Abstract
The utility model discloses a firecracker, which comprises a firecracker body with an open end. The open end of the firecracker body is sealed through a hot shrinkage sheath; an air-inlet valve is arranged on the firecracker body; an ignition plug is further mounted in the firecracker body; a connecting end of the ignition plug protrudes outwards from the firecracker body and is connected with a power supply through a conducting wire; a sleeve gasket is mounted on the outer surface of the open end of the firecracker body; and the hot shrinkage sheath is sleeved on the outer side of the sleeve gasket. When people need to set off firecrackers, the firecracker body is filled with a certain proportion of hydrogen and air through the air-inlet valve, the power supply controls the ignition plug to strike sparks, and the sparks ignite the mixed gas, so that the hot shrinkage sheath sleeved on the outer side of the firecracker body is exploded due to the instantaneous gas explosion, and the noise is made. The firecracker generates moisture after being set off, and is safe and environment-friendly; and the hot shrinkage sheath sleeved on the outer side of the firecracker is damaged after explosion, the firecracker body can be repeatedly used, and the energy is saved.
Description
Technical field
The utility model relates to a kind of firecrackers, specifically is the firecrackers of a kind of safety, environmental protection.
Background technology
As everyone knows, traditional firecrackers mainly are to use and fill medicine in the paper web, sealing two ends, and at one end draw by lead-in wire.During this traditional firecracker setting-off,, blast, blow paper web, produce huge effects,sound by the fuse medicine that ignites.This kind firecrackers shortcoming in the process of setting off is: 1. this kind of burning medicine can produce a large amount of pernicious gases such as flue gas, the contaminated air environment; 2. after the blast, produce a large amount of shredded paper bits, cause environmental pollution.
The utility model content
The technical problems to be solved in the utility model provides the firecrackers of a kind of safety, environmental protection.
For solving the problems of the technologies described above, the firecrackers that provided, the firecrackers body that comprises an end opening, its design feature is: the openend of described firecrackers body seals by thermal shrinkable sleeve, the firecrackers body is provided with intake valve, spark plug also is housed in the firecrackers body, and the link of this spark plug stretches out firecrackers outward, and this is external and link to each other with power supply by lead.
After adopting said structure, because the openend of described firecrackers body seals by thermal shrinkable sleeve, the firecrackers body is provided with intake valve, spark plug also is housed in the firecrackers body, the link of this spark plug stretches out firecrackers outward, and this is external and link to each other with power supply by lead, when needs are set off firecracker, in the firecrackers body, feed a certain proportion of hydrogen and air by intake valve, get spark by power supply control spark plug, spark ignites mist, the gas burst of moment is collapsed the thermal shrinkable sleeve of firecrackers body outside suit broken, sends sound.This firecrackers only produce moisture, safety and environmental protection after setting off; And only damaged the thermal shrinkable sleeve of firecrackers body outside suit after the explosion, the firecrackers body can also reuse, and has saved the energy.
The outer surface of described firecrackers body open end is equipped with sealing shroud, and described thermal shrinkable sleeve is sleeved on the outside of sealing shroud.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is a structural representation of the present utility model;
The structural representation that Fig. 2 looks up for Fig. 1.
The specific embodiment
Firecrackers as depicted in figs. 1 and 2 comprise and the firecrackers body 1 of an end opening on one side of firecrackers body 1 intake valve 3 are housed that the structure of intake valve 3 is a prior art, repeats no more.The openend outer surface of firecrackers body 1 is equipped with sealing shroud 6, sealing shroud 6 seals by all-purpose adhesive with the lateral surface of firecrackers body 1, sealing shroud 6 outsides are set with the thermal shrinkable sleeve 2 that can seal up firecrackers body 1 openend, spark plug 4 also is housed in the firecrackers body 1, and terminal outer the stretching out outside the firecrackers body 1 and by lead of this spark plug 4 links to each other with power supply 5.The utility model several can also be connected on the order circuit, fix by the rope body, and package and form the big gun of ending a teaching or coaching career, after giving power on circuitry, all firecrackers can be switched on successively, and send explosion sound.
