The compressed air delivery unit delivers compressed air to the injection port 50. The fuel delivery unit connects to the injection port 50 and delivers fuel to the injection port 50. The compressed air and fuel mix and are sprayed out at the injection port 50. The flame formed at the nozzle 20 can ignite the mixture of compressed air and fuel at the injection port 50, producing a stage effect similar to an artillery explosion.

[0034] The special effects flame-spraying device of this application embodiment can spray fuel and compressed air together and ignite them through the flame formed by the nozzle 20, thus achieving the purpose of creating a variety of effects with one device.

[0035] Specifically, the flame at the nozzle 20 and the distance between it and the injection port 50 generally satisfy the following conditions: the horizontal distance between the nozzle 20 and the injection port 50 is 10cm to 50cm. The horizontal distance refers to the interval between the two on the same horizontal plane. Furthermore, in this embodiment, the flame height ejected from the nozzle 20 is 3m to 10m, and the height of the mixture ejected from the injection port 50 is 5m to 15m.

[0036] In some embodiments, the compressed air delivery unit includes an air compressor 41, a pressure tank 43, and a first injection valve 44. The pressure tank 43 is connected to the air compressor 41, and the first injection valve 44 is disposed on the pipeline between the pressure tank 43 and the injection port 50 to control the pressure tank 43 to deliver compressed air to the injection port 50.

[0037] In this embodiment, the air compressor 41 fills the pressure tank 43 with compressed air. A mechanical pressure gauge 42 can be installed on the pressure tank 43 to display the pressure value inside the pressure tank 43 for easy viewing by the operator. A first injection valve 44 is installed on the pipeline between the pressure tank 43 and the injection port 50. When the first injection valve 44 is opened, the compressed air in the pressure tank 43 can be delivered to the injection port 50. When compressed air is not needed, the first injection valve 44 is closed. A one-way valve can be installed between the air compressor 41 and the pressure tank 43 to ensure that compressed air does not backflow.

[0038] In some embodiments, the compressed air delivery unit includes a safety valve 45 and an exhaust port 46. The safety valve 45 is disposed on the pressure tank 43 and communicates with the exhaust port 46. In this embodiment, a safety valve 45 is configured on the pressure tank 43.

When the pressure inside the pressure tank 43 reaches a set value, the control system controls the air compressor 41 to stop operating.

[0040] In some embodiments, the special effects flamethrower includes a fuel filler valve 48, which is disposed on the connecting pipeline between the fuel delivery unit and the injection port 50. In this embodiment, when the fuel filler valve 48 is open, the fuel delivery unit supplies fuel to the injection port 50. When the injection port 50 does not require fuel, the fuel filler valve 48 is closed. The fuel delivery unit supplies fuel to the injection port 50, achieving mixing of fuel and compressed air at the injection port 50, so that they can be sprayed together from the injection port 50 when needed.

[0041] In some embodiments, the special effects flamethrower includes a consumable delivery unit 60, which is connected to a nozzle 50 to deliver the consumable material to the nozzle 50. In this embodiment, the special effects flamethrower, based on an effect similar to a cannon explosion, delivers the consumable material to the nozzle 50 via the consumable delivery unit 60, adding it to a mixture of compressed air and fuel. Upon ejection, the consumable material produces a more multi-dimensional effect.

[0042] In some embodiments, the fuel delivery unit includes a fuel tank 11, a fuel pump 12, and a second injection valve 13. The fuel pump 12 is connected to the fuel tank 11, and the second injection valve 13 is disposed on the pipeline between the fuel pump 12 and the nozzle 20 to control the delivery of fuel to the nozzle 20.

[0043] In this embodiment, the fuel pump 12 delivers fuel from the reservoir 11 to the nozzle 20 and / or injection port 50. When the second injection valve 13 is open, fuel can be delivered to the nozzle 20 and sprayed out by the nozzle 20. When the nozzle 20 does not need to spray fuel, the second injection valve 13 can be closed. The reservoir 11 can be connected to a filter 110 to filter the fuel and prevent fuel from clogging the pipeline.

[0044] Furthermore, the fuel delivery unit includes an energy storage unit 14, which is disposed between the fuel pump 12 and the second injection valve 13 to store energy. In this embodiment, the fuel pump 12 draws fuel from the fuel tank 11 and delivers it to the energy storage unit 14. The energy storage unit 14 serves to store energy, eliminate pulses, and increase injection duration.

[0045] In some embodiments, the fuel delivery unit includes a second pressure sensor 15, which is disposed on the connecting pipeline between the second injection valve 13 and the fuel pump 12. Specifically, the second pressure sensor 15 is disposed between the fuel pump 12 and the accumulator 14. The second pressure sensor 15 can detect the pressure in the pipeline in real time, and when the pressure reaches a set value, it controls the fuel pump 12 to stop operating and stop delivering fuel.

[0046] In some embodiments, the fuel delivery unit includes a one-way valve 16 and a pressure relief valve 17. The one-way valve 16 is disposed between the fuel pump 12 and the second injection valve 13 to deliver fuel to the nozzle 20, and the pressure relief valve 17 is disposed between the second injection valve 13 and the fuel reservoir 11 to allow fuel to flow back into the fuel reservoir 11. In this embodiment, the one-way valve 16 ensures that fuel is delivered from the fuel pump 12 to the accumulator 14 or the nozzle 20 without backflow. When fuel delivery is not required, pressure can be released through the pressure relief valve 17 to allow fuel to flow back into the fuel reservoir 11. The one-way valve 16 and the pressure relief valve 17 ensure that a fuel transport loop is formed within the fuel delivery unit.
