Description

Technical Field

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

[0002] The ignition needle is an important component of household appliances such as gas stoves or gas ovens. The high voltage electricity generated by the pulse igniter is transmitted to the electrode needle head through the wire, and a discharge phenomenon is generated between the electrode needle head and the burner, thereby igniting the gas. In existing gas appliances, the ignition needle is usually installed in a fixed length. However, since the same style of ignition needle cannot adapt to the ignition height requirements of burners of different heights, operators need to equip different ignition needles according to different styles of burners. The disassembly and installation process is cumbersome and the usage scenarios are relatively limited. In addition, the existing pulse wire is directly plugged into the tail needle of the ignition needle, which is easy to loosen and fall off when pulled, affecting ignition. In addition, the electrode needle head of the existing ignition needle is directly exposed to the air and is easily damaged by impact. In order to solve the above problems, a ceramic ignition needle is needed.

[0003] The existing ceramic ignition needle cannot protect the electrode needle head, cannot adjust the height of the ignition needle, and cannot prevent the pulse wire from falling off during operation. Therefore, a ceramic ignition needle is urgently needed. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a ceramic ignition needle to solve the problems that the existing ceramic ignition needle cannot protect the electrode needle head, cannot adjust the height of the ignition needle, and cannot prevent the pulse wire from falling off when in use.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a ceramic ignition needle, comprising an ignition needle body, an outer wall of the ignition needle body is installed with a clamping ring, and an outer wall of the clamping ring is installed with a protective sleeve.

[0006] A positioning sleeve is installed on the outer wall of the ignition needle body, a limit plate is installed on the outer wall of the ignition needle body, a limit spring is installed on the outer wall of the limit plate, and a limit sleeve is installed on the outer wall of the limit spring.

[0007] A tail needle is installed at the bottom of the ignition needle body, a pulse wire is installed on the outer wall of the tail needle, and a fixing sleeve is installed on the outer wall of the pulse wire.

[0008] Preferably, the clamping ring fits tightly with the protective sleeve, and the protective sleeve is made of rubber material.

[0009] Preferably, the positioning sleeve is threadedly connected to the ignition needle body, and the limit spring is movably connected to the ignition needle body.

[0010] Preferably, the limiting sleeve forms a telescopic structure through a limiting spring and a limiting plate, and the limiting spring and the limiting sleeve are welded.

[0011] Preferably, the pulse wire is sleeved with a fixing sleeve, and the fixing sleeve is threadedly connected with the ignition needle body.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model provides a clamping ring and a protective sleeve. Since the electrode needle head of the existing ignition needle body is directly exposed to the air, when the ignition needle body falls or is hit by an external force, the electrode needle head is easily damaged, affecting the use of the ignition needle body. The protective sleeve is sleeved with the top of the ignition needle body and fixed by the clamping ring, so as to protect the electrode needle head of the ignition needle body, avoid damage to the electrode needle head, and extend the service life of the ignition needle body.

[0014] 2. The utility model inserts the ignition needle body from bottom to top into the fixing ring of the stove by means of the positioning sleeve, limiting plate, limiting spring and limiting clamping sleeve, and adjusts the height of the ignition needle body by rotating the positioning sleeve and the ignition needle body to meet the ignition requirements of different stoves. At the same time, when the height of the ignition needle body is adjusted by the positioning sleeve, the limiting spring pushes the limiting clamping sleeve through its own elastic force to fit closely with the bottom of the fixing ring of the stove, thereby exerting a downward force on the ignition needle body. With the use of the positioning sleeve, the ignition needle body has better stability in the fixing ring of the stove.

[0015] 3. The utility model provides a tail pin, a pulse wire and a fixing sleeve, wherein the pulse wire is passed through the interior of the fixing sleeve, and then the pulse wire is plugged into the tail pin, and then the fixing sleeve is fixed to the bottom thread of the ignition needle body, thereby squeezing and fixing the pulse wire to prevent the pulse wire from being pulled off by external force, thereby causing the ignition needle body to be unable to ignite, and improving the stability of the connection between the tail pin and the pulse wire.

Through the arrangement of the clamp ring 2 and the protective sleeve 3, since the electrode needle head of the existing ignition needle body 1 is directly exposed to the air, when the ignition needle body 1 falls or is hit by external force, it is easy to cause damage to the electrode needle head, affecting the use of the ignition needle body 1. By sleeve-connecting the protective sleeve 3 with the top of the ignition needle body 1 and fixing it by the clamp ring 2, the electrode needle head of the ignition needle body 1 is protected, the electrode needle head is prevented from being damaged, and the service life of the ignition needle body 1 is extended.

[0023] See also Figure 1-3 A ceramic ignition needle, the outer wall of the ignition needle body 1 is installed with a positioning sleeve 4, the outer wall of the ignition needle body 1 is installed with a limiting plate 5, the outer wall of the limiting plate 5 is installed with a limiting spring 6, the outer wall of the limiting spring 6 is installed with a limiting sleeve 7, the positioning sleeve 4 is threadedly connected to the ignition needle body 1, the limiting spring 6 is movably connected to the ignition needle body 1, the limiting sleeve 7 forms a telescopic structure with the limiting plate 5 through the limiting spring 6, the limiting spring 6 is welded to the limiting sleeve 7, and the positioning sleeve 4, the limiting plate 5, the limiting spring 6 and the limiting sleeve 7 are arranged. The ignition needle body 1 is inserted into the fixing ring of the stove from bottom to top, and the height of the ignition needle body 1 is adjusted by rotating the positioning sleeve 4 and the ignition needle body 1 for thread adjustment to meet the ignition requirements of different stoves. At the same time, when the height of the ignition needle body 1 is adjusted by the positioning sleeve 4, the limit spring 6 pushes the limit sleeve 7 through its own elastic force to fit tightly with the bottom of the fixing ring of the stove, thereby exerting a downward force on the ignition needle body 1. The use of the positioning sleeve 4 makes the ignition needle body 1 have better stability in the fixing ring of the stove.

[0024] See also Figure 1-3A ceramic ignition needle, a tail needle 8 is installed at the bottom of the ignition needle body 1, a pulse wire 9 is installed on the outer wall of the tail needle 8, a fixing sleeve 10 is installed on the outer wall of the pulse wire 9, the pulse wire 9 is sleeved with the fixing sleeve 10, and the fixing sleeve 10 is threadedly connected with the ignition needle body 1. Through the provided tail needle 8, pulse wire 9 and fixing sleeve 10, the pulse wire 9 is passed through the interior of the fixing sleeve 10, and then the pulse wire 9 is plugged with the tail needle 8, and then the fixing sleeve 10 is threadedly fixed to the bottom of the ignition needle body 1, so as to squeeze and fix the pulse wire 9, prevent the pulse wire 9 from being pulled off by external force, thereby causing the ignition needle body 1 to fail to ignite, and improve the stability of the connection between the tail needle 8 and the pulse wire 9.

[0025] Working principle: When in use, first move the device to the desired position. Then, since the electrode needle head of the existing ignition needle body 1 is directly exposed to the air, when the ignition needle body 1 is out of use, it falls to the ground or is hit by external force, which can easily cause damage to the electrode needle head, affecting the use of the ignition needle body 1.
