[0050] Figure 3 is an exploded structural schematic diagram of a hair curler shown according to an exemplary embodiment. Figure 4 is a structural schematic diagram of a heat conducting member of a hair curler in a first state shown according to an exemplary embodiment. Figure 5 is a structural schematic diagram of a heat conducting member of a hair curler in a second state shown according to an exemplary embodiment

[0051] In an exemplary embodiment of the present disclosure, as Figure 1 and Figure 3 shown, the heat conducting member 40 may include a plurality of movable pieces 401, for example, it may include a plurality of first movable pieces 411 and second movable pieces 412. When the heat conducting member 40 is in the first state, the plurality of first movable pieces 411 may be connected in sequence to form a receiving cavity, and the second movable piece 412 may be disposed in the receiving cavity.

[0052] In an exemplary embodiment of the present disclosure, there may be four first movable pieces 411 having the same shape and size, and the four first movable pieces 411 are symmetrically arranged.

[0053] In an exemplary embodiment of the present disclosure, there may be four second movable pieces 412 having the same shape and size, and the four second movable pieces 412 are symmetrically arranged. The second movable pieces 412 and the first movable pieces 411 may be arranged at intervals.

[0054] In an exemplary embodiment of the present disclosure, as Figure 2 shown, the hair curler 1 may further be provided with a heat insulating sheet 402. The heat insulating sheet 402 may be disposed inside the heat conducting member 40 to play a heat preservation role, thereby improving the heating efficiency. In some embodiments, the heat insulating sheet 402 may be disposed inside the first movable piece 411. In some embodiments, the heat insulating sheet 402 may be disposed inside the second movable piece 412

[0055] As Figure 4 shown, when the heat conducting member 40 is in the first state, during use, the hair is wound around the outside of the receiving cavity formed by the surrounding of the first movable pieces 411, and the second movable piece 412 is inside the receiving cavity, and the second movable piece 412 does not contact the hair.

[0056] In an exemplary embodiment of the present disclosure, as Figure 4 and Figure 5 shown, the outer surface of the second movable piece 412 may be provided with a convex platform 413 protruding outward. Regarding the inside and outside, the inside of the hair curler 1 is the inside, for example, the rotating shaft 30 may be considered the inside, and components such as the heat conducting member 40 that can be directly seen can be called exposed to the outside.

[0057] As Figure 4 and Figure 5 shown, when the heat conducting member 40 is in the first state, the convex platform 413 abuts against the inner surface 414 of the first movable piece 411. When the heat conducting member 40 is in the second state, the convex platform 413 is flush with the outer surface 415 of the first movable piece 411.

[0058] As Figure 4 and Figure 5As shown, the boss 413 can have a smooth transition so that during the state change process of the heat conducting member 40, the boss 413 can move smoothly and stably relative to the first movable piece 411 to complete the state change.

[0059] As Figure 1 and Figure 5 shown, when the heat conducting member 40 is in the second state, two adjacent first movable pieces 411 among the plurality of first movable pieces 411 are connected by the second movable piece 412 to form a receiving cavity. That is, the second movable piece 412 is respectively connected to the adjacent first movable pieces 411.

[0060] When the heat conducting member 40 is in the second state, during use, the hair is wound around the outside of the receiving cavity formed by the first movable piece 411 and the second movable piece 412, and both the first movable piece 411 and the second movable piece 412 can contact the hair.

[0061] In the exemplary embodiment of the present disclosure, the first movable piece 411 can be a heat conducting piece. For example, the first movable piece 411 can be a metal piece, such as an aluminum piece. In the present disclosure, the first movable piece 411 can be a heat conducting piece body, or can be a structure including a bracket and a heat conducting piece, and the bracket is used for placing the heat conducting piece.

[0062] In the exemplary embodiment of the present disclosure, the second movable piece 412 can be a plastic piece. For example, the second movable piece 412 can be made of a heat resistant plastic material, such as Polyphenylene sulfide (PPS). In the present disclosure, the second movable piece 412 can be a plastic piece body, or can be a structure including a bracket and a plastic piece, and the bracket is used for placing the plastic piece.

[0063] In the embodiment of the present disclosure, the first movable piece 411 conducts heat, and the second movable piece 412 does not conduct heat. In the first state, the second movable piece 412 is located inside the receiving cavity, and since it does not conduct heat, it will not affect other components inside the receiving cavity. In the second state, the second movable piece 412 is located between two adjacent first movable pieces 411, forming an effect of alternating hot and cold, and forming a better hair curling effect.

[0064] In the exemplary embodiment of the present disclosure, when the heat conducting member 40 is in the first state, the diameter of the heat conducting member 40 in the radial direction of the rotating shaft 30 can be 28 - 32 mm. For example, when the heat conducting member 40 is in the first state, the diameter of the heat conducting member 40 in the radial direction of the rotating shaft 30 can be 32 mm.

[0065] In an exemplary embodiment of the present disclosure, when the heat conducting member 40 is in the second state, the diameter of the heat conducting member 40 in the radial direction of the rotating shaft 30 may be 32 - 40 mm. For example, when the heat conducting member 40 is in the second state, the diameter of the heat conducting member 40 in the radial direction of the rotating shaft 30 may be 38 mm.

[0066] As Figures 3 to 5 shown, the heat conducting member 40 may include a protruding member 403, and the protruding member 403 is provided at one end (front end) of the heat conducting member 40 facing the driving portion 10. The protruding member 403 may be provided inside the movable piece 401. For example, inside the movable piece 401, that is, a supporting portion 404 is formed inside the movable piece 401 facing the accommodating cavity, and the protruding member 403 may be provided at the supporting portion 404.

[0067] As Figures 3 to 5 shown, the driving portion 10 may be sleeved on the limiting member 20, and the driving portion 10 may drive the limiting member 20 to rotate so that the protruding member 403 disposed in the limiting groove moves relative to the limiting groove, and further may drive the movable piece 401 to move, completing the switching between the first state and the second state.

[0068] In the present disclosure, as Figure 2 shown, in the axial direction of the rotating shaft 30, the limiting member 20 may be provided between the driving portion 10 and the heat conducting member 40. For example, the limiting member 20 may be provided at the front end of the heat conducting member 40. However, the present disclosure is not limited thereto. In some embodiments, the hair curler 1 may be provided with a pair of limiting members, and the pair of limiting members are respectively provided at both ends of the heat conducting member 40, that is, may be provided at the front end and the rear end of the heat conducting member 40.

[0069] As Figure 2 shown, the limiting member 20 may be provided at the front end of the heat conducting member 40, and the limiting member located at the front end of the heat conducting member 40 may be referred to as the front limiting member. The hair curler 1 may further include a rear limiting member 52, and the rear limiting member 52 may be located at the rear end of the heat conducting member 40.

[0070] In the present disclosure, the setting position and number of the limiting members are not limited. The limiting member may be provided only at the front end of the heat conducting member, or may be provided only at the rear end of the heat conducting member, or the heat conducting member may be provided at both the front end and the rear end of the heat conducting member.

[0071] Hereinafter, the limiting member 20 located at the front end of the heat conducting member 40 will be taken as an example for detailed description. The rear limiting member 52 located at the rear end of the heat conducting member 40 may have the same or similar features as the limiting member 20, and will not be described in detail.

[0072] It should be noted that in some embodiments, the limiting member is only provided at the rear end of the heat conducting member, and the driving portion may also be located at the rear end of the heat conducting member. In some embodiments, limiting members are provided at both the front end and the rear end of the heat conducting member, and the driving portion may also be located at the front end or the rear end of the heat conducting member to drive the limiting member and the rotating shaft, thereby driving the heat conducting member to change its state.

[0073] In the present disclosure, as Figure 1 and Figure 3 shown, the limiting member 20 may include a first limiting member 21 and a second limiting member 22 which are stacked on each other. In the axial direction of the rotating shaft 30, the second limiting member 22 is located between the first limiting member 21 and the heat conducting member 40. In the axial direction of the rotating shaft 30, the first limiting member 21 may be located between the driving portion 10 and the second limiting member 22.

[0074] As Figures 3 to 5 shown, the protruding member 403 may pass through the limiting groove of the limiting member 20. For example, the protruding member 403 may pass through the first limiting groove 201 of the first limiting member 21 and the second limiting groove 202 of the second limiting member 22 respectively.

[0075] In the present disclosure, the first limiting member 21 is provided with a first limiting groove 201, and the first limiting groove 201 may extend from the center of the first limiting member 21 towards the circumferential side. The first limiting groove 201 may be provided in plurality, and in some embodiments, the plurality of first limiting grooves 201 may be evenly distributed on the first limiting member 21.

[0076] In the present disclosure, the second limiting member 22 is provided with a second limiting groove 202, and the second limiting groove 202 may extend from the center of the second limiting member 22 towards the circumferential side. The second limiting groove 202 may be provided in plurality, and in some embodiments, the plurality of second limiting grooves 202 may be evenly distributed on the second limiting member 22.

[0077] In the present disclosure, a part of the first limiting groove 201 and a part of the second limiting groove 202 overlap, and the protruding member 403 may pass through the overlapping part.

[0078] In the present disclosure, the shapes of the first limiting groove 201 and the second limiting groove 202 in a plane are set to be different. With such a setting, when the protruding member 403 is inserted through the first limiting groove 201 and the second limiting groove 202, due to the different shapes of the two, they can play a role of mutual limitation. For example, when the protruding member 403 moves relative to the limiting groove under an external force, then when there is no external force, there is a tendency of relative movement between the protruding member 403 and the limiting groove. At this time, since the protruding member 403 passes through the overlapping part of the first limiting groove 201 and the second limiting groove 202 at the same time, and the shapes of the two are different, if there is a tendency of relative movement between the protruding member 403 and the first limiting groove 201, the second limiting groove 202 can limit the movement of the protruding member 403, and vice versa.

[0079] In the present disclosure, the shape of the first limiting groove 201 in a plane can be arc-shaped. The shape of the second limiting groove 202 in a plane can be strip-shaped. However, the present disclosure is not limited thereto, and the shapes of the first limiting groove 201 and the second limiting groove 202 can be interchanged, and can also be any other shape.

[0080] In the present disclosure, the moving trajectory of the protruding member 403 can match the shape of the second limiting groove 202. For example, the moving trajectory of the protruding member 403 can be the same as the shape of the second limiting groove 202.

[0081] Figure 6 It is a schematic structural diagram of a limiting member of a hair curler in a first state shown according to an exemplary embodiment. Figure 7 It is a schematic structural diagram of a limiting member of a hair curler in a second state shown according to an exemplary embodiment.

[0082] As Figure 6 described, when the heat conducting member 40 is in the first state, the protruding member 403 can be inserted through the first limiting groove 201 and the second limiting groove 202, and can be located at one end of the first limiting groove 201 or one end of the second limiting groove 202, that is, in the first state, the protruding member 403 and the limiting groove can no longer move relatively. Or, in the first state, the protruding member 403 can be located at one end of the first limiting groove 201 and can be located at one end of the second limiting groove 202.

[0083] As Figure 7 , when the heat conducting member 40 is in the second state, the protruding member 403 can be inserted through the first limiting groove 201 and the second limiting groove 202, and can be located at the other end of the first limiting groove 201 or the other end of the second limiting groove 202, that is, in the second state, the protruding member 403 and the limiting groove can no longer move relatively. Or, in the second state, the protruding member 403 can be located at the other end of the first limiting groove 201 and can be located at the other end of the second limiting groove 202.

[0084] It should be noted that in the present disclosure, the heat conducting member 40 may also have other states between the first state and the second state. In these states, the protruding member 403 may be located in the middle of the limiting groove instead of the end, that is, there is still a tendency for relative movement between the protruding member 403 and the limiting groove. However, in such a state, since the shapes of the first limiting groove 201 and the second limiting groove 202 are different and can play a role of mutual limitation, the protruding member 403 and the limiting groove still cannot move relative to each other. Thus, the heat conducting member 40 can be fixed in this state to provide users with more choices of curling diameters.

[0085] In an exemplary embodiment of the present disclosure, as Figure 3 shown, the driving member may include a driving portion 10, and the driving portion 10 may be sleeved on the second limiting member 22.

[0086] As Figures 1 to 3 shown, the driving portion 10 may be located at the foremost end of the hair curler 1. The driving portion 10 may function as a protective cap. The driving portion 10 is provided with a perforation through which the rotating shaft 30 can pass. In some embodiments, the driving portion 10 may have a shape that is smaller at the front and larger at the back as Figures 1 to 3 shown, or may have a shape that is the same before and after, or smaller at the front and larger at the back.

[0087] As Figure 2 and Figure 3 shown, a first connecting portion 101 may be provided on the inner side of the driving portion 10, and a second connecting portion 203 may be provided on the circumferential side of the limiting member 20. The first connecting portion 101 and the second connecting portion 203 may cooperate with each other so that the driving portion 10 drives the limiting member 20 to rotate.

[0088] As Figure 3 shown, the first connecting portion 101 may be a groove, and the second connecting portion 203 may be a protrusion. However, the present disclosure is not limited thereto. In some embodiments, the shapes of the first connecting portion 101 and the second connecting portion 203 may be interchanged, or may be any other shape.

[0089] In the present disclosure, the first connecting portion 101 and the second connecting portion 203 may be snap-connected to each other.

[0090] In the present disclosure, the second connecting portion 203 may be provided on the second limiting member 22. As Figure 2 and Figure 3 shown, a first connecting portion 101 may be provided on the inner side of the driving portion 10, and a second connecting portion 203 may be provided on the circumferential side of the second limiting member 22. The first connecting portion 101 and the second connecting portion 203 may cooperate with each other so that the driving portion 10 drives the second limiting member 22 to rotate.

[0091] It should be noted that the present disclosure is not limited thereto. In some embodiments, the second connecting portion 203 may also be provided on the second limiting member 22.

[0092] In an exemplary embodiment of the present disclosure, the hair curler 1 may include a rotating shaft 30. The first limiting member 21 and the second limiting member 22 may be sleeved on the rotating shaft 30. The driving portion 10 may be sleeved on the rotating shaft 30. Rotating the driving portion 10 can drive the rotating shaft 30 and the first limiting member 21 to rotate.

[0093] As Figure 1 and Figure 3 shown, the rotating shaft 30 may include a guiding portion 301. The guiding portion 301 may pass through the driving portion 10, the first limiting member 21 and the second limiting member 22.

[0094] In an exemplary embodiment of the present disclosure, as Figure 1 and Figure 3 shown, the first limiting member 21 may be provided with a third limiting groove 204. The guiding portion 301 may pass through the third limiting groove 204. The third limiting groove 204 may be adapted to the guiding portion 301 so that the rotating shaft and the first limiting member rotate together. For example, the first limiting member 21 drives the rotating shaft 30 to rotate together, or the rotating shaft 30 drives the first limiting member 21 to rotate together, or the driving portion 10 drives the rotating shaft 30 and the first limiting member 21 to rotate together at the same time.

[0095] For example, the guiding portion 301 may be concave, and the inside of the third limiting groove 204 may protrude to match the concave guiding portion 301.

[0096] In an exemplary embodiment of the present disclosure, as Figure 1 and Figure 3 shown, the rotating shaft 30 is cylindrical, the guiding portion 301 is a platform formed by concave cylindrical, and the inside of the third limiting groove 204 also has a corresponding platform. The platform of the guiding portion 301 and the third limiting groove 204 may abut, so that the rotating shaft 30 and the first limiting member 21 rotate together.

[0097] When the first limiting member 21 rotates, the protruding member 403 may move within the first limiting groove 201, causing the heat conducting member 40 to change its state.

[0098] In an exemplary embodiment of the present disclosure, as Figure 1 and Figure 3As shown, the second limiting member 22 is provided with a fourth limiting groove 205. The guiding portion 301 can pass through the fourth limiting groove 205, and the fourth limiting groove 205 can be adapted to the guiding portion 301 so that the second limiting member 22 and the rotating shaft 30 are separated from each other. For example, the second limiting member 22 does not rotate with the rotation of the rotating shaft 30, and the rotating shaft 30 does not rotate with the rotation of the second limiting member 22. For example, the guiding portion 301 can be concave, and the inside of the fourth limiting groove 205 can be circular without contacting the guiding portion 301. That is, the guiding portion 301 can rotate independently in the fourth limiting groove 205 without contacting the second limiting member 22.

[0099] In the present disclosure, the first limiting member 21 and the second limiting member 22 can pass through the rotating shaft 30. The diameter of the first limiting member 21 can be smaller than that of the second limiting member 22. In the present disclosure, when the first limiting member 21 rotates with the driving portion 10, the second limiting member 22 may not rotate.

[0100] However, the present disclosure is not limited thereto. In some embodiments, it can also be set that when the second limiting member 22 rotates with the driving portion 10, the first limiting member 21 may not rotate.
