Description

Technical Field

[0001] The present application belongs to the technical field of fireworks setting off, and specifically relates to an ignition box and a fireworks system. Background Art

[0002] As daily life becomes more and more abundant, people usually set off fireworks to celebrate festivals or grand parties. Currently, fireworks usually include two major markets: large-scale, professional-grade fireworks, and small-scale, consumer-grade fireworks.

[0003] Professional-grade fireworks are usually set off through an ignition system. When multiple fireworks need to be set off one by one, delayed ignition control is usually used, specifically each heater controls the setting off of one firework, and the controller sends an ignition signal to one heater each time, and continues to send it for a period of time. After the setting off, an ignition signal is sent to another heater after a period of time. During the setting off process, there may be fireworks that fail to set off successfully, and they need to be set off again. However, during the process of setting off again, for the fireworks that have already been set off, the existing ignition system will still perform the same ignition steps, resulting in low setting off efficiency.

[0004] Consumer-grade fireworks are usually set off one by one using fuses. When the amount of gunpowder in a single box of fireworks is required, the original single box is usually split into multiple boxes to ensure that the amount of gunpowder in a single box meets the requirements. The multiple boxes of fireworks that have been split are connected by wires containing gunpowder to achieve sequential setting off, but this method still uses fuses to ignite the fireworks, which is somewhat dangerous. Utility Model Content

[0005] The technical problem to be solved by the present application is that the existing ignition system will perform an ignition step on fireworks that have been ignited, resulting in low ignition efficiency, and an ignition box and a fireworks system with high ignition efficiency are provided.

[0006] The technical solution proposed in this application is:

[0007] An ignition box, comprising:

[0008] Multiple heaters;

[0009] A controller, comprising an ignition output terminal and a signal acquisition terminal, wherein the ignition output terminal is used to output an ignition signal;

[0010] A connecting component, one end of which is electrically connected to the ignition output end, and the other end of which is electrically connected to the plurality of heaters;

[0011] A signal generator, one end of which is electrically connected to the connection component, and the other end of which is electrically connected to the signal collection end;

[0012] Wherein, the heater includes an unfired state and an ignited state, and the ignition signal can switch the heater from the unfired state to the ignited state;

[0013] When the heater is in the unignited state, the connecting component can generate an ignition current under the action of the ignition signal, the signal generator can generate a firing signal under the action of the ignition current, and the signal acquisition end can obtain the firing signal; when the heater is in the ignited state, the heater is blown.

[0014] Furthermore, the connection assembly includes a plurality of connection wires, one end of each of the connection wires is electrically connected to the ignition output end, and the other end is electrically connected to the corresponding heater.

[0015] Furthermore, the ignition box includes a plurality of the signal generators, one end of each of the signal generators is electrically connected to the corresponding connecting wire, and the other end is electrically connected to the signal collection end.

[0016] Furthermore, the ignition box also includes an ignition interface and a cable, the connection assembly is electrically connected to the ignition interface, one end of the cable is connected to the ignition interface, and the other end is electrically connected to the plurality of heaters.

[0017] Furthermore, the ignition box also includes a shell, the controller, the connecting component and the signal generator are arranged inside the shell, and the ignition interface is arranged on the side of the shell.

[0018] Furthermore, the ignition box also includes a power supply interface, which is arranged on a side surface of the shell and is electrically connected to the controller, and the power supply interface is used to be electrically connected to an external power source.

[0019] Furthermore, the ignition box also includes a battery compartment, which is arranged in the shell and electrically connected to the controller.

[0020] Furthermore, the ignition box also includes a programming interface, which is disposed on a side surface of the shell and is electrically connected to the controller.

[0021] Furthermore, the ignition box also includes an ignition button, which is arranged on a side surface of the shell and is electrically connected to the controller.

[0022] Furthermore, the ignition box also includes an indicator light, which is arranged on a side surface of the shell and is electrically connected to the controller.

[0023] A fireworks system comprises a packaging box, a plurality of fireworks and the above-mentioned ignition box, wherein the plurality of fireworks are arranged in the packaging box, and each of the heaters is arranged on a corresponding one of the fireworks.

[0024] By using the above-mentioned ignition box, the controller can output ignition signals to multiple heaters one by one through the ignition output terminal, so as to realize the ignition of fireworks one by one. When the fireworks have been ignited, the heater enters the ignition state, and the ignition output terminal sends out an ignition signal. Since the heater is fused, the connection component will not form an ignition current, and the corresponding signal generator will not generate a firing signal. The signal acquisition terminal does not collect the firing signal. The controller determines that the firework has been ignited, and thus skips the firework and transmits the ignition signal to the next firework. There is no need to perform the ignition step for the already ignited fireworks, thereby improving the firing efficiency.

[0025] In addition, the ignition box can also be used in consumer-grade fireworks scenarios, connecting multiple heaters with multiple, for example, 2-12 fireworks, so that multiple fireworks can be ignited in sequence, and the heater action can be remotely controlled by a controller, which is safer.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0035] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0036] On the one hand, if Figure 1 and Figure 4 As shown, an embodiment of the present application provides an ignition box 100 , including a controller 110 , a connecting component 121 , a signal generator 122 and a plurality of heaters 130 .

[0037] The controller 110 includes an ignition output terminal 111 and a signal collection terminal 112. One end of the connection component 121 is electrically connected to the ignition output terminal 111, and the other end is electrically connected to a plurality of heaters 130. One end of the signal generator 122 is electrically connected to the connection component 121, and the other end is electrically connected to the signal collection terminal 112. Each heater 130 is disposed on a corresponding firework 200 and is used to ignite the firework 200.

[0038] The heater 130 includes an unignited state and an ignited state, and the ignition signal output by the ignition output terminal 111 can switch the heater 130 from the unignited state to the ignited state;

[0039] When the heater 130 is in an unignited state, the connecting component 121 can generate an ignition current under the action of the ignition signal, the signal generator 122 can generate a firing signal under the action of the ignition current, and the signal acquisition terminal 112 can obtain the firing signal so that the controller 110 controls the output of the ignition signal according to the firing signal; when the heater 130 is in an ignited state, the heater 130 is blown.

[0040] It should be noted that, in this embodiment, one end of the heater 130 away from the connecting assembly 121 is also connected to the ignition output terminal 111, that is, both the positive and negative electrodes of the heater 130 are connected to the ignition output terminal 111 to form a loop. Figure 1 It is only a circuit diagram, and does not limit the grounding of the heater 130. Specifically, the ignition output terminal 111 has a socket similar to a socket, and the connection component 121 is connected to the ignition output terminal 111.

[0041] In this way, when the heater 130 is in an unignited state, the connecting component 121 forms a loop through the heater 130, so the ignition signal can form an ignition current on the connecting component 121; when the heater 130 is in an ignited state, the heater 130 is blown and the loop is disconnected, so the connecting component 121 does not generate an ignition current.

[0042] By using the above-mentioned ignition box, the controller 110 can output ignition signals to multiple heaters 130 one by one through the ignition output terminal 111, so as to realize the ignition of fireworks 200 one by one. When a firework 200 has been ignited, the heater 130 enters the ignition state, and the ignition output terminal 111 sends an ignition signal. Since the heater 130 is fused, the connection component 121 will not form an ignition current, and the corresponding signal generator 122 will not generate a firing signal. The signal collection terminal 112 does not collect the firing signal. The controller 110 determines that the firework 200 has been ignited, and thus skips the firework 200 and transmits the ignition signal to the next firework 200. There is no need to perform the ignition step for the already ignited firework 200, thereby improving the firing efficiency.

[0043] In addition, the ignition box can also be applied to consumer-grade fireworks setting off scenes, connecting multiple heaters 130 with multiple, for example, 2-12 fireworks 200, so that multiple fireworks 200 are set off in sequence, and the operation of the heaters 130 can be remotely controlled by the controller 110, which is safer.

[0044] What needs to be explained in detail is that, taking the example that the time interval between two adjacent fireworks 200 is 1s, and each firework 200 needs to continuously send an ignition signal for 2s to be fired. When a firework 200 has been fired, if the ignition step is executed for the firework 200, it is necessary to continuously send an ignition signal to the firework 200 for 2s, and then send an ignition signal to the next firework 200 after an interval of 1s; however, in the present application, the heater 130 is fused after entering the ignition state, and the signal generator 122 will not generate a firing signal. After the controller 110 cannot obtain the signal, it can determine that the firework 200 has been fired, and thus directly send an ignition signal to the next firework 200, and will not continue to execute the ignition step for the firework 200, thereby saving the ignition time and interval time, and improving the firing efficiency.

[0045] Furthermore, the ignition box also includes a power driver, which is arranged on the connection component 121 and is used to power drive the ignition signal, and then send the power-driven ignition signal to the heater 130. Optionally, the signal generator 122 is a resistor, and the ignition current on the connection component 121 can flow through the signal generator 122, and a voltage signal will be generated at the signal generator 122, that is, the above-mentioned firing signal.

[0046] like Figure 3 As shown, in one embodiment, the connection assembly 121 includes a plurality of connection wires 1211, one end of each connection wire 1211 is electrically connected to the ignition output terminal 111, and the other end is electrically connected to the ignition interface 141, so as to achieve electrical connection with the corresponding heater 130. Furthermore, the ignition box includes a plurality of signal generators 122, one end of each signal generator 122 is electrically connected to the corresponding connection wire 1211, and the other end is electrically connected to the signal acquisition terminal 112, so as to facilitate the determination of the state of the corresponding heater 130.

[0047] Of course, in other embodiments, a signal generator 122 may have multiple access ports, and each access port is electrically connected to a corresponding connection line 1211 to reduce equipment costs.

[0048] like Figure 2 , Figure 4 and Figure 5 As shown, in one embodiment, the ignition box further includes an ignition interface 141 and a flat cable 142, the connection component 121 is electrically connected to the ignition interface 141, one end of the flat cable 142 is connected to the ignition interface 141, and the other end is electrically connected to the plurality of heaters 130. Further, the ignition box further includes a housing 150, the controller 110, the connection component 121 and the signal generator 122 are all disposed inside the housing 150, and the ignition interface 141 is disposed on the side of the housing 150. Specifically, Figure 5In the embodiment shown, the ignition interface 141 is a 24-core interface, and the flat cable 142 is a 24-core flat cable, which includes 12 wires to electrically connect with 12 heaters 130. Optionally, the heater 130 is a tungsten wire or a thermistor, and the heater 130 is in close contact with the firework 200 lead.

[0049] In one embodiment, the ignition box also includes a programming interface, which is disposed on a side surface of the shell 150 and is electrically connected to the controller 110 so that the firing program of the fireworks 200 can be written into the controller 110 through the programming interface, and then the fireworks 200 can be fired according to the firing program through the controller 110.

[0050] Preferably, at least part of the ignition interface 141 is a programming interface.

[0051] In one embodiment, the ignition box further includes an ignition button 143, which is disposed on the housing 150 and electrically connected to the controller 110, so that the ignition box can be started by controlling the ignition button 143. Figure 2 In the illustrated embodiment, the ignition button 143 is disposed on the front side of the housing 150 .

[0052] In one embodiment, the ignition box further includes an indicator light 144, which is disposed on a side surface of the housing 150 and is electrically connected to the controller 110 to display the operating status of the ignition box. Figure 2 In the illustrated embodiment, the ignition key 143 and the indicator light 144 are located on the same side surface.

[0053] In one embodiment, the ignition box further includes a display screen, which is located on the same side surface of the housing 150 as the ignition button 143 and the indicator light 144 . The display screen is also electrically connected to the controller 110 to display the specific firing status of the multiple fireworks 200 .

[0054] In one embodiment, the ignition box further includes a power supply interface 145, which is disposed on a side surface of the housing 150 and is electrically connected to the controller 110. The power supply interface 145 is used to electrically connect to an external power source, thereby providing power to the controller 110 and other devices. Figure 2 In the illustrated embodiment, the power supply interface 145 is a Type-C interface and is located on the top surface of the housing 150 .

[0055] It needs to be further explained that if Figure 5 As shown, the above-mentioned firing program can also be written into the controller 110 through the power supply interface 145. Figure 4 As shown, by writing a firing program, independent ignition delays are set for multiple fireworks 200, thereby realizing the firing of special effect fireworks 200 products.

[0056] In another embodiment, the ignition box further includes a battery compartment, which is disposed in the housing 150 and is electrically connected to the controller 110. Batteries can be placed in the battery compartment, so that power is supplied by the batteries.

[0057] It should be noted that the power supply interface 145 and the battery compartment can be used alone or together. Among them, using the power supply interface 145 alone can reduce the volume of the housing 150; using the battery compartment alone can facilitate the use of the ignition box. In addition, it can be understood that the above interfaces do not protrude from the housing 150.

[0058] In summary, the ignition box provided by the present application has at least the following advantages:

[0059] 1. It can realize the automatic ignition of multiple fireworks 200, without the need for manual ignition one by one, which is safer and more convenient;

[0060] 2. It is possible to detect whether the fireworks 200 have been set off, and to skip the ignition step for the fireworks 200 that have been set off, thereby shortening the overall setting off time and improving the setting off efficiency.

[0061] On the other hand, Figure 4 As shown, the present application also provides a firework 200 system, including a plurality of fireworks 200 and the above-mentioned ignition box 100, each heater is disposed on a corresponding firework 200, so that the plurality of fireworks 200 can be ignited in sequence.

[0062] Furthermore, the fireworks 200 system also includes a packaging box, and multiple fireworks 200 are arranged in the packaging box to facilitate overall storage and transportation. It should be explained that during the firing process, multiple fireworks 200 can be taken out of the packaging box, and then placed as required, and finally the firing of multiple fireworks 200 is controlled by the ignition box 100.

[0063] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
