Description

Technical Field

[0001] This invention relates to the field of hair curling tools, and more particularly to a hair curler with adjustable curl size. Background Technology

[0002] Hair curling tools are used to create curly hairstyles and come in various types. Common ones include curling irons, which heat up quickly, allow for temperature adjustment, and can create different curl shapes. They are easy to use, and some are made of ceramic to reduce hair damage. Automatic curling irons are more intelligent; simply place your hair in the iron and press a switch to automatically curl it, saving time and effort.

[0003] Most electric curling irons on the market have a relatively simple structure, mainly consisting of the curling iron itself, heating element, temperature controller, handle, and power cord. The heating element is mostly made of ceramic or metal, which can quickly and evenly generate heat to style the hair; the temperature controller is used to control the temperature and prevent hair from being damaged by overheating, and some products are also equipped with intelligent temperature control systems; the handle is made of high-temperature resistant insulating material to ensure safe use and often has an anti-slip design; the power cord connects the curling iron to the power source, and some are designed to be retractable or 360° rotating for easy operation.

[0004] In reality, the effect of hair curls is affected by a variety of factors. Among them, the diameter of the curling iron directly determines the size of the curl. For example, a small diameter curling iron is suitable for creating tight small curls, while a large diameter curling iron is suitable for creating natural large waves. The shape of the curling iron directly determines the overall effect of the hair curls. For example, a cylindrical curling iron produces hair curls with uniform curls and the same diameter from root to tip, forming regular spiral curls. A conical curling iron produces curls with the curl gradually becoming lighter from the roots to the tips, forming naturally transitioning layered curls. By changing the direction, tilt, or rotation of the curling iron, the shape, direction, volume, and layering of the hair curls can be significantly affected, thus creating a variety of curl effects. However, most electric curling irons on the market are fixed and cannot achieve the above effects. Therefore, a curling iron with adjustable curl size is proposed. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing hair curlers, such as poor adjustability and limited curling effect, by proposing a hair curler with adjustable curling size.

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

[0007] An adjustable curling iron includes a curling shell and symmetrically arranged angled curling irons. The curling shell is provided with a spacing adjustment component, which includes a drive adjustment disc. The drive adjustment disc is symmetrically arranged with equidistant and rotatable bases. A rotatable support platform is provided on the top of the base. The angled curling irons are mounted on the support platform, and the angle of the angled curling irons is adjustable. The rotation of the two support platforms can realize the overall shape change of the combination of the two angled curling irons. The adjustable spacing of the bases can realize the overall size change of the combination of the two angled curling irons. A detachable adjustment plate is provided between the two angled curling irons.

[0008] A limiting component is provided between the support platform and the base. The limiting component is used to limit and engage the two inclined curling irons after adjusting their shape.

[0009] The bottom of the drive adjustment disc is provided with a drive component, which is used to control the two angled curling irons to rotate in different directions.

[0010] The above technical solution further includes:

[0011] The adjustment assembly also includes a limit plate rotatably connected to the bottom of the drive adjustment plate. The drive adjustment plate is rotatably connected to the hair curling shell. The limit plate is rotatably connected to the inner side of the top of the hair curling shell. The limit plate has multiple fastening threaded holes. Fastening bolts are threadedly connected between the fastening threaded holes and the drive adjustment plate.

[0012] An adjustment handle is fixedly connected to the outer side of the drive adjustment disc. Multiple drive grooves are formed through the circumferential array on the drive adjustment disc. Multiple limit grooves are formed through the circumferential array on the limit disc. A slide is slidably arranged between the drive grooves and the limit grooves. An adjustable pressure plate is rotatably connected to two of the slides, and a fixed pressure plate is fixedly connected to the other two slides.

[0013] The inner sides of the drive adjustment plate and the limit plate are fixedly connected to a support plate. The support plate is symmetrically provided with main adjustment slots. The base is rotatably disposed in the main adjustment slots. The support platform is rotatably disposed on the base. An adjustable tension bolt is provided between the support platform and the angled curling iron. Heating rods are installed inside the two angled curling irons. The cross-section of the two angled curling irons is a right trapezoid.

[0014] The support platform has a traction slot on its outer side, the angled curling iron has a circular universal groove, the adjustable pressure plate and the angled curling iron are rotatably connected by a universal rod, the slide table is fixedly connected to a traction rod on the side near the base, the traction slot and the traction rod engage and slide together, and both the traction slot and the circular universal groove are through grooves opened around the circumference.

[0015] The limiting component also includes a limiting slot formed at the bottom of the support platform. Multiple limiting springs are installed in a circular array on the inner side of the base. A limiting bead is fixedly connected to one end of the limiting spring near the support platform. The limiting bead is rolled and engaged in the limiting slot.

[0016] The drive assembly also includes a drive flywheel rod installed at the center of the base. The base is rotatably connected to the support platform. The support plate is also symmetrically provided with adjustable grooves. The drive flywheel rod rolls relative to the adjustable grooves.

[0017] The bottom of the support plate is symmetrically provided with tightening grooves, and a tightening spring is installed in the tightening groove. A tightening flywheel rod that is fixedly connected to the tightening spring is slidably arranged in the tightening groove. An installation cylinder is fixedly connected inside the curling shell, and a motor is installed on the bottom inner side of the installation cylinder.

[0018] The bottom of the support plate is symmetrically rotatably connected to a fixed flywheel rod. The outer side of each fixed flywheel rod is fixedly connected to a directional gear. The two directional gears mesh with each other. The output end of the motor is fixedly connected to one of the fixed flywheel rods. A transmission belt is sleeved and connected to the fixed flywheel rod, the tensioning flywheel rod, and the drive flywheel rod.

[0019] A micro motor is also fixedly connected inside the curling shell. The output end of the micro motor is fixedly connected to the mounting cylinder, and the mounting cylinder is fixedly connected to the limiting plate.

[0020] The present invention has the following beneficial effects:

[0021] 1. In this invention, when the two slanted curling irons are placed close together at right angles, the whole structure forms a cone shape. The spacing and angle between them can be changed by adjusting the components to create curls of different sizes and layers. The orientation of their slanted surfaces can also be adjusted individually to create different shapes, thereby creating more novel hairstyles. Moreover, the close proximity of the right angles of the two slanted curling irons also has the function of straightening the hair. This design is more suitable for the needs of different people.

[0022] 2. In this invention, when the angled surfaces of the two angled curling irons are placed close together, the overall shape is cylindrical. By adjusting the distance between the two angled curling irons, the overall cylindrical shape of the two angled curling irons can be enlarged or reduced, thereby creating large waves or wool curls. In addition, the two angled curling irons can rotate in opposite directions independently, achieving a variety of curling styles. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] like Figures 1-9As shown, the present invention proposes an adjustable curling iron, including a curling shell 1 and symmetrically arranged oblique curling irons 4. The curling shell 1 is provided with a spacing adjustment component, which includes a drive adjustment disk 2. The drive adjustment disk 2 is symmetrically arranged with equidistant and rotatable bases 43. The top of the bases 43 is provided with a rotatable support platform 42. The oblique curling irons 4 are mounted on the support platform 42, and the angle of the oblique curling irons 4 is adjustable. The rotation of the two support platforms 42 can realize the shape change of the two oblique curling irons 4 as a whole. The adjustable spacing of the bases 43 can realize the size of the two oblique curling irons 4 as a whole. A detachable adjustment plate 41 is provided between the two oblique curling irons 4.

[0035] Furthermore, the two angled curling irons 4 are designed as angled cylinders with right-angled trapezoidal cross-sections. Therefore, there are multiple ways to combine them when adjusting their positions: when the two right-angled surfaces are in contact, the two angled curling irons 4 combine to form a cone; when the two angled surfaces are close to each other, the two angled curling irons 4 form a cylinder; when the angled surfaces of the two angled curling irons 4 face the fixed pressure plate 3, the two angled curling irons 4 form a quadrilateral-like shape.

[0036] Furthermore, the adjustment component is mainly used to adjust the distance between the two angled curling irons 4. The angle of the two angled curling irons 4 on the support platform 42 is adjustable. During the adjustment process, firstly, the adjustment plate 41 is inserted into the two angled curling irons 4, then the tension bolt 411 is loosened, and the distance between the two support platforms 42 is adjusted by adjusting the handle 23. Since the tops of the two angled curling irons 4 are temporarily fixed, the change in the distance between the support platforms 42 causes the included angle between the two angled curling irons 4 to change. After the adjustment is completed, the tension bolt 411 is tightened. The adjustment plate 41 can be selectively removed according to one's own needs, and then curling can be performed. Alternatively, the tension bolt 411 can be removed without loosening it, and the distance between the two support platforms 42 can be adjusted to make the overall size formed by the two angled curling irons 4 larger or smaller, thereby realizing the change in the size of the curling irons.

[0037] Furthermore, this design offers a variety of curling methods. First, by controlling the rotation of the micro motor 10 and using the symmetrically arranged adjustable pressure plates 5 to restrict the hair, the hair can be rolled around the outside of the two angled curling irons 4. Alternatively, the hair can be rolled around a single angled curling iron 4 for curling, or the hair can be placed between the vertical surfaces of the two angled curling irons 4 for straightening.

[0038] A limiting component is provided between the support platform 42 and the base 43. The limiting component is used to limit and lock the two inclined curling irons 4 after adjusting their shape.

[0039] Furthermore, the limiting component is used to limit and engage the individual angled curling iron 4 after it has rotated.

[0040] The bottom of the drive adjustment plate 2 is equipped with a drive component, which is used to control the two angled curling irons 4 to rotate in different directions.

[0041] The adjustment assembly also includes a limit plate 20 rotatably connected to the bottom of the drive adjustment plate 2. The drive adjustment plate 2 is rotatably connected to the hair curling shell 1. The limit plate 20 is fixedly connected to the inner side of the top of the hair curling shell 1. The limit plate 20 is provided with multiple fastening threaded holes 25. Fastening bolts 22 are threadedly connected between the fastening threaded holes 25 and the drive adjustment plate 2.

[0042] An adjustment handle 23 is fixedly connected to the outer side of the drive adjustment plate 2. Multiple drive grooves 21 are opened through the circumferential array on the drive adjustment plate 2. Multiple limit grooves 27 are opened through the circumferential array on the limit plate 20. A slide table 50 is slidably arranged between the drive grooves 21 and the limit grooves 27. Two slide tables 50 are rotatably connected to adjustable pressure plates 5, and two other slide tables 50 are fixedly connected to fixed pressure plates 3.

[0043] Furthermore, by rotating the adjustment handle 23, the adjustment handle 23 rotates the drive 2 along its central axis. Subsequently, the slide table 50 moves along the guide of the limit groove 27 under the driving action of the drive groove 21 and the limiting action of the limit groove 27. At the same time, it moves under the action of the traction rod 52 set between the slide table 50 and the support table 42, thereby realizing the adjustment of the distance between the two inclined curling irons 4.

[0044] The inner sides of the drive adjustment plate 2 and the limit plate 20 are fixedly connected to the support plate 24. The support plate 24 is symmetrically provided with the main adjustment groove 26. The base 43 is rotatably disposed in the main adjustment groove 26. The support platform 42 is rotatably disposed on the base 43. An adjustable tension bolt 411 is provided between the support platform 42 and the inclined curling iron 4. Heating rods 40 are installed inside the two inclined curling irons 4. The front view cross section of the two 4s is a right trapezoid.

[0045] Furthermore, when the traction rod 52 pulls the base 43 to slide within the main adjustment groove 26, the main adjustment groove 26 is set in the shape of a dovetail groove, and the base 43 is a cylindrical truncated block, which can be adjusted by loosening or tightening the bolt 411 when rotating in the main adjustment groove 26 and adjusting the angle between the angled curling irons 4.

[0046] Furthermore, the adjustable angled curling iron 4 is equipped with a heating rod 40, the temperature of which is adjustable to maintain the shape of the curl during the curling process.

[0047] The support platform 42 has a traction slot 45 on its outer side, and the inclined curling iron 4 has a circular universal groove 44. The adjustable pressure plate 5 and the inclined curling iron 4 are rotatably connected by a universal rod 51. The slide table 50 is fixedly connected to the side near the base 43 with a traction rod 52. The traction slot 45 and the traction rod 52 engage and slide together. Both the traction slot 45 and the circular universal groove 44 are through grooves opened around the circumference.

[0048] Furthermore, the design of the traction slot 45 allows the traction base 43 to move synchronously with the slide table 50 without affecting the rotation of the traction base 43. The design of the circular universal groove 44 ensures that the adjustable pressure plate 5 remains parallel to the side opposite to the angled curling iron 4 during the angle adjustment process.

[0049] The limiting component also includes a limiting slot 48 opened at the bottom of the support platform 42. Multiple limiting springs 46 are installed in a circular array on the inner side of the base 43. A limiting bead 47 is fixedly connected to one end of the limiting spring 46 near the support platform 42. The limiting bead 47 is rolled and engaged in the limiting slot 48.

[0050] Furthermore, since the circular universal groove 44 is designed to be shallower on the angled curling iron 4, specifically, the closer to the right angle, the shallower the circular universal groove 44 is. When rotating a single angled curling iron 4 to adjust the shape of the entire angled curling iron, the limiting spring 46 is used to push the limiting bead 47 into the limiting slot 48. Each time the support platform 42 is rotated at a certain angle, the limiting bead 47 can be engaged once.

[0051] The drive assembly also includes a drive flywheel rod 49 installed at the center of the base 43. The base 43 is rotatably connected to the support platform 42. The support plate 24 is also symmetrically provided with a follower adjustment groove 410. The drive flywheel rod 49 and the follower adjustment groove 410 roll relative to each other.

[0052] Furthermore, during the adjustment of the position of the base 43, the drive flywheel rod 49, which is fixedly connected inside it, will move synchronously within the adjustment groove 410.

[0053] The bottom of the support plate 24 is symmetrically provided with a tightening groove 64, a tightening spring 65 is installed in the tightening groove 64, a tightening flywheel rod 66 is slidably arranged in the tightening groove 64 and fixedly connected to the tightening spring 65, and an installation cylinder 11 is fixedly connected inside the hair curling shell 1, and a motor 6 is installed on the bottom inner side of the installation cylinder 11.

[0054] Furthermore, when the position of the drive flywheel lever 49 changes, the tension of the belt 63 will change. In order to ensure the stability of power transmission, the tensioning spring 65 in the tensioning groove 64 is fixedly connected. The tensioning spring 65 continuously applies elastic pressure to tighten the flywheel lever 66, so that the tensioning flywheel lever 66 always keeps in close contact with the belt 63, thus ensuring the stability of power transmission.

[0055] The bottom of the support plate 24 is symmetrically rotatably connected to a fixed flywheel rod 61. The outer side of each fixed flywheel rod 61 is fixedly connected to a directional gear 62. The two directional gears 62 mesh with each other. The output end of the motor 6 is fixedly connected to one of the fixed flywheel rods 61. A transmission belt 63 is sleeved and connected between the fixed flywheel rod 61, the tightening flywheel rod 66, and the driving flywheel rod 49.

[0056] The interior of the curling shell 1 is also fixedly connected to a micro motor 10. The output end of the micro motor 10 is fixedly connected to the mounting tube 11, and the mounting tube 11 is fixedly connected to the limiting plate 24.

[0057] In this embodiment, two rotatable curling modes are available. When the micro motor 10 is started, it drives the mounting cylinder 11 to rotate synchronously through a fixed connection. Since the mounting cylinder 11 is fixedly connected to the limiting plate 20, it drives the limiting plate 20 and the overall structure to rotate around the axis of the micro motor 10, providing basic rotational power for the curling iron. Specifically, after the position and angle of the angled curling iron 4 are adjusted, the drive adjustment plate 2 and the limiting plate 20 are fixed together by the fastening bolt 22. Since 24 is fixedly set between the drive adjustment plate 2 and the limiting plate 20, the components above the limiting plate 20 will rotate synchronously during the rotation of the limiting plate 20, clamping the hair between the two angled curling irons 4. The rotation of the micro motor 10 drives the fixed pressure plate and the adjustable pressure plate to work together to achieve the curling function.

[0058] Meanwhile, another method of curling hair is as follows: the micro motor 10 stops rotating, and the motor 6 serves as an auxiliary power source. Its output end is fixedly connected to one of the fixed flywheel rods 61 symmetrically arranged at the bottom of the support plate 24. When the motor 6 starts, the fixed flywheel rod 61 begins to rotate and is driven by the meshing of the directional gear 62 fixed on the outside with the directional gear 62 of the other fixed flywheel rod 61, so as to realize the synchronous reverse rotation of the two fixed flywheel rods 61. Then, the power is transmitted to the tightening flywheel rod 66 and the driving flywheel rod 49 through the transmission belt 63.

[0059] The tightening flywheel rod 66 is slidably disposed in the tightening groove 64 at the bottom of the support plate 24 and is fixedly connected to the tightening spring 65 in the tightening groove 64. The tightening spring 65 applies elastic pressure to keep the tightening flywheel rod 66 in close contact with the belt 63 at all times, so as to ensure the stability of power transmission.

[0060] The drive flywheel lever 49 is fixedly connected to the center of the inner side of the base 43. The rotation of the drive flywheel lever 49 can drive the angled curling iron 4 to rotate. The two angled curling irons 4 rotate in different directions. At this time, hair can be rolled on the angled curling iron 4 to create two curls with opposite spiral directions.

[0061] This design allows for multi-dimensional adjustments to the spacing, angle, and overall rotation of the curling iron, satisfying diverse needs for curling styles.

[0062] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
