Description

Hair styling tool Technical Field

[0001] This application belongs to the field of hair styling tool technology, and in particular relates to a hair styling device. Background Technology

[0002] In the process of styling hair, curling irons or straighteners are commonly used tools. Users can choose the appropriate tool according to their own styling needs to create the desired hairstyle and enhance their image.

[0003] Curling irons and straighteners achieve their respective hair treatments through different functional heads. In related technologies, the curling or straightening head is fixedly connected to the handle, meaning each product can only perform its corresponding function, resulting in limited functionality. For example, a curling iron can only be used for curling hair, and a straightener can only be used for straightening hair; the heads cannot be interchanged. To meet diverse hair styling needs, users must purchase different types of products. Therefore, existing hair styling products suffer from poor flexibility and cannot meet the diverse needs of users. Summary of the Invention

[0004] In view of this, this application provides a hair styling tool to solve the problem of poor usability and inability to meet the diverse needs of users.

[0005] To solve the above problems, the technical solution of this application is implemented as follows:

[0006] A hair styling device includes: a styling head for receiving and styling hair, the styling head having a first connecting structure; and a handle connected to the styling head to at least support the styling head, the handle having a second connecting structure; wherein at least two styling heads are provided, each styling head having the first connecting structure, the first connecting structure and the second connecting structure being detachably connected to assemble the styling head onto the handle, the styling head being configured to styling hair when the handle controls the styling head, and the handle having a control component for controlling the working state of the styling head.

[0007] This application provides a hair styling device including a styling head and a handle. The styling head has a first connecting structure, and the handle is connected to the styling head to at least support it. The handle has a second connecting structure and a control component, which controls the working state of the connected styling head. By using at least two styling heads, each with a first connecting structure, and the first and second connecting structures being detachably connected, and configuring the styling heads to style hair when controlled by the handle, different types of styling heads can be connected to the handle to achieve different types of hair styling. That is, a single handle can be connected to different styling heads to increase the types of hair that can be styled without changing the handle, improving the flexibility and functionality of the hair styling device and better meeting the diverse needs of users.

[0027] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0028] 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 application will not be described separately.

[0029] 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 orientation under normal use conditions, 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 conditions.

[0030] 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.

[0031] As shown in Figure 1, this application provides a hair styling tool that can be used to style hair, such as straightening or curling it. The hair styling tool includes a styling head 1 and a handle 2. The styling head 1 can be used to straighten or curl hair, and the handle 2 is connected to and supports the styling head 1 for user handheld use. The styling head 1 has a heating function to heat the hair, making it softer and more malleable, thus achieving straight or curly hair.

[0032] Specifically, as shown in Figures 1 and 2, the styling head 1 can accommodate hair, allowing for styling treatment. At least two styling heads 1 are provided (1a and 1b as shown in Figure 1), and each styling head 1 can perform different types of hair treatments; for example, one can straighten the hair, and the other can curl it. Each styling head 1 is provided with a first connecting structure 10, while the handle 2 is provided with a second connecting structure 20 and a control component 26 (see Figure 3). The first connecting structure 10 and the second connecting structure 20 are detachably connected to each other, allowing the styling head 1 to be assembled onto the handle 2. This configures the styling head 1 to perform hair styling treatment when controlled by the handle 2. That is, the first connecting structure 10 and the second connecting structure 20 can be matched and connected, ensuring a stable connection between the styling head 1 and the handle 2. Furthermore, it allows for quick disassembly and separation between the styling head 1 and the handle 2.

[0033] In this way, different styling heads 1 are connected to the handle 2, and under the corresponding control of the control component 26, different types of hair styling treatments can be achieved to meet the diverse needs of users. That is, one handle 2 can be adapted to multiple styling heads 1, eliminating the need to replace the entire hair styling device and reducing the cost for users to meet diverse hairstyle needs. Specifically, by changing different styling heads 1, different types of hair styling needs can be met, eliminating the need to replace the entire hair styling device and satisfying diverse user requirements. Furthermore, the matching connection between the first connecting structure 10 and the second connecting structure 20 allows for quick assembly and disassembly of the styling head 1 and the handle 2, ensuring convenient, stable, and reliable connection, thus effectively meeting usage requirements.

[0034] In some embodiments, as shown in Figures 3 and 4, the handle 2 includes a housing 21 and an inner housing 22. The inner housing 22 forms a receiving space 220 for mounting at least electronic components capable of controlling the operation of the molding head 1, such as circuit boards, control switches, etc. The receiving space 220 can be a cavity with a continuous profile in the circumferential direction, or it can be one or more opening slots with an open profile in the circumferential direction. It is understood that the shape, structure, and formation of the receiving space 220 have various embodiments. This application does not impose further limitations on the receiving space 220, as long as the receiving space 220 can accommodate electronic components.

[0035] Specifically, the outer shell 21 is fitted over the inner shell 22, so that the inner shell 22 is located in the inner cavity of the outer shell 21, and the outer contour of the outer shell 21 at least forms part of the outer contour of the handle 2.

[0036] This application embodiment does not limit the radial cross-sectional shape of the outer shell 21 and the inner shell 22. The cross-sectional shape can be square, circular, elliptical, etc., and the direction of the diameter can represent the straight line direction passing through the midpoint within any vertical axial cross-section. The outer shell 21 is fitted over the inner shell 22, and the outer shell 21 and the inner shell 22 are coaxially fitted. The inner shell 22 can be configured as a parting structure to accommodate and install electronic components. The outer shell 21 covers the inner shell 22 in the circumferential direction, and can at least cover part of the assembly gaps on the inner shell 22, so that at least part of the assembly gaps of the inner shell 22 are not exposed. This reduces the exposed assembly gaps of the product, reduces the possibility of water and dust entering the handle 2, helps to maintain a more reliable connection of the circuit inside the handle 2, and also facilitates cleaning.

[0037] In some embodiments, as shown in Figures 3 and 4, the outer shell 21 has a first end 211 and a second end 212 that are axially opposed, and the inner shell 22 has a third end 221 and a fourth end 222 that are axially opposed. It should be noted that the ends represent the axial contour edge positions of the outer shell 21 and the inner shell 22, or positions axially close to the contour edge. For example, the first end 211 represents the axial contour edge position of the outer shell 21, and the second end 212 represents the position close to the axial contour edge of the outer shell 21 opposite to the first end 211; similarly, the third end 221 represents the axial contour edge position of the inner shell 22, and the fourth end 222 represents the position close to the axial contour edge of the inner shell 22 opposite to the third end 221.

[0038] As shown in Figures 3 and 4, the first end 211 is connected to the molding head 1 (refer to Figure 1) and / or the inner shell 22, the second end 212 is connected to the fourth end 222 via a connector (not shown in the figure), and the third end 221 is rotatably fixed to the molding head 1. Specifically, the first end 211 indicates the position where the outer shell 21 is connected to the molding head 1 or the inner shell 22, the second end 212 indicates the position where the outer shell 21 is connected to the inner shell 22; similarly, the third end 221 indicates the position where the inner shell 22 is connected to the molding head 1, and the fourth end 222 indicates the position where the inner shell 22 is connected to the outer shell 21. The first end 211 of the outer shell 21 can be connected to the molding head 1 or the inner shell 22. Alternatively, the first end 211 of the outer shell 21 can be connected to both the molding head 1 and the inner shell 22. After the third end 221 is rotated and fixed to the molding head 1, the inner shell 22 is locked in the circumferential direction with the molding head 1 and cannot rotate relative to the molding head 1. The second end 212 and the fourth end 222 are fixed by a connector. The outer shell 21 and the inner shell 22 are both fixedly connected, so that the outer shell 21 cannot rotate relative to the molding head 1.

[0039] The connector connects the second end 212 and the fourth end 222, and is located away from the position where the handle 2 connects to the molding head 1. The first end 211 and the third end 221 do not require pre-reserved positions for the connector installation, reducing the number and layers of assembly gaps between the handle 2 and the molding head 1. This not only simplifies assembly but also reduces the possibility of water and dust entering the connection point, facilitating the reliability of the electrical connection between the handle 2 and the molding head 1, and making cleaning the connection point easier. Furthermore, since the handle 2 is fixed to the molding head 1 at the third end 221 of the inner shell 22, regardless of whether the first end 211 is connected to the molding head 1 or the inner shell 22, the outer shell 21, after being fixed to the inner shell 22 via the connector, can be fixed to the molding head 1, making the structure of the outer shell 21 relatively simple. The inner shell 22 and the outer shell 21 are firmly fixed to the molding head 1 as a whole, and the outer shell 21 maintains a relatively simple structure.

[0040] The connector can be a screw, bolt or other threaded fastener, or a pin, wedge or other unthreaded fastener, or a snap-fit ​​or other snap-fit ​​component. The embodiments of this application do not limit the specific structure of the connector, as long as the connector can connect the second end 212 and the fourth end 222, thereby connecting the inner shell 22 and the outer shell 21.

[0041] In some embodiments, as shown in Figures 3 and 4, the third end 221 is axially connected to the molding head 1 (see Figure 1) and circumferentially engaged with the molding head 1. The first end 211 is connected to the molding head 1 to restrict the rotation of the molding head 1 relative to the inner shell 22. The fact that the third end 221 can be axially connected to the molding head 1 indicates that the molding head 1 has a position for the inner shell 22 to move axially (e.g., a hole for the third end to be inserted), through which the inner shell 22 can move axially closer to or further away from the molding head 1. However, after the third end 221 rotates circumferentially, the relative position between the inner shell 22 and the molding head 1 changes circumferentially, that is, the inner shell 22 and the molding head 1 are misaligned circumferentially, so that the third end 221 avoids the aforementioned position (locked onto the molding head 1). After the first end 211 is connected to the molding head 1, a connection relationship is established between the first end 211 and the molding head 1, which restricts the rotation of the molding head 1. The third end 221 cannot rotate circumferentially to reset, and cannot detach from the molding head 1 in its original position, thereby fixing the inner shell 22 onto the molding head 1, realizing the assembly operation of the molding head 1 and the handle 2.

[0042] With this configuration, both the outer shell 21 and the inner shell 22 are connected to the molding head 1, and the outer shell 21 and the inner shell 22 are also fixedly connected by a connector. The outer shell 21 and the inner shell 22 together restrict the rotation of the molding head 1 and limit each other's movement, resulting in good reliability after the handle 2 is assembled with the molding head 1. In addition, the inner shell 22 snaps into the molding head 1, providing a relatively simple connection structure. Users do not need to turn it many times, making the assembly operation of the molding head 1 and the handle 2 convenient.

[0043] In some embodiments, as shown in Figures 3 to 6, one of the molding head 1 and the inner shell 22 has an insertion interface 31 and a limiting groove 32, and the other of the molding head 1 and the inner shell 22 has a protrusion 33. The molding head 1 can have the insertion interface 31 and the limiting groove 32, and the inner shell 22 can have the protrusion 33; alternatively, the molding head 1 can have the protrusion 33, and the inner shell 22 can have the insertion interface 31 and the limiting groove 32. For ease of understanding, the example of the molding head 1 having the insertion interface 31 and the limiting groove 32, and the inner shell 22 having the protrusion 33, will be explained. The insertion interface 31 extends axially and penetrates a portion of the end wall of the molding head 1 in the axial direction. The limiting groove 32 communicates with the insertion interface 31 and extends circumferentially, i.e., the limiting groove 32 is formed in the circumferential direction and is at least arc-shaped. The protrusion 33 is inserted axially into the insertion interface 31 and rotates circumferentially into the limiting groove 32. The protrusion 33 moves axially along the insertion interface 31. After rotation, the protrusion 33 enters the limiting groove 32 through the position where the insertion interface 31 connects with the limiting groove 32. A relative positional change occurs between the protrusion 33 and the insertion interface 31, and the protrusion 33 and the insertion interface 31 are misaligned in the circumferential direction until the protrusion 33 is engaged in the limiting groove 32. At this time, the protrusion 33 cannot detach from the molding head 1 along the insertion interface 31, so that the inner shell 22 is fixed on the molding head 1, and the outer shell 21 is fixed to the inner shell 22 through the connector, thus fixing it to the molding head 1 through the inner shell 22. Thus, the assembly operation of the handle 2 is completed.

[0044] Optionally, the connector is configured as a threaded fastener, which axially fixes the inner shell 22 and the outer shell 21. Due to the adjustability of the threaded connection, the connector axially tightens the inner shell 22 and the outer shell 21, causing the protrusion 33 in the limiting groove 32 to axially abut against the end wall forming the limiting groove 32, increasing the friction between the protrusion 33 and the end wall forming the limiting groove 32.

[0045] In some embodiments, as shown in FIG3, the handle 2 further includes a bottom cover 28, which is axially snapped onto the housing 21. Specifically, the second end 212 of the housing 21 is typically configured as an open structure to facilitate assembly or allow the power cord to pass through. Therefore, by providing the bottom cover 28, the opening of the second end 212 can be covered to improve the integrity of the overall structure.

[0046] In some embodiments, as shown in Figures 3 and 4, the bottom cover 28 is a rotating body, meaning its cross-sectional shape is circular. The cross-sectional direction of the rotating body is radial. The bottom cover 28 has a radially protruding buckle, and the outer shell 21 has corresponding latching positions adapted to the buckle. By inserting the buckle into the latching position, a fixed connection between the bottom cover 28 and the outer shell 21 can be achieved. This design is simple and easy to assemble and disassemble.

[0047] In some embodiments, as shown in FIG7, the molding head 1 is further provided with a first connector 11, and the handle 2 is further provided with a second connector 23. The first connector 11 and the second connector 23 are connected to keep the molding head 1 and the handle 2 connected. Specifically, after the first connector 11 and the second connector 23 are connected, they generate a mutual connecting force. This force keeps the first connector 11 and the second connector 23 connected, thereby making the molding head 1 and the handle 2 maintain a relatively stable connection. This reduces the possibility of the molding head 1 and the handle 2 separating due to accidental contact or vibration after they are connected, and improves the user experience.

[0048] Specifically, the first connector 11 and the second connector 23 can be elastic self-locking structures or magnetic adsorption structures. The embodiments of this application do not limit the specific structure of the first connector 11 and the second connector 23, as long as the first connector 11 and the second connector 23 are connected after the handle 2 is inserted into the molding head 1.

[0049] In some embodiments, as shown in FIG7, at least one of the first connector 11 and the second connector 23 is a magnetic element and is magnetically connected to the other of the first connector 11 and the second connector 23. Specifically, only the first connector 11 may be a magnetic element, and the second connector 23 may be a ferromagnetic metal or alloy element; only the second connector 23 may be a magnetic element, and the first connector 11 may be a ferromagnetic metal or alloy element; or both the first connector 11 and the second connector 23 may be magnetic elements, in which case the magnetic properties of the first connector 11 and the second connector 23 are opposite. Regardless of which of the aforementioned embodiments the first connector 11 and the second connector 23 are configured in, as long as the first connector 11 and the second connector 23 are magnetically attracted after the molding head 1 is inserted into the handle 2, an attractive force is formed to keep the molding head 1 and the handle 2 connected.

[0050] Typically, a molding head 1 is connected to the handle 2, while other molding heads 1 are independent of the handle 2. The first connector 11 located in the molding head 1 easily attracts fine particles or ferromagnetic components. By making the first connector 11 a ferromagnetic component, it is possible that the first connector 11 itself does not generate magnetic attraction force, thus reducing the possibility of the first connector 11 accidentally attracting other components. On the other hand, the second connector 23 located on the handle 2 is less likely to come into contact with the external environment, making it less likely to attract fine particles or ferromagnetic components from the external environment. Therefore, the second connector 23 can be made a magnetic component.

[0051] In some embodiments, as shown in FIG7, a first slot 13 is provided on the molding head 1. The contour of the first slot 13 is adapted to the contour of the first connector 11, and the first connector 11 is installed in the first slot 13. The first slot 13 forms the installation reference of the first connector 11. By snapping the first connector 11 into the first slot 13, the first connector 11 can be stably and accurately installed, which is beneficial to alignment with the second connector 23.

[0052] In some embodiments, as shown in FIG7, a second slot 25 is provided on the handle 2. The contour of the second slot 25 is adapted to the contour of the second connector 23, and the second connector 23 is installed in the second slot 25. The second slot 25 forms the installation reference for the second connector 23. By engaging the second connector 23 in the second slot 25, the second connector 23 can be stably and accurately installed. This allows the first connector 11 and the second connector 23 to be accurately and stably connected, facilitating smooth insertion of the handle 2 and the molding head 1.

[0053] In some possible implementations, a first slot 13 can be formed on the molding head 1, while a second slot 25 can be formed on the handle 2. With this configuration, the first slot 13 can be used to engage the first connector 11, defining the position of the first connector 11, while the second slot 25 can be used to engage the second connector 23, defining the position of the second connector 23.

[0054] In some embodiments, as shown in FIG7, the molding head 1 is further provided with a first electrical connector 12, and the handle 2 is further provided with a second electrical connector 24. When the molding head 1 and the handle 2 are connected, the first electrical connector 12 and the second electrical connector 24 are electrically connected. Specifically, the number of the first electrical connector 12 and the second electrical connector 24 may correspond, such as one first electrical connector 12 corresponding to one second electrical connector 24; or the shapes of the first electrical connector 12 and the second electrical connector 24 may correspond, such as the first electrical connector 12 having a circular insertion hole, and the second electrical connector 24 being a columnar body extending axially and inserted into the circular insertion hole, thereby realizing the electrical connection between the first electrical connector 12 and the second electrical connector 24, and thus enabling the supply of electrical energy or transmission of control electrical signals to the molding head 1 through the handle 2 during operation.

[0055] In some embodiments, as shown in FIG7, at least one of the first electrical connector 12 and the second electrical connector 24 is configured as an elastic telescopic member. When the molding head 1 is connected to the handle 2, the elastic telescopic member is in a compressed state and abuts against the other of the first electrical connector 12 and the second electrical connector 24 axially. Specifically, only the first electrical connector 12 may be configured as an elastic telescopic member, only the second electrical connector 24 may be configured as an elastic telescopic member, or both the first electrical connector 12 and the second electrical connector 24 may be configured as elastic telescopic members.

[0056] In some possible implementations, both the first electrical connector 12 and the second electrical connector 24 can be configured as flexible circuit boards, and upon contact, directly form an energized circuit that electrically connects the molding head 1 and the handle 2.

[0057] To facilitate understanding, let's take the example of the first electrical connector 12 being configured as an elastic telescopic component: When the molding head 1 and the handle 2 are axially connected, the first electrical connector 12 abuts against the second electrical connector 24 in the axial direction and is in a compressed state. The first electrical connector 12 has an elastic force to recover its deformation, and by pressing against the second electrical connector 24, the first electrical connector 12 and the second electrical connector 24 maintain a relatively stable connection, improving the reliability of the electrical connection between the molding head 1 and the handle 2.

[0058] In some embodiments, as shown in Figures 5 and 6, the first connecting structure 10 is either a slot or a plug, and the second connecting structure 20 is the other slot or plug. The plug is inserted into the slot, thus achieving a detachable connection between the molding head 1 and the handle 2. Specifically, the molding head 1 and the handle 2 are detachably connected via an axial insertion / removal method. The outer contours of the slot and the plug are designed to match, with the slot extending a certain depth in the axial direction and the plug extending a certain length in the axial direction. Thus, the plug is inserted into the slot to achieve connection, resulting in a simple structure, convenient connection, and good reliability.

[0059] In some embodiments, the cross-sections of the slot and the connector along the axial direction can be set to a D-shape or a polygonal structure, which can guide the connection direction when the molding head 1 and the handle 2 are connected, and can prevent relative rotation between the molding head 1 and the handle 2, thereby improving the reliability of the connection between the molding head 1 and the handle 2.

[0060] In some embodiments, as shown in Figures 3 and 8, the control component 26 includes at least a circuit board 261, a controller 263, a control switch, and power control components. Under the control provided by the control component 26, the connected styling head 1 can be turned on or off normally. This includes providing electrical energy to the styling head 1, controlling the heating function of the styling head 1, and selecting the hair styling mode, thus enriching the product's functionality.

[0061] In some embodiments, as shown in FIG8, the inner shell 22 includes an upper cover 223 and a lower cover 224, which are detachably connected. Specifically, at least one of the upper cover 223 and the lower cover 224 has an internal recess to form a receiving space 220 when combined with the upper cover 223 and the lower cover 224. At least a portion of the control component 26 can be installed and fixed within the receiving space 220, and the control component 26 is detachably connected to both the upper cover 223 and the lower cover 224. The assembly operation of the control component 26 can be completed during the assembly of the upper cover 223 and the lower cover 224. When the inner shell 22 is configured with an upper cover 223 and a lower cover 224, the end of the upper cover 223 and the lower cover 224 facing the molding head 1 constitutes a third end 221, and the end of the upper cover 223 and the lower cover 224 facing the bottom cover 28 constitutes a fourth end 222.

[0062] Specifically, as shown in Figure 8, at least one of the upper cover 223 and the lower cover 224 is provided with a support member 225 for supporting the control component 26, and at least the circuit board 261 of the control component 26 abuts against the support member 225. Thus, by placing the circuit board 261 on the support member 225 and then fastening the upper cover 223 onto the lower cover 224, the assembly operation of the circuit board 261 can be realized. In this way, the assembly and disassembly of the circuit board 261 can be carried out simultaneously during the assembly and disassembly of the upper cover 223 and the lower cover 224, reducing both the assembly and disassembly difficulty of the circuit board 261, demonstrating a clever design.

[0063] In some embodiments, as shown in Figures 3 and 9, the styling head 1 is configured to include a first functional head 1a, which includes a body 11a, a curling component 12a, and a detection component 13a. The body 11a forms a curling cavity 111a, which provides space for mounting and for winding hair. At least a portion of the curling component 12a and the detection component 13a are mounted in the curling cavity 111a.

[0064] The hair curling component 12a generates heat and rotates relative to the main body 11a to wrap around and style the hair into curls. Specifically, the hair curling component 12a can rotate relative to the main body 11a as a whole. For example, the hair curling component 12a may include a heating rod 121a that rotates relative to the main body 11a. The heating rod 121a 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 121a is driven to rotate, the hair is wrapped around and heated, thus creating curls.

[0065] Of course, some parts of the hair curling component 12a may also rotate relative to the main body 11a. This application embodiment does not impose further limitations on the implementation of the hair curling component 12a, as long as the hair curling component 12a can achieve hair wrapping and hair perming.

[0066] As shown in Figure 9, the main body 11a has multiple hair-receiving slots 112a spaced apart from each other, and each hair-receiving slot 112a is connected to the hair-curling cavity 111a, that is, each hair-receiving slot 112a penetrates the side wall of the main body 11a. The main body 11a may have only two hair-receiving slots 112a or more hair-receiving slots 112a, and hair can be placed in any one of the hair-receiving slots 112a.

[0067] The detection component 13a is used to detect whether any hair-containing slot 112a contains hair, and generates an presence signal when any hair-containing slot 112a contains hair. The control component 26 is used to control the hair-curling component 12a to rotate and wrap the hair according to the presence signal, and only when hair is contained in one hair-containing slot 112a.

[0068] Specifically, when hair is placed in any of the hair-receiving slots 112a, the detection component 13a can determine that the hair-receiving slot 112a is in a hair-receiving state by sensing changes in light, etc., thereby generating an presence signal and transmitting it to the control component 26. The control component 26 controls the curling component 12a to rotate according to the presence signal to achieve the curling operation. When no hair enters the hair-receiving slot 112a, the detection component 13a is not triggered, and at this time the control component 26 (see Figure 3) can control the curling component 12a not to perform the curling operation. When hair is placed in two or more hair-receiving slots 112a, the control component 26 still controls the curling component 12a not to perform the curling operation, reducing the possibility of scalp pulling and ensuring high safety.

[0069] In some embodiments, as shown in Figures 9 and 10, the hair curling assembly 12a includes a heating rod 121a and hair claws 122a installed within a hair curling cavity 111a. The heating rod 121a is fixedly installed within the hair curling cavity 111a and is used to generate heat to heat the hair. The hair claws 122a are sleeved outside the heating rod 121a. The control assembly 26 can drive the hair curling assembly 12a to rotate around the heating rod 121a according to an in-situ signal to achieve hair curling.

[0070] In this embodiment, the first functional head 1a is used as a curling head. The aforementioned "shaping parameters" can be the extension length of the heating rod 121a, the diameter of the heating rod 121a, or the size of the gap between the heating rod 121a and the body 11a. By changing the first functional head 1a, the extension length of the heating rod 121a can be changed, allowing hair of different lengths to be wrapped around the heating rod 121a, thus accommodating both long and short hair; by changing the diameter of the heating rod 121a, curls of different diameters can be created; and by changing the size of the gap between the heating rod 121a and the body 11a, it can accommodate multiple users with hair of different thicknesses.

[0071] Specifically, the curling component 12a rotates in different directions depending on the hair's position within the different hair-receiving slots 112a. The detection component 13a automatically identifies which specific slot within each hair-receiving slot 112a the hair to be processed is in and generates different rotation signals accordingly. The curling component 12a then automatically rotates in the corresponding direction based on these signals. Throughout the entire process, the rotation of the curling component 12a is performed automatically, eliminating the need for manual operation of multiple buttons, thus reducing the user's operational difficulty and improving curling efficiency.

[0072] For example, the main body 11a has two hair-receiving slots 112a, which are respectively the first hair-receiving slot and the second hair-receiving slot. The detection component 13a is used to sense whether hair is in the first or second hair-receiving slot. When hair is sensed in the first hair-receiving slot, a first rotation signal is generated; when hair is sensed in the second hair-receiving slot, a second rotation signal is generated. The curling component 12a 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. In this way, the curling component 12a can automatically switch the rotation direction, eliminating the need for the user to manually switch the rotation direction of the curling component 12a using multiple buttons, reducing the possibility of user misjudgment and improving the accuracy of curling.

[0073] In the schematic diagram of Figure 9, the hair-receiving groove 112a on the left is regarded as the first hair-receiving groove, and correspondingly, the hair-receiving groove 112a on the right is regarded as the second hair-receiving groove. However, this is only an exemplary illustration and does not limit the specific positions of the first and second hair-receiving grooves. That is to say, either of the two hair-receiving grooves 112a can be regarded as the first hair-receiving groove, and the other can be regarded as the second hair-receiving groove.

[0074] In some embodiments, as shown in Figures 9 and 11, the curling assembly 12a further includes a protrusion 123a. The protrusion 123a is disposed on the side of the hair claw 122a facing the heating rod 121a. The protrusion 123a is configured to reduce the gap between the hair and the surface of the heating rod 121a, thereby wrapping the hair around the heating rod 121a. Specifically, as the hair claw 122a rotates around the heating rod 121a, the protrusion 123a rotates synchronously and squeezes the hair located between the hair claw 122a and the heating rod 121a, thereby pressing the hair tightly against the heating rod 121a. Furthermore, as the hair claw 122a rotates, the protrusion 123a can repeatedly squeeze the hair, effectively preventing the hair from loosening or detaching from the heating rod 121a, ensuring the hair adheres tightly to the heating rod 121a. Moreover, the protrusion 123a can also distribute the hair through squeezing, making the hair evenly distributed on the heating rod 121a, resulting in more thorough heating and a better heating effect.

[0075] Specifically, the protrusion 123a can be integrally formed with the hair claw 122a without separate assembly, simplifying the production process. Alternatively, the protrusion 123a can be separately set from the hair claw 122a and assembled using adhesive or detachable connections. Various implementation schemes exist for the arrangement, shape, number, and relative position of the protrusion 123a. This application does not impose further limitations on the implementation of the protrusion 123a, as long as it effectively presses the hair firmly against the heating rod 121a.

[0076] In some embodiments, the cross-sectional shape of the protrusion 123a is "wavy" or "serrated" along the axis perpendicular to the rotation of the hair claw 122a. When the shape of the protrusion 123a is designed to be "wavy" or "serrated", it is equivalent to forming multiple mutually spaced protrusions on the side of the protrusion 123a facing the heating rod 121a. Each protrusion squeezes the hair, increasing the squeezing area, thereby further optimizing the effect of squeezing the hair.

[0077] In some embodiments, as shown in FIG10, the first functional head 1a further includes a magnetic element 14a, which is disposed on the hair curling component 12a and rotates relative to the detection component 13a under the drive of the hair curling component 12a. Specifically, the magnetic element 14a can be snapped onto the hair claw 122a, as long as the magnetic element 14a can be fixed on the hair claw 122a. For example, a slot can be provided on the side of the claw 122a adjacent to the handle 2, and a gear ring (i.e., driven gear 272) can be engaged in the slot. The claw 122a has a sliding groove 1221a on the inner side of the slot and / or the outer side of the gear ring, which can accommodate the magnetic component 14a. First, the magnetic component 14a is installed into the sliding groove 1221a, and then the gear ring is engaged into the base of the claw 122a. At this time, the gear ring (i.e., driven gear 2722) abuts against the bottom of the magnetic component 14a, thereby limiting the magnetic component 14a in the sliding groove 1221a, and simultaneously realizing the fixed installation of the magnetic component 14a.

[0078] The detection component 13a 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.

[0079] The detection component 13a is electrically connected to the controller in the control component 26. The detection component 13a may include a Hall element, a signal amplification circuit, a regulated power supply, and an output interface. The Hall element can respond to a magnetic field and generate a Hall voltage. The signal amplification circuit can amplify the signal to a level that can be recognized by the controller. 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.

[0080] As shown in Figure 10, the detection component 13a senses and generates a position signal with the magnetic component 14a. The claw 122a resets to its initial position based on the position signal, which is the position of the claw 122a before it is driven. The magnetic component 14a can rotate with the claw 122a. The detection component 13a remains stationary relative to the magnetic component 14a and the claw 122a, that is, the detection component 13a is in a fixed position relative to the magnetic component 14a and the claw 122a. Thus, when the claw 122a drives the magnetic component 14a to rotate, the position of the magnetic component 14a relative to the detection component 13a changes. The detection component 13a 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 122a.

[0081] As shown in Figure 10, the initial position can be a fixed, safe position that the claw 122a is in before it is driven. After receiving the position signal, the controller can compare the position signal with the initial position to determine whether the claw 122a needs to be reset. If a reset is required, the controller controls the claw 122a to rotate. During this process, the detection component 13a can continuously detect the position of the claw 122a based on the position change of the magnetic component 14a and feed it back to the controller. The controller thus ensures that the claw 122a is accurately reset.

[0082] At least a portion of the magnetic component 14a is located within the circumference of the detection component 13a, so that the detection component 13a can accurately sense the positional changes of the magnetic component 14a.

[0083] In this embodiment, the position of the claw 122a is detected by the cooperation of the detection component 13a and the magnetic component 14a. The claw 122a returns to its initial position based on the position signal. Thus, the claw 122a automatically returns to a fixed, safe position after each use, eliminating the need for manual rotation or button activation. This reduces the risk of improper user operation and improves the user experience. Consequently, the first functional head 1a offers high safety and convenience.

[0084] In some embodiments, as shown in Figures 3 and 12, the control component 26 includes a motor 262 and a controller 263. The motor 262 is driven by the claw 122a to drive the claw 122a to rotate. The controller 263 is electrically connected to the detection component 13a (see Figure 10) and the motor 262 to receive an in-situ signal and control the motor 262. A transmission component 27 is connected between the output shaft of the motor 262 and the claw 122a. The transmission component 27 has at least a first transmission pair 217 and a second transmission pair 272. The power of the motor 262 is output to the claw 122a sequentially via the first transmission pair 217 and the second transmission pair 272, and the transmission ratio of the first transmission pair 217 and the second transmission pair 272 is greater than 1.

[0085] In the transmission direction along the output shaft of motor 262 to claw 122a, the input speed is greater than the output speed. With a constant power, torque is negatively correlated with speed; therefore, both the first transmission pair 217 and the second transmission pair 272 output low speed and high torque. Specifically, the output speed of the first transmission pair 217 is less than the input speed, and the output torque of the first transmission pair 217 is greater than the input torque. When there is no power loss between the output shaft of motor 262 and the first transmission pair 217, the input speed of the first transmission pair 217 is equal to the output shaft speed of motor 262, and the input torque of the first transmission pair 217 is equal to the output shaft torque of motor 262. Similarly, the output speed of the second transmission pair 272 is less than the output speed of the first transmission pair 217, and the output torque of the second transmission pair 272 is greater than the input torque. When there is no power loss between the second transmission pair 272 and claw 122a, the output speed of the second transmission pair 272 is equal to the speed of claw 122a, and the output torque of the second transmission pair 272 is equal to the torque of claw 122a. Simply put, both the first transmission pair 217 and the second transmission pair 272 are "reduction and torque increase" type transmissions. The first transmission pair 217 and the second transmission pair 272 provide transmission buffer between the output shaft of the motor 262 and the claw 122a, so that the speed at the output shaft of the motor 262 decreases step by step and the torque increases step by step, reducing the possibility of transmission jamming and enabling the transmission of larger torque to transmit power more efficiently.

[0086] As shown in Figure 12, the motor 262 is connected to a reduction gearbox 2711, the reduction gearbox 2711 is connected to a drive gear 2721, and the claw 122a is connected to a driven gear. The drive gear 2721 and the driven gear 2722 mesh. The reduction gearbox 2711 forms a first transmission pair 217, and the drive gear 2721 and the driven gear 2722 form a second transmission pair 272. The driven gear 2722 can be a gear ring to form an inner and outer meshing structure with the drive gear 2721. The reduction gearbox 2711 can be controlled by software to adjust the transmission speed ratio from the motor 262 to the claw 122a.

[0087] Of course, at least one planetary gear can also be provided between the driving gear 2721 and the driven gear 2722. In this case, the driving gear 2721, the driven gear 2722, and the planetary gear form a planetary gear train, with the driving gear 2721 being the sun gear in the planetary gear train. The reduction gearbox 2711 forms the first transmission pair 217, the driving gear 2721 and the planetary gear form the second transmission pair 272, and the planetary gear and the driving gear 2721 form the third transmission pair, thus forming a three-stage reduction on the transmission path from the motor 262 to the claw 122a. Alternatively, the reduction gearbox 2711 can be omitted, and only the planetary gear train can be provided to form two transmission pairs (as shown in Figure 6), thus forming a two-stage transmission on the transmission path from the motor 262 to the claw 122a.

[0088] In some embodiments, as shown in FIG13, a mounting groove 226 is provided on the inner side of the inner shell 22, and the motor 262 is fixed in the mounting groove 226 along the axial direction. The motor 262 is a columnar member, and the shape of the mounting groove 226 is adapted to the outline shape of the motor 262. After the motor 262 is installed in the mounting groove 226, at least a portion of the motor 262 is engaged with the groove wall of the mounting groove 226, and both ends of the motor 262 abut against the end walls of the mounting groove 226 respectively. The end walls of the mounting groove 226 restrict the axial degree of freedom of the motor 262. The relative position of the motor 262 is constrained by the mounting groove 226, resulting in good stability after installation.

[0089] In some embodiments, as shown in FIG13, a clamping cover 227 is also connected to the inner shell 22, and the motor 262 is fixed between the clamping cover 227 and the inner shell 22. Specifically, the clamping cover 227 is detachably connected to the inner shell 22 by screw-like fasteners. By fixing the clamping cover 227, the motor 262 is radially pressed against the groove wall of the mounting groove 226, improving the stability of the motor 262 installation. Furthermore, a positioning groove 2271 can be provided on the side of the clamping cover 227 facing the motor 262. The positioning groove 2271 is adapted to the contour shape of the motor 262. The motor 262 is installed in the positioning groove 2271, so that the positioning groove 2271 can press against the motor 262 in the circumferential direction. That is, the positioning groove 2271 can cover the motor 262, and a surface contact is formed between the clamping cover 227 and the motor 262. The contact area is large, which can further press the motor 262.

[0090] In some embodiments, as shown in Figures 3 and 4, at least one of the motor 262 and the clamping cover 227 is provided with a flexible element 228, which is sandwiched between the motor 262 and the clamping cover 227. It is understood that the flexible element 228 is elastic and capable of deformation. The clamping cover 227 presses against the motor 262, causing the flexible element 228 to compress and deform, increasing the friction between the clamping cover 227 and the surface of the motor 262, thus allowing the motor 262 to be more stably assembled between the mounting groove 226 and the clamping cover 227. In addition, the flexible element 228 can also dampen vibrations in the motor 262 and reduce the noise generated by the motor 262 during operation.

[0091] In some embodiments, as shown in Figures 3 and 4, the first functional head 1a is used to automatically wind hair, achieving hair curling. Therefore, the hair claw 122a is driven to rotate by the motor 262, thereby enabling the hair claw 122a to rotate and automatically wrap the hair around the heating rod 121a. To achieve transmission between the motor 262 and the hair claw 122a, a first transmission structure 2621 is connected to the output shaft of the motor 262, and a second transmission structure 1222a is connected to the hair claw 122a. When the first functional head 1a is connected to the handle 2, the first transmission structure 2621 and the second transmission structure 1222a are connected in a transmission manner. Thus, with the mutual connection of the first transmission structure 2621 and the second transmission structure 1222a, a driving force can be transmitted, enabling the hair claw 122a to rotate around the heating rod 121a, thereby achieving the winding of the hair around the heating rod 121a.

[0092] Specifically, the first transmission structure 2621 can be either a shaft hole or a connector, and the second transmission structure 1222a can be the other one. The connector can be inserted into the shaft hole, thus enabling the transmission connection between the output shaft of the motor 262 and the actuator 122a for torque transmission. To increase the stability of the torque transmission, the axial cross-sectional shapes of the shaft hole and the connector can be set to be mutually matching polygons, such as quadrilaterals, pentagons, hexagons, etc. This prevents relative slippage when the connector is inserted into the shaft hole, improving the reliability and efficiency of the transmission.

[0093] In some embodiments, as shown in Figures 10 and 14, the heating rod 121a includes a heating element 1211a, a heat conductor 1212a, and a mounting bracket 1213a. The heating element 1211a generates heat to heat-treat the hair after being energized, and the heat conductor 1212a conducts the heat generated by the heating element 1211a. A cavity 1210a is formed inside the heat conductor 1212a, and a receiving groove 1214a for accommodating hair is recessed in the outer wall of the heat conductor 1212a, extending axially to both ends of the heat conductor 1212a. The mounting bracket 1213a is connected to the inner wall of the heat conductor 1212a. The mounting bracket 1213a has at least one mounting cavity 1215a for inserting the heating element 1211a, or a mounting cavity 1215a for inserting the heating element 1211a is formed between the mounting bracket 1213a and the inner wall of the heat conductor 1212a. Thus, by inserting the heating element 1211a into the mounting cavity 1215a, the mounting position of the heating element 1211a can be reliably installed simply by defining the mounting position using the structure of the mounting bracket 1213a, without the need for adhesive bonding, screw connections, or other methods of fixation. This effectively simplifies the installation operation of the heating element 1211a, making installation convenient and improving assembly efficiency.

[0094] Specifically, the heating element 1211a is installed into the mounting cavity 1215a with an interference fit, or the heating element 1211a is connected to the mounting bracket 1213a using a snap-fit ​​structure. After installation, the heating element 1211a has good stability and does not require operations such as gluing or screw fixing, which greatly improves the ease of installation of the heating element 1211a.

[0095] The receiving groove 1214a formed on the heat conductor 1212a typically serves to guide hair into the curling iron and adjust the hair's position. The specific shape of the receiving groove 1214a can be flexibly designed according to user preferences and other factors. For example, along the axis perpendicular to the heat conductor 1212a, the cross-section of the receiving groove 1214a is U-shaped. This shape of receiving groove 1214a is easy to process, has no sharp edges, and is aesthetically pleasing. Of course, the receiving groove 1214a can also be set to other shapes; this embodiment does not impose further limitations on this.

[0096] In some embodiments, the mounting bracket 1213a extends from one end of the heat conductor 1212a to the opposite end along the axial direction of the heat conductor 1212a. That is, the mounting bracket 1213a is a continuous structure, which not only reliably supports the heating element 1211a but also guides its installation. Alternatively, the mounting bracket 1213a can be positioned only at opposite ends of the heat conductor 1212a, with both ends of the heating element 1211a connected to two mounting brackets 1213a respectively. The key is to ensure that the heating element 1211a can be installed within the mounting cavity 1215a and reliably maintain contact with the heat conductor 1212a.

[0097] In some embodiments, as shown in FIG10, the hair curling assembly 12a further includes an end cap assembly 124a, the end cap assembly 33a being disposed at the free end of the heat conductor 1212a, and the end cap assembly 124a having a hollow cavity 1241a for heat insulation.

[0098] The end cap assembly 124a is located on the open side of the curling cavity 111a. During use, the end cap assembly 124a isolates the heat conductor 1212a from the user's scalp, preventing direct contact between the heat conductor 1212a and the user's scalp. Furthermore, the hollow cavity 1241a of the end cap assembly 124a also isolates the heat generated by the heating rod 121a, resulting in a lower temperature at the end (upper end) of the end cap assembly 124a away from the heat conductor 1212a. This reduces the impact of the heat generated by the heating rod 121a on the user's scalp, thereby improving the user experience.

[0099] The end cap assembly 124a can be made of a material with heat insulation and temperature resistance properties, thereby further improving the heat insulation and temperature resistance of the end cap assembly 124a.

[0100] The connection between the end cap assembly 124a and the heat conductor 1212a can be achieved by screw fasteners, adhesive bonding, or by having snap-fit ​​structures that can be fitted together, thereby allowing the end cap assembly 124a and the heat conductor 1212a to be snapped together and fixed.

[0101] In some embodiments, as shown in FIG10, a rotation gap 15a is formed between the hair claw 122a and the heat conductor 1212a, so that the hair claw 122a can rotate around the heat conductor 1212a without motion interference. By providing a filler 16a within the rotation gap 15a, that is, by providing a certain filling effect to the rotation gap 15a, the radial dimension of the rotation gap 15a along the heat conductor 1212a can be reduced, even reduced to approximately zero. This helps to reduce the risk of hair getting caught in the rotation gap 15a. During the rotation and hair wrapping process, the hair claw 122a will basically not cause hair to get stuck in the rotation gap 15a, thereby reducing safety hazards, improving user discomfort, and enhancing the overall user experience of the product.

[0102] The specific type of filler 16a is not limited. In one embodiment, filler 16a is a bearing. The bearing may be, for example, a rolling bearing, a sliding bearing, or a spherical bearing, etc., and is not limited thereto.

[0103] In some embodiments, as shown in Figures 1 and 15, the shaping head 1 further includes a second functional head 1b, which is used to straighten hair so that the hair remains straight for a preset time period. Specifically, the second functional head 1b includes a housing 11b, a straightening component 12b, and a resetting component 13b. The housing 11b has a hollow interior forming a receiving cavity 110b for accommodating and mounting other parts. The shape of the housing 11b can be designed according to requirements such as aesthetics, practicality, and ease of processing. In this embodiment, the housing 11b is exemplified as being cylindrical, with a hollow interior forming the receiving cavity 110b. Furthermore, at least one end of the housing 11b is provided with an opening communicating with the receiving cavity 110b, through which other parts are mounted into the receiving cavity 110b.

[0104] Specifically, as shown in Figure 15, the hair straightening component 12b is used for hair styling. The hair straightening component 12b is disposed within the receiving cavity 110b, and at least two are arranged opposite each other. At least one of the two hair straightening components 12b is movable to reciprocate relative to the housing 11b. A hair-holding gap 14b is provided between the two oppositely arranged hair straightening components 12b. Hair is inserted into the hair-holding gap 14b, and the two oppositely arranged hair straightening components 12b jointly clamp the hair, styling it to a straight state.

[0105] In this embodiment, under normal conditions, the two opposing straightening components 12b tend to move closer together, allowing them to maintain contact or have a certain width of hair-holding gap 14b. The width of this gap 14b does not affect the clamping force formed by the two straightening components 12b when hair is inserted between them, thus clamping the hair. By setting the two opposing straightening components 12b in a clamping state, the hair inserted between them can be automatically clamped, and the space for accommodating the hair can be automatically adjusted without manual operation. Compared to a method where one end is open and requires manual closing, this second functional head 1b automatically clamps the hair simply by inserting it, making operation much more convenient.

[0106] In some embodiments, as shown in FIG15, a reset member 13b is provided in the receiving cavity 110b. The reset member 13b can generate a driving force to drive the two opposing straightening components 12b to maintain the hair clamping state. The reset member 13b is disposed in the receiving cavity 110b, and can be directly connected to the housing 11b; or it can be close to the housing 11b but with a small gap and not in direct contact. After hair is inserted between the two straightening components 12b, the straightening components 12b are squeezed to move and come into contact with the reset member 13b, thereby causing the reset member 13b to be subjected to force, which pushes the straightening components 12b to move to the initial state, thereby enabling the two opposing straightening components 12b to be maintained in the clamping state.

[0107] Specifically, the reset member 13b can generate a driving force, thereby driving the straightening component 12b to move and remain in a clamping state. To reliably maintain the clamping state of the two opposing straightening components 12b, a reset member 13b can be provided in at least one of the two opposing straightening components 12b. Under the driving force generated by the reset member 13b, at least one straightening component 12b can move closer to the other straightening component 12b, achieving the clamping function. Alternatively, each of the two opposing straightening components 12b can be provided with a reset member 13b, and the reset members 13b can be connected to their respective straightening components 12b. In this way, the movement between the two straightening components 12b can be driven by the corresponding reset members 13b, 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 is clamped.

[0108] The reset member 13b can be a mechanism that provides telescopic movement after being energized, such as a motor screw mechanism or a telescopic rod. In this case, the movement of the hair straightening assembly 12b can be automatically controlled by detecting whether hair is inserted. In this embodiment, the reset member 13b 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 13b in a compressed state under normal conditions, thereby generating a restoring deformation force. Under this force, the connected hair straightening assembly 12b moves in the direction of the other hair straightening assembly 12b, that is, the two hair straightening assemblies 12b remain close to each other under normal conditions, forming a clamping state.

[0109] In some embodiments, as shown in Figures 15 and 16, a notch 111b is provided on the housing 11b to allow hair to be inserted between the two straightening components 12b. Specifically, the notch 111b is formed on the side wall of the housing 11b, allowing hair to be inserted through the notch 111b into the hair-accommodating gap 14b between the two opposing straightening components 12b and held therein. The notch 111b can be positioned opposite the gap formed by the relative opening between the two straightening components 12b, facilitating direct insertion of hair. Of course, it can also be positioned elsewhere, as long as it allows hair to be inserted. The opening at one end of the housing 11b can also be flared to guide hair into the space between the two straightening components 12b.

[0110] In some embodiments, as shown in FIG15, since the hair straightening component 12b generates heat after being powered on, this heat will be transferred to the housing 11b after prolonged use, causing the housing 11b to heat up and affecting the user's grip on the housing 11b. Therefore, in this embodiment, a heat insulation component 15b is provided between the housing 11b and the hair straightening component 12b. This heat insulation component 15b is at least used to block the heat from the hair straightening component 12b from being transferred to the housing 11b. That is, the heat generated by the hair straightening component 12b is blocked by the heat insulation component 15b and will not be directly transferred to the housing 11b. Instead, the heat generated by the hair straightening component 12b must first be transferred to the heat insulation component 15b before it can be transferred to the housing 11b. This reduces the temperature on the housing 11b, effectively preventing high temperatures from affecting the user's grip on the housing 11b or causing safety hazards due to excessive temperature. This significantly improves the comfort and safety of operating the second function head 1b.

[0111] As shown in Figure 15, a receiving groove 152b can be provided on the heat insulation component 15b, one end of the reset component 13b is fixed in the receiving groove 152b, and the other end of the reset component 13b is connected to the hair straightening assembly 12b. In this way, the installation position of the reset component 13b can be limited by the receiving groove 152b, so that the installation position of the reset component 13b can be kept stable and not deviated, and the movement of the hair straightening assembly 12b can be reliably realized.

[0112] In some embodiments, as shown in FIG15, the hair straightening component 12b is movably disposed within the housing 11b, and can reciprocate towards or away from the heat insulation component 15b within the housing 11b. To improve the heat insulation effect on the housing 11b, a heat insulation gap 150b can be formed between the heat insulation component 15b and the hair straightening component 12b. That is, the heat insulation component 15b and the hair straightening component 12b are not in complete contact, but are separated by a gap. Specifically, even when the two opposing hair straightening components 12b are moved away from each other to their maximum position, the hair straightening component 12b and the heat insulation component 15b are still not in complete direct contact. In this way, the heat on the hair straightening component 12b is mainly transferred to the heat insulation component 15b through the air. Since the air has low heat conduction efficiency, the rate at which the heat insulation component 15b heats up can be further reduced, thereby reducing the efficiency and total amount of heat transferred to the housing 11b, effectively preventing the temperature on the housing 11b from becoming too high.

[0113] In this embodiment, a heat insulation element 15b is provided, and a heat insulation gap 150b is formed by spacing it between the hair straightening component 12b and the heat insulation element 15b. Thus, the second functional head 1b has at least two heat insulation solutions: heat insulation by the heat insulation element 15b and heat insulation gap 150b. This dual heat insulation design prevents the temperature on the housing 11b from becoming excessively high. This ingenious design improves user comfort and safety.

[0114] In some embodiments, as shown in FIG15, to improve the smoothness of the movement of the hair straightening component 12b within the housing 11b, a first guide structure 151b can be provided on the heat insulation component 15b, and a second guide structure 121b can be provided on the hair straightening component 12b. The first guide structure 151b and the second guide structure 121b cooperate to guide the movement of the hair straightening component 12b. In this way, the movement of the hair straightening component 12b within the housing 11b is kept smooth by the guidance of the first guide structure 151b and the second guide structure 121b. Consequently, when hair is inserted, the two opposing hair straightening components 12b can smoothly move away from each other to insert the hair. After the hair is inserted, they can smoothly move closer together to clamp the hair.

[0115] In some embodiments, as shown in Figures 15 and 17, the first guide structure 151b includes a guide post 1511b disposed at one end of the heat insulation member 15b along its length, and the second guide structure 121b includes a guide hole 1211b disposed at one end of the straightening assembly 12b along its length, corresponding to the guide post 1511b. The guide post 1511b passes through the guide hole 1211b. This configuration allows the guide post 1511b to provide guidance in the direction of movement. By passing the guide post 1511b through the guide hole 1211b, the straightening assembly 12b can move along the guide post 1511b, thereby guiding and limiting the movement of the straightening assembly 12b. This configuration has a simple overall structure and good guiding effect.

[0116] In some other embodiments, as shown in Figures 15 and 17, the first guide structure 151b may further include a guide groove 1512b disposed at the other end of the length direction of the heat insulation component 15b, and the second guide structure 121b may further include a guide block 1212b disposed at the other end of the length direction of the straightening assembly 12b corresponding to the guide groove 1512b, with the guide block 1212b slidably disposed within the guide groove 1512b. In this way, the guide block 1212b slides along the guide groove 1512b, which can also effectively guide and limit the movement direction of the straightening assembly 12b. Furthermore, a matching limiting structure, such as a limiting step structure, can be provided between the guide block 1212b and the guide groove 1512b to limit the movement position of the guide block 1212b within the guide groove 1512b, thereby limiting the proximity of the two straightening assemblies 12b.

[0117] In some embodiments, as shown in FIG17, the heat insulation component 15b and / or the hair straightening component 12b are further provided with a limiting member 16b for limiting the movement range of the hair straightening component 12b. Specifically, since the hair straightening component 12b is movably disposed within the housing 11b, when hair is inserted between two opposing hair straightening components 12b, the two hair straightening components 12b are simultaneously squeezed to move in opposite directions. Thus, by providing the limiting member 16b, which can be a limiting plate or limiting post with a preset height, the maximum distance between the two hair straightening components 12b can be limited. Therefore, it not only limits the maximum amount of hair that can be inserted, but also avoids the problem of excessive compression of the hair straightening component 12b due to excessive hair insertion, thus better ensuring the safety of the overall structure. At the same time, limiting the maximum amount of hair inserted can also ensure the hair processing effect, preventing the problem of poor heating effect and poor processing effect due to excessive hair insertion.

[0118] In some embodiments, as shown in Figures 15 and 16, the hair straightening assembly 12b includes a heating element 122b and a fixing shell 123b. The heating element 122b is used to heat the hair to improve the effect of hair styling. The fixing shell 123b is movably disposed within the housing 11b, and the heating element 122b is mounted on the fixing shell 123b and at least partially exposed outside the fixing shell 123b, so that the inserted hair can contact the heating element 122b exposed outside the fixing shell 123b to heat the hair. The heating element 122b can be an object that generates heat when energized, such as an electric heating plate, electric heating wire, or electric plate, and is shaped accordingly according to design requirements. The fixing shell 123b provides support for the mounting position of the heating element 122b. When energized, the heating element 122b heats up and can directly contact the hair for heat treatment. The reset member 13b abuts against the fixed shell 123b (a gap may exist when no force is applied) or is directly connected. The reset member 13b can drive the fixed shell 123b to move, which in turn drives the heating member 122b 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, thus achieving a hair-clamping state at all times.

[0119] The installation method between the heating element 122b and the fixing shell 123b can be by snap-fit ​​or by screw-like fasteners, or by the fixing shell 123b being fitted over part of the heating element 122b. There are various installation methods, as long as the heating element 122b can be reliably fixed and at least a part of the fixed heating element 122b can be exposed outside the fixing shell 123b.

[0120] Specifically, in the case where the hair straightening assembly 12b is configured to include a heating element 122b and a fixing shell 123b, the reset element 13b is disposed between the heat insulation element 15b and the fixing shell 123b, the heat insulation gap 150b is formed between the fixing shell 123b and the heat insulation element 15b, and the second guide structure 121b is disposed on the fixing shell 123b.

[0121] In some embodiments, as shown in Figures 15 and 18, the hair to be processed is typically inserted through the open ends of the two straightening components 12b. Therefore, an anti-clamping gap 17b is provided at least between the fixed housing 123b and the heating element 122b at the end for inserting the hair to prevent hair from getting stuck. That is, the fixed housing 123b and the heating element 122b at the open end are spaced apart, so that even if hair enters the anti-clamping gap 17b, the width of the anti-clamping gap 17b is greater than the thickness of the hair, allowing the hair to smoothly detach within the anti-clamping gap 17b, thus preventing the hair from getting stuck. This effectively avoids the pulling pain caused by the hair being stuck, improving the user's actual comfort.

[0122] In some embodiments, as shown in Figures 15 and 19, the fixing shell 123b includes a first shell 1231b and a second shell 1232b. The first shell 1231b and the second shell 1232b mainly serve as the housing 11b portion, providing mounting support for the heating element 122b. A first splicing structure 124b is provided on the first shell 1231b, and a second splicing structure 125b is provided on the second shell 1232b. The first splicing structure 124b and the second splicing structure 125b are detachably connected. This allows the first shell 1231b and the second shell 1232b to be easily assembled and connected to each other. Compared to a one-piece fixing shell 123b structure, this reduces the manufacturing difficulty of the fixing shell 123b and improves the ease of assembly. In other words, compared to the longer one-piece fixing shell 123b, the split fixing shell 123b reduces the manufacturing difficulty in achieving overall flatness consistency, and allows for individual installation during assembly, reducing the operating space required for assembly and facilitating assembly.

[0123] In some embodiments, the fixed shell 123b may be configured to be formed by splicing together more splicing units (e.g., first shell 1231b, second shell 1232b, third shell, etc.) according to design requirements, and the splicing units are connected to each other by setting splicing structure to form a whole.

[0124] Specifically, the splicing structure can be configured as a matching hook assembly, a mortise and tenon joint, or a flexible plug-in structure, etc., allowing the first shell 1231b and the second shell 1232b to be quickly assembled and connected when spliced ​​together. Compared to connections using screws or adhesives, this method requires less assembly work and is more convenient.

[0125] In some embodiments, as shown in FIG11, a first assembly structure 126b is provided on the heating element 122b, and a second assembly structure 127b is also provided on both the first shell 1231b and the second shell 1232b. The first assembly structure 126b and the second assembly structure 127b are connected. That is, both the first shell 1231b and the second shell 1232b are provided with the second assembly structure 127b, and both can be connected to the first assembly structure 126b on the heating element 122b. In this way, the heating element 122b can be fixedly installed on the first shell 1231b and the second shell 1232b, and the assembly connection is convenient, stable and reliable.

[0126] Specifically, the first assembly structure 126b can be configured as a sliding groove, and the second assembly structure 127b can be configured as a connecting block that can be inserted into the sliding groove to achieve connection. The first assembly structure 126b can also be configured as a hook, and the second assembly structure 127b can be configured as a snap-fit ​​position for hook connection. The first assembly structure 126b can also be configured as a plug, and the second assembly structure 127b can be configured as a plug hole for plug insertion to achieve a locking connection. Of course, it is understandable that the configuration of the first assembly structure 126b and the second assembly structure 127b can be interchanged, provided that a mating connection is achieved. This method of achieving assembly connection between the fixed shell 123b and the heating element 122b through a connecting structure not only facilitates connection and requires minimal operation, improving assembly convenience, but also ensures high connection reliability, preventing loosening and improving product quality stability.

[0127] In other embodiments, a first assembly structure 126b may be provided on the heating element 122b, one of the first shell 1231b and the second shell 1232b is integrally formed with the heating element 122b, and the other of the first shell 1231b and the second shell 1232b is further provided with a second assembly structure 127b, with the first assembly structure 126b and the second assembly structure 127b connected together. That is, either the first shell 1231b or the second shell 1232b is integrally formed with the heating element 122b, and the other is detachably connected to the heating element 122b by a matching connection structure, while the two fixed shells 123b are still connected by a splicing structure. In this way, assembly and connection can be completed quickly, and the connection reliability is good.

[0128] The hair styling device provided in this embodiment provides power to the styling head 1 by means of a battery installed inside the handle 2. Alternatively, it can be powered by a power cord connected to AC mains. As shown in Figure 2, in this embodiment, the bottom cover 28 is provided with a power connection component 29 for connecting to an external power source. The power connection component 29 can be connected to AC mains to directly power the styling head 1 or to charge the battery.

[0129] Specifically, when configured for battery power, the power connection assembly 29 can be configured with multiple power connection springs, spaced apart to reduce electrical interference and increase electrical connection safety. The multiple power connection springs may include at least a grounding spring, a positive spring, and a negative spring. For example, the number of power connection springs is five. The multiple power connection springs can be used to achieve different power connection functions, or two of the multiple power connection springs can be used to achieve the same power connection function. Thus, at least two of the multiple power connection springs can be used interchangeably, and if one malfunctions, the other can still provide a reliable electrical connection.

[0130] Optionally, each contact spring pin can be fixed on the same mounting base, and the mounting base can also rotate relative to the bottom cover 28, thereby allowing for flexible adjustment of the charging conductive connection position and improving ease of use. When the mounting base can rotate relative to the bottom cover, an annular conductive plate can be provided on the handle 2 for each contact spring pin to slide and contact the conductive surface, so that a reliable electrical connection can still be maintained when each contact spring pin rotates.

[0131] In some embodiments, when configured to be powered by direct external mains power, the power connection component 29 can be configured to include a wire and a connector plug, and power can be obtained by connecting the plug to a mains socket. This also makes it convenient to obtain the power required for use and is easy to use.

[0132] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
