- A rotating curling iron is provided according to the present disclosure.
- In this embodiment of the present disclosure, as shown in
FIG. 1 toFIG. 13 , the rotating curling iron includes ahandle 10, a connectingseat 20, and a rotatingcurling iron rod 40. Thehandle 10 includes ahousing 11, an electric control device and adriving motor 16, wherein the drivingmotor 16 is electrically connected to the electric control device and thehousing 11 has an opening end. The connectingseat 20 is rotatably mounted in thehousing 11 and connected to the drivingmotor 16, wherein the connectingseat 20 has a connecting end exposed from the opening end, and a sealing structure is provided between the connectingseat 20 and an inner wall of the opening end. The rotatingcurling iron rod 40 includes aheating rod 41 and a fixingseat 42 connected to one end of theheating rod 41, wherein the fixingseat 42 is connected with the connecting end. - Specifically, during use, the driving
motor 16 can be controlled to start or stop by the electric control device, and when the drivingmotor 16 is started, the drivingmotor 16 can drive the connectingseat 20 to rotate, thereby driving the curlingiron rod 40 to rotate to curl hair. The fixingseat 42 may be provided with a latch extending to a side of theheating rod 41 so that when curling hair, the end of hair may be placed between the latch and theheating rod 41, thereby reducing the risk of hair falling from the rotatingcurling iron rod 40 during the curling process. Alternatively, the fixingseat 42 is provided with a rotatable clipping plate extending to a side of theheating rod 41 so that when curling hair, the clipping plate can be opened relative to the rotatingcurling iron rod 40, and hair curling can be carried out after the end of hair is placed between the clipping plate and theheating rod 41, also reducing the risk of hair falling from the rotatingcurling iron rod 40 during the curling process. Alternatively, no hair clipping structure may be provided, and during use, the hair is pre-fixed by repeatedly winding the end of hair around theheating rod 41 or the fixingseat 42 first, and hair curling is then carried out. In addition, the drivingmotor 16 may be an inner-rotor motor or an outer-rotor motor. - In addition, the fixing
seat 42 can be detachably connected to the connecting end in a variety of ways. For example, in an embodiment, the fixingseat 42 is secured to the connecting end by snap fit. In other embodiments, the fixingseat 42 is connected to the connecting end by magnetic attraction. In further embodiments, the fixingseat 42 is connected to the connecting end by a threaded structure. - In the technical solution of the present disclosure, a driving
motor 16 and a connectingseat 20 are arranged in thehandle 10, so that the connectingseat 20 is rotatably mounted in thehousing 11 of thehandle 10 and connected with the drivingmotor 16; and the connecting end of the connectingseat 20 is exposed from the opening end of thehousing 11 and connected with the fixingseat 42 of the rotatingcurling iron rod 40. With such arrangement, the drivingmotor 16 can be started to drive thehair curling rod 40 to rotate during use, so as to achieve electric hair curling. That is, the user does not need to manually rotate the rotating curling iron, which makes the hair curling very easy for the user. Moreover, a sealing structure is provided between the connectingseat 20 and the inner wall of the opening end, which can effectively reduce the risk of foreign matter, such as water or dust, flowing into thehandle 10 from the space between the connectingseat 20 and the inner wall of the opening end, and improve the waterproof effect of the rotating curling iron while achieving the electric hair curling. - In some embodiments, the sealing structure includes a sealing
groove 111 formed on the inner wall of the opening end and a sealingprotrusion 27 formed on the outer periphery of the connectingseat 20. The sealingprotrusion 27 is a ring extending in a rotation direction of the connectingseat 20, the sealinggroove 111 is arranged to enclose the outer periphery of the connectingseat 20, and the sealingprotrusion 27 is slidably mounted in the sealing groove 111 (that is, when the connectingseat 20 rotates relatively, the sealingprotrusion 27 can rotate in the sealinggroove 111, following the connectingseat 20, and when the groove wall of the sealinggroove 111 contacts the sealingprotrusion 27, the two can slide relative to each other). That is, the sealingprotrusion 27 is in a clearance fit with the sealinggroove 111. Such arrangement of the sealingprotrusion 27 and the sealinggroove 111 can increase the length of the gap between the connectingseat 20 and thehousing 11, i.e., increase the flow path of water between the connectingseat 20 and thehousing 11, which can effectively reduce the possibility of water flowing into thehousing 11 through the gap between the connectingseat 20 and thehousing 11, and reduce the risk of water entering between the connectingseat 20 and thehousing 11. In other embodiments, the sealing structure includes a sealing ring sleeved outside the connectingseat 20. - In some embodiments, the fixing
seat 42 and the connecting end are detachably connected, so that the rotatingcurling iron rod 40 can be easily replaced. For example, the user may purchase rotatingcurling iron rods 40 of different specifications, and select corresponding rotatingcurling iron rods 40 for hair curling according to different needs during use. In addition, when the rotatingcurling iron rod 40 or handle 10 is damaged, only the damaged part therein needs to be replaced without replacing the whole rotating curling iron. - In some embodiments, the rotating
curling iron rod 40 further includes a first wiring assembly, and thehandle 10 further includes a second wiring assembly electrically connected to the electronic control device. One of the connecting end and the fixingseat 42 is provided with an insertingcavity 201, and the other is provided with an insertingportion 421 mating with the insertingcavity 201. The insertingportion 421 is provided with a first insertinghole 422, the insertingcavity 201 is internally provided with an insertingprotrusion 21, the first wiring assembly is arranged in the first insertinghole 422, and the second wiring assembly is arranged at the insertingprotrusion 21. When the insertingportion 421 is inserted into the insertingcavity 201, the insertingprotrusion 21 is inserted into the first insertinghole 422, and the first wiring assembly is correspondingly connected to the second wiring assembly. - In the present embodiment, the rotating curling iron includes a power line. The power line is mounted at an end, away from the rotating
curling iron rod 40, of thehandle 10, and is electrically connected with the electric control device. The first wiring assembly is electrically connected with a heating structure inside theheating rod 41. The electric control device includes acircuit board 12 arranged in thehousing 11. The second wiring assembly is arranged at the connectingseat 20, and is electrically connected with thecircuit board 12. The power line is integrally connected to thehandle 10, or the power line is detachably connected to thehandle 10. - One of the connecting end of the connecting
seat 20 and the fixingseat 42 of the rotatingcurling iron rod 40 is provided with the insertingcavity 201, and the other is provided with the insertingportion 421 mating with the insertingcavity 201. The insertingportion 421 is provided with the first insertinghole 422, and the insertingcavity 201 is internally provided with the insertingprotrusion 21. Further, the first wiring assembly is arranged in the first insertinghole 422, and the second wiring assembly is arranged at the insertingprotrusion 21. Due to the above arrangement, when the insertingportion 421 is inserted into the insertingcavity 201, the insertingprotrusion 21 is inserted into the first insertinghole 422, and the first wiring assembly is correspondingly connected to the second wiring assembly. Due to the above arrangement, with the insertingportion 421 inserted into the insertingcavity 201, the length of the gap between the first wiring assembly and the second wiring assembly, and the outer side surface of the rotating curling iron can be increased, which is equivalent to increasing the path of water entering the first wiring assembly and the second wiring assembly from the outside of the rotating curling iron. Such arrangement can also reduce the risk of water entering the first wiring assembly and the second wiring assembly, that is, reduce the risk of water invasion between the rotatingcurling iron rod 40 and thehandle 10, and improve the waterproof effect of the rotating curling iron during use. Moreover, the inserting engagement between the fixingseat 42 and the connectingseat 20 enlarges the contact area between the fixingseat 42 and the connectingseat 20, and improves the stability of connection between the fixingseat 42 and the connectingseat 20. - In some embodiments, the inserting
protrusion 21 is provided with multiple second insertingholes 211, the first wiring assembly includes multipleconductive pillars 51 arranged in the first insertinghole 422, and the second wiring assembly includesconductive components 15 each arranged in the corresponding second insertinghole 211. When the insertingportion 421 is inserted into the insertingcavity 201, the insertingprotrusion 21 is inserted into the first insertinghole 422, and eachconductive pillar 51 is correspondingly inserted into the respective inserting hole and contacts the correspondingconductive component 15. With such arrangement, the multipleconductive components 15 can be separated from each other, and the path between theconductive components 15 is increased. That is, when the rotatingcurling iron rod 40 is removed, even if a small amount of water drips into the insertingcavity 201, it is still difficult for the water to contact twoconductive components 15 at the same time, i.e., a short circuit is difficult to occur between two adjacentconductive components 15, which greatly reduces the risk of short circuit of the second wiring assembly caused by water invasion. In other embodiments, the second wiring assembly includes multiple conductive contact plates provided on an end face of the insertingprotrusion 21, wherein the multiple conductive contact plates are in one-to-one correspondence with the multipleconductive pillars 51. - In some embodiments, each
conductive component 15 is cylindrical, and when the insertingportion 421 is inserted into the insertingcavity 201, the respectiveconductive pillar 51 is inserted into an inner hole of the correspondingconductive component 15. Such arrangement can reduce the requirement of mating accuracy of theconductive pillars 51 and theconductive components 15, bring theconductive components 15 into better contact with theconductive pillars 51, and reduce the risk of poor contact between theconductive components 15 and theconductive pillars 51. In other embodiments, eachconductive component 15 may also be of an elastic-sheet structure provided in the corresponding second insertinghole 211. - In some embodiments, a side wall of each
conductive component 15 is provided with anotch 151 which extends axially throughout two ends of theconductive component 15, and an inner side of theconductive component 15 is provided with a protrudingportion 152 which abuts against an outer peripheral surface of the correspondingconductive pillar 51 when theconductive pillar 51 is inserted into the conductive component. Specifically, after theconductive pillar 51 is inserted into the inner hole of theconductive component 15 and theconductive pillar 51 abuts the protrudingportion 152, theconductive component 15 is expanded outward, and elastically deforms to squeeze theconductive pillar 51 at the same time, so that theconductive component 15 abuts tightly against the outer peripheral surface of theconductive pillar 51, and theconductive component 15 is in close contact with theconductive pillar 51, further reducing the risk of poor contact between theconductive component 15 and theconductive pillar 51. - In some embodiments, a cavity wall of the inserting
cavity 201 has afirst arc surface 24 and afirst plane 25. Thefirst arc surface 24 and thefirst plane 25 are distributed along the rotation direction of the connectingseat 20. The outer peripheral side of the insertingportion 421 is provided with asecond arc surface 423 and asecond plane 424. When the insertingportion 421 is inserted into the insertingcavity 201, thefirst plane 25 is opposite to thesecond plane 424, and thefirst arc surface 24 is opposite to thesecond arc surface 423. Specifically, the cavity wall of the insertingcavity 201 has two opposite first arc surfaces 24 and two oppositefirst planes 25. The two first arc surfaces 24 and the twofirst planes 25 are alternately distributed along the rotation direction of the connectingseat 20. Likewise, the outer peripheral side of the insertingportion 421 has two opposite second arc surfaces 423 and two oppositesecond planes 424. The two second arc surfaces 423 and the twosecond planes 424 are alternately distributed along the rotation direction of the connectingseat 20. When the insertingportion 421 is inserted into the insertingcavity 201, the twofirst planes 25 are in one-to-one correspondence with the twosecond planes 424, and the two first arc surfaces 24 are in one-to-one correspondence with the two second arc surfaces 423. Such arrangement can prevent the fixingseat 42 from rotating relative to the connectingseat 20, and improve the stability of installation of the rotatingcurling iron rod 40. In other embodiments, the cavity wall of the insertingcavity 201 may have only onefirst arc surface 24 and onefirst plane 25. - In some embodiments, one of the outer side surface of the inserting
portion 421 and the cavity wall of the insertingcavity 201 is provided with a mistake-proof raisedrib 23, and the other is provided with a mistake-proof groove 428. When the insertingportion 421 is inserted into the insertingcavity 201, the mistake-proof raisedrib 23 is inserted into the mistake-proof groove 428. Such arrangement makes it convenient for the user to install the rotatingcurling iron rod 40 and avoids wrong installation by the user. - In some embodiments, the connecting end extends out from the opening end of the
housing 11, and the rotatingcurling iron rod 40 further includes a snapping structure. The snapping structure includes asnapping component 31 and apressing component 32, the snappingcomponent 31 is movably mounted at the connecting end, and a snappingend 311 of the snappingcomponent 31 is located in the insertingcavity 201. Thepressing component 32 is movably mounted at the connecting end, and abuts against a side, facing away from the insertingcavity 201, of the snappingcomponent 31. The fixingseat 42 is provided with the insertingportion 421, a claspingportion 425 is provided on the outer peripheral side of the insertingportion 421, and the insertingportion 421 is provided with the second wiring assembly. When the insertingportion 421 is inserted into the insertingcavity 201, the claspingportion 425 is located in the insertingcavity 201, and the snappingend 311 of the snappingcomponent 31 is in a snap fit with the claspingportion 425. - Specifically, the snapping
end 311 is formed with a hook extending in a direction away from the insertingcavity 201, an end face, away from theheating rod 41, of the claspingportion 425 is provided with a snappinghole 426, and the hole wall, away from the insertingportion 421, of the snappinghole 426 is provided with a bucklingportion 427. When the insertingportion 421 is inserted into the insertingcavity 201, the snappingend 311 of the snappingcomponent 31 is inserted into the snappinghole 426, and the hook is held on the bucklingportion 427, thus achieving the snap fit of the connectingseat 20 with the fixingseat 42. When the rotatingcurling iron rod 40 needs to be removed, thepressing component 32 is pressed downward so that the snappingcomponent 31 moves towards the insertingcavity 201, and when the hook is detached from the bucklingportion 427, the insertingportion 421 can be pulled out from the insertingcavity 201 to remove the rotatingcurling iron rod 40. In other embodiments, the snappingcomponent 31 has the snappingend 311, a pressing end, and a hinge portion between the snappingend 311 and the pressing end. The hinge portion is hinged to the connectingseat 20. The snappingend 311 has the hook extending towards the insertingcavity 201. Thepressing component 32 abuts against a side, facing away from the insertingcavity 201, of the pressing end. - The snapping
end 311 of the snappingcomponent 31 is located in the insertingcavity 201. When the insertingportion 421 is inserted into the insertingcavity 201, the claspingportion 425 is located in the insertingcavity 201, and is in a snap fit with the snappingend 311 of the snappingcomponent 31. Thus, even when the rotatingcurling iron rod 40 is removed from the connectingseat 20, the snappingend 311 of the snappingcomponent 31 can be located in the insertingcavity 201, so as to avoid the risk of the snappingend 311 extending out of the insertingcavity 201 and being damaged by collision, thereby improving the use reliability of the snapping structure. - In some embodiments, the snapping structure further includes an
annular housing 33, theannular housing 33 is sleeved outside the connecting end, theannular housing 33 and the connecting end together define a mountingcavity 331, theannular housing 33 is provided with andowel hole 332 communicating with the mountingcavity 331, and the snappingcomponent 31 is movably mounted in the mountingcavity 331 and has a locked position and an unlocked position. Thepressing component 32 abuts against a side, facing away from the connectingseat 20, of the snappingcomponent 31 and is exposed through thedowel hole 332. The connectingseat 20 is provided with a viahole 203 communicating the insertingcavity 201 with the mountingcavity 331, and the snappingend 311 of the snappingcomponent 31 extends into the insertingcavity 201 through the viahole 203. - Specifically, the hook of the snapping
end 311 extends towards theannular housing 33, and is separated from the inner side surface of theannular housing 33. When the insertingportion 421 is inserted into the insertingcavity 201, the snappingend 311 of the snappingcomponent 31 is inserted into the snappinghole 426, and the hook is held on the bucklingportion 427, thus achieving the snap fit of the connectingseat 20 with the fixingseat 42. When the rotatingcurling iron rod 40 needs to be removed, thepressing component 32 is pressed downward so that the snappingcomponent 31 moves towards the insertingcavity 201, and when the hook is detached from the bucklingportion 427, the insertingportion 421 can be pulled out from the insertingcavity 201 to remove the rotatingcurling iron rod 40. In this arrangement, theannular housing 33 is arranged outside the connectingseat 20, so that the mountingcavity 331 is formed between theannular housing 33 and the outer side of the connectingseat 20 to mount thesnapping component 31 and thepressing component 32. This arrangement simplifies the structure of the connectingseat 20. Alternatively, the connectingseat 20 may be provided as an integral structure to improve the structural strength of the connectingseat 20, thereby reducing the risk of deformation or damage of the connectingseat 20 during rotation, and further improving the reliability of automatic hair curling of the rotating curling iron. Moreover, the snappingend 311 of the snappingcomponent 31 is arranged in the insertingcavity 201, thereby avoiding the risk of the snappingend 311 extending out of the insertingcavity 201 and being damaged by collision, and further improving the use reliability of the snapping structure. - In other embodiments, the connecting
seat 20 is pieced together from two seat bodies, that is, two seat bodies jointly unite to form the insertingcavity 201, the mountingcavity 331 and the viahole 203, and the uniting surfaces of the two seat bodies are parallel to the rotation axis of the connectingseat 20. - In some embodiments, the inner side of the
annular housing 33 is provided with a position-limitinggroove 333 at a position corresponding to the viahole 203, the position-limitinggroove 333 penetrates through an end face of theannular housing 33 and the cavity wall of the mountingcavity 331, the claspingportion 425 protrudes from the outer peripheral surface of the insertingportion 421, and an end face, facing away from theheating rod 41, of the claspingportion 425 is provided with the snappinghole 426. When the insertingportion 421 is inserted into the insertingcavity 201, the claspingportion 425 is correspondingly inserted into the position-limitinggroove 333, and the snappingend 311 of the snappingcomponent 31 is snapped into the snappinghole 426. Such arrangement takes advantage of the engagement between the space of theannular housing 33 and the snapping portion, and prevents the snapping portion and the snapping structure from occupying the engagement space of the insertingportion 421 and the insertingcavity 201, so that the fixingseat 42 and the connectingseat 20 have a large engagement area and are connected stably, and the structure of the connectingseat 20 and the snapping structure can be compact, which is beneficial to reducing the size of the rotatingcurling iron rod 40 and makes it easy for the user to hold and use. In addition, when the claspingportion 425 is correspondingly inserted into the position-limitinggroove 333, rotation of the fixingseat 42 relative to the connectingseat 20 can be effectively prevented, so that the installation of the rotatingcurling iron rod 40 is more stable. - In some embodiments, the snapping structure further includes an
elastic component 35 which is compressed between the snappingcomponent 31 and thepressing component 32. Specifically, when thepressing component 32 is pressed downward, the snappingcomponent 31 compresses theelastic component 35 so that the elastic component deforms under compression, while when thepressing component 32 is released, the snappingcomponent 31 is driven to move away from the insertingcavity 201 under the elastic action of theelastic component 35. That is, when the insertingportion 421 is inserted into the insertingcavity 201 and the snappingend 311 of the snappingcomponent 31 is inserted into the snappinghole 426, the hook is held on the bucklingportion 427 under the action of theelastic component 35. When the rotatingcurling iron rod 40 needs to be removed, thepressing component 32 is pressed downward so that the snappingcomponent 31 moves towards the insertingcavity 201, and when the hook is detached from the bucklingportion 427, the insertingportion 421 can be pulled out from the insertingcavity 201 to remove the rotatingcurling iron rod 40. Providing theelastic component 35 between the snappingcomponent 31 and thepressing component 32 can simplify the structure of the snappingcomponent 31 and simplify the snapping structure. In other embodiments, the snappingcomponent 31 itself is configured as an elastic-sheet structure to achieve the reset of the snappingcomponent 31. - In some embodiments, the snapping
component 31 is provided with a position-limitinggroove 315, and one end of theelastic component 35 abuts in the position-limitinggroove 315. In this way, the offset of theelastic component 35 relative to thesnapping component 31 can be limited by the position-limitinggroove 315, thereby making the installation of theelastic component 35 stable and improving the reliability of the snapping structure. - In some embodiments, the connecting
seat 20 is provided with a position-limitingprojection 22, theelastic component 35 is a compression spring, and an end, away from thepressing component 32, of theelastic component 35 is sleeved on the position-limitingprojection 22. In this way, the offset of theelastic component 35 relative to the connectingseat 20 can be limited by the position-limitingprojection 22, thereby making the installation of theelastic component 35 stable and improving the reliability of the snapping structure. In addition, using a compression spring as theelastic component 35 can improve the structural strength and reliability of theelastic component 35. In other embodiments, theelastic component 35 may be an elastic sheet or a rubber block. - In some embodiments, the snapping
component 31 further has arotating end 312 opposing the snappingend 311. Therotating end 312 is rotatably mounted in the mountingcavity 331, and thepressing component 32 is sandwiched between therotating end 312 and the snappingend 311. That is, the snappingend 311 is rotatably mounted in the mountingcavity 331 with therotating end 312 as the axis. Compared with the way that the whole of the snappingcomponent 31 is slidably mounted in the mountingcavity 331 along the hole depth direction of the dowel hole 332 (a direction perpendicular to the rotation axis of the connecting seat 20), therotating end 312 in this scheme is basically stationary along the hole depth direction of thedowel hole 332, and the movement space required by therotating end 312 in the mountingcavity 331 is small, so that the space occupied by the snappingcomponent 31 in the mountingcavity 331 can be reduced, and the structural compactness of the connectingseat 20 and the snapping structure can be improved, which is beneficial to reducing the size of the rotatingcurling iron rod 40 and makes it easy for the user to hold and use. - In some embodiments, the mounting
cavity 331 is internally provided with arotating shaft 71, therotating end 312 is provided with arotating groove 314, two ends of therotating groove 314 are through along the axial direction of therotating shaft 71, therotating end 312 is rotatably mounted to therotating shaft 71 via therotating groove 314, and the groove opening of therotating groove 314 is located at a side, facing away from the connectingseat 20, of therotating end 312. Specifically, the outer peripheral surface of the rotating portion is substantially circumferential, and therotating end 312 is substantially in the form of a hook. During installation, the rotatingshaft 71 may be mounted in the mountingcavity 331 first, and therotating end 312 may then be snapped between therotating shaft 71 and the connectingseat 20 through the groove opening of therotating groove 314, so as to avoid the inconvenient locating of the shaft hole of the rotating portion with the rotatingshaft 71 and facilitate the installation of the snappingcomponent 31. - In some embodiments, the connecting
seat 20 is provided with anarc groove 202 at a position corresponding to therotating shaft 71, and therotating end 312 is rotatably mounted in thearc groove 202. Such arrangement allows therotating end 312 to rotate stably in thearc groove 202, and allows the snappingcomponent 31 to rotate stably and reliably, thereby reducing the risk of failure of the snappingcomponent 31. - In some embodiments, the
pressing component 32 is provided with a position-limitingsnapping lug 321, the snappingcomponent 31 is provided with a position-limitingsnapping hole 313, and the position-limitingsnapping lug 321 is movably snapped in the position-limitingsnapping hole 313. Specifically, the length of the position-limitingsnapping lug 321 is greater than the hole depth of the position-limitingsnapping hole 313, so that thepressing component 32 and the snappingcomponent 31 can be well constrained together, and the circumstance that the rotation of the snappingcomponent 31 is limited due to rigid connection between thepressing component 32 and the snappingcomponent 31 can be avoided. - In some embodiments, the snapping structure includes two said snapping
components 31 and two saidpressing components 32, the two said snappingcomponents 31 are respectively arranged on two opposite sides of the connectingseat 20, the two said snappingcomponents 31 are arranged in one-to-one correspondence with the two saidpressing components 32, and theannular housing 33 is provided with the dowel holes 332 corresponding to thepressing components 32. Specifically, the fixingseat 42 is provided with claspingportions 425 corresponding to the snappingcomponents 31, and each snappingcomponent 31 is correspondingly in a snap fit with oneclasping portion 425 when the insertingportion 421 is inserted into the insertingcavity 201. Such arrangement, on the one hand, increases the connection positions of the fixingseat 42 and the connectingseat 20, and improves the stability of connection of the fixingseat 42 with the connectingseat 20, and on the other hand, makes it easy for the user to unlock by pressing the twopressing components 32 at the same time. In addition, in the case that two snappingcomponents 31 and twopressing components 32 are provided, the twopressing components 32 need to be pressed at the same time, so that the two snappingcomponents 31 are detached from the claspingportions 425 at the same time, and then the fixingseat 42 of the rotatingcurling iron rod 40 can be detached from connectingseat 20, thereby reducing the risk of falling of the rotatingcurling iron rod 40 caused by mis-pressing thepressing components 32. - In some embodiments, the
handle 10 further includes the drivingmotor 16 arranged in thehousing 11, and the electric control device is electrically connected with the drivingmotor 16. The connectingseat 20 is rotatably mounted in thehousing 11 and is connected to the output shaft of the drivingmotor 16. Thus, when curling hair, the drivingmotor 16 can drive the connectingseat 20 and the rotatingcurling iron rod 40 to rotate together for hair curling, which greatly facilitates the hair curling of the user. - In some embodiments, the electronic control device further includes a forward-
rotation button 17 and a reverse-rotation button 18 arranged at thehousing 11. The forward-rotation button 17 and the reverse-rotation button 18 are both electrically connected to thecircuit board 12, and are both arranged at one end, close to the rotatingcurling iron rod 40, of thehousing 11 so that the two buttons are convenient for the user to press. - In some embodiments, the electronic control device further includes a
power button 19 arranged at thehousing 11. Thepower button 19 is electrically connected to thecircuit board 12, and is arranged at one end, away from the rotatingcurling iron rod 40, of thehousing 11 so as to avoid the risk of the user touching thepower button 19 by mistake during hair curling. - In some embodiments, the rotating curling iron includes multiple rotating
curling iron rods 40, and one of the multiple rotatingcurling iron rods 40 is selectively mounted to the connectingseat 20. Specifically, the multiple rotatingcurling iron rods 40 each include theheating rod 41 and the fixingseat 42, and theheating rods 41 of the multiple rotatingcurling iron rods 40 differ in size and/or shape, i.e. theheating rods 41 of the multiple rotatingcurling iron rods 40 have different sizes and/or shapes. Thus, it is convenient for the user to select a suitable rotatingcurling iron rod 40 for hair curling according to the hair curling needs, so as to meet individual needs. - In some embodiments, the connecting
seat 20 has a connectingshaft 26 extending toward the drivingmotor 16. An insulating mountingstructure 60 is sleeved outside the connectingshaft 26. The insulating mountingstructure 60 is connected to the output shaft of the drivingmotor 16. Multiple mountingring grooves 613 are provided on a peripheral side of the insulating mountingstructure 60. The multiple mountingring grooves 613 are spaced apart along the axial direction of the connectingshaft 26. The fixingseat 42 is provided with the first wiring assembly. The electric control device includes thecircuit board 12, the second wiring assembly, multipleconductive rings 13 and multipleconductive sheets 14. Thecircuit board 12 is fixed in thehousing 11. Eachconductive ring 13 is correspondingly mounted in one mountingring groove 613 and electrically connected to the second wiring assembly. The multipleconductive sheets 14 are all mounted to thecircuit board 12, and eachconductive sheet 14 correspondingly abuts against an outer side surface of oneconductive ring 13. - Specifically, the insulating mounting
structure 60 and the connectingshaft 26 are fixed relative to each other in the rotation direction of the connectingseat 20, i.e., the insulating mountingstructure 60 and the connectingseat 20 rotate together under the drive of the drivingmotor 16. Thecircuit board 12 is fixed relative to thehousing 11. When the drivingmotor 16 drives the insulating mountingstructure 60 and the connectingseat 20 to rotate, eachconductive ring 13 in the corresponding mountingring groove 613 rotates with the insulating mountingstructure 60, and eachconductive ring 13 rotates relative to the correspondingconductive sheet 14. During the rotation of the respectiveconductive ring 13 relative to the correspondingconductive sheet 14, theconductive sheet 14 abuts against the outer peripheral surface of theconductive ring 13. In this way, a well electrical connection can be achieved between theconductive sheet 14 and theconductive ring 13 while the connectingseat 20 is rotated. - In some embodiments, each
conductive sheet 14 includes a connecting pin 141 and twoelastic contact sheets 142 arranged on two opposite sides of the connecting pin 141. The twoelastic contact sheets 142 are respectively arranged on two opposite sides of the correspondingconductive ring 13 and elastically abut against the outer peripheral surface of the correspondingconductive ring 13, i.e., the twoelastic contact sheets 142 are elastically deformed toward each other. In this way, theconductive sheet 14 can be brought into full contact with theconductive ring 13. Further, even if oneelastic contact sheet 142 is temporarily separated from theconductive ring 13 during the rotation of the connectingseat 20, the risk of poor contact between theconductive sheet 14 and theconductive ring 13 can still be reduced by means of the contact between the otherelastic contact sheet 142 and theconductive ring 13. - In some embodiments, the insulating mounting
structure 60 includes multiple mounting rings 61. Each mountingring 61 includes afirst section 611 and asecond section 612 which are connected with each other. The outer diameter of thefirst section 611 is smaller than the outer diameter of thesecond section 612 to form the mountingring groove 613 on the outer side of thefirst section 611. The multiple mounting rings 61 are sequentially distributed in the direction from the drivingmotor 16 to the connectingseat 20, and thefirst section 611 of each mountingring 61 is located on one side, away from the drivingmotor 16, of itssecond section 612. Theconductive ring 13 is in the form of a continuous ring (closed ring). In this way, even if there is a breach on theconductive ring 13, theconductive sheet 14 is always in full contact with theconductive ring 13 when theconductive ring 13 is rotated for one cycle, and the risk of poor contact between theconductive sheet 14 and theconductive ring 13 can be reduced. - The above embodiments are only preferred embodiments of the present disclosure, and not intended to limit the scope of the present disclosure. Within the inventive concept of the present disclosure, any equivalent structural substitutions made by using the contents of description and drawings of the present disclosure, or direct/indirect applications in other related technical fields are included in the scope of protection of the present disclosure.
