[0041] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0042] See also Figure 1-10 In an embodiment of the present invention, an automatic hair curler with a replaceable hair curler connector 2 includes a hair curler body 1 and a hair curler connector 2 detachably connected to the hair curler body 1;

[0043] The curling iron body 1 is rotatably connected to a connecting seat 3 at one end corresponding to the curling iron connector 2. The curling iron connector 2 is fixedly provided with a fixing seat 4 at one end corresponding to the curling iron body 1. A slot 5 is provided along the surface of the fixing seat 4 and is connected to the connecting seat 3. The connecting seat 3 includes a connecting seat body 6 and a connected plug 7. The fixing seat 4 is provided with a connecting structure that cooperates with the plug 7 at the slot 5.

[0044] The curling iron body 1 has a built-in control assembly 8, the connector 7 is dynamically connected to the output shaft of the control assembly 8, and when the connector 7 is engaged with the slot 5, the curling iron body 1 and the curling rod connector 2 are electrically connected.

[0045] In the technical solution of the present utility model, the curling iron is divided into two main modules: a curling iron body 1 and a curling rod connector 2. The curling iron body 1 is rotatably connected to a connecting seat 3 at one end corresponding to the curling rod connector 2. A fixing seat 4 is fixedly provided at one end corresponding to the curling iron body 1 in combination with the curling rod connector 2. Thus, a connecting mechanism is formed by the connecting seat 3 and the fixing seat 4, thereby realizing a detachable connection between the curling iron body 1 and the curling rod connector 2. The detachable connection allows the two to be combined and separated. This design allows users to replace different types of curling rod connectors 2 according to different needs to meet diverse curling styling requirements. At the same time, when the curling rod connector 2 is damaged or aged, users only need to replace the curling rod connector 2 without having to repair or replace the entire curling iron, which greatly reduces maintenance costs.

[0046] When the cam 3 is in the closed position, the cam 3 is in the closed position, and the cam 3 is in the closed position, so that the cam 3 is in the closed position and the cam 3 is in the closed position, so that the cam 3 is in the closed position and the cam 3 is in the closed position.

[0047] Furthermore, in the technical field of curling irons, the control assembly 8 can be understood as a PCB board 16 and an electrically connected motor 17. The motor shaft 18 (output shaft) of the motor 17 is dynamically connected to the connector 7 and / or the connector body 6, thereby realizing the automatic curling function of the curling iron. When the motor 17 is started, the output shaft rotates, driving the connector 3 and the connector 7 to rotate, thereby rotating the curling iron connector 2, achieving automatic curling.

[0048] In the embodiment of the present utility model, the connecting structure includes an elastic snap-in member 9, which has an elastic button 10 located on the outside of the fixing seat 4 and a snap-in protrusion 11 located on the inside of the slot 5 and connected to the elastic button 10, and a snap-in groove 12 is provided on the plug-in member 7 to cooperate with the snap-in protrusion 11.

[0049] An elastic snap-fitting member 9 is provided at the slot 5 of the fixing base 4. The snap-fitting member comprises an elastic button 10 located on the outside of the fixing base 4 and a snap-fitting protrusion 11 located on the inside of the slot 5 and connected to the elastic button 10. When the plug-in connector 7 is inserted into the slot 5, the snap-fitting protrusion 11 engages with a snap-fitting slot 12 on the plug-in connector 7, thereby achieving a secure connection between the curling iron body 1 and the curling iron connector 2. The design of the elastic button 10 allows the user to release the snap-fitting protrusion 11 from the snap-fitting slot 12 by pressing the elastic button 10, thereby conveniently removing the curling iron connector 2.

[0050] The elastic snap-fit ​​connection structure cooperates with the rotating connection seat 3 and the slot 5 to form a stable and detachable connection system. During use, the rotating connection provides flexibility, the slot 5 provides an accurate docking position for the connector 7, and the elastic snap-fit ​​connection structure ensures the firmness and detachability of the connection.

[0051] The connecting structure further comprises a guide protruding rib 13, and a guide groove 14 is formed in the plug-in part 7 and is in sliding cooperation with the guide protruding rib 13.

[0052] The guide protruding rib 13 is located inside the insertion slot 5 and is opposite to the clamping protruding block 11.

[0053] The guide protruding rib 13 is arranged inside the insertion slot 5 of the fixing seat 4, and the guide groove 14 in sliding cooperation with the guide protruding rib 13 is formed in the plug-in part 7. When the plug-in part 7 is inserted into the insertion slot 5, the guide protruding rib 13 and the guide groove 14 interact to provide accurate guidance for the insertion of the plug-in part 7. This design ensures that the plug-in part 7 can be inserted into the insertion slot 5 along the correct direction and accurately cooperate with the clamping protruding block 11 to realize stable connection.

[0054] The guide protruding rib 13 is arranged opposite to the clamping protruding block 11 in the elastic clamping part 9 and cooperates to form a connecting structure. In the connecting process, the guide protruding rib 13 first guides the plug-in part 7 to the correct position, and then the clamping protruding block 11 cooperates with the clamping groove 12 on the plug-in part 7 to realize firm connection. In the dismounting process, the guide protruding rib 13 also helps to ensure that the plug-in part 7 smoothly exits the insertion slot 5.

[0055] The cooperation of the guide protruding rib 13 and the guide groove 14 can effectively prevent the plug-in part 7 from deviating or misplacing when being inserted into the insertion slot 5, and ensure that the plug-in part 7 can accurately cooperate with the clamping protruding block 11 to realize stable electrical connection and mechanical connection. This improves the connection reliability of the product and reduces the probability of failure caused by poor connection.

[0056] In the utility model embodiment, the curling iron main body 1 is provided with a slot 15 corresponding to one end of the curling iron joint 2, the plug-in part 7 is fixedly connected to the connecting seat body 6, and the connecting seat body is rotationally connected to the slot 15.

[0057] The control assembly 8 comprises a PCB 16 and a motor 17 electrically connected to the PCB 16. The motor shaft 18 of the motor 17 is sequentially arranged through the connecting seat body 6 and the plug-in part 7 and is fixedly connected to the plug-in part 7.

[0058] The slot 15 is designed to provide a specific installation position for the connector body 6. The motor shaft 18 of the motor 17 sequentially passes through the connector body 6 and the connector 7 and is fixedly connected to the connector 7. This design allows the connector 7, the connector body 6, and the motor shaft 18 of the motor 17 to form a tightly integrated whole. When the motor 17 is started, the rotational motion of the motor shaft 18 can be directly transmitted to the connector 7. Since the connector 7 is also fixedly connected to the connector body 6, the connector body 6 is driven to rotate together. The connector body 6 is then rotationally connected to the slot 15 of the curling iron body 1, thereby realizing the entire connection structure and the rotation of the curling iron connector 2.

[0059] At the same time, this integrated design ensures that the power of the motor 17 can be directly and efficiently transmitted to the curling iron joint 2 without a complex transmission mechanism in the middle, reducing power loss, allowing the curling iron joint 2 to rotate quickly and stably, thereby improving the efficiency and effect of curling hair;

[0060] From the perspective of assembly, this design makes the connection between the various components more compact. The motor shaft 18, as the core transmission component, is directly connected to the plug-in connector 7 and the connector body 6, reducing the number of additional connectors and space occupation. This not only facilitates installation and disassembly, but also improves the overall stability and reliability of the product. In the production process, it can simplify the assembly process, improve production efficiency, and reduce production costs.

[0061] Furthermore, since the motor shaft 18 is fixedly connected to the connector 7, and the connector body 6 forms an integral part with the motor shaft 18 and the connector 7, the stability of the entire structure is greatly enhanced during operation, and it can withstand large rotational forces and external forces, thereby reducing the probability of failures caused by looseness or displacement.

[0062] This design makes the curling iron more flexible and convenient during use. The user can easily adjust the rotation speed and direction of the curling iron joint 2 by controlling the speed and direction of the motor 17 to meet different curling needs. At the same time, the compact structural design also makes the product more beautiful, compact, and easy to carry and store.

[0063] In the embodiment of the present invention, the connector 7 is provided with a conductive post (not shown) electrically connected to the PCB board 16, and the slot 5 is provided with a conductive interface (not shown) electrically connected to the conductive post.

[0064] Alternatively, the connector 7 is provided with a conductive interface electrically connected to the PCB board 16, and the slot 5 is provided with a conductive post electrically connected to the conductive post.

[0065] This design uses a combination of conductive posts and conductive interfaces to achieve electrical connection between the curling iron body 1 and the curling iron connector 2. A conductive post or conductive interface is provided on the connector 7, and a corresponding conductive interface or conductive post is provided in the slot 5. When the connector 7 is inserted into the slot 5, the conductive post and the conductive interface contact each other, forming a stable electrical connection channel.

[0066] In the embodiment of the present invention, a clamping block 19 is provided on both sides of the plug connector 7 extending toward the connection base body 6, and a clamping groove 20 is provided on the connection base body 6 to match the clamping block 19;

[0067] A thread groove 21 is provided at the end of the motor shaft 18 of the motor 17 , and a connecting port 22 that cooperates with the thread groove 21 is provided on the connector 7 .

[0068] On both sides of the plug connector 7, there are provided clamping blocks 19 extending toward the connection base body 6. At the same time, a clamping groove 20 cooperating therewith is provided on the connection base body 6. When the plug connector 7 is connected to the connection base body 6, the clamping blocks 19 are inserted into the clamping groove 20. Through the cooperation of the two, the plug connector 7 and the connection base body 6 are fixedly connected. This clamping method is simple and effective, and can ensure a firm connection while being easy and quick to assemble and disassemble.

[0069] A threaded groove 21 is provided at the end of the motor shaft 18 of the motor 17, and a connection port 22 that cooperates with the threaded groove 21 is provided on the connector 7. When the motor shaft 18 is inserted into the connection port 22 of the connector 7, the two are fixedly connected by tightening the screws at the connection port 22. This threaded connection method can provide a strong connection force, ensuring that the motor shaft 18 and the connector 7 will not loosen or separate during rotation.

[0070] In the embodiment of the present invention, a mounting seat 23 is fixedly provided on one end of the curling iron body 1 corresponding to the curling rod connector 2, and the connecting seat body 6 is rotatably matched with the mounting seat 23;

[0071] The end of the mounting seat 23 facing the connecting seat body 6 is provided with a conductive ring 24 electrically connected to the control component 8 , and the end of the connecting seat body 6 facing the mounting seat 23 is provided with a conductive terminal 25 electrically connected to the conductive ring 24 .

[0072] A conductive ring 24 electrically connected to the control assembly 8 is provided at one end of the mounting base 23 facing the connector body 6. A conductive terminal 25 electrically connected to the conductive ring 24 is provided at one end of the connector body 6 facing the mounting base 23. When the connector body 6 rotates, the conductive terminal 25 always maintains contact with the conductive ring 24, thereby establishing an electrical connection between the curling iron body 1 and the connector body 6. The design of the conductive ring 24 and the conductive terminal 25 is similar to that of a rotating electrical connection device, capable of maintaining stable current transmission during relative rotation, ensuring that the curling iron connector 2 can properly receive power and signals from the control assembly 8.

[0073] In the embodiment of the present invention, the conductive terminal 25 elastically abuts against the conductive ring 24 so that the conductive terminal 25 and the conductive ring 24 are electrically connected.

[0074] The elastic abutment between the conductive terminal 25 and the conductive ring 24 increases the contact area between the two and reduces the contact resistance, thereby achieving a stable electrical connection. Even if slight vibration or shaking occurs during the rotation of the connecting seat body 6, the elastic abutment can ensure that the conductive terminal 25 will not separate from the conductive ring 24, thereby ensuring continuous transmission of current.

[0075] In the embodiment of the present invention, the conductive terminal 25 includes a first terminal 26, a second terminal 27, and a third terminal 28. The conductive ring 24 includes a first ring 29 electrically connected to the first terminal 26, a second ring 30 electrically connected to the second terminal 27, and a third ring 31 electrically connected to the third terminal 28.

[0076] The first terminal 26 and the third terminal 28 each form a loop with the second terminal 27 .

[0077] Specifically, the first terminal 26 is a PTC positive terminal, the third terminal 28 is an NTC positive terminal, and the second terminal 27 is a PTC / NTC negative terminal.

[0078] The conductive terminals 25 are divided into a first terminal 26, a second terminal 27, and a third terminal 28. The conductive ring 24 correspondingly includes a first ring 29 electrically connected to the first terminal 26, a second ring 30 electrically connected to the second terminal 27, and a third ring 31 electrically connected to the third terminal 28. This one-to-one correspondence ensures that different terminals can establish accurate electrical connections with specific rings. The various terminals and rings cooperate with each other in structure. When the connector body 6 and the mounting base 23 rotate relative to each other, the conductive terminals 25 can always maintain contact with the corresponding conductive rings, achieving a stable electrical connection.

[0079] The first terminal 26 and the third terminal 28 each form a loop with the second terminal 27. Specifically, current can start from the first terminal 26 (PTC positive terminal), pass through the connected circuit and load, and finally return to the second terminal 27 (PTC / NTC negative terminal), forming a complete loop. Similarly, current can also start from the third terminal 28 (NTC positive terminal), pass through the corresponding circuit and return to the second terminal 27, forming another loop.

[0080] Precise temperature control of the curling iron is achieved by setting the positive terminals of the PTC (positive temperature coefficient thermistor) and the NTC (negative temperature coefficient thermistor). The PTC thermistor increases in resistance as the temperature rises, limiting the current and thus preventing overheating. The NTC thermistor decreases in resistance as the temperature rises, providing a feedback signal for adjusting temperature control.

[0081] Furthermore, the second terminal 27 serves as the negative PTC / NTC terminal, forming a loop with the two positive terminals, first terminal 26 and third terminal 28, making temperature control more accurate and stable, and avoiding damage to hair caused by excessively high or low temperatures. The multi-terminal and multi-ring design and the formation of the loop enable the curling iron to better monitor and control temperature during operation. If an abnormal temperature rise or other malfunction occurs, the temperature control loop can respond promptly, cutting off the power supply or taking other protective measures, thereby improving product safety. This design increases the stability and reliability of the electrical connection. The combination of multiple terminals and rings, as well as the formation of the loop, reduces the risk of interruption of the entire electrical connection due to a single connection point failure. Even if a terminal or ring fails, the other loops can still operate normally, ensuring the basic functionality of the curling iron.

[0082] In the embodiment of the present invention, the first circular ring 29 , the second circular ring 30 and the third circular ring 31 are concentrically arranged and spaced apart from each other.

[0083] The first ring 29, the second ring 30 and the third ring 31 are arranged concentrically, which means that their centers coincide. This design allows the rings to have a fixed relative position relationship in space, making it easier for the conductive terminals 25 to contact them accordingly. The concentric arrangement ensures that during the rotation of the connector body 6, the conductive terminals 25 can always accurately contact the corresponding rings without causing poor connection due to position deviation.

[0084] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
