Example Embodiment
[0021] Specific implementation manner two: combination figure 1 To illustrate this embodiment, each telescopic component described in this embodiment includes a spring connector 5, a spring 6 and a connecting assembly 7. One end of the spring 6 is connected to a corresponding electrode assembly 1 through the spring connector 5; the other of the spring 6 One end is connected to a corresponding intermediate contact 8 through the connection kit 7.
[0022] With this arrangement, the telescopic component can enable the electrode to have a telescopic function with the movement of the burner damper switch, which is convenient for ignition.
[0023] The other components and connection relationships are the same as in the first embodiment.
Example Embodiment
[0024] Specific implementation mode three: combination figure 1 To illustrate this embodiment, each electrode assembly 1 described in this embodiment includes an electrode 1-1 and an insulating ceramic sheath 1-2. The insulating ceramic sheath 1-2 is sleeved on the electrode 1-1, and the ignition of the electrode 1-1 The end extends from the end of the insulating ceramic sheath 1-2.
[0025] In this way, an insulating ceramic sheath 1-2 is added to each electrode to strengthen insulation and enhance oxidation resistance.
[0026] The other components are the same as in the second embodiment in terms of connection relationship.
Example Embodiment
[0027] Specific implementation manner 4: Combination figure 1 To explain this embodiment, the ignition device for improving the life of an oil-fired boiler described in this embodiment further includes a fixed pressing plate 2 which is sleeved in the middle of the two insulating ceramic sheaths 1-2.
[0028] The pressing plate 2 is composed of upper and lower halves of stainless steel pressing plates. The upper pressing plate and the lower pressing plate are arranged opposite to each other. They are used to fix the insulating ceramic sheaths on the outside of the two electrode assemblies, and at the same time serve as a limiter and are also used for connecting with the burner damper. The snap connection on the baffle.
[0029] Other components and connection relationships are the same as those in the first, second or third embodiment.
