Safe silicon nitride igniter

Abstract

The invention discloses a safe silicon nitride igniter. The safe silicon nitride igniter comprises an insulating ceramic, a storing groove is formed in the internal center of the insulating ceramic ina penetrating mode, and a silicon nitride ceramic heating element is embedded in the storing groove. According to the safe silicon nitride igniter, a porous ceramic plate, a copper wire net and an energizing pin are arranged, the heat can be isolated well, the temperature is prevented from being transferred into the insulating ceramic, the temperature is concentrated on the insulating ceramic, the normal work of the internal wires is affected, and the safety can be improved better; and when the silicon nitride ceramic heating element breaks, the copper wire net can play a temporary connectionrole, and the normal use of other equipment is affected due to the splashing during the fragmentation of the silicon nitride ceramic heating element is avoided; and the later use is affected due to the entangling of the outer wires during installation can be further avoided well, meanwhile, the damaged outer wires can be replaced more conveniently, and the better use prospects are brought.

Description

technical field [0001] The invention relates to the field of igniters, in particular to a safe silicon nitride igniter. Background technique [0002] The excellent performance of silicon nitride igniter is suitable for the working environment of high temperature, high speed and strong corrosive medium often encountered by modern technology, but with the development of science and technology, people have higher and higher requirements for silicon nitride igniter, resulting in the traditional The existing silicon nitride igniter can no longer meet people's needs, and people need a safer and more convenient silicon nitride igniter; the existing silicon nitride igniter has certain disadvantages in use, first of all, it cannot be well isolated Heat, when used for a long time, the wire inside the insulating ceramic is easy to be damaged by heat. Secondly, when the silicon nitride ceramic heating element is damaged by force, the fragments cannot be fixed well, and the damage will s...

[0002] The excellent performance of silicon nitride igniter is suitable for the working environment of high temperature, high speed and strong corrosive medium often encountered by modern technology, but with the development of science and technology, people have higher and higher requirements for silicon nitride igniter, resulting in the traditional The existing silicon nitride igniter can no longer meet people's needs, and people need a safer and more convenient silicon nitride igniter; the existing silicon nitride igniter has certain disadvantages in use, first of all, it cannot be well isolated Heat, when used for a long time, the wire inside the insulating ceramic is easy to be damaged by heat. Secondly, when the silicon nitride ceramic heating element is damaged by force, the fragments cannot be fixed well, and the damage will splash and fall easily. It affects the normal use of other equipment. Finally, when the existing silicon nitride igniter is installed and used, the silicon nitride igniter needs to be fixed, and the external wire is easy to be entangled. At the same time, the external wire is easily damaged by external influences. Timely replacement will bring a certain impact. Therefore, we propose a safe silicon nitride igniter
