The outlet pipe and the ignition needle are disposed on the upper part of the mounting platform. The ignition needle is disposed on the side of the outlet pipe. A fixing sleeve is disposed on the surface of the mounting platform corresponding to the ignition needle. The bottom of the ignition needle is rotatably inserted into the fixing sleeve. An adjustment groove is provided on the mounting platform. The fixing sleeve is inserted into the adjustment groove and can reciprocate along the length of the adjustment groove. A rotation adjustment mechanism for driving the fixing sleeve to rotate is also disposed on the side of the mounting platform corresponding to the adjustment groove.
[0006] By adopting the above technical solution: rotating the ignition needle to move the upper end of the ignition needle toward the gas outlet hole on the gas pipe, and rotating the adjustment mechanism to swing and adjust the ignition needle on the side of the gas outlet pipe, the tip of the ignition needle is aligned with the gas outlet hole of the gas outlet pipe after the cooperation of the above structure, thus extending the service life of the ignition needle.
[0007] Furthermore, the first fixing seat has a mounting hole communicating with the sleeve, and the mounting platform is fixedly installed on the mounting hole to seal the mounting hole. The lower part of the side wall of the sleeve is fixedly fitted with a second fixing seat.

Figure 1 and Figure 2As shown, the upper part of the first fixing seat 2 has an upwardly protruding mounting platform 21 that seals the mounting hole 23. The gas outlet pipe 4 and the ignition needle 5 are located on the upper part of the mounting platform 21, and the ignition needle 5 is located on the side of the gas outlet pipe 4 to ignite the gas outlet pipe 4. The lower part of the side wall of the sleeve 1 is fixedly fitted with a second fixing seat 3, and the bottom of the sleeve 1 is fixedly installed on the burner through the second fixing seat 3. The lower part of the side wall of the sleeve 1 is also provided with a power connection port 11 and an air inlet 12 connected to the inside of the sleeve 1. The power connection port 11 and the air inlet 12 are located at the bottom of the second fixing seat 3. The bottom of the ignition needle 5 is connected to a conductive wire 51. The conductive wire 51 passes through the sleeve 1 and the power connection port 11 and extends outward to supply power to the ignition needle 5. The bottom of the gas outlet pipe 4 is connected to a gas guide pipe 41. The gas guide pipe 41 passes through the sleeve 1 and connects to the air inlet 12 to supply gas to the gas outlet pipe 4.
[0026] Moreover, refer to Figures 1-3 As shown, a fixing sleeve 6 is provided on the surface of the mounting platform 21 at a position corresponding to the ignition needle 5, and the bottom of the ignition needle 5 is rotatably inserted into the fixing sleeve 6. Multiple slots 61 are evenly distributed inside the fixing sleeve 6 to fix the rotational position of the ignition needle 5. The side wall of the ignition needle 5 has fixing blocks that cooperate with the slots 61. Rotating the ignition needle 5 causes the fixing blocks to engage in the corresponding slots 61, thus fixing the rotational position of the ignition needle 5.
[0027] Furthermore, referring to Figure 3 , Figure 4 and Figure 6As shown, an adjustment groove 22 is provided on the mounting platform 21. The adjustment groove 22 is connected to the sleeve 1. The length of the adjustment groove 22 is greater than the diameter of the fixed sleeve 6. The fixed sleeve 6 is inserted into the adjustment groove 22 and can reciprocate along the length of the adjustment groove 22 so that the upper end of the ignition needle 5 can be aligned with the gas outlet of the gas outlet pipe 4 for ignition. A rotation adjustment mechanism 7 for driving the fixed sleeve 6 to reciprocate is also provided on the side of the mounting platform 21 corresponding to the adjustment groove 22. Preferably, the rotation adjustment mechanism 7 includes an adjustment shaft 71 and a locking plate 74 provided on the side of the adjustment groove 22. Triangular truncated pyramids 72 are evenly distributed on the bottom surface of one end of the adjustment shaft 71.

The other end of the adjustment shaft 71 extends through the side wall of the adjustment groove 22 to the bottom of the fixed sleeve 6 and is fixedly connected to the fixed sleeve 6. The bottom of the locking plate 74 has a sliding rod, which is slidably connected to the first fixed seat 2. A first spring 76 is sleeved on the outer wall of the sliding rod. The first spring 76 is located between the locking plate 74 and the first fixed seat 2. The upper part of the locking plate 74 has a triangular connecting block 75 that cooperates with the triangular slot 73. The triangular connecting block 75 is engaged in the corresponding triangular slot 73 under the elastic force of the first spring 76, thereby fixing the rotational position of the adjusting shaft 71. In use, press down on the locking plate 74. The locking plate 74 moves downward against the elastic force of the first spring 76, causing the triangular connecting block 75 to move downward from the triangular slot 73. At this time, the adjusting shaft 71 is in an active state. Rotate the adjusting shaft 71 to make the fixing sleeve 6 rotate in the adjusting groove 22. After aligning the upper end of the ignition needle 5 with the air outlet in the air outlet pipe 4, release the locking plate 74. The triangular connecting block 75 is engaged in the corresponding triangular slot 73 under the elastic force of the first spring 76, thus fixing the rotation position of the adjusting shaft 71.
[0028] The connection method between the adjusting shaft 71 and the fixed sleeve 6 is as follows: Figure 6 As shown. A threaded shaft 62 is welded downwards from the bottom of the fixed sleeve 6. The threaded shaft 62 extends downwards through the adjusting shaft 71. A first nut 78 and a second nut 77 are screwed onto the threaded shaft 62. The first nut 78 and the second nut 77 are located on the upper and lower sides of the adjusting shaft 71, respectively. By locking the first nut 78 and the second nut 77 towards the adjusting shaft 71, the fixed sleeve 6 and the adjusting shaft 71 are fixedly connected. Furthermore, by setting the threaded shaft 62, the second nut 77, and the first nut 78, the installation height of the ignition needle 5 can be adjusted to meet the needs of the gas outlet pipe 4 at different heights. Also, when the ignition needle 5 deforms after long-term use, the height of the ignition needle 5 can be adjusted so that the upper end of the ignition needle 5 can be aligned with the gas outlet hole of the gas outlet pipe 4.
[0029] Reference Figure 6As shown, an elastic dustproof mechanism 8 is provided at the bottom of the mounting platform 21. The elastic dustproof mechanism 8 is movably clamped on the outside of the fixed sleeve 6 to seal the gap between the fixed sleeve 6 and the adjustment groove 22, preventing debris from falling into the sleeve 1 through the gap between the fixed sleeve 6 and the adjustment groove 22, which would make it difficult to clean. The structure of the elastic dustproof mechanism 8 includes a dustproof plate 81 and a second spring 85. Specifically, two dustproof plates 81 are symmetrically arranged on both sides of the adjustment groove 22. The dustproof plates 81 are slidably hung on the bottom of the mounting platform 21. The end of the dustproof plate 81 near the fixed sleeve 6 has a semi-circular connecting groove, which is clamped on the outer wall of the fixed sleeve 6. A connecting plate 82 is welded to the end of the dustproof plate 81 away from the fixed sleeve 6. A mounting plate 83 is arranged at the bottom of the mounting platform 21 corresponding to the connecting plate 82. A connecting shaft 84 is located on the connecting plate 82. The connecting shaft 84 passes through the mounting plate 83 and extends outward to form a sliding connection with the mounting plate 83. A second spring 85 is sleeved outside the connecting shaft 84. The second spring 85 is located between the mounting plate 83 and the connecting plate 82. Under the elastic force of the second spring 85, the dustproof plate 81 is clamped on the outer wall of the fixed sleeve 6. When adjusting the position of the ignition needle 5, during the movement of the fixed sleeve 6, the second spring 85 is set to keep the dustproof plate 81 clamped on the outer wall of the fixed sleeve 6 so that the dustproof plate 81 can always seal the gap between the fixed sleeve 6 and the adjustment groove 22.
[0030] When the ignition needle 5 deforms after prolonged use under high temperature conditions, rotating the ignition needle 5 causes the fixing block on the ignition needle 5 to engage in the corresponding slot 61, thus fixing the rotation position of the ignition needle 5. Rotating the adjusting shaft 71 in the rotation adjustment mechanism 7 causes the ignition needle 5 to swing and adjust on the side of the gas outlet pipe 4. Furthermore, rotating the first nut 78 and the second nut 77 adjusts the installation height of the ignition needle 5. Through the coordinated operation of the above structures, the top of the ignition needle 5 is aligned with the gas outlet hole of the gas outlet pipe 4, extending the service life of the ignition needle 5. During the movement of the ignition needle 5, the dustproof plate 81 in the elastic dustproof mechanism 8 is always clamped to the outside of the fixing sleeve 6 under the elastic force of the second spring 85, preventing debris from falling into the sleeve 1 through the gap between the fixing sleeve 6 and the adjusting groove 22.
