Abstract
Description
Technical Field
[0001] This utility model relates to the field of burner accessories, and in particular to a burner needle structure that can be quickly disassembled and assembled. Background Technology
[0002] Existing burner needle structures include a needle body, a base, and a wire. The bottom of the needle body is inserted into the top of the base, and the needle body and base are fixedly connected. The top of the wire is inserted into the base and connects to the needle body. The base is detachably connected to the burner, for example, by snap-fit, threaded connection, or screw installation. When the needle body is damaged, the wire needs to be cut, and then the entire needle body structure needs to be disassembled, meaning the needle body, base, and the wire connecting the base must all be replaced. This results in high maintenance costs, and the wire connection is prone to leakage, posing a safety hazard. Furthermore, the wire needs to be hidden inside the burner, making the disassembly and reassembly process time-consuming and labor-intensive, leading to low maintenance efficiency. Summary of the Invention
[0003] The purpose of this invention is to provide a burner needle structure that can be quickly disassembled and assembled, which is convenient, efficient, low in maintenance cost, and safe to use.
[0004] To achieve this objective, the present invention adopts the following technical solution: a burner needle body structure that can be quickly disassembled and assembled, including a needle body, a base, and a wire. The bottom of the needle body is inserted into the top of the base, and the top of the wire is inserted into the base to connect to the needle body. The invention also includes a ceramic body, with the needle body inserted through and fixed within the ceramic body. The top of the needle body protrudes from the ceramic body, and the bottom of the ceramic body is inserted into the base. The bottom of the needle body protrudes from the ceramic body to connect to the wire. Furthermore, a fixing sleeve is included to press the bottom of the ceramic body within the base. The fixing sleeve is detachably connected to the base. During maintenance, the fixing sleeve is removed from the base, and the ceramic body with the needle body can then be removed and replaced. Therefore, only the ceramic body with the needle body needs to be replaced; there is no need to disassemble and replace the base and wire. The maintenance process is very simple, fast, efficient, and low-cost. It eliminates the need to cut the wire, avoids damaging the wire, avoids adding connection points, and effectively eliminates the safety hazards associated with adding connection points.
[0005] Furthermore, a first protruding edge is formed at the bottom of the ceramic body, and a limiting protruding edge is formed on the inner wall of the top of the fixing sleeve to block the first protruding edge. The inner wall of the bottom of the fixing sleeve is threaded to the outer wall of the top of the base. This design is simple in structure and easy to assemble and disassemble.
[0006] Furthermore, the elastic element is pressed between the first protrusion and the limiting protrusion, improving the stability of the ceramic body installation.
[0007] Furthermore, the elastic element is a spring.
[0008] Furthermore, the base has an annular sleeve structure, with an insert ring formed at the top. The inner wall thickness of the insert ring is thinner than the inner wall thickness of the base, thus forming an inner annular recess within the insert ring and an outer annular recess outside the insert ring. A first protruding edge is pressed into the inner annular recess under the action of an elastic element, with its bottom pressed against the top wall of the base. The bottom of the fixing sleeve is inserted into the outer annular recess, and its bottom is also pressed against the top wall of the base. The fixing sleeve is threaded to the outer wall of the insert ring. This insert ring and outer annular recess design further increases the contact area of the fixing sleeve, restricts its installation position, and improves installation stability. Moreover, the inner annular recess also restricts the installation position of the first protruding edge, ensuring accurate installation of the ceramic body.
[0009] Furthermore, a mounting edge is formed on the bottom periphery of the base, and mounting holes are provided on the mounting edge. Screws are installed in the mounting holes to connect to the burner, facilitating the assembly and disassembly of the entire base.
[0010] The beneficial effects of this utility model are as follows: when damaged, the damaged ceramic body and needle body can be disassembled and replaced by removing the fixing sleeve, without the need to disassemble and replace the base and wires; this greatly reduces maintenance costs, and the disassembly and assembly speed is fast and efficient, without damaging the wires, avoiding the increase of connection points, preventing the risk of leakage caused by connection points, and ensuring safe use.

[0019] like Figure 1-4 As shown, a quick-assembly and disassembly burner needle structure includes a needle body 1, a base 2, and a wire 3. The bottom of the needle body 1 is inserted into the top of the base 2, and the top of the wire 3 is inserted into the base 2 to connect to the needle body 1. These are similar to existing burner needle structures.
[0020] The difference in this product is that it adds a ceramic body 4 and a fixing sleeve 5. The ceramic body 4 is made of ceramic and is cylindrical in shape. The needle body 1 is inserted into and fixed inside the ceramic body 4. This fixing method can be glue. The top of the needle body 1 protrudes from the ceramic body 4, and the bottom of the ceramic body 4 is inserted into the base 2. The bottom of the needle body 1 protrudes from the ceramic body 4 to form a tip. This tip is inserted into the top of the wire 3, thereby realizing the connection between the wire 3 and the needle body 1.
[0021] The fixing sleeve 5 presses the bottom of the ceramic body 4 into the base 2, and the fixing sleeve 5 is detachably connected to the base 2. Specifically, as shown... Figure 1 As shown, a first protruding edge 41 is formed at the bottom of the ceramic body 4, and this first protruding edge 41 is annularly arranged on the outer periphery of the bottom of the ceramic body 4. The fixing sleeve 2 has a cover structure, that is, a first hole is formed in the middle of the fixing sleeve 5, through which the ceramic body 4 passes. A limiting protruding edge 21 is formed on the inner wall of the top of the fixing sleeve 5. This limiting protruding edge 21 is located outside the first hole and is also annular. The limiting protruding edge 21 is located directly above the first protruding edge 41, thereby blocking the first protruding edge 41 and fixing the first protruding edge 41 in the base 2. It is best to press an elastic member 6 between the first protruding edge 41 and the limiting protruding edge 21. The elastic member 6 is a spring. The inner wall of the bottom of the fixing sleeve 2 is threaded to the outer wall of the top of the base 2. The detailed structure is that the base 2 is an annular sleeve structure, and an insert ring 22 is formed on the top of the base 2. The inner wall thickness of the insert ring 22 is thinner than the inner wall thickness of the base 2, that is, the thickness of the insert ring 22 is one-third of the thickness of the base. That is, part of the top surface of the base 2 is located inside the insert ring 22 and part is located outside the insert ring 22, thus forming an inner annular recess 23 inside the insert ring 22 and an outer annular recess 24 outside the insert ring 22. The first protruding edge 41 is pressed into the inner annular recess 23 under the action of the elastic member 6, and the bottom of the first protruding edge 41 is pressed against the top wall of the base 2. The bottom of the fixing sleeve 5 is inserted into the outer annular recess 24, and the bottom of the fixing sleeve 5 is also pressed against the top wall of the base 2. The fixing sleeve 5 is threaded to the outer wall of the insert ring 22, that is, the lower inner wall of the fixing sleeve 5 is provided with internal threads, and the outer wall of the insert ring 22 is provided with external threads.
[0022] To facilitate the assembly and disassembly of the base, a mounting edge 25 is formed on the bottom periphery of the base 2, and mounting holes 26 are provided on the mounting edge 25. A protrusion is provided on the lower part of the inner wall of the base 2, which presses against the outer wall of the wire 3, thereby pressing and fixing the wire 3 into the base 1.
[0023] When the needle body 1 is damaged, rotate the fixing sleeve 5 counterclockwise. The spring will return to its original position and extend, pushing the rotating sleeve upwards and separating the fixing sleeve 5 from the base 2. At this time, the ceramic body 4 can be pulled upwards, allowing the needle body 1 to detach from the wire 3. Then remove the ceramic body 4 and the fixing sleeve 5. The ceramic body and the needle body 1 are fixed together. Separate the ceramic body 4 and the fixing sleeve 5 and remove the spring. Then replace it with a new ceramic body 4 with the needle body 1. Put the spring on the ceramic body 4, with the bottom of the spring contacting the first protrusion 41. Put the new ceramic body 4 with the needle body 1 into the inner annular recess 23. Then put the fixing sleeve 5 on the top of the ceramic body 4 and rotate the fixing sleeve 5 clockwise. The bottom of the fixing sleeve 5 is threaded to the outer wall of the insertion ring 22 until the fixing sleeve 5 is just inside the outer annular recess 24. The limiting protrusion 21 of the fixing sleeve 5 also presses the spring against the first protrusion 41, thus completing the replacement.
[0024] When this product is damaged, only the damaged needle body 1 and ceramic body 4 need to be replaced. Moreover, the replacement only requires disassembling and assembling the fixing sleeve 5, without disassembling and assembling the entire base 2, which is very convenient.
[0025] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
