Description

Technical Field

[0001] This application relates to the field of fireworks technology, specifically to a fireworks projectile and fireworks having the same. Background Technology

[0002] Existing fireworks, whether large-scale or small handheld toy fireworks, all require manual ignition of the fuse using an open flame or remote electronic control to ignite the propellant. The propellant then launches the firework projectile, igniting the projectile simultaneously with the propellant. After the projectile ascends into the air, it explodes to create various effects.

[0003] Fireworks made based on the above principles (such as "beaded tubes" and "handheld Gatling guns") are susceptible to moisture damage during transportation and storage because the fuse is externally attached to the firework shell, affecting product yield. Furthermore, the propellant used in launching the firework shell carries the risk of the tube exploding, posing a safety hazard. Summary of the Invention

[0004] In view of the above-mentioned technical problems, this application provides a firework shell and a firework having the same, which aims to solve the problems existing in the existing firework shells as described in the background art.

[0005] To achieve the above objectives, this application proposes a firework shell, comprising an outer tube, an inner shell for forming fireworks through explosion, a separator, a igniter, and a fuse. The separator is disposed within the outer tube and divides the internal space of the outer tube into an inner shell housing and an igniter housing. The inner shell is installed within the inner shell housing, and the igniter is installed within the igniter housing. The separator has a through hole, and the fuse passes through the through hole and connects the igniter and the inner shell. The igniter is used to explode upon being subjected to external impact to ignite the fuse, thereby detonating the inner shell through the fuse to form fireworks.

[0006] Optionally, the firework shell further includes a bottom cover and a buffer. The bottom cover is detachably disposed at one end of the outer cylinder relative to the ignition powder receiving portion. The bottom cover is used to receive external force to compress the ignition powder placed in the ignition powder receiving portion and cause it to explode. The buffer is disposed at one end of the outer cylinder relative to the inner shell receiving portion.

[0007] Optionally, the firework shell also includes a fuse for passing through the through hole to connect the ignition powder and the inner shell.

[0008] This application also provides a firework, including a launching mechanism and a firework shell as described above, wherein the launching mechanism is used to mechanically apply an impact force to the ignition powder of the firework shell to detonate the ignition powder.

[0009] Optionally, the launching mechanism includes a launching tube, an elastic element disposed inside the launching tube, and an impact head. The two ends of the elastic element abut against the impact head and the inner sidewall of the launching tube, respectively. The impact head is used to strike the bottom cover of the firework shell under the drive of the elastic element.

[0010] Optionally, the launching mechanism includes a launching tube, an elastic element disposed inside the launching tube, a piston, and a piston cavity. The two ends of the elastic element abut against the piston and the inner sidewall of the launching tube, respectively. The piston is used to reciprocate within the piston cavity under the drive of the elastic element to draw in air outside the piston cavity or expel air from the piston cavity, thereby causing the expelled air to strike the bottom cover of the firework shell.

[0011] Optionally, the inner wall of the launching tube gathers in the radial direction to form a vent hole, and the end of the piston cavity away from the elastic element protrudes outward to form a gas gathering part, which is disposed in the vent hole.

[0012] Optionally, the launching mechanism further includes a magazine for filling the firework shell, the magazine being disposed on the launching tube and communicating with the launching tube.

[0013] Optionally, the launching tube has a firework receiving portion for mounting the firework shell, the firework shell receiving portion having a first part that connects to the piston cavity or the impact head and a second part for the firework shell to slide along the opening direction of the launching tube, the magazine being disposed on the first part.

[0014] Optionally, the launching mechanism further includes a control unit and a drive motor. The control unit is electrically connected to the drive motor, which is disposed in the magazine and is used to drive the firework shell installed in the magazine to move to the first part of the launching tube under the control of the control unit.

[0015] This application places an insulating component with a through hole inside the outer tube, with the inner projectile and igniter placed on opposite sides of the insulating component. An impact force is applied to the end of the outer tube containing the igniter to detonate the inner projectile, thus creating a firework. No external fuse or open flame is required, making it less susceptible to weather conditions and highly playable. The igniter and inner projectile burn sequentially; the burning speed can be dynamically adjusted by changing the composition of the igniter, thereby delaying the detonation of the inner projectile and avoiding the risk of tube explosion. Furthermore, when used in conjunction with the launching mechanism proposed in this application, users can manually control the launch rhythm of the firework projectile, offering significant advantages over traditional fireworks in terms of versatility, fun, safety, and ease of use.

Therefore, they should not be construed as limitations on the present invention.

[0026] Moreover, the terms "first," "second," "third," etc., are merely used to distinguish elements with similar attributes, rather than to indicate or imply relative importance or a specific order.

[0027] Furthermore, the terms “including,” “comprising,” or any other variations thereof are intended to cover non-exclusive inclusion, which includes not only the elements listed but also other elements not expressly listed.

[0028] Please refer to Figure 1 and Figure 2This application proposes a firework shell 10, which includes an outer tube 110, an inner shell for forming fireworks through explosion, an isolation member 130, and a igniter 140. The isolation member 130 is disposed inside the outer tube 110 and divides the internal space of the outer tube 110 into an inner shell receiving portion 111 and an igniter receiving portion 112. The inner shell 120 is installed in the inner shell receiving portion 111, and the igniter 140 is installed in the igniter receiving portion 112. The igniter 140 is used to explode when subjected to external impact force to detonate the inner shell 120 and thus form fireworks. Specifically, in one embodiment, the outer cylinder 110 is a one-piece cylindrical structure with an opening at one end communicating with the internal space. A spacer 130 is snapped onto the inner wall of the outer cylinder 110, dividing the internal space into two areas: an inner bullet housing 111 for housing the inner bullet 120 and a ignition powder housing 112 for housing the ignition powder 140. A through-hole 131 on the spacer 130 allows direct or indirect contact between the inner bullet 120 and the ignition powder 140. The ignition powder 140 may have a chemical composition similar to that of common firecrackers (containing potassium chlorate and red phosphorus). Upon impact or compression, it explodes, producing a flame or spark within a short time. By adjusting the composition of the ignition powder 140, its burning rate within the ignition powder housing 112 can be dynamically adjusted, thereby delaying the detonation of the inner bullet 120 and avoiding the risk of the cylinder exploding. In actual implementation, by applying an impact force to the outer wall of the outer cylinder 110 corresponding to the ignition powder 140, the ignition powder 140 placed in the ignition powder receiving part 112 will explode and burn when subjected to external impact force. The open flame or sparks generated during the gradual burning process ignite the inner bullet 120 located in the inner bullet receiving part 111 through the through hole 131, achieving the effect of the inner bullet 120 exploding to form fireworks.

[0029] Optionally, the firework shell 10 also includes a bottom cover 150 and a buffer 160. The bottom cover 150 is detachably disposed at one end of the outer cylinder 110 relative to the ignition powder receiving portion 112. The bottom cover 150 is used to receive external force to compress the ignition powder 140 placed in the ignition powder receiving portion 112 and cause it to explode. The buffer 160 is disposed at one end of the outer cylinder 110 relative to the inner shell receiving portion 111. Specifically, a detachable bottom cover 150 is installed at the port of the outer cylinder 110 relative to the ignition powder receiving portion 112, and the diameter of the bottom cover 150 is slightly larger than the inner diameter of the outer cylinder 110. This achieves the purpose of preventing the leakage of the ignition powder 140 while also compressing the ignition powder 140 under the action of external force, so that the ignition powder 140 can burn more completely and avoid the occurrence of duds. In this embodiment, the external impact force is applied directly to the bottom cover 150. When the bottom cover 150 is subjected to the external impact force, it displaces inward toward the outer cylinder 110 and, together with the spacer 130, compresses the ignition powder 140 placed in the ignition powder receiving portion 112, thereby causing it to explode. Furthermore, to prevent the firework shell 10 from impacting people or objects and causing damage during flight (before the inner shell 120 explodes), at least one buffer 160 is provided at the end of the firework shell 10. The buffer 160 is made of a soft material, such as rubber, foam, or sponge, and is not limited thereto. Preferably, at least one buffer 160 is provided at the end of the outer cylinder 110 opposite to the inner shell receiving portion 111.

[0030] Optionally, the firework shell 10 also includes a fuse 170, which passes through a through-hole 131 to connect the igniter 140 and the inner shell 120. Specifically, the fuse 170 passes through the through-hole 131 on the separator 130, allowing the inner shell 120 to directly contact the igniter 140. When the igniter 140 is subjected to an external impact, it explodes and burns, igniting the fuse 170 connected to it at the moment of combustion. This ignited fuse 170 then detonates the inner shell 120 located in the inner shell receiving portion 111, achieving the effect of the inner shell 120 exploding to form a firework. In actual implementation, the length of the fuse 170 can be adjusted to dynamically adjust the time difference between the explosion of the igniter 140 and the ignition of the fuse 170, thereby further delaying the time for the inner shell 120 to detonate and form a firework, avoiding the risk of the shell exploding.

[0031] Please refer to Figure 3 This application also provides a firework, including a launching mechanism 20 and a firework shell 10 as described above. The launching mechanism 20 is used to mechanically apply an impact force to the ignition powder 140 of the firework shell 10 to detonate the ignition powder 140. Specifically, the mechanical means can be, for example, collision between objects, using an external tool to push against it, air compression, electric power, gear transmission, etc., and is not limited to this.

[0032] Optionally, the launching mechanism 20 includes a launching tube 210, an elastic element 220 disposed within the launching tube 210, and an impact head 230. The two ends of the elastic element 220 abut against the impact head 230 and the inner wall of the launching tube 210, respectively. The impact head 230 is used to strike the bottom cover 150 of the firework shell 10 under the drive of the elastic element 220. In this embodiment, the launching mechanism 20 applies an impact force to the ignition powder 140 of the firework shell 10 to ignite the ignition powder 140 by means of a spring-loaded firing pin. Specifically, the launching mechanism 20 includes a launching tube 210, an elastic element 220 disposed within the launching tube 210, and an impact head 230. One end of the elastic element 220 is fixed to the inner wall of the launching tube 210, and the other end is fixed to the impact head 230. In the illustrated structure, the shape of the impact head 230 is approximately that of a bullet, with one end connected to the elastic element 220 being flat (shell) and the other end being hemispherical (bullet). When the elastic element 220 is compressed, the elastic potential energy generated is converted into kinetic energy when it is released, so that the impact head 230 impacts the bottom cover 150 of the firework shell 10 placed inside the launch tube 210. Under the action of the impact force, the firework shell 10 is launched on one hand, and the igniter 140 explodes and ignites the inner shell 120 to achieve the effect of fireworks in the air.

[0033] Please refer to Figure 4The launching mechanism 20 includes a launching tube 210, an elastic element 220 disposed within the launching tube 210, a piston 240, and a piston cavity 250. The two ends of the elastic element 220 abut against the piston 240 and the inner wall of the launching tube 210, respectively. The piston 240 reciprocates within the piston cavity 250 under the drive of the elastic element 220, drawing in air from outside the piston cavity 250 or expelling air from inside the piston cavity 250, thereby impacting the bottom cover 150 of the firework shell 10 with the expelled air. In this embodiment, the launching mechanism 20 applies an impact force to the ignition powder 140 of the firework shell 10 through air compression to ignite the ignition powder 140. Specifically, the launching mechanism 20 includes a launching tube 210, an elastic element 220 disposed within the launching tube 210, a piston 240, and a piston cavity 250. One end of the elastic element 220 is fixed to the inner wall of the launching tube 210, and the other end is connected to the piston 240. The diameter of piston 240 is slightly larger than or equal to the inner diameter of piston cavity 250 to better facilitate the air intake process. During the compression and resetting process of elastic element 220, piston 240 reciprocates within piston cavity 250 under the action of elastic element 220. When elastic element 220 is compressed, piston 240 moves away from firework shell 10 to draw in air from outside piston cavity 250. When elastic element 220 is reset, piston 240 moves towards firework shell 10 to expel air from piston cavity 250, which then impacts the bottom cover 150 of firework shell 10. Driven by compressed air, firework shell 10 is launched and simultaneously ignites gunpowder 140, causing an explosion and igniting inner shell 120 to achieve the effect of fireworks in the air.

[0034] Optionally, the inner wall of the launching tube 210 converges radially to form a vent 211, and the end of the piston cavity 250 away from the elastic member 220 protrudes outward to form a gas-gathering part 251, which is disposed within the vent 211. Specifically, in order to better fix the piston cavity 250 and prevent it from shifting within the launching tube 210 after air is drawn in, thereby affecting the firing effect of the firework shell 10, in the illustrated structure, the inner wall of the launching tube 210 converges radially to form a vent 211 for air circulation, and the end of the piston cavity 250 away from the elastic member 220 protrudes outward to form a gas-gathering part 251 with an outer diameter much smaller than the outer diameter of the piston cavity 250. The outer diameter of the gas-gathering part 251 is less than or equal to the inner diameter of the vent 211.

[0035] Please refer to Figure 5The launching mechanism 20 also includes a magazine 260 for loading the firework shells 10. The magazine 260 is mounted on and connected to the launching tube 210. Specifically, compared to traditional fireworks, this embodiment, based on the launching mechanism 20 described above, adds a magazine 260 connected to the launching tube 210, thereby increasing the capacity of a single firework shell 10 and significantly improving playability. For example, by changing the magazine 260 from a normal under-hand position to an inverted position (i.e., magazine 260 on top, launching tube 210 below), automatic loading of the firework shells 10 can be achieved by using gravity.

[0036] Please refer to Figure 3 , Figure 4 or Figure 5 The launching tube 210 has a firework shell receiving portion 212 for mounting the firework shell 10. The firework shell receiving portion 212 has a first part that connects to the piston cavity 250 or the impact head 230 and a second part for the firework shell 10 to slide along the opening direction of the launching tube 210. The magazine 260 is disposed on the first part. Specifically, as shown in the figure... Figure 3 In the structure shown, the location of the firework shell receiving part 212 is the area to the right of the impact head 230 inside the launch tube 210. The first part is the area covered when the firework shell 10 just touches the impact head 230, and the remaining area is the second part. Figure 4 or Figure 5 In the structure shown, the firework shell receiving portion 212 is located to the right of the piston cavity 250 (specifically, the vent 211) inside the launch tube 210. The first part is the area covered when the firework shell 10 just touches the vent 211, and the remaining area is the second part. In this embodiment, the magazine 260 is mounted on the first part to increase the kinetic energy gained by the firework shell 10, increase the flight time and distance of the firework shell 10, and improve playability.

[0037] Optionally, the launching mechanism 20 further includes a control unit (not shown) and a drive motor (not shown). The control unit (not shown) and the drive motor (not shown) are electrically connected. The drive motor (not shown) is disposed within the magazine 260 and is used to drive the firework shell 10 loaded in the magazine 260 to the first part of the launching tube 210 under the control of the control unit (not shown). Specifically, in one embodiment, the launching mechanism 20 further includes a control unit (not shown) and a drive motor (not shown), which can be connected by an electrical signal or by a wire, without limitation. The drive motor (not shown in the figure) is installed inside the magazine 260. In actual implementation, the user can control the operation of the drive motor (not shown in the figure) by operating the control unit (not shown in the figure). This allows the firework shell 10 currently located in the first part of the launch tube 210 to be fired, and then automatically loaded into the first part of the launch tube 210 by filling the magazine 260 with the firework shell 10, thus achieving automatic loading. Furthermore, the user can manually control the firing rhythm of the firework shell 10, achieving single shot, burst fire, and pause at any time, without needing to preset a fixed position or direction, greatly enhancing the fun and playability. In one embodiment, the control unit (not shown in the figure) can be a trigger. In other embodiments, a spring can be installed inside the magazine 260, and the firework shell 10 can be loaded by compressing and releasing the spring; this is not the only possible embodiment.

[0038] This application places an isolator with a through hole inside the outer tube, with the inner shell and igniter placed on opposite sides of the isolator. By applying an impact force to the end of the outer tube containing the igniter, the inner shell is detonated, thus forming a firework. No external fuse or open flame is required, making it less susceptible to weather interference and highly playable. The igniter and inner shell burn in a sequential manner, and the burning speed can be dynamically adjusted by changing the composition of the igniter, thereby delaying the detonation of the inner shell and avoiding the risk of tube explosion. Furthermore, by cooperating with the launching mechanism proposed in this application, users can manually control the launch rhythm of the firework shell. Compared with traditional fireworks, it has significant advantages in terms of playability, fun, safety, and ease of use.

[0039] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this invention should be included within the scope of protection of this invention. Therefore, the scope of protection of this invention should be determined by the appended claims.
