Electric Mosquito Zapper Circuit

For the purpose of learning i have tear down a small mosquito zapper racket.

Electric mosquito zapper circuit. Check out our circuit plans for making your own indoor electric mosquito zapper. The concepts of electronic mosquito repellers are simple and we can build a simple mosquito repellent circuit at home easily by using 555 timer ic and few other commonly available components. Bug zappers can lure and kill more than 10 000 insects in a single evening. This is a demonstration to replicate the mosquito racket fly swatter bug zapper high voltage circuit.

When this circuit is applied as a mosquito swatter the end terminals of the 2uf capacitor are appropriately tied or connected across the internal and the external bat mesh layers. The circuit inside these magnificent devices though is complex and involves several voltage booster stages which is finally stepped up to several thousand volts. High v oltage electric current flows through the insect and vaporizes it. Another possibility was to use a small step down transformer as a step up transformer and rectify the voltage to dc using general purpose diodes to apply to the mesh.

In doing so we are going to take out the following. The oscillator transistor used in this chinese mosquito zapper circuit is a 2n5609 which is an npn bjt having a current handling capacity of around 1 amp however other similar variants such as 8050 2n2222 d880 etc can also be tried instead of the original number in the design. Inside the handle of a mosquito killer bat contains an electric reachable battery and a circuit board. This ultraviolet fluorescent lamp is mounted in the middle of the cabinet and a pair of carefully spaced electrically insulated charged wire grids surround the light.

As the bug flies toward the light it penetrates the space between the wire mesh grids and completes the electric circuit. The meshes are placed on a plastic tennis like racket the inner mesh if where the. Hoont powerful electric indoor bug. In my design i decided to build a portable bug zapper because i already had most of the parts from a useless rechargeable lantern.

This hanging bug zapper s 40 watt light does a fantastic. You often hear a loud zzzz sound when this happens. Ever want to build your own mosquito killing device. Yellow resistor black transistor red led gray diode blue capacitor brown switch or wire battery is on the left high voltage output on the right.

The design is an electric fly swatter circuit that looks like a tennis racket. I am now trying to understand how the circuit is working which goal is to produce high voltage. A mosquito killer bat is also called electric flyswatter mosquito bat racket zapper or zap racket these devices are hand held and similar to look badminton racket or tennis racket.
