The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and cannot be understood as limitations on the present application.

[0040] like Figure 1-Figure 3 As shown, a curling iron according to an embodiment of the present application comprises a gripping portion 1 for a user to hold, and a curling tube 5 and curling teeth 4 for curling hair arranged on one side of the gripping portion 1 in the length direction. The curling teeth 4 are distributed on the periphery of the curling tube 5 and can rotate around the curling tube 5, so that the hair can be rolled onto the curling tube 5 for curling. The gripping portion 1 comprises an outer shell, which is formed by a first outer shell 11 and a second outer shell 12 fixedly connected, and the first outer shell 11 and the second outer shell 12 enclose an installation space 13 inside the outer shell. A central skeleton 2 is arranged in the installation space 13, and the central skeleton 2 is fixedly connected to the outer shell so as to be stably maintained in the installation space 13.

[0041] Continue to refer Figure 4 In this embodiment, the central skeleton 2 extends along the axial direction of the gripping portion 1, one end of the gripping portion 1 is an open end 14, the curling tube 5 is fixedly connected to the end of the central skeleton 2 close to the open end 14, the curling teeth 4 are rotatably connected to the end of the central skeleton 2 close to the open end 14, and a driving motor 23 is also provided on the central skeleton 2. The driving motor 23 can drive the curling teeth 4 to rotate around the curling tube 5 to achieve automatic curling.

[0042] like Figure 4 , Figure 5 and Figure 7As shown, specifically, in this embodiment, the curling tube 5 extends along the axial direction of the central frame 2, and the curling teeth 4 are sleeved on the outside of the central frame 2. The curling teeth 4 include an annular base 41, on which a plurality of hair-pulling teeth 42 are arranged at intervals; a bearing 3 is sleeved on the outer wall of the central frame 2, and the annular base 41 of the curling teeth 4 is fixed to the outer wall of the bearing 3, thereby realizing a rotation connection with the central frame 2 through the bearing 3. The central frame 2 is preferably formed in one piece, and a plurality of first clamping blocks 311 are arranged at intervals on the outer peripheral wall of the central frame 2, and the top inner wall of the bearing 3 abuts against the first clamping blocks 311; the central frame 2 is also provided with a clamping ring 312, which is sleeved on the outer wall of the central frame 2 and abuts against the bottom inner wall of the bearing 3, thereby cooperating with the first clamping block 311 to realize the installation of the bearing 3 on the central frame 2.

[0043] Continue to refer Figure 5 and Figure 6 A plurality of second clamping blocks 314 are arranged at intervals on the outer peripheral wall of the central frame 2, and the end of the clamping ring 312 away from the bearing 3 abuts against the second clamping block 314, so that the clamping ring 312 and the bearing 3 are firmly held between the first clamping block 311 and the second clamping block 314. The clamping ring 312 is also provided with a first bolt hole 313, and the clamping ring 312 can be fixedly connected to the central frame 2 by bolts to prevent the clamping ring 312 from rotating.

[0044] like Figure 7-Figure 9 As shown, a slot 411 is provided on the inner wall of the annular base 41 of the curling tooth 4. The slot 411 is recessed in the inner wall of the annular base 41. A step surface is formed on the inner wall at the top of the slot 411. The step surface abuts against the top outer wall of the bearing 3. A plurality of second bolt holes are also provided on the end surface of the annular base away from the step surface. Second bolts 412 are threadedly connected in the second bolt holes. The heads of the second bolts 412 abut against the bottom outer wall of the bearing 3. The second bolts 412 cooperate with the step surface to clamp the outer wall of the bearing 3 onto the annular base 41 of the curling tooth 4.

[0045] In this embodiment, the slot 411 extends from the step surface to the end of the annular base 41. During installation, the bearing 3 is pressed into the slot 411 from the end of the annular base 41. Figure 7 As shown, the inner wall of the slot 411 is configured to be an uneven “wave shape”, which can make the connection between the outer wall of the bearing 3 and the curling teeth 4 more stable.

[0046] like Figure 7 , Figure 6 and Fig. 9As shown, a plurality of teeth are also provided on the inner peripheral wall of the annular base 41, and the plurality of teeth form a driven gear 413 on the curling tooth 4. A gear groove 22 is provided on the outer wall of the central frame 2 at a position corresponding to the teeth, and a driving gear 221 is provided in the gear groove 22. The driving gear 221 is fixedly connected to the rotating shaft of the driving motor 23. Part of the driving gear 221 protrudes from the outer wall of the central frame 2 through the gear groove 22, so that it can mesh with the teeth, that is, part of the teeth on the driving gear 221 can protrude from the outer wall of the central frame 2 through the gear groove 22, so as to mesh with the teeth on the annular base 41; when the driving motor 23 is started, the driving gear 221 can drive the driven gear 413 to rotate, thereby driving the curling tooth 4 to rotate around the central frame 2. Since the driven gear 413 is located on the inner wall of the annular base 41, the curling tooth 4 can be integrally formed, which simplifies the structure and facilitates production. The central frame 2 is integrally formed, and is also provided with a slot for installing the drive motor 23. In this embodiment, the bearing 3 is located between the gear slot 22 and the slot of the drive motor 23, and the central frame 2 is also provided with a channel (not shown in the figure) connecting the gear slot 22 and the slot of the drive motor 23, and the rotating shaft of the drive motor 23 passes through the channel and enters the gear slot 22.

[0047] like Figure 8 , Fig.10 and Fig.11 As shown, the hair curling tube 5 includes a heat-conducting frame 51 and a heating element 512 disposed in the heat-conducting frame 51. The heat-conducting frame 51 extends along the axial direction of the central frame 2, and the bottom of the heat-conducting frame 51 abuts against the end face 21 of the central frame 2 near the opening end 14. A plurality of third bolt holes 211 are disposed on the bottom of the heat-conducting frame 51 and the end face 21 of the central frame 2, and the heat-conducting frame 51 can be fixed to the end face 21 of the central frame 2 by bolts. The heat-conducting frame 51 is made of heat-conducting material. When in use, the hair is wrapped around the outer wall of the heat-conducting frame 51 for curling. In this embodiment, the heat-conducting frame 51 is provided with a mounting hole 511 for mounting the heating element 512, and the heating element 512 can be a thermistor. The mounting hole 511 extends to the bottom of the heat-conducting frame 51, and the end face 21 of the central frame 2 is provided with a wiring hole 212 connected to the mounting hole 511, and the wire on the heating element 512 enters the wiring hole 212 from the mounting hole 511. The central frame 2 is also provided with a wiring channel (not shown in the figure) and a PCB board 24. Figure 8 As shown by the middle arrow, the wire passes through the wiring hole 212 and is connected to the PCB board 24 along the wiring channel, so that the wiring is more orderly and the internal circuit of the curling iron is more neat and organized.

[0048] like Figure 8As shown, the PCB board 24 can be fixed to the central frame 2 by bolt connection. The PCB board 24 is arranged along the axial direction of the central frame 2, and the PCB board 24, the wiring channel and the wiring hole 212 are all located on the same side of the central frame 2 and are basically arranged along a straight line. This can reduce the bending of the wires and make wiring more convenient.

[0049] like Fig.10 , Fig.12 and Fig.13 As shown, in this embodiment, the heat-conducting frame 51 includes two parts connected to each other, namely a first bracket and a second bracket, and the first bracket and the second bracket are both provided with a mounting hole 511 and a heating element 512. An inwardly concave mounting groove 52 is formed on the outer wall of the heat-conducting frame 51 between the first bracket and the second bracket, and an ion emitting device 53 is provided in the mounting groove 52. When the hair is wrapped around the outer wall of the heat-conducting frame 51, the ion emitting device 53 can emit ions to the hair, thereby achieving the effects of curing or anti-static. In this embodiment, the ion emitting device 53 is a plasma emitting device 53, which includes a mounting shell 54 and positive and negative ion emitting needles 561 arranged in the mounting shell 54. The mounting groove 52 is arranged on the outer wall of the heat-conducting frame 51 along the axial direction of the heat-conducting frame 51, and a groove 551 is arranged on the inner wall of the mounting groove 52 along the axial direction of the heat-conducting frame 51, and a convex rib 55 adapted to the groove 551 is arranged on the outer wall of the mounting shell 54 along the axial direction of the heat-conducting frame 51. During installation, the mounting shell 54 is inserted into the mounting groove 52 from one axial end of the heat-conducting frame 51, and the rib 55 is snapped into the groove 551, thereby fixing the mounting shell 54 to the mounting groove 52, that is, assembling the ion emitting device 53 to the heat-conducting frame 51.

[0050] An ion emitting hole 56 is provided through the side wall of the mounting shell 54 close to the outer wall of the heat-conducting frame 51, and the ion emitting needle 561 is connected to the ion emitting hole 56 to emit ions outward from the ion emitting hole 56. Preferably, the side wall of the mounting shell 54 close to the outer wall of the heat-conducting frame 51 is flush with the outer wall of the heat-conducting frame 51 or protrudes from the outer wall of the heat-conducting frame 51 to better emit ions onto the hair. In the present embodiment, the mounting shell 54 includes a first shell 541 and a second shell 542 that are clamped to each other, and the first shell 541 and the second shell 542 are respectively abutted against the inner walls of the mounting groove 52 on both sides of the mounting shell 54, and ribs 55 are provided on the outer walls of the first shell 541 and the second shell 542, and the positive and negative ion emitting needles 561 are arranged between the first shell 541 and the second shell 542. Reference Fig.10 and Fig.11The bottom of the mounting shell 54 abuts against the end face 21 of the central skeleton 2 close to the opening end 14, and a wire arrangement groove 213 is also provided on the end face 21; the bottom of the mounting shell 54 is connected with the wire arrangement hole 212 through the wire arrangement groove 213, and the mounting hole 511 can also be connected with the wire arrangement hole 212 through the wire arrangement groove 213, thereby guiding the wires on the ion emitting device 53 and the heating element 512 into the wire arrangement hole 212 along the wire arrangement groove 213, making the wiring more orderly.

[0051] like Figure 8 As shown, the end of the heat-conducting frame 51 away from the central frame 2 is also fixedly connected to an end cover 57, which blocks the mounting hole 511 and abuts against the top of the ion emitting device 53 to fix the ion emitting device 53 in the mounting groove 52. The end of the end cover 57 away from the heat-conducting frame 51 is also fixed with a heat insulating sheet 58, and the heat insulating sheet 58 is provided with a hair guide hole 581, which can guide the hair into the curling tube 5 and the curling teeth 4 area, and the curling teeth 4 roll the hair onto the curling tube 5.

[0052] The implementation principle of this embodiment is as follows: during installation, first install the driving gear 221, the driving motor 23 and the PCB board 24 to the corresponding positions on the central skeleton 2. Then install the heating element 512 and the ion emission device 53 on the heat-conducting frame 51, and then fix the heat-conducting frame 51 to the end face 21 of the central skeleton 2 by bolts, and pass the wires on the heat-conducting frame 51 through the wiring hole 212, and connect them with the components such as the PCB board 24 on the central skeleton 2 along the wiring channel. Then press the bearing 3 into the slot 411 of the curling tooth 4 to pre-assemble the bearing 3 and the curling tooth 4 into a whole, and then sleeve the whole onto the outer wall of the central skeleton 2, so that the bearing 3 reaches the designated installation position and the bearing 3 is installed and fixed. Finally, the central skeleton 2 is assembled into the gripping part 1 by bolts. The whole installation process is simple and convenient, and the internal structure of the curling iron is more neat and orderly.

[0053] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
