Description
Technical field
Fireworks are the utility model is related to, more particularly, to fireworks inner tank.
Background technology
Traditional fireworks are formed by some paper web lead Series Packages equipped with medicine, and its formation is general all
To pass through cylinder processed, pressure mud bottom, insert draw, powder charge（Propellant powder and effect medicine etc.）, and most process is completed by manually,
Low production efficiency is not only existed, production cost is high, and unstable product quality, and using effect is bad, and potential safety hazard is more, simultaneously
A large amount of ecological resources are also consumed, are unfavorable for environmental protection.With constantly bringing forth new ideas for technology, people start to develop a kind of incite somebody to action
Medicine forms sub warhead in paper web, then sub warhead is individually placed in the outer barrel on launcher, using repeating back
Next constantly realize of the launcher utilized is received continuously to set off fireworks.Fireworks inner tank is placed in the outer barrel on launcher at present, and it is all
It is to open quick-fried medicine by what the lead lighted on launcher made inner cylinder（Or propellant powder）Burning produces air pressure impulse force and rises up into effect medicine
In the air, and combustion wire is put, effect medicine is seted off after aerial certain altitude is risen up into, produced spark and sound in the air, realize cigarette
Flower is seted off.But current fireworks inner tank there is problems in use, it is connected first, fireworks inner tank is both provided with greatly sealing
Cover（For safety and ensure that medicine is non-hygroscopic gets damp）, the easy monoblock type of the cover separates with cylinder and with making bright pearl liter
Sky, cause to be plastics cover everywhere with setting off, be unfavorable for environmental protection；Second, fire hole and steam vent in inner cylinder igniting pedestal
It is separated, improves die manufacturing cost and assembling combination expense, add production cost.
Utility model content
For above-mentioned the problems of fireworks inner tank in the prior art, the utility model provides a kind of not only structure letter
It is single, easily manufactured, and can ensure that sealing, can make again cover effect medicine open it is quick-fried before in the straight-through ignition type fireworks that burst into fragments
Cylinder.
The technical problems to be solved in the utility model is adopted the technical scheme that：The straight-through ignition type fireworks inner tank bag
Cylinder, cover and cylinder bottom are included, interior annular is provided with the cylinder, interior annular is connected with cylinder, has air-flow among interior annular
Chamber, the air flow chamber top are provided with ignition charge, and propellant powder is provided with ignition charge, effective medicine is set on propellant powder, along cylinder
Wall is axially opposing in vivo is provided with the lead that can connect propellant powder and effect medicine, and fire hole, cylinder bottom are provided among the cylinder bottom
On be provided with flange, the cylinder bottom is engaged with cylinder by flange fastening, and the fire hole is connected with air flow chamber, the cylinder
Lid is made of plastic sheet, and cylinder upper end is provided with bulge loop, and boss is provided with cover, by bulge loop and boss coordinate can cylinder with
Cover realizes that fastening is connected.
The utility model compared with prior art, has advantages below：First, using bulge loop and convex between lid and cylinder
Platform is pressed into mutual tight fit, can make to realize that sealing and connection are reliable between cylinder and lid before setting off, lid when setting off beginning
Crushed by gas pressure, will not overall separation and with bright pearl go up to the air and descend slowly and lightly, be advantageous to environmental protection；It is second, straight on cylinder bottom
Connect and be provided with middle fire hole and communicated with air flow chamber, after starting igniting, fire hole can as steam vent and with the gas on base
Discharge orifice is communicated, and thermal current is input in an other fireworks inner tank and realizes that igniting is seted off, has both simplified base mould structure, again
Delayed firing can be realized, it is ensured that lift-off medicine（Bright pearl）Delayed exploding, make to set off more rationally, color bursts forth more obvious.
Brief description of the drawings
Fig. 1 is main cross section structure diagram of the present utility model,
