Description

Passive type DC pulse electronics mousetrap

The utility model relates to a kind of electronics mousing equipment, particularly makes the electronics mousing equipment of dc source with dry cell.

In a lot of agriculture breeding occasions, need carry out wilderness and flow and to kill mouse, adopting the electric fishing of direct current mousetrap is the method for a kind of efficient height, instant effect.The high-tension electricity of existing DC electronic mousetrap mousing usefulness is mainly obtained the lifting of dc low-voltage electricity by the DC converting stepup transformer, and the DC converting stepup transformer is divided into two kinds of low-and high-frequency; Low frequency be about tens hertz, can be directly used in electric mouse after promoting high pressure, effect is pretty good; But the step-up transformer iron core is a silicon steel sheet, and volume is big, weight is big, and transformer technique for coiling difficulty is big; Being about more than 10000 hertz of high frequency, the step-up transformer iron core can be used high frequency magnetic core, and volume is little, in light weight, and the transformer technique for coiling is simple, but high frequency voltage must become direct current through rectifier filter, to overcome the problem of high-frequency electrical piezoelectricity mouse weak effect.No matter but belong to the mousetrap of which kind of DC converting stepup transformer, it is all in running order to keep the whole electric fishing process of catching with electric mouse, keep and catch zero load and still have bigger power consumption, and the real mouse time of getting an electric shock is caught the time much shorter more than keeping, this just makes most electric energy waste, thereby power supply can only adopt the use of charging repeatedly of the accumulator of larger capacity, thereby causes the weight of mousetrap big, the price height influences economy and portability that direct current kills rats.

Task of the present utility model is the shortcoming that overcomes above-mentioned DC electronic mousetrap, provides a kind of available dry cell to make power supply, keeps the not passive type DC pulse electronics mousetrap of consumed power that shuts down automatically when catching zero load.

The purpose of this utility model is achieved in that the utility model also has DC converting stepup transformer, rectifier filter and output indicating circuit, also has a starting impulse controller, the starting impulse controller is connected in the high pressure output loop, make power supply with 24 volts of dry cells, the duty of DC converting stepup transformer is controlled by the starting impulse controller, be connected to a dry-reed relay (also available other midget relay) and a diode in the starting impulse controller, this diode is connected on the end of high pressure output loop, and identical with the closure of kenotron.The coil tandem of dry-reed relay or is connected on before the diode in the starting impulse controller between high-voltage rectifying wave filter and output indicating circuit.

Because the utility model has the starting impulse controller, particularly is connected to a dry-reed relay and a diode in the starting impulse controller, this diode is serially connected in the end of high pressure output loop, and direction is identical with the closure of kenotron.Thereby keeping when catching state, the blocking effect of this diode makes and starts triode and be in and end, thus mousetrap being reached keep catches not power consumption of state, and when normal startup, the forward conduction effect of this diode provides passage for output current again.The dry-reed relay coil seals in output circuit, utilizes the method for output current restriction output generation pulse simple, strengthens the mousing effect, reduces power consumption, and dry cell is achieved as power supply.

Be described in further detail below in conjunction with drawings and Examples.

Fig. 1 is a structured flowchart of the present utility model.Fig. 2 is the electrical schematic diagram of an embodiment of the utility model.

With reference to Fig. 1, the utility model slightly 4 is combined by starting impulse controller 1, DC converting stepup transformer 2, rectifier filter 3 and output indication electricity, by dc source 5 to above-mentioned circuit supply.In Fig. 2, the coil J of dry-reed relay, capacitor C1, C2, C6, diode D1, resistor R 1, R2, R3, R4, R12, neon lamp Z and triode T1, T2 constitute starting impulse controller 1.Triode T3, T4, T5, coil L, capacitor C3, C4, C5, C7, resistor R 5, R6, R7, R8, R9 and transformer B1, B2 constitute DC converting stepup transformer 2.Diode D2 and capacitor C8 constitute rectifier filter 3.Resistor R 10, R11 and light emitting diode D3, D4 then constitute output indicating circuit 4.K switch, capacitor C9 and dry cell V constitute 24 volts of dc sources 5.JX1 and JX2 are external metal bare wire binding post.External metal bare wire binding post also can be for one or more.

When power switch K connects, because the blocking-up of D1, T1, T2 end, T3 instead ends partially, and the pulse oscillator that T3 and peripheral cell thereof constitute is not worked, and T4, T5 all end, thereby complete machine is in idle state of catching of keeping, consumed power not, complete machine leakage current this moment 1-3 μ A only, power consumption＜0.00001W.

When the metal bare wire is touched by mouse, because B2 secondary high pressure coil one terminates on the positive source, cathode voltage passes through high-tension coil, commutation diode D2 and output indicating circuit 4 arrive the metal bare wire, by the mouse body, the earth, the coil J of dry-reed relay and resistor R 1, R2, R3 is added to triode T1, the base stage of T2, owing to be connected to capacitor C2 between the base stage of T1 and ground, voltage can not suddenly change, conducting is delayed, T2 is conducting at first, make T3 be in positively biased, T3 and L, C4, C3, C5, R8, R5, R6, the oscillating circuit output high-frequency impulse that R7 constitutes, T4 amplifies it, T5 is energized and enters duty, B2 level output high-frequency and high-voltage, and by D2, the filtering of C8 halfwave rectifier becomes high direct voltage and delivers to the metal bare wire through indicating circuit, and high-tension current is through the mouse body, the earth, the coil J of dry-reed relay is back to B2 the level other end with diode D1 and becomes the loop.When flowing through diode D1, form 0.7 volt of pressure drop, make T2 moment enter saturation conduction, thereby make T3 enter metastable oscillatory work state, promote the stable output of high pressure, because flowing through, big high-tension current produced enough magnetic field again during the coil J of dry-reed relay, the contact J1 of dry-reed relay is connected, voltage on the C2 bleeds off through the contact J1 and the transformer B1 secondary coil of dry-reed relay over the ground by R3 at this moment, making T1 continue to keep ends, simultaneously, the pulse voltage of B1 level of driving transformer, also by J1 and the negative-feedback of C6 electric capacity to the base stage that promotes triode T4, cause the promotion stage gain to plummet suddenly, so that the T5 switching power tube can not get enough driving voltage work and ends, thereby high pressure output is interrupted suddenly, the coil J of dry-reed relay loses high-tension current, magnetic field suddenly disappears, contact J1 disconnects, feedback stops, circuit is resumed work immediately, and high-tension current produces again, and J1 connects again, so continuous circulation has just formed about tens hertz low frequency high direct voltage pulse current output.Sound that the contact J1 break-make of dry-reed relay forms and high pressure output indicator be luminous to can be used as electric mouse and reports to the police.More than be that mouse touches the startup electricity mouse process that this mousetrap is finished behind the line.After dusk, mouse was removed, high-tension current opens circuit, J1 can only be in off-state, and this moment, high pressure made D1 still keep 0.7 volt of pressure drop by Z, R12 neon lamp circuit, and the last voltage of C2 is not owing to there is the dry-reed relay connection to bleed off, rise to 0.7 volt of T1 conducting through about 0.2 second voltage, forcing the T2 base potential is zero to cut-off, and the T3 base stage is instead ended partially, and T4, T5 disappear by high pressure, complete machine recovers not work, not power consumption keep the state of catching, wait for the arrival of next mouse.

What adopt among Fig. 2 embodiment is that anodal the triggering starts, forward output, in like manner also can adopt negative pole to trigger to the circuit appropriate change starts, negative pole output, but it is identical with kenotron D2 direction constant all the time that the diode D1 in the impulse controller is serially connected in end, its D1 direction of high pressure output loop, and negative pole triggers to start promptly becomes another embodiment.The coil J of dry-reed relay can be connected between high-voltage rectifying wave filter and the output indicating circuit, also can be connected on (as shown in Figure 2) before the diode D1 in the starting impulse controller, and its effect is the same.

The startup effective sensitivity of this device generally can reach 200k Ω, and when the output loading of 200k Ω, crest voltage can reach 1800 volts, electric current has only 30-50mA during output short-circuit, and the mouse of can hitting unconsciously is to people, animal safety, this moment, the static current of lcd of complete machine had only 0.35-0.6A, and power is less than 15W; Has the effect that kills rats preferably in the bare wire length 100m scope.In interrupted the trying out of about half a year, the mousing amount of one group of dry cell reaches more than 200, and better economic, light practicality are arranged.Not only be fit to do the mobile mousing in wilderness, and can make the electric fence captive livestock.
