[0014] Fig. 1 is a three-dimensional structure schematic view of the utility model;

[0015] Fig. 2 is a sectional view of the spraying device;

[0017] In order to make the technical personnel in the art better understand the technical scheme of the utility model, the utility model will be further described in detail below in combination with the drawings and specific embodiments.

[0018] As Figs. 1 to 3 shown is a continuous spraying cold-flame firework machine, which comprises a feeding pipe 1, a feeding device 2 for feeding cold-flame material into the feeding pipe 1, a pushing device 3 for pushing the cold-flame material in the feeding pipe 1 forward, a heating system 4 for heating and igniting the cold-flame material in the feeding pipe 1, and a spraying device 5 for spraying the heated and ignited cold-flame material out. The general working principle is that the cold-flame material provided by the feeding device 2 is heated and ignited by the heating system, and then sprayed out of the cold-flame firework through the spraying device 5.

[0019] Spraying device:

[0020] The spraying device 5 is responsible for spraying the cold-flame material out. It includes a spray pipe 51, the front end of which is provided with a spray port 512, through which the cold-flame material is sprayed out to form the expected visual effect.

[0021] The tail end (lower end) of the spray pipe 51 is connected to a fan 6 and a gas supply device 7, which work together to achieve the spraying and burning of the cold-flame firework. The gas supply device 7 is responsible for providing compressed gas as the power source for the spraying of the cold-flame firework. High-pressure gas enters the spray pipe 51 through a pipe to spray the cold-flame material at high speed. At the same time, the fan 6 is also connected to the tail of the spray pipe 51, which functions to optimize the shape and stability of the sprayed flame by blowing in the right amount of air. The airflow generated by the fan 6 can adjust the oxygen supply of the flame, control the diffusion range of the flame, and help disperse the smoke and particulate matter generated by combustion, thereby presenting a clearer and more magnificent cold-flame firework effect and improving air quality.

[0022] A cold-flame interface 511 is provided on the side wall of the spray pipe 51, and the feeding pipe 1 is connected at the cold-flame interface 511 to send the cold-flame material into the spray pipe 51.

[0023] Gas supply device:

[0024] In order to achieve continuous spraying of the cold-flame firework, the present embodiment adopts a double-compressed gas supply system design, effectively solving the problem of spraying interruption caused by insufficient gas supply from a single gas source in the prior art. The gas supply device 7 includes at least two, in this embodiment two, compressed gas supply systems 71 capable of supplying compressed gas alternately. Each compressed gas supply system 71 includes an air charging device (for example, first air charging device 7a and second air charging device 7c, which is usually a gas pump) and a gas tank (for example, first gas tank 7b and second gas tank 7d) connected thereto. The output pipes of the first gas tank 7b and the second gas tank 7d are both connected to the same gas distribution valve 72. The gas distribution valve 72 functions to control the gas flow from the two gas tanks and guide it into the spray pipe 51.

[0025] When one gas tank is supplying gas, the other tank can be filled or other operations. By switching the gas distribution valve 72, the two compressed gas supply systems 71 can work alternately to ensure continuous supply of compressed gas, so as to realize the uninterrupted injection of cold fireworks. The test shows that the spray interval of the spray machine of the embodiment can be as short as 3 seconds, which is about 80% shorter than the prior art, and the continuity of the injection is significantly improved. In addition, the double system design also has a backup function, so that even if one system fails, the other system can still work normally, improving the reliability and stability of the equipment.

[0026] Feeding device:

[0027] In order to improve the reliability of the feeding and reduce the failure, the feeding device 2 of the embodiment is improved. The feeding device 2 is arranged on the feeding pipe 1, which includes a feeding port 11 arranged on the side wall of the feeding pipe 1, a storage hopper 21 arranged at the feeding port 11, and a discharging valve 22 for controlling the opening and closing of the storage hopper 21.

[0028] The storage hopper 21 adopts a double-layer hopper design, which includes an upper hopper and a lower hopper. The taper of the tapered part between the upper and lower hoppers is different, so as to form a gap between them. This design can prevent material blockage and ensure smooth falling of the material. The upper hopper is detachable, which facilitates the addition of cold fireworks material. A threaded opening is provided at the top of the upper hopper, and a top cover can be connected to prevent material from spilling and contamination. The discharging valve 22 is arranged at the lower hopper, and an electromagnetic valve is preferably used, which is connected with an opening and closing plate. By controlling the opening and closing of the electromagnetic valve, the insertion and pulling out of the opening and closing plate can be accurately controlled, so as to adjust the feeding speed of the cold fireworks material.

[0029] Further, the pushing device 3 is a screw type pushing structure.

[0030] Heating system:

[0031] The heating system 4 is used to control the temperature of the cold fireworks material and ignite the cold fireworks material to achieve the best injection effect. In the embodiment, the heating system 4 includes an electromagnetic heating sleeve and a heat preservation sleeve arranged outside the feeding pipe 1. The electromagnetic heating sleeve is electrically connected with the temperature controller, which can accurately control the heating power according to the preset temperature parameters, so as to ensure that the cold fireworks material reaches the required temperature. The heat preservation sleeve can reduce heat loss and improve heating efficiency.

[0032] In order to simplify the assembly process, the embodiment preferably adopts a quick connection mode to connect the pipe interfaces, which can reduce the difficulty of assembly process and shorten the assembly time.

[0033] The continuous injection cold fireworks spray machine provided by the embodiment realizes the continuous injection of cold fireworks by adopting a double compressed gas supply system, and improves the reliability and stability of the equipment.
