However, in the actual use process, only the electric heating function is needed, etc. However, the processing body needs to be supported and fixed to be used. It is particularly urgent to develop a heating element structure to replace the self-heating metal carrier.

[0003] The existing self-heating metal carrier structure has the following problems:

[0010] To solve the above technical problems, the technical solution adopted by the utility model is: an electric heating element with an independent support structure, including a support structure and a heating carrier located in the support structure. The support structure includes a housing, a support plate and an electrode.

[0016] Further, slot holes for fixing the first electrode and the second electrode are formed in the outer shell, and ceramic materials are arranged between the first electrode or the second electrode and the slot holes.

[0017] Compared with the prior art, the beneficial effects of the present utility model include: by integrating the support structure with the heating carrier, there is no need to add a metal carrier for support during the production process, which reduces the production cost.

[0023] It is easy to understand that according to the technical solution of the present utility model, without changing the essential spirit of the present utility model, those of ordinary skill in the art can propose various structural forms and implementation methods that can be mutually replaced. Therefore, the following specific embodiments and drawings are only illustrative descriptions of the technical solution of the present utility model, and should not be regarded as all of the present utility model or as a limitation or restriction on the technical solution of the present utility model.

[0024] As Figure 1 shown, an electric heating element with an independent support structure includes a support structure and a heating carrier 1 located within the support structure. The support structure includes a housing 2, a support plate 3, and electrodes. The housing 2 is a cylinder. The heating carrier 1 is fixed within the housing 2. The support plate 3 is fixed at both ends of the housing 2. The electrodes penetrate the side wall of the housing 2 and contact the heating carrier 1. The heating carrier 1 is fixed within the support structure, and the electrodes contact the heating carrier 1. The electrodes are metal structures and can directly supply power to the heating carrier 1, enabling the heating carrier 1 to generate heat by itself.

[0025] In some embodiments, the electrodes include a first electrode 4 and a second electrode 5. The first electrode 4 and the second electrode 5 are oppositely arranged on the housing 2, and both the first electrode 4 and the second electrode 5 penetrate the housing 2 and communicate with the heating carrier 1. The first electrode 4 can be used as the positive electrode and the second electrode 5 can be used as the negative electrode to supply power to the aforementioned heating carrier 1, enabling the heating carrier 1 to generate heat by itself.

[0026] In some other embodiments, the support structure includes a first electrode 4 and a second electrode 5. The first electrode 4 penetrates the housing 2 and communicates with the heating carrier 1, while the second electrode 5 is fixed on the housing 2 and the end of the second electrode 5 contacts the inner wall of the housing 2. Taking the first electrode 4 as the positive electrode, and since the second electrode 5 is in communication with the housing 2 and the heating carrier 1 contacts the inner wall of the housing 2, the heating carrier 1 and the housing 2 are in a conductive state, and the second electrode 5 in communication with the housing 2 can also be in conduction with the heating carrier 1. In this way, the second electrode 5 can be used as the negative electrode, and the second electrode 5 can be arranged at any position on the housing 2 other than where the first electrode 4 is located, and the second electrode 5 can be used as the negative electrode.

[0027] It is worth noting that slot holes for fixing the first electrode 4 and the second electrode 5 are provided on the housing 2. The slot holes penetrate the thickness direction of the housing 2, and a ceramic material is provided between the first electrode 4 or the second electrode 5 and the slot holes to ensure insulation between the metal electrode and the slot holes, so that only the ends of the first electrode 4 or the second electrode 5 are in communication with the housing 2 or the heating carrier 1, ensuring safety.

[0028] The structure of the support plate 3 is as Figure 2As shown, it includes a first ring and a second ring with different radii, and the radius of the first ring is greater than that of the second ring. A plurality of columns are used to fix the second ring inside the first ring to form a support plate, and the outer edge surface of the first ring is welded to the inner wall of the housing 2 as a whole.

[0029] As Figure 3 shown, the heating carrier 1 will be specifically described below. The heating carrier 1 is composed of multiple groups of cores. Each group of cores is composed of a flat belt and a corrugated belt. The corrugated belt is fixedly arranged between two flat belts. The multiple groups of cores are wound around the central point in a clockwise or counterclockwise direction to form the heating carrier 1. In this embodiment, taking two groups of cores as an example, during the winding process, first fold the core in half, and then arrange the folding points of the two groups of cores in opposite directions based on the aforementioned central point. The folding points of the two groups of cores are centrosymmetric based on the aforementioned central point. Then, the two groups of cores are also wound in the counterclockwise direction to obtain the heating carrier 1.

[0030] It is worth noting that as Figure 1 and Figure 3 shown, a support column 6 can be arranged between the two groups of cores to prevent contact between the two groups of cores after winding, and a support column 6 can also be arranged inside each group of cores to avoid contact inside the cores after winding. And a support column 6 is also fixedly arranged between the heating carrier 1 and the support disk to separate the heating carrier 1 from the support plate 3; the aforementioned support columns 6 used are all ceramic columns.

[0031] In the present utility model, the heating carrier 1 and the support structure are combined into one body, without the need to add a subsequent support metal carrier, reducing the production and replacement costs. And because there is no support carrier absorbing heat, the heat conversion efficiency can be improved, realizing modular multiple uses and replacements. When the heat conversion efficiency is improved and it is applied to tail gas treatment, it can make the tail gas heat up quickly, make the subsequent catalytic converter ignite quickly, and shorten the ignition time; while the heating carrier 1 is independently supported by the support structure, and the actual area of the heating body is small, reducing the back pressure.

[0032] The technical scope of the present utility model is not limited to the content described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of the present utility model, and these deformations and modifications should all fall within the protection scope of the present utility model.
