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

[0028] Reference attached figure 1 , Place large bright beads 2 and small bright beads 3 with different volumes in the housing 4. The volume of the bright beads is different, and the time to burn and glow is also different. The light-emitting time is long when the volume is large, and the light-emitting time is short when the volume is small. The small bright beads 3 are placed in one shape in the casing 4, and the large bright beads 2 are placed in the casing 4 or combined with the small bright beads 3 to form another shape. When the projectile exploded in the air, the large and small bright beads were illuminated at the same time. First, it shows a shape, such as a spherical shape; after the small bright bead 3 is extinguished, the large bright bead 2 continues to burn and glow due to its large volume and burns for a long time, so a second shape of fireworks appears, such as a ring. The light-emitting time of the small bright bead 3 can be set as 3 seconds, and the light-emitti...

Embodiment 2

[0030] Reference attached figure 2 with image 3 , Place ordinary bright beads 5 and bright beads 6 composed of at least two layers of luminescent materials with different brightness in the housing 4, that is, a dark light method is adopted. For example, placing a green ordinary bright bead into a shape, such as a ring, in the housing. The burning time of the green ordinary bright bead is 5 seconds. Place the green double-layer bright beads in the shell or form another shape with ordinary green bright beads, such as a spherical shape. The burning and luminous time of the green double-layer bright bead 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 bead is dark light , Basically invisible color. The green ordinary bright bead is very bright green, which completely conceals the dark light of the green double-layer bright ...

Embodiment 3

[0045]The small projectiles and bright beads of different shapes or different colors or the same color are reasonably installed in a large projectile. Install the small projectile on the periphery of the large projectile, and install the bright bead near the center of the large projectile. When the large projectile explodes in the air to explode, the bright bead is ignited first, and the shape produced by the bright bead appears. At this time, the timing lead of the small projectile mounted on the periphery of the large projectile is ignited. When the bright bead burns and glows, the small projectile is detonated, showing another flower shape. For example, a large projectile of a peony shape, a chrysanthemum shape, a wheel shape, a large lotus shape, a coconut tree shape, a discoloration shape, etc., can be filled with other small projectiles. When a large projectile explodes in the air to display flowers, such as a peony shape, after the peony-shaped bright beads are all extingui...

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 firework bomb, in particular to a firework bomb with a deformation effect when displaying flowers in the air. Background technique [0002] The firework bomb is launched into the air by igniting the gunpowder in the launching tube. When the firework bomb reaches a predetermined height, the explosive gunpowder in the shell is ignited and exploded, igniting the bright beads and other contents and spreading them in the air, producing various firework effects. At present, the firework bombs produced at home and abroad are all single-shaped firework bombs, such as traditional varieties such as peony-shaped, chrysanthemum-shaped, dahlia-shaped, coconut tree-shaped, palm tree-shaped, round flower-shaped, color-changing shape, modeling and so on. These varieties are all one shot and one style. For example, a peony-shaped firework bomb is launched into the air to explode, and the bright beads contained in the bomb are shot out in the shape...
