Embodiment 1
[0028] Embodiment 1: see attached figure 1 to attach Figure 5 , the pulse discharge ignition and flameout protection device for infrared cookers described in this embodiment is installed at the gas outlet on the inner side wall of the central ventilation channel 3 of the furnace cavity 1, and the device includes a high temperature resistant insulating sleeve 4 , conductive needle 5, conductive connecting body 6, and electrode piece 7, wherein, the high temperature resistant insulating sleeve 4 is installed in the central ventilation channel 3, the conductive pin 5 is located in the high temperature resistant insulating sleeve 4, and the high temperature resistant insulating sleeve 4 is made of ceramic and non-conductive Made of insulating material, and fixed in the central ventilation channel 3 by means of screws or mechanical connections. The lower end of the conductive needle 5 passes through the high-temperature-resistant insulating sleeve 4 and is connected with the elec...
Embodiment 2
[0030] Embodiment 2: see attached Figure 6 , attached Figure 7 The difference between this embodiment and Embodiment 1 is that the upper end of the conductive needle 5 below the airflow blocking area 8 has a bent portion 2 extending laterally. The bending part 2 has a conductive function, which can make the gas in the recirculation area easier to ignite. And the airflow slot 11 of this embodiment is a circular hole or an oval hole.
