For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0041] Existing curling irons have limited adjustment range for the clamping force on hair. To address this issue, this application provides a curling iron that can change the torque to easily amplify or reduce the clamping force on the hair several times over, thereby achieving personalized hair styling needs, providing convenience to users, and enhancing the user experience.

[0042] Please see Figures 1 to 5 One embodiment of the curling iron of this application includes: a main body 16 and a clamping structure 6;

[0043] One end of the clamping structure 6 is connected to the main body 16 so that the main body provides force to the clamping structure 6; the main body 16 is rotatably connected to the clamping structure 6 through the rotating connection structure 17, and the rotating connection structure 17 is movable to change the torque and thus change the clamping force of the clamping structure 6 on the hair.

[0044] Specifically, the main body 16 can be cylindrical, but this is not limited here. The clamping structure 6 is rotatably connected to the main body 16 via a rotating connection structure 17. When the user presses the clamping structure 6, it rotates around the rotating connection structure 17 of the main body 16 by a certain angle, thus placing the hair between the clamping structure 6 and the main body 16. When the rotating connection structure 17 moves, since one end of the clamping structure 6 is connected to the main body 16 and the two are not adjusted, the magnitude and direction of the force exerted by the main body 16 on the clamping structure 6 remain unchanged. However, the change in the position of the rotating connection structure 17 causes a change in the lever arm corresponding to the force exerted by the main body 16 on the clamping structure 6, thereby changing the torque. On the other hand, the lever arm corresponding to the force exerted by the clamping structure 6 on a certain point of the hair remains unchanged, and the torques on both sides are the same. Therefore, the force exerted by the clamping structure 6 on that point can be changed according to the degree of torque change.

[0045] In this embodiment, the clamping structure 6 is rotatably connected to the main body 16 via a rotating connection structure 17. One end of the main body 16 is connected to the clamping structure 6, and the rotating connection structure 17 is movable to change the torque, thereby altering the clamping force of the clamping structure 6 on the hair. By moving the rotating connection structure 17, the lever arm is changed to alter the torque, thus easily amplifying or reducing the clamping force of the clamping structure 6 on the hair by several times. This allows for convenient and effective fulfillment of personalized hair styling needs through the movement of the rotating connection structure 17, providing convenience to users and enhancing the user experience.

[0046] Please see Figures 1 to 5 Another embodiment of the hair curler of this application includes: a main body 16 consisting of a curling part 1, a handle part 2 and a connecting part 3; a clamping structure 6 containing clips 4 and clip handles 5; an adjustment structure 7; a connecting rod 10 and an elastic member 11; and a rotating connection structure 17 including a rotating shaft 9.

[0047] The curling part 1 is fixedly connected to the handle part 2 via the connecting part 3; the clip 4 is fixedly connected to the clip handle 5; the clamping structure 6 is rotatably connected to the connecting part 3 via a rotating shaft 9 provided in the connecting part 3 perpendicular to the length direction of the handle part 2; the clip 4 is adapted to the curling part 1 to clamp the hair between the clip 4 and the curling part 1; the connecting part 3 is provided with a guide groove 14, and the rotating shaft 9 is engaged in the guide groove 14;

[0048] Specifically, the main body 16 can be cylindrical, and the curling part 1, the connecting part 3, and the handle part 2 are also cylindrical. These three parts are fixedly connected, either detachably or integrally formed; the specific design is not limited here. The clip 4 and the handle 5 constitute the clamping structure 6. The clip 4 and the handle 5 are fixedly connected at a certain angle, or integrally formed; the specific design is not limited here. The clamping structure 6 is rotatably connected to the connecting part 3 of the curling iron via a pivot 9 that engages within the guide groove 14. When the user presses the handle 5, the clip 4 rotates at a certain angle around the pivot 9 of the connecting part 3, thereby placing the hair between the clip 4 and the curling part 1.

[0049] A first through hole 12 is provided at one end of the connecting part 3 of the main body 16 near the clamping handle 5; one end of the connecting rod 10 passes through the first through hole 12 and is fixedly connected to the clamping handle 5; an elastic element 11 is sleeved on the connecting rod 10, and the elastic element 11 is located between the clamping handle 5 and the first through hole 12; the other end of the connecting rod 10 is located inside the connecting part 3.

[0050] Specifically, one end of the connecting rod 10 extends through the first through hole 12 and out of the connecting part 3, and is fixedly connected to the clamp handle 5, while the other end is located inside the connecting part 3. The elastic member 11 is sleeved on the outside of the connecting rod 10, wherein one end of the elastic member 11 abuts against the clamp handle 5, and the other end abuts against the connecting part 3, and is located between the clamp handle 5 and the first through hole 12.

[0051] The adjustment structure 7 is used to drive the rotating shaft 9 to move within the range of the guide groove 14. It has multiple specific implementations, which are not limited here. Three specific implementations are given below.

[0052] In the first specific embodiment, the adjustment structure 7 includes a pusher 15 and a push rod 13;

[0053] The outer surface of the handle portion 2 of the main body 16 is provided with a first groove, and the pusher 15 is provided in the first groove; a second through hole is provided in the first groove, and the pusher 15 passes through the second through hole and is fixedly connected to the push rod 13; the push rod 13 is movably connected to the rotating shaft 9 so that when the pusher 15 is pushed to move in the first groove, the push rod 13 is driven to move, thereby driving the rotating shaft 9 to move within the range of the guide groove 14.

[0054] Specifically, the pusher 15 is disposed in the first groove on the outer surface of the handle 2, and the width of the pusher 15 is adapted to the width of the first groove. A through hole, i.e., a second through hole, is drilled in the first groove to realize the fixed connection between the pusher 15 and the push rod 13, or an integrally formed structure can be used, which is not limited here. When the user pushes the pusher 15, the push rod 13 moves, thereby driving the rotating shaft 9 to move within the range of the guide groove 14, while the point of application of the force of the connecting rod 10 on the clamp 5 does not change, the elastic element 11 is not compressed or stretched compared with before the pusher 15 is pushed, and the magnitude and direction of the force F of the connecting rod 10 on the clamp 5 do not change. The lever arm L of the force of the connecting rod 10 on the clamp 5 is the perpendicular distance between the line of action of the force and the rotating shaft 9. As the position of the rotating shaft changes, the lever arm L also changes accordingly. Since the torques on the left and right sides of the pivot 9 are the same, i.e., F1*L1=F*L, when the torque changes on the right side and the lever arm L1 of the force exerted by the clip 4 on a certain part of the hair remains unchanged, the magnitude of the force F1 exerted by the clip 4 on that part of the hair changes accordingly.

[0055] In the second specific embodiment, the adjustment structure 7 includes a protrusion;

[0056] The protrusions are located at both ends of the rotating shaft 9 and outside the connecting part 3 of the main body 16, so that when the protrusions are pushed, the rotating shaft 9 can move within the range of the guide groove 14; the protrusions are cylindrical.

[0057] Specifically, protrusions are located at the ends of the rotating shaft 9, one on each side, and the protrusions are located outside the connecting part 3. When the protrusions are pushed, the moving protrusions drive the rotating shaft 9 to move within the range of the guide groove 14, directly changing the lever arm of the force of the connecting rod 10 on the clamp handle 5, thereby further changing the clamping force of the clip 4 on the hair.

[0058] In the third specific embodiment, the push rod 13 structure includes a button, a push rod 13, and a motor;

[0059] A button is provided on the outer surface of the main body 16, and a motor is provided inside the main body 16; the motor is electrically connected to the button, one end of the push rod 13 is movably connected to the rotating shaft 9, and the other end of the push rod 13 is connected to the motor, so that when the button is pressed, the motor is controlled to work and drive the push rod 13 to move, thereby driving the rotating shaft 9 to move within the range of the guide groove 14; the motor is a stepper motor.

[0060] Specifically, a button is provided on the outer surface of the handle 2, and a motor is located inside the handle, with the motor and button electrically connected. The motor is connected to one end of the push rod 13, and the other end of the push rod 13 is movably connected to the rotating shaft. When the button is pressed, the motor works, thereby driving the push rod 13 to move, which in turn drives the rotating shaft 9 to move within the range of the guide groove 14, directly changing the lever arm of the force of the connecting rod 10 on the clamp handle 5, thereby further changing the clamping force of the clip 4 on the hair.

[0061] This embodiment is described using the first specific implementation of the adjustment structure 7.

[0062] The guide groove 14 can have several specific embodiments. The guide groove 14 is wavy, and the trough of the guide groove 14 is used to limit the rotation shaft 9. Alternatively, the guide groove 14 is planar, and a plurality of second grooves are provided on one long side of the guide groove 14 for limiting the rotation shaft 9. The specific shape of the guide groove 14 is not limited, but is described as wavy.

[0063] Specifically, the guide groove 14 of the connecting part 3 acts as a stop to restrict the rotating shaft 9, so that the rotating shaft 9 is located at one of the crests of the guide groove 14. If the guide groove 14 is planar, multiple grooves need to be provided on the long side of the section plane to engage the protrusion 15 of the push rod 13.

[0064] In this embodiment, the clamping structure 6 is rotatably connected to the main body 16 via a rotating shaft 9. One end of the connecting rod structure 8 is fixedly connected to the clamping structure 6. The adjusting structure 7 is connected to the rotating shaft 9 so that when the adjusting structure 7 is pushed, it drives the rotating shaft 9 to move within the range of the guide groove 14, changing the torque and thus changing the clamping force of the clamping structure 6 on the hair. By pushing the adjusting structure 7 to drive the rotating shaft 9, the lever arm is changed to change the torque, and the clamping force can be adjusted according to the gear position via the guide groove 14. This allows the clamping force of the clamping structure 6 on the hair to be easily magnified or reduced several times, so that personalized hair styling needs can be conveniently and effectively met by pushing the adjusting structure 7, bringing convenience to the user and enhancing the user experience.

[0065] The curling iron provided in this application has been described in detail above. Specific examples have been used to illustrate the specific implementation of this application. The description of the above embodiments is only for the purpose of helping to understand this application. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this application. Therefore, the content of this specification should not be construed as a limitation of this application.
