[0013] Compared with the prior art, the present invention has the following beneficial effects: When the user is using the device for combustion, the user turns the handle, and the handle rotates the transmission rod through the worm and worm wheel, and the pull rope is wound through the transmission rod, so that the sealing plate is no longer in contact with the sealing buffer. At the same time, the second spring can be compressed through the sealing plate. At this time, the fuel or air passes through between the sealing plate and the valve body, thereby realizing the supply of fuel or air. When the user needs to cut off the fuel or air, at this time, he only needs to lift the handle and the worm, so that the worm wheel and the worm are no longer engaged. At this time, under the action of the second spring, the sealing plate pulls the pull rope to reset, so that the transmission rod and the worm wheel rotate in the opposite direction until one side of the sealing plate is tightly fitted with the sealing buffer. At this time, the fuel or air can be cut off instantly, which can effectively avoid accidents and thus improve safety. The fuel enters the interior of the first pipeline through the fourth pipeline, and the air enters between the third pipeline and the first pipeline through the second pipeline and the fourth pipeline. The fuel is discharged outwardly at an angle under the action of the diverter fan blades and the first diverter port. The fuel can be fully mixed with the air between the third pipeline and the first pipeline when passing through the diverter plate and the second diverter port. The fully mixed fuel and air can be discharged through the diverter plate and the second diverter port. At the same time, the fuel and air mixture discharged from different second diverter ports can be ignited by the igniter. At this time, the flame sprayed by the device is in a swirl shape. The fuel and air mixture can be evenly sprayed through the evenly distributed diverter plates and the second diverter ports, so that the fuel can be fully burned in all directions, avoiding local high pressure inside the furnace body. Temperature, by improving the diffusion mode of the fuel and air mixture, not only can the combustion speed be accelerated, but also the burnout rate can be improved, and at the same time, the fuel consumption can be effectively reduced, thereby achieving the effect of energy saving, consumption reduction, cost reduction and efficiency improvement. Before the fuel and air mixture is sprayed out through the second diversion port, the igniter starts working until it is ignited. After the ignition is completed, the user controls the output end of the second electric push rod to shorten. At this time, the second electric push rod drives the lower pressure plate to move up, and the ignition seat moves downward under the action of the first spring. The ignition seat drives the igniter to move down until the igniter is completely inside the receiving groove. At this time, the connecting rod is in a horizontal state. Retracting the igniter can prevent it from being burned by flames for a long time, thereby increasing its service life. When the user needs to perform inspection and maintenance, the user first The bolts between the closing plate and the mounting plate are removed, and then the user controls the motor to work. The motor can move the stabilizing block, the closing plate, the second pipe and the fourth pipe to the side away from the furnace body through the threaded rod and the receiving threaded sleeve. At this time, the stabilizing block slides on the top of the sliding rod. The stability of the movement of the closing plate, the second pipe and the fourth pipe is improved by the stabilizing block and the sliding rod. When the receiving threaded sleeve and the closing plate move to one side of the motor, the user controls the movement of the push plate through the first electric push rod so that the bottom end of the latch is no longer inside the receiving threaded sleeve. At this time, the user can remove the closing plate, the second pipe and the fourth pipe, thereby facilitating the user to inspect and maintain the third pipe, the first pipe and the refractory base. After the user has completed the inspection and maintenance, put them into the top of the bracket.Make the slide rod inside the stabilizing block, and also make the receiving threaded sleeve inside the buckle groove at the bottom end of the stabilizing block. Then the user inserts the pin into the receiving threaded sleeve through the first electric push rod to complete the limit work. The user resets the closing plate, the second pipe and the fourth pipe through the motor and the threaded rod, and finally tightens them with bolts. This device is not only convenient for users to carry out inspection and maintenance, but also can quickly cut off the air or fuel, thereby improving its safety of use. At the same time, this device can also ensure the spraying and combustion of fuel in all directions without dead ends, avoiding local high temperature inside the furnace body, thereby improving the fuel effect and product yield, and at the same time can effectively reduce fuel consumption, thereby achieving the effect of energy saving, consumption reduction, cost reduction and efficiency improvement.

The worm wheel 45 and the worm 46 can also complete self-locking, so as to ensure that the air or gas continues to flow. When the user needs to cut off the fuel or air, at this time, only the handle 2 and the worm 46 need to be turned up The worm gear 45 and the worm 46 are no longer meshed. At this time, the sealing plate 38 pulls the pull rope 44 to reset under the action of the second spring 41, so that the transmission rod 43 and the worm gear 45 rotate in the opposite direction until one side of the sealing plate 38 is tightly fitted with the sealing buffer 37. At this time, the fuel or air can be cut off instantly, which can effectively avoid accidents and thus improve safety. The fuel enters the interior of the first pipeline 20 through the fourth pipeline 19, and the air enters between the third pipeline 18 and the first pipeline 20 through the second pipeline 14 and the fourth pipeline 19. The fuel is discharged outwardly at an angle under the action of the blades of the diverter fan 21 and the first diverter port 22. When the fuel passes through the diverter plate 23 and the second diverter port 24, it can be connected with the air between the third pipeline 18 and the first pipeline 20 The fully mixed fuel and air can be discharged through the diverter plate 23 and the second diverter port 24, and the fuel and air mixture discharged from the different second diverter ports 24 can be ignited by the igniter 28. At this time, the flame sprayed out by the device is in a swirl shape, and the fuel and air mixture can be evenly sprayed through the evenly distributed diverter plate 23 and the second diverter port 24, so that the fuel can be fully burned in all directions, avoiding local high temperature inside the furnace body 1. By improving the diffusion mode of the fuel and air mixture, not only the combustion speed can be accelerated, but also the burnout rate can be improved, and at the same time, the fuel consumption can be effectively reduced, thereby achieving the effect of energy saving, consumption reduction, cost reduction and efficiency improvement. Before the fuel and air mixture is sprayed out through the second diverter port 24, the ignition The igniter 28 starts to work until it is ignited. After the ignition is completed, the user controls the output end of the second electric push rod 34 to shorten. At this time, the second electric push rod 34 drives the lower pressure plate 33 to move upward. At the same time, the ignition seat 27 moves downward under the action of the first spring 29's own resilience. The ignition seat 27 drives the igniter 28 and one end of the connecting rod 32 to move downward. At the same time, the other end of the connecting rod 32 is tightly fitted with the bottom end of the lower pressure plate 33. When the igniter 28 is completely inside the receiving groove 26, the connecting rod 32 is in a horizontal state. Retracting the igniter 28 can prevent it from being burned by flames for a long time, thereby increasing its service life. When the user needs to perform maintenance, the user first removes the bolts between the closing plate 5 and the mounting plate 3, and then the user controls the motor 10 to work.The output end of the motor 10 drives the threaded rod 11 to rotate, and the rotating threaded rod 11 can make the receiving threaded sleeve 12 and drive the stabilizing block 6, the closing plate 5, the second pipe 14 and the fourth pipe 19 to move to the side away from the furnace body 1. At this time, the stabilizing block 6 slides on the top of the sliding rod 7, and the stability of the movement of the closing plate 5, the second pipe 14 and the fourth pipe 19 is improved by the stabilizing block 6 and the sliding rod 7. When the receiving threaded sleeve 12 and the closing plate 5 move to one side of the motor 10, the user controls the movement of the push plate 8 through the first electric push rod 9, so that the bottom end of the latch 13 is no longer inside the receiving threaded sleeve 12. At this time, the user can remove the closing plate 5, the second pipe 14 and the fourth pipe 19, so as to facilitate the user to inspect and maintain the third pipe 18, the first pipe 20 and the refractory base 25. After the user completes the inspection and maintenance, Put it into the top of the bracket 4 so that the slide bar 7 is inside the stabilizing block 6, and the receiving threaded sleeve 12 is also inside the buckle groove at the bottom end of the stabilizing block 6. Then the user inserts the pin 13 into the receiving threaded sleeve 12 through the first electric push rod 9 to complete the limit work. The user resets the closing plate 5, the second pipe 14 and the fourth pipe 19 through the motor 10 and the threaded rod 11, and finally tightens it with bolts. This device is not only convenient for users to carry out inspection and maintenance work, but also can quickly cut off the air or fuel, thereby improving its safety of use. At the same time, this device can also ensure that the fuel is sprayed and burned in all directions without dead ends, avoiding local high temperature inside the furnace body 1, thereby improving the fuel effect and product yield, and at the same time can effectively reduce fuel consumption, thereby achieving the effect of energy saving, consumption reduction, cost reduction and efficiency improvement.
