Description

Electronic fire cracker

The utility model is a kind of sound that firecracker is seted off and can use repeatedly, light, mechanical, electrical device of simulating.

As everyone knows, commercially available most firecrackers are mainly made by explosive at present, and explosion time can produce a large amount of harmful smog and chip, not only contaminated environment influences health, improperly also can damage people, animal if set off, even cause fire, cause the loss of property, also can exhaust substantial contribution simultaneously, the only annual Spring Festival, China has just spent more than one hundred million units and thousands of, ten thousand accidents has taken place because of setting off firecrackers in a large number, for this reason, China forbids setting off firecrackers when having expressly provided the Spring Festival in some cities, and Offenders will be prosecuted.In order to be fit to China's national situation and folkways and customs, the portions of electronics firecracker appears on the market, as obtaining " electronics firecracker " (90215747.9) of utility model patent, it can only simulate lighting of firecracker, blast and flash of light, main utilization record has the tape and the playback head of the firecracker blast sound to pick up this audible signal, promote that loudspeaker and the complicated transmission device of a cover are formed sound system and by flash lamp and aim at the spot light lamp bulb and the lifting light source dish in firecracker hole through sound amplifying circuit, the flash system that transmission device is formed is simulated the blast and the flash of light of firecracker, complex structure not only, and the lively atmosphere when still not reaching firecracker and setting off.

The utility model is intended to design a kind of harmless to people, animal, property, Environmental security, and can simulate the overall process that firecracker is seted off realistically: sound, the light, mechanical, electrical device that light, explode, flash of light, smog can be used again repeatedly.

The utility model is fully to prove manufacturing feasibility, designs after the economy of use and the verisimilitude thereof.Fig. 1 is a structure chart of the present utility model, its shell is made up of end cover, cylindrical shell, overhead guard three parts, installing plate (4) is arranged at the bottom of end cover (3), the block switch (10) that is fixed with slowspeed machine (12) on it, reaches by its drive links to each other with attaching plug (1) with power transformer (14) and through power line, the intrinsic backing plate in top (5) of end cover (3), be fixed with control circuit board (2) and flash lamp and speculum (13) thereof on it, igniter fuse (17) and igniting trigger (16) also are equipped with in end cover (3) outside; Have a plurality of holes (21) on all directions of shell middle cylinder (19), in order to the flash of light that sees through flash lamp with pass lead to hang simulation firecracker (6), the size of simulation firecracker, shape is similar to true firecracker, an optical fiber (11) is passed at simulation firecracker front end center, the end of optical fiber scribbles the red clear dope that enlarges scattering, to simulate the sight that firecracker is lighted, the end of simulation firecracker is equipped with and drives block switch (10) by slowspeed machine (12) and control that it is bright, the optically focused miniature bulb (8) that puts out, connect by lead between each optically focused miniature bulb, the hole that lead passes on the tube is connected with power supply with control circuit board, the middle part inside out of cylindrical shell is equipped with loudspeaker (9), the top of cylindrical shell is fixed with a dividing plate with holes (15), be fixed with foraminate garden, bottom tube on it, a Dewar bottle of adding a cover (7) is housed in the tube of garden, fills solid carbon dioxide (dry ice) in the bottle, bottle cap is finished out by pulling draw ring (23), the smog system of closing is in order to make smog; Aperture is arranged at the bottom of overhead guard (18), passes lead in the hole, is hung with some simulation firecrackers, and top cover (20) is arranged at overhead guard top, and handle (22) is housed on it, so that hang the utility model.The end cover of shell, cylindrical shell, overhead guard three parts tighten up connection with screw.The block diagram of control circuit board such as Fig. 2, its circuit diagram such as Fig. 3, it is that output by sensor links to each other with the input of trigger, its output one tunnel triggers indication with igniting and links to each other, one the tunnel links to each other with delay controller, the output of delay controller links to each other with power supply, the input of timer links to each other with power supply, its output one tunnel connects slow-speed motor and drives block switch control and ignites and glisten, another output of timer respectively with sound system, the acousto-optic trigger, flash system three links to each other, and exports a signal and pass to compositions such as flash system control flash of light by the acousto-optic trigger when sound system sends the sound; Its sound system is that the output by the programmable storage (EPROM) that is solidified with the firecracker blast sound links to each other with the input of preamplifier, and its output links to each other with the input of power amplifier, and the output of power amplifier and the pin of loudspeaker are connected to form.

The course of work of the present utility model is: attaching plug inserts the 220V power supply, when lighting igniter fuse, it is shinny that igniting triggers the light emitting diode of indicating, sensor produces a signal by trigger and send delay controller, postpone timer switch closure after 2～3 seconds, complete machine enters the rotation of duty slowspeed machine and drives block switch, connect the power supply circuits of the optically focused miniature bulb in the simulation firecracker one by one, the optically focused miniature bulb will glimmer one by one, its terminal bottom optical fiber sends ruddiness, the sight when lighting with the simulation firecracker; Sound system work makes EPROM output firecracker audible signal, and output one tunnel promotes power amplifier after preposition amplification, and makes loudspeaker send the firecracker sound, and its sound intensity is controlled at below the noise intensity of regulation by potentiometer; The thresholding circuits for triggering are delivered on another road of firecracker audible signal after preposition amplification, trigger the controllable silicon conducting, the flasher circuit discharge, flash lamp penetrates the blast flash of light synchronous with the strong sound, flash of light is through mirror reflects, pass the cylindrical shell aperture, the directive space outerpace is with the sight of simulation firecracker explosion time flash of light; Upwards spur draw ring simultaneously and open the Dewar bottle cap, emit drikold is put smog with simulation firecracker explosion time sight.The complete machine working time is controlled by timer, generally about 1 minute, shuts down thereafter, covers Dewar bottle, and complete machine enters the triggering state for the treatment of once more, repeats said process, and the electronics firecracker can use repeatedly.

The utility model can be simulated the overall process that firecracker is seted off more realistically: lights, explodes, current intelligence such as flash of light, smog, and not only free from environmental pollution, and simple in structure, safe and reliable, can use repeatedly, economize on resources, reach lively atmosphere.
