Abstract
Description
Technical Field
[0001] This utility model relates to the field of gas component technology, and in particular to a ceramic ignition needle that facilitates heat dissipation. Background Technology
[0002] An ignition needle is a key component in a device used to ignite combustible substances such as gas or fuel. It is usually made of materials that are resistant to high temperatures and high pressures, such as ceramics or metals.
[0003] When the ignition needle is working, it generates an electric spark to ignite the gas. This process generates a certain amount of heat. If the heat cannot be dissipated in time, the temperature of the ignition needle will become too high, which may lead to a decline in the performance of the ceramic material, such as reduced insulation performance and weakened mechanical strength, thus affecting the normal operation and service life of the ignition needle.
[0004] To address these issues, those skilled in the art have proposed a ceramic ignition needle that facilitates heat dissipation. Utility Model Content

[0012] As a preferred embodiment of the ceramic ignition needle for easy heat dissipation according to this utility model, the number of ignition mechanisms is two, the two ignition mechanisms are respectively installed on both sides of the connecting mechanism, and the ignition ends of the two ignition mechanisms are retracted inward.
[0013] As a preferred embodiment of the ceramic ignition needle for easy heat dissipation of this utility model, the ignition mechanism includes an insulating sleeve, which is installed on one side of the connecting mechanism. A rectangular groove is formed on the bottom outer wall of the insulating sleeve near the connecting mechanism, and an arc-shaped groove is formed on the surface of the rectangular groove. An ignition component is disposed in the arc-shaped groove.
[0014] As a preferred embodiment of the ceramic ignition needle for easy heat dissipation according to the present invention, the ignition assembly includes a ceramic needle sleeve, which is snapped onto the inner wall of the arc-shaped groove, and a metal electrode is inserted into the inner circumferential wall of the ceramic needle sleeve.
[0015] As a preferred embodiment of the ceramic ignition needle for easy heat dissipation according to this utility model, the front end and rear end of the metal electrode are exposed outside the ceramic needle sleeve, the front ends of the two metal electrodes are both drawn inward, and the rear ends of the metal electrodes are connected to the igniter.
[0016] As a preferred embodiment of the ceramic ignition needle for easy heat dissipation according to this utility model, the fixing mechanism includes two aluminum strips, which are installed on both sides of the rectangular groove near the ceramic needle sleeve. The same arc-shaped aluminum sheet is installed on the adjacent side of the two aluminum strips. The arc-shaped aluminum sheet is attached to the outer wall of the ceramic needle sleeve. There are mounting holes at both ends of the aluminum strips. Locking rods are inserted into the inner walls of the mounting holes. One end of the locking rod is inserted into the interior of the insulating sleeve.
[0017] As a preferred embodiment of the ceramic ignition needle for easy heat dissipation of this utility model, a plurality of heat dissipation fins are fixedly distributed at equal intervals on the bottom outer wall of the aluminum strip.
[0018] As a preferred embodiment of the ceramic ignition needle for easy heat dissipation of this utility model, the mounting mechanism includes a mounting plate, which is installed at the gas outlet, and two horizontal plates are installed at one end of the mounting plate.
[0019] As a preferred embodiment of the ceramic ignition needle for easy heat dissipation of this utility model, the connecting mechanism is installed on the surface of the two horizontal plates, the connecting mechanism includes a fixing frame and a heat dissipation component, the surface of the fixing frame has multiple hollow openings, and the heat dissipation component is installed inside the fixing frame.

Two sets of impellers are respectively facing the ignition mechanism on both sides.
[0021] The beneficial effects of this utility model of a ceramic ignition needle that facilitates heat dissipation are as follows: When the device is installed at the gas outlet, after successful ignition, the end of the metal electrode near the gas outlet causes the ignition mechanism to become too hot. The heat of the ignition mechanism will first be transferred to the insulating sleeve and ceramic needle sleeve through heat conduction. Its thermal conductivity is not as good as that of metal, but it still has a certain thermal conductivity. This avoids direct heat conduction through the metal electrode, thereby avoiding changes in the electric field distribution around the metal electrode and affecting ignition. The heat is transferred to the aluminum strip and the arc-shaped aluminum sheet through heat conduction, and then the heat is discharged to the outside through the heat dissipation fins, thereby reducing the temperature of the ignition mechanism and reducing the impact on the ignition mechanism.
[0022] When the metal electrode heats up, it emits energy outward in the form of thermal radiation. The aluminum strip and the arc-shaped aluminum sheet are within the range of the metal electrode's thermal radiation and absorb some of the energy from the thermal radiation, thereby increasing their own temperature and achieving the purpose of dissipating heat from the metal electrode.
[0023] Air cooling, which uses a motor to drive an impeller, can also dissipate heat from the ignition mechanism, thus ensuring that the ignition mechanism can work normally afterwards. Attached Figure Description

[0029] 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.
[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0031] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0032] Example 1
[0033] Reference Figure 1 and Figure 2 This is the first embodiment of the present utility model. This embodiment provides a ceramic ignition needle that facilitates heat dissipation, which can enhance the heat dissipation of the ceramic ignition needle and avoid affecting the effect of subsequent ignition work. It includes an installation mechanism 100, which is installed at the gas outlet.
[0034] A connecting mechanism 200 is provided on the mounting mechanism 100, and a heat dissipation component 202 is provided on the connecting mechanism 200;
[0035] An ignition mechanism 300 is mounted on the connecting mechanism 200. One end of the ignition mechanism 300 is near the gas outlet, and the other end is connected to an igniter.
[0036] The fixing mechanism 400 is installed on the ignition mechanism 300. The fixing mechanism 400 has the functions of reinforcing the fixing of the ignition mechanism 300 and conducting heat dissipation.
[0037] When the gas appliance starts its ignition process, the igniter converts low voltage to high voltage. The high voltage is transmitted to the ignition mechanism 300 through a wire, creating a strong electric field at the gas outlet. This strong electric field gives electrons in the air molecules near the exposed end enough energy to break free from atomic bonds and form free electrons and positive ions. This ionizes the air, creating plasma. The ionized air becomes a conductive channel, and electrons accelerate under the influence of the electric field, colliding with other atoms or molecules to generate more charged particles, forming an electric current and thus producing an electric spark. The generated electric spark has enough energy to give the gas molecules enough energy to start burning when it approaches the gas ejected from the gas outlet, thereby achieving the ignition function.
[0038] After ignition is completed, the igniter is turned off, and the gas equipment starts to burn continuously. The heat of the ignition mechanism 300 itself is conducted and dissipated through the fixing mechanism 400, and then the heat dissipation component 202 accelerates the heat dissipation of the ignition mechanism 300 by air cooling, so that the ignition mechanism 300 cools down and avoids affecting the subsequent operation.
[0039] Example 2
[0040] Reference Figures 1 to 3 This is the second embodiment of the present invention. Unlike the previous embodiment, there are two ignition mechanisms 300. The two ignition mechanisms 300 are respectively installed on both sides of the connecting mechanism 200, and the ignition ends of the two ignition mechanisms 300 are brought together inward.
[0041] Specifically, the ignition mechanism 300 includes an insulating sleeve 301, which is installed on one side of the connecting mechanism 200. A rectangular groove 304 is formed on the bottom outer wall of the insulating sleeve 301 near the connecting mechanism 200. An arc-shaped groove 305 is formed on the surface of the rectangular groove 304, and an ignition component is disposed in the arc-shaped groove 305.
[0042] Furthermore, the ignition assembly includes a ceramic needle sleeve 302, which is snapped onto the inner wall of the arc-shaped groove 305, and a metal electrode 303 is inserted into the inner circumferential wall of the ceramic needle sleeve 302.
[0043] The front and rear ends of the metal electrode 303 are exposed on the outside of the ceramic needle sleeve 302. The front ends of both metal electrodes 303 are drawn inward, and the rear ends of the metal electrodes 303 are connected to the igniter.
[0044] When the gas appliance starts the ignition process, the igniter converts the low voltage to a high voltage. The high voltage is transmitted to the metal electrode 303 through the wire. The high voltage forms a strong electric field on the metal electrode 303, generating an electric spark near the exposed end of the metal electrode 303. This spark comes into contact with the gas, thereby achieving the ignition function. The ceramic needle sleeve 302 is made of ceramic material with good high temperature resistance and insulation properties. Ceramic has good high temperature resistance and can maintain stable performance in high temperature environments. At the same time, it plays an insulating role to prevent current leakage.
[0045] The insulating sleeve 301 is fitted over the ceramic needle sleeve 302 and is usually made of insulating materials such as rubber or plastic. Its function is to further enhance the insulation performance, prevent the ignition mechanism 200 from short-circuiting with other components during operation, and also protect the ceramic needle sleeve 302 from external impacts and damage.
[0046] It should be noted that the fixing mechanism 400 includes two aluminum strips 402. The two aluminum strips 402 are installed on both sides of the rectangular groove 304 near the ceramic needle sleeve 302. The same arc-shaped aluminum piece 401 is installed on the adjacent side of the two aluminum strips 402. The arc-shaped aluminum piece 401 is attached to the outer wall of the ceramic needle sleeve 302. Both ends of the aluminum strips 402 have mounting holes. Locking rods 403 are inserted into the inner wall of the mounting holes. One end of the locking rod 403 is inserted into the interior of the insulating sleeve 301.
[0047] Among them, multiple heat dissipation fins 404 are fixedly distributed at equal intervals on the bottom outer wall of aluminum strip 402.
[0048] During use, the heat from the ignition mechanism is first transferred to the insulating sleeve 301 and the ceramic needle sleeve 302 through heat conduction, and then transferred to the aluminum strip 402 and the arc-shaped aluminum sheet 401 through heat conduction. The heat is then dissipated to the outside through the heat dissipation fins 404, thereby reducing the temperature of the ignition mechanism 200 and reducing the impact on the ignition mechanism 200.
[0049] Example 3
[0050] Reference Figure 1 and Figure 4 This is the third embodiment of the present utility model. Unlike the previous embodiment, the installation mechanism 100 includes an installation plate 101, which is installed at the gas outlet. Two horizontal plates 102 are installed at one end of the installation plate 101.
[0051] Specifically, the connecting mechanism 200 is installed on the surface of the two horizontal plates 102. The connecting mechanism 200 includes a fixing frame 201 and a heat dissipation component 202. The surface of the fixing frame 201 has multiple hollow openings, and the heat dissipation component 202 is installed inside the fixing frame 201.
[0052] Furthermore, the heat dissipation assembly 202 includes a motor 2021, which is installed inside the mounting bracket 201. One end of the output shaft of the motor 2021 is provided with a connecting shaft 2022, and an impeller 2023 is sleeved on the outer circumference of the connecting shaft 2022. The two sets of impellers 2023 are respectively facing the ignition mechanism 300 on both sides.
[0053] When in use, after starting the igniter, the motor 2021 can be started, which drives the connecting shaft 2022 and the impeller 2023 to rotate, and then the ignition mechanism 200 is cooled by blowing air for a short time, so that the heat is carried away from the ignition mechanism 200 and the temperature of the ignition mechanism 200 is reduced.
[0054] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.
[0055] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
