Problems solved by technology

[0002] At present, most of the known fireworks and firecrackers are equipped with a gunpowder fuze or a backup fuse of the same kind to set off fireworks and firecrackers. When setting off, most of them are set off by using an open flame or an external igniter to ignite the powder fuze. Their disadvantages are There are many unsafe factors and inconvenient operation, especially when the first gunpowder fuze of fireworks and firecrackers fails to detonate fireworks and firecrackers, and the backup fuze is lit with an open flame

specific Embodiment approach 2

[0018] The gunpowder fuze (6) and the heating fuze (4) of fireworks and firecrackers (5) are as image 3 Connected together as shown, the heating wire (2) of the heating fuze (4) is connected on the middle section of the gunpowder fuze (6), and the heating fuze (4) and the gunpowder fuze (6) form a connection point (10), at the connection point (9) also has a section of gunpowder outer fuze (3) remaining outside, and when setting off, both can choose to directly ignite the gunpowder outer fuze (3) by open flame and can choose to ignite by heating fuze (4).

specific Embodiment approach 3

[0019] Such as Figure 4 As shown, the heating fuze (4) is directly connected with the internal propellant (7) of the fireworks (5) to form a double-fuze fireworks and firecracker with both an electric heating fuze (4) and a gunpowder fuze (6). , and then respectively weave the powder fuzes (6) of a plurality of double-fuze fireworks and firecrackers together to form the powder fuze combustion connection ignition end, and electrically connect the electric heating fuze power supply terminals (8) of the double-fuze fireworks and firecrackers together to form a common power supply terminal Leads to the power supply control box. When lighting fireworks and firecrackers, both the gunpowder fuze can be ignited by an open flame and the internal pyrotechnic fuze (7) can be ignited to set off by the heating fuze (4).

Abstract

The invention relates to a fireworks and firecrackers, in particular to a safe ignition fireworks and firecrackers with electric heating fuze or with powder fuze and electric heating fuze and a manufacturing method thereof. Heating material fuze is directly connected to the powder of the fireworks and firecrackers through the powder fuze or through no powder fuze. After the single fireworks and firecrackers with the electric heating fuze or with the electric heating fuze and powder fuze, a long metal conducting wire is connected to a power supply operation control box by the heating material fuze of the fireworks and firecrackers through connecting points. When the bunchy fireworks and firecrackers are spliced, the electric heating material fuzes of the fireworks and firecrackers are respectively connected to the power supply control box, and the powder fuzes are spliced together along the arranged firecrackers, or the heating material of the heating fuze is connected to the powder fuzes of the fireworks and firecrackers or the naked flame igniting ends of the powder fuzes of the bunchy firecrackers, and a section of powder fuze is also remained outside the connecting points.

Description

Technical field [0001] The present invention relates to a kind of fireworks and firecrackers, especially fireworks and firecrackers with electric heating fuze or simultaneously with gunpowder fuze and electric heating fuze. A method for manufacturing fireworks and firecrackers with electric heating fuzes. Background technique [0002] At present, most of the known fireworks and firecrackers are equipped with a gunpowder fuze or a backup fuse of the same kind to set off fireworks and firecrackers. When setting off, most of them are set off by using an open flame or an external igniter to ignite the powder fuze. Their disadvantages are There are many unsafe factors and inconvenient operation, especially when the first gunpowder fuze of fireworks and firecrackers fails to detonate fireworks and firecrackers and goes to light the spare fuze with open flame. Contents of the invention [0003] The object of the present invention is to provide an electric heating fuze which is r...
