When a blockage appears on the top of the gas furnace combustion nozzle body 1, the gas furnace combustion nozzle body 1 is pressed down. At this time, the pressing spring 205 is squeezed and contracted, and the T-shaped clip 204 slides on the inner wall of the clip limiting groove 206. The clip limiting groove 206 limits the moving area of ​​the gas furnace combustion nozzle body 1. At this time, the nozzle anti-blocking cone 201 will push out the blockage on the top of the gas furnace combustion nozzle body 1 to ensure the cleanliness of the top of the gas furnace combustion nozzle body 1. Release the gas furnace combustion nozzle body 1, and under the elastic action of the pressing spring 205, the gas furnace combustion nozzle body 1 returns to its initial position.

[0028] See also Figure 3 As shown, a gas furnace combustion nozzle, a nozzle height adjustment component 3, includes a height adjustment shell 301, a threaded groove 302, a threaded rod 303, and a gas delivery base 304. The height adjustment shell 301 forms a lifting structure with the gas delivery base 304 through the threaded groove 302, the threaded rod 303, and the threaded connection is formed between the threaded groove 302 and the threaded rod 303, which is convenient for adjusting the height of the gas furnace combustion nozzle body 1 and improving the ignition efficiency of the gas furnace combustion nozzle body 1.

The fixed arc clamp block 405 constitutes a rotating structure, which is convenient for rotating the height adjustment shell 301, and the operation is simple, without the aid of external objects. The auxiliary folding rod 401 rotates around the folding rod shaft 402, and the movable arc clamp block 403 rotates around the clamp block shaft 404 under the action of force. When the auxiliary folding rod 401 leaves the movable arc clamp block 403, the movable arc clamp block 403 returns to its initial position under the elastic action of the clamp block spring 406.

[0030] Working principle: First, install the device and test the ignition efficiency. The height of the gas furnace combustion nozzle body 1 will affect the ignition efficiency, so the height of the gas furnace combustion nozzle body 1 needs to be adjusted, and the auxiliary folding rod 401 is rotated around the folding rod rotating shaft 402. Under the action of force, the movable arc clamping block 403 is rotated around the clamping block rotating shaft 404. When the auxiliary folding rod 401 leaves the movable arc clamping block 403, the movable arc clamping block 403 returns to its initial position under the elastic action of the clamping block spring 406. When the auxiliary folding rod 401 is perpendicular to the height adjustment shell 301, the auxiliary folding rod 401 is rotated. At the same time, the height adjustment shell 301 starts to rotate under the action of the auxiliary folding rod 401, and the screw between the threaded groove 302 and the threaded rod 303 is used to adjust the height of the gas furnace combustion nozzle body 1. The height of the height-adjusting shell 301 can be adjusted through the thread connection, so that the height position of the gas furnace combustion nozzle body 1 can be adjusted. Then, during daily use of the device, when a blockage is found on the top of the gas furnace combustion nozzle body 1, the gas furnace combustion nozzle body 1 is pressed down. At this time, the pressing spring 205 is squeezed and contracted, and the T-shaped clip 204 slides on the inner wall of the clip limiting groove 206. The clip limiting groove 206 limits the moving area of ​​the gas furnace combustion nozzle body 1. At this time, the nozzle anti-blocking cone 201 will push out the blockage on the top of the gas furnace combustion nozzle body 1 to ensure the cleanliness of the top of the gas furnace combustion nozzle body 1. The gas furnace combustion nozzle body 1 is released, and under the elastic action of the pressing spring 205, the gas furnace combustion nozzle body 1 returns to its initial position.
