Description

Technical Field

[0001] This utility model relates to the field of hair curling equipment, and more particularly to hair curling irons. Background Technology

[0002] Curling irons are a common styling tool for modern women. By heating the hair and changing its shape, they can easily achieve curls or straighten the hair, creating wavy and stylish hairstyles. Curling irons mainly consist of a handle, a heating element, and a curling mechanism. The curling mechanism holds the hair in place on the heating element, which then evenly distributes heat to the surface in contact with the hair, causing it to curl. To avoid overheating and causing frizz, burnt edges, or other problems, it's generally recommended to wet the hair before using a curling iron.

[0003] There are two common types of curling mechanisms: one is the curling barrel disclosed in the utility model patent CN209473929U, entitled "Automatic Hair Curler," which uses a rotating barrel to curl the hair onto the surface of a heating rod. However, heating wet hair generates steam and causes rapid moisture loss. The aforementioned curling barrel is short and has a small surface area, making it difficult to effectively prevent excessive moisture loss during curling, easily leading to frizz, burnt edges, and other problems. The other type is the clip disclosed in the invention patent CN111838931B, entitled "A Curling Tool." The clip is placed on the curling barrel and creates a clamping force between the barrels, fixing the hair to the barrel and achieving a curling effect after heating. However, the clip is long and has a large surface area, causing steam generated during heating to accumulate between the clip and the barrel, resulting in excessively high local temperatures and a large temperature difference between the edge and the center of the clip. This easily leads to localized frizz and affects the styling effect.

[0004] How to solve the above problems has become an urgent technical issue. Utility Model Content

[0005] The purpose of this invention is to provide a hair curler that can reduce the rate of moisture loss and effectively prevent excessive local temperature, thereby increasing the curling and shaping effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The curling iron provided by this utility model includes a handle, a heating rod, and a clip that can fit against the outer surface of the heating rod. The handle is provided with a controller and is connected to one end of the heating rod. The controller is electrically connected to the heating rod. Furthermore, a pressing handle is provided on the side wall of the handle near the end of the heating rod. The pressing handle is rotatably connected to the handle and is connected to the end of the clip near the handle. The clip has multiple guide holes arranged in an array to form a honeycomb structure.

[0008] Furthermore, the pressing handle includes a rotating shaft and a pressing shell, wherein the rotating shaft is rotatably connected to the end of the grip handle near the heating rod, the pressing shell is fixedly connected to the end of the clip near the grip handle, and the end of the pressing shell away from the heating rod extends upward and bends to form a pressing part; and, side plates are symmetrically arranged on both sides of the bottom of the pressing shell, the two side plates are respectively rotatably connected to the two ends of the rotating shaft, and a torsion spring is sleeved on the outside of the rotating shaft, one end of the torsion spring abuts against the grip handle and the other end of the torsion spring abuts against the pressing shell or the clip.

[0009] Furthermore, the grip includes a handle body, one end of which is fixedly connected to the heating rod. A rotation position is provided on one side of the end of the handle body connected to the heating rod. Support plates are symmetrically arranged on the rotation position. The two support plates are located inside adjacent side plates and are rotatably connected to both ends of the rotating shaft.

[0010] Furthermore, the torsion spring is a double torsion spring, comprising two spring bodies, one end of each spring body being connected to a torsion bar, and the other ends of the two spring bodies being connected by a torsion frame. A ball bearing is rotatably mounted on the torsion frame, wherein the ball bearing rolls in cooperation with the pressing shell or clamping plate, and the end of the torsion bar away from the spring body abuts against the grip handle.

[0011] Furthermore, the clip includes a clamping part, each of the flow guide holes is opened on the clamping part, the clamping part is located on the outside of the heating rod and the end of the clamping part near the handle is connected to the mounting part, the shape of the mounting part is adapted to the shape of the pressing shell and the mounting part is fitted and fixed to the inside of the pressing shell, and one end of the torsion spring abuts against the inner surface of the mounting part.

[0012] Furthermore, a limiting ring is fitted on one end of the handle near the heating rod, and a notch is opened on the limiting ring to form two opposing notch end faces, which respectively fit into the outer side surfaces of the two side plates.

[0013] Furthermore, the guide holes are diamond-shaped holes, and each guide hole is arranged symmetrically in two rows along the length of the clip.

[0014] Furthermore, the outer surface of the heating rod is provided with a graphene coating.

[0015] Due to the adoption of the above structure, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model features a clip with multiple airflow holes arranged in a honeycomb pattern. When the clip is used in conjunction with a heating rod to hold the hair, the clip effectively reduces the rate at which moisture is lost from the hair after being heated by the heating rod and forming steam. Furthermore, the steam flows out through the airflow holes, effectively preventing steam from accumulating between the clip and the heating element. In particular, it prevents excessively high local temperatures in the center of the clip and reduces the temperature difference between the center and the edge of the clip, thus achieving a balance between moisturizing and heat dissipation. The hot steam flowing out from the airflow holes forms a massaging airflow that surrounds and wraps around the hair strands, effectively improving the curl, elasticity, shine, and shaping effect of the hair.

[0017] 2. This utility model adopts a design in which the end of the pressing shell away from the heating rod extends upward and bends to form the pressing part, and one end of the torsion spring is fixedly engaged with the pressing shell or clip by a ball bearing, thereby effectively reducing frictional resistance and making pressing easier and less strenuous.

[0018] The present invention will become clearer from the following description and in conjunction with the accompanying drawings, which are used to explain the embodiments of the present invention. Attached Figure Description

[0019] To more clearly illustrate the technical solutions in the embodiments of this utility model, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0020] Figure 1 This is an exploded view of the structure of this utility model;

[0021] Figure 2 This is a schematic diagram of the overall structure of this utility model;

[0022] Figure 3 This is a schematic diagram of the torsion spring of this utility model. Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please refer to Figures 1 to 3 The curling iron provided by this utility model includes a handle 1, a heating rod 2, and a clip 3 that can fit against the outer surface of the heating rod 2. The handle 1 is provided with a controller and is connected to one end of the heating rod 2. The controller is electrically connected to the heating rod 2. Furthermore, a pressing handle 4 is provided on the side wall of the handle 1 near the end of the heating rod 2. The pressing handle 4 is rotatably connected to the handle 1 and is connected to the end of the clip 3 near the handle 1. Pressing the end of the pressing handle 4 away from the clip 3 can cause the end of the clip 3 away from the handle 1 to be lifted, thereby achieving the effect of opening and closing and clamping the hair. In addition, the clip 3 is provided with a plurality of guide holes 5, which are arranged in an array on the clip 3 to form a honeycomb structure. When the clip 3 and the heating rod 2 are used to clamp the hair, on the one hand, the clip 3 can effectively reduce the rate of moisture loss from the hair after it is heated by the heating rod 2 and forms steam. On the other hand, the steam flows out from the guide hole 5, which can effectively prevent steam from accumulating between the clip 3 and the heating part. In particular, it can prevent the local temperature in the middle of the clip 3 from becoming too high, reduce the occurrence of hair cuticle cracking under high temperature, and reduce the temperature difference between the middle and the edge of the clip 3, thereby achieving a balance between moisturizing and heat dissipation. Furthermore, the hot steam flowing out from the guide hole 5 can form a massage airflow that surrounds and wraps around the hair strands, effectively improving the curl, elasticity, shine, and shaping effect of the hair.

[0025] Optionally, the heating rod 2 is made of metal materials such as aluminum or titanium and is connected to a power source through a safe conductive wire. The controller includes a temperature sensor and a processing chip. The temperature sensor monitors the temperature of the heating rod 2 in real time and the processing chip adjusts the output power of the current in a timely manner, which can effectively reduce the temperature fluctuation of the heating rod 2 during use.

[0026] Optionally, the grip 1 has a built-in smart fuse chip for enhanced security.

[0027] Preferably, the chip is a dual-core or multi-core chip, which provides better computing and processing performance.

[0028] In this utility model, the pressing handle 4 includes a rotating shaft 41 and a pressing shell 42. The rotating shaft 41 is rotatably connected to the end of the grip handle 1 near the heating rod 2. The pressing shell 42 is fixedly connected to the end of the clip 3 near the grip handle 1, and the end of the pressing shell 42 away from the heating rod 2 extends upward and bends to form a pressing part 43, making pressing convenient and effortless. Furthermore, side plates 44 are symmetrically arranged on both sides of the bottom of the pressing shell 42. The two side plates 44 are rotatably connected to the two ends of the rotating shaft 41 respectively. A torsion spring 45 is sleeved on the outside of the rotating shaft 41. One end of the torsion spring 45 abuts against the grip handle 1, and the other end of the torsion spring 45 abuts against the pressing shell 42 or the clip 3.

[0029] The pressing shell 42 is bonded, fused, or integrally formed with the side plate 44. When the pressing part 43 is pressed down, the side plate 44 rotates around the pivot 41, and the pressing shell 42 causes the end of the clip 3 away from the handle 1 to be lifted up, so that the hair can be clamped between the clip 3 and the heating rod 2. At the same time, the torsion spring 45 is compressed and stores force. When the pressing part 43 is released, the torsion spring 45 returns to its original position and pushes the pressing part 43 to be lifted up, so that the end of the clip 3 away from the handle 1 is deflected downward until the hair is clamped and fixed by the clip 3 and the heating rod 2.

[0030] In this utility model, the grip 1 includes a handle body 11, one end of which is fixedly connected to the heating rod 2. A rotation position 12 is provided on one side of the end of the handle body 11 connected to the heating rod 2. Support plates 13 are symmetrically arranged on the rotation position 12. The two support plates 13 are respectively located inside the adjacent side plates 44 and are rotatably connected to both ends of the rotating shaft 41, thereby forming a lever structure. Pressing down on the pressing part 43 can cause the end of the clip 3 away from the grip 1 to lift up, so that the hair can be clamped between the clip 3 and the heating rod 2.

[0031] Please refer to Figure 3 The torsion spring 45 is a double torsion spring, comprising two spring bodies 451. One end of each spring body 451 is connected to a torsion bar 452, and the other ends of the two spring bodies 451 are connected by a torsion frame 453. A ball bearing 454 is rotatably mounted on the torsion frame 453. The ball bearing 454 rolls in cooperation with the pressing shell 42 or the clamping piece 3. The end of the torsion bar 452 away from the spring body 451 abuts against the grip handle 1, thereby effectively reducing the frictional resistance between the torsion spring 45 and the end in contact with the pressing shell 42 or the clamping piece 3, making pressing easier and less strenuous. Furthermore, the two torsion bars 452 symmetrically abut against both sides of the rotating position 12, resulting in better stability.

[0032] In this invention, the clamping piece 3 includes a clamping part 31, and each of the guide holes 5 is formed on the clamping part 31. The clamping part 31 is located on the outside of the heating rod 2, and an installation part 32 is connected to one end of the clamping part 31 near the handle 1. The shape of the installation part 32 is adapted to the shape of the pressing shell 42, and the installation part 32 is fitted and fixed to the inside of the pressing shell 42. One end of the torsion spring 45 abuts against the inner surface of the installation part 32. When the pressing part 43 is pressed, on the one hand, the pressing shell 42 provides further heat insulation, effectively preventing the heat generated by the heating rod 2 from being transmitted to the operator's fingers in sequence through the clamping part 31, the installation part 32, and the pressing shell 42; on the other hand, when the pressing part 43 is pressed, the downward force acts vertically on the installation part 32 through the pressing shell 42, which can better and more effortlessly open the clamping part 31.

[0033] Optionally, the mounting part 32 is fixedly connected to the pressing shell 42 by means of adhesive bonding, welding, screws, fasteners, etc.

[0034] Preferably, the heating rod 2 has a circular cross-section, and the clamping piece 3 has an arc-shaped cross-section, so that the clamping piece 3 can fit against the outer surface of the heating rod 2; the clamping part 31 and the mounting part 32 are integrally formed.

[0035] In this invention, a limiting ring 6 is fitted onto one end of the handle 11 near the heating rod 2. The limiting ring 6 has a notch 7 forming two opposing notch end faces, which respectively fit against the outer surfaces of the two side plates 44. This allows the lower end of the pressing handle 4 to extend into the rotating position 12 through the notch 7 for installation, and the two notch end faces limit the movement distance of the rotating shaft 41 in its axial direction, preventing the reel from dislodging.

[0036] Preferably, the outer diameter of the limiting ring 6 is larger than the outer diameter of the handle 1, which can effectively block the operator's hand and prevent the operator's hand from being burned when sliding to the heating rod 2 during hair curling.

[0037] In this invention, the guide hole 5 is a rhomboid hole, and each guide hole 5 is symmetrically arranged in two rows along the length of the clip 3, which can better guide the flow direction of the steam airflow, allowing the hot steam to wrap around the hair like a "massage airflow", increasing the steam shaping speed by 40%, increasing the curl, shaping power, elasticity and shine of the hair, and reducing problems such as frizz, burnt edges and frizz.

[0038] In this invention, the outer surface of the heating rod 2 is coated with graphene, which improves the heat conduction effect.

[0039] In use, this invention first heats the heating rod 2 to a preset temperature using a controller. Then, pressing down on the pressing part 43 causes the end of the clamping part 31 away from the handle 1 to tilt upwards via the pressing shell 42 and the clamping part 31. This opens the clip 3 and compresses the torsion spring 45. When hair enters between the clip 3 and the heating rod 2, releasing the pressing part 43 causes the torsion spring 45 to return to its original position and push the pressing part 43 upwards, causing the end of the clip 3 away from the handle 1 to deflect downwards until the hair is clamped between the clip 3 and the heating rod 2, thus fixing the hair in place. On the outer surface of the heating element 2, the wet hair is heated and curled, and the moisture on the hair is heated to form steam, which flows out from the guide hole 5. This effectively prevents steam from accumulating between the clip 3 and the heating part, especially preventing the local temperature in the middle of the clip 3 from becoming too high, reducing the possibility of hair cuticle cracking at high temperatures, and reducing the temperature difference between the middle and the edge of the clip 3, achieving a balance between moisturizing and heat dissipation. Furthermore, the hot steam flowing out from the guide hole 5 can form a massaging airflow that surrounds and wraps around the hair strands, effectively improving the curl, elasticity, shine, and shaping effect of the hair.

This does not affect the essential content of this utility model.
