Description

Technical Field

[0001] The utility model relates to the technical field of ignition devices, in particular to a fuse ignition device. Background Art

[0002] A fuse ignition device is a device designed to ignite a fuse remotely. It usually consists of an igniter and a remote control.

[0003] When the user needs to ignite the fuse, they place it on the lighter, bringing it into contact with the heating wire. They then turn on the main switch on the lighter, placing the wireless receiver in standby mode. Next, they press the remote control switch, and the wireless transmitter sends a wireless signal to the wireless receiver on the lighter. Upon receiving the signal, the wireless receiver controls the main control circuit board, transmitting power to the heating wire, generating heat and igniting the fuse.

[0004] When lighting firecrackers, users usually light the fuse first and then throw it away. After pressing the remote control, the user needs to throw the lighter away.

DETAILED DESCRIPTION

[0047] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is described as "connected" to another element, it can be directly on the other element, or there can be one or more centered elements therebetween. The terms "upper", "lower", "left", "right", "upper end", "lower end", "top" and "bottom" used in this specification indicate an orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0048] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art in the field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0049] The following combination Figures 1 to 6 , the lead ignition device 100 provided in the embodiment of the present application is described in detail through specific examples.

[0050] Please also refer to Figure 1 、 Figure 2 and Figure 3 , Figure 1 This is a schematic structural diagram of the fuse ignition device provided by the present utility model; Figure 2 This is a structural diagram of the igniter of the fuse ignition device provided by the utility model; Figure 3 This is a diagram of the usage state of the igniter of the fuse ignition device provided by the present invention. The fuse ignition device 100 provided in one embodiment of the present invention includes a shell 10, an igniter 20 and a remote control 30. A first accommodating chamber 11 is provided in the shell 10; the igniter 20 is used to clamp the fuse and ignite the fuse, and part of the igniter 20 is accommodated in the first accommodating chamber 11; the remote control 30 is used to remotely control the igniter 20 to ignite the fuse; wherein, the igniter 20 includes an ignition part 21 and a clamping part 22, the ignition part 21 is accommodated in the first accommodating chamber 11, the clamping part 22 is slidably connected to the shell 10, the position of the ignition part 21 corresponds to the position of the clamping part 22, and the clamping part 22 can slide on the shell 10 to gradually move away from or approach the ignition part 21, thereby forming an accommodating space 23 for accommodating the lead or abutting each other to clamp the lead.

[0051] In this embodiment, a first accommodating cavity 11 is provided in the shell 10, and the ignition part 21 is accommodated in the first accommodating cavity 11, and then the outer shell cover can be placed on the first accommodating cavity 11, so as to cover the ignition part 21 and prevent the components in the ignition part 21 (such as circuit boards, power supplies, etc.) from being exposed to the air, thereby preventing the components in the ignition part 21 from being damaged.

[0052] Among them, the clamping part 22 is slidably connected to the shell 10, and the position of the ignition part 21 corresponds to the position of the clamping part 22. When the clamping part 22 slides on the shell 10 to gradually move away from the ignition part 21, a storage space 23 can be formed between the clamping part 22 and the ignition part 21. At this time, the fuse can enter the storage space 23 and fit with the ignition part 21, which facilitates the subsequent ignition part 21 to ignite the fuse; then the clamping part 22 can slide in the opposite direction on the shell 10 to gradually approach the ignition part 21. At this time, the clamping part 22 can fit with the outer surface of the shell 10 to clamp the lead and then fix the lead. Through such a setting, the clamping part 22 can be controlled to slide on the shell 10 so that the lead can contact the ignition part 21 and after contact, the clamping part 22 and the outer surface of the shell 10 can jointly fix the lead. This can prevent the lead from separating from the ignition part 21 during the ignition process.

[0053] Regarding the aforementioned remote control 30, it is used to remotely control the igniter 20 to ignite the fuse. When the user presses a button on the remote control 30, the microprocessor inside the remote control 30 receives the command and converts it into a corresponding digital signal. This digital signal is then encoded by an encoder into an analog signal for transmission. If it is a radio wave remote control 30, the encoded analog signal is converted into radio waves and transmitted via an antenna; if it is an infrared remote control 30, the analog signal is converted into an infrared signal and transmitted via an infrared diode. The ignition section 21 of the igniter 20 is equipped with a receiver to receive the signal transmitted by the remote control 30. After receiving the signal, the receiver decodes it and converts it back into the original digital signal. This decoded digital signal is then transmitted to the control circuit of the igniter 20 for processing. Based on the decoded command signal, the control circuit determines the user's intended action, such as igniting the fuse. If the command is to ignite the fuse, the control circuit sends the corresponding control signal to the ignition section 21 of the igniter 20. Upon receiving the control signal, the ignition section 21 generates sparks or high temperatures, thereby igniting the fuse.

[0054] In some other embodiments, when the remote control 30 and the igniter 20 need to be re-paired during the first use, they enter the pairing mode. In the pairing mode, the remote control 30 will send a signal containing its identity (such as ID) and random number and other information. After receiving this signal, the igniter 20 will record it and compare it with its own internal information to confirm whether it matches. When the remote control 30 sends a signal again, the igniter 20 can quickly identify and respond. If an unauthorized remote control 30 controls the igniter 20, the igniter 20 will not respond. Through such a setting, the pairing function can reduce the possibility of misoperation. Only the remote control 30 that is successfully paired with the igniter 20 can send a valid control signal, so even if there are other similar remote controls 30 nearby, they will not interfere with the igniter 20.

[0055] Please join us Figure 4 and Figure 5 , Figure 4 This is a cross-sectional view of the igniter of the fuse ignition device provided by the present invention; Figure 5 This is a schematic diagram of an explosion of the igniter of the fuse ignition device provided by the present invention. In some embodiments, the housing 10 includes a first abutment plate 12 disposed on the outer periphery of the ignition portion 21. The clamping portion 22 includes a second abutment plate 221, which is positioned correspondingly to the first abutment plate 12 and can gradually move away from or closer to the first abutment plate 12.

[0056] The housing 10 includes a first abutting plate 12 , which is disposed on the outer periphery of the ignition portion 21 . The clamping portion 22 includes a second abutting plate 221 , which is disposed correspondingly to the first abutting plate 12 . When it is necessary to prevent the lead from being on the ignition part 21, the clamping part 22 slides on the shell 10 to gradually move away from the ignition part 21, and the second abutment plate 221 of the clamping part 22 and the first abutment plate 12 of the shell 10 are separated from each other, so that an accommodating space 23 is formed between the clamping part 22 and the ignition part 21. At this time, the lead can enter the accommodating space 23 and fit with the ignition part 21, so as to facilitate the subsequent ignition part 21 to ignite the lead; but when it is necessary to clamp and fix the lead, the clamping part 22 can slide in the opposite direction on the shell 10 to gradually approach the ignition part 21. At this time, the second abutment plate 221 of the clamping part 22 can fit with the first abutment plate 12 of the shell 10 to clamp the lead, thereby fixing the lead. Through such a setting, the clamping part 22 can be controlled to slide on the shell 10, so that the second abutment plate 221 can gradually move away from or approach the first abutment plate 12, thereby making the lead fit with the ignition part 21 and then fixing the lead to prevent the lead from separating from the ignition part 21 during the ignition process.

[0057] In some more specific examples, the first abutment plate 12 is located on the outer periphery of the ignition portion 21. The first abutment plate 12 can provide a certain degree of protection to the ignition portion 21. The first abutment plate 12 encloses and protects the ignition portion 21. When the second abutment plate 221 gradually approaches the ignition portion 21, it will abut against the first abutment plate 12 when it reaches a specific position, thereby fixing the lead wire; this also restricts the second abutment plate 221 from further movement toward the ignition portion 21, thereby preventing the second abutment plate 221 from damaging the ignition portion 21.

[0058] In some embodiments, the shell 10 is further provided with a second accommodating chamber 13, which is arranged on the back of the ignition part 21; the clamping part 22 also includes a sliding plate 222 and a connecting plate 223, the sliding plate 222 is arranged on both sides of the connecting plate 223, and the two ends of the sliding plate 222 are respectively connected to the connecting plate 223 and the second abutment plate 221; the connecting plate 223 is covered on the opening of the second accommodating chamber 13, and the sliding plate 222 is slidably connected to the second accommodating chamber 13.

[0059] A second accommodating cavity 13 is defined in the housing 10 . The second accommodating cavity 13 can be used for movement of the clamping portion 22 . When the clamping portion 22 slides on the housing 10 , it moves in the second accommodating cavity 13 .

[0060] The clamping portion 22 further includes a sliding plate 222 and a connecting plate 223, which can be connected to the second abutting plate 221 via the sliding plate 222. The connecting plate 223 is disposed on the opening of the second accommodating cavity 13, and the sliding plate 222 is slidably connected to the second accommodating cavity 13.

[0061] When it is necessary to move the clamping portion 22 away from the ignition portion 21, a force can be applied to the connecting plate 223. At this time, the connecting plate 223 on the opening of the second accommodating cavity 13 can move toward the accommodating cavity, and the connecting plate 223 can drive the sliding plate 222 to move together. At this time, the sliding plate 222 can slide on the shell 10, so that the sliding plate 222 drives the second abutment plate 221 away from the ignition portion 21. At this time, an accommodating space 23 is formed between the second abutment plate 221 and the first abutment plate 12 for the lead to enter and fit with the ignition portion 21. Then, when the lead needs to be fixed, a force in the opposite direction can be applied to the connecting plate 223 (the force in the opposite direction can be applied by the user or a compression spring can be provided). At this time, the connecting plate 223 located in the second accommodating chamber 13 can move toward the opening of the accommodating chamber, and the connecting plate 223 can drive the sliding plate 222 to move together. At this time, the sliding plate 222 can slide on the shell 10, so that the sliding plate 222 drives the second abutment plate 221 to gradually approach the ignition part 21. At this time, the second abutment plate 221 and the first abutment plate 12 abut against each other to fix the lead, so that the lead can always be in contact with the ignition part 21.

[0062] In some embodiments, sliding grooves 131 are opened on both sides of the housing 10 , and the sliding grooves 131 are communicated with the second accommodating cavity 13 ; the sliding plate 222 is slidably connected to the sliding grooves 131 .

[0063] In this embodiment, the housing 10 is provided with a slide groove 131 on both sides, and the sliding plate 222 is disposed in the slide groove 131. When a force is applied to the connecting plate 223, the connecting plate 223 moves in the second accommodating cavity 13, and the sliding plate 222 can slide in the slide groove 131. This arrangement enables the movement of the sliding plate 222 and the connecting plate 223, and the slide groove 131 can guide the sliding of the sliding plate 222, preventing the entire movement of the clamping portion 22 from being offset.

[0064] In some embodiments, the clamping portion 22 further includes a return spring 224 , one end of the return spring 224 abuts against the connecting plate 223 , and the other end abuts against the inner wall 132 of the second accommodating cavity 13 .

[0065] The two ends of the return spring 224 respectively abut against the connecting plate 223 and the inner wall 132 of the second accommodating chamber 13. When subjected to an external force, the return spring 224 deforms and compresses or expands, accumulating potential energy. When the external force disappears, the return spring 224 releases the energy and returns to its initial state.

[0066] In this embodiment, when the lead wire needs to be attached to the ignition portion 21, the connecting plate 223 can be pressed to apply a force. The connecting plate 223 on the opening of the second accommodating cavity 13 can move toward the accommodating cavity, and the connecting plate 223 drives the sliding plate 222 to move together. At this time, the sliding plate 222 can slide on the housing 10, thereby driving the second abutting plate 221 away from the ignition portion 21. At this time, a accommodating space 23 is formed between the second abutting plate 221 and the first abutting plate 12 for the lead wire to enter and attach to the ignition portion 21. At this time, the connecting plate 223 gradually approaches the return spring 224 in the second accommodating cavity 13, and the return spring 224 is compressed to accumulate potential energy. Then, when the connecting plate 223 is no longer pressed, the force disappears, and the return spring 224 can expand due to its accumulated potential energy, thereby returning to its initial state. At this time, the end of the return spring 224 drives the connecting plate 223 located in the second accommodating cavity 13 to move toward the opening of the accommodating cavity, and the connecting plate 223 can drive the sliding plate 222 to move together. At this time, the sliding plate 222 can slide on the shell 10, so that the sliding plate 222 drives the second abutment plate 221 to gradually approach the ignition part 21. At this time, the second abutment plate 221 and the first abutment plate 12 abut against each other to fix the lead, so that the lead can always be in contact with the ignition part 21.

[0067] In some embodiments, a fixing protrusion 2231 is provided on the connecting plate 223, and a surrounding bone 1321 is provided on the inner wall 132 of the second accommodating cavity 13, and the positions of the surrounding bone 1321 and the fixing protrusion 2231 correspond to each other; one end of the return spring 224 is connected to the fixing protrusion 2231, and the other end is provided in the surrounding bone 1321.

[0068] By providing a fixing protrusion 2231 on the connecting plate 223, one end of the return spring 224 is clamped onto the fixing protrusion 2231, thereby securing one end of the return spring 224. A rib 1321 is then provided on the inner wall 132 of the second accommodating cavity 13, and the other end of the return spring 224 is received within the rib 1321, thereby securing the other end of the return spring 224. This arrangement secures the return spring 224 and prevents it from falling or falling off.

[0069] Furthermore, the position of the peripheral bone 1321 and the position of the fixing protrusion 2231 are set correspondingly, so that the two ends of the return spring 224 are located on the same horizontal line, and the return spring 224 can be set horizontally to prevent the return spring 224 from bending.

[0070] In some embodiments, the second abutment plate 221 is provided with an opening 2211, the position of the opening 2211 corresponds to the position of the ignition portion 21; an abutment protrusion 2212 is provided on the outer peripheral side of the opening 2211, the abutment protrusion 2212 is arranged toward the ignition portion 21 and abuts against the first abutment plate 12.

[0071] When the second abutting plate 221 and the housing 10 abut against each other, the ignition portion 21 is communicated with the outside through the opening 2211. By providing the opening 2211 on the second abutting plate 221, the second abutting plate 221, the ignition portion 21 and the housing 10 can be prevented from forming a closed space.

[0072] Furthermore, an abutment protrusion 2212 is provided on the outer periphery of the opening 2211. This abutment protrusion 2212 is used to abut against the first abutment plate 12 to secure the lead wire. When the second abutment plate 221 abuts the first abutment plate 12, the abutment protrusion 2212 creates a gap between the second abutment plate 221 and the first abutment plate 12, which can be used to accommodate the lead wire.

[0073] See also Figure 6 , Figure 6 This is a schematic diagram of the ignition unit of the wire ignition device provided by the present invention. In some embodiments, the ignition unit 21 includes a heating wire 211, a main control board 212, and an energy supply member 213. The energy supply member 213 is connected to the heating wire 211 via the main control board 212. The energy supply member 213 and the main control board 212 are disposed within the first accommodating cavity 11, while the heating wire 211 is located on the back side of the second accommodating cavity 13, corresponding to the position of the clamping portion 22.

[0074] The energy supply element 213 is connected to the heating wire 211 via the main control board 212. The energy provided by the energy supply element 213 is regulated and distributed to the heating wire 211 by the main control board 212 to achieve ignition. When ignition is required, the energy supply element 213 provides energy, and the main control board 212 controls the distribution and transfer of energy, ultimately causing the heating wire 211 to reach a sufficiently high temperature to ignite the fuse or object.

[0075] The energy supply component 213 and the main control board 212 are disposed within the first accommodating chamber 11. After the energy supply component 213 and the main control board 212 are housed in the first accommodating chamber 11, a top cover can be placed on the first accommodating chamber 11 to close the first accommodating chamber 11. This protects the energy supply component 213 and the main control board 212 from interference or damage from the external environment and facilitates overall assembly and maintenance.

[0076] The heating wire 211 is located on the back of the second accommodating cavity 13 and corresponds to the position of the clamping portion 22. This arrangement ensures that the heating wire 211 can accurately contact the fuse or object to be ignited, and the clamping portion 22 can stably fix these fuses or objects, making the ignition process more reliable.

[0077] In some embodiments, the ignition unit 21 is further provided with a time delay switch 214, which is connected to the main control board 212. The time delay switch 214 is connected to the main control board 212 and can control the delay time of the ignition operation through the main control board 212, thereby providing a more flexible and safe operation mode.

[0078] See also Figure 7 , Figure 7 This is an exploded view of the first abutment plate and housing of the fuse ignition device provided by the present invention. In some embodiments, the housing 10 defines a third accommodating chamber 14, which is disposed opposite the second accommodating chamber 13. The heating wire 211 is housed within the third accommodating chamber 14, which is in communication with the opening 2211. The first abutment plate 12 covers the third accommodating chamber 14 and is detachably connected to the housing 10.

[0079] Among them, the first abutment plate 12 and the shell 10 are detachably connected, specifically, they can be connected by bolts. After the heating wire 211 is set in the third accommodating chamber 14, the first abutment plate 12 is then fixed above the third accommodating chamber 14 by bolts, so that the heating wire 211 can be fixed. When the heating wire 211 is used more times and the heating wire is damaged (for example, after the lead burns, the chemical components therein oxidize and corrode the heating wire, and the lead ignites and burns the heating wire), the bolts can be twisted to separate the first abutment plate 12 and the shell 10, and then the heating wire 211 can be replaced. Through such a setting, on the one hand, it is convenient to replace the damaged heating wire 211, and on the other hand, the first abutment plate 12 can prevent the flame from extending to the shell 10 after the lead is ignited, causing damage to the shell 10.

[0080] The third accommodating cavity 14 communicates with the opening 2211 on the second abutting plate 221, and the heating wire 211 is housed within the third accommodating cavity 14. When the lead needs to be secured, the second abutting plate 221 abuts against the housing 10. If the heating wire 211 were directly attached to the housing 10, the second abutting plate 221 would easily come into contact with the heating wire 211, potentially damaging it. By providing the second accommodating cavity 13 within the housing 10, the third accommodating cavity 14 protects the heating wire 211, preventing direct contact between the second abutting plate 221 and the heating wire 211.
