The electric gas stove has high energy utilization efficiency and fast heating speed, which can shorten the cooking time. During use, no gas is required, avoiding the risks of gas leakage and explosion. At the same time, multiple safety protection mechanisms ensure safety during use, and it has been applied to a certain extent in the field of household equipment. Existing electric gas stoves can basically meet daily use requirements. However, in the actual use process of the current fire outlet devices such as electric gas stoves and electric gas water heaters, the ignition needle needs to be inserted into a ceramic twist nut for fixation and the wire needs to be welded. Moreover, most of the air outlet slots of the ignition device are opened on the side wall of the ceramic. The on-site assembly process is cumbersome, resulting in low process efficiency and low installation efficiency. At the same time, after installation, the discharge needle is sleeved inside the ceramic and is not easy to rotate. In the case of long-term use, the discharge needle is prone to rust due to diffusion, and it is difficult to take out for maintenance and repair in the later stage, affecting the practicability of the device. Therefore, it is very necessary to design an ignition device for an electric gas stove. Content of the Utility Model
