[0026] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0027] like Figure 1 , Figure 2 and Figure 4 As shown, an embodiment of the present invention provides a fully premixed integrated ignition air gun, including a premixing chamber 1. A gun barrel 2 is welded to one end face of the premixing chamber 1, and a first air inlet pipe 3 is welded to the other end face of the premixing chamber 1. The first air inlet pipe 3 is connected to the premixing chamber 1. A circular hole 301 is opened on one end face of the first air inlet pipe 3. A second air inlet pipe 4 is welded inside the hole wall of the circular hole 301. The second air inlet pipe 4 passes through the pipe wall of the first air inlet pipe 3 and extends into the first air inlet pipe 3. The second air inlet pipe 4 includes a concentric tube 401, which is located inside the first air inlet pipe 3. The axis of the concentric tube 401 is the same as the axis of the first air inlet pipe 3. Air flows into the premixing chamber 1 from the first air inlet pipe 3, and gas flows into the premixing chamber 1 through the concentric tube 401.

[0028] A first mixing component 5 is fixedly connected to the inner wall of the premixing chamber 1. The first mixing component 5 enables the air and fuel gas in the premixing chamber 1 to be fully mixed. The premixing chamber 1 includes a cylindrical cavity 101 and a conical cavity 102. The conical cavity 102 is welded to the cylindrical cavity 101 and is welded to the barrel 2.

[0029] like Figure 3 and Figure 5 As shown, the first mixing component 5 includes a cylinder 501 and a pair of first supports 506. The first supports 506 are welded to the inner wall of the cylindrical cavity 101. The cylinder 501 is rotatably connected to the first supports 506. A bearing 507 is welded onto the first supports 506. The bearing 507 includes an outer ring and an inner ring. The outer ring is welded to the first supports 506, and the inner ring is welded to the cylinder 501, so that the cylinder 501 can rotate in the premixing chamber 1.

[0030] The axis of the cylinder 501 is the same as the axis of the concentric tube 401. A first helical blade 502 is welded on the outer wall of the cylinder 501. Multiple air outlets 503 are opened on the outer wall of the cylinder 501. The outer diameter of the cylinder 501 is smaller than the inner diameter of the first air inlet pipe 3. Air flows into the premixing chamber 1 from the first air inlet pipe 3. A portion of the air flows from the outside of the cylinder 501. This portion of the airflow blows onto the first helical blade 502. Since the first helical blade 502 is helical, the air can drive the cylinder 501 to rotate.

[0031] The diameter of the cylinder 501 is larger than the diameter of the concentric tube 401, and the top end of the concentric tube 401 extends into the cylinder 501. The gas flows through the concentric tube 401 and enters the cylinder 501. Under the combined action of the centrifugal force generated by the rotation of the cylinder 501 and the impact force of the gas itself, the gas rushes out of the outlet 503 and mixes thoroughly with the air outside the cylinder 501. The first spiral blade 502 rotates to further agitate the mixed gas.

[0032] A conical cap 505 is welded to the top of the cylinder 501. An air outlet 503 is also provided on the outer wall of the conical cap 505. The gas at the end of the cylinder 501 is blocked by the conical cap 505 and disperses to the surroundings through the air outlet 503, thereby mixing better with the air.

[0033] A second helical blade 504 is welded to the inner wall of the cylinder 501. As the gas diffuses outwards inside the cylinder 501, it also moves forward. The part of the gas that moves forward impacts the second helical blade 504. Since the second helical blade 504 is also helical, it can provide power for the rotation of the cylinder 501, thereby increasing the rotation speed of the cylinder 501 and making the gas mixture more uniform.

[0034] A second mixing assembly 6 is welded inside the side wall of the conical cavity 102. The second mixing assembly 6 includes a second support 601 and a propeller 602. The second support 601 is welded to the inner wall of the conical cavity 102, and the propeller 602 is rotatably connected to the second support 601. When the mixed gas encounters the propeller 602, it blows the propeller 602 to rotate, which can further mix the gas.

[0035] Multiple spiral grooves 103 are provided on the inner wall of the premixing chamber 1. The mixed gas rotates under the action of the first spiral blade 502, forming a spiral flow. The spiral grooves 103 on the inner wall of the premixing chamber 1 can make the spiral airflow smoother, thereby increasing the gas mixing.

[0036] When using, such as Figure 1 As shown, the air or oxygen intake pipe is connected to the first intake pipe 3, and the gas intake pipe is connected to the second intake pipe 4. Air flows into the premixing chamber 1 from the first intake pipe 3. The air is blown onto the first spiral blade 502, causing the cylinder 501 to rotate. The gas enters the second intake pipe 4, flows through the concentric pipe 401 and enters the cylinder 501. Due to the rotation of the cylinder 501, the gas flows out from the outlet 503 and mixes with the air. When the mixed gas flows through the second mixing component 6, it encounters the propeller 602. The propeller 602 agitates the mixed gas, making the gas fully mixed and the gas and air mixed evenly, so that the gas can be fully burned, and more heat can be generated during combustion, reducing the waste of gas.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
