Description

Technical Field

[0001] The utility model relates to the technical field of ignition equipment, in particular to a multi-head ceramic ignition needle. Background Art

[0002] Ceramic ignition needles utilize the high electrical conductivity of ceramic materials to generate an arc under high voltage to ignite the mixed gas. Ceramic ignition needles are widely used, mainly in industries such as industry, automobiles, and household appliances.

[0003] In the industrial field, ceramic ignition needles can be used to ignite burners, industrial furnaces and other equipment; in the automotive field, they can be used to ignite ignition systems such as spark plugs; in the field of household appliances, they can be used to ignite household appliances such as gas stoves and water heaters. The working principle of ceramic ignition needles is that when a high-pressure mixed gas passes through the ceramic ignition needle, due to the high conductivity of the ceramic, an arc is generated under high pressure, thereby igniting the mixed gas;

[0004] From the above content, it is known that ceramic ignition needles still have shortcomings during actual operation: when operating existing ceramic ignition needles, personnel need to install and fix them with parts first. If they need to be repaired or replaced, the parts on the ceramic ignition needles need to be disassembled again. When the installation space of the ceramic ignition needles is relatively limited, it will cause more inconveniences for personnel during disassembly and assembly; and the current ceramic ignition needles generally adopt single-head ignition operation. If faced with different combustion points or combustion surfaces, the single-head ceramic ignition needles will cause uneven combustion in the combustion chamber;

[0005] Therefore, the present application proposes a multi-head ceramic ignition needle. Utility Model Content

The electrode core 64 is docked and installed between the ignition terminal 62 and the power terminal 65.

[0043] During this period, the power terminal 65 completes the electrical connection of the ignition needle through the upper and lower contacts. After power is connected, the power terminal 65 ignites the ignition terminal 62 through the electrode core 64, prompting the ignition head 63 on the ignition terminal 62 to complete the external ignition operation, and during the operation, the internal electrical contacts are protected by the inner porcelain sleeve 61.

[0044] In this embodiment, the isolation component 7 includes an isolation plate 71 and a top cover 72.
