Abstract

The utility model relates to a firecracker structure, mainly comprising a control circuit and a firecracker body. The control circuit is assembled and loaded in the top end body of the firecracker, one side end of the body is protruded with a power switch, and the other side end of the body is positioned and arranged a loudspeaker. A plurality of transparent barrel bodies are arranged under the body in series, bulbs which are connected into a communicated loop through a connecting wire are arranged in the barrel bodies, and the firecracker is formed by the combination of the elements. When the bulbs are light, the loudspeaker sends out the explosive sound of the firecracker simultaneously, after all the bulbs finishing the movement, a relatively great explosive sound is sent out to indicate the end of firing the firecracker, and thereby, emulating the equal effect of firing the firecracker is reached, and gun dust sweeping is avoided.

Description

Firecracker structure

The utility model is about a kind of firecrackers new structure, refers to especially a kind ofly produce by electronic circuit that in regular turn light is bright to subtract action, and cooperates the firecrackers voice output, reaching the actual effect that can imitate out firecrackers to be put by point, and exempts the design of cleaning big gun bits.

In on New Year's Day or other festivals Chinese or celebrating red-letter day, always do not forget to put the string firecrackers, its thunderbolt of mat explosion sound and flame light scattering are waved in the wind increases lively atmosphere, yet, it is the big gun bits pile on full ground that the Spring Festival holidays one cross, become everybody and least be ready the rubbish view seen, it is not only dirty and messy to increasing suddenly on the local environment, on cleaning is handled, also be time-consuming and effort simultaneously, and the gunpowder explosion that is produced during this firecracker setting-off has the injury power that difference is avoided again for people on every side, especially when temple celebration or gods tour of inspection, the believer who surrounds and watches or the common people are much more special and crowded, and whip is seted off by institute, and to put the tool of gunpowder explosion injury power of generation dangerous and fearful; In addition, the blast sound of generation that firecrackers are seted off is again loud especially, makes the child (especially baby) in night sleeps in Shen or the old man is easier gets a fright, and increases noise pollution suddenly for the quiet maintenance on the local environment.

Edge this, the creator in view of the above traditional firecrackers when setting off, the back something lost drawback that is produced in all environmental protection influences, set about grinding and think design, assist a ruler in governing a country, under several times testing and improving with practice manufacturing experience for many years, finally create and a kind ofly produce by electronic circuit that in regular turn light is bright to subtract action, and cooperate the firecrackers voice output, reaching the actual effect that can imitate out the firecrackers point to put, and exempt the firecrackers new structure of cleaning big gun bits.

By the technical pattern feature that makes people can further understand the utility model to be used, reach functional purpose, now in conjunction with the following drawings detailed description as the back:

Fig. 1 is the line map of the utility model;

Fig. 2 is the combination stereo appearance figure of the utility model;

Fig. 3 is the enforcement illustration of the utility model.

At first, see also shown in Figure 1, this is the control circuit (1) of the utility model, it be by one can export in regular turn light signal and simultaneously the correspondence IC (12) that sends firecrackers sound be main member, this IC (12) the 1st pin for serial connection one power switch (SW1) to the anode of battery (11), whether with the power supply of control power supply (Vcc); The external oscillistor of the 2nd pin and the 3rd pin (XTL), and be circumscribed with bulb (L1～L15) in regular turn in the 4th pin～the 10th pin and the 12nd pin～the 19th pin, and the 20th pin is through adjustable resistance VR1(13) connect driving amplifier transistor (Q1), to promote the output of loudspeaker (SP) (14) voice emplifying.

When combination is implemented, see also shown in Figure 2, the control circuit (1) of the utility model is assembled in the top main body (21) of firecrackers (2), the power switch (SW1) and the adjustable resistor VR1(13 of its control circuit (1)) be based in one of main body (21) side, reach loudspeaker (SP) (14) location is set in another side of main body (21), and hang down in main body (21) below and to be provided with a plurality of transparent cylindrical shells (22), and in cylindrical shell (22) in, install bulb through lead (15) binding (L1～L15) for becoming a string firecrackers (2).

Implement start, see also shown in Figure 3, power switch (SW1) is pulled position to conducting, make battery (11) power supply (Vcc) that anode provided begin to produce oscillator signal output because of oscillistor (XTL), to make bulb (L1～L15) light in regular turn, extinguish action, and correspondence is exported a firecrackers sound at the 20th pin simultaneously, amplifies and driving loudspeaker (SP) (14) sounding through transistor (Q1); That is the oscillator signal of working as IC (12) is exported, to make bulb (L1) when lighting, its the 20th pin is promptly exported an explosive sound simultaneously and is amplified through transistor (Q1), export sounding and drive loudspeaker (SP) (14), after bulb (L1) extinguishes, next bulb (L2) is lighted luminous immediately, and export an explosive sound again through loudspeaker (SP) (14) sounding simultaneously, so one by one light bulb (L1～L15) start in regular turn, and the explosive sound when sending a similar firecracker setting-off simultaneously cooperates, make the plural transparent cylindrical shell (22) that hangs down and establish in main body (21) below, can be one by one (it is luminous that L1～L15) is lighted, and the explosive effect of imitating out traditional firecrackers to be produced when setting off because of bulb in regular turn; (L1～L15) is after all starts finish when bulb, IC (12) can amplify for electric transistor (Q1) from line output one more loud detonator signal, send bigger sound to drive loudspeaker (SP) (14), and seted off the situation that finishes of back as firecrackers (2).

In addition, described control circuit also can be assembled on the toy of the luminous sound start of other tools.

Comprehensive above-mentioned enforcement start, the utility model can reach following many improvement effects:

1. by the bulb of being installed in the transparent cylindrical shell, the order action of lighting, extinguishing one by one, and in bulb is lighted the time, export an explosive sound cooperating at loudspeaker simultaneously, thus imitate out plan like the equal effect of firecrackers when setting off; Simultaneously, after all lighting at bulb, extinguishing start, also have a more loud blast voice output, with as the end situation behind the firecracker setting-off, so just do not have traditional firecrackers after setting off, its big gun bits completely fly and cause environment dirty and messy and pollute.

2. can eliminate traditional firecrackers when setting off, its gunpowder explosion cause is dangerous for spectator or believer's injury, simultaneously, if firecrackers are when using night, also can be by adjustable resistance VR1(13) adjustment blast volume, make its output volume moderate and can not cause scaring, reach the control of environmental protection noise contiguous household.

3. can repeat repeatedly to use, reach the people's livelihood actual effect virtue of saving of increasing income, and can follow the bad common practice of kind guiding society with the luxury that cuts the waste.
