Problems solved by technology

For example, peony-shaped fireworks shells, from lighting up to completely extinguishing, the bright beads appear in a spherical shape until they are extinguished in a spherical shape, that is, a bomb explodes and displays only one shape, which is relatively monotonous

Embodiment 1

[0027] Refer to attached figure 1 , place large bright beads 2 and small bright beads 3 with different volumes in the housing 4 . The volume of bright beads is different, and the time of burning and glowing is also different. The larger the volume, the longer the luminous time, and the smaller the luminous time is. Put the small bright beads 3 in the housing 4

[0028] Set into a shape, place the big bright bead 2 in the housing 4 or form another shape with the small bright bead 3. When the projectile explodes in the air and displays flowers, the large and small bright beads are lit simultaneously. First show a shape, such as spherical; after the small bright bead 3 is extinguished, the big bright bead 2 burns and emits light for a long time because of its large volume, and still continues to burn and emit light, so there is a second type of fireworks, such as a ring. The luminous time of the small bright bead 3 can be set as 3 seconds, and the luminous time of the big bri...

Embodiment 2

[0030] Refer to attached figure 2 with image 3 1. Place the common first unit bright beads 5 and the second unit bright beads 6 made of at least two or more layers of luminescent materials with different brightness in the housing 4, that is, adopt the dark light method. For example, green ordinary bright beads are placed in a shape, such as a ring, in the shell. The burning and glowing time of green ordinary bright beads is 5 seconds. Place the green double-layer bright beads in the shell or form another shape with the green ordinary bright beads, such as spherical. The burning and luminous time of the green double-layer bright beads is also 5 seconds, but the burning and luminous time of the outer layer of luminescent material 8 is 2 seconds, and the light emitted is dark light, that is, the first 2 seconds of the green double-layer bright beads are dark light , basically invisible color. The green ordinary bright beads are very bright green, which completely covers up ...

Embodiment 3

[0045] Small elastic bodies and bright beads of different shapes or different colors or the same color are reasonably installed in a large elastic body. Install the small elastic body on the periphery of the large elastic body, and install the bright beads near the center of the large elastic body. When the large projectile explodes in the air, the bright beads are first ignited, and the shape produced by the bright beads appears. At this time, the timing fuse of the small projectile body that is contained in the periphery of the large projectile body is ignited. When the bright bead stops burning and glowing, the small projectile is detonated, showing another flower shape. For example, in the large body of peony shape, chrysanthemum shape, wheel shape, big lotus shape, coconut tree shape, discoloration shape etc., pack the small body of other shapes again. When the large projectile explodes in the air, such as a peony, and after all the peony-shaped bright beads are extingu...

Abstract

An improved fireworks shell consists of a propellant powder, quick powder trains, a shell, explosive therein, bright beads, and a timing train connected with explosive and propellant powder at its both ends respectively. The quick powder trains are connected with electric detonators, which consist of training fuses, wires, electric powers and switches. Compared with prior arts, it is fired in a static ignition, so that no dead shell occurs. It has high reliability and simple structure, and costs low.

Description

technical field [0001] The invention relates to a display shell, in particular to a display shell with deformation effect when displaying flowers in the air. Background technique [0002] Firework shells launch the projectile into the air by igniting the propellant powder in the launch tube. When the fireworks bomb reaches a predetermined height, the explosive powder in the shell is ignited and explodes, ignites the bright beads and other contents and spreads them in the air, producing various fireworks effects. At present, the fireworks bombs produced at home and abroad are all of a single shape, such as traditional varieties with peony shape, chrysanthemum shape, dahlia shape, coconut tree shape, palm tree shape, wheel flower shape, color-changing shape, modeling and so on. These varieties are all one bomb and one shape. For example, a peony-shaped fireworks bomb is launched into the air to explode, and the bright beads contained in the bomb are shot out in a spherical s...
