Description

Technical Field

[0001] This utility model relates to the field of ignition devices, and in particular to a series ignition element and a series ignition device. Background Technology

[0002] Ignition devices are usually equipped with a heating wire. The heating wire reaches a very high temperature after heating, which can quickly ignite the ignition material and achieve rapid ignition.

[0003] In existing technologies, ignition elements employ a single-substrate structure with copper bodies arranged on both the front and back sides. These copper bodies are fabricated using PCB etching, a process that precisely removes unwanted copper foil using chemical methods to create the desired circuit pattern. A fuel-containing cavity is formed on the front side of the single substrate, with a heating wire spanning the cavity and connected to the corresponding copper body. In this structure, both the front and back sides of the single substrate require separate PCB etching processes to form copper bodies. After one side is completed, the other side must be fabricated. The entire manufacturing process is cumbersome, time-consuming, and inefficient, increasing the production cost of the ignition element. Furthermore, the heating wire is directly positioned on the surface of the cavity, increasing the time required for complete ignition of the fuel within the cavity and resulting in a slower ignition speed.

[0004] Therefore, it is necessary to design a new technical solution to solve the above problems. Utility Model Content
