Technical Field

[0001] This utility model relates to the field of electric ceramic infrared heating tube technology, and in particular to an electric ceramic infrared heating tube. Background Technology

[0002] Ceramic infrared heaters consist of a resistance heat conductor fully embedded in a suitable ceramic material. Because it is fully embedded in the ceramic, the energy generated by the heat conductor can be transferred to the surrounding material, which not only prevents the heat conductor from overheating but also extends its service life. The material used to embed the heat conductor must be insulating and have good absorption and radioactivity within the set infrared radiation range. To meet this requirement, ceramic infrared heaters can be made into different geometries. The main body of the ceramic infrared heater is ceramic, and a portion of its surface is used as a radiating surface and a heating coil is integrated. For ceramic infrared heaters, a thermocouple can also be fixed adjacent to the heat conductor.

[0003] In existing technologies, the connection between the heat conductor and the wire is not protected and is easily damaged when exposed to the outside. It is also easily broken by external force. To address this, we propose an electrothermal ceramic infrared heating tube. Utility Model Content
