Multiple fireworks can be continuously launched by adding an ignition heater power distribution circuit between 3) and the ignition switch.
The power distribution circuit is a circuit that performs stepping by a signal input and sequentially supplies power to each ignition heater. Although the metal plate (19) for mounting the heater assembly here is attached to the spiral metal plate, it is shaped so that it can fit inside the outer cylinder (3) and the bamboo higo (15) can freely pass through the flying fireworks. Anything that has a hole in it may be used. In addition, the use of a metal plate is non-flammable, and in the power distribution circuit to the ignition heater (2), there is an advantage that one of the wiring cords can be omitted by flowing one of the electrodes to the metal plate for common use.

The embodiment of FIG. 5 is a block diagram of an electric circuit for launching a plurality of flying fireworks continuously or in combination with a timer circuit at intervals. The shape shown in FIG. 4 is housed in a cylindrical casing, and the heater receiver (2
The power is supplied to 3). If the shape of this housing is finished like a square or a real rocket launch pad, children's enjoyment will be doubled. Basically, an ignition heater power distribution circuit (106) for distributing power to each ignition heater assembly (22), a power relay (101) and an ignition (2)
8) Power unit of battery, power relay timer circuit (102) for controlling it, control circuit such as power relay control circuit (103), and wireless and infrared receiving circuit (108) for sending drive signal to the control circuit Launch time setting timer The circuit (109) includes an audio catch sensor (202), a far-infrared catch sensor (203), an ultrasonic catch sensor (204), and an auxiliary circuit of a sensor control circuit.

As an electric movement in the embodiment of FIG. 5, when the power switch (100) is first turned on, this switch is set to 2
Since the circuit 2 contacts are used, the control circuit power switch (100) is also turned on and the power lamp (27) is turned on. Therefore, when the ignition heater (2) is covered with flying fireworks excluding the fuse, the actuator of the micro switch (24) passing between the heater electrodes is pushed down by the load of the fireworks and becomes an energized state, but another safety circuit works. The power relay (101) is still OF
It is F. Set the safety switch (29) to the ignition heater (2).
When switched to the side, the safety switch actuation indicator lamp (26) goes out and joins with the primary side coil of the power relay (101).
As for the operation of the control circuit, the position changeover switch (105) is connected to the wireless and infrared receiving circuits in the figure. When an ignition signal is sent from the infrared transmitter, the output signal is received by the wireless and infrared reception circuit (108), passes through the position changeover switch (105), is amplified by the power relay control circuit (103), and the ignition heater power distribution circuit ( 106) is driven to sequentially switch contacts to the heater assembly receiver (23). On the other hand, the timer circuit (10
When the power relay (101) is operated via 2) and the ignition heater (2) is supplied with electricity for 5 seconds from the ignition battery (28) to cause red heat, ignition occurs in the flying pyrotechnic powder cylinder and gas due to intense self-combustion is generated. The high-pitched tone "Hu" is left behind, reaching about 30 m above the sky, and a series of movements ends with "Burn" and a loud popping sound. When the functions of the infrared transmitter / receiver and the timer circuit (102) are supplemented here, the infrared controller is the same as that used in household TVs, video devices, etc.
If it is about 0 m and has multiple functions, the power switch, safety switch, etc. can all be integrated in the controller. In the timer circuit (102), the ignition heater (2) is for preventing overheating and melting, and the heater assembly (22).
When many are arranged, it can be used as a substitute for the microswitch function in terms of mounting space cost.

The sensor circuit will be described with reference to FIG. The sound, smoke, movement, smell, and plosive sound after the ignition of flying fireworks are very effective for threatening birds and beasts. Therefore, as a use for the other side, it was diverted to a bird and beast damage prevention machine. The point is how quickly you can catch the birds and beasts and issue a warning with fireworks. Therefore, it became a circuit that puts emphasis on the sensor part. The crow, who has the highest learning ability among birds, eats chicken food, attacks eggs, chicks, or piglets as a group, does bad work on all agricultural products such as peaches, grapes, watermelons, persimmons, and the damage amount is It is a considerable amount of money. Therefore, using the place with high learning ability in reverse, paying attention to the point that once you give a strong fear, you can not approach, for example, when you come to eat an apple in an orchard, a fireworks ignition device is camouflaged under the tree and a crow If you confirm that you are flying back again and send a signal with a wireless transmitter to launch a flying fireworks from under a tree where a crow has stopped, a very high bird-following effect will rise. Like monkeys, monkeys are wise men and formidable opponents. With the above method, the same effect can be obtained by changing the fireworks into fireworks.

The launch time setting timer circuit (109) will be described with reference to FIG. Since this circuit has a programming function, you can expect a bird-following effect in a program that suits the installation location, such as launching at intervals or launching concentratedly in a short time.

FIG. 5 shows an embodiment of the voice catch sensor (202), the far-infrared catch sensor (202) and the ultrasonic catch sensor connected to the sensor control circuit (201). Voice catch sensor (2
02) is a circuit that outputs a signal to ignite fireworks in response to the voice of birds and beasts. This is a single bird or a bird who is a watchman stopping on a tree and calling a friend, collecting and amplifying with a microphone and driving a power relay (101) and an ignition heater (2).
Is a circuit that ignites red heat. This circuit is equipped with a microphone sensitivity adjustment function, and the reaction distance can be adjusted as necessary. Also, the amplifier circuit of the microphone is set to stop during the time from when the fireworks are launched to the sound of explosion when the voice reacts to the voice. This is because without this circuit, when the first fireworks are launched, they all respond to the sound of popping and launch. As another method, a circuit that does not operate without two voices in a short time may be incorporated. Next, the far-infrared catch sensor (203) catches the weak far-infrared rays emitted by people and animals, and is currently used as an automatic door at the entrance or an intrusion catch sensor for crime prevention. Then, it is used to protect nocturnal foxes, raccoons, cabbage, humans, etc. from crop damage. This sensor is effective for the birds and beasts that enter without speaking and is mainly used at night. Therefore, the day / night operation changeover switch (104) is used by switching to night. This switch is a cds that responds to light
It is a circuit that uses the, and the range of use is expanded to the operation only at night and the operation only at day at the switching position. The function of the ultrasonic catch sensor (204) is composed of a microphone in the oscillation output speaker receiving section. As for the sound range, sound waves are emitted centering around 40 kilohertz that cannot be heard by the human ear, and the reflected sound is collected by a microphone, and the output changes due to the disturbance of the sound waves to determine the presence or absence of intrusion. This is effective for birds flying from the sky without producing any sound. The power relay (101) is driven by these sensor outputs to launch fireworks, but instead of this, a device that emits a warning sound, such as a speaker, buzzer, strobe, or searchlight, can be used as a crime prevention device. Can be measured.

[0029]

Since the present invention is constructed as described above, the following effects are exhibited. Conventionally, fireworks were ignited with a lighter, match, candle, etc. on the squib, but this device uses an electric ignition method. By using electricity, it is possible to utilize the advanced electronic components of recent years, and it is possible to automatically launch fireworks by remote control that could never be done with conventional combinations of various sensors such as ignition heaters, timers, etc. Accordingly, the fireworks could be protected against moisture by eliminating the fuse of the flying fireworks. Flying Fireworks By igniting the gunpowder directly inside the barrel, children can relax and enjoy the fireworks, which is a summer tradition, regardless of wind and rain. On the other side, the fireworks movement, plosive noise, low price, and the characteristics of gunpowder were used to prevent damage to birds and animals. The sound pressure level of a blast machine using propane gas and carbide is high, and since it is heavy, it is necessary to choose the installation location. In this respect, the device using this fireworks captures the behavior of birds and beasts with various sensors and threatens with fireworks in a timely manner, so the fear is doubled and the effect is very high, and it is also small and lightweight, easy for women and girls. Since it can be moved to and installed in, it was possible to eliminate the decrease in efficacy due to habituation due to fixed-point installation. By using a seasonal product called fireworks only for summer as a preventive device for bird and beast damage, it can be used all year round and an economic effect can be expected.
