Description

Technical Field

[0001] This utility model relates to an eyelash curler. Background Technology

[0002] Eye makeup is a key focus for women, such as using eyelash curlers to style eyelashes, creating a curled shape that makes the eyes more vibrant and attractive. Current eyelash curlers typically have two handles. To use them, one handle is pushed against the other to clamp the eyelashes, thus creating a curl. However, during operation, the unstable force direction can cause the two handles to misalign and jam. Even with springs, they may not return to their original position, affecting the makeup finish and significantly impacting the lifespan of the curler. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an eyelash curler with a simple structure, convenient operation, reliable resetting, and good performance.

[0004] To achieve the above objectives, this utility model provides an eyelash curler, including a first handle and a second handle, which are rotatably connected. A return spring abuts between the first handle and the second handle. A clamping head is provided at the end of the first handle, and a mating head is provided at the end of the second handle. A clamping groove is provided on the mating head. A first guide protrusion extends from the first handle toward the second handle, and a second guide protrusion extends from the second handle toward the first handle. A guide block and a guide groove are provided between the first guide protrusion and the second guide protrusion. The guide block and the guide groove slide in engagement. A first mating groove is provided on the first handle corresponding to the position of the second guide protrusion, and a second mating groove is provided on the second handle corresponding to the position of the first guide protrusion.

[0005] The benefits of this design are as follows: The sliding cooperation between the guide block and the guide groove prevents wobbling or jamming during handle opening and closing, ensuring a stable connection between the clamping head and the mating groove. This results in more even force distribution when clamping eyelashes, preventing breakage due to excessive force in certain areas and maintaining a natural and consistent curl. The first and second mating grooves form a wrapping limit on the guide protrusion, reducing frictional wear between the protrusion and the handle, preventing loosening of the guide structure after prolonged use, thus extending the overall lifespan of the eyelash curler and reducing the frequency of component replacement. The precise guide structure ensures a more consistent handle opening and closing stroke, allowing users to perform clamping actions without consciously adjusting their grip, making operation more effortless. Furthermore, during production and assembly, the guide block, guide groove, and mating groove can serve as positioning benchmarks, quickly achieving precise alignment between the first and second handles, reducing assembly errors, and improving production efficiency and product qualification rate.

[0006] As a further feature of this invention, the first grip is provided with a first connecting platform, the clamping head is connected to the first connecting platform, the second grip is provided with a second connecting platform, the mating head is connected to the second connecting platform, and the first connecting platform and the second connecting platform overlap and are rotatably connected by a connecting shaft.

[0007] The advantages of this design are: the overlapping design of the connecting platform reduces the spacing between components, making the eyelash curler more compact and easier to store in a makeup bag, thus improving portability. The connecting shaft concentrates the load of rotational stress, preventing the handle from being directly deformed by force, reducing the risk of loosening after long-term use, and improving the overall structural reliability.

[0008] As a further feature of this invention, the clamping head extends toward the second connecting platform with a first guide flange, the first guide flange abutting against the outer peripheral wall of the second connecting platform, and the arc of the contact surface between the first guide flange and the second connecting platform is adapted to the arc of the outer peripheral wall of the second connecting platform. The mating platform extends toward the first connecting platform with a second guide flange, the second guide flange abutting against the outer peripheral wall of the first connecting platform, and the arc of the contact surface between the second guide flange and the first connecting platform is adapted to the arc of the outer peripheral wall of the first connecting platform.

[0009] The benefits of this design are as follows: The guide flange adapts to the curvature of the outer wall of the connecting platform, forming a snug, sliding contact that eliminates wobbling caused by gaps. This makes the handle opening and closing smoother and more stable, avoiding any feeling of jamming and improving user comfort. The flange resists the rotational stress of the bearing portion, sharing the load with the connecting shaft, reducing single-point stress on the connecting shaft, and preventing wear or deformation of the shaft after long-term use. The flange remains in contact with the connecting platform wall as the handle rotates, forming a double guiding constraint that ensures precise alignment of the clamping head and the mating head during opening and closing, preventing eyelash clamping deviation caused by misalignment and improving makeup stability.

[0010] As a further feature of this utility model, the first grip is provided with a first limiting groove, and a first limiting protrusion is provided in the first limiting groove; the second grip is provided with a second limiting groove, and a second limiting protrusion is provided in the second limiting groove; the two ends of the reset spring are respectively sleeved on the first limiting protrusion and the second limiting protrusion.

[0011] The advantages of this design are as follows: The protruding pin positioning ensures that the spring's extension and retraction always occur along the axis, preventing localized force concentration caused by offset, thus preventing spring deformation or breakage and extending its service life. The limiting groove restricts the spring's lateral movement, and together with the protruding pin positioning, ensures that the grip returns to the same position each time it resets, avoiding reset deviation caused by spring offset and guaranteeing consistent clamping. Simultaneously, the fixed spring position and consistent extension and retraction stroke ensure that the grip's reset force remains uniform, preventing sudden changes in force and improving the user experience.

[0012] As a further feature of this invention, the first grip and the second grip are each provided with a plurality of anti-slip ribs.

[0013] The benefits of this design are as follows: When your hands are covered in foundation, mascara, or sweat, the anti-slip ridges increase the friction between your hand and the handle, preventing slippage during use and adapting to the complex hand conditions during makeup application; the ridges also reduce direct wear on the handle surface, preventing the handle from slipping and failing after long-term use, while protecting the handle material from aging due to fingerprints, oil residue, and other contaminants.

[0015] This utility model provides an embodiment of an eyelash curler, such as... Figures 1 to 2 As shown, the device includes a first grip 1 and a second grip 2, which are rotatably connected. A return spring 3 abuts between the first grip 1 and the second grip 2. A clamping head 11 is provided at the end of the first grip 1, and a mating head 21 is provided at the end of the second grip 2. A clamping groove 22 is provided on the mating head 21. A first guide protrusion 12 extends from the first grip 1 to the second grip 2, and a second guide protrusion 23 extends from the second grip 2 to the first grip 1. A guide block 24 and a guide groove 13 are provided between the first guide protrusion 12 and the second guide protrusion 23. The guide block 24 and the guide groove 13 slide and engage. A first mating groove is provided on the first grip 1 at the position corresponding to the second guide protrusion 23, and a second mating groove 25 is provided on the second grip 2 at the position corresponding to the first guide protrusion 12. The beneficial effects of this design are as follows: The sliding engagement between the guide block 24 and the guide groove 13 prevents wobbling or jamming during handle opening and closing, ensuring a stable connection between the clamping head 11 and the mating groove. This results in more even force distribution when clamping eyelashes, preventing eyelash breakage due to excessive force in certain areas, and maintaining a natural and consistent eyelash curl. The first and second mating grooves 25 form a wrapping limit on the guide protrusion, reducing frictional wear between the guide protrusion and the handle, preventing loosening of the guide structure after prolonged use, thus extending the overall lifespan of the eyelash curler and reducing the frequency of component replacement. The precise guide structure ensures a more fixed handle opening and closing stroke, allowing users to perform clamping actions without consciously adjusting their grip, making operation more effortless. Simultaneously, during production and assembly, the guide block 24, guide groove 13, and mating groove can serve as positioning benchmarks, quickly achieving precise alignment between the first handle 1 and the second handle 2, reducing assembly errors, and improving production efficiency and product qualification rate.

[0016] As a further feature of this embodiment, the first handle 1 is provided with a first connecting platform 14, and the clamping head 11 is connected to the first connecting platform 14. The second handle 2 is provided with a second connecting platform 26, and the mating head 21 is connected to the second connecting platform 26. The first connecting platform 14 and the second connecting platform 26 overlap and are rotatably connected by a connecting shaft. The advantages of this configuration are: this design, with overlapping connecting platforms, compresses the spacing between components, making the eyelash curler more compact and easier to store in a makeup bag, thus improving portability. The connecting shaft concentrates the rotational stress, preventing the handle from being directly deformed by force, reducing the risk of loosening after long-term use, and improving the overall structural reliability.

[0017] As a further feature of this embodiment, the clamping head 11 extends towards the second connecting platform 26 with a first guide flange 15. The first guide flange 15 abuts against the outer peripheral wall of the second connecting platform 26, and the curvature of the contact surface between the first guide flange 15 and the second connecting platform 26 matches the curvature of the outer peripheral wall of the second connecting platform 26. The mating platform extends towards the first connecting platform 14 with a second guide flange 27. The second guide flange 27 abuts against the outer peripheral wall of the first connecting platform 14, and the curvature of the contact surface between the second guide flange 27 and the first connecting platform 14 matches the curvature of the outer peripheral wall of the first connecting platform 14. The beneficial effect of this configuration is that the guide flange and the outer peripheral wall of the connecting platform are matched to form a close-fitting sliding contact, eliminating the shaking caused by gaps, making the opening and closing of the handle more stable and smooth, avoiding the feeling of jamming, and improving the comfort of use. The flange abuts against the rotating stress of the bearing part and shares the load with the connecting shaft, reducing the single-point force on the connecting shaft and avoiding wear or deformation of the shaft after long-term use. The flange always fits against the connecting platform wall as the handle rotates, forming a double guiding constraint, ensuring that the clamping head 11 and the mating head 21 are accurately aligned during opening and closing, avoiding eyelash clamping deviation caused by offset, and improving the stability of the makeup effect.

[0018] As a further feature of this embodiment, the first grip 1 is provided with a first limiting groove, in which a first limiting protrusion is provided; the second grip 2 is provided with a second limiting groove 28, in which a second limiting protrusion 29 is provided; and the two ends of the return spring 3 are respectively sleeved on the first limiting protrusion and the second limiting protrusion 29. The beneficial effects of this configuration are: the protrusion positioning ensures that the spring extension and contraction always proceed along the axis, avoiding localized force concentration caused by offset, preventing spring deformation or breakage, and extending its service life; the limiting groove restricts the lateral movement of the spring, and together with the protrusion positioning, ensures that the grip returns to the same position each time it resets, avoiding reset deviation caused by spring offset and ensuring consistent clamping; at the same time, the fixed spring position and consistent extension and contraction stroke ensure that the grip reset force is always uniform, avoiding sudden changes in force and improving the user experience.

[0019] As a further feature of this embodiment, the first grip 1 and the second grip 2 are each provided with a plurality of anti-slip ridges 16. The beneficial effects of this feature are: when the hands are covered with foundation, mascara, or sweat, the anti-slip ridges 16 can increase the friction between the hand and the grip, preventing slippage during use and adapting to the complex hand conditions during makeup application; the ridges can reduce direct wear on the grip surface, preventing the grip from slipping and failing after long-term use, while also protecting the grip material from aging due to fingerprints, oil residue, and other contaminants.
