Description
Affiliated technical field
The utility model relates to a kind of high-voltage pulse that utilizes and discharges the device that the quick-fried sound of charge generation on the energy-storage capacitor and electric light imitate firecrackers or salvo firework display effect.
Background technology
At present, the someone has invented a kind of device of thunder and lightning formula electronic firecracker that cries and has replaced the gunpowder firecrackers, and its circuit diagram as shown in Figure 1.General principles is: power for illumination is divided into two-way after the heap D1 that passes a bridge is rectified into direct current about 300 volts, the one tunnel for energy storage electrochemical capacitor C2 charging, and another road is for impulse circuit generation high-voltage pulse.Two electrodes of energy storage electrolytic capacitor C2 are electrically connected the electrode bar (also being called fried silk) of two one determining deviations respectively; In a side of electrode bar line, place a high-field electrode rod that is connected with high-voltage pulse; After energy storage electrochemical capacitor C1 is charged, regulate the distribution interval of three rods; High-voltage pulse is continuous ionized air between positive and negative two electrodes, constantly discharges the continuous empty detonans of charge generation on the energy storage electrochemical capacitor C1.The sound size of firecrackers is relevant with the size of storage capacitor C1, and the big more then sound of capacitance is high more.Some businessmans are placed on said apparatus in the anistree box now, and the box below is hung some and decorated cylinder, makes thunder and lightning formula electronic firecracker.But there is following deficiency in this product: the first, can only be in indoor use.As want that in outdoor application general thinking is with inverter the dc inverter of storage battery to be become alternating current, uses for firecrackers again.But because of the firecrackers circuit is capacitive load and bigger charging or discharging current is arranged, existing commercial inverter very is not fit to such load, has therefore limited its outdoor application; The second, firecrackers sound is little.Though can increase explosive sound by increasing energy storage electrochemical capacitor C1, also make the charge density of fried silk discharge end excessive, increase the discharge difficulty, cause regular miso-fire, causing can not continuous quick-fried sound; Three, electrode bar causes discharging gap to increase and the quick-fried sound that can not discharge through repeatedly quick-fried sound can be ablated.Four, behind continuous quick-fried sound, the energy-storage capacitor heating is severe, fragile.
Summary of the invention
In order to overcome the deficiency of existing artificial electronic firecrackers, salvo, the utility model provides a kind of alterating and direct current dual-purpose type electronic firecracker.This electronic firecracker has also increased storage battery, high frequency current limiter, has strengthened capacitor energy, special-purpose high-frequency inverter circuit, active thermal protection circuit except still containing current limiter, rectifier, capacitor energy, impulse generator, improved discharge head.It is characterized in that: according to the different electrical power type, receive different current limiters with change-over switch, the current limiter step-down, the rectifier output dc voltage, rectification is exported on one side to energy-storage capacitor that links to each other with fried silk and the charging of enhancing energy-storage capacitor, drive-pulse generator produces high-voltage pulse simultaneously, and high-voltage pulse outputs to the high-field electrode rod, ignites the quick-fried sound of discharge head.Concrete technical scheme division is as follows:
1) solves the existing little problem of electronic firecracker sound.The one, increase one or more groups and strengthened capacitor energy storage circuit.Strengthen capacitor energy storage circuit and also forms, in discharge head, lay mutually on the same group the fried silk of number (layered arrangement is up and down adopted in the locus, is in same one deck with a pair of) simultaneously, connect with the enhancing capacitor electrode respectively by rectifier, storage capacitor.Increase the fried silk of discharge the group number be to reduce fried silk discharge end charge density; The 2nd, adopt voltage-multiplying circuit to improve each to the voltage (being increased to more than 500 volts) between fried silk by existing 300 volts; The 3rd, below fried silk, lay a permanent magnetism stone, in order to latent electricity from air, reduce a fried silk discharge difficulty.
2) solve easily ablation problem of the fried silk of existing artificial electronic firecrackers.Employing is riveted the electrode contact of anti-ablation at fried silk discharge end, or adopts removable fried silk discharge end, reaches the service life that prolongs quick-fried loud device.
3) solve the outdoor application problem.Designed special-purpose high-frequency inverter, it is made up of battery, PWM pulse-width modulation circuit, push-pull type on-off circuit, high-frequency step-up transformer.Pulse-width modulation circuit output high frequency (greater than 30MHz) trigger impulse, the push-pull type on-off circuit that promotion is made up of FET produces alternating current, and being boosted to export by high-frequency step-up transformer again is higher than 30 megahertzes, voltage is directly made power supply for firecrackers greater than 100 volts alternating current.Dual-purpose in order to reach alterating and direct current, a high frequency current limiter (coil or electric capacity) in parallel on the current limiter of original firecrackers circuit, and with change-over switch realize exchanging, direct current uses conversion.
4) this device has also increased the protective device that initiatively generates heat, and the working time of control device and time of having a rest, makes the storage capacitor heating temp be no more than rated value.It is made up of active heating element and closed type bimetal leaf temperature switch.After firecrackers were started working, initiatively the heating element temperature raise, and when temperature was higher than the temperature switch inversion temperature, temperature switch cut off the firecrackers power supply.When treating that initiatively the heating element temperature is lower than the temperature switch inversion temperature, temperature switch recloses the firecrackers power supply, and firecrackers can have been worked again.
5) increase reverberation effect.Fried silk spacing can influence strength of discharge and discharge frequency, and the big frequency of spacing is little, the intensity height, otherwise otherwise then.In view of the above, fried of each group is arranged to different arcing distances, and is all different with quick-fried loud frequency to reach the quick-fried loud intensity of discharging between the fried silk of each group, and big small voice reverberation effect is arranged.
The beneficial effects of the utility model are, explosive sound is bigger when using onesize storage capacitor total amount, and quick-fried sound has higher success rate; The commutativity of fried silk discharge end has increased the service life of installing; The heat protection is arranged, improved the reliability of device; Increase special-purpose inverter circuit, realized the purpose of outdoor mobile use.
