[0030] like Figure 1 and Figure 2 As shown, in a first aspect, this utility model embodiment provides a handle 10 for connecting a hair styling head 20. As... Figure 3 and Figure 4As shown, the handle 10 includes a housing 1, a bottom cover 2, and an electrical connector 3. The housing 1 has an internal mounting cavity 11, which provides space for mounting components (not shown). One axial end of the housing 1 has an opening 12 communicating with the mounting cavity 11, and the other axial end of the housing 1 is used to connect to a hair styling head 20. The bottom cover 2 is located at the end of the housing 1 where the opening 12 is formed, at least partially closing the opening 12. That is, one end of the housing 1 has an opening 12, and the other end is closed; the hair styling head 20 is connected to the closed end, and the bottom cover 2 is located at the open end. It should be noted that the "axial direction of the handle 10" refers to the direction of the central axis of the handle 10, which is also the length direction of the handle 10 in a three-dimensional coordinate system. It can be understood that the axial direction of the handle 10 is a collection of parallel line extension directions, not the extension direction of a single line. One end of the electrical connector 3 passes through the bottom cover 2 and is electrically connected to the components within the mounting cavity 11; the other end of the electrical connector 3 is used for electrical connection to a power source. It is understood that the electrical connector 3 can be a power cord with a plug, in which case the handle 10 can be directly connected to power; the electrical connector 3 can also be a power terminal that can be connected to a charging cable, in which case the handle 10 can store electricity. This utility model does not limit the specific type of the electrical connector 3, as long as one end of the electrical connector 3 can be connected to a power source.

[0031] like Figure 3 and Figure 4 As shown, the bottom cover 2 and the housing 1 are axially snapped together, meaning the bottom cover 2 and the housing 1 are detachably connected. By inserting the bottom cover 2 into the housing 1 axially, the bottom cover 2 can be snapped onto the open end of the housing 1, thus achieving the assembly operation of the bottom cover 2 and the housing 1. After the bottom cover 2 is connected to the electrical connector 3, it forms an assembly (see reference). Figure 5This component seals the opening 12 of the housing 1, reducing the possibility of water or dust entering the mounting cavity 11. Furthermore, since this component is located at the open end of the housing 1, there is no need to open holes in other locations on the housing 1 to assemble the electrical connector 3. This makes it feasible for the housing 1 to form an integrally extended outer contour along the axial direction, reducing gaps on the outer contour of the housing 1 and helping to maintain the overall shape of the handle 10. Along the axial direction, the electrical connector 3 is snapped onto at least one of the bottom cover 2 and the housing 1. Specifically, the electrical connector 3 can be snapped onto only the bottom cover 2, only the housing 1, or both. Regardless of which part the electrical connector 3 is snapped onto, it passes through the bottom cover 2. The bottom cover 2 supports and limits the electrical connector 3 to maintain the stability of the assembled electrical connector 3, thereby maintaining the reliability of the electrical connection and ensuring a reliable power circuit when the handle 10 is connected to the power source. Furthermore, the bottom cover 2 is snapped onto the housing 1, and the bottom cover 2 is easy to disassemble and assemble, making the assembly structure of the electrical connector 3 relatively simple and easy to implement, thereby improving the production efficiency of the handle 10. In addition, compared with threaded or adhesive connections, the snap-fit ​​design of the electrical connector 3 is simple in structure and easy to disassemble and assemble, which facilitates the rework of defective electrical connectors 3 during the production stage. For example, if the electrical connector 3 cannot form a power circuit, or if the appearance of the electrical connector 3 is damaged, the defective electrical connector 3 can be quickly removed for rework.

[0032] This utility model provides a handle 10 for connecting a hair styling head 20. The handle 10 includes a housing 1, a bottom cover 2, and an electrical connector 3. The housing 1 has an internal mounting cavity 11. One axial end of the housing 1 has an opening 12 communicating with the mounting cavity 11, and the other axial end of the housing 1 is used to connect the hair styling head 20. The bottom cover 2 is located at the end of the housing 1 with the opening 12. One end of the electrical connector 3 passes through the bottom cover 2 and is used for electrical connection with components within the mounting cavity 11. The other end of the electrical connector 3 is used for electrical connection with a power source. The electrical connector 3 passes through the bottom cover 2, and the bottom cover 2 supports and limits the electrical connector 3, which helps maintain the stability of the electrical connector 3 after assembly, so that the handle 10 forms a more reliable power-carrying circuit. Furthermore, the electrical connector 3 cooperates with the bottom cover 2 to close the opening 12 at the axial end of the housing 1, which helps the housing 1 maintain its integrally extended axial contour, reducing the impact of assembling the electrical connector 3 on the overall shape of the handle 10. The bottom cover 2 and the housing 1 are axially snapped together. The electrical connector 3 is snapped onto at least one of the bottom cover 2 and the housing 1 axially, and closes the opening 12 with the bottom cover 2. Both the bottom cover 2 and the electrical connector 3 are assembled through a snap-fit ​​structure. Compared with threaded or adhesive connections, the snap-fit ​​structure is simpler and easier to assemble and disassemble the electrical connector 3 and the bottom cover 2, thus facilitating rework of the electrical connector 3 and enabling rapid assembly of the handle 10, thereby improving the production efficiency of the handle 10.

[0033] In some embodiments, such as Figure 3 and Figure 4 As shown, the bottom cover 2 is a rotating body, meaning its cross-sectional shape is circular. The cross-sectional direction of the rotating body is radial. The bottom cover 2 has a radially protruding latch 211, and the housing 1 has a corresponding slot 13 that matches the latch 211. By axially inserting the bottom cover 2 and the housing 1, the latch 211 is inserted into the slot 13. The latch 211 and the slot 13 are locked circumferentially, preventing relative rotation between the bottom cover 2 and the housing 1, thus forming a fixed connection. This structure is simple and easy to manufacture.

[0034] In some embodiments, such as Figure 3 and Figure 4 As shown, multiple latches 211 and slots 13 are provided, with one latch 211 engaging with one slot 13 to form a group of engagements. Multiple groups of engagements are formed by each latch 211 and each slot 13. Each group of engagements is at least circumferentially spaced; that is, each group can be distributed only circumferentially. Alternatively, each group can be distributed circumferentially and axially. Each latch 211 and each slot 13 engages with each other at at least multiple positions in the circumferential direction to increase the contact area between the latch 211 and the slot 13, improving the stability of the bottom cover 2 connected to the housing 1 and reducing the possibility of the bottom cover 2 separating from the housing 1 and affecting user operation. The bottom cover 2 stably supports and limits the electrical connector 3, facilitating the stability of the electrical connector 3 after assembly, so that a more reliable power circuit is formed when the handle 10 is connected to the power source.

[0035] In some embodiments, such as Figure 3 and Figure 4 As shown, the bottom cover 2 is also provided with a first positioning part 212, and the housing 1 is provided with a second positioning part 14. Both the second positioning part 14 and the first positioning part 212 extend axially and are axially inserted together. For example, the first positioning part 212 is a protrusion protruding from the bottom cover 2 axially, and the second positioning part 14 is a groove extending axially, which penetrates the end face of the housing 1 connected to the bottom cover 2, so that the first positioning part 212 and the second positioning part 14 are inserted and locked. Of course, in some possible embodiments, the second positioning part 14 is a protrusion protruding from the housing 1 axially, and the first positioning part 212 is a groove extending axially, which penetrates the end face of the bottom cover 2 connected to the housing 1. The first positioning part 212 and the second positioning part 14 form a positioning reference for the insertion of the bottom cover 2 and the housing 1. By aligning the first positioning part 212 and the second positioning part 14, the assembly position of the housing 1 and the bottom cover 2 can be checked, so that the latch 211 can smoothly engage into the slot 13, facilitating the installation of the bottom cover 2 on the housing 1.

[0036] In some embodiments, such as Figure 3 and Figure 4As shown, multiple first positioning parts 212 and second positioning parts 14 are provided. One first positioning part 212 and one second positioning part 14 are inserted and locked to form a positioning group. Each first positioning part 212 and each second positioning part 14 form multiple positioning groups. Each positioning group is distributed circumferentially, which increases the contact area between the bottom cover 2 and the housing 1 in the circumferential direction, improves the stability of the bottom cover 2 and the housing 1 after assembly. At the same time, each positioning group calibrates the bottom cover 2 and the housing 1 at multiple positions, which has a higher fault tolerance rate, facilitates user operation, and allows for smooth assembly of the bottom cover 2.

[0037] In some embodiments, such as Figure 4 and Figure 5 As shown, at least a portion of each latch 211 is axially spaced from the first positioning part 212 and is radially flush with the first positioning part 212. That is, at least a portion of each latch 211 has its axial projection coincide with the first positioning part 212. For example, if the bottom cover 2 has four latches 211 and two first positioning parts 212, then two latches 211 are axially spaced from the first positioning parts 212, and their axial projections coincide with the first positioning parts 212. This can be simply understood as the latches 211 and the first positioning parts 212 being radially flush. The latches 211 and the first positioning parts 212 have the same phase angle, allowing them to be integrally injection molded without segmented processing. For example, it eliminates the need to rotate the bottom cover 2 45° after processing the first positioning part 212 before re-forming the latches 211, thus facilitating the processing of the bottom cover 2. In addition, the latch 211 and the first positioning part 212 are roughly in a straight line, which also makes it easy for the bottom cover 2 to be smoothly inserted into the housing 1.

[0038] In some embodiments, such as Figure 3 and Figure 4 As shown, the bottom cover 2 includes a body 21 and a shoulder 22. The body 21 passes through the housing 1 and is fitted over the electrical connector 3. The body 21 is inserted into the housing 1, which helps maintain the shape of the outer wall of the housing 1 and reduces the impact on the overall shape of the handle 10. The shoulder 22 protrudes radially from the body 21 and abuts against one end of the housing 1 axially. The latch 211 protrudes radially from the body 21, and the first positioning part 212 is axially positioned on the body 21. The bottom cover 2 is inserted axially until the shoulder 22 abuts against one end of the housing 1, indicating that the bottom cover 2 is installed in place. The shoulder 22 provides physical feedback for the bottom cover 2 to be installed in place, making it easier for the user to operate and install the bottom cover 2.

[0039] In some embodiments, such as Figure 3 and Figure 4As shown, the first positioning part 212 is a plug-in block protruding along the axial direction of the body 21, and the second positioning part 14 is a groove formed inside the housing 1, in which the plug-in block is inserted. After placing the plug-in block in the groove, it is inserted axially until the shoulder 22 abuts against the end face of the housing 1, thus assembling the bottom cover 2. Compared to the embodiment where the plug-in block is provided on the longer housing 1, this embodiment of the present invention provides the plug-in block on the shorter bottom cover 2. The bottom cover 2 is smaller in size, which facilitates mold design and facilitates the molding of the plug-in block, making it easier to process and manufacture.

[0040] In some embodiments, such as Figure 3 and Figure 4 As shown, part of the electrical connector 3 passes through the bottom cover 2 into the mounting cavity 11 and is snapped into the housing 1. That is, the electrical connector 3 is snapped into the housing 1 via the bottom cover 2, and the bottom cover 2 supports the electrical connector 3. The disengagement path of the electrical connector 3 starts from the end face of the electrical connector 3 that extends into the mounting cavity 11 and ends at the end face of the bottom cover 2. The path is relatively long, making it more difficult for the electrical connector 3 to disengage. This helps to maintain the assembly stability of the electrical connector 3, so that a more reliable power circuit can be formed when the handle 10 is connected to the power source.

[0041] In some embodiments, such as Figure 3 and Figure 4 As shown, a retaining rib 15 protrudes from the inner side of the housing 1, and a limiting groove 31 is formed in the electrical connector 3, with the retaining rib 15 inserted into the limiting groove 31. When the groove is cut inside the housing 1, the depth of the groove is limited by the thickness of the housing 1 wall. However, the housing 1 provided in this embodiment of the present invention has a retaining rib 15 protruding inside, which is inserted into the limiting groove 31 of the electrical connector 3. The depth of the retaining rib 15 is not limited by the thickness of the housing 1 wall, which can increase the area of ​​engagement between the housing 1 and the electrical connector 3, so that the electrical connector 3 is more stably engaged with the housing 1.

[0042] In some embodiments, such as Figure 4 and Figure 5 As shown, the limiting groove 31 is circumferentially formed around the electrical connector 3, and the snap-fit ​​rib 15 is circumferentially formed around the housing 1. Both the limiting groove 31 and the snap-fit ​​rib are annular. At any position in the circumferential direction, the limiting groove 31 is snapped into the snap-fit ​​rib 15. The contact area between the snap-fit ​​rib 15 and the limiting groove 31 is relatively large, which helps to improve the stability of the connection between the electrical connector 3 and the housing 1, so that the handle 10 forms a more reliable power-carrying circuit.

[0043] In some embodiments, such as Figure 2As shown, the electrical connector 3 is rotatably connected to both the housing 1 and the bottom cover 2. Specifically, regardless of whether the electrical connector 3 is a power cord with a plug or a terminal connected to a charging cable, the power cord and charging cable are prone to tangling when the user holds the handle 10 to curl and / or straighten hair due to different usage angles or directions. The electrical connector 3 provided by this utility model rotates relative to the housing 1 and the bottom cover 2, reducing the possibility of tangling of the power cord and charging cable, thus facilitating the user's use of the handle 10 to curl and / or straighten hair and improving the user experience.

[0044] Secondly, this utility model embodiment also provides a hair styling tool, such as... Figure 1 As shown, the hair styling device includes the handle 10 described in the first aspect, and thus has the same technical effect, namely, it has a smooth overall shape, which facilitates the assembly and installation of the electrical connector 3, and supports and limits the electrical connector 3 with a relatively simple structure, so that the electrical connector 3 can make a more reliable electrical connection, so that when the handle 10 is connected to the power source, a reliable power-carrying circuit is formed.

[0045] like Figure 1 As shown, the hair styling tool also includes a hair styling head 20, which is connected to the handle 10. Specifically, the hair styling head 20 can be detachably connected to the handle 10 via a threaded connection structure or a snap-fit ​​structure. Alternatively, the hair styling head 20 can share the housing 1 of the handle 10 and be fixedly connected to it. The hair styling head 20 is used for curling and / or straightening hair. It can function solely as a curling head, or solely as a straightening head, or it can combine both functions. For example, the hair styling head 20 can be equipped with a curling iron composed of two openable plates. The opposite side of the two plates is flat, while the opposite side is curved. Specifically, when the two plates are open, the user can place hair into the gap between them, then close the plates again to clamp the hair, heat the hair, and pull it in a generally straight direction to straighten it. With both plates closed, users can wrap their hair around the outer curved surfaces of the plates and heat it to achieve curls. This allows users to choose the appropriate hair treatment method according to their needs, offering great flexibility.

[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.
