Description

Technical Field

[0001] This utility model belongs to the field of ceramic heating element technology, and relates to a thickened irregular-shaped ceramic heating element. Background Technology

[0002] Traditional heating elements mostly use metal as a base, but in high-temperature and humid environments, metal is prone to corrosion or localized overheating, which reduces the safety and lifespan of the equipment. In recent years, heating elements made of ceramic materials have received widespread attention due to their high temperature resistance, corrosion resistance and high insulation.

[0003] Chinese utility model patent with authorization announcement number CN208806988U discloses a ceramic heating element. The ceramic heating element is a plate-shaped structure composed of an upper ceramic plate, a lower ceramic plate, a heating part, and a lead wire. The heating part is located between the upper and lower ceramic plates and includes a plurality of heating resistors. However, the ceramic heating element in this technical solution is rectangular, which may cause inconvenience for workers when it needs to be installed into a triangular irregular hole. Summary of the Invention

[0004] To address the aforementioned problems, this utility model proposes a thickened irregularly shaped ceramic heating element, which effectively solves the problems in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a thickened irregularly shaped ceramic heating element, comprising an upper ceramic element and a lower ceramic element, both of which are triangular. A tungsten paste heating circuit is provided on the opposite sides of the upper and lower ceramic elements, and a power-conducting component connected to both ends of the tungsten paste heating circuit is provided on the lower side of the lower ceramic element.

[0006] Furthermore, the power-conducting component includes two electrode holes on the lower ceramic plate, the two electrode holes being located at both ends of the tungsten paste heating circuit, and electrode plates sandwiched between the upper and lower ceramic plates at both ends of the tungsten paste heating circuit, with power-conducting wires connected to the electrode plates disposed in the electrode holes.

[0007] Furthermore, the energized conductor includes a nickel wire conductor and a Teflon sleeve covering the outside of the nickel wire conductor, with one end of the nickel wire conductor welded and fixed to the electrode plate.

[0008] Furthermore, a dotted adhesive is provided inside the electrode hole.

[0009] Furthermore, the upper ceramic sheet and the lower ceramic sheet are provided with a rectangular positioning hole.

[0010] Furthermore, the thickness of both the upper and lower ceramic sheets is 1.25 cm.

[0011] Furthermore, the corners of both the upper and lower ceramic sheets are rounded.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention improves the ease of installation for workers when placing the ceramic heating element into the triangular hole by using a triangular design of the upper ceramic plate, lower ceramic plate, and tungsten paste heating circuit. The positioning hole enables the ceramic heating element to be positioned during installation, further improving the ease of installation. The power supply component enables the tungsten paste heating circuit to be powered, ensuring the reliability of the tungsten paste heating circuit during heating. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1 , Figure 2 , Figure 3 As shown, a thickened irregularly shaped ceramic heating element includes an upper ceramic sheet 1 and a lower ceramic sheet 2. Both the upper ceramic sheet 1 and the lower ceramic sheet 2 are triangular. Tungsten paste heating circuits 3 are printed on the opposite sides of the upper ceramic sheet 1 and the lower ceramic sheet 2. A power-conducting component connected to both ends of the tungsten paste heating circuit 3 is provided on the lower side of the lower ceramic sheet 2.

[0020] In this embodiment, the power-conducting component includes two electrode holes 201 on the lower ceramic plate 2. The two electrode holes 201 are located at both ends of the tungsten paste heating circuit 3. Both ends of the tungsten paste heating circuit 3 are provided with electrode plates 4 sandwiched between the upper ceramic plate 1 and the lower ceramic plate 2. Power-conducting wires connected to the electrode plates 4 are provided in the electrode holes 201.

[0021] In this embodiment, the energized conductor includes a nickel wire conductor 6 and a Teflon sleeve 5 covering the outside of the nickel wire conductor 6. One end of the nickel wire conductor 6 is welded and fixed to the electrode plate 4.

[0022] In this embodiment, a dot adhesive 7 is provided inside the electrode hole 201.

[0023] In this embodiment, the upper ceramic sheet 1 and the lower ceramic sheet 2 are provided with a rectangular positioning hole 8.

[0024] In this embodiment, the thickness of both the upper ceramic sheet 1 and the lower ceramic sheet 2 is 1.25 cm.

[0025] In this embodiment, the corners of both the upper ceramic sheet 1 and the lower ceramic sheet 2 are rounded.

[0026] The working principle of this technical solution is as follows: During production, the staff prints the tungsten paste heating circuit 3 onto the opposite sides of the upper ceramic plate 1 and the lower ceramic plate 2. Then, the staff places the electrode plate 4 at the end of the tungsten paste printed circuit. After placement, the upper ceramic plate 1 and the lower ceramic plate 2 are fixedly connected together by high-temperature sintering. After sintering, the staff welds one end of the power-carrying wire to the electrode plate 4 and fixes it with glue 7 to prevent the power-carrying wire from detaching from the electrode plate 4 during use, thus ensuring the reliability of the ceramic heating plate during use.

[0027] When in use, the thickness of the upper ceramic plate 1 and the lower ceramic plate 2 is increased by one-quarter compared to traditional ceramic heating plates, which improves the protective capability of the ceramic heating plate. In addition, the positioning holes 8 on the upper ceramic plate 1 and the lower ceramic plate 2 guide the ceramic heating plate during installation, which improves the convenience of the staff during installation. At the same time, the rounded corner design of the upper ceramic plate 1 and the lower ceramic plate 2 prevents the edges of the upper ceramic plate 1 and the lower ceramic plate 2 from cutting the staff, thus improving the safety of the ceramic heating plate.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
