Description

Technical Field

[0001] The utility model belongs to the technical field of hair curlers, in particular to a hair curler structure. Background Art

[0002] Hair curling is typically done by heating and shaping the hair using a curling iron. Current curling irons typically consist of a curling rod and a curling clamp. To curl hair, the operator wraps hair around the curling rod, heating and shaping the hair. Once the hair cools, it becomes curled. For example, Chinese patent publication CN218418787U discloses a curling iron with an interchangeable head. While the curling iron is replaceable, the hair still needs to be manually wrapped around the iron during the curling process.

[0003] When curling hair, a curling iron clamps the hair using a plate. The curling iron is then rotated to wrap the hair around the plate. The hair is then pulled downward along the ends of the hair, heating it and curling it. For example, Chinese patent publication CN216123959U discloses a hair straightener and curling iron structure comprising a lower plate assembly, an upper plate assembly, and a control circuit board. The lower plate assembly comprises a lower plate, a lower heating plate assembly, and a blower, while the upper plate assembly comprises an upper plate and an upper heating plate assembly. When curling is required, the upper and lower clamping plates clamp the hair, and the hair straightener is rotated so that the hair is wrapped around the first air outlet and the second air outlet, and then the hair is pulled toward the end of the hair. During the hair pulling process, the fan draws outside air into the first cavity. Under the action of the air guide, the flowing air enters the cavity of the upper clamping plate, and then the first air outlet and the second air outlet blow air toward the hair, so that the hair is quickly cooled and shaped, thereby completing the hair curling. Therefore, the air-cooled hair straightener can achieve the functions of straightening and curling hair, meeting the needs of users.

[0004] The technical solutions disclosed in the aforementioned patent documents are cumbersome to operate, especially when curling your own hair. Curling with a curling iron results in large curls, and smaller curls require a smaller iron. Curling irons with both straightening and curling functions typically only produce inward or outward curls at the ends of the hair. Utility Model Content

For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium; internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on specific circumstances.

[0035] In one embodiment of the hair curler structure of the present invention, please refer to Figure 1 , Figure 2 , Figures 6 to 8 , a hair curler structure for heating and curling hair. Specifically, it includes a first clamping plate 100 and a second clamping plate 200 that can be rotated to open, and each of the first clamping plate 100 and the second clamping plate 200 is provided with an electric heating element (not shown in the drawings). The structure, installation method and heating principle of the electric heating element are conventional technologies in the field and will not be described in detail in this embodiment. The first clamping plate 100 is provided with a first clamping surface 101, and the second clamping plate 200 is provided with a second clamping surface 201. The first clamping surface 101 and the second clamping surface 200 are both provided with multiple rows of forming teeth 300, which are staggered and arranged, and the interlocking forming teeth 300 form a curling position 301. The tooth top 302 of the forming tooth 300 is an outer arc surface, and the first clamping surface 101 and the second clamping surface 201 are provided with inner arc surfaces 102, 202 that match the tooth top 302 of the corresponding forming tooth 300. When curling hair, this hair curler structure allows you to pull out the hair one by one. The first and second clamping plates 100 and 200 clamp the pulled-out hair, and the shaped teeth 300 on the first and second clamping surfaces 101 and 201 form a curling position 301 to clamp the hair, creating a wavy curvature. The clamping method using the first and second clamping plates 100 and 200 makes operation more convenient. Furthermore, users can selectively heat and shape the hair at certain locations, such as the ends, to avoid a single curl and customize the curl to their needs. Furthermore, the tooth tips 302 of the curling teeth 300, which mate with the first and second clamping surfaces 101 and 201, are formed as outer and inner arcs, respectively. This allows the hair to be bent smoothly when clamped, providing a certain degree of protection.

[0036] Further, referring to Figure 2 , when the first clamping plate 100 and the second clamping plate 200 are clamped, there is a gap 303 for clamping hair between the tooth crest 302 and the corresponding inner arc surfaces 102, 202. In this embodiment, when clamping hair, it is avoided that the tooth crest 302 of the forming teeth 300 clamps the hair too tightly and damages the hair, achieving a good protective effect on the hair.

[0037] Further, please refer to Figures 1 to 8 , the hair curling clip structure of this embodiment further includes a third clamping plate 400, and the second clamping plate 200 is rotatably connected to the third clamping plate 400. The second clamping plate 200 is further provided with a fourth clamping surface 203, the third clamping plate 400 is provided with a third clamping surface 401, and an electric heating element is provided inside the third clamping plate 400. In this embodiment, the third clamping surface 401 and the fourth clamping surface 203 can be used to cooperate to clamp hair, realizing the straightening or curling of hair, and thus realizing multi-functional curling.

[0038] Still further, please refer to Figure 2 , Figure 3 and Figure 5 , the third clamping surface 401 and the fourth clamping surface 203 are arc surfaces that are mutually clamped. Among them, the third clamping surface 401 is an inwardly concave inner arc groove surface, and the fourth clamping surface 203 is an outer arc surface. Using the inner arc surface and the outer arc surface to cooperate to clamp hair can not only increase the curling effect, make the hair curl inward more smoothly and with a better effect, but also increase the contact area with the hair, thereby increasing the clamping force on the hair and clamping the hair more tightly, so that the hair is heated more evenly.

[0039] Further, referring to Figures 2 to 4 , the third clamping plate 400 includes a handle shell 410 and a heat conducting plate 420. An installation cavity 411 is provided inside the handle shell 410, and a control circuit 500 is arranged in the installation cavity 411. One end of the handle shell 410 extends with an installation part 412, the installation part 412 is provided with an installation groove 413, the heat conducting plate 420 is arranged in the installation groove 413, and an electric heating element is provided inside the heat conducting plate 420. The third clamping surface 401 is arranged on the heat conducting plate 420. A connecting part 413 is provided at one end of the installation part 412 close to the handle shell 410, and the second clamping plate 200 is rotatably connected to the connecting part 413.

[0040] Still further, referring to Figure 2 , an elastic support member 414 is further provided in the installation groove 413, and the heat conducting plate 420 is supported on the elastic support member 414, so that the heat conducting plate 420 can sink towards the bottom side of the installation groove 413. Therefore, by moving the heat conducting plate 420 up and down, the pulling force of the hair is adjusted, avoiding excessive pulling force and damaging or breaking the hair.

[0041] Further, referring toFigure 4 , Figure 5 , Figure 8 and Figure 9 , a self-locking structure 430 is further provided in the handle housing 410, and the self-locking structure 430 is used to alternately limit the first clamping plate 100 and the second clamping plate 200 to open. Specifically, when the shaping teeth 300 are needed to curl the hair, the second clamping plate 200 and the third clamping plate 400 can be locked together, and the first clamping plate 100 can be freely opened to realize the function of clamping the hair with the second clamping plate 200 to curl the hair. When it is necessary to use the third clamping surface 401 and the fourth clamping surface 203 to clamp the hair for shaping, the first clamping plate 100 and the second clamping plate 200 are locked together by the self-locking structure 430, so that the whole formed by the second clamping plate 200 and the first clamping plate 100 can be freely opened.

[0042] A specific embodiment in which the self-locking structure 430 realizes the self-locking of the first clamping plate 100 and the second clamping plate 200. Specifically, referring to Figure 4 , Figure 5 , Figure 8 and Figure 9 , one end of the first clamping plate 100 extends with a first mounting plate 110, one end of the second clamping plate 200 is provided with a second mounting plate 210, and a rotating shaft 600 passes through the connecting portion 413, the first mounting plate 110 and the second mounting plate 210, so that the first clamping plate 100 and the second clamping plate 200 can rotate freely relative to the third clamping plate 400. More specifically, there are two groups of the first mounting plate 110, the second mounting plate 210, and the connecting portion 413, and they are oppositely arranged, so as to increase the connection stability between the first clamping plate 100 and the second clamping plate 200 and the third clamping plate 400. The first mounting plate 110 is provided with a first limiting groove, and the second mounting plate 210 is provided with a second limiting groove 211. Among them, the first limiting groove includes a first guiding groove 111 and a clamping groove 112, and the clamping groove 112 is provided on one side at the bottom end of the first guiding groove 111. One end of the second limiting groove 211 overlaps with the lower end of the first guiding groove 111, and the other end overlaps with the clamping groove 112; among them,

[0043] Please refer to Figure 5 , Figure 8 and Figure 9The self-locking structure 430 includes a slider 431, a stopper 432, and a stopper shaft 433. The slider 431 is slidably connected to the handle housing 410. The stopper 432 limits the slider 431, allowing it to slide in only one direction. The bottom side of the slider 431 is provided with a toggle portion 434 that extends out of the handle housing 410. The slider 431 is extended with a push plate 435. The push plate 435 is provided with a second guide groove 436, which runs through the top side of the push plate 435. The stopper shaft 433 passes through the first stopper groove 211, the second stopper groove 436, and the second guide groove 436. Specifically, when the first splint 100 needs to be opened freely and the second splint 200 and the third splint 400 are fixed as one, the slider 431 is driven to slide by pushing the toggle portion 434, and the push plate 435 on the slider pushes the limit shaft 433 to move to the bottom end of the first guide groove 111. When the first splint 100 is opened, the first splint 100 rotates around the rotating shaft 600, and the first guide groove 111 avoids the limit shaft 433, so that the first mounting plate 110 can swing downward, thereby realizing that the first splint 100 can be rotated around the rotating shaft 600 to open. When the second clamping plate 200 is opened, the slider 431 can be pushed backward by the toggle portion 434, and the push plate 435 on the slider 431 pushes the limit shaft 433 to move, so that the limit shaft 433 is located in the slot 112. Therefore, when the second clamping plate 200 is opened, the first clamping plate 100 is pressed, causing the first mounting plate 100 to rotate about the rotation axis 600. When the first mounting plate 100 rotates, the top side of the slot 112 pushes the limit shaft 433 to rotate downward. The downward rotation of the limit shaft 433 pushes the second mounting plate 210 to rotate together, so that the second clamping plate 200 and the first clamping plate 100 are integrated and rotated together to open.

[0044] Further, refer to Figure 8 The slider 431 is further provided with a support plate 437. When the limiting shaft 433 is pushed into the slot 112, the support plate 437 is supported on the bottom side of the second mounting plate 210. This achieves the purpose of limiting the position of the second mounting plate 210. The second clamping plate 200 cannot be rotated open, and only the first clamping plate 100 can be freely opened to clamp and shape the hair curlers.

[0045] Further, refer to Figure 4 , Figure 5 and Figure 8 A pressing portion 120 is extended upward from one end of the first splint 100, and a compression spring 130 is provided between the bottom side of the pressing portion 120 and the handle shell 400. The compression spring 130 is used to push the pressing portion 120 upward to clamp the first splint 100 and the second splint 200 or the second splint 200 and the third splint 400.

[0046] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
