DESCRIPTION OF EMBODIMENTS

[0029] The following will provide a clear and complete description of the technical solution in the embodiments of the present disclosure, in combination with the accompanying drawings.

[0030] Please refer to FIGS. 1-7, an automatic hair curler described in the present disclosure is provided with a pre-fixed position for hair, so that the hair is not loose. A looper 3 can better drive the hair to rotate, improve a curling effect, enhance the heat dissipation performance, accelerate the heat dissipation speed, and avoid burns. In an implementation mode, the automatic hair curler includes a handle 1, on the handle 1, a heating barrel 21 is provided. A top of the heating barrel 21 is provided with a first hair entry position 22 for inserting hair. The looper 3 connected to a driving device is sleeved on an outer periphery of the

[0031] heating barrel 21. The looper 3 is provided with a third hair entry position 33 corresponding to the first hair entry position 22. In an initial state, the third hair entry position 33 corresponds to the first hair entry position 22. In this embodiment, front and top view of the first hair entry position 22 are U-shaped, and a side profile shows an inverted triangular inclination.

[0032] When in use, take one bundle of hair near the root and place it in the first hair entry position 22. The first hair entry position 22 adopts a design with a high rear end and a low front end to increase the effect of placing the hair bundle. After the hair bundle extends from the first hair entry position 22, it will enter the third hair entry position 33. In this embodiment, the looper 3 includes a looper base 31, and the looper base 31 is connected to a driving device (not shown in the figure). The looper base 31 extends vertically upward to form two looper rods 32, and the two looper rods 32 are closely attached to form a U - shaped third hair entry position 33. That is to say, when the hair bundle extends from the first hair entry position 22 and enters the U - shaped third hair entry position 33, when the driving device drives the looper base 31 to rotate, the two looper rods 32 will follow and rotate around the heating barrel 21, and plucking the hair bundle to wrap around the outer circumference of the heating barrel 21. Through the U - shaped plucking, a cooperation between the third hair entry position 33 and the first hair entry position 22 achieves the cutting and winding of the inserted hair bundle. During this process, the hair bundle will be pulled and collided with a side wall of the first hair entry position 22, and the hair bundle is bent laterally. A frictional force generated by the bending of the hair bundle is configured to fix the relative position between the hair bundle and the heating barrel 21, without rolling the hair bundle near the root into it. At the same time, it avoids sliding during use, ensuring the curling effect. By pre-arranging the hair and placing it in the first hair entry position 22, it is possible to avoid irregular entanglement of the hair bundle during the curling process, which may cause harm to the user.

[0033] Besides that, in this embodiment, the heating barrel 21 and the looper 3 form a curling cavity, and a heat dissipation structure is formed at the two looper rods to avoid heat accumulation and achieve rapid heat dissipation.

[0034] The heat dissipation structure of the present disclosure has three implementation modes

[0035] In an implementation mode: there are no components in a space outside the two looper rods 32, thereby forming a first heat dissipation gate 34. The first heat dissipation gate 34 is hollow and unobstructed, and there is no heat accumulation, which can achieve rapid heat dissipation.

[0036] In an implementation mode, both the two looper rods 32 are provided with a plurality of first heat dissipation holes 37. During use, the heat located inside the curling cavity can be dissipated through the first heat dissipation holes 37 to achieve rapid heat dissipation.

[0037] In an implementation mode, namely similar to the above structure, simultaneously forms a first heat dissipation hole 37 and a first heat dissipation gate 34 for the looper 3.

[0038] In the embodiment of the present disclosure, an upper end of the heating barrel 21 transitions into a first arc plate 23 along two sides of the first hair entry position 22, which facilitates the sorting and entry of the hair bundle into the first hair entry position 22.

[0039] In the embodiment of the present disclosure, upper ends of the two looper rods 32 are connected by a looper bridge 35, and the heating barrel 21 passes through the looper bridge 35. The setting of the looper bridge 35 not only helps to limit the relative position of the two looper rods 32 and avoid deformation but also blocks the entrance outside the two looper rods 32 to prevent hair from entering.

[0040] In this embodiment, a position of the looper 3 can be limited by a Hall sensor, so that each start-up can align the U shaped third hair entry position 33 with the first hair entry position 22. There is another situation where a Hall sensor is not set for alignment, which means that before use, the U - shaped third hair entry position 33 may not be aligned with the first hair entry position 22. At this time, a bundle of hair is placed in the first hair entry position 22, and the hair extending from the first hair entry position 22 will be blocked by the looper bridge 35 and will not enter an interior of the looper 3. As the looper 3 rotates, the hair bundle will slide on the surface of the looper bridge 35 to avoid secondary curling and entanglement of the hair. When the U - shaped third hair entry position 33 is aligned with the first hair entry position 22, the hair immediately enters the U - shaped third hair entry position 33, and under the drive of the looper rod 32, the hair bundle will be wrapped around the heating barrel 21.

[0041] In an implementation mode, the looper bridge 35 is connected to a highest point of the U - shaped third hair entry position 33, and a height of the looper bridge 35 at a position opposite to the U - shaped third hair entry position 33 is lower than a height of the U - shaped third hair entry position 33, as shown in FIG. 7, h1 is a height of the highest point of the U - shaped third hair entry position 33, and h2 is a height of the lowest point of the looper bridge 35. The looper bridge 35 of the looper 3 forms a continuous and smooth height change, with height h1>height h2. The height gradually decreases smoothly from h1 to h2, or gradually increases smoothly from h2 to h1.

[0042] In the embodiment of the present disclosure, there are vertically extending convex strips 36 on an inner side of the two looper rods 32, and the convex strips 36 extend into the curling cavity and have the function of guiding and blocking hair, thereby increasing a contact area between the looper 3 and the hair bundle.

[0043] In the embodiment of the present disclosure, a protective shell 4 is connected to the handle 1, and the protective shell 4 is provided on an outer periphery of the looper 3. The protective shell 4 in this embodiment mainly serves as a protective function to prevent people from touching the heating barrel 21 and getting burned. The protective shell 4 includes a second arc plate 41, and the second arc plate 41 is provided with a second heat dissipation gate 42 in the same direction as the first hair entry position 22 on a front side. When the first heat dissipation gate 34 of the looper 3 corresponds to the second arc plate 41, the U - shaped third hair entry position 33 corresponds to the second heat dissipation gate 42. The heat dissipation effect is best when the first heat dissipation gate 34 corresponds to the second heat dissipation gate 42, so that the temperature on the surface of the shell is not too high. An upper end of the second heat dissipation gate 42 is provided with rib plates 43 connected to two sides of the second arc plate 41, and a second hair entry position 44 corresponding to the first hair entry position 22 is formed between the two rib plates 43.

[0044] In this embodiment, the heating barrel 21 is at least partially higher than the looper 3 and the protective shell 4 to improve the heat dissipation effect. Of course, the heating barrel 21 is not much higher to avoid the risk of contact. A height difference between the lowest point of the protective shell 4 and the heating barrel 21 is h3, as shown in FIG. 6, where h3 is less than or equal to 5 cm.

[0045] In this embodiment, the second arc plate 41 is provided with a plurality of heat dissipation holes 245, and the heat dissipation effect can be improved by the cooperation of a plurality of heat dissipation holes 137 and a plurality of heat dissipation holes 245.

[0046] It should be noted that the first heat dissipation gate 34 of the looper 3 is a special case of the first heat dissipation hole 37, that is, the first heat dissipation gate 34 is the first heat dissipation hole 37 with a larger diameter, and both the first heat dissipation gate 34 and the first heat dissipation hole 37 play a role in heat dissipation. The second hair entry position 44 of the protective shell 4 only serves to avoid the yielding function, that is, it does not participate in the function of plucking hair. The second heat dissipation gate 42 of the protective shell 4 is a special case of the second heat dissipation hole 245, the second heat dissipation gate 42 is a second heat dissipation hole 45 with a larger aperture and connected to the second hair entry position 44. Both the second heat dissipation gate 42 and the heat dissipation hole 245 play the same role in heat dissipation. The second heat dissipation gate 42 can be replaced by a plurality of heat dissipation holes 245 with relatively smaller apertures, which is a safer structure and cannot be accidentally inserted by the users fingers and burned.

[0047] In summary, the first heat dissipation gate 34, first heat dissipation hole 37, and third hair entry position 33 of the looper 3 are connected to the second heat dissipation gate 42, second heat dissipation hole 45, and second hair entry position 44 of the protective shell 4. The inner and outer layer are kept holes connected to an outside, which is conducive to the rapid dissipation of heat generated by the heating barrel 21, reducing the external temperature of the protective shell 4, and improving the users comfort experience.
