CN2276828Y - Electronic firecrackers with sound, light and smoke - Google Patents

Abstract

The utility model relates to an electronic product simulating the physical characteristics of a firecracker from the external appearance and in the aspects of sound, light, and smoke. The utility model is formed by that a firecracker with a cylindrical external shape is formed by injection moulding by plastics; an electroacoustic device is used for the simulation of the sound of a firecracker; a sound-controlled converter is used for enabling the electronic firecracker to emit flashing light with the strength which is corresponding to the magnitude of sound; meanwhile, smoke spreads out of the dlectronic firecracker. As a result, the physical characteristics of a firecracker are simulated from the external appearance and in the aspects of sound, light, and smoke. The utility model has the advantages of repeatable use and capability of being used as both a decorative article and a high-grade toy.

Description

A kind of have sound, light, the electronic firecracker of cigarette

The utility model is a kind of from the electronic product of the physical features of harmony, light, cigarette aspect Simulation firecracker in appearance.

As everyone knows, firecrackers are that people represent celebrating articles for use in social activities, but it destroys environment, causes some harm.The utility model is a kind of chief of the big gun of flipping the whip, and wards off its short articles for use of new generation.

Scheme of the present utility model is: with plastic injection-moulded the one-tenth suitably hollow cylinder and the rib body of size one by one, in the part hollow shell, acoustic control flash lamp and sounding are housed, the parts of being fuming, these cylinders are connected into firecracker shape.Produce firecrackers sound, the adjustable size of firecrackers sound with integrated circuit and peripheral circuit.Flash lamp sends the flash of light that changes with a little less than the firecrackers sound intensity.In the part of being fuming, a storage box of depositing edible oil is arranged, one section tungsten filament places box outer near the lower bottom part place, the cotton thread group that is soaked with edible oil of drawing in the storage box is wrapped on the tungsten filament, when electric current by tungsten filament, the tungsten filament heating, the edible oil around it is heated, the light blue or green cigarette of emerging is with the smog of this Simulation firecracker explosion time.The physical features of firecrackers has been simulated in harmony, light, cigarette aspect so in appearance.

The utility model technology is simple, can use repeatedly, also can be used as adornment and high-grade toy.

Accompanying drawing has provided an embodiment of the present utility model.

Fig. 1 is the schematic appearance that realization has the electronic firecracker embodiment of sound, light, cigarette.

Fig. 2 is circuit theory diagrams of realizing firecrackers sound.

Fig. 3 is circuit theory diagrams of realizing flash of light.

Fig. 4 is a structural representation of realizing the smog part.

Wherein: 1 forms the plastic casing of electronic firecracker.The shell of 2 dress sounding parts.

The shell of 3 dress luminous components.4 adorn the shell of the parts of being fuming.

5 voice integrated packages (LSD2283).6 transistors.

7 transistors.8 transistors.

9 loudspeakers.10 button switches.

11 power supplys for integrated package work.12 diodes.

13 electric capacity.14 piezoelectric ceramic pieces.

15 transformers.16 audio frequency amplification circuits (LM386)

17 bulbs.18 thyristors.

19 power supplys for bulb and tungsten filament work.20 tungsten filaments.

21 storage boxes.22 cotton thread groups.

In Fig. 2, when button switch 10 was pressed, transistor 6 and 7 electronic switches of forming became conducting by ending, and entire circuit is started working.Power supply 11 is given voice integrated package 5 (LSD2283) power supply through transistor 7, and its output signal is divided into two-way, and one the tunnel promotes loudspeaker 9 playbacks after transistor 8 amplifies, send firecrackers sound; Another road output signal adds to the base stage of transistor 6 behind diode 12 and electric capacity 13 rectifying and wave-filterings, when button switch 10 disconnects, still keep the conducting of transistor 6 and 7.Like this, have only after one section firecrackers sound is intact, i.e. during voice integrated package 5 no signals output, transistor 6 and 7 just ends, and cuts off the electricity supply, and circuit is quit work.

In Fig. 3, when piezoelectric ceramic piece 14 receives firecrackers sound, audio frequency amplification circuit (LM386) 16 amplifies its audio signal, this signal makes thyristor 18 conductings through transformer 15, in the circuit that power supply 19 and bulb 17 grades are formed, its current strength is subjected to the control of thyristor, so bulb 17 is along with bright back light light is sent in the power variation of firecrackers sound.Tungsten filament 20 also is energized heating simultaneously.

In Fig. 4, place the cotton thread group 22 of storage box 21 to be splashed into edible oil, and draw several cotton threads and be entangled on the tungsten filament 20, tungsten filament 20 places storage box 21 outer near the lower bottom part places, when bulb 17 is luminous, has electric current to pass through in the tungsten filament 20, edible oil in the cotton thread group is heated, and sends a burst of smog.

The parts of above-mentioned Fig. 2, Fig. 3, Fig. 4 are placed respectively in each hollow casing, then they are linked to be string, just constituted the simulation electronic firecrackers of Fig. 1.

Claims (1)

1. A kind of electronic firecracker with sound, light, cigarette belongs to electronic product, its feature of being fuming part is: a storage box of depositing edible oil is arranged, one section tungsten filament places box outer near the lower bottom part place, the cotton thread group that is soaked with edible oil of drawing in the storage box is wrapped on the tungsten filament, when electric current by tungsten filament, the tungsten filament heating, the edible oil around it is heated, the light blue or green cigarette of emerging is with the smog of this Simulation firecracker explosion time.
