[0041] In order to achieve different curling effects, the heat-conducting sleeve of the detachable curling iron can be removed and replaced, so that different heat-conducting sleeves can produce different curls. However, the existing detachable curling iron usually uses a threaded part to achieve a detachable connection. The threaded part connection method requires a long time for the user to disassemble. At the same time, the thread is prone to slippage during long-term and improper use, which makes it more inconvenient to disassemble the curling iron.

[0042] Please refer to Figure 1 and Figure 2 In order to solve the problem that the existing detachable curling iron is inconvenient to disassemble, the first embodiment of the utility model provides a curling device, which includes a body 11 and an end portion 21. The body 11 includes a rotating shaft 112 and a hollow heat-conducting sleeve 111 with an opening at one end. The heat-conducting sleeve 111 is sleeved on the rotating shaft 112. The heat-conducting sleeve 111 and the rotating shaft 112 are detachably connected;

[0043] A first fastener 113 is disposed on one end of the rotating shaft 112 close to the opening, and a second fastener 211 is disposed on the end portion 21 corresponding to the first fastener 113;

[0044] The rotating shaft 112 and the end portion 21 are buckled and connected via the first buckle 113 and the second buckle 211 , and the outer end surface of the end portion 21 close to the second buckle 211 abuts against the heat-conducting sleeve 111 .

[0045] The first clip 113 and the second clip 211 are clipped together to realize a detachable connection between the end portion 21 and the body 11. After the clip connection, the end portion 21 can limit the heat-conducting sleeve 111 sleeved on the rotating shaft 112 from moving axially along the rotating shaft 112. When the heat-conducting sleeve 111 needs to be replaced, the heat-conducting sleeve 111 can be taken out axially along the rotating shaft 112 and replaced with another heat-conducting sleeve 111 after the end portion 21 clipped together with the body 11 is removed, so that the hair curling device can realize different curling effects by using different heat-conducting sleeves 111 and winding hair around the heat-conducting sleeve 111. At the same time, the body 11 and the end portion 21 clipped together enable the hair curling device to replace the heat-conducting sleeve 111 more quickly and conveniently.

[0046] For details, please refer to Figure 5 and Figure 6 The outer end surface of the first fastener 113 close to the second fastener 211 is recessed in a direction away from the second fastener 211 to form a first groove 1133, and a second groove 1132 connected to the first groove 1133 is provided in the first fastener 113, and the second groove 1132 is arranged at an angle to the first groove 1133;

[0047] A first protrusion 2113 is provided at one end of the second fastener 211 close to the first fastener 113. When the end head 21 is installed, the first protrusion 2113 is placed in the first groove 1133 and after the second fastener 211 is rotated, the first protrusion 2113 at least partially enters the second groove 1132, and the second groove 1132 limits the axial movement of the first protrusion 2113 along the rotating shaft 112.

[0048] Align the first protrusion 2113 on the second clip 211 with the opening of the first groove 1133 on the first clip 113, move the first protrusion 2113 to insert it into the bottom of the first groove 1133, rotate the second clip 211 so that the first protrusion 2113 rotates from the first groove 1133 to the second groove 1132, and the first protrusion 2113 partially deforms to abut against the second groove 1132, and the first protrusion 2113 and the second groove 1132 are interference-fitted. The first protrusion 2113 cooperates with the first groove 1133 and the second groove 1132 to realize the snap connection between the end portion 21 and the body 11, and the first groove 1133 plays a positioning and guiding role for the first protrusion 2113, so that the first clip 113 and the second clip 211 can be snapped together quickly and accurately.

[0049] Specifically, when the end portion is installed, after the first protrusion is placed in the first groove, the second clip rotates at an angle less than 180 degrees, and after the rotation, the first protrusion at least partially enters the second groove, and the second groove limits the axial movement of the first protrusion along the rotating shaft. The utility model only needs to rotate a small angle to complete the clip connection between the end portion and the body, making the disassembly and assembly of the hair curling device very convenient.

[0050] For further information, see Figure 5 , a plurality of first protrusions 2113 , first grooves 1133 , and second grooves 1132 may be provided.

[0051] In this embodiment, four groups of matching first protrusions 2113, first grooves 1133 and second grooves 1132 are preferably arranged. The opening of the first groove 1133 is arranged on the outer end face of the first latch 113. The four first grooves 1133 are arranged around the center of the first latch 113. The second groove 1132 is arranged at an end away from the opening of the first groove 1133 and connected to the first groove 1133. The first protrusion 2113 inserted into the first groove 1133 can be rotated 45 degrees and then completely enter the second groove 1132, so that the first latch 113 and the second latch 211 are more firmly connected when being snapped.

[0052] For details, please refer to Figure 5 and Figure 6 A side of the second groove 1132 close to the outer end face of the first latch 113 is set as a closed end face 1134, and the closed end face 1134 and the first protrusion 2113 cooperate with the end face of one side of the closed end face 1134 to respectively set one of the second protrusion 1135 and the third groove 2112. When the first protrusion 2113 at least partially enters the second groove 1132, the second protrusion 1135 can be snapped into the third groove 2112.

[0053] By providing the second protrusion 1135 and the third groove 2112, the user can feel whether the first fastener 113 and the second fastener 211 are snapped into place by hand during use, and the user can get hand feedback when the first protrusion 2113 enters and leaves the second groove 1132. After the second protrusion 1135 is snapped into the third groove 2112, the first fastener 113 and the second fastener 211 can be prevented from loosening during use after being snap-connected.

[0054] Specifically, the closed end face 1134 of the second groove 1132 is set at an angle to the outer end face of the first locking member 113, and the first protrusion 2113 is set to cooperate with one side end face of the closed end face 1134 and parallel to the closed end face 1134. When the first protrusion 2113 is at least partially placed in the second groove 1132, the first protrusion 2113 presses against the second groove 1132.

[0055] By setting the second groove 1132 and the end face of the first protrusion 2113 at the same angle, the process of the first protrusion 2113 entering the second groove 1132 is smoother, and the second protrusion 1135 is more easily engaged in the third groove 2112 during this process, thereby improving the user experience of the first buckle 113 and the second buckle 211 in the buckle connection process.

[0056] Furthermore, the closed end face 1134 is inclined gradually away from the outer end face of the first fastener 113 from the end close to the first groove 1133. The angle between the closed end face 1134 and the outer end face of the first fastener 113 is less than 90 degrees, and is set to 45 degrees in this example. The inclined closed end face 1134 allows the first fastener 113 and the second fastener 211 to deflect when they are fastened together, thereby preventing them from falling off after the fastening connection.

[0057] Optionally, the angle between the closed end surface 1134 and the outer end surface of the first locking member 113 can also be set to 15 degrees, 25 degrees, 35 degrees, 55 degrees, etc.

[0058] Specifically, see Figure 3 A storage space is provided in the rotating shaft 112, and a heating element 114 is provided in the storage space; the first fastener 113 is placed in the heat-conducting sleeve 111 and at least partially accommodated in the storage space of the rotating shaft 112, and the first fastener 113 and the rotating shaft 112 are detachably connected. This arrangement can make full use of the space in the heat-conducting sleeve 111 and the rotating shaft 112, so that the body 11 of the curling device is smaller in size and more convenient to carry and store.

[0059] Specifically, the inner wall 1112 of the heat-conducting sleeve 111 is provided with ribs 1115 or foolproof grooves 1121, and the outer wall 1111 of the rotating shaft 112 is provided with foolproof grooves 1121 or ribs 1115 adapted to the ribs 1115 or foolproof grooves 1121. The cooperation between the ribs 1115 and the foolproof grooves 1121 enables the rotating shaft 112 to drive the heat-conducting sleeve 111 to rotate and facilitates the removal and assembly of the heat-conducting sleeve 111 from the rotating shaft 112.

[0060] Furthermore, two ribs 1115 are provided on the inner wall 1112 of the heat-conducting sleeve 111, and two fool-proof grooves 1121 are correspondingly provided on the outer wall 1111 of the rotating shaft 112. The ribs 1115 can be snapped into the fool-proof grooves 1121, so that the heat-conducting sleeve 111 is sleeved on the rotating shaft 112 and rotates with the rotating shaft 112.

[0061] For details, please refer to Figure 2 and Figure 6The part of the first locking member 113 accommodated in the rotating shaft 112 is provided with a first through hole 1136 that penetrates the first locking member 113 and avoids the first groove 1133 and the second groove 1132. The side wall of the rotating shaft 112 is provided with a connecting hole 1116 corresponding to the first through hole 1136. The first locking member 113 and the rotating shaft 112 are threadedly connected by the first threaded member 115 passing through the first through hole 1136 and the connecting hole 1116.

[0062] The first clip 113 and the rotating shaft 112 are connected together so that the end portion 21 clipped to the first clip 113 can rotate synchronously with the heat-conducting sleeve 111, thereby avoiding wear at the abutment point between the end portion 21 and the heat-conducting sleeve 111.

[0063] For details, please refer to Figure 2 and Figure 4 The end portion 21 also includes an end cover 212, a second through hole 2121 penetrating the end cover 212 is provided in the middle of the end cover 212, a third through hole 2111 penetrating the second fastener 211 is provided in the middle of the second fastener 211, and the end cover 212 and the second fastener 211 are threadedly connected through the second threaded member 215 passing through the second through hole 2121 and the third through hole 2111.

[0064] The end portion 21 is composed of a detachably connected end cover 212 and a second fastener 211, so that the end portion 21 can be separately disassembled and the second fastener 211 can be replaced, thereby increasing the service life of the hair curling device.

[0065] Specifically, see Figure 2 The first latch 113 is provided with a third protrusion 1131 corresponding to the third through hole 2111 of the second latch 211. When the first protrusion 2113 is placed in the first groove 1133 and / or the second groove 1132, the third through hole 2111 can be sleeved on the third protrusion 1131.

[0066] By providing the third protrusion 1131 and the third through hole 2111 on the first latch 113 and the second latch 211, the cooperation between the third protrusion 1131 and the third through hole 2111 can avoid the first latch 113 and the second latch 211 from being misaligned in the snap connection, thereby improving the stability of the snap connection.

[0067] For details, please refer to Figure 2 and Figure 4A hollow connecting piece 2114 is arranged in the third through hole 2111 of the second fastener 211.
