Abstract
Description
An electrode mounting structure and an umbrella-shaped ignition needle Technical Field
[0001] This utility model relates to the field of ignition needle technology, specifically to an electrode plate mounting structure and an umbrella-shaped ignition needle. Background Technology
[0002] The stove consists of a burner and an ignition needle mounted on it. The ignition needle is connected to a high-voltage igniter via a wire, and its head is fixed to the burner. The electrode plate ignites the gas by ionizing ions in the gas using high-voltage electricity. During ignition, the electrode plate generates a high-voltage spark, creating an ion channel in the gas, causing a discharge reaction that ignites the fuel. Currently, the bottom of the ignition needle typically has a cylindrical groove, and the electrode plate is fixed in the groove with high-temperature resistant adhesive. However, under long-term high-temperature conditions, the adhesive and electrode plate are prone to aging and detachment, resulting in low reliability and a lack of mechanical structure to enhance stability. Summary of the Invention
[0003] To address at least one of the aforementioned problems, this utility model first provides an electrode mounting structure, including an ignition needle body and an electrode. The bottom of the ignition needle body is provided with an interconnected mounting groove and a rotating groove. The electrode is inserted into the mounting groove. A support lug protrudes from the side wall of the electrode, and the support lug is rotatably connected to the rotating groove. The mounting groove and the rotating groove form a limiting step in the vertical direction. The limiting step is used to limit the support lug. When the support lug enters the rotating groove, the electrode and the ignition needle body are bonded together with adhesive.
[0004] Optionally, the inner wall of the mounting groove is provided with a limiting part, the electrode plate includes an electrode plate body, the limiting part and the electrode plate body are rotatably abutted, the support ears are provided on both sides of the electrode plate body, and the limiting step is formed by the rotating groove and the limiting part.
[0005] Optionally, the mounting groove includes an opening whose length is adapted to the length of the electrode sheet, and whose width is greater than the width of the electrode sheet.
[0006] Optionally, a guide portion is provided on the side wall of the opening, which is used to guide the electrode sheet smoothly into the mounting groove.
[0007] Optionally, the cross-section of the rotating groove is fan-shaped.
[0008] Optionally, the rotation angle of the electrode sheet is 0-90 degrees.
[0009] Optionally, the depth of the mounting groove is less than the height of the electrode plate, and when the electrode plate is inserted into the mounting groove, the bottom of the electrode plate extends out of the mounting groove to facilitate rotation.
[0010] Optionally, the ignition needle body is made of ceramic material.
[0011] Compared to existing technologies, the electrode mounting structure of this utility model, by setting an mounting groove and a rotating groove, allows the electrode to be inserted into the mounting groove and then rotated, causing the electrode's support to rotate into the rotating groove. The limiting step formed between the mounting groove and the rotating groove restricts the vertical movement of the support, making it less likely for the electrode to fall out of the ignition needle even after the adhesive has aged, thus making the structure more stable.
[0012] In addition, this utility model provides an umbrella-shaped ignition needle, including the electrode plate mounting structure described above.
[0013] Compared with the prior art, the umbrella-shaped ignition needle of this utility model and the electrode plate mounting structure described above have the same advantages over the prior art, which will not be repeated here. Attached Figure Description

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0023] The accompanying drawings of the embodiments of this utility model provide a coordinate system XYZ, where the positive direction of the X-axis represents the left and the negative direction of the X-axis represents the right, the positive direction of the Y-axis represents the front and the negative direction of the Y-axis represents the back, the positive direction of the Z-axis represents the top and the negative direction of the Z-axis represents the bottom.
[0024] This utility model embodiment provides an electrode plate mounting structure, as shown in Figures 1 to 6, including an ignition needle body and an electrode plate. The bottom of the ignition needle body is provided with an interconnected mounting groove and a rotating groove. The electrode plate is inserted into the mounting groove. A support lug is protruding on the side wall of the electrode plate. The support lug is rotatably connected to the rotating groove. The mounting groove and the rotating groove form a limiting step in the vertical direction. The limiting step is used to limit the support lug. When the support lug enters the rotating groove, the electrode plate and the ignition needle body are bonded together with adhesive.
[0025] As shown in Figures 4 and 5, in this embodiment, the electrode sheet is integrally formed. When the ignition needle is installed and in use, the electrode sheet is located at the bottom of the ignition needle. A limiting step abuts against the lower part of the support lug to prevent the lug from moving downwards.
[0026] Compared to existing technologies, the electrode mounting structure of this utility model, by setting an mounting groove and a rotating groove, allows the electrode to be inserted into the mounting groove and then rotated, causing the electrode's support to rotate into the rotating groove. The limiting step formed between the mounting groove and the rotating groove restricts the vertical movement of the support, making it less likely for the electrode to fall out of the ignition needle even after the adhesive has aged, thus making the structure more stable.
[0027] Optionally, the inner wall of the mounting groove is provided with a limiting part, the electrode plate includes an electrode plate body, the limiting part and the electrode plate body are rotatably abutted, the support ears are provided on both sides of the electrode plate body, and the limiting step is formed by the rotating groove and the limiting part.
[0028] As shown in Figure 5, in this embodiment, the electrode sheet has a sheet-like structure, with lugs located on the upper left and right sides of the electrode sheet body. The length of the line connecting the ends of the two lugs is greater than the width of the electrode sheet body. A limiting part is located below the rotating groove to restrict the downward movement of the lugs. The inner wall of the limiting part and the side wall of the electrode sheet body rotate and abut against each other.
[0029] As shown in Figure 6, optionally, the mounting groove includes an opening, the length of which is adapted to the length of the electrode sheet, and the width of the opening is greater than the width of the electrode sheet.
[0030] Optionally, a guide portion is provided on the side wall of the opening, which is used to guide the electrode sheet smoothly into the mounting groove.
[0031] As shown in Figures 3 and 6, in this embodiment, there are two guide parts, which are respectively disposed on the front and rear inner sidewalls of the opening. Both guide parts are provided with inclined guide surfaces. The opening cooperates with the guide parts to enable the electrode sheet to be pre-positioned when inserted into the mounting slot, making the insertion more convenient.
[0032] As shown in Figure 6, optionally, the cross-section of the rotating groove is fan-shaped. In this embodiment, the radius of the fan shape is less than half the length of the opening.
[0033] As shown in Figure 6, optionally, the rotation angle of the electrode sheet is 0-90 degrees. In this embodiment, the maximum rotation angle of the electrode sheet is 60 degrees.
[0034] As shown in Figure 5, optionally, the depth of the mounting groove is less than the height of the electrode plate, and when the electrode plate is inserted into the mounting groove, the bottom of the electrode plate extends out of the mounting groove to facilitate rotation.
[0035] Optionally, the ignition needle body is made of ceramic. The electrode plate is made of high-performance alloy material (such as nickel-chromium alloy, platinum coating) or ceramic composite material, reducing electrode plate wear under high temperature and gas corrosion and extending its service life. Furthermore, the electrode plate surface is coated with an anti-oxidation coating (such as silver plating, ceramic spraying) to reduce carbon deposits or oil adhesion and ensure stable electric spark conduction.
[0036] Another embodiment of this utility model provides an umbrella-shaped ignition needle, including the electrode plate mounting structure described above.
