Description
Technical field
The utility model relates to automatic control ignition device field, is specifically related to a kind of fireworks and firecrackers radio remote control device for igniting of small-sized household.
Background technology
When traditional festival or marriage resettlement happy event, the every family firecracker of all will setting off fireworks comes heighten atmosphere.The fireworks and firecrackers of existing each manufacturer production is all established a bit of fuse cord, needs when setting off that people's low coverage is liftoff lights with naked light.Because problems such as quality, the fuse cord of fireworks and firecrackers are too short, detonation velocity inconvenience control, when human body not away from, and the words that fireworks and firecrackers is just ignited will cause security incident, poor stability.The annual Spring Festival, the report of the injury accident that all as seen causes about the firecracker of setting off fireworks from the medium, wherein most light fireworks and firecrackers after the operator be not able to do in time to cause away from fireworks and firecrackers, it is dangerous especially particularly closely to light fireworks and firecrackers by child.
At present, only know the igniter that uses when having a kind of large-scale fireworks and firecrackers to set off, this igniter generally includes a housing, establishes a small amount of gunpowder in the housing, buries one section resistance wire (as heating wire) in the gunpowder underground, and resistance wire connects power supply by hand push button; During use the fuse cord of a collection of fireworks and firecrackers is all stretched into clamping in the housing of igniter, then, press hand push button, resistance wire (as heating wire) heating power, heat is lighted a small amount of gunpowder to ignite and is produced the sunken and high temperature of fire, thereby the fuse cord of a collection of fireworks and firecrackers is lighted simultaneously.It is to light a plurality of fireworks and firecrackers simultaneously that above-mentioned igniter mainly acts on, exempt nonsynchronous problem of lighting one by one, though it also can be used for lighting single fireworks and firecrackers from the principle, but have following defective: 1, security is not high, the operator still needs nearer from fireworks and firecrackers during operation, and igniter self is wanted detonation, and is dangerous to the operator; 2, because of igniter self has gunpowder, storage and requirements on transport height, and this kind igniter is disposable, as if too high with giving me a little single fireworks and firecrackers use cost.In sum, above-mentioned igniter is not suitable for average family.
Summary of the invention
The utility model purpose is for solving the poor stability that prior art exists, and the use cost height causes not being suitable for the technical problem of average family, and a kind of fireworks and firecrackers radio remote control device for igniting of small-sized household is provided.
For achieving the above object, the technical solution adopted in the utility model is: a kind of wireless remotecontrol fireworks and firecrackers device for igniting, form by igniter and remote controller, described igniter mainly is made up of grip slipper, heating wire, operating circuit and radio reception control circuit, described grip slipper is the hinged formation of halved body, effect has spring that halved body one end is leant between halved body, correspondence is provided with the insulation heat shield on the abutment end opposite face of grip slipper halved body, two insulation heat shields lean and form the fuse cord clamp port, are embedded heating wire at least one insulation heat shield; The contact of an above-mentioned heating wire and a contactor is in series to be connected on and constitutes operating circuit on the power supply; Described radio reception control circuit is made of the coil power on/off of the above-mentioned contactor of radio reception decoding circuit output control; Described remote controller mainly is made up of shell and radio transmitter circuit.
Related content in the technique scheme is explained as follows:
1, in the such scheme, described radio reception decoding circuit and radio transmitter circuit are prior art, specifically adopt LC oscillating circuit or crystal oscillating circuit all can, also can adopt the existing integrated circuits chip.Be preferably the radio transmitter circuit and the main radio reception decoding circuit that constitutes by the PT2272 chip that adopt PT2262 chip and peripheral circuit to constitute.
2, in the such scheme, the corresponding fuse cord caulking groove that offers the U type on the one or both sides in the described fuse cord clamp port place two insulation heat shield opposite faces, expose heating wire on this caulking groove bottom land, live fuse cord to guarantee reliable clamping location, and heating wire is directly contacted with fuse cord, so that ignite fuse cord.
3, in the such scheme; in the described igniter; above-mentioned operating circuit and radio reception control circuit can be placed on outside the grip slipper; for compact conformation the best is that operating circuit and radio reception control circuit all are packaged in grip slipper inside; the two halves sheet of grip slipper can adopt metal or highstrenghtpiston to make, or the anti-protective sleeve of outsourcing, so that the igniter monolithic case is firm; can sustain the impact that fires of fireworks and firecrackers, the guarantee point firearm can be repeatedly used.
4, in the such scheme, described igniter shell can be designed to various animals shaped, increases interesting.
The utility model design concept and operation principle are: the utility model adopts the radio control technology, control electrothermal wire heating, thereby the fuse cord of the fireworks and firecrackers that ignites.During use, the operator can be placed on fireworks and firecrackers and set off the place; Then its fuse cord is stuck in the U type caulking groove on the clamp port of grip slipper of the utility model igniter, it is clamped, fuse cord is contacted with heating wire with grip slipper; Follow again, the operator retreats to the place of safety away from fireworks and firecrackers, press the firing button on the remote controller, make the radio transmitter circuit in the remote controller send instruction, radio reception decoding circuit in the igniter receives instruction output carries relay coil, thereby the action of the contact of the relay in the operating circuit makes the heating wire energising send a large amount of heats, and this heat concentrates on the fuse cord up-igniting fuse cord of fireworks and firecrackers.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1, because the utility model utilizes electrothermal wire heating's fuse cord that directly ignites, do not have gunpowder, self non-detonating, security is good, and its transportation, storage do not have specific (special) requirements yet, can be repeatedly used, and use cost is low, and the tool economy is applicable to average family;
2, because the utility model adopts wireless remote control technology, can operated from a distance, security improves greatly.
