Abstract

This invention relates to an electric ceramic body with a central hole including a ceramic electric body and a central hole through up and down, and the electric body includes an outer resistant layer made of conductive ceramic material, an insulation layer and an inside conductive layer orderly placed from outside to inside, a through hole is set at the top of the insulation layer, the internal diameter of the through hole is greater than the internal diameter of the upper section of the central hole, part materials of the internal and the outside resistant layers are connected at the through hole of the insulation layer used in heating and igniting an engine.

Description

technical field [0001] The invention belongs to the technical field of electric heaters characterized by the composition and properties of materials. Background technique [0002] The prior art all-ceramic electric heater can be used for heating and ignition. The disadvantage is that the existing technology is a solid body, which cannot provide a channel that can detect and output a signal reflecting the pressure of the medium. Contents of the invention [0003] The technical problem to be solved is to provide an all-ceramic electric heater with a central hole and a channel capable of detecting and outputting a reflection medium pressure. [0004] The technical solution to solve its technical problems is as follows: an all-ceramic electric heating body with a central hole, including an all-ceramic electric heating body and a central hole that penetrates up and down; an all-ceramic electric heating body includes an outer resistance layer made of conductive ceramic material...
