Description

Technical Field

[0001] This utility model relates to the field of hair styling tools, and in particular to a hair curler with adjustable curling iron size. Background Technology

[0002] In modern society, personal image and beauty care are increasingly valued, and curling irons, as a common hair styling tool, are widely used in daily life. Most existing curling irons use a single-sized barrel, requiring users to select the appropriate diameter based on the desired curl size. However, this design has several drawbacks: First, the fixed-size barrel cannot meet users' needs for different curling effects. For example, some users may need a larger diameter barrel to create natural, voluminous waves, while others may prefer a smaller diameter barrel for tighter curls. This necessitates purchasing multiple barrels of different sizes, which is not only costly but also inconvenient to store. Second, to achieve different curl sizes, users need to frequently change barrels, increasing the number of steps and potentially causing inconvenience and wasted time. Third, the devices are bulky: to accommodate various size requirements, multi-functional curling irons on the market are usually complex in structure and large in size, making them difficult to carry and store. Utility Model Content

[0003] The purpose of this invention is to provide a hair curler with a simple structure, convenient operation, and adjustable curling size that can achieve multiple curling sizes.

[0004] To achieve the above objectives, this utility model provides a hair curler with adjustable curler size, which includes an operating handle and a heating head. The operating handle includes a first handle body and a second handle body. The first handle body includes a first end and a second end. The second handle body includes a third end and a fourth end. The first end and the third end are pivotally connected so that the second end and the fourth end can move closer to or further away from each other.

[0005] The heating head includes a bracket and a first wave groove and a second wave groove disposed on the bracket. The first wave groove and the second wave groove are located on different sides of the bracket, and the depths of the first wave groove and the second wave groove are different.

[0006] The fourth end is provided with a hair pressing rod adapted to the first wave groove and the second wave groove, the hair pressing rod being used to press the hair bundle into the first wave groove or the second wave groove;

[0007] The bracket is rotatably connected to the second end via a rotating structure. Based on this rotating structure, the bracket can rotate relative to the second end so that one of the first wave groove and the second wave groove is opposite to the pressure bar.

[0008] Preferably, when the support is rotated 180°, the positions of the first wave groove and the second wave groove are interchanged.

[0009] Preferably, the top of the bracket is provided with a rotating handle.

[0010] Preferably, the rotating structure includes a rotating shaft disposed at the second end of the first handle and a rotating sleeve disposed in the bracket that is adapted to the rotating shaft.

[0011] Preferably, the first handle body is further provided with a locking structure. When the locking structure is in the locked state, it restricts the relative rotation between the rotating sleeve and the rotating shaft. When the locking structure is in the unlocked state, the rotating sleeve and the rotating shaft can rotate freely.

[0012] Preferably, the locking structure includes two slots disposed at the edge of the rotating sleeve, a stop post adapted to the slots, a carrier, and a driving mechanism;

[0013] The stop post is disposed on the carrier frame, and the driving mechanism is used to drive the carrier frame to move along a preset trajectory so that the stop post enters or exits the slot; when the stop post enters one of the slots, the first wave groove is opposite to the pressure bar, and when the stop post enters the other slot, the second wave groove is opposite to the pressure bar.

[0014] Preferably, the driving mechanism includes an operating switch disposed on the outer shell of the first handle and connected to the carrier, and an elastic element disposed within the first handle. The operating switch is used to provide a driving force to the carrier to move in a first direction, causing the stop post to be dislodged from the slot. One end of the elastic element is connected to the carrier, and the other end of the elastic element is connected to a retaining wall disposed within the first handle. The elastic element is used to constantly provide a driving force to the carrier to move in a second direction, causing the stop post to enter the slot.

[0015] Preferably, the carrier is provided with a through hole, and the operating switch includes a base. One end of the base is provided with a pressing part located on the outer shell of the first handle, and the other end of the base is provided with a driving inclined surface extending into the through hole. The driving inclined surface abuts against the inner wall of one side of the through hole.

[0016] Preferably, lugs are provided on opposite sides of the base, and a limiting groove is provided in the second handle body, with the lugs slidably connected to the limiting groove.

[0017] Compared with existing technologies, the hair curler provided by the present invention features first and second wave grooves of different depths on different sides of the heating head bracket. The bracket is rotatably connected to the first handle. During curling, the bracket can be rotated to select one of the first and second wave grooves to work with the pressure bar. Therefore, the hair curler, by setting wave grooves of different depths and corresponding pressure bars, combined with a rotating structure, achieves the function of freely adjusting the curling size on a single device, realizing a multi-purpose effect. This not only improves operational efficiency and ease of use but also effectively reduces equipment size and production costs, demonstrating significant practical value and market potential.

[0028] To explain in detail the technical content, structural features, objectives and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0029] This embodiment discloses a hair curler for styling hair by curling it, that is, creating curls of a certain size. Figures 1 to 5 The curling iron includes an operating handle and a heating head. The operating handle includes a first handle body 10 and a second handle body 11. The first handle body 10 includes a first end 10a and a second end 10b. The second handle body 11 includes a third end 11a and a fourth end 11b. The first end 10a and the third end 11a are pivotally connected so that the second end 10b and the fourth end 11b can move closer to or further away from each other.

[0030] The heating head includes a bracket 20 and a first wave groove 21 and a second wave groove 22 disposed on the bracket 20. The first wave groove 21 and the second wave groove 22 are located on different sides of the bracket 20, and the groove depths of the first wave groove 21 and the second wave groove 22 are different.

[0031] The fourth end 11b is provided with a hair pressing rod 3 that is adapted to the first wave groove 21 and the second wave groove 22. The hair pressing rod 3 is used to press the hair bundle into the first wave groove 21 or the second wave groove 22.

[0032] The bracket 20 is rotatably connected to the second end 10b via a rotating structure. Based on this rotating structure, the bracket 20 can rotate relative to the second end 10b so that one of the first wave groove 21 and the second wave groove 22 is opposite to the pressure rod 3.

[0033] Specifically, the depth of the first wave groove 21 is smaller than that of the second wave groove 22. When using this curling iron to curl hair, firstly, the relative pivoting motion between the first handle 10 and the second handle 11 is operated to move the first handle 10 and the second handle 11 away, thereby separating the curling iron 3 from the support 20 (e.g., Figure 2 ).

[0034] Then, if the first wave groove 21 is currently opposite the pressure bar 3, and the user needs to use the second wave groove 22 with a larger groove depth to make larger hair curls, the bracket 20 is rotated so that the second wave groove 22 is opposite the pressure bar 3.

[0035] Next, place the hair strand in the second wave groove 22.

[0036] Then, the relative pivoting motion between the first handle 10 and the second handle 11 is operated again to bring the first handle 10 and the second handle 11 closer together (e.g., Figure 1 The hair curler 3 is pressed into the second wave groove 22, pressing the hair strand between the second wave groove 22 and the hair curler 3, causing the hair strand to curl and deform. The deformed hair strand is then shaped by heating the second wave groove 22.

[0037] This hair curler, with its aforementioned structure, incorporates wave grooves of varying depths and corresponding pressure rollers 3, along with a rotating mechanism, enabling free adjustment of curl size on a single device and achieving multi-functionality. This not only improves operational efficiency and ease of use but also effectively reduces device size and production costs, demonstrating significant practical value and market potential.

[0038] On the other hand, when the support 20 rotates 180°, the positions of the first wave groove 21 and the second wave groove 22 are interchanged. That is, the first wave groove 21 and the second wave groove 22 are located on the front and back sides of the support 20 respectively, so that the two do not affect each other.

[0039] like Figure 3 The top of the bracket 20 is provided with a rotating handle 23, which can be used to rotate the bracket 20, making it convenient to use.

[0040] like Figure 6 The rotating structure includes a rotating shaft 40 disposed at the second end 10b of the first handle 10 and a rotating sleeve 41 disposed in the bracket 20 and adapted to the rotating shaft 40. The rotating shaft 40 is inserted into the rotating sleeve 41. When a rotational torque is applied to the bracket 20, the rotating sleeve 41 rotates relative to the rotating shaft 40, thereby causing the bracket 20 to rotate.

[0041] Furthermore, the rotating sleeve 41 is detachably connected to the rotating shaft 40, so that multiple supports 20 can be configured for the first handle 10. The groove depths of the wave grooves on the multiple supports 20 are different, which can increase the user's choice of hair curl size.

[0042] Furthermore, to ensure the support 20 remains stable in its current position during curling and to prevent the hair strands from being pulled, a locking structure is also provided inside the first handle 10. When the locking structure is in the locked state, it restricts the relative rotation between the rotating sleeve 41 and the rotating shaft 40. When the locking structure is in the unlocked state, the rotating sleeve 41 and the rotating shaft 40 can rotate freely.

[0043] Specifically, such as Figures 6 to 8 The locking structure includes two slots 410 located at the edge of the rotating sleeve 41, a stop post 51 adapted to the slots 410, a carrier 50, and a driving mechanism. In this embodiment, the two slots 410 are located on opposite sides of the center point of the rotating sleeve 41.

[0044] A stop post 51 is mounted on the carrier 50. A drive mechanism is used to drive the carrier 50 to move along a preset trajectory, so that the stop post 51 enters or exits the slot 410. When the stop post 51 enters the slot 410, it restricts the rotation of the rotating sleeve 41 to lock the bracket 20. When the stop post 51 exits the slot 410, the rotating sleeve 41 can rotate freely.

[0045] In addition, when the stop post 51 enters one of the slots 410, the first wave groove 21 is opposite to the pressure bar 3, and when the stop post 51 enters the other slot 410, the second wave groove 22 is opposite to the pressure bar 3.

[0046] like Figures 5 to 10 On the other hand, the drive mechanism includes an operating switch 6 connected to the carrier 50 and disposed on the outer shell of the first handle 10, and an elastic element 7 disposed within the first handle 10. The operating switch 6 is used to provide a driving force for the carrier 50 to move in a first direction, causing the stop post 51 to be dislodged from the slot 410. One end of the elastic element 7 is connected to the carrier 50, and the other end of the elastic element 7 is connected to the retaining wall 13 disposed within the first handle 10. The elastic element 7 is used to constantly provide a driving force for the carrier 50 to move in a second direction, causing the stop post 51 to enter the slot 410.

[0047] In this embodiment, by operating the switch 6, the carrier 50 can be driven to move the stop post 51 away from the rotating sleeve 41. When the driving force from the user on the operating switch 6 disappears, under the elastic restoring force of the elastic element 7, the carrier 50 drives the stop post 51 to move closer to the rotating sleeve 41 and enter the slot 410.

[0048] Specifically, the carrier 50 is provided with a through hole 500, and the operating switch 6 includes a base 60. One end of the base 60 is provided with a pressing part 61 located on the outer shell of the first handle 10, and the other end of the base 60 is provided with a driving inclined surface 62 extending into the through hole 500. The driving inclined surface 62 abuts against the inner wall on one side of the through hole 500.

[0049] In this embodiment, when the user applies pressure to the pressing part 61, the driving inclined surface 62 moves in the direction of passing through the through hole 500, thereby driving the bracket 20 to move away from the rotating sleeve 41.

[0050] On the other hand, lugs 63 are provided on opposite sides of the base 60, and a limiting groove 12 is provided inside the second handle 11. The lugs 63 and the limiting groove 12 are slidably connected. By providing the lugs 63 and the limiting groove 12, the base 60 can move up and down in a specified direction to improve the stability of the operating switch 6.

[0051] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the scope of the present utility model application shall still fall within the scope of the present utility model.
