Description

The utility model relates to a new structure of firecrackers, in particular to an electronic circuit to generate sequential lighting and reduction actions, and cooperate with the sound output of the firecrackers to imitate the actual effect of the firecrackers being lit and avoid cleaning The design of cannon scraps.

Chinese people never forget to set off strings of firecrackers during Chinese New Year's festivals or festive festivals, adding to the lively atmosphere with the sound of crackling explosions and the scattering of flames. , has become the garbage landscape that everyone is least willing to see. It not only increases the mess in the local environment, but also takes time and effort in cleaning and processing, and the gunpowder explosion generated when the firecrackers are set off is harmful to the surrounding people. Different damages can be avoided, especially when temple celebrations or gods are on tour, there are many believers or people onlookers and crowds, the gunpowder explosion caused by setting off whips is the most dangerous and terrible; in addition, the explosion caused by setting off firecrackers The sound is particularly loud, which makes children (especially babies) or the elderly sleeping soundly at night more likely to be frightened, and the noise pollution is greatly increased for the quiet maintenance of the local environment.

Therefore, in view of the above-mentioned traditional firecrackers when they are set off, the creators started to study and design, and after several tests and improvements, they finally created A new structure of firecrackers that can imitate the actual effect of setting off firecrackers and eliminates the need to clean up firecrackers is developed by electronic circuits to generate sequential lighting and dimming actions, combined with the sound output of firecrackers.

In order to enable people to further understand the technical structural features used by the utility model and achieve the functional purpose, the detailed description is as follows in conjunction with the following drawings:

Fig. 1 is a circuit diagram of the utility model;

Fig. 2 is a combined perspective view of the utility model;

Fig. 3 is the embodiment figure of the utility model.

First of all, please refer to Fig. 1, which is the control circuit (1) of the present invention, which is mainly composed of an integrated circuit IC (12) that can output lighting signals in sequence and correspondingly emit firecracker sounds at the same time. The first pin of the integrated circuit IC (12) is connected in series with a power switch (SW1) to the positive terminal of the battery (11) to control whether the power supply (Vcc) is powered; the second pin and the third pin are externally connected to an oscillation transistor ( XTL), and external bulbs (L1-L15) are connected to the 4th to 10th and 12th to 19th pins in sequence, and the 20th pin is connected to the drive amplifier transistor (Q1) through the adjustable resistor VR1 (13) , to push the speaker (SP) (14) to amplify the sound output.

During combination implementation, please refer to shown in Fig. 2, control circuit (1) of the present utility model is assembled in the top body (21) of firecracker (2), and the power switch (SW1) of its control circuit (1) and adjustable The resistor VR1 (13) protrudes from one side of the main body (21), and the speaker (SP) (14) is positioned in the other side of the main body (21), and is placed vertically under the main body (21). A plurality of transparent cylinders (22), and light bulbs (L1-L15) connected by wires (15) are installed in the cylinders (22) to form a string of firecrackers (2).

To implement the action, please refer to Figure 3, turn the power switch (SW1) to the on position, so that the power supply (Vcc) provided by the positive terminal of the battery (11) will start to generate an oscillation signal output due to the oscillation transistor (XTL), To make the bulbs (L1~L15) turn on and off in sequence, and at the same time output a firecracker sound corresponding to pin 20, which is amplified by the transistor (Q1) to drive the speaker (SP) (14) to sound; that is, when the integrated The oscillating signal output of the circuit IC (12) is used to light the bulb (L1), and its 20th pin simultaneously outputs an explosion sound which is amplified by the transistor (Q1) and drives the speaker (SP) (14) to output sound. After the light bulb (L1) is extinguished, the next light bulb (L2) is lit to emit light, and at the same time, an explosion sound is output through the speaker (SP) (14), and the light bulbs (L1-L15) are turned on successively in this way. At the same time, it emits an explosion sound similar to firecrackers, so that the plurality of transparent cylinders (22) vertically placed under the main body (21) can be sequentially lit up to emit light. , and imitate the explosion effect produced by traditional firecrackers when they are set off; when the light bulbs (L1~L15) are all activated, the integrated circuit IC (12) will automatically output a louder explosion signal to the transistor (Q1) to amplify , to drive the loudspeaker (SP) (14) to send a bigger sound, and as the end situation after setting off the firecrackers (2).

In addition, the control circuit can also be assembled on other toys with light and sound actions.

Combining the above-mentioned implementation actions, the utility model can achieve the following many improved effects:

1. With the light bulbs installed in the transparent cylinder, the actions of lighting and extinguishing are performed one by one in order, and an explosion sound is output from the horn at the same time during the lighting time of the bulbs to match, so as to imitate the firecrackers when they are set off. The same effect; at the same time, after all the bulbs are lit and extinguished, there will be a louder explosion sound output as the end of the firecrackers, so that there will be no traditional firecrackers. Fly to the ground and cause environmental mess and pollution.

2. It can eliminate the danger of injury to the crowd or believers caused by the explosive explosion of traditional firecrackers when they are set off. At the same time, if the firecrackers are used at night, the explosion volume can also be adjusted by adjusting the resistor VR1 (13). Its output volume is moderate and will not cause fright to neighboring houses, so as to prevent and control environmental noise.

3. It can be used repeatedly to achieve the practical virtue of increasing income and saving people's livelihood, and can guide the society to reduce the bad trend of waste and extravagance.
