Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hair styling devices, in particular to a hair styling device and a floating device thereof. BACKGROUND

[0002] In the prior art, such as Chinese patent application for invention with publication number CN114732201A, a straightening iron with elastically bendable and deformable heating plate is disclosed, which comprises a shell, a power line assembly, a heating plate assembly, a control switch and a circuit board. The heating plate assembly comprises a heating plate and a heating device. The heating device is horizontally arranged on a plurality of support blocks, and the support blocks are installed on a fixed frame through the support feet at both ends. An elastic rubber seat is installed in the fixed frame, and the support blocks are arranged above the elastic rubber seat. A plurality of U-shaped supports are arranged on the heating device, and the heating plate is horizontally arranged on the U-shaped supports. The prior art designs a support structure mainly composed of U-shaped supports, support blocks and an elastic rubber seat. The heating plate and the heating device are installed and fixed through the support structure. When pulling the hair, the heating plate can produce local elastic bending and deformation along the pulling direction, so that the hair is not clamped and pulled due to excessive clamping pressure, and the hair pulling effect and experience are improved. Although the prior art achieves better flexible straightening effect by setting multiple elastic supports, it still has the following disadvantages: the assembly of the heating plate assembly needs to rely on the assembly of the plastic sleeve 18 and the base 17, the assembly structure is complex, and there are too many parts, which is not conducive to simplifying the assembly structure. Moreover, whether the elastic rubber seat adopts a support column or a spring, it needs to be accurately positioned during assembly, so the assembly requirements are high, the assembly efficiency is low, and it can only be assembled by hand. Therefore, if the positioning is not accurate, the floating effect will be uneven and the clamping effect will be affected. In addition, the elastic support effect of the spring will weaken over time, and the elasticity of the support column is relatively weak compared to the elastic structure during use. Therefore, the stability of the floating device composed of the elastic rubber seat in the prior art is poor. Finally, the elastic member in the prior art is a separate layer in the laminated structure of the heating plate assembly. In order to achieve good elasticity, the thickness of the elastic member needs to be thick enough, so that the overall heating plate assembly is thick, which is not conducive to thinning. SUMMARY

[0040] As Figures 1-3As shown, a floating device provided in Embodiment 1 of the present invention includes a heat-conducting sheet 1, a heat-conducting plate, and a floating component. The floating component consists of two elastic components 2, which are respectively disposed on both sides of the heat-conducting plate and longitudinally elastically support the heat-conducting plate. The elastic components 2 and the heat-conducting sheet 1 are assembled through a connecting structure, and the top surface of the heat-conducting plate and the bottom surface of the heat-conducting sheet 1 are in contact with each other for heat conduction. In this embodiment, the heat-conducting sheet 1 is made of copper, which has high thermal conductivity and is widely used. The heat-conducting plate is made of aluminum. In this embodiment, the heat-conducting plate is configured to be composed of two support plates 3 arranged side by side along the long axis of the heat-conducting sheet 1, with a gap between the two support plates 3 allowing them to move relative to each other, so that the two support plates 3 can move relative to each other independently, improving the elastic floating effect. When the heat-conducting plate is a single integral structure, the elastic floating effect can also be achieved. By using two support plates 3, its elastic floating effect can be further improved. When there are three support plates 3, four support plates 3, etc., there are more independent floating ranges.

[0041] like Figures 1-3 As shown, the elastic member 2 in this embodiment 1 has a top 4, an elastic connecting portion 5, and a bottom 6 connected sequentially from top to bottom. The elastic connecting portion 5 is used to deform when the top 4 is subjected to external force, thereby shortening the distance between the top 4 and the bottom 6. Specifically, there are multiple elastic connecting portions 5, which are spaced apart to connect the aforementioned top 4 and bottom 6. The top 4, elastic connecting portion 5, and bottom 6 are all integrally injection molded elastic materials. In this embodiment, the elastic member 2 is an independent component. The function of the elastic member 2 is to provide individual elastic support for the two edges 10 of the heat-conducting plate. Therefore, based on this, two elastic members 2 can be made with a connecting portion, such as an integrally molded silicone body or a rubber body, which are non-metallic materials with controllable elasticity and injection molding capability. Therefore, the two elastic members 2 can also be referred to as one elastic member 2. In addition, the elastic member 2 can also be manufactured such that only the elastic connecting portion 5 has elastic force, while the top 4 and bottom 6 are made of rigid materials, which can also achieve elastic support for the heat-conducting plate and the heat-conducting sheet 1. However, the aforementioned feasible solutions are all variations within the scope of protection of this application and fall within the scope of protection of this application. The elastic connecting part 5 referred to in this application is a structure that is arc-shaped from top to bottom, thus possessing elastic deformation capability based on its elastic properties, and can also be called an arc-shaped connecting part. Of course, in other embodiments, processing the arc-shaped structure can improve the elastic deformation capability, and the S-shaped structure also has the elastic deformation capability. It should be noted that the elastic connecting part 5 itself has the elastic deformation capability due to the elastic material properties. Shaping it into an arc shape or S-shape is only to further enhance its elastic deformation capability, and it is not that its shape is specially restricted to reflect the elastic deformation capability. Of course, through experiments, it has been found that the arc shape is simple and can better exert the elastic deformation capability, and is therefore a better technical solution.

[0042] As Figures 1-3 shown in the embodiment 1, according to the position of the elastic member 2 on the heat-conducting plate, the heat-conducting sheet 1 is integrally formed with connecting buckles 7 on the left and right sides, and the corresponding elastic member 2 is provided with a through connecting hole 8, and the connecting buckle 7 is buckled with the connecting hole 8 to form a connecting structure. Since the elastic member 2 is of flexible material, in order to further strengthen the connecting strength of the connecting buckle 7 and the connecting hole 8, and ensure the reliability of the connecting assembly between the elastic member 2 and the heat-conducting sheet 1, the connecting buckle 7 is assembled by bending after being inserted into the connecting hole 8.

[0043] As Figures 1-3 shown in the embodiment 1, the heat-conducting plate has a hole position 9 for accommodating the heat-generating body in the center, and the heat-conducting plate has a transverse edge 10 on both sides, the edge 10 abuts against the top surface of the elastic member 2, the inside of the top surface of the elastic member 2 has a limiting groove 11 lower than the outside, and the edge 10 has a longitudinal limiting convex edge 12 limited in the limiting groove 11, so that the support of the elastic member 2 to the heat-conducting plate is more reliable and stable, and the hole position 9 is between the two elastic members 2. After the heat-generating body is powered on, the heat emitted by the heat-generating body is transmitted to the heat-conducting plate, and the heat-conducting plate transmits the heat to the heat-conducting sheet 1 through contact heat transfer, and the heat-conducting sheet 1 outputs heat as a contact surface. The heat-conducting sheet 1 and the heat-conducting plate are both supported by the elastic member 2, which can reduce the transmission of heat to other components and effectively avoid the transmission path of heat.

[0044] As Figures 1-3 shown in the embodiment 1, the inside of the top surface of the elastic member 2 has a recess 13 lower than the outside, and the edge 14 of the heat-conducting sheet 1 is embedded in the recess 13 to form a sealing or edge covering of the edge 14 of the heat-conducting sheet 1 by the elastic member 2, and when the top 4 of the elastic member 2 is of elastic material, the sealing or edge covering of the edge 14 can be more effectively realized.

[0045] As Figures 4-5 shown in the embodiment 1 of the hair styling device, the first clamp head 15 and the second clamp head 16 can be opened and closed relative to each other, wherein the first clamp head 15 and the second clamp head 16 each have a accommodating groove 17, and a floating device as described in the foregoing embodiment is assembled in the accommodating groove 17, and the two ends of the floating device are assembled in the accommodating groove 17 through a heat insulation plate 18; specifically, the heat insulation plate 18 is inserted and assembled at the two ends of the heat-conducting plate, the heat insulation plate 18 is transversely limited at the two ends of the accommodating groove 17, and the heat insulation plate 18 can limit the movement range of the floating device in the accommodating groove 17. In order to simplify the assembly structure and improve the assembly reliability of the floating device in the accommodating groove 17, a mounting groove 19 is arranged in the accommodating groove 17, and a mounting protrusion 20 is arranged on the bottom surface of the elastic member 2 of the floating device, and the mounting protrusion 20 is limited in the mounting groove 19.

[0046] As Figures 6-9The illustration shows Embodiment 2 of the present invention, which differs from Embodiment 1 in that the heat-conducting sheet 1 and the heat-conducting plate are assembled via a connecting structure. In Embodiment 2, the heat-conducting sheet 1 is provided with a connecting portion 21, which is bent and fastened to the edge 10 of the heat-conducting plate to form the connecting structure. To enhance the reliability of the assembly between the connecting portion 21 and the heat-conducting plate, the connecting portion 21 may be provided with a snap hole 22, and the corresponding position of the heat-conducting plate is provided with a protrusion corresponding to the snap hole 22. After bending, the connecting plate fits the snap hole 22 onto the protrusion to strengthen the connection.

[0047] To enhance the assembly reliability between the connecting part 21 and the heat-conducting plate, prevent misalignment along the long axis between the heat-conducting sheet 1 and the heat-conducting plate, and ensure the stability of their relative positions, the bottom surface of the edge 10 can have an upper recess 23. The connecting part 21, after being bent from the top surface to the bottom surface of the edge 10, is at least partially embedded in the upper recess 23, thus limiting its position. Furthermore, to enhance the stability of the relative position between the elastic member 2 and the heat-conducting sheet 1, the top surface of the elastic member 2 has a lower recess 24. The connecting part 21, after being bent from the top surface to the bottom surface of the edge 10, is at least partially embedded in the lower recess 24, thus providing mutual limiting between the connecting part 21 and the elastic member 2 after bending. This structure enhances the assembly reliability of the overall floating device and is simple and easy to assemble.

[0048] like Figures 6-10 As shown, the hair styling device of Embodiment 2 of the present invention differs from the hair styling device of Embodiment 1 in that: a fixed base 25 made of metal stamping is assembled in the receiving groove 17. The fixed base 25 abuts against the bottom surface of the elastic member 2 to provide support for the elastic member 2. The heat-conducting plate is movably assembled with the fixed base 25 through an assembly structure. The fixed base 25 made of metal stamping can reduce the thickness of the fixed base 25, strengthen the fixed base 25, and integrally stamped to form a more reliable buckle 28 and limiting part 29. The fixed base 25 has longitudinally extending support parts 26 at both ends. The support parts 26 abut against the inner upper wall of the clamp forming the receiving groove 17 to limit the assembly position of the fixed base 25 in the receiving groove 17.

[0049] In order to better limit the floating of the heat-conducting plate in the accommodating groove 17, the heat-conducting plate of the second embodiment is provided with edges 27 extending along the long axis on both sides, the fixing seat 25 is provided with a buckle part 28 buckling the upper surface of the edge 27, the buckle parts 28 on both sides and the inner bottom of the fixing seat 25 form a cavity limiting the heat-conducting plate, and the buckle part 28 and the edge 27 form an assembly structure for limiting the floating range of the heat-conducting plate, i.e. the range of floating up and down. Before the floating device is not under pressure, the heat-conducting plate has a tendency to float up due to the elastic support of the elastic member 2, and under the joint action of the buckle part 28 and the edge 27, the heat-conducting plate is kept at the highest position of floating up.

[0050] In order to ensure that the elastic member 2 is not easy to deviate and deform in the longitudinal direction during the process of providing elastic support, the part of the second embodiment extending from the fixing seat 25 to form the aforementioned buckle part 28 and the side part 30 of the fixing seat 25 form a limiting part 29 for embedding at least part of the bottom of the elastic member 2 to limit, which can be continuous along the long axis or intermittently arranged.

[0051] Those skilled in the art should understand that the technical features of the above-described embodiments can be combined arbitrarily, and in order to make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, however, as long as the combinations of the technical features do not exist contradictory, it should be considered that it is within the scope of the present application.

[0052] The above-described embodiments only express several embodiments of the present application, which are described in detail and in detail, but should not be understood as limiting the scope of the patent. It should be noted that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
