Description

Technical Field

[0001] This application relates to the field of hair styling appliances, and more particularly to a hair curler. Background Technology

[0002] A curling iron is a common hair styling device that can curl hair. The specific way to use it is to hold the handle of the curling iron and wrap the hair around the heating unit of the curling iron. The heating unit irons the hair, and the curling components of the curling iron rotate the hair. After a period of time, the hair can achieve a curly effect.

[0003] In related technologies, the handle of a hair curler is formed as an integral columnar structure. During assembly, the internal components such as the drive module of the hair curler need to be pushed into the handle along the axial direction, which is inconvenient to operate and results in low installation stability of the internal components such as the drive module.

The internal components of the hair curler, such as the drive module, have sufficient installation and operation space and can dock with the housing in different directions. The first half-shell and the second half-shell are then assembled by a first snap-fit ​​structure and a second snap-fit ​​structure.

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

[0045] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0046] This application provides a hair curler 1, please refer to... Figures 1 to 6 The hair curler 1 includes a curling component 10 and a handle component 11.

[0047] The hair curling component 10 is used to curl hair, and the handle component 11 can be used as a handheld end, allowing the user to hold the handle component 11 to perform the hair curling operation.

[0048] Specifically, the handle assembly 11 is located on one side of the curling assembly 10 along the axial direction.

[0049] It should be noted that the axial direction refers to the direction of the central axis of the hair curling component 10. In this embodiment, the axial directions of the handle assembly 11, the hair curling component 10, and the hair curler 1 are in the same direction. When the hair curling component 10 rotates, the axial direction is the direction of the rotation axis of the hair curling component 10.

[0050] For example, the handle assembly 11 is generally cylindrical to facilitate user grip.

[0051] Handle assembly 11 includes housing 112, see [link / reference] Figure 5 The housing 112 includes a first half-shell 1121 and a second half-shell 1122 that are separately arranged. The first half-shell 1121 and the second half-shell 1122 are joined together along a first direction to form an accommodating space 11a, wherein the first direction is perpendicular to the axial direction of the hair curler 1.

[0052] The curling iron 1 includes a drive module 12, at least a portion of which is disposed in the receiving space 11a and connected to the curling assembly 10. The drive module 12 is used to drive the curling assembly 10 to rotate.

[0053] In other words, the first half-shell 1121 and the second half-shell 1122 are manufactured separately and joined together along the first direction to define the accommodating space 11a.

[0054] Specifically, the accommodating space 11a provides installation space and protection for the drive module 12, preventing it from being affected by external dust or other factors. The drive module 12 provides driving force to drive the curling component 10 to rotate, thereby enabling the curling function of the curling component 10.

[0055] It is understood that the specific construction of the drive module 12 is not limited; for example, the drive module 12 may include a motor. The curling assembly 10 is connected to the power output shaft of the motor.

[0056] For example, the first half-shell 1121 and the second half-shell 1122 can each be a hollow semi-cylindrical structure, and the shell 112 formed by the docking of the first half-shell 1121 and the second half-shell 1122 can be approximately a hollow cylindrical structure. Components of the curling iron 1, such as the drive module 12, can be installed in the receiving space 11a defined by the first half-shell 1121 and the second half-shell 1122.

[0057] Specifically, with the first half-shell 1121 and the second half-shell 1122 designed separately and connected along the first direction, the internal components such as the drive module 12 of the curling iron 1 can be installed and connected with one of the first half-shell 1121 and the second half-shell 1122 in different directions first. After the connection is completed, the first half-shell 1121 and the second half-shell 1122 are then connected. This facilitates the stable and convenient installation of the internal components such as the drive module 12 into the receiving space. The first half-shell 1121 and the second half-shell 1122 protect the internal components such as the drive module 12 and increase the installation stability.

[0058] The first half-shell 1121 has a first snap-fit ​​structure 11211, and the second half-shell 1122 has a second snap-fit ​​structure. The first snap-fit ​​structure 11211 and the second snap-fit ​​structure are detachably connected.

[0059] In other words, the first half-shell 1121 and the second half-shell 1122 are connected by a snap-fit ​​mechanism. This snap-fit ​​mechanism increases the stability of the connection between the first half-shell 1121 and the second half-shell 1122, making them less prone to loosening. Furthermore, there is no need to connect the first half-shell 1121 and the second half-shell 1122 using screws, making the connection convenient and facilitating assembly and disassembly.

[0060] Understandably, in related technologies, the housing is formed as an integral columnar structure. During assembly, internal components such as the hair curler's drive module need to be pushed axially into the housing for docking, which is inconvenient and results in low installation stability of internal components such as the drive module.

[0061] The hair curler 1 provided in this application embodiment uses a split design of first half-shell 1121 and second half-shell 1122 to enclose a space 11a for accommodating internal components such as the drive module 12. On the one hand, this facilitates the installation and docking of internal components such as the drive module 12 from different directions and angles, increasing docking convenience and installation stability, making the assembly of the hair curler 1 more reliable. On the other hand, the first half-shell 1121 and second half-shell 1122 are docked through the snap-fit ​​of the first snap-fit ​​structure 11211 and the second snap-fit ​​structure, which has high stability and is easy to disassemble and assemble. Furthermore, docking can be achieved without the use of screws or other auxiliary structures, increasing the structural simplicity of the hair curler 1.

[0062] The specific construction of the first snap-fit ​​structure 11211 and the second snap-fit ​​structure is not limited.

[0063] In some embodiments, please refer to Figure 5 and Figure 6 A portion of the structure of the first half-shell 1121 extends toward the second half-shell 1122 in the first direction to form a first snap-fit ​​structure 11211. The first snap-fit ​​structure 11211 is provided with a snap-fit ​​groove 11211a. The second snap-fit ​​structure includes a snap-fit ​​block 11221 protruding from the inner wall surface of the second half-shell 1122. The snap-fit ​​block 11221 is inserted into the snap-fit ​​groove 11211a.

[0064] Specifically, the engagement of the locking block 11221 and the locking slot 11211a enables the first half-shell 1121 and the second half-shell 1122 to mate, thus connecting the first half-shell 1121 and the second half-shell 1122. When it is necessary to disconnect the first half-shell 1121 and the second half-shell 1122, simply remove the locking block 11221 from the locking slot 11211a. This is simple and convenient, increasing the ease of assembly for the first half-shell 1121 and the second half-shell 1122. Furthermore, the mating of the first locking structure 11211 and the second locking structure can be concealed within the receiving space 11a, reducing mating marks on the exterior of the housing 112.

[0065] In some embodiments, please refer to Figure 6 The locking block 11221 has a guide slope 11221a. The guide slope 11221a extends downward along the first direction and away from the second half shell 1122. The end of the locking block 11221 away from the guide slope 11221a has an abutment surface 11221b. The abutment surface 11221b abuts against the groove wall of the slot 11211a on the side close to the second half shell 1122.

[0066] Specifically, the guide slope 11221a serves a guiding function. When the first locking structure 11211 contacts the locking block 11221, the guide slope 11221a guides the locking block 11221 to slide into the locking slot 11211a along the correct path. When the locking block 11221 is fully inside the locking slot 11211a, the abutting surface 11221b of the locking block 11221 abuts against the side of the locking slot 11211a closest to the second half-shell 1122, thereby confining the locking block 11221 within the locking slot 11211a, reducing the probability of the locking block 11221 dislodging from the locking slot 11211a, and increasing the docking stability of the first half-shell 1121 and the second half-shell 1122. Simultaneously, the inclined design of the guide slope 11221a also reduces frictional wear generated during the contact between the locking block 11221 and the locking slot 11211a.

[0067] In some embodiments, please refer to Figure 3 and Figure 5 The hair curler 1 includes a circuit board 14, which is disposed within the receiving space 11a and is electrically connected to the drive module 12.

[0068] Specifically, the circuit board 14 can serve as the control structure of the curling iron 1, providing power and signal transmission to the drive module 12 so that the drive module 12 can operate according to a predetermined program and drive the curling assembly 10 to rotate.

[0069] Of course, the circuit board 14 can also be electrically connected to the heating element 17 to adjust the heating temperature and heating power of the heating element 17. At the same time, the circuit board 14 can also have functions such as timing.

[0070] In this embodiment, the circuit board 14 is disposed within the accommodating space 11a. The accommodating space 11a provides mounting space for the circuit board 14. On the one hand, this makes the overall structure of the curling iron 1 more compact, eliminating the need to set up an additional mounting area for the circuit board 14. On the other hand, since both the circuit board 14 and the drive module 12 are disposed within the accommodating space 11a, it is convenient to realize the electrical connection between the circuit board 14 and the drive module 12, reducing the distance between the circuit board 14 and the drive module 12.

[0071] In some embodiments, please refer to Figure 2 and Figure 3 The hair curler 1 includes a heating element 17, and a portion of the hair curling assembly 10 is disposed around the outer periphery of the heating element 17 and is rotatable relative to the heating element 17.

[0072] The curling iron 1 includes a cable, and the heating element 17 and the circuit board 14 are connected by a conductive path through the cable so that the circuit board 14 can provide power to the heating element 17.

[0073] Specifically, the heating element 17 is used to generate heat, and the curling iron 1 irons the hair through the heating element 17. During the curling process, the drive module 12 applies a driving force to the curling component 10, and the curling component 10 rotates around the hair along the circumference of the heating element 17, so that the heating element 17 irons the hair.

[0074] It should be noted that the heating element 17 and the circuit board 14 establish a conductive path through a cable. This can be achieved by either having no intermediate components in the electrical connection between the heating element 17 and the circuit board 14, with the cable directly connecting them, or by having intermediate components in the electrical connection. For example, the curling iron 1 includes an adapter plate that connects the circuit board 14 and the heating element 17. Here, the adapter plate can be located at one end of the housing 112 axially near the curling assembly 10. Part of the adapter plate passes through the receiving space 11a to establish an electrical connection with the circuit board 14, while another part protrudes axially from the housing 112 to establish an electrical connection with the heating element 17. This increases the convenience of electrical connection for the curling iron 1 and shortens the wiring length. The adapter plate can also be equipped with contact springs to achieve electrical connection with the cable and the heating element 17.

[0075] In this embodiment, the hair is ironed by the heating element 17, and the circuit board 14 provides power to the heating element 17 through a cable. The arrangement of the heating element 17, the circuit board 14 and the hair curling assembly 10 makes the structure of the hair curler 1 compact and facilitates the connection between the modules.

[0076] In some embodiments, please refer to Figure 5 The circuit board 14 includes a first extension region 14a and a second extension region 14b along the axial direction of the curling iron 1. The second extension region 14b is located at the end of the first extension region 14a away from the heating element 17. The signal circuit of the circuit board 14 is located in the first extension region 14a, and the connection position between the drive module 12 and the circuit board 14 is located in the first extension region 14a.

[0077] Specifically, the signal circuit of the circuit board 14 realizes the reception, transmission and processing of signals. For example, the signal circuit of the circuit board 14 can obtain the position signal of the hair curling component 10 and control the drive module 12 to drive the hair curling component 10 to rotate accordingly based on the position signal.

[0078] The signal circuit of circuit board 14 can be electrically connected to the detection module used to detect the position signal of the hair curling assembly 10 via signal lines.

[0079] The connection between the drive module 12 and the circuit board 14 is located in the first extension area 14a. That is, the drive module 12 is located at one end of the circuit board 14 near the curling component 10. This facilitates the drive connection between the drive module 12 and the curling component 10, and also makes it easier for the signal circuit of the circuit board 14 to obtain the working signal of the drive module 12.

[0080] In some embodiments, the connection point between the cable and the circuit board 14 is located in the first extension region 14a.

[0081] It is understood that the cable and the circuit board 14 can be connected by soldering. Here, the connection position of the cable and the circuit board 14 is located in the first extension area 14a. That is to say, the connection position of the cable and the circuit board 14 is located on the side of the circuit board 14 close to the heating element 17. In this way, it is easy to shorten the wiring length between the cable and the circuit board 14. Furthermore, the electrical connection between the circuit board 14 and the heating element 17 can be achieved by combining the cable with the electrical contact spring, so as to further shorten the wiring length.

[0082] In other embodiments, the connection point between the cable and the circuit board 14 is located in the second extension region 14b.

[0083] In other words, in this embodiment, the connection point between the cable and the circuit board 14 is located on the side of the circuit board 14 away from the heating element 17.

[0084] It is understandable that, in order to reduce signal interference between components of the circuit board 14, the low-voltage module of the circuit board 14 can be set in one area and the high-voltage module of the circuit board 14 can be set in another area. Specifically, in this embodiment, the signal circuit is a low-voltage circuit, the first extension area 14a can be the low-voltage area of ​​the circuit board 14, the circuit for power supply is a high-voltage circuit, and the second extension area 14b can be the high-voltage area of ​​the circuit board 14. In this way, the interference between components of the circuit board 14 is small and the working reliability is high.

[0085] In this embodiment, the connection point between the cable and the circuit board 14 is located in the second extension area 14b, which makes it easy to set the low-voltage module and the high-voltage module of the circuit board 14 in different areas. The low-voltage module is set in the second extension area 14b, and the cable is connected from the second extension area 14b to supply power to the heating element 17.

[0086] In some embodiments, the curling iron 1 includes a power receiving module, at least partially disposed within a receiving space 11a, the power receiving module being electrically connected to a circuit board 14 for providing power to the circuit board 14.

[0087] In this embodiment, the power module can provide power to the circuit board 14 when the hair curler 1 is not connected to the power supply, so as to realize the hair curling operation of the hair curler 1, increase the ease of operation of the hair curler 1, and allow users to curl hair at any angle without the need for winding.

[0088] In some embodiments, please refer to Figure 3 and Figure 4 In a plane projection perpendicular to the first direction, at least a portion of the projection of the drive module 12 falls within the projection range of the circuit board 14, and the projection of the power-connecting module is located on the side of the circuit board 14 away from the drive module 12 along the axial direction, wherein the first direction is perpendicular to the axial direction of the curling iron 1.

[0089] In this embodiment, at least a portion of the projection of the drive module 12 falls within the projection range of the circuit board 14. This means that at least a portion of the drive module 12 and the circuit board 14 are stacked together along the first direction. The power connection module is located at one axial end of the circuit board 14. On the one hand, the accommodating space 11a can be fully utilized, increasing the rationality of the layout and reducing the axial size of the handle assembly 11. On the other hand, there is no interference between the power connection module and the drive module 12. Furthermore, the distance between the circuit board 14 and the power connection module, as well as the distance between the circuit board 14 and the drive module 12, is small, which facilitates electrical connection. This increases the compactness and rationality of the component layout of the curling iron 1 and achieves reliable electrical connection.

[0090] In some embodiments, please refer to Figure 1 and Figure 5 The handle assembly 11 also includes an outer cylinder 111, which is fitted around the outer periphery of the housing 112 and is an integral structure.

[0091] It is understandable that the outer tube 111 is fitted around the outer periphery of the housing 112, meaning that the housing 112 is not visible from the outside, and the outer tube 111 is an external component of the hair curler 1.

[0092] Understandably, the outer tube 111 is fitted around the outer periphery of the housing 112 and does not participate in the formation of the receiving space 11a. In this case, the outer tube 111 only needs to cooperate with the housing 112, without needing to consider the cooperation with the components inside the receiving space 11a. Furthermore, this reduces the manufacturing requirements of the outer tube 111. The double-layer structure can provide better mechanical strength and rigidity for the handle assembly 11, further protecting the components inside the receiving space 11a. At the same time, it can hide the cooperation between the housing 112 and the components, or its own splicing marks, inside the outer tube 111, increasing the aesthetic appearance of the curling iron 1.

[0093] The outer tube 111 has a one-piece structure, meaning it is manufactured as a single piece. The one-piece outer tube 111 has no seams on its surface. As an external component of the curling iron 1, the seams of the handle assembly 11 are not visible from the outside, making the overall appearance of the curling iron 1 more harmonious and neat, thus enhancing its aesthetics. Furthermore, it also increases the overall strength of the handle assembly 11, and when the user holds the handle assembly 11, the contact with the outer tube 111 provides a comfortable grip and prevents scratches to the user's fingers.

[0094] For example, the outer cylinder 111 is generally a hollow columnar structure, and the shell 112 is disposed in the hollow space of the outer cylinder 111.

[0095] The material of the outer cylinder 111 is not limited; it can be made of plastic or metal. There are no restrictions here.

[0096] The docking method between the outer cylinder 111 and the shell 112 is not limited. The outer cylinder 111 and the shell 112 are manufactured separately. The outer cylinder 111 can be docked with the shell 112 by means of snap-fit ​​or other methods to reduce the installation marks on the surface of the outer cylinder 111.

[0097] The hair curler 1 provided in this embodiment of the application, by fitting the outer tube 111 over the outer shell 112, and with the outer tube 111 being a one-piece component without any splicing or installation marks, makes the overall appearance of the hair curler 1 more harmonious and neat, facilitating the user's handheld hair curling operation and reducing the risk of scratching the user. At the same time, the cooperation between the outer tube 111 and the shell 112 also increases the structural strength of the hair curler 1. The double-layer structure further protects the components within the accommodating space 11a, increasing the structural reliability of the handle assembly 11.

[0098] Specifically, when the outer cylinder 111 and the shell 112 are docked, the outer cylinder 111 can gradually cover the shell 112 along the axial direction so that the shell 112 is surrounded inside the outer cylinder 111.

[0099] In some embodiments, the first half-shell 1121 and / or the second half-shell 1122 are provided with a first anti-rotation structure, and the outer cylinder 111 is provided with a second anti-rotation structure. The first anti-rotation structure and the second anti-rotation structure cooperate to achieve an anti-rotation fit between the outer cylinder 111 and the shell 112 in the circumferential direction.

[0100] It should be noted that the circumferential anti-rotation fit between the outer cylinder 111 and the housing 112 means that when the drive module 12 located in the receiving space 11a drives the hair curling component 10 to rotate, the outer cylinder 111 and the housing 112 do not rotate relative to each other, and the outer cylinder 111 and the housing 112 remain stationary relative to the drive module 12 and the hair curling component 10.

[0101] Specifically, the first anti-rotation structure is disposed on the first half shell 1121 and / or the second half shell 1122, and the second anti-rotation structure is disposed on the outer cylinder 111, corresponding to the first anti-rotation structure. When the outer cylinder 111 is connected to the shell 112, the first anti-rotation structure and the second anti-rotation structure cooperate with each other so that when the drive module 12 drives the hair curling assembly 10 to rotate, the outer cylinder 111 and the shell 112 do not rotate relative to each other.

[0102] In this embodiment, when the drive module 12 drives the curling assembly 10 to rotate, unnecessary relative rotation will not occur between the outer tube 111 and the housing 112, increasing the positioning reliability of the outer tube 111 and the housing 112, increasing the overall structural reliability of the handle assembly 11, and making it easier for the user to hold the handle assembly 11. The housing 112 and the outer tube 111 are correspondingly engaged by the first anti-rotation structure and the second anti-rotation structure, without the need for additional fixing measures. When it is necessary to disassemble the housing 112 and the outer tube 111, the locking and unlocking of the first anti-rotation structure and the second anti-rotation structure is also relatively convenient.

[0103] The specific construction of the first anti-rotation structure and the second anti-rotation structure is not limited. The first anti-rotation structure can be a protrusion, a groove or other form of mechanical limiting structure provided on the housing 112, and the second anti-rotation structure can be a groove, a protrusion or other form of mechanical limiting structure provided on the outer cylinder 111.

[0104] For example, in some embodiments, please refer to Figure 5 The first anti-rotation structure includes at least one notch 112a formed on the outer peripheral surface of the first half shell 1121 and / or the second half shell 1122, and the second anti-rotation structure includes at least one protrusion 1111 formed on the inner wall surface of the outer cylinder 111, the protrusion 1111 being inserted into the notch 112a.

[0105] In this embodiment, the outer cylinder 111 and the shell 112 are anti-rotationally engaged in the circumferential direction by the cooperation of the notch 112a and the protrusion 1111. The structure of the notch 112a and the protrusion 1111 is simple. While ensuring that the outer cylinder 111 and the shell 112 will not rotate or shift due to external forces, the outer cylinder 111 and the shell 112 can also be circumferentially positioned, increasing the working accuracy and stability of the handle assembly 11.

[0106] In some embodiments, please refer to Figure 5 The first anti-rotation structure also includes a stop structure 112b protruding from the outer peripheral surface of the first half-shell 1121 and / or the second half-shell 1122. The stop structure 112b is used to make axial stop contact with the protrusion 1111 when the protrusion 1111 is inserted into the notch 112a.

[0107] In this embodiment, the stop structure 112b can contact the protrusion 1111 along the axial stop, which further reduces the probability of rotational displacement between the outer cylinder 111 and the shell 112, while limiting the outer cylinder 111 and the shell 112 along the axial direction, thereby increasing the docking reliability between the outer cylinder 111 and the shell 112.

[0108] In some embodiments, please refer to Figure 1 and Figure 5 The handle assembly 11 has a mounting opening 11b, and the curling iron 1 includes at least one button structure 13. The button structure 13 passes through the mounting opening 11b and is exposed on the outer surface of the handle assembly 11.

[0109] It is understandable that the number of button structures 13 can be one, two, or more. Button structures 13 can be used to turn the curling iron 1 on and off and adjust its power.

[0110] It should be noted that the button structure 13 is exposed on the outer surface of the handle assembly 11, meaning that the button structure 13 is visible from the outside, so that the user can use the button structure 13 to perform the corresponding functions of the curling iron 1 when holding the handle assembly 11. The button structure 13 can be flush with the outer surface of the handle assembly 11, protrude from the outer surface of the handle assembly 11, or be recessed into the outer surface of the handle assembly 11; there is no limitation on this.

[0111] The installation port 11b can be set in any location.

[0112] In some embodiments, please refer to Figure 5 The mounting port 11b is provided in the outer cylinder 111 and the housing 112. This allows the button structure 13 to pass through the outer cylinder 111 and the housing 112 to cooperate with the circuit board 14 and be exposed on the outer surface of the outer cylinder 111. In this embodiment, the mounting port 11b being located in the outer cylinder 111 and the housing 112 increases the stability of the button structure 13, and the outer cylinder 111 and the housing 112 can jointly limit the movement of the button structure 13.

[0113] In some embodiments, please refer to Figure 1 and Figure 5 The number of mounting ports 11b is at least two, the number of button structures 13 is at least two, the at least two button structures 13 are arranged at intervals along the axial direction of the hair curler 1, at least one button structure 13 is used to open or close the hair curler 1, and at least another button structure 13 is used to adjust the power of the hair curler 1.

[0114] It is understandable that the arrangement of at least two button structures 13 along the axial direction of the curling iron 1 means that there is a gap between the at least two button structures 13 along the axial direction of the curling iron 1. This reduces the chance of accidental touch and increases operational reliability.

[0115] At least one other button structure 13 is used to adjust the power of the curling iron 1, which may be heating power adjustment, to achieve different curling effects.

[0116] In some embodiments, please refer to Figure 1 and Figure 2 The hair curler 1 includes a housing 16, which is fitted around the outer periphery of the hair curling component 10. The housing 16 has at least one opening slot 16a for hair to enter. One side end face of the housing 16 along the axial direction abuts against the outer cylinder 111.

[0117] Specifically, the opening slot 16a allows hair to enter so that the hair curling component 10 can perform hair curling operations. Part of the hair curling component 10 is surrounded by the heating element 17. The outer shell 16 can reduce the chance of the user accidentally contacting the heating element 17 while allowing hair to enter, thus providing a scalding protection effect.

[0118] For example, the housing 16 may be made of a heat-resistant material.

[0119] The outer shell 16 abuts against the outer cylinder 111 on one side along the axial direction. That is, the outer shell 16 contacts the outer cylinder 111 on one side along the axial direction, which reduces the probability of the components of the hair curler 1 being exposed or detached at the docking position of the outer shell 16 and the outer cylinder 111, and increases the structural stability of the hair curler 1.

[0120] It is understandable that the axial end face of the outer shell 16 abuts against the outer tube 111. This could mean that the axial end face of the outer shell 16 contacts the axial end face of the outer tube 111 near the curling assembly 10, in which case there is no connection between the outer tube 111 and the outer shell 16. Alternatively, the axial end face of the outer shell 16 can be engaged with the outer tube 111 (see [link to relevant documentation]). Figure 4 At this time, there is a connection between the outer cylinder 111 and the outer shell 16.

[0121] For example, in some embodiments, please refer to Figure 4 and Figure 5 The outer cylinder 111 has a first contraction section 1112 formed on the side near the outer shell 16. The outer shell 16 includes a first shaft section 161 and a second shaft section 162. The inner diameter of the first shaft section 161 is larger than the inner diameter of the second shaft section 162. A first end face 16b is formed at the junction of the two. The first contraction section 1112 is inserted into the first shaft section 161 and abuts against the first end face 16b.

[0122] In this embodiment, the outer cylinder 111 and the outer shell 16 are connected by the cooperation of the first contraction section 1112 and the first end face 16b, thereby limiting the outer cylinder 111 and the outer shell 16, increasing the connection stability between the two, reducing the probability of axial displacement of the outer shell 16 or the outer cylinder 111, and increasing the structural stability of the hair curler 1.
