Abstract
The utility model discloses a new-type firecracker. The utility model is formed by that a plurality of air bag firecrackers are connected in series by conducting wires so as to form the firecracker. The detonation of the utility model is controlled by an electric heating device and a reversing switch. The utility model has the advantage of no existence of powder in the whole process of detonation so that all the side effects generated when the existing gunpowder firecrackers are set off are eliminated.
Description
The utility model is a kind of improved firecrackers.
As everyone knows, existing firecrackers are made up of gunpowder firecracker, blasting fuse, skeleton line, but because of its in dispose procedure, can produce a large amount of pollutants, human body and natural environment are produced harm, and can cause fire, so this kind firecrackers are forbidden to put in present more and more countries and city, but people be can't do without fireworks again in the celebrating date.
The purpose of this utility model provides a kind of pollution-free, can not cause fire, and human body and natural environment are no longer produced the firecrackers design of harm.
The purpose of this utility model is achieved in that the Air sac firecracker that several are made up of air bag, shell, by the lead formation firecrackers that are together in series, is provided with the decompression louver on the shell of each Air sac firecracker.In the shell of each Air sac firecracker, be provided with air bag and ignite the electric heater of usefulness, one of electric heater by leading directly to lead and extremely linking to each other being connected with one of power supply of common wire, reversing switch is passed through in the other end of electric heater, lead and power switch are connected with another utmost point of power supply, constitute electric loop, the reversing switch contact net is by a main contacts, two branch contacts are formed, main contacts passes through lead, power switch is connected with a utmost point of power supply, in two branch contacts, first fen contact is the make contact of this utmost point electric heater circuit, second fen contact is the make contact of next stage electric heater circuit, when setting off firecrackers, as long as power switch is closed, connect the electric heater circuit of the first order, electric heater heats to air bag, when reaching the temperature of air bag blast, the air bag blast, gases at high pressure and sound discharge from the decompression louver that is located on the Air sac firecracker shell.Reversing switch cuts off the circuit of electric heater at the corresponding levels automatically, connects the circuit of next stage electric heater simultaneously, and above-mentioned several processes couple together and just formed the firecrackers effect.
Below with reference to accompanying drawing the utility model is described in further detail:
Fig. 1 is the part cross-sectional schematic of a kind of concrete structure of the utility model.
Among Fig. 1: 1. straight-through lead, 2. common wire, 3. power supply, 4. power switch, 5. main contacts, 6. first fen contact, 7. electric heater, 8. air bag, 9. shell, 10. interconnecting lead, 11. Air sac firecrackers, 12. second fens contacts, 13. reversing switches, 14. leads, 15. decompression louvers.
As seen from Figure 1, several are by air bag 8, shell 9, the Air sac firecracker 11 formed, by common wire 2 and interconnecting lead 10, the effect formation firecrackers that are together in series, on the shell 9 of Air sac firecracker 11, be provided with decompression louver 15.In the shell 9 of Air sac firecracker 11, be provided with air bag 8 and ignite the electric heater 7 of usefulness, one of electric heater 7 is connected with a utmost point of power supply 3 with common wire 2 by straight-through lead 1, the other end of electric heater 7 is connected with first fen contact 6 of reversing switch 13, and main contacts 5, lead 14, power switch 4 by reversing switch 13 are connected with another utmost point of power supply 3, constitute electric loop.Reversing switch 13 contact nets are made up of a main contacts 5 and two branch contacts (6) (12), main contacts 5 is connected with a utmost point of power supply 3 by lead 14 and power switch 4, first fen contact 6 is the circuit make contact of electric heater 7 at the corresponding levels, and second fen contact 12 becomes the circuit make contact of next stage electric heater by interconnecting lead 10.When setting off firecrackers,, the circuit of first order electric heater is connected as long as power switch 4 is closed, electric heater 7 just gives air bag 8 heating, when reaching the blast temperature of air bag 8, air bag 8 blasts, gases at high pressure and sound discharge from the decompression louver 15 that is located on the Air sac firecracker shell 9.Reversing switch 13 cuts off the circuit of electric heater 7 automatically, and by dividing contact 12 and interconnecting cable 10 that the circuit of the electric heater of next utmost point is connected, above-mentioned several processes couple together and just formed the firecrackers effect simultaneously.
The utility model has the advantage of, the existence of no gunpowder in whole ignition process, and then All side effects that existing gunpowder firecrackers produce have been eliminated when setting off.
Claims (3)
1. novel firecrackers is characterized in that: several are by air bag, the Air sac firecracker that shell is formed, couple together the formation firecrackers by lead, in the shell of each Air sac firecracker, be provided with air bag and ignite the electric heater of usefulness, one of electric heater is connected with a utmost point of power supply with common wire by straight-through lead, and the other end is connected with another utmost point of power supply by reversing switch, lead, power switch, constitutes electric loop.
2. it is characterized in that by the described a kind of novel firecrackers of claim 1: the contact net of reversing switch, form by a main contacts, two branch contacts, main contacts is connected with a utmost point of power supply by lead, power switch, the circuit make contact that first fen contact is electric heater at the corresponding levels, second fen contact becomes the circuit make contact of next stage electric heater by interconnecting lead.
3. it is characterized in that by the described a kind of novel firecrackers of claim 1: on the shell of each Air sac firecracker, be provided with the decompression louver.
