[0047] 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 irons usually use threaded parts to achieve detachable connection. The threaded connection method requires users to spend a long time to disassemble. At the same time, the thread is prone to slippage during long-term and improper use, which makes it inconvenient to disassemble the curling iron and the connection is unstable.

[0048] Please refer to Figure 1 and Figure 2In 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 assembly 1, 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, and the heat-conducting sleeve 111 and the rotating shaft 112 are detachably connected.

[0049] A first locking component 113 is disposed on one end of the rotating shaft 112 close to the opening, and a second locking component 211 is disposed on the end portion 21 corresponding to the first locking component 113 .

[0050] 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 .

[0051] The first buckle 113 and the second buckle 211 are buckled together to realize a detachable connection between the end portion 21 and the body 11. After the buckle 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 buckled together with the body 11 is disassembled, so that the hair curling assembly 1 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 buckle connection between the body 11 and the end portion 21 enables the hair curling assembly 1 to replace the heat-conducting sleeve 111 more quickly and conveniently.

[0052] For details, please refer to Figure 5 and Figure 6 A first clip 113 is provided at one end of the rotating shaft 112 close to the opening, and a second clip 211 is provided at the end portion 21 corresponding to the first clip 113. A first protrusion 2113 is provided at one end of the second clip 211 away from the end portion 21, a slide is provided at one end of the first clip 113 away from the rotating shaft 112, a groove 1132 connected to the slide is provided at the end of the slide, and the concave direction of the groove 1132 is opposite to that of the first slide 1133, and an elastic member 116 is provided between the first clip 113 and the second clip 211, and the elastic member 116 is preferably provided as a spring.

[0053] When connecting the end portion 21 and the body 11, the two ends of the elastic member 116 respectively abut against the first clip 113 and the second clip 211, the first protrusion 2113 is placed in the slide and the second clip 211 presses the elastic member 116, and after the second clip 211 is rotated to make the first protrusion 2113 slide along the slide, the first protrusion 2113 is pushed into the groove 1132 by the elastic member 116, the groove 1132 and the first protrusion 2113 are engaged, and the outer end surface of the end portion 21 close to the second clip 211 abuts against the heat-conducting sleeve 111.

[0054] When the first protrusion 2113 is engaged in the groove 1132, the movement of the first protrusion 2113 can be limited by the inner wall of the groove 1132. At the same time, the elastic restoring force of the elastic member 116 causes the first latch member 113 and the second latch member 211 to move in opposite directions. The first protrusion 2113 and the groove 1132 are locked with each other to make the connection between the end portion 21 and the main body 11 more stable.

[0055] Further, the slideway includes a first slideway 1133 and a second slideway 1134, the first slideway 1133 is axially arranged along the first clip 113, the second slideway 1134 is connected to the first slideway 1133 and is arranged at an angle to the first slideway 1133, and a groove 1132 is arranged on the inner surface of the second slideway 1134 away from the bottom surface of the first slideway 1133. Apply external force to align the first protrusion 2113 on the second clip 211 with the opening of the first slideway 1133 on the first clip 113, move the first protrusion 2113 to insert into the bottom of the first slideway 1133, rotate the second clip 211 so that the first protrusion 2113 slides from the first slideway 1133 along the second slideway 1134 and reaches the groove 1132, and after the external force is withdrawn, the elastic restoring force of the elastic member 116 pushes the first protrusion 2113 into the groove 1132, and the first protrusion 2113 and the groove 1132 are engaged with each other. The first slideway 1133 and the second slideway 1134 play a role in positioning and guiding the first protrusion 2113, so that the first latching member 113 and the second latching member 211 can be fast and accurately engaged.

[0056] For further information, see Figure 5 , a plurality of first protrusions 2113 , first slideways 1133 , and grooves 1132 may be provided.

[0057] In this embodiment, two sets of matching first protrusions 2113, first slides 1133 and grooves 1132 are preferably arranged. The opening of the first slide 1133 is arranged on the outer end face of the first fastener 113. The first protrusion 2113 inserted into the first slide 1133 can be rotated 180 degrees and then completely enter the groove 1132, so that the first fastener 113 and the second fastener 211 are more firmly connected when being fastened.

[0058] Specifically, see Figure 3A 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 is 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 assembly 1 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 6 The 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 slideway and the groove 1132, and 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 through the first threaded member 115 that passes 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 5 and Figure 6 The first buckle 113 has a hollow portion 1135 at one end close to the rotating shaft 112, and the hollow portion 1135 is connected to the second slideway 1134. The hollow portion 1135 can reduce the weight of the first buckle 113, making the curling assembly 1 lighter. At the same time, the hollow portion 1135 connected to the second slideway 1134 can balance the air pressure in the second slideway 1134, so that the first protrusion 2113 can slide more smoothly in the second slideway 1134.

[0064] 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.

[0065] 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 assembly 1 .

[0066] Specifically, see Figure 2 The first locking member 113 is provided with a second protrusion 1131 corresponding to the third through hole 2111 of the second locking member 211 . When the first protrusion 2113 is placed in the first slideway 1133 or the groove 1132 , the third through hole 2111 can be sleeved on the second protrusion 1131 .

[0067] By providing the second protrusion 1131 and the third through hole 2111 on the first latch 113 and the second latch 211, the cooperation between the second 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.

[0068] For details, please refer to Figure 2 and Figure 4 A hollow connecting piece 2112 is arranged in the third through hole 2111 of the second fastener 211. The connecting piece 2112 passes through the third through hole 2111 and one end is clamped on the second fastener 211. The second threaded piece 215 passes through the second through hole 2121 and is threadedly connected with the connecting piece 2112. The second fastener 211 and the end cover 212 are detachably connected through the connecting piece 2112. The detachable connecting piece 2112 and the second fastener 211 can reduce the manufacturing precision of parts and reduce the manufacturing cost.

[0069] For details, please refer to Figure 2 and Figure 4 The end portion 21 further includes a sealing member 214, which is sleeved on the end cover 212 or the second fastener 211 and placed between the end cover 212 and the second fastener 211; when the body 11 and the end portion 21 are connected by snapping, the sealing member 214 is located in the heat-conducting sleeve 111 and the side wall of the sealing member 214 abuts against the inner wall 1112 of the heat-conducting sleeve 111. The sealing member 214 can reduce the heat transfer of the heating element 114 in the curling assembly 1 toward the end portion 21, thereby preventing the user from being burned by excessively high temperature of the end portion 21 during use.

[0070] For details, please refer to Figure 2 and Figure 4 The end portion 21 further includes a decorative piece 213, which is disposed on a side of the end cover 212 away from the second fastener 211 and shields the second through hole 2121 on the end cover 212. The decorative piece 213 makes the exposed end of the end cover 212 smoother and more beautiful.

[0071] Specifically, see Figure 3 The inner wall 1112 and the outer wall 1111 of the heat-conducting sleeve 111 can be set as a hollow area 1114 or a solid. In this embodiment, a connecting plate 1113 is set between the inner wall 1112 and the outer wall 1111 of the heat-conducting sleeve 111, and the area except the connecting plate 1113 is set as the hollow area 1114. The heating element 114 in the rotating shaft 112 transfers heat to the rotating shaft 112, and the rotating shaft 112 then transfers the heat to the outer wall 1111 along the inner wall 1112 and the connecting plate 1113 of the heat-conducting sleeve 111 in sequence. The inner wall 1112 of the heat-conducting sleeve 111 is in contact with the rotating shaft 112, and hair is wrapped around the outer wall 1111 to achieve a curling effect.

[0072] When the curling assembly 1 of this embodiment needs to replace the heat-conducting sleeve 111 to achieve different curling effects, the first protrusion 2113 on the second fastener 211 rotates out of the groove 1132 and enters the first slideway 1133 when the end head 21 is rotated.

[0076] Compared with the prior art, the hair curling assembly and hair curling device provided by the utility model have the following advantages:

[0077] 1. The hair curling assembly provided by the utility model comprises a body and an end portion, wherein a first clip is arranged at one end of the body, and a second clip is arranged on the end portion corresponding to the first clip; a first protrusion is arranged at an end of the second clip away from the end portion, a slide is arranged at an end of the first clip away from the body, and a groove connected to the slide is arranged at the end of the slide; an elastic member is also arranged between the first clip and the second clip, and when the end portion and the body are connected, the first protrusion rotates into the slide under the action of an external force and the second clip presses the elastic member, and when reaching the end of the slide, the external force is withdrawn, and the first protrusion is pushed into the groove by the elastic member, and the groove and the first protrusion are engaged.

[0078] The main body includes a rotating shaft and a heat-conducting sleeve which is hollow and has an opening at one end. The heat-conducting sleeve is sleeved on the rotating shaft, and the heat-conducting sleeve and the rotating shaft are detachably connected. When the heat-conducting sleeve needs to be replaced, the heat-conducting sleeve can be taken out along the axial direction of the rotating shaft and replaced with another heat-conducting sleeve by disassembling the end head connected to the main body by snapping, so that the hair curling device can achieve different curling effects through different heat-conducting sleeves. At the same time, the body and the end head connected by snapping enable the hair curling device to replace the heat-conducting sleeve more quickly and conveniently. Furthermore, when the first protrusion is snapped into the groove, the movement of the first protrusion can be limited by the inner wall of the groove, and at the same time, the elastic restoring force of the elastic member causes the first snap member and the second snap member to move in opposite directions. The first protrusion and the groove are locked with each other to make the connection between the end head and the main body more stable.

[0079] 2. In the utility model, a storage space is provided in the rotating shaft, and a heating element is provided in the storage space; the first clip is placed in the heat-conducting sleeve and at least partially accommodated in the storage space of the rotating shaft, and the first clip and the rotating shaft are detachably connected. This arrangement can make full use of the space in the heat-conducting sleeve and the rotating shaft, so that the body of the curling device is smaller in size and more convenient to carry and store.

[0080] 3. The first clip of the utility model is provided with a first through hole that penetrates the first clip and avoids the first slideway and the groove at the part of the rotating shaft that is accommodated in the rotating shaft, and a connecting hole is provided on the side wall of the rotating shaft corresponding to the first through hole, and the first clip and the rotating shaft are threadedly connected through the first through hole and the connecting hole by a first threaded member. The first clip and the rotating shaft are connected together so that the end portion that is clipped to the first clip can rotate synchronously with the heat-conducting sleeve, thereby avoiding wear at the abutment between the end portion and the heat-conducting sleeve.

[0081] 4. The end portion of the utility model also includes an end cap, a second through hole penetrating the end cap is provided in the middle of the end cap, a third through hole penetrating the second clip is provided in the middle of the second clip, and the end cap and the second clip are threadedly connected through the second threaded member passing through the second through hole and the third through hole. The end portion is composed of the detachably connected end cap and the second clip, so that the end portion can be disassembled and replaced separately, thereby improving the service life of the curling device.

[0082] 5. The first clip of the utility model is provided with a second protrusion corresponding to the third through hole of the second clip. When the first protrusion is placed in the first slideway or groove, the third through hole can be sleeved on the second protrusion. By providing the second protrusion and the third through hole on the first clip and the second clip, the cooperation between the second protrusion and the third through hole can avoid the misalignment of the first clip and the second clip in the clip connection, thereby improving the stability of the clip connection.

[0083] 6. The end portion of the utility model also includes a sealing member, which is sleeved on the end cover or the second fastener and placed between the end cover and the second fastener; when the body and the end portion are connected by snapping, the sealing member is located in the heat-conducting sleeve and the side wall of the sealing member abuts against the inner wall of the heat-conducting sleeve. By providing the sealing member, the heat of the heating element in the curling device can be reduced from being transferred toward the end portion, thereby preventing users from being burned by excessive temperature of the end portion during use.

[0084] 7. The first buckle of the utility model is provided with a hollow portion at one end close to the rotating shaft, and the hollow portion is connected to the slideway. The hollow portion can reduce the weight of the first buckle, making the curling assembly lighter. At the same time, the hollow portion connected to the slideway can balance the air pressure in the slideway, making the first protrusion slide more smoothly in the slideway.

[0085] 8. The utility model also provides a hair curling device, which has the same beneficial effects as the above-mentioned hair curling assembly and will not be described in detail here.
