Description
[technical field]
The present invention relates to a kind of electronic pest repelling device.
[background technology]
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 the multiple disease that causes.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.
[summary of the invention]
The present invention constitutes by moulding lid, base, coil device, circuit board and plug, and coil device and circuit board are loaded on to be moulded in the lid, and circuit board is by serial counter U

[embodiment]
The present invention covers 1 by moulding, base 2, coil device 3, circuit board 4 constitute with plug 5, and coil device 3 is loaded on to mould with circuit board 4 and cover in 1, with rivet 8 with base 2 and mould and cover 1 and rivet tightly.Circuit board 4 is by serial counter U
1, photoelectricity coupling electronic switch U
2, coil L and relevant adjunct circuit form, adjunct circuit comprises indicator lamp flasher circuit, anti-jamming circuit, light silicon controlled rectifier protecting circuit, reveals circuit, wherein the indicator lamp flasher circuit is by LED

2Decide.Therefore, in a single day the present invention 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 dead.The present invention can produce this modulated electromagnetic wave, so can reach the harmful purpose of going out, this product is through power test and test of electromagnetic disturbance, 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.
