Description

Technical Field

[0001] The invention relates to the technical field of ignition of gas appliances, in particular to a direct-plug ignition device suitable for a dual-purpose stove. Background Art

[0002] Due to the high temperature characteristics of the existing electric ignition furnace, the igniter is usually set far away from the furnace body to prevent the igniter from being damaged due to the high temperature of the furnace body being transferred to the igniter due to long-term use of the furnace body, causing the insulating material to melt and fail. The specific reason is: the high-voltage discharge needle is located in the combustion chamber inside the furnace body, and the high temperature of combustion will be directly transferred to the discharge needle and then conducted to the igniter by the wiring harness. Therefore, the existing electric ignition device uses a wire to connect to the high-voltage discharge needle. The wire between the high-voltage discharge needle and the igniter needs to extend a long distance, but when the wire is too long, it will affect the pulse ignition energy and cause high-voltage discharge instability; it is also susceptible to electromagnetic interference or mechanical wear.
