Abstract
The invention relates to an imitated firecracker, belongs to the field of gas bursting and sounding, and particularly relates to a gas sounding device imitating sounding and lighting of a firecracker. The firecracker brings to worsening of air quality and risks like fire disasters, human body injuries, and architecture collapse. The imitated firecracker aims to reduce damage to the environment caused by burning of the firecracker and save social resources. The technical scheme is that a gas cavity of a firecracker barrel is inflated by an inflation device through an inflation pipe; when the pressure of the gas cavity reaches 1.5* 1.01*105Pa-2.0* 1.01*105Pa, the tension force of an extension spring and the magnetic field force of a magnetic buckle are overcome by the pressure of gas, a sealing cover plate is opened, sounding is generated, and meanwhile the sealing cover plate moves along a guide pillar and contacts a switch spring to connect a circuit, and a light-emitting diode (LED) light is lighted up. The imitated firecracker has the advantages of being simple in device, low in cost, and capable of being circularly used, generating firecracker sounding and imitating firelight, can not produce pollutant and fire risks, can not damage architectures, has no transportation risks, and can be used as a child toy.
Description
Technical field

Background technology
On New Year's Day or other festivals, it is celebrating lively that the people like, like setting off firecrackers, but the concentrated short time of firecracker sets off, the deterioration that the smell of firecracker and the powder of firecracker bring air quality, the urban air-quality that this has been worsened is brought and is made the matter worse, and increases the weight of the risk of city haze and increase breathing problem; The setting off of firecracker also may be brought fire, personal injury, the building equivalent risk that collapses; Firecracker is long at Chinese history, gunpowder is one of four invents by China, but Chinese utilize gunpowder to make firecracker, and Englishmen etc. utilize gunpowder to make firearms plunder China wealth, this history can not be forgotten, the too much burning of firecracker can only be to endanger the realm to hinder the people, is a kind of waste of social resources.
Summary of the invention
For reducing the destruction of firecracker setoff to environment, save social resources, the present invention designs a kind of simulation firecracker.
The technical scheme that the present invention realizes goal of the invention employing is: a kind of simulation firecracker, is characterized in that: be made up of firecracker, leading post, air chamber, gas tube, fixing circular hole, extension spring, leading circular hole, seal cover board, switch spring, power supply, LED lamp, switchboard and sealing rubber pad, a circular hole is arranged at the bottom of firecracker, and there is a gas tube side, and seal cover board is arranged at top, below seal cover board, have sealing rubber pad, under seal cover board, the fixing circular hole of the end of fixing extension spring is worn a long bolt screw, and the long bolt of screw passes from the circular hole of firecracker bottom, and the leading circular hole of seal cover board is inserted in leading post, between two leading posts of the openend of firecracker, be fixed with a magnetic clasp, seal cover board is the soft magnetic materials of hard metal composition, seal cover board is by the openend sealing of firecracker, the long bolt screw of extension spring bottom passes after firecracker bottom circular aperture, pass through nut, seal washer is fixed and is sealed, for ensureing good sealing effectiveness, the part that screw rod is positioned at firecracker air chamber has a rosette expanding with screw rod all-in-one-piece, between rosette and firecracker bottom, there is a rubber washer to be enclosed within on screw rod, the circular hole of packing ring is suitable with long bolt diameter, the diameter of packing ring is than the little 8-10mm of rosette diameter, leading post end has screw thread, switchboard has circular hole, and by circular hole, leading male screw, the nut floatless switch plate of switchboard, switchboard is hard plastic board, there is a switch spring centre of switchboard, switch spring, power supply and LED lamp and seal cover board composition series circuit.
A kind of using method of simulating firecracker, it is characterized in that: pump-up device is the air chamber inflation to firecracker by gas tube, in the time that the pressure of air chamber reaches 1.5-2.0 atmospheric pressure, gas pressure overcomes the pulling force of extension spring and the magnetic field force of magnetic clasp, and seal cover board is opened, and sends explosion, seal cover board moves to switchboard along leading post simultaneously, contact-making switch spring, connection circuit, LED lamp is lighted; In the time that the pressure of air chamber equates with outside pressure, switch spring pushes away, extension spring draws seal cover board is sent back to, by air chamber sealing, and cut-off switch spring simultaneously, circuit disconnects, and LED lamp extinguishes; What continue inflates, and can gradually produce explosion and light, realizes the sound and the light of simulation firecracker.
The invention has the beneficial effects as follows: device is simple, with low cost; Device can recycle, and saves social resources; Can produce the firecracker sound and simulation flame, not produce any pollutant; Do not have fire risk, can not damage building, there is no risk in transit; Can be used as toy for children uses.
