[0037] The invention provides a hair curling mechanism.

[0038] See also Figure 3 , Figure 4 In one embodiment of the present invention, the curling mechanism comprises:

[0039] The first heat-conducting member 100 has a first contact surface 110, and in the present application, the first contact surface 110 should be understood as a complete surface; and the second heat-conducting member 200 has a second contact surface 220 arranged facing the first contact surface 110, wherein the second contact surface 220 should be understood as a complete surface, wherein the first contact surface 110 and the second contact surface 220 are both heat-conducting surfaces; a cavity 300 for receiving hair can be formed between the first contact surface 110 and the second contact surface 220; the curling mechanism has a closed state and an open state. state; in the closed state, a wavy cavity 300 is formed between the first contact surface 110 and the second contact surface 220. Since the first contact surface 110 and the second contact surface 220 are both complete surfaces, the wavy cavity 300 formed at this time is also complete, that is, there is no gap in the cavity 300. At this time, the hair is set in the cavity 300 and can be clamped by the first contact surface 110 and the second contact surface 220; it is prevented that part of the hair escapes from the cavity 300, that is, it is prevented that part of the hair escapes from the gap in the cavity 300. At the same time, in the closed state, when there is no hair between the first contact surface 110 and the second contact surface 220, at least part of the first contact surface 110 and the second contact surface 220 are in contact with each other. In the open state, the first contact surface 110 and the second contact surface 220 are far away from each other, and the user can put the hair between the first contact surface 110 and the second contact surface 220. At the same time, the cavity 300 is a complete cavity 300. During use, when the curling mechanism switches between a closed state and an open state, the first heat conductive member 100 and the second heat conductive member 200 will not cause problems of hair getting stuck or clamped, which can effectively improve the comfort of the curling mechanism and thus improve the comfort of the curling iron. The cavity 300 has a peak portion 310 of an arc structure and a trough portion 320 disposed on both sides of the peak portion 310, wherein the arc structure of the peak portion 310 is larger than the arc structure of the trough portion 320; specifically, the peak portion 310 is disposed between the two trough portions 320, and the arc structure in the middle portion is larger than the arc structures on both sides, that is, the arc structure of the peak portion 310 in the middle portion is larger than the arc structures of the trough portions 320 on both sides, and the wave shape formed by the hair placed in the cavity 300 at this time can make the arc in the middle larger and the arcs on both sides relatively smaller, so that the hair made by the curling iron of the same size can form a larger wave shape, thereby meeting the needs of some users and solving the technical problems existing in the prior art. However, the present design is not limited to this, and if the two peak portions are disposed on both sides of a trough portion, the arc structure of the trough portion in the middle portion is larger than the arc structure of the peak portions on both sides.

[0040] Further, in this embodiment, the height difference between the crest portion 310 and the trough portion 320 is 20 mm-32 mm (see Figure 4Further, in this embodiment, the size of the arc structure of the crest portion 310 is 17mm-27mm. However, the present design is not limited thereto. When the cavity 300 forms an approximately M-shaped structure (the M-shaped structure is not shown in the figure), that is, two crest portions are provided on both sides of a trough portion, and the size of the arc structure of the trough portion is 17mm-27mm (see Figure 4 In this way, under the condition of a larger drop and a larger arc size, the curling mechanism can form a large wave shape, and with the design of the first gap 330 being large in the middle, more hair can be put in at a time while forming a large wave shape, thereby improving the styling efficiency. At the same time, in this embodiment, if the drop is less than 20mm or greater than 32mm, the drop of the large wave shape is too small or too large, resulting in a decrease in the beauty of the large wave shape. If the size of the arc structure in the middle is less than 17mm, that is, in this embodiment, the size of the arc structure of the crest part 310 is less than 17mm, the curling mechanism will not be able to form a large wave shape. If the size is greater than 27mm, the large wave shape formed by the curling mechanism will be too large, resulting in a decrease in beauty. At the same time, if the size of the crest part 310 is 17mm-27mm and the drop is 20mm-32mm, the curling iron of the same size can make a larger and larger wave hair shape.

[0041] Furthermore, in one embodiment, the central angle of the arc structure of the trough portion 320 is less than one hundred and eighty degrees, and the central angle of the arc structure of the crest portion 310 is less than or equal to one hundred and eighty degrees. Specifically, the central angle of the arc structure of the crest portion 310 is close to one hundred and eighty degrees, and the central angle of the arc structure of the trough portion 320 is less than one hundred and eighty degrees. In this case, the hair curled by the curling mechanism can have a larger curl near the crest portion, and a relatively smaller curl near the trough portion, so that the wavy hair is more beautiful, further solving the technical problems existing in the prior art.

[0042] Furthermore, in one embodiment, the difference between the diameter of the arc structure of the trough portion and the diameter of the arc structure of the crest portion is 3mm-6mm. Specifically, this is to make the curl of the created shape more beautiful and make the created wavy hair shape more natural.

[0043] Further, when the height difference between the crest portion 310 and the trough portion 320 is 20mm-32mm, the size of the arc structure of the crest portion 310 is 17mm-27mm, the central angle of the arc structure of the trough portion is less than one hundred and eighty degrees, the central angle of the arc structure of the crest portion is less than or equal to one hundred and eighty degrees, and the difference between the diameter of the arc structure of the trough portion and the diameter of the arc structure of the crest portion is 3mm-6mm, within this range, the curling mechanism structure can be made smaller, and at the same time, a larger wave shape can be made, thereby improving the styling efficiency.

[0044] In one embodiment, reference Figure 3 , Figure 4 The two troughs 320 are symmetrically arranged about the crest 310, so that the size of the curling mechanism can be small, which is convenient to carry and can also form a large wave-shaped curling effect, simplifying the styling technique. In this embodiment, there is a structure with one crest 310 and two troughs 320, so that the cavity 300 forms an approximately W-shaped structure. However, the present design is not limited to this. In other embodiments, the cavity 300 has two troughs 320 and one crest 310. In this case, the cavity 300 forms an approximately M-shaped structure.

[0045] In one embodiment, the cavity 300 further comprises a first gap portion 330, the first gap portion 330 being arranged between the crest portion 310 and the trough portion 320, and the first gap portion 330 being arranged to be gradually narrowed toward the crest portion 310 and the trough portion 320. Specifically, the first gap portion 330 arranged between the crest portion 310 and the trough portion 320 is gradually widened at both ends toward the middle portion, that is, the first gap portion 330 gradually narrows at the ends close to the crest portion 310 and the trough portion 320, and at this time, the first gap portion 330 is a structure with a large middle portion and small ends. In this way, the first gap portion 330 is gradually narrowed near the crest and the trough, and the gradually narrowing shooting can help fix the hair and reduce The possibility of hair slipping off the first heat-conducting member 100 and the second heat-conducting member 200 helps to stabilize the hair on the curling iron, and the tapered design can reduce the situation where the hair is over-squeezed near the crests and troughs, thereby reducing the risk of hair damage, and the tapered design can also help form a more natural curling effect; at the same time, since the two ends are narrower and the middle part is wider, the hair can be distributed more evenly on the curling structure, ensuring that the hair can be evenly heated, thereby achieving a better curling effect, and since the cavity 300 is a complete cavity 300 and the middle part is wider, when accommodating more hair, there is no need to worry about the hair falling out of the cavity 300.

[0046] Meanwhile, in this embodiment, reference Figure 3 , Figure 4The two ends of the first gap portion 330 are tapered, which can optimize the matching problem caused by tolerance in the actual production process. That is, when the curling mechanism is closed, the wave-shaped cavity 300 formed is a continuous cavity 300 body, and the distance between the first contact surface 110 and the second contact surface 220 at the crest portion 310 and the trough portion 320 is small, thereby ensuring the matching of the first heat conductive member 100 and the second heat conductive member 200, and enabling the curling mechanism to be closed together.

[0047] Furthermore, in this embodiment, the maximum gap of the first gap portion 330 is 0.5 mm-2 mm (see Figure 4 In the embodiment, the maximum gap of the first gap portion 330 formed when the curling mechanism is closed is 0.5 mm-2 mm. Under this gap, the hair between the crest portion 310 and the trough portion 320 can be better accommodated after the curling mechanism is closed, and the hair between the crest portion 310 and the trough portion 320 can be better contacted with the first contact surface 110 and the second contact surface 220, thereby increasing the heating area of ​​the hair and making the hair heated more evenly. Furthermore, if the gap of the first gap portion 330 is less than 0.5 mm, the curling mechanism will be inconvenient to close. If the gap is greater than 2 mm, the hair between the crest portion 310 and the trough portion 320 will not be able to contact the first contact surface 110 or the second contact surface 220 well after the curling mechanism is closed.

[0048] In one embodiment, reference Figure 3 , Figure 4 The cavity 300 has a second gap portion 340, and the second gap portion 340 is arranged to be gradually widened from the crest portion 310 or the trough portion 320 toward the outside of the curling mechanism. Further, in this embodiment, when the outermost portion of the cavity 300 close to the curling mechanism is the crest portion 310, the second gap portion 340 is arranged to be gradually widened from the crest portion 310 toward the outside of the curling mechanism. If the outermost portion of the cavity 300 close to the curling mechanism is the trough portion 320, the second gap portion 340 is arranged to be gradually widened from the trough portion 320 toward the outside of the curling mechanism. In this embodiment, the second gap portion 340 is provided, so that the gap at the position of the outer area of ​​the cavity 300 close to the curling mechanism gradually increases, that is, the gap at the edge of the cavity 300 gradually increases. The gradual increase in the gap can reduce the obvious creases on the hair at the edge of the cavity 300 when the curling mechanism forms a curl on the hair. If the hair has obvious creases, the beauty of the heated hair will be reduced.

[0049] Further, in this embodiment, referring to Figure 3 , Figure 4 The maximum gap of the second gap portion 340 is 3 mm (see Figure 4A3 size), specifically, in the present application, if the maximum gap of the second gap portion 340 is too small and less than 1 mm, the hair at the edge of the cavity 300 is prone to slight creases; if the maximum gap of the second gap portion 340 is too close to 0 mm, the hair at the edge of the cavity 300 is prone to obvious creases; if the maximum gap of the second gap portion 340 is greater than 3 mm, the hair at the edge of the cavity 300 is not easy to contact the first contact surface 110 and the second contact surface 220, resulting in uneven heating of the hair and the problem of insufficient heating.

[0050] In one embodiment, reference Figure 2 , Figure 4 The first heat-conducting member 100 and the second heat-conducting member 200 are configured as a wave structure, so that the production and processing of the first heat-conducting member 100 and the second heat-conducting member 200 can be facilitated. At the same time, the first heat-conducting member 100 and the second heat-conducting member 200 are configured as a wave structure, that is, the thickness of the first heat-conducting member 100 is relatively uniform, and the thickness of the second heat-conducting member 200 is also relatively uniform, wherein relatively uniform should be understood as the thickness difference of the heat-conducting member is small within a certain range; rather than being understood as the thickness of the heat-conducting member is exactly the same; the curling mechanism includes The heating element 400 is installed in the crest or trough of the heat conductive element away from the cavity 300. When the heating element 400 is installed in the crest or trough, during the heat transfer process, since the thickness of the heat conductive element is relatively uniform, the heat can be transferred faster and more evenly. In combination with the first gap portion 330, the heat generated by the heating element 400 can be transferred faster and more evenly, and the hair can be heated faster and more evenly, thereby further shortening the styling time and improving the styling efficiency.

[0051] The present invention also provides a hair curler 500, referring to Figure 1 , Figure 2 The curling iron 500 includes a curling mechanism and a heating element. The specific structure of the curling mechanism refers to the above embodiment. Since the curling iron adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. The heating element is installed in the curling mechanism. Specifically, the heating element 400 is installed in the crest or trough of the heat conductive element away from the cavity 300. At this time, when the heating element 400 is installed in the crest or trough, in the process of transferring heat, the heat can be transferred faster and more evenly due to the uniform thickness of the heat conductive element. In addition, in conjunction with the above-mentioned first gap portion 330, the heat generated by the heating element 400 can be transferred faster and more evenly, and the hair can be heated faster and evenly, further shortening the styling time and improving the styling efficiency.

[0052] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention and the drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
