Each movable shaft is cylindrical, and one end of each movable shaft extends to the outer side of the limiting ring. A pressing block is fixedly connected to the end of the movable shaft outside the limiting ring.

[0010] One side of the extrusion block is set as an inclined surface, and the inclined surface of the extrusion block gradually extends outward in a direction away from the screw ring. The side of the extrusion block slides and limits the movement of the inner wall of the burner.

[0027] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] like Figure 1-5As shown, a maintenance-friendly burner includes a conveying mechanism 1, with a disassembly / assembly mechanism 2 on one side of the conveying mechanism 1; it also includes: the disassembly / assembly mechanism 2 comprising a burner 201, with an external thread on the middle section of the outer wall of the burner 201, a screw ring 204 sleeved on the middle section of the outer wall of the burner 201, an internal thread on the inner wall of the screw ring 204, and the inner wall of the screw ring 204 being threaded along the surface of the burner 201; wherein, a limiting ring 205 is formed on the outer side of one side of the screw ring 204, and the inner side of the limiting ring 205... Movable shafts 206 are slidably connected around the perimeter of the burner 201, and each movable shaft 206 is cylindrical. One end of each movable shaft 206 extends to the outside of the limiting ring 205, and a pressing block 207 is fixedly connected to the end of the movable shaft 206 outside the limiting ring 205. One side of the pressing block 207 is a slope, which gradually extends outward away from the screw ring 204. The side of the pressing block 207 slides and limits the movement of the inner wall of the burner 201. Figure 2 As shown, when the extrusion block 207 moves to the right, the inclined side of the extrusion block 207 applies a force to the extrusion plate 208 toward the protective sleeve 202.

[0029] A protective sleeve 202 is fixedly installed in the middle of the inner wall of the burner 201. The burner 201 and the protective sleeve 202 are aligned in the same length direction. A retaining ring 203 is fixedly connected to the bottom of one side of the burner 201. A through groove is formed in the middle of the inner wall of the retaining ring 203, and the through groove in the inner wall of the retaining ring 203 is arc-shaped. Figures 1-2 As shown, the protective sleeve 202 is made of silicon carbide, which helps to protect the burner 201 from corrosion damage and extend the life of the burner 201;

[0030] The inner wall of the burner 201 is also slidably connected with baffles 210. One end of each baffle 210 near the central axis of the burner 201 is connected through to the inner wall of the protective sleeve 202, and the other end of each baffle 210 is close to one side of the inclined surface of the extrusion block 207. Figure 2 , Figure 4 As shown, the stop 210 moves toward the inside of the protective sleeve 202, thereby reducing the outlet size of the burner 201;

[0031] Each stop 210 has a pressing plate 208 fixedly connected to the end furthest from the protective sleeve 202. A spring 209 is fixedly connected to one end of the pressing plate 208, and the other end of the spring 209 is fixedly connected to the inner wall of the burner 201. The outer surface of the pressing plate 208 also makes movable contact with one side of the inclined surface of the pressing block 207. Figure 2 As shown, the spring 209 pushes each extrusion piece 208 away from the protective sleeve 202;

[0032] The conveying mechanism 1 includes an air housing 101, with a gas housing 102 connected to one end of the bottom surface of the air housing 101. A conveying chamber 103 is formed in the middle inner wall of the air housing 101, and a mounting groove 104 is formed on the side of the air housing 101. A knob 105 is rotatably connected to the outer wall of the air housing 101 below the mounting groove 104. A stop plate 106 is fixedly installed on the top center of the knob 105, penetrating the inner wall of the air housing 101. A torsion spring 107 is fixedly connected to the bottom surface of the stop plate 106 outside the pivot of the knob 105. The bottom of the torsion spring 107 is fixedly connected to the inner wall of the air housing 101. The inner wall of the mounting groove 104 is inserted into the burner 201, and the side wall of the stop plate 106 is in movable contact with the inner wall of the stop ring 203. Figure 1 As shown, the torsion spring 107 pushes the abutment plate 106 to rotate back to its original position, thereby keeping the abutment plate 106 in place. Figure 5 As shown in the figure, the stop ring 203 is locked in place.

[0033] The working principle of this utility model:

[0034] When disassembling the burner 201 for replacement or maintenance, rotate the knob 105 to separate the abutment ring 203 from the screw ring 204, thereby unlocking the abutment ring 203 inside the burner 201. Then pull the burner 201 out in a direction away from the mounting groove 104.

[0035] Secondly, when adjusting the outlet size of the burner 201, the rotating ring 204 moves linearly along the middle section of the burner 201 under the action of the thread. During this period, the movable shaft 206 moves along the inner side of the limiting ring 205, and the extrusion block 207 moves towards the extrusion plate 208. When the inclined side of the extrusion block 207 contacts the extrusion plate 208, it applies a force to the extrusion plate 208 and the stop block 210 toward the middle of the burner 201, so that the stop block 210 extends into the protective sleeve 202 and reduces the cross-sectional size of the outlet of the burner 201. When the rotating ring 204 rotates in the opposite direction and moves back to its original position, the spring 209 releases its elastic potential energy and extends. The spring 209 pushes the extrusion plate 208 and then drives the stop block 210 to reset.

[0036] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
