Ceramic heating rod with ceramic core and electrode leads and production method of ceramic heating rod

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.

Description

technical field [0001] The invention relates to a ceramic heating rod with a ceramic core electrode lead wire and a manufacturing method thereof, which is applied to warm water of an intelligent toilet, water flow of a water heater, heating of an electric soldering iron, a hair curler and production of a ceramic heating rod. Background technique [0002] A ceramic heating rod using electric energy, including a cylindrical ceramic lining core and a curled ceramic sheet tightly attached to the outer surface of the cylindrical ceramic lining core through sintering. The inner surface of the curled ceramic sheet has a heating circuit and the first conductive circuit and the second conductive circuit respectively connected to the two ends of the heating circuit; the outer surface of the curled ceramic sheet has a sintered layer of the first land material and a sintered layer of the second land material. The first conductive circuit is sintered and electrically connected to the sin...

AI Technical Summary

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
