Description

Technical Field

[0001] This utility model relates to the field of igniter technology, specifically to an igniter assembly structure. Background Technology

[0002] A high-voltage igniter is an ignition device widely used in gas stoves, gas water heaters, industrial combustion equipment, and other fields. Its basic working principle is to generate a voltage of several thousand volts through a high-voltage circuit, which breaks down the air at the gap between the ignition electrodes, generating an electric spark to ignite the combustible gas.

[0003] Currently, most commercially available igniters employ an open structure, meaning the ignition electrodes are directly exposed to the installation environment. During combustion, combustion products such as carbon black gradually deposit on the surface of the electrodes and their insulating ceramic bodies. These contaminants reduce the insulation performance between the electrodes, leading to high-voltage leakage, weakened spark energy, or even the inability to generate a spark, resulting in ignition failure or low ignition efficiency. Furthermore, the exposed electrodes are constantly exposed to high temperatures, high humidity, and even corrosive environments, which accelerates their aging and corrosion, further affecting their performance and lifespan. Therefore, this paper proposes an igniter component structure. Utility Model Content

[0004] The purpose of this invention is to provide an igniter assembly structure to solve one of the problems mentioned in the background art.

[0005] This utility model is implemented by the following technical solution: an igniter assembly structure, including a protective assembly, wherein the protective assembly includes a housing, a wire, a through hole, a guide rod, a spring, a baffle and a mounting groove; A wire is installed at the bottom of the housing, and through holes are symmetrically opened at the top of the housing. A guide rod is fixedly connected to the inner wall of the through hole, and a spring is sleeved on the outer wall of the guide rod. A baffle is fixedly connected to one end of the guide rod, and the baffle is set at the top of the housing. An installation groove is opened on the upper surface of the housing. In the unignited state, the baffle is pulled to cover the installation groove under the elastic force of the spring. When the igniter is working, the electromagnet is energized and generates magnetic force, which repels the like poles of the magnet, causing the slide to slide upward along the inner wall of the installation groove. At the same time, the slide drives the push rod to move upward synchronously. The top of the push rod pushes the baffle, causing the baffle to move upward against the elastic force of the spring. The limiting blocks symmetrically fixedly connected to the inner wall of the installation groove limit the movement of the slide, preventing the slide from falling out of the installation groove and ensuring the precise extension length of the high voltage electrode and the ground electrode. Ignition is performed after the high voltage electrode and the ground electrode extend out of the installation groove.

[0006] As a further preferred embodiment of this technical solution: the protective component is provided with an ignition component inside, the ignition component including a slide and a magnet; A slide block is slidably connected to the inner wall of the mounting groove, and a magnet is fixedly connected to the bottom of the slide block.

[0007] As a further preferred embodiment of this technical solution: an electromagnet is installed at the bottom of the mounting groove, and the electromagnet is positioned below the magnet.

[0008] As a further preferred embodiment of this technical solution, the top of the slide is symmetrically and fixedly connected with two mounting seats.

[0009] As a further preferred embodiment of this technical solution: a high-voltage electrode and a grounding electrode are respectively installed inside the two mounting bases.

[0010] As a further preferred embodiment of this technical solution: the inner sidewall of the mounting groove is symmetrically and fixedly connected with limiting blocks, and the limiting blocks are disposed above the slide.

[0011] As a further preferred embodiment of this technical solution: the top of the slide block is symmetrically and fixedly connected with top rods.

[0012] As a further preferred embodiment of this technical solution: one end of the top rod is disposed at the bottom of the baffle.

[0013] Advantages of this utility model: 1. This utility model uses the elastic force of a spring to pull the baffle to cover the mounting groove, forming a physical barrier to isolate the influence of external carbon black, moisture and corrosive gases on the high voltage electrode and the grounding electrode. 2. This utility model uses an electromagnet to generate magnetic force, which causes the magnet to drive the slide block to slide up along the mounting groove. The push rod simultaneously pushes up the baffle, and the electrode extends out to work. The maximum stroke of the slide block is limited by the limiting block, and the extension length of the electrode is precisely controlled. 3. This utility model utilizes the switching on and off of the electromagnet to achieve rapid response, ensuring that the electrode is only exposed during ignition, shortening the exposure time in high-temperature environments, and delaying electrode aging.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example Please see Figures 1-4 This utility model provides a technical solution: an igniter assembly structure, including a protective assembly 10, the protective assembly 10 including a housing 11, a wire 12, a through hole 13, a guide rod 14, a spring 15, a baffle 16 and a mounting groove 17; A wire 12 is installed at the bottom of the housing 11. Symmetrical through holes 13 are provided at the top of the housing 11. A guide rod 14 is fixedly connected to the inner wall of the through hole 13. A spring 15 is sleeved on the outer wall of the guide rod 14. A baffle 16 is fixedly connected to one end of the guide rod 14. The baffle 16 is located at the top of the housing 11. A mounting groove 17 is provided on the upper surface of the housing 11. In the unignited state, the baffle 16 is pulled to cover the mounting groove 17 by the elastic force of the spring 15. When the igniter is working, the electromagnet 23 is energized to generate magnetic force, which is the same as that of the magnet 22. The poles repel each other, causing the slide 21 to slide upward along the inner wall of the mounting groove 17. At the same time, the slide 21 drives the push rod 28 to move upward synchronously. The top of the push rod 28 pushes the baffle 16, causing the baffle 16 to move upward against the elastic force of the spring 15. The limiting blocks 27 symmetrically and fixedly connected to the inner side wall of the mounting groove 17 limit the movement of the slide 21, preventing the slide 21 from leaving the mounting groove 17 and ensuring that the extension length of the high voltage electrode 25 and the ground electrode 26 is accurate. After the high voltage electrode 25 and the ground electrode 26 extend out of the mounting groove 17, the ignition work is carried out.

[0019] In this embodiment, specifically: the protective component 10 is provided with an ignition component 20, which includes a slide 21 and a magnet 22; A slide block 21 is slidably connected to the inner wall of the mounting groove 17. A magnet 22 is fixedly connected to the bottom of the slide block 21. The movement direction of the slide block 21 is controlled by the cooperation of the electromagnet 23 and the magnet 22.

[0020] In this embodiment, specifically: an electromagnet 23 is installed at the bottom of the mounting slot 17. The electromagnet 23 is located below the magnet 22. When not ignited, the opposite magnetic poles of the electromagnet 23 and the magnet 22 are opposite to each other, attracting the slide block 21 to prevent the electrode from moving. When ignited, the magnetic poles of the electromagnet 23 change, pushing the slide block 21 to move upward.

[0021] In this embodiment, specifically: two mounting seats 24 are symmetrically fixedly connected to the top of the slide 21, and the mounting seats 24 are made of insulating material.

[0022] In this embodiment, specifically: a high-voltage electrode 25 and a grounding electrode 26 are respectively installed inside the two mounting bases 24. When the system initiates the ignition procedure, the power supply applies a high voltage to the high-voltage electrode 25. Under the action of the high voltage, the air around the high-voltage electrode 25 is ionized, and the air in the conductive channel is rapidly heated, causing the temperature to rise sharply. When the temperature rises to a certain level, reaching the ignition point of the combustible material, the combustible material will be ignited, thereby achieving the purpose of ignition. The grounding electrode 26 plays an important role in providing a circuit for the current throughout the process, ensuring that the current can flow continuously and stably, and guaranteeing the smooth progress of the ignition process.

[0023] In this embodiment, specifically: the inner sidewall of the mounting groove 17 is symmetrically and fixedly connected with a limiting block 27. The limiting block 27 is located above the slide 21. The limiting block 27 limits the movement of the slide 21, preventing the slide 21 from leaving the mounting groove 17 and ensuring that the extension length of the high voltage electrode 25 and the grounding electrode 26 is accurate.

[0024] In this embodiment, specifically: a top rod 28 is symmetrically fixedly connected to the top of the slide 21, and the top end of the top rod 28 is higher than the top end of the electrode to avoid the electrode from contacting or getting too close to the baffle 16.

[0025] In this embodiment, specifically: one end of the push rod 28 is disposed at the bottom of the baffle 16, and the push rod 28 is used to push the baffle 16 so that the baffle 16 moves upward against the elastic force of the spring 15 so that the electrode can extend.

[0026] Working principle or structural principle: In use, when not ignited, the spring force of spring 15 pulls the baffle 16 to cover the mounting groove 17, forming a physical barrier to isolate the influence of external carbon black, moisture, and corrosive gases on the high-voltage electrode 25 and the grounding electrode 26. When the igniter is working, the electromagnet 23 is energized and generates magnetic force, which repels the same magnetic pole of the magnet 22, causing the slide 21 to slide upward along the inner wall of the mounting groove 17. At the same time, the slide 21 drives the push rod 28 to move upward synchronously. The top of the push rod 28 pushes the baffle 16, causing the baffle 16 to move upward against the spring force of spring 15. The limiting blocks 27 symmetrically fixed to the inner wall of the mounting groove 17 limit the movement of the slide 21, preventing the slide 21 from leaving the mounting groove 17 and ensuring the precise extension length of the high-voltage electrode 25 and the grounding electrode 26. After the high-voltage electrode 25 and the grounding electrode 26 extend out of the mounting groove 17, ignition is performed. After ignition is completed, the electromagnet 23 is de-energized, the magnetic force disappears, the spring 15 pulls the baffle 16 to reset, and at the same time the baffle 16 drives the two push rods 28 to move down. The push rods 28 push the slide 21 to reset, the high voltage electrode 25 and the ground electrode 26 retract into the mounting groove 17, and the baffle 16 covers the mounting groove 17 again to protect the high voltage electrode 25 and the ground electrode 26.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
