[0029] The handle 10 includes a bottom shell 11 and a cover shell 12 covering the bottom shell 11, the rotating shaft 20 is mounted on one end of the bottom shell 11 and the cover shell 12, the motor 60 and the control panel 70 are fixedly mounted on the inner side of the bottom shell 11, and the power cord 80 is mounted on the other end of the bottom shell 11 and the cover shell 12. The assembled and covered handle 10 structure is not only convenient for the installation and molding of the automatic curling iron 100, but also conducive to the fault repair operation of the automatic curling iron 100.

[0030] The rotating shaft 20 includes a fixed axis plate 21, a moving axis plate 22, a mounting plate 23, a transmission shaft 24 and a fixed pressing plate 25. The fixed axis plate 21 is mounted on one end of the handle 10, and a limit bar 211 is provided at the lower end thereof. The limit bar 211 and the inner side of the handle 10 are mutually limited. The fixed axis plate 21 is also provided with two groups of electric contact rings 212. Both groups of electric contact rings 212 are clamped and mounted on the outer side of the fixed axis plate 21 and are electrically connected to the control panel 70. The moving axis plate 22 is clamped and mounted on the outer side of the fixed axis plate 21 and can be movably rotated. The moving axis plate 22 is also provided with a clamping rubber sheet 221 and a plurality of electric contact pins 222. The clamping rubber sheet 221 is clamped and mounted on the outer side of the moving axis plate 22.

[0033] The hair curler 40 includes a clamping sleeve 41, a hair curling barrel 42 and a magnetic clamp ring 43. The clamping sleeve 41 is sleeved on the periphery of the mounting plate 23, the hair curling barrel 42 is fixedly mounted on the outer end of the clamping sleeve 41 and sleeved on the periphery of the heating tube 30, and the magnetic clamp ring 43 is fixedly mounted on the inner end of the clamping sleeve 41 and is magnetically fixed to the magnet 231 on the mounting plate 23. Specifically, in this embodiment, the hair curlers 40 of the same automatic hair curler 100 can be configured in multiple groups, and the multiple groups of hair curlers 40 have different sizes or designs.

[0034] The magnet 231 on the mounting plate 23 and the magnetic clamp 43 in the curling barrel 40 can easily realize the assembly or disassembly between the curling barrel 40 and the main body of the automatic curling device 100. When the curling requirements are different, only the corresponding curling barrel 40 needs to be replaced without the need to equip a large number of automatic curling devices 100 main bodies, which not only facilitates the use of the automatic curling device 100, but also greatly reduces the cost of the automatic curling device 100.

[0035] The elastic clip 50 includes a mounting rod 51, a pressing handle 52, a clip 53 and a fixing spring 54.

[0037] The motor 60 includes a body 61, a transmission 62 and a connecting pipe 63. The body 61 and the transmission 62 are fixedly installed in the bottom shell 11, and the body 61 is electrically connected to the control panel 70, and the two ends of the transmission 62 are respectively connected to the body 61 and the transmission shaft 24 by power, and the connecting pipe 63 is sleeved at the connection between the transmission 62 and the transmission shaft 24. The body 61 generates a driving force under the power supply of the control panel 70, and then is converted into a driving force with large torque and uniform speed through the transmission 62, and finally drives the rotating shaft 20 and the heating tube 30 to rotate. The connecting pipe 63 sleeved at the connection between the body 61 and the dynamic shaft can connect and fix the two, thereby ensuring the smooth transmission of the driving force.

[0038] The control panel 70 includes a first circuit board 71 and a second circuit board 72 connected to the first circuit board 71 by signals. The first circuit board 71 and the second circuit board 72 are both installed in the bottom shell 11, and the first circuit board 71 is located on one side of the power cord 80, and the second circuit board 72 is located on one side of the rotating shaft 20. The first circuit board 71 is provided with a plurality of first control buttons 711 and indicator lights 712, and the second circuit board 72 is provided with a plurality of second control buttons 721.

[0039] When the handle 10 is grasped, the first circuit board 71 is located away from the grasping position, thereby avoiding accidental high temperature burns caused by accidentally touching the first control button 711 for adjusting the temperature; and the second circuit board 72 is located near the thumb, so that the second control button 721 can be pressed at any time to control the automatic rotation function of the automatic curling iron 100.

[0040] The handle 10 further includes a plurality of first button caps 13 and a second button cap 14. The first button cap 13 is fan-shaped, and the plurality of first button caps 13 are integrally spliced ​​to form a circular design. The plurality of first button caps 13 are all snap-fitted and mounted on the face shell 12 and correspond one by one to the plurality of first control buttons 711. The plurality of second button caps 14 are all snap-fitted and mounted on the face shell 12 and correspond one by one to the plurality of second control buttons 721. The handle 10 further includes a transparent display panel 15, which is snap-fitted and mounted on the face shell 12 and corresponds one by one to the plurality of indicator lights 712.

[0041] The key cap corresponds to the control button, which is not only more convenient for pressing the button, but also the mark on the key cap is convenient for the operator to identify the function of the control button. The transparent display panel 15 ensures the display effect of the indicator light 712 without affecting the internal packaging of the handle 10.

[0042] The power cord 80 includes a rotating buckle 81 and a wire terminal 82. The rotating buckle 81 is engaged with the rear of the bottom shell 11 and can rotate flexibly, and the wire terminal 82 is inserted into the rotating buckle 81 and is electrically connected to the control panel 70. The power cord 80 with a rotating structure can effectively prevent the wire from twisting and tangling and breaking.

[0043] When the utility model is used, firstly, a curling drum 40 of corresponding specifications is selected according to different customer needs and the curling drum 40 is magnetically attached to the automatic curling machine 100. Then, the power cord 80 is powered on. After the power of the power cord 80 is transmitted to the control panel 70, it is distributed to the motor 60 or the heating tube 30. After the machine is powered on, the first control button 711 is pressed to start the heating tube 30 to start heating until the set temperature. Then, the pressing handle 52 of the elastic clip 50 is pressed to open the clip 53, and after the hair end is clamped between the clip 53 and the curling drum 42, the pressing handle 52 is released to reset the clip 53 to fix the hair. Then, the second control button 721 is pressed to start the motor 60. Under the drive of the motor 60, the curling drum 40 can rotate forward or reverse to achieve the curling and shaping of the hair. After the shaping is completed, the elastic clip 50 is opened again to pull the automatic curling machine 100 out of the hair, and the second control button 721 is pressed to quickly reset the angle of the rotating shaft 20.

[0044] In summary, the beneficial effects of the automatic curling iron 100 of the utility model are as follows: by designing a movable and detachable curling iron, the curling barrels 40 of different specifications can be replaced, so that a single curling iron can achieve different curling styles according to different needs, which is not only more convenient to use, but also greatly saves the cost of the curling iron; the control panel 70 of the split structure is designed, and the buttons for temperature adjustment and rotation control are separately designed at the most suitable position of the handle 10, which is more in line with the concept of ergonomics; and the sensor arranged on the control panel 70 can accurately judge and control the angle reset of the rotating shaft 20 to ensure that the position of the elastic clip 50 corresponds to the handle 10 and each control button; and the indicator light 712 on the control panel 70 better indicates the temperature or rotation state, making the use of the curling iron safer and more reliable; the rotatability of the power cord 80 greatly reduces the risk of the power cord 80 breaking due to the twisting and knotting of the wire; the utility model is highly practical and has a strong promotion significance.
