Description

Technical Field

[0001] This utility model belongs to the field of ignition core technology, and specifically relates to a semiconductor ignition core. Background Technology

[0002] The hot surface igniter with a flat plate structure is used in sealed gas ovens, gas dryers, and boiler equipment. It is resistant to oxidation at high temperatures and has high efficiency and safety performance when connected in series with a bimetallic gas valve. At the same time, it solves the problem of deflagration and explosion caused by the large amount of gas emitted after ignition due to poor ignition of ordinary igniters. Its process is to obtain a high-density, low-resistivity product through reaction sintering and recrystallization.

[0003] In existing technologies, ignition cores mostly adopt a flat plate structure. When these flat plate ignition cores are used in gas appliances, their flat plate structure will block the flow of gas, resulting in poor gas flow and insufficient contact between the gas and the heating surface of the ignition core, thereby reducing the ignition probability and affecting the performance.

[0004] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0005] To solve the above technical problems, the present invention provides a semiconductor ignition core, including an ignition core body. The ignition core body is flat and divided into an annular segment and a straight segment. The annular segment has an annular groove, and the straight segment has a through groove in the middle. The through groove is connected to the annular groove, and a transition curved surface is provided at the connection between the through groove and the annular groove so that the annular groove is teardrop-shaped. A connecting segment is symmetrically arranged between the annular segment and the straight segment. The connecting segment is divided into a first curved surface and a second curved surface. The first curved surface is connected to the second curved surface. The end of the first curved surface is connected to the annular segment, and the end of the second curved surface is connected to the straight segment. The curvature of the first curved surface is greater than the curvature of the second curved surface. Slots are symmetrically provided at the ends of the straight segments for inserting conductive wires.

[0006] The ignition core body is 2 mm thick, the annular section is 12 mm in diameter, the annular groove formed by the annular section is 8 mm in diameter, the straight section is 12 mm wide, the through groove is 1 mm wide, the transition surface has a radius of 5 mm, the first surface has a radius of 1.5 mm, the second surface has a radius of 8.88 mm, the two slots are 6 mm apart, the slot is 5 mm long, the slot is 1 mm wide, and the end of the straight section is 30 mm from the center of the annular groove.

[0007] The ignition core body is made using a one-piece molding process.

[0008] The ignition core is made of silicon carbide.

[0009] This utility model has the following beneficial effects: This invention forms a connected gas passage structure by using the annular groove of the annular segment and the through groove of the straight segment. This structure can guide the gas to flow smoothly along the annular groove and through groove, avoiding obstruction by the ignition core body. Combined with the excellent thermal conductivity of silicon carbide semiconductor material, the gas can fully surround the heating surface of the ignition core body, achieving uniform heating and effectively improving the ignition probability. Meanwhile, the annular groove structure of the ring section can quickly fit the chick's beak, and the annular groove fits the beak well. The ignition core heats up evenly, which can more practically complete the scalding operation of the beak, avoid damage to the tissue around the beak, and meet the needs of both gas ignition and scalding chicken beaks in breeding scenarios, making it highly practical.

[0010] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
