Abstract
Description
Technical Field
[0001] This utility model relates to the field of hair styling tools, specifically a portable mini hair straightener. Background Technology
[0002] Hair styling tools refer to various tools and equipment used for hair styling, care, and beautification. There are many types of hair styling tools, including portable mini hair straighteners.
[0003] When using the existing portable mini hair straightener, pressing the unlock button opens the upper and lower plates, and then pressing the power button heats the heating plates fixed inside the upper and lower plates. Hair can then be placed between the heating plates for processing. However, after prolonged use, the surface of the heating plates becomes covered with dandruff and oil. Each time it is cleaned, it can only be cleaned with a cleaning cloth, but the oil on the surface of the heating plates remains and cannot be effectively cleaned. Therefore, there is a need for a mini hair straightener with a detachable heating plate, so that the heating plate can be removed for effective cleaning. Utility Model Content

[0005] This utility model is a portable mini clamp, comprising:
[0006] A clamping plate assembly, comprising an upper clamping plate and a lower clamping plate; one end of the upper clamping plate is movably connected to one end of the lower clamping plate.
[0007] The easy-to-disassemble component includes a heating plate, a connecting strap, a square sleeve, and a limiting rod. The heating plate is snapped into the heating groove at the opposite ends of the upper and lower clamping plates. The connecting straps are arranged in a set and are fixed to both sides of the heating plate. The connecting straps are sleeved with the upper and lower clamping plates. The square sleeve is snapped into the bottom end of the connecting strap. The limiting rod passes through the connection between the connecting strap and the square sleeve, and one end extends to the inner side of the opposite ends of the upper and lower clamping plates.
[0008] Furthermore, the square sleeve has a through hole at the connection with the connecting band, and the connecting band and the square sleeve have limit holes at the points where they pass through the limiting rod.
[0009] Furthermore, the bottom ends of the connecting strip are fixedly connected to two stop bars, one side of which is fitted with the square sleeve.
[0010] Furthermore, the upper clamping plate and the lower clamping plate have limit grooves at their connection with the limit rod, and the limit rod is threadedly connected to the limit groove.
[0011] Furthermore, the clamping plate assembly also includes a battery, a power button, an indicator light, and a heater; the battery is fixed inside one end of the lower clamping plate, the power button and the indicator light are both fixed on one side of the top of the upper clamping plate, and the two are placed alternately, and the heater is fixed in the heating groove at the opposite end of the upper and lower clamping plates.
[0012] Furthermore, it also includes occlusion components;
[0013] The shielding assembly includes a connecting block, a protective shell, and a damping shaft. The connecting block is tightly attached to both sides of the middle section between the upper and lower clamping plates. The protective shell is snapped onto the opposite ends of the upper and lower clamping plates. One end of the inner side of the protective shell is tightly attached to both sides of the connecting block. The damping shaft is movably connected to the connection between the protective shell and the connecting block and clamping plates.
[0014] Furthermore, a magnetic block is fixedly connected to one end of the inner side of the protective shell, and an adsorption block is fixedly connected to one end of the upper and lower clamping plates, with the magnetic block and the adsorption block adsorbing each other.
[0015] This utility model has the following beneficial effects:
[0016] This invention, through the inclusion of a convenient disassembly assembly, allows for easy cleaning of the heating plate. By rotating the limiting rod, it separates from the inner sides of the opposite ends of the upper and lower clamping plates via threads. Simultaneously, the limiting rod separates from the square sleeve and connecting strap. Then, the heating plate is pulled upwards. Due to the elasticity of the connecting strap, the heating plate leaves the heating groove inside the clamping plates and is pushed outwards, causing the connecting strap to separate from the clamping plates. This facilitates the disassembly of the heating plate, enabling thorough cleaning after prolonged use and achieving effective cleaning. Attached Figure Description

Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0027] Please see Figures 1-4 As shown, this utility model is a portable mini clamp, comprising:
[0028] The clamping plate assembly includes an upper clamping plate 11 and a lower clamping plate 12; one end of the upper clamping plate 11 is movably connected to one end of the lower clamping plate 12.
[0029] The clamping plate assembly also includes a battery 13, a power button 14, an indicator light 15, and a heater 16; the battery 13 is fixed inside one end of the lower clamping plate 12, the power button 14 and the indicator light 15 are both fixed on one side of the top of the upper clamping plate 11, and the two are placed alternately, and the heater 16 is fixed in the heating groove at the opposite end of the upper clamping plate 11 and the lower clamping plate 12.
[0030] The upper clamp 11 and lower clamp 12 together form the clamp. The clamp shell is made of lightweight and high-strength aluminum alloy with a frosted surface, which reduces the overall weight, enhances the grip, and prevents slippage. The battery 13 is a 14500 lithium battery, which can provide stable power output to the clamp and ensure battery life. The power button 14 is used to start the clamp, and the indicator light 15 is used to determine the working status. The heater 16 can quickly reach the temperature suitable for styling. It can generally heat up to the working temperature range of 150℃-200℃ within 30 seconds, effectively reducing styling time. The clamp is equipped with a high-precision thermistor and intelligent temperature control chip inside, which monitors the temperature of the heating plate in real time and controls the temperature fluctuation within ±5℃ to avoid damage to the hair due to excessive temperature.
[0031] The easy-to-disassemble component includes a heating plate 21, a connecting strap 22, a square sleeve 23, and a limiting rod 24. The heating plate 21 is snapped into the heating groove at the opposite ends of the upper clamping plate 11 and the lower clamping plate 12. The connecting straps 22 are set in a group and are fixed on both sides of the heating plate 21. The connecting straps 22 are sleeved with the upper clamping plate 11 and the lower clamping plate 12. The square sleeve 23 is snapped into the bottom end of the connecting strap 22. The limiting rod 24 passes through the connection between the connecting strap 22 and the square sleeve 23, and one end extends to the inner side of the opposite ends of the upper clamping plate 11 and the lower clamping plate 12.
[0032] The heating plate 21 is used to process the hairstyle, the connecting strap 22 is used to further stabilize the connection between the heating plate 21 and the clamping plate, the square sleeve 23 is used to protect the opening at the bottom of the connecting strap 22, and the limiting rod 24 is used to stabilize the connection between the connecting strap 22 and the clamping plate and prevent the heating plate 21, the connecting strap 22 and the clamping plate from separating.
[0033] The square sleeve 23 has a through hole 25 at the connection with the connecting band 22, and the connecting band 22 and the square sleeve 23 have limit holes 26 at the connection with the limiting rod 24.
[0034] The bottom ends of the connecting strip 22 are fixedly connected to the two sides of the stop bar 27, and one side of the stop bar 27 is in contact with the square sleeve 23;
[0035] The upper clamping plate 11 and the lower clamping plate 12 are provided with a limit groove 28 at the connection with the limit rod 24, and the limit rod 24 is threadedly connected to the limit groove 28.
[0036] The through hole 25 is used for the connection between the square sleeve 23 and the connecting band 22. The limiting hole 26 is used for the insertion and rotation of the limiting rod 24. The stop rod 27 positions the square sleeve 23. The limiting groove 28 is used for the connection between the bottom end of the limiting rod 24 and the upper clamping plate 11 and the lower clamping plate 12. Insert the limiting rod 24 into the limiting hole 26 and push the limiting rod 24 so that one end of the limiting rod 24 is inserted into the limiting groove 28. Rotate the limiting rod 24 so that the limiting rod 24 is securely connected to the limiting groove 28 through the thread.
[0037] Working principle: When the component is not in use, the heating plate 21 is engaged in the heating groove at the opposite ends of the upper clamping plate 11 and the lower clamping plate 12. The connecting strap 22 is sleeved with the clamping plate, and the limiting rod 24 is securely connected to the limiting groove 28. When the component is in use, the limiting rod 24 is rotated by hand, so that the limiting rod 24 is separated from the inner side of the limiting groove 28 through the thread. Then, the limiting rod 24 is pulled outward, and the limiting rod 24 is separated from the limiting hole 26 on the surface of the square sleeve 23 and the connecting strap 22. Then, the heating plate 21 is pulled upward by hand. Due to the elasticity of the connecting strap 22, the heating plate 21 leaves the heating groove inside the upper clamping plate 11 and the lower clamping plate 12 and is pushed outward, so that the heating plate 21 drives the connecting strap 22 to separate from the clamping plate, thereby realizing the disassembly of the heating plate 21, which facilitates the effective cleaning of the disassembled heating plate 21.
[0038] Please see Figure 1 , Figure 5 As shown, this embodiment, based on the above embodiment, further includes:
[0039] Obscuring components;
[0040] The shielding assembly includes a connecting block 31, a protective shell 32, and a damping shaft 33. The connecting block 31 is tightly attached to both sides of the middle section between the upper clamping plate 11 and the lower clamping plate 12. The protective shell 32 is snapped onto the opposite ends of the upper clamping plate 11 and the lower clamping plate 12. The inner side of the protective shell 32 is tightly attached to both sides of the connecting block 31. The damping shaft 33 is movably connected to the connection between the protective shell 32 and the connecting block 31 and the clamping plate.
[0041] The connecting block 31 is used to connect the protective shell 32 and the clamping plate. The protective shell 32 shields the inner limiting rod 24 and the connecting belt 22. The damping shaft 33 is used for the rotation of the connecting block 31 and the protective shell 32.
[0042] A magnetic block 35 is fixedly connected to one end of the inner side of the protective shell 32, and an adsorption block 34 is fixedly connected to one end of the upper clamping plate 11 and the lower clamping plate 12. The magnetic block 35 and the adsorption block 34 are attracted to each other.
[0043] The magnetic block 35 and the adsorption block 34 are used together to connect the protective shell 32 and the clamping plate. When the protective shell 32 is in the closed state, the magnetic block 35 is attracted to the adsorption block 34 by magnetic force, thereby stabilizing the connection between the protective shell 32 and the clamping plate. In addition, the inner limiting rod 24 and the connecting strip 22 can be covered by the protective shell 32, improving the aesthetics of the clamping plate.
[0044] Working principle: When the component is not in use, the limiting rod 24 is securely connected to the limiting groove 28, and the protective shell 32 is in a closed state. When the heating plate 21 is disassembled, the protective shell 32 is pushed by hand. The thrust is pushed through the protective shell 32 to push the damping shaft 33, causing the protective shell 32 to rotate outward through the damping shaft 33. This causes the magnetic block 35 to separate from the adsorption block 34, so that the protective shell 32 opens and exposes the inner limiting rod 24, making it convenient for the user to rotate the limiting rod 24.
