Heat conducting plate for straight hair and hair styling device

Abstract

The present invention is applicable to the field of heat conduction technology for hair styling. Disclosed are a heat conduction plate for straightening hair and a hair styling device. The heat conduction plate comprises a heat conduction body, comprising a styling surface that contacts the hair during styling and a heat receiving surface that conducts heat to a heat-generating component. The styling surface comprises a first flat surface and a second flat surface, with a first curved surface and a second curved surface smoothly connected to the first curved surface disposed between the first and second flat surfaces. The first curved surface protrudes outward from the first flat surface, while the second curved surface is recessed into the second flat surface. When the two heat conduction bodies are rotated 180 degrees relative to each other and come into contact with each other, a separation gap is formed between the upper and lower curved surfaces. During use, the hair styling device has two heat conduction bodies. Since each heat conduction plate surface does not form a large flat contact, the hair styling device can avoid generating a large clamping force when styling a small amount of hair, which can cause discomfort when the head has a small area of ​​contact, thereby improving the user experience.

Description

Technical Field

[0001] The present invention relates to the technical field of heat conduction plates, and in particular to a heat conduction plate for hair straightening and a hair styling device. Background Art

[0002] Existing hair styling devices, such as hair straighteners, typically utilize two closable clamping plates, each with two heat-conducting aluminum plates and an electric heating element to heat the aluminum plates. During use, hair is placed between the two heat-conducting aluminum plates, clamped, and moved to straighten the hair. Styling is typically performed on a portion of the hair first, followed by the adjacent portion. This prevents damage to the already straightened hair from heat dissipating before the hair is straightened again. Because a wide range of hair can be clamped initially, the clamping and moving process does not cause discomfort or traction on the scalp. However, when styling hair on smaller portions of hair on either side, the scalp can be pulled and painful, and this portion of hair must be straightened, otherwise achieving a consistent, desired hairstyle is difficult. Summary of the Invention

[0003] The main technical problem solved by the present invention is to provide a heat conduction plate for straight hair and a hair styling device, wherein the heat conduction plate for straight hair can produce a greater pulling effect on the scalp during straight hair styling, thereby improving the user experience.

[0004] To solve the above-mentioned technical problems, the present invention provides a heat-conducting plate for hair straightening, comprising a heat-conducting body, the heat-conducting body including a styling surface for contacting hair during styling and a heat-receiving surface for conducting heat with a heat-generating component. The styling surface is provided with a first flat surface and a second flat surface, with a first curved surface and a second curved surface smoothly connected to the first curved surface provided between the first and second flat surfaces. The first curved surface protrudes outward from the first plane, and the second curved surface is recessed into the second plane. When the two heat-conducting bodies are rotated 180 degrees to form a clamped state, a non-contact surface is formed between the first and second curved surfaces, and a separation gap is formed between the upper and lower curved surfaces.

[0005] Furthermore, the first arc surface and the second arc surface are not centrosymmetrical.

A pressing groove is provided on the other side of the protrusion along the length direction of the heat conducting body, and the pressing groove is provided with a slope on the side close to the heat receiving surface that can press the protrusion.

[0011] Furthermore, when the protrusion is engaged, the engagement surface thereof and the fixing surface on the fixing member are preferably at 90 degrees, and the protrusion is provided with an inclined surface at the end.

[0012] Furthermore, the separation gap has an S-shaped structure.

[0013] The present invention also provides a hair styling device, comprising two axially connected upper and lower clamping plates, each clamping plate being provided with an electric heating component and a heat conducting plate in contact with the electric heating component. The heat conducting plate comprises a heat conducting body, which includes a styling surface for contacting hair during styling and a heat receiving surface for conducting heat with the heat generating component. The styling surface comprises a first flat surface and a second flat surface, with a first curved surface and a second curved surface smoothly connected to the first curved surface being provided between the first and second flat surfaces. The first curved surface protrudes outward from the first flat surface, and the second curved surface is recessed into the second flat surface. When the two heat conducting bodies are rotated 180 degrees relative to each other so that the two flat surfaces and the forming surface are in contact, a separation gap is formed between the upper and lower curved surfaces.

[0014] Furthermore, the first arc surface and the second arc surface are not centrosymmetrical.

[0015] Furthermore, the height of the second arc surface from the second plane is greater than the height of the first arc surface from the first plane.

[0016] Furthermore, the first arc surface and the second arc surface are on the same plane.

[0017] Furthermore, the first plane and the second plane have the same width.

[0018] Furthermore, both sides of the heat-conducting body are provided with blocking portions extending and protruding in a direction perpendicular to the heat contact surface.

[0019] Furthermore, the heat contact surface is provided with two symmetrically arranged mounting portions for mounting and fixing, and a cavity or groove for accommodating the electric heating component is formed between the two mounting portions.

[0020] Furthermore, the mounting portion is provided with a snap-fit ​​structure away from the heat contact surface, a protrusion is provided on the outside of the snap-fit ​​structure, and the protrusion is provided with a slope at the end.

The first curved surface protrudes outward from the first flat surface, while the second curved surface is recessed into the second flat surface. When the two heat-conducting bodies are rotated 180 degrees relative to each other and come into contact with each other, a separation gap is formed between the upper and lower curved surfaces. During use, the hair styling device has two heat-conducting bodies. Since each heat-conducting plate surface does not form a large flat contact surface, the hair styling device can avoid generating a large clamping force when styling a small amount of hair, which can cause discomfort when the head is subjected to a small amount of force, thereby improving the user experience.

[0035] like Figure 1-Figure 3 As shown, the present invention provides an embodiment of a heat conducting plate for hair straightening.

[0036] The heat-conducting plate for hair straightening includes a heat-conducting body 1, which includes a styling surface 10 for contacting hair during styling and a heat-receiving surface 13 for conducting heat transfer with a heat-generating component. The styling surface 10 has a first flat surface 101 and a second flat surface 102. A first curved surface 103 and a second curved surface 104 smoothly connected to the first curved surface 103 are located between the first flat surface 101 and the second flat surface 102. The first curved surface 103 protrudes outward from the first flat surface 101, while the second curved surface 104 is recessed into the second flat surface 102. When the two heat-conducting bodies are rotated 180 degrees relative to each other and the two flat surfaces and the styling surface come into contact, a separation gap A is formed between the two curved surfaces.

[0037] Specifically, the heat receiving surface 13 is provided with two mounting parts 12 for installation and fixation, and the two mounting parts 12 are symmetrically arranged. A cavity or groove for accommodating electric heating components is formed between the mounting parts 12. The mounting part 12 is provided with a snap-fit ​​structure away from the heat receiving surface 13, and a protrusion 122 is provided on the outside of the snap-fit ​​structure. When the protrusion 122 is engaged, the snap-fit ​​surface and the fixing surface on the fixing part are preferably 90 degrees, and the protrusion 122 is provided with an inclined surface at the end. A pressing groove 121 is provided on the other side of the protrusion 122, and the pressing groove 121 is arranged along the length direction of the heat-conducting body 1. The pressing groove 121 is provided with an inclined surface on the side close to the heat receiving surface 13, which can press the protrusion 122 against the fixing part.

[0038] The first curved surface 103 and the second curved surface 104 are non-centrally symmetrical, that is, the curvatures of the two curved surfaces are different, wherein the height of the second curved surface 104 from the first plane 101 or the second plane 102 is greater than the height of the first curved surface 103 from the first plane 101 or the second plane 102.

[0039] During use, when the two heat-conducting bodies 1 are rotated 180 degrees to form a clamped state, a non-contact surface is formed between the two first curved surfaces 103 and the second curved surface 104, and a separation gap A is formed between the lower and upper curved surfaces. The S-shaped structure of this separation gap ensures that even a small amount of hair passing through the S-shaped separation gap can contact the two curved surfaces to generate heating, while also avoiding the large clamping force that would normally occur. The first plane 101 and the second plane 102 are in contact, that is, an S-shaped separation gap is formed between the first plane 101 and the second plane 102. The first curved surface 103 and the second curved surface 104 are on the same plane. The widths of the first plane 101 and the second plane 102 can be the same.

[0040] Since the surface of each heat conducting plate does not form a large plane contact, it will not generate a large clamping force when styling less hair, which will cause discomfort when the head has a smaller force area, thereby improving the user experience.

[0041] As needed, both sides of the heat-conducting body 1 are provided with blocking portions 11 extending and protruding in a direction perpendicular to the heat receiving surface.

[0042] As needed, such as Figure 4 As shown, the two heat-conducting bodies 1 can also be arranged axially symmetrically, that is, the upper and lower heat-conducting bodies 1 are reversed 180 degrees and arranged in pairs. In this way, a local contact surface is formed on the first curved surface 103, and a first gap A and a second gap B are respectively formed between the two planes of the upper and lower heat-conducting bodies 1. This can further reduce the contact area of ​​straight hair and avoid generating a large clamping force when styling a small amount of hair, which would cause discomfort when the head is subjected to a smaller force area, thereby improving the user experience.

[0043] As needed, the first curved surface 103 and the second curved surface 104 are separated by the intersection surface of the first plane or the second plane, and the projection widths of the first curved surface 103 and the second curved surface 104 perpendicular to the first plane or the second plane are the same.

[0044] like Figure 1-3As shown, the present invention also provides a hair styling device comprising two axially connected upper and lower clamping plates, each of which is provided with an electric heating component and a heat conducting plate in contact with the electric heating component. The heat conducting plate comprises a heat conducting body 1, which includes a styling surface 10 for contacting hair during styling and a heat receiving surface 13 for heat transfer to the heat generating component. The styling surface 10 comprises a first flat surface 101 and a second flat surface 102. A first curved surface 103 and a second curved surface 104 smoothly connected to the first curved surface 103 are provided between the first flat surface 101 and the second flat surface 102. The first curved surface 103 protrudes outward from the first flat surface 101, while the second curved surface 104 is recessed into the second flat surface 102. When the two heat conducting bodies are rotated 180 degrees relative to each other and the two flat surfaces and the forming surface come into contact, a separation gap is formed between the two curved surfaces.

[0045] Specifically, the heat receiving surface 13 is provided with two mounting parts 12 for installation and fixation, and the two mounting parts 12 are symmetrically arranged. A cavity or groove for accommodating electric heating components is formed between the mounting parts 12. The mounting part 12 is provided with a snap-fit ​​structure away from the heat receiving surface 13, and a protrusion 122 is provided on the outside of the snap-fit ​​structure. When the protrusion 122 is engaged, the snap-fit ​​surface and the fixing surface on the fixing part are preferably 90 degrees, and the protrusion 122 is provided with an inclined surface at the end. A pressing groove 121 is provided on the other side of the protrusion 122, and the pressing groove 121 is arranged along the length direction of the heat-conducting body 1. The pressing groove 121 is provided with an inclined surface on the side close to the heat receiving surface 13, which can press the protrusion 122 against the fixing part.

[0046] The first curved surface 103 and the second curved surface 104 are non-centrally symmetrical, that is, the curvatures of the two curved surfaces are different, wherein the height of the second curved surface 104 from the first plane 101 or the second plane 102 is greater than the height of the first curved surface 103 from the first plane 101 or the second plane 102.

[0047] During use, when the two heat-conducting bodies 1 are rotated 180 degrees to form a clamped state, a non-contact surface is formed between the first and second curved surfaces 103 and 104, and a separation gap A is formed between the lower and upper curved surfaces. This separation gap can be configured as an S-shaped structure to ensure that even when a small amount of hair passes through the S-shaped separation gap, it can still contact the two curved surfaces to generate heating, while also avoiding the large clamping force that would normally occur. The first and second flat surfaces 101 and 102 are in contact, forming an S-shaped separation gap between the first and second flat surfaces 101 and 102. The first and second curved surfaces 103 and 104 are coplanar. The widths of the first and second flat surfaces 101 and 102 can be the same. Because the heat-conducting plate surfaces of the heat-conducting bodies 1 do not form a large planar contact and a larger separation gap A is formed in the center, a greater clamping force can be generated when styling a small amount of hair, eliminating the discomfort that occurs when the head is subjected to less force, thereby improving the user experience.

[0048] As needed, both sides of the heat-conducting body 1 are provided with blocking portions 11 extending and protruding in a direction perpendicular to the heat receiving surface.

[0049] As needed, such as Figure 4 As shown, the two heat-conducting bodies 1 can also be arranged axially symmetrically, that is, the upper and lower heat-conducting bodies 1 are reversed 180 degrees and arranged in pairs. In this way, a local contact surface is formed on the first curved surface 103, and a first gap A and a second gap B are respectively formed between the two planes of the upper and lower heat-conducting bodies 1. This can further reduce the contact area of ​​straight hair and avoid generating a large clamping force when styling a small amount of hair, which would cause discomfort when the head is subjected to a smaller force area, thereby improving the user experience.

[0050] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein, and these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
