Safe environmentally-friendly firecracker with two serially-connected built-in bodies

Abstract

The invention belongs to the technical field of firecrackers and particularly relates to a safe environmentally-friendly firecracker with two serially-connected built-in bodies, and the firecracker is used for solving the problem that an existing safe, environmentally-friendly and energy-saving firecracker has a limited sound number and has difficulty in building festival atmosphere brought by the traditional firecracker. The firecracker comprises a plurality of single bodies, wherein each single body comprises a connecting piece and a fixed leading plug; each connecting piece is of a cylindrical structure with one closed end; each fixed leading plug comprises a table body at one end and a cylinder at the other end, and each cylinder is integrated with the small-diameter end of the corresponding table body; the cylinder part of each leading plug is inserted into the cylindrical structure of each connecting piece; the table body part of each fixed leading plug is inserted into a metal shell respectively; and outer shells are sleeved outside the metal shells and the connecting pieces. The built-in safe environmentally-friendly firecracker has the following beneficial effects: zero discharge is basically realized, air pollution, dust pollution and potential safety hazards caused by the traditional firecracker are overcome to the greatest extent, the advantages of the traditional firecracker and the existing safe and energy-saving firecracker are combined, and safety, environmental friendliness and energy conservation are realized to a greater extent.

Description

technical field [0001] The invention belongs to the technical field of firecrackers, and in particular relates to a double-body serial built-in safety and environmental protection firecracker. Background technique [0002] The hazards of traditional firecrackers to people's lives are well known, such as serious air pollution, dust pollution, fires and possible personal injury to those who set off firecrackers and onlookers. [0003] Chinese patent 200610012596.2 safety, environmental protection, energy-saving built-in firecrackers, and Chinese patent 200610012598.1 safety, environmental protection, energy-saving built-in firecrackers. These two kinds of firecrackers have completely changed the sound effect generation principle of traditional firecrackers. When they are set off, they do not produce any discharge residue, which saves all kinds of manpower and material resources for cleaning the residue, and there is no hidden danger of harming the discharge and onlookers.
