[0015] The following is in conjunction with the appendix Figure 1-5 The present invention will be further described below.

[0016] To address the problems existing in the background technology, this application proposes the following technical solution: an electronic firework controlled by a drone, comprising a mounting frame 1 and an adjustment frame 9. Multiple sets of first ejector pipes 12 are externally fixedly connected to the adjustment frame 9. One end of each first ejector pipe 12 is detachably connected to a second ejector pipe 13. A gas release component is provided at the bottom of the adjustment frame 9. An igniter is fixedly connected inside each first ejector pipe 12. An angle adjustment component is provided between the mounting frame 1 and the adjustment frame 9. The mounting frame 1, as the core connection between the electronic firework and the drone, is made of lightweight and high-strength alloy material. It can withstand the weight of components such as the adjustment frame 9 and ejector pipes without excessively increasing the drone's load, ensuring stable takeoff of the drone and avoiding the problem of shortened drone flight time or unstable flight caused by excessive weight in traditional firework devices. The adjustment frame 9 works in conjunction with the mounting frame 1 to provide stable support for the first ejector pipe 12. The distribution of multiple sets of first ejector pipes 12 is precisely set, and they can be arranged in various shapes such as rings and fan shapes according to the performance requirements, so as to achieve multi-directional and multi-angle firework spraying effects, break through the limitation of the single spraying direction of traditional ground firework, and enhance the visual layering of aerial performances.

[0017] The detachable connection between the first ejector pipe 12 and the second ejector pipe 13 is key to meeting the needs of different performance scenarios: when a close-range, concentrated firework effect is required, the first ejector pipe 12 can be used alone; when it is necessary to expand the spray range or increase the height of the fireworks, the second ejector pipe 13 can be added to extend the overall length without replacing the entire device, greatly improving the flexibility and versatility of the equipment. The gas release component at the bottom of the adjustment frame 9 provides a stable power source for the fireworks spray, replacing the flammable and explosive risks of traditional gunpowder fireworks. Controllable gas release ensures safe ignition, making it especially suitable for performances near densely populated areas or flammable and explosive locations.

[0018] The igniter inside the first ejector pipe 12 works directly with the gas release component to achieve a continuous "gas delivery-ignition-jet" action. The ignition timing is precise and controllable, avoiding the problems of delayed or accidental ignition in traditional gunpowder fireworks, ensuring that each jet is precisely in sync with the performance rhythm. The angle adjustment component between the mounting frame 1 and the adjustment frame 9 breaks through the limitations of the fixed angle of traditional fireworks: by adjusting the tilt angle of the adjustment frame 9, the first ejector pipe 12 and the second ejector pipe 13 can be oriented in different directions. Combined with the aerial movement of the drone, a dynamic fireworks trajectory can be formed in the air.

[0019] In this embodiment, the gas release assembly includes a combustible gas storage tank and an oxygen storage tank 10 fixedly connected to the bottom of the adjusting frame 9. Multiple sets of delivery pipes are fixedly connected to both the combustible gas storage tank 11 and the oxygen storage tank 10. Each delivery pipe is fixedly connected to a corresponding first ejection pipe 12, and a solenoid valve is fixedly connected to each delivery pipe. A controller is fixedly connected to the outside of the adjusting frame 9. The solenoid valve and the igniter are electrically coupled to the controller. The combustible gas storage tank and the oxygen storage tank 10 in the gas release assembly are made of corrosion-resistant, high-strength sealing material, capable of stably storing combustible gas and oxygen respectively. Furthermore, their independent design avoids gas mixing and potential safety hazards, significantly improving safety compared to the single fuel storage of traditional gunpowder fireworks. Both storage tanks are equipped with pressure monitoring devices (integrated into the controller system), which can monitor the gas pressure inside the tank in real time. When the gas pressure is too low, the controller promptly issues a warning to prevent insufficient gas from weakening or interrupting the fireworks' spray effect, ensuring the continuity of the performance.

[0020] Multiple sets of delivery pipes correspond one-to-one with the first ejector pipe 12, using high-temperature resistant and leak-proof metal pipes to ensure a stable supply of gas and oxygen to each ejector pipe, preventing gas leaks due to pipe aging or damage, thus further ensuring safety. The solenoid valves in the delivery pipes act as "switches" for gas delivery, precisely controlled by a controller: during performances, the controller adjusts the opening duration and interval of the solenoid valves according to a preset program or remote command, thereby regulating the mixing ratio and delivery volume of gas and oxygen—different mixing ratios can produce different colors and heights of fireworks effects (e.g., increasing the oxygen ratio makes the flames stronger and the fireworks shoot higher), meeting diverse performance needs and avoiding the limitations of traditional gunpowder fireworks effects being fixed and unadjustable.

[0021] As the "central hub" of the entire gas release and ignition system, the controller not only synchronously controls the actions of the solenoid valve and igniter to ensure immediate ignition after gas delivery and prevent gas accumulation that could lead to risks, but also supports remote wireless connectivity (such as connection to a drone remote controller or a dedicated control terminal). Operators can adjust injection parameters in real time from a safe area without close-range operation, further enhancing safety. Simultaneously, the controller has a self-diagnostic function; if the solenoid valve or igniter malfunctions, it can promptly cut off the gas supply and issue an alarm, preventing equipment failures from causing safety accidents and making the use of electronic fireworks more reliable and worry-free.

[0022] In this embodiment, a rotating rod 5 is rotatably connected to the outside of the mounting frame 1, and an adjusting frame 9 is fixedly connected to the rotating rod 5. Gears 6 are fixedly connected to both ends of the rotating rod 5, and a rack 7 is meshed with the outside of the gears 6. The angle adjustment assembly includes a motor 2 fixedly connected to the outside of the mounting frame 1 and a threaded rod 3 fixedly connected to the output end of the motor 2. A nut is threadedly connected to the outside of the threaded rod 3, and a sliding frame 8 is fixedly connected to the outside of the nut. A guide rod 4 is fixedly connected to the outside of the mounting frame 1, and the guide rod 4 passes through the sliding frame 8. The rotating rod 5 outside the mounting frame 1 is made of high-strength metal, and a precision bearing is provided at the rotatable connection point with the mounting frame 1 to ensure smooth and uninterrupted rotation of the rotating rod 5, avoiding inaccurate angle adjustment due to excessive rotational resistance. The adjustment frame 9 is fixedly connected to the rotating rod 5, which means that the rotation of the rotating rod 5 can directly drive the adjustment frame 9 to rotate synchronously, thereby changing the angle of the first ejector pipe 12 and the second ejector pipe 13. The transmission efficiency is high and the angle adjustment range is wide (it can achieve adjustment from 0-90° or even a larger range). Compared with the traditional manually adjustable fireworks device, it not only saves manpower, but also achieves precise angle control, meeting the high requirements of aerial performance for angle accuracy.

[0023] The gears 6 at both ends of the rotating rod 5 mesh with the rack 7, forming a stable transmission structure. This meshing transmission of gears 6 and rack 7 offers advantages such as a fixed transmission ratio and precise angle adjustment, avoiding the problems of large angle deviations and easy loosening inherent in traditional linkage adjustment methods. This ensures that the adjustment frame 9 accurately stops at the preset angle with each rotation, preventing angle deviation due to drone flight vibrations and guaranteeing the stability of the fireworks spray direction. The motor 2 in the angle adjustment assembly serves as the power source, employing a small, high-torque motor 2. While providing sufficient power, it is lightweight and energy-efficient, avoiding excessive load on the drone and ensuring its endurance and flight stability.

[0024] The threaded rod 3 at the output end of motor 2 engages with the nut, converting the rotational motion of motor 2 into the linear motion of the nut: when motor 2 rotates, the threaded rod 3 drives the nut to move axially along the threaded rod 3, thereby pushing the sliding frame 8 to move synchronously. The guide rod 4 on the outside of the mounting bracket 1 passes through the sliding frame 8, providing precise guidance for the movement of the sliding frame 8, preventing the sliding frame 8 from deviating or wobbling during movement, ensuring that the rack 7 can slide smoothly and drive the gear 6 to rotate precisely, further improving the accuracy of angle adjustment.

[0025] In this embodiment, the first ejector pipe 12 and the second ejector pipe 13 are provided with multiple sets of positioning grooves 14 on their exteriors. Positioning plates 17 are provided within the positioning grooves 14. External threads 16 are provided on the exteriors of the positioning plates 17, the first ejector pipe 12, and the second ejector pipe 13. A threaded sleeve 19 is connected to the external thread of the external thread 16. A positioning post 18 is fixedly connected to the bottom of the positioning plate 17, and positioning holes 15 are provided within the positioning grooves 14. The positioning grooves 14 on the outside of the first and second nozzles 12 and 13 ensure that the positioning plate 17 can be accurately inserted into the positioning grooves 14 of the two nozzles, achieving initial alignment of the two nozzles. The positioning post 18 at the bottom of the positioning plate 17 cooperates with the positioning hole 15 in the positioning groove 14 to form a "post-hole" positioning structure: when the positioning plate 17 is inserted into the positioning groove 14, the positioning post 18 is precisely inserted into the positioning hole 15, which can effectively prevent relative rotation between the first and second nozzles 12 and 13 during the connection process, ensuring that the axes of the two nozzles are completely coincident, avoiding poor gas delivery or deviation of the firework spray direction due to misalignment, and ensuring the stability of the spray effect.

[0026] The external threads 16 of the positioning plate 17, the first ejector pipe 12, and the second ejector pipe 13 are of the same specification, ensuring that the threaded sleeve 19 can be smoothly screwed in and simultaneously cover the external threads 16 of the three parts, achieving a tight connection between them. The threaded sleeve 19 is made of high-strength wear-resistant material, and its inner wall thread has high precision. After tightening, it can generate sufficient preload force to ensure that the first ejector pipe 12 and the second ejector pipe 13 fit tightly, preventing gas leakage from the connection gap and ensuring safe use. At the same time, the detachable design of the threaded sleeve 19 makes the installation and removal of the second ejector pipe 13 convenient: when it is necessary to extend the ejector pipe, simply insert the positioning plate 17 into the positioning groove 14, insert the positioning pin 18 into the positioning hole 15, and then tighten the threaded sleeve 19; when it is not necessary to extend, simply unscrew the threaded sleeve 19 in the opposite direction to remove the second ejector pipe 13. The whole process does not require special tools, and the operation is simple and quick. Compared with traditional flange connections or welding connections, it not only saves time but also avoids component damage caused by welding, extending the service life of the equipment.

[0027] The design of multiple positioning slots 14 and positioning plates 17 can also increase the number of second ejector pipes 13 as needed (such as continuing to connect a third ejector pipe to the other end of the second ejector pipe 13), further extending the overall spray length to meet the needs of different scenarios for the height or range of firework spray, making electronic fireworks more adaptable and able to meet various performance needs from small celebrations to large-scale performances.

[0028] The usage method of this embodiment is as follows: In use, the mounting frame 1 is connected to the drone. The drone takes off and lifts the device into the air. The motor 2 is started to drive the threaded rod 3 to rotate. The threaded rod 3 pushes the sliding frame 8 to slide through the nut. The sliding frame 8 drives the rack 7 to slide. The rack 7 drives the gear 6 to rotate. The gear 6 drives the adjustment frame 9 to rotate, thereby allowing the angle of the first nozzle 12 and the second nozzle 13 to be adjusted. Subsequently, the solenoid valve in the delivery pipe is opened by the controller to allow combustible gas and oxygen to enter the first ejector pipe 12. Alternatively, a metering valve can be installed in the delivery pipe to measure the amount of combustible gas and oxygen delivered. After the delivery is completed, the ignition is performed by an igniter to complete the explosion, which will spray the paper firework in the first ejection pipe 12. In addition, in practice, if it is necessary to extend the length of the first ejector pipe 12, simply make the second ejector pipe 13 correspond to the first ejector pipe 12, then snap the positioning plate 17 into the positioning groove 14, and then rotate the threaded sleeve 19 so that the threaded sleeve 19 abuts against the outside of the positioning plate 17 to extend the connection between the first ejector pipe 12 and the second ejector pipe 13.
