Description

Technical Field

[0001] This utility model relates to the field of ignition equipment technology, and in particular to a coil frame for an igniter. Background Technology

[0002] An igniter is a device that provides enough energy in an instant to ignite pulverized coal or oil (gas) fuel and stabilize the flame. Ignitioners are divided into commercial and residential stoves: commercial ignitioners are mainly used in restaurant kitchens because the environment is more complex, thus requiring stricter specifications for ignitioners compared to residential stoves. Residential ignitioners are mainly used in household stoves, where the environment is simpler than in restaurants, and pulse ignition is generally more common.

[0003] The invention application patent with announcement number CN108831710A discloses a high-voltage transformer for an arc igniter, which includes a frame body, a first winding, a second winding, and a magnetic core mounted on the frame body. The first winding and the second winding are isolated and positioned by a plastic retaining ring. Each end of the frame body is provided with a first winding post and a second winding post for fixing the winding of the first winding. Multiple winding grooves are formed on the frame body by partitions. A wire-passing cut groove is provided between two adjacent winding grooves for passing wires and reducing voltage difference. The winding of the first winding is wound in the winding groove, and the winding of the second winding is wound on the plastic retaining ring.

[0004] In the above structure, the first winding is wound inside the winding slot, and the second winding is wound around a plastic retaining ring. Both the first winding and the high-voltage wire are wound and positioned with two winding posts, and the high-voltage wire is welded to the winding posts. The second winding is directly led out as a fly wire and connected to the circuit board of the arc ignition gun. Therefore, existing high-voltage transformers require manual assembly and welding, making fully automated production impossible, resulting in low processing efficiency and inconsistent product quality. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art by providing a coil frame for an igniter with four winding posts. The second winding is also wound around the winding posts instead of being led out by a flying wire, which facilitates subsequent automated assembly.

[0006] The technical solution of this utility model is as follows: a coil frame for an igniter, comprising a frame body, wherein the frame body is provided with several partitions, and a winding groove is formed between two adjacent partitions. A through hole is provided through the middle of the frame body, and a magnetic core is inserted into the through hole. The frame body is also provided with a first set of winding posts connected to a first winding and a second set of winding posts connected to a second winding. Each set of winding posts is provided with two of them, and each winding post is arranged perpendicular or parallel to the axis of the through hole.

[0007] By adopting the above technical solution, two sets of winding posts are set up. The first winding group can be wound and fixed on the first winding post, and the second winding group can be wound and fixed on the second winding post. This solves the problem in the prior art where the second winding group is directly led out by a flying wire, which makes subsequent automated processing impossible. In addition, the first winding group and the second winding group can be fixed and led out independently, with clearer electrical isolation, avoiding winding crossover and confusion, and improving connection reliability and stability.

[0008] A further feature of this invention is that a first mounting base and a second mounting base are fixedly connected or integrally formed on the partition plate at the end of the skeleton body. The first mounting base is provided with a first mounting channel, and a first set of winding posts are inserted into the first mounting channel. The second mounting base is provided with a second mounting channel, and a second winding post is inserted into the mounting channel of the second mounting base.

[0009] The above-mentioned further design facilitates the installation and fixation of the winding post, making its structure robust and facilitating the subsequent winding of the winding assembly. Furthermore, a lead wire groove can be provided on the mounting base to facilitate the winding of the wire into and out of the winding groove.

[0010] A further feature of this invention is that a first mounting seat is integrally formed on a partition plate at one end of the frame body, and a second mounting seat is integrally formed on a partition plate at the other end of the frame body. The first mounting seat and the second mounting seat are located on the outer end faces of the corresponding partition plates. The first mounting seat is provided with the first mounting channel, and the second mounting seat is provided with the second mounting channel.

[0011] A further feature of this invention is as follows: two first mounting seats are integrally formed on the partition plate at one end of the frame body, and each of the two first mounting seats is provided with the first mounting channel; two second mounting seats are integrally formed on the partition plate at the other end of the frame body, and each of the two second mounting seats is provided with the second mounting channel; the first mounting seats and the second mounting seats are respectively located on the outer end face of the corresponding partition plate; the two first mounting seats and the two second mounting seats are respectively located on both sides of the through hole.

[0012] By adopting the above-mentioned further configuration, the mounting bases are respectively located at both ends of the frame body, which makes the frame more stable and ensures that the winding groups do not interfere with each other when they are wound, making it easier to wind and fix the winding groups without tangling.

[0013] A further improvement of this invention is as follows: the skeleton body is horizontally oriented, the through holes are arranged along the horizontal direction of the skeleton body, and the first set of winding posts and the second set of winding posts are respectively located at both ends of the skeleton body and arranged along the vertical direction of the skeleton body.

[0014] With the above-mentioned further design, the excellent natural heat dissipation performance and the vertical diffusion of heat help to balance gravity, reduce lateral forces, and lower the risk of overall tilting.

[0015] A further improvement of this invention is as follows: the skeleton body is vertically oriented, the through holes are arranged along the vertical direction of the skeleton body, and the first set of winding posts and the second set of winding posts are respectively located at both ends of the skeleton body and arranged along the horizontal direction of the skeleton body.

[0016] With the above-mentioned further configuration, the four winding posts are located on the same vertical plane, the lead direction is more natural, the multi-winding coils can be led out more easily and independently, the reduction of wire harness crossing makes it easier to arrange heat dissipation channels, the heat can be distributed more evenly in the horizontal direction, and the risk of local overheating is reduced.

[0026] like Figure 1-4 As shown, a coil frame for an igniter includes a frame body 1. The frame body 1 has several partitions 11, with a winding groove 12 formed between adjacent partitions 11. A through hole 13 is provided through the middle of the frame body 1, and a magnetic core is inserted into the through hole 13. The frame body 1 also has a first set of winding posts 14 connected to a first winding and a second set of winding posts 15 connected to a second winding. Each set of winding posts has two posts, and each winding post is perpendicular or parallel to the axis of the through hole 13. The two sets of winding posts can face the same direction or opposite directions. With two sets of winding posts, the first winding group can be wound and fixed on the first winding post, and the second winding group can be wound and fixed on the second winding post. This solves the problem in the prior art where the second winding group is directly led out by a flying wire, which makes subsequent automated processing impossible. The high-voltage wire can be welded later, and the first winding group and the second winding group can be fixed and led out independently, resulting in clearer electrical isolation, avoiding winding crossover and confusion, and improving connection reliability and stability.

[0027] A first mounting base 16 and a second mounting base 17 are fixedly connected to or integrally formed on the partition plate 11 at the end of the skeleton body 1. The first mounting base 16 and the second mounting base 17 can be set on the same end face or on different end faces. When set on the same end face, the two sets of winding posts are set in different directions, preferably in opposite directions. When set on two end faces, the two sets of winding posts can be set in the same direction or in different directions. The first mounting base 16 is provided with a first mounting channel 161, and the first set of winding posts 14 are inserted into the first mounting channel 161. The second mounting base 17 is provided with a second mounting channel 171, and the second winding post is inserted into the mounting channel of the second mounting base 17. This facilitates the installation and fixation of the winding posts, making the structure firm and facilitating the winding of the subsequent winding group. A lead wire groove can be provided on the mounting base to facilitate the winding of wires into and out of the winding groove 12.

[0028] A first mounting base 16 is integrally formed on a partition 11 at one end of the frame body 1, and a second mounting base 17 is integrally formed on a partition 11 at the other end of the frame body 1. The first mounting base 16 and the second mounting base 17 are located on the outer end faces of the corresponding partitions 11. The first mounting base 16 is provided with the first mounting channel 161, and the second mounting base 17 is provided with the second mounting channel 171. One first mounting base 16 and two second mounting bases 17 can be provided. If only one is provided, each mounting base is provided with two mounting channels. The frame body 1 is horizontally arranged, and the through hole 13 is arranged along the horizontal direction of the frame body. The first set of winding posts 14 and the second set of winding posts 15 are respectively located at both ends of the frame body and are arranged along the vertical direction of the frame body. This has good natural heat dissipation performance, and heat is diffused in the vertical direction. It also helps to balance gravity, reduce lateral forces, and reduce the risk of overall tilting.

[0029] Two first mounting seats 16 are integrally formed on the partition plate 11 at one end of the frame body 1. Each of the two first mounting seats 16 is provided with a first mounting channel 161. Two second mounting seats 17 are integrally formed on the partition plate 11 at the other end of the frame body 1. Each of the two second mounting seats 17 is provided with a second mounting channel 171. The first mounting seats 16 and the two mounting seats 17 are respectively located on the outer end face of the corresponding partition plate 11. The two first mounting seats 16 and the two second mounting seats 17 are respectively located on both sides of the through hole 13. By setting the mounting seats at both ends of the frame body 1, the frame is stabilized. The structure is good, and the winding groups do not interfere with each other when they are wound, which makes it easy to wind and fix the winding groups without tangling; the skeleton body 1 is set vertically, the through hole 13 is set along the vertical direction of the skeleton body 1, the first group of winding posts 14 and the second group of winding posts 15 are respectively set at both ends of the skeleton body 1 and set along the horizontal direction of the skeleton body 1. The four winding posts are located on the same vertical plane, the lead wire direction is more natural, the multi-winding coils can be led out more easily and independently, the wire bundle crossing is reduced, the heat dissipation channel is easier to arrange, the heat can be distributed more evenly along the horizontal direction, and the risk of local overheating is reduced.
