[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0029] The specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction. For example, different combinations of specific technical features can form different embodiments and technical solutions. To avoid unnecessary repetition, the various possible combinations of the specific technical features in this invention will not be described separately.

[0030] In the following description, the terms "first," "second," "etc." are used merely to distinguish different objects and do not indicate that the objects have the sameness or relationship. It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to the directions under normal use, while "left" and "right" refer to the left and right directions shown in the corresponding diagrams, which may or may not be the left and right directions under normal use.

[0031] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. "A plurality of" means two or more.

[0032] like Figure 1 As shown, this embodiment of the invention provides a hair styling tool that can be used to style hair, such as straightening or curling it. The hair styling tool includes a hair styling head 10 and a handle 20. The handle 20 is connected to and supports the hair styling head 10 and is held by the user. The hair styling head 10 is used to style the hair; exemplarily, the hair styling head 10 can straighten and / or curl the hair.

[0033] Understandably, the hair styling head 10 has a heating function to iron hair, achieving straight and / or curly hair. Specifically, the hair styling head 10 can only achieve curly hair, or it can only achieve straight hair. In some possible implementations, the hair styling head 10 can also perform both curly and straightening functions. For example, the hair styling head 10 can be equipped with a curling iron composed of two openable plates, both of which can generate heat. The opposite side of the two plates is flat, and the side facing away from the two plates is curved. When the two plates are open, the user can place hair into the gap between the two plates, and then close the two plates again to clamp the hair, heating the hair and pulling it in a generally straight direction to achieve straight hair. When the two plates are closed, the user can wrap the hair around the outer curved surface of the two plates and heat the hair to achieve curly hair.

[0034] like Figure 1 and Figure 2As shown, at least two hair styling heads 10 are provided, and each hair styling head 10 is different. Specifically, the hair types created by each hair styling head 10 can be all the same or all different. For example, there are two hair styling heads 10, one for curling and one for straightening, meaning the two hair styling heads 10 create different hair types, allowing the user to achieve curls and straight hair respectively. When the hair types created by each hair styling head 10 are the same, the shaping parameters of each hair styling head 10 are different. For example, each hair styling head 10 can be set as a straightening head, but the clamping capacity of each straightening head is different. It should be noted that the clamping capacity refers to the volume of hair that can be clamped at one time. Under the same heating time and the same amount of hair thickness, the user can use the straightening head with a larger clamping capacity to straighten long hair, and use the straightening head with a smaller clamping capacity to straighten bangs or short hair. Each hair styling head 10 can also be set as a curling head, but the curling diameter of each curling head is different, allowing the user to use different curling heads to create curls of different diameters. Of course, the hair types produced by each hair styling head 10 can be partially the same and partially different. In this embodiment, the styling parameters of the hair styling heads 10 that produce the same hair type are different. For example, the hair styling head 10 is provided with two curling heads and one straightening head, and the curling diameters of the two curling heads are different.

[0035] The handle 20 and each hair styling head 10 are detachably connected. Connecting different hair styling heads 10 to the handle 20 enables different functions to meet diverse user needs. Unused hair styling heads 10 can be detached for convenient storage. The handle 20 contains a component assembly 4 (see...). Figure 3 The component group 4 is used to control the working state of each hair styling head 10. That is to say, one handle 20 can be adapted to multiple hair styling heads 10, eliminating the need to replace the entire hair styling device and reducing user costs. The hair styling device provided in this embodiment of the invention can create different hair styling effects by changing different hair styling heads 10, making the functions of a single hair styling device more diverse, without the need to replace the entire hair styling device.

[0036] The hair styling tool provided in this embodiment of the invention includes a hair styling head 10 and a handle 20. The hair styling head 10 is used for hair styling, and at least two hair styling heads 10 are provided, each different. The handle 20 is detachably connected to each hair styling head 10. A component group 4 is provided inside the handle 20, which is used to control the working state of each hair styling head 10. One handle 20 can be adapted to multiple hair styling heads 10. By installing different hair styling heads 10 onto the handle 20, different effects can be achieved in hair styling, making the single hair styling tool more versatile. There is no need to replace the entire hair styling tool, reducing the user's purchase cost by eliminating the need to buy a large number of hair styling tools. Furthermore, users can separately store the hair styling heads 10 not installed on the handle 20. Compared to the entire hair styling tool, the hair styling heads 10 are smaller in size, occupy less space, and are more convenient for users to store and carry.

[0037] In some embodiments, such as Figure 3 As shown, the hair styling head 10 is provided with a first connecting component 1, and the handle 20 is provided with a second connecting component 5. The first connecting component 1 and the second connecting component 5 are plugged into each other to connect the hair styling head 10 and the handle 20 and enable electrical connection. The user only needs to perform a plugging operation to achieve electrical connection between the hair styling head 10 and the handle 20 at the same time as assembling the hair styling head 10 and the handle 20. The design is ingenious, the structure is more concise, and it is easy for users to operate.

[0038] For example, such as Figure 3 As shown, the first connecting assembly 1 includes a first plug-in 11 and a first electrical connector 12, and the second connecting assembly 5 includes a second plug-in 51 and a second electrical connector 52. The first plug-in 11 and the second plug-in 51 are coaxially sleeved. The first electrical connector 12 and the second electrical connector 52 can be pogo pins, one of which is a male head of a pogo pin, and the other is a female head of a pogo pin. The coaxial sleeved arrangement of the first plug-in 11 and the second plug-in 51 provides a larger contact area and a longer supporting arm, resulting in higher stability of the circumferential mutual positioning of the electrical connection between the hair styling head 10 and the handle 20. This reduces the possibility of relative rotation and loosening between the hair styling head 10 and the handle 20, and also ensures higher circuit reliability.

[0039] In some embodiments, such as Figure 3 and Figure 4 As shown, the hair curler includes a body 2a, a hair curling component 3a, and a detection component 4a. The body 2a forms a hair curling cavity 21a, which provides an installation space and a space for hair to be wrapped. At least a portion of the hair curling component 3a and the detection component 4a are installed in the hair curling cavity 21a.

[0040] The hair curling component 3a generates heat and rotates relative to the main body 2a to wrap around and style the hair into curls. Specifically, the hair curling component 3a can rotate relative to the main body 2a as a whole. For example, the hair curling component 3a may include a heating rod 31a that rotates relative to the main body 2a. The heating rod 31a generates heat and has a fixed claw. The claw has multiple slots in the circumferential direction. When hair is placed in one of the slots of the claw and the heating rod 31a is driven to rotate, the hair to be processed can be wrapped around it and heated, thus creating curls.

[0041] Of course, some parts of the hair curling component 3a may also rotate relative to the main body 2a. Some of these embodiments will be illustrated as examples in the following examples. It should be noted that the embodiments of the present invention do not impose further limitations on the implementation of the hair curling component 3a, as long as the hair curling component 3a can achieve hair wrapping and perming.

[0042] like Figure 4 As shown, the main body 2a has multiple hair-receiving slots 22a spaced apart from each other, and each hair-receiving slot 22a is connected to the hair-curling cavity 21a, that is, each hair-receiving slot 22a penetrates the side wall of the main body 2a. The main body 2a may have only two hair-receiving slots 22a, or it may have more than two hair-receiving slots 22a. For example, the main body 2a may have three or four hair-receiving slots 22a. The hair to be processed can be placed in any one of the hair-receiving slots 22a. The hair styling device provides multiple positions for placing hair for the user to choose from.

[0043] The detection component 4a is installed at the bottom of the curling cavity 21a and is fixedly connected to the body 2a. It can be understood that the body 2a has an open end that can hold hair axially and a connecting end that connects to the handle 20. The bottom of the curling cavity 21a is the end opposite the open end of the two opposite ends of the curling cavity 21a, and is close to the connecting end of the body 2a. The detection component 4a is radially fitted between the curling component 3a and the body 2a within the curling cavity 21a. It should be noted that the radial direction of the curling cavity 21a is the direction of its diameter; that is, on the same radial section of the curling cavity 21a, the detection component 4a is approximately annular in shape, with the curling component 3a located inside the detection component 4a and the body 2a located outside the detection component 4a.

[0044] The detection component 4a is used to detect whether any hair-containing slot 22a contains hair, and generates an presence signal when hair is contained in any hair-containing slot 22a. The component group 4 is used to control the rotation of the hair-curling component 3a according to the presence signal. The hair styling device can identify whether hair is contained in the hair-containing slot 22a, and only winds hair when hair is contained in one hair-containing slot 22a, thereby increasing the reliability and convenience of the hair-winding operation of the hair-curling component 3a.

[0045] Specifically, when hair is placed in any hair-receiving slot 22a, the detection component 4a can determine that the hair-receiving slot 22a is in a hair-receiving state by sensing changes in light, etc., thereby generating an presence signal, which is transmitted to the component group 4. The component group 4 controls the hair-curling component 3a to rotate according to the presence signal to achieve the hair-curling operation. When no hair enters the hair-receiving slot 22a, the detection component 4a is not triggered. At this time, the component group 4 (refer to...) Figure 3 This can control the hair curling component 3a to not perform the curling operation, saving energy. When hair is placed in two or more hair receiving slots 22a, the detection component 4a will not be triggered. At this time, component group 4 (refer to...) Figure 3 The curling component 3a is still controlled to not perform curling work, which reduces the possibility of scalp being pulled and makes it safer.

[0046] In some embodiments, such as Figures 4-6 As shown, the hair curling assembly 3a includes a heating rod 31a and hair claws 32a installed within the curling cavity 21a. The heating rod 31a is fixedly installed within the curling cavity 21a and is used to generate heat for ironing the hair. The hair claws 32a are sleeved on the outside of the heating rod 31a and are rotatably disposed inside the detection assembly 4a. That is, in the same cross-sectional direction of the curling cavity 21a, the detection assembly 4a is outside the hair claws 32a, and the heating rod 31a is inside the hair claws 32a. The component assembly 4a can drive the hair claws 32a to rotate around the heating rod 31a according to an in-situ signal to achieve hair wrapping. The heating rod 31a is fixedly installed, and hair wrapping is achieved only through the movable hair claws 32a, reducing the possibility of wire tangling due to the rotation of the heating rod 31a. Therefore, the user does not need to operate the heating rod 31a to rotate and reset to avoid wire tangling, which also reduces the wiring difficulty of the heating rod 31a and further reduces the user's operating difficulty, making the hair styling head 10 more convenient to use.

[0047] It should be noted that in this embodiment, the hair styling head 10 is used as a curling head. The aforementioned "shaping parameters" can be the extension length of the heating rod 31a, the diameter of the heating rod 31a, or the size of the gap between the heating rod 31a and the body 2a. By changing the extension length of the heating rod 31a by changing the hair styling head 10, hair of different lengths can be wrapped around the heating rod 31a, thus accommodating both long and short hair; by changing the diameter of the heating rod 31a, curls of different diameters can be created; and by changing the size of the gap between the heating rod 31a and the body 2a, it can accommodate multiple users with hair of different thicknesses.

[0048] When hair is in different hair-receiving slots 22a, the curling component 3a rotates in different directions. Thus, the detection component 4a automatically identifies which specific slot in each hair-receiving area the hair to be processed is in and generates different rotation signals. Based on these different signals from the detection component 4a, the curling component 3a automatically rotates in the corresponding direction. Throughout the process, the action of switching the rotation direction of the curling component 3a is executed automatically, eliminating the need for manual adjustment of the curling head's angle or manual operation of multiple buttons, reducing the user's operational difficulty and improving curling efficiency.

[0049] For example, the main body 2a has two hair-receiving slots 22a, namely a first hair-receiving slot 221a and a second hair-receiving slot 222a. The detection component 4a senses the hair to be processed in either the first hair-receiving slot 221a or the second hair-receiving slot 222a. Specifically, the detection component 4a generates a first rotation signal when it senses the hair to be processed in the first hair-receiving slot 221a, and generates a second rotation signal when it senses the hair to be processed in the second hair-receiving slot 222a. The curling component 3a rotates clockwise to wrap the hair according to the first rotation signal, and rotates counterclockwise to wrap the hair according to the second rotation signal. It can be understood that both the clockwise and counterclockwise directions are in the circumferential direction. With this configuration, the curling component 3a can automatically switch rotation directions based on the first or second rotation signal, eliminating the need for the user to manually adjust the angle of the curling head, reducing the difficulty of operation and the possibility of burns, and improving the convenience and efficiency of the curling operation. Furthermore, the detection component 4a automatically sends different signals to the curling component 3a based on which of the two hair receiving slots 22a the hair to be processed is on, so that the rotation direction switching action of the curling component 3a is automatically executed. The user does not need to use multiple buttons to manually switch the rotation direction of the curling component 3a, which reduces the possibility of user misjudgment and failure to curl the hair in the desired direction in time, and improves the accuracy of curling.

[0050] It should be noted that, in Figure 4 In the schematic diagram, the left-side hair-receiving groove 22a is considered as the first hair-receiving groove 221a, and correspondingly, the right-side hair-receiving groove 22a is considered as the second hair-receiving groove 222a. However, this is only an illustrative example and does not limit the specific positions of the first hair-receiving groove 221a and the second hair-receiving groove 222a. That is to say, either of the two hair-receiving grooves 22a can be considered as the first hair-receiving groove 221a, and the other can be considered as the second hair-receiving groove 222a.

[0051] For example, with Figure 4Taking the illustrated method as an example, when the hair stylist curls the hair on the left and right sides of the user's face, the hair on both sides needs to be curled away from the face. If the user is curling the hair on the left side of the face, the hair to be processed can be placed into the second hair container 222a; if the user is curling the hair on the right side of the face, the hair to be processed can be placed into the first hair container 221a, thus creating an "outward curl" effect. Of course, the user can also create an "inward curl" effect as needed, that is, the user can place the hair on the right side of the face into the second hair container 222a and the hair on the left side of the face into the first hair container 221a, in which case the hair on both sides will be curled towards the face. However, regardless of how the user uses the hair styling head 10, the hair stylist can automatically switch the winding direction of the curling component 3a according to which of the two hair containers 22a the hair to be processed is in, without the need for manual switching, reducing the user's operating difficulty and the possibility of misjudgment.

[0052] In some embodiments, such as Figure 5 As shown, the hair styling head 10 also includes a magnetic component 5a, which is disposed on the hair claw 32a. The magnetic component 5a rotates relative to the detection component 4a under the influence of the hair claw 32a. It can be understood that the magnetic component 5a is fixedly connected to the hair claw 32a. The magnetic component 5a is positioned inside the detection component 4a on the hair claw 32a. That is, at least a portion of the magnetic component 5a is located between the opposite ends of the detection component 4a, such that the curling cavity 21a has multiple radial sections that can simultaneously cut through the hair claw 32a, the magnetic component 5a, and the detection component 4a. In these radial sections, the magnetic component 5a is fixed to the position where the hair claw 32a is inside the detection component 4a, and can be opposite to the detection component 4a, so that it can rotate with the hair claw 32a within the detection area of ​​the detection component 4a. Specifically, the magnetic component 5a can be fixed on the inner side of the claw 32a or on the outer side of the claw 32a. However, regardless of whether the magnetic component 5a is fixed on the inner side or the outer side of the claw 32a, as long as the magnetic component 5a can be fixed in the position where the claw 32a is located inside the detection component 4a and can be detected by the detection component 4a, it is acceptable.

[0053] For example, such as Figure 5As shown, the magnetic component 5a can be snapped onto the claw 32a using a snap-fit ​​method, as long as the magnetic component 5a can be fixed onto the claw 32a. For example, a slot can be provided on the side of the claw 32a adjacent to the handle 20, and a gear ring (i.e., driven gear 622) can be snapped into the slot. The claw 32a has a sliding groove 321a on the inner side of the slot and / or the outer side of the gear ring to accommodate the magnetic component 5a. First, the magnetic component 5a is installed into the sliding groove 321a, and then the gear ring is snapped into the base of the claw 32a. At this time, the gear ring (i.e., driven gear 622) abuts against the bottom of the magnetic component 5a, thereby limiting the magnetic component 5a within the sliding groove 321a. When installing the gear ring (i.e., driven gear 622), the fixed installation of the magnetic component 5a is achieved simultaneously.

[0054] Specifically, the detection component 4a can detect changes in the magnetic field based on the Hall effect and convert these changes into an electrical signal output. The Hall effect refers to the voltage difference generated in the direction perpendicular to both the current and the magnetic field when a current flows through a conductor placed in a magnetic field.

[0055] For example, such as Figure 5 and Figure 6 As shown, the detection component 4a and the controller 42 in the component group 4 (refer to...) Figure 6 The electrical connection and detection component 4a may include a Hall element, a signal amplification circuit, a regulated power supply, and an output interface. The Hall element responds to a magnetic field, generating a Hall voltage. The signal amplification circuit enhances the signal to a level recognizable by the controller 42. The regulated power supply ensures the normal operation of the Hall element and the amplification circuit. The output interface is used to output the processed electrical signal to the controller 42.

[0056] like Figure 5 and Figure 6 As shown, the detection component 4a senses and generates a position signal with the magnetic component 5a. The claw 32a resets to its initial position based on the position signal, which is the position of the claw 32a before it is driven. The magnetic component 5a is disposed on the claw 32a and can rotate with the claw 32a. The detection component 4a remains stationary relative to the magnetic component 5a and the claw 32a, that is, the detection component 4a is in a fixed position relative to the magnetic component 5a and the claw 32a. Thus, when the claw 32a drives the magnetic component 5a to rotate, the position of the magnetic component 5a relative to the detection component 4a changes. Specifically, the position relative to the Hall element changes. The detection component 4a detects the change in the magnetic field and generates a corresponding electrical signal, i.e., a position signal, to reflect the current position of the claw 32a.

[0057] It should be noted that, as Figure 5As shown, the initial position can be a pre-set, fixed, safe position where the claw 32a is before it is driven. It is understood that the controller 42 (refer to...) Figure 6 After receiving the position signal, the system can compare the position signal with the initial position to determine whether the claw 32a needs to be reset. If a reset is required, the system controls the claw 32a to rotate. During this process, the detection component 4a can continuously detect the position of the claw 32a based on the position change of the magnetic component 5a and feed it back to the controller 42. The controller 42 thus ensures that the claw 32a is accurately reset.

[0058] For example, at least a portion of the magnetic element 5a is located within the circumference of the detection component 4a. This allows the detection component 4a to accurately sense changes in the position of the magnetic element 5a.

[0059] The hair styling device provided in this embodiment of the invention detects the position of the hair claw 32a by cooperating with the detection component 4a and the magnetic component 5a. The hair claw 32a returns to its initial position according to the position signal. In this way, the hair styling device can automatically return to a fixed safe position after each use, accurately control the position of the hair claw 32a, reduce the risk of improper operation by the user, and improve the user experience. The reset of the hair claw 32a does not require manual rotation or button triggering, and the hair styling device has high safety and convenience.

[0060] In some embodiments, such as Figure 6 and Figure 7 As shown, component group 4 includes a motor 41 and a controller 42. The motor 41 is connected to the claw 32a for driving the claw 32a to rotate. The controller 42 is electrically connected to the detection component 4a and the motor 41 to receive a presence signal and control the motor 41. A transmission component 6 is connected between the output shaft of the motor 41 and the claw 32a. The transmission component 6 has at least a first transmission unit 61 and a second transmission unit 62. The power of the motor 41 is output to the claw 32a sequentially via the first transmission unit 61 and the second transmission unit 62, and the transmission ratio of the first transmission unit 61 and the second transmission unit 62 is greater than 1.

[0061] In the transmission direction along the output shaft of motor 41 to the claw 32a, the input speed is greater than the output speed. With a constant power, torque is negatively correlated with speed; therefore, both the first transmission unit 61 and the second transmission unit 62 output low speed and high torque. Specifically, the output speed of the first transmission unit 61 is less than the input speed, and the output torque of the first transmission unit 61 is greater than the input torque. When there is no power loss between the output shaft of motor 41 and the first transmission unit 61, the input speed of the first transmission unit 61 equals the output shaft speed of motor 41, and the input torque of the first transmission unit 61 equals the output shaft torque of motor 41. Similarly, the output speed of the second transmission unit 62 is less than the output speed of the first transmission unit 61, and the output torque of the second transmission unit 62 is greater than the input torque. When there is no power loss between the second transmission unit 62 and the claw 32a, the output speed of the second transmission unit 62 equals the speed of the claw 32a, and the output torque of the second transmission unit 62 equals the torque of the claw 32a. This can be simply understood as both the first transmission unit 61 and the second transmission unit 62 employing a "reduction and torque increase" transmission method. The first transmission unit 61 and the second transmission unit 62 provide transmission buffer between the output shaft of the motor 41 and the claw 32a, so that the speed at the output shaft of the motor 41 decreases step by step and the torque increases step by step, reducing the possibility of transmission jamming, reducing friction loss and vibration between the motor 41 and the claw 32a, and enabling greater torque transmission to transmit power more efficiently.

[0062] For example, such as Figure 7 As shown, the transmission assembly 6 includes a first transmission unit 61 and a second transmission unit 62 arranged sequentially along the power transmission path. The first transmission unit 61 can be implemented by an independent reduction mechanism, such as a reduction gearbox 611. The reduction gearbox 611 is connected to the motor 41, and the power output by the motor 41 is first reduced in speed and increased in torque by the reduction gearbox 611, thereby realizing the transmission function of the first transmission unit 61. The reduction gearbox 611 is connected to a drive gear 621, and the pawl 32a is connected to a driven gear 622. The drive gear 621 and the driven gear 622 mesh, forming the second transmission unit 62. The power transmitted to the motor 41 on the reduction gearbox 611 is then sequentially transmitted to the drive gear 621 and the driven gear 622, realizing a second reduction in speed and increased torque. In other words, in this embodiment, the power of the motor 41 is sequentially transmitted to: the first transmission unit 61 (reduction gearbox 611), the second transmission unit 62 (a gear pair consisting of a meshing drive gear 621 and a driven gear 622), and the actuator 32a. Further, the driven gear 622 can be a gear ring to form an inner and outer meshing structure with the drive gear 621; the reduction gearbox 611 can be controlled by software to adjust the transmission speed ratio from the motor 41 to the actuator 32a.

[0063] In some possible implementations, the second transmission unit 62 can also be implemented by a planetary gear system. For example, the driving gear 621 can serve as the sun gear of the planetary gear system, the driven gear 622 can serve as the ring gear, and at least one planet gear supported by a planet carrier is provided between the sun gear and the ring gear. In this case, the planetary gear system acts as a whole to realize the speed reduction transmission function of the second transmission unit 62. That is, in this embodiment, the power of the motor 41 is transmitted sequentially to: the first transmission unit 61 (reduction gearbox 611), the second transmission unit 62 (a planetary gear system consisting of the driving gear 621, at least one planet gear, and the driven gear 622), and the pawl 32a.

[0064] In other implementation schemes, such as Figure 6 As shown, the transmission assembly 6 can omit the independent reduction gearbox and be directly composed of two transmission units. For example, the first transmission unit 61 can be implemented by a planetary gear train (the output of the motor 41 is connected to its sun gear), and the second transmission unit 62 can be implemented by a pair of meshing spur gears (or another planetary gear train). Power is transmitted sequentially to the pawl 32a through these two transmission units, completing two-stage reduction. That is, in this embodiment, the power of the motor 41 is transmitted sequentially to: the first transmission unit 61 (a planetary gear train connected to the output shaft of the motor 41), the second transmission unit 62 (a pair of meshing spur gears or another planetary gear train), and the pawl 32a.

[0065] Of course, the transmission assembly 6 can also include N (N>2) transmission units, each with a transmission ratio greater than 1. On the power transmission path of the N transmission units, the first transmission unit is connected to the output shaft of the motor 41, and the last transmission unit is connected to the claw 32a, thereby completing N (N>2) stages of speed reduction on the path from the motor 41 to the claw 32a.

[0066] In some embodiments, such as Figure 7 As shown, the output shaft of motor 41 is driven by a second connector 51, the claw 32a is driven by a first connector 11, and the transmission assembly 6 is connected to the first connector 11 and the second connector 51. One of the first connector 11 and the second connector 51 is provided with a shaft hole 111, and the other of the first connector 11 and the second connector 51 is inserted into the shaft hole 111.

[0067] For example, the first connector 11 can be configured as a column, and the second connector 51 can have a corresponding shaft hole 111, allowing the first connector 11 to be inserted into the second connector 51. Alternatively, in some possible implementations, the second connector 51 can also be configured as a column, and the first connector 11 can have a corresponding shaft hole 111, allowing the second connector 51 to be inserted into the first connector 11. Regardless of the specific structure of the first connector 11 and the second connector 51, as long as they can be inserted, it is acceptable. It can be understood that after the first connector 11 and the second connector 51 are inserted, they are locked in the circumferential direction, thus transmitting torque.

[0068] For example, such as Figure 7 , Figure 15 and Figure 16 As shown, in order to increase the stability of torque transmission, the cross-sectional shape of the shaft hole 111 can also be set as a polygon. For example, the cross-sectional shape of the shaft hole 111 can be a quadrilateral, a pentagon, a hexagon, etc.

[0069] Specifically, in Figure 7 In the schematic diagram shown, the first connector 11 has a shaft hole 111 with a pentagonal cross-section. A portion of the second connector 51 is a pentagonal prism, and this pentagonal prism portion of the second connector 51 is inserted into the shaft hole 111. The first connector 11 circumferentially covers the second connector 51, enabling it to support and limit the second connector 51 at any position in the circumferential direction. This results in higher stability, reduces power loss (such as wear and / or vibration) in the transmission from the motor 41 to the claw 32a, and improves transmission efficiency. Figure 15 and Figure 16 In the schematic diagram shown, the second connector 51 has a shaft hole 111 with a pentagonal cross-section. A portion of the first connector 11 is a pentagonal prism, and this pentagonal prism portion is inserted into the shaft hole 111. It can be understood that in an implementation where a handle 20 is equipped with multiple hair styling heads 10, the end of the idle hair styling head 10 connected to the handle 20 is directly exposed to the external environment. Since the handle 20 is generally not idle, the shaft hole 111 on the second connector 51 reduces the possibility of dust and grime entering and clogging the shaft hole 111, thus facilitating smooth insertion of the first connector 11 and the second connector 51.

[0070] Thus, users only need to plug and unplug to install the hair styling head 10 onto the handle 20, or to separate the hair styling head 10 from the handle 20. Compared to the implementation method where the handle 20 and the hair styling head 10 are assembled through a threaded connection structure, the axial insertion of the handle 20 and the hair styling head 10 provided in this embodiment of the invention is more convenient for users to operate and less strenuous. Users do not need to twist the hair styling head 10, making the operation simple and convenient for users to install and disassemble the hair styling head 10.

[0071] In some embodiments, such as Figure 5 As shown, the hair curling component 3a also includes an end cap component 33a, which is disposed at the free end of the heating rod 31a. The end cap component 33a has a hollow cavity 331a for heat insulation.

[0072] Understandably, the end cap assembly 33a is located on the open side of the curling chamber 21a. During use, the end cap assembly 33a isolates the heating rod 31a from the user's scalp, preventing direct contact between the heating rod 31a and the user's scalp. Furthermore, the hollow cavity 331a of the end cap assembly 33a also isolates the heat generated by the heating rod 31a, meaning the end of the end cap assembly 33a furthest from the heating rod 31a (the upper end) also has a lower temperature. This reduces the impact of the heat generated by the heating rod 31a on the user's scalp, thereby improving the user experience.

[0073] The material of the end cap assembly 33a is not limited. For example, the end cap assembly 33a can be made of a material with heat insulation properties, thereby further improving the heat insulation effect of the end cap assembly 33a. The end cap assembly 33a can also be made of a material with certain temperature resistance properties. It is understood that since the heating rod 31a generates heat, the end cap assembly 33a may experience reliability issues such as local melting under the action of this heat. Using an end cap assembly 33a made of a material with certain temperature resistance properties is beneficial to improving the reliability of the end cap assembly 33a.

[0074] The molding method of the hollow cavity 331a is not limited. In some embodiments, the end cap assembly 33a can be 3D printed to obtain the hollow cavity 331a. Here, the end cap assembly 33a is a one-piece molded structure, which helps to simplify the assembly efficiency of the heating rod 31a.

[0075] In some embodiments, such as Figure 2 and Figure 8As shown, the hair styling head 10 can also be a straightening head. The hair styling head 10 includes a housing 2b, a straightening component 3b, and a resetting component 4b. The housing 2b has a hollow interior forming a receiving cavity 21b for accommodating and mounting other parts. The shape of the housing 2b can be designed according to factors such as aesthetics, practicality, and ease of processing. In this embodiment of the invention, the housing 2b is exemplified as being cylindrical, with a hollow interior forming the receiving cavity 21b. Furthermore, at least one end of the housing 2b is provided with an opening communicating with the receiving cavity 21b, through which other parts are mounted into the receiving cavity 21b.

[0076] Specifically, such as Figure 2 and Figure 8 As shown, the hair straightening component 3b is used for hair styling. The hair straightening component 3b is disposed within the receiving cavity 21b, and at least two are arranged opposite each other. At least one of the two hair straightening components 3b is movable to reciprocate relative to the housing 2b. A hair-holding gap 30b is provided between the two oppositely arranged hair straightening components 3b. The hair to be treated is inserted into the hair-holding gap 30b, whereby the two oppositely arranged hair straightening components 3b jointly clamp the hair, styling it to a straight state.

[0077] Under this implementation, the "shaping parameter" can be the size of the hair-holding gap 30b between the two straightening components 3b, which is the volume of hair that can be placed between the two straightening components 3b. This can be simply understood as the "hair-clamping capacity" of the straightener. Parameters affecting the hair-clamping capacity can be the axial length of the straightening component 3b, the radial width of a single straightening component 3b, or the furthest distance between the two straightening components 3b when they are relatively far apart (i.e., the maximum thickness of the hair-holding gap 30b). Adjusting these parameters can accommodate both long and short hair, and can also cater to multiple users with different hair thicknesses.

[0078] In this embodiment of the invention, two opposing straightening components 3b are configured to maintain a hair-clamping state. That is, under normal conditions, the two opposing straightening components 3b tend to move closer together, allowing them to maintain contact or have a certain thickness of hair-holding gap 30b. The thickness of this gap 30b does not affect the clamping force generated by the two straightening components 3b when hair is inserted between them, thus clamping the hair. By configuring the two opposing straightening components 3b in a hair-clamping state, the system can automatically clamp the hair inserted between them and automatically adjust the space for accommodating the hair, eliminating the need for manual operation. Compared to a straightening head that opens at one end and requires manual clamping to close, this straightening head automatically clamps the hair simply by inserting it, making operation much more convenient.

[0079] The two opposing hair straightening components 3b are configured to maintain a clamping state. This can be achieved by the hair straightening components 3b themselves possessing elastic deformation properties. By limiting the installation position of the hair straightening components 3b, they are either in contact with each other or have a hair-accommodating gap 30b of a certain width. When hair is inserted between the two hair straightening components 3b, it will compress the two components, causing elastic deformation to accommodate the inserted hair. Furthermore, the hair straightening components 3b themselves, by restoring their elastic deformation, can generate a clamping force on the hair, maintaining it in a clamped state. Thus, the elastic deformation properties of the hair straightening components 3b themselves enable the two opposing hair straightening components 3b to maintain a hair-clamping state.

[0080] In some embodiments, such as Figure 8 As shown, a reset member 4b is provided within the receiving cavity 21b. This reset member 4b generates a driving force to drive the two opposing straightening components 3b to maintain the hair clamping state. The reset member 4b is located within the receiving cavity 21b and can be directly connected to the housing 2b; alternatively, it can be close to the housing 2b but with a small gap and not in direct contact. After hair is inserted between the two straightening components 3b, the straightening components 3b are squeezed and come into contact with the reset member 4b, thereby causing the reset member 4b to be subjected to force, which pushes the straightening components 3b to move back to their initial state, thus enabling the two opposing straightening components 3b to be held in the clamping state.

[0081] Specifically, the reset member 4b can generate a driving force, thereby driving the straightening component 3b to move and remain in a clamping state. To reliably maintain the clamping state of the two opposing straightening components 3b, at least one of the two opposing straightening components 3b can be provided with a reset member 4b. Under the driving force generated by the reset member 4b, at least that straightening component 3b can move closer to the other straightening component 3b, achieving the clamping function. Alternatively, each of the two opposing straightening components 3b can be provided with a reset member 4b, and the reset members 4b can be connected to their respective straightening components 3b. In this way, the movement between the two straightening components 3b can be driven by the corresponding reset members 4b, either moving closer or further apart. When they are relatively far apart, the gap formed allows hair to be inserted, while when they are relatively close, the inserted hair can be clamped.

[0082] By setting the reset member 4b, at least one straightening component 3b can be driven to move relative to the other straightening component 3b. In this way, when processing hair, it is only necessary to put the hair between the two straightening components 3b, and the reset member 4b can clamp the put-in hair, so that no manual force is required to clamp the hair, simplifying the operation and improving the convenience of use.

[0083] The reset member 4b can be a mechanism that provides telescopic movement when energized, such as a motor 41 lead screw mechanism or telescopic rod. In this case, the movement of the hair straightening component 3b can be automatically controlled by detecting whether hair is inserted. In this embodiment of the invention, the reset member 4b is set as a part that generates driving force by its own elastic deformation, such as a spring or a spring sheet. It is set to keep the reset member 4b in a compressed state under normal conditions, so as to maintain the force of restoring deformation. Under this force, the connected hair straightening component 3b moves in the direction of the other hair straightening component 3b, that is, the two hair straightening components 3b remain close to each other under normal conditions, forming a clamping state.

[0084] In some embodiments, such as Figure 1 and Figure 8As shown, a notch 22b is provided on the housing 2b to allow hair to be inserted between the two straightening components 3b. Specifically, the notch 22b is located on the side wall of the housing 2b, allowing the hair to be processed to be inserted through the notch 22b into the hair-holding gap 30b between the two opposing straightening components 3b and held in place. The position of the notch 22b on the housing 2b can be opposite to the gap formed by the relative opening between the two straightening components 3b, thus facilitating direct insertion of the hair. Of course, it can also be provided in other positions without being opposite, as long as the hair can be inserted. Alternatively, two notches 22b can be provided opposite to each other on the housing 2b, with each notch 22b corresponding to the gap formed by the relative opening between the two straightening components 3b. In this way, longer hairs can be placed on opposite sides of the housing, and continuous straightening of the hair can be achieved by moving the straightening head relative to the held hair, improving the ease of operation. In this configuration, the opening at one end of the housing 2b can be flared to guide the hair into the space between the two straightening components 3b.

[0085] This invention provides a hair straightener comprising a housing 2b, straightening components 3b, and a resetting member 4b. The housing 2b has an internal receiving cavity 21b, within which the straightening components 3b are disposed. At least two straightening components 3b are arranged opposite each other, with the two opposing straightening components 3b positioned in a clamping state capable of holding hair. The resetting member 4b drives the two opposing straightening components 3b to remain in the clamping state. Thus, because the two straightening components 3b remain close together, the hair inserted between them is automatically clamped, and the clamping space is automatically adjusted. Driven by the resetting member 4b, the clamping state is maintained at all times, eliminating the need for manual force to clamp the hair. This simplifies the hair styling process, making it easy for users and improving the user experience.

[0086] In some embodiments, such as Figure 8 As shown, each hair straightening component 3b is equipped with at least two reset members 4b, which are spaced apart. This arrangement ensures that each hair straightening component 3b has at least two reset members 4b to provide driving force. This relatively large driving force allows the hair straightening component 3b to move reliably and maintain its hair-clamping state, thus achieving reliable hair clamping. Specifically, the multiple reset members 4b connected to each hair straightening component 3b can be evenly spaced to ensure balanced force distribution, thereby improving the smoothness and stability of the hair straightening component 3b's movement. Moreover, driven by multiple reset members 4b, even if a single reset member 4b fails, the hair straightening component 3b can still be driven to move, enhancing the reliability of its hair-clamping movement.

[0087] In some embodiments, such as Figure 8 As shown, since the hair straightener 3b generates heat when powered on, this heat is transferred to the housing 2b during use, especially for extended periods, causing the housing 2b to heat up and affecting the user's grip. Therefore, in this embodiment of the invention, a heat insulation component 5b is provided between the housing 2b and the hair straightener 3b. This heat insulation component 5b at least serves to block the transfer of heat from the hair straightener 3b to the housing 2b. That is, the heat generated by the hair straightener 3b is blocked by the heat insulation component 5b, preventing it from being directly transferred to the housing 2b. Instead, the heat generated by the hair straightener 3b is blocked by the heat insulation component 5b, requiring it to be transferred to the heat insulation component 5b before it can be transferred to the housing 2b. This reduces the temperature of the housing 2b, effectively preventing high temperatures on the housing 2b from affecting the user's grip or causing safety hazards due to excessively high temperatures. The heat insulation element 5b effectively blocks the possibility of heat transfer to the housing 2b, thus improving the comfort and safety of using the hair straightener.

[0088] When a heat insulation component 5b is provided, it is closer to the hair straightening assembly 3b than the housing 2b, allowing the reset component 4b to be positioned between the heat insulation component 5b and the hair straightening assembly 3b. Thus, the reset component 4b can directly act on the hair straightening assembly 3b. Furthermore, to improve the reliability of the reset component 4b's installation position, a receiving groove can be provided on the heat insulation component 5b, with one end of the reset component 4b fixed within the receiving groove and the other end connected to the hair straightening assembly 3b. This way, the receiving groove limits the installation position of the reset component 4b, ensuring its stability and preventing offset, thus reliably driving the movement of the hair straightening assembly 3b.

[0089] Optionally, to improve the heat insulation effect of the heat insulation component 5b, it can be made of a material with low thermal conductivity, thereby reliably achieving the heat insulation effect. Moreover, the heat insulation component 5b also serves as part of the shell 2b of the hair straightener, thereby improving the overall structural strength of the hair straightener.

[0090] Specifically, the heat insulation component 5b is disposed between the hair straightening assembly 3b and the housing 2b. The heat insulation component 5b can be connected to the housing 2b, while the hair straightening assembly 3b can be connected to the housing 2b and / or the heat insulation component 5b. The hair straightening assembly 3b can be installed and fixed in various ways to meet different design requirements.

[0091] In some embodiments, such as Figure 2 and Figure 8As shown, the hair straightening assembly 3b includes a heating element 31b and a fixing shell 32b. The heating element 31b is used to heat the hair to improve the effect of hair styling. The fixing shell 32b is movably disposed within the housing 2b. The heating element 31b is mounted on the fixing shell 32b and at least partially protrudes from it, allowing the inserted hair to contact the exposed heating element 31b for heating. The heating element 31b can be an object that generates heat when energized, such as an electric heating plate, electric heating wire, or electric plate, and is shaped according to design requirements. The heating element 31b is mounted on the fixing shell 32b and at least partially protrudes from it. In this way, the fixing shell 32b provides support for the mounting position of the heating element 31b. When energized, the heating element 31b heats up and can directly contact the hair for heat treatment. The reset member 4b abuts against or is connected to the fixed shell 32b. The reset member 4b can drive the fixed shell 32b to move, thereby driving the heating member 31b to move synchronously. This allows for adjustment of the position of the hair to be accommodated and for maintaining the clamping of the inserted hair, ensuring that the hair is always in a clamping state.

[0092] The heating element 31b and the fixing shell 32b can be installed by snap-fitting or by using screws or similar fasteners. Alternatively, the fixing shell 32b can be fitted over a portion of the heating element 31b for secure installation. There are various installation methods, as long as the heating element 31b can be reliably fixed and at least a portion of the fixed heating element 31b protrudes outside the fixing shell 32b.

[0093] In some embodiments, such as Figure 9 and Figure 10 As shown, the hair to be processed is typically inserted through the open ends of the two straightening components 3b. Therefore, an anti-clamping gap 6b is provided at least between the fixing shell 32b and the heating element 31b at the end for inserting the hair to prevent hair from getting stuck. That is, the fixing shell 32b and the heating element 31b at the open end are spaced apart, so that even if hair enters the anti-clamping gap 6b, the width of the anti-clamping gap 6b is greater than the thickness of the hair, allowing the hair to move freely within the anti-clamping gap 6b and preventing the hair from getting stuck. In other words, during use, hair that enters the anti-clamping gap 6b can smoothly detach from it without getting stuck, effectively avoiding the pulling and pain caused by stuck hair and improving the user's actual comfort.

[0094] In some embodiments, two heating elements 31b may be used to abut against each other at the ends where the hair is inserted. In this way, after the hair is inserted between the two heating elements 31b, the hair can be heated from two opposite sides by the two heating elements 31b, so that the hair can be heated evenly and the heating efficiency of the hair can be improved, thereby improving the effect of heating the hair.

[0095] Specifically, the width of the anti-pinch gap 6b can be reasonably designed based on the diameter of a typical hair. In this embodiment of the invention, the width of the anti-pinch gap 6b is set to a range of 0.3mm to 0.6mm. For example, it can be 0.3mm, 0.4mm, 0.45mm, 0.5mm, or 0.6mm. It can also be any other value within the range of 0.3mm to 0.6mm. Thus, the width of the anti-pinch gap 6b is several times larger than the diameter of a hair, thereby not only reliably preventing hair from being pinched, but also effectively avoiding affecting the product's aesthetics due to an excessively large gap size, ensuring the product's appearance integrity and quality.

[0096] In some embodiments, such as Figure 8 and Figure 11 As shown, the fixed shell 32b includes a first shell 321b and a second shell 322. The first shell 321b and the second shell 322 mainly serve as the shell 2b part, providing mounting support for the heating element 31b. The first shell 321b is provided with a first splicing structure 3211b, and the second shell 322 is provided with a second splicing structure 3221b. The first splicing structure 3211b and the second splicing structure 3221b are detachably connected. This allows the first shell 321b and the second shell 322 to be easily assembled and connected to each other. Specifically, by setting the fixed shell 32b into a first shell 321b and a second shell 322 that can be spliced ​​to each other for the installation of the heating element 31b, the manufacturing and processing difficulty of the fixed shell 32b is reduced, and the ease of assembly and connection is improved compared to using an integrated fixed shell 32b structure. In other words, compared to the longer integrated fixed shell 32b, the split fixed shell 32b reduces the manufacturing difficulty in achieving overall flatness consistency. It can also be installed separately during assembly, reducing the operating space required and simplifying assembly. Furthermore, the split first shell 321b and second shell 322 are respectively equipped with splicing structures, enabling simple and convenient splicing between the two. After splicing, the connection is stable and not easily loosened, thus better ensuring the overall structural robustness and meeting the product's strength requirements.

[0097] Of course, in some embodiments, the fixed shell 32b can also be configured to be formed by splicing more splicing units (such as the first shell 321b, the second shell 322, the third shell, etc.) together, and the splicing units are connected to each other by setting splicing structure to form a whole.

[0098] Specifically, the first splicing structure 3211b on the first shell 321b and the second splicing structure 3221b on the second shell 322 can be configured as a matching hook assembly structure, a tenon and mortise structure, or a flexible plug-in structure, etc., so that the first shell 321b and the second shell 322 can be quickly assembled and connected when they are spliced ​​together. Compared with the connection by screws or glue, no assembly operations are required, and the connection is convenient.

[0099] In some embodiments, such as Figure 11 As shown, the heating element 31b is provided with a first connecting structure 311b, and both the first shell 321b and the second shell 322 are provided with a second connecting structure 323b. The first connecting structure 311b and the second connecting structure 323b are connected to each other. That is, both the first shell 321b and the second shell 322 are provided with a second connecting structure 323b, which can be connected to the first connecting structure 311b on the heating element 31b. In this way, the heating element 31b can be fixedly installed on the first shell 321b and the second shell 322, which is convenient, stable and reliable.

[0100] Specifically, the first connecting structure 311b can be configured as a sliding groove 321a, and the second connecting structure 323b can be configured as a connecting block that can be inserted into the sliding groove 321a to achieve connection. The first connecting structure 311b can also be configured as a hook, and the second connecting structure 323b can be configured as a snap-fit ​​position for hook connection. The first connecting structure 311b can also be configured as a plug, and the second connecting structure 323b can be configured as a plug hole for plug insertion and locking connection. Of course, it is understandable that the configuration of the first connecting structure 311b and the second connecting structure 323b can be interchanged, provided that a proper fit is achieved. This method of achieving assembly connection between the fixed shell 32b and the heating element 31b through connecting structures not only facilitates connection and requires minimal operation, improving assembly convenience, but also ensures high connection reliability, preventing loosening and improving product quality stability.

[0101] In other embodiments, a first connecting structure 311b may be provided on the heating element 31b, one of the first shell 321b and the second shell 322 may be integrally formed with the heating element 31b, and a second connecting structure 323b may be provided on the other of the first shell 321b and the second shell 322. The heating element 31b then has the first connecting structure 311b, and the first connecting structure 311b and the second connecting structure 323b are connected together. That is, either the first shell 321b or the second shell 322 is integrally formed with the heating element 31b, while the other shell is detachably connected to the heating element 31b via a matching connecting structure. The two fixed shells 32b are still connected by a splicing structure. This allows for quick assembly and connection with good reliability.

[0102] In this invention, the fixing shell 32b is configured as a first shell 321b and a second shell 322 that can be spliced ​​together. The first shell 321b and the second shell 322 are detachably connected through a splicing structure, making the connection operation simple and convenient. Furthermore, a first connecting structure 311b is provided on the heating element 31b, and a second connecting structure 323b is provided on both the first shell 321b and the second shell 322; or one of the first shell 321b and the second shell 322 is integrally formed with the heating element, and the other of the first shell 321b and the second shell 322 is also provided with a second connecting structure 323b. Thus, the installation of the separately configured fixing shell 32b can be achieved through the mutual connection of the first connecting structure 311b and the second connecting structure 323b, without the need for screws or adhesive, making the connection convenient.

[0103] In some embodiments, such as Figure 6 and Figure 12 As shown, the handle 20 includes an inner shell 7, an outer shell 8, and a bottom cover 9. The inner shell 7 forms a receiving space 71, within which the component assembly 4 is installed. The receiving space 71 can be a cavity with a continuous circumferential profile, or it can be one or more opening slots with a discontinuous circumferential profile. It is understood that the shape, structure, and formation of the receiving space 71 can have various embodiments. This invention does not impose further limitations on the receiving space 71, as long as it is capable of housing the component assembly 4.

[0104] The outer shell 8 encloses a mounting cavity 81 with openings at both ends, and is fitted over the inner shell 7. Specifically, the outline of the outer shell 8 surrounds the inner shell 7 circumferentially and radially. The outer shell 8 is closer to the external environment than the inner shell 7, and its outer outline at least partially forms the outer outline of the handle 20, allowing it to be directly observed with the naked eye from the outside of the hair stylist. The structure and shape of the outer shell 8 define the shape and size of the inner shell 7. That is, the outer shell 8 is hollow and roughly cylindrical, and the maximum diameter of the inner shell 7 does not exceed the diameter of the mounting cavity 81 formed by the outer shell 8, i.e., the inner diameter of the outer shell 8, so that the inner shell 7 passes through the mounting cavity 81 of the outer shell 8. Simply put, the outer shell 8 circumferentially covers the inner shell 7.

[0105] It should be noted that the embodiments of the present invention do not limit the cross-sectional shape of the outer shell 8 and the inner shell 7 in the radial direction. The cross-sectional shape can be square, circular, elliptical, etc., and the direction of the diameter can represent the straight line direction within any cross-section perpendicular to the axial direction and passing through the midpoint.

[0106] The hair styling head 10 and the bottom cover 9 are correspondingly connected to the outer casing 8 to respectively seal the opening of the mounting cavity 81. The bottom cover 9 is provided with a power supply component 91, which is used to connect a power supply device to charge the component assembly 4 or to power the component assembly 4 for use. The power supply device can be a socket to provide AC220V alternating current, i.e., mains power, to the hair styling device so that the component assembly 4 can be powered and / or charged for use.

[0107] When the hair styling device is plugged in, the power supply component 91 can be a power cord with a plug for connection to AC power in a socket. When the hair styling device is charged, component group 4 also includes a battery, and the power supply component 91 includes a charging terminal and a charging cable, which together form the aforementioned power connection component. The charging terminal is located on the bottom cover 9 and is electrically connected to the battery. The charging cable is detachably connected to the charging terminal to charge the battery. In other words, the hair styling device in this embodiment can be used with stored electricity, eliminating the need for continuous connection to a socket, thus increasing the applicable scenarios for the hair styling device and making it more convenient for users.

[0108] In some embodiments, such as Figure 12 As shown, the inner shell 7 and the outer shell 8 are connected by a connector (not shown in the figure), which is located between the outer shell 8 and the inner shell 7. The assembly gap between the connector and the outer shell 8 and the inner shell 7 is also hidden inside the outer shell 8 and is not exposed on the outer contour of the hair stylist, further reducing the assembly gap on the outer contour of the hair stylist and improving the appearance and shape coordination of the hair stylist.

[0109] Specifically, the connector can be a threaded fastener such as a screw, bolt, or bolt; it can also be a fastener without threads such as a pin or wedge; or it can be a snap-fit ​​component such as a clip or a self-locking elastic component. Some implementation schemes will be described as examples in the following embodiments. It should be noted that the embodiments of the present invention do not limit the specific structure of the connector, as long as the connector can connect the inner shell 7 and the outer shell 8.

[0110] For example, such as Figure 3 As shown, the inner shell 7 has a first mounting hole 72, and the outer shell 8 has a second mounting hole 82 coaxial with the first mounting hole 72. Both the first mounting hole 72 and the second mounting hole 82 extend axially. The connecting member is a threaded fastener, which passes through the first mounting hole 72 and the second mounting hole 82. Specifically, the first mounting hole 72 and the second mounting hole 82 can be provided in multiple sets to improve the stability of the connection between the inner shell 7 and the outer shell 8.

[0111] In some embodiments, such as Figures 12-14 As shown, the outer shell 8 has a first end 83 and a second end 84 that are axially opposite each other, and the inner shell 7 has a third end 73 and a fourth end 74 that are axially opposite each other. The third end 73 of the inner shell 7 is rotatably fixed to the hair styling head 10, the first end 83 of the outer shell 8 is connected to the hair styling head 10 or the inner shell 7, and the connector (the position where the first mounting hole 72 and the second mounting hole 82 are connected) is adjacent to the second end 84.

[0112] The first end 83 is connected to the hair styling head 10 or the inner shell 7, the second end 84 is connected to the fourth end 74 via a connector, and the third end 73 is rotatably fixed to the hair styling head 10. Specifically, the first end 83 indicates the position where the outer shell 8 is connected to the hair styling head 10 or the inner shell 7, the second end 84 indicates the position where the outer shell 8 is connected to the inner shell 7; similarly, the third end 73 indicates the position where the inner shell 7 is connected to the hair styling head 10, and the fourth end 74 indicates the position where the inner shell 7 is connected to the outer shell 8. The first end 83 of the outer shell 8 can be connected to either the hair styling head 10 or the inner shell 7, but regardless of whether the first end 83 is connected to either the hair styling head 10 or the inner shell 7, after the third end 73 is rotatably fixed to the hair styling head 10, the inner shell 7 and the hair styling head 10 are locked in the circumferential direction and cannot rotate relative to the hair styling head 10. The second end 84 and the fourth end 74 are also fixed via a connector, so that the outer shell 8 and the inner shell 7 are both fixedly connected, making it impossible for the outer shell 8 to rotate relative to the hair styling head 10.

[0113] With this configuration, the connector connects the second end 84 and the fourth end 74, away from the position where the handle 20 connects to the hair styling head 10. The first end 83 and the third end 73 do not require pre-reserved positions for the connector installation, reducing the number and layers of assembly gaps between the handle 20 and the hair styling head 10. This not only simplifies the assembly process but also reduces the possibility of water and dust entering the connection point, helping to maintain the reliability of the electrical connection between the handle 20 and the hair styling head 10 and facilitating cleaning of the connection point. Furthermore, since the handle 20 is fixed to the hair styling head 10 at the third end 73 of the inner shell 7, regardless of whether the first end 83 is connected to the hair styling head 10 or the inner shell 7, the outer shell 8, after being fixed to the inner shell 7 via the connector, can be fixed to the hair styling head 10, making the structure of the outer shell 8 relatively simple. The inner shell 7 and the outer shell 8 are firmly fixed to the hair styling head 10 as a whole, and the outer shell 8 maintains a relatively simple structure. In other words, the handle 20 provided in this embodiment of the invention is reliably fixed to the hair styling head 10 with a relatively simple structure. The design is ingenious and easy to implement.

[0114] In some embodiments, such as Figures 12-14 As shown, the third end 73 is axially connected to the hair styling head 10 and circumferentially rotates and engages with the hair styling head 10. The first end 83 of the outer shell 8 is connected to the hair styling head 10 to restrict the rotation of the hair styling head 10 relative to the inner shell 7. The fact that the third end 73 can be axially connected to the hair styling head 10 indicates that the hair styling head 10 has a position (e.g., the insertion interface 22) for the inner shell 7 to move axially. The inner shell 7 can move closer to or further away from the hair styling head 10 through this position (e.g., the insertion interface 22). However, after the third end 73 rotates circumferentially, a relative positional change occurs between the inner shell 7 and the hair styling head 10 in the circumferential direction, that is, the inner shell 7 and the hair styling head 10 are misaligned in the circumferential direction, causing the third end 73 to avoid the aforementioned position (e.g., the insertion interface 22) and engage with the hair styling head 10. After the first end 83 is connected to the hair styling head 10, a connection is established between the first end 83 and the hair styling head 10, restricting the rotation of the hair styling head 10. The third end 73 cannot rotate circumferentially to reset, and cannot detach from the hair styling head 10 along its original position (such as the insertion interface 22), thereby fixing the inner shell 7 on the hair styling head 10 and realizing the assembly operation of the hair styling head 10 and the handle 20.

[0115] With this configuration, both the outer shell 8 and the inner shell 7 are connected to the hair styling head 10, and the outer shell 8 and the inner shell 7 are also fixedly connected by a connector. The outer shell 8 and the inner shell 7 together restrict the rotation of the hair styling head 10 and limit each other's movement, resulting in good reliability after the handle 20 is assembled with the hair styling head 10. In addition, the inner shell 7 and the hair styling head 10 are snapped together, resulting in a relatively simple connection structure. Users do not need to twist it many times, which also makes it convenient for users to assemble the hair styling head 10 with the handle 20.

[0116] In some embodiments, such as Figures 12-14 As shown, one of the hair styling head 10 and the inner shell 7 has an insertion interface 22 and a limiting groove 23, while the other of the hair styling head 10 and the inner shell 7 has a protrusion 731. The insertion interface 22 and the limiting groove 23 can be provided on the hair styling head 10, and the protrusion 731 on the inner shell 7; alternatively, the protrusion 731 can be provided on the hair styling head 10, and the insertion interface 22 and the limiting groove 23 can be provided on the inner shell 7. For ease of explanation, the example of the hair styling head 10 having an insertion interface 22 and a limiting groove 23, and the inner shell 7 having a protrusion 731, will be used. The insertion interface 22 extends axially and penetrates the axial portion of the end wall of the hair styling head 10. The limiting groove 23 communicates with the insertion interface 22 and extends circumferentially, i.e., the limiting groove 23 is located circumferentially and is at least arc-shaped. The protrusion 731 is inserted axially into the insertion interface 22 and rotates circumferentially into the limiting groove 23. The protrusion 731 moves axially along the insertion interface 22. After rotation, the protrusion 731 enters the limiting groove 23 through the position where the insertion interface 22 connects with the limiting groove 23. A relative positional change occurs between the protrusion 731 and the insertion interface 22, and the protrusion 731 and the insertion interface 22 are misaligned in the circumferential direction until the protrusion 731 is engaged in the limiting groove 23. At this time, the protrusion 731 cannot detach from the hair styling head 10 along the insertion interface 22, so that the inner shell 7 is fixed on the hair styling head 10, and the outer shell 8 is fixed to the inner shell 7 through the connector, thus fixing it to the hair styling head 10 through the inner shell 7. Thus, the assembly operation of the handle 20 is completed.

[0117] The connector is a threaded fastener, which axially fixes the inner shell 7 and the outer shell 8. Due to the adjustability of the threaded connection, the connector axially tightens the inner shell 7 and the outer shell 8, causing the protrusion 731 within the limiting groove 23 to axially abut against the end wall forming the limiting groove 23, increasing the friction between the protrusion 731 and the end wall forming the limiting groove 23. Due to the self-locking property of the threaded connection, the inner shell 7 and the outer shell 8 are reliably connected, reducing the possibility of them loosening, thereby reducing the possibility of the handle 20 separating from the hair styling head 10, and facilitating a more secure fixation between the handle 20 and the hair styling head 10.

[0118] In some embodiments, such as Figure 3As shown, the hair styling head 10 also includes a first connector 13, and the handle 20 includes a second connector 53. When the first connector 11 and the second connector 51 are plugged in, the first connector 13 and the second connector 53 attract each other to maintain the connection between the hair styling head 10 and the handle 20. The attraction between the first connector 13 and the second connector 53 forms an auxiliary fixing force connecting the hair styling head 10 and the handle 20, ensuring a relatively reliable connection between them and reducing the possibility of separation due to accidental contact or vibration after the handle 20 and hair styling head 10 are connected. In other words, the hair styling device provided by this embodiment of the invention facilitates user assembly and disassembly of the hair styling head 10 while reliably maintaining the stability of the connection between the hair styling head 10 and the handle 20, thus improving the user experience.

[0119] Specifically, the first connector 13 and the second connector 53 can be elastic self-locking structures or magnetic adsorption structures. The embodiments of the present invention do not limit the specific structure of the first connector 13 and the second connector 53, as long as the first connector 13 and the second connector 53 are connected after the handle 20 and the hair styling head 10 are inserted.

[0120] In some embodiments, such as Figure 12 and Figure 13 As shown, one of the hair styling head 10 and the handle 20 has a slot 21 at one end in the axial direction, and the other end of the hair styling head 10 and the handle 20 is inserted into the slot 21 in the axial direction. Alternatively, the hair styling head 10 may have a slot 21, and one end of the handle 20 may be inserted into the slot 21; or the handle 20 may have a slot 21, and one end of the hair styling head 10 may be inserted into the slot 21. To facilitate explanation of the implementation principle of the slot 21, the structure of the hair styling head 10 having a slot 21 and one end of the handle 20 being inserted into the slot 21 in the axial direction will be described. Specifically, the handle 20 may be a columnar body extending in the axial direction, and the diameter of the handle 20 at any position is less than or equal to the inner diameter of the slot 21; of course, the handle 20 may also have a stepped surface, as long as the diameter of the part of the handle 20 connected to the hair styling head 10 is less than or equal to the inner diameter of the slot 21. Regardless of which of the aforementioned embodiments the handle 20 is configured with, at least a portion of the handle 20 is inserted into the slot 21. The slot 21 circumferentially covers at least a portion of the handle 20 to form a circumferential limit on the handle 20. The user can use the slot 21 as an installation reference and insert the handle 20 into the slot 21 to achieve the initial installation of the handle 20 and the hair styling head 10, which is convenient for the user to operate. This configuration is simple in structure, easy to implement, requires no multiple turns of twisting, saves more effort, and can reliably maintain the connection stability between the handle 20 and the hair styling head 10.

[0121] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
