[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model 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 of the present utility model and are not intended to limit the present utility model.

[0027] 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 utility model will not be described separately.

[0028] 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.

[0029] 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.

[0030] Firstly, such as Figure 1 As shown, this embodiment of the utility model provides a handle 1 for mounting a hair styling head 2. After the handle 1 is connected to the hair styling head 2, a hair styling tool is formed, capable of styling hair. Figure 2 and Figure 3As shown, the handle 1 includes a housing 11, a circuit board 12, and a motor 13. The housing 11 supports the hair styling head 2 and is held by the user. The housing 11 has an internal receiving space 111 (see reference). Figure 3 Both circuit board 12 and motor 13 are housed within the receiving space 111. Motor 13 is electrically connected to circuit board 12. Hair styling head 2 is electrically connected to circuit board 12 via an electrical connection wire (not shown in the figure). For example, heating element 22 in hair styling head 2 is electrically connected to circuit board 12 via the electrical connection wire. Circuit board 12 controls heating element 22 to heat air, so that heating element 22 can perform styling treatment on hair, forming curly or straight hair. Motor 13 is drive-connected to hair styling head 2. Using the rotational power of motor 13, rotating components in hair styling head 2 (e.g., Figure 6 The hair claw 23 in the middle rotates, and the rotating part (e.g.) Figure 6 After the hair claw 23 rotates, it automatically wraps the hair around the heating element (such as the heating element 22), achieving automatic hair wrapping without the need for manual wrapping, thus improving the convenience of hair wrapping and reducing the difficulty of use for users. The heating element (such as the heating element 22) heats the air and transfers the heat to the hair to shape the hair into curls.

[0031] like Figure 3 and Figure 6 As shown, to enable the motor 13 to transmit greater torque to the claw 23, a shaft hole can be formed on the output shaft 131 of the motor, and the cross-section of the shaft hole can be polygonal, for example, a quadrilateral, pentagon, or hexagon. At least a portion of the claw 23 extends into a polygonal prism adapted to the shaft hole and is inserted into it. This reduces wear and vibration between the motor 13 and the claw 23, thereby reducing transmission losses, improving transmission efficiency, and simultaneously enhancing the rotational stability of the claw 23.

[0032] like Figure 3 and Figure 4As shown, the end of the housing 11 used for connecting to the hair styling head 2 has a wire hole 112 and a shaft through hole 113. The output shaft 131 of the motor passes through the shaft through hole 113. Multiple wire holes 112 are provided, spaced apart from each other and all spaced apart from the shaft through hole 113. That is, the wire holes 112 are through holes different from the shaft through hole 113. The output shaft 131 of the motor 13 passes through the shaft through hole 113 without being connected to any of the wire holes 112. An electrical connection wire passes through at least one wire hole 112. It is possible that an electrical connection wire passes through all wire holes 112, or only one wire hole 112, or some wire holes 112. Regardless of which embodiment the electrical connection wire passes through, it remains within the wire hole 112 and is not connected to the shaft through hole 113. The through hole 113 is used only for the output shaft 131 of the motor 13, and the wire hole 112 is used only for the electrical connection wire. The layout of the electrical connection wire does not occupy the installation space of the through hole 113. The wire hole 112 surrounds the circumference of the electrical connection wire, thus confining the position of the electrical connection wire within the wire hole 112, resulting in a more orderly layout of the electrical connection wire. Moreover, compared with the related technology that uses the through hole to pass the electrical connection wire, this embodiment of the utility model uses the wire hole 112, which is independent of the through hole 113, to pass the electrical connection wire, making the electrical connection wire independent of the installation space of the output shaft 131 of the motor 13, thereby improving the neatness of the electrical connection wire.

[0033] The handle 1 provided in this embodiment of the utility model is used to connect a hair styling head 2. The handle 1 includes a housing 11, a circuit board 12, and a motor 13. The housing 11 supports the hair styling head 2, and a receiving space 111 is formed inside the housing 11. The circuit board 12 and the motor 13 are both disposed in the receiving space 111. The circuit board 12 is electrically connected to the hair styling head 2 via an electrical connection wire, and the motor 13 is electrically connected to the circuit board 12 and is drively connected to the hair styling head 2. A wire hole 112 and a shaft through hole 113 are provided at the end of the housing 11 connected to the hair styling head 2. The output shaft 131 of the motor 13 passes through the shaft through hole 113. Multiple wire holes 112 are provided, and each wire hole 112 is spaced apart from each other and spaced apart from the shaft through hole 113. The electrical connection wire passes through at least one wire hole 112. This design allows the wiring space for electrical connection cables to be independent of the installation space of the output shaft 131 of the motor 13. The position of the electrical connection cables is restricted to the wire hole 112. Multiple wire holes 112 can be used to divide the wiring into modules and areas, which improves the neatness of the electrical connection cables. This makes it easier to connect the electrical connection cables to the circuit board 12 during the assembly stage, and also facilitates subsequent circuit inspection and maintenance of the finished product.

[0034] In some embodiments, such as Figure 3 and Figure 4As shown, the electrical connection includes conductors (not shown) and ribbon cables (not shown). It should be explained that the ribbon cable, also called a flexible circuit board, is mainly used for data transmission, while the conductor represents the wire harness. Both are connected to the circuit board 12 to achieve the electrical connection between the hair styling head 2 and the handle 1. The cable through-hole 112 includes alternately spaced ribbon cable through-holes 1121 and conductor through-holes 1122. The ribbon cable through-hole 1121 is for the ribbon cable to pass through, and the conductor through-hole 1122 is for the conductor. The installation space for the ribbon cable and the installation space for the conductor are independent of each other. This arrangement allows cables to be threaded through different through-holes according to their type, restricting the freedom of movement of various cables in different areas. Users can sort cables in specific areas as needed, facilitating quick sorting of the required cables for connection to the circuit board 12 during the assembly stage. This improves the efficiency of circuit connection and facilitates subsequent circuit inspection and maintenance of the finished product.

[0035] In some embodiments, such as Figure 3 and Figure 4 As shown, there is one ribbon cable via 1121 and at least two wire vias 1122. Specifically, the multiple wire vias 1122 provide multiple wire passing positions. Wires can be passed through all of the multiple wire vias 1122, or wires can be passed through one or a portion of the multiple wire vias 1122. In embodiments where wires are passed through one or a portion of each wire via 1122, the user can pass wires into any wire via 1122 as needed without matching or selection, improving the convenience of wire passing. In some possible embodiments, wires are passed through each wire via 1122, and each wire via 1122 can pass wires through at least two areas, so that the wires are distributed in at least two areas, forming a wire group within each wire via 1122, making the modular, zoned wire passing effect more intuitive. Different types of wires can be run through unused wire vias 1122. For example, a single-core wire can be run through one wire via 1122, and a multi-core wire through another wire via 1122. When users need to sort wires, they only need to go to the specific wire via 1122 for sorting, which improves the neatness of the wire layout. In general, one ribbon cable can realize multiple signal transmissions. Therefore, it is only necessary to set up one ribbon cable and open one ribbon cable via 1121 to run the ribbon cable, which reduces the number of openings and helps to reduce the processing difficulty of the housing 11.

[0036] In some embodiments, such as Figure 4As shown, the wire through-hole 112 includes a first wire through-hole 1122a and a second wire through-hole 1122b disposed opposite each other in a first direction, and a ribbon cable through-hole 1121 and a pivot through-hole 113 disposed opposite each other in a second direction; wherein, the first direction and the second direction are perpendicular. Both the first direction and the second direction are radial, therefore, both the first direction and the second direction are perpendicular to the length direction (axial direction) of the housing 11. In the schematic diagram of this application, the direction where N1 is located represents the first direction, and the direction where N2 is located represents the second direction. The two wire through-holes 1122 are in the same direction to facilitate the partitioning effect of the wires and also to facilitate the partitioning of the wires and the ribbon cable.

[0037] In some embodiments, such as Figure 3 and Figure 5 As shown, the housing 11 is provided with a limiting part 114. Along the axial direction of the motor 13, the limiting part 114 abuts against the motor 13, and the output shaft 131 of the motor 13 passes through the limiting part 114. The limiting part 114 forms the mounting reference for the motor 13. By determining whether the motor 13 abuts against the limiting part 114 along the axial direction, it can be visually indicated whether the motor 13 is installed correctly. Along the radial direction of the motor 13, the limiting part 114 abuts against the circuit board 12, that is, the limiting part 114 also forms the mounting reference for the circuit board 12. By determining whether the circuit board 12 abuts against the limiting part 114 along the radial direction, it can be visually indicated whether the circuit board 12 is installed correctly. Through the limiting part 114, the mounting positions of the motor 13 and the circuit board 12 can be initially calibrated, reducing the assembly difficulty of the motor 13 and the circuit board 12.

[0038] In some embodiments, such as Figure 3 and Figure 5 As shown above, the limiting part 114 abuts against the motor 13 and the circuit board 12, and both the motor 13 and the circuit board 12 are disposed within the receiving space 111. Therefore, the limiting part 114 is formed within the receiving space 111. A wire-holding groove 1141 is provided on the limiting part 114, and the wire is held in place within the wire-holding groove 1141. The wire-holding groove 1141 further restricts the position of the wire within the receiving space 111, allowing the wire to be laid out more neatly within the receiving space 111, further improving the neatness of the electrical connection wiring.

[0039] In some embodiments, such as Figure 3 and Figure 5As shown, the limiting part 114 has multiple wire-locking grooves 1141, each corresponding to a wire through hole 1122. That is, along the axial direction, one wire-locking groove 1141 communicates with one wire through hole 1122. When there are multiple wire through holes 1122, there are also multiple wire-locking grooves 1141, and the number of wire-locking grooves 1141 is equal to the number of wire through holes 1122. The wire-locking grooves 1141 can restrict each group of wires passing through the wire through holes 1122 within the receiving space 111, fixing the degree of freedom of each group of wires within the receiving space 111, so that each group of wires is arranged more neatly within the receiving space 111.

[0040] In some embodiments, such as Figure 3 and Figure 5 As shown, the limiting part 114 is also provided with a mounting groove 1142. A part of the mounting groove 1142 is used for the output shaft 131 of the motor 13 to pass through and be installed, and the other part of the mounting groove 1142 is used for the ribbon cable to pass through. It can be understood that there is a gap between the motor 13 and the circuit board 12, and the radial dimension of the mounting groove 1142 covers the gap between the motor 13 and the circuit board 12. After the ribbon cable passes through the ribbon cable through hole 1121 to the receiving space 111, the part of the ribbon cable passes through the mounting groove 1142 between the motor 13 and the circuit board 12, which restricts the freedom of the ribbon cable in the receiving space 111, making the arrangement of the ribbon cable more regular.

[0041] Secondly, such as Figure 1 As shown, this embodiment of the invention also provides a hair styling head 2, which is connected to the handle 1 described in the first aspect. The hair styling head 2 is capable of at least curling hair. In some possible implementations, the hair styling head 2 can also simultaneously curl and straighten hair. For example, the hair styling head 2 can be equipped with a curling iron, which consists of two openable plates. The opposite sides of the two plates are flat, and the opposite sides are curved, to wrap around the hair and achieve curling. Specifically, 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, heat the hair, and pull the hair in a generally straight direction to achieve straightening. 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 curling.

[0042] like Figure 6As shown, the hair styling head 2 includes a connector 21, a heating element 22, and hair claws 23. The heating element 22 is mounted on the connector 21 and is used to heat the hair for styling. The hair claws 23 are sleeved around the heating element 22 and can rotate around it. After driving the motor 13, the output shaft 131 of the motor 13 drives the hair claws 23 to rotate, causing the hair claws 23 to wrap the hair around the outside of the heating element 22. The heat from the heating element 22 is transferred to the hair to style it into curls. The output shaft 131 of the motor 13 passes through the connector 21 and is connected to the hair claws 23. Both the heating element 22 and the hair claws 23 are electrically connected to the circuit board 12 via electrical connection lines. The circuit board 12 controls the working state of the heating element 22 and the hair claws 23. For example, the circuit board 12 can control the heating temperature and / or heating time of the heating element 22, and the circuit board 12 can also control the rotation direction and / or rotation speed of the hair claws 23 by controlling the rotation direction and / or rotation speed of the motor 13. The hair styling head 2 is highly flexible and can be used in a variety of scenarios, improving the user experience.

[0043] In some embodiments, such as Figure 7 As shown, the connector 21 has a through-hole 211, a wire-shielding groove 212, and a shaping groove 213. The through-hole 211 allows the output shaft 131 of the motor 13 to pass through, the wire-shielding groove 212 allows the power supply connection wire to pass through, and at least one shaping groove 213 is provided. The through-hole 211, wire-shielding groove 212, and shaping groove 213 are spaced apart from each other. Specifically, multiple wire-shielding grooves 212 and shaping grooves 213 can be provided, or multiple of one type of wire-shielding groove 212 and shaping groove 213 can be provided. This application does not limit the number of wire-shielding grooves 212 and shaping grooves 213, nor does it limit the shape of the through-hole 211, wire-shielding groove 212, and shaping groove 213. However, in general, the shaping groove 213 is independent of the through-hole 211 and wire-shielding groove 212, and the shaping groove 213 does not have a connection relationship with the electrical connection wire, nor does it have a connection relationship with the output shaft 131 of the motor 13. In the through hole 211, the avoidance groove 212 and the molding groove 213, at least the molding groove 213 is connected to the gate of the connector 21 injection molding to reduce the possibility of the connector 21 injection molding deformation.

[0044] Specifically, the gate is the inlet in the cavity of an injection mold used to allow molten plastic to enter. It refers to the channel from the runner to the mold cavity and is also the shortest and smallest cross-section part in the gating system. Providing a molding groove 213 connecting to the gate reduces internal stress at the gate, lowering the possibility of stress concentration and deformation of the plastic part. Generally, the more gates there are, the better the stress is dispersed. Therefore, in some possible implementations, the through-hole 211, the bypass groove 212, and the molding groove 213 can all be connected to the gate, or one or two of these can be connected, but at least the molding groove 213 must be connected to the gate. The additional molding groove 213 increases the number of slots in the connector 21, thereby increasing the space where the mold can support the cavity and also reducing the possibility of deformation of the connector 21 during injection molding.

[0045] Thirdly, this utility model embodiment also provides a hair styling tool, which is at least used for curling hair. The hair styling tool includes the handle 1 described in the first aspect and the hair styling head 2 described in the second aspect, with the hair styling head 2 connected to the handle 1. Therefore, the hair styling tool has the same technical effect, namely, the electrical connection wires in the hair styling tool are arranged in a relatively neat manner, making it convenient for users to sort the electrical connection wires as needed, so as to quickly realize circuit connection during the assembly stage, and to facilitate circuit inspection and maintenance.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
