Description

Therefore, when the grounding conduction ability of the ignition needle is insufficient during the pulse discharge process, leakage or intermittent discharge will occur. Therefore, in order to increase the ignition performance of the burner, some products embed a metal ring on the ceramic body of the ignition needle to make it have good grounding conduction ability, but this solution is relatively costly, and the process of embedding the metal ring is relatively complicated.

The inner shielding member 21 is arranged on the outer wall of the inner ring 11 of the ignition divider, and the outer shielding member 22 is arranged on the inner wall of the outer ring 12 of the ignition divider. The inner shielding member 21 and the outer shielding member 22 are arranged opposite to each other and form a shielding cavity 20.

The shielding member 2 is located between the inner ring 11 and the outer ring 12 of the igniter, and the inner fire cover 500 of the burner is buckled on the inner ring 11 of the igniter, and the outer fire cover 600 of the burner is buckled on the outer ring 12 of the igniter. The tip of the ignition needle 300 will be located above the inner fire cover 500 and the outer fire cover 600 when it extends out of the shielding cavity 20, that is, the shielding member 2 not only helps to enhance the grounding conduction capability of the ignition needle 300, but also when the ignition needle 300 has leakage or intermittent ignition, the ignition needle 300 always discharges at the tip, that is, discharges above the inner fire cover 500 and the outer fire cover 600. In addition, the shielding member 2 provided in this embodiment includes an inner shielding member 21 and an outer shielding member 22 which are arranged relatively to each other, and the two are respectively arranged on the inner ring 11 and the outer ring 12 of the ignition divider, which is easy to install.

[0043] like Figure 2 As shown, the inner shielding member 21 has a first curved surface 211, and the outer shielding member 22 has a second curved surface 221. The first curved surface 211 and the second curved surface 221 are arranged to form a shielding cavity 20. In this embodiment, the first curved surface 211 and the second curved surface 221 are fitted to obtain the same fitting circle, and the center of the fitting circle coincides with the central axis of the ignition needle 300. The ignition needle 300 is a cylindrical structure, and the shielding cavity 20 is a cylindrical cavity. The ignition needle 300 is inserted into the shielding cavity 20, and the distance between the outer circumference of the ignition needle 300 and the shielding cavity 20 is consistent.

[0044] Optionally, the center angle of the first curved surface 211 is a1, the center angle of the second curved surface 221 is a2, and 120°≤a1+a2≤360°. In a specific implementation, when the inner shielding member 21 and the outer shielding member 22 are relatively arranged to form the shielding cavity 20, the inner shielding member 21 and the outer shielding member 22 can be arranged at intervals or in abutment with each other. The first curved surface 211 of the inner shielding member 21 and the second curved surface 221 of the outer shielding member 22 are respectively recessed in opposite directions along the radial direction of the ignition needle 300 to form the shielding cavity 20.

In this embodiment, because the shielding cavity 20 is a cylindrical cavity coaxially arranged with the ignition needle 300, the distance between the first curved surface 211 of the inner shielding member 21 and the outer peripheral surface of the ignition needle 300 is consistent, and the distance between the second curved surface 221 of the outer shielding member 22 and the outer peripheral surface of the ignition needle 300 is consistent.

When the ignition divider 100 is installed on the nozzle base 200, the ignition needle 300 is penetrated into the shielding cavity 20, and the tip of the ignition needle 300 extends out of the shielding cavity 20. Because the shielding member 2 of the ignition divider 100 is located between the inner ring 11 and the outer ring 12 of the ignition divider, and the inner fire cover 500 of the burner is buckled on the inner ring 11 of the ignition divider, and the outer fire cover 600 of the burner is buckled on the outer ring 12 of the ignition divider, the tip of the ignition needle 300 will be located above the inner fire cover 500 and the outer fire cover 600 when it extends out of the shielding cavity 20, that is, the shielding member 2 not only helps to enhance the grounding conduction capability of the ignition needle 300, but also when the ignition needle 300 leaks electricity or intermittent ignition occurs, the ignition needle 300 always discharges at the tip, that is, discharges above the inner fire cover 500 and the outer fire cover 600. In addition, the inner shielding member 21 and the outer shielding member 22 are respectively arranged on the inner ring 11 and the outer ring 12 of the ignition divider, which are easy to install. Compared with the prior art of setting a metal ring on the ceramic body of the ignition needle 300 through a nesting process, the process complexity is greatly reduced, which can save production costs.

[0052] This embodiment also provides a stove, including the above-mentioned burner. The burner of the stove is provided with a shielding member 2 on the ignition distributor body 1, and the ignition needle 300 of the burner is inserted into the shielding cavity 20 of the shielding member 2, which helps to enhance the grounding conduction ability of the ignition needle 300.

In addition, the inner shielding member 21 and the outer shielding member 22 are respectively provided on the inner ring 11 and the outer ring 12 of the ignition distributor.
