[0027] Please refer to Figures 1 to 4 The utility model provides a ceramic fire cover ignition electrode, comprising:

[0028] Burner body 1;

[0029] A ceramic fire cover 2 is abutted against the burner body 1;

[0030] High-pressure ignition needle 4, which is connected to the burner body 1;

[0031] The ignition electrode 3 is embedded in the ceramic fire cover 2 and exposed outside the ceramic fire cover 2 . The ignition electrode 3 is arranged in contact with the burner body 1 and is arranged opposite to the high-voltage ignition needle 4 .

[0032] In this embodiment, the ceramic fire cover ignition electrode includes a burner body 1, on which a ceramic fire cover 2 is placed. The fire cover made of ceramic material can remain unchanged at high temperatures and can save natural resources, but the ceramic fire cover is not conductive. Therefore, an ignition electrode 3 is embedded in the ceramic fire cover 2, and the ignition electrode 3 is arranged in contact with the burner body 1, thereby realizing a grounding circuit between the ignition electrode 3 and the burner body 1.

[0033] Among them, a high-voltage ignition needle 4 is also connected to the burner body 1. When high-voltage electricity is used for ignition, the high-voltage ignition needle 4 can be used to discharge and ignite the ignition electrode 3 on the burner body 1. Specifically, the high-voltage ignition needle 4 is fixedly connected to the burner body 1 by screws, and the tip close to the ignition electrode 3 is arranged opposite to the ignition electrode 3, so that the high-voltage electricity released by the high-voltage ignition needle 4 can generate an arc with the ignition electrode 3, thereby igniting. In summary, the ceramic fire cover in the embodiment of the present application has the advantages of simple structure, low cost, and easy implementation.

[0034] Furthermore, the burner body 1 is made of metal material, specifically aluminum alloy, etc. The burner body 1 can be manufactured by cold rolling or hot die casting.

[0035] Furthermore, the ignition electrode 3 is made of a conductive material. The ignition electrode 3 is made of a conductive metal material or a conductive non-metallic material, specifically copper, so that when it contacts the metal burner body 1, it can achieve conduction with the burner body 1 and realize a grounding loop.

[0036] Furthermore, a plurality of fire holes 21 are evenly distributed along the circumference of the ceramic fire cover 2 close to the burner body 1 , the ignition electrode 3 is embedded in the ceramic fire cover 2 through the fire hole 21 and exposed on the ceramic fire cover 2 , and the high-voltage ignition needle 4 is arranged opposite to the ignition electrode 3 through the fire hole 21 .

[0037] In this embodiment, the ceramic fire cover 2 is specifically in the shape of a circular ring, and a plurality of fire holes 21 are evenly distributed on the outer circumference of the ceramic fire cover 2 on one side close to the burner body 1. The ignition electrode 3 is embedded in the ceramic fire cover 2 through the plurality of fire holes 21. Specifically, the ignition electrode 3 is embedded in the plurality of fire holes 21, and the ignition electrode 3 is exposed outside the ceramic fire cover 2 through the fire holes 21, so that the ignition electrode 3 can better generate an arc with the high-voltage ignition needle 4. Specifically, the high-voltage ignition needle 4 is arranged relative to the ignition electrode 3 through the fire hole 21, so that the high-voltage ignition needle 4 can generate an arc with the ignition electrode 3, thereby igniting the combustible gas flowing out of the fire hole 21.

[0038] The fire hole 21 is tooth-shaped or circular. The shape of the fire hole 21 is not limited here and is set according to actual production requirements.

[0039] Furthermore, the ignition electrode 3 includes an electrode discharge end 31, and the two ends of the electrode discharge end 31 are respectively connected to an electrode conductive end 32. The electrode discharge end 31 is exposed to the ceramic fire cover 2 through the fire hole 21 and is arranged opposite to the high-voltage ignition needle 4. The two electrode conductive ends 32 are arranged in contact with the burner body 1.

[0040] In this embodiment, the ignition electrode 3 includes an electrode discharge end 31, which is exposed outside the ceramic fire cover 2 through the fire hole 21 and is arranged opposite to the high-voltage ignition needle 4, wherein an electrode conductive end 32 is respectively provided at both ends of the electrode discharge end 31, and the two electrode conductive ends 32 are respectively provided in contact with the burner body 1, and the high-voltage ignition needle 4 is also connected to the burner body 1 to realize a grounding loop, and then high voltage electricity is discharged through the high-voltage ignition needle 4, and the electrode conductive end 32 conducts the current to the electrode discharge end 31, and the electrode discharge end 31 then collides the current with the high voltage electricity discharged by the high-voltage ignition needle 4 to generate an arc, and then the combustible gas flowing out of the fire hole 21 is ignited by the generated arc, and a flame is generated.

[0041] Furthermore, the ignition electrode 3 has a "concave" structure. Setting the ignition electrode 3 into a "concave" structure allows the ignition electrode 3 to be more firmly embedded in the fire hole 21 of the ceramic fire cover 2 and is not easy to fall off.

[0042] Furthermore, a gas nozzle 5 is connected to one end of the burner body 1 , and the gas nozzle 5 is communicated with the fire hole 21 .

[0043] In this embodiment, a gas nozzle 5 is connected to one end of the burner body 1, through which gas can be injected into the burner body 1. The gas injected into the burner body 1 from the gas nozzle 5 flows directly into the flame holes 21 on the ceramic fire cover 2, thereby allowing the arc generated by the high-voltage ignition needle 4 and the ignition electrode 31 to ignite the combustible gas flowing out of the flame holes 21. The interior of the burner body 1 has a hollow structure, so that the combustible gas from the gas nozzle 5 flows directly into the multiple flame holes 21.

[0044] Furthermore, the specific implementation steps of the ceramic fire cover ignition electrode in the embodiment of the present application are:

[0045] The gas is injected into the burner body 1 from the gas nozzle 5, and the gas flows directly from the burner body 1 to the fire hole 21 on the ceramic fire cover 2, and then discharges high voltage electricity through the high-voltage ignition needle 4. The electrode conductive end 32 conducts the current to the electrode discharge end 31, and the electrode discharge end 31 then collides the current with the high voltage electricity discharged by the high-voltage ignition needle 4 to generate an arc, and then the combustible gas flowing out of the fire hole 21 is ignited by the generated arc, and a flame is generated.

[0046] The present invention provides a ceramic fire cover ignition electrode, comprising: a burner body; a ceramic fire cover, the ceramic fire cover abutting against the burner body; a high-voltage ignition needle, the high-voltage ignition needle connected to the burner body; an ignition electrode, the ignition electrode embedded in the ceramic fire cover and exposed from the ceramic fire cover, the ignition electrode being arranged in contact with the burner body and arranged opposite to the high-voltage ignition needle. Through the ceramic fire cover ignition electrode provided by the present invention, the ignition electrode embedded in the ceramic fire cover is connected to the burner body to realize a grounding circuit. When gas is injected into the burner body from the gas nozzle and flows out from the fire hole of the ceramic fire cover, an arc can be generated between the high-voltage ignition needle and the ignition electrode and ignition can be performed, which has the advantages of simple structure, low cost and easy implementation.
