Abstract
The utility model relates to an electronic insect expeller which is composed of a plastic cover, a pedestal, a coil device, a circuit board and a plug. The coil device and the circuit board are installed in the plastic cover. The circuit board is composed of a serial counter U1, a photoelectric coupling electronic switch U2, a wire coil L and relevant additional circuits. A position which is close to one end of the coil device has an outward bulge, the plug is arranged in the bulge, wire heads of a red wire and a black wire of the other end of the plug are respectively welded on the wiring position of a power supply of the circuit board, and two leading wires of the coil device are respectively welded on the corresponding position of the circuit board. The utility model has the advantages of small volume, beautiful appearance and easy use, and can effectively kill mice, cockroaches and other noxious animals.
Description
The utility model relates to a kind of electronic pest repelling device.
Insect such as mouse, cockroach is the serious day by day problem in the whole world, eats up every year and pollutes millions of ton-grain food, destroys tens yuan property, propagates multiple fatal diseases.The evil of going out at present extensively adopts spray, bait formulation or the smog of the poisonous chemical agent of agrochemical, and is not only harmful, and muroid, cockroach can develop immunity to drugs soon and make chemical agent lose effectiveness, do not reach satisfied effect.
The purpose of this utility model is to provide a kind of electronic pest repelling device that utilizes low frequency electromagnetic field to kill mouse, cockroach.
The utility model is to realize like this, it constitutes by moulding lid, base, coil device, circuit board and plug, coil device and circuit board are loaded on to be moulded in the lid, and coil device comprises coil, fin, nut, plain washer and saw out the lock pad volume outward that circuit board is by serial counter U
1, photoelectricity coupling electronic switch U
2, coil of wire L, indicator lamp flasher circuit LED
1And R
5, anti-jamming circuit C
4, light silicon controlled rectifier protecting circuit C
3, R

6Form; To outer lug, be provided with plug near coil device one end in the projection, the red line of the plug other end and the end of a thread of black line are welded on respectively on the position of circuit board power supply wiring, and two lead-in wires of coil device also are welded on respectively on the circuit board correspondence position.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the circuit diagram of the utility model.
The utility model constitutes with plug (5) by moulding lid (1), base (2), coil device (3), circuit board (4), and coil device (3) is loaded on circuit board (4) and moulds in the lid (1), with rivet (8) with base (2) and mould lid (1) and rivet tightly.Coil device (3) comprises coil, fin, nut, plain washer and saws out the lock pad volume outward that circuit board (4) is by serial counter U
1, photoelectricity coupling electronic switch U
2, coil of wire L and relevant adjunct circuit form, adjunct circuit comprises indicator lamp flasher circuit, anti-jamming circuit, light silicon controlled rectifier protecting circuit, leakage circuit, wherein the indicator lamp flasher circuit is by LED

2Decide.Therefore, in a single day the utility model inserts power supply, just produces this modulated electromagnetic wave immediately and go round and begin again to work without cessation.
For a long time physiology and the habit research of insects such as mouse and cockroach are reached a conclusion according to the biologist, carrier frequency is the constant amplitude sine of the 50HZ electromagnetic wave that is subjected to the secondary square-wave frequency modulation has direct interference effect to the metabolism of mouse and insect, the low frequency electromagnetic field of its generation is in a certain distance scope that is furnished with civil power (220V50HZ) electric wire building, changed the electromagnetic field of original wiring, this electromagnetic field extends to wall along electric wire, ceiling and window, in the crack of cabinet, cause the metabolism that has influence on cockroach and mouse, the normal fecundity of cockroach and mouse and the Natural Circulation of feed have been changed, stop cockroach and mouse to be nested indoor, breeding, finally reach expulsion cockroach and mouse, so that the apocleisis dehydration is until death.The utility model can produce this modulated electromagnetic wave, so can reach the harmful purpose of going out, this product through power test and electromagnetism in disturbing test, proof meets safety requirements, its induction is very little, can not influence the metabolic function of human beings'health and general animal, to household electrical appliance and the yet noiseless effect of computer.
The utility model volume is little, good looking appearance, easy to use, can effectively kill noxious animals such as mouse, cockroach.
