A combined flute sound firecracker

Abstract

The invention discloses combined whistling firecracker. A plurality of different cracking sounds can be simultaneously obtained during burning, and the combined whistling firecracker is relatively simple in structure, simple in processing and manufacturing technology, convenient, safe and relatively low in manufacturing cost. The combined whistling firecracker comprises a barrel, a whistling barrel, gunpowder, a leading wire and sealed materials, wherein corresponding fire holes are formed in a baseboard on one sealed end of the whistling barrel, the barrel comprises an outer barrel and an inner barrel which is arranged inside the outer barrel, the inner barrel and the whistling barrel are respectively provided with the powder, the whistling barrel is arranged inside the outer barrel, the outer barrel, the inner barrel and the whistling barrel are respectively discrete pieces, and the leading wire is connected to the whistling barrel.

Description

technical field [0001] The invention relates to a firecracker, in particular to a combined flute sound firecracker. Background technique [0002] Firecrackers are a traditional product with a long history, a festive product, and also a kind of propaganda and information transmission product. However, both the production process and product structure of firecrackers are consistent with its development. Change, because this single structural mode determines its single sound. And the existing so-called flute firecrackers that can improve the sound proposed at this defect, its structure and its manufacturing method all have deficiency in varying degrees, as the technological step of making is multifarious, production efficiency is low, and manufacturing cost is high, Especially because the technological process of making is very long and complicated, the operation time and steps are more under the situation that gunpowder is arranged, so that there are many hidden dangers in th...
