Specific embodiment

The utility model is described in further detail in the following with reference to the drawings and specific embodiments.

As shown in Figure 1, a kind of safe electronic fly-killing device, including shell, the shell are equipped with the metal of equidistant parallel Silk power grid, it is characterised in that: rectification circuit, high-frequency oscillating circuits and discharge circuit are equipped in the shell；

The working principle of the utility model is as follows: triode BG1, BG2, BG3 form high frequency oscillator, and oscillating voltage is through two Pole pipe D1 rectifies the base stage for adding to triode BG2, so that triode BG2 and BG3 conducting saturation.Circuit is given by potentiometer RP2 Capacitor C7 charging.Unijunction transistor BG4 forms relaxation oscillator, and controllable silicon SCR is connected in trigger pulse, and capacitor C8 is boosted Transformer B2 primary and controllable silicon SCR electric discharge, when discharge current zero passage, controllable silicon SCR shutdown, capacitor C8 is recharged.When can Silicon SCR conducting is controlled, capacitor C8 discharges again.The high-voltage pulse of thousands of volts is thus generated in the secondary of step-up transformer B2. Fly falls on power grid, and body touches power grid, makes its two adjacent wire short circuits, capacitor is discharged by fly body, by it It kills.After corpse is fallen, capacitor charging rapidly again, metal power system restoration high pressure.

If human body touches accidentally at this time, due to the presence of human body distribution capacity, it is equivalent to triode BG1 oscillation circuit L, C3 has added a capacitor, destroys starting condition for oscillation, makes circuit failure of oscillation.Once the loss of voltage in triode BG2 base stage is added to, Triode BG2, BG3 cut-off, the both ends resistance R7 become low potential, unijunction transistor BG4 failure of oscillation, and no trigger pulse triggers are silicon-controlled SCR, high pressure disappear, play a protective role.
