[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] The core of the present invention is to provide an adjustable diameter reel. During use, when the outer diameter of the reel changes, since the second component is rotatably arranged on the first component, and the adjacent first components are in abutment with the second component, a gap between the adjacent first components and the second components is avoided to prevent impurities from entering, thereby improving the circumferential sealing effect of the reel during the diameter change process.

[0050] Another core of the present invention is to provide a hair curler comprising the above-mentioned adjustable diameter roller.

[0051] Please refer to Figure 1-18 .

[0052] This specific embodiment discloses an adjustable diameter reel, including a mounting assembly and at least two heat conducting members 100 mounted on the mounting assembly;

[0053] The heat conducting member 100 is overlapped end to end along the circumferential direction to form a closed ring; the heat conducting member 100 includes a first member 101 and a second member 102 rotatably disposed on the first member 101;

[0054] Within the diameter variation range of the adjustable diameter reel, the first component 101 and the second component 102 of adjacent heat conductive members 100 abut against each other at non-end positions and always have an overlapping covering area in the circumferential direction, or the end of the first component 101 abuts against the end of the second component 102.

[0055] It should be noted that, during the rotation of the first component 101 relative to the second component 102 , a snap-in position may be provided so that the first component 101 is fixed when it rotates to a preset angle relative to the second component 102 .

[0056] When the outer diameter of the adjustable diameter reel is not adjusted to the maximum, the non-end position of the first component 101 is in abutment with the non-end position of the second component 102, and there is always an overlapping covering area in the circumferential direction; when the outer diameter of the adjustable diameter reel is adjusted to the maximum, the end of the first component 101 is in abutment with the end of the second component 102, and at this time, there is no overlapping area between the first component 101 and the second component 102 in the circumferential direction.

[0057] In the process of using the adjustable diameter reel provided by the present invention, when the diameter of the reel needs to be adjusted, the heat conductive member 100 can be moved relative to the mounting assembly, specifically by movement and / or rotation, or other forms of movement, which are determined according to actual conditions. When the outer diameter of the adjustable diameter reel changes, the circumferential overlapping portion of the first component 101 and the second component 102 of adjacent heat conductive members 100 changes, thereby increasing or decreasing the outer diameter of the closed loop formed by the heat conductive member 100. During this process, the adjacent first component 101 and the second component 102 are in abutment with each other and always overlap in the circumferential direction.

[0058] Compared with the prior art, when the diameter of the reel changes, the second component 102 maintains contact with the adjacent first component 101, avoiding the appearance of a gap between the adjacent first component 101 and the second component 102 to allow impurities to enter, thereby improving the circumferential sealing effect of the reel during the diameter change process, thereby improving the comfort of use of the reel and effectively extending the service life of the reel.

[0059] In a specific embodiment, an adjustable diameter reel is disclosed, including a mounting assembly and at least two heat conducting members 100;

[0060] The heat conducting member 100 is overlapped end to end along the circumferential direction to form a closed ring; the heat conducting member 100 includes a support member 104, a first member 101, and a second member 102 rotatably connected to the first member 101 around a second rotation axis 1021;

[0061] The first component 101 is rotatably disposed on the mounting assembly around a first rotation axis 1011. Within the rotation angle range of the first component 101, the first component 101 and the second component 102 of adjacent heat conducting members 100 always have an overlapping covering area in the circumferential direction; the support member 104 is used to support the second component 102 so that it abuts against the adjacent first component 101;

[0062] The first rotating shaft 1011 of the first component 101 is parallel to and spaced from the central axis 103 of the adjustable diameter reel.

[0063] It should be noted that the first rotating axis 1011 of the first component 101 mentioned in this specific embodiment can be coplanar and parallel with the central axis 103 of the adjustable diameter reel, or the first rotating axis 1011 of the first component 101 can be non-coplanar with the central axis 103 of the adjustable diameter reel, which is determined according to actual conditions.

[0064] It should be noted that in this specific embodiment, the number of the heat conducting members 100 can be two or more, which is determined according to actual conditions and will not be elaborated herein.

[0065] In the process of using the adjustable diameter reel provided in this specific embodiment, when the diameter of the reel needs to be adjusted, the heat conductive member 100 can be rotated to rotate the heat conductive member 100 relative to the mounting assembly. Since the first rotating axis 1011 of the heat conductive member 100 is parallel to the central axis 103 of the reel and is spaced apart, during the rotation of the heat conductive member 100, the circumferential overlapping portion of the first component 101 and the second component 102 of adjacent heat conductive members 100 changes, thereby increasing or decreasing the outer diameter of the closed loop formed by the heat conductive member 100.

[0066] Compared with the prior art, due to the setting of the support member 104, when the diameter of the reel changes, the second component 102 maintains contact with the adjacent first component 101, avoiding the appearance of a gap between the adjacent first component 101 and the second component 102 to allow impurities to enter, thereby improving the circumferential sealing effect of the reel during the diameter change process, thereby improving the comfort of use of the reel and effectively extending the service life of the reel.

[0067] In a specific embodiment, if Figure 5 As shown, the second component 102 is parallel and non-coplanar with respect to the second rotation axis 1021 of the first component 101, the first rotation axis 1011 of the first component 101, and the central axis 103 of the adjustable diameter reel. The second component 102 is parallel and coplanar with respect to any two of the second rotation axis 1021 of the first component 101, the first rotation axis 1011 of the first component 101, and the central axis 103 of the adjustable diameter reel.

[0068] During use, if Figure 6 As shown, the angle a1 between the line connecting the first rotating shaft 1011 and the central axis 103 of the adjustable diameter reel and the line connecting the second rotating shaft 1021 and the central axis 103 of the adjustable diameter reel is the largest. The heat conducting member 100 is rotated to increase the outer diameter of the closed loop formed by the heat conducting member 100. During this process, the angle between the line connecting the first rotating shaft 1011 and the central axis 103 of the adjustable diameter reel and the line connecting the second rotating shaft 1021 and the central axis 103 of the adjustable diameter reel gradually decreases. When the second member 102 is relative to the second rotating shaft 101 of the first member 101, the outer diameter of the closed loop formed by the heat conducting member 100 increases. When the axis 1021, the first rotation axis 1011 of the first component 101, and the central axis 103 of the adjustable diameter reel are coplanar, the outer diameter of the closed loop formed by the heat-conducting member 100 is the largest; however, in the actual setting process, in order to avoid the heat-conducting member 100 from rotating excessively, and the outer diameter of the closed loop formed by the heat-conducting member 100 itself is not required to have a small range of change, generally when the second rotation axis 1021 of the second component 102 relative to the first component 101, the first rotation axis 1011 of the first component 101, and the central axis 103 of the adjustable diameter reel are close to being coplanar, such as Figure 7As shown, the angle between the line connecting the first rotating axis 1011 and the central axis 103 of the adjustable diameter drum and the line connecting the second rotating axis 1021 and the central axis 103 of the adjustable diameter drum is a2, and the outer diameter of the closed ring formed by the heat conducting member 100 reaches the maximum.

[0069] In a specific embodiment, the support member 104 is an elastic member, and one end of the elastic member abuts against the first member 101 , and the other end of the elastic member abuts against the second member 102 .

[0070] During use, when the heat-conducting member 100 rotates around the first rotation axis 1011, the circumferential overlapping position of the adjacent first components 101 and the second components 102 changes, and the angle between the adjacent first components 101 and the second components 102 changes. Under the action of the elastic force of the support member 104, the second component 102 in the same heat-conducting member 100 will rotate around the second rotation axis 1021 relative to the first component 101, so that the adjacent first components 101 and the second components 102 always maintain a contact state, avoiding the formation of a gap between the adjacent first components 101 and the second components 102.

[0071] Specifically, Figure 6 As shown, the support member 104 is a torsion spring, one end of which abuts against the first component 101 and the other end abuts against the second component 102 . Under the elastic force of the torsion spring, the second component 102 is supported to always keep in contact with the adjacent first component 101 .

[0072] In a specific embodiment, if Figure 5 As shown, the first component 101 is provided with a limiting portion 1013 for limiting the rotation angle of the second component 102 relative to the first component 101, and the limiting portion 1013 is provided at the connection between the first component 101 and the second component 102. The first component 101 is provided with a recess for installing the second rotation axis 1021, and the opening edge of the recess is the limiting portion 1013; during the rotation of the second component 102 relative to the first component 101, after the second component 102 rotates to contact the limiting portion 1013, it is restricted by the limiting portion 1013 and cannot continue to rotate relative to the first component 101.

[0073] In this specific embodiment, the setting of the limiting portion 1013 can effectively limit the rotation angle of the second component 102 relative to the first component 101 , thereby preventing the adjacent second component 102 from being separated from the first component 101 under the supporting force of the support member 104 .

[0074] like Figure 6 , 7 As shown, in a specific embodiment, the outer side surfaces of the first component 101 and the second component 102 are both arc surfaces, and a gap is set between the inner arc surface of the first component 101 and the outer arc surface of the adjacent second component 102.

[0075] The outer side surfaces of the first component 101 and the second component 102 are both configured as arc surfaces, so that the outer surface of the closed ring formed by the heat conducting member 100 can be close to a cylindrical surface.

[0076] It should be noted that the first component 101 and the second component 102 mentioned in the present application document refer to structures having a certain length dimension in the circumferential direction, and do not simply refer to the end portions.

[0077] In this specific embodiment, the inner curved surface of the first component 101 can be arranged in contact with the outer curved surface of the adjacent second component 102, which can effectively avoid the formation of a gap between the inner curved surface of the first component 101 and the outer curved surface of the adjacent second component 102, thereby preventing dust and other impurities from entering the interior of the reel.

[0078] Of course, a gap may be provided between the inner arc surface of the first component 101 and the outer arc surface of the adjacent second component 102 to reduce the friction force generated by friction between adjacent heat conductive components 100 during the rotation of the heat conductive component 100, thereby facilitating the rotation of the heat conductive component 100.

[0079] Based on the above embodiment, the inner diameter of the arc surface of the first component 101 can be made larger than the outer diameter of the arc surface of the second component 102, so that the first component 101 and the second component 102 can overlap better and increase the rotatable angle of the heat conducting member 100 as much as possible.

[0080] In a specific embodiment, the first component 101 can completely cover the second component 102. Figure 6 As shown, the first component 101 completely covers the second component 102 , and the outer diameter of the closed ring formed by the heat conducting element 100 at this time is the outer diameter of the arc surface of the first component 101 .

[0081] In this specific embodiment, when the first component 101 completely covers the second component 102, the closed loop formed by the heat conducting member 100 can be cylindrical to meet the requirement that the external object is wound around the reel to form a circular ring.

[0082] Preferably, as shown in the figure, the first rotating shaft 1011 can be set at a position of the first component 101 close to the end of the second component 102, so that during the rotation of the heat conductive component 100, the outer diameter of the closed loop formed by the heat conductive component 100 changes greatly, thereby expanding the diameter change range of the reel.

[0083] In a specific embodiment, all first components 101 have the same distance from the first rotation axis 1011 of the mounting assembly to the central axis 103 of the adjustable diameter reel; all second components 102 have the same distance from the second rotation axis 1021 of the first component 101 to the central axis 103 of the adjustable diameter reel;

[0084] And / or, all first components 101 are evenly distributed along the circumferential direction relative to the first rotation axis 1011 of the mounting assembly, and all second components 102 are evenly distributed along the circumferential direction relative to the second rotation axis 1021 of the first component 101 .

[0085] like Figure 6 , 7 As shown, the adjustable diameter reel is provided with three heat-conducting members 100, the first rotating axes 1011 of the heat-conducting members 100 are at the same distance from the central axis 103 of the reel, the second rotating axes 1021 of the heat-conducting members 100 are at the same distance from the central axis 103 of the reel, and the first rotating axes 1011 of each heat-conducting member 100 are evenly distributed along the circumferential direction, and the second rotating axes 1021 of each heat-conducting member 100 are evenly distributed along the circumferential direction; during the rotation of the heat-conducting member 100, the overlapping parts of the adjacent first components 101 and the second components 102 change in the same manner along the circumferential direction, so that the shape of the reel changes evenly in the circumferential direction.

[0086] It should be noted that during use, the heat conductive member 100 can be driven to rotate by an electrically controlled power member. Specifically, it can also include an electrically controlled power member that drives the heat conductive member 100 to rotate relative to the mounting assembly, and the electrically controlled power member is connected to the heat conductive member 100 via a transmission structure.

[0087] During use, by controlling the rotation angle and rotation direction of the electrically-controlled power component, the rotation angle and rotation direction of the heat-conducting component 100 are controlled, so that multiple heat-conducting components 100 can be rotated synchronously in the same direction; for example, the electrically-controlled power component is a motor, and the output shaft of the motor is connected to a gear, and the outer periphery of the gear is respectively meshed with multiple peripheral gears, and the central axes 103 of the multiple peripheral gears are respectively connected to the first rotating shaft 1011 of the heat-conducting component 100 to drive the heat-conducting component 100 to rotate synchronously in the same direction; of course, it can also be other transmission connection methods that meet the requirements, which are determined according to actual conditions.

[0088] In addition, the rotation of the heat conducting member 100 may also be adjusted by the adjusting component 204 , which may be considered as operating the adjusting component 204 , or the adjusting component 204 may be driven to rotate by an electrically controlled power member, which is specifically determined according to actual conditions.

[0089] In a specific embodiment, the mounting assembly includes a first component assembly 201 and a second component assembly 202 respectively arranged at both ends of the axial direction of the heat conductor 100, and at least one of the first component assembly 201 and the second component assembly 202 is provided with an adjustment assembly 204 for driving the heat conductor 100 to rotate an angle.

[0090] In a specific embodiment, if Figure 2As shown, the mounting assembly includes a central connecting rod, a first component assembly 201 and a second component assembly 202, one end of the central connecting rod 203 is rotatably connected to the first component assembly 201, and the other end is rotatably connected to the second component assembly 202;

[0091] The first rotating shaft 1011 includes a first pin shaft protruding from one end of the heat conductive member 100 along the axial direction and a second pin shaft protruding from the other end of the heat conductive member 100 along the axial direction and coaxial with the first pin shaft. The first pin shaft is rotatably installed on the first component assembly 201, and the second pin shaft is rotatably connected to the second component assembly 202.

[0092] In the specific assembly, such as Figure 2 As shown, the first component assembly 201 can be fixedly connected to the handle 300, and the end of the second component assembly 202 can be rotatably installed on the adjustment assembly 204. During the rotation of the adjustment assembly 204, the adjustment assembly 204 drives the heat conductor 100 to rotate relative to the second component assembly 202 and the first component assembly 201.

[0093] like Fig.14 As shown, the first component assembly 201 is provided with a first mounting hole 2011, the first pin is rotatably disposed in the first mounting hole 2011, and the first component assembly 201 is provided with a first matching hole 2012, and one end of the central connecting rod 203 is inserted into the first matching hole 2012, so that the handle 300 connecting piece is fixedly connected to the central connecting rod 203. Fig.13 As shown, the second component assembly 202 is provided with a second mounting hole 2021, and the second pin shaft is rotatably arranged in the second mounting hole 2021; the second component assembly 202 is provided with a second matching hole 2022, and the other end of the center connecting rod 203 is inserted into the second matching hole 2022, so that the adjusting connecting piece is fixedly connected to the center connecting rod 203.

[0094] In a specific embodiment, the adjustment component 204 includes a rotary cap 2041 and a rotating piece 2042 fixed to the rotary cap 2041. The rotary cap 2041 is rotatably arranged relative to the mounting component. The rotating piece 2042 is provided with guide grooves 20421 distributed along the circumferential direction. The end of the heat conducting member 100 facing the adjustment component 204 is provided with a convex shaft 1012, and the convex shaft 1012 is inserted into the guide groove 20421. The guide groove 20421 has radial and circumferential extensions along the rotating piece 2042.

[0095] When the rotary cap 2041 is rotated, the convex shaft 1012 slides along the guide groove 20421 relative to the rotating sheet 2042, so that the heat conducting member 100 rotates relative to the mounting assembly.

[0096] The convex shaft 1012 can be a cylindrical shaft, a square shaft, or a convex block, etc., which is determined according to actual conditions.

[0097] The guide groove 20421 may be replaced by a guide rail or other structure, which may be determined based on actual conditions.

[0098] like Fig.17 As shown, the screw cap 2041 is provided with a snap-fit ​​protrusion 20411. Fig.18 As shown, the rotating piece 2042 is provided with a clamping slot 20422 , and the rotating piece 2042 is clamped and matched with the clamping protrusion 20411 through the clamping slot 20422 , so that the rotating piece 2042 is fixedly arranged relative to the rotating cap 2041 .

[0099] like Figure 2 As shown, the adjustment assembly 204 includes a rotary cap 2041, a rotating piece 2042 fixed to the rotary cap 2041, and a mounting bracket 2043 fixed to the central connecting rod 203 of the mounting assembly, and a guide groove 20421 is provided on the rotating piece 2042; Fig.18 As shown, from one end of the guide groove 20421 to the other end, while having a circumferential extension, the guide groove 20421 gradually approaches the position close to the central axis 103 line of the rotating plate 2042. A gear adjustment groove can be set on the mounting bracket 2043, and a movable adjustment member can be set on the rotary cap 2041, and the adjustment member can be moved to a position where the adjustment groove is engaged or released. When the adjustment member is engaged with the adjustment groove. The rotary cap 2041 is fixed relative to the mounting assembly and cannot drive the heat conductive member 100 to rotate; when the adjustment member is released from the engagement with the adjustment groove, the rotary cap 2041 can drive the heat conductive member 100 to rotate.

[0100] During specific use, the rotary cap 2041 is rotated, and the rotary cap 2041 drives the rotating plate 2042 to rotate. During the rotation of the rotating plate 2042, the heat conductive member 100 will be driven to rotate. Since the convex shaft 1012 is inserted into the guide groove 20421, the convex shaft 1012 will slide along the guide groove 20421, thereby limiting the rotation trajectory of the heat conductive member 100; the length of the guide groove 20421 limits the rotation angle range of the heat conductive member 100; it should be noted that the setting position of the convex shaft 1012 is different from the setting position of the first rotating shaft 1011.

[0101] Compared with the prior art, the adjustable diameter reel provided by the present invention can adjust the rotation angle and rotation direction of the heat conducting member 100 by rotating the rotary cap 2041 during use, which is convenient to use.

[0102] In addition to the above-mentioned adjustable diameter reel, the present invention further provides a curling iron 1000 including a handle 300 and the adjustable diameter reel disclosed in the above-mentioned embodiment. The structures of other parts of the curling iron 1000 are referred to the prior art and will not be described in detail herein.

[0103] The words “first” and “second” in the first rotation axis 1011 and the second rotation axis 1021 , the first mounting hole 2011 and the second mounting hole 2021 , the first component 101 and the second component 102 mentioned in the present application document are only for distinguishing the different positions and there is no order of precedence.

[0104] In this specification, each embodiment is described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referred to each other. Any combination of all embodiments provided by the present invention is within the protection scope of this invention and will not be described in detail here.
