[0001] This utility model relates to the technical field of hair perming devices, specifically a hair perming device. Background Technology

[0002] In today's society, beauty has become a pursuit for many people. Beautiful hair can better showcase one's individual beauty, and hair styling tools are indispensable. Hair styling tools generally include two types: straighteners and curling irons. A curling iron is a handheld electronic product used to curl hair. Its main components are a handle and a heating cylinder. The design of the curling iron uses a circuit panel to control the temperature. The heating cylinder is made of tourmaline ceramic, which can evenly distribute heat, circulate heat, improve the hair protein structure to create curls, and protect the hair quality during the curling process.

[0003] Chinese Patent Publication No. CN217137084U discloses a three-tube hair curler that does not require punching. Its key technical features include a first curling tube and a second and third curling tube symmetrically arranged on the surface of a wave plate with the first curling tube as its central axis. The end of the second curling tube is connected to one end of a left connector via a second screw, and the end of the third curling tube is connected to one end of a right connector via a third screw. The first curling tube is installed on the upper surface of the middle part of the wave plate, and its end is connected to one end of a middle connector via a fourth screw. The other end of the middle connector is fixedly connected to the front end of a handle. The upper surfaces of the left and right connectors are connected by a clip head. A spring for unfolding the second and third curling tubes is installed at the bottom of the clip head, and the bottom of the spring is engaged with a groove provided on the middle connector head.

[0004] In the above solution, the first, second, third, fourth, and fifth screws are used to install the first, second, and third heating tubes and the wave plate, which results in the following disadvantage: the hair-curling components of the hair curler require additional tools to be installed by screws, making disassembly and assembly inconvenient. Utility Model Content

[0005] The purpose of this invention is to provide a hair curler to solve the problem that the hair curling parts of the hair curler require additional tools for installation by screws, making disassembly and assembly inconvenient.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a hair perm, including an upper shell, the upper shell being rotatably disposed on the top surface of a lower shell, hair perming components being detachably installed inside both the upper and lower shells, movable holes being provided on the left and right sides of both the upper and lower shells, buttons being movably disposed in each of the two movable holes, mounting grooves being provided on the inner sides of both buttons, two baffles being fixed inside both the upper and lower shells, springs being fixed inside the two mounting grooves, the inner ends of the two springs being fixedly connected to the outer sides of the two baffles, a first L-shaped locking block being fixed to the front side of each of the two buttons, and two second L-shaped locking blocks being fixed to the rear side of each of the two hair perming components, the two second L-shaped locking blocks engaging with the two first L-shaped locking blocks respectively, and both the first L-shaped locking blocks and the second L-shaped locking blocks having inclined surfaces.

[0007] Preferably, the top and bottom surfaces of the two buttons each have two protruding strips fixed on them.

[0008] Preferably, the inner walls of the upper and lower shells are provided with sliding grooves on the left and right sides, and the two hair-curling parts are fixed with sliding strips on the left and right sides, respectively, and the two sliding strips are slidably disposed in the two sliding grooves.

[0009] Preferably, a positioning block is fixed to the outer rear side of each of the two hair-curling components, and a positioning groove is provided on the front side of both the upper and lower housings, with the two positioning grooves respectively positioning the two positioning blocks.

[0010] Preferably, both the outer walls of the upper and lower shells are fixed with heat insulation pads, and both heat insulation pads are provided with anti-slip textures.

[0011] Preferably, the outer walls of the upper and lower shells are provided with a number of heat dissipation holes on the left and right sides.

[0012] Compared with existing technologies, a hair curler that adopts the above-mentioned technical solution has the following beneficial effects: First, during use, the hair-curling parts are quickly disassembled and assembled through the coordinated action of the upper shell, lower shell, hair-curling parts, movable holes, buttons, mounting slots, baffles, springs, first L-shaped locking blocks and second L-shaped locking blocks. The operation is simple and convenient, without the need for additional tools, which improves the convenience and efficiency of use. Second, during use, the raised strip will tightly abut against the inner wall of the upper or lower housing, playing a crucial limiting role. This effectively prevents the button from protruding too far from the moving hole, thus preventing it from affecting the overall appearance and user experience. The cooperation between the slider and the groove can limit the movement of the perm piece, guiding it to move in the correct direction and preventing offset or wobbling during installation, thereby improving the accuracy of perm piece installation. The positioning block will accurately insert into the positioning groove, playing an auxiliary positioning role and further ensuring the accurate position of the perm piece within the housing. Thirdly, during use, the anti-slip texture on the heat-insulating pad increases the friction between the hand and the pad, allowing the user to grip the hair curler more firmly and preventing it from slipping, further improving convenience and safety. The ventilation holes promote airflow, allowing heat to dissipate quickly into the surrounding environment, effectively reducing the internal temperature of the hair curler and ensuring it operates at a suitable temperature, thus improving its stability and durability.

[0018] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0019] like Figures 1-4As shown, a hair curler includes an upper housing 1, which is rotatably mounted on the top surface of a lower housing 2. Hair curling components 3 are detachably installed inside both the upper housing 1 and the lower housing 2. Movable holes 4 are provided on the left and right sides of both the upper housing 1 and the lower housing 2. Buttons 5 are movably installed in each of the two movable holes 4. Mounting grooves 6 are provided on the inner side of each of the two buttons 5. Two baffles 7 are fixed inside both the upper housing 1 and the lower housing 2. Springs 8 are fixed inside the two mounting grooves 6. The inner ends of the two springs 8 are fixedly connected to the outer sides of the two baffles 7, respectively. A first L-shaped locking block 9 is fixed to the front side of each of the two buttons 5. Two second L-shaped locking blocks 10 are fixed to the rear side of each of the two hair curling components 3. The two second L-shaped locking blocks 10 are engaged with the two first L-shaped locking blocks 9, respectively. Both the first L-shaped locking blocks 9 and the second L-shaped locking blocks 10 have inclined surfaces.

[0020] In use, when the user needs to disassemble the hair perming component 3, the operation is extremely simple. Just gently press the two buttons 5 on the upper housing 1 or the lower housing 2. As the buttons 5 move inwards, the connected first L-shaped latches 9 move closer together, compressing the spring 8. Continue pressing the buttons 5 until the two first L-shaped latches 9 completely disengage from the two second L-shaped latches 10. Once completely separated, the hair perming component 3 is unlocked, and the user can easily move the entire hair perming component 3 forward to remove it from the upper housing 1 or the lower housing 2. Conversely, when the user needs to install the hair perming component 3... The hair-curling component 3 is pushed backward into the upper housing 1 or the lower housing 2. As the pushing action continues, the inclined surfaces of the two second L-shaped locking blocks 10 will press against the inclined surfaces of the two first L-shaped locking blocks 9 respectively, causing the two first L-shaped locking blocks 9 to move closer to each other. The spring 8 is compressed again. When the inclined surface of the second L-shaped locking block 10 passes over the inclined surface of the first L-shaped locking block 9, the squeezing force on the button 5 disappears. The spring 8 pushes the button 5 and the first L-shaped locking block 9 outward with its own elasticity, realizing automatic reset, thereby making the first L-shaped locking block 9 and the second L-shaped locking block 10 accurately engage, completing the installation and fixing of the hair-curling component 3.

[0021] Through the coordinated action of the upper shell 1, lower shell 2, hair curling component 3, movable hole 4, button 5, mounting slot 6, baffle 7, spring 8, first L-shaped locking block 9 and second L-shaped locking block 10, the hair curling component 3 can be quickly disassembled and assembled. The operation is simple and convenient, without the need for additional tools, which improves the convenience and efficiency of use.

[0022] like Figure 2 and Figure 3 As shown, the top and bottom surfaces of the two buttons 5 each have two protrusions 11 fixed on them.

[0023] During use, when button 5 is located inside the upper housing 1 or lower housing 2, the protrusion 11 will be tightly pressed against the inner wall of the upper housing 1 or lower housing 2, playing a key limiting role. This can effectively prevent button 5 from extending too far out of the movable hole 4, preventing the overall appearance and operation experience from being affected by the excessive extension of button 5. At the same time, it can also prevent button 5 from falling out of the movable hole 4, ensuring that button 5 is always in the correct position, ensuring the normal use of the hair curling part 3's disassembly and assembly function, and improving stability and reliability.

[0024] like Figures 1-4 As shown, the upper shell 1 and the lower shell 2 have sliding grooves 12 on the left and right sides of their inner walls. The two hair perming parts 3 have sliding strips 13 fixed on the left and right sides. The two sliding strips 13 are slidably arranged in the two sliding grooves 12. The two hair perming parts 3 have positioning blocks 14 fixed on their outer rear sides. The upper shell 1 and the lower shell 2 have positioning grooves 15 on their front sides. The two positioning grooves 15 respectively position the two positioning blocks 14.

[0025] During use, when the user installs the perm part 3 into the upper housing 1 or lower housing 2, first align the sliding strips 13 fixed on both sides of the perm part 3 with the sliding grooves 12 opened on the left and right sides of the inner walls of the upper housing 1 and lower housing 2, and then smoothly slide it in. The cooperation between the sliding strips 13 and the sliding grooves 12 can limit the perm part 3, guide the perm part 3 to move in the correct direction, and avoid deviation or shaking during the installation process, thereby improving the accuracy of the perm part 3 installation, making the installation process smoother, reducing repeated adjustments caused by inaccurate installation, and improving the user experience. After the user slides the perm part 3 into the interior of the upper housing 1 or lower housing 2, the positioning block 14 will accurately insert into the positioning groove 15, which plays an auxiliary positioning role, further ensuring that the position of the perm part 3 in the housing is accurate, preventing the perm part 3 from loosening or shifting after installation, ensuring the connection stability between the perm part 3 and the upper housing 1 and lower housing 2, and making the perm 3 work more stably and reliably during use.

[0026] like Figures 1-4 As shown, heat insulation pads 16 are fixed on the outer walls of both the upper shell 1 and the lower shell 2. Anti-slip textures 17 are provided on both heat insulation pads 16. Several heat dissipation holes 18 are provided on the left and right sides of the outer walls of both the upper shell 1 and the lower shell 2.

[0027] During use, when the user needs to pinch the front ends of the upper shell 1 and lower shell 2 to perform the curling operation, the heat insulation pad 16 effectively blocks the heat generated by the curling iron during operation, preventing burns to the user's hands and ensuring user safety. Simultaneously, the anti-slip texture 17 on the heat insulation pad 16 increases the friction between the hand and the pad, allowing the user to grip the curling iron more firmly and preventing slippage, further improving convenience and safety. The heat dissipation holes 18 provide excellent heat dissipation. The curling iron generates heat during operation; if this heat cannot be dissipated in time, the internal temperature may become too high, affecting its performance and lifespan. The heat dissipation holes 18 promote air circulation, allowing heat to dissipate quickly into the surrounding environment, effectively reducing the internal temperature of the curling iron and ensuring it operates at a suitable temperature, thus improving its stability and durability.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
