The silicone sleeve 22 can provide additional grip and comfort, allowing users to use the hair curler more conveniently and stably.

[0029] In this embodiment, a ring sleeve 23 is provided at one end of the protective shell 20 close to the accessory head 1 to enhance the stability of the protective shell 20. At the same time, the design of the ring sleeve 23 can also help the hair curler form a smooth appearance, making it more beautiful.

[0030] In this embodiment, a control circuit board 24 is also installed in the protective shell 20. The control circuit board 24 is electrically connected to the handle host 28, the accessory head 1 and the heating element 21. The control circuit board 24 is provided with a temperature control button 25 and a switch button 26. The operation of the heater is coordinated and controlled by the control circuit board 24. In addition, by setting the temperature control button 25, the user can choose the appropriate temperature according to his or her needs to perform the perm operation, thereby improving the user experience. The switch button 26 is set to realize the switching function of the curling iron.

[0031] The locking conductive structure includes an accessory head 1 and a handle main body 28. The accessory head 1 is provided with a buckling mechanism 2. There are two buckling mechanisms 2, which are symmetrically arranged on both sides of the accessory head 1. The buckling mechanism 2 is provided with a buckling groove 3; a locking yoke 4 is provided on the handle main body 28, and two locking blocks 5 are provided on the inner side of the lock yoke 4. The locking blocks 5 are symmetrically arranged on the edges of the lock yoke 4. Locking holes 6 are provided on both sides of the handle main body 28 for inserting the locking blocks 5. A convex key 8 is provided at the outer end of the lock yoke 4 to facilitate the user to press the lock yoke 4.

[0032] Specifically, when installing the accessory head 1, the user only needs to insert the accessory head 1 into the handle main body 28, and the lock block 5 will slide into the buckle groove 3 along the buckle mechanism 2. When the insertion is completed, the elastic member 1 7 will be compressed. After the insertion is completed, the elastic member 1 7 will recover, and the lock yoke 4 will pop up, and the lock yoke 4 will be combined with the handle main body 28. Figure 5 As shown, the locking block 5 moves leftward, helping the locking block 5 to be stably fixed in the buckle groove 3, thereby realizing a reliable connection between the accessory head 1 and the handle main body 28. When the accessory head 1 needs to be removed, the locking block 5 is connected to the handle main body 28. Figure 6 As shown, by simply pressing the convex key 8 on the lock yoke 4, the lock block 5 will move to the right and unlock, and the accessory head 1 can be removed. Compared with the prior art, the lock buckle structure of the utility model is easy to install and remove the accessory head 1, convenient for replacing different hair curling tools, simple in structure, and better meets user needs and market demands.

[0033] In this embodiment, a groove 9 is provided on the inner side of the convex key 8, a limit column 10 is provided on the groove 9, and a limit column 2 11 is provided on the outside of the handle main body 28. The limit column 10 is opposite to the limit column 2 11 and is on the same axial line. The two ends of the elastic member 7 are respectively mounted on the limit column 10 and the limit column 2 11.

[0034] Specifically, by putting the elastic member 7 on the limit column 10 and the limit column 2 11, the elastic member 7 can be prevented from accidentally sliding or loosening during the use of the lock yoke 4. By arranging the limit column 10 and the limit column 2 11 in the middle of the lock yoke 4 and one end of the handle main body 28 respectively, the elastic member 7 can provide balanced elastic force to the two ends of the lock yoke 4 to prevent the lock block 5 at one end from being stuck in the buckle groove 3, which makes it difficult to remove the accessory head 1. The groove 9 provides a space to accommodate the limit column 10 and further fix the elastic member 7.

[0035] In this embodiment, a handle slot 12 is provided at one end of the handle main body 28 for inserting the accessory head 1, and a conductive slot 13 and a conductive slot 30 are provided at the other end. A conductive needle 14 is installed inside the accessory head 1. The conductive slot 13 is used to insert the conductive needle 14. The conductive slot 30 is used to install the electrode needle 15 and the elastic member 16. One end of the electrode needle 15 is provided with a mounting cover 29 for fixing the electrode needle 15 and the elastic member 16 in the conductive slot 30. The elastic member 16 is sleeved on the outer periphery of the electrode needle 15 to allow it to have a certain degree of expansion and contraction. Process; the conductive slot 13 is connected to the conductive slot 30, the diameter of the conductive slot 13 is smaller than the diameter of the conductive slot 30, the electrode needle 15 is close to the conductive slot 13 and has a T-shaped big head end 31, the diameter of the T-shaped big head end 31 is larger than the diameter of the conductive slot 13 but smaller than the diameter of the conductive slot 30, when the handle host 28 is inserted into the accessory head 1, the conductive needle 14 passes through the conductive slot 13 and is tightly attached to the T-shaped big head end 31 of the electrode needle 15 and resists the compression elastic member 16, thereby realizing a stable electrical connection between the conductive needle 14 and the electrode needle 15.

[0036] Specifically, by providing the elastic member 16, the electrode needle 15 has the function of being reset and retractable. When the handle host 28 is inserted into the accessory head 1, a circuit connection will be established between the conductive needle 14 and the electrode needle 15. The elastic member 16 provides a certain elastic force to keep the electrode needle 15 in close contact, thereby ensuring the stability of the circuit connection. At the same time, when the user needs to remove or replace the accessory, by pressing the convex key 8, the lock block 5 will move to the right to unlock it, and the elastic member 16 will be restored, so that the accessory head 1 pops out a certain distance, making it easy for the user to take out the accessory head 1, thereby increasing the consumer's experience.

[0037] In this embodiment, slide grooves 17 are provided on both sides of the accessory head 1, and an accessory head shell 27 is installed on the accessory head 1. The slide grooves 17 are used to insert and fix the accessory head shell 27. In order to prevent the user's hands from accidentally sliding and touching the heating rod 19 and causing burns during use, the area of ​​the accessory head shell 27 gradually increases near the end of the heating rod 19. The accessory head 1 is also provided with a latch 18. The latch 18 is a planar structure, and the corresponding handle slot 12 is also provided with a planar feature matching the planar feature of the latch 18, which can prevent the accessory head 1 from being inserted incorrectly, and at the same time, it can prevent the accessory head 1 from rolling relative to the handle host 28 to cause the conductive needle 14 to be twisted, deformed or broken.

[0038] In a specific embodiment, when installing the accessory head 1, the user only needs to insert the accessory head 1 into the handle main body 28, and the lock block 5 will slide into the buckle groove 3 along the buckle mechanism 2. At the same time, the elastic member 7 will recover and bounce the lock yoke 4. Figure 5As shown, the lock block 5 moves to the left, helping the lock block 5 to be stably fixed in the buckle groove 3. In this way, the accessory head 1 is successfully installed on the handle main body 28. After the accessory head 1 is installed, the conductive needle 14 will push up the electrode needle 15, so that the elastic member 16 enters a compressed state. When the accessory head 1 needs to be removed, just press the convex key 8 on the lock yoke 4, as shown in FIG. Figure 6 As shown, the locking block 5 will move to the right and unlock. At the same time, the elastic member 16 will recover and drive the accessory head 1 to bounce up a certain distance, so that the accessory head 1 can be easily removed. The structure is simple, and the accessory head 1 is easy to install and disassemble, so it is convenient to replace different curling tools.

[0039] The above-described implementation methods of the utility model do not constitute a limitation on the protection scope of the utility model. Any modification, equivalent replacement and improvement made within the spirit and principle of the utility model shall be included in the protection scope of the claims of the utility model.
