[0056] The present application provides a fireworks setting device. To make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0059] In the prior art, the traditional way of setting off handheld fireworks has close-range safety hazards (such as explosion of the tube, deflection causing burns) and lacks stable control over the angle and direction of setting off, which can easily cause accidents due to operator fatigue or shaking.

[0060] Based on the above problems in the prior art, the present application provides a fireworks setting device, which includes a housing 100 , a charge assembly 200 and a power assembly 300 .

[0061] In one embodiment of the present application, Figure 4As shown, the housing 100 includes a grip portion 110 and a launching portion 120 connected to the grip portion. In another feasible embodiment of the present application, the grip portion 110 and the launching portion 120 are perpendicular to each other. An emission channel 122 is formed inside the launching portion 120. The emission channel 122 can be arranged radially within the launching portion 120. A charge end 121 and a launching end 123 are formed on both sides of the emission channel 122. Among them, the outer contour of the grip portion 110 is optimized according to the palm grasping curve, which conforms to ergonomics and is convenient for stable grasping, ensuring the comfort of operation; anti-slip ribs are distributed on the surface of the grip portion 110, which can increase the friction with the hand during grasping, and can effectively prevent the firing device from slipping off even in a humid environment, thus ensuring the safety of operation. The emission channel 122 is a single straight-line hollow inner cavity structure, and its shape and size can be specifically set according to the shape of the housing 100; the emission channel 122 provides an accurate path guidance for the launching of fireworks. Through geometric constraints and guidance mechanisms, the fireworks can only run along this straight channel, minimizing the deviation of the running direction of the fireworks caused by channel bending or irregularity, and ensuring that the fireworks will not deviate from the axis of the emission channel 122 during launching. This enables the fireworks to be launched straight towards the preset airspace with extremely high accuracy, enhancing the control ability of the fireworks launching device.

[0062] The charging assembly 200 includes a charging cartridge 210 and a locking cover 220, as Figure 3 and Figure 7As shown, the medicine loading magazine 210 matches the launching channel 122 to form a directional pulling structure, so that the medicine loading magazine 210 can be quickly and accurately positioned along the axis of the launching channel 122 during operation, and each pulling action is smooth and unobstructed, which greatly saves the time for loading fireworks and improves the use efficiency of the launching device; the shape of the medicine loading magazine 210 matches the launching channel 122, and the shape of the medicine loading magazine 210 is not unique. The cross-section of the medicine loading magazine 210 can be circular, but is not limited to this; the cross-sectional area of ​​the medicine loading magazine 210 is slightly smaller than the launching channel 122, and the friction with the inner wall of the launching channel 122 can be reduced during the pulling process, making the operation smoother, and there will be no jamming or jamming, so that the medicine loading magazine 210 can be smoothly pulled and placed inside the launching channel 122. The charge box 210 is provided with a plurality of charge slots 211 in sequence along the circumferential direction. The shapes of the plurality of charge slots 211 may be the same or different. A plurality of fireworks are sequentially loaded into the charge slots 211. The charge slots 211 are provided on the charge box 210 and are parallel to the launching channel 122, so as to ensure that the fireworks are not offset and locked before launching. In addition, the charge slots 211 can be used to place different types of fireworks. By reasonably matching different types of fireworks, different types of fireworks can be released in combination according to a preset program, so as to present a colorful firing effect when launched, and bring a better firing experience to the user.

[0063] Furthermore, in the above embodiment, if Figure 5 and Figure 6 As shown, the medicine loading box 210 includes an axis 212 and a plurality of medicine loading slots 211 .

[0064] The axis 212 is precisely coaxially arranged based on the radial axis 212 of the launch channel 122. When the lock cover 220 is closed, one end of the axis 212 is correspondingly engaged with the lock cover 220, and the other end of the axis 212 is connected to the launch end, ensuring that the charge box 210 still maintains zero offset positioning when it is subjected to radial fireworks gas impact force and axial recoil force in the launch channel at the same time, avoiding axial movement or radial deflection of the charge box due to vibration. This embodiment significantly improves the impact resistance and adaptability of the charge assembly 200 through the optimization of the mechanical transmission path and the coordination of dynamic sealing, and ensures the repeated positioning accuracy of the axis 212 holding structure during rapid disassembly and assembly.

[0065] The charge grooves 211 are distributed circumferentially with the axis 212 as the center. Figure 6As shown, the axis line of each of the charging grooves 211 is parallel to the axis 212 and the radial axis line of the launching channel 122, and the notch of the charging groove 211 is arranged on the circumference of the charging box 210. At the same time, considering the stability of the fireworks after filling, the width of the notch is designed to be smaller than the diameter of the fireworks, which can not only prevent the fireworks from falling out due to shaking during transportation, operation and other links, but also provide a proper restraint environment for the fireworks, ensuring the stable performance of the overall performance of the launching device; through the step-by-step rotation of the axis 212, the openings of each of the charging grooves 211 are aligned with the transmission assembly 311 in the power assembly 300 in turn, and a single loading can realize the automatic sequential switching and launching of multiple types of fireworks, forming a dynamically changing combined firing effect, which significantly improves the richness of the performance. When the target charging slot 211 is aligned with the conveying assembly 311, the fireworks rely on their own gravity to slightly press against the conveying assembly 311 through the notch of the charging slot 211, so that the fireworks and the conveying assembly 311 are tightly and gently connected with just the right pressure; then the conveying assembly 311 is started, and the friction between the conveying assembly 311 and the fireworks is used to push the fireworks to the launching end 123. This arrangement ensures that sufficient friction can be generated between the two, and avoids damage to the fireworks due to excessive pressure. When the device is in operation, due to the circumferential layout of the charging slots 211, the charging slots 211 that are not aligned with the conveying assembly 311 are shielded. This means that, from a physical structure level, except for the charging slots 211 that are currently connected to the pushing path and can participate in the fireworks launching process, the fireworks in the remaining charging slots 211 are in a physically isolated state, avoiding collisions, electrostatic discharges or other triggering sources, eliminating the risk of mis-triggering or chain ignition, and providing a rock-solid guarantee for the safe and stable operation of the fireworks launching device.

[0066] In one embodiment of the present application, Figure 3 , Figure 10 and Figure 11 As shown, the locking cover 220 is arranged at the charging end 121 and closes the launching part 120 in a hinged manner, ensuring that the charging magazine 210 is rigidly fixed in the launching channel 122. When the charging magazine 210 is subjected to axial recoil or vibration in the launching channel 122, it still remains fixed with zero displacement, avoiding the risk of the charging magazine shifting or slipping due to impact; the inner side of the locking cover 220 fits tightly with the launching channel 122, forming an airtight space in the closed state, which not only blocks external moisture and dust from invading the launching channel, but also improves the safety of the operating environment.

[0067] Furthermore, in the above embodiment, the locking cover 220 includes a sealing cover 221, a knob 222 and a fixing spring 225. Figure 5 shown.

[0068] In another feasible embodiment of the present application, the sealing cover 221 disposed at the charge end 121 can also be clamped and connected to the launching part 120, and is clamped and engaged with the end of the axis 212 in the closed state to form a rigid torque transmission path; after the loading is completed, the sealing cover 221 is closely attached to the charge end 121 to achieve pressure sealing, forming a reliable sealing structure. This kind of sealing can not only prevent the reverse impact force generated during the fireworks launching process, ensure the effective utilization of the launching power, but also avoid external dust, sundries, etc. from entering the inside of the launching part 120 and damaging the device, thereby prolonging the service life of the device and improving the stability and reliability of the device. The knob 222 is disposed at the geometric center of the sealing cover 221 and corresponds to the axis 212. After closing the sealing cover 221, the knob 222 is clamped with the axis 212 to form a mechanical interlocking system. By rotating the knob 222, the axis 212 is driven to drive the charge magazine 210 corresponding to the conveying assembly 311 to be positioned. This corresponding relationship ensures that an accurate fit can be achieved between the knob 222 and the axis 212. When the sealing cover 221 is closed, the knob 222 will be closely clamped with the axis 212 to form a stable connection. This clamping method is like a key inserted into a lock core, enabling the rotation of the knob 222 to be directly transmitted to the axis 212 to achieve synchronous movement of the two. By rotating the knob 222, the user can easily control the rotation of the axis 212. Since a plurality of the charge grooves 211 are sequentially arranged along the periphery of the charge magazine 210, and the rotation of the axis drives the entire charge magazine 210 to rotate. Therefore, as the knob 222 rotates, different charge grooves 211 will sequentially rotate to positions corresponding to the conveying assembly 311. In this way, the user can flexibly select the types and sequences of the fireworks to be launched according to their own needs. The design and cooperation of the sealing cover 221 and the knob 222 make the fireworks launching device more convenient and efficient in operation, more rich and diverse in functions, bringing a more excellent user experience and a more magnificent fireworks viewing effect to the user.

[0069] Specifically, such as Figure 7As shown, the axis 212 is connected to the sealing cover 221 through a polygonal coupling 226. Optionally, the polygonal coupling 226 is hexagonal. The polygonal coupling 226 is disposed between the charging groove 211 and the sealing cover 221 and is located at the position of the axis 212. Specifically, the polygonal coupling 226 is engaged with the charging groove 211 through the corresponding hole of the charging groove 211 on the axis 212. The multiple planes of the polygonal coupling 226 are evenly distributed, forming a full circumferential rigid contact with the corresponding holes on the charging groove 211. The geometric characteristics of the polygon can provide higher torsional stiffness, avoiding slipping or idling caused by uneven force during knob operation (especially in high-torque scenarios). The polygonal coupling 226 corresponds to the charging groove 211 and the limiting groove 224. Through the polygonal coupling 226, the charging groove 211 and the limiting groove 224 work together to ensure the accurate alignment of the charging groove 211 and the conveying assembly 311. In addition, the cooperation between the polygonal coupling 226 and the sealing cover does not require strict angle calibration. When closing, it is automatically guided to the correct position through the progressive engagement of multiple planes, simplifying the assembly process.

[0070] The fixing spring 225 is sleeved on the rotating shaft of the knob 222 and is disposed between the knob 222 and the axis 212 to fix the charging cartridge 210 after closing the sealing cover 221.

[0071] As Figure 7 shown, one end of the fixing spring 225 abuts against the locking cover 220, and the other end of the fixing spring 225 abuts against the polygonal coupling 226. The fixing spring 225 can absorb impact energy, reduce the direct collision between components, and avoid damage. The fixing spring 225 can maintain stable performance for a long time, repeatedly undergoing elastic deformation and recovery without obvious fatigue or damage.

[0072] Furthermore, in the above embodiment, as Figure 8 and Figure 9As shown, a plurality of limiting grooves 224 are provided on the knob 222 in the circumferential direction. The limiting grooves 224 are arranged in one-to-one correspondence with the charging grooves 211. A limiting member 223 is provided at the charging end 121 corresponding to the limiting grooves 224. When the user rotates the knob 222, the limiting member 223 will rotate together with the knob 222 until it is engaged with one of the limiting grooves 224, so as to ensure that one of the charging grooves 211 corresponding to the limiting groove 224 is arranged at the position corresponding to the conveying assembly 311. The arrangement of the limiting member 223 and the limiting groove 224 ensures the fixation of the charging cartridge 210 after rotating the knob 222, and ensures that only one of the charging grooves 211 is accurately arranged at the position corresponding to the conveying assembly 311. When one of the charging grooves 211 exactly aligns with the conveying assembly 311, the limiting member 223 will quickly embed into the limiting groove 224 to the corresponding position, firmly fixing the charging cartridge 210 in the current position. This fixing method can effectively prevent the charging cartridge 210 from accidentally rotating due to factors such as vibration and impact force during the fireworks launching process.

[0073] The limiting member 223 further includes an elastic member 227. The elastic member 227 provides elastic force for the limiting member 223 to ensure that the limiting member 223 is engaged with the limiting groove 224 when the knob 222 rotates to a position where one of the limiting grooves 224 corresponds to the limiting member 223.

[0074] Specifically, the elastic member 227 is a spring. As Figure 7 shown, in the case of frequent operation or vibration, the device will generate a large impact, resulting in accelerated wear and even damage to the limiting groove 224 or the limiting member 223. The elasticity of the elastic member 227 can buffer the impact force when rotating in place, reduce metal fatigue and wear, and extend the service life of the limiting groove 224 or the limiting member 223. The elastic member 227 may provide better adaptability. The size of the limiting groove 224 may change due to manufacturing errors or long-term use and wear. The elasticity of the elastic member 227 can compensate for this change to ensure that the limiting member 223 can still reliably snap into the hole and maintain the stability of fixation. The limiting member 223 may not fit tightly after the hole is worn, resulting in loose fixation. When the limiting member 223 is spring-loaded, the spring will be compressed when entering the limiting groove, providing a continuous pressing force while allowing a certain amount of elastic deformation. The elastic member 227 may make the operation smoother. When the user rotates the knob 222, the limiting member 223 can more easily slide into the limiting groove 224 under the action of the elastic member 227, reducing the sense of jamming. Especially in the case of frequent rotation adjustment, the elastic feedback of the elastic member 227 may improve the user experience, making the rotation process smoother while still maintaining the accuracy of positioning.

[0075] The presence of the limiting member 223 and the limiting groove 224 greatly improves the accuracy and reliability of fireworks launching. During the launching of fireworks, the stable cartridge 210 can ensure that the fireworks are accurately placed on the conveying assembly 311. The conveying assembly 311 has a stable conveying function and can ensure that the fireworks are smoothly pushed to the launching end 123 and launched according to a predetermined trajectory and sequence. Without the fixation of the limiting member 223 and the limiting groove 224, the cartridge 210 may be displaced instantaneously during launching, resulting in a position offset between the charging groove 211 and the conveying assembly 311, making it impossible for the fireworks to be loaded and launched normally, and affecting the effect and rhythm of the entire fireworks display. Moreover, the limiting member 223 and the limiting groove 224 also make the operation of the device more convenient and efficient. The user only needs to turn the knob 222 to a suitable position, and the limiting member 223 and the limiting groove 224 will automatically complete the clamping and fixation, without additional complex operations to ensure the stable position of the cartridge 210. This not only saves time but also reduces the operation difficulty. Even a person who uses the device for the first time can easily get started and quickly achieve the orderly launching of different types of fireworks, adding more excitement and fun to the fireworks show.

[0076] Further, in another embodiment of the present application, as Figure 6 shown, through the phased power transmission and precise control design of the power assembly 300, the efficient coordination of the fireworks pushing and launching actions is achieved. The power assembly 300 includes a first power part 310 arranged on one side of the launching channel 122 and a second power part 320 arranged at the launching end 123. The power assembly 300 further includes a power switch 330. Among them, the two power parts cooperate with each other through a clever power distribution and transmission mechanism to provide precise power support for different movement stages of the fireworks. The first power part 310 includes the conveying assembly 311 corresponding to the charging groove 211. The conveying assembly 311 is made of a composite material with high temperature resistance and antistatic properties, which can effectively ensure the safety of the fireworks during the pushing process. The conveying assembly 311 is arranged parallel to the axis of the charging groove 211 to ensure that the fireworks always move linearly along the radial direction of the launching channel 122 during the pushing process, avoiding deflection or tilting.

[0077] In another embodiment of the present application, the power assembly 300 includes the power switch 330. The power switch 330 is respectively connected to the battery 600, the first power part 310, and the second power part 320. The power switch 330 is used to control the conduction and cut-off of the circuit.

[0078] In a feasible embodiment of the present application, the fireworks launching device further includes indicator lights located on both sides of the cartridge 210.

[0079] When the power switch 330 is turned on, the fireworks launching device enters the working mode, and the indicator lights on both sides of the cartridge 210 will light up immediately. The indicator lights have dual functions: First, the indicator lights play a decorative role on the one hand, enriching the experience of launching fireworks; Second, the indicator lights can be used to indicate whether the fireworks launching device is in the working mode.

[0080] Further, in the above embodiment, the second power unit 320 includes a first flywheel 321, a second flywheel 322, a second motor 323, a third motor 324, and a second switch 325.

[0081] As Figure 8 shown, the first flywheel 321 and the second flywheel 322 are fixedly arranged side by side inside the launching end 123. The connecting line of the centers of the first flywheel 321 and the second flywheel 322 is perpendicular to the launching channel 122. The two flywheels rotate synchronously, and there is a certain gap between the first flywheel 321 and the second flywheel 322. This gap allows the fireworks to pass through smoothly, neither causing jams when the fireworks pass through nor resulting in poor acceleration due to too large pores. The first flywheel 321 and the second flywheel 322 rotate in opposite directions respectively, and an acceleration channel 326 is formed between the first flywheel 321 and the second flywheel 322. As Figure 8 shown, the acceleration channel 326 corresponds to the conveying assembly 311. The fireworks pushed by the conveying assembly 311 reach the launching end 123 and enter the acceleration channel 326 for launching. After the conveying assembly 311 pushes the fireworks to the launching end 123, the fireworks leave the conveying assembly 311 and pass through the first flywheel 321 and the second flywheel 322. Under the action of the strong frictional force and clamping force generated by the high-speed rotation of the flywheels, the fireworks obtain a significant acceleration. This acceleration mechanism provided by the flywheels greatly improves the initial velocity of the fireworks compared with the traditional single-push launching method. Due to the significant increase in the initial velocity, the fireworks shot out at high speed can overcome more air resistance and gravity effects, thus achieving a farther shooting range.

[0082] Specifically, as Figure 6 and 8 shown, the second motor 323 is connected to the first flywheel 321, and the third motor 324 is connected to the second flywheel 322, so that the power output of the motor can directly and effectively drive the rotation of the flywheels to drive the relative rotation of the first flywheel 321 and the second flywheel 322. The second switch 325 is connected to the second motor 323 and the third motor 324. After pressing the second switch 325, the second motor 323 and the third motor 324 are started, and the fireworks in the launching channel 122 are shot out.

[0083] Furthermore, the surfaces of the first flywheel 321 and the second flywheel 322 are covered with a flexible protective ring, which is evenly and seamlessly attached to the surfaces of the first flywheel 321 and the second flywheel 322. The flexible protective ring is tightly and firmly combined with the flywheel. Whether under the strong centrifugal force generated when the flywheel rotates at high speed or in the friction and collision process when in contact with fireworks, the flexible protective ring can be firmly fixed in place without loosening or falling off, ensuring the stable function of its function. In addition, the flexible protective ring plays a vital dual role. On the one hand, the flexible protective ring ensures the friction between the first flywheel 321 and the second flywheel 322 and the fireworks. During the rotation of the flywheel, the contact area with the surface of the fireworks is increased, so that the fireworks provide a strong driving force for the fireworks, so that they can obtain sufficient acceleration in the acceleration channel 326 and smoothly shoot out from the launch end 123. On the other hand, the flexible protective ring can effectively avoid squeezing the fireworks. The structure of fireworks is relatively fragile. When they are directly in contact with the hard flywheel and squeezed, the internal structure of the fireworks may be destroyed, affecting the firing effect or causing danger. The flexible protective ring has good elasticity and buffering performance. When the flywheel clamps the fireworks, it can absorb and disperse part of the pressure, just like a soft cushion, evenly distributing the pressure on the surface of the fireworks to avoid excessive local pressure. This design greatly improves the success rate and safety of fireworks launch. Since the fireworks are well protected during the launch process, the risk of damage due to squeezing is avoided, so that each firework can be launched in the best condition, which significantly improves the effect of fireworks. At the same time, it also reduces the potential safety hazards caused by damage to fireworks, providing users with a more reliable and reassuring experience.

[0084] Furthermore, in the above embodiment, if Figure 6 As shown, the first power unit includes the transmission component 311 , a first motor 312 and a first switch 313 .

[0085] like Figure 5 and Figure 6 As shown, the first switch is arranged on the handle 110, and the first motor 312 is fixed inside the handle 110, which not only provides reliable support for the first motor 312, allowing it to remain stable during operation and reduce the loss and failure risk caused by shaking or vibration, but also makes full use of the internal space of the handle 110, making the structure of the entire firework launching device more compact and reasonable, achieving an efficient layout in a limited space, and improving the overall aesthetics and practicality of the device. The first motor 312 is arranged below the transmission component 311. In another feasible embodiment of the present application, as Figure 8As shown, the conveying component 311 is a conveyor belt, and a certain gap is reserved between the conveying component 311 and the first motor 312. The first switch 313 is electrically connected to the first motor 312. The first motor 312 drives the conveying component 311 to perform an axial propulsion movement through a worm and worm gear transmission member 500. Among them, the worm 501 is the driving member and is coaxially connected to the first motor 312, and the worm gear 502 is the driven member. The worm gear 502 is meshed and connected to the conveying component 311, and their axes are orthogonally distributed in space. Through the transmission mode of the worm 501, the high-speed and low-torque movement of the motor can be converted into the low-speed and high-torque movement of the worm gear 502, and a 90-degree vector conversion of the rotation direction is realized to drive the conveying component 311, achieving stable and noiseless transmission. Through such a design, the power of the first motor 312 is continuously transmitted to the conveying component 311, ensuring the power supply of the conveying component 311. When the first motor 312 is started, the motor shaft drives the gear to rotate, and the gear meshes with the transmission component of the conveying component 311, realizing efficient power transmission, ensuring that the conveying component 311 can operate stably and smoothly, providing a solid power guarantee for the pushing of fireworks, so that the fireworks can be accurately conveyed to the launching end 123 according to the preset rhythm and speed.

[0086] The first switch 313 is electrically connected to the first motor 312. After pressing the first switch 313, the first motor 312 starts, and the power generated by it drives the conveying component 311 to start transmission through the meshing action of the gears. The power generated by the first motor 312 is transmitted to the conveying component 311 smoothly and precisely, enabling the conveying component 311 to operate stably at a predetermined speed and direction, providing stable and reliable power support for the conveying of fireworks, and ensuring that the fireworks can be accurately transmitted to the predetermined position.

[0087] Specifically, when the user presses the first switch 313, the first motor 312 starts quickly and begins to run at high speed. Driven by the first motor 312, the conveying component 311 immediately starts to move. The conveying component 311 is connected to the first motor 312. Driven by the first motor 312, the conveying component 311 moves towards the launching end 123 to push the fireworks in the charging groove 211 to the launching end 123 without squeezing the fireworks, which can not only provide enough friction to push the fireworks forward but also avoid damaging the fireworks, ensuring that each firework can reach the launching position intact.

[0088] Furthermore, in the above embodiment, a safety device 400 is further included.

[0089] In a feasible embodiment of the present application, as Figure 7As shown, the safety device 400 is a paddle. The safety device 400 is telescopically arranged on the inner wall of the launching part, and protrudes towards the launching channel 122 and is arranged between the conveying component 311 and the launching end 123, strictly controlling the path of the fireworks launch, effectively preventing the fireworks from being accidentally pushed to the launching end 123 in case of an accident, and avoiding potential safety accidents caused by misoperation. The safety device 400 is connected to the first switch 313. When the first switch 313 is pressed, the safety device 400 retracts into the launching part 120, below the horizontal axis of the conveying component 311, and the fireworks in the loading groove 211 are pushed by the conveying component 311 to the launching end 123. Subsequently, the fireworks are launched through the acceleration channel 326 between the first flywheel 321 and the second flywheel 322. This design not only ensures safety through the blocking effect of the safety device 400 under normal conditions, but also enables the safety device 400 to give way in a timely and accurate manner when the operator performs normal launching operations, ensuring the smooth progress of the launching process. It not only ensures safety but also does not affect normal launching operations, providing a strong guarantee for the stable operation and safe use of the fireworks launching device.

[0090] Furthermore, in the above embodiment, the first switch 313 further includes a return spring 314. As Figure 4 shown, when the user presses the first switch 313, the return spring 314 will be compressed and store elastic potential energy. When the user releases the first switch 313, the elastic potential energy stored in the return spring 314 is instantly released. Under the action of the elastic force of the return spring 314, the first switch 313 quickly resets to its initial state. As the first switch 313 resets, the circuit is cut off, and the first motor 312 immediately stops running.

[0091] Since the first motor 312 is the power source for the operation of the conveying assembly 311, the conveying assembly 311 will immediately stop running if it loses power. From a safety perspective, during the fireworks launch process, if an unexpected situation occurs, the user only needs to release the first switch 313 to quickly stop the transmission of the conveying assembly 311, preventing unnecessary fireworks from being launched and effectively reducing the risks that may be caused by unexpected situations. For example, when it is found that the launch device is abnormal or there are safety hazards in the surrounding environment, the user can quickly respond and stop the operation in a timely manner to ensure the safety of themselves and others. In terms of the controllability of the operation, the existence of the return spring 314 allows the user to flexibly control the fireworks conveying process. The user can intermittently press and release the first switch 313 according to actual needs, thereby precisely controlling the conveyance of the conveying assembly 311 and achieving precise control over the number and rhythm of fireworks launches. The user can start and stop the conveying assembly 311 at intervals according to the rhythm and effect requirements of the performance, enabling the fireworks to be launched in sequence and at time intervals according to a carefully choreographed plan.

[0092] Furthermore, the fireworks launch device further includes a battery 600, which is electrically connected to the first power unit 310 and the second power unit 320 respectively, providing power for the stable operation of the entire device. Whether the first power unit 310 drives the conveying assembly to operate to push the fireworks, or the second power unit 320 drives the flywheel to rotate to impart acceleration to the fireworks, they all rely on the energy support provided by the battery 600. The battery 600 is fixedly arranged inside the handle portion 110. This arrangement not only makes full use of the internal space of the handle portion 110, making the overall structure of the device more compact and reasonable, avoiding space waste and device bulkiness caused by unreasonable component layout, but also effectively protects the battery 600 from external interference and damage during use, ensuring the stability of its performance.

[0093] Specifically, as Figure 3 、 Figure 4 and Figure 8As shown in the figure, the present application provides a fireworks launching device. First, it enters the loading preparation stage. The user first opens the lock cover 220 that is detachably connected to the launching part 120, smoothly extracts the cartridge 210 along the axis of the launching channel 122, loads the fireworks into the loading slots 211 circumferentially distributed on the cartridge 210. After loading is completed, the lock cover 220 is closed. At this time, the sealing cover 221 closely fits the loading end 121, the knob 222 is located at the center of the sealing cover 221 corresponding to the axis 212. After closing the lock cover 220, it forms a mechanical interlock with it. Rotating the knob 222 drives the axis 212 to rotate, aligning one of the loading slots 211 with the conveying assembly 311, and the limiting member 223 is embedded and fixed to prevent the cartridge 210 from shifting. Then it enters the fireworks pushing stage. First, the power switch 330 is turned on, and the indicator light immediately lights up, activating the battery 600, and the circuit in the fireworks launching device is in a conductive state. Then the second switch 325 is pressed, and the safety device 400 will retract to the inner wall of the launching part. The second motor 323 and the third motor 324 respectively connected to the first flywheel 321 and the second flywheel 322 are started, driving the two flywheels to rotate in opposite directions to form the acceleration channel 326. Finally, the first switch 313 fixed to the handle part 110 is pressed, and the first motor 312 inside the handle part 110 is started. By virtue of the engagement of the lower gear with the conveying assembly 311, the conveying assembly 311 parallel to the axis of the loading slot 211 is driven in a predetermined speed direction towards the launching end 123, and the fireworks are steadily pushed by friction, so that the fireworks reach the launching end 123. The fireworks located at the launching end 123 are launched through the acceleration channel 326. When the first switch 313 is released, the fireworks launching stops.

[0094] In another feasible embodiment of the present application, as Figure 2 and Figure 4 shown, a barrier 700 is provided at the launching end 123 of the fireworks launching device. The barrier 700 can be detachably connected to the launching end 123, which is convenient for installation and replacement according to actual needs; it can also be integrally formed with the launching end 123 to ensure the stability and sealing of the overall structure. When the fireworks launching program is started, the fireworks to be launched are first placed on the conveying assembly 311. The conveying assembly 311 is driven by the first motor 312 and operates at a stable and uniform speed, so as to ensure that the fireworks can be steadily transported forward along the established track. As the conveying assembly 311 continues to rotate, the fireworks are gradually sent into the launching channel 122.

[0095] As Figure 8As shown, when the fireworks successfully pass through the launch channel 122, they reach the position where the first flywheel 321 and the second flywheel 322 are located. At the moment when the fireworks come into contact with the flywheel, the special texture and texture distribution on the surface of the flywheel can effectively increase the friction with the fireworks. At the same time, the high-speed rotation of the flywheel will provide a powerful tangential thrust to the fireworks, enabling the fireworks to obtain sufficient initial velocity. Under the continuous action of the flywheel, the fireworks pass through the carefully designed acceleration channel 326. After being accelerated at high speed through the acceleration channel 326, the fireworks are launched at an extremely high speed. The launched fireworks pass directly through the cavity inside the barrier 700, ensuring that they are launched in a predetermined direction. When the fireworks move to a specific position in the cavity inside the barrier 700, they will touch the pre-set baffle 701, as Figure 1 shown. The purpose is to ensure that when the fireworks come into contact with the baffle 701, they can explode in the best posture. The fireworks debris generated by the explosion will orderly fall through the specially opened opening 702 at the lower part of the barrier 700, which can ensure that the fireworks debris can fall smoothly, and at the same time prevent the debris from rebounding or scattering during the falling process, further reducing the potential risk to the surrounding environment.

[0096] In summary, the present application discloses a fireworks launch device, including: a housing, the housing includes a handle portion and a launch portion connected to the handle portion, a launch channel is formed inside the launch portion, and a charge end and a launch end are formed on both sides of the launch channel; a charge assembly, the charge assembly includes a charge magazine and a locking cover, the charge magazine is arranged to match the launch channel, and a charge groove parallel to the launch channel is provided on the charge magazine to place a plurality of fireworks; the locking cover is arranged at the charge end and is detachably connected to the launch portion to enclose the charge magazine in the launch channel; a power assembly, the power assembly includes a first power portion arranged on one side of the launch channel and a second power portion arranged at the launch end. Among them, the first power portion includes a conveying assembly corresponding to the charge groove, and the fireworks in the charge groove are pushed to the launch end through the conveying assembly and are ejected by the second power portion to complete the fireworks launch. In the technical solution of the application, in the closed launch channel, the conveying assembly is arranged corresponding to the charge groove, realizing the automatic pushing of the fireworks from the charge end to the launch end. The operator does not need to directly hold the fireworks for ignition, reducing the ignition risk; its linear pushing mechanism avoids the friction hidden danger caused by the deviation or jamming of the fireworks during the movement. At the same time, through the phased control of the first power portion and the second power portion, the loading and launch actions are isolated to prevent mis-triggering; in addition, the conveying assembly operates under the closed state of the locking cover, further blocking the interference of external fire sources, and reducing the instantaneous collision between the fireworks and the channel through a stable and continuous thrust, thus forming multiple safety guarantees in the whole process of loading, pushing and launching.
