Description
Technical field
The present invention relates to gas detonation field, particularly a kind of firecracker sounding and luminous gas sound-producing device of simulating.
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 city haze and increases the risk of 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 Englishman 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
Set off environment damage for reducing firecracker, save social resources, the present invention designs a kind of simulation firecracker.
The present invention realizes that the technical scheme that goal of the invention adopts is: a kind of simulation firecracker is characterized in that: by firecracker, leading post, air chamber, gas tube, fixedly circular hole, extension spring, leading circular hole, seal cover board, switch spring, power supply, LED lamp, switchboard and sealing rubber pad are formed; 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; Sealing rubber pad is arranged below the seal cover board, and the seal cover board fixedly circular hole of the end of fixing extension spring is down 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 the leading post; Be fixed with a magnetic clasp between two leading posts of the openend of firecracker, seal cover board is the soft magnetic materials that hard metal is formed, seal cover board is with the openend sealing of firecracker, after the long bolt screw of extension spring bottom passes the firecracker bottom circular aperture, pass through nut, seal washer is fixed and is sealed, for guaranteeing good sealing effectiveness, the part that screw rod is positioned at the firecracker air chamber has a rosette that expands with the screw rod all-in-one-piece, there is a rubber washer to be enclosed within on the screw rod between rosette and the firecracker bottom, the circular hole of packing ring is suitable with the long bolt diameter, and 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 fixed by nut switchboard of switchboard, switchboard is a hard plastic board, there is a metal switch spring centre of switchboard, and switch spring, power supply and LED lamp and seal cover board are formed series circuit.
A kind of using method of simulating firecracker, it is characterized in that: pump-up device is by the air chamber inflation of gas tube to firecracker, when 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 the leading post simultaneously, the contact-making switch spring, connection circuit, the LED lamp is lighted; When the pressure of air chamber equated with outside pressure, switch spring pushed away, extension spring draws seal cover board is sent back to, with the air chamber sealing, and while cut-off switch spring, circuit disconnects, and the LED lamp extinguishes; What continue inflates, and can produce explosion and light gradually, realizes the sound and the light of simulation firecracker.
The invention has the beneficial effects as follows: device is simple, and is 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, do not have risk in transit; Can be used as toy for children uses.
