Description

Technical Field

[0001] This application relates to the field of fireworks technology, and more specifically to a fireworks launching device. Background Technology

[0002] Fireworks, an indispensable element of traditional festivals and celebrations, are popular in festivals, large-scale events, and personal entertainment, and have long provided people with a dazzling visual experience. However, the traditional handheld method of setting off fireworks presents many inconveniences and safety hazards.

[0003] When setting off handheld fireworks, the user's hand needs to be in close contact with the fireworks. If any abnormality occurs during the ignition process, such as the tube exploding or the fireworks deviating from their intended path, it can easily cause burns or other bodily injuries to the user. Furthermore, to ensure a successful ignition, the user often needs to maintain a fixed posture for a long time, which can easily lead to hand fatigue. This not only affects the ignition experience but may also cause the fireworks to lose control due to hand tremors, endangering the safety of those nearby.

[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a fireworks launching device that aims to solve the safety problems of handheld fireworks in the prior art.

[0006] The technical solution to the above-mentioned technical problems in this application is as follows:

[0009] The propellant loading assembly includes a propellant cartridge and a locking cover. The propellant cartridge is configured to match the launch channel and has a propellant slot parallel to the launch channel for holding a number of fireworks. The locking cover is disposed at the propellant end and detachably connected to the launch unit to enclose the propellant cartridge within the launch channel.

[0010] The power assembly includes a first power unit disposed on one side of the launch channel and a second power unit disposed on the launch end. The first power unit includes a conveying component disposed corresponding to the propellant trough. The conveying component pushes the fireworks in the propellant trough to the launch end and is then launched by the second power unit to complete the fireworks launch.

[0013] A plurality of the aforementioned propellant slots are arranged parallel to and evenly around the axis. Rotating the axis causes one of the propellant slots to align with the transmission assembly of the first power unit, thereby pushing the fireworks in the propellant slot to the launching end.

[0014] The aforementioned fireworks launching device, wherein the locking cover comprises:

[0015] A sealing cap is disposed at the propellant loading end and detachably connected to the launching part;

[0016] A knob is located at the center of the sealing cover and corresponds to the shaft. After the sealing cover is closed, the knob is engaged with the shaft. The shaft is rotated by the knob to change the loading slot corresponding to the conveying component.

[0017] A retaining spring is sleeved on the pivot of the knob and positioned between the knob and the pivot to secure the medicine cartridge after the sealing cover is closed.

[0018] The fireworks launching device is provided with a plurality of limiting grooves along the circumference of the knob. The limiting grooves are provided one-to-one with the charge slots. The charge end is provided with a limiting member corresponding to the limiting groove. When the knob is rotated, the limiting member is engaged with one of the limiting grooves to ensure that one of the charge slots corresponding to the limiting groove is positioned at the position corresponding to the conveying component.

[0019] The limiting member also includes an elastic member, which provides elastic force to the limiting member so as to ensure that the limiting member is engaged with the limiting groove when the knob is rotated to a position where the limiting groove corresponds to the limiting member.

[0020] The fireworks launching device, wherein the first power unit includes:

[0021] A first motor is fixed inside the handle portion;

[0022] The conveyor belt, which is connected to the first motor, moves toward the launching end under the drive of the first motor to push the fireworks in the charge tank to the launching end without squeezing the fireworks;

[0023] A first switch is located on the handle and is electrically connected to the first motor. When the first switch is pressed, the first motor starts and drives the conveyor belt to move.

[0024] The first switch further includes a reset spring; when the first switch is released, it resets, the first motor stops, and the conveyor belt stops moving. The fireworks launching device further includes:

[0025] A safety device is provided, which is retractably mounted on the inner wall of the launching part and protrudes towards the launching channel between the transmission assembly and the launching end. The safety device is connected to the first switch. When the first switch is pressed, the safety device retracts into the launching part, allowing the fireworks located at the launching end to be launched.

[0026] The second power unit includes:

[0027] A first flywheel and a second flywheel are fixed relative to each other inside the launching end, and an acceleration channel is formed between the first flywheel and the second flywheel. The acceleration channel is set corresponding to the conveyor belt, and the fireworks pushed by the conveyor belt enter the acceleration channel.

[0028] A second motor and a third motor, the second motor being connected to the first flywheel and the third motor being connected to the second flywheel, to drive the first flywheel and the second flywheel to rotate relative to each other, clamping the fireworks in the acceleration channel and launching the fireworks from the launching end;

[0029] The second switch is connected to the second motor and the third motor. When the second switch is pressed, the second motor and the third motor start and launch the fireworks in the acceleration channel.

[0030] The fireworks launching device, wherein the surfaces of the first flywheel and the second flywheel are covered with flexible protective rings to prevent the fireworks from being squeezed while ensuring the friction between the first flywheel and the second flywheel and the fireworks.

[0031] The fireworks launching device further includes:

[0032] The battery is fixedly disposed inside the handle and electrically connected to the first power unit and the second power unit respectively, so as to supply power to the first power unit and the second power unit;

[0033] A blocking component is detachably connected to the launching part and is disposed corresponding to the launching end. The blocking component is hollow to control the kinetic energy of the fireworks launched from the launching end.

[0034] The fireworks launching device further includes a power component that is connected to the power source, the first power unit, and the second power unit, and is used to control the circuit's on / off state.

[0035] The beneficial effects of this application are as follows:

[0036] This application discloses a fireworks launching device comprising: a housing, the housing including a handle portion and a launching portion perpendicular to the handle portion, the launching portion having a launching channel formed inside, and a propellant end and a launching end formed on both sides of the launching channel; a propellant assembly including a propellant cartridge and a locking cover, the propellant cartridge being matched with the launching channel and having a propellant slot parallel to the launching channel for holding a number of fireworks; the locking cover being disposed at the propellant end and detachably connected to the launching portion to enclose the propellant cartridge within the launching channel; and a power assembly including a first power unit disposed on one side of the launching channel and a second power unit disposed at the launching end, wherein the first power unit includes a conveying component corresponding to the propellant slot, the conveying component pushing the fireworks in the propellant slot to the launching end and being launched by the second power unit to complete the fireworks launching. In the proposed technical solution, within the enclosed launch channel, the conveying component is correspondingly set with the propellant tank, realizing the automated pushing of fireworks from the propellant end to the launch end. Operators do not need to directly hold the fireworks for ignition, reducing the risk of ignition. Its linear pushing mechanism avoids the friction hazards caused by the fireworks' deviation or jamming during movement. At the same time, through the phased control of the first and second power units, the loading and launching actions are isolated to prevent accidental triggering. In addition, the conveying component operates in a locked and closed state, further blocking external fire source interference, and reducing the instantaneous collision between the fireworks and the channel through stable and continuous thrust, thus forming multiple safety guarantees throughout the entire process of loading, pushing, and launching.

[0059] In the existing technology, the traditional handheld fireworks setting method has close-range safety hazards (such as tube explosion, burns caused by deflection) and lacks stable control over the setting angle and direction, which can easily lead to accidents due to operator fatigue or shaking.

[0060] In view of the above-mentioned problems in the prior art, this application provides a fireworks display device, which includes a housing 100, a propellant assembly 200 and a power assembly 300.

[0061] In one embodiment of this application, such as Figure 4As shown, the housing 100 includes a handle portion 110 and a launching portion 120 connected to the handle portion. In another feasible embodiment of this application, the handle portion 110 and the launching portion 120 are perpendicular to each other. A launching channel 122 is formed inside the launching portion 120. The launching channel 122 can be radially disposed within the launching portion 120. A charge end 121 and a launching end 123 are formed on both sides of the launching channel 122. The outer contour of the handle portion 110 is optimized according to the palm grip curve, conforming to ergonomics for stable grip and ensuring operational comfort. The surface of the handle portion 110 is distributed with anti-slip ribs, which can increase the friction between the handle and the hand during gripping, effectively preventing the ignition device from slipping out of the hand even in humid environments, thereby ensuring operational safety. The launch channel 122 is a single, straight, hollow internal cavity structure, the shape and size of which can be set according to the external shape of the housing 100. The launch channel 122 provides precise path guidance for the fireworks launch. Through geometric constraints and guidance mechanisms, the fireworks can only travel along this straight channel, minimizing deviations in the fireworks' trajectory that may be caused by channel curvature or irregularities, ensuring that the fireworks do not deviate from the axis of the launch channel 122 during launch. This allows the fireworks to be launched straight into the preset airspace with extremely high precision, improving the controllability of the fireworks launch device.

[0062] The drug loading assembly 200 includes a drug cartridge 210 and a locking cap 220, such as Figure 3 and Figure 7As shown, the propellant cartridge 210 matches the launch channel 122 to form a directional pull-out structure, enabling the propellant cartridge 210 to quickly and accurately complete positioning along the axis of the launch channel 122 during operation. Each pull-out action is smooth and unobstructed, greatly saving the time of loading fireworks and improving the efficiency of the launching device. The shape of the propellant cartridge 210 matches the launch channel 122. The shape of the propellant cartridge 210 is not unique; the cross-section of the propellant cartridge 210 can be circular, but it is not limited to this. The cross-sectional area of ​​the propellant cartridge 210 is slightly smaller than that of the launch channel 122, which can reduce friction with the inner wall of the launch channel 122 during the pull-out process, making the operation smoother and preventing jamming or stuck situations. This allows the propellant cartridge 210 to be smoothly pulled out and placed inside the launch channel 122. The propellant cartridge 210 has a plurality of propellant slots 211 arranged circumferentially. The propellant slots 211 can be the same or different in shape. Multiple fireworks are sequentially loaded into the propellant slots 211. The propellant slots 211 are set on the propellant cartridge 210 and are parallel to the launch channel 122, which can ensure that the fireworks are locked without deviation before launch. In addition, the propellant slots 211 can be used to hold different types of fireworks. By reasonably matching different types of fireworks, different types of fireworks can be combined and released according to a preset program, which can present a variety of colorful display effects when launched, bringing users a better display experience.

[0063] Furthermore, in the above embodiments, such as Figure 5 and Figure 6 As shown, the drug cartridge 210 includes a shaft 212 and a plurality of drug loading slots 211.

[0064] The shaft 212 is precisely coaxially set based on the radial shaft 212 of the launch channel 122. When the locking cover 220 is closed, one end of the shaft 212 is engaged with the locking cover 220, and the other end of the shaft 212 is connected to the launch end. This ensures that the propellant cartridge 210 maintains zero offset positioning when it is simultaneously subjected to radial firework gas impact force and axial recoil force within the launch channel, avoiding axial movement or radial sway of the propellant cartridge due to vibration. This embodiment significantly improves the impact resistance and adaptability of the propellant assembly 200 through mechanical transmission path optimization and dynamic sealing synergy, and ensures the repeatability of the shaft 212 holding structure during rapid assembly and disassembly.

[0065] The charge tanks 211 are circumferentially distributed around the axis 212, such as Figure 6As shown, the centerline of each of the charge slots 211 is parallel to the axis 212 and parallel to the radial axis of the launch channel 122. The opening of the charge slot 211 is located on the circumference of the charge cartridge 210. Meanwhile, considering the stability of the fireworks after loading, the width of the opening is designed to be smaller than the diameter of the fireworks. This can prevent the fireworks from falling out due to shaking during transportation and operation, and can also provide a suitable constraint environment for the fireworks, ensuring the stable performance of the launch device. By rotating the axis 212 stepwise, the openings of each charge slot 211 are aligned with the transmission component 311 in the power component 300. A single loading can realize the automatic sequential switching and launch of multiple types of fireworks, forming a dynamically changing combination of firing effects, which significantly enhances the richness of the performance. When the target propellant trough 211 is aligned with the delivery assembly 311, the firework, under its own weight, presses against the delivery assembly 311 through the opening of the propellant trough 211, using just the right pressure to make the firework and the delivery assembly 311 come into close but gentle contact. Then the delivery assembly 311 is activated, and the friction between the delivery assembly 311 and the firework pushes the firework to the launching end 123. This setting ensures that sufficient friction can be generated between the two while avoiding damage to the firework due to excessive pressure. When the device is in operation, the circumferential layout of the propellant slots 211 shields any propellant slots 211 that are not aligned with the conveying component 311. This means that, from a physical structure perspective, apart from the propellant slots 211 currently connected to the push path that can participate in the fireworks launch process, the fireworks in the other propellant slots 211 are physically isolated. This avoids the risk of accidental triggering or chain ignition from collisions, electrostatic discharges, or other triggering sources, providing a rock-solid guarantee for the safe and stable operation of the fireworks launch device.

[0066] In one embodiment of this application, such as Figure 3 , Figure 10 and Figure 11 As shown, the locking cover 220 is disposed on the propellant loading end 121 and closes the launching part 120 by means of hinge, ensuring that the propellant cartridge 210 is rigidly fixed in the launching channel 122. The propellant cartridge 210 remains fixed with zero displacement when subjected to axial recoil or vibration in the launching channel 122, avoiding the risk of propellant cartridge displacement or slippage due to impact. The inner side of the locking cover 220 is tightly fitted to the launching channel 122, forming an airtight space in the closed state, which not only prevents external moisture and dust from entering the launching channel, but also improves the safety of the operating environment.

[0067] Furthermore, in the above embodiments, the lock cover 220 includes a sealing cover 221, a knob 222, and a retaining spring 225, as shown below. Figure 5 As shown.

[0068] In another feasible embodiment of this application, the sealing cap 221, located at the propellant end 121, can also be engaged with the launching part 120. In the closed state, it aligns and engages with the end of the shaft 212, forming a rigid torque transmission path. After loading, the sealing cap 221 is tightly fitted onto the propellant end 121 to achieve a pressure seal, forming a reliable sealing structure. This seal not only prevents the reverse impact force generated during fireworks launch, ensuring the effective utilization of launch power, but also prevents external dust and debris from entering the launching part 120 and damaging the device, thereby extending the device's service life and improving its stability and reliability. The knob 222 is located at the geometric center of the sealing cap 221 and corresponds to the shaft 212. After the sealing cap 221 is closed, the knob 222 and the shaft 212 engage to form a mechanical interlock system. Rotating the shaft 212 via the knob 222 drives the moving propellant cartridge 210 corresponding to the conveying assembly 311 to be positioned. This correspondence ensures a precise fit between the knob 222 and the shaft 212. When the sealing cover 221 is closed, the knob 222 and the shaft 212 are tightly engaged, forming a stable connection. This engagement is like a key inserted into a lock, allowing the rotation of the knob 222 to be directly transmitted to the shaft 212, achieving synchronous movement between the two. By rotating the knob 222, the user can easily control the rotation of the shaft 212. Since several propellant slots 211 are sequentially arranged around the upper edge of the propellant cartridge 210, and the rotation of the shaft will drive the entire propellant cartridge 210 to rotate, as the knob 222 is rotated, different propellant slots 211 will sequentially rotate to the positions corresponding to the conveying assembly 311. In this way, the user can flexibly select the type and sequence of fireworks to be launched according to their needs. The design and coordination of the sealing cover 221 and the knob 222 make the fireworks launching device more convenient and efficient to operate, and more functional and diverse, bringing users a better user experience and a more dazzling fireworks viewing effect.

[0069] Specifically, such as Figure 7As shown, the shaft 212 and the sealing cover 221 are connected by a polygonal coupling 226. Optionally, the polygonal coupling 226 is hexagonal. The polygonal coupling 226 is disposed between the charge slot 211 and the sealing cover 221, and at the position of the shaft 212. Specifically, the polygonal coupling 226 engages with the charge slot 211 through a corresponding hole on the shaft 212. The multiple planes of the polygonal coupling 226 are evenly distributed, forming a full-circumferential rigid contact with the corresponding hole on the charge slot 211. The geometric characteristics of the polygon provide higher torsional stiffness, avoiding slippage or free rotation caused by uneven force during knob operation (especially in high torque scenarios). The polygonal coupling 226 corresponds to the charge slot 211 and the limiting slot 224. The polygonal coupling 226 enables the coordinated operation of the charge slot 211 and the limiting slot 224, ensuring precise alignment between the charge slot 211 and the conveying assembly 311. Furthermore, the polygonal coupling 226 does not require strict angle calibration when engaging with the sealing cap; during closure, it automatically guides the device to the correct position through the progressive meshing of multiple planes, simplifying the assembly process.

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

[0071] like Figure 7 As shown, one end of the fixing spring 225 abuts against the lock 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 direct collisions between components, and avoid damage. The fixing spring 225 can maintain stable performance for a long time, repeatedly undergoing elastic deformation and recovery without showing obvious fatigue or damage.

[0072] Furthermore, in the above embodiments, such as Figure 8 and Figure 9As shown, the knob 222 is provided with a plurality of limiting grooves 224 along its circumference. Each limiting groove 224 corresponds to a different medication slot 211. The medication loading end 121 is provided with a limiting member 223 corresponding to each limiting groove 224. When the user rotates the knob 222, the limiting member 223 rotates with the knob 222 until it engages with one of the limiting grooves 224, ensuring that one medication slot 211 corresponding to the limiting groove 224 is positioned at the position corresponding to the conveying component 311. The setting of the limiting member 223 and the limiting grooves 224 ensures that the medication cartridge 210 is fixed after rotating the knob 222, and ensures that only one medication slot 211 is precisely positioned at the position corresponding to the conveying component 311. When one of the propellant slots 211 is aligned with the conveying assembly 311, the limiting member 223 will quickly engage with the limiting slot 224 to the corresponding position, firmly fixing the propellant cartridge 210 in the current position. This fixing method can effectively prevent the propellant cartridge 210 from rotating unexpectedly due to vibration, impact, or other factors during the fireworks launch process.

[0073] The limiting member 223 also includes an elastic member 227, which provides elastic force to the limiting member 223 so that when the knob 222 is rotated to a position where the limiting groove 224 corresponds to the limiting member 223, the limiting member 223 is engaged with the limiting groove 224.

[0074] Specifically, the elastic element 227 is a spring, such as... Figure 7 As shown, under frequent operation or vibration, the device will generate significant impact, leading to 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 into position, reducing metal fatigue and wear, and extending the service life of the limiting groove 224 or the limiting member 223. The elastic member 227 may provide better adaptability. The limiting groove 224 may change in size due to manufacturing errors or long-term wear; the elasticity of the elastic member 227 can compensate for this change, ensuring that the limiting member 223 can still reliably engage in the hole and maintain fixed stability. The limiting member 223 may not fit tightly after the hole wears, resulting in insecure fixation. When the limiting member 223 is spring-loaded, the spring will be compressed when entering the limiting groove, providing continuous clamping force while allowing for a certain degree of elastic deformation. The elastic member 227 may make operation smoother. When the user rotates the knob 222, the limiting member 223 can slide more easily into the limiting groove 224 under the action of the elastic member 227, reducing the feeling of jamming. Especially when frequent rotation and adjustment are required, the elastic feedback of the elastic member 227 may improve the user experience, making the rotation process smoother while still maintaining accurate positioning.

[0075] The presence of the limiting member 223 and the limiting groove 224 greatly improves the accuracy and reliability of fireworks launch. During launch, the stable propellant cartridge 210 ensures the fireworks are accurately placed on the conveying assembly 311. The conveying assembly 311 has a stable conveying function, ensuring the fireworks are smoothly pushed to the launch end 123 and launched according to a predetermined trajectory and sequence. Without the fixing of the limiting member 223 and the limiting groove 224, the propellant cartridge 210 may shift at the moment of launch, causing the propellant groove 211 to deviate from the position of the conveying assembly 311, preventing the fireworks from being properly loaded and launched, affecting the overall effect and rhythm of the fireworks display. Furthermore, the limiting member 223 and the limiting groove 224 also make the device operation more convenient and efficient. The user only needs to turn the knob 222 to the appropriate position, and the limiting member 223 and the limiting groove 224 will automatically lock and fix the device, eliminating the need for additional complex operations to ensure the stable position of the propellant cartridge 210. This not only saves time but also reduces the difficulty of operation. Even first-time users can easily get started and quickly launch different types of fireworks in an orderly manner, adding more excitement and fun to the fireworks display.

[0076] Furthermore, in another embodiment of this application, such as Figure 6 As shown, the power assembly 300 achieves efficient coordination between firework propulsion and launch through a phased power transmission and precise control design. The power assembly 300 includes a first power unit 310 disposed on one side of the launch channel 122 and a second power unit 320 disposed on the launch end 123. The power assembly 300 also includes a power switch 330. The two power units cooperate with each other through a clever power distribution and transmission mechanism, providing precise power support for different stages of the firework's movement. The first power unit 310 includes a conveying assembly 311 corresponding to the propellant trough 211. The conveying assembly 311 is made of a high-temperature resistant and anti-static composite material, effectively ensuring the safety of the firework during propulsion. The conveying assembly 311 is arranged parallel to the axis of the propellant trough 211, ensuring that the firework always moves linearly along the radial direction of the launch channel 122 during propulsion, avoiding deflection or tilting.

[0077] In another embodiment of this application, the power assembly 300 includes the power switch 330, which is connected to the battery 600, the first power unit 310 and the second power unit 320 respectively, and the power switch 330 is used to control the circuit to turn on and off.

[0078] In one feasible embodiment of this application, the fireworks launching device further includes indicator lights located on both sides of the propellant 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 propellant cartridge 210 illuminate. The indicator lights have a dual function: firstly, they serve a decorative purpose, enriching the fireworks launching experience; secondly, they indicate whether the fireworks launching device is in working mode.

[0080] Furthermore, in the above embodiments, 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] like Figure 8 As shown, the first flywheel 321 and the second flywheel 322 are fixedly arranged side by side inside the launching end 123. The center line connecting the first flywheel 321 and the second flywheel 322 is perpendicular to the launching channel 122. The two flywheels rotate synchronously, and a certain gap is maintained between the first flywheel 321 and the second flywheel 322. This gap allows the fireworks to pass through smoothly, preventing them from getting stuck or having poor acceleration due to excessively large gaps. The first flywheel 321 and the second flywheel 322 rotate in opposite directions, forming an acceleration channel 326 between them. Figure 8 As shown, the acceleration channel 326 is configured corresponding to the conveying component 311. Fireworks pushed by the conveying component 311 arrive at the launching end 123 and enter the acceleration channel 326 for launch. After being pushed to the launching end 123 by the conveying component 311, the fireworks leave the conveying component 311 and, through the first flywheel 321 and the second flywheel 322, gain a significant acceleration under the powerful friction and clamping force generated by the high-speed rotation of the flywheels. This acceleration mechanism provided by the flywheels greatly increases the initial velocity of the fireworks compared to the traditional single-push launch method. Due to the significant increase in initial velocity, the high-speed launched fireworks can overcome more air resistance and the influence of gravity, thereby achieving a longer range.

[0082] Specifically, such as Figure 6 and 8 As 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 motors can directly and effectively drive the flywheels to rotate relative to each other, thereby driving the first flywheel 321 and the second flywheel 322 to rotate relative to each other. The second switch 325 is connected to the second motor 323 and the third motor 324. When the second switch 325 is pressed, the second motor 323 and the third motor 324 are activated, launching the fireworks from the launch channel 122.

[0083] Furthermore, the surfaces of the first flywheel 321 and the second flywheel 322 are covered with flexible protective rings. These rings are uniformly and seamlessly attached to the surfaces of the flywheels, ensuring a tight and stable bond. Whether under the powerful centrifugal force generated during high-speed rotation or during friction and collision with the fireworks, the flexible protective rings remain firmly in place, preventing loosening or detachment and ensuring stable functioning. In addition, the flexible protective rings play a crucial dual role. On one hand, they maintain the friction between the first and second flywheels 321 and the fireworks, increasing the contact area with the fireworks surface during rotation. This provides the fireworks with a powerful driving force, enabling them to gain sufficient acceleration in the acceleration channel 326 and be successfully launched from the launch end 123. On the other hand, the flexible protective rings effectively prevent compression of the fireworks. Fireworks have a relatively fragile structure; direct contact with the hard flywheel and subsequent compression could damage their internal structure, affecting the ignition effect or causing danger. The flexible protective ring possesses excellent elasticity and cushioning properties. When the flywheel clamps the fireworks, it absorbs and disperses some of the pressure, acting like a soft cushioning pad to evenly distribute the pressure across the fireworks' surface, preventing excessive localized pressure. This design significantly improves the success rate and safety of fireworks launches. Because the fireworks are well protected during launch, the risk of damage due to compression is avoided, ensuring each firework is launched in optimal condition, thus significantly enhancing the fireworks display's effect. Simultaneously, it reduces potential safety hazards caused by fireworks damage, providing users with a more reliable and worry-free experience.

[0084] Furthermore, in the above embodiments, such as Figure 6 As shown, the first power unit includes the transmission assembly 311, the first motor 312, and the first switch 313.

[0085] like Figure 5 and Figure 6 As shown, the first switch is disposed on the handle portion 110, and the first motor 312 is fixed inside the handle portion 110. This not only provides reliable support for the first motor 312, allowing it to remain stable during operation and reducing the risk of damage and failure caused by shaking or vibration, but also makes full use of the internal space of the handle portion 110, making the structure of the entire fireworks launching device more compact and reasonable. It achieves an efficient layout within a limited space, improving the overall aesthetics and practicality of the device. The first motor 312 is disposed below the conveying assembly 311. In another feasible embodiment of this application, as shown... 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 axial propulsion through a worm gear transmission component 500. The worm 501 is the driving component, coaxially connected to the first motor 312, and the worm gear 502 is the driven component, meshing with the conveying component 311. The axes of the two are orthogonally distributed in space. Through the transmission method of the worm 501, the high-speed, low-torque motion of the motor can be converted into the low-speed, high-torque motion of the worm gear 502, achieving a 90-degree vector conversion of the rotation direction to drive the conveying component 311, achieving smooth and noiseless transmission. Through this 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 starts, the motor shaft drives the gear to rotate. The gear meshes with the transmission components of the transmission assembly 311, realizing efficient power transmission and ensuring that the transmission assembly 311 can operate stably and smoothly. This provides a solid power guarantee for the propulsion of the fireworks, enabling the fireworks to be accurately delivered 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. When the first switch 313 is pressed, the first motor 312 starts. The power generated by the first motor 312 drives the transmission component 311 to start transmission through the meshing of gears. The power generated by the first motor 312 is smoothly and accurately transmitted to the transmission component 311, so that the transmission component 311 can run stably at a predetermined speed and direction, providing stable and reliable power support for the delivery of fireworks and ensuring that the fireworks can be accurately delivered to the predetermined position.

[0087] Specifically, when the user presses the first switch 313, the first motor 312 starts rapidly and begins to operate at high speed. Driven by the first motor 312, the conveying component 311 immediately begins 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 charge tank 211 to the launching end 123 without compressing the fireworks. This provides sufficient friction to propel the fireworks forward while avoiding damage to them, ensuring that each firework arrives at the launching position intact.

[0088] Furthermore, the above embodiments also include a safety device 400.

[0089] In one feasible embodiment of this application, such as Figure 7As shown, the safety device 400 is a lever, which is retractably mounted on the inner wall of the launching section and protrudes towards the launching channel 122 between the conveying assembly 311 and the launching end 123. This strictly controls the path of the fireworks launch, effectively preventing the fireworks from being accidentally pushed to the launching end 123 in case of an accident, thus avoiding potential safety accidents caused by misoperation. The safety device 400 is connected to the first switch 313. When the switch is pressed, the safety device 400 retracts into the launching section 120, below the horizontal axis of the conveying assembly 311. The fireworks in the propellant tank 211 are pushed by the conveying assembly 311 to the launching end 123, and then launched through the acceleration channel 326 between the first flywheel 321 and the second flywheel 322. This design ensures safety through the blocking function of the safety device 400 under normal conditions, and also allows the safety device 400 to retract promptly and accurately during normal launch operations, ensuring the smooth progress of the launch process. It guarantees safety without affecting normal launch operations, providing a strong guarantee for the stable operation and safe use of the fireworks launch device.

[0090] Furthermore, in the above embodiments, the first switch 313 further includes a reset spring 314, such as... Figure 4 As shown, when the user presses the first switch 313, the return spring 314 is compressed, storing elastic potential energy. When the user releases the first switch 313, the stored elastic potential energy in the return spring 314 is released instantaneously. Under the action of the elastic force of the return spring 314, the first switch 313 quickly resets, returning to its initial state. With the reset of the first switch 313, the circuit is cut off, and the first motor 312 immediately stops operating.

[0091] Since the first motor 312 is the power source for the operation of the transmission component 311, the transmission component 311 will immediately stop operating if it loses power. From a safety perspective, during the fireworks launch process, if an emergency occurs, the user only needs to release the first switch 313 to quickly stop the transmission of the transmission component 311, preventing unnecessary fireworks from being launched and effectively reducing the danger that may be caused by unexpected situations. For example, when an abnormality is found in the launching device or there are safety hazards in the surrounding environment, the user can react quickly and stop the operation in time to ensure the safety of themselves and others. In terms of operational controllability, the presence of the reset spring 314 allows the user to flexibly control the fireworks delivery process. The user can intermittently press and release the first switch 313 according to actual needs, thereby precisely controlling the transmission of the transmission component 311 and achieving precise control over the number and rhythm of fireworks launches. The user can start and stop the transmission component 311 at intervals according to the rhythm and effect requirements of the performance, allowing the fireworks to be launched sequentially in a carefully arranged order and time interval.

[0092] Furthermore, the fireworks launching device also includes a battery 600, which is electrically connected to both the first power unit 310 and the second power unit 320, providing power for the stable operation of the entire device. Whether the first power unit 310 drives the conveyor assembly to propel the fireworks, or the second power unit 320 drives the flywheel to accelerate the fireworks, both rely on the energy provided by the battery 600. The battery 600 is fixedly installed 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 its stable performance.

[0093] Specifically, such as Figure 3 , Figure 4 and Figure 8As shown, this application provides a fireworks launching device. First, in the loading preparation stage, the user opens the lock cover 220, which is detachably connected to the launching section 120, and smoothly pulls out the propellant cartridge 210 along the axis of the launching channel 122. Fireworks are loaded into the propellant slots 211 distributed circumferentially on the propellant cartridge 210. After loading, the lock cover 220 is closed. At this time, the sealing cover 221 tightly fits against the propellant 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 is mechanically interlocked with the axis. Rotating the knob 222 causes the axis 212 to rotate, aligning one of the propellant slots 211 with the conveying assembly 311. The limiting member 223 is embedded and fixed to prevent displacement of the propellant cartridge 210. Next, in the fireworks launching stage, the power switch 330 is turned on, the indicator light illuminates, the battery 600 is activated, and the circuit in the fireworks launching device is in a continuous state. Then, pressing the second switch 325 causes the safety device 400 to retract into the inner wall of the launching section. The second motor 323 and the third motor 324, which are respectively connected to the first flywheel 321 and the second flywheel 322, start, driving the two flywheels to rotate in opposite directions to form the acceleration channel 326. Finally, pressing the first switch 313 fixed to the handle 110 starts the first motor 312 inside the handle 110. With the engagement of the lower gear with the transmission assembly 311, the transmission assembly 311, which is parallel to the axis of the charge slot 211, drives towards the launching end 123 at a predetermined speed and direction. Relying on friction, the fireworks are smoothly pushed to the launching end 123. The fireworks located at the launching end 123 are launched through the acceleration channel 326. Releasing the first switch 313 stops the fireworks launch.

[0094] In another feasible embodiment of this application, such as Figure 2 and Figure 4 As shown, the launching end 123 of the fireworks launching device is equipped with a barrier 700. The barrier 700 and the launching end 123 can be detachably connected for easy installation and replacement according to actual needs; alternatively, it can 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, thereby ensuring that the fireworks can be transported smoothly forward along the predetermined track. As the conveying assembly 311 continues to rotate, the fireworks are gradually fed into the launching channel 122.

[0095] like Figure 8As shown, after the fireworks successfully pass through the launch channel 122, they arrive at the positions of the first flywheel 321 and the second flywheel 322. At the moment the fireworks contact the flywheels, the special texture and distribution of the flywheel surface effectively increase the friction between the fireworks and the flywheels. Simultaneously, the high-speed rotation of the flywheels provides a strong tangential thrust to the fireworks, giving them sufficient initial velocity. Under the continuous action of the flywheels, the fireworks pass through the carefully designed acceleration channel 326. After high-speed acceleration through the acceleration channel 326, the fireworks are launched at extremely high speed. After launch, the fireworks pass directly through the cavity inside the barrier 700, ensuring they are launched in the predetermined direction. When the fireworks reach a specific position within the cavity inside the barrier 700, they will touch the pre-set baffle 701, such as... Figure 1 As shown, its purpose is to ensure that the fireworks explode in the optimal posture when they come into contact with the baffle 701. The fireworks debris generated by the explosion will fall in an orderly manner through the specially opened opening 702 at the bottom of the baffle 700, which can ensure that the fireworks debris falls smoothly and prevent the debris from bouncing or scattering during the falling process, further reducing the potential risks to the surrounding environment.

[0096] In summary, this application discloses a fireworks launching device, comprising: a housing, the housing including a handle and a launching part connected to the handle, the launching part having a launching channel formed inside, and a propellant end and a launching end forming on both sides of the launching channel; a propellant assembly including a propellant cartridge and a locking cover, the propellant cartridge being matched with the launching channel and having a propellant slot parallel to the launching channel for holding a number of fireworks; the locking cover being disposed at the propellant end and detachably connected to the launching part to enclose the propellant cartridge within the launching channel; and a power assembly including a first power unit disposed on one side of the launching channel and a second power unit disposed at the launching end, wherein the first power unit includes a conveying component corresponding to the propellant slot, the conveying component pushing the fireworks in the propellant slot to the launching end and being launched by the second power unit to complete the fireworks launching. In the proposed technical solution, within the enclosed launch channel, the conveying component is correspondingly set with the propellant tank, realizing the automated pushing of fireworks from the propellant end to the launch end. Operators do not need to directly hold the fireworks for ignition, reducing the risk of ignition. Its linear pushing mechanism avoids the friction hazards caused by the fireworks' deviation or jamming during movement. At the same time, through the phased control of the first and second power units, the loading and launching actions are isolated to prevent accidental triggering. In addition, the conveying component operates in a locked and closed state, further blocking external fire source interference, and reducing the instantaneous collision between the fireworks and the channel through stable and continuous thrust, thus forming multiple safety guarantees throughout the entire process of loading, pushing, and launching.
