Problems solved by technology

With the structure of the inner electrode lead ceramic heating rod, the welding point of the electrode lead is on the inner surface of the curled ceramic sheet, both inside and outside are suspended, and the tensile performance of the electrode lead is seriously affected.
In the manufacturing process, the welding operation space is limited in the welding groove, and the end cap of the assembly rod needs to be glued, which affects the production efficiency

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...

Abstract

The invention relates to a ceramic heating rod with a ceramic core and electrode leads and a production method of the ceramic heating rod. The production method is applied to heating of warm water ofa smart toilet, flow of a water heater, electric soldering iron and a hair curler and production of the ceramic heating rod. The ceramic heating rod with the ceramic core and the electrode leads is characterized in that a cylindrical ceramic lining core is provided with a first electrode lead cavity and a second electrode lead cavity; the first electrode lead cavity extends inwards from the end surface of the cylindrical ceramic lining core, passes through a first electrode lead weld leg cavity and then passes outside from a first connection hole in a side wall; the second electrode lead cavity extends inwards from the end surface of the cylindrical ceramic lining core, passes through a second electrode lead weld leg cavity and then passes outside from a second connection hole in the sidewall; the inner surface of the first electrode lead weld leg cavity is provided with a first electrode lead weld leg cavity conducting material sintering layer; and the inner surface of the second electrode lead weld leg cavity is provided with a second electrode lead weld leg cavity conducting material sintering layer. The ceramic heating rod has the advantages that the purposes of a first connecting plate material sintering layer and a second connecting plate material sintering layer are changed, and the tensile property and the brazing efficiency of the electrode leads are improved.
