Therefore, they should not be construed as limitations on the embodiments of this application.

[0030] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0031] This application provides a hair curler 1.

[0032] Please see Figures 1 to 8 The hair curler 1 includes a hair curling component, a handle component 11, a drive module 12, a controller 14, and a detection module 15.

[0033] The curling component has at least two openings for receiving hair. At least two can be two, three or more.

[0034] The multiple slots allow users to curl hair from different angles and directions, increasing styling flexibility. The different slots also accommodate hair of different lengths and thicknesses, making the curling iron suitable for various hairstyles and hair types.

[0035] The hair curling component is used to curl hair, and the handle component 11 can be used as a handheld end, allowing the user to hold the handle component 11 to perform the hair curling operation.

[0036] Specifically, the handle assembly 11 is located on one side of the curling assembly along the axial direction.

[0037] It should be noted that the axial direction refers to the direction of the central axis of the hair curling component. In this embodiment, the axial directions of the handle assembly 11, the hair curling component, and the hair curler 1 are in the same direction. When at least a part of the hair curling component rotates, the axial direction is the direction of the rotation axis of the hair curling component.

[0038] For example, the handle assembly 11 is generally cylindrical to facilitate user grip.

[0039] A receiving space 11a is formed within the handle assembly 11.

[0040] Specifically, the accommodating space 11a provides installation space and protection for the components of the hair curler 1, so that the electrical components of the hair curler 1 are not affected by external dust or other factors.

[0041] The drive module 12 is at least partially disposed in the receiving space 11a and connected to the curling component. The drive module 12 is used to drive at least a portion of the curling component to rotate. Here, the drive module 12 may drive the entire structure of the curling component to rotate, or it may drive a portion of the structure of the curling component to rotate while the other portion does not rotate. For example, the structure of the curling component used to form the opening groove does not rotate.

[0042] For example, the hair curler 1 may also include a heating element 13 for generating heat, through which the hair curler 1 irons the hair.

[0043] For example, a portion of the hair curling component is disposed around the outer periphery of the heating element 13, and at least a portion of the hair curling component is rotatable relative to the heating element 13. During the hair curling process, the drive module 12 applies a driving force to the hair curling component, and at least a portion of the hair curling component is wound around the hair and rotates circumferentially along the heating element 13, so that the heating element 13 irons the hair.

[0044] The detection module 15 is disposed on the hair curling assembly. The controller 14 is electrically connected to the drive module 12 and the detection module 15 respectively. The detection module 15 is configured to detect hair in the opening slot and generate a position signal. The controller 14 is used to: control the drive module 12 to drive the hair curling assembly based on the position signal obtained by the detection module 15, so that at least a part of the hair curling assembly performs at least one of the following actions: rotation, opening and closing, and rotation reset in the direction of the opening slot where the hair is detected.

[0045] Understandably, the controller 14 is located in the accommodating space 11a. The controller 14 can serve as the control structure for the curling iron 1, providing power and signal transmission to components such as the drive module 12, heating element 13, and detection module 15 of the curling iron 1, so that the drive module 12, heating element 13, and detection module 15 can operate according to a predetermined program to achieve the normal operation of the curling iron 1.

[0046] It should be noted that the detection module 15 is located on the hair curling component. There may be a connection between the detection module 15 and the hair curling component, or there may be no connection. No restriction is imposed here.

[0047] Here, the detection module 15 detects hair in the opening slots and generates a position signal. This position signal can be whether each opening slot contains hair, which opening slot contains hair, or the position of the hair curling component.

[0048] When the position signal continuously indicates that there is no hair in the opening slot, the drive module 12 can drive the curling component to close according to the position signal, that is, drive the curling machine 1 to stop running, thus achieving self-closing; when the position signal indicates that there is hair in the opening slot, the drive module 12 can drive the curling component to start according to the position signal, thus achieving self-starting.

[0049] When the position signal indicates that one of the opening slots contains hair, the drive module 12 can drive the curling component to rotate in the direction of the opening slot where the hair is detected, thereby increasing the curling efficiency.

[0050] After the curling is finished, when the position signal indicates that the position of the curling component deviates from the initial position, the drive module 12 can drive the curling component to rotate and reset according to the position signal.

[0051] The hair curler 1 provided in this application embodiment uses the position signal detected by the detection module 15 to drive the hair curling component to perform at least one of the following actions: rotating in the direction of the opening slot, opening and closing, and rotating and resetting. This achieves the adjustment of the working state of the hair curling component, enabling automated and intelligent operation, reducing the trouble of manual adjustment for users, and avoiding damage caused by incorrect operation. The hair curler 1 can achieve hair curling operation in the shortest time each time it is used, and can automatically return to a fixed safe position after use. The hair curler 1 has high safety and convenience, which helps to improve the user experience.

[0052] Understandably, the detection method of detection module 15 is not limited.

[0053] For example, the detection module 15 can detect hair in the opening slot using optical detection. For instance, an infrared or visible light sensor can be used to detect the presence of hair. When hair enters the opening slot, it blocks the light, causing a change in the light intensity received by the sensor, thereby triggering the detection module 15 to send a position signal to the drive module 12.

[0054] For example, the detection module 15 can detect hair in the opening slot using capacitive detection. For instance, hair can be used as a dielectric to change the capacitance of a capacitor to detect hair. When hair comes into contact with a specific area of ​​the curling iron 1, the capacitance of that area changes, and this change can be captured by the detection module 15, thereby triggering a corresponding action.

[0055] For example, the detection module 15 can also detect hair in the opening slot by pressure sensing. For instance, by installing a pressure sensor around the opening slot, the hair will apply a certain pressure to the sensor when it is inserted, and the sensor will detect this change and cause the curling component to react.

[0056] Of course, the detection module 15 can also detect hair in the opening slot using thermal detection. For example, hair has different thermal conductivity than air, and when hair comes into contact with the curling component, it may cause a change in local temperature. This change can be used to determine whether the hair is in place.

[0057] For example, the detection module 15 can detect the current position of the curling component using a magnetic sensor. Magnets are installed at different positions on the curling component, and when the curling component rotates to a specific position, the magnetic sensor detects the change in the magnetic field, thereby sending a reset signal.

[0058] For example, the detection module 15 can detect the current position of the curling component using a photoelectric encoder. A graduated code disk is mounted on the curling component, and the photoelectric encoder can accurately measure the rotation angle of the curling component. When the curling component is detected to have reached a preset reset position, a reset signal is sent.

[0059] For example, the detection module 15 can use the Hall effect to detect changes in the magnetic field. When the curling component is rotated to a specific position, the Hall effect sensor will detect the change in the magnetic field, thereby triggering a reset operation.

[0060] Of course, the detection module 15 can also perform detection in other ways, and no restrictions are placed here.

[0061] In some embodiments, the detection module 15 includes a first detection unit and a second detection unit. The first detection unit can rotate relative to the second detection unit under the drive of the hair curling component, and the second detection unit can generate a first position signal according to the rotation position of the first detection unit. The controller 14 is electrically connected to the second detection unit. The controller 14 can receive the first position signal and control the drive module 12 to drive the hair curling component to rotate and reset according to the first position signal.

[0062] In this embodiment, the first detection unit follows the rotation of the curling component to characterize the current rotation position of the curling component. The second detection unit generates a first position signal based on the position of the first detection unit, so that the drive module 12 can obtain the position of the curling component through the controller 14, thereby driving the curling component to rotate until the second detection unit detects that the first detection unit returns to the initial position with the curling component.

[0063] In some embodiments, the detection module 15 includes a third detection unit for detecting whether the opening slot accommodates hair, and is triggered and generates an in-situ signal when the opening slot accommodates hair. The controller 14 controls the drive module 12 to start the hair curling assembly based on the in-situ signal.

[0064] In this embodiment, when hair is placed in the opening slot, the third detection unit can determine that the opening slot is in a hair-accommodating state by sensing changes in light, etc., thereby generating an presence signal and transmitting it to the controller 14. The controller 14 controls the drive module 12 to drive the curling component to rotate according to the presence signal, so as to realize the curling operation. When no hair enters the opening slot, the third detection unit is not triggered, and at this time the controller 14 can control the curling component not to perform the curling operation.

[0065] In this embodiment, the detection module 15 not only has the function of detecting the position of the hair curling component, but also can identify whether the opening slot accommodates hair, thereby increasing the working reliability and convenience of the hair curling component.

[0066] In some embodiments, at least two opening slots include a first opening slot 17a and a second opening slot 17b, and the detection module 15 includes a fourth detection unit, which is used to identify whether the first opening slot is in a venting state or the second opening slot is in a venting state, and generate a second position signal.

[0067] The controller 14 can receive the second position signal and control the drive module 12 to drive the hair curling assembly to rotate in the direction of the opening groove where the hair is detected, according to the second position signal.

[0068] Specifically, when hair enters the first opening groove 17a or the second opening groove 17b, one of the first opening groove 17a and the second opening groove 17b is in a hair-accommodating state, while no hair enters the other. The detection module 15 generates a second position signal, and the controller 14 determines the rotation direction of the hair curling component based on the second position signal.

[0069] For example, if the first opening slot 17a is in the hair-accommodating state, the controller 14 can control the drive module 12 to drive the curling component to rotate counterclockwise; if the second opening slot 17b is in the hair-accommodating state, the controller 14 can control the drive module 12 to drive the curling component to rotate clockwise. In this way, the controller 14 can automatically adjust the rotation speed and direction of the curling component according to the second position signal to achieve a more intelligent curling effect.

[0070] In this embodiment, the detection module 15 identifies whether the first opening slot 17a or the second opening slot 17b is in the hair-accommodating state, determines the rotation direction of the hair curling component, and automatically rotates in different directions to achieve effective hair curling, reduce the difficulty of user operation, and increase hair curling efficiency.

[0071] It is understandable that the third detection unit and the fourth detection unit can be the same detection unit, two detection units with the same detection principle, or detection units with different detection principles.

[0072] For example, in some embodiments, the third detection unit includes a photoelectric sensor.

[0073] In some embodiments, the fourth detection unit includes a photoelectric sensor 153. The hair curling assembly includes a housing 17 and a hair curling structure 10. The hair curling structure 10 and the detection module 15 are disposed within the housing 17, and an opening slot is formed in the housing 17. The detection module 15 includes an annular circuit board 151, which is disposed on the outer periphery of the hair curling structure 10 and spaced circumferentially from the hair curling structure 10. The annular circuit board 151 is electrically connected to the controller 14, and the photoelectric sensor 153 is disposed at one end of the annular circuit board 151 axially away from the handle assembly 11.

[0074] Specifically, the photoelectric sensor 153 can effectively detect the presence of small objects. When an object blocks the light, the photoelectric sensor 153 cannot receive sufficient light intensity, thus determining that an object has entered. Therefore, when hair enters the first opening slot 17a or the second opening slot 17b, the light from either opening slot 17a or the second opening slot 17b is blocked. The photoelectric sensor 153 can then determine that hair has entered the first opening slot 17a or the second opening slot 17b, and generate a second position signal, which is transmitted to the controller 14. This, in turn, controls the drive module 12 to drive the hair curling structure 10 to begin curling.

[0075] For example, the number of photoelectric sensors 153 can be two, one corresponding to the first opening slot 17a and the other corresponding to the second opening slot 17b, so as to identify the capacitive state of the first opening slot 17a and the second opening slot 17b respectively.

[0076] In some embodiments, the first detection unit includes a magnetic element 16, and the second detection unit includes a Hall element 152. The Hall element 152 is disposed at one end of the annular circuit board 151 away from the handle assembly 11 along the axial direction. The magnetic element 16 can rotate relative to the Hall element 152 and the annular circuit board 151 under the drive of the curling structure 10. The Hall element 152 is used to magnetically sense the magnetic element 16 to generate a first position signal.

[0077] The first and second detection units can detect the position of the hair curling components based on the Hall effect. The Hall effect refers to the voltage difference generated in the direction perpendicular to both the current and the magnetic field when an electric current flows through a conductor placed in a magnetic field.

[0078] For example, the second detection unit may include a Hall element 152, a signal amplification circuit, a regulated power supply, and an output interface. The Hall element 152 is capable of responding to a magnetic field and generating a Hall voltage. The signal amplification circuit amplifies the signal to a level that can be recognized by the controller 14. The regulated power supply ensures the normal operation of the Hall element 152 and the amplification circuit. The output interface is used to output the processed electrical signal to the controller 14.

[0079] The magnetic component 16 is a magnetic object. Exemplarily, the magnetic component 16 can be made of a permanent magnet material. Exemplarily, the magnetic component 16 is a magnet, which has a simple structure and is easy to install.

[0080] It should be noted that at least a portion of the magnetic component 16 is disposed in the hair curling structure 10. The magnetic component 16 may be disposed within the space defined by the hair curling structure 10 and connected to the hair curling structure 10. This connection may be a snap-fit ​​or the like, as long as it allows the magnetic component 16 to rotate with the hair curling structure 10. Alternatively, the magnetic component 16 may be disposed within the space defined by the hair curling structure 10 and other structures, which is not limited here.

[0081] The magnetic element 16 is used to magnetically sense the Hall element 152. The magnetic element 16 is disposed on the curling structure 10 and can rotate with the curling structure 10. The Hall element 152 and the ring circuit board 151 remain stationary relative to the magnetic element 16 and the curling structure 10. That is, the Hall element 152 and the ring circuit board 151 are in a fixed position relative to the magnetic element 16 and the curling structure 10. Thus, when the curling structure 10 drives the magnetic element 16 to rotate, the position of the magnetic element 16 relative to the Hall element 152 changes. The Hall element 152 detects the change in the magnetic field and generates a corresponding electrical signal, namely the first position signal, to reflect the current position of the curling structure 10.

[0082] After receiving the first position signal, the controller 14 sends a command to the drive module 12 according to the first position signal, so that the drive module 12 drives the hair curling structure 10 to rotate until it returns to the initial position.

[0083] It should be noted that the initial position can be a fixed, safe position that the pre-set curling structure 10 is in before it is driven.

[0084] Understandably, after receiving the first position signal, the controller 14 can compare the first position signal with the initial position to determine whether the curling component needs to be reset. When a reset is required, the control drive module 12 is started. During this process, the Hall element 152 can continuously detect the position of the curling component based on the position change of the magnetic component 16 and feed it back to the controller 14. The controller 14 thus determines that the curling component is accurately reset.

[0085] It is understood that in this embodiment, the Hall element 152 is disposed on the outer periphery of the curling structure 10, and the magnetic element 16 is disposed on the curling structure 10. Thus, the Hall element 152 and the magnetic element 16 are located close to each other, so that the magnetic element 16 is within the detection range of the Hall element 152 when it rotates.

[0086] For example, at least a portion of the magnetic element 16 is located within the circumference of the annular circuit board 151. This allows the magnetic element 16 to be closer to the Hall element 152, providing a stronger magnetic field signal and improving the detection accuracy of the Hall element 152. This enables the Hall element 152 to accurately sense changes in the position of the magnetic element 16, helping to more accurately determine the current position of the curling assembly. Furthermore, the interference from external magnetic fields is minimized, improving the anti-interference capability of the detection module 15.

[0087] In this embodiment, the close-range magnetic component 16 and Hall element 152 work together to make the magnetic field signal stronger and more stable, enabling faster signal transmission and processing, improving the system's response speed, and increasing detection efficiency and accuracy.

[0088] The method by which the annular circuit board 151 and Hall element 152 are stationary relative to the curling structure 10 and the magnetic component 16 is not limited. The annular circuit board 151 and Hall element 152 can be arranged circumferentially spaced from the curling structure 10, that is, they do not contact the curling structure 10. In this way, they can be stationary and do not interfere with the curling structure 10. Of course, the annular circuit board 151 and Hall element 152 can also be in contact with the curling structure 10, and stationary can be achieved through other components. There is no limitation here.

[0089] The specific shape of the magnetic component 16 is not limited; it can be cylindrical, square, ring-shaped, or strip-shaped, etc. There are no restrictions here.

[0090] It is understandable that when the curling structure 10 rotates, the outer shell 17 does not rotate; that is, the curling structure 10 rotates relative to the outer shell 17. When the hair enters the opening slot of the outer shell 17, the curling structure 10 rotates, thus causing the hair to rotate in the desired direction.

[0091] For example, the housing 17 and the handle assembly 11 abut against each other along the axial direction. This can be achieved by one end face of the housing 17 along the axial direction contacting one end face of the handle assembly 11 along the axial direction, in which case there is no connection between the housing 17 and the handle assembly 11. Alternatively, the one end face of the housing 17 along the axial direction can be engaged with the handle assembly 11, in which case there is a connection between the housing 17 and the handle assembly 11.

[0092] For example, when hair is placed into the opening slot, the third detection unit detects that the hair is in place, the curling assembly is activated, and the photoelectric sensor 153 identifies which opening slot the hair is in, thereby driving the curling structure 10 to rotate towards the opening slot where the hair is placed to achieve curling. After the curling structure 10 has finished curling, the hair is removed, the third detection unit detects that there is no hair in the opening slot, the Hall element 152 and the magnetic component 16 are magnetically sensed, the position of the magnetic component 16 is identified, and the current position of the curling structure 10 is determined, and a first position signal is generated. The controller 14 determines whether a reset operation is required based on the first position signal. If a reset is required, the controller 14 controls the drive module 12 to drive the curling structure 10 to rotate. During this process, the Hall element 152 continuously detects the position of the magnetic component 16 and sends it to the controller 14 until the Hall element 152 detects that the position of the magnetic component 16 is in the initial position, thereby determining that the curling structure 10 has returned to the initial position. Then, based on the information that the hair is not in place detected by the third detection unit, the curling assembly is closed, and the curler 1 stops working.

[0093] The ring circuit board 151 can integrate Hall element 152, photoelectric sensor 153 and other components, so that the detection module 15 can simultaneously detect the position of the hair curling component and identify the position of the hair. The detection module 15 has a simple structure and increases the operational flexibility of the hair curler 1.

[0094] In some embodiments, please refer to Figure 5 and Figure 6 The detection module 15 also includes a connector 154, which is disposed on the side of the annular circuit board 151 facing the handle assembly 11 along the axial direction; the curling iron 1 includes a cable that connects the connector 154 and the controller 14.

[0095] In other words, in this embodiment, the ring circuit board 151 is connected to the controller 14 via connector 154 to transmit the first position signal and the second position signal to the controller 14, thereby achieving real-time signal transmission. The position of connector 154 facilitates wiring connection with the controller 14 and does not interfere with the curling assembly, increasing structural reliability.

[0096] In some embodiments, please refer to Figure 2 and Figure 3The drive module 12 includes a drive member 121 and a transmission member 122. At least a portion of the drive member 121 is disposed within the receiving space 11a. The power output shaft of the drive member 121 is connected to the hair curling structure 10 through the transmission member 122 to drive the hair curling structure 10 to rotate relative to the outer shell 17. The hair curling structure 10 surrounds the outer periphery of the transmission member 122. The magnetic member 16 is disposed between the hair curling structure 10 and the transmission member 122.

[0097] The drive element 121 is used to provide power. The specific construction of the drive element 121 is not limited; for example, the drive element 121 may be an electric motor.

[0098] The transmission member 122 is used to connect the power output shaft of the drive member 121 and the curling structure 10 to transmit power. The transmission member 122 can be a gear, belt, etc., and exemplarily, the transmission member 122 is a gear.

[0099] In this embodiment, the magnetic component 16 is disposed between the hair curling structure 10 and the transmission component 122. On the one hand, this facilitates the synchronous rotation of the magnetic component 16 and the hair curling structure 10, and the relative position of the magnetic component 16 and the hair curling structure 10 can be relatively fixed, thereby making it easy to reflect the current position of the hair curling structure 10 based on the position of the magnetic component 16. On the other hand, it also protects the magnetic component 16, reducing the probability of damage to the magnetic component 16, facilitating the magnetic induction between the magnetic component 16 and the Hall element 152, and at the same time, reducing the risk of the magnetic component 16 falling off, thus improving installation stability.

[0100] In some embodiments, please refer to Figure 7 and Figure 8 The outer wall of the transmission component 122 is provided with a first mounting groove 122a, and the inner wall of the hair curling structure 10 is provided with a second mounting groove 10a. The first mounting groove 122a faces the second mounting groove 10a, and the first mounting groove 122a and the second mounting groove 10a together define the mounting space. The magnetic component 16 is disposed in the mounting space.

[0101] In other words, the opening of the first mounting groove 122a faces the second mounting groove 10a, and the opening of the second mounting groove 10a faces the first mounting groove 122a. The first mounting groove 122a and the second mounting groove 10a together enclose the mounting space. The mounting space can provide a space for the magnetic component 16 while constraining the magnetic component 16 so that the relative position of the magnetic component 16 and the hair curling structure 10 is fixed. At the same time, when the hair curler 1 moves or vibrates slightly during operation, the mounting space can also keep the magnetic component 16 stable.

[0102] The shapes of the first mounting groove 122a and the second mounting groove 10a are not limited, as long as the mounting space they enclose allows the magnetic component 16 to be installed stably.

[0103] In some embodiments, please refer to Figure 7 and Figure 8 The outer wall of the transmission component 122 also has at least one protrusion 1221, and the magnetic component 16 abuts against the protrusion 1221 on the side facing the handle assembly 11.

[0104] In this embodiment, the protrusion 1221 can provide support for the magnetic component 16. Specifically, the magnetic component 16 abuts against the protrusion 1221 and is partially disposed in the first mounting groove 122a. When the transmission component 122 docks with the hair curling structure 10, the protrusion 1221 can also facilitate the insertion of the magnetic component 16 into the second mounting groove 10a. Furthermore, the setting of the protrusion 1221 can further reduce the probability of the magnetic component 16 coming out, thereby achieving stable installation of the magnetic component 16.

[0105] In some embodiments, please refer to Figure 7 and Figure 8 The curly structure 10 has a relief opening 10b, and the protrusion 1221 is inserted into the relief opening 10b.

[0106] In other words, the protrusion 1221 has a sufficient area so that the side surface of the magnetic component 16 facing the handle assembly 11 along the axial direction can completely abut against the protrusion 1221. While providing sufficient stable support for the magnetic component 16, it can also be positioned with the hair curling structure 10, which facilitates the installation of the hair curling structure 10 and the transmission component 122.

[0107] The number of protrusions 1221 can be one, two, or more. For example, the number of protrusions 1221 is four.

[0108] The number of clearance openings 10b can be one, two, or more. For example, the number of clearance openings 10b is four.

[0109] The number of clearance openings 10b corresponds one-to-one with the number of protrusions 1221.

[0110] In some embodiments, one of the transmission member 122 and the curling structure 10 is provided with at least one slot 10c, and the other is provided with at least one block 1222, which is inserted into the slot 10c to achieve the connection between the transmission member 122 and the curling structure 10.

[0111] Specifically, the cooperation between the locking block 1222 and the slot 10c enables the transmission component 122 to dock with the hair curling structure 10, thereby connecting the transmission component 122 and the hair curling structure 10. When it is necessary to disconnect the transmission component 122 and the hair curling structure 10, simply remove the locking block 1222 from the slot 10c. This is simple and convenient, increasing the ease of assembly between the transmission component 122 and the hair curling structure 10.

[0112] In some embodiments, please refer to Figure 7 and Figure 8 The slot 10c is provided on the hair curling structure 10, and the block 1222 is provided on the transmission member 122. The block 1222 is provided with a guide slope 1222a, which extends axially toward the handle assembly 11. The guide slope 1222a extends obliquely toward the hair curling structure 10 to guide the docking of the block 1222 and the slot 10c.

[0113] Specifically, the guide slope 1222a serves a guiding function. When the locking block 1222 contacts the locking slot 10c, the guide slope 1222a guides the locking block 1222 to slide into the locking slot 10c along the correct path, thus confining the locking block 1222 within the locking slot 10c, reducing the probability of the locking block 1222 dislodging from the locking slot 10c, and increasing the docking stability between the locking block 1222 and the locking slot 10c. Furthermore, the guide slope 1222a also serves a foolproof function, ensuring correct docking between the transmission component 122 and the hair curling structure 10. Simultaneously, the inclined design of the guide slope 1222a also reduces frictional wear generated during the contact process between the locking block 1222 and the locking slot 10c.

[0114] The number of card blocks 1222 and card slots 10c is unlimited; there can be one, two, or more. Each card block 1222 corresponds to one card slot 10c. For example, there are four card blocks 1222 and four card slots 10c.

[0115] In some embodiments, please refer to Figure 3 , Figure 7 and Figure 8 The hair curling structure 10 includes a hair curling component 101 and a mounting base 102. The hair curling component 101 is connected to the end of the mounting base 102 away from the handle assembly 11. The mounting base 102 forms a hollow space 102a. The transmission component 122 passes through the hollow space 102a and is spaced apart from the end of the mounting base 102 that is close to the hair curling component 101 along the axial direction. The hair curler 1 includes a bearing 18, which is disposed within the axial distance between the transmission component 122 and the mounting base 102.

[0116] Specifically, the annular circuit board 151 is disposed on the outer periphery of the mounting base 102 and is spaced circumferentially from the mounting base 102. A clearance opening 10b and a slot 10c are disposed on the mounting base 102.

[0117] The curling element 101 is used to curl hair, and the mounting base 102 is used to dock with the transmission element 122 to connect the curling structure 10 and the transmission assembly. The transmission element 122 passes through the hollow space 102a, which can make full use of the internal space of the mounting base 102, making the overall design of the curling iron 1 more compact and reducing the size of the device. It also facilitates the transmission between the transmission element 122 and the mounting base 102, reducing resistance during transmission and making the movement of the transmission element 122 within the hollow space 102a more stable. Simultaneously, it also facilitates the disassembly and assembly of the curling structure 10 and the transmission element 122.

[0118] The bearing 18 can reduce the friction between the transmission component 122 and the mounting base 102 through rolling or sliding contact, thereby improving transmission efficiency and reducing wear rate.

[0119] In some embodiments, please refer to Figure 3 and Figure 7 The magnetic element 16 is located on the outer circumferential side of the bearing 18 and is spaced apart from the bearing 18 circumferentially. The magnetic element 16 and the bearing 18 can generate magnetic force to limit the bearing 18 radially.

[0120] Specifically, the corresponding arrangement of the magnet and the bearing 18 can radially limit the bearing 18, reduce the radial movement of the bearing 18 during rotation, and maintain the installation stability and movement stability of the bearing 18.

[0121] In addition, the magnetic force between the magnetic component 16 and the bearing 18 can provide a levitation effect, limiting the bearing 18 when the magnetic component 16 is not in contact with the bearing 18, reducing the friction between the magnetic component 16 and the bearing 18, and increasing the stability of the hair curler 1's movement.

[0122] In some embodiments, please refer to Figures 5 to 8 The hair curler 1 includes a connector 19, a portion of which passes through the inner periphery of the transmission member 122. The connector 19 has at least one support structure 191. The outer wall of the connector 19 extends outward and toward the annular circuit board 151 to form the support structure 191. The annular circuit board 151 is supported on the support structure 191.

[0123] In this embodiment, the connector 19 can provide installation support for the transmission component 122 and also provide connection space for the connection between the transmission component 122 and the drive component 121. Furthermore, the support structure 191 of the connector 19 can support the annular circuit board 151, increase the installation stability of the annular circuit board 151, and improve the working reliability.

[0124] In some embodiments, please refer to Figures 5 to 8A portion of the support structure 191 protrudes toward the side away from the handle assembly 11 to form a positioning protrusion 192. The annular circuit board 151 has a positioning hole 151a, and the positioning protrusion 192 passes through the positioning hole 151a.

[0125] In this embodiment, the cooperation between the positioning protrusion 192 and the positioning hole 151a facilitates the precise positioning between the connector 19 and the annular circuit board 151, reducing installation deviation. Furthermore, the positioning protrusion 192 passing through the positioning hole 151a can also restrict the movement of the annular circuit board 151, making assembly fast and accurate while increasing connection stability.

[0126] In some embodiments, please refer to Figure 5 and Figure 6 The hair curler 1 also includes an annular baffle 20, which is disposed on the side of the annular circuit board 151 away from the handle assembly 11 along the axial direction. The annular baffle 20 is disposed on the outer periphery of the hair curling structure 10 and is spaced apart from the hair curling structure 10 along the circumferential direction.

[0127] In a plane projection perpendicular to the axis of the curling iron 1, the projection of the annular circuit board 151 does not exceed the area where the baffle is located.

[0128] Specifically, the annular baffle 20 can protect the annular circuit board 151, reduce the impact of dust and other substances on the annular circuit board 151, and increase the operational reliability of the annular circuit board 151.

[0129] The method of fixing the annular baffle 20 is not limited. For example, the positioning protrusion 192 of the connector 19 passes through the annular circuit board 151 and the annular baffle 20, so that the positioning protrusion 192 can simultaneously achieve the installation and positioning of the annular circuit board 151 and the annular baffle 20.

[0130] In some embodiments, the annular baffle 20 is a light-transmitting element.

[0131] In other words, the annular baffle 20 allows light to pass through, refract, or reflect light, so that the photoelectric sensor 153 of the detection module 15 can sense changes in light and thus identify the emission state.

[0132] In this embodiment, the annular baffle 20 not only serves as a dustproof barrier but also allows light to pass through, further increasing the working reliability of the curling iron 1.

[0133] The method of forming the annular baffle 20 is not limited.

[0134] In some embodiments, the annular baffle 20 is a one-piece component.

[0135] In other words, the annular baffle 20 is manufactured as a single piece, which allows for rapid production and installation, and facilitates increased assembly efficiency.

[0136] In other embodiments, the annular baffle 20 includes two separately arranged baffles that are joined together along a first direction and surround the outer periphery of the hair curling structure 10, wherein the first direction is perpendicular to the axial direction of the hair curler 1.

[0137] In this embodiment, the annular baffle 20 is a split structure, which facilitates docking along the first direction after the curling structure 10 is installed, increasing docking convenience. When it is necessary to remove the annular baffle 20, the connection between the two baffles can be released.
