Embodiment Construction
[0049] A ceramic heating rod with a ceramic core electrode lead, comprising: (a) a cylindrical ceramic lining core (6) and a curled ceramic sheet (1) tightly attached to the outer surface of the cylindrical ceramic lining core by sintering; (b) the first electrode lead ( 3) and the second electrode lead (4); the first land material sintered layer (19), first conductive circuit (18), heating circuit (17), second Conductive circuit (21), second connection pad material sintered layer (20). The improvement of the invention is that the cylindrical ceramic liner has a first electrode lead cavity and a second electrode lead cavity.
[0050] The first electrode lead cavity extends inwardly from the end surface of the cylindrical ceramic lining core, passes through the first electrode lead fillet cavity (9), and passes through the first connection hole (8) on the side wall. This is the cavity distribution and cavity orientation of the first electrode lead cavity in the cylindrical cer...
