[0033] Referring to Figures 1 to 3 The utility model provides a curler, include:
[0034] Handle 10;
[0035] Heat conduction cylinder 20, heat conduction cylinder 20 is installed to handle 10, be equipped with heating piece in heat conduction cylinder 20;
[0036] Curling cylinder 30, curling cylinder 30 is rotatably connected to handle 10, and curling cylinder 30 ring is equipped with the outer periphery of heat conduction cylinder 20, and
[0037] Hair clamping assembly, the hair clamping assembly includes hair clamping plate 41 and a plurality of springs 42, both sides of hair clamping plate 41 are equipped with a side ear 411, both ends of spring 42 are connected to curling cylinder 30 and corresponding side ear 411 respectively, at least one spring 42 is corresponding to each side ear 411, hair clamping plate 41 is elastically connected to the side of curling cylinder 30 towards heat conduction cylinder 20 through corresponding spring 42.
[0038] In this invention, the hair clamping plate 41 is elastically connected to the curling tube 30 by a spring 42. This allows the user to flexibly adjust the tightness of the hair wrapping according to the thickness of their hair during the curling process. Simultaneously, the hair clamping plate 41 secures the hair, preventing it from slipping or moving during curling or heating, thus ensuring more even wrapping of the hair on the heat-conducting cylinder 20 and improving the curling efficiency and effect of the curling iron. Furthermore, each side of the hair clamping plate 41 has a side ear 411, and each side ear 411 corresponds to a spring 42. The spring 42 is located on the side of the hair clamping plate 41. Compared to a design where the spring 42 is placed between the hair clamping plate 41 and the curling tube 30, installing the spring 42 at the side ears 411 on both sides of the hair clamping plate 41 allows the spring 42 and the hair clamping plate 41 to be at least partially parallel, reducing the radial dimension of the curling iron and facilitating its miniaturization.
[0039] Specifically, the diameter of the spring 42 gradually decreases along the direction close to the heat-conducting cylinder 20. This results in less hair entering the space between the pressure plate and the heat-conducting cylinder 20, thus reducing the pressure on the pressure plate and facilitating hair curling. Simultaneously, the gradually decreasing diameter of the spring 42 also means that it occupies less space during compression, further reducing the radial dimension of the curling iron and contributing to its miniaturization.
[0040] In one embodiment, the side of the hair clamping plate 41 facing the heat-conducting cylinder 20 is a hair clamping surface 412, which is arc-shaped. By making the hair clamping surface 412 arc-shaped, it can better conform to the natural curve of the hair, ensuring that the hair is heated evenly during the curling process and reducing hair damage caused by uneven heating. At the same time, the space between the arc-shaped hair clamping surface and the heat-conducting cylinder 20 is more uniform, allowing heat to be transferred to the hair more effectively, thereby speeding up the curling speed and improving the curling efficiency. Finally, the arc-shaped hair clamping surface can press the hair more evenly, forming a more natural and smooth curling effect, and also helps to reduce friction and resistance during the curling process, making the curling smoother. Of course, in other embodiments, a heating element can be installed on the hair clamping plate 41, thereby providing double-layer heating of the hair through the heat-conducting cylinder 20 and the hair clamping plate 41, thus improving the curling effect of the curling iron.
[0041] Furthermore, the curvature of the hair clamping surface 412 is greater than that of the heat-conducting cylinder 20. This makes it easier for the hair to be rolled between the hair clamping plate 41 and the heat-conducting cylinder 20 when the curling cylinder 30 rotates. At the same time, the larger curvature allows the pressure plate to form a stronger fixing force when pressing the hair, ensuring that the hair will not slip or loosen during the curling process.
[0042] Reference Figures 4 to 6 In one embodiment, the curling iron further includes a mounting plate 43. The curling barrel 30 has a mounting through hole 31. The mounting plate 43 is mounted on the side of the curling barrel 30 facing away from the heat-conducting cylinder 20 and covers the mounting through hole 31. The two ends of the spring 42 are respectively connected to the side ear 411 and the mounting plate 43. The hair clamping plate 41 is partially located within the mounting through hole 31. By providing the mounting through hole 31, the radial space occupied by the hair clamping plate in the curling iron can be reduced. Therefore, by placing at least a portion of the hair clamping plate within the mounting through hole 31, the radial dimension of the curling iron is reduced, which is beneficial for miniaturization. Simultaneously, the mounting through hole 31 also limits the movement of the hair clamping plate, restricting its movement along the circumference of the curling barrel 30, so that the hair clamping plate can only move in the radial direction close to the curling barrel 30, thereby improving the stability and reliability of the hair clamping plate.
[0043] In one embodiment, the mounting through hole 31 has two limiting protrusions 32 on its wall, which are arranged opposite to each other. The mounting plate 43 is spaced apart from the limiting protrusions 32 to form two first limiting grooves 33. The two side ears 411 are located in the corresponding first limiting grooves 33. The groove depth of the limiting groove is h, and the thickness of the side ear 411 is w2, where h > w2. That is, the side ears 411 of the hair pressing plate can move within the first limiting grooves 33, and the groove depth of the first limiting grooves 33 is the movement space of the hair pressing plate.
[0044] Specifically, the thickness of the hair clamping plate 41 is w1, and the shortest distance between the side ear 411 and the side of the hair clamping plate 41 away from the heat-conducting cylinder 20 is s, where s < 1 / 2w1. It can be understood that the side ear 411 is confined within the first limiting groove 33. Therefore, by limiting s to 1 / 2w1, the rebound space of the hair clamping plate 41 is increased, thereby making the hair pressing space between the curling cylinder 30 and the heat-conducting cylinder 20 larger, which in turn increases the pressing force of the hair pressing plate, thereby reducing the possibility of hair slipping between the heat-conducting cylinder 20 and the hair pressing plate, and thus improving the stability and reliability of the hair pressing plate.
[0045] Specifically, the bottom wall of the first limiting groove 33 and the side wall of the hair clipping plate 41 form a second limiting groove 34, and the spring 42 is located within the second limiting groove 34. By providing the second limiting groove 34, the spring 42 is limited by the second limiting groove 34 when subjected to compression deformation, making the spring 42 less prone to deformation, thereby improving the stability of the spring 42 during operation, and thus improving the stability and reliability of the hair clipping plate.
[0046] In one embodiment, the hair curler further includes a housing 50, which is connected to the handle 10 and surrounds the outer periphery of the curling barrel 30. The housing 50 provides protection for the curling barrel 30 and the outer layer, preventing burns to the user's skin due to overheating of the heat-conducting cylinder 20 during use, thereby improving the safety of the hair curler and enhancing the user experience.
[0047] Furthermore, the outer casing 50 is provided with a hair-holding slot 51, which is located at the end of the outer casing 50 away from the handle 10. By providing the hair-holding slot 51, it is easier for the user's hair to be rolled between the heat-conducting cylinder 20 and the curling cylinder 30. At the same time, the hair-holding slot 51 also facilitates the user to clean the heat-conducting cylinder 20, the curling cylinder 30, and the inner peripheral wall of the outer casing 50, so that the heat-conducting cylinder 20, the curling cylinder 30, and the outer casing 50 do not need to be disassembled for cleaning, thereby further improving the user experience.
[0048] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
