Description

Technical Field

[0001] This utility model relates to the field of hair styling tools, and in particular to a hair straightener with anti-scalding edges. Background Technology

[0002] A hair straightener is a hair styling tool used to straighten curly or irregular hair.

[0003] A significant problem with traditional hair straighteners is that the edges of the heating elements can easily burn the user's fingers or skin. This is because the heating elements are usually exposed and reach extremely high temperatures, especially when frequently adjusting hair position. Users may accidentally come into contact with these hot areas, resulting in accidental burns.

[0004] Chinese patent CN221059819U discloses a hair straightener that uses a heat insulation plate on the side of the heating element away from the working plate. This allows heat diffused onto the straightener's casing to be reflected back onto the working plate, thus reducing the electrical energy required for the heating element and preventing burns to the user's hands from caused by the straightener's casing overheating.

[0005] However, while the heat insulation plate in the aforementioned patent can reduce the conduction of heat to the hair straightener housing, its effective range is limited and it fails to completely eliminate the risk of users coming into contact with the edge of the heating element. In particular, when users operate it improperly or the device is accidentally dropped, they may still come into direct contact with the high-temperature heating element. In addition, the aforementioned patent does not provide an active cooling mechanism to reduce the temperature around the heating element. Even if the heat insulation plate reduces some heat conduction, heat accumulation after prolonged use may still lead to local overheating and increase the risk of burns.

[0006] To address this, a hair straightener with anti-scalding edges was specially designed to overcome the shortcomings of existing technology. Utility Model Content

[0007] In order to overcome the shortcomings of the existing technology, the present invention provides a hair straightener with anti-scalding edge.

[0008] A hair straightener with anti-scalding edges includes a lower plate, heating elements, an upper plate, a return spring, a mounting plate, a stop bar, an insulating sleeve, a heat insulation pad, an electric fan, a fan hood, and a protective net. The lower plate has a cavity at its front. Two heating elements are present; one is mounted at the front top of the lower plate. The upper plate is hinged to the upper part of the lower plate. The upper plate has a built-in power module. The other heating element is mounted at the front bottom of the upper plate. A return spring is located at the hinge point between the lower and upper plates. Both the upper and lower plates extend outwards at their rear, forming a gripping structure. The upper plate has an external... Mounting plates are located on both sides near the bottom. Several equidistant baffles extend from the lower part of the mounting plates. Each baffle is covered with an insulating sleeve. A heat insulation pad is located at the front of the top of the upper clamping plate. An electric fan is installed at the rear of the cavity of the lower clamping plate. The air inlet of the electric fan faces downward. Several equidistant air outlets are opened on both sides of the top of the lower clamping plate near the heating element and on both sides near the top of the side. Each air outlet is covered with a protective net. Air collecting hoods are located on both sides of the upper part of the cavity of the lower clamping plate corresponding to the air outlets. The rear of the two air collecting hoods are connected and extend to the outside of the air outlet of the electric fan. The air collecting hoods communicate with the air outlets.

[0009] Furthermore, the edges of both the upper and lower clamping plates are rounded and smooth.

[0010] Furthermore, it also includes a clip plate and a straightening comb. The bottom of the lower clip plate has a clip plate with a slot inside, in which a straightening comb that is pointing downwards is engaged.

[0011] Furthermore, it also includes a display screen and a temperature control button. The display screen is installed at the top center of the upper clamping plate, and the temperature control button is electrically connected to the display screen on the outer side of the upper clamping plate. An on / off switch is located on the outer side of the upper clamping plate adjacent to the temperature control button. The on / off switch and the heating element are also electrically connected to the display screen.

[0012] Furthermore, it also includes limit blocks, hinge blocks, screws and lock caps. Limit blocks are symmetrically provided on the lower outer side of the upper clamping plate, and hinge blocks are provided on the upper outer side of the lower clamping plate below the limit blocks. Screws are hinged to the two hinge blocks, and lock caps are threaded through the lower part of the screws. The lock caps are in rotatable contact with the limit blocks and abut against each other.

[0013] Furthermore, it also includes anti-slip sleeves, with the extensions of the upper and lower clamps covered with anti-slip sleeves.

[0014] The beneficial effects are: 1. This utility model forms a closed air circulation path by combining an electric fan and a fan shroud, ensuring that cold air can be accurately blown out from the air outlet, effectively reducing the temperature of the heating element edge and protecting the user from burns; the heat insulation pad and insulating sleeve act as a physical barrier, directly blocking heat from being conducted outward, ensuring that the user's skin will not be damaged by high temperature.

[0015] 2. The design of the baffle bar allows hair to pass through smoothly while effectively preventing accidental contact with the heating element by fingers, increasing the safety and comfort of operation; the display screen and temperature adjustment buttons allow users to intuitively understand and control the working status of the hair straightener, improving the convenience and safety of use.

[0016] 3. This utility model ensures the safe storage of the equipment when not in use by using a screw and a locking sleeve, preventing accidental opening and increasing the reliability and safety of the equipment. Attached Figure Description

[0025] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0026] Example: A hair straightener with anti-scalding edges, such as Figures 1-6As shown, the device includes a lower clamping plate 1, heating elements 101, an upper clamping plate 2, a return spring 3, a mounting plate 4, a stop bar 5, an insulating sleeve 6, a heat insulation pad 7, an electric fan 8, an air collector 9, and a protective net 91. The lower clamping plate 1 provides stable mechanical support and provides installation space for other key components, ensuring the stability and functionality of the overall structure of the device. A cavity is opened at the front of the lower clamping plate 1. There are two heating elements 101, which directly contact and heat the hair, changing its shape. One of the heating elements 101 is installed at the top front of the lower clamping plate 1. The upper clamping plate 2 is hinged to the upper part of the lower clamping plate 1. The two components form a closed device. The edges of both the upper clamping plate 2 and the lower clamping plate 1 are smoothly rounded. The upper clamping plate 2 has a built-in power module. Another heating element 101 is installed at the front bottom of the upper clamping plate 2. A return spring 3 is provided at the hinge point between the lower clamping plate 1 and the upper clamping plate 2. Both the upper clamping plate 2 and the lower clamping plate 1 extend outwards at their rear ends, forming a gripping structure. Mounting plates 4 are located on the lower sides of the outer sides of the upper clamping plate 2. Several equidistant baffles 5 extend from the lower part of the mounting plates 4, allowing hair to pass through smoothly while effectively preventing fingers from accidentally touching the high-temperature heating element 101. This significantly improves operational safety and comfort. The baffle 5 is covered with an insulating sleeve 6 to further isolate heat transfer and prevent users from feeling burning sensations upon contact. A heat insulation pad 7 is located at the front of the top of the clamping plate 2, directly blocking heat conduction and ensuring that the user's skin is not damaged by high temperatures upon contact with the clamping plate 2. This provides extra protection, especially during prolonged use. An electric fan 8 is installed at the rear of the cavity of the lower clamping plate 1, with its air inlet facing downwards. Several equidistant air intakes are provided on both sides of the top of the lower clamping plate 1 near the heating element 101, and on the upper sides of the sides. The air outlets and several air vents are equipped with protective nets 91 to prevent foreign objects from entering the hair straightener and to ensure that cold air can be discharged smoothly and maintain good heat dissipation performance. The upper two sides of the cavity of the lower clamp plate 1 are equipped with air collecting hoods 9 corresponding to the positions of the air vents. The rear ends of the two air collecting hoods 9 are connected and extend to the outside of the air supply end of the electric fan 8. The air collecting hoods 9 communicate with several air vents. The electric fan 8 collects air through the air collecting hoods 9. The air collecting hoods 9 guide the cold air to be blown accurately from the air vents, ensuring that the cooling effect is concentrated around the heating element 101, reducing the temperature of the edge of the heating element 101, and further reducing the risk of burns.

[0027] like Figure 1 , Figure 3 and Figure 7 As shown, it also includes a card plate 401 and a straightening comb 10. The bottom of the lower clamp plate 1 is provided with a card plate 401. The card plate 401 has a card slot inside, in which a straightening comb 10 is inserted vertically downward. The straightening comb 10 helps to comb the hair, making it enter the heating area more neatly, improving the straightening effect, and also making it convenient to store and carry.

[0028] like Figure 1As shown, it also includes a display screen 11 and a temperature control button 12. The display screen 11 is installed at the top center of the upper clamping plate 2. The display screen 11 allows users to intuitively understand and control the working status of the device. The temperature control button 12, which is electrically connected to the display screen 11, is provided on the outer side of the upper clamping plate 2. The appropriate temperature level can be selected by adjusting the temperature control button 12 to ensure the best hair styling experience, improving the convenience and safety of use. An on / off switch is provided on the outer side of the upper clamping plate 2 adjacent to the temperature control button 12. The on / off switch and the heating element 101 are also electrically connected to the display screen 11.

[0029] like Figure 1 As shown, it also includes a limit block 14, a hinge block 15, a screw 16, and a locking cap 17. The limit block 14 is symmetrically provided on the lower outer side of the upper clamping plate 2, and the hinge block 15 is provided on the upper outer side of the lower clamping plate 1 below the limit block 14. The screw 16 is hinged to the two hinge blocks 15, and the locking cap 17 is threaded through the lower part of the screw 16. The locking cap 17 is in rotatable contact with the limit block 14 and abuts against it. When not in use, the upper clamping plate 2 and the lower clamping plate 1 can be locked by rotating the locking cap 17 to prevent accidental opening and increase the reliability and safety of the equipment.

[0030] like Figure 1 As shown, it also includes an anti-slip sleeve 13. The extensions of the upper clamp 2 and the lower clamp 1 are covered with the anti-slip sleeve 13, which optimizes the grip experience, reduces the risk of accidental contact with the heating element 101 due to unstable hand grip, and enhances the comfort and safety of use.

[0031] Before use, the user charges the power module via USB cable. After charging, press the power button located on the side of the upper clamp plate 2 to power on the hair straightener. At this time, the display screen 11 lights up and displays the current set temperature and working status. Select the appropriate temperature level according to your hair type and adjust it using the temperature adjustment button 12. The display screen 11 displays the selected temperature in real time to help the user accurately control the heating level. After the user sets the temperature, the upper and lower heating plates 101 start heating to the preset temperature. The electric fan 8 automatically turns on during the heating process. It collects air through the air collector 9 and blows out cool air from the air outlet to form an effective air circulation system, preventing heat from spreading to both sides and protecting the user from burns.

[0032] In operation, press the extensions of the upper clamp 2 and lower clamp 1. The return spring 3 will compress and deform, thereby lifting the upper clamp 2 and separating it from the lower clamp 1, forming an opening for inserting hair. Take a small section of hair and place it between the two heating plates 101, ensuring the hair is evenly distributed within the heating area. Slowly close the upper clamp 2 and lower clamp 1, making the two heating plates 101 in close contact with the hair. Then, smoothly slide the device along the length of the hair, repeating this action from root to tip, until all the hair is straightened. Each time the upper clamp 2 is closed, the return spring 3 provides slight elastic support, ensuring moderate pressure between the clamps—neither too tight to damage the hair nor too loose to affect the effect. The edges of the upper clamp 2 and lower clamp 1 are all smoothly rounded, reducing sharp edges. To prevent potential skin damage, the appropriately spaced baffles 5 allow hair to pass through easily without obstruction, achieving physical isolation and preventing users' fingers from directly contacting the high-temperature heating element 101. The heat insulation pad 7 also prevents users' skin from being damaged by high temperatures after contact with the upper clamping plate 2. Furthermore, the insulating sleeve 6 covering the baffles 5 further isolates heat transfer, preventing users from feeling burning sensations upon touch. After styling, disconnect the USB connection, turn off the power using the on / off switch, and wait a few minutes for the heating element 101 to cool naturally. Then, rotate the screw 16 upwards, gradually bringing it closer to the limiting block 14. At this point, rotate the locking sleeve on the screw 16 until it fully contacts and holds against the limiting block 14, ensuring that the upper clamping plate 2 and lower clamping plate 1 are securely locked, thus guaranteeing the safe storage of this device.

[0033] Additionally, if users wish to achieve a smoother result, they can insert the straightening comb 10 into the slot at the bottom of the lower plate 1 before straightening treatment. The straightening comb 10 helps to comb the hair and make it enter the heating area more neatly. Users hold the extension of the upper plate 2 and the lower plate 1, which is covered with an anti-slip sleeve 13 to increase grip stability.
