Description

Technical Field

[0001] This utility model relates to the field of hair styling tools, and in particular to a hair straightener that can protect hair. Background Technology

[0002] Hair straighteners are widely used in the hair styling industry. They heat and straighten hair by transferring heat from an electric current to a heating element that is then transferred to a metal or ceramic heating plate. Because the heating plates of existing hair straighteners are typically made of rigid materials such as metal, ceramic, or a combination of both, they form a rigid structure. During the straightening process, the hair is passed between two heating plates, and the heat from the plates is directly transferred to the hair. Simultaneously, the hair is clamped and pulled, creating tension to achieve straightness. The surface temperature of the heating plates in existing hair straighteners is generally above 180 degrees Celsius, and the metal or ceramic materials are relatively hard and conduct heat quickly. During straightening, the heating plates are in direct contact with the hair, subjecting the hair to a sudden high-temperature impact that can cause thermal damage. Furthermore, the overly hard surface of the heating plates causes frictional damage to the hair cuticles during straightening. Additionally, the high coefficient of friction of the heating plate surface makes it prone to breaking hair. To address this, some have invented components that incorporate lower friction systems on the heating plate to reduce frictional and thermal damage to the hair, such as the anti-slip, energy-saving hair straightener disclosed in patent CN2016200869774. However, this device directly covers the heating plate with a single piece of Teflon fiberglass cloth. This not only significantly increases costs but also lowers the coefficient of friction too much, making it difficult to hold the hair and requiring significantly more strokes and time to straighten it, thus causing inconvenience. Furthermore, because Teflon fiberglass cloth is difficult to adhere, it is not only difficult to fix to the heating plate, but the method of covering the entire heating plate also carries the risk of the Teflon fiberglass cloth easily detaching. Utility Model Content

[0003] This invention addresses the shortcomings of existing technologies by providing a super-smooth hair straightener with a simple structure, a more reasonable design, better balance of tension and reduction of friction coefficient, and a slip-enhancing component that is less likely to fall off.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an ultra-smooth hair straightener, comprising upper and lower handles hinged together to open and close, and heating plate assemblies respectively disposed in the two handles. The heating plate assemblies include upper and lower heating plates and heating elements respectively disposed in the two heating plates. The feature is that: each of the upper and lower heating plates is provided with a mounting groove, and a slip-enhancing component with a friction coefficient, surface hardness and thermal conductivity lower than that of the surface material of the heating plate is installed in the mounting groove. The surface of the slip-enhancing component protrudes from the surface of the heating plate.

[0005] Furthermore, an elastic element is provided in the mounting groove, and the lubrication component is mounted on the elastic element to form an elastic structure.

[0006] Preferably, the lubrication component is made of nylon or Teflon material, and its cross-section is T-shaped, L-shaped or U-shaped. The lubrication component is fixed in the mounting groove of the heating plate by embedding.

[0007] Preferably, the elastic element is a silicone pad, a spring assembly, or a spring sheet. The elastic assembly includes a fixed plate and a spring disposed on the fixed plate for supporting the slip-enhancing component.

[0008] Preferably, the opposing surfaces of the upper and lower heating plates are either planar structures or mutually cooperating arc-shaped structures.

[0009] Preferably, each of the upper and lower heating plates has a mounting groove near its two side edges for installing a lubrication component, with the lubrication components in the upper and lower heating plates facing each other.

[0010] Alternatively, a mounting groove can be provided in the middle of the upper and lower heating plates for installing a lubrication component, with the lubrication components in the upper and lower heating plates facing each other.

[0011] Alternatively, a mounting groove for installing a slip-enhancing component can be provided near one edge of the upper heating plate, and a mounting groove for installing a slip-enhancing component can also be provided near the other edge of the lower heating plate, with the slip-enhancing components in the upper and lower heating plates being staggered.

[0012] Alternatively, a mounting groove is provided on each side edge of the upper heating plate for installing a lubrication component, and a mounting groove is provided in the middle of the lower heating plate for installing a lubrication component, with the lubrication components in the upper and lower heating plates being staggered.

[0013] Alternatively, the upper heating plate has three mounting slots for installing the lubrication enhancement components, and the lower heating plate has two mounting slots for installing the lubrication enhancement components. The lubrication enhancement components in the upper and lower heating plates are staggered.

[0014] This invention utilizes a grooved mounting element installed within the heating plate. The element is easily and securely embedded in the groove, ensuring a stable structure and preventing it from easily falling off. Furthermore, the need for a smaller mounting element reduces costs. The integration of the mounting element with the heating plate body better balances the need to reduce friction and maintain appropriate tension, effectively straightening hair while protecting it from heat damage and breakage, thus reducing the frequency of styling.

[0025] In this embodiment, refer to Figures 1-9 The super-smooth hair straightener includes two handles 1, one upper and one lower, hinged together to open and close. Heating plate assemblies are respectively installed in the two handles 1. Each heating plate assembly includes upper and lower heating plates 6 and 2, and heating elements 8 respectively disposed in the two heating plates. Mounting grooves 7 are provided in both the upper and lower heating plates 6 and 2. Slip-enhancing components 3, whose coefficient of friction, surface hardness, and thermal conductivity are lower than those of the heating plate surface material, are installed in the mounting grooves 7. The surface of the slip-enhancing component 3 protrudes from the surface of the heating plate, so that when hair slides over the heating components, it mainly contacts the slip-enhancing component 3, achieving a balance between reducing friction and maintaining appropriate tension.

[0026] An elastic element 4 is provided in the mounting slot 7, and the lubrication component 3 is installed on the elastic element 4 to form an elastic structure. This allows the lubrication component 3 to deform slightly longitudinally and bend under force to wrap around the hair, relieving the excessive pressure on the hair strands and making the hair strands more evenly stressed and heated. At the same time, due to the wrapping mechanical design, the hair strands can be wrapped and controlled with just a light clamp, reducing the need for repeated styling.

[0027] The lubrication enhancement component 3 is made of nylon or Teflon material, and its cross-section is T-shaped (of course, L-shaped or U-shaped structures are also acceptable). The lubrication enhancement component 3 is fixed in the mounting groove 7 of the heating plate by embedding. It is not only easy to install, but also has a stable structure and is not easy to fall off.

[0028] The elastic element 4 is a silicone pad, a spring assembly, or a spring sheet. The elastic assembly includes a fixing plate 5 and a spring 51 disposed on the fixing plate 5 to support the slip-enhancing component 3. Figure 9 As shown.

[0030] Each of the upper and lower heating plates 6 and 2 has a mounting groove 7 near its side edge for mounting the slip-enhancing component 3. The slip-enhancing components 3 in the upper and lower heating plates 6 and 2 are positioned vertically opposite each other. Figure 3 The first embodiment shown.

[0031] Alternatively, a mounting groove 7 can be provided in the middle of the upper and lower heating plates 6 and 2 for installing the slip-enhancing component 3, with the slip-enhancing components 3 in the upper and lower heating plates 6 and 2 facing each other vertically, such as... Figure 4 The second embodiment is shown.

[0032] Alternatively, a mounting groove 7 can be provided near one edge of the upper heating plate 6 for mounting the slip-enhancing component 3, and a mounting groove 7 can also be provided near the other edge of the lower heating plate 2 for mounting the slip-enhancing component 3. The slip-enhancing components 3 in the upper and lower heating plates 6 and 2 are staggered. Figure 5 The third embodiment shown.

[0033] Alternatively, a mounting groove 7 can be provided near the two side edges of the upper heating plate 6 for installing the slip-enhancing component 3, and a mounting groove 7 can be provided in the middle of the lower heating plate 2 for installing the slip-enhancing component 3. The slip-enhancing components 3 in the upper and lower heating plates 6 and 2 are staggered. Figure 6 The fourth embodiment shown.

[0034] Alternatively, three mounting slots 7 are provided in the upper heating plate 6 for installing the slip-enhancing component 3, and two mounting slots 7 are provided in the lower heating plate 2 for installing the slip-enhancing component 3. The slip-enhancing components 3 in the upper and lower heating plates 6 and 2 are staggered. Figure 7 The fifth embodiment shown.

[0035] Of course, there are other ways to install the lubrication component 3. In short, at least one lubrication component 3 shall be provided in each of the upper and lower heating plates 6 and 2.

[0036] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
