Device for displaying small-size caption-pattern fireworks

Abstract

The invention discloses a device for displaying small-size caption-pattern fireworks, which comprises a basal plate provided with a plurality of jacks, the jacks are arranged on the basal plate according to caption-pattern contents, axial lines of the jacks are inclined to a plane where the basal plate locates, the inclination directions of the jacks all point to the stroke direction of characters or the line direction of patterns, effect powders are directly arranged in the jacks, or effect cartridges containing fireworks are arranged in the jacks, and the effect powders or the effect cartridges in the jacks are connected by an ignition device. As the inclined jacks are arranged on the basal plate, fireworks jetted from all jacks are connected end to end and mutually jointed together to form continuous strokes or lines without breakpoints; the contents of characters or patterns to be expressed can be displayed definitely even if a person watches at a nearer distance; and meanwhile, the invention adopts an ignition slot so as to avoid the burning effect interference and the potential safety hazard caused by lead-wire burning.

Description

technical field [0001] The invention relates to the field of fireworks, in particular to a small-sized or indoor fireworks with subtitle patterns. Background technique [0002] At present, there is a firework with a subtitle pattern, which can present subtitles or patterns according to the user's needs when it is set off, and is very popular among users. However, the existing mature technologies are suitable for large-scale products, and cannot meet the needs of smaller-scale discharges, which limits the application of marquee fireworks. Although there are also some researches on small subtitle fireworks, such as a kind of subtitle miniature fireworks disclosed by CN2615630 that can be arranged and plugged at will, portable subtitle graphics fireworks disclosed by CN2856916, a kind of miniature subtitle fireworks disclosed by CN1444007, etc., in its structure The common feature is that a plurality of fireworks are vertically fixed side by side in the vertical holes on the s...

However, the existing mature technologies are suitable for large-scale products, and do not meet the needs of smaller-scale discharges, which limits the application of marquee fireworks.

Although there are also some researches on small subtitle fireworks, such as a kind of subtitle miniature fireworks disclosed by CN2615630 that can be arranged and plugged at will, portable subtitle graphics fireworks disclosed by CN2856916, a kind of miniature subtitle fireworks disclosed by CN1444007, etc., in its structure The common feature is that a plurality of fireworks are vertically fixed side by side in the vertical holes on the substrate according to the required shape or pattern, and the flames sprayed by each firework are sprayed vertically upwards when setting off, and the strokes or lines are formed by discontinuous lines when subtitles or patterns are formed. Composed of light spots, when viewed indoors or at a close distance, the breakpoints in its strokes or lines are very obvious, which seriously affects the effect. When the subtitles or patterns are more complicated, the existing small subtitle fireworks cannot express their content at all

At the same time, the existing products all use lead wires to ignite, and the ignition lead itself burns and emits light that destroys the shape of the subtitle pattern, especially when it is close indoors; at the same time, lead slag falling on the indoor floor may easily cause safety hazards
