Description

Technical Field

[0001] The utility model relates to the technical field of electrothermal technology, in particular to a limiting net for a flexible heating film and a far-infrared energy generator. Background Art

[0002] Electric heaters are commonly used heating devices. Electric heaters using flexible heating films as heat sources have thinner sizes and lighter weights, and can also be used for physiotherapy, providing a better user experience.

[0003] Since the heating film is composed of a composite of polymer materials, when it is working with heat, the increase in temperature will cause the polymer materials to deform due to the thermal expansion effect, resulting in the deformation of the heating film. To ensure its flatness, the front and back of the heating film need to be limited.

[0004] In the past, hard materials were mostly used for limiting, such as metal strips or high-temperature resistant plastic strips. Such designs have the following disadvantages:

[0005] 1. Metal strips have good rigidity, but high costs;

[0006] 2. High-temperature resistant plastic strips have lower costs than metal strips, but when their thickness is small, they cannot meet the limiting effect. Therefore, they need to have a certain thickness, which will block the infrared rays radiated by the heating film.

[0007] 3. Both high-temperature resistant plastic strips and metal strips have fixed sizes, cannot meet the needs of different size limitations, and have poor versatility. Summary of the Invention

[0008] The technical problem to be solved by the utility model is to provide a limiting net for a flexible heating film and a far-infrared energy generator, which have low use costs, are convenient to install, and have good versatility.

[0009] To solve the above technical problem, the utility model provides a limiting net for a flexible heating film, including a soft rope and a plurality of positioning columns. The plurality of positioning columns are arranged around the flexible heating film and cooperate to form a limiting area. The soft rope is tightened in the limiting area in cooperation with the positioning columns to form a limiting plane.

[0010] Further, the soft rope is wound and tightened on a plurality of positioning columns in the limiting area to form a limiting plane.

[0011] Further, the limiting plane is arranged on the front surface and / or the back surface of the flexible heating film.

[0012] Further, the soft rope is woven to form a mesh surface, and a plurality of pulling sections are arranged on the periphery of the mesh surface. The plurality of pulling sections cooperate with the plurality of positioning columns to tighten the mesh surface to form a limiting plane.

[0013] Further, the flexible rope is made of a fiber material, and the fiber is a polymer material or an inorganic fiber material.

[0014] Further, a metal wire is arranged inside the flexible rope.

[0015] Further, both ends of the flexible rope are tightly connected through a cable tie, a tension spring or a tightener.

[0016] Further, a connecting ring part is arranged at the end of the flexible rope.

[0017] Further, an anti - detachment convex part is arranged at the top of the positioning column.

[0018] Advantages of the utility model:

[0019] 1. The flexible rope is fixed on multiple positioning columns, which can effectively form a limiting plane. The operation is convenient, and the shape of the flexible rope can be adaptively planned and set according to the limiting needs, with strong versatility.

[0020] 2. The flexible rope has a smaller weight, that is, the additional weight of the entire far - infrared energy generator is effectively reduced, and the manufacturing cost is low.

[0021] 3. The surface of the flexible rope can be effectively insulated and has an adiabatic effect, which can ensure the safety of use and will not cause damage to the surface of the heating film, improving the product quality. Description of the drawings

[0029] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the embodiments cited do not limit the present utility model.

[0030] Referring to Figures 1 to 5 As shown, an embodiment of the limiting net of the flexible heating film of the present utility model includes three soft ropes 1 and six positioning columns 2. The six positioning columns are arranged in two rows on both sides of the flexible heating film. A plurality of positioning columns are arranged around the flexible heating film 3 and cooperate to form a limiting area 4. The soft ropes are tightened in the limiting area in cooperation with the positioning columns to form a limiting plane. There are two limiting planes, which are respectively located on the two surfaces of the flexible heating film. The positioning columns are arranged on the skeleton 11 of the electric heater to form an effective support for the limiting plane.

[0031] During assembly, first, the first soft rope is laid out. As Figure 4 shown, taking the four positioning columns in the upper part as the fulcrums to form the first limiting area, and the first soft rope is wound around the four positioning columns to form a structure of X layout in the limiting area; then, the second soft rope is laid out. As Figure 5 shown, taking the four positioning columns in the lower part as the fulcrums to form the second limiting area, and two of the positioning columns share with two of the positioning columns in the first limiting area. The second soft rope is wound around the four positioning columns to form a structure of X layout in the limiting area; then, the third soft rope is laid out. As Figure 5 shown, taking the four positioning columns in the lower part as the fulcrums to form the third limiting area, and two of the positioning columns share with four of the positioning columns in the first limiting area and the second limiting area. The third soft rope is wound around the four positioning columns to form a structure of X layout in the limiting area; thus, three limiting structures are obtained, which cooperate to form a limiting plane with a net-like distribution in the plane, playing a role in limiting the flexible heating film.

[0032] The above-mentioned soft rope is made of fiber material and has good heat insulation effect. The fiber is a polymer material or an inorganic fiber material, such as aramid or methylene fiber, etc. In order to improve the tensile strength of the soft rope, a metal wire can be arranged inside the soft rope, and the soft rope completely encloses the metal wire without leakage, so there is no risk of electric conduction.

[0033] And both ends of the soft rope are tightly connected through a tie strap, a tension spring or a tightener 7. The tie strap has a low cost and is convenient to operate; the tension spring has the ability of deformation and stores energy through its own deformation, and can always keep the soft rope in a tightened state; the tightener can adjust the stiffness of the limiting plane at any time, is convenient to operate, and even if the soft rope is loose, it can be tightened again by operating, which is convenient for maintenance. Based on the above connection method, a connection ring part is arranged at the end of the soft rope, which is convenient to be fixed by a tie strap, a tension spring or a tightener.

[0034] Since the soft rope is tightened after passing around the positioning post, there is a risk of slipping in the axial direction of the positioning post. Therefore, an anti-slip convex portion 8 is provided at the top of the positioning post. After the soft rope is tightened, it clings to the surface of the positioning post, and the axial movement of the soft rope is restricted by the anti-slip convex portion, so that the anti-slip effect can be achieved.

[0035] In one embodiment, in the above solution, the soft rope forms a limiting plane by winding around the positioning post. Of course, a net surface 5 can also be formed by pre-weaving the soft rope in advance, and then the net surface is fixedly matched with the positioning post, which can also form an effective limiting plane. Refer to Figure 6 As shown, taking four positioning posts as an example, pulling sections 6 that can be used for fixation are provided at the four corners of the net surface. The pulling sections can be directly tied and fixed to the corresponding positioning posts, and the four pulling sections cooperate with the four positioning posts to tighten the net surface to form a limiting plane.

[0036] To ensure the tightening effect of the net surface, the pulling sections can be pulled in pairs, that is, in Figure 6 , after the two pulling sections on the left side respectively pass around the positioning post, both ends are tightened and fixed. After the two pulling sections on the right side also respectively pass around the positioning post, both ends are tightened and fixed, so as to flatten the net surface.

[0037] In one embodiment, refer to Figure 7 As shown, a structure for arranging the limiting plane in an S shape is also provided. By continuously winding a soft rope around multiple positioning posts, the number of positioning posts can be increased to 8, 10, etc. All the positioning posts cooperate to form a limiting area at the same time. After the soft rope is wound, a relatively tight limiting structure can be formed, and the limiting effect is better.

[0038] The soft rope of the present utility model can adopt very thin silk threads, so that the prepared limiting net hardly blocks the emission of far-infrared rays, and does not affect the temperature rise and temperature uniformity of the heating element; the limiting net can be arranged on the front and back surfaces of the heating film; it can also be independently arranged on one side of the flexible heating film according to needs, which has high flexibility.

[0039] The above embodiments are only the preferred embodiments cited to fully illustrate the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or transformations made by those skilled in the art on the basis of the present utility model are all within the protection scope of the present utility model.
