4 As shown, this utility model provides a hair-stopping structure for hair ends, applicable to hair styling tools such as straighteners or curling irons. The structure includes an upper clamping plate 1 and a lower clamping plate 2 that open and close together, hinged on the same side to allow for multi-angle opening and closing. At the opposite end away from the hinge side, the upper clamping plate 1 and the lower clamping plate 2 are respectively provided with opposing upper contact surfaces 11 and 21 for clamping hair in the closed state. Heating plates 3, made of aluminum, are embedded in both the upper contact surfaces 11 and 21. When the upper clamping plate 1 and the lower clamping plate 2 are in the closed state, the two heating plates 3 are slightly inclined and abut against each other at the ends away from the hinge, forming a gradually widening gap 31 between them. The width of the gap 31 gradually increases from the abutment point towards the hinge direction. The method of use and effect is as follows: During operation, hair is placed within this gradually widening gap 31, and the hair is heated by the heating plates 3.
[0033] In this process, especially when dealing with the ends of the hair, there are two significant problems: First, the ends are prone to getting stuck and damaged. Because the hair volume at the ends is reduced and the texture is often rougher, traditional clamping plate structures easily get stuck when clamping and straightening the ends, leading to excessive pulling and damage. Second, excessive clamping and jamming at the contact point. When too much hair is clamped at once, the two heating plates 3 are in rigid contact at the contact point, making this location prone to hair jamming. To effectively solve these two problems, this application adds at least one floating component 4 to the upper contact surface 11 and the lower contact surface 21. The floating component 4 is located on one side of the heating plate 3 and together with the heating plate 3 forms the clamping area. The floating component 4 adopts a buffer structure that can float up and down. Its key function is: adaptive buffering of clamping force. When clamping the ends of the hair (thin hair, rough ends) or clamping excessive hair, the floating component 4 can dynamically adapt to changes in hair thickness and condition by floating up and down, significantly reducing the local clamping force on the hair. When handling hair ends, the cushioning effect reduces the clamping force on the ends, effectively preventing the ends from getting stuck or being excessively pulled, thus reducing damage. When excessive hair is caught near the contact area, the floating cushioning characteristic of the floating component 4 provides additional tolerance, preventing jamming caused by hair accumulation at the rigid contact point. Therefore, the introduction of the floating component 4 achieves a smoother, jam-free hair end handling experience and better protects hair quality.
[0034] Specifically, such as Figure 5-6As shown, in one embodiment of this utility model, the edge region of the heating plate 3 is provided with a specially constructed mounting position 32. The floating component 4 is installed in the mounting position 32 and can elastically float up and down within it. The design considerations for placing the mounting position 32 at the edge are as follows: First, it prioritizes the action on the hair ends: When the user operates the straightener to straighten the hair, the hair ends (hair tips) first contact and enter the edge region of the straightener. By placing the mounting position 32 and the floating component 4 on the side (rather than the middle part) of the heating plate 3, it can be ensured that the floating buffer mechanism directly and preferentially acts on the most vulnerable hair ends, thereby providing more timely and effective protection and significantly reducing the risk of hair getting stuck at the ends. Second, optimized structural rigidity and reliability: When the floating component 4 elastically floats and generates a contact force, this force acts directly on the mounting position 32. Since the mounting position 32 and the heating plate 3 are manufactured using an integral molding process, and the heating plate 3 is firmly fixed on the upper and lower contact surfaces, a sufficiently rigid overall support structure is formed. This structural design can reliably withstand the long-term, repeated impact forces of the floating component 4, ensuring its cushioning performance remains stable over time. Simultaneously, this design strictly confines the floating space of the floating component 4 within the mounting position 32, physically isolating it from other precision components inside the clamping plate. This effectively avoids interference or damage to internal components that may be caused by floating motion, thus improving the overall structural durability.
[0035] Specifically, such as Figure 5-6 As shown, in one embodiment of this utility model, the floating component 4 mainly includes: a movable component 41, an actuating component that can move up and down along the mounting position 32, and an elastic component 42, an elastic element that provides buffering and resetting functions. The movable component 41 and the inner wall of the mounting position 32 together form a receiving cavity. The elastic component 42 is disposed within the receiving cavity. One end of the elastic component 42 abuts against the inner wall of the mounting position 32, and the other end abuts against the movable component 41. In the closed state (clamping hair): when the clamp closes and clamps the hair (especially the ends or thicker hair strands), the movable component 41 is subjected to pressure and moves inward, compressing the elastic component 42. The elastic deformation generated by the elastic component 42 absorbs part of the pressure, providing buffer space for the hair, thereby significantly reducing the clamping force on the hair (especially the ends) and effectively preventing hair from getting stuck. In the open state (reset): When the clamping plate is opened, the compressed elastic element 42 releases its stored elastic potential energy, pushing the movable element 41 to move outward, so that it automatically and elastically resets to the initial position, preparing for the next clamping operation.
[0036] It is worth noting that the elastic element 42 can be either a sheet or a spring, both of which can achieve the above-mentioned buffering and reset functions. In the preferred embodiment shown in the accompanying drawings, the elastic element 42 is a continuous V-shaped sheet. The working principle of the continuous V-shaped sheet is as follows: In the compressed state: when the movable part 41 is compressed, the force is transmitted to the V-shaped sheet, causing the included angle of its bent portion to increase (i.e., elastic deformation occurs), thereby providing the required buffering force; in the reset state: after the pressure is released, the V-shaped sheet relies on its own elastic restoring force to restore the included angle of the bent portion to the original angle, while driving the movable part 41 to reset.
[0037] Furthermore, such as Figure 6-8 As shown, the mounting position 32 and the movable component 41 are respectively provided with guide structures that face each other and extend vertically: the mounting position 32 is provided with a fixed arm 322, and the movable component 41 is provided with a movable arm 412. At the opposite ends of the fixed arm 322 and the movable arm 412, a first locking block 321 and a second locking block 411 extending laterally are respectively provided. When the movable component 41 elastically floats up and down, the fixed arm 322 provides guidance and necessary vertical movement space for the movable arm 412, ensuring that the movable component 41 moves stably along a predetermined path. When the clamp is in the closed state and the movable component 41 is subjected to greater pressure (such as clamping hair), the end of the movable arm 412 finally abuts against the inner wall of the mounting position 32. This abutting action forms a rigid limit, preventing the movable component 41 from being excessively squeezed. Opening State Limit (Anti-Disengagement): When the clamping plate opens and the movable part 41 moves back to its original position under the action of the elastic member 42, at the end of the return stroke (opening state), the first locking block 321 engages with the second locking block 411. This locking structure forms an end limit at the elastic return stroke, effectively preventing the movable part 41 from disengaging from the mounting position 32 due to the elastic force, ensuring that it always remains in the designed position and is ready for the next clamping.
[0038] It is worth noting that, such as Figure 8 As shown, when in the open state, the elastic member 42 is in an elastic compression state, and the elasticity it generates is sufficient to make the first locking block 321 of the movable member 41 engage with the second locking block 411.
[0039] Furthermore, such as Figure 6-8As shown, the relative height between the movable part 41 and the heating plate 3 on the contact surface of the floating component 4 dynamically changes with the state of the clamping plate, forming specific working characteristics: In the open state: the first locking block 321 and the second locking block 411 are locked together, and the movable part 41 is in the extreme position after reset. At this time, in the contact surface area, the protrusion height of the clamping surface of the movable part 41 is greater than the protrusion height of the clamping surface of the heating plate 3, that is, the movable part 41 protrudes more from the contact surface. In the closed state (pressed to the limit): when the movable part 41 is squeezed by the pressure of a hair until the movable arm 412 abuts against the inner wall of the mounting position 32 (reaching the extreme position). At this time, in the contact surface area, the heating plate 3 is recessed into the contact surface. Importantly, at both extreme positions of the movable part 41's entire elastic floating stroke (when it is open and closed), its clamping surface always maintains a height difference with the clamping surface of the heating plate 3. This dynamic relative height difference design has significant advantages: First, increased effective buffering stroke: It provides the movable part 41 with a larger compressible space (elastic stroke range). Second, enhanced buffering capacity: The larger stroke range directly translates into higher clamping force buffering capacity. The movable part 41 can absorb and mitigate greater pressure fluctuations. Third, superior anti-hair-snagging performance: When facing complex clamping conditions such as thicker, more tangled, or extremely fragile hair strands (especially the ends), this enhanced buffering capacity can more effectively adapt to changes in hair thickness, significantly reducing or even eliminating the risk of end-snagging, providing a smoother and more hair-protecting user experience.
[0040] Preferably, such as Figure 9 As shown, the number of floating components 4 is set to two, and they are arranged in a cross-symmetrical manner on the upper contact surface 11 and the lower contact surface 21, respectively. Correspondingly, the mounting positions 32 on the two heating plates 3 are also arranged in a cross-symmetrical manner. This cross-symmetrical layout structure of dual floating components has the following significant advantages: First, all-round end buffer protection: no matter which direction the user straightens the hair (forward or backward), since the floating components 4 are set in the edge areas on both sides of the clamp, the hair end can always obtain effective buffer protection when entering the clamp, significantly reducing the risk of hair getting stuck at the end under different operating directions. Second, maintaining uniform and stable gap between the heating plates: the cross-symmetrical arrangement of the two floating components 4 allows the elastic buffer force on both sides of the clamp when clamping the hair to cancel each other out or balance each other. This force balancing mechanism effectively avoids the phenomenon of uneven gap width caused by pressure on one side of the floating component 4, ensuring that the gap 31 formed between the two heating plates 3 remains uniform and consistent in the entire width direction (lateral direction). The uniformity of the gap 31 is crucial for the smoothness of the user's operation and the consistency of the straightening effect. This design eliminates the pulling sensation or uneven heating effect that may be caused by uneven gaps, thereby improving the overall comfort and stability of the user experience.
[0041] Preferably, such as Figure 10 As shown, the number of floating components 4 is set to two, located on the same side of the clamping plate and aligned vertically. The working principle and core advantages are as follows: When the clamping plate is in a closed clamping state, the two floating components 4 located on the upper contact surface 11 and lower contact surface 21 will directly contact each other and work together. This vertically aligned structural design has the following key advantages: The elastic elements (springs / sheets) of the two floating components 4 deform together when under pressure, equivalent to connecting two independent buffer units in series. Significantly increased overall buffering stroke and limit: The series working mode multiplies the effective compressible stroke (buffering limit) of the entire floating system. Regardless of the magnitude of the clamping force applied by the user, this enhanced buffering system provides a significantly increased elastic clearance space to match. It virtually eliminates the risk of excessive squeezing and jamming of hair (especially fragile hair ends) due to excessive clamping force. Even with different hair volumes, hair types, or user operating habits, a smooth and unobstructed clamping experience can be achieved.
[0042] Preferably, the number of floating components 4 is four, that is, the mounting positions 32 are provided on both sides of the heating plate 3, and two floating components 4 are provided in the upper contact surface 11 and the lower contact surface 21 respectively. The floating components 4 on the upper contact surface 11 and the lower contact surface 21 are respectively arranged vertically and vertically. This design combines the advantages of the above two embodiments, which can not only provide all-round buffer protection and maintain the uniform and stable gap between the heating plates, but also ensure the maximum buffer stroke and limit.
[0043] Preferably, such as Figure 11 As shown, the number of floating components 4 is set to one, installed on the upper contact surface 11 or the lower contact surface 21. This single floating component structure design maintains the basic elastic buffer function while having significant cost-effectiveness advantages: firstly, it simplifies the structure by reducing the number of floating components 4 and related mounting positions 32; secondly, it reduces manufacturing costs by simplifying the number of parts and assembly processes, directly leading to a reduction in production costs. This solution provides an economical option with basic anti-jamming protection for cost-sensitive applications.
[0044] Specifically, such as Figure 5As shown, at least one side of the movable component 41 is provided with a corner 413. This corner 413 (i.e., the guide edge that directly contacts the hair) can be designed as a rounded corner, a C-shaped corner, or a right angle. Each design has specific functional advantages: The core advantage of the rounded corner design (R-angle) is that during hair straightening, the smooth transition of the corner significantly reduces the frictional resistance between the hair fibers and the edge of the movable component. This makes the hair move more smoothly and naturally within the clamp, effectively reducing the pulling sensation and operational resistance, especially beneficial for protecting delicate hair ends. The core advantage of the right angle design is that the sharp right-angled edge provides stronger grip during the initial contact phase. This design helps to more firmly position and initially clamp the hair, preventing slippage when the clamp begins to close or move, laying the foundation for subsequent straightening operations.
[0045] The following is a detailed description of the working principle of this utility model: Initial operation: Open the clamp and place the hair within the gradually expanding gap 31 between the upper and lower heating plates 3; Closure buffer: When the clamp closes, the movable part 41 of the floating component 4 contacts the hair and moves inward under pressure, compressing the elastic part 42. Through elastic deformation, it absorbs pressure, significantly reducing the instantaneous clamping force on the hair ends; Dynamic adaptation: Pressure at the hair ends triggers the floating component 4 to sink, forming a buffer space to prevent jamming; Overload protection: The movable arm 412 abuts against the inner wall of the mounting position 32, limiting the maximum compression stroke; Reset and anti-slip: When the clamp opens, the first locking block 321 engages with the second locking block 411, ensuring the movable part 41 accurately resets; Thermal effect: The heating plate 3 continuously heats during the buffering process, achieving straightening without jamming. The floating component layout (single / double / cross / aligned) can be adapted to different usage scenarios as needed.
[0046] The innovations of this invention are as follows: Solving the problem of hair jamming at the ends: Through the elastic buffering mechanism of the floating component, it dynamically adapts to the sparseness and fragility of the hair ends, eliminating the risk of jamming and breakage during the straightening process, significantly improving hair care effects; Adapting to excessive hair: The large stroke buffer space of the floating component can accommodate excessive hair, avoiding rigid jamming at the contact point and ensuring smooth operation; Comprehensive compatibility: Flexible layout: Single component reduces costs, double cross layout achieves multi-directional anti-jamming, and double alignment layout enhances the buffering limit; Universal applicability: Adapts to different hair volumes, hair qualities, and operating forces, ensuring a high consistency in user experience; Long-term stability: The installation position and heating plate are integrally molded, providing rigid support and ensuring long-term reliable operation of the floating component; Production-friendly: Modular design is compatible with standardized production, and the single-component solution significantly reduces manufacturing costs.
