Electronic mosquito shoot hereinafter referred to as "electric mosquito swatter", to use, convenient, actually kill mosquitoes, flies and moths, etc.) effect is good, no chemical pollution, and the advantages of safety and health, become a summer selling small home appliance product. Electric mosquito swatter, high-capacity lead-acid rechargeable battery using 4 v or 2.4 v nimh/nicd battery, also useful dry cell.

      The booster circuit in double-layer grid generation between 1850 v dc high voltage (current is less than 10 ma, harmless to human and animal), the electrostatic field between the two grids has the strong adsorbability, when the insect pest such as close to the power grid, can put them between suction power grid, the short circuit current and then will be electricity dead; Flies shoot at the same time electricity produced by high voltage can release a certain amount of negative oxygen ions, as well as sterilization, and can purify the air. Has gradually become an indispensable tool for summer extermination.

      It is mainly composed of three times the pressure high-frequency oscillation circuit, rectifier circuit and high voltage electric shock DW of three parts. When press the power switch SB, composed of high frequency transistor VT and transformer T oscillator electricity work, about 3 v dc into 18 KHZ high frequency alternating current, the T step up to about 800 v (discharge distance estimation), then through diode VD2 ~ VD4 three times the voltage rectifier, capacitor C1 and C3 increase to about 2500 v, added to the mosquito swatter metal mesh DW. Worm when flies touch the high voltage grid power grid caused by short circuit, which are current, arc burning or stun or kill.

      Circuit, light emitting diode VD1 and current-limiting resistor R1 indicator light circuit, used to indicate circuit on-off state and display the battery electrical energy loss.
