Description

Technical Field

[0001] This invention relates to the field of hair styling appliance technology, specifically to a curling iron with a detachable structure, which enables convenient replacement of the curling iron's head. Background Technology

[0002] In the current hair styling tool market, traditional curling irons typically have fixed, non-removable heads. This is extremely inconvenient when the curling iron head is damaged or when users want to change to different sizes or shapes of curling heads, requiring the entire curling iron to be replaced, resulting in resource waste and increased costs. Utility Model Content

[0003] The purpose of this utility model is to overcome the defects of the prior art by providing a hair curler with a detachable head, which solves the problem that the head of the existing curling iron is not detachable or the detachable structure is prone to failure, making it convenient for users to replace the head and improving the practicality and service life of the product.

[0004] The technical solution of this utility model: a hair curling iron with a detachable head, comprising:

[0005] handle part;

[0006] The detachable head has a heated hair-curling section, and the hair-curling section is connected to the control circuit module of the handle via a detachable electrical connection.

[0007] The locking mechanism is used to lock or unlock the connection between the head and the handle.

[0008] By adopting the above technical solution, the detachable structure is easy to install, and users can easily replace the head without the need for additional tools. The locking mechanism is ingeniously designed, allowing for quick locking or unlocking of the head and handle through simple operation, facilitating head replacement and improving user convenience; and when the head is locked, the curling section and handle are connected by a detachable electrical connection, allowing the handle to supply power and heat the curling section.

[0009] A further feature of this invention is that the locking mechanism includes a locking element and a locking groove. The handle is provided with the locking element or the locking groove, and the head is provided with a corresponding locking groove or locking element. The latch of the locking element can move in and out of the locking groove, thereby locking or unlocking the head.

[0010] With the aforementioned further design, a stable locking state is achieved when the latch is inserted into the lock slot, preventing the head from accidentally falling off. To unlock, the user simply applies external force to disengage the latch from the lock slot, separating the head from the handle. This locking and unlocking method is simple to operate, requiring no complicated steps, and greatly improves the user experience.

[0011] A further feature of this invention is that the middle part of the lock is hinged to the handle or head, one end of the lock is a pressing operation part and the other end is a latch part, and the lock assembly mechanism is also provided with an elastic element and a button that can act on the lock.

[0012] When the button is pressed, the pressing operation part is subjected to force, which causes the lock to rotate around the hinge point, thereby causing the latch to move outward to disengage from the lock groove;

[0013] After the button is released, the lock is rotated and reset by the elastic element, which in turn drives the latch to move inward and insert into the lock groove.

[0014] With the above-described further design, an elastic element, such as a spring, is used to drive the latch to automatically engage with the lock slot, thus locking the head and handle. When the user needs to unlock, simply apply a certain external force to the pressing operation part of the lock to allow the latch to overcome the elastic force of the elastic element and exit the lock slot, easily removing the head.

[0015] A further improvement of this utility model is that it has two sets of locking mechanisms, which are arranged symmetrically.

[0016] With the above-mentioned further design, the stability of the head is improved during use, effectively preventing the head from accidentally falling off or loosening. In addition, the symmetrical locking mechanism design makes it easier for users to disassemble the head. For example, the head can be easily released by simply pressing the buttons on both sides at the same time.

[0017] A further feature of this invention is that the head also includes a curling claw, which is rotatably mounted on the periphery of the perming section. The handle has a power drive device that can drive the curling claw to rotate. The curling claw is connected to the output of the power drive device through a detachable structure. The locking mechanism is used to lock or unlock the curling claw of the head, and the locking groove therein has a ring structure.

[0018] With the aforementioned further configuration, the power drive device not only enables the automatic rotation of the curling claw, increasing the efficiency and effect of curling, but also, through its detachable plug-in structure, allows the curling claw to be easily installed or removed as needed. Furthermore, the annular locking groove design ensures that the curling claw is stably locked by the locking mechanism at any rotational position, facilitating the rotational operation of the curling claw.

[0019] A further feature of this invention is that the curling claw and the output of the power drive device are connected via a plug-in structure to achieve synchronous rotation; the hair-curling part and the control circuit module are connected via a plug-in structure.

[0020] With the aforementioned further design, the curling claws can easily connect to the output end of the power drive device via a plug-in structure, achieving rapid and reliable synchronous rotation. Simultaneously, the plug-in connection between the curling section and the control circuit module greatly simplifies the circuit connections of the curling iron, making the assembly and disassembly of the entire curling iron more convenient.

[0021] A further feature of this invention is as follows: the power drive device includes a motor, a gear, and a rotating gear sleeve, wherein the gear and the rotating gear sleeve are rotatably mounted inside the handle. The gear is connected to the output shaft of the motor for transmission. The rotating gear sleeve has internal teeth on its inner circumference. The gear is offset from the center of the rotating gear sleeve and meshes with its internal teeth. The curling claw is directly or indirectly inserted into the rotating gear sleeve and rotates synchronously through key teeth and grooves. The hair-curling part is electrically connected to the control circuit module through a male and female connector.

[0022] With the further configuration described above, since the rotating gear sleeve and the curling claw are directly or indirectly connected, and the curling claw is equipped with key teeth, while the rotating gear sleeve has tooth grooves that match the key teeth, the rotating gear sleeve can drive the curling claw to rotate synchronously when it rotates. This structure not only realizes the automatic rotation function of the curling claw, but also ensures the stability and reliability of the rotation through gear transmission. Furthermore, the gear is offset from the center of the rotating gear sleeve, making it easier to provide space for the middle curling section and the handle to connect. The plug-in electrical connection between the male and female heads not only ensures a stable electrical connection between the curling section and the control circuit module, but also allows the curling section to be easily plugged into and unplugged from the control circuit module, thus realizing the detachable head function of the hair curler.

[0023] A further feature of this invention is that the head has a mounting base, wherein the curling claw and the lower end of the perming part are mounted on the mounting base, and the perming part is rotatably engaged with the mounting base. The mounting base and the rotating gear sleeve are plugged into each other. The mounting base is provided with key teeth or grooves, and the rotating gear sleeve is provided with corresponding grooves or key teeth. The locking element is located on the upper part of the handle, and the locking groove is located on the outer periphery of the mounting base. The male head and the female head are respectively located at the center of the mounting base and the rotating gear sleeve.

[0024] This further design, with the mounting bracket serving as a key component connecting the curling claw and the perming section, not only ensures stable assembly of both but also guarantees the stability and synchronization of the perming section during rotation through its insertion into the rotating gear sleeve and the engagement of the key teeth and grooves. Furthermore, the locking groove on the mounting bracket engages with the locking mechanism on the upper part of the handle, allowing for convenient assembly and disassembly of the perm head. The inclusion of both female and male connectors ensures stable current transmission during operation, enhancing safety and reliability.

[0025] A further feature of this invention is as follows: a mounting bracket is provided in the handle portion, the motor and the female head are mounted on the mounting bracket, with the female head mounted on the upper end of the mounting bracket, the gear is mounted on the output shaft at the upper end of the motor, the mounting bracket has an opening structure for the gear to be exposed, and the rotating gear sleeve is fitted over the upper end of the mounting bracket and meshes with the exposed gear.

[0026] With the above-described further configuration, the motor is securely mounted on the mounting bracket, and the female connector is also located at the upper end of the mounting bracket. This layout is not only compact but also ensures the stability of the motor and the female connector. The gear, as a transmission component, is mounted on the motor's output shaft and can mesh with the rotating gear sleeve through the opening structure of the mounting bracket. This design makes the rotation operation of the perming section smoother and more precise. Attached Figure Description

[0035] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] like Figure 1-8 As shown, this utility model discloses a detachable head hair curler, comprising:

[0037] The handle part 1 has a control circuit module 11, a power supply 12 and a power drive device 13, and the power drive device 13 and the power supply 12 are both connected to the control circuit module 11.

[0038] The detachable head 2 has a heated hair-curling part 21, which is connected to the control circuit module 11 of the handle part 1 by a separable electrical connection. Specifically, the heating element built into the hair-curling part 21 is electrically connected to the control circuit module 11, and the heating element is powered by a power source. The control circuit module is a circuit board.

[0039] A locking mechanism 3 is used to lock or unlock the connection between the head 2 and the handle 1. The locking mechanism 3 includes a locking element 31 and a locking groove 32. The handle 1 is provided with the locking element 31 or the locking groove 32, and the head 2 is provided with a corresponding locking groove 32 or the locking element 31. The latch 311 of the locking element 31 can move in and out of the locking groove 32, thereby locking or unlocking the head 2. The locking element 31 is hinged to the handle 1 or the head 2 at its middle. One end of the locking element 31 is a pressing operation part 312, and the other end is a latch 311. The locking mechanism 3 also includes an elastic element 33 and a button 34 that can act on the locking element 31. The elastic element is preferably a spring, with one end abutting against the outer shell of the handle and the other end abutting against the outer end face of the latch 311. The button 34 abuts against the outer end face of the pressing operation part 312 and is also exposed. The elastic element can also be a tension spring that acts on the pressing operation part 312.

[0040] When button 34 is pressed, the pressing operation part 312 is forced to rotate the locking part 31 around the hinge point, which in turn drives the latch part 311 to move outward to exit the lock groove 32. At this time, the latch part 311 compresses the spring outward.

[0041] After the button 34 is released, the locking element 31 is driven by the elastic element 33 to rotate and reset, thereby driving the latch 311 to move inward and insert into the locking groove 32.

[0042] The locking element 31 can also be a sliding type.

[0043] This utility model has two sets of locking mechanisms 3, which are symmetrically arranged. Each locking mechanism includes the aforementioned locking element 31, locking groove 32, elastic element 33, and button 34. The two sets of locking mechanisms 3 act on both sides of the head 2, thereby ensuring a stable lock between the head 2 and the handle 1.

[0044] Specifically, the head 2 also includes a curling claw 22, which is rotatably mounted on the periphery of the perming section 21. The handle section 1 has a power drive device 13 that can drive the curling claw 22 to rotate. The output of the power drive device 13 is connected to the curling claw 22 via a detachable structure. The locking mechanism 3 is used to lock or unlock the curling claw of the head, and the locking groove 32 therein has a ring structure. The curling claw 22 and the output of the power drive device 13 cooperate through a plug-in structure and achieve synchronous rotation; the perming section 21 and the control circuit module 11 are connected to each other via a plug-in structure. The power drive device 13 includes a motor 131, a gear 132, and a rotating gear sleeve 133. The motor 131 is fixedly mounted inside the handle part 1. The gear 132 and the rotating gear sleeve 133 are rotatably mounted inside the handle part 1. The gear 132 is connected to the output shaft of the motor 131. The rotating gear sleeve 133 has internal teeth 1331 on its inner circumference. The gear 132 is offset from the center of the rotating gear sleeve 133 and meshes with its internal teeth 1331. The curling claw 22 is directly or indirectly inserted into the rotating gear sleeve 133 and rotates synchronously through key teeth 41 and tooth grooves 42. The hair-curling part 21 and the control circuit module 11 are electrically connected via a male connector 51 and a female connector 52. The male connector 51 is a pin structure, and the female connector is a socket structure. The hair-curling part 21 is provided with a male connector 51, and the control circuit module 11 is connected to the female connector 52, or the hair-curling part 21 is provided with a female connector 52, and the control circuit module 11 is connected to the male connector 51.

[0045] Specifically, the head 2 has a mounting base 23, wherein the lower ends of the curling claw 22 and the perming part 21 are disposed on the mounting base 23, and the perming part 21 is rotatably engaged with the mounting base 23. The curling claw 22 is fixedly or integrally disposed with the mounting base 23. The mounting base 23 is inserted into the rotating gear sleeve 133. The mounting base 23 is provided with key teeth 41 or grooves 42, and the rotating gear sleeve 133 is provided with corresponding grooves 42 or key teeth 41. The locking member 31 is disposed on the upper part of the handle part 1, and the locking groove 32 is disposed on the outer periphery of the mounting base 23. The male head 51 and the female head 52 are respectively located at the center of the mounting base 23 and the center of the rotating gear sleeve 133. Specifically, the female head 52 is located at the center of the mounting base 23, and the male head 51 is located at the center of the rotating gear sleeve 133; or the female head 52 is located at the center of the rotating gear sleeve 133, and the male head 51 is located at the center of the mounting base 23. The mounting base 23 is fitted over the upper part of the rotating gear sleeve. Multiple toothed grooves 42 are located on the outer periphery of the upper part of the rotating gear sleeve, and key teeth 41 are located on the inner periphery of the mounting base 23. The key teeth 41 and the toothed grooves 42 engage. The upper end of the latch 311 has a sloping push surface 3111. This design allows for quick insertion of the head. When the head is inserted downwards, it contacts the sloping push surface 3111. Guided by the sloping push surface 3111, the latch 311 is pushed outwards. As the head continues to be inserted, when the locking groove aligns with the latch 311, the latch 311 can be inserted inwards into the locking groove under the action of the elastic element 33. Alternatively, the latch 311 can be moved outwards by pressing a button. After the head is inserted in place, releasing the button allows the latch 311 to be inserted inwards into the locking groove.

[0046] Specifically, the handle portion 1 is provided with a mounting bracket 14, which can be mounted on the outer shell of the handle portion by screws or clips. The motor 131 and the female connector 52 are mounted on the mounting bracket 14, with the female connector 52 mounted on the upper end of the mounting bracket 14 (or it could be a male connector 51). The gear 132 is mounted on the output shaft at the upper end of the motor 131. The mounting bracket 14 has an opening structure for the gear 132 to be exposed. The rotating gear sleeve 133 is fitted over the upper end of the mounting bracket 14 and meshes with the exposed gear 132. The key teeth on the upper part of the rotating gear sleeve 133 and the female connector 52 are exposed at the upper end of the handle portion outer shell. The head is mounted on the upper end of the handle portion.

[0047] Among them, the separable electrical connection methods, in addition to the above-mentioned male and female plug-in mating method, can also be other separable structures such as magnetic connection, which uses the attraction of magnetic materials to make the two parts fit tightly together, and at the same time, the internal conductive contacts come into contact with each other under the action of magnetic force to form a conductive path.

[0048] The working principle of this utility model is as follows:

[0049] When the user installs the head 2, the latch 311 of the locking piece 31 is inserted into the locking groove 32 to achieve locking, and the locking mechanism 3 ensures a stable connection between the head 2 and the handle 1.

[0050] At this time, the hair-curling part 21 of the head 2 and the control circuit module 11 of the handle part 1 are electrically connected, and the curling claw and the power drive device of the handle part are connected by transmission. Specifically, the male head 51 of the hair-curling part 21 is inserted into the female head 52 on the handle part 1, so that the heating element in the hair-curling part 21 is electrically connected to the control circuit module 11, and the heating is turned on by the switch button. The built-in power supply or the external power supply provides the required power to the whole hair-curling machine. The mounting bracket 23 is inserted into the rotating gear sleeve 133, and the key tooth 41 and the tooth groove 42 are engaged to realize the synchronous rotation of the curling claw 22 and the rotating gear sleeve 133. After the motor 131 is started, its output shaft drives the gear 132 to rotate, and the gear 132 drives the rotating gear sleeve 133 to rotate, thereby driving the curling claw 22 to rotate around the outer circumference of the hair-curling part 21.

[0051] When it is necessary to replace the head 2, the user can press the button 34 to make the pressing operation part 312 drive the locking part 31 to rotate around the hinge point, thereby driving the latch part 311 to exit the locking groove 32. At this time, the lock between the curling claw 22 of the head and the handle part 1 is released, and the user can easily disassemble the head 2, separate the male head 51 and the female head 52, and separate the mounting base 23 from the rotating toothed sleeve 133.
