Description
Technical Field
[0001] This utility model belongs to the field of hair straightening comb technology, specifically relating to a hair straightening and curling tool. Background Technology
[0002] As a core tool for daily hair care, hair straighteners combine high-temperature heating with negative ion technology to achieve straight, curly, and smooth hair styling. With consumers' increasing demand for convenient styling and healthy hair care, existing hair straighteners generally integrate comb teeth and combing structure, which can not only comb hair to reduce static electricity, but also be used with hot air or electric heating elements for styling. Traditional designs typically employ a one-piece or screw-fixed structure, requiring tools to disassemble the outer shell to access internal components. This leads to frequent, time-consuming, and laborious cleaning operations, causing most users to reduce their cleaning frequency. Ultimately, this results in problems such as the accumulation of chemical residues and bacterial growth, which may cause scalp sensitivity or hair follicle damage. Utility Model Content
[0003] In view of this, the present invention provides a hair straightener / curler that can achieve a balance between quick disassembly and stable locking through a rotating plug-linked multi-positioning structure. This allows the comb teeth and bristles to be quickly exposed to the outside for rinsing or replacement, avoiding damage to hair follicles caused by the accumulation of chemical residues. The snap-fit positioning structure ensures that the stability is not reduced after assembly, improving the ease of operation and product durability.
[0004] To solve the above-mentioned technical problems, this utility model provides a hair straightener and curling iron, including a handle and a negative ion generator disposed therein. The upper part of the outer arc surface of the handle is provided with a plurality of evenly distributed comb bristles. The upper side of the handle is provided with a quick-release assembly, which includes two outer shells symmetrically placed in the groove at the upper end of the handle. The two outer shells form a circular tubular structure. The outer arc surface of each outer shell is provided with evenly distributed openings. The comb bristles pass through the corresponding openings and extend to the outside. The upper end of the handle is threadedly connected to a plug. The upper ends of the two outer shells are located in the plug. The comb teeth are movably inserted into the slots provided in the middle of the outer arc surface of the outer shells. A limiting component is also provided between the handle and the plug to limit the two outer shells. That is, by rotating the plug and linking multiple limiting structures, a balance between quick disassembly and stable locking is achieved, so that the comb teeth and comb bristles can be quickly exposed to the outside for rinsing or replacement, avoiding damage to hair follicles caused by the accumulation of chemical residues. Moreover, the snap-fit limiting structure ensures that the stability is not reduced after assembly, improving the convenience of operation and the durability of the product. The outer edge of the upper end of the outer shell, the outer edge of the upper end of the comb teeth, and the inner edge of the lower end of the plug are all inclined downward from the inside to the outside, which ensures the stable positioning of the outer shell.
[0005] One of the outer shells has several evenly distributed limiting posts on both sides, and the other outer shell has limiting holes on both sides that are adapted to each limiting post, thus achieving initial limiting and locking of the outer shells.
[0006] The limiting component includes a limiting seat located on the upper end of the inner arc surface of the handle. The bottom wall of the limiting seat is flush with the bottom wall of the groove. Limiting plates are provided in the middle of the inner arc surfaces of the two outer shells. The lower ends of the limiting plates are movably inserted into the inner cavities of the adjacent limiting seats on the same side, thereby ensuring the stability of the outer shells during use.
[0007] The limiting assembly also includes protrusions respectively disposed on the bottom wall of the limiting seat. The protrusions are movably inserted into the lower opening of the limiting insert plate located in the same limiting seat, thereby realizing the positioning of the limiting insert plate and its accessories.
[0008] The limiting component also includes a limiting ring located at the lower middle of the plug. The limiting ring abuts against two limiting plates through a flexible component, thereby limiting the limiting plates.
[0009] The flexible component includes an annular pad disposed on the outer arc surface of the limiting ring, and both limiting plates abut against the annular pad, which can utilize the flexible characteristics to generate deformation to avoid collision.
[0010] Rotating beads are rotatably connected to the outer corner of the upper end of the outer shell and the outer corner of the upper end of the comb teeth. The rotating beads roll into contact with the lower end of the inner arc surface of the plug, thereby reducing the friction coefficient during disassembly and assembly.
[0011] The beneficial effects of the above-mentioned technical solution of this utility model are as follows: 1. When cleaning the comb bristles and teeth, the user should first rotate the threaded plug counterclockwise to release the pressure exerted by the plug and limiting components on the outer casing. Then, gently pull the outer casing upwards to disengage it from the limiting components. Next, symmetrically pry open the outer casings outwards. This will separate the limiting posts on both sides of the outer casing from the limiting holes of the symmetrical outer casings, exposing the internal comb bristles. The user can then further remove the comb teeth that are movably inserted into the slots to rinse or replace the components. During assembly, first insert the comb teeth one by one into the slots on the outer curved surface of the outer casing, then pass the comb bristles through the opening in the outer casing, push the outer casing along the groove at the top of the handle, and then fasten the clips. Assemble the two outer shells, ensuring the limiting post precisely engages with the limiting hole on the other outer shell. Finally, tighten the plug clockwise. The inclined surface of its lower inner wall will press against the inclined edges of the outer shell and comb teeth, mechanically pressing the two outer shells together. At the same time, the limiting components form a snap-lock. This design achieves a balance between quick disassembly and stable locking through the rotation of the plug and the linkage of multiple limiting structures. This allows the comb teeth and comb bristles to be quickly exposed to the outside for rinsing or replacement, avoiding damage to hair follicles caused by the accumulation of chemical residues. The snap-locking structure ensures that the stability is not reduced after assembly, improving operational convenience and product durability.
[0012] 2. Align the limiting plate with the limiting seat and slide it in. Then, snap the two outer shells together, ensuring that the limiting post is precisely inserted into the limiting hole on the other outer shell. Finally, tighten the plug clockwise. The inclined surface of its lower inner wall will press against the inclined edges of the outer shell and the comb teeth. Through mechanical compression, the two outer shells will be fastened together. At the same time, the elastic force generated by the deformation of the annular pad and the limiting plate will form a buckle lock, ensuring that the stability after assembly is not reduced, improving the ease of operation and product durability.
[0013] 3. The rotating balls on the outer side of the outer shell and comb teeth roll along the inner wall of the plug, reducing friction during disassembly and assembly. Attached Figure Description

Detailed Implementation
[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.
[0017] This embodiment provides a hair straightener / curling iron, such as... Figure 1-5As shown: The device includes a handle 100 and a negative ion generator 200 disposed therein. The upper part of the outer arc surface of the handle 100 has a plurality of evenly distributed comb-like bristles 201. A quick-release assembly is provided on the upper side of the handle 100. The quick-release assembly includes two outer shells 300 symmetrically placed in the groove at the upper end of the handle 100. The two outer shells 300 form a circular tubular structure. Evenly distributed openings are provided on the outer arc surface of each outer shell 300. The comb-like bristles pass through the corresponding openings and extend to the outside. A plug 301 is threadedly connected to the upper end of the handle 100. The upper parts of the two outer shells 300... All ends are located inside the plug 301. The comb teeth 302 are movably inserted into the slots provided in the middle of the outer arc surface of the outer shell 300. A limiting component for limiting the two outer shells 300 is also provided between the handle 100 and the plug 301. The outer edge of the upper end of the outer shell 300, the outer edge of the upper end of the comb teeth 302, and the inner edge of the lower end of the plug 301 are all inclined downward from the inside out. Several limiting posts 303 are evenly distributed on both sides of one outer shell 300, and limiting holes that are adapted to each limiting post 303 are provided on both sides of the other outer shell 300.
[0018] The negative ion generator 200 inside the handle 100 releases negative ions synchronously through the comb 201 and comb teeth 302 to achieve smooth styling of the hair. This technology is a common technique in this field and is not innovative here. When it is necessary to clean the comb 201 and comb teeth 302, the user first rotates the threaded plug 301 counterclockwise to release the pressure of the plug 301 and the limiting component on the outer shell 300. At this time, gently pull the outer shell 300 upward to separate the two outer shells 300 from the limiting component. Then, symmetrically open the outer shells 300 outward. At this time, the limiting posts 303 on both sides of the outer shell 300 will separate from the limiting holes of the symmetrical outer shells 300, exposing the internal comb 201. The user can then pull out the comb teeth 302 that are movably inserted into the slots to rinse or replace the components. During assembly, first insert the comb teeth 302 one by one into the outer shell. The slot on the outer arc surface of the shell 300 is used to insert the comb 201 through the opening in the shell 300. The shell 300 is then pushed in along the groove at the upper end of the handle 100. The two shells 300 are then fastened together, ensuring that the limiting post 303 is precisely inserted into the limiting hole of the other shell 300. Finally, the plug 301 is tightened clockwise. The inclined surface of its lower inner wall will press against the inclined edges of the shell 300 and the comb teeth 302. Through mechanical compression, the two shells 300 are fastened together, and the limiting components form a snap-lock. This design achieves a balance between quick disassembly and stable locking by rotating the plug 301 in conjunction with multiple limiting structures. This allows the comb teeth 302 and comb 201 to be quickly exposed to the outside for rinsing or replacement, avoiding damage to the hair follicles caused by the accumulation of chemical residues. The snap-locking structure ensures that the stability is not reduced after assembly, improving the ease of operation and product durability.
[0019] like Figure 2-5As shown, the limiting assembly includes a limiting seat 400 disposed on the upper end of the inner arc surface of the handle 100. The bottom wall surface of the limiting seat 400 is flush with the bottom wall surface of the groove. The inner arc surfaces of the two outer shells 300 are each provided with a limiting insert plate 401. The lower end of the limiting insert plate 401 is movably inserted into the inner cavity of the adjacent limiting seat 400 on the same side. The limiting assembly also includes protrusions 402 disposed on the bottom wall surface of the limiting seat 400. The protrusions 402 are movably inserted into the lower opening of the limiting insert plate 401 located in the same limiting seat 400. The limiting assembly also includes a limiting ring 403 disposed at the lower middle part of the plug 301. The limiting ring 403 abuts against the two limiting insert plates 401 through a flexible member. The flexible member includes an annular pad 404 disposed on the outer arc surface of the limiting ring 403. Both limiting insert plates 401 abut against the annular pad 404.
[0020] The limiting plate 401 slides into the limiting seat 400, and then the two outer shells 300 are fastened together to ensure that the limiting post 303 is accurately inserted into the limiting hole of the other outer shell 300. Finally, the plug 301 is tightened clockwise. The inclined surface of its lower inner wall will press against the inclined edges of the outer shell 300 and the comb teeth 302. Through mechanical compression, the two outer shells 300 are fastened together. At the same time, the elastic force generated by the deformation of the annular pad 404 and the limiting plate 401 together form a snap-lock, ensuring that the stability is not reduced after assembly, and improving the convenience of operation and product durability.
[0021] like Figure 2-4 As shown, rotating beads 500 are rotatably connected to the outer corner of the upper end of the outer shell 300 and the outer corner of the upper end of the comb teeth 302. The rotating beads 500 are in rolling engagement with the lower end of the inner arc surface of the plug 301.
[0022] The rotating ball 500 on the outer side of the outer shell 300 and the comb teeth 302 rolls along the inner wall of the plug 301, reducing friction during disassembly and assembly.
[0023] The working principle of the hair straightener / curling iron provided by this utility model is as follows: During use, the negative ion generator 200 inside the handle 100 releases negative ions synchronously through the comb bristles 201 and comb teeth 302 to achieve smooth styling of the hair. When it is necessary to clean the comb bristles 201 and comb teeth 302, the user first rotates the threaded plug 301 counterclockwise to release the pressure exerted on the outer casing 300 by the plug 301, the limiting ring 403, and the annular pad 404. At this time, gently pull the outer casing 300 upwards to allow the two... The limiting plate 401 on the inner side of the outer shell disengages from the boss 402 of the limiting seat 400, and then the outer shell 300 is symmetrically pried open outwards. At this time, the limiting posts 303 on both sides of the outer shell 300 will separate from the limiting holes of the symmetrical outer shell 300, exposing the internal comb bristles 201. The user can then pull out the comb teeth 302 that are movably inserted into the slots to rinse or replace the various components. During assembly, first insert the comb teeth 302 one by one into the slots on the outer arc surface of the outer shell 300, and then pass the comb bristles 201 through the outer shell 300. Insert the outer shell 300 into the groove at the upper end of the handle 100, so that the limiting plate 401 slides into the limiting seat 400. Then, fasten the two outer shells 300 together, ensuring that the limiting post 303 is precisely inserted into the limiting hole of the other outer shell 300. Finally, tighten the plug 301 clockwise. The inclined surface of its lower inner wall will press against the inclined edges of the outer shell 300 and the comb teeth 302, and the two outer shells 300 will be fastened together by mechanical compression. At the same time, the elastic force generated by the deformation of the annular pad 404 and the limiting plate 400 will be engaged. 01 together form a snap-lock, and the rotating ball 500 on the outer side of the outer shell 300 and the comb teeth 302 rolls along the inner wall of the plug 301 to reduce the friction of disassembly and assembly. This design achieves a balance between quick disassembly and stable locking by rotating the plug 301 in conjunction with multiple limiting structures, so that the comb teeth 302 and comb bristles 201 can be quickly exposed to the outside for rinsing or replacement, avoiding damage to hair follicles caused by the accumulation of chemical residues. Moreover, the snap-lock limiting structure ensures that the stability is not reduced after assembly, improving the convenience of operation and the durability of the product.

[0025] The above description is the preferred embodiment of this utility model.
